Profile of blood donors and reasons for deferral in coastal South India

A Questionnaire Study to Assess the Belief and Barrier to Blood Donation and the Influence of Educational Intervention on Urban and Rural Patients

OBJECTIVE

 Blood transfusion services are an essential part of any healthcare delivery system in today's clinical world with advanced medicines because blood is in high demand during various medical emergencies. Improving knowledge and hastening the development of a positive attitude toward blood donation in society should be the goal of developing an efficient strategy for sustaining a safe and adequate blood supply.

AIM

 The study aims to explore the knowledge, attitude, and motivation toward blood donation among urban and rural patients attending the outreach program.

MATERIALS AND METHODS

 Patients who attended the outreach program held by the Dental College of Uttar Pradesh were subjected to a questionnaire survey to determine their level of knowledge regarding blood donation. Further, an education-based intervention was done among the camp patients to assess the change in their learning after the intervention. The difference between the individual responses prior to and following the intervention was analyzed using the chi-square test. p≤0.05 was considered statistically significant.

RESULTS

 Urban patients comprise 186 males (44.28%) and 234 females (55.72%). Among the rural patients, 205 (45.55%) were males and 245 were females (54.45%). About 48.80% of the urban patients and 48.88% of the rural patients were Hindus while the remaining were Muslims. Only 22.14% of urban patients and 16.88% of rural patients had donated blood till now. The comparison after the intervention for rural patients showed a significant improvement in the level of knowledge and awareness.

CONCLUSION

 Although it is quite common knowledge that rural people require more awareness and education related to health, after the conduction of our study, we have resolute evidence that demands thorough IEC and health information activities for the welfare of rural people and to diminish the divide.

Analysis of reasons of blood donor deferral at a tertiary care institute in India and its reflections on community health status

INTRODUCTION

Safe blood donors form the backbone of safe blood transfusion services.[1] Donor eligibility policies are a critical layer of blood safety designed to ensure selection of healthy donors and to protect recipients from any harm. This study was planned to analyze the pattern of whole blood donor deferrals and its characteristics and reasons at a tertiary care institute in northern India, as the pattern varies according to epidemiology of diseases in different demographic areas.

MATERIALS AND METHODS

It was a cross-sectional study of 2 years' duration from December 2015 to November 2017. The data of the potential donors who were deferred were recorded on a separate pro forma which included their demographic details, type of donation - voluntary donor and replacement donor; first time and repeat donor; type of deferrals (permanent and temporary); and the reasons of deferrals.

RESULTS

A total of 3133 donors (voluntary - 1446 and replacement - 1687) donated and 597 donors were deferred (deferral rate - 16%) during this period. Majority of the deferrals, i.e., 525 (88%) were temporary, while 72 (12%) were permanent. The most common reason of temporary deferral was anemia. The most common reason of permanent deferrals was a medical history of jaundice.

CONCLUSIONS

Our study results indicate that the blood donor deferral can have subtle variations based on regional aspects that should be considered when national policies are developed as pattern of deferral varies according to the epidemiology of diseases in different demographic areas.

Prevalence and Association of Transfusion Transmitted Infections with ABO and Rh Blood Groups among Blood Donors in the Western Region of Saudi Arabia: A 7-Year Retrospective Analysis

This study was aimed at determining the prevalence estimate and association of transfusion-transmitted infections (TTIs) with ABO and Rh blood groups among blood donors at the King Faisal Specialist Hospital and Research Center (KFSH & RC) in the western region of Saudi Arabia. A retrospective study was conducted at the blood bank center of KFSH and RC from 1 January 2013 to 31 December 2019. Data on ABO and Rh blood group testing, serological testing, molecular investigations, serological assays, nucleic acid testing (NATs), and socio-demographic information were gathered. During the study period, there were 959,431 blood donors at the KFSH and RC. The overall 7-year cumulative prevalence estimate of blood transfusion-transmitted infections among blood donors was low at 7.93%, with an average prevalence estimate of 0.66%. Donors with the O blood group, the O RhD +ve blood group, in particular, were more at risk of developing TTIs, whereas donors with the AB blood group, the AB RhD −ve blood group, in particular, were at the lowest risk of developing TTIs. In total, 96.9% of the blood donors were males (n = 916,567). Almost half of the blood donors belong to the O blood group (49.4%). A total of 861,279 (91.0%) donors were found to be RhD positive. The percentages of TTIs were found to be higher in RhD +ve donors compared with RhD −ve donors. The prevalence estimate of the hemoglobin C (HbC) infection was the most common TTI among the blood donors being 3.97%, followed by malaria being 2.21%. The least prevalence estimate of TTI in the present study was for NAT HIV being 0.02%. Significant associations were observed between RhD +ve and RhD −ve among the malaria-infected donors (A: χ2 = 26.618, p = 0.001; AB: χ2 = 23.540, p = 0.001; B: χ2 = 5.419, p = 0.020; O: χ2 = 68.701, p = 0.001). The current 7-year retrospective study showed a low level of TTIs among blood donors. However, we urge that more research encompassing the entire country be conducted in order to obtain more representative results in terms of the prevalence estimate and association of transfusion-transmitted infections with ABO and Rh blood groups in communities.

