摘要
Background: Drug consumption in the general population is concentrated in the elderly. The aim of this study was to assess the pharmacological profile of elderly people 75 years of age and older, to assess the relationship with the cognitive function and the variables associated with drug consumption.
Methods: This is an epidemiological, cross-sectional, door-to-door study among the non-institutionalised population in a rural area. Participants were inhabitants aged 75 and older from the Angles Primary Healthcare Area (Girona). Drug prescriptions were recorded from participants' medicine chest. Cognitive function was assessed using the Mini-Mental State Examination.
Results: A total of 875 individuals took part (82%). Participants with mild and moderate cognitive impairment consumed an average of 4.6 (SD = 2.9) and 5.2 (SD = 3.2) drugs, participants without cognitive impairment consumed an average of 4 (SD = 2.7) drugs (P < 0.005). In the bivariate analysis, taking into account the degree of cognitive impairment, there was a change in drugs acting on the digestive tract and metabolism (P = 0.003) and nervous system (P = 0.001). Multivariate analysis identified four variables associated with the central nervous system drugs: age, sex, comorbidity and suspicion of depression (P < 0.05).
Conclusions: Participants with severe cognitive impairment had a higher frequency of antipsychotic and antidepressant drug consumption. However, the multivariate analysis shows that advanced age, female sex and suspicion of depression are variables associated with a higher central nervous system drug consumption.
