目的 了解国内医院品质管理圈（品管圈）活动的发展现况，为品管圈活动的进一步推广和研究提供依据。 方法 2012年2月－6月采用文献研究法，检索公开发表于国内学术期刊的有关品管圈活动的所有文献，并阅读分析全文。 结果 共收集符合要求的文献125篇，文献主要来源于我国东部地区、类型以回顾性分析为主，主题内容侧重护理质量与药事服务管理。 结论 我国医院品管圈活动发展迅速，涉及面广，但研究方法、研究内容如社区发展等方面仍亟待进一步加强。
Objective To explore the effect of sequential nutritional intervention mode on improving early postoperative nutritional status in patients with gastric cancer. Methods A total of 30 patients who underwent radical gastrectomy for gastric cancer in the Department of Gastrointestinal Surgery, Ningbo No.2 Hospital between June and August 2022 were selected as the tiral group by convenience sampling, and another 30 patients who underwent radical gastrectomy for gastric cancer between September 2021 and January 2022 were retrospectively selected as the control group. The trial group received the sequential nutritional intervention model constructed by quality control circle activities in the Department of Gastrointestinal Surgery, and the control group received routine nutritional support. The nutritional status and quality of life of the two groups were evaluated one month after discharge. Results Before intervention, there was no statistically significant difference in the Patient-Generated Subjective Global Assessment (PG-SGA) score, serum albumin, serum prealbumin, body weight, or Quality of Life Questionnaire Core 30 (QLQ C30) score between the two groups (P>0.05). After intervention, both groups showed improvements in PG-SGA score, serum albumin, and serum prealbumin compared to before intervention (P<0.05); there was no significant change in body weight in the trial group (P>0.05), while the control group experienced a decrease in body weight (P<0.05); the trial group showed an improvement in QLQ C30 score (P<0.05), whereas the control group did not show significant change in QLQ C30 score (P>0.05). Compared to the control group after intervention, the trial group showed better PG-SGA score (7.97±1.65 vs. 8.83±1.26), serum albumin level [(40.61±1.30) vs. (39.93±0.78) g/L], serum prealbumin level [(0.266±0.030) vs. (0.229±0.051) g/L], body weight [(63.12±7.39) vs. (58.17±9.18) kg], and QLQ C30 score (62.63±9.01 vs. 57.23±7.13), with all differences being statistically significant (P<0.05). Conclusion Sequential nutritional intervention model is helpful to improve the early nutritional status and quality of life of patients after radical gastrectomy, and has clinical promotion value.
