Improving health care transition and longitudinal care for adolescents and young adults with hydrocephalus: report from the Hydrocephalus Association Transition Summit

Research priorities for improving cognitive and neuropsychological outcomes in hydrocephalus

Hydrocephalus is a neurological disorder that impacts approximately 85 per 100,000 individuals worldwide and is associated with motor and cognitive impairments. While many advances in surgical interventions have helped substantially improve the survival rates and quality of life of those affected, there continues to be significant gaps in our understanding of the etiology of this heterogeneous condition as well as its specific neuropsychological and functional challenges across different phases of life. To address these limitations, the Hydrocephalus Association and Rudi Schulte Research Institute organized a workshop titled, "Improving Cognitive and Psychological Outcomes in Hydrocephalus", composed of top academics in the fields of hydrocephalus, cognition, and neuropsychology, as well as individuals with hydrocephalus or their caregivers. The purpose was to review the available evidence and propose pertinent areas of further research to improve the cognitive functioning, functional status, and quality of life of individuals with hydrocephalus. These topics included cognitive and neuropsychological assessments and daily-life function of children and adults living with hydrocephalus, biomarkers of cognitive function, animal modeling of hydrocephalus, and the longitudinal impact of hydrocephalus treatment. The following paper outlines four primary areas that warrant research: (1) neuropsychological phenotypes, (2) treatment-focused research considerations, (3) translational pre-clinical tools, and (4) establishing pathways for longitudinal care. Through the efforts of this group, the goal of this manuscript is to inspire and direct scientific and clinical inquiry towards these noted research priorities to further improve the lives of individuals with hydrocephalus and their families.

Topical review: The role of psychologists in healthcare transition

Objective

Adolescents and young adults (AYAs) with chronic medical conditions often face significant challenges while transitioning from pediatric to adult healthcare (healthcare transition, HCT). Although some guidelines exist on how to facilitate this process, the specific role of psychologists in promoting successful HCT is not clearly defined. In this topical review, we propose a conceptual framework integrating the role of psychology within HCT. We also provide an agenda for behavioral health researchers investigating ways to improve transition services/care for emerging adults.

Method

We first review existing standards of care and HCT guidelines. Using existing literature and the Got Transition model as a theoretical foundation, we developed a conceptual framework to outline the specific roles and recommendations for integrating psychologists in the HCT process, including recommendations for future research in this area.

Results

Limited research has systematically examined the efficacy and effectiveness of HCT services, which vary widely across institutions and populations. Further, existing HCT guidelines/recommendations largely exclude the role of psychologists during this process. There are many opportunities for psychologists to provide essential services as part of an interdisciplinary HCT team and to better understand how to improve these models of care.

Conclusions

Psychologists offer a unique and specialized element essential to fostering effective HCT. These professionals can take a more active role in promoting successful HCT from both clinical and research perspectives.

Paediatric hydrocephalus

Hydrocephalus is classically considered as a failure of cerebrospinal fluid (CSF) homeostasis that results in the active expansion of the cerebral ventricles. Infants with hydrocephalus can present with progressive increases in head circumference whereas older children often present with signs and symptoms of elevated intracranial pressure. Congenital hydrocephalus is present at or near birth and some cases have been linked to gene mutations that disrupt brain morphogenesis and alter the biomechanics of the CSF-brain interface. Acquired hydrocephalus can develop at any time after birth, is often caused by central nervous system infection or haemorrhage and has been associated with blockage of CSF pathways and inflammation-dependent dysregulation of CSF secretion and clearance. Treatments for hydrocephalus mainly include surgical CSF shunting or endoscopic third ventriculostomy with or without choroid plexus cauterization. In utero treatment of fetal hydrocephalus is possible via surgical closure of associated neural tube defects. Long-term outcomes for children with hydrocephalus vary widely and depend on intrinsic (genetic) and extrinsic factors. Advances in genomics, brain imaging and other technologies are beginning to refine the definition of hydrocephalus, increase precision of prognostication and identify nonsurgical treatment strategies.

Establishing ranked priorities for future hydrocephalus research

OBJECTIVE

The aim of this initiative was to develop a ranked list of hydrocephalus research priorities as determined by the hydrocephalus patient community in conjunction with the healthcare and scientific community.

