Long-Term Fate of Patients Discharged to Extended Care Facilities After Cardiovascular Surgery

The relationship between discharge location and cardiac rehabilitation use after cardiac surgery

BACKGROUND

Cardiac rehabilitation (CR) is a guideline-recommended risk-reduction program offered to cardiac surgical patients. Despite CR's association with better outcomes, attendance remains poor. The relationship between discharge location and CR use is poorly understood.

METHODS

This study was a nationwide, retrospective cohort analysis of Medicare fee-for-service claims for beneficiaries undergoing coronary artery bypass grafting and/or surgical aortic valve repair between July 1, 2016, and December 31, 2018. The primary outcome was attendance of any CR session. Discharge location was categorized as home discharge or discharge to extended care facility (ECF) (including skilled nursing facility, inpatient rehabilitation, and long-term acute care). Multivariable logistic regression models evaluated the association between discharge location, CR attendance, and 1-year mortality.

RESULTS

Of the 167,966 patients who met inclusion criteria, 34.1% discharged to an ECF. Overall CR usage rate was 53.9%. Unadjusted and adjusted CR use was lower among patients discharged ECFs versus those discharged home (42.1% vs 60.0%; adjusted odds ratio, 0.66; P < .001). Patients discharged to long-term acute care were less likely to use CR than those discharged to skilled nursing facility or inpatient rehabilitation (reference category: home; adjusted odds ratio for long-term acute care, 0.36, adjusted odds ratio for skilled nursing facility, 0.69, and adjusted odds ratio for inpatient rehabilitation, 0.71; P < .001). CR attendance was associated with a greater reduction in adjusted 1-year mortality in patients discharged to ECFs (9.7% reduction) versus those discharged home (4.3% reduction).

CONCLUSIONS

In this national analysis of Medicare beneficiaries, discharge to ECF was associated with lower CR use, despite a greater association with improved 1-year mortality. Interventions aimed at increasing CR enrollment at ECFs may improve CR use and advance surgical quality.

Frailty and Long-Term Survival in Patients With Critical Illness After Nonhome Discharge: A Retrospective Cohort Study

IMPORTANCE

Patients with frailty are more frequently discharged to rehabilitation or residential aged care facility (RACF), defined as nonhome discharge, than those without frailty. An increase in nonhome discharge is considered to be one of the collateral "costs" associated with declining hospital mortality. However, it is unclear whether this association applies to patients with frailty, particularly in the long term.

OBJECTIVES

To determine the impact of frailty on long-term survival in patients who had a nonhome discharge following an ICU admission.

DESIGN

A retrospective multicenter cohort study.

SETTING AND PARTICIPANTS

All medical patients (≥ 16 yr old) admitted to Australian and Zealand ICUs, with a documented Clinical Frailty Scale (CFS) and a nonhome discharge from January 1, 2018, to March 31, 2022, were included.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Primary outcome was survival time up to 4 years. We used Cox proportional hazards regression models with robust sandwich variance estimators to assess the effect of frailty (defined as CFS = 5-8) on survival time after ICU admission between groups. We also analyzed the effect of frailty on long-term survival based on their age and nonhome discharge location. Of the 57,652 patients, 17,383 (30.2%) were frail. Overall 4-year survival was lower in patients with frailty than those without (32.5% vs. 64.3%; p < 0.001). Frailty was associated with shorter survival times (adjusted hazard ratio [aHR], 1.50; 95% CI, 1.43-1.57). Frailty was associated with a greater reduction in survival in patients younger than 65 years old (aHR, 1.73; 95% CI, 1.59-1.88), 65-80 years (aHR, 1.47; 95% CI, 1.38-1.57), or older than 80 years (aHR, 1.35; 95% CI, 1.26-1.45). Frailty was associated with greater reduction in survival in those discharged to rehabilitation (aHR, 1.52; 95% CI, 1.39-1.65) or acute hospitals (aHR, 1.56; 95% CI, 1.48-1.65) than those discharged to RACF (aHR, 0.94; 95% CI, 0.83-1.06).

CONCLUSIONS

Frailty was independently associated with shorter time to death following a nonhome discharge after an ICU admission.

RELEVANCE

There was an independent association between patients with frailty admitted to ICU and had a nonhome discharge with the shorter time to death than those without frailty.

A Novel Preoperative Risk Score to Identify Patients at High Risk for Nonhome Discharge after Elective Open Abdominal Aortic Aneurysm Repair

BACKGROUND

Nonhome 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 health-care spending. Understanding postsurgical NHD risk is essential to preoperative counseling and shared decision making. This is particularly true for the treatment of abdominal aortic aneurysms (AAAs) 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 Society for Vascular Surgery 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 chronic obstructive pulmonary disease (COPD, 41.6% vs. 30.7%), American Society of Anesthesiologists (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), COPD, female sex, hypertension, and ASA 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.

Factors associated with nonhome discharge after endovascular aneurysm repair

OBJECTIVE

This study aims to identify preoperative factors associated with nonhome discharge (NHD) after endovascular aneurysm repair (EVAR). NHD has implications for patient care, readmission, and long-term mortality; nevertheless, the existing literature lacks information regarding factors associated with NHD for patients undergoing EVAR. In contrast, our study assesses preoperative factors associated with NHD for this population by using national data from the Vascular Quality Initiative.

METHODS

We identified adult patients who underwent elective EVAR in the Vascular Quality Initiative (2003-2022) and excluded those who were not living at home preoperatively. Multivariable logistic regression was used to identify preoperative factors associated with NHD. Kaplan-Meier methods and Cox-regression analyses were used to assess the impact of NHD on 5-year survival as a secondary outcome.

RESULTS

We included 61,792 patients, of which 3155 (5.1%) had NHD. NHD patients were more likely to be older (79 years [interquartile range, 73-18 years] vs 73 years [interquartile range, 67-79 years]), female (33.7% vs 18.2%; P < .001), non-White (16.0% vs 11.7%; P < .001), and have more comorbidities. NHD patients had higher rates of postoperative complications (acute kidney injury, 11.9% vs 2.0% [P < .001]; myocardial infarction, 3.8% vs 0.5% [P < .001]; and in-hospital reintervention, 4.7% vs 0.5% [P = .033]). Multivariable analysis revealed many preoperative characteristics were associated with higher odds of NHD: most notably, age (per additional decade: odds ratio [OR], 2.15; 95% confidence interval [CI], 2.03-2.28; P < .001), female sex (OR, 1.79; 95% CI, 1.63-1.95; P < .001) and aneurysm diameter >65 mm (OR, 2.18; 95% CI, 1.98-2.39; P < .001), along with potentially modifiable factors, including anemia, chronic obstructive pulmonary disease, chronic heart failure, weight, and diabetes. In contrast, aspirin, statin, and angiotensin-converting enzyme inhibitor/angiotensin II receptor blocekr use were associated with lower odds of NHD. NHD was associated with higher hazards of 5-year mortality, even after adjusting for confounders (40% vs 14%; adjusted hazard ratio, 2.13; 95% CI, 1.86-2.44; P < .001).

CONCLUSIONS

Several factors were associated with higher odds of NHD after elective EVAR, including nonmodifiable factors such as female sex and larger aortic diameter, and potentially modifiable factors such as anemia, chronic obstructive pulmonary disease, chronic heart failure, body mass index, and diabetes. Special attention should be given to populations with nonmodifiable factors, and efforts at optimizing medical conditions with higher NHD likelihood seems appropriate to improve patient outcomes and quality of life after EVAR.

Predictors and outcomes of discharge to long-term acute care facilities after cardiac surgery

OBJECTIVE

An increasing number of patients with significant comorbidities present for complex cardiac surgery, with a subgroup requiring discharge to long-term acute care facilities. We aim to examine predictors and mortality after discharge to a long-term acute care facility.

METHODS

From January 1, 2015, to April 30, 2021, all adult cardiac surgeries were queried and patients discharged to long-term acute care facilities were identified. Baseline characteristics, procedures, and in-hospital complications were compared between long-term acute care facility and non-long-term acute care facility discharges. Random forest analysis was conducted to establish predictors of discharge to long-term acute care facilities. Kaplan-Meier survival analysis was used to determine probability of survival over 7 years. Multivariate regression modeling was used to establish predictors of death after long-term acute care facility discharge.

