Client and staff perceptions of acceptability of MyCheck: a direct-to-pathology telehealth and e-testing service for comprehensive bloodborne virus and sexually transmissible infection screening.

Background Sydney Sexual Health Centre (SSHC) is the largest sexual health clinic in New South Wales (NSW), servicing clients at high risk of sexually transmissible infections and bloodborne viruses. SSHC piloted a direct-to-pathology pathway that facilitated bloodborne virus/sexually transmissible infection testing at one of the ~500 participating pathology collection centres located across NSW. This qualitative study sought to understand SSHC client and provider perspectives of acceptability of the MyCheck intervention. Methods Semi-structured in-depth interviews were conducted with 11 clients who underwent testing via the MyCheck pathway and eight staff members involved in implementing MyCheck. The seven components of Sekhon's Theoretical Framework of Acceptability informed this analysis. Results Participants broadly conveyed 'affective attitude' toward the MyCheck pathway. The telehealth intervention reduced client 'burden' and 'opportunity cost' through enabling greater testing convenience at a location suitable to them and provided timely results. Issues of 'ethicality' were raised by clients and staff as pathology centre staff were, on a few occasions, regarded as being judgmental of SSHC clients. 'Intervention coherence' issues were largely attributed to pathology centre personnel being unfamiliar with the intervention, with billing issues being a recurrent concern. Participants perceived MyCheck as an 'effective' testing pathway. SSHC staff were able to offer the intervention with ease through seamless IT integration ('self-efficacy'). Conclusion The MyCheck intervention was perceived by both SSHC clients and staff as an acceptable bloodborne virus/sexually transmissible infection testing pathway. However, further work is required to address stigma experienced by some clients when attending pathology collection centres.

Insights from the scale-up and implementation of the Deadly Liver Mob program across nine sites in New South Wales, Australia, according to the RE-AIM framework.

BACKGROUND: The Deadly Liver Mob (DLM) program is a peer-led health promotion program that aims to improve access to screening and treatment for blood borne viruses and sexually transmissible infections for Aboriginal and Torres Strait Islander Australians. In this paper, we used client and staff insights to explore the successes and challenges of implementing the DLM program according to the RE-AIM framework, which explores real-world implementation of interventions according to reach, effectiveness, adoption, implementation, and maintenance. METHODS: Clients and staff were recruited through the DLM program. Semi-structured interviews were conducted with four Aboriginal and Torres Strait Islander and 11 non-Aboriginal or Torres Strait Islander health workers, as well as 33 Aboriginal and Torres Strait Islander clients of the program. RESULTS: Findings show the positive effects of the DLM program, in creating a culturally safe and sensitive environment for Aboriginal and Torres Strait Islander clients to access care. In particular, the employment of frontline Aboriginal and Torres Strait Islander workers to deliver the education was touted as one of the primary successes of the program, in enabling workers to build trust between clients and mainstream health systems, which has the flow on effect of encouraging clients to go through to screening. The use of the RE-AIM framework illustrates the challenges of implementing real-world interventions across various locations, such as the difficulties in delivering DLM in regional and remote areas due to covering large geographic areas with minimal public transport available. CONCLUSIONS: The data emphasise the need for interventions to be adaptable and flexible, altering elements of the program to suit local and community needs, such as by offering mobile and outreach services to enable access across regional and rural areas. The findings of this evaluation have been used to develop tools so that the learnings from DLM can be shared with others who may be hoping to implement DLM or other similar programs.

Evaluating a complex health promotion program to reduce hepatitis C among Aboriginal and Torres Strait Islander peoples in New South Wales, Australia: the Deadly Liver Mob.

The Deadly Liver Mob (DLM) is a peer-delivered incentivised health promotion program by and for Aboriginal and Torres Strait Islander Australians, and was introduced in response to the disproportionate number of Aboriginal and Torres Strait Islander Australians who are impacted by blood borne viruses (BBVs) and sexually transmitted infections (STIs). The goal of the program is to increase access to BBV and STI education, screening, treatment, and vaccination in recognition and response to the systemic barriers that Aboriginal and Torres Strait Islander peoples face in accessing health care. This commentary introduces a series of papers that report on various aspects of the evaluation of the Deadly Liver Mob (DLM) program. In this paper, we explain what DLM is and how we constructed an evaluation framework for this complex health promotion intervention.

Increasing access to screening for blood-borne viruses and sexually transmissible infections for Aboriginal and Torres Strait Islander Australians: evaluation of the Deadly Liver Mob program's 'cascade of care' across nine sites in New South Wales, Australia.

