General-practitioner-centered health care: current results from the implementation of the German model

TL;DR

This study shows that a general practitioner-led healthcare model in Germany improves healthcare outcomes and reduces unnecessary hospitalizations and specialist visits.

Contribution

The study provides empirical evidence of the effectiveness of the German GPCHC model in improving primary care outcomes.

Findings

Patients in the GPCHC program had fewer uncoordinated specialist consultations and hospitalizations.

The model showed reduced use of me-too drugs compared to regular primary care.

Outcomes aligned with strong primary care systems in the Netherlands, UK, and Nordic countries.

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.
