Mortality Rate in Stroke patients treated at the Clinic of Neurology, Clinical Hospital Split, in the period 2009-2013

Cilj: Cilj predloženog istraživanja je utvrditi smrtnost od moždanog udara u populaciji bolesnika liječenih u Klinici za neurologiju KBC Split tijekom razdoblja od 2009. – 2013. godine. Metode: Kao osnovni izvor podataka korištene su povijesti bolesti i otpusna pisma iz ispitivanog razdoblja. Izdvojene su povijesti bolesti s dijagnozom I60–I69 prema MKB-u (cerebrovaskularne bolesti). Ispitanici su podijeljeni u dvije grupe po dijagnostičkim podskupinama: MKB I60-I62 (bolesnici s krvarećim moždanim udarom) i MKB I63-I69 (bolesnici s ishemijskim moždanim udarom). Uvidom u povijesti bolesti tih ispitanika te temeljem otpusnih pisama izdvojeni su bolesnici koji su umrli od posljedica moždanog udara. Iz povijesti bolesti prikupljeni su i podaci o dobi, spolu i dužini liječenja ispitanika. Retrospektivna analiza podataka vršena je u razdoblju od svibnja do lipnja 2014. godine. Rezultati: U razdoblju od 2009.godine do 2013. godine ukupno je liječeno 5845 bolesnika s dijagnozom cerebrovaskularne bolesti. Broj muškaraca iznosio je 2951 (50,5% od ukupnog broja), dok je broj žena iznosio 2894 (49,5% od ukupnog broja). Prosječna životna dob iznosila je 74 godine, 71,3 godine za muškarce, a 75,6 godina za žene. Od ukupnog broja liječenih preživjelo je 4734 bolesnika (81%), dok je smrtni ishod zabilježen za 1111 bolesnika (19%). Ukupan udio bolesnika umrlih od krvarećeg moždanog udara iznosio je prosječno 20,4%, a bolesnika umrlih od ishemijskog moždanog udara prosječno 79,6% od ukupnog broja umrlih. Prosječna dob umrlih po ispitivanim godinama iznosila je 79 godina, s tim da je za muškarce iznosila 77, a za žene 80 godina. Prosječna dužina liječenja bolesnika tijekom ispitivanih godina iznosila je 9,1 dan. Prosječna dužina liječenja preživjelih bolesnika iznosila je 9,7, a umrlih 6,5 dana. Statistički nije utvrđena značajna razlika u broju bolesnika umrlih od moždanog udara po godinama tijekom ispitivanog razdoblja, kao ni statistički značajna razlika u broju bolesnika umrlih od moždanog udara prema dijagnostičkim podskupinama tijekom ispitivanog razdoblja. Zaključak: Rezultati provedenog istraživanja potvrdili su polaznu hipotezu da ne postoji značajna razlika u godišnjoj učestalosti smrtnog ishoda za bolesnike s moždanim udarom liječene u Klinici za neurologiju KBC Split tijekom promatranog razdoblja (2009-2013. godina).Goal: The goal of the submitted research is to determine the mortality within the population of stroke victims that were treated at the Neurologic Clinic of the Clinical Hospital Center Split during the period from 2009 to 2013. Methods: As the main source of data medical records and hospital release forms from the period of research have been used. The medical records with a diagnosis 160-169 according to ICD (cerebrovascular diseases) were singled out. The respondents were divided into two groups according to diagnostic subgroups: ICD I60-I62 (the hemorrhagic stroke patients) and ICD I63-I69 (the ischemic stroke patients). Examining the medical records of the respondents and on the basis of their hospital release forms, those patients who died due to the effects of stroke (or brain attack) were differentiated. From the medical records, the data on age, sex and medical treatment period of the respondents was gathered. The retrospective data analysis was carried out from May to June of the year 2014. Results: During the period from 2009 to 2013, a total of 5845 patients with the cerebrovascular disease diagnose were treated. The number of male patients was 2951 (a 50,5% of the total number), while the number of women was 2894 (a 49,5% of the total number). The average age of the patients was 74, or more specifically, 71, 3 for men and 75, 6 for women. Out of the total number of patients treated, 4734 patients survived (an 81%), while the amount of fatal outcomes registered was 1111 (a 19%). The overall percentage of patients who died of hemorrhagic stroke was 20,4%, while there were averagely 79,6% patients out of the total number of deceased, who died of ischemic stroke. The average age of the deceased in the research period was 79, whereas it was 77 for men, and 80 for women. The average treatment period for the survived patients was 9,7 days and for the deceased it amounted to 6,5 days. Statistically, neither a relevant disparity in the number of patients deceased as a consequence of stroke, during the years of the research period, was encountered, nor was there registered a statistically relevant disparity in the number of patients deceased, from both diagnostic subgroups, during the period of this research. Conclusion: The results of the executed research have confirmed the starting hypothesis that there is no significant discrepancy in the annual frequency of fatal outcome for the stroke patients treated at the Neurologic Clinic of the Clinical Hospital Center Split during the contemplated period (2009-2013)
