Evaluation of the inhalation technique in asthmatic children visiting a specialised outpatient clinic

Background and objective: Asthma is one of the most frequent chronic diseases affecting children and adolescents. Good compliance is indispensable for effective treatment since a suboptimal use of inhalation devices can result in decreased therapeutic efficacy and increased morbidity. The objective of this work was to evaluate the inhalation technique of paediatric patients visiting a specialized consultation clinic of a university hospital. Design: Observational prospective study during a 3-month period. Setting Specialized consultation clinic of a university hospital. Main outcome measures: This study involved 40 outpatient infants, children and adolescents visiting alone or with their parent(s). Patients' data (age, sex, weight, diagnostic, reason for consulting, previous consultations) and their medicines were compiled using an ad hoc form. Filmed sequences of the inhalation procedure used by each child were reviewed independently by members of an interdisciplinary team consisting in a physician, a pharmacist, a nurse and a physiotherapist. A score of 1 was assigned to each correct step in the procedure, and a score of 0 to an incorrect step. A perfect procedure implied 12 correct steps. Results: Thirty patients were treated with a metered-dose inhaler and an inhalation chamber (Babyhaler or AeroChamber Plus); ten other patients were treated with a dry powder inhaler (Diskus or Turbuhaler). The agreement between the members of the interdisciplinary team was considered satisfactory. Nine patients (22.5%) reached an average score lower than 7, 18 patients (45%) a score between 7 and 10 and 13 (32.5%) a score equal to or better than 10. No patient reached the maximum score of 12. Users of the metered-dose inhalers (average score = 9.2) showed a better technique than users of the dry powder inhalers (average score = 7.4). Disappointingly, the score was not improved during a second consultation or following regular consultations. Conclusions: Video recording is a simple method to evaluate the degree of mastery of an inhalation procedure in paediatric patients. The method allows a convenient and efficient identification of suboptimal procedure steps by the hospital staff, and opens the way to patient-specific teaching. In two-thirds of juvenile patients, their inhalation technique was suboptimal despite initial training. This study shows conclusively that the inhalation technique in paediatric patients must be monitored during each examination, and teaching measures taken to improve it when necessary

Inhalation technique practical skills and knowledge among physicians and nurses in two pediatric emergency settings

Introduction: Correct technique with a pressurized metered-dose inhaler (pMDI) equipped with a valved holding chamber (VHC) or spacer provides an important advantage for adequate control of asthma and virus-induced wheezing in young children. The aim of this study was to assess the ability and knowledge of physicians and nurses to use a pMDI with a masked VHC in two pediatric emergency units. Methods: Study design: Two-center observational study. Inhaler use technique was assessed in 50 physicians and 50 nurses using a child mannequin and a validated videotaped nine-step scoring method. The participants' knowledge was evaluated by a questionnaire. Results: The inhalation technique was perfectly mastered by 49% of the study participants and almost perfectly mastered by another 34% (mean score 8.3 ± 0.7; range 5-9). Nurses were more likely than doctors to demonstrate the technique perfectly (66% vs. 32%, p < 0.05). The two most common errors were forgetting to shake the pMDI between two consecutive puffs (38% of the participants) and putting the patient in an incorrect position (11%). About half of the participants reported that they checked each patient's inhalation technique at every opportunity and knew how to clean the VHC. A large majority did not employ a reliable method to determine the amount of medication remaining in pMDIs without a counter. Conclusion: Healthcare professionals' practical skills and knowledge on inhalation therapy were not completely mastered and could be improved with a mandatory training program

When fever, paracetamol? Theory and practice in a paediatric outpatient clinic

OBJECTIVE: To determine how medical and nursing staff treat feverish children and compare the findings with their theoretical knowledge, evaluating how they might contribute to fever phobia in parents.Setting: Paediatric Emergency Department. METHOD: In the first step, we analysed prospectively the files of all children having consulted the Paediatric Emergency Department with a history of fever or of body temperature above 38 degrees C during a 2-week period. The second step consisted of evaluating knowledge and perception of fever of doctors and nurses using a questionnaire. MAIN OUTCOME MEASURES: Prospective study: final diagnosis (viral, non- invasive bacterial disorders, invasive bacterial disorders), site of measurement and average temperature. Evaluation of theoretical knowledge: definition of fever, site of measurement, evaluation of the child's clinical state, antipyretic drug choice. RESULTS: A total of 114 children under 5 years of age were enrolled and 24 caregivers (12 doctors, 12 nurses, 90 of the staff) responded to the questionnaire. The results showed good consistency in theoretical knowledge, but an excessive fear about cerebral damage was also shown by doctors. This belief likely contributes to the transmission of fever phobia to parents. In contrast, analysis of children management showed that fever was often under-treated, especially by nurses and even more so by parents. Paracetamol remained the first-line antipyretic drug yet was often administered in insufficient doses. Non-steroidal anti-inflammatory drugs were seldom used, except by parents (16 of all the children). Contrary to literature, the favourite route of administration was the rectal one. Physical methods like sponging were largely used by nurses, despite the uncertainties in their real effectiveness and their known side-effects. CONCLUSION: Our study showed that the management of feverish children was globally correct in the Paediatric Emergency Department, but several improvement measures have been taken (e.g. tables of normal and abnormal ranges of temperature, recommended temperature measurement techniques, dosage regimen of antipyretic drugs, guidelines to parents), justifying the implementation of a pharmaceutical follow-up
