Based on the provided data, the healthcare expenditure on specialised outpatient curative care in the Netherlands is forecasted to slightly decrease from 13.35% of total current health expenditure in 2024 to 13.23% by 2028. This represents a gradual decline year-on-year. Hence, the average variation per year over the next five years (CAGR) indicates a minor negative trend. Starting from 2024, the year-on-year changes display a steady and minimal reduction in the expenditure share.

Future trends to watch for include:

Technological advancements and their impact on outpatient care efficiency and cost reduction.
Policy changes and reforms in healthcare funding and allocation within the Netherlands.
The effect of an aging population on healthcare demands and expenditure.
Potential shifts towards preventative care which may influence budget allocations differently.
