Impact of a clinical decision support system on pharmacy clinical interventions, documentation efforts, and costs

Mobile Diagnostic Clinics

This article reviews the revolutionary impact of emerging technologies and artificial intelligence (AI) in reshaping modern healthcare systems, with a particular focus on the implementation of mobile diagnostic clinics. It presents an insightful analysis of the current healthcare challenges, including the shortage of healthcare workers, financial constraints, and the limitations of traditional clinics in continual patient monitoring. The concept of "Mobile Diagnostic Clinics" is introduced as a transformative approach where healthcare delivery is made accessible through the incorporation of advanced technologies. This approach is a response to the impending shortfall of medical professionals and the financial and operational burdens conventional clinics face. The proposed mobile diagnostic clinics utilize digital health tools and AI to provide a wide range of services, from everyday screenings to diagnosis and continual monitoring, facilitating remote and personalized care. The article delves into the potential of nanotechnology in diagnostics, AI's role in enhancing predictive analytics, diagnostic accuracy, and the customization of care. Furthermore, the article discusses the importance of continual, noninvasive monitoring technologies for early disease detection and the role of clinical decision support systems (CDSSs) in personalizing treatment guidance. It also addresses the challenges and ethical concerns of implementing these advanced technologies, including data privacy, integration with existing healthcare infrastructure, and the need for transparent and bias-free AI systems.

Reduced prevalence of drug-related problems in psychiatric inpatients after implementation of a pharmacist-supported computerized physician order entry system - a retrospective cohort study

Introduction

In 2021, a computerized physician order entry (CPOE) system with an integrated clinical decision support system (CDSS) was implemented at a tertiary care center for the treatment of mental health conditions in Lübeck, Germany. To date, no study has been reported on the types and prevalence of drug-related problems (DRPs) before and after CPOE implementation in a psychiatric inpatient setting. The aim of this retrospective before-and-after cohort study was to investigate whether the implementation of a CPOE system with CDSS accompanied by the introduction of regular medication plausibility checks by a pharmacist led to a decrease of DRPs during hospitalization and unsolved DRPs at discharge in psychiatric inpatients.

Methods

Medication charts and electronic patient records of 54 patients before (cohort I) and 65 patients after (cohort II) CPOE implementation were reviewed retrospectively by a clinical pharmacist. All identified DRPs were collected and classified based on 'The PCNE Classification V9.1', the German database DokuPIK, and the 'NCC MERP Taxonomy of Medication Errors'.

Results

325 DRPs were identified in 54 patients with a mean of 6 DRPs per patient and 151.9 DRPs per 1000 patient days in cohort I. In cohort II, 214 DRPs were identified in 65 patients with a mean of 3.3 DRPs per patient and 81.3 DRPs per 1000 patient days. The odds of having a DRP were significantly lower in cohort II (OR=0.545, 95% CI 0.412-0.721, p<0.001). The most frequent DRP in cohort I was an erroneous prescription (n=113, 34.8%), which was significantly reduced in cohort II (n=12, 5.6%, p<0.001). During the retrospective in-depth review, more DRPs were identified than during the daily plausibility analyses. At hospital discharge, patients had significantly less unsolved DRPs in cohort II than in cohort I.

Discussion

The implementation of a CPOE system with an integrated CDSS reduced the overall prevalence of DRPs, especially of prescription errors, and led to a smaller rate of unsolved DRPs in psychiatric inpatients at hospital discharge. Not all DRPs were found by plausibility analyses based on the medication charts. A more interactive and interdisciplinary patient-oriented approach might result in the resolution of more DRPs.

Financial impact of medication reviews by clinical pharmacists to reduce in-hospital adverse drug events: a return-on-investment analysis

BACKGROUND

Adverse drug events contribute to rising health care costs. Clinical pharmacists can reduce their risks by identifying and solving drug-related problems (DRPs) through medication review.

AIM

To develop an economic model to determine whether medication reviews performed by clinical pharmacists could lead to a reduction in health care costs associated with the prevention of potential adverse drug events.

METHOD

Two pharmacists performed medication reviews during ward rounds in an internal medicine setting over one year. Avoided costs were estimated by monetizing five categories of DRPs (improper drug selection, drug interactions, untreated indications, inadequate dosages, and drug use without an indication). An expert panel assessed potential adverse drug events and their probabilities of occurrence for 20 randomly selected DRPs in each category. The costs of adverse drug events were extracted from internal hospital financial data. A partial economic study from a hospital perspective then estimated the annual costs avoided by resolving DRPs identified by 3 part-time clinical pharmacists (0.9 full-time equivalent) from 2019 to 2020. The return on investment (ROI) of medication review was calculated.

RESULTS

The estimated annual avoided costs associated with the potential adverse drug events induced by 676 DRPs detected was € 304,170. The cost of a 0.9 full-time equivalent clinical pharmacist was € 112,408. Extrapolated to 1 full-time equivalent, the annual net savings was € 213,069 or an ROI of 1-1.71. Sensitivity analyses showed that the economic model was robust.

CONCLUSION

This economic model revealed the positive financial impact and favorable return on investment of a medication review intervention performed by clinical pharmacists. These findings should encourage the future deployment of a pharmacist-led adverse drug events prevention program.

