Nurses, as front-line care providers, strive to offer adequate care to their clients. They have acquired valuable experiences during the COVID-19 pandemic that enhance the nursing profession. This study aimed to explore nurses' caring experiences in the COVID-19 pandemic. This is a qualitative meta-aggregative systematic review. Electronic databases (Google Scholar, PubMed, Web of Science, CINHAL) in English were searched to find out the meaningful subjective data on the COVID-19 pandemic. The inclusion criteria were studies published in English related to nurses' caring experiences in the COVID-19 pandemic. Seventeen qualitative studies with several approaches were included. Three key themes were identified from the studies: Weaknesses and strengths of nursing at the beginning of the pandemic, Nursing beyond challenges related to the pandemic, and Family and career challenges. Nurses face different challenges in caring for patients with COVID-19 that benefit the health and nursing professions. Governments, policymakers, and managers have to support nurses during and after the pandemic. Without enough support, nurses are likely to experience significant psychological issues that can lead to burnout and frustration.
