This study addresses the effect of the installation and use of a telecardiology system on the intensive care length of stay of very low birthweight (VLBW) newborn infants.
A retrospective comparison of 314 VLBW infants admitted to one of two neonatal intensive care units for a three year period from calendar years 1994 through 1996. A regression model was constructed to predict the intensive care length of stay while controlling for known risk factors.
Telemedicine's effect is to reduce the intensive care length of stay and it both statistically significant (p < 0.05) and practically significant, reducing the intensive care length of stay by over 17%. The reduction in length of stay is greater at lower birthweights.
Under the circumstances present in this study, telemedicine has been an effective intervention to reduce the intensive care length of stay.
本研究探讨远程心脏病学系统的安装和使用对极低出生体重（VLBW）新生儿重症监护住院时长的影响。
对1994年至1996年这三年间入住两个新生儿重症监护病房之一的314名VLBW婴儿进行回顾性比较。构建回归模型以预测重症监护住院时长，同时控制已知风险因素。
远程医疗的作用是缩短重症监护住院时长，这在统计学上具有显著意义（p < 0.05）且在实际应用中也具有显著意义，使重症监护住院时长减少了17%以上。出生体重越低，住院时长的减少幅度越大。
在本研究的条件下，远程医疗是缩短重症监护住院时长的有效干预措施。
