11001 Biomedical Informatics Strategies to Enhance Individualized Predictive Models

Sunday, July 24, 2022 | 5 – 6:30 p.m.
1 credit; CME: 1 credit
Precision medicine is based on the development of individualized estimates for patients. There is an increasing use of artificial intelligence (AI) in clinical prediction models (e.g., severity scores, sepsis prediction). Although adoption is still sparse among clinicians, we may soon have a long list of predictive models for a given problem and may have a difficult time deciding which one is best. In this plenary session, Dr. Ohno-Machado will introduce how AI models are developed, tested, and validated. Dr. Ohno-Machado will then discuss performance measures that may help clinicians select these models for routine use. This will be presented in a tutorial format that reviews the main differences between statistical models (e.g., regression) and AI models (e.g., neural networks), and describes how different evaluation measures including model simplicity, explainability, and classification performance can be assessed and compared. The goal is to demystify AI for clinicians and biomedical researchers.

32101 Bad, Better, Best: Putting Machine Learning Models to the Test (President's Invited Session)

Monday, July 25, 2022 | 10:30 a.m. – 12 p.m.
ACCENT: 1.5 credits; CME: 1.5 credits
One of the most exciting new frontiers in laboratory medicine is the application of data analytics techniques to laboratory data. Machine Learning has emerged as a valuable tool for the achieving better diagnostic information from existing laboratory medicine data, thus improving the lab's ability to add interpretive value to the information that is delivered to rest of the health care system. Although this area has generated much excitement, it is important for laboratories to understand common pitfalls in applying machine learning to laboratory data. This interactive session will cover common pitfalls and associated best practices in the development, validation, and reporting of machine learning applications using a case-based, compare/contrast approach with audience polling.

32442 Cannabis and Driving: Biomarkers, Performance, and Officer Observations

Monday, July 25, 2022 | 12:30 – 2 p.m.
ACCENT: 1.5 credits; CME: Not eligible
This session is intended for toxicologists and others who are interested in the effects of cannabis on driving performance. Identifying drivers who have recently used cannabis or cannabis products is challenging because of the variability in dosing materials, routes of administration and pharmacokinetics. Oral fluid, breath, and blood specimens are the primary biological materials being studied to help identify recent use of cannabis products. In this session we will present an update on biomarkers of cannabis use and describe strengths and weaknesses of approaches that use bio-fluids to support identification of driving under the influence. We will also describe results of the largest placebo controlled randomized trial conducted to date that evaluated the effect of cannabis on simulated driving performance. Predictive values of approaches using "cutoff" concentrations of cannabinoids in various biological fluids along with police officer observations will be described.

32446 Population Genomics Health and Precision Medicine (Chair's Invited Session)

Monday, July 25, 2022 | 12:30 – 2 p.m.
ACCENT: 1.5 credits; CME: 1.5 credits
Population-based genomic screening has the predicted ability to reduce morbidity and mortality associated with medically actionable conditions, for example in individuals with cardiovascular and cancer predispositions. There are now several emerging efforts demonstrating the application of genomics for medical care, in both healthy and disease cohorts, and at both institutional and national levels, including the All of Us Research Program as well as the BioMe genomic screening program. However, research is still needed to develop standards for genomic screening, particularly in non-European ancestry populations who are vastly underrepresented in genomic medicine research. This session will focus on advances in precision health large-scale research programs, genomic medicine and the application of precision medicine, with a focus on efforts to better serve underrepresented populations and ameliorate health inequities.

32229 Updates on Chronic Kidney Disease Diagnosis: New Race Neutral eGFR, Measured GFR, and Urine Albumin-to-Creatinine Ratio

Monday, July 25, 2022 | 2:30 – 4 p.m.
ACCENT: 1.5 credits; CME: 1.5 credits
Kidney Disease Initiative Global Outcome 2012 guidelines established a diagnostic classification of CKD using two laboratory parameters: estimated glomerular filtration rate (eGFR) from serum creatinine (sCRE) and urinary albumin-to-creatinine ratio (ACR) [or protein:creatinine ratio (PCR)]. Recently, the National Kidney Foundation (NKF) and the American Society of Nephrology (ASN) joint taskforce recommended the use of CKD-EPI creatinine eGFR equation refit without the race variable, as well as increased use of serum cystatin C for kidney health estimation. However, the directly measured GFR (mGFR) through iohexol has become a standard procedure in some kidney centers. How do eGFR and mGFR compare? How reliable and standardized are serum creatinine, albuminuria, and proteinuria methods? Is the recommended race-neutral eGFR equation the best one for all patients? What are the pitfalls in ACR or PCR measurements? This session, developed with the IFCC Committee on Kidney Diseases will address these critical issues in kidney health.

32230 Valid Vital LDTs: Current State of Regulation Legislation of Laboratory-Developed Tests

Monday, July 25, 2022 | 2:30 – 4 p.m.
ACCENT: 1.5 credits; CME: Not eligible
Changes in the regulation of laboratory-developed tests (LDTs) in the United States (US) has been the subject of debate, proposals, guidance, legislation, and discussion for decades. Multiple legislative bills have been recently introduced into the US congress and viable routes for passage currently exist. These legislative bills propose changes in the regulatory landscape of LDTs that will impact patients, laboratories, and physicians, and have the potential to dramatically alter the practice of medicine in the US. Join experts from leading professional organizations as they discuss key elements of the current legislative proposals, the state of the bills, and address questions posed by the audience. The panel members recently participated in a joint AACC/ACMG/AMP/APC webinar discussing this topic and a robust number of questions across the breadth of legislation and impacts on LDTs. The panel looks forward to an interactive discussion addressing key elements of the legislation and audience questions.

