Community pharmacists' expanding roles in supporting patients before and during COVID-19: An exploratory qualitative study

BACKGROUND

Timely access and attachment to a primary healthcare provider is associated with better population health outcomes. In Canada, community pharmacists are highly accessible and patients struggling to access a family physician or nurse practitioner (i.e., "unattached") may seek care from a community pharmacist. Community pharmacists took on additional roles during the COVID-19 pandemic; however, little is known about how community pharmacists managed the needs of attached and unattached patients before and during the COVID-19 pandemic.

AIM

To describe Nova Scotian community pharmacists' roles in caring for unattached patients before and during the COVID-19 pandemic and identifying barriers and facilitators to optimizing patient access.

METHOD

Semi-structured interviews with community pharmacists (n = 11) across the province of Nova Scotia (Canada) were conducted.

RESULTS

Five key themes were noted: (1) rising pressure on pharmacists to meet unique health needs of attached and unattached patients; (2) what pharmacists have to offer (e.g., accessibility, trustworthiness); (3) positioning pharmacists in the system (e.g., how pharmacists can address gaps in primary healthcare); (4) pharmacist wellbeing; and, (5) recommendations for practice post-pandemic (e.g., maintain some policy changes made during the COVID-19 pandemic).

CONCLUSION

Before and during the pandemic, community pharmacists played a significant and increasing role providing care to patients, especially unattached patients. With growing numbers of unattached patients, it is vital that community pharmacists are supported to provide services to care for the health needs of patients.

Association Between Loyalty to Community Pharmacy and Medication Persistence and Compliance, and the Use of Guidelines-Recommended Drugs in Type 2 Diabetes: A Cohort Study

Pharmacists record data on all drugs claimed and may build a personal relationship with their clients. We hypothesized that loyalty to a single pharmacy could be associated with a better quality of drug use.To assess the association between pharmacy loyalty and quality of drug use among individuals treated with oral antidiabetes drugs (OADs).This is a cohort study using Quebec Health Insurance Board data. Associations were assessed using multivariable logistic regression.New OAD users, aged ≥18 years.Individuals who filled all their prescription drugs in the same pharmacy during the first year of treatment were considered loyal. During year 2 of treatment we assessed 4 quality indicators of drug use: persistence with antidiabetes treatment, compliance with antidiabetes treatment among those considered persistent, use of an angiotensin-converting enzyme inhibitor or of an angiotensin II receptor blocker (ACEi/ARB), and use of a lipid-lowering drug.Of 124,009 individuals, 59.75% were identified as loyal. Nonloyal individuals were less likely to persist with their antidiabetes treatment (adjusted odds ratio = 0.89; 95% CI: 0.86-0.91), to comply with their antidiabetes treatment (0.82; 0.79-0.84), to use an ACEi/ARB (0.85; 0.83-0.88) and to use a lipid-lowering drug (0.83; 0.80-0.85). Quality of drug use decreased as the number of different pharmacies increased (linear contrast tests <0.001).Results underscore the important role pharmacists could play in helping their clients with chronic diseases to better manage their drug treatments. Further research is needed to determine to what extent the positive effects associated with pharmacy loyalty are specifically due to pharmacists.

Polypharmacy in multimorbid older adults: protocol for a systematic review

BACKGROUND

Polypharmacy, the concurrent use of multiple medications, consistently evokes a negative connotation, notably because it is associated with a plethora of adverse events. Nonetheless, the number of individuals exposed to polypharmacy is increasing steeply, especially for older people with multiple diseases. There is a need to carefully study the phenomenon at the population scale to full assess the associated health outcomes. Yet, this reveals a complex task because there exists no consensus indicator of polypharmacy. In fact, the definitions of polypharmacy are heterogeneous and its predisposing factors and associated outcomes are not well defined. The goal of this systematic review is to summarize the literature on polypharmacy in multimorbid individuals aged 65 years and over, targeting three objectives: (1) to identify the definitions of polypharmacy that are used in the context of multimorbidity among older individuals (≥65 years); (2) to ascertain predisposing and concurrent factors associated with polypharmacy; and (3) to describe positive and negative outcomes of polypharmacy among older individuals, including hospitalizations, mortality and costs.

METHODS

We will include publications from 2004 to 2016 that target four concepts: polypharmacy, older individuals, multimorbidity and positive/negative outcomes. The search will be performed using EBM Reviews, Embase, Global Health, MEDLINE, AgeLine, CINAHL, Health Policy Reference Center, Public Affairs Index, SocINDEX and Google Scholar. Two independent reviewers will screen the articles, extract the information and evaluate the methodological quality of included studies. The results will be presented in tables and narrative summaries will be performed. We will perform meta-analyses (objective 3) if the heterogeneity is not important.

DISCUSSION

This review will help describe the various ways of conceptualizing polypharmacy and how it is associated with health outcomes. We have selected outcomes most relevant for public surveillance performed with administrative databases. Other positive and negative outcomes have been associated with polypharmacy but may not be included in the review.

