Investing in public health is our best route to sustainable healthcare

Has it all been worth it: the handwashing, the mask wearing, the standing 2 m apart? 

The available evidence suggests it has. 

A systematic review published this week finds that these measures have reduced transmission of SARS-CoV-2 and deaths from covid-19 . 1


The conclusions are encouraging, but the paucity of good evidence for public health interventions during the pandemic is not. 

Among 35 studies good enough to evaluate, only one was a randomised trial, and it was too small . 2 

The others were all observational studies, including natural experiments, and the effects are likely to result from “bundles” of protective behaviours rather than single interventions.


We lack even this level of evidence to weigh up the benefits and harms of lockdowns, quarantine, isolation, closures of borders, schools, and workplaces, or increased indoor ventilation and outdoor socialising. 

This evidence deficit is one of the research tragedies of the pandemic, say Paul Glasziou and colleagues . 2 

Only 4% of the world’s funding for covid-19 research has gone into public health measures. 

Better studies are on the horizon, in particular two large cluster randomised trials of mask wearing in Bangladesh and Guinea-Bissau. 

Better evidence should encourage more informed decision making.

Might it also improve the quality and civility of scientific debate, giving us something to get our teeth into rather than each other? 

  • The pandemic’s evidence vacuum has certainly contributed to the bitterness of the pandemic debate (3).
  • But doctors have always been rude to each other, says Agnes Arnold-Forster , 4 and the tenor of the current debate is not a product of the pandemic. 

We shouldn’t deny the emotional, cultural, and political nature of medicine and science, she says. Indeed we should lean towards politics rather than turning away.


So, let’s lean into the politics of healthcare funding. 

  • The UK spends less of its GDP on health than European comparators, with fewer doctors, nurses, and hospital beds per head than Germany and France. 
  • We are in the midst of an escalating staffing crisis , 5 6 for which the government’s spending plans are wholly inadequate . 7 8 
  • Those currently working in the service are stretched far beyond what is reasonable or safe, for them or their patients. 
  • Poor quality of care quickly becomes normalised, says Mary Dixon-Woods in the first episode of our new Doctor Informed podcast . 9 We must fight against this. 10

How can we make healthcare more sustainable, for those working in it, for national economies, and for the planet ? 11 

Here are two things we must do. 

  • First, we must stop providing low value interventions, where the harms or costs outweigh the benefits 12 13 

Tight control of type 2 diabetes in elderly people is one example , 14 and you’ll find more ideas and inspiration in another podcast launched this week, the Recovery . 15 16 

  • Second, because any healthcare system will fall over unless we improve the health of populations, we must press our political leaders to invest in public health.

Conclusions

This systematic review and meta-analysis suggests that several personal protective and social measures, including 

  • handwashing, 
  • mask wearing, and 
  • physical distancing 

are associated with reductions in the incidence covid-19. 


Public health efforts to implement public health measures should consider community health and sociocultural needs

and future research is needed to better understand the effectiveness of public health measures in the context of covid-19 vaccination.
