Introduction

In healthcare, word-of-mouth often works as an invisible but decisive growth mechanism. Particularly in high-trust domains, patients do not make decisions based only on advertising or corporate visibility; they pay attention to the experiences of other patients. For this reason, a recommendation in healthcare is not only an indicator of satisfaction but a strategic variable for patient acquisition and retention.

But a critical question arises: what actually pushes patients to recommend a provider to others? A technically successful treatment, or the quality of the relationship and follow-up sustained after treatment? Research findings show that technical competence is necessary but does not, by itself, explain the spread of word-of-mouth. The experience the patient narrates is often shaped less by the clinical outcome itself and more by how they were made to feel throughout the process.

1. How Effective Is Word-of-Mouth in Healthcare?

The impact of recommendations in healthcare is stronger than in many other sectors. In a Romania-based family medicine study, 84% of patients consulted other patients' recommendations when choosing a physician, and 97.9% said they would recommend the service they received to family and friends. Larger national surveys show a similar picture: 50% of consumers use word-of-mouth recommendations when choosing a doctor or clinic. Notably, the same study shows that online data and official quality indicators are used only 2.5–11% of the time. This finding doesn't mean transparency data or digital content is ineffective — it means that in healthcare decisions, reliable human experience still works more powerfully.

Press Ganey's 2023 trends offer an important distinction as well. Patients increasingly turn to digital sources for health information, but the strongest driver of loyalty and five-star reviews remains the quality of customer service. In other words, information-gathering is digitalising; but trust-building and recommendation generation still move through an experience-centred process.

2. What Actually Triggers WOM: Technical Quality or Communication?

At first glance the answer seems to be technical quality. Clearly, a poor clinical outcome does not produce long-term recommendations. However, the literature shows that positive recommendation is not formed merely along the "the treatment went well" line. In a Springer-published literature review of WOM in healthcare, empathy, communication skills and consultation time strongly influence recommendation behaviour. Even though technical skills are important, the experience the patient conveys to others is usually shaped around how much the physician explained, listened and built a relationship.

"Good treatment can be the foundation of a recommendation; but what triggers the recommendation is often the patient's sense of being safe, understood and guided."

Findings specific to dental clinics make this distinction sharper. In a study of 964 patients, the strongest predictor of patient loyalty was the dentist's explanation of treatment options. The item receiving the highest satisfaction score was the dentist carefully listening to the patient. This is a highly important result: the element that most strongly feeds patient loyalty and, by extension, recommendation behaviour is often not the technical detail itself, but how that detail is conveyed.

The conclusion is clear. Good treatment can be the foundation of a recommendation; but what triggers a recommendation is often the patient's sense of being safe, understood and guided.

3. Why Is the Cost of Negative Word-of-Mouth So High?

The value of word-of-mouth is understood not only through its positive side, but also through the magnitude of its negative impact. Review data shows that a dissatisfied patient shares their experience with an average of 15 people. More importantly, a single negative review can influence 5 to 10 potential patients. Given that decisions in healthcare are made under high perceived risk, the commercial translation of this effect is substantial.

Assessments based on Medical Economics show that negative word-of-mouth can cause up to $400,000 of lifetime value loss for a hospital or health system on a single patient basis. Dental Economics data reports that communication breakdown can lead to annual losses of $160,000 to $2 million in dental clinics. The same source notes that a single dental patient, combined with referrals, can carry a total lifetime value of $60,000.

Therefore, negative WOM is not just a reputation problem. It means measurable patient loss, revenue loss and growth loss. When experience deteriorates in healthcare, the damage is not limited to the existing patient; it extends to the future pool of patients that may have come.

4. Why Do Patients Really Leave?

The reason for patient loss is often neither price nor clinical outcome. One of the most striking findings in research reviews is that 68% of patients' reasons for switching providers is explained by a "perception of indifference." Price at 9% and service complaints at 14% show that the real break happens at the emotional and relational level.

A technically correct treatment, when combined on the patient's side with indifference, coldness, late response, uncertainty or a feeling of being left alone, may not produce loyalty. In fact, even when the clinical outcome is strong, the patient may move to another institution for their next need. This is because although patients cannot evaluate every detail of medical success, they clearly sense how they are treated.

At this point, the post-treatment period becomes decisive. Narrative reviews show that in dental services, the factors affecting return visits are not limited to pre-treatment access and in-treatment communication; post-treatment follow-up, continuity of care and payment transparency are also strong determinants.

5. Why Is Good Follow-Up Critical to Generating WOM?

Word-of-mouth often forms after treatment. When the patient leaves the clinic, they enter not only a recovery process but also a narrative-building process. This narrative either remains limited to "the procedure was successful" or turns into a stronger, more shareable experience like "they were attentive at every step, explained what I needed to do, followed up."

Beryl Institute's 2024 data shows that positive experiences strengthen long-term relationship and loyalty; negative experiences trigger the search for alternatives. The same report emphasises that patient experience directly affects future healthcare choices. This means follow-up experience is critical not only for current case management but also for the future referral pipeline.

A qualitative study in Indonesia reaches a similar conclusion: the patient–provider relationship plays a decisive role in revisit intent. Trust and emotional factors affect both satisfaction and return behaviour. Good follow-up operationalises this trust. Timely response to the patient's questions, uninterrupted follow-up communication, handling small complaints before they escalate, and not leaving the patient with a sense of "the procedure is over, the file is closed" all strengthen the positive narrative.

Conclusion

The real trigger of word-of-mouth is not a single variable that fully separates good treatment from good follow-up. Without technical quality, it is impossible to produce strong and sustainable recommendations. However, research shows that what actually activates recommendation behaviour is often not the technical success itself, but how that success is translated into patient experience.

Patients value expertise and outcomes. But what they tell others is usually not the technical details of the treatment; it is how clearly it was explained, how they were listened to, how quickly they received responses when they had issues, and whether they were left alone after treatment. That is why WOM in healthcare often starts with "good treatment" — but spreads through "good follow-up."
