Characteristics of Sickle Cell Clinic Visits and Hospital Admissions in a Large Urban Academic Hospital

Introduction: Although high rates of emergency department (ED) visits by sickle cell disease patient population is a significant health-care system burden, there are limited studies available that explore outpatient/ED visit patterns. The purpose of this study was to evaluate the pattern of medical care utilization including clinic visits and hospital admission in adults with sickle cell disease in a large urban academic center with a dedicated 24 hour/7 day a week sickle cell emergency room. Methods: Patients seen in the Acute Care at Grady Memorial Hospital Comprehensive Sickle Cell Center (GMHSCC) over a three years from January 2015 to December 2017 where analyzed. The Acute Care center at GRMHSCC is a unique 24 hour 7 day a week dedicated emergency room for sickle cell patients. Patient demographics, specialized sickle cell clinic visits and hospital admissions were analyzed descriptively. Independent samples t-test was used for comparison of hospitalization and acute care visits between males/females and phenotype groups. Results: The total of 1,277 patients were included in analysis representing 12,129 acute care visits. 683 (53.5%) females and 593 males (46.5%). Mean age was 32.9 years. Genotypes where similar to known expected distributions, 878 patients had Hb SS (68.8%), 301 had SC (23.6%), 23 had SB0TH (1.8%) and 74 had SB+TH (5.8%). The mean number of acute care visits over 3 years for SS phenotype was 9.71, SC phenotype 9.74, SB+Th phenotype 5.73 and SB0TH phenotype 10.48. Overall admission rate was 16%. There was a significant statistical difference between the mean number of admissions among SS and SC phenotype patients (p=0.009). Rate of hospitalization per clinic visit for SS phenotype was 18.19% , for SC phenotype 10.78% , SB+TH phenotype was 15.58% and SB0TH phenotype 9.55%; Conclusions and future objectives: We have demonstrated that a dedicated Sickle Cell emergency room is able to achieve a significantly lower admission rate than standard Emergency rooms. Preliminary analysis shows that the distribution of acute care visits is distributed across the genotypes at the known distribution. In addition there is no difference in mean number of sickle cell acute visits between patients with SS and SC phenotype. This is interesting as Hgb SC is considered a less severe form of the disease. There was a statistically significant higher admission rate for SS patients compared to SC patients. Future analyses will look at additional parameters associated with acute care visits and admission. Disclosures No relevant conflicts of interest to declare.

Predictors of in-hospital mortality following hypoxic-ischemic brain injury: a population-based study

ABSTRACTObjective: To identify predictors of in-hospital mortality following Hypoxic-Ischemic Brain Injury (HIBI) using the Anderson Behavioral Model.Design and Setting: Population based retrospective cohort study in Ontario, Canada with data collected between 1 April 2002 and 31 March 2017.Patients: Adult patients aged 20 years and older with HIBI-related acute care admission were identified in the health administrative data. Multivariable cox proportional hazard regression models were used to identify predisposing, need and enabling factors that predict in-hospital mortality.Results: Of the 7492 patients admitted to acute care with HIBI, the in-hospital mortality rate was 71%. The predisposing factors associated with mortality were female sex (HR, 1.16; 95% CI, 1.10–1.23) and older age (65–79 vs. 20–34: HR, 1.17; 95% CI, 1.02–1.35). The need factors associated with mortality were the presence of COPD (HR, 1.10; 95% CI, 1.02–1.17), psychiatric illness (HR, 1.13; 95% CI, 1.05–1.20) injury due to cardiac illness (HR, 1.19; 95% CI, 1.12–1.26) and longer emergency department length of stay. Having spending any time in an alternate level of care and the application of tracheotomy procedures were found to reduce mortality.Conclusions: The acute/critical care centers need to consider these findings to adopt prevention strategies targeting reduced in-hospital mortality.

Impact of mental illness on in-patient hospital costs for somatic disorders and associated factors

