Suicide rates are often high in rural areas. Despite the strong association between deliberate self-harm (DSH) and suicide, few have studied rural residence and DSH. Self-poisonings dominate DSH hospital presentations. We investigate a previously reported association between rural residence and medical severity (defined as a subsequent medical/surgical inpatient stay) among emergency department presentations for medicinal self-poisoning (SP) to determine whether differences in agents taken, mental health service use or hospital-level resources explain the relationship.
A cohort of n=16,294 12-64-year olds presenting with SP to hospital emergency departments in Ontario, Canada, in 2001/2002 was linked to their service records over time.
The rural-medical severity association was best explained by differences in hospital resources; presenting to hospitals providing inpatient psychiatric services appeared to reduce medical/surgical inpatient stays in favor of psychiatric ones. Among those with a recent psychiatric admission, more intensive ambulatory psychiatric contact may be protective of a psychiatric inpatient stay subsequent to the SP presentation. Compared to nonrural residents, deliberate intent was identified less often in rural residents, particularly males.
The rural-medical severity association was best explained by disparities in the delivery systems serving rural and nonrural residents, important to rural suicide prevention efforts.
农村地区的自杀率通常较高。尽管蓄意自我伤害(DSH)与自杀之间存在密切关联,但很少有人研究农村居住情况与DSH之间的关系。自我中毒在DSH医院就诊病例中占主导地位。我们调查了先前报道的农村居住情况与药物性自我中毒(SP)急诊就诊时医疗严重程度(定义为随后的内科/外科住院治疗)之间的关联,以确定所服用药物、心理健康服务使用情况或医院层面资源的差异是否能解释这种关系。
2001/2002年在加拿大安大略省医院急诊科因SP就诊的16294名12 - 64岁人群组成的队列,随时间与他们的服务记录相关联。
农村与医疗严重程度之间的关联最好用医院资源差异来解释;在提供住院精神科服务的医院就诊似乎会减少内科/外科住院治疗,而倾向于精神科住院治疗。在近期有精神科住院史的人群中,更密集的门诊精神科接触可能会保护其在SP就诊后避免精神科住院。与非农村居民相比,农村居民(尤其是男性)蓄意意图的认定较少。
农村与医疗严重程度之间的关联最好用服务农村和非农村居民的医疗系统差异来解释,这对农村自杀预防工作很重要。
