An evaluation of the 2019 reform to shift interventions from hospital to outpatients settings has shown positive effects in terms of reduced numbers of inpatient treatments.
Since early 2019, the costs of 
six groups of interventions are only reimbursed by the health insurance 
funds if they are performed on an outpatient basis (see Analyses: https://eurohealthobservatory.who.int/monitors/health-systems-monitor/analyses/hspm/switzerland-2015/outpatient-care-takes-precedence-over-inpatient-care-six-groups-of-surgical-interventions-to-be-moved-to-outpatient-care).
 Justified cases are exempt from this regulation, and in the case of 
non-covered circumstances, inpatient treatment is only possible after 
prior approval of costs by the insurer. The six groups of interventions 
are:
- Unilateral varicose vein surgery of the legs
 - Haemorrhoid procedures
 - Unilateral inguinal hernia surgery
 - Examinations/interventions on the cervix or uterus
 - Knee arthroscopy, including arthroscopic surgery on the meniscus
 - Tonsil and adenoid surgery
 
The 2019 reform has shown to be effective both in terms of volume and price.
On
 behalf of the FOPH, the Swiss Health Observatory has been monitoring in
 the first three years the actual effects of this regulation, in terms 
of number of outpatient and inpatient interventions, costs, quality of 
treatment and administrative processes
    for billing and auditing. Results show that number of inpatient 
surgeries compared to the population and the corresponding costs have 
declined more sharply since 2019 than in previous years. Depending on 
the group of procedures, this decline in volume
    varied: it ranges from 17% for knee arthroscopies to 48% for 
haemorrhoid procedures. Correspondingly, the rate of outpatient 
operations has increased in most cases.
It is not possible to analyse the effects on the quality of treatment with the routinely collected statistical data. A final evaluation will be carried out based on the results from the monitoring and the study. Based on the results of this evaluation, a decision will be made as to whether and how the “outpatient before inpatient” regulation will be expanded or adapted.
