Abstract
Background: Artificial Intelligence (AI) is increasingly being used in the medicine administration and drug–drug interaction (DDI) screening domain in healthcare. However, its reliability in comparison with the pharmacist review is unknown. This systematic review aimed to compare the effectiveness of DDI alerts generated by AI to DDI alerts generated by pharmacists.
Methodology: This review was done in accordance with PRISMA 2020 guidelines and registered with PROSPERO (CRD420251153581). The publications since 2022 were obtained from PubMed, Embase, Scopus, Web of Science, Cochrane Library, IEEE Xplore, and arXiv. The Mixed Methods Appraisal Tool (MMAT) 2018 was used to evaluate the quality of the studies.
Results: Fourteen studies of AI systems like ChatGPT, Gemini, Bing AI, and Claude were selected. AI models performed well in general drug information retrieval and were found to have significant shortcomings when it comes to clinical DDI screening. Low accuracy, inconsistent responses, severity and onset not assessed and clinically important interaction not included were common problems. Pharmacist review and validated databases like Lexicomp and Micromedex were more reliable to assess DDI.
Conclusion: AI systems can provide support for drug information and may be suitable but are currently not sufficient for autonomous drug information screening. However, pharmacist oversight will remain essential to patient safety, and additional studies are required to develop customizable AI systems for pharmacies that incorporate trusted clinical decision support tools.
Keywords: Artificial intelligence, clinical decision support, clinical pharmacy, drug-drug interactions, pharmacist, systematic review.
INTRODUCTION
The safe and effective use of medications represents a fundamental cornerstone of modern healthcare systems worldwide, yet it remains an increasingly formidable challenge in an era of unprecedented therapeutic complexity1. This complexity is determined by factors including polypharmacy, aging population, and the introduction of important biological therapies, all of which increase the risk of drug interactions and adverse events2. Landmark studies from the Institute of medicine established the medical errors that are leading to cause of death, this finding that remains tragically relevant today3. Worldwide, medication errors and adverse drug reactions are represent as substantial public health burden. Lamdmark studies indicates the account for approximately 5-8% of all hospital admissions4, with more recent analyses evaluate the associated annual costs in United States alone exceed as $40 billion5. This complexity of modern pharma-cotherapy that continues to increase with the introduction of new molecular substance, biological therapies, and specialized medications with the narrow therapeutic indices, further complicating the medi-cation safety landscape6. This is the evidenced by regulatory data showing as steady rise for the approval of complex specialty drugs, which require sophisticated management strategies to ensure the safe and effective use7. Between medication safety concerns and preventable harm stemming from drug-drug intera-ctions (DDIs) represent a particularly significant clinical and economic burden that contributing the substantially to patient morbidity, mortality, and avoid hospitalization worldwide8.
The evolution of drug interaction screening has followed an interesting pace through modern medical history, review broader technology and scientific advancement9. In the early to mid-20th century, DDI knowledge occupy primarily in the expertise of seasoned clinicians and pharmacists who relies on personal experience, limited case reports, and emerge pharmacological principles for identify the potential interactions10. This era was specifying by discovery of interactions and typically identify only after adverse events is occurred in patients11. The discovery of thioridazine and quinidine’s QT-prolonged effects serve as a classic example of this model, where the cardiotoxic risk was recognized after fatal outcomes were reportes in the literature12. The turn of the millennial shows exponential growth in computing power and the exposure of the internet, facilitates the development of more refined databases such as Micromedex and Lexicomp that could be updated by more frequently and accessed more readily13. This period also reflects the incorporation of screening tools into electronic health records (EHRs), enabling real time interventions while simultaneously introducing challenges such as alert fatigue excessive14.
