Every day, healthcare practitioners diagnose conditions, explain treatment options, and recommend evidence-based interventions.
The clinical plan may be sound. The patient may leave the appointment intending to follow it.
Then the patient goes home.
Questions surface. Details become harder to remember. A family member raises concerns. A side effect appears. What felt clear inside the exam room becomes uncertain at the kitchen table.
Healthcare has traditionally treated the prescription, treatment recommendation, or discharge conversation as the end of the process. For the patient, however, it is often only the beginning.
A systematic review published in BMC Health Services Research in March 2026 examined one of the variables that may determine what happens next: the quality of communication between patients and healthcare practitioners.
What 24 studies reveal about communication and adherence
The systematic review analyzed 24 studies involving 8,671 patients. Six were randomized controlled trials involving 733 patients, while 18 were observational studies involving 7,938 patients.
The findings were not identical across every study design.
The pooled analysis of the randomized trials found a small positive effect of communication interventions on adherence, but the result was not statistically significant. The researchers also reported substantial variation among the trials and rated the certainty of the evidence as very low.
The observational evidence was more consistent.
All 18 observational studies reported a positive association between effective practitioner communication and improved treatment adherence. Among eight studies that could be combined statistically, better communication had a moderate positive association with adherence.
Communication is not the only factor affecting adherence. But across real-world healthcare settings, patients who report better communication with their practitioners also tend to report better follow-through.
Based on findings from: Keshtkar et al., BMC Health Services Research (2026), “The effectiveness of healthcare practitioners’ communication on patients’ adherence to healthcare recommendations: a systematic review.”
The distinction matters. The review does not suggest that a single scripted conversation can eliminate nonadherence. It suggests that communication is a meaningful, modifiable part of a much larger adherence strategy.
Adherence is not simply an information problem
Many patient support programs are built around the assumption that patients need more information.
They receive printed instructions, lengthy educational materials, portal notifications, automated reminders, and access to centralized support lines.
Those resources may have value. But information alone does not necessarily resolve the uncertainty that develops after the patient leaves the office.
Patients may understand what a medication does and still worry about taking it. They may know a procedure was recommended and still postpone scheduling it. They may receive written instructions and remain unsure whether a new symptom is expected.
The review points toward something more human: communication that builds trust, addresses concerns, clarifies recommendations, and helps patients participate actively in their care.
The researchers identified behaviors such as clear information sharing, empathy, active listening, open-ended questions, and addressing barriers to treatment as important components of effective communication.
Patients do not only need access to instructions. They need enough clarity and confidence to act on those instructions when the practitioner is no longer in the room.

That is where many patient journeys begin to break down.
The practitioner’s voice disappears when the patient needs it most
The challenge is operational.
Practitioners cannot repeat the entire clinical conversation every time a patient has a question at home. They cannot personally call every patient when treatment hesitation develops, when a prescription remains unfilled, or when someone considers stopping therapy.
As a result, the most trusted voice in the patient journey often becomes the least available after the appointment.
The communication is replaced by a portal, a PDF, a call center, or a generic automated message. The patient still receives information, but the authority, familiarity, and reassurance of the treating practitioner may be missing.
This creates a gap between clinical intent and patient execution.
The appointment produces the recommendation. The patient’s home environment determines whether that recommendation becomes action.
Scaling trusted communication beyond the encounter
The systematic review focused on direct patient-practitioner communication and did not evaluate prerecorded videos, SMS education, or other automated messaging formats.
It does, however, raise an important question for healthcare organizations:
If practitioner communication is associated with better adherence, how can the value of that communication continue after the patient leaves?
The answer is not to replace the practitioner with more generic support.
It is to preserve and extend the parts of practitioner communication that patients rely on most: a recognizable clinical voice, clear explanations, empathy, reassurance, and guidance tied to the treatment decision in front of them.
That communication should also reach patients where decisions are actually being made.
Not behind another portal login.
Not inside a document the patient is unlikely to reopen.
It should arrive directly, at the moments when confusion, hesitation, or treatment friction are most likely to occur.
This is where Hoot operates. Hoot helps healthcare organizations extend doctor-led education beyond the clinical encounter through timely video communication delivered directly to the patient’s phone. The goal is not simply to send more content. It is to reinforce the clinical recommendation with a trusted voice when the patient is deciding what to do next.
The practitioner does not need to be physically present at the kitchen table. But the clarity and reassurance of the practitioner’s message should not disappear when the patient gets there.
Communication should be part of the adherence infrastructure
The review’s authors are careful not to present communication as a standalone cure for nonadherence.
Cost, access, side effects, treatment complexity, transportation, health literacy, and personal circumstances can all affect whether patients follow a recommendation.
Communication cannot eliminate every barrier.
But it can help patients understand the plan, express concerns, evaluate uncertainty, and remain connected to the clinical reasoning behind their care.
That makes communication more than a soft skill.
It is part of the infrastructure required to move a patient from recommendation to action.
Healthcare organizations invest heavily in discovering therapies, building access programs, training clinical teams, and creating treatment pathways. Those investments only produce value when patients begin and continue the care being recommended.
The clinical encounter may be working.
The next opportunity is to make sure the communication continues long enough for the treatment plan to work too.
