Interruptions to amputee rehabilitation

To determine the frequency of interruptions to inpatient amputee rehabilitation, and to identify the causes, risk factors, and consequences of these interruptions.

Retrospective cohort study.

Inpatient amputee rehabilitation service.

A total of 254 consecutive patients admitted within 90 days of amputation.

Not applicable.

Patient age, gender, comorbid medical conditions, amputation type(s), days from amputation to admission, admission Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) score, rehabilitation length of stay (LOS), whether a prosthesis was fabricated, discharge destination, discharge Houghton Scale score, discharge 2-minute walk test, and discharge SF-36 score.

Interruptions occurred in 76 patients (30%). Impaired stump healing caused 46 (18%) interruptions and acute medical illness caused 26 (10%); 4 (2%) interruptions were because of other causes. Higher incidence of interruption was associated with female gender, peripheral vascular disease, and decreased days from amputation to rehabilitation. The majority of patients with interruptions (60/76, 79%) returned to complete rehabilitation. Patients with interruptions had significantly longer rehabilitation LOS (48.5 vs 37.0d, P<.001), but functional outcome measures at rehabilitation discharge were similar between those patients who returned to complete rehabilitation after interruption and those patients without interruption.

Interruptions to amputee rehabilitation are common and result in longer rehabilitation LOS but do not adversely affect rehabilitation outcomes in those who are able to return to complete rehabilitation. No subgroup of patients with exceptionally high incidence of interruption could be identified.