Clinical Decision Support Tools in the Electronic Medical Record

The integration of clinical decision support (CDS) tools into electronic medical record (EMR) systems has become common. Although there are many benefits for both patients and providers from successful integration, barriers exist that prevent consistent and effective use of these tools. Such barriers include tool alert fatigue, lack of interoperability between tools and medical record systems, and poor acceptance of tools by care providers. However, successful integration of CDS tools into EMR systems have been reported; examples of these include the Statin Choice Decision Aid, and the Kidney Failure Risk Equation (KFRE). This article reviews the history of EMR systems and its integration with CDS tools, the barriers preventing successful integration, and the benefits reported from successful integration. This article also provides suggestions and strategies for improving successful integration, making these tools easier to use and more effective for care providers.

Impact of Clinical Pharmacy Surveillance on Pharmacy Services: A Quality Improvement Project

GOAL

The purpose of this quality improvement project was to retrospectively evaluate pharmacist time to clinical surveillance alert intervention before and after implementing a pharmacy-directed alert priority category across a large for-profit United States health system with well-established clinical pharmacy surveillance software integrated into the clinical pharmacy workflow. The findings contributed to a financial evaluation of pharmacist productivity compared with drug spend for pharmacy-directed interventions that included intravenous (IV)-to-oral-conversion and renal dosing opportunities.

METHODS

A retrospective quality improvement pre-/postanalysis of deidentified, prepopulated clinical surveillance alert data for the preimplementation period of January 1, 2021, through September 30, 2021, was compared with that for the postimplementation period of November 1, 2021, to January 31, 2022, for 169 hospitals. Clinical pharmacist workflow was mapped pre- and postimplementation. The average time to alert intervention was calculated using the mean time in minutes between the alert firing within the software and when the pharmacist reviewed the alert, grouped by hospital, alert status, and priority category. Medications converted from IV to oral were assessed using the clinical surveillance software IV-to-oral calculator. Postimplementation renal dose cost savings were modeled using pharmacist-completed alerts by rule name that indicated a possible dose decrease based on the patient's renal function and current medication.

PRINCIPAL FINDINGS

Time to alert intervention for all completed pharmacist interventions was reduced for high-priority alerts by 32.6 min (p < .001) and routine-priority alerts by 65.1 min (p = .147). Alerts that moved to the pharmacy-directed alert priority category resulted in a reduced time to alert intervention of 38.7 min (p = .003). Normalized average wholesale price (AWP) cost savings from IV-to-oral conversion within 3 days of conversion eligibility were $1,693,600 in the preimplementation period and $1,867,400 in the postimplementation period, a $173,700 increase in cost savings. A total of 7,972 completed postimplementation renal dose adjustments resulted in a modeled AWP normalized cost savings of $1,076,700.

PRACTICAL APPLICATIONS

Results indicated that optimizing clinical surveillance software alerts was effective and increased pharmacist productivity. Specifically, creating a pharmacy-directed alert category that pharmacists were able to complete by hospital policy or protocol improved workflow efficiency and increased IV-to-oral medication conversion cost savings. Further study is needed to validate the renal dose-modeled cost savings and address the financial benefits of quality measures to prevent acute kidney injury.

Best Practice Alerts Informed by Inpatient Opioid Intake to Reduce Opioid Prescribing after Surgery (PRIOR): A Cluster Randomized Multiple Crossover Trial

BACKGROUND

Overprescription of opioids after surgery remains common. Residual and unnecessarily prescribed opioids can provide a reservoir for nonmedical use. This study therefore tested the hypothesis that a decision-support tool embedded in electronic health records guides clinicians to prescribe fewer opioids at discharge after inpatient surgery.

METHODS

This study included 21,689 surgical inpatient discharges in a cluster randomized multiple crossover trial from July 2020 to June 2021 in four Colorado hospitals. Hospital-level clusters were randomized to alternating 8-week periods during which an electronic decision-support tool recommended tailored discharge opioid prescriptions based on previous inpatient opioid intake. During active alert periods, the alert was displayed to clinicians when the proposed opioid prescription exceeded recommended amounts. No alerts were displayed during inactive periods. Carryover effects were mitigated by including 4-week washout periods. The primary outcome was oral morphine milligram equivalents prescribed at discharge. Secondary outcomes included combination opioid and nonopioid prescriptions and additional opioid prescriptions until day 28 after discharge. A vigorous state-wide opioid education and awareness campaign was in place during the trial.

RESULTS

The total postdischarge opioid prescription was a median [quartile 1, quartile 3] of 75 [0, 225] oral morphine milligram equivalents among 11,003 patients discharged when the alerts were active and 100 [0, 225] morphine milligram equivalents in 10,686 patients when the alerts were inactive, with an estimated ratio of geometric means of 0.95 (95% CI, 0.80 to 1.13; P = 0.586). The alert was displayed in 28% (3,074 of 11,003) of the discharges during the active alert period. There was no relationship between the alert and prescribed opioid and nonopioid combination medications or additional opioid prescriptions written after discharge.

CONCLUSIONS

A decision-support tool incorporated into electronic medical records did not reduce discharge opioid prescribing for postoperative patients in the context of vigorous opioid education and awareness efforts. Opioid prescribing alerts might yet be valuable in other contexts.(Anesthesiology 2023; 139:186-96).

EDITOR’S PERSPECTIVE

Evaluating the costs and consequences of computerized clinical decision support systems in hospitals: a scoping review and recommendations for future practice

OBJECTIVE

Sustainable investment in computerized decision support systems (CDSS) requires robust evaluation of their economic impacts compared with current clinical workflows. We reviewed current approaches used to evaluate the costs and consequences of CDSS in hospital settings and presented recommendations to improve the generalizability of future evaluations.

