The Contribution of Insurance Coverage and Community Resources to Reducing Racial/Ethnic Disparities in Access to Care

OBJECTIVE To examine the extent to which health insurance coverage and available safety net resources reduced racial and ethnic disparities in access to care. DATA SOURCES Nationally representative sample of 11,692 African American, 10,325 Hispanic, and 74,397 white persons. Nonelderly persons with public or private health insurance and those who were uninsured. STUDY DESIGN Two cross-sectional surveys of households conducted during 1996-1997 and 1998-1999. DATA COLLECTION Commonly used measures of access to and utilization of medical care were constructed for individuals. These measures include the following. (1) percent reporting unmet medical needs, (2) percent without a regular health care provider, and (3) no visit with a physician in the past year. FINDINGS More than 6.5 percent of Hispanic and African Americans reported having unmet medical needs compared to less than 5.6 percent of white Americans. Hispanics were least likely to see the same doctor at their usual source of care (59 percent), compared to African Americans (66 percent) and whites (75 percent). Similarly, Hispanics were less likely than either African Americans or whites to have seen a doctor in the last year (65 percent compared to 76 percent or 79 percent). For Hispanics, more than 80 percent of the difference from whites was due to differences in measured characteristics (e.g., insurance coverage, income, and available safety net services). Differences in measured characteristics between African Americans and whites explained less than 80 percent of the access disparities. CONCLUSION Lack of health insurance was the single most important factor in white-Hispanic differences for all three measures and for two of the white-African American differences. Income differences were the second most important factor, with one exception. Community characteristics generally were much less important, with one exception. The positive effects of insurance coverage in reducing disparities outweigh benefits of increasing physician charity care or access to emergency rooms.

Adjusting for patient characteristics when analyzing reports from patients about hospital care.

Objectives.To determine which patient characteristics are associated with reports and ratings of hospital care, and to evaluate how adjusting reports and ratings for hospital differences in such variables affects comparisons among hospitals. Design.A telephone survey of a sample of patients hospitalized in 22 hospitals in a single city and a statewide mail survey of hospitalized patients. Measures.The surveys assessed: respect for patients’ preferences, coordination of care, information exchange between patient and providers, physical care, emotional support, involvement of family and friends, and transition and continuity. The surveys also asked patients to rate their doctors, nurses, and other hospital staff. Results.The variables with the strongest and most consistent associations with patient-reported problems were age and reported health status. Patient gender and education level also sometimes predicted reports and/or ratings. Models including these variables explained only between 3% and 8% of the variation in reports and ratings. Conclusions.The impact of adjusting for patient characteristics on hospital rankings was small, although a larger impact would be expected when comparing hospitals with more variability in types of patients. Nevertheless, we recommend adjusting at least for the most important predictors, such as age and health status. Such adjustment helps alleviate concerns about bias. It also may be useful to present data for certain groups of patients (ie, medical, surgical, obstetric) separately to facilitate interpretation and quality improvement efforts.

Managed care, professional autonomy, and income: effects on physician career satisfaction.

AbstractCONTEXT: Career satisfaction among physicians is a topic of importance to physicians in practice, physicians in training, health system administrators, physician organization executives, and consumers. The level of career satisfaction derived by physicians from their work is a basic yet essential element in the functioning of the health care system. OBJECTIVE: To examine the degree to which professional autonomy, compensation, and managed care are determinants of career satisfaction among physicians. DESIGN: Cross-sectional analysis using data from 1996–97 Community Tracking Study physician telephone survey. SETTING AND PARTICIPANTS: A nationally representative sample of 12,385 direct patient care physicians. The survey response rate was 65%. MAIN OUTCOME MEASURE: Overall career satisfaction among U.S. physicians. RESULTS: Bivariate results show that physicians with low managed care revenues are significantly more likely to be “very satisfied” than are physicians with high managed care revenue (P<.05), and that physicians with low managed care revenues are significantly more likely to report higher levels of clinical freedom than are physicians with high managed care revenue (P<.05). Multivariate analyses demonstrate that, among our measures, traditional core professional values and autonomy are the most important determinants of career satisfaction after controlling for all other factors. Relative income is also an important independent predictor. Multiple dimensions of professional autonomy hold up as strong, independent predictors of career satisfaction, while the effect of managed care does not. Managed care appears to exert its effect on satisfaction through its impact on professional autonomy, not through income reduction. CONCLUSIONS: Our results suggest that when managed care (or other influences) erode professional autonomy, the result is a highly negative impact on physician career satisfaction.

Performance quality, gender, and professional role: A study of physicians and nonphysicians in 16 ambulatory care practices

The quality of medical care has rarely been evaluated in relation to practitioner or patient gender. Moreover, comparisons between physicians and nonphysicians typically are confounded by practitioner gender. In this study gender and professional role effects were analyzed separately for 162 male and female staff physicians, 191 male and female residents, and 73 female nonphysicians delivering adult and pediatric primary care in 16 ambulatory care practices. Analyses addressed influences of patient and practitioner gender as well as differences between physicians and nonphysicians. Results showed that female staff physicians performed better than male staff physicians for cancer screening in women by breast examination and Pap smears, but that female residents performed worse than male residents for urinary tract infections in children. Patient gender effects occurred for two tasks; for these, superior care was rendered to the gender with higher prevalence for the condition (girls for urinary tract infections, boys for otitis media). The results are considered in the context of the gender-relevance of particular medical tasks or conditions. Comparisons between physicians and nonphysicians were limited to female practitioners. Comparable or superior performance for nonphysicians was found for all tasks but one (cancer screening in women).

