Medication adherence: measurement methods and approaches.

Medication adherence is crucial for optimal treatment outcomes, yet many patients struggle to follow their prescribed regimens, impacting patients, families, and healthcare systems. Measurement of adherence is vital for effective care planning and intervention. This review explores medication adherence challenges and measurement methods, including therapeutic drug monitoring (TDM), medication event monitoring system (MEMS), analysis of adherence in insurance/pharmacy database, pill counts, and self-reports, each with its advantages and limitations.This review advocates a partnership-based approach to adherence, stressing standardized reporting and team-based care. Adherence is influenced by many factors such as complex regimens, packaging, patient perspectives, side effects. Effectively addressing these factors is crucial for improving patient outcomes. In summary, medication adherence is vital but complex. The article covers various adherence measurement methods to promote medication adherence as an important matter (Tab. 5, Fig. 2, Ref. 91). Text in PDF www.elis.sk Keywords: medication adherence, adherence barriers, primary non-adherence, medication event monitoring system, pill count, self-report.

Effectiveness and Process Evaluation of Using Digital Health Technologies in Pharmaceutical Care in Low- and Middle-Income Countries: A Systematic Review of Quantitative and Qualitative Studies.

Introduction: Digital health technology (DHT) has the potential to enhance remote health care delivery. However, little is known about the effectiveness of DHTs and factors that contribute to the limited uptake of DHTs in low- and middle-income countries (LMICs). Therefore, the objective of this study was to systematically review the effectiveness and evaluation process concerning the use of DHTs in pharmaceutical care in LMICs. Methods: A literature search on PubMed and Embase was conducted to identify experimental, descriptive, qualitative, and mixed-method studies that focused on the use of DHTs in pharmaceutical care as the main intervention, reported on the effects and/or the process of the DHT intervention, were performed by pharmacists, were conducted in LMICs, and had been published in English. Two reviewers independently conducted the study selection process. A qualitative narrative review of the effectiveness of using DHTs was conducted evaluating the population, intervention, comparators, and outcomes. We summarized the content and identified themes of the evaluation process under two categories-challenges and opportunities. Results: The search produced 589 studies, of which 16 met the eligibility criteria. The most common type of DHT was mobile health application (mHealth app; n = 8), followed by mobile phone call (n = 6) and mobile video call (n = 2). Eight studies assessed the effectiveness of using DHTs in pharmaceutical care. mHealth app, mobile phone call, mobile video call, text messages, home telemonitoring, and internet-based drug information centers improved some health-related outcomes. Two of these eight studies, however, did not find significant effects of a phone call or an mHealth app on certain health-related outcomes. Of the seven quantitative studies conducting a process evaluation, all showed that patients were satisfied with the use of DHTs in pharmaceutical care provided by pharmacists. Of the two mixed-methods and one qualitative study assessing the process evaluation concerning DHT usage, three distinct themes of challenges (patient-, DHT-, and health care system-related challenges) and opportunities (patient-, DHT-, and pharmacist-related opportunities) were identified. Conclusions: DHT is a promising approach in pharmaceutical care toward improving health-related outcomes in LMICs, despite the variable intervention effects. The challenges and opportunities identified are important considerations when developing and implementing DHTs in pharmaceutical care in LMICs.

Travellers' diarrhoea - prevention, trends and role of microbiome.

OBJECTIVES: In this review, we present a contemporary look at the management of travellers' diarrhoea (TD), and we discuss the potential role of a microbiome as well as the administration of live microorganisms in order to prevent TD. METHODS: We performed a comprehensive search using the PubMed and Web of Science databases for the period 2014-2021, looking for original and review articles on travellers' diarrhoea. RESULTS: TD belongs among the most frequent illnesses experienced by travellers. For the most part, it is manifested as an acute yet self limiting condition, and only in a few cases proceeds to a prolonged form. Epidemiological analyses have shown that the majority of TD cases are caused by bacterial infections. In practice, pharmacological therapy is often used in the prevention and treatment of TD, since patients naturally seek preventive measures against the development of its severe course and its impact on planned activities. Bismuth salicylate is a strongly recommended TD prophylaxis but is not available on all European Union markets. Although the antibiotic prophylaxis is not generally recommended in guidelines, some antibiotic or chemotherapeutic agents are accessible over-the-counter in certain countries, and travellers are routinely encouraged to use them preventively. This routine can alter the microbiome of the traveller and promote the spread of drug resistant bacteria in their place of residence. Probiotic administration is considered safe, although the quality of evidence in favour of its prophylactic use in TD is currently low. CONCLUSIONS: The challenge for public health authorities is to educate personnel that can directly influence the behaviour of travellers through safe and effective pharmacological alternatives to antibiotics. Manipulation of the gut microbiome using specific probiotic strains can represent a safe and promising intervention.

