Informed consent for opt-in HIV testing via tablet kiosk: an assessment of patient comprehension and acceptability

Patient Perspectives and Preferences for Consent in the Digital Health Context: State-of-the-art Literature Review

BACKGROUND

The increasing integration of digital health tools into care may result in a greater flow of personal health information (PHI) between patients and providers. Although privacy legislation governs how entities may collect, use, or share PHI, such legislation has not kept pace with digital health innovations, resulting in a lack of guidance on implementing meaningful consent. Understanding patient perspectives when implementing meaningful consent is critical to ensure that it meets their needs. Consent for research in the context of digital health is limited.

OBJECTIVE

This state-of-the-art review aimed to understand the current state of research as it relates to patient perspectives on digital health consent. Its objectives were to explore what is known about the patient perspective and experience with digital health consent and provide recommendations on designing and implementing digital health consent based on the findings.

METHODS

A structured literature search was developed and deployed in 4 electronic databases-MEDLINE, IEEE Xplore, Scopus, and Web of Science-for articles published after January 2010. The initial literature search was conducted in March 2021 and updated in March 2022. Articles were eligible for inclusion if they discussed electronic consent or consent, focused on the patient perspective or preference, and were related to digital health or digital PHI. Data were extracted using an extraction template and analyzed using qualitative content analysis.

RESULTS

In total, 75 articles were included for analysis. Most studies were published within the last 5 years (58/75, 77%) and conducted in a clinical care context (33/75, 44%) and in the United States (48/75, 64%). Most studies aimed to understand participants' willingness to share PHI (25/75, 33%) and participants' perceived usability and comprehension of an electronic consent notice (25/75, 33%). More than half (40/75, 53%) of the studies did not describe the type of consent model used. The broad open consent model was the most explored (11/75, 15%). Of the 75 studies, 68 (91%) found that participants were willing to provide consent; however, their consent behaviors and preferences were context-dependent. Common patient consent requirements included clear and digestible information detailing who can access PHI, for what purpose their PHI will be used, and how privacy will be ensured.

CONCLUSIONS

There is growing interest in understanding the patient perspective on digital health consent in the context of providing clinical care. There is evidence suggesting that many patients are willing to consent for various purposes, especially when there is greater transparency on how the PHI is used and oversight mechanisms are in place. Providing this transparency is critical for fostering trust in digital health tools and the innovative uses of data to optimize health and system outcomes.

Recruitment of US Adolescents and Young Adults (AYA) into Human Immunodeficiency Virus (HIV)-Related Behavioral Research Studies: A Scoping Review

Purpose of Review

The objective of this scoping review was to examine the range of published evidence on recruitment approaches and outcomes of US adolescents and young adults (AYA) ages (18–29 years) into human immunodeficiency virus (HIV)–related behavioral research studies during the past 10 years.

Recent Findings

Implementation of effective behavioral research strategies among HIV at-risk and infected AYA is key to ending the HIV epidemic and necessitates successful recruitment strategies.

Summary

A comprehensive search was executed across four electronic databases. Of the 1697 identified studies, seven met inclusion criteria with six of these seven directed to HIV prevention. Most studies used online recruitment as part of a hybrid strategy, and combined field-based/in-person and online methods. Recruitment strategies and outcomes, resources and compensation, procedures for consent, and timelines varied among all seven studies. Our results highlight the need for development of recruitment models in alignment with behavioral strategies aimed to treat and prevent HIV among US AYA.

The Role of Health Kiosks: A Scoping Review (Preprint)

Background

Health kiosks are publicly accessible computing devices that provide access to services, including health information provision, clinical measurement collection, patient self–check-in, telemonitoring, and teleconsultation. Although the increase in internet access and ownership of smart personal devices could make kiosks redundant, recent reports have predicted that the market will continue to grow.

Objective

We seek to clarify the current and future roles of health kiosks by investigating the settings, roles, and clinical domains in which kiosks are used; whether usability evaluations of health kiosks are being reported, and if so, what methods are being used; and what the barriers and facilitators are for the deployment of kiosks.

Methods

We conducted a scoping review using a bibliographic search of Google Scholar, PubMed, and Web of Science databases for studies and other publications between January 2009 and June 2020. Eligible papers described the implementation as primary studies, systematic reviews, or news and feature articles. Additional reports were obtained by manual searching and querying the key informants. For each article, we abstracted settings, purposes, health domains, whether the kiosk was opportunistic or integrated with a clinical pathway, and whether the kiosk included usability testing. We then summarized the data in frequency tables.

