Clinical Decision Support and Optional Point of Care Testing of Renal Function for Safe Use of Antibiotics in Elderly Patients: A Retrospective Study in Community Pharmacy Practice

Improvement in Pharmacy Student Responses to Medication-Related Problems with and without Clinical Decision Support Alerts

OBJECTIVE

To assess pharmacy student responses to medication problems with and without clinical decision support (CDS) alerts during simulated order verification.

METHODS

Three classes of students completed an order verification simulation. The simulation randomized students to a different series of 10 orders with varying CDS alert frequency. Two of the orders contained medication-related problems. The appropriateness of the students' interventions and responses to the CDS alerts were evaluated. In the following semester for 2 classes, 2 similar simulations were completed. All 3 simulations contained 1 problem with and 1 without an alert.

RESULTS

During the first simulation, 384 students reviewed an order with a problem and an alert. Students exposed to prior inappropriate alerts within the simulation had less appropriate responses (66% vs 75%). Of 321 students who viewed a second order with a problem, those reviewing an order lacking an alert recommended an appropriate change less often (45% vs 87%). Among 351 students completing the second simulation, those who participated in the first simulation appropriately responded to the alert for a problem more often than those who only received a didactic debrief (95% vs 87%). Among those completing all 3 simulations, appropriate responses increased between simulations for problems with (n = 238, 72-95-93%) and without alerts (n = 49, 53-71-90%).

CONCLUSIONS

Some pharmacy students displayed baseline alert fatigue and overreliance on CDS alerts for medication problem detection during order verification simulations. Exposure to the simulations improved CDS alert response appropriateness and detection of problems.

Effects and characteristics of clinical decision support systems on the outcomes of patients with kidney disease: a systematic review

OBJECTIVES

This systematic review was conducted to investigate the characteristics and effects of clinical decision support systems (CDSSs) on clinical and process-of-care outcomes of patients with kidney disease.

METHODS

A comprehensive systematic search was conducted in electronic databases to identify relevant studies published until November 2020. Randomized clinical trials evaluating the effects of using electronic CDSS on at least one clinical or process-of-care outcome in patients with kidney disease were included in this study. The characteristics of the included studies, features of CDSSs, and effects of the interventions on the outcomes were extracted. Studies were appraised for quality using the Cochrane risk-of-bias assessment tool.

RESULTS

Out of 8722 retrieved records, 11 eligible studies measured 32 outcomes, including 10 clinical outcomes and 22 process-of-care outcomes. The effects of CDSSs on 45.5% of the process-of-care outcomes were statistically significant, and all the clinical outcomes were not statistically significant. Medication-related process-of-care outcomes were the most frequently measured (54.5%), and CDSSs had the most effective and positive effect on medication appropriateness (18.2%). The characteristics of CDSSs investigated in the included studies comprised automatic data entry, real-time feedback, providing recommendations, and CDSS integration with the Computerized Provider Order Entry system.

CONCLUSION

Although CDSS may potentially be able to improve processes of care for patients with kidney disease, particularly with regard to medication appropriateness, no evidence was found that CDSS affects clinical outcomes in these patients. Further research is thus required to determine the effects of CDSSs on clinical outcomes in patients with kidney diseases.

Evaluation of Point-of-Care Testing in Pharmacy to Inform Policy Writing by the New Brunswick College of Pharmacists

Pharmacy practice continues to advance, allowing professionals to contribute further to patient care and the healthcare system. Pharmacists are authorized to perform point-of-care testing (POCT) in seven out of ten Canadian provinces. In considering the potential for enhanced clinical decision-making with the opportunity to gain patient data at the site of care, the New Brunswick College of Pharmacists (NBCP) proceeded to draft regulatory amendments and a policy to enable POCT scope in New Brunswick. Policy writing is a core function of Provincial Regulatory Authorities in Canada as the process determines principles that direct pharmacy practice. Each province has a differing scope of practice and method for developing documents. This paper highlights the approach, analysis, and findings of the NBCP pursuant to drafting a POCT policy. The policy development process included a literature search and environmental scan of the ten Canadian provincial regulatory authorities along with other countries. The findings highlighted in this paper describe the use of POCT, quality assurance, regulatory framework, educational opportunities, and the role of pharmacy technicians in relation to POCT in a pharmacy setting. The approach NBCP took to engage professionals and decisions on the direction of the policy are described. As point-of-care services continue to expand in pharmacies, the insights by the NBCP can be utilized by other regulatory bodies or pharmacy professionals who are implementing or enhancing POCT policies or procedures within their organizations.

Clinical Nudge Impact on Herpes Zoster Vaccine Series Completion in Pharmacies

INTRODUCTION

A new recombinant herpes zoster vaccine has advanced efforts to prevent shingles, but its multidose regimen introduces potential barriers to full protection that must be managed by community pharmacies. To address this potential patient management challenge, a pharmacy records clinical support tool was implemented to assist pharmacy staff in managing herpes zoster vaccine dose completion.

