Evaluation of the Quality of ED Management for Patients with COPD.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is associated with exacerbations and high risk of serious outcomes. Our goal was to determine the appropriateness of the ED management of COPD exacerbations. METHODS: This observational cohort study incorporated a health records review and included COPD exacerbation cases seen at two large academic EDs. We included all patients with the primary diagnosis of COPD exacerbation. From the electronic medical record, demographic and clinical data were abstracted, and the Ottawa COPD Risk Score (OCRS) was calculated for each. Short-term serious outcomes (SSO) included ICU admission, intubation, myocardial infarction, non-invasive positive pressure ventilation (NIV), and death at 30 days. Cases were judged for appropriateness of treatment according to explicit indications and standards developed a priori. RESULTS: We enrolled 500 cases with mean age 71.9, female 51.2%, admitted 50.2%, and death 4.4%. The calculated OCRS score was >2 for 70.8% of patients. The treatments provided were inhaled beta-agonists (82.6%), inhaled anticholinergics (76.6%), corticosteroids (75.2%), antibiotics (71.0%), oxygen (63.8%), NIV (8.8%) and intubation (0.6%). Overall, 50.0% of cases were judged to have had inadequate management due to missing treatments. Specifically, the proportion of missing treatments were inhaled beta agonist (17.0%), inhaled anticholinergic (22.6%), corticosteroids (24.4%), antibiotics (12.8%), and NIV (2.0%). CONCLUSIONS: Adequate treatment of COPD exacerbation was lacking in 50.0% of patients in these two large academic EDs. Concerning were the number of patients not receiving corticosteroids or antibiotics. Implementation of explicit treatment standards should lead to improved patient care of this common and serious condition.

Dequalinium chloride vaginal tablets for recalcitrant Trichomonas vaginalis: A case report.

Treatment options for recalcitrant Trichomonas vaginalis (TV), when very high dose systemic 5-nitroimidazole plus intravaginal therapy for over 14 days has failed, are very limited. They have poor efficacy, unpleasant side effects, and are difficult and expensive to acquire. We report successful treatment with 24 weeks of daily dequalinium chloride vaginal tablets. Dequalinium is licensed in Europe where it is readily available and cheap. It offers a safe and pragmatic alternative for recalcitrant TV.

Effectiveness of septoplasty compared to medical management in adults with obstruction associated with a deviated nasal septum: the NAIROS RCT.

Background: The indications for septoplasty are practice-based, rather than evidence-based. In addition, internationally accepted guidelines for the management of nasal obstruction associated with nasal septal deviation are lacking. Objective: The objective was to determine the clinical effectiveness and cost-effectiveness of septoplasty, with or without turbinate reduction, compared with medical management, in the management of nasal obstruction associated with a deviated nasal septum. Design: This was a multicentre randomised controlled trial comparing septoplasty, with or without turbinate reduction, with defined medical management; it incorporated a mixed-methods process evaluation and an economic evaluation. Setting: The trial was set in 17 NHS secondary care hospitals in the UK. Participants: A total of 378 eligible participants aged > 18 years were recruited. Interventions: Participants were randomised on a 1: 1 basis and stratified by baseline severity and gender to either (1) septoplasty, with or without turbinate surgery (n = 188) or (2) medical management with intranasal steroid spray and saline spray (n = 190). Main outcome measures: The primary outcome was the Sino-nasal Outcome Test-22 items score at 6 months (patient-reported outcome). The secondary outcomes were as follows: patient-reported outcomes - Nasal Obstruction Symptom Evaluation score at 6 and 12 months, Sino-nasal Outcome Test-22 items subscales at 12 months, Double Ordinal Airway Subjective Scale at 6 and 12 months, the Short Form questionnaire-36 items and costs; objective measurements - peak nasal inspiratory flow and rhinospirometry. The number of adverse events experienced was also recorded. A within-trial economic evaluation from an NHS and Personal Social Services perspective estimated the incremental cost per (1) improvement (of ≥ 9 points) in Sino-nasal Outcome Test-22 items score, (2) adverse event avoided and (3) quality-adjusted life-year gained at 12 months. An economic model estimated the incremental cost per quality-adjusted life-year gained at 24 and 36 months. A mixed-methods process evaluation was undertaken to understand/address recruitment issues and examine the acceptability of trial processes and treatment arms. Results: At the 6-month time point, 307 participants provided primary outcome data (septoplasty, n = 152; medical management, n = 155). An intention-to-treat analysis revealed a greater and more sustained improvement in the primary outcome measure in the surgical arm. The 6-month mean Sino-nasal Outcome Test-22 items scores were -20.0 points lower (better) for participants randomised to septoplasty than for those randomised to medical management [the score for the septoplasty arm was 19.9 and the score for the medical management arm was 39.5 (95% confidence interval -23.6 to -16.4; p < 0.0001)]. This was confirmed by sensitivity analyses and through the analysis of secondary outcomes. Outcomes were statistically significantly related to baseline severity, but not to gender or turbinate reduction. In the surgical and medical management arms, 132 and 95 adverse events occurred, respectively; 14 serious adverse events occurred in the surgical arm and nine in the medical management arm. On average, septoplasty was more costly and more effective in improving Sino-nasal Outcome Test-22 items scores and quality-adjusted life-years than medical management, but incurred a larger number of adverse events. Septoplasty had a 15% probability of being considered cost-effective at 12 months at a £20,000 willingness-to-pay threshold for an additional quality-adjusted life-year. This probability increased to 99% and 100% at 24 and 36 months, respectively. Limitations: COVID-19 had an impact on participant-facing data collection from March 2020. Conclusions: Septoplasty, with or without turbinate reduction, is more effective than medical management with a nasal steroid and saline spray. Baseline severity predicts the degree of improvement in symptoms. Septoplasty has a low probability of cost-effectiveness at 12 months, but may be considered cost-effective at 24 months. Future work should focus on developing a septoplasty patient decision aid. Trial registration: This trial is registered as ISRCTN16168569 and EudraCT 2017-000893-12.