RESULTS

Of 29,884 patients undergoing cardiac surgery, 324 (1.1%) were discharged to a long-term acute care facility. The long-term acute care facility group had higher rates of urgent/emergency operation (54% vs 23%; 10% vs 3%, P < .001) and longer mean cardiopulmonary bypass (167 vs 110 minutes, P < .001). By random forest analysis, emergency/urgent status, longer cardiopulmonary bypass duration, redo surgery, endocarditis, and history of dialysis were the most predictive of discharge to a long-term acute care facility. Although the non-long-term acute care facility group demonstrated greater than 95% survival at 6 months, Kaplan-Meier survival analysis showed 28% 6-month mortality in the long-term acute care facility cohort. Random forest analysis demonstrated that chronic lung disease and postoperative respiratory complications were significant predictors of death at 6 months after discharge to a long-term acute care facility.

CONCLUSIONS

Patients with chronic lung and kidney disease undergoing prolonged procedures are at higher risk to be discharged to long-term acute care facilities after surgery with worse survival. Efforts to minimize postoperative respiratory complications may reduce mortality after discharge to long-term acute care facilities.

Are All Patients Going Home after Total Knee Arthroplasty? A Temporal Analysis of Discharge Trends and Predictors of Nonhome Discharge (2011-2020)

Value-based orthopaedic surgery and reimbursement changes for total knee arthroplasty (TKA) are potential factors shaping arthroplasty practice nationwide. This study aimed to evaluate (1) trends in discharge disposition (home vs nonhome discharge), (2) episode-of-care outcomes for home and nonhome discharge cohorts, and (3) predictors of nonhome discharge among patients undergoing TKA from 2011 to 2020. The National Surgical Quality Improvement Program database was reviewed for all primary TKAs from 2011 to 2020. A total of 462,858 patients were identified and grouped into home discharge (n = 378,771) and nonhome discharge (n = 84,087) cohorts. The primary outcome was the annual rate of home/nonhome discharges. Secondary outcomes included trends in health care utilization parameters, readmissions, and complications. Multivariable logistic regression analyses were performed to evaluate factors associated with nonhome discharge. Overall, 82% were discharged home, and 18% were discharged to a nonhome facility. Home discharge rates increased from 65.5% in 2011 to 94% in 2020. Nonhome discharge rates decreased from 34.5% in 2011 to 6% in 2020. Thirty-day readmissions decreased from 3.2 to 2.4% for the home discharge cohort but increased from 5.6 to 6.1% for the nonhome discharge cohort. Female sex, Asian or Black race, Hispanic ethnicity, American Society of Anesthesiology (ASA) class > II, Charlson comorbidity index scores > 0, smoking, dependent functional status, and age > 60 years were associated with higher odds of nonhome discharge. Over the last decade, there has been a major shift to home discharge after TKA. Future work is needed to further assess if perioperative interventions may have a positive effect in decreasing adverse outcomes in nonhome discharge patients.

Survivorship outcomes for critically ill patients in Australia and New Zealand: A scoping review

INTRODUCTION

Impairments after critical illness, termed the post-intensive care syndrome, are an increasing focus of research in Australasia. However, this research is yet to be cohesively synthesised and/or summarised.

OBJECTIVE

The aim of this scoping review was to explore patient outcomes of survivorship research, identify measures, methodologies, and designs, and explore the reported findings in Australasia.

INCLUSION CRITERIA

Studies reporting outcomes for adult survivors of critical illness from Australia and New Zealand in the following domains: physical, functional, psychosocial, cognitive, health-related quality of life (HRQoL), discharge destination, health care use, return to work, and ongoing symptoms/complications of critical illness.

METHODS

The Joanna Briggs Institute scoping review methodology framework was used. A protocol was published on the open science framework, and the search used Ovid MEDLINE, Scopus, ProQuest, and Google databases. Eligible studies were based on reports from Australia and New Zealand published in English between January 2000 and March 2022.

RESULTS

There were 68 studies identified with a wide array of study aims, methodology, and designs. The most common study type was nonexperimental cohort studies (n = 17), followed by studies using secondary analyses of other study types (n = 13). HRQoL was the most common domain of recovery reported. Overall, the identified studies reported that impairments and activity restrictions were associated with reduced HRQoL and reduced functional status was prevalent in survivors of critical illness. About 25% of 6-month survivors reported some form of disability. Usually, by 6 to12 months after critical illness, impairments had improved.

CONCLUSIONS

Reports of long-term outcomes for survivors of critical illness in Australia highlight that impairments and activity limitations are common and are associated with poor HRQoL. There was little New Zealand-specific research related to prevalence, impact, unmet needs, ongoing symptoms, complications from critical illness, and barriers to recovery.

Development and Validation of a Novel Preoperative Risk Score to Identify Patients at Risk for Nonhome Discharge after Elective Endovascular Aortic Aneurysm Repair (EVAR)

BACKGROUND

Nonhome discharge (NHD) to a rehabilitation or skilled nursing facility after elective endovascular aortic repair (EVAR) is uncommon. However, NHD after surgery has an important impact on patient quality of life and postdischarge outcomes. Understanding factors that put patients undergoing EVAR at high risk for NHD is essential to providing adequate preoperative counseling and shared decision making. This study aimed to identify independent predictors of NHD following elective EVAR and to create a clinically useful preoperative risk score.

METHODS

Elective EVAR cases were queried from the Society for Vascular Surgery Vascular Quality Initiative 2014-2018. 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, 24,426 patients were included and 932 (3.8%) required NHD. Multivariable analysis in the development group identified independent predictors of NHD, which were used to create a 20-point risk score. Patients were stratified into 3 groups based upon their risk score: low risk (0-7 points; n = 16,699) with an NHD rate of 1.8%, moderate risk (8-13 points; n = 7,315) with an NHD rate of 7.3%, and high risk (≥14 points; n = 412) with an NHD rate of 21.8%. The risk score had good predictive ability with c-statistic = 0.75 for model development and c-statistic = 0.73 in the validation dataset.

CONCLUSIONS

This novel risk score can predict NHD following EVAR using characteristics that can be identified preoperatively. Utilization of this score may allow for improved risk assessment, preoperative counseling, and shared decision making.

Hospital Variation in Skilled Nursing Facility Use After Coronary Artery Bypass Graft Surgery

BACKGROUND

Over 20% of patients are discharged to a skilled nursing facility (SNF) after coronary artery bypass graft surgery, but little is known about specific drivers for postdischarge SNF use. The purpose of this study was to evaluate hospital variation in SNF use and its association with postoperative outcomes after coronary artery bypass graft.

METHODS AND RESULTS

A retrospective study design utilizing Medicare Provider Analysis and Review files was used to evaluate SNF use among 70 509 beneficiaries undergoing coronary artery bypass graft, with or without valve procedures, between 2016 and 2018. A total of 17 328 (24.6%) were discharged to a SNF, ranging from 0% to 88% across 871 hospitals. Multilevel logistic regression models identified significant patient-level predictors of discharge to SNF including increasing age, comorbidities, female sex, Black race, dual eligibility, and postoperative complications. After adjusting for patient and hospital factors, 15.6% of the variation in hospital SNF use was attributed to the discharging hospital. Compared with the lower quartile of hospital SNF use, hospitals in the top quartile of SNF use had lower risk-adjusted 1-year mortality (12.5% versus 8.6%, P<0.001) and readmission (59.9% versus 49.8%, P<0.001) rates for patients discharged to a SNF.

CONCLUSIONS

There is high variability in SNF use among hospitals that is only partially explained by patient characteristics. Hospitals with higher SNF utilization had lower risk-adjusted 1-year mortality and readmission rates for patients discharged to a SNF. More work is needed to better understand underlying provider and hospital-level factors contributing to SNF use variability.

Determinants and Outcomes Associated With Skilled Nursing Facility Use After Coronary Artery Bypass Grafting: A Statewide Experience

BACKGROUND

Skilled nursing facility (SNF) care is frequently used after cardiac surgery, but the patterns and determinants of use have not been well understood. The objective of this study was to evaluate determinants and outcomes associated with SNF use after isolated coronary artery bypass grafting.

