Clinical Prediction Rules of Tanaka et al for a Decline in ADL at 6 Months After Hip Fracture Surgery: Model Based on Prerehabilitation Data

Description

Tanaka et al reported clinical decision rules for disability at 6 months after a hip fracture. One model was based on prerehabilitation data only. The authors are from Hiroshima International University, Saiseikaikure Hospital and Chugokurosai Hospital in Japan.

Patient selection: hip fracture (proximal femur)

Outcome: activities of daily living (ADL) at 6 months after repair

Model: CART (classification and regression tree)

Parameters:

(1) age of the patient in years

(2) type of femoral fracture

(3) nursing care level prior to the fracture (none, support level 1, support level 2, care level 1, care level 2, care level 3, care level 4, care level 5)

Age	Fracture Type	Nursing Care	Worse ADL at 6 months
< 81 years	NA	NA	12.8%
81 to 87.9	femoral neck	NA	69.2%
>= 88 years	femoral neck	NA	23.1%
>= 81	trochanteric or subtrochanteric	none	42.9%
>= 81	trochanteric or subtrochanteric	needed support level 1 or higher	85.7%
