Comparison of mortality rates for open and closed cholecystectomy in the elderly: Connecticut statewide survey.

The objective was to determine the safety of laparoscopic cholecystectomy for patients 65 years of age and older with symptomatic uncomplicated chronic gallbladder disease by comparing the mortality rate with open cholecystectomy. Connecticut Hospital Information Management Exchange and the Connecticut Society of American Board of Surgeons established a Connecticut Laparoscopic Registry made up of 33 acute care hospitals. A cohort longitudinal retrospective statewide registry collected data mortality rates on all 2865 elderly patients undergoing open (OC) or closed (LC) cholecystectomy for uncomplicated chronic cholecystitis. A database was established and continuously monitored from October 1, 1988, to December 31, 1992. Seven hundred sixty-one patients over 65 years of age underwent open cholecystectomy for uncomplicated chronic cholecystectomy during fiscal year 1989, with a mortality rate of 1.4%. The mortality rate of a similar cohort of patients who underwent laparoscopic cholecystectomy during fiscal years 1991 and 1992 was 0.3% and 0.6%, respectively. The mortality rate was further broken down into age subsets 65-69, 70-79, and 80+. The prelaparoscopic era (FY 1989) age subsets were compared with those of the laparoscopic era (FY 1991 and 1992). A statistically significant reduction (p = 0.01) in mortality rate was noted in the 70-79 age group following laparoscopic surgery. Laparoscopic cholecystectomy in the elderly for the treatment of symptomatic, uncomplicated chronic cholecystitis is as safe if not safer than open cholecystectomy as measured by mortality rate.

The "Toward Excellence in Care" program: a statewide indicator project.

BACKGROUND: The "Toward Excellence in Care" program was launched by Connecticut hospitals and physicians in 1988 to develop and use quality-of-care indicators for use in quality improvement. METHODOLOGY: Data came primarily from the Connecticut Health Information Management and Exchange (CHIME) database, which contains discharge abstract information, UB (uniform billing)-82 information, and additional data elements, for all of Connecticut's 34 acute care hospitals. Linkages also occur with the state mortality database, the trauma registry, and with admission/discharge data within and across Connecticut hospitals. The "Toward Excellence in Care" program staff help the hospital use the data on indicator reports for quality improvement. EXAMPLE: On receiving a report on care for patients with acute myocardial infarction (AMI) a program representative summarized opportunities for improvement. The data were then disseminated to both the cardiology and the hospitalwide quality improvement staffs. Cardiologists conducted chart review on 100% of patients included in the last time-frame on the report (for example, fiscal year 1991). The quality improvement professional documented the system of care for an AMI patient. Recommended actions included adoption of a policy for emergency department administration of thrombolytic therapy before a cardiology consultation, and modification of the postcoronary care program. CONCLUSIONS: Progress in addressing four challenges-easing the burden of data collection on the hospitals, maximizing acceptance of information by hospitals and physicians, risk adjusting data to permit comparison of outcomes, and facilitating understanding of reports--is reflected in expanding use of the "Toward Excellence in Care" program.

Changes in Connecticut hospital use rates: have small-area variations been affected?

This paper examines the extent to which changes (prospective payment, alternative delivery systems, etc.) in the hospital environment and the general decline in hospital days affect small-area variations in hospital use rates for 18 selected diagnoses in nine hospital service areas in Connecticut. After adjusting for coding changes between DRGs, we found that variation across the service areas did not, in general, differ for any one of the years 1981-86. In one instance (cardiac catheterization), however, we found that a DRG-specific change in knowledge and technology decreased the extent of small-area variation for that diagnosis.

Analysis of Variance

The National WIC Evaluation: evaluation of the Special Supplemental Food Program for Women, Infants, and Children. IV. Study methodology and sample characteristics in the longitudinal study of pregnant women, the study of children, and the food expenditures study.

The longitudinal study of pregnant women enrolled a national probability sample of 5,205 women first certified for WIC and 1,358 comparable low-income pregnant women in 174 WIC clinics located in 58 areas in the contiguous 48 states and in 55 prenatal clinics without WIC programs in counties with low program coverage. The women completed 24-h dietary recalls, histories of food expenditures, health care utilization, health and sociodemographic status, and anthropometric assessment. At late-pregnancy follow-up 3,967 WIC and 1043 control women were interviewed and 853 WIC and 762 control women completed 1-wk food expenditure diaries. Birth outcome was abstracted (from hospital records) for 3,863 WIC and 1058 control women. Anthropometry, dietary intake, health, and use of health services were related to WIC among 2,619 random low-income preschoolers. Psychological development was assessed in 526 children aged 4 and 5 y. Control women had higher income, education, and employment status; therefore, WIC program benefits probably were underestimated.

Diagnosis

Verification of information in a large medical database using linkages with external databases.

Efforts to utilize Uniform Hospital Discharge Data Sets (UHDDS) for epidemiological studies have been hampered by the limitations of those databases. The purpose of this paper is to illustrate that linking to external databases can provide the verification necessary to overcome many of those limitations. This method has dramatically altered study design at the Connecticut Hospital Research and Education Foundation and has provided an efficient method for specifying data collection weaknesses within the resident databases.
