Colorectal cancer patients under the age of 50 experience delays in primary care leading to emergency diagnoses: a population-based study.

AIM: The incidence of colorectal cancer in the under 50s is increasing. In this national population-based study we aim to show that missed opportunities for diagnosis in primary care are leading to referral delays and emergency diagnoses in young patients. METHOD: We compared the interval before diagnosis, presenting symptom(s) and the odds ratio (OR) of an emergency diagnosis for those under the age of 50 with older patients sourced from the cancer registry with linkage to a national database of primary-care records. RESULTS: The study included 7315 patients, of whom 508 (6.9%) were aged under 50 years, 1168 (16.0%) were aged 50-59, 2294 (31.4%) were aged 60-69 and 3345 (45.7%) were aged 70-79 years. Young patients were more likely to present with abdominal pain and via an emergency, and had the lowest percentage of early stage cancer. They experienced a longer interval between referral and diagnosis (12.5 days) than those aged 60-69, reflecting the higher proportion of referrals via the nonurgent pathway (33.3%). The OR of an emergency diagnosis did not differ with age if a red-flag symptom was noted at presentation, but increased significantly for young patients if the symptom was nonspecific. CONCLUSION: Young patients present to primary care with symptoms outside the national referral guidelines, increasing the likelihood of an emergency diagnosis.

Complications after discharge and delays in adjuvant chemotherapy following colonic resection: a cohort study of linked primary and secondary care data.

AIM: By understanding the reasons for delays in adjuvant chemotherapy (AC) after colonic resection, there is the potential to improve patient outcome. The aim of this study is to determine the extent and impact of complications after hospital discharge on delays to AC. METHOD: The study cohort included patients from Hospital Episode Statistics (HES) who had a colorectal cancer resection; linkage to primary care data was provided by the Clinical Practice Research Datalink (CPRD). Complications during the index hospital stay (from HES) and after discharge (from CPRD) were compared. The risk of late AC treatment (8 weeks or later) following a complication, stoma at the index procedure or emergency admission was described after accounting for age and Charlson score. A Cox hazards model determined the association of these factors with overall survival (OS). RESULTS: A total of 1266 patients underwent AC following colon cancer resection, of whom 598 (47.2%) received treatment within 8 weeks. Patients receiving late AC had a significantly higher proportion of re-operations (7.0% vs 3.3% P < 0.005) and wound infections (5.5% vs 3.7% P = 0.042), with 96% of the latter only being noted in CPRD. In multivariate analysis, the risk of AC delay significantly increased following a complication (OR 1.53, 95% CI 1.16-2.03, P = 0.003) or a stoma at the index operation. AC delay was associated with worse OS [hazard ratio (HR) 1.44, 95% CI 1.16-1.79, P = 0.001], as was an emergency admission (HR 1.59, 95% CI 1.21-1.98, P < 0.0005). However, the presence of a complication did not independently reduce OS (HR 1.15, 95%CI 0.89-1.48, P = 0.295). CONCLUSION: The true extent and impact of complications following colonic resection is underestimated when only secondary care data are used.

Delays in referral from primary care are associated with a worse survival in patients with esophagogastric cancer.

NICE referral guidelines for suspected cancer were introduced to improve prognosis by reducing referral delays. However, over 20% of patients with esophagogastric cancer experience three or more consultations before referral. In this retrospective cohort study, we hypothesize that such a delay is associated with a worse survival compared with patients referred earlier. By utilizing Clinical Practice Research Datalink, a national primary care linked database, the first presentation, referral date, a number of consultations before referral and stage for esophagogastric cancer patients were determined. The risk of a referral after one or two consultations compared with three or more consultations was calculated for age and the presence of symptom fulfilling the NICE criteria. The risk of death according to the number of consultations before referral was determined, while accounting for stage and surgical management. 1307 patients were included. Patients referred after one (HR 0.80 95% CI 0.68-0.93 p = 0.005) or two consultations (HR 0.81 95% CI 0.67-0.98 p = 0.034) demonstrated significantly improved prognosis compared with those referred later. The risk of death was also lower for patients who underwent a resection, were younger or had an earlier stage at diagnosis. Those presenting with a symptom fulfilling the NICE criteria (OR 0.27 95% CI 0.21-0.35 p < 0.0001) were more likely to be referred earlier. This is the first study to demonstrate an association between a delay in referral and worse prognosis in esophagogastric patients. These findings should prompt further research to reduce primary care delays.

