Impact of Pediatric Intensive Care Unit Admission on Family Financial Status and Productivity: A Pilot Study.

OBJECTIVE: A child's pediatric intensive care unit (PICU) admission may have wide-ranging family implications. We assessed nonmedical out-of-pocket expenses (NMOOPEs) and disruptions in work and normal life for parents with a child admitted to the PICU for at least 2 days with acute, new onset, or exacerbation of a critical condition. DESIGN: We conducted a prospective, single-center study; administered a daily verbal response survey on NMOOPEs; stratified families by annual income (<$50 999, $51-99 000, >$100 000); and calculated daily expenditures (DEs), estimated daily budgets (DBs), and percentage of NMOOPEs (%DE/DB). We used a modified caregiver version of the Work Productivity and Activity Impairment Scale to assess the impact of PICU admission on work-related and normal life activities. SETTING: The PICU in an academic, tertiary medical center in the United States. PATIENTS: Patients admitted to PICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The study included 38 families, with median length of PICU stay of 3 days (range 3-13). The mean total NMOOPE was $127 ± $107 (range $5-$511). Financial impact of DB in the 3 annual income groups ranged from 0% to 136% (median 36%), 5% to 18% (median 10%), and 4% to 39% (median 16%), respectively. Total work absenteeism for cohort was 78 days. High levels of distraction were reported in working families, and normal daily activities were interrupted or suspended. CONCLUSIONS: PICU hospitalization results in a range of direct NMOOPEs of varying burden on families and additional work productivity impact. Further research to understand the array of financial implications on families and additional mitigation strategies are needed.

Pediatric Neurocritical Care: A Short Survey of Current Perceptions and Practices.

BACKGROUND: Although attention to neurologic injuries and illnesses in pediatric critical care is not new, a sub-specialized field of pediatric neurocritical care has only recently been recognized. Pediatric neurocritical care is an emerging area of clinical and investigative focus. Little is known about the prevalence of specialized pediatric neurocritical care services nor about perceptions regarding how it is impacting medical practice. This survey sought to capture perceptions about an emerging area of specialized pediatric neurocritical care among practitioners in intersecting disciplines, including pediatric intensivists, pediatric neurologits and pediatric neurosurgeons. METHODS: A web-based survey was distributed via email to members of relevant professional societies and groups. Survey responses were analyzed using descriptive statistics. Differences in responses between groups of respondents were analyzed using Chi-squared analysis where appropriate. MAIN RESULTS: Specialized clinical PNCC programs were not uncommon among the survey respondents with 20% currently having a PNCC service at their institution. Despite familiarity with this area of sub-specialization among the survey respondents, the survey did not find consensus regarding its value. Overall, 46% of respondents believed that a specialized clinical PNCC service improves the quality of care of critically ill children. Support for PNCC sub-specialization was more common among pediatric neurologists and pediatric neurosurgeons than pediatric intensivists. This survey found support across specialties for creating PNCC training pathways for both pediatric intensivists and pediatric neurologists with an interest in this specialized field. CONCLUSIONS: PNCC programs are not uncommon; however, there is not clear agreement on the optimal role or benefit of this area of practice sub-specialization. A broader dialog should be undertaken regarding the emerging practice of pediatric neurocritical care, the potential benefits and drawbacks of this partitioning of neurology and critical care medicine practice, economic and other practical factors, the organization of clinical support services, and the formalization of training and certification pathways for sub-specialization.

Reliability of circulatory and neurologic examination by telemedicine in a pediatric intensive care unit.

OBJECTIVE: To test the hypothesis that telemedicine can reliably be used for many aspects of circulatory and neurologic examinations of children admitted to a pediatric intensive care unit (PICU). STUDY DESIGN: A prospective, randomized study in a 14-bed PICU in a tertiary care, academic-affiliated institution. Eligible patients were >2 months or <19 years of age, not involved in a concurrent study, had parents/guardian able to sign an informed consent form, were not at end-of-life, and had an attending who not only deemed them medically stable, but also felt that the study would not interrupt their care. Other than the Principal Investigator, 6 pediatric intensivists and 7 pediatric critical care fellows were eligible study providers. Two physician providers were randomly assigned to perform circulatory and neurologic examinations according to the American Heart Association/Pediatric Advanced Life Support guidelines in-person and via telemedicine. Findings were recorded on a standardized data collection form and compared. RESULTS: One hundred ten data collection forms were completed. For many aspects of the circulatory and neurologic examinations, outcomes showed substantial to perfect agreement between the in-person and telemedical care providers (kappa = 0.64-1.00). However, assessments of muscle tone had a kappa = 0.23, with a kappa = 0.37 for skin color. CONCLUSIONS: Telemedicine can reliably identify normal and abnormal findings of many aspects of circulatory and neurologic examinations in PICU patients. This finding opens the door to further studies on the use of telemedicine across other disciplines.

