Objective The aim of the current paper is to analyse time trends of non-fatal suicidal behaviour (NFSB) and its repetition at the Gold Coast in 2005-2015. Methods Data on presentations for NFSB were obtained from the Emergency Department (ED) Information System. Potential cases were identified through keyword searches, which were further scrutinised and coded. Annual person-based age-standardised rates for NFSB were calculated. Chi-square test, Poisson regression and Cox proportional hazards regression were used.
There was a significant increase in the age-standardised rates of NFSB for males (incidence Rate Ratio = 1.05; 95% confidence interval (CI): 1.04-1.07) and females (iRR = 1.06; 95% CI: 1.04-1.07). Age-specific rates showed significant increases for all age groups, except 25-34 and 55+ for females. Different types of poisoning were the predominant method of NFSB (poisoning only - 61.7% of episodes), followed by cutting (23%). Within the first year after the index episode, 13.4% of subjects repeated NFSB. Multivariate Cox regression model showed that sex, age and method predicted repetition.
The increasing trends of NFSB and relatively high repetition rates emphasise the need for preventative actions. Monitoring of NFSB at the ED level should be further extended in Australia.
目的 本文旨在分析2005 - 2015年黄金海岸非致命自杀行为（NFSB）的时间趋势及其复发情况。方法 从急诊科（ED）信息系统获取NFSB就诊数据。通过关键词搜索识别潜在病例，并进一步审查和编码。计算NFSB的年度基于人群的年龄标准化率。使用卡方检验、泊松回归和Cox比例风险回归。
男性（发病率比 = 1.05；95%置信区间（CI）：1.04 - 1.07）和女性（发病率比 = 1.06；95% CI：1.04 - 1.07）的NFSB年龄标准化率显著增加。除女性25 - 34岁和55岁以上年龄组外，所有年龄组的年龄特异性率均显著增加。不同类型的中毒是NFSB的主要方法（仅中毒 - 61.7%的发作），其次是切割（23%）。在首次发作后的第一年内，13.4%的受试者复发NFSB。多变量Cox回归模型表明，性别、年龄和方法可预测复发。
NFSB的上升趋势和相对较高的复发率强调了预防行动的必要性。在澳大利亚，应进一步扩大在急诊科层面对NFSB的监测。
