Stroke Care Gaps: Why the Hardest Decisions Happen Around the Protocol 

If acute stroke care had a stopwatch, where would it keep stalling? 

Not always inside the science. Not always inside the protocol. Often, it stalls in the minutes around them: unclear onset, late arrival, borderline symptoms, transfer friction, imaging uncertainty, and the handoff after discharge. 

Stroke care is one of the most time-sensitive areas of medicine. Acute ischemic stroke pathways are built around rapid recognition, imaging, thrombolysis eligibility, thrombectomy access, and secondary prevention. The evidence is strong. The protocols are widely known. Yet the real-world pathway is rarely as clean as the guideline diagram. 

MDForLives survey data from neurologists shows that the most important stroke care gaps are not simply about knowing what to do. They are about whether patients, hospitals, transfer networks, imaging workflows, and follow-up systems allow the right decision to happen in time. 

The Thrombolysis Window Is Often Lost Before the Hospital Can Act 

The first gap appears before the hospital pathway begins. 

In the survey data, only 5.0% of neurologists said more than 75% of suspected ischemic stroke patients reach them within the IV thrombolysis window. The largest group, 40.0%, said only 25% to 50% arrive within the window, while 26.2% said fewer than 25% do. 

This is a powerful signal. A fast door-to-needle workflow matters, but it cannot recover time already lost before arrival. 

When neurologists were asked why otherwise-eligible patients most often miss thrombolysis, 58.8% selected late patient arrival, while 37.5% selected unclear onset or wake-up stroke. 

That means the thrombolysis gap is largely upstream. It is shaped by symptom recognition, emergency response, patient hesitation, wake-up stroke ambiguity, geography, routing, and the timing of first clinical contact. 

The insight is clear: one of the biggest stroke care gaps begins before the neurologist sees the patient. 

Borderline Cases Are Not Exceptions. They Are Daily Practice. 

Textbook stroke pathways work best when onset is clear, deficits are obvious, imaging is straightforward, and risk is easy to frame. But neurologists frequently work outside that ideal. 

In the survey data, 46.2% said borderline cases often create uncertainty in thrombolysis decisions, and 8.8% said very often. Another 41.2% said sometimes. Only 3.8% said rarely. 

These cases may involve mild but potentially disabling deficits, wake-up stroke, unclear onset, rapidly improving symptoms, anticoagulation, posterior circulation ambiguity, or uncertain functional impact. 

This matters because borderline cases consume time differently. The decision is not only “eligible or ineligible.” It becomes: how much uncertainty is acceptable, how disabling is the deficit, what does imaging suggest, what is defensible, and how much time remains? 

Stroke care gaps are often widest where the patient does not fit the clean pathway. 

Guidelines Anchor Decisions, but Judgment Still Carries the Edge Cases 

Neurologists are not abandoning guidelines. The data shows a more nuanced pattern. 

About 47.5% said thrombolysis decisions are mostly guideline-driven. Another 48.8% said decisions are balanced between guidelines and clinical judgment. Only 3.8% said decisions are mostly driven by clinical judgment. 

This suggests that guidelines remain the anchor. But the real work often happens at the edge of certainty. 

Clinical judgment becomes important when evidence does not map neatly onto the patient in front of the team. A guideline may define thresholds. The neurologist still has to interpret disability, risk, imaging ambiguity, comorbidity, patient history, and urgency. 

Neurological decisions rarely depend on a single guideline or test. Clinical history, examination, imaging, biomarkers, and patient context all need to be interpreted together. Explore what really drives decisions in modern neurology.

The challenge is not guidelines versus judgment. The challenge is building stroke systems that support judgment under time pressure. 

Thrombectomy Delays Are Network Problems, Not Just Hospital Problems 

For large vessel occlusion patients, the main barrier to timely mechanical thrombectomy was inter-hospital transfer delay, selected by 40.0%. Limited thrombectomy-capable centers followed at 25.0%, while imaging and triage delays were selected by 16.2%. 

This shows that thrombectomy is not a single-site sprint. It is a network relay. 

Eligibility may be clear, but speed depends on where the patient presents, how quickly large vessel occlusion is suspected, whether vascular imaging is available, how transfer decisions are made, whether a thrombectomy-capable center has capacity, and how transport is coordinated. 

