Consultation-liaison in child psychiatry: a review of the past 10 years. Part I: Clinical findings

Pediatric Consultation-Liaison: Patient Characteristics and Considerations for Training in Evidence-Based Practices

Consultation-liaison services are an integral part of many pediatric hospital settings, yet characteristics of this patient population have not been extensively documented. The current study is a retrospective one-year chart review of the consultation-liaison service at a large pediatric hospital in the Southwestern United States. The purpose of this study is twofold: (1) to characterize this hospital's CL population and (2) to use these characteristics to identify preliminary evidence-based practices that should be considered for CL provider training. Identifying evidence-based practice elements that align with the characteristics of consultation-liaison patient populations may inform trainings for consultation-liaison staff. This would help to ensure that youth seen in hospital consultation-liaison services are getting the best available services, which is critical given the shortened time frame available to work with this patient population.

Pediatric Consultation-Liaison Psychiatry: An Update and Review

Background

In recent years, there has been an increasing burden of child and adolescent mental illness recognized in the United States, and the need for pediatric mental health care is growing. Pediatric consultation-liaison (C-L) psychiatrists are increasingly playing a role in the management of medical and psychiatric disease for pediatric patients. The field is a fast-moving one, with understanding of new neuropsychiatric disease entities; reformulation of prior disease entities; and new interdisciplinary treatments and models of care.

Methods

In this study, we aim to review recent advances in the field of pediatric C-L psychiatry, including new diagnostic entities, updated management of frequently encountered clinical presentations, and developments in systems of care.

Conclusion

The advances in pediatric C-L psychiatry are broad and serve to promote more streamlined, evidence-based care for the vulnerable population of psychiatrically ill pediatric medical patients. More work remains to determine the most effective interventions for the wide array of presentations seen by pediatric C-L psychiatrists.

Psychological burden of pediatric primary immunodeficiency

BACKGROUND

Primary immunodeficiency disorder (PID), being a chronic disorder, may increase the prevalence of psychopathologies, but there are few studies on the effect of disease-related factors on psychopathology in this population. The aim of this study was therefore to assess and compare three groups: children with PID who receive i.v. immunoglobulin treatment; children with juvenile idiopathic arthritis (JIA); and healthy controls with respect to their mental health status.

METHODS

Forty-four children with PID, 32 children with JIA and 30 healthy controls, underwent psychiatric evaluation. The Childhood Depression Inventory and the screen for child anxiety-related emotional disorders questionnaire were completed by the participants. The child behavior checklist was completed by the mothers of the participants. In addition, disease-related factors were identified.

RESULTS

The frequency of mood disorders between the three groups differed. There was no difference between the PID and JIA groups with respect to the prevalence of mood disorders and other psychopathologies. The disease-related factors were associated with the frequency of mood disorder in PID patients.

CONCLUSION

The rate of psychopathology was similar in patients with PID and JIA and higher than the controls. Some of the disease-related factors were associated with the frequency of mood disorders in the PID patients.

The Prevalence and Effect of Comorbid Cystic Fibrosis and Attention Deficit Hyperactivity Disorders on Hospitalizations: A Retrospective Analysis

Introduction: The prevalence of attention-deficit/hyperactivity disorder (ADHD) in pediatric cystic fibrosis (CF) patients is comparable to the general population, but the effects of ADHD on CF treatment and the outcomes have been minimally investigated.

Methods: Two cohorts were retrospectively reviewed, pediatric patients with comorbid CF/ADHD and patients with CF only. Each patient with CF/ADHD was age and sex-matched to a CF-only patient based on their most recent pulmonary office visit. Each patient was reviewed for forced expiratory volume in one-second percent predicted (FEV1%pred), body mass index (BMI) percentile, and hospitalizations for one year prior to the last pulmonary visit.

Results: A total of 624 patients with CF were identified, with 52 having co-morbid CF/ADHD (8.3%). Of those identified, 46 met inclusion criteria and were analyzed in the CF/ADHD cohort. The mean total hospital admissions between the CF/ADHD cohort and the CF-only cohort were not statistically significant (2.22 vs 1.834, p=.467). The difference between the BMI percentiles was not statistically significant (48.634 vs 38.634, p=.135). The difference between FEV1%pred was statistically significant at 84% for the CF/ADHD group and 74% for the CF-only group (p=.042).