MATERIALS AND METHODS

A scoping review of peer-reviewed research articles published since 2010. Searches were completed in the PubMed, Ovid Medline, Embase, and Scopus databases (last searched February 14, 2023). All studies reported the costs and consequences of a CDSS-based intervention compared with current hospital workflows. Findings were summarized using narrative synthesis. Individual studies were further appraised against the Consolidated Health Economic Evaluation and Reporting (CHEERS) 2022 checklist.

RESULTS

Twenty-nine studies published since 2010 were included. Studies evaluated CDSS for adverse event surveillance (5 studies), antimicrobial stewardship (4 studies), blood product management (8 studies), laboratory testing (7 studies), and medication safety (5 studies). All studies evaluated costs from a hospital perspective but varied based on the valuation of resources affected by CDSS implementation, and the measurement of consequences. We recommend future studies follow guidance from the CHEERS checklist; use study designs that adjust for confounders; consider both the costs of CDSS implementation and adherence; evaluate consequences that are directly or indirectly affected by CDSS-initiated behavior change; examine the impacts of uncertainty and differences in outcomes across patient subgroups.

DISCUSSION AND CONCLUSION

Improving consistency in the conduct and reporting of evaluations will enable detailed comparisons between promising initiatives, and their subsequent uptake by decision-makers.

Detection of Drug-Related Problems through a Clinical Decision Support System Used by a Clinical Pharmacy Team

Clinical decision support systems (CDSSs) are intended to detect drug-related problems in real time and might be of value in healthcare institutions with a clinical pharmacy team. The objective was to report the detection of drug-related problems through a CDSS used by an existing clinical pharmacy team over 22 months. It was a retrospective single-center study. A CDSS was integrated in the clinical pharmacy team in July 2019. The investigating clinical pharmacists evaluated the pharmaceutical relevance and physician acceptance rates for critical alerts (i.e., alerts for drug-related problems arising during on-call periods) and noncritical alerts (i.e., prevention alerts arising during the pharmacist’s normal work day) from the CDSS. Of the 3612 alerts triggered, 1554 (43.0%) were critical, and 594 of these 1554 (38.2%) prompted a pharmacist intervention. Of the 2058 (57.0%) noncritical alerts, 475 of these 2058 (23.1%) prompted a pharmacist intervention. About two-thirds of the total pharmacist interventions (PI) were accepted by physicians; the proportion was 71.2% for critical alerts (i.e., 19 critical alerts per month vs. 12.5 noncritical alerts per month). Some alerts were pharmaceutically irrelevant—mainly due to poor performance by the CDSS. Our results suggest that a CDSS is a useful decision-support tool for a hospital pharmacist’s clinical practice. It can help to prioritize drug-related problems by distinguishing critical and noncritical alerts. However, building an appropriate organizational structure around the CDSS is important for correct operation.

Clinical Decision Support Systems for Antibiotic Prescribing: An Inventory of Current French Language Tools

Clinical decision support systems (CDSSs) are increasingly being used by clinicians to support antibiotic decision making in infection management. However, coexisting CDSSs often target different types of physicians, infectious situations, and patient profiles. The objective of this study was to perform an up-to-date inventory of French language CDSSs currently used in community and hospital settings for antimicrobial prescribing and to describe their main characteristics. A literature search, a search among smartphone application stores, and an open discussion with antimicrobial stewardship (AMS) experts were conducted in order to identify available French language CDSSs. Any clinical decision support tool that provides a personalized recommendation based on a clinical situation and/or a patient was included. Eleven CDSSs were identified through the search strategy. Of the 11 CDSSs, only 2 had been the subject of published studies, while 9 CDSSs were identified through smartphone application stores and expert knowledge. The majority of CDSSs were available free of charge (n = 8/11, 73%). Most CDSSs were accessible via smartphone applications (n = 9/11, 82%) and online websites (n = 8/11, 73%). Recommendations for antibiotic prescribing in urinary tract infections, upper and lower respiratory tract infections, and digestive tract infections were provided by over 90% of the CDSSs. More than 90% of the CDSSs displayed recommendations for antibiotic selection, prioritization, dosage, duration, route of administration, and alternative antibiotics in case of allergy. Information about antibiotic side effects, prescription recommendations for specific patient profiles and adaptation to local epidemiology were often missing or incomplete. There is a significant but heterogeneous offer for antibiotic prescribing decision support in French language. Standardized evaluation of these systems is needed to assess their impact on antimicrobial prescribing and antimicrobial resistance.

Impact of an educational training program on pharmacists' documentation practice at a teaching hospital

Objectives

This study aims to determine the impact of an educational training program on the quantity and quality of the pharmacists’ documentation practice at the Winchester District Memorial Hospital.

Methods

This study is a part of an evaluation for continuous quality improvement, performed applying a pre- and post-test model. The primary endpoint was the number of Pharmacists' Patient-Care Records in patient charts with the listed action codes. Charts of 80 patients were surveyed at three points (two months before and one and three months after the sessions) for 240 charts. Additionally, a pre- and post-educational questionnaire was administered using case scenarios and the Pharmacists’ Patient-Care Record code system.

Results

The number of charts containing Pharmacists’ Patient-Care Records with Action Codes listed is 70%, 73%, and 64% in the first, second, and third chart review rounds, respectively. According to the pre- and post-educational session questionnaire, the average score per pharmacist is 47% and 73%, respectively.

Conclusion

The initial estimate of the documentation practice is 50% or less, which is an underestimation. Furthermore, the quantity of pharmacists’ documentation is not significantly affected by the educational sessions; however, the quality is improved.

