Background: Evidence-based interventions to reduce hospital readmissions may not generalize to resource-constrained safety-net hospitals., Objective: To determine if an intervention by patient navigators (PNs), hospital-based Community Health Workers, reduces readmissions among high risk, low socioeconomic status patients., Design: Randomized controlled trial., Participants: General medicine inpatients having at least one of the following readmission risk factors: (1) age ≥60 years, (2) any in-network inpatient admission within the past 6 months, (3) length of stay ≥3 days, (4) admission diagnosis of heart failure, or (5) chronic obstructive pulmonary disease. The analytic sample included 585 intervention patients and 925 controls., Interventions: PNs provided coaching and assistance in navigating the transition from hospital to home through hospital visits and weekly telephone outreach, supporting patients for 30 days post-discharge with discharge preparation, medication management, scheduling of follow-up appointments, communication with primary care, and symptom management., Main Measures: The primary outcome was in-network 30-day hospital readmissions. Secondary outcomes included rates of outpatient follow-up. We evaluated outcomes for the entire cohort and stratified by patient age >60 years (425 intervention/584 controls) and ≤60 years (160 intervention/341 controls)., Key Results: Overall, 30-day readmission rates did not differ between intervention and control patients. However, the two age groups demonstrated marked differences. Intervention patients >60 years showed a statistically significant adjusted absolute 4.1% decrease [95% CI: -8.0%, -0.2%] in readmission with an increase in 30-day outpatient follow-up. Intervention patients ≤60 years showed a statistically significant adjusted absolute 11.8% increase [95% CI: 4.4%, 19.0%] in readmission with no change in 30-day outpatient follow-up., Conclusions: A patient navigator intervention among high risk, safety-net patients decreased readmission among older patients while increasing readmissions among younger patients. Care transition strategies should be evaluated among diverse populations, and younger high risk patients may require novel strategies.

Health insurance exchanges created under the Affordable Care Act will offer coverage to people who lack employer-sponsored insurance or have incomes too high to qualify for Medicaid. However, plans offered through an exchange may include high levels of cost sharing. We surveyed families participating in unsubsidized plans offered in the Massachusetts Commonwealth Health Insurance Connector Authority, an exchange created prior to the 2010 national health reform law, and found high levels of financial burden and higher-than-expected costs among some enrollees. The financial burden and unexpected costs were even more pronounced for families with greater numbers of children and for families with incomes below 400 percent of the federal poverty level. We conclude that those with lower incomes, increased health care needs, and more children will be at particular risk after they obtain coverage through exchanges in 2014. Policy makers should develop strategies to further mitigate the financial burden for enrollees who are most susceptible to encountering higher-than-expected out-of-pocket costs, such as providing cost calculators or price transparency tools.

In 2022 twenty-five million people are expected to purchase health insurance through exchanges to be established under the Affordable Care Act. Understanding how people seek information and make decisions about the insurance plans that are available to them may improve their ability to select a plan and their satisfaction with it. We conducted a survey in 2010 of enrollees in one plan offered through Massachusetts's unsubsidized health insurance exchange to analyze how a sample of consumers selected their plans. More than 40 percent found plan information difficult to understand. Approximately one-third of respondents had help selecting plans-most commonly from friends or family members. However, one-fifth of respondents wished they had had help narrowing plan choices; these enrollees were more likely to report negative experiences related to plan understanding, satisfaction with affordability and coverage, and unexpected costs. Some may have been eligible for subsidized plans. Exchanges may need to provide more resources and decision-support tools to improve consumers' experiences in selecting a health plan.

