Rural disparities in emergency department utilization for migraine care.

OBJECTIVE: To evaluate differences in emergency department (ED) utilization and quality of care for migraine in patients with rural and nonrural residences. BACKGROUND: Migraine is a significant problem in the United States with direct health-care utilization cost amounting to US $4.2 billion annually. A considerable portion of this cost is attributed to more than 4 million annual ED visits for migraine and headache. Previous research has documented health disparities among rural populations in other disease states, which can be influenced by factors such as socioeconomic status and health-care access. Given these associations, it was hypothesized that patients with rural residence in a national sample would have increased ED utilization for migraine compared to patients with nonrural residence. METHODS: This was a cross-sectional epidemiologic study to evaluate rural disparities in ED utilization and quality of care for migraine in the United States in 2019. ED encounter data were collected from the Healthcare Cost and Utilization Project (HCUP) Nationwide Emergency Department Sample (NEDS) and Kentucky State Emergency Department Database (KY-SEDD). The primary outcome was crude and age-adjusted rates of ED encounters for migraine per 10,000 population. ED encounters were included if they had a primary International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis code of G43.xx. ED encounters lacking sufficient data to classify into a geographic group were excluded. Secondary outcomes examined differences in quality of care, including mean ED charges and the proportion of encounters with medication administration, imaging, and nerve block service codes between groups. RESULTS: One hundred eighty-three thousand two hundred eleven national ED discharges were classified as rural patient encounters and 627,176 were classified as nonrural. The rural group had significantly higher crude and age-adjusted rates of ED utilization for migraine (crude: rural 39.8, 95% confidence interval [CI] 36.9-42.7; nonrural 22.2, 95% CI 21-23.5 and age-adjusted: rural 41.8, 95% CI 38.8-44.8; nonrural 23.4, 95% CI 22.1-24.7). Opioid utilization was higher in rural encounters (rural n = 26,764, 14.6%; nonrural n = 50,367, 8%; p < 0.001). A Kentucky sub-analysis found 5210 ED discharges were classified as Appalachian and 12,551 as non-Appalachian. The Appalachian group had significantly higher ED utilization rates for migraine compared to the non-Appalachian and national rural groups (crude: Appalachian 44.9, 95% CI 43.7-46.2; age-adjusted: Appalachian 47.4, 95% CI 46.1-48.8). The Kentucky Appalachian group also demonstrated significantly higher opioid analgesia use compared to the national rural group (Appalachian n = 1031, 19.8%; p < 0.001). CONCLUSION: This study suggests rural populations, particularly in Appalachia, may experience significantly higher ED utilization for migraine compared to nonrural patients. Moreover, rural populations were more likely to receive suboptimal migraine management with opioid analgesia. Multimodal health-care interventions should be developed to improve access to outpatient migraine care and further investigate potential risk factors in the rural population. With high ED utilization, the Appalachian population may benefit most from such an intervention.

Acceptability of patient-centered, multi-disciplinary medication therapy management recommendations: results from the INCREASE randomized study.

