A primer on definitive gas and liquid chromatography drug testing: What clinicians need to know.
To describe the differences between mass spectrometry technologies and compare and contrast them with immunoassay techniques of urine drug testing (UDT). Highlight the potential importance of the differences among these technologies for clinicians so as to allow them make decisions in their use in patient care. ⋯ UDT is an important clinical tool, though there are differences in technology and testing processes with important implications for clinical decision making. It is crucial, therefore, that clinicians have an understanding of the technologies behind the tests they order, so that their interpretation and use of results are based on an understanding of the strengths and weaknesses of the technologies used.

Prescription opioid analgesics with a wide range of potencies are currently used for the treatment of chronic pain. Yet understanding the clinical relevance and therapeutic consequences of opioid potency remains ill defined. Both patients and clinicians alike have misperceptions about opioid potency, expecting that less-potent opioids will be less effective or fearing that more-potent opioids are more dangerous or more likely to be abused. ⋯ Differences in pharmacologic potency are largely accounted for by the actual doses prescribed, according to individualized patient need. Factors for achieving effective analgesia and reducing the risks involved with opioid use include careful medication selection based on patient characteristics, appropriate dosing titration and opioid rotation practices, knowledge of product formulation characteristics (eg, extended release, immediate release, and tamper-resistant features), and an awareness of differences in opioid pharmacokinetics and metabolism. Clinicians should remain vigilant in monitoring patients on any opioid medication, regardless of classification along the opioid potency continuum.

Buprenorphine is approved by the Food and Drug Administration for the treatment of chronic pain in low-dose transdermal patch formulations and for the treatment of addiction in high-dose sublingual tablets and films. Clinicians often prescribe these high-dose preparations "off label" for pain management. In the workers' compensation setting, it is particularly important to consider factors such as a) if the injured person has, and is being treated for co-occurring addiction as well as pain; b) if alternative therapies, including opioid withdrawal, were considered prior to initiating buprenorphine treatment; and c) the anticipated duration of treatment. This article reviews buprenorphine's approved indications, formulations, pharmacology, clinical efficacy, and special considerations in the workers' compensation setting.

Pain management in patients with cancer remains suboptimal. Breakthrough pain (BTP) is characterized by abrupt onset of severe pain in a background of otherwise stable managed pain and presents a substantial burden to patients, as it disrupts activities and quality of life. Rapid-onset opioids (ROOs), with an appropriate onset and duration of effect, provide new options for effective and well-tolerated management of BTP. ⋯ Rapid onset and short duration of action allow good patient control of analgesia. The pharmacokinetic and analgesic properties of ROOs may allow reduction of the total opioid burden and associated adverse effects, while still providing effective pain relief. The shared TIRF risk evaluation and mitigation strategy program implemented in March 2012 has simplified enrollment and administration of these products to help mitigate the risks of abuse and misuse and to help ensure safe use in patients with cancer suffering from BTP.
