Prevalence of childhood physical and sexual abuse in veterans with psychiatric diagnoses.

We examined the prevalence of childhood (≤ 18 years) physical and sexual abuse reported among patients admitted to the psychiatric inpatient service and the differential rates of this abuse associated with psychiatric diagnoses. This study consisted of a retrospective chart review of 603 patients admitted to a psychiatric ward during a period of 1 year at Atlanta Veterans Affairs Medical Center who had data on childhood physical and sexual abuse. The prevalence of reported childhood physical or sexual abuse in this inpatient clinical population was 19.4% (117/603). The prevalence of reported physical abuse was 22.6% (19/84) in the women and 12.0% (62/519) in the men (p = 0.008); the prevalence of sexual abuse was 33.3% (28/84) in the women and 7.7% (40/519) in the men (p < 0.0001). More patients with depressive disorders reported sexual abuse than did those without these disorders. More patients with posttraumatic stress disorder (PTSD) reported physical and sexual abuse than did those without these disorders. Stratifying by race, sex, and diagnoses, multivariate analyses showed that the women with PTSD had a greater likelihood to report physical abuse (p = 0.03) and sexual abuse histories (p = 0.008) than did the women without PTSD. The men with substance-induced mood disorder (p = 0.01) were more likely to report physical abuse compared with the men without substance-induced mood disorder. Screening for abuse in patients with depressive disorders and PTSD is warranted to tailor individualized treatments for these patients. More research is needed to better understand the potential implications of childhood abuse on psychiatric diagnoses.

Heroin anticraving medications: a systematic review.

BACKGROUND: Heroin craving is a trigger for relapse and dropping out of treatment. Methadone has been the standard medication for the management of heroin craving. OBJECTIVES: We explored the medication options other than methadone which may have heroin anticraving properties. METHODS: To be selected for the review, articles had to include outcome measures of the effect of the studied medication on subjective and/or objective opiate craving and be of the following two types: (1) randomized, controlled, and/or double-blind clinical trials (RCTs) examining the relationship between the studied medication and heroin craving; (2) nonrandomized and observational studies (NRSs) examining the relationship between the studied medication and heroin craving. Thirty-three articles were initially included in the review. Twenty-one were excluded because they did not meet the inclusion criteria. We present the results of 12 articles that met all the inclusion criteria. RESULTS: Some new medications have been under investigation and seem promising for the treatment of opiate craving. Buprenorphine is the second most studied medication after methadone for its effect on opiate craving. At doses above 8 mg daily, it seems very promising and practical for managing opiate craving in patients receiving long-term opioid maintenance treatment. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: In doses higher than 8 mg daily, buprenorphine is an appropriate treatment for opiate craving. More research with rigorous methodology is needed to study the effect of buprenorphine on heroin craving. Also more studies are needed to directly compare buprenorphine and methadone with regard to their effects on heroin craving.

Methadone maintenance dosing guideline for opioid dependence, a literature review.

To date, methadone dosing is still an issue of debate and controversy among clinicians who are involved in methadone maintenance programs. The authors conducted a literature review to update clinicians about this issue and provide recommendations for proper methadone dosing. Studies eligible for inclusion in the review were retrieved from the PubMed database by searching for reports published between 1990 and September 2008 using the major medical subject headings Methadone (all fields) and dose. Only articles written in English were included. Additional reports were identified from the reference lists of retrieved articles and by manual review of the tables of contents of journals on drug of abuse included in the psychiatry and substance abuse subject category listing 2008 of the Journal Citation Reports. Abstracts of medical meetings were excluded. Twenty-four articles were included in the review. Twelve are randomized, controlled, or double-blind clinical trials, 10 are non-randomized and observational studies, and 2 are meta-analyses. Currently, the consensus is to have a goal for methadone dosing in the range of 60 to 100 mg daily. For patients who continue to use illicit opiates while prescribed this dose range, clinicians may consider doses greater than 100 mg daily. However, this is not the current consensus but rather is based on the limited promising data the authors have; it could be considered if the benefits outweigh the risks for some patients.

Onsite QTc interval screening for patients in methadone maintenance treatment.

