Initiation of a novel text messaging system in total knee and hip arthroplasty.

Background: The primary objective of this study was to investigate whether using a novel text messaging system improves patient overall satisfaction compared to standard care. Secondary objectives included assessing the impact of the text messaging system on decreasing narcotic usage, the number of emergency department visits, the range of flexion and extension, and number of telephone calls to the surgeon's office.

Methods: We enrolled 217 patients to either receive informative text messages (text messaging group, n = 86) or no additional text messages (conventional group, n = 131). Patients self-reported results on a questionnaire at the 6-week follow-up regarding the primary and secondary objectives. The active range of motion of total knee arthroplasty patients was recorded by the surgeon or treating physiotherapist.

Results: There was no significant difference in overall satisfaction (P = 0.644), narcotic cessation (P = 0.185), range of motion (Flexion P = 0.521; Extension P = 0.515), and emergency department visits (P = 0.650) between the two groups. There was a statistically significant decrease in surgeon office calls favoring the text messaging group (P = 0.029). A subgroup analysis revealed that the statistical difference was mainly in the TKA group (P = 0.046).

Conclusions: A novel text messaging system may help reduce the work burden by decreasing telephone calls to the surgeon's office. While satisfaction, narcotic usage, emergency department visits, and range of motion did not significantly differ, patients endorsed the system for friends/family.
