- ItemElectronic data capture using the Womac NRS 3.1 Index (m-Womac): a pilot study of repeated independent remote data capture in OA.(2010-05-21) Bellamy, Nicholas; Patel, B; Davis, T; Dennison, SAIM A preliminary evaluation of mobile phone technology for repeated independent remote data capture using the mobile phone based m WOMAC NRS 3 1 Index METHODS Following orientation to the m WOMAC Index and initial completion in the office patients took the phones home and independently completed the Index on four subsequent occasions over 12 days sending their data each time to a server in USA RESULTS Three men and nine women with hip n 2 and knee n 10 OA successfully completed the m WOMAC Index on each occasion Average time to completing the Index at termination was 4 8 min The majority of patients rated logging on opening the application completing the m WOMAC Index on the phone and sending data as very easy 10 11 12 and were very confident 11 12 in continuing to use the phone to report their symptoms CONCLUSIONS These data support the feasibility of repeated independent remote data capture using the m WOMAC NRS3 1 Index
- ItemOsteoarthritis Index delivered by mobile phone (m-WOMAC) is valid, reliable, and responsive.(2010-12-21) Bellamy, Nicholas; Wilson, Cecilia; Hendrikz, Joan; Whitehouse, Sarah L; Patel, Bipin; Dennison, Simon; Davis, Tim; ,OBJECTIVES To evaluate the validity reliability responsiveness and mode preference of electronic data capture EDC using the Western Ontario and McMaster WOMAC numerical rating scale NRS 3 1 Osteoarthritis OA Index on Motorola V3 mobile phones STUDY DESIGN AND SETTING Patients with OA undergoing hip or knee joint replacement were assessed preoperatively and 3 4 months postoperatively completing the WOMAC Index in paper p WOMAC and electronic m WOMAC format in random order RESULTS Data were successfully and securely transmitted from patients in Australia to a server in the United States Pearson correlations between the summated total index scores TISs for the p WOMAC and m WOMAC pre and postsurgery were 0 98 and 0 99 PUnder0 0001 There were no clinically important or statistically significant between method differences in the adjusted total summated scores pre and postsurgery adjusted mean differences 4 44 P 0 474 and 1 73 P 0 781 respectively Internal consistency estimates of m WOMAC reliability were 0 87 0 98 The m WOMAC detected clinically important statistically significant PUnder0 0001 improvements in pain stiffness function and TIS No statistically significant differences in mode preference were detected CONCLUSIONS There was close agreement and no significant differences between m WOMAC and p WOMAC scores This study confirms the validity reliability and responsiveness of the Exco InTouch engineered Java based m WOMAC Index application EDC with the m WOMAC Index provides unique opportunities for using quantitative measurement in clinical research and practice