BACKGROUND: Aboriginal and Torres Strait Islander Australians are disproportionately impacted by blood-borne viruses (BBVs) and sexually transmissible infections (STIs). Stigma remains one of the key barriers to testing and treatment for BBVs and STIs, particularly among Aboriginal and Torres Strait Islander people. The Deadly Liver Mob (DLM) is a peer-delivered incentivised health promotion program by and for Aboriginal and Torres Strait Islander Australians. The program aims to increase access to BBV and STI education, screening, treatment, and vaccination for Aboriginal and Torres Strait Islander Australians in recognition of the systemic barriers for First Nations people to primary care, including BBV- and STI-related stigma, and institutional racism. This paper presents routinely collected data across nine sites on the 'cascade of care' progression of Aboriginal and Torres Strait Islander clients through the DLM program: hepatitis C education, screening, returning for results, and recruitment of peers. METHODS: Routinely collected data were collated from each of the DLM sites, including date of attendance, basic demographic characteristics, eligibility for the program, recruitment of others, and engagement in the cascade of care. RESULTS: Between 2013 and 2020, a total of 1787 Aboriginal and Torres Strait Islander clients were educated as part of DLM, of which 74% went on to be screened and 42% (or 57% of those screened) returned to receive their results. The total monetary investment of the cascade of care progression was approximately $56,220. Data highlight the positive impacts of the DLM program for engagement in screening, highlighting the need for culturally sensitive, and safe programs led by and for Aboriginal and Torres Strait Islander people. However, the data also indicate the points at which clients 'fall off' the cascade, underscoring the need to address any remaining barriers to care. CONCLUSIONS: The DLM program shows promise in acting as a 'one stop shop' in addressing the needs of Aboriginal and Torres Strait Islander people in relation to BBVs and STIs. Future implementation could focus on addressing any potential barriers to participation in the program, such as co-location of services and transportation.

Evaluating the Impact of the COVID-19-Related Public Health Restrictions on Access to Digital Sexually Transmitted and Blood-Borne Infection Testing in British Columbia, Canada: An Interrupted Time Series Analysis.

BACKGROUND: Evidence of long-term impacts of COVID-19-related public health restrictions on digital sexually transmitted and blood-borne infection (STBBI) testing utilization is limited. We assessed these impacts on GetCheckedOnline (a digital testing resource for STBBIs) relative to all STBBI tests in British Columbia (BC). METHODS: Interrupted time series analyses were conducted using GetCheckedOnline program data comparing monthly test episodes (STBBI tests per requisition) among BC residents, stratified by BC region, and testers' sociodemographic and sexual risk profiles, for the prepandemic (March 2018-February 2020) and pandemic periods (March 2020-October 2021). Trends in GetCheckedOnline testing per 100 STBBI tests in BC regions with GetCheckedOnline were analyzed. Each outcome was modeled using segmented generalized least squared regression. RESULTS: Overall, 17,215 and 22,646 test episodes were conducted in the prepandemic and pandemic periods. Monthly GetCheckedOnline test episodes reduced immediately after restrictions. By October 2021 (end of the pandemic period), monthly GetCheckedOnline testing increased by 21.24 test episodes per million BC residents (95% confidence interval, -11.88 to 54.84), and GetCheckedOnline tests per 100 tests in corresponding BC regions increased by 1.10 (95% confidence interval, 0.02 to 2.17) above baseline trends. After initial increases among users at higher STBBI risk (symptomatic testers/testers reporting sexual contacts with STBBIs), testing decreased below baseline trends later in the pandemic, whereas monthly GetCheckedOnline testing increased among people 40 years or older, men who have sex with men, racialized minorities, and first-time testers via GetCheckedOnline. CONCLUSIONS: Sustained increases in utilization of digital STBBI testing during the pandemic suggest fundamental changes in STBBI testing in BC, highlighting the need for accessible and appropriate digital testing, especially for those most affected by STBBIs.

The effect analysis and prevention effects of nucleic acid testing combined with enzyme linked immunosorbent assay on blood-borne diseases.