Conclusion: The difference in total hospital admissions between the CF/ADHD cohort and the CF-only cohort did not reach statistical significance, but the study was underpowered. There was a significant difference between FEV1%pred between the two groups, in favor of the comorbid CF/ADHD population. More research is needed to further evaluate the effects of a comorbid ADHD diagnosis on outcomes in the CF pediatric population.

Zebras in the Forest: the experiences of Dual-Trained Child Psychiatrists and Paediatricians in Australia and New Zealand

OBJECTIVES

The objectives of this study were to examine the experiences of dual-trained child psychiatrists and paediatricians in Australia and New Zealand and inform the review of the Dual Fellowship Training Programme by the Royal Australian and New Zealand College of Psychiatrists and Royal Australasian College of Physicians.

METHODS

All dual-trained child psychiatrists and paediatricians and current trainees were electronically surveyed in 2015.

RESULTS

Seven out of eight specialists (88%) and four out of six trainees (67%) responded. Six (55%) completed or were undertaking training as part of the Dual Fellowship Training Programme. Most respondents entered dual training without difficulty, found the transition from paediatrics to adult psychiatry challenging, and were reassured by their decision to undertake dual training on reaching advanced training in child psychiatry. Benefits and downsides of dual training were noted during and following training. A significant proportion of specialists (55%) were working in hospital-based environments, especially consult liaison services, suggesting that they added long-term value to both the fields of child psychiatry and paediatrics.

CONCLUSIONS

The Dual Fellowship Training Programme remains a valuable vehicle for gaining skills in paediatrics and child psychiatry. There is support for its continuation by previous and current participants.

Validity, specificity, feasibility and acceptability of a brief pediatric distress thermometer in outpatient clinics

OBJECTIVE

Psychosocial distress is under-recognized in children with cancer and other serious medical illnesses because of a focus on pressing medical concerns.

AIMS

This study assessed the validity, inter-rater reliability, sensitivity/specificity, acceptability, and feasibility of administration of a pediatric distress thermometer (DT) designed to screen for the presence of psychosocial distress in youth with serious medical illnesses.

MATERIALS & METHODS

Two hundred eighty-one patient-caregiver-provider triads were enrolled from two hospital outpatient clinics. Patients diagnosed with cancer and other life-threatening diseases, caregivers, and providers completed the DT and a DT acceptability rating. Patients and caregivers completed standardized measures of anxiety, depression, pain, and fatigue. Providers completed a measure of disease severity. Data collectors completed a feasibility rating.

RESULTS

The DT was significantly correlated with both caregiver and patient reports of depression, anxiety, pain, and fatigue, exhibiting concurrent validity. Parent, child, and caregiver report demonstrated significant, moderate inter-rater reliability, with lower concordance between raters in the youngest age group. The DT is a sensitive instrument for screening of psychosocial distress when compared with the selected gold standard (Brief Symptom Inventory 18 depression subscale and the Children's Depression Inventory). The DT is not highly specific but quickly identifies those in need of further psychosocial assessment.

DISCUSSION

Screening, using an adapted pediatric DT, is valid, feasible, and acceptable to patients, caregivers, and medical providers across chronic medical illnesses.

CONCLUSION

As patient and caregiver reports are not always concordant, both patient and caregiver report of distress are important for the provider to obtain clinically meaningful information to guide interventions.

Psychosocial distress and functioning of Greek youth with cystic fibrosis: a cross-sectional study

Background

To assess psychosocial functioning and distress of children and adolescents with cystic fibrosis compared to healthy controls.

Methods

Thirty-six patients with cystic fibrosis aged 8–18 years (24 boys, mean age ± SD: 11.5 ± 2.6 years) and 31 sex- and age-matched healthy control subjects (18 boys, mean age ± SD: 12 ± 2.5 years) were enrolled in the study. In order to assess the self-esteem, social adjustment, and family functioning of these young people, the Culture-free Self-esteem Inventory, the Social Adjustment Scale–Self-Report, and the Family Assessment Device were administered. Emotional/ behavioral problems were assessed through the Youth Self Report and the Child Behavior Checklist given to both the subjects and their parents.

