Chosen clinical issue of interest
I chose hypertension as the clinical issue of interest. This is among the most prevalent medical issues in the contemporary world.
Despite the fact that hypertension has been a challenge in the healthcare sector, it is treatable, and hence its prevalence can be eradicated.
In the US, hypertension is known to be among the leading causes of heart diseases and even death risk.
Any person can get hypertension regardless of their age or gender. In America, hypertension is most prevalent amongst African Americans.

How I developed the PICO(T) Question
As explained by Grove et al (2015), I developed an PICO(T) evidence-based practice research question using participants/population, interventions utilized during the practice, comparisons of the intervention and outcome needed for practice within two months.
The PICO(T) question that guides this study is “In the adult population in the United States, how does the DASH diet compared to a non-restricted diet affect hypertension within two months?”
In the project, the population is the adults in the US, the Intervention is by DASH diet, Comparison is from a non-limited diet, and the outcome is the range of blood pressure.

Journal of the American Association of Nurse Practitioners, 26(9), 498-503. | Level 11 | The study followed a quasi-experimental time-series design for about two months. REAP and PHI survey scores were taken before and after the commencement of DASH diet intervention. | The REAP and PHI survey scores enhanced the accuracy of the study outcomes. They allowed for evaluation of the reliability in the research (Grove et al (2015). |

Preventive Medicine Reports, 4, 525-531. | Level 11 | The quantitative research followed a cross-sectional, descriptive approach. The collected data scored the sample on nine nutrients that consist of the DASH diet. | One notable strength of the study was the large sample size of 5848 people. This increases the representativeness of the overall study. |

Nutrition, Metabolism, and Cardiovascular Diseases : NMCD, 24(12), 1253-1261. | Level 1 | The sample population was selected following the systematic approach. A meta-analysis of all 17 randomized controlled trials was used to collect data. | The meta-analysis and systematic review of the study was one notable strength in the study. This is because it reduces occurrence of bias when evaluating the effectiveness of the treatment in the study. |
