Variable parameters were collected from the patients' medical records and radiological data. A comparison was made between patients with favorable [Glasgow Outcome Scale (GOS) ${\geq}4$] and unfavorable (GOS &lt;4) outcomes at discharge. Additionally, we investigated the factors influencing the duration of antibiotic administration. Results : The study included 41 male and 10 female patients with a mean age of 53 years. At admission, 42 patients (82%) showed either clear or mildly disturbed consciousness (GCS ${\geq}13$) and 24 patients (47%) had predisposing factors. The offending microorganisms were identified in 25 patients (49%), and Streptococcus species were the most commonly isolated bacteria (27%). The mean duration of antibiotic administration was 42 days. At discharge, 41 patients had a favorable outcome and 10 had an unfavorable outcome including 8 deaths. The decreased level of consciousness (GCS &lt;13) on admission was likely associated with an unfavorable outcome (p=0.052), and initial hyperglycemia (${\geq}140mg/dL$) was an independent risk factor for prolonged antibiotic therapy (p=0.032). Conclusion : We found that the level of consciousness at admission was associated with treatment outcomes in patients with brain abscesses. Furthermore, initial hyperglycemia was closely related to the long-term use of antibiotic agents.</description><identifier>ISSN: 2005-3711</identifier><identifier>EISSN: 1598-7876</identifier><language>kor</language><ispartof>Journal of Korean Neurosurgical Society, 2014, Vol.56 (1), p.34-41</ispartof><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,780,784,885,4023</link.rule.ids></links><search><creatorcontrib>Ko, Seok-Jin</creatorcontrib><creatorcontrib>Park, Kyung-Jae</creatorcontrib><creatorcontrib>Park, Dong-Hyuk</creatorcontrib><creatorcontrib>Kang, Shin-Hyuk</creatorcontrib><creatorcontrib>Park, Jung-Yul</creatorcontrib><creatorcontrib>Chung, Yong-Gu</creatorcontrib><title>Risk Factors Associated with Poor Outcomes in Patients with Brain Abscesses</title><title>Journal of Korean Neurosurgical Society</title><addtitle>대한신경외과학회지</addtitle><description>Objective : The purpose of this study was to describe the clinical characteristics, treatment outcomes, and prognostic factors in patients with brain abscesses treated in a single institute during a recent 10-year period.
