Background: Cardiovascular diseases (CVD) represent a heavy economic burden on individuals, health services, and society. Low adherence to antihypertensive (AH) agents is acknowledged as a major ...contributor to the lack of blood pressure control, and may have a significant impact on clinical outcomes and healthcare costs. Objectives: To evaluate the impact of low adherence to AH agents on cardiovascular outcomes and hospitalization costs. Methods: A cohort of 59,647 patients with essential hypertension was reconstructed from the Régie de l'assurance maladie du Québec and Med-Echo databases. Subjects included were between 45 and 85 years of age, without any evidence for symptomatic CVD, newly treated with AH agents between 1999 and 2002 and followed-up for a 3-year period. Adherence to AH agents was categorized as ≥80% or <80%. The adjusted odds ratio (OR) for CVD events between the 2 adherence groups was estimated using a polytomous logistic analysis. A 2-part model was applied for hospitalization costs. Results: Patients with low adherence were more likely to have coronary disease (OR, 1.07; 95% confidence interval CI, 1.00–1.13), cerebrovascular disease (OR, 1.13; 95% CI, 1.03–1.25), and chronic heart failure (OR, 1.42; 95% CI, 1.27–1.58) within the 3-year follow-up period. Among hospitalized patients, low adherence to AH therapy was associated with increased costs by approximately $3574 (95% CI, $2897–$4249) per person within a 3-year period. Conclusions: Low adherence to AH agents is correlated with a higher risk of vascular events, hospitalization, and greater healthcare costs. An increased level of adherence to AH agents should provide a better health status for individuals and a net economic gain.
An increased interest is observed in broadening community pharmacists' role in public health. To date, little information has been gathered in Canada on community pharmacists' perceptions of their ...role in health promotion and prevention; however, such data are essential to the development of public-health programs in community pharmacy. A cross-sectional study was therefore conducted to explore the perceptions of community pharmacists in urban and semi-urban areas regarding their ideal and actual levels of involvement in providing health-promotion and prevention services and the barriers to such involvement.
Using a five-step modified Dillman's tailored design method, a questionnaire with 28 multiple-choice or open-ended questions (11 pages plus a cover letter) was mailed to a random sample of 1,250 pharmacists out of 1,887 community pharmacists practicing in Montreal (Quebec, Canada) and surrounding areas. It included questions on pharmacists' ideal level of involvement in providing health-promotion and preventive services; which services were actually offered in their pharmacy, the employees involved, the frequency, and duration of the services; the barriers to the provision of these services in community pharmacy; their opinion regarding the most appropriate health professionals to provide them; and the characteristics of pharmacists, pharmacies and their clientele.
In all, 571 out of 1,234 (46.3%) eligible community pharmacists completed and returned the questionnaire. Most believed they should be very involved in health promotion and prevention, particularly in smoking cessation (84.3%); screening for hypertension (81.8%), diabetes (76.0%) and dyslipidemia (56.9%); and sexual health (61.7% to 89.1%); however, fewer respondents reported actually being very involved in providing such services (5.7% lifestyle, including smoking cessation, 44.5%, 34.8%, 6.5% and 19.3%, respectively). The main barriers to the provision of these services in current practice were lack of: time (86.1%), coordination with other health care professionals (61.1%), staff or resources (57.2%), financial compensation (50.8%), and clinical tools (45.5%).
Although community pharmacists think they should play a significant role in health promotion and prevention, they recognize a wide gap between their ideal and actual levels of involvement. The efficient integration of primary-care pharmacists and pharmacies into public health cannot be envisioned without addressing important organizational barriers.
The benefits of antihypertensive (AH) drugs on the risks of major cardiovascular outcomes have been demonstrated in clinical trials. However, approximately half of hypertensive patients do not adhere ...well to their prescribed AH therapy in actual practice. The purpose of this study was to assess the impact of adherence to AH agents on the incidence of cerebrovascular disease (CD) in real-world practice.
A cohort of 83 267 hypertensive patients was reconstructed from the Régie de l'assurance maladie du Québec databases. Subjects included were between 45 and 85 years old, initially free of cardiovascular disease, and newly treated for hypertension with AH agents between 1999 and 2004. A nested case-control design was conducted to study CD occurrence. Every case was matched for age and duration of follow-up with up to 15 randomly selected control subjects. The adherence to AH drugs was measured by calculating the medication possession ratio. Conditional logistic regression models were performed to assess the association between adherence to AH agents and CD adjusting for various potential confounders.
At cohort entry, the mean patient age was 65 years, 37.3% were male, 8.6% had diabetes, and 19.5% had dyslipidemia. High adherence (>/=80%) to AH drugs significantly decreased the risk of CD by 22% (rate ratio, 0.78; 95% CI, 0.70 to 0.87) compared with lower adherence. Male gender, occurrence of cardiovascular disease during follow-up, and dyslipidemia were risk factors for CD.
High adherence to AH therapy is associated with a reduced risk of CD outside the context of clinical trials in primary prevention.
