Efficiency evaluation of urban employee's basic endowment insurance expenditure in China based on a three-stage DEA model.

With the deepening of population aging, the expenditure of basic endowment insurance in China is increasing. The urban employees' basic endowment insurance(UEBEI) system for is an important part of China's basic social endowment insurance system, which is the most important institutional guarantee for the basic needs of employees after retirement. It not only relates to the living standards of retired employees but also relates to the stability of the whole society. Especially considering the acceleration of urbanization process, the financial sustainability of the basic endowment insurance for employees is of great significance for safeguarding the pension rights of retired employees and realizing the normal operation of the whole system, and the operation efficiency of urban employees' basic endowment insurance(UEBEI) fund inevitably becomes the focus of increasing attention. Based on the panel data of 31 provinces in China from 2016 to 2020, this paper established a three-stage DEA-SFA model, and compared the differences of comprehensive technical efficiency, pure technical efficiency and scale efficiency with radar chart, aiming to explore the operating efficiency of the UEBEI in China and how environmental factors affect it. The empirical results show that at present, the overall level of the expenditure efficiency of the UEBEI fund for urban workers is not high, and all provinces have not reached the efficiency frontier level, and there is still a certain space for efficiency improvement. Fiscal autonomy and elderly dependency ratio are negatively correlated with fund expenditure efficiency, while urbanization level and marketization level are positively correlated with fund expenditure efficiency. The regional difference of fund operation efficiency is significant, from high to low, it is East China, Central China and West China. Reasonable control of environmental variables and narrowing of regional economic development and fund expenditure efficiency differences can provide some enlightenment for better realization of common prosperity.

Role of artificial intelligence in determining factors impacting patients' refractive surgery decisions.

Purpose: To create a predictive model using artificial intelligence (AI) and assess if available data from patients' registration records can help in predicting definitive endpoints such as the probability of patients signing up for refractive surgery. Methods: This was a retrospective analysis. Electronic health records data of 423 patients presenting to the refractive surgery department were incorporated into models using multivariable logistic regression, decision trees classifier, and random forest (RF). Mean area under the receiver operating characteristic curve (ROC-AUC), sensitivity (Se), specificity (Sp), classification accuracy, precision, recall, and F1-score were calculated for each model to evaluate performance. Results: The RF classifier provided the best output among the various models, and the top variables identified in this study by the RF classifier excluding income were insurance, time spent in the clinic, age, occupation, residence, source of referral, and so on. About 93% of the cases that did undergo refractive surgery were correctly predicted as having undergone refractive surgery. The AI model achieved an ROC-AUC of 0.945 with an Se of 88% and Sp of 92.5%. Conclusion: This study demonstrated the importance of stratification and identifying various factors using an AI model which could impact patients' decisions while selecting a refractive surgery. Eye centers can build specialized prediction profiles across disease categories and may allow for the identification of prospective obstacles in the patient's decision-making process, as well as strategies for dealing with them.

Effects of Urban and Rural Resident Basic Medical Insurance on Healthcare Utilization Inequality in China.

Objectives: This study aims to evaluate the effects of Urban and Rural Resident Basic Medical Insurance (URRBMI) integration on healthcare utilization and explore the contribution of URRBMI to healthcare utilization inequality among middle-aged and older adults. Methods: Using data from the China Health and Retirement Longitudinal Study (CHARLS) 2011-2018. The difference-in-difference model, concentration index (CI), and decomposition method were adopted. Results: The results suggested that the probability of outpatient visits and the number of outpatient visits had decreased by 18.2% and 10.0% respectively, and the number of inpatient visits had increased by 3.6%. However, URRBMI had an insignificant effect on the probability of inpatient visits. A pro-poor inequality for the treatment group was observed. The decomposition revealed that the URRBMI contributed to the pro-poor inequality in healthcare utilization. Conclusion: The findings suggest that URRBMI integration has decreased outpatient care utilization and improved the number of inpatient visits. While the URRBMI has improved healthcare utilization inequality, some challenges still exist. Comprehensive measures should be taken in the future.

Employment Insurance may mitigate impact of unemployment on food security: Analysis on a propensity-score matched sample from the Canadian Income Survey.

