Multicenter survey on emergency nurses’ perception of Numerical Rating Scale reliability at triage time in adult Emergency Department patients

Since pain perception is highly subjective and culturally mediated, its objective evaluation remains difficult. Nevertheless, pain measurement should ideally be a part of the assessment of patients in order to plan adequate pain relief. Several scales have been proposed for pain measurement, being the numerical rating scale (NRS) the most widely used, often at triage time. NRS have demonstrated acceptable reliability and validity, in post-operative medicine and in oncologic pain, but data in the Emergency Departments (EDs) are poor. The aim of this study is to evaluate the Emergency Nurses’ (ENs) perception about the reliability of NRS in the triage process. A questionnaire based on 11 items was designed and subsequently administered to a large number of ENs in several EDs in Northern and Central Italy. 301 questionnaires were filled out and returned. The majority declares using NRS scale to measure pain (item 2, mode = 4, mean = 3.8), and attributing priority code based on NRS value (item 3, mode = 4, mean = 3.4). In general, triage nurses believe that NRS is only indicative and that their judgement matters (item 4, mode = 4, mean = 3.2). The vast majority of triage nurses do believe that the patients will indicate a fake higher NRS value with the aim to get a more urgent code (item 5, mode = 5, mean = 4), while only a small minority expects that patients would underestimate their NRS for fear of penalizing more urgent patients. Very few believe that such scale underestimates the patients’ condition, while the majority is ambivalent about whether such scale overestimates it. In conclusion, NRS confirms to be a potentially valuable tool for pain evaluation at triage time, but many nurses express some doubts on its reliability, and will attribute the triage code mainly basing on their own judgement

No difference at two years between all inside transtibial technique and traditional transtibial technique in anterior cruciate ligament reconstruction

Background: one of the most recent technique is the “all inside” anterior cruciate ligament (ACL) reconstruction. One of the main characteristic ofthis procedure is the sparing of the tibial cortex. Furthermore, the all-inside technique requires only one tendon harvested. Purpose: the present study describes two year clinical outcomes of the all-inside method for ACL reconstruction, and compares them with clinical results of a group of patients treated with the traditional transtibial single-bundle ACL reconstruction technique using the semitendinosus and gracilis tendons (ST-G). Study design: pilot study, using historical controls. Methods: ACL reconstruction was performed on two groups of 20 patients each. The patients in one group underwent the all-inside transtibial technique with ST tendon alone. The second group underwent ACL reconstruction with the traditional transtibial single-bundle procedure using quadrupled ST-G tendons. Follow up at 24 months was undertaken using the IKDC, VAS pain score, Lysholm and Tegner scales. Results: the VAS pain score for the traditional ACL group was 84.6 ± 12.6; whereas the score for the all-inside group was 81.6 ± 13.1, with no statistically significant differences between the two groups. In the traditional ACL reconstruction group the Lysholm scale gave a “good results” for 7 patient (35%) and “excellent results” for 13 patients (65%) and the all-inside group gave “sufficient results” for 4 patients (20%), “good results” for 7 patients (35%) and “excellent results” for 9 patients (45%) (n.s.). The median of Tegner score was 6.5 (2-10) for the standard method group and 6 (1-9) for the all-inside group (n.s). The IKDC evaluated 50% of patients from the standard technique group as class A, and 45% as class B and 5% as class C. As regards patients of the all inside technique 55% were class A, 40% class B and, here too, just 5% scored as class C. No patients were classed as group D in each group. Conclusions: this study suggests that, in respect to return to sports and adequate articular function, there are no differences between the all-inside transtibial ACL reconstruction technique and the traditional transtibial ACL reconstruction using ST-G. The role of all-inside transtibial ACL reconstruction remains dubious. Level of evidence: III or Level C according with Oxford Center of EB

The concentration of high-sensitivity troponin I, galectin-3 and NT-proBNP substantially increase after a 60-km ultramarathon.