Septoplasty is an operation to straighten the septum, which is the partition wall between the nostrils inside the nose. Septoplasty can be used as a treatment for people who have a bent septum and symptoms of a blocked nose, such as difficulty sleeping and exercising. Medical management (a saltwater spray to clear the nose followed by a nose steroid spray) is an alternative treatment to septoplasty. The Nasal AIRway Obstruction Study (NAIROS) aimed to find out whether septoplasty or medical management is a better treatment for people with a bent septum and symptoms of a blocked nose. We recruited 378 patients with at least moderately severe nose symptoms from 17 hospitals in England, Scotland and Wales to take part in the NAIROS. Participants were randomly put into one of two groups: septoplasty or medical management. Participants' nose symptoms were measured both when they joined the study and after 6 months, using a questionnaire called the Sino-nasal Outcome Test-22 items. This questionnaire was chosen because patients reported that it included symptoms that were important to them. Other studies have shown that a 9-point change in the Sino-nasal Outcome Test-22 items score is significant. After 6 months, on average, people in the septoplasty group improved by 25 points, whereas people in the medical management group improved by 5 points. We saw improvement after septoplasty among patients with moderate symptoms, and among those with severe symptoms. Most patients who we spoke to after a septoplasty were happy with their treatment, but some would have liked more information about what to expect after their nose surgery. In the short term, septoplasty is more costly than medical management. However, over the longer term, taking into account all the costs and benefits of treatment, suggests that septoplasty would be considered good value for money for the NHS.

Clinical effectiveness of septoplasty versus medical management for nasal airways obstruction: multicentre, open label, randomised controlled trial.

OBJECTIVE: To assess the clinical effectiveness of septoplasty. DESIGN: Multicentre, randomised controlled trial. SETTING: 17 otolaryngology clinics in the UK's National Health Service. PARTICIPANTS: 378 adults (≥18 years, 67% men) newly referred with symptoms of nasal obstruction associated with septal deviation and at least moderate symptoms of nasal obstruction (score >30 on the Nasal Obstruction and Symptom Evaluation (NOSE) scale). INTERVENTIONS: Participants were randomised 1:1 to receive either septoplasty (n=188) or defined medical management (n=190, nasal steroid and saline spray for six months), stratified by baseline symptom severity and sex. MAIN OUTCOME MEASURES: The primary outcome measure was patient reported score on the Sino-Nasal Outcome Test-22 (SNOT-22) at six months, with 9 points defined as the minimal clinically important difference. Secondary outcomes included quality of life and objective nasal airflow measures. RESULTS: Mean SNOT-22 scores at six months were 19.9 (95% confidence interval 17.0 to 22.7) in the septoplasty arm (n=152, intention-to-treat population) and 39.5 (36.1 to 42.9) in the medical management arm (n=155); an estimated 20.0 points lower (better) for participants randomised to receive septoplasty (95% confidence interval 16.4 to 23.6, P<0.001, adjusted for baseline continuous SNOT-22 score and the stratification variables sex and baseline NOSE severity categories). Greater improvement in SNOT-22 scores was predicted by higher baseline symptom severity scores. Quality of life outcomes and nasal airflow measures (including peak nasal inspiratory flow and absolute inhalational nasal partitioning ratio) improved more in participants in the septoplasty group. Readmission to hospital with bleeding after septoplasty occurred in seven participants (4% of 174 who had septoplasty), and a further 20 participants (12%) required antibiotics for infections. CONCLUSIONS: Septoplasty is a more effective intervention than a defined medical management regimen with a nasal steroid and saline spray in adults with nasal obstruction associated with a deviated nasal septum.

Conservative management versus tonsillectomy in adults with recurrent acute tonsillitis in the UK (NATTINA): a multicentre, open-label, randomised controlled trial.

