4 Foreword This has been another busy year for the BSMS, made all the more difficult by the ongoing changes in staffing the scheme. We have said goodbye (temporarily) to Sue Cotton who has been seconded to the NHSBT Integrated Transfusion Services stock project, and welcomed Elaine MacRate, who is managing the scheme until her return. A major part of our work in 2011/12 was to survey users to see how they would like the scheme to progress. We now have agreement for the key developments; the enhancements to VANESA to collect frozen component data and the facility for participants to collect reports electronically. The automatic transfer of data has long been a goal and we continue to explore the feasibility of implementing this. We received very positive feedback from scheme users and are gratified to know that it continues to be of value. The scheme has been collecting data on stock holding and wastage across the UK for some years now and remains the only source of this data. The data is somewhat fragmented however, but we continue to work towards being able to present data across the entire supply chain, demonstrating comparative data between the different blood services across the UK and Ireland, and delivering benefits for both hospitals and the blood services. The recently launched Patient Blood Management initiative aims to drive forward transfusion safety and appropriate use agendas and has emphasised the need for data to achieve this. These initiatives are really about changing practice, utilising benchmarking and review processes. The BSMS remains ideally placed to facilitate this. The BSMS has been involved in the AIM II pilot scheme, collecting data from Patient Administration Systems on the clinical use of blood. Participation in the scheme remains high and I am pleased to say that we are beginning to see data from Scotland and the Republic of Ireland. A key aim this year has been to broaden the staff groups who access data directly, and to encourage wider utilisation. In England, the Regional Transfusion Committees have embraced the data and we have had a good response from transfusion practitioners. I would still encourage the wider Transfusion Teams, including the Hospital Transfusion Committee chairs and consultant haematologists to access and utilise the data. We have produced new high level reports that we hope will help to expand this use of the data. As always, the scheme would not be the success that it is without the hard work and participation of the members and I would like to thank you all for your continued support. I am sure that you will join me in thanking Sue Cotton and her team for their continued hard work in making the scheme a continued success. Craig Taylor Steering Group Chair, Blood Stocks Management Scheme December 2012

5 3. About the Blood Stocks Management Scheme The Blood Stocks Management Scheme was established in April 2001 as a partnership between hospitals and blood services to maximise the use of donated blood and platelets, by increasing understanding of the entire blood supply chain. Data from blood services and hospitals are entered into a database either automatically or by manual entry via the BSMS website. The data stored include issues, inventory, wastage and shelf life of issued red cells and platelets. A range of reports can be generated automatically by participants from real time data, allowing the use of information on a day to day basis. In addition, a number of reports are generated by the scheme analysts and distributed periodically as hard copies to participants. Blood services and hospitals from the UK and the Republic of Ireland participate in the BSMS to contribute to the depth of information related to blood supply management. The BSMS continues to strive for improvements in stock management through a number of initiatives including inventory practice surveys and reports, publications, meetings and training events.

6 4. Participation in BSMS The BSMS relies on regular and accurate data input from both hospitals and blood services. The scheme has a list of registered participants, most contribute data regularly, some contribute their data less consistently. BSMS monitors the activity of hospital participants periodically so that bi monthly reminders can inform participants of missing data. Missing data can be entered retrospectively. A recent audit of the activity of NHSBT participants showed that over 80% of registered users enter their stock data on a daily basis, which was extremely reassuring. Activity by participant is defined as: Number of entries per month Red Cell Stock Red Cell Wastage Platelet wastage Regular Activity >=16 >=1 >=1 Partial Activity <16 OR 0 OR 0 None Hospital activity by blood service is shown in Tables 1a to 1e and compares activity in March 2011 with March Table 1a Hospital Activity within England and North Wales (NHSBT) Blood Service Activity Status Hospital count 2011 % 2011 Hospital count 2012 % 2012 NHSBT Regular % % NHSBT Partial 45 17% 34 13% NHSBT None 6 2% 14 5% Table 1b Hospital Activity within Northern Ireland (NIBTS) Blood Service Activity Status Hospital count 2011 % 2011 Hospital count 2012 % 2012 NIBTS Regular 6 60% 9 90% NIBTS Partial 4 40% 1 10%

