Early Supported Discharge for Older Adults Admitted to Hospital after Orthopaedic Surgery: A Systematic Review and Meta-Analysis

Abstract Background Early supported discharge (ESD) aims to link acute and community care, allowing hospital inpatients to return home, continuing to receive the necessary input from healthcare professionals that they would otherwise receive in hospital. Existing literature demonstrates the concept having a reduced length of stay in stroke inpatients and medical older adults. This systematic review aims to explore the totality of evidence for the use of ESD in older adults hospitalised with orthopaedic complaints. Methods A literature search of Cochrane Central Register of Controlled Trials in the Cochrane Library (CENTRAL), EMBASE, CINAHL and MEDLINE in EBSCO was carried out on January 10th, 2024. Randomised controlled trials or quasi-randomised controlled trials were the study designs included. For quality assessment, The Cochrane Risk of Bias Tool 2.0 was used, and GRADE was applied to evaluate the certainty of evidence. Acute hospital length of stay was the primary outcome. Secondary outcomes included the numbers of fallers and function. A pooled meta-analysis was conducted using RevMan software 5.4.1. Results Seven studies with a population of older adults post orthopaedic surgery met inclusion criteria, with five studies included in the meta-analysis. Study quality was predominantly of a high risk of bias. Statistically significant effects favouring ESD interventions were only seen in terms of length of stay (REM, MD = -5.57, 95% CI -7.07 to -4.08, I2 = 0%, P < 0.00001). No statistically significant effects favouring ESD interventions were established in secondary outcomes. Conclusion In the older adult population with orthopaedic complaints, ESD can have a statistically significant impact in reducing hospital length of stay. This review identifies an insufficient existing evidence base to establish the key benefits of ESD for this population group. There is a need for further higher quality research in the area, with standardised interventions and outcome measures used.

Delayed admission of patients with hip fracture from the emergency department is associated with an increased mortality risk and increased length of hospital stay

BackgroundThe aims of this study were to assess whether delayed admission from the ED influenced mortality risk, length of acute hospital stay, risk of developing delirium and return to domicile...

Balanced Fluids Versus Normal Saline for Initial Fluid Resuscitation in Adults With Diabetic Ketoacidosis.

Background: Normal saline (NS) has been the choice fluid for volume resuscitation in diabetic ketoacidosis (DKA) for decades. Large volume resuscitation with NS can lead to hyperchloremic metabolic acidosis and is associated with a higher incidence of major adverse kidney events compared to balanced fluids (BF). Objective: Compare safety and effectiveness of fluid resuscitation with BF vs NS in adult patients with DKA. Methods: Single-center retrospective cohort study evaluated patients who received NS or BF for DKA treatment between July 2020 and August 2021. Primary endpoint was time to DKA resolution. Secondary endpoints included time to anion gap ≤12, HCO3 ≥15 and ≥18mmol/L, acute kidney injury, and hospital and intensive care unit length of stay. Results: 110 patients were included (NS 55% (n = 60), BF 45% (n = 50)). Time to DKA resolution was faster in patients who received BF vs NS (13 (10 - 19) hours vs 17 (11 - 25) hours, P = 0.02). Treatment with NS was associated with a longer time to resolution of DKA when adjusted for initial bicarbonate and AKI at admission. Conclusion: BF was associated with a shorter time to DKA resolution compared to NS.

Empagliflozin to prevent post-operative atrial fibrillation in patients undergoing coronary artery bypass graft surgery: Rationale and design of the EMPOAF trial.

Postoperative atrial fibrillation (POAF) is one of the most common types of acute AF and can complicate the treatment course of approximately one third of patients undergoing cardiac surgery. Sodium-glucose cotransporter-2 (SGLT2) inhibitors are among the newest antidiabetic drugs which can be therapeutic options for preventing POAF by different mechanisms. Empagliflozin to Prevent POAF (EMPOAF) is an interventional, investigator-initiated, double-blind, placebo-controlled, multicenter, randomized controlled trial which will be conducted in two referral teaching cardiology hospitals in Tehran. Four-hundred ninety-two adult patients who are scheduled for elective isolated coronary artery bypass graft (CABG) surgery will be randomly assigned to one of the groups of intervention (empagliflozin 10mg daily) or placebo starting at least 3 days before surgery until discharge. Key exclusion criteria are a history of diabetes mellitus, AF, ketoacidosis, or recurrent urinary tract infections along with severe renal or hepatic impairment, unstable hemodynamics, and patients receiving SGLT2 inhibitors for another indication. The primary outcome will be the incidence of POAF. Key secondary endpoints will be the composite rate of life-threatening arrhythmias, postoperative acute kidney injury, hospitalization length, in-hospital mortality, stroke, and systemic embolization. Key safety endpoints will be the rate of life-threatening and/or genitourinary tract infections, hypoglycemia, and ketoacidosis. EMPOAF will prospectively evaluate whether empagliflozin 10mg daily can reduce the rate of POAF in patients undergoing elective CABG. Enrolment into this study has started by November 2023 and is expected to be ended before the end of 2025.

