A preliminary evaluation of mobile phone technology for repeated independent remote data capture using the mobile phone-based m-WOMAC® NRS 3.1 Index.
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.
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.
These data support the feasibility of repeated independent remote data capture using the m-WOMAC® NRS3.1 Index.
