RESUMO
The Kids ITP Tools (KIT) is a health-related quality of life (HRQoL) questionnaire that evaluates quality of life in children with immune thrombocytopenia (ITP). There are three formats: Child Self-Report, Parent Proxy-Report and Parent Impact-Report. This study aimed to develop a domain structure by grouping-related questions from the questionnaire into domains that independently reflect various aspects of HRQoL. The study was conducted in two phases. Phase 1 involved an online survey distributed to experts to identify conceptual domains for the KIT. Phase 2 utilized a statistical approach to analyse responses from patients with ITP and their families. A revised KIT 2.0 was ultimately developed to aid in treatment decision-making and monitoring of ITP.
RESUMO
BACKGROUND: Language barriers can impact health care and outcomes. Valid and reliable language data is central to studying health inequalities in linguistic minorities. In Canada, language variables are available in administrative health databases; however, the validity of these variables has not been studied. This study assessed concordance between language variables from administrative health databases and language variables from the Canadian Community Health Survey (CCHS) to identify Francophones in Ontario. METHODS: An Ontario combined sample of CCHS cycles from 2000 to 2012 (from participants who consented to link their data) was individually linked to three administrative databases (home care, long-term care [LTC], and mental health admissions). In total, 27,111 respondents had at least one encounter in one of the three databases. Language spoken at home (LOSH) and first official language spoken (FOLS) from CCHS were used as reference standards to assess their concordance with the language variables in administrative health databases, using the Cohen kappa, sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPV). RESULTS: Language variables from home care and LTC databases had the highest agreement with LOSH (kappa = 0.76 [95%CI, 0.735-0.793] and 0.75 [95%CI, 0.70-0.80], respectively) and FOLS (kappa = 0.66 for both). Sensitivity was higher with LOSH as the reference standard (75.5% [95%CI, 71.6-79.0] and 74.2% [95%CI, 67.3-80.1] for home care and LTC, respectively). With FOLS as the reference standard, the language variables in both data sources had modest sensitivity (53.1% [95%CI, 49.8-56.4] and 54.1% [95%CI, 48.3-59.7] in home care and LTC, respectively) but very high specificity (99.8% [95%CI, 99.7-99.9] and 99.6% [95%CI, 99.4-99.8]) and predictive values. The language variable from mental health admissions had poor agreement with all language variables in the CCHS. CONCLUSIONS: Language variables in home care and LTC health databases were most consistent with the language often spoken at home. Studies using language variables from administrative data can use the sensitivity and specificity reported from this study to gauge the level of mis-ascertainment error and the resulting bias.

BACKGROUND: Prior studies have demonstrated the negative impact of language barriers on access, quality, and safety of healthcare, which can lead to health disparities in linguistic minorities. As the population ages, those with multiple chronic diseases will require increasing levels of home care and long-term services. This study described the levels of multimorbidity among recipients of home care in Ontario, Canada by linguistic group. METHODS: Population-based retrospective cohort of 510,685 adults receiving home care between April 1, 2010, to March 31, 2018, in Ontario, Canada. We estimated and compared prevalence and characteristics of multimorbidity (2 or more chronic diseases) across linguistic groups (Francophones, Anglophones, Allophones). The most common combinations and clustering of chronic diseases were examined. Logistic regression models were used to explore the main predictors of 'severe' multimorbidity (defined as the presence of five or more chronic diseases). RESULTS: The proportion of home care recipients with multimorbidity and severe multimorbidity was 92% and 44%, respectively. The prevalence of multimorbidity was slightly higher among Allophones (93.6%) than among Anglophones (91.8%) and Francophones (92.4%). However, Francophones had higher rates of cardiovascular and respiratory disease (64.9%) when compared to Anglophones (60.2%) and Allophones (61.5%), while Anglophones had higher rates of cancer (34.2%) when compared to Francophones (25.2%) and Allophones (24.3%). Relative to Anglophones, Allophones were more likely to have severe multimorbidity (adjusted OR = 1.04, [95% CI: 1.02-1.06]). CONCLUSIONS: The prevalence of multimorbidity among Ontarians receiving home care services is high; especially for whose primary language is a language other than English or French (i.e., Allophones). Understanding differences in the prevalence and characteristics of multimorbidity across linguistic groups will help tailor healthcare services to the unique needs of patients living in minority linguistic situations.

PURPOSE: Variability in practice exists in death determination by circulatory criteria in the context of organ donation. We sought to describe the practices of intensive care health care professionals for death determination by circulatory criteria with and without organ donation. METHODS: This study is a retrospective analysis of prospectively collected data. We included patients with death determination by circulatory criteria in intensive care units at 16 hospitals in Canada, three in the Czech Republic, and one in the Netherlands. Results were recorded using a checklist for the determination of death questionnaire. RESULTS: A total of 583 patients had their death determination checklist reviewed for statistical analysis. The mean (standard deviation) age in years was 64 (15). Three hundred and fourteen (54.0%) patients were from Canada, 230 (39.5%) were from the Czech Republic, and 38 (6.5%) were from the Netherlands. Fifty-two (8.9%) patients proceeded with donation after death determination by circulatory criteria (DCD). The most common diagnostic tests reported for the whole group were absent heart sounds by auscultation (81.8%), flat continuous arterial blood pressure (ABP) tracing (77.0%), and flat electrocardiogram tracing (73.2%). In patients who successfully underwent DCD (N = 52), death was determined most frequently using a flat continuous ABP tracing (94%), absent pulse oximetry (85%), and absent palpable pulse (77%). CONCLUSION: In this study, we have described practices for death determination by circulatory criteria both within and between countries. Though some variability exists, we are reassured that appropriate criteria are almost always used in the context of organ donation. In particular, the use of continuous ABP monitoring in DCD was consistent. It highlights the need for standardization of practice and up to date guidelines, especially within the context of DCD where there is both an ethical and a legal requirement to adhere to the dead donor rule, while minimizing time between death determination and organ procurement.
