Summary

Predicting blood donor arrival using statistical modeling significantly reduces prediction intervals by 43%. This helps blood banks better plan sessions and minimize donor wait times for improved experiences.

Area of Science:

  • Biomedical Informatics
  • Public Health
  • Operations Research

Background:

  • Short waiting times enhance donor experience and encourage repeat donations.
  • Blood banks face challenges with variable donor arrival rates despite using fixed appointments.
  • Predictive methods are needed to manage donor flow and reduce wait times.

Purpose of the Study:

  • To develop a statistical model for predicting blood donor arrival.
  • To identify key factors influencing donor attendance.
  • To improve the efficiency of blood donation sessions.

Main Methods:

  • Collected data on 179,121 appointments over 971 days.
  • Utilized logistic regression to model blood donor arrival prediction.
  • Analyzed 18 candidate explanatory variables.

Main Results:

  • Key predictors include time to appointment, contact medium, donor age, donation history, and past attendance/no-show rates.
  • The model reduced prediction intervals by 43% compared to using average arrival rates.
  • Identified significant variables influencing donor no-shows and attendance.

Conclusions:

  • Statistical modeling offers valuable insights into blood donor arrival patterns.
  • Predictive models enable better planning and resource allocation for blood donation sessions.
  • Improved planning can lead to reduced donor waiting times and enhanced satisfaction.
