components of hiv surveillance: case reporting process
TRANSCRIPT
Review of Sessions To DateOverall:
Overview of Case and Second Generation Surveillance
Minimum needs and activities required
Country-Specific: Definition of what you want to know about HIV Identification of existing data sources Rapid situational assessment of data, systems,
environment
Session Overview We will discuss:
A. Moving prioritized data from collection point to central point
B. Using existing data flow systems and structures, or building new ones
C. Data management of case dataD. Data quality assurance and improvementE. Staffing roles and responsibilities
Moving Data Case Surveillance can only occur if data are
transferred from the point of patient interaction to a central point for data management
Three criteria should be considered: Format(s) of the data Method(s) of data transfer Pathway(s) of data transfer
Moving Data – Format
Data Format

Points to Consider:•Existing Systems•Existing Relationships•Staffing Resources•Capacity of Levels
Using Existing Systems Existing Systems Could Include:
EMRs Has data and existing reporting pathways
Other Disease Reporting Systems Has existing reporting pathways and staff roles and
responsibilities
M&E Systems Has existing reporting pathways and staff roles and
responsibilities Could be via a regional government office and/or umbrella
organization
Other Reporting/Supply Chain Systems Has existing pathways and staff roles and responsibilities
Could be via a regional government office and/or umbrella organization
Using Existing Systems Steps Needed:
1. Definition of output Case surveillance data, format, and frequency of transfer
2. Mandate, and strong partnership Support of government, funder, implementer, and programs Policy and procedures put in place (confidentiality, data
sharing)
3. Understanding of Systems’ inputs Where do data come from? In what format? With what
frequency?
4. Understanding of Systems’ structure What is the ‘platform’? Is the platform expandable?
Using Existing Systems Steps Needed (cont.):
5. Draft model of data transfer and/or extraction Programming of data fields and/or extraction process Collaboration with identified staff positions
6. Create master database to receive inputs Simple system to allow for real-time data management
7. Pilot and testing of the new model and system Practice data entry, data extraction, and/or data
transfer process Ensure viability of data received
8. Refine systems and processes Troubleshoot before implementation!
Using Existing Systems Steps Needed (cont.):
9. Create Standard Operation Procedures and Manuals Define and document all the steps and the requirements
10. Create training materials for those involved Cover all points that will ensure buy-in and success
11. Prepare for system roll-out Train involved staff Sign data sharing and confidentiality agreements with all
required
12. Launch system Support, monitor, support, monitor, refine, support,
monitor, refine
Expanding Systems Expanded Systems Could Include:
Paper-based system
Electronic systemServer-based or Web-based
Dual paper/electronic system
National systemAll possible inputs
Representative systemAll ART sites; all government sites; etc.
Expanding Systems Steps Needed:
1. Definition of output2. Mandate, and strong partnership3. Definition of System’s inputs4. Definition of System’s structure5. Draft model of data collection and transfer6. Create master database to receive inputs7. Pilot and testing of the new model and system8. Refine systems and processes9. Create Standard Operation Procedures and Manuals10. Create training materials for those involved11. Prepare for system roll-out12. Launch system
Value of Web-based Systems Accessible any time of day Statistics are instant and data downloads are
always the most current versions Program updates do not need to be distributed
to users since the program “lives” on the server
The only program users need is a web browser User interfaces utilizes standard website
controls that people are accustomed to Multiple users can access the system at the
same time from different locations System can be accessed from anywhere in the
world with internet access
Managing Data Data Management includes such
questions: Are the correct data collected Are the correct data entered Are the correct data in the system Are the correct data cleaned Are the correct data usable Are the correct data available for use
Data Management must happen at every level: Site level Regional level National level
Data Management must include Feedback loops

