N2 - Background: Studies disagree whether surveillance bias is associated with perioperative venous thromboembolism (VTE) performance measures. A prior VA study used a chart-based outcome; no studies have used the fully specified administrative data-based AHRQ Patient Safety Indicator, PSI-12, as their primary outcome. If surveillance bias were present, we hypothesized that inpatient surveillance rates would be associated with higher PSI-12 rates, but with lower post-discharge VTE rates. Methods: Using VA data, we examined Pearson correlations between hospital-level VTE imaging rates and risk-adjusted PSI-12 rates and post-discharge VTE rates. To determine the robustness of findings, we conducted several sensitivity analyses. Results: Hospital imaging rates were positively correlated with both PSI-12 (r = 0.24, p = 0.01) and post-discharge VTE rates (r = 0.16, p = 0.09). Sensitivity analyses yielded similar findings. Conclusions: Like the prior VA study, we found no evidence of PSI-12-related surveillance bias. Given the use of PSI-12 in nationwide measurement, these findings warrant replication using similar methods in the non-VA setting. Summary for Table of Contents:We examined whether there was surveillance bias associated with hospital level measurement of the Agency for Healthcare Research and Quality Patient Safety Indicator, Perioperative Pulmonary Embolism and Deep Vein Thrombosis (PSI-12). We hypothesized that if surveillance bias were present, inpatient surveillance imaging rates would be associated higher PSI-12 rates, but with lower post-discharge venous thromboembolism (VTE) rates. However, we found a statistically significant positive association between imaging and PSI-12 rates, and a positive, albeit weaker association between imaging and post-discharge VTE rates. Similar patterns were seen across all sensitivity analyses; these findings argue against surveillance bias.
