Ian Wharton, founder and chief executive of Aide Health, explains why what happens between appointments matters more than what happens in clinics.
Healthcare is reaching a hard limit, not because clinicians aren’t working hard enough, but because demand is rising faster than any workforce plan can realistically keep up with.
The NHS is projected to face a workforce shortfall of 260,000-360,000 staff by 2036/37. In the US, forecasts suggest a physician shortage of up to 187,000 by 2037. These figures translate into longer waits, fewer available appointments, stretched teams, delayed diagnoses and rising pressure across primary and community care.
In response, health systems are doing what they’ve always done, trying to grow capacity, improve productivity and digitise workflows. Those efforts matter. But they won’t solve the underlying problem.
Healthcare cannot scale through appointments alone.
Most healthcare outcomes are decided outside the consulting room
Chronic disease drives the majority of healthcare demand, yet much of the system is still designed around episodic, provider-led care. For people living with long-term conditions, outcomes are shaped by what happens in daily life: medication adherence, symptom monitoring, lifestyle behaviours, confidence, understanding, and the ability to respond early when things begin to change.
This is where healthcare succeeds or fails, between the moments of formal care.
Evidence suggests over 80% of long-term condition care already takes place through self-management, yet patients are still too often treated as peripheral to the care model rather than central to it. Self-management is not an add-on. It is already how chronic care functions. The real question is whether health systems will continue to leave it unsupported or finally build around it intentionally.
Traditional healthcare delivery is fundamentally linear: more demand requires more clinician time. But clinician time is finite and becoming scarcer.
Even where staffing exists, time pressure in primary care is relentless. Guideline-based chronic care takes time per condition, per patient, per review, and with multimorbidity now commonplace, no amount of incremental efficiency improvement can close the gap indefinitely.
The result is predictable. Consultations become shorter. Education gets deprioritised. Follow-up becomes reactive. Preventable deterioration becomes acute demand. The system then absorbs those failures downstream through exacerbations, emergency admissions and higher costs.
This isn’t a reflection of clinical quality. It’s a scalability ceiling built into the model itself.
Medication adherence: The opportunity hiding in plain sight
If healthcare is serious about outcomes and efficiency, medication adherence must be treated as a strategic priority.
Across health systems, around half of patients do not take medicines as prescribed. That non-adherence drives avoidable complications and preventable hospital use, not because people don’t care, but because support often ends the moment they leave the consultation room.
It is unrealistic to expect patients to self-manage effectively after a brief appointment, with complex instructions and little reinforcement. This is exactly where supported self-management becomes essential and where digital tools can add value at scale.
Digital self-management isn’t about removing clinicians from the picture. It’s about extending care beyond the clinic and building a model that reflects how health is lived.
Done properly, digital support enables asynchronous access, so people engage when they need to, and continuous reinforcement, which supports learning and behaviour change. It has geographic reach, without relying on local capacity, and there is earlier risk identification, before problems become emergencies.
That is the scalability shift: consistent support can be delivered to more people without requiring a proportional increase in workforce.
The biggest question is whether this works in routine care. Not in pilots that disappear, but in real primary care settings with real constraints.
Patients can’t follow advice they can’t remember
A year-long partnership between Aide Health and Suffolk Primary Care, spanning seven GP practices, supported adult asthma patients through digital self-management. The results demonstrated strong engagement and measurable outcomes, including a 72% patient retention after 30 days (around 20 times the sector average) as well as a 73% medication adherence.
Digital self-management can uncover gaps that traditional care often misses, simply because services do not have the capacity to check every detail consistently between appointments.
It also protects clinical time. Education, such as inhaler technique, is critical, yet difficult to deliver reliably during short consultations. Digital tools can reinforce this education continuously, while clinicians focus on complex cases where human judgment matters most.
One of the most overlooked constraints in healthcare isn’t policy or technology, it’s memory and comprehension.
Research suggests up to 80% of medical advice is forgotten immediately, and nearly half of what is remembered is inaccurate. That creates confusion, repeated contact and avoidable harm, with a cost the NHS can’t afford.
If self-management is the backbone of sustainable healthcare, patient understanding is no longer a soft issue. It is a system requirement.
Healthcare doesn’t become sustainable by trying to push clinician capacity beyond its limits. It becomes sustainable by designing care that supports patients in the roles they already play every day.
Self-management is not second-best care. It is how care scales.
