Evaluating the impact of health resource reconstruction on improving spatial accessibility of tuberculosis care
Setting:
In Japan, a decline in tuberculosis (TB) notification rates and shortening of duration of hospitalisation have led to a drastic decrease in the number of hospital beds for TB patients (TB beds), causing severe undersupply in certain regions.
Objective:
To assess the current status of spatial access to TB beds in Japan and evaluate the potential impact of health resource reconstruction in mitigating undersupply of TB beds.
Design:
A cross-sectional study was conducted whereby a two-step floating catchment area (2SFCA) method was used to calculate an 'accessibility score' to evaluate spatial accessibility of TB beds in the regions classified by four levels of urbanisation. The impact of introducing 'potential TB beds' was assessed via the changes in the proportion of undersupplied regions and TB patients notified from undersupplied regions.
Results:
Undersupplied regions were characterised by 'very low', 'low' and 'moderate' level of urbanisation. By introducing 'potential TB beds', the proportion of both undersupplied regions and TB patients could be significantly reduced, especially in less urbanised regions.
Conclusion:
Our results may be used to guide future decision-making over resource allocation of TB care in Japan. The 2SFCA method may be applied to other countries using appropriate demand and supply variables.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
