BACKGROUND:
Public health systems are deeply shaped by governance structures, political decisions, and economic reforms. In Latin America, institutional transformations have had lasting effects on the organization and delivery of health services. This study examines the Chilean case to explore how health system reforms have influenced hospital service provision over time, offering insights into the intersection of public health, governance, politics, and economics.

METHODS:
A longitudinal analysis was conducted using official data sources and institutional records to construct a time series of hospital discharges. Key indicators included total discharges, discharge rates per population, and comparative metrics. The study employed exploratory visualizations and segmented regression models to identify patterns associated with major institutional reforms.

RESULTS:
Findings reveal sustained growth in hospital discharges, with notable periods of private sector expansion. Public hospital service provision showed signs of stagnation or decline following specific reforms, highlighting the contrasting trajectories of different health system models. These shifts reflect broader governance and policy decisions that have shaped access and equity in hospital care.

CONCLUSIONS:
This research contributes to understanding the long-term effects of health system reforms on hospital service provision. It underscores the importance of historical data in evaluating policy outcomes and calls for sustained efforts to ensure equitable and sustainable public health governance.
