Dual diagnosis in an inpatient drug-abuse detoxification unit

In Spain, detoxification in general hospitals plays an important role in the medical care of patients. We aim to provide clinicians with information on the prevalence and correlates of psychiatric co-morbidity in drug abusers in detoxification. A sample of 115 substance-abuse inpatients (mean age 31.9 +/- 6.4 years) in a Detoxification Unit of a general university hospital was studied using the Spanish version of the PRISM. Most of the patients had multiple dependence diagnoses and co-morbid axis I or axis II psychiatric disorders. Patients with dual diagnosis showed lower psychosocial functioning than patients without co-morbidity and more dependence diagnoses due to cannabis and sedatives. A total of 80% of the patients successfully completed the detoxification process. The present results enhance the value of detoxification in a general hospital as a first step of the overall treatment strategy.

Cause and motivation in cases of non-fatal drug overdoses in opiate addicts

INTRODUCTION

Drug overdose (OD) is a frequent incident among opiate addicts. Survivors of ODs are at risk for additional and eventually fatal ODs. ODs may be classified as accidental (aOD) or deliberate (dOD). Investigations into the connection between OD and suicide attempts have led to insconsistent results.

PURPOSE

(1) to determine how many non-fatal ODs were dODs and how many were aODs; (2) to determine how many cases of dODs were motivated by explicit or by ambivalent suicidal intentions; (3) to determine how many cases of aODs had causes that might respond to preventative measures; (4) to compare the addiction histories of dODs and aODs; (5) to compare the drugs causing the ODs; and (6) to compare the severity of the ODs in both groups.

METHODS

Prospective study utilizing a standardized questionnaire to evaluate opiate-addicted patients admitted to our treatment unit for OD. All cases underwent standardized drug testing to identify drug use patterns.

RESULTS

Seventy-four cases of OD underwent standardized interviews after awakening. Forty-three percent of the cases were dOD. Cases of dOD had significantly more OA in substitution programs, more previous ODs, and more often consumed methadone and cocaine. Among dODs, 22.5% had suicidal intention and 9.6% were ambivalent about committing suicide; background motivations were most often conflicts with spouses. Fifty-seven percent of the cases were aOD. Cases of aODs had significantly more potential lethal intoxications and had heroin detected more frequently. aODs happened with unexpected pure heroin (46%), in combination with alcohol (36%), as relapse after abstinence (40%) or after institutionalized treatment (19%). This group should be accessible for targeted education.

Estimating prevalence of problem drug use at national level in countries of the European Union and Norway

OBJECTIVES

This paper will present the most recent estimates for problematic drug use in European Member States and explore the problems of comparability.

METHODS

Estimates of problematic drug use, derived according to agreed guidelines, were collected from all EU countries and Norway. Methods included multipliers based on treatment, police, mortality or AIDS/HIV data, the capture-recapture method and the multivariate indicator method. Prevalence estimates were transformed into rates per 1000 population aged 15-64 years.

RESULTS

Target populations varied according to data selection. Estimates for six partially overlapping types of drug use could be identified: 'problem opiate use', 'problem opiate or cocaine use', 'problem amphetamine or opiate use', 'problem drug use', '(current) injecting' and 'life-time injecting'. Rates of injectors ranged from 2.6 in Germany to 4.8 in Luxembourg; rates in Austria, Denmark, Finland, Portugal and the United Kingdom fell within this range. For problem opiate use, a group of high prevalence countries were found with average rates exceeding six cases (Italy, Luxembourg, Spain and the United Kingdom) and a group with lower prevalence with average rates close to three cases (Austria, Germany, Ireland, the Netherlands). Rates obtained for France (problem opiate or cocaine use), Finland and Sweden (problem amphetamine or opiate use) are not directly comparable and fall between these rates.

CONCLUSIONS

Cross-national comparisons should be made with care and estimated target populations may vary greatly between countries. For estimating various forms of problem drug use at national level, a multi-method approach is recommended.
