卫生保健提供者在大规模卫生应急规划、检测、响应、恢复和与公众沟通方面发挥着重要作用。卫生保健提供者在应急准备和响应角色中的有效性部分取决于公共卫生机构以最大限度地提高信息传递、接收、认为可信并在适当时采取行动的可能性的方式传达信息。然而，在紧急情况下，卫生保健提供者可能会被众多国家、州、本地和专业的沟通渠道。我们进行了一项警觉疲劳研究，作为一项大型随机对照试验的子研究，旨在确定公共卫生机构和提供者之间沟通公共卫生信息的最有效方法。我们报告了一项分析，分析了公共卫生信息量/频率对召回特定信息内容的影响，以及信息通信速率对医疗保健提供者警报疲劳的影响。参加大型研究的卫生保健提供者（n=528）被随机分配通过电子邮件，传真，短信服务（SMS或手机短信）接收公共卫生信息，或不接收信息的对照组。在12个月内，每季度发送一次基于具有公共卫生意义的真实的事件的研究消息，并在消息发送日期后5-10天进行关于消息接收和主题回忆的随访电话访谈。在大流行期间，当发送大量消息时，由于大量消息产生的“噪音”，警报疲劳可能会影响回忆是否收到特定消息的能力。为了确定发送研究信息时“噪音”的影响，我们将医疗保健提供者对研究信息主题的回忆与发送给医疗保健提供者的当地公共卫生信息的数量进行了比较。我们计算了在每个研究消息周围的时间段内，每个提供者从当地公共卫生部门收到的消息的平均数量，以及提供者对研究消息内容的回忆。我们发现，回忆率与每周收到的平均信息数量成反比：每周每增加一条当地公共卫生信息，回忆研究信息内容的几率就会减少41.2%（p < 0.01），95% CI [0.39，.87]。据我们所知，这是第一个记录警觉疲劳对医疗保健提供者回忆信息的影响的研究。我们的研究结果表明，通过众多的沟通渠道提供的信息过于频繁和/或重复可能会对医疗保健提供者有效地回忆紧急信息的能力产生负面影响。在紧急情况下，让卫生保健提供者和其他一线响应者了解情况至关重要。传播警报、公告和其他信息的组织之间更好的协调可能会提高卫生保健提供者召回公共卫生紧急信息的能力，这可能会影响对公共卫生紧急信息的有效响应。
Health care providers play a significant role in large scale health emergency planning, detection, response, recovery and communication with the public. The effectiveness of health care providers in emergency preparedness and response roles depends, in part, on public health agencies communicating information in a way that maximizes the likelihood that the message is delivered, received, deemed credible and, when appropriate, acted on. However, during an emergency, health care providers can become inundated with alerts and advisories through numerous national, state, local and professional communication channels. We conducted an alert fatigue study as a sub-study of a larger randomized controlled trial which aimed to identify the most effective methods of communicating public health messages between public health agencies and providers. We report an analysis of the effects of public health message volume/frequency on recall of specific message content and effect of rate of message communications on health care provider alert fatigue. Health care providers enrolled in the larger study (n=528) were randomized to receive public health messages via email, fax, short message service (SMS or cell phone text messaging) or to a control group that did not receive messages. For 12 months, study messages based on real events of public health significance were sent quarterly with follow-up telephone interviews regarding message receipt and topic recall conducted 5–10 days after the message delivery date. During a pandemic when numerous messages are sent, alert fatigue may impact ability to recall whether a specific message has been received due to the “noise” created by the higher number of messages. To determine the impact of “noise” when study messages were sent, we compared health care provider recall of the study message topic to the number of local public health messages sent to health care providers. We calculated the mean number of messages that each provider received from local public health during the time period around each study message and provider recall of study message content. We found that recall rates were inversely proportional to the mean number of messages received per week: Every increase of one local public health message per week resulted in a statistically significant 41.2% decrease (p < 0.01), 95% CI [0.39, .87] in the odds of recalling the content of the study message. To our knowledge, this is the first study to document the effects of alert fatigue on health care providers’ recall of information. Our results suggest that information delivered too frequently and/or repetitively through numerous communication channels may have a negative effect on the ability of health care providers to effectively recall emergency information. Keeping health care providers and other first-line responders informed during an emergency is critical. Better coordination between organizations disseminating alerts, advisories and other messages may improve the ability of health care providers to recall public health emergency messages, potentially impacting effective response to public health emergency messages.
