Background Little is known about the attitudes and practices of intensivists working in Lebanon regarding withholding and withdrawing life-sustaining treatments. The objectives of the study were to assess the points of view and practices of intensivists in Lebanon along with the opinions of medical, legal and religious leaders regarding withholding withdrawal of life-sustaining treatments in Lebanese intensive care units. Methods A web-based survey was conducted among intensivists working in Lebanese adult ICUs. Interviews were also done with Lebanese medical, legal and (...) religious leaders. Results Of the 229 survey recipients, 83 intensivists completed it, i.e. a response rate of. Most respondents were between 30 and 49 years old, Catholic Christians, anesthesiologists, working in Beirut. Ninety-two percent of them were familiar with the withholding and withdrawal concepts and 80% applied them. Poor prognosis of the acute and chronic disease and futile therapy were the main reasons to consider withholding and withdrawal of treatments. Ninety-five percent of intensivists agreed with the “Principle of Double Effect”. The main withheld therapies were vasopressors, respiratory assistance and CPR. Most of the respondents reported the decision was often to always multidisciplinary, involving the family, and the patient, or his advance directives or his surrogate and the nurses. The interviewees agreed there was a law governing withholding and withdrawal decisions/practices in Lebanon. Christians and Muslim Sunni leaders declared accepting those practices. Conclusion Withholding and withdrawal of LSTs in the ICU are known concepts among intensivists working in Lebanon and are being practiced. Our results could be used to inform and optimize therapeutic limitation in ICUs in the country. (shrink)
