Insights
Death certificates inadequately capture nosocomial infections, missing most cases. Improved physician training is crucial for accurate data collection on hospital-acquired infections.
Area of Science:
- Medical Informatics
- Epidemiology
- Public Health Surveillance
Context:
- Hospital-acquired infections (HAIs) pose a significant threat to patient safety.
- Accurate data collection on HAIs is essential for effective infection control and prevention strategies.
- Current methods for reporting HAIs, such as death certificates, may be insufficient.
Purpose:
- To assess the utility of death certificates as a data source for nosocomial infections.
- To compare the accuracy of information on original death certificates with data from medical charts.
- To determine the prevalence of nosocomial infections identified through revised death certificates.
Summary:
- Medical charts of pediatric patients who died in-hospital were reviewed alongside their death certificates.
- Death certificates showed a 69.9% agreement with medical records regarding causes of death.
- Only 1% of nosocomial infections were noted on original death certificates, compared to 88.9% on redrafted certificates.
Impact:
- Death certificates are unreliable for tracking nosocomial infections due to inadequate completion.
- Enhanced physician education is recommended for accurate identification and documentation of HAIs.
- Improved data quality can lead to better understanding and control of hospital-acquired infections.
Objective:
The purpose of this study was to evaluate the possibility for collecting data on nosocomial infections by means of death certificates.
Methods:
The medical charts of children who died after 48 hours of their admission to a pediatric hospital were revised to get information about the causes of death. Death certificates were also revised to verify whether they were properly filled out. The death certificates were redrafted according to the data obtained from patients' medical charts. Nosocomial infections and procedures related to them were codified using the Supplementary External Causes of Injury and Poisoning codes of the International Disease Classification-9th Revision.
Results:
The causes mentioned on medical death certificates compared with revised causes obtained after revision of patients' charts showed an agreement of 69.9%, with a Kappa coefficient of 0.65. Only one case of nosocomial infection was found on original death certificates, whereas the redrafted certificates revealed 88.9% of nosocomial infections in the study population up to fifteen days before death.
Conclusion:
Death certificates are not a good source of information on nosocomial infection because they are often filled out inadequately. The solution to this is to qualify physicians so that they can identify and record nosocomial infections on the patient's medical chart and complete death certificates accordingly.
