Abstract
235 Background: Physician burnout affects over 50% of physicians in the US and is related to the high workload and loss of anonymity. The result is physical exhaustion, moral distress, and increased rates of suicide. At our institution, burnout was identified in 42.1% of providers & 55.6% of staff surveyed using AMA/ASCO burnout questionnaires with treatment delays in the infusion center (IC) implicated as the biggest culprit. Methods: We tracked causes of delay in starting chemotherapy in the IC and utilizing Pareto Chart identified that over 80% of delays were due to missing chemotherapy orders on the day of IC appointment. Process flow charts for providers noted significant variations in practices. Retrospective chart review, 6/21/2019 to 8/30/ 2019, revealed that an average of 13.18% of patients scheduled to receive chemotherapy at the IC had missing orders on the day of the infusion, resulting in up to a 111-minute delay in starting chemotherapy. We set out to sustainably decrease the number of missing chemotherapy orders in the IC by 50%, decreasing the resultant stress on providers and IC nurses. Results: Four interventions were implemented over 2 plan-study-do-act (PDSA) cycles and resulted in decreasing the average number of missing orders on the day of IC appointment to 7% achieving our aim (Table). To ensure sustainability of results, we continued the interventions and maintained faculty engagement via periodic updates. Sustainability analysis revealed that the median number of patients with missing orders between 12/2/2019 and 2/28/2020 remained at 5% effectively achieving our goal. The effects of this intervention on physician/staff burnout will be reassessed after 1 year of intervention implementation using the same AMA/ASCO burnout questionnaires. Conclusions: Systematically standardizing a process achieves a sustainable impact, promotes a more effective workplace environment and decreases burnout on physicians and staff. [Table: see text]

Abstract
PURPOSE/OBJECTIVES Silver diamine fluoride (SDF) is a promising therapy for arresting and preventing caries in difficult to treat, high-risk populations, including institutionalized older adults. This study investigates the knowledge and perceptions about SDF of graduating dental students in multiple U.S. dental schools, as well as their willingness to use SDF in their practices. METHODS A survey was designed consisting of 21 total questions: 6 questions regarding students' demographic information and their SDF content exposure contextualization, 8 questions tailored to investigate 2 domains regarding students' knowledge about SDF (properties and indication), and 7 questions aiming to investigate 3 domains regarding students' perceptions about SDF (SDF usefulness, appropriateness of using SDF, and willingness to use SDF when in private practice). The survey was then distributed to graduating dental students at 7 U.S. dental schools. RESULTS A total of 386 surveys (response rate of 55%) was collected from 7 schools in the Spring of 2019. The median score resulting from the SDF content exposure questions was 3 (SD = 1.43) from a range of 0-5. The median score from knowledge about SDF properties was 4 (SD = 1.18) from a range of 0 to 6. In the multivariate analysis, a linear model found that the covariates "SDF Usefulness", "SDF Appropriateness" and "SDF Patient Willingness to Use" were significantly associated with higher student willingness to use SDF (R2 = 0.395). CONCLUSION The results indicated that the graduating students have a positive perception of SDF regarding its usefulness and appropriateness. Graduating students appear inclined to utilize SDF upon entering private practice.

Abstract
e19246 Background: Physician burnout is affecting over 50% of physicians in the US alone and is related to the high workload, loss of anonymity and a sense of powerlessness in the face of multiple bureaucratic hurdles. The result is physical exhaustion, moral distress, high turnover and increased rates of suicide. Methods: The faculty and staff at Washington Cancer Institute (WCI) were surveyed using AMA/ASCO burnout questionnaire to identify burnout rates. A brainstorming session with staff captured the perceived causes of burnout in a fishbone diagram, and the most prominent cause was noted to be pertaining to delays in the infusion center (IC) related to chemotherapy orders. We tracked causes of delay in starting chemotherapy from 7/23/19 to 8/7/19, and utilizing a Pareto Chart identified that over 80% of the delays were due to missing chemotherapy orders on the day of IC appointment. Process flow charts were developed for all provider teams at WCI noting variations that may be leading to delays. The aim was to decrease the number of missing chemotherapy orders for patients coming to the IC by 50%, decreasing the resultant stress on providers and IC nurses. Results: By retrospective chart review, 6/21/2019 to 8/30/ 2019, an average of 13.18% of patients scheduled to receive chemotherapy at WCI IC had missing orders on the day of the infusion, which resulted in up to a 111-minute delay in starting chemotherapy. This, in turn, resulted in stress/burnout among 42.1% of providers and 55.6% of supportive staff. To remedy the problem, we implemented 4 interventions over two plan-do-study-act (PDSA) cycles. In the first PDSA cycle the process was standardized to obtain necessary labs 48 hours prior to IC appointment and review and sign orders by 2 pm the day prior to IC appointment. Email notifications were also sent to all providers and nurse navigators regarding missing orders 48 hours prior to IC appointment. In the second PDSA cycle we continued with the previous interventions in addition to addressing pharmacy related delays in releasing premedication if dose adjustments of chemotherapy are needed. In the time period of 10/2/2019 to 11/11/2019, two PDSA cycles were implemented and resulted in a decrease in the average number of missing orders on the day of IC appointment to 7% achieving our aim. Conclusions: Using a systems approach to standardize the process promotes a more effective environment in the work place and decreases burnout on physicians and staff.

