My role in the project
Inspired by the Leeds PROMPTS trial
I took the lead in formulating and developing the idea, data collection, data analysis, writing up and publication
Research was conducted on my special interest day during my ST4 post

Background
Out-patient clinics- an important contactFailed attendance adds to the cost of careAdverse impact – missing medicationsDelay in identifying relapsesIncreases waiting time for othersIt costed NHS 360 million pounds in 1997? > 0.5 billion per year now
![Page 4: Does Prompting Reduce DNA Rates: BIPA Prize Presentation](https://reader036.fdocuments.us/reader036/viewer/2022062514/558a3158d8b42a2c138b45fd/html5/thumbnails/4.jpg)
Causes of non-attendance?
Conscious decision (benefits vs risk)
Often have a treatable morbidity
Commonest – forgetting the appointment
Forgetting – medication non-adherence
Unrelated to severity (other specialities)
Severe mental illness – more likely

Implications of non-attendance
Delay in identifying EWS of relapse Disengagement from services Trust performance indicator- CQC reportBanded on a scale of 1 to 5 (high=better)Rate < 11% considered acceptableFinancial penalties for high DNA rates?

Evidence for prompting
Leeds PROMPTS trial (N 764, RR 0.76, CI 0.59 to 0.98,NNT 16, 95% CI 10 to 187)
- Psychological Medicine 2008
Systematic review (serious mental illness)5RCTs, N 1184, RR 0.72, CI 0.59 to
0.89, NNT 6, CI 4 to 14 - Cochrane 2001 + PROMPTS Trial

Aim
To implement this evidence based intervention of sending prompt letters in our out-patient clinics in the pragmatic real world non-randomised setting & measure the non-attendance rate.
(Prompting works in trial settings but does it work in the real world?)
![Page 8: Does Prompting Reduce DNA Rates: BIPA Prize Presentation](https://reader036.fdocuments.us/reader036/viewer/2022062514/558a3158d8b42a2c138b45fd/html5/thumbnails/8.jpg)
Methods
Prompting letter to all patients attending outpatient clinic in South Leeds (2 CMHT)
Letter sent one week before appointment
Royal mail First Class Post
Ongoing practice since June 2007
DNA- failed to attend & no message
![Page 9: Does Prompting Reduce DNA Rates: BIPA Prize Presentation](https://reader036.fdocuments.us/reader036/viewer/2022062514/558a3158d8b42a2c138b45fd/html5/thumbnails/9.jpg)
Dear [Patient’s name]
Re: Your appointment at Bridge House
This is a short reminder of your appointment at Bridge House on the [Date at Time]. Your appointment will be with Dr. XX and will last for xx minutes. This interview will be private and confidential. It is often helpful if you bring a friend or family member and medications along. Our clinic has a reception and once the receptionist knows you have arrived, she will inform the doctor.
Bridge House is located on Balm Road and a map with directions is enclosed with this letter.
If you have forgotten about the appointment or made other plans, do not worry. Please let me know at the above telephone number and we will rearrange your appointment at a time which is convenient for you.
[Name of Secretary]

Data analysis
Compared DNA rates before and after this intervention in 2007
Compared with DNA rates in the same months in 2006 (seasonal variation)
Trend across the whole year
Compared with DNA rates in West Leeds where no prompting was used

Results
June – Nov 07 June-Nov 06 Jan-May 07
17% 27% 26%
A total of 1433 letters were sent out in the study period.
Average non-attendance rates across different periods

Comparison with West Leeds

So a reduction in the DNA rate in our study is unlikely to bedue to a general reduction across the city!
Average non-attendance rates

Were samples comparable?
1433 appointments575 patients (2007)
90% patients sameas in 2006
10% patients new to 2007
So a reduction in the DNA rate in our study is unlikely to bedue to a having a different set of patients in 2007!
![Page 16: Does Prompting Reduce DNA Rates: BIPA Prize Presentation](https://reader036.fdocuments.us/reader036/viewer/2022062514/558a3158d8b42a2c138b45fd/html5/thumbnails/16.jpg)
Were the clinicians different?
Clinicians in 2007 may have acted differently toward patients compared to 06
Yes!
- one Consultant changed in Mar 2007
- SHOs, SpRs & Staff Grade changed
Drawback of pragmatic studies in NHS!
![Page 17: Does Prompting Reduce DNA Rates: BIPA Prize Presentation](https://reader036.fdocuments.us/reader036/viewer/2022062514/558a3158d8b42a2c138b45fd/html5/thumbnails/17.jpg)
Patients getting better over time?
New for 2007
Remained constant
RR 95% CI
15% 17% 1.17 0.79 to 1.74
Average non-attendance rates
So a reduction in the DNA rate in our study is unlikely to bedue to an improvement in their mental state!

Conclusion
Prompting letters do reduce non-attendance rates even under non-trial conditions
Useful and easy to apply intervention with no implication on resources
£80 saved for every £3 spent (NNT 11)!!
(reference cost of each appointment - £80)
