Patient Agitation in the Intensive Care Unit: A Concept Analysis

Abstract

Aim

Exploring the concept of patient agitation in the intensive care unit.

Background

Patient agitation in the intensive care unit is of widespread concern and linked to negative outcomes for patients, staff, and family members. There is currently no consensus on what constitutes agitation in the intensive care context, hindering effective and tailored prevention and management.

Design

Concept Analysis.

Method

Walker and Avant's eight-step concept analysis approach.

Data Sources

A comprehensive search was carried out in the databases MEDLINE, PsychINFO and CINAHL. A total of 32 papers published between 1992 and 2023 were included, reviewed, and analysed to explore definitions, attributes, antecedents and consequences of patient agitation.

Results

Patient agitation in the intensive care unit is characterised by excessive motor activity, emotional tension, cognitive impairment, and disruption of care, often accompanied by aggression and changes in vital signs. Antecedents encompass critical illness, pharmacological agents and other drugs, physical and emotional discomfort, patient-specific characteristics and uncaring staff behaviours. Consequences of agitation range from treatment interruptions and poor patient outcomes to the psychological impact on patients, families, and staff.

Conclusion

Agitation in the intensive care unit is a complex issue which significantly impacts patient treatment and clinical outcomes. For healthcare professionals, patient agitation can contribute to high workloads and job dissatisfaction. Due to the complex nature of agitation, clinicians must consider multifaceted strategies and not rely on medication alone. Further research is needed to fully understand patient agitation in the ICU. Such understanding will support the development of improved strategies for preventing and managing the behaviours.

Implications

A clearer understanding of patient agitation supports the development of tailored interventions that improve patient care, guide ICU training, and inform future research.
