Hospital readmission in stroke survivors one year versus three years after discharge from inpatient rehabilitation: Prevalence and associations in an Asian cohort.

The methods report 1,158 patients screened and 23 ineligible, while Table I lists n=1,235, so the analysed number is not fully clear. The study looked backward at records and did not assign treatments, so it cannot show what caused readmission. It was done at one Singapore rehabilitation centre, so it may not apply to other health systems. Family support and socioeconomic status were not available, so some risk may be unexplained. Some readmissions outside the regional hospital group may have been missed, though a local study found less than 6% incidence. Patients who died during the index admission or were discharged to palliative care were excluded, so the sickest patients are not represented.

Do not conclude that more rehabilitation caused fewer readmissions. The study linked greater FIM gain to lower readmission odds, but it did not randomise rehabilitation and cannot separate therapy effects from baseline function.
