Associations between corporate ownership of primary care providers and doctor wellbeing, workload, access, organizational efficiency, and service quality.

Traditionally, in many countries general practices have been privately-owned independent small businesses. However, the last three decades has seen the rise of large corporate medical groups defined as private companies which are able to have non-GP shareholders and with branches across many locations. The greater prominence of profit motives may have implications for costs, access to care and quality of care. We estimate that 45% of GPs in Australia worked in a practice that was a private company, and within this group over one third (19.9% of total) worked in a corporate medical group (a private company with 10 or more practice locations). We examine the association between being in a corporate medical group and 19 outcomes classified into five groups: GP wellbeing, workload, patient access, organizational efficiency, and service quality. GPs who worked in such groups were more likely to be older, qualified overseas, and to have a conscientious personality. There was mixed evidence on GPs wellbeing, with GPs in corporate medical groups reporting a higher turnover of GPs but similar levels of job satisfaction. GP workload was similar in terms of hours worked and after hours work but they reported a lower work-life balance. Patient access was better in terms of lower fees charged to patients but there was weak evidence that patients waited longer. GPs in corporate medical groups reported higher organisational efficiency because GPs spent less time spent on administration and management, had more nurses per GP, but despite this GPs were more likely to undertake tasks someone less qualified could do suggesting that nurses were complements not substitutes. There were no differences in service quality (teaching, patient complaints, consultation length, patients seen per hour). Corporate medical groups have become a substantial part of primary care provision in Australia. There is evidence they are more efficient, patient access is better with lower out of pocket costs and there are no differences in our measures service quality, but concerns remain about GP's wellbeing and work-life balance. Further research is needed on continuity of care and patient reported experiences and health outcomes.

Class II HLA-DRB4 is a predictive biomarker for survival following immunotherapy in metastatic non-small cell lung cancer.

Immune checkpoint inhibitors (ICI) are important treatment options for metastatic non-small cell lung cancer (mNSCLC). However, not all patients benefit from ICIs and can experience immune-related adverse events (irAEs). Limited understanding exists for germline determinants of ICI efficacy and toxicity, but Human Leukocyte Antigen (HLA) genes have emerged as a potential predictive biomarker. We performed HLA typing on 85 patients with mNSCLC, on ICI therapy and analyzed the impact of HLA Class II genotype on progression free survival (PFS), overall survival (OS), and irAEs. Most patients received pembrolizumab (83.5%). HLA-DRB4 genotype was seen in 34/85 (40%) and its presence correlated with improved OS in both univariate (p = 0.022; 26.3 months vs 10.2 months) and multivariate analysis (p = 0.011, HR 0.49, 95% CI [0.29, 0.85]). PFS did not reach significance (univariate, p = 0.12, 8.2 months vs 5.1 months). Eleven patients developed endocrine irAEs. HLA-DRB4 was the predominant genotype among these patients (9/11, 81.8%). Cumulative incidence of endocrine irAEs was higher in patients with HLA-DRB4 (p = 0.0139). Our study is the first to suggest that patients with metastatic NSCLC patients on ICI therapy with HLA-DRB4 genotype experience improved survival outcomes. Patients with HLA-DRB4 had the longest median OS (26.3 months). Additionally, we found a correlation between HLA-DRB4 and the occurrence of endocrine irAEs.

The hidden impact of alcohol on young victims: an analysis of alcohol-related police offences resulting in hospitalisation.

