RESUMO
BACKGROUND: Life-saving emergency major resection of colorectal cancer (CRC) is a high-risk procedure. Accurate prediction of postoperative mortality for patients undergoing this procedure is essential for both healthcare performance monitoring and preoperative risk assessment. Risk-adjustment models for CRC patients often include patient and tumour characteristics, widely available in cancer registries and audits. The authors investigated to what extent inclusion of additional physiological and surgical measures, available through linkage or additional data collection, improves accuracy of risk models. METHODS: Linked, routinely-collected data on patients undergoing emergency CRC surgery in England between December 2016 and November 2019 were used to develop a risk model for 90-day mortality. Backwards selection identified a 'selected model' of physiological and surgical measures in addition to patient and tumour characteristics. Model performance was assessed compared to a 'basic model' including only patient and tumour characteristics. Missing data was multiply imputed. RESULTS: Eight hundred forty-six of 10 578 (8.0%) patients died within 90 days of surgery. The selected model included seven preoperative physiological and surgical measures (pulse rate, systolic blood pressure, breathlessness, sodium, urea, albumin, and predicted peritoneal soiling), in addition to the 10 patient and tumour characteristics in the basic model (calendar year of surgery, age, sex, ASA grade, TNM T stage, TNM N stage, TNM M stage, cancer site, number of comorbidities, and emergency admission). The selected model had considerably better discrimination compared to the basic model (C-statistic: 0.824 versus 0.783, respectively). CONCLUSION: Linkage of disease-specific and treatment-specific datasets allowed the inclusion of physiological and surgical measures in a risk model alongside patient and tumour characteristics, which improves the accuracy of the prediction of the mortality risk for CRC patients having emergency surgery. This improvement will allow more accurate performance monitoring of healthcare providers and enhance clinical care planning.

OBJECTIVES: (1) To explore differences in educational attainment between children born with isolated clefts and the general population at ages 5, 7 and 11 years; (2) to describe longitudinal changes in attainment among children with cleft through primary education. DESIGN: Analysis of Cleft Registry and Audit Network data linked to national educational outcomes. SETTING: English state schools. PATIENTS: 832 children born with isolated cleft, aged 5 years in 2006-2008. MAIN OUTCOME MEASURES: Difference in teacher-assessed attainment between children with a cleft and general population at each age, for all children and by cleft type. Percentage of children with low attainment at age 5 years who had low attainment at age 11 years, for all children and by cleft type. RESULTS: Children with a cleft had lower attainment than the general population in all subject areas (Z-score range: -0.29 (95% CI -0.36 to -0.22) to -0.22 (95% CI -0.29 to -0.14)). This difference remained consistent in size at all ages, and was larger among children with a cleft affecting the palate (cleft palate/cleft lip and palate (CP/CLP)) than those with a cleft lip (CL). Of 216 children with low attainment in any subject at age 5 years, 54.2% had low attainment in at least one subject at age 11 years. Compared with children with CL, those with CP/CLP were more likely to have persistent low attainment. CONCLUSIONS: An educational attainment gap for children born with isolated clefts is evident throughout primary education. Almost half of children with low attainment at age 5 years achieve normal attainment at age 11 years.

BACKGROUND AND AIMS: Identifying international differences in utilization and outcomes of liver transplantation (LT) after donation after circulatory death (DCD) donation provides a unique opportunity for benchmarking and population-level insight. METHODS: Adult (≥18 years) LT data between 2008 and 2018 from the UK and US were used to assess mortality and graft failure after DCD LT. We used time-dependent Cox-regression methods to estimate hazard ratios (HR) for risk-adjusted short-term (0-90 days) and longer-term (90 days-5 years) outcomes. RESULTS: One-thousand five-hundred-and-sixty LT receipts from the UK and 3426 from the US were included. Over the study period, the use of DCD livers increased from 15.7% to 23.9% in the UK compared to 5.1% to 7.6% in the US. In the UK, DCD donors were older (UK:51 vs. US:33 years) with longer cold ischaemia time (UK: 437 vs. US: 333 min). Recipients in the US had higher Model for End-stage Liver Disease (MELD) scores, higher body mass index, higher proportions of ascites, encephalopathy, diabetes and previous abdominal surgeries. No difference in the risk-adjusted short-term mortality or graft failure was observed between the countries. In the longer-term (90 days-5 years), the UK had lower mortality and graft failure (adj.mortality HR:UK: 0.63 (95% CI: 0.49-0.80); graft failure HR: UK: 0.72, 95% CI: 0.58-0.91). The cumulative incidence of retransplantation was higher in the UK (5 years: UK: 11.9% vs. 4.6%; p < .001). CONCLUSIONS: For those receiving a DCD LT, longer-term post-transplant outcomes in the UK are superior to the US, however, significant differences in recipient illness, graft quality and access to retransplantation were seen between the two countries.

