These patterns can create challenges across the care continuum. For practice leaders, it may be more difficult to preserve specialist access, coordinate care across settings, and keep patients connected within the system. Meanwhile, PCPs may lose opportunities to build trust and guide the patient journey, and cardiologists have to spend valuable capacity on diagnostic workups that could have started earlier. As referral volumes rise, specialists may need to spend significant time determining whether a cardiovascular condition is present at all, contributing to longer wait times, repeated testing, and reduced specialist availability.

Rather than immediately referring patients to cardiology, leading organizations equip PCPs with diagnostic tools, clinical workflows, and specialist support to gather more information before escalating care to cardiology. This approach helps PCPs determine whether a cardiovascular condition is likely present and whether specialty involvement is warranted.

As a result, PCPs can take a more active role in evaluating CV concerns, cardiologists receive more targeted referrals, and patients reach the appropriate level of care sooner. When PCPs help identify potential issues and guide next steps, they are also better positioned to build trust with patients and remain the coordinator of care throughout the CV journey.

Under these time and capacity constraints, referrals can become the most practical next step, even when additional evaluation in primary care may be appropriate. But that decision carries downstream impact: specialists often have to conduct additional workup to gather information and better understand the underlying issue — which can contribute to longer wait times, repeated testing, and fragmented care.

Change management is often hard, with existing referral pathways deeply ingrained and difficult to implement. As diagnostic testing expands beyond specialty settings, organizations must establish processes to ensure results are received, reviewed, routed, communicated, and acted upon appropriately. Manual workflows, multiple handoffs, and disconnected systems can create opportunities for delays and errors. Sustaining diagnostic programs often requires a dedicated champion for oversight, clearly defined responsibilities, and workflows that reduce administrative burden while ensuring patients don’t fall through the cracks.

Leading organizations are expanding ambulatory rhythm monitoring beyond cardiology clinics and into primary care, urgent care, and emergency departments. By collecting rhythm data earlier in the patient journey, clinicians can begin evaluating patients closer to the time of symptom presentation and better determine which patients warrant specialty involvement, which can continue to be managed by PCPs, and which may require evaluation for noncardiac causes.

Many organizations are prioritizing these efforts based on referral patterns, wait times, and other indicators of specialty demand, helping direct diagnostic resources where they can have the greatest impact. While these approaches are often discussed in the context of value-based care, they can also benefit organizations operating in fee-for-service environments. For example, reducing unnecessary specialist visits preserves access for higher-acuity patients. Earlier detection can also surface findings that drive appropriate downstream utilization, and PCPs can earn trust to keep patients connected to the system over time.

Successful programs don't expect PCPs to become cardiologists. Instead, they create clear pathways for consultation, education, and shared decision-making. Many organizations support PCPs through regular specialist outreach, webinars, newsletters, physician champion programs, and direct communication between primary care and cardiology leaders. Some also address capacity directly by prioritizing manageable panel sizes or automating administrative work. These organizations recognize that PCPs can only stay engaged in the diagnostic process when they have the capacity to follow patients over time.

Medical directors, physician champions, and specialists can further support PCPs by helping them understand which patients should be monitored, how to use monitoring technology, what findings warrant escalation, and when specialty involvement is appropriate. The goal is to help PCPs narrow the problem before referral while ensuring specialists receive patients with a clearer clinical question.

As diagnostic programs expand upstream beyond specialty care, organizations often rely on nurse navigators, care coordinators, and other dedicated staff to maintain continuity across the diagnostic process. These roles can also help work around panel-size constraints. By absorbing some of the tracking and follow-through that PCPs managing large panels cannot realistically sustain, navigators allow physicians to stay engaged in the workup without adding to their visit load.

Additionally, navigator and coordinator roles become increasingly important as patients move between primary care, specialty care, urgent care, and emergency settings, since responsibility for next steps can become unclear. By providing consistent oversight of testing, results, and patient communication, these teams help ensure potential findings don't fall through the cracks. Without clear ownership, delays in review and follow-up can undermine the value of the program.

As organization gained experience, they adjusted patient selection criteria, modified monitoring approaches, and redesigned workflows. For example, some organizations found that certain monitoring strategies created substantial operational burden without meaningfully changing management decisions, while others discovered that manual report routing and disconnected EHR systems became major barriers to scale. Rather than treating implementation as complete once technology is deployed, leading organizations continually refine workflows to improve efficiency and reduce administrative burden.
