Hemato-oncology services and COVID-19 Pandemic: The experience of Kazakhstan

Abstract Objectives The COVID-19 pandemic in Kazakhstan disrupted numerous healthcare services, including those critical for hemato-oncology patients, due to the strained healthcare system. This study examines how the COVID-19 pandemic has affected access to hemato-oncology healthcare services in Almaty, Kazakhstan. Methods We retrospectively analyzed patient data from two tertiary centers, City Clinical Hospital 7 (H7) and Kazakh Institute of Oncology and Radiology (KazIOR), from March 1, 2019, to February 28, 2022. Variables included age, gender, residence, hospitalization rate, treatment outcomes (discharged/deceased/transferred), diagnoses (acute leukemia, lymphoproliferative diseases, myeloproliferative diseases), and referral sources. The Statistical Yearbook of Kazakhstan provided comparative data. Results From 2019-2022, 6,763 hemato-oncology hospitalizations were registered: 3,583 in H7 and 3,180 in KazIOR. The mean age was 55.04 (SD = 16.07) for females and 51.2 (SD = 16.7) for males. Urban and rural patient proportions were 6,191 (92%) and 571 (8.4%), respectively (Chi-square 13.8, P = 0.001). Fewer patients were discharged in 2020-2021 (n = 2,047) compared to 2019-2020 (n = 2,387) and 2021-2022 (n = 2,081) (Chi-square 20.09, P = 0.003). The death rate was higher in 2020-2021 (3.5%) than in 2019-2020 (3.2%) and 2021-2022 (2.6%) (Chi-square 20.09, P = 0.003). Emergency admissions were 403 (19%) in 2020-2021, 368 (14.8%) in 2019-2020, and 394 (18.3%) in 2021-2022 (Chi-square 2,231, P < 0.001). Transfers from other hospitals increased by 12.4% in 2020-2021. Conclusions The COVID-19 pandemic negatively impacted access to hemato-oncology services, increasing mortality. Further studies are needed to understand the factors affecting hospitalization and mortality trends during healthcare crises. Funding: Grant No. AP09260497.
