This review demonstrates the complex interplay between recreational drug use, high-risk sexual practices and STIs. It identifies the description of adverse mental health outcomes in the chemsex setting, thus highlighting the need for a multidisciplinary approach across specialties in the management of those adversely affected. Finally, it illuminates the need for future research into perceived barriers of those who require access to support services to ensure timely and comprehensive support provision.
BackgroundMobile technology has great potential to improve adherence and treatment outcomes in healthcare settings. However, text messaging and phone calls are unaffordable in many resource-limited areas. This study investigates the use of a no-cost alternative mobile phone technology using missed calls (‘buzzing’) to act as a patient reminder. The use of missed calls as a patient reminder was evaluated for feasibility and effectiveness as an appointment reminder in the follow-up of newly-diagnosed human immunodeficiency virus (HIV) positive patients in an HIV testing and counselling department in rural Swaziland.MethodsThis pilot study uses a before-and-after operational research study design, with all patients with mobile phones being offered the intervention. The primary outcome was the rate of attendance at the HIV testing and counselling department for collection of results in those with mobile phones before and after the introduction of the intervention.ResultsOver two-thirds, 71.8% (459/639), of patients had a mobile phone. All patients with a mobile phone consented to being buzzed. There was no difference in attendance for follow-up at the clinic before and after the intervention was implemented (80.1% versus 83.3%, p = 0.401), or after adjusting for confounding factors (OR 1.13, p = 0.662).ConclusionThis pilot study illustrates that mobile technology may be feasible in rural, resource-poor settings as there are high rates of mobile phone ownership and the intervention had a 100% uptake rate, with positive feedback from staff and patients. In this particular setting, the intervention did not improve attendance rates. However, further research is planned to investigate the impact on adherence to appointments and medications in other settings, such as HIV chronic care follow-up and as part of an enhanced package to improve adherence.
BackgroundMalaria is an important cause of illness and death across endemic regions. Considerable success against malaria has been achieved within the past decade mainly through long-lasting insecticide-treated nets (LLINs). However, elimination of the disease is proving difficult as current control methods do not protect against mosquitoes biting outdoors and when people are active. Repellents may provide a personal protection solution during these times.ObjectivesTo assess the impact of topical repellents, insecticide-treated clothing, and spatial repellents on malaria transmission.Search methodsWe searched the following databases up to 26 June 2017: the Cochrane Infectious Diseases Group Specialized Register; the Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library; MEDLINE; Embase; US AFPMB; CAB Abstracts; and LILACS. We also searched trial registration platforms and conference proceedings; and contacted organizations and companies for ongoing and unpublished trials.Selection criteriaWe included randomized controlled trials (RCTs) and cluster-randomized controlled trials of topical repellents proven to repel mosquitoes; permethrin-treated clothing; and spatial repellents such as mosquito coils. We included trials that investigated the use of repellents with or without LLINs, referred to as insecticide-treated nets.Data collection and analysisTwo review authors independently reviewed trials for inclusion, extracted the data, and assessed the risk of bias. A third review author resolved any discrepancies. We analysed data by conducting meta-analysis and stratified by whether the trials had included LLINs. We combined results from cRCTs with individually RCTs by adjusting for clustering and presented results using forest plots. We used GRADE to assess the certainty of the evidence.Main resultsEight cRCTs and two RCTs met the inclusion criteria. Six trials investigated topical repellents, two trials investigated insecticide-treated clothing, and two trials investigated spatial repellents.Topical repellentsSix RCTS, five of them cluster-randomized, investigated topical repellents involving residents of malaria-endemic regions. Four trials used topical repellents in combination with nets, but two trials undertaken in displaced populations used topical repellents alone. It is unclear if topical repellents can prevent clinical malaria (RR 0.65, 95% CI 0.4 to 1.07, very low certainty evidence) or malaria infection (RR 0.84, 95% CI 0.64 to 1.12, low-certainty evidence) caused by P. falciparum. It is also unclear if there is any protection against clinical cases of P. vivax (RR 1.32, 95% CI 0.99 to 1.76, low-certainty evidence) or incidence of infections (RR 1.07, 95% CI 0.80 to 1.41, low-certainty evidence). Subgroup analysis of trials including insecticide-treated nets did not show a protective effect of topical repellents against malaria. Only two studies did not include insecticide-treated nets, and they measured different outcomes; one reported a protective effect against clinical case...