Important treatment gaps in vascular protection for the elderly after type 2 diabetes therapy initiation

BACKGROUND

Canadian practice guidelines recommend the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) for vascular protection in individuals with diabetes who are at high risk of cardiovascular events, including those ≥ 65 years. We estimated the proportion of elderly persons who initiated an ACEI or an ARB in the year after beginning oral antidiabetes (OAD) treatment, and we identified factors associated with this initiation.

METHODS

Using the Quebec Health Insurance Board (RAMQ) databases, we conducted a population-based cohort study of individuals ≥ 65 years recently prescribed an OAD. We excluded those who were already taking an ACEI or ARB. Factors associated with ACEI or ARB initiation were identified using multivariate logistic regression.

RESULTS

Among 43,700 individuals, 13,621 (31.2%) initiated an ACEI or ARB in the year after beginning OAD. Individuals were more likely to begin an ACEI or an ARB if they initially received both metformin and a sulfonylurea, lived in a rural region, began OAD treatment between 2001 and 2006, were hospitalized, or had ≥ 22 medical visits in the year before OAD initiation. Individuals ≥ 75 years, those who were prescribed an OAD by a general practitioner, initially received a sulfonylurea, or received ≥ 4 different medications in the year before OAD initiation were less likely to begin an ACEI or ARB.

CONCLUSIONS

In the elderly not already taking ACEIs or ARBs, a low proportion of those undertaking OAD treatment are prescribed the recommended cardioprotection of an ACEI or ARB in the following year. Interventions are needed to close this treatment gap.

Pharmacy Record Registration of Acetyl Salicylic Acid (ASA) Prescriptions in Quebec

Purpose: To determine the extent of which acetyl salicylic acid (ASA) use is included in patients’ pharmacy records. Methods: During an in-home interview, people aged ≥65 years were asked to report all of the medications they had used at least once, including over-the-counter drugs, during the preceding month. Researchers recorded information on the drug name, reason for its use, and whether a physician prescribed it. From the pharmacy records, the drug names, prescription fill dates, quantities supplied, and the numbers of days’ supply were recorded. The level of agreement for ASA use across data sources was assessed using proportions of agreement and kappa coefficients. Results: Of 193 individuals interviewed, 86 reported the use of ASA, including 76 ASA users (88.4%) who said it was prescribed by a physician. Pharmacy medication records indicated that there were 74 users of ASA. The proportion of agreement for ASA use was 93.8%, and kappa coefficient was 0.87 (95% confidence interval: 0.80-0.94). The sensitivity, specificity, and positive predictive value of the pharmacy data were all high. Conclusions: A large proportion of ASA use is documented in pharmacy records in Quebec. Thus, the information regarding ASA use in pharmacy records is reliable. This result may not be reproducible in other settings where pharmaceutical reimbursement rules are different. This article is open to POST-PUBLICATION REVIEW. Registered readers (see “For Readers”) may comment by clicking on ABSTRACT on the issue’s contents page.

Trends in Hospital Visits for Generic and Brand-Name Warfarin Users in Québec, Canada: A Population-Based Time Series Analysis

BACKGROUND

Federal standards authorize the commercialization of generic medicines after bioequivalence versus the brand-name originator has been demonstrated. For drugs with narrow therapeutic indexes, such as warfarin, the accepted difference in bioavailability is ≤ 10%. No systematic pharmacovigilance studies are conducted once generics become available.

OBJECTIVE

We aimed to assess the impact of the arrival of generic warfarin on hospital visit trends (hospital admissions or emergency room consultations) in warfarin users.

METHODS

This was an observational interrupted time series analysis (2 January 1996 to 1 January 2016). Using the Québec Integrated Chronic Disease Surveillance System, we included all patients who were aged ≥ 66 years, publicly covered and using brand-name or generic warfarin (N = 280,158). We estimated rates of hospital visits in 6-month periods, 5 years before and up to 15 years after the arrival of generic warfarin. Periods before and after were compared using segmented regression models for all users along with exploratory (generic vs. brand name)/subgroup analyses (cardiovascular comorbidities and socioeconomic status).

RESULTS

Generic warfarin arrived on the market on 2 January 2001. Over the 20-year period of the study, the mean rate of hospital visits was 113 for 100 brand-name or generic users per 6-month period and was similar before and after the arrival of the generics. Up to 15 years after the arrival of the generics, the rates of hospital visits were 10% higher for generic than for brand-name users, which was confirmed by subgroup analyses.

CONCLUSIONS

Overall, we observed no impact on hospital visits after the arrival of generic warfarin in all the population treated with any type of warfarin. However, a higher crude rate of hospital visits among generic users than brand-name users remains to be validated using a different methodology and specific outcomes.

Depression but not non-persistence to antidiabetic drugs is associated with mortality in type 2 diabetes: A nested case-control study

AIMS

To measure the effect of depression on mortality of individuals newly treated with antidiabetic drugs, accounting for non-persistence to treatment.

