RESUMO

In rural settings worldwide, many people live in effective blood deserts without access to any blood transfusion. The traditional system of blood banking is logistically complex and expensive for many resource-restricted settings and demands innovative and multidisciplinary solutions. 17 international experts in medicine, industry, and policy participated in an exploratory process with a 2-day hybrid seminar centred on three promising innovative strategies for blood transfusions in blood deserts: civilian walking blood banks, intraoperative autotransfusion, and drone-based blood delivery. Participant working groups conducted literature reviews and interviews to develop three white papers focused on the current state and knowledge gaps of each innovation. Seminar discussion focused on defining blood deserts and developing innovation-specific implementation agendas with key research and policy priorities for future work. Moving forward, advocates should prioritise the identification of blood deserts and address the context-specific challenges for these innovations to alleviate the ongoing crisis in blood deserts.

RESUMO

BACKGROUND: The supply of blood in many low- and middle-income nations in Sub-Saharan Africa (SSA) does not meet the patient care needs. Lack and delay of blood transfusion cause harm to patients and slow the rate of progress in other parts of the health system. Recognizing the power of implementation science, the BLOODSAFE Program was initiated which supports three SSA research study teams and one data coordinating center (DCC) with the goal to improve access to safe blood transfusion in SSA. STUDY DESIGN AND METHODS: The study team in Ghana is focusing on studying and decreasing iron deficiency in blood donors and evaluating social engagement of blood donors through different approaches. The study team in Kenya is building a "vein to vein" workflow model to elucidate and devise strategies to overcome barriers to blood donation and improve infrastructural components of blood product production and use. The Malawi team is studying the infectious disease ramifications of blood donation as well as blood donor retention strategies aimed at blood donors who commence their donation career in secondary schools. RESULTS AND DISCUSSION: Together the project teams and the DCC work as a consortium to support each other through a shared study protocol that will study donor motivations, outcomes, and adverse events across all three countries. The BLOODSAFE Program has the potential to lead to generalizable improvement approaches for increasing access to safe blood in SSA as well as mentoring and building the research capacity and careers of many investigators.

RESUMO

BACKGROUND: Antimicrobial resistance (AMR) is a global health challenge, particularly in low- and middle-income countries where antibiotics are widely available to consumers, leading to their misuse. However, AMR educational interventions for engaging parents of schoolchildren are mainly lacking in Sub-Saharan Africa. This study aimed to assess the potential of AMR animation and schoolchildren in influencing parents' AMR knowledge, attitudes, and beliefs. METHODS: Parents of schoolchildren aged 11-15 years in Tema, a city in Ghana, watched and discussed an AMR animation designed with ideas from the schoolchildren's top stories and picture drawings. The children from two schools were first engaged with AMR lessons, with one school using storytelling, the other school using picture drawing, and none serving as a control. The children were then asked to discuss the lessons with their parents. Baseline surveys of parents of randomly selected children were conducted to assess AMR knowledge, attitudes and beliefs before engaging the students and parents, and immediately after the parents participated in viewing and discussing the animation. McNemar and t-tests were used to assess changes in AMR knowledge, attitudes and beliefs. RESULTS: Parents who participated in the animation event, and whose schoolchildren were in the storytelling intervention school had significantly improved knowledge regarding the statement "Antibiotics will cure any infection" (p = 0.021, χ2 = 0.711; 88% vs 50%) between baseline and endline. However, these parents also had statistically significant decreased scores regarding the statement "Antibiotics do not kill our good bacteria" (p = 0.021, χ2 = 1.042; 71.4% vs 40%) between baseline and endline. There was no significant effect on any statement among parents whose children were in the picture drawing school. However, t-test results combining the statements as composite scores showed statistically significant difference in only the attitude construct among parents whose children participated in storytelling intervention (p = 0.043) or picture drawing intervention (p = 0.019). There were no statistically significant changes in knowledge and beliefs constructs. CONCLUSIONS: This study shows that interventions involving schoolchildren with parents engagements and AMR animation could influence parents' AMR attitudes. The intervention could also positively or negatively impact parents' AMR knowledge. Modifications of the interventions may be needed for tackling AMR.

