[Direct answer]In the Beijing area, the circumstances that may lead to liability include: failing to conduct key examinations that should have been done (such as not taking a CT scan or performing a biopsy); failing to review or inform patients of abnormal examination results; and omitting the main disease when multiple diseases coexist — that is, a missed diagnosis due to a failure to fulfill the diagnostic and treatment obligations corresponding to the medical level at that time, which results in delayed treatment and harm to patients. In such cases, the hospital shall compensate according to the proportion of its fault; however, if the disease itself is hidden or the examination methods at that time are difficult to detect the disease, it constitutes a reasonable medical limitation and does not constitute a fault.

1. Problem background and typical scenarios

Here are the translations of the above text into English: A typical scenario of misdiagnosis: The physical examination report shows abnormal indicators, but the attending doctor fails to suggest a follow-up examination, and the patient is diagnosed with advanced cancer a year later; A trauma patient undergoes an X-ray but not a CT scan, missing fractures or organ injuries; Two diseases coexist, but only the one causing the main complaint is treated; The referral and follow-up chain is broken, and abnormal results remain unattended in the system. The harm of misdiagnosis is that "time is stolen" - there is a huge gap between early detection and late detection in terms of treatment options and prognosis.

II. Key points of contention

First, the determination of the fault of misdiagnosis. The four-level screening of examination obligations, interpretation obligations, notification obligations, and follow-up obligations. Second, causality and causative force. The impact of delay on prognosis and the impact of the disease's own progress. Third, the allocation of responsibility for multiple visits. The division of responsibilities between the initial diagnosis hospital and the re-diagnosis hospital. Fourth, the quantification of damage. Scientific evaluation of survival period differences, treatment cost differences, and loss of labor capacity.

III. Professional analysis by Henglue Lawyers

The responsibility review for misdiagnosis cases is conducted according to the "four-level obligation screening - appraisal and determination of responsibility - proportional compensation" process. **First-level obligation screening**: - **Examination obligation**: Check whether necessary examinations corresponding to the patient's chief complaint and physical signs were arranged (directly determining negligence if textbook-level examination items were omitted). - **Interpretation obligation**: Identify abnormal results from performed examinations (e.g., ignoring "visible abnormalities" in imaging and laboratory reports, establishing interpretation negligence). - **Notification obligation**: Ensure that abnormal results are communicated and follow-up recommendations are implemented (e.g., failing to inform patients of abnormalities, disrupting the notification chain). - **Follow-up obligation**: Systemic issues such as failure to notify patients of follow-up appointments or share interdisciplinary information trigger hospital management system evaluations. Any breach in any of these four levels constitutes the basis for misdiagnosis liability claims. **Appraisal and determination of responsibility**: - Medical malpractice appraisal focuses on evaluating the causality of "delays" through indicators such as survival rate differences in contemporaneous diagnoses, treatment protocol downgrades, and timelines of metastasis/progression. Appraisers quantify the proportion of delays attributable to medical negligence versus disease natural progression. - Patients emphasize "early detection possibilities" (time trajectories of abnormal indicators and imaging follow-up intervals) and "delay consequences" (pathological staging comparisons across diagnoses). - Defendants argue for "clinical obscurity," "limited examination methods," or "patient non-compliance with follow-up." - Liability ratios are significantly reduced for delays caused by patients' own factors (e.g., non-attendance, refusal of examinations). **Multiple visit liability allocation**: - Cases involving initial misdiagnosis, repeat misdiagnosis, or diagnostic transfer across hospitals allocate liability based on respective negligence levels. Patients should not solely focus on the final diagnosing hospital—a complete liability map requires comprehensive timeline analysis. **Compensation calculation**: - Delay-induced damages are quantified as "treatment cost differences + quality-of-life losses + labor capacity impairments." - Death cases follow standard compensation for funeral expenses and dependents' living allowances, with mental compensation determined based on negligence and consequences. **Advice for patients**: - Retain all medical records, reports, and payment receipts from every visit (as evidence chains span years). - Proactively question and document abnormal results. **Advice for hospitals**: - Critical value management, abnormal report follow-ups, and cross-departmental information sharing constitute lifelines in misdiagnosis litigation. - Beijing's dense tertiary-level medical resources facilitate comprehensive appraisal and adjudication of lengthy evidence chains, making long-term recordkeeping patients' most valuable strategy.

IV. Practical suggestions and legal basis

The first step is to archive the timeline: arrange all medical records, reports, and medical orders chronologically; the second step is to conduct mandatory screening: identify critical points through four stages of examination, interpretation, notification, and follow-up; the third step is to determine liability: the proportion of the delay in treatment and the progression of the disease will be assessed by experts; the fourth step is to hold multiple hospitals accountable: each hospital will claim responsibility based on the degree of their negligence. Main legal basis: Article 121 and Article 122 of the Civil Code of the People's Republic of China; the provisions on fault and causation in the Judicial Interpretation of Medical Damage (amended in 2020); the Key Points of Medical Quality and Safety Core Systems (systems related to critical values and follow-up); the specific application shall be subject to the currently effective regulations.

5. Henglu Law Firm's Reminder

The evidence of the misdiagnosis case is the "timeline": the report form showing the first appearance of abnormal indicators might be the decisive factor in the entire case. Three habits—keeping medical records, inquiring about abnormalities, and documenting follow-up examinations—are far more cost-effective than seeking legal redress after the fact.

VI. Frequently Asked Questions

Q1: Are medical examination institutions liable for misdiagnosis in the same way as hospitals?

Similarly, if the physical examination institutions fail to fulfill their corresponding obligations of due care, they shall be dealt with in accordance with the liability for medical damage.

Q2: If there are abnormalities in the reporting system but no notification is given, does this count as a missed diagnosis?

This constitutes a violation of the obligation to inform and follow up, and the responsibility for managing critical values and abnormal results lies with the hospital.

Q3: How should we calculate the damage caused by the six-month delay?

The compensation shall be made within the liability ratio according to the phased differences confirmed by the appraisal and the extent of the treatment downgrading.

Q4: Does the patient not go for a follow-up examination, which might reduce their liability?

For patients who have been explicitly informed of the need for a review but have failed to attend the follow-up appointment, the proportion of medical liability will be correspondingly reduced.

Q5: What if multiple hospitals are at fault?

The co-defendants shall share the liability according to their respective faults and causes, and bear the responsibility respectively.
