Abstract
BACKGROUND Indigenous Peoples experience health inequities and racism across the continuum of health services. We performed a systematic review and meta-analysis of the incidence and outcomes of critical illness among Indigenous Peoples. METHODS We searched Ovid MEDLINE/PubMed, Ovid EMBASE, Google Scholar, and Cochrane Central Register of Controlled Trials (inception to October 2022). Observational studies, case series of > 100 patients, clinical trial arms, and grey literature reports of Indigenous adults were eligible. We assessed risk of bias using the Newcastle-Ottawa Scale and appraised research quality from an Indigenous perspective using the Aboriginal and Torres Strait Islander Quality Assessment Tool. ICU mortality, ICU length of stay, and invasive mechanical ventilation (IMV) were compared using risk ratios and mean difference (MD) for dichotomous and continuous outcomes, respectively. ICU admission was synthesized descriptively. RESULTS Fifteen studies (Australia and/or New Zealand [n = 12] and Canada [n = 3]) were included. Risk of bias was low in 10 studies and moderate in 5, and included studies had minimal incorporation of Indigenous perspectives or consultation. There was no difference in ICU mortality between Indigenous and non-Indigenous (RR 1.14, 95%CI 0.98 to 1.34, I2 = 87%). We observed a shorter ICU length of stay among Indigenous (MD - 0.25; 95%CI, - 0.49 to - 0.00; I2 = 95%) and a higher use for IMV among non-Indigenous (RR 1.10; 95%CI, 1.06 to 1.15; I2 = 81%). CONCLUSION Research on Indigenous Peoples experience with critical care is poorly characterized and has rarely included Indigenous perspectives. ICU mortality between Indigenous and non-Indigenous populations was similar, while there was a shorter ICU length of stay and less mechanical ventilation use among Indigenous patients.

Abstract
BACKGROUND Indigenous Peoples experience health inequities across the continuum of health services. Improvements for Indigenous patients and their families during vulnerable experiences with the healthcare system may have a significant impact on the patient experience and outcomes. Improved understanding of the occurrence of critical illness in Indigenous Peoples and their use of critical care services, as a strategic priority, may aid in the development of initiatives for improving health equity. A global focus was selected to learn from Indigenous populations' experiences with critical care, as the understanding of critical illness among Indigenous Peoples in Canada is not well understood. This protocol outlines a systematic review focused on describing the incidence of critical illness and utilization of critical care services among Indigenous Peoples. METHODS Ovid MEDLINE/PubMed, Ovid EMBASE, Google Scholar, and Cochrane Central Register of Controlled Trials will be searched. Relevant Canadian sites for gray literature (National Collaborating Centre for Indigenous Health, First Nations Health Authority, Canadian Institutes of Health Research Institute of Indigenous Peoples' Health, National Association of Friendship Centres, the Alberta First Nations Information Governance Centre, Métis Nation of Alberta) will also be searched. We will include studies of adults (≥18 years) either without critical illness (i.e., general population) or with critical illness (i.e., admitted to an intensive care unit (ICU)). The exposure of interest will be Indigenous identity. Primary outcome measures are ICU admission and ICU mortality. Because heterogeneity in populations, comparisons, and outcome measures is anticipated, it is likely that the findings will be summarized using a narrative synthesis. A meta-analysis will be performed if there is sufficient evidence on one or more outcomes of interest. DISCUSSION This systematic review will provide a better understanding of the epidemiology, risk factors, and outcomes of critical illness and utilization of critical care services among Indigenous Peoples. The knowledge generated will be applied to a broader program of work designed to create ethical space to co-design, implement, and evaluate a culturally competent, safe, and innovative model for critical care services for Indigenous People.

