Pilot study evaluating feasibility and utility of pharmacist-driven oral antineoplastic agent monitoring program.

INTRODUCTION: Oncologists are increasingly prescribing oral antineoplastic agents which have benefits and challenges impacting patient outcomes. Practice guidelines recommend monitoring symptoms and adherence without outlining any specific tools or methods for monitoring. Pharmacists are successful in monitoring patients on therapy and improving outcomes. We aimed to assess the feasibility and utility of a pharmacist-delivered and medical record-integrated adherence and symptom monitoring program for patients on oral antineoplastic agents. METHODS: This single-center, prospective, interventional study designed and implemented an adherence and monitoring program. A pharmacist contacted patients twice between clinic visits for three months. During telephone encounters, patients were verbally screened for medication adherence and assessed for new or changing symptoms using the Edmonton Symptom Assessment System as a signal of possible adverse events. We measured feasibility via patient enrollment, completed proportion of scheduled contacts, and pharmacist time. Utility was assessed through patient adherence, satisfaction surveys, healthcare resource utilization, and pharmacist interventions (i.e., patient education, adherence assistance, and symptom management). RESULTS: Fifty-one patients participated. Ninety-one percent of scheduled patient contacts were completed. Edmonton Symptom Assessment System was administered by pharmacy personnel 102 times. Patient-reported adherence was 100%. Overall satisfaction was 85% and 100%, for patients and physicians, respectively. Fifty-one (98%) pharmacist recommendations were accepted. There were 14 total utilizations of healthcare resources-5.2 per 1000 patient days. CONCLUSIONS: This study suggests a pharmacist monitoring program for patients taking oral antineoplastic agents is feasible and provides utility. Further research is needed to evaluate whether this program improves safety, adherence, and outcomes in patients using oral antineoplastic agents.

Local Control Following Stereotactic Body Radiation Therapy for Liver Oligometastases: Lessons from a Quarter Century.

The utilization of stereotactic body radiation therapy for the treatment of liver metastasis has been widely studied and has demonstrated favorable local control outcomes. However, several predictive factors play a crucial role in the efficacy of stereotactic body radiation therapy, such as the number and size (volume) of metastatic liver lesions, the primary tumor site (histology), molecular biomarkers (e.g., KRAS and TP53 mutation), the use of systemic therapy prior to SBRT, the radiation dose, and the use of advanced technology and organ motion management during SBRT. These prognostic factors need to be considered when clinical trials are designed to evaluate the efficacy of SBRT for liver metastases.

Development and implementation of a postgraduate medical education-wide initiative in quality improvement and patient safety.

BACKGROUND: Quality improvement and patient safety (QIPS) have been assigned a higher profile in CanMEDS 2015, CanMEDS-Family Medicine 2017 and new accreditation standards, prompting an initiative at Dalhousie University to create a vision for integrating QIPS into postgraduate medical education. OBJECTIVE: The purpose of this study is to describe the implementation of a QIPS strategy across residency education at Dalhousie University. METHODS: A QIPS task force was formed, and a literature review and needs assessment survey were completed. A needs assessment survey was distributed to all Dalhousie residency programme directors. 12 programme directors were interviewed individually to collect additional feedback. The results were used to develop a 'road map' of recommendations with a graduated timeline. RESULTS: A task force report was released in February 2018. 46 recommendations were developed with a timeframe and responsible party identified for each. Implementation of the QIPS strategy is underway, and evaluation and challenges faced will be described. CONCLUSIONS: We have developed a multiyear strategy that is available to provide guidance and support to all programmes in QIPS. The development and implementation of this QIPS framework may serve as a template for other institutions who seek to integrate these competencies into residency training.

Hemostatic Efficacy and Safety of 4-Factor Prothrombin Complex Concentrate in Doac-Associated Intracranial Hemorrhage.

