“That Can't Be!”: Perceptions of HIV and Hepatitis C screening during admission to an acute care surgery service

Background: A large number of patients live with undiagnosed HIV and/or hepatitis C despite broadened national screening guidelines. European studies, however, suggest many patients falsely believe they have been screened during a prior hospitalization. This study aims to define current perceptions among trauma and emergency general surgery (EGS) patients regarding HIV and hepatitis C screening practices. Methods: Prospective survey administered to adult (>18 years old) acute care surgery service (trauma and EGS) patients at a Level 1 academic trauma center. The survey consisted of 13 multiple choice questions: demographics, whether admission tests included HIV and hepatitis C at index and prior hospital visits and whether receiving no result indicated a negative result, prior primary care screening. Response percentages calculated in standard fashion. Results: One hundred and twenty-five patients were surveyed: 80 trauma and 45 EGS patients. Overall, 32% and 29.6% of patients believed they were screened for HIV and hepatitis C at admission. There was no significant difference in beliefs between trauma and EGS. Sixty-eight percent of patients had a hospital visit within 10 years of these, 49.3% and 44.1% believe they had been screened for HIV and hepatitis C. More EGS patients believed they had a prior screen for both conditions. Among patients who believed they had a prior screen and did not receive any results, 75.9% (HIV) and 80.8% (hepatitis C) believed a lack of results meant they were negative. Only 28.9% and 23.6% of patients had ever been offered outpatient HIV and hepatitis C screening. Conclusions: A large portion of patients believe they received admission or prior hospitalization HIV and/or hepatitis C screening and the majority interpreted a lack of results as a negative diagnosis. Due to these factors, routine screening of trauma/EGS patients should be considered to conform to patient expectations and national guidelines, increase diagnosis and referral for medical management, and decrease disease transmission.
