Factors Affecting Dilation Interval in Patients With Granulomatosis With Polyangiitis-Associated Subglottic and Glottic Stenosis

Objective Subglottic stenosis (SGS) is a known complication of granulomatosis with polyangiitis (GPA). We investigated the impact of medical and surgical interventions on the surgical dilation interval and characterized patients with glottic involvement. Study Design A retrospective chart review of patients with GPA-associated SGS was performed from 2010 to 2019. Setting Tertiary academic medical center. Methods The impact of medical and surgical interventions on dilation interval was assessed. The prevalence of glottic involvement was assessed, and clinical characteristics and outcomes were compared with patients without glottic involvement. Results A total of 39 patients with GPA-associated SGS were analyzed. Dilation intervals in patients receiving leflunomide (n = 4; median, 484 days; 95% CI, 405-1099) were greater than in those not receiving leflunomide (median, 155 days; 95% CI, 48-305; P = .033). The surgical technique used did not affect dilation interval. Patients with glottic involvement (n = 13) had a greater incidence of dysphonia (13/13 vs 15/26 [58%], P = .007) and a shorter dilation interval with involvement (median, 91 days; interquartile range, 70-277) versus without involvement (median, 377 days; interquartile range, 175-1148; hazard ratio, 3.38; 95% CI, 2.26-5.05; P < .001). Of 13 patients, 8 (62%) did not have glottic involvement on first presentation. Conclusion Although GPA is classically thought to affect the subglottis, it also involves the glottis in a subset of patients. These patients have greater complaints of dysphonia and require more frequent surgery. Systemic therapy may increase dilation intervals. In this preliminary study, patients taking leflunomide demonstrated an improvement, highlighting the need for further study of immunosuppression regimens in the treatment of GPA-associated SGS.

Background. Recent studies of risks in cardiopulmonary arrest (CPA) have been performed using large databases from a broad mix of hospital settings. However, these risks might be different in a large, urban, academic medical center. We attempted to validate factors influencing outcomes from CPA at the University of Maryland Medical Center (UMMC). Methods. Retrospective chart review of all adult patients who underwent CPA between 2000 and 2005 at UMMC. Risk factors and outcomes were analyzed with appropriate statistical analysis and compared with published results. Results. 729 episodes of CPA were examined during the study period. Surgical patients had better survival than medical or cardiac patients. Intensive care unit' (ICU) patients had poor survival, but there was no difference on monitored or unmonitored floors. Respiratory etiologies survived better than cardiac etiologies. CPR duration and obesity were negatively correlated with outcome, while neurologic disease, trauma, and electrolyte imbalances improved survival. Age, gender, race, presence of a witness, presence of a monitor, comorbidities, or time of day of CPA did not influence survival, although age was associated with differences in comorbidities. Conclusions. UMMC risk factors for CPA survival differed from those in more broad-based studies. Care should be used when applying the results of database studies to specific medical institutions.

Abstract Background The new ASHP/IDSA consensus guidelines recommend area under the curve (AUC) monitoring to optimize vancomycin therapy. Little is known about the ability to implement this recommendation in a real-world setting. At UMass Memorial Medical Center (UMMMC), an AUC pharmacy to dose protocol was created to manage infectious diseases (ID) consult patients on vancomycin. The service was piloted by the pharmacy residents and 2 clinical pharmacists. The purpose of this study was to determine if a pharmacy to dose AUC protocol can safely and effectively be implemented. Methods A first-order kinetics calculator was built into the electronic medical record and live education was provided to pharmacists. Pharmacists ordered levels, wrote progress notes, and communicated to teams regarding dose adjustments. Patients were included based upon ID consult and need for vancomycin. After a 3-month implementation period, a retrospective chart review was completed. Patients in the pre-implementation group were admitted 3 months prior to AUC pharmacy to dose, had an ID consult and were monitored by trough (TR) levels. The AUC group was monitored with a steady state peak and trough level to calculate AUC. The primary outcome evaluated time to goal AUC vs. time to goal TR. Secondary outcomes included number of dose adjustments made, total daily dose of vancomycin, and incidence of nephrotoxicity. Results A total of 64 patients met inclusion criteria, with 37 patients monitored by TR and 27 patients monitored by AUC. Baseline characteristics were similar except for weight in kilograms (TR 80.0 ±25.4 vs AUC 92.0 ±26.7; p=0.049). The average time to goal AUC was 4.13 (±2.08) days, and the average time to goal TR was 4.19 (±2.30) days (p=0.982). More dose adjustments occurred in the TR group compared to the AUC (1 vs 2; p=0.037). There was no difference between the two groups in dosing (TR 15.8 mg/kg vs AUC 16.4 mg/kg; p=0.788). Acute kidney injury occurred in 5 patients in the AUC group and 11 patients in the TR group (p=0.765). Conclusion Fewer dose adjustments and less nephrotoxicity was seen utilizing an AUC based protocol. Our small pilot has shown that AUC pharmacy to dose can be safely implemented. Larger studies are needed to evaluate reduction in time to therapeutic goals. Disclosures All Authors: No reported disclosures

