Computerized clinical decision support systems, known as CDSS, signify a profound transformation in modern healthcare. These systems are designed to enhance and support clinicians in their intricate decision-making processes. Since their initial adoption in the 1980s, CDSS has undergone rapid evolution. They are now predominantly integrated into electronic medical records and various computerized clinical workflows, facilitated by the increasing global adoption of advanced electronic medical records. Even so, despite these advancements, several uncertainties persist regarding the impact of CDSS on healthcare providers, patient outcomes, and associated costs. While the past decades have witnessed numerous success stories in CDSS implementation, significant setbacks have also underscored the inherent risks. In this paper, we present a state-of-the-art overview of the application of clinical decision support systems in medicine, encompassing various types, current use cases with established effectiveness, common challenges, and potential drawbacks.
What is a Clinical Decision Support System?
A clinical decision support system (CDSS) is an application designed to analyze data with the aim of aiding healthcare providers in making informed decisions and enhancing patient care. It is a specialized form of the broader decision support system (DSS) commonly employed in business management. The primary focus of a CDSS is to leverage knowledge management for providing clinical guidance based on various facets of patient-related information. These systems facilitate integrated workflows, offer real-time assistance during care delivery, and provide recommendations for care plans.
In the context of clinical decision support systems, data mining is often employed to examine a patient's medical history alongside pertinent clinical research. This analysis aids in anticipating potential events, such as drug interactions or the identification of disease symptoms.

CDSSs have been categorized into various types and classifications, considering intervention timing and whether their delivery is active or passive. These systems are commonly classified into two main categories: knowledge-based and non-knowledge-based.
In knowledge-based CDSS, rules are formulated, typically in the form of IF-THEN statements. The system retrieves relevant data, assesses these rules, and generates an appropriate action or output. These rules can be established based on literature-derived, practice-based, or patient-specific evidence.
On the other hand, non-knowledge-based CDSS still rely on data sources, but they leverage technologies such as artificial intelligence (AI), machine learning (ML), or statistical pattern recognition to make decisions, rather than being explicitly programmed with expert medical knowledge. This category represents a rapidly expanding use case for AI in medicine, although it comes with challenges. These challenges include understanding the rationale behind AI-generated recommendations (commonly referred to as "black boxes") and issues related to data availability. As of now, non-knowledge-based CDSS has yet to achieve widespread implementation. Both knowledge-based and non-knowledge-based CDSS share common components, albeit with subtle distinctions.
The Purpose of Clinical Decision Support Systems (CDSS)
The primary objective of a clinical decision support system is to aid healthcare providers in analyzing patient data and utilizing this information to assist in making accurate diagnoses. CDSSs offer valuable information to clinicians and primary care providers, with the overarching goal of enhancing the quality of care provided to their patients.
CDSS tools serve various functions, such as providing reminders for preventive care, issuing alerts regarding potential drug interactions that could pose risks, and notifying clinicians about scheduled redundant tests for their patients. By doing so, using a CDSS can lead to cost reduction and increased operational efficiency within healthcare settings.
Furthermore, some healthcare providers deploy CDSSs to identify cases where patients may have received incorrect diagnoses or been prescribed incorrect medication dosages. Such errors are flagged and added to problem lists, and this data is incorporated into population health management (PHM) reports. These reports, in turn, serve as the foundation for quality improvement initiatives in healthcare.
What Advantages Does Clinical Decision Support Offer?
When evaluating clinical support decision systems, it's crucial to consider both the pros and cons. Here are some benefits associated with clinical decision support systems (CDSS):
- Minimization of Medication Errors: CDSS helps reduce the likelihood of medication errors by providing timely and accurate information about drug interactions, dosages, and contraindications.
- Centralized Information Repository: Acting as a central repository, CDSS consolidates all relevant information, ensuring healthcare professionals have comprehensive data at their fingertips.
- Reduced Risks of Misdiagnosis: By offering insights and recommendations based on available data, CDSS contributes to lowering the risks of misdiagnosis, and improving diagnostic accuracy.
- Consistent Information Delivery: CDSS ensures the consistent and reliable delivery of information to the entire healthcare team, promoting standardized practices and enhancing collaboration.
- Enhanced Efficiency: Healthcare practitioners benefit from increased efficiency as CDSS streamlines decision-making processes, allowing for quicker and more informed responses.
- Improved Healthcare Service Quality: The use of CDSS contributes to the overall improvement of healthcare services by supporting evidence-based decision-making and adherence to best practices.
While these advantages are notable, it's essential to acknowledge the challenges associated with implementing CDSS. Integration into complex clinical workflows, potential interoperability issues with other software, and the constant influx of new medical data that may not be promptly incorporated pose significant hurdles. Additionally, the substantial volume of data integrated into existing systems may strain application and infrastructure maintenance. Understanding both the benefits and challenges is crucial for making informed decisions about the adoption of clinical decision support systems.
