Hadoks

Hadoks short for Haaglandse dokters, is an organization established by and for general practitioners in the Haaglanden region. Their mission is to elevate the quality of care services provided by general practices spread across The Hague, Wassenaar, Rijswijk and Leidschendam-Voorburg. Care services include two departments:

  1. Primary Emergency Care: providing urgent care services for approximately 600 GPs in the region, covering out-of-hours care, and

  2. Quality Support: Assisting around 150 practices with the implementation of structured care programmes, including Diabetes Type 2, cardiovascular diseases and risk management, COPD, and asthma, and care for vulnerable older adults.

Hadoks systematically records data on care delivered during evening, night, weekend, and holiday shifts, known in Dutch as Avond-Nacht-Weekend-zorg (ANW-zorg). This includes both planned and unplanned, as well as routine and acute care, provided across three emergency GP centers: HMC Westeinde, HMC Antoniushove, and Haga Hospital.

It is important to note that Hadoks maintains a rigorous policy regarding the use of its data for research. The application process is thorough and time-consuming, and approval is not guaranteed.
