RESUMO
Critical drug studies explore the discursive and material dimensions of sexualised drug use to overcome individualised and often pathologising notions such as risk, safety, responsibility and pleasure. This article uses an object-oriented approach-following the use and flow of social apps, syringes and antiretroviral therapy (ART)-to analyse gay and bisexual Taiwanese men's drug practices. Interview data from fourteen men are used to articulate how objects were brought into gay and bisexual men's chemsex repertoire in ways that shaped individuals' safe-sex communication, intimacy maintenance and stigma negotiation. An object-oriented approach scrutinises risk, pleasure and identities in assemblages of the human and nonhuman, and can help identify new opportunities for implementing health promotion interventions and policies.

INTRODUCTION: While various antiretrovirals have been studied as potential candidates for long-acting pre-exposure prophylaxis (PrEP), the bimonthly injectable cabotegravir-the first long-acting form of PrEP-was approved in 2021. Event-driven (ED) PrEP has been the most prevalent dosing regimen among gay, bisexual and other men who have sex with men (GBMSM) in Taiwan, providing a unique setting to observe the preferences for long-acting PrEP in a community where the daily regimen is not the mainstream method. This study aimed to determine the preferences for the different forms and dosing intervals of long-acting PrEP that are currently in the development pipeline. METHODS: We conducted a survey in 2021 by convenience sampling the users of social networking applications for GBMSM in Taiwan. Our survey included questions on sexual behaviours, current PrEP regimens and the preferences for potential candidates of long-acting PrEP, such as implants, intramuscular and subcutaneous injections. We compared the Likert-scale preference ratings for potential long-acting options, and conducted logistic regression analysis to examine the factors associated with a preference for bimonthly intramuscular injections (2M IM) over ED and daily PrEP regimens, respectively. RESULTS: A total of 1728 responses were eligible for analysis. Three percent of respondents (n = 52) were daily PrEP users; 11.5% (n = 198) were ED PrEP users. When not considering cost, current PrEP users-regardless of their original dosing regimen-were most likely to express preferences for monthly oral PrEP, followed by a 6-month subcutaneous injectable (6M SC) and 2M IM. However, among non-current PrEP users, monthly oral PrEP was the most preferred form, followed by ED, daily oral and 6M SC injectable. Multivariable logistic regression revealed that current daily users, those willing to take PrEP in the next 6 months and those with more sex partners in the last 12 months had a significant correlation with preferences for the 2M IM injectable over the ED PrEP. CONCLUSIONS: The monthly oral form was the most preferable long-acting PrEP among GBMSM in Taiwan. Current daily PrEP users preferred the 2M IM injectable over the ED PrEP, which made the 2M IM injectable a potential alternative. Further studies should focus on how the cost and delivery affect PrEP preferences and their actual uptake.

OBJECTIVES: Real-world experience with coformulated bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF) is sparse as a switch regimen among people living with HIV (PLWH) having achieved viral suppression after previous virologic failures with the emergence of K65N/R. METHODS: In this retrospective study, PLWH aged ≥20 years who had previous virologic failures with emergent K65N/R were included for switching to BIC/FTC/TAF after having achieved plasma HIV RNA load (PVL) <200 copies/ml for ≥3 months. PLWH were excluded if integrase inhibitor resistance-associated mutations were detected. The primary end point was losing virologic control (PVL >50 copies/ml) at week 48 using a modified US Food and Drug Administration snapshot algorithm. RESULTS: A total of 72 PLWH with K65N/R who switched to BIC/FTC/TAF were identified. A total of 42 (59.7%) had concurrent M184V/I, and 9 (12.5%) had ≥1 thymidine analog mutations. The median duration of viral suppression was 4.7 years (interquartile range 2.3-5.8), and 97.2% (n = 70) had PVL <50 copies/ml before switching. After a median observation of 98.6 weeks (interquartile range 77.9-120.3), 94.4% (n = 68) continued BIC/FTC/TAF. At week 48, the rate of losing virologic control was 2.8% (2/72). M184V/I was not associated with viral rebound. CONCLUSION: Despite the emergence of K65N/R +/- M184V/I after virologic failures, BIC/FTC/TAF could be an option for simplification after viral suppression.

