Youquality improvement team is located at a metropolitan hospital that serves a large population. The quality improvement team is conducting a study pertaining to readmissions, smoking and number of drugs administered to admitted patients with congestive heart failure (CHF). The team is interested in reducing the number of readmissions among patients discharged with a principal diagnosis of CHF. The team believes that the high admission rate is due to the difficulty that these patients have in controlling the number of drugs that they typically take. The team believes that by improving patient/family education regarding drug administration, the readmission rate could be reduced. Thus, they have developed the screen “CHF patients taking three or more drugs” to identify these patients before discharge. To evaluate the effectiveness of the measure, the team conducts a study on all CHF…arrow_forward

- Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and/or income affect the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affect the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…arrow_forwardRead through this scenario and look at the data that was collected.