8 5. Highlights from 2011/12 We organised and delivered 6 regional meetings for hospital and blood service staff. 235 delegates attended from hospitals and blood services in England, Wales, Scotland, Northern Ireland and the Republic of Ireland. The aim of the meetings was to share good practice and provide tools and ideas to improve blood inventory management. Various topics were explored including blood drivers, stock sharing relationships and the challenges and limitations of stocking platelets in hospitals. We undertook a consultation with hospitals to extend the transparency of the Blood Stocks Management Scheme (BSMS) hospital data to include NHS Blood and Transplant and in Wales to include the Welsh Blood Service. Increased visibility of data between hospitals and blood services is already in place in Scotland, Northern Ireland and the Irish Republic. The benefits of increasing data transparency are to enable improvements to the blood supply chain which will benefit both hospitals and Blood Services. There was overwhelming hospital support for the proposal and the BSMS Steering group agreed that the hospital data should be made available to NHSBT and WBS. We undertook a strategy survey with hospital participants with the objectives of assessing Whether the BSMS continues to provide benefits to hospitals in terms of management of blood stocks. What services should be provided by the BSMS in the future that would be of benefit to hospitals and Blood Services. The survey provided evidence of the benefits to the management of blood stocks and informed the BSMS Steering Group in terms of the future strategy of the BSMS. We presented three posters at the BBTS meeting held in Glasgow during September How much blood is in the supply chain? A new method for calculating platelet usage categories in the BSMS Reduction in wastage in the blood supply chain by sharing stock We had three papers published in peer reviewed journals Wilding, R., Cotton, S., Chapman, J., Yates, N.

SNBTS: No data available (1) IBTS: O RhD Neg issues were 14.0%, compared to 15.8% in 2010/11. (1) The Scottish National Blood Service was unable to provide an automatic download of data until late Data has now been supplied retrospectively, but we were unable to analyse it for this report.

11 7. Key Findings 2011/ Red Cell Supply Chain Red cell issues to hospitals during 2011/12 were relatively stable across NHSBT, NIBTS and IBTS. Changes in issues were between + / 0.5%. The red cell issues in WBS appear to have risen slightly more by comparison, with an increase of 2.1%. Issuable Stock Index (ISI) is one of the datasets calculated by BSMS and is based on the number of days stock held. This varies across the blood services from around 6 days stock held in Eire, to an average of more than 10 days stock in Northern Ireland. The level of stock held by blood services also changes throughout the year. Collections (and therefore stock levels) are affected by bank holidays, holiday periods in general and other factors such as adverse weather and sickness. It should be noted that detailed demand planning is undertaken for any predictable disruptions, such as the four day holiday weekends which occurred last year during a two week period, covering Easter and the Royal Wedding. Hospitals were approached for information about their predicted activity over that period but many hospitals were unable to offer any insight about predicted activity and subsequently the blood services ensured sufficient stock was available to meet normal demand. Most hospitals, however, experienced a reduced demand for those days. As issues were reduced, stock levels therefore become higher than normal. For England and North Wales, a prolonged period between March to May 2011 of higher stock levels (and higher ISI) was seen and this resulted in NHSBT hospitals demonstrating a higher than average wastage for April and May The amount of red cell stock normally held by each of the blood services varies. The variation in stock held between the blood services is large with IBTS ranging from 5.7 to 6.8 ISI and Wales ranging from 6.0 to 15.9 this year (Table 2). Table 2 Issuable Stock Index highest and lowest months in 2011/12 NHSBT NIBTS WBS SNBTS IBTS Lowest ISI 8.4 (Mar 12) 7.8 (Jan 12) 6.0 (Oct 11) Ave ISI 5.7 (Mar 12) Highest ISI 10.7 (Sep 11) 15.2 (Mar 12) 15.9 (Mar 12) (Jan 12)

