9. 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?
Answer: D
The researcher is using a meta-analysis.
The researcher is compiling and reviewing findings from 100 related studies to assess the overall impact of smartphones on clinical outcomes for cardiac patients. This method is characteristic of a meta-analysis, which synthesizes data from multiple studies to draw broader conclusions.
A) Cohort study
A cohort study involves following a group of individuals over time to observe outcomes related to specific exposures or interventions. While it is a valid research method, it does not involve synthesizing results from multiple existing studies, which is the focus of the researcher.
B) Case study
A case study focuses on a detailed examination of a single patient or a small group of patients, often to explore unique conditions or responses. This approach does not encompass the large-scale synthesis of data from numerous studies as seen in the scenario described.
C) Clinical trial
A clinical trial is an experimental study that tests the effects of an intervention on participants, often involving randomization and control groups. The researcher in this instance is not conducting a trial but rather analyzing existing data from multiple studies, thus making this option incorrect.
D) Meta-analysis
A meta-analysis is a research method that systematically reviews and combines results from various studies to establish patterns or overall effects. The researcher’s task of examining and documenting findings from 100 related studies clearly aligns with this method, making it the correct choice.
Conclusion
The meta-analysis is the appropriate method utilized by the researcher, as it allows for the aggregation of data and insights from multiple studies to evaluate the impact of smartphones on cardiac patients. Other options, such as cohort studies, case studies, and clinical trials, do not fit the context of synthesizing existing research findings as described in the question. Thus, the choice of meta-analysis is definitive and clearly supported by the research context.