Background: Factor Xa (FXa) inhibitor use has increased over the last decade and though associated rates of major bleeding are lower compared to warfarin, outcomes from intracranial hemorrhage (ICH) are still significant. Targeted FXa inhibitor reversal agent became available in 2018, however use of 4-factor prothrombin complex concentrate (4F-PCC) for FXa inhibitor-associated ICH continues at many institutions. Objective: Evaluate the safety and hemostatic efficacy of 4F-PCC for FXa inhibitor-associated ICH. Methods: Single-center, retrospective study of patients who received 4F-PCC for FXa inhibitor-associated ICH. The primary efficacy endpoint was hemostasis and thrombosis was the main safety endpoint. Secondary endpoints included in-hospital mortality and discharge disposition. Results: 76 patients on apixaban or rivaroxaban were included. Good or excellent hemostasis was achieved in 80.3% of patients. Five patients experienced a thrombotic event. Favorable discharge disposition and lower in-hospital mortality was more likely in patients who achieved excellent hemostasis. Conclusion: 4F-PCC is safe and effective for FXa inhibitor associated ICH.

The COVID-19 Data Portal: accelerating SARS-CoV-2 and COVID-19 research through rapid open access data sharing.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic will be remembered as one of the defining events of the 21st century. The rapid global outbreak has had significant impacts on human society and is already responsible for millions of deaths. Understanding and tackling the impact of the virus has required a worldwide mobilisation and coordination of scientific research. The COVID-19 Data Portal (https://www.covid19dataportal.org/) was first released as part of the European COVID-19 Data Platform, on April 20th 2020 to facilitate rapid and open data sharing and analysis, to accelerate global SARS-CoV-2 and COVID-19 research. The COVID-19 Data Portal has fortnightly feature releases to continue to add new data types, search options, visualisations and improvements based on user feedback and research. The open datasets and intuitive suite of search, identification and download services, represent a truly FAIR (Findable, Accessible, Interoperable and Reusable) resource that enables researchers to easily identify and quickly obtain the key datasets needed for their COVID-19 research.

Stop the Bleed: An Interprofessional Community Service Learning Project Assessing the Efficacy of Pharmacist-Led Hemorrhage Control Education for Laypersons.

OBJECTIVES: Stop the Bleed (STB) is a national initiative that provides lifesaving hemorrhagic control education. In 2019, pharmacists were added as health-care personnel eligible to become STB instructors. This study was conducted to evaluate the efficacy of pharmacist-led STB trainings for school employees in South Texas. METHODS: Pharmacist-led STB trainings were provided to teachers and staff in Laredo, Texas. The 60-min trainings included a presentation followed by hands-on practice of tourniquet application, wound-packing, and direct pressure application. Training efficacy was assessed through anonymous pre- and postevent surveys, which evaluated changes in knowledge, comfort level, and willingness to assist in hemorrhage control interventions. Student volunteers (predominantly pharmacy and medical students) assisted in leading the hands-on portion, providing a unique interprofessional learning opportunity. RESULTS: Participants with previous training (N = 98) were excluded, resulting in a final cohort of 437 (response rate 87.4%). Compared with baseline, comfort level using tourniquets (mean, 3.17/5 vs 4.20/5; P < 0.0001), opinion regarding tourniquet safety (2.59/3 vs 2.94/3; P < 0.0001), and knowledge regarding tourniquets (70.86/100 vs 75.84/100; P < 0.0001) and proper tourniquet placement (2.40/4 vs 3.15/4; P < 0.0001) significantly improved. CONCLUSIONS: Pharmacist-led STB trainings are efficacious in increasing school worker knowledge and willingness to respond in an emergency hemorrhagic situation.

Ankle-foot orthoses improve walking but do not reduce dual-task costs after stroke.

BACKGROUND: Cognitive-motor interference, as measured by dual-task walking (performing a mental task while walking), affects many clinical populations. Ankle-foot orthoses (AFOs) are lower-leg splints prescribed to provide stability to the foot and ankle, as well as prevent foot drop, a gait deficit common after stroke. AFO use has been shown to improve gait parameters such as speed and step time, which are often negatively impacted by dual-task walking. OBJECTIVES: Our objective was to establish whether AFOs could protect against cognitive-motor interference, as measured by dual-task walking, following post-stroke hemiplegia. METHODS: A total of 21 individuals with post-stroke hemiplegia that use an AFO completed a dual-task walking paradigm in the form of a 2 (walking with vs. without a concurrent cognitive task) by 2 (walking with vs. without an AFO) repeated-measures design. Changes to both motor and cognitive performance were analyzed. RESULTS: The results suggest that the use of an AFO improves gait overall in both single- and dual-task walking, particularly with respect to stride regularity, but there were no interactions to suggest that AFOs reduce the cognitive-motor dual-task costs themselves. A lack of differences in cognitive performance during dual-task walking with and without the AFO suggests that the AFO's benefit to motor performance cannot be attributed to task prioritization. CONCLUSIONS: These data support the use of AFOs to improve certain gait parameters for post-stroke hemiplegia, but AFOs do not appear to protect against cognitive-motor interference during dual-task walking. Future research should pursue alternate therapeutics for ameliorating task-specific declines under cognitively demanding circumstances.

