Investigating the quality of hemovigilance process using the first two steps of Six Sigma model: a cross-sectional study.

BACKGROUND AND PURPOSE: Hemovigilance is a set of monitoring methods that covers the blood transfusion chain, from collecting blood and blood products to monitoring the blood recipients. To this end, any error in this process can have serious and irreparable consequences for patients. The present study aimed to investigate the quality of hemovigilance process in Iran, using the first two steps of Six Sigma model. METHODS: This was a quantitative cross-sectional study that was conducted over 6 months (from August 20, 2021, to February 20, 2022) at Afzalipour Hospital in Iran, using the first two steps of Six Sigma model. The study population comprised of all inpatients who needed blood or blood product transfusion in various departments of Afzalipour Hospital, among whom 477 patients were selected via stratified sampling in three shifts (morning, evening, and night). The datasheet was used to record errors in the three shifts. This research was conducted, using the DMAIC cycle's "define" and "measure" steps. RESULTS: In the define step, the hemovigilance process at Afzalipour Hospital was divided into two categories of normal process and emergency process. Each of these processes consists of several sub-processes, including "phlebotomy," "requesting blood and blood products from the department," "preparation of application by the blood bank," " sending a request from the blood bank to the blood transfusion center," "transfusing blood and blood products," and "returning the blood and blood products to the blood bank and waste disposal." In the measure step, the quality of hemovigilance process was evaluated based on sub-processes and labels at morning, evening and night shifts. The sub-process of sending a request from the blood bank to the blood transfusion center had the highest error rate with a sigma level of 1.5. Also, the evening and night shifts had a sigma level of 1.875, and the clinical and registration labels had a sigma level of 1.875. The overall sigma level of hemovigilance process was calculated to be 2. CONCLUSION: The results of this study showed that the quality of hemovigilance process at Afzalipour Hospital was poor. By employing the first two steps of Six Sigma method, we identified the existing errors in the hemovigilance process of Afzalipour hospital in order to assist hospital managers to take the necessary measures to improve this process.

Blood and blood products transfusion errors: what can we do to improve patient safety?

Evidence suggests that blood transfusion errors tend to occur because of an external stimulus, limiting control for the professional administering it. Whether it be cognitive bias, human traits, organisational or human factors, errors should be prevented because they put the safety of the patient at risk from major morbidity and mortality. The authors explored the literature that looked at the blood transfusion errors that occur, suggesting interventions that may have a positive impact on patient safety. A review of the literature was undertaken using key words and limiters to focus the search. The review found that, when practitioners do not perform skills or interventions regularly, competence diminishes. Training and rolling refresher programmes appeared to improve retention and knowledge, therefore enhancing patient safety. Consequently, the impact of human factors in the healthcare setting requires more comprehensive investigation. Nurses may have the knowledge and understanding regarding blood transfusions; however, the environment in which they work could contribute to the likelihood of errors.
