Awareness Among Primary Care Physicians in Canada of Guideline Recommendations for Lowering LDL-Cholesterol in High-Risk Patients.

Background: Cardiovascular (CV) risk management for high-risk patients is often provided by primary care physicians (PCPs). We surveyed Canadian PCPs regarding their awareness and implementation of the 2021 Canadian Cardiovascular Society (CCS) lipid guideline recommendations for patients following an acute coronary syndrome (ACS) and those with diabetes but without CV disease. Methods: A committee of PCPs and specialists with lipid expertise, including some 2021 CCS lipid guideline coauthors, designed a survey to probe PCP awareness and practice patterns regarding CV risk management. From a national database, a total of 250 PCPs completed the survey between January and April 2022. Results: Almost all PCPs (97.2%) concurred that a post-ACS patient should be seen by their PCP within 4 weeks of hospital discharge (81.2% said within 2 weeks). Almost half (44.4%) responded that discharge summaries provided inadequate information, and 41.6% felt that lipid management post-ACS was the responsibility primarily of specialists. A total of 58.4% articulated that they face challenges when seeing a post-ACS patient, related to inadequate discharge information, complexities of polypharmacy and duration of therapies, and managing statin intolerance. A total of 63.2% and 43.6% correctly identified low-density lipoprotein cholesterol (LDL-C) intensification thresholds of 1.8 mmol/L in post-ACS patients, and 2.0 mmol/L in diabetes patients, respectively, and 81.2% incorrectly thought that proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors were indicated for patients with diabetes but without CV disease. Conclusions: One year following publication of the 2021 CCS lipid guidelines, our survey reveals knowledge gaps among responding PCPs regarding intensification thresholds and treatment options for patients post-ACS, or those with diabetes. Innovative and effective knowledge-translation programs to address these gaps are desirable.

Contexte: La prise en charge du risque cardiovasculaire (CV) chez les patients à risque élevé est souvent réalisée par les médecins en soins primaires (MSP). Nous avons donc sondé les MSP canadiens quant à leur connaissance des lignes directrices 2021 de la Société cardiovasculaire du Canada (SCC) sur les lipides et leur mise en œuvre auprès des patients ayant subi un syndrome coronarien aigu (SCA) et auprès des patients atteints de diabète qui ne présentent pas de maladie CV. Méthodologie: Un comité de MSP et de spécialistes ayant une expertise sur la question des lipides, y compris certains coauteurs des lignes directrices 2021 de la SCC sur les lipides, a conçu un sondage pour évaluer la connaissance des mesures de prise en charge du risque CV et les habitudes de pratique des MSP en la matière. Au total, 250 MSP provenant d'une banque de données nationale ont rempli le sondage entre janvier et avril 2022. Résultats: Presque tous les MSP (97,2 %) étaient d'accord pour dire que les patients ayant subi un SCA devraient avoir une consultation avec leur MSP dans les quatre semaines suivant leur congé de l'hôpital (81,2 % ont dit deux semaines). Près de la moitié des répondants (44,4 %) ont indiqué que le sommaire d'hospitalisation fournit une information inadéquate, et 41,6 % estimaient que la gestion des lipides après un SCA relevait des spécialistes. Au total, 58,4 % des répondants ont mentionné rencontrer des difficultés lors de la consultation avec un patient après une SCA, surtout quant à l'information inadéquate contenue dans le sommaire d'hospitalisation, aux complexités de la polypharmacie, à la durée des traitements et à l'intolérance aux statines. De plus, 63,2 % et 43,6 % des répondants ont correctement indiqué les seuils d'intensification du traitement pour le cholestérol à lipoprotéines de basse densité (LDL), soit 1,8 mmol/l chez les patients après un SCA et 2,0 mmol/l chez les patients diabétiques, respectivement. Par ailleurs, 81,2 % des répondants croyaient à tort que les inhibiteurs de la proprotéine convertase subtilisine/kexine de type 9 (PCSK9) étaient indiqués pour les patients diabétiques ne présentant pas de maladie CV. Conclusions: Un an après la publication des lignes directrices 2021 de la SCC sur les lipides, notre sondage montre des lacunes dans les connaissances des MSP quant aux seuils d'intensification du traitement et aux options de traitement pour les patients ayant subi un SCA ou atteints de diabète. Des programmes novateurs et efficaces de transmission du savoir sont souhaitables pour combler ces lacunes.

