Low-cost insulin for socially at-risk patients: evidence for effectiveness.

OBJECTIVES: The price of analogue insulin has increased dramatically, making it unaffordable for many patients and insurance carriers. By contrast, human synthetic insulins are available at a fraction of the cost. The objective of this study was to examine whether patients with financial constraints were more likely to use low-cost human insulins compared with higher-cost analogue insulins and to determine whether outcomes differ between users of each type of insulin. STUDY DESIGN: Retrospective cohort study. METHODS: Analysis of 4 cycles of the National Health and Nutrition Examination Survey was performed. Adults with diabetes who reported use of insulin were included. The primary outcome was use of human insulin or analogue insulin. The dependent variable was self-reported financial constraints, a composite variable. Secondary analysis examined the association between use of human vs analogue insulin and patient outcomes. RESULTS: Of 22,263 eligible respondents, 698 (3.1%) reported use of insulin and the type of insulin used, representing 485,228 patients nationally. Patients with 1 or more financial risk factors were more likely to use human insulin compared with patients without any financial risk factors (88.5% vs 76.7%; P = .014). There was no association between use of human vs analogue insulin on diabetic or other patient outcomes among patients regardless of financial risk. CONCLUSIONS: Patients with financial risk factors may be more likely to use low-cost human synthetic insulins compared with insulin analogues. Outcomes were similar, even when stratified by financial risk.

Impact of care coordination based on insurance and zip code.

OBJECTIVES: To examine whether a care transitions program, Bridges, differentially reduced rehospitalizations among patients who underwent percutaneous coronary intervention (PCI) based on insurance status and zip code poverty level. STUDY DESIGN: Retrospective observational cohort. METHODS: We examined data from a single health system in Delaware, collected as part of a care transitions program for patients who underwent PCI from 2012 to 2015 compared with an unmatched historical control cohort from 2010 to 2011. Socioeconomic status was assessed by insurance status and zip code-level poverty data. Patients were divided into tertiles based on the proportion of their zip code of residence living under 100% of the federal poverty level. Rehospitalization rates were analyzed by negative binomial regression and included interaction terms to examine differential effects of Bridges by insurance and poverty level. RESULTS: There were 4638 patients representing 5710 hospitalizations: 3212 in the historical control and 2498 in the Bridges cohort. Among patients with Medicaid who received the Bridges intervention, those living in the wealthiest zip codes were 15.5% less likely to be rehospitalized than patients with Medicare and 9.4% less likely than patients with commercial insurance (P = .04). However, patients with Medicaid who lived in the poorest zip codes and those with dual Medicare/Medicaid status had higher rates of rehospitalization post intervention. CONCLUSIONS: The Bridges intervention was associated with improved rehospitalization rates for Medicaid patients compared with those with Medicare or commercial insurance within Delaware's wealthier communities. Care transitions programs may differentially affect Medicaid patients based on the wealth of the communities in which they reside.

"Implications of cost-sharing for observation care among Medicare beneficiaries: a pilot survey".

BACKGROUND: Medicare beneficiaries hospitalized under observation status have significant cost-sharing responsibilities under Medicare Part B. Prior work has demonstrated an association between increased cost-sharing and health care rationing among low-income Medicare beneficiaries. The objective of this study was to explore the potential impact of observation cost-sharing on future medical decision making of Medicare beneficiaries. METHODS: Single-center pilot cohort study. A convenience sample of Medicare beneficiaries hospitalized under observation status care was surveyed. RESULTS: Out of 144 respondents, low-income beneficiaries were more likely to be concerned about the cost of their observation stay than higher-income respondents (70.7% vs29.3%, p = 0.015). If hospitalized under observation status again, there was a trend among low-income beneficiaries to request completion of their workup outside of the hospital (56.3% vs 43.8%), and to consider leaving against medical advice (AMA) (100% vs 0%), though these trends were not statistically significant (p = 0.30). CONCLUSION: The results of this pilot study suggest that low-income Medicare beneficiaries hospitalized under observation status have greater concerns about their cost-sharing obligations than their higher income peers. Cost-sharing for observation care may have unintended consequences on utilization for low-income beneficiaries. Future studies should examine this potential relationship on a larger scale.