Are YouTube Videos Useful for Patients Interested in Botulinum Toxin for Bruxism?

PURPOSE: The study purpose was to evaluate the quality of provided information from YouTube videos (Google LLC, San Bruno, California) related to botulinum toxin injections for bruxism treatment. MATERIALS AND METHODS: In this cross-sectional study, a search of YouTube videos was conducted using the search term "Botox/bruxism." The first 150 videos were initially screened. After exclusions, the remaining 97 videos were independently examined by 3 researchers regarding demographic data and the content's usefulness. All videos were classified according to a usefulness score as poor, moderate, or excellent by evaluating content quality and flow. General video assessment included duration, views, "likes," "dislikes," and comments. Video content was analyzed by an 8-point score list. All videos were classified based on sources (universities and hospitals, health care professionals, health companies, individual users, or others) and types (patient's experience, educational, or scientifically erroneous or unproven information). The obtained data were analyzed according to the usefulness score. For statistical analysis, the χ2 test, Kruskal-Wallis test, and Pearson test were performed. Interobserver agreement was calculated as the κ score. RESULTS: The usefulness scores of the included videos ranged from poor (0) to excellent (2) (mean, 0.65). When video demographic data were compared with the usefulness score, the durations of excellent and moderate videos were statistically significantly longer than those of poor videos (P = .022 and P < .05, respectively). However, no statistically significant differences were found between the usefulness score and the number of views, likes, dislikes, and comments (P > .05). A statistically significant relationship was found between video demographic data and the source of upload (P < .05). The videos uploaded by individual users were longer than the other videos and had higher numbers of likes, dislikes, and comments than the other videos (P < .05). No significant correlation was found between video usefulness and the source of upload (P = .697) or type of video (P = .228). CONCLUSIONS: Health care professionals should assess YouTube videos related to Botox (Botox, Allergan, Inc, Irvine, California) and bruxism for clinical accuracy and content quality and recommend to patients those videos that meet professionals' standards and achieve the intended educational goals.

Vocal palsy increases the risk of lower respiratory tract infection in low-risk, low-morbidity patients undergoing thyroidectomy for benign disease: A big data analysis.

OBJECTIVES: Thyroidectomy is the commonest operation that places normally functioning laryngeal nerves at risk of injury. Vocal palsy is a major risk factor for dysphonia, dysphagia, and less commonly, airway obstruction. We investigated the association between post-thyroidectomy vocal palsy and long-term risks of pneumonia and laryngeal failure. DESIGN: An N=near-all analysis of the English administrative dataset using a previously validated informatics algorithm to identify young and otherwise low-risk patients undergoing first-time elective thyroidectomy for benign disease. Information about age, sex, morbidities, social deprivation and post-operative and late complications were derived. MAIN OUTCOME MEASURES: Between 2004 and 2012, 43 515 patients between the ages of 20 and 69 who had no history of cancer, neurological, or respiratory disease underwent elective total or hemithyroidectomy without concomitant or late neck dissection, parathyroidectomy or laryngotracheal surgery for benign thyroid disease for the first and only time. Information about age, sex, morbidities and in-hospital and late complications was recorded. RESULTS: Mean age at surgery was 46±12. There was a strong female preponderance (85%), and most patients (89%) had no recorded Charlson comorbidities Most patients (65%) underwent hemithyroidectomy. Late vocal palsy was recorded in 449 (1.03%) patients, and its occurrence was an independent risk factor for emergency hospital readmission (n=7113; Hazard Ratio 1.52; 95% confidence interval 1.21-1.91), hospitalisation for lower respiratory tract infection (n=944; HR 2.04; 95% CI 1.07-3.75), dysphagia (n=564; HR 3.47; 95% CI 1.57-7.65) and gastrostomy/tracheostomy placement (n=80; HR 20.8; 95% CI 2.5-171.2). Independent risk factors for late vocal palsy were age, burden of morbidities, total thyroidectomy, post operative bleeding, male sex, and annual surgeon volume <30. CONCLUSIONS: There is a significant association between post-thyroidectomy vocal palsy and long-term risks of hospital readmission, dysphagia, hospitalisation for lower respiratory tract infection, and gastrostomy/tracheostomy tube placement. This adds weight to the need, from a thyroid surgical perspective, to undertake universal post-thyroidectomy laryngeal surveillance as a minimum standard of care, with a focus on post-operative dysphagia and aspiration, and from a medical/respiratory perspective, to initiate investigations to identify occult vocal palsy in patients who present with pneumonia, who have a history of thyroid surgery.

