Incidence of sexually transmitted infections and association with behavioural factors: Time-to-event analysis of a large pre-exposure prophylaxis (PrEP) cohort.

OBJECTIVES: Our objective was to obtain long-term data on the incidence of sexually transmitted infections (STIs) and their association with behavioural factors after widespread pre-exposure prophylaxis (PrEP) implementation. METHODS: This was a time-to-event analysis of a national PrEP cohort in Switzerland (SwissPrEPared study). Participants were people without HIV interested in taking PrEP with at least two STI screening visits. Primary outcomes were incidence rate of gonorrhoea, chlamydia, and syphilis. The association between behavioural factors and STI diagnosis was expressed using hazard ratios. We adjusted for testing frequency and calendar year. RESULTS: This analysis included 3907 participants enrolled between April 2019 and April 2022, yielding 3815.7 person-years of follow-up for gonorrhoea (15 134 screenings), 3802.5 for chlamydia (15 141 screenings), and 3858.6 for syphilis (15 001 screenings). The median age was 39 years (interquartile range [IQR] 32-47), 93.8% (n = 3664) identified as men who have sex with men (MSM). The incidence was 22.8 (95% confidence interval [CI] 21.3-24.4) per 100 person-years for gonorrhoea, 26.3 (95% CI 24.7-28.0) for chlamydia, and 4.4 (95% CI 3.8-5.1) for syphilis. Yearly incidence rates decreased between 2019 (all bacterial STIs: 81.6; 95% CI 59.1-109.9) and 2022 (all bacterial STIs: 49.8; 95% CI 44.6-55.3). Participants reporting chemsex substance use were at higher risk of incident STIs, as were those reporting multiple sexual partners. Younger age was associated with a higher risk of gonorrhoea and chlamydia. CONCLUSIONS: Incidence rates of bacterial STIs decreased over time. Young MSM, those with multiple partners, and those using chemsex substances were at increased risk of STIs.

Exploring group differences in the response to a sexual risk reduction intervention to prevent hepatitis C virus reinfection in HIV-infected MSM: a mixed-methods study.

To prevent hepatitis C virus (HCV) reinfection, within the Swiss HCVree Trial, a preventive risk reduction intervention was implemented alongside curative treatment. Formative qualitative research identified three response patterns to the intervention. This mixed-methods study's aim was to cross-validate group differences in (a) the content of sexual risk reduction goals set during intervention and (b) the extent of their behavioural change in condomless anal intercourse with non-steady partners (nsCAI), sexualised and intravenous drug use at start and six-month post-intervention. Qualitative thematic analysis was used to summarise goal setting domains. Quantitative descriptive analysis was used to evaluate group differences based on assumptions of the group descriptions. Results largely confirmed assumptions on inter-group response differences in goal setting and behaviour: as expected group 1 Avoid risks showed the lowest HCV risk profile with changes in nsCAI. Group 2 Minimize-risks and Group 3 Accept-risks showed unchanged nsCAI. Group 3 had the highest HCV risk profile. Differences in their goal preferences (1: condom use; 2 reduction blood exposure; 3 safer dating) highlight diversity in attitudes to behavioural change. Our results improve understanding of variability in intervention responses such as changes in attitudes and behaviour. This provides evidence for intervention tailoring and outcome measurement.

Setting new priorities for nursing research: The updated Swiss Nursing Research Agenda-a systematic, participative approach.

AIM: To identify current key areas for nursing research in Switzerland, we revised the Swiss Research Agenda for Nursing (SRAN) initially published in 2008. BACKGROUND: By developing a research agenda, nursing researchers internationally prioritize and cluster relevant topics within the research community. The process should be collaborative and systematic to provide credible information for decisionmakers in health care research, policy, and practice. SOURCES OF EVIDENCE: After a participative, systematic, and critical evaluation within and outside of the Swiss Association for Nursing Science, the updated SRAN 2019-2029 defines four research priorities (new models of care, nursing care interventions, work and care environment, and quality of care and patient safety) and four transversal themes (organization of research, research methodologies, research in health care policy and public health perspectives). CONCLUSION: Adding to other national nursing research agendas, the categories are organized in a framework of key research priorities and transversal themes. They relate to the importance of global and local foci of research as well as challenges in health care services and policy systems. The agenda is an important prerequisite for enhancing the influence of nursing research in Switzerland and provides guidance for the next decade. IMPLICATIONS FOR NURSING PRACTICE: The revised agenda ensures that research projects target key knowledge gaps and the discipline's core questions in respective countries. IMPLICATIONS FOR HEALTH POLICY: Nursing research should inform and influence health policy on all institutional and political levels. Therefore, the integration of public health perspectives in research is one of the most important new aspects of SRAN 2019-2029.

