Psychiatric emergencies of minors with and without migration background

Summary Background The conditions of children and adolescents with migration background receiving emergency psychiatric care in Europe are not well known. Migrants usually attend regular psychiatric care less frequently than the autochthonous population. We therefore speculated that, being undertreated, they would be overrepresented among psychiatric emergency care patients. Methods We retrospectively analyzed the records of 1093 minors aged 4‑18 years treated during a period of three years at the psychiatric emergency outpatient clinic of the Department of Child and Adolescent Psychiatry at the Medical University of Vienna. Results More minors with migration background than natives consulted our emergency clinic. Most frequent reasons for referral were suicide attempts by Turkish patients, acute stress disorder in Serbian/Croatian/Bosnian and in Austrian patients. Psychiatric diagnoses like eating and personality disorders were mostly diagnosed in natives. We found gender specific differences between the groups. Conclusions The reasons for these differences possibly relate to deficits of adequate mental health-care in Austria, to intercultural and intrafamiliar conflicts related to acculturation distress in the migrant population. Prospective longitudinal studies focusing on the utilization of mental health care by the migrant children and the impact of the migration background on their mental health are needed for improving adequate culture-sensitive mental-health care for this population.


Background
Mental health disorders are commonly observed in all societies and age groups. Almost half of the psychiatric disorders begin in childhood and adolescence. The prevalence of psychiatric disorders in youth has steadily increased in the last decades and will probably continue to rise [1]. Detecting underlying causes seems of utmost importance because mental health problems may cause severe disability.
Poverty and migration background increase the risk of developing psychosocial disorders in children and adolescents [2,3]. Cultural, familial, and religious differences, migration and acculturation related distress, economic, health and education related disadvantages, limited acceptance by the host population, and limited participation in common cultural activities are among the most important causes for personal disadvantages of the migrant population, increasing the risk of mental health disorders [2,3], especially affective, anxiety, and psychosomatic disorders [4][5][6][7]. Limited language proficiency, and female gender further increase the experienced distress and the risk of developing affective disorders [8]. Restricted access to mental health care services will interfere with adequate medical treatment, and the risk of developing chronic disorders, affective, anxiety, psychosomatic disorders, and of substance abuse [9].
The prevalence of mental health disorders may be influenced by ethnicity. Turkish-speaking adults had the highest prevalence of depressive and/or anxiety disorders followed by Moroccans in a Dutch study [10]. Turkish speaking adolescents report more internalizing problems compared to their indigenous peers [10]. Increased acculturation stress, language problems, an unfamiliar local and social environment, low socioeconomic status and cultural dissimilarities may explain some of the health related differences between the migrant and the autochthonous population [5,7,[11][12][13].
Although the prevalence of psychiatric problems may be higher in the migrant population, children and adolescents with migration background are disadvantaged in accessing mental health care [14] because migrants label mental health problems as disgraceful and tend to ignore them. Being less articulate and facing low cultural competence of mental health professionals, they may avoid attending mental health care, medication and psychotherapy [4,5,[15][16][17][18][19]. This may lead to increased utilization of emergency psychiatric care [14,17,[20][21][22].
Although Austria is one of the wealthiest countries in the world, mental health care for children and adolescents is insufficient because of structural/ organizational problems and insufficient human resources [23]. This leads to insufficient psychiatric care and an increased risk of disabilities [23], especially for the migrant population [24]. The ethnic diversity of the Austrian population has rapidly increased in the last four decades. In 2010, 1,543,300 people with migration background lived in Austria, representing 18.6% of the total population. Particularly children and adolescents comprise a considerable proportion of the total migrant population. Based on the census of 2010, 582,000 or 36.9% of the migrant population were younger than 29 years, and 257,400 or 16.3% of the migrant population were children and adolescents aged less than 15 years [25]. 351,907 people with migration background lived in Vienna, representing 20.7% of the population in 2010. Two of the biggest migrant groups living in Vienna originate from Ex-Yugoslavia (6.8%, now Serbia/Croatia/Bosnia) followed by the Turkish speaking population (2.5%). Serbian/Croatian/Bosnian speaking people from Ex-Yugoslavia are now mostly in their second and third generation and probably better adapted to the Austrian cultural background, except for Bosnian refugees of the Balkan War in the early 90s when 100,000 people were killed or missing, and an equal amount of people, partly Muslims, fled from the country.
Due to the lack of data available on psychiatric health-care utilization, especially of the migrant population in Austria, we compared native Austrian children and adolescents with their peers originating from Turkey, and from former Yugoslavia and their reasons for consulting our emergency outpatient clinic. The objective of our study was to analyze differences concerning clinical reasons for referral and their background in the three study groups. We hypothesized 2 Psychiatric emergencies of minors with and without migration background K original article from data in international literature that migrant children and adolescents would be overrepresented in psychiatric emergency care compared to indigenous peers, and that we would find differences in the reasons of referral, psychiatric diagnoses, in gender, and the referring persons [8,26]. To our knowledge, this is the first study conducted in Europe explicitly comparing reasons for psychiatric emergency referrals of children and adolescents with and without migration background.

