Use of antimicrobial drugs in developing countries

Pharmacists Views and Practices in Regard to Sales of Antibiotics Without a Prescription in Madinah, Saudi Arabia

OBJECTIVE

The aim of this study was to investigate pharmacists views and practices in Madinah, Saudi Arabia, through conducting direct interviews including direct questions and hypothetical scenarios.

METHODS

A purposeful sample of 150 community pharmacists of different ethnic and educational backgrounds were approached to participate in the study. Semistructured interviews including general questions and 5 hypothetical scenarios were used for the investigation. Complete transcripts of the interviews were prepared. All transcripts were coded and categorized into main themes using a computer software.

RESULTS

Fifty-four pharmacists agreed to participate (response rate, 36%). Sale of antibiotics without prescription is commonly practiced in Saudi Arabia. Lack of legislation enforcement has exacerbated this practice. Economic hardship, patient's age, emotional factors, and pharmacists' self confidence in diagnosing and prescribing medications in general and antibiotics in particular were the themes included in the interviews and influenced pharmacists' decision to sell antibiotics without a prescription.Many pharmacists did not see the practice as a problem and felt capable of continuing to dispense antibiotics without a prescription. Pharmacists who saw the practice as a problem sees legislation enforcement to be the solution of the problem.

CONCLUSIONS

Pharmacist views and practices are alarming. The results of this study show that this practice will continue to spread unless strict enforcement is put in place, Lack of clear understanding of the limitations of pharmacist's scope of practice. Results of these studies can be extrapolated to other countries in the region and other countries of the similar social and professional development status.

A Systematic Review of Antibiotic Prescription Associated With Upper Respiratory Tract Infections in China

Overuse of antibiotics among patients with upper respiratory tract infection (URTI) is a worldwide problem, and the problem is especially serious in developing countries, such as China. This systematic review is aimed at summarizing previous findings on outpatient prescriptions of antibiotics associated with URTI in China in order to help policymakers and the public understand and tackle the problem.We systematically searched and reviewed studies of antibiotic prescribing patterns for outpatients with URTI in China that were published in Chinese or English before December 31, 2014. The study quality was assessed, and the overall rates of URTI cases prescribed antibiotics were calculated by using random-effects model. Subgroup analyses were performed to explore the potential sources of heterogeneity among studies.We included 45 eligible studies with a total of 52,072 URTI outpatients. The overall percentage of URTI outpatients prescribed antibiotics was 83.7% (95% confidence interval [CI]: 80.6%-86.4%). Of the URTI outpatients prescribed antibiotics, 79.7% (95% CI: 72.8%-85.2%) were prescribed 1 antibiotic, 18.4% (95% CI: 13.6%-24.5%) prescribed 2 antibiotics, and 1.1% (95% CI: 0.7%-1.6%) prescribed 3 or more antibiotics. The rates of antibiotic prescription varied greatly across hospitals and showed a downward trend over time.An extremely high percentage of URTI patients in China were prescribed antibiotics and, the overuse is especially problematic in lower-level hospitals. Although there appears a downward trend, likely attributable to China's recent efforts in curbing antibiotic abuse, greater efforts are needed to promote the rational use of antibiotics.

A systematic review of antibiotic utilization in China

OBJECTIVES

Reliable data about antibiotic utilization in the large pharmaceutical market of the world's most populous country, the People's Republic of China, are in short supply. Although many primary studies have investigated the use of antibiotics in China, most of the relevant studies were published in the Chinese language. This systematic review aims to summarize reported percentages of outpatient encounters resulting in the prescription of antibiotics in China.

METHODS

We systematically searched and reviewed studies of antibiotic prescribing patterns in China, published in Chinese or English between 2000 and August 2012. The study quality was assessed and the overall percentage of outpatient encounters resulting in the prescription of antibiotics was calculated using random-effects meta-analysis. Subgroup analyses were conducted to investigate heterogeneity across studies.

RESULTS

We included 57 eligible studies (with a total of 556 ,435 outpatient encounters). The overall percentage of outpatients prescribed antibiotics was 50.3% (95% CI: 47.4%-53.1%). Of the outpatients prescribed antibiotics, 74.0% (95% CI: 71.3%-76.6%) were prescribed one antibiotic, 23.3% (95% CI: 21.1%-25.7%) were prescribed two antibiotics and 2.0% (95% CI: 1.3%-2.8%) were prescribed three or more antibiotics. The proportion of antibiotic utilization differed greatly across hospital levels and geographical regions and fluctuated over time.

CONCLUSIONS

The percentage use of antibiotics is high in China. The excessive use of antibiotics is particularly more problematic in lower-level hospitals and in less developed western China. The implementation and impact of the national efforts to control the excessive use of antibiotics should be appropriately evaluated.

Purchase of Antimicrobials in Retail Pharmacies When a Prescription is Not Required

Objectives: The patterns of purchasing prescription antimicrobials with or without a prescription from retail pharmacies in Ulaanbaatar, Mongolia, were examined in relation to purchasers’ socioeconomic status and price of the product.

Methods: A survey was conducted at 250 randomly selected pharmacies in Ulaanbaatar. A total of 619 customers were interviewed, and the medicines they bought at the stores were examined by medical doctors. The use of prescriptions and advice in purchasing medicines and sociodemographic characteristics of the subjects were determined.