[PMID: 34320910 PMCID: PMC8330756 DOI: 10.1080/22423982.2021.1946324] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 06/14/2021] [Accepted: 06/17/2021] [Indexed: 11/25/2022] Open
Abstract
A recent report by the Chief Public Health Officer of Canada demonstrates the inferior health status of Indigenous Peoples in Canada when compared to non-Indigenous populations. This scoping review maps out the available literature concerning acute health care for Indigenous Peoples in Canada in order to better understand the health care issues they face. All existing articles concerning health care provided to Indigenous Peoples in Canada in acute settings were included in this review. The targeted studied outcomes were access to care, health care satisfaction, hospital visit rates, mortality, quality of care, length of stay and cost per hospitalisation. 114 articles were identified. The most studied outcomes were hospitalisation rates (58.8%), length of stay (28.0%), mortality (25.4%) and quality of care (24.6%) Frequently studied topics included pulmonary disease, injuries, cardiovascular disease and mental illness. Indigenous Peoples presented lower levels of satisfaction and access to care although they tend to be over-represented in hospitalisation rates for acute care. Greater inclusion of Indigenous Peoples in the health care system and in the training of health care providers is necessary to ensure a better quality of care that is culturally safe for Indigenous Peoples.

Abstract
PURPOSE Collection and analysis of health data are crucial to achieving high-quality clinical care, research, and quality improvement. This review explores existing hospital, regional, provincial and national data platforms in Canada to identify gaps and barriers, and recommend improvements for data science. SOURCE The Canadian Critical Care Trials Group and the Canadian Critical Care Translational Biology Group undertook an environmental survey using list-identified names and keywords in PubMed and the grey literature, from the Canadian context. Findings were grouped into sections, corresponding to geography, purpose, and patient sub-group initiatives, using a narrative qualitative approach. Emerging themes, impressions, and recommendations towards improving data initiatives were generated. PRINCIPAL FINDINGS In Canada, the Canadian Institute for Health Information Discharge Abstract Database contains high-level clinical data on every adult and child discharged from acute care facilities; however, it does not contain data from Quebec, critical care-specific severity of illness risk-adjustment scores, physiologic data, or data pertaining to medication use. Provincially mandated critical care platforms in four provinces contain more granular data, and can be used to risk adjust and link to within-province data sets; however, no inter-provincial collaborative mechanism exists. There is very limited infrastructure to collect and link biological samples from critically ill patients nationally. Comprehensive international clinical data sets may inform future Canadian initiatives. CONCLUSION Clinical and biological data collection among critically ill patients in Canada is not sufficiently coordinated, and lags behind other jurisdictions. An integrated and inclusive critical care data platform is a key clinical and scientific priority in Canada.

Abstract
Background: Low tidal volume ventilation (LTVV) strategy improves outcomes; however, despite recommended by guidelines, adherence to this practice is not high. Methods: Tidal volume for mechanically ventilated patients were recorded for each 12-hour shift, day and night shifts for consecutive 101 patients. Adherence was determined by comparing these tidal volumes to standard low tidal volumes of 6 ml/kg of ideal body weight. Adherence rates were calculated and adherence rates of daytime shifts were compared to those of night time shifts. Adherence rates for weekday shifts were compared with those of weekend shifts. Clinical variables were recorded to analyze predictors of adherence pattern. Results: The sample size was 101 patients with 870 patient-ventilator days with 1734 patient ventilator shifts. Shift adherence was only 47.5%. There was no significant difference between day and night shifts or weekday and weekend shifts. Stepwise multiple regression analysis shows that age, gender, body mass index (BMI), and partial pressure of carbon dioxide (PCO2) have significant correlation with adherence to LTVV practice. Conclusion: The study found that adherence to lung protective low tidal volume mechanical ventilation practice is low. Practice adherence is not different over weekend or night shifts. Age, gender, BMI, and PCO2 have significant correlation with adherence to LTVV practice.

Abstract
Acute respiratory distress syndrome (ARDS) is a devastating clinical syndrome with a considerable case fatality rate (∼30%-40%). Health disparities exist with African descent (AD) subjects exhibiting greater mortality than European descent (ED) individuals. Myosin light chain kinase is encoded by MYLK, whose genetic variants are implicated in ARDS pathogenesis and may influence ARDS mortality. As baseline population-specific epigenetic changes, that is, cytosine modifications, have been observed between AD and ED individuals, epigenetic variations in MYLK may provide insights into ARDS disparities. We compared methylation levels of MYLK cytosine-guanine dinucleotides (CpGs) between ARDS patients and intensive care unit (ICU) controls overall and by ethnicity in a nested case-control study of 39 ARDS cases and 75 non-ARDS ICU controls. Two MYLK CpG sites (cg03892735 and cg23344121) were differentially modified between ARDS subjects and controls (P < 0.05; q < 0.25) in a logistic regression model, where no effect modification by ethnicity or age was found. One CpG site was associated with ARDS in patients aged <58 years, cg19611163 (intron 19, 20). Two CpG sites were associated with ARDS in EDs only, gene body CpG (cg01894985, intron 2, 3) and CpG (cg16212219, intron 31, 32), with higher modification levels exhibited in ARDS subjects than controls. Cis-acting modified cytosine quantitative trait loci (mQTL) were identified using linear regression between local genetic variants and modification levels for 2 ARDS-associated CpGs (cg23344121 and cg16212219). In summary, these ARDS-associated MYLK CpGs with effect modification by ethnicity and local mQTL suggest that MYLK epigenetic variation and local genetic background may contribute to health disparities observed in ARDS.

