Science and Technology,W uhan 430030,China) Abstract:0bjective To increase the rate of effective taking of se1f-presc ribed medications among hospitalized patients through quali— ty control circle(QCC).Methods A QCC was set up,and the topic of how to help hospitalized patients to effectively take self—pre— scribed m edications was selected.The causes w hy hospitalized patients failed to effectively take self—prescribed m edications w ere analyzed, then im provem ent schem es and plans w ere form ulated,and im plem ented,and the effect was evaluated.Results After the implementation of the QCC activities, the rate of arbitrary taking of self—prescribed medications among hospitalized patients dropped significantly,with the rate of taking medications with irregularly spaced intervals dropping to 6.0 ,the rate of taking wrong doses to 4.0 ,both achieving preset goals.However,the rate of missing a dose(2.3 )was slightly above the preset goal of 2.0 .The rates of quality parameters,except taking expired medications,had significant differences before and after the imple— mentation of the QCC activities (P< 0.01 for al1).Conclusion M any factors conspired to cause inappropriate taking of self—pre— scribed m edications among hospitalized patients.Qcc activities help to systematically analyze the leading causes and establish im— provement schemes.W ith this method,the rate of effective taking of self_prescribed medications among hospitalized patients has been enhanced, which also boosts their recovery.
