Introduction The World Health Assembly approved resolution WHA60.29 on Health Technologies in May 2007. This resolution requested the WHO Director-General:
a needs-finding tool
Needs-finding Determining how to equip a healthcare facility with medical devices is a complex task. It involves a consideration of service delivered, infrastructure availability and setting [2].
As a result, a medical devices database can provide a valuable tool for:
• Member States in healthcare facility planning
• Funding agencies
• Industry - respond to global health concerns [3]
References [1] – WHA60.29 Health Technologies, Resolution from the 60th World Health Assembly (May 2007) [2]– WHO, Regional Office for the Western Pacific, District Health Facilities – Guidelines for Development & Operations, Manila, Philippines (1998) [3] – WHO, Department of Essential Health Technologies, Landscape Analysis – Global Initiative on Health Technologies, Geneva, Switzerland (July 2009)
Existing research WHO WHO has already undertaken a large part of the research into medical device distribution. Two sets of medical device lists have been developed by WHO:
• Medical Devices per Facility – for Health Post, Health Centre, District Hospital, Provincial Hospital and Specialized (Teaching) Hospital
• Medical Devices per Disease – relating to device to each step/procedure in a clinical care guideline at various levels
Both lists contain information from ICD as well as from both Medical Device Nomenclature systems (GMDN & UMDNS). Others Other centres have also published data on device priority, technical specifications (i.e. CENETEC – Mexico and Directorate of Biomedical Engineering – Jordan) and Health Technology Assessment.
Aims & Objectives Our database aims to consolidate existing research (see right) to:
•Store information about the use of medical devices in different healthcare facility and settings
•Store information about the use of medical devices in different clinical practice guidelines
•Query above information according to a wide range of criteria
•Be web-based and publically available whilst being selectively updated by an expert group
This poster highlights the department's efforts at constructing this database and arose out of a number of summer interns' work in 2010. It involves integrating a wide range of existing research into one database.
"to establish and update regularly an evidence and web-based
health technologies database to serve as a clearing house which
will provide guidance on appropriate medical devices according to
levels of care, setting, environment and intended health
intervention, tailored to the specific needs of country or region;" [1]
Figure 1 – Poor needs assessment leads to lack of useful equipment
Use scenarios Input Data will be inserted by certified users from WHO using input forms or directly through table importing. This happens at the different levels of the database.
Search Users can search through a combination of data parameters using queries. Here are some sample searches:
Devices used in Paediatric Pathways that can be used at health centre level
Clinical Pathways/diseases fully treatable in a district hospital
10 most crucial devices at health post level
Output Data from above searches can be extracted in a variety of formats, including PDF table reports, Dynamic forms, Spreadsheet table, Table on Screen
Future Work This database is expandable with a variety of new data sources from different member states and organizations, including:
Information from the WHO EHT Baseline Country Survey on Medical Devices
Integration with existing medical device nomenclature systems
Lastly, all information should undergo a thorough expert and evidence-based medicine review.
In order to make it fully-accessible, this database should be adapted to a web-based platform (SQL or myPHP) and be hosted by WHO.
Ultimately this database will provide a valuable needs-finding tool for member states. This will allow for the right equipment in the right place to treat the right condition.
Database Structure In order to integrate all the existing data into one searchable database we have linked everything to the medical device. Figure 2 below shows the data structure and figure 3 relates this to input forms (on Microsoft Access).
