1 Using subset for pathology data retrieval Mr Barry Fong, Mr Kent Tsui, Mr John Mok, Ms Vicky Fung Information Technology and Health Informatics Division, Head Office, Hospital Authority, HKSAR

2 Introduction Need for secondary use of pathology data subset to facilitate data retrieval Support patient care, decision support, data analytics Pathology data Healthcare services Data analytics Support

3 What is a subset? A set whose members are all contained in another set. A subset is a collection of concepts from an edition of. Concept Concept Concept Subset

4 Background 11 anatomical pathology systems in the Hospital Authority Auto-encoding with SNOMED III and local code by matching keywords in the diagnosis result Encoded data for cancer related programs e.g. Cancer registry, cancer case notification system, data analysis Diagnosis Laboratory Encoding

5 Background Localized SNOMED III were lack of maintenance Keywords for diagnosis, localized SNOMED III and local code were consolidated as a corporate SNOMED III list Corporate SNOMED III list to concept mapping Facilitate SNOMED encoding and data retrieval program Corporate SNOMED III list concept

6 Design Definite Suspicious Topography Corporate standard subset ConceptID Hosp A Hosp B Hosp C

7 Corporate SNOMED III list to mapping Hosp A Infiltrating duct carcinoma M Hosp A Duct cell carcinoma M Hosp B Duct adenocarcinoma M Hosp C Ductal carcinoma M Corporate SNOMED III list Terms mapping ConceptID Infiltrating duct carcinoma (morphologic abnormality) concept to corporate SNOMED III list mapping has been endorsed by Anatomical Pathology Working Group in 2015

9 Apply program queries to retrieve terms Program queries M Local code Program queries Local code Terms M Duct cell carcinoma M Duct adenocarcinoma M Infiltrating duct carcinoma

10 Mapping terms with Program queries M Local code Program queries Local code Terms mapping M Duct cell carcinoma M Duct adenocarcinoma M Infiltrating duct carcinoma ConceptID Infiltrating duct carcinoma (morphologic abnormality) Include as a subset member

11 Migrate program queries to subset Program Result data Subset Queries Topography Terms Topography Topography Queries Definite Terms Definite Definite Queries Suspicious Terms Suspicious Suspicious Local code Program queries Local code Terms mapping

13 Retrieval result by subsets is more complete Program queries M Local code Program queries Local code Terms mapping M Duct cell carcinoma M Duct adenocarcinoma M Infiltrating duct carcinoma ConceptID Infiltrating duct carcinoma (morphologic abnormality) M Ductal carcinoma New local terms/ local variable SNOMEDIII

14 Use hierarchy for data analysis and quality assurance Subset Topography Definite Suspicious conceptid Fully specified name Infiltrating duct carcinoma (morphologic abnormality) Infiltrating duct and lobular carcinoma (morphologic abnormality) Lobular carcinoma (morphologic abnormality) Tumor cells, malignant (morphologic abnormality) Descendants of malignant neoplasm? any concepts under the parent concept malignant Neoplasm (Morphology), conceptid , represents a malignant disease

15 Flexible queries by subset Subset Topography Breast Topography Colorectal Definite Carcinoma in situ Topography Breast Definite Pathology data Definite of breast cancer Topography Colorectal Carcinoma in situ Pathology data Carcinoma in situ of colorectal cancer

16 Different localized snomed III queries Hosp A Breast Ca Corporate standard retrieve data in all hospitals control and maintenance Hosp B Breast Ca Corporate Breast Ca subset conceptid Hosp C Breast Ca Hosp A Breast Ca Hosp B Breast Ca Hosp C Breast Ca

17 Using subset for data retrieval Cancer Registry subset Cancer case notification subset Breast cancer subset Colorectal cancer subset Lung cancer subset Corporate SNOMED III List Local terms + Results Pathology data for secondary use

18 Using subset for data retrieval Cancer case notification subset Definite Suspicious Patients pathology reports Definite malignant Ca Suspicious malignant Watermark alert Extra copy

19 Using subset for data retrieval Breast cancer subset Definite Suspicious Patients pathology reports Definite malignant Ca Suspicious malignant Breast Patient listing for cancer case manager Topography Breast

20 Support Conclusion has become the primary key for data retrieval. subset is the corporate standard for data retrieval. Re-use pathology data to support frontline operation and accurate data analysis. Pathology data Healthcare services Data analytics
