Predicting nonroutine discharge in patients undergoing surgery for vertebral column tumors

OBJECTIVEMore than 8000 patients are treated annually for vertebral column tumors, of whom roughly two-thirds will be discharged to an inpatient facility (nonroutine discharge). Nonroutine discharge is associated with increased care costs as well as delays in discharge and poorer patient outcomes. In this study, the authors sought to develop a prediction model of nonroutine discharge in the population of vertebral column tumor patients.METHODSPatients treated for primary or metastatic vertebral column tumors at a single comprehensive cancer center were identified for inclusion. Data were gathered regarding surgical procedure, patient demographics, insurance status, and medical comorbidities. Frailty was assessed using the modified 5-item Frailty Index (mFI-5) and medical complexity was assessed using the modified Charlson Comorbidity Index (mCCI). Multivariable logistic regression was used to identify independent predictors of nonroutine discharge, and multivariable linear regression was used to identify predictors of prolonged length of stay (LOS). The discharge model was internally validated using 1000 bootstrapped samples.RESULTSThe authors identified 350 patients (mean age 57.0 ± 13.6 years, 53.1% male, and 67.1% treated for metastatic vs primary disease). Significant predictors of prolonged LOS included higher mCCI score (β = 0.74; p = 0.026), higher serum absolute neutrophil count (β = 0.35; p = 0.001), lower hematocrit (β = −0.34; p = 0.001), use of a staged operation (β = 4.99; p < 0.001), occurrence of postoperative pulmonary embolism (β = 3.93; p = 0.004), and surgical site infection (β = 9.93; p < 0.001). Significant predictors of nonroutine discharge included emergency admission (OR 3.09; p = 0.001), higher mFI-5 score (OR 1.90; p = 0.001), lower serum albumin level (OR 0.43 per g/dL; p < 0.001), and operations with multiple stages (OR 4.10; p < 0.001). The resulting statistical model was deployed as a web-based calculator (https://jhuspine4.shinyapps.io/Nonroutine_Discharge_Tumor/).CONCLUSIONSThe authors found that nonroutine discharge of patients with surgically treated vertebral column tumors was predicted by emergency admission, increased frailty, lower serum albumin level, and staged surgical procedures. The resulting web-based calculator tool may be useful clinically to aid in discharge planning for spinal oncology patients by preoperatively identifying patients likely to require placement in an inpatient facility postoperatively.