METHODS

Beginning in November 2018, a large community pharmacy chain (operating in 36 states) implemented a provider nudge within its clinical decision support tool across all locations that fit seamlessly into the existing workflow, alerting the pharmacy staff of the need for a patient's second dose. Initial and second doses were followed over 2 overlapping, 10-month periods before and after system launch. Differences in vaccine completion rates before and after the system was operational were assessed by chi-square tests and predictors of completion, controlling for store- and patient-level characteristics, and were analyzed by multivariable logistic regression and generalized linear models throughout 2021.

RESULTS

Across 2,271 pharmacies, 71,459 and 41,982 initial doses of the herpes zoster vaccine were given in the baseline and intervention period, respectively. The proportion of patients completing both doses increased slightly after system implementation (before: 71.9%, after: 75.2%; p<0.0001). However, dramatic improvements in time to dose completion were observed (before: 109.8 days, after: 93.3 days; p<0.001), and changes were significant in stores in all but 4 states.

CONCLUSIONS

Results suggest that the use of a clinical nudge improved the occurrence of and time to herpes zoster vaccine dose completion in adults across the U.S.

Dose Optimization of Colistin: A Systematic Review

Colistin is considered a last treatment option for multi-drug and extensively resistant Gram-negative infections. We aimed to assess the available data on the dosing strategy of colistin. A systematic review was performed to identify all published studies on the dose optimization of colistin. Grey literature and electronic databases were searched. Data were collected in a specified form and the quality of the included articles was then assessed using the Newcastle-Ottawa scale for cohort studies, the Cochrane bias tool for randomized clinical trials (RCT), and the Joanna Briggs Institute (JBI) critical checklist for case reports. A total of 19 studies were included, of which 16 were cohort studies, one was a RCT, and two were case reports. A total of 18 studies proposed a dosing regimen for adults, while only one study proposed a dosing schedule for pediatric populations. As per the available evidence, a loading dose of 9 million international units (MIU) of colistin followed by a maintenance dose of 4.5 MIU every 12 h was considered the most appropriate dosing strategy to optimize the safety and efficacy of treatment and improve clinical outcomes. This review supports the administration of a loading dose followed by a maintenance dose of colistin in severe and life-threatening multi-drug Gram-negative bacterial infections.

Scoping review exploring the impact of digital systems on processes and outcomes in the care management of acute kidney injury and progress towards establishing learning healthcare systems

OBJECTIVES

Digital systems have long been used to improve the quality and safety of care when managing acute kidney injury (AKI). The availability of digitised clinical data can also turn organisations and their networks into learning healthcare systems (LHSs) if used across all levels of health and care. This review explores the impact of digital systems i.e. on patients with AKI care, to gauge progress towards establishing LHSs and to identify existing gaps in the research.

METHODS

Embase, PubMed, MEDLINE, Cochrane, Scopus and Web of Science databases were searched. Studies of real-time or near real-time digital AKI management systems which reported process and outcome measures were included.

RESULTS

Thematic analysis of 43 studies showed that most interventions used real-time serum creatinine levels to trigger responses to enable risk prediction, early recognition of AKI or harm prevention by individual clinicians (micro level) or specialist teams (meso level). Interventions at system (macro level) were rare. There was limited evidence of change in outcomes.

DISCUSSION

While the benefits of real-time digital clinical data at micro level for AKI management have been evident for some time, their application at meso and macro levels is emergent therefore limiting progress towards establishing LHSs. Lack of progress is due to digital maturity, system design, human factors and policy levers.

CONCLUSION

Future approaches need to harness the potential of interoperability, data analytical advances and include multiple stakeholder perspectives to develop effective digital LHSs in order to gain benefits across the system.

Point-of-care testing in pharmacies-An evaluation of the service from the lens of resource-based theory of competitive advantage

BACKGROUND

Point-of-care tests (POCTs) are innovative services that are increasingly offered in community pharmacies. Assessments of these services should consider their financial sustainability in addition to their effectiveness if they are to be successful over time in a competitive environment.

OBJECTIVES

The aim of this research was to review and evaluate the POCT practice innovations literature through the lens of the resource-based theory (RBT) of competitive advantage.

DATA SOURCES

Articles describing POCT services were identified systematically through PubMed, exclusively.

STUDY SELECTION

All POCT articles in the review met the following inclusion criteria: (1) articles were published after 1999; (2) interventions were pharmacist-led innovations within a community pharmacy; (3) articles described research studies with results; and (4) articles were published in English, Spanish, or Portuguese.

DATA EXTRACTION

The RBT was operationalized using a strengths, weaknesses, opportunities, threats matrix and a business model canvas, which were employed to extract and analyze data. Articles were assessed according to the degree to which they articulated elements that the RBT needed to assess their financial sustainability in targeted markets.

RESULTS

A total of 36 articles describing POCTs and associated services were included in this review. Most of the studies reported aspects pertaining to the contextual environment of the innovation, value proposition, key activities, partners, and channels of distribution. However, the competitive dimension of the environment, as well as the cost structure and revenue streams, were often neglected in the studies.

CONCLUSIONS

The RBT is a widely tested framework that can be used for planning and reporting POCT practice innovations. On the basis of this framework, pharmacists seem to do a good job in describing how to provide POCT but fall short in explaining how these services are sustainable over time.