Objective: To examine whether high-deductible health plans (HDHPs) that exempt prescription drugs from full cost sharing preserve medication use for major chronic illness, compared with traditional HMOs with similar drug cost sharing., Data Sources/study Setting: We examined 2001-2008 pharmacy claims data of 3,348 continuously enrolled adults in a Massachusetts health plan for 9 months before and 24 months after an employer-mandated switch from a traditional HMO plan to a HDHP, compared with 20,534 contemporaneous matched HMO members. Both study groups faced similar three-tiered drug copayments. We calculated daily medication availability for all prescription drugs and four chronic medication classes: hypoglycemics, lipid-lowering agents, antihypertensives, and chronic obstructive pulmonary disease (COPD)/asthma controllers., Study Design: Interrupted time-series with comparison group study design examining monthly level and trend changes in prescription drug utilization., Principal Findings: The HDHP and control groups had comparable changes in the level and trend of all drugs after the index date; we detected similar patterns in the use of lipid-lowering agents, antihypertensives, and COPD/asthma controllers. Some evidence suggested a small relative decline in hypoglycemic use among diabetic patients in HDHPs., Conclusions: Switching to an HDHP that included modest drug copayments did not change medication availability or reduce use of essential medications for three common chronic illnesses., (© Health Research and Educational Trust.)

Background: The 2010 Patient Protection and Affordable Care Act (PPACA) has been controversial. The potential impact of national healthcare reform may be considered using a similar set of state-level reforms including exchanges and a mandate, enacted in 2006 in Massachusetts., Purpose: To evaluate the effects of reforms on healthcare access, affordability, and disparities., Design: Interrupted time series with comparison series., Setting/participants: Longitudinal survey data from 2002 to 2009 from the Behavioral Risk Factor Surveillance System including 178,040 nonelderly adults residing in Massachusetts, Vermont, New Hampshire, Rhode Island, and Connecticut. Analysis was conducted from January to August 2010., Intervention: Massachusetts 2006 healthcare reform, which included an individual health insurance mandate., Main Outcome Measures: Being uninsured, having no personal doctor, and forgoing care because of cost, evaluated in Massachusetts and four comparison states before (2002-2005) and after (2007-2009) the healthcare reform. Effects on disparities defined by race, education, income, and employment also were assessed., Results: Living in Massachusetts in 2009 was associated with a 7.6 percentage point (95% CI=3.9, 11.3) higher probability of being insured; 4.8 percentage point (-0.9, 10.6) lower probability of forgoing care because of cost; and a 6.6 percentage point (1.9, 11.3) higher probability of having a personal doctor, compared to expected levels in the absence of reform, defined by trends in control states and adjusting for socioeconomic factors. The effects of the reform on insurance coverage attenuated from 2008 to 2009. In a socioeconomically disadvantaged group, the reforms had a greater effect in improving outcomes on the absolute but not relative scale., Conclusions: Healthcare reforms in Massachusetts, which included a health insurance mandate, were associated with significant increases in insurance coverage and access. The absolute effects of the reform were greater for disadvantaged populations. This is important evidence to consider as debate over national healthcare reform continues., (Copyright © 2011 American Journal of Preventive Medicine. Published by Elsevier Inc.

Objective: To evaluate the impact of switching from an HMO to a high-deductible health plan on the costs and utilization of maternity care., Study Design: Pre–post design, with a control group., Methods: We compared 229 women who delivered babies before or after their employers mandated a switch from HMO coverage to a high-deductible health plan, with a control group of 2180 matched women who delivered babies while their employers remained in an HMO plan. Administrative claims from a large Massachusetts-based health insurance program were used in a difference-in-differences regression analysis., Results: Mean out-of-pocket maternity care costs for high-deductible group members increased from $356 for women who delivered before the insurance transition (n = 86) to $942 for women who delivered after the transition (n = 143), compared with a change from $262 (n = 711) to $282 (n = 1569) for HMO members, a relative increase of 106% (P <.001) for high-deductible members. Delivery after transition to a high-deductible plan was not associated with changes in the odds of receiving early prenatal care (odds ratio [OR], 1.02; 95% confidence interval [CI], 0.32-3.19), recommended prenatal visits (OR, 1.64; 95% CI, 0.89-3.02), or postpartum care (OR, 0.74; 95% CI, 0.42-1.32)., Conclusions: Switching from an HMO to a high-deductible plan with exemptions for routine care increased out-of-pocket member costs for maternity care, but had no apparent adverse impacts on receipt of recommended prenatal and postpartum care.

