Clinical value of Alzheimer's disease biomarker testing.

INTRODUCTION: In the Investigating the Impact of Alzheimer's Disease Diagnostics in British Columbia (IMPACT-AD BC) study, we aimed to understand how Alzheimer's disease (AD) cerebrospinal fluid (CSF) biomarker testing-used in medical care-impacted medical decision-making (medical utility), personal decision-making (personal utility), and health system economics. METHODS: The study was designed as an observational, longitudinal cohort study. A total of 149 patients were enrolled between February 2019 and July 2021. Patients referred to memory clinics were approached to participate if their dementia specialist ordered AD CSF biomarker testing as part of their routine medical care, and the clinical scenario met the appropriate use criteria for lumbar puncture and AD CSF biomarker testing. For the medical utility pillar, detailed clinical management plans were collected via physician questionnaires pre- and post-biomarker disclosure. RESULTS: Patients with completed management questionnaires (n = 142) had a median age of 64 (interquartile range: 59-69) years, 48% were female, and 60% had CSF biomarker profiles on the AD continuum. Clinical management changed in 89.4% of cases. AD biomarker testing was associated with decreased need for other diagnostic procedures, including brain imaging (-52.0%) and detailed neuropsychological assessments (-63.2%), increased referrals and counseling (57.0%), and guided AD-related drug prescriptions (+88.4% and -50.0% in biomarker-positive and -negative cases, respectively). DISCUSSION: AD biomarker testing was associated with significant and positive changes in clinical management, including decreased health care resource use, therapy optimization, and increased patient and family member counseling. While certain changes in management were linked to the AD biomarker profile (e.g., referral to clinical trials), the majority of changes were independent of baseline clinical presentation and level of cognitive impairment, demonstrating a broad value for AD biomarker testing in individuals meeting the appropriate use criteria for testing.

[Increased report completeness and satisfaction with structured neurotological reporting in the interdisciplinary assessment of vertigo]. / Erhöhte Befundvollständigkeit und gesteigerte Zuweiserzufriedenheit bei strukturierter neurootologischer Befunderhebung in der interdisziplinären Schwindelabklärung.

BACKGROUND: Results of neurotological function diagnostics in the context of interdisciplinary vertigo assessment are usually formulated as free-text reports (FTR). These are often subject to high variability, which may lead to loss of information. The aim of the present study was to evaluate the completeness of structured reports (SR) and referrer satisfaction in the neurotological assessment of vertigo. MATERIALS AND METHODS: Neurotological function diagnostics performed as referrals (n = 88) were evaluated retrospectively. On the basis of the available raw data, SRs corresponding to FTRs from clinical routine were created by means of a specific SR template for neurotological function diagnostics. FTRs and SRs were evaluated for completeness and referring physician satisfaction (n = 8) using a visual analog scale (VAS) questionnaire. RESULTS: Compared to FTRs, SRs showed significantly increased overall completeness (73.7% vs. 51.7%, p < 0.001), especially in terms of patient history (92.5% vs. 66.7%, p < 0.001), description of previous findings (87.5% vs. 38%, p < 0.001), and neurotological (33.5% vs. 26.7%, p < 0.001) and audiometric function diagnostics (58% vs. 32.3%, p < 0.001). In addition, SR showed significantly increased referring physician satisfaction (VAS 8.8 vs. 4.9, p < 0.001). CONCLUSION: Neurotological SRs enable a significantly increased report completeness with higher referrer satisfaction in the context of interdisciplinary assessment of vertigo. Furthermore, SRs are particularly suitable for scientific data analysis, especially in the context of big data analyses.

The long-term impact of vaginal surgical mesh devices on pain clinic and psychological service referrals, anti-inflammatory testing and pelvic scans in UK primary care: A cohort study with the Clinical Practice Research Datalink.

