A blueprint for success: Using an implementation framework to create a medication history technician pilot program.

BACKGROUND: Medication discrepancies at transitions of care may compromise patient safety. Trained pharmacy technicians can reduce harmful medication discrepancies at transitions of care by collecting medication histories. OBJECTIVE: We describe how to create a program integrating medication history technicians (MHTs) into the hospital discharge process using implementation science. PRACTICE DESCRIPTION: We created our MHT program at a Veterans Affairs (VA) hospital. PRACTICE INNOVATION: We used an evidence-based framework and implementation science to tailor our MHT program to meet local stakeholder needs. EVALUATION METHODS: We completed a literature review and review of current discharge practices. Then, we completed a workflow pilot, a needs assessment, and semistructured interviews with pharmacy technicians and pharmacists. We integrated these findings to identify barriers of MHT program implementation. Finally, we mapped these barriers to implementation strategies to create an MHT program implementation blueprint. RESULTS: The literature review and review of current discharge practices revealed opportunities for our program to reduce medication discrepancies. We applied these findings to our proof-of-concept workflow pilot, which reduced medication discrepancy rates at discharge. When we explored barriers in the needs assessment, we learned that 4 of 6 pharmacy technicians had some training conducting medication histories, but 5 of 6 requested additional training for the new MHT role. We explored these and additional barriers in semistructured interviews. Four themes emerged: elements of pharmacy technician training, challenges to implementation, program logistics and workflow, and pharmacy technician self-efficacy. We mapped barriers to implementation strategies to create an MHT program implementation blueprint, including developing pharmacy technician training materials, modifying our workflow, creating program evaluation materials, and strategizing how to overcome anticipated and current implementation barriers. CONCLUSIONS: We used implementation science to create a tailored MHT program. Others may adapt our implementation blueprint to fit local stakeholder needs.

Increasing anticholinergic burden and delirium in palliative care inpatients.

BACKGROUND: Delirium may complicate the hospital course and adversely impact remaining quality of life for palliative care inpatients. Medications with anticholinergic properties have been linked to delirium within elderly populations via serum anticholinergic assays. AIM: The aim of this study is to determine whether increasing anticholinergic burden, as measured using a clinical assessment tool, is associated with an increase in delirium among palliative care inpatients. DESIGN: This study was completed as a retrospective, case-control study. SETTING/PARTICIPANTS: Veterans admitted to the Veterans Affairs Boston Healthcare System and consulted to the palliative care service were considered for inclusion. Increase in anticholinergic burden from admission through hospital day 14 was assessed using the Anticholinergic Risk Scale. Presence of delirium was determined by use of a validated chart review instrument. RESULTS: A total of 217 patients were analyzed, with a mean age of 72.9 (±12.8) years. The overall delirium rate was 31% (n = 67). Patients with an increase in Anticholinergic Risk Scale (n = 72 (33%)) were 40% more likely to experience delirium (odds ratio = 1.44, 95% confidence interval = 1.07-1.94) compared to those without increase (n = 145 (67%)). After adjustment for age, brain metastasis, intensive care unit admission, illness severity, opiate use, and admission Anticholinergic Risk Scale using multivariable modeling, delirium risk remained significantly higher in patients with an Anticholinergic Risk Scale increase compared to those without increase (adjusted odds ratio = 1.43, 95% confidence interval = 1.04-1.94). CONCLUSION: An increase in Anticholinergic Risk Scale from admission was associated with delirium in palliative care inpatients. While additional study is needed, anticholinergic burden should be increased cautiously in palliative inpatients, and those with increases should be closely followed for delirium.

The anticholinergic risk scale and anticholinergic adverse effects in older persons.

