A patient calls your clinic. The phone rings six times. No one picks up. She tries the clinic two doors down. You never knew she called. That call is gone — and so is the booking.
Multiply by a week. Then a month. The number gets ugly fast.
What this post covers
- The four ways calls leak out of a Singapore clinic.
- A real-world math walk-through for one clinic.
- What "good" looks like and how to measure your own.
A typical day at a Singapore primary care clinic
A solo GP in Toa Payoh runs about 40 to 80 inbound calls a day. A two-doctor practice runs 100 to 160. A small group with three or four doctors runs 200 plus. These are rough ranges from clinic interviews; your number will sit somewhere on the curve depending on specialty and patient panel size.
Your front desk handles those calls between greeting walk-ins, taking payments, filing claims, chasing the lab, and answering WhatsApp. The phone is one job among ten. Drops are inevitable.
The four leak points
Every missed call falls into one of four buckets. Most clinic owners can only see the first one — and only partially.
1. Rings unanswered
The phone rings. The receptionist is on another line, with a walk-in, or in the back room. The call rings out. Most modern phone systems log this. Few owners check the log.
2. Busy signal
You have one line. Someone is already on it. The new caller hears a busy tone and hangs up. Your phone system probably does not log this at all. It is invisible.
3. After-hours
The clinic closes at 6 pm. Calls after that go to voicemail or nowhere. A few patients leave a message. Most do not. They call the next clinic on the Google search.
4. Hold abandons
The receptionist picks up, asks the caller to hold, then gets pulled away. The caller waits 30 seconds, hangs up. This shows in the log as "answered" — which is technically true. The booking still did not happen.
How big is the leak, really?
Industry benchmarks for healthcare call abandonment sit between 8% and 25%. Singapore primary care anecdotally runs at 15% or higher. That is the share of inbound calls where the caller hangs up before booking.
We can put a S$ figure on it. The math has three steps.
- Estimate inbound call volume. Count attempted calls, not picked-up calls.
- Apply the abandonment rate. What share never connect or never book.
- Multiply by expected revenue per missed booking.
That last number — expected revenue per missed call — is the one most owners over-think. Not every missed call would have booked. A reasonable rule of thumb from our pilot data is that about 60% of missed calls would have led to a booking. The other 40% are duplicate calls, pharmacy queries, wrong numbers, or window-shoppers.
So the formula is:
monthly leak (S$) = monthly missed calls × 0.6 × average first-visit fee
A walked-through example
Let us run the numbers on a hypothetical Bedok GP. Two doctors. 6 days a week. 32 consults per doctor per day. First-visit fee S$60. Missed-call rate guessed at 20%.
| Step | Value |
|---|---|
| Weekly consult capacity (2 × 32 × 6) | 384 |
| Monthly consult capacity (× 4.33 weeks) | about 1,663 |
| Monthly inbound calls (capacity ÷ 0.8) | about 2,079 |
| Missed calls per month (20% of inbound) | about 416 |
| Bookings lost (60% of missed) | about 250 |
| Lost revenue (250 × S$60) | S$15,000 |
| Annualised | S$180,000 |
S$15,000 a month. S$180,000 a year. For a two-doctor clinic. From the phone alone — before counting no-shows, recall failures, or referral drop-offs.
Why the leak is invisible
Three reasons clinic owners under-count this.
- Phone systems log connections, not attempts. The 20% who never connected do not appear in any report.
- Patients do not complain. A caller who hangs up just calls the next clinic. There is no angry message in your inbox.
- The front desk does not feel busy "enough". A receptionist handling 50 picked-up calls a day feels productive. The 10 calls that did not connect are not on her radar — she never knew they happened.
The leak is silent. The revenue is gone before you have a chance to recover it.
What "good" looks like
Numbers to aim for, based on our Founding 5 pilot:
- Call answer rate above 95%, including after-hours and weekend calls.
- Pickup before the third ring, every shift.
- Hold abandons below 2%.
- First-call resolution above 80% — patient books on the first call, no callback needed.
Most clinics start at 75% to 85% answer rate during business hours and zero overnight. Closing the gap typically recovers 10% to 20% of monthly revenue.
Count your own leak in 5 minutes
You do not need to build a spreadsheet. The free Revenue Recovery Report walks you through ten fields and emails you a PDF with your monthly leak figure in S$ on the cover. It uses the same formula above and the same 60% bookings-per-missed-call assumption.
The math is on our methodology page. The numbers it returns are yours, not ours.
What to do this week
You do not need to buy anything to start. Three actions you can take on Monday:
- Pull last week's missed-call log from your phone system. Note the total.
- Ask your receptionist for her gut feel on after-hours and weekend call attempts. Add a conservative 30% to the logged number.
- Multiply the total by 0.6 and by your first-visit fee. That is your weekly leak. Times 4 is your monthly leak.
If the number is bigger than you can stomach, you have two choices: hire another receptionist, or close the gap with a co-pilot. Either way, you now know the size of the problem.
