"Positive Kidney Health": Implementation and design of a pharmacist-led intervention for patients at risk for development or progression of chronic kidney disease.

BACKGROUND: Patients with early chronic kidney disease (CKD) or underlying risk factors are often unaware of their kidney test results, common causes of CKD, and ways to lower risk of disease onset/progression. OBJECTIVE: To test feasibility of a pharmacist-led intervention targeting patient education and risk factors in patients with early CKD and those at risk for CKD. PRACTICE DESCRIPTION: Ambulatory care pharmacists in community-based primary care clinics delivered kidney health education, ordered labs, and recommended medication adjustments. PRACTICE INNOVATION: We identified patients with a moderate rate of decline (≥2 mL/min/1.73 m2 per year) in estimated glomerular filtration (eGFR) at-risk for CKD or early stage CKD. An interactive workbook was designed to teach patients about kidney test results and self-management of risk factors including hypertension, type 2 diabetes, cigarette smoking, and chronic oral nonsteroidal anti-inflammatory drug use. EVALUATION METHODS: Outcomes included visit uptake, completion of annual albuminuria screening, and initiation of guideline-directed medications for CKD. Patients were surveyed pre- and post-intervention for kidney health knowledge and perceptions regarding pharmacist-provided information. RESULTS: Our sample of 20 participants had a mean eGFR of 59 mL/min/1.73 m2 and the mean eGFR decline was -4.6 mL/min/1.73 m2 per year. There were 47 visits during the pilot period from February 2021 to October 2021. Thirteen patients were missing albuminuria screening within 12 months; 2 of 9 patients with resulting labs had new microalbuminuria and were started on renoprotective medications. Patients had improved understanding of their kidney function test results and most did not consider the information scary or confusing. CONCLUSION: Barriers to enrollment included fewer participants with multiple risk factors for CKD. The pharmacists were able to engage patients in learning the importance of monitoring and self-management of kidney health. A collaborative practice agreement may enhance a similar intervention that includes initiation of renoprotective medications.

Differences in Weight Loss by Race and Ethnicity in the PRIDE Trial: a Qualitative Analysis of Participant Perspectives.

BACKGROUND: Many Diabetes Prevention Program (DPP) translation efforts have been less effective for underresourced populations. In the cluster-randomized Prediabetes Informed Decision and Education (PRIDE) trial, which evaluated a shared decision-making (SDM) intervention for diabetes prevention, Hispanic and non-Hispanic Black participants lost less weight than non-Hispanic White participants at 12-month follow-up. OBJECTIVE: To explore perspectives about weight loss from PRIDE participants of different racial and ethnic groups. PARTICIPANTS: Sample of participants with prediabetes who were randomized to the PRIDE intervention arm (n=24). APPROACH: We conducted semi-structured interviews within three groups stratified by DPP participation and % weight loss at 12 months: (DPP+/WL+, enrolled in DPP and lost >5% weight; DPP+/WL-, enrolled in DPP and lost <3% weight; DPP-/WL-, did not enroll in DPP and lost <3% weight). Each group was further subdivided on race and ethnicity (non-Hispanic Black (NHB), non-Hispanic White (NHW), Hispanic). Interviews were conducted on Zoom and transcripts were coded and analyzed with Dedoose. KEY RESULTS: Compared to NHW participants, Hispanic and NHB participants more often endorsed weight loss barriers of limited time to make lifestyle changes due to long work and commute hours, inconvenient DPP class locations and offerings, and limited disposable income for extra weight loss activities. Conversely, facilitators of weight loss regardless of race and ethnicity included retirement or having flexible work schedules; being able to identify convenient DPP classes; having a strong, positive support system; and purchasing supplementary resources to support lifestyle change (e.g., gym memberships, one-on-one activity classes). CONCLUSIONS: We found that NHB and Hispanic SDM participants report certain barriers to weight loss more commonly than NHW participants, particularly barriers related to limited disposable income and/or time constraints. Our findings suggest that increased lifestyle change support and flexible program delivery options may be needed to ensure equity in DPP reach, participant engagement, and outcomes.

Reducing Emergency Department Visits Among Patients With Diabetes by Embedding Clinical Pharmacists in the Primary Care Teams.

BACKGROUND: Pharmacists are effective at improving control of cardiovascular risk factors, but it less clear whether these improvements translate into less emergency department (ED) use and fewer hospitalizations. The UCMyRx program embed pharmacists in primary care. OBJECTIVE: The objective of this study was to examine if the integration of pharmacists into primary care was associated with lower ED and hospital use for patients with diabetes. DESIGN: This was a quasi-experimental study with a comparator group. SUBJECTS: The analytic sample included patients with diabetes with uncontrolled cardiovascular risk factors (A1C >9%, blood pressure >140/90 mm Hg, low-density lipoprotein-cholesterol >130 mg/dL) who had 1 or more visits in either a UCMyRx (648 patients, 14 practices) or usual care practice (1944 patients, 14 practices). MEASURES: Our outcomes were ED and hospitalization rates as measured before and after the consultations between UCMyRx and usual care. Our predictor variable was the pharmacist consultation. Poisson generalized estimating equations model was used to estimate the adjusted predicted change in utilization before and after the pharmacist consultation. The Average Treatment Effect on the Treated was estimated. RESULTS: In models adjusted, the adjusted mean predicted number of emergency department visits/month during the year before the consultation was 0.09 among UCMyRx patients. During the year after initiating the care with the pharmacists, this rate decreased to an adjusted mean monthly rate of 0.07, with an Average Treatment Effect on the Treated=0.021 (P=0.035), a predicted reduction of 21% in emergency department visits associated with the clinical pharmacist consults. There was a nonsignificant predicted 3.2% reduction in hospitalizations over time for patients in the UCMyRx program. CONCLUSION: Clinical pharmacists are an important addition to clinical care teams in primary care practices and significantly decreased utilization of the ED among patients with poorly controlled diabetes.

