Both the number and the size of accountable care organizations (ACOs) in the Medicare Shared Savings Program have been increasing. The number of ACOs rose from 220 in 2013 to 548 in 2018, while the average number of participating clinicians in ACOs increased from 263 to 653. Although increases occurred for primary care physicians (from an average of 141 to 251) and medical specialists (from an average of 76 to 157), the increase for nonphysician practitioners (from an average of 47 to 245) was the largest. These differential increases changed the ACO workforce composition over time. The average proportion of nonphysician practitioners in ACOs grew from 18.1 percent to 38.7 percent, with a commensurate decline in the average share of primary care physicians from 60.0 percent to 42.2 percent. As value-based care models grow in prevalence, their evolving clinician composition may affect workforce patterns in the broader health care delivery system.
医疗保险共同节约计划中,负责医疗组织(ACO)的数量和规模都在不断增加。ACO的数量从2013年的220个增至2018年的548个,而ACO中参与的临床医生平均数量则从263人增加到653人。虽然初级保健医生(从平均141人增至251人)和医学专科医生(从平均76人增至157人)的数量都有所增加,但非医师从业者的数量增长幅度最大(从平均47人增至245人)。随着时间的推移,这些不同的增长改变了ACO的劳动力构成。ACO中非医师从业者的平均比例从18.1%增至38.7%,与此同时,初级保健医生的平均占比相应地从60.0%降至42.2%。随着基于价值的医疗模式日益普及,其不断变化的临床医生构成可能会影响更广泛的医疗服务提供系统中的劳动力模式。