Abstract Background People suffering from mental disorders are in poorer somatic health that the general population. This is due in part to poor quality of care in primary care settings, which can in turn have a major impact on hospitals and healthcare systems, in particular in terms of costs. Our objective was to assess the economic burden of acute care admissions for somatic diseases in patients with a mental illness compared to other patients and analyse the factors associated with it. Methods An exhaustive study using French hospital discharge databases was carried out between 2009 and 2013. Total acute hospital costs were calculated from the all payer perspective (statutory health insurance, private health insurances and patient out-of pocket payments). A multivariate regression modelled the association between mental illness and hospital costs while adjusting for other explanatory variables, with and without interaction terms. Results 37,458,810 admissions were included in the analysis. 1,163,972 patients (6.54%) were identified as being mentally ill. Mean total hospital costs at five years per patient were €8,114. Costs per mentally ill patient were on average 34% higher than for a non-mentally patient (€10,637 vs. €7,949). A longitudinal analysis of costs showed a widening of the gap between the two groups as time went by, from 1.60% in 2009 to 10.51% in 2013. In the multivariate model, mental disorders were significantly associated with increased costs, and interaction terms found an increased impact of mental illness on costs in deprived patients. Conclusions Improving quality of primary care and health promotion in people with a mental illness both for their own sake and to decrease the economic burden on the healthcare system, is of vital importance. Key messages There is a significant increase in hospital costs for somatic care in patients with a mental illness compared to other patients, in particular in patients who are also deprived. It is necessary to improve primary care and health promotion in mentally ill patients, for their sake and for the sake of healthcare systems.

2892. The Relationship Between Inpatient and Post-discharge Antimicrobial Use at the Hospital-level Across an Integrated Healthcare Network

BackgroundHospital-based antimicrobial stewardship interventions and metrics have typically focused only on inpatient antimicrobial exposure. However, single-center studies have found a large portion of antimicrobial exposure occurs immediately after hospital discharge. We sought to describe antimicrobial-prescribing upon hospital discharge across the Veterans Health Administration (VHA) and to compare inpatient and post-discharge antimicrobial use at the hospital-level.MethodsThis retrospective study used national VHA administrative data to identify all acute-care admissions from January 1, 2014 to December 31, 2016. Post-discharge antimicrobials were defined as oral outpatient antimicrobials prescribed at the time of hospital discharge. We measured inpatient-days of therapy (DOT) and post-discharge DOTs. At the hospital-level, inpatient DOTs per 100 admissions were compared with post-discharge DOTs per 100 admissions using Spearman’s rank-order correlation.ResultsAmong 1.7 million acute-care admissions across 122 VHA hospitals, 46.1% were administered inpatient antimicrobials and 19.9% were prescribed an oral antimicrobial at discharge. Fluoroquinolones were the most common antimicrobial prescribed at discharge among 335,396 antimicrobial prescriptions (38.3%). At the hospital-level, median inpatient antimicrobial use was 331.3 DOTs per 100 admissions (interquartile range (IQR) 284.9–367.9) and median post-discharge use was 209.5 DOTs per 100 admissions (IQR 181.5–239.6). Thirty-nine percent of the total duration of antimicrobial exposure occurred after hospital discharge. The metrics of inpatient DOTs per 100 admissions and post-discharge DOTs per 100 admissions were weakly correlated at the hospital-level (rho = 0.44, P < 0.0001).ConclusionAntimicrobial-prescribing at hospital discharge was common and contributed substantially to the total antimicrobial exposure associated with an acute-care hospital stay. A hospital’s inpatient antimicrobial use was only weakly correlated with its post-discharge antimicrobial use. Antimicrobial stewardship interventions should specifically target antimicrobial-prescribing at discharge.Disclosures All Authors: No reported Disclosures.

Post-discharge oral antimicrobial use among hospitalized patients across an integrated national healthcare network

ObjectivesAntimicrobial stewardship programmes have focused on reducing inappropriate inpatient antimicrobial prescribing, but several small studies have found a large portion of antimicrobial exposure occurs immediately after hospital discharge. In this study, we describe the prescribing of oral antimicrobials at hospital discharge across an integrated national healthcare system. At the hospital level, we also compare total inpatient antimicrobial use and post-discharge oral antimicrobial use. MethodsThis retrospective cross-sectional study used national administrative data to identify all acute-care admissions during 2014–2016 within the Veterans Health Administration (VHA). We evaluated inpatient days of therapy (DOT) and post-discharge DOT, defined as oral outpatient antimicrobials dispensed at the time of hospital discharge. At the hospital level, inpatient DOT/100 admissions were compared with post-discharge DOT/100 admissions using Spearman's rank-order correlation. ResultsThere were 1 681 701 acute-care admissions across 122 hospitals, and 335 369 (19.9%) were prescribed an oral antimicrobial at discharge. Fluoroquinolones (38.3%) were the most common post-discharge antimicrobial. At the hospital level, median inpatient antimicrobial use was 331.3 (interquartile range (IQR) 284.9–367.9) DOT/100 admissions and median post-discharge use was 209.5 (IQR 181.5–239.6) DOT/100 admissions. Thirty-nine per cent of the total duration of antimicrobial exposure occurred after discharge. At the hospital-level, the metrics of inpatient DOT/100 admissions and post-discharge DOT/100 admissions were weakly positively correlated with rho=0.44 (p < 0.001). ConclusionsA large proportion of antimicrobial exposure among hospitalized patients occurred immediately following discharge. Antimicrobial-prescribing at hospital discharge provides an opportunity for antimicrobial stewardship. Hospital-level stewardship metrics need to include both inpatient and post-discharge antimicrobial-prescribing to provide a comprehensive assessment of hospital-associated antimicrobial use.

