Due to successful use of intrathecal drug delivery in the management of refractory pain and spasticity, new agents and indications are now being investigated. Preclinical studies of neurotrophic factors, molecules necessary for neuroneal survival and development, suggest that these agents may be beneficial for patients with neurologic disorders. ⋯ Treatment of other neurologic disorders, such as brain tumors and HIV-related viral infections, also may be optimized by methods of local drug delivery, including intratumoral and intraparenchymal administration of potentially effective agents. Intraspinal, intratumoral, and intraparenchymal routes of administration are speculated to become critical components of treatment for a variety of neurological indications.

Intrathecal drug delivery is effective for the treatment of cancer and nonmalignant pain in patients who do not respond well to oral opioids, in patients who cannot tolerate the side effects associated with opioids, or in patients who show a large, permanent increase in dosage. Although intrathecal drug delivery is associated with pharmacological side effects and complications, its benefits far outweigh its risks. There are three main categories of potential adverse events associated with intrathecal drug delivery: pharmacologic side effects, surgical complications, and device-related complications. ⋯ Many adverse events either resolve on their own or can be managed with dosage or device adjustment. More serious complications may require surgical intervention or discontinuation of therapy. This paper will provide an overview of adverse events and complications, their origins, detection, manifestations, and management.

Successful management of chronic cancer and nonmalignant pain remains a challenge to clinicians, and cost effectiveness is an important consideration for clinical decision making. Although the oral route was previously considered the optimal method of chronic opioid administration, emerging evidence demonstrates a therapeutic advantage to intrathecal opioid delivery compared to alternative modalities. ⋯ Although the initial costs of surgical implantation of an intrathecal pump appear to be substantial, maintenance costs of intrathecal drug delivery over time are significantly lower than other routes of administration, including oral and intravenous drug delivery. Cost analyses of alternate routes of opioid administration indicate that intrathecal delivery is the most cost-effective route of opioid administration for patients who require long-term management of cancer (≥ 3-6 months) or nonmalignant pain (≥ 11-22 months).

Nationally, the focus on facilities providing effective pain management has increased, yet no funds have been allocated to pain management programs. The article describes a 3-year study whose purpose was to evaluate the effect on nurses' attitudes and behavior of the institution of a multifaceted, low-cost hospital pain management program. ⋯ Nurses were surveyed before and after the pain management program using the 39-item Nurses' Knowledge and Attitudes Survey. Results demonstrated a statistically significant increase between pretest and posttest scores.