Abstract Background Evidence from meta-analyses shows that statin therapy reduces all-cause mortality and nonhemorrhagic strokes. Nonadherence to statins may reduce this protective effect. The ...association between statin adherence and incidence of cerebrovascular disease remains unexplored outside the context of clinical trials. Objective To evaluate the impact of statin adherence on the occurrence of cerebrovascular disease in a real clinical setting. Methods A cohort of 112,092 patients was reconstructed using the Régie d'assurance maladie du Québec and Med-Echo databases. The Régie d'assurance maladie du Québec database contains information from 3 types of health-related data, such as demographic information, medical data, and the prescription claims file. The Med-Echo database contains data on acute care hospitalizations on all Quebec residents. All patients without cardiovascular disease aged 45-85 years who were newly treated with statins between 1999 and 2004 were eligible. A nested case-control design was used to study the occurrence of cerebrovascular disease. Adherence level was reported as a medication possession ratio. Conditional logistic regression models were used to estimate the rate ratio of cerebrovascular disease, adjusting for different covariables. Results The mean patient age was 63 years; 49% had hypertension, 21% had diabetes, and 41% were males. Nonadherence was prevalent because only 55% of the patients were exposed to ≥80% of the medication during follow-up. We did not observe any major differences, defined as more than 5%, between the groups, except for the sex, diabetes, and hypertension. High level of adherence to statins was associated with a reduction of cerebrovascular events (rate ratio: 0.74; 95% confidence interval, 0.65-0.84). Conclusions Our study suggests a relatively low level of adherence to statins, but more importantly, that adherence is associated with a risk reduction for cerebrovascular disease. Adherence to statin therapy needs to be improved, so that patients can benefit from the full protective effects of statin therapy.
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.
Primary care providers' knowledge, attitudes and beliefs (KAB) regarding chronic noncancer pain (CNCP) are a barrier to optimal management.
To evaluate and identify the determinants of the KAB of ...primary care physicians and pharmacists, and to document clinician preferences regarding the content and format of a continuing education program (CEP).
Physicians and pharmacists of 486 CNCP patients participated. Physicians completed the original version of the KnowPain-50 questionnaire. Pharmacists completed a modified version. A multivariate linear regression model was developed to identify the determinants of their KAB.
A total of 137 of 387 (35.4%) physicians and 110 of 278 (39.5%) pharmacists completed the survey. Compared with the physicians, the pharmacists surveyed included more women (64% versus 38%) and had less clinical experience (15 years versus 26 years). The mean KnowPain-50 score was 69.3% (95% CI 68.0% to 70.5%) for physicians and 63.8% (95% CI 62.5% to 65.1%) for pharmacists. Low scores were observed on all aspects of pain management: initial assessment (physicians, 68.3%; pharmacists, 65.4%); definition of treatment goals and expectations (76.1%; 61.6%); development of a treatment plan (66.4%; 59.0%); and reassessment and management of longitudinal care (64.3%; 53.1%). Ten hours of reported CEP sessions increased the KAB score by 0.3 points. All clinicians considered a CEP for CNCP to be essential. Physicians preferred an interactive format, while pharmacists had no clear preferences.
A CEP to improve primary care providers' knowledge and competency in managing CNCP, and to reduce false beliefs and inappropriate attitudes regarding CNCP is relevant and perceived as necessary by clinicians.
Abstract Objective Statins have been shown to reduce the risk of major cardiovascular disease. We recognize that there is a major gap between the use of statins in actual practice and treatment ...guidelines for dyslipidemia. Low adherence to statins may have a significant impact on clinical issues and health-care costs. The objective is to evaluate the impact of low adherence to statins on clinical issues and direct health-care costs. Methods A cohort of 55,134 patients newly treated with statins was reconstructed from the Régie de l'Assurance Maladie du Québec and Med-Echo databases. Subjects included were aged between 45 and 85, initially free of cardiovascular disease, newly treated with statins between 1999 and 2002, and followed-up for a minimum of 3 years. Adherence to statins was measured in terms of the proportion of days' supply of medication dispensed over a defined period, and categorized as ≥80% or <80%. The adjusted odds ratio (OR) of cardiovascular events between the two adherence groups was estimated using a polytomous logistic analysis. The mean costs of direct health-care services were evaluated. A two-part model was applied for hospitalization costs. Results The mean high adherence level to statins was around to 96% during follow-up; and this value was at 42% for the low adherence level. The patients with low adherence to statins were more likely to have coronary artery disease (OR 1.07; 95% confidence interval CI, 1.01–1.13), cerebrovascular disease (OR 1.13; 95% CI 1.03–1.25), and chronic heart failure within 3-year period of follow-up (OR 1.13; 95% CI 1.01–1.26). Low adherence to statins was also associated with an increased risk of hospitalization by 4% (OR 1.04; 95% CI 1.01–1.09). Among patients who were hospitalized, low adherence to statins was significantly associated with increase of hospitalization costs by approximately $1060/patient for a 3-year period. Conclusion Low adherence to statins was correlated with a higher risk of cardiovascular disease, hospitalization rate, and hospitalization costs. An increased level of adherence to statins agents should provide a better health status for individuals and a net economic gain.