RéSUMé: OBJECTIF: Il existe de la variabilité dans la pratique en matière de détermination du décès selon des critères circulatoires dans le contexte d'un don d'organes. Nous avons cherché à décrire les pratiques des professionnels de la santé en soins intensifs en ce qui touche à la détermination du décès selon des critères circulatoires avec et sans don d'organes. MéTHODE: Cette étude est une analyse rétrospective de données recueillies prospectivement. Nous avons inclus des patients dont le décès avait été déterminé par des critères circulatoires dans les unités de soins intensifs de 16 hôpitaux au Canada, trois en République tchèque et un aux Pays-Bas. Les résultats ont été consignés à l'aide de la liste de contrôle d'un questionnaire sur la détermination du décès. RéSULTATS: Au total, les listes de contrôle pour la détermination du décès de 583 patients ont été examinées à des fins d'analyse statistique. L'âge moyen (écart type) en années était de 64 ans (15). Trois cent quatorze (54,0 %) patients provenaient du Canada, 230 (39,5 %) de la République tchèque et 38 (6,5 %) des Pays-Bas. Cinquante-deux (8,9 %) patients ont procédé au don après la détermination du décès selon des critères circulatoires (DCC). Les tests diagnostiques les plus fréquemment rapportés pour l'ensemble du groupe étaient l'absence de bruits cardiaques à l'auscultation (81,8 %), le tracé plat continu de la tension artérielle (TA) (77,0 %) et le tracé plat à l'électrocardiogramme (73,2 %). Chez les patients ayant été soumis avec succès à un DCD (N = 52), le décès a été déterminé le plus souvent à l'aide d'un tracé continu plat de la TA (94 %), d'une oxymétrie de pouls absente (85 %) et d'un pouls palpable absent (77 %). CONCLUSION: Dans cette étude, nous avons décrit les pratiques de détermination du décès selon des critères circulatoires à la fois à l'intérieur et entre les pays. Bien qu'il existe une certaine variabilité, nous sommes rassurés par le fait que des critères appropriés sont presque toujours utilisés dans le contexte du don d'organes. En particulier, l'utilisation du monitorage continu de la TA était constant en cas de DCC. Cela souligne la nécessité de normaliser la pratique et de disposer de lignes directrices mises à jour, en particulier dans le contexte de DCC où il existe une exigence à la fois éthique et légale de respecter la règle du donneur décédé, tout en minimisant le temps entre la détermination du décès et la collecte d'organes.

RATIONALE & OBJECTIVE: Renin-angiotensin-aldosterone system (RAAS) inhibitors are evidence-based therapies that slow the progression of chronic kidney disease (CKD) but can cause hyperkalemia. We aimed to evaluate the association of discontinuing RAAS inhibitors after an episode of hyperkalemia and clinical outcomes in patients with CKD. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Adults in Manitoba (7,200) and Ontario (n = 71,290), Canada, with an episode of de novo RAAS inhibitor-related hyperkalemia (serum potassium ≥ 5.5 mmol/L) and CKD. EXPOSURE: RAAS inhibitor prescription. OUTCOME: The primary outcome was all-cause mortality. Secondary outcomes were cardiovascular (CV) mortality, fatal and nonfatal CV events, dialysis initiation, and a negative control outcome (cataract surgery). ANALYTICAL APPROACH: Cox proportional hazards models examined the association of RAAS inhibitor continuation (vs discontinuation) and outcomes using intention to treat approach. Sensitivity analyses included time-dependent, dose-dependent, and propensity-matched analyses. RESULTS: The mean potassium and mean estimated glomerular filtration rate were 5.8 mEq/L and 41 mL/min/1.73 m2, respectively, in Manitoba; and 5.7 mEq/L and 41 mL/min/1.73 m2, respectively, in Ontario. RAAS inhibitor discontinuation was associated with a higher risk of all-cause mortality (Manitoba: HR, 1.32 [95% CI, 1.22-1.41]; Ontario: HR, 1.47 [95% CI, 1.41-1.52]) and CV mortality (Manitoba: HR, 1.28 [95% CI, 1.13-1.44]; and Ontario: HR, 1.32 [95% CI, 1.25-1.39]). RAAS inhibitor discontinuation was associated with an increased risk of dialysis initiation in both cohorts (Manitoba: HR, 1.65 [95% CI, 1.41-1.85]; Ontario: HR, 1.11 [95% CI, 1.08-1.16]). LIMITATIONS: Retrospective study and residual confounding. CONCLUSIONS: RAAS inhibitor discontinuation is associated with higher mortality and CV events compared with continuation among patients with hyperkalemia and CKD. Strategies to maintain RAAS inhibitor treatment after an episode of hyperkalemia may improve clinical outcomes in the CKD population.

