Abstract
Background: Information on the extent of high-risk prescribing for nonsteroidal anti-infammatory drugs (NSAIDs) across developing countries is scarce. Objectives This study examines the prescribing pattern for NSAIDs in primary care, assesses the extent of high-risk NSAIDs prescribing and identifes associated factors. Setting 129 public and 416 private primary care clinics in Malaysia. Methods Data were derived from the National Medical Care Survey 2014, a cross-sectional survey on primary care morbidity patterns and clinical activities in Malaysia. Types of NSAIDs, indications for NSAIDs use and propor tion of high-risk NSAIDs prescribing were assessed. Factors associated with high-risk NSAIDs prescribing were identifed with a multivariable logistic regression. Weighted results, adjusted for sampling design and non-response were presented.
Main outcome measures: Prescribing pattern of NSAIDs, proportion of high-risk NSAIDs prescribing and its associated factors. Results Among the 55,489 patients who received NSAIDs, diclofenac was the most frequently prescribed NSAID (40.5%, 95% CI 40.1–40.9%), followed by mefenamic acid (29.2%, 95% CI 28.8–29.6%). The commonest indications for NSAIDs use were musculoskeletal condition and respiratory tract infection, both at 17.8% (95% CI 17.4–18.1%). A total of 22.9% (95% CI 22.6–23.3%) patients received high-risk NSAID prescriptions. Of these, 47.8% (95% CI 46.9–48.7%) did not receive adequate gastroprotection despite being at risk, 24.8% (95% CI 24.0–25.5%) were prescribed NSAIDs despite having cardiovascular comorbidities and 22.4% (95% CI 21.7–23.2%) were prescribed high-dose NSAIDs. The odds of receiving high-risk NSAID prescriptions increased with the number of drugs prescribed (OR 1.23, 95% CI 1.06–1.43) and the number of diagnoses in one visit (OR 2.21,95% CI 1.71–2.86). The odds of being prescribed high-risk NSAID prescriptions were lower in patients with secondary (OR 0.52, 95% CI 0.35–0.77) and tertiary education (OR 0.39, 95% CI 0.22–0.68) compared to patients without formal education. Patients’ citizenship, indication for NSAID prescriptions and whether a medical certifcate was issued were also signifcantly associated with the likelihood of receiving high-risk NSAID prescriptions.
Conclusions: A quarter of NSAIDs prescribed in Malaysian primary care setting is categorised as high-risk prescribing. Targeted strategies are necessary to improve patient safety.
