Integrating partner notification and contact tracing services across Europe: findings from the Integrate project.

BACKGROUND: Partner notification/contact tracing (PN/CT) is a process whereby people diagnosed with an infectious disease notify their sexual and needle-sharing partners/close contacts and invite them for testing and treatment due to exposure to the disease. PN is a necessary testing and prevention tool supported by the European Centre for Disease Prevention and Control (ECDC) and World Health Organization (WHO). Traditionally, PN efforts have been siloed within disease areas, with separate pathways and systems responsible for specific diseases. The INTEGRATE project sought to improve PN/CT outcomes by sharing knowledge across diseases and countries. METHODS: INTEGRATE used two mapping exercises to assess the PN landscape in Europe and identify areas for integration and cross-learnings for Sexually Transmitted Infections (STIs) and Tuberculosis. Mapping exercises were surveys to 29 consortium partners and in-depth qualitative interviews at four selected pilot sites: Ireland, Greece, Romania and Italy. RESULTS: Areas for the improvement of PN/CT emerged: lack of resources and insufficient staff training, different modes of disease transmission, country-specific laws and regulations, the advent of General Data Protection Regulation (GDPR), differences in healthcare system pathways, historical concerns, and cultural differences. Activities highlighted key areas PN/CT outcomes could be improved, including PN/CT specific trainings for staff, improving knowledge on laws, regulations, guidelines and pathways and creating a country/region specific Standard Operating Procedures (SOPs) for PN/CT, incorporating information on all four disease areas. Findings were analyzed and three key areas were identified and implemented for knowledge transfer namely the creation of an online repository of European country guidelines, the transfer of SOPs and PN training in pilot sites. CONCLUSION: A major finding of the project was challenges associated with incorporating Tuberculosis (TB) contact tracing alongside other infectious diseases. Professionals in the field, emphasized that integrating TB contact tracing with the other disease areas would be challenging and arguably unjustified, due to the different ways of transmission of TB and because well-established historical pathways for TB in public health systems already exist. However, the success of TB services presents an ideal model to draw from when strengthening PN systems for other infectious diseases.

Genetic basis of aminoglycoside resistance following changes in aminoglycoside prescription patterns.

Aminoglycosides (AG) offer an important therapeutic option for the treatment of infections caused by multiresistant Enterobacteriaceae. We observed a change in AG usage patterns in our institution between 1997 and 2006, namely a reduction in use of all AG except amikacin. We studied the changes in AG susceptibility rates in these time periods and correlated with prevalence of different molecular resistance mechanisms. Enterobacteriaceae isolated from blood cultures from 1997 and 2006 were studied. Susceptibilities to AG were determined with the disk diffusion method. PCR was used to detect genes encoding AG-modifying enzymes and methylases. Gentamicin resistance rates dropped from 14·5 to 8·8%, whereas resistance rates to other AG remained unchanged. The AAC(6')-I+AAC(3)-I combination was more common in 1997, whereas AAC(6')-I was the most common mechanism in 2006. Reduction in gentamicin use may preserve the usefulness of this agent against severe infections by multiresistant bacteria such as carbapenemase-producing Enterobacteriaceae.
