Abstract Background VVancomycin and dalbavancin, both in the glycopeptide class of antibiotics, are used in the treatment of Gram-positive infections, including methicillin-resistant Staphylococcus aureus. Antibiotics in this class contain a heptapeptide core that has potential for cross-sensitivity. Due to this risk, dalbavancin carries a warning in the package insert for use in patients with a glycopeptide allergy. Dalbavancin, a semi-synthetic derivative of vancomycin, has lipophilic side chains which reduce the risk of cross-sensitivity to vancomycin. This case series evaluated patients with a listed vancomycin allergy in their electronic health record who received dalbavancin as an outpatient infusion. Methods This study was a non-randomized, retrospective chart review of adult patients who had a documented vancomycin allergy and received dalbavancin between February 2016 and February 2021 for any indication in the outpatient setting. The primary objective was to evaluate dalbavancin tolerability in patients allergic to vancomycin. Patient characteristics and the specifics of dalbavancin infusion – dose, volume, infusion rate, intravenous line access, and receipt of premedication before infusion – were collected on each patient. Results 559 unique patients received dalbavancin over the time frame. Of these, ten had a documented, subjective vancomycin allergy. Patient-reported allergic reactions were rash (4), hives (3), anaphylaxis (2), red man syndrome (2), renal failure (2), and general malaise (1). Six patients had at least 1 additional subjective drug allergy. The various infections treated included cellulitis/abscess (8), osteomyelitis (1), and bacteremia (2). Most patients received 1500mg (2 received 1125mg) of dalbavancin in 300-500mL of dextrose 5% in water infused at either 600 or 1000mL/hr via a peripheral (6) or central (4) intravenous line. All patients tolerated the infusion with no adverse events reported and no receipt of premedication before administration. Conclusion Dalbavancin may be a reasonable treatment option in vancomycin allergic patients, despite possible cross-sensitivity. Further investigation into cross-sensitivity between vancomycin, dalbavancin, and other glycopeptide class agents is warranted. Disclosures Kerry O.

Abstract Introduction Maintaining abstinence through the opioid withdrawal period is a substantial barrier to treatment for patients with opioid use disorder. The alpha-2 agonist lofexidine has demonstrated efficacy and safety in clinical trials, but pragmatic studies describing its use in clinical practice are lacking. This case series describes the use of lofexidine for opioid withdrawal symptoms in an inpatient addiction treatment facility. Methods Seventeen patients receiving at least 1 dose of lofexidine during inpatient treatment for opioid withdrawal were included in this study. A retrospective chart review was conducted for clinical, subjective, and objective data. Adverse events, total daily dose, clinical opioid withdrawal scale (COWS) scores, vital signs, and reasons for early discontinuation of lofexidine are reported. Results Patients treated with lofexidine experienced mild withdrawal symptoms throughout treatment. Most patients (65%) experienced a decrease in their average daily COWS scores from intake to discharge. Two patients (12%) left treatment against medical advice, and 5 patients (29%) discontinued treatment prior to day 7 due to resolution of symptoms. Average daily blood pressure readings remained stable, and daily average heart rate decreased over time. Discussion Lofexidine can be successfully incorporated into a conventional withdrawal management protocol. The cost of lofexidine and its recent introduction to the market remain barriers to accessibility in the United States. Studies evaluating patient-reported outcomes as well as direct comparisons with other alpha-2 agonists are needed to inform optimal clinical use of lofexidine.

Introduction At Wake Forest Baptist Health, an adult tumor lysis syndrome pocket card was created in order to optimize management of tumor lysis syndrome and outline specific recommendations for the use of rasburicase. Due to the increased use of rasburicase at our institution and its cost, the purpose of this study was to evaluate the utilization of rasburicase for the management of tumor lysis syndrome in pediatric and adult patients in the inpatient and outpatient settings. Methods This was an observational, single-center, non-randomized, retrospective chart review conducted between September 2018 and August 2019. The primary objective was to evaluate the utilization of rasburicase and appropriateness for the management of tumor lysis syndrome in pediatric and adult patients based on the Wake Forest Baptist Health tumor lysis syndrome pocket card. The secondary objectives were to assess response to prophylactic and treatment doses of rasburicase and to quantify drug cost versus expense of rasburicase utilization. Results Overall, 64 patients (57 adults and 7 pediatric patients) were included in the study. Rasburicase use for tumor lysis syndrome indication adhered to the pocket card 64% of the time. Appropriate fluids and/or allopurinol were initiated in only 34% of patients. For monitoring, 80% of patients had all necessary tumor lysis syndrome laboratory values collected after rasburicase administration. All 11 patients (17%) who received rasburicase in the outpatient setting did not have follow-up labs collected. Of the patients who had tumor lysis syndrome laboratory values collected post rasburicase, 39% were appropriately timed to accurately assess efficacy of rasburicase with the median time of laboratory monitoring after rasburicase being 6.5 h. Response was observed with rasburicase 3 mg (92%), 6 mg (100%), and weight-based dosing (100%). The wholesale acquisition cost per patient was $5203 (1101–10,406). The potential cost savings of using the 3 mg dose versus the 6 mg dose for the patients who did not meet tumor lysis syndrome treatment recommendations based on the Wake Forest Baptist Health pocket card was estimated to be $36,419.46. Conclusion There are several opportunities for improvement in tumor lysis syndrome management and rasburicase utilization at our institution. This study will lead to the implementation of formal restrictions for rasburicase use and selection of rasburicase dose. Updating the rasburicase order panel to include appropriate prophylaxis and require input of uric acid level, populating pertinent tumor lysis syndrome laboratory values on the order verification screen for pharmacists to appropriately assess if rasburicase meets the institution restriction criteria, and providing education to providers on the appropriate ordering and timing of labs.