Exploring pharmacy residency program director preference of pharmacy student organization membership and leadership involvement on residency candidate interview selection.

INTRODUCTION: Pharmacy student professional organization involvement and leadership are important qualifications of a pharmacy residency candidate. It is unknown if membership in specific student pharmacy organizations or types of leadership roles within these organizations are preferred by residency program directors (RPDs). The purpose of the study was to determine preference and importance of specific pharmacy student professional organization membership and leadership involvement when selecting residency candidates for an interview by RPDs. METHODS: A descriptive study was conducted using an online survey. Pharmacy RPDs with involvement in reviewing applicants for interviews were included. RPDs ranked the importance and preference of specific student professional organization membership, breadth versus depth of involvement, and leadership position held on selecting candidates for an interview. RESULTS: The survey was sent to 2084 RPDs. A total of 232 respondents met inclusion criteria and completed the survey. The majority (95.5%) of RPDs reported student membership as important, while 28.6% had preference for a specific organization. A total of 56.3% of RPDs reported student leadership as "very important" and 76.1% preferred depth over breadth of involvement. A total of 55.6% of RPDs preferred applicants with a high-level leadership position. CONCLUSIONS: Pharmacy student professional organization membership is important to RPDs when selecting residency candidates for an interview. The majority of RPDs have no preference for a specific organization, while 28.6% report a preference that affects interview selection. RPDs report leadership as important and place higher importance on depth versus breadth of involvement, with greater preference for a high-level leadership position.

Individualized Dose-Escalation of HDR Prostate Brachytherapy Implant to Decrease Required External Beam Radiation Dose: A Retrospective Feasibility Study.

PURPOSE: High-dose-rate brachytherapy (HDR-BT) is commonly combined with external beam radiation therapy (EBRT) for the treatment of localized prostate cancer. Escalating the HDR-BT dose as far as organ-at-risk (OAR) constraints allow, on a personalized basis, would allow for a reduction in EBRT dose while achieving similar total biologic equivalence. The primary objective of this study was to determine the dosimetric feasibility of escalating the HDR-BT dose from 15 Gy to 16 or 17 Gy while continuing to meet OAR constraints from the original 15 Gy plan on an individualized basis. METHODS AND MATERIALS: A total of 53 consecutive HDR-BT plans were retrospectively assessed to determine what percentage of plans could be reoptimized to deliver a dose of 16 Gy or 17 Gy, while meeting defined 15-Gy OAR constraints. Factors independently associated with dose escalation were examined. RESULTS: Thirty-nine plans (74%) and 2 plans (4%) were successfully escalated to a dose of 16 Gy and 17 Gy, respectively. Rectum V80 and urethra Dmax were independently predictive of the ability to dose escalate to 16 Gy. CONCLUSIONS: Individualized HDR-BT dose escalation beyond 15 Gy without compromising OAR constraints is dosimetrically feasible. This approach could allow for a corresponding reduction of EBRT fractions (ie, from 15 to 12 fractions) and would be beneficial in terms of resource savings for departments, convenience for patients, and potentially better tolerance of treatment with the expected reduction in biologically equivalent doses to OARs. A clinical trial is being developed to investigate the efficacy and tolerance of personalized HDR-BT/EBRT dose fractionation for localized intracapsular prostate cancer.

Surveillance Ultrasound in the Neuro Intensive Care Unit: Time to Deep Vein Thrombosis Diagnosis.

