A researcher wants to determine whether smartphones can be used to positively impact clinical outcomes of cardiac patients… proceeds to research and document another 100 related studies. Which research method is this researcher using?

Rationale

Meta-analysis

A meta-analysis is a research method that systematically reviews and aggregates data from multiple studies to draw comprehensive conclusions about a particular topic. In this case, the researcher is synthesizing information from 100 related studies to evaluate the impact of smartphones on clinical outcomes in cardiac patients.

A (Cohort study) YOUR ANSWER

A cohort study is an observational research method that follows a group of individuals over time to assess the effects of certain exposures or treatments. However, this researcher is not following a specific cohort but rather collecting and analyzing existing studies, making this option incorrect.

B (Case study) YOUR ANSWER

A case study involves an in-depth examination of a single subject or a small group, often focusing on unique or rare cases. The researcher in this scenario is not examining individual cases but rather compiling results from numerous studies, so this option does not apply.

C (Clinical trial) YOUR ANSWER

A clinical trial is a controlled experiment that tests the effects of an intervention on participants in a systematic way. The researcher is not conducting an original trial but instead reviewing existing research, which makes this option inappropriate for the situation described.

D (Meta-analysis) CORRECT

This option correctly identifies the research method used, as the researcher is synthesizing findings from 100 studies to evaluate the broader impact of smartphones on clinical outcomes, thereby generating new insights from existing data.

Conclusion

The researcher is employing a meta-analysis, a method that compiles and analyzes data from multiple studies to evaluate a specific research question. This approach is essential for understanding complex clinical questions, as it allows for a more comprehensive view of the existing literature and can highlight trends and outcomes that might not be apparent from individual studies alone.
