ABSTRACT Data about psychiatric problems among young people are scarce in the Gulf countries. This retrospective review of records describes the pattern of child and adolescent psychiatric disorders among patients consulting 3 child psychiatric clinics in Saudi Arabia during the year 2008. Most patients were referred from the public health sector (92.8%). Psychotropic drugs were prescribed for 86.2% of patients and psychotherapy for 55.2%. Maternal perinatal complications and other psychosocial stressors were noted in almost 45.8% of cases. Family history of psychiatric disorder was reported in 31.5% of patients. Psychiatric comorbidity was noted in 40.5% of cases while physical diseases were noted in 29.9%. The outcome was classified as unstable at the last consultation in 17.9% of cases. In a linear regression analysis the only factors significantly associated with unstable outcome were a higher load of symptoms (OR 2.64) and perinatal complications (OR 2.84).

Profil des troubles psychiatriques chez des enfants et adolescents consultant en établissements de soins psychiatriques pour enfants à financement public en Arabie saoudite

RÉSUMÉ Les données sur les problèmes psychiatriques des jeunes sont rares dans les pays du Golfe. Le présent examen rétrospectif des dossiers médicaux décrit le profil des troubles psychiatriques des enfants et des adolescents qui consultaient dans trois établissements de soins psychiatriques pour enfants en Arabie saoudite pendant l'année 2008. La plupart des patients venaient du secteur public de la santé (92,8 %). Des médicaments psychotropes ont été prescrits à 86,2 % et une psychothérapie à 55,2 % des patients. Des complications maternelles périnatales et d'autres facteurs de stress psychosociaux ont été observés dans presque 45,8 % des cas. Sur l'ensemble des patients étudiés, 31,5 % avaient des antécédents familiaux de troubles psychiatriques. Une comorbidité psychiatrique a pu être observée dans 40,5 % des cas et physique dans 29,9 %. à l'issue de la dernière consultation, 17,9 % des cas ont été classés comme instables. Dans une analyse de régression linéaire, les seuls facteurs significativement associés à une évolution instable étaient le nombre élevé de symptômes (O.R. 2,64) et les complications périnatales (O.R. 2,84).

Introduction

Approximately one-fifth of children and adolescents are afflicted annually by mental health problems, and their psychiatric morbidity accounts for 5 of the 10 leading causes of disability for those aged 5 years and above [1–3]. Despite this, mental health care for children and adolescents including development of adequate clinical services and programmes for staff training and research has received little attention from health planners in Saudi Arabia and other Arab nations as compared to more developed countries [4]. Notably there is a huge research database in the industrialized countries that assists in the development of good quality health care services for children and adolescents [5–10]. Most of the studies reported externalizing disorders such as attention deficit hyperactivity disorder (ADHD) as the most common, followed by internal disorders such as depression and anxiety plus co-occurrence of internal and external disorders [11–16]. Overall childhood psychopathology is the harbinger of similar (homotypic) or dissimilar (heterotypic) adult psychopathology.

In the Gulf countries the literature on psychiatric problems in the child and adolescent population is sparse [17–19]. There is no database on child and adolescent psychopathology from primary and secondary care in Saudi Arabia. Moreover, despite the establishment of child psychiatric clinics, no evaluation research has been carried out. This study in Saudi Arabia was an audit of the recorded sociodemographic and clinical information of children and adolescents attending publicly-funded child psychiatric clinics. The focus was on psychopathology, utilization patterns of services and treatment outcomes. It was hoped that the study findings would assist in further planning and development of the health care offered to children and adolescents with mental health disorders.

Methods

Study design

The study was a retrospective audit of the medical records of patients who attended child psychiatric clinics during the 1-year period 1 January to 31 December 2008. The records of both old and new patients were reviewed, i.e. patients who had consulted during earlier years but continued to visit into the year 2008 were also included.

Setting

Out of the 6 well-established Ministry of Health child and adolescent psychiatric clinics in Riyadh we selected 3 clinics randomly (by lottery) for data collection from 3 different cities: Al-Amal Complex for Mental Health in Riyadh, Maternity and Children Hospital in Buraidah and Al-Amal Complex for Mental Health in Dammam. These clinics accept patients aged ≤ 18 years and are staffed by well qualified, experienced psychiatrists.

Sample

All records of patients (n = 899) who consulted these clinics during the year 2008 were reviewed; 335 from Riyadh, 235 from Dammam and 329 from Buraidah. For this purpose a computer list of all child and adolescent patients who attended during the year 2008 was requested from the medical records section of the 3 treatment centres.

