Analysis of medication administration in relation to food and beverages in inpatients.

Proper medication administration in relation to beverage or food is one of the essential tools to achieve the pharmacotherapy goals. It is not known whether this is also considered in the care of inpatients. The aim of this study was to describe and analyse the current practice of medication administration in relation to food and beverages to patients hospitalized in four hospitals in the Czech Republic. This study was conducted based on the results of the first phase of a prospective observation study focused on the safety of medication administration performed by nurses. All data, including the timing of medication administration in relation to food and the data on beverages used, were obtained by the method of direct observation. The team of observersaccompanied the nurse during medication administration. The appropriateness of the medication administration in relationto food/beverages was assessed according to the summary of product characteristics and the published literature. In total, the administration of 5718 oral medications and 198 insulins were analysed. Unproper food timing wasobserved in 15.7% of oral medication administrations and 26.8% of insulin administrations. The highest number ofunproper food timing occurred in the proton pump inhibitors, antihypertensives, and prokinetics. Tea (63.4%) was the most used beverage. Errors with clinically serious impact have been observed in some groups of drugs. The necessity of a systemic approach in management of medication administration is required including interdisciplinary cooperation.

Inflammatory blood parameters as prognostic factors for implant-associated infection after primary total hip or knee arthroplasty: a systematic review.

BACKGROUND: Implant-associated infection (IAI) is a potential complication following total hip (THA) or knee arthroplasty (TKA). The initial phase of the inflammatory process can be measured by applying one of the inflammatory blood parameters (IBP). This systematic review aims to assess the response of IBP to trauma caused by orthopedic surgery and evaluate the clinical utility of quantitative measurements of IBP as prognostic factors for infection. METHODS: All studies indexed in Ovid MEDLINE (PubMed), Ovid EMBASE, the Cochrane Library and the ISI Web of Science databases, from inception until January 31, 2020, were analyzed. Studies included were those on adults who underwent THA or TKA with minimum follow up of 30 days after surgery. In addition to minimum follow up, data on the prognostic factors for pre- or post-THA/TKA IAI were mandatory. The Quality Assessment of Diagnostic Accuracy tool (version 2) (QUADAS-2) and Standards for Reporting of Diagnostic Accuracy Studies guideline 2015 (STARD) were used for quality assessment. RESULTS: Twelve studies fulfilled the inclusion and exclusion criteria. C-reactive protein was analyzed in seven studies, interleukin-6 in two studies and erythrocyte sedimentation rate in eight studies. White blood cell count and procalcitonin were analyzed in the only study. The overall quality of included studies was low. A potential for other cytokines (IL-1ra, IL-8) or MCP-1 was observed. CONCLUSIONS: This is the first systematic review of IBP response to orthopedic surgery which identified some IBP for pre/post-operative screening, despite insufficient data supporting their prognostic potential for patient risk stratification.

Vitamin D: sources, physiological role, biokinetics, deficiency, therapeutic use, toxicity, and overview of analytical methods for detection of vitamin D and its metabolites.

Vitamin D has a well-known role in the calcium homeostasis associated with the maintenance of healthy bones. It increases the efficiency of the intestinal absorption of dietary calcium, reduces calcium losses in urine, and mobilizes calcium stored in the skeleton. However, vitamin D receptors are present ubiquitously in the human body and indeed, vitamin D has a plethora of non-calcemic functions. In contrast to most vitamins, sufficient vitamin D can be synthesized in human skin. However, its production can be markedly decreased due to factors such as clothing, sunscreens, intentional avoidance of the direct sunlight, or the high latitude of the residence. Indeed, more than one billion people worldwide are vitamin D deficient, and the deficiency is frequently undiagnosed. The chronic deficiency is not only associated with rickets/osteomalacia/osteoporosis but it is also linked to a higher risk of hypertension, type 1 diabetes, multiple sclerosis, or cancer. Supplementation of vitamin D may be hence beneficial, but the intake of vitamin D should be under the supervision of health professionals because overdosing leads to intoxication with severe health consequences. For monitoring vitamin D, several analytical methods are employed, and their advantages and disadvantages are discussed in detail in this review.

Safety of drug administration from the perspective of hospitalized patients in selected hospitals of the South Bohemia Region.

