RESUMEN

BACKGROUND: Patients managed nonoperatively have been excluded from risk-adjusted benchmarking programs, including the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP). Consequently, optimal performance evaluation is not possible for specialties like emergency general surgery (EGS) where nonoperative management is common. We developed a multi-institutional EGS clinical data registry within ACS NSQIP that includes patients managed nonoperatively to evaluate variability in nonoperative care across hospitals and identify gaps in performance assessment that occur when only operative cases are considered. METHODS: Using ACS NSQIP infrastructure and methodology, surgical consultations for acute appendicitis, acute cholecystitis, and small bowel obstruction (SBO) were sampled at 13 hospitals that volunteered to participate in the EGS clinical data registry. Standard NSQIP variables and 16 EGS-specific variables were abstracted with 30-day follow-up. To determine the influence of complications in nonoperative patients, rates of adverse outcomes were identified, and hospitals were ranked by performance with and then without including nonoperative cases. RESULTS: Two thousand ninety-one patients with EGS diagnoses were included, 46.6% with appendicitis, 24.3% with cholecystitis, and 29.1% with SBO. The overall rate of nonoperative management was 27.4%, 6.6% for appendicitis, 16.5% for cholecystitis, and 69.9% for SBO. Despite comprising only 27.4% of patients in the EGS pilot, nonoperative management accounted for 67.7% of deaths, 34.3% of serious morbidities, and 41.8% of hospital readmissions. After adjusting for patient characteristics and hospital diagnosis mix, addition of nonoperative management to hospital performance assessment resulted in 12 of 13 hospitals changing performance rank, with four hospitals changing by three or more positions. CONCLUSION: This study identifies a gap in performance evaluation when nonoperative patients are excluded from surgical quality assessment and demonstrates the feasibility of incorporating nonoperative care into existing surgical quality initiatives. Broadening the scope of hospital performance assessment to include nonoperative management creates an opportunity to improve the care of all surgical patients, not just those who have an operation. LEVEL OF EVIDENCE: Care management, level IV; Epidemiologic, level III.

RESUMEN

OBJECTIVE: We sought to compare the impact of antimicrobial impregnation to that of tunneling of long-term central venous catheters on the rates of catheter colonization and catheter-related bloodstream infection. SUMMARY BACKGROUND DATA: Tunneling of catheters constitutes a standard of care for preventing infections associated with long-term vascular access. Although antimicrobial coating of short-term central venous catheters has been demonstrated to protect against catheter-related bloodstream infection, the applicability of this preventive approach to long-term vascular access has not been established. METHODS: A prospective, randomized clinical trial in 7 university-affiliated hospitals of adult patients who required a vascular access for > or = 2 weeks. Patients were randomized to receive a silicone central venous catheter that was either impregnated with minocycline and rifampin or tunneled. The occurrence of catheter colonization and catheter-related bloodstream infection was determined. RESULTS: Of a total of 351 inserted catheters, 346 (186 antimicrobial-impregnated and 160 tunneled) were analyzed for catheter-related bloodstream infection. Clinical characteristics were comparable in the 2 study groups, but the antimicrobial-impregnated catheters remained in place for a shorter period of time (mean, 30.2 versus 43.8 days). Antimicrobial-impregnated catheters were as likely to be colonized as tunneled catheters (7.9 versus 6.3 per 1000 catheter-days). Bloodstream infection was 4 times less likely to originate from antimicrobial-impregnated than from tunneled catheters (0.36 versus 1.43 per 1000 catheter-days). CONCLUSIONS: Antimicrobial impregnation of long-term central venous catheters may help obviate the need for tunneling of catheters.

RESUMEN

BACKGROUND: No gold standard method exists for the diagnosis of ventilator-associated pneumonia despite the availability of multiple techniques. METHODS: A prospective, crossover study was performed on mechanically ventilated patients meeting with suspected pneumonia. Eighteen paired samples were obtained on 15 patients, comparing the results of quantitative tracheal lavage (QTL) to bronchoscopic protected brush specimen (PSB) by quantitative culture and gram stain examination. RESULTS: The sensitivity, specificity, positive and negative predictive values, and accuracy are affected by the growth density threshold selected, and whether the same organisms are expected by both methods. There is a significant relationship between QTL and PSB (P = 0.0048; R = 0.632), gram stain and PSB (P <0.001; R = 0.791), and gram stain and QTL (P = 0.0125; R = 0.575), by Spearman rank order correlation. CONCLUSIONS: QTL may have a role for diagnosing and directing treatment of ventilator-associated pneumonia, allowing reservation of bronchoscopic PSB for secondary, high risk and refractory cases.