Abstract
77 Background: At Monter Cancer Center, we observed that when patients on active intravenous chemotherapy presented to our local ED about 70% arrived during the hours of 8am and 6pm. ED utilization by active chemotherapy patients results in cancer care by providers not familiar with their disease or treatment, increased costs, poor patient experience and potential treatment delays. Our goal was to create 20% reduction in daytime ED utilization, compared to Q4 2018, by patients that received intravenous chemotherapy within 30 days of their ED visit. Methods: Through the ASCO Quality Training program, a multidisciplinary team of frontline staff was formed to create a Process map, Cause and effect diagram and Priority Matrix to develop solutions. Our first PDSA created a simplified criteria to help office secretaries triage urgent and non-urgent calls to providers. This allowed patients with urgent issues to speak to their care team on first call rather than await a callback. In our second PDSA, our treatment room nurses emphasized to patients on their treatment discharge to contact their care team first for symptom management rather than going to the ED. Results: Compared to our baseline, we have seen a 33% decrease in ED utilization by re-educating patients to call us first for symptoms and providing a clear tool to help secretaries triage calls to the care team. Conclusions: Our study shows improving patient access to their oncology care teams can decrease ED utilization, increase cancer center utilization while improving patient safety across multiple disease types.

Abstract
260 Background: The growing number of oral oncolytic therapies (OOTs) necessitates a standardized EMR workflow that integrates pharmacy activities for dispense and patient management and standardizes cycle-1/day-1 (C1D1) documentation. Our practice’s treatment plans contain appropriately timed OOT follow-up activities including labs, physician follow-up visits, and pharmacy calls for toxicity and adherence checks, however complications in prescription fulfillment such as prior authorization, co-pay assistance, or inability of in-practice pharmacy to dispense limit the predictability of C1D1 dates of OOTs. Methods: An EMR query identified patients at a single clinic location of 5-medical oncologists (MDs) for whom oral oncolytic treatment plans were entered from January 1 to June 30, 2018. C1D1 date entered by the MD in the EMR was compared to the pharmacy processing system dispense date. Ten patients were identified, and 10% (1/10) had an accurate C1D1 documented within the EMR. As part of the ASCO Quality Training Program, to improve the accuracy of C1D1 documentation, a new workflow was implemented whereby: (1) a “hold” activity was added to new EMR treatment plans so that C1D1 remained pending until patients had received medication; (2) clinic checkout staff provided patients with information on the in-practice pharmacy and expectations for next steps; (3) pharmacists utilized existing reporting tools to identify newly entered treatment plans and transcribed orders into e-prescriptions sent to our practice pharmacy; (4) the pharmacy workflow ensued with pharmacy staff leading patient engagement, drug counseling; (5) pharmacists confirm C1D1, document within EMR (6) subsequent treatment plan activities were scheduled. Results: Following education and process changes within the clinic and pharmacy, accurate C1D1 documentation occurred in 90% (9/10) of patients initiating OOTs. Conclusions: Including pharmacy fulfillment time in EMR workflow can improve C1D1 documentation accuracy and associated management of OOTs. Education regarding roles and processes of prescribing MDs, pharmacy staff and clinic staff will be required to scale this process improvement throughout the organization.

