Data Collection
- What are the human resource requirements for data collection/entry?
- What are the on-going, non salary costs associated with data collection and entry requirements?
Data Maintenance
- What are human resource requirements for maintenance of the system?
- What are the on-going non salary costs associated with maintaining the system?
Data Establishment
-
li>What were the human resource requirements for establishment?
- What were the non salary expenditure costs?
Data Storage
- What data storage system is used – off-the-shelf or purpose-designed?
Data Collection
Sources
- Is data collection passive or active i.e. is data actively sought or passively received?
- Providers – what are the sources of the data?
- How is the source target population defined, i.e., occupation, industry, geographic area or other?
Medium
- In what format is the data collected, e.g., hard copy, electronic?
Ethical/privacy requirements
- What ethics/privacy issues had to be dealt with to meet privacy requirements in its local jurisdiction?
Multiple exposures
- Does the surveillance system capture data on simultaneous or multiple exposures?
Frequency
- What is the frequency or periodicity, i.e., is the data collection continuous, or periodic? If periodic, what are the time intervals?
Inclusions/exclusions
- What data is included and excluded in the collection process?
- Type of data, e.g., qualitative, quantitative, semi quantitative?
Coding
- How is the data coded, e.g., for retrieval?
Reliability
- Is the reliability of data assessed, e.g., reliability/reproducibility of exposure measures, are data sources assessed or verified, are confidence levels determined?
- Variability – does the data collection method account for irregular exposure patterns, e.g., itinerate or seasonal workers?
Exhaustiveness
- Is there any sense of the degree to which data pertaining to the target population is captured?
Geographical range
- Does the data collection tool cross geographical boundaries?
Data Uses
Users
- Who is the data aimed at, i.e., who are the intended prime users of information collected, e.g., host organisation, government agencies?
- Who or what are the main users of the information?
Links/interrelated
- Is the data linked to other databases?
Presentation
- How is the data presented, e.g., raw data in database form, via reports/hard copy, electronic?
- If reports are generated, what is the frequency, e.g., weekly, monthly, annually?
Transferability
- Is it intended that the data might be available for transfer to other databases?