BACKGROUND: Lack of appropriate temperature management has been associated with significant adverse outcomes in preterm and low birthweight neonates. There is a lack of similar investigations in the late preterm (340-366) and term (≥370) neonate population. Our aim was to identify key risk factors as well as clinical outcomes associated with hypothermia in this population. METHODS: A retrospective chart review was conducted at the Ottawa Hospital including all eligible infants ≥340 weeks' gestation over a one-month period in November 2020. Infant, maternal, and delivery room variables were collected, including prematurity, maternal temperature, delivery mode, birthweight, and premature rupture of membranes, as well as clinical outcomes such as NICU/SCN admission and length of stay. Regression models were generated, adjusted for covariates, and stepwise regression was performed. RESULTS: Four hundred forty infants were included in the analysis; 26.8% (118/440) were hypothermic within 6 hours of delivery. In the multivariable analysis, prematurity, low 5 minute Apgar score (< 7) or need for resuscitation, maternal hypertension, and absence of premature rupture of membranes > 18 hours or suspected maternal infection were significantly associated with hypothermia within 6 hours of delivery (p < 0.05). Multivariable analysis of clinical outcomes demonstrated a significant association between hypothermia within 6 hours of delivery and NICU/SCN admission (OR = 2.87; 95% CI 1.36, 6.04), need for respiratory support or diagnosis of respiratory distress syndrome (OR = 3.94; 95% CI 1.55, 10.50), and length of stay (exp(ß) = 1.20; 95% bootstrap CI 1.04, 1.37). CONCLUSIONS: Our results suggest there are similar factors associated with hypothermia in our study population of infants born at ≥340 weeks' gestation compared to prior studies in preterm and low-birthweight infants. Furthermore, hypothermia is associated with higher risk of adverse outcomes, which highlights the need to prevent hypothermia in all newborns.

BACKGROUND: Individuals who are homeless have complex health care needs, which contribute to the frequent use of health services. In this study, we investigated the relationship between housing and health care utilization among adults with a history of homelessness in Ontario. METHODS: Survey data from a 4-year prospective cohort study were linked with administrative health records in Ontario. Annual rates of health encounters and mean costs were compared across housing categories (homeless, inconsistently housed, housed), which were based on the percentage of time an individual was housed. Generalized estimating equations were applied to estimate the average annual effect of housing status on health care utilization and costs. RESULTS: Over the study period, the proportion of individuals who were housed increased from 37% to 69%. The unadjusted rates of ambulatory care visits, prescription medications, and laboratory tests were highest during person-years spent housed or inconsistently housed and the rate of emergency department visits was lowest during person-years spent housed. Following adjustment, the rate of prescription claims remained higher during person-years spent housed or inconsistently housed compared with the homeless. Rate ratios for other health care encounters were not significant (P>0.05). An interaction between time and housing status was observed for total health care costs; as the percentage of days housed increased, the average costs increased in year 1 and decreased in years 2-4. CONCLUSIONS: These findings highlight the effects of housing on health care encounters and costs over a 4-year study period. The rate of prescription medications was higher during person-years spent housed or inconsistently housed compared with the homeless. The cost analysis suggests that housing may reduce health care costs over time; however, future work is needed to confirm the reason for the reduction in total costs observed in later years.

BACKGROUND: Frailty is a geriatric syndrome that leaves people vulnerable to adverse outcomes. In cardiac surgery, minimal data describe associations between frailty and patient-centred outcomes. Our objective was to estimate the association between frailty and days alive at home after cardiac surgery. METHODS: We conducted a population-based cohort study using linked health administrative data in the Canadian province of Ontario. All individuals >65 yr at the time of cardiac surgery were assigned a frailty score using a validated frailty index. Days alive and at home in the 30 and 365 days after surgery were calculated. The unadjusted and adjusted associations between frailty and days alive at home were calculated. RESULTS: We identified 61 389 patients from 2009 to 2015. Frailty was associated with reduced days at home within 30 days (adjusted ratio of means for every 10% increase in frailty=0.79; 95% confidence interval [CI], 0.78-0.81; P<0.0001) and 365 days (adjusted ratio of means for every 10% increase in frailty=0.92; 95% CI, 0.91-0.93; P<0.0001) of surgery. Results were consistent in sensitivity analyses (5.0 fewer days alive at home [95% CI, 4.8-5.2] within 30 days and 9.0 fewer days alive at home [95% CI, 8.7-9.2] within 365 days after surgery). CONCLUSION: Frailty is associated with a reduction in days alive at home after major cardiac surgery. This information should be considered in prognostic discussions before surgery and in care planning for vulnerable older patient groups. Days alive at home may be a useful outcome for routine measurement in quality, reporting, and studies using routinely collected data.

