Role of Antiplatelet Therapy in Hemodialysis Arteriovenous Graft Secondary Patency Following Successful Percutaneous Thrombectomy.

PURPOSE: The purpose of this study was to elicit the relationship of antiplatelet therapy (AP) in maintaining arteriovenous graft (AVG) patency after successful percutaneous pharmacomechanical thrombectomy ("declot"). MATERIALS AND METHODS: This was an institutional review board-approved retrospective review of AVG declot procedures between July 2019 and August 2020. AVG characteristics, bleeding complications, anticoagulation and antiplatelet medication regimens, and thrombosis free survival were evaluated. Recurrent time-to-event analysis was performed using a Prentice-Williams-Peterson Gap time model was performed to evaluate AVG thrombosis free survival. RESULTS: A total of 109 declots were technically successful and performed in 63 individual patients. The majority of procedures were performed in upper arm grafts (71%, n = 45). Dual antiplatelet (DAPT) was prescribed after 52 declots (48%), single antiplatelet was prescribed after 36 declots (33%), and anticoagulation was prescribed after 31 declots (28%). Median thrombosis free survival was 37 days (range 1-412 days) in the no antiplatelet group, 84 days (range 1-427 days) in the single antiplatelet group, and 93 days (range 3-407 days) in the DAPT group. Anti-platelet medications trended towards protective of AVG thrombosis in multivariate analysis (hazard ratio 0.84, 95% confidence interval 0.60-1.19); however, this did not reach statistical significance (P = 0.33). A total of 4 major and 5 minor bleeding events occurred. CONCLUSION: The results of this study support further evaluation of AP therapy in preventing secondary rethrombosis of dialysis AVG.

MDHAQ/RAPID3 can provide a roadmap or agenda for all rheumatology visits when the entire MDHAQ is completed at all patient visits and reviewed by the doctor before the encounter.

The management of rheumatoid arthritis (RA) depends more on the patient history than most other chronic diseases. A patient questionnaire provides a uniform, quantitative, protocolized, "scientific" patient history, with documented prognostic significance for work disability and mortality in RA greater than radiographs and laboratory tests and capacity to distinguish active from control treatment in clinical trials and to monitor clinical care with equivalent or greater significance than joint counts or laboratory tests. Therefore, a "scientific" approach to care of a person with a rheumatic disease involves review of patient function, pain, global status, fatigue, RAPID3, review of systems, self-report joint count, and recent medical history on an MDHAQ before conversation with the patient. This practice may be viewed as analogous to a doctor reviewing blood pressure, hemoglobin A1c, viral load, or radiograph before meeting with a patient who has hypertension, diabetes, HIV, or a healing fracture to provide a roadmap or agenda for the visit. Some sites have implemented RAPID3 without the remainder of MDHAQ, a practice that is discouraged. The MDHAQ requires only 5 to 10 minutes of the patient's time and involves a single sheet of paper, which is needed for a simple RAPID3, or even a patient global estimate of status to score a DAS28 or CDAI. Completion of MDHAQ/RAPID3 by each patient at each visit in the infrastructure of care with review by the doctor helps prepare the patient for the visit, improves doctor-patient communication, saves time for the doctor, and provides a roadmap or agenda for the visit.
