A patient’s experience of physiotherapy is shaped by more than the time spent with a clinician. It also includes the wait for triage, the search for a suitable appointment, gaps between sessions, cancellations and the time it takes for discharge information to reach the referrer.
Value stream mapping (VSM) makes that whole journey visible. Instead of improving one appointment or department in isolation, a clinic maps how patients, information and clinical work move from first contact to a completed episode of care. The result is a shared, evidence-based view of delays, rework and capacity, and a practical basis for redesign.
The worked example below uses illustrative clinic data, not a benchmark. Actual performance will depend on case mix, staffing, access needs and clinical protocols.
1. Choose a clear patient-centred scope
Select a product family with a recognisable pathway. Here, it is a musculoskeletal rehabilitation episode of care.
Set the boundaries from referral or first enquiry received to discharge completed and the outcome measure recorded. Include scheduling and cancellation handling, not just face-to-face treatment. This scope is useful because it connects access, continuity, clinician capacity and communication with the referrer.
Before mapping, agree on:
- Which patients and referral sources are included.
- What counts as a completed episode.
- How cancellations and did-not-attend appointments are defined.
- Whether lead time is measured in calendar days or working days.
- What patient outcomes and balancing measures must be protected.
For help defining a manageable improvement project, see our guide to scoping Lean Six Sigma projects.
2. Map the current state with real observations
Follow the process as it operates today. Observe work, ask patients and staff about handoffs, and sample enough episodes to capture variation. Record both touch time, active work, and waiting time between activities.
The sample below assumes a clinic receiving 30 new musculoskeletal referrals per week. An episode averages six appointments: one first assessment and five subsequent treatment sessions.
| Current-state step | Active touch time per episode | Waiting time on the pathway |
|---|---|---|
| Referral triage and completeness check | 10 min | 2 days |
| Appointment scheduling and confirmation | 8 min | 10 days |
| First assessment | 45 min | 0 days |
| Treatment plan documentation | 15 min | 3 days to next session |
| Five treatment sessions | 5 × 30 = 150 min | 35 days between sessions |
| Home exercise program (HEP) preparation and explanation | 12 min | 0 days |
| Outcome re-measurement | 20 min | 3 days |
| Discharge and report to referrer | 10 min | 3 days |
| Total | 270 min | 56 days |
The 12-day wait before the first appointment is the 2-day triage queue plus 10 days to find and confirm a slot. The total episode lead time is approximately 56 calendar days from referral to discharge report. Since some work occurs during appointments, the waiting intervals are rounded pathway estimates rather than a claim that every episode follows an identical sequence.
Of the 270 active minutes, assume 242 minutes directly contribute to assessment, treatment, self-management or outcome evaluation. The remaining 28 minutes are administrative activity. On that basis:
- Value-added share of touch time: 242 ÷ 270 = 89.6%.
- Process cycle efficiency (PCE): 242 minutes ÷ 80,640 elapsed minutes = 0.30%.
PCE compares value-adding time with total elapsed lead time, using the same units. The small result highlights how much of a patient’s calendar journey is waiting. It does not mean the clinical work itself is inefficient. You can review the process cycle efficiency calculator.
Include access, cancellations and capacity measures
For this example, suppose the clinic records a 12% missed-appointment rate across scheduled visits: 8% cancelled appointments and 4% did-not-attend (DNA). Only 25% of cancelled slots are filled from a backfill list. The clinic also measures 68% room utilisation, 72% on-time starts, and an average of 42 minutes of clinician documentation after hours per week.
For a simple takt-time check, assume the clinic has 7,200 staffed treatment minutes available per week and demand for 216 appointments. The appointment rhythm required to meet demand is:
Takt time = available treatment minutes ÷ weekly appointment demand
7,200 ÷ 216 = 33.3 minutes per appointment
This is an average planning rhythm, not a substitute for appropriate appointment lengths. Assessment and follow-up slots may need different durations.
3. Find waste without losing sight of patient value
Use DOWNTIME to prompt observation. The aim is to remove friction while maintaining safe, appropriate care.
- Defects: Incomplete referral documentation triggers follow-up calls, re-triage or booking delays.
- Overproduction: Reports, forms or instructions are prepared before they are needed or used.
- Waiting: Patients wait for a first slot or the next session; clinicians can have idle time when cancellations are not backfilled.
