Drug-related problems among older patients: Analysis of 8 years of pharmacist's interventions.

OBJECTIVES: To analyse the most frequent DRP over time and pharmacists' interventions made among older patients aged over 75 years old. DRP between older patients and younger patients aged 18 to 74 years and between older patients treated in geriatric wards or not were also compared. METHODS: A cross-sectional observational study conducted on DRP detected by pharmacists at the university hospital centre of Lyon and prospectively recorded in the Act-IP© database from January 2008 to December 2015. RESULTS: A total of 56,223 DRP were investigated - 19,056 in older patients and 37,167 in younger patients. A supratherapeutic dosage was mainly reported (22.4% in older patients vs. 19.0% in younger patient) and pharmacists made interventions mostly to adjust dosage (27.3% vs. 24.2%). Physicians' acceptance was significantly lower in older patients (57.1% vs. 64.3%). DRP associated to a drug included a supratherapeutic use of acetaminophen (5.2% vs. 3.8%) and hypnotics (4.0% vs. 1.4%), medication in cardiology used without indication (1.4% vs. 0.2%) and underuse of vitamin D (1.2% vs. 0.1%). Supratherapeutic dosages were more significantly detected with a lower overall physicians' acceptance in older patients treated in general wards. CONCLUSIONS: This study highlights the specificity of DRP among older patients and encourages health care professionals to remain especially alert regarding older patients treated in general wards. These findings can contribute to define or adjust training needs and quality indicators to improve the daily practices of health care professionals.

[Prospective risk analysis in a retrocession unit: Focus on drug dispensation process]. / Analyse des risques a priori en unité de rétrocession hospitalière : focus sur le processus de dispensation.

OBJECTIVES: Failure mode effect analysis (FMEA) improves safety in the drug life cycle. As the drug dispensation by hospital's pharmacy can be at risk, the FMEA tool has been used to evaluate and enhance the process. METHODS: After detailing the process, a first FMEA has been run in 2015. Corrective actions were implemented every time criticality indexes (CI) were above 15. One year later, we have evaluated potential impacts of these actions by running a new FMEA. RESULTS: In 2015, 11 failure modes were prioritized (CI>15) and the total CI for the overall process was 397. Corrective actions were implemented and one year later this amount has decreased by 14% (340) with 6 failure modes still prioritized. Thus, thanks to the FMEA, risks could be identified in year "y", they were taken into account and corrected and then effectively reassessed in year "y+1". CONCLUSION: This study showed us the interest of performing FMEA analysis in the drug dispensation process by hospital. The renewal of this risk analysis after a year helped us to monitor corrective actions, to evaluate their effectiveness and to improve safety. Finally, FMEA seems to be an effective way to steer the drug dispensation process.

[Pharmacist's interventions on outpatient prescriptions in a university hospital drugs sales service]. / Interventions des pharmaciens sur les prescriptions ambulatoires dans le cadre de l'activité de rétrocession d'un centre hospitalier universitaire.

UNLABELLED: For public health reasons, some drugs are only available in hospital drugs sales service. This activity takes place in a specific risk context of organization, patients and/or drugs. A systematic prescription analysis by pharmacist contributes to securise treatment dispensed. The aim of this paper is to present the main drugs problems in the analysis of outpatient prescriptions and pharmaceutical interventions in three units of hospital drugs sales service belong to university hospital. METHODS: Throughout the year 2013, drug problems detected were recorded prospectively and systematically. RESULTS: Of the 22,279 prescriptions analyzed, 247 pharmaceutical interventions (1.1%) were detected including 27.6% of problems concerning the dosages, 15.4% the unconformity, 6.9% contraindications. Regarding ATC drugs classes, we found 43.7% for anti-infectives and 17.4% for antineoplatics. The overall acceptance rate is 81.8%. CONCLUSION: These results show the importance of the analysis of outpatient prescriptions before dispensing and the need to have all prescriptions, clinical and biological elements and to develop interprofessionality. The implementation of a platform for dematerialized data exchanges between professionals, including data from the pharmaceutical patient record should contribute to improving drug management of the patient.

Determination of platinum traces contamination by graphite furnace atomic absorption spectrometry after preconcentration by cloud point extraction.

A simple and sensitive method is described for the determination of platinum surface contamination originating from cisplatin, carboplatin and oxaliplatin. Following extraction from swabs and preconcentration with the cloud point extraction (CPE) method, detection was by graphite furnace atomic absorption spectrometry (GFAAS). After desorption of platinum compounds from the swab, CPE involved on preconcentration of platinum in aqueous solution with diethyldithiocarbamate (DDTC) as chelating agent and Triton X-114 as extraction medium. DDTC is not only a chelating agent, but may also be a good candidate for the inactivation of platinum compounds. DDTC is recommended by the Word Health Organization (WHO) for the destruction of platinum-based anticancer drugs. The main factors affecting CPE efficiency, pH of the sample solution, concentrations of DDTC and Triton X-114, equilibration temperature and incubation time, were evaluated in order to enhance sensitivity of the method. The desorption of platinum compounds from the swab was investigated in parallel. Since platinum is bound to DDTC, it must exchange with copper in order to enhance platinum atomizing by GFAAS. A preconcentration factor of 29 was obtained for 10 mL of a platinum solution at 10 microg mL(-1). In optimal conditions, the limit of detection was 0.2 ng mL(-1), corresponding to 2.0 ng of platinum metal on the swab. Absorbance was linear between 0.7 and 15 ng mL(-1). The proposed method was applied for the determination of surface contamination by platinum compounds with correct results.
