Antimicrobial drug use in hospitalised paediatric patients: a cross-national comparison between Germany and Croatia.

PURPOSE: To compare the utilisation of systemic antimicrobials at the paediatric units of the university hospitals in Marburg (Germany) and Rijeka (Croatia). METHODS: A prospective, observational analysis of hospital records from 300 incident users of antimicrobials in each study centre that were younger than 19 years. Antimicrobial utilisation was analysed in six gender-specific age groups with respect to drug choice, duration of treatment and hospital stay, indication and route of administration. The extent of antimicrobial drug use was assessed by the number of treatment courses. RESULTS: In each hospital, more than 1/3 of the patients were younger than 1 year. The duration of hospital stay was about two-fold longer in Rijeka (18.5 +/- 5.8 days) than in Marburg (8.6 +/- 3.8 days). Pneumonia and other respiratory tract infections were the most common indications in Marburg (38.6%) and Rijeka (58.7%). The cumulative percentage of patients treated with an equal number of different antimicrobials was lower in Rijeka than in Marburg. The most commonly used antimicrobials were ampicillin (40.3%) and cefuroxim (35.9%) in Marburg, but ceftriaxone (43.3%) and cefotaxim (14.0%) in Rijeka. CONCLUSIONS: A shorter treatment duration, less variation in the prescribing pattern and a greater adherence to the use of recommended antimicrobials argue for a more rational antimicrobial drug use in Marburg than in Rijeka. However, a further identification of drug choice determinants is warranted.

Analysis of antiepileptic drugs use at a university hospital in Croatia.

To analyse the consumption rate of new generation antiepileptic drugs (AEDs) compared with traditional AEDs at a university hospital in Croatia. Antiepileptic drugs use was analysed retrospectively for two consecutive years, 2001 and 2002 at Departments of Neurology, Paediatrics, Psychiatry and Neurosurgery at the University Hospital Centre (UHC) Rijeka. The results obtained are expressed as number of defined daily doses (DDDs) per 100 bed days, as proposed by the WHO. The use of new generation AEDs was represented by 2% in 2001 and 5% in 2002. Majority of AEDs administered was taken by the barbiturates in both years. A wide spectrum of AEDs has been used at the Department of Paediatrics. At the Department of Neurology and Psychiatry use of barbiturates and carbamazepine predominated. The use of new AEDs at UHC has increased during the investigation period but it is still rather low compared with traditional AEDs. The similarity of our results with the result of the leading Croatian university hospitals might represent general routine AED prescription in country. Nationally based guidelines may bring more appropriate and rational approach for usage of modern AED. This task should be supported and promoted by international and national neurology associations.

Factors influencing antimicrobial utilization at a university hospital during a period of 11 years.

OBJECTIVE: A number of factors may influence antibiotic prescribing. The objective of this study was to identify trends in antimicrobial prescribing during a period of 1 years at the University Hospital Center Rijeka (UHC), Croatia, and to identify possible factors that might have influenced changes in prescribing patterns. This may help in establishing criteria for future intervention. METHODS: Antimicrobial utilization was evaluated retrospectively for the 11-year period from 1990-2000. It was measured in defined daily doses (DDDs) per 100 bed days using the ATC Index with DDDs 2000. RESULTS: During the investigation period, marked differences were noted in total and individual antimicrobial consumption. In the first 4 years of this study, the utilization of all groups of antimicrobials decreased, while in its second part (i.e. from 1995-1997) an increase in utilization of all antimicrobial groups occurred. Changes in utilization of groups of antimicrobials did not coincide completely with the changes in total antimicrobial utilization. The most prominent changes were a decrease in penicillin and cephalosporin utilization, and an increase of macrolides and aminoglycosides utilization from 1997-2000. Ampicillin and cefalexin were mostly prescribed as single antibiotics during a 5-year period (1990-1995) with the exception of 1 year (1994) when a marked decline in antimicrobial utilization was noted. In the following years, amoxicillin and amoxicillin with enzyme inhibitor became the most-used antimicrobials. CONCLUSION: Various factors influenced antimicrobial utilization during the investigation period. There were factors that directly influenced prescribing, e.g. the physicians' prescribing habit, guidelines, policy and formulary. Other factors directly influenced utilization, e.g. availability of a drug through purchasing, dispensing, procurement, pricing etc.

Antimicrobial utilization and bacterial resistance at three different hospitals.