The Impact

Background: Stethoscopes are a known vector for microbial transmission; however, common strategies used to clean stethoscopes pose certain barriers that prevent routine cleaning after every use. We aimed to determine whether using readily available alcohol-based hand rub (ABHR) would effectively reduce bacterial bioburden on stethoscopes in a real-world setting. Methods: We performed a randomized study on inpatient wards of an academic medical center to assess the impact of using ABHR (AlcareExtra; ethyl alcohol, 80%) on the bacterial bioburden of stethoscopes. Stethoscopes were obtained from healthcare providers after routine use during an inpatient examination and were randomized to control (no intervention) or ABHR disinfection (2 pumps applied to tubing and bell or diaphragm by study personnel, then allowed to dry). Cultures of the tubing and bell or diaphragm were obtained with premoistened cellulose sponges. Sponges were combined with 1% Tween20-PBS and mixed in the Seward Stomacher. The homogenate was centrifuged and all but ~5 mL of the supernatant was discarded. Samples were plated on sheep’s blood agar and selective media for clinically important pathogens (CIPs) including S. aureus, Enterococcus spp, and gram-negative bacteria (GNB). CFU count was determined by counting the number of colonies on each plate and using dilution calculations to calculate the CFU of the original ~5 mL homogenate. Results: In total, 80 stethoscopes (40 disinfection, 40 control) were sampled from 46 physicians (MDs) and MD students (57.5%), 13 advanced practice providers (16.3%), and 21 nurses (RNs) and RN students (26.3%). The median CFU count was ~30-fold lower in the disinfection arm compared to control (106 [IQR, 50–381] vs 3,320 [986–4,834]; P < .0001). The effect was consistent across provider type, frequency of recent usual stethoscope cleaning, age, and status of pet ownership (Fig. 1). Overall, 26 of 80 (33%) of stethoscopes harbored CIP. The presence of CIP was lower but not significantly different for stethoscopes that underwent disinfection versus controls: S. aureus (25% vs 32.5%), Enterococcus (2.5% vs 10%), and GNB (2.5% vs 5%). Conclusions: Stethoscopes may serve as vectors for clean hands to become recontaminated immediately prior to performing patient care activities. Using ABHR to clean stethoscopes after every use is a practical and effective strategy to reduce overall bacterial contamination that can be easily incorporated into clinical workflow. Larger studies are needed to determine the efficacy of ABHR at removing CIP from stethoscopes as stethoscopes in both arms were frequently contaminated with CIP. Prior cleaning of stethoscopes on the study day did not seem to impact contamination rates, suggesting the impact of alcohol foam disinfection is short-lived and may need to be repeated frequently (ie, after each use).Funding: NoneDisclosures: NoneDisclosures: NoneFunding: None

Background: There is conflicting evidence concerning the obesity paradox in stroke patients. We sought to examine the relationship between gender, BMI, and prevalence of comorbidities in patients with non-hemorrhagic stroke. Materials and Methods: Retrospective chart review was performed in 996 consecutive patients treated for non-hemorrhagic stroke at a single academic medical center. Patients were divided according to gender and specific BMI groups according to the National Institute of Health. This study was approved by the institutional IRB. Results: Patients with BMI from 0-18.5 and 18.5-24.9 were more likely to be female (63.2% and 58.4% p<.05). Whereas patients with BMI over 25-30 and 30-35 were more likely to be male (60.82% and 59.2% p<.05). Morbidly obese patients (BMI>35) were equally likely to be men or women. In men higher BMI correlated with presentation at younger age. Diabetes was most prevalent in patients with BMI over 35 (40% males, 44% females, p<.05). In females, HTN was associated with BMI 30-34.5 and 35+ (80.5% and 73.3%, P<.05). Males showed a similar though non-significant trend. The prevalence of end stage renal disease, systemic atherosclerosis, and PVD was not significantly correlated with BMI in either gender. Conclusion: Gender and BMI significantly affect associated comorbidities in patients with non-hemorrhagic stroke, possibly suggestive of unique gender specific disease mechanisms. Additional studies investigating the effect of gender and BMI on diagnostic evaluation and treatment of patients with non-hemorrhagic stroke are warranted.

