HIV prevention in primary care: impact of a clinical intervention.

Discomfort, lack of confidence in skills, and environmental constraints may cause primary care providers to miss opportunities to discuss human immunodeficiency virus (HIV) risk with patients. We used a systems approach to address both intrapersonal and environmental barriers to HIV risk assessment and prevention counseling in a managed care clinical setting. The design was one-group pretest/posttest. The study took place in two primary care clinics of a large Pacific Northwest managed care organization. Participants (n = 49) included physicians, physician assistants, nurse practitioners, registered nurses, and social workers. The intervention included training, clarification of provider/staff roles, assess to tools and materials, and reminders/reinforcers. Outcome measures were provider attitudes, beliefs, outcome expectations, knowledge, confidence in skills, and perceived supports and barriers, measured by written pretest/posttest surveys administered 12 months apart. Seven months after the most intensive part of the intervention, providers' attitudes and beliefs were more favorable to HIV risk assessment and prevention counseling. They were less likely to express frustration with high-risk patients (decrease from 100% to 79% agreement, p = 0.001) and more confident that their advice would be effective with gay men and single adult heterosexuals (p = 0.002 and 0.005, respectively). They reported more confidence in their training in sexual history taking (p = 0.0003) and their skills assessing readiness for change (p = 0.007), and more support in practice environments. This study demonstrated that it is possible to affect important personal and environmental factors that influence primary care providers' HIV prevention behavior using an interactive, real-world systems approach. Further research is needed on providers' impact on patient behavior.

Enhancing primary care HIV prevention: a comprehensive clinical intervention.

CONTEXT: Human immunodeficiency virus (HIV) and sexually transmitted disease (STD) risk assessment and counseling are recommended for a large proportion of the population, yet measured rates of such counseling remain low. OBJECTIVE: Use a comprehensive intervention to improve and sustain rates of HIV/STD risk assessment and counseling by providers. DESIGN: Patient telephone survey using a one-group pre- and post-intervention design with measurements over a 62-week period. SETTING AND PARTICIPANTS: Patients (N=1042) from two outpatient clinics at a health maintenance organization (HMO) presenting for either of two types of index visit: symptomatic (n=210), or routine physical examination or birth control (n=832) visits. MAIN OUTCOME MEASURES: Telephone survey performed within 3 weeks of the index visit. Patients' recall of a general discussion of HIV/STDs and specific discussion of sexual behaviors/risk factors. RESULTS: The intervention was associated with increased patient recall of providers: discussing HIV/STD in general (OR 1.6; 95% CI, 1.12-2.22), asking about sexual behaviors/risk factors (OR 1.7; 95% CI, 1.2-2.6), discussing HIV prevention generally (OR 2.4; 95% CI, 1.4-4.0), and discussing personal risk reduction (OR 2.6; 95% CI, 1.6-4.3). Provision of written materials concerning HIV/STD also increased significantly (OR 2.8; 95% CI, 1.3-4.3). A clear-cut pattern of improved provider effort was seen, with the most pronounced improvements in high-risk patients. Results were stable over a 38-week follow-up period. CONCLUSION: A sustained improvement in HIV/STD risk assessment and counseling can be achieved in an outpatient HMO setting using a relatively non-intensive systematized intervention.
