Implementation of Indian National plasma policy at blood bank of a tertiary care hospital: A step towards strengthening of blood transfusion services.

INTRODUCTION: The World Health Organization has advocated that every country should make its own policy for ensuring safe and adequate supply of plasma derived medicinal products through mobilization and usage of locally collected plasma. The National Plasma Policy (NPP) of India was published in 2014 with a dual objective to achieve self sufficiency in the production of plasma derived medicinal products and at the same time to augment the component preparation facilities in India and overall upliftment of blood transfusion services in the country. Thus the present study was done to access the impact of implementation of NPP in our blood bank on the blood transfusion services in our hospital. MATERIALS AND METHODS: The present study was a retrospective observational study conducted in the department of transfusion medicine of a tertiary care hospital in India involving analysis of data from 1st January 2019 till 31st December 2022. For the purpose of data analysis the time period was divided into 2 periods: (i) Pre-NPP implementation period from 1st January 2019 till 31st December 2020; (ii) Post-NPP period from 1st January 2021 till 31st December 2022. The following parameters were compared for the two periods: (i) component preparation rate; (ii) percentage of component therapy; (iii) total number of FFP transferred to plasma fractionation centers; (iv) total amount of exchange amount generated in lieu of transferred FFP to plasma fractionation centers. RESULTS: The component preparation rate after NPP implementation was significantly higher as compared to the pre NPP implementation period (93.81% vs 56.70%; p = 0.007). The percentage of component therapy in the patients was also significantly higher as compared to the pre-NPP implementation period (97.9% vs 73.6%; p = 0.005). The total amount of exchange amount generation in Indian rupee (INR) after NPP implementation was INR 1419462 (15835€) while it was INR 636898 (7105€) in the pre NPP implementation period. This amount was utilized for procurement of various blood bank equipment, in addition 2 lab technicians were also hired for the blood bank. CONCLUSIONS: The implementation of NPP resulted in upliftment of blood transfusion services in our hospital. Other low and middle income countries can benefit from implementation of similar plasma policy in their countries.

Plateletpheresis donor deferral patterns at a tertiary care hospital in North India: A need for rethink of haemoglobin cutoff.

INTRODUCTION: The donor deferral criteria for blood or apheresis donations are established for two main reasons: (i) to ensure the safety of the blood donor (non-maleficence); (ii) to obtain safe blood of standard quality that has therapeutic benefit for the patient (beneficence). This study was planned to assess the various causes and patterns of plateletpheresis donor deferral in our hospital and to subsequently assess whether any evidence based changes can be done in the current plateletpheresis donor deferral criteria in India to maximize the platelet donor pool without compromising donor safety. MATERIAL AND METHODS: The present study was conducted from May 2021 till June 2022 in the department of transfusion medicine of a tertiary care hospital in North India. The first part of the study was conducted from May 2021 till March 2022 to assess the various causes of donor deferral by analysing the plateletpheresis donor deferral data during the corresponding period. The second part of the study was conducted from April 2022 till June 2022, to assess: (i) average decrease in haemoglobin after plateletpheresis procedure; (ii) red blood cell loss during plateletpheresis procedure; (iii) to determine whether any correlation exists between donor haemoglobin and platelet yield. RESULTS: During the study period, a total of 260 donors were screened for plateletpheresis, out of which 221 (85%) donors were accepted and 39 (15%) donors were deferred for various reasons. Out of the 39 deferred donors, 33 (84.6%) were temporary deferrals, while 6 (15.4%) were permanent deferrals. Low haemoglobin (Hb < 12.5 g/dl) was a cause of deferral in 12.8% (n = 5) of the deferred donors. 192 (73.9%) out of the 260 donors were replacement donors. The calculated mean decrease in haemoglobin as a result of plateletpheresis procedure was 0.4 g/dl. No correlation was seen between donor pre-donation haemoglobin and platelet yield (p = 0.86, r = 0.06, R2 = 0.003). The calculated mean red cell loss as a result of plateletpheresis procedure was 28 ml. CONCLUSION: Low haemoglobin (<12.5 g/dl) is a significant cause of temporary plateletpheresis donor deferral in India. In view of the advancement in plateletpheresis technology, which has resulted in minimal red cell loss with the current generation apheresis devices, haemoglobin cutoff of 12.5 g/dl needs to be reconsidered. Perhaps, after performing a multi-centric trial, a consenscus can be reached for revision of haemoglobin cutoff for plateletpheresis donations.