Abstract
7 Background: ASCO introduced a Quality Training Program (QTP) in 2013 with an aim: train oncology professionals to design, implement and lead successful quality improvement (QI) activities and assume leadership positions to champion culture change in their practices. Methods: The QTP is a formal 6-month program taught by QI faculty and mentored by QI coaches over five days of in-person learning across three sessions, and hands-on learning at the participants’ practices. Sessions include seminars, case examples, and small group exercises. Participants attend in multi-disciplinary teams and focus on a problem they wish to solve in their practice. Scheduled conference calls with QI coaches were held between sessions. Participants complete pre and post QTP surveys (10 point Likert scale; 1 - no knowledge/competence to 10 - complete knowledge/competence) and provide direct written feedback. Results: Since its inception, QTP has had 15 courses (10 domestic and 5 international) with 120 teams and 544 total participants. QTP is led by an 8-member steering group with 16 faculty and coaches. All post-survey items had an increase in knowledge and competence. Each item’s score was calculated as the mean difference between ‘before’ and ‘after’ score. Participants stated increase of 46% to 84%: overall mean increase for knowledge 38% and competence 37%. The greatest increase were: methodology and practical tools to make changes in practice (writing an aim statement, implementing rapid improvement, process analysis tools, and flowcharting the process). Most common suggestion for improvement was allowing more time for the project. Participants are encouraged to write articles and present work in poster and plenary sessions. QTP have led to 7 manuscripts and 21 abstract presentations to national meetings. Six QTP alumni currently are now QI coaches and faculty. Conclusions: The QTP is a successful QI course for oncology professionals who need to measure performance, investigate quality and safety issues, and implement change. It is the only oncology-focused QI training, as all faculty and coaches are providers and QI specialists with oncology experience, making this a unique opportunity. The success will provide further momentum to offer QTP domestically and around the world.

Abstract
Improving patient satisfaction scores has become a key focus of health-care organizations nationwide but can be a struggle for community hospitals with constrained resources, and particularly challenging for hospitalist programs due to provider variance and turnover. Using the framework of appreciative inquiry, we implemented a multipronged intervention including a rounding model whereby hospitalist leaders rounded on patients and relayed commentary back to their hospitalist providers. We communicated positive feedback preferentially over negative feedback to the entire hospitalist group through regular communication. Providers were encouraged to employ best practices including sitting with the patient, reviewing recommendations using teach back, and providing business cards. Scores improved in the physician communication category by approximately 1% annually from fiscal year 2015 through 2018, with our percentile rank improving 35 percentile points during that time. These findings indicate that a multifaceted approach including best practices is associated with improved patient experience regarding communication with physicians.

Abstract
Because standard radiographies are not able to give exact information about the diseased state of the sinuses, 196 children with chronic nasal complaints, aged from 3 to 14 years were examined with computed tomographic scan. The aim of the study was to investigate whether an age-related pattern in the occurrence of rhinosinusitis in children could be found. The patient group was subdivided into six age groups (3 to 4, 5 to 6, 7 to 8, 9 to 10, 11 to 12, and 13 to 14 years). Especially younger children, until the age of 7 to 8 years seem to be prone to inflammatory changes of all their sinuses. In older children, mainly the maxillary sinuses stay frequently involved. Septal deviations occur in 16% of the youngest to 72% in the oldest age group. The occurrence of bullous conchae increases with age too, although less prominently.

Abstract
Despite the efforts, cost, and extensive use of animals for nonclinical research, only a small number of studies have methodically compared findings from animal toxicology studies to those from human clinical trials. Impediments to understanding the translation of nonclinical safety have included the lack of easy access to data and the need for extensive data curation given the diverse terminologies, formats, and data platforms in use. SEND and SDTM study data standards, developed by CDISC and about to become mandated by FDA, can address this and other drug development issues by facilitating access to data in ways that are not currently feasible. A consistent data standard across clinical and nonclinical will discourage the development of data silos, which easily become obstacles to data sharing and maximizing the value of animal and human data. The confluence of rapid scientific advances, increasingly larger quantities of diverse data, technological advances in data mining, and the FDA's requirements for standardized study data create new opportunities for the advancement of drug development and for refinement in the way we use animals.

Abstract
Despite being an established practice in the disabilities service systems, person-centered planning is a relatively new practice in the behavioral health system. As a result, little is known about the barriers that mental health organizations face in implementing person-centered recovery planning (PCRP). To fill this gap, results are presented from a qualitative analysis of nine focus groups at three public mental health organizations in Texas that have been implementing PCRP for at least 2 years. Findings suggest that organizations experienced 12 distinct barriers to PCRP implementation which were categorized into the Consolidated Framework for Implementation Research domains of intervention characteristics, the outer setting, the inner setting, characteristics of individuals, and the implementation process. Half of these 12 barriers fell within the inner setting domain, suggesting that implementation efforts should be flexible and adaptable to organizational culture and context. One-quarter of the barriers fell into the domain of characteristics of individuals involved in the intervention, which further suggests implementation efforts should assess the impact that both staff and consumers have on implementation success.