Inpatient Palliative Care Consult: A Marker for High Risk of Readmission or Death in Discharged Oncology Inpatients.

Emergency department visits or readmission to hospital are common particularly among those with advanced illness. Little prospective data exist on early outcomes specifically for patients seen by a palliative care consult service during their acute care admission, who are subsequently discharged home. This study followed 62 oncology patients who had had a palliative care consult during their admission to acute care with weekly phone calls postdischarge for 4 weeks. Events recorded included death, readmission, emergency department visits, and admission to a palliative care unit. By the end of the study, 32 (52%) of 62 had had at least 1 event, (readmission, emergency department visit, or death), with the majority of these occurring in the first 2 weeks postdischarge. The overall 4-week death rate was 14 (22.6%) of 62. These data suggest that the need for a palliative care consult identifies inpatients at very high risk for early deterioration and underlines the critical importance of advance care planning/goals-of-care discussions by the oncology and palliative care teams to ensure patients and families understand their disease process and have the opportunity to direct their care decisions.

Association Between Care Management and Outcomes Among Patients With Complex Needs in Medicare Accountable Care Organizations

People with complex needs account for a disproportionate amount of Medicare spending, partially because of fragmented care delivered across multiple practitioners and settings. Accountable care organization (ACO) contracts give practitioners incentives to improve care coordination to the extent that coordination initiatives reduce total spending or improve quality. To assess the association between ACO-reported care management and coordination activities and quality, utilization, spending, and health care system interactions in older adults with complex needs. In this cross-sectional study, survey information on care management and coordination processes from 244 Medicare Shared Savings Program ACOs in the 2017-2018 National Survey of ACOs (of 351 Medicare ACO respondents; response rate, 69%) conducted from July 20, 2017, to February 15, 2018, was linked to 2016 Medicare administrative claims data. Medicare beneficiaries 66 years or older who were defined as having complex needs because of frailty or 2 or more chronic conditions associated with high costs and clinical need were included. Beneficiary attribution to ACO reporting comprehensive (top tertile) care management and coordination activities. All-cause prevention quality indicator admissions, 30-day all-cause readmissions, acute care and critical access hospital admissions, evaluation and management visits in ambulatory settings, inpatient days, emergency department visits, total spending, post-acute care spending, health care contact days, and continuity of care (from Medicare claims). Among 1 402 582 Medicare beneficiaries with complex conditions, the mean (SD) age was 78 (8.0) years and 55.1% were female. Compared with beneficiaries assigned to ACOs in the bottom tertile of care management and coordination activities, those assigned to ACOs in the top tertile had identical median prevention quality indicator admissions and 30-day all-cause readmissions (0 per beneficiary across all tertiles), hospitalization and emergency department visits (1.0 per beneficiary in bottom and top tertiles), evaluation and management visits in ambulatory settings (14.0 per beneficiary [interquartile range (IQR), 8.0-21.0] in both tertiles), longer median inpatient days (11.0 [IQR, 4.0-33.0] vs 10.0 [IQR, 4.0-32.0]), higher median annual spending ($14 350 [IQR, $4876-$36 119] vs $14 229 [IQR, $4805-$36 268]), lower median health care contact days (28.0 [IQR, 17.0-44.0] vs 29.0 [IQR, 18.0-45.0]), and lower continuity-of-care index (0.12 [IQR, 0.08-0.20] vs 0.13 [IQR, 0.08-0.21]). Accounting for within-patient correlation, quality, utilization, and spending outcomes among patients with complex needs attributed to ACOs were not statistically different comparing the top vs bottom tertile of care management and coordination activities. The ACO self-reports of care management and coordination capacity were not associated with differences in spending or measured outcomes for patients with complex needs. Future efforts to care for patients with complex needs should assess whether strategies found to be effective in other settings are being used, and if so, why they fail to meet expectations.