Clinicians Are Not Able to Infer Parental Intentions to Vaccinate Infants with a Seasonal Influenza Vaccine, and Perhaps They Should Not Try: Findings from the Pediatric Influenza Vaccination Optimization Trial (PIVOT)-IV.

This prospective cohort survey evaluated the concordance of clinicians' perceptions of parental intentions and parents' actual intentions to vaccinate their infants against influenza. During a routine healthy baby visit, clinicians provided parents with information about influenza, children's vulnerability to influenza, and nonadjuvanted and adjuvanted trivalent influenza vaccines (TIV and aTIV, respectively). Before and after the clinician−parent interaction, parents were surveyed about their attitudes, their perceptions of support from significant others, and the intention to vaccinate their infant with aTIV. Clinicians were asked about their perception of parents' intentions to choose aTIV for their children. These assessments included 24 clinicians at 15 community practices and nine public health clinics, and 207 parents. The correlation coefficients of the clinicians' assessment of parents' intention to vaccinate were 0.483 (p < 0.001) if the vaccine was presented as free of cost, 0.266 (p < 0.001) if the cost was $25, and 0.146 (p = 0.036) if the cost was $50, accounting for 23%, 7%, and 2% of the variance in parental intentions, respectively. The clinicians were poor at predicting parental intentions to immunize, particularly when cost was involved. Information on vaccine options and influenza infection should be provided for every eligible patient to allow parents to determine if the vaccine is appropriate for their child.

Parental Attitudes and Perceptions of Support after Brief Clinician Intervention Predict Intentions to Accept the Adjuvanted Seasonal Influenza Vaccination: Findings from the Pediatric Influenza Vaccination Optimization Trial (PIVOT)-I.

Adjuvanted trivalent influenza vaccine (aTIV) provides enhanced protection against seasonal influenza in children compared with nonadjuvanted trivalent influenza vaccine (TIV). This prospective cohort study assessed parental attitudes, beliefs, and intentions to vaccinate their infants aged 6-23 months with aTIV. Parents were surveyed before and after routine healthy baby visits, and post clinician interaction results were analyzed using multivariable logistic regression. Physicians at 15 community practice clinics and nurses at 3 public health clinics participated; 207 parents were surveyed. After clinician consultation, most parents considered immunization with aTIV to be safe (72.9%), effective (69.6%), and important (69.0%); most perceived support for vaccination from significant others (62.8%) and clinicians (81.6%); and 66.6% intended to vaccinate their infant with aTIV. Parental attitudes toward vaccinating their infant with aTIV were strongly correlated with perceptions of vaccine safety, efficacy, and importance, and these represented the strongest influence on intentions to vaccinate (odds ratio (OR) 79.25; 95% confidence interval (CI) 6.05-1037.50). Parental intentions were further influenced by perceived strength of clinician recommendation (OR 4.55, 95% CI 1.38-15.06) and social support for vaccination (OR 3.46, 95% CI 0.50-24.13). These findings may inform clinician approaches to parental education to ensure optimal seasonal pediatric influenza vaccination.

Understanding the Impact of Approved but Unfunded Vaccine Status on Parental Acceptance of an Adjuvanted Seasonal Influenza Vaccine for Infants: Results from the Pediatric Influenza Vaccination Optimization Trial (PIVOT)-III.

The adjuvanted trivalent influenza vaccine (aTIV) provides enhanced protection against influenza for infants but is not publicly funded (NPF). The objective of this prospective cohort study of parents with children 6 through 23 months of age was to understand how NPF status influences parental perceptions of approved but unfunded vaccines and their intentions to vaccinate. At healthy baby visits, clinicians provided parents with information about influenza and vaccination. Before and after these interactions, a research nurse assessed parents' intentions to vaccinate their children and their beliefs about the safety, efficacy, and necessity of vaccinating their children with aTIV in both publicly funded (PF) and NPF settings. Overall, 15 community practice clinics (n = 15 physicians) and nine public health clinics (n = 9 nurses) recruited 207 parents. The percentage of parents intending to immunize their children with aTIV decreased from 72% (vaccine PF, free of charge), to 42% (NPF, $25 per dose), to 27% (NPF, $50 per dose). Funding status strongly influenced whether parents perceived immunization with aTIV to be necessary, safe, and effective. Information on influenza and influenza vaccines should be provided to parents routinely to allow for well-informed decisions on the suitability of specific influenza vaccines for their child.

