Horizontal and vertical inequity of multi-modal healthcare accessibility in the aging Japan in the post-COVID era: a GIS-based approach
Evaluating the inequity of healthcare accessibility across demographic groups in the post-COVID era is of critical importance for an aging society like Japan – it helps to achieve better social equity via distributing healthcare resources in health planning and policy making. Our study contributes to the first post-covid evaluation of multi-modal healthcare accessibility in Tokyo, Japan, the most populated metropolis in the world. A further novelty goes to the multi-dimensional examination of the inequity of healthcare accessibility (i.e. hospitals) by public transit, driving and walking – the horizontal inequity across urban space and the vertical inequity across three demographic groups (the young, adult and elderly) through network analysis, spatial accessibility analysis and inequity indexing. We find that low healthcare access areas mainly appear in the peri-urban space as well as regions less covered by public transit. Compared to the adult group, the elderly group experiences significant inequity of healthcare access particularly in the peri-urban areas where driving is the dominant transport mode to access healthcare facilities. We provide timely evidence to the Japanese government and health authorities to have a holistic and latest understanding of multi-modal healthcare access across different demographic groups in the post-COVID era.</p

Relatedness between qLAMP and culture assays and cutoffs in different subgroups.
<p>Note: We only used the data from the three-time culture to test the consistency between qLAMP and culture assays. N and BX stand for not found and bronchiectasis, respectively.</p>*<p>In the piecewise linear regression of <i>S. pneumoniae</i> for child patients, all the detected titers were PCs (pathogen candidates), and no breakpoint was found. Therefore, the lowest titer detected in this subgroup is deemed as the upper cutoff.</p

qLAMP and culture result from LRTI patients.
<p>(A) The positive rates (the right vertical axis) of one-time culture (brown bar), three-time culture (blue bar), and quantitative LAMP (yellow bar) for the eight species in the panel (from the left: Ab, <i>A. baumannii</i>; <i>Ec, E. coli;</i> Hi, <i>H. influenzae;</i> Kp, <i>K. pneumoniae;</i> Pa, <i>P. aeruginosa;</i> Sa, <i>S. aureus</i>; Sm, <i>S. maltophilia;</i> and Sp, <i>S. pneumoniae</i>) detected from the number of patients (the left vertical axis). (B) The number of patients (the left vertical axis) who were tested positive for at least one bacterium in one-time culture, three-time culture, and qLAMP. Each bar is the sum of patient with single (blue bar) and multiple (yellow bar) species detected.</p
Examples of <i>S. pneumonia</i> showing the relationship between qLAMP and culture results (logistic regression) and cutoff determination based on competitive relationship (piece-wise linear regression).
<p>The horizontal axis displays the bacterial natural logarithmic titer in sputum sample. (A) Logistic regression curve (green line). Solid circles indicate patients; they are placed at the top of the chart when being test as positive and at the bottom of the chart when being tested as negative in the culture assays. The height and width of the bars display the frequency and the number of patients being tested positive in cultures, respectively. (B) Piecewise linear regression (black lines) of <i>S. pneumonia</i> in COPD patients. Open circles indicate patients; they are placed at the top of the chart when being PC (Pathogen Candidate) and at the bottom of the chart when NOT being PC.</p
