Implementation of a Global Pediatric Trauma Course in an Upper Middle-Income Country: A Pilot Study.

INTRODUCTION: Over 90% of pediatric trauma deaths occur in low- and middle-income countries (LMICs), yet pediatric trauma-focused training remains unstandardized and inaccessible, especially in LMICs. In Brazil, where trauma is the leading cause of death for children over age 1, we piloted the first global adaptation of the Trauma Resuscitation in Kids (TRIK) course and assessed its feasibility. METHODS: A 2-day simulation-based global TRIK course was hosted in Belo Horizonte in October 2022, led by one Brazilian and four Canadian instructors. The enrollment fee was $200 USD, and course registration sold out in 4 d. We administered a knowledge test before and after the course and a postcourse self-evaluation. We recorded each simulation to assess participants' performance, reflected in a team performance score. Groups received numerical scores for these three areas, which were equally weighted to calculate a final performance score. The scores given by the two evaluators were then averaged. As groups performed the specific simulations in varying orders, the simulations were grouped into four time blocks for analysis of performance over time. Statistical analysis utilized a combination of descriptive analysis, Wilcoxon signed-rank tests, Kruskal-Wallis tests, and Wilcoxon rank-sum tests. RESULTS: Twenty-one surgeons (19 pediatric, one trauma, one general) representing four of five regions in Brazil consented to study participation. Women comprised 76% (16/21) of participants. Overall, participants scored higher on the knowledge assessment after the course (68% versus 76%; z = 3.046, P < 0.001). Participants reported improved knowledge for all tested components of trauma management (P < 0.001). The average simulation performance score increased from 66% on day 1% to 73% on day 2, although this increase was not statistically significant. All participants reported they were more confident managing pediatric trauma after the course and would recommend the course to others. CONCLUSIONS: Completion of global TRIK improved surgeons' confidence, knowledge, and clinical decision-making skills in managing pediatric trauma, suggesting a standardized course may improve pediatric trauma care and outcomes in LMICs. We plan to more closely address cost, language, and resource barriers to implementing protocolized trauma training in LMICs with the aim to improve patient outcomes and equity in trauma care globally.

Internal and external validation of an updated ICD-10-CA to AIS-2005 update 2008 algorithm.

BACKGROUND: Administrative data are a powerful tool for population-level trauma research but lack the trauma-specific diagnostic and injury severity codes needed for risk-adjusted comparative analyses. The objective of this study was to validate an algorithm to derive Abbreviated Injury Scale (AIS-2005 update 2008) severity scores from Canadian International Classification of Diseases (ICD-10-CA) diagnostic codes in administrative data. METHODS: This was a retrospective cohort study using data from the 2009 to 2017 Ontario Trauma Registry for the internal validation of the algorithm. This registry includes all patients treated at a trauma center who sustained a moderate or severe injury or were assessed by a trauma team. It contains both ICD-10-CA codes and injury scores assigned by expert abstractors. We used Cohen's kappa (𝜅) coefficient to compare AIS-2005 Update 2008 scores assigned by expert abstractors to those derived using the algorithm and the intraclass correlation coefficient to compare assigned and derived Injury Severity Scores. Sensitivity and specificity for detection of a severe injury (AIS score, ≥ 3) were then calculated. For the external validation of the algorithm, we used administration data to identify adults who either died in an emergency department or were admitted to hospital in Ontario secondary to a traumatic injury (2009-2017). Logistic regression was used to evaluate the discriminative ability and calibration of the algorithm. RESULTS: Of 41,869 patients in the Ontario Trauma Registry, 41,793 (99.8%) had at least one diagnosis matched to the algorithm. Evaluation of AIS scores assigned by expert abstractors and those derived using the algorithm demonstrated a high degree of agreement in identification of patients with at least one severe injury (𝜅 = 0.75; 95% confidence interval [CI], 0.74-0.76). Likewise, algorithm-derived scores had a strong ability to rule in or out injury with AIS ≥ 3 (specificity, 78.5%; 95% CI, 77.7-79.4; sensitivity, 95.1; 95% CI, 94.8-95.3). There was strong correlation between expert abstractor-assigned and crosswalk-derived Injury Severity Score (intraclass correlation coefficient, 0.80; 95% CI, 0.80-0.81). Among the 130,542 patients identified using administrative data, the algorithm retained its discriminative properties. CONCLUSION: Our ICD-10-CA to AIS-2005 update 2008 algorithm produces reliable estimates of injury severity and retains its discriminative properties with administrative data. Our findings suggest that this algorithm can be used for risk adjustment of injury outcomes when using population-based administrative data. LEVEL OF EVIDENCE: Diagnostic Tests/Criteria; Level II.

