To examine the impact of Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance (PROMIS-SD) on clinical outcomes in patients undergoing lumbar decompression. Patients undergoing lumbar decompression with preoperative PROMIS-SD scores were retrospectively included. Patients were separated into 2 cohorts: none to slight sleep disturbance (PROMIS-SD <55) and mild to severe sleep disturbance (PROMIS-SD ≥55). Patient-reported outcome measures including PROMIS Physical Function, PROMIS Anxiety, PROMIS Pain Interference, PROMIS SD, 9-item Patient Health Questionnaire, visual analog scale back/leg, and Oswestry Disability Index were collected preoperatively and up to 1 year postoperatively. Of 87 patients identified, 48 patients had PROMIS-SD scores ≥55. Regardless of preoperative PROMIS-SD score, patients reported significant improvement in physical function, anxiety, pain interference, depression, pain, and disability outcomes in at least 1 time point. Patients in the PROMIS-SD ≥55 cohort reported postoperative improvement in sleep disturbance. Patients in the PROMIS-SD <55 cohort reported superior preoperative patient-reported outcome measures in all domains and superior postoperative improvement in pain interference and sleep disturbance. Minimum clinically important difference attainment rates were higher in the PROMIS-SD ≥55 cohort in physical function, anxiety, pain interference, sleep disturbance, and pain. Patients undergoing lumbar decompression demonstrated significant postoperative improvement in most clinical outcomes regardless of preoperative sleep disturbance. Patients with mild to severe sleep disturbance had higher minimum clinically important difference attainment rates for physical function, mental function, and pain. Patients undergoing lumbar decompression with greater preoperative sleep disturbance may experience more clinically noticeable improvement. [ABSTRACT FROM AUTHOR]

To compare perioperative characteristics, patient-reported outcome measures (PROMs) and minimum clinically important difference (MCID) achievement after anterior cervical discectomy and fusion (ACDF) in patients stratified by preoperative neck disability. The Neck Disability Index (NDI) assesses a patient's self-perceived neck disability and is often used to assess the efficacy of cervical surgical intervention. Our study (a retrospective cohort study) evaluates how preoperative severity of patient neck disability influences postoperative clinical improvement after ACDF. Primary, single-level, or multilevel ACDF procedures were included. PROMs were administered at preoperative/6 week/12 week/6 month/1 year/2 year time points and included Patient-Reported Outcome Measurement Information System–Physical Function (PROMIS-PF), visual analog scale (VAS) for neck and arm pain, NDI, and 12-Item Short-Form (SF-12) Physical Composite Score (PCS). Patients were grouped according to preoperative NDI <50 (mild to moderate neck disability) or NDI ≥50 (severe neck disability). Demographics/perioperative characteristics/postoperative complications/mean PROMs/MCID achievement rates were compared using χ2 or Student t test. Postoperative improvement from preoperative baseline within each cohort was assessed with paired-samples t test. MCID achievement was determined by comparing ΔPROMs with established thresholds. A total of 225 patients were included, 150 NDI <50 and 75 NDI ≥50. The NDI ≥50 cohort was significantly younger (P = 0.002). Cohorts did not differ for spinal disease/operative duration/estimated blood loss/postoperative length of stay/postoperative narcotic consumption/adjacent segment disease rate/1-year arthrodesis rate/6-month pseudarthrosis rate. Postoperative VAS pain score on postoperative day 0 and 1 was significantly increased in the NDI ≥50 cohort (P < 0.048, all). Postoperative complication rates did not differ. All mean PROMs differed at all time points (P < 0.043, all). The NDI <50 patient cohort significantly improved from preoperative baseline for all PROMs and time points except SF-12 PCS/Patient-Reported Outcome Measurement Information System–Physical Function at 6 weeks. The NDI ≥50 cohort significantly improved for all PROMs and time points except SF-12 PCS at 6 weeks. The NDI ≥50 cohort showed a greater proportion achieving MCID for NDI at 6 weeks/2 years/overall (P < 0.037, all). Both cohorts showed significant long-term clinical improvement for neck pain/arm pain/physical function/neck disability, although patients with severe preoperative neck disability reported inferior mean scores for these outcomes at all time points.

To compare patient-reported outcomes (PROMs), satisfaction, and minimum clinically important difference (MCID) achievement following minimally invasive transforaminal lumbar interbody fusion stratified by preoperative disability. Minimally invasive transforaminal lumbar interbody fusions were grouped by preoperative Oswestry Disability Index (ODI) score: ODI <41 or ODI ≥41. PROMs administered pre/postoperatively included Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF), visual analog scale (VAS) back/leg, ODI, and 12-Item Short-Form Physical Composite Score (SF-12 PCS)/12-Item Short-Form Mental Composite Score (SF-12 MCS). Satisfaction scores were collected for VAS back/leg and ODI. Coarsened exact match controlled for differences between cohorts. T tests compared mean PROMs and postoperative improvement/satisfaction between cohorts. Simple logistic regression compared MCID achievement. After coarsened exact matching, there were 118 patients in the ODI ≤41 and 377 patients in the ODI >41 cohort. The ODI >41 cohort saw greater postoperative inpatient VAS pain score and narcotic consumption on days 0/1 (P < 0.018, all). PROMs differed between cohorts: PROMIS-PF, SF-12 PCS, ODI, VAS back/leg at all postoperative time points and SF-12 MCS at 6 weeks/12 weeks/6 months/1 year (P < 0.045, all). Patients in the ODI >41 cohort demonstrated greater proportion achieving MCID for ODI at all postoperative time points and for SF-12 MCS 6-week/12-week/6-month/1-year (P < 0.040, all). The ODI ≤41 cohort demonstrated greater MCID achievement for overall PROMIS-PF and SF-12 PCS 6 months (P < 0.047, all). Postoperative satisfaction was greater in the ODI ≤41 cohort for VAS leg 6 weeks/12 weeks, VAS back 6 weeks/12 weeks, and ODI all postoperative time points (P < 0.048, all). Preoperative disability associated with worse postoperative PROMs and patient satisfaction for disability, back/leg pain at multiple time points. MCID achievement rates across cohorts were similar for most PROMs at most postoperative time points. Patients with severe disability may have unrealistic expectations for surgical benefits, influencing corresponding postoperative satisfaction. [ABSTRACT FROM AUTHOR]
