Sociodemographic,health-related and lifestyle correlates of physical activity in adults with current asthma

Objective: Regular physical activity is associated with better asthma control; however, little is known of the determinants of physical activity in a population of adults with asthma. Thus, the purpose of this study was to identify important sociodemographic, health and lifestyle correlates of physical activity among adults with asthma. Methods: Data from adults with asthma aged 18–44 years (n = 2740) from the Canadian Community Health Survey (CCHS), 2011–2012 annual component were used for analysis. The main outcome was Daily Energy Expenditure (DEE). This variable was based on frequency and duration of leisure activities in the past 3 months. Self-reported sociodemographic (age, sex, total household income, highest education level, and ethnicity), health-related (body mass index (BMI), self-perceived health, mood disorder, anxiety disorder, and asthma symptoms/attacks, past year) and lifestyle (type of smoker, sedentary time, fruit and vegetable consumption) variables were assessed as correlates for DEE. Data were analysed using linear regressions. Results: In the final model, sociodemographic correlates accounted for 4.2% of the variation in DEE. Adding health correlates increased the R² to 12.1%. Finally, adding lifestyle correlates increased the R² to 17.6%. Conclusions: In adults with current asthma, the main correlates of physical activity are age, total household income, BMI, self-perceived health, anxiety disorder, sedentary time, and fruit and vegetable consumption. These data are important for informing education and exercise interventions for adults with asthma. Future research is needed to determine asthma-specific correlates of physical activity.     

Linguistic validation of stigmatisation degree,self-esteem and knowledge questionnaire among asthma patients using Rasch analysis

Background and Objective: The stigmatisation degree, self-esteem and knowledge either directly or indirectly influence the control and self-management of asthma. To date, there is no valid and reliable instrument that can assess these key issues collectively. The main aim of this study was to test the reliability and validity of the newly devised and translated “Stigmatisation Degree, Self-Esteem and Knowledge Questionnaire” among adult asthma patients using the Rasch measurement model. Methodology: This cross-sectional study recruited thirty adult asthma patients from two respiratory specialist clinics in Selangor, Malaysia. The newly devised self-administered questionnaire was adapted from relevant publications and translated into the Malay language using international standard translation guidelines. Content and face validation was done. The data were extracted and analysed for real item reliability and construct validation using the Rasch model. Results and Conclusion: The translated “Stigmatisation Degree, Self-Esteem and Knowledge Questionnaire” showed high real item reliability values of 0.90, 0.86 and 0.89 for stigmatisation degree, self-esteem, and knowledge of asthma, respectively. Furthermore, all values of point measure correlation (PTMEA Corr) analysis were within the acceptable specified range of the Rasch model. Infit/outfit mean square values and Z standard (ZSTD) values of each item verified the construct validity and suggested retaining all the items in the questionnaire. The reliability analyses and output tables of item measures for construct validation proved the translated Malaysian version of “Stigmatisation Degree, Self-Esteem and Knowledge Questionnaire” as a valid and highly reliable questionnaire.     

Persistent differences in asthma self-efficacy by race,ethnicity, and income in adults with asthma

Abstract

Objective: The objective of this population-based study was to determine if and to what extent there are differences in asthma self-efficacy by race/ethnicity and income, and whether health status, levels of acculturation, and health care factors may explain these differences. Methods: We conducted a secondary data analysis of asthma self-efficacy using the 2009 and 2011–2012 California Health Interview Survey, in adults with asthma (n?=?7874). In order to examine if and how the effect of race/ethnicity and income on asthma self-efficacy may have been altered by health status, acculturation, and health care factors, we used staged multivariable logistic regression models. We conducted mediation analyses to evaluate which of these factors might mediate disparities in self-efficacy by race/ethnicity and income. Results: 69.8% of adults reported having high asthma self-efficacy. Latinos (OR 0.66; 95% CI 0.51–0.86), African-Americans (OR 0.50; 95% CI 0.29–0.83), American Indian/Alaskan Natives (OR 0.55; 95% CI 0.31–0.98) and Asian/Pacific Islanders (OR 0.34; 95% CI 0.23–0.52) were less likely to report high self-efficacy compared to Whites. Individuals with income below the federal poverty level (OR 0.56; 95% CI 0.40–0.78) were less likely to report high self-efficacy compared to higher income individuals. The relationship between income and self-efficacy was no longer significant after further adjustment for health care factors; however, the differences in race and ethnicity persisted. Receiving an asthma management plan mediated the relationship in certain subgroups. Conclusions: Addressing modifiable health care factors may play an important role in reducing disparities in asthma self-efficacy.     

