Transitions in health care settings for frequent and infrequent users of emergency departments: a population-based retrospective cohort study.

BACKGROUND: Efforts to reduce emergency department (ED) volumes often target frequent users. We examined transitions in care across ED, hospital, and community settings, and in-hospital death, for high system users (HSUs) compared to controls. METHODS: Population-based databases provided ED visits and hospitalizations in Alberta and Ontario, Canada. The retrospective cohort included the top 10% of all the ED users during 2015/2016 (termed HSUs) and a random sample of controls (4 per each HSU) from the bottom 90% per province. Rates of transitions among ED, hospitalization, community settings, and in-hospital mortality were adjusted for sociodemographic and ED variables in a multistate statistical model. RESULTS: There were 2,684,924 patients and 579,230 (21.6%) were HSUs. Patient characteristics associated with shorter community to ED transition times for HSUs included Alberta residence (ratio of hazard ratio [RHR] = 1.11, 95% confidence interval [CI] 1.11,1.12), living in areas in the lower income quintile (RHR = 1.06, 95%CI 1.06,1.06), and Ontario residents without a primary health care provider (RHR = 1.13, 95%CI 1.13,1.14). Once at the ED, characteristics associated with shorter ED to hospital transition times for HSUs included higher acuity (e.g., RHR = 1.70, 95% CI 1.61, 1.81 for emergent), and for many diagnoses including chest pain (RHR = 1.71, 95%CI 1.65,1.76) and gastrointestinal (RHR = 1.66, 95%CI 1.62,1.71). Once admitted to hospital, HSUs did not necessarily have longer stays except for conditions such as chest pain (RHR = 0.90, 95% CI 0.86, 0.95). HSUs had shorter times to death in the ED if they presented for cancer (RHR = 2.51), congestive heart failure (RHR = 1.93), myocardial infarction (RHR = 1.53), and stroke (RHR = 1.84), and shorter times to death in-hospital if they presented with cancer (RHR = 1.29). CONCLUSIONS: Differences between HSUs and controls in predictors of transitions among care settings were identified. Co-morbidities and limitations in access to primary care are associated with more rapid transitions from community to ED and hospital among HSUs. Interventions targeting these challenges may better serve patients across health systems.. TRIAL REGISTRATION: Not applicable.

Diabetes during pregnancy among Métis people in Alberta: a retrospective cohort study.

BACKGROUND: Diabetes in pregnancy is an important public health concern for Indigenous populations. We sought to evaluate the prevalence and outcomes of pre-existing and gestational diabetes among Métis pregnancies compared with other pregnancies in Alberta, Canada. METHODS: We conducted a retrospective cohort study using administrative health data from 2006 to 2016 and the Métis Nation of Alberta Identification Registry to compare the prevalence of pre-existing and gestational diabetes among all singleton Métis births with non-Métis births. We compared 10 maternal and neonatal outcomes using adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in multivariable analyses. RESULTS: The study population included 7902 Métis and 471 886 non-Métis births. The age-standardized prevalence of pre-existing diabetes was 1.7% (95% CI 1.4%-2.1%) for Métis and 1.1% (95% CI 1.1%-1.2%) for non-Métis pregnancies. For gestational diabetes, the age-standardized prevalence was 6.3% (95% CI 5.6%-6.9%) for Métis and 5.4% (95% CI 5.3%-5.4%) for non-Métis pregnancies. After adjusting for parity, maternal weight, age, smoking during pregnancy and material and social deprivation, Métis pregnancies had 1.72 times higher prevalence of preexisting diabetes (adjusted OR 1.72, 95% CI 1.15-2.56) and 1.30 times higher prevalence of gestational diabetes (adjusted OR 1.30, 95% CI 1.08-1.57) than non-Métis pregnancies. Métis pregnancies with pre-existing diabetes had nearly 3 times the odds of developing preeclampsia (adjusted OR 2.96, 95% CI 1.27-6.90), while those with gestational diabetes had 48% higher odds of large-for-gestational-age infants (adjusted OR 1.48, 95% CI 1.00-2.19). INTERPRETATION: Métis pregnancies have an increased prevalence of pre-existing and gestational diabetes than non-Métis pregnancies and an elevated risk of some perinatal outcomes. Interventions to tackle these health inequities should address both physiologic and cultural dimensions of health, informed by Métis perspectives.

