Observational studies: practical tips for avoiding common statistical pitfalls

This Personal View is intended for early-career researchers who are not yet experts in statistics. The Personal View focuses on common but usually avoidable flaws in the context of observational studies. I point out how study design, data collection, and statistical methods impact statistical results and research conclusions. With particular attention to study planning, sample selection, biases, lack of transparency and results misinterpretations.

Gamification in pharmacy education: a systematic quantitative literature review

OBJECTIVES

Gamification involves applying game attributes to non-game contexts and its educational use is increasing. It is essential to review the outcomes and the efficacy of gamification to identify evidence to support its use in pharmacy education.

THIS ARTICLE

systematically and quantitatively reviews and evaluates the alignment of learning outcomes and the quality of peer-reviewed literature reporting gamification in pharmacy education.

KEY FINDINGS

A literature search was undertaken in February 2022 using CINAHL Complete, MEDLINE, Science Direct, Scopus and ERIC databases, via keywords (game* OR gaming OR gamif*) AND pharmac* AND education. Google Scholar was searched using 'gamification of pharmacy education' and 'serious games in pharmacy education'. Data extracted included type of gamified intervention, mode of delivery, game fidelity, intended learning outcomes and outcomes reported. Quality assessments aligned with key aspects of the SQUIRE-EDU Reporting Guidelines. Of 759 abstracts and 95 full-text papers assessed, 66 articles met the inclusion criteria. They described gamification from 12 countries in the education of 8272 pharmacy and health professional students. Gamified interventions ranged from board games to immersive simulations, with escape rooms most frequently reported. Reporting quality was inconsistent, with observed misalignment between intended learning outcomes and outcomes reported, an apparent overreliance on student perceptions as primary data and a lack of reference to reporting guidelines.

SUMMARY

Gamification is included in the curricula of many pharmacy degrees, across multiple subject areas. This review identified evidence gaps and reinforces the need for improved quality of gamification research, critical alignment of learning outcomes with evaluation, and use of reporting guidelines.
