Turning Data into Useful Information Data Display Objectives This presentation will help you to do the following: § Evaluate the effectiveness of various display methods and choose between them depending on your data display goals and needs. Data Display | Slide 2 © Joint Commission Resources, Inc. § Understand when and how to use overview displays, such as a balanced scorecard, dashboard summary, and performance matrix.
Turning Data into Useful Information Data Display Ways to Display Data Having random numbers or comments isn’t helpful if you can’t interpret them. Displaying data can help you interpret what you need to know about performance. Data Display | Slide 3 © Joint Commission Resources, Inc. There are many ways to display data, from a basic comparison chart to graphs that allow for a more detailed analysis. The analysis of the data you want to do will help determine the appropriate display method.
Turning Data into Useful Information Data Display Box Plots What Are They? One of the most basic ways to display data is the box plot. Box plots are used to identify patterns and help you decide if you need a more detailed analysis. They are also useful to compare sets of data quickly and to summarize a detailed analysis when you need to present your results. Data Display | Slide 4 © Joint Commission Resources, Inc. However, if you need to investigate a problem or determine why or how something is occurring, this format does not provide that level of detail.
Turning Data into Useful Information Data Display Box Plots (continued) A box-plot is a five-number summary or a set of data: median, lower quartile, upper quartile, and some indication of more extreme upper and lower values. A box encloses the space between the first and third quartiles. The median is indicated by a line dividing the box. The highest and lowest values are shown as the ends of lines extending from the box. The sample box plot shows the expected lengths of stay for six hospitals. It shows the hospitals with the three lowest and highest expected lengths of stay.

Box plots are used to identify patterns, compare sets of data quickly, and summarize a detailed analysis when you need to present your results.
Turning Data into Useful Information Data Display Box Plots (continued) What are two situations you can think of where you might use, or have used, a box plot? What your colleagues said: “Monitoring medical record documentation completeness helps me make sure that we are using resources responsibly and managing care appropriately. ” “I watch wait times for outpatient procedures. I know my community values innovative and responsible use of resources, and spending too long on a procedure doesn’t meet their needs. ” Data Display | Slide 6 © Joint Commission Resources, Inc. “I like to eliminate as much unneeded or redundant tests conducted on patients as possible. ”
Turning Data into Useful Information Data Display Comparison Charts What Are They? A comparison chart is another easy tool to display data, but it is more sophisticated than a box plot. Comparison charts allow you to compare two or more groups of data. For example, you can compare your organization’s performance against other organizations. To use comparison charts effectively, consider these questions: § How does performance compare against the norm over time? § If there are performance outliers, do they indicate unusual success or a need for improvement? If so, what can be learned from these outliers? Data Display | Slide 7 © Joint Commission Resources, Inc. § Is a plan in place to investigate both positive and negative outliers?
Turning Data into Useful Information Data Display Comparison Charts (continued) Here you see the comparative data displayed as a comparison chart. You can use a comparison chart while benchmarking to compare your organization against others or a national aggregate.

Turning Data into Useful Information Data Display Terminology Analysis: The process of interpreting data and transforming it into information. Assess: To transform data into information by analyzing it. Assessment: The systematic collection and review of patient-specific data. Assessment of performance data examines performance over time and in comparison to other referents. Balanced Scorecard: A strategic management approach that helps align and sustain performance in financial matters, customer knowledge, internal business practices, and learning and growth. Benchmarking: Continuous measurement of a process, product, or service compared to those of the toughest competitor, to those considered industry leaders, or to similar activities in the organization to find and implement ways to improve it. This is one of the foundations of both total quality management and continuous quality improvement. Internal benchmarking occurs when similar processes within an organization are compared. Competitive benchmarking occurs when an organization’s processes are compared with best practices within the industry. Functional benchmarking refers to benchmarking a similar function or process, such as scheduling, in another industry. Best practices: Clinical, scientific, or professional practices that are recognized by a majority of professionals in a particular field. These practices are typically evidence based and consensus driven. Box plot: A five-number summary or a set of data. A box encloses the space between the first and third quartiles. The median is indicated by a line dividing the box. The highest and lowest values are shown as the ends of lines extending from the box. Checklist: A form for gathering data that records whether a specific action has been performed. Common cause variation: Variation in a process that is due to the process itself and is produced by interactions of variables of that process. Common cause variation is inherent in all process. It can be altered only by changing the process. Comparison chart: A graph that compares two or more separate groups of data. Control chart: A graphic display of data in the order that they occur with statistically determined upper and lower limits of expected common cause variation. It is used to identify special causes of variation, monitor a process for maintenance, and determine whether process changes have had the desired effect. Data Display | Slide 46 © Joint Commission Resources, Inc. Check sheet: A simple tool that shows how often an event or condition occurs, it is used to record data that answer objective statements requiring a simple yes/no response.
