Do psychological interventions reduce preoperative anxiety?

Abstract

The systematic review investigates whether, during preoperative assessments, nurse-delivered psychological interventions reduce anxiety levels preoperatively for patients undergoing elective surgery. Seventeen studies met the inclusion criteria for data extraction and in-depth critiquing. Of these, two were discarded due to lack of validity, while the remaining studies were organised thematically in a narrative synthesis, generating two principal results: patients' preoperative anxieties were lowered by nurse-delivered general preoperative psychological interventions; and patients valued individualised preoperative interventions delivered by nurses. However, the single oncology study in the review showed an elevation in preoperative anxiety, regardless of intervention, and highlights the need for more research in this under-reviewed area. In the meantime, the authors believe that service improvements should be implemented to ensure that, where possible, psychological preoperative interventions are individualised.
