[Targeting anticoagulated patients for medication reconciliation at discharge in orthopaedic surgery]

In orthopedic surgery, the well-known iatrogenic risk of oral anticoagulants is particularly increased due to surgical management (suspension and resumption of treatment). In order to prevent avoidable iatrogenic events linked to incomplete discharge documents, targeted medical reconciliation (MR) has been deployed. This is a single-center prospective study conducted in orthopaedic surgery for six months including any patient treated upon admission with an oral anticoagulant. The analysis of the compliance of discharge documents (hospitalization report and prescriptions) was carried out before and after pharmaceutical interventions. The criteria analysed included the mention of the oral treatment, its dosage as well as the supervision of the switch from heparin therapy to the usual oral treatment. The documents were compliant if the mention of oral anticoagulant treatment and the date of the shift were correctly documented. Thirty-seven patients were included. The compliance rate of discharge documents was significantly improved by MR, going from 13.5 % to 78.4 % (P <0.05). The non-compliances before the intervention concerned the absence of mention of: the usual treatment (64.9 %), its dosage (81.1 %) or the switch's securing (75.7 %). Discharge from surgery of the patient on anticoagulants is a stage presenting a real risk which can be managed by the intervention of pharmacists. Improving the compliance of discharge documents is a first step towards better securing drug management.

[Pharmaceutical cares as means of prevention against drug iatrogenic: Case of oral anticoagulant]

Oral anticoagulant can have a significant risk of adverse events, particularly when it is initiated, modified or interrupted. Pharmaceutical care through medication reconciliation could improve the benefit-to-risk ratio of these drugs. A prospective and interventional single center study was conducted from March through August 2018 in medicine and surgical units. Patients with an oral anticoagulant prescribed and coming from outpatient sector were included. These patients received a medication reconciliation at admission and discharge. Frequency and type of discrepancies were studied. Their gravity rating was assessed using the Cornish et al. scale. This study included 162 patients. The medication reconciliation at the admission allowed the detection of 133 unintentional discrepancies which 16 of them represented a high risk for the patient included nine errors about oral anticoagulant prescribing. Concerning the reconciliation at discharge, 51 unintentional discrepancies had been detected: 12 of them represented a high risk for the patient included eight errors about oral anticoagulant prescription. The acceptance rate of the discrepancies was 86% and reflected discrepancies severity. This result reached 96.4% if we took into account discrepancies with a severe clinical impact. This study highlighted oral anticoagulant represented relevant prioritization criteria to the long-lasting implementation of pharmaceutical care. This secures the management of the patient since the admission until the hospital discharge. The last step of our approach would be to study the needs about data transmission to the community caregivers.

[Direct oral anticoagulants: In which indications? Which one to prescribe? For or against their use in frail patients and in atypical cases? Which monitoring and management haemorrhage complications?]

Since their approval, the direct oral anticoagulants have been widely used in the management of venous thromboembolism, for stroke and systemic embolism prevention in non valvular atrial fibrillation, and in venous thromboembolism prophylaxis after surgical hip or knee replacement. Because they are easy to use, with oral fixed doses and no biological monitoring need, they are more and more prescribed. New indications are rising in cancer associated thrombosis in France beyond the 6 first months of treatment, and to prevent cardiovascular events after an acute coronary syndrome, or in stable coronary or peripheral arterial disease in Europe. The efficacity and safety of direct oral anticoagulants in frail patients or in unusual pathological contexts are not entirely known, but further data are coming and will probably bring new answers.

[Anticoagulation in the aged patient with atrial fibrillation: What are prescribing cardiologists, geriatricians and general practitioners?]

OBJECTIVE

To assess prescribing of anticoagulants in atrial fibrillation (AF) in the elderly, both a quantitative point of view (rate of anticoagulation) and qualitative (type of anticoagulation). Determinants of prescribing and non-prescribing were also analysed.

METHODS

Prospective survey of practice, based on one clinical case and questionnaire conducted in 60 practitioners (20 cardiologists [C], 20 geriatricians [G] and 20 general practitioners [GP]).

RESULTS

In reading the clinical case, 88.3% of physicians would have initiated a treatment; three types of treatments would have been chosen: AVK (68.3%), ODA (20.0%) and platelet antiaggregant (11.7%). Criteria taken into account to initiate anticoagulation varied according to the specialty. Cardiologists considered more the age criteria (C: 95.0%, G: 75.0%, MG: 60.0%; P<0.05), diabetes (C: 90.0%, G: 60.0%, MG: 55.0%; P<0.05), hypertension (C: 85.0%, G: 55.0%, MG: 60.0%; P<0.05) and female gender (C: 80.0%, G: 35.0%, MG: 25.0%; P<0.05). The quality of renal function was however a more secondary criteria (C: 15.0%, G: 5.0%, MG: 0.0%; P<0.05). General practitioners considered most frequently the presence of underlying heart disease (C: 35.0%, G: 5.0%, MG: 45.0%; P<0.05) as well as usual cardiovascular risk factors (overweight, dyslipidaemia; P<0.05). Risk of bleeding, however, was observed by 76.7% of physicians in the clinical situation presented (C: 70.0%, G: 75.0%, MG: 85.0%; P<0.05).

CONCLUSION

This survey confirms that the FA remains under anticoagulated in the elderly and the barriers to the prescription of oral anticoagulation are often without rational basis.
