A Novel Preoperative Risk Score to Identify Patients at High Risk for Non-Home Discharge After Elective Open Abdominal Aortic Aneurysm Repair.

BACKGROUND: Non-home discharge (NHD) to a rehabilitation or skilled nursing facility after vascular surgery is poorly described despite its impact on patients. For home-dwelling patients undergoing elective surgery, the need for postoperative NHD can have meaningful implications on quality of life, long-term outcomes, and healthcare spending. Understanding post-surgical NHD risk is essential to preoperative counseling and shared decision making. This is particularly true for the treatment of abdominal aortic aneurysms as the postoperative course can vary between open and endovascular surgery. We aimed to identify independent predictors of NHD following elective open abdominal aortic aneurysm repair (OAR), and to create a clinically useful preoperative risk score. METHODS: Elective OAR cases were queried from the SVS Vascular Quality Initiative from years 2013-2022. A risk score was created by splitting the data set into two-thirds for development and one-third for validation. A parsimonious stepwise hierarchical multivariable logistic regression controlling for hospital level variation was performed in the development dataset, and the beta-coefficients were used to assign points for a risk score. The score was then validated, and model performance assessed. RESULTS: Overall, 8,274 patients were included and 1,502 (18.2%) required NHD. At baseline, patients who required NHD were more likely to be ≥ 80 years old (23.6% vs. 6.5%), female (35.9% vs. 23.1%), not independently ambulatory (14.6% vs. 4.3%), anemic (24.4% vs. 13.9%), have COPD (41.6% vs. 30.7%), ASA class ≥ 4 (41.0% vs. 32.5%), and a supraceliac proximal clamp (9.8% vs. 5.7%; all P<0.05). Multivariable analysis in the development group identified the following independent predictors of NHD: age ≥ 80 years, not independently ambulatory, proximal clamp location, hypogastric artery occlusion, anemia (Hb <12 g/dL), chronic obstructive pulmonary disease, female sex, hypertension, and American Society of Anesthesiologists class ≥ 4. These were then used to create a 14-point risk score. Patients were stratified into three groups based upon their risk score: low risk (0-4 points; n=4,966) with an NHD rate of 9.9%, moderate risk (5-6 points; n=2,442) with an NHD rate of 25.5%, and high risk (≥ 7 points; n=886) with an NHD rate of 44.6%. The risk score had good predictive ability with c-statistic=0.73 for model development and c-statistic=0.72 in the validation dataset. CONCLUSIONS: This novel risk score can predict NHD following elective OAR using characteristics that can be identified preoperatively. Utilization of this score may allow for improved risk assessment, preoperative counseling, and shared decision making.

Depression Is Associated With Non-Home Discharge After Coronary Artery Bypass Graft.

INTRODUCTION: Depression is disproportionately high in patients with coronary artery disease and has been associated with adverse outcomes following coronary artery bypass graft (CABG). One quality metric, non-home discharge (NHD), can have substantial implications for patients and health care resource utilization. Depression increases the risk of NHD after many operations, but it has not been studied after CABG. We hypothesized that a history of depression would be associated with an increased risk of NHD following CABG. METHODS: CABG cases were identified from the 2018 National Inpatient Sample using ICD-10 codes. Depression, demographic data, comorbidities, length of stay (LOS), rate of NHD were analyzed using appropriate statistical tests where a P-value < 0.05 was defined as statistically significant. Adjusted multivariable logistic regression models were used to assess independent association between depression and NHD as well as LOS while controlling for confounders. RESULTS: There were 31,309 patients, of which 2743 (8.8%) had depression. Depressed patients were younger, females, in a lower income quartile, and more medically complex. They also demonstrated more frequent NHD and prolonged LOS. After adjusted multivariable analysis, depressed patients had a 70% increased odds of NHD (adjusted odds ratio: 1.70 [1.52-1.89] P < 0.001) and a 24% increased odds of prolonged LOS (AOR: 1.24 [1.12-1.38] P < 0.001). CONCLUSIONS: From a national sample, depressed patients were associated with more frequent NHD following CABG. To our knowledge, this is the first study to demonstrate this, and it highlights the need for improved preoperative identification in order to improve risk stratification and timely allocation of discharge services.

The effects of sugammadex vs. neostigmine on postoperative respiratory complications and advanced healthcare utilisation: a multicentre retrospective cohort study.

