Previous analysis of jaw fracture hospitalisations in Western Australia (WA) indicated disproportionately high rates of hospitalisations for Aboriginal people. This study was to follow-up on the earlier analysis to determine if inequalities in terms of jaw fracture hospitalisation rates between Aboriginal and non-Aboriginal people have changed.
This study, done over a 10-year period from 1999/2000 to 2008/2009, aimed to determine rates of hospitalisations for jaw fractures in WA, trends over the 10-year period, and direct costs associated with these hospital admissions.
Hospitalisation data were obtained from the Western Australian Hospital Morbidity Data System (HMDS). Episodes were selected on the basis of an ICD10-AM code being S02.4 (Fracture of the malar and maxillary bones) and S02.6 (Fracture of the mandible). Self-reported Aboriginality were used to compare Aboriginal to non-Aboriginal populations. Estimated cost of care was determined for each episode using the national standard diagnostic-related group (DRG) average price.
Our findings indicate that inequalities between Aboriginal and non-Aboriginal people in terms of hospital admissions for jaw fractures exist in WA, and continued over a decade-long period. Higher fracture rates occurred amongst males, Aboriginal people, younger adult age-groups, those from low socioeconomic areas, and those from remote and very remote areas. The DRG cost per person for jaw fractures ranged between AUD $842 and $109,002, with a median cost of $4,965.
Hospital admission rates for the treatment of maxillary and mandibular fractures is very strongly divided along racial and socioeconomic lines in WA.
先前对西澳大利亚州（WA）颌骨骨折住院情况的分析表明，原住民的住院率高得不成比例。本研究旨在对早期分析进行跟进，以确定原住民与非原住民在颌骨骨折住院率方面的不平等情况是否发生了变化。
本研究在1999/2000年至2008/2009年的10年期间进行，旨在确定西澳大利亚州颌骨骨折的住院率、10年期间的趋势以及与这些住院治疗相关的直接费用。
住院数据从西澳大利亚州医院发病率数据系统（HMDS）获取。根据国际疾病分类第10版澳大利亚修订本（ICD10-AM）编码S02.4（颧骨和上颌骨骨折）和S02.6（下颌骨骨折）选择病例。使用自我报告的原住民身份将原住民与非原住民人群进行比较。使用国家标准诊断相关组（DRG）平均价格确定每个病例的护理费用估计值。
我们的研究结果表明，西澳大利亚州原住民与非原住民在颌骨骨折住院方面存在不平等，且这种情况持续了长达十年的时间。较高骨折率出现在男性、原住民、较年轻的成年人年龄组、社会经济地位较低地区的人群以及偏远和极偏远地区的人群中。颌骨骨折的人均DRG费用在842澳元至109,002澳元之间，中位数费用为4,965澳元。
在西澳大利亚州，上颌骨和下颌骨骨折治疗的住院率在种族和社会经济方面存在非常明显的差异。
