Impact of Clinical Pharmacy Specialists on the Design and Implementation of a Quality Improvement Initiative to Decrease Inappropriate Medications in a Veterans Affairs Emergency Department

Scaling the EQUIPPED medication safety program: Traditional and hub-and-spoke implementation models

BACKGROUND

The EQUIPPED (Enhancing Quality of Prescribing Practices for Older Adults Discharged from the Emergency Department) medication safety program is an evidence-informed quality improvement initiative to reduce potentially inappropriate medications (PIMs) prescribed by Emergency Department (ED) providers to adults aged 65 and older at discharge. We aimed to scale-up this successful program using (1) a traditional implementation model at an ED with a novel electronic medical record and (2) a new hub-and-spoke implementation model at three new EDs within a health system that had previously implemented EQUIPPED (hub). We hypothesized that implementation speed would increase under the hub-and-spoke model without cost to PIM reduction or site engagement.

METHODS

We evaluated the effect of the EQUIPPED program on PIMs for each ED, comparing their 12-month baseline to 12-month post-implementation period prescribing data, number of months to implement EQUIPPED, and facilitators and barriers to implementation.

RESULTS

The proportion of PIMs at all four sites declined significantly from pre- to post-EQUIPPED: at traditional site 1 from 8.9% (8.1-9.6) to 3.6% (3.6-9.6) (p < 0.001); at spread site 1 from 12.2% (11.2-13.2) to 7.1% (6.1-8.1) (p < 0.001); at spread site 2 from 11.3% (10.1-12.6) to 7.9% (6.4-8.8) (p = 0.045); and at spread site 3 from 16.2% (14.9-17.4) to 11.7% (10.3-13.0) (p < 0.001). Time to implement was equivalent at all sites across both models. Interview data, reflecting a wide scope of responsibilities for the champion at the traditional site and a narrow scope at the spoke sites, indicated disproportionate barriers to engagement at the spoke sites.

CONCLUSIONS

EQUIPPED was successfully implemented under both implementation models at four new sites during the COVID-19 pandemic, indicating the feasibility of adapting EQUIPPED to complex, real-world conditions. The hub-and-spoke model offers an effective way to scale-up EQUIPPED though a speed or quality advantage could not be shown.

A cluster-randomized trial of two implementation strategies to deliver audit and feedback in the EQUIPPED medication safety program

OBJECTIVES

The Enhancing the Quality of Prescribing Practices for Older Adults Discharged from the Emergency Department (EQUIPPED) medication safety program involves three core components including provider education, clinical decision support, and audit and feedback using the American Geriatrics Society Beers Criteria to determine potentially inappropriate medications (PIMs). This study evaluated implementation of audit and feedback through a centralized informatics-based dashboard compared to academic detailing delivered one on one by an EQUIPPED champion.

METHODS

In a cluster-randomized study (October 2019-September 2021), eight VA emergency department (EDs) implemented either the academic detailing (n = 4) or the dashboard (n = 4) strategy for the audit and feedback component of EQUIPPED. The primary outcome was the monthly proportion of PIMs prescribed to Veterans 65 years or older at ED discharge. Poisson regression was used to evaluate the proportion of PIMs prescribed 6 months prior to EQUIPPED implementation compared to 12 months following implementation.

RESULTS

Eight VA ED sites successfully implemented the EQUIPPED program. During the 6-month baseline period, the academic detailing and dashboard sites had similar PIM prescribing rates of 8.01% for academic detailing versus 8.04% for dashboard (p = 0.90). Comparing 12 months of prescribing data after EQUIPPED implementation, the academic detailing group significantly improved PIM prescribing (7.07%) compared to the dashboard group (8.10%; odds ratio 1.14, 95% confidence interval 1.08-1.22, p ≤ 0.0001). Within the groups, two of the four academic detailing sites demonstrated statistically significant reductions in PIM prescribing. One of the four dashboard sites achieved nearly 50% relative reduction in PIM prescribing.

CONCLUSIONS

Eight VA EDs successfully implemented the core components of the EQUIPPED program amid the unprecedented challenges posed by the COVID-19 pandemic. While the academic detailing approach to EQUIPPED audit and feedback was more effective at the group level to improve safe prescribing for older Veterans discharged from the ED, the trial suggests that dashboard-based audit and feedback is a reasonable strategy in resource-limited settings.

