Abstract
1.Introduction
2. Materials and Methods
Data on causes of hospital admissions because of poisoning by antiepileptic, sedative-hypnotic and antiparkinsonism drugs (T42 according to ICD-10) in the years 2006-2012, made available due to courtesy of the public healthcare insurance provider Narodowy Fundusz Zdrowia in Lower Silesia region of Poland (NFZ), were analyzed. The aim of the study was to find out the current incidence and trends in the most common and important intoxications in the analyzed period of time to facilitate the process of toxicology diagnostics for both clinical and forensic medicine purposes.
3. Results And Discussion
In the years 2006-2012 the amount and age structure of the Lower Silesia region of Poland population did not change significantly although there were signs of population ageing [13]. In the year 2014 in the Lower Silesia there were living 2,9 million people,52% of them females [14].
The yearly amount of admissions to hospitals of the Lower Silesia region in the years 2006-2012 that were reported as caused by poisoning by antiepileptic, sedative-hypnotic and anti-parkinsonism drugs without any further specification (T42 according to ICD-10) was alternating, but the general trend was increasing, as it is shown in Figure 1.
Poisonings by hydantoin derivatives (T42.0 according to ICD-10) were alternating from year to year, but there was no distinctive trend in the changes that would be visible in the analyzed period, as it is shown in Figure 2.
The yearly amount of hospital admissions caused by poisonings by iminostilbenes (T42.1 according to ICD-10) dropped significantly in the analyzed period -to 44,1% of its initial value, as it is demonstrated in Figure 3.
Even more pronounced decreasing trend was observed in the amount of admissions to Lower Silesia region of Poland hospitals due to poisonings by succinimides and oxazolidinediones (T42.2 according to ICD-10) - to 16,1% of its initial value, as it is shown in Figure 4.
The yearly amounts of reported hospitalizations due to poisonings by benzodiazepines (T42.4 according to ICD-10) were alternating in the years 2006-2012 in the Lower Silesia region of Poland, but a general decreasing trend was visible. In the end of the analyzed period the amount of hospital admissions dropped to 78,2% of its initial value, as it is demonstrated in Figure 6.
A significant diminishing of the amount of hospital admissions because of poisonings by mixed antiepileptics (T42.5 according to ICD-10) dropped rapidly in the beginning of the analyzed time period and then stayed low, a the level of 36,4% of its initial value, as it is shown in Figure 7.
Poisonings by anti-epileptics and sedative-hypnotic drugs that are not included in the categories T42.0-T42.5 (T42.6 according to ICD-10) showed the raising trend and increased by 28,0% of its initial value, as it is demonstrated in Figure 8.
The yearly amounts of admissions to hospitals of the Lower Silesia region due to poisonings by unspecified anti-epileptic and sedative-hypnotic drugs (T42.7 according to ICD-10) were alternating during the analyzed time period without showing any strongly distinguishable change trend and in its end dropped to 81,5% of the initial value, as it is demonstrated in Figure 9.
The amounts of cases of poisonings by anti-parkinsonism drugs and other central muscle-tone depressants (T42.8 according to ICD-10) among the patients admitted to hospitals in the Lower Silesia region of Poland were alternating in the years 2006-2012 and no strongly pronounced trend was visible in the changes, as it is shown in Figure 10.
4. Conclusion
Emergency medicine, intensive care and anesthesiology specialists taking care of victims of poisonings by antiepileptic, sedative-hypnotic and anti-parkinsonism drugs in the Lower Silesia region of Poland in the years 2006-2012 the amount of hospitalizations because of was stabile, with some positive trends.
The amount of diagnosed intoxications with hydantoin derivatives, anti-parkinsonism drugs and other central muscle-tone depressants remained unchanged in the analyzed period of time, while the amount of admissions due to poisonings by iminostilbenes, succinimides, oxazolidinediones and anti-epileptics needing hospital admission dropped significantly.
Especially optimistic is the decline in hospital admissions due to poisonings by barbiturates and benzodiazepines - it indicates that in the Lower Silesia region of Poland physicians limited in the analyzed time period the scale of prescribing those drugs that have the proven high dependency build up potential and are often used in suicide attempts.
The slight increase in the amount of reported poisonings by not further specified antiepileptic, sedative-hypnotic and anti-parkinsonism drugs and the presence of reported poisonings by unspecified drugs from these groups suggests that there is room for improvement of the toxicological laboratories availability in the Lower Silesia region of Poland. Together with the increase of reported cases of intoxications with untypical anti-epileptics and sedative-hypnotic drugs it indicates also that the emergency medicine and intensive care specialists as well as anesthesiologists could benefit from introduction of more sophisticated analytical methods into screening tests performed by hospital toxicology laboratories that posses the capability of diagnosing broader spectrum of substances.
