Frequently Asked Questions


Why is the conference offered in a hybrid format rather than fully virtual or fully in person?
We realize that many people will be unable to travel to The Woodlands, TX, due to travel restrictions, financial considerations, or safety concerns. We also recognize that the social and professional interactions at an in-person conference cannot be replicated in a virtual format. Therefore, the 54th LPSC will be delivered in a hybrid format, which will allow the widest possible participation.

What does it mean that the 54th LPSC is a hybrid conference?
The 54th LPSC is being planned as a hybrid conference, with attendees having the option of registering to attend in person in The Woodlands, Texas or virtually. All registered attendees (in-person and virtual) will have access to streamed in-person content and on-demand oral sessions, iPosters, press conferences, and plenary sessions.

Both in-person and virtual registration include access to on-demand content on the virtual platform for 30 days after the conference.

Do virtual attendees need to download or install any software to participate in the conference?
No, attendees just need a standard web browser and a stable internet connection to access the virtual conference website.

COVID-19 Protocols

What COVID-19 protocols will be in place for in-person attendees at the 54th LPSC?
Our highest priority remains the health and safety of everyone attending the conference. We are closely monitoring news and guidance from the Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and local health agencies regarding travel and large events. Please visit LPSC COVID-19 Protocols to learn more.

Will in-person attendees be required to wear masks?
Yes, regardless of your vaccination or natural immunity status, all conference attendees and volunteers will be required to wear a face mask while in the convention center and riding on the shuttle buses. Masks can be removed temporarily when actively eating or drinking. In-person speakers in oral sessions can choose to remove their masks while presenting. In-person poster presenters must remain masked due to the close proximity to fellow attendees.

Will proof of full vaccination be required to register and attend the conference?
At this time, we will not require in-person attendees and volunteers to demonstrate proof of full vaccination. However, we will closely monitor local area case rates and guidance from health agencies. If warranted, changes to this policy may be made. Please check LPSC COVID-19 Protocols regularly for updates.

Will physical distancing be implemented at the conference venue?
Yes, LPSC organizers will modify floor plans and seating so that attendees can maintain appropriate physical distancing. Signs will be posted to remind attendees about physical distancing. Attendees will have the option to display color-coded labels to indicate their comfort level with physical proximity and contact.

If I test positive for COVID-19 during LPSC, how do I report my test result?
Attendees who receive a positive test result during LPSC are not allowed to enter the conference venue and must immediately quarantine. These attendees are encouraged to share positive test results with a USRA/LPI HR representative: [email protected]. For contact tracing purposes, a list of close contacts without masking will be requested. All information will be considered as HR confidential.


Do I need to register to attend the 54th LPSC?

All attendees logged into the virtual platform should use the Zoom Webinar Q&A feature to ask questions during the oral sessions. Attendees can upvote a question by clicking the thumbs-up icon. Each live oral session will have session chairs and a moderator to monitor the Q&A and convey questions submitted by virtual attendees. The speakers will do their best to answer as many questions as possible during the allotted time.

How do I distinguish between virtual and in-person speakers in the conference program?
There is no distinction in the conference program for virtual or in-person oral presentations to ensure equal stature among all speakers. Oral sessions will include a mixture of in-person and remote presentations, all of which will be streamed live.

Poster Sessions
