Comparative Study Observational Study
Venipuncture Versus Peripheral Catheter: Do Infusions Alter Laboratory Results?
Our aim was to evaluate the equivalence between analytic parameters from blood samples obtained from a saline solution lock device used for the infusion of drugs and those from venipuncture. In our emergency department, patients bearing a saline solution lock device have blood extracted by venipuncture to avoid possible contamination of the sample. ⋯ Blood samples extracted from a peripheral catheter with or without drug infusions are valid for the analysis of hematology, biochemistry, and coagulation parameters but not for venous blood gases. Nurses should know the benefits of using an existing peripheral catheter for drawing blood samples for laboratory analysis even when infusing commonly used drugs. Emergency nurses should consider collecting blood specimens from a venous access device regardless of the type of drug infusions administered, because it is a safe, simple, and fast technique, which is time efficient when treating patients with limited venous access sites. This procedure reduces patient discomfort and the risk of complications related to venipunctures.

Providing a screening, brief intervention, and referral for treatment (SBIRT) may encourage patients to obtain provider follow-up for definitive evaluation and treatment of undiagnosed hypertension (HTN). The aims of this study were to determine characteristics of an intervention that would persuade patients to follow-up with a primary care physician for further blood pressure (BP) evaluation, and encourage ED clinicians to provide an SBIRT for patients with elevated BP with no known history of HTN. ⋯ An SBIRT-HTN could be developed to target patients with elevated BP during an ED visit. The intervention must be simple, easy to implement, and include automated processes to remind clinicians to deliver the intervention. The intervention should include a description of the complications of untreated HTN and an outpatient physician referral.

Vital signs are an important component of the nursing assessment and are used as early warning signs of changes in a patient's condition; however, little research has been conducted to determine how often vital signs are monitored in the emergency department. Additionally, it has not been determined what personal, social, and environmental factors affect the frequency of vital sign monitoring. The purpose of this study was to examine what factors may influence the time between recording vital signs in the emergency department. ⋯ These findings are clinically important because greater time between vital sign recordings can lead to errors of omission by not detecting changes in vital signs that could reveal changes in the patient's condition. The findings of this study provide direction for future research focusing on determining whether higher frequency of vital signs surveillance contributes to higher quality care and linking quality of care to missing vital signs/inadequate monitoring.