Perinatal and early life factors and asthma control among preschoolers: a population-based retrospective cohort study.

BACKGROUND: Preventing poor childhood asthma control is crucial for short-term and long-term respiratory health. This study evaluated associations between perinatal and early-life factors and early childhood asthma control. METHODS: This retrospective study used administrative health data from mothers and children born 2010-2012 with a diagnosis of asthma before age 5 years, in Alberta, Canada. The outcome was asthma control within 2 years after diagnosis. Associations between perinatal and early-life factors and risk of partly and uncontrolled asthma were evaluated by multinomial logistic regression. RESULTS: Of 7206 preschoolers with asthma, 52% had controlled, 37% partly controlled and 12% uncontrolled asthma 2 years after diagnosis. Compared with controlled asthma, prenatal antibiotics (adjusted risk ratio (aRR): 1.19; 95% CI 1.06 to 1.33) and smoking (aRR: 1.18; 95% CI 1.02 to 1.37), C-section delivery (aRR: 1.11; 95% CI 1.00 to 1.25), summer birth (aRR: 1.16; 95% CI 1.00 to 1.34) and early-life hospitalisation for respiratory illness (aRR: 2.24; 95% CI 1.81 to 2.76) increased the risk of partly controlled asthma. Gestational diabetes (aRR: 1.41; 95% CI 1.06 to 1.87), C-section delivery (aRR: 1.18; 95% CI 1.00 to 1.39), antibiotics (aRR: 1.32; 95% CI 1.08 to 1.61) and hospitalisation for early-life respiratory illness (aRR: 1.65; 95% CI 1.19 to 2.27) were associated with uncontrolled asthma. CONCLUSION: Maternal perinatal and early-life factors including antibiotics in pregnancy and childhood, gestational diabetes, prenatal smoking, C-section and summertime birth, and hospitalisations for respiratory illness are associated with partly or uncontrolled childhood asthma. These results underline the significance of perinatal health and the lasting effects of early-life experiences on lung development and disease programming.

A systematic review and meta-analysis of the correlation between maternal and neonatal iron status and haematologic indices.

BACKGROUND: Iron deficiency (ID) is the leading single-nutrient deficiency in the world. Anaemia is a common outcome of ID that affects half of pregnancies worldwide with serious consequences for child development. Whether haematologic indices and biomarkers of iron status in pregnant women correlate with those of their neonates is unclear. This systematic review evaluated studies comparing haematologic and iron status indices in pregnant women and their newborns/neonates. METHODS: We searched MEDLINE, EMBASE, CINAHL, and Web of Science from database inception until March 2020 for primary studies comparing haematologic and iron status indices between women and their newborns up to 48 h after birth. We summarized the results descriptively and calculated pooled correlation coefficients in mothers and newborns/neonates using the Schmidt-Hunter method. The protocol was registered at PROSPERO International Prospective Register of Systematic Reviews (Registration number: CRD42018093094). FINDINGS: Sixty-five studies were included. Pooled correlation coefficients for biomarkers of iron status in mothers and newborns/neonates were 0.13 (ferritin), 0.42 (hepcidin), 0.30 (serum/plasma iron), 0.09 (transferrin), 0.20 (transferrin saturation), and 0.16 (total iron binding capacity). Pooled correlation coefficients for haematological indices in mothers and newborns/neonates were 0.15 (haemoglobin), 0.15 (haematocrit), 0.25 (mean cell/corpuscular haemoglobin), 0.22 (mean cell/corpuscular volume). INTERPRETATION: Maternal biomarkers of iron and haematologic status correlate poorly with those in newborns/neonates. These results underscore a need for alternative approaches to estimate foetal/neonatal iron status and haematological indices.

Development of a patient-centred, evidence-based and consensus-based discharge care bundle for patients with acute exacerbation of chronic obstructive pulmonary disease.

