简要总结
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.
详细描述
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.

结局指标
主要结局
Medication Possession Ratio (MPR) for Any Antipsychotics Medication
时间窗: 21 months
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.
Medication Possession Ratio (MPR) for Any Benzodiazepine Medication
时间窗: 21 months
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.
Medication Possession Ratio (MPR) for Insulin Medication
时间窗: 21 months
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.
Medication Possession Ratio (MPR) for Any Sulfonylureas Medications
时间窗: 21 months
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.
