Slide Presentation from the AHRQ 2007 Annual Conference

Results

• Cross-section and pre-post conversion comparisons showed that critical access hospital (CAH) had better performance of patient safety than rural PPS hospitals.
• The odds ratios of poor performance in CAHs compared to rural PPS hospitals are 0.30 (CI: 0.14-0.64) for PSI-6, 0.29 (CI: 0.15-0.56) for PSI-7, 0.40 (CI: 0.24-0.67) for PSI-15, and 0.49 (CI: 0.31-0.80) for composite score of 4 PSIs. CAH conversion had no significant impact on the observed rates of foreign body left during procedure.
• Moving average CAH indicator had larger effects than binary CAH scale.
• Sensitivity analyses using tobit models consistent results
• Findings were robust among sensitivity analyses using different samples and different methods
