Studio Morfeo 2: survey on the management of insomnia by Italian general practitioners.
BACKGROUND AND PURPOSE: To carry out an observational epidemiological survey (Studio Morfeo 2) in order to define the management procedures of insomnia in a large Italian population presenting directly to the general practitioner (GP). PATIENTS AND METHODS: Each GP recruited five insomniac subjects in the course of 1 week or 5 consecutive office days over a period of 2 weeks. On each office day, a brief questionnaire (Q1) including five questions investigating insomnia symptoms and current use of treatment was administered to the first 10 patients who referred to the GP office for reasons associated with their own health. The first patient of each day classified as insomniac underwent a second investigation based on a more detailed questionnaire (Q2) including demographic variables, socio-economic status, general medical conditions, severity, duration and clinical features of insomnia, daytime dysfunction, sleep satisfaction and therapeutic management. RESULTS: In a primary care setting, insomnia symptoms are often persistent (>1 year), recurrent (>1/week) and accompanied by daytime consequences. Two out of three patients with insomnia symptoms are dissatisfied with their sleep. In most cases, insomnia symptoms are underrated both by the patients, who cover the problem or reject treatment, and by the GP, who limits intervention on the sleep disorder (scarcely modifying ongoing therapy both in responders and in non-responders). In responders, treatment was confirmed in 91% of cases and discontinued in only 2%. When there was no improvement, or if insomnia symptoms became worse (non-responders), treatment was nevertheless continued in 74.5% of cases, either maintaining the same ineffective dose, increasing the dose, or adding another drug or a non-pharmacological procedure. Regardless of specific medication, the Italian GP privileges the pharmacological approach, which is fourfold more frequent than non-pharmacological therapy (78.6 versus 18.2%). Non-benzodiazepine hypnotic drugs are mostly prescribed when the GP decides to apply medication in previously untreated patients with insomnia symptoms. Self-administration is not unusual among the patients with insomnia symptoms and is more common among non-responders. CONCLUSIONS: Italian GPs tend to confirm the ongoing therapy and avoid re-evaluation of the treatment regimen. Limited use of non-pharmacological treatment in the Italian primary care setting is in line with this conservative approach of the GPs who tend to be problem-solvers rather than problem-seekers.
