Safety and efficacy of direct oral anticoagulants across body mass index groups in patients with venous thromboembolism: a retrospective cohort design.

Current literature on the safety and efficacy of direct oral anticoagulants (DOACs) in patients of extreme weights are limited, however, they are still being prescribed in these populations. The objective of this study is to describe the safety and efficacy of DOAC therapy in patients of extreme weights for the treatment of venous thromboembolism (VTE) using body mass index (BMI) groups. A multi-site, retrospective cohort design at four hospitals was performed. Patients who experienced an initial VTE between November 2012 and August 2017 and placed on a DOAC were included. Patients were defined as: extremely obese (EO) if BMI ≥ 40 kg/m2, obese if BMI 30-39.9 kg/m2, normal/overweight if BMI 18.5-29.9 kg/m2, and underweight if BMI < 18.5 kg/m2. The primary efficacy outcome of recurrent VTE and primary safety outcome of major bleeding (MB) within 12 months were compared between weights. Univariate statistical tests and multivariate logistic regression analyses were performed. Rates of recurrent VTE showed no significant differences (p = 0.58) across groups; 7.8% (11/142) EO, 4.7% (18/383) obese, 5.2% (27/517) normal/overweight, and 5.9% (1/17) underweight. Proportions of MB were overall significantly different (p = 0.026); 6.3% (9/142) EO, 10.4% (40/383) obese, 10.1% (52/517) normal/overweight, and 29.4% (5/17) underweight. EO and obese patients had similar odds of MB compared to normal/overweight (OR 0.61, 95% CI [0.29, 1.26] and OR 1.04, 95% CI [0.67, 1.61]). Underweight patients showed larger odds of MB compared to normal/overweight (OR 3.73, 95% CI [1.26, 11.0]). This study found that recurrence of VTE was not associated with BMI. However, the proportions of major bleeding were statistically different among the BMI categories.

Variations of pain medication use for patients with acute extremity pain in an emergency department: A quality improvement project.

OBJECTIVE: The opioid epidemic continues to take over 50,000 lives annually. At least 75 percent of patients present to an emergency department (ED) for pain. The objective of this study is to describe the characteristic(s) for receiving opioid, non-opioid, and combination analgesics in an ED for acute extremity pain. METHODS: A single-site, retrospective chart audit was conducted at a community-based teaching hospital. Patients ≥ 18 years old who were discharged from the ED with acute extremity pain and received at least one analgesic were included. Primary goal included determining characteristics associated with the prescribing of analgesics. Secondary goals included amount of pain score reduction, frequency of prescribing, and discharge prescription patterns among each group. Analyses consisted of univariate and multivariate general linear models analyses. RESULTS: There were 878 patients identified as having acute extremity pain between February and April 2019. A total of 335 patients met inclusion criteria and were separated into three groups: nonopioids (n = 200), opioids (n = 97), and combination analgesics (n = 38). The individual characteristics showing statistical differences (p < 0.05) between the groups were (1) an allergy to specific analgesics, (2) diastolic blood pressure > 90 mmHg, (3) heart rate > 100 bpm, (4) opioid use prior to ED admission, (5) prescriber level, and (6) discharge diagnosis. Multivariate analyses showed combination therapy (regardless of which two analgesics were administered) had a significant difference in mean pain score reduction compared to nonopioids (p < 0.05). CONCLUSION: There are patient, prescriber, and environment-specific characteristics that are associated with analgesic selection in an ED. Combination therapy had the greatest reduction in pain regardless of the two medications received.
