The effectiveness of an emergency department nursing intervention on psychological symptoms and self-care capacities: A randomized controlled study protocol

Abstract

Background: We carried out a randomized trial of an emergency department (ED)-based nursing intervention to evaluate the impact of an ED nursing intervention on ED revisits, patient perceptions of continuity of care, illness perceptions, self-care capacities and psychological symptoms.

Method: We conducted a randomized controlled trial to compare the ED-based intervention with usual care. The protocol was reviewed and approved by the Research Ethics Board of the Huzhou Central Hospital & Affiliated Central Hospital Huzhou University (K901923-021), each participant signed a written consent before participating, and SPIRIT guidelines were followed throughout. To be eligible, patients ready for discharge from the ED had to be at risk for ED return based on 2 criteria: at least one ED visit during the year prior to the initial visit, and current treatment with at least 6 medications. Exclusion criteria included cognitive problems (e.g., dementia) that would preclude provision of informed consent either noted in the medical chart or identified based on the clinical judgment of the project nurse. To avoid multiple interveners for the same patient, we also excluded patients already receiving other regular follow-up (e.g., at a specialized clinic in the hospital or from external resources). The major outcomes were assessed with the Heart Continuity of Care Questionnaire, the Illness Perception Questionnaire-Revised, the Therapeutic Self-Care Tool, the Hospital Anxiety and Depression Scale, and the Self-Reported Medication-Taking Scale.

Results: Two hundred patients who met the inclusion criteria were included in our study, Table 1 showed the effects of nursing intervention on measures of clinical outcomes.

Discussion: The ED is a major entry point into the health care system of many countries. Unnecessary ED revisits may result in overcrowding, increased waiting time, and failure to provide appropriate emergency care. The ED-based interventions literature focuses primarily on service use and ways to reduce ED revisits, with very little focus on impacting secondary outcomes. Because of their potential link with health service utilization, secondary outcomes such as perceived continuity of care, illness perceptions, self-care capacities, psychological symptoms and medication adherence might influence ED revisits. Future research was needed to better understand the complex relationship between ED utilization and a variety of intermediary factors in order to develop interventions that will optimize ED utilization.