Drug administration is one of the riskiest areas of healthcare provision, accompanied by several possible mistakes. Patient and family involvement is crucial for patient safety in a hospital environment. The research study aimed to evaluate the subjective perception of the safety of the drug administration process from hospitalized patients point of view and their involvement in drug administration. A structured questionnaire of its own design was used to obtain data. Three hundred twenty-nine respondents from 4 hospitals in the South Bohemian Region in the Czech Republic were included in the research, including patients hospitalized in the internal medicine, surgery, and follow-up and rehabilitation care departments. We found different perceptions and individual understandings of the safety of the drug delivery process by other groups of patients. Interest in participating in drug administration also varies between groups of patients. Women control the medication given to them by the nurse to a much greater extent than men. Patients under the age of 60, patients with higher professional and university education, and patients from the surgical department would like to be more involved in deciding which aplikovadrugs to use. Patients with a low level of education want to involve their family members more in their treatment decisions. Both healthcare professionals and patients should be led by hospital management to increase patient involvement in the hospitalization process.

Medication adherence terminology - the first consensual translation using the Delphi method.

BACKGROUND: The terminology of adherence (or compliance) describing the patients medication taking behavior is often used inconsistently and fragmented in the literature. Therefore, the English original of so-called ABC Taxonomy was developed to classify and unify the terminology. The aim of this paper was to establish the first consensual translation of Czech terminology dealing with the issue of medication taking behavior using Delphi method. METHODS: In the period from February to May 2021, a three-round anonymous online Delphi questionnaire survey was conducted. The questionnaire contained items for translations of seven terms and their definitions based on the ABC Taxonomy, while the resulting consensus was established by a predefined degree of agreement of the respondents. RESULTS: Out of 106 contacted panelists representing different healthcare professions, 46 (43.4%) answered in the first round. Sufficient consensus ( 85%) was reached for the translation of two definitions. In the second round, 32 respondents managed to establish a consensus (> 75%) of one term and four definitions and 24 respondents in the third round established a mild (> 50%) to strong (> 95%) consensus for all remaining terms and definitions. The set of terms related to medication taking for the Czech language was as follows: adherence k léčbě, zahájení léčby, zavedení léčby, přerušení léčby, setrvání na léčbě, management adherence and obory související s adherencí. CONCLUSION: The consensual translations of all Czech terms and definitions related to medication adherence can contribute to greater harmonization and comparability of scientific papers as well as to enhance the communication between scientific and clinical community. However, this consensus needs to be confirmed by a larger number of experts dealing with adherence issue, including the involvement of professional societies.

Evaluation of medication errors in the hospital environment.

INTRODUCTION: Healthcare is inherently associated with a risk to patient health. One risk is associated with medication-related errors, which are commonly reported adverse events. By analyzing the root causes of medication errors, effective preventive measures can be proposed to reduce their likelihood. This study aimed to identify the reasons of medication administration errors, determine the number of medication administration errors reported, and describe the barriers hindering reporting. METHODOLOGY: The study used a standardized Questionnaire Medication Administration Error Survey (MAE survey) that was quantitatively analyzed. The study involved 112 nurses from four hospitals in the South Bohemian Region. RESULTS: Risk factors that increase the likelihood of medication administration errors include similarity of drug names (3.7 ± 1.3) and packaging (3.9 ± 1.5), frequent prescription changes for patients (3.2 ± 1.5), illegibility of written prescriptions (3.1 ± 1.6), a lack of clarity of medical records (2.6 ± 1.5). Only a proportion of medication administration errors are reported by nurses (16% to 21%). The reluctance of nurses to report medication administration errors is linked to fear of being blamed for the deterioration of the patients health (3.3 ± 1.7), fear of the doctors reaction to a medication administration error (2.6 ± 1.4), and repressive responses from hospital management to reported misconduct (2.9 ± 1.5). CONCLUSION: Measures to reduce the likelihood of medication administration errors include building a non-punitive system for reporting adverse events and medication errors, introducing electronic prescription systems, promoting open communication within the team, involving clinical pharmacists in the pharmacotherapy process, and regular comprehensive training of nursing staff.

Review of Czech literature focused on terminology of medication adherence.

