Healthcare providers deal with a lot of data. This data is often stored across a variety of legacy systems that don't communicate with one another that well. Not only do data discrepancies eat up medics' time (think: ), but they also influence the quality of care. You know it better than anyone: drawing a complete picture of what a patient has and is experiencing health-wise is the first step toward correct diagnosing and effective treatment. To fend off healthcare data disparities, medical organizations have long been turning to and . The aim? Bring siloed data together into single, consolidated storage — a healthcare data warehouse — and use it to draw insights. This blog post covers vital aspects of adopting a data warehouse in healthcare, zooming in on its technical characteristics, highlighting the value a centralized data storage can drive for medical organizations, and providing a high-level data warehouse implementation roadmap. nine hours per week data management data analytics providers What is a healthcare data warehouse? A healthcare data warehouse serves as a centralized repository for all the healthcare information retrieved from multiple sources like electronic health records (EHR), electronic medical records (EMR), enterprise resource planning systems (ERP), radiology and lab databases, or wearables. The data in the warehouse is transformed to fit unified formatting, so it can be used for analysis with no additional preparation. The healthcare warehousing market: highlights The global healthcare data storage market is predicted to grow from $3.08 billion in 2020 to $6.12 billion by 2027 at a CAGR of 10.7%, a . The increased interest in data warehousing solutions among healthcare industry players can be primarily traced back to: study by BlueWave Consulting reports The surge in the volumes of digital data generated by healthcare organizations The broader use of EMR, EHR, and CPOE The more extensive adoption of connected medical devices generating streaming data The call for enhanced operating efficiency brought about by COVID-19 Healthcare organizations around the globe are thus increasingly investing in data warehousing solutions. They seek to alleviate the difficulties related to managing the ever-growing amounts of clinical data and reach higher operational efficiency by , prescriptive analytics, and clinical process automation. tapping in predictive analytics A healthcare data warehouse: value proposition The value a healthcare data warehouse drives for a medical organization comes from three principal directions: Digitization and automation. With fast access to all kinds of healthcare data, from insurance claims to admission forms to lab test results, healthcare providers optimize and even . automate stakeholder journeys Innovation. Drawing on the capabilities of centralized data storage, healthcare organizations can implement new use cases in the fields of predictive analytics, prescriptive analytics, and . the Internet of Medical Things Achieving strategic objectives. Saving up medics' time, speeding up healthcare operations, and putting the insights gained with analytics to use, healthcare facilities can improve the quality of healthcare services, , and expand the range of care delivery options. reach out to more patients Here's are a few examples of how medical institutions may draw on the capabilities of a clinical data warehouse and accompanying analytics tools to realize the opportunities above: Clinicians may analyze the data gained from multiple doctors to identify best practices in diagnosing and treating illnesses and chronic conditions. Spotting those doctors whose patients have better outcomes and drilling down to the patient level can help develop more effective treatment protocols. Having all the patient data accessible from one place, doctors may develop more personalized care plans. The transparency of anonymized clinical outcomes may foster collegial collaboration and competition, thus motivating the healthcare staff to deliver high-quality care. Tapping into continuous patient feedback loops can help respond to patients' needs faster. Clinicians may test the effectiveness of screening methods to enable the shift toward preventive care. Doctors may monitor the population's health over time to predict epidemics and exacerbations of chronic conditions. Administration may gain insight into how well a healthcare institution performs, develop benchmarks against which the performance can be measured, optimize financial management, and facilitate other administrative operations. Hospitals and other medical institutions can benefit from enhanced reporting opportunities for internal management and external audits, including regulatory compliance checks. The architecture of a healthcare data warehouse The architecture of a healthcare data warehouse comprises the following layers: Data source layer that consists of clinical, admin, research, precision, patient-generated, and other data from internal and external sources Staging layer that stands for temporary storage, where the data from multiple sources undergoes an extract, transform, load (ETL) or an extract, load, transform (ELT) process and gets combined into a single, consistent body of data. Data storage layer that acts as centralized storage for integrated data. The layer may encompass data related to multiple subject areas or consist of subsets designated to specific areas or departments, known as data marts. Data analytics & reporting layer that comprises data analytics and business intelligence systems for descriptive, predictive, and prescriptive analytics, as well as reporting, , and dashboarding tools. visualization The features of a healthcare data warehouse to prioritize Sensitive by nature, healthcare data requires proper handling. A healthcare data warehouse should meet specific requirements to guarantee patient safety and secure healthcare providers from potential liabilities. The features we recommend paying particular attention to span: Data security and compliance US federal laws, such as HIPAA, and state laws require organizations managing healthcare data to implement security safeguards for protecting personally identifiable information from disclosures and unauthorized use. Trusted ways to ensure data security include: Designing a and setting up data governance procedures to secure sensitive information from being accessed by unauthorized people. Data governance can be implemented by creating read-only replicas, setting up custom