Outcomes of an antimicrobial control program in a teaching hospital.

The clinical outcomes and cost-effectiveness of an antimicrobial control program (ACP) were studied. The impact of an ACP in a teaching hospital was analyzed by comparing clinical outcomes and intravenous antimicrobial costs over two two-year periods, the two years before the program and the first two years after the program's inception. Admission baseline data, length of stay, mortality, and readmission rates were gathered for each patient. Patients were identified by using the International Classification of Diseases. Multivariate logistic regression models were constructed for mortality and for lengths of stay of 12 or more days. The acquisition costs of intravenous antimicrobial agents for the second baseline year and the entire program period were tabulated and compared. The average daily inpatient census was determined. The ACP was associated with a 2.4-day decrease in length of stay and a reduction in mortality from 8.28% to 6.61%. Rates of readmission for infection within 30 days of discharge remained about the same. Inpatient pharmacy costs other than intravenous antimicrobials decreased an average of only 5.7% over the two program years, but the acquisition cost of intravenous antimicrobials for both program years yielded a total cost saving of $291,885, a reduction of 30.8%. The institution's average daily census fell 19% between the second baseline year and the second program year. An ACP directed by a clinical pharmacist trained in infectious diseases was associated with improvements in inpatient length of stay and mortality. The ACP decreased intravenous antimicrobial costs and facilitated the approval process for restricted and nonformulary antimicrobial agents.     

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.     

Home intravenous antimicrobial therapy provided by a community hospital and a university hospital

A home intravenous antimicrobial program that was implemented at both a private community hospital and a university hospital with a wide rural referral base is described. Over an 18-month period, 63 patients were screened and selected for home i.v. antimicrobial management according to stringent criteria. The hospital pharmacies and two home health-care companies were used as the central points for coordinating the preparation and distribution of drug products and providing specialty nursing services. Predischarge inhospital education for each patient was conducted by a pharmacist and a nurse. On-call pharmacists and nurses were available to monitor and assist the patients, and the patients were seen regularly by physicians during the period of home therapy. The 63 patients received a total of 1108 days of home i.v. antimicrobial therapy; the mean duration of therapy was 17.6 days. Heparin-lock peripheral cannulae were used for 51 patients, while 12 patients received their treatment through central-subclavian or Hickman catheters. Home i.v. antimicrobial treatment seemed to be as effective as comparable inpatient management for each type of infection. Drug- and i.v. catheter-related adverse effects were uncommon and seemed similar in type and frequency to those of hospitalized patients. The estimated cost savings per treatment course was $3,514 for a total net savings of $221,406 over the 18-month study period. Home i.v. antimicrobial treatment programs can be successfully implemented in both community-based and tertiary-care settings. Home therapy is a safe, efficacious, and cost-effective alternative to prolonged hospitalization for a variety of infectious diseases.     

Compliance with a restricted antimicrobial agent policy in a university hospital

Compliance with a policy for use of antimicrobial agents that requires both oral approval from the infectious diseases service and completion of a restricted antimicrobial agent use form was evaluated in a 950-bed teaching hospital. The charts of patients for whom a restricted antimicrobial agent was ordered during four one-week periods between January 1987 and April 1987 were audited to determine whether completed use forms had accompanied orders for restricted antimicrobial agents. The validity of the information on completed forms was determined by comparing the information on the form with notes in patients' charts and through discussions with infectious diseases physicians. Two infectious diseases physician reviewers evaluated the appropriateness of prescribing of piperacillin and ceftazidime by analyzing data collected by pharmacists. Forms were submitted with 132 of 154 orders written for restricted agents; incomplete forms were received and accepted by pharmacists for 39 courses of therapy. The infectious disease service had not been contacted to approve use of a restricted agent in 25 cases. Eight of the 48 courses of piperacillin or ceftazidime therapy were deemed inappropriate despite initial infectious diseases approval. Compliance with a formal antimicrobial agent restriction policy at this institution has been good, but periodic re-education and follow-up monitoring appear to be necessary to ensure optimal use of restricted agents.     

