The Impact of Text Messaging to Promote Patient Reported Outcome Measures (PROMs) Completion in Orthopedic Practice: Findings From a Randomized Controlled Study

Abstract

It is difficult to achieve high response rates to Patient Reported Outcome Measures (PROMs) surveys collected as part of clinical care. However, they are operationally and clinically important. To understand the impact of text message reminders on response rates to PROMs collected via email as part of routine care for hip or knee replacement surgery, initial nonresponders were randomized to receive a text reminder or not at 7 and 12 days, if needed. At day 7, the overall survey response rate was 63%. Model-derived estimates for survey return after this point were 51.1% (95% confidence interval [CI], 48.0%–54.2%) in the text arm compared to 34.5% (95% CI, 31.6%–37.6%) in the no text arm. The effect of text messages on response rates did not vary by subpopulations considered nor were there differences in rates of key outcomes between the 2 groups, suggesting that it did not impact any underlying response bias. Given the relative low cost of text messages, they can be an efficient means to increase response rates.
