Potentially inappropriate prescribing includes the use of medications that may no longer be necessary or that may increase the risk of harm. Inappropriate prescribing can increase the overall symptom burden, and negatively affect health-related quality of life and function. The inappropriate prescription of certain drug categories such as sedative/hypnotics, antipsychotics, and strong anticholinergic agents poses particular risks for older adults, and may be more common among those with Alzheimer's disease and Alzheimer's disease- related dementias (AD/ADRD) due to a higher prevalence of multimorbidity and more frequent prescription of five or more medications. The D-PRESCRIBE-AD (Developing a PRogram to Educate and Sensitize Caregivers to Reduce the Inappropriate Prescription Burden in Elderly with Alzheimer's Disease) study will test a health plan-based intervention using the NIH Collaboratory's Distributed Research Network, which employs the Food and Drug Administration (FDA) Sentinel System infrastructure. The overarching goal of this randomized controlled trial is to assess the effect of a patient/caregiver- centered, multifaceted educational intervention on potentially inappropriate prescribing in patients with AD/ADRD. The research hypothesis is that education on inappropriate prescribing among patients/caregivers and their providers can reduce medication-related morbidity in patients with AD/ADRD and improve medication safety for this vulnerable population. The study population will include community-dwelling patients with AD/ADRD, identified based on diagnoses codes of AD/ADRD or use of a medication for Alzheimer's Disease, who have evidence of potentially inappropriate prescribing the three drug classes above. The trial will evaluate the effect of mailed educational interventions, including the effect of a second reminder mailing, designed to spur patient/caregiver-provider communication about medication safety (versus usual care) on the proportion of patients with inappropriate prescribing, the primary outcome of this study. The trial will be conducted in two large, national health plans.

Absence of Inappropriate Medication Prescription Dispensing
The primary outcome will be defined as absence of any dispensing of the targeted inappropriate prescription class from day 91 to day 270 during the 9 months following receipt of intervention. These 9 months are split into a 3-month black-out period followed by a six-month observation period, or days 91-270.
Time frame: 9 months
Dose Change
Dose change (defined as \> 50% reduction in dose of the selected inappropriate medication), assessed at the participant level using health claims data (outpatient dispensing) during days 91-270.
Time frame: 9 months
Polypharmacy
Proportion of patients with polypharmacy (defined as \>5 active prescriptions for different agents) during days 91-270.
Time frame: 9 months
Rates of Health Care and Emergency Care Utilization
Rates of: emergency room visits; rates of hospitalizations; rates of non-acute institutional stays (e.g., skilled nursing facilities); and overall health care utilization (number of outpatient visits, days hospitalized, emergency department visits, and non-acute institutional days) during days 91-270.
Time frame: 9 months
Mortality
In-hospital all-cause mortality during days 91-270.
Time frame: 9 months
Switching within Classes
Switching of agents within the following targeted drug classes: sedative/ hypnotics, antipsychotics, highly anticholinergic agents.
Time frame: 9 months
