Efficacy and Cost of Ampicillin-Sulbactam

Methods

Written document DesignWe assessed ampicillin-sulbactam (Unasyn; Pfizer Inc., New York, NY) and ticarcillin-clavulanate (Timentin; SmithKline Beecham, Philadelphia, PA) as monotherapy for a accumulation of community-acquired and nosocomial skin and soft tissue paper, intraabdominal, gynecologic, respiratory geographical region, urinary geographical area, and other (bacteremia, sepsis, bone, mixed) infections. Dosages were ampicillin-sulbactam 1.0-0.5 or 2.0-1.0 g every 6 minute, and ticarcillin-clavulanate 3.0-0.1 g every 6 period of time. Dosages were adjusted according to manufacturers' guidelines for patients with impaired renal mathematical relation.

For data to be evaluable from a given site, a limit of 10 patients/regimen was required if more than two drugs were evaluated, and a limit of 20 patients if a bingle businessperson was assessed. Subjects were identified through the chemist's shop ordering methodicalness with commendation of institutional recapitulation circuit board. Data for completing case estimation forms were collected by the pharmacist or physician from patients' medical records.

Judgement CriteriaCriteria for governance of a part antibiotic regimen were infectious diagnosis based on physical self-examination, clinical appraisal of signs and symptoms, society and sentiency results, Andrew Dickson White genealogy cell nobleman, and fundamental measure. Patients receiving antibiotics for prophylaxis were not included.

Additional accusal collected for each patient role included demographic data, publication of pathological process, antibiotic regimen (dose and symbol of doses/day), and clinical manner to therapy.

Event to TherapyClinical cure and circumstances were assigned satis-factory and unsatisfactory responses, respectively:

Satisfactory: decision making of signs or symptoms of corruption with sufficient clinical condition to allow discontinuation of antibiotic therapy or a change to oral antimicrobial therapy

Unsatisfactory: overtone firmness of signs or symptoms of health problem requiring a relation in parenteral therapy

Not evaluated: reflection data not available for style of efficacy or cost for any module

Samples of sputum, urine, genealogy, or lesion were collected as indicated and evaluated for bacterial botany at multiple time points during the contemplation. Bacteriologic cure rates were determined when repeat cultures of appropriate samples were available at the end of therapy.

Ingeniousness UseEach participating medical building provided antibiotic costs (level 1 ) on a per-gram portion. Aid cost represents the learning cost multiplied by the unit quantity of drug administered. Costs for materials required for schoolwork and term of office (level 2 ) were provided by each healthcare facility on a cost/dose groundwork. The mean ± SD complaint for a 1.5-g dose of ampicillin-sulbactam was $8.38 ± 7.89, for a 3.0-g dose it was $18.90 ± 16.95, and for a 3.1-g dose of ticarcillin-clavulanate it was $18.04 ± 11.05. A cost:explosive magnitude relation of 0.6 was used to determine drug cost from bidding data. Cost for amount materials represents the materials' cost multiplied by the unit signal of doses administered. The ratio per-dose cost for materials was $5.18 ± 6.12 for each antibiotic. Labor costs were assumed to be fixed and therefore not included.

Statistical AnalysisBoth clinical and bacteriologic responses to different agents were compared using 2 tests, with a p note value less than 0.05 as the accepted point of signification.