Utilization of fluconazole in an intensive care unit at a university hospital in Brazil

Background Fungi have been developing resistance and merit greater attention because these microorganisms are among the major causes of hospital infection. Objective The aim of the present study was to characterize the pattern of fluconazole use in an adult intensive care unit. Setting The setting was an intensive care unit at a university hospital in Brazil. Method An observational retrospective study was performed between 2007 and 2010. The use of antifungal drugs was calculated as the defined daily dose per 1,000 patient-days. The pattern of fluconazole use was determined by analyzing patient charts. Results Fluconazole accounted an average of 66.6 % of the antifungal agents prescribed. All of the patients exhibited important risk factors for the development of fungal infection. Treatment was empirical in 45.2 % of the cases and therapeutic in 54.8 % of the cases. The dose interval was inadequate in 51.1 % of the treatments. Fluconazole at doses ≥400 mg/day was related to a greater likelihood of survival. C. albicans was the most prevalent species (31.3 %). Urine was the biological material with the greatest number of positive mycological exams (71.9 %). Conclusion This study found a high utilization of fluconazole and, in most cases, its administration at intervals that were different from the recommended intervals.     

Relationships between antimicrobial use and antimicrobial resistance in Gram-negative bacteria causing nosocomial infections from 1991-2003 at a university hospital in Taiwan

This study was conducted to evaluate the relationship between antimicrobial resistance and antimicrobial use in a university hospital in Taiwan. Disk susceptibility data of Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Serratia marcescens, Proteus spp., Pseudomonas aeruginosa, Acinetobacter spp., Stenotrophomonas maltophilia and other non-fermentative Gram-negative bacilli causing nosocomial infections were evaluated. Data on annual patient-days and annual consumption (defined daily dose (DDD) per 1000 patient-days) of extended-spectrum cephalosporins (cefotaxime, ceftriaxone, ceftazidime, flumoxef, cefepime and cefpirome), β-lactam–β-lactamase inhibitor combinations (ticarcillin/clavulanic acid and piperacillin/tazobactam), carbapenems (imipenem and meropenem), aminoglycosides (amikacin, gentamicin and tobramycin), fluoroquinolones (ciprofloxacin (oral and injectable) and oral levofloxacin and moxifloxacin) from 1991 to 2003 were analysed. Increasing trends of incidences of several of these bacteria causing all nosocomial infections or nosocomial bloodstream infections were noted from 1991 to 2003. The annual patient-days of the hospital significantly increased, from 360 210 in 1991 to 672 676 in 2002 (linear regression analysis, P < 0.05), but slightly decreased in 2003 (629 168) owing to the severe acute respiratory syndrome epidemic in Taiwan. The rise in cefotaxime-resistant or ciprofloxacin-resistant E. coli and meropenem-resistant P. aeruginosa was significantly correlated with increased consumption of extended-spectrum cephalosporins, β-lactam–β-lactamase inhibitor combinations, carbapenems, fluoroquinolones and aminoglycosides (for ciprofloxacin-resistant E. coli and meropenem-resistant P. aeruginosa only) in the hospital (Pearson's correlation coefficient, r > 0.72 (or <−0.72) and P-value < 0.05). Increased ciprofloxacin-resistant K. pneumoniae and meropenem-resistant Acinetobacter spp. was significantly associated with the increased usage of extended-spectrum cephalosporins but not with the other four classes of antibiotics. This 13-year study in a hospital demonstrated significant changes in antimicrobial use, which may have affected antimicrobial resistance in certain Gram-negative bacteria at the hospital.     

The anaesthetist as determinant factor of quality of surgical antimicrobial prophylaxis. A survey in a university hospital.