Landmark studies have shown that clinicians may override 90% of drug safety alerts significantly reducing their effectiveness15. This historical evolution of DDI management reflects an ongoing effort to balance comprehensive screening with clinical usuability, a challenge that continues to persist as new technologies emerge16. For decades, the primary defense against DDIs has relied on the advance expertise of clinical pharmacists supported by integrated clinical decision supported system (CDSS) together forming a multi-layer safety network17. These healthcare professionals provide an vital cognitive layer, going beyond automated alerts to interpret the risks within the full context of a patient’s unique clinical profile including comorbidities, organ functions, genetic factors, concurrent therapies, and therapeutic goals as defines by their standards of practice (“Standards of Practice for Clinical Pharmacists,” 2014) 18.
The pharmacist's role in clinical practice also includes DDI, which requires a number of specific skills or knowledge19. They have detailed pharmacological knowledge of interaction mechanisms, and they under-stand the difference between pharmacokinetic and pharmacodynamic interactions, which affect the absorption, distribution, metabolism and excretion of the drugs and which affect the action of the drugs at receptor sites, respectively20. Secondly, they use their clinical judgment to evaluate if proposed interactions are relevant, depending on the patient's characteristics (age, renal and hepatic function, genetic polymorphism and disease states)21. Third, they integrate the practical knowledge of what medicines are available in the formularies, as well as the costs of alternative therapies recommended by their physicians22. This multi-dimensional expertise represents the termination of extensive education, training, and clinical experience that cannot be readily reduced to algorithmic processes that supports most clinical decision support systems23. This expert judgment is consistently guide by gold-standard, pharmacist-validated database such as Lexicomp® and Micromedex®, which serve as the reliable, evidence-based sources for DDI information and are recognized the primary source for clinical decision support24.
These comprehensive resources are carefully developed and continuous updated by teams of clinical pharmacists, physicians, and drug information specia-lists who systematically review primary litera-ture, case reports, and pharmacological data to generate the evidence-based recommendations24. This develop-ment of these resources involves standardized evidence graded-systems, ongoing literature surveillance, and formalized review procedures to ensure the information remains both comprehensive and accurate25. The integration of human expertise with validated technology constitute the current ‘pharmacist standard’, severing as the essential benchmark against which any new innovation must be rigorously evaluated26. This is an example of a cooperative model that brings together the strengths of people and technology in a complementary way for safety27. It combines the computational power and broad coverage of databases with the clinical judgment and contextual understanding of the experienced pharmacists28. This partnership has proven highly effective in avert significant medication-related harm, with their systematic reviews exhibit that pharmacist intervention significantly reduces the adverse drug event29. However, it is remain limited by resource restraint as the pharmacist availability cannot always match to the volume of medication requires review, creating a gap between the ideal and practical application of that standard30.
In the context of pharmacy practice, this technology theoretically offer a several advantages over traditional information sources: 24/7 availability, rapid processing of complex questions, ability to synthesize information from the multiple sources; and the capacity is explain to the concepts in various levels of complexity suitable to different users (patient vs. professionals)30. These characteristics suggest to the potential for serving as both clinical decision support tools for their healthcare professionals and educational resources for patients31. Collectively, these studies suggest that LLMs may hold valuable applications in domain requiring rapid information retrieval and composite, particularly for educational purposes or as initial screening tools when used with human mistake, a cautious approach strongly advocated for by conveners in the field32.
The collective evidence paints a regarding picture regarding the preparation of LLMs for DDI screening. These models also shows a critical “contextual blindness”, failing to integrate the patient-specific variables required for personalized risk assessment, which sharply limits to their clinical utility33. The literature, however, remains fractured and methodo-logically diverse. Consequently, a specific and urgent gap exists: there is no systematic a quantitative synthesis that resolves these contraindications by rigorously comparing AI performance to the steadfast benchmark of pharmacist expertise. This present review seeks to fill this gap by offering an evidence based evolution to inform the future of AI in medication safety.
