Introduction
The combination of patient-derived data, such as genomics and lifestyle information, with patient registries
and databases holds immense potential for improving medical care. One such potential lies in computer-
based personalized models capable of providing precise, patient specific, predictions. Predictive and
prognostic models hold great potential to support clinical decision making in personalized medicine
[1]
and could ultimately facilitate a paradigm shift to a more personalized form of treatment. Various
computational models (see 3.10) have been devised to assist with the decision-making process.
Prognostic models are mathematical tools that relate a person's current characteristics and individual risk
factors to the likelihood of a particular future outcome or disease course. Examples include estimating the
probability of disease progression in an already ill patient or predicting whether an individual is likely to
develop a disease in the future based on its own risk profile (risk stratification). Prognostic models can
incorporate one or many current characteristics (multivariable). When validated, these models provide
clinicians with objective estimates of the probability of treatment response, possible complications or
quality-of-life-evolution that complements other clinical information.
Predictive modelling, on the other hand, uses available data to forecast likely future responses and effects
of a specific treatment or intervention. This can be used to identify patients at high risk for adverse events
(such as hospital re-admission) as well as those with a high probability of responding positively to a specific
treatment. By providing individualized information on prognosis and potential response to therapy,
predictive models are increasingly valuable tools for personalized, patient-centred medicine. Examples
include identifying patients at high risk of readmission after a particular treatment or in silico modelling of
[1]
therapy effects in specific patients or cohorts .
The assessment of computational models (e.g., statistical models, mechanistic models, machine learning
and deep learning models) is done in the context of clinically driven research studies. Nevertheless, these
studies are complex and challenging both from the clinical and the technological side. For complex diseases,
such as certain cancer types, very often, only a few prognostic bioprofiles and even fewer, if any, multiscale
prognostic models (models that include biological data ranging from the molecular scale to the entire organs
and human organism, such as multi-scale models) are available on which to base personalized treatment
decisions.
In most cases, available models lack robust validation in which: a) the predicted risks are compared to the
actual observed outcomes in a patient population, and b) the model is validated in patient cohorts different
[2]
from those used for developing the model and quality controls. These controls include the internal and
external validation of the computational models. Internal validation is needed during the model development
to quantify any optimism in the predictive performance whereas external validation is needed for model
[3]
generalization and require new data sets. This causes a gap where important information becomes
unavailable for optimal treatment decision making.
More prognostic predictions than those available from current clinical guidelines-based systems (such as
Tumor-Lymphnode-Metastasis staging for cancer) are often needed to implement the first-line treatment that
maximizes the therapeutic result and minimizes the impacts of therapy in terms of functional impairment
and toxicity. Providing clinicians with the prognostic and predictive models supporting clinical decisions
and providing all the necessary information to tailor treatment and care delivery pathways to each patient
during their usual practice, in contrast to the current "one-size-fits-all approach", is an unmet need.
[4][5][6]
The development of clinical decision support system (CDSS) could be achieved by combining
[5] [6] [7]
"traditional" statistical models with artificial intelligence (AI) algorithms driven by the manifold
[1]
of health and other person-related data (big data) collected from patients, as well as the integration of
big data results with the statistical models. Moreover, it is necessary to validate the existing and newly
developed models in different individuals and several populations and either adjust the person-related
[1]
models accordingly or develop generally applicable models. This process will create a virtuous cycle of
learning between research and clinical practice, through the mutual feeding of external population data and
patient-specific clinical data.
Improving the clinical decision process by implementing a prognostic system based on personalized
computational models that increases the accuracy and reinforcement of a multidisciplinary decision-making
would help define the optimal treatment for a particular patient. In addition, uncovering patient-specific and

v
population-related patterns can improve care and pave the way for better-tailored treatment guidelines, by
assessing the importance (scoring) of new prognostic markers for outcome prediction, finally improving the
patient's quality of life.