Results

No significant differences were found for self-esteem between the two study groups. Regarding social adjustment, children with cystic fibrosis reported significantly worse friendship and overall adjustment (P < 0.05). Moreover, no difference was found in the levels of family functioning between the two groups. No significant differences between the groups were found in emotional/ behavioral problems from the self-reports. On the contrary, parents of children with cystic fibrosis reported significantly higher levels of withdrawal/ depression, thought problems, and delinquent behavior (P ≤ 0.01) as compared to controls.

Conclusions

Children and adolescents with cystic fibrosis appear to be a psychosocially vulnerable group. A biopsychosocial approach should emphasize the assessment and treatment of the psychosocial distress of these patients alongside multiple somatic treatments.

Patients' opinions about suicide screening in a pediatric emergency department

OBJECTIVE

Understanding how children react to suicide screening in an emergency department (ED) can inform implementation strategies. This qualitative study describes pediatric patients' opinions regarding suicide screening in that setting.

METHODS

As part of a multisite instrument validation study, patients 10 to 21 years presenting with both psychiatric and nonpsychiatric complaints to an urban, tertiary care pediatric ED were recruited for suicide screening. Interviews with subjects included the question, "do you think ER nurses should ask kids about suicide/thoughts about hurting themselves...why/why not?" Responses were transcribed verbatim and uploaded into NVivo8.0 qualitative software for coding and content analysis.

RESULTS

Of the 156 patients who participated in the study, 106 (68%) presented to the ED with nonpsychiatric complaints and 50 (32%) presented with psychiatric complaints. The patients' mean (SD) age was 14.6 (2.8) years (range, 10-21 years), and 56% of the sample was female. All patients answered the question of interest, and 149 (96%) of 156 patients supported the idea that nurses should ask youth about suicide in the ED. The 5 most frequently endorsed themes were as follows: (1) identification of youth at risk (31/156, 20%), (2) a desire to feel known and understood by clinicians (31/156, 20%), (3) connection of youth with help and resources (28/156, 18%), (4) prevention of suicidal behavior (25/156, 16%), and (5) lack of other individuals to speak with about these issues (19/156, 12%).

CONCLUSIONS

Pediatric patients in the ED support suicide screening after being asked a number of suicide-related questions. Further work should evaluate the impact of suicide screening on referral practices and link screening efforts with evidence-based interventions.

A Review of Diabetes Mellitus–Specific Family Assessment Instruments

Family dynamics and attributes are increasingly recognized as affecting management of diabetes mellitus (DM); however, little research has been done on the validity and usefulness of family assessment instruments (FAIs). This article reviewed the literature that employs DM-specific FAIs and evaluates whether the instruments comprehensively captured family attributes/processes and were robust enough to be useful in understanding the relationship between family attributes/issues and DM-related health care. Studies using eight instruments were identified through a search of literature published from 1982 to 2010 and were analyzed with criteria derived from the measurement and family literatures. The findings of this study revealed that DM-specific FAIs yield useful data about family-related phenomenon; however, some domains of DM-specific care, such as family dynamics/functioning, were not overtly measured. Suggestions for improving DM-specific FAIs are provided and a rationale for why DM-specific and non-DM-specific FAIs is needed to fully measure family issues related to family dynamics/attributes on DM patient care.

Practice parameter for the psychiatric assessment and management of physically ill children and adolescents

This practice parameter describes the psychiatric assessment and management of physically ill children and adolescents. It reviews the epidemiology, clinical presentation, assessment, and treatment of psychiatric symptoms in children and adolescents with physical illnesses and the environmental and social influences that can affect patient outcome.

Late consequences of chronic pediatric illness

There are many challenges in coping with and adapting to life with a chronic disease, and increased survival cannot be assumed to be associated with increased quality of life. A recent systematic review shows there is wide variation in outcomes depending on the definitions and measurements used to estimate the prevalence of chronic health conditions, making the impact of disability on children's health and social functioning difficult to assess; various authors have called for an international consensus about the conceptual definition of chronic health conditions in childhood. It frequently is difficult to determine if problems in psychosocial functioning are caused by the underlying illness, by treatment, or by the resultant effects of either illness or treatment on physical growth or cognitive development. Assessment and treatment of mental health should be an integral component of the comprehensive care of chronically ill children and adolescents. Transition of care is an important process that addresses significant changes from child-oriented to adult-oriented care. Adults who have chronic health conditions should continue to be evaluated periodically for late consequences of the childhood illness and early medical care, and attention should be paid to their ongoing psychosocial, psychiatric, educational, and vocational needs.

