In pharmaceutical strategy, KOL engagement is often viewed as a familiar playbook.
Identify the leading experts.
Build relationships.
Drive scientific advocacy and education.
Globally, the framework appears consistent.
But across Southeast Asia, KOL influence does not operate in a uniform way.
And that is where many organisations get it wrong.
Because in this region:
Influence is shaped as much by local dynamics as by scientific credibility.
The Assumption: KOL Strategies Are Transferable
One of the most common assumptions I’ve observed is that a successful KOL strategy in one market can be replicated across the region.
The logic seems reasonable:
- Science is global
- Clinical evidence is universal
- Expert influence should therefore behave similarly
But Southeast Asia is not a homogeneous market.
Healthcare systems differ.
Institutional structures differ.
Cultural dynamics differ.
And as a result:
KOL influence differs significantly from market to market.
The Reality: Influence Is Highly Localised
In some markets, influence is driven heavily by:
- Institutional positions
- Academic standing
- Publication history
In others:
- Relationships
- Local networks
- Hospital affiliations
- Peer influence
play an equally important role.
This means that identifying KOLs is only the first step.
The more important question is:
How does influence actually flow within that market?
Country Comparison: Singapore vs Thailand vs Vietnam vs Indonesia
To illustrate how KOL influence differs across Southeast Asia, consider four very different markets.
Singapore: Evidence and Institutional Credibility
Singapore’s healthcare system is highly structured and globally connected.
KOL influence is often driven by:
- Academic credibility
- Research involvement
- International exposure
- Institutional leadership positions
Healthcare professionals tend to place strong emphasis on:
- Clinical evidence
- Global treatment standards
- Scientific rigor
- Institutional leadership positions
Implication:
KOL engagement in Singapore is highly science-driven and intellectually rigorous.
Global experts and international congress visibility carry significant influence.
Thailand: Networks, Institutional Influence, and Therapeutic Community Reputation
Thailand presents a different dynamic.
While scientific credibility remains important, influence is also shaped by:
- Institutional relationships
- Seniority within hospital systems
- Professional society involvement
- Local referral and training networks
In therapeutic areas such as:
- Oncology
- Infectious diseases
- Cardiology
- Diabetes and metabolic disease
local and regional reputation within specialist communities can sometimes carry more practical influence than international visibility alone.
This is particularly important in large teaching hospitals and public healthcare institutions where referral networks and professional relationships remain highly influential.
Implication:
Engagement strategies must account not only for scientific leadership, but also for institutional and specialty-network influence structures.
Vietnam: Institutional Hierarchy and Key Center Influence
Vietnam’s healthcare environment is evolving rapidly, but remains highly institution-centric.
KOL influence is often concentrated around:
- Major central hospitals
- Leading academic institutions
- Senior department heads
- Government-linked medical networks
In many therapeutic areas:
- Oncology
- Vaccines
- Anti-infectives
- Specialty care
physician influence tends to flow strongly from leading national institutions into provincial practice.
Hierarchy and institutional standing remain highly important.
At the same time, practical clinical applicability and accessibility of treatment approaches are critical factors in physician adoption.
Implication:
Successful KOL engagement in Vietnam often requires:
- Strong institutional engagement
- Respect for hierarchy
- Long-term relationship development with key national centers
Indonesia: Relationships and Local Trust
Indonesia is even more relationship-driven.
The healthcare landscape is large and decentralised, with significant variability across regions.
KOL influence is often shaped by:
- Long-standing local relationships
- Regional professional networks
- Trust built through repeated engagement
- Practical relevance to local clinical realities
In many cases, accessibility and trust matter as much as academic stature.
Implication:
Effective KOL engagement requires sustained local presence and deeper relationship-building.
The Real Insight
The difference is not simply about identifying different experts.
It is about understanding:
- What creates credibility
- How influence spreads
- What healthcare professionals value locally
Singapore is largely evidence- and institution-driven.
Thailand is network- and specialty-community influenced.
Vietnam is hierarchy- and institution-driven.
Indonesia is relationship- and trust-driven.
And that fundamentally changes how KOL strategies should be designed.
The Mistake of Over-Reliance on Regional KOLs
Another common challenge is over-reliance on regional or international KOLs.
Regional experts are important.
They:
- Build scientific credibility
- Elevate regional visibility
- Support strategic positioning
But regional influence does not automatically translate into local adoption.
In many Southeast Asian markets:
Local KOLs often drive practical behaviour change more effectively than regional experts.
This is especially true when:
- Treatment practices differ
- Access realities vary
- Resource constraints exist
- Clinical workflows are highly localised
KOL Engagement Is Not Just About Events
Another misconception is that KOL engagement is primarily event-driven.
Congress participation.
Speaker programs.
Advisory boards.
These remain important.
But increasingly, effective KOL engagement requires:
- Continuous scientific dialogue
- Real-world collaboration
- Local education initiatives
- Long-term relationship development
Because influence is not built through isolated interactions.
It is built through consistency and trust.
Digital Is Changing KOL Influence — But Unevenly
Digital engagement is also reshaping KOL strategy across the region.
For example:
- Singapore and Australia have high adoption of digital scientific engagement
- Thailand and Malaysia are evolving toward hybrid engagement models
- Indonesia and parts of Vietnam still rely heavily on face-to-face interaction
This creates another layer of complexity.
The future of KOL engagement is likely hybrid — but not uniformly so across markets.
What Successful Organisations Do Differently
The organisations that succeed in KOL engagement across Southeast Asia:
- Design KOL strategies market by market
- Combine regional and local KOL approaches
- Invest in long-term relationship building
- Understand institutional and cultural dynamics
- Adapt engagement models to local realities
Most importantly:
They do not assume influence works the same way everywhere.
My Reflection
Across Southeast Asia, KOL engagement is not just about identifying experts.
It is about understanding influence.
And influence in this region is shaped by:
- Science
- Systems
- Relationships
- Culture
- Trust
The organisations that succeed are not those with the largest KOL databases.
They are the ones that understand how influence actually works locally.
Because in this region:
Scientific credibility opens the door.
Local trust drives adoption.