RESUMO

As several low- and middle-income countries roll out their COVID-19 vaccination programmes, COVID-19 vaccines hesitancy could threaten the success of such programmes. But pharmacists can play a leading role in addressing COVID-19 vaccine hesitancy by using a critical mobile phone-based technology. This technology, known as caller tunes or ringback tones, is flourishing in low- and middle-income countries such as those in Africa and Asia where it is used to promote popular songs and religious messages. With this technology, callers to mobile phones hear a message or a song instead of the typical ringing sound. There is a need for pharmacists associations to collaborate with the creative arts industry and telecommunication companies to have caller tunes on COVID-19 vaccines. As pharmacists and others download COVID-19 vaccine caller tunes onto their mobile phones, their callers will hear COVID-19 vaccines messages or songs. This could help combat disinformation and hesitancy, and promote widespread vaccination as availability increases.

RESUMO

The low recruitment and retention of blood donors in sub-Saharan Africa is a grave concern for blood transfusion services in the region. This problem is exacerbated by factors such as a high prevalence of transfusion-transmissible infections and anaemia, over-reliance on family replacement donors, resource constraints, and poor communication with the public. To improve blood safety and availability, innovative intervention strategies must be developed and implemented. The primary objective of this Series paper is to discuss the available evidence in the region and to provide recommendations on how to improve safe blood supply in sub-Saharan Africa. These recommendations include a call for renewed attention to donor recruitment in blood transfusion centres, a consistent and structured educational intervention, the development and adherence to national policies on blood donor selection with focus on voluntary donations, and comprehensive screening of donations for transfusion-transmissible infections.

RESUMO

Background: In several African and Asian countries, callers to mobile phones sometimes hear a song or message in place of the typical ringing sound. This application, called caller tunes, may offer a unique opportunity to promote medication adherence that is yet to be explored. Objectives: Assess the application of the technology acceptance model to a potential caller tunes approach designed to enhance medication adherence, with a specific focus on the interrelationships of perceived ease of use, perceived usefulness, cost, and intention. Methods: Data from a cross-sectional sample of 996 adult mobile phone users in Ghana, approximately half of whom were current caller tunes users, was examined using exploratory factor analysis for scale evaluation and structural equation modeling to assess associations among perceived ease of use, perceived usefulness, and cost on intention to use mobile phone caller tunes to promote medication adherence. Results: Consistent with the technology acceptance model, intention to use the caller tunes as a means of enhancing medication adherence was higher among those who viewed the application positively in terms of ease of use and usefulness. Among those who were already caller tunes users, availability as a free download was also associated with more positive intentions. Conclusion: The present study provides preliminary evidence in support of caller tunes as a novel strategy to promote medication adherence. Future studies interested in using this approach would be advised to consider factors such as participants' current use of caller tunes, age, availability as a free download, and perceptions of ease of use and perceived usefulness of the approach as potential moderators of study outcomes.