Exploring the early phase of implementation of a vaccine-based clinical decision support system in the community pharmacy

OBJECTIVE

To explore the implementation strategy of a recombinant zoster vaccine (RZV) clinical decision support (CDS) intervention in community pharmacy workflow to increase second-dose vaccination rates.

SETTING

The level of analysis was the unit (e.g., pharmacy). The participants were selected from across approximately 2200 pharmacies in 37 states on the basis of criteria believed to affect implementation success (e.g., size, location) using a sampling matrix.

PRACTICE DESCRIPTION

Large supermarket pharmacy chain.

PRACTICE INNOVATION

Vaccine-based CDS intervention in community pharmacy workflow.

EVALUATION

A mixed-methods contextual inquiry approach explored the implementation of a new RZV CDS workflow intervention. Data collection involved key informant, semistructured interviews and an electronic, Web-based survey. The survey was based on a validated instrument and was made available to all pharmacists nationwide within the study organization to assess views of the implementation's appropriateness, acceptability, and feasibility during early implementation. Afterward, a series of semistructured, in-depth interviews were conducted until a point of saturation was reached. The interview guide was based on selected constructs of the Consolidated Framework for Implementation Research.

RESULTS

A total of 1128 survey responses were collected. Survey respondents agreed or strongly agreed that the implementation was acceptable (78.34%), appropriate (79.92%), and feasible (80.53%). Twelve pharmacist participants were interviewed via telephone. Five themes emerged from the interviews, revealing facilitators and barriers that affected implementation of the intervention: intervention characteristics, outer setting, inner setting, characteristics of individuals, and process.

CONCLUSION

The implementation of the RZV CDS "nudge" intervention was welcomed, suitable, and operable in the community pharmacy setting to meet the needs of the organization, employees, and patients. The contextual factors identified during the implementation process of this CDS intervention in a community pharmacy setting may be used in scaling this and future CDS interventions for public health initiatives aimed at pharmacists in this setting.

Merits, features, and desiderata to be considered when developing electronic health records with embedded clinical decision support systems in Palestinian hospitals: a consensus study

BACKGROUND

Electronic health records (EHRs) with embedded clinical decision support systems (CDSSs) have the potential to improve healthcare delivery. This study was conducted to explore merits, features, and desiderata to be considered when planning for, designing, developing, implementing, piloting, evaluating, maintaining, upgrading, and/or using EHRs with CDSSs.

METHODS

A mixed-method combining the Delphi technique and Analytic Hierarchy Process was used. Potentially important items were collected after a thorough search of the literature and from interviews with key contact experts (n = 19). Opinions and views of the 76 panelists on the use of EHRs were also explored. Iterative Delphi rounds were conducted to achieve consensus on 122 potentially important items by a panel of 76 participants. Items on which consensus was achieved were ranked in the order of their importance using the Analytic Hierarchy Process.

RESULTS

Of the 122 potentially important items presented to the panelists in the Delphi rounds, consensus was achieved on 110 (90.2%) items. Of these, 16 (14.5%) items were related to the demographic characteristics of the patient, 16 (14.5%) were related to prescribing medications, 16 (14.5%) were related to checking prescriptions and alerts, 14 (12.7%) items were related to the patient's identity, 13 (11.8%) items were related to patient assessment, 12 (10.9%) items were related to the quality of alerts, 11 (10%) items were related to admission and discharge of the patient, 9 (8.2%) items were general features, and 3 (2.7%) items were related to diseases and making diagnosis.

CONCLUSIONS

In this study, merits, features, and desiderata to be considered when planning for, designing, developing, implementing, piloting, evaluating, maintaining, upgrading, and/or using EHRs with CDSSs were explored. Considering items on which consensus was achieved might promote congruence and safe use of EHRs. Further studies are still needed to determine if these recommendations can improve patient safety and outcomes in Palestinian hospitals.

Budget Impact Analysis of a Renal Point-of-Care Test in Dutch Community Pharmacies to Prevent Antibiotic-Related Hospitalizations

OBJECTIVES

Medication errors that lead to adverse drug reactions are a key cause of unintentional patient harm and subsequent economic burden. To prevent this, measurement of renal function could be considered. The aim of this study was to determine the budget impact of obtaining and evaluating renal function in community pharmacies in the Netherlands to prevent antibiotic-related hospitalizations.

METHODS

A decision model was built to simulate the process of antibiotic prescriptions in community pharmacies with and without the use of a point-of-care test (PoCT) in patients aged 65 years and older. By using a PoCT, the number of patients with renal function values available increases, leading to the possibility of dose adjustment when necessary. In turn, this might avoid hospitalizations. For this study, real-life patient data were used from 351 community pharmacies. Direct costs of renal function screening, antibiotic treatments, and medical care due to antibiotic-related hospitalization were included.

RESULTS

The budget impact analysis showed annual cost-savings of €86 per patient through the availability of renal function values in Dutch community pharmacies. Savings were mostly due to avoided hospitalizations.

CONCLUSION

Obtaining and evaluating renal function in community pharmacies by point of care tests is expected to be cost-saving in the Netherlands.
