Impact of Psychiatric Illness on Outcomes After Operatively Managed Tibial Plateau Fractures (OTA-41).

OBJECTIVES

To assess the role self-reported treatment for a psychiatric diagnosis may play in long-term functional outcomes after operatively managed tibial plateau fractures.

DESIGN

Prospective cohort study.

SETTING

Academic medical center.

PATIENTS

Over an 11-year period, patients were screened and identified on presentation to the emergency department or in the clinical office for inclusion in an IRB-approved registry. A total of 245 patients were included in the study. Twenty-one patients reported treatment for a psychiatric diagnosis.

INTERVENTION

Surgical repair of tibial plateau fractures.

MAIN OUTCOME MEASURE

Patients were divided into 2 cohorts; 1 cohort being those who self-reported receiving treatment of a psychiatric diagnosis (PI); the other group being those who did not self-report receiving treatment of a psychiatric diagnosis (NPI). Three-month, 6-month, and long-term outcomes (mean = 18 months) were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, and postoperative complications (infection, VTE, nonunion, and necessity for secondary operations).

RESULTS

Pain scores were higher in patients who self-reported receiving treatment for a psychiatric diagnosis (P = 0.012). Long-term functional outcomes as measured by the SFMA were demonstrated to be worse in patients who self-reported treatment for a psychiatric diagnosis (P = 0.034). No differences existed between groups in regards to postoperative complications. Multiple linear regression analysis revealed that being treated for diagnosis of a mental health illness was an independent predictor of worse functional outcomes at long-term follow-up [B = 8.874, 95% confidence interval (CI) = 0.354-17.394, P = 0.041].

CONCLUSIONS

Mental health plays a crucial role in long-term outcomes after operative fixation of tibial plateau fractures. Patients who have been diagnosed with a mental health illness have significantly worse outcomes at long-term follow-up.
