Pharmacists as Care Providers for Stroke Patients: A Systematic Review.

BACKGROUND: Pharmacists have become an integral member of the multidisciplinary team providing clinical patient care in various healthcare settings. Although evidence supporting their role in the care of patients with other disease states is well-established, minimal literature has been published evaluating pharmacist interventions in stroke patients. The purpose of this systematic review is to summarize the evidence evaluating the impact of pharmacist interventions on stroke patient outcomes. METHODS: Study abstracts and full-text articles evaluating the impact of a pharmacist intervention on outcomes in patients with an acute stroke/transient ischemic attack (TIA) or a history of an acute stroke/TIA were identified and a qualitative analysis performed. RESULTS: A total of 20 abstracts and full-text studies were included. The included studies provided evidence supporting pharmacist interventions in multiple settings, including emergency departments, inpatient, outpatient, and community pharmacy settings. In a significant proportion of the studies, pharmacist care was collaborative with other healthcare professionals. Some of the pharmacist interventions included participation in a stroke response team, assessment for thrombolytic use, medication reconciliation, participation in patient rounds, identification and resolution of drug therapy problems, risk-factor reduction, and patient education. Pharmacist involvement was associated with increased use of evidence-based therapies, medication adherence, risk-factor target achievement, and maintenance of health-related quality of life. CONCLUSIONS: Available evidence suggests that a variety of pharmacist interventions can have a positive impact on stroke patient outcomes. Pharmacists should be considered an integral member of the stroke patient care team.

Assessing the Physicochemical Stability of a Compounded Neonatal Trace Element Solution.

PURPOSE: Alberta Health Services (AHS) recommends the adoption of a new neonatal multi-trace element formulation containing zinc sulfate, copper sulfate, selenious acid and sodium iodide to be compounded internally in appropriate AHS pharmacies. The objective of this study was to assess the physicochemical stability of this formulation under commonly used storage conditions. METHOD: Three batches of trace element solution were compounded by University of Alberta Hospital pharmacy staff using sterile compounding procedures. Appropriate amount of zinc sulfate (500 mg/mL), copper sulfate (40 mg/mL), selenious acid (4 mg/mL), sodium iodide (2 mg/mL) and sterile water for injection were mixed. Samples from each batch were divided in individual vials and syringes for each time point and kept protected from light either at room temperature (15-30°C) or fridge (2-8°C). Vial samples were also kept at room temperature for 12 h and then transferred to fridge. Vial samples were analyzed at time 0, 12 h, and 1, 3, 7, 9, 30, 60, 90 days for their physical appearance and pH, then centrifuged and assessed for the soluble zinc (atomic absorption), copper (atomic absorption), selenium (ICP-MS) and iodine (HPLC and ICP-MS) concentrations. Syringe samples were tested at time 0 and 12 h for element concentrations. RESULTS: Under all storage conditions, when stored in vials, samples' appearance, pH and soluble zinc, copper and selenium concentrations stayed within the USP acceptable limits up to 90 days. Iodine concentration was within the permitted limits only up to 7 days. The USP recommended HPLC method of iodine analysis seemed inadequate for this preparation and needed modifications, through frequent washing of the column with KI (2 %) solution. Samples kept in syringes at room temperature, showed lower than permitted concentration of Zn at 12h in this study. CONCLUSION: The AHS neonatal multi-trace element formulation seem to be physio-chemically stable up to 7 days in all three storage conditions when kept in vials.  A decline in iodine concentration is seen after 7 days irrespective of storage conditions. This article is open to POST-PUBLICATION REVIEW.

Secondary stroke prevention: practice patterns in a tertiary care stroke service.

