Guideline Adherence and Hospital Costs in Pediatric Severe Traumatic Brain Injury

Child Opportunity Index and Hospital Utilization in Children With Traumatic Brain Injury Admitted to the PICU

The need to understand how Community-based disparities impact morbidity and mortality in pediatric critical illness, such as traumatic brain injury. Test the hypothesis that ZIP code-based disparities in hospital utilization, including length of stay (LOS) and hospital costs, exist in a cohort of children with traumatic brain injury (TBI) admitted to a PICU using the Child Opportunity Index (COI).

DESIGN

Multicenter retrospective cohort study.

SETTING

Pediatric Health Information System (PHIS) database.

PATIENTS

Children 0-18 years old admitted to a PHIS hospital with a diagnosis of TBI from January 2016 to December 2020 requiring PICU care. To identify the most severely injured children, a study-specific definition of "Complicated TBI" was created based on radiology, pharmacy, and procedure codes.

INTERVENTIONS

None.

Main Outcomes and Measures

Using nationally normed ZIP code-level COI data, patients were categorized into COI quintiles. A low COI ZIP code has low childhood opportunity based on weighted indicators within educational, health and environmental, and social and economic domains. Population-averaged generalized estimating equation (GEE) models, adjusted for patient and clinical characteristics examined the association between COI and study outcomes, including hospital LOS and accrued hospital costs. The median age of this cohort of 8,055 children was 58 months (interquartile range [IQR], 8-145 mo). There were differences in patient demographics and rates of Complicated TBI between COI levels. The median hospital LOS was 3.0 days (IQR, 2.0-6.0 d) and in population-averaged GEE models, children living in very low COI ZIP codes were expected to have a hospital LOS 10.2% (95% CI, 4.1-16.8%; p = 0.0142) longer than children living in very high COI ZIP codes. For the 11% of children with a Complicated TBI, the relationship between COI and LOS was lost in multivariable models. COI level was not predictive of accrued hospital costs in this study.

CONCLUSIONS

Children with TBI requiring PICU care living in low-opportunity ZIP codes have higher injury severity and longer hospital LOS compared with children living in higher-opportunity ZIP codes. Additional studies are needed to understand why these differences exist.

Quality and patient safety research in pediatric neurosurgery: a review

BACKGROUND

In 2001, the National Academy of Medicine, formerly known as the Institute of Medicine (IOM), published their seminal work, Crossing the Quality Chasm: A New Health System for the 21st Century. In this work, the authors called for improved safety, effectiveness, patient-centeredness, timeliness, efficiency, and equity in the United States' healthcare system. Two decades after the publication of this work, healthcare costs continue to rise, but outcomes lag other nations. The objective of this narrative review is to describe research efforts in pediatric neurosurgery with respect to the six quality aims proposed by the IOM, and highlight additional research opportunities.

METHODS

PubMed, Google Scholar, and EBSCOhost were queried to identify studies in pediatric neurosurgery that have addressed the aims proposed by the IOM. Studies were summarized and synthesized to develop a set of research opportunities to advance quality of care.

RESULTS

Twenty-three studies were reviewed which focused on the six quality aims proposed by the IOM. Out of these studies, five research opportunities emerged: (1) To examine performance of tools of care, (2) To understand processes surrounding care delivery, (3) To conduct cost-effectiveness analyses for a broader range of neurosurgical conditions, (4) To identify barriers driving healthcare disparities, and (5) To understand patients' and caregivers' experiences receiving care, and subsequently develop tools and programs to address their needs and preferences.

CONCLUSION

There is a growing body of literature examining quality in pediatric neurosurgical care across all aims proposed by the IOM. However, there remains important gaps in the literature that, if addressed, will advance the quality of pediatric neurosurgical care delivery.

The Pediatric Guideline Adherence and Outcomes (PEGASUS Argentina) program in severe traumatic brain injury: study protocol adaptations during the COVID-19 pandemic for a multisite implementation-effectiveness cluster randomized controlled trial

BACKGROUND

The aim of this protocol is to describe the study protocol changes made and subsequently implemented to the Pediatric Guideline Adherence and Outcomes (PEGASUS) Argentina randomized controlled trial (RCT) for care of children with severe traumatic brain injuries (TBI) imposed by the COVID-19 pandemic. The PEGASUS study group met in spring 2020 to evaluate available literature review guidance and the study design change or pausing options due to the potential interruption of research.

