Scale-up of a novel vital signs alert device to improve maternity care in Sierra Leone: a mixed methods evaluation of adoption

Reprod Health. 2023 Jan 6;20(1):6. doi: 10.1186/s12978-022-01551-2.

Abstract

Background: The CRADLE (Community blood pressure monitoring in Rural Africa: Detection of underLying pre-Eclampsia) Vital Signs Alert device-designed specifically to improve maternity care in low resource settings-had varying impact when trialled in different countries. To better understand the contextual factors that may contribute to this variation, this study retrospectively evaluated the adoption of CRADLE, during scale-up in Sierra Leone.

Methods: This was a mixed methods study. A quantitative indicator of adoption (the proportion of facilities trained per district) was calculated from existing training records, then focus groups were held with 'CRADLE Champions' in each district (n = 32), to explore adoption qualitatively. Template Analysis was used to deductively interpret qualitative data, guided by the NASSS (non-adoption, abandonment, scale-up, spread, sustainability) Framework.

Findings: Substantial but non-significant variation was found in the proportion of facilities trained in each district (range 59-90%) [X2 (7, N = 8) = 10.419, p = 0.166]. Qualitative data identified complexity in two NASSS domains that may have contributed to this variation: 'the technology' (for example, charging issues, difficulty interpreting device output and concerns about ongoing procurement) and 'the organisation' (for example, logistical barriers to implementing training, infighting and high staff turnover). Key strategies mentioned to mitigate against these issues included: transparent communication at all levels; encouraging localised adaptations during implementation (including the involvement of community leaders); and selecting Champions with strong soft skills (particularly conflict resolution and problem solving).

Conclusions: Complexity related to the technology and the organisational context were found to influence the adoption of CRADLE in Sierra Leone, with substantial inter-district variation. These findings emphasise the importance of gaining an in-depth understanding of the specific system and context in which a new healthcare technology is being implemented. This study has implications for the ongoing scale-up of CRADLE, and for those implementing or evaluating other health technologies in similar contexts.

Plain language summary

Many women die during pregnancy and childbirth from causes that could be prevented, and the vast majority of these deaths occur in low-resource settings. The ‘CRADLE Vital Signs Alert’ is a medical device that helps identify problems during pregnancy—designed specifically for healthcare professionals in low-resource settings. However, for unknown reasons, the device appears to have varying impact according to the country or setting in which it is used. This study aimed to explore in depth whether, and why, healthcare professionals in Sierra Leone adopted the device and engaged in training (or not). Between March 2020 and January 2021, the CRADLE device and training package was disseminated across 8 districts in Sierra Leone. This relied on a few healthcare workers (nominated ‘CRADLE Champions’) to voluntarily distribute the devices and training in their local areas. Group discussions were held with CRADLE Champions in each district after the rollout to gather their feedback. In addition, the proportion of facilities trained in each district was recorded. The study found differences in how well the device and training was adopted in each district. Common challenges reported across districts related to technological difficulties (such as issues charging the devices) and organisational barriers (such as high levels of staff turnover at facilities). These findings will help to inform future rollout of the CRADLE device and training in Sierra Leone and highlight factors that may need to be considered by those implementing other health technologies in similar settings.