Association between quality of life in parents and components of asthma control in children

Objective: Describe the association between parents’ quality of life and the two components of asthma control in children: impairment and risk. Methods: Cross-sectional study with children between 4 and 14 years of age with active asthma recruited at primary care centers in Spain. Asthma control was assessed according to the Third National Asthma Expert Panel Report, classifying “impairment” in three levels (well-controlled asthma, partially controlled, and poorly controlled), and “risk” as high or low. The parents’ quality of life was evaluated using the specific Family Impact of Childhood Bronchial Asthma Questionnaire instrument (IFABI-R). The association between asthma control and the parents’ quality of life was analyzed using multivariate regression models adjusted for other social and family variables. Results: Data from 408 children were analyzed. The parents’ quality of life was affected in the partially controlled asthma group when compared with well-controlled asthma, as showed by an increase in IFABI-R scores in all dimensions: functional 17.2% (p?p?=?0.021), and socio-occupational 6.8% (p?=?0.056). The differences were higher in poorly controlled asthma compared with well-controlled asthma: functional 24.3% (p?=?0.001), emotional 18.9% (p?=?0.008), and socio-occupational 11.5% (p?=?0.036). The “risk” component was independently associated with the parents’ quality of life. Of all the elements used to assess the control, the only one independently associated with the parents’ quality of life was recurrent asthma crisis. Conclusions: In asthma control, both “impairment” and “risk” in children are gradually associated with the parents’ quality of life. The global assessment of the control surpasses the importance of each individual element used in this assessment.     

Use of health-related, quality-of-life metrics to predict mortality and hospitalizations in community-dwelling seniors

OBJECTIVES: To investigate whether health-related quality-of-life (HRQoL) scores in a primary care population can be used as a predictor of future hospital utilization and mortality. DESIGN: Prospective cohort study measuring Short Form 12 (SF-12) scores obtained using a mailed survey. SF-12 scores, age, and a comorbidity score were used to predict hospitalization and mortality rate using multivariable logistic regression and Cox proportional hazards during the ensuing 28-month period for elderly patients. SETTING: Intermountain Health Care, a large integrated-delivery network serving a population of more than 150,000 seniors. PARTICIPANTS: Participants were senior patients who had one or more chronic diseases, were community dwelling, and were initially treated in primary care clinics. MEASUREMENTS: SF-12 survey Version 1. RESULTS: Seven thousand seventy-six surveys were sent to eligible participants; 3,042 (43%) were returned. Of the returned surveys, 2,166 (71%) were complete and scoreable. For the respondent group, a multivariable analysis demonstrated that older age, male sex, higher comorbidity score, and lower mental and physical summary measures of SF-12 predicted higher mortality and hospitalization. On average, nonresponders were older and had higher comorbidity scores and mortality rates than responders. CONCLUSION: The SF-12 survey provided additional predictive ability for future hospitalizations and mortality. Such predictive ability might facilitate preemptive interventions that would change the course of disease in this segment of the population. However, nonresponder bias may limit the utility of mailed SF-12 surveys in certain populations.     

An examination of comorbid asthma and obesity: assessing differences in physical activity,sleep duration,health-related quality of life and parental distress

Objective: Compare youth with comorbid asthma and obesity to youth with obesity only to determine if differences exist in body mass index, dietary intake, levels of physical activity, sleep duration and health-related quality of life. Levels of parent distress were also compared. Methods: Participants included 248 children (n?=?175 in Obesity group; n?=?73 in Asthma?+?Obesity group) with a BMI?≥?85th percentile for age and gender, and their participating parent(s) or legal guardian(s). Measures of child height and weight were obtained by study personnel and Z-scores for child body mass index were calculated using age- and gender-specific norms. Child physical activity and sleep duration were measured via accelerometers. Dietary intake, health-related quality of life and parent distress were assessed via self-report. Results: The Asthma?+?Obesity group evidenced significantly higher body mass index scores, and had lower sleep duration. There was a non-statistically significant trend for lower levels of physical activity among children in the Asthma?+?Obesity group. Dietary intake, health-related quality of life and parent distress did not differ between groups. Conclusions: Youth with comorbid asthma and obesity are at increased risk for negative health and psychosocial difficulties compared to youth who are overweight or obese only. Professionals providing treatment for youth with asthma are encouraged to assess the implications of weight status on health behaviors and family psychosocial adjustment.     

