Insights
Developing accurate pediatric mortality prognostication models using administrative data is feasible. These models can help compare healthcare services for critically ill children, improving end-of-life care quality.
Area of Science:
- Pediatric Health Services Research
- Biostatistics
- Health Outcomes
Background:
- Assessing pediatric end-of-life care quality is challenging due to a lack of methods to adjust for mortality risk in ill children.
- Accurate prognostication is crucial for comparing healthcare delivery and financing systems.
Purpose of the Study:
- To develop and validate prognostication models using readily available administrative data.
- Predict the probability of in-hospital and 1-year postdischarge death in pediatric patients.
Main Methods:
- Retrospective cohort study of 678,365 pediatric patients (0-21 years) admitted to Pennsylvania hospitals (1994-2001).
- Logistic regression models were used to predict in-hospital and 1-year postdischarge mortality.
- Model performance was assessed using C statistics, sensitivity, and specificity.
Main Results:
- The model for in-hospital deaths achieved a C statistic of 0.91 (sensitivity 65.9%, specificity 92.9%).
- The model for 1-year postdischarge deaths achieved a C statistic of 0.92 (sensitivity 56.1%, specificity 98.4%).
- Low mortality rates were observed: 0.32% in-hospital and 0.13% within 1 year postdischarge.
Conclusions:
- Population-level mortality prognostication for hospitalized children is feasible using administrative data.
- These models can aid in comparing healthcare services for children at high risk of death.
- The findings support the use of administrative data for quality assessment in pediatric healthcare.
Background:
The study of how the quality of pediatric end-of-life care varies across systems of health care delivery and financing is hampered by lack of methods to adjust for the probability of death in populations of ill children.
Objective:
To develop a prognostication models using administratively available data to predict the probability of in-hospital and 1-year postdischarge death.
Methods:
Retrospective cohort study of 0-21 year old patients admitted to Pennsylvania hospitals from 1994-2001 and followed for 1-year postdischarge mortality, assessing logistic regression models ability to predict in-hospital and 1-year postdischarge deaths.
Results:
Among 678,365 subjects there were 2,202 deaths that occurred during the hospitalization (0.32% of cohort) and 860 deaths that occurred 365 days or less after hospital discharge (0.13% of cohort). The model predicting hospitalization deaths exhibited a C statistic of 0.91, with sensitivity of 65.9% and specificity of 92.9% at the 99th percentile cutpoint; while the model predicting 1-year postdischarge deaths exhibited a C statistic of 0.92, with sensitivity of 56.1% and specificity of 98.4% at the 99th percentile cutpoint.
Conclusions:
Population-level mortality prognostication of hospitalized children using administratively available data is feasible, assisting the comparison of health care services delivered to children with the highest probability of dying during and after a hospital admission.