OBJECTIVE: This study was conducted to evaluate direct oral anticoagulants (DOACs) prescribed to elderly patients in an outpatient setting, specifically evaluating if Food and Drug Administration (FDA) -approved dosing recommendations are followed.<br/> DESIGN: This study was a retrospective quality improvement project.<br/> SETTING: This study was conducted at geriatric hospital-based primary care clinics at the University of Pittsburgh Medical Center (UPMC), UPMC Senior Care Institute and UPMC Benedum Geriatric Center.<br/> PATIENTS: Subjects included were 65 years of age or older; had an office visit at UPMC Senior Care Institute or UPMC Benedum Geriatric Center from September 1, 2015, to August 31, 2017; and had a DOAC on their home medications.<br/> INTERVENTIONS: Data were obtained through retrospective chart review.<br/> MAIN OUTCOME MEASURE: The primary objective of the study was to evaluate the appropriateness of dosing of DOACs based on FDA-labeled recommendations.<br/> RESULTS: Of 232 patients included in analysis, 42.7% were found to have dosing inconsistent with FDAlabeled recommendations (47.3% apixaban, 35.8% rivaroxaban, and 31.6% dabigatran). No patients were prescribed edoxaban. The majority (72.7%) were dosed lower than FDA-recommended doses. Of all patients, the most frequent parameter (54.5%) for inappropriate dosing was patients meeting only 1 of 3 dose-reduction criteria when prescribed reduced-dose apixaban. Geriatrician and nongeriatrician prescribers had similar rates of prescribing DOACs with doses inconsistent with FDA-labeled recommendations (44.0% vs. 40.8%; P = 0.62).<br/> CONCLUSION: Results suggest that DOACs used in outpatient geriatric patients are frequently dosed inconsistent with FDA-approved dosing recommendations. Further research is needed regarding clinical outcomes in older patients receiving DOACs and in those with dose adjustments inconsistent with FDA-labeled recommendations.<br/>

Abstract Background Gastrointestinal manifestations are commonly seen in COVID-19 disease with up to 50% of patients reporting nausea or diarrhea. Cholecystitis has been described in rare cases related to COVID-19, possibly in consequence of immune activation, but biliary disease from SARS-CoV-2 infection is not well described. We examined a case series of patients with both COVID-19 and cholecystitis at our institution. Methods We performed a retrospective chart review of all patients with a diagnosis of cholecystitis within 3 months of SARS-CoV-2 infection; looking at clinical, laboratory, and radiographic characteristics of this population. Results 30 individuals were identified with a diagnosis of cholecystitis within 3 months of diagnosis of SARS-CoV-2 infection. Most patients presenting with cholecystitis were female and obese (see Table 1). 14 individuals were diagnosed with SARS-CoV-2 infection during the same presentation as their cholecystitis diagnosis, usually as part of pre-operative screening. Of 16 individuals diagnosed with SARS-CoV-2 prior to their cholecystitis presentation, a mean of 24 and 17 days elapsed between SARS-CoV-2 infection and cholecystitis symptom onset and radiographic diagnosis, respectively (see Figure 1). Most of these patients had mild respiratory disease, with only 9 developing an oxygen requirement, and only 3 requiring mechanical ventilation. While 17 patients were treated surgically for their cholecystitis, this did not appear to impact symptom resolution. Table 1. Patient Characteristics Figure 1. Time between COVID-19 and Cholecystitis Conclusion Cholecystitis may be an uncommon complication of COVID-19 disease. Cholecystitis may manifest most often 2-4 weeks following SARS-CoV-2 infection. This timing is similar to that in Multisystem Inflammatory Syndrome following SARS-CoV-2 infection and given similarities in timing to we hypothesize that cholecystitis in our patients could be driven by immune activation.

