Survival Rates in Trauma Patients Following Health Care Reform in Massachusetts.

ABSTRACT:

Importance

Massachusetts introduced health care reform (HCR) in 2006, expecting to expand health insurance coverage and improve outcomes. Because traumatic injury is a common acute condition with important health, disability, and economic consequences, examination of the effect of HCR on patients hospitalized following injury may help inform the national HCR debate.

Objective

To examine the effect of Massachusetts HCR on survival rates of injured patients.

Design, setting, and participants

Retrospective cohort study of 1,520,599 patients hospitalized following traumatic injury in Massachusetts or New York during the 10 years (2002-2011) surrounding Massachusetts HCR using data from the State Inpatient Databases. We assessed the effect of HCR on mortality rates using a difference-in-differences approach to control for temporal trends in mortality.

Intervention

Health care reform in Massachusetts in 2006.

Main outcome and measure

Survival until hospital discharge.

Results

During the 10-year study period, the rates of uninsured trauma patients in Massachusetts decreased steadily from 14.9% in 2002 to 5.0.% in 2011. In New York, the rates of uninsured trauma patients fell from 14.9% in 2002 to 10.5% in 2011. The risk-adjusted difference-in-difference assessment revealed a transient increase of 604 excess deaths (95% CI, 419-790) in Massachusetts in the 3 years following implementation of HCR.

Conclusions and relevance

Health care reform did not affect health insurance coverage for patients hospitalized following injury but was associated with a transient increase in adjusted mortality rates. Reducing mortality rates for acutely injured patients may require more comprehensive interventions than simply promoting health insurance coverage through legislation.

Project description:Massachusetts' health care reform substantially decreased the percentage of uninsured residents. However, less is known about how reform affected access to care, especially according to insurance type.To assess access to care in Massachusetts after implementation of health care reform, based on insurance status and type.We surveyed a convenience sample of 431 patients presenting to the Emergency Department of Massachusetts' second largest safety net hospital between July 25, 2009 and March 20, 2010.Demographic and clinical characteristics, insurance coverage, measures of access to care and cost-related barriers to care.Patients with Commonwealth Care and Medicaid, the two forms of insurance most often newly-acquired under the reform, reported similar or higher utilization of and access to outpatient visits and rates of having a usual source of care, compared with the privately insured. Compared with the privately insured, a significantly higher proportion of patients with Medicaid or Commonwealth Care Type 1 (minimal cost sharing) reported delaying or not getting dental care (42.2 % vs. 27.1 %) or medication (30.0 % vs. 7.0 %) due to cost; those with Medicaid also experienced cost-related barriers to seeing a specialist (14.6 % vs. 3.5 %) or getting recommended tests (15.6 % vs. 5.9 %). Those with Commonwealth Care Types 2 and 3 (greater cost sharing) reported significantly more cost-related barriers to obtaining care than the privately insured (45.0 % vs. 16.0 %), to seeing a primary care doctor (25.0 % vs. 6.0 %) or dental provider (58.3 % vs. 27.1 %), and to obtaining medication (20.8 % vs. 7.0 %). No differences in cost-related barriers to preventive care were found between the privately and publicly insured.Access to care improved less than access to insurance following Massachusetts' health care reform. Many newly insured residents obtained Medicaid or state subsidized private insurance; cost-related barriers to access were worse for these patients than for the privately insured.

Project description:ImportanceRacial disparities in receipt of minimally invasive surgery (MIS) persist in the United States and have been shown to also be associated with a number of driving factors, including insurance status. However, little is known as to how expanding insurance coverage across a population influences disparities in surgical care.ObjectiveTo evaluate the impact of Massachusetts health care reform on racial disparities in MIS.Design, setting, and participantsA retrospective cohort study assessed the probability of undergoing MIS vs an open operation for nonwhite patients in Massachusetts compared with 6 control states. All discharges (n = 167,560) of nonelderly white, black, or Latino patients with government insurance (Medicaid or Commonwealth Care insurance) or no insurance who underwent a procedure for acute appendicitis or acute cholecystitis at inpatient hospitals between January 1, 2001, and December 31, 2009, were assessed. Data are from the Hospital Cost and Utilization Project State Inpatient Databases.InterventionThe 2006 Massachusetts health care reform, which expanded insurance coverage for government-subsidized, self-pay, and uninsured individuals in Massachusetts.Main outcomes and measuresAdjusted probability of undergoing MIS and difference-in-difference estimates.ResultsPrior to the 2006 reform, Massachusetts nonwhite patients had a 5.21-percentage point lower probability of MIS relative to white patients (P < .001). Nonwhite patients in control states had a 1.39-percentage point lower probability of MIS (P = .007). After reform, nonwhite patients in Massachusetts had a 3.71-percentage point increase in the probability of MIS relative to concurrent trends in control states (P = .01). After 2006, measured racial disparities in MIS resolved in Massachusetts, with nonwhite patients having equal probability of MIS relative to white patients (0.06 percentage point greater; P = .96). However, nonwhite patients in control states without health care reform have a persistently lower probability of MIS relative to white patients (3.19 percentage points lower; P < .001).Conclusions and relevanceThe 2006 Massachusetts insurance expansion was associated with an increased probability of nonwhite patients undergoing MIS and resolution of measured racial disparities in MIS.

Project description:The 2006 Massachusetts health reform substantially decreased uninsurance rates. Yet, little is known about the reform's impact on actual health care utilization among poor and minority populations, particularly for receipt of inpatient surgical procedures that are commonly initiated by outpatient physician referral.Using discharge data on Massachusetts hospitalizations for 21 months before and after health reform implementation (7/1/2006-12/31/2007), we identified all nonobstetrical major therapeutic procedures for patients aged 40 or older and for which ?70% of hospitalizations were initiated by outpatient physician referral. Stratifying by race/ethnicity and patient residential zip code median (area) income, we estimated prereform and postreform procedure rates, and their changes, for those aged 40-64 (nonelderly), adjusting for secular changes unrelated to reform by comparing to corresponding procedure rate changes for those aged 70 years and above (elderly), whose coverage (Medicare) was not affected by reform.Overall increases in procedure rates (among 17 procedures identified) between prereform and postreform periods were higher for nonelderly low area income (8%, P=0.04) and medium area income (8%, P<0.001) cohorts than for the high area income cohort (4%); and for Hispanics and blacks (23% and 21%, respectively; P<0.001) than for whites (7%). Adjusting for secular changes unrelated to reform, postreform increases in procedure utilization among nonelderly were: by area income, low=13% (95% confidence interval (CI)=[9%, 17%]), medium=15% (95% CI [6%, 24%]), and high=2% (95% CI [-3%, 8%]); and by race/ethnicity, Hispanics=22% (95% CI [5%, 38%]), blacks=5% (95% CI [-20%, 30%]), and whites=7% (95% CI [5%, 10%]).Postreform use of major inpatient procedures increased more among nonelderly lower and medium area income populations, Hispanics, and whites, suggesting potential improvements in access to outpatient care for these vulnerable subpopulations.
