A national state of emergency in children’s mental health was declared by the American Academy of Pediatrics, American Academy of Child and Adolescent Psychiatry, and Children’s Hospital Association on October 19, 2021 [1]. The COVID-19 pandemic has disrupted the education of nearly all 55 million kindergarten through 12th grade students in the United States [2, 3]. The recent US Surgeon General’s Advisory on protecting youth mental health [4] underscores rising child mental health needs placing an unprecedented strain on the child mental health care system [5,6,7]. Together, these forces have been an impetus for child and adolescent psychiatrists and allied professionals to think critically about how to better leverage clinical informatics to meet the mental health needs of children [8] and learn collectively about the growing role of technology-driven and technology-informed modes of practice in supporting quality of child mental health care [9].

There have been two parallel trends over the last decade, both of which have been accentuated by the pandemic. The first is emotionally palpable to clinicians working with children and families: the rates of childhood mental health concerns and suicide have risen steadily throughout the decade [10]. By 2018, suicide reached the second leading cause of death among young people aged 10 to 34 years [11], and during 2020 there were dramatic increases in emergency department visits for suicide-related behavior among youth [12, 13]. The second trend is an extremely rapid growth in health data, including patient access to data, and health care decision-making based on health information technology. However, the combination of rising child mental health care needs and the rapid advancement of digital health technologies is also coupled with a significant divide between child psychiatry and training in clinical informatics [14]. Notably, few child psychiatrists have had formal training or developed skillsets to adapt, develop, or critically evaluate the use of electronic health records (EHRs) at point of care, or to interpret the growing body of scientific literature leveraging EHRs to generate evidence for child psychiatry research [15].

This is a critical time for child mental health care. There is a growing recognition of the role of health data in changing clinical practice. There is also a crucial need to narrow the research to practice gap and to connect the traditionally siloed fields of child psychiatry and clinical informatics. In this context, we aim to discuss some of the potential applications of informatics to child mental health and to show how these two fields may be bridged in practice and training. We argue that better connecting these two fields could offer critical pathways for attending to the current crisis in child mental health. At the population level, improving the methods and infrastructure through which child mental health data are routinely collected and subsequently analyzed may help improve public health surveillance, identify inequities and gaps in access to care, and generate new knowledge in the discovery and management of child mental health conditions. At the individual child level, adapting the EHR as a tool for health delivery provides an important avenue to support measurement-based care, improve communication between providers, patients, and families, and mitigate clinician burnout and fatigue. However, the promise of bridging these fields must be tempered with an understanding of the feasibility within the context of workforce shortages, need for protection of health information, potential for biases, and challenges ahead.

Clinical Informatics

Clinical informatics is the application of informatics (i.e., the study of computational systems for data storage and retrieval) and information technology (i.e., computing technology used in the acquisition, storage, manipulation, display, and transmission of data) to deliver health care services [16, 17]. Clinical informatics was recognized in 2013 as a formal subspecialty by the American Board of Medical Specialties (ABMS) with over 1,800 board-certified physicians who have primary board certification in another specialty [18]. Physicians who practice clinical informatics collaborate with other health care and information technology professionals to design, implement, analyze, and evaluate information and communication systems to enhance individual and population health outcomes [17]. Physician informaticists leverage their knowledge of patient care combined with an understanding of informatics concepts and tools to lead measurement of patient and provider needs. They characterize, evaluate, and refine patient care processes, develop clinical decision support tools, and lead the design and continuous improvement of clinical information systems [19].

In its ideal form, clinical informatics functions to accelerate and support a learning health system, defined by the Institute of Medicine as a system “in which knowledge generation is so embedded into the core of the practice of medicine that it is a natural outgrowth and product of the healthcare delivery process and leads to continual improvement in care” [20, 21]. This occurs through several iterative mechanisms including use of EHRs to systematically gather health data, generate evidence to improve care, and deploy point-of-care tools in turn informed by data and evidence [22, 23].

EHR-Based Applications for Child Mental Health

Since Torous et al. [24] advocated for training in clinical informatics in psychiatry, the field of mental health informatics has continued to grow, catalyzed by advancement of digital health technology and rising clinical needs. Examples of applications of clinical informatics in child psychiatry include point-of-care tools (e.g., embedding the Columbia-Suicide Severity Rating Scale in the clinician workflow of an EHR), patient-facing portals and patient access to medical records (e.g., open notes), public health surveillance and identification of areas of clinical need (e.g., tracking child mental health acute care utilization during the COVID-19 pandemic), and predictive analytics (e.g., leveraging large multi-site EHR datasets to inform personalized suicide risk prediction) (see Table 1).

