Table 2 Household indirect costs of treating BU, Ghana, 2012

From: Household cost of out-patient treatment of Buruli ulcer in Ghana: a case study of Obom in Ga South Municipality

Indirect costs Time Estimation approach
Travel time Patient Summation of the product of the number of visits by BU patients to OHC per week by doubled travel time (i.e., to and fro OHC) and normalized by sample size.
  Caregiver Summation of the product of the number of visits by caregivers to OHC per week by doubled travel time (i.e., to and fro OHC) and normalized by sample size.
  Total travel time Summation of patient and caregiver travel times.
Wound dressing time Patient Summation of the product of time spent on wound dressing (i.e., waiting and dressing) by the number of wound dressing times per week by the number of weeks of wound dressing and normalized by sample size.
  Caregiver Summation of the product of the caregiver’s waiting time spent on wound dressing by the number of wound dressing times accompanied by caregiver per week by the number of weeks of wound dressing accompanied by caregiver and normalized by sample size.
  Total wound dressing time Summation of patient and caregiver travel times.
Valuation Type of cost Cost (US$ per year)
  Productivity lost by patient Summation of the product of the total number of workdays lost by adult BU patients in seeking health care (i.e., travel and wound dressing times) by the average local daily wage rated.
  Productivity lost by caregiver Summation of the product of the total number of workdays lost by caregivers in seeking health care (i.e., travel and wound dressing times) by the average local daily wage rated.
  Total indirect cost (i.e., productivity lost) This is the summation of valued productive days lost by patient and caregiver.
