Professor Debi Bhattacharya

I am Professor of Behavioural Medicine at the University of Leicester and a primary care pharmacist. I lead a portfolio of research largely funded by the NIHR plus working with industry and charitable organisations applying behavioural science to medicines optimisation challenges. Two key strands of this work are medication adherence and deprescribing.

Outputs associated with medication adherence projects include:

Medication Adherence Support Decision Aid (MASDA)

Identification of Medication Adherence Barriers Questionnaire (IMAB-Q)

Medication Acceptability Questionnaire (MAQ)


Outputs associated with deprescribing projects include:

Opioid deprescribing toolkit

CompreHensive geriAtRician Led MEdication Review (CHARMER)

I also have a strand of NIHR funded research developing the science of dissemination and implementation; this includes implementing the Opioid Toolkit into the NHS and developing a consolidated framework for dissemination.

I welcome candidates from a variety of disciplinary backgrounds to join my research team. Skill sets that lend themselves particularly well to my programmes of research are a clinical or psychology background. My strands of research all focus on behaviour change; most notably patient behaviour change in the context of medication adherence and practitioner behaviour change in the context of deprescribing.


I have led the design and delivery of a placements programme spanning four years of a pharmacist training programme and clinical masters level module of an MPharm programme. Most recently I established a pharmacist non-medical prescribing programme for which I was course director for six years.

I would be delighted to have the opportunity to comment on topics related to pharmacy and health behaviour change specifically deprescribing and medication adherence.