OBJECTIVE: To examine long-term complications in women with stress urinary incontinence (SUI) and pelvic organ prolapse (POP), with and without surgical mesh implants. DESIGN: Longitudinal open cohort study from 1 April 2006 (or 1 April 2012) to 30 November 2018. SETTING: The Clinical Practice Research Datalink (CPRD) Gold database, which is linked to Hospital Episodes Statistics (HES) inpatient data, the HES Diagnostic Imaging Dataset (DID), Office for National Statistics mortality data and Index of Multiple Deprivation socio-economic status data. SAMPLE: Women aged ≥18 years with a diagnostic SUI/POP Read code. METHODS: Rates are estimated using negative binomial regression. MAIN OUTCOME MEASURES: Rates of referrals for: psychological and pain services; urinalysis, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) testing; and pelvic ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) scans. RESULTS: A cohort of 220 544 women were eligible for inclusion; 74% (n = 162 687) had SUI, 37% (n = 82 123) had POP and 11% (n = 24 266) had both. Rates of psychological referrals and CT scans were lower in women with SUI mesh surgery, but this was offset by higher rates of CRP testing in women with SUI or POP mesh, MRI scans in women with SUI mesh, and urinalysis testing and referrals to pain clinics for women with POP mesh. CONCLUSIONS: Our results suggest a higher burden of morbidity in women with SUI/POP mesh surgery, and that these women may require ongoing follow-up in the primary care setting.

Pediatric growth hormone deficiency: Understanding the patient and caregiver perspectives.

Childhood growth hormone deficiency (GHD) is a rare disorder associated with significant burden on both patients and caregivers. Although previous reports have detailed aspects of the burden experienced by patients and their caregivers, there is a paucity of first-hand information on the patient and caregiver journeys from their respective voices. To address this need, an advisory board meeting was conducted on September 30, 2022, with 4 pediatric patients with GHD and their caregivers to discuss their experiences prior to GHD diagnosis, during the diagnostic process, and during ongoing treatment with recombinant growth hormone. Feedback from patients and caregivers was reviewed by pediatric endocrinologists, who provided their own perspectives on the patient and caregiver journeys based on the information reported. Despite the small sample size, important insights were obtained: patients and caregivers reported remarkable growth benefits achieved with treatment, which provided strong motivation to remain adherent to daily injection regimens. Patient and caregiver accounts reflected wide variability between families in time from suspicion to diagnosis and in treatment challenges faced, ranging from practical issues such as handling and administration of medication to broader concerns about treatment access and continuity, as well as key knowledge gaps among patients, caregivers, and clinicians. Recommendations are provided to enhance the patient and caregiver journeys, including increasing development and availability of educational materials, providing opportunities for patient advocacy by clinicians and health care providers, and encouraging institutional improvements to ensure that patients continue to receive uninterrupted treatment during their critical period of growth.

Use of Video in Telephone Triage in Out-of-Hours Primary Care: Register-Based Study.

Background: Out-of-hours primary care (OOH-PC) is challenging due to high workloads, workforce shortages, and long waiting and transportation times for patients. Use of video enables triage professionals to visually assess patients, potentially ending more contacts in a telephone triage contact instead of referring patients to more resource-demanding clinic consultations or home visits. Thus, video use may help reduce use of health care resources in OOH-PC. Objective: This study aimed to investigate video use in telephone triage contacts to OOH-PC in Denmark by studying rate of use and potential associations between video use and patient- and contact-related characteristics and between video use and triage outcomes and follow-up contacts. We hypothesized that video use could serve to reduce use of health care resources in OOH-PC. Methods: This register-based study included all telephone triage contacts to OOH-PC in 4 of the 5 Danish regions from March 15, 2020, to December 1, 2021. We linked data from the OOH-PC electronic registration systems to national registers and identified telephone triage contacts with video use (video contact) and without video use (telephone contact). Calculating crude incidence rate ratios and adjusted incidence rate ratios (aIRRs), we investigated the association between patient- and contact-related characteristics and video contacts and measured the frequency of different triage outcomes and follow-up contacts after video contact compared to telephone contact. Results: Of 2,900,566 identified telephone triage contacts to OOH-PC, 9.5% (n=275,203) were conducted as video contacts. The frequency of video contact was unevenly distributed across patient- and contact-related characteristics; it was used more often for employed young patients without comorbidities who contacted OOH-PC more than 4 hours before the opening hours of daytime general practice. Compared to telephone contacts, notably more video contacts ended with advice and self-care (aIRR 1.21, 95% CI 1.21-1.21) and no follow-up contact (aIRR 1.08, 95% CI 1.08-1.09). Conclusions: This study supports our hypothesis that video contacts could reduce use of health care resources in OOH-PC. Video use lowered the frequency of referrals to a clinic consultation or a home visit and also lowered the frequency of follow-up contacts. However, the results could be biased due to confounding by indication, reflecting that triage GPs use video for a specific set of reasons for encounters.

