OBJECTIVE: To systematically summarize the literature on: (i) the course of pain
and physical functioning; and (ii) predictors of deterioration of pain and
physical functioning in patients with osteoarthritis of the hip. METHODS: A
literature search was conducted in PubMed, CINAHL, Embase, PsychINFO and
SPORTDiscus up to July 2015. Meta-analyses and qualitative data syntheses were
performed. RESULTS: Eleven of the 15 included studies were of high quality. With
regard to the course of pain and physical functioning, high heterogeneity was
found across studies (I2 > 71%) and within study populations (reflected by large
standard deviations (SDs) of change scores). Therefore, the course of pain and
physical functioning was interpreted to be indistinct. Clinical characteristics
(higher comorbidity count and presence of knee osteoarthritis), health behaviour
factors (no supervised exercise and physical inactivity) and socio-demographics
(lower education) were found to predict deterioration of pain (weak evidence).
Higher comorbidity count and lower vitality were found to predict deterioration
of physical functioning (strong evidence). For several other predictive factors
weak evidence was found (e.g. bilateral hip pain, increase in hip pain (change),
bilateral knee pain, presence of knee osteoarthritis). CONCLUSION: Because of
high heterogeneity across studies and within study populations, no conclusions
can be drawn with regard to the course of pain and physical functioning. Several
clinical characteristics, health behaviours and psychosocial factors
prognosticate deterioration of pain and physical functioning. These findings may
guide future research aimed at the identification of subgroups of patients with
hip osteoarthritis.