BACKGROUND: Methods for linking records between two datasets are well established. However, guidance is needed for linking more than two datasets. Using all 'pairwise linkages'-linking each dataset to every other dataset-is the most inclusive, but resource-intensive, approach. The 'spine' approach links each dataset to a designated 'spine dataset', reducing the number of linkages, but potentially reducing linkage quality. METHODS: We compared the pairwise and spine linkage approaches using real-world data on patients undergoing emergency bowel cancer surgery between 31 October 2013 and 30 April 2018. We linked an administrative hospital dataset (Hospital Episode Statistics; HES) capturing patients admitted to hospitals in England, and two clinical datasets comprising patients diagnosed with bowel cancer and patients undergoing emergency bowel surgery. RESULTS: The spine linkage approach, with HES as the spine dataset, created an analysis cohort of 15â826 patients, equating to 98.3% of the 16â100 patients identified using the pairwise linkage approach. There were no systematic differences in patient characteristics between these analysis cohorts. Associations of patient and tumour characteristics with mortality, complications and length of stay were not sensitive to the linkage approach. When eligibility criteria were applied before linkage, spine linkage included 14â509 patients (90.0% compared with pairwise linkage). CONCLUSION: Spine linkage can be used as an efficient alternative to pairwise linkage if case ascertainment in the spine dataset and data quality of linkage variables are high. These aspects should be systematically evaluated in the nominated spine dataset before spine linkage is used to create the analysis cohort.

BACKGROUND: Probabilistic linkage can link patients from different clinical databases without the need for personal information. If accurate linkage can be achieved, it would accelerate the use of linked datasets to address important clinical and public health questions. OBJECTIVE: We developed a step-by-step process for probabilistic linkage of national clinical and administrative datasets without personal information, and validated it against deterministic linkage using patient identifiers. STUDY DESIGN AND SETTING: We used electronic health records from the National Bowel Cancer Audit and Hospital Episode Statistics databases for 10,566 bowel cancer patients undergoing emergency surgery in the English National Health Service. RESULTS: Probabilistic linkage linked 81.4% of National Bowel Cancer Audit records to Hospital Episode Statistics, vs. 82.8% using deterministic linkage. No systematic differences were seen between patients that were and were not linked, and regression models for mortality and length of hospital stay according to patient and tumour characteristics were not sensitive to the linkage approach. CONCLUSION: Probabilistic linkage was successful in linking national clinical and administrative datasets for patients undergoing a major surgical procedure. It allows analysts outside highly secure data environments to undertake linkage while minimizing costs and delays, protecting data security, and maintaining linkage quality.

OBJECTIVES: To examine school absence and academic achievement among 7-year-old children with isolated orofacial clefts in England. DESIGN: Analysis of educational data linked to national cleft registry and administrative hospital data. SETTING: English state schools. PATIENTS: 3523 children with isolated clefts aged 7 years between 2006 and 2014. MAIN OUTCOME MEASURES: Annual school absence and reaching the national 'expected level' according to teacher-assessed academic achievement. RESULTS: Children with isolated clefts had higher mean annual school absence (10.5 days) than their peers in the national population (8.9 days). Total absence was higher in children with a cleft lip and palate (CLP; 11.3 days) or with a cleft palate only (CPO; 10.5 days) than in children with a cleft lip only (CLO; 9.5 days). The percentage reaching the expected academic level decreased with increasing school absence (from 77.4% (923/1192) with annual school absence ≤5 days to 43.4% (193/445) with annual school absence >20 days). However, differences in school absence did not explain that children with CPO (65.9% reaching expected level) or CLP (66.1% reaching expected level) had poorer levels of academic achievement than children with CLO (73.5% reaching expected level). Children with a cleft were twice as often recognised as having special education needs (40.5%) than their peers (21.6%). CONCLUSIONS: School absence and cleft type are both independently associated with school attainment at 7 years. Children with an isolated cleft, especially when the palate is involved, and those with high levels of school absence may benefit from increased support addressing their educational needs.