Secondary prevention after acute coronary syndrome.

Patients suffering acute coronary syndrome have a very high risk for a repeated syndrome. After stabilization of acute coronary syndrome and discharge of a patient it is important to educate the patient how to prevent it in the future (dietary and life style changes), but treatment of all cardiovascular risk factors/diseases, as hypertension, dyslipidemia, diabetes but stabilization of all cardiovascular diseases is also important. Important is also antithrombotic treatment (mostly double antiplatelet treatment when percutaneous coronary intervention was used with a coronary stents), RAAS blockers, betablockers and statins (strong as atorvastatin and rosuvastatin in the highest possible dose). There are also new risk factors, and vascular inflammation belongs here. We have nowadays also some successful clinical studies how to block inflammation and how to use this treatment. A good secondary cardiovascular prevention is able to improve enourmously prognosis of these patients.

Patient-related characteristics associated with non-persistence with statin therapy in elderly patients following an ischemic stroke.

PURPOSE: This study was aimed at evaluating the extent of non-persistence with statin therapy in elderly patients after an ischemic stroke and identifying patient-related characteristics that are risk factors for non-persistence. METHODS: The evaluable study cohort (n = 2748) was derived from the database of the largest health insurance provider in the Slovak Republic. Patients aged ≥65 years who were initiated on statin therapy following the diagnosis of an ischemic stroke during one full year (1 January 2010 to 31 December 2010) constituted this cohort. Each patient was followed for a period of 3 years from the date of the first statin prescription. Patients with a continuous treatment gap of 6 months without statin prescription were designated as non-persistent. The Cox proportional hazard model was applied to determine patient-associated characteristics that influenced the likelihood of non-persistence. RESULTS: During the 3-year follow-up period, 39.7% of patients in the study cohort became non-persistent. Factors associated with decreased probability of a patient becoming non-persistent were age ≥75 years (hazard ratio (HR) 0.75), polypharmacy (concurrent use of ≥6 drugs) (HR 0.79), diabetes mellitus (HR 0.80), dementia (HR 0.81) and hypercholesterolemia (HR 0.50). On the other hand, the presence of anxiety disorders (HR 1.33) predicted an increased likelihood of a patient being non-persistent. CONCLUSIONS: Our findings suggest that patients aged ≥75 years or those with the presence of diabetes mellitus, dementia, hypercholesterolemia or polypharmacy were likely to be persistent with statin therapy, whereas those with anxiety disorders may need greater assistance with persistence of statin therapy.

INTRODUCTION OF HEALTH TECHNOLOGY ASSESSMENT FOR MEDICINES IN SLOVAKIA.

OBJECTIVES: The aim of our study was to describe approaches to health technology assessment (HTA) for medicines in the Slovak healthcare system and the related decision-making processes concerning reimbursement for medicines. METHODS: Analysis of the Slovak legislative framework related to HTA and the reimbursement process for medicines was performed. Additionally, current practices of the Working Group for Pharmacoeconomics, Clinical Outcomes and Health Technology Assessment of the Slovak Ministry of Health were evaluated. RESULTS: In Slovakia, there is always at least one treatment available in each determined therapeutic class with no co-payment. HTA is becoming an established method for the evaluation of cost-effectiveness of medicines in Slovak healthcare policy. The majority of decision makers within Slovakia support the idea of increased use of and the quality and efficiency of HTA methods. However, it is crucial to overcome several practical barriers to facilitate progress in the field of HTA in the Slovak Republic. CONCLUSIONS: It can be seen that participation within the European Network for Health Technology Assessment (EUnetHTA JA 2 and EUnetHTA JA 3 projects) has significantly improved the quality of the process of HTA in Slovakia. Further legislative activities in this field are required due to the approved strategy for European Union cooperation on HTA.

Non-persistence with antiplatelet therapy in elderly patients after a transient ischemic attack.

