Purpose: To determine the practice variation in the rate of Nd:YAG laser capsulotomy within 1 year after cataract surgery and to identify possible associations with physician practice styles.
Setting: All hospitals and private clinics in the Netherlands.
Design: Retrospective observational study.
Study Design: Retrospective cohort study.
Objective: There is only limited data on the outcome of primary surgery of lumbar disk herniation (LDH) in Dutch patients. The objective of this study is to describe undesirable outcomes after primary LDH.
Background: Quality indicators are used to benchmark and subsequently improve quality of healthcare. However, defining good quality indicators and applying them to high-volume care such as skin cancer is not always feasible.
Objectives: To determine whether claims data could be used to benchmark high-volume skin cancer care and to assess clinical practice variation.
Since intensive care unit (ICU) admission and chemotherapy use near death impair the quality of life, we studied the prevalence of both and their correlation with hospital volume in incurable gastroesophageal cancer patients as both impair the quality of life. We analyzed all Dutch patients with incurable gastroesophageal cancer who died in 2017-2018. National insurance claims data were used to determine the prevalence of ICU admission and chemotherapy use (stratified on previous chemotherapy treatment) at three and one month(s) before death.

Design: Descriptive, retrospective research based on claims data of Dutch health insurers.

Objective: Several studies have shown that patients admitted with an acute myocardial infarction during the weekends have a higher mortality rate than those admitted during weekdays, possibly attributable to less trained personnel available and a lower use of medical procedures. The current study aimed to assess this ‘weekend-effect’ in a nationwide registry.
Methods: In the Netherlands, all inhabitants are, by law, obliged to have health insurance and all claim data are centrally registered.
Objective: In the era of limited healthcare budgets, healthcare costs of heart valve implantations need to be considered to inform cost-effectiveness analyses. We aimed to provide age group-specific costs estimates of heart valve implantations, related complications and other healthcare utilisation following the intervention.
Methods: We performed retrospective analyses of healthcare costs of patients who had undergone heart valve implantations in 2010-2013 and controls using claims data from Dutch health insurers.
