Orthopedic nursing; Hospitals--Admission and discharge--Data processing


The objective of this study was to determine the association between scores on the Large Allen Cognitive Levels Screen (LACLS) and the Mini-Mental Statue Examination (MMSE) among residents of a skilled nursing facility (SNF) and to what extent they have predictive validity for discharge disposition. Data were collected from one SNF in Washington State through a retrospective chart review. Among all cases, no correlations were found between the MMSE and discharge disposition, and the LACLS and discharge disposition. However, the LACLS was a statistically significant predictor of discharge disposition among orthopedic patients, r (22) = .479, p = .01. A statistically significant correlation was found between the LACLS and MMSE, r (122) = .565, p = .01 in all cases, and for 28% of the population, the assessments were not in agreement of cognitive status. The difference between mean scores of patients who discharged to supported versus unsupported living on the MMSE (21.45 vs. 21.83) and LACLS (4.31 vs. 4.21) were insignificant, indicating these assessments may not be valid as sole predictors of discharge disposition. Complex medical and social histories of the elderly population are among many factors that affect where and why a patient is discharged to a particular location. Further research is needed to provide stronger evidence for the MMSE and LACLS in their predictive validity for discharge disposition.
