Objective: In order to develop demand-driven health information about z-drugs and benzodiazepines, we aimed to identify information needs of people at risk of dependency., Methods: We conducted three focus groups with different target groups: Younger people with sleep disorders (N=7), middle-aged women with occasional/regular intake of z-drugs or benzodiazepines (N=6) and older people with regular drug intake., Results: The information needs primarily refer to the areas "sleep disorders" (esp. alternative treatment options), "z-drugs and benzodiazepines" (esp. risks of intake) and "offers of assistance" (esp. contact points)., Conclusion: The thematic overlaps indicate that all affected groups can profit from general information about sleep disorders, different treatment options and risks. Additionally, information services should also focus on guidance and referral in the help system., Competing Interests: Uwe Verthein erhielt innerhalb der letzten 3 Jahre Vortrags-, Beratungshonorar und Reisekostenerstattungen von Mundipharma GmbH sowie finanzielle Projektförderung und Reisekostenerstattungen von CAMURUS GmbH.

Background: Long-term use of benzodiazepines (BZD) and Z-drugs is associated with the risk of developing dependency. Many older patients use these drugs for long durations, which is often associated with low-dose dependency without an increase in dose., Aim: The aim of this study is to investigate the reasons, symptoms, and side effects, as well as the prescription conditions among older patients who were prescribed BZD or Z-drugs within the last 12 months., Methods: A 9-page questionnaire was sent to 4,000 patients of the AOK-NordWest, stratified according to age group (50-56 years;>65 years) and intake behavior (long-term use/ guideline incompatible; short-term use/ guideline compatible). Patients provided demographic data and indicated on a comprehensive list of BZD and Z-drugs, which substances they had used or were currently using. In addition, patients were asked about the reasons and underlying symptoms for taking these medications, possible side effects, and previous attempts to discontinue the medications., Results: A total of 466 patients returned completed questionnaires (11.7%). A further 43 privately insured patients were recruited through pharmacies. 169 patients, mainly from the group with guideline-compatible prescriptions, indicated that they had never taken these medications. The remaining 340 patients were 68.5% female and the average age was 72.1 years. Compared to patients with guideline-compatible prescriptions, a greater proportion of patients with guideline-incompatible prescriptions were taking Z-drugs. The average daily dose (DDD) consumed was significantly higher than in those with guideline-compatible prescriptions, although on average both patient groups took low doses (<1 DDD) of the medication. In both groups, the main reason for taking BZD and Z-drugs was sleeping problems., Conclusions: Considering the recommendation that BZD and Z-drugs are to be taken only short-term for sleeping problems, the extent of insomnia indications is high. The low doses suggest a careful and controlled prescription behavior in both groups, with the majority of long-term consumers likely to have developed low-dose dependency. This is associated with only a limited need for intervention, since only few medication-dependent people underwent addiction treatment., Competing Interests: Uwe Verthein erhielt innerhalb der letzten 3 Jahre Vortrags- und Beratungshonorar sowie Reisekostenerstattungen von Mundipharma GmbH.

Objective: The majority of medication-dependent persons uses sedatives and hypnotics for many years. In this study we describe trends of benzodiazepine and z-drug prescriptions over a 10-years period., Methods: Prescriptions from 2006 to 2015 (based on German statutory health insurances) from the North German Pharmacy Computing Centre (NARZ) were analysed for the Federal states Schleswig-Holstein, Hamburg, Lower Saxony and Bremen. Data were classified as appropriate (in accordance with the guideline) or inappropriate/risky prescription patterns., Results: In a 10-years period 1.64 Million patients received benzodiazepine and/or z-drug prescriptions. Two thirds were women (65.3 %). More than half were 60 years or older. The percentage of patients with appropriate prescriptions (less than 2 months) increased from 51.7 % in 2006 to 60.2 % in 2015. The rate of inappropriate or risky prescription patterns which can be indicative of misuse or dependence dropped from 34.8 % in 2006 to 27.1 % in 2015., Conclusion: Over the past years the amount of inappropriate or risky benzodiazepine and z-drug prescriptions (which are not in accordance with the guideline) among patients with statutory health insurance is steadily decreasing. However, two fifths of the patients still received prescriptions for long-term intake or in higher doses. It remains unclear to what extent private prescriptions are used for inappropriate or long-term prescriptions of benzodiazepines and z-drugs., Competing Interests: Uwe Verthein erhielt innerhalb der letzten 3 Jahre Vortrags- und Beratungshonorar von Mundipharma GmbH sowie Reisekostenerstattungen von Mundipharma GmbH und CAMURUS GmbH.

