How did welfare reform affect the health insurance coverage of women and children?

OBJECTIVE: To measure the change in U.S. women and children's health insurance coverage as a result of welfare reform (i.e. the creation of Temporary Assistance for Needy Families or TANF) in 1996. DATA SOURCE: 1992-1999 longitudinal data from the Survey of Income and Program Participation (SIPP) merged with data on the timing of state implementation of welfare reform after 1996. Two key advantages of the SIPP data are that they permit matching type of insurance coverage to the welfare policy environment in each state in each month, and permit controlling for individual-level fixed effects. STUDY DESIGN: We measure how much insurance coverage changed after welfare reform using a difference in differences method that eliminates the influence of time-invariant unobserved individual heterogeneity and of statewide trends in insurance coverage. Models also control for individual, state, and year fixed effects, individual-level characteristics such as education, age, and number of children, plus state-level variables such as real per capita income, real minimum wage, and Medicaid eligibility. DATA COLLECTION/EXTRACTION METHODS: We limit our analysis to the SIPP data specific to the month just completed prior to the interview; as a result, we have up to twelve observations for each individual in the SIPP. This paper uses pooled data from the 1992-1996 panels of the SIPP covering the period 1992-1999. Publicly available state identifiers permit the merger of state policies and macroeconomic variables with the SIPP. PRINCIPAL FINDINGS: TANF implementation is associated with an 8.1 percent increase in the probability that a welfare-eligible woman was uninsured. Welfare reform had less of an impact on the health insurance coverage of children. For example, TANF implementation was associated with a 3.0 percent increase in the probability that a welfare-eligible child lacked health insurance. CONCLUSIONS: An unintended consequence of welfare reform was to adversely impact the health insurance coverage of economically vulnerable women and children, and that this impact was several times larger than the previous literature implies.

Changes in the use of postacute care during the initial Medicare payment reforms.

OBJECTIVE: To examine changes in postacute care (PAC) use during the initial Medicare payment reforms enacted by the Balanced Budget Act of 1997. DATA SOURCES: We used claims data from the 5 percent Medicare beneficiary sample in 1996, 1998, and 2000. Linked data from the Denominator file, Provider of Service file, and Area Resource File provided additional patient, hospital, and market-area characteristics. STUDY DESIGN: Six disease groups with high PAC use were selected for analysis. We used multinomial logit regression to examine how PAC use differed by year of service, controlling for patient, hospital, and market-area characteristics. PRINCIPAL FINDINGS: There were major changes in PAC use, and a portion of services shifted to settings where reimbursement remained cost-based. During the first reform, the home health agency interim payment system, home health use decreased consistently across disease groups. This decrease was accompanied by increased use in skilled nursing facilities (SNFs). Following the implementation of the prospective payment system for SNFs, the use of inpatient rehabilitation facilities increased. CONCLUSIONS: The shift in usage among settings occurred in two stages that corresponded to the timing of payment reforms for home health agencies and SNFs. Evidence strongly suggests the substitutability between PAC settings. Financial incentives, in addition to clinical needs and individual preferences, play a major role in PAC use.

Provider attitudes toward pay-for-performance programs: development and validation of a measurement instrument.

OBJECTIVE: To develop an instrument for assessing physician attitudes toward quality incentive programs, and to assess its reliability and validity. DATA SOURCES: Study involved primary data collection. A 40-item paper and pencil survey of primary care physicians in Rochester, New York, and Massachusetts was conducted between May 2004 and December 2004. Seven-hundred and ninety-eight completed questionnaires were received, representing a response rate of 32 percent (798/2,497). STUDY DESIGN: Based on an extensive review of the literature and discussions with experts in the field, we developed a conceptual framework representing the features of pay-for-performance (P4P) programs hypothesized to affect physician behavior in that context. A draft questionnaire was developed based on that conceptual model and pilot tested in three groups of physicians. The questionnaire was modified based on the physician feedback, and the revised version was distributed to 2,497 primary care physicians affiliated with two of the seven sites participating in Rewarding Results, a national evaluation of quality target and financial incentive programs. DATA COLLECTION: Respondents were randomly divided into a derivation and a validation sample. Exploratory factor analysis was applied to the responses of the derivation sample. Those results were used to create scales in the validation sample, and these were then subjected to multitrait analysis (MTA). One scale representing physicians' perception of the impact of P4P on their clinical practice was regressed on the other scales as a test of construct validity. PRINCIPAL FINDINGS: Seven constructs were identified and demonstrated substantial convergent and discriminant validity in the MTA: awareness and understanding, clinical relevance, cooperation, unintended consequences, control, financial salience, and impact. Internal consistency reliabilities (Cronbach's alpha coefficients) ranged from 0.50 to 0.80. A statistically significant 25 percent of the variation in perceived impact was accounted for by physician perceptions of the other six characteristics of P4P programs. CONCLUSIONS: It is possible to identify and measure the key salient features of P4P programs using a valid and reliable 26-item survey. This instrument may now be used in further studies to better understand the impact of P4P programs on physician behavior.