Cross-sectional survey study to examine underuse of twice daily inhaled maintenance therapy among patients with asthma

Objective: Anecdotal evidence suggests that some patients with asthma intentionally use their twice-daily (BID) inhaled controller therapy once daily (QD), thus not achieving optimal dosing levels. This study identified the prevalence of and factors associated with intentional QD use of BID-indicated controllers among adult patients with asthma. Methods: This was a cross-sectional survey study of adults using inhaled controllers intended for BID dosing for treatment of asthma and/or COPD. Survey responses were linked to administrative claims data for the prior 12?months (baseline). Results of patients indicating both an asthma diagnosis and current intentional QD or BID use of controllers are presented. Results: Of 1401 patients with asthma, 30.9% reported intentional QD use of their controller and 69.1% reported BID use. Intentional QD use was mostly a function of patients’ lack of perceived need for BID treatment (44.1%) or physician orders to take their controller QD (34.0%). Patients reporting intentional QD use tended to be healthier (higher health status scores, and lower Charlson comorbidity scores, ambulatory and ER visits, and healthcare costs) with better asthma control (lower asthma-related ER and ambulatory visits and rescue medication use, and higher Asthma Control Test scores) compared with patients reporting BID use. Conclusions: Perceptions regarding health and the necessity of controller use to control or treat asthma were the main drivers of medication-taking behavior. Patients with less severe asthma were more likely to report once daily use of their inhaled controller, but still maintained asthma control.     

Improved quality-of-life of caregivers of children with asthma through guideline-based management

Objective: The quality of life (QOL) of caregivers of children with asthma may be related to children's responses to asthma management. Aim: To evaluate change in QOL over time of caregivers of children with asthma through guideline-based management. Design: This was a 3-year prospective cohort study of children with asthma referred to our pediatric asthma center. Families completed Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ), the Asthma Control Test? (ACT), and reported the number of days/month of albuterol use and wheezing at each clinic visit. Results: We enrolled 143 children, ages 7–17 years (mean = 10.6 ± 2.9), 56.6% male, 70.6% Caucasian. Patients were managed by the same MD (n = 65,45.5%) or APN (n = 78,54.5%) over time. The mean total PACQLQ significantly increased over the 3-year period (F = 67.418, p < .001). Total scores at the first visit were 4.8 ± 1.6, which improved to 6.1 ± 1 at the 3-month follow-up visit. This improvement was sustained at the 1, 2, and 3-year clinic visits. PACQLQ emotional function (F = 60.798, p < .001) and activity limitation (F = 41.517, p < .001) domains significantly improved as well. PACQLQ scores were significantly associated with improved ACT scores (r = .37 to .47, p < .05), fewer days/month of albuterol use (r = ?.25 to ?.36., p < .05), and wheezing (r = ?.28 to ?.33, p < .05). There were no significant differences in PACQLQ, or asthma clinical outcome measures between MD and APN providers. Conclusion: Use of National Asthma Education and Prevention Program (NAEPP) guidelines significantly improved QOL of caregivers of children with asthma and in asthma-related symptoms. Improvements over time were independent of type of providers.     

Irreversible airway obstruction in asthma: A risk factor for severe exacerbations in spite of proper treatment

Objectives: To evaluate whether irreversible airway obstruction (IAO) related to asthma is a risk factor for lack of symptoms control, poor quality of life and exacerbations. Methods: We evaluated consecutive outpatients with asthma in a one-year cohort study. We excluded subjects with smoke history > 9 pack-years. Definition of IAO was post bronchodilator FEV₁/CVF ratio below the lower limit of normality. Subjects received high dose of inhaled medications for asthma. We used logistic regression models, adjusted for the treatment offered during the study, to evaluate whether IAO related to asthma is a risk factor for symptoms control, quality of life, any emergency room visit, number of emergency room visits and hospital admission. Results: We enrolled 248 subjects in the study. IAO was not a risk factor for poor symptoms control [OR 1.354, 95 CI (0.632–2.899)] or worse asthma related quality of life [OR 0.705, 95 CI (0.413–1.204)]. Subjects with IAO had higher odds of any emergency room visit [OR 2.214, 95 CI (1.300–3.768)] and hospital admission [OR 8.530, 95 CI (1.517–47.978)] and lower odds to reduce emergency room visits in the course of the follow-up period [OR 0.452, 95 CI (0.265–0.769)]. IAO did not predict the number of emergency room visits [OR 1.53, 95 CI (0.71–3.30). Conclusion: IAO is not a risk factor for poor symptoms control or poor quality of life, in a setting of proper treatment. It is a risk factor for emergency room visit and hospital admission. Subjects with IAO have poor response to treatment.     