METHODS

A retrospective analysis of Medicare Fee-For-Service claims linked to the Society of Thoracic Surgeons clinical data was conducted on isolated coronary artery bypass grafting patients without prior SNF use in Michigan between 2011 and 2019. Descriptive analysis evaluated the frequency, trends, and variation in SNF use across 33 Michigan hospitals. Multivariable mixed-effects regression was used to evaluate patient-level demographic and clinical determinants of SNF use and its effect on short- and long-term outcomes.

RESULTS

In our sample of 8614 patients, the average age was 73.3 years, 70.5% were male, and 7.7% were listed as non-White race. An SNF was utilized by 1920 (22.3%) patients within 90 days of discharge and varied from 3.2% to 58.3% across the 33 hospitals. Patients using SNFs were more likely to be female, older, non-White, with more comorbidities, worse cardiovascular function, a perioperative morbidity, and longer hospital lengths of stay. Outcomes were significantly worse for SNF users, including more frequent 90-day readmissions and emergency department visits and less use of home health and rehabilitation services. SNF users had higher risk-adjusted hazard of mortality (hazard ratio, 1.41 [95% CI, 1.26-1.57]; P<0.001) compared with non-SNF users and had 2.7-percentage point higher 5-year mortality rate in a propensity-matched cohort of patients (18.1% versus 15.4%; P<0.001).

CONCLUSIONS

The use of SNF care after isolated coronary artery bypass grafting was frequent and variable across Michigan hospitals and associated with worse risk-adjusted outcomes. Standardization of criteria for SNF use may reduce variability among hospitals and ensure appropriateness of use.

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 major depression disorder on neurogenic thoracic outlet syndrome surgery outcomes

OBJECTIVES

Thoracic outlet syndrome (TOS) is a group of disorders caused by impingement of the neurovascular structures at the thoracic outlet. Neurogenic TOS (nTOS), which is thought to be caused by a compression of the brachial plexus, accounts for more than 90% of the cases. Although treatment for nTOS is successful through physiotherapy and/or surgical decompression, little is known about the impact of psychosocial factors, namely, major depressive disorder (MDD), on postoperative outcomes such as non-routine discharge (NRD). Here, we assess whether MDD predicts the type of discharge following nTOS surgical intervention.

METHODS

A retrospective analysis of the National Inpatient Sample database from the years 2005-2018 was performed. Using the International Classification of Diseases Clinical Modification, Ninth and Tenth revisions, patients who underwent a surgical intervention for nTOS were identified. Our primary outcome was to investigate the effects of MDD on nTOS patient disposition status after surgical management; secondary outcomes included analysis of total hospital charges and length of stay. NRD was defined as anything beyond discharge home without healthcare services. Univariate and multivariable logistic regression analyses were conducted to assess MDD and other potential independent predictors of NRD and prolonged hospital stay (> 2 days) following surgical intervention.

RESULTS

A total of 6099 patients were identified: 596 (9.77%) patients with MDD and 5503 (90.23%) without MDD. On average, patients with MDD were older (39.6 ± 12.0 years vs. 36.0 ± 13.0 years; p < 0.001), female (80.7% vs. 63.5%; p < 0.001), white (89.6% vs. 85.6%; p = 0.030), and on Medicare (9.6% vs 5.2%; p < 0.001). Univariate and multivariable logistic regression models identified MDD as an independent risk factor associated with a higher risk of NRD (adjusted odds ratio [aOR], 1.50; 95% confidence interval [CI], 1.0-2.2). Additionally, chronic kidney disease (aOR, 2.60; 95% CI, 1.2-5.4), postoperative complications (aOR, 1.87; 95% CI, 1.2-2.9), and Medicare (aOR, 2.95; 95% CI, 1.9-4.7) were statistically significant predictors for higher risk of NRD. However, MDD was not associated with prolonged hospital stay (aOR, 1.00; 95% CI, 0.8-1.2) or higher median of total charges (MDD group: $27,867 vs. non-MDD group: $28,123; p = 0.799).

CONCLUSION

Comorbid MDD was strongly associated with higher NRD rates following nTOS surgical intervention. MDD had no significant impact on length of hospital stay or total hospital charges. Additional prospective research is necessary in order to better evaluate the impact of MDD in patients with nTOS.

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.

Skilled Nursing Facility Quality Rating and Surgical Outcomes Following Coronary Artery Bypass Grafting

Centers for Medicare and Medicaid Services created a 5-star quality rating system to evaluate skilled nursing facilities (SNFs). Patient discharge to lower-star quality SNFs has been shown to adversely impact surgical outcomes. Recent data has shown that over 20% of patients are discharged to an SNF after CABG, but the link between SNF quality and CABG outcomes has not been established. The purpose of this study is to evaluate the impact of SNF quality ratings on postoperative outcomes after CABG. Retrospective cohort review of Medicare patients undergoing CABG and discharged to an SNF between the years 2016-2017. Patients were categorized into 3 groups according to the star rating of the SNF with receipt of care after discharge (ie, below average, average, above average). Risk-adjusted 30-day to 1-year outcomes of mortality, readmission, and SNF length of stay were calculated and compared using multivariable logistic regression and Poisson models across SNF quality categories. Of the 73,164 Medicare patients in our sample, 15,522 (21.2%) were discharged to an SNF. Patients in below average SNFs were more likely to be younger, Black, Medicare/Medicaid dual eligible, and have more comorbidities. Compared to above average SNFs, patients discharged to below average SNFs experienced higher risk-adjusted 30-day mortality (2.1% vs 1.6%, P<0.02), readmission (21.6% vs 19.3%, P<0.01) and SNF length of stay (17.3d vs 16.5d, P<0.0001). Within 90-days, below average SNFs experienced higher risk-adjusted readmission rates (31.7% vs 30.0%, P<0.004). Outcomes at 1-year were not statistically significant. Medicare beneficiaries discharged to lower quality SNFs experienced worse postoperative outcomes after CABG. Identifying best practices at high performing SNFs, to potentially implement at low performing facilities, may improve equitable care for patients.

Impact of high-risk features and timing of repair for acute type B aortic dissections

OBJECTIVE

The new Society for Vascular Surgery/Society for Thoracic Surgery reporting standards for type B aortic dissection (TBAD) categorize clinical presentations of aortic dissection into uncomplicated, high-risk features (HRF), and complicated groups. Although it is accepted that complicated dissections require immediate repair, the optimal timing of repair for HRF has yet to be established. This study aims to identify the ideal timing of thoracic endovascular aortic repair (TEVAR) for HRF, as well as outcomes associated with specific HRF.

METHODS

The Vascular Quality Initiative was queried for TEVARs performed for acute and subacute TBAD with HRF from 2014 to 2020. Rupture, malperfusion, and uncomplicated patients were excluded. HRF were defined per the guidelines as refractory hypertension, pain, or rapid expansion/aneurysm of more than 40 mm. The primary outcomes were in-hospital/30-day mortality and 1-year survival with primary exposure variables being days from symptoms to repair and number of HRFs. Secondary outcomes were spinal cord ischemia, stroke, and retrograde type A dissection (RTAD).

RESULTS

Of the 1100 patients who met inclusion criteria, 811 had one HRF, 249 had two, and 40 had three. There were no significant differences in primary or secondary outcomes based on number of HRFs. There were 309 patients who underwent repair at 0 to 2 days, 262 at 3 to 6 days, 270 at 7 to 14 days, and 259 at 15 days or more. TEVAR performed at 15 days or more was independently associated with lower in-hospital/30-day mortality (odds ratio, 0.38; P = .0388) and improved 1-year survival. Postoperative stroke was associated with earlier repair (0-2 days). There was no association of timing of repair with spinal cord ischemia, retrograde type A dissection or reintervention.

CONCLUSIONS

TEVAR for TBAD with HRF delayed at least 15 days from symptom onset is associated with improved survival, supporting the theory that it is best to delay TEVAR until the subacute phase. Additionally, TEVAR delayed at least 3 days is associated with a decrease in stroke. Having more than one HRF was not associated statistically with worse outcomes. Because the classification of HRF is relatively new and without guidelines for repair, this study highlights the risks of early intervention for HRF and suggests that these patients seem to benefit from at least a short stabilization period before TEVAR.

