Objective:
To develop an artificial neural network (ANN) designed to predict discharge destination from postacute geriatric rehabilitation units.
Design:
Nonconcurrent prospective study.
Setting:
Postacute geriatric rehabilitation units: a 20-bed unit in a nonproprietary skilled nursing facility and a 40-bed unit in a suburban private facility.
Patients:
Consecutive sample of 661 patients admitted between January 1995 and February 1999, including a derivation group of 452 patients and a validation group of 209 patients.
Interventions:
A feed-forward, back-propagation neural network to predict discharge destination.
Main Outcome Measure:
Discharge destination from postacute geriatric rehabilitation.
Results:
An ANN was trained on clinical pattern set derived from 452 patients and validated prospectively on 209 consecutive patients admitted to postacute geriatric rehabilitation units. The neural network achieved a sensitivity of 85.7% (95% confidence interval [CI], 83.7-89.4) and specificity of 94.1% (95% CI, 84.4-99.1) in identifying discharge destination with a corresponding area under the curve of 95.7% (95% CI, 92.1-98.3).
Conclusion:
An ANN can predict discharge to the community postacute rehabilitation with a high degree of accuracy. It could have particular value to predict return to the community for older adults with multiple comorbidities after an acute hospitalization.