Objective: To examine how enrollment in high-deductible health plans (HDHPs) affects use of well-child visits relative to traditional plans, when preventive care is exempt from the deductible., Study Design: Pre-post comparison between groups., Methods: We selected children aged <18 years enrolled in a large Massachusetts health plan through employers offering only 1 type of plan. Children were in traditional plans for a 12-month baseline period between 2001 and 2004, then were either switched by a decision of the parent's employer to an HDHP or kept in the traditional plan (controls) for a 12-month follow-up period. Preventive and other office visits were exempt from the deductible and subject to copayments, as in traditional plans. The primary outcome was whether the child received well-child visits recommended for the 12-month period. Using generalized linear mixed models, we compared the change in receipt of recommended well-child visits between baseline and follow-up for the HDHP group relative to controls., Results: We identified 1598 children who were switched to HDHPs and 10,093 controls. Between baseline and follow-up, the mean proportion of recommended well-child visits received by HDHP children decreased slightly from 0.846 to 0.841, and from 0.861 to 0.855 for controls. In adjusted models, there was no significant difference in the change in probability that recommended well-child visits were received by HDHP children compared with controls (P = .69)., Conclusions: Receipt of recommended well-child visits did not change for children switching from traditional plans to HDHPs that exempt preventive care from the deductible.

Objective: There is concern that high-deductible health plans may have negative effects on vulnerable groups. The objective of this study was to compare the characteristics of families who have children and switch to high-deductible health plans with those who stay in traditional plans., Methods: This double-cohort study included families who had children aged <18 years and were enrolled in a Massachusetts health plan through employers who did not offer a choice of health plans. We identified families who had traditional health maintenance organization plans for a 12-month baseline period between 2001 and 2004 and compared families whose coverage was then switched to a high-deductible health plan by their employers with similar families whose employer chose to remain in the traditional plan (controls). Data came from health plan enrollment and claims datasets and census data. We used multivariate logistic regression models to compare the characteristics of families who were switched to high-deductible health plans with controls., Results: We identified 839 families who had children and whose employer switched them to high-deductible health plans and 5133 controls. Among families with large employers, the adjusted odds of the employer switching to a high-deductible health plan were higher for families living in high-poverty neighborhoods. Among families with small employers, the adjusted odds of the employer switching to a high-deductible health plan were lower for families with more children, above-average family morbidity, and baseline total expenditures >$7000., Conclusions: Among families with large employers offering a single health plan, those from low-income neighborhoods are more likely to be switched to high-deductible health plans. In contrast, families with small employers offering a single plan are more likely to be switched to high-deductible health plans if they are healthier and have lower baseline costs. These findings suggest that families with children in high-deductible plans may represent two distinct groups, one with higher-risk characteristics and another with lower-risk characteristics compared with those in traditional plans.

Objectives: Reducing unnecessary antibiotic use, particularly among children, continues to be a public health priority. Previous intervention studies have been limited by size or design and have shown mixed results. The objective of this study was to determine the impact of a multifaceted, community-wide intervention on overall antibiotic use for young children and on use of broad-spectrum agents. In addition, we sought to compare the intervention's impact on commercially and Medicaid-insured children., Methods: We conducted a controlled, community-level, cluster-randomized trial in 16 nonoverlapping Massachusetts communities, studied from 1998 to 2003. During 3 years, we implemented a physician behavior-change strategy that included guideline dissemination, small-group education, frequent updates and educational materials, and prescribing feedback. Parents received educational materials by mail and in primary care practices, pharmacies, and child care settings. Using health-plan data, we measured changes in antibiotics dispensed per person-year of observation among children who were aged 3 to <72 months, resided in study communities, and were insured by a participating commercial health plan or Medicaid., Results: The data include 223,135 person-years of observation. Antibiotic-use rates at baseline were 2.8, 1.7, and 1.4 antibiotics per person-year among those aged 3 to <24, 24 to <48, and 48 to <72 months, respectively. We observed a substantial downward trend in antibiotic prescribing, even in the absence of intervention. The intervention had no additional effect among children aged 3 to <24 months but was responsible for a 4.2% decrease among those aged 24 to <48 months and a 6.7% decrease among those aged 48 to <72 months. The intervention effect was greater among Medicaid-insured children and for broad-spectrum agents., Conclusions: A sustained, multifaceted, community-level intervention was only modestly successful at decreasing overall antibiotic use beyond substantial secular trends. The more robust impact among Medicaid-insured children and for specific medication classes provides an argument for specific targeting of resources for patient and physician behavior change.