METHODS

We conducted a nested case-control study within a cohort of newly treated individuals with diabetes. Using Quebec administrative data, we identified all-cause, diabetes-related, cardiovascular-related and major cardiovascular event deaths during a maximum follow-up of eight years. Each case was matched with up to 10 controls by age, sex, follow-up, and comorbidity index. We used conditional logistic regressions to estimate the effect of depression on mortality, adjusting for non-persistence to antidiabetic drug treatment, and other variables.

RESULTS

We retrieved 13,558 deaths, of which 3,652 were related to cardiovascular diseases, 2,112 to major cardiovascular events, and 311 to diabetes. Depression was associated with an increased risk of all-cause and cardiovascular-related deaths, with adjusted odds ratios (ORs) ranging from 1.32 (95% CI: 1.21-1.45) to 1.72 (95% CI: 1.57-1.88) depending on the model, but not with diabetes-related mortality.

CONCLUSION

Depression is independently associated with all-cause and cardiovascular-related mortality in individuals with type 2 diabetes, even when adjusting for non-persistence to antidiabetic drug treatment. Identifying risk factors for depression and implementing a screening and proper treatment for depression may help reducing mortality.

Did Generic Clopidogrel Commercialization Affect Trends of ER Consultations and Hospitalizations in the Population Treated with Clopidogrel?

BACKGROUND

Clopidogrel has been widely used to prevent atherothrombotic events. Since 2011, pharmacists have offered their patients the opportunity to switch to generic clopidogrel, an economic alternative. Whether bioequivalence of generic cardiovascular drugs translates into clinical equivalence at a population level remains unclear and needs to be further documented.

OBJECTIVE

We aimed to evaluate the impact of generic clopidogrel commercialization on adverse events (AEs): hospitalizations or emergency room (ER) consultations.

METHODS

This is an interrupted time series analysis using the Quebec Integrated Chronic Disease Surveillance System. We included all patients ≥ 66 years old who were users of the brand-name clopidogrel or a generic version (n = 6) 24 months before and up to 12 months after generics commercialization. Rates of AEs were computed, and periods before and after generics commercialization were analyzed by segmented regression models along with exploratory analyses (generic vs. brand name). Sensitivity analyses were also performed using stratification of the time series by (1) sex, (2) the number of prevalent cardiovascular comorbidities, and (3) socioeconomic status.

RESULTS

Time series were constituted of 89,525 clopidogrel users (mean age 78 years, 45% women, 71% ischemic heart disease, 34% stroke). For all users, there was a mean rate of 157 AEs per 1000 user-months, stable trend before (-0.1% [95% confidence interval -0.3 to 0.1] and after (0.0% [- 0.5 to 0.6]) generics commercialization. In exploratory analyses, once generic clopidogrel versions were commercialized, rates of AEs were 19.2% (95% CI 11.7-26.7) higher for generic versus brand-name users. This difference persisted up to 1 year. Sensitivity analyses yielded similar results.

CONCLUSIONS

The population treated with clopidogrel had similar rates of hospitalizations or ER consultations before and after generics commercialization. However, differences in rates of hospitalizations or ER consultations between generic and brand-name clopidogrel users may represent a drug safety signal which remains to be validated. Using a different study design, permitting adjustment for potential confounders, could be useful in this regard.

Revisiting the internal consistency and factorial validity of the 8-item Morisky Medication Adherence Scale

Objective:

To assess the internal consistency and factorial validity of the adapted French 8-item Morisky Medication Adherence Scale in assessing adherence to noninsulin antidiabetic drug treatment.

Study Design and Setting:

In a cross-sectional web survey of individuals with type 2 diabetes of the Canadian province of Quebec, self-reported adherence to the antidiabetes drug treatment was measured using the Morisky Medication Adherence Scale-8. We assessed the internal consistency of the Morisky Medication Adherence Scale-8 with Cronbach’s alpha, and factorial validity was assessed by identifying the underlying factors using exploratory factor analyses.

Results:

A total of 901 individuals completed the survey. Cronbach’s alpha was 0.60. Two factors were identified. One factor comprised five items: stopping medication when diabetes is under control, stopping when feeling worse, feeling hassled about sticking to the prescription, reasons other than forgetting and a cross-loading item (i.e. taking drugs the day before). The second factor comprised three other items that were all related to forgetfulness in addition to the cross-loading item.

Conclusion:

Cronbach’s alpha of the adapted French Morisky Medication Adherence Scale-8 was below the acceptable value of 0.70. This observed low internal consistency of the scale is probably related to the causal nature of the items of the scale but not necessarily a lack of reliability. The results suggest that the adapted French Morisky Medication Adherence Scale-8 is a two-factor scale assessing intentional (first factor) and unintentional (second factor) non-adherence to the noninsulin antidiabetes drug treatment. The scale could be used to separately identify these outcomes using scores obtained on each of the sub-scales.

