Why Every Second Matters in Hospital Emergency Code Activations

In cardiac arrest, stroke, trauma, and other emergency scenarios, every second directly affects survival. Yet most hospitals lose critical time to outdated, manual code activation workflows – and worse, don’t realize it.

Despite this, many hospitals continue to rely on fragmented communication systems that introduce hidden delays at every step of the emergency response chain.

This article explores why time-critical care demands clear processes, where hospitals commonly lose precious seconds, and how to eliminate these delays through better code activation workflows and technology.

Why Every Second Truly Matters in Emergency Care

The relationship between time to treatment and survival in many life threatening conditions has been extensively studied. Decades of research have established clear thresholds where hospital communication delays can lead to delays in care, which directly translate to worse outcomes. Below are a few examples.

‍

The Evidence Behind Time-Critical Care

Delays even of a few minutes materially reduce survival. For example, survival rates after VF cardiac arrest decrease approximately 7-10% with every minute that defibrillation is delayed. Research examining in-hospital cardiac arrests found that patients whose defibrillation was delayed had survival to discharge of 49% compared to 66% when defibrillation was rapid.

Communication delays can also lead to slower response times, creating delays in care. A large analysis of approximately 57,000 in-hospital cardiac arrests revealed that if CPR was delayed more than two minutes after arrest, survival dropped from 17.1% to 14.7%. Further, delays from CPR to defibrillation or epinephrine administration beyond two minutes were associated with progressively lower survival depending on the length of delay. Recent 2024 data reinforces this urgency: each minute delay to first defibrillation shock was associated with a 6% lower incidence of successful defibrillation.

In STEMI care, door-to-balloon time has become a universally recognized quality metric. Every 10 minutes of delay increases mortality. The window for intervention is narrow, and even small delays compound into meaningful harm. One study found that after implementing Code STEMI, the hospital experienced reduced door-to-balloon time, total cost, and length of stay of patients. Another hospital’s door-to-balloon time was significantly reduced by 130 minutes since the implementation of their Code STEMI activation workflow. 

The message is clear: faster activation leads to faster treatment, which leads to better survival.

Where Hospitals Commonly Lose Time

Emergency code activations involve multiple people, often across different departments and physical locations. Each handoff, each communication step, and each moment spent locating the right provider introduces potential delay.

Consider a typical hospital code STEMI activation scenario. A nurse on the floor recognizes signs of cardiac arrest and initiates the code. In many hospitals, this triggers a call to the switchboard. The operator must then locate the on-call cardiologist, page them, and potentially escalate to a backup provider. Meanwhile, the code team assembles, but without clarity on who’s responding or when they'll arrive.

This process introduces several common bottlenecks:

• Lack of acknowledgement: Traditional pagers don’t provide read receipts or acknowledgment, meaning clinicians have no way of knowing if the alert was received. This uncertainty creates hesitation and delays in escalation.
• Locating the right on-call provider: In organizations with complex on-call schedules, identifying the correct person to contact isn’t always straightforward. Switchboard operators may need to consult outdated schedules or make multiple calls, slowing down the response.
• Sequential call trees and switchboard bottlenecks: Manual, sequential alerting means that each provider is contacted one at a time. During high-volume periods, switchboard operators can face backlogs that further delay critical notifications and less urgent calls.
• Fragmented communication systems: When teams rely on a mix of pagers, phones, EHR alerts, and disparate messaging apps, important information gets lost in translation. Context is missing, escalation pathways are unclear, and there’s no unified source of truth.
• No real-time visibility into who is responding: Without confirmation mechanisms, teams operate in the dark. They don’t know if the cardiologist is two minutes away or still hasn’t seen the alert.
• Missing or slow escalation pathways: When primary responders don’t acknowledge an alert, escalation should be automatic and immediate. In many hospitals, however, escalation is manual, ad hoc, or nonexistent, leading to further delays as staff scramble to identify backup coverage.

Each of these delays may be small in isolation, but they accumulate and can make a real difference. A page that takes 90 seconds to be returned, a switchboard call that takes 30 seconds to connect, and a lack of automated escalation can easily add three to five minutes to activation time.

‍

The Metrics That Matter in Emergency Code Activations

Understanding where delays occur requires measuring the right things. Many hospitals track broad metrics like door-to-balloon time or overall code response times, but these aggregate measures can mask critical inefficiencies earlier in the activation chain.

To identify and eliminate delays, hospitals should track metrics across three categories: activation, clinical outcome, and device performance.

‍

Activation Metrics

• Recognition to code activation time: Measures the interval from when the emergency is first recognized to when the code is officially activated. Delays here often stem from hesitation, unclear protocols, or difficulty reaching the switchboard.
• Activation to acknowledgment time: Tracks how long it takes for the notified provider to confirm receipt of the alert. Long acknowledgment times suggest potential issues with pager reliability, alert fatigue, or providers missing notifications due to silent mode or do-not-disturb settings.
• Acknowledgement to arrival time: Captures how quickly the full code team assembles at the patient’s bedside. Even if the right providers are notified quickly, physical arrival can be delayed if team members are unclear on the location or if escalation protocols aren’t followed.