Triggers of Change in Sexual Behavior Among People With HIV: The Swiss U U Statement and COVID-19 Compared.

We assessed changes in sexual behavior among people with human immunodeficiency virus (HIV) over 20 years. Condom use with stable partners steadily declined from over 90 to 29 since the Swiss U U statement, with similar trajectories between men who have sex with men (MSM) and heterosexuals. Occasional partnership remained higher among MSM compared to heterosexuals even during coronavirus disease 2019 (COVID-19) social distancing.

Mapping advanced practice nurses' scope of practice, satisfaction, and drivers of role performance.

Background: Advanced Practice Nurse (APN) roles in Switzerland include Clinical Nurse Specialist (CNS), Nurse Practitioner (NP) and blended roles. The variety contributes to unclear profiles and scope of practice. Aim: To describe a) the performance of APN tasks according to Hamric's competencies, b) job satisfaction, and c) barriers and facilitators to role performance. Methods: Nationwide cross-sectional survey among clinically working APNs. Inclusion criteria: academic degree, role with advanced nursing competency. Analysis of quantitative and qualitative data using inferential statistics and content analysis. Results: Of the 222 APNs, 49% (n = 108) described themselves as CNSs, 37% (n = 81) as working in a blended role, and 15% (n = 33) as NP. APNs provided the greatest proportion of their tasks in the competency direct clinical practice and the least in ethical decision-making. Group comparisons between roles revealed significant differences in the competencies: direct clinical practice, guidance and coaching, leadership, and evidence-based practice. Job satisfaction was high (76%, n = 165), most often described by the category work content/role (e.g., defined scope of practice). The most frequent barrier to role performance was the category scope of practice (e.g., unclear responsibilities); the most frequent facilitator was the category professional recognition (e.g., respect). Conclusion: The study highlights current APN scope of practice and can support the advancement of the role through clinical practice, educational institutions, and research.

Validation of the newly developed Advanced Practice Nurse Task Questionnaire: A national survey.

AIM: To describe psychometric validation of the newly developed Advanced Practice Nurse Task Questionnaire. DESIGN: Cross-sectional quantitative study. METHODS: The development of the questionnaire followed an adapted version of the seven steps described in the guide by the Association for Medical Education in Europe. A nationwide online survey tested the construct and structural validity and internal consistency using an exploratory factor analysis, Cronbach's alpha coefficient and a Kruskal-Wallis test to compare the hypotheses. RESULTS: We received 222 questionnaires between January and September 2020. The factor analysis produced a seven-factor solution as suggested in Hamric's model. However, not all item loadings aligned with the framework's competencies. Cronbach's alpha of factors ranged between .795 and .879. The analysis confirmed the construct validity of the Advanced Practice Nurse Task Questionnaire. The tool was able to discriminate the competencies of guidance and coaching, direct clinical practice and leadership across the three advanced practice nurse roles clinical nurse specialist, nurse practitioner or blended role. CONCLUSION: A precise assessment of advanced practice nurse tasks is crucial in clinical practice and in research as it may be a basis for further refinement, implementation and evaluation of roles. IMPACT: The Advanced Practice Nurse Task Questionnaire is the first valid tool to assess tasks according to Hamric's model of competencies independently of the role or the setting. Additionally, it distinguishes the most common advanced practice nurse roles according to the degree of tasks in direct clinical practice and leadership. The tool may be applied in various countries, independent of the degree of implementation and understanding of advanced nursing practice. REPORTING METHOD: The STARD 2015 guideline was used to report the study. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

[Toward a safe home: Experiencing the transition to an outpatient setting with home mechanical ventilation. A thematic analysis]. / Auf dem Weg in ein sicheres Daheim: Erleben des Übergangs in ein ambulantes Setting mit Heimbeatmung.