Background: One approach to improving outcomes for minority diabetics may be through better self-care. However, minority patients may encounter barriers to better self-care even within settings where variations in quality of care and insurance are minimized., Objective: The objective of the study was to evaluate racial differences in long-term glucose self-monitoring and adherence rates in an HMO using evidence-based guidelines for self-monitoring., Design: Retrospective cohort study using 10 years (1/1/1993-12/31/2002) of electronic medical record data was used., Patients: Patients were 1,732 insured adult diabetics of black or white race newly initiated on hypoglycemic therapy in a large multi-specialty care group practice., Measurements: Outcomes include incidence and prevalence of glucose self-monitoring, intensity of use, and rate of adherence to national recommended standards., Results: We found no evidence of racial differences in adjusted initiation rates of glucose self-monitoring among insulin-treated patients, but found lower rates of initiation among black patients living in low-income areas. Intensity of glucose self-monitoring remained lower among blacks than whites throughout follow-up [IRR for insulin = 0.41 (0.27-0.62); IRR for oral hypoglycemic = 0.75 (0.63, 0.90)], with both groups monitoring well below recommended standards. Among insulin-treated patients, <1% of blacks and <10% of whites were self-monitoring 3 times per day; 36% of whites and 10% of blacks were self-monitoring at least once per day., Conclusions: Adherence to glucose self-monitoring standards was low, particularly among blacks, and racial differences in self-monitoring persisted within a health system providing equal access to services for diabetes patients. Early and continued emphasis on adherence among black diabetics may be necessary to reduce racial differences in long-term glucose self-monitoring.

Background: Insurance coverage of patient self-management devices like self-monitoring blood glucose (SMBG) equipment may help to reduce race-related barriers to effective care., Objectives: We examined whether providing free home glucose monitors had greater impacts on self-monitoring among black versus white patients with diabetes., Research Design: Using electronic medical record data (1992-1996), we used longitudinal survival analysis to examine racial differences in rates of initiation of SMBG after coverage and rates of discontinuation of SMBG 18 months after initiation. We used piecewise Cox models to compare relative rates of SMBG initiation between black and white patients before and after the policy., Subjects: The study cohort included 2275 continuously enrolled adult patients with diabetes in a large, staff model HMO. Multivariate models were restricted to patients using oral therapy., Results: Controlling for time-dependent and fixed effects, black patients were as likely to initiate SMBG as white patients before the policy (hazard ratio 1.14; 95% confidence interval 0.86-1.50) but more likely after the policy (hazard ratio 1.33; 95% confidence interval 1.01-1.76). Among postpolicy SMBG initiators, black patients were consistently at higher risk of SMBG discontinuation than white patients over time (P < 0.05). By the end of follow-up, discontinuation rates were 78% among black patients and 64% among white patients., Conclusions: The policy is effective in triggering additional diabetes patients to self-manage, particularly black patients. However, persistence after initiation of monitoring is short-lived. Although our results show the potential of such policies to narrow racial gaps in self-management among racial minority groups, further interventions may be needed to promote long-term adherence.

