Background: The "I COUGH" protocol is associated with improved postoperative pulmonary outcomes, and ambulation is an essential component. I COUGH is an acronym for Incentive spirometry, Coughing, Oral care, Understanding (patient and staff education), Getting-out-of-bed, and Head-of-bed elevation. This trial sought to enhance one component, specifically ambulation after operations.
Methods: Randomized trial of inpatients in a safety-net, academic medical center. The intervention group received standard I COUGH education along with text message reminders to ambulate postoperatively, whereas the control group received standard education alone. Postoperative walking frequency was compared to each participant's ambulation on the day prior to enrollment.
Results: The intervention group had an average improvement of 1.8 ± 1.8 walks per day per patient, while the average change for the control group was 0.2 ± 1.0 walks per day per patient. This represents a 9-fold increase in ambulation for the intervention group (p = 0.03).
Conclusions: Implementation of text message reminders increased ambulation and improved adherence to the I COUGH protocol following operations. This system should be further investigated as an adjunct to postoperative care.