- Non-utilised talent: Therapists spend valuable clinical time handling routine booking administration.
- Transportation: Paper forms or records move between reception, treatment rooms and clinical teams.
- Inventory: A backlog of untriaged referrals or unfinished discharge reports accumulates.
- Motion: Staff move between shared rooms to locate equipment or reset spaces between patients.
- Extra processing: Administrative notes are duplicated across booking and clinical systems.
Distinguish between a cancellation and a DNA in the data. A cancellation may provide time to offer a slot to another patient; a DNA usually leaves the appointment unused unless the clinic can respond quickly. Track both rates and the slot recovery rate.
The issue has practical consequences. An Australian costing study reported physiotherapy non-attendance rates of 8% and 10% at two tertiary outpatient clinics and estimated substantial staff-cost impacts at one clinic. Those figures are specific to the services studied, but they underline why missed appointments belong on the map, not just in a monthly attendance report. Read the study.
4. Design a future state around reliable flow
The future-state map should make the next step clear for patients and staff. A clinic might test the following changes:
- Use tiered triage. Apply agreed criteria to prioritise clinical urgency, identify missing referral information early, and route suitable cases to the right service.
- Standardise assessment templates. Capture essential history, baseline measures, treatment decisions and follow-up requirements without creating unnecessary documentation.
- Design appointment slots deliberately. Match duration and format to clinical need, and protect appropriate capacity for new assessments and follow-ups.
- Build a cancellation backfill process. Maintain a consent-based wait-list, record preferred times, and offer released appointments promptly.
- Offer suitable care formats. Where clinically appropriate and accessible, consider group or telehealth streams. These should be clinician-led choices, not default substitutions.
- Capture outcomes across the episode. Record relevant measures at assessment, during treatment and at re-measurement, so progress informs care and discharge.
- Close the loop at discharge. Set a clear owner and turnaround target for the outcome record and report to the referrer.
Appointment reminders can support attendance, but they are only one part of the system. Research reviews note that reminders can also help patients cancel or reschedule in time for a service to reallocate a slot. Pair them with easy response options and a functioning backfill process. Review of appointment reminder systems.
Current state versus a 90-day future-state target
The targets below are proposed pilot goals for the illustrative clinic. Validate them against baseline data, clinical needs and patient experience before adoption.
| Measure | Current | 90-day target |
|---|---|---|
| Lead time to first appointment | 12 days | 5 days |
| Total episode duration | 56 days | 35 days |
| Process cycle efficiency | 0.30% | 0.48% |
| Did-not-attend rate | 4% | 2% |
| Average sessions per episode | 6.0 | 5.7, where clinically appropriate |
| Room utilisation | 68% | 78% |
| On-time starts | 72% | 90% |
| Clinician documentation after hours | 42 min/week | 15 min/week |
A lower average number of sessions is not inherently better. Interpret it alongside outcome measures, patient goals, discharge reasons and re-referral rates. Efficiency gains must not come at the expense of appropriate care or equitable access.
5. Sequence improvement through 90-day kaizen waves
Use short improvement cycles, assign owners and review both results and balancing measures.
| Wave | Priority actions | Suggested owner | Measures |
|---|---|---|---|
| Days 1–30: establish and test | Confirm definitions; observe the pathway; standardise referral completeness checks; trial a cancellation reason code and backfill list. | Clinic manager and senior physiotherapist | Baseline access, cancellations and DNA; slot recovery; referral rework |
| Days 31–60: redesign booking flow | Pilot tiered triage, slot templates, response-enabled reminders and a daily review of unfilled appointments. | Booking lead and triage clinician | First-appointment lead time; recovered slots; on-time starts; staff workload |
| Days 61–90: stabilise and extend | Test suitable group or telehealth pathways; standardise outcome capture and discharge reporting; audit the revised process. | Clinical lead and quality improvement lead | Episode duration, outcomes, room utilisation, after-hours documentation and patient feedback |
Review performance weekly with a simple visual management board. Segment results where appropriate (for example by referral source, appointment type or access needs) so an overall improvement does not conceal barriers for a particular patient group.
Turn the map into measurable improvement
The strength of value stream mapping is its whole-pathway view: it connects referral quality, booking decisions, clinical work, cancellations and discharge into one patient-centred system. A current-state map shows where time is spent; a future-state map makes the desired flow explicit; kaizen tests whether the changes work in practice.
