某教學醫院兒科病房噪音程度改善方案

Noise Level Improvement Plan for the Pediatric Ward in a Teaching Hospital

本專案為降低某教學醫院兒科病房噪音改善方案。經由滿意度調查發現，「保持病房安寧」的滿意度僅達79.3％，故於2004年5月13日成立病房噪音改善小組，藉由調查及測量，確立病房中發生最多前五項噪音源為拉放床欄聲、工作車推動聲、小孩哭鬧聲、電話鈴聲及工作人員喧嘩聲，此五項噪音之平均分貝數為73.6分貝，高於環保署所設定的標準。於是在實施教育宣導、調整儀器音量、定時進行修繕等改善措施兩個月後，此五項噪音源之分貝數及頻率，分別可降低10分貝及20%以上。由此得知，本噪音改善方案可有效的提升病房安寧程度，期望未來能將此方案推展至其他單位，以全面提升醫院之安寧程度。

This study aimed to improve the noise level of the pediatric ward in a medical center in metropolitanTaipei, Taiwan. Because the satisfaction survey showed that the satisfaction level of theitem 'maintaining quietness in the ward' was only 79.3%, the ward noise level improvement teamwas established on May 13, 2004. Based on the questionnaire survey and actual measurement, thefive most frequently occurring noise sources in the ward included the sounds of pulling and releasingthe bed handrails, sounds of pushing work carts, crying and nagging sounds of children, phonesringing, and noises made by staff. The average decibel of those five noises was 73.6, which washigher than the hospital noises threshold specified by the Environmental ProtectionAdministration.After implementing the improvement plan for two months, the measured noise level decreased by10 decibels, and the frequency of occurrence was reduced by over 20%. Thus, a noise improvementplan can effectively improve the quietness in the ward. Hopefully this plan can be promoted toother wards to lift the overall calmness of the medical environment.Key words:
