Examining patient comprehension of emergency department discharge instructions: Who says they understand when they do not?
Patient comprehension of emergency department (ED) discharge instructions is important for ensuring that patients understand their diagnosis, recommendations for treatment, appropriate follow-up, and reasons to return. However, many patients may not fully understand their instructions. Furthermore, some patients may state they understand their instructions even when they do not. ⋯ However, among female patients and patients with less than 4 years of college, there was significant positive correlation between self-report and physician evaluation of comprehension (ρ = 0.326, p = 0.04 and ρ = 0.344, p = 0.04, respectively), whereas there was no correlation for male patients and those with more than 16 years of education (ρ = 0.008, p = 0.9, ρ = -0.041, p = 0.84, respectively). Patients' perception of their understanding may not be accurate, especially among men, and those with greater than college education. Identifying which patients say they understand their discharge instructions, but may actually have poor comprehension could help focus future interventions on improving comprehension.

Renal dysfunction (RD) and venous congestion are related and common in heart failure (HF). Studies suggest that venous congestion may be the primary driver of RD in HF. In this study, we sought to investigate retrospectively the relationship between common measures of renal function with caval congestion and mortality among outpatients with HF and RD. ⋯ In a multiple logistic regression model, BUN/Cr > 25.5 (adjusted OR 2.98, p 0.015) and eGFR ≤ 45.8 (adjusted OR 5.38, p 0.002) identify patients at risk for caval congestion; a BUN/Cr > 23.7 was the best predictor of impaired collapsibility (adjusted OR 4.41, p 0.001). a BUN/Cr > 25.5 (HR 2.19, 95 % CI 1.21-3.94, p < 0.001) and NYHA class 3 (HR 2.91, 95 % CI 1.60-5.31, p < 0.0005) were independent risk factors associated with all-cause death during a median follow-up of 31 months. In outpatients with HF and RD, a higher BUN/Cr and lower eGFR are reliable renal biomarkers for caval congestion. The BUN/Cr is associated with long-term mortality and may help to stratify HF severity.

Self-administered adrenaline through an auto-injector is the main out-of-hospital treatment for anaphylaxis, and patients should be trained to promptly and correctly use the device. The aim of the study was to verify the proper use of the device and the correct drug administration, and to identify possible misuse by patients. In seven Italian Allergy clinics, patients who were previously provided with self-injectable adrenaline were recruited at the follow-up visit required for the renewal of their prescription. ⋯ The factor most closely related to proper use of the device was the education of the patient (p = 0.03), while age and the time from first prescription did not affect the ability to properly use the auto-injector. Even though accurate training is conducted, many patients are still unable to properly use the adrenaline auto-injector in case of anaphylaxis. Allergists should review the instructions provided to the patients every time a renewal of the auto-injector is prescribed.
