Artificial intelligence (AI) is increasingly a transforming force in modern healthcare, particularly in the management of chronic diseases where diagnostic accuracy, long-term follow-up, and patient-centered care are paramount. Systematic reviews recognize that AI-driven tools support better clinical decision-making, early diagnosis, and tailored management plans for various chronic disease conditions, including cardiovascular, metabolic, and neurodegenerative diseases (Singareddy et al., 2023) [1]. Such advances, however, introduce important questions around the quality of care and the place of healthcare practitioners, similar to previous evaluations of high-level advanced practice models in the delivery of effective, evidence-based care (McCleery et al., 2014) [2].

Aside from diagnostic accuracy, AI application in healthcare enters human spheres of empathy, trust, and compassion [4]. Studies show that while AI technologies optimize efficiency, they must be well integrated to preserve the humanistic values upon which care is based (Morrow et al., 2023) [3]. Design of technology and human factors that affect provider adoption and use of AI-enabled clinical decision-making support systems also affect their success (Knop et al., 2022) [5]. This is particularly the case in underserved and rural settings where AI-enabled technologies can mitigate healthcare disparities by optimizing access and continuity of care (Osborne et al., 2020) [6]. Conversational AI and virtual assistants are another area of AI application, providing scalable solutions for long-term patient care by way of education, monitoring, and behavior change (Schachner et al., 2020) [7]. Clinicians are enthused but also wary, highlighting the importance of open, clinically valid, and professionally acceptable AI systems (Maassen et al., 2021) [8]. Collectively, these results demonstrate how AI-supported diagnostic trends in chronic disease care are not so much a question of technological progress but ethical incorporation, professional growth, and equitable access.

Study Design

This paper employed a narrative review method to integrate evidence on the application of artificial intelligence (AI) in the diagnosis and management of chronic diseases. The method was employed to integrate evidence from various studies, including systematic reviews, literature reviews, scoping reviews, and surveys, and thus provide a balanced view of AI-enabled diagnostic trends in chronic care.

Data Sources and Search Strategy

A comprehensive search was conducted in the main scholarly databases, including PubMed, Scopus, and Web of Science, focusing on publications in the past decade to ensure the evidence was current. The search terms included "artificial intelligence," "chronic disease," "diagnosis," "clinical decision support," and "digital health." Boolean operators and controlled vocabulary terms (e.g., MeSH) were applied to limit the search and select appropriate literature.

Inclusion and Exclusion Criteria

Studies were considered if they evaluated the use of AI in chronic disease diagnosis, decision support, or patient care. Quantitative and qualitative studies, including systematic reviews, experimental studies, and survey studies, were included. Excluded studies were those which examined only acute conditions, editorial commentaries with no data, and studies published in languages other than English.

Data Extraction and Synthesis

Relevant data from qualified studies were abstracted, such as authorship, publication year, study design, AI applications under scrutiny, and salient outcomes for diagnostic accuracy, patient care, or healthcare provision. The information was then synthesized thematically, categorizing evidence into areas like diagnostic accuracy, human factors, ethical integration, and use in underserved populations. Focus was on making connections between technological trends and clinical relevance in chronic disease management.

Diagnostic Accuracy and Clinical Decision Support

The review identified that systems assisted by AI consistently demonstrated improved diagnostic accuracy in chronic conditions such as diabetes, hypertension, and cardiovascular disease. Machine learning algorithms' predictive performance was superior to conventional diagnosis in risk stratification and early detection. Clinical decision support systems incorporating an integrated AI were particularly effective in assisting physicians in managing complex cases, reducing diagnostic delay, and increasing treatment personalization.

Table 1 provides comparative diagnostic accuracy rates between AI-assisted diagnosis models and traditional clinical methods, with uniform improvement for different chronic conditions.

Human Factors and Provider Adoption

Evidence indicated that provider attitudes, ease of use, and trust in the system were major drivers of the adoption of AI technologies in chronic care. Physicians and nurses reported that transparency, explainability, and clinical workflow adherence determined the extent to which AI systems were adopted. Studies also underscored the importance of balancing technological effectiveness with compassionate care.

Table 2 summarizes provider-reported benefits and drawbacks of AI-supported diagnosis in chronic disease management.

Access and Patient Engagement

AI applications, including conversational agents, were also seen to enhance patient engagement with ongoing monitoring, reminders, and health education. The applications were particularly effective in rural and underserved populations, where it helped in ensuring improved access and continuity of care. Graphic visualizations of adoption rates revealed that patient adoption of conversational AI was higher in regions with limited traditional healthcare infrastructure.

Figure 1 illustrates the rate of AI adoption among different healthcare settings, and Figure 2 illustrates patient satisfaction scores for management tools enabled by AI.

The results of this review show that artificial intelligence is assuming a more central position in chronic disease diagnosis and management, providing quantifiable gains in diagnostic accuracy, patient participation, and access to healthcare. AI-supported models persisted to outperform conventional clinical approaches in predictive power and early identification, especially for diseases like diabetes, hypertension, and cardiovascular disease. These findings are consistent with current studies on the revolutionary potential of AI in improving clinical practice and decision-making across specialities (Alowais et al., 2023) [10]. Precisely, the application of conversational agents and decision support systems demonstrates how AI can enhance—rather than replace—clinical know-how through the optimisation of workflows and more individualized care delivery.

The contrast with existing literature is also supportive of these findings. For instance, AI applications in oncology, specifically head and neck cancer, have demonstrated similar advantages in diagnostic accuracy and risk stratification, pointing out that AI strengths are not limited to one disease domain but generalize across chronic and complex diseases (Mäkitie et al., 2023) [12]. Likewise, AI-based models in the COVID-19 outbreak showed how predictive analytics could inform timely interventions and resource allocation, particularly in low- and middle-income nations, which further strengthened its application in monitoring for chronic illness where system capacity is generally limited (Naseem et al., 2020) [13]. In the management of osteoporosis, orderly development and open reporting of AI instruments are already transforming disease surveillance and prevention planning, part of a larger pattern of clinical dependence on algorithmic intelligence (Gatineau et al., 2024) [14].

Though the advantages are clear, the literature highlights ongoing challenges. Overreliance, explainability, and ethical usage concerns continue in accord with regulatory and safety-oriented analysis observations that warn AI uptake needs to be supplemented by effective control and professional education (Pashkov et al., 2020; Blum et al., 2011) [11, 15]. Similarly, the long-term validity of AI in chronic illness relies on open evaluation models similar to those promoted in evidence-based research efforts like that of Cochrane, wherein reproducibility and methodological soundness are cornerstones (Soll et al., 2020) [9].

Taken together, these findings suggest that AI’s role in chronic illness management is not merely a technological innovation but a paradigm shift in healthcare delivery. Its success will depend on striking a balance between clinical effectiveness and humanistic care, ensuring ethical implementation, and fostering trust among both patients and providers.

Artificial intelligence is gradually transforming the landscape of chronic disease care by improving diagnosis, facilitating clinical decision-making, and enhancing patient participation, especially in resource-constrained environments. Evidence from various fields supports that applications of AI, when responsibly implemented, can supplement medical knowledge and lead to more personalized and equitable care. Yet, sustainable success will depend on close attention to ethical guidelines, openness, and provider credibility to guarantee that technological development is matched with humanistic principles of healthcare. With ongoing development of AI, its successful implementation in chronic care will depend on holding this balance while encouraging close scrutiny and fair distribution
