Background The Obstetric Quality of Recovery-10 is a patient-reported outcome measure designed to evaluate early global postpartum recovery. No Polish version exists, and most prior validations excluded women with high-risk pregnancies. Methods In this prospective single-center cohort study at a tertiary referral center for placenta accreta spectrum, the Polish translation was administered at 24, 48 and 72 h postpartum. The primary aim was a psychometric evaluation at 24 h (structural validity, convergent validity against the EuroQol five-dimension index and visual analogue scale, internal consistency, test-retest reliability, floor and ceiling effects). The secondary aim was to explore univariable associations with obstetric and anesthetic variables. Results Of 800 eligible women approached, 441 consented, with data from 410 analyzed. Internal consistency (Cronbach's alpha 0.90), test-retest reliability (intraclass correlation coefficient 0.85) and convergent validity (r = 0.77 and 0.69) were good, and a modified one-factor model fitted acceptably. At 24 h, 1.5% of women had a maximum score. Scores at 24 h were higher after vaginal compared with cesarean delivery (77.8 vs. 67.0; P < 0.001), higher after spinal compared with general anesthesia for cesarean delivery (68.6 vs. 51.0; P = 0.011), lower with increasing perineal injury severity (53.0 vs. 81.5; P = 0.001) and with placental pathologies (60.7 vs. 72.6; P = 0.003), and lowest in placenta accreta spectrum (42.4; n = 5). Discussion The Polish Obstetric Quality of Recovery-10 is reliable and demonstrated known-groups validity across the obstetric risk categories represented in this cohort. Associations in high-risk subgroups were unadjusted and require confirmation.
