Comparative Study Clinical Trial Controlled Clinical Trial
Does postoperative pain induce emesis?
The aim of this prospective, controlled study was to evaluate the risk factors for postoperative emesis in patients undergoing gynecologic surgery and receiving patient-controlled analgesia for three days. ⋯ The results suggested that postoperative pain was an associative risk factor to increase the incidence of emesis in these female patients.

Comparative Study
Abuse and addiction issues in medically ill patients with pain: attempts at clarification of terms and empirical study.
The assessment of addiction-related outcomes is crucial to the management of chronic pain with opioid drugs in all patients. Pain management for patients who have concomitant drug abuse or addiction issues is a particularly complex task involving a need for a common nomenclature as well as empirically derived data to support management strategies during treatment regimens. Complicating the issue is the notion of pseudoaddiction, which is an abuse of medications driven by unrelieved pain that appears on the surface to be very similar to the behavior patterns of addicts. ⋯ What is ultimately needed is a broad-based spectrum of research that highlights the epidemiology of drug-taking behaviors for different medical illnesses ranging from cancer to back pain. This article focuses on some of these issues as well as recounting attempts by our research group to address these issues systematically in hopes of shedding light on the nature of abuse issues in the medically ill. Although advances have been made, there is a definite need for large-scale studies that address the issues of identification and treatment of aberrant behavior in medically ill patients in the effort to provide the best possible outcomes for patients with chronic pain.

Patients may present to physicians with complaints of acute or chronic pain. Some of these patients will have a history of addiction to drugs or alcohol, and a few will have active addiction. Controlled-substance prescriptions, especially opioid pain medications, can be very beneficial for treatment of pain in patients. ⋯ General guidelines can improve physicians' comfort level in prescribing opioids for patients with chronic pain, even those with a history of addiction. These include using a medication agreement or contract, setting appropriate goals with the patient, giving appropriate amounts of pain medication, monitoring with drug screens and pill counts, and documenting the case carefully. Even patients with a history of addiction can benefit from opioid pain medications if the patients are monitored appropriately.

Review
Assessment of efficacy of long-term opioid therapy in pain patients with substance abuse potential.
Clinical experience supports the notion that opioids can be used successfully to treat many chronic pain conditions. Unfortunately, few controlled trials have assessed which individuals benefit from long-term opioid therapy, and there is concern about the use of long-term opioid therapy in individuals with a substance-abuse history. This article contains three sections relevant to the assessment of individuals with chronic pain and a substance-abuse history who are receiving long-term opioid therapy. ⋯ The third reviews areas critical in assessing treatment efficacy and substance abuse in patients with chronic pain, both in terms of documentation of past behaviors and as a measure of outcome of opioid therapy. Potential guidelines for use of opioids in patients with chronic noncancer pain are outlined. Finally, questions are posed for future investigations of the efficacy of opioid therapy for patients with chronic pain and a substance-abuse history.

Undertreatment of pain is likely to occur among patients with active addiction or those who have a history of addiction. One of the factors that can contribute to the inadequate treatment of pain in this patient population is the presence of laws and regulations that, when implemented, could impede effective pain management. ⋯ Three types of policy barriers are discussed: (1) those that can affect pain management in any patient, (2) those that can lead to patients in pain being classified as "addicts," and (3) those that relate specifically to patients with a high risk of addiction. Also presented are recent policy initiatives that can improve the use of controlled substances to treat pain and, thus, ultimately enhance pain relief for patients with an addictive disease.
