Adherence to Current Lipid Guidelines by Physicians in Kuwait

Evaluation of infectious diseases physicians' attitudes to dyslipidemia management in PLWH

OBJECTIVES

Dyslipidemia is a well-established risk factor for atherosclerotic cardiovascular disease (ASCVD). ASCVD prevalence among people living with HIV (PLWH) is twice that of the general population. This study aimed to evaluate the infectious diseases (ID) physicians' attitudes on dyslipidemia management in PLWH.

METHODS

This observational, cross-sectional study was conducted as online survey among ID physicians between November 2023 and February 2024. An e-mail with the survey link, title and purpose of the study was sent to physicians through the local ID societies. The survey included questions about physicians' demographic characteristics and their attitudes toward treating dyslipidemia in PLWH.

RESULTS

A total of 242 physicians responded to the survey, of whom 59.9% (n = 145) were ID specialists and 40.1% (n = 97) were ID residents. Forty-one percent (n = 100) of physicians reported that they did not follow a guideline, and 26% of physicians reported that they did not use a cardiovascular risk calculator in their clinical practice. Specialists (69%) were more likely than residents (43.3%) to follow clinical guidelines for dyslipidemia management (p < 0.001). Seventy-two percent (n = 174) of physicians doubted the need to treat dyslipidemia, and 73% (n = 177) of physicians were affected by the patient skepticism. Workload and lack of time were identified by 68.6% of physicians as barriers to implementing dyslipidemia guideline recommendations.

CONCLUSION

A considerable number of Turkish ID physicians did not prefer using clinical guidelines for dyslipidemia and ASCVD risk calculators. Statin prescribing of physicians was influenced by workload, lack of time, patient skepticism, and lack of knowledge. Training ID physicians in primary prevention of ASCVD and management of dyslipidemia in PLWH is paramount.

Physicians' perceptions and beliefs on the current dyslipidemia management practices within Saudi Arabia

Background

Limited reports addressing physicians' understanding of the various low-density lipoprotein cholesterol (LDL-C) targets/statin intensity required for treating the various dyslipidemia patient populations in Saudi Arabia are available. Therefore, the current study assessed the perceptions and beliefs of practicing clinicians in Saudi Arabia regarding the current practice for management of dyslipidemia and potential perceived barriers to adherence to lipid guidelines encountered in their regular clinical practice. Knowledge of different clinical practices and beliefs could have a positive impact on improving the quality of future care provided by physicians.

Methods

A survey questionnaire was designed to assess physicians' familiarity, usage, and adherence to seven different international guidelines and used to evaluate the management of dyslipidemia, practice of patient treatment, and perceived obstacles to adhering to lipid guidelines related to specific patients, doctors, and practice issues.

Results

A total of 467 physicians were recruited for the study: (1) 57.2% were primary care physicians (PCPs) and (2) 42.8% were specialists. About 90.8% of them followed lipid guidelines of which the most common set were based on those by the American College of Cardiology/American Heart Association. The most utilized risk assessment tool was the atherosclerotic cardiovascular disease (ASCVD) risk calculator. About 60% of the physicians set an LDL-C target for their patients based on a combination of patients' risk factors and lipid profiles. In all, 42.1% of the physicians chose not to change existing therapy among patients with dyslipidemia to attain a non-high-density lipoprotein goal with controlled LDL-C level. Atorvastatin accounted for the greatest percentage of primary and secondary prevention choices (71.9% and 69.6%, respectively). Rosuvastatin was mostly preferred by physicians for patients with familial hypercholesterolemia. About two-thirds of the physicians (77.9%) prescribed statins to diabetic patients aged 40-75 years. Statin intolerance was encountered by 62.9% of the physicians in ≤ 10% of patients by 62.9%. Therapeutic strategies included switching to an alternative statin (40.1%) followed by reducing the statin dose (35.3%). Ezetimibe was prescribed by most physicians (77.9%) as an add-on to statin if the LDL-C target was not achieved. Fibrate was most preferred by physicians (62.7%) for hypertriglyceremia treatment followed by statins (28.7% of the physicians). Sixty-six percent reported not using proprotein convertase subtilisin/kexin type 9 serine protease inhibitors in their clinical practice due to unavailability at their institute (51.8%), high costs (26.3%), and/or lack of knowledge (20.6%). Perceived barriers to guideline adherence identified by physicians were lack of familiarity and knowledge of the guidelines, patient non-adherence, medication costs, and lack of timely follow-up appointments and educational tools. Multiple similarities and differences were observed after comparisons were made between specialists and PCPs in terms of guideline preference, clinical practice, and perceived barriers.