In actual surgical antimicrobial prophylaxis, the anaesthetist administers the drugs at induction of anaesthesia. In the first phase of our qualityofuse intervention study on antimicrobial drugs in a large university hospital, information on the practice of antimicrobial prophylaxis was needed. The staff of 44 anaesthetists was interviewed by means of a questionnaire. Response rate was 36/44 (82%). The anaesthetists' method of administering surgical prophylaxis was rather uniform and inexpensive: cephalosporins were almost exclusively administered by bolus method. The main reason was that infusion was more cumbersome (range 7785%). Communication between surgeon and anaesthetist was reported to be poor, and in two out of three operating departments, orders of prophylaxis transmitted at or after induction accounted for more than 80%. Seventyseven percent of the responders asked the surgeon if prophylaxis was necessary if they were in doubt; 20% responded that they checked it systematically. The data collected by the inquiry proved useful in the process of optimizing surgical prophylaxis in our hospital.     

The effect of an antimicrobial restriction program on Pseudomonas aeruginosa resistance to beta-lactams in a large teaching hospital

STUDY OBJECTIVES: To compare the use of beta-lactams and subsequent Pseudomonas aeruginosa sensitivity patterns before and after implementation of a clinical pharmacist-facilitated antimicrobial restriction program in August 1997. DESIGN: Retrospective consecutive data collection. SETTING: Large university-affiliated medical center. INTERVENTION: The study results are the accumulation of the daily intervention activities of the antimicrobial restriction program. Data on antimicrobial grams purchased/1,000 patient-days and susceptibility patterns were collected and analyzed retrospectively. MEASURES AND MAIN RESULTS: Annual grams of ceftazidime, piperacillin, piperacillin-tazobactam, and other antipseudomonal beta-lactams purchased/1,000 patient-days were compared during the 2 full calendar years before the antimicrobial restriction program (1995-1996) with the 4 full calendar years after the program was implemented (1998-2001). Pseudomonas aeruginosa resistance trends for the antipseudomonal beta-lactams, ciprofloxacin, and tobramycin also were compared for the 2 years before the program (1995-1996) with the last 2 years of the program (2000-2001). A 44% reduction in ceftazidime use was documented; ostensibly, minimal changes occurred in the overall use of piperacillin and piperacillin-tazobactam. During the same time period, ceftazidime resistance fell from 24% to 11.8% (p<0.001), whereas piperacillin resistance fell from 32.5% to 18.5% (p<0.001). Imipenem resistance declined from 20.5% to 12.3% (p<0.001) with an 18% reduction in use. Aztreonam resistance declined from 29.5% to 16.5% (p<0.001) despite a 57% increase in use. No changes in resistance to either ciprofloxacin or tobramycin were found. CONCLUSION: Through an antimicrobial restriction program, a dramatic reduction in ceftazidime use was achieved with judicious use of other antipseudomonal antimicrobials, which resulted in reduced resistance of P aeruginosa to other beta-lactams.     

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. Received: 28 October 1999 / Accepted in revised form: 26 January 2000

Development and implementation of a strategic-planning process at a university hospital

The development and implementation of a long-range strategic plan for the pharmacy department at a university hospital is described. Because of rapidly occurring changes in health-care delivery, financing, and education, the pharmacy department at the University of Illinois Hospitals decided to create a strategic plan that would stimulate growth, be responsive to a changing health-care environment, and emphasize the department's philosophy of striving for professional leadership in education, research, and innovation. Actual strategy development was done during a three-day administrative retreat, which was conducted according to a structured agenda that facilitated extensive brainstorming and discussion. As a result, the department developed eight major strategies that have been directing its growth and development over the last four years. Each strategy had an implementation plan that included substrategies with statements of specific results that were expected, an action plan (a list of specific tasks to be accomplished), and a general statement summarizing the benefits of each substrategy. Annual meetings were held to review the continued appropriateness of these strategies. Implementation of the strategic plan has resulted in major improvements in drug cost containment, improved ambulatory-care pharmaceutical services, a results-oriented performance-appraisal system, more support for clinical education programs, and a substantial increase in support for research. The strategic plan has allowed the department to constructively participate in two downsizing events within the hospital without major adverse effects on its own services and programs. Use of the strategic-planning process should be considered by other hospital pharmacy departments as a means of responding to the external and internal forces of change that currently affect most hospitals.
