Our Mission

Odense Deprescribing INitiative (ODIN) aims to facilitate more rational use of medication through deprescribing research and implementation activities. ODIN assesses drug use for all patients, in particular older individuals and those with limited life expectancy.

ODIN is a collaboration between research units located in Odense, Denmark: Hospital Pharmacy Funen, Geriatric Department, and Clinical Pharmacology, all at Odense University Hospital, and Clinical Pharmacology, Pharmacy and Environmental Medicine and Research Unit of General Practice, both at the University of Southern Denmark.

Together, ODIN span clinical pharmacy, geriatrics, pharmacology, and internal medicine as well as general practice and sector transitions. The five research units have a long-standing publication record encompassing many different research methodologies ranging from qualitative research over systematic reviews to both observational and clinical research as well as implementation research.

ODIN is part of the task group for ‘Seponeringslisten’, an official list with deprescribing recommendations for selected medications, published yearly by the Danish Health Authority. Further, ODIN is currently co-leading the development of a guideline focused on deprescribing and prevention of polypharmacy in general practice, together with the Danish College of General Practitioners.

On this site, you can read more about the participants in ODIN as well as access ODIN’s current pipeline of activities and previous publications.

Projects

Attitudes towards deprescribing

A portfolio of projects including literature reviews, qualitative studies and quantitative studies to describe patient’s, relatives’ and health care professionals’ barriers regarding deprescribing.

For older individuals reaching the last years of life, continued use of some medications may be of questionable benefit due a limited life expectancy and shifts in goals of care. In such situations, it may therefore be relevant to reduce or discontinue treatment with these medications. Despite this, a number of barriers towards deprescribing have been identified among both patients, relatives, and health care professionals.

In a series of papers, we explore attitudes towards deprescribing from the perspective of both patients, relatives, and health care professionals. We do this to get a better understanding of what may hinder as well as facilitate deprescribing, as this will help us developing interventions, tools, and strategies that may improve the uptake of deprescribing in clinical practice. We explore patient/relative and prescriber perspectives through both systematic reviews, qualitative studies, and surveys.

ODIN-1

A primary care RCT testing a comprehensive deprescribing intervention on quality of life among patients with limited life expectancy.

Numerous deprescribing interventions have been shown to be feasible, safe, and generally effective at reducing medication use. However, the evidence of impact on patient-important outcomes, such as quality of life, is limited.

With ODIN-1, we will test whether a comprehensive and patient-centered deprescribing intervention can improve quality of life as well as other outcomes among older patients with limited life expectancy. The intervention will be focused on aligning medical treatment with patient’s preferences, and it will be carried out in collaboration between patient and general practitioner.

The trial will be initiated during the summer of 2020 and run for one year. The study is funded by the VELUX Foundation.

 

Patient preferences for discussing life expectancy

A portfolio of studies exploring patients’ preferences for discussing life expectancy.

 

A patient’s estimated life expectancy is an essential part of individual care planning in the last part of life. A careful discussion about life expectancy between patients and physicians may assist patients in making informed decisions related to e.g. medication use and deprescribing, screening needs, and personalized care. Several studies have explored patient preferences for discussing life expectancy but the results are conflicting. Further, previous research has primarily focused on the preferences of patients with cancer and to a lesser extent other patient populations where discussions about life expectancy may also be particularly relevant.

In two studies, we explore patient preferences for discussing life expectancy. In the first study, we provide a comprehensive overview of the literature on patient preferences for discussing life expectancy and, in the second study, we examine these preferences in a Danish geriatric outpatient setting.

Characteristics of and use of medication among Danish nursing home residents

A portfolio of register-based studies examining characteristics of and drug use patterns in the Danish nursing home population.

Admission to nursing home generally indicates an altered disease status, a certain level of frailty, and a relatively limited life expectancy, thus representing a time where treatment goals might change from preventive to symptomatic control. To ensure appropriate medication use among nursing home residents, insight into characteristics of and use of medication among nursing home residents is needed.

In a series of studies, we use the nationwide Danish health registries to examine characteristics of and drug use patterns in the Danish nursing home population.

#ICOD2022

We were part of hosting the 1st International Conference on Deprescribing!

The 1st International Conference on Deprescribing (ICOD) was held from September 5-7, 2022 in Kolding, Denmark, and attracted 250 participants from all over the world, including Europe, Asia, Australia and North America. The conference was organized through a partnership with ODIN, the Network of European Researchers in Deprescribing, the University of Southern Denmark and the Danish Society of Clinical Pharmacology.

The conference included keynote lectures, workshops, oral abstract presentations, a poster session, and several social activities. All in all, the conference succeeded in facilitating knowledge exchange and fostering network between new as well as established people in the field of deprescribing. The success of the conference culminated in a special issue of deprescribing in the scientific journal Basic & Clinical Pharmacology & Toxicology.

The 2nd ICOD will be held from September 26-27, 2024 in Nantes, France. You can find more information about the conference here

See you all in Nantes!
