Not every inbound call to your clinical research site belongs with the same person. A patient inquiry about eligibility needs a research coordinator. A physician asking about referral procedures needs a different conversation. A sponsor representative needs your PI or site manager. A current participant with a safety concern needs immediate clinical attention. When all of these calls route to the same number and the same voicemail, clinical priority is lost, response time is inconsistent, and staff time is misallocated. Call triage — routing inbound calls based on caller type and need — is the infrastructure that fixes this.
The Four Caller Types and Their Correct Routing
- Patient inquiries (new): Route to research coordinator or AI assistant during business hours. After hours: AI assistant or auto-SMS with callback commitment. Priority: high. Target response: same business day.
- Current participant calls: Route to designated study coordinator by name, not general voicemail. Participants need to reach a person they know. If unavailable, voicemail routes to coordinator’s mobile for monitoring. Priority: high for safety concerns, standard for logistics. Target response: 4 hours for any mention of symptoms or concerns.
- Physician referrals: Route to site manager or PI. These are relationship calls, not administrative ones. A physician who refers a patient and gets transferred to a coordinator voicemail will not refer again. Priority: high. Target response: same day.
- Sponsor or CRO contacts: Route to PI or site director. Never to a coordinator who may not have the context to respond appropriately. Priority: standard. Target response: one business day.
Implementing Triage Without an AI System
A simple IVR (Interactive Voice Response) menu handles basic routing without AI. Most VoIP platforms include IVR in standard plans:
“Thank you for calling [site name]. For information about joining a clinical trial, press 1. If you are a current study participant, press 2. For physician referrals, press 3. For all other inquiries, press 4.”
Each option routes to the appropriate extension or voicemail group. This basic routing ensures caller type determines response priority without requiring AI.
The Safety Escalation Protocol
Every call routing system must have a safety override: any caller who mentions feeling unwell, a reaction to study medication, or a health emergency must be able to reach a clinical staff member immediately — not a menu, not voicemail. In your IVR design, this means: (1) the menu always includes an option for urgent participant concerns that routes directly to a clinical staff member’s direct line or on-call number, and (2) your AI assistant is trained to escalate immediately when safety-related language is detected, bypassing all other flows.
Tracking Routing Effectiveness
Monthly: pull your call log and categorize calls by routing path taken. Calculate: what percentage of patient inquiry calls reached a live coordinator within one business day? What percentage of participant safety calls were answered by a clinical staff member within one hour? These are the two metrics that determine whether your routing is working. Both should be at 90%+ for a well-functioning triage system.
48-Hour Action List
- Hour 1: Map your four caller types and write the routing destination for each. Identify which currently routes incorrectly or to the wrong person.
- Hour 2: Log into your VoIP platform and configure an IVR menu using the four-option structure above. Set routing rules for each option: call group, extension, or voicemail box.
- Hour 3: Record the IVR menu greeting using the template above, customized for your site. Test all four options by calling from outside the office.
- Day 2: Communicate the new routing system to current participants — they need to know to press 2 for participant calls. Update your website’s contact page to reflect the menu options. Set a 30-day review to check routing performance using call log data.
