[Diffusion of pharmacist interventions within the framework of clinical pharmacy activity in the clinical ward]. / Diffusion des opinions pharmaceutiques dans le cadre d'une activité de pharmacie clinique en unité de soins.

BACKGROUND: Computerised physician order entry (CPOE) and the integration of a pharmacist in clinical wards have been shown to prevent medication errors. OBJECTIVES: The objectives were to describe interventions performed by a clinical pharmacist integrated into clinical wards with CPOE, to assess the acceptance of interventions by prescribers, and to describe factors associated with acceptance. METHODS: A 3-week prospective study was conducted in five wards of a 2000-bed French teaching hospital. RESULTS: During pharmacist review of medication orders and participation on physician rounds, six resident pharmacists provided interventions either conveyed orally to prescribers, using the computer system, or combining both methods. There were 221 pharmacist interventions concerning drug-drug interactions (27%), drug monitoring (17%) and computer-related problems (16%). Pharmacist interventions consisted of change of drug choice or dose adjustment (49%), drug monitoring (17%) and administration modality optimisation (14%). Interventions were provided solely via computer systems in 67% of cases. The rate of intervention acceptance was 47.1%. In multivariate analysis, acceptance was significantly associated with oral transmission (odds ratio [OR] = 6.46; 95% confidence interval [95% CI] [1.65-25.24]; p < 0.01), change of drug choice or dose adjustment recommendations (OR = 3.81; 95% CI [1.63-8.86]; p < 0.01) and administration modality optimisation recommendations (OR = 9.51; 95% CI [3.02-29.93]; p < 0.01). CONCLUSION: Communication method and nature of recommendation are factors associated with pharmacist intervention acceptance. CPOE is necessary to develop clinical pharmacy practice. However, only the integration of the pharmacist on the ward can guarantee a high level of acceptance of pharmacist interventions by prescribers.

Acute pseudoseptic arthritis after intraarticular sodium hyaluronan.

A 70-year-old woman with a history of knee osteoarthritis was admitted for acute arthritis 9 days after a second intraarticular injection of sodium hyaluronan (Ostenil). The joint fluid was purulent, with no crystals, and laboratory tests showed marked inflammation, leading to antibiotic treatment for suspected septic arthritis. Incapacitating symptoms persisted, prompting surgical lavage of the knee, which failed to relieve the severe pain. The persistent symptoms and negative results of joint fluid and blood cultures led to discontinuation of the antibiotic therapy after 10 days. Antiinflammatory therapy relieved the symptoms, and the patient was discharged home 1 month after her admission. Nevertheless, the pain persisted, requiring rehabilitation therapy of the knee. Aseptic arthritis induced by repeated sodium hyaluronan injection is the most likely diagnosis. Physicians should be aware of this extremely severe complication.
