All patients with pain have a level of risk that can only be roughly estimated initially and modified over time as more information is obtained. There are ten essential steps of opioid prescribing for chronic pain to help mitigate any potential problems [5]:

When implementing a chronic pain treatment plan that involves the use of opioids, the patient should be frequently reassessed for changes in pain origin, health, and function [4]. This can include input from family members and/or the state prescription drug monitoring program. Prescription drug monitoring programs are one of the most effective measures for reducing opioid analgesic diversion and abuse, but their efficacy is undermined by inconsistent use [6]. During the initiation phase and during any changes to the dosage or agent used, patient contact should be increased. Decisions regarding the continuation, modification, or termination of opioid therapy for pain should be based on evaluation of the patient's progress and the absence of substantial risks or adverse events [4]. At every visit, chronic opioid response may be monitored according to the 5 A's [8]:

The Current Opioid Misuse Measure (COMM) is a 17-item patient self-report assessment designed to help clinicians identify misuse or abuse in patients with chronic pain. Unlike the ORT and the SOAPP-R, the COMM identifies aberrant behaviors associated with opioid misuse in patients already receiving long-term opioid therapy [11]. Sample questions include: In the past 30 days, how often have you had to take more of your medication than prescribed? In the past 30 days, how much of your time was spent thinking about opioid medications (e.g., having enough, taking them, dosing schedule)?

Guidelines by the FSMB and the Joint Commission stress the importance of documentation from both a healthcare quality and medicolegal perspective. Research has found widespread deficits in chart notes and progress documentation with patients with chronic pain receiving opioid therapy, and the Pain Assessment and Documentation Tool (PADT) was designed to address these shortcomings [12]. The PADT is a clinician-directed interview, with most sections (e.g., analgesia, activities of daily living, adverse events) consisting of questions asked of the patient. However, the potential aberrant drug-related behavior section must be completed by the physician based on his or her observations of the patient.

Family members of the patient can provide valuable information that better informs decision making regarding continuing opioid therapy. Family members can observe whether a patient is losing control of his or her life or becoming less functional or more depressed during the course of opioid therapy. They can also provide input regarding positive or negative changes in patient function, attitude, and level of comfort. The following questions can be asked of family members or a spouse to help clarify whether the patient's response to opioid therapy is favorable or unfavorable [8]:

Initially, testing involves the use of class-specific immunoassay drug panels [4]. If necessary, this may be followed with gas chromatography/mass spectrometry for specific drug or metabolite detection. It is important that testing identifies the specific drug rather than the drug class, and the prescribed opioid should be included in the screen. Any abnormalities should be confirmed with a laboratory toxicologist or clinical pathologist. Immunoassay may be used point-of-care for "on-the-spot" therapy changes, but the high error rate prevents its use in major clinical decisions unless liquid chromatography is coupled with mass spectrometry confirmation.

Urine test results suggesting opioid misuse should be discussed with the patient using a positive, supportive approach. The test results and the patient discussion should be documented.

It is important to appreciate the limitations of UDTs. Healthcare providers are increasingly relying on UDTs as a means to reduce abuse and diversion of prescribed opioids. This has led to a proliferation in diagnostic laboratories that offer urine testing. With this increase have come questions of whether these business interests benefit or hinder patient care, what prescribers should do with the information they obtain, the accuracy of urine screens, and whether some companies and clinicians are financially exploiting the UDT boom [18]. Despite wide endorsement and making intuitive sense, there is little empirical confirmation that UDTs reduce prescription opioid abuse [1,6].

When prescribing opioids, clinicians should provide patients with the following information and instructions [7,26]:

There are no universal recommendations for the proper disposal of unused opioids, and patients are rarely advised of what to do with unused or expired medications. According to the Office of National Drug Control Policy, most medications that are no longer necessary or have expired should be removed from their containers, mixed with undesirable substances (e.g., cat litter, used coffee grounds), and put into an impermeable, nondescript container (e.g., disposable container with a lid or a sealed bag) before throwing in the trash [27]. The FDA recommends that most opioid medications, including oxycodone/acetaminophen (Percocet), oxycodone (OxyContin tablets), and transdermal fentanyl (Duragesic Transdermal System), be flushed down the toilet instead of thrown in the trash [27]. Disposal by flushing down the toilet provides immediate and definitive elimination of safety hazards from intentional use or accidental exposure involving opioid products. All transdermal patch opioid products should be flushed down the toilet after folding in half by adhesive side against adhesive side [28]. Patients should be advised to flush prescription drugs down the toilet only if the label or accompanying patient information specifically instructs doing so. Flushing unused medications has been the subject of controversy, with some state governments and boards recommending against the practice due to pollution concerns and effects on waterways and wildlife [29].

The decision to continue or end opioid prescribing should be based on a joint discussion of the anticipated benefits and risks. An opioid should be discontinued with resolution of the pain condition, intolerable side effects, inadequate analgesia, lack of improvement in quality of life despite dose titration, deteriorating function, or significant aberrant medication use [4].
