Screening for sexually transmitted infections in substance abuse treatment programs.

OBJECTIVES: We evaluated the prevalence of the sexually transmitted infections (STIs) chlamydia and gonorrhea in clients at a methadone maintenance program and a residential detoxification program. METHODS: We collected urine specimens for chlamydia and gonorrhea ligase chain reaction testing and assessed sexual, substance abuse and STI histories. RESULTS: Of 700 subject assessments, 490 occurred among detoxification clients and 210 in methadone maintenance. Chlamydia trachomatis was detected in 5/700 (0.9, 95% CI=0.1-1.8%) and Neisseria gonorrhoeae in none. All chlamydia infected subjects were recruited from the detoxification program. Subjects reported high risk sexual behavior: 17% reported commercial sex exchange, and 22% reported inconsistent condom use with multiple sexual partners during the prior 2 months. CONCLUSION: Based on prevalence in Boston, MA, universal screening for STI in substance abuse treatments programs is not warranted. However, routine screening for younger substance abusers and in communities with high prevalence should be considered.

Addressing alcohol problems in primary care: a cluster randomized, controlled trial of a systems intervention. The screening and intervention in primary care (SIP) study.

BACKGROUND: Screening and intervention for alcohol problems can reduce drinking and its consequences but are often not implemented. OBJECTIVE: To test whether providing physicians with patients' alcohol screening results and simple individualized recommendations would affect the likelihood of a physician's having a discussion with patients about alcohol during a primary care visit and would affect subsequent alcohol use. DESIGN: Cluster randomized, controlled trial. SETTING: Urban academic primary care practice. PARTICIPANTS: 41 faculty and resident primary care physicians and 312 patients with hazardous drinking. INTERVENTIONS: Providing physicians with alcohol screening results (CAGE questionnaire responses, alcohol consumption, and readiness to change) and recommendations for their patients at a visit. MEASUREMENTS: Patient self-report of discussions about alcohol use immediately after the physician visit and alcohol use 6 months later. RESULTS: Of 312 patients, 240 visited faculty physicians, 301 (97%) completed the outcome assessment after the office visit, and 236 (76%) were followed for 6 months. Faculty physicians in the intervention group tended to be more likely than faculty physicians in the control group to give patients advice about drinking (adjusted proportion, 64% [95% CI, 47% to 79%] vs. 42% [CI, 33% to 53%]) and to discuss problems associated with alcohol use (74% [CI, 59% to 85%] vs. 51% [CI, 39% to 62%]). Resident physicians' advice and discussions did not differ between groups. Six months later, patients who saw resident physicians in the intervention group had fewer drinks per drinking day (adjusted mean number of drinks, 3.8 [CI, 1.9 to 5.7] versus 11.6 [CI, 5.4 to 17.7]). CONCLUSIONS: Although effects seem to differ by physician level of training, prompting physicians with alcohol screening results and recommendations for action can modestly increase discussions about alcohol use and advice to patients and may decrease alcohol consumption.

Slowing the revolving door: stabilization programs reduce homeless persons' substance use after detoxification.

This study examined whether homelessness predicted earlier resumption of substance use after detoxification, and sought evidence concerning the impact of post-detoxification stabilization programs among homeless and nonhomeless individuals. Kaplan-Meier plots and proportional hazards models were used to determine the association between homelessness, stabilization program use, and recurrent substance use in a prospective cohort of persons entering inpatient detoxification (n=470). Among 254 persons available at 6 months, 76% reported recurrent substance use. Homeless persons not using stabilization programs experienced the highest hazard of return to substance use after detoxification, Hazard Ratio (HR) 1.26, 95% CI (0.88, 1.80). Homeless persons using these programs had the lowest rate of return to substance use: HR 0.61, 95% CI (0.40, 0.94). A similar impact of stabilization programs was not seen among nonhomeless subjects. Post-detoxification stabilization programs were associated with improved outcomes for homeless addicted persons. This treatment modality may slow the "revolving door" phenomenon of relapse after detoxification among homeless persons.

Substance abuse treatment and emergency department utilization among a cohort of HIV-infected persons with alcohol problems.

