ABSTRACT
BACKGROUND: Prescribing of strong opioids and antibiotics impacts patient safety, yet little is known about the effects GP wellness has on overprescribing of both medications in primary care. AIM: To examine associations between strong opioid and antibiotic prescribing and practice-âweighted GP burnout and wellness. DESIGN AND SETTING: A retrospective cross-sectional study was undertaken using prescription data on strong opioids and antibiotics from the Oxford-âRoyal College of General Practitioners Research and Surveillance Centre linking to a GP wellbeing survey overlaying the same 4-month period from December 2019 to April 2020. METHOD: Patients prescribed strong opioids and antibiotics were the outcomes of interest. RESULTS: Data for 40 227 patients (13 483 strong opioids and 26 744 antibiotics) were linked to 57 practices and 351 GPs. Greater strong opioid prescribing was associated with increased emotional exhaustion (incidence risk ratio [IRR] 1.19, 95% confidence interval [CI] = 1.10 to 1.24), depersonalisation (IRR 1.10, 95% CI = 1.01 to 1.16), job dissatisfaction (IRR 1.25, 95% CI = 1.19 to 1.32), diagnostic uncertainty (IRR 1.12, 95% CI = 1.08 to 1.19), and turnover intention (IRR 1.32, 95% CI = 1.27 to 1.37) in GPs. Greater antibiotic prescribing was associated with increased emotional exhaustion (IRR 1.19, 95% CI = 1.05 to 1.37), depersonalisation (IRR 1.24, 95% CI = 1.08 to 1.49), job dissatisfaction (IRR 1.11, 95% CI = 1.04 to 1.19), sickness-presenteeism (IRR 1.18, 95% CI = 1.11 to 1.25), and turnover intention (IRR 1.38, 95% CI = 1.31 to 1.45) in GPs. Increased strong opioid and antibiotic prescribing was also found in GPs working longer hours (IRR 3.95, 95% CI = 3.39 to 4.61; IRR 5.02, 95% CI = 4.07 to 6.19, respectively) and in practices in the north of England (1.96, 95% CI = 1.61 to 2.33; 1.56, 95% CI = 1.12 to 3.70, respectively). CONCLUSION: This study found higher rates of prescribing of strong opioids and antibiotics in practices with GPs with more burnout symptoms, greater job dissatisfaction, and turnover intentions; working longer hours; and in practices in the north of England serving more deprived populations.

OBJECTIVE: English primary care faces significant challenges, including 'persistent high turnover' of general practitioners (GPs) in some partnerships. It is unknown whether there are specific predictors of persistent high turnover and whether it is associated with poorer population health outcomes. DESIGN: A retrospective observational study. METHODS: We linked workforce data on individual GPs to practice-level data from Hospital Episode Statistics and the GP Patient Survey (2007-2019). We classified practices as experiencing persistent high turnover if more than 10% of GPs changed in at least 3 consecutive years. We used multivariable logistic or linear regression models for panel data with random effects to identify practice characteristics that predicted persistent high turnover and associations of practice outcomes (higher emergency hospital use and patient experience of continuity of care, access to care and overall patient satisfaction) with persistent high turnover. RESULTS: Each year, 6% of English practices experienced persistent high turnover, with a maximum of 9% (688/7619) in 2014. Larger practices, in more deprived areas and with a higher morbidity burden were more likely to experience persistent high turnover. Persistent high turnover was associated with 1.8 (95% CI 1.5 to 2.1) more emergency hospital attendances per 100 patients, 0.1 (95% CI 0.1 to 0.2) more admissions per 100 patients, 5.2% (95% CI -5.6% to -4.9%) fewer people seeing their preferred doctor, 10.6% (95% CI-11.4% to -9.8%) fewer people reporting obtaining an appointment on the same day and 1.3% (95% CI -1.6% to -1.1%) lower overall satisfaction with the practice. CONCLUSIONS: Persistent high turnover is independently linked to indicators of poorer service and health outcomes. Although causality needs to be further investigated, strategies and policies may be needed to both reduce high turnover and support practices facing challenges with high GP turnover when it occurs.

