Number of patients per 1,000 inhabitants, 50 years and older
The number of patients in treatment increased by approximately 1,300 per year from 2015 to 2023, from 11,043 patients in 2015 to 21,911 patients in 2023. The reason for the patient growth is that this is a treatment for chronic conditions like age-related macular degeneration, and that the number of new patients each year exceeds the number of patients who discontinue their treatment. If the number of patients in treatment continues to increase in the coming years, changes in the organization of services may be needed to ensure access to good and equitable treatment.
Most of the patients were between 70 and 90 years old. The rate for women was 11,7 pastients pr 1 000 women and the rate for men was 9,5 patiens pr 1 000 men in 2023. There is significant geographical variation in the patient rate. This is in agreement with Husum et al. 2023, who suggest that the observed variation may be related to overtreatment in some areas and undertreatment in others. The authors point to a need for clearer management, national guidelines, and a national quality register in the field.
The analysis is based on activity data from the Norwegian Patient Register (NPR) for somatic specialist health services. The data includes activity in public hospitals and private hospitals that provide publicly funded services. Data from specialists under public funding contracts are not included, as this treatment is only provided in hospitals.
The sample consists of patients aged 50 years or older registered with a primary or secondary diagnosis of age-related macular degeneration, AMD (H35.3), venous occlusion (H34.8 or H34.9), or diabetic retinopathy (H36.0, E10.3, or E11.3) in combination with procedure code CKD05.
If the patient has moved between two catchment areas within a year, the residence is defined as the residence/catchment area where the patient had the most contacts during the year.
In order to compare the catchment areas and between years, the rates have been adjusted for gender and age. The adjustment was done using the direct method with the population in 2023 as the reference population.
