Abstract BackgroundThere have been recent concerns about the potential for the use, misuse and abuse of prescription drugs including gabapentin, pregabalin and oxycodone. Over recent years, an increase in deaths associated with these drugs in England has been observed. Aims & ObjectivesThis study sought to characterise general practice prescribing trends for gabapentin, pregabalin and oxycodone – termed dependence forming medicines (DFM) – in England and identify potential demographic characteristics associated with variation if found. MethodsPrescription data from five consecutive financial years (2013/14-2017/18) from general practices in England were aggregated and linked to practice demographics and other information. Longitudinal trends of prescribing, and variation in prescribing trends at practice and clinical commissioning group (CCG) level were analysed.
Results
Annual prescriptions of gabapentin, pregabalin and oxycodone increased each year over the period. Higher prescribing rates per head were associated with greater GP practice deprivation quintile, where the most deprived quintile of GP practices prescribed 313% (p<0.001) and 238% (p<0.001) greater volumes of gabapentin and pregabalin per person than practices in the least deprived quintile. The highest prescribing CCGs were predominantly in northern and eastern regions of England.
Conclusions
Substantial increases in gabapentin, pregabalin and oxycodone prescriptions are concerning and may be associated with avoidable iatrogenic harm from drug-related morbidity and mortality. More research is needed to understand the reasons for the large variation in prescribing between practices, and to develop interventions to reduce unwarranted variation and thereby improve the appropriateness of DFM prescribing.