Association of Weekend Admission and Clinical Outcomes in Hospitalised Adult Patients with Sepsis

Background: Sepsis is associated with detrimental clinical outcomes. It requires early diagnosis and urgent therapeutic intervention. Because staffing during after-hours is limited, we explored whether after-hour admissions are associated with worse clinical outcomes in patients with sepsis. Methods: In this cohort study, we analysed nationwide acute care admissions for a main diagnosis of sepsis in Switzerland between 2006 and 2016 using prospective administrative data. The primary outcome was in-hospital mortality using multivariate logistic regression models. Secondary outcomes were intensive care unit (ICU) admission, intubation, and 30-day readmission. Findings: We included 86`597 hospitalisations for sepsis, 60·1% admitted during routine-hours, 16·8% on weekends and 23·1% at night. Compared to routine-hour admissions, we found a higher risk for in-hospital mortality in patients admitted on weekends (20·0% vs. 19·2%, adjusted odds ratio [OR] 1·05, 95% confidence interval [95% CI] 1·01-1·10, p=0·029). Also, the risk for ICU admission (30·5% vs. 28·0%, OR 1·14, 95% CI 1·10-1·19, p<0·0001) and intubation (14·7% vs. 12·9%, OR 1·18, 95% CI 1·12-1·25 p<0·0001) was higher for weekends compared to routine-hour admissions. There were no differences in 30-day readmission rates. Night shift admission, compared to routine-hour admission, also had a higher risk for ICU admission and intubation, whereas in-hospital mortality was not increased. Interpretation: Among hospitalisations with a main diagnosis of sepsis, weekend admissions were associated with higher risk for in-hospital mortality, ICU admission, and intubation. Whether these findings can be explained by staffing-level differences needs to be addressed.

Cost of hospital care for the older adults according to their level of frailty. A cohort study in the Lazio region, Italy.

BackgroundThe increasing burden of chronic diseases associated with the ageing of the European population constitutes one of the main challenges for the welfare systems in developed western countries, especially through its impact on the use of hospital services and the cost of care. This study aims at evaluating the cost of hospital care for older adults living in the Lazio Region, Italy, according to their level of frailty.MethodsSince 2014 a longitudinal randomized cohort study has been carried out on a sample consisting of 1280 older adults aged over 64 years resident in the Lazio region (Italy), with their being evaluated for multidimensional frailty. Accesses to Hospital Services (acute care and Day Hospital care admissions and Emergency Room accesses) during the first year after enrolment, as well as the related costs have been recorded through a regional database. Costs have been stratified on the basis of the state of frailty.ResultsThe analysis of hospital services and costs highlights the role played by pre-frail individuals who generated 49.3% of the hospital care cumulative costs. Hospital Admission (HA) costs arising from robust and pre-frail subjects are 70% of the total HA costs. Pre-frail individuals also showed the highest average HA cost per person/year (7062.89 Euros). The main determinant of the highest HA costs was given by the number of HAs during the follow-up (multivariate linear regression, ß coefficient = 0.319; p<0.001), which was higher among pre-frail individuals than in any other group of patients.ConclusionsPre-frail individuals generated the highest cost for hospital care in a sample of representative subjects living in an Italian Region with a low rate of community care services, as is the case in the Lazio region. Assessment of the multidimensional frailty of older adults permits a better definition of the important target of the pre-frail population as the main category within which interventions to prevent or mitigate frailty should be carried out.

Outcomes after single-look trauma laparotomy: A large population-based study.

Outcomes following damage control laparotomy for trauma have been studied in detail. However, outcomes following a single operation, or "single-look trauma laparotomy" (SLTL), have not. We evaluated the association between SLTL and both short-term and long-term outcomes in a large population-based data set. The California Office of Statewide Health Planning and Development patient discharge database was evaluated for calendar years 2007 through 2014. Injured patients with SLTL during their index admission were identified using International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. Diagnosis and procedure codes were used to identify specific abdominal organ injuries, surgical interventions, and perioperative complications. Subsequent acute care admissions were examined for postoperative complications and related surgical interventions. Clinical characteristics, injuries, surgical interventions, and outcomes were analyzed by mechanism of injury. There were 2113 patients with SLTL during their index admission; 712 (33.7%) had at least one readmission to an acute care facility. Median time to first readmission was 110 days. Penetrating mechanism was more common than blunt (60.6% vs. 39.4%). Compared to patients with penetrating injury, blunt-injured patients had a significantly higher median Injury Severity Score (9 vs. 18, p < 0.0001) and a significantly higher mortality rate during the index admission (4.1% vs. 27.0%, p < 0.0001). More than 30% of SLTL patients requiring readmission had a surgery-related complication. The most common primary reasons for readmission were bowel obstruction (17.7%), incisional hernia (11.8%), and infection (9.1%). There was no significant association between mechanism of injury and development of surgery-related complications requiring readmission. Patients with SLTL had postinjury morbidity and mortality, and more than 30% required readmission. Complication rates for SLTL were comparable to those reported for emergency general surgery procedures. Patients should be educated on signs and symptoms of the most common complications before discharge following SLTL. Further investigation should focus on the factors associated with the development of these complications. Prognostic and epidemiologic study, level III.

