Background Globally, critical illness results in millions of deaths every year. Although many these are potentially preventable, the basic, life-saving care critically ill patients often overlooked health systems. Essential Emergency and Critical Care (EECC) has been devised as that should be provided to all hospitals world. EECC includes effective low cost complexity for identification treatment across medical specialties. This study aimed specify content additionally, given surge ongoing...
Despite known gender-specific differences in terms of prevalence, transmission and exposure to neglected tropical diseases (NTDs), there is limited discussion the influence gender NTD programmes interventions. There a paucity research on how interacts with service provision uptake. This study, part broader implementation Ethiopia, applied lens health seeking for five NTDs: lymphatic filariasis, podoconiosis, schistosomiasis, soil-transmitted helminth infection trachoma.The study was...
Aim To explore healthcare providers’ perceptions and experiences of the implications a patient data-sharing agreement between National Health Service (NHS) Digital Home Office on access to NHS services quality care received by migrant patients in England. Design A qualitative study using semi-structured interviews, thematic analysis constant-comparison approach. Participants Eleven providers one non-clinical volunteer working community or hospital-based settings who had experience migrants...
Numerous studies highlight the effectiveness of an integrated approach for management malaria, pneumonia and diarrhoea at community level. There has however been little study on lessons learnt from implementation in practice stakeholder experiences which could inform future programmatic planning evaluation frameworks. A participatory, qualitative was conducted three varied settings South Sudan, Uganda Zambia, have seen scale up case (iCCM) over last five years. All key in-country...
Background: Pneumonia heavily contributes to global under-five mortality. Many countries use community case management detect and treat childhood pneumonia. Community health workers (CHWs) have limited tools help them assess signs of New respiratory rate (RR) counting devices pulse oximeters are being considered for this purpose.Objective: To explore perspectives CHWs national stakeholders regarding the potential usability scalability seven aid assessment pneumonia signs.Design: Pile sorting...
Introduction Genomic data constitute a valuable adjunct to routine surveillance that can guide programmatic decisions reduce the burden of infectious diseases. However, genomic capacities remain low in Africa. This study aims operationalise functional malaria molecular system Mozambique for guiding control and elimination. Methods analyses prospective seeks generate Plasmodium falciparum genetic (1) monitor markers drug resistance deletions rapid diagnostic test targets; (2) characterise...
Low blood oxygen saturation (SpO2), or hypoxaemia, is an indicator of severe illness in children. Pulse oximetry a globally accepted, non-invasive method to identify but rarely available outside higher-level facilities resource-constrained countries. This study aims evaluate the performance different types pulse oximeters amongst frontline health workers Cambodia, Ethiopia, South Sudan, and Uganda.Five (POx) which passed laboratory testing, out initial 32 potential oximeters, were evaluated...
Once a mainstay of malaria elimination operations, larval source management (LSM)-namely, the treatment mosquito breeding habitats-has been marginalized in Africa favour long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS). However, development new technologies, mosquitoes' growing resistance to insecticides used LLINs IRS raise renewed interest LSM.A digitally managed larviciding (DML) operation three seven districts São Tomé Príncipe (STP) was launched by Ministry...
Malaysia has rising dengue incidence. World Health Organization clinical practice guidelines for managing have been adapted by the Ministry of in Malaysia, with evidence good awareness clinicians. However, mortality not reduced. This study aimed to explore challenges management Medical Officers, a particular focus on use guidelines.Qualitative using six groups and 14 semi-structured interviews doctors responsible at large tertiary hospital Malaysia.Dengue was recognised as difficult diagnose...
Background Malaria is a significant cause of morbidity and mortality in children aged under 5 years Mozambique. The World Health Organization recommends seasonal malaria chemoprevention (SMC), the administration four monthly courses sulfadoxine-pyrimethamine (SP) amodiaquine (AQ), to 3-59 months during rainy season. However, as resistance SP widespread East Southern Africa, SMC has so far only been implemented across Sahel West Africa. Objective This protocol describes first phase pilot...
Cambodia has one of the highest dengue infection rates in Southeast Asia. Here we report quantitative entomological results a large-scale cluster-randomised trial assessing impact on vector populations package control interventions including larvivorous guppy fish household water containers, mosquito trapping with gravid-ovitraps, solid waste management, breeding-container coverage through community education and engagement for behavioural change, particularly participation school children....
Pneumonia is one of the leading causes death in children aged under 5 years both sub-Saharan Africa and Southeast Asia. The current diagnostic criterion for pneumonia based on increased respiratory rate (RR) with cough or difficulty breathing. Low oxygen saturation, measured using pulse oximeters, indicative severe pneumonia. Health workers often find it difficult to accurately count number breaths, RR counting devices are use unavailable. Nonetheless, improved low-cost oximeters now...

During the early stages of COVID-19 pandemic, concerns were raised about reduced attendance at hospitals, particularly in paediatric emergency departments, which could result preventable poorer outcomes and late presentations among children requiring care. We aimed to investigate impact on health-seeking behaviour decision-making processes caregivers presenting services a National Health Service (NHS) Trust London.We conducted mixed-methods study (survey semi-structured interviews) across...
