Association Between HEDIS Performance and Primary Care Physician Age, Group Affiliation, Training, and Participation in ACA Exchanges.

ABSTRACT:

Background

There are a limited number of studies investigating the relationship between primary care physician (PCP) characteristics and the quality of care they deliver.

Objective

To examine the association between PCP performance and physician age, solo versus group affiliation, training, and participation in California's Affordable Care Act (ACA) exchange.

Design

Observational study of 2013-2014 data from Healthcare Effectiveness Data and Information Set (HEDIS) measures and select physician characteristics.

Participants

PCPs in California HMO and PPO practices (n = 5053) with part of their patient panel covered by a large commercial health insurance company.

Main measures

Hemoglobin A1c testing; medical attention nephropathy; appropriate treatment hypertension (ACE/ARB); breast cancer screening; proportion days covered by statins; monitoring ACE/ARBs; monitoring diuretics. A composite performance measure also was constructed.

Key results

For the average 35- versus 75-year-old PCP, regression-adjusted mean composite relative performance scores were at the 60th versus 47th percentile (89% vs. 86% composite absolute HEDIS scores; p < .001). For group versus solo PCPs, scores were at the 55th versus 50th percentiles (88% vs. 87% composite absolute HEDIS scores; p < .001). The effect of age on performance was greater for group versus solo PCPs. There was no association between scores and participation in ACA exchanges.

Conclusions

The associations between population-based care performance measures and PCP age, solo versus group affiliation, training, and participation in ACA exchanges, while statistically significant in some cases, were small. Understanding how to help older PCPs excel equally well in group practice compared with younger PCPs may be a fruitful avenue of future research.

Project description:ImportanceMedicare's Bundled Payments for Care Improvement (BPCI) program, which ran from 2013 to 2018, was an important experiment in physician-focused alternative payment models. However, little is known about whether the program was associated with better quality or outcomes or lower costs.ObjectiveTo determine whether participation in BPCI among physician group practices was associated with advantageous or deleterious changes in costs or patient outcomes.Design setting and participantsThis cross-sectional study used 2013 to 2017 Medicare files and difference-in-differences (DID) models to compare the change over time in Medicare payments, patient selection, and clinical outcomes between 91 orthopedic groups in BPCI Model 2 and 169 propensity-matched controls for patients undergoing joint replacement. Analyses were performed between December 2019 and February 2021.ExposuresVoluntary participation in BPCI.Main outcomes and measuresThe primary outcome was 90-day Medicare payments; secondary outcomes were patient selection (volume, comorbidities) and clinical outcomes (30-day and 90-day emergency department visits, readmissions, mortality, and healthy days at home).ResultsThere were 74 343 patient episodes in the baseline period and 102 790 during the intervention in BPCI practices, and 88 147 patient episodes in the baseline period and 120 253 during the intervention in control practices; 291 214 of 461 598 (63.1%) patients were women, and 419 619 (90.9%) were White. At baseline, mean episode payments among BPCI-participating practices were $18 257, which decreased to $15 320 during the intervention, while control practices decreased from $17 927 to $16 170 (DID, -$1180; 95% CI, -$1565 to -$795; P < .001). Savings were driven by a decrease in postacute care spending. There were no differential changes in volume or comorbidities. The BPCI practices increased the proportion of patients discharged home compared with controls (23.6% to 43.4% vs 22.2% to 31.8%; DID, 10.2% [95% CI, 6.2% to 14.1%]). There were no differential changes in 30-day or 90-day mortality rates or emergency department visits, but 30-day and 90-day readmission rates decreased more among BPCI practices than controls (90 days: 8.7% to 7.5% vs 8.9% to 8.7%; DID, -1.0% [95% CI, -1.4% to -0.5%]), and 90-day healthy days at home increased (BPCI, 82.9 to 84.8, vs controls, 83.1 to 84.4; DID, 0.6 [95% CI, 0.4 to 0.8]).Conclusions and relevanceGroup practice participation in BPCI for joint replacement was associated with reduced Medicare payments and improvements in clinical outcomes.