BACKGROUND: Tonsillectomy is regularly performed in adults with acute tonsillitis, but with scarce evidence. A reduction in tonsillectomies has coincided with an increase in acute adult hospitalisation for tonsillitis complications. We aimed to assess the clinical effectiveness and cost-effectiveness of conservative management versus tonsillectomy in patients with recurrent acute tonsillitis. METHODS: This pragmatic multicentre, open-label, randomised controlled trial was conducted in 27 hospitals in the UK. Participants were adults aged 16 years or older who were newly referred to secondary care otolaryngology clinics with recurrent acute tonsillitis. Patients were randomly assigned (1:1) to receive tonsillectomy or conservative management using random permuted blocks of variable length. Stratification by recruiting centre and baseline symptom severity was assessed using the Tonsil Outcome Inventory-14 score (categories defined as mild 0-35, moderate 36-48, or severe 49-70). Participants in the tonsillectomy group received elective surgery to dissect the palatine tonsils within 8 weeks after random assignment and those in the conservative management group received standard non-surgical care during 24 months. The primary outcome was the number of sore throat days collected during 24 months after random assignment, reported once per week with a text message. The primary analysis was done in the intention-to-treat (ITT) population. This study is registered with the ISRCTN registry, 55284102. FINDINGS: Between May 11, 2015, and April 30, 2018, 4165 participants with recurrent acute tonsillitis were assessed for eligibility and 3712 were excluded. 453 eligible participants were randomly assigned (233 in the immediate tonsillectomy group vs 220 in the conservative management group). 429 (95%) patients were included in the primary ITT analysis (224 vs 205). The median age of participants was 23 years (IQR 19-30), with 355 (78%) females and 97 (21%) males. Most participants were White (407 [90%]). Participants in the immediate tonsillectomy group had fewer days of sore throat during 24 months than those in the conservative management group (median 23 days [IQR 11-46] vs 30 days [14-65]). After adjustment for site and baseline severity, the incident rate ratio of total sore throat days in the immediate tonsillectomy group (n=224) compared with the conservative management group (n=205) was 0·53 (95% CI 0·43 to 0·65; <0·0001). 191 adverse events in 90 (39%) of 231 participants were deemed related to tonsillectomy. The most common adverse event was bleeding (54 events in 44 [19%] participants). No deaths occurred during the study. INTERPRETATION: Compared with conservative management, immediate tonsillectomy is clinically effective and cost-effective in adults with recurrent acute tonsillitis.

Screening for silent aspiration in hyperacute stroke: A feasibility study of clinical swallowing examination and cough reflex testing.

BACKGROUND: Silent aspiration (SA) is common post-stroke and associated with increased risk of pneumonia, length of stay and healthcare costs. Clinical swallow examinations (CSEs) are unreliable measures of SA. There is no consensus on the clinical components that best detect SA. Cough reflex testing (CRT) is an alternative/adjunct whose SA detection accuracy also lacks consensus. AIMS: To investigate the feasibility of CSE versus CRT against gold standard flexible endoscopic evaluation of swallowing (FEES) for SA identification and to estimate its prevalence in a hyperacute stroke setting. METHODS & PROCEDURES: A single-arm preliminary, prospective, feasibility study of patients less than 72 h post-stroke, over a 31-day period on a hyperacute stroke unit: the Royal Victoria Infirmary, Newcastle-upon-Tyne, UK. Ethical approval for the study was obtained. The study tested the feasibility and acceptability of introducing CRT and developing a standardized CSE. Consent/assent was obtained for all participants. Patients unfit for study were excluded. OUTCOMES & RESULTS: A total of 62% of patients less than 72 h post-stroke (n = 61) were eligible. A total of 75% of those approached (n = 30) consented. A total of 23 patients completed all tests. The principal barrier was anxiety regarding FEES. Mean test time for CRT = 6 min; CSE = 8 min; FEES = 17 min. Patients rated CRT and FEES on average as moderately uncomfortable. A total of 30% (n = 7) of participants who received FEES presented with SA. CONCLUSIONS & IMPLICATIONS: CRT, CSE and FEES are feasible in 58% of hyperacute stroke patients in this setting. FEES anxiety is the main recruitment barrier and is not always well tolerated. Results support further work to establish optimum methods and differential sensitivity/specificity of CRT and CSE in hyperacute stroke for SA identification. WHAT THIS PAPER ADDS: What is already known on this subject SA significantly increases the risk of pneumonia in the early days post-stroke. CSEs are unreliable for identification of SA risk in this population. CRT is gaining popularity as a potential tool to identify stroke patients at risk of SA, though there are questions regarding the efficacy of the clinical protocol currently being used in the UK. What this study adds to existing knowledge This study demonstrates that it is practical and feasible to carry out a larger scale study in this setting to compare CSE and CRT including a consideration of an approach combining both methods for clinical identification of SA versus FEES. Preliminary findings suggest that CSE may have higher levels of sensitivity than CRT for SA identification. What are the potential or actual clinical implications of this work? The results of this study suggest that further work is needed to establish the optimum methods and differential sensitivity/specificity of clinical tools for SA detection in hyperacute stroke.

The utility of a symptom model to predict the risk of oesophageal cancer.

OBJECTIVE: To assess whether extra-oesophageal symptoms are predictive of oesophageal malignancy. METHODS: A prospective, single-centre cross-sectional questionnaire study at a tertiary referral unit for oesophageal cancer using the Comprehensive Reflux Symptoms Scale (CReSS) questionnaire tool. Respondents with oesophageal malignancy were compared with historical cohorts undergoing airway examination or upper gastrointestinal endoscopy and found to have benign diagnoses. We developed a model for predicting oesophageal cancer using linear discriminant analysis and logistic regression, assessed by Monte Carlo cross validation. RESULTS: Respondents with oesophageal malignancy (n = 146; mean age 70.5; male: female, 71:29) were compared with those undergoing airway examination (n = 177) and upper gastrointestinal endoscopy (n = 351), found to have benign diagnoses. No single questionnaire item, or group of co-varying items (factors), reliably discriminated oesophageal cancer from other diagnoses. Individual items which suggested higher risk of oesophageal malignancy included dysphagia (area under the curve (AUC) 0.68), low appetite (AUC 0.66), and early satiety (AUC 0.58). Conversely, throat pain (AUC 0.38), bloating (AUC 0.38) and heartburn (AUC 0.37) were inversely related to cancer risk. A forward stepwise regression analysis including a subset of 12 CReSS questionnaire items together with age and sex derived a model predictive of oesophageal malignancy in this cohort (AUC 0.89). CONCLUSION: We demonstrate a model comprised of 12 questionnaire items and 2 demographic parameters as a potential predictive tool for oesophageal malignancy diagnosis in this study population. Translating this model for predicting oesophageal malignancy in the general population is a valuable topic for future research.