Numerous studies have identified an association between the use of drugs in sexual contexts (chemsex) and HIV among gay, bisexual, and other men who have sex with men (GBMSM), although whether a causal relationship exists is contentious. An intricate relationship exists between chemsex, HIV treatment and prevention, harm reduction, and the provision of community-grounded health services. Furthermore, potential harms exist beyond HIV, such as intoxication and overdose. Community-engaged responses to chemsex involve social and cultural strategies of harm reduction and sexual health promotion before, during, and after a chemsex session. Ultimately, this Review calls for actions and collaborations aimed at developing a greater understanding of chemsex as a practice within different GBMSM subpopulations and to develop tailored harm-reduction models that can accommodate GBMSM who engage in chemsex in various ways and with varied effects.

Objective: The UPrEPU mobile app is a self-monitoring system to enable men who have sex with men to optimize their pre-exposure prophylaxis adherence for HIV prevention. The app was designed to accommodate a rather complicated event-driven dosing schedule. We aim to evaluate the usability of the UPrEPU app and its effectiveness in improving adherence monitoring. Methods: From May to October 2020, 35 participants were enrolled for the usability study and followed up for 4 months. Blood samples for the drug concentration in the dried blood spots were obtained once during the second to fourth follow-up visits. The effectiveness of adherence monitoring was analyzed using Cohen's kappa statistic to calculate the concordance between the average number of pills taken and drug concentration in the dried blood spots. Results: Overall retention was 91.4% (32 participants) at the end of the study. Participants used the app for a mean of 29 days and made 2565 data entries in total, with an average of 76 data entries. The average systematic usability scale score for the app was 71.5, indicating acceptable usability. Slight agreement was reached between the dried blood spots measurement and the number of pills taken and recorded in the app (weighted kappa: 0.21). Conclusions: Our user-centered UPrEPU app demonstrated that it could accommodate both daily and event-driven dosing schedules for men who have sex with men clients with acceptable usability scores. We confirmed that complex behaviors such as different drug-dosing regimens that are contingent on sexual behaviors could be incorporated into the design of a mobile app.
RESUMO
BACKGROUND: Atherosclerosis and vascular inflammatory response have been considered as risk factors for non-typhoidal Salmonella (NTS) vascular infection. The study aims to assess the risk of vascular infection by measuring atherosclerosis severity, NTS vascular infection (NTSVI) score, and serum levels of inflammatory markers in people with NTS bacteremia. METHODS: A prospective observational study was conducted in two medical centers and two regional hospitals. Adults aged ≥50 years with NTS bacteremia who underwent computed tomography (CT) scan for revealing vascular infections were enrolled. The degree of atherosclerosis was scaled by a calcium score determined by a CT scan. Serum concentrations of inflammatory biomarkers were determined in the patients enrolled in a medical center. RESULTS: Fourteen (20.3%) of 69 patients with NTS bacteremia had vascular infections. Calcium scores over the thoracic (12,540 vs. 3,261, P = 0.0005) and abdominal (9755 vs. 3,461, P = 0.0006) aorta of those with vascular infections were higher than those without vascular infection. All vascular infections were present in the high-risk group (NTSVI score ≥1), yielding a sensitivity of 100% and specificity of 30.9%. Among 17 low-risk patients (NTSVI score <1), none had vascular infections, resulting in a negative predictive value of 100%. Higher plasma concentrations of IL-1ß were detected in the cases of vascular infection than those in the control group (23.6 vs. 1.06 pg/mL, P = 0.001). CONCLUSION: Atherosclerosis of the aorta which is associated with a positive NTSVI score can predict the occurrence of vascular infections and serum IL-1ß could be a biomarker for vascular infection in patients with NTS bacteremia.