Reversing neuromuscular blockade with sugammadex can eliminate residual paralysis, which has been associated with postoperative respiratory complications. There are equivocal data on whether sugammadex reduces these when compared with neostigmine. We investigated the association of the choice of reversal drug with postoperative respiratory complications and advanced healthcare utilisation. We included adult patients who underwent surgery and received general anaesthesia with sugammadex or neostigmine reversal at two academic healthcare networks between January 2016 and June 2021. The primary outcome was postoperative respiratory complications, defined as post-extubation oxygen saturation < 90%, respiratory failure requiring non-invasive ventilation, or tracheal re-intubation within 7 days. Our main secondary outcome was advanced healthcare utilisation, a composite outcome including: 7-day unplanned intensive care unit admission; 30-day hospital readmission; or non-home discharge. In total, 5746 (6.9%) of 83,250 included patients experienced postoperative respiratory complications. This was not associated with the reversal drug (adjusted OR (95%CI) 1.01 (0.94-1.08); p = 0.76). After excluding patients admitted from skilled nursing facilities, 8372 (10.5%) patients required advanced healthcare utilisation, which was not associated with the choice of reversal (adjusted OR (95%CI) 0.95 (0.89-1.01); p = 0.11). Equivalence testing supported an equivalent effect size of sugammadex and neostigmine on both outcomes, and neostigmine was non-inferior to sugammadex with regard to postoperative respiratory complications or advanced healthcare utilisation. Finally, there was no association between the reversal drug and major adverse cardiovascular events (adjusted OR 1.07 (0.94-1.21); p = 0.32). Compared with neostigmine, reversal of neuromuscular blockade with sugammadex was not associated with a reduction in postoperative respiratory complications or post-procedural advanced healthcare utilisation.

Outcomes of Prolonged ICU Stay for Patients Undergoing Cardiac Surgery in Australia and New Zealand.

OBJECTIVE: To determine the effect of intensive care unit (ICU) length of stay (LOS) on hospital mortality and non-home discharge for patients undergoing cardiac surgery over a 16-year period in Australia and New Zealand. DESIGN: A retrospective, multicenter cohort study covering the period January 1, 2004 to December 31, 2019. SETTING: One hundred one hospitals in Australia and New Zealand that submitted data to the Australia New Zealand Intensive Care Society Adult Patient Database. PARTICIPANTS: Adult patients (aged >18) who underwent coronary artery bypass grafting, valve surgery, or combined valve + coronary artery surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The authors analyzed 252,948 cardiac surgical patients from 101 hospitals, with a median age of 68.3 years (IQR 60-75.5), of whom 74.2% (187,632 of 252,948) were male patients. A U-shaped relationship was observed between ICU LOS and hospital mortality, with significantly elevated mortality at short (<20 hours) and long (>5 days) ICU LOS, which persisted after adjustment for illness severity and across clinically important subgroups (odds ratio for mortality with ICU LOS >5 days = 3.21, 95% CI 2.88-3.58, p < 0.001). CONCLUSIONS: Prolonged duration of ICU LOS after cardiac surgery is associated with increased hospital mortality in a U-shaped relationship. An ICU LOS >5 days should be considered a meaningful definition for prolonged ICU stay after cardiac surgery.

Operative Duration and Short-Term Postoperative Complications after Unicompartmental Knee Arthroplasty.

BACKGROUND: Prolonged operative duration is an independent risk factor for postoperative complications in many orthopedic procedures ranging from shoulder arthroscopy to total hip and knee arthroplasties. It has not been well studied in unicompartmental knee arthroplasty (UKA). The purpose of this study is to assess the effect of operative duration on complications after UKA. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program registry, we identified all primary unilateral UKAs from 2005 to 18. Patients were divided into three cohorts based on the operative duration: < 90 minutes, between 90 and 120 minutes, and >120 minutes. Baseline patient and operative demographics (age, gender, etc.) and thirty-day complications were compared using bivariate analysis. Multivariate analysis was used to assess the independent effect of operative duration on postoperative outcomes after adjusting for differences in baseline characteristics. RESULTS: We identified 11,806 patients who underwent primary UKA from 2005 to 18. There was no difference in the "any complication" rate between cohorts. However, operative duration >120 minutes was associated with a significantly higher likelihood of reoperation (odds ratio [OR] 2.02, 95% confidence interval [CI]: 1.15-3.57, P = .015), non-home discharge (OR: 2.14, CI: 1.65-2.77, P < .001), surgical site infection (OR: 1.76, CI: 1.03-3.01, P = .038), and blood transfusions (OR: 3.23, CI: 1.44-7.22, P = .004) when compared with operative duration <90 minutes. There was no difference in mortality rates. CONCLUSION: Increased operative duration greater than 2 hours in primary UKA is associated with an increased risk of non-home discharge, surgical site infection, reoperation, and blood transfusion.

