Nursing Care in Patients with MRSA
Zajacová, Aneta ; Trojánek, Milan (advisor) ; Jirkovský, Daniel (referee)
The bachelor thesis "Nursing Care in Patients with MRSA" deals with the issue of barrier regimen in the context primarily with golden staphylococcus infection. The aim is to assess the attitudes of nursing staff about nursing care in patients with MRSA, analyze the adherence to contact precautions in the clinical practice and to identify the factors associated with potential non-adherence. The theoretical part of the thesis serves as an introduction to the topic, while the empirical part contains the results of the actual investigation and serves to explore the above objectives. The research method was a self-constructed questionnaire with 33 questions, which was distrubuted among the nursing staff in the surgical and internal inpatient wards of the adult part of Motol University Hospital. Responses from 67 respondents were included and the obtained data were statistically processed. The survey resulted in the following findings: Only 13 respondents (19 %) say that everyone on their ward always adheres to barrier measures. The most common situation where barrier measures are not adhered to is 'acute patient condition' with 27 respondents (40 %) and 'at night' with 12 respondents from the standard ward and only 1 from the ICU. The motivation for more consistent adherence to barrier measures is fear...

Monitoring and detection of Escherichia coli and Klebsiella pneumoniae strains with Extended Spectrum Beta-Lactamase (ESBL) production in Hospital Prachatice, a. s. in 2014-2018.
TVRDKOVÁ, Pavla
The ever increasing resistance of bacteria is a grave issue world-wide. Some bacteria are resistant naturally but for other resistance is acquired. As a result, we can encounter bacterium that would formerly be quite easily killed by administering antibiotics but, in the course of time, as a result of, for example, communication between various bacteria species and strains in the form of various mutations and, frequently, after the administration of incorrect antibiotic and the effects of selective antibiotic pressure, the same bacterium becomes resistant to antibiotics. One of the types of such acquired resistance is the production of broad-spectrum beta-lactamases ESBL. The objective of this thesis is to establish the representation and development of ESBL production in Escherichia coli strains and Klebsiella pneumoniae strains as these make the most frequent producers of these broad-spectrum beta-lactamases, in certain hospital departments and in various types of clinical materials over the period of 5 years. In addition, the thesis focuses on the development of antibiotic resistance, accordingly, over the 5 year period. Data gathering and utilization of methods took place at the Medical Microbiology Department of the Prachatice Hospital (Nemocnice Prachatice, a.s.). To identify microbes to a more precise level, the commercial set ENTEROtest 24 N and INDOL test were used. The disk diffusion method and method for determining the minimum inhibitory concentration were used to determine sensitivity to antimicrobial agents. The commercial set MASTDISC AmpC and ESBL (D68C) were used to detect ESBL. The outcomes indicated that the number of Escherichia coli strains producing ESBL and Klebsiella pneumoniae strains producing ESBL grew almost each year (with the exception of 2016). The outcomes also indicated that the greatest number of ESBL producers were found with Klebsiella pneumoniae strains. Furthermore, the ESBL producers were grouped depending on hospital departments in which most frequent occurrences were found; the most frequent ESBL occurrence of both producers was found in the department of internal medicine. Additionally, the ESBL producers were grouped based on capture in various types of clinical materials; the greatest quantities of both microbes were found in urine. Based on these findings, the development of antibiotic resistance for both microbes over the period of 5 years was analyzed on samples of urine. When monitoring antibiotic resistance development, no considerable growths in bacterial strains resistant to individual anti-microbial agents was found over the 5 year period. Only for 3rd generation cephalosporins, there was a certain growth in resistance detected almost every year for both microbes. Namely, Escherichia coli isolates showed a growth from 6 % to 9 % and Klebsiella pneumoniae isolates showed a growth from 29 % to 33 % in the percentual quantity of strains resistant to these antibiotics.

Occurrence of ESBL strains in Hospital Pisek, Inc.
KOTHÁNKOVÁ, Michaela
Resistance to ATB is becoming a big problem all round the world. Bacterial resistance occurs naturally or is obtained by gene mutations where genetic information is transmitted between genera or species. These strains are then resistant to antibiotics that are otherwise effective. The biggest problem is that in these cases the treatment is prolonged, the mortality and morbidity of the patients increases and the costs of the treatment as well. The initial theoretical part is devoted to the characteristics and types of effects of antimicrobial agents, beta-lactam antibiotics, antibiotic resistence, where resistance transfer process, multiresistance and resistance mechanisms are described. Further, this part is dedicated to beta-lactamases and their classification, broad-spectrum beta-lactamases (ESBL) and their producers, especially the genus Klebsiella, the genus Escherichia, the genus Enterobacter and the genus Proteus. The last chapter of this part is focused on the impact of resistance to therapy and treatment options. A methodical part of this work was performed at the Department of Clinical Microbiology of Písek Hospital, Inc., where the detection of ESBL positive strains of the genus Klebsiella, Escherichia, Enterobacter and Proteus was observed during one year (January-December 2016). This part focuses on microbes of the mentioned genera and their antibiotic susceptibility. For susceptibility testing, this is a disk diffusion test based on the inhibition zone and a bouillon microdilution method, which is based on minimum inhibitory concentration. Further, this part also deals with an ESBL production test where a screening test using Brilliance ESBL agar chromogenic soil and method of detection ESBL and AmpC production (known as the MAST test) are described. The last chapter of this part is dedicated to quality control. In the practical part of the thesis, we can compare the incidence of bacteria genus Klebsiella, genus Escherichia, genus Enterobacter, genus Proteus and their production of ESBL. Further, this part is focused on the distribution of isolates with ESBL production according to the type of hospital department, the highest incidence was found in the department of aftercare and department of social beds. This section also describes the distribution of ESBL-producing isolates according to the type of clinical material, where there was a huge catch in the urine. It was also compared the number of ESBL producers in the hospital and the community where it was found 85% incidence in the hospital, which was expected.

