Cervical cancer screening rates in the USA fall behind national targets, requiring innovation to circumvent screening barriers. Cervical cancer screening where human papillomavirus (HPV) testing is performed on vaginal samples collected by the patients themselves (self-sampling) are effective and acceptable, and patient-operated rapid HPV tests (self-testing) are currently under development. It is unclear why there is ambivalence toward HPV self-sampling and self-testing among clinicians, an important stakeholder group. We conducted a mixed convergent quantitative and qualitative study to identify the factors influencing clinicians’ attitudes toward self-sampling and self-testing.
Methods:
A survey of Midwest clinicians distributed by professional group media and a market research firm between May and November 2021 was analyzed (n = 248) alongside in-depth interviews with Midwest clinicians from professional groups (n = 23). Logistic regression models examined willingness to support self-sampling and self-testing across respondent characteristics.
Results:
We report that family practice physicians and those in rural areas were more willing to adopt HPV self-sampling (adjusted OR (aOR) = 3.16 [1.43–6.99]; aOR = 2.17 [1.01–4.68]). Clinician willingness to support self-testing was positively associated with current use of self-testing for other conditions and negatively associated with performing 10 or more monthly cervical cancer screenings (aOR = 2.02 [1.03–3.95], aOR = 0.42 [0.23–0.78]). Qualitative data contextualize how clinical specialty and experience with self-sampling and self-testing for other conditions inform clinician perspectives.
Conclusion:
These data suggest clinician populations most accepting of initiatives to implement self-sampling and self-testing for cervical cancer screening and highlight that experience with other forms of self-testing could facilitate more widespread adoption for cervical cancer.
In response to the Omicron surge in early 2022, the HTA Philippines evaluated the acceptability of Filipinos in using self-administered antigen tests (SAAgTs) as part of COVID-19 HTAs in the Philippines.
Methods
Scoping review from literature databases was initially conducted to identify preset codes in the use of SAAgT. Preset codes were used to establish the questions for focus group discussions (FGDs). Semi-structured questionnaires were created through Delphi technique. FGDs with four stakeholder groups (i.e., nine healthcare workers [HCWs], seven representatives of at-risk groups, six economic frontliners, and seven representatives of micro–small–medium-sized enterprises) were conducted.
Results
Discomfort in being a target of stigma and being prescribed an “illness identity” when suspected or confirmed COVID-19-positive, along with lack of confidence to perform self-test, caused hesitancy in self-testing among participants. The need for subsidies for test kits from the government or employers was emphasized to increase its accessibility. Having a designated access point and reporting system for SAAgT was highlighted to avoid nepotism (padrino system attributed to debt of gratitude), inequitable distribution, and lapses in reporting. A participatory approach to education was perceived as crucial to reduce any misconceptions associated with the use of SAAgT.
Conclusions
All FGD groups expressed favorable reviews on the implementation of SAAgT because it can potentially reduce the burden of health facility-administered tests. These findings were considered by the HTA Council in the recommendation of SAAgT as part of the overarching national strategies for the diagnosis and screening of COVID-19.
HIV viral load self-testing could enable people living with HIV (PLHIV) to monitor their viral suppression status more easily, potentially facilitating medication adherence and safe behavior decision-making. Smartphone-based viral load testing innovations have the potential to reach resource-limited and vulnerable communities to address inequities in access to HIV care. However, successful development and translation of these tests requires meaningful investigation of end-user contexts and incorporation of those context-specific needs early in the design process. The objective of this study is to engage PLHIV and HIV healthcare providers in human-centered design research to inform key design and implementation considerations for a smartphone-based HIV viral load self-testing device prototype in development.
Methods:
Semi-structured in-depth interviews were conducted with PLHIV (n = 10) and HIV providers (n = 4) in Indiana, a state with suboptimal viral suppression rates and marked disparities in access to HIV care. Interview guides were developed based on contextual investigation and human-centered design frameworks and included a demonstration of the device prototype with feedback-gathering questions.
Results:
Thematic analysis of interview transcripts revealed important benefits, concerns, and user requirements for smartphone-based HIV VL self-testing within the context of PLHIV lived experience, knowledge, and barriers to care in Indiana.
Conclusion:
End-user needs and preferences were identified as key design specifications and implementation considerations to facilitate the acceptability and inform ongoing development and ultimately real-world translation of the HIV VL monitoring device prototype.
Delegated computation is a two-party task where there is a large asymmetry between the two parties: on the one hand, Alice would like to execute a quantum computation, but she does not have a powerful enough quantum computer to execute it. On the other hand, Bob has a quantum computer, but he is not trusted by Alice. Can Alice make sure that Bob executes her computation correctly for her? In this chapter we present three very different approaches to this problem. Each of the approaches is based on a different model for quantum computation, and the chapter also serves as an introduction to these models.