Is surgical duration associated with postoperative complications in primary shoulder arthroplasty?

BACKGROUND: Surgical duration is an independent predictor of short-term adverse outcomes after a variety of orthopedic procedures, both arthroscopic and open. However, this association in shoulder arthroplasty remains unclear. The purpose of this study was to identify the association between surgical duration and postoperative complications, as well as increased use of health care resources, after shoulder arthroplasty. METHODS: Primary shoulder arthroplasty procedures performed from 2005 to 2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program database using Current Procedural Terminology codes. Surgical duration was divided into 3 cohorts: (1) surgical procedures lasting less than 90 minutes, (2) those lasting between 90 and 120 minutes, and (3) those lasting more than 120 minutes. Baseline patient characteristics and outcome variables were compared using bivariate analysis. Outcome variables were compared using multivariate analysis. RESULTS: Overall, 14,106 patients were identified. Longer surgical duration was significantly associated with younger age, male patients, higher body mass index, and use of general anesthesia, (P < .001 for each), as well as smoking history (P < .39). Relative to operative times shorter than 90 minutes, surgical procedures lasting more than 120 minutes had higher rates of any complication (P = .002), return to the operating room (P = .008), urinary tract infection (P = .02), non-home discharge (P < .001), blood transfusion (P < .001), and unplanned 30-day hospital readmission (P = .03). CONCLUSION: Increasing surgical duration was associated with a variety of postoperative medical complications and increased use of health care resources including discharge to acute care facilities, blood transfusions, and hospital readmission. These data suggest that surgical duration should be considered for postoperative risk stratification, as well as patient counseling, and may be a surgeon-modifiable risk factor independent of patient risk factors.

Frailty in ovarian cancer identified the need for increased postoperative care requirements following cytoreductive surgery.

OBJECTIVES: We sought to examine the relationship between frailty and complicated postoperative courses, including intensive care unit (ICU) admission and non-home discharge, in patients with advanced ovarian cancer (OC) undergoing primary debulking surgery (PDS) for curative intent. METHODS: Patients were identified from a retrospectively collected database at a single institution between 1/1/2003-12/31/2011. A frailty index was derived from 30 items representing comorbidities and activities of daily living, each scored as 0, 0.5, or 1, and calculated as the total summated score divided by the total number of non-missing items. Frailty was defined as an index ≥0.15. Associations with binary outcomes were assessed using logistic regression. RESULTS: A total of 535 patients met inclusion criteria. Frail patients were older, mean age 67.8 versus 63.2 years (p < 0.001), but there was no difference in grade, stage, or serous histology. Almost half of the frail patients (48.9%, 64/131) were admitted to the ICU compared to 20.5% (83/404) of non-frail patients. Frailty remained an independent predictor of 30-day ICU admission (adjusted odds ratio (aOR) 3.20, 95% CI: 2.03-5.06) in a multivariable model including age, preoperative albumin, surgical complexity, and residual disease. Frail patients were also more likely to have a non-home discharge (24.2% vs. 7.0%). Frailty independently predicted non-home discharge (aOR 2.58, 95% CI: 1.35-4.93) after adjusting for age, BMI, and stage. CONCLUSION: Frailty is a measurable, objective clinical syndrome that has impact on postoperative outcomes in advanced OC and should be considered when decision-making about treatments and counseling patients.

A machine-learning-based prediction of non-home discharge among acute heart failure patients.

BACKGROUND: Scarce data on factors related to discharge disposition in patients hospitalized for acute heart failure (AHF) were available, and we sought to develop a parsimonious and simple predictive model for non-home discharge via machine learning. METHODS: This observational cohort study using a Japanese national database included 128,068 patients admitted from home for AHF between April 2014 and March 2018. The candidate predictors for non-home discharge were patient demographics, comorbidities, and treatment performed within 2 days after hospital admission. We used 80% of the population to develop a model using all 26 candidate variables and using the variable selected by 1 standard-error rule of Lasso regression, which enhances interpretability, and 20% to validate the predictive ability. RESULTS: We analyzed 128,068 patients, and 22,330 patients were not discharged to home; 7,879 underwent in-hospital death and 14,451 were transferred to other facilities. The machine-learning-based model consisted of 11 predictors, showing a discrimination ability comparable to that using all the 26 variables (c-statistic: 0.760 [95% confidence interval, 0.752-0.767] vs. 0.761 [95% confidence interval, 0.753-0.769]). The common 1SE-selected variables identified throughout all analyses were low scores in activities of daily living, advanced age, absence of hypertension, impaired consciousness, failure to initiate enteral alimentation within 2 days and low body weight. CONCLUSIONS: The developed machine learning model using 11 predictors had a good predictive ability to identify patients at high risk for non-home discharge. Our findings would contribute to the effective care coordination in this era when HF is rapidly increasing in prevalence.