Swallowing the pill of adverse effects: A qualitative study of patients' and pharmacists' experiences and decision-making regarding the adverse effects of chronic pain medications

Introduction

Pharmacological treatments of chronic pain can lead to numerous and sometimes serious adverse effects. Drawing on a social science approach to chronic illness, this study aimed to understand the experiences of people living with chronic pain and community pharmacists regarding the definition, prevention and management of analgesic adverse effects.

Methods

This qualitative study proceeded through 12 online focus groups (FGs) with people living with chronic pain (n = 26) and community pharmacists (n = 19), conducted between July 2020 and February 2021 in the province of Quebec, Canada. The semistructured discussion guides covered participants' definitions of adverse effects and decision‐making regarding their prevention and management. Discussions were audio‐recorded, transcribed verbatim and analysed using grounded theory.

Results

Both people with chronic pain and pharmacists provided varying definitions of analgesic adverse effects depending on patients' social and clinical characteristics. Present quality of life and serious long‐term risks related to treatment were described as key dimensions influencing adverse effect appraisal. Dilemmas and discrepancies occurred between patients and pharmacists when choosing to prioritize pain relief or adverse effect prevention. Some patients lacked information about their medications and wanted to be more involved in decisions, while many pharmacists were concerned by patients' self‐management of adverse effects. Preventing opioid‐related overdoses often led pharmacists to policing practices. Despite most pharmacists wishing they could have a key role in the management of pain and adverse effects face organizational and financial barriers.

Conclusion

Defining, preventing and managing adverse effects in the treatment of chronic pain requires a person‐centred approach and shared decision‐making. Clinical training improvements and healthcare organization changes are needed to support pharmacists in providing patients with community‐based follow‐up and reliable information about the adverse effects of chronic pain treatments.

Patient or Public Contribution

A person with lived experience of chronic pain was involved as a coinvestigator in the study. He contributed to shaping the study design and objectives, including major methodological decisions such as the choice of pharmacists as the most appropriate professionals to investigate. In addition, 26 individuals with chronic pain shared their experiences extensively during the FGs.

Development of an electronic tool (e-AdPharm) to address unmet needs and barriers of community pharmacists to provide medication adherence support to patients

BACKGROUND

Community pharmacists are best placed to improve medication adherence because they frequently interact with patients and have been trained to manage medication-related problems. Therefore, it is essential to equip pharmacists adequately to detect non-adherent patients quickly and intervene to improve medication adherence.

OBJECTIVE

To design e-AdPharm, a tool that addresses unmet needs and barriers of community pharmacists to provide medication adherence support to patients with chronic diseases.

METHODS

A qualitative study using 4 focus group discussions with community pharmacists was conducted with a semi-structured interview guide and discussions lasting for 1-2 h. The discussions covered the barriers and needs of pharmacists related to medication adherence support provided to patients, their expectations of an electronic tool based on prescription refills to help them provide this support, and the design of the tool. Focus group data were coded and analyzed using an iterative process, with thematic and descriptive analyses.

RESULTS

Twenty-six community pharmacists participated. Lack of time and motivation from pharmacists and patients were common barriers to the provision of medication adherence support. Accordingly, community pharmacists wished to measure medication adherence quickly, provide easily interpretable data to patients on their medication use, and raise the patient's awareness of non-adherence. The pharmacists expressed their need to have an electronic tool to share medication adherence information with the treating physician. Regarding the design of e-AdPharm, the pharmacists wanted a table displaying medication adherence with a color code representing adherence level. They also stressed the importance of a structured section enabling them to continuously document the interventions made and the need for patient follow-ups.

CONCLUSIONS

e-AdPharm meet the needs and overcome the barriers of community pharmacists to provide medication adherence support to their patients. Future studies should examine the feasibility of implementing e-AdPharm in community pharmacies and test its efficacy for improving medication adherence.

Exploring the role of teams and technology in patients' medication decision making

OBJECTIVES

We know little about how electronic health records (EHRs) should be designed to help patients, pharmacists, and physicians participate in interprofessional shared decision making. We used a qualitative approach to understand better how patients make decisions with their health care team, how this information influences decision making about their medications, and finally, how this process can be improved through the use of EHRs.

DESIGN

Participants from 4 regions across Canada took part in a semistructured interview and completed a brief demographic survey. The interview transcripts were thematically analyzed by means of the multidisciplinary framework method.

SETTINGS AND PARTICIPANTS

Thirty participants, 18 years of age and older with at least one chronic illness, were recruited from across Canada. We interviewed participants in their homes, at the school of pharmacy, or another location of their choosing.

RESULTS

We identified 4 main themes: (1) complexity of patient decision making: who, where, what, when, why; (2) relationships with physicians and pharmacists: who do I trust for what?; (3) accessing health information for decision making: how much and from where?; and (4) patients' methods of managing information for health decision making. Across the themes, participants appreciated expert advice from professionals and wanted to be informed about all options, despite concerns about limited knowledge. EHRs were perceived as a potential solution to many of the barriers identified.