BACKGROUND: Alcohol-related harm (ARH) is a significant public health concern affecting young individuals, particularly those involved in alcohol-related police incidents resulting in hospitalisation. However, the impact of alcohol on young victims remains under researched. This study aimed to identify the characteristics of offenders and victims involved in these incidents, analyse the types of offences, and understand the under-ascertainment of ARH in hospital records. METHODS: A retrospective longitudinal study of 12-24-year-olds born between 1980 and 2005 was conducted using linked data from hospital admissions, emergency department presentations, and police incident records. Alcohol-related incidents were identified based on the attending officers' opinions in the Western Australia Police's Incident Management System (IMS). Logistic and log-binomial regression were utilised to analyse the factors associated with victimisation and under-ascertainment of ARH. RESULTS: Our study included 22,747 individuals (11,433 victims and 11,314 offenders) involved in alcohol-related police incidents, with a small majority of victims being female (53%, n = 6,074) and a large majority of offenders being male (84.3%, n = 9,532). Most victims did not receive a diagnosis of ARH (71%, n = 760). Women were 10 times more likely to have been a victim in ARH police incidents and 2 times more likely to have an undiagnosed alcohol-related hospital admission than men. Victims and offenders predominantly came from disadvantaged areas and major cities. Aboriginal individuals were overrepresented as both offenders and victims. A significant proportion of individuals experienced emergency department presentations or hospital admissions, with head injuries being the most common. Assault causing bodily harm was the most prevalent offence resulting in hospitalisation (66%, n = 2,018). CONCLUSIONS: There is a noteworthy disparity between the quantity of hospital admissions attributed to alcohol-related incidents and the number of cases that are formally classified as ARH in the hospital system. This disparity highlights a more profound issue of substantial under-ascertainment or inadequate identification of ARH than previously acknowledged. Our findings justify the prioritisation of prevention strategies, beyond improvement in the documentation of alcohol-related hospitalisation. Considering the scale of the problem, and the underestimation of the burden of alcohol-related hospitalisation, a proportional increase in investment is necessary to achieve population-level reductions in ARH.

"It's not a one operation fits all": A qualitative study exploring fee setting and participation in price transparency initiatives amongst medical specialists in the Australian private healthcare sector.

The Australian government, through Medicare, defines the type of medical specialist services it covers and subsidizes, but it does not regulate prices. Specialists in private practice can charge more than the fee listed by Medicare depending on what they feel 'the market will bear'. This can sometimes result in high and unexpected out-of-pocket (OOP) payments for patients. To reduce pricing uncertainty and 'bill shock' faced by consumers, the government introduced a price transparency website in December 2019. It is not clear how effective such a website will be and whether specialists and patients will use it. The aim of this qualitative study was to explore factors influencing how specialists set their fees, and their views on and participation in price transparency initiatives. We conducted 27 semi-structured interviews with surgical specialists. We analysed the data using thematic analysis and responses were mapped to the Theoretical Domains Framework and the Capability, Opportunity, Motivation and Behavior model. We identified several patient, specialist and system-level factors influencing fee setting. Patient-level factors included patient characteristics, circumstance, complexity, and assumptions regarding perceived value of care. Specialist-level factors included perceived experience and skills, ethical considerations, and gendered-behavior. System-level factors included the Australian Medical Association recommended price list, practice costs, and supply and demand factors including perceived competition and practice location. Specialists were opposed to price transparency websites and lacked motivation to participate because of the complexity of fee setting, concerns over unintended consequences, and feelings of frustration they were being singled out. If price transparency websites are to be pursued, specialists' lack of motivation to participate needs to be addressed.

The stability of physicians' risk attitudes across time and domains.

Risk attitude is known to influence physicians' decision-making under uncertainty. Research on the risk attitudes of physicians is therefore important in facilitating a better understanding of physicians' decisions. However, little is known about the stability of physicians' risk attitudes across domains. Using five waves of data from a prospective panel study of Australian physicians from 2013 to 2017, we explored the stability of risk attitudes over a four-year period and examined the association between negative life events and risk attitudes among 4417 physicians. Further, we tested the stability of risk attitude across three domains most relevant to a physician's career and clinical decision-making (financial, career and clinical). The results showed that risk attitude was stable over time at both the mean and individual levels but the correlation between domains was modest. There were no significant associations between negative life events and risk attitude changes in all three domains. These findings suggest that risk attitude can be assumed to be constant but domain-specificity needs to be considered in analyses of physician decision-making.

The impact of changes in a physician fee schedule on medical expenditures, fees, and volume of services. Evidence from a national fee schedule reform in Australia.

We examine the impact of changes to a national physician fee schedule on total medical expenditures, the volume of services, and fees charged. In our context, changes to the fee schedule were designed to promote value-based health care, and so included different types of changes to subsidised medical services, including changes to fees. Using claims data from a sample of doctors linked to a physician survey, we use difference-in-difference methods with a staggered adoption design to compare medical services which were affected with those which were not. We show that medical expenditures and the volume of affected services fell, though there is uncertainty about the magnitude of the fall. For GPs, we find evidence of increases in expenditures and fees and an increase in fees for some services provided by specialists.

