 • More than 1500 drugs analysed/characterised • Scoring based on SOP specifically designed • More than 1500 drugs analysed/characterised • Scoring based on SOP specifically designed for each adverse effect • Scoring: • • 0 - No effect 1 - Mild 2 - Moderate 3 - Severe • Over 13000 scores

 • A specific algorithm designed to relate the score to the level of • A specific algorithm designed to relate the score to the level of severity (A-D) for each adverse effect:

 • Standard phrases (easy to translate) for each adverse effect, e. g. anticholinergic • Standard phrases (easy to translate) for each adverse effect, e. g. anticholinergic effect: Consequence There is a high risk for anticholinergic effects such as dry mouth, constipation, urinary impairment or retention, risk of falling, cognitive impairment and confusion. Recommendation The risk is additive. Consider reducing the number of anticholinergic drugs.

 • Decision support for drug use in pregnancy - and lactation - – • Decision support for drug use in pregnancy - and lactation - – Concise understanding on the of the safety of clinically used drugs during different stages of pregnancy and during lactation, including information on: – Clinical, ultrasound, laboratory etc. monitoring – Dosage modification, recommendation on folic acid substitution – Vitamins, micronutrients, illicit drugs – Covers extensively the documentation from the medical literature, manufacturer given information and different national surveillance registers – Same structure as INXBASE has (similar easy integration) – Enables quick comparison of different drug within one drug group to ease the right choice of medication

GFR 10 -50 ml/min (moderate to severe renal failure) using • 1633 drugs were administered to these patients • 15% of prescriptions were not following dosing recommendations • 26 prescriptions were contraindicated • 23% of the study patients received at least one drug that was not dosed in agreement with guidelines • Conclusion: automated decision support is needed to reduce inappropriate prescribing in RF

Classification Degree of renal failure, based on glomerular filtration rate (GFR), is divided into Classification Degree of renal failure, based on glomerular filtration rate (GFR), is divided into four categories, according to the classification by the European Medicines Agency (EMEA): 1. GFR 90 -60 ml/min (mild renal failure) 2. GFR 60 -30 ml/min (moderate renal failure) 3. GFR 30 -15 ml/min (severe renal failure) 4. GFR <15 ml/min (end-stage renal failure; dialysis patient) The safety and need for dosage recommendations is classified into four different categories (A to D), clarified by a colour coding system: A No need for dosage modification The information is not available or the recommendation is estimated based on the B pharmacokinetic characteristics of the substance Modification of the dose or dosage interval is needed C The use should be avoided D For categories B and C, a detailled numerical information on the magnitude of dosage modification is provided whenever available.

Adverse Drug Reactions (ADRs) • • • In 10 -20% of hospitalized patients 7% Adverse Drug Reactions (ADRs) • • • In 10 -20% of hospitalized patients 7% of the whole patient population about 50% of ADRs are severe A-type ADRs B-type ADRs • • • predictable related to known effects of the drug 80 -90% of all ADRs surprising immunological mechanism 10 -20% of all ADRs Allergic reactions • • • Immunological mechanism Can always be repeated Second reaction typically more severe than the preceeding one Pseudoallergic reactions • • • Direct histamine release (morphin) ACE-inhibitor -induced angioedema Not always repeatable, quite common Hypersensitivity reactions to drugs • Cause of hospitalisation in 3 -6% of all patients

 • Hypersensitivity is a common adverse drug reaction • Some of the reactions • Hypersensitivity is a common adverse drug reaction • Some of the reactions are life-threathening • Cross-hypersensivity between drugs is not uncommon • On the other hand some of the cross-reactions which are commonly feared in clinical work (e. g. sulfonamide antibiotics vs. non-antibiotics) are not true and unnecessarily prevent effective drug treatment • Skin tests are often useful in the diagnostic search of alternative treatments to prevent cross-reactions • Alternative drug can be found in most cases
