Objectives of this lecture
Provide an overview of information system types and potential uses
Increase awareness on need to balance amount of data with cost and confidentiality concerns
Present case scenarios to set up and enhance information systems
Characteristics of Good Health Surveillance Systems
Clear objectives • administration
• routine documentation
• monitoring
• research/evaluation
Simple (MDS)Standard item formatJustification and validation of items
Characteristics of Good Health Surveillance Systems (cont)
•Relevant to users•Minimum burden to providers•Amenable to modification•Provision for security/confidentiality•Associated reporting system •Feedback to collectors•Linked to action
Options
•Paper-based centralised
•Sentinel/selected surveillance
•Computerised stand alone
•Single site
•Multicentre
Options
•Computerised networked
•Encrypted data transfer
•Combination
•Paper-based notifications
•electronic entry at central location
Setting up a Health Information
System
Which option is best?
SCENARIO: Cholera epidemic in Africa
No routine surveillancePoorly kept clinical recordsUnderstaffed facilitiesUnreliable communicationsNo ongoing fundingNo computers
Cholera epidemic in Africa
Example of a paper-based system that worked in an endemic area for at least 2 years
Occupational exposure to bloodborne illnesses among health staff
Hundreds of health facilitiesInfrequent incidentsNon-compulsory recordingNo ongoing fundingConfidentiality issuesCompensation issues
Nutritional Status Monitoring in a remote indigenous community
Routine surveillance of some conditionsSomehow comprehensive clinical recordsServices staffed by communityUnreliable communicationsSome funding availableSome computers usable
•How the data will be collected•How the data will be used•Who will have access to the data•Confidentiality issues•Perceived discrimination•Financial implications
Major stakeholder’s concerns
Indigenous Community Health
Computerised systemEasy front-endComplete patient information (alias/residence)Promotes opportunistic P.H. actionCapability for health worker plans Population based reporting systemGenerates customised prevalence/incidence
Burden of depression at Medical Practitioners rooms
Non-standard recording practices ? Availability of clinical recordsBusy medical practicesVariable communication systemsLow computer coverageEthical issuesIncentives required for doctors
Doctors-based Sentinel Surveillance
•Enables documentation of non-hospital data•Burden of disease measurement•Paper-based with weekly notifications•Limited patient information & # conditions•Selected Locations (self-selected doctors)•Inability to calculate prevalence/incidence