BACKGROUND: Antiplatelet therapy following a transient ischemic attack (TIA) constitutes an important secondary prevention measure. AIMS: The study was aimed at evaluating the development of non-persistence with antiplatelet therapy in elderly patients after a TIA and identifying patient-related characteristics associated with the probability of non-persistence during the follow-up period. METHODS: The study cohort (n = 854) was selected from the database of the largest health insurance provider of the Slovak Republic. It included patients aged ≥65 years, in whom antiplatelet medication was initiated following a TIA diagnosis during the period between 1 January 2010 and 31 December 2010. Each patient was followed for a period of 3 years from the date of the first antiplatelet medication prescription associated with TIA diagnosis. Patients in whom there was a treatment gap of at least 6 months without antiplatelet medication prescription were defined as "non-persistent". The factors predicting non-persistence were identified in the Cox proportional hazards model. RESULTS: At the end of the follow-up period, 345 (40.4%) patients were non-persistent with antiplatelet medication. Protective factors decreasing a patient´s likelihood of becoming non-persistent were age ≥75 years [hazard ratio (HR) = 0.75], polypharmacy (concurrent use of ≥6 drugs) (HR = 0.79), arterial hypertension (HR = 0.68), diabetes mellitus (HR = 0.74), hypercholesterolemia (HR = 0.75), and antiplatelet medication switching during the follow-up period (HR = 0.73). CONCLUSIONS: It is concluded that following a TIA, elderly patients aged <75 years or those with normal serum cholesterol levels, without certain comorbid conditions and polypharmacy may benefit from special counselling to encourage persistence with secondary preventive medication.

DEL-FINE: a new tool for assessing the delirogenic properties of drugs of relevance for European pharmacotherapy.

This article presents a list of potentially delirogenic properties of drugs that are currently of relevance to drug therapy in Europe, which was created through a Delphi process including experts from professions relevant to diagnosis and treatment of delirium. The Diagnostic and Statistical Manual of Mental Disorders 5 (DSM 5) defines delirium as a disturbance in attention, awareness and cognition that develops over a short period of time and fluctuates. Possible causes of delirium are manifold: usually delirium is considered to develop in a multifactorial way, caused by inalterable parameters, such as advanced age and pre-existing cognitive impairment and precipitated by modifiable parameters, such as the use of certain drugs or substance withdrawal. Delirium is a serious condition with a pronounced impact on morbidity, mortality and costs to the healthcare system. Circumstances and drugs that might precipitate or worsen delirium should therefore be avoided whenever possible. A list of drugs that might have a detrimental influence on the emergence and duration of delirium has been created using the terms "delirogenity" and "delirogenic" to describe the potential of a drug or withdrawal to cause or worsen delirium. The results are novel and noteworthy, as their focus is on substances relevant to European pharmacotherapy. Furthermore, they represent a methodical consensus from a group of experts of a wide variety of professions relevant to the prevention, diagnosis and treatment of delirium, such as nursing, pharmacy, pharmacology, surgical and internal medicine, neurology, psychiatry, intensive care and medicine, with working, teaching and scientific experience in several European countries practicing both in primary and secondary care.

Influence of hospitalisation on the use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in elderly hypertensive patients.

BACKGROUND AND AIMS: The underutilization of beneficial cardiovascular medications such as angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) in the elderly patients continues to be a matter of concern. The aim of the presented study was to compare the prescription of ACEI and ARB in elderly hypertensive patients at the time of hospital admission and discharge and to identify patient-related factors which determine the prescription of ACEI/ARB. METHODS: The study sample (n = 1111) was selected from 2,157 patients hospitalised at long-term care departments of three municipal hospitals during the period between January 1, 2008 and December 31, 2009 and included hypertensive patients aged ≥65 years suffering from myocardial infarction, heart failure, atrial fibrillation, diabetes mellitus or nephropathy. RESULTS: In hypertensive patients with myocardial infarction, diabetes mellitus and nephropathy, a significant increase was found in the use of ACEI/ARB during hospitalisation. However, there was no similar change in the use of such medications during hospitalisation in patients with heart failure and atrial fibrillation. Age ≥85 years (OR = 0.59 and OR = 0.50 at hospital admission and discharge, respectively), depression (OR = 0.63 at hospital discharge) and the systolic blood pressure ≤115 mmHg (OR = 0.45 at hospital discharge) decreased the probability of ACEI/ARB prescription. On the other hand, increasing the number of evaluated co-morbid conditions increased the patient's likelihood of being an "ACEI/ARB user" (OR = 1.20 at hospital discharge). CONCLUSIONS: Our study has identified a subset of elderly hypertensive patients (with heart failure, atrial fibrillation) in whom the use of ACEI/ARB could be improved.