A national analysis of trends, outcomes and volume-outcome relationships in thyroid surgery.

OBJECTIVES: Thyroid conditions are common, and their incidence is increasing. Surgery is the mainstay treatment for many thyroid conditions, and understanding its utilisation trends and morbidity is central to improving patient care. DESIGN: An N = near-all analysis of the English administrative dataset to identify trends in thyroid surgery specialisation, volume-outcome relationships, and the incidence and risk factors for short- and long-term morbidity. MAIN OUTCOME MEASURES: Between 2004 and 2012, 72 594 patients underwent elective thyroidectomy in England. Information about age, sex, morbidities, nature of thyroid disease and surgery, adjuvant treatments and complications including hypocalcaemia and vocal palsy was recorded. RESULTS: Mean age at surgery was 49 ± 30, and a female predominance (82%) was observed. Most patients underwent hemithyroidectomy (51%) or total thyroidectomy (32%). Patients underwent surgery for benign (52.5%), benign inflammatory (21%) and malignant (17%) thyroid diseases. Thyroid surgery grew by 2.9% a year and increased in specialisation. Increased surgeon volume significantly reduced lengths of stay: the proportion of length of stay outliers fell from 11.8% for patients of occasional thyroidectomists (<5 per year) to 2.8% for patients of high-volume surgeons (>50 thyroidectomies a year). Post-discharge vocal palsy and hypocalcaemia occurred in 1.87% and 1.58% of cases, respectively. High-volume surgeons had a reduced incidence of vocal palsy, and volumes >30 were consistently protective. CONCLUSIONS: Thyroid surgery is increasingly specialised. High-volume surgeons, that is patients who perform 50 or more thyroidectomies per year, achieve lower complications and shorter lengths of stay.

A stratified analysis of the perioperative outcome of 17623 patients undergoing major head and neck cancer surgery in England over 10 years: Towards an Informatics-based Outcomes Surveillance Framework.

