[Availability in hospitals of medicines for acute cases]. / Beschikbaarheid van geneesmiddelen in ziekenhuizen bij acute situaties.

Availability in hospitals of medicines for acute cases In acute situations it is important that essential medication is readily available. In this comment we discuss various challenges in determining the assortment of medicines that should be available, and the logistic and administrative obstacles for pharmacists when delivering unregistered medicines such as artesunate. With centralization of (emergency) care, we must ask ourselves whether every hospital pharmacy should have a wide range of medicines in stock. Regional and national agreements on the availability of essential medication for acute situations are essential, and establishing these should be a joint responsibility of physicians and pharmacists.

Intralesional Bleomycin Injections for Vascular Malformations: A Systematic Review and Meta-Analysis.

BACKGROUND: Vascular malformations are congenital anomalies of the vascular system. Intralesional bleomycin injections are commonly used to treat vascular malformations. However, pulmonary fibrosis could potentially be a severe complication, known from systemic bleomycin therapy for malignancies. In this study, the authors investigate the effectiveness and safety of bleomycin (A2, B2, and A5) injections for vascular malformations, when possible relative to other sclerosants. METHODS: The authors performed a PubMed, Embase, Cochrane Central Register of Controlled Trials, and gray literature search for studies (1995 to the present) reporting outcome of intralesional bleomycin injections in patients with vascular malformations (n ≥ 10). Predefined outcome measures of interest were size reduction, symptom relief, quality of life, adverse events (including pulmonary fibrosis), and patient satisfaction. RESULTS: Twenty-seven studies enrolling 1325 patients were included. Quality of evidence was generally low. Good to excellent size reduction was reported in 84 percent of lymphatic and 87 percent of venous malformations. Pulmonary fibrosis was never encountered. Meta-analysis of four studies on venous malformations treated with bleomycin versus other sclerosants showed similar size reduction (OR, 0.67; 95 percent CI, 0.24 to 1.88) but a significantly lower adverse event rate (OR, 0.1; 95 percent CI, 0.03 to 0.39) and fewer severe complications after bleomycin. Symptom relief, quality of life, and patient satisfaction were reported inadequately. CONCLUSIONS: The authors' data suggest that bleomycin is effective in reducing the size of lymphatic and venous malformations, and leads to a lower adverse event rate and fewer severe complications than other sclerosants. The included literature does not provide evidence that pulmonary fibrosis is a complication of intralesional bleomycin injections. This study represents the "best available" evidence; however, only low- to moderate-quality studies were available. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Adherence to HIV therapeutic drug monitoring guidelines in The Netherlands.

BACKGROUND: Therapeutic drug monitoring (TDM) is recommended in several international HIV treatment guidelines. The adherence of clinicians to these recommendations is unknown. The authors evaluated the adherence to the Dutch TDM guideline of 2005. METHODS: From the ATHENA cohort study, three scenarios were selected for which the guideline recommended TDM: 1) start of a combination of lopinavir/ritonavir + efavirenz or nevirapine (drug-drug interaction); 2) start of efavirenz (routine TDM); and 3) use of nelfinavir during pregnancy. For each scenario, we determined the proportion of patients for whom TDM was performed. Multivariable logistic regression modeling was used to identify determinants for the use of TDM. RESULTS: The adherence to the TDM guideline was 46.7% in patients who started lopinavir/ritonavir plus efavirenz or nevirapine; 9.5% for patients who started efavirenz; and 58.5% for patients who used nelfinavir during pregnancy. Patients treated in clinics that had a TDM assay available locally and patients treated in academic clinics were more likely to receive TDM. A higher baseline HIV viral load was another significant predictor for the performing TDM. CONCLUSION: The adherence of clinicians to the Dutch TDM guidelines varied from low to moderate for the three investigated TDM scenarios. This study identifies several determinants for the use of TDM, which may be useful information for those responsible for generating TDM guidelines.
