Many studies are searching clinical and social-demographic predictive factors of the management options in psychiatric emergency. The greater part of these researches are published in US and are seeking about patients and about conditions of psychiatric practice different of the European circumstances. Such differences have motivated us to perform a comparison between the characteristics of the native Swiss and of the foreign patients in the psychiatric emergencies. The other aim of the study was to detect, if differences are proven, some predictive factors of their management strategies. This study describes the social-demographic and clinical characteristics of a sample of 1 028 unduplicated consultations and investigates possible relationships between these clinical characteristics and different management strategies, with a particular focus on the foreign patients, covering 46.5% of all consultations. Because quite half of the psychiatric emergency visits occur with foreigners, it plays a potentially important role in searching the disparities in diagnosis and management. To verify these differences, we studied two specific questions: 1) are there nationalities differences in diagnosis with respect to the Swiss native population, and 2) are there nationality differences in management of patients visiting a psychiatric emergency service?
Demographic and clinical data were obtained prospectively from the psychiatric emergency service of Geneva, located in the county general hospital, during a 13 weeks period. The study involved all patients aged between 18 and 65 years, inhabitants of county of Geneva-Switzerland, presented at the psychiatric emergency service of the general hospital. To limit the bias of screening the chronic patients, we have included only once, at the first examination, the patients with more than one emergency consultation in the considered interval.
As a general trend, the probability for the foreign patients to consult the emergency psychiatrist is greater than for the Swiss natives: OR=1.44, p=0.000. The social-demographic factors show significant differences between the foreigners and Swiss population: the immigrating population is younger, more active and clustered to a familial structure. Despite the availability and use of the same clinical criteria, foreign patients are disproportionately differently diagnosed, with less alcohol abuse (14.7% for foreigners versus 23.9% in the Swiss population), less personality disorders (8.1% versus 13%), more affective disorders (54.7% versus 43%) and more anxious disorders (18.4% versus 12.3%). Furthermore, on the sum of all diagnoses, the single statistically significant difference in management is found in respect to the recommendation for a Short-term Therapeutic Centre , done more frequently for the foreigners: 15.5% versus 11.3%. Some immigration-related predictive factors of diagnosis and management are found and detailed.
The apparent habit of the foreigners to appeal to the hospital emergencies could be, at least partially, due to a minority or cultural factor: the patients seem to be easily appealing to a great hospital rather than to a territorial policlinic by failure to find a psychiatrist into the Swiss health network. This hypothesis is to be confirmed by further studies. The inexistence of significant differences in management of the patients with the same diagnosis between the two patient groups suggests the equality of resources spent for the two patient groups. The main methodological limit of this study consists of the gathering of different immigrated nationalities in a unique patient group in order to find, if any, significant differences in comparison to the Swiss patients, whereas may be matter of heterogeneous populations.
These observations suggest that further researches are needed to clarify the decision-making process in diagnosis and patient management in psychiatric emergency department, especially for foreigners, and to distinguish different cultural groups rather than different nationalities. The reassessment of all patients with their clinical evolution and the allocated health resources could lead to the question on the relevance of health management decisions in psychiatric emergency circumstances, as well as to the question on the influence of the foreigner status on therapeutic decisions.
许多研究正在探寻精神科急诊中管理方案的临床及社会人口学预测因素。这些研究大多发表于美国,所探寻的患者及精神科诊疗情况与欧洲情形不同。此类差异促使我们对瑞士本国患者与外国患者在精神科急诊中的特征进行比较。该研究的另一目的是,若证实存在差异,找出其管理策略的一些预测因素。本研究描述了1028例无重复诊疗案例样本的社会人口学及临床特征,并调查了这些临床特征与不同管理策略之间可能存在的关系,特别关注外国患者,其占所有诊疗案例的46.5%。由于精神科急诊就诊患者中有近一半是外国人,这在探寻诊断及管理方面的差异中可能发挥着潜在的重要作用。为验证这些差异,我们研究了两个具体问题:1)与瑞士本国人口相比,诊断方面是否存在国籍差异?2)前往精神科急诊服务机构就诊的患者在管理方面是否存在国籍差异?
在13周期间,前瞻性地从位于县综合医院的日内瓦精神科急诊服务机构获取人口统计学和临床数据。该研究纳入了所有年龄在18至65岁之间、居住在瑞士日内瓦县、到综合医院精神科急诊服务机构就诊的患者。为限制筛选慢性病患者的偏差,我们仅在首次检查时纳入了在考虑时间段内有多次急诊诊疗的患者一次。
总体趋势是,外国患者咨询急诊精神科医生的概率高于瑞士本国患者:比值比(OR)=1.44,p = 0.000。外国人和瑞士人群在社会人口学因素上存在显著差异:移民人口更年轻、更活跃且倾向于家庭结构。尽管使用相同的临床标准,但外国患者的诊断差异显著,酒精滥用较少(外国人为14.7%,瑞士人群为23.9%),人格障碍较少(8.1%对13%),情感障碍较多(54.7%对43%),焦虑障碍较多(18.4%对12.3%)。此外,在所有诊断的总和方面,在管理上唯一具有统计学显著差异的是对短期治疗中心的推荐,外国患者的推荐频率更高:15.5%对11.3%。发现并详细阐述了一些与移民相关的诊断和管理预测因素。
外国人明显倾向于前往医院急诊,这至少部分可能是由于少数群体或文化因素:患者似乎因在瑞士医疗网络中找不到精神科医生,而更容易前往大型医院而非地区性门诊。这一假设有待进一步研究证实。两组患者中相同诊断患者在管理上不存在显著差异,这表明为两组患者花费的资源相当。本研究的主要方法学局限在于,为了找出与瑞士患者相比是否存在显著差异,将不同移民国籍的患者归为一个独特的患者群体,而这些群体可能存在异质性。
这些观察结果表明,需要进一步研究以阐明精神科急诊科诊断和患者管理的决策过程,特别是针对外国人,并区分不同文化群体而非不同国籍。根据患者的临床进展和分配的医疗资源对所有患者进行重新评估,可能会引发关于精神科急诊情况下医疗管理决策相关性的问题,以及外国人身份对治疗决策影响的问题。
