Organizational and financial characteristics of health plans: are they related to primary care performance?

The effectiveness of a pay for performance program on diabetes care in Taiwan: A nationwide population-based longitudinal study

Over the past two decades, studies have widely examined the effectiveness of pay-for-performance (P4P) programs by conducting biochemical tests and assessing complications; however, the reported effectiveness of such programs among participants selected through purposeful sampling is controversial. Therefore, the objective of the current study was to analyze the effectiveness of a P4P program on patients' prognoses, including hospitalization for chronic diabetic complications, and all-cause mortality during specific follow-up years by using a nationwide population-based database in Taiwan. Based on 125,315 newly diagnosed type 2 diabetes patient cohort during 2002-2006, two control sets were designed by propensity-score-matching strategy according to participation of P4P program and followed up to 2012. The results indicated that full participants demonstrated the lowest risks of developing complications and all-cause mortality compared with nonparticipants. These findings confirm the long-term effect of P4P programs on full participants and reveal that this effect is not due to confounding variables. The results indicate the importance of performance management and adherence to interventions for patients with chronic diseases in a long-term observation. Comprehensive and continuous care is suggested to improve patient prognosis and quality of care.

Client perceptions of the performance of public and independent not-for-profit primary healthcare

Aims: To compare primary healthcare (PHC) provided by an independent not-for-profit organization (INPO) with that provided by two public municipal organizations (MO1 and MO2), in terms of clients' perceptions of performance, acceptance, and trust. Methods: A survey using a pre-tested questionnaire to all clients visiting a health centre (HC) doctor or nurse during one week in 2000 (n=511, 51% response rate) and 2002 (n=275, 47%). The data were analysed by descriptive statistics and cumulative logistic regression analysis. Results: The INPO differed from both publicly provided services in accessibility, consistency of service, and outcomes. Clients reported lower trust in HC provided by public organizations compared with the INPO. Trust was higher if clients also reported experiencing ``very good'' or ``moderate'' organizational access — or if general satisfaction was ``very high'' or ``moderate'' or if they experienced outcomes as ``very good'' or ``moderate'' compared with the ``very poor or low'' situation. Women reported lower trust in HC than men. When the family doctor was included in the same logistic regression model with the service provider, only the family doctor was a significant explanatory variable. Reported acceptance of private alternative service providers among clients was similar between the study organizations. Conclusions: Clients of the INPO generally rated the service more positively than clients of publicly provided services. The results indicate that trust in HC depends more on a family doctor system than a service provider.

Managed Care and Patient-Rated Quality of Care from Primary Physicians

The aim is to determine the associations between managed care controls and patient-rated quality of care from primary physicians. In a prospective cohort study, 17,187 patients were screened in the waiting rooms of 261 primary care physicians in the Seattle metropolitan area (1996-1997) to identify 2,850 English-speaking adult patients with depressive symptoms and/or selected pain problems. Patients completed 6-month follow-ups to rate the quality of care from their primary physicians. The intensity of managed care was measured for each patient’s health plan, primary care office, and physician. Regression analyses revealed that patients in more managed plans and offices had lower ratings of the quality of care from their primary physicians. Managed care controls targeting physicians were generally not associated with patient ratings.

Are Managed Care Medicare Beneficiaries With Chronic Conditions Satisfied With Their Care?

OBJECTIVES

This article compares patient experiences of chronically ill older people in health maintenance organizations (HMOs) with other forms of Medicare supplemental coverage.

METHOD

Using data from the 1996 Medicare Current Beneficiaries Survey, the authors analyzed the experiences of chronically ill elderly with overall quality, access to care, and physicians' technical, interpersonal, and information-giving skills. Logistic models controlled for prevalent chronic conditions, functioning, perceived health status, sociodemographics, region of residence, and county-level Medicare HMO penetration.

RESULTS

Satisfaction with quality of overall care and physicians' skills was more likely for many conditions for those with private fee for service and Medicaid supplemental coverage, compared to Medicare HMO population. No insurance effects were found among elders who had none of the examined conditions.

DISCUSSION

Managed care may have negatively affected patients' perceptions of overall quality of care and doctor-patient interaction. Including additional and supplementary services to the delivery of care may improve satisfaction rates.

Reimbursement systems influence prosthodontic treatment of adult patients

OBJECTIVE

To evaluate the influence of reimbursement system and organizational structure on oral rehabilitation of adult patients with tooth loss.

MATERIALS AND METHODS

Patient data were retrieved from the databases of the Swedish Social Insurance Agency. The data consisted of treatment records of patients aged 19 years and above claiming reimbursement for dental care from July 1, 2007 until June 30, 2009. Before July 1, 2008, a proportionately higher level of subsidy was available for dental care in patients 65 years and above, but thereafter the system was changed, so that the subsidy was the same, regardless of the patient's age. Prosthodontic treatment in patients 65 years and above was compared with that in younger patients before and after the change of the reimbursement system. Prosthodontic treatment carried out in the Public Dental Health Service and the private sector was also analyzed.

RESULTS

Data were retrieved for 722,842 adult patients, covering a total of 1,339,915 reimbursed treatment items. After the change of the reimbursement system, there was a decrease in the proportion of items in patients 65 years and above in relation to those under 65. Overall, there was a minimal change in the proportion of treatment items provided by the private sector compared to the public sector following the change of the reimbursement system.

CONCLUSIONS

Irrespective of service provider, private or public, financial incentive such as the reimbursement system may influence the provision of prosthodontic treatment, in terms of volume of treatment.

Patient reports of lifestyle advice in primary care

PURPOSE

Patients' perceptions of preventive lifestyle in primary care practice were examined.