OBJECTIVES: The purpose of the present study was to assess longitudinal associations between positive and harsh parenting in childhood and adolescent mental and behavioral difficulties. METHODS: Data were drawn from Canada's population-based National Longitudinal Survey of Children and Youth (data collected from 1994 to 2009, analyzed 2018). The sample included 9,882 adolescents aged 12/13 years old. Parents self-reported positive and harsh parenting when children were 6/7, 8/9, and 10/11 years old. Symptoms of depression/anxiety, hyperactivity, physical aggression, social aggression, and suicidal ideation were self-reported by adolescents at age 12/13. Linear regression was used to examine the associations between parenting behaviors at each age and adolescent psychiatric symptoms, adjusted for children's baseline symptoms. RESULTS: Harsh parenting at 10/11 was associated with elevated symptoms of early-adolescent physical aggression, social aggression, and suicidal ideation for boys only, and for all children at earlier ages. Beginning at age 8/9, harsh discipline was associated with elevated symptoms of depression/anxiety for boys only. Overall, positive parenting at age 6/7 was protective against depression/anxiety, physical aggression, and social aggression. Significant sex differences emerged beginning at age 8/9, with positive parenting associated with higher symptoms of depression/anxiety for boys only. Positive parenting at age 10/11 was associated with increased depression/anxiety, physical aggression, social aggression, and suicidal ideation among boys, but decreased symptoms of physical aggression, social aggression, and suicidal ideation among girls. CONCLUSIONS: Results suggest that the impact of positive and harsh parenting may depend on age and sex, with harsh parenting being more detrimental to boys as they approach adolescence.

BACKGROUND: Depression and anxiety disorders are highly comorbid, and share significant symptom overlap. Whereas depression has been consistently associated with excess mortality, the association between anxiety and mortality is less clear. Our aim was to identify constellations of anxious and depressive symptoms and examine their associations with mortality. METHOD: This study considers respondents from the 1970 (n = 1203) and 1992 (n = 1402) cohorts of the Stirling County study. Symptoms of depression and anxiety were assessed using structured at-home interviews. Vital status of participants through 2011 was determined using probabilistic linkages to the Canadian Mortality Database. RESULTS: Exploratory factor analysis yielded three correlated factors in each cohort. Items loading on each factor varied slightly between cohorts, but roughly corresponded to (1) depressive symptoms, (2) anxious symptoms, and (3) somatic symptoms. The depressive factor was associated with increased risk of mortality in both the 1970 (HR: 1.35, 95% CI: 1.12, 1.62) and 1992 (HR: 1.25, 95% CI: 1.05, 1.48) cohorts. Anxious symptoms were associated with a reduced risk of mortality in the 1992 sample (HR: 0.72; 95% CI: 0.53, 0.90). Somatic symptoms were associated with a reduced risk of mortality in the 1970 sample (HR: 0.83, 95% CI: 0.69, 0.99), but an elevated risk of mortality in the 1992 sample (HR: 1.29; 95% CI: 1.11, 1.51). CONCLUSIONS: This study provides evidence that symptoms of depression and anxiety may have differential associations with early mortality. Somatic symptoms such as upset stomach and loss of appetite may be protective against mortality, perhaps through increased use of health care services. Conversely, symptoms such as weakness and cold sweats may be indicative of failing health.

BACKGROUND: Many studies have shown that depression increases mortality risk. We aimed to investigate the duration of time over which depression is associated with increased risk of mortality, secular trends in the association between depression and mortality, and sex differences in the association between depression and mortality. METHODS: We conducted a cohort study of 3410 adults enrolled in 3 representative samples of a county in Atlantic Canada in 1952 (n = 1003), 1970 (n = 1203) or 1992 (n = 1402) (the Stirling County Study). Depression was measured using a diagnostic algorithm based on the presence of depressed mood and associated symptoms, duration of more than 1 month, and substantial impairment. Vital status of participants through 2011 was determined using probabilistic linkages to the Canadian Mortality Database. RESULTS: Depression was associated with a heightened risk of mortality among men during the 3 time periods of the study, with hazard ratios (HRs) of 2.90 (95% confidence interval [CI] 1.69-4.98) between 1952 and 1967, 1.97 (CI 1.34-2.89) between 1968 and 1990, and 1.52 (CI 1.09-2.13) between 1991 and 2011. Elevated risk of mortality was noted among women only between 1990 and 2011 (HR = 1.51; CI = 1.11-2.05). INTERPRETATION: The association between depression and mortality persists over long periods of time and has emerged among women in recent decades, despite contemporaneous improvements in the treatment of depression and reduction of stigma associated with depression. Further research is needed to better understand the mechanisms involved.

OBJECTIVES: To determine the association between neighborhood marginalization and rates of pediatric ED visits in Ottawa, Ontario. Secondary objectives investigated if the association between neighborhood marginalization and rates varied by year, acuity, and distance to hospital. METHODS: We calculated rates of pediatric ED visits per 1000 person-years for census dissemination areas within 100 km of the Children's Hospital of Eastern Ontario for patients < 18 years old from January 2018 through December 2020. The 2016 Ontario Marginalization Index categorized neighborhoods along quintiles of residential instability, material deprivation, ethnic concentration, and dependency. Generalized mixed-effects models determined the incidence rate ratios of pediatric ED visits for each quintile of marginalization; multivariate models were used to control for year of presentation and distance to hospital. Analysis was repeated for low versus high acuity ED visits. RESULTS: There were 154,146 ED visits from patients in 2055 census dissemination areas within 100 km of CHEO from 2018 to 2020. After controlling for year and distance from hospital in multivariate analyses, there were higher rates of pediatric ED visits for dissemination areas with high residential instability, high material deprivation, and low ethnic concentration. These findings did not change according to visit acuity. CONCLUSIONS: Neighborhood residential instability and material deprivation should be considered when locating alternatives to emergency care.