METHODS

Using the validated methodology published by the James Lind Alliance (JLA), the Hydrocephalus Association (HA) administered two surveys and hosted a final prioritization workshop. Survey One solicited open-ended responses from the community. From these responses, a long list of priority statements was developed. This list was then consolidated into a short list of research priority statements, which, after a nonsystematic literature review, were verified as being research uncertainties. Survey Two asked the community members to select their top 10 priorities from the short list. The final prioritization leading to a final ranked top 20 list of hydrocephalus research priorities took place at a virtual workshop led by a team of trained facilitators, by means of an iterative process of consensus building.

RESULTS

From Survey One, 3703 responses from 890 respondents were collected, leading to a long list of 146 priority statements. The consolidated short list contained 49 research priority statements, all of which were verified as uncertainties in hydrocephalus research. From an analysis of Survey Two responses, the top 21 research priority statements were determined. A consensus on these statements was reached at the virtual workshop, leading to a final ranked top 20 list of hydrocephalus research priorities, within which needs were apparent in several areas: development of noninvasive and/or one-time therapies, reduction of the burden of current treatments, improvement of the screening and diagnosis of hydrocephalus, improved quality of life, and improved access to care.

CONCLUSIONS

By gathering extensive input from the hydrocephalus community and using an iterative process of consensus building, a ranked list of the top 20 hydrocephalus research priorities was developed. The HA will use this ranked list to guide future research programs and encourages the healthcare and scientific community to do the same.

A qualitative study of transitioning patients with hydrocephalus from pediatric to adult care: fear of uncertainty, communication gaps, independence, and loss of relationships

OBJECTIVE

Hydrocephalus is one of the most common condition treated by pediatric neurosurgeons. Many neurosurgeons are unable to continue to care for patients after they become adults. Although significant gaps in care are believed to exist for youth transitioning from pediatric to adult care, very little is known about how patients and their caregivers feel about the process. This qualitative study sought to examine the perceptions of adolescents, young adults, and their caregivers regarding transitioning from pediatric to adult care at a single Canadian center.

METHODS

The authors explored the perceptions of patients with treated hydrocephalus and their caregivers using semistructured interviews and qualitative research methodologies. A convenience sample was recruited, composed of adolescent patients and their caregivers at the neurosurgery clinic of BC Children's Hospital, and patients and caregivers recently transitioned to adult care from the clinic. Interviews were transcribed verbatim and coded, with common themes identified.

RESULTS

Four overarching themes relating to the process of transitioning from pediatric to adult hydrocephalus care for patients and their caregivers were identified from the data: 1) achieving independence, 2) communication gaps, 3) loss of significant relationships and environment, and 4) fear of uncertainty.

CONCLUSIONS

Overall, patients with hydrocephalus and their families are dissatisfied with the process of transitioning. This study identified common themes and concerns among this cohort that may form the basis of an improved transition model for youth with hydrocephalus as they become adults.

Pediatric to Adult Hydrocephalus: A Smooth Transition

Introduction

Pediatric patients treated for hydrocephalus, regardless of etiology, require continuous access to care to address the long-term sequelae from the disease progression itself and from the interventions undertaken. The challenge for all pediatric neurosurgeons is providing comprehensive and coordinated care for these patients in order to achieve a smooth and seamless transition into adult health care.

Methods

A review of the literature was conducted regarding the overall concept of pediatric patients with chronic conditions transitioning to adult care. We also specifically reviewed the pediatric hydrocephalus literature to investigate the barriers of transition, models of success, and specific elements required in a transition policy.

Results

The review identified several barriers that hamper smooth and successful transition from pediatric to adult care within the hydrocephalus population. These included patient-related, cultural/society-related, healthcare provider-related, and healthcare system-related barriers. Six elements for successful transitions were noted: transition policy, tracking and monitoring, transition readiness, transition planning, transfer of care, and transition completion stemming from the Got Transition center.

Conclusions

A successful patient transition from pediatric neurosurgical care to adult neurosurgical care is very center-specific and depends on the available resources within that center's hospital, health system, and geo-economic environment. Six recommendations are made for transition policy implementation in resource-poor environments, including beginning the process early, preferably at age 14 years.

