ABSTRACT: Objective
To assess the impact of Massachusetts Health Reform (MHR) on access, quality, and costs of outpatient care for the already-insured.Data sources/study setting
Medicare data from before (2006) and after (2009) MHR implementation.Study design
We performed a retrospective difference-in-differences analysis of quantity of outpatient visits, proportion of outpatient quality metrics met, and costs of care for Medicare patients with ? 1 chronic disease in 2006 versus 2009. We used the remaining states in New England as controls.Data collection/extraction methods
We used existing Medicare claims data provided by the Centers for Medicare and Medicaid Services.Principal findings
MHR was not associated with a decrease in outpatient visits per year compared to controls (9.4 prereform to 9.6 postreform in MA vs. 9.4-9.5 in controls, p = .32). Quality of care in MA improved more than controls for hemoglobin A1c monitoring, mammography, and influenza vaccination, and similarly to controls for diabetic eye examination, colon cancer screening, and pneumococcal vaccination. Average costs for patients in Massachusetts increased from $9,389 to $10,668, versus $8,375 to $9,114 in control states (p < .001).Conclusions
MHR was not associated with worsening in access or quality of outpatient care for the already-insured, and it had modest effects on costs. This has implications for other states expanding insurance coverage under the Affordable Care Act.

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:ObjectiveTo evaluate the impact of the 2006 Massachusetts health reform, the model for the Affordable Care Act, on short-term enrollment and utilization in the unsubsidized individual health insurance market.Data sourceSeven years of administrative and claims data from Harvard Pilgrim Health Care.Research designWe employed pre-post survival analysis and an interrupted time series design to examine changes in enrollment length, utilization patterns, and use of elective procedures (discretionary inpatient surgeries and infertility treatment) among nonelderly adult enrollees before (n = 6,912) and after (n = 29,207) the MA reform.Principal findingsThe probability of short-term enrollment dropped immediately after the reform. Rates of inpatient encounters (HR = 0.83, 95 percent CI: 0.74, 0.93), emergency department encounters (HR = 0.85, 95 percent CI: 0.80, 0.91), and discretionary inpatient surgeries (HR = 0.66 95 percent CI: 0.45, 0.97) were lower in the postreform period, whereas the rate of ambulatory visits was somewhat higher (HR = 1.04, 95 percent CI: 1.00, 1.07). The rate of infertility treatment was higher after the reform (HR = 1.61, 95 percent CI: 1.33, 1.97), driven by women in individual (vs. family) plans. The reform was not associated with increased utilization among short-term enrollees.ConclusionsMA health reform was associated with a decrease in short-term enrollment and changes in utilization patterns indicative of reduced adverse selection in the unsubsidized individual market. Adverse selection may be a problem for specific, high-cost treatments.

Project description:Racial 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.To evaluate the impact of Massachusetts health care reform on racial disparities in MIS.A 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.The 2006 Massachusetts health care reform, which expanded insurance coverage for government-subsidized, self-pay, and uninsured individuals in Massachusetts.Adjusted probability of undergoing MIS and difference-in-difference estimates.Prior 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).The 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.

Project description:BackgroundThis study examines the expansion of health insurance coverage in Massachusetts under state health reform as a natural experiment to investigate whether expanded insurance coverage reduced the likelihood of advanced stage colorectal cancer (CRC) and breast cancer (BCA) diagnosis.MethodsOur study populations include CRC or BCA patients aged 50-64 years observed in the Massachusetts Cancer Registry and Surveillance Epidemiology and End Results (SEER) registries for 2001-2013. We use difference-in-differences regression models to estimate changes in the likelihood of advanced stage diagnosis after Massachusetts health reform, relative to comparison states without expanded coverage (Connecticut, New Jersey, Georgia, Kentucky, and Michigan).ResultsWe find some suggestive evidence of a decline in the proportion of advanced stage CRC cases. Approximately half of the CRC patients in Massachusetts and control states were diagnosed at advanced stages pre reform; there was a 2 percentage-point increase in this proportion across control states and slight decline in Massachusetts post reform. Adjusted difference-in-difference estimates suggest a 3.4 percentage-point (P=0.005) or 7% decline, relative to Massachusetts baseline, in the likelihood of advanced stage diagnosis after the reform in Massachusetts, though this result is sensitive to years included in the analysis. We did not find a significant effect of reform on BCA stage at diagnosis.ConclusionsThe decline in the likelihood of advanced stage CRC diagnosis after Massachusetts health reform may suggest improvements in access to health care and CRC screening. Similar declines were not observed for BCA, perhaps due to established BCA-specific safety-net programs.

Project description:OBJECTIVE:Most inpatient care for the uninsured and other vulnerable subpopulations occurs in safety-net hospitals. As insurance expansion increases the choice of hospitals for the previously uninsured, we examined if Massachusetts health reform was associated with shifts in the volume of inpatient care from safety-net to non-safety-net hospitals overall, or among other vulnerable sociodemographic (racial/ethnic minority, low socioeconomic status, high uninsured rate area) and clinical subpopulations (emergent status, diagnosis). DATA SOURCES/STUDY SETTING:Discharge records for adults discharged from all nonfederal acute care hospitals in Massachusetts, New Jersey, New York, and Pennsylvania 2004-2010. STUDY DESIGN:Using a difference-in-differences design, we compared pre-/post-reform changes in safety-net and non-safety-net hospital discharge outcomes in Massachusetts among adults 18-64 with corresponding changes in comparisons states with no reform, overall, and by subpopulations. PRINCIPAL FINDINGS:Reform was not associated with changes in inpatient care use at safety-net and non-safety-net hospitals across all discharges or in most subpopulations examined. CONCLUSIONS:Demand for inpatient care at safety-net hospitals may not decrease following insurance expansion. Whether this is due to other access barriers or patient preference needs to be explored.

