To quantify the prevalence and nature of adverse events in acute Irish hospitals in 2015 and to assess the impact of the National Clinical Programmes and the National Clinical Guidelines on the prevalence of adverse events by comparing these results with the previously published data from 2009.
A retrospective chart review of 1605 admissions to eight Irish hospitals in 2015, using identical methods to those used in 2009.
The percentage of admissions associated with one or more adverse events was unchanged (p=0.48) at 14% (95% CI=10.4% to 18.4%) in 2015 compared with 12.2% (95% CI=9.5% to 15.5%) in 2009. Similarly, the prevalence of preventable adverse events was unchanged (p=0.3) at 7.4% (95% CI=5.3% to 10.5%) in 2015 compared with 9.1% (95% CI=6.9% to 11.9%) in 2009. The incidence densities of preventable adverse events were 5.6 adverse events per 100 admissions (95% CI=3.4 to 8.0) in 2015 and 7.7 adverse events per 100 admissions (95% CI=5.8 to 9.6) in 2009 (p=0.23). However, the percentage of preventable adverse events due to hospital-associated infections decreased to 22.2% (95% CI=15.2% to 31.1%) in 2015 from 33.1% (95% CI=25.6% to 41.6%) in 2009 (p=0.01).
Adverse event rates remained stable between 2009 and 2015. The percentage of preventable adverse events related to hospital-associated infection decreased, which may represent a positive impact of the related national programmes and guidelines.
量化 2015 年爱尔兰急性医院不良事件的发生率和性质，并通过将这些结果与之前 2009 年发表的数据进行比较，评估国家临床方案和国家临床指南对不良事件发生率的影响。
对 2015 年 8 家爱尔兰医院 1605 例住院患者进行回顾性病历审查，采用与 2009 年相同的方法。
2015 年，与不良事件相关的住院人数百分比（p=0.48）保持不变，为 14%（95%CI=10.4%至 18.4%），而 2009 年为 12.2%（95%CI=9.5%至 15.5%）。同样，2015 年可预防不良事件的发生率（p=0.3）保持不变，为 7.4%（95%CI=5.3%至 10.5%），而 2009 年为 9.1%（95%CI=6.9%至 11.9%）。2015 年可预防不良事件的发生率密度为每 100 例住院患者发生 5.6 例不良事件（95%CI=3.4 至 8.0），而 2009 年为每 100 例住院患者发生 7.7 例不良事件（95%CI=5.8 至 9.6）（p=0.23）。然而，由于医院相关感染导致的可预防不良事件百分比从 2009 年的 33.1%（95%CI=25.6%至 41.6%）降至 2015 年的 22.2%（95%CI=15.2%至 31.1%）（p=0.01）。
2009 年至 2015 年期间，不良事件发生率保持稳定。与医院相关感染相关的可预防不良事件百分比下降，这可能表明相关国家方案和指南产生了积极影响。
