0788 Sleep Profile of Adolescents Following Posterior Spinal Fusion

Abstract

Abstract Introduction Major musculoskeletal operations can have a prolonged impact on patients’ quality of life during the postoperative period. Sleep patterns can be affected by general anesthesia, complex and prolonged operations, and post-surgical care. Sleep disturbance can be considered a determinant of poor postsurgical outcomes. In this study, we examined the sleep profile of adolescents who underwent Posterior Spine Fusion (PSF) utilizing the FitBit Charge 4TM wearable device. Methods Patients were approached at the time of their evaluation in the orthopedic office once they had been scheduled for PSF. Patients received a Fitbit Charge 4TM at the time of enrollment. Total sleep time (TST), the duration of REM and Deep Sleep phases, and sleep efficiency were obtained from patients’ FitBit4 data and were calculated by averaging data recorded over a 2-4-day period during the week prior to surgery, during the hospital stay, one-two-three weeks, and 3 months after patients were discharged home. Patients were given a PROMIS sleep questionnaire delivered to their cellular phone using Qualtrics the week before the hospitalization, during hospitalization, and 3 months after surgery. Pain scores were obtained every 4-6 hours during the patient’s hospital stay using the self-reporting numeric scale. Results 16 patients (10 female (62%)) completed the 3 months study period. Mean age was 16±1.9 years. The average length of hospitalization was 3 days. The average TST, REM, and DEEP sleep at baseline was 387±111, 74±28, 75±25 minutes respectively. TST, REM, and DEEP sleep decreased during the acute post-operative period and gradually increased during the follow-up period going to baseline values by the 3rd post-surgery week in 72% of the cases. Perception of sleep showed mild disturbance at baseline and worsened during the hospital stay based on PROMIS scores with improvement or return to baseline by the 3rd month post-operatively in 86% of patients. Conclusion Sleep phases of adolescents are affected after a major surgery. Similar to patients of other major surgeries, these changes are short-lived and returned to baseline by the 3rd post-operative week. There was a broad range of changes among subjects during the study period. Support (if any)
