[Editorial] COVID-19: learning as an interdependent world

The Lancet - Sab, 25/09/2021 - 00:00
There were some grounds for hope that the COVID-19 pandemic would be under control by now. Huge scientific advances have been made in our understanding of COVID-19, as well as its countermeasures. Countries have had 18 months to understand which policies work, and to develop strategies accordingly. Yet the pandemic is at a dangerous and shifting stage. Almost 10 000 deaths are reported globally every day. National responses to COVID-19 range from the complete lifting of restrictions in Denmark, to new state-wide lockdowns in Australia, and a growing political and public health crisis in the USA.

[Perspectives] An inclusive worldview: Amartya Sen's memoir

The Lancet - Sab, 25/09/2021 - 00:00
Amartya Sen's contributions to economics, social science more generally, and philosophy are so profound and wide-ranging that they defy easy categorisation. In addition to his technical work on the appropriate choice of technology in low-income and middle-income countries and on the axiomatic underpinnings of social choice theory, he has broadened the scope of enquiry to bring in more complex approaches to the idea of development, the explicit analysis of deprivation, how to capture and measure wellbeing and inequality, the nature of human freedom, our understanding of democracy, and much else.

[Perspectives] Waheed Arian: supporting health care in conflict zones

The Lancet - Sab, 25/09/2021 - 00:00
Waheed Arian is an accident and emergency doctor at Shrewsbury and Telford Hospital NHS Trust in the UK and an NHS Innovation Clinical Entrepreneur Fellow and Mentor. But his journey to becoming a doctor was challenging. Born in Kabul in 1983, the first 5 years of his life were spent in hiding from rockets, bombs, and shelling, until his family migrated to Pakistan for their safety. For the next 3 months their home would be the Babu refugee camp near the city of Peshawar. At the camp, Arian became malnourished and contracted malaria and tuberculosis.

[Correspondence] From nurse-to-patient ratio to optimal team composition

The Lancet - Sab, 25/09/2021 - 00:00
We congratulate Matthew D McHugh and colleagues1 for showing the higher value of care delivered to the population after improved hospital staffing levels. This quasi-experimental evaluation surpasses previous observations showing a statistical relationship between the nurse-to-patient ratio and care safety.2

The Lancet - Sab, 25/09/2021 - 00:00
In 2016, the state of Queensland, Australia, established a policy limiting the average number of patients per nurse for adult medical surgical wards in 27 public hospitals that treated more than half of the state's adult acute care admissions. Queensland was motivated by research showing that better hospital nurse staffing is associated with better patient outcomes, as well as growing international efforts to translate this research into effective policy.1

[Correspondence] The evidence gap in low back pain management strategies

The Lancet - Sab, 25/09/2021 - 00:00
In their Seminar1 on low back pain, Nebojsa Nick Knezevic and colleagues state that “MRI…can contribute to higher rates of spine surgery and result in higher satisfaction rates”.

[Correspondence] The evidence gap in low back pain management strategies

The Lancet - Sab, 25/09/2021 - 00:00
In their Seminar,1 Nebojsa Nick Knezevic and colleagues concluded that surgery is more effective than conservative management in the treatment of lumbar spinal stenosis, and that decompression combined with fusion had no substantial benefit compared with decompression alone. We believe that this conclusion was not evidence-based, and could have the potential to prejudice the spine surgeon against the choice of treatment for lumbar spinal stenosis.

The Lancet - Sab, 25/09/2021 - 00:00
We thank Xing Du and Yunsheng Ou for bringing up the contentious issue of spine surgery for further discussion. However, we do not agree that the conclusions in our Seminar1 oppose evidence-based medicine; rather, we believe that they bolster the argument that there is insufficient evidence to draw firm conclusions.
