Computer assisted instruction for preoperative and postoperative patient education in joint replacement surgery.

This article describes a comprehensive system for preoperative and postoperative patient education. The system offers a cost-effective method of instruction which encourages patient interaction and practice with decision making. The system was designed for patients undergoing total joint replacement surgery and includes two preoperative lessons, and a third lesson presented postoperatively at the bedside. The computer lessons were developed using data collected by a patient assessment instrument, and collaboratively with input from a nurse clinical specialist, orthopedic surgeon, physical therapist, and computer programmer. In this project, several advantages for using computer assisted instruction for preoperative and postoperative patient education were identified.

Data-based planning for educational interventions through hypertension control programs for urban and rural populations in Maryland.

As part of a statewide effort to coordinate existing resources for high blood pressure (HBP) control, a public health HPB control program was planned and implemented in two high-risk communities in Maryland. The selection of the two communities was based on epidemiologic data. The planning of the educational intervention program in these communities (urban and rural) was guided by organizational theory and health education principles. The framework for development, implementation, and evaluation of the program utilizes an educational assessment model which identified factors that predispose, reinforce, and enable individual persons to practice positive health behavior. Multiple data sources were used in assessing the extent of the problem and relevant approaches in the development of the coordinated HPB control program. These include statewide vital statistics and a random statewide household survey to assess the prevalence rates of awareness, treatment, and control of HPB. To supplement these data, telephone surveys were carried out in the two communities to assess knowledge, beliefs, and practices related to HPB control. Medical record reviews provided baseline information on appointment keeping behavior and BP correlates of hypertensive patients. The planning and implementation of the program was carried out under the direction of representatives of the health care systems, community leaders, and residents, and representatives of communitywide organizations involved in HPB control.

Barriers to condom use and needle cleaning among impoverished minority female injection drug users and partners of injection drug users.

This study was undertaken to describe sexual behaviors and drug use and other factors that inhibit condom use and needle cleaning among impoverished women who are injection drug users (IDUs) or sexual partners of IDUs. This study also investigated whether risky sexual behavior or barriers to risk reduction differ with ethnicity and level of acculturation. Survey instruments to assess drug and sexual activity were administered to 378 African American and Latina women recruited primarily from homeless shelters and drug recovery programs. The most commonly cited barriers to condom use were belief that partners did not have acquired immunodeficiency syndrome (AIDS), lack of knowledge about where to get and how to use condoms, and discomfort discussing condom use with partners. African American women were more likely to report having multiple partners and unprotected sex, and more likely to report barriers in using, discussing, and obtaining condoms. Latina women were more likely to report partners' dislike of condoms. African American and highly acculturated Latina women were more likely to be IDUs than less acculturated Latina women. The most pervasive barriers for needle cleaning were not having personal needles, being high and not interested in needle cleaning, and not having disinfectant available. In a multiple logistic regression analysis for engaging in unprotected sex and cleaning needles, not ethnic or acculturation differences were found after controlling for selected demographic characteristics and risk factors. The data indicate a need to increase the supply of free or low cost condoms, to provide easily accessible sites for obtaining condoms, to supply clean needles,and to focus counseling for women on negotiating condom use with partners and the skillful and correct placement of the condom.

Putting medical practice guidelines into practice: the cholesterol model.

As more and more medical practice guidelines are developed in the United States, commensurate evaluation efforts should assess their impact on professional practice and patient outcomes. We describe an ongoing research program designed to develop and test practice models for applying the 1988 Adult Treatment Panel Guidelines for the clinical management of high blood cholesterol. Four studies are evaluating different models to assist nonacademic community practices in the detection, evaluation, and treatment of high blood cholesterol. We have designed randomized controlled trials set in solo and small-group primary care practices of family or general practitioners and internists situated in rural, suburban, and urban settings. Patients include adult men and women who represent diverse socioeconomic and ethnic backgrounds. We are measuring rates of cholesterol screening; dietary and drug treatment and follow-up; changes in dietary intake and compliance with drug therapy; changes in quality of life and cost of intervention; and reduction in cholesterol level. Scheduled for completion in 1994, this program will provide insights into practical and effective methods of lipid management. It serves as a model for studying the application of health guidelines in the context of nonacademic primary care practices serving diverse patient populations.