MATERIALS AND METHODS
Study design
The Preferred Reporting Items for Systematic reviews and meta analysis (PRISMA) 2020 guidelines were followed in this systematic review. The study protocol was registered in the international prospective register of systematic reviews (PROSPERO) (registration number: CRD420251153581) before the study commenced there by reducing reporting bias and safeguarding the methodological rigor of the review.
Search strategy
To investigate coverage a systematic search was performed, across the following electronic databases: PubMed/MEDLINE, Embase, Scopus, Web of Science, Cochrane Library, IEEE Xplore, and arXiv (both clinical and technological databases). A combination of controlled vocabulary terms and free-text terms were used in the search strategy, which were associated with artificial intelligence, drug-drug interactions and pharmacist standards. Boolean operators (AND, OR) and proximity commands were employed to get the best of both world's – comprehensive coverage and relevant results. Only articles from January 2022 or newer were searched, to ensure that this covers the latest developments in the field of advanced generative AI.
Data extraction
Standardized form was used in a pilot test to extract the data to ensure uniformity and thoroughness of the data. The authors, publication year, country of origin were extracted from the characteristics of the study, the complete details of artificial intelligence specifications (version of the model, access details), methodological parameters (sample characteristics, study design), reference standards specifications, and the complete outcome data (all reported performance metrics and qualitative findings) were extracted. The extraction process was carried out by two independent reviewers with any discrepancies being resolved by consensus.
Quality assessment
The quality of the methodological framework of the studies contained was determined with the use of the Mixed Methods Appraisal Tool (MMAT) version 2018. The tool was selected due to the applicability that had been developed to the different study methods anticipated in this review that include quantitative descriptive, non-randomized, and mixed methods designs. The MMAT enabled systematic evaluation of five critical methodological qualities of any type of studies, such as elements of sampling approach, suitability of measurements and analysis of data. This was used by two independent research reviewers for each study, and in the event of differing opinions, consensus was reached. The results of this quality analysis were directly applied to interpret the results and the determination of the overall confidence of the synthesized evidence.
RESULTS
A flow diagram of the process of how the studies were selected for this systematic review is shown in Figure 1 (PRISMA). A total of 2036 records were identified by using the database searching method, namely Science Direct, Scopus, Web of Science, PubMed, Google Scholar, ProQuest, and the Directory of Open Access Journals (DOAJ) with 320, 585, 452, 348, 180, 141, and 100 records respectively. Of the 1,296 studies remaining after 713 duplicates and 27 renounced studies were removed, 174 were excluded due to screening failures. Of the 1,296 studies that were left after removing 713 duplicate studies and 27 renounced studies, 174 were excluded because of screening failures. After screening for titles and abstracts, 1180 records were excluded.
116 studies were identified for retrieval and 14 studies were not retrieved (9 conference papers and 5 case papers). An additional 102 studies were evaluated for eligibility. In the full-text assessment, 88 studies were excluded on various reasons, including non-AI generated studies (n=26), absence of pharmacist com-parators (n=13), wrong population or setting (n=18), insufficient empirical data (n=15), editorial/protocol/ review articles (n=7), irrelevant outcomes (n=7), duplicate publications (n=1), and unavailable full texts (n=1). Finally, the systematic review included 14 studies.
Characteristics of the study
The systematic review relies on 14 studies that reflect a worldwide research project and 4 continents, with developed and developing systems having a very strong contribution. The geographical spread shows that there is a focused research interest in the United States (3 studies), but the country shows a high level of international involvement by countries such as Saudi Arabia, Nepal, Iraq, Germany, Austria, Jordan, China, the Netherlands, and multi-national partnerships. This popularity highlights the universal fact of the potential of AI to change medication safety practices in diverse healthcare settings and resource environments.
Temporally, the studies included are representative of the fast-changing nature of this field, with 2023-2025 publications. The increased focus in the studies, mostly on the 2024-2025 period (9 out of 14 studies), reflects the growing research interest that coincided with the emergence of powerful Large Language Models (LLMs) in the public domain. This temporal scope underscores the nature of the present systematic review, which incorporates the most recent evidence within the context of rapidly evolving technologies.