‍

Clinical Outcome Metrics

• Time to CPR and defibrillation: The standard measures for cardiac arrest response, these metrics directly correlate with survival and should be measured in seconds, not minutes. Time to defibrillation specifically highlights delays in equipment readiness and team coordination.
• Time to definitive management: Metrics that are specific to clinical scenarios, for example door-to-device or door-to-balloon time in STEMI, time to OR for trauma, and door-to-needle for stroke cases, where rapid intervention is critical to minimizing morbidity and mortality.

‍

Device Metrics

• Missed alerts: These occur when notifications fail to reach the intended recipient due to technical issues, silent mode, or provider unavailability. High rates of missed alerts may indicate systemic problems with communication infrastructure.
• Escalation failures: This happens when backup providers either not assigned or notified after the primary responder fails to acknowledge an alert. Tracking escalation failures exposes gaps in workflow logic and highlights the need for automated escalation pathways.
• Device delays: Specifically, delays due to network infrastructure such as Wifi or radio availability are increasingly common as providers use personal devices. If critical alerts can’t override these settings, response times suffer.

‍

Why Most Hospitals Don’t Have Accurate Timing

Despite the importance of these metrics, many hospitals lack the data infrastructure to measure them reliably. Manual logs and paper forms are prone to inaccuracy and often reflect approximations rather than precise timestamps. Switchboard operators may record when they placed a call, but not when the provider actually received or acknowledged it. This fractured system means there’s no unified source of truth, and no way to track micro-delays across the workflow.

This creates a dangerous gap between perceived performance and actual performance. Leadership may believe that code activations are fast and efficient on the surface. In reality, hidden delays at each step of the workflow are quietly eroding outcomes.

‍

Why Current Code Activation Workflows Fail

The root cause of most activation delays isn’t a lack of effort or commitment from clinical teams. Instead, it’s the limitations of the tools they currently use in their clinical workflows. 

‍

Reliance on Pagers and Phone Trees

Pagers are still commonly used in hospitals, but they’re not well-suited for modern emergency response. They add sequential delays because each provider must be contacted individually. There’s no acknowledgment mechanism, no read receipts, and no way to confirm that the alert was received..

Phone trees have similar limitations. Each call must be placed manually, and if the first provider doesn’t answer, the process continues to the next person. 

‍

Manual Switchboard Bottlenecks

Switchboards serve an important function in hospitals, but they weren’t designed for the speed required in emergency code activations. Operators must locate the right provider, often consulting outdated on-call schedules or making judgment calls about who to contact..

Even when switchboard staff perform seamlessly, the manual nature of the process introduces inherent delays. Every second spent looking up a phone number, dialing, and waiting for an answer is time that could be saved through automation.

‍

Fragmented Communication Ecosystems

Perhaps the most subtle source of delay is the fragmented nature of hospital communication systems. When teams rely on a mix of pagers, phones, EHR alerts, and disparate messaging apps, information doesn’t flow seamlessly. Context is lost, escalation logic is missing, and there’s no automatic audit trail to support post-event review.

Siloed tools prevent simultaneous alerting. If a hospital wants to notify the cardiologist, the ICU attending, and the code team all at once, they may have to use multiple systems, each with its own interface and reliability issues. Missing escalation logic means that when a primary responder doesn’t acknowledge an alert, there’s no automatic failover to a backup provider.

Without centralized logging, hospitals can’t accurately measure activation times or identify bottlenecks. They’re forced to rely on approximations and anecdotal reports, which obscure the true performance of their workflows.

‍

How Hospitals Can Reduce Activation Times

Eliminating delays in code activation requires a systematic approach that combines process improvement with modern technology. The goal isn’t incremental gains measured in minutes, but dramatic reductions measured in seconds.

‍

Map the Current Activation Workflow

The first step is understanding exactly how your emergency code activations work today. This means mapping every step, from the moment an emergency is recognized to when all required providers arrive at the bedside. Engage all stakeholders to identify each handoff and micro-delay.

Workflows that leadership assumes are efficient may contain multiple hidden delays that frontline staff have simply learned to accept as normal. By documenting the current state in detail, hospitals create a baseline for measuring improvement and identify the highest-impact areas for intervention.

‍

Automate the Code Activation Process

The most effective way to reduce activation times is to replace sequential alerts with simultaneous notifications. When a code is activated, the entire team should be alerted at once, not one person at a time.