12 The Irish Blood Transfusion service has the lowest Issuable Stock Index and the hospitals that report time expiry wastage from Ireland have lower TIMEX than hospitals supplied by the other services. As only 50% of hospitals served by IBTS report wastage, the overall wastage as a % of issues for all IBTS hospitals cannot be calculated. Table 3 Hospital Wastage: Time Expiry TIMEX (by Blood Service provider) Time expiry as percentage of issues NHSBT NIBTS WBS SNBTS IBTS 1.4% 3.4% 2.1% 1.0% The number of units being wasted with a fate of Out of temperature control outside the laboratory (OTCOL) has reduced slightly for hospitals served by NHSBT, NIBTS and IBTS. Table 4 All hospital wastage as a % of issues highest and lowest months in 2011/12 NHSBT NIBTS WBS SNBTS IBTS Lowest 1.8 (Feb 12) 3.7 (Dec 11) 2.0 (Apr 11) N/A N/A Highest 2.5 (Aug 11) 6.0 (May 11) 3.2 (Feb 12) N/A N/A 7.2 O RhD Negative Issues BSMS has continued to analyse usage and wastage of Group O RhD Negative red cells, as collection of sufficient numbers of this group, is one of the biggest challenges for the UK blood services. Issues have increased again, albeit slightly, for NHSBT, NIBTS and WBS. The IBTS has had the highest percentage of O RhD Negative issues previously, and has this year reduced their O RhD Negative issues by 1.8 percentage points, to 14.0% of total issues. We also report on hospital wastage of O RhD Negative units, although this has proved controversial. Some hospital laboratories transfuse these units to all group recipients to avoid wastage (mismatch), whilst others retain the units until they expire, for use for O RhD Negative patients only. Table 5 shows the differences between hospitals, by each blood service.

13 Table 5 Percentage of O Negative red cells wasted in hospitals Hospitals served by 2009/ / /12 NHSBT 4.4% 4.3% 3.7% Northern Ireland 5.8% 5.6% 7.0% Wales 2.8% 2.5% 3.9% Irish BTS 14.0% 7.3 Platelet Supply Chain Platelet issues have increased in all countries where this data is provided. NHSBT has seen an increase of 9.2%, Northern Ireland an increase of 9.4%, whilst IBTS increased by 6.3% and SNBTS by 3.9%. Although the figures are not available, Wales has also reported an increase in platelets issued. As discussed previously, there is evidence that some platelets may be used inappropriately ( hospital.blood.co.uk/safe_use/clinical_audit/national_comparative/ NationalComparativeAuditReports/index.asp) but other potential reasons for this increase, such as supply of platelets for massive haemorrhage trauma packs, have been suggested. There has not been an associated rise in wastage. NHSBT had a higher platelet ISI this year than The lowest ISI was 2.1 for two months, with most months over 2.2. For Northern Ireland, ISI was generally lower than 1.5 and this was lower than IBTS fluctuates between 2.1 and 2.9 ISI, similar to last year. Hospital wastage varies across the blood services, but ordering platelets for specific cases and subsequently not using them, remains the largest reason for wastage. Combined wastage for MONU (medically ordered not used) and SONU (surgically ordered not used) was 67% for NHSBT, 54% for NIBTS and 73% for IBTS. Wastage for these reasons (MONU and SONU) may be influenced by factors such as age of stock at issue, but also by frequency and times of delivery, distance from the blood centre and ability of hospital to store platelets. It is too early to determine if the BSMS algorithm for hospitals, for stock holding of platelets, has influenced practice and affected wastage. The algorithm is available from the website

14 8.1 Red Cell Blood Supply: England and North Wales 8.1. England and North Wales (NHSBT) Figure 1 shows the red cell supply chain using stock and wastage data taken from NHSBT participants and NHSBT. Total hospital wastage is shown as wastage as percentage of issue (WAPI) and can be seen to mirror NHSBT stock levels. This year the hospital issuable stock index (ISI) for the Very High Usage category and the Very Low Usage category has been added. The Issuable Stock Index differs greatly between the Very High usage category, where it is much lower and more constant than hospitals in the Very Low usage category, who receive only small volumes of red cells. Figure 1 Comparison between 2010/11 and 2011/12 for: Red cell stock (ISI) held in NHSBT, the total WAPI for all BSMS NHSBT hospitals. WAPI for NHSBT in 2011/12 shown, plus 2011/12 Hospital ISI for Very High and Very Low usage category Blood Service Issuable Stock Index: NHSBT The Issuable Stock Index (ISI) is a reflection of the number of days worth of stock. The NHSBT ISI has fluctuated between a high point of 10.7 in September 2011 which was the highest stock over the last 24 months. Stocks were built up for the Easter / Royal Wedding bank holiday period and the ISI remained over 10 days for that period also. The ISI had a low point of 8.4 in March 2012.