RéSUMé: OBJECTIFS: Déterminer l'association entre la marginalisation du quartier et les taux de visites aux urgences pédiatriques à Ottawa, en Ontario. Les objectifs secondaires visaient à déterminer si l'association entre la marginalisation du quartier et les taux variait selon l'année, l'acuité et la distance à l'hôpital. MéTHODES: Nous avons calculé les taux de visites aux urgences pédiatriques par tranche de 1000 années-personnes dans les aires de diffusion du recensement à moins de 100 km du Centre hospitalier pour enfants de l'est de l'Ontario pour les patients de moins de 18 ans de janvier 2018 à décembre 2020. L'Indice de marginalisation de l'Ontario de 2016 classait les quartiers selon des quintiles d'instabilité résidentielle, de privation matérielle, de concentration ethnique et de dépendance. Les modèles à effets mixtes généralisés ont déterminé les ratios des taux d'incidence des visites aux urgences pédiatriques pour chaque quintile de marginalisation; des modèles multivariés ont été utilisés pour contrôler l'année de présentation et la distance à l'hôpital. L'analyse a été répétée pour les visites à l'urgence de faible acuité par rapport à haute acuité. RéSULTATS: Il y a eu 154 146 visites aux urgences de patients dans 2 055 aires de diffusion du recensement à moins de 100 km du CHEO de 2018 à 2020. Après avoir tenu compte de l'année et de la distance par rapport à l'hôpital dans les analyses multivariées, on a constaté des taux plus élevés de visites aux urgences pédiatriques dans les zones de diffusion présentant une instabilité résidentielle élevée, une privation matérielle élevée et une faible concentration ethnique. Ces résultats n'ont pas changé selon l'acuité de la visite. CONCLUSIONS: L'instabilité résidentielle du quartier et la privation matérielle doivent être prises en compte lors de la recherche de solutions de rechange aux soins d'urgence.

Background: Knowledge of time to positivity (TTP) for blood cultures is useful to assess timing of discontinuation of empiric antimicrobials for suspected bacteremia with no focus. Methods: An audit of positive blood cultures from the Children's Hospital of Eastern Ontario (CHEO) from November 1, 2019, to October 31, 2020, was performed to determine TTP, defined as the start of incubation to a positive signal from automated incubators. Results: Three hundred seventy-six positive blood cultures were identified from 248 patients (average age: 6.27 [SD 6.24] years). Of these, 247 isolates were speciated; 90 (36.4%) were definitive/probable (DP) pathogens (median TTP 12.75 hours) and 157 (63.6%) possible/probable (PP) contaminants (median TTP 24.08 hours). At each time point, the adjusted rate of positive blood culture was significantly higher for DP pathogens compared to PP contaminants (hazard ratio [HR] 1.80 [95% CI 1.37, 2.36]) and for children ≤27 days old compared to the oldest age group (HR 1.94 [95% CI 1.19, 3.17]). By 36 hours, the proportion of positive cultures was significantly higher in the youngest age group (≤27 days) compared with the 3-11 years old age group (91.7% [95% CI 68.6%, 97.8%] versus 58.2% [95% CI 46.91%, 68.06%]). Conclusion: Across all ages, the TTP was significantly shorter for blood cultures with DP pathogens compared to those with PP contaminants (HR 1.80 [95% CI 1.37, 2.36]). In newborns, 90% of blood cultures were positive by 36 hours supporting this re-assessment time for empiric antimicrobials. TTP was longer in children ≥12 months, possibly related to other factors such as blood culture volume.
Historique: Il est utile de connaître le délai de positivité (DdP) des hémocultures pour évaluer le moment de mettre un terme aux antimicrobiens empiriques en cas de présomption de bactériémie sans source apparente. Méthodologie: Les chercheurs ont procédé à un audit des hémocultures positives du Centre hospitalier pour enfants de l'est de l'Ontario (CHEO) entre le 1er novembre 2019 et le 31 octobre 2020 pour déterminer le DdP, défini comme la période entre le début de l'incubation et le signal positif d'incubateurs automatisés. Résultats: Les chercheurs ont extrait 376 hémocultures positives provenant de 248 patients (d'un âge moyen de 6,27 ± 6,24 ans). De ce nombre, ils ont différencié 247 isolats, dont 90 (36,4 %) étaient des agents pathogènes confirmés ou probables (CP) (DdP médian de 12,75 heures) et 157 (63,6 %), des contaminants possibles ou probables (PP) (DdP médian de 24,08 heures). À chaque point temporel, le taux corrigé d'hémocultures positives était sensiblement plus élevé à l'égard des agents pathogènes CP que des contaminants PP (rapport de risque instantanés [RRI] : 1,80 [IC à 95 % 1,37,2,36]) et des nouveau-nés de 27 jours de vie ou moins que des enfants plus âgés (RRI 1,94 [IC à 95 % 1,19,3,17]). Au bout de 36 heures, la proportion de cultures positives était sensiblement plus élevée dans le groupe le plus jeune (27 jours de vie ou moins) que dans celui des enfants de trois à 11 ans, soit de 91,7 % (IC à 95 % 68,6 %, 97,8 %) par rapport à 58,2 % (IC à 95 % 46,91 %, 68,06 %). Conclusion: À tout âge, le DdP était sensiblement plus court, à l'égard des hémocultures contenant des agents pathogènes CP que des contaminants PP (RRI 1,80 [IC à 95 % 1,37,2,36]). Chez les nouveau-nés, 90 % des hémocultures sont positives au bout de 36 heures, ce qui appuie ce moment pour réévaluer la prise d'antimicrobiens empiriques. Le DdP était plus long chez les enfants âgés de plus de 12 mois, peut-être à cause d'autres facteurs comme le volume de l'hémoculture.
