Reducing healthcare access inequities in West Java through forecasting and location-allocation models.
Article in BMC health services research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEnsuring equitable access to healthcare services is paramount for the enhancement of societal welfare and the optimisation of public health outcomes. Within the context of West Java Indonesia, accelerated population growth coupled with geographic disparities has resulted in heightened pressure on the existing healthcare infrastructure, thereby rendering numerous communities inadequately served. Although CHCs are already widespread in Indonesia, their distribution remains uneven, especially in growing urban areas. Consequently, there is growing recognition of the need to strategically expand community healthcare centres (CHCs) to improve access across underserved areas. These CHCs are instrumental in providing vital services, encompassing preventive care, maternal and child health, immunisation, dental services, and outpatient care.
methodsThis study presents an integrated approach combining population forecasting, spatial demand estimation, and optimisation modelling to support long-term planning of CHCs in Kota Bandung. Kota Bandung was selected as the study area due to its high population density, significant spatial disparities in healthcare access, and strategic importance in regional health planning. Using an ARIMA model, the researchers forecasted population growth through 2045. The year aligns with Indonesia's national long-term vision, Visi Indonesia 2045. They then estimated daily CHC demand using spatial grid and population density data, applying a standard utilisation rate. Three mixed-integer linear programming (MILP) models were developed to optimize facility locations by maximizing coverage, minimizing travel time, or balancing both. This method allows planners to explore various scenarios based on local needs and constraints.
resultsThe forecasting model reveals a consistent escalation in the demand for primary healthcare services within the Bandung region, with distinct growth hotspots identified in presently underserved locales. Optimisation scenarios produced by the MILP models indicate that the strategic positioning of new CHCs can substantially augment service coverage while simultaneously mitigating disparities in healthcare access. Scenario-based simulations were conducted to explore how different planning objectives-such as maximizing coverage or minimizing travel time-impact CHC placement outcomes. The results suggest that the most equitable arrangement of CHCs would enhance accessibility for marginalized populations by more closely aligning resources with geospatial demand.
conclusionThis integrated modelling framework presents a pragmatic paradigm for long-term health infrastructure planning in contexts characterized by resource limitations. By synthesizing demand forecasting with location-optimisation methodologies, regional health authorities are empowered to make data-informed decisions to enhance access and equity in primary healthcare services. These findings bolster broader initiatives aimed at achieving Universal Health Coverage in Indonesia.
