The 2009-2010 norovirus season was reported anecdotally by infection prevention and control teams (IPCTs) to be one of the worst seasons in Scotland. At its peak, Health Protection Scotland's (HPS) weekly point prevalence identified that 53 wards were closed.
To develop an annual cycle of learning lessons and improving systems to reduce the impact and incidence of norovirus outbreaks in Scotland.
An analysis of two end-of-year norovirus season evaluations (2009-2010 and 2010-2011) by IPCTs in Scotland using a national Plan, Do, Study, Act (PDSA) model.
The first evaluation (2009-2010) identified that IPCTs responded well when outbreaks were reported, but were not optimally prepared for the season. In addition, IPCTs had little data to describe their particular problems in detail. HPS planned for the 2010-2011 season with tools to optimize preparedness and norovirus management. The second evaluation (2010-2011) identified much more proactive responses to both preparedness and norovirus management.
This national PDSA cycle has led to system improvements designed to reduce the incidence and impact of norovirus in NHS Scotland. The incidence of norovirus was reduced in the 2011-2012 season; however, confounding from the variation in circulating viruses makes it difficult to measure any effect of the system improvements. As noroviruses challenge the health service every year, mainly in winter months, the end-of-season evaluations can be used to improve planning for subsequent seasons to share and demonstrate good practice. As more years of data become available for analysis, the impact of system improvements will become measurable.
感染预防和控制团队（IPC 团队）口头报告称，2009-2010 年诺如病毒季节是苏格兰遭遇的最严重季节之一。在高峰期，苏格兰公共卫生局（HPS）的每周时点患病率表明有 53 个病房关闭。
制定年度学习经验和改进系统的周期，以减少诺如病毒在苏格兰爆发的影响和发病率。
苏格兰 IPC 团队使用国家计划、执行、研究、行动（PDSA）模型对两个年终诺如病毒季节评估（2009-2010 年和 2010-2011 年）进行分析。
第一次评估（2009-2010 年）表明，当爆发报告时，IPC 团队反应良好，但对该季节的准备工作并非最佳。此外，IPC 团队几乎没有数据详细描述其特定问题。HPS 为 2010-2011 赛季计划了工具，以优化准备工作和诺如病毒管理。第二次评估（2010-2011 年）发现，无论是在准备工作还是诺如病毒管理方面，反应都更加积极主动。
这种国家 PDSA 周期导致了旨在减少 NHS 苏格兰诺如病毒发病率和影响的系统改进。在 2011-2012 赛季，诺如病毒的发病率有所下降；然而，由于循环病毒的变化，难以衡量系统改进的任何效果。由于诺如病毒每年都对医疗服务构成挑战，主要在冬季月份，因此可以利用年终评估来改进后续季节的计划，以分享和展示良好做法。随着更多年份的数据可供分析，系统改进的影响将变得可衡量。