To investigate the effect analysis and preventive effects of nucleic acid testing combined with enzyme-linked immunosorbent assay (ELISA) on blood-borne diseases. This study included 72335 blood samples that were collected in our hospital from March 2019 to March 2020. All the samples were tested for anti HIV (AIDS antibody), anti HCV (hepatitis C antibody), HBsAg (hepatitis B surface antigen) and anti TP (syphilis antibody) in blood respectively with two manufacturers' reagents. The results of anti HIV, anti HCV, HBsAg and anti TP of all samples were analyzed, and blood samples with 0.7< sample test value / critical value (s / CO) < 3.0 were tested by ELISA and negative blood samples were tested by ELISA and nucleic acid testing. Then we analyzed the results of nucleic acid testing. 610 blood samples failed to pass the test of anti HIV, anti HCV, HBsAg and anti TP ELISA, accounting for 0.84% of the total numbers, including 100 blood samples with 1.0 3.0, 338 blood samples with 0.7< s/CO <1.0 and 71725 blood samples were qualified. We used nucleic acid testing to test 71725 qualified samples tested by ELISA and then there were 50 samples with positive HBV-DNA , accounting for 0.07% (50 / 71725), no one with positive HIV-RNA and positive HCV-RNA, accounting for 0.00% (0/71725). The positive rate of blood samples with HBsAg 0.7

Assessing an Adaptation of the Universal Parasite Diagnostic Assay for Bloodborne Parasites in a US State Public Health Laboratory.

For complex clinical cases where a parasitic infection is suspected, it can be difficult for clinicians to recommend an appropriate laboratory test. These tests are usually pathogen-specific and require a certain degree of suspicion for the precise etiology. A recently described assay, the universal parasite diagnostic (UPDx) can potentially provide a diagnosis of any parasite present in a specimen. Using primers that amplify DNA from all eukaryotes, UPDx differentiates several parasitic infections in blood by amplicon-based next-generation sequencing (NGS) of the 18S rDNA locus. As the state's public health reference laboratory, the Parasitology Laboratory at the Wadsworth Center (Albany, NY) receives specimens from patients who have potentially encountered a wide variety of parasites. As such, the ability to differentiate several blood parasites using a single assay is of interest. We assessed UPDx for its ability to confirm parasitic infections for 20 specimens that were previously identified by real-time PCR (RT-PCR). This included specimens positive for Babesia microti, Trypanosoma cruzi, Leishmania tropica, various Plasmodium species, and specimens comprising mixed Plasmodium sp. infections. Results obtained using UPDx were largely concordant with the RT-PCR assays. A T. cruzi positive specimen was negative by UPDx and for two mixed Plasmodium sp. infections only one species was detected. The results obtained for other specimens were concordant. We conclude that UPDx shows promise for the detection of blood parasites in diagnostic laboratories. As NGS becomes cheaper, assays like UPDx will become increasingly amenable to use in clinical settings.

The risk of blood-borne infections in Poland - opportunities and threats to public health, nationwide qualitative research.

INTRODUCTION: The article presents the diagnosis of the problem of blood-borne infections in Poland from perspectives of experts' opinions at the voivodship level. The evaluation became the basis for subsequent analysis, aimed at creating assumptions for the proposed strategies to prevent blood-borne infections in Poland. MATERIAL AND METHODS: Diagnosis was based on the expertise of practitioners in epidemiology and service providers. Analysis covered assessment of service safety, examples, recommended practices, forms and scope of education. Also covered is information for the general public from different aspects: points of view of recipients and service providers, legislation, system organization, and finances. The SWOT method was used in analysis. The opportunities and threats concerning the risk of blood-borne diseases for the service sector are presented, as well as data gathered from 42 representative experts from across Poland. RESULTS: Databases on health indicators, covered by the reporting obligation of all diagnosed cases, are a crucial element of the surveillance system in public health (e.g. sentinel). Additional information on health care management (risk management) is not a common and routine approach. The study fills a gap in knowledge about risk management in the medical and non-medical services sector. The information also enriches education programmes (e.g. http://www.hcv.pzh.gov.pl/). CONCLUSIONS: Currently, the evidence-based approaches in medicine and in public health are standard. Experts emphasize that the opportunities for the prevention of infection risk are linked to technological advances and innovations, while threats are seen in both financial and organizational constraints, and the non-normalized, dynamically developing service market.

Infectious diseases screening approach among refugees: results from a single-center study.

