Rangel QI : Antibiotic Stewardship in the Ambulatory Setting COS – May 15, 2013

Background Information Antibiotic prescribing in the ambulatory setting occurs >1 in 5 visits In study of pediatric office visits, antibiotics prescribed: 44% of visits for the common cold 75% of visits for bronchitis Estimate at least 40-50% of inappropriate antibiotic use While national antibiotic prescribing rates have decreased, more broad spectrum antibiotics are prescribed Inappropriate antibiotic use contributes to antibiotic resistance, side effects, and increased cost Pediatrics. 2012; 130: JAMA 2002; 287(23):

Background Information 3-24 months months 48-<72 months

Background Information

Questions How well do we adhere to Clinical practice guidelines for promoting appropriate antimicrobial use? How can we improve our practice? How can we increase the Rangel Community’s understanding of viral/bacterial infections and the clinically accepted guidelines for therapy? Focusing on common pediatric respiratory illnesses: Upper Respiratory Infection (URI) Acute Otitis Media (AOM) Streptococcal pharyngitis

AIM Statement AOM 1a) for pt’s 3-17yo with uncertain diagnosis or non-severe illness, increase our observation rates from 60% to 80% 1b) for pt’s 3-17yo with certain diagnosis and severe illness, increase our prescription of appropriate antibiotic from 73% to 90% Streptococcal pharyngitis 2) Improve the correct prescription (antibiotic, dose, duration) from 55% to 75% Viral URIs 3) For patients who present for sick visits and leave without antibiotic prescription, decrease the number who feel antibiotics are necessary from 85% to 65%

Provider cycles/interventions

Pre-intervention provider survey Survey Monkey survey of providers assessing knowledge, perceptions and practice of AOM diagnosis & management For children < 2 years of age with suspected AOM, how often do you prescribe antibiotics at time of diagnosis? 67% providers respond that they would always prescribe abx For children > 2 years of age with suspected AOM, how often do you prescribe antibiotics at the time of diagnosis? 17% providers responded that they would always prescribe abx

Didactics Powerpoint presentation to all providers to review the clinical guidelines for both AOM and Strep pharyngitis

Clinic materials Created handout materials & posters that highlighted the clinical guidelines and listed antibiotic options with dose and timing

2004 AAP/AAFP Clinical Practice Guideline: Diagnosis of Acute Otitis Media 3 major criteria for diagnosis of AOM: acute onset of symptoms signs of middle ear effusion limited or absent mobility bulging of TM air-fluid level otorrhea signs and symptoms of middle ear inflammation distinct erythema of TM distinct otalgia Pediatrics 2004; 113(5):

Patient cycles/interventions

Pre-intervention Patient Questionnaire: Paper/pen survey of random group of parents presenting for visits during a given block 85% of patients believed that antibiotics are appropriate for one of the following: ANY FEVER, ANY INFECTION, or ONLY VIRAL INFECTIONS. 45% of parents treat their children at home when sick 45% of parents take their children to the ED when sick Parents opt for the ED principally based on severity of illness, but also because they feel they are more likely to be seen by a doctor (rather than an allied health professional) and for convenience. 15% of parents call the clinic or walk-in when their child is sick, with 1/3 of these patients opting occasionally to take their children to the ED instead

Patient Interventions For patients discharged with viral diagnoses, providers were instructed to supply a viral prescription with written recommendations for care at home.

Patient Interventions Providers instructed to have patients read back the most important instructions in the viral prescription to maximize retention and ensure understanding In a study of critical laboratory values relayed by telephone to medical providers, physicians had an error rate of 5%, caught and corrected by a program of mandatory read back to laboratory technicians. Am J Clin Pathol 2004; 121:

Post-intervention Patient Questionnaire AIM Goal 3: For patients who present for sick visits and leave without antibiotic prescription, decrease the number who feel antibiotics are necessary from 85% to 65%

Sustainability within our ACN clinics Include lecture(s) on diagnosis of, and antibiotic prescription for, common outpatient presentations: AOM, Strep pharyngitis, CAP, bacterial sinusitis. Handout materials above provider offices and RN/MA stations. Acronym expander for AOM and Pharyngitis guidelines and other common outpatient walk-in visits. Use of viral prescriptions with read back method. Ensure availability of pneumatic otoscopy to increase accuracy of AOM diagnosis.
