This study examined whether sociodemographic factors, including distance to hospital, were associated with differences in the diagnostic interval and the treatment interval for colorectal cancer in northern Sweden.
Data were retrieved from the Swedish cancer register on patients (n = 446) diagnosed in three northern regions during 2017-2018, then linked to data from Statistics Sweden and medical records. Also, Google maps was used to map the distance between patients' place of residence and nearest hospital. The different time intervals were analysed using Mann-Whitney U-test and Cox regression.
Differences in time to diagnosis were found between groups for income and distance to hospital, favouring those with higher income and shorter distance. The unadjusted regression analysis showed higher income to be associated with more rapid diagnosis (HR 1.004, CI 1.001-1.007). This association remained in the fully adjusted model for income (HR 1.004, CI 1.000-1.008), but not for distance. No differences between sociodemographic groups were found in the treatment interval.
Higher income and shorter distance to hospital were in the unadjusted models associated with shorter time to diagnosis for patients with CRC in northern Sweden. The association remained for income when adjusting for other variables even though the difference was small.
本研究旨在探讨在瑞典北部，社会人口因素（包括到医院的距离）是否与结直肠癌的诊断间隔和治疗间隔存在差异有关。
从 2017 年至 2018 年在瑞典北部三个地区诊断的患者的瑞典癌症登记处获取数据（n=446），然后与瑞典统计局和医疗记录的数据进行关联。还使用谷歌地图绘制了患者居住地和最近医院之间的距离。使用 Mann-Whitney U 检验和 Cox 回归分析了不同的时间间隔。
在收入和到医院的距离方面，不同组之间的诊断时间存在差异，收入较高和距离较短的患者具有优势。未调整的回归分析显示，较高的收入与更快速的诊断相关（HR 1.004，CI 1.001-1.007）。这种关联在收入的完全调整模型中仍然存在（HR 1.004，CI 1.000-1.008），但对于距离则不然。在治疗间隔方面，社会人口群体之间没有差异。
在未调整模型中，较高的收入和较短的到医院距离与瑞典北部 CRC 患者的诊断时间较短有关。在调整其他变量后，收入的相关性仍然存在，尽管差异较小。
