I had a lift installed in my van because my wife is unable to walk on her own and I need to get her wheelchair in and out. Can I deduct the cost?

The cost of adaptive equipment for a medical condition is a deductible expense. However, you must itemize and your total medical costs must exceed your applicable threshold (10% of adjusted gross income, or 7.5% of adjusted gross income if you or your spouse is at least 65 years old by the end of the year).