Data collection

The records were reviewed extensively to abstract data onto a pre-designed semi-structured sheet: background information (10 variables) and clinical information (26 variables). The data included were: sociodemographic variables, risk factors, mental health problems, comorbid physical conditions, utilization pattern of prescribed therapies, sources of referral and consultations, and treatment outcomes. Two investigators prepared the data collection sheet, then an independent investigator reviewed the items. Any disagreements were resolved and all 3 researchers agreed on the final list of items to be included.

Three psychiatrists from the selected clinics were briefed in a mini-workshop about how to abstract the relevant data from the files and note it on a pre-designed data collection sheet (available from the authors on request). During debriefing the field workers received clarification about any item on the sheet that they could not understand. Furthermore the chief investigators were available by telephone for consultation throughout the data collection phase.

Patients’ medical files contained multiple sources for data extraction, including consultant psychiatrists’ initial and follow-up evaluation notes, social workers’ follow-up reports, psychologists’ evaluation and IQ assessment sheets, in- and outpatient nursing observations, records of emergency visits, appended incoming referral notes, laboratory forms, vital sign documentation forms and internal and outgoing referrals. The clinics use Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for diagnosis, together with DSM guidelines for prescribing psychotropic drugs and psychosocial treatment modalities.

Data analysis

Data was entered into the computer and cleaned. Analysis was done using descriptive statistics. Risk ratios were estimated by comparing sociodemographic and clinical variables with overall outcome noted at the patient’s last visit and for this purpose all the selected variables were categorized into binary data. A P-value of 0.05 or less was considered significant.

Results

Sociodemographic variables

There psychiatric records of 899 patients who attended during the year 2008 were analysed. The mean age of the study patients was 9.2 (SD 3.7) years (range 1–20 years). These included 5 patients aged over 18 years who had continued their follow-up in the clinics even though they were eligible for referral to adult clinics for further diagnosis and treatment. Male patients outnumbered their female counterparts (55.5% versus 44.5%) and a majority of patients were Saudi nationals (92.2%) (Table 1).

About two-thirds of the children and adolescents were enrolled in different grades in special schools (63.6%). Most of the children were from cities (96.8%) with only 3.2% coming from rural areas.

Parental consanguinity, defined as marriage between close blood relatives, was noted for 49.8% of patients. The mean number of siblings of studied patients was 6.1 (SD 3.7) (range 1–18). The order of the patients among first-degree siblings was as follows: first child (17.8%), second (16.1%), third (16.0%), fourth (11.9%), fifth (8.0%), sixth (6.8%) and last (6.0%).

Consultation patterns and clinical variables

The key informant was most commonly the mother (81.2%); only rarely was the father (9.7%) or another person involved (6.2%) (data missing for 2.9%). Most of the children and adolescents (92.8%) had been referred by a public health facility, while only a minority came from the private sector (1.1%) (data missing for 6.2%). Patients were referred mainly for diagnosis and management (77.9% of cases) or a medical report (5.0%); in 17.0% of cases no reason was noted. The mean of number of visits made by the patients over the study period was 13.9 (range 1–35).

A history of antenatal, natal and postnatal complications concerning the mothers was noted for 45.8% of studied patients. These were most often linked to neonatal admissions to neonatal intensive care units of specialist hospitals, ranging from a few days to several days. This information was missing in 8.7% of patients’ records.

Psychological and neurological symptoms

The children presented with a variety of psychological and neurological symptoms (Table 2). The onset of symptoms was mostly during early childhood (≤ 5 years) (94.8%) rather than later (0.3%) (data missing in 8.7% of cases). The most common symptoms were hyperactivity (42.9%) poor scholastic performance (32.9%) delayed milestones (28.4%), anxiety and related manifestations (17.5%) attention and concentration difficulties (13.5%) and impulsivity (13.3%).

One or more previous psychiatric consultations at the study clinics before the period of this study were noted for almost half of patients (48.6%). Possible stressors, preceding or continuing, noted in half of patients records (50.8%) were related to a variety of factors including large and dysfunctional families, multiple marriages, financial problems, residential problems, parental problems and educational problems.

