Introduction: Atherosclerotic peripheral artery disease (PAD) leads to a great burden of cardiovascular and limb-related morbidity and mortality in African Americans (AA) compared to White Americans. Medical center partnerships with churches may be an effective method to improve PAD awareness and detection in the AA community. Hypotheses: We hypothesized that implementing a medical educational program in partnership with churches would increase PAD familiarity and identify participants with undiagnosed PAD. Aims: To determine (1) PAD familiarity before and after a one-time educational intervention and (2) the prevalence of PAD in older, church-going Nashville residents. Methods: Using a community-engaged research (CER) model, we partnered with 5 churches to enroll participants ≥ 50 years of age. Participants were given a 16-point pre- and post-educational program assessment to determine baseline and post-intervention PAD knowledge. Pre- and post-intervention scores were compared using Wilcoxon signed-rank test. Ankle-brachial index (ABI) testing was used to screen for PAD (ABI < 0.9). Results: We enrolled 120 participants (mean age [SD]: 64.67 [8.33] years, 74% women, 80% AA). The prevalence of PAD was 10.83%. Pre-intervention PAD awareness was low (mean score (MS): 10.89 [4.24]) and improved significantly post-intervention in all participants (MS: 13.88 [2.76; p=2 x 10 -12 ). Participants without PAD (ABI ≥ 0.9-1.39) (MS: 10.81 [4.28] vs. 13.91 [2.79]; p= p=4 x 10 -11 ) and with indeterminate status (ABI>1.4) (MS [SD]: 10.00 [5.03] vs. 14.10 [1.73; p=0.01) showed significant improvement in PAD awareness pre vs post intervention. Participants with PAD (ABI <0.9) (MS: 12.15 [3.26] vs. 13.46 [3.26; p=0.40) did not have significant improvement in their awareness scores. Conclusions: The PRAISE study demonstrates an effective CER partnership with churches as a method to increase PAD awareness and early detection of PAD, specifically among AAs.

Abstract BACKGROUND Emergency department (ED) overuse is a costly and often neglected source of postdischarge resource utilization after spine surgery. Failing to investigate drivers of ED visits represents a missed opportunity to improve the value of care in spine patients. OBJECTIVE To identify the prevalence, drivers, and timing of ED visits following elective spine surgery. METHODS Patients undergoing elective spine surgery for degenerative disease at a major medical center were enrolled in a prospective longitudinal registry. Patient and surgery characteristics, and patient-reported outcomes were recorded at baseline and 3 mo after surgery, along with self-reported 90-d ED visits. A multivariable regression model was used to identify independent factors associated with 90-d ED visits. For a sample of patients presenting to our institution's ED, charts were reviewed to identify the reason and time to ED postdischarge. RESULTS Of 2762 patients, we found a 90-d ED visit rate of 9.4%. One-third of patients presented to our institution's ED and of these, 70% presented due to pain or medical concerns at 9 and 7 d postdischarge, respectively, with 60% presenting outside normal clinic hours. Independent risk factors for 90-d ED visits included younger age, preoperative opioid use, chronic obstructive pulmonary disorder, and more vertebral levels involved. CONCLUSION Nearly 10% of elective spine patients had 90-d ED visits not requiring readmission. Pain and medical concerns accounted for 70% of visits at our center, occurring within 10 d of discharge. This study provides the clinical details and a timeline necessary to guide individualized interventions to prevent unnecessary, costly ED visits after spine surgery.