It has been generally recognized that the prevalence of bacterial resistance among bacteria is an unavoidable consequence of antibiotic use and is positively linked to the overall use of antibacterial drugs. The purpose of this study was to investigate the extent of antimicrobial usage and to evaluate the antimicrobial resistance at three different hospital settings in Croatia: a clinical hospital, a general hospital and a specialized clinic for infectious diseases. In this survey the antimicrobial drug consumption and antimicrobial susceptibility test results were analyzed for the first 6 months of 1997 in three different hospitals in Croatia: the University Hospital Center (UHC), Rijeka, the Clinic for Infectious Diseases 'Dr Fran Mihaljević', Zagreb and the Dubrovnik General Hospital. The data were collected from corresponding hospital pharmacy records and microbiology laboratories. Antimicrobial drug utilization was expressed in number of defined daily doses (DDDs) per 100 bed days. High antimicrobial utilization and high resistance rates were found in all three hospitals. At the Clinic for Infectious Diseases, the most frequently used antimicrobials where those of narrow spectrum while at the UHC Rijeka and the Dubrovnik General Hospital the broad spectrum antimicrobials were mostly used. The highest antimicrobial consumption was noted at the Susak locality of the UHC, Rijeka, where the highest resistance rates of bacteria to antimicrobials were also found. Results of this observational study indicate that attempts should be made to reduce the influence of factors that may lead to emergent resistance. The most effective approach to the prevention of transmission of multidrug-resistant pathogens is preventing the initial emergence of resistance. A rational and strict antibiotic policy is thus of great importance for the optimal use of these agents.

Antibiotic utilization at the university hospital after introducing an antibiotic policy.

OBJECTIVE: Antibiotic formulary restrictions are among the most popular methods to control antibiotic utilization in hospitals. The aim of the present survey was to investigate the influence of "reserve antibiotic" on antimicrobial utilization at the University Hospital Center (UHC) Rijeka. METHODS: At the UHC Rijeka, reserve antibiotic was implemented in July 1997. The antimicrobial drug consumption was monitored 6 months prior to and 6 months after the introduction of the method. Antimicrobial consumption was measured in defined daily doses (DDDs) among the major clinics. RESULTS: Reserve antibiotic has led to a decrease in total antibiotic consumption at the UHC Rijeka (45.9 DDDs/100 bed days vs 32.9 DDDs/100 bed days). Antibiotic utilization decreased in the second semester at most clinics: at the Clinic for Infectious Diseases 41%, at the Anesthesiology and Intensive Care Unit 30%, at the Clinic for Internal Medicine 18% and at the Surgical Clinic 12%. At the Clinic for Gynecology and Obstetrics, the antibiotic utilization remained the same, while at the Pediatric Clinic an increase of 28% in antibiotic utilization was noted. CONCLUSION: Our study indicates that restriction of usage of some antibacterial agents is a successful method to decrease antibiotic consumption and a way to bring cost savings and helps prevent emergence of resistant microorganisms in hospitals. To improve antimicrobial prescribing, additional methods such as education are required.

Antibiotics utilization during the war period: influence of drug donations.

The purpose of the present study was to investigate the antibiotics utilization in the University Hospital Center of Rijeka (UHC), with capacity of 1566 beds, during the period of 4 years (1990-1994). The data concerning the antibiotics utilization were collected from a hospital pharmacy record and calculated as the defined daily dose (DDD) per 100 bed days. Total antibiotics use decreased continually from 1990 through 1994. According to our study, metronidazole became the most frequently prescribed antibiotic. Comparing the 1994 to the 1990 antibiotics utilization, we may notice an outstanding decrease in cotimoxazole, ampicillin and cefalexin utilization and an increase in amoxicillin + clavulanic acid, gentamycin and cefuroxime (there are no tetracyclines among the 10 most frequently prescribed antibiotics). The changes noticed in the use of antibiotics are partly caused by changes in therapeutic principles, but we consider drug donations as the most important factor. Drug donations have retained the treatment quality of our patients in very difficult conditions in Croatia during the war period.

[Onset of menarche in Skopje. (Comparative studies on 22,727 women up to the 6th decade of age)].

Studies of menarche in Skopje have shown that its secular trend is significantly more pronounced in younger than in older generations. While in the young it amounts to 2.5--3 months per decade, in the elderly it is up to one month per decade. The total acceleration in the course of this century has proved to be 13.5 months. The earliest menarche was recorded in Romanies (13.46 +/- 0.92), the latest in Albanians (14.05 +/- 1.22), while Macedonian girls are somewhere in--between, along with other nationalities (14.0 +/- 1.40). Menarche proved to appear earlier in girls from very well-to-do families (13.95 +/- 1.36) than in those from families with a very low income (14.19 +/- 1.43). The latest beginning of the menstruation has been recorded in girls from peasant families (14.38 +/- 1.17). Sporadic repeated investigations of this king in different parts of the country, by using a more modern "status quo" method, appear necessary in order to determine differences in the menarcheal age in the country as a whole and to shed more ligh on their underlying causes.
