    Study Notes

    Section 6: Health Data Analytics

    • Data analytics is a process and practice of analyzing data to answer questions, draw information and insights, identify trends, and make decisions.
    • Organizations invest in infrastructure to collect, analyze, and report data related to quality, safety, and performance.
    • The foundational steps in data management systems include: planning, data collection, interpretation, use, ongoing study, action, monitoring, and reporting.
    • Data are the representation of things, facts, concepts, and instructions stored in a defined format and structure on a passive medium (e.g., paper, computer, microfilm).

    Health and Data Informatics

    • Data analytics is essential for quality improvement in healthcare delivery.
    • The 1880s-1990s saw key developments: Taylor's work on workflow, predictive analytics, and data-support systems.
    • Information systems like relational databases (1970s), data warehousing (1980s), data mining (1990s), electronic health records (EHRs) in the 2000s and beyond have shaped health data analysis and implementation.
    • The increased use of electronic health records (EHRs) in the 2000s and ongoing have also influenced modern data analysis and decision-making processes and prompted the development of big data analytics, artificial intelligence, and machine learning (AI/ML) to improve quality and safety.
    • Continuous improvement in data management is necessary, including data validation, data quality, and security measures.

    Data Analytics

    • Data are a valuable asset for organizations seeking to improve their performance.
    • Big data is a significant factor in many aspects of healthcare, driving outcomes and value-based care.
    • Organizations use data across systems to support improvements in staff, customers, and finances.
    • Big data, in the context of healthcare, consists of large data sets characterized by volume, velocity, and variety along with veracity, variability, and vulnerability.
    • Data analytics is now more central to the process of healthcare than ever before and the principles outlined here all relate to the impact on that analysis and outcome measures. The DIKW pyramid (Data-Information-Knowledge-Wisdom) demonstrates the progression of using data to make decisions.

    Data for Improvement

    • Healthcare quality professionals encounter challenges in interpreting and distinguishing relevant, meaningful, and critical data for improvement planning.
    • Several activities to improve data use include assessing the data use context, engaging data users, improving data quality, enhancing data availability, identifying information requirements, building capacity, strengthening data infrastructure and processes, and ensuring appropriate use and handling of data.
    • Differentiating between data and information is important; data are stored representations of information, while information is actionable data.

    Information Systems

    • Information systems within healthcare support various activities, including managing financial data (payroll, accounts payable), human resources data (hiring, employee records), and office operations (scheduling, email).
    • Healthcare information systems include clinical information systems (EHRs, patient/provider databases) and management information systems (MIS) as well as systems for financial management and reporting.
    • Decision support systems can facilitate cross-functional analysis and support strategic planning, resource allocation, and performance monitoring using data generated across a system; various types of data (including patient information, financial records, operational data) are used to improve the processes.
    • Distributed Health Data Network (DHDN) is about data sharing across organizations to improve health services and research; data governance protocols, procedures, and agreements in addition to technical security measures, are essential to protect the ethical handling of data and ensure patient privacy.

    Measurement Concepts

    • Reliability of data-collection instruments is the degree to which measurements are consistent (e.g., test-retest and inter-rater reliability). Measures of reliability often use statistical methods to assess consistency of the data over many testing sessions.
    • Validity of measurements reflects the extent to which a tool measures what it is intended to (e.g., content, construct, and criterion validity). Validity encompasses the soundness of the data itself, and includes examining the measure's conceptual meaning and its use in assessing the construct.
    • Understanding data types, such as nominal, ordinal, interval, and ratio, is crucial to interpreting and using data effectively within healthcare analysis and improvement tasks.

    Data Types

    • Nominal data are categorical with no intrinsic ordering.
    • Ordinal data are categorical but with an intrinsic ordering.
    • Interval data are scales with consistent intervals but no true zero point.
    • Ratio data are scales with consistent intervals and a true zero point.

    Sampling Design

    • Probability sampling is where every member of a population has an equal chance of being selected (simple random, systematic, stratified, cluster).
    • Non-probability sampling is where the chance of selection is not known (convenience, snowball, purposive, quota).
    • Considerations for sample size include research purpose, anticipated differences in groups, and population size.

    Statistical Techniques

    • Statistical tests evaluate the significance of relationships between variables (parametric and non-parametric tests, including t-tests, chi-square tests, and use of confidence intervals). These tests determine if the observed differences or relationships could be due to chance alone. Statistical tests are applied to assess the reliability and validity of the data, as well as to assess changes over time.

    • Measures of central tendency summarize a data set by finding the typical value (mean, median, and mode).

    • Measures of variability outline the spread or dispersion of the data (range, variance, and standard deviation).

    Data-Informed Decision Making

    • Data informs decision making for healthcare improvement, with the concept that data leads to information, knowledge and finally wisdom as outlined in the DIKW pyramid. Data-informed decision-making uses methods of reporting, visualization, understanding, and acting.
    • A variety of methods are used to display data, such as charts, histograms, tables, infographics, and also using software that allow various visual representations emphasizing visual clarity and interpretation.

    Design and Management

    • Quality, safety, and performance improvement involve rigorous evaluation and using data to make decisions and take steps to improve (including the use of data, software tools and databases). Organizations utilize tools and databases for effective data management. This also includes developing robust data collection procedures and improving data quality.
    • Strategies are developed carefully for reporting, disseminating and acting on the data in multiple ways. Dashboards and balanced scorecards are essential tools for visualizing and tracking organizational performance data to guide and drive decision-making processes and make improvements.
