We aimed to clarify the etiology, incidence, prevalence and effect of HIMV on survival in the Finnish population.Methods: We studied the use of HIMV from the Finnish HIMV-patients{\textquoteright} (age over 16 years) medical files from 1.1.2015 to 1.1.2019. Information was collected of e.g. diagnosis leading to HIMV, time from diagnosis to HIMV initiation, the length of HIMV, mortality and basic sociodemographic data.Results: In January 2015 we had 107 HIMV patients. During the follow up period we got 31 (22.5\%) new patients and 43 (31.2\%) died resulting in a total of 138 patients. On 1.1.2019 we had 95 HIMV-patients and the prevalence in Finland was 2.1/100 000. The most common diagnosis were motor neurone disease (N=37, 26.8\%), spinal cord injuries and diseases (N=27, 19.6\%), and muscle dystrophies (N=24, 17.4\%). The mean age of the patients was 55 years (SD{\textpm} 17.8), the mean time from diagnosis to HIMV initiation was 7.6 years (SD{\textpm} 12.2), and the mean length of HIMV on 1.1.2019 was 12.6 years (SD{\textpm} 11.4). 113 patients (81.9\%) used HIMV 24 h/day. Among all the deceased patients the mean time in HIMV was 11.6 (SD{\textpm} 12.4) with a lifetime of 63.2 years (SD{\textpm} 14.2).Conclusions: HIMV is a rare treatment. Today, the use of non-invasive ventilation (NIV) in chronic hypoventilation has mostly replaced the use of HIMV. The long-term nature of HIMV and the need for 24h care-giving is recommendable to notice before HIMV initiation. It is also noticeable, that the time from diagnosis to HIMV initiation, treatment length~and survival varied greatly depending~on the underlying diagnosis.FootnotesCite this article as: ERJ Open Research 2020; 6: Suppl. 4, 02.This is an ERS Respiratory Failure and Mechanical Ventilation Conference abstract.
