Health-related quality of life after total hip replacement: a Taiwan study

This study applied the generalised estimating equations (GEE) in a large-scale prospective cohort study of predictors of health-related quality of life (HRQoL) in a Taiwan population. The study population included all patients who had undergone primary total hip replacement (THR) performed between March 1998 and December 2002 by either of two orthopaedic surgeons in two hospitals. The SF-36 was used in pre- and postoperative assessments of 335 patients. Young age, male gender, minimal comorbidity, use of epidural anaesthesia, lack of readmission within the previous 30 days, and higher preoperative functional status were positively associated with HRQoL (P < 0.05). Patients should be advised that their postoperative HRQoL may depend not only on their postoperative health care but also on their preoperative functional status. These analytical results should be applicable to other Taiwan hospitals and to other countries with similar social and cultural practices.RésuméCette étude a pour but d’estimer la qualité de vie (HRQoL) de la population Taiwanaise après PTH. Méthode: la population étudiée a inclus tous les patients ayant bénéficié d’une prothèse totale de hanche primaire (THR) réalisée entre mars 1998 et décembre 2002 par deux chirurgiens orthopédistes dans deux établissements hospitaliers différents. Le questionnaire SF-36 a été utilisé en pré et postopératoire sur 335 patients. Résultats: jeune âge, sexe masculin, comorbidités minimes, utilisation de l’anesthésie épidurale et absence de réhospitalisation dans les 30 jours sont corrélés de façon positive avec le score HRQoL (P < 0.05). Conclusion: les patients sont avertis que le score HRQoL postopératoire dépend non seulement de leur état de santé postopératoire mais également de leur statut fonctionnel préopératoire. Cette analyse peut être généralisée à d’autres établissements hospitaliers Taïwanais et à d’autres pays présentant des similitudes sur le plan social et culturel.