INTRODUCTION: Mastectomy patients' satisfaction with reconstructive options has not been examined. METHODS: A national study measured 18-month satisfaction with reconstructive options and collected case-mix and reconstructive offer and uptake data on breast cancer patients having mastectomy with or without immediate reconstruction (IR) in England between January 2008 and March 2009. Multivariable logistic regression examined the relationship between satisfaction, age, IR offer and uptake, and clinical suitability. RESULTS: Of 4796 patients, 1889 were not offered IR, 1489 declined an offer and 1418 underwent it. Women not offered IR were more likely older, obese or smokers and had higher ASA grades, ECOG scores, tumour burdens and adjuvant chemotherapy and radiotherapy likelihoods (9% of lowest suitability group offered IR; 81% in highest suitability group). 83.7% were satisfied with their reconstructive options, varying significantly by IR offer and uptake (76.1% for those not offered IR; 85.8% for those who declined IR; 91.7% following IR). Older women and women deemed more suitable for IR were more often satisfied (p-values <0.001). CONCLUSIONS: Satisfaction varied by offer and uptake status, age and suitability score. Clinicians should target equity for women deemed unsuitable by exploring their needs and desired outcomes, standardising operative fitness assessments and utilising shared decision-making aids.

OBJECTIVE: To examine geographic variation in use of surgery for female stress urinary incontinence (SUI), mainly midurethral mesh tape insertions, in the English National Health Service (NHS). DESIGN: National cohort study. SETTING: NHS hospitals. PARTICIPANTS: 27 997 women aged 20 years or older who had a first SUI surgery in an English NHS Hospital between April 2013 and March 2016 and a diagnosis of SUI at the same time as the procedure. METHODS: Multilevel Poisson regression was used to adjust for geographic differences in age, ethnicity, prevalence of long-term illness and socioeconomic deprivation. PRIMARY OUTCOME MEASURE: Rate of surgery for SUI per 100 000 women/year at two geographic levels: Clinical Commissioning Group (CCG; n=209) and Sustainability and Transformation Partnership (STP; n=44). RESULTS: The rate of surgery for SUI was 40 procedures per 100 000 women/year. Risk-adjusted rates ranged from 20 to 106 procedures per 100 000 women/year across CCGs and 24 to 69 procedures per 100 000 women/year across the STP areas. These regional differences were only partially explained by demographic characteristics as adjustment reduced variance of surgery rates by 16% among the CCGs and 35% among the STPs. CONCLUSIONS: Substantial geographic variation exists in the use of surgery for female SUI in the English NHS, suggesting that women in some areas are more likely to be treated compared with women with the same condition in other areas. The variation reflects differences in how national guidelines are being interpreted in the context of the ongoing debate about the safety of SUI surgery.

BACKGROUND: Policies that encourage patient choice and hospital competition have been introduced across several countries with the purpose of improving the quality of health care services. The objective of the current national cohort study was to analyze the correlation between choice and competition on outcomes after cancer surgery using prostate cancer as a case study. METHODS: The analyses included all men who underwent prostate cancer surgery in the United Kingdom between 2008 and 2011 (n = 12,925). Multilevel logistic regression was used to assess the effect of a radical prostatectomy center being located in a competitive environment (based on the number of centers within a threshold distance) and being a successful competitor (based on the ability to attract patients from other hospitals) on 3 patient-level outcomes: postoperative length of hospital stay >3 days, 30-day emergency readmissions, and 2-year urinary complications. RESULTS: With adjustment for patient characteristics, men who underwent surgery in centers located in a stronger competitive environment were less likely to have a 30-day emergency readmission, irrespective of the type or volume of procedures performed at each center (odds ratio, 0.46; 95% confidence interval, 0.36-0.60; P = .005). Men who received treatment at centers that were successful competitors were less likely to have a length of hospital stay >3 days (odds ratio, 0.49; 95% confidence interval, 0.25-0.94; P = .02). CONCLUSIONS: The current results suggest for the first time that hospital competition improves short-term outcomes after prostate cancer surgery. Further evaluation of the potential role of patient choice and hospital competition is required to inform health service design in contrast to the role of top-down-driven approaches, which have focused on centralization of services.