BACKGROUND: Medication taking terminology is often used incorrectly or inconsistently in the world literature and the meaning of the terms is interchanged. The aim of the work was to map the Czech literature and find out whether Czech authors use terminology related to medication adherence and whether they are consistent in defining it. METHODS: Based on the methodological instructions for the translation of the so-called ABC Taxonomy introduced by International Society for Medication Adherence (ESPACOMP), a search of Czech literature published until September 22nd, 2021 in the databases ProLékaře.cz, BMČ, PubMed, and Solen was prepared. Morphological variants of keywords were used for the search: compliance, adherence, initiation, implementation, discontinuation, persistence, concordance. RESULTS: A total of 125 Czech publications from 1998 to 2021 were identified, of which 79 defined specific terms. These included: adherence, persistence, compliance, concordance; the terms for compliance and adherence were interchanged in 14 publications. Publications focused on the treatment of specific diseases were the most common. Only five sources dealt with the issue of medication adherence as a theme without relation to a specific nosological unit. CONCLUSION: Inconsistency in the use of terms related to medication adherence has proven to be a very common phenomenon in the Czech literature. It is, therefore, necessary to establish a consensus on this terminology in order to unify Czech literature.

Pharmacotherapy as major risk factor of falls - analysis of 12 months experience in hospitals in South Bohemia.

This study aimed to analyze the effect of fall risk-increasing drugs (FRIDs) and drug-related factors relative to falls through clinical pharmacy service in hospitalized patients, focusing on the relevance of clinical pharmacist evaluation in the context of physician assessment. A prospective study of inpatient falls was conducted in 2017 retrieving data from 4 hospitals in South Bohemia, Czech Republic. An online database was developed to collect patient and fall-related data, and fall evaluation records. Healthcare professionals classified the overall effect of drugs on falls using Likert scale. Univariate and multivariate correlations were performed with a significance level of p < 0.05. Out of the total 280 falls (mean age of patients 77.0 years), a mean of 2.8 diagnoses with fall-related risk, 8.8 drugs, and 4.1 FRIDs per fall were identified. Incidence of falls decreased quarterly (p < 0.001). Use of FRIDs were positively associated with increasing age (p = 0.007). Clinical pharmacists were more likely to identify pharmacotherapy as the relevant fall-related risk, compared to physicians evaluation (p < 0.001). An increasing total number of prescribed drugs as well as higher number of FRIDs increased the suspicion in both professionals in the context of drug-related causes of falls.

Clinical pharmacist involvement in fall management in a polymorbid geriatric patient with a history of recurrent falls.

Patient falls represent a significant burden on healthcare facilities, particularly by prolonging hospitalization and increasing the cost of subsequent healthcare. In most cases, fall is caused by a combination of several modifiable and unmodifiable risk factors. The pharmacotherapy, which is often unreasonably administered in relation to patient health condition and drug combination, belongs among the modifiable risk factors. In this case report, the potential effect of pharmacotherapy on the patient fall-related risk as well as clinical pharmacy service that can contribute to reducing the risk of falls by engaging of clinical pharmacist in a multidisciplinary team with focus on the risks of pharmacotherapy and their management are shown.

[Medication adherence to non-vitamin K antagonist oral anticoagulants at non-valvular atrial fibrillation - the literature review]. / Adherence k lécbe non-vitamin K perorálními antikoagulancii u nevalvulární fibrilace síní: prehled literatury.

Medication adherence is a complex problem reflecting variations in terms of medication taking behavior. It is essential in maximizing of the effect and risk minimization of the therapy and health care costs reduction, even in the case of oral anticoagulants (non-vitamin K antagonist oral anticoagulants - NOACs). The aim of this paper was to review the published literature and to discuss results in the field of medication adherence to NOACs in patients with non-valvular atrial fibrillation (NVAF). Based on the searching in databases Embase and PubMed 25 studies were identified, of which conclusions were summarized in this paper. Patients treated with dabigatran reported poorer medication adherence than patients with rivaroxaban. However, medication adherence is influenced by many circumstances as well as included studies were not sufficiently uniform, therefore, a prerequisite for further investigation of this issue is expected.Key words: apixaban - atrial fibrillation - dabigatran - medication adherence - patient compliance - rivaroxaban.

Prescription of evidence-based medicine drugs by general practitioners to patients after myocardial infarction: outcomes from the Czech Republic.