Background: An estimated 1.4 to 2.6 million people in German suffer from drug dependence. Most of them are long-term users of benzodiazepines (BZD), Z drugs (ZD), or opioid analgesics (OA)., Methods: This analysis is based on prescription data from patients of the national statutory health insurance system in the German federal states of Schleswig-Holstein, Hamburg, Bremen, and Lower Saxony. Drug-taking trends, duration, dosage, and long-term use of BZD, ZD, and OA in the years 2006 to 2015 are analyzed; prevalences are estimated for the years 2006 to 2016., Results: In 2006, 7.7% of patients received at least one prescription for a BZD, ZD, or OA; in 2016, 7.0% did. Over the period of analysis, a marked drop was seen in prescriptions of BZD and a slight fall in prescriptions of ZD (2006: BZD 3.5%, ZS 1.1%; 2016: BZD 2.0%, ZS 0.8%), but there was also an increase in prescriptions of OA, from 4.2% to 4.9%. The number of defined daily doses (DDD) prescribed per year fell for both BZD and ZD. For OA, the number of DDD prescribed per year rose from 2006 to 2009 and decreased by a small amount in subsequent years. The proportions of BZD and ZD patients who had long-term prescriptions fell over time, while the corresponding percentage of OA patients rose., Conclusion: Nearly one-fifth of all prescriptions for BZD were long-term prescriptions for an entire year, in violation of the relevant guidelines. The rising prevalence of OA use was in the expected range in view of the aging population, but the number of prescriptions rose among younger patients as well. This trend toward more common treatment with opioid analgesics should be critically examined.

Background: In Germany, about 1.4 to 2.6 million people are dependent on prescription drugs, mainly benzodiazepine derivatives and opioid analgesics. Despite this large number of affected people, studies on prescription behaviour and drug intake are scarce. There are particularly few empirical findings available with regard to elderly people age 65 and over who are disproportionally affected by prescription drug abuse., Methods: The North German Pharmacy Computing Centre (Norddeutsches Apothekenrechenzentrum, NARZ) collects the prescription data of about 11 million citizens and covers over 80% of drug pharmacies in North Germany. Based on the data from NARZ, we evaluate person-related prescriptions of benzodiazepines, Z‑drugs and opioid analgesics. By means of incremental calculations, we determine the prevalence of prescription drug use, the long-term intake, the average daily dose of these medications and present this information as a five-year trend (2006-2010)., Results: In 2006, 10.6% of the members of public healthcare system were prescribed at least one of the medications under study. This proportion hardly changed within the five-year span. The share of patients with benzodiazepine prescription steadily decreased from 2006 (5.5%) to 2010 (5.1%), especially among elderly people. While the prevalence of Z‑drug prescriptions remained the same at about 1%, there was a slight increase in prescriptions of opioid analgesics with 5.4% in 2006 to 5.7% in 2010. The proportion of patients with long-term prescriptions decreased with regard to benzodiazepines (from 17.0 to 12.8%) and Z‑drugs (from 24.3 to 21.2%), but increased for opioid analgesics (from 19.2 to 21.2%)., Conclusion: The analytical method used in this study is an innovative epidemiological approach to evaluate person-related register data over the course of several years. Establishing a monitoring system of prescription drugs with potential for dependence may allow for a quicker identification of trends and initiation of appropriate measures.

