Clinical Trial Summary

The primary objective is to assess the effectiveness of training a clinician to be a 'value champion' within clinical settings to decrease the use of three classes of potentially inappropriate prescription medications (PIMs) among people living with dementia (PLWD). Secondary objectives include determining if the intervention is associated with a reduction in emergency department (ED) visits or hospitalizations due to a fall, and examining five implementation outcomes: appropriateness, feasibility, fidelity, penetration, and equity.

This study is a pragmatic cluster-randomized trial to test the effectiveness of a primary care clinician value champion for de-implementing PIMs among patients 65 years of age and older with a diagnosis of dementia. Medicare Part D pharmacy claims data will be analyzed at the end of the 12-month intervention for the primary outcome, the medication possession rates (MPR) for three groups of potentially inappropriate medications: antipsychotic medications, benzodiazepines, and hypoglycemic medications (sulfonylureas and insulin). In a similar fashion, a hospital admission, or an emergency department visit for a fall will be assessed at the end of the intervention using Medicare claims data. Finally, the five implementation outcomes will be evaluated at the end of the intervention from notes entered by the value champions in project workbooks.

Primary care clinics within each of the two participating ACOs will be randomized to either the intervention or control arms of the study. Prior to random assignment, the investigators will stratify practices based on high versus low historic prescribing rates. A primary care clinician from each clinic selected for the trial in the intervention arm (n=30 across the two ACOs) will be recruited as a clinician value champion for each intervention clinic. The clinician value champion will participate in twice monthly value champion web-based training sessions for six months and then launch a 12-month initiative within the clinician value champions' clinics to reduce PIM prescribing among PLWD. Study outcomes will be assessed 12 months after the clinician value champions launch the initiative.

The hypothesis is that for each medication class, the intervention will produce clinically relevant decreases in mean possession rates of 10% of a standard deviation in patients seen in intervention clinics compared to those who are seen in control group clinics.

Background on Condition, Disease, or Other Primary Study Focus:

For people living with dementia (PLWD) the overuse of Potentially Inappropriate Medications (PIMs), those for which the potential for harm outweighs benefit, remains a persistent problem despite evidence-based guidelines supporting de-adoption. A group of geriatric experts convened by the Choosing Wisely initiative identified three classes of PIMs for PLWD: antipsychotics, benzodiazepines, and hypoglycemics (sulfonylureas and insulin) with adequate glycemic control. In a systematic review the prevalence of PIMs when cognitive impairment was reported ranged from 20.6% to 80.5%. Approximately 14.3% of Medicare Part D enrollees with dementia residing in the general community are prescribed an antipsychotic. The prevalence of potentially inappropriate benzodiazepine prescriptions has been reported to be as high as 20% among elderly persons with dementia living in the community. The proportion of elderly patients with an A1c < 7% who received a prescription for sulfonylurea, insulin or combined insulin and sulfonylurea therapies was 35.2%, 24.2% and 16.3% respectively and was as prevalent in those with dementia as in those without. Park and colleagues compared rates of prescribing low-value medications in the elderly from 2006-2015 in both traditional Medicare and Medicare Advantage. Not only was there no difference in rates between the two groups, there was also no evidence of any decline in rates of prescribing over time, including use of benzodiazepines in PLWD.

Study Rationale:

The rationale for decreasing the use of PIMs is that use in this population of patients results in a greater likelihood of harm than benefit. Documented harms in the medical literature includes falls, worsening cognitive impairment, hospital admission, functional impairment, and death.

Name and Description of the Intervention:

One clinician value champion from each clinic randomized to the intervention arm will complete a value champion training program led by the P.I. and then implement care redesign activities in the clinical practice setting to reduce the use of low value prescribing in older adults with dementia. The 6-month training phase will consist of twice monthly web-based training sessions. A recently completed Robert Wood Johnson Foundation (RWJF)-funded Value Champion Fellowship program resulted in the development of a training curriculum comprised of 10 learning modules for the training phase of the intervention and a project workbook to guide clinician value champions during the 12-month project phase. Following the 6 months of training, clinician value champions will participate in a monthly 1-hour shared learning sessions via video conference to share successes, challenges, and brainstorm solutions for 12 months (months 10-22 of the study). The investigators will invite former value champion fellows and faculty from the RWJF fellowship to participate in these meetings to support this new cohort of value champions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Medication Possession Ratio for any medication in these three classes: antipsychotics, benzodiazepines, or hypoglycemic medication (sulfonylureas or insulin).	The Medication Possession Ratio is calculated from Medicare Part D claims data as quotients with denominator equal to the length of the quarter and the numerators equal to the days supply for prescriptions within the medication class filled during the quarter, plus excess days-supply from the previous period minus excess days-supply remaining at the end.	1 year
Secondary	Number of Emergency Department or Hospitalizations attributed to a fall.	The presence of fall in the 'reason for visit' code on Emergency Department or inpatient visit as indicated by a clinician bill (Medicare art B claims data).	Every 3 months for 18 months
Secondary	Proportion of stakeholders identified by clinician champions as opponents of their improvement project - recoded in Stakeholder log.	This is a measure of Appropriateness. The clinician champions will record stakeholders and whether they are opponents of the improvement project in the Stakeholder Log.	12 months
Secondary	Number of milestones completed by the clinician champions during the "design and implement" phase of their improvement project- recorded in the Value Champions Project Workbook	This is a measure of Feasibility, defined as "…the extent to which a new innovation, can be successfully used or carried out within a given agency or setting." "Design and Implement" milestones are recorded by clinician champions in the Value Champions Project Workbook: Test and Implement section/ milestones.	12 months
Secondary	Total Number of Milestones achieved by each clinician champion during their improvement project. - Recorded in Value Champions Project Workbook.	This is our measure of fidelity, defined as "…the degree to which an intervention was implemented as it was prescribed in the original protocol." Milestone achievement is recorded by clinician champions in the Value Champions Project Workbook. (The workbook is broken into sections by phases of work, and each section has a list of milestones to achieve.)	12 months
Secondary	Total number of stakeholders engaged by each clinician champion within their clinic. - recorded in Stakeholder Log.	This is our measure of penetration, defined as "…the integration of a practice within a service setting and its subsystems."	12 months
Secondary	Number of equity related milestones achieved by each clinician champion during their project. Recorded in the Value Champions Project Workbook.	This is our measure of Equity, defined as "…proactive tailoring of de-implementation strategies to address healthcare inequities and unintended consequences for vulnerable populations." Milestones are recorded by clinician champions in the Value Champions Project Workbook, and several of the milestones throughout the sections are related to equity.	12 months
