Every drop matters

A ready supply of safe blood in sufficient quantities is a vital component of modern health care. In 2015-16, India was 1.1 million units short of its blood requirements. Here too, there were considerable regional disparities, with 81 districts in the country not having a blood bank at all. In 2016, a hospital in Chhattisgarh turned away a woman in dire need of blood as it was unavailable. She died on the way to the nearest blood bank which was several hours away. Yet, in April 2017, it was reported that blood banks in India had in the last five years discarded a total of 2.8 million units of expired, unused blood (more than 6 lakh litres). Vigil after collection To prevent transfusion-transmitted infections (TTIs), collected blood needs to be safe as well. Due to practical constraints, tests are only conducted post-collection. Thus blood donor selection relies on donors filling in health questionnaires truthfully. The collected blood is tested for certain TTIs such as HIV and if the blood tests positive, it has to be discarded. However, these tests are not foolproof as there is a window period after a person first becomes infected with a virus during which the infection may not be detectable. This makes it crucial to minimise the risk in the first instance of collection. Collecting healthy blood will also result in less blood being discarded later. Blood that is donated voluntarily and without remuneration is considered to be the safest. Unfortunately, professional donors (who accept remuneration) and replacement donation (which is not voluntary) are both common in India. In the case of professional donors there is a higher chance of there being TTIs in their blood, as these donors may not provide full disclosure. In the case of replacement donation, relatives of patients in need of blood are asked by hospitals to arrange for the same expeditiously. This blood is not used for the patient herself, but is intended as a replacement for the blood that is actually used. In this way, hospitals shift the burden of maintaining their blood bank stock to the patient and her family. Here again, there could be a higher chance of TTI’s because replacement donors, being under pressure, may be less truthful about diseases. The regulatory framework which governs the blood transfusion infrastructure in India is scattered across different laws, policies, guidelines and authorities. Blood is considered to be a ‘drug’ under the Drugs & Cosmetics Act, 1940. Therefore, just like any other manufacturer or storer of drugs, blood banks need to be licensed by the Drug Controller-General of India (DCGI). For this, they need to meet a series of requirements with respect to the collection, storage, processing and distribution of blood, as specified under the Drugs & Cosmetics Rules, 1945. Blood banks are inspected by drug inspectors who are expected to check not only the premises and equipment but also various quality and medical aspects such as processing and testing facilities. Their findings lead to the issuance, suspension or cancellation of a licence. In 1996, the Supreme Court directed the government to establish the National Blood Transfusion Council (NBTC) and State Blood Transfusion Councils (SBTCs). The NBTC functions as the apex policy-formulating and expert body for blood transfusion services and includes representation from blood banks. However, it lacks statutory backing (unlike the DCGI), and as such, the standards and requirements recommended by it are only in the form of guidelines.