Conclusion

Different perceptions and attitudes among physicians in Saudi Arabia were found due to variable recommendations by international lipid guidelines. Perceived barriers that included the patient, physician, and practice were identified by physicians at multiple levels. Multiple challenges and different action gaps were observed when comparing specialists to PCPs. It is recommended that standardized practices be followed by clinicians in Saudi Arabia, and actions to address the outlined barriers are essential for optimizing health outcomes and ASCVD prevention.

Older age, kidney concordant diseases and the dilemma of adherence to guidelines: A narrative review

Evidence-based medicine is pivotal to contemporary clinical practice, and the excellence of a healthcare institution is measured by the adherence of its clinical staff to the clinical practice guidelines (CPGs) among other standards and policies. Following the recommendations of CPGs in older adults poses different challenges to prescribers. In this narrative review we explore research studies that assessed clinicians' adherence to CPGs when prescribing to older adults with chronic kidney disease and its concordant disorders, and to discuss the potential barriers and facilitators to better adherence to CPGs. Our review of the literature found that the adherence level to CPGs differed according to country, disease condition and healthcare setting. Clinicians' attitudes toward older adults and the CPGs, the unfamiliarity with the CPGs, and the lack of time, were commonly cited barriers. Interventions suggested to improve adherence to CPGs include direct mentoring, educational activities, and the integration of CPGs recommendations within hospital protocols and policies.

The approach of Iranian clinical pharmacists in the treatment of dyslipidemia based on international guidelines

Introduction: Optimal treatment of dyslipidemia is a top priority in the prevention of cardiovascular diseases. For this purpose, clinicians in Iran usually refer to four current international guidelines. The aim of this study was to assess the approach of Iranian clinical pharmacists in the treatment of dyslipidemia based on international guidelines. Methods: A structured questionnaire was prepared. Questions (n=24) included the demographics (n=7), dyslipidemia references (n=3), dyslipidemia general knowledge of respondents (n=10), and questions (n=4) designed based on the difference among the latest version of guidelines participants stated they use in their practice. After validity conformation, the questionnaire was distributed to 120 clinical pharmacists, electronically from May to August 2021. Results: Response rate was 77.5% (n=93). The majority of participants (80.6%, n=75) claimed to have used the 2018 ACC/AHA guideline. The Median (interquartile range [IQR]) score of the general knowledge questions was 5.0 (2.0) out of 10. The Median (IQR) score of questions designed based on the difference among guidelines was calculated 3(1) out of 4. There was no significant (P=0.25) difference in score among participants according to their guideline selection. Moreover, the gender and length of experience as a clinical pharmacist had no significant (P>0.05) effect on the score of participants. Conclusion: In this study, Iranian clinical pharmacists answered half of the dyslipidemia general knowledge questions correctly. Also, Participants were up-to-date on 75% of the questions designed based on the latest version of the guideline they had been using in their practice.

Physicians and pharmacists' clinical knowledge of statin therapy and monitoring parameters, and the barriers to guideline implementation in clinical practice

BACKGROUND

Millions of individuals worldwide use statins, and their significant impact on cardiovascular disease (CVD) has been well-established. However, a lack of knowledge about the up-to-date guideline recommendations regarding statin therapy is a common barrier to implementation in clinical practice. Therefore, the present study aimed to assess the current clinical knowledge about statin therapy and its monitoring parameters. Also, we evaluated the barriers to cholesterol management guideline implementation in Yemen.

