John Rex
Chief Financial Officer at UnitedHealth Group
Thank you, Dirk.
As Andrew noted, we entered the second half of this year with strong growth momentum. First half revenues of over $160 billion grew 13% compared to last year. Performance is well balanced, with double-digit growth at both Optum and UnitedHealthcare.
To begin, let me touch briefly on the care patterns we have observed so far this year. Principally, we have seen what had been a balanced relationship between COVID and non-COVID care activity over the past couple of years diverge modestly, with the latter not returning quite as rapidly with lower levels of COVID care. We also continue to see some variation in underlying care patterns, with certain areas remaining below historical levels; for example, pediatrics and emergency department, and others coming back more fully, such as the levels at which seniors are obtaining important preventative care. In recent weeks, we are seeing rising COVID-related hospital admissions, but with a lower average length of stay compared with earlier periods. As always, we watch closely for longer term health impacts on people due to care, which might have been deferred during earlier periods. Thus far, we are still not seeing patterns, which indicate shifting acuity.
There are of course many reasonable theories about what is driving the current environment, and they are all no doubt interesting, but here is what we are actually doing. Consistent with the long-standing practice at UnitedHealth Group, our primary intent is to ensure people are getting the care they need and to help them in that process as much as we can. We remain, as always, highly respectful of medical cost trends and how they can evolve rapidly, and we will continue to position our offerings accordingly.
Moving now to the businesses. Optum Health revenue grew by over $4 billion or 32% in the second quarter. Revenue per consumer increased 30%, led by growth in patients served under value-based arrangements. Earnings from operations rose 24% even as we accelerated investments in our care delivery practices to support value-based expansions. We also saw strong contributions from Optum's ambulatory surgery centers, which continue to advance the scope and complexity of procedures performed in these optimal settings, all while delivering a superior patient and surgeon experience and high-quality clinical outcomes.
Our centers have nearly tripled the number of high-acuity joint, spine and cardiovascular procedures performed compared to just two years ago. Care providers increasingly recognize the benefits these centers offer, and consumers place high value on the care quality and experience, with an NPS consistently in excess of 90.
Optum Insight revenue grew 11% year-over-year. The revenue backlog was $23.6 billion, growth of $2.3 billion compared to last year. We continue to drive technological advancements, applying artificial intelligence and machine learning more deeply in high-value knowledge-based services, including an expanding suite of information technology and data analytics offerings.
Optum Rx revenues grew 10% to nearly $25 billion, reflecting continued strong sales results and execution in the core PBM as well as our growth in our pharmacy care services. These vital and expanding care offerings serve and improve the health of people, including in such areas as our high-touch specialty services where we tightly monitor and track the effectiveness of complex treatments.
Turning to UnitedHealthcare. Revenue grew by a strong $6.6 billion or 12%, with contributions from all our businesses. In our offerings for seniors, we continue to expect to serve up to 800,000 additional people within Medicare Advantage this year. About three-quarters will be in individual and group Medicare Advantage and the remainder in Dual Special Needs Plans. This puts us on track for our seventh consecutive year of share gaining growth in Medicare Advantage.
People served by our Medicaid offerings grew by 180,000 in the second quarter. At this point, we anticipate the impact to Medicaid enrollment as a result of state redetermination activities will be experienced next year. We continue to prepare resources to help people find uninterrupted access to appropriate coverage as this transition occurs.
We added 80,000 new people in domestic commercial plans during the quarter. Within that, fully-insured commercial offerings grew by 60,000 from the first quarter of this year, with balanced growth across group and individual fully-insured offerings. Of note, some 90% of the growth within our individual and family plans was among people who chose a plan featuring convenient and cost-effective access to virtual visits.
Our capital capacities remain strong. Second quarter cash flows from operations were $6.9 billion or 1.3 times net income, and we continue to expect full year cash flows of about $24 billion. In the first half of this year, we returned nearly $8 billion to shareholders through dividends and share repurchase. In June, our Board increased the dividend by 14%, and we deployed more than $7 billion in capital to enhance our care delivery capacities and consumer strategies to improve outcomes and experiences for the people we serve and for the benefit of the broader health system.
As noted earlier, based on this growth outlook, today, we increased our adjusted earnings outlook to a range of $21.40 to $21.90 per share.
Now, I'll turn it back to Andrew.
