A Randomized Trial of an Interdisciplinary Communication Intervention to Improve Patient and Family Outcomes in the Intensive Care Unit

Three decades of research on end-of-life care in the United States indicate that people who are dying often spend their final days receiving care they would not choose. The intensive care unit (ICU) is an important focus for efforts to improve end-of-life care both because death is common in this setting - approximately 20% of Americans die in or shortly after a stay in the ICU - and also because care is highly technologic and, thus, expensive. As a result of our prior work we have developed a wealth of knowledge about how to improve communication and decision-making concerning end-of-life care in the ICU. One of the important insights from this knowledge was the need for and development of a facilitator-assisted interdisciplinary communication intervention. This intervention, designed to improve communication and decision-making about end-of-life care in the ICU, offers significant potential benefits for improving patient- and family-centered care for five reasons: 1) communication is an integral component of clinician skill that affects all other aspects of end-of-life care; 2) physicians and nurses in practice do not demonstrate adequate skills for communicating about end-of-life care, especially in the ICU or acute care setting; 3) interventions that have focused on improving communication within the ICU team and between the team and the family have been shown to reduce the "prolongation of dying" common in the ICU, but it remains unclear how to generalize these successes to other hospitals; 4) a recent randomized trial in France used an intervention based on our prior research and showed dramatic reductions in symptoms of anxiety, depression, and post-traumatic stress disorder (PTSD) among family members after the patient's death, but it is unclear how to translate these findings to hospitals in the U.S.; and 5) sustainable, generalizable, and widely available interventions that improve communication about end-of-life care are not available.

The long-term objectives are: 1) to demonstrate the efficacy of a generalizable facilitator-assisted interdisciplinary communication intervention in the ICU to improve family and patient outcomes; and 2) to demonstrate the feasibility of making this intervention a routine part of clinical practice in the ICU setting.

The study will advance Nursing science by addressing an important area of emphasis within Nursing science and a key component of the National Institute of Nursing Research's strategic plan. One fifth of deaths in America occur in intensive care units and nurses provide a key component of the care in this setting. With the aging population and coincident advances in medical technology, more patients are likely to die after an unsuccessful trial of intensive care. Prior research suggests that interventions to improve communication about end-of-life care in the ICU may reduce the prolongation of dying that is common in the ICU setting while at the same time improving the quality of care for patients and family members. Unfortunately, this prior research does not provide a clear generalizable intervention that can be easily implemented in academic and community hospitals. The proposed randomized trial will test a feasible and generalizable intervention to improve communication about end-of-life care and improve patient and family outcomes.

The consent forms used for this study address the purpose, procedures, risks, alternatives, benefits, and other information -- including emphasis on the voluntary nature of this research and assurances of confidentiality.

The conceptual model for the intervention addresses three components of self-efficacy theory: 1) knowledge, based on this team's prior research identifying components of communication during ICU family conferences that are associated with improved patient and family outcomes; 2) attitudes, informed by attachment theory as applied to clinician-patient relationships and communication; and 3) communication behaviors informed by principles of mediation based on identifying and resolving conflict in the healthcare setting.