Impact of Frailty on Postoperative Outcomes in Patients undergoing TransCarotid Artery Revascularization (TCAR)

BACKGROUND

Frailty is a clinical syndrome characterized by reduction in metabolic reserves leading to increased susceptibility to adverse outcomes following invasive surgical interventions. The 5-item modified frailty index (mFI-5) validated in prior studies has shown high predictive accuracy for all surgical specialties including vascular procedures. In this study we aim to utilize the mFI-5 to predict outcomes in Transcarotid Revascularization (TCAR).

METHODS

All patient who underwent TCAR from November 2016 to April 2021 in the Vascular Quality Initiative (VQI) Database were included. The mFI-5 was calculated as a cumulative score divided by 5 with 1 point each for poor functional status, presence of diabetes, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), and hypertension. Patients were stratified into two groups based on prior studies: low mFI-5 (0.6) and high (≥0.6). Primary outcomes included in-hospital death, extended length of postoperative stay (> 1 day), and non-home discharge. Secondary outcomes included in-hospital stroke, transient ischemic attack (TIA), myocardial infarction (MI), and composite endpoint of stroke/death, stroke/TIA and stroke/death/MI. Univariate and multivariable logistic regression were used to assess the association between mFI-5 and postoperative outcomes. Secondary analysis stratified by symptomatic status was performed.

RESULTS

Out of the 17,983 patients who underwent TCAR, 4526(25.2%) had mFI-5 score of ≥0.6 and considered clinically frail. Compared to the non-frail group, frail patients were more likely to be female (38.7% vs 35.6%, p<0.001), have poor functional status (43.6 vs 8.3%, p<0.001), and present with significant comorbidities including diabetes (75.3% vs 26.1%, p<0.001), hypertension (98.9% vs 88.5%, p<0.001), CHF (52.2% vs 5.6, p<0.001), and COPD (60.3% vs 14.2%, p<0.001). They were also more likely to be active smokers (25.4% vs 20.4%, p<0.001) and symptomatic prior to intervention (28.7% vs 25.3%, p<0.001). On univariate analysis, frail patients were at significantly higher risk to experience adverse outcomes including in-hospital mortality, TIA, MI, stroke/death, stroke/TIA, stroke/death/MI, discharge to non-home facility, and extended LOS. After adjusting for potential confounders, frail patients remained at significantly higher risk of in-hospital mortality [aOR 2.26(1.41,3.61), p=0.001], TIA [aOR 1.65(1.08, 2.54), p=0.040], non-home discharge [aOR 1.99(1.71,2.32) p<0.001], and extended LOS [aOR 1.41(1.27, 1.55) p<0.001]. On further stratified analysis based on symptomatic status, the increased risk of stroke/death, TIA, and death was observed only in symptomatic patients.

CONCLUSION

Modified Frailty Index is a reliable tool that can be used to identify high risk patients for TCAR prior to intervention. This could help vascular surgeons, patients, and families in informed decision making to further optimize perioperative care and medical management in frail patients.

Lower AM-PAC 6-Clicks Basic Mobility Score Predicts Discharge to a Postacute Care Facility Among Patients in Cardiac Intensive Care Units

OBJECTIVE

The objective of this study was to determine the ability of the Activity Measure for Post-Acute Care "6-Clicks" Basic Mobility Short Form to predict patient discharge destination (home vs postacute care [PAC] facility) from the cardiac intensive care unit (ICU), including patients from the cardiothoracic surgical ICU and coronary care unit.

METHODS

This retrospective cohort study utilized electronic medical records of patients in cardiac ICU (n = 359) in an academic teaching hospital in the southeastern region of United States from September 1, 2017, through August 31, 2018.

RESULTS

The median interquartile range age of the sample was 68 years (75-60), 55% were men, the median interquartile range 6-Clicks score was 16 (20-12) at the physical therapist evaluation, and 79% of the patients were discharged to home. Higher score on 6-Clicks indicates improved function. A prediction model was constructed based on a machine learning approach using a classification tree. The classification tree was constructed and evaluated by dividing the sample into a train-test split using the Leave-One-Out cross-validation approach. The classification tree split the data into 4 distinct groups along with their predicted outcomes. Patients with a 6-Clicks score >15.5 and a score between 11.5 and 15.5 with primary insurance other than Medicare were discharged to home. Patients with a 6-Clicks score between 11.5 and 15.5 with Medicare insurance and those with a score ≤11.5 were discharged to a PAC facility.

CONCLUSION

Patients with lower 6-Clicks scores were more likely to be discharged to a PAC facility. Patients without Medicare insurance had to be significantly lower functioning, as indicated by lower 6-Clicks scores for PAC facility placement than those with Medicare insurance.

IMPACT

The ability of 6-Clicks along with primary insurance to determine discharge destination allows for early discharge planning from cardiac ICUs.

Non-home discharge after cardiac surgery in Australia and New Zealand: a cross-sectional study

OBJECTIVE

To determine the proportion of patients surviving their cardiac surgery who experienced non-home discharge (NHD) over a 16-year period in Australia and New Zealand (ANZ).

DESIGN

Retrospective, multicentre, cross-sectional study over the time period 01 January 2004 to 31 December 2019.

SETTING

Adult patients who underwent cardiac surgery from the Australia New Zealand Intensive Care Society Adult Patient Database (APD).

PARTICIPANTS

Adult patients (age 18 and above) who underwent index coronary artery bypass grafting, cardiac valve surgery or combined valve/coronary surgery.

EXPOSURE

The primary exposure variable was the calendar year during the which the index surgery was performed.

OUTCOME

The primary outcome was NHD after the index surgery. NHD included discharge to locations such as nursing home, chronic care facility, rehabilitation and palliative care.

RESULTS

We analysed 252 924 index cardiac surgical admissions from 101 discrete sites with a median age of 68 years (IQR 60-76), of which 74.2% (187 662 out of 252 920) were males. Of these, 4302 (1.7%) patients died in hospital and 213 011 (84.2%) were discharged home, 18 010 (7.1%) were transferred to another hospital and 17 601 (7%) experienced NHD. In Australia, 14 457 (6.4%) of patients progressed to NHD, compared with 3144 (11.7%) in New Zealand. The rate of NHD increased significantly over time (adjusted OR per year=1.06, 95% CI, 1.06 to 1.07, p<0.001). Increasing age, female sex, non-elective surgery, surgery type and Acute Physiology and Chronic Health Evaluation III Score were all associated with significant increase in NHD.

CONCLUSIONS

There was significant increase in NHD after cardiac surgery over time in ANZ. This has significant clinical relevance for informed consent discussions between healthcare providers and patients, and for healthcare services planning.

Meaningful Patient-centered Outcomes 1 Year Following Cardiac Surgery

OBJECTIVE

To evaluate meaningful, patient-centered outcomes including alive-at-home status and patient-reported quality of life 1 year after cardiac surgery.

BACKGROUND

Long-term patient-reported quality of life after cardiac surgery is not well understood. Current operative risk models and quality metrics focus on short-term outcomes.

METHODS

In this combined retrospective/prospective study, cardiac surgery patients at an academic institution (2014-2015) were followed to obtain vital status, living location, and patient-reported outcomes (PROs) at 1 year using the NIH Patient-Reported Outcomes Measurement Information System (PROMIS). We assessed the impact of cardiac surgery, discharge location, and Society of Thoracic Surgeons perioperative predicted risk of morbidity or mortality on 1-year outcomes.

RESULTS

A total of 782 patients were enrolled; 84.1% (658/782) were alive-at-home at 1 year. One-year PROMIS scores were global physical health (GPH) = 48.8 ± 10.2, global mental health (GMH) = 51.2 ± 9.6, and physical functioning (PF) = 45.5 ± 10.2 (general population reference = 50 ± 10). All 3 PROMIS domains at 1 year were significantly higher compared with preoperative scores (GPH: 41.7 ± 8.5, GMH: 46.9 ± 7.9, PF: 39.6 ± 9.0; all P < 0.001). Eighty-two percent of patients discharged to a facility were alive-at-home at 1 year. These patients, however, had significantly lower 1-year scores (difference: GPH = -5.1, GMH = -5.1, PF = -7.9; all P < 0.001). Higher Society of Thoracic Surgeons perioperative predicted risk was associated with significantly lower PRO at 1 year (P < 0.001).