15 8.1.2 Hospital Issuable Stock Index: England and North Wales The average ISI remains variable between the hospital red cell usage categories 1 (Table 6). Very High usage category hospitals hold less stock. For all usage categories, O RhD Negative ISI is higher than the total ISI, with hospitals holding approximately an extra 2 days worth of stock. This could be due to stock held as emergency units in blood fridges outside the laboratory. The levels of stock, in terms of ISI, has remained unchanged since in any of the hospital categories. Table 6 Average ISI by hospital category for NHSBT BSMS hospitals Very High High Moderate Low Very Low All Groups O RhD Neg Red Cell Issues: NHSBT NHSBT issued 1,835,000 red cell units, between April 2011 and March 2012, a decrease on the previous year of 0.2%(cf. 1,838,500). The median number of days to expiry at issue was 21 days. This has increased by 1 day since 2010/11. The percentage of units with at least 20 days to expiry ranged from 41% in May 2011, to 65% in January 2012, similar to previous years. O RhD Negative issues to BSMS participants as a percentage of total issues was 10.6%, 0.3 percentage points higher than in 2010/11 (10.3 %). This represents an increase of 5,000 units Blood Service Wastage: NHSBT Blood service wastage is separated into two categories TIMEX and MISC. MISC wastage is composed of any unit that is available for issue and has been discarded for a reason other than time expired. Wastage as a percentage of issue is 1.1% in 2011/12. Table Total NHSBT wastage by wastage reason since 2010/11 TIMEX MISC Total WAPI % 2011/ % 2010/ % 1 Red cell usage categories are defined in the glossary

16 8.1.5 BSMS Hospitals Wastage: England and North Wales The percentage of all issues that were recorded as wasted by hospitals has decreased slightly, and was 2.2% (compared to 2.4% 2010/11). The percentage of all O Rh D Neg units that were recorded as wasted was 3.7% compared to 4.3% 2010/11, although differences in practice for discarding O RhD Neg units has been mentioned previously. Average total wastage per participant hospital for all blood groups was 160, a decrease of 12 units from 2010/11. Once again, a reduction in time expiry wastage accounts for most of this decrease in red cell wastage (Average per BSMS participant 105). Average OTCOL wastage per hospital participant is 39 units, slightly reduced from 2010/11.

17 8.2 Red Cell Blood Supply: Northern System: Northern Ireland Ireland 8.2 Northern Ireland (NIBTS) Figure 2 shows the red cell supply chain using stock and wastage data taken from NIBTS participants and NIBTS. The wastage within the blood service varies considerably during the year, which may be a reflection on the smaller numbers of both units (53,000) and hospitals (10) involved. Figure 2: Comparison between 2010/11 and 2011/12 for: NIBTS Red cell stock (ISI), Wastage as Percentage of Issue (WAPI) for all BSMS NIBTS hospitals. WAPI for 2010/11 only for NIBTS. Hospital ISI is shown for Very High and Low usage category Blood Service Issuable Stock Index: NIBTS The ISI for NIBTS is very similar year on year. Stock reduced slightly through April and May, then from an ISI of 14 in July, red cell stocks fell throughout the year to a low point in January (7.8 in January 2012). The ISI then increased sharply to a high in March of 15.2.

