Analysis of emergency department management of suspected bacterial meningitis

Ann Emerg Med. 1989 Aug;18(8):856-62. doi: 10.1016/s0196-0644(89)80213-6.


Previous studies of emergency department management of bacterial meningitis have indicated that there are often long delays before initiation of antibiotics. The purpose of our study was to determine whether these delays were related to specific aspects of patient management. From 1981 through 1988, we retrospectively reviewed the medical records of 122 patients primarily evaluated in the ED and admitted for suspected bacterial meningitis at a university (55) and a community (67) hospital. The median time (interquartile range) from ED registration until initiation of antibiotics (time to antibiotics) was 3.0 hours (1.6 and 4.3 hours, respectively) (total range, 0.5 to 18 hours). The time to antibiotics was not significantly related to the time of ED registration. Ninety percent of the total time to antibiotics occurred after the initial physician encounter. Time to antibiotics was significantly (P less than .00005) longer for patients in whom computed tomography scan and/or laboratory analysis of cerebrospinal fluid preceded initiation of antibiotics compared with patients in whom antibiotic administration was not contingent on the results of these procedures (4.3 [3.2 and 6.0] versus 1.9 [1.2 and 3.4] hours, respectively). Also, time to antibiotics was significantly (P less than .00005) longer for patients in whom antibiotics were initiated on the ward as compared with in the ED (4.5 [3.5 and 6.8] versus 2.2 [1.4 and 3.5] hours, respectively). We conclude that long delays exist in the ED before initiation of antibiotics for cases of suspected bacterial meningitis, and that in general these delays appear to be physician generated and to a great extent potentially avoidable.
