    Abstract Artificial intelligence (AI) applied to medicine offers immense promise, in addition to safety and regulatory concerns. Traditional AI produces a core algorithm result, typically without a measure of statistical confidence or an explanation of its biological-theoretical basis. Efforts are underway to develop explainable AI (XAI) algorithms that not only produce a result but also an explanation to support that result. Here we present a framework for classifying XAI algorithms applied to clinical medicine: An algorithm's clinical scope is defined by whether the core algorithm output leads to observations (eg, tests, imaging, clinical evaluation), interventions (eg, procedures, medications), diagnoses, and prognostication. Explanations are classified by whether they provide empiric statistical information, association with a historical population or populations, or association with an established disease mechanism or mechanisms. XAI implementations can be classified based on whether algorithm training and validation took into account the actions of health care providers in response to the insights and explanations provided or whether training was performed using only the core algorithm output as the end point. Finally, communication modalities used to convey an XAI explanation can be used to classify algorithms and may affect clinical outcomes. This framework can be used when designing, evaluating, and comparing XAI algorithms applied to medicine.

    Abstract Objectives: Preanalytical factors, such as hemolysis, affect many components of a test panel. Machine learning can be used to recognize these patterns, alerting clinicians and laboratories to potentially erroneous results. In particular, machine learning might identify which cases of elevated potassium from a point-of-care (POC) basic metabolic panel are likely erroneous.
    Methods: Plasma potassium concentrations were compared between POC and core laboratory basic metabolic panels to identify falsely elevated POC results. A logistic regression model was created using these labels and the other analytes on the POC panel.
    Results: This model has high predictive power in classifying POC potassium as falsely elevated or not (area under the curve of 0.995 when applied to the test data set). A rule-in and rule-out approach further improves the model's applicability with a positive predictive value of around 90% and a negative predictive value near 100%.
    Conclusions: Machine learning has the potential to detect laboratory errors based on the recognition of patterns in commonly requested multianalyte panels. This could be used to alert providers at the POC that a result is suspicious or used to monitor the quality of POC results.

    Abstract A female presented in the sixth decade of life with a history of undifferentiated small cell carcinoma of the right breast in clinical remission, status-post chemotherapy and resection 6 years previously, presented with a chronic anterior knee skin nodule that grew in size over the prior 5-6 weeks. She had no history of opportunistic infections or recent immunosuppression. As it grew, the nodule became tender to touch. Examination revealed a 4-6 mm superficial purple-red nodule. Also, a similar lesion was present on the dorsum of her left foot for the past year, which also recently grew and became tender. The patient did report frequently kneeling on soil when gardening in Florida. She reported no other symptoms. Due to a concern for cutaneous metastasis of the patient's previously diagnosed small cell carcinoma of the breast, the anterior knee lesion was biopsied. Histology revealed histocyte-rich inflammation with foci of acute inflammation as well as pigmented fungal forms. Subsequent fungal culture of excised tissue grew

    Abstract Salivary blood is known to increase in patients with intraoral mucosal bleeding. Mucosal bleeding is a frequent sequelae of thrombocytopenia, which is typically managed with platelet transfusion. Within the past few years, multiple different types of platelet products have become available, each with potential differences in efficacy. Typically, platelet transfusion efficacy is demonstrated by the increase in platelet count after transfusion. However this approach is complicated by the fact that activated platelets tend to produce lower post-transfusion platelet counts, but may be more efficacious in a bleeding patient. Intraoral blood levels, measured by salivary transferrin, urine dipstick hemoglobin or another method, could be used as an in vivo assay to monitor a patient's response to platelet transfusion and compare different types of platelet products.

    Abstract The effort to collect convalescent plasma from individuals who recovered from COVID-19 began in earnest during the spring of 2020. Either whole blood or apheresis donations were obtained, the latter yielding higher numbers of units per donor per collection and more frequent collections. The NorthShore University HealthSystem blood donor center purchased 2 Alyx (Fresenius Kabi) apheresis plasma collection devices and quickly implemented them in order to collect COVID-19 convalescent plasma. Apheresis-experienced and inexperienced phlebotomists operated the instruments. Donors were collected >14 days from symptom resolution and all donors were negative by SARS-CoV-2 nasopharyngeal swab. Both internal metrics of performance as well as a post donation survey were used to evaluate the feasibility implementing this collection program. During the first 100 days of the collection program, 650 plasma units were collected. In particular, during the first week of the program, 38 units were collected and distributed to hospitals under the emergency investigational new drug and expanded access program. Fifty-one donors (15%) were deferred due to vital signs out of range or donor screening questions. Thirty-one donors (10%) were deferred due to positive nasopharyngeal swab. Lower than target yield occurred in 16.6% of collections due to donor reactions or flow errors. Donors rated the overall program lower, but not the staff, when they reported symptoms related to collection. In conclusion, a hospital-based apheresis convalescent plasma collection program can be rapidly implemented. Donor reaction rates and vein infiltration rates should be carefully monitored for each phlebotomist.
