Improving healthcare access with an optimised referral process

Context

Tan Tock Seng Hospital is one of the largest hospitals in Singapore. The hospital works closely with primary and community care partners to provide quality health care services to the population.

Challenge

Receiving thousands of referral from General Practitioners every month, the hospital struggled to process these referrals efficiently, leading to delays in patient treatment:

  • Physical referral forms are easily misplaced

  • General Practitioners were not providing enough patient details

  • Lack of visibility into the referral flow

Starting off with a design brief

To start every one off on the right track, I created a design brief that documents the initial assumptions, hard facts, goals and relevant information about this project.

Interviewing users

To understand the existing process and challenges faced by each user group, we interviewed over 25 users, including General Practitioners, Clinic Assistants, Call Centre Operators, Patient Service Associates and Specialists.


I created a stakeholder interview plan documenting the research goals for each user group and planned the questions accordingly.

Insights from the interviews

General Practitioners & Clinic Assistants:

01

Lack visibility into the referral process to respond to patients

02

Lacks information on patient diagnosis for follow-up

03

Finds it difficult to liaise on patient appointment via calls and fax

Call Centre Operators:

01

Frequent of back and forth due to incorrect referral form filling

02

Needs an easy way to organise referrals by urgency

03

Difficult to reschedule appointments as ideal time is unclear

Specialists & Assistants

01

Concerns over incorrect appointment scheduling by Call Centre

02

Form requirements differ significantly across specialist clinics

03

Insufficient patient details provided by General Practitioners

Empathising with users

To better empathise with users, we crafted personas of our target audience and created journey maps to visualise the process that users go through to accomplish their goals.

Understanding the referral process

From the interviews, we realised that the referral workflow is a complex process involving many different parties. To visualise the existing process and identify opportunities for improvement, we created a few process flows detailing the series of steps users will take to complete a referral.

Framing the challenge

Next, we proceeded to frame HMW statements to help us focus on the right problems to solve.

How might we…

Help GPs create referrals with the correct information?

Help users schedule patient appointments efficiently?

Help users follow-up on referrals on time?

Brainstorming, Dot Voting & Crazy 8’s

We held a brainstorming session where participants were given time to generate as many ideas as they could, focusing on quantity instead of quality.


To further encourage idea generation, we did a Crazy 8’s exercise where participants are given 8 minutes to sketch 8 ideas each.

Prototyping & validating solution

After understanding the problem space, we proceeded to design the high fidelity mockups and conduct usability testing on them. We conducted 1-1 usability testings with over 20 users from 5 different user groups.

Insights from the usability testing sessions

General Practitioners & Clinic Assistants:

01

Too many mandatory fields, GPs may lack required information

02

Referral status is helpful, but status description can be clearer

03

Tendency to assign referrals as fast track for faster appointments.

Call Centre Operators:

01

To avoid double work, needs to identify who is handling the referrals

02

Status description should be similar to the terms they are using

03

Needs an option to send routine referrals for triaging

Specialists & Assistants

01

Requires clearer indication on when the referral is created

02

Recommended appointment period is very useful

03

Needs a way to edit or cancel appointment if patient does not attend

The final solution

For General Practitioners & Clinic Assistants

A step by step referral creation flow that guides General Practitioners on the correct information to provide while minimising the amount of data entry with auto fill.

For Contact Centre Operators

Clear prioritisation of task load with the flexibility to send referrals for triaging. With Specialists’ indications of suggested appointment period, Contact Centre Operators can schedule appointments more accurately.

For Specialists & Assistants

A streamlined process of updating patient attendance and medical records. General Practitioners are kept updated automatically without the need for back and forth emails.

For System Administrators

Track and manage all referrals, view vital statistics and customise forms to meet department-specific form requirements.

Outcomes and learnings

The successful launch of the pilot project has connected over 30 clinics to 5 specialist departments at Tan Tock Seng Hospital. With the success of the pilot, the National Health Group has awarded Accredify to proceed with the next phase of the project.


A key lesson I’ve learned is the importance of starting a user roles permission matrix early. With several user roles and differing permissions, the matrix will not only assist designers in screen designs, but also facilitate a smoother handover to developers.


Overall, I am happy that the platform we’ve designed bridged the gaps between the users and facilitated the flow of crucial information to minimise delays in patient treatment.
