The determinants of successful in-hospital rehabilitation in people aged 90 years and older.
OBJECTIVE
The very elderly constitute a subgroup of elderly who may respond differently than the younger elderly to medical intervention. This possibility has not previously been investigated. Our study investigates whether successful rehabilitation of the very elderly is possible within the current processes of care and also whether factors that help predict successful rehabilitation in all age elderly are applicable to the oldest old.


METHODS
A retrospective case note analysis of all very elderly people (>or=90 years old) treated within in-patient elderly person rehabilitation facilities at the Northern General Hospital, Sheffield. Potential predictive factors analysed: Barthel index, main presenting illness, number of co-morbid conditions, number of regular prescribed medications, abbreviated mental test score, prior formal social services input, previous hospital admission within 1 year and serum albumin (g/l). Outcome measures reflecting success of rehabilitation: duration of rehabilitation (days), discharge destination to the same ('good outcome') or increased ('poor outcome') level of social and/or nursing care, readmission to hospital within 30 days of discharge and death during rehabilitation or within 120 days of discharge.


RESULTS
Of 230 nonagenarians admitted to inpatient elderly rehabilitation 47% required no increase in social support following their admission and 76% of those admitted from their own home were able to return there. Barthel index and the number of co-morbid conditions were the most influential predictors of success, with Barthel index predicting length of stay (p < 0.001), discharge destination (p < 0.001) and in-hospital mortality (p < 0.01) and co-morbidity predicting readmission to hospital (p = 0.05), in-hospital mortality (p = 0.04) and survival (p = 0.05). On multi-variate analysis all other predictive factors analysed, except for presenting illness, were associated with at least one outcome measure (p < 0.05).


CONCLUSIONS
Successful inpatient rehabilitation of the very elderly is possible. Factors that predict the success of rehabilitation of nonagenarians are similar to those associated with success in the younger elderly. The factors that most broadly predict success are Barthel index and the number of co-morbid conditions identified at admission to rehabilitation. Main presenting illness did not emerge as a predictor within this group.