CONCLUSION

Patients make decisions with their health care providers as well as with family and friends. The pharmacist and physicians play different roles in helping patients in making decisions. We found that making EHRs accessible not only to health care providers but also to patients can provide a cohesive and clear context for making medication-related decisions. EHRs may facilitate clear communication, foster interprofessional understanding, and improve patient access to their health information. Future research should examine how to develop EHRs that are adaptive to user needs and desires.

Are Lipid-Lowering and Antihypertensive Medications Used as Complements to Heart-Healthy Diets? A Scoping Review

In cardiovascular disease (CVD) prevention, whether antihypertensive and lipid-lowering medications are used as complements to heart-healthy diets has not been thoroughly assessed. This scoping review aimed to 1) analyze observational studies that assessed the relationship between diet and antihypertensive/lipid-lowering medication use and 2) evaluate whether medication was used as a complement to heart-healthy dietary intakes. We searched MEDLINE, Embase, Web of Science, and CINAHL through 14 January, 2023, for studies that assessed either 1) intraindividual changes in diet associated with lipid-lowering/antihypertensive medication initiation or use or 2) interindividual differences in diet between users and nonusers of these medications. A total of 17 studies were included. Of those, 3 prospectively assessed the intraindividual changes in diet associated with medication initiation or use, but none documented potential changes in diet prior to medication initiation. The 14 other studies compared dietary intakes of medication users and nonusers, most of which also relied on an incomplete assessment of the temporal dynamics between diet and medication use as they employed cross-sectional (n = 12) or repeated cross-sectional (n = 2) designs. Data from 8 studies, including 4 of the 5 studies from Europe, suggested that medication was used as a complement to heart-healthy diets, whereas data from the 9 other studies, including the 4 conducted in the United States, provided no such evidence, indicating potential between-country differences in this relationship. Finally, no studies investigated how the dynamics between diet and medication use influenced the long-term CVD risk. This scoping review suggests that the current literature on the relationship between lipid-lowering/antihypertensive medication use and diet provides an incomplete perspective on how medication may influence diet in CVD prevention. Prospective studies assessing intraindividual changes in diet associated with medication initiation and use and how these dynamics influence the CVD risk are thus needed.

Pain Medications Used by Persons Living With Fibromyalgia: A Comparison Between the Profile of a Quebec Sample and Clinical Practice Guidelines

Background

Pharmacological management of fibromyalgia is complex. Chronic pain management is characterized by off-label prescribing and use, multimorbidity, and polypharmacy.

Aims

This study aimed to describe pain medications use and perceived risk among people living with fibromyalgia and compare this use to evidence-based recommendations.

Methods

Directive telephone interviews were conducted with 63 individuals self-reporting a diagnosis of fibromyalgia (Quebec, Canada). The questionnaire addressed specific questions about their pain and pharmacological treatments currently used for pain management (prescribed and over-the-counter). Collected data were compared to the Canadian Fibromyalgia Clinical Practice Guidelines and to evidence reports published by recognized organizations.

Results

Despite a lack of robust scientific evidence to support opioids use to manage pain in fibromyalgia, 33% of our sample reported using them. Nonsteroidal anti-inflammatory drugs were used by 54.0% of participants, although this medication is not recommended due to lack of efficacy. Tramadol, which is recommended, was used by 23.8% of participants. Among the medications strongly recommended, anticonvulsants were used by 36.5%, serotonin norepinephrine reuptake inhibitor antidepressants by 55.6%, and tricyclic antidepressants by 22.2%. Cannabinoids (17.5%) and medical cannabis (34.9%) use were also reported. For all of these medication subclasses, no differences were found between participants not reporting (n = 35) or reporting (n = 28) more than one pain diagnosis (P < 0.05). Medication subclasses considered most at risk of adverse effects by participants were the least used.

Conclusions

Results reveal discordance between evidence-based recommendations and medications use, which highlights the complexity of pharmacological treatment of fibromyalgia.

Gender Differences in Medication Adverse Effects Experienced by People Living With Chronic Pain

Objectives

Understanding gender differences in chronic pain (CP) outcome research is essential to optimal treatment delivery. This study explored the associations between gender identity, gender roles, and the number of non-life-threatening pain medication adverse effects reported as severe by people living with CP.

Methods

The analyses were conducted using the COPE Cohort, a dataset generated through a web-based recruitment of adults with CP. Participants were asked how they identified themselves (women, men, unknown, unspecified) and gender roles were measured using the Bem Sex-Role Inventory (subgroups were formed applying the median split method). Pain medication adverse effects were assessed using a standardized checklist (none/mild/moderate/severe). A zero-inflated Poisson model was used to assess gender identity, gender roles and their interaction as potential predictors of the number of pain medication adverse effects.

