Abstract

Objective: The objective of this study is to assess if the deprescription of medications that are considered low intrinsic value medications such as the chondroprotectors or SYSADOA entails a symptomatic worsening of the arthrosis and consequently an increase of the consumption of analgesics.

Material and Methods: Following the usual clinical practise, the SYSADOA treatment was withdrawn to the patients from a Primary Health Care Centre (assigned population: 34,382 inhabitants, 17% up to 65 years old) according to the published scientific proof and the recommendation of the health administration consisting of reducing the treatments with low intrinsic value medications. Differences in consumption of analgesics and AINEs between a previous period before the withdrawn and the same period post-withdrawn were studied through an observational post-intervention study.

Results: 354 patients were analysed (68,4% women, average age 66,2 years). There were not found significant differences from a statistical point of view in the total consumption of analgesia in the 6 months period post-withdrawn (average of 3,97 packagings) compared to the previous period of 6 months (average of 4,04 packagings). When stratifying by ATC code, age and gender, there were only found differences in the consumption of other analgesics and antipyretics taking into account the sex.

Conclusion: It is concluded that considering together with the patient the deprescription of SYSADOA according to doctor’s criteria is safe and does not involve an increase of analgesics consumption (other analgesics, antipyretics, AINEs, major and minor opiods) suggesting that it does not suppose a worsening of the arthrosis disease. Besides, the deprescription of SYSADOA may contribute to reduce polymedication without disrupting the clinical situation and avoid possible risks of adverse effects or potential interactions.