BACKGROUND: New innovative technologies, such as mobile apps, have been developed to increase pre-exposure prophylaxis (PrEP) adherence and the use of log sex diaries. The contiguity of mobile apps reduces the recall bias that generally affects reported condom and PrEP use. However, none of the currently used mobile apps were designed for event-driven PrEP users, and few studies have demonstrated the potential usage of sex diary data to facilitate the understanding of the different HIV risks among heterogeneous profiles of sex diaries and PrEP use. OBJECTIVE: We aim to discriminate the heterogeneous profiles of sex events and PrEP use and examine the risk of condomless anal sex among different types of sex events. METHODS: We recruited 35 adult men who have sex with men from two medical centers in Taiwan since May 2020 and followed up for four months. Participants were on PrEP or willing to take PrEP. They were asked to log their sex events, PrEP use, and dosing regimens on a mobile app to improve their PrEP adherence. Latent class analysis was used to distinguish profiles of sex events and PrEP use. Indicators included correct intake of PrEP for each sex event, participants' sexual positioning, partner's HIV status, and age. RESULTS: A total of 551 sex events were classified into three classes by latent class analysis: PrEP nonadherent flip-flopping (234/551, 42%), PrEP imperfect-adherent power bottoming (284/551, 52%), and PrEP adherent serodiscordant topping (33/551, 6%). "PrEP nonadherent flip-flopping" sex events were more likely to involve condomless anal sex than "PrEP imperfect-adherent power bottoming" (OR 1.83, 95% CI 1.03-3.25) after considering random intercepts for individuals, and this class needed to increase their PrEP adherence and use of condoms. "PrEP imperfect-adherent power bottoming" realized their own risk and packaged PrEP with condoms to protect themselves. Up to 99% (32/33) of sex events in "PrEP adherent serodiscordant topping" were protected by PrEP, but all of the sex events in this group were condomless. CONCLUSIONS: Using the sex diary data could advance the capacity to identify high-risk groups. HIV prevention strategy should be more flexible and combine PrEP with condom use for future HIV prevention.

(1) Background: This study aimed to determine the association between the use of efavirenz and depressive disorders among human immunodeficiency virus (HIV)-infected patients. (2) Methods: A retrospective cohort study was conducted using Taiwan's National Health Insurance Database. We identified patients receiving anti-retroviral therapy (ART) between 2000 and 2009; these patients were followed until 2010 for diagnoses of depressive disorders using the Cox proportional hazard model to estimate hazard ratios. (3) Results: After up to 11 years of follow-up, the incidence of depressive disorders for the efavirenz-treated group was estimated at 12.2/1000 person-years (PYs), and the control group was at 12.5/1000 PY (p = 0.822). The independent risk factors for depressive disorders included an insurance premium of less than NTD 17,820 (New Taiwan Dollars-NTD) (adjusted hazard ratio (aHR) 2.59, 95% confidence interval (CI), 1.79-3.76, p < 0.001), and between NTD 17,821 and NTD 26,400 (aHR 1.55, 95% CI, 1.04-2.31, p = 0.030), living in Southern Taiwan (aHR 1.49, 95% CI, 1.21-1.84, p = 0.002), and with a psychiatric history (excluding depressive disorders) (aHR 4.59, 95% CI, 3.51-6.01, p = 0.030). (4) Conclusions: This study concluded that ART-treated patients with a past history of psychiatric disorders, lower insurance premium, and living in Southern Taiwan have an increased risk of depressive disorders, which are not associated with the use of efavirenz.
RESUMO
In response to the COVID-19 pandemic, Taiwan has been one of the best performers in the world with extremely low infections and deaths. This success can be attributed to the long experiences dealing with natural disasters and communicable diseases. However, with different disastrous characteristics, the disaster management systems for communicable diseases and natural disasters are very different in terms of laws, plans, frameworks, and emergency operations. Taking the response to COVID-19 pandemic as a study subject, we found that disaster management for communicable diseases can be improved through a comparison with natural disasters, and vice versa. First, having wider and longer impacts than natural disasters, the plans and framework for communicable diseases in Taiwan focus more on national and regional scales. Local governments would need more capacity support including budgets and training to conduct investigations and quarantine during the COVID-19 pandemic. Second, for quick response, the emergency operation for communicable diseases was designed to be more flexible than that for natural disasters by giving the commander more authority to adjust to the circumstances. The commanding system requires a more objective consultation group to prevent arbitrary decisions against the COVID-19 pandemic. Finally, risk governance is important for communicable diseases as well as for natural disasters. Additional efforts should be made to enhance vulnerability assessment, disaster reduction, and risk communication for shaping responses and policies in an efficient and coordinating way.

