This study examines nurse-related clinical nonlicensed personnel (CNLP) in U.S. hospitals between 2010 and 2014, including job categories, trends in staffing levels, and the possible relationship of substitution between this group of workers and registered nurses (RNs) and/or licensed practical nurses (LPNs).
We used 5 years of data (2010-2014) from an operational database maintained by Premier, Inc. that tracks labor hours, hospital units, and facility characteristics.
We assessed changes over time in the average number of total hours worked by RNs, LPNs, and CNLP, adjusted by total patient days. We then conducted linear regressions to estimate the relationships between nurse and CNLP staffing, controlling for patient acuity, volume, and hospital fixed effects.
The overall use of CNLP and LPN hours per patient day declined from 2010 to 2014, while RN hours per patient day remained stable. We found no evidence of substitution between CNLP and nurses during the study period: Nurse-related CNLP hours were positively associated with RN hours and not significantly related to LPN hours, holding other factors constant.
Findings point to the importance of examining where and why CNLP hours per patient day have declined and to understanding of the effects of these changes on outcomes.
本研究调查了2010年至2014年美国医院中与护士相关的临床非持证人员(CNLP),包括工作类别、人员配备水平趋势,以及这群工作人员与注册护士(RN)和/或执业护士(LPN)之间可能的替代关系。
我们使用了Premier公司维护的运营数据库中5年的数据(2010 - 2014年),该数据库跟踪工时、医院科室和机构特征。
我们评估了按总住院日调整后的RN、LPN和CNLP总工作小时数随时间的变化。然后我们进行线性回归,以估计护士和CNLP人员配备之间的关系,并控制患者病情严重程度、工作量和医院固定效应。
2010年至2014年,每位患者每天CNLP和LPN的总体使用时间下降,而每位患者每天RN的工作时间保持稳定。在研究期间,我们没有发现CNLP和护士之间存在替代关系的证据:在其他因素不变的情况下,与护士相关的CNLP工作时间与RN工作时间呈正相关,与LPN工作时间无显著关系。
研究结果表明,研究每位患者每天CNLP工作时间下降的地点和原因以及理解这些变化对结果的影响具有重要意义。
