Understanding urgent blood-donor mobilisability: a cross-sectional online survey of digitally reachable adults in Ghana
- 1School of Electronics and Computer Science, University of Southampton, Southampton, UK
Abstract
ObjectivesTo identify factors associated with anticipated engagement in urgent blood-donor mobilisation among digitally reachable adults in Ghana.
BackgroundDigital tools may facilitate contact with potential blood donors during emergencies and blood shortages, but digital reachability does not ensure engagement with urgent requests.
MethodsWe conducted a cross-sectional online survey across Ghanas 16 regions (September 2025-January 2026), recruiting participants via Facebook advertising and snowball sampling. Factors associated with urgent blood-donor mobilisability were assessed under four criteria: future-donation willingness; willingness to install a trusted donation app; willingness to respond to a trusted urgent-request; and practical flexibility to leave current activities. Descriptive analyses and multivariable logistic regression examined prevalence and associated factors.
ResultsOf 1,067 respondents, 577 (54.1%) met all four criteria, compared with 91.8% reporting high future-donation willingness. Trusted-app installation willingness (83.2%) and trusted-request response willingness (82.7%) exceeded practical flexibility (66.6%). High mobilisability was associated with formal health-system trust (AOR 3.95, 95% CI 2.08-7.50), digital-response readiness (AOR 2.26, 1.66-3.08), donation knowledge (AOR 1.42, 1.03-1.97) and previous donation (AOR 1.47, 1.08-2.01). Women (AOR 0.60, 0.43-0.83), those with work-schedule barriers (AOR 0.43, 0.29-0.66) and those reporting >30-minute night-time travel to the nearest healthcare facility (AOR 0.66, 0.45-0.96) had lower adjusted odds.
ConclusionsDigital reachability and stated donation willingness may overestimate the population pool available for emergency donation. Digital blood-donor solutions should consider verifiable health-system requests, account for digital-response readiness and current availability, and connect willing individuals with accessible collection options and transport support where needed.