Hypertension is a leading mortality risk factor yet inadequately controlled in most affected subjects. Effective programs to address this problem are lacking. We hypothesized that an information ...technology-supported management program could help improve blood pressure (BP) control.
This randomized controlled trial included 223 primary care hypertensive subjects with mean 24-hour BP >130/80 and daytime BP >135/85 mm Hg measured with ambulatory monitoring (ABPM). Intervention subjects received a BP monitor and access to an information technology-supported adherence and BP monitoring system providing nurses, pharmacists, and physicians with monthly reports. Control subjects received usual care. The mean (+/-SD) follow-up was 348 (+/-78) and 349 (+/-84) days in the intervention and control group, respectively. The primary end point of the change in the mean 24-hour ambulatory BP was consistently greater in intervention subjects for both systolic (-11.9 versus -7.1 mm Hg; P<0.001) and diastolic BP (-6.6 versus -4.5 mm Hg; P=0.007). The proportion of subjects that achieved Canadian Guideline target BP (46.0% versus 28.6%) was also greater in the intervention group (P=0.006). We observed similar BP declines for ABPM and self-recorded home BP suggesting the latter could be an alternative for confirming BP control. The intervention was associated with more physician-driven antihypertensive dose adjustments or changes in agents (P=0.03), more antihypertensive classes at study end (P=0.007), and a trend toward improved adherence measured by prescription refills (P=0.07).
This multidisciplinary information technology-supported program that provided feedback to patients and healthcare providers significantly improved blood pressure levels in a primary care setting.
Background Some pharmacist-managed anticoagulation services (PMAS) provide initial follow-up to patients on oral anticoagulant, who are transferred to their physician once they are stabilized. This ...may be as effective as and less expensive than long-term PMAS follow-up. Methods Once PMAS patients were stabilized and ready for discharge, they were randomized to be transferred to their physician or stay with the PMAS. Quality of international normalized ratio (INR) control, incidence of complications, health-related quality of life, use of health care services, and direct incremental cost of PMAS follow-up were evaluated. Results One hundred thirty-eight physicians and 250 patients participated. Patients were initially followed at the PMAS for a mean of 11.3 weeks and afterwards were followed by their physician (n = 122) or by the PMAS pharmacists (n = 128) for a mean of 14.9 and 14.5 weeks, respectively. Pharmacist-managed anticoagulation services' and physician's patients were within the exact target range 77.3% and 76.7% of the time (95% CI of the difference −4.9% to 6.0%) and within the extended range 93.0% and 91.6% of the time (95% CI −2.1% to 4.7%), respectively. Pharmacist-managed anticoagulation services patients have seen their family physician less often (95% CI −3.1 to −0.1 visit per year). Number of INR tests, incidence of complications, and health-related quality of life were similar in both groups. The incremental cost of PMAS follow-up was estimated at CAN$123.80 per patient year. Conclusion Once PMAS patients are well stabilized, maintaining a PMAS follow-up or transferring them to their physician is associated with excellent INR control. However, long-term PMAS follow-up may be more expensive.
Background Explicit criteria for judging medication safety and use issues in patients with chronic kidney disease (CKD) are lacking. Study Design Quality improvement report. Setting & Participants ...Nephrologists (n = 4), primary care physicians (n = 2), hospital pharmacists with expertise in nephrology (n = 4), and community pharmacists (n = 2). The PAIR (Pharmacotherapy Assessment in Chronic Renal Disease) criteria were applied retrospectively to 90 patients with CKD in a randomized study. Quality Improvement Plan Development of an explicit set of criteria to enable rapid and systematic detection of drug-related problems (DRPs). Using a RAND method, experts judged the clinical significance of DRPs and the appropriateness of a community pharmacist intervention. The PAIR criteria include 50 DRPs grouped into 6 categories. Outcomes DRPs detected using the PAIR criteria compared with implicit clinical judgment by nephrology pharmacists. Measurements Prevalence of DRPs and reliability, validity, and responsiveness of the PAIR criteria. Results A mean of 2.5 DRPs/patient (95% CI, 2.0-3.1) was identified based on the PAIR criteria compared with 3.9 DRPs/patient (95% CI, 3.4-4.5) based on clinical judgment of nephrology pharmacists. Inter-rater reliability coefficients (κ) by PAIR category varied from 0.80-1.00, with an intraclass correlation coefficient (ICC) of 0.93 (95% CI, 0.89-0.95) for total DRPs per patient. Test-retest reliability coefficients by category varied from 0.74-1.00, with an ICC of 0.91 (95% CI, 0.82-0.96) for total DRPs per patient. During the study, the mean number of DRPs per patient did not change significantly when assessed using the PAIR criteria and clinical judgment. Limitation The prevalence of PAIR DRPs may be underestimated due to the retrospective nature of the validation. Conclusion The prevalence of DRPs requiring the intervention of community pharmacists is high in patients with CKD. The PAIR criteria are reliable, but their responsiveness remains to be shown.