This prospective study aimed to investigate the clinical and microbiological characteristics of different Aeromonas species. Clinical isolates of Aeromonas species between 2016 to 2018 were collected in a university hospital in southern Taiwan. The species was determined by rpoD or gyrB sequencing. A total of 222 Aeromonas isolates from 160 patients in 164 episodes were identified. The crude in-hospital mortality was 17.2%. The most frequently isolated species was Aeromonas veronii (30.6%), followed by A. caviae (24.8%), A. hydrophila (23%), and A. dhakensis (16.7%). The major clinical manifestations were primary bacteremia (31.1%), skin and soft tissue infection (22.6%), and biliary tract infection (18.3%). The most common underlying diseases were malignancy (45.1%), diabetes mellitus (27.4%), and liver cirrhosis or chronic hepatitis (26.2%). A. hydrophila and A. dhakensis predominated in the skin and soft tissue infection (p<0.0001), whereas A. vernoii and A. caviae prevailed in primary bacteremia and biliary tract infections (p=0.012). Pneumonia, malignancy, and ascF-ascG genotype were independent factors associated with mortality. Ertapenem susceptibility was decreased in A. sobria (42.9%), A. veronii (66.7%), A. dhakensis (73%), and A. hydrophila (84.3%). Cefotaxime resistance was found in 30.9% of A. caviae and 18.9% of A. dhakensis isolates, much more prevalent than the other species. The metallo-ß-lactamase blaCphA was almost invariably present in A. dhakensis, A. hydrophila, and A. veronii (100%, 100% and 89.9%, respectively). Amp-C ß-lactamases such as blaMOX and blaAQU-1 were identified in all A. caviae and 91.9% of A. dhakensis isolates. Cefepime, fluoroquinolones and tigecycline showed good in vitro activity against aeromonads.

INTRODUCTION: Both daily and event-driven (ED) pre-exposure prophylaxis (PrEP) have been demonstrated to be highly effective among men who have sex with men (MSM). Prevention-effective adherence proposes that PrEP adherence should be aligned with the risk of HIV, which could be applied to both daily and ED PrEP adherence measurement. The objective of this study was to describe the relationship between the use of PrEP and sex events among the MSM PrEP users and identify factors associated with adherence among daily and ED MSM PrEP users. METHODS: A multicentre, observational, prospective cohort study was conducted at three hospital-based clinics in three urban cities of Taiwan from January 2018 to December 2019. MSM ages 18 years or older - at high risk of HIV acquisition and taking PrEP during the study period - were included in the analysis. MSM PrEP users were allowed to choose between daily and ED PrEP based on their preference. Data on sociodemographic characteristics, mental health, sexual behaviours, substance use and PrEP-taking behaviours were collected at each visit. RESULTS: A total of 374 MSM were included in the analysis with 1,054 visits. More than half (56%) of the PrEP users chose ED at the baseline and 150 regimen switches were reported by 21% of the participants. There was only one seroconversion documented during the study period. Most (84.2%) of the MSM PrEP users were able to adhere to PrEP during the most recent anal intercourse in the past one month. Among ED PrEP users with suboptimal adherence, the majority (81.9%) missed the pre-coital dose. In the multivariable analysis, we found that participants who switched from daily to an ED dosing regimen were associated with poorer adherence to PrEP. CONCLUSIONS: A high level of PrEP adherence was observed among the majority of MSM in a real-world setting. On the other hand, Taiwanese MSM switching from daily to ED dosing regimens were less likely to adhere to PrEP, suggesting that novel approaches focusing on a dosing switch would be necessary for MSM to improve their adherence to PrEP.

