Venous thromboembolism (VTE) manifesting as deep vein thrombosis (DVT) and pulmonary embolism (PE) remains a common vascular disease with high mortality and morbidity.  The aim of the study is to assess the prevalence of the risk and prpphylaxis among Medical and Surgical patients of Jose R. Reyes Memorial Medical Center from January 2014 to December 2014.


This is a cross-sectional study in all medical and surgical patients, ages 41 years old and above, admitted at Medical, Neurology, Surgical, Orthopedic, Urology, Obstetrics and Gynecological ward of Jose R. Reyes Memorial Medical Center from January 2014 to December 2014.  Charts were reviewed using the Thrombosis Risk Assessment Model by Caprini et al. and VTE risk level were determined based on the summation of all risk factor's score.  Prophylaxis used was also recorded if there is any.  Statistics were generated from these variables and frequencies and percentage were computed.


A total of 6,529 charts were reviewed from January 2014 to December 2014 from the 6 departments.  Majority of patients belong to the department of Internal Medicine comprising of 45.15% of cases.  Most of the charts gathered and reviewed were male patients except in Obstetrics and Gynecology section with an overall proportion of 61.72% for male and 38.31% for female.  Most patients belong to the 41-60 years of age, having 64.78% of the total population.  While the risk level varied from low, moderate, high and highest, with an overall of proportion of 4.27% , 9.87%, 35.20% and 49.46%, respectively.  Most common risk factors were patients confined to bed >72 hours (41.80%), stroke >1month (18.53%) and malignancy (18.50%).  The risk level varied from high to highest in between each department.  Out of 6529 patients at risk for VTE, only 4.25% (278 patients) received the ACCP recommended prophylaxis.


A total of 6529 patients were at risk for VTE and 84.66% belongs to the high to highest risk.  Among which, only 4.25% of the patients at risk received the ACCP recommended prophylaxis.  A large extract was not utilizing the effective prophylaxis with an overall proportion of 95.28%.  Low molecular weight heparin being the most commonly used prophylaxis with 1.62%.  This necessitates the need for increasing awareness regarding VTE risk assessment and implementation of appropriate prophylaxis in all at risk hospitalized patients.
