Total hospital stay for hip fracture: measuring the variations due to pre-fracture residence, rehabilitation, complications and comorbidities

Table 2 Unadjusted mean values for components of total LOS for hip fracture

	Community patients		RAC patients		All patients
Phase	N	Mean LOS (days)	N	Mean LOS (days)	N	Mean LOS (days)
All admissions
Acute	1844	14.1	708	11.6	2552	13.4
Rehabilitation	1050	25.1*	122	21.3	1172	24.8
Other	519	24.9*	133	18.6	652	23.6
Combined phases	1844	35.4*	708	18.8	2552	30.8
Admissions which include rehabilitation
Acute	1050	11.8	122	10.9	1172	11.7
Rehabilitation	1050	25.1	122	21.3	172	24.8
Other	272	20.8	37	16.3	309	20.2
Combined phases	1050	42.3	122	37.2	1172	41.7
Admissions without rehabilitation
Acute	794	17.0	586	11.8	1380	14.8
Other	247	29.5	96	19.4	343	26.7
Combined phases	794	26.2	586	14.9	1380	21.4

*Mean LOS for combined phases (total LOS) = weighted average from each component. For community patients = ((1844 × 14.1) + 1050 × 25.1) + (519 × 24.9))/1844 = 35.4 days.