OBJECTIVE: To examine the association of physician burnout with the career engagement and the quality of patient care globally. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, PsycINFO, Embase, and CINAHL were searched from database inception until May 2021. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Observational studies assessing the association of physician burnout (including a feeling of overwhelming emotional exhaustion, feelings of cynicism and detachment from job defined as depersonalisation, and a sense of ineffectiveness and little personal accomplishment) with career engagement (job satisfaction, career choice regret, turnover intention, career development, and productivity loss) and the quality of patient care (patient safety incidents, low professionalism, and patient satisfaction). Data were double extracted by independent reviewers and checked through contacting all authors, 84 (49%) of 170 of whom confirmed their data. Random-effect models were used to calculate the pooled odds ratio, prediction intervals expressed the amount of heterogeneity, and meta-regressions assessed for potential moderators with significance set using a conservative level of P<0.10. RESULTS: 4732 articles were identified, of which 170 observational studies of 239 246 physicians were included in the meta-analysis. Overall burnout in physicians was associated with an almost four times decrease in job satisfaction compared with increased job satisfaction (odds ratio 3.79, 95% confidence interval 3.24 to 4.43, I2=97%, k=73 studies, n=146 980 physicians). Career choice regret increased by more than threefold compared with being satisfied with their career choice (3.49, 2.43 to 5.00, I2=97%, k=16, n=33 871). Turnover intention also increased by more than threefold compared with retention (3.10, 2.30 to 4.17, I2=97%, k=25, n=32 271). Productivity had a small but significant effect (1.82, 1.08 to 3.07, I2=83%, k=7, n=9581) and burnout also affected career development from a pooled association of two studies (3.77, 2.77 to 5.14, I2=0%, n=3411). Overall physician burnout doubled patient safety incidents compared with no patient safety incidents (2.04, 1.69 to 2.45, I2=87%, k=35, n=41 059). Low professionalism was twice as likely compared with maintained professionalism (2.33, 1.96 to 2.70, I2=96%, k=40, n=32 321), as was patient dissatisfaction compared with patient satisfaction (2.22, 1.38 to 3.57, I2=75%, k=8, n=1002). Burnout and poorer job satisfaction was greatest in hospital settings (1.88, 0.91 to 3.86, P=0.09), physicians aged 31-50 years (2.41, 1.02 to 5.64, P=0.04), and working in emergency medicine and intensive care (2.16, 0.98 to 4.76, P=0.06); burnout was lowest in general practitioners (0.16, 0.03 to 0.88, P=0.04). However, these associations did not remain significant in the multivariable regressions. Burnout and patient safety incidents were greatest in physicians aged 20-30 years (1.88, 1.07 to 3.29, P=0.03), and people working in emergency medicine (2.10, 1.09 to 3.56, P=0.02). The association of burnout with low professionalism was smallest in physicians older than 50 years (0.36, 0.19 to 0.69, P=0.003) and greatest in physicians still in training or residency (2.27, 1.45 to 3.60, P=0.001), in those who worked in a hospital (2.16, 1.46 to 3.19, P<0.001), specifically in emergency medicine specialty (1.48, 1.01 to 2.34, P=0.042), or situated in a low to middle income country (1.68, 0.94 to 2.97, P=0.08). CONCLUSIONS: This meta-analysis provides compelling evidence that physician burnout is associated with poor function and sustainability of healthcare organisations primarily by contributing to the career disengagement and turnover of physicians and secondarily by reducing the quality of patient care. Healthcare organisations should invest more time and effort in implementing evidence-based strategies to mitigate physician burnout across specialties, and particularly in emergency medicine and for physicians in training or residency.

