RESUMEN
OBJECTIVE: To understand how lack of attachment to a regular primary care provider influences patients' outlooks on primary care, ability to address their health care needs, and confidence in the health care system. DESIGN: Qualitative descriptive study using semistructured interviews. SETTING: Canadian provinces of Nova Scotia, Ontario, and Quebec. PARTICIPANTS: Patients aged 18 years or older who were unattached or had become attached within 1 year of being interviewed and who resided in the province in which they were interviewed. METHODS: Forty-one semistructured interviews were conducted, during which participants were asked to describe how they had become unattached, their searches to find new primary care providers, their perceptions of and experiences with the centralized waiting list in their province, their experiences seeking care while unattached, and the impact of being unattached on their health and on their perceptions of the health care system. Interviews were transcribed and analyzed using a thematic approach. MAIN FINDINGS: Two main themes were identified in interviews with unattached or recently attached patients: unmet needs of unattached patients and the impact of being unattached. Patients' perceived benefits of attachment included access to care, longitudinal relationships with health care providers, health history familiarity, and follow-up monitoring and care coordination. Being unattached was associated with negative effects on mental health, poor health outcomes, decreased confidence in the health care system, and greater pre-existing health inequities. CONCLUSION: Having a regular primary care provider is essential to having access to high-quality care and other health care services. Attachment also promotes health equity and confidence in the public health care system and has broader system-level, social, and policy implications.

BACKGROUND: Older adults living with dementia may express challenging responsive behaviours. One management strategy is pharmacologic treatment though these options often have limited benefit, which may lead to multiple treatments being prescribed. METHODS: The aim of the present study was to describe psychoactive medication polypharmacy and explore factors associated with psychoactive polypharmacy in a cohort of older adults living with dementia in Nova Scotia, Canada, including a gender-stratified analysis. This was a retrospective cohort study of those aged 65 years or older with a recorded diagnosis of dementia between 2005 and 2015. Medication dispensation data was collected from April 1, 2010, or dementia diagnosis (cohort entry) to either death or March 31, 2015 (cohort exit). Psychoactive medication claims were captured. Psychoactive medication polypharmacy was defined as presence of three or more psychoactive prescription medications dispensed to one subject and overlapping for more than 30 days. Psychoactive polypharmacy episodes were described in duration, quantity, and implicated medications. Regression analysis examined factors associated with experience and frequency of psychoactive polypharmacy. All analysis were stratified by gender. RESULTS: The cohort included 15,819 adults living with dementia (mean age 80.7 years; 70.0% female), with 99.4% (n = 15,728) receiving at least one psychoactive medication over the period of follow-up. Psychoactive polypharmacy was present in 19.3% of the cohort. The gender specific logistic regressions demonstrated that for both men and women a younger age was associated with an increased risk of psychoactive polypharmacy (women: OR 0.97, 95%CI[0.96, 0.98], men: OR 0.96, 95%CI[0.95, 0.97]). Men were less likely to experience psychoactive polypharmacy if their location of residence was urban (OR 0.86, 95%CI[0.74, 0.99]). There was no significant association between location of residence (urban or rural) and psychoactive polypharmacy for women living with dementia. Antidepressants were the most dispensed medication class, while quetiapine was the most dispensed medication. CONCLUSIONS: This study suggests that of adults living with dementia those of younger ages were more likely to experience psychoactive polypharmacy and that men living with dementia in rural locations may benefit from increased access to non-pharmacological options for dementia management.

