In many primary care clinics, patients often wait a long time before seeing a healthcare professional. These delays come from problems like blockages in triage areas, treatment rooms, or diagnostic services. Long wait times make patients unhappy, raise clinic costs, and can worsen patient health because important care is delayed.
Healthcare administrators have tried different ways to measure and improve patient flow. Older methods used agent-based models that copy individual patient behavior, but these models often miss the full details of how clinics work. Researchers like Nathan Preuss and his team at the University of Oklahoma created network flow models. These treat patient movement and treatment spots as points connected by networks. This method can spot bottlenecks more clearly by studying flow data and making changes in clinic layouts or staff to improve how things run.
But making accurate models needs data that shows real conditions without revealing private patient information or relying on incomplete hospital records. Synthetic data is important here.
Synthetic data is made-up information that copies the statistical parts of real patient data but does not have any actual patient details. Because it looks like real healthcare data, synthetic data lets analysts simulate patient flow while protecting privacy and following privacy rules like HIPAA and GDPR.
Synthetic data helps solve two main problems:
In practice, synthetic data is created by methods like statistical modeling, machine learning, and deep learning. About 72.6% of synthetic data tools in healthcare use deep learning because this approach can capture complex patterns in data types like tables, images, and time series.
Synthetic data lets healthcare operations simulate rare events or unusual patient volumes safely. This helps test operation methods without risking patient privacy or safety.
Simulation has been used for a long time to model and improve patient flow. The main technique is Discrete Event Simulation (DES). DES shows healthcare as a series of events at certain times, like patient arrival, triage, consultation, tests, and discharge. It gives details on how resources are used, staff workloads, and patient waiting times.
When synthetic data is used with DES and other tools, many scenarios can be tested with different factors like staff numbers, room capacity, or patient demand. Researchers can find which setups reduce bottlenecks and cut wait times without overburdening the clinic.
Generative AI (GenAI) helps by automating synthetic data creation and building complex models. AI tools like TensorFlow and PyTorch make realistic patient profiles, appointment schedules, and treatment times that look like real clinic data. This helps healthcare managers predict how changes—like adding phone automations or hiring more staff during busy times—will affect efficiency.
Digital twins are another technology that create virtual copies of clinical environments and update them with real-time data. Adding synthetic data to digital twins lets administrators test different patient flow and resource setups virtually before making changes. Companies like GE Healthcare and Philips HealthSuite use these for planning and treatment work.
AI and synthetic data are also used to automate front-office jobs, especially phone answering and scheduling. U.S. companies like Simbo AI use AI to handle phone calls, book appointments, and send reminders. This lowers admin work and mistakes.
AI phone systems collect real-time data about when patients call, why, and appointment openings. Using this with synthetic data helps clinics model patient call patterns and improve resource use. For example, if mornings have many calls, clinics can add more automated responses then.
Automation improves both patient experience and office efficiency. Tasks like filling forms, checking insurance, and confirming appointments become faster and less error-prone. This reduces patients missing or cancelling appointments, which helps clinic revenue and care.
AI linked with simulation models can predict busy times and help schedule staff. Simbo AI’s system can connect with scheduling tools to alert staff to adjust hours or duties to keep patient flow smooth.
Automating repetitive tasks frees staff to focus on patient care and clinical support. When combined with patient flow models, this helps balance workloads and improve the clinic environment.
Healthcare providers in the U.S. use several AI tools and platforms to make synthetic data and run patient flow simulations:
Many of these tools are open-source, helping small clinics and big hospitals use them. Python is the main programming language for synthetic data, used in over 75% of healthcare AI projects. This makes it available to many technical experts.
While synthetic data and AI simulations offer benefits, healthcare leaders must consider some challenges:
Despite these issues, many U.S. healthcare groups have used synthetic data and simulation well, improving clinic work and patient care.
Clinic managers in the U.S. can use synthetic data and patient flow simulation in several ways:
In U.S. healthcare operations, synthetic data is an important tool to model patient flow and improve efficiency while lowering wait times. It allows privacy-safe and realistic simulations of clinic work. This helps leaders and IT staff make better decisions. When combined with AI and automation, synthetic data helps clinics plan staff, resources, and patient communication. This leads to better patient care and reduces costs. As technology grows, using synthetic data and simulations is a practical way for clinics to improve services.
The article addresses long wait times in primary care clinics, which are caused by operational inefficiencies and bottlenecks, affecting patient satisfaction and health outcomes.
The article constructs a network flow model to better identify bottlenecks in patient flow and wait times by analyzing flow metrics associated with various nodes in the healthcare network.
By changing the topology of the network flow model, the authors are able to identify and eliminate bottlenecks, thereby increasing overall efficiency and reducing patient wait times.
The model’s edge capacities are taken from an agent-based model based on a case study of a primary care clinic, sampled as random variables.
The model is subjected to ensemble runs to account for uncertainty in the data and includes sensitivity analyses to evaluate its robustness.
The authors emphasize the methodology of using a network flow model rather than the specific results, aiming to establish a framework for optimizing patient flow.
Synthetic data allows the authors to model various operational scenarios in a primary care clinic, facilitating the examination of different patient flow conditions.
Patient wait time is a critical metric analyzed within the network flow model to evaluate and improve clinic efficiency and patient satisfaction.
The model can be optimized to minimize individual patient wait times or the overall wait times across the patient network, depending on operational goals.
The study’s findings can inform healthcare practitioners and administrators about strategies to enhance operational efficiency in clinics, leading to better patient outcomes.
