Longitudinal surveillance of antibiotic use in the hospital
QJM, 2001
We evaluated antimicrobial use in our hospital by department, including indications for use, source of infections, use of the microbiology laboratory, and appropriateness of prescribing, in a prospective, comparative, non-interventional study of all patients receiving antimicrobial agents. We excluded departments where antimicrobial use was negligible. The other 19 departments were followed for 3 (n = 4) or 4 (n=15) months, including 2 consecutive months in the spring-summer and either 1 or 2 in the autumn-winter. Antimicrobial therapy was followed from initiation, through possible adaptations, and possible change from intravenous to oral therapy, until discontinuation of treatment. Overall, 6376 antibiotics were given to 2306 patients. Of the surveyed hospitalized patients, 62%"22% received antibiotics, with a range of 4±100% per department. Antibiotics were prescribed for infections acquired in the community (3037 instances, 47%), in the hospital (2182, 34%), in a nursing home (575, 9%), and for prophylaxis continued post-operatively (582, 9%). The most common indications for antimicrobial use were: respiratory tract infection (1729, 27%), urinary tract infection (955, 15%), sepsis (701, 11%), intra-abdominal infections (663, 10%), prophylaxis 582 (9%), soft-tissue infection (572, 9%), and surgical site infection (319, 5%). Univariate indicators for appropriateness of treatment were: age, department, site of infection, source of infection, antimicrobial drug and serum creatinine (all p-0.001). Forty-nine antimicrobials were prescribed in 279 combinations, 58% as single agent and 42% as drug combinations. Half of all antimicrobial use consisted of four agents: cefuroxime (19.1%), metronidazole (11.3%), gentamicin (10.6%) and ampicillin (10.2%), which together accounted for 20% of expenditure on antibiotics. Although use of as many as 53% of antimicrobials (26/49) surveyed was restricted, use in this category accounted for only 29% of all antimicrobial courses. Of 6376 antibiotic courses, 4101 (64%) were given intravenously and 2275 (36%) orally. Appropriateness of use of restricted drugs was lower (70%) than of unrestricted ones (84%, p-0.001). Of 24 571 defined daily doses (DDD) given orally, 4587 (19%) were restricted, compared to 7264 (34%) of 21 602 DDDs given intravenously (p-0.001). Antibiotic treatment in our hospital appears to be substantial and increasing, justifying efforts to improve appropriateness of therapy and improve clinical and financial results.
Assessment of Antibiotic Utilization Pattern In Hospital Settings
International Journal of Research in Pharmaceutical Sciences
Drug utilization evaluation is an effective tool for detecting the possible drug related problems and in enhance the clinical use of drugs in public and its impact on the health care system. This tool is adapted by pharmacists to assess appropriate use of medication. DUE usually focus on drugs with more side-effects, high cost or complex dosing regimens. It is important for almost all drugs especially for antibiotics because of its increased utilizationin hospitals and community settings. In prior to starting antimicrobial therapy, the prescriber should consider the type of infection, characteristics of the antibiotic, its category of use, spectrum of activity, cost- effectiveness and duration of therapy. The evolution of multidrug resistance and the emergence of multidrug- resistant microbes are on the rise which can be reduced by increasing the habits of appropriate antibiotic prescribing for the successful outcome of the therapy. Prescribing an antibiotic by understanding the sig...

Surveillance data of antibiotic use are increasingly being used for benchmarking purposes, but there is a lack of studies dealing with how hospital- and patient-related factors affect antibiotic utilization in hospitals. Our objective was to identify factors that may contribute to differences in antibiotic use. Based on pharmacy sales data (2006-2011), use of all antibiotics, all penicillins, and broad-spectrum antibiotics was analysed in 22 Health Enterprises (HEs). Antibiotic utilization was measured in World Health Organisation defined daily doses (DDDs) and hospital-adjusted (ha)DDDs, each related to the number of bed days (BDs) and the number of discharges. For each HE, all clinical specialties were included and the aggregated data at the HE level constituted the basis for the analyses. Fourteen variables potentially associated with the observed antibiotic use - extracted from validated national databases - were examined in 12 multiple linear regression models, with four differ...

Objectives: Antibiotic use in French hospitals is among the highest in Europe. A study was carried out to describe antibiotic consumption for inpatients at hospital and at ward levels. Methods: Data were voluntarily collected retrospectively by 530 hospitals accounting for 40 million patientdays (PD) on the following: antibacterials for systemic use [J01 class of the WHO Anatomical Therapeutic Chemical (ATC) classification, defined daily doses (DDD) system, 2007], rifampicin and oral imidazole derivatives, expressed in number of DDD and number of PD in 2007. Consumption was expressed in DDD/1000 PD. Results: Median antibiotic use ranged from 60 DDD/1000 PD in long-term care (LTC) and psychiatric hospitals to 633 DDD/1000 PD in teaching hospitals. Penicillins and b-lactamase inhibitors combinations were the most frequently used antibiotics, accounting for 26% of total use in cancer hospitals to 40% in LTC/psychiatric hospitals. Glycopeptides and carbapenems were mostly used in cancer and teaching hospitals. Level of consumption and pattern of use differed according to clinical ward from 60 DDD/1000 PD in psychiatric wards up to 1466 DDD/ 1000 PD in intensive care units (ICUs). In medicine, surgery, ICU and rehabilitation wards, fluoroquinolones accounted for 13%-19% of the total use. Conclusions: This multicentre survey provided detailed information on antibiotic use in a large sample of hospitals and wards, allowing relevant comparisons and benchmarking. Analysis of consumption at the ward level should help hospitals to target practice audits to improve antibiotic use.
A Retrospective Study on Antibiotic Usage in a Tertiary Care Hospital
International Journal of Medical and Biomedical Studies
Antibiotics are one of the most commonly prescribed drugs today. Rational use of antibiotics is therefore extremely important as their injudicious use can adversely affect the patient. Drug Utilization Evaluation (DUE) is a system of ongoing systematic criteria based evaluation of drug that will help to ensure that medicines are used appropriately. It is drug/disease specific and can be structured so that it will assess the actual process of prescribing, dispensing, or administration of drug. The retrospective study was conducted At Pk Das Institute of Medical Sciences, Palakkad, Kerala for a duration of 6 months (February 2017 - January 2018). A source of data includes Patient case sheets &medication charts, nursing charts, culture & sensitivity reports. The inclusion criterion includes Patients aged between 18- 80 year, prescribed with oral and parenteral antibiotics. . On analyzing the gender, male gender (n= 111, 55.5%) were higher in numbers as compared to female counterparts (...
Estimating National Trends in Inpatient Antibiotic Use Among US Hospitals From 2006 to 2012
JAMA internal medicine, 2016
The rising threat of antibiotic resistance and other adverse consequences resulting from the misuse of antibiotics requires a better understanding of antibiotic use in hospitals in the United States. To use proprietary administrative data to estimate patterns of US inpatient antibiotic use in recent years. For this retrospective analysis, adult and pediatric in-patient antibiotic use data was obtained from the Truven Health MarketScan Hospital Drug Database (HDD) from January 1, 2006, to December 31, 2012. Data from adult and pediatric patients admitted to 1 of approximately 300 participating acute care hospitals provided antibiotic use data for over 34 million discharges representing 166 million patient-days. We retrospectively estimated the days of therapy (DOT) per 1000 patient-days and the proportion of hospital discharges in which a patient received at least 1 dose of an antibiotic during the hospital stay. We calculated measures of antibiotic usage stratified by antibiotic cla...
