Effects of safety warnings on prescription rates of cough and cold medicines in children below 2 years of age.

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT: • Cough and cold medicines are frequently used in children to treat upper respiratory tract infections without solid proof of benefits. • Safety issues have been raised about the use of these drugs in young children. • In 2007 international warnings were issued advising against use of these drugs in young children. WHAT THIS STUDY ADDS: • Cough and cold medicines prescribing by primary care physicians has not really been influenced by international warnings in the Netherlands, where no additional national warnings were made and only partially in Italy. • A concerted action should be taken in Europe to advise strongly against the OTC use and prescription of cough and cold medicines in young children. AIM: The aim of the study was to assess the influence of national and international warnings on the prescription rates of cough and cold medicines (CCMs) in the youngest children (<2 years) in the Netherlands and Italy. METHODS: Analysis of outpatient electronic medical records of children <2 years in Italy and the Netherlands was carried out. Age and country specific prescription prevalence rates were calculated for the period 2005-08. Comparisons of prescription rates in 2005 (pre) and 2008 (post) warnings were done by means of a chi-square test. RESULTS: The cohort consisted of 99,176 children <2 years of age. After international warnings, overall prescription rates for CCMs decreased slightly from 83 to 77/1000 person years (P= 0.05) in Italy and increased in the Netherlands from 74 to 92/1000 children per year. Despite the international warnings, prescription rates for nasal sympathomimetics and opium alkaloids increased in the Netherlands (P < 0.01). In Italy a significant decrease in the prescription rates of opium alkaloids and other cough suppressants (P < 0.01) was observed, and also a significant reduction in use of combinations of nasal sympathomimetics. CONCLUSION: Despite the international safety warnings and negative benefit-risk profiles, prescription rates of cough and cold medicines remain substantial and were hardly affected by the warnings, especially in the Netherlands where no warning was issued. The hazards of use of these medicines in young children should be explicitly stipulated by the European Medicines Agency and all national agencies, in order to increase awareness amongst physicians and caretakers and reduce heterogeneity across the EU.

Patients' perceived burden of cystoscopic and urinary surveillance of bladder cancer: a randomized comparison.

OBJECTIVE: To compare, in patients with non-muscle-invasive low-grade (pTa/pT1, G1/G2) urothelial cell carcinoma of the urinary bladder, the perceived burden of flexible cystoscopy or surveillance by microsatellite analysis (MA) in voided urine, as such patients are normally recommended to adhere to regular cysto-urethroscopic surveillance (CUS). PATIENTS AND METHODS: In all, 220 participants of a randomized trial comparing CUS and surveillance by MA were asked to complete questionnaires 1 week after cystoscopy or urine sample collection. We assessed the discomfort and pain reported during CUS, experiences with MA, and physical symptoms, medical consumption and general functioning in the week after CUS/urine sampling. RESULTS: We analysed data from 732 questionnaires (197 patients) completed after CUS and 184 (67 patients) after collecting urine. The introduction of the cystoscope was reported to cause discomfort in 39% and pain in 35% of the responses to the questionnaires; the waiting time for the results of MA was reported as burdensome in 19%. Painful micturition was significantly more frequent in the week after CUS than after MA (30% and 12%, respectively). The frequency of fever (1% and 2%) and haematuria (7% and 6%) was similar in both groups. Older patients reported significantly less pain and discomfort from cystoscopy, and this was not related to having more previous cystoscopies. CONCLUSION: CUS caused pain and discomfort in about a third of patients. The burden of MA appeared fully attributable to the waiting time for the test result. The present results are a further motivation in the search for less invasive surveillance tests.