Background: A history of medical abuse and social inequality confounded by persistent racial discrimination in health care has triggered mistrust between Black patients and health care providers. Although the consequences of systemic racism on health outcomes are well understood, little is known about how they manifest in pharmacy practice. The objective of this study was to explore the experiences of Black Nova Scotians with community pharmacists. Methods: This was a qualitative study that used focus groups and one-on-one interviews. Black Nova Scotians 18 years of age and older who have had interactions with community pharmacists were invited to participate. Focus groups and interviews were audio-recorded, transcribed and analyzed thematically. Results: Two focus groups (n = 10) and 6 one-on-one interviews were held between May and June 2021. Three major themes were identified: 1) difficulties navigating a pharmacy as a Black person, 2) lack of inclusivity and cultural competence in the pharmacy and 3) transactional relationships with pharmacists. Discussion: Most participants felt their race negatively affected the quality of care they received from the pharmacist and that pharmacists were not culturally competent. Most participants did not consider pharmacists to be part of their health care team and described feeling unsafe or uncomfortable in the pharmacy. Conclusions: Pharmacists have an important role in closing the health equity gap. This research highlights the need for pharmacy education to include cultural competence and will be used to guide strategies to improve access to culturally safe pharmacy services for Black Nova Scotians.
RESUMEN
Background: Throughout the COVID-19 pandemic, community pharmacists have played an important role in the provision of patient care, including the delivery of COVID-19 vaccines. The additional workload and related demands arising from these extended services might affect worklife burnout. This qualitative study explored the experiences of Canadian community pharmacists in providing COVID-19 vaccines during the COVID-19 pandemic. Methods: Eighteen community pharmacists across 10 provinces were asked about vaccination processes and perceptions about their role in separate, virtual semistructured interviews. Interviews were transcribed verbatim and analyzed using a deductive approach using the Areas of Worklife Burnout framework, with pharmacists' self-reported descriptions of their activities summarized using the Association of Faculties of Pharmacy of Canada's (AFPC) professional competencies framework. Results: Participants identified aspects of their role that were rewarding and challenging. Some challenges included lack of control, increased workload, inadequate communication, unfair treatment and conflicting values. They described being able to meet challenges and demonstrating resiliency via adaptability, developing communities and valuing their contribution to ending the COVID-19 pandemic. Self-identified AFPC competencies contributing to their ability to manage their worklife included care-provider, professional, leader-manager, collaborator and scholar. Conclusion: Pharmacists accepted their additional responsibility of managing COVID-19 vaccines during the COVID-19 pandemic. However, they expressed some challenges with this role. To ensure sustainability of these services, prioritizing adequate resources, work processes and efficient communication with all relevant stakeholder groups, including public health, government and corporate leaders, is recommended for the future.

RESUMEN
BACKGROUND: Prescribing cascades are a source of inappropriate prescribing for older adults with dementia. We aimed to study three prescribing cascades in older Nova Scotians with dementia using administrative databases. METHODS: Cohort entry for Nova Scotia Seniors' Pharmacare Program beneficiaries was the date of dementia diagnosis. Prescription drug dispensing data was extracted for inciting medication and second treatment (cholinesterase inhibitor and bladder anticholinergic, metoclopramide and Parkinson's disease medication, or calcium channel blocker (CCB) and diuretic) over the six-year period April 1, 2009 to March 31, 2015. In three separate analyses, dispensing an inciting medication signaled a look back of 365 days from the date of first dispensing to confirm that the second treatment was started after the inciting medication. The prescribing cascade was considered when the second treatment was started within 180 days of the inciting treatment. Sex differences in the prescribing cascade were tested using t-tests or chi square tests as appropriate. Both univariate (unadjusted) and multivariate (adjusted) logistic regression (adjusted for age, rurality, and sex) and Cox proportional hazards regression was used to identify risk factors for the prescribing cascade. RESULTS: From March 1, 2005 to March 31, 2015, 28,953 Nova Scotia Seniors' Pharmacare beneficiaries with dementia (NSSPBD) were identified. There were 60 cases of bladder anticholinergics following cholinesterase inhibitors, 11 cases of Parkinson's disease medication following metoclopramide, and 289 cases of a diuretic following CCB in the cohort. Regression analysis demonstrated that risk of bladder anticholinergics following cholinesterase inhibitors and diuretics following CCBs were associated with female sex. Cox regression suggested that bladder anticholinergics were less often used by those on cholinesterase inhibitors and did not identify CCB use as leading more frequently to diuretic use. CONCLUSIONS: The combination of diuretics following CCB was the most common prescribing cascade and bladder anticholinergics following cholinesterase inhibitors the second most common. However, exposure to the inciting medications did not increase risk of exposure to the second treatments. Combinations of bladder anticholinergics following cholinesterase inhibitors and diuretics following CCBs were more common for women raising concern that women may be at increased risk of these prescribing cascades.