Injury outcomes across Canadian trauma systems: a historical cohort study.

PURPOSE: Most North American trauma systems have designated trauma centres (TCs) including level I (ultraspecialized high-volume metropolitan centres), level II (specialized medium-volume urban centres), and/or level III (semirural or rural centres). Trauma system configuration varies across provinces and it is unclear how these differences influence patient distributions and outcomes. We aimed to compare patient case mix, case volumes, and risk-adjusted outcomes of adults with major trauma admitted to designated level I, II, and III TCs across Canadian trauma systems. METHODS: In a national historical cohort study, we extracted data from Canadian provincial trauma registries on major trauma patients treated between 2013 and 2018 in all designated level I, II, or III TCs in British Columbia, Alberta, Quebec, and Nova Scotia; level I and II TCs in New Brunswick; and four TCs in Ontario. We used multilevel generalized linear models to compare mortality and intensive care unit (ICU) admission and competitive risk models for hospital and ICU length of stay (LOS). Ontario could not be included in outcome comparisons because there were no population-based data from this province. RESULTS: The study sample comprised 50,959 patients. Patient distributions in level I and II TCs were similar across provinces but we observed significant differences in case mix and volumes for level III TCs. There was low variation in risk-adjusted mortality and LOS across provinces and TCs but interprovincial and intercentre variation in risk-adjusted ICU admission was high. CONCLUSIONS: Our results suggest that differences in the functional role of TCs according to their designation level across provinces leads to significant variations in the distribution of patients, case volumes, resource use, and clinical outcomes. These results highlight opportunities to improve Canadian trauma care and underline the need for standardized population-based injury data to support national quality improvement efforts.

RéSUMé: OBJECTIF: La plupart des systèmes de traumatologie nord-américains disposent de centres de traumatologie (CT) désignés, y compris de niveau I (centres métropolitains ultraspécialisés à volume élevé), de niveau II (centres urbains spécialisés à volume moyen) et/ou de niveau III (centres semi-ruraux ou ruraux). La configuration des systèmes de traumatologie varie d'une province à l'autre et nous ne savons pas comment ces différences influent sur la répartition de la patientèle et sur les issues. Notre objectif était de comparer le mélange de cas des patient·es, le volume de cas et les issues ajustées en fonction du risque des adultes ayant subi un traumatisme majeur admis·es dans des CT désignés de niveaux I, II et III dans l'ensemble des systèmes de traumatologie canadiens. MéTHODE: Dans une étude de cohorte historique nationale, nous avons extrait des données des registres provinciaux canadiens de traumatologie sur les patient·es ayant subi un traumatisme majeur traité·es entre 2013 et 2018 dans tous les CT désignés de niveau I, II ou III en Colombie-Britannique, en Alberta, au Québec et en Nouvelle-Écosse, les CT de niveau I et II au Nouveau-Brunswick, et dans quatre CT en Ontario. Nous avons utilisé des modèles linéaires généralisés à plusieurs niveaux pour comparer la mortalité, les admissions en unité de soins intensifs (USI) et les modèles de risque compétitif pour la durée du séjour à l'hôpital et à l'USI. L'Ontario n'a pas pu être inclus dans les comparaisons des devenirs parce qu'il n'y avait pas de données démographiques pour cette province. RéSULTATS: L'échantillon de l'étude comptait 50 959 patient·es. La répartition des patient·es dans les CT de niveaux I et II était similaire d'une province à l'autre, mais nous avons observé des différences significatives dans le mélange des cas et les volumes pour les CT de niveau III. Il y avait une faible variation de la mortalité ajustée en fonction du risque et des durées de séjour entre les provinces et les CT, mais la variation interprovinciale et intercentre des admissions à l'USI ajustées en fonction du risque était élevée. CONCLUSION: Nos résultats suggèrent que les différences dans le rôle fonctionnel des CT selon leur niveau de désignation d'une province à l'autre entraînent des variations importantes dans la répartition des patient·es, le nombre de cas, l'utilisation des ressources et les issues cliniques. Ces résultats mettent en évidence les possibilités d'amélioration des soins de traumatologie au Canada et soulignent la nécessité de disposer de données normalisées sur les blessures dans la population pour appuyer les efforts nationaux d'amélioration de la qualité.