18 8.2.2 Hospital Issuable Stock Index: Northern Ireland The average ISI by hospital category remains variable between the hospital red cell categories. The lowest ISI is found in the Very High usage hospital category for all blood groups including O RhD Negative. The average ISI for O RhD Negative is increased for all categories, less than one day extra for Very High category usage, Moderate and Low category hold approximately 2 extra days. When compared to the previous year (2010/11) there is little change in the ISI in any of the hospital categories. Table 8 Average ISI by hospital usage category for Northern Ireland BSMS hospitals Very High Moderate Low All Groups O RhD Neg Red Cell Issues: NIBTS NIBTS issued 53,713 red cell units between April 2011 and March 2012, a increase of 0.5% when compared to 2010/11 (cf. 53,450). Red cell issues seem to be fairly constant for the last four years. The median number of days to expire at issue was 21 days in 2011/12; a increase of 1 day when compared to 20 days in 2010/11. The percentage of units issued with over 20 days to expiry ranged from 35% in March 2011 to 83% in January 2012 which reflects the NIBTS ISI range from 7.8 to 15 days stock. O RhD Negative issues as a percentage of total issues was 13.8%, 0.3 percentage points higher than in 2010/11 (13.5%) Blood Service Wastage: NIBTS Wastage is separated into two categories TIMEX and MISC. MISC wastage is composed of any unit discarded for reasons other than time expired. NIBTS MISC includes pre and post validation wastage. NIBTS blood service wastage was not collated into the BSMS database this year, due to difficulties with the transfer of this data from the NIBTS blood service IT system.

19 8.2.5 BSMS Hospitals Wastage: Northern Ireland The percentage of all issues that were recorded as wasted was 4.8%, this is the same as last year (2010/11). Average total wastage per participant hospital for all blood groups was 256 per participant, no change from 2010/11. Wastage of O RhD Negative units was recorded as 7.0% compared to 5.6% in 2010/11, although the percentage of O RhD Negative issued from NIBTS increased. Average TIMEX wastage per participant hospital for all blood groups decreased from 191 per participant in 2010/11 to 180 per participant in 2011/12, a decrease of 11 units. Average OTCOL wastage per hospital participant has also decreased in the last year, with more units being fated under the MISC category.

20 8.3 Red Cell Blood Supply: Wales 8.3 Wales (WBS) The red cell supply chain is shown below (Fig 3). Total red cell stock (ISI) held in all BSMS WBS hospitals, total stock held by WBS, and the total WAPI for all BSMS WBS hospitals and the WBS. The hospital ISI has also been added for Very High user and Very Low user categories for this year. Figure 3: Comparison between 2010/11 and 2011/12 for: Red cell stock (ISI) for WBS, the total WAPI for all BSMS WBS hospitals and for WBS. 2011/12 Hospital ISI for Very High and Very Low usage category Blood Service Issuable Stock Index: WBS For the first seven months of this year, the WBS ISI fluctuated between 5.9 and 9.0. For the following five months, ISI rose each month to a high point of 15.9 in March This was a deliberate stock build by the Welsh Blood Service, which allowed for all blood collection teams to undergo extensive training according to a pre determined schedule. 2 Red cell usage categories are defined in the glossary

21 8.3.2 Hospital Issuable Stock Index: WBS The average ISI remains variable between the hospital red cell usage categories 2 (Table 11) with the Very High use category having the lowest ISI. The Issuable Stock Index for O RhD Neg is higher than for all groups in all but the Very Low usage category. Table 11 Average ISI by usage category for WBS BSMS hospitals Very High High Moderate Low Very Low All Groups O RhD Neg Red Cell Issues: WBS The WBS issued 85,620 adult red cell units between April 2011 and March 2012, an increase of 2.1% when compared to 2010/11 (cf. 83,824). The median number of days to expiry at issue was 25 days in 2011/12 compared to 24 days in 2010/11; an increase of 1 day. The percentage of units issued with over 20 days to expiry ranged from 45% in March 2012 to 90% in September O RhD Negative issues as a percentage of total issues was 8.9%, 0.2 percentage points higher than in 2010/11 (8.7%). The Very High usage category hospitals appear to hold a large O RhD Negative stock (around 13 days) which may be due to holding emergency stock in outlying blood fridges Blood Service Wastage: WBS Wastage as a percentage of issue increased to 0.4% in 2010/11. An increase of 0.1 percentage points when compared to 2010/11. Table 12 Total WBS wastage by wastage reason TIMEX MISC Total WAPI % 2011/ / / / / /

