Why some stored blood is always discarded and why that should not deter blood donors

Blood donation coordinator Rajat Agarwal talks about how blood collection takes place and the inevitability of some blood being unused.

In the last five years, 28 lakh units of blood have been discarded by the blood banks across the country, the Times of India recently reported. Citing data from the National Aids Control Organisation, the report pointed out that, at the same time, there has been a shortfall of nearly 30 lakh units of blood in the country.

The National Aids Control Organisation, which regulates blood transfusion services, has 2,854 recognised blood banks. Most of these blood banks function in urban and periurban areas. Almost 73 of the 707 districts in the country do not have blood banks.

Rajat Agarwal, a programme coordinator for voluntary blood donation at the Sankalp India Foundation in Bengaluru, spoke to Scroll.in on why blood gets discarded. Sankalp India Foundation aids voluntary blood donation and connects blood banks across Karnataka. While discussing pitfalls in India’s system, Agarwal emphasised that a certain amount of blood has to be discarded for a healthy blood banking system to thrive in the country. Here are excerpts of the conversation.

Why is donated blood wasted or discarded even when there is a shortage of it?
When somebody donates blood, it is divided into three components – packed cells or red blood corpuscles, platelets and plasma. Packed cells last between 35 days and 42 days, plasma can last about a year and platelets last only 10 days.

The demand is most for red blood cells, less for platelets, and least for plasma. There would be certain amount of wastage of platelets and plasma. More platelets are bound to be wasted because of their shorter shelf life.

There are also cases where the donor does not complete the donation. Those bags have to be discarded. As per the Food and Drug Administration norms, one percent of platelets donated has to be sent for a sterility testing [a routine activity to test for bacterial contamination of blood]. A little more than one per cent of blood is [found to be] infected after being tested, so cannot be used.

So even the best of blood banks will discard blood. Nobody intentionally wastes blood. The blood bank, whether private or public, loses money on each unit wasted.

So you are saying wastage is inevitable.
Yes, some wastage is inevitable. However, the immediate impact of sharing wastage data without explaining the underlying reasons strongly undermines voluntary blood donation campaign. Already donors are questioning: “There is so much blood wasted. Why should we donate?”

A person’s blood being wasted is a strong emotional feeling. We had a blood donation camp in Bangalore yesterday and we heard this from several people.

We have seen a red blood cell shortage so intense that units are consumed in four to five days. The government is trying to make more blood storage centres. [which are not allowed to process blood but just store it] where there are no blood banks. That could implicitly mean wastage is going to increase. With highly unpredictable demand, one cannot be sure if every unit supplied to these centers would get used. If in some village, if there is a maternal death, everybody will be up in arms.

At times there might be gross-negligence where the blood is not stored properly. But it is one thing to have a few black sheep and another to say the system itself is faulty.

Why are big blood donation camps a problem?
We do not believe in large drives, and definitely not for just one blood bank. They are definitely a menace. No blood bank has the capacity to process and store very large amounts of blood. If somebody wants to create a record [of voluntary donors], they simply aggregate the already existing blood donors rather than motivating new ones, thereby affecting the continuous supply of blood.

What amount of wastage is acceptable across the world? How are other countries reducing wastage of blood?
Unfortunately that information is not available. I am not aware of a published reference. But most countries do not look at blood donation like we do. Any country which has a healthy blood supply will want to overprovision and have more units of blood than they require. The only difference would be that in countries such as the United States, they have large centralised blood banks, which can estimate the required amounts of blood required. They may cancel a few drives and reschedule them if necessary.

How is the government ensuring efficient distribution of blood?
In 2015, the National Blood Transfusion Council took a decision that blood banks can transfer the blood to hospitals or to other banks. This practice, if adopted universally, can facilitate proper use of components. But it has not yet been adopted universally. The government has also set up a better network of supply storage centre vehicles that transport blood from one to another.

The transfer of blood between blood banks has not reached a level where all blood banks, irrespective of whether the bank is from a private sector or public, transfer units and avoid any wastage. There are still drug control departments in the country who will get wild at the idea of inter-blood bank blood transfer.