Findings from the Indonesian family life survey on patterns and factors associated with multimorbidity.

The prevalence of multimorbidity tends to increase with age, but it is now also reported in the middle-aged population, which has a negative impact on healthcare systems and health outcomes. This study aims to analyze the patterns and factors associated with multimorbidity in Indonesia. This national cross-sectional population-based survey used publicly available data from the Indonesian Family Life Survey (IFLS-5) for 2014 among middle-aged (40-59 years old) and elderly (≥ 60 years old) respondents. Information on all chronic diseases was assessed using a self-reported questionnaire. Sociodemographic and health-related behavioral factors were obtained from self-reported data. Binary logistic regression analysis was used to identify the factors associated with multimorbidity. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were reported. The study recruited 11,867 respondents. The prevalence of multimorbidity was 18.6% (95% CI 17.9-19.3) with which 15.6% among middle age (95% CI 14.95-16.25) and 24.9% among the elderly (95% CI 24.12-25.68). Hypertension was the most commonly reported disease (23.2%) in all combinations of multimorbidity and among all age groups. Socio-demographic factors: elderly (AOR: 1.66; 95% CI 1.46-1.89), female (AOR: 1.42; 95% CI 1.20-1.69), living in the urban area (AOR: 1.22; 95% CI 1.09-1.38), higher educational level (AOR: 2.49; 95% CI 1.91-3.26), unemployed (AOR: 1.63; 95% CI 1.44-1.84), and higher economic level (AOR: 1.41; 95% CI 1.18-1.68) were associated with multimorbidity. Poor health behavior factors: being former smokers (AOR: 2.03; 95% CI 1.65-2.51) and obesity (AOR: 1.53; 95% CI 1.35-1.75) were also associated with multimorbidity. The prevalence of multimorbidity in the middle-aged and elderly population in Indonesia is relatively high, particularly in populations with poor health behaviors. Therefore, healthcare professionals should integrate more patient-specific factors when designing and implementing tailored interventions to manage multimorbidity in Indonesia.

High Emergence of Multidrug-Resistant Sequence Type 131 Subclade C2 among Extended-Spectrum ß-Lactamase (ESBL)-Producing Escherichia coli Isolated from the University Hospital Bratislava, Slovakia.

The expansion of sequence type 131 (ST131) extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli (E. coli) represents major worldwide challenges. E. coli strains originating from healthcare facilities (labeled No. 1 and No. 2) of the University Hospital Bratislava (UHB) were analyzed for ST131 emergence, including its (sub)lineages and clonal relatedness. Antimicrobial resistance was determined in most strains. Of a total of 354 E. coli strains, 263 (74.3%) belonged to ST131; of these, 177 (67.3%) were from No. 1. Generally, among 260 ST131 E. coli, clades A/B were confirmed in 20 (7.7%), while clade C was noted in 240 (92.3%) strains; within them, subclades were detected as follows: C0 (17; 7.1%), C1 (3; 1.2%), and C2 (220; 91.7%). Among fifteen randomly selected E. coli strains that were investigated for ST and clonal relatedness, seven STs were identified: eight (53.3%) ST131, two (13.3%) ST73, and one each (6.7%) of ST10, ST12, ST14, ST1193, and ST1196. From No. 1, two ST131 in the first internal clinic and one ST131 from No. 2 in the aftercare department were highly clonally related, suggesting possible epidemiological association. Antimicrobial resistance was as follows: ciprofloxacin 93.8%, ceftazidime 78.4%, meropenem 0%, fosfomycin 2.9% and nitrofurantoin 1.4%. Prevention of ESBL-producing E. coli dissemination, especially for ST131 clade C2, is inevitably necessary for reducing drug resistance and decreasing healthcare-associated infections.

Acute drug intoxication in childhood: a 10-year retrospective observational single-centre study and case reports.

