Human Milk Bank Processes: iThemba Lethu Breastmilk Bank, Durban, South Africa Anna Coutsoudis Professor, Dept Paediatrics & Child Health. University KwaZulu-Natal Durban, South Africa [email protected] Background info Brief description How did your human milk bank (HMB) began? When? Began in response to a need for sick AIDS orphans to be provided with optimum nutrition with immune benefits. Began in 2000 Who provided initial funding? How are ongoing operations funded? Integrated into government services? Initial seed funding provided by UNICEF – all future funding from donors – all local SA donors. Not integrated into government services. Who regulates /oversees HMB in your country/region (if any)? Oversight (very limited) provided by Human Milk Banking Association of South Africa. No government oversight yet, although is being planned. How many HMBs are part of your system? Where are they? 1 – plus a few satellite points at pharmacies where people can leave their milk for later collection. Also collect milk from private hospital NICUs Is there a central HMB that processes milk and distributes or many HMBs that process milk and distribute? (Centralized vs decentralized) Decentralised How many NICU/Neonatal wards/community homes does each bank serve? Are they collocated? Serves 2 homes of 6 children each – the actual number of children at any one time who receive milk varies – if we have insufficient milk, HIV infected children are prioritised and then the youngest infants. Milk from pre-term infants is donated to one of the local hospital NICus How many babies does your facility/system serve annually? Variable – approx 20 How many liters/year does your facility/system process annually? Approximately 150 litres from local mothers and we also receive donations from US mothers also approx 150 litres How many donor mothers initiate donation to your facility/system annually? 40 – 50 donors Page 2 Process Brief description of processes Staffing • 1 breastmilk bank manager – volunteers occasionally assist with pasteurising Donor recruitment • • Through antenatal clinics, women groups, word of mouth. Newspaper and magazine publicity – have produced video clips but too expensive to flight on TV Donor screening • Screening form for lifestyle risks – similar to blood donor screening and HIV and syphylis tests from pregnancy. Recipient eligibility and selection • No infections, healthy mother with hygienic home, fridge and freezer Handling and storage of donor milk (from donation to feeding) • Mothers given sterile bottles and information and training on expressing and storing of milk in a safe way. Each donor mother is given a donor number – she writes this number together with the date of expression on each bottle before freezing. When her freezer space is filled with donor milk she contacts the milk bank to collect the milk – then collected and stored frozen at the milk bank until pasteurisation. Pasteurisation done in large batches of about 72 bottles – defrosted and then pasteurised and re-frozen until it is dispensed to the homes for use by the children. Screening questionnaire • Have you received a blood transfusion or blood products in the last 12 months? • Do you regularly have more than 50ml of hard liquor or its equivalent in a 24-hour period? • Regular use of medications, or use of radio-active drugs or cytotoxins? • Are you a total vegetarian? • If yes, do you supplement your diet with B12 vitamins? • Do you use habit-forming drugs? • Do you smoke? • Have you ever had hepatitis B, HIV, or TB? • Have you ever had a sexual partner who is at risk for HIV, takes habitforming drugs, or is a haemophiliac? • Do you have a copy of the results of your anti-natal HIV and syphilis tests? • If not, would you be prepared to undergo a rapid test for HIV at your expense and submit the results to the screening officer? Process Brief description of process Transport of milk • Manager collects milk from mothers’ homes or collection depots in cooler box with ice packs and transports it to milk bank Pasteurization • Holder Pasteurisation – using automated Sterifeed Pasteuriser Tracking and record keeping • Each pasteurisation has batch number, temperature logging on computer Assessing milk quality and safety (ie. microbiology assays) • Micro assays on post-past’n sample – one random sample per batch and each new donor has first sample assayed. Quality assurance • Screening of mothers, HIV and syphilis test results, issue of sterile collection bottles; temperature control of freezers; temperature monitoring of pasteurising and cooling; batch numbers and donor number on each bottle; expiry date on each bottle Equipment/Location Brief description of process What is used/how many? • 1 x Sterifeed Pasteuriser • 1 x Freezer for unpasteurised milk and 1 for pasteurised • 1 x Refrigerators Additional HMB equipment • Lockable room with alarm • Computer requirements? • Generator for freezers • Dishwasher to wash bottles Referral/feeder/depot facilities? • 6 depots • Each depot has freezer – bottles supplied to them as well as screening forms? Neonatal ward equipment requirements? • n/a Other? • n/a Organizational Successes Brief description of top 3-5 successes Policy • Success with milk bank led to banks been set up in Gauteng and Western Cape Provinces – these hubs then grew independently • Advocacy work together with PATH led to National/regional policy and support for breastfeeding as well as roll out of donor milk banks. Operational • Donors have felt they can make a difference in the life of orphans – visiting infants that they donate milk for exposes them to the scourge of HIV. • Improvement in health of infants fed donor milk – when donor milk runs out problems with infants not being able to tolerate formula milk – switch over is often traumatic for care givers. Technology • Gradually progressed from equipment specifically developed for our milk bank by a South African company, to an international pasteuriser – Sterifeed. Page 7 Case Studies-Baby S • BW: 2.5 kg • Arrived :2 mths old • Weight: 3kg malnutrition, scabies, TB, respiratory distress and HIV pos. • Mother and grandmother full blown AIDS, mother died when he was 3 mths old • Put on breastmilk. Gained weight despite respiratory infections and diarrhoea. • Skin improved almost immediately He continued to receive the breast milk until he was 14 months old. He is a real delight and has a very infectious laugh. At 21 months, he started on HAART treatment and continued to do well. When he was 2 yrs old, he was adopted by a loving family who are thrilled to have him in their care, he has settled well with his family and he is flourishing in their care. Baby A was born prematurely weighing 1500g and was abandoned in hospital. He was brought to the home at 7 months of age weighing 2700g. In 7 months of being fed on formula he put on 1200g! In 2 weeks of being fed on donated breastmilk he put on 550g Donor Mom • Despite the fact that this mom is a busy GP, she donated milk for a period of 6 months, a total of 17.7 litres. • She stopped donating when her baby was 10 months old, not because she is no longer breast feeding, but rather because she has adopted an abandoned baby herself whom she is now breast feeding as well as continuing to feed her baby. • The baby’s mother had died shortly after birth from AIDS. Organizational Challenges Brief description of top 3-5 challenges Policy • Uncertainty around importance of donor milk, health care workers more comfortable working with formula milk, more experience. • Lack of policy level support for breastfeeding promotion. • Lack of guidance from Ministry of Health Operational • Funding for dedicated staff – staff normally wearing 2 or 3 hats • Insufficient donor milk due to insufficient donors – poor breastfeeding promotion – leads to many women discontinuing breastfeeding at 4 months • High percentage of HIV in our province – 43% prevalence in antenatal clinics – cuts eligible pool into half Technology • Time consuming – defrosting such a large number of bottles takes a long time but automated pasteuriser compensates for this.
