Randomized Control Trial

This follow-up study would be a prospective randomized control trial much like the original. Because the original Petrie et al. study had some problems with how small their sample size was and with the size of the pool of participants, a follow-up study should use a larger number of and broader range of participants. At least 150 participants should be enrolled in the study to ensure that the data is more workable than in the original study. Although it might create a better pool of patients to operate the study out of multiple hospitals, this would produce more variables and make it very difficult to analyze the data. Perhaps a next step would be to expand the study to see how different areas of the country respond differently to the intervention. …show more content…
used in their research. The patients should also fill out a brief survey about the exercise habits so that a personalized exercise plan can be created for them. Then the patients would be randomly assigned to one of the experimental conditions or control group. Patients in the control group would receive standard care, with no psychological or physical intervention. Patients in the first experimental group would receive the same intervention as the patients in the experimental group in the Petrie et al. study. Patients in the other experimental group would receive three 30-minute intervention sessions and three 30-minute exercise sessions. In the intervention sessions, the same structure from the 2002 study should be followed. Patients should receive counseling on the pathophysiology, causes of their disease, how to manage it, lifestyle change plans, symptoms of their disease, and concerns about returning home. Then the patients should participate in a structured exercise routine. The exercise should be as rigorous as is safe for each patient. A medical doctor should probably be the one to determine this and to supervise the exercising in case of emergency or question of ability to perform a certain act. A physical therapist and a cardiac rehabilitation therapist should be consulted as well in order to …show more content…
study should also be utilized in the follow-up study. Two-way analysis of variance and chi square tests should be used to determine between group differences. Two-way analysis of variance should be used to calculate the differences between groups in terms of their IPQ ratings before and after treatment and the differences in the hospital ratings. Analysis of covariance should again be used to compute the differences in the treatment group’s original IPQ scores and their IPQ scores at discharge. The Cox regression model should again be used to establish any demographic or medical variables in the delay in returning to work. The statistics used should resemble the ones used by Petrie and his colleagues because the follow-up study being proposed has very similar outcomes measures. Using the same measures of statistics means the same sorts of variables are being evaluated and the studies could eventually be
