Abstract
Primary care-centered healthcare models, particularly those led by general practitioners (GPs), are increasingly adopted to address global healthcare challenges including rising costs, fragmented services, and chronic disease burdens. In Germany, the “Hausarztzentrierte Versorgung” (English: General Practitioner-Centered Health Care, GPCHC) program aims to reinforce the role of GPs as care coordinators. Within this study we evaluated data from the implemented German GPCHC model in Baden-Württemberg, a German federal State with about 11 Mio inhabitants and compared outcomes with international benchmarks for strong primary care. The analysis is based on administrative health insurance data of almost two million individuals. We compared patients enrolled in GPCHC with patients receiving regular primary care in 2022 in terms of key indicators of healthcare utilization (GP contacts, uncoordinated consultations with a non-GP-specialist, all-cause hospitalizations, potentially avoidable hospitalizations (PAHs), and prescription of me-too drugs. For patients enrolled in the GPCHC program, consistently favorable outcomes were observed with respect to these key indicators. These findings align with international evidence from strong primary care systems in the Netherlands, the United Kingdom, and Nordic countries. The proposed model presents a scalable framework for strengthening primary care delivery in complex healthcare systems.