Stillbirths and Neonatal Deaths Caused by Group B Streptococcus in Africa and South Asia Identified Through Child Health and Mortality Prevention Surveillance (CHAMPS).

Background: Invasive Group B Streptococcus (GBS) is a common cause of early-onset neonatal sepsis and is also associated with stillbirth. This study aimed to determine the proportion of stillborn infants and infants who died between 0 and 90 days attributable to GBS using postmortem minimally invasive tissue sampling (MITS) in 7 low- and middle-income countries (LMICs) participating in Child Health and Mortality Prevention Surveillance (CHAMPS). Methods: Deaths that occurred between December 2016 and December 2021 were investigated with MITS, including culture for bacteria of blood and cerebrospinal fluid (CSF), multipathogen polymerase chain reaction on blood, CSF, and lung tissue and histopathology of lung, liver, and brain. Data collection included clinical record review and verbal autopsy. Expert panels reviewed all information and assigned causes of death. Results: We evaluated 2966 deaths, including stillborn infants (n = 1322), infants who died during first day of life (0 to <24 hours, n = 597), early neonatal deaths (END) (1 day to <7 days; END; n = 593), and deaths from 7 to 90 days (n = 454). Group B Streptococcus was determined to be in the causal pathway of death for 2.7% of infants (79 of 2, 966; range, 0.3% in Sierra Leone to 7.2% in South Africa), including 2.3% (31 of 1322) of stillbirths, 4.7% (28 of 597) 0 to <24 hours, 1.9% (11 of 593) END, and 2.0% (9 of 454) of deaths from 7 to 90 days of age. Among deaths attributed to GBS with birth weight data available, 61.9% (39 of 63) of decedents weighed <2500 grams at birth. Group B Streptococcus sepsis was the postmortem diagnosis for 100% (31 of 31) of stillbirths. For deaths <90 days, postmortem diagnoses included GBS sepsis (83.3%, 40 of 48), GBS meningitis (4.2%, 2 of 48), and GBS pneumonia (2.1%, 1 of 48). Conclusions: Our study reveals significant heterogeneity in the contribution of invasive GBS disease to infant mortality across different countries, emphasizing the need for tailored prevention strategies. Moreover, our findings highlight the substantial impact of GBS on stillbirths, shedding light on a previously underestimated aspect in LMICs.

A randomised controlled trial of email versus mailed invitation letter in a national longitudinal survey of physicians.

Despite their low cost, the use of email invitations to distribute surveys to medical practitioners have been associated with lower response rates. This research compares the difference in response rates from using email approach plus online completion rather than a mailed invitation letter plus a choice of online or paper completion. A parallel randomised controlled trial was conducted during the 11th annual wave of the nationally representative Medicine in Australia: Balancing Employment and Life (MABEL) longitudinal survey of doctors. The control group was invited using a mailed paper letter (including a paper survey plus instructions to complete online) and three mailed paper reminders. The intervention group was approached in the same way apart from the second reminder when they were approached by email only. The primary outcome is the response rate and the statistical analysis was blinded. 18,247 doctors were randomly allocated to the control (9,125) or intervention group (9,127), with 9,108 and 9,107 included in the analysis. Using intention to treat analysis, the response rate in the intervention group was 35.92% compared to 37.59% in the control group, a difference of -1.66 percentage points (95% CI: -3.06 to -0.26). The difference was larger for General Practitioners (-2.76 percentage points, 95% CI: -4.65 to -0.87) compared to other specialists (-0.47 percentage points, 95% CI: -2.53 to 1.60). For those who supplied an email address, the average treatment effect on the treated was higher at -2.63 percentage points (95% CI: -4.50 to -0.75) for all physicians, -3.17 percentage points (95% CI: -5.83 to -0.53) for General Practitioners, and -2.1 percentage points (95% CI: -4.75 to 0.56) for other specialists. For qualified physicians, using email to invite participants to complete a survey leads to lower response rates compared to a mailed letter. Lower response rates need to be traded off with the lower costs of using email rather than mailed letters.

Pathologic Tumor Size versus Mammography, Sonography, and MRI in Breast Cancer Based on Pathologic Subtypes.

