{ "abstract": "Background\n\nAI is a broad field encompassing various techniques, which include algorithms that learn from data to perform automated tasks without explicit human programming. Public health aims to protect and improve the health of communities and populations at the local, regional, national, and global levels, but it typically has limited resources. While AI may lead to improved efficiency or effectiveness of public health interventions, the adoption of AI interventions should be informed by evidence of effective use in practice.Objective\n\nThis review aims to summarize how AI-assisted interventions are currently used by public health professionals.Methods\n\nWe conducted a scoping review to identify the current uses of AI in public health. We searched MEDLINE (Ovid), Embase (Ovid), Web of Science (Core Collection), and Scopus for relevant reports published between January 1, 2020, and July 24, 2025. Two reviewers independently screened reports. Eligible reports were primary studies (experimental or observational), commentaries, and editorials that discussed how AI tools have been used in practice in public health contexts relevant to high-income countries, excluding outbreaks. Data were extracted by one reviewer and checked by a second.Results\n\nWe screened 5400 records and 155 full texts, including 8 reports. These reports discussed a variety of uses of AI tools across public health domains: 3 reports used chatbots in different settings, 1 report used machine learning to forecast health service demand, 2 reports used AI for symptom checking, and 2 reports used AI for evidence synthesis. While assessing the effectiveness of AI tools for public health was beyond the scope of this review, and most reports did not robustly evaluate effectiveness, the evidence for the effectiveness of AI tools was nonetheless mixed. One report described a chatbot that users found helpful, while another found a specific chatbot to be ineffective, highlighting its potential to undermine trust in the organization that developed it. Another report highlighted both benefits and drawbacks of a large language model used to communicate with socially isolated individuals. The main finding of this review was that even with a comprehensive search across multiple databases, there were few reports of how AI tools are being used in practice in public health contexts.Conclusions\n\nThe lack of evidence from public health practice, excluding outbreaks, makes it difficult to know which uses of AI, if any, would be useful to incorporate into practice in high-income countries. In the absence of evidence, new interventions, including those using AI, should be evaluated to ensure they are effective (and cost-effective). These evaluations should be widely and accessibly disseminated to create an evidence base that other public health teams could use to inform their own decisions around AI tools.", "abstract_shown": true, "affiliations": [ "University of Exeter Medical School, University of Exeter, St Luke's Campus, Heavitree Road, Exeter, England, EX1 2LU, United Kingdom, 44 1392 661000.", "Public Health Wales, Cardiff, Wales, United Kingdom.", "Cardiff University, Cardiff, Wales, United Kingdom.", "University of Birmingham, Birmingham, England, United Kingdom." ], "article_type": "scoping review", "arxiv": null, "author_total": 14, "authors": [ { "affs": [ 0 ], "name": "Sean Harrison", "orcid": "0000-0002-7966-0700" }, { "affs": [ 0 ], "name": "Claire Tatton", "orcid": "0000-0002-2870-3774" }, { "affs": [ 0 ], "name": "G J Melendez-Torres", "orcid": "0000-0002-9823-4790" }, { "affs": [ 0 ], "name": "Joelle Kirby", "orcid": "0009-0002-3273-8790" }, { "affs": [ 0 ], "name": "Sophie Robinson", "orcid": "0000-0003-0463-875X" }, { "affs": [ 0 ], "name": "Daniel Mutanda", "orcid": "0009-0008-7288-2141" }, { "affs": [ 1 ], "name": "Alisha Davies", "orcid": "0000-0002-8066-7264" }, { "affs": [ 0 ], "name": "Jessica M Armitage", "orcid": "0000-0002-0929-9956" }, { "affs": [ 2 ], "name": "Rabeea'h Waseem Aslam", "orcid": "0000-0002-0916-9641" }, { "affs": [ 0 ], "name": "Tom Arthur", "orcid": "0000-0002-1018-3627" }, { "affs": [ 3 ], "name": "Joht Singh Chandan", "orcid": "0000-0002-9561-5141" }, { "affs": [ 0 ], "name": "Ruth Garside", "orcid": "0000-0003-1649-4773" }, { "affs": [ 0 ], "name": "Jo Thompson Coon", "orcid": "0000-0002-5161-0234" }, { "affs": [ 2 ], "name": "Rhiannon Evans", "orcid": "0000-0002-0239-6331" } ], "bibtex": "https://research.draconitic.com/paper/9zadkav00b6z3.bib", "cited_by": 0, "doi": "10.2196/108250", "fulltext_url": "https://europepmc.org/articles/PMC13718742", "id": "9zadkav00b6z3", "issns": [ "1439-4456", "1438-8871" ], "landing_url": "https://europepmc.org/article/MED/42956087", "language": "eng", "licence": "CC-BY", "licence_label": "CC BY", "licence_source": "article", "licence_url": "https://creativecommons.org/licenses/by/4.0/", "metadata_licence": null, "native_subjects": [ [ "heading", "AI Applications in Public Health" ], [ "heading", "Artificial Intelligence" ], [ "heading", "Digital Contact Tracing, Digital Proximity Tracing, Precision Public Health" ], [ "heading", "Digital Health Reviews" ], [ "heading", "Health Informatics Education and Training" ], [ "heading", "Innovative Methods in Public Health and Surveillance" ], [ "heading", "Review" ], [ "openalex", "2718|Artificial Intelligence in Healthcare and Education" ] ], "openalex": "W7213946455", "pdf_url": "https://europepmc.org/articles/PMC13718742?pdf=render", "pmcid": "PMC13718742", "pmid": "42956087", "published": "2026-10-29", "publisher": "JMIR Publications Inc.", "ris": "https://research.draconitic.com/paper/9zadkav00b6z3.ris", "sources": [ { "first_seen": "2026-11-01T00:20:36Z", "native_id": "MED:42956087", "source": "europepmc", "url": "https://europepmc.org/article/MED/42956087" }, { "first_seen": "2026-11-02T12:22:42Z", "native_id": "PMC13718742", "source": "pmc", "url": "https://doi.org/10.2196/108250" } ], "subjects": [ { "field": "medicine", "origin": "openalex:2718|Artificial Intelligence in Healthcare and Education", "subfield": "epidemiology-public-health" } ], "title": "The Current Roles of AI in Public Health Practice: Scoping Review.", "title_text": "The Current Roles of AI in Public Health Practice: Scoping Review.", "type": "peer-reviewed", "updated_at": "2026-11-02T12:22:42Z", "url": "https://research.draconitic.com/paper/9zadkav00b6z3", "venue": "Journal of medical Internet research", "versions": [] }