Comparison between a general and a disease-specific health-related quality-of-life questionnaire in patients after pancreatic surgery

Background/Purpose

The aim of this study was to compare the short-form (SF-) 36 as a general instrument and the gastrointestinal quality of life index (GIQLI) as a disease-specific instrument in patients after pancreatic surgery.

Methods

The questionnaires were sent to patients receiving pancreatic surgery over a time period of three years. Patients were compared with a normal population completing the SF-36 or reported normal-population values for the GIQLI. Agreement between the instruments was analyzed using Bland Altman plots.

Results

A total of 98 patients were included, most of them undergoing a Whipple procedure (86%). The most frequent complaints were meteorism, obstipation, stool urgency, and stress incontinence in 9% of the patients. Whereas in almost every domain of the SF-36 the HRQL was impaired in comparison to the normal population, the GIQLI showed differences in only the domain emotions. Neither the SF-36 nor the GIQLI was different between patients with early and advanced cancer stages. The SF-36 had no agreement with the GIQLI.

Conclusions

The results of HRQL studies depend on the instruments which were used. Whereas a general instrument may detect factors such as comorbidity more accurately, disease-specific instruments have the advantage of better clinical interpretability.     

Assessing the impact of a remote digital coaching engagement program on patient-reported outcomes in asthma

Background: Low adherence and poor outcomes provide opportunity for digital coaching to engage patients with uncontrolled asthma in their care to improve outcomes. Objective(s): To examine the impact of a remote digital coaching program on asthma control and patient experience. Methods: We recruited 51 adults with uncontrolled asthma, denoted by albuterol use of >2 times per week and/or exacerbations requiring corticosteroids, and applied a 12-week patient-centered remote digital coaching program using a combination of educational pamphlets, symptom trackers, best peak flow establishment, physical activity, and dietary counseling, as well as coaches who implemented emotional enforcement to motivate disease self-management through telephone, text, and email. Baseline and post-intervention measures were quality of life (QOL), spirometry, Asthma Control Test (ACT), Asthma Symptom Utility Index (ASUI), rescue albuterol use, and exacerbation history. Results: Among 51 patients recruited, 40 completed the study. Eight subjects required assistance reading medical materials. Significant improvements from baseline were observed for Patient-Reported Outcomes Measurement Information System mental status (p = 0.010), body weight, and outpatient exacerbation frequency (p = 0.028). The changes from baseline in ACT (p = 0.005) were statistically significant but did not achieve the pre-specified minimum clinically important difference (MCID), whereas for ASUI, the MCID and statistical significance were achieved. Spirometry and rescue albuterol use were no different. Conclusion: A patient-oriented, remote digital coaching program that utilized trained health coaches and digital materials led to statistically significant improvement in mental status, outpatient exacerbations, body weight, and ASUI. Digital coaching programs may improve some outcomes in adults with uncontrolled asthma.     

Sex-differences in quality of life and asthma control in Swedish asthma patients

Abstract

Background: To study sex-related differences in quality of life, asthma control and asthma management in different age groups. Methods: A cross-sectional survey and patient record study in primary and secondary care. A total of 1226 patients in primary and 499 in secondary care, ages 18–75 and randomly selected, with a response rate of 71%. Patients were classified into four groups, 18–34, 35–49, 50–64 and 65–75 years. Results: Younger women (18–49 years) had a lower total MiniAQLQ score than men in the same age group (5.41 vs. 5.80, p?<?0.001), while no significant difference was found between older women and men (50–75 years) (5.08 vs. 5.16, p?=?0.42). The sex differences in the younger group remained significant after adjusting for medication, educational level, smoking, body mass index, allergy and depression (p?=?0.008). The odds ratios for younger women to have night-awakenings was 1.7 (95%CI 1.07–2.57), for asthma exacerbations 1.9 (95%CI 1.21–2.98) and for not achieving asthma control 1.5 (95%CI 1.00–2.13) when adjusting for smoking, educational level and body mass index. No differences in asthma control were found when comparing older women with men of similar ages. Conclusions: Younger women had lower quality of life and less often asthma control than men in the same age range, while no corresponding sex differences were found between older women and men of similar ages. Female sex hormones could be an important factor affecting these outcomes.     