Cost-effectiveness of a high-intensity rapid access outpatient stroke rehabilitation program.

A common strategy to improve cost-effectiveness in healthcare is to offer outpatient care instead of in-hospital care. Toronto Rehabilitation Institute developed an outpatient high-intensity fast-track (FT) stroke rehabilitation program aimed at discharging inpatient stroke rehabilitation patients earlier or bypassing inpatient rehabilitation altogether. This cost-effectiveness analysis compares FT rehabilitation within 1 week of discharge with no FT in a single healthcare payer system. Patient costs and outcomes over a 12-week time horizon were included. Using individual-level FT data from April 2015 to March 2016, incremental cost-effectiveness ratios (ICERs) (with 95% confidence interval) were estimated using regression. Subgroup analysis was completed for patients entering FT directly from inpatient rehabilitation and acute stroke care. Uncertainty was assessed using a cost-effectiveness acceptability curve with a range of willingness-to-pay values ($0-1000 per inpatient day saved). ICER (95% confidence interval) estimate for patients entering FT from inpatient rehabilitation was $404 ($270-620) per inpatient day saved. ICER estimate for direct from acute care admissions was $37 ($20-55) per day saved. At willingness-to-pay of $698 (cost of one alternate level of care day in acute care awaiting rehabilitation), the probability of FT being cost-effective was 99.2 and 100% for patients from inpatient rehabilitation and acute stroke care, respectively. From a single healthcare payer perspective, FT is a cost-effective method of providing appropriate rehabilitation intensity for stroke patients early on, and likely to provide savings to the healthcare system upstream through fewer days awaiting rehabilitation admission.

Trends in Hospital Utilization for Acute Illness in a Large Population-Based Cohort of Children and Adolescents with Sickle Cell Disease (SCD): 2010–2017

Disease severity and healthcare utilization varies widely among persons with sickle cell disease (SCD). Hydroxyurea (HU) has been demonstrated to reduce rates of pain and acute chest syndrome, the leading causes of inpatient utilization in patients with Hb SS and S β°-thalassemia in clinical trials. We recently reported that HU was clinically effective in reducing rates of pain and acute chest syndrome in patients who initiate treatment. Use of hydroxyurea in SS/S β°-thalassemia has increased markedly since 2010. Thus we sought to detemine trends of hospital utilization for acute illness during an 8 yr in which HU utilization increased markedly (2010-2017). Data from years 2010-201 were obtained from the SCD database and patient records at Children's Healthcare of Atlanta (CHOA). Utilization data were restricted to acute care admissions. Admissions for elective procedures, non-SCD related discharge diagnoses, rare SCD genotypes, and patients who had undergone bone marrow transplant were excluded. Patients were compared based on number of hospitalizations, age, sex, SCD genotype (SS/S β°-thalassemia vs Hb SC/S β+thalassemia), and discharge diagnosis. A total of 3,116 patients had at least one encounter between 2010 and 2017; 2,947 patients met inclusion criteria. From 2010-2017 the total number of active patients per year increased from 1,546 patients to 1,789 patients (+16%), while the total number acute care admissions increased from 1,295 admissions to 1,609 admissions (+24%). There were no significant differences in the proportion of patients with genotypes SS/S β° thalassemia genotypes (67.0% vs 63.9%, p=0.06). Overall patients with SS/S β° thalassemia had higher admission rates compared to SC/S β+ thalassemia patients (0.94 vs 0.57 admissions per patient per year). During the study period. overall admission rates in SCD (acute illness hospitalizations/patient/yr) increased from a low of 0.74 in 2011 to a high of 0.90 in 2017. The proportion of admissions attributed to SS/S β°-thalassemia patients decreased (79.2% in 2010 vs 72.3% in 2017, p<0.0001). However, admission rate in SC/S β+ thalassemia increased (0.53 to 0.69 admissions per patient per year). Overall, over 60% of patients were not admitted in any given year, and the proportion of patients with 0-1 admissions in a given year remained unchanged. However, the proportion of super high hospital utilizers (SHHU), patients with 8 or more admissions in a given year, increased by 185%. In 2001 this group made up 0.6% of all patients and accounted for 7.3% of admissions; in 2017 SHHU had increased 1.8% of patients and 24.3% of admissions. There was no difference in genotype or sex between SHHU and non-SHHU patients. SHHU were older (>90% of patients over age 8 years), and had greater percentages of admissions for pain and acute chest syndrome then non-SHHU. In conclusion, during a period in which HU utilization in SS/S β°-thalassemia increased significantly, hospital utilization for acute illness in SS/S β° thalassemia decreased as expected. However, during the same period there was an unexpected increase in overall hospital utilization for acute illness in SCD. This increase in hospital utilization was the result of 1) a marked increase in SHHU and 2) an overall increased utilization in SC/S β+ thalassemia. DisclosuresDampier:Pfizer: Research Funding.

