There are variations in the duration of intravenous antimicrobial treatment and timing for transition to oral antimicrobials among infectious disease (ID) specialists in different countries. Future randomized controlled trials (RCTs) are necessary to determine the optimal treatment for brain abscess.
To examine antimicrobial management of brain abscess and prioritize future trials. Self-administered, Internet-based survey of practices for treatment of community-acquired bacterial brain abscess among infectious diseases (ID) specialists in France, Sweden, Australia, and Denmark during November 2019. Respondents were also asked to rank future randomized controlled trials (RCTs) from 1 (high priority) to 6 (low priority). 310 ID specialists (45% female) from France (35%), Sweden (29%), Australia (25%), and Denmark (11%) participated in the survey, primarily from university hospitals (69%) with an on-site neurosurgical department (61%). Preferred empiric intravenous (IV) antimicrobials were cefotaxime (154/273, 56%) or ceftriaxone (68/273, 25%) combined with metronidazole for a median of 4 weeks (IQR 4-6), 4 weeks (IQR 2-4), and 6 weeks (IQR 4-6) for aspirated, excised, and conservatively treated patients, respectively. Early transition to oral antimicrobials (i.e., < 4 weeks of IV antimicrobials) was used by 134/269 (50%), whereas consolidation therapy with oral antimicrobials after a standard IV regimen (i.e., 4-8 weeks) was used by 123/264 (47%). Median prioritization scores for future RCTs were as follows: 1 (IQR 1-2) for an early transition to oral antimicrobials and duration of therapy, 3 (IQR 2-4) for comparisons of antimicrobial regimens, use of adjunctive dexamethasone, and neurosurgical aspiration versus excision, and 4 (IQR 3-5) for intracavitary antimicrobial instillation and drainage, and for prophylactic anti-epileptic therapy. Willingness to include patients into RCTs reflected prioritization scores. Duration of intravenous antimicrobial treatment and use of oral antimicrobials varies substantially among ID specialists. RCTs are needed to define optimal treatment of brain abscess.
