Psychiatric genetic counseling (pGC) can improve patient empowerment and self-efficacy. We explored the relationship between pGC and psychiatric hospitalizations, for which no prior data exist. Using Population Data BC (a provincial dataset), we tested two hypotheses: (1) among patients (>18 years) with psychiatric conditions who received pGC between May 2010 and Dec 2016 (N = 387), compared with the year pre-pGC, in the year post-pGC there would be fewer (a) individuals hospitalized and (b) total hospital admissions; and (2) using a matched cohort design, compared with controls (N = 363, matched 1:4 for sex, diagnosis, time since diagnosis, region, and age, and assigned a pseudo pGC index date), the pGC cohort (N = 91) would have (a) more individuals whose number of hospitalizations decreased and (b) fewer hospitalizations post-pGC/pseudo-index. We also explored total days in hospital. Within the pGC cohort, there were fewer hospitalizations post-pGC than pre- pGC (p = 0.011, OR = 1.69), and total days in hospital decreased (1085 to 669). However, when compared to matched controls, the post-pGC/pseudo index change in hospitalizations among pGC cases was not statistically significant, even after controlling for the higher number of hospitalizations prior. pGC may lead to fewer psychiatric hospitalizations and cost savings; further studies exploring this are warranted.

评估精神病遗传咨询对精神病住院治疗的影响

精神病遗传咨询（pGC）可以提高患者的自主权和自我效能。我们探讨了 pGC 与精神科住院治疗之间的关系，但此前尚无相关数据。使用 BC 人口数据（省级数据集），我们测试了两个假设：(1) 在 2010 年 5 月至 2016 年 12 月期间接受 pGC 的患有精神疾病的患者（> 18 岁）中（N  = 387），与 pGC 前一年相比，在 pGC 后的一年中，(a) 住院人数和 (b) 住院总人数将会减少； (2) 使用匹配队列设计，与对照（N  = 363，性别、诊断、诊断后时间、地区和年龄 1:4 匹配，并指定伪 pGC 索引日期）相比，pGC 队列（N  = 91）将有（a）更多的人住院人数减少，（b）pGC/伪指数后住院人数减少。我们还探讨了住院总天数。在 pGC 队列中，pGC 后住院次数少于 pGC 前（p  = 0.011，OR = 1.69），住院总天数也减少（1085 至 669）。然而，与匹配对照相比，pGC 病例中 pGC 后住院/伪指数变化并不具有统计学意义，即使在控制了之前较高的住院次数之后也是如此。 pGC 可能会减少精神病住院次数并节省费用；有必要进一步研究探索这一点。