user groups with pre-defined access rights, or encrypting personally identifiable information. data management strategy Setting up raw-level permissions to restrict users from viewing specific data entries. Setting up raw-level permissions by account or patient ownership, for example, would give a particular doctor access to their patients' records, still preventing every doctor from accessing every patient's personal health information. Setting up permissions at the data analytics and BI level to ensure sensitive data won't be inappropriately shared through a dashboard or report. In addition, we recommend performing systematic vulnerability assessments to prevent and timely close any security loopholes. Data integrity The data in a warehouse only creates value when it is clear, unambiguous, correct, and transformed to fit an established data model. Data integrity is accomplished through ETL or ELT processes. The critical difference between the two is that with ETL, the data is transformed before reaching the target system, usually at the staging server, while with ELT, the data undergoes transformation once it's loaded into the warehouse. Depending on the types of an organization runs on top of a data warehouse, it makes sense to prioritize either ETL or ELT. healthcare solutions is easier to implement, and it's a good fit for use cases with moderate data volumes. However, the process is time-intensive, and the processing time grows together with the data volumes. An ETL engine , in turn, is a good option for use cases dealing with vast amounts of data. Since raw data is loaded into the target system once, the transformation process is faster, and the processing speed does not depend on the volume of incoming data. An ELT engine Data warehouse performance When it comes to manipulating health-related information, particularly streaming data generated by connected medical devices, glitch-free performance is vital. A healthcare data warehouse can be amplified with the following features to ensure fast and consistent transmission, querying, and retrieval of data: Bitmap indexing that reduces response times of ad hoc queries and boosts data warehouse performance Parallel task execution that allows breaking down complex querying operations into multiple smaller, hence, faster processes Elastic scaling of cloud resources that allows growing or shrinking cloud storage and computing power dynamically in response to workload demands Automated data backups that foster disaster recoveries in case of potential incidents. Vital integrations to implement A healthcare data warehouse drives the most value when it serves as a part of a broader ecosystem comprised of the following interoperating components: A repository for unstructured and semi-structured data, a data lake may serve as a source of raw data for training machine learning models. A data lake. may run on the cleansed and structured data stored in the data warehouse, enabling descriptive analytics and supporting decision-making. Business intelligence. BI solutions may help realize predictive and prescriptive analytics, fostering diagnosing and treatment and optimizing hospital operations. Machine learning. Bringing ML to healthcare A healthcare data warehouse implementation roadmap Implementing a healthcare data warehouse is, without a doubt, a complex undertaking. We've put together a healthcare data warehouse implementation roadmap to alleviate the struggles medical organizations stumble upon when rolling out healthcare warehousing solutions. The entire data warehouse implementation process can be broken down into four steps. The crucial step in the whole data warehouse development process defining all the future efforts, the planning stage deals with assessing the context and thinking over the strategic aspects of adopting a clinical data warehouse. The tasks to carry out include: 1. Planning Define the needs of individuals involved in the data management process and uncover data management bottlenecks or areas of improvement Analyze the available IT infrastructure Formulate the strategic objectives you aim to achieve by implementing a data warehouse and map those to what you’ve learned Put together a vision of a future data warehouse and draft an adoption strategy, outlining critical functional and non-functional aspects, including regulatory compliance, security, and performance requirements to a future healthcare data warehousing solution Plan infrastructure and human resources needed to realize the vision. At the design stage, craft the architecture of a future data warehouse, define data integration procedures, think over the healthcare data warehouse model, and plan for the necessary integrations. More specifically, 2. Design Decide upon a data integration strategy and design the ETL or ELT processes. Define the data model: The enterprise-wide data model incorporates the data from multiple subject areas and gives additional opportunities to match up data sets from all organization's departments The data mart model includes subsets dedicated to specific areas or departments The late-binding data model does not sort data into discrete categories but keeps it freely flowing, allowing data scientists to develop new querying capabilities on the go Design data validation procedures Design the necessary integrations The development stage involves rolling out the necessary infrastructure components and coding and implementing data warehousing software and end-user applications. Along with ongoing accompanying development activities, additional validation is needed post-migration. A set of checks are run to validate the migrated data for duplicates, errors, contradictions, or inaccuracies. 3. Development & deployment 4. Ongoing and post-migration testing testing activities On a final note Data warehousing is becoming vital to providing value-based, personalized care, improving overall patient experience and optimizing clinical processes. The pandemic has only accelerated the need for change and sparked the transition toward a more integrated and thoughtful approach to managing healthcare data. As more medical organizations initiate data warehousing projects, it is vital to remember that a data warehouse on its own is not a cure-all. To discover the full value of a clinical data warehouse, it is necessary to develop a thought-out data management strategy aligned with the organization's strategic objectives and treat a data warehouse as a part of a broader, interoperating analytics ecosystem.