Drug–Drug Interactions of Hydroxychloroquine and Chloroquine in Older Patients with COVID-19 during the First Pandemic Waves: The GeroCovid Observational Study

Objective: Chloroquine (CQ) and hydroxychloroquine (HCQ) were used as off-label treatments for SARS-CoV-2 infection during the first pandemic waves. The urgency of combatting COVID-19 led to the dissemination of medical recommendations with a scarce awareness of possible drug–drug interactions. This issue primarily concerned people already taking multiple medications, such as older individuals. We estimated the prevalence of drug interactions with CQ or HCQ in COVID-19 inpatients during the first pandemic waves and their possible association with hospitalization-related outcomes. Methods: This study considers 487 patients aged ≥60, hospitalized for COVID-19 from March to December 2020, and treated with CQ or HCQ. Data on acute and chronic therapies and hospitalization length and outcomes were derived from medical records. The presence of drugs potentially interacting with CQ and HCQ was identified based on published literature and drug databases. Results: In our sample (mean age 77.1 years, 47.8% females), 255 (52.4%) patients presented with one drug interaction with CQ or HCQ, and 114 (23.4%) had more than two interactions. The most frequent drugs potentially interacting with CQ or HCQ were lopinavir/ritonavir (50.4%), azithromycin (47.2%), tocilizumab (15.4%), levofloxacin (8.7%), clarithromycin (6.0%), amlodipine (3.3%), and trazodone (2.4%). No substantial differences in the duration and outcomes of the hospitalization emerged as a function of the presence of drug–drug interactions. Conclusions: Many older patients prescribed with CQ or HCQ, which have lately proved ineffective against COVID-19, were exposed to the risk of drug–drug interaction. This underlines that medical recommendations should undergo careful peer review before being widely disseminated, even in emergencies like a pandemic.

Impact of Pharmacist-Driven Penicillin Allergy De-Labeling Pilot Program in Preoperative Cardiothoracic and Spine Surgery Patients at Quaternary Hospital

Documented penicillin allergies are associated with an increased risk of surgical site infections (SSIs), and first-line antibiotics (e.g., cefazolin) are associated with a lower risk of SSIs. The goal of this study was to evaluate the effect of a pharmacist-driven penicillin allergy de-labeling pilot program on the use of preoperative cefazolin in selected surgery patients with documented penicillin allergies. This single-center, quasi-experimental study included adult patients with a charted penicillin allergy who underwent CT or spine surgery in 2021 (control group) or during the 6-month intervention pilot (October 2022–March 2023). In the intervention group, qualifying patients were interviewed via phone to assess allergy history. Qualified patients were de-labeled or referred to an allergist for outpatient skin testing and/or oral challenge. The primary outcome was the rate of cefazolin use preoperatively. Secondary outcomes included 30-day SSIs, Clostridioides difficile infection, acute kidney injury, readmission, and hospital length of stay. Of the intervention group, 57 (79.2%) patients completed the interview. Cefazolin was used preoperatively in 71.0% (152) of the control group versus 88.9% (64) of the intervention group (p < 0.002). There were no clinically significant differences in secondary outcomes. The pharmacist-driven penicillin allergy de-labeling pilot program in CT and spine surgery patients was associated with increased cefazolin use.

Timing of Decompressive Surgery in Patients With Acute Spinal Cord Injury: Systematic Review Update.

