Challenges
Documentation overload
As a GP Partner managing both telephone and face-to-face consultations, Dr. Rajah found documentation to be a significant drain on her time and energy. The laborious task of capturing patient information after each consultation was exhausting and took away from valuable patient time.
“As a GP we all know that taking a detailed history and really listening to the patient's concerns would mean we have to spend a significant amount of time after documenting. We often find we briefen our notes to catch up on time but in regards to the medical-legal aspect of our work, we are not doing ourselves any favours by doing this.
“Functional medicine involves in-depth history-taking, from birth history to lifestyle patterns."
Cognitive load and clinician fatigue
Dr. Rajah’s research into cognitive load highlighted a key issue in clinical practice: excessive mental effort required for multi-tasking during consultations. GPs must listen, process, document, and maintain rapport with patients, which often sadly but understandably can lead to burnout.
“For me, the extraneous load was having to input lots of different bits of data, like the letters, the pathology results... and at the same time in addition to responding to the receptionist knocking on my door, calling me on the phone etc."
Balancing efficiency with personalised care
Dr. Rajah wanted to improve efficiency without losing the personal touch in patient interactions. She struggled with how to maintain a high level of patient engagement while managing administrative tasks.
"I didn’t want to sacrifice patient rapport for efficiency. Heidi has helped me do both – be efficient without losing the personal connection with my patients."
Solution
Dr. Rajah adopted Heidi Health to streamline documentation, reduce cognitive load, and improve patient interactions. The transition was seamless, requiring minimal setup.
"What I really liked was how simple it was to start using Heidi. No software downloads, no long registration process - just log in, and you're ready to go."

Antecedents:John has a history of anxiety and mild depression…
Triggering Events:Symptoms worsened after a high-stress period…
Defense & Repair:Likely ongoing gut inflammation due to food sensitivities and stress. Possible immune dysfunction linked to gut dysbiosis.
Time savings and efficiency gains
With Heidi, Dr. Rajah has more time and energy to focus on other clinical responsibilities, while maintaining fulfilling patient-facing interactions.
"I immediately saw how accurately Heidi recorded what I was saying, which made a huge difference. I didn’t have to spend extra time writing up notes after each consultation."
"As a partner, I finish my workload quicker, which lets me focus on managing the practice, handling staff issues, and making strategic improvements."
Standardisation and team adoption
Although some colleagues were initially hesitant, Heidi’s customisable templates helped address concerns about note readability and consistency.
"The resistance to AI is a personal choice, but those who embrace efficiency will see the benefits. Heidi-generated notes can be customised to match individual preferences."
What’s next
“With the issue of burnout being a real problem, I do believe it is important to consider AI solutions to help improve the enjoyment and retention within our profession. Also really most importantly it gives us time to spend on our families/friends and ourselves. I love that it is going to give me time to pursue my functional practice, while still being a very invested NHS GP partner.”