Tonsillectomy compared with conservative management in patients over 16 years with recurrent sore throat: the NATTINA RCT and economic evaluation.

Background: The place of tonsillectomy in the management of sore throat in adults remains uncertain. Objectives: To establish the clinical effectiveness and cost-effectiveness of tonsillectomy, compared with conservative management, for tonsillitis in adults, and to evaluate the impact of alternative sore throat patient pathways. Design: This was a multicentre, randomised controlled trial comparing tonsillectomy with conservative management. The trial included a qualitative process evaluation and an economic evaluation. Setting: The study took place at 27 NHS secondary care hospitals in Great Britain. Participants: A total of 453 eligible participants with recurrent sore throats were recruited to the main trial. Interventions: Patients were randomised on a 1 : 1 basis between tonsil dissection and conservative management (i.e. deferred surgery) using a variable block-stratified design, stratified by (1) centre and (2) severity. Main outcome measures: The primary outcome measure was the total number of sore throat days over 24 months following randomisation. The secondary outcome measures were the number of sore throat episodes and five characteristics from Sore Throat Alert Return, describing severity of the sore throat, use of medications, time away from usual activities and the Short Form questionnaire-12 items. Additional secondary outcomes were the Tonsil Outcome Inventory-14 total and subscales and Short Form questionnaire-12 items 6 monthly. Evaluation of the impact of alternative sore throat patient pathways by observation and statistical modelling of outcomes against baseline severity, as assessed by Tonsil Outcome Inventory-14 score at recruitment. The incremental cost per sore throat day avoided, the incremental cost per quality-adjusted life-year gained based on responses to the Short Form questionnaire-12 items and the incremental net benefit based on costs and responses to a contingent valuation exercise. A qualitative process evaluation examined acceptability of trial processes and ramdomised arms. Results: There was a median of 27 (interquartile range 12-52) sore throats over the 24-month follow-up. A smaller number of sore throats was reported in the tonsillectomy arm [median 23 (interquartile range 11-46)] than in the conservative management arm [median 30 (interquartile range 14-65)]. On an intention-to-treat basis, there were fewer sore throats in the tonsillectomy arm (incident rate ratio 0.53, 95% confidence interval 0.43 to 0.65). Sensitivity analyses confirmed this, as did the secondary outcomes. There were 52 episodes of post-operative haemorrhage reported in 231 participants undergoing tonsillectomy (22.5%). There were 47 re-admissions following tonsillectomy (20.3%), 35 relating to haemorrhage. On average, tonsillectomy was more costly and more effective in terms of both sore throat days avoided and quality-adjusted life-years gained. Tonsillectomy had a 100% probability of being considered cost-effective if the threshold for an additional quality-adjusted life year was £20,000. Tonsillectomy had a 69% probability of having a higher net benefit than conservative management. Trial processes were deemed to be acceptable. Patients who received surgery were unanimous in reporting to be happy to have received it. Limitations: The decliners who provided data tended to have higher Tonsillectomy Outcome Inventory-14 scores than those willing to be randomised implying that patients with a higher burden of tonsillitis symptoms may have declined entry into the trial. Conclusions: The tonsillectomy arm had fewer sore throat days over 24 months than the conservative management arm, and had a high probability of being considered cost-effective over the ranges considered. Further work should focus on when tonsillectomy should be offered. National Trial of Tonsillectomy IN Adults has assessed the effectiveness of tonsillectomy when offered for the current UK threshold of disease burden. Further research is required to define the minimum disease burden at which tonsillectomy becomes clinically effective and cost-effective.

Tonsillectomy is an operation to take out the pair of tonsil glands at the back of the throat. It is an option for adults who suffer from repeated, severe sore throats. Adults who have a tonsillectomy say that they get fewer sore throats afterwards, but it is not clear whether or not they would have got better over time without the operation. There is pressure on doctors to limit the number of tonsillectomies carried out. At the same time, emergency hospital admissions for adults with severe throat infections have been increasing. NAtional Trial of Tonsillectomy IN Adults aimed to find out whether tonsillectomy is an effective and worthwhile treatment for repeated severe sore throats or whether patients would be better off treated without an operation. A total of 453 patients from 27 hospitals in Great Britain took part in the study. Patients were assigned at random to receive either tonsillectomy or conservative management (treatment as needed from their general practitioner). We measured how many sore throats patients had in the next 2 years by sending them text messages every week. We asked about the impact of their sore throats on their quality of life and time off work, and looked at the costs of treatment. We also interviewed 47 patients, general practitioners and hospital staff about their experiences of tonsillectomy and NAtional Trial of Tonsillectomy IN Adults. The typical patient in the tonsillectomy arm had 23 days of sore throat compared with 30 days of sore throat in the conservative management arm. Tonsillectomy resulted in higher quality of life. We looked to see whether or not it was only those with the most severe sore throats who benefited from tonsillectomy, but we found that patients with more or less severe sore throats at the start all did better with tonsillectomy. Patients who had a tonsillectomy were happy to have undertaken this. Our findings suggest a clear benefit of tonsillectomy using modest additional NHS resources for adults with repeated severe sore throats.