OBJECTIVE: We adapted a composite neonatal adverse outcome indicator (NAOI), originally derived in Australia, and assessed its feasibility and validity as an outcome indicator in English administrative hospital data. DESIGN: We used Hospital Episode Statistics (HES) data containing information infants born in the English National Health Service (NHS) between 1 April 2014 and 31 March 2015. The Australian NAOI was mapped to diagnoses and procedure codes used within HES and modified to reflect data quality and neonatal health concerns in England. To investigate the concurrent validity of the English NAOI (E-NAOI), rates of NAOI components were compared with population-based studies. To investigate the predictive validity of the E-NAOI, rates of readmission and death in the first year of life were calculated for infants with and without E-NAOI components. RESULTS: The analysis included 484 007 (81%) of the 600 963 eligible babies born during the timeframe. 114/148 NHS trusts passed data quality checks and were included in the analysis. The modified E-NAOI included 23 components (16 diagnoses and 7 procedures). Among liveborn infants, 5.4% had at least one E-NAOI component recorded before discharge. Among newborns discharged alive, the E-NAOI was associated with a significantly higher risk of death (0.81% vs 0.05%; p<0.001) and overnight hospital readmission (15.7% vs 7.1%; p<0.001) in the first year of life. CONCLUSIONS: A composite NAOI can be derived from English hospital administrative data. This E-NAOI demonstrates good concurrent and predictive validity in the first year of life. It is a cost-effective way to monitor neonatal outcomes.

OBJECTIVES: We used national data to study differences in academic achievement between 5-year-old children with an isolated oral cleft and the general population. We also assessed differences by cleft type. METHODS: Children born in England with an oral cleft were identified in a national cleft registry. Their records were linked to databases of hospital admissions (to identify additional anomalies) and educational outcomes. Z-scores (signed number of SD actual score is above national average) were calculated to make outcome scores comparable across school years and across six assessed areas (personal development, communication and language, maths, knowledge of world, physical development andcreative development). RESULTS: 2802 children without additional anomalies, 5 years old between 2006 and 2012, were included. Academic achievement was significantly below national average for all six assessed areas with z-scores ranging from -0.24 (95% CI -0.32 to -0.16) for knowledge of world to -0.31 (-0.38 to -0.23) for personal development. Differences were small with only a cleft lip but considerably larger with clefts involving the palate. 29.4% of children were documented as having special education needs (national rate 9.7%), which varied according to cleft type from 13.2% with cleft lip to 47.6% with bilateral cleft lip and palate. CONCLUSIONS: Compared with national average, 5-year-old children with an isolated oral cleft, especially those involving the palate, have significantly poorer academic achievement across all areas of learning. These outcomes reflect results of modern surgical techniques and multidisciplinary approach. Children with a cleft may benefit from extra academic support when starting school.

BACKGROUND: A recent randomised controlled trial (RCT) demonstrated that induction of labour at 39 weeks of gestational age has no short-term adverse effect on the mother or infant among nulliparous women aged ≥35 years. However, the trial was underpowered to address the effect of routine induction of labour on the risk of perinatal death. We aimed to determine the association between induction of labour at ≥39 weeks and the risk of perinatal mortality among nulliparous women aged ≥35 years. METHODS AND FINDINGS: We used English Hospital Episode Statistics (HES) data collected between April 2009 and March 2014 to compare perinatal mortality between induction of labour at 39, 40, and 41 weeks of gestation and expectant management (continuation of pregnancy to either spontaneous labour, induction of labour, or caesarean section at a later gestation). Analysis was by multivariable Poisson regression with adjustment for maternal characteristics and pregnancy-related conditions. Among the cohort of 77,327 nulliparous women aged 35 to 50 years delivering a singleton infant, 33.1% had labour induced: these women tended to be older and more likely to have medical complications of pregnancy, and the infants were more likely to be small for gestational age. Induction of labour at 40 weeks (compared with expectant management) was associated with a lower risk of in-hospital perinatal death (0.08% versus 0.26%; adjusted risk ratio [adjRR] 0.33; 95% CI 0.13-0.80, P = 0.015) and meconium aspiration syndrome (0.44% versus 0.86%; adjRR 0.52; 95% CI 0.35-0.78, P = 0.002). Induction at 40 weeks was also associated with a slightly increased risk of instrumental vaginal delivery (adjRR 1.06; 95% CI 1.01-1.11, P = 0.020) and emergency caesarean section (adjRR 1.05; 95% CI 1.01-1.09, P = 0.019). The number needed to treat (NNT) analysis indicated that 562 (95% CI 366-1,210) inductions of labour at 40 weeks would be required to prevent 1 perinatal death. Limitations of the study include the reliance on observational data in which gestational age is recorded in weeks rather than days. There is also the potential for unmeasured confounders and under-recording of induction of labour or perinatal death in the dataset. CONCLUSIONS: Bringing forward the routine offer of induction of labour from the current recommendation of 41-42 weeks to 40 weeks of gestation in nulliparous women aged ≥35 years may reduce overall rates of perinatal death.

