Physician leadership styles and effectiveness: an empirical study.

The authors study the association between physician leadership styles and leadership effectiveness. Executive directors of community health centers were surveyed (269 respondents; response rate = 40.9 percent) for their perceptions of the medical director’s leadership behaviors and effectiveness, using an adapted Multifactor Leadership Questionnaire (43 items on a 0-4 point Likert-type scale), with additional questions on demographics and the center’s clinical goals and achievements. The authors hypothesize that transformational leadership would be more positively associated with executive directors’ ratings of effectiveness, satisfaction with the leader, and subordinate extra effort, as well as the center’s clinical goal achievement, than transactional or laissez-faire leadership. Separate ordinary least squares regressions were used to model each of the effectiveness measures, and general linear model regression was used to model clinical goal achievement. Results support the hypothesis and suggest that physician leadership development using the transformational leadership model may result in improved health care quality and cost control.

Dual diagnosis : HIV and mental illness, a population-based study

This is a cross-sectional, population-based (n = 378,710) study using hospital discharge abstract data to determine the relative risk associated with having a dual diagnosis of mental illness and HIV/AIDS. The analysis addresses issues of gender, race, and age, as well as types of mental illness. Persons with a mental illness are 1.44 times more likely to have HIV/AIDS. Women are at increased risk of being dually diagnosed. There are no risk differences by race. Those with a specific diagnosis of substance abuse or a depressive disorder are more likely to have a diagnosis of HIV/AIDS.

Reliability of Katz's Activities of Daily Living Scale When Used in Telephone Interviews.

The reliability of afive-item Katzs Activities of Daily Living (ADL) scale collected by selfreport telephone interview is presented. A random sample of 6,472 South Carolina residents over 55 years of age selected from a statewide population is used. Factor structure, Guttman properties, internal consistency reliability, Mokkens index of test homogeneity, and Spearmans coefficient of rank-order correlation are used to show that ADL data gathered by telephone interview are reliable. Because telephone interviewing methods are faster, cheaper, and safertheyare recommended as a viable wayfor researchers, policymnakers, and practitioners to gather ADL information.

Patterns of engagement in care by HIV-infected adults: South Carolina, 2004-2006.

Objective:Identify factors associated with HIV care utilization in South Carolina. Design:Cross-sectional analysis of South Carolina nonpregnant HIV-infected individuals (N = 13 042) for the period 1 January 2004 to 31 December 2006. Methods:Reporting of HIV laboratory markers is legally mandated in South Carolina. Individuals with reported viral load tests or CD4 cell counts during a calendar year were defined as ‘in HIV-medical care’ that year. Care utilization categories were in care, care all 3 years; not-in-care (NIC), no care received; and transitional care, during some but not all years. Multinomial logistic regression using generalized logits was used to estimate relationships between care utilization and predictor variables. Results:Five thousand, two hundred and seventeen (40.0%) of South Carolina HIV-infected adults were NIC and 3300 (25.3%) were in transitional care during 2004–2006. Although a larger number of black than white HIV-infected adults were NIC, adjusted odds for NIC status were lower among blacks than whites [adjusted odds ratio (AOR), 0.82; 95% confidence interval 0.74, 0.92)]. Women had lower odds of being NIC than men (AOR, 0.66; 95% confidence interval 0.58, 0.74). Compared with individuals 55 years or older, individuals who were 25–34 years old were most likely to demonstrate both the NIC (AOR, 1.85; 95% confidence interval 1.29, 2.65) and transitional (AOR, 1.85; 95% confidence interval 1.31, 2.62) care patterns. Conclusion:Large proportions of the South Carolina HIV-infected adult population are not consistently accessing HIV-medical care. Targeted programs are needed to improve engagement for HIV-infected adults most likely to transition or not be in care.

A Measure of Perceived Burden among Caregivers

This, report describes an easily administered scale for measuring perceived burden among caregivers offamily members with dementia. During home interviews conducted in 1991, 82 caregivers rated theirfamily member with dementia on several items related to functional ability, the type of care provided, and associated stress. The resulting measure ofperceived burden, based on 15 internally consistent items (alpha = 0.87), is significantly correlated with depressive symptomatology (r = 0.38, p = 0.0004). This measure is useful in assessing perceived stress associated with specific caregiving responsibilities. It can be used, along with other measures of patientfunctional status, to assess overall caregiver burden and to target intervention strategies.