Immunization for midlife women.

OBJECTIVE: Menopause occurs at a critical juncture in life when preventative health care can have a major impact. However, recommendations for immunizations are often neglected, leading to unnecessary morbidity and mortality in aging women. The aim of this review is to highlight the importance of immunization checkpoints at menopause to optimize the quality of care and health maintenance in older women and to provide an overview of the impact of immunizations on women's health. METHODS: This is an opinion article based on the current US and Canadian guidelines. A review of various guidelines from the Centers for Disease Control and Prevention and National Advisory Committee on Immunizations were conducted for each vaccine. RESULTS AND CONCLUSIONS: Disease prevention benefits are well established for several diseases, such as hepatitis A, hepatitis B, tetanus, human papillomavirus, streptococcus pneumonia, shingles, and COVID-19. During clinical encounters, a needs assessment regarding vaccinations should be conducted. However, barriers to adult vaccination including lack of patient and provider knowledge about the need for vaccination, lack of priority for preventive services, and concerns regarding costs, insurance coverage, and reimbursement all contribute to the adult immunization gap. Given the importance of immunization and the need to decrease vaccine-preventable diseases, it is the obligation of healthcare practitioners to recommend vaccines and provide education on vaccination guidelines and associated risks. As women often seek medical attention at menopause because of changes in their physiology that require attention, it is the ideal time to discuss the importance of immunization.

Continuing Medical Education Improves Physician Communication Skills and Increases Likelihood of Pediatric Vaccination: Findings from the Pediatric Influenza Vaccination Optimization Trial (PIVOT)-II.

This study evaluated the impact of a continuing medical education (CME) program that emphasized actionable information, motivation to act, and skills to strengthen physician recommendations for seasonal influenza vaccination in children 6 through 23 months of age for whom influenza immunization rates are suboptimal. Physicians were randomly assigned to an accredited CME program or to no CME. Participants completed pre- and post-study questionnaires. Influenza immunization rates were compared between groups. A total of 33 physicians in the CME group and 35 in the control group documented 292 and 322 healthy baby visits, respectively. Significantly more parents immunized their children against influenza after interacting with CME-trained physicians than those with no CME training (52.9% vs. 40.7%; p = 0.007). The odds ratio for vaccination after visits with CME-trained physicians was 1.52 (95% confidence interval 1.09 to 2.12; p = 0.014), which was unaffected by the socioeconomic status of parents. Parents who discussed influenza vaccination with CME-trained physicians were 20% more likely to choose an approved but publicly unfunded adjuvanted pediatric influenza vaccine. The percentages of physicians reporting the highest levels of knowledge, ability, and confidence doubled or tripled after the CME intervention. Significantly more parents immunized very young children after interacting with physicians who had undergone CME training.

Select immunizations for adult women.

National standards for immunizations are set by the Advisory Committee on Immunization Practices in the United States and the National Advisory Committee on Immunizations in Canada. In Mexico, the National Immunization Technical Advisory Group sets standards for infants and adolescents but not for adults. In this Practice Pearl, guidelines for some adult immunizations in women and the recent and potential upcoming changes in vaccines are reviewed.

Fragility fracture identifies patients at imminent risk for subsequent fracture: real-world retrospective database study in Ontario, Canada.

