Yes. Lisa, and yes, thanks for the question. So on referral patterns, as you outlined, look, it still is very local as communities are dealing with the BA-5 strain, and that's kind of putting a little bit of disruption in patient visiting doctors or receiving elective surgeries or other aspects of that, so it truly is localized. We're not seeing kind of national patterns. And as we called out it was, although moving in a forward direction around hospital admissions and discharges, as you see in others as they report, it was modest growth. A lot of our focus is really on making certain that we are well prepared as an organization, as a partner of choice for those referral sources that we focus around reach and frequency of our teams, that we've got the right therapies on the shelf and staffing models in order to do that. And so we expect that it's going to remain a little bit choppy market by market as we continue to deal with different variants of the COVID strain, but feel like we're well positioned to be a partner of choice. And the investments that we've made into our core infrastructure and the 97 pharmacies that are operating effectively and efficiently, we feel well positioned from that side. On the second part of your question, on site of care, look, we continue to have really productive conversations with the payer community around their thoughts around -- not only think about site of care initiatives and making certain that they get that balance of cost quality aligned with member choice, and we're working closely to help support those efforts across the board. A lot of the investments that we're making not only into the nursing community, but also into the infusion centers across the country really dovetail and fit well within that overall strategy of moving more of the care closer to the home or into these dedicated site of care to align with the payers initiatives. And we feel as if the progress that we're making, opening over 25 this year and 6 in the quarter, just continues to position us well as the partner of choice as they're thinking about their network design and the partners that they want in network moving forward. Along that, with kind of the back part of that question, is we are seeing interest in narrowing of networks or the qualifications that the payers are looking for as that moves ahead. And we've done everything as part of our strategic moves to make certain that we are on the right side of any of those narrowing, given that fact that we can provide high-quality care consistently and effectively. And as I said in my prepared remarks, whether in New York City, Kansas City or Carson City, we've got a national network that really drives that consistent, high-quality care in a setting in which patients want to receive it.