OBJECTIVES: To perform a national analysis of the perioperative outcome of major head and neck cancer surgery to develop a stratification strategy and outcomes assessment framework using hospital administrative data. DESIGN: A Hospital Episode Statistics N = near-all analysis. SETTINGS: The English National Health Service. MAIN OUTCOME MEASURES: Local audit data were used to assess and triangulate the quality of the administrative dataset. Within the national dataset, cancer sites, morbidities, social deprivation, treatment, complications, and in-hospital mortality were recorded. RESULTS: Within local audit datasets, the accuracy of assigning newly-derived Cancer Site Strata and Resection Strata were 92.3% and 94.2%, respectively. Accuracy of morbidities assignment was 97%. Within the national dataset, we identified 17 623 major head and neck cancer resections between 2002 and 2012. There were 12 413 males and mean age at surgery was 63 ± 12 years. The commonest cancer site strata were oral cavity (42%) and larynx-hypopharynx (32%). The commonest resection site was the larynx (n = 4217), and 13 211 and 11 841 patients had neck dissection and flap-based reconstruction, respectively. There were prognostically significant baseline differences between patients with oromandibular and pharyngolaryngeal malignancy. Patients with pharyngolaryngeal malignancies had a greater burden of morbidities, lower socio-economic status, fewer primary resections, and a sixfold increased risk of undergoing their major resection during an emergency hospital admission. Mean length of stay was 25 days and each complication linearly increased it by 9.6 days. There were 609 (3.5%) in-hospital deaths and a basket of seven medical and three surgical complications significantly increased the risk of in-hospital death. At least one potentially lethal complication occurred in 26% of patients. The risk of in-hospital death in a patient with no potentially lethal complication was 1.1% and this increased to 6% with one potentially lethal complication, and to 15.1% if two potentially lethal complications occurred in one patient. Complex oral-pharyngeal resections and pharyngolaryngectomies had the highest risks of complications and mortality. CONCLUSION: Mortality following head and neck cancer surgery shows variation across different resection strata. We propose an Informatics-based Framework for Outcomes Surveillance (IFOS) in Head and Neck Surgery for perpetual quality assurance, using the local hospital coding data or its collated destination, the national administrative dataset.

Defining the timing and causes of death amongst patients undergoing colorectal resection in England.

AIM: Historically, postoperative deaths have been reported up to 30 days following surgery. There is, however, emerging evidence that deaths attributable to surgery continue to occur much later than this time frame. This aim of this study was to analyse the timing and causes of mortality following colorectal resection. METHOD: Data were obtained from the Hospital Episode Statistics database with linkage to mortality data from the Office for National Statistics. Patients who underwent colorectal resection between April 2001 and February 2007 were included. Causes of death were classified into colorectal cancer (CRC), other malignancy, cardiac, respiratory, gastrointestinal, neurological and other. RESULTS: During the study period 171 791 patients underwent a colorectal resection. Thirty-day mortality rates for elective procedures were 1.3, 3.5, 7.0 and 12.1% for the ≤ 65, 66-75, 76-85 and > 85 year age groups, respectively, compared with 2.2, 5.4, 9.8 and 16.7% at 90 days. For elective operations, at 30 days, 38.6% of patients who died had CRC recorded as the primary cause of death, whilst 25.4% died of cardiac causes. In the younger population undergoing a resection, deaths due to cardiac causes were significantly higher than the national average for the same age group even beyond 30 days (13.5% at 30 days, 11.1% at 90 days and 5.7% at 1 year). CONCLUSION: This study shows that deaths attributable to colorectal surgery occur beyond the conventionally utilized 30-day period. Information presented to patients on the basis of 30-day mortality estimates is likely to underestimate the true risk of surgical intervention.

The impact of shortened postgraduate surgical training on colorectal cancer outcome.

BACKGROUND: Shortened postgraduate surgical training reforms, known as Calman, have altered delivery of surgical training in the UK with reduced working hours and training time aiming to produce a more subspecialised workforce. AIMS: This study aims to compare rectal cancer surgical outcomes of Calman-trained consultants in a single institution to published data. Additionally, the study compared colorectal cancer surgical outcome between Calman-trained consultants (CTCs) and non-Calman consultants (NCTCs) in a national dataset. METHODS: Local dataset Clinicopathological outcome of rectal cancer resection undertaken by CTCs in a single institution (2006-2010) were compared against NCTC counterparts. National dataset All elective colorectal cancer resections between 2004 and 2008 in English NHS hospitals were included. CTCs (present from 2004 onwards) were compared to NCTCs (present prior to 2004). Outcome measures included 30-day in-hospital mortality, reoperation and readmission rates. RESULTS: Local dataset One hundred thirteen patients were operated under five CTC. The 30-day in-hospital mortality for CTCs (1%) was favourable compared to published rates (3-5%). Local recurrence rate (4.4%) was comparable to NCTC (3.6%). National dataset Between 2004 and 2008, 44,106 patients underwent elective colorectal resection. Multiple regression demonstrated CTC patients had a reduced length of stay and reduced reoperation rate. No difference in mortality and unplanned readmission rates were seen. CONCLUSION: CTCs have similar safety outcome to NCTCs for colorectal cancer resection procedures. Further work is needed to assess the impact of further training reductions on clinical outcome.