Factors Affecting Health Status in African Americans Living with HIV/AIDS

This study surveyed face-to-face 111 African American newly diagnosed and living with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) from the Washington D.C. area, to ascertain the use of, and need for, early intervention services. The survey instrument included sections on demographics, level of health functioning and health indicators, social and financial support, and needed services. This article constructs a health status proxy variable from survey items and examines its relationship to biological and social variables. Variables found to have a significant relationship with health status are gender, type of health insurance, employment, receiving Social Security Disability Income, and level of education. A log-linear model for selection of parsimony found that the type of health insurance was most highly predictive of health status, when controlling for other variables. Persons who receive Medicaid report no better levels of health status than those without health insurance. Having private health insurance is associated with a 5.3-fold greater chance of having good or excellent health status.

The association of positive and negative events with depressive symptomatology among caregivers

A pilot study of eighty-two caregivers was conducted in South Carolina in 1991 to identify positive and negative factors associated with caregiving. Through home visits, interviewers obtained data on a variety of physical and mental health measures, including two new scales designed to measure perceived “positive” and “negative” events that had occurred in the previous month. The Center for Epidemiologic Studies Depression scale was used as a measure of depressive symptomatology. For the new scales, only items that were significantly correlated with depressive symptomatology (p < 0.01) were retained. The new “positive” event scale (8 items) and the new “negative” event scale (16 items) had alpha coefficients of 0.79 and 0.86, respectively. These scales may be useful to researchers in sorting out mediating factors related to the burden of caregiving and in providing points for intervention.

Reducing the Numbers of the Uninsured: Policy Implications from State-Level Data Analysis

The objective of the study described in this article was to identify a model that best predicts state uninsurance rates and quantifies the contribution of socio-economic factors to enable targeted state programs to reduce uninsurance. Linear regression analysis was carried out using state uninsurance rate as the dependent variable and state-level data on demographic, employment, income, and health care environment data (independent variables). For 2000 data, the model R is 0.77, indicating that 77% of the variation in uninsurance rates is explained by the percentage of immigrant population, the workforce in very small businesses, the Black population, the states median income, and the Medicare-aged population (model R = 0.77 for 1999 and 0.68 for 1998 data). A 1% increase in immigrant population is associated with 0.18% increase in uninsurance rate. A 1% increase in workforce employed in very small businesses associates with 0.79% increase in uninsurance. The findings indicate substantial potential for reducing uninsurance through targeted state policies. Policy recommendations are made to alleviate the insurance hurdles faced by immigrant and small business employee populations.

Factors affecting total hospital charges and utilization for South Carolina inpatients with HIV/AIDS in 1994-1996,.

This studys analysis addresses trends in hospital utilization and costs for patients with human immunodeficiency virus acquired immunodeficiency syndrome (HIV/AIDS) from 1994 through 1996 in South Carolina, as well as the effect of patient sociodemographics, referrals, and provider characteristics. This is a population-based study of all emergency department visits and hospitalizations occurring during that time period. The total hospital charge per patient significantly increases over time, while the total inpatient days per patient decreases significantly, and the charge per day increases significantly. The proportion of patients with public insurance or who are indigent is increasing, and the proportion of those with private insurance is decreasing. Other variables that have a significant impact on total hospital charges, total inpatient days, and charges per day are types of insurance, physicians specialty, discharge status, and number of diagnoses (severity). Persons who are Medicare eligible are sicker and have higher hospital costs and more inpatient days when compared to those with Medicaid. Intensity of services (hospital charges per day) is associated with private insurance and self-pay patients. Persons with terminal illness stay longer and have higher costs. When HIV/AIDS is the primary admitting diagnosis, there are higher hospitalization costs. Increasing severity of illness (number of diagnoses) leads to higher total hospital charges and days. With the introduction of new AIDS treatments in 1996, further study is required to determine the effects of new drugs, physician specialties, and other provider characteristics on the cost and utilization of health care services, both inpatient and outpatient.

Findings from a Demonstration Outreach Project at a Community Health Center

Outreach using personal contact was a cornerstone of the federally funded Community Health Center (CHC) movement of the 1960s. Funding cuts and changes in federal policy have led to the discontinuation of this activity in most CHCs. This paper assesses aspects of a demonstration outreach project designed to encourage use of a CHC in Orangeburg, South Carolina. The evaluation shows that this type of outreach effort, which includes door-to-door canvassing, can identify specific needs for primary health care services in a poor under served community, and can enhance community access to Medicaid, although the financial impact of bringing poor patients into CHCs by means of this type of outreach is relatively low.