RESUMO

OBJECTIVE: This study seeks to identify factors that are predictive of intention to return to donate blood among first-time blood donors. METHODS: A cross-sectional survey of 505 first-time blood donors, selected from blood donation sessions across three regions in Ghana. Data were obtained on their intention to donate blood in the next four months, factors that would influence this decision. Logistic regression models were used to test factors that were predictive of intention to return. RESULTS: First-time donors were young with 87·4% below 35 years of age, male (72·5%), single (73·3%), Christian (93·7%), employed (58·8%), with at least a basic education (98%). Factors that positively predicted intention to return included: motivational incentives (OR = 1·67, 95%CI: 1·01-2·78; P = 0·045); ease of access to the donation site (OR = 2·65, 95%CI: 1·48-4·73; P = 0·001); SMS and email reminders (OR = 2·84, 95%CI: 1·60-5·06; P < 0·001); and television, radio or newspaper advertisements (OR = 2·97, 95%CI: 1·66-5·31; P < 0·001). Factors that negatively predicted intention included preferential access to transfusions (i.e. 'blood credits') (OR = 0·43, 95%CI: 0·23-0·83; P = 0·012); getting to know test results (OR = 0·40, 95%CI: 0·20-0·80; P = 0·010); and not knowing and/or trusting what happens to the blood after donating (OR = 0·50, 95%CI: 0·28-0·88; P = 0·016). CONCLUSION: Motivational incentives, convenient access to donation sessions, reminders and mass media advertisements appear to positively influence intention to return to donate. Conversely not knowing what happens to the blood after donation negatively influenced intention to return. Interventions to promote repeat blood donation should consider the identified factors.

RESUMO

BACKGROUND: Detection of HIV-1 transmitted drug resistance (TDR) and subtype diversity (SD) are public health strategies to assess current HIV-1 regimen and ensure effective therapeutic outcomes of antiretroviral therapy (ART) among HIV-1 patients. Globally, limited data exist on TDR and SD among blood donors. In this study, drug resistance mutations (DRMs) and SD amongst HIV-1 sero-positive blood donors in Accra, Ghana were characterized. METHODS: Purposive sampling method was used to collect 81 HIV sero-positive blood samples from the Southern Area Blood Center and confirmed by INNO-LIA as HIV-1 and/or HIV-2. Viral RNA was only extracted from plasma samples confirmed as HIV-1 positive. Complementary DNA (cDNA) was synthesized using the RNA as a template and subsequently amplified by nested PCR with specific primers. The expected products were verified, purified and sequenced. Neighbour-joining tree with the Kimura's 2-parameter distances was generated with the RT sequences using Molecular Evolutionary Genetic Analysis version 6.0 (MEGA 6.0). RESULTS: Out of the 81 plasma samples, 60 (74%) were confirmed as HIV-1 sero-positive by INNO-LIA HIVI/II Score kit with no HIV-2 and dual HIV-1/2 infections. The remaining samples, 21 (26%) were confirmed as HIV sero-negative. Of the 60 confirmed positive samples, (32) 53% and (28) 47% were successfully amplified in the RT and PR genes respectively. Nucleotide sequencing of amplified samples revealed the presence of major drug resistance mutations in two (2) samples; E138A in one sample and another with K65R. HIV-1 Subtypes including subtypes A, B, CRF02_AG and CRF09_cpx were found. CONCLUSION: This study found major drug resistance mutations, E138A and K65R in the RT gene that confer high level resistance to most NNRTIs and NRTI respectively. CRF02_AG was most predominant, the recorded percentage of subtype B and the evolutionary relationship inferred by phylogenetic analysis may suggest possible subtype importation. However, a more prospective and detailed analysis is needed to establish this phenomenon. The data obtained would inform the selection of drugs for ART initiation to maximize therapeutic options in drug-naïve HIV-1 patients in Ghana.

RESUMO

BACKGROUND: Patient reporting of adverse drug reactions (ADRs) is low in low- and middle-income countries, in part because of poor awareness to report. With the increase in mobile subscription, mobile phones can be used as a platform to disseminate information on ADRs. The aim of this study was to qualitatively assess the potential of using mobile phone caller tunes (the message or sound the caller hears before the receiver answers the call) to encourage patient reporting of ADRs. METHODS: A total of 38 key informant interviews and 12 focus group discussions (57 participants in groups of 4-5) were conducted in Accra, Ghana. The transcripts were analysed using key constructs of the Technology Acceptance Model (TAM) including perceived usefulness, perceived ease of use, and behavioural intention to use caller tunes for patient reporting of ADRs. RESULTS: Respondents mentioned lack of knowledge on reporting ADRs, and their willingness to use mobile phone caller tunes to promote patient reporting of ADRs. Many respondents pointed out how ADRs usually led to discontinuity in medication use, usually without consultation with health professionals. Caller tunes were regarded an innovative, accessible and convenient platform to disseminate information on ADRs. Most respondents intended to use caller tunes with drug safety information to promote ADR reporting, particularly to help their friends and family members. Simplicity of the message, use of songs or messages in local languages and price of downloading the caller tunes were important considerations. CONCLUSION: There is a need for the creation and testing of caller tunes on ADRs in Ghana to promote patient or consumer reporting of ADRs. Further studies are needed to assess factors that could influence the creation and use of caller tunes to disseminate information on drug safety.