BACKGROUND: Polypharmacy and inappropriate medications may be a modifiable risk factor for Alzheimer's Disease and Related Dementias (ADRD). Medication therapy management (MTM) interventions may mitigate medication-induced cognitive dysfunction and delay onset of symptomatic impairment. The objective of the current study is to describe an MTM protocol for a patient-centered team intervention (pharmacist and non-pharmacist clinician) in a randomized controlled trial (RCT) directed at delaying the symptomatic onset of ADRD. METHODS: Community dwelling adults 65 + years, non-demented, using ≥ 1 potentially inappropriate medications (PIM) were enrolled in an RCT to evaluate the effect of an MTM intervention on improving medication appropriateness and cognition (NCT02849639). The MTM intervention involved a three-step process: (1) pharmacist identified potential medication-related problems (MRPs) and made initial recommendations for prescribed and over-the-counter medications, vitamins, and supplements; (2) study team reviewed all initial recommendations together with the participants, allowing for revisions prior to the finalized recommendations; (3) participant responses to final recommendations were recorded. Here, we describe initial recommendations, changes during team engagement, and participant responses to final recommendations. RESULTS: Among the 90 participants, a mean 6.7 ± 3.6 MRPs per participant were reported. Of the 259 initial MTM recommendations made for the treatment group participants (N = 46), 40% percent underwent revisions in the second step. Participants reported willingness to adopt 46% of final recommendations and expressed need for additional primary care input in response to 38% of final recommendations. Willingness to adopt final recommendations was highest when therapeutic switches were offered and/or with anticholinergic medications. CONCLUSION: The evaluation of modifications to MTM recommendations demonstrated that pharmacists' initial MTM recommendations often changed following the participation in the multidisciplinary decision-making process that incorporated patient preferences. The team was encouraged to see a correlation between engaging patients and a positive overall response towards participant acceptance of final MTM recommendations.

Patients' attitudes toward deprescribing and their experiences communicating with clinicians and pharmacists.

Purpose: Developing effective deprescribing interventions relies on understanding attitudes, beliefs, and communication challenges of those involved in the deprescribing decision-making process, including the patient, the primary care clinician, and the pharmacist. The objective of this study was to assess patients' beliefs and attitudes and identify facilitators of and barriers to deprescribing. Methods: As part of a larger study, we recruited patients ⩾18 years of age taking ⩾3 chronic medications. Participants were recruited from retail pharmacies associated with the University of Kentucky HealthCare system. They completed an electronic survey that included demographic information, questions about communication with their primary care clinician and pharmacists, and the revised Patients' Attitudes Toward Deprescribing (rPATD) questionnaire. Results: Our analyses included 103 participants (n = 65 identified as female and n = 74 as White/Caucasian) with a mean age of 50.4 years [standard deviation (SD) = 15.5]. Participants reported taking an average of 8.4 daily medications (SD = 6.1). Most participants reported effective communication with clinicians and pharmacists (66.9%) and expressed willingness to stop one of their medications if their clinician said it was possible (83.5%). Predictors of willingness to accept deprescribing were older age [odds ratio (OR) = 2.99, 95% confidence interval (CI) = 1.45-6.2], college/graduate degree (OR = 55.25, 95% CI = 5.74-531.4), perceiving medications as less appropriate (OR = 8.99, 95% CI = 1.1-73.62), and perceived effectiveness of communication with the clinician or pharmacist (OR = 4.56, 95% CI = 0.85-24.35). Conclusion: Adults taking ⩾3 chronic medications expressed high willingness to accept deprescribing of medications when their doctor said it was possible. Targeted strategies to facilitate communication within the patient-primary care clinician-pharmacist triad that consider patient characteristics such as age and education level may be necessary ingredients for developing successful deprescribing interventions. Plain Language Summary: Are patients willing to accept stopping medications? Sometimes, medicines that a patient takes regularly become inappropriate. In other words, the risks of adverse effects might be greater than a medicine's potential benefits. The decision to stop such medicines should involve the patient and consider their preferences. We surveyed a group of patients taking multiple medicines to see how they felt about having those medicines stopped. We also asked patients whether and how much they talk to their primary care clinician and pharmacists about their medicines. To qualify for this study, patients had to be at least 18 years old and to take three or more medicines daily; they also needed to speak English. Participants provided demographic information and answered questions about their medicines, their communication with primary care clinicians and pharmacists, and their feelings about having one or more of their medicines stopped. We recruited 107 people and were able to use responses from 103 of them. Their average age was 50 years; 65 of them identified as female, and 75 identified as White/Caucasian. Most of our participants mentioned having conversations with primary care clinicians and pharmacists and said they would be willing to stop a medication if their clinician said it was possible. Older participants, those with more years of education, those who thought their medications might lead to side effects, and those who communicated with their clinician or pharmacists were more willing to have one of their medicines stopped.Our results indicate that patient characteristics and communication with clinicians and pharmacists are factors to consider when designing interventions to reduce the use of inappropriate medicines.