Enhancing the quality of prescribing practices for older adults discharged from the emergency department in Rhode Island

BACKGROUND

We sought to examine the effectiveness of the Enhancing the Quality of Prescribing Practices for Older Adults Discharged from the Emergency Department (EQUiPPED) medication safety program in three emergency departments (EDs) within the largest health system in Rhode Island (RI) with funding through a quality incentive payment by a private insurance partner.

METHODS

This study utilized a quasi-experimental interrupted time series design to implement EQUiPPED, a three-prong intervention aimed at reducing potentially inappropriate medication (PIM) prescriptions to 5% or less per month. We included clinicians who prescribed medications to older ED patients during the pre-and post-intervention periods from July 2018 to January 2021. We determined the monthly rate of PIM prescribing among older adults discharged from the ED, according to the American Geriatrics Society Beers Criteria, using Poisson regression.

RESULTS

247 ED clinicians (48% attendings [n = 119], 27% residents [n = 67], 25% advanced practice providers [n = 61]) were included in EQUiPPED, of which 92% prescribed a PIM during the study period. In the pre-implementation period (July 2018-July 2019) the average monthly rate of PIM prescribing was 9.30% (95% CI: 8.82%, 9.78%). In the post-implementation period (October 2019-January 2021) the PIM prescribing rate decreased significantly to 8.62% (95% CI: 8.14%, 9.10%, p < 0.01). During pre-implementation, 1325 of the 14,193 prescribed medications were considered inappropriate, while only 1108 of the 13,213 prescribed medications in post-implementation were considered inappropriate. The greatest reduction was observed among antihistamines, skeletal muscle relaxants, and benzodiazepines.

CONCLUSIONS

EQUiPPED contributed to a modest improvement in PIM prescribing to older adults among clinicians in these RI EDs even in the midst of the COVID-19 pandemic. The quality incentive funding model demonstrates a successful strategy for implementation and, with greater replication, could shape national policy regarding health care delivery and quality of care for older adults.

Effectiveness of Interventions to Reduce Potentially Inappropriate Medication in Older Patients: A Systematic Review

Background: Age-related multiple comorbidities cause older adults to be prone to the use of potentially inappropriate medicines (PIM) resulting in an increased risk of adverse events. Several strategies have emerged to support PIM prescription, and a huge number of interventions to reduce PIM have been proposed. This work aims to analyze the effectiveness of PIM interventions directed to older adults.

Methods: A systematic review was performed searching the literature in the MEDLINE PubMed, EMBASE, and Cochrane scientific databases for interventional studies that assessed the PIM interventions in older adults (≥65 years).

Results: Forty-seven articles were included, involving 52 to 124,802 patients. Various types of interventions were analyzed such as medication review, educational strategies, clinical decision support system, and organizational and multifaceted approaches. In the hospital, the most successful intervention was medication review (75.0%), while in primary care, the analysis of all included studies revealed that educational strategies were the most effective. However, the analysis of interventions that have greater evidence by its design was inconclusive.

Conclusion: The results obtained in this work suggested that PIM-setting-directed interventions should be developed to promote the wellbeing of the patients through PIM reduction. Although the data obtained suggested that medication review was the most assertive strategy to decrease the number of PIM in the hospital setting, more studies are necessary.

Process evaluation of implementation strategies to reduce potentially inappropriate medication prescribing in older population: A scoping review

OBJECTIVES

Several implementation strategies can reduce potentially inappropriate medication (PIM) prescribing. Although use of PIMs has declined in recent years, it remains prevalent. Various strategies exist to improve the appropriateness of medication use. However, little is known about the processes of these different implementation strategies. This scoping review aims to investigate how the process evaluation of implementation strategies for reducing PIM prescribing in the older population has been studied.

METHODS

We searched for process evaluations of implementation strategies for reducing PIM prescribing in PUBMED, SCOPUS and Web of Science published between January 2000 and November 2019 in English. We applied the following inclusion criteria: patients aged ≥65 years, validated PIM criteria, and implementation process evaluated. The review focuses on decision support for health care professionals. We described the findings of the process evaluations, and compared the authors' concepts of process evaluation of the included publications to those of Proctor et al.( 2010).

