A National Registry-Based Epidemiological Study to Evaluate 395 646 Patients Hospitalized Due to Eye Diseases in Poland in 2019.

BACKGROUND The Nationwide General Hospital Morbidity Study Registry collects demographic, health, and medical data on patients hospitalized throughout Poland, and acts as a registry for epidemiological, public health, and hospital administrative studies. This epidemiological national registry-based study aimed to evaluate the characteristics of 395 646 patients hospitalized due to eye diseases in Poland in 2019. MATERIAL AND METHODS This study is a retrospective nationwide registry-based analysis. Data on all patients hospitalized due to eye diseases in 2019 were obtained from the Nationwide General Hospital Morbidity Study Registry. Demographic characteristics of patients hospitalized due to eye diseases as well as the hospitalization course were analyzed using descriptive epidemiology tools. RESULTS Disorders of the lens accounted for 68.6% of all hospital admissions, and disorders of the choroid and retina were the second most common (13.9%) cause of hospital admission due to eye diseases in 2019. Over three-quarters of hospital admissions (77.4%) lasted less than 24 h, and 86.8% were scheduled admissions. Most of the patients hospitalized due to eye diseases were females (59.9%) and over 70% lived in urban areas. There were regional differences in the hospital admissions rate per 100 000 inhabitants. According to the data presented in the registry, less than one-third of patients had comorbidities. CONCLUSIONS Hospital ophthalmological care in Poland is based mainly on planned hospitalizations lasting less than 24 h and related to ophthalmological surgery. Data on the comorbidity of ophthalmologic patients suggest that ophthalmologists do not pay enough attention to identifying and recording the patient's health status.
