Continuous Variable Predictive Modeling of Length of Hospital Stay (LOS) Following Adult Spinal Deformity (ASD) Correction: Analysis of 653 Patients with an Accuracy of 75% Within 2 Days

57 Background: Palliative radiation therapy (PRT) offers effective symptomatic relief to cancer patients. Increased focus on quality of care and healthcare efficiency necessitate a better understanding of the temporal relationships between consultation for/initiation of PRT and length of hospital stay (LOS). This study aims to assess whether durations from admission to PRT consult/PRT initiation affect LOS. Methods: In an institutional review of patients who received PRT as inpatients between January 2017 and December 2018, 67 met inclusion criteria. Duration of time from admission to consultation or start of PRT were categorized using various thresholds. LOS was compared across groups using the Wilcoxon rank sum test and factors were evaluated as predictors of LOS using bivariate linear regression. Results: PRT was given for pain (37%), neurologic deficits/brain metastases (31%), and respiratory symptoms (19%). Multiple sites were treated in 31%; treatment sites included spine (45%), non-spine bone (27%), chest (22%), abdomen/pelvis (12%), brain (10%) and soft tissue (6%). At admission, patients had known metastases (66%), no prior cancer diagnosis (19%), or known primary cancer (15%). Median LOS was 12 days (IQR 7-18) for all patients. There was a significant difference in LOS for patients referred for PRT within 3 days of admission versus greater than 3 days (11 v. 21 days, p < 0.01). This difference was slightly greater using a threshold of 4 days (11 v. 25 days, p < 0.01) and 5 days (11 v. 26 days, p < 0.01), both of which remained significant when analyzing only patients with prior cancer diagnosis (n = 54). There was no difference in LOS using a threshold of 1 or 2 days. As a continuous variable, duration from admission to PRT was associated with LOS (OR 2.40, p < 0.01). Similar patterns were noted when analyzing by time from admission to PRT start. Conclusions: Earlier radiation oncology consultation for PRT is associated with shorter LOS in patients treated with PRT for symptomatic malignancy. Further research is needed to better define this relationship and improve systematic processes to facilitate early consultation and treatment. A palliative radiation oncology clinic was recently developed to address these issues at our institution.

Abstract Study Design: Retrospective case series.Objectives: This study aimed to determine the prevalence and risk factors for orthostatic hypotension (OH) in adolescents undergoing posterior spinal fusion for spinal deformity correction.Methods: The data of 312 consecutive adolescents who underwent posterior spinal fusion for spinal deformity correction in our center over 12 months were retrieved. Patient characteristics, including whether laminectomy or osteotomy was performed during the surgery, the occurrence of postoperative nausea and vomiting (PONV), perioperative hemoglobin albumin changes, perioperative blood transfusion, length of bed rest, willingness to ambulate, length of postoperative exercises of the lower limbs, and length of hospital stay, were collected and compared statistically between patients who did and did not develop postoperative OH.Results: Of 312 patients, 225 (72.1%) developed OH postoperatively, and all cases completely resolved 5 days after the first out-of-bed exercises. Significant differences in BMI, the incidence of PONV, the willingness to ambulate and the length of postoperative exercises of the lower limbs were observed. The mean length of hospital stay of the patients with OH was longer than that of the patients without OH.Conclusion: Our study suggests that temporary OH is a common manifestation following posterior spinal fusion for spinal deformity correction in adolescents. Postoperative OH may increase the length of hospital stay in these patients. Patients with PONV, who are not willing to ambulate and who perform postoperative lower limb exercises for a shorter time are more likely to have OH.

OBJECTIVEMany options exist for the surgical management of adult spinal deformity. Radiculopathy and lumbosacral pain from the fractional curve (FC), typically from L4 to S1, is frequently a reason for scoliosis patients to pursue surgical intervention. The purpose of this study was to evaluate the outcomes of limited fusion of the FC only versus treatment of the entire deformity with long fusions.METHODSAll adult scoliosis patients treated at the authors’ institution in the period from 2006 to 2016 were retrospectively analyzed. Patients with FCs from L4 to S1 > 10° and radiculopathy ipsilateral to the concavity of the FC were eligible for study inclusion and had undergone three categories of surgery: 1) FC only (FC group), 2) lower thoracic to sacrum (LT group), or 3) upper thoracic to sacrum (UT group). Primary outcomes were the rates of revision surgery and complications. Secondary outcomes were estimated blood loss, length of hospital stay, and discharge destination. Spinopelvic parameters were measured, and patients were stratified accordingly.RESULTSOf the 99 patients eligible for inclusion in the study, 27 were in the FC group, 46 in the LT group, and 26 in the UT group. There were no significant preoperative differences in age, sex, smoking status, prior operation, FC magnitude, pelvic tilt (PT), sagittal vertical axis (SVA), coronal balance, pelvic incidence–lumbar lordosis (PI-LL) mismatch, or proportion of well-aligned spines (SVA < 5 cm, PI-LL mismatch < 10°, and PT < 20°) among the three treatment groups. Mean follow-up was 30 (range 12–112) months, with a minimum 1-year follow-up. The FC group had a lower medical complication rate (22% [FC] vs 57% [LT] vs 58% [UT], p = 0.009) but a higher rate of extension surgery (26% [FC] vs 13% [LT] vs 4% [UT], p = 0.068). The respective average estimated blood loss (592 vs 1950 vs 2634 ml, p < 0.001), length of hospital stay (5.5 vs 8.3 vs 8.3 days, p < 0.001), and rate of discharge to acute rehabilitation (30% vs 46% vs 85%, p < 0.001) were all lower for FC and highest for UT.CONCLUSIONSTreatment of the FC only is associated with a lower complication rate, shorter hospital stay, and less blood loss than complete scoliosis treatment. However, there is a higher associated rate of extension of the construct to the lower or upper thoracic levels, and patients should be counseled when considering their options.
