INTRODUCTION: It is not always possible to use a combination of patient-reported
outcome measures (PROMs), performance tests and clinician-administrated measures
to assess physical function prior to hip surgery. We hypothesised that there
would be low correlations between these three types of measure and that they
would be associated with different patients' characteristics.
METHODS: We conducted a cross-sectional analysis of the preoperative information
of 125 participants listed for hip replacement. The WOMAC-function subscale,
Harris Hip Score (HHS) and walk, step and balance tests were assessed by
questionnaire or during a clinic visit. Participant's socio-demographics and
medical characteristics were also collected. Correlations between functional
measures were investigated with correlation coefficients. Regression models were
used to test the association between the patient's characteristics and each of
the three types of functional measures. RESULTS: None of the correlations between
the PROM, clinician-administrated measure and performance tests were very high
(<0.90). Associations between patient's characteristics and functional scores
varied by type of measure. Psychological status was associated with the PROM
(P-value<0.0001) but not with the other measures. Age was associated with the
performance test measures (P-value ranging from </=0.01 to <0.0001) but not with
the PROM. The clinician-administered measure was not associated with age or
psychological status. DISCUSSION: Substantial discrepancies exist when assessing
hip function using a PROM, functional test or a clinician-administered test.
Moreover, these assessment methods are influenced differently by patient's
characteristics. Clinicians should supplement their pre-surgery assessment of
function with patient-reported measure to include the patient's perspective.