Octogenarians unable to return home by postoperative-day 30.

BACKGROUND: For older adults undergoing surgery, returning home is instrumental for functional independence. We quantified octogenarians unable to return home by POD-30, assessed geriatric factors in a predictive model, and identified risk factors to inform decision-making and quality improvement. METHODS: This retrospective cohort study examined patients ≥80 years old from the ACS NSQIP Geriatric Surgery Pilot, using sequential logistic regression modelling. The primary outcome was non-home living location at POD-30. RESULTS: Of 4946 patients, 19.8 â€‹% lived in non-home facilities at POD-30. Increased odds of non-home living location were seen in patients with preoperative fall history (OR 2.92, 95%CI 2.06-4.14) and new postoperative pressure ulcer (OR 2.66, 95%CI 1.50-4.71) Other significant geriatric-specific risk factors included mobility aid use, surrogate-signed consent, and postoperative delirium, with odds ratios ranging from 1.42 (1.19-1.68) to 1.97 (1.53-2.53). CONCLUSIONS: These geriatric-specific risk factors highlight the importance of preoperative vulnerability screening and intervention to inform surgical decision-making.

Six-Item Modified Frailty Index independently predicts complications following total shoulder arthroplasty.

Background: In the realm of orthopedic surgery, frailty has been associated with higher rates of complications following total hip and total knee arthroplasties. Among various measures of frailty, the Six-Item Modified Frailty Index (MF-6) has recently gained popularity as a predictor for postoperative complications. The purpose of this study was to investigate MF-6 as a predictor for early postoperative complications in the elderly patient population following total shoulder arthroplasty (TSA). Methods: The authors queried the American College of Surgeons National Surgical Quality Improvement Program database for all patients who underwent TSA between 2015 and 2020. Patient demographics and comorbidities were compared between cohorts using bivariate logistic regression analysis. Multivariate logistic regression, adjusted for all significantly associated patient demographics and comorbidities, was used to identify associations between the MF-6 score and postoperative complications. Results: Of total, 9228 patients were included in this study: 8764 (95.0%) had MF-6 <3, and 464 (5.0%) patients had MF-6 ≥3. Multivariate analysis found MF-6 ≥3 to be independently associated with higher rates of urinary tract infection (odds ratio [OR]: 2.79, 95% confidence interval [CI]: 1.49-5.23; P = .001), blood transfusion (OR: 1.53, 95% CI: 1.01-2.32; P = .045), readmission (OR: 1.58, 95% CI: 1.06-2.35; P = .024), and non-home discharge (OR: 2.60, 95% CI: 2.08-3.25; P < .001). Conclusion: A high MF-6 score (≥3) in patients aged 65 and older is independently associated with higher rates of urinary tract infection, blood transfusion, readmission, and non-home discharge following TSA. The MF-6 score can be easily calculated preoperatively and may allow for better preoperative risk stratification.

Does Surgical Day of Week Affect Patient Outcomes and Hospital Costs Following Lumbar Fusion?