INTRODUCTION: The standard of care for imaging of breast pathology has historically been mammography and sonography. MRI is a modern adjunct in the surgeon's toolkit. We looked to examine the differences in imaging modalities and their ability to predict the size in relation to the pathologic size after excision with focus on pathologic subtypes. METHODS: We analyzed patient records across a 4-year period from 2017 to 2021 who were treated surgically for breast cancer at our facility. We used a retrospective chart review to collect measurements that were recorded of the tumors by the radiologist for available mammography, ultrasound, and MRI which were compared to pathology report measurements of the final specimens. We subdivided the results by pathologic subtypes including invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), and ductal carcinoma in situ (DCIS). RESULTS: 658 total patients met criteria for analysis. Mammography overestimated specimens with DCIS by 1.93 mm (P = .15), US underestimated by .56 (.55), and MRI overestimated by 5.77 mm (P < .01). There was no statistically significant difference in any modalities with IDC. With specimens of ILC, all 3 imaging modalities underestimated tumor size, with only US being significant. DISCUSSION: Mammography and MRI consistently overestimated tumor size with the exception of ILC while US underestimated tumor size on all pathologic subtypes. MRI significantly overestimated tumor size in DCIS by 5.77 mm. Mammography was the most accurate imaging modality for all pathologic subtypes and never had a statistically significant difference from actual tumor size.

Does doctors' personality differ from those of patients, the highly educated and other caring professions? An observational study using two nationally representative Australian surveys.

OBJECTIVES: Personality differences between doctors and patients can affect treatment outcomes. We examine these trait disparities, as well as differences across medical specialities. DESIGN: Retrospective, observational statistical analysis of secondary data. SETTING: Data from two data sets that are nationally representative of doctors and the general population in Australia. PARTICIPANTS: We include 23 358 individuals from a representative survey of the general Australian population (with subgroups of 18 705 patients, 1261 highly educated individuals and 5814 working in caring professions) as well as 19 351 doctors from a representative survey of doctors in Australia (with subgroups of 5844 general practitioners, 1776 person-oriented specialists and 3245 technique-oriented specialists). MAIN OUTCOME MEASURES: Big Five personality traits and locus of control. Measures are standardised by gender, age and being born overseas and weighted to be representative of their population. RESULTS: Doctors are significantly more agreeable (a: standardised score -0.12, 95% CIs -0.18 to -0.06), conscientious (c: -0.27 to -0.33 to -0.20), extroverted (e: 0.11, 0.04 to 0.17) and neurotic (n: 0.14, CI 0.08 to 0.20) than the general population (a: -0.38 to -0.42 to -0.34, c: -0.96 to -1.00 to -0.91, e: -0.22 to -0.26 to -0.19, n: -1.01 to -1.03 to -0.98) or patients (a: -0.77 to -0.85 to -0.69, c: -1.27 to -1.36 to -1.19, e: -0.24 to -0.31 to -0.18, n: -0.71 to -0.76 to -0.66). Patients (-0.03 to -0.10 to 0.05) are more open than doctors (-0.30 to -0.36 to -0.23). Doctors have a significantly more external locus of control (0.06, 0.00 to 0.13) than the general population (-0.10 to -0.13 to -0.06) but do not differ from patients (-0.04 to -0.11 to 0.03). There are minor differences in personality traits among doctors with different specialities. CONCLUSIONS: Several personality traits differ between doctors, the population and patients. Awareness about differences can improve doctor-patient communication and allow patients to understand and comply with treatment recommendations.

Updating a clinical Knowledge-Based Planning prediction model for prostate radiotherapy.

BACKGROUND AND PURPOSE: Clinical knowledge-based planning (KBP) models dedicated to prostate radiotherapy treatment may require periodical updates to remain relevant and to adapt to possible changes in the clinic. This study proposes a paired comparison of two different update approaches through a longitudinal analysis. MATERIALS AND METHODS: A clinically validated KBP model for moderately hypofractionated prostate therapy was periodically updated using two approaches: one was targeted at achieving the biggest library size (Mt), while the other one at achieving the highest mean sample quality (Rt). Four subsequent updates were accomplished. The goodness, robustness and quality of the outcomes were measured and compared to those of the common ancestor. Plan quality was assessed through the Plan Quality Metric (PQM) and plan complexity was monitored. RESULTS: Both update procedures allowed for an increase in the OARs sparing between +3.9 % and +19.2 % compared to plans generated by a human planner. Target coverage and homogeneity slightly reduced [-0.2 %;-14.7 %] while plan complexity showed only minor changes. Increasing the sample size resulted in more reliable predictions and improved goodness-of-fit, while increasing the mean sample quality improved the outcomes but slightly reduced the models reliability. CONCLUSIONS: Repeated updates of clinical KBP models can enhance their robustness, reliability and the overall quality of automatically generated plans. The periodical expansion of the model sample accompanied by the removal of the unacceptable low quality plans should maximize the benefits of the updates while limiting the associated workload.