Ischemic heart disease is the most frequent cause of both serious morbidity and mortality of adult population in developed countries. The main aim of the study was to carry out the analysis of general practitioners (GP) prescription of evidence-based therapy in patients after myocardial infarction (MI). Data were retrospectively collected in 2011, by a single application with the help of software that GPs use in their surgeries. All patients of a particular GP who had MI in their history and who were at the time of data collection treated only by GPs (not by the specialists of internal medicine or cardiology) were always included. Four hundred ninety one patients were included in the study. The average age was 70.7 (+/- 11.6) and 69.2% of the involved patients were men. Seventy nine percent of patients used beta-blockers, 80% antiplatelet drugs, 77% statins and 79% used angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs/ARBs). Forty four percent of patients used drugs from all four groups. The significant prescription decrease was proved in all four groups in dependence on patients' age (p < 0.05). Although the evidence-based medicine usage in patients after MI in the Czech Republic is comparable to other countries, it is not optimal. More intensive involvement of pharmacists in the care of patients after MI would further improve the situation.

Analysis of pharmacists' opinions, attitudes and experiences with generic drugs and generic substitution in the Czech Republic.

Generic substitution (GS) is an integral part of drug policy in many countries. Similarly to other countries its introduction in the Czech Republic gave rise to a vibrant discussion. The aim of the study was to map and analyze pharmacists' opinions of, attitudes towards and experiences with generic drugs and GS after the first year from its legislative embodiment in the Czech Republic. All 7,665 members of the Czech Chamber of Pharmacists were addressed to participate in a questionnaire survey between November 2008 and March 2009. The questionnaire consisted of 28 questions concerning the issue of generic drugs and GS and was divided into five sections. All collected data were analyzed using descriptive statistics and correlations were tested by selected parametric and non-parametric tests. A total of 615 completed questionnaire forms were returned (a questionnaire return rate of 8.0%). The demographic characteristics of the respondents were as follows: 470 (76.4%) females, mean age of 37.5 years (SD = 10.4) and 429 (69.6%) pharmacists with a practice specialization. Altogether 345 (56.1%) respondents became aware of the issue of brand name and generic drugs during their undergraduate studies. 378 (61.5%) respondents considered generic drugs as bioequivalent and 455 (74.0%) respondents as therapeutically equivalent to the respective brand name drugs. 99 (16.1%) pharmacists believed that generic products are of lower quality than branded drugs and 69 (11.2%) respondents expected generics to cause more adverse drug reactions. GS was perceived as a positive tool by 476 (77.4%) respondents. Only 71 (11.5%) respondents showed acquaintance with all the legal rules for GS. Legislation awareness and attitude towards GS was correlated with age (p < 0.001). The use of GS in the routine practice depends on the pharmacists' familiarity with the relevant legislation and attitude towards generic drugs and GS. Approaching patients on an individual basis and pharmacists' awareness can minimize adverse drug events caused by generic drugs and at the same time enhance the professional status of pharmacists.

Retrospective analysis of gastrointestinal bleedings with direct oral anticoagulants reported to EudraVigilance.

Direct oral anticoagulants (DOACs) are increasingly used and are an important cornerstone in antithrombotic therapy. Adverse drug reactions (ADRs) such as bleedings have only partially been investigated during clinical trials. The primary goal was to analyse pharmacovigilance data based on spontaneous reports of gastrointestinal (GI) bleedings with DOACs reported to EudraVigilance. A second goal was to compare GI safety profiles between DOACs based on these signals. All DOAC related GI bleedings mentioned in individual case safety reports (ICSRs) from 2012 till 2017 in the European Economic Area were classified in four GI categories based on the reported site of occurrence of the haemorrhage. Age group and gender of the patient, seriousness and ADR outcome, and the reporter's qualification were assessed per category and per DOAC. Disproportionality analyses were performed to evaluate whether or not the reported ADRs were more prevalent with a given DOAC. ICSRs were bleeding-related in about half of the cases (n = 28,992/53,471). Of these bleedings, >25% was GI-related. Most patients experiencing GI bleedings were between 65 and 85 years old, with no obvious differences between men and women. Stomach, ulcer-related duodenal, and rectal bleedings were the most reported GI bleedings with a fatal outcome in 5.8%, 7.5%, and 9.8% of the cases for rivaroxaban, apixaban, and dabigatran, respectively. The disproportionality data suggest that dabigatran is more frequently involved in GI bleeding events than the other DOACs. DOACs were significantly associated with GI bleedings. Although the data should be interpreted with caution, it seems that dabigatran was associated more often than other DOACs with GI bleedings based on the analysis of spontaneous pharmacovigilance reports.

