Table 4 HCW time required for each encounter/activity in the LTBI Cascade of Care, by country income level and cadre of workers (from linear mixed model)

From: Resource implications of the latent tuberculosis cascade of care: a time and motion study in five countries

  1. aCanada is the one high-income country
  2. bLMICs include: Benin, Ghana, Indonesia, and Vietnam
  3. cIn the LMM for Step #5, there was not a statistically significant interaction between type of HCW and setting, so the expected difference between doctors and nurses is the same whether in HIC or LMIC settings
  4. *Note: Where the CI lower limit is below zero, values were cut-off at 0 minutes