RESULT

Of 9131 publications screened, 29 met our inclusion criteria. Different process evaluation conceptualizations were identified. Most process evaluations took place in the initial stages of the process (acceptability, adoption, appropriateness, and feasibility) and sustainability and implementation costs were seldom evaluated. None of the included publications evaluated fidelity. Multifaceted interventions were the most studied implementation strategies. Medication review was more common in acceptability evaluations, multidisciplinary interventions in adoption evaluations, and computerized systems and educational interventions in feasibility evaluations. Process evaluations were studied from the health care professionals' viewpoint in most of the included publications, but the management viewpoint was missing.

DISCUSSION

The conceptualization of process evaluation in the field of PIM prescribing is indeterminate. There is also a current gap in the knowledge of sustainability and implementation costs. Clarifying the conceptualization of implementation process evaluation is essential in order to effectively translate research knowledge into practice.

Implementation Science to Advance Practice and Curricular Transformation: Report of the 2019-2020 AACP Research and Graduate Affairs Committee

The 2019-2020 AACP Research and Graduate Affairs Committee (RGAC) was charged with articulating the case for and evaluating the state of implementation science in academic pharmacy, given the potential for implementation science to act as a driver of practice and curricular transformation. Based on the current state of pharmacy research in this area, the RGAC was further charged with outlining a plan to raise the profile of implementation science with pharmacy leadership and defining strategies for AACP to facilitate schools in applying its methods to their practice and education missions. For this work, the RGAC considered implementation science to be the scientific study of methods and strategies to promote adoption of evidence-based practices and interventions into real world settings and routine practice, to improve the quality and effectiveness of services. The RGAC identified three components of an effective strategy for AACP to assist schools in applying implementation science in practice and education: 1) raising awareness of implementation science as an opportunity for academic pharmacy, 2) connecting pharmacy researchers with the larger implementation science community, and 3) developing pharmacy researchers in the competencies and methods associated with implementation science. Specific recommendations for this strategy were informed by searches of the literature and funding landscape related to implementation science and pharmacy. The RGAC also identified stakeholder groups that AACP could target in a campaign to raise awareness of implementation science and connectivity to the existing research community in this space, including academic leadership, faculty with expertise in relevant research methodologies (eg, the Social and Administrative Science (SAS) section of AACP), and the academic pharmacy community as a whole.

Exploring how pharmacists engage with patients about over-the-counter medications

OBJECTIVE

This study used an innovative information-gathering approach to provide insight into the nature and structure of pharmacy staff encounters with patients seeking over-the-counter (OTC) medications and revealed specific activities of pharmacy staff around these encounters.

METHODS

A multistep process was used to develop and standardize an 8-item OTC Encounter Form to document the characteristics of pharmacy staff-patient encounters. The OTC Form contained several domains, including topics discussed and the problems or symptoms identified during the encounter, staff functions during the encounter, and approximate time spent with the patient. Nine pharmacists and 8 technicians used the OTC Form to document patient encounters over 7 consecutive days. Frequency distributions for each OTC Form item are reported.

RESULTS

One hundred eleven OTC Forms were completed. Adults aged 65 years or older were involved in 46% of all encounters. Pharmacists provided the only assistance in 41% of encounters and worked in partnership with other pharmacy staff for another 25% of encounters. Many encounters required the pharmacy staff to leave the prescription department, involved discussions about a variety of problems or symptoms, and lasted less than 3 minutes. Although the most prevalent encounter topic was locations of a particular product, about one-third of encounters involved either recommendations about a product or providing information about a product, and 41% involved communications about 2 or more topics. Finally, 11% of encounters generated a nondrug recommendation, and 8% resulted in a referral to a physician.

CONCLUSION

Pharmacists play a key role in ensuring that the benefits of OTC medications outweigh the risks, thereby providing an important resource for patient engagement about safe medication selection and use. Examining the features of OTC encounters creates an evidence base to promote best practices for OTC encounters, increasing pharmacists' ability to help people, especially older adults, navigate the intricacies of OTC medication use, without significantly increasing pharmacy staff workload.

Interventions to improve the appropriate use of polypharmacy for older people

BACKGROUND

Inappropriate polypharmacy is a particular concern in older people and is associated with negative health outcomes. Choosing the best interventions to improve appropriate polypharmacy is a priority, hence interest in appropriate polypharmacy, where many medicines may be used to achieve better clinical outcomes for patients, is growing. This is the second update of this Cochrane Review.