Minimal-access colorectal surgery is associated with fewer adhesion-related admissions than open surgery.

BACKGROUND: This study aimed to describe national intermediate-term admission rates for incisional hernia or clinically apparent adhesions following colorectal surgery, and to compare rates following laparoscopic and open approaches. METHODS: Patients undergoing primary colorectal resection between 2002 and 2008 were included from the Hospital Episode Statistics database. Subsequent inpatient admissions were extracted for up to 3 years after the initial operation or to the end of the study period. Outcomes examined were admissions with a diagnosis of, or operative interventions for, incisional hernia or adhesions. RESULTS: A total of 187 148 patients were included between 2002 and 2008, with median follow-up of 31·8 (interquartile range 13·1-35·3) months. Some 8885 (4·7 per cent) of these patients were admitted with a diagnosis of, or underwent a repair of, an incisional hernia. In multiple regression analysis, use of laparoscopy was not a predictor of operative intervention for incisional hernia (odds ratio 1·09, 95 per cent confidence interval (c.i.) 0·99 to 1·21; P = 0·083). Some 15 125 (8·1 per cent) of the patients were admitted with a diagnosis of adhesions or had a procedure for division of adhesions. Overall, 3·5 per cent (6637 of 187 148) of patients underwent adhesiolysis. Patients selected for a laparoscopic procedure had lower rates of admission for adhesions (6·3 per cent (692 of 11 013) for laparoscopic versus 8·2 per cent (14 433 of 176 135) for open surgery; P < 0·001) and reintervention for adhesions (2·8 per cent (305 of 11 013) versus 3·6 per cent (6325 of 176 135) respectively; P < 0·001) than those undergoing an open procedure. In multiple regression analysis, patients selected for a laparoscopic procedure had lower subsequent intervention rates for adhesions (odds ratio 0·80, 95 per cent c.i. 0·71 to 0·90; P < 0·001). DISCUSSION: Patients undergoing colorectal resection who are selected for the laparoscopic approach have a lower risk of developing clinically significant adhesions.

Hierarchical multilevel analysis of increased caseload volume and postoperative outcome after elective colorectal surgery.

BACKGROUND: The study aimed to explore the impact of surgeon and institution volume on outcome following colorectal surgery in England using multilevel hierarchical analysis. METHODS: An observational study design was used. All patients undergoing primary elective colorectal resection between 2000 and 2008 were included from the Hospital Episode Statistics database. Consultant surgeons and hospitals were divided into tertiles (low, medium and high volume) according to their mean annual colorectal cancer resection caseload. Outcome measures examined were postoperative 30-day mortality, 28-day readmission and reoperation, and length of stay. Hierarchical multiple regression analysis adjusted for age, sex, co-morbidity, social deprivation, year of surgery, operation type and surgical approach. RESULTS: A total of 109 261 elective cancer colorectal resections were included. High-volume consultant surgeons and hospitals were defined as performing more than 20·7 and 103·5 elective colorectal cancer procedures per year respectively. Consultant and hospital operative volumes increased throughout the study period. In hierarchical regression models, greater surgeon and institutional volume independently predicted only shorter length of hospital stay. No statistical association was observed between higher provider volume and postoperative mortality, 28-day reoperation or readmission rates. CONCLUSION: Increasing elective colorectal cancer caseload alone may have marginal postoperative benefit.

Mortality in high-risk emergency general surgical admissions.