Turning Data into Useful Information Data Display Control limit: In statistics, an expected limit of common-cause variation, sometimes referred to as either an upper or lower limit. Variation beyond a control limit is evidence that special causes are affecting a process. Control limits are calculated from process data and are not to be confused with engineering specifications or tolerance limits. Control limits are typically plotted on a control chart. Criteria: Expected levels of achievement or specifications against which performance or quality may be compared Dashboard summary: A simplified organization report like an executive summary or an organization or initiative. It is based on the dashboard of a car that shows at a glance the areas that are doing well and which areas present problems. Data: Uninterrupted measurements, facts, or clinical observations collected during an assessment activity. Data may be numeric or quantitative. It can also be non-numeric or qualitative, reflecting the “lived experience” of the population of interest. Data integrity: In the context of data security, the protection of data from accidental or unauthorized intentional changes. Data collection: The act or process of capturing raw or primary data from a single source or a number of sources. Also called data gathering. Data collection plan: A carefully considered, documented plan that covers what, how, when, and where specifics of data collection. It is based on the goals stated and measures chosen. Data element: A discrete piece of data, such as a patient birth date or principal diagnosis. Data point: The representation of a value for a set of observations or measurements at a specific time interval. Data sources: The primary source document used for data collection. The developer may choose to standardize the data sources used for data collection across organizations, or may allow data to be collected from several sources at the participating organizations’ discretion. Double jeopardy: A deteriorating performance situation when expectations are raised and results deteriorate that often needs to be improved. Effectiveness: The degree to which the care is provided in the correct manner, given the current state of knowledge, to achieve the desired or projected outcome for the patient. Efficacy: The degree to which the care of the patient has been shown to accomplish the desired or projected outcome. Data Display | Slide 47 © Joint Commission Resources, Inc. Drill down: Questions that can help organizations assess where there is a problem with a process or area of service and effectively uses data to find solutions to the problem.
Turning Data into Useful Information Data Display Efficiency: The relationship between the outcomes and the resources used to deliver patient care. Failure, Mode, and Effects Analysis: A systematic way of examining a design prospectively for possible ways in which failure can occur. It assumes that no matter how knowledgeable or careful people are, errors will occur in some situations and may even be likely to occur. Feedback: Performance measurement systems regularly provide summary reports on data quality to the health care organization leadership to stimulate self-monitoring and improvement in data quality. Focus: The activity or area on which the measure centers attention. Histogram: A graphic display, using a bar graph, of the frequency distribution of a variable. Indicator: A measure used to determine, of time, an organization’s performance of functions, processes, and outcomes. Information: Knowledge gained from study, investigation, or instruction. Internal standards: Performance measurement systems have pre-specified data quality standards tailored for individual performance measures. These standards address the entire process by which the data are collected, stored, and transmitted by participating health care organizations. Depending on the source of data, the standards may emphasize different sets of issues as specified: administrative data-coding accuracy and consistency, missing data, data conversion error; clinical/case record-based data-presence, accuracy, timeliness, legibility, authentication, sampling method, data entry and abstract; and survey-based data-sampling method, sampling error, response rate. Line graph: A tool that shows basic trends in process over time. Data points are plotted by time or sequence on the horizontal axis and the increments of measurement on the vertical axis and then connected with a line. Mean: A measure of central tendency for a continuous variable measure. The mean is the sum of the values divided by the number of observations. Measure: To collect quantifiable data about a function or process. Median: The value in a group of ranked observations that divides the data into two equal parts. Mode: In statistics, a measure of central tendency of a collection of data consisting of the measurement of the data set that occurs most often. Data Display | Slide 48 © Joint Commission Resources, Inc. Measurement: The systematic process of data collection, repeated over time or at a single point in time.
