Universal masking at Mass General Hospital was associated with a significantly lower rate of SARS-CoV-2 positivity among health care workers. This association may be related to a decrease in transmission.
However, randomized trials of universal masking during a pandemic are likely not feasible.
Nonetheless, these results support universal masking as part of a multipronged infection reduction strategy in health care settings.
Opioid epidemic in one chart – correlation conflated with causation
There is no cause-and-effect relationship between prescribing and overdose mortality. But millions of patients are being denied safe and effective pain care.
Seniors over age 62 are prescribed opioids for pain three times more often than youth under age 19. But youth have overdose rates three times higher than seniors. No medical model can explain these demographics.