Background: General Practitioners (GPs) report high levels of burnout, job dissatisfaction, and turnover intention. The complexity of presenting problems to general practice makes diagnostic uncertainty a common occurrence that has been linked to burnout. The interrelationship between diagnostic uncertainty with other factors such as burnout, job satisfaction and turnover intention have not been previously examined. Objectives: To examine associations between diagnostic uncertainty, emotional exhaustion (EE), depersonalization (DP), job satisfaction, and turnover intention in GPs. Methods: Seventy general practices in England were randomly selected through the Oxford-Royal College of General Practitioners Research and Surveillance Centre (RCGP-RSC). A total of 348 GPs within 67 these practices completed a 10-item online questionnaire which included questions on GP characteristics, work-life balance, job satisfaction, sickness presenteeism, diagnostic uncertainty, turnover intention as well as EE and DP. Associations between diagnostic uncertainty and each of EE, DP, job satisfaction, and turnover intention were evaluated in multivariate mixed-effect ordinal logistic regressions whilst adjusting for covariates, to account for the correlation in the three outcomes of interest. Results: Almost one-third of GPs (n = 101; 29%) reported experiencing >10% of diagnostic uncertainty in their day-to-day practice over the past year. GPs reporting greater diagnostic uncertainty had higher levels of EE [OR = 3.90; 95% CI = (2.54, 5.99)], job dissatisfaction [OR = 2.01; 95% CI = (1.30, 3.13)] and turnover intention [OR = 4.51; 95% CI = (2.86, 7.11)]. GPs with no sickness presenteeism had lower levels of EE [OR = 0.53; 95% CI = (0.35, 0.82)], job dissatisfaction [OR = 0.56; 95% CI = (0.35, 0.88)], and turnover intention [OR = 0.61; 95% CI = (0.41, 0.91)]. Conclusion: Diagnostic uncertainty may not only negatively impact on the wellbeing of GPs, but could also have adverse implications on workforce retention in primary care.
ABSTRACT
OBJECTIVE: The authors examined associations between stressors and burnout in trainee doctors during the COVID-19 pandemic. METHODS: An anonymous online questionnaire including 42 questions on general and pandemic-specific stressors, and the Maslach Burnout Inventory-Health Services Survey (MBI-HSS), was sent to 1000 randomly selected trainee doctors in North-West England. Main outcomes were burnout scores that were stratified into Emotional Exhaustion (EE), Depersonalisation (DP), and reduced Personal Accomplishment (PA) and associations between stressors and burnout using stepwise regression analysis. RESULTS: A total of 362 complete responses were received giving a response rate of 37%. Mean scores for EE, DP, and PA derived from the MBI-HSS were 27.7, 9.8, and 34.3 respectively. Twenty-three stressors were found to be associated with burnout dimensions. "Increase in workload and hours due to COVID-19," "Poor leadership and management in the National Health Service," and "Not feeling valued" were found to have strong associations with burnout dimensions. Only "Not confident in own abilities" was found to be associated with all burnout dimensions. CONCLUSIONS: Associations with burnout were found to be identified in a range of work, pandemic, and non-work-related stressors, supporting the need for multi-level interventions to mitigate burnout.

OBJECTIVES: This study aims to develop a comprehensive list of stressors relevant to junior doctors and will also report findings exploring the associations between burnout and stressors, which include work and non-work-related stressors as well as pandemic-related stressors. METHODS: An anonymous online questionnaire was sent to 1000 randomly selected junior doctors in the North-West of England. The questionnaire included 37 questions on general and pandemic-specific stressors, and the Maslach Burnout Inventory Health Services Survey. The main outcomes of interest were junior doctor ratings of stressors and scores for burnout (emotional exhaustion [EE], depersonalisation [DP], and personal accomplishment [PA]). Stepwise regression analysis was undertaken to assess associations between stressors and burnout. RESULTS: In total, 326 responses were collected (response rate = 33%). Of the top 10 stressors rated by junior doctors, 60% were related to the pandemic. Multiple stressors were found to be associated with the burnout dimensions. Fatigue (ß = .43), pandemic-related workload increase (ß = .33), and feeling isolated (ß = .24) had the strongest associations with EE, whereas fatigue (ß = .21), uncertainty around COVID-19 information (ß = .22) and doing unproductive tasks (ß = .17) had the strongest associations with DP. Working beyond normal scope due to COVID-19 (ß = -.26), not confident in own ability (ß = -.24) and not feeling valued (ß = -.20) were found to have the strongest associations with PA. CONCLUSIONS: Junior doctors experience a combination of general stressors and additional stressors emerging from the pandemic which significantly impact burnout. Monitoring these stressors and targeting them as part of interventions could help mitigating burnout in junior doctors.

