In the 1970s, the average lifespan for patients diagnosed with sickle cell disease was 14 years. Today, the average lifespan has increased to 50 years and beyond (TriHealth, 2012). The patient prognosis for many other hematologic disorders such as hemophilia and cancer continue to improve as well. This can be attributed to advancements in medical care—specifically drug therapy and treatment. When managing drug therapies for patients, it is essential to continuously examine current treatments and evaluate the impact of patient factors on drug effectiveness. To prepare for your role as an advanced practice nurse, you must become familiar with common drug treatments for various hematologic disorders seen in clinical settings.
