Clinical Communication Response Latency as an Operational Efficiency and Patient Safety Indicator in Acute Care Hospitals

Timely clinical communication is a core function of acute care, yet response latency remains poorly measured in most hospital environments. Peer-reviewed research published in the Journal of Patient Safety examines this gap, treating waiting time before response as a measurable, stratified patient safety indicator rather than a service metric.

The study was conceived and conducted independently by Ashish Singh, DBA, Rauland Regional Sales Director – International, Healthcare Technology, in his capacity as a doctoral researcher. Analyzing 16,000 nurse call events across three hospital environments, the research examines how communication infrastructure affects response time, escalation rates, and patient safety exposure.

Findings revealed stark differences across settings. In voice-enabled environments for example, median response time was 29 seconds with zero escalation events exceeding the 180-second safety threshold. In non-voice environments, median response times reached as high as 256 seconds, with ward-based night shift escalation rates climbing to 76%. For high-acuity patients, the gap was equally pronounced: 28 seconds in voice-enabled settings versus 80 to 88 seconds in non-voice environments.

The research introduces a dual-phase latency model that distinguishes verbal triage from physical intervention, identifying the interval during which a deteriorating patient may be calling without being heard as a central patient safety concern. It also applies Lean methodology to quantify the inefficient staff resource use nursing locomotion waste that results when they staff must physically enter a room to determine the nature of a call, offering a direct operational efficiency argument alongside the clinical safety findings.