Between paradigms: Comparing experiences for adolescents treated at pediatric and adult trauma centres.

INTRODUCTION: Injured adolescents may be treated at pediatric trauma centres (PTCs) or adult trauma centres (ATCs). Patient and parent experiences are an integral component of high-quality health care and can influence patient clinical trajectory. Despite this knowledge, there is little research on differences between PTCs and ATCs with respect to patient and caregiver-reported experience. We sought to identify differences in patient and parent-reported experiences between the regional PTC and ATC using a recently developed Patient and Parent-Reported Experience Measure. METHODS: We prospectively enrolled patients (caregivers) aged 15-17 (inclusive), admitted to the local PTC and ATC for injury management (01/01/2020 - 31/05/2021) We provided a survey 8-weeks post-discharge to query acute care and follow-up experience. Patient and parent experiences were compared between the PTC and ATC using descriptive statistics, chi-square tests for categorical and independent t-tests for continuous variables. RESULTS: We identified 90 patients for inclusion (51 PTC, and 39 ATC). From this population, we had 77 surveys (32 patient and 35 caregiver) completed at the PTC, and 41 (20 patient and 21 caregiver) at the ATC. ATC patients tended to be more severely injured. We identified few differences in reported experience on the patient measure but identified lower ratings from caregivers of adolescents treated in ATCs for the domains of information and communication, follow-up care, and overall hospital scores. Patients and parents reported poorer family accommodation at the ATC. CONCLUSION: Patient experiences were similar between centres. However, caregivers report poorer experiences at the ATC in several domains. These differences are multifaceted, and may reflect differing patient volumes, effects of COVID-19, and healthcare paradigms. However, further work should target information and communication improvement in adult paradigms given its impact on other domains of care.

Development of the quality of teen trauma acute care patient and parent-reported experience measure.

OBJECTIVE: Patient-Reported Experience Measures (PREMs) provide valuable patient feedback on quality of care and have been associated with clinical outcomes. We aimed to test the reliability of a modified adult trauma care PREM instrument delivered to adolescents admitted to hospital for traumatic injuries, and their parents. Modifications included addition of questions reflecting teen-focused constructs on education supports, social network maintenance and family accommodation. RESULTS: Forty adolescent patients and 40 parents participated. Test-retest reliability was assessed using Cohen's kappa, weighted kappa, and percent agreement between responses. Directionality of changed responses was noted. Most of the study ran during the COVID-19 pandemic. We established good reliability of questions related to in-hospital and post-discharge communication, clinical and ancillary care and family accommodation. We identified poorer reliability among constructs reflecting experiences that varied from the norm during the pandemic, which included "maintenance of social networks", "education supports", "scheduling clinical follow-ups" and "post-discharge supports". Parents, but not patients, demonstrated more directionality of change of responses by responding with more negative in-hospital and more positive post-discharge experiences over time between the test and retest periods, suggesting risk of recall bias. Situational factors due to the COVID-19 pandemic and potential risks of recall bias may have limited the reliability of some parts of the survey.

The Canadian Consortium for Research in Pediatric Surgery: Roadmap for Creation and Implementation of a National Subspecialty Research Consortium.

Clinical practice should be driven by high-quality research that produces evidence to inform best practices. Generation of such evidence is often challenging, particularly for smaller specialties, such as pediatric surgery, that treat many patients with rare diseases. Multi-institutional collaboration is seen as a major strategy to address these challenges. We have recently created the Canadian Consortium for Research in Pediatric Surgery, a national consortium that includes all major pediatric surgical services across Canada. The mission of the Consortium is to improve pediatric surgical care through high-quality collaborative research. In this article, we describe the rationale and methodology for creation of the Canadian Consortium for Research in Pediatric Surgery, demonstrate its achievements to date, and share a number of foundational concepts that are integral to its success. Our aim is to provide a model for creation of such consortia, ultimately leading to improvements in the quality of clinical research and patient care.

Where to start? Injury prevention priority scores for traumatic injuries in Canada.

