Cost-Effectiveness of Interprofessional Team Models: A Comparative Analysis Across Healthcare Systems

Abstract

Interprofessional team models have emerged as a promising approach to address rising healthcare costs while improving patient outcomes. However, the cost-effectiveness of various interprofessional configurations remains inadequately explored across different healthcare systems. This study examines the cost-effectiveness of interprofessional team models across diverse healthcare systems, comparing resource utilization, patient outcomes, and economic sustainability. A comparative analysis was conducted examining interprofessional team models in four healthcare systems (Beveridge, Bismarck, National Health Insurance, and Out-of-Pocket models) from 2020-2024. Data were collected from 45 healthcare organizations across 12 countries, analyzing cost per patient, readmission rates, patient satisfaction scores, and team efficiency metrics. Interprofessional teams demonstrated cost savings ranging from 12-31% compared to traditional care models, with the highest efficiency observed in primary care settings (mean cost reduction: 28%, p<0.001). The Bismarck model showed the most favorable cost-effectiveness ratio (1:2.4), while maintaining quality indicators. Reduced hospital readmissions (average 23% decrease) and shortened length of stay (1.8 days reduction) contributed significantly to cost savings. Interprofessional team models offer substantial cost-effectiveness advantages across various healthcare systems, though implementation strategies must be tailored to system-specific contexts. Initial investment in training and infrastructure is offset by long-term savings within 18-24 months.