22 8.3.5 BSMS Hospitals Wastage: WBS The percentage of all issues that were recorded as wasted by hospitals was 2.6% compared to 1.9% in 2010/11. The percentage of all O RhD Negative units that were recorded as wasted was 3.9% compared to 2.5% in 2010/11. Average total wastage per participant hospital for all blood groups was 137 per participant, which is a large increase (30 units) from 2010/11. This does seem to be mainly time expiry, and may be related to the stock build towards the end of the year. Average TIMEX wastage per participant hospital for all blood groups increased from 87 per participant in 2010/11 to 114 per participant in 2011/12, an increase of 27 units.

24 8.4.3 Red Cell Issues: IBTS The IBTS issued 138,080 adult red cell units between April 2011 and March The median number of days to expiry at issue was 26 days which gives the IBTS hospitals longer to transfuse their units than the other blood services. With a steady ISI of around 6 days throughout the year, IBTS was able to issue the majority of their units with at least 20 days to expiry, the percentage ranged from 74.5% in January 2012 to 81.4% in October O RhD Negative issues as a percentage of total issues was 14.0%. This is higher than the other blood services, but reduced from last year Blood Service Wastage: IBTS Wastage as a percentage of issue was 1.0% in 2011/12 which is slightly decreased from last year (1.2%). Table 15 Total IBTS wastage by wastage reason TIMEX MISC Total WAPI % 2011/ % 2010/ % BSMS Hospitals Wastage: IBTS Only 50% of IBTS hospitals are entering data for wastage, so an overall average WAPI can not be calculated. However, the average total wastage per participant hospital for all blood groups was 75 units per participant, with only 59 being due to time expiry. This compares favourably to hospitals supplied by other blood services, whose wastage per participant is over 100 units per year for time expiry.

25 8.5 Red Cell Blood Supply: Scotland 8.5 Scotland (SNBTS) This year, data from Scotland has been difficult to obtain due to I.T. issues. Scotland also has a separate system for monitoring stock in their hospitals Account for Blood. There are 5 hospitals who do submit data, but as issue data for the individual hospitals is not available, full analysis was not possible Blood Service Issuable Stock Index: SNBTS The reported issuable stock index averaged for the year was 8.2 days Hospital Issuable Stock Index: SNBTS Not available Red Cell Issues: SNBTS A total of 188,361 adult red cell units were issued in 2011/12 compared to 200,131 between April 2010 and March This is a decrease of 5.9% Blood Service Wastage: SNBTS The reported issuable stock index averaged for the year was 8.2 days BSMS Hospitals Wastage: SNBTS Average total wastage per SNBTS BSMS participant was 270 units (based on 5 hospitals/ centres). BSMS did not have a full set of data for the previous year, so comparison is not possible. Some detail is included in Table 17.

26 9.1 Platelet Supply: England and North Wales 9.1. England and North Wales (NHSBT) Platelets Analysis of platelet data is more complex, as not all hospitals hold stock platelets and demand planning is made more complicated by the shorter shelf life of the product. No hospital issuable stock index is available and wastage falls in to more complex categories. Figure 5: Comparison between 2010/11 and 2011/12 for: Issuable Stock Index for NHSBT and wastage (WAPI) for BSMS NHSBT hospitals. NHSBT WAPI shown for 2011/12 only Blood Service Issuable Stock Index (Platelets): NHSBT The NHSBT platelet ISI rose slightly during the year, for 5 of the last 6 months of platelet ISI greater than 2.4 days for NHSBT. Bacterial screening for platelets was introduced at the start of 2011, to prevent the possibility of bacterial transmission. This allowed the shelf life to be extended to 7 days, and this may be the cause of the increased ISI Platelet Issues: NHSBT NHSBT issued 264,800 units between April 2011 and March 2012, an increase of 9.2% from 2010/11. Much work is being done to understand this rise in platelet demand Blood Service Wastage (Platelets): NHSBT 14,422 platelet units were wasted by NHSBT, representing a WAPI of 5.4%. This has reduced from the previous year (7.2%) and could be attributed either to the increased shelf life or to the increased demand.

