Sima Zaheri

Sima_klein.jpgDeputy director

Sima Zaheri has been working at Stichting HIV Monitoring (SHM) since it was set up in 2002 and has been deputy director since June 2017. In the years prior to becoming deputy director, Sima was the manager of SHM’s data and QC unit and part of the management team. Sima studied medical biology at the University of Amsterdam and, since 2002, has focused on setting up and driving the systems for data collection, data processing, quality improvement and quality maintenance. As deputy director, Sima plays an active role in forming SHM’s strategy. On behalf of the director, she is responsible for the day-to-day implementation of this strategy in terms of data & QC, human resource management, finance and control, and organisation and data security, and drives various organization-wide operational management processes. Sima works closely with the HIV-treating physicians, researchers, nurse consultants and others who use SHM’s data in the 26 HIV treatment centres in the Netherlands to ensure that important developments in the HIV and AIDS field are translated into processes, and to monitor the quality and efficiency of these processes on an ongoing basis. Within this context, Sima has managed several innovation and improvement projects.

Ard van Sighem

Senior Researcher

Ard's research involves investigating the course and the changes in the HIV epidemic in the Netherlands from the early 1980s until the present day. To achieve this, Ard uses mathematical modelling as a tool to analyse the relevant data in the ATHENA cohort, the database maintained by Stichting HIV Monitoring, and other national data sources. Ard is investigating how HIV spreads within risk groups, how these risk groups have changed over time, and how interventions would act on the future course of the epidemic.

He is also interested in the more patient-specific side of the HIV epidemic. In particular, Ard is investigating the risk of progression to death in the era of combination treatment in which specific groups of patients can achieve a near normal life expectancy. In addition, he is studying incidence of and risk factors for non-AIDS diseases in the ageing HIV-infected population, in particular their relation with CD4 cell counts and HIV RNA levels.

Lastly, together with the European Centre for Disease Control and Prevention and with colleagues in the United Kingdom and Switzerland, Ard is investigating and improving methods to estimate the size of HIV population in countries within the European Union and the European Economic Area.

Stichting HIV Monitoring

Stichting HIV Monitoring (SHM) makes an essential contribution to healthcare for HIV-positive people in the Netherlands.  Working with all recognised HIV treatment centres in the Netherlands, SHM systematically collects coded medical data from all registered HIV patients. SHM uses these data to produce centre-specific reports that allow HIV treatment centres to optimise their patient care and obtain formal certification. SHM’s data also form the basis for the yearly HIV monitoring report and are used in HIV-related research in the Netherlands and internationally. The outcome of SHM’s research provides tangible input into HIV care and prevention polices in the Netherlands.
