Surveys and audits

Reports about the blood supply chain and inventory management

Inventory practice surveys/audits

We aim to distribute an annual inventory practice survey to all participants on various aspects of hospital blood inventory management. Participation in the surveys is voluntary.

A number of surveys have been conducted since 2001 including:

  • Red cell ordering and practice, laboratory staffing and maximum surgical blood ordering schedule
  • Use of the BSMS and crossmatch practice
  • Group substitution (mismatching)
  • Platelets and laboratory working practice
  • Blood storage – fridges and alarms
  • Frozen components and laboratory working practice

The information from the surveys is analysed and reports distributed to those that have participated.

We have also performed a number of audits in collaboration with hospitals, in order to identify areas of best practice and inform future work.

2023 Hospital Frozen Component Inventory Practice Survey 

This inventory practice survey aimed to gain a better understanding of current hospital frozen component stock practices for NHSBT served hospitals. The intention was to establish current hospital procedures to understand the trend in data, inform future collection and manufacturing models and identify best practice recommendations.

2021 Hospital Platelet Inventory Practice Survey

This year’s inventory practice survey was centered around gaining a better understanding of current hospital platelet stock practices for NHSBT served hospitals. Its intention was to establish a full picture of the scope and variation of current procedures to better inform future collection and manufacturing models and to identify best practice models to help support others and where possible formulate some best practice guidance.

Audit of Data Entry 2023


An evaluation of Vanesa Hospital Data Entry

Whilst BSMS data entry isn’t mandated, it is considered good practice. Hospital data is valuable to the blood service and to hospital peers participating in the BSMS to enable good inventory management practices and help blood services maintain a consistent supply through using real hospital data. This evaluation of hospital data entry is intended to encourage hospitals to review and improve their data entry.