The reviewed studies offer a comprehensive overview of the current AI ecosystem as applied to healthcare solutions.Large language models dominate this technology landscape with open AI ChatGPT varia-tions (particularly GPT-3.4,GPT-4 andGPT-4o) emer-ging as the most widely tested platforms 10 out 14 studies utilize them. The study represents the competitive market of AI by conducting parallel evaluations of Bard/Gemini, Bing AI, and Claude models of Google, Microsoft, and Anthropic.
One of the most useful contributions is made by the studies which performed comparative analysis of several AI systems at the same time. A particularly interesting study tested eight different AI platforms including regional specialists (ERNIE Bot, Doubao) and international leaders (GPT-4o, Gemini-1.5-Pro, Claude-3.5-Sonnet), which allows relevant conclusions about performance differences between different architectural strategies and training methods. Such a comparative method makes a great contribution to our knowledge of the comparative advantages and restric-tions of the existing AI environment.
The development of model capabilities can be tracked through the chronological development of research, with subsequent research adopting more developed versions (GPT-4, GPT-4o) having significant empirical performance improvements over previous ones.
Nonetheless, one of the major methodological issues that can be identified in a number of studies consists of the inability to indicate the version of AI that was tested, which is a serious gap in the area of reproduci-bility because the performance of the model iterations varies significantly. The studies included are quite diverse in terms of methodological approaches, as they use different methods to answer the main research question of AI competency in DDI screening. Cross-sectional analysis (8 studies) is the most common research design and in this case AI performance is compared to reference standards at one time. Comparative diagnostic accuracy studies, retrospective cohort studies and case-based evaluations complement this approach.
The unit of analysis can differ quite widely in dependence on the study, as it is associated with various possible implementation scenarios:
Drug-pair studies (as many as 255 drug pairs) allow the knowledge breadth of DDI to be evaluated systematically. Problems by simulated clinical scenarios (70-80 inquiries) are used to determine practical problem solving skills. Studies that use actual or simulated patient situations (30-414 patients) are used to assess performance in clinical settings of relevance. Studies that encompass DDI screening in the wider context of medication therapy management (MTM).
Although such a methodological heterogeneity makes synthesis difficult, it offers complementary information about AI performance in various possible applications, ranging between rapid reference checking and full-scale medication review. The main strength of this evidence base is that the pharmacist-driven reference standards were used consistently, which confirms the fundamental comparator framework of this systematic review. The research makes use of three major groups of reference standards: Six reports were based on the use of standard clinical decision support systems (Lexicomp, Micromedex, Drugs.com) as reference standards.These databases are a reflection of institutio-nalized pharmacist knowledge, and include evidence-based advice that has been formulated through a systematic literature surveillance and formal review process by clinical pharmacists and physicians.
Five of these studies utilized direct evaluation by licensed pharmacists, with some being individual review of a single pharmacist and others being formal consensus evaluation by multiple clinical pharmacists. This method best reflects the clinical judgment which is the contemporary standard of care. In practice, clinical decision making is a collaborative process and two studies used multidisciplinary team evaluation, a combination of pharmacist, physician and other specialists' assessments of reference standards.The fact that such rigorous reference standards are applied in the majority of studies contributes greatly to the validity of the results and allows to meaningfully compare AI performance with the existing best practices.
The overall description of the studies included sheds light on a research area that is characterized by both potential and serious methodology issues. A number of common limitations affect the overall evidence base, such as the size of samples used to restrict statistical power and generalizability, inconsistent reporting of key parameters, such as AI model versions and imme-diate engineering approaches, and a bias towards detectivity rather than clinical practice and workflow support. This high level of methodological hetero-geneity, though indicative of an emerging and fast developing field, poses a critical inhibitor to making convergent conclusions. This fragmentation and the existing evidence gaps are what makes the rigorous, standardized synthesis of this systematic review nece-ssary and the following meta-analysis of more specific and generalizable estimates of AI performance relative to the standard, pharmacist-led care.
