What TromboseZorg Dichtbij does

TromboseZorg Dichtbij (TZD) is a Dutch non-profit foundation (stichting) established in 2022 through the merger of the thrombotic services of Result Laboratorium and Canisius Wilhelmina Ziekenhuis (CWZ), headquartered in Druten, Gelderland, Netherlands. The organization provides anticoagulation management services for approximately 18,000 patients on Vitamin K antagonists (acenocoumarol and fenprocoumon), making it one of the larger thrombotic services in the Netherlands. Its core service is INR (International Normalized Ratio) monitoring and dose optimization, delivered through three modalities: standard monitoring via blood collection points operated by partner laboratories (CWZ, Result Laboratorium, Dicoon, Rijnstate); self-management via home POCT devices (CoaguChek XS or Micro INR Meter Link); and Near Patient Testing (NPT) at care institutions.

The underlying technology stack centers on the Tropaz web portal and mobile app — a digital platform that replaced the legacy Portavita system in April 2022 and enables patients to view dose cards, submit INR measurements, communicate with the thrombosis service, and manage appointments. Clinical dosing recommendations are generated through automated processing of structured INR data (Trodis/Tropaz), with mandatory physician review and approval. Operations are ISO 9001:2015 and FNT Veldnorm certified (KIWA Nederland, June 2022) and follow LSKA national care chain standards and LTA guidelines for VKA-DOAC transitions.

TZD generates revenue through three streams reimbursed under Dutch basic health insurance at NZa-set maximum tariffs: standard anticoagulation monitoring (annual billing via CWZ or Result Laboratory); self-management services (quarterly all-inclusive billing including equipment, strips, and supervision); and Near Patient Testing (special NZa rate, with care institutions receiving a portion). Patient acquisition is primarily referral-driven from cardiologists, internists, neurologists, and GPs, supplemented by hospital anticoagulation committee participation and self-enrollment via the website. Since March 2023, TZD has been a member of CAT (Centrum Antistolling Trombosezorg), a national partnership with six other thrombotic services providing shared 24/7 emergency consultation. Geographic expansion is ongoing, with the planned March 2026 transfer of Trombosedienst Gelderse Vallei (Dicoon) patients extending the service area into the Ede region.