Self-reported medication administration errors in clinical practice of nurses: a descriptive correlation study.

BACKGROUND: Medication administration errors (MAE) are a worldwide issue affecting the safety of hospitalized patients. Through the early identification of potential causes, it is possible to increase the safety of medication administration (MA) in clinical nursing. The study aimed to identify potential risk factors affecting drug administration in inpatient wards in the Czech Republic. MATERIAL AND METHODS: A descriptive correlation study through a non-standardized questionnaire was used. Data were collected from September 29 to October 15, 2021, from nurses in the Czech Republic. For statistical analysis, the authors used SPSS vers. 28 (IBM Corp., Armonk, NY, USA). RESULTS: The research sample consisted of 1205 nurses. The authors found that there was a statistically significant relationship between nurse education (p = 0.05), interruptions, preparation of medicines outside the patient rooms (p < 0.001), inadequate patient identification (p < 0.01), large numbers of patients assigned per nurse (p < 0.001), use of team nursing care and administration of generic substitution and an MAE. CONCLUSIONS: The results of the study point to the weaknesses of medication administration in selected clinical departments in hospitals. The authors found that several factors, such as high patient ratio per nurse, lack of patient identification, and interruption during medication preparation of nurses, can increase the prevalence of MAE. Nurses who have completed MSc and PhD education have a lower incidence of MAE. More research is needed to identify other causes of medication administration errors. Improving the safety culture is the most critical challenge for today's healthcare industry. Education for nurses can be an effective way to reduce MAEs by enhancing their knowledge and skills, mainly focusing on increasing adherence to safe medication preparation and administration and a better understanding of medication pharmacodynamics.

Reasons for medication administration errors, barriers to reporting them and the number of reported medication administration errors from the perspective of nurses: A cross-sectional survey.

The aim of the study was to identify the reasons for medication administration errors, describe the barriers in their reporting and estimate the number of reported medication administration errors. BACKGROUND: Providing quality and safe healthcare is a key priority for all health systems. Medication administration error belongs to the more common mistakes committed in nursing practice. Prevention of medication administration errors must therefore be an integral part of nursing education. DESIGN: A descriptive and cross-sectional design was used for this study. METHODS: Sociological representative research was carried out using the standardized Medication Administration Error Survey. The research study involved 1205 nurses working in hospitals in the Czech Republic. Field surveys were carried out in September and October 2021. Descriptive statistics, Pearson's and Chi-square automatic interaction detection were used to analyze the data. The STROBE guideline was used. RESULTS: Among the most frequent causes of medication administration errors belong name (4.1 ± 1.4) and packaging similarity between different drugs (3.7 ± 1.4), the substitution of brand drugs by cheaper generics (3.6 ± 1.5), frequent interruptions during the preparation and administration of drugs (3.6 ± 1.5) and illegible medical records (3.5 ± 1.5). Not all medication administration errors are reported by nurses. The reasons for non-reporting of such errors include fear of being blamed for a decline in patient health (3.5 ± 1.5), fear of negative feelings from patients or family towards the nurse or legal liability (3.5 ± 1.6) and repressive responses by hospital management (3.3 ± 1.5). Most nurses (two-thirds) stated that less than 20 % of medication administration errors were reported. Older nurses reported statistically significantly fewer medication administration errors concerning non-intravenous drugs than younger nurses (p < 0.001). At the same time, nurses with more clinical experience (≥ 21 years) give significantly lower estimates of medication administration errors than nurses with less clinical practice (p < 0.001). CONCLUSION: Patient safety training should take place at all levels of nursing education. The standardized Medication Administration Error survey is useful for clinical practice managers. It allows for the identification of medication administration error causes and offers preventive and corrective measures that can be implemented. Measures to reduce medication administration errors include developing a non-punitive adverse event reporting system, introducing electronic prescriptions of medicines, involving clinical pharmacists in the pharmacotherapy process and providing nurses with regular comprehensive training.

[Analysis of pharmaceutical care in dispensing of over-the-counter orlistat]. / Analýza farmaceutické péce pri dispenzaci léciva orlistat v rezimu OTC.