Mixed methods appraisal tool
Among the selected studies, the quality of methodology was critically appraised using Mixed Methods Appraisal Tool (MMAT) 2018. Given the diverse nature of the evidence base, the selection of the MMAT was appropriate, as it measures the methodo-logical rigour of various forms of study (qualitative, quantitative (RCT, non-RCT, descriptive) and mixed methods), all of which were represented.The review was done by two reviewers who did it independently. Both studies were compared to two screening question and then five study-specific criteria were used based on the design. The answers were taken as Yes, No or Can not tell. Any inconsistencies among reviewers were to be addressed by discussion in order to come up with a consensus.
The methodological quality of the included studies was assessed using the Mixed Methods Appraisal Tool 2018. All 14 studies met the two initial MMAT screening criteria, as they had clear research questions and collected data that were appropriate for addressing those questions. Most of the included studies were quantitative descriptive in design, while a smaller number included quantitative non-randomized, qualitative, or mixed-methods components. Overall, the methodological quality of the evidence was moderate. Common strengths across the included studies included relevant sampling strategies, appro-priate measurement of outcomes, and the use of pharmacist review, pharmacist consensus, pharmacist-validated databases, or multidisciplinary expert asses-sment as reference standards. These elements strength-hened the relevance of the evidence for comparing AI-generated outputs with pharmacist-led or pharmacist-validated standards.
Several methodological limitations were also identified. These included incomplete reporting of sample representativeness, unclear assessment of non-response bias, limited control of confounding in some studies, and insufficient reporting of important AI-related methodological details such as model version, prompt structure, evaluation protocol, and reproduci-bility procedures. These issues limited comparability between studies and reduced the certainty of the overall conclusions.
Taken together, the MMAT appraisal supports a cautious interpretation of the findings. Although the included studies provide useful evidence regarding the performance of AI systems in DDI screening and related clinical pharmacy tasks, methodological hetero-geneity and reporting gaps indicate the need for more standardized future research.
DISCUSSION
This systematic review focused on the performance of the AI-generated drug-drug interaction (DDI) alerts with pharmacists. The 14 studies synthesis demons-trates a field characterized by a high rate of innovation, as well as the high level of limitations and persistent ones. The major theme that appears is that of unfulfilled potential: although AI proves to be exceptionally good at information retrieval, its existing implementation to the high-stakes DDI-screening process is undermined by the crucial lack of reliability, clinical sensitivity, and safety. We can conclude that AI is, as of today, incapable of substituting the skills of a pharmacist, yet, through a cautious use of this techno-logy, it can become a useful tool.
One of the main problems of the interpretation of the literature is the seeming contradiction between the studies. This review solves this by defining the situations in which AI is most effective and ineffective, which is essential to determine its role in pharmacy.
Investigations by Van Nuland47 and Albogami34, has a positive perspective and demonstrates that AI may be safer and more proactive in providing accurate information than pharmacists would be on questions of factual knowledge. This is the main strength of AI as a strong information retrieval and education tool. The fact that it can quickly create information based on its extensive training corpus makes it very useful in answering specific pharmaco-logical questions or providing patient-friendly explana-tions, which may give pharmacists additional time to perform more complex tasks.
Yet, this strength has no reliable transfer to the dynamic and high stakes task of detecting clinical DDI. A larger amount of data studies by Bischof et al.41, Salama45, and Kim et al.36, shows deep flaws. When Bischof discovered that ChatGPT failed to identify the important QTc-prolonging interactions and Salama found that ChatGPT only detected DDI screening with 30 percent accuracy, this is a pattern of failure in clinical reasoning in practice. This is further developed in the study by Thapa et al.35, which illustrates an essential lack of connection: AI systems are often able to identify an interaction, but struggle to accurately measure its severity (37.3% accuracy) or to predict when it will occur (65.2% accuracy) – the exact information needed to make clinical decisions.
