The remaining 7 transcripts were used to confirm the themes and dimensions.
Codes were discussed with other members of the research team who reviewed up to five transcripts each to confirm the themes arising from the primary researcher's analysis.
Two authors then read the transcripts to confirm the themes, and key findings were reviewed in feedback sessions with each team.
Each interview and focus group transcript was then reviewed independently by a second researcher (INA) to confirm the themes identified and identify any important omissions.
Table 2 indicates that the study reached data saturation at interview 3; every interview beyond that served to confirm the themes that emerged in the first three interviews, rather than introduce new themes.
Codes identified in these meetings were entered into N-Vivo (version 9.0), a qualitative data analysis and organization software program, to confirm the themes that the research team had manually identified.
A separate respondent group of 19 patients and spouses who met the inclusion criteria reviewed and confirmed the themes developed from the initial couples.
Following the two phases of data collection, tapes were transcribed verbatim and a random sample translated from Swahili into English for the non-Swahili speaking senior co-investigator to confirm the emerging themes and provide feedback.
43 The analyses were led by CH, ASD, RF and MP analysed a subset of transcripts to confirm the main themes (ASD and MP reviewed five and RF reviewed six transcripts).
The final template, consisting of the superordinate and subordinate themes, was reviewed by PRN and DP to confirm the relevance of the themes to medication safety.