BACKGROUND: The secondary fracture prevention gap in the osteoporosis field has been previously described as a 'crisis'. Closing this gap is increasingly important in the context of accumulating evidence showing that an incident fragility fracture is associated with an increased risk of subsequent fracture within 1-2 years, known as imminent fracture risk. The objective of this study was to use health services data to characterize the time between index fragility fractures occurring at different osteoporotic sites and subsequent fractures. METHODS: This retrospective observational study used de-identified health services data from the publicly funded healthcare system in Ontario, the largest province of Canada. Patients aged > 65 with an index fragility fracture occurring between 2011 and 2015 were identified from the ICES Data Repository using International Classification of Diseases (ICD)-10 codes. We examined median time to subsequent fragility fractures for osteoporotic fracture sites until the end of follow-up (2017). BMD assessment and use of osteoporosis therapies following index fracture were also characterized. RESULTS: Among 115,776 patients with an index fragility fracture, 17.8% incurred a second fragility fracture. Median time between index and second fracture occurring at any site was 555 days (interquartile range: 236-955). For each index fracture site examined, median time from index to second fracture was < 2 years. The proportion of patients with BMD assessment was 10.3% ≤1 year prior to and 16.4% ≤1 year post index fracture. The proportion of patients receiving osteoporosis therapy was 29.8% ≤1 year prior, 34.6% ≤1 year post, and 25.9% > 3 years post index fracture. CONCLUSIONS: This cohort of Canadian patients aged > 65 years who experienced a fragility fracture at any site are at imminent risk of experiencing subsequent fracture within the next 2 years and should be proactively assessed and treated.

Mortality in older adults following a fragility fracture: real-world retrospective matched-cohort study in Ontario.

BACKGROUND: Recent studies are lacking reports on mortality after non-hip fractures in adults aged > 65. METHODS: This retrospective, matched-cohort study used de-identified health services data from the publicly funded healthcare system in Ontario, Canada, contained in the ICES Data Repository. Patients aged 66 years and older with an index fragility fracture occurring at any osteoporotic site between 2011 and 2015 were identified from acute hospital admissions, emergency and ambulatory care using International Classification of Diseases (ICD)-10 codes and data were analyzed until 2017. Thus, follow-up ranged from 2 years to 6 years. Patients were excluded if they presented with an index fracture occurring at a non-osteoporotic fracture site, their index fracture was associated with a trauma code, or they experienced a previous fracture within 5 years prior to their index fracture. This fracture cohort was matched 1:1 to controls within a non-fracture cohort by date, sex, age, geography and comorbidities. All-cause mortality risk was assessed. RESULTS: The survival probability for up to 6 years post-fracture was significantly reduced for the fracture cohort vs matched non-fracture controls (p < 0.0001; n = 101,773 per cohort), with the sharpest decline occurring within the first-year post-fracture. Crude relative risk of mortality (95% confidence interval) within 1-year post-fracture was 2.47 (2.38-2.56) in women and 3.22 (3.06-3.40) in men. In the fracture vs non-fracture cohort, the absolute mortality risk within one year after a fragility fracture occurring at any site was 12.5% vs 5.1% in women and 19.5% vs 6.0% in men. The absolute mortality risk within one year after a fragility fracture occurring at a non-hip vs hip site was 9.4% vs 21.5% in women and 14.4% vs 32.3% in men. CONCLUSIONS: In this real-world cohort aged > 65 years, a fragility fracture occurring at any site was associated with reduced survival for up to 6 years post-fracture. The greatest reduction in survival occurred within the first-year post-fracture, where mortality risk more than doubled and deaths were observed in 1 in 11 women and 1 in 7 men following a non-hip fracture and in 1 in 5 women and 1 in 3 men following a hip fracture.

Vaccine strategies for prevention of community-acquired pneumonia in Canada: Who would benefit most from pneumococcal immunization?

OBJECTIVE: To describe the burden of pneumococcal disease and associated risk factors in the Canadian adult population, delineate available pneumococcal vaccines and associated efficacy and effectiveness data, and review current pneumococcal vaccine recommendations and community-acquired pneumonia (CAP) prevention strategies in Canada. QUALITY OF EVIDENCE: Pneumococcal vaccination guidelines from the Canadian National Advisory Committee on Immunization in 2013 and 2016 constitute level III evidence for CAP prevention in the Canadian adult population. MAIN MESSAGE: It is recommended that immunosuppressed adults of all ages receive the 13-valent pneumococcal conjugate vaccine (PCV13) (grades A and B recommendations). In 2016, the National Advisory Committee on Immunization also recommended that all adults aged 65 years and older receive PCV13 (grade A recommendation) on an individual basis, followed by the 23-valent pneumococcal polysaccharide vaccine (grade B recommendation). This update is based on a large clinical study that demonstrated PCV13 efficacy against vaccine-type CAP in this population. CONCLUSION: Physicians should focus on improving pneumococcal vaccination rates among adults, which remain low. Vaccination with PCV13 should also be considered for adults with chronic conditions, whose baseline risk is often higher than that for healthy individuals aged 65 years and older.

