<p><strong>Background: </strong>Young people are at particularly high risk of acquiring sexually transmitted infections (STIs). We conducted a trial to investigate the effect of a community-based intervention that included STI screening among youth on population-level prevalence of STIs in Zimbabwe.</p><p><strong>Methods: </strong>STICH was a parallel-arm, cluster-randomised controlled trial nested within CHIEDZA, a trial of community-based integrated HIV and sexual and reproductive health services for youth in Zimbabwe. STICH was conducted in Harare and Bulawayo provinces with eight clusters in each province, randomised 1:1 to control (existing health services) or to the intervention: community-based screening and treatment for Chlamydia trachomatis and Neisseria gonorrhoeae (males and females) and Trichomonas vaginalis (females only) offered over 12 months to intervention cluster residents aged 16-24 years who were attending CHIEDZA. Outcomes were ascertained through a population-level survey immediately after the intervention period, which included young people aged 18-24 years who lived in randomly selected households in each of the 16 clusters. The primary outcome was population prevalence of any (one or more) of the three STIs; secondary outcomes were prevalence of each of the three STIs. The STICH trial is registered with ISRCTN registry, ISRCTN15013425, and the CHIEDZA trial is registered with ClinicalTrials.gov, NCT03719521.</p><p><strong>Findings: </strong>From Oct 6, 2021, to March 8, 2022, 6361 randomly sampled young people were recruited into the outcome survey (median age 20 years [IQR 19-22], 3500 female and 2101 male, 3066 in intervention clusters and 3295 in control clusters). 5601 participants were included in the primary outcome analysis (2756 in intervention clusters and 2845 in control clusters). In the intervention clusters, 612 (22·2%) of 2756 participants reported that they had attended CHIEDZA and 298 (10·8%) had been tested for C trachomatis and N gonorrhoeae. In the control clusters, 113 (4·0%) of 2845 participants had attended CHIEDZA and 40 (1·4%) had been tested for C trachomatis and N gonorrhoeae. In the outcome survey, the cluster-level geometric mean prevalence of the primary outcome (any of C trachomatis, N gonorrhoeae, and T vaginalis) was 19·07% (geometric standard deviation [GSD] 1·20) in the intervention arm versus 19·95% (GSD 1·10) in the control arm (risk ratio [RR] 0·93 [95% CI 0·78-1·10]; p=0·35). There was no difference between arms in geometric mean prevalence of C trachomatis (12·86% [GSD 1·14] in the intervention arm vs 12·94% [GSD 1·15] in the control arm, RR 0·97 [95% CI 0·84-1·11]; p=0·60) or T vaginalis (7·06% [GSD 1·48] vs 6·20% [1·38], RR 1·09 [95% CI 0·74-1·60]; p=0·66). N gonorrhoeae prevalence was significantly lower in the intervention arm, with a 43% risk reduction (geometric mean 1·65% [GSD 1·77] vs 2·87% [1·43], RR 0·57 [95% CI 0·34-0·96]; p=0·036).</p><p><strong>Interpretation: </strong>

<p><strong>Background: </strong>In all health-care systems, decisions need to be made regarding allocation of available resources.

The scope of the model was health care provided by the public sector in Malawi during 2015-19. Health-care services were delivered during health-care system interaction (HSI) events, which we characterised as occurring at a particular facility level and requiring a particular number of appointments. We developed mechanistic models for the causes of death and disability that were estimated to account for approximately 81% of deaths and approximately 72% of disability-adjusted life-years (DALYs) in Malawi during 2015-19, according to the Global Burden of Disease (GBD) estimates; we computed DALYs incurred in the population as the sum of years of life lost and years lived with disability. The disease models could interact with one another and with the underlying properties of each person. Each person in the Thanzi La Onse model had specific properties (eg, sex, district of residence, wealth percentile, smoking status, and BMI, among others), for which we measured distribution and evolution over time using demographic and health survey data.

