8. What remains to be done before each component of the BSCP is fully operational? |
TTISS
TESS
CTOSS
Linkages with PHINs
Risk identification for High Risk Populations
|
There are a variety of tasks remaining before each of the BSCP components is fully operational. For TTISS, it will be necessary to ensure adequate participation of the provinces and territories, and more timely reporting. For TESS, additional sites need to be recruited, and reporting carried out at the national level. CTOSS is still in the planning stages, so much still remains to be done. Linkages with public health have begun, but need to be fostered more consistently. The blood sample archive exists, but further testing of the samples is needed before this component becomes useful.

9. / 10. What progress has been made towards the intermediate and long-term outcomes of the BSCP? |
Risks have been identified, assessed, and mitigated for transfusion-related adverse events/errors. Mitigating strategies include the development of guidelines for investigation of suspected bacterial contamination and guidelines for identifying TACO and TRALI. Risks have not yet been identified, assessed, and mitigated for transplant-related adverse events/errors.Risks for high risk populations have reportedly been identified, assessed, and mitigated for transfusion-related adverse events, but no specific examples were provided. Risks have not yet been identified, assessed, and mitigated for transfusion-related errors or transplant-related adverse events/errors. |
Identify/Assess Risks and Develop Mitigating Strategies
BSCP data have enabled the identification and assessment of risks associated with the use of blood and blood products, and the development of mitigating strategies. The majority of survey respondents indicated that they had used the data for this purpose, and reported that it would have been more difficult without the BSCP data. Two specific examples are:
- The development of a Guideline for Investigation of Suspected Transfusion Transmitted Bacterial Contamination (2008), which should enable health care workers to identify sources of bacterial contamination more quickly, and thereby take action to quarantine products from the same source, or assess and treat other recipients of products from that source.
- The development of a set of guidelines or an algorithm for identifying Transfusion Associated Circulatory Overload (TACO) and Transfusion Related Acute Lung Injury (TRALI), which will help physicians recognize and treat these adverse events more quickly.
Because CTOSS is in such an early stage of development, there have not yet been opportunities to identify and assess the risks associated with transplantation of cells, tissues and organs.
Identify/Assess Risks and Develop Mitigating Strategies for High Risk Populations
A small proportion of key BSCP stakeholders have used the TTISS data to identify, assess, and mitigate risks for high risk populations. However, the evaluation did not uncover specific examples of how the data were used. The blood sample archive has not yet been used for this purpose.
Because CTOSS is in such an early stage of development, there have not yet been opportunities to identify and assess the risks associated with transplantation of cells, tissues and organs.

11. Have there been any unintended (positive or negative) outcomes of the BSCP activities? If so, what are they, and what actions were taken as a result? | Positive
Negative
|
Some positive unintended outcomes of the BSCP are international recognition for Canada as a leader in hemovigilance, the development of communication networks within the country, and improved identification of adverse reactions by health care practitioners. No negative unintended outcomes were identified by the evaluation.
Stakeholder perceptions, combined with observed relationships between availability of funding and implementation of surveillance systems, suggest that the BSCP likely contributed to the development and implementation of surveillance systems for transfusion-related adverse events and errors. Although some regions might have developed these systems without the BSCP, this may not have happened as quickly or as comprehensively.
Stakeholders believed that it would be more difficult to identify, assess, and mitigate risks related to transfusion of blood and blood products without the TTISS and TESS data.
In 2007-2008, the annual program budget was approximately $3.92 million, including contributions, staff salaries, and operations costs. As described in the answers to evaluation questions 7, 9, and 10, a considerable amount has been achieved with BSCP program dollars to date.
The cost of administering the program is approximately 40% of the total program cost, based on program budgets. The program does not usually distribute all of the available funds, in part because of delays in signing the contribution agreements and in part because of the PHAC annual budget reduction exercise. The amount varies from year to year, from 63% of the approved funds being distributed (in 2006-07) to 87% (in 2007-08).
Although it is not possible to draw any definitive conclusions about the efficiency of Canada’s system compared with those in other countries, supposition and anecdotal information indicate that Canada has achieved an internationally recognized system with relatively few funding dollars. Stakeholders also indicated that the BSCP provided good value for money. Very few suggestions for improving efficiency were provided.
To determine the resource requirements for sustaining a surveillance system appears to be challenging, as no formal long-term commitments are present from any of the parties involved. In addition, it is unclear exactly what the resource requirements may be for maintenance of TTISS, and what activities and outputs are required in the long-run for TESS and CTOSS.
The provinces and territories participating in TTISS anticipated that the annual overall costs of maintaining the TTISS system may actually be higher than the annual costs during the initial implementation of the system, possibly because of inflation and the costs of updating the system. The provinces and territories represented in the survey estimated that they would need a total of about $1.2 million per year in BSCP funding to maintain TTISS.