Clinical Decision Support Systems in Otolaryngology-Head and Neck Surgery: A State of the Art Review

OBJECTIVE

To offer practical, evidence-informed knowledge on clinical decision support systems (CDSSs) and their utility in improving care and reducing costs in otolaryngology-head and neck surgery. This primer on CDSSs introduces clinicians to both the capabilities and the limitations of this technology, reviews the literature on current state, and seeks to spur further progress in this area.

DATA SOURCES

PubMed/MEDLINE, Embase, and Web of Science.

REVIEW METHODS

Scoping review of CDSS literature applicable to otolaryngology clinical practice. Investigators identified articles that incorporated knowledge-based computerized CDSSs to aid clinicians in decision making and workflow. Data extraction included level of evidence, Osheroff classification of CDSS intervention type, otolaryngology subspecialty or domain, and impact on provider performance or patient outcomes.

CONCLUSIONS

Of 3191 studies retrieved, 11 articles met formal inclusion criteria. CDSS interventions included guideline or protocols support (n = 8), forms and templates (n = 5), data presentation aids (n = 2), and reactive alerts, reference information, or order sets (all n = 1); 4 studies had multiple interventions. CDSS studies demonstrated effectiveness across diverse domains, including antibiotic stewardship, cancer survivorship, guideline adherence, data capture, cost reduction, and workflow. Implementing CDSSs often involved collaboration with health information technologists.

IMPLICATIONS FOR PRACTICE

While the published literature on CDSSs in otolaryngology is finite, CDSS interventions are proliferating in clinical practice, with roles in preventing medical errors, streamlining workflows, and improving adherence to best practices for head and neck disorders. Clinicians may collaborate with information technologists and health systems scientists to develop, implement, and investigate the impact of CDSSs in otolaryngology.

An overview of clinical decision support systems: benefits, risks, and strategies for success

Computerized clinical decision support systems, or CDSS, represent a paradigm shift in healthcare today. CDSS are used to augment clinicians in their complex decision-making processes. Since their first use in the 1980s, CDSS have seen a rapid evolution. They are now commonly administered through electronic medical records and other computerized clinical workflows, which has been facilitated by increasing global adoption of electronic medical records with advanced capabilities. Despite these advances, there remain unknowns regarding the effect CDSS have on the providers who use them, patient outcomes, and costs. There have been numerous published examples in the past decade(s) of CDSS success stories, but notable setbacks have also shown us that CDSS are not without risks. In this paper, we provide a state-of-the-art overview on the use of clinical decision support systems in medicine, including the different types, current use cases with proven efficacy, common pitfalls, and potential harms. We conclude with evidence-based recommendations for minimizing risk in CDSS design, implementation, evaluation, and maintenance.

Antimicrobial stewardship staffing: How much is enough?

Antimicrobial stewardship improves patient care and reduces antimicrobial resistance, inappropriate use, and adverse outcomes. Despite high-profile mandates for antimicrobial stewardship programs across the healthcare continuum, descriptive data, and recommendations for dedicated resources, including appropriate physician, pharmacist, data analytics, and administrative staffing support, are not robust. This review summarizes the current literature on antimicrobial stewardship staffing and calls for the development of minimum staffing recommendations.

Impact of pharmacists' interventions on physicians' decision of a knowledge-based renal dosage adjustment system

Background Early interventions with clinical decision support system (CDSS) guidance have ensured appropriate drug dosing for patients with renal impairment. However, the low rates of physician compliance with CDSS alerts have been reported. Objective We investigated whether designated pharmacist interventions were associated with physician' acceptance of the knowledge-based renal dosage adjustment system (K-RDS) for patients with reduced renal function. Setting A retrospective, single-center study was conducted using a healthcare information system at a tertiary teaching hospital. Methods This study compared physicians' acceptance of the K-RDS with and without designated pharmacists. The severity of prescription errors and the impact of service provided by the pharmacist were evaluated using the validated method developed by Overhage and Lukes. From April to June 2017, we enrolled patients who were ≥ 20 years of age and admitted with an estimated glomerular filtration rate under 50 ml/min on medications that required dose adjustments. Main outcomes measure The number of dosing alerts of the K-RDS and physicians' acceptance rates were compared between a control group guided by the central pharmacy only and a group with assigned designated pharmacists. The factors associated with the physicians' acceptance rate were also analyzed using a multivariate logistic regression method. The impact of service provided by the pharmacist were considered as 'highly significant' (categories: 1-2). Severity of prescription errors were defined as 'serious' if they corresponded to categories 1-2 of the Overhage and Lukes scale for severity, and interventions were relevant if they corresponded to categories 1-3 in the impact of  service provided by the pharmacist scale. Results Among 1363 prescription interventions, 491 (36.0%) were performed by designated pharmacists. The K-RDS alert acceptance rate by the physicians was 54.4% in the designated pharmacist group and 47.0% in the control group (p = 0.0233). The statistically significant association was found in the designated pharmacists group in 'highly significant' service provided by the pharmacist (p < 0.001, OR 1.772; 95% CI 1.362-2.305) and 'serious' severity of prescription errors (p = 0.012, OR 1.657; 95% CI 1.116-2.460). The presence of designated pharmacists (OR 1.353, p = 0.0272), patient's gender (OR 0.758, p = 0.0016), department specialty (OR 0.659, p < 0.0001), eGFR (OR 1.538 if < 10 ml/min; OR 1.519 if 10-40 ml/min, p < 0.0001), and medications (OR 6.058-43.992 depending on the medication category, p < 0.0001) were significant factors affecting physicians' acceptance. Conclusion Pharmacists' interventions effectively improved physicians' acceptance of the K-RDS alerts.