Results

A total of 1,343 participants reported using pain medications. Adjusting for potential confounders, both gender identity (men vs. women: ß = −0.32, p = 0.0024) and gender roles (androgynous vs. undifferentiated: ß = 0.26, p = 0.0030) were associated with the number of pain medication adverse effects reported as severe, and they interacted with each other. The stratified analysis by gender roles showed that women reported a greater number of severe adverse effects than men among those classified as masculine and androgynous.

Discussion

Although we are unable to confirm whether the associations can be explained by differences in the experience or in the reporting of effects, gender identity and gender roles should both be explored when studying pain medication adverse effects.

Regulating Information or Allowing Deception? Pharmaceutical Sales Visits in Canada, France, and the United States

Diverse legal and regulatory measures are used internationally to control the information provided during pharmaceutical sales visits. Little is known about the comparative effectiveness of these measures however. We analyzed the perceptions of regulators, pharmaceutical industry officials, health professionals, and consumer respondents concerning these approaches in Canada, France, and the United States using an empirical realist interests-based approach. Interviews focused on the aims and effectiveness of regulation, barriers and enablers to regulation and suggestions for improvement. An alignment was found in North America regulator and industry respondents' satisfaction with the status quo and their view that further intervention is unfeasible and unnecessary. Health professionals generally expressed a lack of confidence in the impact of regulations on sales visit information while consumer advocates voiced their disappointment in both regulators and health professionals for their failure to counteract the influence of pharmaceutical marketing. Regulator and industry respondents in France differed from their North American counterparts in their willingness to increase and diversify the scope of regulatory interventions. As the first international comparison of regulatory experiences in this sector, the findings highlight the universal need for more focused and inclusive discussions among groups about how to tailor regulations to achieve public health goals.

Pharmacists practising in family medicine groups: An evaluation 2 years after experiencing a virtual community of practice

Background:

In 2018, a virtual community of practice (CoP) for pharmacists working in family medicine groups (FMGs) in Quebec province was developed. The aim of this CoP—called Réseau Québécois des Pharmaciens GMF (RQP GMF)—was to foster best practices by supporting FMG pharmacists. This study assesses the processes and outcomes of this CoP 2 years after its creation.

Methods:

We performed a cross-sectional web-based study from March to May 2020. All FMG pharmacists who were registered as members of the RQP GMF (n = 326) were sent an invitation via a newsletter. The link to the questionnaire was also publicized in the CoP Facebook group. The questionnaire comprised a 38-item validated instrument assessing 8 dimensions of the CoP. A descriptive analysis was performed.

Results:

A total of 112 FMG pharmacists (34.4%) completed the questionnaire. Respondents agreed that the RQP GMF was a joint enterprise (mean score, 4.18/5), that members shared their knowledge (mean score, 3.94/5) and engaged mutually (mean score, 3.50/5) and that the RQP GMF provided support (mean score, 3.92/5) and capacity building (mean score, 4.01/5). In general, they were satisfied with the implementation process (mean score, 3.68/5) and with activities proposed (mean score, 3.79/5). A lower proportion of respondents agreed that their participation in the RQP GMF generated external impacts, which led to a smaller mean score (3.37/5) for this dimension.

Conclusion:

The RQP GMF, one of the first communities of practice for pharmacists practising in family medicine groups, attained most of the objectives initially intended by the CoP. These results will facilitate the adaptation of processes and activities to better fulfil members’ needs. Can Pharm J (Ott) 2021;154:xx-xx.

Measuring adherence to oral antidiabetic multi-drug treatment: Comparative validity of prescription claims-based adherence measures against hospitalization

BACKGROUND

The use of prescription claims data to measure adherence to diabetes treatment is very common in research. However, there is no clear evidence regarding the accuracy of the methods used to assess adherence to multi-drug treatments for the many patients using multiple antidiabetic drugs.

PURPOSE

To assess the validity of prescription claims-based adherence measures in the context of multiple oral antidiabetic drug treatment.

METHODS

A cohort of patients who began their antidiabetic drug treatment with at least two oral antidiabetic drugs (new users) was created using Quebec medico-administrative data. Four different prescription claims-based adherence measures were assessed: proportion of days covered (PDC) by at least one class of drugs, mean PDC, PDC by all classes and daily polypharmacy possession ratio (DPPR). All-cause and diabetes-related hospitalizations were the validation criteria. To assess the validity of the measures, receiver operating characteristic (ROC) curves were plotted for each measure and each criterion.

RESULTS

A total of 5982 individuals were included. The areas under the ROC curves for the PDC by at least one class of drugs, the mean PDC, the PDC by all classes of drugs and the DPPR were respectively 0.54 (95% CI: 0.52-0.56), 0.51 (0.49-0.53), 0.50 (0.48-0.52) and 0.51 (0.49-0.53) with all-cause hospitalization as criterion and 0.55 (0.53-0.57), 0.53 (0.51-0.55), 0.51 (0.49-0.53) and 0.53 (0.51-0.55) using diabetes-related hospitalization as criterion.