METHODS

Practice was assessed with a modified version of the Primary Care Assessment Survey (PCAS). This was mailed to random samples of patients twice, using practice mailing lists from three Ontario Family Health Networks (FHNs). Family Health Networks are physician-based group practices, with additional nurse-led telephone advisory services to provide care 24 hours a day, seven days a week. The PCAS questionnaire consisted of nine scales (ranging from 0 to 100). For preventive counselling, additional questions on diet and exercise counselling were included to determine how the physician delivered the intervention.

RESULTS

Of the 2184 survey questionnaires mailed to patients, 22% were undeliverable. The response rate was 62% at valid addresses (49% of all mailed questionnaires). Of the nine scales, scores (± standard deviation) for preventive counselling were lowest at 33 ± 25. In particular, rates of diet (37%) and exercise (24%) counselling were low in the FHNs. For most other aspects of primary care services, patients generally rated FHNs highly. The majority of patients advised about diet and exercise were given verbal advice or pamphlets.

CONCLUSIONS

In these primary health care organizations, considerable room exists for increased preventive counselling, especially about diet and exercise.

Long-term management of chronic obstructive pulmonary disease: a survey of collaboration among physicians involved in pulmonary rehabilitation in Japan

BACKGROUND

This study evaluated the implementation of pulmonary rehabilitation (PR), and the extent of the collaboration between primary care and chest physicians involved in the management of chronic obstructive pulmonary disease (COPD) in Japan.

METHODS

The survey was conducted in 2006 via post and facsimile and included all medical institutions approved by the Japan Respiratory Society.

RESULTS

In total, 176 institutions responded (response rate, 27%); a PR program was conducted at 55.1% of these institutions throughout Japan, but with regional differences. The mean duration of each session in an outpatient setting was 30 min with 2 sessions per week, and the mean length of hospitalization was 2-3 weeks. Although 33% of the hospitals adopted PR programs, on a scale from none (0) to maximum achievement (100), the accomplishment score was 48. Similarly, the mean satisfaction level score for collaboration was 44. The main problem arising with regards to chest physicians' referral to general physicians was the reluctance of patients or family members (88%). Chest physicians believed that general physicians should perform early screening of patients and manage early exacerbations, including educating patients of the need to discontinue smoking.

CONCLUSIONS

Most chest physicians in Japan were not satisfied with the status of long-term COPD management. PR for COPD patients and collaboration between primary care physicians and specialists remain problematic in Japan. Moreover, there are widespread regional differences in terms of implementation. Sharing and implementing appropriate clinical information with primary care physicians according to current clinical guidelines should be emphasized.

The impact of primary care: a focused review

Primary care serves as the cornerstone in a strong healthcare system. However, it has long been overlooked in the United States (USA), and an imbalance between specialty and primary care exists. The objective of this focused review paper is to identify research evidence on the value of primary care both in the USA and internationally, focusing on the importance of effective primary care services in delivering quality healthcare, improving health outcomes, and reducing disparities. Literature searches were performed in PubMed as well as "snowballing" based on the bibliographies of the retrieved articles. The areas reviewed included primary care definitions, primary care measurement, primary care practice, primary care and health, primary care and quality, primary care and cost, primary care and equity, primary care and health centers, and primary care and healthcare reform. In both developed and developing countries, primary care has been demonstrated to be associated with enhanced access to healthcare services, better health outcomes, and a decrease in hospitalization and use of emergency department visits. Primary care can also help counteract the negative impact of poor economic conditions on health.

An official American Thoracic Society policy statement: pay-for-performance in pulmonary, critical care, and sleep medicine

RATIONALE

Pay-for-performance is a model for health care financing that seeks to link reimbursement to quality. The American Thoracic Society and its members have a significant stake in the development of pay-for-performance programs.

OBJECTIVES

To develop an official ATS policy statement addressing the role of pay-for-performance in pulmonary, critical care and sleep medicine.

METHODS

The statement was developed by the ATS Health Policy Committee using an iterative consensus process including an expert workshop and review by ATS committees and assemblies.

MEASUREMENTS AND MAIN RESULTS

Pay-for-performance is increasingly utilized by health care purchasers including the United States government. Published studies generally show that programs result in small but measurable gains in quality, although the data are heterogeneous. Pay-for-performance may result in several negative consequences, including the potential to increase costs, worsen health outcomes, and widen health disparities, among others. Future research should be directed at developing reliable and valid performance measures, increasing the efficacy of pay-for-performance programs, minimizing negative unintended consequences, and examining issues of costs and cost-effectiveness. The ATS and its members can play a key role in the design and evaluation of these programs by advancing the science of performance measurement, regularly developing quality metrics alongside clinical practice guidelines, and working with payors to make performance improvement a routine part of clinical practice.

CONCLUSIONS

Pay-for-performance programs will expand in the coming years. Pulmonary, critical care and sleep practitioners can use these programs as an opportunity to partner with purchasers to improve health care quality.

Organizational and market influences on physician performance on patient experience measures

OBJECTIVE

To examine the extent to which medical group and market factors are related to individual primary care physician (PCP) performance on patient experience measures.

DATA SOURCES

This study employs Clinician and Group CAHPS survey data (n=105,663) from 2,099 adult PCPs belonging to 34 diverse medical groups across California. Medical group directors were interviewed to assess the magnitude and nature of financial incentives directed at individual physicians and the adoption of patient experience improvement strategies. Primary care services area (PCSA) data were used to characterize the market environment of physician practices.

STUDY DESIGN

We used multilevel models to estimate the relationship between medical group and market factors and physician performance on each Clinician and Group CAHPS measure. Models statistically controlled for respondent characteristics and accounted for the clustering of respondents within physicians, physicians within medical groups, and medical groups within PCSAs using random effects.

