Quality assessment tool for Outdoor Blood Donation Drives: an Indian perspective

Assessing the quality of blood donation drives is imperative for maintaining blood safety. Currently, there are no validated tools for evaluating the Outdoor Blood Donation Drive (OBDD). This study intends to develop and validate a quality assessment tool for OBDD in India.

This cross-sectional study was conducted over 12 months at a tertiary-care blood centre in India. Three phases of the study were tool development and validation, OBDD quality assessment, and mini-tool development. Internal consistency was assessed using Cronbach's alpha. Spearman's correlation matrix assessed variable correlations' direction and strength. Psychometric tests, including Bartlett's sphericity test and Kaiser-Meyer-Olkin score, were used. For factor analysis, Principal Axis Factoring with Oblimin rotation was utilized.

A 30-item questionnaire was developed to assess OBDD quality. The tool had high content validity (mean I-CVI: 0.93) and reliability (Cronbach's alpha: 0.89). Out of 100 ODBB assessed, around 67 % scored Grade B and 17 % scored Grade C. Scores were low for aspects such as display of IEC materials, restroom facility, grade of registration, grade of collection, and pre-drive awareness. Following an iterative process based on the KMO Measure of Sampling Adequacy (MSA), communality values, and factor loadings, a 15-item tool was developed. The Cronbach's alpha of the tool was 0.80, denoting good internal consistency.

The developed comprehensive and mini quality assessment tool, comprising 30 and 15 parameters, was found valid and reliable. This can be adapted as per the required customisation across blood centres globally.