BACKGROUND: Sexualized drug use or "chemsex" in Taiwan commonly incorporates the use of methamphetamine. Our study aimed to assess the extent of severity of dependence of methamphetamine among MSM in Taiwan as well as motivations for engagement in chemsex. METHODS: Direct messages were sent to users of a large MSM social networking application in Taiwan between November 2018 and January 2019. MSM who had at least one experience of using drugs during sex in the preceding 12 months were invited to complete an online survey that assessed their sexual behavior, substance use and motivations for engaging in chemsex. The Severity of Dependence Scale was used to assess methamphetamine dependency. Multivariable logistic regression was used to determine the factors associated with methamphetamine dependency. RESULTS: From a total of 1906 responses, 517 had used methamphetamine in their lifetime and were included in the analysis. The majority (87.2%) used more than one substance when engaging in chemsex in the past six months, while a quarter reported injection of methamphetamine within the last six months. The most commonly reported motivations for participants to engage in chemsex were to have fun, for relaxation, and to increase the intensity of the sexual experience. Nearly half (46.0%) exhibited signs of methamphetamine dependency. Lower monthly income, injection of methamphetamine, ever feeling lonely in the past 3 months and concerns about their substance use expressed by others were significantly associated with methamphetamine dependency. CONCLUSION: A high proportion of MSM population who engaged in chemsex were at risk of developing methamphetamine dependency. While motivations for engaging in chemsex were diverse and suggest potential for enhanced sexual experience for some, community health organization for gay men's health and healthcare providers should be vigilant at identifying the risk of methamphetamine dependency and provide in-time, brief intervention or referrals when needed.

