Blood Transfusion Practice among Healthcare Personnel in Nepal: An Observational Study

Pattern and clinical correlates of renal iron deposition in adult beta-thalassemia major patients

We evaluated pattern and clinical correlates of renal T2* measurements in adult β-thalassemia major (β-TM) patients. Ninety β-TM patients (48 females, 38.15 ± 7.94 years), consecutively enrolled in the Extension-Myocardial Iron Overload in Thalassemia network, underwent T2* magnetic resonance imaging (MRI) for quantification of iron overload (IO) in kidneys, liver, pancreas, and heart. Ten (11.1%) patients showed renal IO (T2* < 31 ms). Global kidney T2* values did not show a correlation with gender, age, splenectomy, regular transfusions or chelation starting age, pre-transfusion hemoglobin, and serum ferritin levels. Global kidney T2* values showed an inverse correlation with MRI liver iron concentration (LIC) values (R = - 0.349; p = 0.001) and a positive correlation with global pancreas T2* values (R = 0.212; p = 0.045). Frequency of renal IO was significantly higher in patients with cardiac IO than in patients without cardiac IO (50.0% vs. 6.3%; p = 0.001). A significant inverse association was detected between global kidneys T2* values and lactate dehydrogenase (LDH) (R = - 0.529; p < 0.0001). In multivariate regression analysis, MRI LIC and LDH were the strongest predictors of global kidney T2* values. A MRI LIC > 4.83 mg/g dw predicted the presence of renal IO (sensitivity = 90.0%; specificity = 61.2%). Global kidney T2* values were inversely correlated with uric acid (R = - 0.269; p = 0.025). In conclusion, in adult β-TM patients, renal iron deposition is not common and is linked to both hemolysis and total body iron overload.

Improving nurses' blood transfusion knowledge and skills

The World Health Organization (2019) has determined that patient safety is a global public health challenge. In UK clinical areas, policies and procedures are in place for the safe prescribing and delivery of blood and blood product transfusions, yet patient safety incidences continue. Undergraduate nurse education and training may provide the underlying knowledge to practitioners, while postgraduate standalone training sessions support skill development. However, over time, without regular experience, competence will diminish. Nursing students may have little exposure to transfusion practice and COVID-19 may have exacerbated this challenge with a reduction in placement availability. The use of simulation to support theory with follow-up and ongoing drop-in training sessions may help to inform practitioners and improve patient safety in the management and delivery of blood and blood product transfusion.

Assessment of the Key Performance Indicator Proposed by NABH in the Blood Centre of a Tertiary Health Care Hospital in Southern India

Quality indicators are tools for continuous improvement to enable the blood center to achieve its standards of the highest quality. Hence, they have to be established and monitored regularly for which NABH (National Accreditation Board for Hospitals) accreditation should be sought for. This study was undertaken to assess the Key Performance Indicators (KPI) through clinical audit quality control study of ten parameters, with a goal to improve and meet the benchmark as defined by NABH. All 10 Key Performance Indicators defined by NABH were analysed prospectively in a tertiary care blood centre of southern India. Parameters were compared to that of bench mark standards. Root cause analysis of all non-conformance parameters were done. Problem were identified and action taken to achieve KPI benchmarks in all deviations. Out of the ten KPI's which were studied, more than 50% meet the quality standards. The ones that did not meet the bench mark were TTI-HIV% which was 0.44%, TTI-Syphilis (RPR)% 0.26%, Number of units received back for discarding 5.96%, PRBC wastage% (on-shelf) was 2.11%, FFP, Cryoprecipitate wastage % (on-shelf) was 2.71%, the mean TAT for crossmatch of emergency PRBC blood was 18.3 min, 41.11% of FFP QC failure failed, Delay in transfusion time beyond 30 min after issue was 19.14%, Donor Deferral rate was 16.36% and TTI Outliers% No. of deviations beyond ± 2SD for HBsAg, HCV, HIV were 14.43%, 12.59% and17.73% respectively. Present study has helped to understand the flaws and problems faced by a tertiary care blood center in sustaining quality. It also actively captured and analysed multiple cross sections of non-conformances.

A prospective interventional study to assess the impact of a 'structured compact training' on knowledge and skills of safe blood transfusion practices among nurses working in a tertiary care institute

INTRODUCTION

There is scarce information on the baseline knowledge and practices of nursing officers in relation to administration of blood components. We set out to evaluate the influence of training on their knowledge and skills through Kirkpatrick's levels of Training Evaluation.

