An analysis of Pre- and Post- Blood Donor’s behaviour through Regression Models

Abstract

Donor retention poses a significant problem to blood collection agencies around the world. Blood requirement are increased in the recent year. Though there is an increase for blood requirement, the blood donation percentage in Odisha is only 5%. This research is an augmented theory of planned behaviour (TPB) approach has demonstrated that attitude, subjective norm, self-efficacy, moral norm, anticipated regret, donation apprehension from prior to post blood donations, and self-identity as a blood donor predicts experienced donors' intentions and that intentions, self-efficiency, moral norm, and anticipated regret may impact upon people's actual blood donation behaviour. This paper describes a framework within which standard time-to-outcome methods can be used to analyses blood donor behaviour. Survival curves and relative risk estimates derived from a proportional hazard’s analysis of a large administrative dataset are reported. In addition to assessing the effect of sex, age and other key donor demographic factors on the probability of a subsequent donation attempt, the analysis reveals that the relative risks are time-dependent. This research suggests that the likelihood of attempting a subsequent donation may also depend on the time since the index donation attempt.
