Decision-making capacity is a common reason for psychiatric consultation that is likely to become more common as the population ages. Capacity assessments are frequently compromised by misconceptions, such as the belief that incapacity is permanent or that patients with dementia categorically lack capacity. This chapter will review the conceptual framework of decision-making capacity and discuss its application to medical decision-making. ⋯ We will discuss clinical and legal approaches to incapacity, including advance directives, surrogate decision-makers, and guardians. We will discuss the legal standards based on which surrogates make medical decisions and outline options for resolving disagreements between clinical staff and surrogate decision-makers. We will offer recommendations for approaching decision-making capacity assessments.

Somatic symptoms are a common presentation of mental disorders or psychological distress worldwide, and may often coexist with depressive and anxiety symptoms, thus accounting for what might be the most frequent psychiatric syndrome in primary care. Indeed, physical symptoms accompanying the clinical presentations of a variety of mental disorders may be considered as universal 'idioms of distress' that may vary across cultures, depending on attitudes and explanations embedded in each one of them. These variations in symptom presentations are the result of various interacting factors that ultimately determine how individuals identify and classify bodily sensations, perceive illness, and seek medical attention. ⋯ Particular attention is paid to the association of somatic symptoms with mood symptoms, since depressive disorders appear to be the most common, costly and disabling psychiatric entities worldwide. The review shows that racial/ethnic variations in somatic symptoms in the context of depression are common, and seem to be related to depression severity. Sociocultural factors, particularly stigma, may influence the unique emphasis placed on somatic symptoms within depression, and may account for some racial/ethnic differences in somatic symptom reporting.

Habits relevant to health include physical activities, diet, smoking, drinking and drug consumption. Despite the fact that benefits of modifying lifestyle are increasingly demonstrated in clinical and general populations, assessment of lifestyle and therapeutic lifestyle changes is neglected in practice. In this review, associations between unhealthy lifestyle and health outcomes are presented. Particular emphasis will be placed on description and discussion of the standardized assessment instruments and behavioral methods that could be used in clinical practice to measure lifestyles.

As opioid prescribing has dramatically expanded over the past decade, so too has the problem of prescription drug abuse. In response to these now two major public health problems - the problem of poorly treated chronic pain and the problem of opioid abuse - a new paradigm has arisen in pain management, namely risk stratification. Once a prescriber has determined that opioids will be used (a medical decision based on how intense the pain is, what has been tried and failed and, to some extent, what type of pain the patient has), he/she must then decide how opioid therapy is to be delivered. ⋯ Recently, researchers have produced a wide variety of literature regarding assessment tools to be used for this purpose. And while there remains a need for larger prospective studies to examine the ability of each tool to predict aberrant drug-taking behaviors, clinicians can and should utilize one or more of these screening tools and understand their benefits and limitations. This chapter will describe the nature of current screening assessments, their potential for use in the pain population in various settings, past clinical observations and suggestions for moving forward.

Chronic opioid therapy for patients with chronic noncancer pain has become controversial, given the rising prevalence of opioid abuse. The prevailing literature suggests that the rate of addiction in chronic noncancer pain patients exposed to opioid therapy is relatively low, especially in those patients without significant concomitant psychiatric disorders and personal and family history of addiction. However, the escalating rate of misuse of prescription opioids has resulted in many clinicians caring for these patients to be more judicious in prescribing opioids. ⋯ Managing the patient with pain and co-occurring opioid abuse is equally challenging. Diagnostic issues, current guidelines for the appropriate use of opioids in the chronic pain population and risk stratification models are examined. Pharmacologic and nonpharmacologic treatment strategies for the patient with pain and opioid addiction are reviewed.
