This study aimed to investigate whether TDM-guided voriconazole treat-ment is superior to standard treatment for invasive aspergillosis.Methods: A multicentre ( n = 10), prospective, cluster randomised, crossover clinical trial was performed in haematological patients aged >= 18 years treated with voriconazole. All patients received standard voriconazole dose at the start of treatment. Blood/serum/plasma was periodically collected after treat-ment initiation of voriconazole and repeated during treatment in both groups. The TDM group had mea-sured voriconazole concentrations reported back, with dose adjustments made as appropriate, while the non-TDM group had voriconazole concentrations measured only after study completion. The composite primary endpoint included response to treatment and voriconazole treatment discontinuation due to an adverse drug reaction related to voriconazole within 28 days after treatment initiation. Results: In total, 189 patients were enrolled in the study. For the composite primary endpoint, 74 patients were included in the non-TDM group and 68 patients in the TDM group. Here, no significant difference was found between both groups ( P = 0.678). However, more trough concentrations were found within the generally accepted range of 1-6 mg/L for the TDM group (74.0%) compared with the non-TDM group (64.0%) ( P < 0.001). Conclusions: In this trial, TDM-guided dosing of voriconazole did not show improved treatment outcome compared with standard dosing. We believe that these findings should open up the discussion for an approach to voriconazole TDM that includes drug exposure, pathogen susceptibility and host defence.

Show moreThis thesis aimed to find opportunities to improve proactivity and patient-centredness in palliative care, focussing on education and care outcomes. The 2009 national blueprint on medical education and the Dutch medical curricula did not comprise all essential elements about end-of-life care. Factors associated with approaching death in patients with advanced cancer visiting the LUMC’s Emergency Department (ED) in the last three months of life were lung cancer, neurologic deterioration, dyspnoea, hypercalcemia and jaundice. Patients with haematological malignancies received more potentially inappropriate care than advanced cancer patients. They rarely had limitations on life-sustaining treatments, although they often died of disease progression or treatment toxicity. The surprise question (SQ) is a simple tool to identify patients with palliative care needs . Adding poor performance status to the SQ improved the predictive value for one-year mortality in advanced cancer patients visiting the LUMC’s ED. The Leiden Guide on Palliative Care (LGP) was developed by the Centre of Expertise in Palliative Care to assess symptom burden and information needs. Patients and family wanted information about current problems and about their worries. Patients, family and clinicians found the LGP helpful. Using their input, the LGP was improved for use by generalist palliative care clinicians. Show less