BACKGROUND/OBJECTIVES: Deep vein thrombosis (DVT) and pulmonary embolism (PE) are complications of hospitalization leading to increased morbidity and mortality. Routine surveillance ultrasound has become common practice in some intensive care units (ICU) to detect DVT early and initiate anticoagulation, preventing complications. However, initiating anticoagulants for asymptomatic DVT treatment may increase risk of hemorrhage. The objective of this study was to investigate the value of routine surveillance ultrasound in early DVT diagnosis in Neuro ICU patients. METHODS: This is a retrospective review of patients diagnosed with DVT during admission to the Neuro ICU at University Hospital from January 1, 2012, through December 31, 2017. Patients were identified through International Classification of Diseases 9th and 10th Revision codes for DVT and PE, screened for inclusion criteria, and then classified as surveillance group or symptom-driven group based on intervention received. Primary outcome was time to DVT diagnosis. Secondary outcome included clinically significant hemorrhage identified by anticoagulation treatment discontinuation for suspected hemorrhage or new or expanding hemorrhage on head computerized tomography (CT). RESULTS: A total of 116 patients were identified, with 50 included: 27 were classified as surveillance and 23 as symptom-driven. Seven patients (surveillance = 3 and symptom-driven = 4) were diagnosed with only PE and were excluded from primary outcome. Median time to DVT diagnosis was similar at 148 h for surveillance versus 172 h for symptom driven (p = 0.2). There was no difference in treatment discontinuation rates (surveillance 21% vs symptom 31%; p = 0.4). Of the 27 patients with follow-up head CT, two in the surveillance group and two in the symptom-driven group showed a new or expanding hemorrhage. CONCLUSION: Routine surveillance ultrasound did not lead to significantly earlier DVT diagnosis. Hemorrhagic events were not different between groups. Utility of surveillance ultrasound in this population should be evaluated in large, prospective trials before routine use can be recommended.

National age group trends in Clostridium difficile infection incidence and health outcomes in United States Community Hospitals.

BACKGROUND: Prior studies have demonstrated an increase in Clostridium difficile infection (CDI) incidence in the United States (U.S.) in recent years, but trends among different age groups have not been evaluated. This study describes national CDI incidence by age group over a 10-year period and mortality and hospital length of stay (LOS) among patients with CDI. METHODS: This was a retrospective analysis of the U.S. National Hospital Discharge Surveys from 2001 to 2010. Eligible patients with an ICD-9-CM discharge diagnosis code for CDI (008.45) were stratified by age: <18 years (pediatrics), 18-64 years (adults), and ≥65 years (elderly adults). Data weights were used to derive national estimates. CDI incidence was calculated as CDI discharges/1000 total discharges. Mortality and LOS were compared between age groups using chi-square or Wilcoxon rank sum tests. RESULTS: These data represent 2.3 million hospital discharges for CDI over the study period. CDI incidence was highest among elderly adults (11.6 CDI discharges/1000 total discharges), followed by adults (3.5 CDI discharges/1000 total discharges) and pediatrics (1.2 CDI discharges/1000 total discharges). The elderly also had higher rates of mortality (8.8%) compared to adults (3.1%) and pediatrics (1.4%) (p < 0.0001). In addition, median hospital LOS was highest in the elderly (8 days) compared to adults (7 days) and pediatrics (6 days) (p < 0.0001). CONCLUSIONS: CDI incidence among patients hospitalized in U.S. hospitals differed based on age group between 2001 and 2010. CDI incidence, mortality, and hospital LOS were highest in the elderly adult population.

Examining the Relationship Between Traumatic Brain Injury and Substance Use Outcomes in the Canadian Population.

