Q: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Despite recent advancements in post-cardiac arrest resuscitation, the optimal measurement of postarrest outcome remains unclear. We hypothesized that Cerebral Performance Category score can predict the long-term outcome of postarrest survivors who received targeted temperature management during their postarrest hospital care.', 'Retrospective chart review.', 'Two academic medical centers from May 2005 to December 2012.', 'The medical records of 2,417 out-of-hospital and in-hospital patients post cardiac arrest were reviewed to identify 140 of 582 survivors who received targeted temperature management.', 'None.', 'The Cerebral Performance Category scores at hospital discharge were determined by three independent abstractors. The 1-month, 6-month, and 12-month survival of these patients was determined by reviewing hospital records and querying the Social Security Death Index and by follow-up telephone calls. The association of unadjusted long-term survival and adjusted survival with Cerebral Performance Category was calculated. Of the 2,417 patients who were identified to have undergone cardiac arrest, 24.1% (582/2,417) were successfully resuscitated, of whom 24.1% (140/582) received postarrest targeted temperature management. Overall, 42.9% of patients (60/140) were discharged with Cerebral Performance Category 1, 27.1% (38/140) with Cerebral Performance Category 2, 18.6% (26/140) with Cerebral Performance Category 3, and 11.4% (16/140) with Cerebral Performance Category 4. Cerebral Performance Category 1 survivors had the highest long-term survival followed by Cerebral Performance Categories 2 and 3, with Cerebral Performance Category 4 having the lowest long-term survival (p < 0.001, log-rank test). We found that Cerebral Performance Category 3 (hazard ratio = 3.62, p < 0.05) and Cerebral Performance Category 4 (hazard ratio = 12.73, p < 0.001) remained associated with worse survival after adjusting for age, gender, race, shockable rhythm, time to targeted temperature management initiation, total duration of resuscitation, withdrawal of care, and location of arrest.