Obesity is a chronic disease characterized by its high prevalence. Easy availability of pharmaceutical care allows pharmacies to be the first place of capture or intervention for patients who are overweight or obese. The aim of the study was to analyse the role of pharmacists and pharmacy technicians in securing the safety of self-medication with orlistat. In this prospective observational study, the patients were the people who came to the IKEM Hospital Pharmacy for self-medication with orlistat over a period of May through December 2009. The data were collected by trained pharmacists and pharmacy technicians in interviews with patients when dispensing over-the-counter (OTC) orlistat. The interview was designed by fixed questions. The results were analysed using frequency analysis, GLMz and the chi-square test with the level of significance of p < 0.05. A total of 50 patients participated in the study (44 women, median age 53 years, 41 patients with body mass index > 28). 58% patients were fully indicated for self-medication with orlistat. Self-medication with orlistat was recommended to 48% patients and was refused to 22% patients because of contraindications. 24% patients had at least one interaction with orlistat and chronic drugs. Health problems were the most common motivation for weight reduction. The data obtained in this study demonstrate an important role of pharmacists and pharmacy technicians in the assessment of suitability of self-medication with OTC orlistat and safe weight reduction within self-medication.

Comparison of different methods to assess tacrolimus concentration intra-patient variability as potential marker of medication non-adherence.

Background and objective: Non-adherence to tacrolimus commonly manifests as low drug concentrations and/or high intra-patient variability (IPV) of concentrations across multiple measurements. We aimed to compare several methods of tacrolimus IPV calculation and evaluate how well each reflects blood concentration variation due to medication non-adherence in kidney transplant recipients. Methods: This Czech single-center retrospective longitudinal study was conducted in 2019. All outpatients ≥18 years of age, ≥3 months post-transplant, and on tacrolimus-based regimens were approached. After collecting seven consecutive tacrolimus concentrations we asked participating patients to self-report adherence to immunosuppressants (BAASIS© scale). The IPV of tacrolimus was calculated as the medication level variability index (MLVI), the coefficient of variation (CV), the time-weighted CV, and via nonlinearly modeled dose-corrected trough levels. These patient-level variables were analyzed using regression analysis. Detected nonlinearities in the dose-response curve were controlled for by adding tacrolimus dosing and its higher-order terms as covariates, along with self-reported medication adherence levels. Results: Of 243 patients using tacrolimus, 42% (n = 102) reported medication non-adherence. Non-adherence was associated with higher CVs, higher time-weighted CVs, and lower dose-corrected nonlinearly modeled trough levels; however, it was not associated with MLVIs. All of the significant operationalizations suggested a weak association that was similar across the applied methods. Discussion and conclusion: Implementation non-adherence was reflected by higher CV or time-weighted CV and by lower blood concentrations of tacrolimus. As an additional tool for identifying patients at risk for non-adherence, simple IPV calculations incorporated into medical records should be considered in everyday clinical practice.

Self-Reported Overall Adherence and Correct Inhalation Technique Discordance in Chronic Obstructive Pulmonary Disease Population.

Background: Adherence to inhaled medication constitutes a major problem in patients with chronic obstructive pulmonary disease (COPD) globally. However, large studies evaluating adherence in its entirety and capturing a large variety of potentially associated factors are still lacking. Objective: To study both elementary types of adherence to chronic inhaled COPD medication in "real-life" COPD patients and to assess relationships with a wide-ranging spectrum of clinical parameters. Methods: Data from the Czech Multicentre Research Database (CMRD) of COPD, an observational prospective study, were used. Overall adherence (OA) was evaluated with Morisky Medication Adherence Scale (©MMAS-4) and adherence to an application technique (A-ApplT) with the Five Steps Assessment. Mann-Whitney U test, Spearman's correlation, and logistic regression were used to explore relationships between variables. Results: Data of 546 participants (69.6% of all patients from the CMRD) were analyzed. Two-thirds self-reported optimal OA, but only less than one-third demonstrated A-ApplT without any error. OA did not correlate with A-ApplT. Next, better OA was associated with higher education, a higher number of inhalers, a lower rate of exacerbations, poorer lung function, higher degree of upper respiratory tract symptoms (SNOT-22), absence of depressive symptoms, ex-smoking status, regular mouthwash after inhaled corticosteroids (ICS), and flu vaccination. By contrast, better A-ApplT was associated with a lower number of inhalers, better lung function, and regular mouthwash after ICS. Independent predictors of nonoptimal OA included lower degree of education, absence of flu vaccination, anemia, depression, and peptic ulcer history, whereas independent predictors of lower A-ApplT were lower education, absence of regular mouthwash after ICS, and higher COPD Assessment Test score. Conclusions: Parameters associated with OA and A-ApplT differ, and those associated with both adherence domains are sometimes associated inversely. Based on this finding, we understand these as two separate constructs with an overlap.

