Patient Change Calculator

Application Description
Statistically Reliable and Clinical Change calculator and display graph utility: this is a simple to use tool for physicians, students, academics, psychologists, physiotherapists and clinical auditors. It will help to evaluate outcomes for patients or performance (improvement/deterioration) for participants who complete standardized psychometric measures at baseline and end of treatment/course/trial or research. An essential and user-friendly tool to evaluate single or multiple subjects’ outcomes, when carrying out audit, clinical trials, research and/or wishing to assess the effectiveness of an intervention.
In the ‘Data’ tab, simply enter your subject’s score at baseline and end of treatment/program/intervention for as many subjects (minimum one subject) as required.
In the ‘RCI’ tab, apply the details of your psychometric measure and select whether your measure is negatively (i.e. bigger score, bigger problem/pathology) or positively (i.e. larger score = larger improvement/health) tuned. If you select ‘Show data points’, the graph will display a small triangle where the currently selected case is displayed (should you have more than one case). We have also added (in case you look at large number of cases) a 'Mean Scores' button to help you working out whether, on average, your service/data/participants have made an overall significant change. This point will be displayed by dotted lines crossing over on the graph when this function is switched on.
Simply click on the ‘Display results’ tab and this App will plot a ‘tramline’ display showing you whether the subject has obtained reliable (statistically significant) change by three different criteria. If the subject is outside of the dotted ‘tramline’ the change is reliable. The change is statistically significant depending on which criterion you choose (distance from the mean of a clinical or non-clinical population, or the average of the two, based on Jacobson & Truax, 1991 scientific paper). Below the graph you also have the cut-off scores for the three different criteria, Standard Error of Measurement and of the Difference, as well as the Reliable Change Index (Anything > 1.96 is significant at the 95% confidence level).
View on your device or copy/email the graph to copy and paste in presentation, documents, research papers and audit.