Observation Status, Poverty, and High Financial Liability Among Medicare Beneficiaries.

BACKGROUND: Medicare beneficiaries hospitalized under observation status are subject to cost-sharing with no spending limit under Medicare Part B. Because low-income status is associated with increased hospital use, there is concern that such beneficiaries may be at increased risk for high use and out-of-pocket costs related to observation care. Our objective was to determine whether low-income Medicare beneficiaries are at risk for high use and high financial liability for observation care compared with higher-income beneficiaries. METHODS: We performed a retrospective, observational analysis of Medicare Part B claims and US Census Bureau data from 2013. Medicare beneficiaries with Part A and B coverage for the full calendar year, with 1 or more observation stay(s), were included in the study. Beneficiaries were divided into quartiles representing poverty level. The associations between poverty quartile and high use of observation care and between poverty quartile and high financial liability for observation care were evaluated. RESULTS: After multivariate adjustment, the risk of high use was higher for beneficiaries in the poor (Quartile 3) and poorest (Quartile 4) quartiles compared with those in the wealthiest quartile (Quartile 1) (adjusted odds ratio [AOR], 1.21; 95% confidence interval [CI], 1.13-1.31; AOR, 1.24; 95% CI, 1.16-1.33). The risk of high financial liability was higher in every poverty quartile compared with the wealthiest and peaked in Quartile 3, which represented the poor but not the poorest beneficiaries (AOR, 1.17; 95% CI, 1.10-1.24). CONCLUSIONS: Poverty predicts high use of observation care. The poor or near poor may be at highest risk for high liability.

The Unmet Need for Postacute Rehabilitation Among Medicare Observation Patients: A Single-Center Study.

BACKGROUND: Medicare beneficiaries admitted under observation status must pay for postacute inpatient rehabilitation (PAIR) services, out of pocket, at potentially prohibitive costs. OBJECTIVE: To determine if there is an unmet need for PAIR among Medicare observation patients and if this care is associated with longer hospital stay and increased rehospitalization. DESIGN/SETTING: Observational study using electronic medical record and administrative data from a regional health system. PATIENTS: 1323 community-dwelling Medicare patients admitted under observation status. MEASUREMENTS: Summary statistics were calculated for demographic and administrative variables. Physical therapy (PT) and case management recommendations for a representative sample of 386 medical records were reviewed regarding need for PAIR services. Linear regression was used to measure the association between PT recommendation and hospital length of stay, adjusting for ICD-9 (International Classification of Diseases, Ninth Revision) diagnosis, age, sex, and provider. Chi-square test was used to determine the association between PT recommendation and 30-day hospital revisit. RESULTS: Of the 1323 study patients, 11 (0.83%) were discharged to PAIR facilities. However, 17 (4.4%) of the 386 patients whose charts were reviewed received a recommendation for this care. Adjusted mean hospital stay was longer (P ⟨ 0.001) for patients recommended for rehabilitation (75.9 h) than for patients with no PT needs (46.8 h). In addition, the 30-day hospital revisit rate was higher (P = 0.037) for the patients who had been recommended for rehabilitation (52.9%, 9/17) than for those who had not (25.4%, 30/118). CONCLUSIONS: Medicare observation patients' potential need for PAIR services is 5- to 6-fold higher than their use of these services. Observation patients recommended for this care may have worse outcomes. Journal of Hospital Medicine 2017;12:168-172.

Improved quality of care for cardiovascular disease for Latinos seen in high proportion Latino vs low proportion Latino clinics.

