Healthcare in the United States faces many problems. These include staff shortages, inefficient operations, and unpredictable patient behavior. These issues are most common in primary care clinics. One big problem is patients missing appointments, called no-shows. No-shows cause lost work time, wasted resources, and longer waits for patients. Clinic managers want to improve how they schedule appointments and use their resources. New simulation methods, combining Agent-Based Simulation (ABS) and Discrete-Event Simulation (DES), help make better decisions and run clinics more smoothly.
This article explains how these two simulation methods work together. It also talks about Artificial Intelligence (AI) and how it can automate clinic work. For example, AI phone services like those from Simbo AI help clinics by improving patient communication and saving staff time.
Clinics have many steps that affect patients and care quality. Simulation models create a virtual clinic where new ideas can be tested safely before using them in real life.
Discrete-Event Simulation (DES) shows the healthcare system as events that happen at certain times. Events include patient check-in, seeing the doctor, tests, and check-out. DES tracks how patients move through the clinic and how staff and rooms are used. It helps find delays and busy times in the clinic’s processes.
Agent-Based Simulation (ABS) looks at individual people within the system. These can be patients or staff members. ABS shows how people behave and interact, such as when patients arrive, staff schedules, or unexpected no-shows. This method gives details about how each person’s actions affect the clinic.
Using DES and ABS together gives a full picture. DES shows the overall process and resources, while ABS shows different behaviors of patients and staff. Together, they help clinic managers create models that match real clinic operations day by day.
In US primary care clinics, about 17.8% of patients do not show up for their appointments. This causes clinics to lose time and have longer waits. For example, a family medicine clinic with about 28,000 visits a year before COVID-19 had many problems due to no-shows.
A study by Yuan Zhou and others made a hybrid model. It used machine learning to predict which patients might miss appointments. Then it used DES and ABS to simulate clinic operations in detail.
The model tested these scheduling methods:
Results showed that prediction-based double-booking worked best. It balanced how many patients the clinic could see and how fast the visits were. This method filled slots more carefully and did not increase patient waiting much.
The study also showed why it is important to model both system processes and individual behaviors. Combining these models with predictions helps make better decisions and saves money.
Simulation works well when it includes natural variations in clinics, like how long each step takes or when patients arrive. For example, emergency departments (EDs) face many challenges in patient flow and resource use. A review by Ouda, Sleptchenko, and Simsekler showed how DES and ABS together help manage these complex flows. This is similar in primary care clinics, where appointment types, arrivals, and availability change often.
Involving healthcare workers in building and checking simulation models is very important. They help make sure the models reflect real practice. This increases trust and makes it more likely that clinics will use the simulation results.
Many healthcare models look only at overall outcomes, like health results. They rarely help with daily decisions like scheduling or managing no-shows. This limits their use for clinic management.
The hybrid approach, using ABS, DES, and machine learning, solves some problems:
This helps clinics reduce missed appointments and avoid overbooking errors.
AI and automation tools are now part of healthcare operations. They help clinics work more efficiently and improve patient communication.
One example is Simbo AI, which automates front-office phone calls. It helps with appointment reminders and patient questions. This reduces the load on staff and lowers no-show rates by keeping patients informed.
AI tools combined with simulations create smart automation systems:
For busy clinics, using simulations with AI gives ways to schedule well and manage resources while improving daily communication.
The model used in a family medicine clinic can work in many primary care settings. This includes clinics that serve vulnerable people who may find it hard to keep appointments. These clinics often have limited staff and money. Using simulation and AI automation can help them run better and improve patient access.
Besides primary care, emergency rooms and specialty clinics can also benefit. Research shows that emergency care often does not use these combined models enough. Simulation can help reduce crowding, shorten waits, and improve care.
Hybrid simulations are useful because they include both system processes and individual behaviors. This helps clinics respond to changes in patients’ needs and staff schedules.
As demand grows and staffing remains short, mixing simulation methods with AI automation offers a practical way to manage resources better and make patient experiences smoother.
Healthcare leaders play a key role in using simulation and AI tools. Their tasks include:
By doing this, clinics in the US can use data to handle daily challenges and improve both money management and patient care.
US healthcare clinics can improve operations by combining agent-based and discrete-event simulations with AI automation. These methods help clinics create better schedules, use resources well, and keep patients informed. For healthcare managers, owners, and IT staff, using these tools is important to meet growing demands and run clinics more efficiently.
The main challenge addressed is managing patient no-shows and operational uncertainties that lead to inefficiencies, loss of productivity, and poor patient outcomes. The approach aims to improve scheduling and operational decisions to mitigate these impacts.
It integrates predictive analytics with simulation modeling (agent-based and discrete-event) to generate accurate inputs and realistically simulate clinic operations, enabling evaluation of different strategies and targeted interventions for improved primary care management.
Patient no-show prediction provides critical input data that informs simulation modeling, enabling the design and evaluation of tailored double-booking strategies that better balance clinic productivity and efficiency.
The modules are predictive analytics, simulation modeling (combining discrete-event and agent-based simulation), and decision evaluation, which together support informed, simulation-based decision-making.
The prediction-based strategy achieves a superior balance between productivity (daily patient throughput) and efficiency (visit cycle time and patient wait time), outperforming random and designated-time double-booking approaches.
This hybrid simulation better captures both system-wide processes (discrete-event) and individual-level behaviors (agent-based), providing a more accurate and realistic representation of clinic operations to improve decision quality.
Existing models primarily focus on aggregated system levels rather than individual behaviors, mostly predict clinical outcomes not operational variables like no-shows, and do not directly optimize operational decisions.
The case study showed that prediction-informed double-booking reduces the negative impacts of no-shows, improves patient flow, and enhances operational outcomes in a socioeconomically challenged patient population.
The conceptual framework and integrated methodology can be adapted to other healthcare settings to support operational decisions by customizing predictive models and simulations to specific workflows and challenges.
Benefits include improved clinic productivity, reduced patient wait times, better resource utilization, enhanced patient satisfaction, and overall more cost-effective primary care service delivery.