Patient-centered processes of care and long-term outcomes of myocardial infarction

OBJECTIVE: To examine whether patients’ experiences with nontechnical aspects of care such as patient education and discharge planning are associated with long-term outcomes.DESIGN: Observational cohort study.SETTING: Twenty-three New Hampshire hospitals during 1996 and 1997.PARTICIPANTS: Acute myocardial infarction (AMI) patients (N=2,272) enrolled prior to discharge.MEASUREMENTS: Surveys asking about problems with care and health were mailed to patients 1, 3, and 12 months after discharge. Patients were stratified into “worse” or “better” care groups on the basis of their hospital care problem score. Outcomes included self-reported overall health, physical health, mental health, chest pain, and shortness of breath. Other clinical measures were obtained from hospital discharge abstracts.MAIN RESULTS: The 1-, 3-, and 12-month surveys were returned by 1,346 (59.2%), 1,046 (46%), and 964 (42.4%) enrolled patients, respectively. The primary analytic cohort consisted of the 762 patients who completed both the 1- and 12-month surveys. After adjustment for postdischarge health status and other clinical factors, patients experiencing worse hospital care had lower ratings of overall health (48.4 vs 52.5 on 100-point scale; P=.02) and physical health (59.7 vs 68.4; P<.001), and were more likely to have chest pain (odds ratio [OR], 1.6; confidence interval [CI], 1.0 to 2.4; P=.04) 12 months after their AMI than other patients. However, differences in reports of chest pain were reduced if patients reporting worse hospital care had better experiences with subsequent ambulatory care.CONCLUSIONS: Patients’ experiences with nontechnical processes of AMI hospital care are associated with long-term outcomes; however the association between a negative hospital experience and subsequent chest pain may be offset by more positive outpatient experiences.

Screening for Childhood Trauma in Adult Primary Care Patients: A Cross-Sectional Survey

OBJECTIVE Compared to screening for partner violence, screening for childhood physical and sexual abuse among adult patients has received little attention, despite associated adverse health consequences. The objective of this exploratory study was to describe the practices, skills, attitudes, and perceived barriers of a large sample of family physicians in screening adult patients for childhood sexual or physical abuse. METHOD Surveys were mailed to the 833 members of the Massachusetts Academy of Family Physicians in 2007 eliciting information about screening practices. Factors associated with routine or targeted screening among adult primary care patients were evaluated. RESULTS Less than one-third of providers reported usually or always screening for childhood trauma and correctly estimated childhood abuse prevalence rates; 25% of providers reported that they rarely or never screen patients. Confidence in screening, perceived role, and knowledge of trauma prevalence were associated with routine and targeted screening. Women and physicians reporting fewer barriers were more likely to routinely screen adult patients. CONCLUSIONS Despite the 20%-50% prevalence of child abuse exposure among adult primary care patients, screening for childhood abuse is not routine practice for most physicians surveyed; a large subgroup of physicians never screen patients. Study findings draw attention to a largely unexplored experience associated with considerable health care costs and morbidity. Results highlight the need to develop training programs about when to suspect trauma histories and how to approach adult patients.

Are population-based diabetes models useful for individual risk estimation

Background:Predictive models are increasingly used in guidelines and informed decision-making interventions. We compared predictions from 2 prominent models for diabetes: the United Kingdom Prospective Diabetes Study (UKPDS) outcomes model and the Archimedes-based Diabetes Personal Health Decisions (PHD) model. Methods:Ours was a simulation study comparing 10-year and 20-year model predictions for risks of myocardial infarction (MI), stroke, amputation, blindness, and renal failure for representative test cases. Results:The Diabetes PHD model predicted substantially higher risks of MI and stroke in most cases, particularly for stroke and for 20-year outcomes. In contrast, the UKPDS model predicted risks of amputation and blindness ranging from 2-fold to infinitely higher than the Diabetes PHD model. Predictions for renal failure all differed by more than 2-fold but in a complicated pattern varying by time frame and specific risk factors. Relative to their predictions for white men, the UKPDS model predicted much lower MI and stroke risks for women and Afro-Caribbean men than the Diabetes PHD model did for women and black men. A substantial majority of the Diabetes PHD point estimates fell outside of the UKPDS outcomes models 95% CIs. Conclusions:These models produced markedly different predictions. Patients and providers considering risk estimates from such models need to understand their substantial uncertainty and risk of misclassification.

A randomized controlled trial of community health workers using patient stories to support hypertension management: Study protocol

BACKGROUND Uncontrolled hypertension is a significant public health problem in the U.S. with about one half of people able to keep blood pressure (BP) under control. Uncontrolled hypertension leads to increased risk of stroke, heart attack, and death. Furthermore, the social and economic costs of poor hypertension control are staggering. People living with hypertension can benefit from additional educational outreach and support. METHODS This randomized trial conducted at two Community Health Centers (CHCs) in Massachusetts assessed the effect of community health workers (CHWs) assisting patients with hypertension. In addition to the support provided by CHWs, the study uses video narratives from patients who have worked to control their BP through diet, exercise, and better medication adherence. Participants enrolled in the study were randomly assigned to immediate intervention (I) by CHWs or a delayed intervention (DI) (4 to 6 months later). Each participant was asked to meet with the CHW 5 times (twice in person and three times telephonically). Study outcomes include systolic and diastolic BP, diet, exercise, and body mass index. CONCLUSION CHWs working directly with patients, using multiple approaches to support patient self-management, can be effective agents to support change in chronic illness management. Moreover, having culturally appropriate tools, such as narratives available through videos, can be an important, cost effective aid to CHWs. Recruitment and intervention delivery within a busy CHC environment required adaptation of the study design and protocols for staff supervision, data collection and intervention delivery and lessons learned are presented.