A study to assess inhaler technique and its potential impact on asthma control in patients attending an asthma clinic

Objectives: The aim of this study was to evaluate inhaler technique and symptom control in patients with poorly controlled asthma at baseline and at follow-up in a dedicated asthma clinic in a tertiary hospital. We also investigated the impact of asthma on these patients’ quality of life. Methods: Patients referred to a newly established asthma clinic in Cork University Hospital were prospectively recruited over a 6-month period. Their inhaler technique was assessed by a pulmonary nurse specialist using a validated scoring system. They received instruction on inhaler usage when scores were suboptimal. Patients completed a validated asthma control questionnaire (ACQ) and asthma quality of life questionnaire (AQLQ). At follow-up 3–4 months later, the inhaler technique was reassessed and the ACQ questionnaire repeated. Results: Forty-six patients were recruited (female?=?74%), and 40/46 were followed up. Mean [SD] FEV1 % predicted at baseline?=?76.5% [21.5]. About 63% of the patients were classified as incorrectly using their inhaler at their initial assessment. This decreased to 20% at follow-up, indicating an overall significant improvement in inhaler usage post-training (p?=?0.003). ACQ scores improved significantly from median [interquartile range] 2.70 [1.66] to 2.00 [1.90] (p?=?0.002). Baseline measurement indicated that patients’ quality of life was moderately affected by asthma, with a median AQLQ score of 4.75 [1.97]. Conclusion: This study demonstrates the importance of educating and formally assessing inhaler technique in patients with asthma as a part of their ongoing clinical review.     

Effects of depressive symptoms on health-related quality of life in asthma patients

OBJECTIVE: To assess the effects of depressive symptoms on asthma patients’ reports of functional status and health-related quality of life. DESIGN: Cross-sectional study. SETTING: Primary care internal medicine practice at a tertiary care center in New York City. PATIENTS: We studied 230 outpatients between the ages of 18 and 62 years with moderate asthma. MEASUREMENTS AND MAIN RESULTS: Patients were interviewed in person in English or Spanish with two health-related quality-of-life measures, the disease-specific Asthma Quality of Life Questionnaire (AQLQ) (possible score range, 1 to 7; higher scores reflect better function) and the generic Medical Outcomes Study SF-36 (general population mean is 50 for both the Physical Component Summary [PCS] score and Mental Component Summary [MCS] score). Patients also completed a screen for depressive symptoms, the Geriatric Depression Scale (GDS), and a global question regarding current disease activity. Stepwise multivariate analyses were conducted with the AQLQ and SF-36 scores as the dependent variables and depressive symptoms, comorbidity, asthma, and demographic characteristics as independent variables. The mean age of patients was 41 ± SD 11 years and 83% were women. The mean GDS score was 11 ± SD 8 (possible range, 0 to 30; higher scores reflect more depressive symptoms), and a large percentage of patients, 45%, scored above the threshold considered positive for depression screening. Compared with patients with a negative screen for depressive symptoms, patients with a positive screen had worse composite AQLQ scores (3.9±SD 1.3 vs 2.8±SD 0.8, P<.0001) and worse PCS scores (40±SD 11 vs 34±SD 8, P<.0001) and worse MCS scores (48±SD 11 vs 32±SD 10, P<.0001) scores. In stepwise analyses, current asthma activity and GDS scores had the greatest effects on patient-reported health-related quality of life, accounting for 36% and 11% of the variance, respectively, for the composite AQLQ, and 11% and 38% of the variance, respectively, for the MCS in multivariate analyses. CONCLUSIONS: Nearly half of asthma patients in this study had a positive screen for depressive symptoms. Asthma patients with more depressive symptoms reported worse health-related quality of life than asthma patients with similar disease activity but fewer depressive symptoms. Given the new emphasis on functional status and health-related quality of life measured by disease-specific and general health scales, we conclude that psychological status indicators should also be considered when patient-derived measures are used to assess outcomes in asthma. This project was supported by a Robert Wood Johnson Foundation Generalist Physician Faculty Scholar’s Award to Dr. Mancuso.     