BACKGROUND: Stroke and transient ischemic attack (TIA) have a high personal and financial cost to society and prevention is critical. Outside of registries in Ontario, there has been little effort to determine whether care gaps exist for secondary preventative care within Canada. The objective of this study was to evaluate inpatient medical team compliance to four secondary stroke prevention interventions: antithrombotic therapy, antihypertensive therapy, lipid lowering therapy and smoking cessation. METHODS: Adults admitted to the University of Alberta Hospital stroke service with a diagnosis of stroke or TIA between August 1st, 2005 and July 31st, 2006 were identified using International Classification of Diseases (10th Revision) codes. Two hundred charts were randomly selected for retrospective review. Compliance, defined as achievement of therapeutic targets or appropriate therapy for subtherapeutic targets, was assessed. RESULTS: Among 190 eligible patients (mean age 67 years, 55% male), 147 (77.4%) had a non-cardioembolic cerebral event while 43 (22.6%) had a cardioembolic cerebral event. We found high compliance for antithrombotic (92% [174/190]) and antihypertensive (95% [136/143]) agents, but suboptimal compliance for lipid lowering agents (68% [107/158]) and smoking cessation (27% [17/64]). CONCLUSIONS: There is room for improvement in early risk factor management for secondary prevention, even in specialized stroke centres. To optimize stroke preventative care, more interdisciplinary collaboration, investigation of reasons for suboptimal care, development of strategies to minimize care gaps and ongoing stroke care audits for quality improvement are needed.

Care providers' satisfaction with restructured clinical pharmacy services in a tertiary care teaching hospital.

BACKGROUND: At the time this study was undertaken, clinical pharmacy services at the authors' institution, a tertiary care teaching hospital, were largely reactive in nature, with patients and units receiving inconsistent coverage. OBJECTIVE: To develop an evidence-based model of proactive practice and to evaluate the satisfaction of pharmacists and other stakeholders after restructuring of clinical pharmacy services. METHODS: The literature was reviewed to determine a core set of pharmacist services associated with the greatest beneficial impact on patients' health. On the basis of established staffing levels, the work schedule was modified, and pharmacists were assigned to a limited number of patient care teams to proactively and consistently provide these core services. Other patient care teams continued to receive reactive troubleshooting-based services, as directed by staff in the pharmacy dispensary. A satisfaction survey was distributed to all pharmacists, nurses, and physicians 18 months after the restructuring. RESULTS: Of the 26 pharmacists who responded to the survey, all agreed or strongly agreed that the restructuring of services had improved job satisfaction and patient safety and that other health care professionals valued their contribution to patient care. Nurses and physicians from units where pharmacists had been assigned to provide proactive services perceived pharmacist services more favourably than those from units where pharmacist services were reactive. Pharmacists, nurses, and physicians all felt that proactive pharmacist services should be more widely available. Challenges reported by pharmacists included increased expectations for documentation and guilt about "cutting back" services where they had previously been provided. CONCLUSIONS: Restructuring clinical pharmacy services in an evidence-based manner improved pharmacists' satisfaction and created demand from other stakeholders to provide this level of service for all patients.

Strategies to optimize implementation of novel preceptorship models: Peer-assisted learning and near-peer teaching.

INTRODUCTION: Hospital experiential placements have traditionally used a 1:1 (student to preceptor) ratio. Two models, peer-assisted learning (PAL) and near-peer teaching (NPT), have been described in the literature for education of health professions. This research explored the use of PAL and NPT, as well as advantages, challenges, and strategies to address challenges for implementation. METHODS: This study used an anonymous survey to solicit feedback from staff pharmacists and pharmacy leaders about their use of PAL and NPT models in hospital settings in Alberta, Canada. Using closed and open-ended questions, experience with each model and implementation considerations were explored. RESULTS: The survey was completed by 115 hospital pharmacists (11% response rate). PAL and NPT were utilized by 25% and 8% of respondents, respectively, and 10% had experience with both models. Advantages of these models include promoting teamwork and clinical independence, learners supporting each other, and fostering active learning. The highest ranked challenges were space/technology/computer access limitations and additional time to complete learner assessments. Many strategies were provided to address challenges, and facilitate implementation and utilization. CONCLUSION: In the hospital setting, pharmacists used PAL more commonly than NPT. Feedback from pharmacists and leaders affirmed the advantages and challenges associated with use of these precepting models. Strategies to facilitate and optimize use were provided, which will guide faculty, pharmacy leaders, and preceptors in efforts to support implementation to increase capacity and expand the practice of precepting.