BACKGROUND: Adverse effects of anticholinergic medications may contribute to events such as falls, delirium, and cognitive impairment in older patients. To further assess this risk, we developed the Anticholinergic Risk Scale (ARS), a ranked categorical list of commonly prescribed medications with anticholinergic potential. The objective of this study was to determine if the ARS score could be used to predict the risk of anticholinergic adverse effects in a geriatric evaluation and management (GEM) cohort and in a primary care cohort. METHODS: Medical records of 132 GEM patients were reviewed retrospectively for medications included on the ARS and their resultant possible anticholinergic adverse effects. Prospectively, we enrolled 117 patients, 65 years or older, in primary care clinics; performed medication reconciliation; and asked about anticholinergic adverse effects. The relationship between the ARS score and the risk of anticholinergic adverse effects was assessed using Poisson regression analysis. RESULTS: Higher ARS scores were associated with increased risk of anticholinergic adverse effects in the GEM cohort (crude relative risk [RR], 1.5; 95% confidence interval [CI], 1.3-1.8) and in the primary care cohort (crude RR, 1.9; 95% CI, 1.5-2.4). After adjustment for age and the number of medications, higher ARS scores increased the risk of anticholinergic adverse effects in the GEM cohort (adjusted RR, 1.3; 95% CI, 1.1-1.6; c statistic, 0.74) and in the primary care cohort (adjusted RR, 1.9; 95% CI, 1.5-2.5; c statistic, 0.77). CONCLUSION: Higher ARS scores are associated with statistically significantly increased risk of anticholinergic adverse effects in older patients.

The Rural PILL Program: A Postdischarge Telepharmacy Intervention for Rural Veterans.

PURPOSE: To evaluate the efficacy of the Rural Pharmacological Intervention in Late Life (PILL) program, a quality improvement initiative in which a Boston-based pharmacist provided postdischarge telepharmacy care to veterans from rural Maine. METHODS: Using an automated screening tool, we identified 100 veterans aged 65 and older who had an acute care admission to VA medical centers in Boston or Maine and were at risk of problems with medication management. The PILL pharmacist called patients the week after hospital discharge to reconcile medications, assess adherence, and identify potentially inappropriate drugs. The pharmacist worked with each veteran's family and providers to resolve problems and increase support. To determine whether the intervention decreased acute care admissions, rehospitalizations, or deaths, we matched 1 unique control to each PILL patient by age, hospital location, length of stay, admitting service, and reason for admission. Logistic regression was performed to determine the OR and 95% CI of the outcomes. RESULTS: Patients were discharged on an average of 16 medications and with 4.4 medication changes. Overall, 61% of patients had clerical errors in the discharge summary, and potential clinical concerns were identified in over 75%. Veterans who received the intervention were 70% less likely than controls to have an acute care visit at 30 days postdischarge (7 vs 20 patients; OR = 0.30; 95% CI: 0.12-0.75). There was no difference in rates of hospital readmission or mortality. CONCLUSION: This pharmacist-led phone-based program was effective in decreasing acute care utilization within 30 days after hospital discharge.

Pharmacist calls to older adults with cognitive difficulties after discharge in a Tertiary Veterans Administration Medical Center: a quality improvement program.

OBJECTIVES: To evaluate the effect of the Pharmacological Intervention in Late Life (PILL) Service, which provides pharmacist telephone follow-up after discharge of older adults from the hospital, on postdischarge acute care utilization. DESIGN: Retrospective, secondary data analysis of a quality improvement project from 2010 to 2012. SETTING: Tertiary Veterans Affairs hospital. PARTICIPANTS: Participants were inpatients aged 65 and older with delirium risk or prescribed a dementia medication (N=501, mean age 79.5±8.0; 98% male). MEASUREMENTS: PILL Service pharmacist telephone follow-up included a medication review and reconciliation within 5 days after hospital discharge. The time of the pharmacist call was examined in relation to the outcomes of emergency and urgent care encounters, readmissions, and mortality within 60 days. RESULTS: The average number of discharge medications was 14.8±5.7 with 2.8±2.2 medication changes and 1.4±1.8 discrepancies between medication order and instruction. After adjustment for age, number of medication changes, and number of discrepancies, every additional 5 minutes of pharmacist call was associated with a 15% reduction in 60-day readmission (adjusted odds ratio (OR)=0.85, 95% confidence interval (95% CI)=0.75-0.97) but was not associated with emergency or urgent care encounters (adjusted OR=1.03, 95% CI=0.91-1.17) or mortality (adjusted OR=0.84, 95% CI=0.58-1.20). CONCLUSION: Pharmacist-led medication review, reconciliation, and telephone calls after hospital discharge were associated with fewer 60-day hospital readmissions in this quality improvement program.