INTRODUCTION: Our aim was to evaluate a screening program, with active case-finding and treatment for active tuberculosis (TB), latent tuberculosis infection (LTBI), blood-borne viruses (BBV), and sexually transmitted diseases (STDs) among refugees living in facility centers. METHODOLOGY: We collected data on refugees arriving to our attention in migrant centers in Sardinia, Italy. Socio-demographical data, anamnesis, and clinical features were collected. TST Mantoux was conducted, and X-ray chest (XRC) was performed if TST was positive. Blood-borne virus screening was proposed to all patients. Screening for STDs was offered according to guidelines, anamnesis, and physical examination. RESULTS: Eighty-one patients were included. Seventy (86.4%) were male, and the mean age was 24.8±5.7 years. Thirty-three (40.7%) had scabies. Overall, 40/81 (49.4%) had a positive TST Mantoux. One (2.5%) was hospitalized and died for multi-drug-resistant TB. One (2.5%) patient had intestinal-TB. 52/81 (64.2%) refused HIV screening, whereas no positivity was found among tested migrants. Sixty-two (76.5%) accepted HCV screening, and one (1.6%) had a positive test. Fifty-eight (71.6%%) accepted HBV testing, and 29 (50%) of them had positive serology. Ten (12.3%) patients had anal or genital lesions due to syphilis, Molluscum contagiosum, and HPV in 7 (70%), 2 (20%), and one (10%) case, respectively. CONCLUSIONS: Infectious diseases control and prevention are a key strategy among refugees. The stay in a migrant center is an extraordinary occasion for healthcare provision. This condition could allow a broad screening program in which quick BBV screening tests could be a good method to implement uptake. More information and educational programs would allow a higher understanding and acceptance of HIV screening.

How can we make self-sampling packs for sexually transmitted infections and bloodborne viruses more inclusive? A qualitative study with people with mild learning disabilities and low health literacy.

OBJECTIVES: 1.5 million people in the UK have mild to moderate learning disabilities. STIs and bloodborne viruses (BBVs) are over-represented in people experiencing broader health inequalities, which include those with mild learning disabilities. Self-managed care, including self-sampling for STIs/BBVs, is increasingly commonplace, requiring agency and health literacy. To inform the development of a partner notification trial, we explored barriers and facilitators to correct use of an STI/BBV self-sampling pack among people with mild learning disabilities. METHODS: Using purposive and convenience sampling we conducted four interviews and five gender-specific focus groups with 25 people (13 women, 12 men) with mild learning disabilities (July-August 2018) in Scotland. We balanced deductive and inductive thematic analyses of audio transcripts to explore issues associated with barriers and facilitators to correct use of the pack. RESULTS: All participants found at least one element of the pack challenging or impossible, but welcomed the opportunity to undertake sexual health screening without attending a clinic and welcomed the inclusion of condoms. Reported barriers to correct use included perceived overly complex STI/BBV information and instructions, feeling overwhelmed and the manual dexterity required for blood sampling. Many women struggled interpreting anatomical diagrams depicting vulvovaginal self-swabbing. Facilitators included pre-existing STI/BBV knowledge, familiarity with self-management, good social support and knowing that the service afforded privacy. CONCLUSION: In the first study to explore the usability of self-sampling packs for STI/BBV in people with learning disabilities, participants found it challenging to use the pack. Limiting information to the minimum required to inform decision-making, 'easy read' formats, simple language, large font sizes and simpler diagrams could improve acceptability. However, some people will remain unable to engage with self-sampling at all. To avoid widening health inequalities, face-to-face options should continue to be provided for those unable or unwilling to engage with self-managed care.

Awareness of and intention to use an online sexually transmitted and blood-borne infection testing service among gay and bisexual men in British Columbia, two years after implementation.

OBJECTIVES: This study assessed gay, bisexual, and other men who have sex with men's (GBMSM) awareness of and intention to use GetCheckedOnline, an online sexually transmitted and blood-borne infection (STBBI) testing service. METHODS: A cross-sectional study was conducted two years after launch among GBMSM > 18 years of age in British Columbia, Canada. Participants were recruited through community venues, clinics, websites, and apps. RESULTS: Of 1272 participants, 32% were aware of GetCheckedOnline. Gay identity, regularly testing at an STBBI clinic, being out to one's healthcare provider, attending GBMSM community venues, and frequent social media use were associated with awareness. Among participants who were aware but had not used GetCheckedOnline, knowing GetCheckedOnline users, using social media, not knowing where else to test, and not wanting to see a doctor were associated with intention to use GetCheckedOnline. CONCLUSION: Early promotion of GetCheckedOnline resulted in greater awareness among those connected to GBMSM.

