Purpose: To construct a urologic cancer database using a standardized, reproducible method, and to assess preliminary characteristics of this cohort.Materials and Methods: Patients with prostate, bladder, and kidney cancers who were enrolled with diagnostic codes in the electronic medical record (EMR) at Asan Medical Center from 2007–2016 were included. Research Electronic Data Capture (REDCap) was used to design the Asan Medical Center-Urologic Cancer Database (AMC-UCD). The process included developing a data dictionary, applying branching logic, mapping clinical data warehouse structures, alpha testing, clinical record summary testing, creating “standards of procedure,” importing data, and entering data. Descriptive statistics were used to identify rates of surgeries and numbers of patients.Results: Clinical variables (n=407) were selected to develop a data dictionary from REDCap. In total, 20,198 urologic cancer patients visited our institution from 2007–2016 (bladder cancer, 4,616; kidney cancer, 5,750; prostate cancer, 10,330). The overall numbers of patients and surgeries increased over time, with robotic surgeries rapidly growing over a decade. The most common treatment for urologic cancer was surgery, followed by chemotherapy and radiation therapy.Conclusions: Using a standardized method, the AMC-UCD fosters multidisciplinary research. This constructed database provides access to clinical statistics to effectively assist research. Preliminary data should be refined through EMR chart review. The successful organization of data from 2007–2016 provides a framework for future periods of investigation and prospective models.

Test Ordering

Abstract Introduction/Objective In teaching hospitals, patients receive direct care from a succession of different physicians, each of whom may order diagnostic tests on the same patient resulting in multiple physicians unknowingly ordering the same test in the same time period, leading to overutilization. We examined the association of test-ordering by multiple physicians with duplication of two tests, Beta D-Glucan (BDG) and CMV Viral Load by PCR non blood, as aid for detection of fungal and cytomegaloviral infections, respectively Methods Retrospective medical records at Baylor University Medical Center, Dallas were examined in between 10/1/2019- 10/30/2019. A total 167 test orders were identified for CMV Viral Load non blood and BDG presence in blood. Each medical record was assessed for frequency of ordering along with the physicians who ordered them Results A total 167 tests were ordered in which, 120 times BDG was ordered and 52 times CMV was ordered. Singleton orders were noted in 85(50%) instances of BDG & 30(17%) for CMV.Multiple test orders were 44 (25%) for BDG and 8 (4%) for CMV respectively. Both CMV and BDG were ordered together 57 times. The time stamps of multiple test orders in individual patients was assessed for instances of orders that were less than 3 days apart and analysis showed out of the 44 multiple test orders, 34% (15) test orders were ordered less than 3 days apart and 66%(29) tests were ordered more than 3 days apart for BDG. Upon chart review, most of these quickly successive orders were by different physicians. The estimated costs of the duplicate orders are 4334.0$ & 1104.16$ for BDG and CMV respectively. Conclusion CMV and BDG are commonly ordered on many patients. Analysis shows that many times, physicians order testing when the same test has been ordered very recently by a separate physician. Note that for both tests, retesting in less than three days is not normally indicated, however this happens often, especially for BDG. This is most likely due to difficulty in determining within the EHR what tests are drawn and “pending’ but not yet finalized and reported. With usage of prompts/ alerts in EMR that warn of existing “pending’ orders by another caregiver, the frequency of duplicate test ordering for the same patient may be reduced, in turn reducing the costs of healthcare.

The effect of perioperative sarcopenic changes on prognosis remains unclear. We conducted a retrospective cohort study with 2333 non-metastatic colorectal cancer patients treated between January 2009 and December 2012 at the Asan Medical Center. The body composition at diagnosis was measured via abdominopelvic computed tomography (CT) using Asan-J software. Patients underwent CT scans preoperatively, as well as at 6 months–1 year and 2–3 years postoperatively. The primary outcome was the association between perioperative sarcopenic changes and survival. According to sarcopenic criteria, 1155 (49.5%), 890 (38.2%), and 893 (38.3%) patients had sarcopenia preoperatively, 6 months–1 year, and 2–3 years postoperatively, respectively. The 5-year overall survival (OS) (95.8% vs. 92.1%, hazard ratio (HR) = 2.234, p < 0.001) and 5-year recurrence-free survival (RFS) (93.2% vs. 86.2%, HR = 2.251, p < 0.001) rates were significantly lower in patients with preoperative sarcopenia. Both OS and RFS were lower in patients with persistent sarcopenia 2–3 years postoperatively than in those who recovered (OS: 96.2% vs. 90.2%, p = 0.001; RFS: 91.1% vs. 83.9%, p = 0.002). In multivariate analysis, postoperative sarcopenia was confirmed as an independent factor associated with decreased OS and RFS. Pre- and postoperative sarcopenia and changes in the condition during surveillance were associated with oncological outcomes.