METHODS

As a parallel cluster RCT, pediatric patients with severe TBIs are admitted to 8 control (usual care) and 8 intervention (PEGASUS program) hospitals in Argentina, Chile, and Paraguay. PEGASUS is an intervention that aims to increase guideline adherence and best practice care for improving patient outcomes using multi-level implementation science-based approaches. Strengths and weaknesses of proposed options were assessed and resulted in a decision to revert from a stepped wedge to a parallel cluster RCT but to not delay planned implementation.

DISCUSSION

The parallel cluster design was considered more robust and flexible to secular interruptions and acceptable and feasible to the local study sites in this situation. Due to the early stage of the study, the team had flexibility to redesign and implement a design more compatible with the conditions of the research landscape in 2020 while balancing analytical methods and power, logistical and implementation feasibility, and acceptability. As of fall 2022, the PEGASUS RCT has been active for nearly 2 years of implementation and data collection, scheduled to be completed in in fall 2023. The experience of navigating research during this period will influence decisions about future research design, strategies, and contingencies.

Provider perceptions of severe pediatric traumatic brain injury care priorities across hospitals in South America before and during the COVID-19 pandemic

Background

To understand provider perceptions of the COVID-19 pandemic on priorities of severe pediatric traumatic brain injury (TBI) care across hospitals in South America.

Methods

Site principal investigators (PIs) from 17 hospitals in South America enrolled in the PEGASUS-Argentina randomized controlled trial completed questionnaires regarding order of tasks performed in the care of a typical pediatric patient with severe TBI before (2019) and during (2021) the COVID-19 pandemic. Acute care processes were examined by quintiles to identify early, mid, and late actions and were categorized and compared. Associations of hospital volume and subspecialty resource availability with prioritization of key process actions were examined.

Finding

Site PIs from 15 and 16 hospitals completed the surveys in 2019 and 2021, respectively, including 14 who completed both. Action category order was stable between 2019 and 2021 and were ranked in priorities as: initial encounter, primary survey, interventions and invasive monitors, diagnostics, medications, staff communication, then disposition (in 2019) or nutrition (in 2021). There was variation in specific action order between hospitals at both timepoints, with only a few initial encounter and disposition actions limited to a single quintile. There was no reported association between hospital volume or subspecialty resource availability with prioritization of key process actions.

Interpretation

Despite novel healthcare challenges presented by the COVID-19 pandemic, providers in South America perceived maintaining standard severe pediatric TBI care consistent with BTF guidelines. There was large variability in specific action order between individual hospitals reported.

The Status of Quality Improvement Programs for Pediatric Traumatic Brain Injury Care in Argentina

INTRODUCTION

Trauma quality improvement (QI) programs improve care and outcomes for injured patients. Information about QI programs for pediatric traumatic brain injury (TBI) is sparse in Latin America.

METHODS

We gathered data on the status of QI programs and activities that encompass pediatric TBI at 15 Argentine hospitals. Data were gathered during 2019 and included hospital characteristics, QI practices, presence of a queryable registry, and use of protocols for TBI care. Level of QI activities was compared between hospital types using Fisher's exact test.

RESULTS

Most hospitals had guidelines for pediatric TBI care, including management and/or prevention of intracranial pressure (100%) and central-line-associated infections (87%). Morbidity and mortality meetings or other types of case discussions in which quality of pediatric TBI care was discussed were held by all hospitals, with most (53%) having weekly-monthly meetings, but 27% having rare or annual meetings. Sixty percent of hospitals had adequate data for case reviews (fewer than 25% of cases with essential information missing). Fifty-three percent documented discussions that occurred at these meetings and 53% utilized computerized trauma registries. Larger hospitals (> 200 beds) more frequently had adequate data (88%) for case reviews than smaller hospitals (29%, P = 0.046). Hospital size did not affect other QI activities.

CONCLUSIONS

Most hospitals had guidelines for pediatric TBI care. Adequacy of care was discussed at reasonably frequent case conferences. Opportunities for improvement include increasing documentation of case reviews and improving adequacy of data for case reviews, especially at smaller hospitals. Greater use of computerized trauma registries could provide such data.

