At Ridge hospital, cryo guns were replaced every year. At Kumasi South hospital: every other year.
Ridge hospital performed 45 procedures in 2008. Based on an observed VIA positivity rate of 2.53%, assuming 200 screens at low case load facilities would yield about 5.1 positive screens per year.
At Kumasi South hospital: 17 min. At Sepe Dote: 45 min. In Goldie et al. (2001): 15 min.
At Kumasi South hospital: 45 min. At Ridge hospital: 60 min.
Estimated effective working time at Kumasi South and Komfo Anokye hospital: 60%.
Same as in Legood et al. (2005) and supported by Ghana findings.