Systematic review and meta-analysis. Surgical decompression is a cornerstone in the management of patients with traumatic spinal cord injury (SCI); however, the influence of the timing of surgery on neurological recovery after acute SCI remains controversial. This systematic review aims to summarize current evidence on the effectiveness, safety, and cost-effectiveness of early (≤24hours) or late (>24hours) surgery in patients with acute traumatic SCI for all levels of the spine. Furthermore, this systematic review aims to evaluate the evidence with respect to the impact of ultra-early surgery (earlier than 24hours from injury) on these outcomes. A systematic search of the literature was performed using the MEDLINE database (PubMed), Cochrane database, and EMBASE. Two reviewers independently screened the citations from the search to determine whether an article satisfied predefined inclusion and exclusion criteria. For all key questions, we focused on primary studies with the least potential for bias and those that controlled for baseline neurological status and specified time from injury to surgery. Risk of bias of each article was assessed using standardized tools based on study design. Finally, the overall strength of evidence for the primary outcomes was assessed using the GRADE approach. Data were synthesized both qualitatively and quantitively using meta-analyses. Twenty-one studies met inclusion and exclusion criteria and formed the evidence base for this review update. Seventeen studies compared outcomes between patients treated with early (≤24hours from injury) compared to late (>24hours) surgical decompression. An additional 4 studies evaluated even earlier time frames: <4, <5, <8 or <12hours. Based on moderate evidence, patients were 2times more likely to recover by ≥ 2 grades on the ASIA Impairment Score (AIS) at 6months (RR: 2.76, 95% CI 1.60 to 4.98) and 12months (RR: 1.95, 95% CI 1.26 to 3.18) if they were decompressed within 24hours compared to after 24 hours. Furthermore, moderate evidence suggested that patients receiving early decompression had an additional 4.50 (95% CI 1.70 to 7.29) point improvement on the ASIA motor score. With respect to administrative outcomes, there was low evidence that early decompression may decrease acute hospital length of stay. In terms of safety, there was moderate evidence that suggested the rate of major complications does not differ between patients undergoing early compared to late surgery. Furthermore, there was no difference in rates of mortality, surgical device-related complications, sepsis/systemic infection or neurological deterioration based on timing of surgery. Firm conclusions were not possible with respect to the impact of ultra-early surgery on neurological, functional or safety outcomes given the poor-quality studies, imprecision and the overlap in the time frames examined. This review provides an evidence base to support the update on clinical practice guidelines related to the timing of surgical decompression in acute SCI. Overall, the strength of evidence was moderate that early surgery (≤24hours from injury) compared to late (>24hours) results in clinically meaningful improvements in neurological recovery. Further studies are required to delineate the role of ultra-early surgery in patients with acute SCI.

Boosting inpatient exercise after hip fracture using an alternative workforce: a mixed methods implementation evaluation

BackgroundHip fracture has a devastating impact on individuals and is an increasing burden for health systems and society. Compared to usual care, increased physiotherapy provision has demonstrated efficacy in improving patient and health service outcomes in this population. However, physiotherapy workforce challenges prevent sustained implementation.MethodsOur aim was to evaluate the safety, feasibility, acceptability, effectiveness and implementation cost of thrice daily physiotherapy for patients in the acute care setting after hip fracture at two public hospitals. We added twice-daily exercise implemented by an alternative workforce, to usual care consisting of daily mobility practice by a physiotherapist. Sites identified their preferred alternative workforce, with pre-registration physiotherapy students and allied health assistants chosen. We used a mixed methods approach, using the Consolidated Framework for Implementation Research (CFIR) as a determinant framework to guide implementation planning and data collection. We compared hospital length of stay data to a reference cohort.ResultsWe recruited 25 patients during the study period. Acute care hospital length of stay decreased from 11 days in the reference cohort to 8 days in the BOOST cohort (mean difference − 3.3 days, 95%CI -5.4 to -1.2 days, p = 0.003). Intervention fidelity was 72% indicating feasibility, no safety concerns were attributed to the intervention, and uptake was 96% of all eligible patients. The intervention was acceptable to patients, carers and healthcare providers. This intervention was cost-effective from the acute orthopaedic service perspective.ConclusionHigher daily frequency of physiotherapy can be safely, feasibly and effectively implemented by an alternative workforce for patients in the acute care setting following hip fracture surgery.

Maternal and neonatal outcomes in patients with hepatitis C and intrahepatic cholestasis of pregnancy: The sum of the parts.

