Representative sample survey on factors determining the Czech physicians' awareness of generic drugs and substitution.

BACKGROUND: Generic drugs and generic substitution belong to the tools by which healthcare costs may be reduced. However, low awareness and reluctance among healthcare professionals towards generic drugs may negatively affect the rational use of generic substitution. METHODS: The study aimed to analyze opinions and attitudes towards generic drugs and generic substitution among Czech physicians including their understanding of generic substitution legislative rules and the physicians´ previous experience in this field. Using random allocation, 1551 physicians practicing in the Czech Republic were asked to participate in the sociological representative survey conducted from November to December 2016, through face-to-face structured interviews comprising 19 items. Factor analysis as well as reliability analysis of items focused on legal rules in the context of physicians' awareness were applied with p-value of < 0.05 as statistically significant. RESULTS: Of a total of 1237 (79.8%) physicians (43.7% males; mean age 47.5 ± 11.6 years, 46.3% general practitioners) 24.8% considered generic drugs to be less safe, especially those with specialized qualification (p < 0.01). However, only 4.4% of the physicians noticed any drug-related problems, including adverse drug reactions associated with generic substitution. The majority of physicians felt neutrally about performing generic substitution in pharmacies, nor they expressed any opinion on characteristics of generics, even though a better understanding of the legislation and higher need of accordance of substituted drugs were associated with more positive attitudes towards generic substitution (p < 0.05). Physicians showed low knowledge score of legislative rules (mean 3.9 ± 1.6 from maximum 9), nevertheless they overestimated the law, as they considered some rules valid, even if the law does not require them. Cronbach alpha of all legislative rules that regulate generic substitution increased from 0.318 to 0.553 if two optional rules (physician consent and strength equivalence) would be taken into account. CONCLUSIONS: There is no sufficient awareness of generic drugs and generic substitution related issues among Czech physicians, although a deeper knowledge of legislation improves their perception about providing generic substitution.

Patterns in anticoagulant utilization in the Czech Republic during 2007-2017.

Direct oral anticoagulants (DOACs) have gradually entered the Czech market as alternatives to vitamin K antagonists and parenteral anticoagulants since 2008. Considering the eventual changes, the aim was to evaluate drug use and expenditure patterns on anticoagulants in the Czech Republic. A retrospective utilization study was conducted retrieving data from the State Institute for Drug Control database, including reports on drug supplies from distributors with anatomical therapeutic chemical classification (ATC) codes B01AA, B01AB, B01AE, B01AF, and B01AX. The utilization on national level was expressed as the ratio of the number of defined daily doses per 1000 inhabitants per day (DDD/TID). Expenditures on all anticoagulants were also assessed. Data was analyzed using PASW (version 18.0). Between January 2007 and December 2017, the national anticoagulant utilization rate increased continuously from 14.15 to 27.67 DDD/TID. The use of DOACs was 0.002 DDD/TID in 2008, increased to 6.04 DDD/TID in 2017. Warfarin utilization, after a small decrease in 2008, has shown nearly stable levels in the recent years (70.9% of all anticoagulants; mean 11.55 DDD/TID over the last 5 years), while its increase was halted by the spread of DOACs utilization (p < 0.05). In 2017, over half of the expenditures (51.1%) were due to oral anticoagulants, whereof 47.6% was related to DOACs. The results reflected a growing utilization and increasing costs of all anticoagulants, especially in DOACs at the expense of warfarin. Still, additional information regarding patient persistence and prescribing patterns is needed for a better understanding of oral anticoagulant utilization.

Pulse check as a tool to raise awareness of atrial fibrillation in pharmacies in the Czech Republic - a pilot project.

OBJECTIVE: The aim of the study was to raise the awareness of atrial fibrillation (AF) and the importance of pulse check in Czech pharmacies as well as to point out further possibilities of developing consulting activities in pharmacies. METHOD: Our project was performed as part of a worldwide campaign during three weeks: Heart Rhythm Week (06/2017) and Atrial Fibrillation Awareness Week (11/2017, 11/2018). Pharmacies actively providing indi-vidual counselling offered manual pulse check to patients aged  40 years without chronic anticoagulant therapy. Whenever high risk of AF was observed, patients were referred to a physician for further evaluation. RESULTS: Pharmacists undertook pulse checks in 187 patients (mean age 59.0 ± 12.3 years; 70.6% women) in 14 participating pharmacies. The most common symptoms were fatigue (42.2%) and palpitations (20.9%), however, 40.6% of patients were asymptomatic. The mean heart rate was 73.2 ± 11.3 beats per minute (min. 51; max. 135) and irregular pulse was observed in 4.3% patients. The average CHA2DS2-VASc score was 2.0 ± 1.3. Eight (4.3%) patients were referred to a physician and in 5 patients (2.7%) the arrhythmia was diagnosed. CONCLUSION: Czech pharmacies have successfully adopted this campaign, are interested in continuity of the project and may thus contribute to raise awareness of AF.