RESUMO
Background: Organ and Tissue Donation Coordinators (OTDCs) are key to the success of deceased organ donation processes. However, reduced resilience can leave them susceptible to the incidence of work-related issues and decrease the quality of the care provided. Therefore, this study aimed to examine the extent of resilience and influencing aspects among OTDCs in Canada. Methods: Mixed-method (QUAN-qual) explanatory sequential design. Quantitative data was collected using an online cross-sectional survey approach with demographic data and the validated scales and analyzed using descriptive and inferential statistics. Qualitative data was collected using a descriptive approach with a semi-structured interview guide and analyzed using content analysis. Results: One hundred twenty participants responded to the survey, and 39 participants were interviewed. Most participants from the survey were female (82%), registered nurses (97%) and on average 42 years old. The quantitative data revealed that OTDCs had a high level of perceived compassion satisfaction (ProQOL-CS = 36.3) but a resilience score (CD-RISC = 28.5) lower than other groups of healthcare professionals. OTDCs with over a year of experience in the role were more likely to have higher levels of resilience. The qualitative data identified that participants saw resilience as crucial for their work-related well-being. Although coping strategies were identified as a key factor that enhance resilience, many OTDCs reported difficulty in developing healthy coping strategies, and that the use of unhealthy mechanisms (e.g., alcohol and smoking) can result in negative physical consequences (e.g., weight gain) and reduced resilience levels. Conclusion: Participants reported using a series of coping and protective strategies to help build resilience, but also difficulty in developing healthy mechanisms. The lack of healthy coping strategies were seen as contributing to negative work-related issues (e.g., burnout). Our findings are being used to develop tailored interventions to improve resilience and healthy coping strategies among organ donor coordinators in Canada.

INTRODUCTION: Life-prolonging therapies (LPTs) are rapidly evolving for the treatment of advanced prostate cancer, although factors associated with real-world uptake are not well characterized. METHODS: In this cohort of prostate-cancer decedents, we analyzed factors associated with LPT access. Population-level databases from Ontario, Canada identified patients 65 years or older with prostate cancer receiving androgen deprivation therapy and who died of prostate cancer between 2013 and 2017. Univariate and multivariable analyses assessed the association between baseline characteristics and receipt of LPT in the 2 years prior to death. RESULTS: Of 3575 patients who died of prostate cancer, 40.4% (n = 1443) received LPT, which comprised abiraterone (66.3%), docetaxel (50.3%), enzalutamide (17.2%), radium-223 (10.0%), and/or cabazitaxel (3.5%). Use of LPT increased by year of death (2013: 22.7%, 2014: 31.8%, 2015: 41.8%, 2016: 49.1%, and 2017: 57.9%, p < 0.0001), driven by uptake of all agents except docetaxel. Adjusted odds of use were higher for patients seen at Regional Cancer Centers (OR: 1.8, 95% CI: 1.5-2.1) and who received prior prostate-directed therapy (OR: 1.3, 95% CI: 1.0-1.5), but lower with advanced age (≥85: OR: 0.54, 95% CI:0.39-0.75), increased chronic conditions (≥6: OR: 0.62, 95% CI: 0.43-0.92), and long-term care residency (OR: 0.38, 95% CI: 0.17-0.89). Income, stage at presentation, and distance to the cancer center were not associated with LPT uptake. CONCLUSION: In this cohort of prostate cancer-decedents, real-world uptake of novel prostate cancer therapies occurred at substantially higher rates for patients receiving care at Regional Cancer Centers, reinforcing the potential benefits for treatment access for patients referred to specialist centers.

Purpose: To examine the publication patterns of pediatric neurology articles in general pediatric, general neurology, and neurology subspecialty journals using a bibliometric approach. Methods: The top 5 journals in general pediatrics, general neurology and neurology subspecialties were identified using the 2017 Journal Citations Report (JCR). For general pediatric journals, we selected 4 pediatric subspecialties for comparison of publication patterns with neurology: immunology, endocrinology, gastroenterology, and respirology. For general neurology and neurology subspecialty journals, we searched both the top 5 neurology and neurology subspecialty journals for pediatric articles. Using Ovid Medline, we identified articles published between 2009-2017. Results: With regards to child neurology-based articles, 1501 were published in general pediatrics journals, 643 in general neurology journals and 685 in neurology subspecialty journals. Examination of the top pediatric journals revealed that Pediatrics published the most neurology-based articles. Neurology-based studies were published more frequently than other pediatric subspecialty studies. Of the top general neurology Neurology published the most child neurology-based articles, while Epilepsia published the most child neurology-based articles out of neurology subspecialty journals. Cohort studies were the most frequent study type across all journals. Conclusion: Our study revealed that child neurology articles are published more often in pediatric journals as opposed to general neurology and neurology subspecialty journals. We also found that in general pediatric journals, neurology-based articles are published more frequently compared to other specialties. Our results provide guidance to authors when considering submission of their pediatric neurology research.
