    Patient screening tools

    The U.S. Preventative Services Task Force reported insufficient evidence to recommend screening for substance use disorders other than alcohol, but some have suggested that universal screening may be justified based on the associated prevalence, morbidities, and comorbidities (anxiety, depression, bipolar disorder, post-traumatic stress disorder, personality disorders, and intimate partner violence) of substance abuse.5

    The National Institute on Drug Abuse recommends screening patients in general medical settings for drug use, including tobacco, alcohol, illicit drugs, and nonmedical use of prescription drugs via the “5 As of Intervention:” Ask (screening), Advise (strong direct personal advice), Assess (determine willingness to change behavior after advice), Assist (help), and Arrange (refer for further assessment, treatment, follow-up).12

    Additional quick screening tools include a single-question screen (“How many times in the past year have you used an illegal drug or used a prescription drug for nonmedical reasons?”), the Drug Abuse Screening Test-10, and the AUDIT, AUDIT-C, and CAGE-AID questionnaires.5,13

    Direct confrontation is seldom helpful when treating patients with possible substance abuse disorders. Improve outcomes with motivational interviewing techniques such as resisting the “righting reflex,” listening, using a non-confrontational approach so to advise or share information while allowing patients to express feelings about change (“elicit-provide-elicit”), articulating the pros and cons of change (decision analysis), identifying statements patients make in support of change and reflecting such statements back (reflections), and promoting patient self-efficacy to improve confidence in making change (affirmations).5

    Once ODs identify substance misuse, refer to primary care physicians with training and experience or to specialty addiction treatment. Additional resources for the patient and the referring doctor may include mutual help meetings (such as Alcoholics Anonymous, Narcotics Anonymous, Rational Recovery, SMART Recovery), medically supervised withdrawal, and outpatient or residential treatment (such as American Society of Addiction Medicine Physician Finder, Substance Abuse and Mental Health Services Administration Treatment Locator).

    Impaired patients in the office

    Acutely impaired patients presenting to the office represent a dilemma for staff and doctors. These patients may intend to drive while impaired by alcohol, illicit drugs, or prescribed medications. This situation represents significant risk of injury and death via motor vehicle accident as well as liability to the practice and doctor.

    The ethical dilemma places the duty to prevent harm to the patient and others vs. the need to respect the patient’s rights of autonomy and confidentiality.

    Legal problems may develop based upon the varied federal, state, and case law regarding breach of confidentiality, the duty to warn, and the duty to report. The Health Insurance Portability and Accountability Act (HIPPA) permits disclosure of relevant protected health information to family members or law enforcement when the provider believes the patient represents a “serious and imminent threat” to self or others.14

    Most state jurisdictions do not specifically address how to handle patients representing danger to others due to current intoxication with regard to confidentiality, but case law indicates that a healthcare provider should minimally inform the impaired patient not to drive.15 Suitable alternatives might include having the patient arrange for a sober friend or relative to drive or calling a taxi  or ride-sharing service such as Uber or Lyft.

    Decrease your liability risk by documenting the warning to not drive and making reasonable efforts to arrange transportation. In the event of the patient becoming abusive, threatening, or driving while a risk to self and others, it’s reasonable to notify the police.

    Because these situations can be expected to occur over the course of a career, consider implementing a written office policy for staff regarding how to manage impaired patients. Suggestions for office policies include: detailed and complete documentation of the incident (this may be kept separate from the patient chart), approaching the patient in a non-confrontational manner, expressing concern regarding driving, offering to find alternative transportation, calling the police if necessary, and confirming coverage with the practice general liability insurer for any potential related problems.16

    Optometry’s larger role in health care

    Optometry has integrated and embraced many of the 10 Cs of primary care17 as important aspects of our profession. Our Optometric Code of Ethics charges us to keep the patients’ general health paramount, to advise patients whenever consultation with or referral to another healthcare professional is appropriate, to recognize our obligation to protect the health and welfare of society, and to conduct ourselves with compassion.18

    The significant healthcare dilemmas of substance use and SUDs pose challenges to our society. As doctors seeing these patients in multiple settings and interacting with other professionals and within interprofessional teams, optometrists have an opportunity to demonstrate an 11th C: compassion.