BACKGROUND: Intracranial arachnoid cysts (AC) are benign, cerebrospinal fluid filled spaces within the arachnoid layer of the meninges. Neurosurgical intervention in children and young adults has been extensively studied, but the optimal strategy in the elderly remains unclear. Therefore, we performed a single center retrospective study combined with a systematic review of the literature to compare cystoperitoneal (CP) shunting with other surgical approaches in the elderly cohort. METHODS: Retrospective neurosurgical database search between January 2005 and December 2018, and systematic review of the literature using PRISMA guidelines were performed. Inclusion criteria: Age 60 years or older, radiological diagnosis of intracranial AC, neurosurgical intervention, and neuroradiological (NOG score)/clinical outcome (COG score). Data from both sources were pooled and statistically analyzed. RESULTS: Our literature search yielded 12 studies (34 patients), which were pooled with our institutional data (13 patients). CP shunts (7 patients; 15%), cyst fenestration (28 patients; 60%) and cyst marsupialisation/resection (10 patients; 21%) were the commonest approaches. Average duration of follow-up was 23.6, 26.9, and 9.5 months for each approach, respectively. There was no statistically significant association between choice of surgical intervention and NOG score (P = 0.417), COG score (P = 0.601), or complication rate (P = 0.955). However, CP shunting had the lowest complication rate, with only one patient developing chronic subdural haematoma. CONCLUSION: CP shunting is a safe and effective surgical treatment strategy for ACs in the elderly. It has similar clinical and radiological outcomes but superior risk profile when compared with other approaches. We advocate CP shunting as first line neurosurgical intervention for the management of intracranial ACs in the elderly.
RESUMO
When provided with both choices of pre-exposure prophylaxis (PrEP) in MSM, men may choose to use either method based on their sexual practice. The study objective was to describe the switches between dosing regimens and identify factors that predict choice of a dosing regimen among MSM. We performed a multi-center, observational, prospective PrEP cohort study conducted at three study sites in Taiwan between January 2018 and March 2019. A total of 215 participants made 469 visits. In half of the visits (49.7%), participants reported using on-demand PrEP. There were 36 regimen switches: 20 from daily to on-demand and 16 from on-demand to daily. Among 28 participants who switched regimens, 22 switched regimens once and 6 switched more than once. The frequency of condomless anal sex and a history of post-exposure prophylaxis use were associated with taking PrEP on-demand (p < 0.05). PrEP adherence intervention should be tailored specifically to sexual behavior to increase adherence to PrEP.
RESUMEN: Cuando se les proporcionan ambas opciones de la profilaxis pre-exposición (PrEP) en HSH, los hombres pueden elegir usar cualquiera de los métodos según su práctica sexual. El objetivo del estudio fue describir los cambios entre los regímenes de dosificación e identificar los factores que predicen la elección del régimen de dosificación entre los HSH. Realizamos un estudio de cohorte prospectivo, observacional y multicéntrico de la PrEP realizado en tres sitios de estudio en Taiwán entre enero de 2018 y marzo de 2019. Un total de 215 participantes contribuyeron con 469 visitas. En la mitad de las visitas (49.7%), los participantes informaron haber usado PrEP a pedido. Hubo 36 cambios de régimen: 20 de diario a pedido y 16 de pedido a diario. Entre los 28 participantes que cambiaron de régimen, 22 cambiaron de régimen una vez y 6 cambiaron más de una vez. La frecuencia del sexo anal sin condón y cualquier uso previo de la PEP fueron asociados con la toma de la PrEP a pedido (p < .05). La intervención de adherencia a la PrEP debe adaptarse específicamente al comportamiento sexual para aumentar la adherencia a la PrEP.

BACKGROUND/PURPOSE: This multicenter study aimed to evaluate the seroprevalence of hepatitis B virus (HBV) and the use of combination antiretroviral therapy (cART) among patients receiving HIV care in Taiwan. METHODS: We retrospectively reviewed the medical records of HIV-infected adult patients who initiated cART at 11 designated hospitals in Taiwan between 2012 and 2016. The clinical information collected included serological profiles on HBV, hepatitis C virus (HCV), and syphilis, plasma HIV RNA load, nadir CD4 cell count, and antiretrovirals with activity against both HBV and HIV (tenofovir disoproxil fumarate [TDF], lamivudine [LAM], and emtricitabine [FTC]). RESULTS: We analyzed 1800 HIV-infected patients; 1742 (96.8%) were male and 794 (44.1%) were born after July, 1986, when nationwide universal neonatal HBV vaccination was implemented. HBsAg positive results were 11.6% (209/1800), which decreased significantly from 18.1% (182/1006) in those born before July 1986 to 3.4% (27/794) in those born after. In multivariable analysis, HBsAg positivity was significantly associated with age (adjusted odds ratio [aOR] 1.06, 95% confidence interval [CI] 1.05-1.08), CD4â§200 cells/µL (aOR 0.73, 95% CI 0.53-0.99), and HCV seropositivity (aOR 1.62, 95% CI 1.06-2.50). Of 209 HBV/HIV-coinfected patients, 31.1% started cART containing only LAM with anti-HBV activity, while 68.9% started cART containing TDF plus LAM or coformulated TDF/FTC. CONCLUSIONS: The overall prevalence of HBV/HIV coinfection remained high among HIV-infected patients in Taiwan. Despite recommendations of the HIV treatment guidelines for the management of HBV infection, a substantial proportion of HIV/HBV-coinfected patients received cART containing only LAM for HBV infection.

