The wider societal benefits of surgical interventions for lymphatic filariasis morbidity management and disability prevention

Lymphatic filariasis (LF) is targeted for global elimination as a public health problem by interrupting transmission with mass drug administration and providing an essential package of care to people affected by the debilitating lymphedema and hydrocoele conditions [1]. In recent years, many LF endemic countries have scaled up their morbidity management and disability prevention (MMDP) programmes with a new focus on universal health coverage, primary healthcare strengthening, and integrated management of skin neglected tropical diseases (NTDs), with the aim of fully integrating quality services for LF MMDP into national health systems to ensure sustainability [2].

The positive impact of MMDP interventions for patients has been documented [3–6]; however, no research has been conducted on the wider societal benefits, including the impact on the people who care for patients, i.e., caregivers. Ton and colleagues [7] calculated that the burden of depressive illness in LF patient caregivers was 229,537 disability-adjusted life years (DALYs). Other studies have documented a negative socioeconomic impact on the caregivers of people affected by filarial and nonfilarial leg lymphedema and those who experience painful secondary bacterial infections, acute adenolymphangitis [8–10].

Hydrocoele is the most common LF clinical manifestation, which affects approximately 19 million men worldwide and can be cured by surgery [11]. In Malawi, recent large-scale patient mapping and modelling estimate that at least 14,000 men have hydrocoele across the country. In 2015, surgical campaigns were initiated to address the burden, together with a study to highlight the significant positive impact of surgery on men in highly endemic areas [4].

We advocate that the positive impact of this surgical intervention can extend beyond the patient to include their caregivers, who are likely to be family members (predominately female) and have their own time, work, and quality of life affected.