BACKGROUND: There is increasing evidence of variable standards of care for patients undergoing emergency general surgery in the National Health Service (NHS). The aim of this study was to quantify and explore variability in mortality amongst high-risk emergency general surgery admissions to English NHS hospital Trusts. METHODS: The Hospital Episode Statistics (HES) database was used to identify high-risk emergency general surgery diagnoses (greater than 5 per cent national 30-day mortality rate). Adults admitted to English NHS Trusts with these diagnoses between 2000 and 2009 were included in the study. Thirty-day in-hospital mortality was adjusted for patient and hospital factors. Trusts were grouped into high- and low-mortality outliers, and resource availability was compared between high- and low-mortality outlier institutions. RESULTS: Some 367 796 patients admitted to 145 hospital Trusts were included in the study; the 30-day mortality rate was 15·6 per cent (institutional range 9·2-18·2 per cent). Fourteen and 24 hospital Trusts were identified as high- and low-mortality outlier institutions respectively. Intensive care and high-dependency bed resources, as well as greater institutional use of computed tomography (CT), were independent predictors of reduced mortality (P < 0·001). Low-mortality outlying Trusts had significantly more intensive care beds per 1000 hospital beds (20·8 versus 14·0; P = 0·017) and made significantly greater use of CT (24·6 versus 17·2 scans per bed per year; P < 0·001) and ultrasonography (42·5 versus 30·2 scans per bed per year; P < 0·001). CONCLUSION: There is significant variability in mortality risk between hospital Trusts treating high-risk emergency general surgery patients. Equitable access to essential hospital resources may reduce variability in outcomes.

Preoperative risk factors in 10 418 patients with prior myocardial infarction and 5241 patients with prior unstable angina undergoing elective coronary artery bypass graft surgery.

BACKGROUND: The EuroSCORE associates coronary artery bypass graft (CABG) surgery with higher perioperative risk in the first 3 months after a myocardial infarction (MI). The optimal scheduling of CABG surgery after unstable angina (UA) is unknown. We investigated the preoperative predictors of adverse outcomes in patients undergoing CABG with prior MI or UA and investigated the importance of time interval between the cardiac event and CABG. METHODS: The Hospital Episode Statistics database (April 2006-March 2010) was analysed for elective admissions for CABG. Independent preoperative patient factors influencing length of stay, readmission rates, and mortality, were identified by logistic regression and presented as adjusted odds ratios (ORs). RESULTS: A total of 10 418 patients with prior MI (mortality 1.8%) and 5241 patients with prior UA (mortality 2.2%) were included in the respective cohorts. Multiple risk factors were identified in each population including liver disease and renal failure. The time interval from cardiac event (MI or UA) to elective CABG surgery did not influence perioperative outcomes when analysed as a continuous measure or using the arbitrary 3-month threshold [MI, OR 1.1 (0.78-1.57) and UA, OR 0.65 (0.39-1.09)]. CONCLUSIONS: Our hypothesis generating data suggest that the increased risk currently allocated in the EuroSCORE for an interval of 3 months between MI and CABG should be critically re-evaluated. Furthermore, prior MI should not be discounted as a risk factor if it is more than 3 months old.

Current trends and progress in clinical applications of oocyte cryopreservation.

PURPOSE OF REVIEW: To delineate the current trends in the clinical application of oocyte cryopreservation. RECENT FINDINGS: Although the first live birth from oocyte cryopreservation was reported approximately three decades ago, significant improvement in the clinical application of oocyte cryopreservation took place only over the past decade. On the basis of the available evidence suggesting that success rates with donor oocyte vitrification are similar to that of IVF with fresh donor oocytes, the American Society of Reproductive Medicine has recently stated that oocyte cryopreservation should no longer be considered experimental for medical indications, outlying elective oocyte cryopreservation. Meanwhile, a few surveys on the attitudes toward oocyte cryopreservation revealed that elective use for the postponement of fertility is currently the most common indication for oocyte cryopreservation. Most recently, a randomized controlled trial revealed important evidence on the safety of nondonor oocyte cryopreservation, and confirmed that the clinical success of vitrification is comparable to that of IVF with fresh oocytes. SUMMARY: The evidence suggesting similar IVF success rates with both donor and nondonor cryopreserved oocytes compared with fresh oocytes will increase the utilization of elective oocyte cryopreservation. Appropriate counseling of women for oocyte cryopreservation requires the establishment of age-based clinical success rates with cryopreserved oocytes for various indications.