Clinical and Physiologic Factors Associated With Mode of Death in Pediatric Severe TBI

Aims and Objectives: Severe traumatic brain injury (sTBI) is the leading cause of death in children. Our aim was to determine the mode of death for children who died with sTBI in a Pediatric Critical Care Unit (PCCU) and evaluate factors associated with mortality. Methods: We performed a retrospective cohort study of all severely injured trauma patients (Injury Severity Score ≥ 12) with sTBI (Glasgow Coma Scale [GCS] ≤ 8 and Maximum Abbreviated Injury Scale ≥ 4) admitted to a Canadian PCCU (2000-2016). We analyzed mode of death, clinical factors, interventions, lab values within 24 h of admission (early) and pre-death (48 h prior to death), and reviewed meeting notes in patients who died in the PCCU. Results: Of 195 included patients with sTBI, 55 (28%) died in the PCCU. Of these, 31 (56%) had a physiologic death (neurologic determination of death or cardiac arrest), while 24 (44%) had withdrawal of life-sustaining therapies (WLST). Median (IQR) times to death were 35.2 (11.8, 86.4) hours in the physiologic group and 79.5 (17.6, 231.3) hours in the WLST group (p = 0.08). The physiologic group had higher partial thromboplastin time (PTT) within 24 h of admission (p = 0.04) and lower albumin prior to death (p = 0.04). Conclusions: Almost half of sTBI deaths in the PCCU were by WLST. There was a trend toward a longer time to death in these patients. We found few early and late (pre-death) factors associated with mode of death, namely higher PTT and lower albumin.

One-year costs of intensive care in pediatric patients with traumatic brain injury

OBJECTIVE

Traumatic brain injury (TBI) is a major cause of death and disability in the pediatric population. The authors assessed 1-year costs of intensive care in pediatric TBI patients.

METHODS

In this retrospective multicenter cohort study of four academic ICUs in Finland, the authors used the Finnish Intensive Care Consortium database to identify children aged 0-17 years treated for TBI in ICUs between 2003 and 2013. The authors reviewed all patient health records and head CT scans for admission, treatment, and follow-up data. Patient outcomes included functional outcome (favorable outcome defined as a Glasgow Outcome Scale score of 4-5) and death within 6 months. Costs included those for the index hospitalization, rehabilitation, and social security up to 1 year after injury. To assess costs, the authors calculated the effective cost per favorable outcome (ECPFO).

RESULTS

In total, 293 patients were included, of whom 61% had moderate to severe TBI (Glasgow Coma Scale [GCS] score 3-12) and 40% were ≥ 13 years of age. Of all patients, 82% had a favorable outcome and 9% died within 6 months of injury. The mean cost per patient was €48,719 ($54,557) (95% CI €41,326-€56,112). The index hospitalization accounted for 66%, rehabilitation costs for 27%, and social security costs for 7% of total healthcare costs. The ECPFO was €59,727 ($66,884) (95% CI €52,335-€67,120). A higher ECPFO was observed among patients with clinical and treatment-related variables indicative of parenchymal swelling and high intracranial pressure. Lower ECPFO was observed among patients with higher admission GCS scores and those who had epidural hematomas.

CONCLUSIONS

Greater injury severity increases ECPFO and is associated with higher postdischarge costs in pediatric TBI patients. In this pediatric cohort, over two-thirds of all resources were spent on patients with favorable functional outcome, indicating appropriate resource allocation.

Long-term survival and costs following extracorporeal membrane oxygenation in critically ill children-a population-based cohort study

Background

Extracorporeal membrane oxygenation (ECMO) is used to provide temporary cardiorespiratory support to critically ill children. While short-term outcomes and costs have been evaluated in this population, less is known regarding long-term survival and costs.

Methods

Population-based cohort study from Ontario, Canada (October 1, 2009 to March 31, 2017), of pediatric patients (< 18 years of age) receiving ECMO, identified through the use of an ECMO procedural code. Outcomes were identified through linkage to provincial health databases. Primary outcome was survival, measured to hospital discharge, as well as at 1 year, 2 years, and 5 years following ECMO initiation. We evaluated total patient costs in the first year following ECMO.