OBJECTIVES

To determine which interventions, alone or in combination, are effective in improving the appropriate use of polypharmacy and reducing medication-related problems in older people.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers up until 7 February 2018, together with handsearching of reference lists to identify additional studies.

SELECTION CRITERIA

We included randomised trials, non-randomised trials, controlled before-after studies, and interrupted time series. Eligible studies described interventions affecting prescribing aimed at improving appropriate polypharmacy in people aged 65 years and older, prescribed polypharmacy (four or more medicines), which used a validated tool to assess prescribing appropriateness. These tools can be classified as either implicit tools (judgement-based/based on expert professional judgement) or explicit tools (criterion-based, comprising lists of drugs to be avoided in older people).

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed abstracts of eligible studies, extracted data and assessed risk of bias of included studies. We pooled study-specific estimates, and used a random-effects model to yield summary estimates of effect and 95% confidence intervals (CIs). We assessed the overall certainty of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We identified 32 studies, 20 from this update. Included studies consisted of 18 randomised trials, 10 cluster randomised trials (one of which was a stepped-wedge design), two non-randomised trials and two controlled before-after studies. One intervention consisted of computerised decision support (CDS); and 31 were complex, multi-faceted pharmaceutical-care based approaches (i.e. the responsible provision of medicines to improve patient's outcomes), one of which incorporated a CDS component as part of their multi-faceted intervention. Interventions were provided in a variety of settings. Interventions were delivered by healthcare professionals such as general physicians, pharmacists and geriatricians, and all were conducted in high-income countries. Assessments using the Cochrane 'Risk of bias' tool, found that there was a high and/or unclear risk of bias across a number of domains. Based on the GRADE approach, the overall certainty of evidence for each pooled outcome ranged from low to very low.It is uncertain whether pharmaceutical care improves medication appropriateness (as measured by an implicit tool), mean difference (MD) -4.76, 95% CI -9.20 to -0.33; 5 studies, N = 517; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the number of potentially inappropriate medications (PIMs), (standardised mean difference (SMD) -0.22, 95% CI -0.38 to -0.05; 7 studies; N = 1832; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PIMs, (risk ratio (RR) 0.79, 95% CI 0.61 to 1.02; 11 studies; N = 3079; very low-certainty evidence). Pharmaceutical care may slightly reduce the number of potential prescribing omissions (PPOs) (SMD -0.81, 95% CI -0.98 to -0.64; 2 studies; N = 569; low-certainty evidence), however it must be noted that this effect estimate is based on only two studies, which had serious limitations in terms of risk bias. Likewise, it is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PPOs (RR 0.40, 95% CI 0.18 to 0.85; 5 studies; N = 1310; very low-certainty evidence). Pharmaceutical care may make little or no difference in hospital admissions (data not pooled; 12 studies; N = 4052; low-certainty evidence). Pharmaceutical care may make little or no difference in quality of life (data not pooled; 12 studies; N = 3211; low-certainty evidence). Medication-related problems were reported in eight studies (N = 10,087) using different terms (e.g. adverse drug reactions, drug-drug interactions). No consistent intervention effect on medication-related problems was noted across studies.

AUTHORS' CONCLUSIONS

It is unclear whether interventions to improve appropriate polypharmacy, such as reviews of patients' prescriptions, resulted in clinically significant improvement; however, they may be slightly beneficial in terms of reducing potential prescribing omissions (PPOs); but this effect estimate is based on only two studies, which had serious limitations in terms of risk bias.

Hypoglycemia Associated With Insulin Use During Treatment of Hyperkalemia Among Emergency Department Patients

