Functional decline in emergency department patients with dyspnea: a register-based cohort.

BACKGROUND: Functional decline is associated with frequent hospital admissions and elevated risk of death. Presumably, patients acutely admitted to hospital with dyspnea have a high risk of functional decline. OBJECTIVE: The aim of this study was to describe patient characteristics, hospital trajectory and use of physiotherapy services by dyspneic patients in an emergency department. The study also wanted to compare readmission and death among patients with and without a functional decline and to identify predictors of functional decline. METHODS: Data originated from a historic cohort of patients admitted to a Danish Emergency Department using prospectively collected electronic patient record data from a Business Intelligence Registry of the Central Denmark Region. The study included adult patients who were treated at the emergency department (ED) for dyspnea in 2015. The main outcome measures were readmission, death and functional decline. RESULTS: In total, 2048 dyspneic emergency treatments were registered. Within 30 days after discharge, 20% was readmitted and 3.9% had died. Patients with functional decline had a higher rate of 30-day readmission (31.2% vs. 19.1%, P < 0.001) and mortality (9.3% vs. 3.6%, P = 0.009) as well as mortality within 1 year (36.1% vs. 13.4%, P < 0.001). Predictors of functional decline were age ≥60 years and hospital stay ≥6 days. CONCLUSION: Patients suffering from acute dyspnea are seen at the ED at all hours. In total, one in five patients were readmitted and 3.9% died within 30 days. Patients with a functional decline at discharge seem to be particularly vulnerable.

Dyspnoea and self-management strategies in patients admitted to the emergency department: A study of patients' experiences.

AIMS AND OBJECTIVE: To explore patients' experiences of acute dyspnoea, physical functioning and perspectives on course of illness prior to admission to the emergency department. BACKGROUND: Many emergency admissions are considered unnecessary and avoidable. In this perspective, it seems relevant to gain insight into the patients' perspective on acute dyspnoea and the need for emergency admission. However, only few studies have investigated reasons for emergency admission from a patient perspective. DESIGN: A qualitative study was conducted with semi-structured interviews among six patients previously admitted to the emergency department due to dyspnoea. Data collection and analysis were carried out according to Kvale & Brinkmann using meaning condensation. FINDINGS: Dyspnoea was experienced as an unpleasant breathlessness in the form of pain or suffocation, which limited usual physical activities, negatively impacting on quality of life. Self-management strategies such as medication, breathing exercises, distraction from breathing, and mental and physical relaxation in general were used to avoid hospital admission. The chronically ill patients saw the following ways to alternate course of disease to avoid admissions to the emergency department: easier access to specialised emergency medical care, medical supplies in the patient's home and making existing physical exercise programmes more accessible and interesting. CONCLUSION AND RELEVANCE TO CLINICAL PRACTICE: It would be relevant to further investigate whether prehospital interventions may remedy acute dyspnoea among chronically ill patients, and whether such interventions are cost-effective.

Validity of the Talk Test as a Method to Estimate Ventilatory Threshold and Guide Exercise Intensity in Cardiac Patients.

PURPOSE: To determine the relationship between the Talk Test (TT) and ventilatory threshold (VT) in patients with cardiac disease and to compare the TT with exercise intensity guidelines. METHODS: Twenty cardiac patients, aged 65 ± 8.5 yr, performed 2 exercise tests with identical ramp protocols on a cycle ergometer on the same day. One test was a submaximal effort to assess exercise intensity using the TT. The other was a cardiopulmonary exercise test using breath-by-breath gas analysis to identify VT and cardiorespiratory fitness. RESULTS: Oxygen uptake and workload at the last positive stage (TTpos) was significantly lower than at VT. and workload at the equivocal stage (TTeq) and the first negative stage (TTneg) were not significantly different from VT, but limits of agreement (LoA) were wide. There was no significant difference in heart rate (HR) at TTpos and TTeq compared with VT, but HR at Tneg was significantly higher. The correlations between the TT and VT ranged from 0.37 to 0.60. Intensity at the different TT stages ranged from 58-77% of . All TT stages were within intensity guidelines of 40-80% of . CONCLUSION: Although no significant differences were found in and workload for TTeq and TTneg when compared with VT, LoA demonstrated wide ranges, suggesting poor individual correspondence. The different stages of the TT can be used as a practical method to guide exercise intensity in patients with cardiac disease.

The effects of various respiratory physiotherapies after lung resection: a systematic review.

Purpose: The purpose of this review was to investigate the effect of respiratory physiotherapy after lung resection on mortality, postoperative pulmonary complications (PPC), length of stay, lung volumes, and adverse events. Material and methods: Randomized or quasi-randomized controlled trials were searched in CENTRAL, PubMed, EMBASE, Cinahl, PEDro, and hand searching of related studies. Various respiratory physiotherapy interventions were compared to standard care, sham treatment, or no treatment. Two reviewers assessed eligibility and quality of studies using Cochrane guidelines. Meta-analyses were undertaken on subgroups of intervention. Results: Various types of positive pressure breathing, deep breathing exercises, and strength and aerobic exercises as a supplement to standard care did not show any significant effect over standard care in preventing mortality or PPC, reducing length of stay, or improving lung volumes. Conclusion: Prophylactic continuous positive airway pressure does not seem to affect rate of mortality and PPC, when compared with standard care embodying respiratory physiotherapy such as airway clearance techniques and assistance with early ambulation. However, further research is still needed to make a final conclusion. The effect of standard respiratory physiotherapy as a package is still unknown, and may or may not be effective in preventing PPC among patients undergoing lung resection.
