General overview • Web-based application used to collect cancer data securely over the public Internet • Ideal for use by central registries for reporting from physicians’ offices, low volume facilities, nonhospital reporting sources, and for followback efforts • Allows data sets and edit sets to be customized by central registry
General overview • Data entered are validated by the CDC EDITS Engine running on a web server • Records are saved in a database at the hosting central registry and cases entered by one facility or office are not visible to other facilities • Hosted on a secure web server that has a digital certificate installed – communication between client and server is encrypted with Secure Socket Layer (SSL) technology
Features • Eliminates need to distribute and maintain software at these facilities • Supports all data items in national standard data sets, including text • User display types and edit configurations are managed at the hosting central registry • Provides on-demand reports to users • Supports file upload of abstracts • Includes most functionality of Abstract Plus
Web Plus System Architecture Web Plus User Demilitarized zone Web Plus Database External Firewall Internet Information Services Hosting Web Plus Internal Firewall SQL Server
Web Plus Security • • • Form-based authentication (User. ID, password) Role-based access to functions User actions are logged and are available for audit Facilities can only view their own abstracts System security is the responsibility of the central registry: – securing network infrastructure – configuring web server for security – installing digital certificates on web server and optionally on client’s for SSL encryption/server validation – fault tolerance, backup plans, etc.
Capabilities - Abstraction • Lookup assisted data entry with advanced search feature • Link for each data item to the NAACCR Standards for Cancer Registries Volume II: Data Standards and Data Dictionary for information about the data item • Code selection from drop-down lists • Calculation of Age at Diagnosis • Supports Collaborative Staging calculation
Capabilities – Data Editing • Display types are configured by central registry – Ordered subsets of standard NAACCR and local data items collected by the central registry – Critical fields • Allows assignment of different display types and edits for different facilities and types of cancer reporters • Abstracts are entered and edited using the display type and edit set assigned to the facility • Edits are re-run each time an abstract is saved, and remaining errors displayed for correction
Display Type Section Headers Critical Field Link to NAACCR Standards Data Item Labels Drop Down List Special Lookup
Web Plus Roles • Role-based access to functions – File Uploader – Central Registry Administrator – Local Administrator – Facility Abstractor – Central Registry Abstractor
File Uploader – Facilities can submit bundles of abstracts in the NAACCR format – Files run through Edits validation upon submission – Error report available after upload
File Uploader • Supports automated rule for file acceptance – Accept if less than n% of records have errors • Administrator can override automated rules – Accept or Reject • Option for offline, batch running of edits on large files and under heavy load conditions available
Central Registry Administrator • Manages facilities and users at both central registry and facilities • Configures display types, edit sets and system preferences • Manages assignment of abstracts to central registry staff • Exports data and views reports
Central Registry Administrator Generating Display Types
Local Administrator • Manages local users of a facility • Views reports
Facility Abstractor • Enters abstracts and corrects errors until abstract is complete (no errors remain) • Releases abstracts to central registry • Views reports
Central Registry Abstractor • Reviews abstracts released to the central registry, verifying submitted codes with submitted text • Enters new abstracts • Releases abstracts for export into the central registry
Reports Central Registry Reports • System Log-ins • Abstract Updates • Abstract Searches • Abstract Deletions • Abstract Exports • Abstract Releases
Reports Facility Reports • Abstracts Submitted Sorted by Abstractor • Abstracts Accessed Sorted by Patient Name • Descriptive Statistics on Released Abstracts • Activity Report • HIPAA Accounting of Disclosure Report
Web Plus Next Steps • Add follow back procedures – Physician Death Certificate Follow-back – Physician Path Lab Follow-back • Add Pathology Lab HL 7 parser • Usability Studies • Expand use of Web Plus
