This exploratory study used archived hospital data to determine whether the call light use rate and the average call light response time contribute to the fall and the injurious fall rates in acute care settings.
Inpatients often use call lights to seek nurses' attention and assistance. Although implied in patient safety, no studies have examined data related to the call light use or the response time to call lights collected via existing tracking mechanisms to monitor nursing practice.
The study was conducted in a Michigan community hospital and used archived hospital data for analyses for the period from February 2007-June 2008. The unit of analysis was unit-week.
The call light use rate per patient-day was calculated based on information retrieved from the call light tracking system. The average response time in seconds was used as generated from the tracking system. The fall and injurious fall rates per 1000 patient-days were calculated based on the fall incident reports. SPSS was used for data analyses. One-way ANOVA and correlation analyses were conducted.
More calls for assistance related to less fall-related patient harm. Surprisingly, longer response time to call lights also related to fewer total falls and less fall-related patient harm. Generally speaking, more call light use related to longer response times.
This study's findings challenged the appropriateness of targeting the goals of reducing the frequency of call light use and the fall rates as two outcome indicators of conducting hourly patient rounds.
Encouraging call light use is a key to reducing injurious fall rates. Unit managers should routinely monitor the trend of the call light use rate and ensure that the call light use rate is maintained at least above the mean rate.
本探索性研究使用存档的医院数据来确定呼叫灯使用率和平均呼叫灯响应时间是否会导致急性护理环境中的跌倒和伤害性跌倒率。
住院患者经常使用呼叫灯来寻求护士的注意和帮助。尽管这与患者安全有关，但尚无研究检查过通过现有跟踪机制收集的与呼叫灯使用或呼叫灯响应时间相关的数据，以监测护理实践。
该研究在密歇根州的一家社区医院进行，使用存档的医院数据进行了 2007 年 2 月至 2008 年 6 月期间的分析。分析单位为单位周。
根据从呼叫灯跟踪系统中检索到的信息，计算每位患者每天的呼叫灯使用率。平均响应时间以跟踪系统生成的秒数为单位。根据跌倒事故报告计算每千名患者日的跌倒和伤害性跌倒率。使用 SPSS 进行数据分析。进行了单因素方差分析和相关分析。
更多的求助呼叫与较少与跌倒相关的患者伤害有关。令人惊讶的是，呼叫灯的响应时间延长也与总跌倒次数减少和与跌倒相关的患者伤害减少有关。一般来说，呼叫灯使用越多，响应时间就越长。
本研究的结果挑战了将减少呼叫灯使用频率和跌倒率作为进行每小时患者巡视的两个结果指标的目标的适当性。
鼓励使用呼叫灯是降低伤害性跌倒率的关键。病房管理人员应定期监测呼叫灯使用率的趋势，并确保呼叫灯使用率至少保持在平均水平以上。