CONCLUSIONS

Cardiac surgery results in improved PROMIS scores at 1 year, whereas discharge to a facility and increasing perioperative risk correlate with worse long-term PRO. One-year alive-at-home status and 1-year PRO are meaningful, patient-centered metrics that help define long-term quality and the benefit of cardiac surgery.

Discharge Prediction for Patients Undergoing Inpatient Surgery: Development and validation of the DEPENDENSE score

BACKGROUND

A substantial proportion of patients undergoing inpatient surgery each year is at risk for postoperative institutionalization and loss of independence. Reliable individualized preoperative prediction of adverse discharge can facilitate advanced care planning and shared decision making.

METHODS

Using hospital registry data from previously home-dwelling adults undergoing inpatient surgery, we retrospectively developed and externally validated a score predicting adverse discharge. Multivariable logistic regression analysis and bootstrapping were used to develop the score. Adverse discharge was defined as in-hospital mortality or discharge to a skilled nursing facility. The model was subsequently externally validated in a cohort of patients from an independent hospital.

RESULTS

In total, 106 164 patients in the development cohort and 92 962 patients in the validation cohort were included, of which 16 624 (15.7%) and 7717 (8.3%) patients experienced adverse discharge, respectively. The model was predictive of adverse discharge with an area under the receiver operating characteristic curve (AUC) of 0.87 (95% CI 0.87-0.88) in the development cohort and an AUC of 0.86 (95% CI 0.86-0.87) in the validation cohort.

CONCLUSION

Using preoperatively available data, we developed and validated a prediction instrument for adverse discharge following inpatient surgery. Reliable prediction of this patient centered outcome can facilitate individualized operative planning to maximize value of care.

Evaluation of Factors Associated with, and Outcomes for Patients with Nonhome Discharge Destinations Following Carotid Endarterectomy

INTRODUCTION

Following a carotid endarterectomy (CEA) procedure, patients are discharged to their homes or other locations than home such as an acute care facility or skilled nursing facility based on their functional status and level of medical attention needed. Decision-making for discharge destination following a CEA to home or nonhome locations is important due to the differences in survival and postoperative complications. While primary outcomes such as mortality and occurrence of stroke following CEA have been extensively studied, there is a paucity of information characterizing outcomes of discharge destination and the factors associated. The purpose of this study was to explore the factors associated with discharge to nonhome destinations after CEA, and outcomes after discharge.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, we identified patients who underwent CEA from 2011 to 2018. Patients were divided into two groups based on their discharge destination (home versus nonhome). Univariate and multivariate analysis were performed for preoperative and intraoperative factors associated with different discharge destinations. Postoperative complications associated with discharge to nonhome destinations were analyzed and mortality after discharge from hospital was compared between the 2 groups.

RESULTS

A total of 25,094 patients met the criteria for inclusion in the study, of which 39% were females and 61% were males; median age was 71 years. Twenty four thousand one hundred twenty-five patients (93.13%) were discharged to home (Group I) and 1,779 (6.87%) were discharged to nonhome destinations (Group II). Following preoperative and intraoperative factors were associated with discharge to nonhome locations: older age, diabetes mellitus, functional independent status, transfer from other hospitals, symptomatic status, need for preoperative blood transfusions, severe ipsilateral carotid stenosis, elective CEA, need for intraoperative shunt and general anesthesia (all P< 0.05). Following postoperative complications had statistically significant association with discharge to nonhome destinations: postoperative blood transfusion, pneumonia, unplanned intubation, longer than 48 hours on ventilator, development of stroke, myocardial infarction, deep vein thrombosis, and sepsis (all P< 0.05). Mortality after discharge from hospital was 0.39% (n = 100). Mortality among those who were discharged to home was 0.29% vs. 1.63% for those who were discharged to nonhome locations (P< 0.05).

CONCLUSIONS

Majority of the patients after CEA are discharged back to their homes. This study identifies the factors which predispose patients discharged to locations, other than home. Patients who are not discharged home have higher mortality as compared to those who are discharged to their homes.

Incidence and Severity of Depression Among Recovered African Americans with COVID-19-Associated Respiratory Failure

Background

Coronavirus disease (COVID-19) disproportionately affects African Americans, and they tend to experience more severe course and adverse outcomes. Using a simple and validated instrument of depression screening, we evaluated the incidence and severity of major depression among African American patients within 90 days of recovery from severe COVID-19-associated respiratory failure.

Methods

African American patients hospitalized and treated with invasive mechanical ventilation for COVID-19-associated respiratory failure in the intensive care unit (ICU) of Grady Memorial Hospital, Atlanta, between April 1, 2020, and June 30, 2020, were screened for depression within 90 days of hospital discharge using the validated patient health questionnaires (PHQ-2) and PHQ-9.

Results

A total of 73 patients completed the questionnaire. The median age was 52.5 years [IQR 44–65] and 65% were males. The most common comorbidities were hypertension (66%) and diabetes mellitus (51%). Forty-four percent of the patients had a diagnosis of major depressive disorder (MDD) based on their PHQ-9 questionnaire responses. The incidence of MDD was higher among females (69%, n=18/26) compared to males (29%, n=14/47), in patients > 75 years (66%) and those with multiple comorbidities (45%). Eighteen percent of the patients had moderate depression, while 15% and 22% had moderately severe and severe depression, respectively. Only 26% (n=7/27) of eligible patients were receiving treatment for depression at the time of this survey.

Conclusion

The incidence of depression in a cohort of African American patients without prior psychiatric conditions who recovered from severe COVID-19 infection was 44%. More than 70% of these patients were not receiving treatment for depression.

Effects of the Level and Duration of Mobilization Therapy in the Surgical ICU on the Loss of the Ability to Live Independently: An International Prospective Cohort Study

OBJECTIVES

It is unclear whether early mobilization in the surgical ICU helps improve patients' functional recovery to a level that enables independent living. We assessed dose of mobilization (level + duration). We tested the research hypotheses that dose of mobilization predicts adverse discharge and that both duration of mobilization and maximum mobilization level predict adverse discharge.

DESIGN

International, prospective cohort study.

SETTING

Study conducted in five surgical ICUs at four different institutions.

PATIENTS

One hundred fifty patients who were functionally independent before admission (Barthel Index ≥ 70) and who were expected to stay in the ICU for greater than or equal to 72 hours.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Mobilization was quantified daily, and treatments from all healthcare providers were included. We developed and used the Mobilization Quantification Score that quantifies both level and duration of mobilization. We assessed the association between the dose of mobilization (level + duration; exposure) and adverse discharge disposition (loss of the ability to live independently; primary outcome). There was wide variability in the dose of mobilization across centers and patients, which could not be explained by patients' comorbidity or disease severity. Dose of mobilization was associated with reduced risk of adverse discharge (adjusted odds ratio, 0.21; 95%CI, 0.09-0.50; p < 0.001). Both level and duration explained variance of adverse discharge (adjusted odds ratio, 0.28; 95% CI, 0.12-0.65; p = 0.003; adjusted odds ratio, 0.14; 95% CI, 0.06-0.36; p < 0.001, respectively). Duration compared with the level of mobilization tended to explain more variance in adverse discharge (area under the curve duration 0.73; 95% CI, 0.64-0.82; area under the curve mobilization level 0.68; 95% CI, 0.58-0.77; p = 0.10).

CONCLUSIONS

We observed wide variability in dose of mobilization treatment applied, which could not be explained by patients' comorbidity or disease severity. High dose of mobilization is an independent predictor of patients' ability to live independently after discharge. Duration of mobilization sessions should be taken into account in future quality improvement and research projects.

"Keep Your Move in the Tube" safely increases discharge home following cardiac surgery

BACKGROUND

Restrictive sternal precautions intended to prevent cardiac surgery patients from damaging healing sternotomies lack supporting evidence and may decrease independence and increase postacute care utilization. Data regarding the impact of alternative approaches on safety and outcomes are needed to guide evidence-based best practices.

OBJECTIVE

To examine whether an approach allowing greater freedom during activities of daily living than permitted under commonly used restrictive sternal precautions can safely decrease postacute care utilization.

DESIGN

Before-and-after study, using propensity score adjustment to account for differences in patient clinical and demographic characteristics, surgery type, and surgeon.

SETTING

600-bed acute care hospital.