Hepatitis C virus and intrahepatic cholestasis of pregnancy (ICP) are well-known independent risk factors for adverse outcomes in pregnancy. In addition, it is well-established that there is an association between Hepatitis C and ICP. This study's objective was to describe the impact of having both Hepatitis C and ICP on maternal and obstetric outcomes compared to patients having either Hepatitis C or ICP. We conducted a retrospective cohort study of the Nationwide Readmissions Database, an all-payor sample of discharges from approximately 60% of US hospitalizations. Deliveries at 24-42+ weeks between 10/2015 and 12/2020 were included. Diagnosis of Hepatitis C and ICP, and outcomes related to severe maternal morbidity were identified using International Classification of Disease-10 codes. Patients were categorized based on Hepatitis C and ICP status. Weighted logistic and negative binomial regression analyses were used to evaluate the association between Hepatitis C and ICP status and outcomes, adjusting for patient and hospital characteristics. The primary outcome was any severe maternal morbidity; secondary outcomes included acute respiratory distress syndrome, acute kidney injury, sepsis, gestational diabetes, cesarean delivery, preterm birth, and hospital length of stay. We modeled interaction terms between ICP and Hepatitis C to assess whether there was a greater or lesser effect from having both conditions on outcomes than we would expect from additive combination of the individual components (i.e., synergy or antagonism). A total of 10,040,850 deliveries between 24-42+ weeks were identified. Of these, 45,368 had Hepatitis C only; 84,582 had ICP only; and 1,967 had both Hepatitis C and ICP. Patients with both Hepatitis C and ICP had 1.5-fold higher odds of developing severe maternal morbidity compared to having neither. There was an also an increased odds of severe maternal morbidity in patients with both Hepatitis C and ICP compared to patients with only Hepatitis C or ICP. Having both was also associated with higher odds of preterm birth and length of stay compared to having only Hepatitis C, only ICP, or neither (preterm birth: aOR 5.09, 95% CI 4.87-5.33 vs. neither; length of stay: 46% mean increase, 95% CI 35-58% vs. neither). Associations were additive-no significant interactions between hepatitis C and cholestasis were found on rates of severe maternal morbidity, acute respiratory distress syndrome, acute kidney injury, sepsis, cesarean section, or preterm birth (all p>0.05), and was minimal for gestational diabetes and length of stay. Hepatitis C and ICP are independent, additive risk factors for adverse maternal and obstetric outcomes. Despite physiologic plausibility, no evidence of a synergistic effect of these two diagnoses on outcomes was noted. These data may be useful in counseling patients regarding their increased risk of adverse outcomes when ICP presents in association with Hepatitis C versus ICP alone.

Epidemiology of major trauma in older adults within Scotland: A national perspective from the Scottish Trauma Audit Group (STAG)

BackgroundMajor trauma in older adults (MTOA) poses distinctive health and social care challenges, further underlined by the unique socioeconomic and geographical environment of Scotland. This study provides epidemiological trends of MTOA, to provide insight into areas where further evaluation and research are required. Materials and MethodsPseudonymised aggregated demographic, injury and outcome data from 2011 to 2020 were obtained from the Scottish Trauma Audit Group (STAG) Database, covering 28 hospitals across Scotland. Only individuals age ≥ 70 with an Injury Severity Score (ISS) > 15 were included. ResultsThere was an average of 216 annual cases of MTOA, with a 259 % rise in incidence from 2011 to 2020. This was predominantly driven by a rise in low velocity trauma (fall <2 m height; 287 % increase).The proportion of all major trauma attributable to those aged ≥70 rose from 18.5 % in 2011 to 34.6 % in 2020. Death censored median (IQR) acute hospital length of stay was 18 days (9–30).Overall, 30-day survival was 65.3 %, with no improvement seen between 2011 and 2020 (p = 0.50). Independent predictors of improved 30-day survival included Ages 70–79 & 80–89 [compared to reference ≥ 90] (OR 3.12; 95 %CI 2.24,4.31; p < 0.001 and OR 1.66; 95 %CI 1.21,2.29; p = 0.002 respectively), and Extremity injury (OR 1.89; 95 %CI 1.48,2.41; p < 0.001). Head injury (OR 0.72; 95 %CI 0.54,0.96; p = 0.027) and increasing ISS score (OR 0.88, 95 %CI 0.86,0.89; p < 0.001) were associated with lower likelihood of 30-day survival. A further model also including the admission ward (from eSTAG data November 2017 onwards) demonstrated an association with reduced 30-day survival with admission to General Surgery (OR 0.42; 95 %CI 0.19,0.93; p = 0.033), Intensive Care (OR 0.25; 95 %CI 0.10,0.60; p = 0.002) and Medical Specialities (OR 0.33; 95 %CI 0.15,0.73; p = 0.007) compared to the reference (Major Trauma).Exponential Smoothing predictions revealed a further potential 184 % rise in incidence of MTOA from 2021 to 2030 (3657 per 100,000 population at risk to 10,392 per 100,000 population at risk). ConclusionMTOA is likely to be a rising health care burden, requiring larger quantities of health and social care resource. Urgent preventative strategies are required to reduce low velocity trauma (standing height falls), as well as the high mortality and morbidity of MTOA.