Toward a safe home: Experiencing the transition to an outpatient setting with home mechanical ventilation. A thematic analysis Abstract. Background: With the progress in medical options, the need for home mechanical ventilation increases. The transition from long-term ventilation in an institution to home mechanical ventilation in an outpatient setting is a difficult phase in terms of setting up the network of care, coordination of care for those with the ventilatory insufficiency and the financing. Aim: The study describes how patients with ventilatory insufficiency and family caregivers experience the transition from an institution to an ambulatory setting with invasive or non-invasive home mechanical ventilation. Methods: A qualitative research design with a social-constructivist approach was adopted using thematic analysis according to Braun and Clarke. We included seven German-speaking patients (≥ 18 years old) with ventilatory insufficiency and home mechanical ventilation (> 6 h/day) from the German part of Switzerland, with discharge from an institution to home, and five family caregivers who care for patients with the described criteria. Results: The institution was seen as a safe place. Affected persons and their family caregivers had to create a safe environment at home. Three themes were formed inductively: To gradually build trust with each other, to become experts as family caregivers, to align their own network with the new care needs.Conclusions: The transition home succeeds in the interplay of gaining trust, building expertise, and creating sustainable networks. Professionals can use this knowledge to provide targeted support to patients with home mechanical ventilation and their family caregivers.

Assessing the drivers of syphilis among men who have sex with men in Switzerland reveals a key impact of screening frequency: A modelling study.

Over the last decade, syphilis diagnoses among men-who-have-sex-with-men (MSM) have strongly increased in Europe. Understanding the drivers of the ongoing epidemic may aid to curb transmissions. In order to identify the drivers of syphilis transmission in MSM in Switzerland between 2006 and 2017 as well as the effect of potential interventions, we set up an epidemiological model stratified by syphilis stage, HIV-diagnosis, and behavioral factors to account for syphilis infectiousness and risk for transmission. In the main model, we used 'reported non-steady partners' (nsP) as the main proxy for sexual risk. We parameterized the model using data from the Swiss HIV Cohort Study, Swiss Voluntary Counselling and Testing center, cross-sectional surveys among the Swiss MSM population, and published syphilis notifications from the Federal Office of Public Health. The main model reproduced the increase in syphilis diagnoses from 168 cases in 2006 to 418 cases in 2017. It estimated that between 2006 and 2017, MSM with HIV diagnosis had 45.9 times the median syphilis incidence of MSM without HIV diagnosis. Defining risk as condomless anal intercourse with nsP decreased model accuracy (sum of squared weighted residuals, 378.8 vs. 148.3). Counterfactual scenarios suggested that increasing screening of MSM without HIV diagnosis and with nsP from once every two years to twice per year may reduce syphilis incidence (at most 12.8% reduction by 2017). Whereas, increasing screening among MSM with HIV diagnosis and with nsP from once per year to twice per year may substantially reduce syphilis incidence over time (at least 63.5% reduction by 2017). The model suggests that reporting nsP regardless of condom use is suitable for risk stratification when modelling syphilis transmission. More frequent screening of MSM with HIV diagnosis, particularly those with nsP may aid to curb syphilis transmission.

Implementation of a complex intervention to reduce hospitalizations from nursing homes: a mixed-method evaluation of implementation processes and outcomes.

