Practical introduction of telenursing for chronic respiratory failure patients for preventing hospital readmission of which increasing rapidly into Japan.

为维持和维持慢性呼吸衰竭家庭氧疗（HOT）患者的日常生活，采用自我监测的方法，利用触摸屏PC终端，研制了HOT患者远程监护系统。远程护理的效果通过随机对照试验进行了检查，29名HOT患者同意参加研究，并随机分配到干预组（n=16）或对照组（n=13）。干预组每天使用HOT远程护理系统，连续3个月，并对两组进行成本-效果分析。因此，在三个月的调查期间，两组的呼吸加重症状发生率和再入院率没有显著差异。但干预组的成本-效果比（CER）和由干预期间的医疗费用和非急性发作比率计算的增量成本-效果比（ICER）均高于对照组。提示该远程护理系统对降低HOT患者的医疗费用是有效的。

To maintain and keep continuous daily life for the chronic respiratory failure patients with Home Oxygen Therapy(HOT), we developed Telenursing system for HOT patients by self- monitoring methods and using touch panel PC terminal. The effect of the telenursing was examined by the randomized-controlled trial and twenty -nine HOT patients consented to participate in the study and were randomly assignment to the intervention (n=16) or control group (n=13). Intervention group was used HOT telenursing system every day for three months and cost-effectiveness was examined between both groups. As a result, a significant difference was not found in the occurrence of the respiratory exacerbation symptoms and readmission ratio for both groups for three month investigation periods. However, the cost-effectiveness ratio (CER) and the incremental cost effectiveness ratio (ICER) which calculated from the medical fee and non-exacerbation ratio of the intervention period were both higher in the intervention group. It was suggested that this telenursing system might be effective for the decrease of the medical cost for HOT patients.
