ObjectiveTo evaluate impact of preoperative mental health on expectations in patients undergoing transforaminal, anterior, or lateral lumbar interbody fusion.MethodsDemographics, perioperative characteristics, duration of preoperative symptoms, and preoperative mental health scores were collected. Pain and disability were recorded using preoperative visual analog scale (VAS) for back and leg pain and Oswestry Disability Index scores. Patients' expectations were recorded. Preoperative mental health was recorded using Patient Health Questionnaire-9 (PHQ-9), 12-Item Short Form Health Survey (SF-12) mental component score (MCS), and Veterans RAND 12-Item Health Survey (VR-12) MCS. PHQ-9 scores were categorized by severity of depressive symptoms. Simple linear regression evaluated impact of preoperative mental health on patient expectations for pain and disability; multiple linear regression evaluated the same while accounting for preoperative scores.ResultsIn 181 patients, PHQ-9 and increasing severity of depressive symptoms significantly predicted VAS back pain expectations (P ≤ 0.006); significance was lost after accounting for preoperative VAS back pain. All mental health outcomes significantly predicted VAS leg pain expectations (P ≤ 0.040); only PHQ-9 retained significance after accounting for preoperative VAS leg pain. All mental health scores significantly predicted ODI expectations (P < 0.001); none retained significance after accounting for preoperative ODI. PHQ-9, SF-12, and VR-12 significantly predicted all ODI domains except personal care and pain intensity (P ≤ 0.045). PHQ-9 significantly predicted patient expectations for lifting, walking, standing, sleeping, sex life, and social life. SF-12 MCS significantly predicted expectations for lifting, walking, standing, sleeping, and social life after accounting for preoperative domain scores. VR-12 MCS significantly predicted expectations for lifting, walking, standing, sleeping, sex life, and social life (P ≤0.050, all), even after accounting for preoperative scores.ConclusionsMental health scores impact expectations regarding improvement in more active areas of a patient's life. Poor mental health scores may be associated with lower expectations for preoperative symptom improvement.Published by Elsevier Inc.