BACKGROUND | OBJECTIVE: To evaluate the implementation of three intervention elements to reduce hospitalizations in nursing home residents. DESIGN: Convergent mixed-method design within a hybrid type-2 effectiveness-implementation study. SETTING: Eleven nursing homes in the German-speaking region of Switzerland. PARTICIPANTS: Quantitative data were collected from 573 care workers; qualitative data were collected from 108 care workers and the leadership from 11 nursing homes. INTERVENTION: Three intervention elements targeting care workers were implemented to reduce unplanned hospitalizations: (1) the STOP&WATCH instrument for early recognition of changes in resident condition; (2) the ISBAR instrument for structured communication; and (3) specially-trained INTERCARE nurses providing on-site geriatric support. Multifaceted implementation strategies focusing both on the overall nursing home organization and on the care workers were used. METHODS: The quantitative part comprised surveys of care workers six- and twelve-months post-intervention. The intervention's acceptability, feasibility and uptake were assessed using validated and self-developed scales. Qualitative data were collected in 22 focus groups with care workers, then analyzed using thematic analysis methodology. Data on implementation processes were collected during implementation meetings with nursing home leadership and were analyzed via content analysis. Findings were integrated using a complementary approach. RESULTS: The ISBAR instrument and the INTERCARE nurse role were considered acceptable, feasible, and taken up by > 70% of care workers. The STOP&WATCH instrument showed the lowest acceptance (mean: 68%), ranging from 24 to 100% across eleven nursing homes. A combination of factors, including the amount of information received, the amount of support provided in daily practice, the users' perceived ease of using the intervention and its adaptations, and the intervention's usefulness, appeared to influence the implementation's success. Two exemplary nursing homes illustrated context-specific implementation processes that serve as either barriers or facilitators to implementation. CONCLUSIONS: Our findings suggest that, alongside the provision of information shortly before intervention start, constant daily support is crucial for implementation success. Ideally, this support is provided by designated and trained individuals who oversee implementation at the organizational and unit levels. Leaders who seek to implement interventions in nursing homes should consider their complexity and their consequences for workflow to optimize implementation processes accordingly. TRIAL REGISTRATION: This study was registered at clinicaltrials.gov ( NCT03590470 ) on the 18/06/2018.

Health economic evaluation of a nurse-led care model from the nursing home perspective focusing on residents' hospitalisations.

BACKGROUND: Health economic evaluations of the implementation of evidence-based interventions (EBIs) into practice provide vital information but are rarely conducted. We evaluated the health economic impact associated with implementation and intervention of the INTERCARE model-an EBI to reduce hospitalisations of nursing home (NH) residents-compared to usual NH care. METHODS: The INTERCARE model was conducted in 11 NHs in Switzerland. It was implemented as a hybrid type 2 effectiveness-implementation study with a multi-centre non-randomised stepped-wedge design. To isolate the implementation strategies' costs, time and other resources from the NHs' perspective, we applied time-driven activity-based costing. To define its intervention costs, time and other resources, we considered intervention-relevant expenditures, particularly the work of the INTERCARE nurse-a core INTERCARE element. Further, the costs and revenues from the hotel and nursing services were analysed to calculate the NHs' losses and savings per resident hospitalisation. Finally, alongside our cost-effectiveness analysis (CEA), a sensitivity analysis focused on the intervention's effectiveness-i.e., regarding reduction of the hospitalisation rate-relative to the INTERCARE costs. All economic variables and CEA were assessed from the NHs' perspective. RESULTS: Implementation strategy costs and time consumption per bed averaged 685CHF and 9.35 h respectively, with possibilities to adjust material and human resources to each NH's needs. Average yearly intervention costs for the INTERCARE nurse salary per bed were 939CHF with an average of 1.4 INTERCARE nurses per 100 beds and an average employment rate of 76% of full-time equivalent per nurse. Resident hospitalisation represented a total average loss of 52% of NH revenues, but negligible cost savings. The incremental cost-effectiveness ratio of the INTERCARE model compared to usual care was 22'595CHF per avoided hospitalisation. As expected, the most influential sensitivity analysis variable regarding the CEA was the pre- to post-INTERCARE change in hospitalisation rate. CONCLUSIONS: As initial health-economic evidence, these results indicate that the INTERCARE model was more costly but also more effective compared to usual care in participating Swiss German NHs. Further implementation and evaluation of this model in randomised controlled studies are planned to build stronger evidential support for its clinical and economic effectiveness.

A Treatment-as-Prevention Trial to Eliminate Hepatitis C Among Men Who Have Sex With Men Living With Human Immunodeficiency Virus (HIV) in the Swiss HIV Cohort Study.

