The Joseph Caprini and then updated on 2005

The most
common disease in the worldwide that increases mortality and morbidity and
decreases patients’ quality of life is venous thromboembolism (VTE), which
includes pulmonary embolism (PE) and deep venous thrombosis (DVT) 1. In US, there
is a high incidence of DVT and PE cases and patients’ death result from
one-third of VTE cases yearly 2. VTE prophylaxis is recommended in
hospitalized patients to reduce incidence of VTE, the problem is it underused
among half of these patients in many countries 3–6. VTE risk assessment
models (RAMs) are used to assess postsurgical patients’ risk factors and
prophylactic therapies according to their weighted risk scores by summed them
then assign the risk level 7.

RAMs have
two methods, either individual risk assessment or group risk assessment. The
data and studies showed that individual risk assessment is more effective and
concise 8–11. There are many individual VTE RAMs have been evaluated and
developed, the most common models are adapted by Caprini, Cohen, Kucher, etc 8–12.

Caprini risk
assessment model is a combination of clinical experience with recent published
data and established in early 1990s by Joseph Caprini and then updated on 2005
with new version. This new version is most common used and validated in
worldwide for postsurgical patients to assess their risk prediction 13–16.  In addition, it can provide appropriate
prophylaxis recommendations for each risk level and score which helps
physicians to increase their practical and convenient work. Caprini risk
assessment model is used in our institution (Ministry of National Guard-Health
Affairs – MNGHA) in postsurgical patients for almost a decay.   However, as far as we know, it has not
been validated among hospitalized elective surgical
patients in Saudi populations and in MNGHA

The specific objectives of this
study are to: (1) preliminarily assess the validity
of Caprini risk assessment model among hospitalized elective surgical patients
in Saudi population, and (2) explore the link between
individual patient risk assigned by the Caprini model and the recurrence of VTE
over the 12-month follow-up period after patients discharge.