Value of hospital antimicrobial stewardship programs [ASPs]: a systematic review

Background

Hospital antimicrobial stewardship programs (ASPs) aim to promote judicious use of antimicrobials to combat antimicrobial resistance. For ASPs to be developed, adopted, and implemented, an economic value assessment is essential. Few studies demonstrate the cost-effectiveness of ASPs. This systematic review aimed to evaluate the economic and clinical impact of ASPs.

Methods

An update to the Dik et al. systematic review (2000–2014) was conducted on EMBASE and Medline using PRISMA guidelines. The updated search was limited to primary research studies in English (30 September 2014–31 December 2017) that evaluated patient and/or economic outcomes after implementation of hospital ASPs including length of stay (LOS), antimicrobial use, and total (including operational and implementation) costs.

Results

One hundred forty-six studies meeting inclusion criteria were included. The majority of these studies were conducted within the last 5 years in North America (49%), Europe (25%), and Asia (14%), with few studies conducted in Africa (3%), South America (3%), and Australia (3%). Most studies were conducted in hospitals with 500–1000 beds and evaluated LOS and change in antibiotic expenditure, the majority of which showed a decrease in LOS (85%) and antibiotic expenditure (92%). The mean cost-savings varied by hospital size and region after implementation of ASPs. Average cost savings in US studies were $732 per patient (range: $2.50 to $2640), with similar trends exhibited in European studies. The key driver of cost savings was from reduction in LOS. Savings were higher among hospitals with comprehensive ASPs which included therapy review and antibiotic restrictions.

Conclusions

Our data indicates that hospital ASPs have significant value with beneficial clinical and economic impacts. More robust published data is required in terms of implementation, LOS, and overall costs so that decision-makers can make a stronger case for investing in ASPs, considering competing priorities. Such data on ASPs in lower- and middle-income countries is limited and requires urgent attention.

Role of Technology in Antimicrobial Stewardship

Because of the increasing plague of antimicrobial resistance and antibiotic misuse, antimicrobial stewardship programs (ASPs) are now a mandatory entity in all US hospitals. ASPs can use technological advances, such as the electronic medical record and clinical decision support systems, to impact a larger patient population with more efficiency. Additionally, through the use of mobile applications and social media, ASPs can highlight and propagate educational information regarding antimicrobial utilization to patients and providers in a widespread and timely manner. In this article, the authors describe how technology can play an important role in antimicrobial stewardship.

Antimicrobial Stewardship in Community Hospitals

Antibiotic stewardship programs are needed in all health care facilities, regardless of size and location. Community hospitals that have fewer resources may have different priorities and require different strategies when defining antibiotic stewardship program components and implementing interventions. By following the Centers for Disease Control and Prevention Core Elements and using the strategies suggested in this article, readers should be able to design, develop, participate in, or improve antibiotic stewardship programs within community hospitals.

Clinical Pharmacist Impact on Intensive Care Unit Delirium: Intervention and Monitoring

Purpose: The purpose of this study was to determine the impact of pharmacist monitoring with a clinical decision support system (CDSS) on clinical outcomes related to intensive care unit (ICU) delirium. Methods: This was a single-center, before-and-after study. This study compares patient outcomes of the preintervention group, which is the standard of care of pharmacist rounding, and the intervention group of pharmacy rounding with the CDSS rules. Using a CDSS, specific delirium risk factor rules were created to alert pharmacists to patients who have an increased risk of developing ICU delirium. Patients were included in the study if they were ⩾18 years of age, admitted to the trauma intensive care unit (TICU), and had one of the CDSS rule alerts. The CDSS notified pharmacists in real time to patients in the intervention group that met these criteria to provide timely recommendations in an effort to prevent ICU delirium. Results: Compared with the preintervention group receiving the standard of care (n = 28), the intervention CDSS group (n = 33) had a nonsignificant trend in decreased incidence of delirium (33.3% vs 24.1%, P = .45), ICU length of stay (LOS) (10.11 vs 7.55 days, P = .26), and ventilator duration (7.11 vs 5.03 days, P = .26). The intervention group had a significantly shorter hospital LOS (14.74 vs 9.98 days, P = .04). There was a nonsignificant increase in mortality with the intervention group from nondelirium causes (24.2% vs 7%, P = .07). Conclusion: The utilization of a CDSS by clinical pharmacists to monitor for delirium-specific risk factors led to a significantly shorter hospital LOS. Further studies using this model are warranted to see the impact on the ICU population.

The effectiveness of computerised decision support on antibiotic use in hospitals: A systematic review

Background

Inappropriate antimicrobial use has been shown to be an important determinant of the emergence of antimicrobial resistance (AMR). Health information technology (HIT) in the form of Computerised Decision Support (CDS) represents an option for improving antimicrobial prescribing and containing AMR.

Objectives

To evaluate the evidence for CDS in improving quantitative and qualitative measures of antibiotic prescribing in inpatient hospital settings.

Methods

A systematic literature search was conducted of articles published from inception to 20^th December 2014 using eight electronic databases: MEDLINE, EMBASE, PUBMED, Web of Science, CINAHL, Cochrane Library, HMIC and PsychINFo. An updated systematic literature search was conducted from January 1^st 2015 to October 1^st 2016 using PUBMED. The search strategy used combinations of the following terms: (electronic prescribing) OR (clinical decision support) AND (antibiotic or antibacterial or antimicrobial) AND (hospital or secondary care or inpatient). Studies were evaluated for quality using a 10-point rating scale.

