Differences in quality of care, mortality, suicidal behavior, and readmissions among migrants and Danish-born inpatients with major depressive disorder

BACKGROUND: The increasing global migration has made migrants’ health a pertinent topic. This article aimed to examine whether migrants were less likely than Danish-born residents to receive guideline recommended care when hospitalized for major depressive disorder (MDD) and potential differences in clinical outcomes, including all-cause mortality, suicidal behavior, and readmissions during 1-year follow-up after first-time admission. METHODS: A national cohort study was performed, including all adult MDD inpatients at mental care units in the period 2011–2017. Migrants and two migrant subgroups (non-Western and Western) were compared with Danish-born patients. Quality of care was examined using multivariable Poisson and linear regression models. Clinical outcomes were examined using Cox proportional hazards regression analysis. RESULTS: Migrant-status was associated with a non-significantly lower chance of receiving high-quality care (relative risk [RR] = 0.93, confidence interval [CI] 0.86:1.01) and lower readmission rates for depression (hazard rate ratio [HR] = 0.93, CI 0.86:1.01), and significantly higher all-cause mortality (HR = 1.55, CI 1.19:2.01) and lower all-cause readmission rate (HR = 0.88, CI 0.83:0.94). No clear association was found regarding suicidal behavior. While associations were comparable for migrant subgroups regarding readmission, the associations with low quality of care and of all-cause mortality appeared strongest among Western migrants. CONCLUSIONS: Among inpatients with MDD in a universal tax-financed healthcare system, being a migrant was associated with a potential lower quality of in-hospital care and worse clinical outcomes. These results warrant further investigation to clarify the underlying explanation for these inequalities and to develop and test interventions to ensure better quality of care and clinical outcomes for migrant patients

Composite measures of quality of health care:Evidence mapping of methodology and reporting

BACKGROUND: Quality indicators are used to quantify the quality of care. A large number of quality indicators makes assessment of overall quality difficult, time consuming and impractical. There is consequently an increasing interest for composite measures based on a combination of multiple indicators. OBJECTIVE: To examine the use of different approaches to construct composite measures of quality of care and to assess the use of methodological considerations and justifications. METHODS: We conducted a literature search on PubMed and EMBASE databases (latest update 1 December 2020). For each publication, we extracted information on the weighting and aggregation methodology that had been used to construct composite indicator(s). RESULTS: A total of 2711 publications were identified of which 145 were included after a screening process. Opportunity scoring with equal weights was the most used approach (86/145, 59%) followed by all-or-none scoring (48/145, 33%). Other approaches regarding aggregation or weighting of individual indicators were used in 32 publications (22%). The rationale for selecting a specific type of composite measure was reported in 36 publications (25%), whereas 22 papers (15%) addressed limitations regarding the composite measure. CONCLUSION: Opportunity scoring and all-or-none scoring are the most frequently used approaches when constructing composite measures of quality of care. The attention towards the rationale and limitations of the composite measures appears low. DISCUSSION: Considering the widespread use and the potential implications for decision-making of composite measures, a high level of transparency regarding the construction process of the composite and the functionality of the measures is crucial

Anemia and 90-day mortality in COPD patients requiring invasive mechanical ventilation

Lone Rasmussen1,2, Steffen Christensen1,2, Poul Lenler-Petersen2, Søren P Johnsen11Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, Denmark; 2Department of Anaesthesiology and Intensive Care, Silkeborg Hospital, Silkeborg, DenmarkBackground: There are data to suggest that anemia is associated with increased mortality in patients with chronic obstructive pulmonary disease (COPD). In contrast, critically ill patients with low hemoglobin levels (4.3–5.5 mmol/L, 7.0–9.0 g/dL) in general do not appear to have a worsened clinical outcome. The effects of anemia in critically ill patients with COPD remain to be clarified. We examined the association between anemia (hemoglobin < 7.4 mmol/L, <12.0 g/dL) and 90-day mortality in COPD patients with acute respiratory failure treated with invasive mechanical ventilation in a single-institution follow-up study.Method: We identified all COPD patients at our institution (n = 222) admitted for the first time to the intensive care unit (ICU) requiring invasive mechanical ventilation in 1994–2004. Data on patient characteristics (eg, hemoglobin, pH, blood transfusions, and Charlson Comorbidity Index), and mortality were obtained from population-based clinical and administrative registries and medical records. We used Cox’s regression analysis to estimate mortality rate ratios (MRR) in COPD patients with and without anemia.Results: A total of 42 (18%) COPD patients were anemic at time of initiating invasive mechanical ventilation. The overall 90-day mortality among anemic COPD patients was 57.1% versus 25% in nonanemic patients. The corresponding adjusted 90-day MRR was 2.6 (95% confidence interval 1.5–4.5). Restricting analyses to patients not treated with blood transfusions during their intensive care unit stay did not materially change the MRR.Conclusion: We found anemia to be associated with increased mortality among COPD patients with acute respiratory failure requiring invasive mechanical ventilation.Keywords: anemia, mortality, chronic obstructive pulmonary disease, intensive car

Using the C₂HEST score for predicting postoperative atrial fibrillation after cardiac surgery: A report from the Western Denmark Heart Registry, the Danish National Patient Registry, and the Danish National Prescription Registry

ObjectivesNew-onset postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery. A targeted approach is necessary for prophylactic handling of the complication. The authors tested the performance of the C2HEST score to predict POAF in patients undergoing cardiac surgery.DesignRegister-based cohort study.SettingThree cardiothoracic centers.ParticipantsAll adult patients undergoing cardiac surgery in Western Denmark between January 1, 2010, and December 31, 2018, were included. Data on patient comorbidities before surgery were obtained from the Western Denmark Heart Registry, the Danish National Patient Registry, and the Danish National Prescription Registry.InterventionsThe C2HEST score (C2: Coronary Artery Disease/Chronic Obstructive Pulmonary Disease [1 point each]; H: Hypertension; E: Elderly [Age ≥75, 2 points]; S: Systolic Heart Failure [2 points]; T: Thyroid disease [hyperthyroidism]) was calculated for each patient. The primary outcome was POAF within the primary hospital stay. The C2HEST score's discriminative ability was evaluated and compared with an age-stratified version (mC2HEST) as well as 2 validated clinical risk models (CHADS2 and CHA2DS2-VASc).Measurements and main resultsAmong the 14,279 patients included, 4,298 (30.1%) developed POAF. The C2HEST score's performance was not significantly better than the CHADS2 and CHA2DS2-VASc scores (area under the curve [AUC] 0.553 [95% confidence interval {CI} 0.543; 0.563] v 0.543 [95% CI 0.535; 0.552] and 0.565 [95% CI 0.555; 0.574], respectively). The age-modified (mC2HEST) score showed only modest improvement in the risk model, with an AUC of 0.580 (95% CI 0.570; 0.590).ConclusionThe discriminative ability of the C2HEST score, measured by the AUC, was limited in this population, and was not proven to be superior to the CHADS2, CHA2DS2-VASc, and mC2HEST scores in predicting POAF after cardiac surgery
