Introduction

Early and balanced replacement of blood products appears to be the key factor in improving outcomes of major bleeding patients including acute trauma, cardiac, obstetric and transplant surgery patients. Definitive clinical guidance regarding the optimal ratio of blood products, including those containing fibrinogen, is still lacking. Therefore, we tested the hypothesis that increasing the fibrinogen content to erythrocyte suspension ratio improves the mortality and functional outcomes of patients undergoing surgeries with expected major bleeding.

Methods and analysis

The Approximate Dose-Equivalent of Fibrinogen-to-Erythrocyte Suspension (ADEFES) ratio is a multicentre, prospective, observational, cohort study of patients undergoing major surgical procedures with expected major perioperative bleeding (ie, requiring packed red blood cells (PRBC)>4U/24 hours). For 5U of cryoprecipitate and 1.5 U of fresh frozen plasma (FFP), the approximate dose-equivalent for fibrinogen is considered as 1 gram of fibrinogen. Association of the ADEFES ratio at 24 hours will be assessed on the primary objective, which will consist of the composite of 30-day all-cause mortality, 30-day bleeding-specific mortality and the ‘highly-dependent scores’ of Katz index of independence in activities of daily living.

Ethics and dissemination

The study protocol was approved by the Ethics Committee of Ankara Bilkent City Hospital (approval no. E2-23-4265, dated 07 June 2023; Chair: Prof. Dr. F.E. Canpolat) and by the institutional review boards of all participating centres. The study will be conducted in accordance with the principles of the Declaration of Helsinki and the Strengthening the Reporting of Observational Studies in Epidemiology guidelines, as well as in compliance with national regulations on data protection and Good Clinical Practice standards. Written informed consent will be obtained from all participants prior to inclusion in the study.

The results of this study will be disseminated through peer-reviewed scientific journals, presentations at national and international conferences, and communication with relevant stakeholders including clinical practitioners and healthcare institutions. If applicable, study outcomes will also be shared via institutional newsletters and digital platforms to reach a broader audience in the medical community.

Abstract

Aims and Objectives

This study aims to determine the relationship between perceptions of nursing presence and intensive care experiences in adult intensive care unit patients'.

Background

Intensive care units (ICUs) are settings where patients have many negative emotions and experiences, which affect both treatment and post-discharge outcomes. The holistic presence of nurses may help patients turn their negative emotions and experiences into positive ones.

Design

A descriptive-correlational design was used and reported according to the STROBE checklist.

Methods

The sample consisted of 182 participants. Data were collected using a personal information form, the Glasgow Coma Scale (GCS), the Intensive Care Experience Scale (ICES), and the Presence of Nursing Scale (PONS).

Results

A strong positive correlation existed between total ICES and PONS scores (r = 0.889, p < 0.001). There was a strong positive correlation between PONS total score and ICES subscales (awareness of surroundings (r = 0.751, p < 0.001), frightening experiences (r = 0.770, p < 0.001), recall of experience (r = 0.774, p < 0.001), and satisfaction with care (r = 0.746, p < 0.001)). Males (β = −0.139, p < 0.05), and patients who were university and higher education graduate (β = 0.137, p < 0.05) had higher positive ICU experiences. It was also found length of ICU stay was correlated with ICU experiences and nursing presence.

Conclusions

The more positively the patients perceive nurses, the better ICU experiences they have. Gender and education level were found determinants of adult ICU patients' experiences. ICU length of stay predicted what kind of experience patients have and how much they feel the presence of nurses.

Relevance to Clinical Practice

Nurses should make their presence felt completely and holistically by using their communication skills for patients have more positive intensive care experiences. Nurses should consider variables which affects patients' ICU experiences and nursing presence.
