本研究利用個案醫院之病人安全中心放射科 HRR 門診病患通報資訊資料庫，統計某一時期之門診病患通報數量，以及常發生在門診之警示值檢查項目、種類，常發生警示值之臨床科別進行分析，並輔以 QUIS Model 人機介面使用滿意度之問卷來評量各臨床科醫師對使用HRR 系統的滿意度。
研究結果顯示，放射科 HRR 資料庫共 489 筆，問卷回收總數 103 份，有效回收問卷為 94 份，個案醫院放射科高風險警示系統的使用滿意度頗受臨床醫師肯定，平均滿意度為 3.91。門診病患 HRR 通報多集中於：胸腔內科、神經內外科以及一般外科，醫師透過 HRR 系統協助，可清楚瞭解病人狀況及臨床處置的優先順序；門診病患超出臨床醫師預判的潛在危急疾病，藉由放射科 HRR 通報，病患在檢查後3日內回診佔總資料人數近6成。受訪之臨床科醫師在接受通報方式以「手機簡訊」得到較高的使用滿意度；年齡層 41-50歲及51歲以上的主治醫師，對於警示訊息的及處理病患安全的經驗較其他年齡層顯著；職務別結果呈現與年齡層相似，收到 HRR 通報之主治醫師，對 HRR 的感受性較不常收到及從沒收到訊息的醫師來的顯著。不同服務科別的臨床醫師皆會檢視來自放射科通報之警示訊息，且多數醫師能在30分鐘以內聯絡危急病人回診做進一步處理。
根據本研究的結果，我們可瞭解個案醫院 HRR 系統使用狀況，及提供未來改善方向，期許藉由利用資訊科技來提升病人安全。

This research is based on the Patient Safety Center HRR database of outpatient of Radiology in single-cased hospitals. It estimates the number of the announcedoutpatients during a period and frequently happen reminding Exam item and Exam type. It also analyzes clinical department with a user satisfied questionnaire of QUISModel to evaluate physicians using HRR system。
The research shows that 489 are distributed from the Radiology of HRR database. The sample of 120 physicians, total responses of satisfaction questionnairesare 103, and 94 (78.33%) are deemed effective. Most physicians at Radiologyapprove the use of HRR system with a satisfactory rate of 3.91. Most outpatient HRRannouncements are in Chest Medical Department, Neurology Medicine, and GeneralSurgery. With the aid of HRR system, physicians can clearly understand the priorityof patient situation and clinical take care. By Radiology HRR announced, when theoutpatient goes beyond the physician’s expecting potentially hazard disease, nearly60% of the patients will return within 3 days.
By mobile news-letter, we get more satisfaction among interviewed physicians. In addition, the physicians that are between 41 to 50 age as well as above 51 age have more experience of remind message and deal with patient safety than other ages. Similar to the above comparison, the sensitivity of the physicians that have everreceived HRR announcements is more remarkable than those who have never or seldom received HRR announcements. All physicians survey the warning information from Radiology HRR, and most of them will contact exigent patients to come back tothe hospital within 30 minutes to do further treatment.
According to the result of this research, we can learn how hospitals use HRR system and provide future improvements. We hope to promote the patient safety byinformation technology.