Food insecurity, the inadequate access to food due to financial constraints, affects one-sixth of Canadian households, with substantial health implications. We examine the impact of unemployment and the mitigating effect of Employment Insurance (EI) on household food insecurity in Canada. Using the Canadian Income Survey 2018-2019, we sampled 28,650 households with adult workers 18-64 years old. We used propensity score matching to pair the 4085 households with unemployed workers with 3390 households with only continuously employed workers on their propensity towards unemployment. Among unemployed households, we also matched 2195 EI recipients with 950 nonrecipients. We applied adjusted logistic regression to the two matched samples. Food insecurity affected 15.1% of the households without unemployed workers and 24.6% of their unemployed counterparts, including 22.2% of EI recipients and 27.5% of nonrecipients. Unemployment was associated with 48% (adjusted odds ratio [aOR] 1.48, 95% confidence interval [CI] 1.32-1.66; 5.67 percentage points) higher likelihood of food insecurity. This association was significant and similar across income levels, full-time and part-time workers, and household compositions. EI receipt was associated with 23% (aOR 0.77, 95% CI 0.66-0.90; 4.02 percentage points) lower likelihood of food insecurity, but this association was only significant among households with lower income, full-time workers, and children under 18. The findings suggest a broad impact of unemployment on working adults' food insecurity and a substantial mitigating effect by EI on select unemployed workers. Making EI more generous and accessible for part-time workers may help alleviate food insecurity.

One-Year Adverse Outcomes Among US Adults With Post-COVID-19 Condition vs Those Without COVID-19 in a Large Commercial Insurance Database.

Importance: Many individuals experience ongoing symptoms following the onset of COVID-19, characterized as postacute sequelae of SARS-CoV-2 or post-COVID-19 condition (PCC). Less is known about the long-term outcomes for these individuals. Objective: To quantify 1-year outcomes among individuals meeting a PCC definition compared with a control group of individuals without COVID-19. Design, Setting, and Participants: This case-control study with a propensity score-matched control group included members of commercial health plans and used national insurance claims data enhanced with laboratory results and mortality data from the Social Security Administration's Death Master File and Datavant Flatiron data. The study sample consisted of adults meeting a claims-based definition for PCC with a 2:1 matched control cohort of individuals with no evidence of COVID-19 during the time period of April 1, 2020, to July 31, 2021. Exposures: Individuals experiencing postacute sequelae of SARS-CoV-2 using a Centers for Disease Control and Prevention-based definition. Main Outcomes and Measures: Adverse outcomes, including cardiovascular and respiratory outcomes and mortality, for individuals with PCC and controls assessed over a 12-month period. Results: The study population included 13 435 individuals with PCC and 26 870 individuals with no evidence of COVID-19 (mean [SD] age, 51 [15.1] years; 58.4% female). During follow-up, the PCC cohort experienced increased health care utilization for a wide range of adverse outcomes: cardiac arrhythmias (relative risk [RR], 2.35; 95% CI, 2.26-2.45), pulmonary embolism (RR, 3.64; 95% CI, 3.23-3.92), ischemic stroke (RR, 2.17; 95% CI, 1.98-2.52), coronary artery disease (RR, 1.78; 95% CI, 1.70-1.88), heart failure (RR, 1.97; 95% CI, 1.84-2.10), chronic obstructive pulmonary disease (RR, 1.94; 95% CI, 1.88-2.00), and asthma (RR, 1.95; 95% CI, 1.86-2.03). The PCC cohort also experienced increased mortality, as 2.8% of individuals with PCC vs 1.2% of controls died, implying an excess death rate of 16.4 per 1000 individuals. Conclusions and Relevance: This case-control study leveraged a large commercial insurance database and found increased rates of adverse outcomes over a 1-year period for a PCC cohort surviving the acute phase of illness. The results indicate a need for continued monitoring for at-risk individuals, particularly in the area of cardiovascular and pulmonary management.

Pre-pandemic physical activity as a predictor of infection and mortality associated with COVID-19: Evidence from the National Health Insurance Service.

