Public Release: 

Attitudes, practices surrounding end of life care in ICUs vary among Asian physicians

The JAMA Network Journals

A majority of physicians surveyed throughout Asia reported almost always or often withholding life-sustaining treatment in end-of-life care for patients in hospital intensive care units (ICUs) when there is little chance of meaningful recovery, although attitudes and practice of end-of-life care varied widely across countries and regions on the continent, according to a report published online by JAMA Internal Medicine.

Asia accounts for at least half of all patients with critical illness, mechanical ventilation and ICU deaths internationally but data on end-of-life care in ICUs in countries in Asia are sparse, according to background information in the study.

Jason Phua, F.R.C.P., of the National University Hospital, Singapore, and coauthors used survey data to describe physicians' attitudes toward withholding and withdrawal of life-sustaining treatments in end-of-life care and evaluate the factors tied to those attitudes. The survey was conducted among 1,465 physicians (physician response rate of 59.6 percent) who manage patients in 466 ICUs (ICU response rate of 59.4 percent) in 16 Asian countries and regions, including Bangladesh, China, Hong Kong, Iran and Thailand.

The majority of respondents (70.2 percent) reported they almost always or often withhold life-sustaining treatments for patients with no real chance of recovering a meaningful life, 20.7 percent almost always or often withdraw life-sustaining treatments, and 2.5 percent almost always or often deliberately give large doses of drugs, such as barbiturates or morphine, until the patient dies, according to survey results.

Survey results also indicate that 74.5 percent of respondents believe that withholding and withdrawing treatments were ethically different, a view supported by the majority of respondents in all countries and regions except Hong Kong and Singapore.

Of all the respondents, 84.1 percent and 77.9 percent, respectively, reported that patients' wishes and requests from family or surrogates were important factors when considering limiting life-sustaining treatment. However, only 43.9 percent of respondents were comfortable discussing limitation of care with families or surrogates and 35.6 percent of respondents said patients, families or surrogates almost always or often requested inappropriate life-sustaining treatments.

"Multiple factors related to country or region, including economic, cultural, religious and legal differences, as well as personal attitudes, were associated with these variations. Initiatives to improve end-of-life care in Asia must begin with a thorough understanding of these factors," the study concludes.

Commentary: How Asia Differs from the West

In a related commentary, Mervyn Koh, M.B.B.S., M.R.C.P., F.A.M.S., and Poi Choo Hwee, M.B.B.S., M.R.C.P., of Tan Tock Seng Hospital, Singapore, write: "Overall, Phua et al have successfully reflected the varying attitudes of Asian ICU physicians toward withdrawal and withholding of life-sustaining treatments. Moving forward, more research can be done to study ICU physicians' attitudes toward palliative care collaborations in Asia. Qualitative studies examining patients' and families' views on prolonged mechanical ventilation, withholding and withdrawal would also shed light on the complex influences affecting decision making and effective provision of end-of-life care for patients in the ICU. Subspecialty ICUs may also have differing practices that may be worthwhile to explore at a deeper qualitative level as well."