DALYs averted were heavily skewed to children aged 0-4 years due to services averting DALYs that would be caused by acute lower respiratory tract infection, HIV or AIDS, malaria, or neonatal disorders.

Background: The REGARD-VAP trial showed that individualised shortened antibiotic therapy was non-inferior to usual care for mortality and pneumonia recurrence in patients with ventilator-associated pneumonia (VAP). We aimed to assess the cost-effectiveness of an individualised shortened antibiotic therapy approach in this planned economic analysis.
Methods: REGARD-VAP was a phase 4, multicentre, open-label, randomised trial to assess a short-course antibiotic treatment strategy for treatment of VAP. In this planned economic analysis, we fitted a decision tree with data from the REGARD-VAP trial to estimate the cost-effectiveness of individualised short-course therapy for VAP, compared to usual care from the health system perspective, in Nepal, Singapore, and Thailand. Incremental cost-effectiveness ratios (ICERs) and incremental net monetary benefits with 95% uncertainty intervals (UIs) were reported against relevant willingness-to-pay thresholds. Parameter uncertainties were evaluated using scenario analyses. A value of information analysis was conducted.
Findings: Adopting individualised short-course therapy was cost-effective for Nepal (ICER=US$1086; percentage cost-effectiveness=50·3%), Singapore (ICER=-$6069; percentage cost-effectiveness=55·2%), and Thailand (ICER=$263; percentage cost-effectiveness=60·5%). The associated incremental net monetary benefits were $41 (95% UI -2308 to 2390) in Nepal, $5156 (-45 805 to 56 117) in Singapore, and $804 (-6245 to 7852) in Thailand. Value of information analysis showed that reducing uncertainties for mortality probabilities, bed-day costs, and variable costs were valuable for decision making.
Interpretation: We found that an individualised short-course antibiotics strategy in patients with VAP is likely to be cost-effective in high-income, middle-income, and low-income settings, although with evident uncertainty. Considered alongside the positive externalities of reduced antimicrobial use, our findings foster confidence in policy makers contemplating adoption of short-course antibiotics.

Background: Surgical-site infection (SSI) is one of the most common health-care-associated infections, substantially contributing to antibiotic use. Targeted antibiotic prophylaxis to prevent SSIs and effective treatment are crucial to controlling antimicrobial resistance (AMR). This study aimed to describe the testing capacity and multidrug resistance (MDR) of SSI microorganisms in low-income and middle-income countries (LMICs).
Methods: This analysis included patients undergoing abdominal surgery in seven LMICs (Benin, Ghana, India, Mexico, Nigeria, Rwanda, and South Africa) as part of the FALCON randomised controlled trial. Wound swabs were collected from patients diagnosed with SSI, as per US Centers for Disease Control and Prevention (CDC) definition. Data on microorganism species and MDR, as per CDC and European Centre for Disease Prevention and Control definitions, were analysed alongside hospital-level data on local microbiological practices. An adjusted analysis was performed to identify perioperative factors associated with MDR. Testing capacity was assessed by the completion of swab testing in positively diagnosed SSIs.
Findings: Between Dec 10, 2018, and Sept 7, 2020, 5788 patients were recruited to the FALCON trial. 1163 patients were diagnosed with an SSI, of whom 905 (77·8%) received prophylactic antibiotics before surgery. In patients with SSIs, 935 of 1163 (80·4%) did not have a wound swab; 195 were from hospitals not performing swabs (15 hospitals) and 740 were from hospitals with capacity but no swab performed (35 hospitals). Of 228 patients swabbed, 200 (88·5%) had microorganisms detected. Escherichia coli (89 of 200, 37·9%) was the most common microorganism and 116 of 200 (58·0%) patients were not covered by the perioperative prophylactic antibiotic. MDR was found in 102 of 147 (69·4%) patients for whom data were available to determine MDR status. Adjusted analysis found that appropriate prophylactic antibiotic coverage (adjusted odds ratio 0·43, 95% CI 0·19-0·96) and regular availability of infection control teams (0·32, 0·11-0·93) were associated with a significant reduction in MDR.
Interpretation: Targeted perioperative antibiotic prophylaxis during contaminated abdominal surgery is insufficient in LMICs, with very few SSI organisms undergoing formal diagnosis. Expansion of testing capacity, development of local guidelines, and implementation of infection control teams could support the prevention of SSI through directed antibiotic prophylaxis, subsequently reducing the burden of MDR.

