Health-related quality of life assessments in osteoarthritis during NSAID treatment.
There is some evidence that nabumetone (1000 mg once daily) in comparison with piroxicam (20 mg once daily) in patients with OA in general practice is associated with a lower incidence and less severe occurrence of stomach pain but with more withdrawals due to lack of efficacy. The aim of this analysis was to investigate whether these differences are reflected in health-related quality of life assessments. Patients (n = 198) included in this study were selected in general practice according to a protocol. The patients were randomized and treated for a period of six weeks. Clinical assessments were performed by the general practitioner (CP) during treatment. The Sickness Impact Profile (SIP), the Activities of Daily Living (ADL), and a pain questionnaire were filled out by the patients before and after treatment. As measured with the SIP, the ADL and the pain questionnaire, there were no significant differences between nabumetone and piroxicam. The correlations between (changes in) patient assessments and (changes in) clinical assessments were low. The differences between the two drugs regarding withdrawals and adverse events were not reflected by patient health-related quality of life assessments. There was a low correlation between patient health-related quality of life assessment and clinical assessments. To get a complete picture of the efficacy and safety of a drug, patient health-related quality of life assessments should be a part of a clinical trial.