BACKGROUND: Primary care practices that concentrate linguistically and culturally appropriate services for Latinos may result in higher cardiology consultation rates and improved process measure performance for patients with coronary artery disease (CAD) and congestive heart failure (CHF). METHODS: Multivariable Cox proportional-hazards regression was used to assess differences in referral at high proportion (HP) vs low proportion (LP) practices. Multivariable Poisson regression was used to assess the frequency of follow-up consultation. RESULTS: Among the 9,761 patients, 9,168 had CAD, 4,444 had CHF, and 3,851 had both conditions. Latinos comprised 11% of the CAD cohort and 11% of the CHF cohort. Multivariable analyses showed higher consultation rates for Latinos at HP practices for CAD and CHF. Blacks and Whites at HP practices had no significant differences in rates of consultation compared to those in LP practices. Latinos at HP practices had 25% more consultations for CAD and 23% more consultations for CHF than Latinos at LP practices. Latinos at HP clinics had higher overall mean quality performance on clinical measures for both CAD and CHF. Latinos at an LP clinic had the largest improvement in quality performance with consultation. CONCLUSIONS: Among Latinos with CAD or CHF receiving care within a single large academic care network, Latino patients at HP practices have higher rates of cardiologist consultation and performance on CVD process measures compared to Latino patients at LP practices. Elucidating the essential components of individual practice environments that provide higher quality of care for Latinos will allow for well designed systems to reduce health care disparities.

Use of interpreters by physicians for hospitalized limited English proficient patients and its impact on patient outcomes.

BACKGROUND: Few studies have examined the impact of inpatient interpreter use for limited English proficient (LEP) patients on length of stay (LOS), 30-day post discharge emergency department (ED) visits and 30-day hospital readmission rates for LEP patients. METHODS: A retrospective cohort analysis was conducted of all hospitalized patients admitted to the general medicine service at a large academic center. For patients self-reported as LEP, use of interpreters during each episode of hospitalization was categorized as: 1) interpreter used by non-MD (i.e., nurse); 2) interpreter used by a non-Hospitalist MD; 3) interpreter used by Hospitalist; and 4) no interpreter used during hospitalization. We examined the association of English proficiency and interpreter use on outcomes utilizing Poisson and logistic regression models. RESULTS: Of 4,224 patients, 564 (13 %) were LEP. Of these LEP patients, 65.8 % never had a documented interpreter visit, 16.8 % utilized an interpreter with a non-MD, 12.6 % utilized an interpreter with a non-Hospitalist MD and 4.8 % utilized an interpreter with a hospitalist present. In adjusted models, compared to English speakers, LEP patients with no interpreters had significantly shorter LOS. There were no differences in readmission rates and ED utilization between LEP and English-speaking patients. Compared to LEP patients with no interpreter use, those who had a physician use an interpreter had odds for a longer LOS, but there was no difference in odds of readmission or ED utilization. CONCLUSION: Academic hospital clinician use of interpreters remains highly variable and physicians may selectively be using interpreters for the sickest patients.

Assessing the need for improved access to rheumatology care: a survey of Massachusetts community health center medical directors.

OBJECTIVE: Access to rheumatology care can expedite diagnosis and treatment of rheumatic diseases and reduce disparities. We surveyed community health center (CHC) medical directors to evaluate rheumatology care in underserved areas and potential strategies for improvement. METHODS: We identified 77 Massachusetts CHCs that provide adult medical services and sent a 40-item survey to their physician medical directors. Survey questions assessed the centers' prevalence of rheumatic diseases, prescribing practices of immunosuppressive medications, and possible interventions to improve care. We compared CHC characteristics and rheumatology-specific items and then stratified our data by the response to whether improved access to rheumatology care was needed. Qualitative data were analyzed thematically. RESULTS: Thirty-six CHC physician medical directors returned surveys (47% response rate). Fifty-five percent indicated a need for better access to rheumatology care. Eighty-six percent of CHC physicians would not start a patient with rheumatoid arthritis on a disease-modifying antirheumatic drug; 94% would not start a patient with systemic lupus erythematosus on an immunosuppressant. When we compared CHCs that reported needing better access to rheumatology care to those that did not, the former described a significantly greater percentage of patients with private insurance or Medicaid who required outside rheumatology referrals (P < 0.05). Language differences and insurance status were highlighted as barriers to obtaining rheumatology care. Sixteen directors (57%) ranked the patient navigator-a layperson to assist with care coordination-as their first-choice intervention. CONCLUSIONS: Community health center medical directors expressed a need for better access to rheumatology services. A patient navigator for rheumatic diseases was proposed to help improve care and reduce health disparities.