Background As the population ages, surgical intervention for degenerative spine conditions is increasing, and this causes a commiserate increase in healthcare expenditures associated with these procedures. Little research has been done on the effect of early-week versus later-week surgeries on patient outcomes, cost, and length of stay (LOS) in patients undergoing lumbar fusion surgery. The purpose of this study is to compare LOS, patient outcomes, and hospital costs between patients having surgery early in the week and later in the week. Methods A retrospective review of 771 patients undergoing a one-, two-, or three-level lumbar fusion from December 2020 to December 2023 at a single institution was performed. Demographics, surgical details, postoperative outcomes and cost were compared between patients who had surgery on Monday, Tuesday, and Wednesday, to those having surgery Thursday or Friday. Univariate and multivariate analyses were performed to compare the groups. Results There were no differences in age, sex, BMI, race, American Society of Anesthesiology (ASA) scores, Charlson Comorbidity Index (CCI) scores, number of operative levels or inpatient/outpatient status between early- and late-week surgeries. Postoperatively the only significant difference was cost, late-week surgeries were, on average, $3,697 more expensive than early-week surgeries ($26,506 vs. $22,809; p<0.001). On multivariate analysis late-week surgeries were 2.47 times more likely to have a non-home discharge (OR: 2.47, 95% CI: 1.24 to 4.95; p=0.010) and 2.19 times more likely to have a 30-day readmission (OR: 2.19, 95% CI:1.01 to 4.74; p=0.044) Additionally, late-week surgeries were $2,041.55 (ß:2,041.55, 95% CI: 804.72 to 3,278.38; p=0.001) more expensive than early-week surgeries. Conclusions At our institution, patients undergoing one- to three-level lumbar fusion surgery on Thursday or Friday had a higher risk of non-home discharge, 30-day readmission, and incurred higher cost than those having early-week surgery. Further research is needed to elucidate the reasons for these findings and to evaluate interventions aimed at improving outcomes for patients undergoing surgery later in the week.

The Re-Evaluation of Frailty in Predicting Complications after Long-Segment Spinal Fusion for Adult Spinal Deformity.

OBJECTIVE: To evaluate on a national scale how frailty status (stratified using the 5-item Modified Frailty Index (mFI-5)) affects the operative characteristics of and complications after long-segment spinal fusion (LSF) for adult spinal deformity (ASD). METHODS: Adults undergoing LSF of ≥3 vertebrae in the National Surgical Quality Improvement Program database years 2015-2020 were split into 2 cohorts: nonfrail with mFI = 0 or 1; frail with mFI ≥2. Demographics, operative characteristics, and 30-day complications were contrasted between the cohorts using the Student's t-test, the Fisher's exact test, or a multivariate analysis when appropriate. RESULTS: In the 340 LSF cases collected, 268 fell into the nonfrail cohort and 72 into the frail cohort. The frail cohort constituted a high rate of geriatric age (65.3% vs. 38.1%; P < 0.001), higher body mass index (32.9 ± 0.86 vs. 30.2 ± 0.39; P = 0.005), and more comorbidities in 9 of 14 measures. After surgery, the frail cohort experienced more urinary tract infections (odds ratio [OR], 3.33; confidence interval [CI], 1.01-10.94; P = 0.04). However, the frail cohort shared similarities with the nonfrail cohort in terms of length of stay (5.11 ± 0.51 vs. 6.01 ± 1.62 days; P = 0.60), home discharge (OR, 0.76; CI, 0.42-1.39; P = 0.38), readmission (OR, 2.45; CI, 0.87-6.89; P = 0.09), and overall rate of complications (OR, 0.89; CI, 0.50-1.59; P = 0.70). CONCLUSIONS: Despite trends found in past studies of ASD, this analysis showed that the frailty status of mFI ≥2 is a poor predictor of surgical and hospitalization course and overall complications in LSF when examined up to 30 days postoperatively.

Baseline frailty status, not advanced patient age, predicts epilepsy surgery outcomes: An analysis of 696 patients from the NSQIP database.

OBJECTIVE: Preoperative risk stratification of patients undergoing epilepsy surgery remains challenging. Recently, the efforts to look beyond age alone as an outcomes predictor has resulted in the development of measures of physiological reserve, or 'frailty indices.' The most frequently cited index in neurosurgery is the 11-item or 5-item modified frailty index (mFI11 or mFI-5). The present study aimed to use a large national registry to evaluate the effect of frailty (as measured by mFI-5 versus age on postoperative outcomes of patients undergoing epilepsy surgery. METHODS: The National Surgical Quality Improvement Program (NSQIP) database, overseen by the American College of Surgeons (ACS), was used to extract data for patients undergoing epilepsy surgery from 2015 to 2019. Univariate and multivariate analyses for age and mFI-5 were performed for the following 30-day outcomes of extended length of hospital stay (eLOS) and non-home discharge (NHD). The effect sizes were summarized by odds ratio and associated 95 % confidence intervals. Receiver operating characteristic (ROC) curve analysis, including area under the curve (AUC), was used to quantify the discrimination. RESULTS: Univariate and multivariate analyses demonstrated that frailty statuses from mFI-5, not age, were significantly predictive of eLOS and NHD. On ROC curve analysis, mFI-5 was a stronger predictor of eLOS (C = 0.59, 95 % CI 0.54-0.64, p < 0.001) and NHD (C = 0.69, 95 % CI 0.64-0.76, p < 0.001) than age (C = 0.53, 95 % CI 0.48-0.58, p = 0.21 and C = 0.53, 95 % CI 0.46-0.59, p = 0.44, respectively). CONCLUSION: Frailty, not age, is an independent risk factor for poor postoperative outcomes, particularly eLOS and NHD, in patients undergoing epilepsy surgery. Usage of mFI-5 for preoperative risk stratification of epilepsy surgery patients can help in prognostication.

