BACKGROUND: Sedative-hypnotics (SHs) are widely used in France but there are no available data addressing their prescription specifically in hospitalized older patients. The objective is thus to determine the cumulative incidence of sedative-hypnotic (SH) medications initialized during a hospital stay of older patients, the proportion of SH renewal at discharge among these patients and to study associated risk factors. METHODS: We conducted a retrospective observational study in six internal medicine units and six acute geriatric units in eight hospitals (France). We included 1194 inpatients aged 65 and older without SH medications prior to hospitalization. Data were obtained from patients' electronic pharmaceutical records. Primary outcome was the cumulative incidence of SH initiation in the study units. Secondary outcomes were the proportion of SH renewal at discharge and risk factors for SH initiation and renewal at discharge (patient characteristics, hospital organization). A Cox regression model was used to study risk factors for SH initiation. A mixed effects logistic regression was used to study risk factors for SH renewal at discharge. RESULTS: SH initiation occurred in 21.5% of participants 20 days after admission. SH renewal at discharge occurred in 38.7% of patients who had initiated it during their stay and were discharged home and in 56.0% of patients discharged to rehabilitation facilities. Neither patients' characteristics nor hospital organization patterns was associated with SH initiation. SH initiation after the first six days after admission was associated with a lower risk of SH renewal in patients discharged to rehabilitation facilities (OR = 0.19, 95% CI: [0.04-0.80]). CONCLUSIONS: Hospitalization is a period at risk for SH initiation. The implementation of interventions promoting good use of SHs is thus of first importance in hospitals. Specific attention should be paid to patients discharged to rehabilitation facilities.

BACKGROUND: The burden of Sedative-Hypnotics (SHs) has been known since the 1980s. Yet, their consumption remains high. A systematic review of the literature should help to assess efficient interventions to improve the appropriate use of SHs in sleep disorders. OBJECTIVES: To identify and assess regulatory and educational interventions designed to improve the appropriate use of SHs for insomnia treatment. METHODS: We conducted a systematic review of the literature according to PRISMA guidelines. A systematic search covering the period 1980-2015 was carried out in Medline, Web of Science, Embase and PsycInfo. We included studies reporting the implementation of regulatory or educational strategies directed towards patients and/or healthcare professionals to improve the appropriate use of SHs to treat insomnia in the community, hospitals and nursing homes. RESULTS: Thirty-one studies were included: 23 assessed educational interventions (recommendations by mail/email, computer alerts, meetings, mass media campaigns, prescription profile), 8 assessed regulatory interventions (prescription rule restriction, end of reimbursement). The most recent was implemented in 2009. Restrictive prescription rules were effective to reduce the consumption of targeted SHs but led to a switch to other non-recommended SHs. Among educational interventions, only 3 studies out of 7 reported positive results of mono-faceted interventions; whereas, 13 out of the 16 multi-faceted interventions were reported as efficient: particularly, the active involvement of healthcare professionals and patients and the spread of information through mass media were successful. The risk of bias was high for 24 studies (mainly due to the design), moderate for 3 studies and weak for 4 studies. CONCLUSION: Educational multifaceted studies are presented as the most efficient. But further better designed studies are needed to make evidence-based results more generalizable.

OBJECTIVES: To determine whether potentially inappropriate medications (PIMs) or potentially inappropriate associations (PIAs) prescribed knowingly are associated with patient monitoring. DESIGN: Prospective observational study. SETTING: Geriatric units (n = 56) in 28 hospitals. PARTICIPANTS: Inpatients aged 75 and older (N = 1,327). MEASUREMENTS: Potentially inappropriate prescriptions (PIP) were defined as a PIM or a PIA selected by an expert board from lists of explicit criteria (Beers, Priscus, Laroche, French Health Agency) using a Delphi process. They were considered to be prescribed knowingly if they were maintained after reassessment by the geriatrician and the clinical pharmacist. Primary outcome was the rate of PIPs maintained (prescribed knowingly) and for which a geriatrician declared that specific monitoring was performed. Secondary outcomes were the parameters monitored and the rate of participants receiving knowingly a PIP. RESULTS: One thousand sixty-three PIPs were detected in 607 participants (46%). After reassessment, 826 (78%) PIPs were maintained in 490 participants (37%), the main reasons being participant's regular treatment and lack of alternative. Psychotropic (36%), cardiovascular (including antithrombotics) (29%), and laxative or antiemetic drugs (16%) were the most-frequent classes prescribed knowingly. The geriatricians declared to perform clinical or biological monitoring for 69% (n = 570) of PIMs or PIAs prescribed knowingly. Three types of specific monitoring were identified: clinical, biological, and follow-up with a specialist. CONCLUSION: Approximately three-quarters of PIMs or PIAs were prescribed knowingly, of which 69% were monitored, with wide variations in occurrence and in quality according to drug classes. This underlines the need for accurate guidelines on PIP monitoring.

BACKGROUND: Automated dispensing cabinets (ADCs) have been tested and approved for medication management in hospitals. OBJECTIVES: First, to evaluate the logistics and organisational effect of a similar system for management of sterile medical devices in a medical intensive care unit (ICU). Second, to assess the cost savings of this new organisation for the sterile medical devices budget of this department. METHODS: The organisational effect was evaluated by comparing (1) the workload of head nurse, nursing auxiliary and pharmacy technician and (2) sterile medical devices emergency orders, 1â year before and after implementation of three ADCs and 100 wireless open-access devices. The hospital's costs (ADC, wireless devices and software) and benefits (stock value and resupplying value before and after implementation) were evaluated. RESULTS: Employment of ADCs led to organisational improvement: the total time saved by the pharmacy and ICU together was 34% of the time spent before introduction. The number of emergency orders decreased from 6% to 1% of total orders after 1â year. 55â 000 were saved (stock value + resupplying value) 1â year after introduction of ADCs. These benefits were almost equal to the cost of introducing the system. CONCLUSIONS: ADCs could provide an innovative and efficient solution for the management of sterile medical devices in hospitals. Further investigations are needed to complete the financial evaluation, and to develop this system to provide a secure a medical devices circuit.
RESUMEN
Administration of cyamemazine, an antipsychotic drug with anxiolytic properties, together with other antipsychotic agents is common in patients with schizophrenia. This retrospective study investigated the effects of cyamemazine on the steady-state plasma concentrations of risperidone and 9-hydroxyrisperidone in 47 patients treated with 1 to 12 mg/day of risperidone. Of these 47 patients, 24 were receiving cyamemazine comedication ("cyamemazine" group) and 23 patients were treated with risperidone alone ("control" group). Plasma concentrations were measured using a high-performance liquid chromatographic method with photodiode-array ultraviolet detection. The median plasma concentration of risperidone was significantly higher in the cyamemazine group (31.5 ng/mL) than in the control group (5.0 ng/mL), whereas the 9-hydroxyrisperidone median concentration was significantly lower in the cyamemazine group (16.5 ng/mL versus 39.0 ng/mL in the control group). However, the sum of risperidone plus 9-hydroxyrisperidone (active moiety) plasma concentration was not significantly affected by cyamemazine comedication. A combination with cyamemazine resulted in an inverted metabolic ratio (risperidone/9-hydroxyrisperidone). These findings suggest that cyamemazine inhibits the 9-hydroxylation of risperidone and is probably an inhibitor of cytochrome P450 2D6 as are many other phenothiazine drugs.