Racial variation in end-of-life intensive care use: a race or hospital effect?

OBJECTIVE: To determine if racial and ethnic variations exist in intensive care (ICU) use during terminal hospitalizations, and, if variations do exist, to determine whether they can be explained by systematic differences in hospital utilization by race/ethnicity. DATA SOURCE: 1999 hospital discharge data from all nonfederal hospitals in Florida, Massachusetts, New Jersey, New York, and Virginia. DESIGN: We identified all terminal admissions (N = 192,705) among adults. We calculated crude rates of ICU use among non-Hispanic whites, blacks, Hispanics, and those with "other" race/ethnicity. We performed multivariable logistic regression on ICU use, with and without adjustment for clustering of patients within hospitals, to calculate adjusted differences in ICU use and by race/ethnicity. We explored both a random-effects (RE) and fixed-effect (FE) specification to adjust for hospital-level clustering. DATA COLLECTION: The data were collected by each state. PRINCIPAL FINDINGS: ICU use during the terminal hospitalization was highest among nonwhites, varying from 64.4 percent among Hispanics to 57.5 percent among whites. Compared to white women, the risk-adjusted odds of ICU use was higher for white men and for nonwhites of both sexes (odds ratios [ORs] and 95 percent confidence intervals: white men = 1.16 (1.14-1.19), black men = 1.35 (1.17-1.56), Hispanic men = 1.52 (1.27-1.82), black women = 1.31 (1.25-1.37), Hispanic women =1.53 (1.43-1.63)). Additional adjustment for within-hospital clustering of patients using the RE model did not change the estimate for white men, but markedly attenuated observed differences for blacks (OR for men =1.12 (0.96-1.31), women = 1.10 (1.03-1.17)) and Hispanics (OR for men =1.19 (1.00-1.42), women = 1.18 (1.09-1.27)). Results from the FE model were similar to the RE model (OR for black men = 1.10 (0.95-1.28), black women = 1.07 (1.02-1.13) Hispanic men = 1.17 (0.96-1.42), and Hispanic women = 1.14 (1.06-1.24)) CONCLUSIONS: The majority of observed differences in terminal ICU use among blacks and Hispanics were attributable to their use of hospitals with higher ICU use rather than to racial differences in ICU use within the same hospital.

Quality improvement and changes in diabetic patient outcomes in an academic nurse practitioner primary care practice.

PURPOSE: To examine a set of system interventions in the management of patients with diabetes and the outcomes of their care. DATA SOURCES: Preintervention and postintervention data collected from electronic medical records. CONCLUSIONS: The sample size was smaller than expected, contributing to a lack of statistical significance from preintervention to postintervention in the patient outcome measures. The systems-level variables that were under the direct control of the clinic staff (e.g., pneumococcal vaccine given) showed great improvement. In the preintervention period, the percentage of "yes" responses to the system-level variables ranged from 8 to 24 and jumped to 16 to 95 after the intervention. IMPLICATIONS FOR PRACTICE: Unequivocally, this project demonstrated that systems-level changes result in improved care being provided to patients; however, these had minimal impact on the patient outcome variables. Promoting change in patient behavior is difficult, which may have contributed to the lack of significance in this area, while the variables under the direct control of the clinic staff were more easily changed.

The use of the nicotine inhaler in smoking cessation.

PURPOSE: To raise awareness among nurse practitioners (NPs) about the nicotine inhaler by providing clinical and practical information about the use of the nicotine inhaler as a treatment option for smoking cessation. DATA SOURCES: This included data-based and review articles in the medical literature, tobacco use and dependence clinical practice guideline, and Medline and Cinahl search engines. Criteria for search keywords were "nicotine inhaler" and "nicotine replacement therapy." Initial search was done in December 2004. CONCLUSIONS: The nicotine inhaler has been tested as safe and efficacious in the treatment of tobacco cessation. Clinical trials show the nicotine inhaler to be useful alone or as an adjunct to other pharmacological therapies. Current national guidelines recommend that the nicotine inhaler be used in smoking cessation therapy. IMPLICATIONS FOR PRACTICE: The nicotine inhaler is appropriate for many different smokers, including certain types of cardiac patients. NPs can include the nicotine inhaler in a group of nicotine replacement therapies to ensure that smokers are successful in tobacco cessation.