Linked datasets are an important resource for epidemiological and clinical studies, but linkage error can lead to biased results. For data security reasons, linkage of personal identifiers is often performed by a third party, making it difficult for researchers to assess the quality of the linked dataset in the context of specific research questions. This is compounded by a lack of guidance on how to determine the potential impact of linkage error. We describe how linkage quality can be evaluated and provide widely applicable guidance for both data providers and researchers. Using an illustrative example of a linked dataset of maternal and baby hospital records, we demonstrate three approaches for evaluating linkage quality: applying the linkage algorithm to a subset of gold standard data to quantify linkage error; comparing characteristics of linked and unlinked data to identify potential sources of bias; and evaluating the sensitivity of results to changes in the linkage procedure. These approaches can inform our understanding of the potential impact of linkage error and provide an opportunity to select the most appropriate linkage procedure for a specific analysis. Evaluating linkage quality in this way will improve the quality and transparency of epidemiological and clinical research using linked data.

BACKGROUND: Medical treatment for breast cancer is associated with substantial toxicity and patient burden. There is less known about the impact of surgical complications. Understanding this impact could provide important information for patients when they are considering surgical options. METHODS: Between 2008 and 2009, the UK National Mastectomy and Breast Reconstruction Audit recorded surgical complications for a prospective cohort of 17,844 women treated for breast cancer at 270 hospitals; 6405 of these women were surveyed about their quality of life 18 months after surgery. Breast appearance, emotional well-being, and physical well-being were quantified on 0- to 100-point scales. Linear multiple regression models, controlling for a range of baseline prognostic factors, were used to compare the scores of patients who had complications with the scores of those who did not. RESULTS: The overall complication rate was 10.2%. Complications were associated with little or no impairment in women undergoing mastectomy without reconstruction or with delayed reconstruction. The association was much larger for flap-related complications suffered during immediate reconstruction. The breast-appearance scores (adjusted mean difference, -23.8; 95% confidence interval [CI], -31.0 to -16.6) and emotional well-being scores (adjusted mean difference, -14.0; 95% CI, -22.0 to -6.0) of these patients were much lower than those of any other patient group. Implant-related complications were not associated with a lower quality of life in any surgical group. CONCLUSIONS: There is a strong case for prospectively collecting flap-complication rates at the surgeon and surgical unit level and for allowing patients to access these data when they make choices about their breast cancer surgery.

BACKGROUND: This national prospective cohort study compared the patient-reported outcomes of breast cancer patients undergoing postmastectomy autologous reconstruction to those who had breast implants, in terms of aesthetic appearance; levels of psychological, physical, and sexual well-being; and overall satisfaction. METHODS: Of 5063 women who underwent immediate reconstruction (n = 3349) or delayed reconstruction (n = 1714) between January 1, 2008, and March 31, 2009, in England, 2923 women who gave informed consent were sent validated, procedure-specific, 18-month follow-up questionnaires. Outcome scale scores ranged from 0 (poor) to 100 (excellent); multiple linear regression was used to adjust scores for patient and treatment characteristics. RESULTS: Two thousand two hundred eighty-nine women (78 percent) returned completed questionnaires (immediate reconstruction, n = 1528; delayed reconstruction, n = 761). For immediate reconstruction, mean overall satisfaction scores for the various techniques ranged from 67 to 85 (median, 67 to 93). For delayed reconstruction, mean overall satisfaction scores ranged from 70 to 85 (median, 75 to 100). For both groups, similar gradients were observed for the other outcome scales across techniques. Reconstruction using patients' own tissues tended to have higher mean adjusted scores compared with those techniques using implants alone (p < 0.0001 for aesthetic appearance, psychological well-being, sexual well-being, and satisfaction with outcomes for immediate and delayed reconstruction groups). CONCLUSIONS: Women who underwent autologous reconstruction tended to report greater satisfaction than those who underwent implant reconstruction. These results can inform patients of the anticipated outcomes of their selected surgery, but further research is required to confirm whether autologous reconstruction is superior in general. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