This dichotomy gives rise to two groups of AIs: an AIs that works well as a knowledge store and another one that fails as a clinical decision-maker. The favourable results are mostly relevant to the former, i.e. pattern recognition and recall of information based on its training data. The latter negative results reveal the weaknesses of the latter, which needs to be judged in a particular setting, stratify risk, and apply it to specific patient cases. This contradiction is therefore solved by acknowledging the fact that performance is very task specific. It is possible that AI is prepared to be used as a fast-access source or educational tool, but it is not prepared to make independent clinical decisions in the field of DDI management. In addition to simple accuracy measures, this review determines certain, interconnected failure modes that restrict the clinical utility and safety of existing AI systems to a serious degree.
The most serious flaw of any clinical tool is the absence of a life-threatening event. The inability of the models to reliably detect QTc-prolonging DDIs41 is a fatal blind spot. This is augmented by the fact that the use of LLMs has been documented to engage in hallucinating or confabulating information. A model may not just fail to capture an actual interaction, but may even create a non-existent one, or a management strategy that may sound plausible but which is totally incorrect. This puts the clinicians in a situation of a double jeopardy that they will not trust the occurrence or absence of an AI-generated alert.
AI models tend to generate long, confident-sounding statements that give the impression of knowledge. Nonetheless, as a study by Li et al.44, it may cover up important omissions and a basic lack of contextual sensitivity. As opposed to a pharmacist who considers the renal functionality, hepatic condition, age, genetic makeup and comorbidities of a patient, AI gives generalized, one-fit-all responses. As an example, the interaction between a renally excreted drug can be moderate in the case of a healthy adult and severe in the case of an elderly patient with chronic kidney disease-a difference that AI does not reliably distinguish. This is not personalized making its outputs clinically insignificant.
Total 90 percent inconsistency rate cited by Bischof et al.41, is the opposite of the medical practice. A pharmacist should have the capacity to believe that the same clinical question is going to have the same evidence-based response at all times. The unreliability of LLMs is devastating since the prompt can produce random results due to its probabilistic characteristics. This is compounded by the black box problem; in many cases, it is impossible to find out why an AI provided a particular response, and it is hard to test its reasoning, as well as learn its lessons, which further weakens clinical trust. This review should be understood considering the significant methodological weaknesses and hetero-geneity of the original studies. Although such variability is a sign of an emerging field, it makes it difficult to draw homogenous conclusions. Due to its fast iterative nature (e.g. GPT-3.5 to GPT-4o), a study published in 2023 can be assessing a far less able system in the year 2025. Numerous studies did not indicate the specific version that was tested and this seriously affected reproducibility. The performance of AI is extremely sensitive to the phrasing of a question. The results of a study conducted with complex, clinically based prompts will not be the same as those obtained with simple queries. This was a variable that was hardly controlled or reported in details. This indicates a potential methodological bias such as unblinded assessor or less demanding case scenarios that can blow up performance measures. This hetero-geneity not only prevented the realization of formal meta-analysis, but it also highlights the necessity to implement standardized evaluation frame-works (like the CONSORT-AI extension) in future studies. It also implies that the efficacy of any particular AI tool should be tested on the local clinical setting before it is allowed to be used.
Considering the shortcomings of AI, this review is a strong support of the necessity of the clinical pharmacist. The pharmacist-standard is not a database-search, it is a complex, multi-dimensional cognitive task. It involves examining the quality of evidence of a possible DDI. The pharmacist tailors the risk, depending on the health profile of the patient, including age and kidney functionality and other conditions. The pharmacist is then faced with a clinical judgment, balancing the possible harm of an interaction with the vital good that the medication does to the patient. Development of action management plans.