Results

We analyzed 342 pediatric patients. Mean age at ECMO initiation was 2.9 years (standard deviation [SD] = 5.0). Median time from hospital admission to ECMO initiation was 5 days (interquartile range [IQR] = 1–13 days). Overall survival to hospital discharge was 56.4%. Survival at 1 year, 2 years, and 5 years was 51.5%, 50.0%, and 42.1%, respectively. Among survivors, 99.5% were discharged home. Median total costs among all patients in the year following hospital admission were $147,957 (IQR $70,571–$300,295). Of these costs, the large proportion were attributable to the inpatient cost from the index admission (median $119,197, IQR $57,839–$250,675).

Conclusions

Children requiring ECMO continue to have a significant in-hospital mortality, but reassuringly, there is little decrease in long-term survival at 1 year. Median costs among all patients were substantial, but largely reflect inpatient hospital costs, rather than post-discharge outpatient costs. This information provides value to providers and health systems, allowing for prognostication of short- and long-term outcomes, as well as long-term healthcare-related expenses for pediatric ECMO survivors.

EVENTS ASSOCIATED WITH THE OCCURRENCE OF INTRACRANIAL HYPERTENSION IN PEDIATRIC PATIENTS WITH SEVERE CRANIOENCEPHALIC TRAUMA AND MONITORING OF INTRACRANIAL PRESSURE

Objective:

To determine the events associated with the occurrence of intracranial hypertension (ICH) in pediatric patients with severe cranioencephalic trauma.

Methods:

This was a prospective cohort study of patients 18 years old and younger with cranioencephalic trauma, scores below nine on the Glasgow Coma Scale, and intracranial pressure monitoring. They were admitted between September, 2005 and March, 2014 into a Pediatric Intensive Care Unit. ICH was defined as an episode of intracranial pressure above 20 mmHg for more than five minutes that needed treatment.

Results:

A total of 198 children and adolescents were included in the study, of which 70.2% were males and there was a median age of nine years old. ICH occurred in 135 (68.2%) patients and maximum intracranial pressure was 36.3 mmHg, with a median of 34 mmHg. A total of 133 (97.8%) patients with ICH received sedation and analgesia for treatment of the condition, 108 (79.4%) received neuromuscular blockers, 7 (5.2%) had cerebrospinal fluid drainage, 105 (77.2%) received mannitol, 96 (70.6%) received hyperventilation, 64 (47.1%) received 3% saline solution, 20 (14.7%) received barbiturates, and 43 (31.9%) underwent a decompressive craniectomy. The events associated with the occurrence of ICH were tomographic findings at the time of admission of diffuse or hemispheric swelling (edema plus engorgement). The odds ratio for ICH in patients with Marshall III (diffuse swelling) tomography was 14 (95%CI 2.8–113; p<0.003), and for those with Marshall IV (hemispherical swelling) was 24.9 (95%CI 2.4–676, p<0.018). Mortality was 22.2%.

Conclusions:

Pediatric patients with severe cranioencephalic trauma and tomographic alterations of Marshall III and IV presented a high chance of developing ICH.

Effects of dexmedetomidine vs sufentanil during percutaneous tracheostomy for traumatic brain injury patients: A prospective randomized controlled trial

BACKGROUND

Percutaneous tracheostomy, almost associated with cough reflex and hemodynamic fluctuations, is a common procedure for traumatic brain injury (TBI) patients, especially those in neurosurgery intensive care units (NICUs). However, there are currently a lack of effective preventive measures to reduce the risk of secondary brain injury. The aim of this study was to compare the effect of dexmedetomidine (DEX) vs sufentanil during percutaneous tracheostomy in TBI patients.

METHODS

The 196 TBI patients who underwent percutaneous tracheostomy were randomized divided into 3 groups: group D1 (n = 62, DEX infusion at 0.5 μg·kg for 10 minutes, then adjusted to 0.2-0.7 μg·kg·hour), group D2 (n = 68, DEX infusion at 1 μg·kg for 10 minutes, then adjusted to 0.2-0.7 μg·kg·hour), and group S (n = 66, sufentanil infusion 0.3 μg·kg for 10 minutes, then adjusted to 0.2-0.4 μg·kg·hour). The bispectral index (BIS) of all patients was maintained at 50 to 70 during surgery. Anesthesia onset time, hemodynamic variables, total cumulative dose of DEX/sufentanil, total doses of rescue propofol and fentanyl, time to first dose of rescue propofol and fentanyl, number of intraoperative patient movements and cough reflexes, adverse events, and surgeon satisfaction score were recorded.

