Hygiene reappointment rate

What it is

Hygiene reappointment rate is the share of patients seen in hygiene during a period who have a future hygiene appointment booked.

Practices define "booked" in different ways. The strictest rule counts only patients booked before they leave the office. A looser rule also counts patients booked within a few days by follow-up.

Why operators track it

• Retention. A patient with a next visit booked is more likely to return than one told to call later.
• Schedule planning. Reappointments fill the hygiene schedule months ahead.
• Front office follow-up. The patients who were not booked make a clear call list.
• Treatment. Hygiene visits are often where treatment needs are found, so missed visits can mean missed care. (This is a general observation, not a measured figure.)

How it is calculated

Hygiene reappointment rate = hygiene patients with a future hygiene appointment ÷ hygiene patients seen

• Count unique patients, not visits.
• Decide the rule for "booked": before leaving, or within a set number of days.
• Count only future appointments of a hygiene type.

Worked example

In one example month, 400 patients were seen in hygiene. 352 left with their next hygiene visit booked. The front office booked 28 more within 7 days. 20 were not booked.

How to read it

• Look at the gap between the two rules. A big gap means booking is happening by follow-up rather than at checkout.
• Look by hygienist and by day. Low rates on certain days can point to checkout workflow, not the clinician.
• Patients who should not be counted. Patients moving away or transferring care lower the rate. Some practices exclude them. Say if you do.
• We do not publish a benchmark. Rates depend on the patient base and the rule used.

Definitional choices and common pitfalls

• When booking counts. Before leaving, same day, or within N days. Pick one and label it.
• Patients or visits. Use unique patients so a patient seen twice is not counted twice.
• Which visit types count as hygiene. Prophylaxis, periodontal maintenance, and others. Write down the list of procedure codes or appointment types.
• Exclusions. Decide whether to exclude patients who are moving, deceased, or referred elsewhere.
• Cancelled later. A booked appointment may be cancelled the next week. The rate measures booking at the time, not attendance.

How different roles use it

Questions it answers

• What share of hygiene patients left with a next visit booked?
• Which patients need a follow-up call this week?
• Which days or providers have the lowest rate?
• Is the rate improving after a checkout change?

How to present it in a report

• A headline rate with the rule stated, such as "booked before leaving".
• A monthly trend line.
• A table by hygienist and by location.
• A linked list of unbooked patients for the front office.

Data you need

Fields

What the raw data looks like

Example data A few rows as they might come out of the source system.

Where this data usually lives

• Practice management system (PMS) holds the schedule, procedures, fees, adjustments, treatment plans, and payments. For example: Dentrix and Dentrix Ascend (Henry Schein One), Eaglesoft (Patterson Dental), Open Dental.
• Insurance clearinghouse and eligibility tools hold claims, remittances, and payer details, which explain write-offs.
• Imaging systems hold x-rays and clinical images. They are rarely needed for these metrics.
• Payroll or HR may hold hours actually worked, if the schedule does not.
• DSO data warehouses combine data from many locations, sometimes from more than one PMS.

Common data gaps and traps

• Booked time not stored. Without the appointment created time, you cannot tell booked-before-leaving from booked later.
• Recall vs appointment. A recall reminder is not a booked appointment. Make sure you count real appointments.
• Appointment types not consistent. Hygiene may be booked under several types. List them.
• Inactive patients not marked. Patients who left the practice stay in the denominator.

Related metrics

• Production per hour: a full hygiene schedule supports hygiene production.
• Case acceptance rate: treatment found in hygiene still needs to be accepted.
• Collection rate: what the practice collects of what it is owed.

FAQ

Is this the same as recall rate?

Not always. Some practices use "recall" for reminders sent. Reappointment means an appointment is actually booked.

Should I count patients or visits?

Patients. A patient seen twice in a month should count once.

What window should I use for booked later?

Pick one, such as 7 days, and label it. Show the strict rule next to it if you can.

seen        = DISTINCT patients with a completed hygiene visit in period