Health promotion for women with human immunodeficiency virus or acquired immunodeficiency syndrome.

PURPOSE: The purpose of this pilot study was twofold: first, to modify Stuifbergen's health promotion intervention initially developed for women with multiple sclerosis for use among women with human immunodeficiency virus or acquired immunodeficiency syndrome (HIV/AIDS) and to evaluate the feasibility of the newly modified health promotion intervention named "Put Health Into Living" (PHIL). The pilot study was completed in two phases. DATA SOURCES: In phase I, data were derived from a literature review, a focus group of women with HIV/AIDS (n= 7), a panel of experts who reviewed the intervention for content, and three female community workers who evaluated the intervention for the context of living with HIV/AIDS, cultural relevancy, and literacy. During phase II, a pretest/posttest one-group design was used to determine the feasibility of the study methods, content, and format of the health promotion intervention among 10 women with HIV/AIDS. CONCLUSIONS: The pilot study demonstrated the importance of a health promotion intervention for a vulnerable population. Participants verbalized the benefits of attending a health promotion program to gain knowledge and skills to promote their health. One woman said, "I have been positive for 20 years now and no one has talked to me just about my overall health." Participants indicated the PHIL intervention offered a supportive group environment, an overall health focus, and an acceptable format. IMPLICATIONS FOR PRACTICE: Health promotion is a desirable goal for persons living with a chronic disease, and the PHIL intervention has the potential to benefit persons living with HIV/AIDS if subsequent evidence is found in further testing of the intervention.

Reducing cardiovascular disease risk in patients with diabetes: a message from the National Diabetes Education Program.

PURPOSE: To provide nurse practitioners (NPs) a review of current practice guidelines that help clinicians' efforts to reduce the morbidity and mortality associated with diabetes and its major macrovascular complications. DATA SOURCES: This paper presents data from major evidence-based studies and clinical trials that define the scope of the problem, the rationale for risk reduction, and a patient-centered action plan for NPs to effectively manage cardiovascular risk factors in people with diabetes. CONCLUSIONS: NPs are active partners with the National Diabetes Education Program and play a key role in efforts to effectively manage cardiovascular risk factors in people with diabetes and improve their awareness of the link between diabetes and heart disease and stroke. IMPLICATIONS FOR PRACTICE: The action plan to reduce cardiovascular risk in people with diabetes will help NPs to implement the most effective management strategies for medical nutrition therapy, physical activity, and pharmacological therapy required for patient-centered proactive management of hyperglycemia, hypertension, and lipid abnormalities.

Adequate access to posthospital home health services: differences between urban and rural areas.

The health care environment in rural areas changed dramatically in the 1980s. Policy-makers are concerned that these changes have reduced access to care among residents of rural areas. This study measures adequate access to Medicare home health services and determines whether it differs for urban and rural beneficiaries. Adequate access to care is measured by whether a patient with a specific health condition received a level of skilled services predetermined as appropriate for that condition. The predetermined levels of care were developed in an earlier study and were found to correlate with adverse outcomes. This study focused on patients with diabetes mellitus and surgical hip procedures to concentrate on access to skilled nursing services and physical therapy services. To conduct the analysis, a data base was constructed that included both patient utilization and health status data, drawing on three different data sources: Medicare hospital claims data, Medicare home health bill record data, and home health plan of treatment data from patients' utilization review forms (forms 485 and 486). The analysis samples consisted of 404 patients with diabetes and 876 patients who had surgical hip procedures. Significant differences were found between urban and rural areas in access to home health services. The largest differences were found in access to physical therapy services, but differences in access to skilled nursing services also exist. The data suggest that the availability of skilled care services may cause these differences.

How rural physicians compare on cost and quality measures for Medicaid ambulatory care episodes.