Methods
We retrospectively analyzed data extracted from the medical paper files of all patients, aged between 4-18 years, treated at the emergency outpatients' clinic of the Department of Child and Adolescent Psychiatry at the Medical University of Vienna between January 2008 and December 2010.
From the 1821 children and adolescents admitted to our emergency outpatient clinic during the study period, we only considered the data of 1718 patients aged between 4-18 years, and analyzed the files of 1093 patients, 800 native Austrian patients and 293 patients originating from Turkey (n = 130) and Ex-Yugoslavia (n = 163), excluding 625 patients with a different migration background. According to Statistic Austria, migration background is defined by at least one parent or grandparent not being born in Austria [25].
For patients having more than one reason for referral, we chose the most important reason. For patients who had more than one emergency consultation, only the first consultation was considered.
The Department of Child and Adolescent Psychiatry in Vienna is involved in the medical care of more than half of the Viennese children and adolescents with mental health problems; our study sample is therefore representative for the Viennese population.
We designed a specific data sheet for our retrospective data analysis. It summarizes patient history, socio-demographic data, like ethnicity, age, sex, reasons for referral, diagnoses, first attendance at our clinic, and referring person for the present contact. The data sheet contains 95 variables as we collected quite detailed information of the patients.
We used SPSS 20 software [27] for analyzing our data including descriptive methods, unpaired t-tests for analyzing differences between means, and chisquare statistics for analyzing differences of categorical variables. A p value ≤ 0.05 was considered to indicate statistical significance.
The Ethics Committee of the Medical University of Vienna approved the study protocol.

Study sample
More than half (53.4%, N = 918) of the patients consulting our emergency clinic had a migration background, 46.6% (N = 800) were native Austrians, 9.5% originated from former Yugoslavia, 7.6% from Turkey, and 36.4% from other countries like India, Pakistan, Iran, Iraq, Afghanistan, Egypt etc.
The majority of the patients (60.3%) had no previous psychiatric treatment, 57.2% of the Austrian, 70.8% of the Turkish and 66.9% of the Serbian/ Croatian/Bosnian patients attended the psychiatric emergency clinic for the first time (χ 2 = 12.0; p = 0.002). The remaining patients had already consulted our emergency clinic more than once because of acute problems.
We found significant gender differences (χ 2 = 114.3, p < 0.001) in the Austrian group but not in the groups

Psychiatric diagnoses
In 68.6% of the patients a psychiatric diagnosis was assigned ( Table 2). In the remaining patients the presented problems did not justify a psychiatric diagnosis or the attending physician did not assign a specific diagnosis. The most frequently assigned diagnoses were F 4 -neurotic, stress-related and somatoform disorders (24.9%) followed by F 3 -affective disorders (15.0%) and F 9 -behavioral and emotional disorders (13.4%).

Referring persons
Patients were most frequently referred to our emergency clinic by their social network (45.5%), 15.6% of the patients were referred by physicians, 12.4% by various institutions, and 9.1% of the patients came on their own, and in 17.6%, the referring person was not known.
There were differences among the three groups concerning the referring persons: Austrian and Serbian/Croatian/Bosnian patients were mostly referred 4 Psychiatric emergencies of minors with and without migration background K original article by their social network (48.0% vs. 50.9%), followed by physicians (15.0% vs. 20.2%). In the majority of the Turkish patients, the referring person was unknown (50.8%), followed by persons from the social network (23.1%; χ 2 = 122.5; p < 0.001).

