Acute otitis externa (AOE) is a common inflammatory condition affecting the external ear that occasionally presents with persistent, severe pain, which may be unresponsive to first-line therapy and require assessment and treatment in the hospital setting.
To identify the microorganisms responsible for cases of otitis externa presenting to Wellington Hospital, New Zealand, over a five-year period between 2007 and 2011. We also aim to evaluate current management of this condition and to recommend future treatment options.
A five-year retrospective study, with data obtained from case notes and electronic records for all patients presenting with otitis externa to Wellington Hospital between 2007 and 2011.
Of three hundred and forty-seven cases identified, 144 were included in the study. Pseudomonas aeruginosa (P. aeruginosa) was the most common organism (46.5 per cent), while Staphylococcus aureus (S. aureus) was the second most common (31.9 per cent). Most patients received appropriate topical treatment. However, a significant number were treated with systemic antibiotics alone without adverse outcomes.
Pseudomonas aeruginosa is the most common microbe causing acute otitis externa in patients that require hospital level management in Wellington, New Zealand. In most cases, patients received appropriate topical therapy; however, it appears a large number received systemic antibiotic therapy without topical treatment. We recommend broad-spectrum topical antimicrobial therapy in all patients with uncomplicated AOE and culture-sensitive topical treatment with consideration of systemic antimicrobials for severe AOE requiring hospital admission.
急性外耳道炎（AOE）是一种常见的外耳道炎症性疾病，偶尔会出现持续性剧痛，可能对一线治疗无反应，需要在医院环境中进行评估和治疗。
确定2007年至2011年期间在新西兰惠灵顿医院就诊的外耳道炎病例的致病微生物。我们还旨在评估当前对该疾病的管理情况，并推荐未来的治疗方案。
进行一项为期五年的回顾性研究，数据来自2007年至2011年期间在惠灵顿医院就诊的所有外耳道炎患者的病历和电子记录。
在确定的347例病例中，144例纳入研究。铜绿假单胞菌（P. aeruginosa）是最常见的病原体（46.5%），而金黄色葡萄球菌（S. aureus）是第二常见的（31.9%）。大多数患者接受了适当的局部治疗。然而，相当一部分患者仅接受了全身抗生素治疗，且无不良后果。
在新西兰惠灵顿，需要医院级别管理的急性外耳道炎患者中，铜绿假单胞菌是最常见的致病微生物。在大多数情况下，患者接受了适当的局部治疗；然而，似乎有大量患者接受了全身抗生素治疗而未进行局部治疗。我们建议对所有无并发症的急性外耳道炎患者采用广谱局部抗菌治疗，对于需要住院治疗的严重急性外耳道炎患者，考虑采用对培养物敏感的局部治疗并联合全身抗菌药物。