Diagnoses

The most common diagnosis made either at the index interview or decided later some time during follow-up or at discharge was mental retardation in 30.2% (borderline, mild, moderate, severe to profound). Less common were: anxiety disorders (16.1%); attention-deficit hyperactivity disorder (ADHD) (13.2%); autistic spectrum disorders (12.5%); and seizure disorders (9.7%). Rarer still were: mood disorders (4.2%); school refusal (4.2%); enuresis and encopresis (3.1%); psychosis (2.9%); and other disorders (Table 3).

Comorbid psychiatric disorders

The mental disorders mentioned above were co-occurring with another psychiatric disorder in 40.5% of cases. Most commonly this was cases of mental retardation coexisting with epilepsy, ADHD, autistic spectrum disorder, speech disorder or an incontinence problem. Some cases of anxiety were coupled with depression, school refusal or other problems (e.g. tics, stuttering). Three or more concurrent psychiatric disorders were reported in 11.6% of cases. The most common combination was mental retardation coexisting with epilepsy and ADHD, with autistic disorder and epilepsy, or with enuresis and encopresis.

Comorbid physical disorders

A concurrent diagnosis of a physical disorder was noted in the records for 29.9% of patients (20.1% had 1 disorder and 9.8% had 2 physical disorders). These were most commonly neurological syndromes or congenital malformations. As a corollary, the patients were noted to develop mental disability (18.7% of patients), physical disability (2.8%) and both (1.6%) (information missing in 77.0% of case records). Information about supportive diagnostic laboratory investigations and psychological testing carried out (mainly IQ and personality assessment) were available in 58.2% and 47.2% of case records respectively.

Family history

In 31.3% of medical records there was a family history of similar or different psychiatric disorders in family members (parents and siblings and second-degree relatives).

Drug and psychotherapy prescribing pattern

The psychotropic drug and psychotherapy prescribing pattern noted in the records of patients at the index interview and at the current/last evaluation is shown in Table 4. One or more psychotropic drugs were prescribed at the index interview for 86.2% of patients, mostly antipsychotics, anticholinergics, antidepressants plus selective serotonin reuptake inhibitors, psychostimulant derivatives, mood stabilizers, antiepileptic medications, benzodiazepines and hypnotics. Only 1 drug was prescribed in 64.9% of cases.

Psychotherapy was prescribed at the index evaluation for 55.2% of patients and at the last follow-up evaluation for 54.7% (more or less the same treatment). The therapeutic modalities included a wide variety of strategies, such as counselling, reassurance, behaviour therapy, family therapy, psychoeducation, social support, speech therapy, play therapy, rehabilitation programmes (e.g. training in activities of daily life, social skills development, cleaning, dressing, etc.) and cognitive–behaviour therapy.

Outcome

Outgoing referrals were noted in 27.2% of patients’ records for a variety of documented reasons, mainly medical problems such as acute infections with fever, self-inflicted injuries, drug-induced acute medical conditions (e.g. low blood pressure, dystonia etc.) Outcome was classified in the patients’ files as good or bad, stable or unstable, moderate improvement or no improvement, and controlled versus uncontrolled. A stable outcome at the last follow-up consultation was reported in 738 (82.1%) of medical files and unstable outcome in 161 (17.9%).

Table 4 shows the linear regression analysis of outcome (stable/unstable) according to various sociodemographic and clinical variables. There was no significant association of outcome with age, sex, nationality (Saudi/non-Saudi), educational level or residence (urban/rural). Family variables such as parental consanguinity, birth order, number of siblings and family history of psychiatric illness, were also not significant. Comorbidities (psychiatric or physical) also had not association. Only maternal perinatal complications and poly-psychopathological symptoms had a significant association with outcome. Patients with complications were nearly 3 times more likely to have an unstable course than their counterparts without perinatal complications (OR 2.84, 95% CI: 1.94–4.14). Patients with a high number of any symptoms (≥ 6 symptoms) were more than twice as likely to have a poor outcome compared with patients having fewer symptoms (OR 2.64, 95% CI: 1.59–4.43).

Discussion

This hospital-based study has given a broad view of the complex nature of mental health problems, service utilization and outcome measures in child and adolescent psychiatric clinics in Saudi Arabia. This study revealed the general sociodemographic profile of the children diagnosed with psychiatric disorders in the selected clinics. There was a nearly equal distribution of the sexes, albeit with a slight preponderance of males, a low level of education in two-thirds of patients, and a majority living in urban areas. Another survey of inpatient child and adolescent psychiatric referrals in a teaching hospital in Saudi Arabia revealed that most of them were less than 12 years and females outnumbered males [17] and in an epidemiological study of secondary-school children (aged 18–20 years) depression was more common among girls compared with boys [19].