BACKGROUND: In 2016, the World Health Organization (WHO) introduced global targets for the elimination of hepatitis C virus (HCV) by 2030. We conducted a nationwide HCV micro-elimination program among men who have sex with men (MSM) living with human immunodeficiency virus (HIV) from the Swiss HIV Cohort Study (SHCS) to test whether the WHO goals are achievable in this population. METHODS: During phase A (10/2015-06/2016), we performed a population-based and systematic screening for HCV-RNA among MSM from the SHCS. During phase B (06/2016-02/2017) we offered treatment with HCV direct-acting antiviral (DAA) agents to MSM identified with a replicating HCV infection. During phase C (03/2017-11/2017), we offered rescreening to all MSM for HCV-RNA and initiated DAA treatment in MSM with replicating infections. RESULTS: We screened 3715/4640 (80%) MSM and identified 177 with replicating HCV infections (4.8%); 150 (85%) of whom started DAA treatment and 149 (99.3%) were cured. We rescreened 2930/3538 (83%) MSM with a prior negative HCV-RNA and identified 13 (0.4%) with a new HCV infection. At the end of the micro-elimination program, 176/190 MSM (93%) were cured, and the HCV incidence rate declined from .53 per 100 patient-years (95% CI, .35-.83) prior to the intervention to .12 (95% CI, .03-.49) by the end of 2019. CONCLUSIONS: A systematic, population-based HCV micro-elimination program among MSM living with HIV was feasible and resulted in a strong decline in HCV incidence and prevalence. Our study can serve as a model for other countries aiming to achieve the WHO HCV elimination targets. CLINICAL TRIALS REGISTRATION: NCT02785666.

Response to a sexual risk reduction intervention provided in combination with hepatitis C treatment by HIV/HCV co-infected men who have sex with men: a reflexive thematic analysis.

BACKGROUND: Hepatitis C virus reinfections in HIV-positive men-who-have-sex-with-men (MSM) challenge the effectiveness of antiviral treatment. To fight this problem, an adapted sexual risk reduction intervention was implemented within a hepatitis C treatment trial. Following this, the current study had two aims and describes 1) how the program was received by participants; and 2) their responses to the program regarding sexual risk taking. Based on the participants' input, we hoped to judge the intervention's potential for scale-up. METHODS: Seventeen participants who received the sexual risk reduction intervention in addition to hepatitis C treatment were recruited for semi-structured interviews six to 12 months post-intervention. We evaluated the responses via reflexive thematic analysis and applied the concept of sense-making. RESULTS: Giving hepatitis C a place and living without it again illustrates how participants received the program and how their experiences were altered by the impact of sense-making. Based on their responses, we allocated participants to three groups: 1. Avoid risks: get rid of hepatitis C for life. For these men, hepatitis C remained a life-threatening disease: they actively modified their risk behavior and felt supported by the intervention in maintaining their behavioral changes. 2. Minimize risks: live as long as possible without hepatitis C. In contrast to group 1, these men saw hepatitis C as a manageable disease. The intervention facilitated reflection on risks and how to develop behavioral changes that suited them individually. 3. Accept risks; live with the risk of hepatitis C. These men perceived behavioral changes as much more difficult than "easy" medical treatment. They expected to either undergo repeated rounds of treatment or stay HCV re-infected. CONCLUSION: These results illustrate the diversity of men's responses and their decisions regarding sexual risk behavior after participating in a combination of antiviral treatment and a sexual risk reduction intervention. Two major aspects were identified: 1) Teachable moments, particularly at the time of diagnosis/treatment, could offer an opportunity to develop openness for behavioral change; 2) adapting sexual risk reduction interventions to sense-making patterns could help to improve its effectiveness. Support for reducing infection risk and raising awareness of preventative measures are additional benefits. TRIAL REGISTRATION: Clinical Trial Number: NCT02785666 , 30.05.2016.

The challenge of interprofessional collaboration in emergency department team triage - An interpretive description.

