Diarrhea and Clostridium difficile-associated diarrhea on a surgical service.

OBJECTIVE: To identify the incidence, risk factors, and treatment of diarrhea and Clostridium difficile-associated diarrhea (CDAD) in surgery patients. DESIGN: Prospective and historical retrospective analysis. SETTING: Major urban tertiary care referral hospital. PATIENTS: Consecutive patients (N = 475) admitted to the vascular, trauma, and general surgical surgery services, prospectively evaluated during a 10-week period. A retrospective historical control of the same surgical services was used for comparison. INTERVENTION: None. MAIN OUTCOME MEASURES: Incidence of diarrhea and CDAD, use of bowel preparations, surgical procedure, use of C difficile toxin assay, white blood cell count, symptoms, treatment, and delay in hospital discharge. RESULTS: The incidence of diarrhea in surgery patients analyzed prospectively was 6.1%; the incidence of CDAD during the prospective and retrospective periods was 2%. Preoperative bowel preparations were associated with an increased risk of diarrhea (relative risk, 4.2; 95% confidence interval, 2.6-6.8; P < .001) and CDAD (relative risk, 3.2; 95% confidence interval, 1.5-7.2; P < .03). Leukocytosis (white blood cell count > 11 x 10(9)/L) was significantly higher in the CDAD group compared with the diarrhea group only on the day of diagnosis (P < .05). By subjective analysis, diarrhea was directly responsible for a delay in discharge in 7 of 29 patients for a mean (+/-SEM) of 4.0 +/- 1.0 days. CONCLUSIONS: Patients undergoing preoperative bowel preparations are at increased risk of experiencing diarrhea and CDAD. Among patients with diarrhea, an elevated white blood cell count may help identify those with C difficile. Early treatment of diarrhea with oral metronidazole while awaiting the results of the stool toxin assay is recommended for treating diarrhea in surgery patients. Prophylactic treatment of surgery patients undergoing bowel preparations should be considered.

Cost containment in cardiac surgery: results with a critical pathway for coronary bypass surgery at the New York hospital-Cornell Medical Center.

PURPOSE: A multidisciplinary project was undertaken at The New York Hospital-Cornell Medical Center to develop critical pathways for open-heart surgery to help reduce cost, shorten hospital length of stay (LOS), and streamline patient care. METHODS: A critical pathway for elective coronary artery bypass grafting instituted on March 1, 1995, was developed through a cooperative effort involving surgeons, anesthesiologists, nurses, social workers, physical therapists, nutritionists, and patient case managers. Prospective data collected on consecutive patients forming a critical pathway group (n = 114) over a 6-month period were compared with retrospective data on consecutive patients forming a cohort group (n = 382) who underwent elective coronary artery bypass grafting in 1994. RESULTS: The critical pathway group of patients experienced a significantly shorter total hospital LOS (7.7 +/- 2.3 days vs 11.1 +/- 6 days, p < 0.0001) and shorter intensive care unit LOS (1.5 +/- 0.9 days vs 2.0 +/- 2.8 days, p < 0.0001). Direct costs were computed by use of hospital charges multiplied by the Medicare cost-to-charge ratio. Mean hospital direct cost (ancillary resources) was $1181 lower in the critical pathway group when compared with the control group (p < 0.0001). The postoperative mortality and readmission rates were similar for the two groups of patients. CONCLUSIONS: The ongoing analysis of cost, LOSs, and outcomes has made possible a process of continuous quality improvement on the cardiothoracic service in which further areas for improvement are identified and studied. The use of a critical pathway for elective coronary artery bypass grafting at our institution significantly reduced hospital LOS and direct costs while maintaining the overall quality of patient care.
