Perceived medication use challenges and coping strategies among medical outpatients in Nigeria

Abstract

Background: The use of medicines is an action that involves a change in behaviour and it is a complex construct involving reciprocal interactions between social, environmental and cognitive factors. This is particularly true when a patient uses medicines for asymptomatic chronic conditions, requiring life-long use.

Objective: To identify patient-perceived medication use challenges, determine the coping strategies used and investigate the relationship between patient-perceived challenges and self-initiation of coping strategies.

Setting: A premier 900-bed tertiary/teaching hospital located in Ibadan, Nigeria.

Method: Ten pharmacists conducted cross-sectional medication use interviews for a random sample of 324 medical outpatients in 4 weeks (25th October-19th November 2006).

Main outcome measure: Patient-perceived challenges with prescribed medications, self-initiated coping strategies used and relationship between patient-perceived challenges and self-initiation of coping strategies

Results: Eighty-one percent (324) of the random sample of 400 patients consented and completed the interview. Of these, 50.3 % were males while 49.7 % were females with mean age (SD) of 51.5 (17.6) and 52.1 (17.4) years respectively. The most frequent diagnoses were hypertension (53 %) and type-2 diabetes + hypertension (14.5 %). Two hundred and twenty-four patients reported one or more perceived challenges. Of these, 43.8 % were 65 years or older and about half reported at least 3 challenges. The majority (95.6 %) of patients who reported perceived challenges initiated one or more coping strategies without the knowledge of their physicians or pharmacists. Of 100 patients who did not report any perceived challenge, 43 % admitted initiating strategies to maintain perceived "cure" of their medical conditions. Self-initiation and use of coping strategies was far more likely among patients who reported perceived challenges (OR: 28.4, 95 % CI 26.1-30.5). The number of coping strategies reported appeared strongly related to the number of perceived challenges (r = 0.91, p < 0.001).

Conclusion: Perceived challenges associated with the use of prescribed medications and self-initiation of coping strategies appeared considerable among medical outpatients at a major teaching hospital in Nigeria. The risk of unauthorised initiation and use of varieties of coping strategies without the knowledge of clinicians was very high among patients who reported at least one perceived challenge.
