Hematopoietic stem cell transplantation activity in Mexico during the COVID19 pandemic: on the way to recovery.

ABSTRACT

OBJECTIVE: To analyze the number of HSCTs performed in 2019 vs. 2020 and report the status of transplant centers (TCs) during and a year after the COVID-19 pandemic. METHODS: We performed a comprehensive cross-sectional nationwide study including active TCs interrogating HSCT activity from 2019 through September 2021. An electronic survey was sent to TCs and consisted of items regarding the number and characteristics of procedures performed and were compared yearly. Changes to their institutions' transplant policies and practices during the COVID19 pandemic were also documented. Fifty centers were invited to participate, 33 responded. RESULTS: Most TCs were part of the public health system (63.7%). Almost half are in the country's capital, Mexico City (45.5%). Most centers performed <10 procedures per year. The number of HSCTs decreased from 835 in 2019-505 in 2020 (p < .001), representing a 40% reduction in transplant activity. The monthly transplant rate in 2021 increased to 58.3, compared to 42 in 2020 and close to 69.5 in 2019 (p < .001). All types of HSCTs decreased excluding haploidentical transplants. All institutions treated patients with COVID19, and over two-thirds experienced some form of hospital reconversion. Transplant activity stopped completely in 23 TCs (70%) during the pandemic with a median closure duration of 9.9 months (range, 1-21). In 2021, 9.1% of TCs remained closed, all of them in the public setting. CONCLUSION(S) The limited transplant activity in Mexico decreased significantly during the pandemic but is recovering and nearly in pre-pandemic levels.
