Shortness of breath, or dyspnea, is the subjective experience of breathing discomfort and is a common, distressing, and debilitating symptom of lung cancer. There are no efficacious pharmacological treatments, but there is suggestive evidence that cognitive–behavioral treatments could relieve dyspnea. For this, understanding the psychological, behavioral, and social factors that may affect dyspnea severity is critical. To this end, patients with dyspnea were interviewed with questions framed by the cognitive–behavioral model—emphasizing thoughts, emotions, and behaviors as contributors and outcomes of dyspnea.

Two trained individuals conducted semi-structured interviews with lung cancer patients (N = 15) reporting current dyspnea. Interviews assessed patients’ cognitive–behavioral experiences with dyspnea. Study personnel used a grounded theory approach for qualitative analysis to code the interviews. Inter-rater reliability of codes was high (κ = 0.90).

Thoughts: Most common were patients’ catastrophic thoughts about their health and receiving enough oxygen when breathless. Emotions: Anxiety about dyspnea was the most common, followed by anger, sadness, and shame related to dyspnea. Behaviors: Patients rested and took deep breaths to relieve acute episodes of dyspnea. To reduce the likelihood of dyspnea, patients planned their daily activity or reduced their physical activity at the expense of engagement in hobbies and functional activities.

Patients identified cognitive–behavioral factors (thoughts, emotions, and behaviors) that coalesce with dyspnea. The data provide meaningful insights into potential cognitive–behavioral interventions that could target contributors to dyspnea.

Acute heart failure and chronic obstructive pulmonary disease (COPD) are sometimes difficult to differentiate in the emergency department (ED). We sought to determine the clinical impact of point-of-care ultrasonography (POCUS) in ED patients with suspected acute heart failure or COPD.

We conducted a prospectively collected cohort study with health records review with frequency matching at The Ottawa Hospital between March and September 2017. We included patients aged 50 and older with shortness of breath or cough from suspected acute heart failure or COPD. Our primary outcome was ED length of stay. Secondary outcomes were time to disposition decision, time to appropriate treatment, and the incidence of adverse events. We analyzed time-to-event outcomes using Kaplan-Meier analysis and Cox regression analysis with POCUS analyzed as a time-dependent variable, and the incidence of adverse events using logistic regression analyses.

There were 81 patients evaluated with lung POCUS and 243 matched patients who were not. Lung POCUS was not significantly associated with ED length of stay and time to disposition decision; however, patients evaluated with lung POCUS received disease-specific treatment faster compared with the non-POCUS group (adjusted hazard ratio, 1.50 [95% confidence interval, 1.05–2.15], a median time difference of 31 minutes). We found no significant differences in the incidence of adverse events.

In this study, use of lung POCUS resulted in no difference in ED length of stay and time to disposition decision, but was associated with faster administration of disease-specific treatments for elderly patients with suspected acute heart failure or COPD.

A multitude of life-threatening and nonlife-threatening processes cause chest pain and shortness of breath. Prehospital therapy for these patients may be lifesaving and includes pharmacologic interventions, as well as invasive procedures. Appropriate therapy depends on the diagnostic skills of the paramedic.

This study was undertaken to determine the accuracy of the paramedic diagnosis in patients transported with a chief complaint of pain or shortness of breath.

Multihospital, one large municipal hospital, one community hospital.

Prospective, cross-sectional study. Paramedics evaluated the patient and then completed a standard form indicating the diagnosis. The paramedic's and final emergency physician's diagnoses were compared to assess the accuracy of the paramedic diagnosis.

All patients who complained of chest pain or shortness of breath, transported to the study centers by the city of Denver paramedia, were eligible for the study. Ninety-nine of the 102 patients enrolled had complete records for analysis and were entered into the study.

Diagnostic concordance data were analyzed by organ system (e.g., cardiac, pulmonary, etc.) and for specific diagnoses using the kappa statistic and McNemar's chi-square analysis for discordant pairs. Using the kappa statistic, there was statistically significant concordance between the paramedic and emergency-physician diagnosis for cardiac (p = 0.0001; kappa value = 0.54) and pulmonary organ systems (p = 0.0001; kappa value = 0.61). Overall, for organ system diagnosis, the paramedics had an 82% accuracy (p = 0.05) rating. For specific cardiac and pulmonary diagnosis, paramedics had good concordance with emergency physicians.

Overall, paramedia have excellent diagnosis by organ system. They retained good agreement on specific cardiac diagnoses and pulmonary diagnosis.

The purpose of this study is to describe treatment of asthma in children by paramedics.

Retrospective review of an advanced life support (ALS) run reports over a one-year period.

Review of paramedic response to pediatric respiratory emergencies in an urban, primarily inner-city, prioritized, dual-response emergency medical services (EMS) system.

Patients < 19 years of age complaining of shortness of breath, paramedics, pediatric residents, and attending physicians.

The medical records of 383 patients were reviewed for demographic and medical information. The population was separated into an ALS treatment group (received ALS) and a NO-ALS group (evaluation and/or oxygen only). Sixty percent of the patients (n = 231) were classified into the ALS group; 89% received epinephrine. Sixty-six percent (n = 101) of the NO-ALS patients received evaluation only, and the remaining 34% (n = 51) were evaluated and received oxygen. The ALS patients were older and had significantly higher respiratory rates and accessory muscle use than did the NO-ALS patients. Relief was reported in 66 % of ALS patients. No adverse reactions were reported in the ALS group. Determining factors influencing ALS treatment included age, the use of medications at home, wheezing, accessory muscle use, respiratory rate, and presence or absence of upper respiratory infection (URI) symptoms.

This study demonstrates that asthma constitutes the majority of pediatric emergencies in the prehospital setting in this inner-city EMS system. The ALS treatment of pediatric asthma improves patient status. Factors which may influence paramedic judgment in treating asthma in children may be inappropriate. There is a critical need for further research in the prehospital treatment of pediatric asthma and in developing education interventions directed at the entire spectrum of prehospital care of pediatric emergencies.
