The interview data were checked against information obtained
from other sources (methodological triangulation), such as informal
conversations, observations and document reviews. The data were
also checked for consistency with insights from other respondents
(data triangulation). Results of the study were returned to key informants
in May 2013 for their additional reviews before completing
the final draft of the report to seek permission from the
informants for quotes. Two rounds of consultative meetings with
health system experts in March 2013 and June 2013 were convened
(10–12 participants/round) to report study progress and check the
accuracy of data interpretation.
