Prolonging the return visit interval in primary care.

PURPOSE: Extending the scheduled return visit interval has been suggested as one means to improve clinic access to the provider. However, prolonging the return visit interval may affect quality of care if prevention measures and chronic disease management receive less attention as clinic visits become less frequent. The purpose of this study was to determine whether a comprehensive education program could encourage providers to lengthen their return visit interval without compromising performance on key quality indicators. SUBJECTS AND METHODS: This was a prospective cohort study monitoring scheduling and performance data of primary care providers at the Milwaukee Veterans Affairs Medical Center. Following collection of baseline data (January through June 1999), providers were encouraged to lengthen the return visit interval while increasing reliance on nurses and other clinic staff for interim management of chronic disease. Provider-specific feedback of return visit interval and performance data was utilized to motivate behavioral change. Scheduling and clinical data were abstracted from random medical record audits performed at baseline and from July through December in the years 2000 and 2001. RESULTS: Compared with the baseline period, the percent of patients scheduled > or =6 months was significantly increased among staff providers and medicine residents at 2 years (Staff providers: 31% vs. 62%, P <0.001; Medicine residents: 22 vs. 44%, P <0.001). Colorectal screening, pneumonia immunizations, and achievement of therapeutic goals for diabetes, hypertension, and lipid disorders significantly improved at 2 years compared with baseline measurements. CONCLUSIONS: Educational interventions can successfully retrain providers to extend the return visit interval and reduce the scheduling of routine and perhaps unnecessary appointments. This can be accomplished without compromising important performance monitors for diabetes, lipid disorders, hypertension, and prevention.

Analysis of Web access logs for surveillance of influenza.

The purpose of this study was to determine whether the level of influenza in a population correlates with the number of times that internet users access information about influenza on health-related Web sites. We obtained Web access logs from the Healthlink Web site. Web access logs contain information about the user and the information the user accessed, and are maintained electronically by most Web sites, including Healthlink. We developed weekly counts of the number of accesses of selected influenza-related articles on the Healthlink Web site and measured their correlation with traditional influenza surveillance data from the Centers for Disease Control and Prevention (CDC) using the cross-correlation function (CCF). We defined timeliness as the time lag at which the correlation was a maximum. There was a moderately strong correlation between the frequency of influenza-related article accesses and the CDC's traditional surveillance data, but the results on timeliness were inconclusive. With improvements in methods for performing spatial analysis of the data and the continuing increase in Web searching behavior among Americans, Web article access has the potential to become a useful data source for public health early warning systems.