BACKGROUND: Concurrent use of 2 nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors, loop diuretics, angiotensin-converting enzyme inhibitors, or anticoagulants is considered potentially inappropriate by Screening Tool of Older Persons' Prescriptions and Screening Tool to Alert to Right Treatment criteria. OBJECTIVE: The objective was to examine drug duplication in a cohort of older adults with dementia. METHODS: Cohort entry for Nova Scotia Seniors' Pharmacare Program beneficiaries was the date an International Classification of Diseases ninth edition or 10th edition code for dementia was recorded in accessed databases between March 1, 2005, and March 31, 2015. Medication dispensation and sociodemographic data were captured from the Nova Scotia Seniors' Pharmacare Program database between April 1, 2010, and March 31, 2015. Duplication was considered when 2 drugs from the same class were dispensed such that the supply in the patient's possession could overlap for more than 30 days. We reported number of cases of duplication and duration of overlap. Sex differences in drug duplication were assessed with bivariate logistic regression. RESULTS: In the cohort of 28,953 Nova Scotia Seniors' Pharmacare Program beneficiaries with dementia, we documented concurrent use in 101 (1.7%) nonsteroidal anti-inflammatory drugs users (mean durationâ¯=â¯75.6 days), 95 (1.0%) selective serotonin reuptake inhibitors users (mean durationâ¯=â¯146.6 days), 5 (0.07%) loop diuretic users (mean durationâ¯=â¯530.6 days), 183 (2.0%) angiotensin-converting enzyme inhibitor users (mean durationâ¯=â¯123.9 days), and 160 (3.5%) anticoagulant users (mean durationâ¯=â¯63.6 days). Nonsteroidal anti-inflammatory drug pairs were most commonly celecoxib with naproxen or diclofenac. Selective serotonin reuptake inhibitors duplication was most commonly sertraline with citalopram. No sex differences in risk for drug duplication were identified. CONCLUSIONS: Drug duplication was identified in a cohort of older adults with dementia and is a feasible target for intervention.

RESUMEN
OBJECTIVE: This article describes the evaluation of the experiences and needs of users of the Drug Information Resources (DIR) website. The DIR website attracts traffic and use from around the world, with the highest number of users in Canada and the United States. METHODS: An online questionnaire was developed through use of a literature review and Google Analytics data. Face validity testing and test-retest reliability were completed prior to releasing the questionnaire. RESULTS: Although the Google Analytics data showed that the site is used internationally, most respondents were Canadian students. They used the site for academic and clinical purposes and reported it was easy to use, was well organized, and included required resources, and they would recommend it to others. CONCLUSION: The DIR website was found to be a valuable resource for educational and clinical use. Future studies will aim to obtain input from international users.

BACKGROUND: Influenza is a serious public health concern, resulting in morbidity, mortality and significant expense to healthcare systems worldwide. Annual vaccination is the most effective way to prevent influenza. The National Advisory Committee on Immunization in Canada recommends that everyone six months of age and older without contraindications should be vaccinated. The Canadian province of Nova Scotia implemented a publicly-funded universal influenza vaccination program in the 2010-2011 influenza season. In 2013, pharmacists in Nova Scotia gained the authority to provide a variety of vaccinations, including the publicly-funded influenza vaccine. This study aimed to investigate any changes in influenza vaccine coverage following the implementation of each policy change: 1) universal publicly-funded program and 2) universal publicly-funded program with the addition of pharmacists. METHODS: Influenza seasons evaluated were from 2006-2007 to 2015-2016. Coverage was estimated by examining Nova Scotia census data with aggregate immunization administration data, including the total number of vaccinations administered according to vaccine provider (physician, public health or pharmacist), geographic region, vaccine recipient age and year. RESULTS: The analysis showed an increase in influenza vaccine coverage immediately following the implementation of the two studied policy changes. Vaccine coverage increased from 36.4 to 38% following the implementation of the universally funded vaccine policy. Following the implementation of pharmacists as immunizers, coverage increased from 35.7 to 41.7%. Vaccine coverage was highest in those 65 years of age and older during all years evaluated. Physicians provided the highest proportion of vaccines during all study periods, however a decreasing trend through all periods was observed. Physicians proportionately provided more vaccines in urban areas; whereas pharmacist and public health immunization providers in rural areas provided proportionately more vaccinations than their urban counterparts. CONCLUSIONS: The addition of a universally funded vaccination policy and the addition of pharmacists as providers of the influenza vaccine resulted in increases in vaccine coverage initially. Additional research is needed to determine the long-term impacts of the policy changes on vaccination coverage and to identify other important factors affecting vaccine uptake.

