Dyslipidemias are defined as a wide range of abnormalities of the lipid profile. Treatment guidelines recommend aiming at lowering LDL-C. We investigated the adherence of Czech cardiologists to the dyslipidaemia treatment guidelines, especially in the management of patients with high and very high cardiovascular risk. In this retrospective cross-sectional multicentric study data from medical records of 450 adults with ASCVD, enrolled between June 2021 and January 2022, were analysed. Demographics, clinical outcomes, medical history, LLT treatment and other medications were collected. The physicians were to include patients at a very high risk of ASCVD and to complete a general questionnaire on their personal therapeutic preferences. Objectively assessed, only 80% of total patients (N = 450) enrolled in the study were at very high risk of ASCVD, and 12.7% of patients were at high risk of ASCVD, respectively. In total, 55 (13.1%) patients were diagnosed with familial hypercholesterolemia, and 39.1% of them had a positive family history of ASCVD. Generally, only 20.5% of patients reached the 2019 LDL-C goals– 19.4% of very high risk patients and 28.1% of high risk patients, respectively. 61% of the physicians preferred a slow and careful up-titration of the dose, which is contradictory to the guidelines. Only 17% of the physicians increased the statin dose or added/combined/changed the treatment to achieve the LDL-C goals as soon as possible. Surprisingly, in up to 61.5% of patients at very high risk who did not meet the LDL-C goals, their physicians stated subjective satisfaction with the treatment and considered no change needed. Among very high and high risk patients receiving lipid-lowering therapy, with high treatment adherence, the LDL-C goal attainment is very low and LLT utilization is rather sub-optimal. Improving observance of the guidelines by physicians bears a substantial potential for LDL-C goal attainment and thus improving overall benefit for patients for no additional costs.

Managed Entry Agreements (MEAs) play a pivotal role in addressing the challenges arising from escalating prices of innovative medical technologies, especially in areas like oncology, immunology, and rare diseases. Among MEAs, Performance-Based MEAs (PB MEAs) and Outcome-Based MEAs (OB MEAs) stand out as innovative strategies. This study examines the adoption of PB MEAs in the Czech Republic post a 2022 legislative change. Interviews with key stakeholders, including the Ministry of Health, pharmaceutical companies, insurers, and patient groups, were conducted to explore perceptions and challenges. Stakeholders expressed concerns about legislation completeness, data quality, transparency, and methodology. Interestingly, pharmaceutical companies were less concerned about transparency and methodology, likely due to their multinational experience. Despite legislative progress, challenges persist, especially in data infrastructure, risk-sharing perceptions, and stakeholder readiness. Addressing these issues requires collaboration between pharmaceutical companies and payers. Patient involvement, though mandated, remains limited, potentially due to a lack of awareness. This study emphasizes the need for a comprehensive transformation beyond legislation for a successful PB MEA implementation. Trust, technical infrastructure, and data availability are crucial, necessitating a holistic approach. It contributes to the global discourse on PB MEAs, stressing the adjustment of financial frameworks, embracing value-based healthcare principles, and ensuring high-quality health data metrics. A more holistic, value-based MEA approach could reshape pharmaceutical reimbursement in the future.

The pandemic caused by the SARS-CoV-2 virus is believed to originate in China from where it spread to other parts of the world. The first cluster of diseased individuals was reported in China as early as in December 2019. It has also been well established that the virus stroke Italy later in January or in February 2020, hence distinctly after the outbreak in China. The work by Apolone et al. published in the Italian Medical Journal in November 2020 and retracted upon expression of concern on 22 March 2021, however propose that the virus could have stroke people already in September 2019, possibly following even earlier outbreak in China. By fitting an early part of the epidemic curve with the exponential and extrapolating it backwards, we could estimate the day-zero of the epidemic and calculated its confidence intervals in Italy and China. We also calculated how probable it is that Italy encountered the virus prior 1 January 2020. We determined an early portion of the epidemic curve representing unhindered exponential growth which fit the exponential model with high determination >0.97 in both countries. We conservatively suggest that the day-zero in China and Italy was 8 December 2019 (95% CI: 3 Dec., 20 Dec.) and 22 January 2020 (95% CI: 16 Jan., 29 Jan.), respectively. Given the uncertainty of the very early data in China and adjusting hence our model to fit the exponentially behaved data only, we can even admit that the pandemic originated through November 2019 (95% CI: 31 Oct., 22 Dec.). With high confidence (p <0.01) China encountered the virus prior Italy. We generally view any pre-pandemic presence of the virus in humans before November 2019 as very unlikely. The later established dynamics of the epidemics data suggests that the country of the origin was China.

