Retrospective chart review to be conducted at Methodist Richardson Medical Center (MRMC) in Richardson, TX. All adult patients hospitalized with COVID-19 on enoxaparin for DVT prophylaxis will be included. Collected data will be analyzed to determine the safety and effectiveness of the varying enoxaparin doses, and results will be presented at the American Society of Health-System Pharmacists Midyear conference in December 2022.
Retrospective chart review to be conducted at Methodist Richardson Medical Center (MRMC) in Richardson, TX. All adult patients hospitalized with COVID-19 on enoxaparin for DVT prophylaxis will be included. Collected data will be analyzed to determine the safety and effectiveness of the varying enoxaparin doses, and results will be presented at the American Society of Health-System Pharmacists Midyear conference in December 2022. EPIC will be queried for data for this medication use evaluation, including the patient's age, sex, weight/BMI, ICU status, maximum D-dimer level, enoxaparin dose received, development of DVT or PE, incidence and type of bleeding events, readmission status, and mortality. Other patient specific factors such as the CCI score, Padua score, and IMPROVE score will be calculated using online risk assessment tools. To calculate the CCI score, a search function will be used to analyze the patient's health information in order to determine their age, history of myocardial infarction, congestive heart failure, peripheral vascular disease, stroke or transient ischemic attack, dementia, chronic obstructive pulmonary disease, connective tissue disease, peptic ulcer disease, liver disease, diabetes mellitus, kidney function, cancer status, blood dyscrasias, and HIV status to estimate their 10-year probability of survival. To calculate the Padua score, each patient must be evaluated for cancer status, history of VTE, mobility status, history of thrombophilic conditions, recent trauma or surgery, age, heart and/or respiratory failure, acute myocardial infarction and/or respiratory failure status, acute infection and/or rheumatologic disorder, obesity, and ongoing hormonal treatment. If a patient scores a 4 or more, then pharmacologic prophylaxis would be indicated. Lastly, to calculate each patient's bleeding risk, the IMPROVE bleeding risk assessment will be used. For this tool, the patient's age, gender, renal function, liver function, platelet count, ICU status, the presence of a central venous catheter, active gastrointestinal ulcer, history of bleeding in the previous three months, presence of rheumatic disease, and active malignancy are needed to calculate the risk. If the patient scores a 7 or higher on the assessment, they are at an increased risk for bleeding.
