Benzodiazepine use risk: Understanding patient specific risk perceptions and medication beliefs.

BACKGROUND

Benzodiazepines are widely prescribed psychotropic medications. These medications have the potential to cause alertness impairing effects and their prolonged use is associated with serious adverse effects. Despite the listed adverse health outcomes and provision of warnings, many benzodiazepine users tend to ignore the safety information and use them inappropriately.

OBJECTIVE

To elicit the risk perceptions of benzodiazepine users and explore the association of risk perceptions with their socio-demographic factors or medication use profiles (e.g. past withdrawal attempt, length of use and future willingness to try behavioural alternatives).

METHODS

Point of purchase surveys were conducted with patients who were supplied benzodiazepines from selected pharmacies across New South Wales (NSW), Australia. Survey items included questions about patient's demographic characteristics, their past attempt for withdrawing benzodiazepines and their future intention to consider alternative behavioural therapies. The validated Beliefs about Medications Questionnaire (BMQ-specific) and a customised scale assessing risk perception were included in the survey. Data obtained from the surveys were entered into the IBM SPSS package (Version 22.0) and subjected to descriptive, correlational and regression analyses.

RESULTS

Seventy-five patients (67% female, a mean age of 54.3) obtaining benzodiazepines from 12 pharmacies were recruited for the survey. Participant's beliefs regarding potential side effects of benzodiazepines and their level of education were significantly associated with their risk perception scores. While the overall risk perception scores did not influence patient's previous attempts to withdraw benzodiazepines, the risk perception score about immediate effects of benzodiazepines (within 3-4 h of consumption) was a predictor of preference for behavioural therapies. Eighty-three percent (n = 62) of the participants believed that pharmacists can play a key role in improving risk perceptions of consumers around benzodiazepine use.

CONCLUSIONS

Individual patient characteristics and their beliefs about medications significantly influence their perception of risk about benzodiazepine use. The findings of this study suggest that pharmacist support can be utilized in effective risk communication, promoting the safe use of benzodiazepines and in facilitating the uptake of relevant behavioural interventions as alternatives to benzodiazepines.
