Context Perioperative antibiotics are widely used to improve the outcomes of endoscopic sinus surgery. Objective The aim of this study was to summarize the evidence on the effect of perioperative antibiotic prophylaxis on outcomes of endoscopic sinus surgery. Data Sources and Review Methods We searched electronic databases from inception through May 2011 for any relevant clinical trials or observational studies. Two reviewers working independently extracted study characteristics, quality, and the outcomes of interest. Random‐effects meta‐analysis was used to pool the relative risks (RRs) and the standardized mean differences (SMDs) across trials. Results We found 4 eligible trials with varying quality, of which 3 were included in the quantitative analysis. Antibiotic prophylaxis was associated with a nonsignificant reduction in the incidence of infections (relative risk, 0.76; 95% confidence interval [CI], 0.64 to 1.09), symptoms scores (SMD, −0.04; 95% CI, −0.46 to 0.38), and endoscopic scores (SMD, −0.09; 95% CI, 0.30 to 0.13). The heterogeneity associated with the analysis was significant only for the outcome of change in symptoms score (I‐squared values, 0%, 70%, and 0% for the 3 outcomes, respectively). Conclusions Trial data available to date are unable to demonstrate a statistically significant reduction in infection, symptom scores, or endoscopic scores to support the routine use of postoperative prophylactic antibiotics following endoscopic sinus surgery. Our analysis was limited by the number of published trials related to this topic.

Adherence to recommended preventive services and immunizations in adults is suboptimal and often associated with socioeconomic status, race, and access to care. The aim of this study is to evaluate adherence in a cohort without these barriers to ascertain realistically optimal adherence rates and to examine remaining barriers among relatively advantaged individuals. Specifically, it employed a sample of 6889 patients presenting for executive health care from 2005 to 2009. Adherence varied across colorectal cancer screening (79%), mammography (89%), cervical cancer screening (91%), tetanus immunization (82%), and pneumococcal vaccination (62%). Multivariate logistic regressions revealed that age, education, alcohol use concerns, and being married were positively associated with adherence to certain services. Individuals without the usual barriers to care have variable, less-than-ideal rates of adherence to preventive services, which correlate with some health behaviors and demographics. Understanding the predictors of adherence may inform quality improvement processes aimed at optimizing disease prevention. ( Population Health Management 2012;15:65–70)