BACKGROUND: Medication poisoning in children is a severe condition that can endanger a child's life. Although drug intoxications are easily preventable, awareness of the proper handling of drugs and their safe storage out of the reach of children is not widespread among the general public. In this work, we investigated the demographic and clinical data of children admitted to the Department of Pediatrics of the University Hospital Olomouc for acute drug-induced intoxication. We also selected several case reports to illustrate the wide range of both presentations and outcomes in individual patients. METHOD: Cases of drug-induced intoxications were selected from a group of patients under the age of 19 years admitted to the hospital for poisoning between January 1, 2010, and December 31, 2019. Medical records of these patients were prospectively evaluated, and overview tables and graphs of predefined research objectives were created. RESULTS: During the given time period, 162 children with suspected drug intoxications were hospitalized at the Department of Pediatrics, University Hospital Olomouc. Of these, 108 cases were reported in girls and 54 in boys (66.7% vs. 33.3%). In 16 cases (9.9%), there was a severe intoxication requiring follow-up intensive care. There was also one case of fatal accidental intoxication. Most poisonings were seen in toddlers (65; 40.1%). Intoxication with suicidal ideation was found in 44 cases (27.2%), with a higher incidence of suicide attempts in girls (40 vs. 4). Repeated intoxication was recorded in nine cases. Analgesics were the most common drug group (61; 37.7%), with paracetamol (28; 17.3%) being the leading drug. In 154 cases (95.1%), the drugs were taken orally, most often in the form of tablets. CONCLUSION: Accidental drug intoxications most frequently occurred in the age group from one to three years old. The second highest incidence was among adolescents most of which were suicide attempts. Analgesics and psychoactive agents accounted for the majority of cases. Medications should be kept in places where children cannot reach them.

Reinitiation and Subsequent Discontinuation of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers among New and Prevalent Users Aged 65 Years or More with Peripheral Arterial Disease.

Angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin-receptor blockers (ARBs) are recommended in the treatment of arterial hypertension in patients with peripheral arterial disease (PAD). The aims of our study were: (a) to analyse the extent of reinitiation and subsequent discontinuation in older hypertensive PAD patients non-persistent with ACEIs/ARBs; (b) to determine patient and medication factors associated with reinitiation and subsequent discontinuation; and (c) to compare these factors between prevalent and new users. The analysis of reinitiation was performed on a sample of 1642 non-persistent patients aged ≥65 years with PAD newly diagnosed in 2012. Patients reinitiating ACEIs/ARBs were used for the analysis of subsequent discontinuation identified according to the treatment gap period of at least 6 months without any prescription of ACEI/ARB. In the group of non-persistent patients, 875 (53.3%) patients reinitiated ACEIs/ARBs during a follow-up (24.8 months on average). Within this group, subsequent discontinuation was identified in 414 (47.3%) patients. Being a new user was associated with subsequent discontinuation, but not with reinitiation. Myocardial infarction during non-persistence and after reinitiation was associated with reinitiation and lower likelihood of subsequent discontinuation, respectively. Being a prevalent or a new user is associated with the use of medication also after initial discontinuation.

Factors associated with non-adherence to angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in older patients with peripheral arterial disease.

Introduction: As in other chronic conditions, medication adherence is important in the treatment of peripheral arterial disease (PAD). Our study aimed at a) analysing non-adherence to angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in groups of older ACEI and ARB users with PAD, and b) identifying characteristics associated with non-adherence. Methods: We focused on the implementation phase of adherence (i.e., after treatment initiation and before possible discontinuation of treatment). The study cohort included ACEI/ARB users aged ≥65 years in whom PAD was newly diagnosed during 2012. Non-adherence was defined as Proportion of Days Covered (PDC) < 80%. Results: Among 7,080 ACEI/ARB users (6,578 ACEI and 502 ARB users), there was no significant difference in the overall proportion of non-adherent patients between ACEI and ARB users (13.9% and 15.3%, respectively). There were differences in factors associated with non-adherence between the groups of persistent and non-persistent (i.e., discontinued treatment at some point during follow-up) ACEI and ARB users. Increasing age, dementia and bronchial asthma were associated with non-adherence in persistent ACEI users. General practitioner as index prescriber was associated with adherence in the groups of non-persistent ACEI users and persistent ARB users. Conclusion: Identified factors associated with non-adherence may help in determining the groups of patients who require increased attention.

The use of medications with anticholinergic properties and risk factors for their use in hospitalised elderly patients.