BACKGROUND: The literature has opposing views regarding the magnitude of the association between substance use and TBI. Most studies have examined clinical samples which are not representative of the entire head injured population. Clinical samples provide very limited insight into TBI patients whom do not seek care. OBJECTIVES: This paper examines the associations between TBI and substance use/misuse. Its primary aim is to test whether or not individuals with a past-year TBI have higher rates of substance use/misuse than Canadians without a TBI or back and/or spine injury controls drawing on self-report population level data. METHODS: Using the 2009-2010 Canadian Community Health Survey, a nationally representative cross-sectional survey of Canadians 12 years and older, this paper assessed substance use (i.e., illicit drug use; drinking and binge drinking; current smoking) among those with a TBI, as compared to two control groups: (1) individuals with a back or spinal injury (BSI); and (2) healthy noninjured controls. Multivariate regressions (logistic and multinomial), both unadjusted and adjusting for a range of injury and sociodemographic covariates, were used in hypothesis testing. RESULTS: Those with a past-year TBI demonstrated significantly elevated rates of illicit drug use relative to non-injured Canadians. Relative to the BSI group those with a TBI were less likely to drink alcohol, did not differ in binge drinking, cigarette smoking and illicit drug use. CONCLUSION: Health care professionals working with the TBI population should integrate screening, brief intervention, and referral programming as a means to reduce future harm related to substance misuse.

The influence of verbal and spatial working memory load on the time course of the Simon effect.

The Simon effect refers to the relatively poorer response times and accuracy when responding to targets that appear in a task-irrelevant spatial location that is incongruent with the location of the correct response key, compared with targets that appear in spatially congruent locations. Like Stroop and flanker effects, the Simon effect is thought to result from conflict between an irrelevant response tendency and an intended response. Because attentional control has been linked to conflict resolution, the Simon task has been proffered as a possible tool for measuring the efficacy of executive control mechanisms. These mechanisms are also involved in working memory (WM) processes, and are thought to be responsible for maintaining information in the presence of continued processing or distraction. The present study investigated the interface between WM and attention by examining the time course of the Simon effect over the response time distributions under varying WM load conditions. Participants completed verbal 0-back, spatial 0-back, verbal 2-back, and spatial 2-back tasks. Results show that the Simon effect is diminished in high WM load tasks compared with low-load tasks, and that the Simon effect interacts with the spatial task domain such that the effect persists across the distribution of response times. In contrast, the Simon effect peaks and decays in verbal tasks. The results demonstrate that the Simon effect interacts with WM load and task domain. The results suggest that the effect is more modifiable than expected, and support a complex interface between WM and attentional control.

Traumatic brain injury and early life experiences among men and women in a prison population.

This study examined the proportion of men and women reporting previous traumatic brain injury (TBI) in an Ontario (Canada) prison sample by demographic characteristics; adverse life experiences; and criminal, drug, and alcohol use history. Using data from The Cost of Substance Abuse in Canada study based on a random sample from four Ontario prisons, this study found 50.4% of males and 38% of females reporting previous TBI. More TBIs occurred before the first crime for women than for men. Women with TBI experienced more early physical and sexual abuse than those without TBI. Additionally, this study shows high prevalence of early life experiences among persons, particularly women, with a history of TBI. Prisoners and prison staff should be educated on TBI and best practice for rehabilitation of TBI.

Natural history of hearing deterioration in intracanalicular vestibular schwannoma.

BACKGROUND: Intracanalicular vestibular schwannomas have a range of treatment options that can preserve hearing: microsurgery, stereotactic radiotherapy, and conservative observation. OBJECTIVE: To evaluate the natural course of hearing deterioration during a period of conservative observation. METHODS: A retrospective case review was performed on 47 patients with a unilateral intracanalicular vestibular schwannoma. Evaluation of growth was monitored by repeat MRI scanning. Repeated pure-tone and speech audiometry results were evaluated for subgroups of patients showing growth or no growth and by subsite location of tumor in the internal auditory canal. RESULTS: Patients had a mean follow-up of 3.6 years. Over the entire population, the pure-tone average thresholds at 0.5, 1, 2, and 3 kHz and the word recognition scores both significantly deteriorated from 38 to 51 dB HL, and from 66% to 55%, respectively. Overall, 74% of subjects with good hearing, according to the 50/50 rule, maintained hearing above this rule. There were no significant differences in hearing loss by subsite in the internal auditory canal (porus, fundus, central) or by growth status (stable, growing, shrinking). Only 6 patients showed a large hearing change. This happened early during follow-up, with relatively stable hearing after this. CONCLUSION: Hearing will deteriorate in some intracanalicular vestibular schwannomas, regardless of tumor growth. Hearing deterioration, if on a large scale, most likely occurs early in follow-up. The present results using conservative management in these tumors appear similar to those reported for stereotactic radiotherapy or microsurgery.