INTERVENTION

Beginning March 2016, the acute care hospital replaced traditional weight- and time-based precautions given to patients who underwent median sternotomy with the "Keep Your Move in the Tube" (KMIT) approach for mindfully performing movements involved in the activities of daily living, guided by pain.

MAIN OUTCOME MEASURES

The study compared sternal wound complications, discharge disposition, 30-day readmission, and functional status between consecutive cardiac surgery patients with "independent" or "modified independent" preoperative functional status who underwent median sternotomy in the 1.5 years before (n = 627, standard precautions group) and after (n = 477, KMIT group) KMIT implementation.

RESULTS

The odds of discharge to home, versus to inpatient rehabilitation or skilled nursing facility, were ~3 times higher for KMIT than standard precautions patients (risk-adjusted odds ratio [rOR], 95% confidence interval [CI] = 2.90, 1.95-4.32, and 3.03, 1.57-5.86, respectively). KMIT patients also had significantly higher odds of demonstrating "independent" or "modified independent" functional status on final inpatient physical therapy treatment for bed mobility (rOR, 95% CI = 7.51, 5.48-10.30) and transfers (rOR, 95% CI = 3.40, 2.62-4.42). No significant difference was observed in sternal wound complications (in-hospital or causing readmission) (rOR, 95% CI = 1.27, 0.52-3.09) or all-cause 30-day readmissions (rOR, 95% CI = 0.55, 0.23-1.33).

CONCLUSIONS

KMIT increases discharge-to-home for cardiac surgery patients without increasing risk for adverse events and reducing utilization of expensive institutional postacute care.

Feedback Training Improves Compliance with Sternal Precaution Guidelines during Functional Mobility: Implications for Optimizing Recovery in Older Patients after Median Sternotomy

Patients often need to use their arms to assist with functional activities, but after open heart surgery, pushing with the arms is limited to <10 lb (4.5 kg) to help minimize force across the healing sternum. The main purposes of this study were to determine if older patients (>60 years old) (1) accurately estimated upper extremity (UE) weight bearing force of 10 lb or less and (2) if feedback training improved their ability to limit UE force and pectoralis major muscle contraction during functional activities. An instrumented walker was used to measure UE weight bearing force, and electromyography was used to measure pectoralis major muscle activity simultaneously during 4 functional mobility tasks. After baseline testing, healthy older subjects (n = 30) completed a brief session of visual and auditory concurrent feedback training. Results showed that the self-selected UE force was >10 lb for all tasks (20.0-39.7 lb [9.1-18.0 kg]), but after feedback training, it was significantly reduced (10.6-21.3 lb [4.8-9.7 kg]). During most trials (92%), study participants used >12 lb (5.5 kg) of arm weight bearing force. Pectoralis major muscle peak electromyography activity was <23% of maximal voluntary isometric contraction and was reduced (9.8-14.9%) after feedback training. Older patients may not be able to accurately estimate UE arm force used during weight bearing activities, and visual and auditory feedback improves accuracy and also modulation of pectoralis major muscle activation. Results suggest that an instrumented walker and feedback training could be clinically useful for older patients recovering from open heart surgery.

Depression Predicts Non-Home Discharge After Abdominal Aortic Aneurysm Repair

BACKGROUND

Mental health's impact on vascular surgical patients has long been overlooked. While outside the expertise of most surgeons, understanding the role that depression plays in the postoperative course could provide additional insight into opportunities to improve surgical outcomes and healthcare value. Additionally, non-home discharge (NHD) to a rehabilitation or skilled nursing facility after surgery is associated with impaired quality of life and higher postdischarge complications, readmissions, and mortality. We hypothesized that depression would be associated with an increased risk for NHD following abdominal aortic aneurysm (AAA) repair.

METHODS

Nonruptured AAA repair cases were identified from the National Inpatient Sample (NIS) using ICD-9 codes between 2005 and 2014. Depression, comorbidities, postoperative complications, and discharge destination were evaluated using statistical tests as appropriate to the data. A hierarchical multivariable logistic regression controlling for hospital level variation was used to examine the independent association between depression, and the primary outcome of NHD controlling for median income and confounders meeting P < 0.05 on univariate analysis.

RESULTS

There were 99,934 total cases analyzed, of which 4,755 (4.8%) were diagnosed with depression and 10,618 (11.9%) required NHD. Patients with depression were younger, more likely to be women, white, have diabetes, chronic obstructive pulmonary disease, hypertension, tobacco use, and more likely to experience a postoperative complication. On adjusted multivariable analysis, patients with depression were more likely to require NHD (odds ratio [OR] 1.87, 95% confidence interval [CI]: 1.68-2.08, c-statistic = 0.82). On stratified analysis by operative approach, depression had a larger effect estimate in endovascular repair (OR 2.19; 95% CI: 1.90-2.52) versus open repair (OR 1.60; 95% CI: 1.38-1.87).

CONCLUSIONS

In a nationally representative sample, patients with depression were more likely to require NHD after AAA repair. This study highlights the importance that depression plays in postoperative outcomes after AAA repair. Furthermore, addressing mental health preoperatively has the potential to improve outcomes in patients undergoing AAA repair.

Patients with depression are less likely to go home after critical limb revascularization

BACKGROUND

Although often overlooked during the preoperative evaluation, recent evidence has suggested that depression in patients with peripheral artery disease is associated with increased postoperative complications, including decreased primary and secondary patency after revascularization and an increased risk of major amputation and mortality. Postoperative nonhome discharge (NHD) is an important outcome for patients and has also been associated with other adverse outcomes; however, the effect that depression has on NHD after vascular surgery has remained unexplored. We hypothesized that depression would be associated with an increased risk of NHD after revascularization for chronic limb threatening ischemia (CLTI).

METHODS

Endovascular, open, and hybrid (combined open and endovascular) cases of revascularization for CLTI were identified from the 2012 to 2014 National (Nationwide) Inpatient Sample. CLTI, diagnoses of depression, and medical comorbidities were defined using the corresponding International Classification of Diseases, Ninth Revision, Clinical Modification codes. A hierarchical multivariable binary logistic regression controlling for hospital level variation and for confounders meeting P <.01 on bivariate analysis was used to examine the association between depression and NHD. A sensitivity analysis after coarsened exact matching for baseline characteristics that differed between the two groups was performed to reduce any imbalance.

RESULTS

A total of 64,817 cases were identified, of which 5472 (8.4%) included a diagnosis of depression and 16,524 (25.5%) NHD. The patients with depression were younger and more likely to be women and white, have multiple comorbidities and a nonelective admission, and experience a postoperative complication (P <.05). On unadjusted analyses, patients with depression had an 8% absolute increased risk of requiring NHD (32.1% vs 24.9%; P <.001). On multivariable analysis, patients with depression had an increased odds for NHD (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.40-1.61; c-statistic, 0.81) compared with those without depression. After stratification by operative approach, depression had a larger effect estimate in endovascular revascularization (OR, 1.57; 95% CI, 1.42-1.74) compared with open (OR, 1.45; 95% CI, 1.30-1.62). A test for interaction between depression and gender identified that men with depression had greater odds of NHD compared with women with depression (OR, 1.68; 95% CI, 1.51-1.88; vs OR, 1.37; 95% CI, 1.25-1.51; interaction P <.01). A sensitivity analysis after coarsened exact matching confirmed these findings.

CONCLUSIONS

To the best of our knowledge, the present study is the first to identify an association between depression and NHD after revascularization for CLTI. These results provide further evidence of the negative effects that comorbid depression has on patients undergoing revascularization for CLTI. Future studies should examine whether treating depression can improve the outcomes in this patient population.

Sources of Hospital Variation in Postacute Care Spending After Cardiac Surgery

BACKGROUND

Postacute care is a major driver of cardiac surgical episode spending, but the sources of variation in spending have not been explored. The objective of this study was to identify sources of variation in postacute care spending within 90-days of discharge following coronary artery bypass grafting (CABG) and aortic valve replacement (AVR) and the relationship between postacute care spending and other postdischarge utilization.

