Introduction

Sepsis and septic shock represent severe pathological conditions characterized by the systemic response to infection, which can lead to organ dysfunction and high mortality. Early diagnosis and rapid intervention are crucial for improving survival chances. However, sepsis diagnosis is complex due to its nonspecific symptoms and variability in patient responses to infections [1].

Artificial intelligence (AI) and machine learning (ML) provide innovative approaches for the prompt detection of sepsis and septic shock. By examining vast amounts of clinical data, ML algorithms can detect signs and predictors of sepsis more precisely than older methods. Notably, deep learning techniques have been applied to review information from electronic health records (EHR), effectively pinpointing individuals who are at significant risk for sepsis well before symptoms become apparent [2].

Implementing AI in sepsis diagnosis can lead to faster and more precise detection, allowing for early therapeutic interventions that can save lives. Additionally, AI-based systems can assist in personalizing treatment, adapting it to the specific needs of each patient, which can improve clinical outcomes and reduce costs associated with sepsis treatment.

The incorporation of artificial intelligence (AI) into diagnosing and managing sepsis and septic shock represents a considerable advancement, yielding optimistic outcomes for early detection, forecasting, and therapeutic approaches. This literature review delves into the latest advancements and consequences of employing AI in this domain, emphasizing early identification, predictive precision, and the use of algorithms for decision support in medical environments.

The development of AI algorithms for early diagnosis of sepsis in intensive care units is a critical area of research. Yuan et al. (2020) developed an AI algorithm for early sepsis diagnosis in intensive care, highlighting AI’s potential to improve patient outcomes through timely intervention [3]. Similarly, Wu et al. (2021) discussed the benefits of AI in sepsis diagnosis, including early prediction and mortality prediction, emphasizing AI’s role in enhancing clinical decision-making in sepsis management [4].

The role of AI extends beyond diagnosis, including clinical decision support. For example, Goh et al. (2021) presented an AI algorithm that combines structured data and unstructured clinical notes, demonstrating high predictive accuracy for sepsis up to 12 h before onset, which could significantly improve early detection and reduce false positives [5]. Furthermore, Shashikumar et al. (2021) introduced COMPOSER, a deep learning model for early sepsis prediction that flags indeterminate cases instead of making false predictions, providing an actionable early warning system for high-risk patients [6].

The accuracy of AI algorithms in diagnosing early-stage sepsis has been demonstrated through various techniques. For example, Par et al. (2022) showed that algorithms like Multilayer Perceptron and Random Forest can diagnose early-stage sepsis with high precision, especially when connected algorithms are used [7]. Similarly, Dhungana et al. (2019) developed a calculable phenotype for diagnosing sepsis and septic shock in intensive care units using a supervised machine learning method, achieving high sensitivity and specificity [8].

The objective of this research is to analyze the implications of using artificial intelligence in the diagnosis of sepsis/septic shock. Within the analysis of the implications of using artificial intelligence (AI) in the diagnosis of sepsis and septic shock, the research method applied is literature review. This method involves collecting, evaluating, and synthesizing existing research and publications regarding the use of artificial intelligence in the diagnosis of sepsis/septic shock to provide a comprehensive and up-to-date understanding of the topic.

To achieve this, the Google Scholar database was consulted to search for studies on the use of artificial intelligence in diagnosing sepsis and septic shock, resulting in a total of 1130 identified works. To narrow down the dataset, it was decided to examine articles published between 2018 and 2023, resulting in 819 results. Subsequently, the focus was placed on analyzing 10 articles, selected based on specific criteria: they must be complete articles, free from duplications, and have a significant number of citations (Figure 1).

Discussion

A crucial aspect of adopting AI in medicine is trust in the technology. Zhang and Zhang (2023) discuss the ethical aspects and governance of trustworthy medical AI, identifying five factors influencing trust in medical AI: data quality, algorithmic bias, opacity, safety and security, and accountability assignment. The authors propose solutions from ethical, legal, and regulatory perspectives to address these issues and make medical AI more trustworthy [9]. The study showed that AI models can perpetuate or amplify existing biases in training data, leading to unfair or inaccurate recommendations for certain patient groups. Although not directly related to sepsis, the study by Nagendra et al. (2023) on advancements in diagnosing thyroid cancer with AI demonstrates significant improvements in sensitivity and specificity compared to traditional diagnostic methods, highlighting AI’s potential to revolutionize diagnosis in various areas of medicine [10]. Date et al. (2023) explore the potential of machine learning and AI to improve diagnosis and treatment in health, highlighting challenges such as data quality, interpretability, execution, generalizability, data protection, and legal compliance. These challenges must be addressed for the efficient implementation and acceptance of AI technologies in the health sector [11].

The research conducted by Ying et al. (2021) investigates the application of an artificial neural network algorithm, enhanced with pulse-coupled neural network (PCNN) techniques, for diagnosing severe sepsis complicated by acute kidney injury (AKI), utilizing data from ultrasonographic images [12]. The algorithm showed promising results in enhancing the information from ultrasonographic images, and the change in renal resistive index (RRI) measured through ultrasonographic images is associated with AKI [12]. The study concluded that there is a risk that doctors may rely too much on AI algorithm recommendations, neglecting detailed clinical evaluation and professional judgment. However, using patient data to train AI models raises concerns about privacy and data security.