Results

Eighty-one studies were identified matching the inclusion criteria. Seven outcome measures were evaluated: adequacy of antibiotic coverage, mortality, volume of antibiotic usage, length of stay, antibiotic cost, compliance with guidelines, antimicrobial resistance, and CDS implementation and uptake. Meta-analysis of pooled outcomes showed CDS significantly improved the adequacy of antibiotic coverage (n = 13; odds ratio [OR], 2.11 [95% CI, 1.67 to 2.66, p ≤ 0.00001]). Also, CDS was associated with marginally lowered mortality (n = 20; OR, 0.85 [CI, 0.75 to 0.96, p = 0.01]). CDS was associated with lower antibiotic utilisation, increased compliance with antibiotic guidelines and reductions in antimicrobial resistance. Conflicting effects of CDS on length of stay, antibiotic costs and system uptake were also noted.

Conclusions

CDS has the potential to improve the adequacy of antibiotic coverage and marginally decrease mortality in hospital-related settings.

Evaluation of effects of an operational multidisciplinary team on antibiotic use in the medium to long term at a French university hospital

Background Antibiotic-resistant bacteria are a major public health problem throughout the world. In 2006, in accordance with the national guidelines for antibiotic use, the CHRU of Nancy created an operational multidisciplinary antibiotic team at one of its sites. In 2011, a cluster-controlled trial showed that the operational multidisciplinary antibiotic team (the intervention) had a favourable short-term effect on antibiotic use and costs. Objective Our objective was to determine whether these effects continued over the medium to long term (that is, 2-7 years after creation of the operational multidisciplinary antibiotic team, 2009-2014). Setting The 1800-bed University Hospital of Nancy (France). Method The effect in the medium to long term is measured according to the same criteria and assessed by the same methods as the first study. A cluster controlled trial was performed on the period 2009-2014. The intervention group comprised 11 medical and surgical wards in settings where the operational multidisciplinary antibiotic team was implemented and the control group comprised 6 wards without this operational team. Main outcome measure Consumption of antibiotics overall and by therapeutic class (in defined daily doses per 1000 patient-days) and costs savings (in €). Results The reduction in antibiotic use and costs continued, but at a lower rate than in the short term (11% between 2009 and 2014 compared with 33% between 2007 and 2009) at the site of the intervention. The principal decreases concerned fluoroquinolones and glycopeptides. At the site without an operational multidisciplinary antibiotic team (the control group), total antibiotic use remained stable. Between 2009 and 2014, costs fell 10.5% in the intervention group and 5.7% in the control group. Conclusion This study shows that it is possible to maintain the effectiveness over time of such an intervention and demonstrates its role in defining a hospital's antibiotic policy.

Pharmacist recommendations in an intensive care unit: three-year clinical activities

Objective

To analyze the clinical activities performed and the accepted pharmacist recommendations made by a pharmacist as a part of his/her daily routine in an adult clinical intensive care unit over a period of three years.

Methods

A cross-sectional, descriptive, and exploratory study was conducted at a tertiary university hospital from June 2010 to May 2013, in which pharmacist recommendations were categorized and analyzed.

Results

A total of 834 pharmacist recommendations (278 per year, on average) were analyzed and distributed across 21 categories. The recommendations were mainly made to physicians (n = 699; 83.8%) and concerned management of dilutions (n = 120; 14.4%), dose adjustment (n = 100; 12.0%), and adverse drug reactions (n = 91; 10.9%). A comparison per period demonstrated an increase in pharmacist recommendations with larger clinical content and a reduction of recommendations related to logistic aspects, such as drug supply, over time. The recommendations concerned 948 medications, particularly including systemic anti-infectious agents.

Conclusion

The role that the pharmacist played in the intensive care unit of the institution where the study was performed evolved, shifting from reactive actions related to logistic aspects to effective clinical participation with the multi-professional staff (proactive actions).

Structured Pharmacist Review of Medication in Older Hospitalised Patients: A Cost-Effectiveness Analysis

BACKGROUND

A recent cluster randomised controlled trial (RCT) conducted in an Irish hospital evaluating a structured pharmacist review of medication (SPRM), supported by computerised clinical decision support software (CDSS), demonstrated positive outcomes in terms of reduction of adverse drug reactions (ADR).

OBJECTIVE

The aim of this study was to examine the cost effectiveness of pharmacists applying an SPRM in conjunction with CDSS to older hospitalised patients compared with usual pharmaceutical care.

METHOD

Cost-effectiveness analysis alongside a cluster RCT. The trial was conducted in a tertiary hospital in the south of Ireland. Patients in the intervention arm (n = 361) received a multifactorial intervention consisting of medicines reconciliation, deployment of CDSS and generation of a pharmaceutical care plan. Patients in the control arm (n = 376) received usual care from the hospital pharmacy team. Incremental cost effectiveness was examined in terms of costs to the healthcare system and an outcome measure of ADRs during an inpatient hospital stay. Uncertainty in the analysis was explored using a cost-effectiveness acceptability curve (CEAC).

RESULTS

On average, the intervention arm was the dominant strategy in terms of cost effectiveness. Compared with usual care (control), the intervention was associated with a decrease of €807 [95% confidence interval (CI) -3443 to 1829; p = 0.548) in mean healthcare cost, and a decrease in the mean number of ADR events per patient of -0.064 (95% CI -0.135 to 0.008; p = 0.081). The probability of the intervention being cost effective at respective threshold values of €0, €250, €500, €750, €1000 and €5000 was 0.707, 0.713, 0.716, 0.718, 0.722 and 0.784, respectively.