The International Society for the Study of Women's Sexual Health Process of Care for the Identification of Sexual Concerns and Problems in Women.

Sexual problems are common in women of all ages. Despite their frequency and impact, female sexual dysfunctions (FSDs) are often unrecognized and untreated in clinical settings. In response, the International Society for the Study of Women's Sexual Health convened a multidisciplinary, international expert panel to develop a process of care (POC) that outlines recommendations for identification of sexual problems in women. This POC describes core and advanced competencies in FSD for clinicians who are not sexual medicine specialists and serve as caregivers of women and, therefore, is useful for clinicians with any level of competence in sexual medicine. The POC begins with the expectation of universal screening for sexual concerns, proceeds with a 4-step model (eliciting the story, naming/reframing attention to the problem, empathic witnessing of the patient's distress and the problem's impact, and referral or assessment and treatment) that accommodates all levels of engagement, and delineates a process for referral when patients' needs exceed clinician expertise. Distressing problems related to desire, arousal, and orgasm affect 12% of women across the lifespan. Low desire is the most common sexual problem, but sexual pain and other less common disorders of arousal and orgasm are also seen in clinical practice. Screening is best initiated by a ubiquity statement that assures the patient that sexual concerns are common and can be revealed. Patient-centered communication skills facilitate and optimize the discussion. The goal of the POC is to provide guidance to clinicians regarding screening, education, management, and referral for women with sexual problems.

Specialist-Led Diabetes Registries and Prevalence of Poor Glycemic Control in Type 2 Diabetes: The Diabetes Registry Outcomes Project for A1C Reduction (DROP A1C).

OBJECTIVE: To highlight the utility of a large patient registry to identify functionally refractory patients (persistent HbA1c ≥75 mmol/mol [9.0%]) with type 2 diabetes, identify their barriers to glycemic control, and implement barrier-specific care path strategies to improve glycemic control. RESEARCH DESIGN AND METHODS: A working group developed a structured tool to optimize the collection of information on barriers to glycemic control and designed structured care paths to address each barrier. Participants were identified from a large Canadian registry and were assigned to a certified diabetes educator (CDE) as their case manager for a 12-month period to coordinate assessment of their barriers and to implement appropriate care path strategies. The primary outcome measure was the mean change in HbA1c from baseline at 12 months. RESULTS: Overall, 3,662 refractory patients were initially identified of whom 1,379 were eligible for inclusion and 155 enrolled. The most common barrier categories participants identified were psychological/support (93%), socioeconomic (87%), and accessibility (82%), with high concordance (75-94%) between participant and CDE. No specific barriers were predictive of hyperglycemia. After implementation of barrier-specific care paths, the mean reduction in HbA1c at 12 months was 17 mmol/mol (1.5%; P < 0.01 vs. baseline) versus only 5 mmol/mol (0.5%) in the source cohort (n = 966) who continued with standard care. The incidence of severe hypoglycemia did not change significantly during the study. CONCLUSIONS: In registry-identified hyperglycemic patients with type 2 diabetes, the use of barrier-specific care paths significantly improved glycemic control in otherwise refractory patients with persistently elevated HbA1c. Further studies using this strategy in other practice settings are warranted.

Specialist-led diabetes registries and predictors of poor glycemic control in type 2 diabetes: Insights into the functionally refractory patient from the LMC Diabetes Registry database.