Multi-institutional Cohort Study of Elective Diverticulitis Surgery: a National Surgical Quality Improvement Program Database Analysis to Identify Predictors of Non-home Discharge Among Older Adults.

BACKGROUND: Older adults often prioritize independence and time spent at home when making major treatment decisions. Identifying preoperative predictors of non-home discharge (i.e., requiring institutional discharge rather than home), among adults undergoing elective diverticulitis surgery, can support surgical decision-making and expectation management. This study aims to (1) examine rates of non-home discharge after elective surgery for diverticulitis and (2) identify predictors of non-home discharge. METHODS: This is a multi-institutional cohort study of National Surgical Quality Improvement Program Database. Patients over 18 years who underwent colon resection with diagnosis of diverticulitis were included. Clinical and demographic information were collected by trained nurse reviewers. Emergency operations were excluded. Patients with home versus non-home discharge were compared and predictors identified using multivariable regression. RESULTS: Between 2016 and 2019, 40,912 patients were identified. Mean age was 58.5 years (SD = 12.58) with 48.5% 60 + years and 17.7% of patients 70 + years old. The majority (55.9%) were female and "White" race (83.5%). Most patients underwent colectomy without ostomy (88.4%). Nine percent of patients over age 60 had non-home discharge. Functional dependence preoperatively was strongly associated with non-home discharge. On multivariable analysis, significant predictors of non-home discharge were preoperative functional dependence (OR 28.2; 95% CI 9.8-81.7), advancing chronologic age (age 80 + : OR 22.4; 95% CI 18.6-26.9), and preoperative albumin < 3.0 (OR 4.0; 95% CI 3.4-4.6). CONCLUSIONS: Nearly one in ten patients over 60 years was not discharged home after elective diverticulitis surgery. Preoperative functional status predicts non-home discharge. Future studies need to assess potentially modifiable causes of non-home discharge, such as social support.

Comparison of outcomes after transcatheter aortic valve implantation following home versus non-home discharge.

As more patients undergo transcatheter aortic valve implantation (TAVI), knowledge of 1-year mortality and associated factors becomes increasingly important. After other cardiac procedures, discharge location has been shown to be associated with 1-year mortality. We examined outcomes of TAVI patients discharged home vs an extended care facility (ECF). All TAVI patients from January 1, 2012, to December 31, 2017, were evaluated. Cox proportional hazard regression models with cubic splines were used to estimate the adjusted effect of discharge to ECF on 1-year mortality. A total of 957 (85.6%) patients discharged home were compared to 160 (14.3%) discharged to ECF. On univariate analysis, patients discharged home were younger and had a lower Society of Thoracic Surgeons Predicted Risk of Mortality, higher albumin, and fewer vascular complications and strokes. Patients discharged to ECF had a higher 30-day mortality (3.8% vs. 0.5%, P = 0.001) and 1-year mortality (25.7% vs. 8.3%, P < 0.001). Cox proportional hazard regression models showed increased risk of 1-year mortality for patients discharged to ECF. In conclusion, patients discharged to ECF had a higher 30-day and 1-year mortality. The strongest predictor of 1-year mortality was discharge to ECF. Society of Thoracic Surgeons Predicted Risk of Mortality score was not a predictor of 1-year mortality.

Readmission, reoperation, and nonhome discharge rates in patients receiving surgical treatment for proximal humerus fractures.