RESULTS

Anesthesia onset time was significantly lower in group D2 than in both other groups (14.35 ± 3.23 vs 12.42 ± 2.12 vs 13.88 ± 3.51 minutes in groups D1, D2, and S, respectively; P < .001). Both heart rate and mean arterial pressure during percutaneous tracheostomy were more stable in group D2. Total doses of rescue propofol and fentanyl were significantly lower in group D2 than in group D1 (P < .001). The time to first dose of rescue propofol and fentanyl were significantly longer in group D2 than in both other groups (P < .001). The number of patient movements and cough reflexes during percutaneous tracheostomy were lower in group D2 than in both other groups (P < .001). The overall incidences of tachycardia and hypertension (which required higher doses of esmolol and urapidil, respectively) were also lower in group D2 than in both other groups (P < .05). Three patients in group S had respiratory depression compared to X in the D1 group and X in the D2 group. The surgeon satisfaction score was significantly higher in group D2 than in both other groups (P < .05).

CONCLUSIONS

During percutaneous tracheostomy, compared with sufentanil, DEX (1 μg·kg for 10 minutes, then adjusted to 0.2-0.7 μg·kg·hour) can provide the desired attenuation of the hemodynamic response without increased adverse events. Consequently, DEX could be used safely and effectively during percutaneous tracheostomy in TBI patients.

In-hospital costs after severe traumatic brain injury: A systematic review and quality assessment

Background

The in-hospital treatment of patients with traumatic brain injury (TBI) is considered to be expensive, especially in patients with severe TBI (s-TBI). To improve future treatment decision-making, resource allocation and research initiatives, this study reviewed the in-hospital costs for patients with s-TBI and the quality of study methodology.

Methods

A systematic search was performed using the following databases: PubMed, MEDLINE, Embase, Web of Science, Cochrane library, CENTRAL, Emcare, PsychINFO, Academic Search Premier and Google Scholar. Articles published before August 2018 reporting in-hospital acute care costs for patients with s-TBI were included. Quality was assessed by using a 19-item checklist based on the CHEERS statement.

Results

Twenty-five out of 2372 articles were included. In-hospital costs per patient were generally high and ranged from $2,130 to $401,808. Variation between study results was primarily caused by methodological heterogeneity and variable patient and treatment characteristics. The quality assessment showed variable study quality with a mean total score of 71% (range 48% - 96%). Especially items concerning cost data scored poorly (49%) because data source, cost calculation methodology and outcome reporting were regularly unmentioned or inadequately reported.

Conclusions

Healthcare consumption and in-hospital costs for patients with s-TBI were high and varied widely between studies. Costs were primarily driven by the length of stay and surgical intervention and increased with higher TBI severity. However, drawing firm conclusions on the actual in-hospital costs of patients sustaining s-TBI was complicated due to variation and inadequate quality of the included studies. Future economic evaluations should focus on the long-term cost-effectiveness of treatment strategies and use guideline recommendations and common data elements to improve study quality.

Prediction of discharge destination after traumatic brain injury in children using the head abbreviated injury scale

INTRODUCTION

Traumatic brain injury (TBI) is a major public health problem, particularly in children. Prognostication of injury severity at the time of presentation is difficult. The Abbreviated Injury Scale (AIS) is a commonly used anatomical-based coding system created to classify and describe injury severity after initial presentation, once test results are able to better define the anatomical characteristics of the injury. We hypothesize that the Head AIS can predict discharge destination in children after TBI.

METHODS

The trauma registry database for a Pediatric Level 1 Trauma center was queried for patients age ≤14 years from 2006 to 2015 with a Head AIS>2. All diagnoses with head AIS>2 were retrieved. Since one patient can have multiple diagnoses with an AIS>2, we selected the diagnosis with highest Head AIS associated with each patient. The demographics, length of stay, and the discharge disposition of patients were retrieved. Descriptive statistics were performed and association of Head AIS with the length of stay and discharge disposition was determined using logistic regression.