BACKGROUND: Falls and the resulting complications are common among frail older adults. We aimed to explore risk factors and potential prevention strategies for falls in elderly residents of Long-Term Care Facilities (LTCF). METHODS: This was a cross sectional study design using data from the Care by Design (CBD) study, within Nova Scotia's Capital District Health Authority. This observational time series cohort study collected data before, during and after the implementation of CBD, a new model of coordinated primary care in LTCF. Here, we analyzed data collected after the implementation of CBD (September 1, 2011- February 28, 2012). RESULTS: Falls were frequent; 56.2% of our sample of 395 residents fell at least once. In univariate analyses, male gender (p = 0.009), dementia (p = 0.005), and use of Selective Serotonin Reuptake Inhibitors or Selective Serotonin-Norepinepherine Reuptake Inhibitors (SSRI/SNRI) (p = 0.084) showed statistically significant associations with having fallen. Benzodiazepine use appeared to be protective for falls (p = 0.058). In a fully adjusted multivariable linear regression model, dementia (ß coefficient 0.96, 95% CI: 0.83,1.84; p = 0.032), visual impairment (ß 0.84, 95% CI: 0.13,1.56; p = 0.021), and use of any PIMs (ß 0.34, 95% CI: 0.037,0.65; p = 0.028) were associated with increased risk of having fallen. Benzodiazepine use remained associated with reduced numbers of falls (p = 0.009), and SSRI/SNRI use was associated with increased numbers of falls (p = 0.007). Male gender was associated with increased falls in the model which excluded frailty (p = 0.022), though gender lost statistical significance once frailty was added to the model (p = 0.06). CONCLUSIONS: In our sample of LTCF residents, falls were common. Cognitive impairment, male gender, visual impairment, PIM use and use of SSRI/SNRI medications were associated with increased risk of falls, while benzodiazepine use appeared to be associated with a decreased risk of having fallen. Falls remain an important problem among LTC residents. Screening for falls during patient encounters is recommended, along with further research to identify risk factors and target interventions.

BACKGROUND: Preterm infants often receive blood transfusions during hospitalization. Although transfusions are intended to enhance oxygen delivery, previous studies found decreases in tissue and mesenteric oxygen saturation during and after blood transfusions without changes in vital signs and hemoglobin oxygen saturation. PURPOSE: To study the effect of blood transfusions on regional mesenteric tissue oxygen saturation (rSO2), hemoglobin saturation of oxygen (SpO2), and heart rate (HR) in premature infants. METHOD: A prospective, observational, nonrandomized study using a repeated-measures design was done to evaluate changes in physiologic variables (HR, SpO2, rSO2) before, during, and after a blood transfusion in premature infants. RESULTS: A convenience sample of 30 infants with a mean gestational age of 25.5 (2.1) weeks was recruited. Repeated-measures analysis of variance found no significant differences in HR (P = .06) and SpO2 (P = .55) over time. However, significant differences occurred in rSO2 over the 3 time periods (P < .001). The rSO2 increased during the transfusion from 40.3% to 41.5%, but decreased to 34.9% in the posttransfusion period. Pairwise comparisons revealed statistically significant mean rSO2 differences between pretransfusion and posttransfusion (P < .001), and during transfusion to posttransfusion (P < .001) periods. IMPLICATIONS FOR RESEARCH: This study supports previous findings of perfusion changes during blood transfusions in preterm infants. IMPLICATIONS FOR PRACTICE: Measuring mesenteric tissue oxygenation during blood transfusion in very low-birth-weight infants can potentially add another physiologic parameter to guide further clinical assessment and interventions during transfusions.

