Use of the Core Content Classification in General Practice (3GCP) for qualitative analysis of context and practice. Ten-year study of undergraduate students’ final works in the Integrated Master's Degree in Medicine at the University of Coimbra.

Background
General Practice/Family Medicine includes approaches to the biological, technological, behavioural, sociological and anthropological domains.

Objectives
To document the domains addressed in the final assignments of the Integrated Master’s Degree in Medicine at the Faculty of Medicine, University of Coimbra, in the area of GP/FM.

Material and methods
Observational study of the titles of final assignments, between 2008 and 2017, granted by the Faculty of Medicine of the University of Coimbra. A domain analysis using as codes the International Classification in Primary Care-2 and the Q-Codes, a context classification in Primary Care, year of elaboration and gender of author was carried out for each title of final assignment. A descriptive and inferential analysis was performed through parametric and nonparametric tests.

Results
169 papers were analysed, 23.1% written by male students, with a positive overall growth dynamics (Δ = +7) between 2008 and 2017. Q-Codes were registered 276 times, while the ICPC-2 codes were used 133 times. Under the Q-Codes, “doctor’s issues” is the most frequently addressed (n = 112; 67.2%), and under the International Classification in Primary Care-2 classifications, the chapter “Psychological” was predominant (n = 35; 21%). Under the Q-Codes, subcategories “primary care setting” (n = 26; 15.6%), “health issue management” (n = 23; 13.8%) and “unable to code, unclear” (22; 13.2%) were dominant. Within the International Classification in Primary Care-2, the subcategories “diabetes noninsulin dependent” (n = 22; 13.2%), “depressive disorder” (8, 4.8%) and “hypertension uncomplicated” (8; 4.8%) were predominantly focused on.

Conclusions
The 3CGP may become a professional tool, allowing for more precise identification of final works, for a better communication method in medical activity and for avoiding the loss of previously developed works