Implementation is an ongoing issue. But, I would be happier if we encourage increased supply of blood even at the cost of losing few units. We are far from ensuring enough blood for all our patients. It otherwise puts pressure in the reverse direction.

How can the government work towards making the blood banking more efficient?
The government should set up a committee oversee and monitor the implementation of the orders. We need a system to periodically assess the extent to which blood is discarded and evaluate why the provisions laid by the system were not helpful in preventing it. Regular monitoring and focus upon implementation and adoption will make the system far better.

As far as possible, people should be motivated to donate blood. There are many people suffering from shortage of blood every single day. We need metropolitan blood banks which can collect and process large units of blood and then hand them over to smaller storage centres.

The government has given permission for banks to give away the plasma for fractionation [a process by which blood plasma is separated into its components] to companies that can make drugs of it. The government should set up a public sector fractionation centre. The drugs can then be used by people who suffer from blood related genetic disorders such as hemophilia.

India’s urban water crisis calls for an integrated approach

We need solutions that address different aspects of the water eco-system and involve the collective participation of citizens and other stake-holders.

According to a UN report, around 1.2 billion people, or almost one fifth of the world’s population, live in areas where water is physically scarce and another 1.6 billion people, or nearly one quarter of the world’s population, face economic water shortage. They lack basic access to water. The criticality of the water situation across the world has in fact given rise to speculations over water wars becoming a distinct possibility in the future. In India the problem is compounded, given the rising population and urbanization. The Asian Development Bank has forecast that by 2030, India will have a water deficit of 50%.

Water challenges in urban India

For urban India, the situation is critical. In 2015, about 377 million Indians lived in urban areas and by 2030, the urban population is expected to rise to 590 million. Already, according to the National Sample Survey, only 47% of urban households have individual water connections and about 40% to 50% of water is reportedly lost in distribution systems due to various reasons. Further, as per the 2011 census, only 32.7% of urban Indian households are connected to a piped sewerage system.

Any comprehensive solution to address the water problem in urban India needs to take into account the specific challenges around water management and distribution:

Pressure on water sources: Rising demand on water means rising pressure on water sources, especially in cities. In a city like Mumbai for example, 3,750 Million Litres per Day (MLD) of water, including water for commercial and industrial use, is available, whereas 4,500 MLD is needed. The primary sources of water for cities like Mumbai are lakes created by dams across rivers near the city. Distributing the available water means providing 386,971 connections to the city’s roughly 13 million residents. When distribution becomes challenging, the workaround is to tap ground water. According to a study by the Centre for Science and Environment, 48% of urban water supply in India comes from ground water. Ground water exploitation for commercial and domestic use in most cities is leading to reduction in ground water level.

Distribution and water loss issues: Distribution challenges, such as water loss due to theft, pilferage, leaky pipes and faulty meter readings, result in unequal and unregulated distribution of water. In New Delhi, for example, water distribution loss was reported to be about 40% as per a study. In Mumbai, where most residents get only 2-5 hours of water supply per day, the non-revenue water loss is about 27% of the overall water supply. This strains the municipal body’s budget and impacts the improvement of distribution infrastructure. Factors such as difficult terrain and legal issues over buildings also affect water supply to many parts. According to a study, only 5% of piped water reaches slum areas in 42 Indian cities, including New Delhi. A 2011 study also found that 95% of households in slum areas in Mumbai’s Kaula Bunder district, in some seasons, use less than the WHO-recommended minimum of 50 litres per capita per day.

Water pollution and contamination: In India, almost 400,000 children die every year of diarrhea, primarily due to contaminated water. According to a 2017 report, 630 million people in the South East Asian countries, including India, use faeces-contaminated drinking water source, becoming susceptible to a range of diseases. Industrial waste is also a major cause for water contamination, particularly antibiotic ingredients released into rivers and soils by pharma companies. A Guardian report talks about pollution from drug companies, particularly those in India and China, resulting in the creation of drug-resistant superbugs. The report cites a study which indicates that by 2050, the total death toll worldwide due to infection by drug resistant bacteria could reach 10 million people.

