Model for Improvement: How will we know that a change is an improvement? Show
Measurement is a critical part of testing and implementing changes; measures tell a team whether the changes they are making actually lead to improvement. Measurement for improvement should not be confused with measurement for research. This difference is outlined in the table below.
See also: Tips for Effective Measures. Three Types of MeasuresUse a balanced set of measures for all improvement efforts: outcomes measures, process measures, and balancing measures. Outcome Measures How does the system impact the values of patients, their health and wellbeing? What are impacts on other stakeholders such as payers, employees, or the community?
Process Measures
Balancing Measures (looking at a system from different directions/dimensions)
Sample MeasuresSee the Measures section for sample measures. Using Sampling: An ExampleHere is how one team used sampling in measuring the time for transfer from Emergency Department (ED) to inpatient bed. Rapid movement from the Emergency Department (ED) after a decision to admit the patient is critical flow for entry to the entire system for emergent patient care. It represents the ability of patients with various illnesses to get into the system through the most common admission route. Sampling approach: The measurement will consist of 6 weekly data collections of 25 patients each. The patients can be sampled in several ways:
or
or The time is measured from the decision to admit to the physical appearance of the patient into the inpatient room. The destination cannot be a "holding area" but must be a "real inpatient bed." The sample collection should be done in real time, so a data collection process needs to be worked out by members of the team to achieve this goal. The collections must be done weekly and summarized as the percentage of patients in the sample that achieved the goal for that week. Six weeks of data needs to be collected and six data points placed on a run chart. Plotting Data Over TimePlotting data over time using a run chart is a simple and effective way to determine whether the changes you are making are leading to improvement. Annotate the run chart to show the changes you made. You can use the Improvement Tracker to automatically plot your data over time. Example
1: Example 2: What is the ability of a test to measure what it was designed to measure?Reliability is an examination of how consistent and stable the results of an assessment are. Validity refers to how well a test actually measures what it was created to measure.
What is a measure of a test's ability to measure what it is designed to measure quizlet?Validity refers to a test's ability to access what it was designed to assess.
Which of the following types of tests is designed to measure an individual's knowledge of a subject?Achievement tests are designed to measure the knowledge and skills students learned in school or to determine the academic progress they have made over a period of time.
What type of test measures what a person has learned?An achievement test measures how an individual has learned over time and what the individual has learned by analyzing his present performance. It also measures how a person understands and masters a particular knowledge area at the present time.