To improve the electrocardiogram screening process and early detection of patients at high risk for cardiac arrhythmias, the authors created a model in their clinic where they provided an onsite electrocardiogram screening that might be feasible and practical. The authors then performed a retrospective chart review to access the efficacy and feasibility of their new onsite procedure in identifying methadone maintained patients at high risk for cardiac arrhythmias. Records from all patients who are currently or had previously been maintained on methadone in the methadone maintenance program at the Atlanta VA Medical Center between 2002 and 2009 were evaluated. Of the 140 patients treated at the clinic between 2002 and 2009, 85 were excluded from the study because they had been treated as guests (had been in treatment in other clinics but received methadone dosing temporarily from our clinic), were treated in the clinic for less than 6 months, or dropped out of treatment. Thus, 55 patient charts were selected for review. Most patients (95%) received baseline and annual electrocardiogram screening. The average baseline QTc was (417 +/- 30) and most recent QTc (442 +/- 25). This QTc prolongation from baseline showed statistical significance (P < .0001). Sixty-seven percent of patients had statistically significant QTc prolongation from baseline but was less than 450 ms (mean: 428 +/- 16, P = .008). Twenty-seven percent of patients had statistically significant QTc prolongation from baseline of more 450 ms but was less than 500 ms (mean: 460 +/- 8, P < .0001). Six percent of patients had statistically significant QTc prolongation from baseline of more 500 ms (mean: 503 +/- 1.15, P = .027). Recent cocaine use was the only individual variable that showed statistically significant correlation with QTc prolongation (F = 6.98, P = .01). The authors demonstrated in this study that providing an onsite electrocardiogram screening with a focus on patient education and limiting the referral to specialty care for patients at high risk for cardiac arrhythmias could be practical and feasible.

Benefits of retention in methadone maintenance and chronic medical conditions as risk factors for premature death among older heroin addicts.

BACKGROUND: Methadone maintenance treatment reduces rates of premature mortality in heroin addicts. However, few published studies have addressed the effectiveness of treatment, mortality rates, or causes of death in older (geriatric) patients maintained on methadone. Identifying risk factors for premature mortality and potential targets for early intervention may reduce rates of premature mortality in older patients maintained on methadone. METHODS: We conducted a retrospective chart review for patients enrolled in the methadone maintenance program at the Atlanta Veterans Affairs Medical Center. We reviewed the charts of 91 patients and collected the following information: demographics (age, gender, marital status, and race); composite score at admission on the Addiction Severity Index (ASI); most recent ASI score for alcohol use, drug use, and medical, psychiatric, family, legal, and employment problems; results of urine drug screens for opiates, cocaine, and benzodiazepines (first 4 screens after admission and last 4 screens); dose and duration of methadone treatment; HIV and hepatitis B and C status; tobacco smoking; presence of diabetes mellitus, hypertension, heart disease, chronic obstructive pulmonary disease, or cancer; history of intravenous drug use; and missed primary care appointments (last five appointments). RESULTS: A statistically significant association was found between diabetes mellitus and between liver and gastrointestinal cancer and premature mortality in this sample of older patients maintained on methadone (OR=30.79, p=0.008 for diabetes mellitus; OR=19.91, p=0.017 for cancer). Patients who remained in treatment showed statistically significant improvement in ASI scores for problems related to drug use and for psychiatric, medical, and legal problems. They showed a nonsignificant trend toward reduction of problems associated with alcohol use. The group of patients who dropped out of methadone treatment did not show statistically significant improvement on any area of the ASI except family problems. The group who remained in treatment also showed a statistically significant reduction in drug use when results of the first four and last four urine drug screens for opiates, cocaine, and benzodiazepines were compared (p<0.0001 for opiates and cocaine, p=0.02 for benzodiazepines).On the other hand, the group who dropped out of methadone treatment did not show any statistically significant reduction in drug use based on urine screens (p=0.05 for opiates, p=0.38 for cocaine, and p=0.53 for benzodiazepines). CONCLUSIONS: The results presented here suggest potential targets for intervention related to lifestyle risk factors and comorbid medical conditions, such as nicotine dependence and diabetes mellitus, that may have the potential to improve health outcomes for older patients with opioid dependence.

High dose versus moderate dose methadone maintenance: is there a better outcome?

Methadone dosing has been an issue of controversy among clinicians for a long time. Few recent studies reported that doses above 100 mg daily seem promising in better control of illicit opiate use for some patients, but more research is needed to support that notion. A retrospective chart review for patients maintained on methadone at Atlanta Veterans Affairs Medical Center was conducted. Patients were categorized into two groups: patients on a methadone dose of 60 to 100 mg daily (n = 34) and patients on a methadone dose greater than 100 mg daily (n = 25). Those charts were compared for urine drug screens for opiates and cocaine (first four from admission and most recent four screens), retention or drop out from the program, and Addiction Severity Index (ASI) composite score at admission and most recent score. The results of the first and last four urine drug screens for opiates showed that the moderate dose group was positive 23% and 17%, respectively. However, the high dose group was positive 14% and 8%, respectively. These results showed statistical significance (Chi-Square = 8.04, df = 3 and p =.03). ASI scores for drugs did not show statistically significant improvement for the moderate dose group (p =.19) but showed statistically significant improvement for the high dose group (p =.0002) when the result of the first and last ASI scores among each group were compared. The ASI scores for family problems showed statistically significant improvement for the moderate dose group (p =.03). High doses of methadone greater than 100 mg daily may provide a better outcome for illicit opiate use among some patients who would not respond to moderate doses.