Objective The need for a biomarker with robust sensitivity and specificity in diagnosing systemic lupus erythematosus (SLE) remains unmet. Compared with blood samples, urine samples are more easily collected; thus, we aimed to identify such a biomarker based on urinary proteomics which could distinguish patients with SLE from healthy controls (HCs). Methods Urine samples were collected from 76 SLE patients who visited rheumatology clinic in 2019 at Asan medical center and from 25 HCs. Urine proteins were analyzed using sequential windowed acquisition of all theoretical fragment ion spectra-mass spectrometry, and the candidate marker was confirmed by enzyme-linked immunosorbent assay (ELISA). Receiver operating characteristic curve analysis was used to determine the diagnostic value of the candidate biomarker. Results Of 1157 proteins quantified, 153 were differentially expressed in urine samples from HCs. Among them were previously known markers including α-1-acid glycoprotein 1, α-2-HS-glycoprotein, ceruloplasmin, and prostaglandin-H2 D-isomerase. Moreover, the amount of β-2 glycoprotein (APOH) was increased in the urine of patients with SLE. The ELISA results also showed the level of urine APOH was higher in patients with SLE than in HCs and patients with rheumatoid arthritis. Moreover, the level was not different between SLE patients with and without nephritis. The urine APOH had an area under the curve value of 0.946 at a cut-off value of 228.53 ng/mg (sensitivity 91.5%, specificity 92.0%) for the diagnosis of SLE. Conclusion The results indicate that the urine APOH level can be an appropriate screening tool in a clinical setting when SLE is suspected.

Routine Histopathologic Examination

Objectives During septoplasty, normal cartilage and bone are often sent for pathologic examination despite benign appearance. We explored pathology results following septoplasty from April 2016 to April 2018, examining clinical value and relevance, implications, and cost analysis. Study Design Retrospective chart review. Setting Single-institution academic medical center. Methods A retrospective chart review was compiled by using Current Procedural Terminology code 30520 for septoplasty for indication of nasal obstruction, deviated septum, and nasal deformity. Results A total of 236 consecutive cases were identified spanning a 2-year period. Septoplasty specimens were sent for pathology evaluation in 76 (31%). The decision to send a specimen for histopathology was largely physician dependent. No cases yielded unexpected or significant pathology that changed management. The average total charges for septoplasty were $10,200 at our institution, with 2.2% of procedural charges accounting for pathology preparation and review, averaging $225. Nationally, this results in an estimated charged cost of $58.5 million. The Centers for Medicare and Medicaid Services (CMS) reimbursement for septoplasty pathology charges was $46 in 2018, accounting for 1.3% of hospital-based reimbursements and 2.2% of ambulatory center reimbursements. With CMS as a national model for reimbursement, $11.8 million is spent yearly for septoplasty histopathology. Given that CMS reimbursement is significantly lower than private insurers, national total reimbursement is likely considerably higher. Conclusion Routine pathology review of routine septoplasty specimens is unnecessary, unremarkable, and wasteful. Correlation of the patient’s presentation and intraoperative findings should justify the need for pathology evaluation. This value-based approach can offer significant direct and indirect cost savings. Level of evidence 4.

The Impact

Background: Antibiotic resistance has increased at alarming rates, driven predominantly by antibiotic overuse. Although most antibiotic use occurs in outpatients, antimicrobial stewardship programs have primarily focused on inpatient settings. A major challenge for outpatient stewardship is the lack of accurate and accessible electronic data to target interventions. We sought to develop and validate an electronic algorithm to identify inappropriate antibiotic use for outpatients with acute bronchitis. Methods: This study was conducted within the University of Pennsylvania Health System (UPHS). We used ICD-10 diagnostic codes to identify encounters for acute bronchitis at any outpatient UPHS practice between March 15, 2017, and March 14, 2018. Exclusion criteria included underlying immunocompromising condition, other comorbidity influencing the need for antibiotics (eg, emphysema), or ICD-10 code at the same visit for a concurrent infection (eg, sinusitis). We randomly selected 300 (150 from academic practices and 150 from nonacademic practices) eligible subjects for detailed chart abstraction that assessed patient demographics and practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for assessment of the electronic algorithm. Because antibiotic use is not indicated for this study population, appropriateness was assessed based upon whether an antibiotic was prescribed or not. Results: Of 300 subjects, median age was 61 years (interquartile range, 50–68), 62% were women, 74% were seen in internal medicine (vs family medicine) practices, and 75% were seen by a physician (vs an advanced practice provider). On chart review, 167 (56%) subjects received an antibiotic. Of these subjects, 1 had documented concern for pertussis and 4 had excluding conditions for which there were no ICD-10 codes. One received an antibiotic prescription for a planned dental procedure. Thus, based on chart review, 161 (54%) subjects received antibiotics inappropriately. Using the electronic algorithm based on diagnostic codes, underlying and concurrent conditions, and prescribing data, the number of subjects with inappropriate prescribing was 170 (56%) because 3 subjects had antibiotic prescribing not noted based on chart review. The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were the following: sensitivity, 100% (161 of 161); specificity, 94% (130 of 139); positive predictive value, 95% (161 of 170); and negative predictive value, 100% (130 of 130). Conclusions: For outpatients with acute bronchitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. This algorithm could be used to efficiently assess prescribing among practices and individual clinicians. The impact of interventions based on this algorithm should be tested in future studies.Funding: NoneDisclosures: None