Reinduction of the Temporarily Deferred Donors for Laying the Foundation of Safe and Sustainable Blood Supplies: A Review in the Indian Context

Temporarily deferred donors are a forgotten pool of potential blood source. When dealt appropriately, they can easily be inducted back to the main stream pool of voluntary donors. Although there are multiple studies from India on the deferral rates and patterns; not much has been done with respect to the follow up of these donors and active efforts to bring them back to donate blood. In this narrative review, we discuss the impact of temporary deferral, factors affecting the return and appropriate strategies to improve the return rate of these donors.

Sero-prevalence ABO and Rh blood groups and their associated Transfusion-Transmissible Infections among Blood Donors in the Central Region of Saudi Arabia

BACKGROUND

Screening of blood products is considered a mandatory protocol implemented in health care facilities in order to reduce the onset of transfusion-transmitted infections (TTIs). This study was aimed to determine the sero-prevalence of ABO and Rh blood groups and their associated TTIs among blood donors in the Central Region of Saudi Arabia.

METHODS

This was retrospective study performed on the blood donors' records from March 2017 to December 2018 at Buraidah Central Hospital Blood Bank. Study was conducted on a total of 4590 blood donors. ABO and Rh typing was performed.The blood samples were also screened serologically for hepatitis B surface antigen (HBsAg), anti-hepatitis B core total antibodies (anti-HBc total), hepatitis C virus (HCV), human immunodeficiency viruses (HIV), human T-lymphotrophic virus-1 (HTLV-1) and veneral disease research laboratory test(VDRL) for syphilis.

RESULTS

Out of 4590 blood donors, O positive blood group was found to be highest (42%), followed by A positive (23.4%), B positive (20.9%), O negative (5.45%), AB positive (3.4%), A negative (2.8%), B negative (2.1%) and AB negative (0.5%). Moreover, total number of Rh-negative donors was significantly lowered as compared with Rh-positive. Seroreactive tests were found to be positive in only 1.002% of all studied donors and mainly found in male donors. Among TTI, anti-HBc total was the highest (0.784%), followed by HBsAg, HCV, VDRL and TPHA. Whereas all tested donors were found to be negative for HIV infections.

CONCLUSIONS

The information collected for the frequency of ABO blood phenotypic groups has a vital significance in establishing a simple blood group database. This study clearly determined significantly lower rate of seropositive TTIs among the studied blood donors but still steps are needed to improve the knowledge and to prevent the seropositive occurrence of TTIs.

Impact Analysis of the National Guidelines for Blood Donor Selection in India: A Single Center Study

National Blood Transfusion Council recently released the national guidelines for blood donor selection in India. Some changes in the currently used donor selection criteria have been proposed. However, its effect on future donor availability and deferral has not been studied. To enumerate the changes in current donor selection criteria and analyze its impact on the future blood donor availability vis-à-vis current deferral rate. One year data for both selected and deferred whole blood donors was analyzed retrospectively. Questionnaire forms of the selected donors were screened to analyze the responses given at the time of donation. A total of 4494 donors presented for whole blood donation and 995 (22.1%) were deferred for the various reasons. NBTC has proposed 12 major changes in the currently used donor selection criteria with 11 resulting into increased deferral of the blood donors. These changes would lead to an additional deferral of 32.5% of the currently eligible blood donors mostly due to the change in the blood pressure cut off. National blood donor selection guidelines in the current form would lead to a very high deficit of available blood donors in India. There is an urgent need to reconsider the merit of the changes suggested in these guidelines.

Potential Implications of Detecting HBsAg in Asymptomatic People in an Endemic Community Through Medical Camps

BACKGROUND

In a developing country like India with intermediate level of prevalence of hepatitis B, most of the patients remain undiagnosed as they are asymptomatic. The purpose of the study was to diagnose asymptomatic HBsAg positive patients from the general population and evaluate further the potential clinical implications of IDAHS.

METHODS

Asymptomatic subjects with unknown HBV status were screened free of cost for hepatitis-B surface antigen. Those who tested positive for HBsAg were further tested to identify those who were potential candidates for anti-viral therapy. To explore the relevance of our screening we assessed potential implications of HBsAg detection.

RESULTS

A total of 30,836 patients were screened in medical camps over the period of 7 years. Out of these 704 (2.3%) subjects were found to be positive for HBsAg. Distress of being diagnosed with HBV was expressed by 649 (92%) of the positive subjects. High cost of further testing and antiviral therapy, leading to inability to pursue further management was elicited in 510 (72%) of the positive subjects. HBV DNA was detected in 349 (59%) out of 592 subjects, out of which 236 (67%) had high viral load.