Introduction: During the coronavirus disease 2019 (COVID-19) pandemic, many populations have experienced reduced physical activity (PA) levels, weight gain, and increased anxiety and depression. However, according to a previous study, engaging in PA has a positive effect on damages caused by COVID-19. Therefore, this study aimed to investigate the association between PA and COVID-19 using the National Health Insurance Sharing Service Database in South Korea. Methods: Logistic regression analysis was used to analyze the association of PA with COVID-19 and mortality. The analysis was adjusted for body mass index, sex, age, insurance type, comorbidity, and region of residence at baseline. Disability and lifestyle (weight, smoking, and drinking status) were adjusted consecutively. Results: The results indicated that engaging in insufficient PA as per the WHO guidelines predicts a higher risk of COVID-19 when controlling for personal characteristics, comorbidity, lifestyle, disability, and mortality. Discussion: This study revealed the need to engage in PA and manage weight to reduce the risk of infection and mortality associated with COVID-19. Because engaging in PA is an important component of weight management and can help restore physical and mental health after the COVID-19 pandemic, it should be emphasized as a pillar of recovery after COVID-19.

Validation of Insurance Billing Codes for Monitoring Antenatal Screening.

BACKGROUND: Prevalence statistics for pregnancy complications identified through screening such as gestational diabetes usually assume universal screening. However, rates of screening completion in pregnancy are not available in many birth registries or hospital databases. We validated screening-test completion by comparing public insurance laboratory and radiology billing records with medical records at three hospitals in British Columbia, Canada. METHODS: We abstracted a random sample of 140 delivery medical records (2014-2019), and successfully linked 127 to valid provincial insurance billings and maternal-newborn registry data. We compared billing records for gestational diabetes screening, any ultrasound before 14 weeks gestational age, and Group B streptococcus screening during each pregnancy to the gold standard of medical records by calculating sensitivity and specificity, positive predictive value, negative predictive value, and prevalence with 95% confidence intervals (CIs). RESULTS: Gestational diabetes screening (screened vs. unscreened) in billing records had a high sensitivity (98% [95% CI = 93, 100]) and specificity (>99% [95% CI = 86, 100]). The use of specific glucose screening approaches (two-step vs. one-step) were also well characterized by billing data. Other tests showed high sensitivity (ultrasound 97% [95% CI = 92, 99]; Group B streptococcus 96% [95% CI = 89, 99]) but lower negative predictive values (ultrasound 64% [95% CI = 33, 99]; Group B streptococcus 70% [95% CI = 40, 89]). Lower negative predictive values were due to the high prevalence of these screening tests in our sample. CONCLUSIONS: Laboratory and radiology insurance billing codes accurately identified those who completed routine antenatal screening tests with relatively low false-positive rates.

Artificial Intelligence Analysis of Outdoor Sports Risk Self-Assessment on Insurance Psychology.

The development potential of China's medical insurance market is huge, and the research on medical insurance demand has always been the focus of academic discussions. As a result, the discipline of behavioral economics is derived, which aims to explain the decision-making behavior of individual insurance consumption. Among them, the focus of this study was to investigate the influence of individual psychological characteristics and cognitive level on insurance behavior under the difference of reference points. This paper combined behavioral insurance, actuarial mathematics and the econometrics knowledge system, comprehensive theoretical analysis, and empirical tests and analyzed the impact mechanism of individual frame effect on medical insurance demand under different reference points at multiple levels. At the same time, based on the risk self-assessment of outdoor sports, the artificial intelligence of insurance psychology was analyzed. Based on the correlation vector machine algorithm and the theoretical basis combined with the dual perspective of insurance products, the expected utility model was established under the "guarantee framework", and the prospect theoretical model was established under the "profit and loss framework". The framing effect was used to measure the relative size of "guarantee utility" and "profit and loss utility", and a high-insurance-rate model and a low-insurance-rate model were established. The theoretical model analysis found that under the high insurance rate, because the "profit and loss utility" is positive, the size of the individual frame effect is positively correlated with the willingness to insure. Under the low insurance rate, because the "profit and loss utility" is negative, the size of the individual frame effect is negatively correlated with the willingness to insure. The research results of this paper show that insurance is an important beginning of insurance consumption behavior, which includes the complex mentality and emotion of consumers on insurance activities. The insurance demand of policyholders is formed by the joint action of external and internal incentives. Many factors such as income level and education level play an important role in insurance consumption decision making.