RESULTS

393 pediatric patients (age≤14 years) with an Head AIS ≥3, (64.0% males, mean age = 6.2 S.D. 4.58) presented over 10 years. Head AIS was strongly associated with mortality; with 0.8%, 1.1% and 42.0% of patients with Head AIS of 3, 4 and 5, respectively, dying - odds ratio for Head AIS 5 over Head AIS 3 = 89 (logistic regression, p-value<0.001). 80.0% of deaths (23 patients) in this cohort occurred within 24-h of presentation. Head AIS was associated with an increase likelihood of discharge to rehabilitation with 1.2%, 7.7% and 47.0% of survivors discharging to rehabilitation for Head AIS of 3, 4 and 5.

CONCLUSION

Head AIS can reliably predict discharge disposition to home, rehab or death. Calculation of Head AIS prior to discharge could lead to accurate prediction of discharge destination.

The Pediatric Guideline Adherence and Outcomes (PEGASUS) programme in severe traumatic brain injury: a single-centre hybrid implementation and effectiveness study

BACKGROUND

As far as we know, there are no tested in-hospital care programmes for paediatric traumatic brain injury. We aimed to assess implementation and effectiveness of the Pediatric Guideline Adherence and Outcomes (PEGASUS) programme in children with severe traumatic brain injury.

METHODS

We did a prospective hybrid implementation and effectiveness study at the Harborview Medical Center (Seattle, WA, USA). We included children (aged <18 years) with traumatic brain injury (trauma mechanism and image findings). We assessed service provision, adherence to three key performance indicators, and discharge outcomes associated with the PEGASUS programme. The three key performance indicators were early initiation of enteral (oral or tube feeds) or parenteral nutrition; avoidance of any unwanted hypocarbia (PaCO₂ <30 mm Hg) without brain herniation; and maintenance of cerebral perfusion pressure (>40 mm Hg) for 72 h after the diagnosis of severe traumatic brain injury. Poisson regression with robust standard errors was used to estimate the association between adhering to key performance indicators and discharge outcomes.

FINDINGS

Between May 1, 2011, and July 1, 2017, 199 children (median age 11·9 years [IQR 3·4-16·1]) participated in the PEGASUS programme, of whom 193 (97%) had severe traumatic brain injury and six (3%) had moderate traumatic brain injury. 105 patients contributed data for all three key performance indicators. Adherence to at least one key performance indicator was achieved by 101 (96%) of 105 participants, and 44 (42%) achieved adherence to all three key performance indicators. Programme participants achieved adherence to the key performance indicators of hypocarbia (76 of 105 [72%]), nutrition (162 of 199 [81%]), and cerebral perfusion pressure (128 of 199 [64%]). Adherence to the nutrition key performance indicator was associated with higher discharge survival (relative risk [RR] 2·70, 95% CI 1·54-4·73) and a more favourable discharge disposition (3·05, 1·52-6·11). Adherence to the cerebral perfusion pressure key performance indicator was also associated with higher discharge survival (RR 1·33, 95% CI 1·12-1·59) and favourable disposition (1·53, 1·19-1·96). Adherence to each additional key performance indicator was associated with higher survival (RR 1·27, 1·12-1·44) and a more favourable discharge disposition (1·46, 1·23-1·72), in a dose-response manner.

INTERPRETATION

The multilevel, hospital-wide, high-fidelity PEGASUS programme might benefit children and adolescents admitted to the emergency department with severe traumatic brain injury. Cerebral perfusion pressure, nutrition, and hypocarbia targets are essential components of the PEGASUS programme and are associated with favourable discharge outcomes.

