Self-efficacy and health education.

Abstract: Bandura's theory of self-efficacy has been applied in many areas of health education including smoking cessation, pain control, eating problems, cardiac rehabilitation, and adherence to regimens. Consequently, self-efficacy has emerged as an important concept with which health educators should be familiar. Self-efficacy refers to one's belief in the ability to do a specific behavior. Self-efficacy is a principle connection between knowledge and action since the belief that one can do a behavior usually occurs before one actually attempts the behavior. Self-efficacy also affects the choice of behavior, settings in which behaviors are performed, and the amount of effort and persistence to be spent on performance of a specific task. This article will examine self-efficacy theory, describe sources of self-efficacy, and present applications of self-efficacy theory.

Community Hospital-based Stroke Programs: North Carolina, Oregon, and New York. III. Factors influencing survival after stroke: proportional hazards analysis of 4219 patients.

Abstract: The possible effect of age, race, sex, consciousness upon admission, geographic location, and history of selected risk factors on the survival after stroke due to infarction or hemorrhage was determined using proportional hazards analysis (Cox regression). For each diagnostic category the most significant prognostic factor was consciousness upon admission. Increasing age, cardiac disease, or previous stroke also decreased the survival time of patients with infarctions. For patients with cerebral hemorrhage, no other variable was significant after control for consciousness level.

Community Hospital-based Stroke Programs: North Carolina, Oregon, and New York. I: Goals, objectives, and data collection procedures.

Abstract: In order to assess the impact of variations in stroke care on outcomes, and to make geographic comparisons, the three Community Hospital-Based Stroke Programs in North Carolina, Oregon, and New York, aggregated their data on 4,132 hospitalized stroke patients. Complete demographic data or "Major Profile" were obtained on 2,390 (57.8%) of the 4,132 stroke patients. This includes those patients on whom informed patient and physician consents were obtained during the hospitalization. Of the major profile patients, 1,490 (62.3%) were followed for periods up to one year, 502 (21.0%) were lost to followup and 398 (16.6%) died within the one year followup period. Incomplete demographic data or "Minor Profile" were observed on 1,742 (42.1%) of the 4,132 patients. Minor profile includes those who died before comprehensive interviews were completed or those for whom informed consent for an interview could not be obtained. Of the minor profile group, 813 (46.7%) died in hospital, and 929 (53.3%) were alive when discharged from the hospital. This paper, which describes the programs, data collection procedures, and study cases, also highlights specific issues on stroke diagnosis, risk factors associated with stroke, and the influence of interventions on stroke outcomes. We conclude that: 1) the merging of data on hospitalized stroke cases from rural and urban hospitals in geographically distinct regions can be used in the study of stroke diagnosis, the use of diagnostic tests, and the effect of interventions on stroke outcomes; and 2) these data are consistent with the hypothesis that part of the national decline in mortality from stroke is due to a decline in stroke severity.

Community Hospital-based Stroke Programs: North Carolina, Oregon, and New York. II: Description of study population.

Abstract: The three Community Hospital-based Stroke Programs collected data on 4132 stroke patients admitted to acute care hospitals during 1979 and 1980. White female stroke patients were older than the white male, nonwhite female and nonwhite male stroke patients. Nearly one-fourth (23%) of stroke patients were employed at the time of the event. Most (77%) of the patients were hospitalized for first stroke episodes. Eighty-three percent of the patients had at least one of the four major risk factors for stroke, namely, hypertension, diabetes, transient ischemic attacks and cardiac disease. Half (49%) of the patients were alert at the time of admission. The three diagnostic categories included infarction (60%), stroke not otherwise specified (30%) and hemorrhage (10%). Fourteen days was the median length of hospitalization; 50% of the stroke patients were discharged to a home setting, 31% were institutionalized and 19% died while in the hospital. The mean Barthel Index score for 2400 patients at the time of discharge was 61.8 (normal is 100). Of those patients who were working at the time of the stroke, 22% returned to work. In comparison to the patients in the National Survey of Stroke, patients in this Study were less severe at the time of admission (49% of patients in the National Survey of Stroke were stuporous or comatose compared to 21% of the patients in the current Study). The inhospital fatality was 30.7% in the National Survey of Stroke, and 19.7% in the current Study.

Evaluation of the North Carolina Stroke Care Program.

Abstract: A study of 774 patients in eastern North Carolina was undertaken to determine the effects of a coordinated program of care and follow-up on recovery from stroke. The program was designed to coordinate and improve in-hospital stroke care and rehabilitation, to provide for education and training of the family for post-hospital care, and to coordinate and facilitate continued access to services after discharge. As measured by the Barthel Index at discharge, three, six and 12 months, the impact of the program was found to be minimal. Patients' scores throughout follow-up were influenced by age, whether the stroke event was new or recurrent, and the state of consciousness at admission. Follow-up Barthel scores were also related to scores obtained at discharge.

Choice of payment plan in the Medicare capitation demonstration.

Abstract: This article identifies factors that influence the choice between joining an HMO and remaining with the traditional fee-for-service system among aged Medicare beneficiaries in three communities. Sources of marketing information were found to be strongly and positively related to the decision to join the HMO. Among beneficiaries who had to switch providers to join, persons who had a prior usual source of care and those who were satisfied with the amount of paperwork required to use that source of care were less likely to enroll in the HMO. Persons who did not have to switch providers to join the HMO were more likely to enroll in the prepaid program if they were satisfied with the amount of paperwork involved in using the HMO prior to the demonstration. Differences among the three communities suggest that the barrier to HMO enrollment presented by having a prior source of care who is not affiliated with the HMO may attenuate as the number of competing HMOs in the community increases, making the medical care environment more competitive. In the community with the most HMOs, persons who already had supplemental insurance were less likely to enroll than those who did not. None of the six HMOs studied experienced adverse selection, based on pre-enrollment health status.