Role of Automated Red Cell Exchange in Acute and Chronic Complications of Sickle Cell Disease

Background. Automated red cell exchange transfusion (ARCET) is commonly used in patients with sickle cell disease, but objective data on its impact on acute and chronic complications are limited.Methods. Fifty-two sickle cell disease patients at the University of Illinois at Chicago underwent exchange transfusion from January 2011 to January 2016. Six patients were excluded due to incomplete data leaving 46 patients available for analysis. We collected data from the year before, year after and the year of ARCET to study the impact of red cell exchange on clinical, biological and hematological parameters.Results. There were 435 procedures with average of 9.45 per patient (range 4-14). The mean age of our cohort was 58.2 years. There were 22 (47.8%) males and 24 (52.2%) females. Genotypes include 42 (91.3%) HbSS, 1 (2.2%) HbSC, 1 (2.2%) HbSBeta+thalassemia and 2 (4.3%) HbSBeta0thalassemia. The most common indication for ARCET in our cohort was prior stroke in 32 patients (69.6%) and prevention of stroke in 7 patients (15.2%), followed by frequent vaso-occlusive crisis (VOC) 8 patients (17.4%), multiple acute chest syndrome 6 patients (13%), pulmonary hypertension 6 patients (13%) and chronic kidney disease 5 patients (8.9%). Iron overload, sickle hepatopathy, cardiomyopathy and seizure were some of the other indications. Twenty-five patients (54.3%) had more than one indication to undergo the ARCET. Thirty-one patients (67.4%) are still continuing the treatment. Thirty patients (65.2%) were on hydroxyurea (HU) prior to ARCET and 8 patients (17.4%) were still on HU while on ARCET. The mean frequency of ARCET was every 6 weeks. The mean pre and post ARCET values for hemoglobin(Hb), hematocrit (Hct), Hemoglobin S %(HbS), white cell count (wbc) and platelets(plt) are shown in Table 1. Paired t-test and Wilcoxon signed-rank test were used to analyze the clinical and hematological parameters. Analysis shows increase in mean Hb and Hct post ARCET and decrease in mean wbc, plt and HbS % post ARCET and the difference is statistically significant. (Table 3). Post ARCET body mass index (BMI) and weight are increased and the difference is statistically significant with p value 0.002 for BMI and 0.003 for weight. (Table 3). Ten (21.7%) patients showed decrease in the ferritin level post exchange. Thirty patients (65%) had VORTEX port whereas 29 patients (63%) had central venous access for procedures prior to Vortex placement (17/29, 59%). Nine patients (20%) had peripheral access mostly power port (for access) with one peripheral vein for return (6/9 67%). There were 10 access related complications and there were 3 port replacements due to septum damage and infection. There were 10 procedure related complications and 10 transfusion reactions as described in Table 2. ED admissions were decreased in 13(28.3%) patients from mean 7.69 to 2.92 admissions. The annual inpatient admissions showed a decrease in 18(39.2%) patients from mean 4.6 days pre ARCET to 1.6 admissions post ARCET. The acute care admissions showed an increase due to program expansion of our acute care center during this study period.Discussion. Our study shows that red cell exchange is an effective treatment modality for patients with sickle cell disease. It contributes to improvement in weight, increase in Hb and Hct and decrease in wbc, plt, HbS% and iron overload. It also decreases inpatient and ED admissions. The procedure is safe and tolerable with minimal complications. Long term studies are needed study the efficacy of this treatment modality and its contribution to improvement of quality of life and life expectancy in sickle cell disease patients.