Referral patterns and outcomes of children who failed Modified Checklist for Autism in Toddlers screening during routine health screening at maternal and child health clinics in the northeast district of Penang: A retrospective cohort study.

Introduction: Autism spectrum disorder (ASD) is a developmental disability that causes significant social, communication and behavioural challenges. The Modified Checklist for Autism in Toddlers (M-CHAT) is a parent-administered screening questionnaire for ASD used at 18 and 36 months of age. This study aimed to determine the outcomes of children who failed M-CHAT screening during routine health screening at maternal and child health clinics in northeast district, Penang and the prevalence of ASD among those with a final diagnosis. Methods: This retrospective cohort study was conducted at 12 maternal and child health clinics. All children who failed M-CHAT screening at 18 and 36 months from January 2017 to December 2021 and received a final diagnosis before 31 March 2022 were recruited. All information required was recorded in a data collection form and analysed using SPSS. Multiple logistic regression was performed to assess the association between the factors and ASD status. Results: Eighty-two children failed M-CHAT screening. Fifty children did not receive a final diagnosis. Among 32 children who received a final diagnosis, 25 were diagnosed with ASD (78.1%). Among the children who underwent M-CHAT screening, the odds of having ASD increased by a factor of 1.2 for every 1-unit increase in age at final diagnosis. Conclusion: In northeast district, Penang, more than half of children who fail M-CHAT screening have no final diagnosis. The specificity of the M-CHAT is 78.1% among children with a final diagnosis of ASD. The age at final diagnosis is positively associated with the diagnosis of ASD.

Challenges of Using Telemedicine in Hospital Specialty Consultations during the COVID-19 Pandemic in Portugal According to a Panel of Experts.

INTRODUCTION: The COVID-19 pandemic has accelerated the adoption of telemedicine as a means of reducing face-to-face contact and protecting professionals and patients. In Portugal, the number of hospital telemedicine consultations has significantly increased. However, the rapid implementation of telemedicine has also led to disparities in access to these services, resulting in inequalities in healthcare delivery. The aim of this study was to identify the main challenges to accessing hospital medical specialty consultations through telemedicine in Portugal during the COVID-19 pandemic. Additionally, this study aimed to establish a consensus on possible solutions for the challenges which were identified. METHODS: This study used the nominal group technique, which involved a panel of 10 experts. The panel generated a total of 71 ideas, which were then categorized into three groups: A) challenges relating to patients, which impact access to hospital-based medical specialty consultations through telemedicine; B) challenges relating to professionals, institutions and health systems, which impact access to hospital medical specialty consultations through telemedicine; C) recommendations to overcome the challenges faced in adopting telemedicine solutions. Each of the ideas was assessed, scored and ranked based on its relevance considering the study objectives. RESULTS: This study identified several significant challenges that impacted the adoption of telemedicine in Portugal during the COVID-19 pandemic. The challenges that related to patients (A) that were deemed the most relevant were low digital literacy, lack of information about telemedicine processes, low familiarity with technologies and distrust about the quality of services; the challenges that impacted healthcare professionals, institutions, and health systems (B) and were deemed the most relevant were the lack of integration of telemedicine in the patient's journey, low motivation to adopt telemedicine solutions, poor interoperability between systems, and the absence of the necessary technological equipment. The most relevant recommendations (C) included investing in healthcare institutions, developing clear guidelines for the safety and quality of telemedicine practices, and incorporating telemedicine into the curricula of health professions. CONCLUSION: This study identified several challenges that impacted the adoption and implementation of telemedicine services for hospital care in Portugal during the pandemic period. These challenges were related to digital health literacy, technological and operational conditions, and reluctance in technological adoption. To overcome these challenges, training programs for healthcare professionals and patients may be necessary, along with investment in technological infrastructures, interoperability between systems, effective communication strategies and the strengthening of specific regulations.

A novel referral strategy to enhance the enrollment of patients with heart failure in cardiac rehabilitation: A feasibility study.