BACKGROUND: Given limited resources for injury prevention, it is essential to determine which mechanisms of injury to target to provide the most benefit to the largest proportion of the population. We developed objective, evidence-based injury prevention priority scores (IPPSs) for the Canadian population across 4 prevention perspectives: mortality, injury severity, resource use and societal cost. METHODS: We performed a retrospective cohort study of all injuries in Canada from 2009/10 to 2013/14. Hospital admissions were obtained from the Discharge Abstract Database, and deaths from the Statistics Canada Canadian Vital Statistics Death Database. For each mechanism of injury, we calculated an IPPS as a balanced measure of injury frequency and 1) mortality rate, 2) median 1 - ICISS (Injury Severity Score derived from the International Statistical Classification of Diseases and Related Health Problems, 10th revision, enhanced Canadian version), 3) median cost per hospital stay or 4) median potential years of life lost (PYLL), providing a ranking of mechanisms of injury in priority order. The IPPS by definition has a mean of 50 and a standard deviation of 10. The higher the IPPS, the higher the priority for injury prevention. RESULTS: A total of 694 535 injuries were identified over the study period. The most frequent mechanism of injury was falls (391 068 [56.3%]). The overall mortality rate was 0.09 deaths/injured person, the median 1 - ICISS was 0.017, the median cost was $5217, and the median PYLL was 0. The mechanisms with the 3 highest IPPSs were falls (75), self-harm (67) and drowning (66) for mortality; falls (77), drowning (70) and suffocation (61) for severity; falls (80), suffocation (63) and fire (60) for resource use; and falls (72), assault (62), and firearms and legal interventions (59 in both cases) for societal cost. CONCLUSION: This study produced IPPSs for traumatic injuries in Canada that provide objective and quantifiable methods for identifying mechanisms of injury to target for specific prevention initiatives. Preventing falls would provide the most benefit to the largest proportion of Canadians and should be prioritized in injury-prevention policy.

Pediatric versus adult paradigms for management of adolescent injuries within a regional trauma system.

BACKGROUND: We aimed to examine process and outcome indicators for adolescents with specific injury patterns managed in pediatric versus adult paradigms within the same trauma system. METHODS: Adolescents (15-17 years old) admitted to the region's adult trauma center (ATC) or pediatric trauma center (PTC) with an abdominal injury, femur fracture or traumatic brain injury (TBI) were reviewed retrospectively. Global and injury-specific process and outcome indicators were compared. RESULTS: Of 141 ATC and 69 PTC patients, injury patterns differed significantly with more TBI and abdominal injuries at the ATC and femur fractures at the PTC. Overall injury severity was greater at the ATC. Patients with solid organ injuries appeared more likely to undergo embolization or splenectomy at the ATC; however, higher injury grade and later time period were the only variables significantly associated with this. Computed tomography (CT) was used significantly more frequently at the ATC overall, most notable with panscanning and head CTs for major TBI. Time to operative management did not differ for patients with isolated femur fractures. Neuropsychological follow up after minor TBI was documented more often at the PTC than the ATC; there was no difference for those with more severe TBIs. CONCLUSIONS: Management varies for adolescents between PTCs and ATCs with more exposure to radiation and less neuropsychological follow-up of less severe TBIs at the ATC. This presents distinct opportunities to identify best policies for triage and sharing of management practices within a single regional inclusive trauma system in order to optimize short and long-term outcomes for this population. TYPE OF STUDY: Retrospective cohort. LEVEL OF EVIDENCE: Level IV.

Trauma system accreditation and patient outcomes in British Columbia: an interrupted time series analysis.

OBJECTIVE: We aim to assess the impact of several accreditation cycles of trauma centers on patient outcomes, specifically in-hospital mortality, complications and hospital length of stay. DESIGN: Interrupted time series. SETTING: British Columbia, Canada. PARTICIPANTS: Trauma patients admitted to all level I and level II trauma centers between January 2008 and March 2018. EXPOSURE: Accreditation. MAIN OUTCOMES AND MEASURES: We first computed quarterly estimates of the proportions of in-hospital mortality, complications and survival to discharge standardized for change in patient case-mix using prognostic scores and the Aalen-Johansen estimator of the cumulative incidence function. Piecewise regressions were then used to estimate the change in levels and trends for patient outcomes following accreditation. RESULTS: For in-hospital mortality and major complications, the impact of accreditation seems to be associated with short- and long-term reductions after the first cycle and only short-term reductions for subsequent cycles. However, the 95% confidence intervals for these estimates were wide, and we lacked the precision to consistently conclude that accreditation is beneficial. CONCLUSIONS: Applying a quasi-experimental design to time series accounting for changes in patient case-mix, our results suggest that accreditation might reduce in-hospital mortality and major complications. However, there was uncertainty around the estimates of accreditation. Further studies looking at clinical processes of care and other outcomes such as patient or health staff satisfaction are needed.

