Effectiveness of Fall Prevention Intervention Programmes in Nursing Practice
HOROVÁ, Jana
Patient falls and fall injuries have become one of the most common adverse events reported by health care providers due to all the circumstances associated with hospitalisation.Worldwide preventive actions in the field of patient falls focus on soft factors,predominantly on the education of healthcare professionals and patients,and organisational culture.Due to the dynamic development of information technologies and the increasing digital literacy of the professional and lay population,the e-learning field is an increasingly sought-after form of education.The empirical part's main objective was to determine the effectiveness of general nurses' education through information technology as an intervention programme to prevent patient falls. The main objective was divided into consecutive partial objectives.A mixed approach was used.The study uses a observational-interventional design. The first partial objective,an analysis of patient falls, was investigated using a quantitative research method.Patient falls concerning a major health care provider were analysed over five years.The ??2-test or Fisher's exact test was used to test statistical relations.The Kruskal-Wallis test was used to test nonparametric variables.Regression analysis was applied to evaluate the trend in the incidence of fall injuries with regard to high-risk patients.The second research phase was based on the previous phase results,whereby a qualitative methodological approach was selected.The aim was to detect areas of falls focused on the specifics of the clinical environment,which were suitable for being included in the educational programme.Data was collected through a semi-structured interview. The third partial objective was creating and implementing an e-learning educational programme for general nurses in a clinical environment.Within the pilot testing,the properties of knowledge tests,content validity,and reliability were verified using Spearman's rank correlation coefficient and Cronbach's alpha.The effectiveness of the established e-learning programme (fourth partial objective)was verified by comparing the incidence of patient falls before and after the established intervention.Bonferroni correction and test of equality of parameters of two alternative distributions were used to verify the homogeneity of the compared groups of patients. With regard to the possible influence of confounders and to verify the incidence of injuries caused by falls,the method of statistical matching (propensity score matching) was subsequently used.Valuation of the e-learning programme's effectiveness with regard to the participants' level of knowledge was performed by comparing the results of the input and output knowledge test,for which the Stuart-Maxwell test and Fisher's exact test were used.The analysis of partial objectives of individual research phases was carried out separately;the objectives logically followed,and fulfilling the previous objective conditioned their fulfilment.The test of equality of parameters of two alternative distributions allowed for comparing groups of patients that could be considered equal.There was a decrease in the incidence of patient injuries due to falls in both disciplines (all injuries in the surgical discipline; p ? 0.05 and severe injuries in the internal medicine discipline; p ? 0.01).The results proved the influence of the e-learning educational programme on specific clinical practice indicators.Statistical matching eliminated confounding factors and confirmed a statistically significant reduction in the incidence of falls in patients with internal medicine injuries (p? 0,05).There was also an improvement in the participants' knowledge in the output knowledge test (p ? 0,001). Education of medical personnel based on the principles of science and the needs of clinical practice is a possible effective preventive intervention in patients falls and efforts to minimise the occurrence their consequences.

Falls in Geriatric Patients at the Follow-up Care Department
CARDOVÁ, Lenka
This diploma thesis is dedicated to falls in geriatric patients in the aftercare department. Thesis Objectives: To carry out a complex analysis of multifactorial causes in chosen cases of geriatric patients that occured during hospitalization in a chosen aftercare workplace from 2020 through 2021 in Nemocnice České Budějovice, a.s. To carry out SWOT analysis of a chosen aftercare workplace in Nemocnice České Budějovice, a.s. with the objective to evaluate interventions used in preventing falls of patients hospitalized in the given workplace. Suggestion of recommendation to improve current practice of the chosen aftercare workplace in Nemocnice České Budějovice, a.s. in preventing falls in hospitalized patients. Methodology and Research File: To reach the objectives, three research questions were chosen. What are multifactorial causes of chosen cases of falls in geriatric patients in the chosen aftercare workplace? What interventions are used to prevent falls in geriatric patients in the chosen aftercare workplace? What interventions might improve current practice in preventing falls in hospitalized geriatric patients in the chosen aftercare workplace? To implement a survey, a qualitative research strategy was chosen. For case study purposes, the following data collection techniques were used - medical documentation content analysis, reporting adverse events, controlled documentation etc., semi-structured interviews with doctors in specific fall cases. In the following part of the survey, where we were finding out about the intervention used and intervention meant for improving the current practice in fall prevention, semi-structured interviews were carried out with doctors and nurses. Interviews with the nurses were completed by participant observations. Based on the survey results, a SWOT analysis was processed. The research file consisted of 14 chosen falls that happened in hospitalized geriatric patients in the aftercare department from 2020 through 2021, of 12 nurses working in the aftercare department, of 9 doctors that were informed of a fall. A deliberate choice of both nurses and doctros was used, the criterium for being included in the research file was the minimum of a year-long practice in the aftercare deparment. The obtained data was processed using the pen-and-paper method, open coding, and data was subsequently categorized and noted down into tables and schemes. Results: Complex analysis of multifactorial causes of chosen fall cases proved that falls happened due to internal as well as external factors. The risk of a fall was increased by the pateints´ age, morbidity, polypharmacotherapy, cognitive deficit, sarcopenia, fragility syndrome, instability, bed siderails lifted, and human resource failure. Based on the results, we carried out SWOT analysis and we suggested a recommendation to improve the current practice in the chosen aftercare workplace. Practice Recommendations: Based on the survey, we would recommend for a repetitive evaluation of the risk of patients falling to be carrried out. Another recommendation would be educating the nursing staff in the area of fall prevention, in the area of communicating with geriatric patients and patients suffering from dementia. Further on, we would recommend ensuring the use of suitable positioning aids and securing a movement-detection system inside the bed. Last but not least, we would recommend increasing numbers of nursing staff.

The possibilities of physiotherapy which improve the postural stability of seniors
NOVOTNÝ, Petr
These days, due to low natality and increasing life expectancy, we face the fact that the Czech population is getting older and older. Growing old is connected with risks of health difficulties, that have a huge impact on the quality of our lives. One of the most important health problems that elderly people have is instability causing e.g. falls. They are quite common with increasing age and they can cause lots of serious consequences. Seniors with provable symptoms should not underestimate their state of health and they should rather look up specialized care. One of the options for the prevention of impaired postural stability and subsequent falls may be physiotherapy that focuses on this issue. This diploma thesis aims to describe the possibilities of how physiotherapy can help improve postural stability with elderly people. The thesis also suggests exercises that seniors could do on their own and thanks to them elderly people could improve their postural stability. My diploma thesis consists of the theoretical and practical part. The first one contains gained pieces of knowledge of later life, growing old, postural stability, and application of physiotherapy. In the practical part, I mention six case interpretations with elderly people between 76 and 78 years. In these interpretations, which consisted of entrance and final tests, we can see the differences that appeared after stabilographic training and after following the method that I had created. I believe that this thesis could help spread awareness of impaired postural stability with elderly people. It could probably be used for the training of seniors and it could become a therapeutic methodology not just for nurses in the retirement homes but probably for the general public as well.
