This study identified potential risk factors associated with increasing hospital length of stay (LOS) in patients with odontogenic maxillofacial infections.
One hundred twenty-eight patients admitted to Brigham and Women's Hospital by the Division of Oral Surgery between October 1, 1984 and March 31, 1995 with a maxillofacial infection of dental origin were retrospectively identified by a medical chart review. Linear regression techniques were used to explain the relationship between patient admission characteristics and LOS. Variables considered included age, gender, infection location, admission white blood count (WBC), admission temperature, antibiotic treatment during hospitalization, attending surgeon, insurance class, operating room use (ORU), and preexisting medical conditions associated with chronic immunosuppression.
The following variables were found to significantly increase LOS: ORU (P = .007), preexisting medical conditions (P < .0001), admission temperature (P = .022), and deep infection (P = .063).
LOS is best predicted on the basis of underlying medical conditions and location of the infection.
本研究确定了与牙源性颌面感染患者住院时间延长相关的潜在风险因素。
通过病历回顾，对1984年10月1日至1995年3月31日期间因牙源性颌面感染入住布莱根妇女医院口腔外科的128例患者进行了回顾性研究。采用线性回归技术解释患者入院特征与住院时间之间的关系。考虑的变量包括年龄、性别、感染部位、入院时白细胞计数（WBC）、入院时体温、住院期间的抗生素治疗、主治外科医生、保险类别、手术室使用情况（ORU）以及与慢性免疫抑制相关的既往病史。
发现以下变量会显著延长住院时间：手术室使用情况（P = .007）、既往病史（P < .0001）、入院时体温（P = .022）和深部感染（P = .063）。
住院时间最好根据潜在的医疗状况和感染部位来预测。