We examined the association between substance abuse treatment services and emergency department (ED) utilization among participants in the HIV-Alcohol Longitudinal Cohort study of HIV-infected persons with a history of alcohol problems. A standardized questionnaire was administered to 350 subjects inquiring about demographics, substance use, use of substance abuse treatment services, and ED attendance. We operationally defined substance abuse treatment services as: stable, unstable, or none. The outcome, ED attendance, defined as presenting to an ED without subsequent hospitalization, occurred in 101 (28.8%) subjects in the past 6 months. Stable substance abuse treatment was significantly associated with lower odds of ED attendance (adjusted odds ratio; 95% CI): (0.5; 0.3-0.9). The relationship between substance abuse treatment and HIV-infected individuals' use of health care services merits additional attention. Substance abuse treatment may present an opportunity to impact health care utilization patterns of HIV-infected persons with a history of alcohol problems.

Education of preventive medicine residents: alcohol, tobacco, and other drug abuse.

BACKGROUND: Generalist physicians' addiction training is inadequate, but general preventive medicine residency (PMR) programs have not been studied. We determined PMR programs' alcohol, tobacco, and other drug abuse (ATOD) training from 1995 to 2000 and identified barriers to this education. METHODS: Interviewer-administered telephone survey of program directors (PDs) of accredited PMR programs in the United States. RESULTS: We interviewed all 41 PMR PDs. While 78% of PMR PDs reported interest in increasing ATOD education, for 68% it was not a high educational priority. Tobacco ranked in the top third of preventive medicine topics by 58%, while alcohol and other drugs ranked in the bottom third by 48% and 52%, respectively. Twenty-two percent of programs required a clinical ATOD rotation, most commonly smoking-cessation clinics. Only 29% of PMR PDs felt that residents were well prepared in clinical aspects of ATOD, while 60% felt that residents were prepared in ATOD research and public health issues. The most commonly reported barriers to ATOD training were lack of resident interest and defined competencies (64% each); limited faculty time (59%); limited teaching time (54%); lack of available teaching materials (53%); and lack of faculty expertise (51%). CONCLUSIONS: While the majority of PMR PDs recognize the importance of incorporating teaching about addictions into training, much of the ATOD education in PMRs focuses on tobacco alone. Setting educational standards, defining competencies, investing in faculty development, and creating ATOD curricular modules are important next steps toward preparing preventive medicine physicians to effectively reduce the public health toll of addictions.

Linking alcohol- and drug-dependent adults to primary medical care: a randomized controlled trial of a multi-disciplinary health intervention in a detoxification unit.

AIM: Pragmatic approaches to integration of medical care and substance abuse treatment are desired. We assessed the effectiveness of a novel multi-disciplinary clinic for linking patients in a residential detoxification program to primary medical care. PARTICIPANTS: We enrolled patients undergoing in-patient detoxification from alcohol, heroin or cocaine who had no primary care physician into a randomized controlled trial. The intervention consisted of a clinical evaluation at the detoxification unit in the health evaluation and linkage to primary care (HELP) clinic by a nurse, social worker and physician and facilitated referral to an off-site primary care clinic. The primary outcome of interest was attendance at a primary care appointment within 12 months. Secondary outcomes assessed over 24 months were addiction severity, health-related quality of life, utilization of medical and addiction services and HIV risk behaviors. FINDINGS: Of the 470 subjects enrolled, 235 were randomized to the HELP clinic intervention. Linkage to primary medical care occurred in 69% of the intervention group compared to 53% in the control group (P = 0.0003). The clinic was similarly effective for subjects with alcohol and illicit drug problems. Randomization to the HELP clinic resulted in no significant differences in secondary outcomes. CONCLUSIONS: The HELP clinic, a multi-disciplinary clinic located in a detoxification unit, effectively linked alcohol- and drug-dependent individuals to primary medical care. This intervention utilized a 'reachable moment', the period of addiction care, as a window of opportunity for linking substance abusers to medical care.

Alcohol consumption and HIV disease progression: are they related?