Potential savings associated with drug substitution in Medicare Part D: the Translating Research into Action for Diabetes (TRIAD) study.

BACKGROUND: Drug substitution is a promising approach to reducing medication costs. OBJECTIVE: To calculate the potential savings in a Medicare Part D plan from generic or therapeutic substitution for commonly prescribed drugs. DESIGN: Cross-sectional, simulation analysis. PARTICIPANTS: Low-income subsidy (LIS) beneficiaries (n = 145,056) and non low-income subsidy (non-LIS) beneficiaries (n = 1,040,030) enrolled in a large, national Part D health insurer in 2007 and eligible for a possible substitution. MEASUREMENTS: Using administrative data from 2007, we identified claims filled for brand-name drugs for which a direct generic substitute was available. We also identified the 50 highest cost drugs separately for LIS and non-LIS beneficiaries, and reached consensus on which drugs had possible therapeutic substitutes (27 for LIS, 30 for non-LIS). For each possible substitution, we used average daily costs of the original and substitute drugs to calculate the potential out-of-pocket savings, health plan savings, and when applicable, savings for the government/LIS subsidy. RESULTS: Overall, 39 % of LIS beneficiaries and 51 % of non-LIS beneficiaries were eligible for a generic and/or therapeutic substitution. Generic substitutions resulted in an average annual savings of $160 in the case of LIS beneficiaries and $127 in the case of non-LIS beneficiaries. Therapeutic substitutions resulted in an average annual savings of $452 in the case of LIS beneficiaries and $389 in the case of non-LIS beneficiaries. CONCLUSIONS: Our findings indicate that drug substitution, particularly therapeutic substitution, could result in significant cost savings. There is a need for additional studies evaluating the acceptability of therapeutic substitution interventions within Medicare Part D.

The Effectiveness of Shared Decision-making for Diabetes Prevention: 24- and 36-Month Results From the Prediabetes Informed Decision and Education (PRIDE) Trial.

OBJECTIVE: We conducted a cluster-randomized, shared decision-making (SDM) trial offering lifestyle change, metformin, or both options, to adults at risk for diabetes in a primary care network (n = 20 practices). RESEARCH DESIGN AND METHODS: We used propensity score matching to identify control patients and used electronic health record data to compare weight loss at 24 and 36 months of follow-up and diabetes incidence at 36 months of follow-up. RESULTS: In adjusted post hoc analyses, SDM participants (n = 489) maintained modestly greater 24-month weight loss of -3.1 lb and 36-month weight loss of -2.7 lb versus controls (n = 1,430, both comparisons P < 0.001). SDM participants who chose both lifestyle change and metformin sustained weight loss at 36 months of -4.1 lb (P < 0.001 vs. controls). We found no differences in incident diabetes (15% of SDM participants, 14% of control participants; P = 0.64). CONCLUSIONS: This is one of the first studies to demonstrate weight loss maintenance up to 36 months after diabetes prevention SDM.

Primary care provider adherence to an alert for intensification of diabetes blood pressure medications before and after the addition of a "chart closure" hard stop.

Objective: To evaluate provider responses to a narrowly targeted "Best Practice Advisory" (BPA) alert for the intensification of blood pressure medications for persons with diabetes before and after implementation of a "chart closure" hard stop, which is non-interruptive but demands an action or dismissal before the chart can be closed. Materials and Methods: We designed a BPA that fired alerts within an electronic health record (EHR) system during outpatient encounters for patients with diabetes when they had elevated blood pressures and were not on angiotensin receptor blocking medications. The BPA alerts were implemented in eight primary care practices within UCLA Health. We compared data on provider responses to the alerts before and after implementing a "chart closure" hard stop, and we conducted chart reviews to adjudicate each alert's appropriateness. Results: Providers responded to alerts more often after the "chart closure" hard stop was implemented (P < .001). Among 284 alert firings over 16 months, we judged 107 (37.7%) to be clinically unnecessary or inappropriate based on chart review. Among the remainder, which represent clear opportunities for treatment, providers ordered the indicated medication more often (41% vs 75%) after the "chart closure" hard stop was implemented (P = .001). Discussion: The BPA alerts for diabetes and blood pressure control achieved relatively high specificity. The "chart closure" hard stop improved provider attention to the alerts and was effective at getting patients treated when they needed it. Conclusion: Targeting specific omitted medication classes can produce relatively specific alerts that may reduce alert fatigue, and using a "chart closure" hard stop may prompt providers to take action without excessively disrupting their workflow.