Abstract Background Inpatient antibiotic use early on in the COVID-19 pandemic may have increased due to the inability to distinguish between bacterial and COVID-19 pneumonia. The purpose of this study was to determine the impact of COVID-19 on antimicrobial usage during three separate waves of the COVID-19 pandemic. Methods We conducted a retrospective review of patients admitted to Detroit Medical Center between 3/10/19 to 4/24/21. Median days of therapy per 1000 adjusted patient days (DOT/1000 pt days) was evaluated for all administered antibiotics included in our pneumonia guidelines during 4 separate time periods: pre-COVID (3/3/19-4/27/19); 1st wave (3/8/20-5/2/20); 2nd wave (12/6/21-1/30/21); and 3rd wave (3/7/21-4/24/21). Antibiotics included in our pneumonia guidelines include: amoxicillin, azithromycin, aztreonam, ceftriaxone, cefepime, ciprofloxacin, doxycycline, linezolid, meropenem, moxifloxacin, piperacillin-tazobactam, tobramycin, and vancomycin. The percent change in antibiotic use between the separate time periods was also evaluated. Results An increase in antibiotics was seen during the 1st wave compared to the pre-COVID period (2639 [IQR 2339-3439] DOT/1000 pt days vs. 2432 [IQR 2291-2499] DOT/1000 pt days, p=0.08). This corresponded to an increase of 8.5% during the 1st wave. This increase did not persist during the 2nd and 3rd waves of the pandemic, and the use decreased by 8% and 16%, respectively, compared to the pre-COVID period. There was an increased use of ceftriaxone (+6.5%, p=0.23), doxycycline (+46%, p=0.13), linezolid (+61%, p=0.014), cefepime (+50%, p=0.001), and meropenem (+29%, p=0.25) during the 1st wave compared to the pre-COVID period. Linezolid (+39%, p=0.013), cefepime (+47%, p=0.08) and tobramycin (+47%, p=0.05) use remained high during the 3rd wave compared to the pre-COVID period, but the use was lower when compared to the 1st and 2nd waves. Figure 1. Antibiotic Use 01/2019 to 04/2019 Conclusion Antibiotics used to treat bacterial pneumonia during the 1st wave of the pandemic increased and there was a shift to broader spectrum agents during that period. The increased use was not sustained during the 2nd and 3rd waves of the pandemic, possibly due to the increased awareness of the differences between patients who present with COVID-19 pneumonia and bacterial pneumonia.

Stroke Trial

Introduction: Because “time is brain,” acute stroke trials are increasingly migrating to the prehospital setting. However, some study therapies are ill-suited for paramedic, prehospital delivery, including fibrinolytics, endovascular therapies, and surgical interventions. Best scientific and regulatory practice does not permit one patient to participate in two different therapeutic trials simultaneously. The potential reduction in enrollment in post-arrival trials due to earlier recruitment in a prehospital trial has not been well delineated. Methods: We analyzed all patients recruited into acute stroke trials at an academic medical center (AMC) from Jan 2005 - Dec 2012. Throughout this period, the AMC was participating in a prehospital treatment trial (NIH FAST-MAG trial), as well as diverse concurrent post-arrival acute trials. Results: During the 96 month study period, in addition to the prehospital trial, the AMC participated in 26 other acute, post-arrival stroke trials, 25 for ischemic stroke and 1 for intracerebral hemorrhage. Length of participation in each post-arrival trial varied, but at all times throughout the study period, the AMC was recruiting for at least 3 concurrent post-arrival acute trials. During this time, a total of 200 patients were enrolled in acute stroke trials, including 98 (49%) in FAST-MAG and 102 (51%) in concurrent, post-arrival acute trials. Among the patients enrolled in FAST-MAG, 67% were not eligible for any concurrent trial. Among the 33% eligible for a concurrent trial, 15% were eligible for 1, 7% for 2, 7% for 3, and 3% for 4. Of the 134 patients eligible for post-arrival trials, 102 (76%) were enrolled in post-arrival trials and 32 (24%) in FAST-MAG. Leading reasons that FAST-MAG patients were ineligible for post-arrival trials included: NIHSS too low (23.4%), intracranial hemorrhage (17.9%), deficit resolved to TIA (9.2%), IV tPA used in standard management (9.0%), NIHSS too high (7.1%), and age too high (5.2%). Conclusions: A prehospital hyperacute stroke trial with wide entry criteria reduced only modestly, by one-fourth, enrollment into concurrently active, post-arrival stroke trials. Simultaneous performance of prehospital and ED-based acute stroke trials in research networks is highly feasible.