AbstractObjectiveB vitamins are essential for the functioning of the nervous system. Vitamin B1 (thiamine) deficiency is associated with neuropsychiatric syndromes such as Wernicke's encephalopathy (WE), which, if untreated, has an estimated mortality of 17–20%. Although the prevalence of thiamine deficiency in the general population is difficult to estimate, it is being increasingly recognized in oncology, especially in the inpatient setting. We describe three cases of thiamine deficiency (TD) in the outpatient psychiatric oncology setting.MethodRetrospective chart review of three adult patients, who were seen in the psychiatric oncology clinic and found to have TD on laboratory testing, was done. Patient, disease, and thiamine treatment-related information were obtained, and descriptive statistics were used to analyze the data.ResultsThe average age was 59 years, mean body mass index (BMI) was 22.00 ± 4.58 (mean ± SD), and mean thiamine level was 59.10 ± 7.69 that ranged from 45 to 68 nmol/L (normal thiamine level reference: 70–180 nmol/L). None of the patients had brain imaging nor cerebrospinal fluid analysis. Risk factors such as unbalanced nutrition, prior GI surgery, renal disease, and chemotherapy were noted.Significance of resultsTD can have a multifactorial etiology in oncology. Identification of TD in both inpatient and outpatient setting is important. Our report highlights how early identification of TD in the outpatient setting can help prevent further clinical progression.

Background: Previous Level I studies show promising results for the use of a hydrogel synthetic cartilage implant (SCI) for the treatment of hallux rigidus. A recent independent retrospective review has put those results into question, however. The purpose of this article is to report patient-reported outcomes and early complications using this implant so as to add to the paucity of data in the literature regarding this implant. Methods: This was a retrospective chart review of patients undergoing hydrogel synthetic cartilage implant for the treatment of hallux rigidus from July 2017 to November 2018. Data collected included patient demographics, radiographic grading, and outcomes: Veterans Rand 12 Item Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS), patient satisfaction, and complications. Fifty-four patients (59 feet) with an average age of 57.6 (range, 39-78) years were analyzed. The average latest follow-up was 18.9 (range, 3-31.3) months. Body mass index was 26.7 (range, 18.7-35.2). None were diabetic and 5 were smokers. Results: The mean outcome improvements were 6.5 points (VR-12 Physical), 17.2 points (FAAM ADL), 27.4 points (FAAM Sport), and 18.4 points (VAS) ( P < .01 for each). Scores were significantly improved from preoperatively to most recent follow-up for FAAM ADL (71.0 vs 88.2 points), FAAM Sports (44.6 vs 72.0 points), and VAS (49.4 vs 31.0) ( P < .01). Overall, 72.5% patients would definitely or probably have the operation again. Ten patients (18.5%) went on to have revision surgery. Of these, 7 patients were revised to an arthrodesis, and 1 metal hemiarthroplasty and 2 implants were removed because of infection. Conclusion: Synthetic cartilage implantation for the treatment of hallux rigidus demonstrated improved pain and outcome scores at short-term follow-up. Reoperation and conversion to fusion rates were comparable to prior studies. Level of Evidence: Level IV, case series.

Abstract Background and purpose Patients with focal cartilage lesions experience functional impairment. Results for biological treatments in the middle-aged patient is poor. Previous studies with focal prosthetic inlay resurfacing have shown a higher risk of conversion to total knee replacement at mid-term follow-up. A novel customized implant (Episealer, Episurf, Stockholm, Sweden) has been proposed to improve implant positioning and survival. The primary objective was to assess subjective-, objective function and implant survival at a minimum of five years after surgery. Materials and methods The inclusion criteria were patients aged 30–65 years with symptomatic focal chondral defects in the medial femoral condyle, International Cartilage Research Society grade 3 or 4 and failed conservative or surgical treatment. Minimum follow-up of 5 years. Clinical and radiologic assessments were made. Patient-reported outcome measurements at the latest follow-up were compared with the baseline data for the Knee injury and Osteoarthritis Outcome Score (KOOS), the EuroQoL (EQ-5D), the Tegner Activity Scale and a Visual Analog Scale of pain (VAS 0–10). Results Ten patients with the mean follow-up period of 75 months (60–86 months, SD 10) were included. Signs of osteoarthritis were seen in one patient (Ahlbäck 1). No cases with revision to knee replacement. VAS for pain and KOOS showed improvements that reached significance for VAS (p ≤ 0.001) and the KOOS subscores Pain (p = 0.01), ADL (p = 0.003), Sport and Recreation (p = 0.024) and Quality of Life (p = 0.003). Conclusion A good subjective outcome, a low risk of progression to degenerative changes and the need for subsequent surgery were seen at the mid-term follow-up with this customized focal knee-resurfacing implant. Level of evidence Prospective case series, level 4.

