The Maresme Study Group on Community-Acquired Pneumonia and COPD (GEMPAC, from its Catalan name Grup d'Estudi al Maresme de la Pneumònia Adquirida a la Comunitat i la MPOC) is a consolidated group recognised by the Agency for University Grants of the Generalitat of Catalunya (AGAUR). This group is physically located at the Maresme Health Consortium, which covers primary health care in the Maresme region and is centred in the Mataró Hospital and has a collaborative agreeement with the IGTP for research activities. The group has been led by Dr Jordi Almirall for more than 25 years and carries out epidemiological studies for lower tract respiratory infections; these studies are coordinated by the Mataró Hospital. Its researchers have made important contributions in the areas of incidence, microbiology, prognostic risk factors, costing, diagnostic errors and the value of inflammatory markers for the prediction of pneumonia and aetiological orientation.

The group has been awarded eight FIS grants in which different specialists have participated as principal investigators including family doctors, hospital specialists and house doctors, both from Mataró and other hospitals; nursing staff have also taken part. Since 2006 the group is a part of the CIBERES network, within the Group 14 led by Dr Antoni Torres from the Clinic Hospital Barcelona and Barcelona University for research into aetiology, prognostic risk factors associated with community acquired lower tract respiratory infections (LRTI).

GEMPAC researchers have also participated in as partners in European projects such as GRACE (Genomics to combat Resistance against Antibiotics in Community acquired LRTI in Europe) of the Sixth framework programme priority. Since 2012, they have participated in the European Network COMBACTE CLIN-Net and LAB net (Innovative Initiatives in Medicine) to carry out clinical trials with new antibiotics with the coordinators Dr H. Goossens (Antwerp) and Dr Harbarth (Geneva). The team is also currently part of the PREPARE project (Work Packages 3 and 5).

The group has eight contracts with pharmaceutical companies to carry out clinical trials. It has generated seven doctoral theses in recent years with another three currently in progress and has 40 international publications and 30 more in Spanish journals with a total impact factor of 204.

Keywords: Community health, pneumonia, aspiration pneumonia, COPD.

    Graduated in Medicine and Surgery from Universitat Autònoma de Barcelona in 2000, Ramon Boixeda specialised in Internal Medicine at the Mataró Hospital in 2006, where he is head of the Internal Medicine Department since 2019.

    Boixeda obtained his PhD in respiratory infections from Universitat Autònoma de Barcelona, with more than 25 publications in pneumonia and COPD. He is a member of the COPD Group of Sociedad Española de Medicina Interna (SEMI), collaborating in all research projects focused on the comorbidity of COPD patients, with multiple publications, communications and presentations at national conferences. He is also coordinator of the GEMPAC research group (Grup d'Estudi del Maresme de la Pneumònia Acquirida en la Comunitat), accredited by ACUR, with multiple population-based FIS projects focused on pneumonia, COPD and asthma.

    Boixeda is also a clinical associate professor at the University of Barcelona, ​​an accredited tutor for Internal Medicine residents and secretary of the Board of the Maresme Branch of the Academy of Medical Sciences of Catalonia and the Balearic Islands.