Abstract
Objective: The current study aims to explore the factors associated with outcome among patients with severe sepsis and septic shock admitted to the intensive care unit, Northwest General Hospital and Research Centre, Peshawar, Pakistan. Methods: A prospective observational study was carried out at intensive care unit of our hospital from February 2014 to October 2015. Data was collected using a structured format and statistical analysis was done using SPSS version 20®. Regression model was applied to identify the factors contributing to the outcome of severe sepsis and septic shock. P-value less than 0.05 was considered statistically significant. Results: Majority of the patients meeting the criteria of this study were male 147 (54.9%) with a mean age of 54.8. The most common source of sepsis was lung infections (42.2%) followed by urinary tract infections (18.7%), soft tissue infections (6.3%) abdominal infections (6%) and in 6.3% patients the source remained unknown. Further analysis has revealed that increase in number of days of hospitalization was observed to be slightly associated with the outcome of the treatment (1.086 [1.002 – 1.178], 0.046). Moreover, the risk of mortality was the higher among the patients with septic shock 22.161[10.055 – 48.840], and having respiratory, kidney and central nervous system complications. Overall it is seen that septic shock alone was found responsible to cause death among 32.0% of the patients (Model 1: R2 0.32, p=0.000), and upon involvement of the organ complications the risk of mortality was observed to 42.0%. Conclusion: Chances of recovery were poor among the patients with septic shock. Moreover, those patients having respiratory and urinary tract infection are least likely to survive.

J Crit Care 2009; 25:176.e7-13. [PMID: 19592208 DOI: 10.1016/j.jcrc.2009.05.002] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2008] [Revised: 04/21/2009] [Accepted: 05/09/2009] [Indexed: 10/20/2022]
Abstract
OBJECTIVES The aim of this study was to determine whether cytokine expression (interleukin [IL]-1beta, IL-6, IL-8, IL-10, and tumor necrosis factor [TNF]-alpha), C-reactive protein, and endotoxins on the first day of intensive care unit (ICU) admission are associated with hospital mortality in severe community-acquired pneumonia (CAP). DESIGN This was a prospective study with bronchoalveolar lavage (BAL) and blood sampling. SETTING This study was carried out in a 44-bed medical ICU of a 1700-bed university hospital. PATIENTS Participants included 112 mechanically ventilated patients with severe CAP. INTERVENTIONS Serum and BAL fluid IL-1beta, IL-6, IL-8, IL-10, TNF-alpha, C-reactive protein, and endotoxins on the first day of ICU admission were obtained. MEASUREMENTS AND MAIN RESULTS The concentrations of TNF-alpha in BALF and IL-6, IL-8, IL-10, and TNF-alpha in serum were higher in nonsurvivors than in survivor patients with CAP. Of these 112 patients with severe CAP (39%), 44 developed acute respiratory distress syndrome (ARDS); these patients seemed to have higher serum IL-6, IL-8, and IL-10 levels than did the non-ARDS group. Furthermore, in the ARDS population, we found that the endotoxin levels in the BAL fluid were higher in the survival than in the nonsurvival group and BAL fluid concentrations of IL-6, IL-8, and IL-1beta and sera levels of IL-6 and IL-10 were lower in the survival than in the nonsurvival group, and they were associated with a high negative predictive value. CONCLUSIONS Serum and BAL fluid levels of the studied cytokines on admission may provide valuable prognostic information for patients with severe CAP.