PRINCIPAL FINDINGS

Compared with physicians belonging to independent practice associations, physicians belonging to integrated medical groups had better performance on the communication ( p=.007) and care coordination ( p=.03) measures. Physicians belonging to medical groups with greater numbers of PCPs had better performance on all measures. The use of patient experience improvement strategies was not associated with performance. Greater emphasis on productivity and efficiency criteria in individual physician financial incentive formulae was associated with worse access to care ( p=.04). Physicians located in PCSAs with higher area-level deprivation had worse performance on the access to care ( p=.04) and care coordination ( p<.001) measures.

CONCLUSIONS

Physicians from integrated medical groups and groups with greater numbers of PCPs performed better on several patient experience measures, suggesting that organized care processes adopted by these groups may enhance patients' experiences. Physicians practicing in markets with high concentrations of vulnerable populations may be disadvantaged by constraints that affect performance. Future studies should clarify the extent to which performance deficits associated with area-level deprivation are modifiable.

The General Practice Assessment Questionnaire (GPAQ) - development and psychometric characteristics

BACKGROUND

Continual quality improvement in primary care is an international priority. In the United Kingdom, the major initiative for improving quality of care is the Quality and Outcomes Framework (QoF) of the 2004 GP contract. Although the primary focus of the QoF is on clinical care, it is acknowledged that a comprehensive assessment of quality also requires valid and reliable measurement of the patient perspective, so financial incentives are included in the contract for general practices to survey patients' views. One questionnaire specified for use in the QoF is the General Practice Assessment Questionnaire (GPAQ). This paper describes the development of the GPAQ (with post-consultation and postal versions) and presents a preliminary examination of the psychometric properties of the questionnaire.

METHODS

Description of scale development and preliminary analysis of psychometric characteristics (internal reliability, factor structure), based on a large dataset of routinely collected GPAQ surveys (n = 190,038 responses to the consultation version of GPAQ and 20,309 responses to the postal version) from practices in the United Kingdom during the 2005-6 contract year.

RESULTS

Respondents tend to report generally favourable ratings. Responses were particularly skewed on the GP communication scale, though no more so than for other questionnaires in current use in the UK for which data were available. Factor analysis identified 2 factors that clearly relate to core concepts in primary care quality ('access' and 'interpersonal care') that were common to both version of the GPAQ. The other factors related to 'enablement' in the post-consultation version and 'nursing care' in the postal version.

CONCLUSION

This preliminary evaluation indicates that the scales of the GPAQ are internally reliable and that the items demonstrate an interpretable factor structure. Issues concerning the distributions of GPAQ responses are discussed. Potential further developments of the item content for the GPAQ are also outlined.

Use of preventive care by elderly male veterans receiving care through the Veterans Health Administration, Medicare fee-for-service, and Medicare HMO plans

OBJECTIVES

We compared use of preventive care among veterans receiving care through the Veterans Health Administration (VHA), Medicare fee-for-service (FFS) plans, and Medicare health maintenance organizations (HMOs).

METHODS

Using both the Costs and Use, and Access to Care files of the Medicare Current Beneficiary Survey (2000-2003), we performed a cross-sectional analysis examining self-reported use of influenza vaccination, pneumococcal vaccination, serum cholesterol screening, and serum prostate-specific antigen measurement among male veterans 65 years or older. Veterans' care was categorized as received through VHA, Medicare FFS, Medicare HMOs, VHA and Medicare FFS, or VHA and Medicare HMOs.

RESULTS

Veterans receiving care through VHA reported 10% greater use of influenza vaccination (P<.05), 14% greater use of pneumococcal vaccination (P<.01), a nonsignificant 6% greater use of serum cholesterol screening (P=.1), and 15% greater use of prostate cancer screening (P<.01) than did veterans receiving care through Medicare HMOs. Veterans receiving care through Medicare FFS reported less use of all 4 preventive measures (P<.01) than did veterans receiving care through Medicare HMOs.

CONCLUSIONS

Receiving care through VHA was associated with greater use of preventive care.

The influence of cost containment strategies and physicians' financial arrangements on patients' trust and satisfaction

Concerns have been raised about the potential for negative effects of health plans' cost containment strategies on the patient-physician relationship. We surveyed Minnesota patients with diabetes or hypertension (N = 595) and their physicians (N = 389) to assess the associations of gatekeeping, utilization profiling, and financial arrangements with patients' trust in and satisfaction with their physician. We found that patients of physicians exposed to various cost containment strategies were generally not less trusting in or less satisfied with their physicians than other patients. These results suggest that physicians may have managed potential conflicts to avoid compromising the patient-physician relationship.

Fundamental reform of payment for adult primary care: comprehensive payment for comprehensive care

Primary care is essential to the effective and efficient functioning of health care delivery systems, yet there is an impending crisis in the field due in part to a dysfunctional payment system. We present a fundamentally new model of payment for primary care, replacing encounter-based imbursement with comprehensive payment for comprehensive care. Unlike former iterations of primary care capitation (which simply bundled inadequate fee-for-service payments), our comprehensive payment model represents new investment in adult primary care, with substantial increases in payment over current levels. The comprehensive payment is directed to practices to include support for the modern systems and teams essential to the delivery of comprehensive, coordinated care. Income to primary physicians is increased commensurate with the high level of responsibility expected. To ensure optimal allocation of resources and the rewarding of desired outcomes, the comprehensive payment is needs/risk-adjusted and performance-based. Our model establishes a new social contract with the primary care community, substantially increasing payment in return for achieving important societal health system goals, including improved accessibility, quality, safety, and efficiency. Attainment of these goals should help offset and justify the costs of the investment. Field tests of this and other new models of payment for primary care are urgently needed.

