Opioid Prescribing Part 1: A Practical Guide to Appropriate Documentation
Pain is one of the most common reasons patients visit a health care professional. Professionals spend a great deal of time learning how to diagnose and treat pain-related medical problems but much less time learning how to document the process. Traditionally, documentation by physicians has been minimal—just enough information was scribbled in the chart so that the diagnosis, medications prescribed, procedures done, and referrals were recorded.
With the advent of electronic health records (EHRs), documentation is more detailed but often consists primarily of checking appropriate boxes. Although inadequate documentation rarely is a cause for regulatory scrutiny in patients with hypertension, diabetes, chronic obstructive pulmonary disease, etc., it is a very common reason for medical board discipline when it comes to treatment of chronic pain patients with opioids. Even if a physician is caring, knows his or her patient well, asks the right questions, is satisfied with the patient’s answers, and concludes that the patient is benefiting from the medications and is not abusing them—if this information is not documented in the chart, from a medicolegal perspective, it didn’t happen.
In this first part of a 2-part series, I will address appropriate documentation for opioid prescribing, and in Part 2,
I will outline appropriate follow-up documentation of patients with chronic pain taking opioids.
Documentation Guidelines: Initial Visit
Guidelines for the use of opioids for pain and their documentation are widely available.1-5 Any clinician who prescribes opioids or other controlled substances for chronic pain must read and be familiar with the Federation of State Medical Boards Model Policy for the Use of Controlled Substances for the Treatment of Pain.2 This document has formed the basis for many of the individual state guidelines. It summarizes both the necessary elements of the initial work-up and follow-up of chronic pain patients, as well as the necessary elements of documentation of these actions (Table).
On the first visit, the record should include information about the history of the problem, the type and intensity of the pain, results of previous diagnostic studies, and treatments. If this is an ongoing problem, you need to know (and document) what medications were tried in the past, including doses and duration, and if a medication was stopped, the reason. You need specific information about past treatments to better determine how to treat the patient. He or she may be unable to provide this information as thoroughly as you need, which is why it is essential to request old records. The patient needs to sign a release that includes contact information for prior relevant physicians. The signed release belongs in the chart, and it is useful to give a copy to the patient to review at home. On follow-up visits, you need to check whether you received the old records. If not, look into this and document your ongoing efforts to obtain the old records. When they arrive, the physician needs to actually review the old records rather than just initialing and filing them. They may contain useful information not only about the patient’s pain problem but also about psychosocial factors and issues of compliance.
Especially on the first visit, the record should give you a picture not only of the specific problem, but also an overall view of the patient. This includes their medical history and current physical functioning as well as their psychological and social circumstances. Are they able to drive? Are they employed—if so, what do they do? How’s their sleep? Do they live alone? Do they have a family? Chronic pain often is associated with depression, so ask about depression, anxiety, and other psychiatric problems. It also is important to assess their risk for drug abuse or diversion. This includes asking about their personal and family history of cigarette, drug, and alcohol use, and current use of these substances. The patient also needs to fill out one of the several available risk assessment tools such as Opioid Risk Tool6 or Screener and Opioid Assessment for Patients with Pain (SOAPP).7 Document the results of these surveys.
Baseline Urine Drug Screen
If the patient already is being prescribed opioids, or if you are considering opioids as part of the treatment plan, it is wise to obtain a baseline urine drug screen (UDS). If the patient reports current use of any opioid, benzodiazepine, or other controlled drugs, ask him when the last dose of each medication was taken, and document the date and time he or she reports. When evaluating the results of a UDS, it is essential to have this information on record; if the last dose was taken at least 5 half-lives before the timing of the UDS, a negative result for the drug is to be expected and is not necessarily a reflection of diversion. This is particularly important when the opioid in question is prescribed prn (as needed) and indeed is being used intermittently.
Whenever a UDS is ordered, you or your assistant should document the time of the last dose of each drug. You should review the results of the UDS and document your thinking and action on any unexpected result. If it is not clear whether an unexpected drug in the urine could be a legitimate metabolite of a prescribed drug (ie, actually an expected finding), call the clinical laboratory and discuss the result with their toxicologist. For example, a patient on oxycodone can be expected to also have oxymorphone in the urine; hydrocodone is metabolized to hydromorphine; and codeine is metabolized to morphine. For each pairing, both are expected in the urine. There are several references that provide helpful information regarding UDSs.4,8-10
Prescription Monitoring Program
Another useful tool, now provided by most states in the US, is the state’s Prescription Monitoring Program (PMP), an updated list of all controlled substances prescribed to each patient in that state, accessible to prescribers and other categories of professionals (varies by state). Health care professionals no longer need to depend on pharmacists to find out whether a patient is obtaining opioids and other scheduled drugs from multiple providers—it is all on your state’s prescription monitoring website. Document in the patient’s chart that you have checked the patient’s history on the website and whether there are any results of concern. (Efforts are in progress for states to share their PMP websites so that it will be possible to see what prescriptions are being obtained in other states; this can be useful especially in communities that border on more than one state.)
