Development of the mobile application Guide to medication reconciliation in the critically ill patient.

Objective: Medication reconciliation is an essential process in the care of critically ill patients, ensuring that patients' chronic medication is adapted to the patient's clinical situation and administered safely during hospitalisation. Given the profile of the patient admitted to a critical care unit (ICU), this becomes even more relevant. Reconciliation minimises possible medication errors and adverse effects, improving safety in the critically ill patient.

Methods: The project, carried out between 2021 and 2024, was led by the FarMIC (Pharmacists in Intensive Care Medicine and Critical Care) and RedFaster (Pharmaceutical Care in Emergencies) groups of the Spanish Society of Hospital Pharmacy (SEFH), and included: selection of the drugs, review of the available literature and previous conciliation guidelines in similar areas of application, preparation of the drug information with the recommendations issued by the working group, the review of the same and the development of the mobile application.

Results: In October 2024, the app 'Conciliation Guide for Critically Ill Patients®' was published, available free of charge for iOS and Android. It provides a drug index with detailed information on medication reintroduction schedules, routes of administration, monitoring, and drug-specific considerations. In addition, the tool includes information on withdrawal syndromes, drug-drug interactions with the usual ICU drugs and hazardous drugs information according to the NIOSH list.

Conclusions: This app facilitates pharmacotherapeutic reconciliation process in the ICU, supporting healthcare professionals in making personalised decisions. Its use can optimise patient safety, reduce adverse events and improve critical patient care. Finally, this tool reinforces the role of the clinical pharmacist in the ICU, who must lead this process in all care transitions and adapt it to the clinical situation of the patient.
