Knee osteoarthritis (OA) is a common chronic disease that leads to knee pain, stiffness and limited physical function. A multi-faceted treatment composed of medication management, exercise, health education, and weight control is identified as effective for the reduction of knee pain and increased physical function. This quasi-experimental study undertaken in rural Thailand had an interrupted time-series design and examined whether a multi-faceted intervention delivered by nurse practitioners resulted in improved health status regarding knee OA symptom, quality of life and satisfaction with nursing care and reduced medication usage compared to standard treatment. There were 108 participants (58 experimental, 58 control) who completed the study. The multi-faceted intervention included education, group exercise, weight loss, and medication management delivered over aI2-week period. Four time points were used across the study (weeks 1 and 4 pre-intervention and 16 and 20 post-intervention) to collect data including the Western Ontario and McMaster Universities Arthritis Index (WOMAC), Self-Form 36 (SF-36), Leeds Satisfaction Questionnaires (LSQ) and medication usage diary. Analysis of variance and non-parametric analyses were used to examine differences across time and t-tests and mean change differences were used to examine the group differences pre- and post- intervention. The experimental group reported significant mean change increase in LSQ score and a mean change decrease in medication usage than the control group post-intervention. This supported the hypotheses that the multi-faceted intervention delivered by nurse practitioners would result in greater satisfaction with nursing care and a reduction in medication usage than standard treatment among patients with knee OA. There were no significant mean change differences in the WOMAC and SF-36 scores between the groups. However, both groups reported improvement in WOMAC and SF-36 scores so it is probable that both treatments helped to maintain health status and quality of life.
