RESUMEN
BACKGROUND: Despite antiviral agents that can cure the disease, many individuals with Hepatitis C Virus (HCV) remain untreated. Primary care clinicians can play an important role in HCV treatment but often feel they do not have the requisite skills. METHODS: We implemented a population-based improvement intervention over 10 months to support treatment of HCV in a primary care setting. The intervention included a decision-support tool, education for clinicians, enhanced interprofessional team supports, mentorship, and proactive patient outreach. We used process and outcome measures to understand the impact on the proportion of patients who initiated treatment and achieved Sustained Virologic Response (SVR). We used physician focus groups and pharmacist interviews to understand the context and mechanisms influencing the impact of the intervention. RESULTS: Between December 2018 and June 2020, the percentage of HCV RNA positive patients who started treatment rose from 66.0% (354/536) to 75.5% (401/531) with 92.5% (371/401) of those starting treatment achieving SVR. Qualitative findings highlighted that the intervention helped raise awareness and confidence among physicians for treating HCV in primary care. A collaborative team environment, education, mentorship, and a decision-support tool integrated into the electronic record were all enablers of success although patient psychosocial complexity remained a barrier to engagement in treatment. CONCLUSION: A multifaceted primary care improvement initiative increased clinician confidence and was associated with an increase in the proportion of HCV RNA positive patients who initiated curative treatment.

Tumor lysis syndrome (TLS) is a complication of malignancies with high tumor cell proliferation, tumor burden, and chemosensitivity. It manifests with the release of intracellular components and results in hyperkalemia, hyperphosphatemia, hypocalcemia, and hyperuricemia. These biochemical abnormalities may lead to serious complications such as renal failure, cardiac dysrhythmias, and death. Rasburicase, a recombinant urate oxidase enzyme, is a new agent indicated in the treatment or prophylaxis of hyperuricemia in pediatric patients with cancer who are at high risk for TLS. We reviewed the evidence for treatment with this agent compared with standard therapy with allopurinol. Rasburicase may be considered for use in patients with hyperuricemia at presentation and in patients at high risk for TLS that would otherwise result in a delay in chemotherapy. However, randomized controlled trials are required to establish the comparative efficacy of rasburicase in the adult population. Preliminary evidence suggests that single-dose or reduced-dose rasburicase may be effective in the prophylaxis and the treatment of hyperuricemia and TLS. However, to our knowledge, there is no evidence comparing clinically relevant outcomes such as acute renal failure or dialysis.

Approximately 2% to 4% of patients undergo urgent or emergency coronary artery bypass grafting (CABG) for complications of percutaneous coronary intervention (PCI) after treatment with glycoprotein (GP) IIb/IIIa inhibitors. The pharmacokinetic and pharmacodynamic properties of GP IIb/IIIa inhibitors play a large role in determining the safety of their use in the setting of urgent or emergency CABG procedures. Emergency or urgent CABG after treatment with the GP IIb/IIIa inhibitor, abciximab, may be associated with increased risk of hemorrhage and the requirement of platelet transfusions if surgery is performed within 12 h of abciximab discontinuation. Eptifibatide is associated with a similar risk compared with placebo, even when surgery is performed within 2 h of eptifibatide cessation. Limited data for tirofiban show that bleeding is not increased when compared with acetylsalicylic acid or heparin. Eptifibatide and tirofiban appear to have favourable safety profiles compared with abciximab in the setting of emergency or urgent CABG after failed PCI.