OBJECTIVE: To assess grommet insertion practice in the first 5 years of life among children with an orofacial cleft in England. DESIGN: Analysis of national administrative data of hospital admissions. SETTING: National Health Service hospitals, England. PATIENTS: Patients born between 1997 and 2005 who underwent surgical cleft repair. INTERVENTION: Children receiving grommets before the age of 5 years. OUTCOME MEASURES: The proportion of children receiving grommets before the age of 5 years, the timing of the first grommet insertion, and the proportion of children having repeat grommet insertions were examined according to cleft type, the absence or presence of additional anomalies, socioeconomic deprivation, and region of residence. RESULTS: The study included 8,269 children. Before the age of 5 years, 3,015 (36.5%) children received grommets. Of these, 33.2% received their first grommets at primary cleft repair and 33.3% underwent multiple grommet insertion procedures. The most common age for the first procedure was between 6 and 12 months. Children with a cleft affecting the palate were more likely to receive grommets than children with a cleft lip alone (45.5% versus 4.5%). Grommet insertion practice also varied according to year of birth, absence or presence of additional anomalies, socioeconomic deprivation, and region of residence. CONCLUSION: Grommets practice in children with a cleft appears to vary according to their clinical characteristics. The differences in practice observed according to deprivation and region of residence need to be further explored.

BACKGROUND: Concerns have been raised that a lack of senior obstetricians ("consultants") on the labour ward outside normal hours may lead to worse outcomes among babies born during periods of reduced cover. METHODS AND FINDINGS: We carried out a multicentre cohort study using data from 19 obstetric units in the United Kingdom between 1 April 2012 and 31 March 2013 to examine whether rates of obstetric intervention and outcome change "out-of-hours," i.e., when consultants are not providing dedicated, on-site labour ward cover. At the 19 hospitals, obstetric rotas ranged from 51 to 106 h of on-site labour ward cover per week. There were 87,501 singleton live births during the year, and 55.8% occurred out-of-hours. Women who delivered out-of-hours had slightly lower rates of intrapartum caesarean section (CS) (12.7% versus 13.4%, adjusted odds ratio [OR] 0.94; 95% confidence interval [CI] 0.90 to 0.98) and instrumental delivery (15.6% versus 17.0%, adj. OR 0.92; 95% CI 0.89 to 0.96) than women who delivered at times of on-site labour ward cover. There was some evidence that the severe perineal tear rate was reduced in out-of-hours vaginal deliveries (3.3% versus 3.6%, adj. OR 0.92; 95% CI 0.85 to 1.00). There was no evidence of a statistically significant difference between out-of-hours and "in-hours" deliveries in the rate of babies with a low Apgar score at 5 min (1.33% versus 1.25%, adjusted OR 1.07; 95% CI 0.95 to 1.21) or low cord pH (0.94% versus 0.82%; adjusted OR 1.12; 95% CI 0.96 to 1.31). Key study limitations include the potential for bias by indication, the reliance upon an organisational measure of consultant presence, and a non-random sample of maternity units. CONCLUSIONS: There was no difference in the rate of maternal and neonatal morbidity according to the presence of consultants on the labour ward, with the possible exception of a reduced rate of severe perineal tears in out-of-hours vaginal deliveries. Fewer women had operative deliveries out-of-hours. Taken together, the available evidence provides some reassurance that the current organisation of maternity care in the UK allows for good planning and risk management. However there is a need for more robust evidence on the quality of care afforded by different models of labour ward staffing.

