A survey of nurses to assess transfusion practice at the bedside using an electronic identification system: Experience at a university hospital

Questionnaire Survey on Current Red Blood Cell Transport and Storage in Korea for Reducing Wastage

Background

To ensure safe red blood cell (RBC) transfusion practice, it is important to comply with storage and transport requirements of RBC units. We conducted a comprehensive survey on the practice of RBC transport and storage to explore the awareness of and compliance with the 30-minute rule, the current status of RBC unit transport, and possible utility of temperature indicators (TIs) to reduce RBC wastage.

Methods

From June to August of 2019, 64 blood bank physicians (14 questions) in 64 secondary- and tertiary-care hospitals and 673 nurses (13 questions) in 42 tertiary-care hospitals replied to a questionnaire survey. The results of the survey were analyzed with descriptive statistics.

Results

Among the physicians surveyed, 97.0% (N=62) of hospitals had transfusion guidelines in place. The RBC wastage in 2018 ranged from less than five units to more than 200 units. Among the nurses surveyed, 99.4% (N=669) were aware of and complied with the 30-minute rule; 13.5% (N=91) of the nurses had experience of RBC wastage due to violation of the 30-minute rule. Both physicians (67%, N=43) and nurses (83.1%, N=559) responded that TIs would help reduce RBC wastage.

Conclusions

This is the first survey on the practices related to RBC transport and storage in Korea. This study provides fundamental data on current practice for the blood cold chain, insights into RBC wastage, and highlights the utility of TIs.

Sample collection for pre-transfusion crossmatching: Benefits of using an electronic identification system

BACKGROUND

Transfusion of ABO blood group-mismatched blood or administration to the wrong recipient may result in fatal adverse events. To prevent these types of errors, various strategies have been employed. Recently, we developed a novel sample collection workflow for the pre-transfusion crossmatching test and patient recognition. This study aimed to analyse the usage of the new workflow and improvements in outcomes.

METHODS

We analysed the number of crossmatching and wrong-patient errors among the blood transfusion cases during 3 years of data collection (from August 2018 to July 2021). From May 2021 to July 2021, the new workflow was implemented. Outcomes were calculated according to the department type, patient age and processing time. The sample processing time was defined as the time from placing the order to lab arrival.

RESULTS

The new workflow utilisation increased from 50.7% to 80.3% and wrong-patient errors decreased annually. The new workflow was used for more adults (3001/3680 samples, 81.5%) than paediatric cases (345/522 samples, 65.5%; p < 0.001) and in general wards than in the emergency room or intensive care unit. The sample processing time differed according to ward type and timing of the request (day: 28.80, 2.43-3889.43 min, night: 3.36, 2.72-1671.47 min; p < 0.001).

CONCLUSION

Wrong-patient errors were reduced without increasing sample-processing time after introducing the new workflow which included using an electronic identification system. The time needed for the blood processing differed according to the ward type, patient age, and timing of the request. Patient safety can be promoted by managing these factors and using an electronic identification system.