A systematic review of community-based participatory research to enhance clinical trials in racial and ethnic minority groups.

OBJECTIVE: To examine the effectiveness of current community-based participatory research (CBPR) clinical trials involving racial and ethnic minorities. DATA SOURCE: All published peer-reviewed CBPR intervention articles in PubMed and CINAHL databases from January 2003 to May 2010. STUDY DESIGN: We performed a systematic literature review. DATA COLLECTION/EXTRACTION METHODS: Data were extracted on each study's characteristics, community involvement in research, subject recruitment and retention, and intervention effects. PRINCIPLE FINDINGS: We found 19 articles meeting inclusion criteria. Of these, 14 were published from 2007 to 2010. Articles described some measures of community participation in research with great variability. Although CBPR trials examined a wide range of behavioral and clinical outcomes, such trials had very high success rates in recruiting and retaining minority participants and achieving significant intervention effects. CONCLUSIONS: Significant publication gaps remain between CBPR and other interventional research methods. CBPR may be effective in increasing participation of racial and ethnic minority subjects in research and may be a powerful tool in testing the generalizability of effective interventions among these populations. CBPR holds promise as an approach that may contribute greatly to the study of health care delivery to disadvantaged populations.

Health disparities and the criminal justice system: an agenda for further research and action.

Although racial and ethnic minorities are more likely to be involved with the criminal justice system than whites in the U.S.A., critical scientific gaps exist in our understanding of the relationship between the criminal justice system and the persistence of racial/ethnic health disparities. Individuals engaged with the criminal justice system are at risk for poor health outcomes. Furthermore, criminal justice involvement may have direct or indirect effects on health and health care. Racial/ethnic health disparities may be exacerbated or mitigated at several stages of the criminal justice system. Understanding and addressing the health of individuals involved in the criminal justice system is one component of a comprehensive strategy to reduce population health disparities and improve the health of our urban communities.

Insurance status and hospital care for myocardial infarction, stroke, and pneumonia.

BACKGROUND: Despite widely documented variations in health care outcomes by insurance status, few nationally representative studies have examined such disparities in the inpatient setting. OBJECTIVE: To determine whether there are insurance-related differences in hospital care for 3 common medical conditions. DESIGN AND SUBJECTS: Retrospective database analysis of 154,381 adult discharges (age 18-64 years) with a principal diagnosis of acute myocardial infarction (AMI), stroke, or pneumonia from the 2005 Nationwide Inpatient Sample (NIS). MEASUREMENTS: For each diagnosis, we compared in-hospital mortality, length of stay (LOS), and cost per hospitalization for Medicaid and uninsured patients with the privately insured. RESULTS: Compared with the privately insured, in-hospital mortality among AMI and stroke patients was significantly higher for the uninsured (adjusted odds ratio [OR] 1.52, 95% confidence interval [CI] [1.24-1.85] for AMI and 1.49 [1.29-1.72] for stroke) and among pneumonia patients was significantly higher for Medicaid recipients (1.21 [1.01-1.45]). Excluding patients who died during hospitalization, LOS was consistently longer for Medicaid recipients for all 3 conditions (adjusted ratio 1.07, 95% CI [1.05-1.09] for AMI, 1.17 [1.14-1.20] for stroke, and 1.04 [1.03-1.06] for pneumonia), although costs were significantly higher for Medicaid recipients for only 2 of the 3 conditions (adjusted ratio 1.06, 95% CI [1.04-1.09] for stroke and 1.05 [1.04-1.07] for pneumonia). CONCLUSIONS: In this nationally representative study of working-age Americans hospitalized for 3 common medical conditions, significantly lower in-hospital mortality was noted for privately insured patients compared with the uninsured or Medicaid recipients. Interventions to reduce insurance-related gaps in inpatient quality of care should be investigated.

Impact of health disparities collaboratives on racial/ethnic and insurance disparities in US community health centers.

