The Challenge

What the hospital was dealing with

Aegis Healthcare operated entirely through a 12-seat call centre for all patient appointment management. During peak morning hours, call abandonment rates reached 28% — meaning nearly 1 in 3 patients gave up and potentially sought care elsewhere.

Patients who needed lab reports had to physically visit the clinic counter to request a print-out. Prescriptions were on paper only. There was no digital record patients could access independently, creating dependency on staff for every interaction and leading to repeated follow-up calls that clogged the call queue further.

The management team wanted a branded digital presence that matched their clinical reputation — not a generic third-party aggregator that sent patients to competitors.

The Solution

How Goolk AI approached it

Goolk AI built a fully white-labeled patient app for iOS and Android — branded entirely under the Aegis Healthcare identity, with no third-party booking platform branding.

Booking & Scheduling: Patients view real-time doctor availability calendars, book by specialty, and pay via UPI or card. Auto-confirmation is sent via push notification, SMS, and WhatsApp simultaneously.

Digital Records: The app connects via secure APIs to the hospital's EMR. Lab reports are pushed to patient profiles the moment the laboratory releases them. E-prescriptions are auto-converted to signed PDFs and delivered through the app.

AI Triage Assist: A lightweight symptom-checking flow guides patients to the appropriate specialty before booking — reducing misdirected appointments by 18%.

Re-engagement Engine: Automated follow-up workflows remind patients about upcoming appointments, medication schedules, and health checkup due-dates — reducing no-shows by 32%.

The Outcomes

Measured results at 90 days

Within 90 days of launch, online booking volume increased by 85%. Inbound call centre volume dropped 40%, freeing staff to handle complex clinical queries.

78% of patients discharged from the hospital registered on the app within 24 hours of receiving the QR code at the billing counter. The app earned a 4.8-star rating on iOS App Store and 4.7 on Google Play within the first three months.

The hospital chain reported a measurable improvement in patient retention, with returning patients booking digitally at a 91% rate after their first app appointment.
