Philadelphia-negative chronic myeloproliferative neoplasms (Ph-MPN) might be good candidates for virtual follow-up. In this study, we aimed to analyze the follow-up of patients with Ph-MPN in Spain during COVID-19, its effectiveness, and acceptance among patients. We present a multicenter retrospective study from 30 centers. Five hundred forty-one patients were included with a median age of 67 years (yr). With a median follow-up of 19 months, 4410 appointments were recorded. The median of visits per patient was 7 and median periodicity was 2.7 months; significantly more visits and a higher frequency of them were registered in myelofibrosis (MF) patients. 60.1% of visits were in-person, 39.5% were by telephone, and 0.3% were videocall visits, with a predominance of telephone visits for essential thrombocythemia (ET) and polycythemia vera (PV) patients over MF, as well as for younger patients (enCOVID-19Follow-upPatient satisfactionPh-MPNSpainTelemedicineHumansAgedPandemicsRetrospective StudiesPatient SatisfactionSpainCOVID-19SARS-CoV-2Myeloproliferative DisordersPolycythemia VeraPrimary MyelofibrosisThrombocythemia, EssentialPhiladelphia-negative chronic myeloproliferative neoplasm follow-up: when the phone rings.