METHODS

This observational cross-sectional study was conducted over four months, from June/2021 to September/2021, in Sana'a, Yemen. A validated questionnaire was distributed face-to-face to 650 participants (350 physicians and 300 pharmacists). Physicians and pharmacists from governmental and private hospitals and those working in private clinics or community pharmacies were included in the study.

RESULTS

A total of 496 participants filled out the survey, with 22 being excluded due to incomplete data. So, the study has an overall response rate of 72.9% (474). The majority of pharmacists (81.8%) and physicians (78.7%) could not identify the patient group that needed ASCVD risk assessment before statin therapy initiation. Although a significant proportion of respondents knew of the fact that high-intensity statins are recommended for patients with ASCVD (65.4%) and primary hypercholesterolemia (58.4%), the majority of physicians and pharmacists could not identify the high (61.6% and 66.7.3%, respectively) and moderate statin-intensity doses (72.2% and 68.6%, respectively). Only 21.9% of all respondents knew that atorvastatin and rosuvastatin can be administered at any time of the day. Similarly, a low overall rate of respondents (19.6%) knew that atorvastatin does not need dose adjustment in chronic kidney diseases, with a statistically significant difference in knowledge between physicians and pharmacists (12.5% vs. 25.6%, p <0.001, respectively). Notably, only 39.2% of participants were aware that statins are not safe to use during breastfeeding. Around half of respondents (52.3%) correctly identify the duration (4 to 12 weeks) at which LD-C measuring is recommended after therapy initiation or dose change. The lowest knowledge scores for respondents were related to statin-drug interactions. Age, experience, degree, and previous guideline exposure were all significantly associated with the knowledge scores (p <0.05). The four most perceived barriers to implementing cholesterol management guidelines were no audit on adherence to the guidelines in the workplace (73.4%), insufficient resources to adequately implement and follow up on the guideline's recommendations (73.6%), patient's financial status (75.7%), and lack of familiarity about the guideline's latest recommendations (63.3%).

CONCLUSION

Physicians and pharmacists had suboptimal clinical knowledge regarding statin therapy, dose intensities, drug-drug interaction, contraindications, and monitoring parameters. Therefore, physicians' and pharmacists' educational interventions regarding the up-to-date recommendation about statins are recommended.

Risk assessment of atherosclerotic cardiovascular diseases before statin therapy initiation: Knowledge, attitude, and practice of physicians in Yemen

BACKGROUND

Risk evaluation of atherosclerotic cardiovascular disease (ASCVD) remains the cornerstone of primary prevention. The cardiovascular risk assessment can guide the decision-making on various preventive measures such as initiating or deferring statin therapy. Thus, our study aimed to assess the physicians' knowledge, attitude, and practices regarding atherosclerotic cardiovascular diseases risk assessment. Also, we evaluated the physician-patient discussion and counseling practices before statin therapy initiation in concordance with recommendations from the latest clinical practice guideline.

METHODS

A cross-sectional study was conducted between November 2020 and January 2021. A self-administered questionnaire was distributed to 350 physicians (GPs, residents, specialists, and consultants). Two trained pharmacists distributed the questionnaires in 5 major tertiary governmental hospitals and more than ten private hospitals. Also, private clinics were targeted so that we get a representative sample of physicians at different workplaces.

RESULTS

A total of 270 physicians filled the questionnaire out of 350 physicians approached, with 14 being excluded due to high missing data, giving a final response rate of 73%. Participants had suboptimal knowledge and practices with a high positive attitude toward atherosclerotic cardiovascular diseases risk assessment. The knowledge and practices were higher among consultants, participants from the cardiology department, those with experience years of more than nine years, and those who reported following a specific guideline for cholesterol management or using a risk calculator in their practice. Notably, the risk assessment and counseling practices were lower among physicians who reported seeing more patients per day.

CONCLUSION

Physicians had overall low knowledge, suboptimal practices, and a high positive attitude toward cardiovascular risk assessment. Therefore, physicians' training and continuing medical education regarding cholesterol management and primary prevention clinical practice guidelines are recommended. Also, the importance of adherence to clinical practice guidelines and their impact on clinical outcomes should be emphasized.