At the onset of the COVID-19 pandemic, numerous studies leveraged data from EHRs to understand public health trends in child health. These in turn unearthed a disproportionate rise in child mental health need, inequalities in care delivery and access, and changes to health care delivery via telehealth [12, 13, 26]. Shifts in child mental health care delivery during the pandemic also brought a new need for provider tools such as EHR-telehealth integration, conversion of residual paper documentation (e.g., consent forms) to EHR-integrated formats, increased communication between mental health and other medical providers, and flags and banners to identify isolation precautions and vaccination status [27].

While these efforts are laudable, the tremendous strain of the pandemic has also exposed the ways in which collection and analysis of health data is not yet adapted for child mental health care. For example, analysis of public health trends in child mental health using EHRs often relies on data stored in structured fields, most commonly, International Classification of Disease codes. However, structured data alone is often inaccurate in the discovery of mental health and suicide-related visits [28, 29]. There has also been scarce adaptation of natural language processing and other text processing methods to detect child mental health conditions from large-scale EHRs [30]. Although diagnostic classification systems have supported the categorization of child mental health conditions from billing and diagnostic codes as exampled by the Child and Adolescent Mental Health Disorders Classification System [31], there is a lack of validated psychiatric comorbidity indexes for child mental health conditions equivalent to existing medical comorbidity indexes such as the pediatric complex chronic conditions (CCC) classification system [32].

In an article in this issue, Agrawal [33] quoted D.H. Lawrence, “What the eye doesn’t see and the mind doesn’t know, doesn’t exist,” in discussing the inclusion of social history components of the medical note. Kronsberg [34] also pointed to the rising need to educate trainees on social determinants of health. Information on the social history, for example, can become “invisible” at a population level when stored in unstructured (free text) fields of EHRs. Educational variables (grade, type of school, receipt of special education services) are almost entirely omitted from structured data fields, and developmental monitoring and screening measures are variably encoded in structured and unstructured fields. Commonly used structured EHR data elements and examples of elements potentially of interest to child psychiatrists are presented in Table 2.

In fact, common data models standardizing the storage and curation of data from EHRs have had scarce input from child mental health providers, and they often do not specify storage or encoding of social determinants of health relevant to child mental health care. In turn, it is difficult to leverage EHRs to answer questions about the role of school closures and child mental health utilization or about the disproportionate impact of social disruptions, adversity, and school-related mental health care gaps during the COVID-19 pandemic on children from communities of color. As social determinants of health are increasingly recognized as a core component of EHR data, meriting extraction and text analysis [36, 37], academic child psychiatrists have an important opportunity to use their clinical knowledge to improve systematic discovery of developmentally-specific antecedents of child mental health outcomes already being documented in EHRs).

To support a vision of a learning health system with the capacity to provide improved mental health care for children, there must be solid connections between collection of health data, development of clinically useful bedside tools to support quality of care, and communication between child health care providers. In the last decade, EHRs have evolved from tools predominantly used for documentation to interactive clinical decision-support systems that change care processes. A simple example is a clinician presented with a banner or flag that serves as a reminder a of national quality measure (e.g., a banner with the date a last weight was documented for a child treated with an antipsychotic), prompting adherence to the measure. With increasing use of measurement-based care, a larger number of standardized scales commonly used in psychiatry (e.g., the GAD-7, PHQ-9) and pediatrics (e.g., the M-CHAT) are EHR-integrated [41, 42]. Notably, integration of these measures must be balanced with corresponding workflow infrastructure, such as by administration of measures through patient portals prior to visits or, perhaps, within a collaborative care framework, by another provider prior to referral. This growing link between health data collection, clinical workflows, and communication between providers supports the importance of collaborations in clinical informatics. Here is an opportunity for child psychiatrists to inform the development of clinically useful bedside tools and consider how these tools will generate data to support care in an integrated and scalable framework, particularly within primary care integrated contexts and collaborative care models emphasizing population health-oriented systems of care. Mobilization of health information across organizations, communities, and hospitals remains a barrier, and necessitates that child mental health providers have an awareness of efforts to improve health information exchange to further this vision.

In this issue, Aras [43] discusses the use of objective structured clinical examinations in measuring child psychiatry trainees’ competency in communicating with children and families, highlighting the evolving challenge to assess live clinical performance. In practice, trainees are encouraged to learn the skill of “synchronous documentation,” involving reviewing health records, writing clinical documentation, entering orders, resolving decision support prompts, and billing workflows, all while interfacing with the child and family in-person or through telehealth. As such, the model of “triadic communication” (clinician, patient, family) moves to the “quadratic” (clinician, patient, family, EHR). This is a chance for academic child psychiatrists not only to passively adopt these point-of-care tools traditionally developed from other specialties but also to learn the skills and procedures to proactively develop, refine, and adapt these tools to enhance communication and improve the quality of child mental health care. Physician engagement in the refinement of EHR-based tools has been suggested as one strategy to mitigate burnout, improve EHR proficiency, and increase satisfaction [44].

