Summary: Syphilis is a persistent public health issue in many low-income countries that have limited capacity for testing, which traditionally relies on a sensitive non-treponemal test and then a specific treponemal test. However, the development of a new rapid treponemal test provides an opportunity to scale up syphilis screening in many settings where traditional tests are unavailable. This systematic review of immunochromatographic strip (ICS) syphilis tests describes the sensitivity and specificity in two important clinical settings: sexually transmitted infection (STI) clinics and antenatal clinics. Clinical data from more than 22 000 whole blood, plasma, or fingerstick ICS tests obtained at STI or antenatal clinics were retrieved from 15 studies. ICS syphilis tests have a high sensitivity (median 0·86, interquartile range 0·75–0·94) and a higher specificity (0·99, 0·98–0·99), both comparable with non-treponemal screening test characteristics. Further research evaluating ICS syphilis tests among primary syphilis cases and among patients infected with HIV will be essential for the effective roll-out of syphilis screening programmes.

Background: Chinese men who have sex with men (MSM) rarely receive gonorrhoea and chlamydia testing. The purpose of this pilot study was to evaluate a pay-it-forward strategy to increase uptake of gonorrhoea and chlamydia testing among MSM.Methods: We performed a quasi-experimental pragmatic study to compare a pay-it-forward model with standard of care at two HIV testing sites for MSM in Guangzhou, China: an STD clinic for MSM and a local MSM community-based organisation. All men who arrived at the STD clinic or the community-based organisation were invited to participate. In the pay-it-forward programme, men were offered free gonorrhoea and chlamydia testing and given the option of donating money toward testing for future participants. In the standard-of-care group, men were offered gonorrhoea and chlamydia testing at the standard patient price of ¥150 (about US$21·50). The pay-it-forward programme was implemented for 3 months, after which both sites switched to standard of care offering dual testing for 3 months. The primary outcome for this study was uptake of dual gonorrhoea and chlamydia testing, which we compared using χ2 test and logistic regression, reported as crude odds ratios (cOR) and adjusted odds ratios (aOR), by adjusting for nationality, marital status, income, and site of testing.Findings: The pay-it-forward programme took place from Dec 2, 2017, to Feb 3, 2018, and the standard-of-care control took place from March 11, 2018, to May 1, 2018. 408 men were included in this study. 203 men were offered pay-it-forward, and 205 were offered standard of care. Overall, 109 (54%) of 203 men in the pay-it-forward group and 12 (6%) of 205 men in the standard-of-care group received gonorrhoea and chlamydia testing (cOR 18·65, 9·78-35·54; p<0·0001; aOR 19·73, 95% CI 10·02-38·85; p<0·0001). Of all 121 men who tested, this was the first gonorrhoea test for 97 (80%) men and the first chlamydia test for 104 (86%) men. Five (4%) of these 121 men were diagnosed with gonorrhoea and 15 (12%) were diagnosed with chlamydia. 97 (89%) of 109 men who received testing in the pay-it-forward group donated some money toward testing for future participants.Interpretation: Pay-it-forward might be a sustainable model for expanding integrated HIV testing services among MSM in China.Funding: National Institutes of Health, Southern Medical University Dermatology Hospital, Doris Duke Charitable Foundation.

Background: Advances in therapy for hepatitis B virus (HBV) and hepatitis C virus (HCV) have ushered in a new era in chronic hepatitis treatment. To maximise the effectiveness of these medicines, individuals must be engaged and retained in care. We analysed operational interventions to enhance chronic viral hepatitis testing, linkage to care, treatment uptake, adherence, and viral suppression or cure.Methods: We did a systematic review of operational interventions, and did meta-analyses for sufficiently comparable data. We searched PubMed, Embase, WHO library, International Clinical Trials Registry Platform, PsycINFO, and CINAHL for randomised controlled trials and controlled non-randomised studies that examined operational interventions along the chronic viral hepatitis care continuum, published in English up to Dec 31, 2014. We included non-pharmaceutical intervention studies with primary or secondary outcomes of testing, linkage to care, treatment uptake, treatment adherence, treatment completion, treatment outcome, or viral endpoints. We excluded dissertations and studies of children only. Data were extracted by two independent reviewers, with disagreements resolved by a third reviewer. Studies were assessed for bias. Data from similar interventions were pooled and quality of evidence was assessed using GRADE. This study was registered in PROSPERO (42014015094).Findings: We identified 7583 unduplicated studies, and included 56 studies that reported outcomes along the care continuum (41 for HCV and 18 for HBV). All studies except one were from high-income countries. Lay health worker HBV test promotion interventions increased HBV testing rates (relative risk [RR] 2·68, 95% CI 1·82-3·93). Clinician reminders to prompt HCV testing during clinical visits increased HCV testing rates (3·70, 1·81-7·57). Nurse-led educational interventions improved HCV treatment completion (1·14, 1·05-1·23) and cure (odds ratio [OR] 1·93, 95% CI 1·44-2·59). Coordinated mental health, substance misuse, and hepatitis treatment services increased HCV treatment uptake (OR 3·03, 1·24-7·37), adherence (RR 1·22, 1·05-1·41), and cure (RR 1·21, 1·07-1·38) compared with usual care.Interpretation: Several simple, inexpensive operational interventions can substantially improve engagement and retention along the chronic viral hepatitis care continuum. Further operational research to inform scale-up of hepatitis services is needed in low-income and middle-income countries.Funding: World Health Organization and US Fulbright Program.

