Is the patient outcomes of surgery (POS)-Hand/Arm questionnaire a reliable, valid and responsive measurement of patient-based outcomes in hand and upper limb surgery?

摘要

The purpose of our study was to evaluate a new region-specific outcome measure in hand and upper limb surgery: the Patient Outcomes of Surgery (POS)-Hand/Arm questionnaire using the generic Short Form Health Survey (SF)-36 questionnaire as a 'gold standard' comparative measure. The POS-Hand/Arm preop questionnaire and the SF-36 questionnaire were completed by 214 patients on the day of their hand or upper limb surgery; and a postop POS-Hand/Arm and the SF-36 questionnaire were completed by patients 3 months after their initial surgery. The POS-Hand/ Arm questionnaire responses were psychometrically evaluated and it was shown to have high internal consistency; high total-item correlations; signification scale correlations with the SF-36; and a low proportion of missing data. The POS-Hand/Arm questionnaire is a psychometrically sound instrument that can be used pre- and post-surgery to evaluate patient-based outcomes for a wide range of conditions in hand and upper limb surgery.
