[Electronic medical records: Evolution of physician-patient relationship in the Primary Care clinic]. / Historia clínica electrónica: evolución de la relación médico-paciente en la consulta de Atención Primaria.

INTRODUCTION: The introduction of electronic medical records and computer media in clinics, has influenced the physician-patient relationship. These modifications have many advantages, but there is concern that the computer has become too important, going from a working tool to the centre of our attention during the clinical interview, decreasing doctor interaction with the patient. The objective of the study was to estimate the percentage of time that family physicians spend on computer media compared to interpersonal communication with the patient, and whether this time is modified depending on different variables such as, doctor's age or reason for the consultation. MATERIAL AND METHODS: An observational and descriptive study was conducted for 10 weeks, with 2 healthcare centres involved. The researchers attended all doctor- patient interviews, recording the patient time in and out of the consultation. Each time the doctor fixed his gaze on computer media the time was clocked. RESULTS: A total of 436 consultations were collected. The doctors looked at the computer support a median 38.33% of the total duration of an interview. Doctors of 45 years and older spent more time fixing their eyes on computer media (P<.05). CONCLUSIONS: Family physicians used almost 40% of the consultation time looking at computer media, and depends on age of physician, number of queries, and number of medical appointments.

¿Estaría indicada la heparina para prevenir trombosis venosa profunda en pacientes inmovilizados por lesiones menores en miembros inferiores? / Should patients with inmovilization of the lower limb be treated with low molecular weight heparin for preventing deep vein thrombosis?

La profilaxis con heparina de bajo peso molecular (HBPM) es eficaz para reducir el riesgo de trombosis venosa profunda (TVP) en pacientes es cayolados por traumatismo menor en miembros inferiores. Para prevenir una TVP es necesario tratar a 23 pacientes (de 13 a 84 para un intervalo de confianza del 95 per cent) durante aproximadamente 20 días (AU)
