There are about 131 clinical studies being (or have been) conducted in Cambodia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Seek the simple tool as questionnaire for screening hearing loss. The FMHT was developed by American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS). It is a standard hearing questionnaire. So, we plan to translate the FMHT into Cambodian language and validate by comparing its result with those of audiometry.
A Friendship Group (FG's) (n= 4) will be delivered over an 8-week period (December 2021 - January 2022) to individuals who met the clinical distress threshold as per Kessler-10 score. FG's were offered face-to-face in Phnom Penh (n= 2) and online via Zoom (n= 2). Trained, community support workers and Prosthetists' from the Cambodian School of Prosthetics and Orthotics delivered FG's each week.
A rabies virus neutralizing antibody (RVNA) concentration ≥ 0.5 IU/ml at 14 days after immunization is considered a proxy for protection in vaccine efficacy studies. Abridged and dose-sparing vaccination regimens increase accessibility and reduce both direct and indirect costs, especially in resource-constrained countries where RABV prevalence is highest. Several efficacy studies evaluated safety and immunogenicity of abridged regimens in healthy adult volunteers using either four-site intradermal (ID) or intramuscular (IM) regimens, showing them to be safe and immunogenic. Researchers at the Institut Pasteur du Cambodge (IPC) have previously conducted a retrospective study on clinical outcome at ≥6 months in 3318 Cambodians who received intradermal Vero cell vaccine post-exposure prophylaxis after a bite by a rabid or sick-looking but untested dog in 2003-2014. Here, the investigators could show that there was no significant difference in survival among patients who received 3 versus 4 sessions of the Thai Red Cross (TRC) ID regimen. In a separate study, investigators measured antibody responses in order to evaluate the immunogenicity of the TRC regiment after 3 sessions versus 4 sessions. The investigators did not observe an increase in rabies virus seroneutralization titers 14 days after the fourth immunization compared to 14 days after the third immunization. These results contributed to changes endorsed by the WHO in its April 2018 guidelines. The "Institut Pasteur du Cambodge (IPC) regimen" of three PEP sessions of two-site ID 0.1 mL vaccine doses each at days 0, 3 and 7 is the first one-week PEP regimen to be recommended. In the current research project, the aim is to compare further different PEP vaccination strategies in a real life setting of individuals attending the rabies vaccination center at Institut Pasteur du Cambodge (IPC) in Phom Penh, Cambodia. The antibody kinetics and cellular immune responses in patients following either the one-week, 2-site ID regimen (IPC regimen) or the two-week IM regimen (4-dose regimen) as well as the participants' survival for both protocols after 6 months are evaluated.
The Innovative Mobile Technology for Maternal and Child Health Care (i-MoMCARE) project is a digital health intervention aiming to increase the coverage of and access to maternal and child health (MCH) services for pregnant women and their babies in rural communities in Cambodia. We will fully adopt an innovative model (ImTeCHO) developed, successfully implemented, and evaluated by Society for Education, Welfare and Action-Rural (SEWA Rural) in Gujarat, India. This study will take advantage of Cambodia's well-structured healthcare system, increased internet coverage, and the sharp rise in smartphone adoption to implement innovative mobile technology intervention. i-MoMCARE will provide village health support groups (VHSGs) access and training in mobile-based job aid (mobile apps) to facilitate their work with pregnant women and mothers in the villages. Using mobile apps, VHSGs can register pregnant women and mothers, (re)schedule health care appointments, develop a digital record of the medical history of pregnant women and mothers, show educational videos to pregnant women and mothers, and alert health center staff on high-risk cases. i-MoMCARE will also offer health center staff access to the web interface where they can do longitudinal tracking of VHSGs' log-in rate, track the medical history of patients, and screen for complications and referrals. In Cambodia, long distances to health facilities and inadequate education for women of reproductive age are among the determinants of poor health outcomes, predominantly in rural communities, where the demand for MCH services is high. VHSGs could help overcome the long distance to health facilities with mobile technology. i-MoMCARE could also improve women's understanding of the importance of regular antenatal and postnatal utilization and vaccination and, by extension, reduce high-risk cases and maternal and child deaths. This study is the first to be implemented in Cambodia, contributing to the use of digital health in MCH interventions, which remain in their infancy.
