Can computer-based feedback improve emergency department patient uptake of rapid HIV screening?

ABSTRACT: We determine whether (1) an audiocomputer-delivered tailored feedback intervention increases emergency department (ED) patient uptake of opt-in, nontargeted rapid HIV screening; and (2) uptake is greater among patients who report more HIV risk and among those whose self-perceived HIV risk increases from baseline after completion of an HIV risk assessment.ED patients aged 18 to 64 years were randomly assigned to receive either an assessment about reported and self-perceived HIV risk or an identical assessment plus feedback about their risk for having or acquiring an HIV infection, tailored according to their reported risk. All participants were offered a fingerstick rapid HIV test. Two-sample tests of binomial proportions were used to compare screening uptake by study arm. Multivariable logistic regression was used to assess the relationship of reported HIV risk and an increase in self-perceived HIV risk with uptake of HIV screening.Of the 566 participants, the median age was 29 years, 62.2% were women, and 66.9% previously had been tested for HIV. Uptake of HIV screening was similar in the intervention and no intervention arms (54.1% versus 55.5% [?=-0.01%; 95% confidence interval {CI} -0.09% to 0.07%]). An increase in self-perceived HIV risk predicted greater uptake of HIV screening for women (odds ratio 2.15; 95% CI 1.08 to 4.28) but not men (odds ratio 1.61; 95% CI 0.60 to 4.30). Uptake of HIV screening was not related to reported HIV risk.Uptake of rapid HIV screening in the ED was not improved by this feedback intervention. Other methods need to be investigated to improve uptake of HIV screening by ED patients.

Project description:BackgroundEmergency department (ED) patients comprise a high-risk population for alcohol misuse and sexual risk for HIV. In order to design future interventions to increase HIV screening uptake, we examined the interrelationship among alcohol misuse, sexual risk for HIV and HIV screening uptake among these patients.MethodsA random sample of 18-64-year-old English- or Spanish-speaking patients at two EDs during July-August 2009 completed a self-administered questionnaire about their alcohol use using the Alcohol Use Questionnaire, the Alcohol Use Disorders Identification Test (AUDIT), and the HIV Sexual Risk Questionnaire. Study participants were offered a rapid HIV test after completing the questionnaires. Binging (? five drinks/occasion for men, ? four drinks for women) was assessed and sex-specific alcohol misuse severity levels (low-risk, harmful, hazardous, dependence) were calculated using AUDIT scores. Analyses were limited to participants who had sexual intercourse in the past 12 months. Multivariable logistic regression was used to assess the associations between HIV screening uptake and (1) alcohol misuse, (2) sexual risk for HIV, and (3) the intersection of HIV sexual risk and alcohol misuse. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were estimated. All models were adjusted for patient demographic characteristics and separate models for men and women were constructed.ResultsOf 524 participants (55.0% female), 58.4% identified as white, non-Hispanic, and 72% reported previous HIV testing. Approximately 75% of participants reported drinking alcohol within the past 30 days and 74.5% of men and 59.6% of women reported binge drinking. A relationship was found between reported sexual risk for HIV and alcohol use among men (AOR 3.31 [CI 1.51-7.24]) and women (AOR 2.78 [CI 1.48-5.23]). Women who reported binge drinking were more likely to have higher reported sexual risk for HIV (AOR 2.55 [CI 1.40-4.64]) compared to women who do not report binge drinking. HIV screening uptake was not higher among those with greater alcohol misuse and sexual risk among men or women.ConclusionsThe apparent disconnection between HIV screening uptake and alcohol misuse and sexual risk for HIV among ED patients in this study is concerning. Brief interventions emphasizing these associations should be evaluated to reduce alcohol misuse and sexual risk and increase the uptake of ED HIV screening.

Project description:ObjectivesPrior research has demonstrated that emergency department (ED) patient acceptance of human immunodeficiency virus (HIV) screening is partially dependent on patients' self-perceived risk of infection. The primary objective of this study was to determine the effectiveness of audio computer-assisted self-interview (ACASI)-based feedback. The intervention aimed to increase patient's self-perceived risk of being HIV infected by providing immediate feedback on their risk behaviors.MethodsThis 1-year, randomized, controlled trial at a U.S. ED enrolled a random sample of 18- to 64-year-old subcritically ill or injured adult patients who were not known to be HIV infected. All participants completed an anonymous, ACASI-based questionnaire about their HIV risk behaviors related to injection drug use and sex, as well as their self-perceived risk for being HIV infected. Participants were randomly assigned to one of two study groups: an intervention group in which participants received immediate ACASI-based feedback in response to each of their reported risk behaviors or a no-intervention group without feedback. Participants were asked to indicate their level of HIV risk on a five-point scale before and after they answered the questions. Change in level of self-perceived HIV risk was calculated and compared by study group using Pearson's chi-square test. An HIV risk behavior score that summarized reported HIV risk behavior was devised. Because HIV risk behaviors differ by sex, scores were calculated separately for each sex. Linear regression models that adjusted for study group and same subject covariance were employed to determine if higher HIV risk behavior scores were associated with an increase in self-perceived HIV risk.ResultsOf the 566 trial participants, the median age was 29 years (interquartile range [IQR] = 22-43 years), 62.2% were females, and 66.9% had been tested previously for HIV. After answering the reported HIV risk behavior questions, 12.6% of participants had an increase, 79.9% had no change, and 7.5% had a decrease in self-perceived HIV risk. Of the 46.6% of participants who initially indicated that they were not at risk for HIV, 11.4% had an increase in self-perceived HIV risk after answering the reported HIV risk behavior questions. Change in self-perceived HIV risk did not differ by study group (p = 0.77). There were no differences in reported HIV risk scores between the intervention and no-intervention groups for females (p = 0.78) or males (p = 0.86). In the linear regression models, a greater increase in self-perceived HIV risk was associated with higher reported HIV risk behavior scores for females (beta = 0.59, 95% confidence interval [CI] = 0.15, 1.04) but not for males (beta = 1.00, 95% CI = -0.13 to 2.14).ConclusionsSome ED patients can be moved, although modestly, to recognize their risk for being HIV infected by asking about their HIV risk behaviors. However, ACASI-based feedback messages about HIV risk behaviors do not increase subjects' self-perceived HIV risk. Female ED patients appear to increase their self-perceived HIV risk more than males when queried about their HIV risk behaviors.
