Abstract

Complex algorithms and prediction models are increasingly being developed, investigated and applied for clinical use in medical laboratories and beyond. Proper algorithmic functioning in a clinical setting is of the utmost importance to ensure patient safety. Recently, a tumor marker-based, longitudinal, machine learning model (mSTOP) was developed to predict which non-small cell lung cancer patients would not respond to (chemo-)immunotherapy early in the treatment process. This model was then clinically implemented in a hospital setting for which ICT infrastructure was developed to allow for the model's automated and real-time application. To ensure the appropriate functioning of the ICT infrastructure and the algorithm, a quality control (QC) strategy was developed and executed similarly to normal internal QC for clinical tests performed routinely in the laboratory. This quality control strategy entitled; scenario-based multiparametric quality control (MPQC) is based on the input and output values of different pre-specified scenarios obtained from the original clinical validation study. This perspective aims to justify and elucidate the concept of this QC strategy for quality control of complex algorithms operated in a clinical setting.