Hospital-acquired infections (HAIs) are significant public health issues, especially in low- and middle-income countries (LMICs). Hand hygiene and low-level disinfection of equipment (LLDE) practices among healthcare workers (HCWs) are essential to reduce HAIs. Various effective infection prevention and control (IPC) interventions to reduce HAI incidence have been developed. However, which interventions work effectively in LMICs has not been identified. The investigators aim to develop, pilot, and assess the feasibility and acceptability of an IPC intervention in Cambodia and the Lao People's Democratic Republic (PDR).
Environmental hygiene is a key component of infection prevention in healthcare, and a driver of healthcare associated infections. Staff who clean in many low resource countries receive no formal training on cleaning, waste disposal and linen handling. This issue has been execrated by the COVID-19 pandemic. The only recommended training on environmental hygiene for low resourced facilities, TEACH CLEAN, uses a training of trainers model. A selected cadre "champions" which in turn train their peers with responsibilities on environmental hygiene at the facility level. Early pilot data to test its effectiveness of this training package are very promising. The main objective is to evaluate the effectiveness of an environmental cleaning bundle to improve microbiological cleanliness in Cambodian hospitals. The latest TEACH CLEAN will be implemented across all hospitals (13) of three provinces in Cambodia. A stepped wedge randomised trial will be used to evaluate the effectiveness of TEACH CLEAN to improve microbiological cleanliness in Cambodian hospitals. All facilities will receive the intervention. Hospitals are arranged in groups of three or four based on the randomisation with staggered commencement dates of the intervention at four distinct time points. The design will include ten months of data collection. We expect one month gap between the training of champions and the training of staff at the facility level. The main outcome is microbiological cleanliness (<2.5 cfu/cm2 = clean ; ≥2.5 cfu/cm2 = not clean) measured using a non-specific agar on one side for measuring total Aerobic Colony Counts (ACC/cm2). With 30 sampling sites in each hospital and with a pre-training cleanliness proportion ranging from 30% to 50% will give us over 85% power to detect a 10% absolute post-intervention increase in cleanliness. Evidence from this trial will contribute to future policy and practice guidelines about hospital environmental hygiene and ultimately reduce healthcare associated infections. This would be the first randomised trial on environmental hygiene in low resource settings.

This cross-sectional household survey design to recruit a random sample of households that is representative for each of the study sites. From the selected households, all consenting, household members will be included in the study. This study is funded by the UK Wellcome Trust. The grant reference number is 215604/Z/19/Z
Hypothesis: - Hypothesis 1 : Regarding the recentness of preexposure prophylaxis (PrEP) implementation with an uptake of 20% and according to the first consultative meeting, awareness and acceptability of PrEP seems to be low in key-populations of Cambodia - Hypothesis 2 : Individual, social and structural barriers and facilitating factors of PrEP implementation as perceived by health workers and community-based organizations would be similar to what was observed worldwide 4,8. - Hypothesis 3: Some subgroups of key-populations are difficult to reach in health facilities. Community organizations can play a critical role to provide PrEP information, initiation and counselling with the support of new technologies. - Hypothesis 4: Community organizations might lack financial, logistical and skill capacities to deliver PrEP in good conditions Main objective: • To qualitatively evaluate the knowledge, awareness, perception, experience and acceptability of PrEP among key populations (entertainment workers (EW), men who have sex with men (MSM), transgender women (TW)), and among healthcare and community workers in charge of key populations Secondary objectives: - To better understand the characteristics, needs and expectations of community-based organizations (CBOs), in order to define the optimal conditions for community-based PrEP implementation - To identify tools that could be useful to increase PrEP awareness and acceptability, especially new technologies (apps, websites) Methodology: Qualitative study Focus groups with key-populations, healthcare and community workers Semi-directive interviews with decision makers and policy makers Estimated enrolment: 10 participants per focus group, 8 focus groups, 80 participants in focus groups, 6 interviewed persons, 86 participants in total Study population: Men who have sex with men (MSM), entertainment workers (EW), transgender women (TGW), healthcare workers, community workers, decision and policy makers
