Objective: To determine the impact of transferring a pediatric population to mechanical ventilator dependency units (MVDUs) or to home mechanical ventilation (HMV) on bed availability in the pediatric intensive care unit (ICU).Methods: This is a longitudinal, retrospective study of hospitalized children who required prolonged mechanical ventilation at the MVDU located at the Hospital Auxiliar de Suzano, a secondary public hospital in São Paulo, Brazil. We calculated the number of days patients spent at MVDU and on HMV, and analyzed their survival rates with KaplanMeier estimator.Results: Forty-one patients were admitted to the MVDU in 7.3 years. Median length of stay in this unit was 239 days (interquartile range = 102-479). Of these patients, 22 came from the ICU, where their transfer made available 8,643 bed-days (a mean of 14 new patients per month). HMV of eight patients made 4,022 bed-days available in the hospital in 4 years (a mean of 12 new patients per month in the ICU). Survival rates of patients at home were not significantly different from those observed in hospitalized patients. Conclusion:A hospital unit for mechanical ventilator-dependent patients and HMV can improve bed availability in ICUs. Survival rates of patients who receive HMV are not significantly different from those of patients who remain hospitalized. J Pediatr (Rio J) IntroduçãoAs crianças dependentes de ventilação mecânica são um grupo de pacientes pediátricos com necessidades complexas de tratamento, devido ao uso contínuo de aparelhos para fornecer ventilação mecânica e às hospitalizações prolongadas. Essa população vem crescendo nos últimos anos 1 , como resultado dos avanços tecnológicos no tratamento de pacientes crônicos graves, e também do aumento do acesso público aos recursos médicos.Mesmo quando os pacientes estão clinicamente estáveis, muitos permanecem hospitalizados em unidades de terapia