Evaluating the implementation of a multicomponent asthma education program for Head Start staff

Objective: Asthma disproportionately affects minority groups, low income populations, and young children under 5. Head Start (HS) programs predominantly serve this high-risk population, yet staff are not trained on asthma management. The objective of this study was to assess a 5-year, multicomponent HS staff asthma education program in Baltimore City HS programs. Methods: All HS programs were offered annual staff asthma education by a medical research team that included didactic lectures and hands-on training. Attendees received continuing education credits. HS staff were anonymously surveyed on asthma knowledge and skills and asthma medication management practices in Year 1 (preimplementation) and Year 5. Results: There was an estimated response rate of 94% for Year 1 and 82% for Year 5. Compared to staff in Year 1, Year 5 staff were significantly more likely to report they had very good knowledge and skills related to asthma [odds ratio (OR) 1.63; p < 0.05] and were engaged in asthma care activities (OR 2.02; p < 0.05). Self-reported presence of asthma action plans for all children with asthma was 82% at Year 1 and increased to 89% in Year 5 (p = 0.064). Conclusions: Year 5 HS staff reported higher self-assessed knowledge and skills, self-reports of asthma medication management practices, and self-reports of asthma activities compared to Year 1 staff. HS serves high-risk children with asthma, and a multicomponent program can adequately prepare staff to manage asthma in the child care setting. Our results indicate the feasibility of providing efficacious health skill education into child care provider training to reduce asthma knowledge gaps.     

Examining health literacy among urban African-American adolescents with asthma

Objective: This exploratory study assessed health literacy among urban African-American high school students to improve understanding of the association between adolescent health literacy and asthma. Methods: We conducted a secondary data analysis of the control group (n = 181) of the Puff City randomized controlled trial (2006–2010), a web-based intervention to promote asthma management among students, grades 9 through 12. A validated self-report 3-item health literacy screening instrument was completed at final online follow-up survey. Logistic regression was used to explore the association between health literacy, demographic characteristics, quality of life, asthma management, and health care utilization. Results: Multivariate analysis revealed that an overall inadequate health literacy score was associated with students who were more likely to be younger (OR 0.61; 95% CI 0.44–0.84), not on Medicaid (OR 0.36; 95% CI 0.17–0.76), have at least one hospitalization (OR 1.29; 95% CI 1.07–1.56); and a lower overall quality of life (OR 0.75; 95% CI 0.59–0.95). Those lacking confidence in filling out medical forms, needing help reading hospital materials, and having difficulty understanding written information were more likely to not have a rescue inhaler (OR 0.49; 95% CI 0.25–0.94), have one or more emergency visits (OR 1.21 95% CI 1.02–1.43), and one or more hospitalizations (OR 1.19; 95% CI 1.01–1.41), respectively. Conclusions: The findings indicate a significant association between inadequate health literary and suboptimal asthma management. It is important to advance understanding of adolescent health literacy, especially those at-risk, as they assume asthma self-management tasks and move toward independent adult self-care.     

Medication identification in pediatric asthma (MED ID): The reliability and validity of a novel screening tool

Objectives: To evaluate the reliability and validity of medication identification (MED ID), a novel survey assessing caregiver-perceived ability to identify inhaled asthma medications. Methods: We analyzed baseline data from the School-Based Asthma Care for Teens trial in Rochester, NY. Caregivers of adolescents with persistent asthma named the inhaled medications used by their child and identified medications on a pictorial chart. Accurate identification was defined as completed matches between listed names and selected images. Caregivers answered the MED ID survey of four scaled questions on perceived ability to identify inhaled medications. We determined internal consistency reliability using Cronbach's alpha; examined concurrent validity by comparing MED ID sum scores with accurate identification using bivariate and multivariate analyses; and assessed the diagnostic utility of MED ID through receiver operating characteristic analysis. Results: 126 caregivers (76% of enrolled) reported >1 inhaled medication; 52% of caregivers accurately identified medications. Two MED ID questions were removed during analysis. The two remaining questions had a score range of 2–10 points; higher scores indicate greater caregiver-perceived ability to identify medications. The Cronbach's alpha was 0.603. Accurate identification of medications was associated with a higher mean MED ID score (8.6 vs 7.6, p = 0.01). Accuracy was most strongly associated with MED ID scores ≥8 points (88% vs 60%, p < 0.001, Phi 0.32); findings were consistent in regression analysis. The greatest area under the curve was seen with MED ID scores ≥8 points (0.638). Conclusions: The two-item MED ID survey is a reliable and valid way to assess caregiver's ability to identify inhaled asthma medications.