Working with victims of sex trafficking significantly impacts on the physical and psychological health of staff. Staff working with such vulnerable groups require training and high levels of support to ensure that they are not adversely affected by their work and to ensure that high quality services are maintained. Practices to promote occupational health must be instilled within workplace policy and the organizational culture to limit the impact on psychological and physical health in staff working with vulnerable populations.
BackgroundFinancial issues are major barriers for rural-to-urban migrants accessing tuberculosis (TB) care in China. This paper discusses the effectiveness of providing financial incentives to migrant TB patients (with a focus on poor migrants in one district of Shanghai using treatment completion and default rates), the effect of financial incentives in terms of reducing the TB patient cost, and the incremental cost-effectiveness ratio of the intervention.ResultsNinety and ninety-three migrant TB patients were registered in the intervention and control districts respectively. TB treatment completion rates significantly improved by 11% (from 78% to 89%) in the intervention district, compared with only a 3% increase (from 73% to 76%) in the control district (P = 0.03). Default rates significantly decreased by 11% (from 22% to 11%) in the intervention district, compared with 1% (from 24% to 23%) in the control district (P = 0.03). In the intervention district, the financial subsidy (RMB 1,080/US$170) accounted for 13% of the average patient direct cost (RMB 8,416/US$1,332). Each percent increase in treatment completion costs required an additional RMB 6,550 (US$1,301) and each percent reduction in defaults costs required an additional RMB 5,240 (US$825) in the intervention district.ConclusionsOverall, financial incentives proved to be effective in improving treatment completion and reducing default rates among migrant TB patients in Shanghai. The results suggest that financial incentives can be effectively utilized as a strategy to enhance case management among migrant TB patients in large cities in China, and this strategy may be applicable to similar international settings.
BackgroundThe UK Department of Health recommends annual influenza vaccination for healthcare workers, but uptake remains low. For staff, there is uncertainty about the rationale for vaccination and evidence underpinning the recommendation.ObjectivesTo clarify the rationale, and evidence base, for influenza vaccination of healthcare workers from the occupational health, employer and patient safety perspectives.DesignSystematic appraisal of published systematic reviews.ResultsThe quality of the 11 included reviews was variable; some included exactly the same trials but made conflicting recommendations. 3 reviews assessed vaccine effects in healthcare workers and found 1 trial reporting a vaccine efficacy (VE) of 88%. 6 reviews assessed vaccine effects in healthy adults, and VE was consistent with a median of 62% (95% CI 56 to 67). 2 reviews assessed effects on working days lost in healthcare workers (3 trials), and 3 reported effects in healthy adults (4 trials). The meta-analyses presented by the most recent reviews do not reach standard levels of statistical significance, but may be misleading as individual trials suggest benefit with wide variation in size of effect. The 2013 Cochrane review reported absolute effects close to 0 for laboratory-confirmed influenza, and hospitalisation for patients, but excluded data on clinically suspected influenza and all-cause mortality, which had shown potentially important effects in previous editions. A more recent systematic review reports these effects as a 42% reduction in clinically suspected influenza (95% CI 27 to 54) and a 29% reduction in all-cause mortality (95% CI 15 to 41).ConclusionsThe evidence for employer and patient safety benefits of influenza vaccination is not straightforward and has been interpreted differently by different systematic review authors. Future uptake of influenza vaccination among healthcare workers may benefit from a fully transparent guideline process by a panel representing all relevant stakeholders, which clearly communicates the underlying rationale, evidence base and judgements made.
Reports of sexualised drug taking (chemsex) have increased significantly in recent years. There is currently limited intelligence on chemsex outside of London. An anonymous survey was promoted via several sources including voluntary services and a sexual health clinic in order to establish the risks associated with chemsex, and how support services can best be tailored to meet the needs of those in Greater Manchester, UK. Quantitative and qualitative data were collected on demographics, drug use, sexual practices and barriers and facilitators to accessing support. Fifty-two men who have sex with men completed the online survey. Thirty-nine (75%) were HIV-positive and 11 (21%) were hepatitis C virus (HCV) positive, all of whom were HIV/HCV co-infected. The most commonly used drugs were mephedrone (81%) and gamma hydroxybutyrate/gamma butyrolactone (79%). Nineteen (37%) reported ever injecting drugs. High-risk sexual practices were reported by respondents. Barriers to accessing support included a fear of being recognised. Findings demonstrate those engaging in chemsex are participating in a number of high-risk sexual practices, taking substances with significant risks and administering these substances in potentially high-risk ways. Results demonstrate the need for promotion of existing services, with key areas to target where chemsex sessions are most commonly arranged. Results may be useful in other metropolitan cities, both for commissioning and tailoring of chemsex support services.
