Nine studies (n=2,013) were included: 3 RCTs (n=732), 2 quasi-randomised controlled studies (n= 277), 3 historical cohort studies (n=990) and 1 case-control study (n=14).
Out of a possible 9 points for quality, 3 studies scored 9, one scored 8, three scored 5, one scored 4 and one scored 3.
Four trials showed a statistically significant reduction in LOS associated with additional OBH physiotherapy. Studies reported significant reductions in LOS in patients undergoing elective joint arthroplasty, patients with pelvis/spine trauma and non-surgical neurological patients.
There were no significant decreases in hospital stay for patients with ankle/foot trauma, or stroke, rheumatology or cardiac patients. The overall WMD for LOS was -0.15 days (95% CI: -0.37, 0.07).
Pulmonary complications. Two studies reported a statistically significant reduction in pulmonary complications for patients in an intensive care unit.
Discharge destination and/or discharge mobility status.
Three studies considered the effect on discharge destination and/or discharge mobility status and found no significant difference.