Photobiomodulation in the management of oral mucositis for adult head and neck cancer patients receiving irradiation: the LiTEFORM RCT.

BACKGROUND: Oral mucositis is a debilitating and painful complication of head and neck cancer irradiation that is characterised by inflammation of the mucous membranes, erythema and ulceration. Oral mucositis affects 6000 head and neck cancer patients per year in England and Wales. Current treatments have not proven to be effective. International studies suggest that low-level laser therapy may be an effective treatment. OBJECTIVES: To assess the clinical effectiveness and cost-effectiveness of low-level laser therapy in the management of oral mucositis in head and neck cancer irradiation. To identify barriers to and facilitators of implementing low-level laser therapy in routine care. DESIGN: Placebo-controlled, individually randomised, multicentre Phase III superiority trial, with an internal pilot and health economic and qualitative process evaluations. The participants, outcome assessors and therapists were blinded. SETTING: Nine NHS head and neck cancer sites in England and Wales. PARTICIPANTS: A total of 87 out of 380 participants were recruited who were aged ≥ 18 years and were undergoing head and neck cancer irradiation with ≥ 60 Gy. INTERVENTION: Random allocation (1 : 1 ratio) to either low-level laser therapy or sham low-level laser therapy three times per week for the duration of irradiation. The diode laser had the following specifications: wavelength 660 nm, power output 75 mW, beam area 1.5 cm2, irradiance 50 mW/cm2, exposure time 60 seconds and fluence 3 J/cm2. There were 20-30 spots per session. Sham low-level laser therapy was delivered in an identical manner. MAIN OUTCOME MEASURE: The mean Oral Mucositis Weekly Questionnaire-Head and Neck Cancer score at 6 weeks following the start of irradiation. Higher scores indicate a worse outcome. RESULTS: A total of 231 patients were screened and, of these, 87 were randomised (low-level laser therapy arm, n = 44; sham arm, n = 43). The mean age was 59.4 years (standard deviation 8.8 years) and 69 participants (79%) were male. The mean Oral Mucositis Weekly Questionnaire-Head and Neck Cancer score at 6 weeks was 33.2 (standard deviation 10) in the low-level laser therapy arm and 27.4 (standard deviation 13.8) in the sham arm. LIMITATIONS: The trial lacked statistical power because it did not meet the recruitment target. Staff and patients willingly participated in the trial and worked hard to make the LiTEFORM trial succeed. However, the task of introducing, embedding and sustaining new low-level laser therapy services into a complex care pathway proved challenging. Sites could deliver low-level laser therapy to only a small number of patients at a time. The administration of low-level laser therapy was viewed as straightforward, but also time-consuming and sometimes uncomfortable for both patients and staff, particularly those staff who were not used to working in a patient's mouth. CONCLUSIONS: This trial had a robust design but lacked power to be definitive. Low-level laser therapy is relatively inexpensive. In contrast with previous trials, some patients found low-level laser therapy sessions to be difficult. The duration of low-level laser therapy sessions is, therefore, an important consideration. Clinicians experienced in oral cavity work most readily adapt to delivering low-level laser therapy, although other allied health professionals can be trained. Blinding the clinicians delivering low-level laser therapy is feasible. There are important human resource, real estate and logistical considerations for those setting up low-level laser therapy services. FUTURE WORK: Further well-designed randomised controlled trials investigating low-level laser therapy in head and neck cancer irradiation are needed, with similar powered recruitment targets but addressing the recruitment challenges and logistical findings from this research. TRIAL REGISTRATION: This trial is registered as ISRCTN14224600.

Around 9 out of 10 head and neck cancer patients undergoing treatment experience pain, swelling and sores in their mouth (oral mucositis). This can lead to weight loss, painful ulcers, difficulty talking, eating and drinking, and even hospitalisation. Current care includes helping patients to keep their mouth and teeth clean, encouraging them to have a healthy diet and prescribing mouthwashes, painkillers and mouth-coating gels. However, these treatments give limited help in preventing or treating this condition. The LiTEFORM trial looked at whether or not low-level laser therapy could be used to prevent and treat oral mucositis. Patients were allocated to one of two arms at random: active laser or fake (sham) laser. Neither the patients nor the hospital staff knew which laser was being used. Eighty-seven people joined the study during the time allowed (44 received low-level laser therapy and 43 received sham treatment); however, this was a smaller number than the planned target of 380 people. As a result, no meaningful conclusion can be drawn from the results about whether the therapy is beneficial or cost-effective. People receiving the low-level laser therapy reported slightly more soreness in their mouth than those receiving the sham laser, but this could be down to chance. The number of participants is too small to draw conclusions about whether or not the low-level laser is helpful. Some patients found the laser treatment sessions to be difficult. Setting up a new service delivering laser therapy at the same time as cancer treatments was more complicated than originally anticipated. Problems included the scheduling of appointments, finding suitable rooms and having enough trained staff with time to deliver laser therapy. However, this study has provided us with knowledge on how best to set up a laser therapy service in the NHS as part of the cancer treatment pathway and the costs involved. These findings could help future studies looking into low-level laser therapy for those with head and neck cancer.