Background: Racial disparities in care are well documented; information regarding solutions is limited. We evaluated whether generic quality improvement efforts were associated with changes in racial disparities in diabetes care., Methods: Using insurance claims and electronic medical record data, we identified 5101 whites and 1987 blacks with diabetes mellitus receiving care within a multispecialty group practice from 1997 to 2001. We assessed rates of annual low-density lipoprotein cholesterol level testing, low-density lipoprotein cholesterol level control (<130 mg/dL [<3.37 mmol/L]), statin therapy, annual glycosylated hemoglobin level testing, glycosylated hemoglobin level control (<7.0%), and annual dilated eye examinations. We used logistic regression models with generalized estimating equations to adjust for race, year, race x year interactions, age, and sex., Results: Rates of annual low-density lipoprotein cholesterol level testing increased from 39% to 64%, while the white-black disparity decreased from 14% to 4%; rates of low-density lipoprotein cholesterol level control increased from 15% to 43%, while the white-black disparity decreased from 9% to 6% (P<.001 for both race x year interactions). Statin therapy rates increased from 20% to 37%; however, black patients remained less likely than white patients to receive therapy. The 1997 rates of annual glycosylated hemoglobin level testing (76%) and annual eye examinations (74%) were high, and there was no white-black disparity over time. Rates of glycosylated hemoglobin level control remained low (31%), and the white-black disparity remained constant at 10%., Conclusions: Racial disparities were diminished in some aspects of diabetes care following variably successful quality improvement, but differences in the use of statins and glycemic level control persisted. Reducing disparities may require a focus on minority health.

Objective: We examined race differences in diabetes outcomes over 4-8 years in a single HMO., Research Design and Methods: We identified black and white adult diabetic patients who were continuously enrolled (1992-2001) and in whom diabetes was 1) diagnosed before 1994 (n = 1,686) or 2) newly diagnosed in 1994-1997 (n = 1,280). We used hierarchical models to estimate the effect of race on average annual HbA(1c) (A1C) controlling for baseline A1C, BMI, and age, as well as annual measures of type of diabetes medications, diabetes-related hospitalization, time and the number of A1C tests, physician visits, and nondiabetes medications. Stratifying by sex accounted for significant interactions between sex and race., Results: At baseline, black and white patients had similar rates of A1C testing and physician visits, but blacks had higher unadjusted A1C values. In multivariate models, among patients with previously diagnosed diabetes, average A1C was nonsignificantly 0.11 higher (95% CI -0.12 to 0.34) in black than in white men but was 0.30 higher (0.14-0.46; P = 0.0007) in black than in white women. Among patients with newly diagnosed diabetes, the adjusted black-white gap was 0.49 among men (0.17-0.80; P = 0.007) and was 0.05 among women (-0.20 to -0.31), which was positive but not significant., Conclusions: Factors other than the quality of care may explain persistent race differences in A1C in this setting. Future interventions should target normalization of A1C by identifying potential psychosocial barriers to therapy intensification among patients and clinicians and development of culturally appropriate interventions to aid patients in successful self-management.

Objective: The purpose of this study was to evaluate the effects on breastfeeding rates of a private-sector early discharge program and a subsequent government mandate guaranteeing 48 hours of hospital coverage., Methods: Interrupted time-series analyses were conducted on retrospective data from the automated medical records of a large health maintenance organization in eastern Massachusetts. A population of 20 366 mother-infant pairs with normal vaginal deliveries between October 1990 and March 1998 was identified. This study period spanned the 2 interventions of interest: 1) the introduction of a new health maintenance organization protocol of 1 postpartum overnight hospitalization followed by a nurse home visit for normal vaginal deliveries, then 2) Massachusetts state minimum coverage legislation. Breastfeeding initiation and breastfeeding continuation among initiators (exclusive or with supplements) into the third month of life were determined through a text search of the first 90 days of infants' automated medical records., Results: Both policies had dramatic impacts on length of stay (LOS); postpartum LOS <2 nights rose from 29% of pairs to 65% when the early discharge program was implemented, then fell to 15% after the state mandate. Breastfeeding initiation, however, rose gradually from 71% in the fourth quarter of 1990 to 82% in the first quarter of 1998, with no changes after the interventions. Continuation of breastfeeding among those who initiated remained constant at 73%. Younger maternal age, primiparity, low socioeconomic status, and nonwhite race all were found to be risk factors for lower rates of breastfeeding (either initiation or continuation), but there was no evidence of a decline in breastfeeding associated with shorter LOS among these vulnerable groups., Conclusions: Early postpartum discharge with outpatient breastfeeding support and a home visitor program has no adverse effects on initiation or continuation of breastfeeding.