CONCLUSIONS

Based on the evidence presented, SPRM/CDSS is likely to be determined to be cost effective compared with usual pharmaceutical care. However, neither incremental costs nor effects demonstrated a statistically significant difference, therefore the results of this single-site study should be interpreted with caution.

Impact of pharmacist interventions on cost avoidance in an ambulatory cancer center

Objective

To provide a foundation to justify the presence of a full-time clinical pharmacist in the ambulatory cancer center in addition to an existing centralized pharmacist through cost avoidance calculation and patient and staff satisfaction surveys.

Methods

The prospective, pilot study took place in an ambulatory cancer center over four weeks in 2014. Cost avoidance values were assigned to interventions performed by a pharmacy resident, who was present in the ambulatory cancer center during clinic hours, along with a centralized oncology pharmacist routinely working with the cancer center. Anonymous patient and staff satisfaction surveys based on a 5-point Likert scale were distributed to assess the perceived benefit of a pharmacist located in the ambulatory cancer center.

Results

Data collection took place over approximately one month. After evaluation of 962 interventions from both pharmacists, the estimated cost avoidance was US$282,741 per pharmacist per year, yielding a net benefit of US$138,441. The most common interventions made by the resident included chemotherapy regimen review (n = 290, 69%) and patient counseling (n = 102, 24%), while the majority of the centralized pharmacist’s interventions was chemotherapy regimen review (n = 525, 97%). Results from the anonymous patient and staff surveys revealed an overall positive perception of the pharmacy resident while in the ambulatory cancer center.

Conclusion

A full-time clinical pharmacist in an ambulatory cancer center is both financially beneficial and positively perceived by patients and staff.

Can we document the practice of dispensing? A systematic review

WHAT IS KNOWN

Documentation is a process indicator utilized to evaluate quality clinical pharmacist services. In this framework, documentation of dispensing, besides supporting patient care, allows evaluation of the impact of counselling.

OBJECTIVE

To identify and assess studies of documentation by pharmacists in the dispensing process.

METHOD

A systematic review was carried out according to the following steps: (i) identification of studies in the following databases: PubMed/Medline, Web of Science, Scopus and Lilacs, using the descriptors 'counselling', 'dispensing', 'community pharmacy services', 'pharmacies' and 'pharmacists' in different combinations; (ii) evaluation of studies, in which the title, abstract and full text of the studies, and the evaluation of the methodological quality of the selected studies were analysed.

RESULTS

In total, 26 articles met the specific criteria. Few studies addressed documentation as part of the dispensing working process (3), and 16 articles reported documentation using non-electronic systems. The main variables documented were patient information, drug therapy problems and clinical interventions. Furthermore, 20 studies showed the effects of documentation in the dispensing process and 23 studies included statistical evidence. Eight articles met between 42% and 75% of the 28 items recommended by the STROBE initiative, and two articles met approximately 60% of the 36 items recommended by the CONSORT initiative.

WHAT IS NEW AND CONCLUSION

Few studies address documentation as part of the dispensing working process. Thus, researchers should be concerned with standardizing documentation and implementing more robust designs and multicenter studies.

Improvements in a program to convert i.v. to oral medications at an academic medical center

PURPOSE

Results of a study to implement targeted interventions to increase the number of documented i.v.-to-oral conversions and to increase cost savings from these documented conversions are reported.

METHODS

A before-and-after analysis of i.v.-to-oral conversions at an academic medical center following the addition of targeted interventions to an existing pharmacist-initiated conversion program was conducted. Targeted interventions included staff training on i.v.-to-oral conversions, implementation of a new documentation system, and feedback to the staff. Major outcomes studied included the total number of i.v.-to-oral conversions documented per month and the cost savings generated by these conversions.

RESULTS

The mean ± S.D. number of i.v.-to-oral conversions documented per month significantly increased after the implementation of targeted interventions (25 ± 9 before and 57 ± 6 after implementation, p < 0.0001). There was a nonsignificant increase in cost savings generated per month after implementation of the interventions. The most commonly converted medication was pantoprazole. Conversions of levetiracetam generated the highest cost savings.

CONCLUSION

Addition of several targeted interventions to an existing pharmacist-initiated i.v.-to-oral conversion program led to a significant increase in the total number of documented conversions.

Clinical pharmacy service practice in a Chinese tertiary hospital

Clinical pharmacy service is focused on the rationality and safety of medication therapy. Clinical pharmacists play an important role in designing therapeutic regimen, preventing medication errors, reducing the incidence of adverse drug reaction, and saving medical costs. Although clinical pharmacy service in China is in its early stage, its development is rapid. In this manuscript, the working model of clinical pharmacists in a Chinese tertiary hospital is introduced, including ward rounds, consultation, stewardship of antimicrobial therapy, drug adverse reaction monitoring, therapeutic drug monitoring, clinical pharmacokinetics and pharmacogenetics, and training system. With the efforts of clinical pharmacists, there will be a significant increase in the optimization of medication therapy and a notable reduction in preventable adverse drug events as well as health-care cost in China.