Comparison of Trends in the Incidence of Traumatic Spinal Cord Injury in Daily Life, Automobile Accidents, and Industrial Accidents: A National Multi-Insurance Study in Korea.

BACKGROUND: To examine the incidence of traumatic spinal cord injury (TSCI) from all etiologies, we measured and compared the incidence of TSCI from three national or quasi-national databases in South Korea, namely, the National Health Insurance Service (NHIS), automobile insurance (AUI), and Industrial Accident Compensation Insurance (IACI). METHODS: We reviewed patients with TSCI reported in the NHIS database between 2009 and 2018, and in the AUI and IACI databases between 2014 and 2018. TSCI patients were defined as those first admitted to the hospital with a diagnosis of TSCI according to the International Classification of Diseases (10th revision) criteria. Age-adjusted incidence was calculated using direct standardization using the 2005 South Korean population or the 2000 US population as the standard population. The annual percentage changes (APC) of TSCI incidence were calculated. The Cochrane-Armitage trend test was performed according to the injured body region. RESULTS: In the NHIS database, age-adjusted TSCI incidence using the Korean standard population increased significantly from 2009 to 2018 (from 33.73 per million in 2009 to 38.14 per million in 2018, APC = 1.2%, P = 0.014). Contrarily, age-adjusted incidence in the AUI database significantly decreased from 13.88 per million in 2014 to 11.57 per million in 2018 (APC = - 5.1%, P = 0.009). In the IACI database, the age-adjusted incidence showed no significant difference, while crude incidence showed a significant increase (from 22.02 per million in 2014 to 28.92 per million in 2018, APC = 6.1%, P = 0.038). According to the age group, all the three databases showed high incidences of TSCI in those in their 60s and 70s or older. Among those in their 70s or older, the incidence of TSCI increased dramatically in the NHIS and IACI databases, while no significant trend was found in AUI database. In 2018, the number of TSCI patients was the highest among those over 70 years of age in the NHIS, whereas among those in their 50s were the highest in both AUI and IACI. The proportion of patients with cervical spinal cord injury was the most common in all these databases. CONCLUSIONS: The differences in trends in the incidence of TSCI may be due to the different etiologies and different characteristics of subjects depending on insurance type. These results imply the need for tailored medical strategies for the different injury mechanisms represented by three national insurance services in South Korea.

Comparison of Prices for Commonly Administered Drugs in Employer-Sponsored Insurance Relative to Medicare.

This cross-sectional study compares unit prices and price growth in employer-sponsored insurance and Medicare over 2016 through 2020 for physician-administered drugs with the highest use and those with the highest spending.

Patient Access to Orphan Drugs Covered by Medical Insurance in China: Real-World Evidence From Patient Survey.

BACKGROUND: After the inclusion of more high-cost orphan drugs in China's National Reimbursement Drugs List, this study investigated issues relating to patient access to the 7 medicines for 4 rare diseases after listing. METHODS: This study collected data from a national survey conducted in China. Three aspects associated with the accessibility of medicines, namely, approachability, availability, and affordability, were analyzed using descriptive statistics. In addition, multilevel logistic regression models were used to investigate the associations between patient characteristics and the accessibility of surveyed orphan drugs. RESULTS: Of the 999 completed responses included in the study, 15% of the patients (n = 150) did not use the medicines because of non-medicine-related issues. Among the 849 patients using the surveyed medications, 64.4% (n = 547) encountered the problem of unavailability, whereas 51.2% (n = 435) reported affordability as an issue, and 49.6% (n = 320) had health expenditure beyond the catastrophic threshold. The data also indicated that Commercial Medical Insurance helped patients to relieve the cost burden on orphan drugs, but the payout of Commercial Medical Insurance failed to influence patients' decisions to continue the treatments. CONCLUSION: Accessibility of orphan drugs has improved in China after their inclusion in the National Reimbursement Drugs List. Nevertheless, the availability and affordability of medicines remained the barriers for patients to access the desired treatments. It is recommended that further policy refinement in conjunction with the collaboration among healthcare stakeholders is required to deliver better care for patients with rare disease.