Background: Data of the Central Bureau of Statistic of Nepal from 2008 show a total of more than 46,000 illegal drug users, out of which 61% are injecting drug users (IDU). An injecting mix of medicines like opioids, benzodiazepines and antihistamines (the so-called South Asian cocktail) was prevalent. Furthermore, it is estimated that about 70,000 people are living with human immunodeficiency virus (HIV). The government of Nepal has started realizing and recognizing drug use and HIV as significant health and social issues. Harm reduction programs such as needle syringe exchange and opioid substitution treatment are being implemented., Methods: The aim of this study is to obtain specific knowledge on the drug use behaviour and the health status of drug users with a focus on HIV in drug users with concurrent injection of opioids, benzodiazepines and antihistamines. After an initial mapping of Kathmandu Valley, 300 drug users in contact with different treatment and counselling centres were randomly chosen for the interviews. The research questionnaire was designed according to the European Addiction Severity Index (EuropASI) and Maudsley Addiction Profile standards., Results: Ninety-one percent of the respondents are male and 9% female. Mean age is 28.7 years. Ninety-five percent are injecting drug users with a mean of 8.7 years of drug use history. Eighty-six percent are injecting different 'cocktails', usually made of buprenorphine, diazepam, promethazine and/or other substances (30-day prevalence). Similarly, 48% use heroin, whereas only 2% take cocaine/crack. Among those tested for HIV (N = 223), 33% are positive (25% of the sample population). Compared to the other drug users (mainly heroin), the cocktail users show a higher HIV infection rate and more co-infections. Furthermore, risk behaviour, as e.g. needle sharing, is much more common among the cocktail users., Conclusion: Currently, the mixture of medicines, opioids, benzodiazepines and antihistamines, is the predominant drug in Nepal; the pharmaceutical drugs needed to prepare the cocktail are less expensive than heroin and relatively easy to acquire. The cocktail users show a higher risk behaviour regarding the transmission of HIV than heroin drug users. It needs to be considered which HIV prevention measures are necessary to target the specific needs of drug users who inject a mixture of opioids, benzodiazepines and antihistamines, since the available services (such as needle syringe exchange) do not seem to cover their specific needs (high percentage of needle sharing).

Background: The number of persons with a dependence on prescription drugs such as sedatives or tranquilizers in Germany is estimated at between 1.4 and 1.9 million. According to national addiction treatment documentations only very few of them seek help in specialised treatment services. The majority of prescription drug-dependent people use benzodiazepines. This medication is usually prescribed by physicians and according to German guidelines it should be prescribed only for limited, short periods and in low doses., Objective: This study aims to determine the extent of the problematic prescription of benzodiazepines and non-benzodiazepines., Methods: We used prescription data from the Northern Germany Computing Centre for Pharmacies registered between 2005 and 2007. For the German regions of Hamburg, Bremen and Schleswig-Holstein, benzodiazepine prescriptions during an individual prospective period of 12 months were analysed., Results: From July 2005 to June 2006, 294 143 prescriptions of benzodiazepines and non-benzodiazepines were recorded for 78 456 citizens of Hamburg and billed at the expenses of the governmental health insurance funds. In the course of one observed patient year, 51.1% of benzodiazepine prescriptions were in accordance with the German guidelines. 15.6% of the patients were supplied on a long-term basis (0.5-1 DDD during at least 2 months). Prescriptions for women and persons older than 70 years were disproportionately high. Compared with the Federal states of Bremen and Schleswig-Holstein, Hamburg does not show an exceptional position., Conclusion: The prescription of benzodiazepines which is not in accordance with the relevant national guidelines is widespread and calls for discussion and education among physicians and pharmacists. Furthermore, professional addiction services should reconsider ways to help and attract prescription drug-dependent people to cover their needs, as their numbers will grow in an aging society., (© Georg Thieme Verlag KG Stuttgart · New York.)

Benzodiazepine (BZD) use has been found to be associated with poorer psychosocial adjustment, higher levels of polydrug use and more risk-taking behaviors among opioid dependent patients. The aim of this paper is to analyze the correlation between BZD use, BZD prescription and treatment outcome among participants in the German trial on heroin-assisted treatment. 1015 patients who participated in the study comparing heroin-assisted and methadone maintenance treatment (HAT & MMT) for 12 months were included in the analysis. Analyses were carried out to assess the association of treatment outcome with baseline BZD use, with ongoing BZD use and with different patterns of BZD prescription. Baseline BZD use correlated with lower retention rates but not with poorer outcome. Ongoing BZD use correlated with poorer outcomes. Significantly better outcomes were found in the course of phobic anxiety symptomatology for those with regular prescription of BZD. The percentage of BZD positive urine tests decreased more in HAT than in MMT. Poorer outcome for benzodiazepine users may be mediated by a higher severity of addiction. Cautious prescribing of benzodiazepines may be beneficial due to the reduction of overall illicit use., (Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.)