The sources of incoming referral, almost all from public health settings (92.8%), and the types of outgoing referrals (internal and external consultations) and purposes of referrals, especially diagnostic and management, were consistent with other studies in this country [17–19].

According to this study a variety of psychopathological symptoms were recorded which clustered into: inattention, hyperactivity and impulsivity; delayed milestones, poor scholastic skills, delayed speech and incontinence; anxiety- and low mood; poor eye contact, social isolation and communication/speech difficulties; seizures; school refusal; and stereotyped behaviour. The most frequently noted principal diagnoses were mental retardation, ADHD, anxiety disorder, autistic spectrum disorder, seizures, depressive disorder, school refusal, enuresis/encopresis and psychosis; this diagnostic trend is more or less consistent with other hospital studies in Saudi Arabia [17–19]. In a community survey of 4-year-olds in the United States, similar symptom and diagnostic patterns—ADHD, anxiety disorders, depressive disorders and oppositional defiant disorder—were found [11].

The prevalence of psychiatric (40.5%) and physical (29.9%) co-morbidities among the studied patients was considerably higher than that reported in an epidemiological survey of a child and adolescent population elsewhere (overall co-morbidity rate of 6.4%) [11], which would be expected in a community survey. But these higher prevalence figures agree with the rate of comorbid disorders reported in a study of adults referred patients to psychiatric hospitals in Saudi Arabia (38% physical comorbidity rate) [20]. Evidently adult psychopathology may mirror the pattern of childhood psychopathology. The importance of this observation is that children and adolescents need comprehensive assessment in order not only to make the principal diagnosis but also to determine other comorbid psychiatric and physical disorders and their possible underlying causative factors. Treatment plans should address all recognized risk factors and disorders at their earliest stages in order to improve the overall outcome of patients.

The prescribing pattern of medications and non-drug interventions and utilization of other services is consistent with the relevant literature [17,21]. In studies of adults attending psychiatric treatment services in Saudi Arabia similar patterns of prescribing, which corresponded with the diagnostic categories, were reported [22,23]. The rate of polypharmacy, however, was higher in adult patients with mental disorders (85%) in another study [23] compared with that for children and adolescents in the present study (21.4% at the index evaluation). Prescribing of psychotherapy (alone or in combination with drug treatment), especially counselling, supportive therapy, family therapy, play therapy behavioural modification and psychoeducation, to children and adolescents with mental health problems is standard practice [24]. From our research it was difficult to comment on whether the prescribing of psychotropic drugs and psychotherapies was rational and unassociated with adverse effects. However, the finding that a stable outcome was recorded for more than 80% of studied patients is a reflection of the likelihood that the drug and non-drug interventions prescribed were appropriate.

There is considerable evidence about biological and psychosocial risk factors that may have an etiological role in mental disorders not only in children but also in adults. These include parental consanguinity, family history of mental disorders, large number of siblings, order of the child among siblings, parental marital problems, maternal multiparity, maternal perinatal problems, dysfunctional families, multiple marriages and parental relationship problems, financial difficulties, domestic violence and child abuse [14,25–28]. Although in the current study psychiatric and physical comorbidities were noted in a high proportion of cases (as mentioned above) and a family history of similar or dissimilar psychiatric disorder was reported in nearly one-third of children, among the factors studied only perinatal complications and number of symptoms were significantly associated with unstable outcome. It is recommended that perinatal services need to be improved further to reduce future complications including development of comorbid conditions

There were some limitations of the current study including the retrospective study design. However, it should be noted that there was no selection bias as all files recorded in the computer list were audited. Other strengths of the study included the selection of child psychiatric clinics with good data documentation by psychiatrists, multiple sources of recorded data and recent data notation. Nevertheless we suggest that the findings should be interpreted cautiously and it should be noted that data from a hospital-based study are not generalizable to the general child and adolescent population. Therefore a cross-sectional study using structured diagnostic schedule should be conducted to assess the child and adolescent mental health services in Saudi Arabia more comprehensively. Future research should also focus on the prevalence of specific childhood and adolescent mental disorders in the community nationwide.

In summary, this retrospective study provided a broad idea of pattern of sociodemographic profile, risk factors (especially perinatal complications and multiple symptoms), psychopathological symptoms and diagnoses, comorbid conditions, drug and non-drug prescribing and service utilization by child and adolescent patients consulting child psychiatric clinics in Saudi Arabia.
