Twelve percent of adults in Sweden have diseases related to their use of medicines. But in four cases of ten it would have been possible to avoid the undesired effects. These are the conclusions of a thesis presented at the Sahlgrenska Academy, University of Gothenburg.
Katja Hakkarainen and her research colleagues have used 7,099 questionnaires and 4,970 patient medical records in Östergötland to map drug-related morbidity. Their work has included side effects, toxicity, the development of drug dependence, the insufficient effect of drugs, and lack of drug treatment.
The study is described in Katja Hakkarainen’s thesis, and shows that 19% of all adults in Sweden report some form of drug-related morbidity, while examination of the medical records gives a figure of 12%.
Two effects were most commonly reported: side effects, and insufficient effect of the drug.
Could have been prevented
At the same time, 20% of those who completed the questionnaire stated that they themselves, healthcare personnel or relatives could have prevented these effects.
Clinical experts who have examined the drug-related morbidity described in the medical records also came to the conclusion that 39%, or four cases of ten, could have been prevented.
“Our results show that drug-related morbidity is a significant public health problem, and that it must be prevented across the whole of the healthcare sector,” says Katja Hakkarainen, pharmacist and researcher at the Sahlgrenska Academy, University of Gothenburg.
Most previous studies in the field have focused on side effects associated with drug use. Katja Hakkarainen’s thesis, in contrast, draws attention to a broader spectrum of drug-related morbidity, including insufficient effects of medicines. The latter effect means, for example, that a potentially active drug has been taken at the wrong dose by the patient, or that it has been prescribed or used wrongly in some other way.
“The studies show that both those treating outpatients and those treating inpatients must become better at recognising drug-related morbidity. Further, new studies should be carried out by scientists, experts in safety and healthcare personnel together to develop preventative strategies,” says Katja Hakkarainen.
The questionnaire study was carried out in 2010, and the medical records were reviewed for year 2008, in collaboration with the Nordic School of Public Health NHV and Linköping University.
The thesis Prevalence and nature of adverse drug events and the potential for their prevention – Population-based studies among adults was successfully defended at a disputation on 21 March, 2014.

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).
Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...
In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.
These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...
Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.
For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...
It comes when called, bringing care utensils with it and recording how they are used: Fraunhofer IPA is developing an intelligent care cart that provides care staff with physical and informational support in their day-to-day work. The scientists at Fraunhofer IPA have now completed a first prototype. In doing so, they are continuing in their efforts to improve working conditions in the care sector and are developing solutions designed to address the challenges of demographic change.
Technical assistance systems can improve the difficult working conditions in residential nursing homes and hospitals by helping the staff in their work and...
