Thanks, Steve. Before discussing the financial results, I'd like to highlight that we will be retroactively reporting the Financial Services segment as a discontinued operation, starting with the second quarter of fiscal 2022. Therefore, our updated reporting segments are comprised of continuing operations from Chamberlain, Walden and Medical and Vet as presented in the 8-K filed today.
Beginning with the third quarter of fiscal 2022, we'll be making the following two changes to our disclosures. First, in addition to operating income, we will also disclose total and segment level EBITDA which we believe will provide additional insights into the performance of our businesses. Second, we will transition enrollment data to focus exclusively on total enrollment which we believe is the metric that most closely correlates with future revenue given that it contemplates both new enrollment and student persistence.
Let me now provide a summary of our financial performance for the continuing operations during the quarter. Revenue in the second quarter increased 58.4% to $371.2 million compared with the prior year, driven by the acquisition of Walden. Consolidated operating income, excluding special items in the second quarter, was $70.2 million, a 70% increase compared with the prior year due to the addition of Walden. Net income from continuing operations, excluding special items, was $37.8 million, a 17.3% increase compared with the prior year, driven by higher operating income from Walden, which was partially offset by additional interest expense. Diluted earnings per share, excluding special items, for the quarter was $0.75, an increase of 23% compared with the same period in the prior year.
Next, I'll discuss the highlights of the second quarter by segment. The Chamberlain segment reported second quarter revenue of $139.1 million, a decrease of 2% when compared with the prior year and operating income of $25.5 million versus $32.5 million in the prior year. The decrease in operating income was primarily the result of the decline in revenue, higher costs associated with return to in-person campus instruction and higher cost of marketing.
New and total student enrollment in the November session decreased 0.5% and 2.1%, respectively, compared with the prior year. We believe the decrease in new student enrollment was primarily attributable to COVID-related headwinds in our post-licensure programs as the recent surge further burdened nurses, leading to fewer new starts.
However, our pre-licensure programs performed relatively well due to improved persistence. We expect the COVID headwinds to subside over time and believe that demand for nurses will continue to outpace supply over the long term, representing strong growth opportunities for us in the future.
Turning to Walden. Revenue in the second quarter was $140.6 million. The segment operating loss was $2.4 million, driven primarily by intangible amortization expense. Segment operating income, excluding special items, was $32.4 million. New and total student enrollment during the quarter decreased 18.3% and 9.1%, respectively, compared with the prior year. Walden enrollment was disproportionately impacted by COVID-related headwinds in post-licensure programs, which dominate the student mix within the segment.
In contrast, Chamberlain has a significant percentage of pre-licensure programs, which have not been as negatively impacted by COVID headwinds and their November enrollment session occurred prior to the Omicron surge. As a result, post-licensure nursing and nonhealth care focused programs experienced the most significant headwinds while social and behavioral science programs continued to perform relatively well. Our integration efforts are progressing well, and we remain on track to realize the $60 million of annual run rate cost synergies within the first 2 years of Walden ownership.
In our Medical and Vet segment, revenue of $91.5 million declined 1% compared with the prior year. Segment operating income increased from $18.8 million to $19.5 million, driven primarily by lower expenses. While performance of this segment has been relatively stable, we remain optimistic that recent leadership changes in our new operating model will accelerate revenue growth and margin expansion.
Turning now to cash flow and balance sheet. The second quarter is a seasonably low quarter from a cash flow perspective. Net cash used in continuing operations was $48.5 million. Our capital expenditures for the quarter totaled $8.1 million. As a result, free cash flow used in the second quarter was $56.6 million. As a reminder, we define free cash flow as cash provided by continuing operations less capital expenditures. We ended the second quarter with cash and cash equivalents of $275.4 million and outstanding bank borrowings under our existing Term Loan B and secured -- senior secured notes of $1.65 billion.
Moving to our outlook for the remainder of fiscal 2022. Starting with the top line, we expect adjusted revenue to be within the range of $1.35 billion and $1.39 billion, and adjusted diluted earnings per share of $2.90 to $3.10 from continuing operations, excluding special items. Given the complexity and uncertainty of the markets we serve, it is important to understand the factors and assumptions we took into consideration when developing our guidance range.
Our full year guidance is impacted primarily by 2 factors: the move of our Financial Services segment to discontinued operations and the continued near-term headwinds from COVID, resulting in lower enrollments. The impact from COVID-related headwinds on our industry particularly those associated with the Omicron variant causing record spikes in cases and hospitalizations is expected to negatively affect enrollment, especially in our post-licensure nursing programs for the remainder of the fiscal year. While we expect these headwinds to subside over time, we believe there will be a lag in enrollment recovery within the health care education space as compared to the broader education industry.
Next, moving to the expected impact from the pending sale of our Financial Services segment. Net proceeds from the transaction are estimated to be in excess of $800 million. We expect the divestiture to be dilutive to adjusted earnings per share from continuing operations by approximately $0.90 on a full year basis, reflecting the loss of operating income and the retention of corporate overhead previously allocated to the segment. We continue to thoughtfully rationalize our corporate cost structure and drive operating efficiencies across our businesses while transitioning to our enhanced operating model. I also want to emphasize that this dilutive impact on EPS is prior to factoring in any benefit in future years from the use of net proceeds from the sale.
We are immensely excited about the optionality this transaction provides in enhancing our financial flexibility towards the deployment of the sale proceeds, and we'll provide more details upon closing. We remain highly encouraged in our ability to fully leverage our streamlined health care-focused portfolio with the twin goals of driving outstanding student outcomes and maximizing shareholder value.
With that, I will now turn the call over to the operator for Q&A.