Objectives:To evaluate the outcomes of pregnancy in young women (<40 years old) with early endometrial cancer or atypical complex hyperplasia who were treated by conservative management followed by assisted reproductive technology (ART).Materials and Methods:Medical charts of 11 patients treated from January 1997 to October 2007 at Asan Medical Center were retrospectively reviewed. These patients had all been treated with progestin and serial dilatation and curettage as primary fertility-preserving therapies.Results:After pathological remission of disease, 10 patients tried to become pregnant by ART, 4 by in vitro fertilization and embryo transfer, and 6 by controlled ovarian hyperstimulation, with or without intrauterine insemination. Eight women had intrauterine pregnancies, and 6 patients had live births. Patients have been followed up for 9 to 51 months (mean, 21 months) after delivery, with no evidence of tumor recurrence.Conclusions:Fertility-preserving therapy followed by ART can be a good option in well-selected patients with early endometrial cancer who want to become pregnant.

ABSTRACTObjectiveWe aimed to establish a comprehensive digital phenotype for postpartum hemorrhage (PPH). Current guidelines rely primarily on estimates of blood loss, which can be inaccurate and biased, and ignore a suite of complementary information readily available in electronic medical records (EMR). Inaccurate and incomplete phenotyping contribute to ongoing challenges to track PPH outcomes, develop more accurate risk assessments, and identify novel interventions.MethodsWe constructed a cohort of 71,944 deliveries from the Mount Sinai Health System, 2011-2019. Estimates of postpartum blood loss, shifts in hematocrit intra- and postpartum, administration of uterotonics, surgical treatments, and associated diagnostic codes were combined to identify PPH retrospectively. All clinical features were extracted from structured EMR data and mapped to common data models for maximum interoperability across hospitals. Blinded chart review was done on a randomly selected subset of cases and controls for validation and performance was compared to alternate PPH phenotypes.ResultsWe identified 6,639 cases (9% prevalence) using our phenotype – more than three times as many as using blood loss alone (N=1,747), supporting the need to incorporate other diagnostic and treatment data. Blinded chart review revealed our phenotype had 96% sensitivity, 89% precision, 77% specificity, and 89% accuracy to detect PPH. Alternate phenotypes were less accurate, including a common blood loss-based definition (67%) and a previously published digital phenotype (74%).ConclusionWe have developed a scalable, accurate, and valid digital phenotype that may be of significant use for tracking outcomes and ongoing clinical research to deliver better preventative interventions for PPH.

Objective Limited data exist on non-suicidal self-injury (NSSI) and suicide attempts among psychiatric patients in Korea. In this study, we investigated the clinical characteristics of patients who engaged in NSSI and/or suicide attempts.Methods We performed a retrospective medical chart review of patients with NSSI and/or suicide attempts at the psychiatric department of a university medical center in Seoul between 2017 and 2019. According to their history, patients were allocated to one of three groups: NSSI only, suicide attempts only and NSSI and suicide attempts group. Groups were compared based on sociodemographic characteristics and psychological assessments.Results Overall, 80 patients with NSSI and/or suicide attempts were evaluated. Patients with NSSI and suicide attempts were more likely to be female than the other two groups. Patients with NSSI and suicide attempts were more likely to suffer from Cluster B personality disorder than the other groups. And patients with NSSI and suicide attempts scored significantly higher on novelty-seeking in TCI and RC8, RC9 in MMPI-2.Conclusion Patients with NSSI and/or suicide attempts were more likely to be female, younger, and showed higher levels of psychological disturbances. These findings highlight the importance of early detection and intervention for patients with NSSI.
