Improving Access to Psychiatric Care for Patients in Primary Care (DSPP-PSY)

Improving Access to Psychiatric Care and the Fluidity of Care Pathways for Patients Suffering From Mental Disorders in Primary Care in France: Evaluation of a Psychiatric Consultation-liaison System

Getting a consultation with a psychiatrist within an appropriate time is one of the main issues reported by general practitioners (GP) for patients suffering from mental disorders in primary care. Consultation liaison in psychiatry is a system focused on general medicine-psychiatry collaboration. The aim of the present study is to evaluate the impact of the consultation-liaison on the adequacy of the access time to a psychiatric consultation according to the degree of urgency evaluated by the GP.

Faced with the saturation of the psychiatric care system, who recognizes the key role of the GP in mental health. Three-quarters of prescriptions for antidepressants and anxiolytics are performed by GPs, but less than one in four people with depression have been diagnosed and treated appropriately. The GPs describe difficulties in accessing psychiatric professionals and in particular to obtain a quick consultation with a psychiatrist. In different countries, psychiatric consultation-liaison (CL), centered on the collaboration of general medicine and psychiatry, have emerged. Two meta-analyzes and a Cochrane review were conducted on CL but no clinical trials were conducted in France. CL seems to improve patients' health at 3 months as well as their satisfaction and adherence to care. Results regarding the improvement of prescriptions from GP are encouraging. Better clinical trials are being requested and a need for medico-economic studies is also identified. In France, a psychiatry CL was born in Toulouse in 2017, the "DSPP". The present study plans a 2 groups randomized clinical trial, one group of GPs having access to DSPP, the other not. For a period of 3 months, the GPs propose to any patient, for whom they want a psychiatric consultation, to participate in the study and address him/her to a psychiatrist. The DSPP is an evaluation center without long-term patient follow-up. Only patient referred by his/her GP can get into the DSPP.

System focused on collaboration between general medicine (GP) and psychiatry, offering psychiatric assessment consultations and guidance for patient addressed by his/her GP. Referrals are made to the GP with support for care or the patient can be oriented to routine psychiatric care.

Patient will have usual care : Psychiatric care available in the Haute Garonne: psychiatric consultation by a liberal psychiatrist or by a psychiatrist working in public health center

The GPs of the intervention group will be able to refer their patients to the DSPP or to the routine care. The patient has a nursing telephone interview prior to one or few more psychiatric consultations. The time to obtain the psychiatric consultation is measured into the 2 groups. In both groups, questionnaires will be sent to the patient and their medico-administrative data will be collected passively over a period of 6 months after inclusion

psychiatric care available in the Haute Garonne: psychiatric consultation by a liberal psychiatrist or by a psychiatrist working in public health center.

Number of patients who had access to a consultation with a psychiatrist within 2 working days following the GP consultation for patients whose GP wishes an "urgent" consultation, within 7 working days for a "quick" consultation and within 21 working days for a "non-urgent" consultation.

Number of days between M0 (GP consultation) and M1 (psychiatric consultation) collected passively on the bases of Health Insurance, Information Systems Medicalization Program (PMSI) and DSPP

Number of passages to psychiatric emergencies within 6 months M0 passively collected on the basis of the PMSI (Information Systems Medicalization Program) of psychiatric emergencies

Number of suicide attempts and suicides within 6 months following M0 passively collected on the basis of the PMSI of the psychiatric emergencies and the Health Insurance

Mental health status measured at M0, 1 month and 6 months by questionnaires hand-delivered by the GP at M0 and sent at 1 and 6 months : - SCL-90-R scale: Scale exploring 9 symptomatic dimensions (somatization, obsession-compulsion, sensory traits, depression, anxiety, hostility, phobic anxiety, paranoid ideals, psychotic traits) by Likert scale in 5 points. Passing 15min.

Mental health status measured at M0, 1 month and 6 months by questionnaires hand-delivered by the GP at M0 and sent at 1 and 6 months : - the PHQ-9 scale for the diagnosis of major depressive episode and the intensity of depression. 9 questions are rated from 0 to 3 by the patient, ie a score of severity ranging from 0 to 27.

Duration of prescription of a benzodiazepine, antidepressant, hypnotic and antipsychotic treatment passively collected on the bases of Health Insurance

Composite criterion for the evaluation of compliance with antidepressant prescriptions including drug type (first-line serotonin reuptake inhibitors (IRS): 0 or 1) and duration (6 months minimum: 0 or 1) with a total score of 0 to 2

Number of prescription of a benzodiazepine, antidepressant, hypnotic and antipsychotic treatment passively collected on the bases of Health Insurance

Occupation, without profession (Number and duration of sick leave within 6 months following M0, passively collected on the bases of Health Insurance)

Patient satisfaction measured at 1 month of M0 by the Client Satisfaction Questionnaire (CSQ-8 scale)

Quality of life measured by the EuroQol (EQ-5D-5L) scale at M0 and 6 months by a clinical researcher by phone The EQ-5D-5L scale consists of 2 pages, a descriptive system EQ-5D and a visual analogue scale EQ . The descriptive system explores the following five dimensions: mobility, autonomy, usual activities, pain / discomfort and anxiety / depression. Each dimension is rated in 5 levels . The visual analogue scale is a vertical scale where the endpoints are labeled "best health imaginable" and "worst health imaginable"
