Our Sep editorial: Patient safety needs innovation Advances in the applications of ArtificialIntelligence and other technologies in health & medicine require rethinking of what PatientSafety means. WorldPatientSafetyDay2022 MachineLearning SaMD

on 17 September is ‘medication without harm’. The campaign is focused on ‘traditional’ drugs — chemical compounds — for which regulations and standards have been developed to ensure that they are safe before being given to patients.

In the specific case of AI, regulatory bodies have begun to take steps to guide preclinical development, so that the formal approval process and potential market entry — which require that interventions are proven to be effective as well as safe in patients — can be made more consistent. To demonstrate the potential relevance and safety of AI in the real world, translational AI and machine learning studies are recommended to follow the US Food and Drug Administration ’s guiding principles on.

How adverse events present and are assessed in patients requires rethinking in the context of ‘variable’ iterative interventions. Although AI algorithms approved by the FDA have so far been locked before entering the market, the application of models that continuously learn and develop once exposed to real-world populations has to be regulated differently to ‘static’ interventions.

There is also potential for SaMDs to exacerbate existing health inequalities and systemic biases in the real world, representing risks to patient safety on a large scale. For example, AI-based prediction models of chest X-rays are more likely toif they are members of underserved populations. Training and testing of SaMDs in diverse populations before release is crucial to prevent such outcomes, as well as avoiding the use of socially constructed categories, such as race, in SaMDs.

Advancing T cell–based cancer therapy with single-cell technologies - Nature MedicineTo accelerate the development of T cell–based immunotherapies that are effective for more patients with cancer, there is an urgent need to decipher the precise attributes of the ideal therapeutic T cell. In March 2021, the Parker Institute of Cancer Immunotherapy and 10x Genomics partnered to bring together a group of T cell immunotherapy researchers and single-cell-technology innovators for a day’s workshop. Participants evaluated the current cutting edge of knowledge, identified areas for focused technology development, and put forward a call to action to the field. Insights were provided on how to best leverage single-cell technologies and key areas for future development were proposed — with the goal of facilitating a better understanding of T cell research and translation of this research into effective cancer immunotherapies. The key points of discussion that emerged from this workshop are summarized here.