This study compares the costs and quality of episodes of care for two common childhood illnesses, urinary tract infections (UTI) and otitis media (OM), across providers practicing in rural, small town, and urban counties in Alabama in 1992. The data source is Medicaid claims data for children under age 8 who were treated for these conditions. The study found that episodes cared for by rural providers were less expensive than episodes cared for in other locations, both because fewer rural episodes included outpatient facility charges and because fewer ancillary services were provided in rural settings. Researchers also found that, even controlling for physician characteristics and patient demographic and utilization factors, rural episodes were significantly less likely to include two process measures of quality of care: fewer rural UTI episodes included urine cultures, and fewer rural OM episodes included follow-up visits. This study suggest that, as a group, rural physicians may have a favorable cost profile but a potentially unfavorable care content profile, compared with other physicians. Both practice profile data and explicit care recommendations need to be available to physicians so thy can monitor, defend, or alter their clinical practices.

Systematic review of mental health interventions for patients with common somatic symptoms: can research evidence from secondary care be extrapolated to primary care?

OBJECTIVES: To determine the strength of evidence for the effectiveness of mental health interventions for patients with three common somatic conditions (chronic fatigue syndrome, irritable bowel syndrome, and chronic back pain). To assess whether results obtained in secondary care can be extrapolated to primary care and suggest how future trials should be designed to provide more rigorous evidence. DESIGN: Systematic review. DATA SOURCES: Five electronic databases, key texts, references in the articles identified, and citations from expert clinicians. STUDY SELECTION: Randomised controlled trials including participants with one of the three conditions for which no physical cause could be found. Two reviewers screened sources and independently extracted data and assessed quality. RESULTS: Sixty one studies were identified; 20 were classified as primary care and 41 as secondary care. For some interventions, such as brief psychodynamic interpersonal therapy, little research was identified. However, results of meta-analyses and of randomised controlled trials suggest that cognitive behaviour therapy and behaviour therapy are effective for chronic back pain and chronic fatigue syndrome and that antidepressants are effective for irritable bowel syndrome. Cognitive behaviour therapy and behaviour therapy were effective in both primary and secondary care in patients with back pain, although the evidence is more consistent and the effect size larger for secondary care. Antidepressants seem effective in irritable bowel syndrome in both settings but ineffective in chronic fatigue syndrome. CONCLUSIONS: Treatment seems to be more effective in patients in secondary care than in primary care. This may be because secondary care patients have more severe disease, they receive a different treatment regimen, or the intervention is more closely supervised. However, conclusions of effectiveness should be considered in the light of the methodological weaknesses of the studies. Large pragmatic trials are needed of interventions delivered in primary care by appropriately trained primary care staff.

Sharing the blame: smoking experimentation and future smoking-attributable mortality due to Joe Camel and Marlboro advertising and promotions.

BACKGROUND: Despite public denials, internal tobacco company documents indicate that adolescents have long been the target of cigarette advertising and promotional activities. Recent longitudinal evidence suggests that 34% of new experimentation occurs because of advertising and promotions. OBJECTIVE: To apportion responsibility for smoking experimentation and future smoking-attributable mortality among major cigarette brands attractive to young people (Camel and Marlboro). DATA SOURCES, SETTING, AND PARTICIPANTS: Data were from confirmed never-smoking adolescents (12-17 years old) responding to the 1993 (n = 2659) and 1996 (n = 2779) population-based California Tobacco Surveys. MAIN OUTCOMES: Adolescents named the brand of their favourite cigarette advertisements and tobacco promotional items. Using these "market shares" and the relative importance of advertising and promotions in encouraging smoking, we estimated how many new experimenters from 1988 to 1998 in the United States can be attributed to Camel and Marlboro. From other data on the natural history of smoking, we projected how many future deaths in the United States can be attributed to each brand. RESULTS: Although Camel advertisements were favoured more than Marlboro and other brands in 1993 and 1996, the "market share" for promotional items shifted markedly during this period from Camel and other brands towards Marlboro. We estimated that between 1988 and 1998, there will be 7.9 million new experimenters because of tobacco advertising and promotions. This will result in 4.7 million new established smokers: 2.1, 1.2, and 1.4 million due to Camel, Marlboro, and other brands' advertising and promotions, respectively. Of these, 1.2 million will eventually die from smoking-attributable diseases: 520,000 from Camel, 300,000 from Marlboro, and the remainder from other brands. CONCLUSIONS: Our analysis provides a reasonable first estimate at sharing the blame for the long-term health consequences of smoking among the major brands that encourage adolescents to start smoking.

Studying general practice in the inner city--a model for linking available sources of data: preliminary communication.

The effect of implementing proposals intended to improve general practice primary care in inner London is not known. To test it requires a model of how general practice works and methods of measuring appropriate variables. The methods must be sufficiently simple to allow measurement prior to, as well as during, change. This paper presents such a model, describes methods used to measure some of those variables, and illustrates the results.
