PG - 1923-1929 LID - 10.1007/s00701-023-05593-8 [doi] AB - PURPOSE: Patients with preoperative depressive symptoms may demonstrate inferior patient-reported outcomes (PROs). The effect of preoperative symptom duration (SD) on PROs in this population has not been well-studied. We aim to assess the influence of preoperative SD on PROs in patients with low mental health scores prior to minimally invasive transforaminal interbody fusion (MIS-TLIF). METHODS: Patients who had undergone elective, primary MIS-TLIF with preoperative SF-12 MCS score below 45.6, a previously established threshold for depression, were selected. Patients were divided into matched lesser duration (LD; SD<365 days) and greater duration (GD; SD>/=365 days) cohorts. PROs were collected preoperatively and at 6-week/12-week/6-month/1-year postoperative periods. PROs included PROMIS-PF/ODI/VAS back/VAS leg/SF-12 MCS. PROs were compared within and between groups. Rates of achievement of minimal clinically important difference (MCID) were compared between groups. RESULTS: One hundred twenty-two patients were included after matching cohorts. Patients in the LD cohort demonstrated improvement in PROMIS-PF at 12-weeks/6-month/1-year, and ODI/VAS back/VAS leg/SF-12 MCS at all postoperative periods (p