The impact of newly diagnosed chronic paediatric conditions on parental quality of life

OBJECTIVE

Parental functioning and well-being are important aspects of a family's adaptation to chronic paediatric conditions. This study investigates the effects of diagnosis (cancer vs. diabetes/epilepsy) and time since diagnosis on parental quality of life (PQL).

METHODS

122 parents (66 mothers, 56 fathers), whose children were diagnosed and treated for one chronic disease, filled in the Ulm Quality of Life Inventory for Parents twice within the first three months after the initial diagnosis. The effects of diagnosis and time (1-2 weeks and 2-3 months after diagnosis) on PQL were analysed separately for mothers and fathers.

RESULTS

Parents of a child with cancer consistently reported lower PQL compared with parents of a child with diabetes/epilepsy. Only the fathers' well-being increased significantly within the first three months after the child was diagnosed for a chronic disease. However, in most of the PQL domains there was a persistent impairment within the time-frame of this study. Parents of children with a chronic disease were more satisfied with their family situation than healthy controls. Age of the child was positively correlated with PQL.

CONCLUSIONS

A diagnosis of cancer, especially in young children, has a strong negative effect on PQL. Measuring PQL in a preventive approach would help to identify vulnerable parents and to provide psychosocial support in time.

Practice patterns in pediatric consultation-liaison psychiatry: a national survey

The purpose of this survey was to describe the current status of pediatric consultation-liaison (C-L) services in the United States. A total of 144 pediatric C-L programs were surveyed, with a response rate of 33%. Financial and staffing constraints were cited as common problems; 61% of programs reported an increase in consultation requests over the past 5 years, however, 30% of services reported a decrease in funding. Collection rates for professional billings average 30%; 57% of services reported an increase in clinical service demands at the expense of teaching and liaison activities. Discussion includes recommendations based on the results of the survey.

Effects of psychotherapy for depression in children and adolescents: a meta-analysis

Serious sequelae of youth depression, plus recent concerns over medication safety, prompt growing interest in the effects of youth psychotherapy. In previous meta-analyses, effect sizes (ESs) have averaged .99, well above conventional standards for a large effect and well above mean ES for other conditions. The authors applied rigorous analytic methods to the largest study sample to date and found a mean ES of .34, not superior but significantly inferior to mean ES for other conditions. Cognitive treatments (e.g., cognitive-behavioral therapy) fared no better than noncognitive approaches. Effects showed both generality (anxiety was reduced) and specificity (externalizing problems were not), plus short- but not long-term holding power. Youth depression treatments appear to produce effects that are significant but modest in their strength, breadth, and durability.

Models and patterns of service in child and youth consultation-liaison services

OBJECTIVE

The aim was to examine referral pathways to child and youth consultation-liaison (C-L) services to identify patterns associated with demographic characteristics of patients, referral sources, the presenting problem and models of service.

METHOD

A case record review with a cross-sectional design. Data were extracted from the records of all patients referred to the C-L service for a 3 month period.

RESULTS

Adolescents were more likely to access mental health services through informal liaison services. Medical specialty areas that were inclusive of nursing and allied health, in both the request for service and initial response to the request, had higher frequencies of referral. There was no difference between the disciplines of medicine and social work in the frequency of referrals. However, medicine, social work and nursing differed in the number of staff who initiated the request for consultation, and the types of problems that were presented as reasons for referral.

CONCLUSIONS

Inclusive multidisciplinary models may facilitate the development of service relationships in paediatric hospital settings, due to the stability of staffing arrangements. The wider participation of allied health and nursing staff within paediatric hospitals may extend opportunities for the identification of mental health problems and enhance timely management of referrals.

Psychosocial liaison-consultation for the children who have undergone repair of imperforate anus and Hirschsprung disease

OBJECTIVE

The aim of this study was to investigate the psychological status of Japanese children with congenital anorectal malformation and their mothers to develop appropriate psychiatric interventions.

