An abnormal cervical cancer screening result is not the end of the care journey. For many patients, it begins another series of appointments, tests, procedures, or treatment. But recommending follow-up care does not guarantee that a patient can access it.

A recent study of an inpatient cervical cancer screening program found that more than half of patients who needed follow-up did not return for care. It also identified a meaningful association for healthcare organizations working to improve access: patients with documented transportation assistance had nearly three times higher odds of returning for follow-up care. Transportation was not the only factor affecting these patients. The study population faced complex barriers, including housing instability and substance use. Because the study was observational, the findings show an association between transportation assistance and follow-up, not proof that transportation caused the improvement.

Still, the broader evidence suggests transportation support deserves attention. A systematic review of 12 studies found that non-emergency medical transportation interventions were associated with fewer missed clinic visits. Its meta-analysis of seven studies also found lower odds of missed appointments among patients receiving transportation interventions. That review included a randomized trial of 2,044 women with abnormal cervical cytology. Participants who received bus tickets alongside a follow-up reminder had higher adjusted odds of returning for care than those who did not receive the transportation incentive.

The question for healthcare organizations is not simply whether patients have a need for transportation. It is whether systems are in place to help patients return when the next stage of care requires them to do so.

The Follow-Up Gap Is an Access Gap

Healthcare organizations have made significant investments in screening, early detection, patient navigation, and care coordination. But those investments reach their full potential only when patients can continue through the next stage of care. For a patient with an abnormal screening result, follow-up might require another clinic visit, diagnostic testing, a specialist appointment, or a procedure. Each step creates another access point that has to work.

Insurance coverage and an established relationship with a provider do not eliminate every barrier. Research on cervical cancer screening has identified nonfinancial obstacles, including transportation, awareness, health literacy, beliefs, and service quality, that can still affect whether patients receive care.

Transportation can become particularly important when patients need to travel repeatedly, live farther from care, cannot drive following a procedure, or require specialized transportation such as wheelchair, stretcher, bariatric, or ambulatory assistance. In these situations, transportation is not simply about getting someone from one location to another. It is part of the infrastructure required to keep the care journey moving.

Identifying a Barrier Is Only the First Step

Healthcare organizations increasingly have tools to identify the social and logistical barriers affecting their patients. The next challenge is turning that information into action. Knowing that a patient has a transportation need is different from having the infrastructure to resolve it.

Effective transportation coordination may require matching a patient with the appropriate vehicle and mobility support, coordinating transportation around appointment and procedure requirements, supporting recurring or long-distance trips, providing visibility into ride status, responding when plans change, and tracking ride outcomes alongside broader access goals.

This is where transportation moves from a reactive service to an operational component of patient access.

Missed Appointments Begin Earlier

When a patient does not return for follow-up, healthcare organizations see the final outcome: a missed appointment. But the access breakdown may have occurred much earlier. Transportation may never have been arranged. Available transportation may not have accommodated the patient’s mobility needs. An appointment may have changed without the ride changing with it. A transportation provider may no longer have been able to fulfill the trip. Or the patient may not have had a reliable way to cover the required distance.

Research on follow-up after breast and cervical cancer abnormalities points to the same operational challenge: barriers may be identified early, but they do not always resolve after one interaction. In a patient-navigation study, most barriers were identified during the first navigator encounter, while health-system scheduling problems were the barrier most likely to recur.

That makes follow-up access an ongoing coordination challenge, not a one-time referral, reminder, or ride request. Rather than measuring only who did not return, organizations can examine where access broke down and where intervention may be possible.

Transportation Data Can Become Access Data

Transportation also creates another source of information about the patient journey. Ride completion, mobility requirements, travel distance, geographic patterns, transportation disruptions, and patient feedback can all provide insight into how patients access care.

That information enables more meaningful questions than simply whether a ride was scheduled:

  • Did the patient reach care?
  • Where do transportation barriers occur most frequently?
  • Which patients require additional mobility support?
  • Where are transportation challenges repeatedly disrupting care?
  • Which interventions are helping patients remain connected to care?

Measuring these operational signals helps distinguish between a scheduled ride and a completed care connection. A ride may be arranged, yet a changed appointment, an unmet mobility requirement, or a provider cancellation can still prevent the patient from receiving care.

The evidence is strongest for the relationship between transportation support and fewer missed visits. Research has not yet established firm conclusions about the effects of these interventions on total cost of care, broader utilization, or clinical outcomes. That makes local measurement especially important.

Transportation should be measured not only as a logistical activity, but as one component of a broader access strategy.

Access Must Continue Beyond the First Appointment 

The cervical cancer screening study reinforces an important reality: reaching the first appointment is not enough. Screening may lead to diagnostics. Diagnostics may lead to treatment. Treatment may require recurring appointments. Rehabilitation requires return visits, and chronic conditions require ongoing care.

Transportation will never be the only factor determining whether patients complete those journeys, and the study itself demonstrates how complex patient barriers can be. But the association between transportation assistance and follow-up is significant enough to warrant attention. For healthcare organizations, the opportunity is to build transportation into the care pathway earlier, identify where mobility barriers occur, and create systems that respond when transportation becomes an obstacle to care.

Access is not complete when care is recommended. It is complete when patients can reach the care they need.

The MedHaul Perspective

At MedHaul, we believe medical transportation should be treated as a measurable component of healthcare access. Our platform helps healthcare organizations coordinate transportation across mobility needs while providing visibility into the transportation journey and the data surrounding it.

The goal is bigger than completing rides. It is helping healthcare organizations build transportation systems that support patients throughout their care journey.