Children's Drawings With Narratives in the Hospital Setting: Insights Into the Patient Experience.

OBJECTIVES: To explore PICU patients' experiences and perceptions through their drawings with explanatory narratives. METHODS: Single-center prospective study in a 14-bed PICU in a tertiary care, academic-affiliated hospital. Pediatric patients age 6 to 17 years admitted to the PICU were approached to participate within 12 hours of transfer out of the PICU. Patients completed a brief study interview to identify the best and worst things about their PICU experience. Patients were asked to draw a picture of their experiences and then explain their drawings to study staff. RESULTS: Forty patients (median age 11 [6-17] years) agreed to participate. The median length of PICU stay was 2 days. The best aspects of the PICU stay included staff (25%), entertainment devices (15%), and food (13%). The worst aspects of the PICU stay that were reported were the intravenous line (25%), alarms (10%), and physical discomfort (10%). The most common elements in drawings were self-depictions (88%), monitors (53%), the intravenous line (50%), registered nurses (35%), and television (33%). Patient narratives related to their drawings provided additional insights regarding patient experiences in the PICU and identified various coping mechanisms used by patients to adapt to their experiences. CONCLUSIONS: Drawing, along with explanation, enables patients admitted to a PICU to disclose additional unique descriptive information about their experiences as patients. Facilitating this mode of communication may increase providers' awareness of positive and negative aspects of a PICU admission and may be used to improve pediatric patients' experiences in the hospital setting.

Telemedicine Versus Face-to-Face Evaluations by Respiratory Therapists of Mechanically Ventilated Neonates and Children: A Pilot Study.

BACKGROUND: Mechanical ventilation is one of the most important therapeutic interventions in neonatal and pediatric ICUs. Telemedicine has been shown to reliably extend pediatric intensivist expertise to facilities where expertise is limited. If reliable, telemedicine may extend the reach of pediatric respiratory therapists (RTs) to facilities where expertise does not exist or free up existing RT resources for important face-to-face activities in facilities where expertise is limited. The aim of this study was to determine how well respiratory assessments for ventilated neonates and children correlated when performed simultaneously by 2 RTs face-to-face and via telemedicine. METHODS: We conducted a pilot study including 40 assessments by 16 RTs on 11 subjects (5 neonatal ICU; 6 pediatric ICU). Anonymously completed intake forms by 2 different RTs concurrently assessing 14 ventilator-derived and patient-based respiratory variables were used to determine correlations. RESULTS: Forty paired assessments were performed. Median telemedicine assessment time was 8 min. The Pearson correlation coefficient (r) was used to determine agreement between continuous data, and the Cohen kappa statistics were used for binary variables. Pressure control, PEEP, breathing frequency, and FIO2 perfectly correlated (r = 1, all P < .001) as did the presence of a CO2 monitor and need for increased ventilatory support (kappa = 1). The Pearson correlation coefficient for VT, minute ventilation, mean airway pressure, and oxygen saturation ranged from 0.84 to 0.97 (all P < .001). kappa = 0.41 (95% CI 0.02-0.80) for patient-triggered breaths, and kappa = 0.57 (95% CI 0.19-0.94) for breathing frequency higher than set frequency. kappa = -0.25 (95% CI -0.46 to -0.04) for need for suctioning. CONCLUSIONS: Telemedicine technology was acceptable to RTs. Telemedicine evaluations highly correlated with face-to-face for 10 of 14 aspects of standard bedside respiratory assessment. Poor correlation was noted for more complex, patient-generated parameters, highlighting the importance of further investigation incorporating a virtual stethoscope.

Effect of endothelial shear stress on the progression of coronary artery disease, vascular remodeling, and in-stent restenosis in humans: in vivo 6-month follow-up study.

