目的：醫療過程經常需要接觸病人的身體與私密的資訊，就醫隱私的議題更加需要重視。本研究嘗試探討門診病人對各隱私議題的重視度與達成度間之落差。方法：本研究採取橫斷式研究，以中部某區域教學醫院病人為研究對象。問卷內隱私議題分為生理、心理、社會與資訊等四個構面，分別詢問病人對各隱私議題之重視度與達成度，並據以計算其缺口，測量尺度為李克特5點尺度。回收資料以描述性統計、t檢定、單因子變異數分析、重複量數變異數分析以及多元複迴歸分析。本研究有效回收問卷為289份，有效回收率96.33%。結果：根據結果顯示，資訊隱私是受訪者最重視，但也是缺口最大的構面，在各問項中，重視度較高者多為資訊隱私與生理隱私構面，達成度較高的多為社會隱私與生理隱私構面，缺口較大的多為資訊隱私構面。病人個人特性的差異並不明顯，僅女性在各個隱私構面的重視度顯著高於男性，年齡愈輕的病人對生理與資訊的隱私愈重視，達到程度與缺口大多無顯著差異。結論：根據研究結果可以發現，病人對各項隱私議題均相當重視，而對醫院提供之隱私保護的滿意程度也高，但對資訊隱私感受的落差較大。因此，醫院應不斷強化醫護人員隱私議題的警覺，避免在不經意中洩漏病人的隱私。

Objectives: The medical process often requires contact with the patient's body and private information, and the issue of medical privacy needs more attention. This study attempts to explore the gap between the expectation and perception of privacy issues among outpatients. Method: This study was a cross-sectional study of patients from a regional teaching hospital in central Taiwan. The privacy issues in the questionnaire were divided into four dimensions: physical, psychological, social, and informational. Patients are asked about the expectation and perception of each privacy issue based on the Likert 5-point scale, and the gap was calculated as perception minus expectation. This study used descriptive statistics, t-test, one-way ANOVA, repeated measured ANOVA, and multiple regression analysis. A total of 289 valid questionnaires were collected, and the effective response rate was 96.33%. Results: Informational privacy was the highest dimension of expectation, but it is also the one with the largest gap. Among the various items, those with the highest degree of expectation were mostly the aspects of informational privacy and physical privacy, and those with the highest degree of perception were mostly social and physical privacy , most of which were gaps in informational privacy. Conclusion: Patients attached great expectation to various privacy issues, and had a high degree of perception with the privacy protection provided by the hospital, but the gap in informational privacy perceptions was larger. Therefore, hospitals should continue to educate healthcare staff on their privacy awareness and avoid inadvertent disclosure of patient privacy.
