Professor and class
Researchers use instruments as a measurement device and they can be categorized as researcher-completed and subject completed depending on who administered or completed respectively. Based on the research question, researchers select what instrument they are going to use.
Some researcher-completed instruments are rating scales, interviews, flowcharts, checklists, time and-motion logs, observation forms, etc. Some of the subject-completed instruments are questionnaires, attitude scales, personality inventories, achievement tests, sociometric devices, etc.
In my proposed research project I am going to use a the Readmission Rate , based on a relation between the total number of patients discharged home with the diagnosis of Congestive Heart Failure and an inpatient admission for decompensating Cardiac Heart Failure within 30 days of the discharge .This number is going to be the numerator of the fraction. The denominator is going to be those all patients discharge from the hospital with the diagnosis of Cardiac Heart Failure and the number is going in the last three months. The denominator is going to be common for the two groups the experimental group and the control group.
All patients included in the investigation will be applied the LACE Index. The LACE Index is a tool to evaluate the Risk of readmission of a patient admitted in the hospital, and it is used as a predictor of readmissions. It consists of 4 parameters as described below:
Length of stay It will score 0,1,2,3,4,5,7 according to the days of stay: less than 1, 1, 2,3,4-6, 7-13, >=14 respectively.
Acuity if it was emergent admission it will score 3.
Comorbidities will be assessed by Charlson score .No comorbidities will score 0, 1 Comorbidity scores 1, 2 Comorbidities scores 2, 3 comorbidities scores 3, and more than 4 scores 5.
Emergency department visits on the last six months No visits 0, 1 visit scores 1, 2 visits scores 2, 3 visits scores 3, and 4 or more scores 4.According to the classification of the measurement tools this level of measurement is considered as ordinal.
The interpretation of the LACE Index is that if the Index scores is 0-3 there is a low risk of readmissions, if it is between 4 and 9 the risk is moderate , and if it is more than 9 the risk is high.