Researching medical trust in the United States

PURPOSE

This article reviews research in the U.S.A. bearing on trust in physicians and medical institutions.

DESIGN/METHODOLOGY/APPROACH

This article provides a conceptual analysis, and general review of the literature.

FINDINGS

Empirical research of medical trust is burgeoning in the U.S.A., and a fairly clear conceptual model of interpersonal physician trust has emerged. However, most studies focus on individual patients and their physicians, due to the highly individualistic attitudes that prevail in the U.S.A. Lacking are studies of more social dimensions of trust in broader medical institutions. A conceptual model of trust is presented to help draw these relevant distinctions, and to review the US literature. Also presented are the full set of trust scales, developed at Wake Forest University, which follow this conceptual model. These conceptual categories may differ, however, in other languages and cultures.

ORIGINALITY/VALUE

The considerable body of research in the USA on patients' trust in individual physicians should help inform and focus international efforts to study social trust in medical institutions.

A measure of trust in insurers

BACKGROUND

Patient-centered assessments are increasingly important. Patients repeatedly emphasize the importance of trust in health care institutions and personnel.

OBJECTIVES

(1) Develop a conceptual framework for trust in health care organizations and a comprehensive, reliable measure of trust in health insurers. (2) Examine predictors and correlates of trust in insurers.

STUDY DESIGN

A conceptual framework for trust in health organizations based on theory and empirical studies was used to develop items for a structured telephone survey, which also included measures of health and utilization, doctor-patient trust, and satisfaction with care. Principal components factor analyses identified hypothesized domains of trust in health insurers and identified items for scales. Internal consistency assessment used Cronbach's alpha. Univariate analyses used Pearson's r or Student's t-tests.

SAMPLE

Insured residents of Southeastern Michigan (n=400).

RESULTS

Respondents were diverse in age, gender, ethnicity, health, and socioeconomic status. One dominant factor (eigenvalue>10) included hypothesized domains: administrative competence, clinical competence, advocacy and beneficence, fairness, honesty and openness, and one global item. Multidimensional scales were reliable (long version 13 items, alpha=0.95, short: 9 items, alpha=0.91). Insurer trust correlated strongly with trust in doctors (r=0.49 and 0.46) and satisfaction with care (r=0.70 and 0.66), and with an item assessing overall worry about health insurance (r=-0.37 and -0.35). Those with less trust in their insurer were more likely to say that they would change insurance plans (p<.001).

CONCLUSIONS

This well-grounded, reliable measure of enrollee trust in insurers can be a useful patient-centered assessment tool.

Managed care, physician job satisfaction, and the quality of primary care

OBJECTIVE

To determine the associations between managed care, physician job satisfaction, and the quality of primary care, and to determine whether physician job satisfaction is associated with health outcomes among primary care patients with pain and depressive symptoms.

DESIGN

Prospective cohort study.

SETTING

Offices of 261 primary physicians in private practice in Seattle.

PATIENTS

We screened 17,187 patients in waiting rooms, yielding a sample of 1,514 patients with pain only, 575 patients with depressive symptoms only, and 761 patients with pain and depressive symptoms; 2,004 patients completed a 6-month follow-up survey.

MEASUREMENTS AND RESULTS

For each patient, managed care was measured by the intensity of managed care controls in the patient's primary care office, physician financial incentives, and whether the physician read or used back pain and depression guidelines. Physician job satisfaction at baseline was measured through a 6-item scale. Quality of primary care at follow-up was measured by patient rating of care provided by the primary physician, patient trust and confidence in primary physician, quality-of-care index, and continuity of primary physician. Outcomes were pain interference and bothersomeness, Symptom Checklist for Depression, and restricted activity days. Pain and depression patients of physicians with greater job satisfaction had greater trust and confidence in their primary physicians. Pain patients of more satisfied physicians also were less likely to change physicians in the follow-up period. Depression patients of more satisfied physicians had higher ratings of the care provided by their physicians. These associations remained after controlling statistically for managed care. Physician job satisfaction was not associated with health outcomes.

CONCLUSIONS

For primary care patients with pain or depressive symptoms, primary physician job satisfaction is associated with some measures of patient-rated quality of care but not health outcomes.

Vulnerability and unmet health care needs. The influence of multiple risk factors

CONTEXT

Previous studies have demonstrated a strong association between minority race, low socioeconomic status (SES), and lack of potential access to care (e.g., no insurance coverage and no regular source of care) and poor receipt of health care services. Most studies have examined the independent effects of these risk factors for poor access, but more practical models are needed to account for the clustering of multiple risks.

OBJECTIVE

To present a profile of risk factors for poor access based on income, insurance coverage, and having a regular source of care, and examine the association of the profiles with unmet health care needs due to cost. Relationships are examined by race/ethnicity.

DESIGN

Analysis of 32,374 adults from the 2000 National Health Interview Survey.

MAIN OUTCOME MEASURES

Reported unmet needs due to cost: missing/delaying needed medical care, and delaying obtaining prescriptions, mental health care, or dental care.

RESULTS

Controlling for personal demographic and community factors, individuals who were low income, uninsured, and had no regular source of care were more likely to miss or delay needed health care services due to cost. After controlling for these risk factors, whites were more likely than other racial/ethnic groups to report unmet needs. When presented as a risk profile, a clear gradient existed in the likelihood of having an unmet need according to the number of risk factors, regardless of racial/ethnic group.

CONCLUSION

Unmet health care needs due to cost increased with higher risk profiles for each racial and ethnic group. Without attention to these co-occurring risk factors for poor access, it is unlikely that substantial reductions in disparities will be made in assuring access to needed health care services among vulnerable populations.