These are not small operational details. They determine whether evidence-based treatment remains realistically available. 

For thrombolysis, the challenge is often arrival within time. For thrombectomy, the challenge is often moving the patient through the right network fast enough. 

Imaging Is Not Always the Bottleneck, but Certainty Still Takes Time 

Imaging rarely causes delays for 51.2% of neurologists in the survey data. That is encouraging. It suggests baseline imaging access is often functioning. 

But for the remaining respondents, delays appear around advanced imaging and interpretation: MRI delays were selected by 18.8%, CTA access by 13.8%, radiology turnaround time by 11.2%, and CT scanner availability by 5.0%. 

This pattern matters. The bottleneck is not always the scanner. Sometimes it is the need for added certainty. 

Wake-up stroke, posterior circulation suspicion, extended time windows, mild deficits, or unclear onset may require more than a simple scan. The decision slows when the team needs to determine whether treatment remains beneficial, safe, and defensible. 

In practice, imaging is both a tool and a threshold. It helps resolve uncertainty, but when uncertainty is complex, imaging workflows must be designed for speed as well as accuracy. 

Hemorrhagic Stroke Outcomes Depend on Readiness 

For hemorrhagic stroke, the leading factor limiting optimal outcomes was late presentation, selected by 42.5%. ICU or critical care availability followed at 20.0%, access to reversal agents at 17.5%, blood pressure control challenges at 11.2%, and limited neurosurgical access at 8.8%. 

This shows that hemorrhagic stroke outcomes are shaped by readiness. 

The first issue is still time. But after arrival, outcomes depend on whether critical care capacity, reversal workflows, blood pressure protocols, and neurosurgical access are available when needed. 

The decision may be clinical, but the outcome depends on system preparedness. 

Prevention Breaks After Discharge 

Stroke care does not end when the patient leaves the hospital. In many ways, that is where another major set of stroke care gaps begins. 

When neurologists were asked the most common reason for recurrent stroke in previously treated patients, 45.0% selected suboptimal risk factor control, and 26.2% selected poor medication adherence. Unclear or mixed etiology followed at 16.2%, while inadequate follow-up was selected by 8.8%. 

This finding is important because acute stroke care is structured. Post-discharge prevention is lived in the real world. 

Patients need blood pressure control, lipid management, diabetes care, anticoagulation or antiplatelet adherence when appropriate, lifestyle support, follow-up, education, and clarity on stroke etiology. But outside the hospital, these steps depend on continuity, access, patient understanding, affordability, family support, and primary care coordination. 

Neurologists were only moderately confident in this handoff. About 57.5% said they were moderately confident that patients would receive intended secondary prevention and follow-up, while 10.0% were slightly confident and 2.5% were not confident. 

That means prevention is not only a prescription issue. It is a continuity issue. 

Where Guidelines Feel Least Complete 

When asked what stroke guidelines fail to adequately address in real-world practice, 32.5% selected borderline and uncertain cases. System and transfer delays followed at 23.8%, and post-discharge continuity of care at 17.5%. 

This is the strongest synthesis of the survey. 

Neurologists are not saying the core science is weak. Only 1.2% selected first-line thrombolytic therapy as the main guideline gap. The concern is implementation under real-world conditions. 

Guidelines work best when timing is known, resources are available, pathways are aligned, and follow-up is reliable. The hardest stroke care gaps appear when those conditions break down. 

Closing Perspective 

Stroke care does not fail only at the point of treatment. It can fail before arrival, during transfer, at the edge of eligibility, inside imaging workflows, in hemorrhagic stroke readiness, and after discharge. 

MDForLives survey data suggests that neurologists are working in a pathway where science is strong, but execution is fragile. The problem is not simply whether protocols exist. It is whether the system is built for the real situations neurologists face every day. 

Unclear onset. Borderline deficits. Transfer delay. Variable imaging access. ICU capacity. Reversal availability. Medication adherence. Risk-factor control. Follow-up continuity. 

These are not peripheral issues. They are where the pathway becomes real. 

The next improvement in stroke care may not come only from refining the guideline. It may come from designing systems around the moments where guidelines meet uncertainty. 

Because for stroke, the difference between precision and pressure is often measured in minutes, handoffs, and what happens after the patient leaves the unit.