CONCLUSION

Incidental detection of asymptomatic HBsAg positive subjects was seen in 2.3% of subjects. One third of these patients had an actively replicating virus and required antiviral therapy. Financial support was required in 72% of the subjects for further HBV management. Detecting HBsAg in asymptomatic person in an endemic community has considerable health and psycho-economic impact on the individual.

Seroprevalence of transfusion-transmissible infections (HBV, HCV, syphilis and HIV) among prospective blood donors in a tertiary health care facility in Calabar, Nigeria; an eleven years evaluation

Background

Provision of constant and safe blood has been a public health challenge in Sub-Saharan Africa with high prevalence of transfusion-transmissible infections (TTIs). This study was aimed at determining the trend and seroprevalence of HBV, HCV, syphilis and HIV across the years within study among prospective blood donors at blood bank in University of Calabar Teaching Hospital (UCTH), Calabar, Nigeria.

Methods

A retrospective analysis of blood donor data from January 2005 to December 2016 was conducted in Blood Bank/Donor Clinic of University of Calabar Teaching Hospital, Calabar, Nigeria. Sera samples were screened for hepatitis B surface antigen (HBsAg), antibodies to hepatitis C virus (HCV), human immunodeficiency virus (HIV) 1 and 2 and Treponema pallidum using commercially available immunochromatic based kits.

Results

Out of the 24,979 screened prospective donors in the 2005–2016 study period, 3739 (14.96%) were infected with at least one infective agent. The overall prevalence of HBV, HCV, syphilis and HIV were 4.1, 3.6, 3.1 and 4.2%, respectively. During the period of study, the percentage of all transfusion-transmissible infections declined significantly with remarkable decline in HIV. The study showed male dominated donor pool (98.7%) with higher prevalence (4.2%) of transfusion-transmissible infections than in female donors (0.0%). Commercial donors constituted majority (62.0%) of the donors and as well had the highest prevalence of transfusion-transmissible infections. Majority (62.9%) of the donors were repeat donors.

Conclusion

HBV, HCV, syphilis and HIV have remained a big threat to safe blood transfusion in Nigeria and Sub-Saharan Africa at large. Strict adherence to selection criteria and algorithm of donor screening are recommended.

Transfusion transmissible infections among blood donors from a sub-Himalayan rural tertiary care centre in Darjeeling, India

Background

In modern health services, blood transfusion is an essentially life-saving manoeuvre. With this situation healthy donor compilation is the cornerstone of transfusion medicine. Henceforth, a provision for strict criterion in recruitment and deferral of blood donors, particularly emphasizing transfusion transmissible infections (TTI), may improve safe transfusion practice.

Objectives

The present study was executed to assess the prevalence of TTIs within blood donors at a sub-Himalayan rural tertiary care institution in Darjeeling, India; which can ultimately aid in determination of the population subset to be targeted for enhancing donor pool.

Methods

The present study was a three-year (2010–2012) retrospective study. Data was accumulated and analysed from blood bank records, pertaining to all donors who were screened for various TTIs using respective immunological methods. Then the tabulated seropositive donors were correlated with relevant epidemiological profiles.

Results

Total 28,364 blood donors were examined, comprising of 25,517 (89.96%) males and 20,985 (73.98%) voluntary donors. Cumulative seroprevalence of HIV, HBV, HCV and syphilis were 0.42%, 1.24%, 0.62% and 0.65% respectively; with solitary malaria-infected donor. The overall seroreactivity in present study significantly diminished through successive years.

Conclusions

Deployment of implicit inclusion-exclusion criteria is high on demand for reducing the prevalence of TTIs, to increase the donor subpopulation strength and ultimately to institute a safe transfusion protocol.

A study of the noncompliance of blood banks on safety and quality parameters in blood donation camps in Bengaluru

Aims:

The compliance of safety and quality parameters laid out by national and international guidelines in outdoor blood donation camps has not been studied in India. Our study aimed at identifying, monitoring, analyzing, and developing preventive strategies for several key parameters associated with the quality and safety of outdoor voluntary blood donation camps (VBDC).

Settings:

The study covered a total of 424 VBDCs at various locations in Bengaluru, Karnataka (South India) from 2009 to 2013. Seven government hospitals based blood banks, three private hospitals based blood banks and two voluntary standalone blood banks participated in the VBDCs included in the study.

Materials and Methods:

At the onset, the quality and safety standards to be followed were discussed and agreed upon. During the study, noncompliance (NC) to the agreed upon standards were recorded and shared. Periodic trainings were also organized to help minimize NC.

Results:

One or more instances of NC in 73% of the VBDCs. Highest NC were observed associated with punctuality (34%), wearing gloves (16%), hemoglobin (Hb) estimation (11%) and donor screening and selection other than Hb check (8-9%).

Conclusion:

For all 16 parameters under study, significant NC was observed. As a whole private hospital based blood banks were more noncompliant. The high degree of NC to matters relating to quality and safety in VBDCs is high and warrants for urgent attention and further study. Our study also shows that regular monitoring and systematic and strategic intervention can decrease the rate of NC.
