2.5 Conclusion
Faith Alele and Bunmi Malau-Aduli
This chapter focused on critical appraisal and quality assurance of research evidence, as highlighted in the opening scenario. The thalidomide tragedy highlights the crucial importance of critically appraising peer-reviewed literature to evaluate the quality of evidence in research. In this case, the drug was prescribed to pregnant women based on anecdotal evidence and positive testimonials, rather than rigorous scientific testing. If the manufacturer had conducted proper scientific studies and if doctors had critically appraised the available evidence, they would have discovered the drug’s harmful effects and prevented the tragedy.
In research, it is crucial to collect and analyse enough high-quality data to draw valid and reliable conclusions. This means using appropriate methods to gather data, ensuring that the sample is representative, and minimizing bias in the data collection and analysis processes. Failing to gather sufficient evidence, or relying on inadequate or unreliable data, can result in flawed research that is not generalizable or replicable. Additionally, researchers must critically evaluate the evidence they have gathered and avoid jumping to conclusions or making premature claims. They should acknowledge the limitations of their findings and remain open to alternative explanations and interpretations of the data. They should also be transparent about their methods and share their data and findings with the scientific community to encourage scrutiny and replication.
Overall, it is essential to protect the well-being of individuals and society as a whole, and ensure that decisions are grounded in evidence-based research.
