Retrospective empirical analysis of the success rate of inguinal hernia operations in outpatient and inpatient sectors: a cohort study

A sector-specific allocation based on the analysed parameters cannot be justified based on evidence. Since inpatient procedures do not show consistent superiority, there is no medical advantage over outpatient procedures. A cost-adjusted design of hybrid DRGs appears necessary to enable indication-appropriate procedure selection and to avoid potential misguided incentives that compromise the quality of care.
