Secondary data
SECONDARY
After submitting the certificate and vaccinating at least 20 patients aged 60 and older insured by a substitute health insurance fund in the first quarter of evaluation, the GP will receive an initial starter lump sum payment. Through this lump sum payment, the GP is marked as a participant in the billing data of the ASHIP and is available in a pseudonymised form for the summative evaluation over all quarters considered. Since secondary data (extract of pseudonymised contractual GP billing data according to § 295 SGB V) is used, the relevant data is available for both the intervention and the control group.
