Primary Care Access

Improving access is all about getting supply and demand in equilibrium, which means that there is no backlog of appointments and no delay between when the demand is initiated and when the service is delivered.

 

The gap between supply and demand not only contributes to a delay in meeting patients’ needs, but it can also be expensive and generate waste in the system.  The experience of many health care organizations demonstrates that demand is not really insatiable, but actually predictable.  In fact, the demand for any kind of service — appointment, advice, or message to a provider — can be predicted accurately based on the population, the scope of the provider practice and, over time, the particular practice style of each provider.  Periods of high or low demand can be anticipated, based on an analysis of demand data collected on all requests coming into the system.  An improved access system uses these predictions as the framework to match its supply to the needs of a population of patients for any specific service. 

 

There are ten recommended changes (see below) that clinical office practices can use to bring their supply and demand into equilibrium.  While there is no prescribed order that should be followed in testing and implementing the changes, many practices begin with measuring and understanding their current supply and demand.  This will demonstrate the extent of the mismatch between supply and demand (if one exists) and help practices select the changes that may be the highest leverage ones for them.

Measure and Understand Supply and Demand
Understanding the patterns of both demand and supply on a weekly, monthly, or seasonal basis allows for focused efforts to shape demand to match supply, and/or increase (or decrease) supply during periods of high (or low) demand.

Recalibrate the System by Working Down the Backlog
Backlog consists of appointments on the future schedule that have been put off due to lack of space on the schedule to do this work sooner; working down the backlog recalibrates the system to improve access.

Balance Supply and Demand on a Daily, Weekly, and Long-Term Basis
The foundation of improved access scheduling is the matching of supply and demand on a daily, weekly, and long-term basis.

Create Contingency Plans
The natural variation in supply and demand that occurs as part of the everyday functioning of a practice often creates problems that contingency plans can address.

Manage Panel Size and Scope of the Practice
Managing panel size and the scope of the practice allows a team to balance supply and demand and ensures that they can do today’s work today.

Decrease Demand for Appointments
Reducing the amount of demand makes it easier for the system to absorb current or future levels of demand.

Optimize the Care Team
Optimizing the care team is critical to maximizing the supply of the clinic and improving the daily flow of work.

Reduce Scheduling Complexity
Complex schedules, with many appointment types, times, and restrictions, can actually increase total delay in the system because each appointment type and time creates its own differential delay and queue. Reducing the complexity ultimately decreases system delays.

Predict and Anticipate Patient Needs
To ensure that patient needs are met and that patients flow smoothly through the clinic process, staff look ahead on the schedule to identify patient needs for a given day or week.

Improve Work Flow and Remove Waste
Improving the flow of work and eliminating waste ensures that the clinical office runs as efficiently and effectively as possible.

These changes were developed in conjunction with the Veterans Health Administration (VHA) through their Advanced Clinic Access Initiative. The changes were applied and refined in clinical practice through IHI's work with the VHA from April 2001 through December 2002.
