Validation of scale measuring environmental barriers to diabetes-regimen adherence.

This study reports on the validation of a diabetes-specific measure of environmental barriers to regimen adherence. The reliability and validity of the environmental barriers to adherence scale (EBAS) were determined for a sample of 214 insulin-dependent and non-insulin-dependent diabetic patients. The scale was shown to be a valid measure of barriers to adherence as assessed by its relationship to the barriers to adherence questionnaire and the barriers to adherence portion of the diabetes-care profile. The medication, testing, exercise, and diet subscales of the EBAS were correlated with four corresponding and three noncorresponding measures of self-care behavior from the diabetes self-care behaviors scale. Each subscale correlated well with its corresponding self-care behavior. The internal consistency of the scale and the test-retest reliability were found to be good. The results suggest that the EBAS scale is a valid, reliable measure of barriers to diabetes-regimen adherence.

Fear of hypoglycemia: relationship to physical and psychological symptoms in patients with insulin-dependent diabetes mellitus.

Among diabetic patients, experience with hypoglycemia ranges from the unpleasant to the life threatening. The aversiveness of these episodes often results in fear. To examine the impact of hypoglycemia on fear, 69 patients with insulin-dependent diabetes mellitus completed the Behavior and Worry subscales of the Hypoglycemia Fear Survey along with measures of psychological symptoms, perceived stress, risk of future hypoglycemic episodes, and glycosylated hemoglobin. Behavior and Worry scores were positively related to psychological symptoms, perceived stress, and previous experiences with hypoglycemia. Fear was unrelated to glycosylated hemoglobin but was significantly higher for patients who had greater variability and lower mean daily blood glucose.

Impact of community-based diabetes education on program attenders and nonattenders.

This study reports on the differential impact of a moderately intensive diabetes education program on program attenders and dropouts. Sixty-one individuals with diabetes mellitus participated in a diabetes education program to increase knowledge, self-care, and metabolic control. Program attenders demonstrated a significant increase in diabetes knowledge and foot care irrespective of whether they attended the control or education groups. A discriminant analysis suggested that the nonattenders were more poorly educated, had less income, were younger, had had diabetes twice as long, reported more barriers to self-care, and were in poorer health than attenders. These results suggest that patients who attend interventions may be able to benefit from even minimal levels of intervention, while program dropouts may need special assistance to overcome obstacles to program participation.

Out of the Ivory Tower: the value of collaborative research.

Collaboration is an underutilized strategy for combining the strengths and perspective of home health care professionals in service and academic settings. This paper explores the importance of collaborative research strategies, focusing on the role of the unique talents, resources, and perspectives offered by each health professional to the research process. Finally, personal, professional and organizational barriers to collaboration are examined in order to alert would-be researcher collaborators to obstacles they are likely to encounter. When both the strengths of and obstacles to collaborative research are anticipated, collaboration can encourage research that is relevant to the needs and experiences of both home health service providers and academicians.

Predicting utilization of home health resources. Important data from routinely collected information.

This study examined the feasibility of using routinely collected information on patients enrolled in home health care to predict their subsequent use of services. Data were gathered from 1,984 episodes of care randomly sampled from home health care agencies of the Virginia Health Department. Age, sex, Medicare and Medicaid enrollment, referral source, medical diagnosis, and prognosis were used to predict the total number of visits, the duration of enrollment, and the intensity of service. Since the data were originally gathered to study the effects of the implementation of diagnosis-related groups (DRGs) on home health services, half of the patients were enrolled before and half after the implementation of DRGs. Using multiple linear regression analysis, significant amounts of variance in each measure of home health care utilization were explained by the predictor variables (R2 = 0.04 to 0.10). For example, after controlling for other predictor variables, age 75 years or older predicted longer durations of enrollment and lower intensities of service as compared with other age groups (P less than 0.05), and four of 14 diagnosis categories predicted at least one measure of utilization (P less than 0.05). Medicaid enrollment predicted longer durations of enrollment and lower intensities of service in home health care (P less than 0.05) in the post-DRG but not the pre-DRG period. These results demonstrate the value of routinely collected information in predicting the use of home health services. To develop more accurate estimates of needs for home health services for particular groups of patients, additional information on chronic functional impairments, informal caregiving, and the chronicity of needs may be useful.