Background: Concern about harm to newborns from early postpartum discharges led to laws establishing minimum hospital stays in the mid-1990s. We evaluated the effects of an early-discharge protocol (a hospital stay of one postpartum night plus a home visit) in a health maintenance organization (HMO) and a subsequent state law guaranteeing a 48-hour hospital stay., Methods: Using interrupted-time-series analysis and data on 20,366 mother-infant pairs with normal vaginal deliveries, we measured changes in length of stay, newborn examinations on the third or fourth day of life, and office visits, emergency department visits, and hospital readmissions for newborns. We also examined expenditures for hospitalizations and home-based care., Results: The early-discharge program increased the rate of stays of less than two nights from 29.0 percent to 65.6 percent (P<0.001). The rate declined to 13.7 percent after the state mandate (P<0.001). The rate of newborn examinations on the third or fourth day of life increased from 24.5 percent to 64.4 percent with the program (P<0.001), then dropped to 53.0 percent after the mandate (P<0.001)--changes that primarily reflected changes in the rate of home visits. The rate of nonurgent visits to a health center increased from 33.4 percent to 44.7 percent (P<0.001) after the reduced-stay program was implemented. There were no significant changes in the rate of emergency department visits (quarterly mean, 1.1 percent) or rehospitalizations (quarterly mean, 1.5 percent). Results were similar for a vulnerable subgroup with lower incomes, younger maternal age, a lower level of education, or some combination of these characteristics. Average HMO expenditures on hospital and home-based services decreased by $90 per delivery with the early-discharge program and increased by $100 after the mandate., Conclusions: Neither policy appears to have affected the health outcomes of newborns. After the mandate, newborns were less likely to be examined as recommended on day 3 or 4. Because of changes in hospital prices, the two policies had minimal effects on HMO expenditures for hospital and home-based services., (Copyright 2002 Massachusetts Medical Society)

Objective: To determine whether brief, face-to-face educational outreach visits can improve the appropriateness of blood product utilization., Design: Randomized, controlled multicenter trial with 6-month follow-up., Setting: Surgical and medical services of two pairs of matched community and teaching hospitals in Massachusetts., Participants: One hundred one transfusing staff surgeons and attending medical physicians., Intervention: A professionally based transfusion specialist presented one surgical- or medical-service-wide lecture emphasizing appropriate indications, risks, and benefits of red blood cell transfusions; brief, graphic, printed educational guidelines; and one 30-minute visit with each transfusing physician. No data feedback was provided. Educational messages emphasized the lack of utility of the traditional threshold for red blood cell transfusions (hematocrit, 30%) and transfusion risks (eg, viral hepatitis)., Measures: Proportion of red blood cell transfusions classified as compliant or noncompliant with blood transfusion guidelines, or indeterminate 6 months before and 6 months after an experimental educational intervention., Results: Based on analyses of 1449 medical record audits of red blood cell transfusions that occurred 6 months before and 6 months after the educational intervention, the average proportion of transfusions not in compliance with criteria declined from 0.40 to 0.24 among study surgeons (-40%) compared with an increase from 0.40 to 0.44 (+9%) among control surgeons (P = .006). These effects were consistent across procedure type and specialty. On average, study surgeons in the postintervention period performed transfusions when hematocrits were 2.0 percentage points lower than before the intervention (28.3% preintervention vs 26.3% postintervention), and lower than in the control group (28.3% preintervention and postintervention; P = .04). Likely savings in blood use for surgical services probably exceeded program costs, even without considering reduced risks of infection. No effects were observed among transfusions occurring in medical services, possibly because of substantially lower transfusion rates and lower pretransfusion hematocrits., Conclusions: Brief, focused educational outreach visits by transfusion specialists can substantially improve the appropriateness and cost-effectiveness of blood product use in surgery. More data are needed regarding the durability of changes in practice patterns and the health and economic benefits of such interventions.