Qualitative Field Observation of Pedestrian Injury Hotspots: A Mixed-Methods Approach for Developing Built- and Socioeconomic-Environmental Risk Signatures.

Road traffic injuries constitute a significant global health burden; the World Health Organization estimates that they result in 1.35 million deaths annually. While most pedestrian injury studies rely predominantly on statistical modelling, this paper argues for a mixed-methods approach combining spatial analysis, environmental scans, and local knowledge for assessing environmental risk factors. Using data from the Nova Scotia Trauma Registry, severe pedestrian injury cases and ten corresponding hotspots were mapped across the Halifax Regional Municipality. Using qualitative observation, quantitative environmental scans, and a socioeconomic deprivation index, we assessed hotspots over three years to identify key social- and built-environmental correlates. Injuries occurred in a range of settings; however, clear patterns were not observed based on land use, age, or socio-economic status (SES) alone. Three hotspots revealed an association between elevated pedestrian injury and a pattern of geographic, environmental, and socio-economic factors: low- to middle-SES housing separated from a roadside attraction by several lanes of traffic, and blind hills/bends. An additional generalized scenario was constructed representing common risk factors across all hotspots. This study is unique in that it moves beyond individual measures (e.g., statistical, environmental scans, or geographic information systems (GIS) mapping) to combine all three methods toward identifying environmental features associated with pedestrian motor vehicle crashes (PMVC).

"Who is the right patient?" Insights into decisions to transfer pediatric trauma patients.

OBJECTIVE: We aim to determine what variables may influence physician decision-making about transfer of pediatric patients from a Level III Trauma Center (L3TC) to a Pediatric Trauma Center (PTC). METHODS: Emergency L3TC physicians and PTC emergency physicians/TTLs were surveyed with clinical scenarios of children presenting to a L3TC with 5 injury parameters: age, hemodynamic status, GCS, intra-abdominal injury, femur/ pelvic fracture, and asked if the patient should be transferred to a PTC. Associations between parameters and physician demographics in the decision to transfer were examined. RESULTS: One hundred seven and 94 surveys were completed at L3TCs and PTCs, respectively. Parameters associated with decision to transfer: pelvic and GI tract injuries, GCS < 12, and age < 4 years. L3TCs were significantly less likely vs. PTCs to recommend transfer with femur fracture, solid organ / GI injury, or a GCS of <13. Increasing town size, access to an experienced surgeon, and formal training in emergency medicine among L3TC physicians were associated with a decision not to transfer. CONCLUSIONS: Injuries requiring potential surgery or critical care influenced the decision to transfer. For cases with lesser severity or older ages, input of L3TCs on developing triage criteria is vital to allow families to stay in their home communities while ensuring optimal clinical outcomes. TYPE OF STUDY: Prospective Cross Sectional Survey. LEVEL OF EVIDENCE: Level III.

Where to start? Injury prevention priority scores in Canadian children.

PURPOSE: Given limited resources, it is essential to determine which Mechanisms of Injury (MOIs) to prioritize for injury prevention policy and research. We developed objective, evidence-based Injury Prevention Priority Scores (IPPSs) for Canadian children across three prevention perspectives: mortality, injury severity, and resource utilization. METHODS: We performed a retrospective cohort study of all injuries in Canada in individuals aged 0 to 19 years old from 2009 to 2014. For each MOI, an IPPS was calculated as a balanced measure of frequency and either mortality rate, median ICD-10 derived Injury Severity Score (ICISS), or median cost per hospitalization. RESULTS: Of 87,017 injuries, 83,112 were nonfatal hospitalizations, and 3905 were deaths. Overall mortality rate was 0.04 deaths/injury, median ICISS was 0.994 (IQR 0.75-0.996), and median cost per hospitalization was CAD$3262 (IQR $2118-$5001). The top three mechanisms were falls (IPPS 72), intentional self-harm (IPPS 68), and drowning (IPPS 65) for mortality, falls (IPPS73), drowning (IPPS 61), and suffocation (IPPS 61) for injury severity and falls (IPPS 70), fires (IPPS 65), and intentional self-harm (IPPS 60) for resource utilization. CONCLUSION: Falls, if prevented, would provide the most benefit to the largest proportion of the Canadian pediatric population and should be targeted for injury prevention. LEVEL OF EVIDENCE: Level III.

