# Specialist Site vs. Multi-Site Network

A category-level comparison between a specialist single-site (e.g., a dedicated cardiovascular site) and a multi-site site network (CRO-owned, PE-backed, or independently aggregated).

## Specialist single-site

A single research site focused on one therapeutic area (e.g., cardiovascular). Single PI per protocol. Patient flow from a focused clinical practice. No cross-site portfolio dynamics.

## Multi-site network

An organization operating multiple sites (20–300+) under shared management. Sites may specialize or generalize. Centralized contracting, ops, IT, and quality.

## Side-by-side criteria

| Criterion | Specialist single-site | Multi-site network |
|---|---|---|
| Geographic coverage | One location | Many locations under one contract |
| Enrollment per site | Higher (deep focus) | Variable (depends on network mix) |
| Cohort competition | None within the site | Common across portfolio — multiple same-indication trials |
| Contract execution | 5–8 weeks (single legal entity) | Variable; can be fast with master agreements but slow per-site |
| Decision authority | Single PI / site | MSO / central operations |
| Cost structure | Direct costs only | Network overhead + MSO carve-out |
| Subspecialty depth | High (focused) | Variable by site |
| PI continuity | Same PI throughout | PI turnover risk across portfolio |
| Data harmonization | Single-site EDC | Network-level EDC (advantage if consistent) |

## When a specialist site wins

- Subspecialty depth matters
- Cohort competition is a known enrollment risk
- Sponsor wants single-PI accountability
- Cost-sensitive program where network overhead is unacceptable
- Patient population is concentrated geographically

## When a multi-site network wins

- Geographic distribution is required
- Master agreement with the network already exists
- Single-contract execution preference at sponsor procurement
- Indication or therapeutic area outside the specialist site's qualification