Completion of the Emergency Department "Big 6" in Patients with an Acute Hip Fracture Is Associated with a Lower Mortality Risk and Shorter Length of Hospital Stay.

The aims of this study were to assess whether completion of the emergency department (ED) Big 6 interventions (provision of pain relief, screening for delirium, early warning score (EWS) system, full blood investigation and electrocardiogram, intravenous fluids therapy, and pressure area care) in those presenting with an acute hip fracture were associated with mortality risk and length of acute hospital stay. A retrospective cohort study was undertaken. All patients aged ≥50 years that were admitted with a hip fracture via the ED at a single centre during a 42-month period were included. A total of 3613 patients (mean age 80.9; 71% female) were included. The mean follow up was 607 (range 240 to 1542) days. A total of 1180 (32.7%) patients had all six components completed. Pain relief (90.8%) was the most frequently completed component and pressure area assessment (57.6%) was the least. Completion of each of the individual Big 6 components, except for pressure areas assessment, were associated with a significantly (p ≤ 0.041) lower mortality risk at the 90-days, one-year and final follow-up. The completion of all components of the Big 6 was associated with a significantly (2.4 hours, p = 0.002) shorter time to theatre. Increasing number of Big 6 components completed were independently associated with a lower mortality risk: when all six were completed, the hazard ratio was 0.64 (95% CI 0.52 to 0.78, p < 0.001). Completion of an increasing number of Big 6 components was independently associated with shorter length of hospital stay and completion of all six was associated with a 2.3 (95% CI 0.9 to 3.8)-day shorter acute stay. The findings provide an evidence base to support the ongoing use of the Big 6 in the ED.

The Use of Methylphenidate During Inpatient Rehabilitation After Pediatric Traumatic Brain Injury: Population Characteristics and Prescribing Patterns.

To understand how methylphenidate (MPH) is used in youth with traumatic brain injury (TBI) during inpatient pediatric rehabilitation. Inpatient pediatric rehabilitation. In total, 234 children with TBI; 62 of whom received MPH and 172 who did not. Patients were on average 11.6 years of age (range, 2 months to 21 years); 88 of 234 were female; the most common mechanism of injury was motor vehicle collision (49%); median (IQR) acute hospital length of stay (LOS) and inpatient rehabilitation LOS were 16 (10-29) and 23 (14-39), respectively; 51 of 234 were in a disorder of consciousness cognitive state at time of inpatient rehabilitation admission. Multicenter, retrospective medical record review. Patient demographic data, time to inpatient pediatric rehabilitation admission (TTA), cognitive state, MPH dosing (mg/kg/day). Patients who received MPH were older (P = .011); TTA was significantly longer in patients who received MPH than those who did not (P =.002). The lowest recorded dose range by weight was 0.05 to 0.89 mg/kg/d, representing an 18-fold difference; the weight-based range for the maximum dose was 0.11 to 0.97 mg/kg/d, a 9-fold difference. Patients in lower cognitive states at admission (P = .001) and at discharge (P = .030) were more likely to receive MPH. Five patients had side effects known to be associated with MPH; no serious adverse events were reported. This multicenter study indicates that there is variable use of MPH during acute inpatient rehabilitation for children with TBI. Children who receive MPH tend to be older with lower cognitive states. Dosing practices are likely consistent with underdosing. Clinical indications for MPH use during inpatient pediatric rehabilitation should be better defined. The use of MPH, as well as its combination with other medications and treatments, during inpatient rehabilitation needs to be further explored.