Optimizing postoperative follow-up in pediatric surgery (OFIPS).

BACKGROUND/PURPOSE: The purpose of the study was to determine variables associated with attending postoperative clinic follow-up (POFU) in pediatric surgical patients, predictors of clinical value, and visit cost estimates. METHODS: POFU patterns of children undergoing eight common pediatric surgical procedures over one year at a tertiary pediatric hospital were examined retrospectively. Variables associated with attending POFU and associated with predetermined measures of clinical value and cost were determined. Driving distance to hospital was chosen as a proxy measure of cost to the family. RESULTS: Six-hundred-thirty-three patients were included, and 58% attended POFU. Variables independently associated with attending follow-up included: procedure type (orchidopexy, complicated appendicitis), living close to the hospital, having a defined follow-up order, individual surgeon attending. Clinical value was identified in 16.4% of patient visits and associated with orchidopexies, having required an earlier urgent postoperative visit and longer cases considered "complex". Significant costs to the health care system (~$125,000) and families (~$15,000) could be estimated from follow-up cases that had no clinical issues identified nor required an intervention. CONCLUSION: POFU of common pediatric surgical procedures may have limited clinical value while coming at significant costs to families and the health care system. Further study is needed to define optimal needs and means of follow-up of these common pediatric surgical procedures. LEVEL OF EVIDENCE: Level III.

All-terrain vehicle serious injuries and death in children and youth: A national survey of Canadian paediatricians.

BACKGROUND: All-Terrain Vehicles (ATVs) are a leading cause of serious injury in children and youth. Certain Canadian regions have implemented legislation to promote safety, including age restrictions, mandatory training and helmet use. Jurisdictions with more stringent ATV safety legislation have been shown to have reduced injury rates in the short term. OBJECTIVES: To estimate the burden of ATV-related serious injury and death in Canada and to identify Canadian physicians' knowledge of ATV-related legislation, safety and health promotion practices. METHODS: A one-time survey was distributed to practicing paediatricians and paediatric subspecialists participating in the Canadian Paediatric Surveillance Program (CPSP) in October 2016. RESULTS: Of 2793 physicians contacted, 904 responded (32.4%). There were 181 reported cases of serious and/or fatal ATV-related injuries, including 6 deaths. Children aged 10 to 14 represented the most number of cases (n=82, 45.3%), followed by 15 to 19 (n=48, 26.5%) and 5 to 9 (n=40, 22.1%). Most cases occurred in July/August (48.3%) and May/June (25.2%), were in males (n=133, 78.2%), and occurred during recreational activity (n=139, 83.2%) or organized racing (n=6, 3.6%). In 99 cases (58.9%), the child was the driver of the ATV. Only two-thirds of respondents (67.5%) knew that ATVs should not carry passengers while under half (42.2%) never discussed ATV safety with their patients. CONCLUSIONS: ATV-related injuries and deaths in Canadian children remain a serious public health problem. Education of health care practitioners, including paediatricians, is needed to promote safety. Despite efforts to reduce ATV-related injuries, there remains a significant number of serious injuries and/deaths related to their use.

Boo-boos as the building blocks of pain expression: An observational examination of parental responses to everyday pain in toddlers.

BACKGROUND: Everyday pain experiences (minor bumps/scrapes) are common in early childhood and create frequent opportunities for socialization of pain behaviors. Nevertheless, everyday pain during the formative toddler period has been largely overlooked. AIMS: The aim of the current study was to describe the frequency and nature of toddlers' everyday pain experiences, child and parent responses, and the relationship between child characteristics (age, sex, temperament) and responses. METHODS: Fifty-two children aged 12-32 months and their parents were observed at an indoor play facility. Using an observational checklist, trained observers recorded children's everyday pain incidents and associated child and parent responses. RESULTS: Overall, 101 pain incidents were observed, the majority of which evoked low levels of pain and distress, which resolved after 1 min. Pain incidents occurred at a rate of 1.02 incidents/child/hour, with 81% of children experiencing at least one incident, which is higher than previous research with preschoolers and daycare staff. Common parent responses included a range of verbal (reassurance) and nonverbal (staying closer, hugging/kissing child) behaviors. Boys were more likely to not exhibit any protective behaviors. Parents were more likely to pick up older toddlers. CONCLUSIONS: Future research should examine the link between self-reported and observed parent responses to child pain in everyday and clinical contexts.