Background: The leading mechanisms responsible for the most prevalent and serious cardiac injuries include myocardiocyte stretch, myocardiocyte necrosis and cardiac fibrosis, which can now be reliably mirrored by measurement of natriuretic peptides, cardiospecific troponins and galectin-3, respectively. Although a large amount of knowledge has been gathered about the behavior and clinical significance of these biomarkers in patients with cardiac disorders, less information is available on their biology in paraphysiological conditions, including high-intensity endurance exercise. Methods: The study population consisted of 18 trained athletes, who performed a 60-km ultramarathon run. Blood was collected before the run (i.e., "baseline") and immediately after the end of the ultramarathon ("post-marathon") for measurement of serum high-sensitivity troponin I (TnI), NT-proBNP and galectin-3. Results: The concentration of all biomarkers measured in the post-marathon samples was remarkably increased as compared with the values obtained on baseline specimens. In particular, the median increase was 3.3 for TnI, 3.5 for NT-proBNP and 2.4 for galectin-3, respectively. The frequency of values exceeding the diagnostic threshold did not differ at baseline and after the ultramarathon for TnI (6% vs. 25%; p=0.15), instead was significantly increased for NT-proBNP (0% vs. 28%; p=0.016) and galectin-3 (0% vs. 67%; p<0.001). No significant correlation was found among the increase of any of the three biomarkers. Conclusions: The results of this study demonstrate that high-intensity endurance exercise is associated with biochemical abnormalities that may reflect adverse consequences on cardiac structure and biology

Combination of Platelet expression of PKCepsilon and cardiac troponin-I for early diagnosis of chest pain patients in the emergency department

A rapid differential diagnosis of the clinical conditions underlying chest pain is a relevant clinical issue. Specifically, a fast rule-in or -out of acute myocardial infarction (AMI) is mandatory to improve diagnostic outcome and cost-effectiveness of patient management. We demonstrated that Protein Kinase C (PKC) epsilon is selectively expressed by platelets from AMI patients, accounting for increased platelet activation. Thus, we hypothesized that PKCepsilon-expressing platelets may represent a pathophysiological marker of AMI that could be utilized in combination with troponin-I, the conventional marker of cardiac injury, to add diagnostic information in chest pain workup. In 94 chest pain patients consecutively admitted to Parma University Hospital, we tested the diagnostic performance of flow-cytometric detection of PKCepsilon expressing platelets in discriminating AMI vs. non-AMI conditions. We demonstrated that PKCepsilon-expressing platelets were significantly higher in patients with AMI. Flow cytometry detection of PKCepsilon-expressing platelets showed high sensitivity and specificity (87.5% and 84.4%, respectively) and good diagnostic accuracy (AUC: 0.875). The combination of PKCepsilon expressing platelets and cardiac troponin clearly discriminates patients with 100% and 0% of probability to be affected by AMI. Overall, we highlighted a dual marker strategy potentially useful for a rapid rule-in or -out of myocardial infarction in chest pain patients

Usefulness of suPAR in the risk stratification of patients with sepsis admitted to the emergency department

To investigate the role of suPAR in patients with sepsis admitted to the Emergency Department (ED). We performed multicentre prospective trial including patients admitted to the ED of three different Italian hospitals. Patients were studied upon admission on day 1, 2, 4 and 7. They were subdivided into two groups: sepsis (group 1) and severe sepsis or septic shock (group 2). The two groups were comparable for age, gender and CRP level on day 1. Patients with severe sepsis or septic shock displayed significantly higher baseline levels of suPAR, PCT and lactate. In both groups, suPAR decreased across the time (p&nbsp;&lt;&nbsp;0.0005). Group 1 was not different from group 2 (p&nbsp;=&nbsp;0.545) in mortality at 7&nbsp;days, while group 2 had higher mortality at 30&nbsp;days than group 1 (p&nbsp;=&nbsp;0.022). At the multivariate analysis, lactate1 (p&nbsp;=&nbsp;0.012) and age (p&nbsp;=&nbsp;0.019) were independent predictors of mortality at 7&nbsp;days, whereas suPAR1 (p&nbsp;=&nbsp;0.023) and age (p&nbsp;=&nbsp;0.032) were independent predictors of mortality at 30&nbsp;days. Lactate and suPAR resulted the most predictive biomarkers in the risk stratification of patients with suspected infection initially admitted to the ED, according to their role in predicting 7- and 30-day mortality, respectively