The cost of a pediatric neurocritical care program for traumatic brain injury: a retrospective cohort study

Background

Inpatient care for children with severe traumatic brain injury (sTBI) is expensive, with inpatient charges averaging over $70,000 per case (Hospital Inpatient, Children Only, National Statistics. Diagnoses– clinical classification software (CCS) principal diagnosis category 85 coma, stupor, and brain damage, and 233 intracranial injury. Diagnoses by Aggregate charges [https://hcupnet.ahrq.gov/#setup]). This ranks sTBI in the top quartile of pediatric conditions with the greatest inpatient costs (Hospital Inpatient, Children Only, National Statistics. Diagnoses– clinical classification software (CCS) principal diagnosis category 85 coma, stupor, and brain damage, and 233 intracranial injury. Diagnoses by Aggregate charges [https://hcupnet.ahrq.gov/#setup]). The Brain Trauma Foundation developed sTBI intensive care guidelines in 2003, with revisions in 2012 (Kochanek, Carney, et. al. PCCM 3:S1-S2, 2012). These guidelines have been widely disseminated, and are associated with improved health outcomes (Pineda, Leonard. et. al. LN 12:45-52, 2013), yet research on the cost of associated hospital care is limited. The objective of this study was to assess the costs of providing hospital care to sTBI patients through a guideline-based Pediatric Neurocritical Care Program (PNCP) implemented at St. Louis Children’s Hospital, a pediatric academic medical center in the Midwest United States.

Methods

This is a retrospective cohort study. We used multi-level regression to estimate pre−/post−implementation effects of the PNCP program on inflation adjusted total cost of in-hospital sTBI care. The study population included 58 pediatric patient discharges in the pre-PNCP implementation group (July 15, 1999 - September 17, 2005), and 59 post-implementation patient discharges (September 18, 2005 - January 15, 2012).

Results

Implementation of the PNCP was associated with a non-significant difference in the cost of care between the pre- and post-implementation periods (e^β = 1.028, p = 0.687).

Conclusions

Implementation of the PNCP to support delivery of guideline-based care for children with sTBI did not change the total per-patient cost of in-hospital care. A key strength of this study was its use of hospital cost data rather than charges. Future research should consider the longitudinal post-hospitalization costs of this approach to sTBI care.

Intensive care treatments associated with favorable discharge outcomes in Argentine children with severe traumatic brain injury: For the South American Guideline Adherence Group

Objective

Little is known about the critical care management of children with traumatic brain injury (TBI) in low middle income countries. We aimed to identify indicators of intensive care unit (ICU) treatments associated with favorable outcomes in Argentine children with severe TBI.

Methods

We conducted a secondary analysis of data from patients previously enrolled in a prospective seven center study of children with severe TBI who were admitted to an ICU in one of the seven study centers. Severe TBI was defined by head AIS ≥ 3, head CT with traumatic lesion, and admission GCS < 9. Seven indicators of best practice TBI care were examined. The primary outcome was discharge Pediatric Cerebral Performance Category Scale [PCPC] and Pediatric Overall Performance category Scale [POPC]. We also examined variation in ICU care and in-patient mortality.

Results

Of the 117 children, 67% were male and 7.5 (4.3) years on average, 92% had isolated TBI. Hypotension (54%) was more common than hypoxia (28%) and clinical or radiographic signs of high intracranial pressure (ICP) were observed in 92%. Yet, ICP monitoring occurred in 60% and hyperosmolar therapy was used in only 36%. Adherence to indicators of best TBI practice ranged from 55.6% to 83.7% across the seven centers and adherence was associated with favorable discharge PCPC (aRR 0.98; 95% CI [0.96, 0.99]), and POPC (aRR 0.98; 95% CI [0.96, 0.99]). Compared to patients whose adherence rates were below 65%, patients whose adherence rates were higher between 75%-100% had better discharge PCPC (aRR 0.28; 95% CI [0.10, 0.83]) and POPC (aRR 0.32; 95% CI [0.15, 0.73]. Two indicators were associated with favorable discharge PCPC: Avoidance of hypoxia (aRR 0.46; 95% CI [0.23, 0.93]), and Nutrition started in 72 hours (aRR 0.45; 95% CI [0.21, 0.99]). Avoiding hypoxia was also associated with favorable discharge POPC (aRR 0.47; 95% CI [0.22, 0.99]).

Conclusion

There is variation in Argentine ICU practice in the care of children with severe TBI. Second insults are common and hyperosmolar therapy use is uncommon. Adherence to best practice TBI care by avoiding hypoxia and providing timely nutrition were associated with significantly favorable discharge outcomes. Implementing strategies that prevent hypoxia and facilitate early nutrition in the ICUs are urgently needed to improve pediatric TBI outcomes.