Continue the Conversation: A Complex Care Pediatrician's Perspective on Improving Healthcare Transitions for Pediatric Neurology Patients

Inadequate preparation for transition to adult-oriented systems of care leads to gaps in treatment and can result in poor health outcomes for youth with special healthcare needs. Coordination between primary care and specialists must occur at multiple levels of organizations to improve transition for youth with neurological disorders. This review focuses on the transition process from the pediatrician's perspective, highlights common obstacles, addresses the unique needs of youth with intellectual disabilities, reviews relevant guidelines, and discusses emerging transition strategies. Key recommendations include defining the roles of the different healthcare providers and using multidisciplinary collaboration to overcome limited resources.

Transesophageal Echocardiography-Guided Ventriculoatrial Shunt Insertion

BACKGROUND

Determining an optimal location within the right atrium (RA) for placement of the distal ventriculoatrial (VA) shunt catheter offer several operative challenges that place patients at risk for perioperative complications and downstream VA shunt failure. Utilizing transesophageal echocardiography (TEE) guidance to place distal VA shunt catheters may help to circumvent these risks.

OBJECTIVE

To review our current practice of VA shunt insertion using TEE guidance.

METHODS

A retrospective review of all consecutive patients who underwent VA shunt procedures between December 19, 2016 and January 22, 2019, during which time intraoperative TEE was used for shunt placement was performed. Data on the time required for shunt placement and total procedure time, baseline echocardiography findings, and short- and long-term complications of shunt placement were assessed.

RESULTS

A total of 33 patients underwent VA shunt procedures, with a median follow-up time of 250 (88-412) d. The only immediate complication related to shunt placement or TEE use was transient ectopy in 1 patient. The mean time for atrial catheter insertion was 12.6 ± 4.8 min. Right-heart catheters were inserted between the RA-superior vena cava junction and 22 mm within the RA in all but 3 procedures. A total of 7/33 patients (21%) underwent shunt revision. Indications for revisions included distal clots, proximal obstruction, positive blood culture, and shunt valve revision. No other complications of VA shunt insertion were reported.

CONCLUSION

VA shunt insertion using TEE allows for precise distal catheter placement. Early patient experience confirms this technique has a low complication rate.

Health care transition in pediatric neurosurgery: a consensus statement from the American Society of Pediatric Neurosurgeons

OBJECTIVE

The number of children with complex medical conditions surviving to adulthood is increasing. A planned transition to adult care systems is essential to the health maintenance of these patients. Guidance has been established for the general health care transition (HCT) from adolescence to adulthood. No formal assessment of the performance of pediatric neurosurgeons in HCT has been previously performed. No "best practice" for this process in pediatric neurosurgery currently exists. The authors pursued two goals in this paper: 1) define the current state of HCT in pediatric neurosurgery through a survey of the membership of the American Society of Pediatric Neurosurgeons (ASPN) on current methods of HCT, and 2) develop leadership-endorsed best-practice guidelines for HCT from pediatric to adult neurosurgical health care.

METHODS

Completion of the Current Assessment of Health Care Transition Activities survey was requested of 178 North American pediatric neurosurgeons by using a web-based questionnaire to capture HCT practices of the ASPN membership. The authors concurrently conducted a PubMed/MEDLINE-based literature review of HCT for young adults with special health care needs, surgical conditions, and/or neurological conditions for the period from 1990 to 2018. Selected articles were assembled and reviewed by subject matter experts and members of the ASPN Quality, Safety, and Advocacy Committee. Best-practice recommendations were developed and subjected to peer review by external expert groups.

RESULTS

Seventy-six responses to the survey (43%) were received, and 62 respondents (82%) answered all 12 questions. Scores of 1 (lowest possible score) were recorded by nearly 60% of respondents on transition policy, by almost 70% on transition tracking, by 85% on transition readiness, by at least 40% on transition planning as well as transfer of care, and by 53% on transition completion. Average responses on all core elements were < 2 on the established 4-point scale. Seven best-practice recommendations were developed and endorsed by the ASPN leadership.

CONCLUSIONS

The majority of pediatric neurosurgeons have transition practices that are poor, do not meet the needs of patients and families, and should be improved. A structured approach to transition, local engagement with adult neurosurgical providers, and national partnerships between pediatric and adult neurosurgery organizations are suggested to address current gaps in HCT for patients served by pediatric neurosurgeons.
