Patients in pain that refuse acetaminophen at triage To the Editor, It is usually perceived that pain is under-evaluated and undertreated in the emergency department (ED) [1]. Nevertheless recent efforts have contributed to significantly reducing pain [2]. This includes the implementation of procedures for early delivery of analgesics beginning with nurse triage [3,4]. However it is currently unknown whether emergency patients accept early delivery of acetaminophen by triage nurses. Therefore we studied the prevalence and the factors for analgesic refusal at triage. We held this prospective, observational study at our ED. All consenting consecutive adults presenting with pain could be included. The institutional review board for the protection of human subjects of our institution approved the study protocol procedures. All participants provided oral informed consent and non-opposition. Nurses routinely deliver acetaminophen at triage using the following computerized procedure: patients are offered orodispersible acetaminophen (1 g) if Normalized Rating Scale ≥3, arterial blood pressure ≥100 mm Hg and Glasgow Coma Scale at 15, and in the absence of jaundice, acetaminophen allergy, or acetaminophen intake in the previous 6 hours. Patients under legal constraint or unable to answer the questionnaire could not be enrolled. A dedicated patient advocate checks on the patients for 10 hours a day (8 AM–6 PM), 5 days a week. Participants answered a faceto-face standardized interview. The patient advocate used prefilled proforma to record baseline data, acceptance/refusal of analgesics at triage, reasons for refusal, nurses’ characteristics, and behavior for analgesic delivery. Data were entered into SPPS (SPSS, Chicago, IL) [5]. Bivariate analysis was conducted to determine the association between each candidate predictor and refusal. All candidate variables with a bivariate P b 0.15 were entered into a multiple regression model. In the final model, the R2 (range of 0–1) was used as a measure of the power of the combined factors in predicting analgesic refusal. For the study period (19th of May to 2nd of August, 2011, 8 AM6 PM), 539 patients were observed. Among these, 336 (62%) accepted acetaminophen delivery at triage and 203 (38%) refused the treatment. Reasons for refusal are reported in Table. Most patients that refused analgesics at triage decided that pain was tolerable without analgesics. None of the patients were reluctant to acetaminophen delivery by a nurse at triage. Table Reasons for refusal of acetaminophen delivery by a nurse at triage in 203 patients Reasons for refusal

Characteristics of patients who accepted or refused acetaminophen were similar for age, sex, and level of anxiety (data not shown). In a multivariate analysis, higher social status (20% vs 10%, P = .001), lower levels of triage priority (39% vs 28%, P = .039) and less intense pain (P b .0001) were associated with acetaminophen refusal. More interestingly, the way triage nurses proposed acetaminophen influenced patients’ acceptance; patients were more likely to accept analgesic intake when nurses’ proposal lasted more than 5 seconds (P = .012) and nurses used directive sentences to suggest taking acetaminophen (P b .0001). Here we report that (i) patients in pain often refuse acetaminophen at triage, (ii) refusal is often related to patients’ perception of pain intensity, and (iii) the way nurses propose acetaminophen impacts on patients’ acceptance. Current explanation for inadequate management of pain in the ED has been the staff structure, the staff training, and perception of patients' pain. The role of the patient must also been considered. Up to two-thirds or more of patients may refuse analgesics [6,7]. Since changing a patient’s behavior remains challenging, healthcare givers should adapt and imagine new approaches, including continuous multifaceted processes based on information [7]. ED caregivers are understandably reluctant to apply time-consuming procedures. In our study, acceptance to treatment was directly related to the nurses’ message. As an example, if nurses used brief and negative messages (“Won’t you take some acetaminophen?”), chances are that patients' acceptance of analgesics is very weak. On the other hand, if nurses took time for a positive suggestion (“I give you 1 gram of acetaminophen, it will decrease your pain and help you in waiting for doctor's visit”), patients were more likely to accept treatment. The language and the self-confidence of health care providers both impact patients’ acceptance of procedures and treatments [8]. Directive sentences may appear to be intrusive in our post-paternalism period where patients should finally make an informed decision. Healthcare providers should help patients make choices that may affect their pain while in the ED. Therefore “neo-paternalism” is a good option to assist decision-making in patients initially reluctant to analgesics at triage. We understand that some patients would be difficult to persuade, especially those who don't want to take medication, and those who believe that acetaminophen is not strong enough to relieve their pain. On the other hand, 53% thought that their pain was bearable and 20% worried that analgesics will impair physicians’ evaluation. We believe that imperative suggestion for acetaminophen intake may encourage them to fight off their pain. The ED staff can have a positive influence on whether or not the patient will accept acetaminophen. Even though patients' instinct is valuable, we believe that reinforcing the nurses' role to initially administer analgesics may help relief in the ED and should be tested in an impact study.

N-terminal prohormone of brain natriuretic peptide—how far can we extrapolate? To the Editor, We read the article by Velibey et al [1] with interest. Their result is consistent with various other studies done in the past, but long-term (4 years) survival prediction on hospital admission with a single plasma N-terminal prohormone of brain natriuretic peptide (NT-proBNP) level is a new and important finding. The mean value of NT-proBNP is significantly correlated with ejection fraction and the functional class (New York Heart Association Class) of heart failure [2]. The author had neither commented on the functional status of the patients nor on the etiology of acute shortness of breath at the time of admission. Testing the levels of natriuretic peptide particularly brain natriuretic peptide and NT-proBNP offers a strong diagnostic, therapeutic, and prognostic tool in heart failure. Quantitative estimation of NT-proBNP at the time of discharge appears to be a better predictor of the state of ventricles. It also shows whether optivolemic status has been reached with therapy or not. N-terminal prohormone of brain natriuretic peptide level of less than 4000 pg/mL suggests adequate therapy of heart failure and predicts a stable posthospital discharge, whereas NTproBNP level of more than 7000 pg/mL on discharge has an increased risk of cardiovascular illness [3]. Estimated NT-proBNP at the time of admission and discharge not only predicts the prognosis of the patient in a better way but also suggests effectiveness of in-hospital therapy of heart failure [4,5]. Therefore, this study does not throw light on effectiveness of in-hospital therapy. N-terminal prohormone of brain natriuretic peptide level not only predicts mortality in heart failure, but it is also a prognostic marker in various other conditions like severe sepsis and septic shock [6], cirrhosis of liver [7], pulmonary embolism [8], and cardioembolic stroke [9]. The list of exclusion criteria for this study does not include the aforementioned conditions, which should have been excluded. To conclude, plasma levels of natriuretic peptides are used in the diagnosis, treatment, and prognosis in multiple conditions, but its utility is not proven beyond doubt in conditions other than heart failure. Usefulness of natriuretic peptide is mainly to differentiate between cardiac and noncardiac cause of acute dyspnea in the

Image quality evaluation of a portable handheld ultrasound machine for the focused assessment with sonography for trauma examination☆ 1. Introduction Benefits of handheld ultrasound devices include ease of portability, 1,2 lower cost, 3,4 and potentially reduced examination time. 5 However, questions have been raised about the quality of images obtained on these devices. 4 We hypothesized that the overall image quality of the smaller handheld device would be inferior to that of a larger cart-mounted machine during the focused assessment with sonography for trauma (FAST) examination. For evaluation in this study, we compared the pocket-sized GE Vscan ☆ Funding for this study was provided by the University of Maryland Emergency Medicine Network.