Li used direct pharmacist evaluation as the reference standard and all found the performance of AI to be wanting44. This highlights the fact that the gold standard is still the use of professional human judgment to validate and pharmacist edited databases such as Lexicomp and Micromedex. The interplay between the clinical reasoning of the pharmacist and these sources of authority is a strong, valid, and patient-centred care that the existing AI will never be able to replace47. The pharmacist role is therefore becoming more of a clinical integrator and decision-maker rather than an information verifier who is also able to take advantage of technology and exercise an irreplaceable human judgment.
Future research implications
In our findings, we provide the following evidence-based recommendations to manoeuvre through the given landscape and lead on the future development.
For Clinical Drug Drug Interactions (DDIs), we strongly discourage using large language models (LLMs) like ChatGPT or Google Gemini, where they are publicly and readily available.The risk of not identifying interactions or giving false advice is too high to continue using them. The dangers of the dangerous omissions, hallucinations, and inconsis-tencies are too high to be approved of patient care. Pharmacist-led review should be the standard practice and should not be set aside because of the availability of validated clinical decision support systems (CDSS) in EHRs. In case of the AI application, the role of the latter must be entirely supportive. Potential appli-cations of low-risk could be drafting of patient education material, and all results could be strictly checked and placed in context by a qualified pharmacist.
For future Research, development and Policy, create and test pharmacy-specific AI. Shift to specialized AI applications that work with trusted data on drugs and particular pharmacy work, and not general-purpose chatbots. One of the future directions is to combine LLMs with old-fashioned, rule-oriented CDSS. The rule-based system would serve as a safety net by making sure that critical DDIs are not overlooked, whereas the LLM would be able to help with complex reasoning, literature summarization, and commu-nication with the patients. The field needs to shift toward a standardized set of reporting policies including what AI model was applied, how it was activated, and in which cases it was not able to do so, so that comparisons can be made with other studies. This will enable making of meaningful comparisons and cumulative knowledge building. The research should transition beyond accuracy alone and investi-gate the possibilities of safely and smoothly intro-ducing AI tools into clinical workflows to reduce cognitive load and improve the efficiency. Finally, there needs to be research conducted to quantify the effects of the AI-supported pharmacy on the bottom line on patient outcomes and adverse drug events as well as hospital readmission rates.
Limitations of the study
There are a number of limitations of this systematic review that should be taken into account when interpreting the results. First, there was significant methodological variation in the studies included, both in terms of the AI models assessed, as well as the study design, the reference standards, the outcome measures, and reporting methods. Such methodologic differences made it difficult to make direct comparisons between studies and prevented the use of quantitative meta-analysis. Second, the majority of these studies used simulated clinical scenarios, drug-pair assessments or structured questionnaires instead of clinical imple-mentation, which may reduce the generalizability of the results. Third, some studies failed to provide explicit information on the versions of AI models employed, the strategies applied, and/or the evaluation protocols, limiting the replicability and comparability of the findings. Fourth, only English-language public-ations from 2022 forward were included, which could have led to language and publication bias. Lastly, because artificial intelligence is a field that is constantly evolving, the capabilities of existing models could change from the ones outlined in the studies included in this review and the results may not be seen as representative of the most current advances in AI.
CONCLUSIONS
Based on the synthesis of the evidence in general, the current state of functionality of the artificial intelligence as an information retrieval and learning tool is not adequate and safe to conduct autonomous clinical decision-making in screening of drug-drug interaction due to the severe gap in its reliability, clinical sensitivity, and contextual reasoning. The findings, including some adjustments like the method-logical heterogeneity, absence of reporting on AI versions, and high proportion of simulated tests compared to real-life tests, are clear indicators of the need to have the clinical pharmacist as the gold standard. Integration The future of integration hinges on the development of hybrid, pharmacy-specific AI tools, which run under the watch of pharmacists and the focus of research, has shifted to standardized assessment, workflow integration, and ultimately, the impact on hard patient outcomes.