BACKGROUND: The Health Resources and Services Administration Health Disparities Collaboratives (HDCs) were developed to improve care for chronic medical conditions in community health centers (CHCs). METHODS: We examined whether HDCs reduced disparities in quality by race/ethnicity or insurance status in CHCs nationally. We performed a controlled preintervention/postintervention study of 44 CHCs participating in HDCs for asthma, diabetes mellitus, or hypertension and 20 "external" control CHCs that had not participated. Each intervention center also served as an "internal" control for another condition. For each condition, we created an overall quality score, defined disparities in care as the differences in care between racial/ethnic groups and insurance groups, and examined changes in disparity through a series of hierarchical models using a 3-way interaction term among period, patient characteristics of interest, and treatment group. RESULTS: Overall, HDCs had little effect on disparities in composite measures for asthma, diabetes, and hypertension. For asthma care, collaborative centers had a baseline Hispanic-white disparity of 6.5%, which changed to a higher quality of recommended care for Hispanic patients over white patients by 0.8%, resulting in a significantly reduced Hispanic-white disparity compared with the change in disparity seen in external controls (P = .04). There were no other improvements in racial/ethnic or insurance disparities for any other conditions. CONCLUSIONS: Although HDCs are known to improve quality of care in CHCs, they had minimal effect on racial/ethnic and insurance disparities. In addition to targeting improvement in overall quality, future initiatives should include activities aimed at disparity reduction as an outcome.

Perspectives of non-Hispanic Black and Latino patients in Boston's urban community health centers on their experiences with diabetes and hypertension.

BACKGROUND: Racial/ethnic disparities exist in the prevalence and outcomes of diabetes and hypertension in the U.S. A better understanding of the health beliefs and experiences of non-Hispanic Blacks and Latinos with these diseases could help to improve their care outcomes. METHODS: We conducted eight focus groups stratified by participants' race/ethnicity, with 34 non-Hispanic Blacks and Latinos receiving care for diabetes and/or hypertension in one of 7 community health centers in Boston. Focus groups were designed to determine participants' levels of understanding about their chronic illness, assess their barriers to the management of their illness, and inquire about interventions they considered may help achieve better health outcomes. RESULTS: Among both groups of participants, nutrition (traditional diets), genetics and environmental stress (e.g. neighborhood crime and poor conditions) were described as primary contributors to diabetes and hypertension. Unhealthy diets were reported as being a major barrier to disease management. Participants also believed that they would benefit from attending groups on management and education for their conditions that include creative ways to adopt healthy foods that complement their ethnic diets, exercise opportunities, and advice on how to prevent disease manifestation among family members. CONCLUSIONS: Interactive discussion groups focused on lifestyle modification and disease management should be created for patients to learn more about their diseases. Future research evaluating the effectiveness of interactive diabetes and hypertension groups that apply patient racial/ethnic traditions should be considered.

Disparities in adherence to hypertensive care in urban ambulatory settings.

Nationally, a higher proportion of the medically underserved than of the general population suffer from hypertension. Poorer adherence to recommended therapies (including medication regimens, salt intake reduction, and regular visits with provider) has been linked to poorer blood pressure control. To identify whether differences in adherence are associated with racial/ethnic and socioeconomic characteristics, we administered a survey to 141 African American and non-Hispanic White hypertensive patients within two hospital-based clinics in an urban setting in the Northeast U.S. There were no differences in adherence to follow-up appointments or dietary recommendations between racial/ ethnic or income groups. However, there were differences between groups in adherence to medication regimens, with African Americans and lower-income groups significantly more likely to be non-adherent to medication regimens. When treating patients or implementing interventions aimed at improving adherence, special attention should be paid to African Americans and patients from low-income communities.

Part-time careers in academic internal medicine: a report from the association of specialty professors part-time careers task force on behalf of the alliance for academic internal medicine.

