Thanks, Scott, and good morning. Today, I'll discuss our 2018 results as well as our outlook for 2019. For the full year 2018, we achieved ongoing earnings per share of $2.88, representing 15% growth versus the prior year. Strong performance across our businesses, along with underlying margin expansion and our synergy capture from recent acquisitions, enabled us to achieve EPS at the upper end of the initial guidance range we issued at the beginning of last year despite unfavorable currency shifts as we progressed through the year.
With our recent strategic shaping completed, our focus in 2018 was on running the company we've built, and the result was an excellent year by every measure. All 4 of our major businesses performed well, contributing to overall organic sales growth of more than 7%, which is above the initial guidance range we set at the beginning of last year. At the same time, we generated operating cash flow of more than $6 billion, returning $2 billion to shareholders in the form of dividends, and announced a 14% increase in our dividend beginning this year.
We also increased our investments in capabilities for the future, including expanding manufacturing capacity in 2 important areas that will drive significant long-term growth: FreeStyle Libre, our revolutionary continuous glucose monitoring system; and Alinity, our family of highly differentiated diagnostic systems.
And lastly, following 2 major acquisitions in 2017, we repaid more than $8 billion of debt, which significantly enhances our strategic flexibility going forward.
Our performance this past year demonstrates the strength of our strategy and execution. And for 2019, we're forecasting another year of strong financial performance. As we announced this morning, we forecast organic sales growth of 6.5% to 7.5% and adjusted earnings per share of $3.15 to $3.25, reflecting double-digit growth.
I'll now provide a brief overview of our 2018 results and 2019 outlook for each business. I'll start with Nutrition, where sales increased mid-single digits in 2018, reflecting a notable improvement in our growth rate versus the prior year. Sales growth this past year was well balanced across our Pediatric and Adult Nutrition businesses.
Internationally, our focus on enhancing competitiveness with our well-known and trusted brands led to strong growth in both Asia and Latin America. In China, we saw improvement in both the market and our performance after the government transitioned to new food safety regulations in that country at the beginning of last year.
And in the U.S., growth was driven by our Pediatric Nutrition business, led by above-market growth of Similac, our market-leading infant formula brand; and Pedialyte, our market-leading rehydration brand. Overall, the fundamental demographic and socioeconomic trends in the global nutrition market remain favorable, and our position in the market remains very competitive.
In Established Pharmaceuticals, or EPD, sales grew 7% in 2018, led by double-digit growth in both India and China. Our strategy in EPD is unique and quite simple: to build significant presence, scale and leadership positions in the most attractive emerging markets where long-term growth in medicines will be driven by aging populations and the related rise in chronic diseases, increasing incomes and expanding access to care.
We've built our business over time through a series of strategic steps to be powered globally but driven locally. Our global scale sets us apart and provides a unique competitive advantage versus local players, particularly when it comes to manufacturing and innovation. And our local decision-making allows us to be nimble and navigate the complexities of each country. Health care spending in most emerging markets is less than half that of developed markets, which means there's lots of room for future growth. And our focus continues to be on strong execution across all elements of our business model to capitalize on the growth opportunities ahead.
Moving to Diagnostics, where we've consistently achieved above-market growth with our leading platforms. 2018 was no different with global organic sales growth of 7%. This past year was particularly important as we accelerated the launch of Alinity, our family of highly differentiated instruments in Europe and other international markets. Customer feedback has been outstanding, which, quite frankly, isn't a surprise to us given that Alinity was designed based on countless hours of listening to and observing the needs of our customers. These systems are designed to be more efficient, running more tests in less space, generating results faster, minimizing human errors while continuing to provide quality results. In 2019, while the international launch continues to gain momentum, we anticipate obtaining U.S. regulatory approvals for a critical mass of our test menu over the coming months, which will allow us to accelerate the launch of Alinity in the U.S. later this year.
2018 was also an important year for our newly formed Rapid Diagnostics business. We achieved our sales and synergy targets for the year and are very pleased with the pace and progress of the integration of this business. We also made important advancements in our pipeline with new product launches in the areas of diabetes and cardiac care as well as molecular rapid tests for infectious diseases. These new products, along with continued focus on strong execution across our portfolio, will drive accelerated growth for this business going forward.
And lastly, I'll cover Medical Devices, where sales grew 9% in 2018, exceeding the initial guidance range we set at the beginning of the year. Strong growth this past year was led by several areas, including Electrophysiology, Structural Heart and Diabetes Care, as well as stabilization in our Rhythm Management and Vascular businesses.
In Electrophysiology, growth of 20% was led by our heart mapping and ablation portfolio. During the year, we advanced our product portfolio in this area with the launch of our Advisor HD Catheter, which creates highly detailed maps of the heart. And earlier this week, we announced U.S. FDA approval of our innovative TactiCath Sensor Enabled Catheter, which will further strengthen our competitiveness in this highly underpenetrated market.
In Structural Heart, 2018 was a landmark year for our business. We achieved double-digit growth and, perhaps more importantly, announced clinical trial results for MitraClip, our market-leading device for the minimally invasive repair of the mitral valve, which demonstrated improved survival and clinical outcomes in patients with the most prevalent form of this heart disease. We submitted this study data to the U.S. FDA during the fourth quarter to support consideration of an expanded indication for MitraClip. If approved, this advancement would further enhance our leadership position in this large and highly underpenetrated disease area and offer the potential to create a new multibillion-dollar cardiac device market over time.
And lastly, in Diabetes Care, we achieved growth of 35% in 2018. Growth was led by FreeStyle Libre, which achieved global sales of more than $1 billion, an increase of 100% versus the prior year. During the fourth quarter, we added 300,000 new users. As of the end of 2018, there are now approximately 1.3 million active users worldwide, of which approximately 2/3 are type 1 diabetics and 1/3 are type 2.
In the U.S., we saw an accelerating trend of new users as we ramped up our awareness efforts during the second half of the year, and pharmacy insurance coverage continued to increase, including an emerging trend of seeing Libre granted preferred copay status versus competitive systems due to its compelling overall value proposition.
In Europe, during the fourth quarter, we initiated the launch of Libre 2.0, which includes optional alarms that warn patients if glucose levels fallout range. Due to our unique product design and a highly automated manufacturing process, we're able to offer this feature to Libre users without increasing the cash pay price. This affordable and simple-to-use device is fundamentally changing the way people with diabetes manage their disease. And given the fact that more than 400 million people are living with diabetes around the world, Libre promises to be a significant growth driver for years to come.
So in summary, 2018 was another outstanding year for us. We achieved our strategic and financial objectives despite challenging currency shifts during the year. Our top-tier performance demonstrates the strength of our strategy, our portfolio and our execution. And for 2019, we're forecasting continued strong organic sales growth and double-digit EPS growth.
I'll now turn the call over to Brian to discuss our 2018 results and our 2019 outlook in a bit more detail. Brian?