One-Year Evaluation of a Targeted Medication Therapy Management Intervention for Older Adults.

BACKGROUND: Older adults are especially susceptible to adverse effects of inappropriate medication therapy, and anticholinergic medications are common culprits for cognitive dysfunction due to their action on the central nervous system. Medication therapy management (MTM) interventions can aid in deprescribing and reducing inappropriate medication use in older adults. However, there is sparse literature on the long-term sustainability of these interventions. OBJECTIVES: To (a) investigate whether the deprescribing of anticholinergic medications during an 8-week randomized controlled trial (RCT) of a targeted MTM intervention is sustained at 1-year postintervention follow-up and (b) compare anticholinergic utilization trends in the study population with a large sample of similar individuals not exposed to the intervention. METHODS: Participants in the targeted MTM (tMTM) RCT had normal cognition or mild cognitive impairment and were recruited from enrollees in a longitudinal study at the University of Kentucky Alzheimer's Disease Center (ADC) and thus have pertinent medical information gathered approximately annually. In this posttrial observational follow-up, sustainability of the anticholinergic deprescribing intervention was assessed in participants in the RCT, and anticholinergic medication use trends were described from the RCT baseline (which occurred immediately following an ADC visit) to the next annual visit in all participants. Mean change in anticholinergic burden from RCT baseline to the next annual visit was estimated using analysis of covariance, and participants were compared with 2 external samples. Anticholinergic burden was measured using the Anticholinergic Drug Scale (ADS). The odds of decreasing baseline anticholinergic burden and number of total and strong anticholinergic medications at the follow-up study time point was assessed using logistic regression. RESULTS: Of the deprescribing changes made during the initial RCT, 50% were sustained after 1 year. Participants in the tMTM trial reported decreases in the use of anticholinergic antihistamines and bladder agents (-6.5 and -4.4%, respectively), but there was no change in the use of anticholinergic agents targeted at the central nervous system. While the anticholinergic burden of RCT participants decreased over 1 year (adjusted mean ADS change [95% CI] = -0.33 [-0.72, 0.07]), it was not different than the change observed in 2 external samples at the trial center (-0.20 [-0.42, 0.02]) and nationally (-0.33 [-0.39, -0.26]). There were no statistically significant differences between trial participants and external samples in the odds of decreasing anticholinergic burden nor in decreasing the number of total, or strongly anticholinergic, medications at the 1-year follow-up. CONCLUSIONS: This study demonstrates that the sustainability of deprescribing is limited to the period of intervention, rather than affording lasting effects even over periods as short as 1 year, which was demonstrated not only in the small group of RCT participants but also by comparison with external groups. Future work should extend the duration of intervention and follow-up periods for MTM interventions to allow further insights regarding the sustainability of deprescribing efforts in older adults. DISCLOSURES: The original trial was supported by a pilot study award from the University of Kentucky Center for Clinical and Translational Sciences (UL1TR000117). Additional support for this study was provided by the National Institutes of Health/National Institute on Aging (R01 AG054130).

INtervention for Cognitive Reserve Enhancement in delaying the onset of Alzheimer's Symptomatic Expression (INCREASE), a randomized controlled trial: rationale, study design, and protocol.

