- Your hospital Vice-President for Population Health asks you to research and evaluate the most commonly used planning models for conducting the community health needs assessments (CHNA) that the IRS requires of not-for-profit hospitals. In your research you find that the U.S. Centers for Disease Control and Prevention (CDC) recommends that CHNA (and the community health assessments – CHAs - that health departments conduct) follow eight steps in an assessment. Review the an overview of commonly used planning models described on this CDC website. Also review four examples of common models below. ACHI AHA Community Health Improvement Catholic Health Association NACCHO ASTHO- SHIP Finally, enter a bullet or phrase in each of the cells in this (the attached template) that describes how each of the planning modules addresses the 8 steps in a CHNA/CHA process. This evaluation template will form the basis of your report to your Vice-President.Please Help with this question: In 1985, a researcher conducted a study of mortality among a cohort of shipyard workers who were employed at Pearl Harbor naval yard during World War II.

- 8. True or False? Relative risk is an ideal form of measurement for a retrospective cohort study design because it allows researchers to recruit both individuals with the outcome of interest and individuals without the outcome of interest, then match individuals from each of the respective groups to individuals of the other group to determine if a specific exposure caused the outcome of interest.To test the efficacy of vitamin C in preventing colds, army recruits were randomly assigned to one of two groups: 500 mg of vitamin C daily and a placebo (sugar pill) daily. Both groups were then followed for a year to determine the number and severity of subsequent colds. What type of study design is it? Ecologic study Quasi experimental study Case-control study Cohort study Randomized controlled trialTrue or False? An active-control trial is the best option for researchers hoping to test a newly devised therapy for a life-threatening illness among individuals with the illness, when a previously devised treatment is available for the illness.
