Effect of varying the time frame for COOP-WONCA functional health status charts : a nested randomised controlled trial in Bristol, UK.
Study objective-To investigate whether changing the stated time frame for COOP-WONCA charts has any effect on responses.
Specifically, to assess the effect of attempting to avoid the situation where the time frame crosses the onset of an acute episode.
Design-A randomised controlled trial of two time frames, nested within a main trial comparing early discharge with a hospital at home scheme against routine discharge policy.
The time frames compared were the standard two weeks (four for the pain chart) and a shorter period of 48 hours for all seven charts.
Setting-Acute hospital wards in Frenchay Healthcare Trust and the Avon Orthopaedic Centre in Bristol.
Participants-Patients entered into the main trial, who were medically stable, in need of continued rehabilitative care but suitable for discharge to hospital at home.
Main results-A total of 200 patients were randomised, 106 to the shorter time frame, 94 to the standard charts.
No clear differences were observed between the two groups for the proportion failing to self complete the charts.
For the (seven) chart scores, only pain was statistically significantly different between the time frames (Mann-Whitney p=0.0085 ; proportion reporting moderate or severe pain 19% higher in the standard group, 95% confidence intervals 5% to 33%). (...)