Pharmacist Prescribing in Pediatric and Neonatal Acute Care: An Observational Study.

OBJECTIVE: The intent of this project was to objectively describe the frequency of pharmacist prescribing in acute care pediatrics and neonatology and to determine the medications most often prescribed by pharmacists practicing in a jurisdiction that permits pharmacists' prescribing. METHODS: This was a subgroup analysis of a retrospective observational study using prescribing data from an electronic medical record system used in 5 acute care hospitals (1 pediatric, 4 primarily adult but with pediatric and neonatal units) within Calgary, Alberta, Canada. RESULTS: Considering orders for pediatric or neonatal patients only, there was a mean (SD) of 126 (226) prescriptions per pharmacist per year, with a wide range (1-1101 per year). Considering only the 9 clinical pharmacist full-time equivalents (FTEs) assigned to pediatrics and/or neonatology (i.e., not including dispensary pharmacist FTE), this represents 572 prescriptions per clinical pharmacist FTE per year (726 in pediatrics and 380 in neonatology). The most common medication classes on pediatric units included anti-infective agents, central nervous system agents, and gastrointestinal agents. In NICUs, blood formation, coagulation and thrombosis agents (mainly iron), electrolytes, caloric and water balance agents (primarily sodium supplements), and vitamins were also commonly prescribed by pharmacists. CONCLUSIONS: As the scope of pharmacy practice expands to include prescribing, health team leadership can use these data to support incorporation of this role into practice. Prescribing pharmacists can ensure appropriate use of many medications used in acutely ill infants and children, potentially improving efficiency and quality of care.

CAPABLE: Calgary zone usage of Additional Prescribing Authorization By pharmacists in an inpatient setting: review of the prescribing Landscape and Environment.

BACKGROUND: In Alberta, Canada, pharmacists have been granted the ability to prescribe most medications independently after completing an additional authorization process. While there are data to support the use of pharmacists' prescribing in the community setting, little is known about its use in the inpatient hospital setting. OBJECTIVES: To describe the prescribing patterns of pharmacists in an inpatient setting including the percentage of pharmacists using their prescribing authority, the care areas where prescribing occurred, and the frequency of prescribing. Secondary objectives included describing the medications prescribed, and to determine if pharmacists are documenting their prescribing interventions. METHODS: A descriptive, retrospective, cross-sectional study of medications ordered by pharmacists through the electronic order entry system in Calgary, Alberta, Canada. Prescriptions were examined in the context of how often each pharmacist prescribed, the medications prescribed, and an audit of documentation practices was performed using patient charts. RESULTS: A total of 64,293 orders from 172 pharmacists were included in the analysis, of which 51% (n = 32,681) were discontinuation orders. It was found that 90% of pharmacists used their prescribing authority, ordering a median of 11.3 prescriptions monthly (interquartile range 4.3-32.8). Clinical areas with the most overall prescribing included critical care (854.8), oncology and palliative care (463.0), and surgery (409.3) prescriptions per pharmacist Full-Time Equivalent per year. CONCLUSIONS: This study demonstrates a broad range of prescribing from pharmacists within acute care practice and a wide variety of medication prescribed. Future areas for research include barriers and enablers to pharmacist prescribing and examination of where prescribing pharmacists have the greatest value.

The road to pharmacist prescribing in Alberta Health Services.