Ou et al. (2022) uses a machine learning-based approach to predict future risks of rehospitalization with acute kidney injury (AKI) in sepsis survivors. Machine learning models, especially LGBM and GBDT models, have shown promise in predicting AKI rehospitalization, with the most important five features being C-reactive protein, white blood cell count, the use of inotropes, blood urea nitrogen, and the use of diuretics [13].

Studies have demonstrated AI’s ability to rapidly analyze large volumes of clinical data, identifying early signs of sepsis with greater accuracy and speed than traditional methods. Rajendran et al. (2018) highlighted the utility of the shock index as a marker for mortality in pediatric sepsis, underlining the potential of data analysis through AI [14].

Integrating AI into clinical practices for sepsis management offers a multidimensional approach to patient care. Mollura et al. (2021) proposed an AI-based intensive care unit monitoring system that uses physiological waveforms to identify sepsis within the first hour of ICU admission, highlighting AI’s potential to assist clinicians in early decision-making processes [15]. This approach highlights the importance of real-time data analysis in critical care settings, where early intervention can significantly affect outcomes. AI’s role extends to improving diagnostic tools, such as ultrasound and biomarker analysis. Tullo et al. (2023) discussed the benefits of ultrasound in diagnosing and treating sepsis and septic shock, suggesting that AI could further enhance the utility of ultrasound through more accurate characterizations and therapy optimizations [16].

Similarly, Choo et al. (2020) explored the utility of ischemia-modified albumin as a biomarker in the diagnosis of sepsis, indicating that AI could improve predictive power by integrating biomarker data with clinical observations [17]. The prognostic capabilities of AI are also noteworthy. Ruiz-Sanmartin et al. (2022) characterized a proteomic profile associated with organ dysfunction and mortality in sepsis patients using omics techniques, providing a basis for AI algorithms to predict patient outcomes and accordingly tailor treatments [18].

Similarly, Spoto et al. (2019) demonstrated the combined use of procalcitonin and MR-proadrenomedullin for diagnosing sepsis and stratifying mortality risk, showing how AI can use biomarker data for improved clinical decision-making [19]. AI represents a promising frontier in the fight against sepsis, offering new perspectives and innovative solutions for a persistent medical challenge. However, realizing its full potential will require a balanced approach that weighs innovation against caution, ensuring that the benefits of technology are accessible and positively impact patient care in an ethical and sustainable manner. Although the benefits of artificial intelligence in managing sepsis are evident, challenges remain in its implementation. These include concerns about data privacy, the need for standardized datasets for training algorithms, and ensuring that AI systems are interpretable and explainable to healthcare providers. Overcoming these challenges requires ongoing research, interdisciplinary collaboration, and policy development to ensure that AI tools are ethical, efficient, and seamlessly integrated into healthcare systems.

Conclusions

Integrating AI with diagnostic tools such as ultrasound and biomarker analysis can further refine diagnosis and treatment plans. This has demonstrated how AI can enhance the utility of these tools, offering more precise and personalized therapeutic options.

AI’s ability to predict outcomes and optimize treatment strategies underscores its value in prognosis and the personalization of care, which can lead to improved survival rates and reduced healthcare costs. In our examination of ten articles, it was discovered that AI possesses the potential to significantly alter the diagnosis and treatment of sepsis. It provides methods for swiftly and precisely detecting patients at risk, alongside customizing treatment strategies.

The studies highlighted, from the use of the shock index as a prognostic marker to the prediction of rehospitalization with AKI in sepsis survivors, illustrate the diversity of AI applications and its contribution to improving patient outcomes. AI enhances the clinical decision-making process by analyzing intricate clinical data and producing insightful information. This enables faster and better-informed actions that can lower mortality rates and elevate the standard of care.

Regarding implementation challenges, the risk of excessive reliance on algorithmic recommendations and the presence of bias in AI models are major concerns that require ongoing attention and concerted efforts to minimize their impact on clinical decisions.

Protecting patient data and ensuring an ethical implementation of AI represent fundamental challenges that require robust legal and regulatory frameworks, as well as advanced technological solutions for data security. Despite promising developments, the implementation of AI in sepsis care faces challenges, including data privacy, the need for standardized and interpretable algorithms, and integration into existing clinical workflows. Addressing these issues requires concerted efforts from researchers, clinicians, and policymakers to ensure that AI tools are ethical, efficient, and seamlessly integrated into healthcare systems. AI holds the promise of transforming sepsis care through improved early detection, diagnostic accuracy, support for clinical decisions, and personalized treatment strategies.

However, realizing its full potential requires overcoming existing challenges and ensuring that AI tools are designed and implemented in ways that complement and enhance clinical reasoning and patient care. As the field advances, ongoing research, interdisciplinary collaboration, and clinical validation are essential to harness the power of artificial intelligence in the fight against sepsis and septic shock, ultimately leading to better patient outcomes and more efficient healthcare delivery.

Regarding future directions, the efficient and responsible integration of AI in medicine will depend on close collaboration between engineers, doctors, researchers, and policymakers to develop solutions that are technologically advanced, clinically relevant, and ethically sound. Developing AI competencies for healthcare professionals and improving patients’ digital literacy are essential for successfully navigating the new era of digital medicine. Investments in fundamental and applied research are crucial for overcoming the current limitations of AI and exploring new horizons in the diagnosis and treatment of sepsis.