A holistic approach to tackling water challenges

Addressing these challenges and improving access to clean water for all needs a combination of short-term and medium-term solutions. It also means involving the community and various stakeholders in implementing the solutions. This is the crux of the recommendations put forth by BASF.

The proposed solutions, based on a study of water issues in cities such as Mumbai, take into account different aspects of water management and distribution. Backed by a close understanding of the cost implications, they can make a difference in tackling urban water challenges. These solutions include:

Recycling and harvesting: Raw sewage water which is dumped into oceans damages the coastal eco-system. Instead, this could be used as a cheaper alternative to fresh water for industrial purposes. According to a 2011 World Bank report, 13% of total freshwater withdrawal in India is for industrial use. What’s more, the industrial demand for water is expected to grow at a rate of 4.2% per year till 2025. Much of this demand can be met by recycling and treating sewage water. In Mumbai for example, 3000 MLD of sewage water is released, almost 80% of fresh water availability. This can be purified and utilised for industrial needs. An example of recycled sewage water being used for industrial purpose is the 30 MLD waste water treatment facility at Gandhinagar and Anjar in Gujarat set up by Welspun India Ltd.

Another example is the proposal by Navi Mumbai Municipal Corporation (NMMC) to recycle and reclaim sewage water treated at its existing facilities to meet the secondary purposes of both industries and residential complexes. In fact, residential complexes can similarly recycle and re-use their waste water for secondary purposes such as gardening.

Also, alternative rain water harvesting methods such as harvesting rain water from concrete surfaces using porous concrete can be used to supplement roof-top rain water harvesting, to help replenish ground water.

Community initiatives to supplement regular water supply: Initiatives such as community water storage and decentralised treatment facilities, including elevated water towers or reservoirs and water ATMs, based on a realistic understanding of the costs involved, can help support the city’s water distribution. Water towers or elevated reservoirs with onsite filters can also help optimise the space available for water distribution in congested cities. Water ATMs, which are automated water dispensing units that can be accessed with a smart card or an app, can ensure metered supply of safe water.

Testing and purification: With water contamination being a big challenge, the adoption of affordable and reliable multi-household water filter systems which are electricity free and easy to use can help, to some extent, access to safe drinking water at a domestic level. Also, the use of household water testing kits and the installation of water quality sensors on pipes, that send out alerts on water contamination, can create awareness of water contamination and drive suitable preventive steps.

Public awareness and use of technology: Public awareness campaigns, tax incentives for water conservation and the use of technology interfaces can also go a long way in addressing the water problem. For example, measures such as water credits can be introduced with tax benefits as incentives for efficient use and recycling of water. Similarly, government water apps, like that of the Municipal Corporation of Greater Mumbai, can be used to spread tips on water saving, report leakage or send updates on water quality.

Collaborative approach: Finally, a collaborative approach like the adoption of a public-private partnership model for water projects can help. There are already examples of best practices here. For example, in Netherlands, water companies are incorporated as private companies, with the local and national governments being majority shareholders. Involving citizens through social business models for decentralised water supply, treatment or storage installations like water ATMs, as also the appointment of water guardians who can report on various aspects of water supply and usage can help in efficient water management. Grass-root level organizations could be partnered with for programmes to spread awareness on water safety and conservation.

For BASF, the proposed solutions are an extension of their close engagement with developing water management and water treatment solutions. The products developed specially for waste and drinking water treatment, such as Zetag® ULTRA and Magnafloc® LT, focus on ensuring sustainability, efficiency and cost effectiveness in the water and sludge treatment process.

BASF is also associated with operations of Reliance Industries’ desalination plant at Jamnagar in Gujarat.The thermal plant is designed to deliver up to 170,000 cubic meters of processed water per day. The use of inge® ultrafiltration technologies allows a continuous delivery of pre-filtered water at a consistent high-quality level, while the dosage of the Sokalan® PM 15 I protects the desalination plant from scaling. This combination of BASF’s expertise minimises the energy footprint of the plant and secures water supply independent of the seasonal fluctuations.
