Published online in the journal Neurology, a new study sheds light on the effectiveness of tools used to predict recovery after stroke.
Lead author of the study, Dr Terry Quinn, explains the research:
"There are lots of different scales developed that are said to predict how well someone will recover from their stroke. These scales can help clinicians make difficult decisions around interventions such as thrombolysis and thrombectomy. The use of these scales is recommended in guidelines but no particular scale is named as the preferred one. All the scales were developed in isolation and there has never been a head-to-head comparison to see which is best – until now.
"We used a dataset of several thousand patients and compared the prognostic (predictive) power of the scales. There were clear differences between the scales, and some scales seem to work better than others for predicting who will recover well and who will not make a good recovery. However, arguably, none of the scales were ‘good enough’ to be used as the sole factor in determining the treatment a person with stroke should receive."