4 Fundamental requirements
4.1 General
Clinical decision support systems (CDSS) are software tools including algorithms that link together and
analyse multisource and multiscale patients’ data from Electronic Health Records (EHRs) including
laboratory data, patient history, risk factors, behavioural data and socio-economic indicators if available,
multi-omics (e.g. genomics, transcriptomics, radiomics, metabolomics, etc.), pathology, and imaging data,
with available multiscale prognostic models and graphical visualization tools that assist healthcare providers
in clinical decisions. CDSS may also include population-based epidemiologic, behavioural and environmental
data. CDSS aid physicians in integrating almost all-available information to allow the best possible treatment
and therapy decisions. To support healthcare professionals in their daily practice, aggregated knowledge
shall be displayed in user-friendly formats so that physicians, non-technical laboratory personnel, nurses,
data/research coordinators, and end-users can enter data, access information, and understand the output
in the clinical setting. CDSS are tools that incorporate established clinical knowledge and updated patient
information to enhance patient care; they encompass an array of strategies supporting a variety of topics.
[9]
Patient data require sequential processing to reach correct clinical conclusions, and then to become
knowledge. EHR-based CDSS promise to translate clinical data into knowledge that can be readily used by
physicians for decision-making and that can decrease the incidence of errors.
The system should intrinsically allow collaborative analysis, enabling multiple users to work on the same
research objects and studies, reinforcing multidisciplinary decision-making. Insights from different
collaborators shall be visible to all other cooperation partners to be used, for instance, for other studies
focused on different cancer types. Users shall be able to define their role and activities assignments, being
managed for the principal investigator of each study.
Data collection functionality shall be readily available when new data is collected, following the Clinical
Record Forms (CRF), defined in the data layer. Data quality reports shall also be accessible from this
functionality, and data correction shall be allowed. The user should access the data by selecting it following
the standard nomenclature defined in the data layer. Data queries should be delivered through an
understandable and easy-to-use interface, enabling the management of extensive heterogeneous data. The

users shall be able to export the data and visualize it. For each individual patient’s EHR, direct visualization
and a descriptive way to allow first data exploration should be provided.
Population data or other public data should be delivered - whenever available - to provide context and
reference indicators. Existing preliminary analysis, evidence criteria and researchers’ insights shall be
available when accessing a particular manuscript.
4.2 Standardization requirements for clinically driven research studies
4.2.1 General
Scientific managers and clinical trials responsible are experiencing increasing regulations such as Good
clinical practice (GCP) regulations or some European and international guidelines and directives. Still,
limited discussions have been conducted to formalize and define the adequate quality of a standard
operating procedure (SOP) system.
Since data represent a key aspect for sound and trustable research in clinical trials and digital health studies,
data sharing and (re)use procedures are fundamental. Consequently, a high level of rigorous standards
and semantic specificity is required not just for humans, but also for computational analysis. In particular,
standardization can improve clinical research through increased data quality, better data integration and
reusability, facilitation of data exchange with collaborating institutions, increased use of software tools,
improvements in team communication, and simplification of regulatory reviews and audits. Similarly, trial
execution procedures, processes, documentation, and reporting shall be ruled by well-defined SOPs relying
on acknowledged standards and guidelines.
The user should not need to search for relevant standards or guidelines to select the appropriate ones,
as this is time-consuming and error prone. On the contrary, the system shall propose the necessary
information and the appropriate SOPs to guide the research and elaborate on the reporting results. Annex A
includes a map of the existing guidelines to report clinical trial results when dealing with personalized
systems and computational models. Considering these guidelines in Annex A and the Good Clinical Practice
recommendations, Figure 1 represents the clinical research process. First, a CDSS should collect from the
clinical researchers and provide the rational, goals and setting of the study. If the study is interventional,
then details on the intervention (whether it is a drug administration or a computational model-driven
intervention) shall be provided by the clinical researchers. Then, in all studies, clinical researchers and their
teams should perform and document carefully data collection and data management processes to make sure
that the data quality is sufficient to allow performing modelling (either standard statistics or computational
models) and ensure interpretability of the results.
Limitations of the clinical research study shall be reported and taken into account, including:
a) populations representativeness: inclusion criteria limiting the population of interest to specific
subgroups (e.g., non-considering gender/ethnicity/etc. in the study as compared to real-world prevalence
fractions);
b) selection bias: systematic differences between baseline characteristics of the compared groups;
c) performance bias: systematic differences between groups in the care that is provided, or in exposure to
factors other than the interventions of interest;
d) detection bias: systematic differences between groups in how outcomes are determined;
e) attrition bias: systematic differences between groups in withdrawals from a study.
Methodologies and guidelines exist to address such biases, which shall be implemented and reported with
the study results.
Ethical and legal considerations applied in the trial shall also be considered, addressed, and reported by the
study team as they can influence study subject inclusion criteria and/or data collection.

