1. Study identification
EU PAS Register NumberEUPAS35413
Official titleDevelopment of a Multivariable Model to Predict the Risk of Dose Delays following Chemotherapy
Study title acronym
Study typeObservational study
Brief description of the studyCancer chemotherapy is administered to patients at fixed time points to incorporate a rest period to recover from adverse effects (AEs) and delays to recovery will result in delays to scheduled treatments. These treatment delays occur in over 10% of chemotherapy patients and cause both patient and service inconvenience. The aim of this research is to develop a prediction model to understand those patients most susceptible to dose delays, enabling clinicians to action any mitigation strategies. This study is a retrospective cohort study using chemotherapy prescribing data from 4 UK hospitals to develop and internally validate a risk prediction model. Predictor variables have been identified from the literature. These will be initially analysed by univariable analysis to understand their associations with outcome, dose delays. These variables will enable the development of a multivariable logistic regression model. The model will be tested for performance and internally validated.

15. Data analysis plan
Please provide a brief summary of the analysis method
We will develop risk prediction equations using the whole cohort of patients to predict the risk of a patient receiving a dose delay at cycle 2.
A Multivariable logistic regression model will be used for the analysis as an appropriate method where outcomes are binary and independent variables are continuous, categorical or a combination. Initially, we will fit a full multivariable model containing all variables. Backward elimination will then be used to successively remove non-significant factors with p values of greater than 0.2. Continuous candidate predictors will be retained in their continuous form to avoid statistical power loss.
The performance of the developed model will be summarised in the development datasets using calibration and discrimination. Model calibration determines performance in terms of the agreement between predicted outcome risks and those actually observed. To quantify the degree of optimism, we will undertake in internal validation.
