[Direct answer]In the Beijing area, the responsibilities of blood supply institutions and medical institutions can be investigated simultaneously, and compensation can be claimed through paths such as medical damage and product liability. According to Article 1223 of the Civil Code of the People's Republic of China (effective January 1, 2021), if a patient is harmed due to defects in drugs, disinfection products, or medical devices, or due to the input of unqualified blood, the patient may request compensation from the drug marketing authorization holder, the manufacturer, or the blood supply institution, or from the medical institution; if the patient requests compensation from the medical institution, the medical institution, after making compensation, has the right to seek recourse from the responsible drug marketing authorization holder, manufacturer, or blood supply institution. Therefore, patients can either claim compensation from the blood supply institutions or directly from the medical institutions that performed the transfusion, and then seek recourse from each other among the relevant parties. The key to accountability lies in two points: first, proving the causal relationship between the transfusion and the infection, which usually requires professional appraisals such as virus gene sequence comparison; second, confirming whether the blood is unqualified or whether there are faults in the medical institutions. In practice, it is recommended to seal the medical records and transfusion-related records as soon as possible, apply for appraisal in time, and pay attention to the statute of limitations for litigation.

I. Problem Background and Typical Scenarios

Blood transfusion-related infectious diseases are a typical cross-cutting issue involving medical and product liability. Patients often only discover the infection years later, making it difficult to seek legal redress. There are four typical scenarios: First, after a surgery or treatment, patients are diagnosed with infectious diseases such as hepatitis C, hepatitis B, and HIV several months or even years later. Second, the blood donor may be in the window period, during which routine tests fail to detect the virus. Third, if the patient also has other infection routes, it is difficult to rule out the causal relationship. Fourth, due to the long time span, it is difficult to retrieve medical records and blood samples. Although there are many medical institutions and a large blood usage volume in the Beijing area, and blood management is relatively standardized, the window period and limitations of testing technology may still lead to similar disputes. Patients should fix evidence and identify the responsible parties as soon as possible.

II. Key points of contention

First, how to prove the causal relationship between blood transfusion and infection, and the role of gene sequence comparison. Second, the division of responsibilities and compensation between blood supply institutions and medical institutions. Third, whether the detection limitations of the blood donation window period can be used as a defense against liability. Fourth, the exclusion of other possible infections in patients. Fifth, the scope of compensation and claims for subsequent treatment costs. Sixth, the commencement and maximum duration of the statute of limitations for litigation.

III. Professional analysis by Henglue Lawyers

When handling such disputes, Henglue Lawyers usually organize their work around two main lines: "causality" and "subject responsibility". Regarding causality, they can determine whether the virus in the patient's body is homologous to the virus gene sequence of the blood donor or stored blood samples by comparing them, thus proving that the infection originated from blood transfusion. If blood samples cannot be obtained, they can also prove it indirectly by excluding other infection routes and reviewing the detection results before and after transfusion. Regarding subject responsibility, the Civil Code explicitly grants patients the right to choose, allowing them to sue either the blood supply institutions or medical institutions. The responsibility between the two parties is ultimately shared according to fault and causality, which is very beneficial to patients and can avoid them being trapped in a stalemate due to unclear responsibility subjects. It should be noted that when blood supply institutions use the defense of "undetectable during the window period", the court will usually review whether their blood collection, detection, and management systems are compliant and whether there are other faults. On the part of the patients, they should seal the medical records and blood transfusion records as early as possible and keep the pre- and post-transfusion test reports. Since such cases involve both medical and legal expertise, appraisal and evidence organization are often the key to success or failure. Enlisting the help of professional lawyers as early as possible can help avoid the loss of crucial evidence.

IV. Practical suggestions and legal basis

Action recommendations: First, immediately seal and copy the medical records, blood transfusion records, and test reports after discovering an infection; Second, preserve blood samples or request to retrieve stored blood samples as much as possible to create conditions for genetic comparison; Third, organize information on the time of blood transfusion, medical institutions, and blood sources to clarify the responsible parties; Fourth, apply for medical damage or relevant professional appraisals to prove the causality and fault; Fifth, preserve evidence of all treatment costs and follow-up treatment needs; Sixth, pay attention to the statute of limitations and assert rights in a timely manner.

5. Henglu Law Firm's Advice

Firstly, patients can file claims against blood supply institutions or medical institutions, and the choice lies with the patients themselves. Secondly, establishing a causal relationship is the most difficult part, and genetic sequence comparison is the most effective method. Thirdly, the sealed medical records and blood transfusion records must be preserved as soon as possible. Fourthly, the defense of the "window period" may not necessarily exempt from liability, and it still depends on whether the management is in compliance with regulations. Fifthly, attention should be paid to the statute of limitations, and claims should be asserted as soon as possible after discovery.

VI. Frequently Asked Questions

Q1: Can I sue the hospital for a blood transfusion-related infection?

Yes. According to Article 1223 of the Civil Code of the People's Republic of China (effective January 1, 2021), if a patient is harmed due to the infusion of unqualified blood, the patient may request compensation from the blood supply institution or the medical institution. After the medical institution makes compensation, it has the right to recover the compensation from the responsible party. Therefore, it is permissible to directly sue the hospital that performed the blood transfusion.

Q2: How can we prove that the infection was caused by a blood transfusion?

The best approach is to compare the genetic sequences of the virus. By comparing whether the virus in the patient's body is homologous to the virus genetic sequences of the blood donor or stored blood samples, the source of the infection can be directly proven. If it's not possible to obtain blood samples, the source of the infection can be indirectly proven by reviewing the test results before and after transfusion, excluding other infection routes, and obtaining expert appraisals. The earlier the evidence is fixed, the more beneficial it will be.

Q3: If the window period is not detected, is the hospital exempt from liability?

Generally, exemption from liability is not automatic. Although the window period is a limitation of existing detection technology, the court will still review whether the blood collection institutions' blood collection process, detection methods, and donor screening and management systems comply with regulations, and whether there are any faults in the transfusion process of medical institutions. If the relevant parties have fulfilled their reasonable duty of care, they may be able to mitigate their liability; if there are management omissions, they will still need to bear corresponding compensation responsibilities.

Q4: If I only find out about it many years later, can I still file a claim for compensation?

It depends on the starting date of the statute of limitations. The statute of limitations for litigation is usually calculated from the date when the right holder knows or should have known that their rights have been infringed and the obligee's identity. Therefore, if the diagnosis is confirmed many years later, the statute of limitations is generally calculated from the date when the diagnosis is confirmed and the right holder learns about the connection with the blood transfusion. At the same time, it is subject to the limitation of the maximum protection period. It is recommended to sort out the time of blood transfusion and the time of diagnosis as soon as possible, consult a lawyer to evaluate the statute of limitations, and fix the evidence.

Q5: How can I claim the subsequent treatment costs?

It can be claimed either together with or separately from other claims. If the subsequent treatment costs have been determined or can be estimated, they can be claimed together in the lawsuit; if they have not yet occurred or the amount is uncertain, the claimant can first claim for the expenses that have already occurred, and then claim for the subsequent treatment costs after they actually occur, or apply for an appraisal to determine the subsequent treatment costs. When claiming together, the claimant should provide the diagnosis certificate and treatment plan recommendation from the medical institution.
