The aim of this study was to determine if there is regionalization of orthognathic surgeries to teaching hospitals during the study period.
The Nationwide Inpatient Sample for years 2000-2008 was used. Every hospitalization that had an orthognathic surgery was selected. Patient and hospital level variables were examined. The odds of an orthognathic surgery procedure being performed in a teaching hospital over the study period was computed with the use of a multivariable logistic regression model.
During the study period, a total of 108,264 hospitalizations underwent orthognathic surgeries in the United States. The average age ranged from 27 years during the years 2006-2008 to 28.2 years during the years 2000-2002. After adjusting for multiple patient and hospital level factors, the year of procedure was not a significant predictor of increasing odds of an orthognathic surgery being performed in a teaching hospital.
There is no evidence of concentration of orthognathic surgical procedures in teaching hospitals.
本研究旨在确定在研究期间是否存在正颌手术向教学医院的区域化。
使用了 2000 年至 2008 年的全国住院患者样本。选择了每例接受正颌手术的住院患者。检查了患者和医院水平的变量。使用多变量逻辑回归模型计算了在研究期间在教学医院进行正颌手术的可能性。
在研究期间，美国共有 108264 例住院患者接受了正颌手术。平均年龄从 2006-2008 年的 27 岁到 2000-2002 年的 28.2 岁不等。在调整了多个患者和医院水平因素后，手术年份并不是在教学医院进行正颌手术的可能性增加的显著预测因素。
没有证据表明正颌手术集中在教学医院。