Purpose: Hypoglycemia is a common adverse event associated with insulin during treatment of hyperkalemia in hospitalized patients; however, limited data exist regarding hypoglycemia incidence and appropriate dosing strategies for treatment of patients in the emergency department. The study objective was to determine the incidence of hypoglycemia associated with insulin use during treatment of hyperkalemia among patients seen in the emergency department. Methods: This was an Institutional Review Board (IRB)-approved retrospective, chart-review study. All adult patients who received intravenous regular insulin as a result of an order from the emergency department hyperkalemia order set were eligible for inclusion. The main clinical outcomes were incidence of hypoglycemia (blood glucose <70 mg/dL) and severe hypoglycemia (blood glucose <40 mg/dL). Blood glucose was checked within 24 hours of insulin administration. Results: A total of 172 patients were included. The incidence of hypoglycemia was 19.8% (n = 34) and the incidence of severe hypoglycemia was 5.2% (n = 9). Hypoglycemic patients had a significantly lower median blood glucose at baseline compared to those who did not develop hypoglycemia (83.5 [72.0-112.0] mg/dL vs 123.0 [96.0-167.0] mg/dL, P < .0001); however, no difference was noted between groups in the average insulin dose administered (0.11 ± 0.04 units/kg vs 0.12 ± 0.05 units/kg, P = .6175). Conclusion: There is a concerning risk of hypoglycemia associated with insulin use during treatment of hyperkalemia in the emergency department. Standard insulin doses may not be appropriate in some cases like patients with lower baseline blood glucose. Further research is warranted to develop safer hyperkalemia treatment protocols that mitigate this high risk of hypoglycemia associated with insulin use.

An Interdisciplinary Academic Detailing Approach to Decrease Inappropriate Medication Prescribing by Physician Residents for Older Veterans Treated in the Emergency Department

OBJECTIVE

To evaluate the impact of an academic detailing intervention delivered as part of a quality improvement project by a physician-pharmacist pair on (1) self-reported confidence in prescribing for older adults and (2) rates of potentially inappropriate medications (PIMs) prescribed to older adults by physician residents in a Veteran Affairs emergency department (ED).

METHODS

This quality improvement project at a single site utilized a questionnaire that assessed knowledge of Beers Criteria, self-perceived barriers to appropriate prescribing in older adults, and self-rated confidence in ability to prescribe in older adults which was administered to physician residents before and after academic detailing delivered during their emergency medicine rotation. PIM rates in the resident cohort who received the academic detailing were compared to residents who did not receive the intervention.

RESULTS

Sixty-three residents received the intervention between February 2013 and December 2014. At baseline, approximately 50% of the residents surveyed reported never hearing about nor using the Beers Criteria. A significantly greater proportion of residents agreed or strongly agreed in their abilities to identify drug-disease interactions and to prescribe the appropriate medication for the older adult after receiving the intervention. The resident cohort who received the educational intervention was less likely to prescribe a PIM when compared to the untrained resident cohort with a rate ratio of 0.73 ( P < .0001).

CONCLUSION

Academic detailing led by a physician-pharmacist pair resulted in improved confidence in physician residents' ability to prescribe safely in an older adult ED population and was associated with a statistically significant decrease in PIM rates.

Effectiveness of a Clinical Pharmacist Medication Therapy Management Program in Discontinuation of Drugs to Avoid in the Elderly

BACKGROUND

Despite evidence of fall risk associated with some drugs to avoid in the elderly (DAEs), many aged patients continue to receive them.

OBJECTIVE

To assess the effectiveness of a clinical pharmacist medication therapy management program (MTM) on discontinuation of prescribed DAEs.

METHODS

This was a retrospective cohort study conducted at an integrated health care delivery system. Kaiser Permanente Colorado beneficiaries aged ≥65 years who were MTM-eligible and targeted for a DAE dispensing between 01/01/2015 and 09/30/2015 were included in the observation group. Medicare beneficiaries who were not eligible for MTM but had a targeted DAE dispensing during the same time period were included in the control group. The percentage of patients with another DAE dispensing of the same specified medication (no matter the strength) during the 100 days following index DAE dispensing was assessed. Univariate and multivariable logistic regression analyses were conducted.

RESULTS

A total of 9,059 Medicare beneficiaries were included, with 226 beneficiaries in the MTM group and 8,833 beneficiaries in the non-MTM group. Beneficiaries were primarily female and white and had a high burden of chronic disease. The percentages of patients with another dispensing of the specified DAE were 7.1% (95% CI = 3.7%-10.4%) for the MTM beneficiaries and 35.3% (95% CI 34.2%-36.2%) for the non-MTM beneficiaries (P < 0.001). The OR for the MTM group to have received another dispensing of the specified DAE was 0.12 (95% CI = 0.08-0.22) with adjustment for potential confounders.

CONCLUSIONS

A clinical pharmacist-provided MTM intervention was associated with decreased DAE dispensing in Medicare beneficiaries. Future studies should evaluate means to further decrease DAE use in the aged.
