Influence of socioeconomic status on trauma center performance evaluations in a Canadian trauma system.
Trauma center performance evaluations generally include adjustment for injury severity, age, and comorbidity. However, disparities across trauma centers may be due to other differences in source populations that are not accounted for, such as socioeconomic status (SES). We aimed to evaluate whether SES influences trauma center performance evaluations in an inclusive trauma system with universal access to health care. ⋯ We observed an important variation in SES across trauma centers but no change in risk-adjusted mortality estimates when SES was added to adjustment models. Results suggest that after adjustment for injury severity, age, comorbidity, and transfer status, disparities in SES across trauma center source populations do not influence trauma center performance evaluations in a system offering universal health coverage.

Are targeted preoperative risk prediction tools more powerful? A test of models for emergency colon surgery in the very elderly.
Whether preoperative risk prediction improves with the use of more patient- and procedure-targeted models is unclear. We created a customized preoperative mortality risk prediction score for patients 80 years or older needing an emergency colectomy and compare it with existing, more generic risk assessment methods. ⋯ Our study presents a validated preoperative mortality score for very elderly patients needing an emergency colectomy. The greater discriminating power of this targeted score indicates that preoperative risk assessment may need to be customized to specific procedures and patient circumstances.

How valid is the AHRQ Patient Safety Indicator "postoperative hemorrhage or hematoma"?
Postoperative hemorrhage or hematoma (PHH), an Agency for Healthcare Research and Quality Patient Safety Indicator, uses administrative data to detect cases of potentially preventable postsurgical bleeding requiring a reparative procedure. How accurately it identifies true events is unknown. We therefore determined PHH's positive predictive value. ⋯ PHH's accuracy could be improved by coding enhancements, such as adopting present on admission codes or associating a timing factor with codes dealing with bleeding control. The ability of PHH to identify events representing quality of care problems requires additional evaluation.

Validity of the AHRQ Patient Safety Indicator "central venous catheter-related bloodstream infections".
"Central venous catheter-related bloodstream infections" (CR-BSIs) is one of the patient safety indicators (PSI 7) developed by the Agency for Healthcare Research and Quality (AHRQ) to screen for potential safety events. We sought to investigate the validity of this PSI using the medical record as the gold standard. ⋯ PSI 7 has relatively poor predictive ability for identifying true events. Coding-related issues were the main reason for the low PPV. Implementing POA codes and using more specific ICD-9-CM codes would improve its validity. As it currently stands, PSI 7 should not be used as a pay-for-performance measure, but should be limited to use in internal quality improvement efforts.

Variation in quality of care after emergency general surgery procedures in the elderly.
The elderly (age ≥65 years) comprise an increasing proportion of patients undergoing emergency general surgery (EGS) procedures and have distinct needs compared with the young. We postulated that the needs of the elderly require different processes of care than those required for the young to assure optimal outcomes. To explore this hypothesis, we evaluated 30-day outcomes following EGS procedures in the young and the elderly and determined whether hospital performance was consistent across these 2 age strata. ⋯ Elderly patients are at substantially greater risk for adverse events following EGS procedures. Hospitals had only slight agreement in mortality outcomes in the elderly compared with those in young patients. Processes of care that may account for this disparity should be further investigated.
