RESUMEN
BACKGROUND: Suspected penicillin allergy (Pen-A) is often not verified by diagnostic testing. In third line penicillin allergy labels were associated with prescription of broad spectrum antibiotics, hospital stay duration and readmission. OBJECTIVE: Assess the impact of Pen-A labels on antibiotic and health care use in primary care. METHODS: A retrospective cohort study was conducted in primary care in the Utrecht area, the Netherlands. All patients registered with a penicillin allergy on 31 December 2013 were selected from the General Practitioner Network database. Each patient with a Pen-A label was matched for age, gender, follow-up period with three patients without Pen-A label. Risk (OR) of receiving a reserve and second choice antibiotic, number and type of antibiotics prescribed during follow-up and number of GP contacts were compared between the two cohorts. RESULTS: Of 196,440 patients, 1254 patients (0.6%) with a Pen-A label were identified and matched with 3756 patients without Pen-A label. Pen-A labels resulted in higher risk of receiving ≥1 antibiotic prescription per year (OR 2.56, 95% CI 2.05-3.20), ≥1 s choice antibiotic prescription per year (OR 2.21 95% CI 1.11-4.40), and ≥4 GP contacts per year (OR 1.71 95% CI 1.46-2.00). The chance of receiving tetracyclins (OR 2.24, 95% CI 1.29-3.89), macrolides/lincosamides/streptogamins (OR 8.69, 95% CI 4.26-17.73) and quinolones (OR 2.59, 95% CI 1.22-5.48) was higher in Pen-A patients. CONCLUSIONS: In primary health care Pen-A labels are associated with increased antibiotic use, including second choice antibiotics, and more health care use.
RESUMEN
OBJECTIVE: To evaluate the effectiveness of type 1 tympanoplasty with one-piece composite cartilage-perichondrium (CCP) grafts compared to temporalis fascia (TF) grafts for tympanic membrane (TM) closure and hearing improvement in adult patients with a subtotal TM perforation and chronic otitis media (COM). DATA SOURCES: PubMed, Embase, Cochrane Library. REVIEW METHODS: A systematic search was conducted. Relevance and validity of selected articles were assessed. Studies that scored moderate or high on relevance were included, and relevant data for both outcomes were extracted. For the outcome of TM closure, absolute risk differences (RD), relative risks, and number needed to treat with their respective 95% confidence intervals were calculated when possible. RESULTS: We retrieved 3,783 unique studies. Ten studies satisfied the eligibility criteria. Four studies of moderate validity showed RD ranging from 0.08 to 0.13 in favor of the CCP graft compared to the TF graft for TM closure 1 year or more postoperatively, but this was not statistically significant. Five studies of moderate to high validity showed no clinically relevant difference in hearing improvement between both intervention groups at a minimum follow-up of 3 months. The relative air-bone gap closure ranged from 5.7 to 11.5 dB in the TF group and from 8.9 to 12.7 dB in the CCP group. CONCLUSIONS: There is no evidence of superiority of one-piece CCP grafting over TF grafting in type 1 tympanoplasty regarding complete closure of a subtotal perforated TM 1 year or more postoperatively or hearing improvement at a minimum of 3 months follow-up.