Background and Aims: Rehabilitation targeting patients with cardiac conditions are evident and acknowledged in clinical guidelines. However, participation rates remain suboptimal, with only 50% of all patients with cardiac conditions participating in these programs across Europe. Considering the well-documented effects of rehabilitation, increasing the referral rate to cardiac rehabilitation would be desirable. This study aimed to evaluate the feasibility of a novel referral strategy that could potentially enhance enrollment in cardiac rehabilitation for patients with heart failure. Methods: This prospective feasibility study incorporating both quantitative and qualitative methods was conducted in an outpatient heart failure clinic and a municipal health care center. 106 patients with heart failure were referred to the heart failure clinic from September 2021 through July 2022. A 15-20 min face-to-face physiotherapy consultation was incorporated into usual care, evaluating patients' habitual and actual level of functioning, disability, and physical activity and assessing their potential need and motivation for cardiac rehabilitation. Three predefined quantitative feasibility outcomes: reach, referral rate, and data completeness were assessed. Additionally, semi-structured interviews explored acceptability among patients and health care professionals at the municipal health care center and the hospital. Finally, the potential effect was assessed based on the enrollment rate. Results: Physiotherapy consultations were offered to 86% of eligible patients; of these, 52% were referred to cardiac rehabilitation. Ninety-one percent data completeness was achieved. The intervention was well-accepted by patients and health care professionals. The enrollment rate reached 79%. Conclusion: The novel referral strategy proved feasible concerning reach and data completeness, although the referral rate suggested that further refinements are required before a full-scale trial. The novel referral strategy was well-accepted, and enrollment rate approached an acceptable level.

Appropriateness of the Emergency Referrals Made by Primary Care Clinicians: A cross-sectional review of referral notes.

Objectives: This study aimed to evaluate the appropriateness of the emergency referrals made by primary care clinicians and determine the factors contributing to inappropriate referrals. Methods: This cross-sectional study utilises referral notes review between October 2019 and March 2020. Patients referred to Khawla Hospital's emergency department by a primary care clinician in Muscat Governorate were randomly selected; their referral notes were reviewed by five family physicians. The appropriateness of the referrals was evaluated according to the primary care referral protocol. Any referral that deviated from the protocol was classified as inappropriate. The prevalence and characteristics of inappropriate referrals were identified, and the factors contributing to inappropriate referral were determined using multivariable logistic regression. Results: In total, 591 referrals were reviewed; 354 (59.9%) of them were classified as inappropriate due to inadequate medical notes (291, 82.2%), lack of provisional diagnosis (176, 49.7%), misdirected to a non-concerned emergency (30, 8.4%) or misclassification of urgency (107 [30.2%] were classified as urgent and 45 [12.7%] as routine). After adjusting for multiple variables, insufficient clinical notes, unavailability of referral guidelines and lack of expertise were found to be strong determinants of inappropriate referral, with an odds ratio of 62.52 (95% confidence interval [CI]: 32.04-121.96), 2.88 (95% CI: 1.40-5.92) and 9.37 (95% CI: 4.09-21.43), respectively. Conclusion: While most of the referrals required emergency management, the majority were inappropriate, mainly due to insufficient clinical documentation. Inadequate clinical notes and lack of national guidelines and expertise were found to be strong predictors of inappropriate emergency referrals.

Increasing primary care capacity and referral efficiency: A case study of a telehealth centre eConsult service in Brazil.

INTRODUCTION: eConsults are asynchronous digital communications for primary care professionals to seek timely specialist advice. Potential benefits include increased primary healthcare capacity and referral efficiency. Santa Catarina Telehealth Centre in Brazil has offered eConsults for an increasing number of specialties since 2008. This study described the characteristics of this service, including referral efficiency, sustainability, and satisfaction. METHODS: Retrospective longitudinal analysis of eConsults activity data from 2015 to 2022 with three domains of the Model for Assessment of Telemedicine Applications used to structure the analysis. RESULTS: Characteristics of the application: The total number of eConsults performed in 2015 was 4764, reaching 41,178 in 2022. While 30.3% of eConsults were synchronous in 2015, only asynchronous communication remained from 2021. Clinical effectiveness: eConsults requested to refer patients to specialist care resulting in primary care management remaining above 30% of the total for all specialties from 2019 to 2022, with hematology having the highest percentage (>52%). Organizational aspects: Established workflows with local specialists responding to eConsults (cardiology, endocrinology, hematology and orthopaedics) kept a constant or increasing number of eConsults and maintained the proportion of primary care management from 2019 to 2022, once recovered from COVID-19 and funding restrictions-related reductions. Over 90% of primary care professionals are either satisfied or very satisfied with the eConsult service. CONCLUSION: Over 8 years, 223,734 consultations were conducted, with high satisfaction, demonstrating the substantial potential for increased primary care-sensitive conditions management. Hiring local specialists, fostering integrated care, and enabling sustainable workflows are key to eConsults' success.

