OUR WELCOME POST: US Deprescribing Research Network

By Cynthia Boyd and Mike Steinman

Though medications offer the capacity to extend lives, relieve symptoms, and reduce the feared consequences of disease, they can also cause bothersome and dangerous side effects, burden older adults and their caregivers, and deplete savings. The use of multiple prescription drugs among U.S. adults age 65 and older has increased from 24% in 2000 to 39% in 2012. This significant growth is attributable to a growing older population, onset of chronic disease, and increasing availability of drugs for treatment and prevention. So, how do we handle the double-edged sword that is medication-treatment? By understanding and identifying the medications that are suitable for each patient, and deprescribing those for which these harms outweigh the benefit.

What is deprescribing? Deprescribing refers to the thoughtful and systematic process of identifying problematic medications and either reducing the dose or stopping the medication in a manner that is safe, effective, and helps people maximize their health and wellness goals.

However, this process is not easy. Little is known about how to best identify which medications are prime for deprescribing, how to safely and effectively stop them, and how to engage older adults, their loved ones, clinicians, and the health system in this process in a seamless and person-centered manner.

The National Institute on Aging recognizes the need for deprescribing medications among older adults and has awarded a five-year, $6.2 million grant to the University of California, San Francisco (UCSF) and Johns Hopkins University to establish the U.S. Deprescribing Research Network (USDeN).

Who we are and what we do – The USDeN is led by Co-Principal Investigators Michael Steinman, MD, at UCSF and the San Francisco VA Medical Center, and Cynthia Boyd, MD, MPH, at Johns Hopkins University School of Medicine. The network is comprised of a community of individuals who share the common goal of developing and disseminating high-quality evidence about deprescribing for older adults, and in doing so, helping improve medication use among older adults and the outcomes that are important to them.

The network’s key activities are designed to provide resources and create a central place for mutual learning, collaboration, building research capacity, and catalyzing work among a large and multidisciplinary group of investigators. Network activities are oriented around 4 cores and a series of working groups:

Investigator Development Core – Organizes activities to provide education and collaboration about deprescribing research, with a special focus on the needs of early-stage investigators.

Pilot and Exploratory Studies Core – Funds and supports pilot and grant planning studies related to deprescribing for older adults.

Stakeholder Engagement Core – Supports engagement of patients, caregivers, clinicians, and health system stakeholders with various activities of the network, so that the resulting research is maximally responsive to their priorities and needs.

Data and Resources Core – Provides information about prior and ongoing research on deprescribing, research resources relevant to deprescribing, and will build capacity for the use of existing electronic health record data for deprescribing research

Working Groups – Supports 4 working groups that will synthesize existing research and develop new tools for deprescribing research, including identifying high-priority targets for deprescribing, optimizing measurement tools and using electronic health data in deprescribing research, and optimizing communication around deprescribing.

We invite you to join our community of innovators by visiting us at https://deprescribingresearch.org, and following us on Twitter @DeprescribeUS. For more information contact admin@deprescribingresearch.org.

Middle-aged men with multimorbidity at greatest risk of death

By Bhautesh Jani and Frances Mair

Our study published in BMC Medicine [1], found that multimorbidity is associated with a higher risk of death from cancer, vascular conditions and all causes of death – even after accounting for lifestyle or demographic factors. The effect of multiple long-term conditions (LTCs) on higher mortality risk was largest among men between 37-49 years.

The study used the UK Biobank cohort (approx. half million adults) and found that the type of LTC, as opposed to the number of LTC, may have an important role to play in understanding the relationship between multimorbidity and death.

This is the first study to examine the relationship of multimorbidity with cancer mortality and we have shown a dose-response relationship between number of LTCs and cancer mortality.

Younger participants, especially men, were observed to have a relatively higher risk of mortality with increasing number of LTCs, and that certain combinations of conditions were associated with a particularly higher risk of death. Going forward, further research is needed to study the impact and management of multimorbidity in middle aged adults, as they may be at higher risk of early death.

