| Scientific title | A cluster randomised controlled trial on the efficacy of a structured educational intervention or minimal intervention versus usual care for discontinuing long term benzodiazepine use in primary care |
| Study acronym | BENZORED |
| Study hypothesis | Although short-term efficacy of benzodiazepines (BZD) is well established, long-term efficacy remains controversial and long term use is usually not recomended because of potential adverse effects and the risks of tolerance and dependence, increased risk of hip fractures, motor vehicle accidents and memory impairments. Most guidelines recommend restricting their use to short periods only, but nevertheless they are widely prescribed. Objective: To evaluate the efficacy of a structured educative intervention (SEI) and of a minimal intervention (MI) performed by the family General Practitioner (GP) to discontinue long term BZD use, compared to usual care. To evaluate the safety of these interventions in anxiety and depression symptoms, sleep quality and alcohol consumption. Hypotheses: 1. In primary care patients on long-term benzodizapine, a structured educational intervention results in a cessation rate of 40% after one year, compared to 25% with minimal intervention and less than 10% with usual care 2. The interventions proposed (EI and MI) do not induce more symptoms of anxiety and depression or affect quality of sleep and alcohol consumption compared to the control group |
| Ethics approval(s) | The Ethics Committee of the Balearic Islands (Comité Ético Investigación Clínica [CEIC])approved on the 29th April 2009 |
| Condition | Benzodiazepine use, reduction and withdrawal |
| Intervention | Patients were randomised to one of three groups, comparing two strategies for the reduction of chronic bendzodizepine and a control group: 1. Structured educational intervention: 1 educational interview (20 - 25 minutes) which addresses some specific aspects of chronic use of benzodiazepines with a pattern of gradual dose reduction of benzodiazepine and 4 - 6 subsequent follow-up visits to control the gradually descending dose 2. Minimal intervention: 1 educational interview (20 - 25 minutes) which addresses some specific aspects of chronic use of benzodiazepines with written information on the pattern of gradually reducing the dosage of benzodiazepine 3. Control group: usual clinical practice, no intervention visits There will be follow up visits at 6 and 12 months, of 35 minutes duration. |
| Intervention type | Other |
| Primary outcome measure | Benzodiazepine use at 12 months |
| Secondary outcome measures | 1. Anxiety and Depression Scale 2. Quality of Sleep Scale 3. Alcohol consumption Outcomes will be measured at baseline, 6 and 12 months. |
