The Geographical Distribution of Morbidity Caused By Chronic Obstructive Pulmonary Disease in Turkey: COPDTURKEY-2

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is one of the most prevalent causes for morbidity and mortality, and it creates a cumulative economic and social burden. AIMS: To determine the distribution of the prevalence of patients in Turkey who were diagnosed with COPD and their morbidity rates, according to the regions and cities they belong to. Moreover, the study contributes to the prevention and cure services of COPD that should be planned in the future. STUDY DESIGN: A retrospective cohort. METHODS: The database of the Social Security Institution from 2016 has been scanned. All the data with prescription registration, with the code ICD-10, J44.0-J44.9, which were aimed for diagnosing and/or cure, have been evaluated with a retrospective cohort. RESULTS: In 2016, 955,369 patients who were admitted as outpatients to the hospitals were diagnosed with COPD. The average number of annual COPD cases that were admitted was 2.09. Twenty percent (20%) of the outpatient applications were via emergency room. The rate of hospitalization among the applicants was 17.75%, with a total of 1,994,325. The average annual number of hospitalizations of men was higher than that of women. The average number of hospitalization days was 6.52. The region with the highest prevalence of outpatient admission and hospitalization was the Black Sea Region. CONCLUSION: The high rate of hospitalization was considered to be the outcome of the insufficient “outpatient” management.
