Barriers to Antiplatelet and Statin Adherence Following Major Vascular Intervention.

BACKGROUND: Antiplatelets and statins therapies are associated with improved cardiovascular outcomes following major vascular intervention. Many vascular surgery institutions are reporting improved prescribing rates for aspirin (ASA), P2Y12 antagonists, and statins. Nevertheless, there remains limited publication describing rates and patient-perceived barriers for postoperative adherence. The purpose of this study is to investigate patient nonadherence to antiplatelet and statin therapies following major vascular intervention. METHODS: A retrospective review of patients who underwent major vascular intervention at a single academic center was performed. The prescribing rates of ASA, P2Y12 antagonists, and statins were reviewed. Postoperative adherence, defined as consistent intake as prescribed, was evaluated at 1, 3, 6, 9, and 12 months using electronic documentation of both follow-up clinic appointments and phone call assessments, then corroborated with pharmacy fulfilment records. Patient-reported barriers to medication adherence were also examined. RESULTS: A total of 101 subjects underwent major vascular intervention between January 2020 and July 2020, 98% of whom were discharged on at least 1 antiplatelet or statin agent. Approximately 90% of patients were discharged with ASA, 32% with a P2Y12 antagonist, and 96% with a statin. All patients who maintained adherence up to 6 months continued to report adherence at 9 and 12 months. Consistent adherence at 12 months was documented in 76% of patients on ASA, 81% on P2Y12 antagonism therapy, and 73% on statins. New adverse drug reactions represented the most common barrier to achieving adherence (37% [n = 20]). Preoperative therapy with ASA, P2Y12 antagonists, and statins were all independently predictive of postoperative adherence to the same regimen (P ≤ 0.001). The female gender was also associated with higher rates of adherence to postoperative P2Y12 antagonism therapy (P ≤ 0.05). CONCLUSIONS: The current prescribing rates for antiplatelet and statin agents are promising, but postoperative nonadherence remains a multifaceted issue.

Use of high-frequency electrical stimulation in gastrocutaneous fistula closure: a case report.

BACKGROUND: Gastrocutaneous fistula is a rare complication following Roux-en-Y gastric bypass, a commonly performed bariatric surgery. While most ECFs respond to conservative management, some do not close despite adequate nutritional support, infection source control, and drainage management. As such, the chronicity of these difficult-to-treat wounds can be physically and economically costly to patients. CASE REPORT: A 53-year-old female with a history of Roux-en-Y gastric bypass developed a gastrocutaneous fistula secondary to a perforated gastrojejunal ulcer, requiring immediate surgical intervention. After being discharged from the hospital, 37 days of conservative management and NPWT did not reduce the size of the fistula tract. To help control the patient's chronic abdominal pain and increase the rate of wound healing, the patient underwent treatment with HFES (20 kHz) delivered using a handheld transcutaneous electrical nerve stimulator. This electrotherapy was found to reduce the majority of the patient's pain within the first treatment session. The patient's fistula also began to decrease in size within 1 week of initiating treatment. CONCLUSION: This case report details the successful closure of a gastrocutaneous fistula after administration of HFES 3 times a week over the course of 25 days. The mechanism of action of HFES and its role in the wound healing process are also discussed.

Impact of resuscitation adjuncts on postintubation hypotension in patients with isolated traumatic brain injury.

INTRODUCTION: Postintubation hypotension (PIH) is a risk factor of endotracheal intubation (ETI) after injury. For those with traumatic brain injury (TBI), one episode of hypotension can potentiate that injury. This study aimed to identify the resuscitation adjuncts that may decrease the incidence of PIH in this patient population. METHODS: This is a 4-year (2019-2022) prospective observational study at a level I trauma center. Adult (18 years or older) patients with isolated TBI requiring ETI in the trauma bay were included. Blood pressures were measured 15 minutes preintubation and postintubation. Primary outcome was PIH, defined as a decrease in systolic blood pressure of ≥20% from baseline or to ≤80 mm Hg, or any decrease in mean arterial pressure to ≤60 mm Hg. Multivariable logistic regression was performed to identify the associations of preintubation vasopressor, hypertonic saline (HTS), packed red blood cell, and crystalloids on PIH incidence. RESULTS: Of the 490 enrolled patients, 16% had mild (head AIS, ≤2), 35% had moderate (head AIS, 3-4), and 49% had severe TBI (head AIS, ≥5). The mean ± SD age was 42 ± 22 years, and 71% were male. The median ISS, head AIS, and Glasgow Coma Scale were 26 (19-38), 4 (3-5), and 6 (3-11), respectively. The mean ± SD systolic blood pressure 15 minutes preintubation and postintubation were 118 ± 46 and 106 ± 45, respectively. Before intubation, 31% received HTS; 10%, vasopressors; 20%, crystalloids; and 14%, at least 1 U of packed red blood cell (median, 2 [1-2] U). Overall, 304 patients (62%) developed PIH. On multivariable regression analysis, preintubation use of vasopressors and HTS was associated with significantly decreased odds of PIH independent of TBI severity, 0.310 (0.102-0.944, p = 0.039) and 0.393 (0.219-0.70, p = 0.002), respectively. CONCLUSION: Nearly two thirds of isolated TBI patients developed PIH. Preintubation vasopressors and HTS are associated with a decreased incidence of PIH. Such adjuncts should be considered prior to ETI in patients with suspected TBI. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.
