This study was undertaken to determine, in a general practice setting, whether there is any difference in haemolysis obtained when using BD Vacutainer® Rapid Serum Tubes (BD RST) compared with using BD Vacutainer® SST™ II Advance Blood Collection Tubes (BD SSTII). Blood was collected from 353 patients requiring blood sampling who were attending 31 general practitioner practices in Belgium. For each patient, two BD SSTII tubes and two BD RST tubes were drawn in a randomized order. One of each pair of tubes was inverted five times, the other was not. Serum potassium concentration, serum LDH activity and haemolysis index were measured in each sample. There was no significant difference in measured potassium concentration according to tube type (P = 0.16). Measured LDH activities were 1.7% higher in serum collected into BD SSTII tubes compared to BD RST tubes (P = 0.02). When comp...

Patients presenting with chest pain have a 5% chance of experiencing a coronary event. These patients are at risk of mortality and should be recognized and referred to secondary care.

Owing to the risks of ventricular fibrillation and pulseless ventricular tachycardia, urgent transport should be organized under safe conditions, that is, with a defibrillator at hand.

A systematic review was conducted to determine the accuracy of 10 important signs and symptoms in selected and non-selected patients. Diagnostic meta-analysis. Using MEDLINE, CINAHL, EMBASE, tracing references, and by contacting experts, studies were sought out that described one of the 10 signs and symptoms on one or both conditions. Studies were excluded if they were not based on original data. Validity was assessed using QUADAS and all data were pooled using a random effects model. Sixteen of the 28 included studies were about patients who were non-selected. In this group, absence of chest-wall tenderness on palpation had a pooled sensitivity of 92% (95% confidence interval [CI] = 86 to 96) for acute myocardial infarction and 94% (95% CI = 91 to 96) for acute coronary syndrome. Oppressive pain followed with a pooled sensitivity of 60% (95% CI = 55 to 66) for acute myocardial infarction. Sweating had the highest pooled positive likelihood ratio (LR+), namely 2.92 (95% CI = 1.97 to 4.23) for acute myocardial infarction. The other pooled LR+ fluctuated between 1.05 and 1.49. Negative LRs (LR-) varied between 0.98 and 0.23. Absence of chest-wall tenderness on palpation had a LR- of 0.23 (95% CI = 0.18 to 0.29). Based on this meta-analysis it was not possible to define an important role for signs and symptoms in the diagnosis of acute myocardial infarction or acute coronary syndrome. Only chest-wall tenderness on palpation largely ruled out acute myocardial infarction or acute coronary syndrome in low-prevalence settings.

The aim of our study was to identify GPs' reasons for referring or not referring patients presenting with chest pain.

Little is known which signs and symptoms are important in general practice. With this qualitative study, we aimed to identify possible new important diagnostic variables. Semi-structured interviews with parents and physicians of children with a serious infection. We investigated all signs and symptoms that were related to or preceded the diagnosis. The analysis was done according to the grounded theory approach. Participants were recruited in general practice and at the hospital. 18 children who were hospitalised because of a serious infection were included. On average, parents and paediatricians were interviewed 3 days after admittance of the child to hospital, general practitioners between 5 and 8 days a...