Vulval dermatoses: A review of referrals to dermatology.

We undertook a retrospective observational review of patients referred to a tertiary dermatology department with vulval complaints over 12 months. The most common provisional diagnoses made by the referrer and final dermatology diagnoses were lichen sclerosus (54% and 38%), dermatitis (12.7% and 16.5%) and psoriasis (5.1% and 6.3%). Referrers may benefit from further education about skin diseases of the vulva, topical steroids for vulval complaints and the importance of clinical photography.

Addressing Perinatal Substance Use: A Triad Approach Led by the Colorado Perinatal Care Quality Collaborative.

Unintentional overdose is a leading driver of maternal death in Colorado. The high volume of maternal deaths from preventable causes lends questions to failures in our clinical and community-based care for pregnant and postpartum people. The Colorado Maternal Mortality Review Committee identified 3 main contributors including stigma in the community and health care system, fragmentation of the health care system, and the need for more clinician training. The Colorado Perinatal Care Quality Collaborative led a 3-pronged intervention to address these challenges and improve perinatal care. The first intervention, the Colorado Alliance for Innovation on Maternal Health Substance Use Disorder quality improvement initiative, partnered with birthing hospitals statewide to institute universal screening and timely referral for individuals at risk of substance use disorder (SUD) and perinatal mood and anxiety disorders. The second intervention, the Improve Perinatal Access, Coordination, and Treatment for Behavioral Health initiative, established a perinatal support network within communities. This program assists individuals with SUD, perinatal mood and anxiety disorders, or social needs to navigate the perinatal period. The third intervention, the Colorado Maternal Overdose Matters Plus program, has enhanced in-hospital access to pharmacotherapy for pregnant and postpartum individuals with SUD through training and technical support. These collaborative initiatives aim to minimize barriers to care by integrating inpatient screening, treatment referrals, pharmacotherapy access, and community care support to mitigate maternal mortality in Colorado.

Effectiveness and diagnostic accuracy of teledermatology for the assessment of skin conditions.

BACKGROUND: Teledermatology provides a platform for swift specialist advice without the potential need for face-to-face review. Our objectives were to investigate the effectiveness, accuracy and diagnostic concordance of the platform with regard to the remote management of skin conditions. METHODS: We undertook a single-centre, retrospective chart review over a 1-year period, comprising a total of 1703 teledermatology referrals. Two physicians independently assessed the diagnostic concordance between telederm diagnosis (TD), in-person diagnosis (ID) and histopathological diagnosis (HD). RESULTS: There were a total of 1703 TD referrals, of which 341 were rejected, leaving 1362 referrals for evaluation. Sixty-five per cent of these referrals were managed remotely and discharged with advice, although 4.6% of these were later re-referred for an in-person review. A total of 20% of referrals were rejected, of which the majority was due to a lack of appropriate imaging. The total concordance of TD compared to ID was 76.4%. When comparing the TD and ID/HD, we obtained a Kappa value of 0.636 indicating substantial agreement. In terms of accuracy, there were 49 biopsy-proven skin cancers picked up by the service in this cohort of data. Of these, 61.2% were given an accurate diagnosis on first impression via teledermatology, 14.3% were given a different diagnosis but correctly categorised as skin cancer and 24.5% could not be assessed; however, they were triaged and escalated based upon clinical suspicion. CONCLUSION: Our study demonstrates that teledermatology is an effective platform in terms of diagnosis and remote management, with adequate diagnostic accuracy and concordance to in-person diagnosis.

Evaluating the Appropriateness of ENT Emergency Clinic Referrals to Enhance the Quality of Healthcare Provision in the National Health Service (NHS).