AIMS: To explore emergency nurses' and physicians' experience of collaboration and collective decision-making when triaging older Emergency Department patients within the interprofessional team triage system. DESIGN: Qualitative. METHODS: Semi-structured interviews were conducted with seven nurses and five physicians. Transcripts were analysed via Interpretive Description between September 2016-May 2017. RESULTS: 'Negotiating collaboration' was developed as the main theme. Three subthemes influenced the negotiation process: Participants described divergent opinions on how an optimal triage system should work ('preferences for triage systems'); they had conflicting perceptions of each profession's role ('role perceptions'); and they expressed different coping strategies regarding 'perceived time pressure'. The compatibility of participants' views on these sub-themes determined whether the nurse and physician were able to successfully negotiate their collaboration. These themes became more evident when the team triaged older ED patients. CONCLUSION: Improving interprofessional team triage requires working with the involved nurses' and physicians' values and beliefs. The strengths of both professions need to be considered and a flexible approach to collaboration established according to the patients' situations. IMPACT: Emergency Department leaders need to consider nurses' and physicians' values and beliefs to promote interprofessional collaboration in team triage.

[Experiences of Advanced Practice Nurses with a clinical postgraduate education program in the context of their professional development]. / Erfahrungen von Advanced Practice Nurses mit einem klinischen Weiterbildungsstudiengang im Kontext ihrer beruflichen Entwicklung.

Experiences of Advanced Practice Nurses with a clinical postgraduate education program in the context of their professional development Abstract. Background: The Diploma of Advanced Studies in Advanced Nursing Practice (DAS ANP-plus), which has been offered at the University of Basel since 2012, is a clinically oriented postgraduate education program for the still poorly established professional group of the Advanced Practice Nurse (APN). The acquisition of clinical skills plays a central role in the professional biography and for the APN's work in patient healthcare. Aim: The qualitative study aims to explore the experiences of APNs during and after a clinically oriented postgraduate education program in Switzerland and what significant changes they experienced in their professional practice. Methods: Reflexive thematic analysis with a constructivist orientation was used. With fourteen APNs, guided interviews were conducted and analyzed considering the professional biography. Results: "Pursuing the vision for a better care" is the constitutive theme. The graduates all seem to be driven by a strong vision: from striving to know more, to implementing the concept of Advanced Nursing Practice, to initiating changes in the healthcare system. The vision is shaped by three themes: "the challenges of gaining a foothold as an APN" before the program, "gaining security by strengthening clinical skills" during the program and on longer terms "breaking new ground in the healthcare system with allies". Conclusions: The DAS ANP-plus increases the clinical skills of APNs within clinical supervision plays an important role.

Clusters of Sexual Behavior in Human Immunodeficiency Virus-positive Men Who Have Sex With Men Reveal Highly Dissimilar Time Trends.

BACKGROUND: Separately addressing specific groups of people who share patterns of behavioral change might increase the impact of behavioral interventions to prevent transmission of sexually transmitted infections. We propose a method based on machine learning to assist the identification of such groups among men who have sex with men (MSM). METHODS: By means of unsupervised learning, we inferred "behavioral clusters" based on the recognition of similarities and differences in longitudinal patterns of condomless anal intercourse with nonsteady partners (nsCAI) in the HIV Cohort Study over the last 18 years. We then used supervised learning to investigate whether sociodemographic variables could predict cluster membership. RESULTS: We identified 4 behavioral clusters. The largest behavioral cluster (cluster 1) contained 53% of the study population and displayed the most stable behavior. Cluster 3 (17% of the study population) displayed consistently increasing nsCAI. Sociodemographic variables were predictive for both of these clusters. The other 2 clusters displayed more drastic changes: nsCAI frequency in cluster 2 (20% of the study population) was initially similar to that in cluster 3 but accelerated in 2010. Cluster 4 (10% of the study population) had significantly lower estimates of nsCAI than all other clusters until 2017, when it increased drastically, reaching 85% by the end of the study period. CONCLUSIONS: We identified highly dissimilar behavioral patterns across behavioral clusters, including drastic, atypical changes. The patterns suggest that the overall increase in the frequency of nsCAI is largely attributable to 2 clusters, accounting for a third of the population.

