Intensive care unit admission rates and factors associated following Autologous stem cell transplantation—real-world experience from a tertiary center in rural India

Purpose Infectious and other complications can necessitate admission to the intensive care unit (ICU) in autologous stem cell transplantation (ASCT). Data on need for ICU care, impact of various pre- and peri-transplant characteristics on requirement of ICU care and outcomes are scarce from the developing world. Methods A retrospective case record review of ASCT cases was conducted. Pre- and peri-transplant characteristics like infection within 4 weeks of transplant, mucositis, surveillance culture positivity, peri-transplant infections, comorbidity, and time to neutrophil and platelet engraftment were noted. Results A total of 109 patients underwent 109 ASCTs. Most common diagnosis was the plasma cell disorder in 75 (69%) patients. Forty-eight (45%) patients had peri-transplant infections. Fifteen (14%) patients had infections with multi-drug resistant (MDR) organisms. Fifteen (14%) patients required ICU care, the most common reason being hypotension in nine patients (8.3%). Four patients (3.7%) required non-invasive ventilation, and one (0.9%) required invasive ventilation. Mortality rate was 1.8% (two patients). Factors associated with the need for ICU care were time to platelet engraftment (median 15 days among those required ICU care versus 13 days who did not, p = 0.04) and presence of peri-transplant infection showed a trend toward ICU care need (19% among those required ICU care versus 7% in those who did not, p = 0.05). Conclusion Delayed platelet engraftment was associated with the need for ICU care and peri-transplant infections were associated with a trend toward need for ICU care.
