Quality improvement project - Reducing the inadvertent prescribing of unopposed estrogen in primary care Dr Liz Horrocks Banstead PCN.

Objective: The aim of the project was to reduce the risk of patients using the estrogen only part of their hormone replacement therapy (HRT) inadvertently in Banstead PCN. Although understanding about the risk of unopposed estrogen is well understood by prescribers, there are numerous flash points where this exposure can occur which was highlighted by several cases encountered during a study period of 3 months.

Study design: Cases encountered revealed numerous reasons for this exposure which were split into three areas: Prescribing factors, dispensing checks and patient understanding.

Main outcome measures: Quality improvement suggestions were tailored to the factors involved. IT system changes to EMIS, our main computer software provider, were proposed to enable safer prescribing. Following discussion with key stakeholders, increased education for pharmacists was proposed alongside an alert sticker system at the dispensing end point. Patient understanding and education for all parties was delivered through various routes.

Results: The IT system alterations required are complex and still awaited. Funding was obtained and stickers distributed. The results from a re-audit from this intervention are awaited. Interim education measures at an individual level were meantime explored and the impact of them assessed. Patient education and the role of social media were explored. I produced a short video which was circulated to doctors with the plan to distribute via other clinician social media accounts.

Conclusions: A key discovery through this study is that many of the flash points identified can be difficult to detect and many are not measurable. The increasing number of HRT prescriptions, time pressures in primary care and the known risk from using unopposed estrogen of endometrial cancer means these changes are of potential great value.
