A Data Quality Study of a Danish Hospital Discharge Registry [Elektronische Daten] Abstract Objective: To assess the data quality of septicemia and sepsis registration in a hospital discharge registry in the County of Northern Jutland, Denmark. Design: Comparison of data from the discharge registry of an 880-bed, public, urban hospital in the County of Northern Jutland with data from a computerized bac-teremia database at the regional department of clinical microbiology. Setting: Urban hospital with approximately 45,000 admissions per year. Patients: The study included 406 episodes of bac-teremia in the bacteremia database and 83 discharges with the diagnosis of septicemia registered in the hospital discharge registry between January 1, 1994, and December 31, 1994. Interventions: None. Results: Eighteen episodes were registered in both the hospital discharge registry and the bacteremia database. Using the bacteremia database as reference standard, the sensitivity for the diagnosis of septicemia in the hospital discharge registry was 4.4% (18/406; 95% confidence intervals [CI95, 2.4%-6.4%]). By review of hospital records, we estimated the positive predictive value of septicemia registration in the hospital discharge registry as 21.7% (18/83; CI95, 12.8%-30.5%). No blood culture had been obtained in 44.4% (36/81; CI95, 33.6%-55.3%) of the cases with a discharge diagnosis of septicemia. In 33.3% (27/81; CI95, 23.1%-43.6%), the discharge diagnosis of septicemia was given, although blood cultures were negative. Conclusions: The hospital discharge registry revealed numerous misclassifications, and the system was found not suited for surveillance of, or research in, bacteremia at present Copyright © The Society for Healthcare Epidemiology of America 1998 Madsen Kreesten Meldgaard Danish Epidemiology Science Centre at the Department of Epidemiology and Social Medicine, Aarhus University, Aarhus, Denmark Schønheyder Henrik Carl Department of Clinical Microbiology, Aalborg Hospital, Aalborg, Denmark Kristensen Brian Department of Clinical Microbiology, Aalborg Hospital, Aalborg, Denmark Nielsen Gunnar Lauge Danish Epidemiology Science Centre at the Department of Epidemiology and Social Medicine, Aarhus University, Aarhus, Denmark Sørensen Henrik Toft Danish Epidemiology Science Centre at the Department of Epidemiology and Social Medicine, Aarhus University, Aarhus, Denmark Infection Control & Hospital Epidemiology Cambridge University Press 19/3(1998-03) 0899-823X 19:3 1998 19 ICE https://doi.org/10.1086/647790 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1086/647790 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Madsen Kreesten Meldgaard Danish Epidemiology Science Centre at the Department of Epidemiology and Social Medicine, Aarhus University, Aarhus, Denmark NATIONALLICENCE 700 1- Schønheyder Henrik Carl Department of Clinical Microbiology, Aalborg Hospital, Aalborg, Denmark NATIONALLICENCE 700 1- Kristensen Brian Department of Clinical Microbiology, Aalborg Hospital, Aalborg, Denmark NATIONALLICENCE 700 1- Nielsen Gunnar Lauge Danish Epidemiology Science Centre at the Department of Epidemiology and Social Medicine, Aarhus University, Aarhus, Denmark NATIONALLICENCE 700 1- Sørensen Henrik Toft Danish Epidemiology Science Centre at the Department of Epidemiology and Social Medicine, Aarhus University, Aarhus, Denmark NATIONALLICENCE 773 0- Infection Control & Hospital Epidemiology Cambridge University Press 19/3(1998-03) 0899-823X 19:3 1998 19 ICE CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-cambridge
