BACKGROUND: In Asian countries, nationwide data on patients undergoing home mechanical ventilation are limited. METHODS: This study investigated the prevalence and primary indications for home mechanical ventilation use in South Korea by using nationwide registry data from the National Health Insurance Service. RESULTS: The study period included a total of 4,785 subjects on home mechanical ventilation (mean ± SD age, 56.0 ± 23.9 y; females, 40.1%). The estimated overall prevalence of home mechanical ventilation use in South Korea was 9.3 per 100,000, with a prevalence of 6.3 per 100,000 among children (ages < 15 y). The most common primary diagnoses were neuromuscular diseases (42.0%) and lung and/or airway diseases (27.7%). The prevalence of lung and/or airway and cerebrovascular diseases as the primary diagnosis increased with age (r = 0.310, P <.001; and r = 0.156, P <.001, respectively). Noninvasive ventilation was used by 37.2% of all the subjects, with the highest prevalence in those with neuromuscular diseases (54.4%) or chest wall diseases (53.4%). Noninvasive ventilation use was lowest among subjects with brain lesions. Home mechanical ventilation was most commonly prescribed by internists (41.3% of cases), followed by rehabilitation and neurology physicians. CONCLUSIONS: These data will aid in planning the optimal health-care system for users of home mechanical ventilation locally and will allow for comparison of home mechanical ventilation use rates among countries.