Comparison of Time to Therapeutic aPTT in Patients Who Received Continuous Unfractionated Heparin After Implementation of Pharmacy-wide Intervention Alerts

Background: For patients on continuous IV unfractionated heparin (UFH), failing to achieve a therapeutic aPTT by 24 hours can be associated with increased morbidity. A pharmacy clinical surveillance system (PCSS) subtherapeutic aPTT alert was implemented at our institution to improve achievement of therapeutic aPTT goals by 24 hours. Objective: The primary objective was the time to achieve the minimum goal aPTT before and after the alert implementation. The secondary objectives were to examine the percentage of patients who achieved the minimum goal aPTT by 24 hours and the number of dose changes to achieve the minimum goal aPTT. Methods: A single-center retrospective study was conducted to include all adult inpatients receiving a continuous UFH infusion during a 3-month period prior to the implementation of a subtherapeutic aPTT alert and a 3-month period after implementation. Results: 317 patients were included in the analysis. The average time to achieve the minimum goal aPTT was 21.8 hours prior to alert implementation and 15.4 hours after implementation (p = .002). The percent of patients who achieved the minimum goal aPTT by 24 hours was 65.7% prior to alert implementation and 82.4% after implementation (p = .035). The average number of dose changes necessary to achieve aPTT value to the minimum goal aPTT prior to alert implementation was 1.67 and 1. 98 after implementation (p = .68). Conclusion: This analysis showed that implementation of a PCSS subtherapeutic aPTT alert for patients on continuous UFH infusions may ensure patients reach goal aPTT faster and facilitate a higher percent of patients who achieve the minimum goal aPTT by 24 hours.

The pharmacist and the EHR

The adoption of electronic health records (EHRs) across the United States has impacted the methods by which health care professionals care for their patients. It is not always recognized, however, that pharmacists also actively use advanced functionality within the EHR. As critical members of the health care team, pharmacists utilize many different features of the EHR. The literature focuses on 3 main roles: documentation, medication reconciliation, and patient evaluation and monitoring. As health information technology proliferates, it is imperative that pharmacists' workflow and information needs are met within the EHR to optimize medication therapy quality, team communication, and patient outcomes.

The emergence and evolution of antimicrobial resistance: Impact on a global scale

The evolution of antimicrobial resistance is a multifaceted issue that is influenced by numerous factors. This growing healthcare problem has significantly impacted the public welfare and has substantially burdened the economic system on a global scale. In an effort to combat this rising problem, several strategies have been implemented in the recent years to stall the progression and decrease the emergence of antimicrobial resistance. The aim of this review article is to describe the various factors that have contributed to the current state of antimicrobial resistance and to evaluate potential strategies developed to reduce the burden of antimicrobial resistance.

Utilization of a Pharmacy Clinical Surveillance System for Pharmacist Alerting and Communication at a Tertiary Academic Medical Center

The objective of this analysis is to describe the utilization metrics of a pharmacy clinical surveillance system (PCSS) at a tertiary, academic medical center.We performed a retrospective database analysis assessing rule-based alerts (RBA), interventions and pharmacist communication notes documented in the PCSS from January 1, 2014 to December 31, 2014. Reports were generated on 92 unique RBAs sent to clinicians for evaluation. Metrics assessed included the number of RBAs that were triggered, clinically evaluated, intervened on by pharmacists, and therapeutic category of interventions. Pharmacy communication notes were also evaluated.A total of 399,979 RBAs were triggered through the PCSS. During that time, pharmacists documented a total of 17,733 interventions. The most common RBAs were related to lab abnormalities (132,487; 33 %) and anticoagulation/antiplatelet therapy (126,425; 32.1 %). Interventions were most frequently related to RBAs regarding anticoagulation/antiplatelet therapy (6412; 36 %) and antimicrobial therapy (3320; 19 %). Pharmacist communication was most commonly related to clarification of medication and lab orders, and therapeutic drug monitoring.Based on utilization metrics presented, the implementation of a PCSS has successfully generated RBAs to aid pharmacists in clinical practice and improved departmental documentation and communication. Further analysis is warranted to assess the impact of the RBAs, interventions, and communication notes on outcomes such as hospital cost and adverse drug events.

Use of electronic health records and clinical decision support systems for antimicrobial stewardship

Electronic health records (EHRs) and clinical decision support systems (CDSSs) have the potential to enhance antimicrobial stewardship. Numerous EHRs and CDSSs are available and have the potential to enable all clinicians and antimicrobial stewardship programs (ASPs) to more efficiently review pharmacy, microbiology, and clinical data. Literature evaluating the impact of EHRs and CDSSs on patient outcomes is lacking, although EHRs with integrated CDSSs have demonstrated improvements in clinical and economic outcomes. Both technologies can be used to enhance existing ASPs and their implementation of core ASP strategies. Resolution of administrative, legal, and technical issues will enhance the acceptance and impact of these systems. EHR systems will increase in value when manufacturers include integrated ASP tools and CDSSs that do not require extensive commitment of information technology resources. Further research is needed to determine the true impact of current systems on ASP and the ultimate goal of improved patient outcomes through optimized antimicrobial use.

Transformation of antimicrobial stewardship programs through technology and informatics

The successful integration of technology in antimicrobial stewardship programs has made it possible for clinicians to function more efficiently. With government endorsement of electronic health records (EHRs), EHRs and clinical decision support systems (CDSSs) are being used as decision support tools to aid clinicians in efforts to improve antibiotic use. Likewise, medical applications (apps) have provided educational tools easily accessible to clinicians through their mobile devices. In this article, the impact that informatics and technology have had on promoting antibiotic stewardship is described, focusing on EHRs and CDSSs, apps, electronic resources, and social media.