Background Ear, Nose, and Throat (ENT) services in the National Health Service (NHS) face escalating pressure, exacerbated by the COVID-19 pandemic, resulting in prolonged waiting times and increased referrals. Understanding the factors driving pressure on ENT services is crucial for enhancing patient care and resource allocation. Methods A retrospective single-centre cohort study was conducted at Queen's Medical Centre, Nottingham, UK, over five weeks. A total of 156 referrals to the ENT Emergency Clinic (E-Clinic) were analyzed, assessing the appropriateness of referrals and healthcare professionals' involvement in reviewing cases. Results The analysis revealed 28 distinct case categories, with certain conditions being predominant in specific reviews (e.g., otitis externa, nasal fractures, epistaxis). Notably, 21.8% of cases were deemed unsuitable or inappropriate for E-Clinic assessment. Strategic restructuring was suggested, distributing cases among healthcare professionals based on expertise and complexity. Discussion The findings underscore the need for a refined referral process and appropriate allocation of cases, emphasising the importance of nurse-led reviews for certain conditions and the necessity for senior review in complex cases. Improving the primary-secondary care interface and educating healthcare professionals on appropriate referrals are crucial for refining the system. Conclusion Optimising the quality of referrals and allocation of cases within ENT E-Clinics can alleviate workload pressures and enhance patient care. Strategic distribution of cases based on expertise and complexity, alongside refined referral processes, can significantly improve clinic efficiency and patient outcomes in the NHS.

Adherence to Emergency Department Referral Criteria in a Direct-to-Consumer Telemedicine Center.

Background: The safety of direct-to-consumer telemedicine (TM) is closely related to red flag detection and correct referrals. The adherence to referral criteria from current guidelines is not well quantified. Objective: To analyze the emergency department (ED) referral rate and adherence to referral guidelines in TM encounters of acutely ill patients calling a center that adopts stewardship protocols. Methods: This is a retrospective observational unicentric study, between March 2020 and March 2022, with patients who spontaneously sought direct-to-consumer urgent virtual medical assistance. A video-based teleconsultation was provided immediately after connection. Physicians managed situations according to their clinical judgment. Current guidelines, containing specific guidance for referral if red flags were identified, were available for consultation. Physicians' semiannual performance feedback was carried out. We analyzed the patterns for referral to immediate face-to-face medical evaluation and the agreement degree with the institutional guidelines. Results: A total of 232,197 patients were available, and 14,051 (6.05%) patients were referred to ED. A total of 8,829 (68.4%) referrals were based in specific guidelines according to the International Classification of Diseases hypothesis, and 8,708 (98.6%) were justified according to guidelines. Diarrhea had the highest guidelines' adherence to referral (97.6%), followed by COVID-19 (90%), headache (84.2%), and conjunctivitis (78.8%). Policies did not support 5,222 (31.6%) referrals, though 5,100 (97.6%) of these were justified according to the doctor's clinical judgment. Conclusion: TM doctors' assessment of acutely ill patients has high rates of adherence to guidelines regarding referral. Stewardship protocol adoption provides high rates of red flag description, even in the referral of nonpolicy diseases.

COPD patient profiles in primary care. Referral criteria.

COPD is a disease with a high prevalence that diminishes the quality of life of many patients. Despite this, there are still high rates of under-diagnosis in Spain, partly due to a lack of recognition of the pathology by patients. In this context, the role played by primary care teams becomes fundamental, as they are one of the first lines of entry into the health system. In this paper we explain the different COPD profiles that may be present, and update the tools for diagnosis and treatment, which, together with an attitude of active suspicion of the disease, can help in the correct management of patients, whether they are undiagnosed or have subsequent complications.

How appropriate are referral letters written by school principals to a learning disability clinic? A retrospective audit.

This retrospective study analyzed the quality of 1069 referral letters written by school principals to our learning disability clinic. Utilizing a self-devised checklist having four domains (with 26 items), the audit revealed that in only nine (34.6%) items, the necessary information was available in >90% of referral letters.

Retrospective analysis of referrals for hypoxic challenge testing in children born preterm.

INTRODUCTION: Children with a history of bronchopulmonary dysplasia (BPD) may be at risk of hypoxaemia at altitude, such as during air travel. We have performed preflight hypoxic challenge testing (HCT) since 2006, incorporating British Thoracic Society (BTS) guidance since 2011, to determine which children may require oxygen during air travel. AIMS: We aimed to compare the outcome of HCTs in children with a history of BPD who met the 2011 BTS criteria and those who did not and, in addition to this, to interrogate the data for factors that may predict the outcome of HCT in this population. METHODS: We performed a retrospective analysis of data from HCTs of children with a history of BPD referred 2006-2020. Cases were excluded if the patient had a respiratory comorbidity, was still on oxygen therapy, if the test was a repeat or if the clinical record was incomplete. Descriptive and univariate analysis of the data was performed, and a binary logistic regression model was fitted. RESULTS: There were 79 HCTs, of which 24/79 (30%) did not meet BTS 2011 guidelines referral criteria. The analysis showed a greater proportion of desaturation in the group that did not meet criteria: 46% vs 27% (no statistical significance). Baseline oxygen saturations were higher in those who did not require oxygen during HCT and this variable was significant when adjusted for confounders. CONCLUSIONS: This study found that the current criteria for referral for preflight testing may incorrectly identify those most at risk and highlights the need for further investigation to ensure those most at risk are being assessed prior to air travel.