Characterization of Problematic Alcohol Use Among Physicians: A Systematic Review.

Importance: Problematic alcohol use in physicians poses a serious concern to physicians' health and their ability to provide care. Understanding the extent and characteristics of physicians with problematic alcohol use will help inform interventions. Objective: To estimate the extent of problematic alcohol use in physicians and how it differs by physician sex, age, medical specialty, and career stage (eg, residency vs practicing physician). Evidence Review: Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020-compliant systematic review, searching Medline, Embase, and PsychInfo from January 2006 to March 2020. Search terms included Medical Subject Headings terms and keywords related to physicians as the population and problematic alcohol use as the primary outcome. The quality of studies was assessed using the Newcastle-Ottawa Scale. We included articles where problematic alcohol use was measured by a validated tool (ie, Alcohol Use Disorders Identification Test [AUDIT], AUDIT Version C [AUDIT-C], or CAGE [Cut down, Annoyed, Guilty, and Eye-opener] questionnaire) in practicing physicians (ie, residents, fellows, or staff physicians). Findings: Thirty-one studies involving 51 680 participants in 17 countries published between January 2006 and March 2020 were included. All study designs were cross-sectional, self-reported surveys. Problematic alcohol use varied widely regardless of measurement method (0 to 34% with AUDIT; 9% to 35% with AUDIT-C; 4% to 22% with CAGE). Reported problematic alcohol use increased over time from 16.3% in 2006 to 2010 to 26.8% in 2017 to 2020. The extent of problematic use by sex was examined in 19 studies, by age in 12 studies, by specialty in 7 studies, and by career stage in 5 studies. Seven of 19 studies (37%) identified that problematic alcohol use was more common in males than females. Based on the wide heterogeneity of methods for included studies, limited conclusions can be made on how problematic alcohol use varies based on physician age, sex, specialty, and career stage. Conclusions and Relevance: Studies about problematic alcohol use in physicians demonstrate a high degree of heterogeneity in terms of methods of measurement, definitions for problematic alcohol use, and cohorts assessed. Most studies are primarily self-reported, precluding the ability to determine the true prevalence among the profession. Few studies provide relevant comparisons to aid in identifying key risk groups for targeted interventions.

The DEVA trial: protocol for a randomised controlled trial of dequalinium chloride versus usual care antibiotics for the treatment of bacterial vaginosis.

BACKGROUND: Bacterial vaginosis (BV) is the most common cause of vaginal discharge in women of reproductive age, and it is estimated that up to a third of women will experience it at some point in their lives. BV produces an offensive vaginal odour and it is associated with serious sequelae. The most frequently prescribed treatment for BV in the UK is 7-day oral metronidazole but recurrences are common following it. Dequalinium chloride (Fluomizin©) is an anti-infective, antiseptic agent administered as a vaginal tablet. Small studies have shown this to be an effective alternative to antibiotics as a BV treatment. This trial aims to investigate whether dequalinium is as effective as current antibiotic treatments for the treatment of BV 1 month after treatment start. METHODS: DEVA is a multi-centre, randomised, open-label, parallel group, non-inferiority trial of dequalinium chloride versus usual care antibiotics for the treatment of BV. Recruitment will take place in 15 GUM clinics in the UK with Leeds Sexual Health also managing remote recruitment via the trial website. Women will be randomised 1:1 to receive dequalinium or usual care antibiotics. The primary outcome is to determine if the proportion of women reporting resolution of BV symptoms 4 weeks after treatment (without the need for additional treatment) is not worse in women treated with dequalinium chloride compared to usual care antibiotics. Questionnaire follow-up will take place 4 and 12 weeks after starting treatment, and remotely recruited patients will also provide a week 4 BV vaginal smear. The sample size is 904. DISCUSSION: This trial will provide high-quality evidence on the use of dequalinium chloride as a BV treatment, which could result in patients reducing the number of antibiotics they take.

Outcomes and experiences of using oral voriconazole with or without concomitant topical agents to treat refractory vulvovaginal yeast infections.

