Assignment task:
Respond to at least one peer with an analysis of the proposed data collection method and identify any limitations not addressed. (200 words).
PICOT question: In adult population with hypertension, does a low-sodium diet, compared to a regular diet, reduce blood pressure over six months?
For my research I chose the Secondary Quantitative data collection method as a method of data collection. I will review published reports posted by research institutions.
Setting
The setting for this research will primarily involve Academic and Research Databases such as PubMed, CINAHL, and JSTOR. These databases provide access to a wide range of peer-reviewed articles and medical studies, ensuring high-quality sources These databases will be used to gather secondary quantitative data by reviewing existing research and reports published by reputable research institutions. Accessing these databases, will allow to can obtain comprehensive, reliable, and relevant data that will support the investigation of the relationship between a low-sodium diet and blood pressure reduction in adults with hypertension over a six-month period.
Challenges and Limitations
Using secondary quantitative data collection for this research presents several challenges and limitations that could impact the accuracy of the findings. One key limitation is the potential misalignment between the available data and the specifics of the PICOT question. Additionally, inconsistencies in data collection methods-such as differences in blood pressure monitoring and sodium intake measurement-can introduce variability and make comparisons difficult. Sampling bias is another concern; if the studies in the secondary data do not fully represent the target population (adults with hypertension in outpatient settings), the findings may not be generalizable. Missing or incomplete data in secondary sources can also undermine the reliability of results. Finally, since secondary data is derived from pre-existing studies, there is no control over variables, which could introduce confounding factors affecting the outcomes.
