The Ability to Use Epinephrine Autoinjector in Patients Who Receive Prescription Immediately after Anaphylaxis.

BACKGROUND: Epinephrine autoinjector (EAI) is prescribed to prevent a fatal outcome in the case of a repeated anaphylactic reactions. We wanted to determine how adult patients who received their first prescription as part of an urgent treatment of an anaphylactic reaction or at their family physician were instructed on the use of EAI. METHODS: Nurses assessing patients' knowledge asked the patient to demonstrate how to use the EAI training device. Patients who performed the critical steps correctly in 1 min were labelled as competent. RESULTS: Forty-one patients (24% women, 46 ± 5 years) came for the allergy examination 116 ± 145 days after receiving a prescription for EAI. When prescribing, the doctor or nurse explained the instructions for the use of EAI to 63.4% patients, and 31.7 patients practiced the use of EAI using a training device. At the pharmacy, 22% received explanation and 7% also practiced using a training device. Fifty-four percent of patients were able to effectively administer EAI adrenaline within 1 min. Higher education level was associated with sufficient knowledge about the use of EAI (p = 0.026). At the time of the visit to the allergy specialist clinic, 61% of patients had EAI with them. The shelf life of EAI was known to 63% of patients. CONCLUSIONS: The activities to increase the prescription rate of EAI immediately after treatment of anaphylactic episode are not sufficient to prevent severe outcome after the repeated episodes of anaphylaxis as nearly a half of patients are not able to use EAI correctly.

Echocardiographic predictors of outcome in patients with chronic obstructive pulmonary disease.

BACKGROUND: We aimed to assess the relationship between echocardiographic characteristics and mortality in patients with chronic obstructive pulmonary disease (COPD). METHODS: We prospectively studied 154 patients (mean age 71 ± 10 years, 71% male) with COPD. All patients underwent transthoracic Doppler echocardiography within 48 hours of hospital admission. Primary endpoint was all-cause mortality during a median period of 22 months. RESULTS: Mildly elevated tricuspid regurgitation pressure and mitral E/e' ratio were the most commonly encountered echocardiographic abnormalities, observed in 60% and 56% of patients, respectively. In Kaplan-Meier analysis of survival, left atrial enlargement, E/e' ratio > 8, right atrial enlargement, right ventricular dilation, decreased tricuspid annular plane systolic excursion, decreased tricuspid annular systolic velocity, and elevated tricuspid regurgitation velocity were associated with all-cause mortality (p < 0.05 for all). In the Cox proportional hazards analysis, the mitral E/e' ratio (hazard ratio 1.048; 95% confidence interval 1.001-1.096) remained an independent echocardiographic predictor of survival after adjustment for age, COPD severity, and other baseline echocardiographic parameters. CONCLUSIONS: Among patients with COPD, an abnormal mitral E/e' ratio was an independent echocardiographic predictor of all-cause mortality. Echocardiographic evaluation of structural and functional cardiac abnormalities provides important prognostic information and should be used routinely in the assessment of patients with COPD. © 2016 Wiley Periodicals, Inc.

Prognostic implications of heart failure with preserved ejection fraction in patients with an exacerbation of chronic obstructive pulmonary disease.

Diagnosing heart failure with preserved ejection fraction (HFpEF) in patients with chronic obstructive pulmonary disease (COPD) is difficult due to overlapping pathophysiological pathways, risk factors and clinical presentations. We investigated the prevalence and prognostic implications of coexisting HFpEF in patients hospitalized for acute exacerbation of COPD. A total of 116 consecutive patients with an acute exacerbation of COPD were evaluated for HFpEF and followed for an average period of 22 ± 9 months for the occurrence of death from any cause. HFpEF was diagnosed in 22 (19 %) patients with COPD, who were older, and also had higher LV mass, left atrial size, and mitral E/Ea ratio than those without HFpEF (p < 0.05 for all comparisons). HFpEF was not independently associated with all-cause mortality [hazard ratio (HR) 1.07, 95 % confidence interval (CI) 0.44-2.62]. Global initiative for chronic Obstructive Lung Disease (GOLD) stage (IV vs. I-III, HR 2.37, CI 1.23-4.59) and N-terminal pro B-type natriuretic peptide (NT-proBNP) levels (HR 2.79, CI 1.12-6.98) were independent predictors of long-term survival. HFpEF is present in one-fifth of patients with exacerbated COPD. Non-invasively diagnosed HFpEF may not be an independent predictor of all-cause mortality. Elevated NT-proBNP levels and very severe COPD were independently associated with unfavorable overall survival.

Discharge coordinator intervention prevents hospitalizations in patients with COPD: a randomized controlled trial.

OBJECTIVES: To test whether coordination of discharge from hospital reduces hospitalizations in patients with chronic obstructive pulmonary disease (COPD). DESIGN: Randomized controlled clinical trial. SETTING: Specialized pulmonary hospital. PARTICIPANTS: Patients hospitalized for an acute exacerbation of COPD. INTERVENTION: Care as usual included routine patient education, supervised inhaler use, respiratory physiotherapy, and disease-related communication. The discharge coordinator intervention added assessment of patient situation and homecare needs. Patients and caregivers were actively involved and empowered in the discharge planning process, which was communicated with community medical professionals to provide continuity of care at home. MEASUREMENTS: The primary end-point of the study was the number of patients hospitalized because of worsening COPD. Key secondary end-points were time-to-COPD hospitalization, all-cause mortality, all-cause hospitalization, days alive and out of hospital, and health-related quality of life. RESULTS: Of 253 eligible patients (71 ± 9 years, 72% men, 87% GOLD III/IV), 118 were assigned to intervention and 135 to usual care. During a follow-up of 180 days, fewer patients receiving intervention were hospitalized for COPD (14% versus 31%, P = .002) or for any cause (31% versus 44%, P = .033). In time-to-event analysis, intervention was associated with lower rates of COPD hospitalizations (P = .001). A Cox model of proportional hazards, adjusted for sex, age, GOLD stage, heart failure, malignant disease, and long-term oxygen treatment, demonstrated that intervention reduced the risk of COPD hospitalization (hazard ratio 0.43, 95% confidence interval 0.24-0.77, P = .002). CONCLUSION: Among patients hospitalized for acute COPD exacerbation, discharge coordinator intervention reduced both COPD hospitalizations and all-cause hospitalizations.

