Use of D-dimer and lower extremity Doppler ultrasound results to obviate the need for computerised tomographic pulmonary angiography.
We hypothesise that correct interpretation of other diagnostic tests could reduce the use of computerised tomographic pulmonary angiogram (CTPA) examinations in patients with suspected pulmonary embolism (PE). ⋯ In patients with suspected PE, correct interpretation of D-dimer and leg Doppler US tests may reduce the demand for CTPAs.

The journal impact factor is often used to judge the scientific quality of individual research articles and individual journals. Despite numerous reviews in the literature criticising such use, in some countries the impact factor has become an outcome measure for grant applications, job applications, promotions and bonuses. The aim of this review is to highlight the major issues involved with using the journal impact factor as a measure of research quality. ⋯ Research quality cannot be measured solely using the journal impact factor. The journal impact factor should be used with caution, and should not be the dominant or only factor determining research quality.