METHODS AND RESULTS

A retrospective analysis was conducted of public and private administrative claims for Michigan residents insured by Medicare fee-for-service and Blue Cross Blue Shield of Michigan/Blue Care Network commercial and Medicare Advantage plans undergoing CABG (n=11 208) or AVR (n=6122) in 33 nonfederal acute care Michigan hospitals between January 1, 2015 and December 31, 2018. Postacute care use was present in 9662 (86.2%) CABG episodes and 4242 (69.3%) AVR episodes, with respective mean (SD) 90-day spending of $4398±$6124 and $3465±$5759. Across hospitals, mean postacute care spending ranged from $3280 to $8186 for CABG and $2246 to $7710 for AVR. Inpatient rehabilitation and skilled nursing facility care accounted for over 80% of the variation spending between low and high postacute care spending hospitals. At the hospital-level, postacute care spending was modestly correlated across procedures and payers. Spending associated with readmissions, emergency department visits, and outpatient facility care was significantly different between low and high postacute care spending hospitals in CABG and AVR episodes.

CONCLUSIONS

There was wide hospital variation in postacute care spending after cardiac surgery, which was primarily driven by differential use and intensity in facility-based postacute care. Optimizing facility-based postacute care after cardiac surgery offers unique opportunities to reduce potentially unwarranted care variation.

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.

A novel preoperative risk score for nonhome discharge after elective thoracic endovascular aortic repair

BACKGROUND

Nonhome discharge (NHD) to a rehabilitation or skilled nursing facility after vascular surgery is poorly described despite its large impact on patients. Understanding postsurgical NHD risk is essential to providing adequate preoperative counseling and shared decision making, particularly for elective surgeries. We aimed to identify independent predictors of NHD after elective thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysms (TAA) and to create a clinically useful preoperative risk score.

METHODS

Elective TEVAR cases for descending TAA were queried from the Society for Vascular Surgery Vascular Quality Initiative from 2014 to 2018. A risk score was created by splitting the dataset into two-thirds for model 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. This score was then cross-validated and model performance assessed.

RESULTS

Overall, 1469 patients were included and 213 (14.5%) required NHD. At baseline, patients who required NHD were more likely to be ≥80 years old (35.2% vs 19.4%), female (58.7% vs 40.6%), functionally dependent (42.3% vs 24.0%), and anemic (46.5% vs 27.8%), and to have chronic obstructive pulmonary disease (41.3% vs 33.4%), congestive heart failure (18.8% vs 11.1%), and American Society of Anesthesiologists class ≥4 (51.6% vs 39.8%; all P < .05). Multivariable analysis in the development group identified independent predictors of NHD that were used to create an 18-point risk score. Patients were stratified into three groups based upon their risk score: low risk (0-7 points; n = 563) with an NHD rate of 4.3%, moderate risk (8-11 points; n = 701) with an NHD rate of 17.0%, and high risk (≥12 points; n = 205) with an NHD rate of 34.2%. The risk score had good predictive ability with a c-statistic of 0.75 for model development and a c-statistic of 0.72 in the validation dataset.

CONCLUSIONS

This novel risk score can predict NHD after TEVAR for TAA using characteristics that can be identified preoperatively. The use of this score may allow for improved risk assessment, preoperative counseling, and shared decision making.

Development of an Instrument for Preoperative Prediction of Adverse Discharge in Patients Scheduled for Cardiac Surgery

OBJECTIVE

Inability of home discharge occurs in nearly a third of patients undergoing cardiac surgery and is associated with increased mortality. The authors aimed to evaluate the incidence and risk factors for adverse discharge disposition (ADD) after cardiac surgery and develop a prediction tool for preoperative risk assessment.

DESIGN

This retrospective cohort study included adult patients undergoing cardiac surgery between 2010 and 2018. The primary outcome was ADD, defined as in-hospital mortality, discharge to a skilled nursing facility, or transfer to a long-term care hospital. The authors created a prediction tool using stepwise backward logistic regression and used 5-fold and leave-one-out cross-validation.

SETTING

University hospital network.

PARTICIPANTS

Adult patients living at home prior to surgery, who underwent coronary artery bypass grafting and/or valve procedures at the authors' institution.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A total of 3,760 patients were included in the final study cohort. The observed rate of ADD was 33.3%. The prediction model showed good discrimination and accuracy, with C-statistic of 0.78 (95% confidence interval [CI] 0.76-0.79) and unmodified Brier score of 0.177 (reliability 0.001). The final model comprised 14 predictors. Patients who experienced ADD were more likely to be older, of female sex, to have had higher length of hospital stay prior to surgery, and to have undergone emergency surgery.

CONCLUSIONS

The authors present an instrument for prediction of loss of the ability to live independently in patients undergoing cardiac surgery. The authors' score may be useful in identifying high-risk patients such that earlier coordination of care can be initiated in this vulnerable patient population.

Safety of Major Abdominal Operations in the Elderly: A Study of Geriatric-Specific Determinants of Health

BACKGROUND

Preoperative assessment of geriatric-specific determinants of health may enhance perioperative risk stratification among elderly patients. This study examines effects of geriatric-specific variables on postoperative outcomes in patients undergoing elective major abdominal operations.

METHODS

Patients included in the ACS NSQIP pilot Geriatric Surgery Research File program who underwent elective pancreatic, liver, and colorectal operations between 2014 and 2016 were examined. Multivariable analyses were performed to evaluate associations between patient-specific geriatric variables and risk of death, morbidity, readmission, and discharge destination.

RESULTS

A total of 4165 patients were included. Patients ≥85 years were more likely to die, experience postoperative morbidity, and be discharged to a facility (all p ≤ 0.039) than younger patients. Preoperatively, patients ≥85 years were more likely to use a mobility aid, have a prior fall, have consent signed by a surrogate, and to live alone at home prior to operation (all p < 0.001). After adjustment for ACS NSQIP-estimated probabilities of morbidity or mortality, no geriatric-specific preoperative risk factors were significantly associated with increased risk of death or complications in any age group (all p > 0.055). Patients 75-84 and ≥85 years were more likely to be discharged to facility (OR 2.33 and 4.75, respectively, both p < 0.001) compared to patients 65-74 years. All geriatric-specific variables: use of mobility aid, living alone, consent signed by a surrogate, and fall history, were significantly associated with discharge to a facility (all p ≤ 0.001).

CONCLUSIONS

After adjusting for comorbid conditions, geriatric-specific variables are not associated with postoperative mortality and morbidity among elderly patients; however, geriatric-specific variables are significantly associated with discharge to a facility.

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.

Comparison of Surgeon Assessment to Frailty Measurement in Abdominal Aortic Aneurysm Repair

BACKGROUND

Endovascular abdominal aortic aneurysm repair (EVAR) allows us to intervene on patients otherwise considered poor candidates for open repair. Despite its importance in determining operative approach, no comparison has been made between the subjective "eyeball test" and an objective measurement of preoperative frailty for EVAR patients.

MATERIALS AND METHODS

Patients undergoing elective EVAR were identified in the Vascular Quality Initiative (VQI) database (2003-2017). Patients were classified "unfit" based on a surgeon-reported variable. Frailty was defined using the VQI-derived Risk Analysis Index, which includes sex, age, BMI, renal failure, congestive heart failure, dyspnea, preoperative ambulation, and functional status. The association between fitness and/or frailty and adverse outcomes was determined by logistic regression.

RESULTS

A total of 11,694 patients undergoing elective EVAR were included of which only 18.1% were "unfit," whereas 34.6% were "frail" and overall 43.6% "unfit or frail." Patients deemed "unfit" or "frail" had significantly increased odds of mortality, complications, and nonhome discharge (P < 0.001), and both frailty and unfitness generated negative predictive values for these outcomes greater than 93%. In adjusted logistic regression, the addition of objective frailty significantly improved model performance in predicting nonhome discharge (C-statistic 0.65 versus 0.71, P < 0.001) and complications (0.59 versus 0.61, P = 0.01), but similarly predicted mortality (0.74 versus 0.73, P = 0.99).

CONCLUSIONS

Preoperative frailty assessment provides a useful objective measure of risk stratification as an adjunct to a physician's clinical intuition. The addition of frailty expands the pool of high-risk patients who are more likely to experience adverse postoperative events after elective EVAR and may benefit from uniquely tailored perioperative interventions.

Discharge disposition of older patients undergoing trans-catheter aortic valve replacement and its impact on survival

BACKGROUND

Patients undergoing transcatheter aortic valve replacement (TAVR) are likely to be discharged to a location other than home. We aimed to assess the association between discharge disposition after TAVR and patient survival at 1 year.