BACKGROUND: The relationship between alcohol consumption and HIV disease progression has received limited attention in the era of highly active antiretroviral therapy (HAART). METHODS: We assessed CD4 cell count, HIV RNA levels, and alcohol consumption in the past month, defined as none, moderate, and at risk, in 349 HIV-infected people with a history of alcohol problems. We investigated the relationship between alcohol consumption and HIV disease markers CD4 cell count and HIV RNA level, stratified by HAART use, using multivariable regression. RESULTS: No significant differences in CD4 cell count or HIV RNA level were found across the categories of alcohol consumption for patients who were not receiving HAART. However, among patients who were receiving HAART, log HIV RNA levels were significantly higher in those with moderate (2.17 copies/ml) and at-risk (2.73 copies/ml) alcohol use compared with none (1.73 copies/ml; p = 0.006). CD4 cell counts in those with moderate (368 cells/microl) and at-risk (360 cells/microl) alcohol use were lower than for subjects who reported none (426 cells/microl; p = 0.07). CONCLUSION: Among patients who have a history of alcohol problems and are receiving antiretroviral treatment, alcohol consumption was associated with higher HIV RNA levels and lower CD4 counts. No comparable association was found for similar patients who were not receiving HAART. Addressing alcohol use in HIV-infected patients, especially those who are receiving HAART, may have a substantial impact on HIV disease progression.

Discontinuation from HIV medical care: squandering treatment opportunities.

The purpose of this study was to assess HIV-infected patients' discontinuation of their primary care. One hundred ninety-eight consecutive outpatients were interviewed on initial HIV primary care presentation, assessed after six months about their discontinuation from primary care, and had characteristics associated with discontinuation determined. Primary care was not continued in 20 percent (40/198) of the cases. Cohort characteristics included 25 percent women; 44 percent black, 28 percent white, 25 percent Hispanic; 69 percent with highest yearly income < or = $16,000; 47 percent injection drug users; and median CD4 count 285/microL. Characteristics significantly associated (p < or = 0.05) with discontinuation were higher CD4 count, less education, no history of victimization, previous jail time, and site of medical care. One-fifth of HIV-infected patients did not remain engaged in primary care after establishing this essential link to treatment.

The relationship between sexual and physical abuse and substance abuse consequences.

This study examines the relationship between a history of physical and sexual abuse (PhySexAbuse) and drug and alcohol related consequences. We performed a cross-sectional analysis of data from 359 male and 111 female subjects recruited from an inpatient detoxification unit. The Inventory of Drug Use Consequences (InDUC), measured negative life consequences of substance use. Eighty-one percent of women and 69% of men report past PhySexAbuse, starting at a median age of 13 and 11, respectively. In bivariate and multivariable analyses, PhySexAbuse was significantly associated with more substance abuse consequences (p < 0.001). For men, age < or =17 years at first PhySexAbuse was significantly associated with more substance abuse consequences than an older age at first abuse, or no abuse (p = 0.048). For women, the association of PhySexAbuse with substance use consequences was similar across all ages (p = 0.59). Future research should develop interventions to lessen the substance abuse consequences of physical and sexual abuse.

Improving emergency medicine residents' approach to patients with alcohol problems: a controlled educational trial.

STUDY OBJECTIVE: We determine whether training using a structured skills-based intervention would improve emergency medicine residents' knowledge and practice in screening and intervening with patients presenting to the emergency department with alcohol problems. METHODS: In a controlled trial conducted at 2 similar emergency medicine residency programs associated with urban, Level I trauma centers, a 4-hour didactic, video, and skills-based workshop was conducted. Main outcome measures included (1) scores on changes in self-reported knowledge, current practice, self-efficacy, role-responsibility, attitudes and beliefs, and provider readiness to change from baseline to 1 year after intervention and (2) change in practice as measured by record review before and after intervention. RESULTS: The intervention group (n=17) had a significant increase in knowledge scores (P <.001) and practice with regard to percent of medical records with evidence of screening and intervention (17% before versus 58% after; 95% confidence interval [CI] 31 to 50; P <.001); no change was observed in the control group (n=19). These increases were significantly different between groups (95% CI 30 to 54; P <.001). There were no significant differences within or between groups for composite scores derived for current practice, self-efficacy, role responsibility, or readiness to change. CONCLUSION: A brief, structured, educational intervention for residents contributed to significant improvement in knowledge and practice with regard to patients with alcohol problems.

