品管圈活动在牙科手机管理中的应用效果

目的：探讨品管圈活动在牙科手机管理中的应用效果。方法将2011年下发的80把牙科手机作为对照组；2012年下发的72把牙科手机作为实验组。通过品管圈活动指导实验组手机的管理使用，对两组手机故障、零部件损坏率及管路堵塞率进行统计学分析。结果实验组手机通过品管圈活动手机故障率为6．9％，零部件损坏率为11．1％，管路堵塞率为6．9％，均低于对照组（23．8％，26．2％，28．8％），差异均有统计学意义（χ^2值分别为8．04，5．63，12．00；P＜0．01）。结论品管圈活动可有效查找牙科手机管理使用中的问题，针对问题提出切实可行的改进措施，进行监管实施后可明显控制手机的故障率，对科室来讲可起到减耗增效的积极作用。

Effect of quality control circle to manage dentistry handsets in stomatology department

Objective To explore the effects of quality control circle to cope with dentistry handsets on reducing expenditure and increasing benefits in stomatology department .Methods Eighty handsets （ distributed in 2011 ） were as control group compared with seventy two handsets （ distributed in 2012 ） as study group .By using the quality control circle management , the study analyzed and compared the malfunction rates including handsets malfunction , accessories malfunction and pipeline block .Results The rates of handsets malfunction , accessories malfunction and pipeline block in study group were 6.9%,11.1% and 6.9%, compared with 23.8%,26.2%, and 28.8%respectively in control group , the differences were statistically significant （χ^2 =8.04,5.63,12.00, respectively;P〈0.01）.Conclusions From the study, it could be seen that the quality control circle has high efficiency to find out and resolve handsets ’ malfunctions on time , and reduce controllable malfunctions resulting in low expenditure for handsets ’ malfunctions .