METHOD

The subjects comprised 50 children with congenital anorectal malformation aged 0 to 16 years and their mothers. The psychology of children aged 7 to 16 years was investigated by Kovacs' Children's Depression Inventory (CDI). The psychology of their mothers was assessed by Spielberger's State-Trait Anxiety Index (STAI) and Zung's Self-rating Depression Scale (SDS).

RESULTS

Depression was more marked in the children aged 12 to 16 years than in those aged 7 to 11 years according to the CDI. The mothers of preschool children showed higher levels of anxiety and depression than those of school-aged children, according to the STAI and SDS. Significant correlations between the CDI score of the children and the STAI or SDS score of the mothers were observed only among children aged 7 to 11 years.

CONCLUSIONS

The frequency of depression and anxiety among children with congenital anorectal malformation and that among their mothers was associated with the age of the child. Long-term postoperative psychosocial support for the children and their mothers may be required, taking into account the age of the child.

Redevelopment of a consultation-liaison service at a tertiary paediatric hospital

OBJECTIVE

This paper aims to describe the way a multidisciplinary team set out to redevelop a consultation-liaison (C-L) service at a tertiary paediatric hospital.

METHOD

The activities and processes in which the team members engaged were documented within a continuous quality improvement cycle. These activities included literature review, analysis of referral patterns, consultation with extant services, survey of referral sources and consultation with other tertiary paediatric services.

RESULTS

The outcomes of these initiatives were integrated into a re-formulated multidisciplinary team model dedicated to providing C-L services to the paediatric hospital. Significant challenges identified in the initial process were ongoing issues with caseload management and clarification of boundary demarcations.

CONCLUSION

There has been a gradual acceptance of the new C-L service by medical staff. The structure has resulted in a focused and coordinated C-L team that has contributed to innovations in the C-L process within the hospital.

Social Adaptation of Children with Congenital Fecal Dysfunction: From the Viewpoint of the Mother-Child Relationship

Excretory dysfunction associated with congenital anal anomalies (a generic term that includes anal atresia and Hirschsprung's disease) is presumed to greatly affect the psychology of the affected children. In this study, we conducted a survey on the psychological status of children with excretory dysfunction, and investigated the relationship between the affected children and their families in addition to their social life. Four children with fecal dysfunction due to a congenital anal anomaly and their mothers were interviewed. The results of psychological tests in the children and mothers along with our findings in the interviews with the children and mothers, were included in the data analysis. We found that regardless of the degree of excretory dysfunction, the child's state of mind was influenced by whether the mother exhibited warmth or criticism towards her child and whether there was a support system for the mother and child. We suggest that psychiatric consultation is necessary for these children.

Using dissertations to examine potential bias in child and adolescent clinical trials

The major youth psychotherapy meta-analyses have relied on published studies, which may have led to biased effect size estimates. To examine this possibility, the authors compared 121 dissertations with 134 published studies and found the following: (a) few differences on individual methodological variables, but, overall, stronger methodology in dissertations; (b) no differences in the steps taken to ensure treatment integrity; and (c) a mean dissertation effect size less than half that of published studies. The effect size difference remained robust across tests controlling for all reliable method differences. The findings suggest that dissertations are so strong, both methodologically and clinically, that they warrant inclusion in child psychotherapy meta-analyses and that previous meta-analyses, by excluding them, may have overestimated treatment effects.

Cognitive Therapy for Children, Young People and Families: Considering Service Provision

BACKGROUND

  This article presents a case for the development of cognitive therapy services for children, adolescents and their families.

METHOD

  The theoretical basis of cognitive therapy is described, and illustrated with a case. The article continues by exploring the context for service development, with a specific emphasis on evaluating the evidence-base for using cognitive therapy with children and adolescents. Consideration is also given to adapting cognitive therapy to the child's developmental level, and the evidence for the efficacy of cognitive-behavioural family approaches.

CONCLUSIONS

  The article concludes by arguing that there is a need to address mental health difficulties in young people by providing effective treatment approaches. The development of cognitive therapy services would support the further evaluation of this therapeutic approach.

La pédopsychiatrie de consultation–liaison intrahospitalière : étude prospective sur 215 interventions

The activity of child consultation-liaison psychiatry within the hospital can be defined as: the clinical, therapeutic and preventive care given by the staff members of the children psychiatric department, and their studies on pedagogy and research, in the other departments of the children hospital.

