Effectiveness of ERCP in cholangitis: a community-based study.

BACKGROUND: Although experts have demonstrated the efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in cholangitis, the effectiveness of ERCP in unselected patients has not been measured. The aim was to investigate the clinical impact of ERCP performed at any time and of early ERCP (within 24 hours of admission) in patients with a primary discharge diagnosis of cholangitis. METHODS: A retrospective record review of patients admitted to eight area hospitals with an International Classification of Diseases (ICD)-9 diagnosis consistent with cholangitis was performed. Extracted data included clinical characteristics, ERCP findings, and patient outcome. The associations of ERCP overall and early ERCP with length of stay were examined. Confounding factors including severity of illness, etiology of cholangitis, and hospital type were adjusted for in a multivariate analysis. RESULTS: A total of 116 patients were studied. ERCP was performed in 71 patients with endoscopic therapy administered in 57 (80%). ERCP overall was not associated with any change in length of hospital stay. However, compared with other invasive biliary procedures, ERCP was associated with a shorter hospital stay (median 5 vs. 9.5 days, p = 0.01) and a 36% (95% CI [5%, 57%]) reduction in severity-adjusted length of stay. Patients who had early ERCP had a significantly shorter hospital stay than those who had delayed ERCP (median 4 vs. 7 days, p < 0.005) and early ERCP was associated with a 34% (95% CI [11%, 48%]) reduction in severity-adjusted length of stay. CONCLUSION: Early ERCP may be an effective strategy for shortening the length of stay in patients hospitalized with cholangitis.

Early endoscopy in upper gastrointestinal hemorrhage: associations with recurrent bleeding, surgery, and length of hospital stay.

BACKGROUND: The impact of upper endoscopy in patients with upper gastrointestinal hemorrhage treated in community practice is unknown. Thus we examined the effectiveness of endoscopy performed within 24 hours of admission (early endoscopy). METHODS: Medical records of 909 consecutive hospitalized patients with upper gastrointestinal hemorrhage who underwent endoscopy at 13 hospitals in a large metropolitan area were reviewed. We evaluated unadjusted and severity-adjusted associations of early endoscopy with recurrent bleeding or surgery to control hemorrhage, length of hospital stay, and associations of endoscopic therapy in patients with bleeding ulcers or varices. RESULTS: Early endoscopy was performed in 64% of patients and compared with delayed endoscopy and was associated with clinically significant reductions in adjusted risk of recurrent bleeding or surgery (odds ratio [OR] 0.70: 95% CI [0.44, 1.13]) and a 31% decrease in adjusted length of stay (95% CI: [24%, 37%]). In patients at high risk for recurrent bleeding, the use of early endoscopic therapy to control hemorrhage was associated with reductions in recurrent bleeding or surgery (OR 0.21: 95% CI [0.10, 0.47]) and length of stay (-31%: 95% CI [-44%, -14%). CONCLUSION: In this study of community-based practice, the routine use of endoscopy, and in selected cases endoscopic therapy, performed early in the clinical course of patients with upper gastrointestinal hemorrhage was associated with reductions in length of stay and, possibly, the risk of recurrent bleeding and surgery.

Endoscopic practice for upper gastrointestinal hemorrhage: differences between major teaching and community-based hospitals.

BACKGROUND: Differences in endoscopic practice in major teaching and community hospitals are not known. METHODS: A total of 1031 consecutive patients discharged from 13 hospitals (4 major teaching, 9 others) in 1994 with upper gastrointestinal hemorrhage were studied. Data obtained from chart abstraction included endoscopic findings and therapy and selected outcomes. Multivariable analyses adjusted for admission severity of illness and endoscopic findings. RESULTS: Rates of endoscopy were similar between patients admitted to major teaching and other hospitals, although procedures to control hemorrhage were used more often in major teaching hospitals (35% vs. 19%, p < 0.001). Use of endoscopic therapy was higher in major teaching hospitals for lesions in which therapy is recommended, as well as other lesions. Recurrent bleeding was also more common in major teaching hospitals (14.3% vs. 7.8%, p = 0.001), and the difference persisted in multivariable analysis (odds ratio 1.69: 95% CI [1.09 to 2.64], p = 0.02). Unadjusted and adjusted length of stay were somewhat shorter in major teaching hospitals. CONCLUSIONS: There was large variation in the use of endoscopic therapy, with higher rates observed in major teaching hospitals for lesions in which therapy is recommended, as well as other stigmata. Further studies are needed to better define the reasons for the practice variation and to assess the impact on other outcomes such as readmission and costs.

Using hospital performance data in quality improvement: the Cleveland Health Quality Choice experience.

BACKGROUND: Cleveland Health Quality Choice is a regional initiative to assess hospital performance which was implemented in 1989. The project developed and validated CHOICE, a severity adjustment system that includes diagnosis-specific models for medical, surgical, and obstetrical patients which are based on clinical data abstracted from patients' medical records. METHODOLOGY: Since 1992 Cleveland Health Quality Choice has disseminated semi-annual reports that profile hospital mortality rates, lengths of stay, and cesarean section rates using the CHOICE severity adjustment models. Hospitals receive tabular and graphical representations of hospital outcomes and electronic patient-level data files that can be used to further examine outcomes in clinical subgroups. RESULTS: Four case studies illustrate how outcomes data derived from the CHOICE models led to the development of successful hospital programs to decrease lengths of stay, cesarean section rates, and hospital mortality rates. Although each case study reflected a unique approach to process improvement, several common characteristics were observed: (1) establishment of interdisciplinary process improvement teams with senior physician and nursing leadership; (2) detailed review of the process of care to identify modifiable clinical practices likely to affect outcomes; (3) development of practice guidelines based on group consensus or published recommendations that were designed to affect modifiable practices; and (4) aggressive sharing of serial data with individual practitioners. CONCLUSIONS: Although outcomes data can provide powerful insight on where to target quality improvement efforts, hospitals must identify influential and modifiable clinical practices. Such efforts are most likely to be successful if driven by interdisciplinary work groups, supported by senior clinicians and administrators, and based on locally accepted practice standards.

The Cleveland Health Quality Choice Program: an evaluation of quality.

The Cleveland Health Quality Choice Program, since early in its inception, has taken advantage of the unique relationship between the purchasers of health care and the providers. Regardless of the outcome of this endeavor, a collaboration has been established between the two and among the medical community involved in this program--a collaboration that the Cleveland community hopes to maintain in the future. Picture it...the business and medical communities sitting down at one table and coming to a consensus on various issues...quite an accomplishment in itself.