Testing capacity was assessed by the completion of swab testing in positively diagnosed SSIs.</p><p><strong>Findings: </strong>Between Dec 10, 2018, and Sept 7, 2020, 5788 patients were recruited to the FALCON trial. 1163 patients were diagnosed with an SSI, of whom 905 (77·8%) received prophylactic antibiotics before surgery. In patients with SSIs, 935 of 1163 (80·4%) did not have a wound swab; 195 were from hospitals not performing swabs (15 hospitals) and 740 were from hospitals with capacity but no swab performed (35 hospitals). Of 228 patients swabbed, 200 (88·5%) had microorganisms detected. Escherichia coli (89 of 200, 37·9%) was the most common microorganism and 116 of 200 (58·0%) patients were not covered by the perioperative prophylactic antibiotic. MDR was found in 102 of 147 (69·4%) patients for whom data were available to determine MDR status. Adjusted analysis found that appropriate prophylactic antibiotic coverage (adjusted odds ratio 0·43, 95% CI 0·19-0·96) and regular availability of infection control teams (0·32, 0·11-0·93) were associated with a significant reduction in MDR.</p><p><strong>Interpretation: </strong>Targeted perioperative antibiotic prophylaxis during contaminated abdominal surgery is insufficient in LMICs, with very few SSI organisms undergoing formal diagnosis.

BACKGROUNDThe COVID-19 pandemic has underscored the beneficial impact of vaccines. It also highlighted the need for future investments to expedite an equitable vaccine distribution. The 100 Days Mission aims to develop and make available a new vaccine against a future pathogen with pandemic potential within 100 days of that pathogen threat being recognised. We assessed the value of this mission by estimating the impact that it could have had on the COVID-19 pandemic.METHODSUsing a previously published model of SARS-CoV-2 transmission dynamics fitted to excess mortality during the COVID-19 pandemic, we projected scenarios for three different investment strategies: rapid development and manufacture of a vaccine, increasing manufacturing capacity to eliminate supply constraints, and strengthening health systems to enable faster vaccine roll-outs and global equity. Each scenario was compared against the observed COVID-19 pandemic to estimate the public health and health-economic impacts of each scenario.FINDINGSIf countries implemented non-pharmaceutical interventions (NPIs) as they did historically, the 100 Days Mission could have averted an estimated 8·33 million deaths (95% credible interval [CrI] 7·70-8·68) globally, mostly in lower-middle income countries. This corresponds to a monetary saving of US$14·35 trillion (95% CrI 12·96-17·87) based on the value of statistical life-years saved. Investment in manufacturing and health systems further increases deaths averted to 11·01 million (95% CrI 10·60-11·49). Under an alternative scenario whereby NPIs are lifted earlier on the basis of vaccine coverage, the 100 Days Mission alone could have reduced restrictions by 12 600 days (95% CrI 12 300-13 100) globally while still averting 5·76 million deaths (95% CrI 4·91-6·81).INTERPRETATIONOur findings show the value of the 100 Days Mission and how these can be amplified through improvements in manufacturing and health systems equity. However, these investments must be enhanced by prioritising a more equitable global vaccine distribution.FUNDINGSchmidt Science Fellowship in partnership with the Rhodes Trust, WHO, UK Medical Research Council, Coalition for Epidemic Preparedness Innovations.