1216. Cost-Effectiveness of Penicillin Skin Allergy Testing in Methicillin-Sensitive Staphylococcus aureus (MSSA) Bacteremia

Backgroundβ-Lactams remain the gold standard for treatment of MSSA bacteremia due to superior outcomes compared with vancomycin. Approximately nine in 10 patients receiving penicillin skin testing (PST) will be de-labeled of a penicillin allergy and able to receive a β-lactam antibiotic. The study aims to evaluate the cost-effectiveness of penicillin allergy confirmation during acute care admission for methicillin-sensitive staphylococcus aureus (MSSA) bacteremia through a PST service.MethodsA decision tree analysis was used to compare a PST intervention in patients with a registeredpenicillin allergy during an inpatient admission for MSSA bacteremia vs. usual care (No PST). The model was created from the health sector perspective with a 1-year time horizon. Patients with a penicillin allergy label were expected to receive vancomycin while patients with no penicillin allergy were expected to receive cefazolin. Potential inpatient, outpatient, and adverse reaction costs were considered in all arms of the model. The effects were measured in quality adjusted life years (QALY) and were calculated for patients who were cured, hospitalized, experienced severe adverse events, or died from MSSA infection.ResultsPatients who received PST services had a mean yearly cost of $12,802, mean quality adjusted life years (QALY) of 0.70, and mean cost/QALY of $18,311. The comparator group not receiving PST services had a mean yearly cost of $12,264, mean quality adjusted life years (QALY) of 0.64, and mean cost/QALY of $19,192. The model produced a final base case ICERof $8,966/QALY for receiving a PST during a hospital admission for the treatment of methicillin-sensitive staphylococcus aureus (MSSA) bacteremia.ConclusionPenicillin allergy confirmation through PST services was cost-effective for patients with a reported penicillin allergy admitted for MSSA bacteremia. Additional research to determine potential benefits of PST services beyond one year could further improve the cost-effectiveness of this intervention.Disclosures S.

Practice transformation: Early impact of OCM on hospital admissions.

30 Background: The purpose of the Oncology Care Model is to improve quality and reduce cost through practice transformation. A foundational tenant is to reduce avoidable ER visits and hospitalizations. In anticipation of being an OCM participant, we instituted a multidimensional campaign designed to meet these objectives. Methods: Prior Actions: Established phone triage unit. After-hours and weekend call. Instituted weekend urgent care. Year One: Improved education provided by nurse navigators and APPs prior to start of treatment (OCM Treatment Planning visit). Implemented triage pathways: 38 symptom and 27 follow-up pathways (modified COME HOME, Barbara McAneny, M.D.). Proactive symptoms follow-up calls to help circumvent emergent admissions. Increased APP staffing to provide blocked time slots for same day patient visits w/o schedule disruptions. Initiated “Call Us Early – Call Us First” campaign. Incorporated verbal and/or written instructions at all patient touch points, emphasizing patient’s responsibility to call before going to the emergency room. Results: Based on data from the Chronic Condition Warehouse, as provided by CMS, we were successful at reducing the acute care admissions rate by 16 percent. Conclusions: By implementing a cost efficient, reproducible, and scalable campaign targeting ER avoidance and hospitalizations, we were able to decrease hospital admissions. Reported Medicare savings amounted to nearly $798,000 in inpatient cost per quarter over 1,600 patients.[Table: see text]

Readmission following hypoxic ischemic brain injury: a population-based cohort study.

Readmission to acute care is common and is associated with indicators of suboptimal care and health system inefficiencies. The objective of this study was to identify independent determinants of readmission following survival of hypoxic ischemic brain injury. We conducted a population-based retrospective cohort study using Ontario's administrative health data. Survivors of hypoxic ischemic brain injury aged 20 years or more discharged from acute care between fiscal years 2002/03 and 2010/11 were included. Multivariable negative binomial regression was used to identify independent determinants of both number of readmissions and cumulative duration of hospital stay(s) within 1 year after the index discharge. Of the 593 patients with hypoxic ischemic brain injury, 233 (39.3%) were readmitted within 1 year of the index acute care discharge. The number of readmissions was associated with age (35-49 yr v. 65-79 yr: rate ratio [RR] 0.57, 95% confidence interval [CI] 0.38-0.85; ≥ 80 yr v. 65-79 yr: RR 0.58, 95% CI 0.34-0.97) and higher comorbidity score (Johns Hopkins Aggregated Diagnosis Groups score > 30 v. < 10: RR 1.60, 95% CI 1.11-2.31). Cumulative readmission stay was associated with increased index acute care length of stay (31-90 d v. ≥ 90 d: RR 4.17, 95% CI 1.38-12.64), prior use of health care services (minimal v. very high: RR 0.15, 95% CI 0.05-0.49) and discharge disposition (home v. continuing/long-term care: RR 0.44, 95% CI 0.21-0.91). The findings indicate a high readmission rate in the first year after the index acute care admission for survivors of hypoxic ischemic brain injury, reflecting care gaps and system inefficiencies. This suggests that bolstered discharge and home care planning and support are needed to address the specific needs of those with hypoxic ischemic brain injury.