Background: China has low seasonal influenza vaccination rates among priority populations. In this study, we aimed to evaluate a pay-it-forward strategy to increase influenza vaccine uptake in rural, suburban, and urban settings in China., Methods: We performed a quasi-experimental pragmatic trial to examine the effectiveness of a pay-it-forward intervention (a free influenza vaccine and an opportunity to donate financially to support vaccination of other individuals) to increase influenza vaccine uptake compared with standard-of-care user-paid vaccination among children (aged between 6 months and 8 years) and older people (≥60 years) in China. Recruitment took place in the standard-of-care group until the expected sample size was reached and then in the pay-it-forward group in primary care clinics from a rural site (Yangshan), a suburban site (Zengcheng), and an urban site (Tianhe). Participants were introduced to the influenza vaccine by project staff using a pamphlet about influenza vaccination and were either asked to pay out-of-pocket at the standard market price (US$8·5-23·2; standard-of-care group) or to donate any amount anonymously (pay-it-forward group). Participants had to be eligible to receive an influenza vaccine and to have not received an influenza vaccine in the past year. The primary outcome was vaccine uptake. Secondary outcomes were vaccine confidence and costs (from the health-care provider perspective). Regression methods compared influenza vaccine uptake and vaccine confidence between the two groups. This trial is registered with ChiCTR, ChiCTR2000040048., Findings: From Sept 21, 2020, to March 3, 2021, 300 enrolees were recruited from patients visiting three primary care clinics. 55 (37%) of 150 people in the standard-of-care group (40 [53%] of 75 children and 15 [20%] of 75 older adults) and 111 (74%) of 150 in the pay-it-forward group (66 [88%] of 75 children and 45 [60%] of 75 older adults) received an influenza vaccine. People in the pay-it-forward group were more likely to receive an influenza vaccine compared with those in the standard-of-care group (adjusted odds ratio [aOR] 6·7 [95% CI 2·7-16·6] among children and 5·0 [2·3-10·8] among older adults). People in the pay-it-forward group had greater confidence in vaccine safety (aOR 2·2 [95% CI 1·2-3·9]), importance (3·1 [1·6-5·9]), and effectiveness (3·1 [1·7-5·7]). In the pay-it-forward group, 107 (96%) of 111 participants donated money for subsequent vaccinations. The pay-it-forward group had a lower economic cost (calculated as the cost without subtraction of donations) per person vaccinated (US$45·60) than did the standard-of-care group ($64·67)., Interpretation: The pay-it-forward intervention seemed to be effective in improving influenza vaccine uptake and community engagement.

Background: WHO recommends that men who have sex with men (MSM) receive gonorrhoea and chlamydia testing, but many evidence-based preventive services are unaffordable. The pay-it-forward strategy offers an individual a gift (eg, a test for sexually transmitted diseases) and then asks whether they would like to give a gift (eg, a future test) to another person. This study examined the effectiveness of a pay-it-forward programme to increase gonorrhoea and chlamydia testing among MSM in China., Methods: We did a randomised controlled superiority trial at three HIV testing sites run by MSM community-based organisations in Guangzhou and Beijing, China. We included MSM aged 16 years or older who were seeking HIV testing and met indications for gonorrhoea and chlamydia testing. Restricted randomisation was done using computer-generated permuted blocks. 30 groups were randomised into three arms (1:1:1): a pay-it-forward arm in which men were offered free gonorrhoea and chlamydia testing and then asked whether they would like to donate for testing of prospective participants, a pay-what-you-want arm in which men were offered free testing and given the option to pay any desired amount for the test, and a standard-of-care arm in which testing was offered at ¥150 (US$22). There was no masking to arm assignment. The primary outcome was gonorrhoea and chlamydia test uptake ascertained by administrative records. We used generalised estimating equations to estimate intervention effects with one-sided 95% CIs and a prespecified superiority margin of 20%. The trial is registered with ClinicalTrials.gov, NCT03741725., Findings: Between Dec 8, 2018, and Jan 19, 2019, 301 men were recruited and included in the analysis. 101 were randomly assigned to the pay-it-forward group, 100 to the pay-what-you-want group, and 100 to the standard-of-care group. Test uptake for gonorrhoea and chlamydia was 56% (57 of 101 participants) in the pay-it-forward arm, 46% (46 of 100 participants) in the pay-what-you-want arm, and 18% (18 of 100 participants) in the standard-of-care arm. The estimated difference in test uptake between the pay-it-forward and standard-of-care group was 38·4% (95% CI lower bound 28·4%). Among men in the pay-it-forward arm, 54 of 57 (95%) chose to donate to support testing for others., Interpretation: The pay-it-forward strategy can increase gonorrhoea and chlamydia testing uptake among Chinese MSM and could be a useful tool for scaling up preventive services that carry a mandatory fee., Funding: US National Institute of Health; Special Programme for Research and Training in Tropical Diseases, sponsored by UNICEF, UNDP, World Bank, and WHO; the National Key Research and Development Program of China; Doris Duke Charitable Foundation; and Social Entrepreneurship to Spur Health., (Copyright © 2020 Elsevier Ltd.