The Gap in Insurance Liability for Blood and Research Gamma Irradiators.

ABSTRACT: In 2019, a federal contractor accidently breached a 2,900 Ci 137 Cs sealed source while decommissioning it from a University of Washington research building, releasing a single digit curie of its contents. This event contaminated 13 people as well as all seven floors of the research building, which housed the radiation source. Estimates for clean-up costs and lost revenue exceeded $150 million. The magnitude of this cost prompted licensees in possession of such radioactive sources to question whether their insurance coverage is adequate to cover a large-scale incident and if coverage for such exposure even exists. In this article, we identify potential gaps in commercially available insurance policies by evaluating and assessing associated risks, damages, and accountability. While insurance can mitigate the expense associated with remediation, it is unlikely that sufficient limits would exist to fully protect healthcare institutions from direct financial liability in the event that their radioactive sources are implicated in a nuclear, chemical, biological, or radiological (NCBR) (sometimes called CBRN in other literature) mass contamination event. This paper seeks to outline how the risks and liability to healthcare institutions having such gamma irradiators can be reduced significantly by removing them rather than seeking to insure against the cost of remediation in the event of a leak and/or mass contamination. As such, licensees are encouraged to check their policies for the correct coverage and make sure any coverage restriction is removed from their policies. In addition, licensees are also encouraged to explore financial incentives offered by the US government programs to not only dispose of their present gamma irradiator sources at no cost but also to provide financial support to replace them with alternative technologies.

Association of State Insurance Mandates for Fertility Treatment With Multiple Embryo Transfer After Preimplantation Genetic Testing for Aneuploidy.

Importance: Multiple gestation is one of the biggest risks after in vitro fertilization (IVF), largely due to multiple embryo transfer (MET). Single embryo transfer (SET) uptake has increased over time and has been attributed to various factors, such as mandated insurance coverage for IVF and preimplantation genetic testing for aneuploidy (PGT-A). Objective: To investigate whether mandates for IVF insurance coverage are associated with decreased use of MET after PGT-A. Design, Setting, and Participants: This cohort study was conducted using data on embryo transfers reported to the Society for Assisted Reproductive Technology between 2014 and 2016. Data were analyzed from January to October 2021. Exposures: State-mandated coverage for fertility treatment and type of cycle transfer performed (PGT-A, untested fresh, and untested frozen). Main Outcomes and Measures: Use of MET compared with SET, live birth, and live birth of multiples. Results: There were 110 843 embryo transfers (mean [SD] patient age, 34.0 [4.5] years; 5520 individuals identified as African American [5.0%], 10 035 as Asian [9.0%], 5425 as Hispanic [4.9%], 45 561 as White [41.1%], and 44 302 as other or unknown race or ethnicity [40.0%]); 17 650 transfers used embryos that underwent PGT-A. Overall, among transferred embryos that had PGT-A, there were 9712 live births (55.0%). The odds of live birth were 70% higher with MET vs SET after frozen embryo transfer with PGT-A (OR, 1.70; 95% CI, 1.61-1.78), but the risk of multiples was 5 times higher (OR, 5.33; 95% CI, 5.22-5.44). The odds of MET in cycles with PGT-A in states with insurance mandates were 24% lower than in states without mandates (OR, 0.76; 95% CI, 0.68-0.85). Conclusions and Relevance: This study found that despite the promise of using SET with PGT-A, MET after PGT-A was not uncommon. This practice was more common in states without insurance mandates and was associated with a high risk of multiples.

Effect of Insurance Subsidies on Agricultural Land-Use.

This paper investigates the effect of crop insurance-subsidies on agricultural land-use allocation. Since the objective of crop insurance is to help farmers with risk management, the expected profit from crop production under crop insurance might be improved, leading farmers to allocate more land to crop production. In this paper, agricultural land-use type is classified by irrigated/unirrigated farmland and cropland/woodland/pastureland. The data come from counties from all the continental states. Considering the fractional outcome of land-use share, we apply a multinomial-fractional-logit model to estimate the effects. The results show that insurance subsidies have a significant effect on land-use allocation. An increase in insurance subsidies increases farmland-share, indicating insurance subsidies could be an efficient tool to adjust agricultural land-use allocation.