A national analysis of the outcome of major head and neck cancer surgery: implications for surgeon-level data publication.

OBJECTIVES: To undertake a national outcomes analysis following major head and neck cancer surgery in order to identify risk factors for complications and in-hospital mortality, as well as areas whose closer examination and formal benchmarking in the context of local and national quality assurance audits may lead to improved results for this condition. DESIGN: An analysis using Hospital Episode Statistics data. SETTINGS: All units undertaking major head and neck cancer surgery in England. MAIN OUTCOME MEASURES: Cancer sites, co-morbidities, social deprivation, surgical and non-surgical treatments, complications, and in-hospital mortality were recorded. Regression analysis was used for casemix adjustment and for identifying independent predictors of complications and mortality. Funnel plots were used for data visualisation. RESULTS: We identified 10,589 major head and neck cancer operations performed in England between 2006 and 2011. There were 7312 males, and mean age at surgery was 63 ± 13 years. Oral cavity (42%) and the larynx (28%) were the commonest cancer sites. At least one complication occurred in 33.1% of patients, and there were 322 (3.05%) in-hospital deaths. Variables associated with in-hospital mortality were trust volume, age, co-morbidities, performing emergency major surgery and performing a tracheostomy or reconstructive surgery. Occurrence of major medical complications including pulmonary infections (7%), major acute cardiovascular events (4.7%) and acute renal failure (0.6%) also increased mortality risk. The analysis identified units that were outside of crude and risk-adjusted 99.8% limits of confidence for complications and mortality. CONCLUSION: Mortality following head and neck cancer surgery shows significant national variation and is associated with fixed risk factors like age and co-morbidities, but also with modifiable risk factors like performing major surgery during an emergency admission, tracheostomy, reconstructive surgery and medical complications. We propose that the quality of tracheostomy care, reconstructive surgery, emergency major surgery rate, and occurrence and treatment of major medical complications should be closely examined and formally benchmarked as part of loco-regional and national quality improvement audits.

Association between patient and general practice characteristics and unplanned first-time admissions for cancer: observational study.

BACKGROUND: To identify patient and general practice (GP) characteristics associated with emergency (unplanned) first admissions for cancer in secondary care. METHODS: Patients who had a first-time admission with a primary diagnosis of cancer during 2007/08 to 2009/10 were identified from administrative hospital data. We modelled the associations between the odds of these admissions being unplanned and various patient and GP practice characteristics using national data sets, including the Quality and Outcomes Framework (QOF). RESULTS: There were 639,064 patients with a first-time admission for cancer, with 139,351 unplanned, from 7957 GP practices. The unplanned proportion ranged from 13.9% (patients aged 15-44 years) to 44.9% (patients aged 85 years and older, P<0.0001), with large variation by ethnicity (highest in Asians), deprivation, rurality and cancer type. In unadjusted analyses, all included patient and practice-level variables were statistically significant predictors of the admissions being unplanned. After adjustment, patient area-level deprivation was a key factor (most deprived compared with least deprived quintile OR 1.36, 95% CI 1.32-1.40). Higher total QOF performance protected against unplanned admission (OR 0.94 per 100 points; 95% CI 0.91-0.97); having no GPs with a UK primary medical qualification (OR 1.08, 95% CI 1.04-1.11) and being less able to offer appointments within 48 h were associated with higher odds. CONCLUSION: We have identified some patient and practice characteristics associated with a first-time admission for cancer being unplanned. The former could be used to help identify patients at high risk, while the latter raise questions about the role of practice organisation and staff training.

