Exploring barriers and enabling factors for surgical task sharing with physician assistants in Liberia: a qualitative pre-implementation study.

OBJECTIVES: This study explores potential barriers and enabling factors that may influence the acceptance of implementation of a surgical task-sharing initiative targeting physician assistants (PAs) in Liberia. DESIGN: A qualitative, pre-implementation study using semistructured interviews. Data was analysed in NVivo V.12 using deductive coding and the consolidated framework for implementation research as a guide. SETTING: Liberia has few surgical providers and a poor surgical infrastructure resulting in a very low surgical volume. The research was conducted in the context of an already running surgical task-sharing programme for midwives. PARTICIPANTS: In 2019, a total of 30 key stakeholders in the field of surgery and the PAs training programme were interviewed. RESULTS: The majority of the stakeholders supported the idea of training PAs in surgery. The high unemployment rate among PAs and the need for career advancement of this cadre were important enabling factors. Resistance against surgical task sharing for mid-level clinicians is multifaceted. The Ministry of Health (MOH) did not share a common vision. Opponents within the MOH believed budgetary constraints within the MOH and the lack of surgical infrastructure is a more pressing problem compared with the surgically trained human resources. Another important group of opponents are medical officers (MOs) and their professional bodies. Many of their negative beliefs around surgical task sharing reflect lessons to be drawn from the current surgical training programme for midwives. CONCLUSION: Prior to deciding on implementation of a surgical training programme for PAs, wider support is needed. If surgical task sharing with PAs is to be considered, the intervention should focus on adapting the 'adaptable' periphery of the intervention to broaden the support of the MOH, MOs and their professional bodies. Failing to obtain such support should make the implementors consider alternative strategies to strengthen surgical human resources in rural Liberia.

The economic burden associated with unmet surgical needs in Liberia: a retrospective macroeconomic analysis based on a nationwide enumeration of surgical procedures.

OBJECTIVES: The economic consequences of untreated surgical disease are potentially large. The aim of this study was to estimate the economic burden associated with unmet surgical needs in Liberia. DESIGN: A nationwide enumeration of surgical procedures and providers was conducted in Liberia in 2018. We estimated the number of disability-adjusted life years (DALYs) saved by operative activities and converted these into economic losses averted using gross national income per capita and value of a statistical life (VSL) approaches. The total, the met and the unmet needs for surgery were determined, and economic losses caused by unmet surgical needs were estimated. Finally, we valued the economic losses avoided by various surgical provider groups. RESULTS: A total of 55 890 DALYs were averted by surgical activities in 2018; these activities prevented an economic loss of between US$35 and US$141 million. About half of these values were generated by the non-specialist physician workforce. Furthermore, a non-specialist physician working a full-time position for 1 year prevented an economic loss of US$717 069 using the VSL approach, while a specialist resident and a certified specialist saved US$726 606 and US$698 877, respectively. The burden of unmet surgical need was associated with productivity losses of between US$388 million and US$1.6 billion; these losses equate to 11% and 46% of the annual gross domestic product for Liberia. CONCLUSION: The economic burden of untreated surgical disease is large in Liberia. There is a need to strengthen the surgical system to reduce ongoing economic losses; a framework where specialist and non-specialist physicians collaborate may result in better economic return than a narrower focus on training specialists alone.
