Focus group data as a tool in assessing effectiveness of a hand hygiene campaign.
BACKGROUND: Routine handwashing has been proven to decrease incidence of health care-associated infections, including methicillin-resistant Staphylococcus aureus (MRSA), spawning numerous attempts to "advertise" its importance. However, most control measures fail to evaluate systematically the efficacy of handwashing initiatives. The purpose of this study was to implement a hand hygiene program in an academic medical center, utilizing visual cues developed with periodic input from hospital personnel. METHODS: After estimation of baseline compliance (20%), visual cues in the form of 11'' x 17'' posters were developed in a sequential fashion, based on suggestions from participants. The stepwise approach was supported by data collected via focus groups. These data were used to design target-specific messages and to understand better the benefits of utilizing participant input. RESULTS: Postexposure compliance rates indicated a modest improvement over baseline, increasing to 37% during the 12-month study. In addition, the stepwise design proved to be highly useful in guiding the intervention process. Analysis of qualitative data also elucidated numerous routes through which effective hand hygiene campaigns could be implemented. CONCLUSIONS: Through diligent observation and participant feedback, the research team was able to develop and market educational cues to meet service demands of health care professionals in a unified effort to control health care-associated infections. Future interventions should employ incremental evaluation designs supported by participant input to develop effective hand hygiene initiatives.

Factors associated with the treatment of latent tuberculosis infection among health-care workers at a midwestern teaching hospital.
STUDY OBJECTIVE: To assess factors associated with initiating therapy and compliance with treatment for latent tuberculosis infection among health-care workers with positive tuberculin skin test results. DESIGN: Prospective cohort study. SETTING: An urban midwestern teaching hospital in St. Louis, MO. STUDY POPULATION: Health-care workers with positive tuberculin skin test results. MEASUREMENTS: (1) Rates of initiating therapy for latent tuberculosis infection among all health-care workers with positive tuberculin skin test results, and (2) compliance rates with therapy for latent tuberculosis infection among health-care workers with recent tuberculin skin test conversion. RESULTS: A total of 440 tuberculin skin test-positive health-care workers were evaluated from January 1, 1994, to May 1, 2000. Of those evaluated, 1 health-care worker had presumed active tuberculosis, 1 had no record of being evaluated, 1 had missing records, and 33 were not recommended isoniazid therapy, leaving 404 workers for analysis. Overall, 396 of 404 health-care workers (98%) with positive tuberculin skin test results initiated isoniazid therapy. In univariate analysis, bacille Calmette-Guérin (BCG) vaccination (p = 0.02) and foreign birth (p = 0.03) were significantly associated with not initiating isoniazid therapy. Compliance data were available for 388 of 404 health-care workers (96%). Of these, 318 of 388 health-care workers (82%) were compliant with 6 months of therapy. BCG vaccination (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.8 to 7.1) and symptoms while receiving therapy (OR, 4.5; 95% CI, 2.0 to 10.1) were significantly associated with noncompliance in multivariate analysis. Among new converters, Asian race (p = 0.006), foreign birth (p = 0.01), BCG vaccination (p = 0.006), and symptoms while receiving therapy (p < 0.001) were significantly associated with noncompliance in univariate analysis. CONCLUSION: This hospital had a high rate of initiating isoniazid therapy for tuberculosis infection among their health-care workers, and a high rate of compliance with therapy. These rates of initiation and completion of isoniazid therapy were much higher than those previously reported in the literature. This may be largely due to a focused program, which includes active follow-up of health-care workers with positive tuberculin skin test results, consisting of physician counseling and monthly phone consultations by nurses, along with free services and medications provided on-site.