CONCLUSIONS

The results suggest that all measures have poor validity in predicting hospitalizations thus raising concerns about their utility in the assessment of adherence to multi-drug treatment. Future research should assess the capacity of these measures to predict other outcomes more closely related to medication adherence.

Depression and the risk of hospitalization in type 2 diabetes patients: A nested case-control study accounting for non-persistence to antidiabetic treatment

INTRODUCTION

Depression is one of the most common comorbidities of type 2 diabetes. The relationship between these two diseases seems to be bidirectional. Both conditions separately lead to significant morbidity and mortality, including hospitalization. Moreover, depression is associated with non-persistence with antidiabetic drugs.

OBJECTIVES

To measure the effect of depression on morbidity and particularly on all-cause, diabetes-related, cardiovascular-related and major cardiovascular events-related hospitalization, adjusting for non-persistence to antidiabetic drugs and other confounders.

METHODS

We performed a nested case-control study within a cohort of type 2 diabetic individuals initiating antidiabetic drugs. Using the health administrative data of the province of Quebec, Canada, we identified all-cause, diabetes-related, cardiovascular-related and major cardiovascular hospitalizations during a maximum follow-up of eight years after the initiation of antidiabetic drug treatment. A density sampling method matched all cases with up to 10 controls by age, sex, and the Elixhauser comorbidity index. The effect of depression on hospitalization was estimated using conditional logistic regressions adjusting for non-persistence to antidiabetic drug treatment and other variables.

RESULTS

We identified 41,550 all-cause hospitalized cases, of which 34,437 were related to cardiovascular (CV) diseases, 29,584 to diabetes, and 13,867 to major CV events. Depression was diagnosed in 2.51% of all-cause hospitalizations and 1.16% of matched controls. 69.11% of cases and 72.59% of controls were on metformin monotherapy. The majority (71.62% vs 75.02%, respectively) stayed on metformin monotherapy without adding or switching drugs during follow-up. Non-persistence was at similar rates (about 30%) in both groups. In the multivariable analyses, depression was associated with an increased risk for all-cause hospitalizations, with odds ratios (ORs) ranging from 2.21 (95% CI: 2.07-2.37) to 1.32 (95% CI: 1.22-1.44) according to the model adjustment (from the univariate to the fully adhjusted).

CONCLUSION

Depression increased the risk of all-cause hospitalizations among patients treated for diabetes, even after accounting for non-persistence and other potentially confounding factors. These results stress the impact of depression on diabetic patients' use of health care resources.

Monitoring and managing medication adherence in community pharmacies in Quebec, Canada

Background

Community pharmacists have direct access to prescription refill information and regularly interact with their patients. Therefore, they are in a unique position to promote optimal medication use.

Objectives

To describe how community pharmacists in Quebec, Canada, identify nonadherent patients, monitor medication use and promote optimal medication adherence.

Methods

An invitation to complete a web-based survey was published online through different platforms, including a Facebook pharmacists' group, an electronic newsletter, a pharmacy network forum and e-mail. The survey included questions on participant characteristics, methods used by pharmacists to identify nonadherent patients and monitor medication use and interventions they used to promote medication adherence.

Results

In total, 342 community pharmacists completed the survey. The participants were mainly women (71.6%), staff pharmacists (56.7%) and aged 30 to 39 years (34.2%). The most common method to identify nonadherent patients was to check gaps between prescription refills (98.8%). The most common intervention to promote adherence was patient counselling (82.5%). The most common barriers to identifying nonadherent patients were lack of time (73.1%) and lack of prescription information (65.8%), whereas the most common barriers to intervening were anticipation of a negative reaction from their patients (91.2%) and lack of time (64%).

Conclusion

Lack of time and lack of prescription information are frequent challenges encountered by community pharmacists regarding effective monitoring and management of patients with poor medication adherence. Pharmacists could benefit from electronic tools based on prescription refills that would provide quick and easily interpretable information on their patients' medication adherence.

Development of Quality Indicators to Assess Oral Anticoagulant Management in Community Pharmacies for Patients with Atrial Fibrillation

BACKGROUND

Few studies have evaluated the quality of oral anticoagulant management by community pharmacists. There is no complete set of quality indicators available for this purpose.

OBJECTIVE

To develop a set of specific quality indicators to assess oral anticoagulant management by community pharmacists for patients with atrial fibrillation (AF).

METHODS

Quality indicators were developed in 3 phases. In phase 1, potential quality indicators were generated based on clinical guidelines and a literature review. In phase 2, a modified RAND appropriateness method involving 2 rounds was implemented with 9 experts, who judged the appropriateness of quality indicators generated in phase 1 based on the extent to which they were accurate, based on evidence, relevant, representative of best practices, and measurable in community pharmacies. Phase 3 consisted of a feasibility assessment in 5 community pharmacies on 2 patients each.