Saturation-scale functional evidence supports clinical variant interpretation in Lynch syndrome.

BACKGROUND: Lynch syndrome (LS) is a cancer predisposition syndrome affecting more than 1 in every 300 individuals worldwide. Clinical genetic testing for LS can be life-saving but is complicated by the heavy burden of variants of uncertain significance (VUS), especially missense changes. RESULT: To address this challenge, we leverage a multiplexed analysis of variant effect (MAVE) map covering >94% of the 17,746 possible missense variants in the key LS gene MSH2. To establish this map's utility in large-scale variant reclassification, we overlay it on clinical databases of >15,000 individuals with LS gene variants uncovered during clinical genetic testing. We validate these functional measurements in a cohort of individuals with paired tumor-normal test results and find that MAVE-based function scores agree with the clinical interpretation for every one of the MSH2 missense variants with an available classification. We use these scores to attempt reclassification for 682 unique missense VUS, among which 34 scored as deleterious by our function map, in line with previously published rates for other cancer predisposition genes. Combining functional data and other evidence, ten missense VUS are reclassified as pathogenic/likely pathogenic, and another 497 could be moved to benign/likely benign. Finally, we apply these functional scores to paired tumor-normal genetic tests and identify a subset of patients with biallelic somatic loss of function, reflecting a sporadic Lynch-like Syndrome with distinct implications for treatment and relatives' risk. CONCLUSION: This study demonstrates how high-throughput functional assays can empower scalable VUS resolution and prospectively generate strong evidence for variant classification.

Association between COVID-19 vaccination rates and the Australian 'Million Dollar Vax' competition: an observational study.

OBJECTIVE: To examine the association between financial incentives from entry into a vaccine competition with the probability of vaccination for COVID-19. DESIGN: A cross-sectional study with adjustment for covariates using logistic regression. SETTING: October and November 2021, Australia. PARTICIPANTS: 2375 respondents of the Taking the Pulse of the Nation survey. PRIMARY AND SECONDARY OUTCOME MEASURES: The proportion of respondents who had any vaccination, a first dose only, or second dose after the competition opened. RESULTS: Those who entered the competition were 2.27 (95% CI 1.73 to 2.99) times more likely to be vaccinated after the competition opened on 1 October than those who did not enter-an increase in the probability of having any dose of 0.16 (95 % CI 0.10 to 0.21) percentage points. This increase was mostly driven by those receiving second doses. Entrants were 2.39 (95% CI 1.80 to 3.17) times more likely to receive their second dose after the competition opened. CONCLUSIONS: Those who entered the Million Dollar Vax competition were more likely to have a vaccination after the competition opened compared with those who did not enter the competition, with this effect dominated by those receiving second doses.

Selective internal radiation therapy for hepatocellular carcinoma: A 15-year multicenter Australian cohort study.

