Spacer microbial contamination and asthma outcomes: case series.

OBJECTIVE: The primary method of drug delivery to treat asthma is through pressurized metered dose inhalers (pMDI). Asthma guidelines recommend that providers prescribe a spacer for all patients using pMDI. The objective of this study was to examine whether microbial contamination of spacer devices is associated with poor asthma outcomes. METHODS: This was a cross-sectional, single-center case series of seven pediatric patients with persistent asthma who had previously been prescribed a spacer. Spacers were swabbed with sterile cotton and samples assessed for bacterial/fungal growth. Parents completed a questionnaire including Asthma Control Test (ACT) and asthma control was assessed by an Allergist/Immunologist physician. RESULTS: Two (n = 2) children's parent-completed ACT score indicated poorly controlled asthma and three (n = 3) patients were noted to be poorly controlled by the physician. All but one caregiver reported cleaning the spacer with most reporting (n = 5) that they cleaned their child's spacer monthly and one (n = 1) reporting cleaning it every two weeks. One spacer had detected Candida albicans. There was not a statistically significant association between ACT score and microbial growth (p > 0.05). CONCLUSION: Most spacers in a pediatric sample were not contaminated, despite lack of consistent cleaning, as recommended by spacer manufacturers. Providers and pharmacists should discuss proper cleaning of spacers with caregivers of pediatric patients.

Using Resident and Faculty Focus Groups to Obtain Stakeholder Input during the ACGME Self-study.

INTRODUCTION: The Accreditation Council for Graduate Medical Education describes steps to guide programs regarding self-study. The process relies heavily on obtaining stakeholder input to validate findings. Focus groups have been noted to provide input and data not elicited using other methods. Our objective was to show the value of focus groups in obtaining a clear picture of stakeholder priorities as they relate to program aims, opportunities, threats, areas for improvement, and sustainability of improvements. METHODS: We conducted a series of focus groups in 2017-2018 at a pediatric residency program with residents and core faculty members. The first session for each group elicited input regarding program aims, opportunities, and threats. The second session focused on evaluating program progress over the past 10 years and identifying strengths and needed areas for improvement. We documented responses obtained during the focus groups and used inductive content analysis methods to identify major themes. We repeated the focus groups every 6 months. RESULTS: We identified 8 program aims and pinpointed opportunities and threats. Areas for improvement were selected and then presented back to the stakeholders who confirmed their appropriateness. Repetition of the focus groups every 6 months facilitated ongoing measurement of progress and promoted the development of multiple plan, do, study, act cycles for areas of improvement. CONCLUSIONS: Focus groups are an effective way to initiate the self-study process, examine the program aims, opportunities, and threats, and formulate a detailed improvement plan. They are also useful as part of continual evaluation during a dynamic change process.

Children with asthma and their caregivers help improve written asthma action plans: A pilot mixed-method study.

OBJECTIVE: The objectives of this study were to (a) qualitatively examine caregiver and child feedback about a gold standard written asthma action plan (WAAP), and (b) determine whether having an asthma action plan was associated with child and caregiver self-efficacy in managing an exacerbation. METHODS: This was a cross-sectional analysis of structured interviews with 22 children with persistent asthma that collected feedback about the WAAP as well as self-efficacy. An analysis of interviews used the constant comparative method to identify themes of child and caregiver statements. Caregivers completed a questionnaire that measured asthma management self-efficacy, barriers to managing asthma, and belief in the treatment efficacy using validated scales. RESULTS: Approximately 36% of the caregivers reported having a WAAP for their child from their child's pediatrician. Most caregivers stated that having pictures would improve the WAAP, while most children stated that the layout needed to be improved by adding more space between the sections. Caregivers who reported knowing what the asthma action plan was had greater self-efficacy than caregivers who did not (z = -1.99, p = 0.047). CONCLUSIONS: Re-designing the current WAAP layout and including pictures of inhalers may promote patient understanding. Future research needs to examine if a re-designed WAAP improves asthma management of children with asthma and their caregivers.

Improving Resident Knowledge of Spacers.

Studies show the delivery of inhaled medications is maximized when a metered-dose inhaler (MDI) with a spacer is utilized. Our residents expressed concern with their knowledge of MDIs and spacers. This study was designed to address those concerns. Residents were given a 12-question pre-intervention, self-assessment questionnaire that explored their overall knowledge and comfort in utilizing MDI with spacers. Participants then received educational intervention via multimedia videos and a demonstration of proper use of MDI with spacer. Participants were given the same questionnaire immediately following the education and again 3 months later. Improvement was significant (P < .05) for each element studied as derived from the 12 questions. Improvement remained significant when these variables were assessed in the 3-month follow-up. In this study, we successfully improved the ability of our residents to deliver quality care by improving their knowledge and confidence in utilizing MDIs with spacers.

Inhaler Technique in Children With Asthma: A Systematic Review.

BACKGROUND: Pediatric asthma is an important public health problem worldwide. The primary methods of medication delivery are inhalation devices. OBJECTIVES: This systematic review examined: 1) what is the prevalence of correct inhaler technique among children with asthma, 2) are educational interventions associated with improved rates of correct inhalation technique, and 3) is improved inhaler technique associated with improved asthma outcomes? DATA SOURCES: We included experimental and observational studies through searches of PubMed, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CINAHL Complete, and clinicaltrials.gov. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: Studies were eligible for this review if at least 1 outcome measure of the study included and reported results of child/adolescent inhaler technique. STUDY APPRAISAL AND SYNTHESIS METHODS: The following information was extracted from each included study: study design (experimental vs observational), and outcomes data. The Downs and Black checklist was used to appraise study quality. RESULTS: Twenty-eight studies were eligible for inclusion. We found that inhaler technique is generally very poor among children, but is better when children use their metered-dose inhalers (MDIs) with spacers. Technique in using turbuhalers and diskus inhalers is better than in MDI, but still poor. Counseling children on correct inhaler technique was associated with improved technique among children in multiple studies. LIMITATIONS: We examined articles published in English. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Inhaler technique in children is generally poor. Physicians and other members of the health care team should instruct children and their caregivers on the proper use of their inhalation devices at every opportunity and correct mistakes when made to ensure effective medication delivery.

Anaphylaxis to gadolinium radiocontrast: a case report and review of the literature.

Gadolinium was first introduced in 1988 for use in magnetic resonance imaging. The safety of gadolinium chelates is well established with lower frequency of adverse reactions than non-ionic iodinated contrast media; however, serious adverse reactions can occur. We report a rare case of anaphylaxis after intravenous administration of gadopentetate dimeglumine (Magnevist), used for magnetic resonance imaging.