Contexte: Les expériences douloureuses quotidiennes (bosses et éraflures mineures), courantes chez les jeunes enfants, créent des occasions fréquentes de socialisation des comportements liés à la douleur. Néanmoins, la douleur de tous les jours pendant la période formative des tout-petits a été largement néligée.Buts: Le but de cette étude était de décrire la fréquence et la nature des expériences douloureuses de tous les jours chez les tout-petits, les réponses des enfants et des parents à ces expériences, ainsi que le lien entre les caractéristiques de l'enfant (âge, sexe, tempérament) et ces réponses.Méthodes: Cinquante-deux enfants âgés de 12 à 32 mois et leurs parents ont été observés dans un espace de jeu intérieur. À l'aide d'une grille d'observation, des observateurs dûment formés ont noté les incidents douloureux de tous les jours vécus par les enfants ainsi que les réponses des enfants et des parents à ces incidents.Résultats: Dans l'ensemble, 101 incidents douloureux ont été observés, dont la majorité a suscité des niveaux de douleur et de détresse faibles, résolus après une minute. Les incidents douloureux sont survenus à un rythme de 1,02 incident/enfant/heure et 81 % des enfants ont vécu au moins un incident, ce qui est plus élevé que les études antérieures portant sur des enfants d'âge préscolaire et le personnel de services de garde. Les réponses les plus courantes des parents comprenaient toute une gamme de comportements verbaux (rassurer) et non-verbaux (rester plus proche, étreindre ou embrasser l'enfant). Les garçons étaient plus suceptibles de ne pas démontrer de comportements de protection. Les parents étaient plus susceptibles de prendre les tout-petits plus âgés dans leurs bras.Conclusions: D'autres études devraient se pencher sur le lien entre les réponses auto-déclarées et les réponses observées des parents à la douleur de tous les jours chez les enfants ainsi qu'à la douleur dans un contaxte clinique.

Hospital and Intensive Care Unit Length of Stay for Injury Admissions: A Pan-Canadian Cohort Study.

OBJECTIVE: To assess the variation in hospital and intensive care unit (ICU) length of stay (LOS) for injury admissions across Canadian provinces and to evaluate the relative contribution of patient case mix and treatment-related factors (intensity of care, complications, and discharge delays) to explaining observed variations. BACKGROUND: Identifying unjustified interprovider variations in resource use and the determinants of such variations is an important step towards optimizing health care. METHODS: We conducted a multicenter, retrospective cohort study on admissions for major trauma (injury severity score >12) to level I and II trauma centers across Canada (2006-2012). We used data from the Canadian National Trauma Registry linked to hospital discharge data to compare risk-adjusted hospital and ICU LOS across provinces. RESULTS: Risk-adjusted hospital LOS was shortest in Ontario (10.0 days) and longest in Newfoundland and Labrador (16.1 days; P < 0.001). Risk-adjusted ICU LOS was shortest in Québec (4.4 days) and longest in Alberta (6.1 days; P < 0.001). Patient case-mix explained 32% and 8% of interhospital variations in hospital and ICU LOS, respectively, whereas treatment-related factors explained 63% and 22%. CONCLUSIONS: We observed significant variation in risk-adjusted hospital and ICU LOS across trauma systems in Canada. Provider ranks on hospital LOS were not related to those observed for ICU LOS. Treatment-related factors explained more interhospital variation in LOS than patient case-mix. Results suggest that interventions targeting reductions in low-value procedures, prevention of adverse events, and better discharge planning may be most effective for optimizing LOS for injury admissions.

Canadian benchmarks for acute injury care.