Practice Transformation: Early Impact of the Oncology Care Model on Hospital Admissions

The purpose of the Oncology Care Model (OCM) is to improve quality and reduce cost through practice transformation. A foundational tenant is to reduce avoidable emergency room (ER) visits and hospitalizations. In anticipation of being an OCM participant, we instituted a multidimensional campaign designed to meet these objectives. Prior actions included establishment of phone triage unit, after-hours and weekend calls, and institution of weekend urgent care. On the basis of data from the Chronic Condition Warehouse, as provided by the Centers for Medicare and Medicaid Services, we were successful at reducing the acute care admissions rate by 16%. During the baseline period extending from Jan 2016-Mar 2016, the hospital admission rate was 27 per patient, per quarter, at an average cost per admission event of $11,122, translating to an inpatient cost per patient, per quarter, of $3,003. In the year one reporting period of July 2016-July 2017, the hospital admission rate declined to 22.6 per patient, per quarter, at an average cost per admission event of $11,106, translating to an inpatient cost per patient, per quarter, of $2,505. OCM patient survey scores improved. In addition, at Oncology Hematology Care, we achieved improved results compared with the risk-adjusted national averages for the following measures: readmissions (4.9 v 5.6 per 100 patients, respectively), ER use (17 v 18.6 per 100 patients, respectively), and observation stays (2.7 v 3.6 per 100 patients, respectively). By implementing a cost-efficient, reproducible, and scalable campaign targeting ER avoidance and hospitalizations, we were able to decrease hospital admissions. Reported Medicare savings amounted to nearly $798,000 in inpatient cost per quarter over 1,600 patients.

Characteristics and outcomes of emergency interhospital transfers from subacute to acute care for clinical deterioration

To describe characteristics and outcomes of emergency interhospital transfers from subacute to acute hospital care and develop an internally validated predictive model to identify features associated with high risk of emergency interhospital transfer. Prospective case-time-control study. Acute and subacute healthcare facilities from five health services in Victoria, Australia. Cases were patients with an emergency interhospital transfer from subacute to acute hospital care. For every case, two inpatients from the same subacute care ward on the same day of emergency transfer were randomly selected as controls. Admission episode was the unit of measurement and data were collected prospectively. Patient and admission characteristics, transfer characteristics and outcomes (cases), serious adverse events and mortality. Data were collected for 603 transfers in 557 patients and 1160 control patients. Cases were significantly more likely to be male, born in a non-English speaking country, have lower functional independence, more frequent vital sign assessments and experience a serious adverse event during first acute care or subacute care admissions. When adjusted for health service, cases had significantly higher inpatient mortality, were more likely to have unplanned intensive care unit admissions and rapid response team calls during their entire hospital admission. Patients who require an emergency interhospital transfer from subacute to acute hospital care have hospital admission rates and in-hospital mortality. Clinical instability during the first acute care admission (serious adverse events or increased surveillance) may prompt reassessment of patient suitability for movement to a separate subacute care hospital.

Transmission of Clostridium difficile from asymptomatically colonized or infected long-term care facility residents.

To test the hypothesis that long-term care facility (LTCF) residents with Clostridium difficile infection (CDI) or asymptomatic carriage of toxigenic strains are an important source of transmission in the LTCF and in the hospital during acute-care admissions. A 6-month cohort study with identification of transmission events was conducted based on tracking of patient movement combined with restriction endonuclease analysis (REA) and whole-genome sequencing (WGS). Veterans Affairs hospital and affiliated LTCF.ParticipantsThe study included 29 LTCF residents identified as asymptomatic carriers of toxigenic C. difficile based on every other week perirectal screening and 37 healthcare facility-associated CDI cases (ie, diagnosis >3 days after admission or within 4 weeks of discharge to the community), including 26 hospital-associated and 11 LTCF-associated cases. Of the 37 CDI cases, 7 (18·9%) were linked to LTCF residents with LTCF-associated CDI or asymptomatic carriage, including 3 of 26 hospital-associated CDI cases (11·5%) and 4 of 11 LTCF-associated cases (36·4%). Of the 7 transmissions linked to LTCF residents, 5 (71·4%) were linked to asymptomatic carriers versus 2 (28·6%) to CDI cases, and all involved transmission of epidemic BI/NAP1/027 strains. No incident hospital-associated CDI cases were linked to other hospital-associated CDI cases. Our findings suggest that LTCF residents with asymptomatic carriage of C. difficile or CDI contribute to transmission both in the LTCF and in the affiliated hospital during acute-care admissions. Greater emphasis on infection control measures and antimicrobial stewardship in LTCFs is needed, and these efforts should focus on LTCF residents during hospital admissions.