High Cure Rates With Grazoprevir-Elbasvir With or Without Ribavirin Guided by Genotypic Resistance Testing Among Human Immunodeficiency Virus/Hepatitis C Virus-coinfected Men Who Have Sex With Men.

Background: This study was performed to investigate the efficacy and safety of grazoprevir-elbasvir guided by baseline resistance-associated substitutions (RASs) in the Swiss HCVree Trial. Methods: We performed hepatitis C virus (HCV) RNA screening among all men who have sex with men (MSM) enrolled in the Swiss HIV Cohort Study. Individuals with replicating HCV genotype 1 or 4 infection were eligible for grazoprevir-elbasvir treatment. Genotype 1a-infected individuals with baseline RASs and genotype 4-infected individuals with prior failure of HCV treatment received 16 weeks of grazoprevir-elbasvir combined with ribavirin. All other individuals received 12 weeks of grazoprevir-elbasvir alone. Patients reporting unprotected sex with occasional partners were offered a HCV risk reduction-oriented behavioral intervention. Results: We screened 3722 MSM and identified 177 (4.8%) with replicating infection. A total of 122 individuals (3.3%) were eligible for study treatment. Six of 76 patients infected with genotype 1a (7.3%) harbored baseline RASs. Sustained virological response after 12 weeks of follow-up was achieved in 121 patients (99%), including all with genotype 1a infection. Overall, 8 serious adverse events occurred, none of which was related to the study drug. Seventy-five percent of eligible MSM participated in the risk counseling program. Conclusions: Grazoprevir-elbasvir for 12 or 16 weeks, with or without ribavirin, achieved high cure rates and had an excellent safety profile. Unique to other studies, the treatment duration was guided by the presence of baseline RASs among genotype 1a-infected individuals, and the treatment phase was accompanied by an HCV risk reduction-oriented behavioral intervention. This successful population-wide treatment approach lays the groundwork to achieve HCV elimination in coinfected MSM. Clinical Trials Registration: NCT02785666.

Screening HIV-positive men who have sex with men for hepatitis C re-infection risk: is a single question on condom-use enough? A sensitivity analysis.

BACKGROUND: Hepatitis C virus (HCV) is common in men who have sex with men (MSM) with HIV. The Swiss HCVree Trial targeted a micro-elimination by using a treat and counsel strategy. Self-reported condomless anal intercourse with non-steady partners was used as the selection criterion for participation in a counselling intervention designed to prevent HCV re-infection. The purpose of this study was to assess the ability of this criterion to identify men who engaged in other sexual risk behaviours associated with HCV re-infection. METHODS: Men who disclosed their sexual and drug- use behaviours during the prior 6 months, at study baseline, were included in the current study. Using a descriptive comparative study design, we explored self-reported sexual and drug-use risk behaviours, compared the odds of reporting each behaviour in men who reported and denied condomless anal intercourse with non-steady partners during the prior year and calculated the sensitivity/specificity (95% CI) of the screening question in relation to the other at-risk behaviours. RESULTS: Seventy-two (61%) of the 118 men meeting eligibity criteria reported condomless anal intercourse with non-steady partners during the prior year. Many also engaged in other potential HCV transmission risk behaviours, e.g., 52 (44%) had used drugs. In participants disclosing drug use, 44 (37%) reported sexualised drug use and 17 (14%) injected drugs. Unadjusted odds ratios (95% CI) for two well-known risk behaviours were 2.02 (0.80, 5.62) for fisting and 5.66 (1.49, 37.12) for injecting drug use. The odds ratio for sexualised drug use - a potential mediator for increased sexual risk taking - was 5.90 (2.44, 16.05). Condomless anal intercourse with non-steady partners showed varying sensitivity in relation to the other risk behaviours examined (66.7-88.2%). CONCLUSIONS: Although condomless anal intercourse with non-steady partners was fairly sensitive in detecting other HCV relevant risk behaviours, using it as the only screening criterion could lead to missing a proportion of HIV-positive men at risk for HCV re-infection due to other behaviours. This work also points to the importance of providing access to behavioral interventions addressing other sexual and drug use practices as part of HCV treatment.

Developing a rare disease chronic care model: Management of systemic sclerosis (MANOSS) study protocol.