Inflammatory blood parameters as prognostic factors for surgical site infection after primary hip or knee arthroplasty: a systematic review protocol.

INTRODUCTION: Surgical site infection (SSI) is a potential complication of surgical procedure. SSI after implant surgery is a disaster both for patients and surgeons. Although predictive tools for SSI are available, none of them estimate early infection based on inflammatory blood parameters. The inflammatory process can be measured using several parameters including interleukin-6, C reactive protein, neutrophil to lymphocyte ratio, white cell count, erythrocyte sedimentation rate or procalcitonin. This systematic review aims to determine whether inflammatory blood parameters could be used as significant predictive factors for SSI after primary hip or knee arthroplasty. METHODS AND ANALYSIS: A systematic review of randomised controlled trials, cross-sectional studies, case-control studies and cohort studies, published in English, will be searched in the following electronic bibliographic databases: MEDLINE, Embase, PubMed, Cochrane Central Register of Controlled Trials and Web of Science. Studies performed in adult patients of all ages who underwent knee or hip arthroplasty, studies containing data on the risk/prognostic factors for preknee or postknee or hip arthroplasty SSI and studies with a minimum follow-up of 30 days after surgery will be included. A standardised form will be used to extract data from the included studies comprising study characteristics, participant characteristics, details of the intervention, study methodology and outcomes. Quality Assessment of Diagnostic Accuracy tool, second version, and Standards for Reporting of Diagnostic Accuracy Studies checklist will be used to assess risk of bias. Heterogeneity will be assessed using Cochran χ² statistic and I2 statistics where applicable. Grading of Recommendations Assessment, Development and Evaluation and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance will be used to report findings. ETHICS AND DISSEMINATION: No ethics approval is required. The findings will be disseminated at national and international scientific sessions, also to be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42020147925.

Changes in Beliefs About Post-Transplant Immunosuppressants Over Time and Its Relation to Medication Adherence and Kidney Graft Dysfunction: A Follow-Up Study.

PURPOSE: The main aim was to evaluate the changes in beliefs about immunosuppressants over a 3-year period in patients after kidney transplantation. The second aim was to investigate the relationship between beliefs, medication adherence, and selected clinical outcomes such as graft functioning. PATIENTS AND METHODS: This observational follow-up study was conducted in the outpatient post-transplant clinic at the University Hospital Hradec Kralove in the Czech Republic. Adult patients, at least 4 weeks after kidney transplantation, were invited for the structured interview, which was followed by a self-administered questionnaire survey during their regularly scheduled visits at the clinic. Appropriate paired tests were used to compare two measurements of beliefs about immunosuppressants by BMQ-CZ© in 2016 (baseline) and in 2019 (follow-up). Self-reported adherence was measured by two validated tools (MARS-CZ© and BAASIS©) capturing implementation and discontinuation phases. A generalized linear model was used to investigate the relation between beliefs and the consecutive estimated glomerular filtration rate. RESULTS: The study involved 134 patients. Over time, their perceived treatment necessity beliefs of immunosuppressants decreased, while their treatment-related concerns increased. Overall self-reported non-adherence (ie, taking, dosing and discontinuation of immunosuppressants) was reported by 12% of the patients in both observation periods. In the follow-up period, timing non-adherence was reported by 52 (38.8%) patients. Higher baseline treatment concerns were associated with poor adherence whereas higher baseline treatment necessity beliefs corresponded with better kidney functioning, even after adjusting for age. CONCLUSION: Higher treatment necessity beliefs corresponded with better kidney functioning, whereas higher treatment concerns were related to non-adherence to immunosuppressants at the beginning of the observed period. Still, most patients accepted their medicines that do not come without risk. Nevertheless, decreasing treatment necessity beliefs on one hand, and increasing treatment concerns on the other, should be considered in clinical practice.