Cardiac biomarkers predict outcome after hospitalisation for an acute exacerbation of chronic obstructive pulmonary disease.

PURPOSE: In chronic obstructive pulmonary disease (COPD), cardiovascular system is involved but less is known about role of specific cardiac biomarkers. We aimed to investigate associations between N-terminal pro B-type natriuretic peptide (NT-proBNP) and troponin T during hospitalisation with 6-month outcome. METHODS: This was a prospective study conducted in consecutive patients hospitalized for an acute exacerbation of COPD. On admission, and at discharge, NT-proBNP and troponin T were measured, and echocardiography was performed. Hospitalisations and mortality were recorded for 6 months after discharge. RESULTS: We included 127 patients (70 ± 10 years, 70% men, GOLD III/IV 87%). Left ventricular dysfunction was detected in 70 (55%) patients and diastolic dysfunction was the most common type (53 patients-42%). NT-proBNP and troponin T were elevated on admission in 60% and 36%, and at discharge in 28% and 19% of patients. During follow-up, 53 (42%) patients were hospitalized and 17 (13%) patients died. In Kaplan Meier analysis of survival curves, NT-proBNP on admission distinguished between deceased and surviving patients (p=0.011) whilst troponin T at discharge separated hospitalized and non-hospitalized patients (p=0.017). The adjusted Cox proportional hazard model confirmed these findings: discharge troponin T predicted hospitalisations (hazard ratio 2.89, 95% confidence interval 1.13-7.36) and admission NT-proBNP predicted mortality (hazard ratio 4.20, 95% confidence interval 1.07-14.01). CONCLUSIONS: Elevated NT-proBNP at discharge and troponin T on admission predict outcome in patients hospitalized for an acute exacerbation of COPD.

Effectiveness of discharge-coordinator intervention in patients with chronic obstructive pulmonary disease: study protocol of a randomized controlled clinical trial.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) follows a slowly progressive natural course that can be accelerated by acute exacerbations, which frequently trigger admissions to hospital. Specific healthcare professional profiles such as that of discharge coordinator have been successful in reducing numbers of hospitalizations and need for medical care in patients with various chronic diseases, but data for COPD are sparse and inconclusive. This study was conceived to test whether coordinated discharge and post-discharge care could reduce re-hospitalizations and use of resources in patients with COPD. METHODS/DESIGN: This ongoing single-center randomized controlled clinical trial, which began in November 2009, is enrolling COPD patients in Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages II IV, hospitalized because of acute exacerbation. Patients are randomized in a 1:1 fashion to the intervention group, which has care organized by a discharge coordinator, and a control group receiving the usual care. The primary endpoint of the study is the number of patients hospitalized because of worsening of COPD. Data are collected at baseline, at the time of hospital discharge, and at the following time-points after discharge: 48 hours, 7 10 days, 30 days, 90 days, and 180 days. DISCUSSION: In COPD patients requiring hospital admission, coordinated discharge appears a feasible option for improving patient and healthcare system-related outcomes. This study will provide evidence on the effectiveness of a discharge coordinator in patients hospitalized because of acute exacerbation of COPD and may give relevant guidance for implementation in clinical practice.

Mini nutritional assessment, body composition, and hospitalisations in patients with chronic obstructive pulmonary disease.

BACKGROUND: Limited information is available about Mini Nutritional Assessment (MNA) questionnaire in patients with chronic obstructive pulmonary disease (COPD). We have conceived this analysis to study the associations between MNA questionnaire, body composition, and rehospitalisations in patients with COPD. METHODS: This prospective study recruited control subjects and COPD patients for pulmonary function testing, nutritional assessment using MNA questionnaire, body composition measurement, and dyspnoea evaluation. We recorded hospitalisations during 6 months after discharge. RESULTS: Our sample included 22 healthy controls (71 ± 5 years, 59% men) and 108 COPD patients (71 ± 10 years, 75% men, 85% severe or very severe COPD). MNA score was significantly higher in control subjects than in COPD patients (27.0 ± 1.7 vs 21.2 ± 4.9, p < 0.001). MNA score decreased over GOLD stage (p = 0.02) and indicated malnutrition in 14% of patients, and further 55% were at risk of malnutrition. Body mass index but not body composition parameters was higher in control subjects when compared to COPD patients (29.1 ± 3.8 vs 27.0 ± 6.3, p = 0.041). A positive correlation between MNA score, body fat content (p = 0.001), and lean body mass (p < 0.001) was observed. During follow-up, 45 (41%) patients were rehospitalised. Malnourished patients had higher risk of rehospitalisation in univariate analysis (HR 2.62, 95%Cl 1.13-6.07), which was maintained in an adjusted model (HR 2.93, 95%CI 1.05-7.32). CONCLUSIONS: Malnutrition and risk of malnutrition was frequent, associated with lower body fat mass and lean body mass, and independently predicted hospitalisations at six months.