PURPOSE: The aims of the present study were to evaluate the use of drugs with anticholinergic properties in elderly patients and to identify risk factors that increase the patient's chance of being given such medications. METHODS: The study was performed on a sample of 1636 patients aged ≥65 years hospitalised during the period between 1 January 2008 and 31 December 2009 in three municipal hospitals. To evaluate the factors influencing the use of anticholinergic medications, we compared two groups-users and non-users of such drugs-in terms of sociodemographic and clinical characteristics as well as comorbid conditions. The most important risk factors were identified using the binary logistic regression model. RESULTS: Hospitalisation led to a significant increase in the prevalence of anticholinergic medication users, when comparing their occurrence at the time of hospital admission and discharge (10.5% and 14.2%, respectively; p < 0.001). A significantly higher total number of prescribed drugs were found in the group of users compared with non-users, at both hospital admission (7.2 ± 3.5 vs 5.7 ± 3.1; p < 0.001) and discharge (8.7 ± 3.1 vs 7.5 ± 2.9; p < 0.001). Immobilisation, urinary incontinence and retention, constipation, gastroduodenal ulcer disease as well as neurologic and psychiatric comorbidities (depression, Parkinson's disease, epilepsy) appeared as the most important risk factors of using anticholinergic medications. CONCLUSIONS: Physicians should be aware of the greater risk of adverse anticholinergic effects of drugs in certain therapeutic classes in the elderly. In patients with risk factors mentioned previously, special attention should be paid to active identification of anticholinergic effects of medications.

Orally Administered Probiotics in the Prevention of Chemotherapy (± Radiotherapy)-Induced Gastrointestinal Toxicity: A Systematic Review With Meta-Analysis of Randomized Trials.

BACKGROUND: Chemoradiotherapy-induced gastrointestinal toxicity may lead to a significant impairment of the oncological patient's quality of life, as well as to reduced adherence to the treatment, which may have a negative impact on survival and mortality rates. OBJECTIVE: The aim of this review was to investigate whether oral probiotic administration prevents chemotherapy (± radiotherapy)-induced gastrointestinal toxicity, particularly diarrhea. METHODS: We searched the MEDLINE, Web of Science, and SCOPUS databases for randomized controlled trials in English published between 1990 and 2020. We conducted statistical data analyses expressing the treatment effect size as a risk ratio (RR) together with a 95% confidence interval (CI). Implications are based on trials rated as having a low risk of bias (RoB). RESULTS: We included 8 trials (n = 697 participants), from which 3 studies rated as low RoB contained primary endpoint data; the risk of developing grade 3/4 diarrhea in patients receiving probiotics was reduced by 78% compared to the control group (RR = 0.22 [95% CI 0.05-1.08]; P = .06; n = 114 participants). Probiotics showed preventive effects in patients treated with chemotherapy alone (RR = 0.34 [0.12-0.94]; P = .04, n = 121 participants) and in patients with colorectal cancer (RR = 0.56 [0.34-0.92]; P = .02; n = 208 participants). The reduction in the incidence of overall diarrhea was not significant. CONCLUSIONS: Probiotics failed to prove a preventive effect of statistical significance against the development of severe and overall diarrhea in cancer patients treated with chemotherapy (± radiotherapy). However, we cannot rule out that the effects of probiotics are clinically relevant, especially in certain subgroups of patients. This needs to be clarified in further well-performed studies.

Gender Differences in Non-Persistence with Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers among Older Hypertensive Patients with Peripheral Arterial Disease.

The beneficial effects of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in hypertensive patients with peripheral arterial disease (PAD) depends on long-term persistence. The aims of our study were to analyse gender differences in non-persistence with ACEIs/ARBs, and to identify the characteristics associated with the likelihood of non-persistence. Our study cohort included 7080 hypertensive patients (4005 women and 3075 men) aged ≥65 years, treated with ACEIs/ARBs, in whom PAD was diagnosed between 1 January and 31 December 2012. Non-persistence was identified according to a treatment gap of 6 months without ACEI/ARB prescriptions. The characteristics associated with non-persistence were identified using the Cox regression model. At the end of the 5-year follow-up, 23.2% of the whole study cohort, 22.3% of men, and 23.9% of women were non-persistent with ACEIs/ARBs, with no significant gender differences in persistence. While a number of characteristics were associated with non-persistence, only three characteristics had consistent, statistically significant associations in both genders: being a new ACEI/ARB user increased the likelihood of non-persistence, and general practitioner as index prescriber and increasing the overall number of medications decreased the likelihood of non-persistence. Information on the differences in characteristics that are associated with non-persistence between genders may help to better identify patients for whom special attention should be paid to improve their persistence.

