Disparities in follow-up care for ballistic and non-ballistic long bone lower extremity fractures.

OBJECTIVES: To describe differences in follow-up compliance and emergency department (ED) visits between ballistic and non-ballistic operative lower extremity fracture patients. DESIGN: Retrospective study. SETTING: Urban level 1 trauma center. PATIENTS/PARTICIPANTS: Patients age ≥18 years with ≥1 tibia or femur fractures treated with ORIF or intramedullary nailing (IMN) between September 1, 2013 and August 31, 2015. MAIN OUTCOME MEASURE: A compliance fraction calculated as ([number of attended follow-up visits] / [number of attended follow-up visits + number of missed follow-up visits]) and ED visits in the post-operative period. RESULTS: 612 patients were studied. Patients with ballistic lower extremity fractures had a younger mean age (30.8 years v. 41.6 years; p < 0.0001); a shorter length of stay (5.00 days v. 8.00 days; p < 0.0001); and were more likely to be male (92.6% v. 68%; p < 0.0001) and African-American (90.1% v. 63.1%; p < 0.0001) when compared to non-ballistic long bone injuries. Increased follow-up compliance (defined as a compliance fraction ≥0.75) was associated with having a non-ballistic fracture (OR 1.73, 1.13-2.64; p = 0.01), not having an ED visit (OR 2.08, 1.30-3.33; p = 0.002), and being female (OR 1.82, 1.27-2.61; p = 0.001). Increased ED utilization (≥ 1 ED visit) was associated with ballistic mechanism (OR 1.95, 1.20-3.16; p = 0.006), a low follow-up compliance fraction (OR 2.08, 1.30-3.33; p = 0.0019), homelessness (OR 3.91, 1.53-9.98; p = 0.006), and African-American race (OR 2.26, 1.26-4.05; p = 0.05). Scheduling a specific follow-up visit on the discharge summary did not predict higher compliance (OR 1.51, 0.98-2.33; p = 0.06). Conversely, the lack of a specific follow-up visit scheduled on the discharge summary did not predict ED utilization (OR 0.63, 0.34-1.17; p = 0.14). CONCLUSION: The results of this study demonstrate that increased utilization of the ED was associated with ballistic fractures, homelessness, decreased clinic compliance, and African American race. Furthermore, patients with non-ballistic injuries, women, and those without any ED visit were more likely to have higher outpatient clinic compliance.

A retrospective descriptive analysis of patient adherence to dabigatran at a large academic medical center.

BACKGROUND: Clinical trials evaluating the efficacy of dabigatran followed a very strict protocol, which included close monitoring and follow-up. Patients followed in this controlled environment had an average medication possession ratio (MPR) greater than 0.95. However, very few studies have evaluated patient adherence to dabigatran in a real-world setting. Other studies of chronic medications indicate patients are not reliably adherent to twice daily regimens. Adherence to therapy is particularly important for direct thrombin inhibitors because there may be a risk of increased thromboembolic events associated with poor adherence to these agents.  OBJECTIVE: To identify the MPR for patients prescribed dabigatran at a large academic medical center and affiliated clinics.  METHODS: This retrospective descriptive study evaluated the MPR for patients prescribed dabigatran between January 1, 2012, and December 31, 2012. Patients included in this study had to receive dabigatran for a minimum of 3 months, have a primary care physician or cardiologist at the medical center or affiliated clinics, and must not use a mail order pharmacy. Patient MPR was calculated based on prescriptions picked up from the patient. RESULTS: After screening 400 patients, 159 patients met eligibility criteria. The mean MPR for the patients in this study was 0.63. Overall, 43% of the patients had an MPR of less than 0.80, and the mean MPR for this subgroup was 0.39 ± 0.27; 57% of the study population had an MPR of 0.80 or higher, with a mean MPR of 0.94 ± 0.08. There was a significantly higher proportion of men (67.7%, P = 0.0112) and a larger number of "as needed medications" prescribed (1.73 vs. 0.86, P = 0.0039) in patients with an MPR less than 0.80. There were 5 patients hospitalized during the study period (3 for bleeding, 1 for confusion, and 1 death not related to dabigatran therapy).  CONCLUSIONS: The relatively low mean MPR seen in this study may indicate that there is a need for improved anticoagulation services and follow-up for patients taking dabigatran.