BACKGROUND AND AIM: The exact place for selective internal radiation therapy (SIRT) in the therapeutic algorithm for hepatocellular carcinoma (HCC) is debated. There are limited data on its indications, efficacy, and safety in Australia. METHODS: We performed a multicenter retrospective cohort study of patients undergoing SIRT for HCC in all Sydney hospitals between 2005 and 2019. The primary outcome was overall survival. Secondary outcomes were progression-free survival and adverse events. RESULTS: During the study period, 156 patients underwent SIRT across 10 institutions (mean age 67 years, 81% male). SIRT use progressively increased from 2005 (n = 2), peaking in 2017 (n = 42) before declining (2019: n = 21). Barcelona Clinic Liver Cancer stages at treatment were A (13%), B (33%), C (52%), and D (2%). Forty-four (28%) patients had tumor thrombus. After a median follow-up of 13.9 months, there were 117 deaths. Median overall survival was 15 months (95% confidence interval 11-19). Independent predictors of mortality on multivariable analysis were extent of liver involvement, Barcelona Clinic Liver Cancer stage, baseline ascites, alpha fetoprotein, and model for end-stage liver disease score. Median progression-free survival was 6.0 months (95% confidence interval 5.1-6.9 months). Following SIRT, 11% of patients were downstaged to curative therapy. SIRT-related complications occurred in 17%: radioembolization-induced liver disease (11%), pneumonitis (3%), gastrointestinal ulceration, and cholecystitis (1% each). Baseline ascites predicted for radioembolization-induced liver disease. CONCLUSION: We present the largest Australian SIRT cohort for HCC. We have identified several factors associated with a poor outcome following SIRT. Patients with early-stage disease had the best survival with some being downstaged to curative therapy.

Lenvatinib for the treatment of hepatocellular carcinoma-a real-world multicenter Australian cohort study.

INTRODUCTION: Hepatocellular carcinoma (HCC) is a serious complication of chronic liver disease. Lenvatinib is an oral multikinase inhibitor registered to treat advanced HCC. This study evaluates the real-world experience with lenvatinib in Australia. METHODS: We conducted a retrospective cohort study of patients treated with lenvatinib for advanced HCC between July 2018 and November 2020 at 11 Australian tertiary care hospitals. Baseline demographic data, tumor characteristics, lenvatinib dosing, adverse events (AEs) and clinical outcomes were collected. Overall survival (OS) was the primary outcome. Progression free survival (PFS) and AEs were secondary outcomes. RESULTS: A total of 155 patients were included and were predominantly male (90.7%) with a median age of 65 years (interquartile range [IQR]: 59-75). The main causes of chronic liver disease were hepatitis C infection (40.0%) and alcohol-related liver disease (34.2). Median OS and PFS were 7.7 (95% confidence interval [CI]: 5.8-14.0) and 5.3 months (95% CI: 2.8-9.2) respectively. Multivariate predictors of mortality were the need for dose reduction due to AEs (Hazard ratio [HR] 0.41, p < 0.01), new or worsening hypertension (HR 0.42, p < 0.01), diarrhoea (HR 0.47, p = 0.04) and more advanced BCLC stage (HR 2.50, p = 0.04). Multivariable predictors of disease progression were higher Child-Pugh score (HR 1.25, p = 0.04), the need for a dose reduction (HR 0.45, p < 0.01) and age (HR 0.96, p < 0.001). AEs occurred in 83.9% of patients with most being mild (71.6%). CONCLUSIONS: Lenvatinib remains safe and effective in real-world use. Treatment emergent diarrhoea and hypertension, and the need for dose reduction appear to predict better OS.

Automated Dispensing Cabinet Functionality Expansion to Reduce Controlled Substance Inventory Discrepancies.

Background: Automated dispensing cabinets have the potential to create technology-induced errors that can arise during controlled substance medication dispensing. Despite enhancements made to the medication use process, the impact of ADC functionality on technology-induced controlled substance discrepancies have yet to be described. Objective: To evaluate the impact of ADC functionality expansion on technology-induced errors such as controlled substance discrepancies created during "blind inventory counts" and cassette dispensing errors. Methods: This quasi-experimental study was conducted over 18 months that evaluated the expanded use of dispensing cassettes within 8 ADCs at the University of Chicago Medicine. Unit-dose controlled substances with high usage were directed for inventory reassignment to cassettes. Controlled substance dispenses, blind inventory counts discrepancies and cassette dispensing errors were evaluated before and after cassette expansion. ADC discrepancy and Cassette Dispensing Error rates were calculated using 1-week segments across the study period. Results: Of the 64 040 dispenses during the study period, the proportion of cassette dispenses increased from 16% to 72% after cassette expansion. Controlled substance discrepancies decreased from 11 to 7 discrepancies for every 1000 dispenses (P < .0001). After cassette expansion, cassette dispensing errors increased to roughly 28 errors for every 1000 dispenses (P < .0001). Conclusion: Expansion of ADC functionality created opportunities for reduced technology-induced controlled substance discrepancy rates at the expense of increased cassette dispensing errors.