BACKGROUND: We describe 11 cases of refractory vulvovaginal yeast infections (RVVYI) treated using oral voriconazole with or without concomitant topical agents. METHODS: Retrospective case-note review of all women prescribed oral voriconazole to treat RVVYI in five Sexual Health Clinics from Jan 2010-March 2020. Demographic details, clinical features, diagnostic results and treatment outcomes were collected. RESULTS: 11 women with vulvovaginal symptoms for a median of 1 year were treated with voriconazole. RVVYI was diagnosed clinically and confirmed on microscopy and culture with speciation. 10/11 isolates were fluconazole resistant, 1 intermediately sensitive, 10/11 were either fully or intermediately sensitive to voriconazole. All had received prior fluconazole and clotrimazole and 10/11 had used at least 2-weeks of one or more second-line antifungals with non-clearance of the yeast. Oral voriconazole 400 mg BD day-1, then 200 mg BD 13-days was prescribed and 10/11 women completed the course. Concomitant topical treatment was used by 6/11. Liver and renal function were monitored at 0, 7, 14 days. One woman stopped voriconazole after 5-days due to perioral tingling. Other transient side-effects were nausea (n = 2), photosensitivity, muscle aches, hair thinning (all n = 1), peripheral visual disturbance (n = 2). 8/11 experienced both symptom reduction and yeast clearance. Two women had an initial partial response but experienced resolution of symptoms following a second course of voriconazole. CONCLUSIONS: Our observational data adds to the limited evidence to support voriconazole treatment for RVVYI. A 2-week course of voriconazole was tolerated and completed by 10/11 women. Eight women, five using concomitant topical agents, achieved mycological cure.

How do patients make decisions in the context of a multidisciplinary team: an ethnographic study of four head and neck cancer centres in the north of England.

OBJECTIVES: To describe how patients are engaged with cancer decisions in the context of multidisciplinary team (MDT) and how MDT recommendations are operationalised in the context of a shared decision. DESIGN: Ethnographic qualitative study. SETTING: Four head and neck cancer centres in the north of England. PARTICIPANTS: Patients with a diagnosis of new or recurrent head and neck cancer; non-participant observation of 35 MDT meetings and 37 MDT clinics, informal interviews, and formal, semistructured interviews with 20 patients and 9 MDT staff members. METHODS: Ethnographic methods including non-participant observation of MDT meetings and clinic appointments, informal interviews, field notes and formal semistructured interviews with patients and MDT members. RESULTS: MDT discussions often conclude with a firm recommendation for treatment. When delivered to a patient in clinic, this recommendation is often accepted by the patient, but this response may result from the disempowered position in which they find themselves. While patient behaviour may thus appear to endorse clinicians' views that a paternalistic approach is desired by patients (creating a 'cycle of paternalism'), the rigidity of the MDT treatment recommendation can act as a barrier to discussion of options and the exploration of patient values. CONCLUSIONS: The current model of MDT decision-making does not support shared decision-making and may actively undermine it. A model should be developed whereby the individual patient perspective has more input into MDT discussions, and where decisions are made on potential treatment options rather than providing a single recommendation for discussion with the patient. Deeper consideration should be given to how the MDT incorporates the patient perspective and/or delivers its discussion of options to the patient. In order to achieve these objectives, a new model of MDT working is required.

British Association for Sexual Health and HIV (BASHH) United Kingdom national guideline on the management of Trichomonas vaginalis 2021.

The main objective of this guideline is to assist practitioners in managing individuals diagnosed with Trichomonas vaginalis (TV). It offers recommendations on the diagnostic tests, treatment regimens and health promotion principles needed for the effective management of TV. It covers the management of the initial presentation, as well as how to prevent transmission and future re-infection. It is aimed primarily at people aged 16 years or older presenting to health care professionals, working in departments offering specialist care in sexually transmitted infection (STI) management within the United Kingdom. However, the principles of the recommendations are applicable across all levels of STI care providers (N.B. non-specialist services may need to develop, where appropriate, local care pathways).

The Physical Activity Levels and Sitting Time of Adults Living With Atrial Fibrillation: The CHAMPLAIN-AF Study.

Background: The primary goal of this study was to determine the time spent completing moderate-to-vigorous intensity physical activity (MVPA) among adults with atrial fibrillation (AF). Secondary aims examined MVPA and sitting time (ST) by AF subtypes (ie, paroxysmal, persistent, long-standing persistent, and permanent) and associations between MVPA or ST and knowledge, task self-efficacy, and outcome expectations. Methods: An observational study was conducted in the Champlain region of Ontario, Canada. AF patients completed a survey to determine MVPA and ST using the Short-Form International Physical Activity Questionnaire. Results: A total of 619 patients (66% male; median age 65 years [95% CI 64-67 years]) completed the survey. Median MVPA and ST were 100 (60-120) min/wk and 6 (5-6) h/d; 56% of patients were not meeting the Canadian 24H Movement Guidelines. Most patients (54%) did not know/were unsure of the MVPA recommendations, yet 72% thought physical activity should be part of AF management. Positive correlations were found between higher MVPA levels and the following: (i) speaking to a healthcare professional about engaging in physical activity for managing AF (ρ = 0.108, P = 0.017); (ii) greater confidence regarding ability to perform physical activity and muscle-strengthening exercise (ρ = 0.421, P < 0.01); and (iii) patient agreement that AF would be better managed if they were active (ρ = 0.205, P < 0.01). Conclusions: Many AF patients do not meet the MVPA recommendations, which may be due to lack of physical activity knowledge. Exercise professionals may help educate patients on the benefits of physical activity, improve task-self efficacy, and integrate MVPA into patient lifestyles.