Physicians and prepaid group practices

Prepaid group practices (PGPs) are complex organizations that directly combine prepayment for health care with a comprehensive health care delivery system. PGPs' ability to manage their physician staffing efficiently must be placed in context with the cost and quality of their care. It seems unlikely that PGPs or their use of staff will proliferate. With increased integration of care through disease management programs and use of clinical information technology, it should be possible for the United States as a whole to come closer to achieving the care delivery goals that PGPs have set in the past.

Does Capitation Matter? Impacts on Access, Use, and Quality

Provider capitation may constrain costs, but it also may reduce access and quality of care. We examine the impacts of capitating the usual source of care of enrollees in health maintenance organizations (HMOs). We account for the endogeneity of capitation and other characteristics using generalized methods of moments (GMM) estimation on a sample from the Medical Expenditure Panel Survey for 1996 and 1997. Being organized as a group/staff HMO generally has stronger impact on access and quality than capitation. Capitation by itself may increase access to consumers' usual sources of care, improve primary preventive care, and reduce coordination, but estimates with GMM were not statistically significant.

Managed care organization and the quality of diabetes care: the Translating Research Into Action for Diabetes (TRIAD) study

OBJECTIVE

To examine the association between the organizational model and diabetes processes of care.

RESEARCH DESIGN AND METHODS

We used data from the Translating Research into Action for Diabetes (TRIAD), a multicenter study of diabetes care in managed care, including 8354 patients with diabetes. We identified five model types: for-profit group/network, for-profit independent practice association (IPA), nonprofit group/network, nonprofit IPA, and nonprofit group/staff. Process measures included retinal, renal, foot, lipid, and HbA(1c) testing; aspirin recommendations; influenza vaccination; and a sum of these seven processes of care over 1 year. Hierarchical regression models were constructed for each process measure and accounted for clustering at the health plan and provider group levels and adjusted for participant age, sex, race, ethnicity, diabetes treatment and duration, education, income, health status, and survey language.

RESULTS

Participant membership in the model types ranged from 9% in nonprofit IPA models to 38% in nonprofit group/staff models. Over 75% of participants received most of the processes of care, regardless of model type. However, among for-profit plans, group/network models provided on average more processes of care than IPA models (5.5 vs. 4.7, P < 0.0001), and group/network models generally increased the probability of receiving a process by >or=10 percentage points. Among nonprofit plans, no effect of model type was found.

CONCLUSIONS

Among for-profit plans, group/network models provided better diabetes processes of care than IPA models. Although reasons are speculative, this may be due to the clinical infrastructure available in group models that is not available in IPA models.

Development and testing of the health care system distrust scale

BACKGROUND

Distrust of the health care system may be a significant barrier to seeking medical care, adhering to preventive health care and treatment regimens, and participating in medical research.

OBJECTIVE

To describe the development and psychometric testing of an instrument (the Health Care System Distrust Scale) to measure distrust of the health care system.

METHODS

Scale development involved 2 phases. In Phase 1, a pilot instrument was developed based on a conceptual model of health care-related distrust. Draft items were created using focus group sessions with members of the general public, literature review, and expert opinion. Draft items were pilot tested with 55 individuals waiting to be assigned to jury duty at the Municipal Court of Philadelphia. A priori, candidate items for elimination or revision included those with >5% missing data, extremely low or high interitem or item-total correlations, or those having a negative effect on the scale's internal consistency. In Phase 2, we conducted a survey of 400 prospective jurors to assess the reliability and validity of the final scale scores.

RESULTS

In Phase 1, a 10-item scale was constructed that included 4 items measuring honesty, 2 items measuring confidentiality, 2 items measuring competence, and 2 items measuring fidelity. The participants in Phase 2 had a mean age of 41 years. Forty-three percent were African-American, 45% white, and 4% Hispanic. Scores on the Health Care System Distrust scale ranged from 12 to 46 with a possible range from 10 to 50. The mean score was 29.4 with a standard deviation of 6.33. No item had over 5% missing data. Internal consistency (Cronbach's alpha) was 0.75. Item-total correlations ranged from 0.27 to 0.57. Principal components analysis revealed 1 general component accounting for 32% of the variance. Nine of the variables had loadings higher than 0.40. As predicted, distrust of the health care system was higher among African Americans than whites and was inversely correlated with trust in personal physicians.

CONCLUSIONS

Initial testing suggests that we developed an instrument with valid and reliable scores in order to measure distrust of the health care system. Future research is needed to evaluate the validity and reliability of the Health Care System Distrust scale among diverse populations. This instrument can facilitate the investigation of the prevalence, causes, and effects of health care system distrust in the United States.

Race and trust in the health care system

OBJECTIVE

A legacy of racial discrimination in medical research and the health care system has been linked to a low level of trust in medical research and medical care among African Americans. While racial differences in trust in physicians have been demonstrated, little is known about racial variation in trust of health insurance plans and hospitals. For the present study, the authors analyzed responses to a cross-sectional telephone survey to assess the independent relationship of self-reported race (non-Hispanic black or non-Hispanic white) with trust in physicians, hospitals, and health insurance plans.

METHODS

Respondents ages 18-75 years were asked to rate their level of trust in physicians, health insurance plans, and hospitals. Items from the Medical Mistrust Index were used to assess fear and suspicion of hospitals.