27 9.1.4 BSMS Hospital Wastage (Platelets): England and North Wales Platelet wastage continues to fall. The longer shelf life of platelets may be a factor, but better practice must be helping to reduce wastage in the face of increasing demand. Total hospital platelet wastage in 2011/12 was 10,704 units, a decrease of 1,125 units from 2010/11. The percentage of all issues that were recorded as wasted by hospitals was 4.0% compared to 4.8% in 2010/11. The average hospital platelet wastage per participant was 4 units lower than in 2010/11. The highest wastage occurred in the Medically Ordered Not Used category, at almost 50% of the total wastage.

28 9.2 Platelet Supply: Northern Ireland 9.2. Northern Ireland (NIBTS) This graph shows the ISI for 2011/12, which showed less variation than the previous year, plus the relationship to wastage both for the blood service and hospitals. Figure 6 Comparison between 2010/11 and 2011/12 for: Issuable Stock Index for NIBTS and wastage (WAPI) for BSMS NIBTS hospitals. NIBST WAPI shown for 2010/11 only Blood Service Issuable Stock Index (Platelets): NIBTS The NIBTS platelet ISI was between 1.1 and 1.6 for year , compared to last year when the range was wider with most months being higher, remaining above 1.5 ISI Platelet Issues: NIBTS 88,057 adult platelet units were issued by NIBTS between April 2011 and March 2012, an increase of 9.4% when compared to 2010/11 (cf. 7,366). This is similar to the rise seen in NHSBT Blood Service Wastage (Platelets): Northern Ireland Wastage data is unavailable for year 2011/2012 due to a technical issue.

29 9.2.4 BSMS Hospital Wastage (Platelets): Northern Ireland Total platelet wastage for 2011/12 was 612 units, an increase of 73 units from 2010/11. The percentage of all issues that were recorded as wasted by hospitals was 7.6% compared to 7.3% in 2010/11. The average hospital platelet wastage per participant was 7 units higher than in 2010/11. The highest wastage occurred in the Medically Ordered Not Used reason (47% of the reported wastage) but this was only slightly higher than Stock Time Expiry reason (42% of reported wastage).

30 9.3 Platelet Supply: Eire 9.3. Eire (Irish BTS) This graph shows the ISI for 2011/12, which was very comparable to the previous year, plus the relationship to wastage both for the blood service and hospitals. The overall hospitals WAPI is not shown as only 30% of IBTS hospitals enter platelet wastage data. Figure 7: Comparison between 2010/11 and 2011/12 for: Issuable Stock Index for IBTS and IBTS WAPI shown Blood Service Issuable Stock Index (Platelets): IBTS The IBTS platelet ISI peaked in December at 2.9 and had a low in May, at 2.1 with most months being close to the equivalent month ISI in the year The Christmas bank holiday peak is the main variation Platelet Issues: IBTS The IBTS issued 25,666 platelet units between April 2011 and March 2012, an increase of 6.3% compared to 2010/11 (cf. 24,137). This increase is slightly less than the other blood service issues for year , but is still a substantial increase Blood Service Wastage (Platelets): IBTS 2,722 platelet units were wasted by IBTS representing a WAPI of 10.6%, a decrease from last year which was 14.2%. The spikes in wastage around bank holiday periods in August and December were not as marked or as prolonged as last year s data indicated.

31 9.3.4 BSMS Hospital Wastage (Platelets): IBTS Hospital platelet wastage for 2011/12 was 481 units (12 hospitals submitting data). For total numbers the average per hospital submitting data, is very similar to last year. Looking at the hospital wastage, the highest wastage category was Surgically Ordered Not Used (SONU) category, both last year and this year. However the number of platelets discarded as STEX (stock time expiry) has reduced, and there has been a rise in the number of units ordered for medical patients and not used (MONU). The time expiry of stock platelets as a wastage category accounted for 21% of wastage reported, compared to 73% for MONU and SONU wastage categories combined.
