Evidence-based recommendations concerning how to discuss dying, life expectancy, and likely future symptoms with patients with a limited life expectancy and their families are lacking. The aim of this systematic review was to review studies regarding prognostic/end-of-life communication with adult patients in the advanced stages of a life-limiting illness and their caregivers. Relevant studies meeting the inclusion criteria were identified by searching computerized databases up to November 2004. One hundred twenty-three studies met the criteria for the full review, and 46 articles reported on patient/caregiver preferences for content, style, and timing of information. The majority of the research was descriptive. Although there were individual differences, patients/caregivers in general had high levels of information need at all stages of the disease process regarding the illness itself, likely future symptoms and their management, and life expectancy and information about clinical treatment options. Patient and caregiver information needs showed a tendency to diverge as the illness progressed, with caregivers needing more and patients wanting less information. Patients and caregivers preferred a trusted health professional who showed empathy and honesty, encouraged questions, and clarified each individual's information needs and level of understanding. In general, most patients/caregivers wanted at least some discussion of these topics at the time of diagnosis of an advanced, progressive, life-limiting illness, or shortly after. However, they wanted to negotiate the content and extent of this information.
Many health professionals (HPs) express discomfort at having to broach the topic of prognosis, including limited life expectancy, and may withhold information or not disclose prognosis. A systematic review was conducted of 46 studies relating to truth-telling in discussing prognosis with patients with progressive, advanced life-limiting illnesses and their caregivers. Relevant studies meeting the inclusion criteria were identified by searching computerized databases (MEDLINE, EMBASE, CINAHL, PsychINFO and Cochrane Register of Controlled Trials) up to November 2004, with handsearching of studies, as well as inclusion of studies satisfying selection criteria reported in 2005 by the authors. The reference lists of identified studies were hand-searched for further relevant studies. Inclusion criteria were studies of any design evaluating communication of prognostic information that included adult patients with an advanced, life-limiting illness; their caregivers; and qualified HPs. Results showed that although the majority of HPs believed that patients and caregivers should be told the truth about the prognosis, in practice, many either avoid discussing the topic or withhold information. Reasons include perceived lack of training, stress, no time to attend to the patient's emotional needs, fear of a negative impact on the patient, uncertainty about prognostication, requests from family members to withhold information and a feeling of inadequacy or hopelessness regarding the unavailability of further curative treatment. Studies suggest that patients can discuss the topic without it having a negative impact on them. Differences and similarities in findings from different cultures are explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