Environmental Pollution Liability Insurance Pricing and the Solvency of Insurance Companies in China: Based on the Black-Scholes Model.

Environmental pollution liability insurance is becoming increasingly important for China to achieve its emission reduction targets. Insurance pricing is a crucial factor restricting the market share of environment pollution liability insurance, from the perspective of the Black-Scholes pricing model, which in turn has influenced the solvency of insurance companies in China. Firstly, this study analyzes the problems existing in compulsory liability insurance for environmental pollution in China. It proceeds with analyzing the price of compulsory environmental pollution liability insurance using the Black-Scholes pricing model, and derives a high premium insurance rate of 2.44%. Moreover, it performs a multivariate regression analysis using the asset and liability data, taken from the annual report, to identify three key factors affecting the solvency adequacy ratio, namely, capital debt ratio, reflecting the company asset structure; net interest rate on assets, reflecting the asset scale with actual solvency; and claim ratio, reflecting the business quality. Based on the results of regression analysis and robustness test for the China Insurance Clauses (CIC) company, People's Insurance Company of China (PICC), and Asia-Pacific Property & Casualty Insurance (API) company, it is shown that the effect of total asset, total debt, capital debt ratio, claim ratio, and net interest rate on assets on the solvency adequacy ratio is significant, with respect to the size of the coefficients. Based on the Black-Scholes pricing model found in the previous cycle of liability insurance, and keeping in view the existing problems of environmental pollution liability insurance expenditure, this paper presents suggestions that are conducive to improving the solvency of insurance companies in China.

Medical insurance payment schemes and patient medical expenses: a cross-sectional study of lung cancer patients in urban China.

BACKGROUND: As the main cause of cancer death, lung cancer imposes seriously health and economic burdens on individuals, families, and the health system. In China, there is no national study analyzing the hospitalization expenditures of different payment methods by lung cancer inpatients. Based on the 2010-2016 database of insured urban resident lung cancer inpatients from the China Medical Insurance Research Association (CHIRA), this paper aims to investigate the characteristics and cost of hospitalized lung cancer patient, to examine the differences in hospital expenses and patient out-of-pocket (OOP) expenses under four medical insurance payment methods: fee-for-service (FFS), per-diem payments, capitation payments (CAP) and case-based payments, and to explore the medical insurance payment method that can be conducive to controlling the cost of lung cancer. METHOD: This is a 2010-2016, 7-year cross-sectional study. CHIRA data are not available to researchers after 2016. The Medical Insurance Database of CHIRA was screened using the international disease classification system to yield 28,200 inpatients diagnosed with lung cancer (ICD-10: C34, C34.0, C34.1, C34.2, C34.3, C34.8, C34.9). The study includes descriptive analysis and regression analysis based on generalized linear models (GLM). RESULTS: The average patient age was 63.4 years and the average length of hospital stay (ALOS) was 14.2 day; 60.7% of patients were from tertiary hospitals; and 45% were insured by FFS. The per-diem payment had the lowest hospital expenses (RMB7496.00/US$1176.87), while CAP had the lowest OOP expenses (RMB1328.18/US$208.52). Compared with FFS hospital expenses, per-diem was 21.3% lower (95% CI = -0.265, -0.215) and case-based payment was 8.4% lower (95% CI = -0.151, -0.024). Compared with the FFS, OOP expenses, per-diem payments were 9.2% lower (95% CI = -0.130, -0.063) and CAP was 15.1% lower (95% CI = -0.151, -0.024). CONCLUSION: For lung cancer patients, per-diem payment generated the lowest hospital expenses, while CAP meant patients bore the lowest OOP costs. Policy makers are suggested to give priority to case-based payments to achieve a tripartite balance among medical insurers, hospitals, and insured members. We also recommend future studies comparing the disparities of various diseases for the cause of different medical insurance schemes.

