Development of a Randomized Trial Comparing ICP-Monitor-Based Management of Severe Pediatric Traumatic Brain Injury to Management Based on Imaging and Clinical Examination Without ICP Monitoring-Research Algorithms.

BACKGROUND AND OBJECTIVES: The efficacy of our current approach to incorporating intracranial pressure (ICP) data into pediatric severe traumatic brain injury (sTBI) management is incompletely understood, lacking data from multicenter, prospective, randomized studies. The National Institutes of Health-supported Benchmark Evidence from Latin America-Treatment of Raised Intracranial Pressure-Pediatrics trial will compare outcomes from pediatric sTBI of a management protocol based on ICP monitoring vs 1 based on imaging and clinical examination without monitoring. Because no applicable comprehensive management algorithms for either cohort are available, it was necessary to develop them. METHODS: A consensus conference involving the 21 intensivists and neurosurgeons from the 8 trial sites used Delphi-based methodology to formulate management algorithms for both study cohorts. We included recommendations from the latest Brain Trauma Foundation pediatric sTBI guidelines and the consensus-based adult algorithms (Seattle International Brain Injury Consensus Conference/Consensus Revised Imaging and Clinical Examination) wherever relevant. We used a consensus threshold of 80%. RESULTS: We developed comprehensive management algorithms for monitored and nonmonitored cohort children with sTBI. We defined suspected intracranial hypertension for the nonmonitored group, set minimum number and timing of computed tomography scans, specified minimal age-adjusted mean arterial pressure and cerebral perfusion pressure targets, defined clinical neuroworsening, described minimal requisites for intensive care unit management, produced tiered management algorithms for both groups, and listed treatments not routinely used. CONCLUSION: We will study these protocols in the Benchmark Evidence from Latin America-Treatment of Raised Intracranial Pressure-Pediatrics trial in low- and middle-income countries. Second, we present them here for consideration as prototype pediatric sTBI management algorithms in the absence of published alternatives, acknowledging their limited evidentiary status. Therefore, herein, we describe our study design only, not recommended treatment protocols.

Development of a Randomized Trial Comparing ICP-Monitor-Based Management of Severe Pediatric Traumatic Brain Injury to Management Based on Imaging and Clinical Examination Without ICP Monitoring-Study Protocol.

BACKGROUND AND OBJECTIVES: Traumatic brain injury (TBI) is a major global public health problem. It is a leading cause of death and disability in children and adolescents worldwide. Although increased intracranial pressure (ICP) is common and associated with death and poor outcome after pediatric TBI, the efficacy of current ICP-based management remains controversial. We intend to provide Class I evidence testing the efficacy of a protocol based on current ICP monitor-based management vs care based on imaging and clinical examination without ICP monitoring in pediatric severe TBI. METHODS: A phase III, multicenter, parallel-group, randomized superiority trial performed in intensive care units in Central and South America to determine the impact on 6-month outcome of children aged 1-12 years with severe TBI (age-appropriate Glasgow Coma Scale score ≤8) randomized to ICP-based or non-ICP-based management. EXPECTED OUTCOMES: Primary outcome is 6-month Pediatric Quality of Life. Secondary outcomes are 3-month Pediatric Quality of Life, mortality, 3-month and 6-month Pediatric extended Glasgow Outcome Score, intensive care unit length of stay, and number of interventions focused on treating measured or suspected intracranial hypertension. DISCUSSION: This is not a study of the value of knowing the ICP in sTBI. This research question is protocol-based. We are investigating the added value of protocolized ICP management to treatment based on imaging and clinical examination in the global population of severe pediatric TBI. Demonstrating efficacy should standardize ICP monitoring in severe pediatric TBI. Alternate results should prompt reassessment of how and in which patients ICP data should be applied in neurotrauma care.

Assessing the association between pesticide exposure and cognitive development in rural Costa Rican children living in organic and conventional coffee farms.

