Access intervention in an integrated, prepaid group practice: effects on primary care physician productivity.

OBJECTIVE: To estimate the joint effect of a multifaceted access intervention on primary care physician (PCP) productivity in a large, integrated prepaid group practice. DATA SOURCES: Administrative records of physician characteristics, compensation and full-time equivalent (FTE) data, linked to enrollee utilization and cost information. STUDY DESIGN: Dependent measures per quarter per FTE were office visits, work relative value units (WRVUs), WRVUs per visit, panel size, and total cost per member per quarter (PMPQ), for PCPs employed >0.25 FTE. General estimating equation regression models were included provider and enrollee characteristics. PRINCIPAL FINDINGS: Panel size and RVUs per visit rose, while visits per FTE and PMPQ cost declined significantly between baseline and full implementation. Panel size rose and visits per FTE declined from baseline through rollout and full implementation. RVUs per visit and RVUs per FTE first declined, and then increased, for a significant net increase of RVUs per visit and an insignificant rise in RVUs per FTE between baseline and full implementation. PMPQ cost rose between baseline and rollout and then declined, for a significant overall decline between baseline and full implementation. CONCLUSIONS: This organization-wide access intervention was associated with improvements in several dimensions in PCP productivity and gains in clinical efficiency.

Managed care arrangements of health networks and systems. A review of the 1999 experience.

The 1990s witnessed various health provider efforts to integrate health care delivery with financing functions. Physician and hospital-led organizations developed their own insurance products and also contracted on a capitated or shared-risk basis with health maintenance organizations (HMOs). Several studies exist on the efforts of physician-led health organizations in these areas, but few studies exist on hospital-led organizations. We examined unique data on hospital-led health networks and systems for 1999 and found that about 60% had provider-owned insurance products and 50% held capitated contracts for their affiliates. In addition, these hospital-led organizations--especially health systems--had comparable levels of capitated contracting when compared to physician-led organizations. Although interest in capitation has waned, current economic realities may reignite interest in these arrangements given their potential for containing health expenditures without increasing consumer risk. In light of this, it is now a good time for physicians and medical group managers to reflect on their experiences in the 1990s and to assess the merits and shortcomings of different intermediary organizations with which they may align.
