How to Evaluate a Heart Surgery Team's Results? International Heart Care Center Evidence Check Guide

When preparing for heart surgery, seeing introductions such as "experienced," "top-ranked," or "high success rate," the most useful next step is to ask clearly: which surgery do these claims correspond to, which patients, what time period, and how are the results defined.

This article provides general methods for verifying data to help patients and families prepare questions for the potential treatment team. Currently, there is no International Heart Care Center team information or results report available for verification in this article, so it cannot confirm its surgical volume, ranking, success rate, or level of care, nor does it recommend or negatively evaluate it. When verifying data, first confirm the official institution, campus, and team corresponding to the name, to avoid mixing information from different entities.

Turn team claims into questions related to the surgery you are considering

"Experienced team" lacks a clear target for evaluation. During communication, start with the specific procedure the doctor is discussing, and turn promotional statements into questions that can be verified.

• What surgery does the experience in the introduction correspond to? Is it consistent with my planned procedure?

• Do the data belong to the entire hospital, a certain department, or the team that actually receives and performs the surgery?

• Who is expected to be responsible for the surgery, who is responsible for perioperative management, and have there been changes in team members?

• Is there a complete report that specifies the statistical caliber, time range, and source?

If the treatment plan has not been determined, you can first ask the doctor to write down the name of the plan under consideration and the basis for selection, and then verify relevant experience. Promotional content that cannot be matched to a specific procedure for the time being can be kept as background information and should not be used directly to judge personal expected outcomes.

Distinguish hospital total volume, team experience, and specific procedure volume

Hospital total surgical volume, team cumulative experience, and volume of a certain procedure answer different questions. The total volume of the entire hospital cannot directly indicate how many planned surgeries a certain doctor has performed; the number of surgeries a doctor has participated in also needs to distinguish between primary surgeon, assistant, and other roles.

You can verify in the following order:

1. Clarify the subject: Do the data belong to the hospital, campus, department, fixed team, or individual.

2. Clarify the item: Are all heart surgeries, a certain type of surgery, or a specific procedure being counted.

3. Clarify the time: Is it the cumulative number over the career, or the number in the most recent complete statistical cycle.

4. Clarify the unit: Is it the number of patients or the number of surgeries, and how are multiple surgeries for the same patient counted.

5. Clarify the association: Do the personnel and facilities in the data correspond to the team currently providing services.

Data of different scopes are not necessarily contradictory, but cannot replace each other. If the data only provide cumulative totals, you can ask the team to supplement recent, similar procedure data with clear responsibilities.

Ask about the population, time, and follow-up scope covered by outcome data

"Success rate" only has room for interpretation after the definition is clear. Completion of the planned operation, survival at discharge, and health status during the follow-up period are different observed outcomes and cannot be summarized with just one word.

When seeing any proportion, you should look for three pieces of information at the same time: what happened, in how many people it happened, and how long it was observed. You should also confirm whether all eligible patients in the statistical period are included, and which patients are excluded.

The time range of outcome records especially needs to be asked clearly. Recording only the situation during hospitalization and recording the situation for a period after discharge have different coverage. If the report involves follow-up, you should further ask:

• How many people were originally planned for follow-up, and how many actually completed it?

• Was follow-up conducted through outpatient visits, telephone, or other means?

• How are patients who cannot be contacted or transferred to other hospitals handled?

• Is the observation duration consistent for different patients?

Incomplete follow-up means some outcomes are unknown and cannot automatically be treated as no problems occurring. The absence of a reported outcome in the data also does not mean that outcome never occurred.

Why different patient risks affect outcome comparison

To compare the outcomes of two teams, first determine whether the populations they treat are comparable. If one report mainly includes elective, first-time patients undergoing a certain procedure, and another report includes emergency, reoperation, or patients undergoing multiple procedures, directly comparing the raw proportions may be misleading.

These are population differences that need to be verified, and individual risk cannot be inferred based on any single factor. Which factors are relevant to the planned procedure should be explained by the attending doctor based on medical records.

When encountering "risk-adjusted outcomes," you can ask further: what method was used, what factors were included, what population it applies to, and what differences were not covered. Risk adjustment aims to consider recorded population differences, but it cannot be understood as eliminating all factors that affect the comparison.

Similarly, the team's overall outcome describes a group of patients. It cannot be directly converted into an individual patient's probability of success, nor can it replace individualized assessment.

Use a checklist to examine data sources and missing information

You can put public materials and team responses together, item by item record "confirmed," "to be explained," or "temporarily unverifiable." The focus is not collecting more promotional pages, but finding data that can be traced back to the same statistical caliber.

• Source: Are the numbers from original reports, registry data, promotional pages, or oral introductions? Can you view the complete content?

• Subject: Are the institution, campus, department, and team names clear?

• Date: When was the data published, and what period is actually counted?

• Denominator: How many patients or surgeries are included, and are there exclusion conditions?

• Definition: How are results such as success, complications, reintervention defined separately?

• Completeness: Is the method for handling missing records, loss to follow-up, and transfer to other hospitals explained?

• Verification: Who compiled the data, and is the verification process and its coverage explained?

• Uncertainty: Is the fluctuation range, statistical limitations, or situations that cannot be compared reported?

Having only percentages without numbers of people makes it difficult to judge the stability of the numbers; having only conclusions without statistical caliber makes it difficult to confirm to whom the conclusions apply. If there are different numbers in multiple materials, first check whether the time, subject, and denominator are consistent, and then ask the team to explain the differences.

Surgical volume, ranking, and success rate cannot alone prove individual benefit

Surgical volume describes the number of services, ranking reflects the results under a certain set of evaluation rules, and success rate reflects the proportion under a specific definition and observation scope. They all only answer partial questions.

When looking at rankings, you should verify the evaluation year, participation scope, evaluation object, and indicators. Comprehensive rankings may not answer the team performance for a specific procedure, nor can they replace verification of the personnel and outcome reports.

For individuals, it is also necessary to discuss with the doctor: why surgery is considered, what alternative options are available, what problems are expected to be improved, what are the main risks, and what situations may not be suitable for a certain plan. When it comes to specific treatment, contraindications, adverse reactions, drug interactions, and follow-up management requirements should all be explained in the context of the actual plan, not derived from institutional promotional numbers.

Lack of public data does not directly prove poor team performance; publishing pretty numbers does not mean the data are complete, comparable, or independently verified. The conclusions that can be drawn should be consistent with the scope of evidence that can be verified.

Have the prospective team provide written explanations for items that cannot be verified

Before consultation, you can prepare a one-page list of questions, attach the titles, publication dates, and corresponding numbers of relevant materials, and ask the team to reply item by item. Written explanations help preserve the statistical caliber and facilitate verification in subsequent communication.

You can make a request like this:

"Please explain the recent number of cases related to the planned procedure, statistical time, patient inclusion scope, main outcome definitions, and follow-up completion. If risk-adjusted outcomes are provided, please specify the method used and scope of application. For items that are temporarily unavailable or cannot be provided, please also mark clearly."

After receiving the response, focus on whether it explains the original gaps. Items that still cannot be verified should be retained as unknown, not self-completed, and institutional quality or individual outcome should not be inferred based on a single number. For further judgment, you can bring medical records, the proposed plan, and these responses to seek independent opinions from relevant professional doctors.
