Objective To summarize the characteristics of medical service patterns at Grenada station of Mission Harmony-2015 so as to provide reference for future overseas services in similar island countries .Methods After detailed analysis of actual conditions of the countries visited and efficient communication with host country health organizations , we made an appropriate adjustment of the medical service pattern , which involved multi-site screening of general patients , followed by intensive checkups and treatment aboard the hospital ship .Results The procedure of diagnosis and treatment was streamlined and the efficacy of medical services was significantly enhanced to meet the maximum medical demand of local residents.Grenada became a station with the largest number of patients who received top-quality fee-free healthcare during Mission Harmony-2015 .Conclusion Adjustment of medical service patterns according to the actual conditions could deliver a desired effect during overseas missions .

Objective? To explore the effects of Miller's pyramid principle on training for newly enrolled nurses in operation room. Methods? Totally 25 newly enrolled nurses in operation room who attended training for new nurses from July 2016 to June 2018 were included into the observation group. Miller's pyramid principle was incorporated into conventional training methods, and progressive and multilayer training was provided based on its theoretical framework. Another 22 newly enrolled nurses in operation room who attended training for new nurses from July 2014 to June 2016 were included into the control group who were trained using conventional methods. Theoretical performance, operation skill, case discussion, core competence self-evaluation and core competence evaluated by others were compared between the two groups. Results? The operation skill, case discussion, core competence self-evaluation and core competence evaluated by others of the observation group scored (88.72±3.10), (52.72±2.11), (144.44±23.87) and (133.44±18.32), respectively, higher than those of the control group, which were (85.27±3.95), (50.82±1.97), (122.64±22.61) and (115.68±14.01), respectively (t=-3.35, -3.18, -3.20, -3.69;P＜ 0.05). There was no statistically significant difference in theoretical performance score between the two groups (P＞0.05). Conclusions? The effects of Miller's pyramid principle were better than those of conventional methods, which can improve the overall quality and core competency of newly enrolled nurses in operation room.
