Translating clinical guidelines into practice: the effective and appropriate use of human growth hormone

Abstract

There are 9 recombinant human growth hormone (rhGH) products currently available for 10 US Food and Drug Administration-approved indications; each rhGH product is approved for 1 or more indications. Adult and pediatric patients with the various conditions for which rhGH is indicated, from idiopathic short stature (ISS) and growth hormone (GH) deficiency to short bowel syndrome and HIV/AIDS wasting, may benefit from rhGH treatment. In clinical practice, pediatric patients with GH deficiency or ISS make up the majority of the population receiving treatment with rhGH. Most rhGH products are provided through specialty pharmacies that often have to balance the needs of the patient, their own utilization objectives, and the availability of the rhGH on formulary from a particular payer. Often, a payer will prefer only 2 or 3 rhGH products to cover all 10 indications. As such, managed care professionals need to be more informed about the options available and should be familiar with the different indications to help educate patients about treatment. Additionally, healthcare providers should endeavor to identify and manage the care of appropriate patients who would potentially benefit from rhGH therapy, and should be aware of formulary options. Because many of the patients are children and young adults, adherence to treatment is a concern; patient education on the importance of treatment adherence should be ongoing. Various mechanisms are in place (eg, prior authorization requirements and case manager follow-up) to help ensure that rhGH products are used, and used appropriately. This publication includes highlights from a roundtable discussion by key opinion leaders (clinicians and managed care professionals) on how managed care policies and clinical guidelines on appropriate use of rhGH translate into real-world practice. Also discussed are the efficacy and safety of rhGH therapy for its pediatric indications, and the role of specialty pharmacies in managing patient access to therapy.