Evaluation of a tailored pathway for frail and pre frail older people awaiting elective hip or knee arthroplasty

BackgroundOlder patients with clinical osteoarthritis are more likely to have a greater degree of physical frailty. These patients, when subject to a surgical procedure such as arthroplasty, often present with complex perioperative challenges and are more likely to experience adverse postoperative outcomes. AimThe objective of this study was to evaluate the effect of geriatrician-led comprehensive geriatric assessment (CGA) and interventions administered through a POPS (Perioperative care for Older People undergoing Surgery) Service on postoperative length of stay and complications in patients who were pre frail and frail waiting for elective hip or knee arthroplasty. MethodsThis was a retrospective observational cohort study comparing a post intervention cohort with historic controls. Patients ≥ 65 years of age who were waiting for hip or knee arthroplasty with a Clinical Frailty Scale (CFS) ≥4, were evaluated in our POPS @NALHN (Northern Adelaide Local Health Network) service between October 2018 and December 2019. Post-operative outcomes were compared with patients who underwent hip or knee arthroplasty between July 2017 and September 2018, who received usual care. ResultsFollowing multi-domain frailty assessment and interventions through the POPS Service, the average postoperative length of stay was shorter (6.0 days in the control group vs 3.6 days in the intervention group (Incidence Rate Ratio (IRR)=1.66, 95% CI: 1.35, 2.04; P= <0.0001). The control group was 2.5 times more likely to have postoperative complications than the intervention group (Odds Ratio= 2.55, 95% CI 1.17, 5.56, P = 0.018). The control group had a higher incidence of medical complications than the intervention group (IRR =2.01, 95% CI: 1.11, 3.64, P = 0.021). ConclusionProviding a geriatrician-led CGA and interventions to prefrail and frail older adults prior to elective hip or knee arthroplasty was associated with reduced acute hospital length of stay and medical complications. Frailty screening and intervention through CGA in the perioperative setting has the potential to enhance patient care.

Multidisciplinary inpatient rehabilitation for older adults with COVID-19: a systematic review and meta-analysis of clinical and process outcomes

BackgroundOlder adults are at increased risk for disease severity and poorer prognosis following COVID-19 infection. The aim of this systematic review and meta-analysis is to explore the impact of multidisciplinary rehabilitation in the acute or post-acute hospital setting for older adults with COVID-19.MethodsThe Cochrane library, EMBASE, Cinahl and Medline (via EBSCO), PubMed, and Web of Science were systematically searched in June 2022 and a repeat search was completed in March 2023. Screening, data extraction and quality appraisal were conducted independently by two reviewers. Studies reporting outcomes for older adults following multidisciplinary rehabilitation (provided by two or more Health and Social Care Professionals) were included. Both observational and experimental study designs were included. The primary outcome was functional ability. Secondary outcomes included discharge disposition, acute hospital and rehabilitation unit length of stay, mortality, primary and secondary healthcare utilisation, and long-term effects of COVID-19.ResultsTwelve studies met the inclusion criteria, comprising a total of 570 older adults. Where reported, older adults stayed in the acute hospital for a mean of 18 days (95%CI, 13.35- 23.13 days) and in rehabilitation units for 19 days (95%CI, 15.88–21.79 days). There was a significant improvement in functional ability among older adults with COVID-19 who received multidisciplinary rehabilitation (REM, SMD = 1.46, 95% CI 0.94 to 1.98). The proportion of older adults who were discharged directly home following rehabilitation ranged from 62 to 97%. Two studies reported a 2% inpatient mortality rate of older persons during rehabilitative care. No study followed up patients after the point of discharge and no study reported on long term effects of COVID-19.ConclusionsMultidisciplinary rehabilitation may result in improved functional outcomes on discharge from rehabilitation units/centres for older adults with COVID-19. Findings also highlight the need for further research into the long-term effect of rehabilitation for older adults following COVID-19. Future research should comprehensively describe multidisciplinary rehabilitation in terms of disciplines involved and the intervention provided.