RESULTS

The final set included 38 quality indicators grouped into 6 categories: documentation (n = 29), risk assessment (n = 3), clinical control (n = 1), clinical follow-up (n = 15), choice of therapy (n = 11), and interaction management (n = 8). The quality indicators referred to process of care (n = 34), clinical outcomes (n = 2), or structure of care (n = 2). There were 24 quality indicators related to vitamin K antagonists (VKAs), and 17 were related to direct oral anticoagulants (DOACs). To assess quality indicators, a questionnaire was developed for completion by community pharmacists for each patient, which included 17 questions about VKA patients and 12 questions about DOAC patients.

CONCLUSIONS

A first set of quality indicators is now available to assess the quality of oral anticoagulant management by community pharmacists for patients with AF.

French-Canadian translation of a self-report questionnaire to monitor opioid therapy for chronic pain: The Opioid Compliance Checklist (OCC-FC)

Context: Chronic noncancer pain (CNCP) is a frequent condition among Canadians. The psychosocial and economic costs of CNCP for individuals, their families, and society are substantial. Though opioid therapy is often used to manage CNCP, it is also associated with risks of misuse. The Opioid Compliance Checklist (OCC) was developed to monitor opioid misuse in patients taking opioids for CNCP. The objective of the present study was to provide a French-Canadian translation of the eight-item OCC, the OCC-FC. Methods: The eight-item OCC was translated for use in Québec using published guidelines for the translation and adaptation of self-report measures, including an expert committee and a double forward-backward translation process. A pretest of the adapted eight-item OCC was also conducted among 30 patients with CNCP. Results: A French-Canadian version of the OCC was generated. When ambiguity in the items was detected during expert committee consultation or pretest administration, modifications made were kept to a strict minimum to facilitate future comparisons across studies using the original English and translated French-Canadian version. Discussion: This study provides a culturally adapted tool that will contribute to identifying French-Canadian patients with CNCP who misuse opioids over the course of opioid therapy. This translation of the OCC has the strong potential to be useful in research and clinical settings.

Strategies to prevent long-term opioid use following trauma: a Canadian practice survey

PURPOSE

To evaluate how Canadian clinicians involved in trauma patient care and prescribing opioids perceive the use and effectiveness of strategies to prevent long-term opioid therapy following trauma. Barriers and facilitators to the implementation of these strategies were also assessed.

METHODS

We conducted a web-based cross-sectional survey. Potential participants were identified by trauma program managers and directors of the targeted departments in three Canadian provinces. We designed our questionnaire using standard health survey research methods. The questionnaire was administered between April 2021 and November 2021.

RESULTS

Our response rate was 47% (350/744), and 52% (181/350) of participants completed the entire survey. Most respondents (71%, 129/181) worked in teaching hospitals. Multimodal analgesia (93%, 240/257), nonsteroidal anti-inflammatory agents (77%, 198/257), and physical stimulation (75%, 193/257) were the strategies perceived to be the most frequently used. Several preventive strategies were perceived to be very effective by over 80% of respondents. Of these, some that were reported as not being frequently used were perceived to be among the most effective ones, including guidelines or protocols, assessing risk factors for opioid misuse, physical health follow-up by a professional, training for clinicians, patient education, and prescription monitoring systems. Staff shortages, time constraints, and organizational practices were identified as the main barriers to the implementation of the highest ranked preventive strategies.

CONCLUSIONS

Several strategies to prevent long-term opioid therapy following trauma are perceived as being effective by those prescribing opioids in this population. Some of these strategies appear to be commonly used in everyday practice and others less so. Future research should focus on which preventive strategies should be given higher priority for implementation before assessing their effectiveness.

Experience and perspectives of users and non-users of the Ask your pharmacist teleconsultation platform

Background

There is a growing trend concerning the use of information and communication technologies (ICT) for seeking health-related information such as information on medications and side effects. However, people looking online for health information cannot always judge the credibility of the information.

Objective(s)

This study aimed to describe patients' and pharmacists' experience using an asynchronous teleconsultation platform entitled “Ask Your Pharmacist” (AYP) and gather their perspectives and those of various healthcare and social services professionals providing primary care.

Methods

We performed semi-structured individual interviews over the telephone with patients having used the platform, pharmacists providing teleconsultation services on the platform, and various professionals delivering healthcare and psychosocial services to ambulatory patients. The questions explored specific themes, such as the perceived utility and impacts of the platform. We transcribed the interviews and performed a content analysis.

Results

We interviewed eight patients, six AYP pharmacists, and 15 healthcare and social services professionals. Participants perceived that the platform was simple to use and accessible. They also perceived that AYP promoted the visibility and the value of pharmacists' services. Some constraints were also shared, notably regarding questions requiring immediate attention or about complex situations.

Conclusions

The experience and perspectives of users and non-users of the AYP platform are mostly positive, but concerns were also raised regarding patients' safety. Results suggest that AYP could be a complementary tool to offer to ambulatory patients for simple, general and non-urgent problems.
