               Introduction
               The corporate-wide average platelet wastage is around 2-3%. For a long time, there is an exceedingly high platelet wastage
               of >30% (> 600 units per year) in North District Hospital (NDH), which also has a restricted platelet stock.
               Review of transfusion data identifies that there is a vicious cycle that platelets are over-reserved and for relatively non-
               indicated  patients  (e.g.  platelet  count  >100x109/L)  for  fear  of  lacking  platelet  supply when  needed.  With  a  short  self-life
               of platelets (five days), reservation for just-in-case transfusion further reduces the availability of platelets stock and also
               contributes to high platelet wastage, deferring negotiation for increase in platelet stock from HKRCBTS as monitored by
               Central Committee (Transfusion service).
               Objectives
               (1) To reduce platelet wastage in NDH; (2) to maintain a stable platelet stock in terms of quantity and functional life with timely
               supply; (3) to break the above vicious cycle by addressing the worries of clinical teams and hence promote a better working
               partnership from bench to bedside

               Methodology
               A cluster-based inventory management system and logistics are developed and implemented through dynamic monitoring of
               platelets stock with temperature monitored re-direction and circulation of platelet units within New Territories East Cluster.

               Phase one:
               Since March 2015, we have successfully negotiated with Prince of Wales Hospital (PWH) for taking up nearly expired (Day
               four/five) platelets when they are not used up by routine cluster transport on weekdays, and by taxi on weekends and public
               holiday. To facilitate urgent platelet transfusion when platelet stock is not available in NDH, PWH has also backed up the
               platelet stock support by a direct one-way delivery (PWH to NDH) instead of two-way delivery (NDH to PWH to NDH).
               Phase two:
               Further to these stock logistic initiatives and drastic improvement in platelet wastage, we have successfully liaised with
               HKRCBTS again to double the regular platelet stock in NDH to a higher level of eight units since November 2015.

               Results
               By  a  cluster-based  service,  PWH  Blood Bank has  served as  a  secondary  parent  stock and  also absorbed  the  wastage
               generated by NDH through dynamic stock monitoring and higher utilisation rate. No raise in platelet wastage is observed in
               PWH (2%).
               Phase one programme has dramatically reduced the platelet wastage in NDH from >30% (>600 units per year) to 7% (116
               units) in 2015.                                                                                     Wednesday, 17 May

               Phase two programme ensures a very stable stock in NDH with reduction of monthly extra platelet transportation from PWH
               or HKRCBTS from 15 to 7 times on average. This timely supply also addresses the worries of clinical teams with alleviation of
               tension amongst clinical and laboratory frontlines. Less just-in-case reservation is recorded. A further reduction of platelets
               wastage to 4% (58 units) is observed from January to November 2016.

               This pilot programme illustrates that a win-win outcome is possible on both resources utilisation and service provision
               through a cluster-based inventory management system.
