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.

Positive predictive value of the AHRQ Patient Safety Indicator "postoperative wound dehiscence".
The Agency for Healthcare Research and Quality patient safety indicator (PSI) 14, or "postoperative wound dehiscence," is 1 of 4 PSIs recently adopted by the Centers for Medicare & Medicaid Services to compare quality and safety across hospitals. We determined how well it identifies true cases of postoperative wound dehiscence by examining its positive predictive value (PPV). ⋯ PSI 14 has relatively good predictive ability to identify true cases of postoperative wound dehiscence. It has the highest PPV among all PSIs evaluated within the Veterans Health Administration system. Inaccurate coding was the reason for false positives. Providing additional training to medical coders could potentially improve the PPV of this indicator. At present, this PSI is a promising measure for both quality improvement and performance measurement; however, its use in pay-for-performance efforts seems premature.

Detecting patient safety indicators: How valid is "foreign body left during procedure" in the Veterans Health Administration?
The Agency for Healthcare Research and Quality (AHRQ) developed patient safety indicator (PSI) 5, "Foreign body left during procedure," to flag accidental foreign bodies in surgical and medical procedures. This study examined how well this indicator identifies true foreign body events in the Veterans Health Administration (VA). ⋯ The reported rate of foreign body events as detected by PSI 5 is low in the VA, but occurs in both surgical and medical procedures. Despite widespread implementation of surgical counts, quality improvement efforts should focus on novel ways to eliminate this "never event" from operations. Future studies are needed to better understand the preventability of medical procedure-associated foreign bodies and particularly, device failure-related foreign bodies.

The Agency for Healthcare Research and Quality (AHRQ) recently designed the Patient Safety Indicators (PSIs) to detect potential safety-related adverse events. The National Quality Forum has endorsed several of these ICD-9-CM-based indicators as quality-of-care measures. We examined the positive predictive value (PPV) of 3 surgical PSIs: postoperative pulmonary embolus and deep vein thrombosis (pPE/DVT), iatrogenic pneumothorax (iPTX), and accidental puncture and laceration (APL). ⋯ Until coding revisions are implemented, these PSIs, especially pPE/DVT, should be used primarily for screening and case-finding. Their utility for public reporting and pay-for-performance needs to be reassessed.

Comparative Study
Molecular diagnosis of response to neoadjuvant chemoradiation therapy in patients with locally advanced rectal cancer.
Pathologic complete response (pCR) to neoadjuvant chemoradiation (CRT) is an important prognostic factor in locally advanced rectal cancer. However, it is uncertain if histopathological techniques accurately detect pCR. We tested a novel molecular approach for detecting pCR and compared it with current histopathological approaches. ⋯ Sensitive molecular techniques detect K-ras and p53 mutations in post-CRT surgical specimens in some patients with a pCR. This suggests histopathological techniques might not be completely accurate, and some patients diagnosed with a pCR to CRT might have occult cancers cells in their surgical specimens.