Abstract
BACKGROUND Approximately one fifth of school-aged children spend a significant portion of their year at residential summer camp, and a growing number have chronic medical conditions. Camp health records are essential for safe, efficient care and for transitions between camp and home providers, yet little research exists regarding these systems. OBJECTIVE To survey residential summer camps for children to determine how camps create, store, and use camper health records. To raise awareness in the informatics community of the issues experienced by health providers working in a special pediatric care setting. METHODS We designed a web-based electronic survey concerning medical recordkeeping and healthcare practices at summer camps. 953 camps accredited by the American Camp Association received the survey. Responses were consolidated and evaluated for trends and conclusions. RESULTS Of 953 camps contacted, 298 (31%) responded to the survey. Among respondents, 49.3% stated that there was no computer available at the health center, and 14.8% of camps stated that there was not any computer available to health staff at all. 41.1% of camps stated that internet access was not available. The most common complaints concerning recordkeeping practices were time burden, adequate completion, and consistency. CONCLUSIONS Summer camps in the United States make efforts to appropriately document healthcare given to campers, but inconsistency and inefficiency may be barriers to staff productivity, staff satisfaction, and quality of care. Survey responses suggest that the current methods used by camps to document healthcare cause limitations in consistency, efficiency, and communications between providers, camp staff, and parents. As of 2012, survey respondents articulated need for a standard software to document summer camp healthcare practices that accounts for camp-specific needs. Improvement may be achieved if documentation software offers the networking capability, simplicity, pediatrics-specific features, and avoidance of technical jargon.

Abstract
Background Identification of species-specific trypanosome molecules is important for laboratory- and field-based research into epidemiology and disease diagnosis. Although Trypanosoma congolense is the most important trypanosome pathogen of cattle in Africa, no species-specific molecules found in infective bloodstream forms (BSF) of the parasites have been identified, thus limiting development of diagnostic tests. Methods Immuno-mass spectrometric methods were used to identify a protein that is recognized by a T. congolense-specific monoclonal antibody (mAb) Tc6/42.6.4. The identified molecule was expressed as a recombinant protein in E. coli and was tested in several immunoassays for its ability to interact with the mAb. The three dimensional structure of the protein was modeled and compared to crystal- and NMR-structures of the homologous proteins from T. cruzi and T. brucei respectively, in order to examine structural differences leading to the different immunoreactivity of the T. congolense molecule. Enzyme-linked immunosorbent assays (ELISA) were used to measure antibodies produced by trypanosome-infected African cattle in order to assess the potential for use of T. congolense calflagin in a serodiagnostic assay. Results The antigen recognized by the T. congolense-specific mAb Tc6/42.6.4 was identified as a flagellar calcium-binding protein, calflagin. The recombinant molecule showed immunoreactivity with the T. congolense-specific mAb confirming that it is the cognate antigen. Immunofluorescence experiments revealed that Ca2+ modulated the localization of the calflagin molecule in trypanosomes. Structural modelling and comparison with calflagin homologues from other trypanosomatids revealed four non-conserved regions on the surface of the T. congolense molecule that due to differences in surface chemistry and structural topography may form species-specific epitopes. ELISAs using the recombinant calflagin as antigen to detect antibodies in trypanosome-infected cattle showed that the majority of cattle had antibody responses. Area under the Receiver-Operating Characteristic (ROC) curves, associated with host IgG and IgM, were calculated to be 0.623 and 0.709 respectively, indicating a positive correlation between trypanosome infection and the presence of anti-calflagin antibodies. Conclusions While calflagin is conserved among different species of African trypanosomes, our results show that T. congolense calflagin possesses unique epitopes that differentiate this protein from homologues in other trypanosome species. MAb Tc6/42.6.4 has clear utility as a laboratory tool for identifying T. congolense. T. congolense calflagin has potential as a serodiagnostic antigen and should be explored further for its utility in antigen-detection assays for diagnosis of cattle infections. African trypanosomes are parasites that infect humans and domestic animals, causing severe socioeconomic distress in sub-Saharan Africa. Thus developing tools for laboratory- and field-based research for application to epidemiology and disease diagnosis is important if the diseases caused by these parasites are to be controlled. Although Trypanosoma congolense is the most important trypanosome pathogen of cattle in Africa, no species-specific molecules found in infective bloodstream forms (BSF) of the parasites have been identified, thus limiting development of diagnostic tests and epidemiological tools. We have biochemically characterized and modeled the structure of one such molecule, called calflagin, from this parasite and genetically engineered and purified a form of the protein for use in testing cattle for trypanosome infections. In addition, we made new monoclonal antibodies to the calflagin molecule. Our results show that the calflagin and its specific antibodies are useful tools for research in epidemiological and diagnostic applications.

