Derivation and validation of a risk factor model to identify medical inpatients at risk for venous thromboembolism.
This study’s objective was to compare multiple risk assessment models for hospitalized patients at high risk for venous thromboembolism (VTE). The authors developed a derivation cohort using 6 years of data from 12 hospitals to identify risk factors associated with developing VTE within 14 days of admission. The cohort included 155,026 patients with a 14-day VTE rate of 0.68%. The final multivariable model contained 13 risk factors and good calibration, and performance was evaluated using the C-statistic. The temporal validation cohort had 53,210 patients with a VTE rate of 0.64% and the external cohort had 23,413 patients and a rate of 0.49%. The Cleveland Clinic Model (CCM) outperformed both the Padua and IMPROVE models in the temporal cohort. In the external cohort the CCM C-statistic was similar to Padua and outperformed IMPROVE.

Trends in venous thromboembolism anticoagulation in patients hospitalized with COVID-19.
This study’s objective was to characterize frequency, variation across hospitals, and change over time in VTE prophylaxis and treatment-dose anticoagulation in patients hospitalized for COVID-19, as well as the association of anticoagulation strategies with in-hospital and 60-day mortality. This cohort study used adults hospitalized with COVID-19 from 30 pseudorandom hospitals in Michigan from March 7, 2020, to June 17, 2020. Main outcomes measured were the effect of nonadherence and anticoagulation strategies on in-hospital and 60-day mortality. Of a total 1351 patients with COVID-19 with a median age of 64 years, 47.7% women and 48.9% Black, only 18 (1.3%) had a confirmed VTE, and 219 (16.2%) received treatment-dose anticoagulation. Use of treatment-dose anticoagulation without imaging ranged from 0% to 29% across hospitals and increased over time. Of 1127 patients who ever received anticoagulation, 392 missed 2 or more days of prophylaxis. Missed prophylaxis varied from 11% to 61% across hospitals and decreased markedly over time. VTE nonadherence was associated with higher 60-day (adjusted hazard ratio [aHR], 1.31) but not in-hospital mortality (aHR, 0.97). Receiving any dose of anticoagulation (vs no anticoagulation) was associated with lower in-hospital mortality (only prophylactic dose: aHR, 0.36; any treatment dose: aHR, 0.38). However, only the prophylactic dose of anticoagulation remained associated with lower mortality at 60 days (prophylactic dose: aHR, 0.71; treatment dose: aHR, 0.92).

Prophylactic anticoagulation for preterm premature rupture of membranes: a decision analysis.
The objective of this study was to determine the optimal modality for venous thromboembolism prophylaxis during hospitalization for preterm premature rupture of membranes using a decision analysis model. The investigators concluded that their results did not support the routine use of prophylactic anticoagulation in women admitted to the hospital for preterm premature rupture of membranes.

Using electronic health record system triggers to target delivery of a patient-centered intervention to improve venous thromboembolism prevention for hospitalized patients: is there a differential effect by race?
Venous thromboembolism (VTE) is a leading cause of preventable harm, and disparities observed in prevention practices. In this study, the investigators examined the impact of a patient-centered VTE education bundle on the non-administration of preventive prophylaxis by race. The investigators found that the patient education materials, developed collaboratively with a diverse group of patients, improved patient's understanding and the importance of VTE prevention through prophylaxis.

Barriers to providing VTE chemoprophylaxis to hospitalized patients: a nursing-focused qualitative evaluation.
This study analyzed barriers for administration of VTE chemoprophylaxis to hospitalized patients from nurses. Researchers conducted 14 focus group interviews with nurses from five inpatient units to assess their perceptions of barriers to administration of VTE chemoprophylaxis. Barriers included nurses’ misconceptions that patients did not require chemoprophylaxis, their uncertainty when counseling patients on the importance of chemoprophylaxis, and a lack of comparative data regarding specific refusal rates.