The effect of allograft ischemic time on outcomes following bilateral, single, and reoperative lung transplantation

ObjectiveTo determine whether allograft ischemic times affect outcomes following bilateral, single, and redo lung transplantation. MethodsA nationwide cohort of lung transplant recipients from 2005 through 2020 was examined using the Organ Procurement and Transplantation Network registry. The effects of standard (<6 hours) and extended (≥6 hours) ischemic times on outcomes following primary bilateral (n = 19,624), primary single (n = 688), redo bilateral (n = 8461), and redo single (n = 449) lung transplantation were analyzed. A priori subgroup analysis was performed in the primary and redo bilateral-lung transplant cohorts by further stratifying the extended ischemic time group into mild (≥6 and <8 hours), moderate (≥8 and <10 hours), and long (≥10 hours) subgroups. Primary outcomes included 30-day mortality, 1-year mortality, intubation at 72 hours' posttransplant, extracorporeal membrane oxygenation (ECMO) support at 72 hours' posttransplant, and a composite variable of intubation or ECMO at 72 hours' posttransplant. Secondary outcomes included acute rejection, postoperative dialysis, and hospital length of stay. ResultsRecipients of allografts with ischemic times ≥6 hours experienced increased 30-day and 1-year mortality following primary bilateral-lung transplantation, but increased mortality was not observed following primary single, redo bilateral, or redo single-lung transplants. Extended ischemic times correlated with prolonged intubation or increased postoperative ECMO support in the primary bilateral, primary single, and redo bilateral-lung transplant cohorts but did not affect these outcomes following redo single-lung transplantation. ConclusionsSince prolonged allograft ischemia correlates with worse transplant outcomes, the decision to use donor lungs with extended ischemic times must consider the specific benefits and risks associated with individual recipient factors and institutional expertise.

Efficacy and Safety of Prothrombin Complex Concentrates in Liver Transplantation: Evidence from Observational Studies.

The risk/benefit ratio of using prothrombin complex concentrates (PCCs) to correct coagulation defects in patients with end-stage liver disease is still unclear. The primary aim of this review was to assess the clinical effectiveness of PCCs in reducing transfusion requirements in patients undergoing liver transplantation (LT). This systematic review of non-randomized clinical trials was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The protocol was previously registered (PROSPERO:CRD42022357627). The primary outcome was the mean number of transfused units for each blood product, including red blood cells (RBCs), fresh frozen plasma, platelets, and cryoprecipitate. Secondary outcomes included the incidence of arterial thrombosis, acute kidney injury, and haemodialysis, and hospital and intensive care unit length of stay. There were 638 patients from 4 studies considered for meta-analysis. PCC use did not affect blood product transfusions. Sensitivity analysis, including only four-factor PCC, showed a significant reduction of RBC effect size (MD: 2.06; 95%CI: 1.27-2.84) with no true heterogeneity. No significant differences in secondary outcomes were detected. Preliminary evidence indicated a lack of PCC efficacy in reducing blood product transfusions during LT, but further investigation is needed. In particular, future studies should be tailored to establish if LT patients will likely benefit from four-factor PCC therapy.

Abstract 283: Outcomes Among Heart Failure Patients Hospitalized For Aortic Dissection: Insight From The National Inpatient Sample

Background: Aortic dissection is a significant cause of morbidity and mortality among hospitalized patients. Previous studies suggested that heart failure (HF) is a significant complication of aortic dissection which oftentimes lead to poor outcomes due to delays in diagnosis and overall increase disease burden. However, there is paucity of data regarding the outcomes of hospitalized aortic dissection patients with comorbid HF. Methods: We utilized the National Inpatient Sample (NIS) Database of the years 2018-2020 in conducting a retrospective cohort study. All analyses were done through StataBE 17.0. Our outcomes of interests were risk for in-hospital mortality, acute kidney injury (AKI) and hospital length of stay (LOS) among hospitalized aortic dissection patients with comorbid HF. Results: A total of 149,026 hospitalized aortic dissection patients were identified in our study, of which 10.27% (n= 15,305/149,026) had HF. Among those, 6390 met our inclusion criteria. The overall in-hospital mortality among aortic dissection patients was 4.14% (n=6,170/149,026). Among those with concomitant HF, the mortality rate was significantly higher at 6.37%(n=407/6390) (p=0.00). After adjusting for possible patient and hospital level confounders, concomitant HF among aortic dissection patients was deemed to be an independent predictor of overall in-hospital mortality (aOR 2.21; 95% CI, 1.46-3.36; p=0.00) and it was found that systolic (aOR 2.47; 95% CI, 1.42-4.29; p=0.00) and diastolic HF (aOR 2.11; 95% CI, 1.08-4.13; p=0.03) were associated with higher in-hospital mortality compared to those with combined HF (aOR 1.48; 95% CI, 0.44-4.95; p=0.52). Further, concomitant HF increased the risk for the development of in-hospital AKI (aOR 3.16; 95% CI, 2.35-4.24; p=0.00) and longer LOS (aOR 4.16; 95% CI, 2.92-5.40; p=0.00), regardless of HF subtype. Conclusion: Our analysis showed that comorbid HF increased the risk for in-hospital mortality, risk for AKI and longer hospital LOS. On subgroup analysis, systolic and diastolic HF were associated with increased risk for in-hospital mortality and all three HF subtypes increased the risk for AKI and were associated with a longer hospital LOS.