RESULTS

Responses were analyzed for 49 (42%) non-Hispanic black and 69 (58%) non-Hispanic white respondents (N=118; 94% of total survey population). A majority of respondents trusted physicians (71%) and hospitals (70%), but fewer trusted their health insurance plans (28%). After adjustment for potential confounders, non-Hispanic black respondents were less likely to trust their physicians than non-Hispanic white respondents (adjusted absolute difference 37%; p=0.01) and more likely to trust their health insurance plans (adjusted absolute difference 28%; p=0.04). The difference in trust of hospitals (adjusted absolute difference 13%) was not statistically significant. Non-Hispanic black respondents were more likely than non-Hispanic white respondents to be concerned about personal privacy and the potential for harmful experimentation in hospitals.

CONCLUSIONS

Patterns of trust in components of our health care system differ by race. Differences in trust may reflect divergent cultural experiences of blacks and whites as well as differences in expectations for care. Improved understanding of these factors is needed if efforts to enhance patient access to and satisfaction with care are to be effective.

Which enrollees bypass their gatekeepers in a point-of-service plan?

BACKGROUND AND OBJECTIVES

Like Health Maintenance Organizations, point-of-service (POS) health plans use primary care gatekeepers, and they permit self-referral to specialists at increased costs to the enrollee. The main objective of this study was to contrast patients who self-referred with those referred by their primary care physician.

RESEARCH DESIGN

We conducted a cross-sectional telephone survey of 606 recent users of specialists in a large Midwestern POS health plan; response rate was 65%. We compared 148 enrollees who self-referred with 458 who had a physician referral.

RESULTS

Self-referral was most common among those with a long-term relationship with a specialist (odds ratio [OR] = 2.08) and those dissatisfied with their primary care physician (OR = 3.65), and was rare among those with a long-standing relationship with a primary care physician (OR = 0.46). Most self-referred enrollees (68%) thought paying the additional cost for self-referral was worthwhile, and they were more dissatisfied with the quality and variety of the plan's specialist network.

CONCLUSIONS

Continuity with a single physician influences how patients access specialty care. Expanding the panel of specialists in-network and encouraging long-term relationships with primary care physicians are likely to limit self-referral in a POS plan.

Racial and ethnic disparities in the primary care experiences of children: a review of the literature

Substantial racial and ethnic disparities persist in children's health and use of health services in the United States. Although equitable access to primary care services is widely promoted as one of the most feasible remedies to reduce health disparities, there has only recently been an effort to assess its quality, particularly for children. Racial and socioeconomic differences in access to care have been previously well documented, but recent research has begun to elucidate differences in more qualitative experiences in the receipt of primary care. This article presents a synthesis and critique of the existing research according to the core attributes of primary care: first-contact care, longitudinality, comprehensiveness, and coordination. Finally, the article proposes an agenda for further research into the pathways by which racial and ethnic disparities in primary care exist.

The effect of capitation on switching primary care physicians

OBJECTIVE

To examine the relationship between patient case-mix, utilization, primary care physician (PCP) payment method, and the probability that patients switch their PCPs.

DATA SOURCES/STUDY SETTING

Administrative enrollment and claims/encounter data for 1994-1995 from four physician organizations.

STUDY DESIGN

We developed a conceptual model of patient switching behavior, which we used to guide the specification of multivariate logistic analyses focusing on interactions between patient case-mix, utilization, and PCP reimbursement methods.

DATA COLLECTION/EXTRACTION METHODS

Claims data were aggregated to the encounter level; a switch was defined as a change in PCP since the previous encounter. The PCPs were reimbursed on either a capitated or fee-for-service (FFS) basis.

PRINCIPAL FINDINGS

Patients with stable chronic conditions (Ambulatory Diagnostic Groups [ADG] 10) and capitated PCPs were 36 percent more likely to switch PCPs than similar patients with FFS PCPs, controlling for patient age and sex and physician fixed effects. When the number of previous encounters was included in the model this relationship was no longer significant. Instead high utilizers with capitated PCPs were significantly more likely to switch PCPs than were similar patients with FFS PCPs.

CONCLUSIONS

A patient's demographics and utilization are associated with the probability that the patient will switch PCPs. Capitated PCP payment was associated with higher rates of switching among high utilizers of health care resources. These findings raise concerns about the continuity and quality of care experienced by vulnerable patients in an era of changing financial incentives.

Race and trust in the health care system

OBJECTIVE

A legacy of racial discrimination in medical research and the health care system has been linked to a low level of trust in medical research and medical care among African Americans. While racial differences in trust in physicians have been demonstrated, little is known about racial variation in trust of health insurance plans and hospitals. For the present study, the authors analyzed responses to a cross-sectional telephone survey to assess the independent relationship of self-reported race (non-Hispanic black or non-Hispanic white) with trust in physicians, hospitals, and health insurance plans.

METHODS

Respondents ages 18-75 years were asked to rate their level of trust in physicians, health insurance plans, and hospitals. Items from the Medical Mistrust Index were used to assess fear and suspicion of hospitals.

RESULTS

Responses were analyzed for 49 (42%) non-Hispanic black and 69 (58%) non-Hispanic white respondents (N=118; 94% of total survey population). A majority of respondents trusted physicians (71%) and hospitals (70%), but fewer trusted their health insurance plans (28%). After adjustment for potential confounders, non-Hispanic black respondents were less likely to trust their physicians than non-Hispanic white respondents (adjusted absolute difference 37%; p=0.01) and more likely to trust their health insurance plans (adjusted absolute difference 28%; p=0.04). The difference in trust of hospitals (adjusted absolute difference 13%) was not statistically significant. Non-Hispanic black respondents were more likely than non-Hispanic white respondents to be concerned about personal privacy and the potential for harmful experimentation in hospitals.

CONCLUSIONS

Patterns of trust in components of our health care system differ by race. Differences in trust may reflect divergent cultural experiences of blacks and whites as well as differences in expectations for care. Improved understanding of these factors is needed if efforts to enhance patient access to and satisfaction with care are to be effective.