BACKGROUND: The course of Alzheimer's disease (AD) includes a 10-20-year preclinical period with progressive accumulation of amyloid ß (Aß) plaques and neurofibrillary tangles in the absence of symptomatic cognitive or functional decline. The duration of this preclinical stage in part depends on the rate of pathologic progression, which is offset by compensatory mechanisms, referred to as cognitive reserve (CR). Comorbid medical conditions, psychosocial stressors, and inappropriate medication use may lower CR, hastening the onset of symptomatic AD. Here, we describe a randomized controlled trial (RCT) designed to test the efficacy of a medication therapy management (MTM) intervention to reduce inappropriate medication use, bolster cognitive reserve, and ultimately delay symptomatic AD. METHODS/DESIGN: Our study aims to enroll 90 non-demented community-dwelling adults ≥ 65 years of age. Participants will undergo positron emission tomography (PET) scans, measuring Aß levels using standardized uptake value ratios (SUVr). Participants will be randomly assigned to MTM intervention or control, stratified by Aß levels, and followed for 12 months via in-person and telephone visits. Outcomes of interest include: (1) medication appropriateness (measured with the Medication Appropriateness Index (MAI)); (2) scores from Trail Making Test B (TMTB), Montreal Cognitive Assessment (MoCA), and California Verbal Learning Test (CVLT); (3) perceived health status (measured with the SF-36). We will also evaluate pre- to post-intervention change in: (1) use of inappropriate medications as measured by MAI; 2) CR Change Score (CRCS), defined as the difference in scopolamine-challenged vs unchallenged cognitive scores at baseline and follow-up. Baseline Aß SUVr will be used to examine the relative impact of preclinical AD (pAD) pathology on CRCS, as well as the interplay of amyloid burden with inappropriate medication use. DISCUSSION: This manuscript describes the protocol of INCREASE ("INtervention for Cognitive Reserve Enhancement in delaying the onset of Alzheimer's Symptomatic Expression"): a randomized controlled trial that investigates the impact of deprescribing inappropriate medications and optimizing medication regimens on potentially delaying the onset of symptomatic AD and AD-related dementias.

Optimizing medication appropriateness in older adults: a randomized clinical interventional trial to decrease anticholinergic burden.

BACKGROUND: The complexity of medication therapy in older adults with multiple comorbidities often leads to inappropriate prescribing. Drugs with anticholinergic properties are of particular interest because many are not recognized for this property; their use may lead to increased anticholinergic burden resulting in significant health risks, as well as negatively impacting cognition. Medication therapy management (MTM) interventions showed promise in addressing inappropriate medication use, but the effectiveness of targeted multidisciplinary team interventions addressing anticholinergic medications in older populations is yet to be determined. METHODS: We conducted an 8-week, parallel-arm, randomized trial to evaluate whether a targeted patient-centered pharmacist-physician team MTM intervention ("targeted MTM intervention") reduced the use of inappropriate anticholinergic medications in older patients enrolled in a longitudinal cohort at University of Kentucky's Alzheimer's Disease Center. Study outcomes included changes in the medication appropriateness index (MAI) targeting anticholinergic medications and in the anticholinergic drug scale (ADS) score from baseline to the end of study. RESULTS: Between October 1, 2014 and September 30, 2015 we enrolled and randomized 50 participants taking at least one medication with anticholinergic properties. Of these, 35 (70%) were women, 45 (90%) were white, and 33 (66%) were cognitively intact (clinical dementia rating [CDR] = 0); mean age was 77.7 ± 6.6 years. At baseline, the mean MAI was 12.6 ± 6.3; 25 (50%) of the participants used two or more anticholinergics, and the mean ADS score was 2.8 ± 1.6. After randomization, although no statistically significant difference was noted between groups, we identified a potentially meaningful imbalance as the intervention group had more participants with intact cognition, and thus included CDR in all of the analyses. The targeted MTM intervention resulted in statistically significant CDR adjusted differences between groups with regard to improved MAI (change score of 3.6 (1.1) for the MTM group as compared with 1.0 (0.9) for the control group, p = 0.04) and ADS (change score of 1.0 (0.3) for the MTM group as compared with 0.2 (0.3) for the control group, p = 0.03). CONCLUSIONS: Our targeted MTM intervention resulted in improvement in anticholinergic medication appropriateness and reduced the use of inappropriate anticholinergic medications in older patients. Our results show promise in an area of great importance to ensure optimum outcomes for medications used in older adults. TRIAL REGISTRATION: ClinicalTrials.gov NCT02172612 . Registered 20 June 2014.