BACKGROUND: Native atherosclerosis and in-stent restenosis are focal and evolve independently. The endothelium controls local arterial responses by transduction of shear stress. Characterization of endothelial shear stress (ESS) may allow for prediction of progression of atherosclerosis and in-stent restenosis. METHODS AND RESULTS: By using intracoronary ultrasound, biplane coronary angiography, and measurement of coronary blood flow, we represented the artery in accurate 3D space and determined detailed characteristics of ESS and arterial wall/plaque morphology. Patients who underwent stent implantation and who had another artery with luminal obstruction <50% underwent intravascular profiling initially and after 6-month follow-up. Twelve arteries in 8 patients were studied: 6 native and 6 stented arteries. In native arteries, regions of abnormally low baseline ESS exhibited a significant increase in plaque thickness and enlargement of the outer vessel wall, such that lumen radius remained unchanged (outward remodeling). Regions of physiological ESS showed little change. Regions with increased ESS exhibited outward remodeling with normalization of ESS. In stented arteries, there was an increase in intima-medial thickness, a decrease in lumen radius, and an increase in ESS at all levels of baseline ESS. CONCLUSIONS: The present study represents the first experience in humans relating ESS to subsequent outcomes in native and stented arteries. Regions of low ESS develop progressive atherosclerosis and outward remodeling, areas of physiological ESS remain quiescent, and areas of increased ESS exhibit outward remodeling. ESS may have a limited role in in-stent restenosis. This technology can predict areas of minor plaque likely to exhibit progression of atherosclerosis.

Vascular basis for the treatment of myocardial ischemia study: trial design and baseline characteristics.

BACKGROUND: Increased low-density lipoprotein (LDL) and oxidized LDL cholesterol levels adversely affect endothelial function in patients with stable coronary artery disease (CAD). Statin drugs are efficacious in primary and secondary prevention of clinical CAD events, but they have not been extensively studied as a treatment for ischemia during routine daily activities or during exercise, indicators of high-risk in patients with stable CAD. The purpose of the Vascular Basis for the Treatment of Myocardial Ischemia study is to determine whether aggressive lowering of LDL cholesterol level with atorvastatin, with or without supplemental antioxidant vitamins C and E, can improve endothelial function and ischemia during ambulatory electrocardiogram (AECG) monitoring and exercise treadmill testing (ETT). METHODS: Patients are eligible when they have ischemia during an ETT and AECG monitoring and when their fasting total cholesterol level is < or =250 mg/dL. Eligible patients are randomized to receive 1 of 3 treatments: intensive atorvastatin to reduce LDL cholesterol level to < or =80 mg/dL, intensive atorvastatin to reduce LDL cholesterol level to < or =80 mg/dL plus antioxidant vitamins C and E, and control of diet and low-dose lovastatin, when needed, to reduce LDL cholesterol level < or = to 130 mg/dL. Patients undergo endothelial function testing, 48-hour AECG monitoring, and ETT at randomization and at 6 and 12 months. RESULTS: A total of 300 patients have been randomized: 101 to receive atorvastatin alone, 103 to receive atorvastatin plus antioxidant vitamins, and 96 to receive placebo. Baseline characteristics are similar across treatment groups. CONCLUSIONS: The Vascular Basis study will provide important insight on the effects of aggressive management of dyslipidemia with statin drugs and antioxidant vitamins in patients with stable but high-risk CAD.

Reproducibility of coronary lumen, plaque, and vessel wall reconstruction and of endothelial shear stress measurements in vivo in humans.

The purpose of this study was to assess the reproducibility of an in vivo methodology to reconstruct the lumen, plaque, and external elastic membrane (EEM) of coronary arteries and estimate endothelial shear stress (ESS). Ten coronary arteries without significant stenoses (five native and five stented arteries) were investigated. The 3D lumen and EEM boundaries of each coronary artery were determined by fusing end-diastolic intravascular ultrasound images with biplane coronary angiograms. Coronary flow was measured. Computational fluid dynamics was used to calculate local ESS. Complete data acquisition was then repeated. Analysis was performed on each data set in a blinded manner. The intertest correlation coefficients for all arteries for the two measurements of lumen radius, EEM radius, plaque thickness, and ESS were r = 0.96, 0.96, 0.94, 0.91, respectively (all P values < 0.0001). The 3D anatomy and ESS of human coronary arteries can be reproducibly estimated in vivo. This methodology provides a tool to examine the effect of ESS on atherogenesis, remodeling, and restenosis; the contribution of arterial remodeling and plaque growth to changes in the lumen; and the impact of new therapies.