The measurement of multimorbidity

By Kathryn Nicholson
Answering an invitation to contribute with an article to a special issue of the journal Health Psychology, we wrote the article entitled “The measurement of multimorbidity” that was recently published [1]. The article was written with the purpose of providing a review of the literature published between 1974 and 2018 that have utilized measures for multimorbidity and to provide guidance on measures to consider when conducting a research study on multimorbidity. The article introduces the reader to the two main groups of measures of multimorbidity that can be distinguished. The first group of measures is constituted by a simple count from various lists of chronic conditions. The second group of measures introduces weighting for included chronic conditions thus creating a “weighted index” of multimorbidity. These two main groups are not mutually exclusive as the list of medical conditions in some weighted indexes can be used as a list of conditions without weighting. This classification does not include measures of multimorbidity which are not based on lists of medical conditions, such as the Cumulative Illness Rating Scale, which includes areas or domains that are grouped under body systems instead of medical conditions. The article shows the variety of existing measurements, highlighting their differences, to provide an overview of the possibilities that are available to a researcher intending to measure multimorbidity. Finally, the article outlines some guidelines for the choice of a measurement of multimorbidity for research studies. We hope that this review of the existing literature will help inform the careful use of these tools by researchers moving forward. In addition to this review, it is advised that readers attempt to keep updated on the ever-increasing multimorbidity literature.

Socio-economic inequalities in life expectancy of older adults with and without multimorbidity

By Madhavi Bajekal, on behalf of the UCL Multimorbidity Project Team
New paper by @ucl_dahr and colleagues [1]: https://doi.org/10.1093/ije/dyz052
Using linked electronic health data for a cohort followed up from 2001 to 2010, we have been able to quantify socio-economic differences in the age of onset of multimorbidity (MM) and, with subsequent mortality, how much of remaining life after age 65 are years lived with and without multiple chronic diseases.
A seminal study by Barnett et al [2] reported a 10y gap in the cross-sectional prevalence of MM at younger ages between the most and least deprived populations in Scotland in 2007.  Our study shows that in England the difference in MM incidence was again about 10y between the most deprived (Q5) and the least deprived (Q1) groups in middle-age (Fig 3), with rates converging at successively older ages.  Health- and life expectancy measures are based on incidence rates (of diseases and of subsequent death); we modelled these to estimate and partition remaining life into years with and without MM.
At age 65, men spend 6.9y without MM and 9.9y with MM; and women, 7.6 y and 11.7y respectively. Overall, men and women spend about 60% of their remaining life in old age with two or more chronic diseases, although this proportion varies by up to 5 percentage points above and below between the two ends of the deprivation spectrum (Tables 2 and 3).
We show that the most deprived groups live, on average, fewer years in total than the least deprived groups, but spend almost the same number of years with MM. In terms of healthcare costs this implies that, although average lifetime resource-spend for both groups might be of a similar magnitude, it is shifted to younger ages for the most deprived groups. The evidence adds weight to the argument calling for a shift to the standard age-cost curve used in the national resource allocation formula to younger ages in deprived areas to reflect greater need earlier in the life course [3].

A multidisciplinary self-management intervention among patients with multimorbidity: Impact of socioeconomic factors

By Martin Fortin
The objective of this study was to analyze the effect of a multidisciplinary self-management intervention among patients with multimorbidity and the impact of socioeconomic factors on the results.
Participants of this study were multimorbid patients from of a pragmatic randomized trial evaluating an intervention that included patients (18 to 75 yrs.) from eight primary care practices in Quebec, Canada. The intervention included self-management support and patient-centered motivational approaches.
Self-management was evaluated using the Health Education Impact Questionnaire (heiQ) which measures eight different domains.
The effect of the intervention on the likelihood of an improvement in self-management was significant in six heiQ domains in the univariate analysis: Health-directed behavior, Emotional well-being, Self-monitoring and insight, Constructive attitudes and approaches, Skill and technique acquisition, and Health services navigation. After controlling for age and gender the results remained essentially the same.
After additional adjustments for family income, education and self-perceived financial status, the likelihood of an improvement was no longer significant in the domains Emotional well-being and Self-monitoring and insight.
It was concluded that the intervention produced significant improvements in multimorbid patients for most domains of self-management but socioeconomic factors had a minor impact on the results.
