End-of-life care preferences for people with advanced cancer and their families in intensive care units: a systematic review

BackgroundAdvanced cancer patients' end-of-life care preferences in oncology units, medical-surgical units, nursing homes and palliative care services have been established. However, less is known about end-of-life care preferences of patients with advanced cancer in intensive care units and their families.AimTo explore end-of-life care preferences of patients with advanced cancer and their families in intensive care units and if these align with essential elements for end-of-life care.DesignElectronic databases were searched up to February 2018. Reference lists of retrieved articles were screened for potential studies.ResultsA total of 112 full text articles were retrieved. Of these, 12 articles reporting outcomes from 10 studies were eligible for inclusion. The majority were retrospective chart reviews (n=7) and conducted in developed countries (n=9). Care preferences change over time with deteriorating physical condition. Ongoing patient-centred communication and shared decision-making are critical as is teamwork and involvement of a palliative care team. Marital status, gender and ethnicity appear to influence care preferences. Of those studies examining patient preferences and/or the receiving of their preferences, these could be aligned with approximately half of the Australian essential elements for end-of-life care.ConclusionsProviding end-of-life care for patients with advanced cancer in intensive care units is challenging. No studies have investigated prospectively the end-of-life care preferences of patients and their families in this acute setting. Further research is required to determine the elements of care preferences for patients with advanced cancer and their families in intensive care units in developing countries.