Detection of extended-spectrum beta-lactamase (ESBL) producers in community and in a hospital
POLENOVÁ, Lucie
The incidence of bacteria resistant to available antibiotics has become an important problem. Statistics show the rising number of resistant bacteria worldwide. Bacteria have ability to be resistant naturally or they develop from point mutation of genes and relay it between species or kinds. The study was made because of significance and relevance of this problem. In theoretical part the study is focused on the functional parts of bacterial cell, which participate in mechanisms of resistance. Beta - lactam antibiotics are described in more detail. The research took place in Hospital České Budějovice, a. s. during 2013. The study aimed to determine the frequency of ESBL positive producers in this hospital and to compare with frequency in community, and to identify units with highest frequency of ESBL producers. Pathogens are isolated from clinical material, being delivered to bacteriology lab in Hospital České Budějovice, a. s. Resistant samples were examined with double disc synergy test (DDST) and quantitative method based on principle of minimal inhibition concentration in combination with chromogenic agar. The prevalence rate of ESBL producers is average to low in Hospital České Budějovice, a. s. During 2013, 12, 347 isolates were identified, ESBL production was identified in 226 isolates. Escherichia coli (183 isolates), Klebsiella pneumoniae (16 isolates), and Enterobacter cloacae (15 isolates) were the most prevalent species. The number of ESBL producers was lower compared to 2012, 2011, and 2010.

Nursing care of a patient with multi-resistant strains
ZAJÍCOVÁ, Lucie
Occurrence of bacterial resistance appeared already five years after the antibiotics had been introduced in practice. Currently the occurrence of resistant or multiresistant strains is increasing. It is therefore highly important to adhere to barrier nursing techniques for clients colonized or infected with multiresistant strains. The risk of transmission of infection between patients and also between the medical staff is thus minimized. However, many of the nursing staff have not fully realized the importance of adhering to the barrier nursing care. A quantitative research by means of anonymous questionnaires was applied to collect the data. The research survey was carried out in the specialized departments of Nemocnice České Budějovice a.s. (The Hospital of České Budějovice). The following information was checked: identification data, the awareness of the nursing staff concerning the barrier care and the possibilities of the nursing staff to adhere to this care in practice when nursing clients suffering from multiresistant strains. 139 questionnaires have been distributed from which 110 (100%) have been included in the research. In the bachelor thesis the awareness of the nursing staff concerning the barrier nursing care and the possibility to adhere effectively to this kind of care for nursing clients suffering from multiresistant strains has been investigated, which was also stated in the aims of the paper (there were three of them), which were confirmed by the results of the research. Three hypotheses were set. The first one was to prove that the nursing staff adhere to the barrier nursing care for patients suffering from multiresistant strains, which was confirmed. The second one was to prove, that the nursing staff have enough aids to adhere to barrier care for patients suffering from multiresistant strains. This hypothesis was also confirmed. The third one was to prove that the nursing staff are acquainted with principles of barrier nursing technique as prevention of transmission of multiresistant strains, which was also confirmed. In general it can be stated that although the nursing staff are over strained in their work physically and psychically due to evident lack of nursing staff in all departments, the awareness and adherence to barrier nursing care and thus the minimizing the risk of transmission of resistant or multiresistant strains is evident. The research has shown that in spite of problems the nursing staff is to handle daily, the adherence to barrier nursing technique is important for them. The awareness in this field is on a very satisfactory level, as well as material equipment and aids necessary to adherence to barrier care. There is also a tendency from the part of the superiors to inform on topical subjects in nursing care for clients suffering from multiresitant strains in regular seminars organized within the hospital. The adherence to barrier nursing care is an essential part of care for clients suffering from multiresistant strains. The results of the paper shall be used to inform medical staff on this issue to make a positive impact on opinions of medical staff on adhering to barrier nursing care to prevent transmission of multiresistant strains.