Needle fear typically begins in childhood and represents an important health-related issue across the lifespan. Individuals who are highly fearful of needles frequently avoid health care. Although guidance exists for managing needle pain and fear during procedures, the most highly fearful may refuse or abstain from such procedures. The purpose of a clinical practice guideline (CPG) is to provide actionable instruction on the management of a particular health concern; this guidance emerges from a systematic process. Using evidence from a rigorous systematic review interpreted by an expert panel, this CPG provides recommendations on exposure-based interventions for high levels of needle fear in children and adults. The AGREE-II, GRADE, and Cochrane methodologies were used. Exposure-based interventions were included. The included evidence was very low quality on average. Strong recommendations include the following. In vivo (live/in person) exposure-based therapy is recommended (vs. no treatment) for children seven years and older and adults with high levels of needle fear. Non-in vivo (imaginal, computer-based) exposure (vs. no treatment) is recommended for individuals (over seven years of age) who are unwilling to undergo in vivo exposure. Although there were no included trials which examined children < 7 years, exposure-based interventions are discussed as good clinical practice. Implementation considerations are discussed and clinical tools are provided. Utilization of these recommended practices may lead to improved health outcomes due to better health care compliance. Research on the understanding and treatment of high levels of needle fear is urgently needed; specific recommendations are provided.

OBJECTIVES: Community pharmacists play an important role in primary care access and delivery for all patients, including patients with a family physician or nurse practitioner ("attached") and patients without a family physician or nurse practitioner ("unattached"). During the COVID-19 pandemic, community pharmacists were accessible care providers for unattached patients and patients who had difficulty accessing their usual primary care providers ("semi-attached"). Before and during the pandemic, pharmacist services expanded in several Canadian provinces. The aim of this qualitative study was to explore patient experiences receiving care from community pharmacists, and their perspectives on the scope of practice of community pharmacists. METHODS: Fifteen patients in Nova Scotia, Canada, were interviewed. Participant narratives pertaining to pharmacist care were analyzed thematically. KEY FINDINGS: Attached, "semi-attached," and unattached patients valued community pharmacists as a cornerstone of care and sought pharmacists for a variety of health services, including triaging and system navigation. Patients spoke positively about expanding the scope of practice for community pharmacists, and better optimization of pharmacists in primary care. CONCLUSIONS: System decision-makers should consider the positive role community pharmacists can play in achieving primary care across the Quintuple Aim (population health, patient and provider experiences, reducing costs, and supporting equity in health).

BACKGROUND: Sedative-hypnotic drugs are often initiated in hospital to manage insomnia and anxiety. Guidelines discourage their use, particularly in older adults, due to risks of falls, fractures, and delirium. AIM: To identify publicly available resources to decrease the use of sedative-hypnotic drugs and promote sleep in hospital. METHOD: An advanced Google search with 6 search strategies was conducted. Key websites were also identified and searched. Hospital- or community-based resources using non-pharmacologic measures to reduce sedative-hypnotic drug use and/or to promote sleep were included if they were publicly available in English within the past 5 years. Full text screening and data extraction was performed independently by 2 reviewers; a third reviewer resolved disagreements by consensus. RESULTS: A total of 79 resources met inclusion criteria, with 65 (82.3%) providing education and 31 (39.2%) describing sleep hygiene strategies. Other resources included deprescribing (17, 21.5%), relaxation training (13, 16.5%), cognitive behavioural therapy for insomnia (9, 11.4%), and policies (7, 8.9%). The resources primarily targeted patients (59, 74.7%) followed by healthcare providers (9, 11.4%). There were 9 resources (11.4%) that applied to both community and hospital settings, and another 2 (2.5%) designed specifically for hospital. CONCLUSION: Many resources were available to patients and healthcare providers to reduce inappropriate or ineffective use of sedative-hypnotic drugs and promote better sleep. Specific resources for the hospital setting were infrequent and recommended that clinicians stop hospital-initiated sedatives when patients are discharged. Identified resources can be adapted by healthcare organizations to develop sedative-hypnotic prescribing programs and policies.