OBJECTIVE: To describe the distribution of consultations at the practice level and examine whether increases are uniform or driven by people who consult more frequently. DESIGN: Retrospective cohort study. SETTING: UK general practice data from the Clinical Practice Research Datalink (CPRD) GOLD database. PARTICIPANTS: 1 699 709 314 consultation events from 12 330 545 patients, in 845 general practices (1 April 2000 to 31 March 2019). METHODS: Consultation information was aggregated by financial year into: all consultations/all staff; all consultations/general practitioners (GPs); face-to-face consultations/all staff; face-to-face consultations/GPs. Patients with a number of consultations above the 90th centile, within each year, were classified as frequent attenders. Negative binomial regressions examined the association between available practice characteristics and consultation distribution. RESULTS: Among frequent attenders, all consultations by GPs increased from a median (25th and 75th centile) of 13 (10 and 16) to 21 (18 and 25) and all consultations by all staff increased from 27 (23-30) to 60 (51-69) over the study period. Approximately four out of ten consultations of any type concerned frequent attenders and the proportion of consultations attributed to them increased over time, particularly for face-to-face consultations with GPs, from a median of 38.0% (35.9%-40.3%) in 2000-2001 to 43.0% (40.6%-46.4%) in 2018-2019. Regression analyses indicated decreasing trends over time for face-to-face consultations and increasing trends for all consultation types, for both GPs and all staff. Frequent attenders consulted approximately five times more than the rest of the practice population, on average, with adjusted incidence rate ratios ranging between 4.992 (95% CI 4.917 to 5.068) for face-to-face consultations with all staff and 5.603 (95% CI 5.560 to 5.647) for all consultations with GPs. CONCLUSIONS: Frequent attenders progressively contributed to increased workload in general practices across the UK from 2000 to 2019. Important knowledge gaps remain in terms of the demographic, social and health characteristics of frequent attenders and how UK general practices can be prepared to meet the needs of these patients.

OBJECTIVE: To quantify general practitioners' (GPs') turnover in England between 2007 and 2019, describe trends over time, regional differences and associations with social deprivation or other practice characteristics. DESIGN: A retrospective study of annual cross-sectional data. SETTING: All general practices in England (8085 in 2007, 6598 in 2019). METHODS: We calculated turnover rates, defined as the proportion of GPs leaving a practice. Rates and their median, 25th and 75th percentiles were calculated by year and region. The proportion of practices with persistent high turnover (>10%) over consecutive years were also calculated. A negative binomial regression model assessed the association between turnover and social deprivation or other practice characteristics. RESULTS: Turnover rates increased over time. The 75th percentile in 2009 was 11%, but increased to 14% in 2019. The highest turnover rate was observed in 2013-2014, corresponding to the 75th percentile of 18.2%. Over time, regions experienced increases in turnover rates, although it varied across English regions. The proportion of practices with high (10% to 40%) turnover within a year almost doubled from 14% in 2009 to 27% in 2019. A rise in the number of practices with persistent high turnover (>10%) for at least three consecutive years was also observed, from 2.7% (2.3%-3.1%) in 2007 to 6.3% (5.7%-6.9%) in 2017. The statistical analyses revealed that practice-area deprivation was moderately associated with turnover rate, with practices in the most deprived area having higher turnover rates compared with practices in the least deprived areas (incidence rate ratios 1.09; 95% CI 1.06 to 1.13). CONCLUSIONS: GP turnover has increased in the last decade nationally, with regional variability. Greater attention to GP turnover is needed, in the most deprived areas in particular, where GPs often need to deal with more complex health needs. There is a large cost associated with GP turnover and practices with very high persistent turnover need to be further researched, and the causes behind this identified, to allow support strategies and policies to be developed.