Project description:ObjectiveTo determine whether Massachusetts Health Reform improved health outcomes in uninsured patients with hyperlipidemia, diabetes, or hypertension.Data sourcePartners HealthCare Research Patient Data Registry (RPDR).Study designWe examined 1,463 patients with hyperlipidemia, diabetes, or hypertension who were uninsured in the 3 years before the 2006 Massachusetts Health Reform implementation. We assessed mean quarterly total cholesterol, glycosylated hemoglobin, and systolic blood pressure in the respective cohorts for five follow-up years compared with 3,448 propensity score-matched controls who remained insured for the full 8-year study period. We used person-level interrupted time series analysis to estimate changes in outcomes adjusting for sex, age, race, estimated household income, and comorbidity. We also analyzed the subgroups of uninsured patients with poorly controlled disease at baseline, no evidence of established primary care in the baseline period, and those who received insurance in the first follow-up year.Principal findingsIn 5 years after Massachusetts Health Reform, patients who were uninsured at baseline did not experience detectable trend changes in total cholesterol (-0.39 mg/dl per quarter, 95 percent confidence interval [-1.11 to 0.33]), glycosylated hemoglobin (-0.02 percent per quarter [-0.06 to 0.03]), or systolic blood pressure (-0.06 mmHg per quarter [-0.29 to 0.18]). Analyses of uninsured patients with poorly controlled disease, no evidence of established primary care in the baseline period, and those who received insurance in the first follow-up year yielded similar findings.ConclusionsMassachusetts Health Reform was not associated with improvements in hyperlipidemia, diabetes, or hypertension control after 5 years. Interventions beyond insurance coverage might be needed to improve the health of chronically ill uninsured persons.

Project description:ObjectiveTo estimate whether the incidence of low birthweight and rates of infant mortality were associated with Massachusetts health reform in the overall population and for subgroups that are at higher risk for poor health outcomes.Data sourcesIndividual-level data on birthweight were obtained from the National Center for Health Statistics detailed natality files, and aggregated county-level mortality rates were generated from linked birth-death files. We used restricted versions of each file that had intact state and substate geographic identifiers.Research designWe employed a quasi-experimental difference-in-differences design.Principal resultsWe found small and statistically nonsignificant associations between the reform and the incidence of low birthweight and infant mortality rates. Results were consistent across a number of subgroups and were robust to alternative comparison groups and alternative modeling assumptions.ConclusionsWe found no evidence that the Massachusetts reform was associated with improvements in individual low birthweights or county-level infant mortality rates, despite increasing health insurance coverage rates for adult women of child-bearing age. Because our mortality analysis was ecological, we are not able to draw conclusions about how an individual-level health insurance intervention for uninsured pregnant women would affect the mortality outcomes of their infants.

Project description:BackgroundMany states are implementing comprehensive programs aimed at reducing persistent barriers to contraceptive care. Evidence on the effectiveness of these programs is essential for practice improvement and policy development.ObjectiveTo evaluate changes in the probability of initiating a contraceptive method by women with employer sponsored insurance after implementation of Delaware Contraceptive Access Now (DelCAN), a statewide initiative that aimed to increase access to long-acting reversible contraceptives (LARCs).Design, setting, and participantsWe used a difference-in-differences design to examine contraceptive initiation rates. Data came from IBM Marketscan and covered women age 15-44 enrolled in employer sponsored insurance. The primary outcome was insertion of a LARC, both in the overall study population and in the immediate postpartum (IPP) setting. Secondary analysis examined changes to other contraceptive method types.ResultsThe cohort of 4,550,459 enrollees generated a sample of 11,888,837 person-years and 615,670 childbirth hospitalizations. Difference-in-differences estimates suggested that DelCAN was associated with a 0.3 percentage point (95% CI [0.2, 0.5], p<0.001) increase in the LARC insertion rate in the overall study population and a 0.4 percentage point increase (95% CI [0.2, 0.6], p<0.001) in the percent of births adopting IPP LARC. Associations between DelCAN and LARC insertion appeared stronger for adolescents compared to older women. Results for other method types were less consistent.ConclusionsA comprehensive statewide program was associated with increased LARC insertion rates among enrollees with employer sponsored insurance. Understanding the effect of these programs is critical for on-going policy development for states engaged in contraceptive access reform.

Project description:Critics of Massachusetts's health reform, a model for the Affordable Care Act, have argued that insurance expansion probably had a negative spillover effect leading to worse outcomes among already insured patients, such as vulnerable Medicare patients. Using Medicare data from 2004 to 2009, we examined trends in preventable hospitalizations for conditions such as uncontrolled hypertension and diabetes--markers of access to effective primary care--in Massachusetts compared to control states. We found that after Massachusetts's health reform, preventable hospitalization rates for Medicare patients actually decreased more in Massachusetts than in control states (a reduction of 101 admissions per 100,000 patients per quarter compared to a reduction of 83 admissions). Therefore, we found no evidence that Massachusetts's insurance expansion had a deleterious spillover effect on preventable hospitalizations among the previously insured. Our findings should offer some reassurance that it is possible to expand access to uninsured Americans without negatively affecting important clinical outcomes for those who are already insured.