Region
Central
Managing Data – Site Level At the site level, attention should be paid to:
Clear definitions and support Are there clear policies and procedures? Do staff know what they are supposed to do?
May include data collection, data entry, data validation, data transmission, etc.
System function Are data being collected and inputted into the system? Are staff doing their work? Are staff supported to do their work?
Data use Can sites access their data? Do sites get feedback on their data? Do sites use their data?
Managing Data – Regional Level At the regional level, attention should be paid to:
Clear definitions and support Are there clear policies and procedures? Do staff know what they are supposed to do?
May include data collection, data entry, data validation, data cleaning, data deduplication, data transmission, etc.
System function Are staff doing their work? Are staff supporting the sites? Are staff supported to do their work?
Data use Can regions access their data? Do regions get feedback on their data? Do regions use their data?
Managing Data – National Level At the national level, attention should be paid to:
Clear definitions and support Are there clear policies and procedures? Do staff know what they are supposed to do?
May include data collection, data entry, data validation, data cleaning, data deduplication, data transmission, etc.
System function Are staff doing their work? Are staff supporting the sites? The regions? Are staff supported to do their work?
Data use Is there a clean national data set? Do regions and sites get feedback on their data? Are national data being used?
Managing Data – Special Considerations 1. Patient Identification
What it is A unique way to identify each case (person)
Why it is important Patient identification is important if we want to have a
unique count of persons infected with HIV Patient identification allows patient tracking over time Each event is entered into the system to determine if it is a
unique (new) record. Some will be new cases; some will be an update to an existing patient in the system. Updates include: Transition from HIV to AIDS A pregnancy A visit to a different clinic system A death
Managing Data – Special Considerations 2. Data Deduplication
What it is An evaluation and assessment of each case entered
into the system to determine if it is a unique (new) case, or if it is an update on an existing patient in the system
Why it is important Deduplication is important if we want to have a unique
count of persons infected with HIV Deduplication, and matching records to the source file,
allows patient tracking over time
Managing Data – Special Considerations
2. Data Deduplication How it can be done
Manually or automatically
Cases are matched by certain selected criteria: Unique ID Code - Each record needs one for each patient
Ideally, people have national identifiers (and they are used!) before a record is entered
More often a unique identifier must be established from some combination of common demographic information
The more unique, the more certainty that records are for the same person
Combination of other variables that are somewhat unique: Name Parents Names Date of Birth Location of Birth Location of Residence
Records that match are appended to each other to track over time
Managing Data – Special Considerations
Step Records must match on exactly on
1First name, Last name, Year of birth, Month of birth, Sex, Patient code
2 same as (1) without Patient code3 same as (1) with just with first four letters of Frist name
4First name, Last name, Year of HIV diagnosis, Institution, Data source, Patient code
5 same as (4) without Patient code
6First name, Last name, Year of HIV diagnosis, Town of birth, Patient code
7 same as (6) with Mother’s name
We try to do it automatically first:
If records do not meet the criteria, they are subset and reviewed by qualified personnel. We refer to this as manual review.
The manual process is manageable if done in a timely manner. Otherwise, a backlog could develop.
Data Deduplication Example: Haiti System
Managing Data – Special Considerations 3. Data Validation
What it is A review of data to see that what is submitted is accurate Examples:
Are the report dates more recent than the last data transfer? Does everyone have a birthdate? How many fields are completely empty?
Why it is important Speaks to the quality of the data People make mistakes. The wrong file can be uploaded,
data can be deleted, or records can be shifted. How it can be done
Chart review (sub-set) vs. submitted data Record review (sub-set) vs. submitted data
Quality Assurance and Improvement Quality Assurance (QA) allows one to assess
the quality of the system and the data to: Implement improvement activities Speak to the strength of the resulting data
Quality Improvement (QI) occurs from the QA process, and allows one to refine and improve the system and data Quality Improvement should be an ongoing
activity: “continuous quality improvement” (CQI)
Quality Assurance and Improvement QA and QI can be self-defined, per the system
and environment, but should consider: Data Quality
Do the data in the master system match those from the sites?
Data Completeness Are all variables expected received?
Timeliness of Data Are data received in a timely manner (one week vs. one
month) System Representativeness
Do data in the system represent the country, or a sub-set?

What are the Personnel Needs? System Management and Oversight
Site/Clinic-level surveillance lead District or provincial surveillance lead National surveillance lead
Data Management Data entry clerks at appropriate level (depending on
where data are entered) National-level data manager
Define Roles and Responsibilities: Data quality Cleaning and merging data Data reports IT support
Roles and Responsibilities: Site Level Needs:
Complete forms for newly diagnosed cases Complete forms for changes in clinical status Complete forms at death of HIV-infected persons Submit forms to the next level per the reporting
chain, maintaining confidentiality Record each instance of case reporting on a
patient’s clinical record to the surveillance programme
Who will do this? Dedicated staff or additional role/task shifting?
Roles and Responsibilities: Regional Level Needs:
Receive, review, manage HIV case reports in a timely manner
Ensure that case reports are filled out completely, accurately and clearly; provide training and TA as needed
Follow-up on cases of epidemiologic importance Implement quality improvement initiatives
Are case reports complete, with quality data? Are all cases reported?
Compile and clean data Disseminate data
Who will do this? Dedicated staff or additional role/task shifting?
Roles and Responsibilities: National Level Needs:
Develop and operationalize guidelines on HIV case reporting Train and assist sub-national surveillance programs,
including facility-level personnel Maintain a complete and accurate HIV case database that is
secure, with access limited to authorized personnel Analyse, interpret and disseminate HIV case reporting data Assess the performance of the surveillance programs by
monitoring surveillance activity Provide overall guidance and training for sub-national
programs
