The 8 Wastes In Lean Methodology
In yesterdays blog post (part one of this topic) we took a brief look at the role of failure demand in driving inbound calls. These calls are zero value-add even if you handle them very well. A great example of failure demand is when people don’t show up for appointments. “No Shows” or “Did Not Attends” are one point in the entire patient journey, but even this one area has the ability to return significant improvements through applying some lean principles.
Appointments occur in the “flow of time” and if they are missed they are gone forever. In lean manufacturing this loss of time might be called “muda“- a wasteful activity. Delayed appointments also shift out a whole range of resource queues and care managers have to readjust on the go leading to multiple bottlenecks and inefficiencies. Let’s take the example of a typical hospital appointment:
How Much Does A Missed Appointment Cost?
In the UK missed appointments cost around £600m ($930M) per year. In 2007/2008 around 6.8m appointments were missed and hospitals lost average revenue per appointment of circa £100.

Outpatient appointment no-shows cost hospitals £600m a year
In a detailed multi-year study conducted by VoiceSage partner HealthCom at Portsmouth Hospital Trust it was found that out of 43,000 outpatients per year Did Not Attend (DNA’s) ran to 3,300 and through a combination of missed appointments, lost capacity, and lost or delayed, cost them £4m ($6.1m) annually.

What you will notice from these results is that interventions to control variation at the root cause surfaces dramatic improvements in cost outcomes. A planned, automated and pro-active communications strategy that reaches out to patients at the right time, with the right message and re-communicates their appointment details, or attempts to reconfirm their intention to attend, removes some of the variation in attendance.

Why Do People Miss Their Appointments?
We know that missed appointments happen but if they are so important to everyone, why do they happen and why did proactive communications make a difference?
A 2005 Study of General Practice Doctors Appointments in the UK cited the reason of ” I simply forgot” by 40% of respondents, and “rescheduling difficulty” (i.e. tried to cancel but could not/ appointment was at an inconvenient time) by 20% of respondents. These, coupled with practice specific factors were significant drivers of missed appointments. In general the younger you are, and the more socially disadvantaged your background, the more likely you are to miss an appointment.
Although there are a number of studies into appointment keeping, a 2004 Study cited three main drivers as to why people missed appointments without notifying the clinic staff:
- Emotions – Fear and anxiety about procedures or of getting bad news
- Disrespect – Patients feel that the system/ provider does not respect them
- Understanding – Did not understand the scheduling system itself
Rather than leave these drivers unaddressed a decent case can be made for looking at the actions, behaviors and processes that propagate them.
- In the case of Emotion of Fear cited above how much more care could be taken around all the communications which we send to patients?
- If we send letters could we take more care with the language used?
- Could we follow up the letter with a simple phone call to give assurance?
- Could we better match patient and customer care staff to encourage communications with nervous patients?
Many sectors that VoiceSage is working with have realised significant improvements through personalising messages and tailoring them to customer types or personae and matching these to each stage on the customer-patient journey. This is where the power of flexibility and iteration shows up clearly in results and outcomes.
2. To take the second point for Mutual Respect, proactively reminding people might be seen to show you care about the appointment and that it happens. It creates a sense of being in a managed process, that you are being cared for, and progressed.
However this should be seen in the wider context that when a person shows up for an appointment that they are seen to within a reasonable amount of time. When you do not account for the financial and social costs to the patient of being in a long queue at the clinic you run the risk of being seen to disrespect the value of their time and them as individuals. It stands to reason that just getting someone to keep their initial appointment time and then keep them waiting does not encourage them to show up on time next time. Indeed it’s likely that they will tell others not to worry about arriving on time. This would be a classic example of where you get one point in the process right, only to have it’s beneficial effects dissipated elsewhere.
This “disrespect factor” showed up strongly in a recent “Cost of Waiting Report” produced by TOA Technologies with regards why such long waiting windows were experienced in general appointments and deliveries. In general when dealing with larger companies and organisations many people find that their time isn’t being respected.

Of course waiting times at the clinic are not the only driver of feelings of disrespect. Overall levels of patient care and quality of overall interaction will also drive “Did Not Attends” that have their source in this feeling of disrespect. Perhaps this is one reason why the Care Quality Commission uses these missed appointment measures as a proxy measure for overall Quality of Care evaluations, particularly in the interface with community based care and the quality of the referrals process. I should give an absolutely shameless plug to the VoiceSage Survey product here because this is an ideal example of where you can conduct a post-interaction survey to gather a Net Promoter Score (NPS) measure and tie it back to specific factors underpinning that opinion (VoiceSage won European Call Center and Customer Service Product of the Year 2011 for this).
3. Not Understanding The Scheduling System – while I expect that much user experience of computer and online systems have improved over the last few years there are still gains to be made from addressing the usability of systems. By giving patients simple interfaces online, and clear plain language communications via SMS and Interactive Voice you can present patients with clear choices and clear actions. Although it is expected that smartphones will account for nearly 10% of all phones in the very near future, higher level impacts can still be attained today through simple, well thought out communications strategies that use SMS and simple Voice Interfaces.
The Point Of Interaction In The Patient Journey
Missed appointments can be mitigated by deploying proactive contact strategies that are simple, thoughtful, and caring. People do forget to make arrangements so that they can make agreed appointment times. People do get frightened and avoid going to the appointment. People don’t always feel they are respected by their service providers in healthcare and in other sectors. As we have seen above reducing missed appointments has meaningful cost implications. What I think is worth exploring further is how these appointment confirmation events tie into a more holistic appointment experience measure and how in turn these show up in overall customer care and quality of service evaluations.
