Cieľ: V práci sme sa zamerali na vedomosti pacientov s astmou v oblastiach self-manažmentu tohto ochorenia a najmä na vplyv faktoru dĺžky trvania tohto ochorenia na úroveň vedomostí o self-manažmente. Zároveň sme zisťovali vzťah medzi úrovňou vedomostí o self-manažmente ochorenia a kontrolou astmy. Metodika: V tejto prierezovej štúdii bolo do súboru zaradených 297 respondentov. Na testovanie kontroly astmy a úrovne vedomostí pacientov sme použili valídne nástroje a to Dotazník vedomostí o self-manažmente astmy pre dospelých (Measuring asthma self-management knowledge in adults) a Test kontroly astmy (Astma Control Test ACTTM). Na štatistické spracovanie dát boli využité: Pearsonov Chi-kvadrat test nezávislosti a Spearmanov korelačný koeficient. Výsledky: Až 220 z 297 respondentov (74,07 %) preukázalo nedostatočné vedomosti, a to konkrétne v doméne Vedomosti o liečbe astmy. V oblasti Manažment bronchiálnej astmy malo nedostatočné vedomosti 191 respondentov (64,31 %). Početnosť správnych odpovedí zároveň naznačuje, že úroveň vedomostí v doménach self-manažmentu astmy, významných pre kontrolu ochorenia, bola vyššia v skupine pacientov diagnostikovaných v priemere jeden rok ako v skupine, ktorá trpí ochorením dlhšie (6-10 rokov), i keď rozdiel nie je štatisticky významný. Záver: Nedostatky vo vedomostiach astmatikov, vyššia frekvencia chýb v oblastiach self-manažmentu, vrátane self-monitoringu a horšia kontrola astmy pri ochorení diagnostikovanom viac ako 6 rokov naznačujú, že je potrebné v klinickej praxi venovať čas a pozornosť reedukácii, opakovanému posúdeniu vedomostí a praktických zručností (aplikácia metód self-manažmentu, inhalačnej techniky) v skupine už skôr diagnostikovaných astmatikov., Aim: This project is aimed to find out the patient knowledge with asthma in the area of self-management of this disease and particularly the influence of the length of the disease on the knowledge level about self-management. At the same time we tried to find out the relation between the knowledge level of the asthma self-management and control of asthma disease. Methods: The total number of 297 adult asthma patients were included in the cross sectional study. The valid instruments Asthma Control Test and Measuring asthma self management knowledge in adults were used for testing asthma control and the degree of patient knowledge in self management of asthma. The Chi-squared test and the Spearman´s rank correlation coefficient were used for statistical processing of data. Results: A total of 220 out of 279 respondents (74%) showed poor knowledge of selfmanagement of asthma, particularly in “Knowledge of asthma treatment” domain and 191 patients in “Management of bronchial asthma” domain (64%). Patients who had been diagnosed one year ago had better level of knowledge in selfmanagement of asthma than those who had been treated for asthma longer than six years (6-10 years). This difference was not significant, but it was related to those domains which has significant influence on asthma control (domains 2-5). Conclusion: Poor knowledge of asthma patients, higher frequency of errors in self management and worse control of asthma in patients with asthma longer than six years imply the need for better and repeated education, check of patient knowledge and skills for self-management, use of peak flow meter included in this group of patients., Michaela Dingová, Petronela Osacká, and Literatura
