About

Communication is one of the greatest health needs for high quality end-of-life (EOL) care in the intensive care unit (ICU), especially when patients are too ill to speak for themselves and rely on surrogates to make EOL decisions. Yet, there is no effective nursing intervention designed to improve communication between surrogates and clinicians. In order to enhance understanding of the surrogates' needs in the transition to EOL, this study will propose a new theory-grounded communication intervention, Nurse-Led Communication Strategy (NLCS) and will evaluate its feasibility, acceptability, and preliminary effects.

Full description

Background: In 2014, 14.7% of Americans died using intensive care unit (ICU) services. It is a clinical imperative to provide high quality EOL care. Strong communication with surrogates is vital for high quality EOL care due to the fact that seriously ill patients often cannot talk, and they rely on surrogates (often family members) to make EOL decisions. There have been many studies conducted in the past, trying to improve EOL communication. Yet, evidence shows that communication remains poor in the ICU. To date, there is lack of evidence for a particular nursing strategy that effectively improves communication and the quality of EOL care in the ICU. The goal of this proposed study is to develop a new nurse-led communication strategy (NLCS). Specific Aim: To assess the NLCS's feasibility, acceptability, and preliminary effects among surrogates of patients who are unable to communicate in the ICU. Theory: NLCS is grounded in the state-of-the art framework "COMFORT" which has guided a validated and effective communication training for nurses in the care of patients with life-threatening illness and their families. NLCS applies 'COMFORT' into a usable nursing communication strategy that research nurses use the framework to engage one communication session per day with surrogates during the ICU stay. Methods: A single-center pilot two-groups comparison study. The study design involves the recruitment of surrogates in the ICU to evaluate the feasibility, acceptability, and preliminary effects of the NLCS. Analysis: To assess feasibility, we will use descriptive statistics and a COSORT (Consolidated Standards of Reporting Trials) flow diagram to determine recruitment and attrition. For acceptability, we will use an unpaired (independent) t test to compare the scores of the Client Satisfaction Questionnaire (CSQ-8)and between intervention and control groups. To evaluate preliminary effects of the intervention, we will compare the pre- and post-test scores of the Quality of Communication (QOC) questionnaire, Hospital Anxiety and Depression Scale (HADS), and Decisional Conflict Scale (DCS) between intervention and control groups. It determines whether the NLCS is perceived as appropriate, acceptable, and potentially effective. The by-product analysis uses a linear regression to determine which factors are associated with the scores of the . This proposal provides an opportunity for the first time to develop a theory-grounded nursing communication strategy that is feasible, acceptable, and poses low cognitive load for surrogates in the ICU, and it enhances the understanding of surrogates' needs in the transition to EOL and thereby potentially improves the quality of EOL care. This research training will take place at the University at Buffalo School of Nursing, an exceptional research-intensive university, under the mentorship of Dr. Chang and Dr. Lorenz (methodology), Dr. Sullivan (EOL studies), and Dr. Wittenberg (communication theory). The training plan will provide the investigator with research skills and the preliminary data.

---

41 participants in 3 patient groups

Assess the NLCS' feasibility

Experimental group

Description:

Hypothesis: No significant differences will be observed in recruitment and attrition between NLCS intervention and control groups. Approach: Determine rates of enrollment and drop-outs between groups.

Treatment:

Behavioral: nurse-led communication strategy

Assess the NLCS' acceptability

Experimental group

Description:

Hypothesis: More surrogates agree that the NLCS is suitable, appropriate, effective and willing to adhere versus treatment as usual (TAU) communication. Approach: Assess outcome using the validated instrument, Client Satisfaction Questionnaire (CSQ-8).

Treatment:

Behavioral: nurse-led communication strategy

Assess the NLCS' preliminary effects

Experimental group

Description:

Hypothesis: NLCS improves communication and decreases surrogates' psychological distress (e.g., anxiety and depression) Approach: Compare pre- and post-intervention scores of the Quality of Communication (QOC) questionnaire, Hospital Anxiety and Depression Scale (HADS), and Decisional Conflict Scale (DCS) between intervention and control groups.

Treatment:

Behavioral: nurse-led communication strategy