RESUMO
INTRODUCTION: Villitis of unknown etiology (VUE) is associated with fetal growth restriction (FGR) and adverse short-term neonatal outcomes. No investigation to date has found which VUE features are driving the association with FGR diagnosis. METHODS: A retrospective cohort study of placenta pathology specimens (2013-2017) was conducted. Independent variables of interest were: VUE distribution (focal vs diffuse), location (basal vs non-basal), and grade (high vs low). The primary outcome was FGR, and secondary outcomes were neonatal intensive care unit (NICU) admission, NICU length of stay, Apgar scores <7 at 1, 5, and 10-min, and recurrence rate of villitis in subsequent pregnancies. Association between VUE characteristics and our primary outcome were investigated using logistic regression. Secondary outcomes were explored with regression analyses and recurrence rate of VUE for members of the cohort with a recorded subsequent pregnancy was calculated. RESULTS: One hundred and twenty seven placentas were included. Adjusted models showed no difference in the odds of FGR between high-grade versus low-grade VUE [aOR 1.25 95% CI (0.50, 3.26), p = 0.6], focal/multi-focal vs diffuse cases [aOR 1.03 95% CI (0.28, 4.34), p = >0.9], and basal vs non-basal VUE [aOR 0.06 95% CI (0.00, 1.10), p = 0.058]. After adjusting for prematurity <37 weeks, there were lower odds of NICU admission in basal vs non-basal cases [aOR 0.25, 95% CI (0.06, 0.90), p = 0.048). There was no difference in the odds of neonates presenting with Apgar <7 for the distinct VUE histopathology features. Three cases had recurrent VUE, resulting in a 6.8% [95% CI (3.02%, 10.61%)] recurrence rate. All recurrent cases were high-grade and identified with basal localization. DISCUSSION: There are no statistical associations between distinct VUE features and FGR diagnosis, however location of villitis may be associated with worse neonatal outcomes. Villitis of any type (severity, degree, location) could potentially drive insufficient placental function and poor fetal growth.

Introduction: Therapeutic hypothermia (TH) within 6 hours after birth is known to improve both survival and neurodevelopmental outcomes in neonates with hypoxic ischemic encephalopathy (HIE). Meeting this recommended target temperature for neonates who require transport for TH treatment can be complex for various reasons. This study aimed to reduce the time from birth to the initiation of TH and target temperature, thereby increasing the proportion of transported neonates reaching target temperature within 6 hours to >50%. Methods: We evaluated the effect of three quality improvement interventions, including revised transport team processes, outreach education/resources, and the use of a servo-controlled cooling device on land transports. We compared key outcome TH metrics for cohorts before and after implementation. Results: The study team compared baseline data for 77 to 102 neonates born between 2009 and April 2015 (preintervention) and September 2015 and September 2020 (postintervention(s)). We observed reductions in both the time from birth to the initiation of passive cooling (38%) and time to reach target TH temperature (23%), with an increase in the proportion of neonates reaching target temperature by 6 hours of age from 50% to 71%. Conclusions: We used quality improvement methodology to identify key areas for intervention(s) and improvement. Targeted interventions have successfully and consistently improved the timing and delivery of TH to neonates with hypoxic ischemic encephalopathy within the transport environment, with a 20% increase in neonates reaching target temperature by 6 hours of age.
RESUMO
Background: Routinely used cardiac medications, based on pharmacokinetics, are hypothesized to increase drug levels of direct oral anticoagulants (DOACs), with the potential to increase the risk of hemorrhage. We set out to compare the risk for hemorrhage following initiation of amiodarone, verapamil, or diltiazem (moderate cytochrome P450 3A4 and/or P-glycoprotein activity) vs metoprolol or amlodipine (weak or no activity), among older adults prescribed DOACs. Methods: We conducted a population-based, retrospective cohort study of all adults (aged ≥ 66 years) on a DOAC (dabigatran, apixaban, rivaroxaban; n = 295,038) who were newly prescribed amiodarone (n = 4872), verapamil (n = 1284), or diltiazem (n = 14,638), compared with metoprolol or amlodipine, from Ontario, Canada (2009-2016). The outcome was hospital admission or emergency room visit with a major hemorrhage (upper or lower gastrointestinal tract, intracranial), examined using weighted models. Results: A total of 1737 hemorrhage events occurred (amiodarone, 80 [1.6%] vs metoprolol 503 [2.3%]; verapamil, 32 [2.5%] vs amlodipine, 406 [1.6%]; diltiazem, 312 [2.1%] vs amlodipine, 404 [1.5%]). The weighted risk of major hemorrhage was not elevated with amiodarone, verapamil, or diltiazem initiation in DOAC users, compared to metoprolol or amlodipine, during the full follow-up period (hazard ratio [HR; 95% confidence interval]: amiodarone HR 0.77 [0.61-0.97]; verapamil HR 1.32 [0.88-1.98]; diltiazem HR 0.99 [0.85-1.15]). This finding was consistent with a broader definition of bleeding, adjusting for kidney function, by DOAC type or dosage. Conclusions: Hemorrhage risk with amiodarone, verapamil, and diltiazem was similar to that with comparators, among DOAC users aged > 66 years.