AIM: The aim of the management of systemic sclerosis (MANOSS) study described in this protocol is to develop a chronic care model, based on a contextual analysis and stakeholder involvement, for patients living with the rare disease systemic sclerosis (SSc) in Switzerland. DESIGN: Applying an implementation science approach, this study starts with an explanatory sequential mixed method study for contextual analysis, followed by broad stakeholder involvement for model development and a Delphi study to reach consensus. METHODS: First, a quantitative cross-sectional survey with patients and healthcare professionals (HPs) will be conducted to identify current practice patterns of chronic illness management and technology readiness. Second, qualitative interviews with patients, family members and HPs will be performed to gain a deeper understanding of care needs identified in the quantitative survey. Third, a model of care will be co-created with input from patients, HPs and other experts. The eHealth enhanced Chronic Care Model will serve as a guiding framework. The new model and corresponding outcome parameters will be refined using a Delphi-study approach to reach consensus on a testable model of care for persons living with SSc. The protocol has received research ethics committee approval in September 2018 by the Swiss Ethics Committee. DISCUSSION: The MANOSS study's participatory approach is essential for contextual fit of the model for patients with SSc in this setting. Subsequent feasibility testing and implementation are planned to evaluate the model's value in relation to health disparities faced by this patient population. IMPACT: Patients living with this rare disease lack access to coordinated, specialized care and self-management support from qualified HPs. Reengineering of current care, with consideration for technological opportunities, is warranted to meet patients' and families' needs.

Incidence of hepatitis C in HIV positive and negative men who have sex with men 2000-2016: a systematic review and meta-analysis.

BACKGROUND: There is a need for systematic reviews and meta-analyses to synthesize the epidemiology, and the riskfactors for hepatitis C virus (HCV) among HIV-coinfected and HIV negative men who have sex with men (MSM). METHODS: A meta-analysis of 28 studies was carried out by pooling HCV incidence data of HIV-coinfected and HIV negative MSM. Differences in incidence outcome depending on the prospective or retrospective nature of the individual studies were investigated. RESULTS: The pooled incidence of HCV in MSM was 6.3 per 1000 person-years (95% CI 5.0-7.5). The overall estimated incidence was 19-fold higher in HIV positive compared to HIV negative MSM living in resource-rich countries. This result was confirmed when the analysis was restricted to high-quality studies. Factors associated with an increased risk for incident HCV included behavioural factors (sexual risk behaviour and recreational drug use) as well as biological characteristics (HIV coinfection and a recent history of syphilis). CONCLUSION: In conclusion, incident HCV predominantly affects HIV positive MSM. The incidence rate varied largely between studies, factors such as study design might play an important role.

High prevalence of physical inactivity among patients from the Swiss HIV Cohort Study.

Physical activity (PA) can improve cardiorespiratory status, strength, body composition and quality of life for patients infected with HIV. Evidence from HIV-uninfected populations also shows that PA is associated with a lower risk of mortality, primarily death due to cardiovascular causes. There is, however, a lack of data on how physically active HIV-infected patients are. In this study, we assessed levels of self-reported PA over time in patients enrolled in the Swiss HIV Cohort Study, a large multicentre prospective observational cohort study. We included a total of 10,540 patients who completed at least one report of PA between December 2009 and November 2014 during routine clinical follow-up (scheduled every 6 months). In the first year after December 2009 there was a higher rate of non-response so these data are of a lesser reliability. Over the next four years, the percentage of patients reporting no free-time PA at all declined from 49% to 44%. In contrast, in two "Sport Switzerland" surveys of the general population in 2008 and 2014, the percentage of individuals reporting no sports activities at all was considerably lower and relatively stable over time (27% in 2008; 26% in 2014). In our analysis, the percentage of patients reporting sedentary activity at work increased from 23% to 26% over the four years. Subgroup findings suggest differences between women and men and between patients classified by their age, stage of infection and CD4 cell count. Integrating PA counselling into the routine care of HIV-infected patients and promoting PA among this population has the potential to improve the general state of health and quality of life for HIV-infected patients and reduce their risk of cardiovascular disease.