Cricket injury in New Zealand: a study of injury insurance claims from 2008 to 2018.

OBJECTIVES: This study aimed to quantify injury claims in organised community cricket in New Zealand over a 10-year period, 1 July, 2008 to June 30, 2018. DESIGN: Retrospective analysis of administrative insurance claims data from the Accident Compensation Corporation (ACC), New Zealand. METHODS: Injury claims relating to cricket in males and females in New Zealand were identified from coded data and relevant text searches of routinely collected claims data. Summary statistics for key variables (age, body part, injury type, and injury factors) are presented together with annual injury claim incidence rates (ICR) calculated using population-based denominators. RESULTS: There were 62,776 claims for cricket injury occurring at a place of recreation/sports. Most claims were in males (91.4%) and those aged 15-19 year old age group. There was an increase in the total number of injury claims over the 10-year period (1.5%, p = 0.04), but the ICR was consistent (males: varying between 258.8-304.8, and females: 22.6-28.3 claims annually per 100,000 population). Soft tissue injury claims were the most common injury type. Lumbosacral claims were most common for bowlers (78%). Lower limb injury claims were the predominant claim from batting (36%) and fielding (42%), with knee injury claims (34%) being the most common lower-limb injury location. CONCLUSIONS: Lumbosacral, shoulder and knee injuries were common amongst all playing positions and worthy of preventative attention. Strategies targeting prevention of these injuries may reduce the ICR within the ACC.

Comparison of Cardiovascular Procedure Rates in Patients With Supplementary vs Basic Insurance in Switzerland.

Importance: Switzerland's mandatory health insurance provides universal coverage, but residents can opt for supplementary private insurance for nonessential, nonvital amenities. It is debated whether people with supplementary private insurance receive overtreatment due to financial incentives. Objective: To assess whether incidence rates of cardiovascular procedures in people with supplementary private insurance are higher than in those with basic insurance only. Design, Setting, and Participants: A population-based weighted cohort comparative effectiveness study, using administrative claims data from Switzerland assessing incidence rates (IRs), was conducted in adults undergoing a nonemergency cardiovascular inpatient procedure from January 1, 2012, to December 31, 2020. Analysis included primary or secondary discharge procedure codes for 1 of the following: percutaneous transluminal coronary angioplasty (PTCA), left atrial appendage (LAA) occlusion, patent foramen ovale (PFO) closure, transcatheter aortic valve replacement (TAVR), mitral valve clip implantation, cardiac pacemaker implantation, and atrial fibrillation/atrial flutter ablation. Exposures: Supplementary private health insurance. Main Outcomes and Measures: Incidence rates of cardiovascular procedures between insurance groups calculated by negative binomial regression adjusted by inverse probability weights. Results: Of 590 919 admissions (median age, 68 years; IQR, 57-77 years), 55.5% male, 15.7% non-Swiss nationality), 70.1% had basic insurance only. Independent of insurance status, IR for all cardiovascular procedures steadily increased over the study years. In general, people with supplementary private insurance received cardiovascular procedures more frequently (IR ratio [IRR], 1.11; 99% CI, 1.10-1.11) than people with basic insurance only. There was also an increase for every procedure: PTCA (IRR, 1.12; 99% CI, 1.12-1.13), LAA closure (IRR, 1.15; 99% CI, 1.13-1.16), mitral valve clip implantation (IRR, 1.08; 99% CI, 1.07-1.09), TAVR (IRR, 1.04; 99% CI, 1.03-1.06), PFO closure (IRR, 1.01; 99% CI, 1.00-1.02), pacemaker implantation (IRR, 1.08; 99% CI, 1.07-1.09), and atrial fibrillation/atrial flutter ablation (IRR, 1.12; 99% CI, 1.11-1.12). Sensitivity analyses, including side procedures, stratification by length of stay, and propensity score matching, suggested robustness of the results. Conclusions and Relevance: This study found an association between supplementary private insurance and a higher likelihood of receiving nonemergency cardiovascular procedures. Whether this higher rate of procedures in people with supplementary private insurance is based on clinical reasoning or due to financial incentives warrants further exploration.