INTRODUCTION: Hospital and emergency department discharge for patients with chronic obstructive pulmonary disease (COPD) is often poorly organised. We developed a patient-centred, evidence-based and consensus-based discharge care bundle for patients with acute exacerbations of COPD. METHODS: A purposeful sample of clinicians and patients were invited to participate in a two-round Delphi study (July-November 2015). In round 1, participants rated on a seven-point Likert scale (1=not at all important; 7=extremely important) the importance of 29 unique COPD care actions. Round 2 comprised items selected from round 1 based on consensus (>80% endorsement for Likert values 5-7). A list of 18 care items from round 2 was discussed in a face-to-face nominal group meeting. RESULTS: Seven care items were included in the COPD discharge bundle based on clinician and patient input: (1) ensure adequate inhaler technique is demonstrated; (2) send discharge summary to family physician and arrange follow-up; (3) optimise and reconcile prescription of respiratory medications; (4) provide a written discharge management plan and assess patient's and caregiver's comprehension of discharge instructions; (5) refer to pulmonary rehabilitation; (6) screen for frailty and comorbidities; and (7) assess smoking status, provide counselling and refer to smoking cessation programme. CONCLUSION: We present a seven-item, patient-centred, evidence-based and consensus-based discharge bundle for patients with acute exacerbations of COPD. Alignment with clinical practice guidelines and feasibility of local adaptations of the bundle should be explored to facilitate wide applicability and evaluation of the effectiveness of the COPD discharge bundle.

Evaluation of risk of bias assessment of trials in systematic reviews of oral health interventions, 1991-2014: A methodology study.

BACKGROUND: The authors aimed to describe how often and by what means investigators assessed the risk of bias of clinical trials in systematic reviews of oral health interventions and to identify factors associated with risk of bias assessments. METHODS: The authors selected therapeutic oral health systematic reviews published from 1991 through 2014. They extracted data related to the tools used for risk of bias assessment of primary studies and data related to other review characteristics. They descriptively analyzed the data and used multivariate logistic regression. RESULTS: The authors identified 1,114 oral health systematic reviews (130 Cochrane reviews and 984 non-Cochrane reviews). The investigators of the primary studies assessed risk of bias in 61.4% of the reviews, and the risk of bias assessments occurred more often in Cochrane reviews than in non-Cochrane reviews (100% versus 56.3%; P < .001) and in reviews published after the dissemination of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.17-2.06). Compared with the investigators of reviews of public oral health interventions, investigators of reviews of oral surgery were less likely to assess risk of bias (OR, 0.41; 95% CI, 0.25-0.67). Furthermore, the investigators of systematic reviews published in dental journals were less likely to assess risk of bias of individual trials (OR, 0.28; 95% CI, 0.19-0.41) compared with the investigators of reviews published in nondental journals. CONCLUSIONS: The investigators of primary studies did not undertake risk of bias assessment in a considerable portion of non-Cochrane oral health systematic reviews. The investigators of reviews published in dental journals were less likely to assess risk of bias than the investigators of reviews published in nondental journals. The results of this study provide evidence of the need for improving the conduct and reporting of oral health systematic reviews with respect to risk of bias assessment. PRACTICAL IMPLICATIONS: Clinicians should determine to what extent the findings of a systematic review are valid on the basis of whether the investigators assessed and considered risk of bias during the interpretation of findings.

Incidence and prevalence of chronic obstructive pulmonary disease among aboriginal peoples in Alberta, Canada.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major respiratory disorder, largely caused by smoking that has been linked with large health inequalities worldwide. There are important gaps in our knowledge about how COPD affects Aboriginal peoples. This retrospective cohort study assessed the epidemiology of COPD in a cohort of Aboriginal peoples relative to a non-Aboriginal cohort. METHODS: We used linkage of administrative health databases in Alberta (Canada) from April 1, 2002 to March 31, 2010 to compare the annual prevalence, and the incidence rates of COPD between Aboriginal and non-Aboriginal cohorts aged 35 years and older. Poisson regression models adjusted the analysis for important sociodemographic factors. RESULTS: Compared to a non-Aboriginal cohort, prevalence estimates of COPD from 2002 to 2010 were 2.3 to 2.4 times greater among Registered First Nations peoples, followed by the Inuit (1.86 to 2.10 times higher) and the Métis (1.59 to 1.67 times higher). All Aboriginal peoples had significantly higher COPD incidence rates than the non-Aboriginal group (incidence rate ratio [IRR]: 2.1; 95% confidence interval [CI]: 1.97, 2.27). COPD incidence rates were higher in First Nation peoples (IRR: 2.37; 95% CI: 2.19, 2.56) followed by Inuit (IRR: 1.92; 95% CI: 1.64, 2.25) and Métis (IRR: 1.49; 95% CI: 1.32, 1.69) groups. CONCLUSIONS: We found a high burden of COPD among Aboriginal peoples living in Alberta; a province with the third largest Aboriginal population in Canada. Altogether, the three Aboriginal peoples groups have higher prevalence and incidence of COPD compared to a non-Aboriginal cohort. The condition affects the three Aboriginal groups differently; Registered First Nations and Inuit have the highest burden of COPD. Reasons for these differences should be further explored within a framework of social determinants of health to help designing interventions that effectively influence modifiable COPD risk factors in each of the Aboriginal groups.