MATERIALS AND METHODS

This interventional cross sectional study of 7 months duration conducted in a tertiary care teaching institute involved 200 nursing officers. Hundred were assigned to study/intervention group and 100 were assigned to control/ comparison group by systematic random sampling. Knowledge was tested in different domains-blood components, pre-transfusion checks, transfusion process, post-transfusion process and blood administration practice.

RESULTS

The baseline knowledge scores of intervention and control group were similar-15.16 ± 4.11 and 15.02 ± 4.75 (p = 0.831). Post-intervention (phase I) after 1 month, the scores improved significantly for domain A, B, C, D and E to 4.3 ± 2.21 (p = 0.0001), 3.46 ± 2.15 (p = 0.0001), 7.02 ± 3.55 (p = 0.0001), 2.51 ± 1.46 (p = 0.0012), and 5.86 ± 3.61 (p = 0.0018) respectively. In phase II, after 3 months of training, and the scores were significantly better from baseline for all domains except E. For domain A, B, C, D and E, scores were 3.82 ± 2.46 (p = 0.0001), 3.53 ± 1.98 (p = 0.0001), 7.38 ± 3.87 (p = 0.0001), 2.48 ± 1.55 (p = 0.0035), and 5.86 ± 3.61 (p = 0.95) respectively.

CONCLUSIONS

Our study showed that baseline scores were low in the nursing officers. No significant difference was found in baseline scores in subject and control population. However, post-intervention, a significant improvement in scores was observed in the study group across all domains.

Safe Blood Transfusion Practices among Nurses in a Major Referral Center in Ghana

Errors in transfusion of blood and blood products can lead to preventable morbidity and mortality. Nurses constitute a significant aspect of the transfusion process as they are the last in the chain of getting blood directly to the patient. They must, therefore, be conversant with the current standard of national and international guidelines on blood transfusion and appropriate management of adverse transfusion events. This study assesses the knowledge and practices of blood transfusion safety among nurses at Komfo Anokye Teaching Hospital. A descriptive cross-sectional design was employed, and structured questionnaire (Routine Blood Transfusion Knowledge Questionnaire) was used to collect data from 279 nurses from seven clinical directorates of the hospital. The data were processed with Stata version 14.0. Variables were analyzed using descriptive statistics, and relationships were drawn using inferential statistics. Over 90% of the respondents had a minimum of a diploma in nursing or midwifery, 63% had performed blood transfusion at least 5 times, and 46% had never received any training on blood transfusion. The mean score obtained in all four categories of blood transfusion knowledge assessed was 29, with 54% of the respondents scoring below the mean. The highest overall score on knowledge was 53%. This indicates that nurses had poor knowledge regarding safe blood transfusion practices as stipulated in the clinical guidelines for blood transfusion by Ghana's National Blood Service. There was no statistically significant relationship between training/experience and knowledge of safe blood transfusion practices. Regular and continuous update training and audit are needed to safeguard patient safety during blood transfusion.

Knowledge Improvement of Blood Transfusion Safety Among Pediatricians: Post Educational Intervention

Human factors account for most reported errors in the serious hazards of blood transfusion report, thus staff training on safe blood transfusion is strongly recommended. This study aimed to assess knowledge of blood transfusion safety among pediatricians and determine the impact of an educational initiative. A quasi-experimental study was conducted on 190 pediatricians. A questionnaire was designed and validated through a pilot study after which all participants were invited to fill it pre- and posteducational intervention. The educational material has been prepared based on the WHO blood transfusion safety guidelines; prepared by the researcher and reviewed by experts in the field. Near miss was identified by 47% of the participants and around 78.3%, 63.2%, and 60% of them correctly identified the indication of red blood cells, fresh frozen plasma, and platelet transfusion. These percentages were significantly improved post education. Only 55% knew that it's not allowed to co-administer drugs or IV fluids with the transfused blood and that rose to almost 80% after intervention. Consent information and correct patient identification were well known among most of them. Only 18.4% knew the pre transfusion screening protocol, which was increased to 85.8 % posteducation. Almost 65.3% correctly responded to the transfusion reaction quiz with no significant change after intervention. Age and work experience were significant independent risk factors for poor knowledge of transfusion safety. Transfusion safety knowledge needs further enhancement with more tailored training programs focusing on the topics that did not show a significant change after our educational training.

Bedside Blood Transfusion - What Nurses Know and Perform: A Cross-Sectional Study from A Tertiary-Level Cancer Hospital in Rural Kerala

Objective:

Nursing professionals are expected to have updated knowledge of clinical blood transfusion guidelines while catering to cancer patients requiring bedside transfusions.

Methods:

A cross-sectional study was conducted to evaluate the knowledge and current practice of nurses at a tertiary-level cancer hospital in rural Kerala using a pretested self-administered structured 20-item questionnaire, and results were analyzed.

