Evaluation of Sleep Quality and Its Relationship With Pain, Mood, and Physical Function After Orthopaedic Trauma Surgery: A Prospective Cohort Study

Introduction:Sleep disturbances are associated with pain and mental health. We prospectively compared a cohort of patients with orthopaedic trauma with a control group to establish the prevalence and duration of sleep disturbance and associations between sleep disturbance and pain, mood scores, and functional outcome scores.Methods:Subjects were patients with orthopaedic trauma undergoing in-patient surgical procedures and healthy control subjects from the community. Questionnaires completed by all subjects included the VAS numerical pain rating scale, the abbreviated profile of mood states, Patient-Reported Outcomes Measurement Information System Physical Function, and Patient-Reported Outcomes Measurement Information System Sleep Disturbance. Control subjects completed the surveys once, and subjects with trauma completed them at 2, 6, and 24 weeks postoperatively.Results:Healthy control subjects (28.6 +/- 13.2) were significantly younger than patients with trauma (41.8 +/- 18.9) (P < 0.001). Compared with control subjects, at 2-week follow-up visit, patients with trauma had worse sleep (P < 0.001) and worse mood (P = 0.006). Across the study period, patients with trauma showed improvements in physical function (P < 0.001) and pain (at rest [P = 0.02], during activity [P = 0.02], and at night [P = 0.002]). In patients with trauma, better sleep disturbance scores were associated with better mood and less pain for all pain metrics (P < 0.001).Discussion:Patients with orthopaedic trauma have worse sleep disturbance scores at 2 weeks postoperatively compared with normal control subjects; this difference attenuated at 6 weeks. Sleep disturbance was found to markedly correlate with pain and mood, with worse sleep quality associated with higher pain and worse mood. Improvement in sleep quality across 24 weeks postoperatively was associated with improvement in mood scores.Conclusion:Patients should be counseled about the likely development of sleep disturbance and the possible association with worse emotional/mental health with worse sleep. Physicians should consider incorporating a multidisciplinary approach to the management of these select patients.