Introduction: Prescribing cascade refers to use of a medication to treat a drug-related adverse event. Prescribing cascades increase medication use, cost, and risk of adverse events. Objective: Our objective was to use administrative health data to identify whether use of medications from the anticholinergic cognitive burden scale was associated with proton pump inhibitor (PPI) prescribing consistent with a prescribing cascade in older adults with dementia. Method: The cohort was comprised of Nova Scotia Seniors' Pharmacare beneficiaries identified to have dementia and medication dispensation data recorded between 1 April 2010, or cohort entry and 31 March 2015. Anticholinergic medications from the anticholinergic cognitive burden scale (ACB) were abstracted. A look back period of 365 days identified if a PPI had been dispensed preceding anticholinergic dispensation. PPI initiation within 30, 60, 90, or 180 days of the anticholinergic medication was assessed. Demographic description of those dispensed anticholinergic medications or PPIs were reported. Risk factors for the prescribing cascade were investigated with logistic regression and Cox proportional hazards modelling including a sex-stratified analysis. Results: We identified 28,952 Nova Scotia Seniors' Pharmacare beneficiaries with dementia and prescription dispensation data. Anticholinergic medications were frequently dispensed with 63.4% of the cohort dispensed at least one prescription for an anticholinergic medication. The prescribing cascade defined as up to 180-days between anticholinergic medication inititation and PPI dispensation, occurred in 1,845 Nova Scotia Seniors' Pharmacare beneficiaries with dementia (incidence 6.4%). Multivariate regression showed those experiencing the prescribing cascade after initiating any anticholinergic were younger (OR 0.98, 95%CI [0.97-0.98]), less likely to live in an urban location (OR 0.82, 95%CI [0.74-0.91]), or to be men (OR 0.74, 95%CI [0.67-0.82]). Cox regression demonstrated an increased risk of starting a PPI within 180 days when initiating any medication from the ACB (HR 1.38, 95%CI [1.29-1.58]). Discussion: Regression modelling suggested that anticholinergic medications increased the risk of PPI dispensation consistent with a prescribing cascade in the cohort. The identification of the prescribing cascade in this population of older Nova Scotia Seniors' Pharmacare Program beneficiaries with dementia using administrative health data highlights how routinely collected health data can be used to identify prescribing cascades.
RESUMEN
BACKGROUND: Benzodiazepines and sedative-hypnotic drugs (BZD/SHD) are commonly utilized in the acute care setting for insomnia and anxiety and are associated with cognitive impairment, falls, and fractures. Interventions to reduce use of BZD/SHD in hospitals are not well characterized. OBJECTIVE: The objective was to conduct a scoping review to identify and characterize interventions to reduce the use of BZD/SHD by adults in the acute care setting. METHODS: English language studies and abstracts that described an intervention to reduce BZD/SHD in adult hospital patients were included. Six databases (PubMed, EMBASE, CINAHL, PsycINFO, Scopus, and Web of Science) were searched up to July 2018 and updated to February 3, 2021. The grey literature (Opengrey, Grey Matters, Google Advanced) was searched up to July 2018. Titles and abstracts were screened and full-text articles were reviewed and charted by three independent reviewers. Stakeholders were consulted to inform the scoping review and collect perspectives on the findings. RESULTS: There were 13,046 records identified and 43 studies included. The most common study designs were uncontrolled before and after (23/43, 53.5%) and randomized controlled trials (7/43, 16.3%). The majority of studies tested a single intervention (32/43, 74.4%) such as education, deprescribing, relaxation training and sleep protocols. Patients were frequently the target of relaxation training and behavior change interventions; while sleep protocols, multifaceted interventions, education and deprescribing were usually directed at healthcare providers, either alone or in combination with patients. Most studies reported positive results in decreasing BZD/SHD use (27/43, 62.8%). CONCLUSIONS: The scoping review found a variety of interventions to decrease the utilization of BZD/SHD in hospitals. Multifaceted interventions aimed at patients and healthcare providers that include a combination of education, sleep protocols, and deprescribing may support reductions in BZD/SHD use. Stakeholders also recommended policy and system changes such as computer alerts due to feasibility and workload.