BACKGROUND: Diagnostic error is a global patient safety priority. OBJECTIVES: To estimate the incidence, origins and avoidable harm of diagnostic errors in English general practice. Diagnostic errors were defined as missed opportunities to make a correct or timely diagnosis based on the evidence available (missed diagnostic opportunities, MDOs). METHOD: Retrospective medical record reviews identified MDOs in 21 general practices. In each practice, two trained general practitioner reviewers independently conducted case note reviews on 100 randomly selected adult consultations performed during 2013-2014. Consultations where either reviewer identified an MDO were jointly reviewed. RESULTS: Across 2057 unique consultations, reviewers agreed that an MDO was possible, likely or certain in 89 cases or 4.3% (95% CI 3.6% to 5.2%) of reviewed consultations. Inter-reviewer agreement was higher than most comparable studies (Fleiss' kappa=0.63). Sixty-four MDOs (72%) had two or more contributing process breakdowns. Breakdowns involved problems in the patient-practitioner encounter such as history taking, examination or ordering tests (main or secondary factor in 61 (68%) cases), performance and interpretation of diagnostic tests (31; 35%) and follow-up and tracking of diagnostic information (43; 48%). 37% of MDOs were rated as resulting in moderate to severe avoidable patient harm. CONCLUSIONS: Although MDOs occurred in fewer than 5% of the investigated consultations, the high numbers of primary care contacts nationally suggest that several million patients are potentially at risk of avoidable harm from MDOs each year. Causes of MDOs were frequently multifactorial, suggesting the need for development and evaluation of multipronged interventions, along with policy changes to support them.

BACKGROUND: Despite growing positive evidence supporting the potential utility of differential diagnostic generator (DDX) tools, uptake has been limited in terms of geography and settings and calls have been made to test such tools in wider routine clinical settings. This study aims to evaluate the feasibility and utility of clinical use of Isabel, an electronic DDX tool, in a United Kingdom (UK) general practice setting. METHODS: Mixed methods. Feasibility and utility were assessed prospectively over a 6-month period via: usage statistics, survey as well as interview data generated from clinicians before and after Isabel was available for clinical use. Normalisation process theory (NPT) was utilised as a sensitising concept in the data collection and analysis of the qualitative data. RESULTS: Usage was extremely limited (n = 18 searches). Most potential users did not utilise the program and of those that did (n = 6), usage was restricted and did not alter subsequent patient management. Baseline interview findings indicated some prior awareness of DDX tools and ambivalent views with regards to potential utility. Post-use interviews supported analytic data and indicated low usage due to a range of endogenous (professional) and exogenous (organisational) factors. CONCLUSIONS: In its current form, this small exploratory study suggests that Isabel is a tool that is unlikely to be utilised on a routine basis in primary care, but may have potential utility for diagnostic support in (1) education/training and (2) rare and diagnostically complex cases.

This short report aims to investigate the association between teamwork and burnout among general practitioners (GPs). A two-stage survey was conducted. In stage one, validated self-report measures of burnout and teamwork were completed by 50 GPs across 12 general practices in Greater Manchester, UK. In stage two, staff members across 3 of the 12 general practices (GPs, nursing staff, managers and admin staff) responded to free text questions about teamwork (n = 20). The results of the stage one survey showed that teamwork in GPs was significantly negatively associated with the emotional exhaustion (r = -0.326, P < 0.05) and depersonalization (r = -0.421, P < 0.01) domains of the burnout measure and significantly positively associated with the personal accomplishment (r = 0.296, P < 0.05) domain. Free text responses in stage two were assigned into three themes: (i) addressing organizational barriers which might threaten teamwork, (ii) promoting the view of teamwork as a shared responsibility among all staff members of the general practice and (iii) implementing improvement strategies which can be embedded in the busy environment of general practices. GPs and other staff members of general practices valued the importance of teamwork for boosting their morale and mitigating burnout. Future research should focus on designing and embedding brief teamwork improvement strategies in general practices.