Introduction: COVID-19 has significantly impacted hospital systems worldwide. The impact of statewide stay-at-home mandates on echocardiography volumes is unclear. Methods: We queried our institutional echocardiography database from 6/1/2018 to 6/13/2020 to examine rates of transthoracic (TTE), stress (SE), and transesophageal echocardiograms (TEE) prior to and following the COVID-19 Massachusetts stay-at-home order on March 15, 2020. Results: Among 36,377 total studies performed during the study period, mean weekly study volume dropped from 332 + 3 TTEs/week, 30 + 1 SEs/week, and 21 + 1 TEEs/week prior to the stay-at-home order (6/1/2018-3/15/2020) to 158 + 13 TTEs/week, 8 + 2 SEs/week, and 8 + 1 TEEs/week after (% change, -52%, -73%, and -62% respectively, all p < 0.001 when comparing volume prior to March 15 versus after). Weekly TTEs correlated strongly with hospital admissions throughout the study period (r = 0.93, 95% CI 0.89-0.95, p < 0.001) ( Figure ). Outpatient TTEs declined more than inpatient TTEs (% change, -74% vs. -39%, p <0.001). As of 3 weeks following the cessation of the stay-at-home order, TTE, SE, and TEE weekly volumes have increased to 73%, 66%, and 81% of pre-pandemic levels, respectively. Conclusions: Echocardiography volumes fell precipitously following the Massachusetts stay-at-home order, strongly paralleling declines in overall hospitalizations. Outpatient TTEs declined more than inpatient TTEs. Despite lifting of the order, echocardiography volumes remain substantially below pre-pandemic levels. The impact of the decreased use of echocardiographic services on patient outcomes remains to be determined.

Cushing disease is a relatively rare cause of Cushing syndrome secondary to a hyperfunctioning pituitary adenoma. In addition to signs and symptoms of hypercortisolism, Cushing disease may present with diverse otolaryngic manifestations, which may guide diagnosis and management. We performed a retrospective chart review of patients who were found to have Cushing disease and who underwent transnasal transsphenoidal surgery for pituitary adenomas between January 1, 2007, and July 1, 2014, at a tertiary academic medical center. There were 37 consecutive patients in this series with Cushing disease caused by a pituitary adenoma. Fifteen (41%) patients complained of visual changes. Five (14%) patients suffered from obstructive sleep apnea. Four (11%) patients had thyroid disease. Other symptoms included hearing loss, vertigo, tinnitus, epistaxis, dysphagia, and salivary gland swelling. Although Cushing disease traditionally presents with classic “Cushingoid” systemic features, it also may present with various otolaryngic manifestations. A thorough workup by otolaryngologists is critical in the comprehensive management of these patients.

Training Opportunities

ABSTRACT Background Training residents to become competent in common bedside procedures can be challenging. Some hospitals have attending physician–led procedure teams with oversight of all procedures to improve procedural training, but these teams require significant resources to establish and maintain. Objective We sought to improve resident procedural training by implementing a resident-run procedure team without routine attending involvement. Methods We created the role of a resident procedure coordinator (RPC). Interested residents on less time-intensive rotations voluntarily served as RPC. Medical providers in the hospital contacted the RPC through a designated pager when a bedside procedure was needed. A structured credentialing process, using direct observation and a procedure-specific checklist, was developed to determine residents' competence for completing procedures independently. Checklists were developed by the residency program and approved by institutional subspecialists. The service was implemented in June 2016 at an 850-bed academic medical center with 70 internal medicine and 32 medicine-pediatrics residents. The procedure service functioned without routine attending involvement. The impact was evaluated through resident procedure logs and surveys of residents and attending physicians. Results Compared with preimplementation procedure logs, there were substantial increases postimplementation in resident-performed procedures and the number of residents credentialed in paracenteses, thoracenteses, and lumbar punctures. Fifty-nine of 102 (58%) residents responded to the survey, with 42 (71%) reporting the initiative increased their ability to obtain procedural experience. Thirty-one of 36 (86%) attending respondents reported preferentially using the service. Conclusions The RPC model increased resident procedural training opportunities using a structured sign-off process and an operationalized service.