MATERIAL AND METHODS

Our study focused on the consultation-liaison interventions (N = 215) carried out in the Children Hospital of Tours (France) for 1 year (November 1999-October 2000): it dealt with their characteristics and those of the examined population. It aimed at describing qualitatively and quantitatively this activity and its evolution, by means of a prospective collection of information, and a comparison of some of them with researches carried on previously in the same setting.

RESULTS

Child consultation-liaison psychiatry plays a major part in pediatric hospital today. This activity increased by 33% since 1994. The nature of needs for pediatrics care has evolved, and crisis situations are now most dominant. Child psychiatry diagnoses are very varied: the most frequent ones concern adaptation troubles. The agreement on the suggested medical follow-up amounts to more than 50%.

Treating childhood depression over videoconferencing

Effective cognitive-behavioral treatments for childhood depression have developed over the last decade, but many families face barriers to such care. Telemedicine increases access to psychological interventions by linking the child and the clinician using videoconferencing (VC). The current study evaluated an 8-week, cognitive-behavioral therapy (CBT) intervention for childhood depression either face-to-face (F2F) or over VC. The telemedicine setup included two PC-based PictureTel systems at 128 kilibits per second (kbps). Success was defined by (1) decreasing depressive symptoms at similar rates in both the VC group and the F2F group and (2) demonstrating the feasibility of a randomized controlled trial in telemental health. Children were assessed for childhood depression using the mood section of the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present Episode (K-SADS-P). Twenty-eight children were randomized to either F2F or VC treatment. The participants completed the K-SADS-P and the Children's Depression Inventory (CDI) at pre- and post-treatment. The CBT treatment across the two conditions was effective. The overall response rate based on post-evaluation with the K-SADS-P was 82%. For the CDI total score, both the Time and the Group by Time effects were significant (p < 0.05). The interaction effect reflected a faster rate of decline in the CDI total score for the VC group. The study serves as a model for building on past research to implement a randomized controlled trial. This information provides persuasive research data concerning treatment effectiveness for clinicians, families, and funders.

Community clinic treatment of depressed youth: benchmarking usual care against CBT clinical trials

This study used a benchmarking strategy to evaluate the effectiveness of community psychotherapy for depressed youth relative to evidence-based treatment in clinical trials. Symptom trajectories of depressed youth treated in community mental health centers (CMHCs) were compared with trajectories of youth treated with cognitive-behavioral therapy (CBT) in clinical trials. Overall, outcomes of CMHC youth more closely resembled those of control condition youth than youth treated with CBT. Within the CMHC sample, ethnic minority status and low therapy dose were related to worse outcomes. However, when outcomes for Caucasian youth and youth receiving longer term services were examined, the CMHC sample still performed more poorly than youth treated with CBT. The findings support the value of developing, testing, and exporting effective therapies for depressed youth to community clinic settings.

Mechanisms of action in youth psychotherapy

BACKGROUND

In this review, we address a basic, but unanswered, question about psychosocial interventions for youth: How does psychotherapy work?

METHODS

We propose a framework for using mediation analysis to answer this question, and we review the youth therapy outcome literature for evidence on mediating mechanisms. We focus our review on clinical trials of empirically supported treatments for youth anxiety, depression, and disruptive behavior (N = 67).

RESULTS

Contrary to previous reports indicating that potential mediators are rarely assessed, 63% of the studies included measures of potential mediating mechanisms in their designs. Across treatment domains, percentages ranged from 22% of the studies of learning-based interventions for anxiety (i.e., systematic desensitization, modeling, and reinforced practice) to 91% of parent training investigations. Despite the rather extensive assessment of potential mediators, only six studies included any attempt to use the measures in a formal mediation test. Thus, despite the positive effects of treatments and surprisingly ample assessment of mediators, we still know remarkably little about how youth psychotherapies work.

CONCLUSIONS

We note common problems that hampered mediation testing (e.g., the design of many trials made it difficult to determine the temporal order of change in the mechanism and outcome), and we offer recommendations for improving study design to better assess mechanisms of therapeutic action. We also note the need to test mediation among referred youth treated in representative practice settings to complement the laboratory-based evidence on therapy mechanisms that prevails to date.