Abstract Abstract 4001 Background: Low serum albumin level is known to be an adverse prognostic factor in patients with malignancies such as multiple myeloma. We previously reported that severe hypoalbuminemia (<3.0 g/dl) at day +90 post allogeneic hematopoietic stem cell transplant (AHCT) was an independent predictor of non-relapse and overall mortality in patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) (Kharfan-Dabaja et al Biol Blood Marrow Transplant. 2010 Jul). In this study we examined prognostic value of serum albumin level in patients with MDS. Methods: Data were analyzed from the Moffitt Cancer Center (MCC) MDS database with chart review verification. The primary objective was to examine the role of serum albumin at time of presentation to MCC as a prognostic marker for overall survival (OS). Patients were divided into 3 groups of serum albumin levels (≤ 3.5, 3.6–4.0 and > 4.0 g/dl). The Kaplan–Meier method was used to estimate median OS. The log rank test was used to compare Kaplan–Meier survival estimates between two groups. Cox proportional hazards regression was used for multivariable analysis. Results: Between January 2001 and December 2009, 844 patients were captured by the MCC MDS database. The median age was 69 years. MDS subtypes were coded as refractory anemia (RA) (n=98;12%), refractory anemia with ring sideroblasts (RARS) (n=76;9%), del(5q) (n=20;2.4%), refractory cytopenia with multi-lineage dysplasia (RCMD) (n=96;11%), refractory anemia with excess blasts (RAEB) (n=255;30%), therapy related MDS (n=22;2.6%), and MDS-NOS (n=275; 33%). The distribution of IPSS risk groups was: 18.7% Low risk, 42.9% Intermediate-1 (Int-1), 19.9% Int-2, 5.3% High risk, and 13.2% unknown. Baseline characteristics for the three patient groups defined by serum albumin level are summarized in (Table-1). There was no difference in red blood cell transfusion dependency (RBC-TD) rate between the 3 groups (p=0.21). The median OS for all patients was 36 months (95% confidence interval (CI) 31.5–40.5 mo). Age, IPSS risk group, RBC-TD, Serum ferritin were statistically significant prognostic factors in univariable analysis. The median OS was 19 mo (95%CI= 14.9–23.1 mo), 35 mo (95%CI= 28.7–41.3 mo), and 53 mo (95%CI= 44.7–61.3 mo) for patients with serum albumin levels ≤ 3.5 g/dl, 3.6–4.0 g/dl, > 4.0 g/dl, respectively. (Figure-1) (p= <0.005). After adjustment for age, RBC-TD, OS was statistically significantly inferior among MDS patients with lower serum albumin (Hazard Ratio (HR) = 0.79.; 95%CI= 0.69–0.90; p= 0.001), and higher-risk IPSS group (HR=1.67; 95%CI=1.48-1.87; p= <0.005). The overall rate of AML transformation was 29.2%. Rate of AML transformation was higher in patients with lower serum albumin, 38% in patients with serum albumin ≤ 3.5 g/dl, 30% for patients 3.6–4.0 g/dl, and 23% in patients with serum albumin > 4.0 g/dl (p-value 0.005). Among patients in the Low/Int-1 IPSS risk group, the median OS was 28 mo (95%CI=15.7-40.3 mo), 48 mo (95%CI=38.8-58.0 mo), and 60 mo (95%CI=47.6-72.4 mo) for patients with serum albumin levels ≤ 3.5 g/dl, 3.6–4.0 g/dl and > 4.0 g/dl, respectively (p=0.003). Among patients in the Int-2/High IPSS risk group, the median OS was 16 mo (95%CI 13.3–15.7 mo), 22 mo (95%CI 18.0–26.0 mo), and 21 mo (95%CI 8.8–33.2 mo) respectively for patients with serum albumin levels ≤ 3.5 g/dl, 3.6–4.0 g/dl and > 4.0 g/dl, respectively p=0.03). Conclusion: In this retrospective analysis of a large single institution MDS database, serum albumin is found to be an independent prognostic factor for OS and AML transformation in MDS patients. The prognostic power of low serum albumin was greatest among patients with Low/Int-1 IPSS risk group, but remained an independent variable across all risk groups. Serum albumin may also be a surrogate marker of general health, co- morbidities, and performance status. Disclosures: No relevant conflicts of interest to declare.

ObjectivesTo investigate the risk factors associated with early-onset peritonitis (EOP) and their influence on patients’ technique survival and mortality.Study designRetrospective, cohort study.SettingThree peritoneal dialysis (PD) units in Shanghai.ParticipantsPD patients from 1 June 2006 to 1 May 2018 were recruited and followed up until 31 December 2018. According to time-to-first episode of peritonitis, patients were divided into non-peritonitis (n=144), EOP (≤6 months, n=74) and late-onset peritonitis (LOP) (>6 months, n=139).Primary and secondary outcome measuresEOP was defined as the first episode of peritonitis occurring within 6 months after the initiation of PD. The outcomes were all-cause mortality and technique failure.ResultsOf the 357 patients, 74 (20.7%) patients developed their first episode of peritonitis within the first 6 months. Compared with the LOP group, the EOP group had older ages, more female patients, higher Charlson Comorbidity Index (CCI) score, lower serum albumin levels and renal function at the time of initiation of PD, and higher diabetes mellitus and peritonitis rates (p<0.05).Staphylococcuswas the most common Gram-positive organism in both EOP and LOP groups. The multivariate logistic regression analysis showed that factors associated with EOP included a higher CCI score (OR 1.285, p=0.011), lower serum albumin level (OR 0.924, p=0.016) and lower Kt/V (OR 0.600, p=0.018) at start of PD. In the Cox proportional-hazards model, EOP was more likely a predictor of technique failure (HR 1.801, p=0.051). There was no difference between EOP and LOP for all-cause mortality.ConclusionA higher CCI score and lower serum albumin level and Kt/V at PD initiation were significantly associated with EOP. EOP also predicted a high peritonitis rate and poor clinical outcome.
