Objective:

To identify factors that influence the quality of care provided in the Intensive Care Unit.

Methodology:

Literature review was carried out in the databases Web of Science, EBSCO, Scopus, PubMed and Virtual Health Library, in addition to Google Scholar search engine. Standardized descriptors were used in MeSH and DeCS, establishing the search strategies "nursing care AND icu AND quality NOT pediatrics" and "nursing AND icu AND quality of health care". The eligibility criteria used were: qualitative, quantitative and/or review studies related to the topic to be studied. A first screening was performed by title and abstract, eliminating references that did not meet the eligibility criteria, then duplicates were eliminated and a final screening was performed for fulltext selection with critical reading tools of the Critical Appraisal Skills Programme (CASPe).

Results:

Factors that directly and/or indirectly influence the quality of care provided in Intensive Care Units were identified, in which workload, moral fatigue and psychological wear and tear stand out.

Conclusions:

Workload, moral fatigue and psychological burnout directly and indirectly influence the delivery of care in intensive care units.
