Introduction: Patients are more likely to complete colorectal cancer screening when recommended by a race-concordant healthcare provider. Leveraging virtual healthcare assistants to deliver tailored screening interventions may promote adherence to colorectal cancer screening guidelines among diverse patient populations. The purpose of this pilot study is to determine the efficacy of the Agent Leveraging Empathy for eXams virtual healthcare assistant intervention to increase patient intentions to talk to their doctor about colorectal cancer screening. It also examines the influence of animation and race concordance on intentions to complete colorectal cancer screening.

Methods: White and Black adults (N=1,363) aged 50-73 years and not adherent to colorectal cancer screening guidelines were recruited from Qualtrics Panels in 2018 to participate in a 3-arm (animated virtual healthcare assistant, static virtual healthcare assistant, attention control) message design experiment. In 2020, a probit regression model was used to identify the intervention effects.

Results: Participants assigned to the animated virtual healthcare assistant (p<0.01) reported higher intentions to talk to their doctor about colorectal cancer screening than participants assigned to the other conditions. There was a significant effect of race concordance on colorectal cancer screening intentions but only in the static virtual healthcare assistant condition (p=0.04). Participant race, age, trust in healthcare providers, health literacy, and cancer information overload were also significant predictors of colorectal cancer screening intentions.

Conclusions: Animated virtual healthcare assistants were efficacious compared with the static virtual healthcare assistant and attention control conditions. The influence of race concordance between source and participant was inconsistent across conditions. This warrants additional investigation in future studies given the potential for virtual healthcare assistant‒assisted interventions to promote colorectal cancer screening within guidelines.

Case Report of Intractable Vomiting and Abdominal Pain Related to Heavy Daily Cannabis Use.

S D Med 2016 Spec;No:60-63

Department of Psychiatry, University of South Dakota Sanford School of Medicine.

Case: A highly anxious and dehydrated adolescent came to a local emergency department with complaints of intractable emesis, weight loss, and abdominal pain. He stated that bathing and "guzzling water" ameliorated symptoms. He admitted to using marijuana socially. Efforts at palliation with benzodiazepines, atypical antipsychotics, and antiemetic medications were unable to soothe the patient. After thorough initial diagnostics and physical exam failed to elucidate etiology, the patient was referred to an inpatient psychiatric facility for further evaluation of potential psychosomatic or affective causes. During psychiatric evaluation and upon obtaining additional information from family and reviewing the work done by primary care providers, the patient was questioned stringently about his marijuana use patterns. Questioning revealed that the patient had previous chemical dependency treatment, legal charges related to drug use, and heavy daily marijuana use including "dabbing," ingestion of THC candy, and smoking up to several grams a day.

Discussion: Cannabinoid hyperemesis syndrome (CHS) consists of intractable emesis, abdominal pain, and weight loss. There is often a history of symptom amelioration with bathing and showering. These patients may or may not admit to heavy marijuana use. Cannabis effects vary and are dose dependent. Historically, CHS would require over a year of heavy daily use. In this day and age of higher THC potency marijuana and even higher THC potency "dabs," it is anticipated that more cases of cannabis related syndromes in general, and CHS in particular will be presenting more frequently to ambulatory and emergency room settings. The patients will potentially be younger and have a shorter duration of heavy cannabis use before symptoms start. A high index of suspicion will be required to prevent expensive and potentially invasive workups and thus delaying diagnosis and treatment.
