Disparities in health care use among low-salary and high-salary employees.

OBJECTIVES: To examine how health care utilization and spending vary for low-income employees compared with high-income employees enrolled in an employer-sponsored high-deductible health plan (HDHP). STUDY DESIGN: We use commercial medical claims data and administrative human resource data from a large employer between 2014 and 2018. We link the administrative data, which include details on salary and other benefit choices, to each employee in each year with medical claims. Our variables of interest include medical spending and utilization outcomes grouped into different care settings. METHODS: Using multivariate regressions, we estimate the association between salary buckets and health care utilization and spending, controlling for demographic characteristics, comorbidities of employees, human resource health plan benefits, and geography. RESULTS: Employees earning less than $75,000 show lower rates of utilization and spending on preventive measures, such as outpatient visits and prescription drugs, while having higher rates of utilization of preventable and avoidable emergency department visits and inpatient stays, resulting in lower overall health care spending among lower-salary employees. CONCLUSIONS: Low-salary employees enrolled in HDHPs have higher rates of acute care utilization and spending but lower rates of primary care spending compared with high-salary employees. Results suggest that HDHPs discourage routine physician-patient care among low-salary employees.

Evaluation of value-based insurance design for primary care.

OBJECTIVES: To evaluate the impact of value-based insurance design (VBID), which removed patient cost sharing for primary care visits, on healthcare spending in a large, geographically diverse employer. STUDY DESIGN: Quasi-experimental, difference-in-differences (DID) design, administrative claims-based study. METHODS: Healthcare spending during the preintervention period (2008 and 2009) was compared with the postintervention period (2011 through 2014) to measure the impact of removing primary care cost sharing. The study population included Anthem commercially insured enrollees with continuous medical eligibility from 2008 to 2014 who were younger than 65 years. The VBID cohort included health plan enrollees from a national large employer that implemented the benefit change. The comparison cohort included other Anthem enrollees who did not have a similar benefit change and were propensity score-matched to the VBID cohort. Utilization of various types of healthcare services was also examined. RESULTS: The VBID cohort experienced a $12.0 per member per month relative reduction in overall spending compared with the comparison cohort (P = .02). The trend was driven by reductions in expenditures for emergency department (ED) visits ($1.3 relative reduction; DID, -10.0%; P = .03) and other outpatient services ($7.6 relative reduction; DID, -5.8%; P = .02), which aligned with reduced utilization of ED visits (DID, -4.5%; P = .07) and other outpatient services (DID, -4.1%; P = .004). For physician office visits, the VBID cohort did not experience a significant relative increase compared with the comparison cohort (DID, 0.9%; P = .25). CONCLUSIONS: The attempt to increase primary care access by reducing cost sharing did not produce a negative outcome in terms of total spending for healthcare.

Strategies to reduce nonurgent emergency department use: experience of a Northern Virginia Employer Group.

BACKGROUND: This administrative claims analysis evaluated the impact of a health plan-sponsored Emergency Room Utilization Management Initiative (ERUMI), which combined increased patient copays for ED visits with educational outreach to reduce inappropriate ED use and encourage use of retail health clinics (RHCs) and other alternative treatment sites among a commercially insured population. METHODS: Emergency department (ED) utilization rates for select acute but nonurgent conditions that could be treated appropriately in an RHC were compared for members of an employer group with (intervention group) and without (comparators) ERUMI. Utilization was compared for baseline period (January-June 2009) and ERUMI implementation period (January-June 2010). RESULTS: A total of 56,896 members (14,224 intervention, 42,672 matched comparators) were included. ED utilization for conditions that could be treated appropriately by RHCs decreased by 10.39 visits/1000 members in the intervention group versus 6.29 visits in comparators. RHC visits rose for both the groups, with a greater increase in the intervention group (22.61 visits/1000 members, P<0.001) versus comparison (1.64/1000, P=0.064). After ERUMI implementation, intervention group members were nearly 5 times more likely than comparators to choose RHCs over ED for nonurgent care. CONCLUSIONS: The health plan-sponsored ERUMI program, consisting of both financial and educational components, decreased nonurgent ED utilization while increasing the use of alternative treatment sites.