Improving medication management competency of clinical trainees in geriatrics.

The authors hypothesized that an interprofessional workshop would improve geriatrics trainees' medication management. The workshop was based on a needs assessment and comprised an interactive session with pharmacists on managing medications in elderly adults. Participants were trainees in their geriatrics rotation at a tertiary care medical center. Trainees completed a medication appropriateness survey for three patients, one of which was their own. After the workshop, trainees reviewed medications of the three patients. Trainees completed online surveys after their rotation and 3 months later. Of 95 trainees rotating through geriatrics, 76 (80%) attended the workshop and completed the worksheet. Trainees' scores on reviewing medication lists improved significantly, from 6.7±2.3 to 7.7±2.0 out of 11 for standardized patient 1 (P<.001) and from 5.7±1.8 to 6.4±1.5 out of 11 for standardized patient 2 (P=.009). Trainees' scores on their own patients' lists also improved significantly, from 5.6±1.5 to 6.6±1.5 out of 10 (P<.001). After the workshop, 95% (71/75) planned to change the medication regimen of the patient they presented, and 93% (68/73) planned to change other patients' medications based on information learned during the workshop. Three months later, 35% (12/34) had made changes to the regimen of the patient they discussed during the workshop, and 71% (15/21) had made changes to other patients' regimens. Seventy-eight percent (18/23) rated the workshop as the top nonclinical experience of their geriatrics rotation. In conclusion, this interprofessional medication management workshop improved trainees' ability to perform medication reviews accurately and led to change in self-reported prescribing behavior.

Aging, antiretrovirals, and adherence: a meta analysis of adherence among older HIV-infected individuals.

INTRODUCTION: Older adults are generally considered to be at greater risk for medication non-adherence due to factors such as medication complexity, side effects, cost, and cognitive decline. However, this generalization may not apply to older adults with human immunodeficiency virus (HIV). Regardless of age, suboptimal adherence to antiretroviral therapy (ART) can lead to increased viral load, immunosuppression, drug-resistant viral strains, co-morbidities, and opportunistic infections. Understanding trends of adherence to ART among older adults is critical, especially as the population of people living with HIV grows older. OBJECTIVES: The purpose of this systematic review and meta-analysis is to determine if older individuals with HIV are less likely to be non-adherent to antiretroviral therapy than younger individuals with HIV. DESIGN: A systematic search in PubMed, Embase, and PsycINFO was conducted to identify peer-reviewed articles evaluating adherence to ART in older adults. Two independent reviewers screened abstracts, applied inclusion criteria, and appraised study quality. The bibliographies of qualifying studies were searched. Data were abstracted from studies by two independent authors. Meta-analyses were conducted, and adherence levels were reported as the relative risk of non-adherence in older individuals compared to younger individuals. RESULTS: The systematic search yielded 1,848 abstracts. Twelve studies met full inclusion criteria. The overall meta-analysis found that older age reduced risk for nonadherence by 27 % (relative risk (RR) 0.72, 95 % confidence interval (CI) 0.64­0.82). Studies assessing both short-term and long-term adherence demonstrated a significant reduction in non-adherence among older patients (RR 0.75, 95 % CI 0.64­0.87 and RR 0.65, 95 % CI 0.50­0.85, respectively). CONCLUSIONS: Older adults with HIV have a reduced risk for non-adherence to ART than their younger counterparts. Future studies should seek to elucidate contributing factors of adherence among older individuals with HIV.

Delirium in palliative care patients: focus on pharmacotherapy.

Patients receiving palliative care often possess multiple risk factors and predisposing conditions for delirium. The impact of delirium on patient care in this population may also be far-reaching: affecting not only quality of remaining life but the dying process experienced by patients, caregivers, and the medical team as well. As palliative care focuses on comfort and symptom management, the approach to assessment and subsequent treatment of delirium in palliative care patients may prove difficult for providers to navigate. This article summarizes the multifactorial nature, numerous predisposing medical risk factors, neuropsychiatric adverse effects of palliative medications, pharmacokinetic changes, and challenges complicating delirium assessment and provides a systematic framework for assessment. The benefits, risks, and patient-specific considerations for treatment selection are also discussed.