RéSUMé: OBJECTIFS: Évaluer chez les hommes gais, bisexuels et les hommes ayant des relations sexuelles avec des hommes (gbHARSAH) la connaissance de GetCheckedOnline, un service de dépistage en ligne des infections transmissibles sexuellement et par le sang (ITSS), et l'intention d'utiliser ce service. MéTHODE: Deux ans après le lancement du service, une étude transversale a été menée auprès d'hommes gbHARSAH de plus de 18 ans en Colombie-Britannique, au Canada. Les participants ont été recrutés dans les milieux associatifs, les cliniques, sur des sites Web et au moyen d'applications. RéSULTATS: Sur 1 272 participants, 32 % connaissaient GetCheckedOnline. L'identité gaie, le dépistage périodique à une clinique d'ITSS, le fait d'avoir dévoilé son orientation sexuelle à son dispensateur de soins de santé, la fréquentation de milieux associatifs pour hommes gbHARSAH et l'utilisation fréquente des médias sociaux étaient associés à la connaissance du service. Chez les participants qui connaissaient GetCheckedOnline mais qui ne l'avaient pas utilisé, le fait de connaître des utilisateurs de GetCheckedOnline, l'utilisation des médias sociaux, le fait de ne pas savoir où se faire tester ailleurs et le fait de ne pas vouloir voir un médecin étaient associés à l'intention d'utiliser GetCheckedOnline. CONCLUSION: La promotion précoce de GetCheckedOnline a rehaussé la visibilité de ce service dans les milieux en lien avec les hommes gbHARSAH.

False-positive blood cultures: The need for follow-up.

The diagnosis of blood-borne infections in immunocompromised patients is a major challenge for the clinical microbiology laboratory. Isolation of bloodborne pathogens in these patients has profound clinical implications, yet is fraught with technical problems, including the presence of unusual and difficult to isolate pathogens. Coupled with this is the problem of false-positive blood culture signals from automated blood culture systems which further delays the definitive diagnosis. Here, we present a case of an 8-year-old boy with Ph +ve acute lymphoblastic leukaemia who has repeated 'false positive' blood cultures and later grew an uncommon organism.

Designing an electronic blood-borne virus risk alert to improve uptake of testing.

The primary aim of the current study was to test the effect of the presentation design of a test alert system on healthcare workers' (HCWs') decision-making regarding blood-borne virus (BBV) testing. The secondary aim was to determine HCWs' acceptance of the system. An online survey used a within-subjects research design with four design factors as independent variables. The dependent variable was clinical decision. Ten realistic descriptions of hypothetical patients were presented to participants who were asked to decide whether to request BBV testing. The effect of a pre-set course of action to request BBV testing was significant when additional information (cost-effectiveness, date of last BBV test or risk assessment) was not presented, with a 16% increase from 30 to 46% accept decisions. When risk assessment information was presented without a pre-set course of action, the effects of cost-effectiveness (27% increase) and last test date (23% decrease) were significant. The main reason for declining to test was insufficient risk. HCWs' acceptance of the test alert system was high and resistance was low. We make recommendations from the results for the design of a subsequent real-world trial of the test alert system.

Practical approach to method verification in plasma and validation in cerebrospinal fluid under accreditation using a flexible scope in molecular virology: setting up the HIV, HBV and HCV Aptima™ Quant Dx assays.

Background Our laboratory obtained the ISO 15189 accreditation for the plasmatic HIV-1, HBV and HCV viral load (VL) using the m2000 RealTime™ system, which was recently changed for the platform Panther®. Here, we discuss a strategy for performing method validation/verification very quickly. Methods We performed the mandatory (repeatability, internal quality assessment [IQA], measurement uncertainty [MU]) and optional technical verifications for CE/IVD assays using the flexible scope range A. We also performed the mandatory assays for the validation of HIV-1 VL in the cerebrospinal fluid (CSF) using the flexible scope range B. The change was checked by following up on the turnaround time (TAT). Results The coefficient of variation (CV%) for repeatability and IQA complied with the limit of 0.25 log. The MU results ranged from 0.04 to 0.25 log copies or IU/mL. The comparisons of methods showed excellent correlations (R2 = 0.96 for the three parameters) but a delayed centrifugation on HCV VL showed variations of up to 2 log IU/mL. An excellent linearity for HIV-1 in the CSF was obtained from 1.5 to 5 log copies/mL with R2 = 0.99. The TAT increased (84%-98%) in routine usage. Conclusions The three Aptima assays are well suited for routine laboratory use and can be integrated within less than 2 weeks in accordance with flexible scope range A. Our data allows us to confidently perform HIV-1 VL in CSF following flexible scope range B. Finally, we provide an organizational guide for flexible scope management in molecular virology within a short time frame.

Consistent high prevalence of undiagnosed blood-borne virus infection in patients attending large urban emergency departments in England.

Understanding local viral hepatitis and HIV epidemiology is essential if WHO elimination targets are to be achieved. We demonstrate a consistently high prevalence of undiagnosed active infection in urban emergency department attendees in England, with variations in local risk groups crucial to informing targeted testing initiatives.