BACKGROUND: There is a lack of evidence on the effectiveness or cost-effectiveness of alternative brands of prosthesis for total knee replacement (TKR). We compared patient-reported outcomes, revision rates, and costs, and estimated the relative cost-effectiveness of five frequently used cemented brands of unconstrained prostheses with fixed bearings (PFC Sigma, AGC Biomet, Nexgen, Genesis 2, and Triathlon). METHODS: We used data from three national databases for patients who had a TKR between 2003 and 2012, to estimate the effect of prosthesis brand on post-operative quality of life (QOL) (EQ-5D-3L) in 53 126 patients at six months. We compared TKR revision rates by brand over 10 years for 239 945 patients. We used a fully probabilistic Markov model to estimate lifetime costs and quality-adjusted life years (QALYs), incremental cost effectiveness ratios (ICERs), and the probability that each prosthesis brand is the most cost effective at alternative thresholds of willingness-to-pay for a QALY gain. FINDINGS: Revision rates were lowest with the Nexgen and PFC Sigma (2.5% after 10 years in 70-year-old women). Average lifetime costs were lowest with the AGC Biomet (£9 538); mean post-operative QOL was highest with the Nexgen, which was the most cost-effective brand across all patient subgroups. For example, for 70-year-old men and women, the ICERs for the Nexgen compared to the AGC Biomet were £2 300 per QALY. At realistic cost per QALY thresholds (£10 000 to £30 000), the probabilities that the Nexgen is the most cost-effective brand are about 98%. These results were robust to alternative modelling assumptions. CONCLUSIONS: AGC Biomet prostheses are the least costly cemented unconstrained fixed brand for TKR but Nexgen prostheses lead to improved patient outcomes, at low additional cost. These results suggest that Nexgen should be considered as a first choice prosthesis for patients with osteoarthritis who require a TKR.

OBJECTIVES: Prostate cancer mortality (PCM) in the USA is among the lowest in the world, whereas PCM in England is among the highest in Europe. This paper aims to assess the association of variation in use of definitive therapy on risk-adjusted PCM in England as compared with the USA. DESIGN: Observational study. SETTING: Cancer registry data from England and the USA. PARTICIPANTS: Men diagnosed with non-metastatic prostate cancer (PCa) in England and the USA between 2004 and 2008. OUTCOME MEASURES: Competing-risks survival analyses to estimate subhazard ratios (SHR) of PCM adjusted for age, ethnicity, year of diagnosis, Gleason score (GS) and clinical tumour (cT) stage. RESULTS: 222,163 men were eligible for inclusion. Compared with American patients, English patients were more likely to present at an older age (70-79â years: England 44.2%, USA 29.3%, p<0.001), with higher tumour stage (cT3-T4: England 25.1%, USA 8.6%, p<0.001) and higher GS (GS 8-10: England 20.7%, USA 11.2%, p<0.001). They were also less likely to receive definitive therapy (England 38%, USA 77%, p<0.001). English patients were more likely to die of PCa (SHR=1.9, 95% CI 1.7 to 2.0, p<0.001). However, this difference was no longer statistically significant when also adjusted for use of definitive therapy (SHR=1.0, 95% CI 1.0 to 1.1, p=0.3). CONCLUSIONS: Risk-adjusted PCM is significantly higher in England compared with the USA. This difference may be explained by less frequent use of definitive therapy in England.

OBJECTIVES: This paper summarises the findings of a national audit of mastectomy and breast reconstruction surgery carried out in England. It describes patterns of treatment, and the clinical and patient-reported quality of life outcomes associated with these types of procedure. DESIGN: Prospective cohort study. SETTING: All 150 National Health Service hospital groups (NHS trusts) in England that provided mastectomy or breast reconstruction surgery, along with six NHS trusts in Wales and Scotland and 114 independent hospitals. PARTICIPANTS: Women aged 16 years and over undergoing mastectomy with or without immediate breast reconstruction, or primary delayed breast reconstruction, between 1st January 2008 and 31st March 2009. MAIN OUTCOME MEASURES: Reconstructive utilisation, post-operative complications and sequelae, and patient-reported satisfaction and quality of life. RESULTS: Overall, 21% of the 16,485 women who had mastectomy underwent immediate reconstruction. However, the proportion varied between regions from 9% to 43% (p < 0.001). Levels of patient satisfaction with information, choice and the quality of care were high. The proportion of women who experienced local complications was 10.30% (95% CI 9.78-10.84) for mastectomy surgery, ranged from 11.02% (9.31-12.92) to 18.24% (14.80-22.10) for different immediate reconstructive procedures, and from 5.00% (2.76-8.25) to 19.86% (16.21-23.94) for types of delayed reconstruction. Breast appearance and overall well-being scores reported 18 months after surgery were higher among women having immediate breast reconstruction compared to mastectomy only. Postoperative outcomes were similar across providers.. CONCLUSIONS: The Audit found women were highly satisfied with their peri-operative care, with hospital providers achieving similar outcomes. English providers should examine how to reduce the variation in rates of immediate reconstruction.