33102 Addressing Preanalytical Issues for Blood Collection and Testing Outside Conventional Locations

Tuesday, July 26, 2022 | 10:30 a.m. – 12 p.m.
ACCENT: 1.5 credits; CME: 1.5 credits
Despite substantial efforts, preanalytical variables continue to be the leading cause of errors for the clinical laboratory. If blood collection by non-phlebotomists or skilled nurses and testing by non-clinical laboratorians is to be moved to non-conventional locations, e.g., at home, pharmacies, or remote other locations, preanalytical errors will increase leading to need for recollection and medical errors. The clinical laboratory may be held responsible for ensuring the quality of distributed testing. Through lectures and an extended panel discussion, we discuss important issues such as improvements in capillary blood collection via fingerstick, the mechanism, detection and preventative measures for sample hemolysis, and the potential value of collecting and testing dried blood spots.

34111 Testing Strategies for Detecting Pediatric Drug Exposure: A Case Based Discussion

Wednesday, July 27, 2022 | 10:30 a.m. – 12 p.m.
ACCENT: 1.5 credits; CME: 1.5 credits
The young victims of changing drug use trends spurred on by the opioid epidemic and COVID-19 pandemic are often overlooked. The opioid epidemic has led to an alarming increase in unintentional pediatric drug exposure. The co-occurring COVID-19 pandemic has led to an increase in prescription drug misuse among early adolescents. These trends call for thoughtful reconsideration of laboratory-based testing strategies for detecting drug exposure in pediatric patients. Discussion of critical questions, such as what immunoassays should be included in urine toxicology panels, what are the consequences of inaccurate screening results, should pediatric testing only be done by definitive mass spectrometry-based methods, is essential. This session will highlight these topics through the perspectives of two different clinical laboratory's unique approaches to pediatric drug testing. Clinical cases will be used to highlight the advantages and disadvantages of different approaches.

Wednesday, July 27, 2022 | 2:30 – 5 p.m.
ACCENT: 2.5 credits; CME: 2.5 credits
Inappropriate lab test utilization includes overutilization, misutilization, and underutilization. It adversely affects patient care and is a financial burden to both the patient and the healthcare system. To address this serious issue, AACC Academy and Science and Practice Core Committee have formed a joint Task Force to develop AACC's Guide to Lab Test Utilization. The Task Force has developed and published 20 guidance documents with more to come. These guidance documents are important resources that outline appropriate test utilization and are targeted to clinical laboratorians, clinicians, and other medical professionals that conduct or order clinical tests. This session will outline the needs assessment for these guidance documents and how they were developed. The speakers will present the published documents in an interactive manner and discuss how individuals can use them within their own practice. The interactive educational format employed within the session will engage the audience using audience poll questions.

35103 Gut Check: Lab Evaluation of Celiac Disease, Inflammatory Bowel Disease, and Irritable Bowel Syndrome

Thursday, July 28, 2022 | 10:30 a.m. – 12 p.m.
ACCENT: 1.5 credits; CME: Not eligible
Annually, millions of patients seek medical advice due to chronic gastrointestinal issues. One challenge for gastroenterologists is differentiating between highly prevalent functional disorders, such as irritable bowel syndrome (IBS), and immune-mediated conditions such as Celiac disease or inflammatory bowel disease (IBD), which require more aggressive treatment. Advancements in noninvasive serology-based diagnostic tests and fecal screening tests have reduced the need for invasive procedures. These developments simultaneously have created challenges with test-utilization due to varying diagnostic accuracies and lack of guidance. To help mitigate inappropriate testing and optimize patient outcomes, laboratory stewardship and implementation of proper clinical decision support tools are critical. During this session, current updates on analytical and clinical recommendations, developments in testing methodologies and strategies, including reflex algorithms, and gaps in the laboratory diagnosis of patients with celiac disease and IBD will be presented using illustrative cases and data.

Thursday, July 28, 2022 | 10:30 a.m. – 12 p.m.
ACCENT: 1.5 credits; CME: 1.5 credits
This session will present social challenges for the clinical management of patient populations, including transgender, intersex, and non-binary individuals, whose genders are inconsistent with laboratory reports. Such challenges present obstacles related to molecular diagnostics. Furthermore, unique issues inherent to the transgender community will be defined in complex social situations, psychological burdens, and self/gender-identifying terminology that may limit medical care. This session will explain molecular mechanisms resulting in syndromic conditions, chromosomal alterations, and other molecular changes that can lead to ambiguous genitalia and/or alternate gender assignments. Clinical presentations will be discussed in specific molecular genetic alterations. The last portion of this session will address molecular diagnostic challenges in transgender and related populations that can result in lab errors, delays in pathology reports, missed diagnosis, and potentially translate into patient harm. Molecular laboratory medicine can be strengthened through understanding and implementing practice-based changes related to these medical challenges in transgender populations.