Purpose: To compare pain assessment documentation postopioid administration in hospitalized patients before and after implementing nurse education. Methods: Patients 18 years and older were randomly selected for inclusion if they received 1 opioid dose while admitted to the hospital. Through retrospective chart review, opioid data, including date and time, were collected for each opioid administered. Pain score data, including time and date of documentation, were recorded for analysis. The primary objective of this study was to determine whether a nursing education intervention would improve documentation of pain scores within an appropriate time frame postadministration of an opioid medication. The intervention was a training presentation uploaded to the institution’s intranet with an assessment. The primary outcome was measured by comparing the frequency by which nurses documented pain scores following opioid administration before and after education. Results: Three hundred twenty patients (160 patients per time period) were evaluated. The percentage of pain scores recorded within the appropriate assessment time following opioid administration increased from 32.9% to 37.8% ( P = .003). The proportion of appropriate pain score documentation increased 4.9% (95% confidence interval [CI]: 1.6%-8.2%). Conclusion: An increase in the documentation of efficacy assessments after opioid administration was demonstrated after nursing education. Further studies should be done to identify additional strategies to increase monitoring as well as to identify a benchmark for institutions with regard to pain management monitoring.

Abstract Background Recent changes to vancomycin guidelines recommend dosing by targeting an AUC of 400-600 in most patients, due to similar effectiveness and reduced rates of acute kidney injury (AKI). AKI was defined as an increase in serum creatinine of ≥ 0.5 mg/dl, a 50% increase in serum creatinine from baseline on two consecutive readings, or a decrease in creatinine clearance from 50% from baseline on two consecutive readings. The purpose of this study was to assess the incidence of AKI in patients receiving vancomycin dosed by AUC based trough goals and vancomycin dosed by traditional trough goals (15-20 mcg/mL) in the outpatient setting. Methods This study was performed by retrospective chart review using the electronic health record. Patients receiving vancomycin outpatient as continuation of therapy after discharge from December 1, 2018 through March 24, 2021 were reviewed. The primary objective was incidence of AKI in patients receiving vancomycin outpatient with trough goals derived from patient specific AUC calculations compared to patients receiving vancomycin by traditional goal troughs. Secondary objectives included rate of treatment failure, average AUC estimated trough range, and number of regimen changes required. Results There were a total of 65 patients in the traditional trough dosing group and 53 patients in the AUC trough dosing group. The incidence of AKI was higher in the traditional trough dosing group compared to the AUC trough group (23.1% vs 5.7%; p=0.01). There were no differences in incidence of treatment failure. The mean AUC estimated trough range was 11.4-16.9 mcg/mL. There were significantly less average regimen changes required in the AUC dosing group (1.64 vs 1.13; p=0.006). Patients receiving AUC trough dosing were 78% less likely to develop AKI as patients receiving traditional trough dosing (HR 0.221, 95%CI 0.051 – 0.968). Conclusion There was a significantly lower incidence of AKI in patients receiving vancomycin dosed by AUC based troughs compared to traditional trough dosing. Continuing AUC trough based dosing for vancomycin in the outpatient setting is convenient and may lead to reduced rates of AKI. Disclosures Dustin R.

Background: Although considered a tropical disease, strongyloidiasis may be encountered in non-endemic regions, primarily amongst immigrants and travelers from endemic areas.  Chronic strongyloides infection may be under-detected owing to its non-specific cutaneous presentation and the low sensitivity of commonly used screening tools. Methods: 18 consecutive patients with serologic evidence of strongyloides infestation who presented to a single urban, academic dermatology clinic between September 2013 and October 2016 were retrospectively included.  Patient age, sex, country of origin, strongyloides serology titer, absolute eosinophil count, presenting cutaneous manifestations, and patient reported subjective outcome of pruritus after treatment were obtained via chart review.  Results: Of the 18 patients, all had non-specific pruritic dermatoses, 36% had documented eosinophila and none were originally from the United States. A majority reported subjective improvement in their symptoms after treatment. Conclusion:  Strongyloides infection and serologic testing should be considered in patients living in non-endemic regions presenting with pruritic dermatoses and with a history of exposure to an endemic area.Key Points:Chronic strongyloidiasis can be encountered in non-endemic areas and clinical manifestations are variableEosinophilia was not a reliable indicator of chronic infection in this case series Dermatologists should consider serologic testing for strongyloidiasis in patients with a history of exposure and unexplained pruritus