Automation should also include escalation logic. If a primary responder doesn’t acknowledge an alert within a defined timeframe, the system should have a framework to escalate to a backup provider without requiring manual intervention. This eliminates the potential delays that occur when the requesting provider must decide when and how to escalate.

STAT alerts that override silent mode and do-not-disturb settings ensure that critical notifications reach providers. This capability is essential in time-critical scenarios where delays of even a few minutes can be catastrophic.

‍

Streamline Routing With Real-Time On-Call Scheduling

A common source of delay is uncertainty about who’s on call. When on-call schedules are outdated or difficult to access, switchboard operators and clinical staff waste time trying to locate the right provider.

Consolidated on-call scheduling with real-time updates solves this problem by automatically identifying and notifying the correct on-call provider based on the current schedule. This removes guesswork and switchboard dependency, allowing code activations to proceed without the friction of manual lookups.

‍

Centralize All Code Communication Into One Platform

The most effective way to eliminate communication delays is to centralize all code-related messaging, scheduling, escalation, and audit trails into a unified platform.

This doesn’t mean replacing every communication tool in the hospital, but it does mean consolidating the critical workflows that matter most in emergency scenarios. When everything lives in one system, there’s no need to toggle between apps, no risk of missing alerts buried in different inboxes, and no gaps in the audit trail.

A unified platform also makes it easier to implement intelligent escalation logic, priority-based alerting, and real-time visibility into who’s responding and when they’ll arrive.

‍

Track, Audit, and Improve Performance Continuously

Technology alone isn’t enough. Hospitals must commit to ongoing measurement and continuous improvement. Real-time analytics dashboards provide visibility into activation times, acknowledgment rates, and escalation events, allowing leadership to identify trends and address problems before they become systemic.

Automatic timestamps eliminate the need for manual logging and provide an accurate record of every step in the activation workflow. This data is invaluable for post-event reviews, quality assurance, and regulatory compliance.

Perhaps most importantly, regular review of activation metrics creates accountability. When teams know that performance is being measured and reviewed, they’re more likely to follow protocols and escalate issues when delays occur.

Real Results: How Hospitals Improved Their Activation Times

Royal Victoria Regional Health Centre (RVH)

Regional Ontario hospital Royal Victoria Regional Health Centre (RVH) sought to transform its emergency response capabilities across Code STEMI, Code Blue, Code Stroke, Life and Limb activations, and other urgent activations. RVH relied on a traditional switchboard system to manually page interventional cardiology teams – a process that was prone to delays and impeded rapid response. 

The hospital partnered with Hypercare to automate its STEMI activations and improve its hospital emergency response times. The real-time emergency response improvements included one-tap activations, integrated scheduling, automatic escalation mechanisms, and secure ECG transmissions. 

“Activating a STEMI is now seamless,” says Dr. Mark Kotowycz, Interventional Cardiologist & Medical Director, Cardiac Intervention Unit at RVH. “We no longer wait for pages to be returned [and] the entire team is alerted instantly. The faster we mobilize, the sooner we can open the artery, directly improving patient outcomes.”

‍

Mile Bluff Medical Center

Mile Bluff Medical Center experienced similar transformations after working with Hypercare to improve emergency response. The hospital previously had a fragmented communication system that relied on manual calls to the switchboard, inaccessible on-call schedules, and a lack of secure messaging. 

Mile Bluff partnered with Hypercare to improve its clinical communications, which included enabling one-click activation for urgent scenarios, making real-time scheduling accessible, and supporting HIPAA-compliant messaging. 

As a result, activation time for urgent and emergency surgeries dropped from 20-30 minutes to just 5 seconds. The clinical teams also reported dramatic reductions in miscommunication and coordination delays.

“The system eliminated scut work so we could focus on patients,” says Randall Brandt, PA & IT Provider Liaison at Mile Bluff Medical Center. “We no longer waste time figuring out who to call – Hypercare tells us instantly.”

The Bigger Impact: Clinical Outcomes, Safety, and Workforce Relief

Reducing code activation times is critical for better patient outcomes. The downstream effects ripple through every aspect of hospital operations and patient care. Faster activations directly reduce mortality and complications, whether for STEMI or in-hospital cardiac arrests. 

But the benefits extend beyond clinical outcomes. Better coordination through automated, reliable workflows can help lower cognitive load on clinical staff who no longer need to navigate fragmented systems or second-guess whether their alerts were received. Research from a systematic review suggests that reduction in stress and uncertainty can directly combat burnout, particularly for frontline staff such as switchboard operators, rapid response teams, and on-call providers who bear the brunt of communication failures.

Perhaps most importantly, reducing variation in activation workflows creates inherently safer hospitals. When every code follows the same streamlined process with automatic escalation and real-time visibility, there’s less room for human error, missed alerts, or confusion about who’s responding. Standardized, technology-enabled workflows help make hospitals more predictable, more reliable, and ultimately safer for everyone.
