[Perspectives] How imperialism, slavery, and war shaped epidemiology

The Lancet - Sab, 16/10/2021 - 00:00
In recent decades, historians have become increasingly attuned to the ways in which empire and imperialism transformed modern conceptions of disease, medicine, and the body. Such scholarship argues that European medical theories were not simply disseminated in imperial territories and that science and medicine should not only be seen as scientific and cultural projects that consolidated imperialism. Instead, the thrust has been to understand how the development of modern ideas of hygiene, sanitation, public health, and disease were themselves produced out of an encounter with empire and subjugated populations.

[Perspectives] Superhuman, but never enough: Black women in medicine

The Lancet - Sab, 16/10/2021 - 00:00
Historically, Black women have long been disregarded in the USA. The Three-Fifths Compromise of the US Constitution discounted Black women as only “part” of a human being, to be counted for congressional representation and direct taxation but nothing more. Even in prominent social justice movements, Black women have been excluded. Racism and elitism were embedded within the 19th-century and early 20th-century US women's suffrage movement, which prioritised white women over voting rights for all women.

[Correspondence] Telehealth use in antenatal care? Not without women's voices

The Lancet - Sab, 16/10/2021 - 00:00
Kirsten R Palmer and colleagues1 assessed integrated telehealth for antenatal care in Australia during the early COVID-19 pandemic. However, the estimated 50% reduction of in-person consultations does not represent the proportion of telehealth consultations received by women. Women included in the intervention gave birth between March 23 and July 26, 2020, which is equivalent to, at most, 4 months of a telehealth-integrated antenatal care schedule. Although not presented, the average duration of antenatal follow-up was probably 2 weeks (implementation period) and 6 weeks (integrated care period), allowing for a maximum of two telehealth visits with three face-to-face consultations.

The Lancet - Sab, 16/10/2021 - 00:00
We thank Anna Galle and colleagues for progressing the conversation about quality and equity in antenatal care. Although our analysis of telehealth integrated care addressed the initial 4 months following widespread telehealth integration and analysed data following birth only,1 this means that women included in the analysis were predominately in the third trimester of pregnancy, a time when most pregnancy complications arise. The fact that women in their final stages of pregnancy received, on average, 40% of consultations via telehealth without an impact on the quality of their pregnancy outcomes remains heartening.

Evaluation of progress toward universal health coverage in Myanmar: A national and subnational analysis

Background

Universal health coverage (UHC) encompasses 2 main components: access to essential healthcare services and protection from financial hardship when using healthcare. This study examines Myanmar’s efforts to achieve UHC on a national and subnational level. It is a primer of studying the concept of UHC on a subnational level, and it also establishes a baseline for assessing future progress toward reaching UHC in Myanmar.

Methods and findings

The study uses the Demographic and Health Survey (2015) and the Myanmar Living Conditions Survey (MLCS; 2017) and adapts a previously developed UHC index to provide insights into the main barriers preventing the country’s progress toward UHC. We find a negative correlation between the UHC index and the state/region poverty levels. The equity of access analysis reveals significant pro-rich inequity in access to all essential healthcare services. Socioeconomic status and limited availability of healthcare infrastructure are the main driving forces behind the unequal access to interventions that are crucial to achieving UHC by 2030. Finally, financial risk protection analysis shows that the poor are less likely to use healthcare services, and, once they do, they are at a greater risk of suffering financial catastrophe. Limitations of this study revolve around its correlational, rather than causal, nature.

Conclusions

We suggest a 2-pronged approach to help Myanmar achieve UHC: Government and state authorities should reduce the financial burden of seeking healthcare, and, coupled with this, significant investment in and expansion of health infrastructure and the health workforce should be made, particularly in the poorer and more remote states.