Exploring diagnostic strategies for memory complaints in older adults: A retrospective general practice database study.

OBJECTIVES: For older people who worry about their memory, their general practitioner (GP) is often the first healthcare professional they turn to. This study aims to increase knowledge of GPs' daily practice on diagnostic strategies for patients who present themselves with memory complaints and/or worries about dementia for the first time in general practice and to explore associations of patients' characteristics with these strategies. METHOD: Retrospective observational study using electronic patient records from patients presenting with memory complaints between 2012 and 2019. The patient records are derived from a Dutch primary care registration network. The decision on diagnostic strategy was extracted and categorized as (1) wait and see, (2) diagnostic testing in primary care, or (3) referral. Patient characteristics (gender, age, general practice, level of comorbidities, chronic polypharmacy, and the number of consultations on memory complaints), fear of developing dementia, and information on why the first consultation on memory complaints was scheduled were extracted. RESULTS: A total of 228 patients were included. Most patients were cared for within primary care, either for further primary care diagnostics (56.1%) or because a wait-and-see strategy was pursued (14.9%). One-third (28.9%) of patients were referred. Differences between diagnostic strategies in patient characteristics, fear of developing dementia, or reason for first consultation between these diagnostic strategies were not found, nor were these variables predictive of referral. CONCLUSION: Most Dutch patients with memory complaints and/or worries about dementia who seek help from their GP for the first time are cared for in the primary care setting for the following 6 months. The lack of association between included patient characteristics and diagnostic strategies highlights the complexity of the decision-making process on diagnostic testing for dementia in general practice.

Impact of point-of-care clinical decision support on referrer behavior, imaging volume, patient radiation dose exposure, and sustainability.

OBJECTIVES: When referring patients to radiology, it is important that the most appropriate test is chosen to avoid inappropriate imaging that may lead to delayed diagnosis, unnecessary radiation dose, worse patient outcome, and poor patient experience. The current radiology appropriateness guidance standard at our institution is via access to a standalone web-based clinical decision support tool (CDST). A point-of-care (POC) CDST that incorporates guidance directly into the physician workflow was implemented within a subset of head and neck cancer specialist referrers. The purpose of this audit was to evaluate the imaging pathway, pre- and post-implementation to assess changes in referral behavior. METHODS: CT and MRI neck data were collected retrospectively to examine the relationship between imaging referrals pre- and post-POC CDST implementation. Effective radiation dose and estimated carbon emissions were also compared. RESULTS: There was an overall reduction in absolute advanced imaging volume by 8.2%, and a reduction in duplicate CT and MRI imaging by 61%, p < 0.0001. There was also a shift in ordering behavior in favor of MRI (OR [95% CI] = 1.50 [1.02-2.22], p = 0.049). These changes resulted in an effective radiation dose reduction of 0.27 mSv per patient, or 13 equivalent chest x-rays saved per patient, p < 0.0001. Additionally, the reduction in unnecessary duplicate imaging led to a 13.5% reduction in carbon emissions, p = 0.0002. CONCLUSIONS: Implementation of the POC CDST resulted in a significant impact on advanced imaging volume, saved effective dose, and reduction in carbon emissions. CRITICAL RELEVANCE STATEMENT: The implementation of a point-of-care clinical decision support tool may reduce multimodality ordering and advanced imaging volume, manifesting in reduced effective dose per patient and reduced estimated carbon emissions. Widespread utilization of the point-of-care clinical decision support tool has the potential to reduce imaging wait times. KEY POINTS: • Implementation of the point-of-care clinical decision support tool reduced the number of patients who simultaneously had a CT and MRI ordered for the same clinical indication compared to a standalone web-based clinical decision support tool. • The point-of-care clinical decision support tool reduced the absolute number of CT/MRI scans requested compared to the standalone web-based clinical decision support tool. • Utilization of the point-of-care clinical decision support tool led to a significant reduction in the effective dose per patient compared to the standalone web-based clinical decision support tool.