Results

A total of 141 articles were included, of which 134 (95%) were primary studies, and 7 (5%) were reviews. Approximately 47% (63/134) of the primary studies described kiosks in secondary care settings. Other settings included community (32/134, 23.9%), primary care (24/134, 17.9%), and pharmacies (8/134, 6%). The most common roles of the health kiosks were providing health information (47/134, 35.1%), taking clinical measurements (28/134, 20.9%), screening (17/134, 12.7%), telehealth (11/134, 8.2%), and patient registration (8/134, 6.0%). The 5 most frequent health domains were multiple conditions (33/134, 24.6%), HIV (10/134, 7.5%), hypertension (10/134, 7.5%), pediatric injuries (7/134, 5.2%), health and well-being (6/134, 4.5%), and drug monitoring (6/134, 4.5%). Kiosks were integrated into the clinical pathway in 70.1% (94/134) of studies, opportunistic kiosks accounted for 23.9% (32/134) of studies, and in 6% (8/134) of studies, kiosks were used in both. Usability evaluations of kiosks were reported in 20.1% (27/134) of papers. Barriers (e.g., use of expensive proprietary software) and enablers (e.g., handling of on-demand consultations) of deploying health kiosks were identified.

Conclusions

Health kiosks still play a vital role in the health care system, including collecting clinical measurements and providing access to web-based health services and information to those with little or no digital literacy skills and others without personal internet access. We identified research gaps, such as training needs for teleconsultations and scant reporting on usability evaluation methods.

Performance evaluation and acceptability of point-of-care Trichomonas vaginalis testing in adult female emergency department patients

We evaluated the accuracy and perception of a patient self-administered, tablet-facilitated rapid Trichomonas vaginalis (TV) point-of-care (POC) test in adult female emergency department (ED) patients.ED patients undergoing gynecologic examination were eligible. Each consented participant self-collected a vaginal swab, performed a tablet-facilitated TV rapid test using the OSOM® Trichomonas Rapid Test, and completed pre- and post-test self-surveys. After the self-test, the clinician collected one standard-of-care (SOC) vaginal swab for wet-mount testing and two for research. The research coordinator performed the TV rapid test using the clinician-collected swab, and reported the results to the clinician and patient. If the self- and coordinator-performed results were discordant, a TV nucleic acid amplification test (NAAT) was performed in a clinical laboratory. A survey was later administered to providers to assess their perceptions of the utility of the POC TV test.Of the 136 participants, 134 (98.5%) completed self-testing; two had invalid results. Comparing coordinator-performed TV rapid test adjudicated with NAAT, the sensitivity and specificity of self-administered test was 96.0% and 100%, respectively. The wet mount had a sensitivity of 52.0% and specificity of 100%. TV detection increased from 9.6% with wet mount to 18.4% with the TV rapid test. Most women (82.0%) stated self-testing was "not at all hard" (versus 66.2% before testing, p < 0.001). Clinicians indicated the TV rapid test affected their clinical management in 48.5% of cases, including 82.6% of positive cases and 41.6% of negative cases.ED patients were able to reliably collect, perform, and interpret their own POC TV test using tablet instructions. Both participants and providers reported high levels of acceptability of POC TV testing, which nearly doubled rates of TV detection.

Establishing the Feasibility of a Tablet-Based Consent Process with Older Adults: A Mixed-Methods Study

Purpose of the Study

This mixed-methods study explored the feasibility and acceptability of using a tablet-based research consent process with adults aged ≥65 years.

Design and Methods

In the first phase, focus group participants reported on their perceptions of a tablet-based consent process. In the second phase, older adults were randomized to view either a tablet-based or paper-based consent for a mock clinical trial. Measurements included: time to complete, adverse/unexpected events, user-friendliness, immediate comprehension, and retention at a 1-week delay.

Results

Focus group participants (N = 15) expressed interest in the novel format, cautioning that peers would need comprehensive orientation to use the technology. In the randomized pilot (N = 20), retention was 100% and all participants completed the protocol without the occurrence of adverse/unexpected events. Although the participants took longer to complete the tablet-based consent than the paper-based version, user-friendliness, immediate comprehension, and retention of the tablet-based consent were similar to the paper-based consent.

Discussion and Implications

The findings suggest that a tablet-based consent process is feasible to implement with older adults and acceptable to this population, but we would underscore that efforts to optimize design of tablet-based consent forms for older adults are warranted.