Systematic review of discharge coding accuracy.

INTRODUCTION: Routinely collected data sets are increasingly used for research, financial reimbursement and health service planning. High quality data are necessary for reliable analysis. This study aims to assess the published accuracy of routinely collected data sets in Great Britain. METHODS: Systematic searches of the EMBASE, PUBMED, OVID and Cochrane databases were performed from 1989 to present using defined search terms. Included studies were those that compared routinely collected data sets with case or operative note review and those that compared routinely collected data with clinical registries. RESULTS: Thirty-two studies were included. Twenty-five studies compared routinely collected data with case or operation notes. Seven studies compared routinely collected data with clinical registries. The overall median accuracy (routinely collected data sets versus case notes) was 83.2% (IQR: 67.3-92.1%). The median diagnostic accuracy was 80.3% (IQR: 63.3-94.1%) with a median procedure accuracy of 84.2% (IQR: 68.7-88.7%). There was considerable variation in accuracy rates between studies (50.5-97.8%). Since the 2002 introduction of Payment by Results, accuracy has improved in some respects, for example primary diagnoses accuracy has improved from 73.8% (IQR: 59.3-92.1%) to 96.0% (IQR: 89.3-96.3), P= 0.020. CONCLUSION: Accuracy rates are improving. Current levels of reported accuracy suggest that routinely collected data are sufficiently robust to support their use for research and managerial decision-making.

Trends and associated factors for Covid-19 hospitalisation and fatality risk in 2.3 million adults in England.

The Covid-19 mortality rate varies between countries and over time but the extent to which this is explained by the underlying risk in those infected is unclear. Using data on all adults in England with a positive Covid-19 test between 1st October 2020 and 30th April 2021 linked to clinical records, we examined trends and risk factors for hospital admission and mortality. Of 2,311,282 people included in the study, 164,046 (7.1%) were admitted and 53,156 (2.3%) died within 28 days of a positive Covid-19 test. We found significant variation in the case hospitalisation and mortality risk over time, which remained after accounting for the underlying risk of those infected. Older age groups, males, those resident in areas of greater socioeconomic deprivation, and those with obesity had higher odds of admission and death. People with severe mental illness and learning disability had the highest odds of admission and death. Our findings highlight both the role of external factors in Covid-19 admission and mortality risk and the need for more proactive care in the most vulnerable groups.

A colorectal perspective on voluntary submission of outcome data to clinical registries.

BACKGROUND: The aim of the study was to identify outcome differences amongst patients undergoing resection of colorectal cancer at English National Health Service trusts using Hospital Episode Statistics (HES). A comparison was undertaken of trusts that submitted and those that did not submit, or submitted only poorly, voluntarily to a colorectal clinical registry, the National Bowel Cancer Audit Programme (NBOCAP). METHODS: The NBOCAP data set was used to classify trusts according to submitter status. HES data were used for outcome analysis. Data for major resections of colorectal cancer performed between 1 August 2007 and 31 July 2008 were obtained from HES. Trusts not submitting data to NBOCAP and those submitting less than 10 per cent of their total workload were termed 'non-submitters'. HES data for 30-day mortality, length of stay and readmission rates were compared according to submitter and non-submitter status in multifactorial analyses. RESULTS: A total of 17,722 patients were identified from HES for inclusion. Unadjusted 30-day in-hospital mortality rates were higher in non-submitting than in submitting trusts (5·2 versus 4·0 per cent; P = 0·005). Submitter status was independently associated with reduced 30-day mortality (odds ratio 0·76, 95 per cent confidence interval 0·61 to 0·96; P = 0·021) in regression analysis. CONCLUSION: A higher postoperative mortality rate following resection of colorectal cancer was found in trusts that do not voluntarily report data to NBOCAP. Implications regarding the voluntary nature of submission to such registries should be reviewed if they are to be used for outcome benchmarking.