From physician to consumer: the effectiveness of strategies to manage health care utilization

Many strategies are commonly used to influence physician behavior in managed care organizations. This review examines the effectiveness of three mechanisms to influence physician behavior: financial incentives directed at providers or patients, policies/procedures for managing care, and the selection/education of both providers and patients. The authors reach three conclusions. First, all health care systems use financial incentives, but these mechanisms are shifting away from financial incentives directed at the physician to those directed at the consumer. Second, heavily procedural strategies such as utilization review and gatekeeping show some evidence of effectiveness but are highly unpopular due to their restrictions on physician and patient choice. Third, a future system built on consumer choice is contradicted by mechanisms that rely solely on narrow networks of providers or the education of physicians. If patients become the new locus of decision making in health care, provider-focused mechanisms to influence physician behavior will not disappear but are likely to decline in importance.

Insurance product design and its effects: trade-offs along the managed care continuum

This paper uses 1996-97 Community Tracking Study data to analyze the effects of different insurance product designs on service use, access, and consumer assessments of care for nonelderly people with employer-sponsored insurance. Product types are defined by features including use of networks, gatekeeping, capitation, and group/staff model delivery systems. We found no evidence of differences across product types in unmet need or delayed care or use of hospitals, surgery, or emergency rooms. At the same time, different product designs present purchasers with a clear trade-off between paying more out of pocket and encountering more administrative barriers to care. In addition, an increasing proportion of consumers report dissatisfaction with choice of physicians and low trust in physicians as one moves along the managed care continuum from unmanaged to heavily managed products. Our findings have implications for efforts to regulate managed care. The existence of a trade-off between out-of-pocket costs and administrative barriers to care means that some forms of regulation run the risk of reducing choices available to consumers. This is particularly true of regulations that would change the nature of managed care products by prohibiting the use of specific care management tools. To the extent that the backlash against managed care targets restrictions on choice and administrative hassles among consumers who nonetheless choose more heavily managed products because of their lower cost, eliminating heavily managed products would leave those consumers worse off.

Plan characteristics and SSI enrollees' access to and quality of care in four TennCare MCOs

OBJECTIVE

To assess hypotheses about which managed care organization (MCO) characteristics affect access to care and quality of care--including access to specialists, providers' knowledge about disability, and coordination of care--for people with disabilities.

DATA SOURCES/STUDY SETTING

Survey of blind/disabled Supplemental Security Income (SSI) enrollees in four MCOs serving TennCare, Tennessee's Medicaid managed care program, in Memphis, conducted from 1998 through spring 1999.

STUDY DESIGN

We compared enrollee reports of access and quality across the four MCOs using regression methods, and we use case study methods to assess whether patterns both within and across MCOs are consistent with the hypotheses.

DATA COLLECTION

We conducted computer-assisted telephone surveys and used regression analysis to compare access and quality controlling for enrollee characteristics.

PRINCIPAL FINDINGS

Although the four MCOs' characteristics varied, access to providers, coordination of care, and access to some services were generally similar across MCOs. Enrollees in one plan, the only MCO with a larger provider network and that paid physicians on a fee-for-service basis, reported their providers were more knowledgeable, and they had more secondary preventive care visits. Differences found in access to specialists and delays in approving care appear to be unrelated to characteristics reported by the MCOs, but instead may be related to how tightly utilization is reviewed.

CONCLUSIONS

Plan networks, financial incentives, utilization management methods, and state requirements are important areas for further study, and, in the meantime, ongoing monitoring of SSI enrollees in each MCO may be important for detecting problems and successes.

HMO plan performance update: an analysis of the literature, 1997-2001

This paper synthesizes results from peer-reviewed literature published from 1997 to mid-2001, on various dimensions of health maintenance organization (HMO) plan performance. Results from seventy-nine studies suggest that both types of plans provide roughly comparable quality of care, while HMOs lower use of hospital and other expensive resources somewhat. At the same time, HMO enrollees report worse results on many measures of access to care and lower levels of satisfaction, compared with non-HMO enrollees. Quality-of-care results in particular are heterogeneous, which suggests that quality is not uniform--that it varies widely among providers, plans (HMO and non-HMO), and geographic areas.

Managed care, primary care, and the patient-practitioner relationship

OBJECTIVES

This study examines how specific attributes of managed health plans influence patients' relationships with their primary care practitioners (PCPs) and determines whether these effects are mediated by access to, continuity with, or perceived choice of PCPs.

DESIGN, SETTING, PATIENTS

The data source was the nationally representative 1996/97 Community Tracking Study Household Survey (cumulative response rate 65%). The study population (N = 19,415) was composed of 18- to 64-year-old adults whose most recent visit in the past 12 months was made to their primary care delivery site.

MAIN OUTCOME MEASURE

Patients' ratings of their interpersonal relationships with their PCPs as measured by a 7-item scale.

RESULTS

Gatekeeping arrangements that require patients to select a primary care physician or obtain authorization for specialty referrals were associated with lower ratings of the patient-PCP relationship. Health plan use of a provider network had no effect on the patient-PCP scale score. Although there were no significant differences across any insurance payer categories, uninsured adults rated their relationships with PCPs as significantly poorer than did their insured counterparts. Shorter office waits, having a specific clinician at the primary care site, better perceived choice of PCPs, and a longer duration of relationship with the primary care practitioner were associated with higher ratings of the patient-PCP relationship. Perceived choice of primary care practitioners, but not access to or continuity with PCPs, attenuated some of the negative effects of gatekeeping arrangements on patients' relationships with their primary care practitioners.

