Functional status, healthcare utilization, and the costs of liver transplantation.

The Model for End-Stage Liver Disease (MELD) score predicts higher transplant healthcare utilization and costs; however, the independent contribution of functional status towards costs is understudied. The study objective was to evaluate the association between functional status, as measured by Karnofsky Performance Status (KPS), and liver transplant (LT) costs in the first posttransplant year. In a cohort of 598 LT recipients from July 1, 2009 to November 30, 2014, multivariable models assessed associations between KPS and outcomes. LT recipients needing full assistance (KPS 10%-40%) vs being independent (KPS 80%-100%) were more likely to be discharged to a rehabilitation facility after LT (22% vs 3%) and be rehospitalized within the first posttransplant year (78% vs 57%), all P < .001. In adjusted generalized linear models, in addition to MELD (P < .001), factors independently associated with higher 1-year post-LT transplant costs were older age, poor functional status (KPS 10%-40%), living donor LT, pre-LT hemodialysis, and the donor risk index (all P < .001). One-year survival for patients in the top cost decile was 83% vs 93% for the rest of the cohort (log rank P < .001). Functional status is an important determinant of posttransplant resource utilization; therefore, standardized measurements of functional status should be considered to optimize candidate selection and outcomes.

Services Receipt Following Veteran Outpatients' Positive Screen for Homelessness.

INTRODUCTION: The Veterans Health Administration seeks to reduce homelessness among Veterans by identifying, and providing prevention and supportive services to, patients with housing concerns. The objectives of this study were to assess the proportion of Veterans Health Administration patients who received homeless or social work services within 6 months of a positive screen for homelessness or risk in the Veterans Health Administration and the demographic and clinical characteristics that predicted services utilization. METHODS: Data were from a cohort of 27,403 Veteran outpatients who screened positive for homelessness or risk between November 1, 2012 and January 31, 2013. During 2013, AORs were calculated using a mixed-effects logistic regression to estimate the likelihood of patients' receipt of VHA homeless or social work services based on demographic and clinical characteristics. RESULTS: The majority of patients received services within 6 months post-screening; predictors of services utilization varied by gender. Among women, diagnosis of drug abuse and psychosis predicted receipt of services, being unmarried increased the odds of using services among those screening positive for homelessness, and a diagnosis of post-traumatic stress disorder increased the odds of receiving services for at-risk women. Among men, being younger, unmarried, not service-connected/Medicaid-eligible, and having a medical or behavioral health condition predicted receipt of services. CONCLUSIONS: Receipt of housing support services among Veterans post-homelessness screening differs by patient demographic and clinical characteristics. Future research should investigate the role that primary and secondary prevention interventions play in Veterans' resolution of risk for homelessness and experience of homelessness.

Transplantation of "high-risk" donor hearts: Implications for infection.

BACKGROUND: Heart transplantation is the gold-standard treatment for end-stage heart failure. Short- and long-term outcomes have been excellent, but the shortage of organs persists. The number of potential recipients who die while awaiting orthotopic heart transplantation increases yearly. In 2004, the label "high-risk donor" (HRD) was applied, by the United Network for Organ Sharing (UNOS), to any organ donor who met the Centers for Disease Control (CDC) criteria for behavior that put them at high risk of infection. Despite organ shortages, grafts from HRD CDCs are often declined, because of concerns regarding infection. We undertook this study to analyze our extensive experience with orthotopic heart transplantation of grafts from HRD CDCs, and to determine the short- and long-term outcomes associated with recipients of hearts from HRD CDCs, particularly transmission of infection. METHODS: We performed 367 heart transplantations at our center from September 2008 to September 2014, a timeframe during which the HRD CDC labeling had been implemented. Of the total number of orthotopic heart transplantations performed, 55 patients (15%) received organs from HRD CDCs that had known negative serology for human immunodeficiency virus (HIV), hepatitis B, and hepatitis C. We reviewed demographic, perioperative, and short- and long-term outcomes. The recipients of grafts from HRD CDCs were followed closely, with 3- and 12-month surveillance laboratory testing of viral load for HIV, for hepatitis B, and for hepatitis C core- and surface-antigen serology. RESULTS: All 55 patients (72.7% were men) underwent a successful transplantation procedure. One patient was excluded from follow-up analysis because he was re-transplanted within 4 days owing to the posttransplant finding of metastatic lung adenocarcinoma within the donor. Primary etiology of heart failure was ischemic in 18 of the patients. The most common blood type was O positive, in 20 patients (37.1%), followed by A positive, in 19 patients (35.2%). A total of 19 (35.2%) patients were supported with a mechanical assist device before the transplantation. The average allograft ischemic time was 173 ± 96 minutes. The median length of hospital stay was 19.5 days. A low incidence was observed of the postoperative complications of stroke (1.9%), dialysis (3.9%), and complete heart block (3.9%). Kaplan-Meier analysis demonstrated excellent survival, both short-term (1 year; 94%) and long-term (3 years; 80%). Allograft function was excellent at time of discharge with a left ejection fraction of 67.8% ± 7.3%. Only one patient (1.9%) was noted to have hepatitis C seroconversion at 105 days after receiving the transplant. After antiviral treatment, the patient has had undetectable viral loads to date. All other patients had undetectable plasma viral loads of HIV, hepatitis C, and hepatitis B, determined using rigorous testing. CONCLUSIONS: We present the only single-center series on recipients of heart transplants from HRD CDCs. This potential source of suitable donor organs is shown to lead to excellent survival, without an increased incidence of perioperative or postoperative complications. Furthermore, the risk of transmission of infection from donors in this subgroup seems to be minimal.