METHODS

Patients admitted from home and survived till discharge after TAVR were divided into two groups based on discharge disposition (home discharge vs. non-home discharge). Pre-operative factors predicting the odds of not being discharged home were identified by using multivariable logistic regression analysis. Study patients were matched one-to-one via a propensity scoring method. Differences in procedural outcomes were compared. Survival of both unmatched and matched pairs was evaluated by using the Kaplan-Meier method with the Kleine-Moesch-Berger stratified log-rank test.

RESULTS

Out of 1,160 TAVR patients, 851 were admitted from home and survived till discharge. The incidence non-home discharge was 19% (n = 159). Factors that were significantly associated with non-home discharge were older age, non-transfemoral approach, female sex, frailty status, history of chronic lung disease, pacemaker placement and insulin-dependent diabetes mellitus. One-to-one propensity score matching resulted in 141 patient pairs with similar age, operative risk, frailty and functional status. At 1-year follow-up, all-cause mortality rates were significantly higher in the non-home group than their home counterparts (18% vs. 3%, P = 0.006; stratified log rank test: P = 0.006).

CONCLUSIONS

A considerable number of TAVR patients are discharged to a location other than home after the procedure. Not being discharged home after TAVR is associated with a high mortality risk at 1 year.

Association Between Postoperative Pneumonia and 90-Day Episode Payments and Outcomes Among Medicare Beneficiaries Undergoing Cardiac Surgery

Background Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. Our objective was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. Methods and Results Medicare claims were used to identify beneficiaries with episodes of coronary artery bypass grafting (CABG; n=56 728) and valve surgery (n=56 377) across 1045 centers between April 2014 and March 2015. Using a published diagnosis code-based algorithm, we identified pneumonia in 6.4% CABG episodes and 6.6% of valve surgery episodes. We compared price-standardized 90-day episode payments and outcome measures (postoperative length of stay, discharge to postacute care, mortality, and readmission) between beneficiaries with and without pneumonia using hierarchical regression models, adjusting for patient factors and hospital random effects. Pneumonia was associated with 24.5% higher episode payments for CABG ($46 723 versus $37 496; P<0.001) and 26.5% higher episode payments for valve surgery ($61 544 versus $48 549; P<0.001). For both cohorts, pneumonia was significantly associated with longer postoperative length of stay (CABG: +4.1 days, valve: +5.6 days), more frequent discharge to postacute care (CABG: odds ratio [OR]=1.99, valve: OR=2.17), and higher rates of 30-day mortality (CABG: OR=2.42, valve: OR=2.57) and 90-day readmission (CABG: OR=1.20, valve: OR=1.25), all P<0.001. We compared episode payments and outcomes across terciles of pneumonia rates and found that high pneumonia rate hospitals had higher episode payments and poorer outcomes compared with episodes at low pneumonia rate hospitals in both CABG and valve surgery cohorts. Conclusions Postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level. Future work should examine whether reducing pneumonia after cardiac surgery reduces episode spending and improves outcomes, which could facilitate hospital success in value-based reimbursement programs.

Variation in center-level frailty burden and the impact of frailty on long-term survival in patients undergoing elective repair for abdominal aortic aneurysms

OBJECTIVE

Frailty is increasingly recognized as a key determinant in predicting postoperative outcomes. Centers that see more frail patients may not be captured in risk adjustment, potentially accounting for poorer outcomes in hospital comparisons. We aimed to (1) determine the effect of frailty on long-term mortality in patients undergoing elective abdominal aortic aneurysm (AAA) repair and (2) evaluate the variability in frailty burden among centers in the Vascular Quality Initiative (VQI) database.

METHODS

Patients undergoing elective open and endovascular AAA repair (2003-2017) were identified, and those with complete data on component variables of the VQI-derived Risk Analysis Index (VQI-RAI) and centers with ≥10 AAA repairs were included. VQI-RAI characteristics are sex, age, body mass index, renal failure, congestive heart failure, dyspnea, preoperative ambulation, and functional status. Frailty was defined as VQI-RAI ≥35 based on prior work in surgical patients using other quality improvement databases. This corresponds to the top 12% of patients at risk in the VQI. Center-level VQI-RAI differences were assessed by analysis of variance test. Relationships between frailty and survival were compared by Kaplan-Meier analysis and the log-rank test for open and endovascular procedures. Multivariable hierarchical Cox proportional hazards regression models were calculated with random intercepts for center, controlling for frailty, race, insurance, AAA diameter, procedure type, AAA case mix, and year.

RESULTS

A total of 15,803 patients from 185 centers were included. Mean VQI-RAI scores were 27.6 (standard deviation, 5.9; range, 4-56) and varied significantly across centers (F = 2.41, P < .001). The percentage of frail patients per center ranged from 0% to 40.0%. In multivariable analysis, frailty was independently associated with long-term mortality (hazard ratio, 2.88; 95% confidence interval, 2.6-3.2) after accounting for covariates and center-level variance. Open AAA repair was not associated with long-term mortality after adjusting for frailty (hazard ratio, 0.98; 95% confidence interval, 0.86-1.13). There was a statistically significant difference in the percentage of frail patients compared with nonfrail patients who were discharged to a rehabilitation facility or nursing home after both open (40.5% vs 17.8%; P < .0001) and endovascular repair (17.7% vs 4.6%; P < .0001).

CONCLUSIONS

There is considerable variability of preoperative frailty among VQI centers performing elective AAA repair. Adjusting for center-level variation, frailty but not procedure type had a significant association with long-term mortality; however, frailty and procedure type were both associated with nonhome discharge. Routine measurement of frailty preoperatively by centers to identify high-risk patients may help mitigate procedural and long-term outcomes and improve shared decision-making regarding AAA repair.

Perspectives of Post-Acute Transition of Care for Cardiac Surgery Patients

Post-acute care (PAC) facilities improve patient recovery, as measured by activities of daily living, rehabilitation, hospital readmission, and survival rates. Seamless transitions between discharge and PAC settings continue to be challenges that hamper patient outcomes, specifically problems with effective communication and coordination between hospitals and PAC facilities at patient discharge, patient adherence and access to cardiac rehabilitation (CR) services, caregiver burden, and the financial impact of care. The objective of this review is to examine existing models of cardiac transitional care, identify major challenges and social factors that affect PAC, and analyze the impact of current transitional care efforts and strategies implemented to improve health outcomes in this patient population. We intend to discuss successful methods to address the following aspects: hospital-PAC linkages, improved discharge planning, caregiver burden, and CR access and utilization through patient-centered programs. Regular home visits by healthcare providers result in decreased hospital readmission rates for patients utilizing home healthcare while improved hospital-PAC linkages reduced hospital readmissions by 25%. We conclude that widespread adoption of improvements in transitional care will play a key role in patient recovery and decrease hospital readmission, morbidity, and mortality.

Emergencies and outcome in invasive out-of-hospital ventilation: An observational study over a 1-year period

OBJECTIVES

The number of ventilated patients is further increasing which leads to an increasing number of patients with weaning failure. In Germany, the treatment of patients with invasive out-of-hospital becomes more and more common. The aim of the study was to observe the outcome, the frequency and character of emergencies of patients with invasive out-of-hospital ventilation.

METHODS

We conducted a prospective study over 1 year. Fifty-nine invasively ventilated patients living either at home or at nursing homes specialized in ventilator medicine were included.

RESULTS

Forty-one (71%) of the patients were living in a nursing home. Chronic obstructive pulmonary disease (COPD) was the most common underlying disease (52.5%). Duration of daily ventilation did not change over the 1-year period. 52.8% of the months went without a documented emergency. The most common emergencies were oxygen desaturation (29.6%), increase of secretion (12.2%) and dyspnea (8.7%). We found no difference in the frequency of emergencies between patients cared for in their own home compared with residential care. Ten patients died during the observation period. Fewer emergencies (P = .02, CI 0.03-0.85) was the only parameter associated with a reduced mortality. Frequency of emergencies as well as survival showed no difference regarding the way patients were cared for.

CONCLUSIONS

In patients with invasive home mechanical ventilation survival for more than 1 year seems to be common. Only the rate of emergencies affected survival.
