On-Call Scheduling – Trying for Equity
Of the many difficulties facing cardiac cath labs involved in on-call work, there is little written about being on call. Yet there is a lot of discussion and distress about on-call scheduling. The major point generally seems to be that the on-call schedules are not fair. Indeed, the lack of an “equitable” distribution of on-call schedule assignments is a morale dropper.
“Why do I have more on-call than the next person on this schedule? This is not justifiable. I always get stuck with on-call…[grumble, grumble].” And so it goes!
Some cardiac cath labs’ approach to on-call scheduling is with a request book, a committee, or supervisor determination of the on-call scheduled for one or two months in advance. This strategy allows the staff to request specific days “on” or “off” of call to accommodate known family events, doctor’s appointments, etc. The great disadvantage is that cardiac cath lab staff can never predict very far in advance when they will be working. In addition, much time and effort are required to try to provide a fair distribution of on-call responsibility. Many of us know that even a little difference in assigned on-call can cause a great ruckus among the cardiac cath lab staff.
Let me describe how it works. There are an infinite number of repeating patterns possible. Many, however, do not develop complete equity for a significant period of time. Below, I have described a simple method for generating multiple, rotating schedule templates, all
To create a rotating template:
1. Begin with a grid of “n” weeks, where “n” is the number of on-call staff in the group. Let’s do an example with nine (9) staff members. Therefore, there would be nine (9) weeks for the grid.
3. Repeat the same pattern over and over again, but move down 1 week to start the pattern for the next person.
When the pattern has been determined for first call person, it is duplicated for the next, but shifted forward one week. In other words, call person 2 replicates the exact same pattern, but begins it in week 2 of your grid (Figure 1b). Return to the top of the grid when the bottom is reached.
This pattern is repeated, always shifting forward one week, until the last on-call person, number 9, has been assigned. My call team requires three (3) staff on call. The pattern shown in Figures 1a-c runs such that persons 1, 4, and 7 will share the same call days in this schedule.
This pattern is equitable. Staff will complete filling the schedule for on-call and will always have, in this example, 21 days of on-call, regardless of the initial pattern chosen. Since each on-call person has one pattern and only one pattern in the grid, it is equal, and since the grid may be repeated multiple times, it is rotating and hence predictable.
To provide change in personnel interactions, have the nurses’ schedule shift down 1 week and have the technologists shift up 1 week in the rotation of labs. That would provide a mix that would be equitable and predictable as well.
There are other consideration that must be accounted for. After everyone is scheduled equitably following the rotating pattern, at this point, we incorporate the individual needs or preferences and holidays regarding on-calls. The on-call can be traded or given to another person. The originally assigned staff member is responsible for coverage. It does not matter that someone is covering for you; you have ownership of providing on-call for that date. If you don’t help others and provide coverage when they need help, don’t expect help when you want someone to cover an on-call for you.
This is the devil in the details. The smaller the staff, the less leeway you have to negotiate. This is where relationships are strained. Compromise is the goal. With an equitable, rotating, long-term schedule, more opportunities for trading exist. We all want to control our lives. We are a special breed — we work in the cardiac cath lab and our work is to serve and save lives at all hours, both day and night. We make that sacrifice of family time and sleep, and are willing to work from daylight through the night until daylight again to save cardiac muscle and a life.
In some states, regulations are pending that say after 18 hours of work there must be at least an eight (8)-hour break. Eighteen hours can easily happen after a day of work with late cases. Add in a few emergency cases, and you have reached 18 hours of work. I remember (maybe not so clearly) a thirty-seven hour day. Based on existing evidence, caution should be exercised whenever an assignment is expected to exceed 12 hours in a 24-hour time period or 60 hours in a 7-day time period. Health care worker fatigue and patient safety is a growing concern and Joint Commission is beginning to focus on this area. The on-call schedule may require a larger pool of staff to provide ample staffing for coverage.
There are many options or solutions to on-call scheduling. You must find one that is equitable, fair, and easy to predict, in order to avoid the rumble and grumble of a staff that sees you as being unfair. Be courageous and strong. My suggestion may work for your cardiac cath lab. I like predictability, too!
