Information on the public’s health should be available to the public. I’m proud to announce @nycHealthy’s new Ensuring Transparency in Health Through Open Scholarship (ETHOS) policy, which ensures our published articles are available without a paywall.
Making research and data accessible is a top priority for @nycHealthy. We strive to make info about the public’s health – your health – available in many ways.
Our commitment to providing best-available COVID-19 data in useful ways throughout the pandemic is another example. #OpenDataWeek
Now, we’re expanding our commitment to ensure our scholarly articles, like this one, can be accessed for free online.
pubmed.ncbi.nlm.nih.gov/34961848/
We will make the default for agency scientists to publish in open-access peer-reviewed journals, or journals that offer an open-access option. 🔓 #OpenAccess
Authors will also submit complete manuscripts to #preprint servers so that findings are widely and promptly disseminated, and to invite feedback. Example: medrxiv.org/content/10.110…
This new policy is an important step in our commitment to transparency and being worthy of public trust.

For my final 🧵 as @NYCHealthCommr, I’d like to invoke a saying that I love: “It’s better to light a single candle than to curse the darkness.”
We have lived through a time filled with so many dark days, and so much suffering.
But public health, and the healing professions broadly, offered light during COVID. This wasn’t just about tests, medicines or vaccines, but speaking to New Yorkers’ fears, anxieties and uncertainties—and offering a roadmap for navigating them, even when solutions were imperfect.

New data from @nychealthy on racial inequities during the omicron wave in NYC explores why dramatic inequities experienced by Black New Yorkers throughout the pandemic became worse during the most recent surge: on.nyc.gov/3C7PUVu
Key analyses and ACTIONS🧵⬇️
Structural racism is a key driver of health inequity. We use the framework of a “COVID-19 prevention cascade” to map out factors rooted in anti-Black racism and provide a roadmap for achieving racial equity in #COVID19 outcomes, for NYC and beyond. @nychealthcmo
Since the start of the pandemic, Black & Latino New Yorkers and those in high-poverty neighborhoods have been less able to work from home. This led to increased COVID-19 exposure among these groups, though it does not fully explain the worsening inequities seen during omicron.

New: Preliminary findings related to the severity and impact of the surge of #COVID19 cases associated with the introduction of the #omicron variant to NYC: on.nyc.gov/3zTIDYk
Some key findings 🧵⬇
Omicron quickly became the most prevalent variant and led to a dramatic increase in reported cases. Whereas the delta variant became the dominant variant (from 0% prevalence to more than 90% prevalence) over a period of 20 weeks, omicron became the dominant variant in five weeks.
When the omicron variant emerged in NYC, it led to a steep rise in the number of people who visited emergency departments with COVID-like illness. Shortly afterward, the daily number of hospitalizations increased too.

Cardiac arrests are scary events that 350,000 Americans experience outside of hospitals each year, and only 10% survive. This story about my friend @kevin_volpp, a doctor & renowned researcher, highlights all the things that need to go right for survival.
heart.org/en/news/2021/1…
First, @kevin_volpp was with people who knew CPR and jumped into action right away. Then, first responders were called immediately and were able to use a defibrillator (AED) on him -- a critical device that can shock a heart back into rhythm if needed -- within a few minutes.
Once Kevin arrived at the hospital, he was treated immediately, with a “door-to-balloon” time of just 1 hour and 8 minutes, well below the @American_Heart target of 1 hour and 30 minutes.

.@nycHealthy's World Trade Center Health Registry recently investigated the association between 9/11-related post-traumatic stress disorder (PTSD), dust exposure and stroke among nearly 30,000 people in the Registry. 🧵

PTSD was significantly associated with increased risk of stroke. The likelihood of having recurrent strokes was also higher among those with PTSD versus those without PTSD.
Intense exposure to the dust cloud increased the odds of having a stroke significantly, but not for recurrent strokes.

In the winter of 1893-94, there was a smallpox outbreak in Brooklyn. While that was a long time ago — Brooklyn wouldn’t officially become part of NYC for another 4 years — many of the strategies used to fight the outbreak look familiar to us today. 🧵
Thanks to @NYCRecords’ efforts to digitize an enormous number of records from the municipalities that eventually became part of NYC as we know it, we can see how the Kings County Board of Health acted to stem the smallpox outbreak and keep residents safe.
Just like now, vaccinating workers was an important part of the effort — like at this bakery where a team of vaccinators took care of the whole workforce.