Background: Proximal humerus fractures (PHFs) are generally surgically treated with open reduction internal fixation (ORIF), hemiarthroplasty (HA), or total shoulder arthroplasty (TSA). Diverse fracture patterns and a high prevalence in the elderly population make it difficult to establish objective guidelines for the decision to undergo surgical treatment. The purpose of this study was to investigate risk factors associated with readmission, reoperation, and nonhome discharge following ORIF, HA, and TSA for PHFs. Methods: Data on all patients who underwent ORIF, TSA, or HA for treatment of closed PHF between 2015 and 2017 were obtained by querying the American College of Surgeons National Surgical Quality Improvement database. Rates of postoperative readmission, nonhome discharge, and reoperation within 30 days were collected. Multivariate logistic regression was employed to identify predictors of readmission, nonhome discharge, and reoperation. Results: A total of 2825 patients were included in this study: 1829 underwent ORIF, 707 underwent TSA, and 289 underwent HA. The significant predictors for readmission were having an American Society of Anesthesiologists class ≥ 3 (odds ratio [OR] 1.95, P = .003) and being of dependent functional status (OR 3.15, P < .001). The significant predictors for reoperation were male sex (OR 2.41, P < .001) and dependent functional status (OR 2.92, P = .006). The significant predictors for nonhome discharge were age 66-80 years (OR 7.00, P < .001), age ≥ 81 years (OR 16.31, P < .001), American Society of Anesthesiologists ≥3 (OR 2.34, P < .001), dependent functional status (OR 2.48, P < .001), and inpatient status (OR 3.32, P < .001). TSA showed slightly higher rates of nonhome discharge than HA and ORIF. Conclusion: Significant risk factors for readmission, reoperation, and nonhome discharge within 30 days following surgical treatment for PHF were identified. Additionally, TSA was significantly associated with nonhome discharge compared with HA and ORIF.

AM-PAC mobility scores predict non-home discharge following adult spinal deformity surgery.

BACKGROUND CONTEXT: Adult spinal deformity (ASD) surgery requires an extended recovery period and often non-routine discharge. The Activity Measure for Post-Acute Care (AM-PAC) Basic Mobility Inpatient Short Form (6-Clicks) is a prediction tool, validated for other orthopedic procedures, to assess a patient's ability to mobilize after surgery. PURPOSE: To assess the thresholds of AM-PAC scores that determine non-home discharge disposition in patients who have undergone ASD surgery. STUDY DESIGN: Retrospective review PATIENT SAMPLE: Ninety consecutive ASD patients with ≥5 levels fused who underwent surgery from 2015 to 2018, with postoperative AM-PAC scores measured before discharge, were included. OUTCOME MEASURES: Non-home discharge disposition METHODS: Patients with routine home discharge were compared to those with non-home discharge. Bivariate analysis was first conducted to compare these groups by preoperative demographics, comorbidities, radiographic alignment, surgical characteristics, HRQOLs, and AM-PAC measurements. Threshold linear regression with Bayesian information criteria was utilized to identify the optimal cutoffs for AM-PAC scores associated with increased likelihood of non-home discharge. Finally, multivariable analysis controlling for age, sex, comorbidities, levels fused, perioperative complication, and home support was conducted to assess each threshold. RESULTS: Thirty-six (40%) of 90 patients analyzed had non-home discharge. On bivariate analysis, first AM-PAC score (13.5 vs. 17), last AM-PAC score (17 vs. 20), and AM-PAC change per day (+.387 vs. +1) were all significantly associated with non-home discharge. Threshold regression identified that cutoffs of ≤15 for first AM-PAC score, <17 for last AM-PAC score, and <+0.625 for daily AM-PAC change were associated with non-home discharge. On multivariable analysis, first AM-PAC score ≤15 (odds ratio [OR] 11.28; confidence interval [CI] 2.96-42.99; p<.001), last AM-PAC score <17 (OR 33.57; CI 5.85-192.82; p<.001), and AM-PAC change per day <+0.625 (OR 6.24; CI 2.01-19.43; p<.001) were all associated with increased odds of non-home discharge. CONCLUSIONS: First AM-PAC score of 15 or less can help predict non-home discharge. A goal of daily AM-PAC increases of 0.625 points toward a final AM-PAC score of 17 can aid in achieving home discharge. The early AM-PAC mobility threshold of ≤15 may help prepare for non-home discharge, while AM-PAC daily changes per day <0.625 and final AM-PAC <17 may provide goals for mobility improvement during the early postoperative period in order to prevent non-home discharge.

Risk for non-home discharge following surgery for ischemic mitral valve disease.