Background: There has been a noticeable relative increase in psychiatric comorbidities among smokers as opposed to the general population. This is likely due to comparatively slower decrease in smoking prevalence among individuals with mental health conditions. This study aims to assess the prevalence trend of past or current mental health disorders in individuals seeking specialized smoking cessation assistance. Methods: We conducted a retrospective single-centre observational study to assess the presence of mental disorders such as anxiety, depression, bipolar affective disorder, or schizophrenia in personal history of 6,546 smokers who sought treatment at the Centre for Treatment of Tobacco Dependence in Prague, Czech Republic between 2006 and 2019. The study examined the impact of gender, age, and the effect of successive years on the prevalence of the mental disorders using Poisson distribution regression. Results: In the studied cohort, 1,743 patients (26.6%) reported having one or more mental disorders. Compared to patients without a psychiatric disorder, they exhibited similar levels of carbon monoxide in expired air (mean 17 ppm, SD 11 ppm) and scored one point higher on the Fagerström Test of Cigarette Dependence. Among smokers with a mental disorder, women were more prevalent (62%) than men (38%). The prevalence of mental disorders increased on average by 4% every year, rising from 23% in 2006 to 35% in 2019. Conclusions: Consistent with the observation that the prevalence of smoking among people with any mental disorder is higher and declining at a slower rate than in the general population, there is a steadily increasing percentage of these patients seeking specialized treatment over time. Professionals who offer tobacco dependence treatment should be aware of the upward trend in psychiatric disorders among smokers, as more intensive treatment may be needed. Similarly, psychiatric care should pay attention to smoking of their patients.

Background: Dyslipidaemia is a key risk factor for atherosclerotic cardiovascular disease (ASCVD), necessitating effective statin therapy. Despite statins’ proven safety and efficacy, adherence remains suboptimal, with significant gaps between clinical practice and guideline recommendations. Methods: This retrospective cohort study analysed anonymized health administrative claims data from six employee health funds in the Czech Republic, covering approximately 40% of the insured population from January 1, 2017, to December 31, 2020. We identified statin-incident as well as prevalent cohort of patients. Adherence to statin therapy was assessed using the proportion of days covered (PDC) metric, with factors such as age, gender, sequence of use, and treatment intensity considered as modifiers. Results: Among the statin-prevalent cohort (SP, n = 890,180), 83.5% achieved a PDC ≥ 50%, and 61.0% reached a PDC ≥ 80%. In the statin-incident cohort (SI, n = 287,871), a clear trend of increasing adherence with age and medication sequence was observed: in adults aged 18–39 median PDC rose from 84.1% (IQR: 57–100) in the first to 94.7% (IQR: 75.6–100) in the third sequence; in those aged 80 + median PDC rose from 95.0% (IQR: 68.9–100) in the first to 100% (IQR: 78.3–100) in the third sequence. Logistic regression identified age (OR=1.011 per year), female gender (OR=0.896), high-intensity treatment (OR=0.975), and second (OR=1.267) or later treatment sequences (OR=1.704) as significant predictors of adherence (all p < 0.001). Conclusion: Adherence to statin therapy improves with subsequent treatment sequences and age. These findings highlight the need for targeted interventions to enhance adherence, particularly among younger patients. The PDC metric is recommended for integration into clinical practice to monitor and improve medication adherence.

Slovakia has adopted an amendment to Act No. 363/2011, regulating, among other things, drug reimbursement and is undergoing a significant change in the availability of innovative treatments for patients. High expectations are associated with arrangements related to performance-based managed entry agreements. Opinions and positions towards this change appear to be inconsistent, and for the further application of the law in practice and when setting up the main implementation processes, it is necessary to understand the positions and opinions of the individual actors who are involved in the PB-MEA process. The interviews were conducted in the period from 20 May to 15 August 2022 around the same time as the finalisation of the amendment to Act No. 363/2011 and its adoption. A roughly one-hour open interview was conducted on a sample of 12 stakeholders in the following groups: representatives of the Ministry of Health, health-care providers, pharmaceutical companies and others, including a health insurance company. The main objective was to qualitatively describe the perception of this topic by key stakeholders in Slovakia. The responses were analysed using MAXQDATA 2022 software to obtain codes associated with key expressions. We identified three main strong top categories of expressions that strongly dominated the pro-management interviews with stakeholders: legislation, opportunities and threats. Ambiguity and insufficient coverage of the new law, improved availability of medicinal products and threats associated with data, IT systems and potentially unfavourable new reimbursement schemes were identified as key topics of each of the said top categories, respectively. Among individual sets of respondents, there is frequent consensus on both opportunities and threats in the area of implementing process changes in PB-MEA. For the successful implementation of the law in practice, some basic threats need to be removed, among which in particular is insufficient data infrastructure.