4.2.3 Basic requirements and conditions for in silico models for clinical decision support systems
In silico models and associated CDSS shall be flexible and adaptable to the specific clinical care workflows to
which they are applied.
In silico models shall be conceived in a way to be easily integrated as part of the IT-supported care delivery,
that is making them act as useful and time-saving tools connected to the usual practice
In silico models’ simulations/predictions shall be sufficiently transparent (e.g., through supporting data,
description of the data analysis processes and data pipelines, data selection criteria, biases, confidence
intervals and other evaluation parameters) so that they can be discussed among physicians and also with
patients.
[10][11][12][13]
In silico models shall be developed considering usability aspects, including flexibility and
efficiency of use, user-friendly and understandable interfaces. Usability assessment methods for CDSS
[11] [14]
Models are published , .
4.2.4 Defining the research project processes and project management SOPs (RPPM) involving IT
systems for personalized medicine, clinical decisions and in silico modelling
Defining research project processes and project management procedures (RPPM) involves establishing a
structured framework to establish policies, plans, operational procedures and workflows assuring the
fulfilment of the project objectives, the execution of the associated trials (if any) and the quality of the results
through accurate planning, monitoring, risk assessment, reporting of deviations and recovery of all activities
and standard operating procedures (SOPs) from the very start of the study throughout its implementation
and continuous monitoring. The workflow for RPPM management and monitoring is illustrated in Figure 2.
Figure 2 — Workflow of RPPM
Specific SOPs shall rule the different activities of a research study. SOPs shall support physicians in the
effortless design and reporting of clinical trial results, providing a clinical research group with clear roles,
responsibilities, and processes to ensure conformance, accuracy, and timeliness of data.
SOPs shall ensure matching in silico modelling vs. clinical guidelines for treatment decision and
administration and considering treatment side effects.
4.2.5 Quality of clinical studies involving models and AI
The quality of a study and the trustworthiness of its findings, starts at the design phase. The study protocol
shall contain all elements of the study design, sufficient for independent groups to carry out the study and
expect replicability. Guidance for recommended items to include in a trial protocol are provided by the
[8] [15]
SPIRIT Statement and its SPIRIT-AI extension and the CONSORT guidelines and their CONSORT-AI
[16]
checklist extension .
In case these guidelines do not cover specific aspects of the study, other guidelines such as EQUATOR
[17] [36]
guideline (e.g., Standards for Reporting of Diagnostic Accuracy Studies (STARD ) for diagnostic
accuracy studies) shall be used.
An early-stage clinical AI evaluation shall consider the potential for iterative modification of the interventions
and the characteristics and expertise (e.g. training) of the operators performing them. Aspects such as
training of medical and clinical staff involved in the use and interpretation of results from clinical decision
support systems are fundamental for proper clinical evaluation and for appropriate and safe use of such
complex tools for personalized medicine.

The DECIDE-AI checklist for early clinical evaluation of AI-supported CDSS and results reporting shall
be adopted. All items in the checklist shall be fulfilled, included in the study master file and used for study
reporting, early evaluation and clinical assessment.