OBJECTIVES: To determine the frequency and risk factors for non-home discharge (NHD) and its association with clinical outcomes and quality of life (QOL) at 1 year following cardiac surgery in patients with ischemic mitral regurgitation (IMR). METHODS: Discharge disposition was evaluated in 552 patients enrolled in trials of severe or moderate IMR. Patient and in-hospital factors associated with NHD were identified using logistic regression. Subsequently, association of NHD with 1-year mortality, serious adverse events (SAEs), and QOL was assessed. RESULTS: NHD was observed in 30% (154/522) with 25% (n = 71/289) in moderate and 36% (n = 83/233) in patients with severe IMR (unadjusted P = .006), a difference not significant after including age (5-year change: adjusted odds ratio [adjOR], 1.52; 95% confidence interval [CI], 1.35-1.72; P < .001), diabetes (adjOR, 1.94; 95% CI, 1.27-2.94; P = .002), and previous heart failure (adjOR, 1.64; 95% CI, 1.06-2.52; P = .03). Odds of NHD were increased for patients with postoperative SAEs (adjOR, 1.85; 95% CI, 1.19-2.86; P = .01) but not based on type of cardiac surgery. Greater rates of death and SAEs were observed in NHD patients at 1 year: adjusted hazard ratio, 4.29 (95% CI, 2.14-8.59; P < .001) and adjusted rate ratio, 1.45 (95% CI, 1.03-2.02; P = .03), respectively. QOL did not differ significantly between groups. CONCLUSIONS: NHD is common following surgery for IMR, influenced by older age, diabetes, previous heart failure, and postoperative SAEs. These patients may be at greater risk of death and subsequent SAEs after discharge. Discussion of NHD with patients may have important implications for decision-making and guiding expectations following cardiac surgery.

Risk scoring model for prediction of non-home discharge after transcatheter aortic valve replacement.

BACKGROUND: Patients undergoing transcatheter aortic valve replacement (TAVR) are likely to be discharged to a location other than home. We aimed to determine the association between preoperative risk factors and non-home discharge after TAVR. METHODS: Patients discharged alive after TAVR at three centers were identified from a prospectively maintained database randomly divided into 80% derivation and 20% validation cohorts. Logistic regression models were fit to identify preoperative factors associated with non-home discharge in the derivation cohort. Multivariable models were developed and a nomogram based risk-scoring system was developed for use in preoperative counseling. RESULTS: Between June 2012 and December 2018, a total of 1, 163 patients had TAVR at three centers. Thirty-seven patients who died before discharge were excluded. Of the remaining 1, 126 patients (97%) who were discharged alive, the incidence of non-home discharge was 25.6% (n = 289). The patient population was randomly divided into the 80% (n = 900) derivation cohort and 20% (n = 226) validation cohort. Mean ± SD age of the study population was 83 ± 8 years. In multivariable analysis, factors that were significantly associated with non-home discharge were extreme age, female sex, higher STS scores, use of general anesthesia, elective procedures, chronic liver disease, non-transfemoral approach and postoperative complications. The unbiased estimate of the C-index was 0.81 and the model had excellent calibration. CONCLUSIONS: One out of every four patients undergoing TAVR is discharged to a location other than home. Identification of preoperative factors associated with non-home discharge can assist patient counseling and postoperative disposition planning.

Factors associated with non-home discharge after total knee arthroplasty: Potential for cost savings?

INTRODUCTION: Increasing demand for total knee arthroplasties (TKA) has been targeted by legislation to minimize costs and maximize outcomes. Home discharges reduce costs, and it is important to determine patient variables associated with this discharge disposition. We explored non-modifiable and modifiable factors associated with non-home discharges to determine what patient specific factors require attention. METHODS: This retrospective study included 171,903 National Surgical Quality Improvement Program (NSQIP) patients between 2011 and 2016. Patient specific variables and discharge destinations included home, short-term nursing facilities (SNF), not home, and rehabilitation. Chi-squared analyses and analyses of variance (ANOVA) were conducted for categorical and continuous data, respectively. Multinomial regression model was utilized to assess associations between discharge destination and patient specific variables. RESULTS: Every year increase above the mean age (66 years) was associated with a nine percent (p < .001) and six percent (p < .001) increased odds for discharge to SNF or rehabilitation, respectively, compared to home discharges. Every 10% increase in BMI from the mean was associated with a 10% increase in discharge to both SNF and rehabilitation (p < .001 for both). CONCLUSION: With increasing demands for TKAs and expenditures to Medicare, evaluating factors that impact patient discharge can help optimize costs and outcomes of TKA procedures. Arthroplasty surgeons can benefit by recognizing these correlations and exploring reductions to non-home discharges through pre-operative patient optimization. Future studies should evaluate the economic cost potential associated with optimizing routine home discharge in TKA patients. LEVEL OF EVIDENCE: IV.