Introduction: Le principal objectif de la présente étude était de déterminer le temps consacré à faire de l'activité physique modérée à vigoureuse (APMV) chez les adultes atteints de fibrillation auriculaire (FA). Les objectifs secondaires visaient à examiner l'APMV et le temps en position assise (TA) selon les sous-types de FA (c.-à-d. paroxystique, persistante, persistante de longue durée et permanente) et les associations entre l'APMV ou le TA et les connaissances, le sentiment d'auto-efficacité et les attentes de résultats. Méthodes: Nous avons réalisé une étude observationnelle dans la région de Champlain, en Ontario, au Canada. Les patients atteints de FA ont rempli une enquête pour déterminer l'APMV et le TA à l'aide du questionnaire court International Physical Activity Questionnaire (IPAQ). Résultats: Un total de 619 patients (66 % d'hommes; âge médian de 65 ans [IC à 95 % 64-67 ans]) a rempli l'enquête. L'APMV et le TPA médians étaient de 100 (60-120) min/sem et de 6 (5-6) h/j; 56 % des patients ne répondaient pas aux Directives canadiennes en matière de mouvement sur 24 heures. La plupart des patients (54 %) ne connaissaient pas les recommandations d'APMV ou n'étaient pas certains de les connaître, mais 72 % pensaient que l'activité physique devrait faire partie de la prise en charge de la FA. Nous avons observé des corrélations positives entre les degrés plus élevés d'APMV et ce qui suit : (i) le fait de parler à un professionnel de la santé de la pratique de l'activité physique pour prendre en charge la FA (ρ = 0,108, P = 0,017); (ii) la confiance accrue quant à la capacité de faire de l'activité physique et les exercices de renforcement musculaire (ρ = 0,421, P < 0,01); (iii) l'accord du patient sur le fait que la pratique de l'activité physique contribuerait à une meilleure prise en charge de la FA (ρ = 0,205, P < 0,01). Conclusions: Plusieurs patients atteints de FA ne répondaient pas aux recommandations d'APMV, possiblement en raison du manque de connaissances concernant l'activité physique. Les professionnels de l'activité physique peuvent contribuer à l'éducation des patients afin de leur faire connaître les avantages de l'activité physique, améliorer leur auto-efficacité et intégrer l'APMV à leur mode de vie.

'Persistent throat symptoms' versus 'laryngopharyngeal reflux': a cross-sectional study refining the clinical condition.

OBJECTIVE: Many patients are assessed for chronic symptoms including: dysphonia, 'globus', throat clearing, postnasal secretions and cough; commonly grouped together and attributed to 'laryngopharyngeal reflux'. This study aimed to explore a clinical trial's baseline dataset for patterns of presenting symptoms, which might provide a more rational basis for treatment. DESIGN: Baseline data were analysed for participants entering the Trial Of Proton-Pump Inhibitors in Throat Symptoms: age, body mass index, Reflux Symptom Index, Comprehensive Reflux Symptom Score, Laryngopharyngeal Reflux-Health-related Quality of Life questionnaire and Reflux Finding Score (RFS-endoscopic examination). The relationships between the questionnaires and demographic factors were assessed. Exploratory factor analysis (EFA) was conducted on individual symptom items in the combined questionnaires. The EFA factors were applied to a Cluster Analysis of participants, to explore the presence of identifiable patient. RESULTS: Throat clearing and globus were the highest ranked scores in the 344 participants. Increasing age was inversely associated with symptom severity (p<0.01). There was no relationship between the RFS and any of the three questionnaires. EFA resulted in a seven-factor model with clinically meaningful labels: voice, cough, gastrointestinal symptoms, airway symptoms and dysphagia, throat clearing, lump in throat, and life events. Cluster analysis failed to demonstrate any clinically meaningful clusters of patients. CONCLUSION: This study offers a framework for future research and demonstrates that individual symptoms cannot be used to group patients. The analysis supports the use of a broad 'umbrella' term such as persistent throat symptoms. TRIAL REGISTRATION NUMBER: ISRCTN38578686.

The expense of sending cerebrospinal fluid for analysis on all lumbar punctures in pediatric acute lymphoblastic leukemia patients.

BACKGROUND: Central nervous system (CNS) relapse in pediatric acute lymphoblastic leukemia (ALL) patients is uncommon. The cerebrospinal fluid (CSF) of patients with ALL is routinely sampled at each intrathecal chemotherapy treatment to screen for CNS relapse. The analysis of CSF is both time consuming and resource intensive and must be completed approximately 20 times per patient throughout treatment. Our objective was to examine the expense of routine screening on all CSF samples for CNS relapse in ALL patients, and to identify if CNS relapse can be detected clinically. METHODS: We identified all patients diagnosed with ALL at the Children's Hospital of Eastern Ontario (CHEO) between January 2001 and June 2021. We collected the total number of CSF samples in these patients and the number of CSF samples positive for CNS relapse. An in-depth chart review on the patients who relapsed in the CNS was completed to identify symptoms at relapse. RESULTS: Over the study period, 351 patients were diagnosed with ALL and underwent a total of 6515 lumbar punctures (LPs), each of which examined the CSF. The cost of CSF sample analysis is $14.32 (Canadian dollars [CDN]); thus, the total cost for the study sample was $93,294.80 (CDN). There were 14 CNS relapses and although symptoms including headache, vomiting, and fatigue were common, two patients were asymptomatic at relapse. CONCLUSIONS: Given the marginal cost of routine CSF screening and the lack of specific and sensitive symptoms for CNS relapse, we conclude that the routine practice of sending all CSF samples for analysis of CNS relapse in ALL patients is relatively inexpensive and beneficial.