Results:

Among 246 nurses who participated, a response rate of 93.08% (n = 229) was obtained. Mean scores of 4.64 ± 1.20 out of eight for knowledge-based questions (58.00%) and 6.16 ± 1.49 out of 12 for practical aspects (51.33%) were obtained among respondents. Whereas overall scores were fair (84.28% and 65.94% nurses scoring ≥50% in knowledge-based and practice-based questions, respectively), we noticed poor knowledge-level scores for the key aspects such as time taken for cross-matching, cross-match test taking least time, storage temperature, and mandatory transfusion-transmitted infection tests before initiating transfusion. Poor scores were also noted for key clinical practices relating to warming of blood products, posttransfusion patient monitoring, rate of nonemergency blood transfusions, administration of premedications, and disposal of blood bags among the respondents. Data also revealed that there was a lack of adherence to a uniform cannula size for routine blood transfusion among nurses. Work experience or qualification had no significant relation to the nurses' scores for knowledge or practice-based questions.

Conclusions:

Overall, a fair amount of theoretical and practical knowledge about bedside transfusion practices were observed among nurses with some inconsistencies not related to qualification or work experience. This illuminates inherent lacunae in the existing training system and merits urgent redressal.

Effect of warming and infusion of red blood cell concentrates on markers of haemolysis: An ex vivo simulation study

BACKGROUND

Transfusion of red blood cell (RBC) concentrates is a common procedure to restore blood volume and tissue oxygen delivery in patients with trauma. Although RBC warmers may prevent hypothermia, some warming or infusion equipment may lead to haemolysis and patient injury.

OBJECTIVES

The aim of this study was to test the effect of (i) RBC warming and (ii) administration via manual vs. pump infusion on haemolysis.

METHODS

This experimental ex vivo study studied haemolysis markers of RBC injury. The sample consisted of 90 RBC infusions in two simulations, randomly, 45 warmed RBC infusions and 45 nonwarmed RBC infusions, in two or three stages: before the intervention (baseline-warming, N= 45; nonwarming, N= 45), after water bath warming at 42 °C (warmed, N= 45), and then after the warmed or nonwarmed RBCs were infused by manual or pump infusion at a rate of 100 mL/h (infusion-warming, N= 45; nonwarming, N= 45).

RESULTS

Warmed RBCs showed significantly lower total haemoglobin (Hb) and haematocrit levels and increase in free Hb levels, haemolysis levels, and lactate dehydrogenase (LDH) activity (all p<0.05) than baseline RBCs. Pump infusion RBCs were associated with reduced total Hb and increased free Hb, haemolysis, and potassium (K) levels (all p<0.05) compared with warmed RBCs. In contrast, manual infusion of warmed RBCs resulted in significantly reduced total Hb levels and increased LDH activity (both <0.05). After infusion, total Hb, free Hb, haematocrit, haemolysis, and LDH values were significantly different for warmed vs. nonwarmed RBCs (p<0.05).

CONCLUSIONS

Haemolysis biomarkers increase with RBC warming and infusion, especially when using infusion pumps. Critically ill patients should be carefully monitored for possible complications during and after RBC infusion.

Using Failure Mode and Effects Analysis in Blood Administration Process in Surgical Care Units: New Categories of Errors

BACKGROUND

Blood administration failures and errors have been a crucial issue in health care settings. Failure mode and effects analysis is an effective tool for the analysis of failures and errors in such lifesaving procedures. These failures or errors would lead to adverse outcomes for patients during blood administration.

OBJECTIVES

The study aimed to: use health care failure mode and effect analysis (HFMEA) for assessing potential failure modes associated with blood administration processes among nurses; develop a categorization of blood administration errors; and identify underlying reasons, proactive measures for identified failure modes, and corrective actions for identified high-risk failures.

METHODS

A cross-sectional descriptive study was conducted in surgical care units by using observation, HFMEA, and brainstorming techniques. Prioritization of detected potential failures was performed by Pareto analysis.

RESULTS

Eleven practical steps and 38 potential failure modes associated with 11 categories of errors were detected in this process. These categories of errors were newly developed in this study. In total, 17 of 38 potential failures were detected as high-risk failures that occurred during the sample-drawing, checking, preparing, administering, and monitoring steps. For cause analysis of failures and errors, proactive suggested actions were undertaken for 38 potential failure modes, and corrective actions for 17 high-risk failures.

CONCLUSION

HFMEA is an efficient and well-organized tool for identification of and reduction in high-risk failures and errors in the blood administration process among nurses without building punitive culture. This tool also helps pay attention to redesigning and standardizing the blood administration process as well as providing training and educational programs for providing knowledge.