RESUMO

BACKGROUND: Voluntary blood donation rates are low in sub-Saharan Africa. Sociobehavioral factors such as a belief that donated blood would be used for performing rituals deter people from donating blood. There is a need for culturally appropriate communication interventions to encourage individuals to donate blood. Health care interventions that use mobile phones have increased in developing countries, although many of them focus on SMS text messaging (short message service, SMS). A unique feature of mobile phones that has so far not been used for aiding blood donation is caller tunes. Caller tunes replace the ringing sound heard by a caller to a mobile phone before the called party answers the call. In African countries such as Ghana, instead of the typical ringing sound, a caller may hear a message or song. Despite the popularity of such caller tunes, there is a lack of empirical studies on their potential use for promoting blood donation. OBJECTIVE: The aim of this study was to use the technology acceptance model to explore the influence of the factors-perceived ease of use, perceived usefulness, attitude, and free of cost-on intentions of blood or nonblood donors to download blood donation-themed caller tunes to promote blood donation, if available. METHODS: A total of 478 blood donors and 477 nonblood donors were purposively sampled for an interviewer-administered questionnaire survey at blood donation sites in Accra, Ghana. Data were analyzed using descriptive statistics, exploratory factor analysis, and confirmatory factory analysis or structural equation modeling, leading to hypothesis testing to examine factors that determine intention to use caller tunes for blood donation among blood or nonblood donors who use or do not use mobile phone caller tunes. RESULTS: Perceived usefulness had a significant effect on intention to use caller tunes among blood donors with caller tunes (beta=.293, P<.001), blood donors without caller tunes (beta=.165, P=.02, nonblood donors with caller tunes (beta=.278, P<.001), and nonblood donors without caller tunes (beta=.164, P=.01). Attitudes had significant effect on intention to use caller tunes among blood donors without caller tunes (beta=.351, P<.001), nonblood donors with caller tunes (beta=.384, P<.001), nonblood donors without caller tunes (beta=.539, P<.001) but not among blood donors with caller tunes (beta=.056, P=.44). The effect of free-of-cost caller tunes on the intention to use for blood donation was statistically significant (beta=.169, P<.001) only in the case of nonblood donors without caller tunes, whereas this path was statistically not significant in other models. CONCLUSIONS: Our results provide empirical evidence for designing caller tunes to promote blood donation in Ghana. The study found that making caller tunes free is particularly relevant for nonblood donors with no caller tunes.

RESUMO

Achieving an adequate blood supply in Sub-Saharan Africa (SSA) through donor mobilization and retention is crucial. Factors that motivate or deter blood donors vary according to beliefs and social norms. Understanding the factors that influence blood donation behaviour in SSA is vital to developing effective strategies to address blood donor motivation and retention. This review of 35 studies from 16 SSA countries collates available evidence concerning the perceptions, motivators and deterrents that influence blood donors in SSA. The review revealed a common understanding that blood and blood donation save lives. The main deterrent to blood donation was fear due to lack of knowledge and discouraging spiritual, religious and cultural perceptions of blood donation. The main motivators for blood donation were altruism, donating blood for family and incentives. The findings support the need for targeted, culturally sensitive education, recruitment and retention strategies to improve the blood supply in SSA.