Injury among detoxification patients: alcohol users' greater risk.

BACKGROUND: Little information exists about serious injury in alcohol or drug abusers who seek detoxification. This study examined injury prevalence, and the impact of alcohol use on injury, among alcohol- and drug-dependent persons. METHOD: We enrolled patients at a detoxification unit into a prospective cohort study and performed follow-up interviews to determine the prevalence of injury. Baseline and follow-up (6, 12, 18, and 24 month) data were examined separately by using multivariate logistic regression to determine factors associated with self-reported episodes of serious injury. The main independent variable was self-reported first and second substances of choice at admission: alcohol only, drug only, or both. RESULTS: Overall, 24% of the 470 subjects reported at least one instance of serious injury over the 6-month period before detoxification. Similarly, approximately 20% of subjects had serious injury during each 6-month follow-up period. Injury in the past 6 months was highest among the 63% of subjects who reported alcohol as a drug of choice (28-29% vs. 16% for drug only), even after we controlled for potential confounders. Analysis of 2-year follow-up data revealed a similar association, after we controlled for baseline injury and alcohol consumption. CONCLUSIONS: Injury is a serious problem for a substantial proportion of patients who undergo detoxification, particularly those with alcohol dependence. This marked risk for serious injury persisted for 24 months after detoxification. Patients at detoxification, particularly those with alcohol problems, represent a high-risk population for injury that may benefit from interventions to reduce these preventable complications.

Professional satisfaction experienced when caring for substance-abusing patients: faculty and resident physician perspectives.

This survey aimed to describe and compare resident and faculty physician satisfaction, attitudes, and practices regarding patients with addictions. Of 144 primary care physicians, 40% used formal screening tools; 24% asked patients' family history. Physicians were less likely (P <.05) to experience at least a moderate amount of professional satisfaction caring for patients with alcohol (32% of residents, 49% of faculty) or drug (residents 30%, faculty 31%) problems than when managing hypertension (residents 76%, faculty 79%). Interpersonal experience with addictions was common (85% of faculty, 72% of residents) but not associated with attitudes, practices, or satisfaction. Positive attitudes toward addiction treatment (adjusted odds ratio [AOR], 4.60; 95% confidence interval [95% CI], 1.59 to 13.29), confidence in assessment and intervention (AOR, 2.49; 95% CI, 1.09 to 5.69), and perceived responsibility for addressing substance problems (AOR, 5.59; CI, 2.07 to 15.12) were associated with greater satisfaction. Professional satisfaction caring for patients with substance problems is lower than that for other illnesses. Addressing physician satisfaction may improve care for patients with addictions.

Burden of medical illness in drug- and alcohol-dependent persons without primary care.

Little is known about the frequency, severity, and risk factors for disease in drug- and alcohol-dependent persons without primary medical care. Our aims are to assess the burden of medical illness, identify patient and substance dependence characteristics associated with worse physical health, and compare measures of illness burden in this population. This was accomplished through a cross-sectional study among alcohol-, heroin- or cocaine-dependent persons without primary medical care who were admitted to an urban inpatient detoxification unit. The mean age of these patients was 35.7 (SD 7.8) years; 76% were male and 46% were Black. Forty-five percent reported being diagnosed with a chronic illness, and 80% had prior medical hospitalizations. The mean age-adjusted SF-36 Physical Component Summary (PCS) score was lower than the general U.S. population norm (44.1 vs 50.1; p<0.001). In multivariable analysis, female gender (adjusted mean change in PCS score: -3.71 points, p=.002), problem use of hallucinogens (-3.51, p=0.013), heroin (-2.94, p=0.008), other opiates (-3.20, p=.045), living alone (-3.15, p=.023), having medical insurance (-2.26, p=0.014) and older age (-.22 points per year, p=0.001) were associated with worse health. From these data, it seems that alcohol- and drug-dependent persons without primary medical care have a substantial burden of medical illness compared to age- and gender-matched U.S. population controls. While the optimal measure of medical illness burden in this population is unclear, a variety of health measures document this medical illness burden in addicted persons.