PURPOSE: The implementation of policy within a health organization to support a new legislative and regulatory framework of pharmacist prescribing in the Canadian province of Alberta is described. SUMMARY: The evolution of pharmacists' practice activities to encompass medication management through independent prescribing authority has occurred in many jurisdictions around the world. In 2007, Alberta pharmacists were granted the most progressive scope of practice in all of North America. Pursuant to a series of legislative and regulatory initiatives enacted since 2000, the provincial health authority, Alberta Health Services (AHS), has worked to (1) establish a policy framework that supports pharmacist prescribing, (2) provide opportunities for pharmacist prescribing in both inpatient and ambulatory care practice environments, and (3) provide motivation and resources for AHS pharmacists to acquire "additional prescribing authorization" (APA) that enables them to independently prescribe and manage patients' ongoing drug therapy. Pharmacists with APA currently are permitted to prescribe all medications requiring a prescription, with the exception of opiates and other controlled substances; efforts to expand pharmacist prescribing to include those medications are ongoing. Currently, nearly half of all AHS pharmacists have APA. The health authority plans to make APA a standard expectation for all clinical pharmacists working in collaborative practice settings. CONCLUSION: Opportunities provided to Alberta pharmacists by legislation have been embraced by the provincial health authority. The AHS leadership remains committed to ensuring that its pharmacists practice to the full extent of their scope of practice and actively encourages and supports them in their efforts to provide optimal patient care.

Independent prescribing by hospital pharmacists: Patterns and practices in a Canadian province.

PURPOSE: Results of a survey to determine the frequency of prescribing by Canadian hospital pharmacists with independent prescribing authority are reported. METHODS: A Web-based questionnaire was used to collect data on the prescribing activities of a designated group of hospital-affiliated pharmacists in the province of Alberta who had been granted "additional prescribing authorization" (APA) through a peer-review process and were providing clinical pharmacy services in inpatient and/or outpatient settings at the time of the survey (January-March 2014). Descriptive statistics and logistic regression analysis were used to determine the median weekly frequency of prescribing, factors associated with increased use of APA, and perceived prescribing barriers and enablers. RESULTS: The survey response rate was about 50% (77 of 153 eligible pharmacists). The median self-reported number of prescriptions and medication orders written during an average week was 4.2 (interquartile range, 2.0-10.0) per 10 patients. Antibiotics and anticoagulants were the most commonly prescribed medications. Interdisciplinary care team dynamics was rated as a leading enabler of prescribing but also a leading barrier to the exercise of APA. The greatest motivators to apply for APA were the potential for increased efficiency and the potential for enhanced patient care. CONCLUSION: The survey results indicated that, in an average week, hospital pharmacists with APA prescribed for almost half of the patients they cared for as part of the interdisciplinary team. Prescribing most frequently occurred after team discussion and most often involved adjusting dosages based on organ function and clinical assessment.

Canadian Stroke Best Practice Recommendations: secondary prevention of stroke guidelines, update 2014.

Every year, approximately 62,000 people with stroke and transient ischemic attack are treated in Canadian hospitals. The 2014 update of the Canadian Secondary Prevention of Stroke guideline is a comprehensive summary of current evidence-based recommendations for clinicians in a range of settings, who provide care to patients following stroke. Notable changes in this 5th edition include an emphasis on treating the highest risk patients who present within 48 h of symptom onset with transient or persistent motor or speech symptoms, who need to be transported to the closest emergency department with capacity for advanced stroke care; a recommendation for brain and vascular imaging (of the intra- and extracranial vessels) to be completed urgently using computed tomography/computed tomography angiography; prolonged cardiac monitoring for patients with suspective cardioembolic stroke but without evidence for atrial fibrillation on electrocardiogram or holter monitoring; and de-emphasizing the need for routine echocardiogram. The Canadian Stroke Best Practice Recommendations include a range of supporting materials such as implementation resources to facilitate the adoption of evidence to practice, and related performance measures to enable monitoring of uptake and effectiveness of the recommendations using a standardized approach. The guidelines further emphasize the need for a systems approach to stroke care, involving an interprofessional team, with access to specialists regardless of patient location, and the need to overcome geographical barriers to ensure equity in access within a universal health-care system.
