In association with KQCodes, ARC proudly presents the TechSocial Series. In September, we will be joined by Alasdair Warwick, NIHR Clinical Lecturer at the UCL Institute of Cardiovascular Science and a Medical Retina Fellow at Moorfields Eye Hospital to talk about - CodeMiner and CMQL: turning clinical codelists into transparent, reusable recipes.
A series of FREE, informal TALKS, DISCUSSION and PIZZA! Open to anyone interested in computational research methods, technology and innovation, this series covers a broad range of tools, programs, digital environments & language.
Join us every month at 90 High Holborn
Abstract
Nearly every study using electronic health records starts with a codelist: the set of clinical codes that defines a disease, a drug, or any other variable. Building these lists is slow, error-prone, and rarely reproducible, yet the validity of the entire downstream analysis depends on getting them right.
CodeMiner is a cloud-native platform that facilitates codelist creation. A no-code interface lets clinicians build Boolean queries that are captured as CMQL (CodeMiner Query Language), a set of composable R functions designed to read like a query language. CMQL separates the portable "recipe" from the resolved codes, making every codelist human-readable, auditable, and re-runnable.
This talk covers the design of CMQL, the terminology engine built on DuckDB, and the ongoing migration from a per-user R Shiny prototype to a cloud-native AWS stack (an R Plumber API on Fargate, with DynamoDB and S3), undertaken through the UCL Centre for Digital Innovation accelerator.
About the speaker
Alasdair Warwick is an NIHR Clinical Lecturer at the UCL Institute of Cardiovascular Science and a Medical Retina Fellow at Moorfields Eye Hospital. Alongside his clinical and epidemiological research, he is an R developer with two rOpenSci peer-reviewed CRAN packages, and the creator of CodeMiner. CodeMiner grew out of codemapper, a tool he built during his PhD that now underpins published studies in Nature Communications, JAMA Dermatology, and Eye. He is currently developing CodeMiner into a SaaS platform through the UCL Centre for Digital Innovation Impact Accelerator (in partnership with AWS and UCL ARC).