As clinical informatics accelerates, child psychiatry trainees must also be equipped to interpret the results of risk prediction models derived from health data and embedded in EHRs. Data collected from EHRs offer a promising opportunity for development and validation of risk prediction algorithms using a comprehensive set of potentially predictive variables. In theoretical alignment with the learning health system framework, implementation of risk models in the EHR enhances model usability by making results available to clinicians at point of care and impacting real-time decision-making. On the other hand, EHR-based data also have limitations with regard to data quality, completeness, and generalizability. Appropriate model calibration is contingent on clinical context. Perhaps the most promising application of EHR-based risk prediction is suicide risk assessment. An increasing number of health systems now have implemented suicidal behavior risk prediction models [45], which utilize machine learning and data analytics to process data from millions of individuals and, in turn, deliver a personalized risk prediction of suicidal behavior for an individual child [46]. Here again there is potential for child psychiatrists to participate in the development and implementation of these predictive tools. Input, advocacy, and iterative refinement from clinicians using these tools is imperative to their potential capacity to support quality child mental health care and clinical decision-making.

Education and Training

Education in child psychiatry training will need to provide trainees with the research literacy skills to understand the evidence base informing applications of clinical informatics in child psychiatry. These skills will become increasingly pertinent as trainees are exposed to clinical decision support and EHR-driven risk prediction in everyday practice. It is important that training support an awareness of potential areas of bias, for example, the potential for model miscalibration depending on clinical context, and racial and ethnic differences in the statistical performance of risk prediction models [47]. There is also a growing need for educators to teach trainees about aspects of privacy and confidentiality within the context of EHRs, including patient portals and transparent clinical documentation. Considerations for training and education in clinical informatics during and after child and adolescent psychiatry fellowship are presented in Table 3.

The October 2021 emergency declaration in children's mental health called for strategies to meet challenges in child mental health care through innovation and action [1]. How do psychiatric educators provide this generation of child psychiatrists with the skills to translate their clinical expertise to meaningful improvements in health information technology supporting child mental health care? Strategies to increase exposure to and training in clinical informatics must be tempered with recognition of clinical demands in already extended residency training programs. Most child psychiatry trainees are exposed to EHRs in daily practice and, increasingly, other digital health technologies (e.g., mobile apps, patient portals) that inform and shape clinical training. Several psychiatry residencies have recently developed elective specialized “tracks” in clinical informatics, including the University of North Carolina and the University of California, Los Angeles [39]. These were developed, in part, to meet the rising interest of trainees. However, these mechanisms will likely only be accessed by a subset of trainees with a particular interest in this area.

Perhaps a starting point is to build a balanced awareness of the role of health information technology and informatics in the practice of child psychiatry. This discussion must include an awareness of the limitations and potential for biases and harm. In the spirit of learning health systems, trainees may first be encouraged to identify gaps and areas of need in their institution’s EHR system (e.g., improving documentation of access to firearms). They may also be provided with a conceptual framework for how this health data is stored, presented to the clinician, and acted upon within a decision-support system (e.g., through development of a pediatric-specific clinical workflow for firearm safety counseling). They should also be educated on the potential of excessive EHR demands to promote burnout [48,49,50,51]. These exercises in critical thinking related to EHR tools at point-of-care and leveraging of health data for advancement of child mental health, represent a shift in the curriculum away from solely teaching EHR use as an onboarding activity or administrative skill and fosters a more comprehensive understanding of clinical informatics as an evolving component of a learning health care system to support child mental health.

Given the rapidity with which shifts toward health information technology have occurred, child psychiatry educators may wish to seek training opportunities for themselves through departments of clinical informatics, clinical and translational institutes, and computer science and computational psychiatry fora. These relationships may provide opportunities for bidirectional exchanges of knowledge. As clinical experts, child psychiatrists have much to contribute to ascertaining the clinical usefulness and real-world utility of many health technologies. In turn, child psychiatrists also have much to learn from their colleagues, particularly physician informaticists of other specialties, who have dedicated the last decade to the refinement of health information technology to meet the needs of their patient populations.

The COVID-19 pandemic has spurred the field of child and adolescent psychiatry to accelerate the adoption of health technologies to meet the needs of children and families. This shift in practice has also unearthed a gap between advances in technology and training in clinical child and adolescent psychiatry. There are many exciting opportunities to bridge the gap between the bench of health technology development and the bedside of child mental health care. In turn, seizing these opportunities has the potential to improve access to and the quality of child mental health care across the continuum of mental health promotion, prevention, and treatment. Looking forward, we must also seek opportunities to open pathways for interested trainees to pursue formal clinical informatics fellowship training and to develop a balanced awareness of the roles of clinical informatics when training child psychiatry fellows.