The application of cefepime breakpoint for carbapenem-resistant Klebsiella pneumoniae (CRKP) bacteraemia has not been explored. Adult cases of monomicrobial bloodstream infection (BSI) caused by cefepime-susceptible [minimum inhibitory concentration (MIC) ≤8 mg/L] K. pneumoniae isolates with carbapenem resistance between 2010 and 2015 were reviewed. Patients treated with cefepime were compared with those treated by other active agents using a propensity score-matched analysis to assess therapeutic effectiveness. The primary endpoint was 30-day crude mortality. A total of 114 patients experienced cefepime-susceptible CRKP bacteraemia and 40 (35.1%) died during hospitalisation. A total of 33 patients (28.9%) received cefepime therapy. Fifteen patients (13.2%) had BSI due to carbapenemase-producing isolates, and 86.7% (13/15) of carbapenemase-producing isolates were classified as cefepime susceptible dose-dependent (SDD). In the multivariate logistic regression analysis, 30-day mortality was independently associated with the presence of a critical illness [adjusted odds ratio (aOR) = 12.89, 95% confidence interval (CI) 3.88-42.83; P < 0.001], pneumonia (aOR = 5.97, 95% CI 1.65-21.76; P = 0.007) and rapidly fatal underlying disease (aOR = 6.43, 95% CI 1.30-31.09; P = 0.02). In contrast, cefepime-based therapy (aOR = 0.03, 95% CI 0.003-0.38; P = 0.006) and combination therapy (aOR = 0.09, 95% CI 0.02-0.36; P = 0.001) were protective against a fatal outcome. Based on current breakpoints for Enterobacterales, cefepime therapy was not associated with an unfavourable outcome for CRKP BSI with MIC-based dosing strategies. However, the susceptibility result of SDD to cefepime should alert clinicians for possible therapeutic failure.

BACKGROUND: Daily and on-demand pre-exposure prophylaxis (PrEP) has been well demonstrated to effectively prevent HIV acquisition for men who have sex with men (MSM). More than half of the MSM PrEP users in Taiwan prefer on-demand PrEP; however, on-demand PrEP involves a complicated dosing regimen because it requires precoital and postcoital dosing and sex events are hard to anticipate. Although there are a growing number of mobile apps designed to improve access to HIV prevention services and HIV medication adherence, few mobile apps focus on adherence to PrEP or are designed to accommodate a complicated, on-demand PrEP dosing schedule. OBJECTIVE: The aim of this project is to evaluate the usability of a newly developed mobile app (UPrEPU) to assist MSM PrEP users to self-monitor their adherence to either daily or on-demand PrEP using a user-centered scheme. METHODS: This research will be conducted in 2 phases: app development and usability study. In the app development phase, we will first conduct formative research with end users and stakeholders through in-depth interviews; the results will provide PrEP users' and PrEP navigators' personas as material used in the app conceptualization stage. PrEP navigators are individuals in the health care system that help HIV-negative individuals who need assistance in accessing PrEP care. A low-fidelity prototype of the app feature will be formatted by applying a participatory design approach to engage PrEP users, designers, and app developers in the design process of the app. Then, a high-fidelity prototype of the app will be developed for the usability study and refined iteratively by the multidisciplinary team and new internal testers. Internal testers include the research team consisting of experts in public health, infectious disease, and industrial design and a close network of the research team that is taking PrEP. In the usability study phase, we will enroll 70 MSM PrEP users and follow them up for 4 months. Usability, feasibility, and effectiveness of adherence monitoring will be evaluated. RESULTS: Refinement of the UPrEPU app is currently ongoing. The usability study commenced in May 2020. CONCLUSIONS: The UPrEPU app is one of the first apps designed to help MSM PrEP users to self-manage their PrEP schedule better regardless of dosing modes. With a design-thinking approach and adapting to the cultural context in Taiwan's MSM population, this novel app will have substantial potential to be acceptable and feasible and contribute to the reduction of new HIV infections.
