Critical appraisal of knowledge, attitude and practice studies for blood donation in India

Abstract

AbstractBackground and ObjectivesA critical appraisal of the literature helps to assess the strength and weakness of the research and suggests ways to improve future research. Our aim was to critically appraise the knowledge, attitude, and practice (KAP) studies conducted in India for blood donation.Materials and MethodsOf 70 articles identified in our search on PubMed, Scopus and Google Scholar, 32 were assessed for quality using an appraisal tool for cross‐sectional studies (AXIS) and questionnaire items.ResultsQuality assessment revealed that only 6 of 32 studies had acceptable reporting (≥80% score on the AXIS tool). The most frequently identified shortcomings were failure to address the non‐responders, lack of justification for sample size, assessment of outcome variables and demographic results for the survey. Our evaluation of questionnaires revealed that knowledge for need for blood donation, its benefits and site/place for blood donation were assessed by very few studies. With this, issues such as parental/family consent, religious beliefs, and indifference to blood donation process were amongst the common reasons for non‐donation. Many studies also failed to ask questions related to procedural information/instructions, which are necessary for promoting voluntary blood donations.ConclusionMost published KAP studies for blood donation in India were not appropriately described, especially the methodology and result section. These deficiencies could have led to suboptimal interpretation of the prevalent issues. Use of an open‐ended and validated KAP questionnaire with a problem‐based approach and inclusion of participants from various socio‐cultural backgrounds is required for good quality of evidence.
