Tackling client absenteeism in primary and secondary care settings is crucial to ensure the continuity of care for individuals, familiesand communities, as well as preventing waste of resources within healthcare systems. This article is an integrative review to identify advancements in health technologies that addressclient absenteeism in primary and secondary care. The databases Medical Literature and Retrieval System Online (MEDLINE/PubMed®), Scientific Electronic Library Onlineand Virtual Health Librarywere consulted. The inclusion criteria were as follows: full papers, published between 2013 and 2023, in English, Portugueseor Spanish. The descriptors used were the following: patients, mobile applications, health services management, absenteeismand primary care, and secondary care. Eleven articles published from 2014 to 2021 were included. Most articles were identified in the MEDLINE/PUBMED database, employed a randomized controlled trial methodology (36.36%), and were published between 2019 and 2021 (90.0%) in English (63.7%). The applications had managerial, assistiveand/or educational purposes. In addition to absenteeism control, these applications strived to promote client engagement with health services, increase health literacyand tackle structural barriers to care, such as language barriers. Efforts are needed to ensure that providers receive training to educate clients on the applications. Moreover, community-based participatory studies to ensure the feasibility of applications are warranted.