BACKGROUND: The aim of the present study was to explore features associated with glycemic control in type 2 diabetes (T2D) patients undergoing care by specialist clinics. METHODS: Literature searches identified diabetes registries whose databases recorded outcomes of specialist care. The LMC Diabetes Registry database (n = 58 280; LMC) was queried to identify patients with T2D who had been seen in a defined 14-month period. Logistic regression modeling was used to identify predictors of glycemic control in these patients. Poor glycemic control was defined as HbA1c ≥9.0% (75 mmol/mol) despite specialist care for ≥1 year. RESULTS: Few published registry-based studies have discussed glycemic control and outcomes of specialist care for T2D. Among 10 590 LMC patients with T2D, mean HbA1c was 7.6% (60 mmol/mol), with 38% of patients meeting the Canadian Diabetes Association target of ≤7.0% (53 mmol/mol). Overall, 15% showed poor glycemic control with persistent HbA1c ≥9.0% (75 mmol/mol); among insulin-treated patients (n = 3856), 28% met this criterion. Patient characteristics independently associated with poor glycemic control included early age of onset, the number of diabetes education program visits, the number of oral therapies, and insulin use. CONCLUSIONS: Type 2 diabetes patients with poor glycemic control are found disproportionately in referral specialist care clinics. These functionally refractory patients demonstrate features that may assist in predicting their potential outcome, and may represent a group with specific barriers to care. Specialist patient registries, such as the LMC Diabetes Registry, may provide critical information regarding this cohort.

A primer on the hormone-free interval for combined oral contraceptives.

BACKGROUND: The dosing, schedules, and other aspects of combined oral contraceptive (COC) design have evolved in recent years to address a variety of issues including short- and long-term safety, bleeding profiles, and contraceptive efficacy. In particular, several newer formulations have altered the length of the hormone-free interval (HFI), in order to minimize two key undesired effects that occur during this time: hormone-withdrawal-associated symptoms (HWaS) and follicular development. OBJECTIVE: This primer reviews our current understanding of the key biological processes that occur during the HFI and how this understanding has led to changes in the dosing and schedule of newer COC formulations. MAIN MESSAGE: In brief, HWaS are common, underappreciated, and a likely contributor to COC discontinuation; because of this, shortening the HFI and/or supplementing with estrogen during the progestin-free interval may provide relief from these symptoms and improve adherence. A short HFI (with or without estrogen supplementation) may also help maintain effective follicular suppression and contraceptive efficacy, even when the overall dose of estrogen throughout the cycle is low. CONCLUSIONS: Taken together, the available data about HWaS and follicular activity during the HFI support the rationale for recent COC designs that use a low estrogen dose and a short HFI. The availability of a variety of COC regimens gives physicians a range of choices when selecting the most appropriate COC for each woman's particular priorities and needs.

Clarifying Vaginal Atrophy's Impact on Sex and Relationships (CLOSER) survey: emotional and physical impact of vaginal discomfort on North American postmenopausal women and their partners.

OBJECTIVE: This study aims to determine the emotional and physical impact of vaginal atrophy on North American postmenopausal women and their male partners. METHODS: A weighted sample of 1,000 married or cohabiting North American postmenopausal women aged 55 to 65 years with vaginal discomfort and 1,000 male partners of postmenopausal women aged 55 to 65 years who experienced vaginal discomfort participated in the Clarifying Vaginal Atrophy's Impact on Sex and Relationships (CLOSER) online survey to determine the impact of vaginal discomfort and local estrogen therapy on intimacy, relationships, and women's self-esteem. RESULTS: Vaginal discomfort caused most surveyed North American women to avoid intimacy (58%), experience loss of libido (64%), and experience pain associated with sex (64%). Most surveyed North American men also believed that vaginal discomfort caused their partners to avoid intimacy (78%), experience loss of libido (52%), and find sex painful (59%). Approximately 30% of North American women and men cited vaginal discomfort as the reason they ceased having sex altogether. North American women who used local estrogen therapy to treat their vaginal discomfort reported less painful sex (56%), more satisfying sex (41%), and improved sex life (29%). Most men reported looking forward to having sex (57%) because of their partner's use of local estrogen therapy. CONCLUSIONS: Local estrogen therapy ameliorates the negative impact of vaginal atrophy on the intimate relationships of North American postmenopausal women and their male partners. Additional education and awareness efforts about the symptoms of and available treatments for vaginal atrophy may be of further benefit to North American partners.