BACKGROUND: Acute care injury outcomes vary substantially across Canadian provinces and trauma centres. Our aim was to develop Canadian benchmarks to monitor mortality and hospital length of stay (LOS) for injury admissions. METHODS: Benchmarks were derived using data from the Canadian National Trauma Registry on patients with major trauma admitted to any level I or II trauma centre in Canada and from the following patient subgroups: isolated traumatic brain injury (TBI), isolated thoracoabdominal injury, multisystem blunt injury, age 65 years or older. We assessed predictive validity using measures of discrimination and calibration, and performed sensitivity analyses to assess the impact of replacing analytically complex methods (multiple imputation, shrinkage estimates and flexible modelling) with simple models that can be implemented locally. RESULTS: The mortality risk adjustment model had excellent discrimination and calibration (area under the receiver operating characteristic curve 0.886, Hosmer-Lemeshow 36). The LOS risk-adjustment model predicted 29% of the variation in LOS. Overall, observed:expected ratios of mortality and mean LOS generated by an analytically simple model correlated strongly with those generated by analytically complex models (r > 0.95, κ on outliers > 0.90). CONCLUSION: We propose Canadian benchmarks that can be used to monitor quality of care in Canadian trauma centres using Excel (see the appendices, available at canjsurg.ca). The program can be implemented using local trauma registries, providing that at least 100 patients are available for analysis.

CONTEXTE: L'issue des traitements dispensés dans les services de traumatologie d'urgence varie substantiellement d'une province canadienne et d'un centre de traumatologie à l'autre. Notre but était d'établir des valeurs de référence pour suivre la mortalité et la durée des séjours hospitaliers en traumatologie au Canada. MÉTHODES: Les paramètres ont été sélectionnés à partir des données du Registre national des traumatismes concernant les grands polytraumatisés admis dans tout centre de traumatologie de niveau I ou II au Canada et selon les catégories de patients suivantes : traumatisme crânien isolé (TCI), traumatisme thoraco-abdominal isolé, traumatisme plurisystémique fermé, âge de 65 ans ou plus. Nous avons évalué la validité prédictive à l'aide de critères discriminants et de paramètres d'étalonnage et nous avons procédé à des analyses de sensibilité pour évaluer l'impact du remplacement de méthodes analytiques complexes (imputation multiple, estimations par contraction des coefficients et modélisation flexible) par des modèles simples applicables à l'échelle locale. RÉSULTATS: Le modèle d'ajustement du risque de mortalité s'est révélé doté d'un pouvoir discriminant et d'un étalonnage excellents (aire sous la courbe de la fonction d'efficacité du récepteur [ROC] 0,886, test de Hosmer-Lemeshow 36). Le modèle d'ajustement du risque pour la durée du séjour hospitalier a permis de prédire 29 % de sa variation. De plus, les rapports observés:attendus pour la mortalité et la durée moyenne des séjours hospitaliers générés par un modèle analytique simple ont été en étroite corrélation avec les rapports générés par les modèles analytiques complexes (r > 0,95, κ pour valeurs aberrantes > 0,90). CONCLUSION: Nous proposons des valeurs de référence canadiennes qui peuvent être utilisées pour faire le suivi de la qualité des soins dans les centres de traumatologie canadiens à l'aide d'un simple programme Excel (voir les annexes, accessible à l'adresse canjsurg.ca). Le programme peut être appliqué à l'aide des données des registres de traumatologie locaux à la condition qu'au moins 100 patients y soient accessibles pour analyse.

Comparing pyloromyotomy outcomes across Canada.

BACKGROUND: Changing patterns of referral and management of hypertrophic pyloric stenosis (HPS) in North America have recently been described. Comfort with perioperative management, anesthesia, and corrective surgery have been cited as reasons for these changes. Our primary objective was to assess pyloromyotomy outcomes between different hospital types across Canada. The secondary objective was to geospatially map all pyloromyotomies to identify regions of higher HPS incidence across Canada. METHODS: Data of all pyloromyotomies done between 2011 and 2013 were acquired from Canadian Institute for Health Information (CIHI). Complication rates and length of hospital stay (LOS) were analyzed. Postal codes for each patient were used to geospatially map regions of higher HPS incidence. RESULTS: A total of 1261 pyloromyotomies were assessed. There was no difference in LOS or complication rates between different hospital types or surgeon group. Open pyloromyotomies were done in 75% of the cases. Several regions of higher HPS incidence were identified across Canada. CONCLUSION: This study found no difference in complication rate or LOS stay between hospital type and surgeon type across Canada. This may reflect a previously identified referral trend in the United States towards pediatric centers. Several regions of higher HPS incidence were identified, and may aid in identifying genetic elements causing HPS. LEVEL OF EVIDENCE: 2c.
