To examine the effect of nursing practice environments on outcomes of hospitalized cancer patients undergoing surgery.
Secondary analysis of cancer registry, inpatient claims, administrative and nurse survey data collected in Pennsylvania for 1998-1999.
Nurse staffing (patient to nurse ratio), educational preparation (proportion of nurses holding at least a bachelor's degree), and the practice environment (Practice Environment Scale of the Nursing Work Index) were calculated from a survey of nurses and aggregated to the hospital level. Logistic regression models predicted the odds of 30-day mortality, complications, and failure to rescue (death following a complication).
Unadjusted death, complication, and failure to rescue rates were 3.4, 35.7, and 9.3 percent, respectively. Nurse staffing and educational preparation of registered nurses were significantly associated with patient outcomes. After adjusting for patient and hospital characteristics, patients in hospitals with poor nurse practice environments had significantly increased odds of death (odds ratio, 1.37; 95 percent confidence interval, 1.07-1.76) and of failure to rescue (odds ratio, 1.48; 95 percent confidence interval, 1.07-2.03). Receipt of care in National Cancer Institute-designated cancer centers significantly decreased the odds of death, which can be explained partly by better nurse practice environments.
This study is one of the first to examine the predictive validity of the National Quality Forum's endorsed measure of the nurse practice environment. Improvements in the quality of nurse practice environments could reduce adverse outcomes for hospitalized surgical oncology patients.
探讨护理实践环境对接受手术的住院癌症患者预后的影响。
对1998 - 1999年宾夕法尼亚州收集的癌症登记、住院患者索赔、行政和护士调查数据进行二次分析。
护士人员配备(患者与护士比例)、教育程度(至少拥有学士学位的护士比例)以及实践环境(护理工作指数实践环境量表)通过对护士的调查计算得出,并汇总到医院层面。逻辑回归模型预测了30天死亡率、并发症发生率和抢救失败率(并发症后死亡)。
未经调整的死亡率、并发症发生率和抢救失败率分别为3.4%、35.7%和9.3%。护士人员配备和注册护士的教育程度与患者预后显著相关。在调整患者和医院特征后,护士实践环境较差的医院中的患者死亡几率(优势比,1.37;95%置信区间,1.07 - 1.76)和抢救失败几率(优势比,1.48;95%置信区间,1.07 - 2.03)显著增加。在国立癌症研究所指定的癌症中心接受治疗显著降低了死亡几率,这部分可以通过更好的护士实践环境来解释。
本研究是最早检验国家质量论坛认可的护士实践环境测量方法预测效度的研究之一。改善护士实践环境质量可降低住院外科肿瘤患者的不良预后。