Vocational and psychosocial predictors of medical negligence claims among Australian doctors: a prospective cohort analysis of the MABEL survey.

OBJECTIVE: To understand the association between medical negligence claims and doctors' sex, age, specialty, working hours, work location, personality, social supports, family circumstances, self-rated health, self-rated life satisfaction and presence of recent injury or illness. DESIGN AND SETTING: Prospective cohort study of Australian doctors. PARTICIPANTS: 12 134 doctors who completed the Medicine in Australia: Balancing Employment and Life survey between 2013 and 2019. PRIMARY OUTCOME MEASURE: Doctors named as a defendant in a medical negligence claim in the preceding 12 months. RESULTS: 649 (5.35%) doctors reported being named in a medical negligence claim during the study period. In addition to previously identified demographic factors (sex, age and specialty), we identified the following vocational and psychosocial risk factors for claims: working full time (OR=1.48, 95% CI 1.13 to 1.94) or overtime hours (OR 1.70, 95% CI 1.29 to 2.23), working in a regional centre (OR 1.69, 95% CI 1.37 to 2.08), increasing job demands (OR 1.16, 95% CI 1.04 to 1.30), low self-rated life satisfaction (OR 1.43, 95% CI 1.08 to 1.91) and recent serious personal injury or illness (OR 1.40, 95% CI 1.13 to 1.72). Having an agreeable personality was mildly protective (OR 0.91, 95% CI 0.83 to 1.00). When stratified according to sex, we found that working in a regional area, low self-rated life satisfaction and not achieving work-life balance predicted medical negligence claims in male, but not female, doctors. However, working more than part-time hours and having a recent personal injury or illness predicted medical negligence claims in female, but not male, doctors. Increasing age predicted claims more strongly in male doctors. Personality type predicted claims in both male and female doctors. CONCLUSIONS: Modifiable risk factors contribute to an increased risk of medical negligence claims among doctors in Australia. Creating more supportive work environments and targeting interventions that improve doctors' health and well-being could reduce the risk of medical negligence claims and contribute to improved patient safety.

Motivation and competition in health care.

Non-pecuniary sources of motivation are a strong feature of the health care sector and the impact of competitive incentives on behavior may be lower where pecuniary motivation is low. This paper measures the marginal utility of income (MUY) of physicians from a stated-choice experiment, and examines whether this measure influences the association between competition faced by physicians and the prices they charge. We find that physicians are more likely to exploit a lack of competition with higher prices if they have a high MUY.

Medical negligence claims and the health and life satisfaction of Australian doctors: a prospective cohort analysis of the MABEL survey.

OBJECTIVE: To assess the association between medical negligence claims and doctors' self-rated health and life satisfaction. DESIGN: Prospective cohort study. PARTICIPANTS: Registered doctors practising in Australia who participated in waves 4 to 11 of the Medicine in Australia: Balancing Employment and Life (MABEL) longitudinal survey between 2011 and 2018. PRIMARY AND SECONDARY OUTCOME MEASURES: Self-rated health and self-rated life satisfaction. RESULTS: Of the 15 105 doctors in the study, 885 reported being named in a medical negligence claim. Fixed-effects linear regression analysis showed that both self-rated health and self-rated life satisfaction declined for all doctors over the course of the MABEL survey, with no association between wave and being sued. However, being sued was not associated with any additional declines in self-rated health (coef.=-0.02, 95% CI -0.06 to 0.02, p=0.39) or self-rated life satisfaction (coef.=-0.01, 95% CI -0.08 to 0.07, p=0.91) after controlling for a range of job factors. Instead, we found that working conditions and job satisfaction were the strongest predictors of self-rated health and self-rated life satisfaction in sued doctors. In analyses restricted to doctors who were sued, we observed no changes in self-rated health (p=0.99) or self-rated life satisfaction (p=0.59) in the years immediately following a claim. CONCLUSIONS: In contrast to prior overseas cross-sectional survey studies, we show that medical negligence claims do not adversely affect the well-being of doctors in Australia when adjusting for time trends and previously established covariates. This may be because: (1) prior studies failed to adequately address issues of causation and confounding; or (2) legal processes governing medical negligence claims in Australia cause less distress compared with those in other jurisdictions. Our findings suggest that the interaction between medical negligence claims and poor doctors' health is more complex than revealed through previous studies.
