Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Why this research is important? It is estimated that over one third of all older adults are prescribed medication which are known to have "anticholinergic" side effects. These anticholinergic side effects can include an increased risk of falls, delirium, and memory problems. People who have a high number of anticholinergic medications have an increased risk of these side effects. This can be measured as their anticholinergic burden (ACB). Several tools have been developed to assess the ACB score, by checking a person's medication list, with the aim of reducing these medications where possible (deprescribing).

The study aim The project team worked with a company to design an online tool which can calculate the total ACB score for patients using their electronic medication list. It can also list the individual anticholinergic medications contributing to that score. Patients with high ACB score will be highlighted to healthcare staff including pharmacists, nurses, and doctors. In this project, we plan to understand how this tool can be used by clinicians in older persons wards to reduce the number of anticholinergic medications prescribed where appropriate.

Our approach Working with doctors and pharmacists in one large hospital, we agreed how the tool should be used. First, pharmacists with check weekly using the digital tool how many patients have high ACB scores. Then they would highlight in patients' medical notes the list of medications with high anticholinergic effects using a sticker note. The doctor looking after the patient then sees the note which would prompt him/her to either stop the drug, reduce the dose or switch to a safer drug.

We will test this intervention among 50 patients admitted to older people wards. We will collect information before and after receiving the intervention including number and type of medications prescribed, quality of life, and cognition. We will also talk to staff and patients to understand their views about the intervention, any challenges, and how to improve the process.

Involving patients and public Two patient and public contributors have been actively involved in developing this research proposal. They represent an older person with comorbidity and polypharmacy and a carer, and both have lived experience of managing polypharmacy following hospital admission. They will continue to provide input on study procedures and materials and contribute to plans for sharing the findings.

Sharing the study findings We will share the findings with public, health professionals, researchers and policymakers through plain English summaries, social media, policy briefing documents, scientific papers, conferences and other meetings.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients aged 65 years or more admitted to one of the five Medicine for Older People wards, who have ACB score of 3 or more

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