Abstract
1 The circulatory effects of labetalol have been studied in 88 patients undergoing plastic surgery, 8 patients with carcinoma of the breast, 10 with carcinoma in the head and neck, and in 2 patients with phaeochromocytoma, each anaesthetized twice. 2 The use of labetalol intravenously produced hypotension and a bloodless operating field in patients undergoing plastic surgery and in those undergoing radical surgery for the removal of carcinoma. 3 Two patients with phaeochromocytoma pre-treated with oral labetalol before anaesthesia, had well controlled BPs and heart rates during surgery, although in one instance additional intravenous labetalol was required. 4 Pre-operative preparation of patients with phaeochromocytoma with labetalol seems to be simpler and safer than previous techniques involving drugs with separate alpha- and beta-adrenoceptor-blocking effects.

Abstract
The Standard for the Exchange of Nonclinical Data (SEND), adopted by the US FDA, is part of a set of regulations and guidances requiring the submission of standardized electronic study data for nonclinical and clinical data submissions. SEND is the nonclinical implementation of SDTM (Study Data Tabulation Model), the standard electronic format for clinical regulatory submissions to FDA. SEND, SDTM, and the associated Controlled Terminology have been developed by CDISC (Clinical Data Interchange Standards Consortium). In order to successfully implement SEND, interdisciplinary contributions between sponsors and CROs, need a model for task allocation. This is being undertaken by the Pharmaceutical Users Software Exchange (PhUSE). Because SEND is currently the preferred submission format of the US FDA only and will become required by it starting in December 2016, only American academic societies and companies are actively involved. An exception to this is the INHAND initiative, which leads the way in standardizing terminology for toxicological pathology. On the other hand, international globalization of other clinical and nonclinical practices is not feasible because there are substantial differences between the US and non-US countries in CRO involvement in drug development. Thus, non-US countries must consider and develop approaches to SEND that meet their needs. This paper summarizes the activities of the major organizations involved in SEND development and implementation, discusses the effective use of SEND, and details a compliance scheme (research material of the Showa University School of Medicine) illustrating how pharmaceutical companies can complete a large amount of work up to an FDA application with the effective utilization of CROs and solution providers.

Abstract
BACKGROUND AND AIMS The aim of this study was to assess prevalence and associated bother of male lower urinary tract symptoms (LUTS), especially of urgency and other storage symptoms, since these are generally assumed to be underdiagnosed/undertreated in men. METHODS Data on bladder condition of men ≥ 40 years were prospectively collected by 124 general practitioners (GPs) during a regular visit for any reason, using the validated ICIQ-MLUTS questionnaire. For 13 symptoms, prevalence (scale 0-4) and bother (scale 0-10) were scored. General bladder-related quality of life (scale 0-3) was also assessed. RESULTS Data from 5890 men (mean age: 61.2 years) were analysed. A total of 7.7% had urgency most or all of the time (score ≥ 3) and 6.2% had bothersome urgency (score ≥ 3 + bother score ≥ 5). Nocturia (69.2%) and urgency (58.3%) were the most prevalent and bothersome symptoms. Both prevalence and bother of all LUTS increased with age. Additionally, 28.9% of men reported to be a little bothered by their bladder condition in everyday life, while 11.9% were bothered a lot/very much (2.5% in age group 40-49 years increasing to 29.2% in those > 80 years). CONCLUSIONS In the general population of men ≥ 40 years who visited a GP for any reason, 41% indicated to be at least a little bothered by their bladder condition. The prevalence of LUTS, especially nocturia and urgency, is high and a significant number of men indicated to be seriously bothered. Increasing awareness of male LUTS, and storage symptoms in particular, is warranted to discuss management options that could increase quality of life.