Virtual Care Team Guided Management of Patients With Heart Failure During Hospitalization

BackgroundScalable and safe approaches for heart failure guideline-directed medical therapy (GDMT) optimization are needed. ObjectivesThe authors assessed the safety and effectiveness of a virtual care team guided strategy on GDMT optimization in hospitalized patients with heart failure with reduced ejection fraction (HFrEF). MethodsIn a multicenter implementation trial, we allocated 252 hospital encounters in patients with left ventricular ejection fraction ≤40% to a virtual care team guided strategy (107 encounters among 83 patients) or usual care (145 encounters among 115 patients) across 3 centers in an integrated health system. In the virtual care team group, clinicians received up to 1 daily GDMT optimization suggestion from a physician-pharmacist team. The primary effectiveness outcome was in-hospital change in GDMT optimization score (+2 initiations, +1 dose up-titrations, −1 dose down-titrations, −2 discontinuations summed across classes). In-hospital safety outcomes were adjudicated by an independent clinical events committee. ResultsAmong 252 encounters, the mean age was 69 ± 14 years, 85 (34%) were women, 35 (14%) were Black, and 43 (17%) were Hispanic. The virtual care team strategy significantly improved GDMT optimization scores vs usual care (adjusted difference: +1.2; 95% CI: 0.7-1.8; P < 0.001). New initiations (44% vs 23%; absolute difference: +21%; P = 0.001) and net intensifications (44% vs 24%; absolute difference: +20%; P = 0.002) during hospitalization were higher in the virtual care team group, translating to a number needed to intervene of 5 encounters. Overall, 23 (21%) in the virtual care team group and 40 (28%) in usual care experienced 1 or more adverse events (P = 0.30). Acute kidney injury, bradycardia, hypotension, hyperkalemia, and hospital length of stay were similar between groups. ConclusionsAmong patients hospitalized with HFrEF, a virtual care team guided strategy for GDMT optimization was safe and improved GDMT across multiple hospitals in an integrated health system. Virtual teams represent a centralized and scalable approach to optimize GDMT.

Balanced Nonopioid General Anesthesia With Lidocaine Is Associated With Lower Postoperative Complications Compared With Balanced Opioid General Anesthesia With Sufentanil for Cardiac Surgery With Cardiopulmonary Bypass: A Propensity Matched Cohort Study.

There are no data on the effect of balanced nonopioid general anesthesia with lidocaine in cardiac surgery with cardiopulmonary bypass. The main study objective was to evaluate the association between nonopioid general balanced anesthesia and the postoperative complications in relation to opioid side effects. Patients undergoing cardiac surgery with cardiopulmonary bypass between 2019 and 2021 were identified. After exclusion of patients for heart transplantation, left ventricular assistance device, and off-pump surgery, we classified patients according to an opioid general balanced anesthesia or a nonopioid balanced anesthesia with lidocaine. The primary outcome was a collapsed composite of postoperative complications that comprise respiratory failure and confusion, whereas secondary outcomes were acute renal injury, pneumoniae, death, intensive care unit (ICU), and hospital length of stay. We identified 859 patients exposed to opioid-balanced general anesthesia with lidocaine and 913 patients exposed to nonopioid-balanced general anesthesia. Propensity score matching yielded 772 individuals in each group with balanced baseline covariates. Two hundred thirty-six patients (30.5%) of the nonopioid-balanced general anesthesia versus 186 patients (24.1%) presented postoperative composite complications. The balanced lidocaine nonopioid general anesthesia group was associated with a lower proportion with the postoperative complication composite outcome OR, 0.72 (95% CI, 0.58-0.92; P = .027). The number of patients with acute renal injury, death, and hospital length of stay did not differ between the 2 groups. A balanced nonopioid general anesthesia protocol with lidocaine was associated with lower odds of postoperative complication composite outcome based on respiratory failure and confusion.
