简要总结
The project rolls out combined innovative low-tech thermotherapy with heat packs and WHO recommended wound management in a Buruli ulcer (BU)-endemic district of West Africa. It addresses three key areas of considerable clinical and public health importance in the region:
- to better help people managing the disabling disease BU that primarily affects children in West Africa
- to implement WHO recommended general wound management for all types of wounds with tools available at the peripheral level of the health care system
- to prevent systemic life threatening sequelae (e.g. sepsis and rheumatic fever) and permanent local damage (e.g. motor and sensory disability) by early recognition and treatment of wounds at the community level. The project translates available research findings already validated on the secondary health care level into clinical practice at the periphery (primary health care level). The string of the investigator's previous work from the development of the BU thermotherapy-wound management-package to the proof of its efficacy provides all necessary skills, tools and documents to immediately proceed into practical community application.
Operational endpoints are
- coverage and quality of WHO recommended wound management training of health care personnel at the primary health care level (health posts);
- coverage, success rate and quality of care for patients with BU and other wounds; denominator controlled at health post level and high-quality Health and Demographic Surveillance Systems (HDSS) data.
The project is embedded into a stable multidisciplinary working environment at Côte d'Ivoire, including an HDSS with a longstanding record of partnership and successful community-based operational research.
The project builds on the principles laid out by the Sustainable Development Goals (SDGs) and Universal Health Coverage (UHC) and
- targets all patients with a broken down skin barrier independent of the cause (patient centred health care)
- brings diagnosis and treatment close to the community
- educates and trains both community members and health care workers
- measures the health intervention outcome The project is fully in line with the new integrated strategy for the skin NTDs of WHO's Department of Control of NTDs (WHO/NTD).
详细描述
Overall goal of the study To contribute to a better understanding of the clinical epidemiology of wounds and wound healing and to improve wound management in settings with limited resources at the community level, the primary and secondary level of the health care services.
Study objectives Main study
-
To measure the proportion of wounds healed (defined as wound closed) at each cycle of clinical diagnosis and the corresponding presumptive treatment
-
To describe the clinical epidemiology of wounds presented (presumptive clinical and confirmed diagnoses)
-
Coverage and quality of wound management training of health care personnel at the peripheral health care level (health posts); Substudy 1
-
To measure the effectiveness and acceptability of thermotherapy of patients with early BU (< 2cm) treated at health post level with the following outcomes:
-
Primary endpoints absence of clinically BU specific features' according to WHO guidelines or 'wound closure' within 6 months after completion of heat treatment ("primary cure") and 'absence of BU recurrence for 12 months after completion of heat treatment' ("definite cure").
-
Secondary outcomes rates of withdrawal for low compliance consent withdrawal rating of thermotherapy by health staff Substudy 2
-
To measure the frequency and the severity of skin lesions (broken skin barrier) in the community and the health services
-
To investigate the determining factors of community and health services-based wound management
-
To measure the impact of the wound management intervention (main study and substudy 1) on the frequency, spectrum and severity of wounds including systemic complications in the community and at the 7 health posts / district hospital (HDSS-based) compared to the baseline study before the intervention and over time after the implementation of the intervention.
Target Population The target population are approximately 43,000 people of the Taabo HDSS which is surveyed longitudinally for key demographic, health and socioeconomic indicators since 2008. This provides ideal conditions to implement the intervention and assess the impact through operational endpoints. The health centres and the district hospital involved are part of the public health system. There is one district hospital and the seven health posts within the Taabo DHSS.