Discussion
One of the main findings of our study was that children and adolescents with migration background were largely overrepresented at our psychiatric emergency outpatients' clinic. This result holds, even considering that the number of children in the migrant, and especially in the Turkish population is larger than in native Austrians (about the double, 1.3 vs. 2.5). Similar to previous studies, the majority of the patients consulted emergency psychiatric care for the first time [28]. In our study, more children and adolescents with migration background (about 2/3) compared to native Austrian children (50%) presented at the psychiatric emergency clinic for the first time.
There are possibly multiple causes responsible for these results: although there is a comprehensive insurance system for all people living in Austria, the lack of adequate, cultural and language competent diversity-care leads to diminished utilization of regular mental health care services by children and adolescents with psychic problems and migration background. In addition, culture and shame-related fears of psychiatric disorders might reduce the readiness to consult regular psychiatric services. Consequently the patients will consult emergency mental health care when the problems become overwhelming [14,24]. The significant gender differences -primarily females -for consulting emergency psychiatric care might be explained by the fact that especially adolescent girls with migration background were more affected by problems related to intrafamiliar conflicts and acculturation stress [21,23]. Adolescent girls are more strictly controlled by their families and were reported to get less psychological care compared to their male peers [20,21,26]. In addition, male youths frequently present externalizing disorders leading to problems earlier in life, psychiatric referrals and treatment whereas internalizing disorders, more predominant in (adolescent) girls, are more easily neglected.
Another major finding of our study was that Serbian/Croatian/Bosnian and Turkish speaking children and adolescents were referred more frequently than natives for suicide ideation and attempts. Comparing similar studies in youth [29], suicidality was the most frequently reported reason for referral to emergency clinics in other countries. In our sample this was only observed in Turkish children who probably suffer more from acculturation stress [2,21] because of the larger cultural and religious differences between the culture of origin and the dominant host culture [30], and probably because the Serbian/Croatian wave of immigration started about 10-15 years earlier than the Turkish wave in Austria, enabling nearly a whole generation to adapt to the (probably less different) host culture. In addition, German language problems which are more pronounced in the Turkish compared to the former Yugoslavian population [24], and the reduced availability of qualified Turkish speaking interpreters (often the siblings) may be held responsible for more data lacking data in the Turkish population.
We also found differences concerning the reasons for referral: Austrian children consulted the emergency psychiatric outpatient clinic most frequently for acute stress and behavioral disorders. Turkish children and adolescents were most frequently referred for suicidal attempts and acute stress disorder, and Serbian/Croatian/Bosnian youth were most frequently referred for acute stress disorder followed by suicidal attempts. There were significant differences in the reasons of referral not only between native and migrant patients and also between the two migrant groups. In agreement with our results, other studies reported that for minors with migration background the usual source of referral to the mental health services was medical experts, teachers or social workers [31].
The distribution of personality disorders was different in the three populations. This may be attributed to the fact that (Austrian) patients with this disorder usually are well-known recurrent clients at the emergency clinic, and when they get into suicidal crises, they will be attributed the primary diagnosis whereas in the migrant population who mostly appear for the first time at the emergency service, this diagnosis is not attributed with lightly, especially in younger adolescents. In addition, the fact that many migrant patients consulted the emergency clinic because of suicidal ideation or attempts may possibly be explained by the larger differences in values between the culture of origin and the host culture [2,31], leading to emotional distress, and especially Turkish patients do not possess other exit strategies than a suicide attempt to escape from intrafamiliar, intra-and interpersonal conflicts [2,5,21,32].
Our observation of no significant gender differences in psychiatric diagnoses in Turkish compared to a female overrepresentation in Austrian patients is confirmed by previous studies e. g. [33].

Conclusion
Migrants can be considered a vulnerable group in the health-care systems [14,34]. Numerous structural, political, socio-cultural as well as migration-specific factors lead to reduced utilization of health-care resources [11,14] in Austria and in other European countries [35]. In addition, the health-care needs of children and adolescents with migration background are different compared to their autochthonous peers [34,36]. Offering adequate health-care services to young people with migration background is difficult because specifically trained, language-proficient medical staff are not ubiquitously available.
Although the number of immigrant children and adolescents living in European countries is high, studies analyzing mental health problems of migrant children and adolescents are rare [7,14]. The majority of the available studies focus on physical illnesses like infectious diseases or dental health problems [34].
As a consequence of these deficits, culture-specific symptoms of patients with migration background may be misinterpreted and may lead to inadequate diagnoses and treatment [14,37]. This is especially true for psychiatric disorders [37]. Therefore, growing awareness of the different cultural background and values, on the diagnosis and treatment of migrant mental health disorders, and especially longitudinal studies are needed in order to provide adequate, appropriate, and preventive patient-centered care to this population and to decrease emergency care consultations [7,13,14,33,36,38]. In addition, preventive measures should be established particularly in the natural settings of young people, for example in schools [39].

Limitations
The present study is based on a retrospective analysis; therefore missing data could not be replenished. During an acute crisis, the patient history may not be ascertained in detail, therefore data about socio-demographic background were missing in more than half of the patients. More data were missing in patients with migration background probably because of insufficient language skills of the patients, their parents, and the caring physicians. Missing data are a relevant problem because of a possible selection bias. We analyzed psychiatric emergencies of children and adolescents originating from Turkey and former Yugoslavia living in Vienna. Therefore, the results cannot be generalized to other groups of migrants living in Austria.