Importance: Evidence suggests that physicians experience high levels of burnout and stress and that trainee physicians are a particularly high-risk group. Multiple workplace- and non-workplace-related factors have been identified in trainee physicians, but it is unclear which factors are most important in association with burnout and stress. Better understanding of the most critical factors could help inform the development of targeted interventions to reduce burnout and stress. Objective: To estimate the association between different stressors and burnout/stress among physicians engaged in standard postgraduate training (ie, trainee physicians). Data Sources: Medline, Embase, PsycINFO, and Cochrane Database of Systematic reviews from inception until April 30, 2019. Search terms included trainee, foundation year, registrar, resident, and intern. Study Selection: Studies that reported associations between stressors and burnout/stress in trainee physicians. Data Extraction and Synthesis: Two independent reviewers extracted the data and assessed the quality of the evidence. The main meta-analysis was followed by sensitivity analyses. All analyses were performed using random-effects models, and heterogeneity was quantified using the I2 statistic. Main Outcome and Measures: The main outcome was the association between burnout/stress and workplace- or non-workplace-related factors reported as odds ratios (ORs) and their 95% CIs. Results: Forty-eight studies were included in the meta-analysis (n = 36 266, median age, 29 years [range, 24.6-35.7 years]). One study did not specify participants' sex; of the total population, 18â¯781 participants (52%) were men. In particular, work demands of a trainee physician were associated with a nearly 3-fold increased odds for burnout/stress (OR, 2.84; 95% CI, 2.26-3.59), followed by concerns about patient care (OR, 2.35; 95% CI, 1.58-3.50), poor work environment (OR, 2.06; 95% CI, 1.57-2.70), and poor work-life balance (OR, 1.93; 95% CI, 1.53-2.44). Perceived/reported poor mental or physical health (OR, 2.41; 95% CI, 1.76-3.31), female sex (OR, 1.34; 95% CI, 1.20-1.50), financial worries (OR, 1.35; 95% CI, 1.07-1.72), and low self-efficacy (OR, 2.13; 95% CI, 1.31-3.46) were associated with increased odds for burnout/stress, whereas younger age and a more junior grade were not significantly associated. Conclusions and Relevance: The findings of this study suggest that the odds ratios for burnout and stress in trainee physicians are higher than those for work-related factors compared with nonmodifiable and non-work-related factors, such as age and grade. These findings support the need for organizational interventions to mitigate burnout in trainee physicians.

OBJECTIVE: To evaluate the effects of a computerised decision support tool for comprehensive drug review in elderly people with polypharmacy. DESIGN: Pragmatic, multicentre, cluster randomised controlled trial. SETTING: 359 general practices in Austria, Germany, Italy, and the United Kingdom. PARTICIPANTS: 3904 adults aged 75 years and older using eight or more drugs on a regular basis, recruited by their general practitioner. INTERVENTION: A newly developed electronic decision support tool comprising a comprehensive drug review to support general practitioners in deprescribing potentially inappropriate and non-evidence based drugs. Doctors were randomly allocated to either the electronic decision support tool or to provide treatment as usual. MAIN OUTCOME MEASURES: The primary outcome was the composite of unplanned hospital admission or death by 24 months. The key secondary outcome was reduction in the number of drugs. RESULTS: 3904 adults were enrolled between January and October 2015. 181 practices and 1953 participants were assigned to electronic decision support (intervention group) and 178 practices and 1951 participants to treatment as usual (control group). The primary outcome (composite of unplanned hospital admission or death by 24 months) occurred in 871 (44.6%) participants in the intervention group and 944 (48.4%) in the control group. In an intention-to-treat analysis the odds ratio of the composite outcome was 0.88 (95% confidence interval 0.73 to 1.07; P=0.19, 997 of 1953 v 1055 of 1951). In an analysis restricted to participants attending practice according to protocol, a difference was found favouring the intervention (odds ratio 0.82, 95% confidence interval 0.68 to 0.98; 774 of 1682 v 873 of 1712, P=0.03). By 24 months the number of prescribed drugs had decreased in the intervention group compared with control group (uncontrolled mean change -0.42 v 0.06: adjusted mean difference -0.45, 95% confidence interval -0.63 to -0.26; P<0.001). CONCLUSIONS: In intention-to-treat analysis, a computerised decision support tool for comprehensive drug review of elderly people with polypharmacy showed no conclusive effects on the composite of unplanned hospital admission or death by 24 months. Nonetheless, a reduction in drugs was achieved without detriment to patient outcomes. TRIAL REGISTRATION: Current Controlled Trials ISRCTN10137559.
