Brand Promise vs Patient Experience: How to Audit the Gap

Every message is a promise

A hospital website says care is personal. A billboard says waits are short. A social post says the new wing is calm and modern. Each of these is a brand promise. Patients read them before they arrive, and they compare them with what they find.

When the two match, trust grows. When they do not, the gap does more damage than a modest message would have done. The work is to find those gaps before patients do, and to know which side to fix.

What the gaps model says

The model. In 1985 Parasuraman, Zeithaml and Berry published a conceptual model of service quality in the Journal of Marketing, built from research in four service businesses. It describes a chain of gaps inside the provider that together shape the gap the customer feels: the distance between expected and perceived service.

Gap 4 is the communication gap. The fourth gap sits between service delivery and external communications. It opens when advertising, sales and public statements say one thing and the service does another. Later teaching of the model summarises it as not matching performance to promises.

Promises have three parts. Mary Jo Bitner, a services marketing scholar at Arizona State University, describes a triangle. The organisation makes promises to customers. It enables them through staff, systems and processes. Staff keep them in each encounter. In her words, "services is all about promises." A promise that the organisation has not enabled is a gap waiting to appear.

It applies to hospitals. Babakus and Mangold tested SERVQUAL, the measurement scale that grew out of the gaps model, in hospital services. Both the expectations and perceptions versions met several reliability and validity criteria. The framework is not only for banks and retailers.

Healthcare messages often overreach. Larson and colleagues reviewed 122 patient-facing print ads from 17 leading US academic medical centres in 2002. Emotional appeals were the most common strategy. Almost every ad for a specific service left out potential harms, and no centre had a formal process to review its ads for balance.

Patients describe what surveys miss. Ranard and colleagues analysed 16,862 Yelp reviews of 1,352 US hospitals. They found 12 domains of experience that the national HCAHPS survey does not cover, including cost, billing, staff compassion and the care of family members. That is where many silent issues hide.

How to run a patient experience audit

A brand audit in healthcare does not need a large team. It needs a clear method and the discipline to keep every finding tied to its source.

1. Inventory your public promises. Collect what the institution says in public: website pages, advertising, social posts, brochures, signage, press statements. Rewrite each as a testable claim, with its date and link. "Excellence in care" is hard to test. "Results within 24 hours" can be tested. Note which promises are explicit and which are implied by images or tone.

2. Collect public experience signals. Gather what people say in public: reviews on major platforms, public posts that mention the institution, published complaints data, press coverage. Keep the source link for every item. Study topics across many posts. Do not profile, track or contact individual writers. Read what patient reviews can and cannot tell a hospital before drawing conclusions from them.

3. Match them claim by claim. Group both sides under the same themes: waiting, communication, cleanliness, billing, outcomes, compassion. For each promise, list the public signals that support it, the ones that contradict it, and how many there are. A claim with three contradicting posts and no supporting ones is a question, not a verdict.

4. Classify each gap. Three patterns matter most.

• Overpromise. You promise something that public experience consistently contradicts. This is the gaps model's fourth gap.
• Unseen strength. People praise something you never mention. The service is ahead of the message.
• Silent issue. People raise a topic your messages never address, such as billing or parking. Nothing was promised, but expectations formed anyway.

Some claims will have too little evidence on either side. Label them insufficient evidence and leave them open.

Fix the service or fix the message

Each gap leads to one of two decisions, and sometimes both. Our own view is that reality makes the image. So when both fixes are possible, we start with the service and bring the message in line afterwards, with evidence. A message cannot carry what the service does not do.

Fix the service when the promise is right and worth keeping. If the institution wants to be known for short waits, the answer to an overpromise is shorter waits, with a named owner and a date. Bitner's triangle helps here: ask which part of the system failed to enable the promise.

Fix the message when the promise cannot be kept soon, or should not have been made. Replace vague superlatives with specific, checkable statements. Say what the service does, not what it feels like. For an unseen strength, start saying it, with evidence.

Consider a hypothetical example. A clinic's website promises same-day appointments. Public posts over six months describe waits of a week for new patients, while returning patients report same-day slots. The honest fix may be both: change the message to state what applies to whom, and review how new-patient capacity is planned.

Make it a quarterly habit

Promises change with every campaign. Public experience changes with every season. A single audit goes out of date quickly.

• Repeat the audit every quarter, using the same themes so results can be compared.
• Log every gap, the decision taken, the owner and the date it was closed.
• Review new campaigns against the gap log before they are published.
• Report trends inside your own institution before comparing with anyone else.

Keep the limits in view. Public posts come from people who chose to write. They do not represent all patients, a community or a country. The audit shows where the public record and the institution's message disagree. It does not prove what every patient experienced. When evidence is thin, say so.

How Mirror supports the audit

Mirror reads what an institution publishes and what people say about it in public, then shows each gap with its public source beside it. It groups themes across many posts rather than following individuals, and it marks where evidence is too thin to support a conclusion. Your team decides what to fix and what to say.