CONCLUSIONS

Managed health plans that loosen restrictions on provider choice, relax gatekeeping arrangements, or promote access to and continuity with PCPs, are likely to experience higher patient satisfaction with their primary care practitioner relationships. Lack of health insurance impedes the development of patients' relationships with their primary care practitioners.

Is health plan employer data and information set performance associated with withdrawal from medicare managed care?

BACKGROUND

Withdrawals of health plans from Medicare have affected more than 1.6 million beneficiaries. Some plans claim that providing higher quality care raises costs, lowers profits, and spurs withdrawal because plans cannot sustain high quality care under current payment levels.

OBJECTIVE

To assess whether higher performance by Medicare health plans on quality indicators was associated with withdrawal.

DESIGN

Retrospective cohort study.

SUBJECTS

Taking each county where a contract was active as a unit of analysis, Medicare managed care plans active in 2310 contract-county combinations in 1997 were studied and followed for 3 years.

MEASURES

Independent variables were scores on six indicators from the Health Plan Employer Data and Information Set (HEDIS) for each contract, collapsed into two summary measures: clinical and ambulatory care access. Separate Cox proportional hazards regressions were used for each indicator, and each summary measure, to assess the association of HEDIS performance with our outcome measure, time-to-withdrawal from Medicare. Multiple potential confounders were adjusted for.

RESULTS

Of 2310 managed care contract-county combinations, 877 (38%) withdrew. The proportion of contract-counties with high scores on the summary clinical quality measure that withdrew was one-fifth that for low scorers (4.2% vs. 20.5%). For summary ambulatory care access performance, the corresponding ratio was two-fifths (12.8% vs. 32.0%). Lower payments were associated with higher withdrawal risk, but also higher clinical and ambulatory care access quality performance. In separate multivariable analyses controlling for confounders, both high clinical performance (HR, 0.18; 95% CI, 0.08-0.42) and high ambulatory care access performance (HR, 0.53; 95% CI, 0.27-1.07) were independently associated with lower withdrawal risk.

CONCLUSIONS

Health plans continuing to provide care to Medicare beneficiaries have higher average performance on HEDIS clinical and ambulatory care access measures than plans that withdrew.

Measuring access to effective care among elderly medicare enrollees in managed and Fee-for-Service care: a retrospective cohort study

BACKGROUND

Our aim was to compare access to effective care among elderly Medicare patients in a Staff Model and Group Model HMO and in Fee-for-Service (FFS) care.

METHODS

We used a retrospective cohort study design, using claims and automated medical record data to compare achievement on quality indicators for elderly Medicare recipients. Secondary data were collected from 1) HMO data sets and 2) Medicare claims files for the time period 1994-95. All subjects were Medicare enrollees in a defined area of New England: those enrolled in two divisions of a managed care plan with different physician payment arrangements: a staff model, and a group model; and the Medicare FFS population. We abstracted information on indicators covering several domains: preventive, diagnosis-specific, and chronic disease care.

RESULTS

On the indicators we created and tested, access in the single managed care plan under study was comparable to or better than FFS care in the same geographic region. Percent of Medicare recipients with breast cancer screening was 36 percentage points higher in the staff model versus FFS (95% confidence interval 34-38 percentage points). Follow up after hospitalization for myocardial infarction was 20 percentage points higher in the group model than in FFS (95% confidence interval 14-26 percentage points).

CONCLUSION

According to indicators developed for use in both claims and automated medical record data, access to care for elderly Medicare beneficiaries in one large managed care organization was as good as or better than that in FFS care in the same geographic area.

Self-referral in point-of-service health plans

CONTEXT

Most health maintenance organizations offer products with loosened restrictions on patients' access to specialty care. One such product is the point-of-service (POS) plan, which combines "gatekeeping" arrangements with the ability to self-refer at increased out-of-pocket costs. Few data are available from formal evaluations of this new type of plan.

OBJECTIVES

To comprehensively describe the self-referral process in POS plans by quantifying rates of self-referral, identifying patients most likely to self-refer, characterizing patients' reasons for self-referral, and assessing satisfaction with specialty care.

DESIGN

Retrospective cohort analysis using administrative databases composed of members aged 0 to 64 years who were enrolled in 3 POS health plans in the Midwest (n = 265 843), Northeast (n = 80 292), and mid-Atlantic (n = 39 888) regions for 6 to 12 months in 1996, and a 1997 telephone survey of specialty care users (n = 606) in the midwestern plan.

MAIN OUTCOME MEASURES

Self-referred service use and charges, reasons for self-referral, and satisfaction with specialty care.

RESULTS

Overall, 8.8% of enrollees in the midwestern POS plan, 16.7% in the northeastern plan, and 17.3% in the mid-Atlantic plan self-referred for at least 1 physician or nonphysician clinician visit. The proportions of enrollees self-referring to generalists (4.7%-8.5%) were slightly higher than the proportions self-referring to specialists (3.7%-7.2%) across all 3 plans. Nine percent to 16% of total charges were due to self-referral. The chances of self-referral to a specialist were increased for patients with chronic and orthopedic conditions, higher cost sharing for physician-approved services, and less continuity with their regular physician. Patients who self-referred to specialists preferred to access specialty care directly (38%), reported relationship problems with their regular physicians (28%), had an ongoing relationship with a specialist (23%), were confused about insurance rules (8%), and did not have a regular physician (3%). Compared with those referred to specialists by a physician, patients who self-referred were more satisfied with the specialty care they received.

CONCLUSIONS

Having the option to self-refer is enough for most POS plan enrollees; 93% to 96% of enrollees did not exercise their POS option to obtain specialty care via self-referral during a 1-year interval. The potential downside of uncoordinated, self-referred service use in POS health plans is limited and counterbalanced by higher patient satisfaction with specialist services.