Race, Rehabilitation, and 30-Day Readmission After Elective Total Knee Arthroplasty.

INTRODUCTION: To examine racial variations in access to postacute care (PAC) and rehabilitation (Rehab) services following elective total knee arthroplasty and whether where patients go after surgery for PAC/Rehab is associated with 30-day readmission to acute care facility. MATERIALS AND METHODS: Sample consisted of 129 522 patients discharged from 169 hospitals in the State of Pennsylvania between fiscal years 2008 and 2012. We used multinomial regression models to assess the relationship between patient race and discharge destination after surgery, for patients aged 18 to 64 years and for those aged 65 and older. We used multivariable (MV) regression and propensity score (PS) approaches to examine the relationship between patient discharge destination after surgery for PAC/Rehab and 30-day readmission, controlling for key individual- and facility-level factors. RESULTS: Lower proportions of younger patients compared to those older than 65 were discharged to inpatient rehabilitation facilities (IRFs; 5.8% vs 12.6%, respectively) and skilled nursing facilities (SNFs; 15.2% vs 32.7%, respectively) compared to home-based Rehab (self-care; 23.3% vs 14.2%, respectively). Compared to whites, African American patients had significantly higher odds of discharge to IRF (age < 65, odds ratio = 2.04; age ≥ 65, odds ratio = 1.64) and to SNF (age < 65, odds ratio = 2.86; age ≥ 65, odds ratio = 2.19) and discharge to home care in patients younger than 65 years (odds ratio = 1.31). The odds of 30-day readmission among patients discharged to an IRF (MV odds ratio = 7.76; PS odds ratio = 8.34) and SNF (MV odds ratio = 2.01; PS odds ratio = 1.83) were significantly higher in comparison to patients discharged home with self-care. CONCLUSION: African American patients with knee replacement are more likely to be discharged to inpatient Rehab settings following surgery. Inpatient Rehab is significantly associated with 30-day readmission to acute care facility.

Demographic characteristics associated with homelessness and risk among female and male veterans accessing VHA outpatient care.

BACKGROUND: This study explored demographic influences on veterans' reports of homelessness or imminent risk of homelessness with a particular focus on gender. METHODS: We analyzed data for a cohort of veterans who responded to the U.S. Department of Veterans Affairs (VA), Veterans Health Administration (VHA) universal screener for homelessness and risk during a 3-month period. Multinomial mixed effects models-stratified by gender-predicted veterans' reports of homelessness or risk based on age, race, marital status, and receipt of VA compensation. FINDINGS: The proportion of positive screens-homelessness or risk-was 2.7% for females and 1.7% for males. Women more likely to report being at risk of homelessness were aged 35 to 54 years, Black, and unmarried; those more likely to experience homelessness were Black and unmarried. Among male veterans, the greatest predictors of both homelessness and risk were Black race and unmarried status. Among both genders, receiving VA disability compensation was associated with lesser odds of being homeless or at risk. CONCLUSIONS: The findings describe the current population of veterans using VHA health care services who may benefit from homelessness prevention or intervention services, identify racial differences in housing stability, and distinguish subpopulations who may be in particular need of intervention. Interventions to address these needs are described.

Disparities in housing status among veterans with general medical, cognitive, and behavioral health conditions.

OBJECTIVE: The study explored disparities in housing status among veterans with general medical, cognitive, and behavioral health conditions. METHODS: Multinomial mixed-effects models estimated the relationship between medical, cognitive, and behavioral health comorbidities and housing instability among veterans enrolled in the Veterans Health Administration (VHA) (N=1,582,125) who responded to the Homelessness Screening Clinical Reminder for homelessness and risk during a three-month period. RESULTS: Veterans were two or more times as likely to screen positive for homelessness or risk if they had a diagnosis of a cognitive or behavioral health conditions in the study. Findings related to general medical conditions were inconsistent. CONCLUSIONS: The study found disparities in housing instability among VHA outpatients with cognitive and behavioral health conditions, suggesting the need to identify veterans with these conditions experiencing housing instability and the need to develop appropriate interventions to mitigate homelessness or risk.
