Article Synopsis
  • France's healthcare system faces significant challenges, including medically underserved areas and social health inequalities, which were assessed using various health indicators.
  • From 1990 to 2019, life expectancy and healthy life expectancy improved in France, ranking seventh and fourth respectively among 23 Western European countries.
  • The burden of disease, measured in disability-adjusted life-years (DALYs), decreased from 1990 to 2019, with cardiovascular diseases having a lower burden compared to other European nations, while mental and musculoskeletal disorders led in years lived with disability (YLDs).

Background: High rates of discontinuation undermine the effectiveness of adjuvant endocrine therapy (AET) among hormone-receptive breast cancer patients. Patient prognosis also relies on the successful management of cardiovascular risk, which affects a high proportion of postmenopausal women. As with AET, adherence with cardiovascular drugs is suboptimal.

Article Synopsis
  • The study evaluates the effectiveness of the Healthcare Expenditures and Conditions Mapping (HECM) algorithm in identifying various health conditions, specifically for patients with end-stage kidney disease (ESKD) in France.
  • A total of 5,971 patients were analyzed, finding that 81% were accurately identified as having ESKD in both datasets, with diabetes showing the highest accuracy.
  • The HECM performed well overall but struggled with cancer identification, suggesting further validation is needed for broader use in different patient populations.

Article Synopsis
  • The World Health Organization declared COVID-19 a pandemic on March 11, 2020, and this study aimed to assess the disease's impact in France for that year using a measure called disability-adjusted life years (DALYs).
  • The analysis utilized national data on mortality, hospital admissions, and screening, estimating a total of 990,710 DALYs lost in France in 2020, with 99% attributed to mortality and a small percentage to morbidity from symptomatic cases.
  • The findings highlighted that post-acute consequences significantly affected health outcomes, especially among younger people under 70, while the majority of life years lost occurred in individuals aged 70 and older.

  • The study analyzed survival rates after meningioma surgery from a French medical database, focusing on a large patient group over a 10-year period.
  • A total of 28,778 patients were assessed, with a high five-year relative survival rate of 96.2%, although there was a notable excess risk of mortality, particularly in males and those with certain health conditions.
  • Factors affecting survival included gender, age at surgery, tumor characteristics, previous surgeries, and treatments like radiotherapy, indicating that comprehensive patient profiles are crucial for understanding outcomes.

Novel risk-adjusted payment models for financing primary care are currently being experimented in France. In particular, pilot schemes including shared-savings contracts or prospectively allocated capitation payments are implemented for voluntary primary care structures. Such payment mechanisms require defining a risk-adjustment formula to accurately estimate expected expenditure while maintaining appropriate efficiency incentives.

Background: Survival after meningioma surgery often is reported with inadequate allowance for competing causes of death.

Methods: We processed the French Système National des Données de Santé database using an algorithm combining the type of surgical procedure and the International Classification of Diseases to retrieve appropriate cases of meningiomas. The cumulative incidence of meningioma-related death was the primary end point.

Background: Identifying patients with heart failure (HF) who are most at risk of readmission permits targeting adapted interventions. The use of administrative data enables regulators to support the implementation of such interventions.

Methods And Results: In a French nationwide cohort of patients aged 65 years or older, surviving an index hospitalization for HF in 2015 (N = 70,657), we studied HF readmission predictors available in administrative data, distinguishing HF severity from overall morbidity and taking into account the competing mortality risk, over a 1-year follow-up period.

The popularity of tattoos has increased dramatically worldwide particularly in the last three decades, giving rise to the frequent occurrence of a wide spectrum of secondary cutaneous and systemic complications. Pseudoepitheliomatous hyperplasia (PEH) is a benign irregular hyperplasia of the epidermis occurring in response to various stimuli, that clinically and histopathologically resembles cutaneous neoplasms such as squamous cell carcinoma and keratoacanthoma. In an attempt to improve the awareness of the possible occurrence of PEH in tattoos and of its diagnostic and therapeutic aspects, we present herein the case of a 30-year-old woman with histologically confirmed PEH related to a red-ink tattoo.

Background: The French National Cancer Control Plan (NCCP) launched in 2014 set the objective to improve human papillomavirus (HPV) vaccination coverage (VC). The NCCP included a measure to integrate a VC indicator in the pay for performance (P4P) scheme for general practitioners (GPs), which was not implemented. The objective of the study was to analyse the reasons for non-implementation of this measure, using the health policy analysis framework.

Objective: The objective of the study was to develop and validate two outcome-specific morbidity indices in a population-based setting: the Mortality-Related Morbidity Index (MRMI) predictive of all-cause mortality and the Expenditure-Related Morbidity Index (ERMI) predictive of health care expenditure.

Study Design And Setting: A cohort including all beneficiaries of the main French health insurance scheme aged 65 years or older on December 31, 2013 (N = 7,672,111), was randomly split into a development population for index elaboration and a validation population for predictive performance assessment. Age, gender, and selected lists of conditions identified through standard algorithms available in the French health insurance database (SNDS) were used as predictors for 2-year mortality and 2-year health care expenditure in separate models.

Pay-for-performance (P4P) has been increasingly used across different healthcare settings to incentivize the provision of targeted services. In this study, we investigated the effect of a nationwide P4P scheme for general practitioners implemented in 2012 in France, on cervical cancer screening practices. Using data from a nationally representative permanent sample of health insurance beneficiaries, we analyzed smear test use of eligible women for the years 2006-2014.

Background: Comorbidity at the time of diagnosis is an independent prognostic factor for survival among women suffering from cervical or breast cancer. Although cancer screening practices have proven their efficacy for mortality reduction, little is known about adherence to screening recommendations for women suffering from chronic conditions. We investigated the association between eleven chronic conditions and adherence to cervical and breast cancer screening recommendations in France.