Contexte: Les médicaments cardiaques couramment utilisés, selon la pharmacocinétique, devraient théoriquement augmenter les taux d'anticoagulants oraux directs (AOD), ce qui s'accompagne d'un risque accru d'hémorragie. Nous avons entrepris de comparer le risque d'hémorragie après l'instauration de l'amiodarone, du vérapamil ou du diltiazem (activité modérée du cytochrome P450 3A4 ou de la P-glycoprotéine) par rapport au métoprolol ou à l'amlodipine (activité faible ou nulle), chez des personnes âgées à qui l'on avait prescrit des AOD. Méthodologie: Nous avons mené une étude de cohortes rétrospective en population auprès de tous les adultes (âgés de 66 ans et plus) prenant un AOD (dabigatran, apixaban, rivaroxaban; n = 295 038) à qui l'on venait de prescrire de l'amiodarone (n = 4872), du vérapamil (n = 1284) ou du diltiazem (n = 14 638), comparativement au métoprolol ou à l'amlodipine, en Ontario, au Canada (2009-2016). Le critère d'évaluation était une admission à l'hôpital ou une consultation à l'urgence pour une hémorragie grave (voie gastro-intestinale supérieure ou inférieure, intracrânienne), examiné à l'aide de mo-dèles pondérés. Résultats: Au total, 1 737 événements hémorragiques sont survenus (amiodarone, 80 [1,6 %] contre métoprolol, 503 [2,3 %]; vérapamil, 32 [2,5 %] contre amlodipine, 406 [1,6 %]; diltiazem, 312 [2,1 %] contre amlodipine, 404 [1,5 %]). Le risque pondéré d'hémorragie grave ne s'est pas accru avec l'instauration de l'amiodarone, du vérapamil ou du diltiazem chez les utilisateurs d'AOD, comparativement au métoprolol ou à l'amlodipine, pendant toute la période de suivi (rapport des risques instantanés [RRI; intervalle de confiance à 95 %] : amiodarone : RRI 0,77 [0,61-0,97]; vérapamil : RRI 1,32 [0,88-1,98]; diltiazem : RRI 0,99 [0,85-1,15]). Ce résultat concorde avec une définition plus large du saignement, après ajustement pour la fonction rénale, par type ou posologie d'AOD. Conclusions: Le risque d'hémorragie associé à l'amiodarone, au vérapamil et au diltiazem était semblable à celui des médicaments de comparaison chez les utilisateurs d'AOD âgés de plus de 66 ans.
RESUMO
BACKGROUND: Rurality strongly correlates with higher pay-for-performance access bonuses, despite higher emergency department use and fewer primary care services than in urban settings. We sought to evaluate the relation between patient-reported access to primary care and access bonus payments in urban settings. METHODS: We conducted a cross-sectional, secondary data analysis using Ontario survey and health administrative data from 2013 to 2017. We used administrative data to calculate annual access bonuses for eligible urban family physicians. We linked this payment data to adult (≥ 16 yr) patient data from the Health Care Experiences Survey to examine the relation between access bonus achievement (in quintiles of the proportion of bonus achieved, from lowest [Q1, reference category] to highest [Q5]) and 4 patient-reported access outcomes. The average survey response rate to the patient survey during the study period was 51%. We stratified urban geography into large, medium and small settings. In a multilevel regression model, we adjusted for patient-, physician- and practice-level covariates. We tested linear trends, adjusted for clustering, for each outcome. RESULTS: We linked 18 893 respondents to 3940 physicians in 414 bonus-eligible practices. Physicians in small urban settings earned the highest proportion of their maximum potential access bonuses. Access bonus achievement was positively associated with telephone access (Q2 odds ratio [OR] 1.18, 95% confidence interval [CI] 0.98-1.42; Q3 OR 1.34, 95% CI 1.10-1.63; Q4 OR 1.46, 95% CI 1.19-1.79; Q5 OR 1.87, 95% CI 1.50-2.33), after hours access (Q2 OR 1.26, 95% CI 1.09-1.47; Q3 OR 1.46, 95% CI 1.23-1.74; Q4 OR 1.77, 95% CI 1.46-2.15; Q5 OR 1.88, 95% CI 1.52-2.32), wait time for care (Q2 OR 1.01, 95% CI 0.85-1.20; Q3 OR 1.17, 95% CI 0.97-1.41; Q4 OR 1.27, 95% CI 1.05-1.55; Q5 OR 1.63, 95% CI 1.32-2.00) and timeliness (Q2 OR 1.29, 95% CI 0.98-1.69; Q3 OR 1.29, 95% CI 0.94-1.77; Q4 OR 1.58, 95% CI 1.16-2.13; Q5 OR 1.98, 95% CI 1.38-2.82). When stratified by geography, we observed several of these associations in large urban settings, but not in small urban settings. Trend tests were statistically significant for all 4 outcomes. INTERPRETATION: Although the access bonus correlated with access in larger urban settings, it did not in smaller settings, aligning with previous research questioning its utility in smaller geographies. The access bonus may benefit from a redesign that considers geography and patient experience.