To establish guidelines for more effectively incorporating part-time faculty into departments of internal medicine, a task force was convened in early 2007 by the Association of Specialty Professors. The task force used informal surveys, current literature, and consensus building among members of the Alliance for Academic Internal Medicine to produce a consensus statement and a series of recommendations. The task force agreed that part-time faculty could enrich a department of medicine, enhance workforce flexibility, and provide high-quality research, patient care, and education in a cost-effective manner. The task force provided a series of detailed steps for operationalizing part-time practice; to do so, key issues were addressed, such as fixed costs, malpractice insurance, space, cross-coverage, mentoring, career development, productivity targets, and flexible scheduling. Recommendations included (1) increasing respect for work-family balance, (2) allowing flexible time as well as part-time employment, (3) directly addressing negative perceptions about part-time faculty, (4) developing policies to allow flexibility in academic advancement, (5) considering part-time faculty as candidates for leadership positions, (6) encouraging granting agencies, including the National Institutes of Health and Veterans Administration, to consider part-time faculty as eligible for research career development awards, and (7) supporting future research in "best practices" for incorporating part-time faculty into academic departments of medicine.

Strategies to improve chronic disease management in seven metro Boston community health centers.

BACKGROUND: The Community, Health Center, and Academic Medicine Partnership Project (CHAMPP) is a partnership between medical researchers, community health centers (CHCs), and a community advisory committee focused on reducing cardiovascular morbidity related to hypertension and diabetes for non-Hispanic Black and Hispanic populations in Boston, Massachusetts. OBJECTIVE: We conducted site visits at seven participating CHCs, located in Boston. The visits were to solicit health center staff opinions about site-specific barriers and enabling factors for optimum preventative cardiovascular care for racial/ethnic minority patients receiving hypertension and diabetes care at their centers. METHODS: Site visits included a tour of each health center and a series of directed interviews with center personnel. Site visit notes were reviewed to identify themes that emerged during the course of each site visit. A summary matrix was developed for each health center, which included information regarding the most salient and persistent themes of the visit. RESULTS: Site visits uncovered several patient-, provider-, CHC-, and community-based factors that either facilitate or hinder optimal care of chronic disease patients. Commonly referenced barriers included the need for improved patient adherence to provider recommendations; insufficient time for providers to address complex health issues presented by patients and the need for a broader range of healthier food options in surrounding communities. Interactive patient groups and community health workers (CHWs) have been well received when implemented. CONCLUSION: Recommendations included adopting case management as a part of usual care for chronic disease patients; additionally, widespread implementation of CHWs may to provide a platform for more comprehensive care for patients.

Differences in specialist consultations for cardiovascular disease by race, ethnicity, gender, insurance status, and site of primary care.

BACKGROUND: Consultation with cardiologists may improve the quality of ambulatory care and reduce disparities for patients with heart disease. We assessed the use of cardiology consultations and the associated quality by race/ethnicity, gender, insurance status, and site of care. METHODS AND RESULTS: In a retrospective cohort, we examined electronic records of 9761 adults with coronary artery disease or congestive heart failure (CHF) receiving primary care at practices affiliated with 2 academic medical centers during 2000 to 2005. During this period, 79.6% of patients with coronary artery disease and 90.3% of patients with CHF had a cardiology consultation. In multivariate analyses, women were less likely to receive a consultation than men for both conditions (coronary artery disease: hazard ratio, 0.89; 95% CI, 0.85 to 0.93; CHF: hazard ratio, 0.93; 95% CI, 0.87 to 0.99). Women also had 15% fewer follow-up consultations than men (P<0.001). Similarly, patients at community health centers were less likely to receive a consultation (coronary artery disease: hazard ratio, 0.79; 95% CI, 0.74 to 0.84; CHF: hazard ratio, 0.77; 95% CI: 0.71 to 0.84) and had 20% fewer follow-up consultations (P<0.001) relative to those at hospital-based practices. Black and Hispanic patients with CHF had 13% fewer follow-up consultations than white patients (P=0.01 and P=0.04, respectively). In adjusted analyses, consultation was associated with better processes of care compared with no consultation (P<0.001), particularly for women (P<0.001 for interaction between consultation and gender). CONCLUSIONS: Among ambulatory patients with coronary artery disease or CHF, women and those at community health centers have less access to cardiologists. Consultation is associated with better quality of care and narrows the gender gap in quality.
