We examined the impact of patient-level factors on provider recognition of posttraumatic stress disorder (PTSD). Analyses were based on a random sample of 1,079 consenting patients who had an outpatient visit at any of four southeastern Department of Veterans Affairs hospitals in 1999. We collected data on PTSD symptoms, sociodemographics, functional status, medical record diagnoses, and independent PTSD diagnostic assessments for 888 patients. Complete and usable data were available for 819 patients. A total of 98 patients (12%) met criteria for PTSD, and of these, 42 (43%) were correctly classified as such by their provider. Results indicate that age (50-64), war-zone service, worse functioning on the 36-Item Short Form Health Survey role emotional subscale, a diagnosis of musculoskeletal pain, a greater percentage of persistent reexperiencing or avoidance/numbing symptoms, and a previously diagnosed substance use disorder were all independently related to provider recognition of PTSD. Knowledge of these factors may help inform providers and direct improved screening and case finding.

This study compares a sample of urban men who have sex with men (MSM) with a general population sample of men in the same city on self-reported problems with substance use indicative of dependence and history of substance use treatment. Both samples were randomly selected using multistage probability methods. All participants completed audio computer-assisted self-interviews, including questions on substance use, problems related to substance use experienced in the past 12 months, and substance treatment. Problem use of alcohol, marijuana, and cocaine did not differ between samples. Compared to men in the general population sample, MSM were significantly more likely to experience problems related to the use of sedatives, tranquilizers, or prescription pain relievers. Among MSM, history of substance treatment was associated with a positive HIV test, and treatment usually preceded HIV diagnosis. Research is needed on effective methods for integrating HIV prevention for MSM into substance treatment settings, including physician-administered buprenorphine treatment for opiate addiction.

This study investigated the link between physical pain and non-medical prescription analgesic use (NMPAU), as well as the degree to which this association may vary by the presence of psychiatric and substance use disorders. Data were from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative, in-person probability sample of adults (n=43,093) aged 18 or older in the United States (2001-2002). Face-to-face interviews were used to gather information on past-year levels of physical pain (i.e., low, medium, high), in addition to DSM-IV classifications for mood, anxiety, substance use problems (i.e., abuse and/or dependence), and personality disorders. Within the analytic sample of those with valid data (n=42,734), the past-year rate of NMPAU was 1.8%, of which 20% met the DSM-IV criteria for abuse/dependence. Among past-year NMPAUs, 53% was incidental (e.g., less than monthly), but daily use was substantial (13% of NMPAUs). Accounting for our target confounding factors, pain was positively associated (p<0.05) with an increased probability of non-disordered (i.e., no abuse and/or dependence) and disordered (i.e., abuse and/or dependence) NMPAU in the past year. Within each level of pain, the odds of past-year non-disordered and disordered NMPAU were significantly higher (p<0.05) for those with disordered alcohol use compared with non-disordered users. This pattern was similar for illicit drugs, although marginally significant (p=0.060) and specific to disordered NMPAU. In contrast, psychiatric disorders increased the probability of both types of NMPAU, but these associations did not differ by levels of pain. These findings suggest that pain is an independent risk factor for non-disordered and disordered NMPAU, yet its effects are substantially modified by patterns of substance use.

HIV infection and substance use disorders are chronic diseases with complex contributions to health-related quality of life (HRQOL). We conducted a cross-sectional survey of 951 HIV-infected adults receiving care at 14 HIV Research Network sites in 2003 to estimate associations between HRQOL and specific substance use among HIV-infected patients. HRQOL was assessed by multi-item measures of physical and role functioning, general health, pain, energy, positive affect, anxiety, and depression. Mental and physical summary scales were developed by factor analysis. We used linear regression to estimate adjusted associations between HRQOL and current illicit use of marijuana, analgesics, heroin, amphetamines, cocaine, sedatives, inhalants, hazardous/binge alcohol, and drug use severity. Current illicit drug use was reported by 37% of subjects. Mental HRQOL was reduced for current users [adjusted beta coefficient -9.66, 95% confidence interval [(CI]) -13.4, -5.94] but not former users compared with never users. Amphetamines and sedatives were associated with large decreases in mental (amphetamines: beta = -22.8 [95% CI -33.5, -12.0], sedatives: beta = -18.6 [95% CI -26.2, -11.0]), and physical HRQOL (amphetamines: beta = -11.5 [95% CI -22.6, -0.43], sedatives: beta = -13.2 [95% CI -21.0, -5.36]). All illicit drugs were associated with decreased mental HRQOL: marijuana (beta = -7.72 [95% CI -12.0, -3.48]), non-prescription analgesics (beta = -13.4 [95% CI -20.8, -6.07]), cocaine (beta = -10.5 [95% CI -16.4, -4.67]), and inhalants (beta = -14.0 [95% CI -24.1, -3.83]). Facilitating sobriety for patients with attention to specific illicit drugs represents an important avenue for elevating HRQOL in patients living with HIV.

Wars in Afghanistan and Iraq have resulted in thousands of military personnel suffering traumatic brain injury (TBI), including closed-head injuries. Of interest is whether these individuals and other TBI survivors are at increased risk for substance use disorder (SUD). While it has been well established that drug or alcohol intoxication itself increases probability of suffering a TBI in accidents or acts of violence, little is known about whether the brain insult itself increases the likelihood that a previously non-drug-abusing individual would develop SUD. Might TBI survivors be unusually vulnerable to addiction to opiate analgesics compared to other pain patients? Similarly, it is not known if TBI increases the likelihood of relapse among persons with SUD in remission. We highlight challenges in answering these questions, and review neurochemical and behavioral evidence that supports a causal relationship between TBI and SUD. In this review, we conclude that little is known regarding the directionality of TBI increasing drug abuse, and that collaborative research in this area is critically needed.