Frequency, determinants and impact of overcrowding in emergency departments in Canada: a national survey.

Several reports have documented the prevalence and severity of emergency department (ED) overcrowding at specific hospitals or cities in Canada; however, no study has examined the issue at a national level. A 54-item, self-administered, postal and web-based questionnaire was distributed to 243 ED directors in Canada to collect data on the frequency, impact and factors associated with ED overcrowding. The survey was completed by 158 (65% response rate) ED directors, 62% of whom reported overcrowding as a major or severe problem during the past year. Directors attributed overcrowding to a variety of issues including a lack of admitting beds (85%), lack of acute care beds (74%) and the increased length of stay of admitted patients in the ED (63%). They perceived ED overcrowding to have a major impact on increasing stress among nurses (82%), ED wait times (79%) and the boarding of admitted patients in the ED while waiting for beds (67%). Overcrowding is not limited to large urban centres; nor is it limited to academic and teaching hospitals. The perspective of ED directors reinforces the need for further examination of effective policies and interventions to reduce ED overcrowding.

Factores asociados al intento de suicidio en la poblacion colombiana / Associated factors in suicide attempts in colombian people

Objetivos: describir y analizar el perfil epidemiológico y los factores asociados al intento de suicidio en una muestra de la población Colombiana. Diseño: análisis secundario de la base de datos de la Primera encuesta nacional de salud mental y consumo de sustancias psicoactivas. Muestra: 25.135 personas fueron encuestadas. Se escogieron 21.988 personas de ambos sexos con edades entre 16 y 60 años, a quienes se les aplicó la escala de Zung para ansiedad y depresión. Se midieron 240 variables independientes. Medida de desenlace principal: reporte de intentos de suicidio en el último año y en la vida. Resultados: la prevalencia para intentos de suicidio en el último año y a través de toda la vida fue de 1,2 por ciento (IC 95 por ciento: 1,06-1,34) y 4,25 por ciento (IC 95 por ciento: 4,25-4,81) respectivamente. Con la técnica de regresión logística para variables policótomas, los intentos de suicidio en el último año estaban asociados con: edades de 16 a 21 años OR = 2,5 (IC 95 por ciento 1,5-4,2), depresión grave OR = 11,8 (5,1-27,3), moderada OR = 5,3 (3,1-9,0) y leve OR = 3,6 (2,4-5,8), niveles moderados y graves de ansiedad OR = 3,4 (1,8-6,7). Se encontraron resultados similares cuando se consideraron los intentos de suicidio a lo largo de la vida. Conclusiones: el intento de suicidio en Colombia tiene una prevalencia similar a la de otros países, la población con mayor riesgo tiene entre 16 y 21 años, presenta depresión o ansiedad, consulta al médico por 'nervios', es objeto de abuso verbal (particularmente en las mujeres) o tiene diferentes valores morales a los de su familia

Calidad de vida: revisión de sus aspectos conceptuales

La confusión alrededor del término Calidad de Vida es muy amplia y diferentes autores han intentado aproximaciones al concepto a partir de perspectivas a veces diametralmente opuestas. El objetivo de este artículo es proporcionar un marco de referencia para comprender las distintas maneras de entender este concepto, para finalmente llegar al plenteamiento de un modelo de Calidad de Vida según es entendido en la actuialidad. A pesar de que muchas de sus diferencias están lejos de ser superadas, la netualeza multidimensional de un constructo derivado de este modelo abre un campo de investigación muy interesante que ofrece tanto a pacientes como a clínicos un camino común para evaluar la efectividad de los tratamientos. Cinco perspectivas diferentes han contribuido a la evolución del término: a) el punto de vista psicológico, b) el concepto de utilidad, c) el concepto centrado en la comunidad, d) el concepto de reintegración a la vida normal y e) el principio de la distancia
