[Factors associated with low adherence to medication in older adults].

Tavares NU, Bertoldi AD, Thumé E, Facchini LA, França GV, Mengue SS - Rev Saude Publica (2013)

Bottom Line: To assess factors associated with low adherence to pharmacotherapy in older adults.The factors significantly associated to low adherence to treatment were: age (65 to 74 years old), not having health insurance, having to purchase (totally or partially) their own medicines, having three or more morbidities, having functional disabilities and using three or more medicines.The increased use of medicines by older adults, because of the high prevalence of non-communicable diseases in this group, and the access to the treatment need to be considered by health care professionals regarding fostering adherence to treatment, which increases therapeutic solutions and quality of life among older people.

ABSTRACT

Objective: To assess factors associated with low adherence to pharmacotherapy in older adults.

Methods: Cross-sectional population-based study, with a representative sample of 1,593 individuals aged 60 or older, living in the urban area of Bagé, RS, Southern Brazil, in 2008. A multiple stage sampling model was used. The data were collected through individual household interviews. The analyses of the association between low adherence regarding pharmacotherapy, measured using the Brief Medication Questionnaire (BMQ), and demographic, socioeconomic, behavioral, health, assistance and prescription factors were carried out applying Poisson regression model to assess crude and adjusted prevalence ratios, their respective 95% confidence intervals and p-value (Wald test).

Results: Around 78.0% of individuals reported have taken at least one medication in the seven days prior to the interview. Of these, approximately one third (28.7%) were considered to have low adherence to the treatment. The factors significantly associated to low adherence to treatment were: age (65 to 74 years old), not having health insurance, having to purchase (totally or partially) their own medicines, having three or more morbidities, having functional disabilities and using three or more medicines.

Conclusions: The increased use of medicines by older adults, because of the high prevalence of non-communicable diseases in this group, and the access to the treatment need to be considered by health care professionals regarding fostering adherence to treatment, which increases therapeutic solutions and quality of life among older people.

Mentions: A Poisson regression model was used to estimate adjusted and unadjusted prevalenceratios and 95% confidence intervals (95%CI), considering the sample design effectusing the Stata svy command. Confounding factors were controlled for in themultivariate analysis using a hierarchized analysis model (Figure). Variables with p < 0.20 were included in themultiple model and a 5% level of significance was adopted for variables to remain inthe model, using backward elimination of the variables. The statistical significanceof the prevalence ratios obtained in the Poisson regression models were evaluatedusing the Wald test.
