The organizational structure of medical group practices in a managed care environment

Article Abstract:

The organizational structure of medical group practices in a managed care setting was examined by surveying 155 medical clinics in the upper midwest. The study focused on three structural attributes, namely, administrative control, patient care system standardization and integration, and physician productivity. The findings indicate that internal systems to control resource use develop differently among medical groups, that the structure of the clinics is affected differently by involvement with financial risk sharing payment programs, and that the degree of financial risk-sharing for patient care seems unaffected by internal resource control and systems improvement programs.

Competitive forces in the medical group industry: a stakeholder perspective

Article Abstract:

Competition within the medical group industry is changing. The forces transforming the competitive situation include increased competition among existing medical groups, the emergence of new medical groups, the growing bargaining power of suppliers and buyers, and competition from medical group substitutes. Porter's model of competitive forces is used to examine the role played by industry stakeholders, namely, competitors, physicians, patients, managed care organizations and hospitals, and to analyze the future of medical groups.
