Assignment: Analytic Study Design & Methods (Worksheet)
Primary Research Question
Did attendance at a NexGen promotional event by residents of the Portage County campus of Happy Valley, Inc. lead to an increased risk of acute HBV infection within the six months that followed?
Primary Hypothesis Set
Null hypothesis (H0): There is no difference in the six-month incidence rates of acute HBV infection between residents of the Portage County campus who did and did not attend the NexGen event.
Alternative hypothesis (H1): There is a difference in the six-month incidence rates of acute HBV infection between residents of the Portage County campus who did and did not attend the NexGen event.
Primary Objective
The objective was to find out whether there is a relationship between the attendance at the promotional event by NexGen and successive acute HBV development in Portage County Campus residents.
Study Population
The study population comprised the people who resided at the Portage County campus of Happy Valley and excluded those who lived at the Summit County neighbor campus of Happy Valley.
Primary Exposure Variable
Exposure to NexGen’s SugarChack glucometer is the primary variable. The leaders wanted to prove that the difference in outcomes between Summit County neighbor campus and Portage County campus results from exposure and not negligence (Burgess & Labrecque, 2018).
Primary Disease Variable
The primary disease variable studied is hepatitis B virus (HBV) and the survival rates due to the hepatitis B virus (HBV). The organization has been accused of negligence. Data has shown that people in the Portage County campus had a lower five-year survival rate and increased mortality compared to the Summit County neighbor campus. The organization was linking the adverse outcomes to an outbreak of HBV in the area.
Study Timeline
The events following the study include a promotional event by NexGen of a new glucometer six months earlier and publishing an article accusing Happy Valley, Inc. of negligence in one of its two campuses in the county. The study was in response to these accusations. The analytical data for the analysis is collected from administrative records of 252 people who reside at the Portage County campus of Happy Valley for demographic information. Then, the analyst will extract medical records of those people who were diagnosed with diabetes in the past. Besides, information concerning those who attended the NexGen event in the last six months will be included.
In the present, the analyst will gather follow-up information concerning processes, equipment, and supplies used among the residents who prescribed daily sugar monitoring in the last six months by interviewing caretakers and residents extensively. Moreover, in the present, the staff will perform a serologic test to determine the residents in the Portage County campus of Happy Valley are infected with hepatitis B virus (HBV).
Study/Comparison Group
Since the study applies a cross-sectional study design, there were no comparison groups. The study investigates all 252 residents on three factors, whether they attended the promotional event, developed acute HBV, and had a prescription of daily glucose monitoring.
Study Design
Study Options
The study should utilize a restriction study design, restricting the participants who will participate in the study. It restricts the participants by including the people diagnosed with diabetes, attended the NexGen event, and prescribed the daily glucose monitoring.
