Standardized Documentation and Assessments for Polycythemia Vera: A Quality Improvement Initiative

Polycythemia vera (PV) is a myeloproliferative neoplasm (MPN) characterized by unregulated clonal expansion of myeloid cells that primarily manifests with elevated red blood cells. Transformation to more aggressive, and potentially fatal diagnoses such as myelofibrosis or acute myeloid leukemia is observed in 5-15% at 15 years. Compared to an age- and sex-matched general population, patients with PV have a 3- to 13-fold higher risk of arterial and venous thromboembolic (TE) complications, which are the leading causes of premature morbidity and mortality. Other manifestations include microvascular disturbances (blurry vision, problems with concentration, paresthesia, headaches, palpitations), pruritus, and erythromelalgia. These symptoms may present with severity that do not correspond to conventional risk and may be harbingers of disease progression. Palpable splenomegaly and associated weight loss is also present in a third of patients at the time of PV diagnosis.

Cytoreductive therapies are now available and recommended for low and high-risk PV patients. As an example, ropeginterferon alfa-2b is a Federal Drug Administration-approved and commercially available cytoreductive agent since 2021 that has been shown to improve symptoms, reduce thrombotic risk, reduce risk of disease transformation, and death. Consequently, it is important to be able to recognize who requires cytoreduction with a comprehensive assessment. Despite this, prior studies demonstrate assessments are rarely comprehensive, and despite the availability of cytoreductive therapies that may reduce risk of thromboses and improve symptoms and spleen, there are delays in adoption of such agents in the real-world clinical setting.

Numerous studies have shown that disease-specific standardized progress note templates can be an effective means to incorporate knowledge into a clinician's workflow and enhance care quality without increasing documentation burden. In addition, Mass General Brigham has recently implemented a pharmacist-led management of ropeginterferon alfa-2b for PV patients.

Hence, the researchers propose to assess the feasibility, acceptability, and appropriateness of a PV-specific, EMR-based progress note template, in addition to the pharmacist-led ropeginterferon alfa-2b titration pathway, for clinicians across the institution.