We examined the association between pesticide exposure and cognitive development among rural Costa Rican children in a cross-sectional study. Study participants aged 4-10 years included 17 children whose parents worked in La Amistad organic coffee plantation and 18 Las Mellizas children whose parents worked in their own small conventional coffee farms. Two spot-urine samples were collected from each participant and analyzed for organophosphorus and pyrethroids pesticide metabolites. We administered the computerized Behavioral Assessment and Research System (BARS), a figure-drawing task, and a long-term memory test to evaluate study participant's cognitive development. Although urinary pesticide metabolite levels did not vary considerably between these two groups of children, we found that Las Mellizas children performed better in BARS and the figure drawing tests than did La Amistad. The results from the linear mixed-effects models suggested that family socioeconomic status (SES) might be a significant contributor to the variation of the outcomes of the neurobehavioral tests. The effect of pesticide exposure, however, as measured in a snapshot fashion, did not play a significant role to the performance of the cognitive development evaluation. Regardless of the study limitations, needed effort should be devoted to the improvement of the SES on the La Amistad families so that their children's cognitive development would not be compromised further. Additionally, future studies should focus on addressing the limitations imposed on the snapshot assessment of pesticide exposure and on conducting cognitive development evaluation so the link between childhood pesticide exposure and their cognitive development can be thoroughly investigated.

Telepsychiatry improves paediatric behavioural health care in rural communities.

In the US, children with special health care needs are underserved by both the medical and educational systems. This problem is especially serious in rural states. Telemedicine is a technique that can reduce these gaps in service and help connect the two systems. The technology required has become cheaper and more accessible. Progress on reimbursement for such services has also been made. For some years, we have provided telepsychiatry for children in Washington State using videoconferencing. Interviews with families and service providers were conducted in Washington and Missouri. Some parents reported that their child actually preferred telepsychiatry to conventional consultation. The telepsychiatry service model was built on the existing system of outreach clinics, thus involving specialists who were familiar with the community and who were known and trusted by the community. Before starting, we ensured that all relevant service delivery agencies and providers were comfortable about using videoconferencing as a method of service delivery. In the 18-month period ending in March 2003, three providers in Seattle saw 159 patients by telepsychiatry and 210 patients face-to-face at the hospital clinic. The main barrier to further growth of the telepsychiatry service is the absence of reimbursement for telepsychiatry.

Telepsychiatry with children and adolescents: are patients comparable to those evaluated in usual outpatient care?

Several studies have described successful applications of telepsychiatry with children and adolescents. However, there has been little examination of the populations served by telepsychiatry and the ability to evaluate youth accurately through this medium. In this article, we examined whether telepsychiatry patients are representative of those in usual outpatient care. Participants included 369 patients 3-19 years old evaluated at two clinics. A new telepsychiatry clinic (TPC) developed to provide services to under-served communities, and a child and adolescent psychiatric outpatient clinic (CAPOC) that served youth from predominantly metropolitan areas were included in the study. The telepsychiatry sites were linked using ISDN lines at 384 KB/sec. We examined these two samples regarding demographics, payor status, and diagnostic profiles. Results indicated that youth evaluated through the TPC were broadly comparable to youth evaluated in the CAPOC. Therefore, telepsychiatry appears to serve youth that are representative of those seeking psychiatric care, and it is not restricted to youth with no medical insurance or with selected diagnoses. The similarity of diagnoses further suggests that telepsychiatry provides adequate technical resolution and doctor-patient rapport to detect psychopathology of youths. These findings suggest the need for further systematic investigation of telepsychiatry as a tool for providing psychiatric care to young people.

Behavioral health: setting the rural health research agenda.

This article seeks to identify current research priorities in the area of rural behavioral health. The method for accomplishing this task begins by identifying several domains where policy has a potential to effect improvements in access or quality but has been hampered by lack of empirical knowledge. In each domain a synthesis of current research summarizes what is known and draws attention to knowledge gaps. Research questions in each domain are proposed. The policy domains are theoretically based, using a conceptual model of access to health care, with a focus on illness level (prevalence), enabling factors (the delivery system, organization and financing, the promise of telemedicine), and predisposing factors (special populations, beliefs, values, stigma).
