Comprehensive geriatric assessment for older adults admitted to ...

Cohen 2002 (Continued)
Outcomes Outcomes: death, perceived health status, basic and extended ADL, costs
Trial conclusions: no overall effects on survival. Improved physical function with inpatient
care, improved cognitive function with outpatient care
Notes This trial was subdivided into 4 groups in a 2 x 2 factorial design. It explored the
hypothesis that CGA out-patient follow up was associated with a significantly improved
outcome.
The first subgroup of the trial evaluated Geriatric Evaluation and Management Clinic
(GEMC) follow up post-discharge from inpatient care. This splitting of the data has
been done to enable meta-analysis for the outpatient follow up subgroup.
The second subgroup of the trial evaluated Usual Care Outpatient (UCOP) follow up
following discharge from inpatient care
Risk of bias
Bias Authors’ judgement Support for judgement
Random sequence generation (selection
bias)
Low risk Computerised random numbers in two-bytwo
factorial design with stratification according
to functional status
Allocation concealment (selection bias) Low risk Randomisation remote at co-ordinating
centre
Blinding (performance bias and detection
bias)
All outcomes
Incomplete outcome data (attrition bias)
All outcomes
Low risk Blinding of outcome assessor only
Low risk Intention-to-treat analysis
Selective reporting (reporting bias) Unclear risk No a priori documentation could be found
to judge this item
Other bias Low risk No evidence to suggest selection, performance
or attrition bias
Baseline outcome measurements similar Low risk Identical baseline assessments
Baseline characteristics similar Low risk Similar baseline characteristics
Study protected against contamination Low risk Care conducted on different units with different
groups of staff