Histamine Intolerance-The More We Know the Less We Know. A Review.

The intake of food may be an initiator of adverse reactions. Food intolerance is an abnormal non-immunological response of the organism to the ingestion of food or its components in a dosage normally tolerated. Despite the fact that food intolerance is spread throughout the world, its diagnosing is still difficult. Histamine intolerance (HIT) is the term for that type of food intolerance which includes a set of undesirable reactions as a result of accumulated or ingested histamine. Manifestations may be caused by various pathophysiological mechanisms or a combination of them. The problem with a "diagnosis" of HIT is precisely the inconstancy and variety of the manifestations in the same individual following similar stimuli. The diagnosing of HIT therefore requires a complex time-demanding multidisciplinary approach, including the systematic elimination of disorders with a similar manifestation of symptoms. Among therapeutic approaches, the gold standard is a low-histamine diet. A good response to such a diet is considered to be confirmation of HIT. Alongside the dietary measures, DAO supplementation supporting the degradation of ingested histamine may be considered as subsidiary treatment for individuals with intestinal DAO deficiency. If antihistamines are indicated, the treatment should be conscious and time-limited, while 2nd or 3rd generation of H1 antihistamines should take precedence.

Consumption of Antibacterials for Systemic Use in Slovakia: A National Study and the Quality Indicators for Outpatient Antibiotic Use.

This paper aims to analyse the consumption of antibiotics in the Slovak health care system from 2011 to 2020. The data source on the consumption of antibiotics is sales data from SUKL and NCZI. The study employed the ATC/DDD Index and focused on the consumption of antibiotics in the primary care sector. Total antibiotic consumption decreased from 19.21 DID in 2011 to 13.16 DID in 2020. Consumption of beta-lactamase-sensitive penicillins, expressed as a percentage of the total consumption of antibiotics, decreased from 8.4% in 2011 to 4.2% in 2020. Consumption of the combination of penicillins, including beta-lactamase inhibitor, expressed as a percentage of the total consumption of antibiotics, increased from 16.2% in 2011 to 17.9% in 2020. Consumption of third- and fourth-generation cephalosporins, expressed as the percentage of the total consumption of antibiotics, increased from 2.0% in 2011 to 4.6% in 2020. Consumption of fluoroquinolones, expressed as the percentage of the total consumption of antibiotics, decreased from 10.7% in 2011 to 8.6% in 2020. Overall, antibiotic consumption significantly changed in Slovakia from 2011 to 2020. The ratio of the consumption of broad-spectrum to the consumption of narrow-spectrum penicillins, cephalosporins and macrolides decreased from 14.98 in 2011 to 13.38 in 2020.

Non-Persistence With Antiplatelet Medications Among Older Patients With Peripheral Arterial Disease.

Introduction: Antiplatelet therapy needs to be administered life-long in patients with peripheral arterial disease (PAD). Our study was aimed at 1) the analysis of non-persistence with antiplatelet medication in older PAD patients and 2) identification of patient- and medication-related characteristics associated with non-persistence. Methods: The study data was retrieved from the database of the General Health Insurance Company. The study cohort of 9,178 patients aged ≥ 65 years and treated with antiplatelet medications was selected from 21,433 patients in whom PAD was newly diagnosed between 01/2012 and 12/2012. Patients with a 6 months treatment gap without antiplatelet medication prescription were classified as non-persistent. Characteristics associated with non-persistence were identified using the Cox regression. Results: At the end of the 5 years follow-up, 3,032 (33.0%) patients were non-persistent. Age, history of ischemic stroke or myocardial infarction, clopidogrel or combination of aspirin with clopidogrel used at the index date, higher co-payment, general practitioner as index prescriber and higher overall number of medications were associated with persistence, whereas female sex, atrial fibrillation, anxiety disorders, bronchial asthma/chronic obstructive pulmonary disease, being a new antiplatelet medication user (therapy initiated in association with PAD diagnosis), and use of anticoagulants or antiarrhythmic agents were associated with non-persistence. Conclusion: In patients with an increased probability of non-persistence, an increased attention should be paid to improvement of persistence.