This study used three characteristics (i.e., motive, route of administration, and co-ingestion with alcohol) of nonmedical prescription drug misuse across four separate classes (i.e., pain, sedative/anxiety, sleeping, and stimulant medications) to examine subtypes and drug related problems. A Web survey was self-administered by a randomly selected sample of 3639 undergraduate students attending a large midwestern 4-year U.S. university. Self-treatment subtypes were characterized by motives consistent with the prescription drug's pharmaceutical main indication, oral only routes of administration, and no co-ingestion with alcohol. Recreational subtypes were characterized by recreational motives, oral or non-oral routes, and co-ingestion. Mixed subtypes consisted of other combinations of motives, routes, and co-ingestion. Among those who reported nonmedical prescription drug misuse, approximately 13% were classified into the recreational subtype, while 39% were in the self-treatment subtype, and 48% were in the mixed subtype. There were significant differences in the subtypes in terms of gender, race and prescription drug class. Approximately 50% of those in subtypes other than self-treatment screened positive for drug abuse. The odds of substance use and abuse were generally lower among self-treatment subtypes than other subtypes. The findings indicate subtypes should be considered when examining nonmedical prescription drug misuse, especially for pain medication.

Few studies have investigated the association between the social context of cannabis use and cannabis use disorder (CUD). This longitudinal study of college students aimed to: develop a social context measure of cannabis use; examine the degree to which social context is associated with the transition from non-problematic cannabis use to CUD; and, examine the association between social context of cannabis use and depressive symptoms. The analytic sample consisted of 322 past-year cannabis users at baseline. Four distinct and internally consistent social context scales were found (i.e., social facilitation, emotional pain, sex seeking, and peer acceptance). Persistent CUD (meeting DSM-IV criteria for CUD at baseline and 12 months later) was associated with using cannabis in social facilitation or emotional pain contexts, controlling for frequency of cannabis use and alcohol use quantity. Students with higher levels of depressive symptoms were more likely to use cannabis in an emotional pain or sex-seeking context. These findings highlight the importance of examining the social contextual factors relating to substance use among college students.

Long-term opioid therapy for non-cancer pain has increased. Caution is advised in prescribing for persons with substance use disorders, but little is known about actual health plan practices. This paper reports trends and characteristics of long-term opioid use in persons with non-cancer pain and a substance abuse history. Using health plan data (1997-2005), the study compared age-sex-standardized rates of incident, incident long-term and prevalent long-term prescription opioid use, and medication use profiles in those with and without substance use disorder histories. The CONsortium to Study Opioid Risks and Trends study included adult enrollees of two health plans, Kaiser Permanente of Northern California (KPNC) and Group Health Cooperative (GH) of Seattle, Washington. At KPNC (1999-2005), prevalence of long-term use increased from 11.6% to 17.0% for those with substance use disorder histories and from 2.6% to 3.9% for those without substance use disorder histories. Respective GH rates (1997-2005), increased from 7.6% to 18.6% and from 2.7% to 4.2%. Among persons with an opioid disorder, KPNC rates increased from 44.1% to 51.1%, and GH rates increased from 15.7% to 52.4%. Long-term opioid users with a prior substance abuse diagnosis received higher dosage levels, were more likely to use Schedule II and long-acting opioids, and were more often frequent users of sedative-hypnotic medications in addition to their opioid use. Since these patients are viewed as higher risk, the increased use of long-term opioid therapy suggests the importance of improved understanding of the benefits and risks of opioid therapy among persons with a history of substance abuse, and the need for more careful screening for substance abuse history than is the usual practice.

When prescribed appropriately and used as prescribed, opioid medications can safely and effectively treat pain. Best practices with respect to their use in chronic non-cancer-related pain (CNCP) are evolving. Opioids may be subject to misuse for a variety of purposes, including self-medication, use for reward, compulsive use because of addiction, and diversion for profit. Individuals with chronic pain and co-occurring substance use, mental health disorders, and other conditions may be at increased risk for misuse of prescribed opioids. Interdisciplinary pain management, the use of universal precautions in all patients, and special attention to the structure of care in those at higher risk for opioid misuse may improve outcomes in opioid treatment of CNCP. This article discusses evolving research and clinical literature related to the care of individuals with CNCP at a higher risk for opioid misuse.

General hospital clinicians frequently deal with injecting drug users because substance use has diverse medical and psychiatric complications. Non-specialist clinicians often initiate management when specialist consultation is not available or accepted by the patient. Here, we summarise evidence for the management of hospitalised injecting drug users. The first challenge is to engage a drug user into medical care. A non-judgmental approach towards patients and acceptance of their lifestyle choices facilitates engagement. Pragmatic clinical goals can be negotiated and achieved. We also describe common conditions of injecting drug users. Accurate diagnosis and appropriate management focus on common issues such as intoxication, withdrawal, pain management, drug seeking, psychological comorbidity, behavioural difficulties, and pregnancy. Effective management can reduce the medical and social effect of these conditions and is not difficult.