Results: Interviews were conducted with 297 customers who purchased prescription antimicrobials in front of the store in which they made their purchase. Among these 297 customers, only 19.5% (n=58) purchased medicine with a formal prescription, and 37.4% (n=111) purchased medicines on their own initiative and without the guidance of medical professionals. Purchase without a prescription was not associated with the subjects’ gender, age, educational status or area of residence. Lower-priced antimicrobials were purchased without prescriptions more frequently than those with a higher price (P<0.05).

Conclusion: The purchase of antimicrobials without prescriptions is common across all sociodemographic strata in Ulaanbaatar, Mongolia. Considering the increases in number of retail pharmacies and in sales of antimicrobials associated with economic development, measures to enforce regulations and to promote education among the general public and pharmacy professionals are required.

Non-prescription antimicrobial use worldwide: a systematic review

In much of the world antimicrobial drugs are sold without prescription or oversight by health-care professionals. The scale and effect of this practice is unknown. We systematically reviewed published works about non-prescription antimicrobials from 1970-2009, identifying 117 relevant articles. 35 community surveys from five continents showed that non-prescription use occurred worldwide and accounted for 19-100% of antimicrobial use outside of northern Europe and North America. Safety issues associated with non-prescription use included adverse drug reactions and masking of underlying infectious processes. Non-prescription use was common for non-bacterial disease, and antituberculosis drugs were available in many areas. Antimicrobial-resistant bacteria are common in communities with frequent non-prescription use. In a few settings, control efforts that included regulation decreased antimicrobial use and resistance. Non-prescription antimicrobial and antituberculosis use is common outside of North America and northern Europe and must be accounted for in public health efforts to reduce antimicrobial resistance.

Changes before and after a policy to restrict antimicrobial usage in upper respiratory infections in Taiwan

The Bureau of National Health Insurance (BNHI) of Taiwan issued a new reimbursement regulation effective from 1 February 2001 forbidding the use of antimicrobials in ambulatory patients with upper respiratory infections (URI) without evidence of bacterial infection. We evaluated the effect of this regulation by analysing changes in the types of infections diagnosed and the amount of antibiotics prescribed in 1999, 2000 and 2001. Between 1999 and 2001, antimicrobials for respiratory infections decreased from 18.0 to 9.97 DDD/1000 per day or by 44.6% (P=0.0000+). Antimicrobials for URI decreased from 8.32 in 1999 to 3.28 DDD/1000 per day in 2001 or by 60.6% (P=0.0000+); from 2000 to 2001 the decrease was 55.8%. Reduction of antimicrobials for URI from 1999 to 2001 accounted for 62.8% of the reduction of antimicrobials in respiratory infections or 51.3% of the total reduction of antimicrobials. Reduction in aminopenicillins was responsible for most of the decrease.

Antibiotic usage in primary care units in Taiwan

To understand the situation of antibiotic usage in primary care units in Taiwan, we collected all prescriptions over a 1 week period during March 2 to March 7, 1992, December 2 to December 7, 1992, and January 14 to January 19, 1994 from out-patient clinics of public health stations located in various parts of Taiwan. In the first time period 60 health stations were sampled, 18,350 patient-visits made and 23,674 diagnoses recorded. In the second time period 168 health stations were sampled, 84,143 patient-visits made and 96,528 diagnoses recorded. In the third time period 173 health stations were sampled with 85,623 patient-visits and 105,132 diagnoses recorded. The percentages of total patient-visits that resulted in antibiotic treatment were 16.7, 13.5 and 12.4% in the three time periods, respectively. The patient group under the age of 11 received the highest percentage of antibiotic treatment. The percentage of patient-visits that resulted in treatment with two or more types of antibiotics decreased from 25.4% in March, 1992 to 13.2% in January, 1994. Common cold was the most frequent diagnosis in patients receiving antibiotic therapy during the three time periods and accounted for 36.9% of total antibiotic prescriptions. Of the patients with the diagnosis of common cold, 29.7% received antibiotic treatment, of whom the largest group were paediatric patients (< 16 years). Penicillins, macrolides and cephalosporins were the most commonly prescribed antibiotics and accounted for 34.0, 21.8 and 21.3% of all prescribed antibiotics in the three study periods.

Management of fluoroquinolone resistance in Pseudomonas aeruginosa--outcome of monitored use in a referral hospital

We evaluated a strategy designed to improve useful activity of ciprofloxacin against Pseudomonas aeruginosa. Following changes in antimicrobial agent use made by the institutional Pharmacy and Therapeutic Drug Committee, monthly drug usage and microbial susceptibility records from June 1992 through October 1995 were reviewed. From July 1992 through October 1992 (Period 1), ciprofloxacin and ofloxacin usage represented 95 and 5% of total quinolone doses; from December 1992 to March 1993 (Period 2), ciprofloxacin represented 19%; from July 1993 to October 1993 (Period 3), ciprofloxacin usage represented 85%; from July 1994 to October 1994 (Period 4), ciprofloxacin represented 95%; and from July 1995 to October 1995 (Period 5), ciprofloxacin and ofloxacin respectively represented 98 and 2% of total quinolone doses. Comparison of the anti-pseudomonal activity of the two fluoroquinolones to ofloxacin use, ciprofloxacin use and total quinolone use during the entire observational period showed the highest (negative) correlation with ofloxacin use versus ofloxacin activity (y = -15.04x + 1367.99, r2 = 0.06, w = 0.126). Increased use of quinolones plus a change to primarily ofloxacin usage appeared to adversely affect the activity of both ofloxacin and ciprofloxacin against P. aeruginosa.