Turning Data into Useful Information Data Display Outcome: The result of the performance of a function or process. Outcome measure: A measure that indicates the result of the performance of a function or process. Outcome Measurement: The process of systematically tracking a patient’s clinical treatment and responses to that treatment for the purpose of improving are. Pareto chart: A form of vertical bar graph that displays information in such a way that priorities for process improvement can be established. It shows the relative importance of all the data and is used to direct efforts to the largest improvement opportunity by highlighting the vital few in contrast to the many others. Performance: The way in which an individual, a group, or an organization carries out or accomplishes its important functions and processes. Performance improvement: The continuous study and adaptation of a health care organization’s functions and processes to increase the probability of achieving desired outcomes and to better meet the needs of patients and other users of services. This is the third segment of a performance measurement, assessment, and improvement plan. Performance improvement plan: A documented description of an organization’s approach to identifying and achieving performance improvement goals. Often, the performance improvement plan contains a section that is dedicated to performance measurement. Performance matrix: A tool to view current performance in a process in relation to its importance. Performance measure: A quantitative tool that provides an indication of an organization’s performance in relation to a specified process or outcome. Performance measures, or indicators, are the fundamental building blocks of a performance measurement system. Sometimes called an indicator. Performance measurement: The collection and analysis of data about the performance or operations of key processes. Process measure: A performance measure that is used to assess the operations of goal-directed, interrelated series of actions, events, mechanisms, or steps. Quality control: The performance of processes through which actual performance is measured and compared with goals, and the differences is acted on. Quality improvement: An approach to the continuous study and improvement of the processes of providing health care services to meet the needs of individuals and others. Synonyms include continuous quality improvement, continuous improvement, organization wide performance improvement, and total quality management. Lesson 3 | Slide 49 © Joint Commission Resources, Inc. Process: A goal-directed, interrelated series of actions, events, mechanisms, or steps that transform inputs into outputs.
Turning Data into Useful Information Data Display Radar chart: A two-dimensional chart, of three or more quantitative variables represented on axes starting from the same point, that graphically shows the size of gaps among five to ten organizational performance areas Range: A measure of the spread of a data set. The difference between the smallest and largest observation. Rate: Derived by dividing the numerator by the denominator within a given time frame. In other words, the numerator is the subset of the denominator. Ratio: A relationship between two counted sets of data, which may have a value of zero or greater. In a ratio, the numerator is not necessarily a subset of the denominator. Reliability: The ability of the indicator to accurately and consistently identify the events it was designed to identify across multiple health care settings. Run chart: A display of data in which data point are plotted as they occur over time to detect trends and other patterns and variation occurring over time. Run charts, as opposed to tabular frequency displays, are capable of time-order analytic studies. Sampling: The process of selecting a group of units, portions or material, or observations from a larger collection of units, quantity of material, or observations that serves to provide information that may be used as a basis for making a decision concerning the larger quantity. Scatter diagram: A graphic representation of data depicting the possible relationship between two variables. This diagram displays what happens to one variable when another variable changes to test a theory that the two are related. While times diagram cannot prove that one variable causes the other, it does clarify whether a relationship exists, and the strength of that relationship. Sentinel event: An unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof. Serious injury specifically includes loss of limb or function. The phrase or risk thereof includes any process variation for which a recurrence carries a significant chance of a serious adverse outcome. Standard deviation: A measure of variability that indicates the spread of a set of observations around the mean. Stem & leaf plot: A tool used to display raw data for evaluating a process. Data Display | Slide 50 © Joint Commission Resources, Inc. Special cause variation: the variation in performance and data that results from special causes. Special cause variation is intermittent, unpredictable, and unstable. It is not inherently present in a system; rather, it arises from causes that are not part of the system as designed. It tends to cluster by person, place, and time and should be eliminated by an organization if it results in undesirable outcomes.
Turning Data into Useful Information Data Display Stratum chart: A multi-layered line graph that displays cumulative data over time. Each layer represents different data and the entire graph shows both the total and the components. Survey: A tool to obtain data about patient satisfaction or perception of care. Theory of normal distribution: A theory that holds that all measurement data points within a sample form a symmetrical pattern, and the greatest number of points is group around the center (a bell curve). Three T’s: A way to facilitate data analysis by trending data over time for each indicator; target range of performance for each indicator; and together look at the indicators in combination. Validity: The ability to identify opportunities for improvement in the quality of care and demonstration that the use of indicators results in improvements in outcomes and/or quality of care. Variance: A measure of the difference in a set of observations. Data Display | Slide 51 © Joint Commission Resources, Inc. Variation: The fluctuation or difference in process performance and outcomes. Sources of variation in health care include patient factors, practitioner factors, organization factors, factors related to the external environment, and chance. Two distinct types of variation exists: common cause and special cause.
