Validity of a portable spirometer in the communities of China.

ABSTRACT:

Background

The lack of simple and affordable spirometry has led to the missed and delayed diagnoses of chronic respiratory diseases in communities. The PUS201P is a portable spirometry developed to solve this problem.

Objective

We aimed to verify the consistency of the PUS201P spirometer with conventional Jaeger spirometer.

Methods

In this cross-sectional study, we randomly recruited 202 subjects aged > 40 years. Testing with the portable spirometry and conventional spirometry were performed on all participants. We compared forced expiratory volume in one second (FEV₁), forced vital capacity (FVC), FEV₁/FVC measured by the PUS201P device with the conventional spirometer. Pearson correlation coefficient and Interclass Correlation Coefficient (ICC) were assessed to confirm the consistency of the measures from two instruments. Bland-Altman graph was created to assess the agreement of the measures from two devices.

Results

202 participants were included in this study. The ICC on FEV₁, FVC, FEV₁/FVC measured by the portable spirometer and the conventional spirometer were 0.95 (95% confidence interval [CI]: 0.94-0.96), 0.92 (95% CI: 0.90-0.94], 0.93 (95% CI: 0.91-0.95), respectively. The Bland-Altman plots showed that the mean difference between the measures from two spirometers are always located in the 95% limits of agreement.

Conclusions

Our results support that the measures from the portable spirometer and the conventional spirometer have a good agreement and reproducibility. And the portable spirometer is a reliable tool to screen and diagnose chronic airway diseases in the primary care settings.

Project description:ObjectivesObjective measurements of asthma impairment could aid teens in recognition of changes in asthma status over time. Ready access to a conventional spirometer is not realistic outside of the clinical setting. In this proof-of-concept study, we compared the performance of the VitalFlo mobile spirometer to the nSpire KoKo® sx1000 spirometer for accuracy in measuring Forced Expiratory Volume in one second (FEV1) and Forced Vital Capacity (FVC) in adolescents with asthma.MethodsTwo hundred forty pulmonary function measurements were collected from 48 adolescents with persistent asthma from the University of North Carolina's pediatric allergy and pulmonology subspecialty clinics. Participants performed spirometry with the nSpireKoKo® sx1000 spirometer and the VitalFlo spirometer during their clinic visits. 119 simulated FVC maneuvers were conducted on both devices to standardize measurements. Pearson correlations, Bland-Altman procedure, and two-sample comparison tests were performed to assess the relationship between the two spirometers.ResultsVitalFlo measurements were significantly highly correlated with nSpireKoKo® spirometer values for FEV1, (r2=0.721, [95% CI, 0.749 ± 0.120], P < 0.001) and moderately for FVC (r2= 0.617, [95% CI, 0.640 ± 0.130], P < 0.001) measurements. There were no statistically significant differences of the mean FEV1 (M = 0.00764, SD = 0.364, t(59)=0.16, P = 0.87) and FVC measurements (M = 0.00261, SD = 0.565, t(59)=0.036, P = 0.97.) between the VitalFlo and nSpireKoKo® systems. Both devices demonstrated significantly high correlation when comparing the automated FVC (r2 = 0.997, [95% CI, 1.00 ± 0.00974], P < 0.001) measurements. Bland-Altman plots did not demonstrate significant bias between devices for both FEV1 (0.00764 L) and FVC (0.00261 L) measurements.ConclusionsLung function measurements from the VitalFlo mobile spirometer were comparable to a commercially-available spirometer commonly used in clinical settings. This validated app-based spirometer for home use has the potential to improve asthma self-management.

Project description:PurposeWe evaluate the face, content, and construct validity of a portable hip arthroscopy module in a regional orthopaedic unit.MethodsParticipants were recruited from a regional orthopaedic centre, and categorized into novice (0 arthroscopies), intermediate (1-29 arthroscopies), and expert (>50 arthroscopies) groups based on reported experience in arthroscopy. Face and content validity was evaluated by feedback from users immediately following completion of modules. Objective measurements, including time taken and subjective measurements consisting of simulation software metrics including, cam lesion locations attempts, scope strikes on bone, healthy bone burred, and cam lesion burred. Scores achieved by experts were recorded, and the median score was set at the level at which proficiency was demonstrated. Participant feedback on perceived educational use was collected following completion.ResultsIn total, 20 participant results were included for analysis. Good face and content validity was expressed by participants with previous arthroscopic experience. Number of scope strikes within the simulator-derived metrics accurately discerned between levels of experience. Novices had a mean of 5 strikes per attempt (SD ±5), intermediates a mean of 5.8 strikes (SD ± 4.1). There was a significant difference between expert and novice groups (P = .01), and expert and intermediate groups (P = .002). No significant difference between overall performance scores achieved by participants in expert, intermediate, and novice groups (62% ±19 vs 55% ±22 vs 50% ±23, P = .15). This demonstrates incomplete construct validity of the simulator software-derived metrics.ConclusionsThis hip arthroscopy simulator demonstrated acceptable face and content validity, with incomplete construct validity of simulator software metrics. Participants reported high levels of satisfaction with the module, highlighting that the addition of haptic feedback would be beneficial to improve procedural steps. Incorporation of tactile feedback to the modulator components would likely enable the software to accurately delineate between levels of experience.Clinical relevanceThis study demonstrates good face and content validity. The addition of haptic feedback in a hip arthroscopy simulator may improve learning.

Project description:BackgroundWenXinWuYang, a novel portable Artificial Intelligence Electrocardiogram (AI-ECG) device, can detect many kinds of abnormal heart disease and perform a single-lead ECG, but its reliability and validity among pregnant women is unclear. The aim of this study was to assess the reliability and validity of heart rate, ECG measurements and diagnostic results by compared the portable device with a clinical 12-lead ECG among pregnant women.MethodsWe conducted a clinical study at a municipal-level maternal and child health care hospital. The pregnant women who visited the ECG room for ECG examination were invited to participate in this study. Each participant underwent three ECG recordings: one with conventional 12-lead ECG and two with WenXinWuYang ECG. The first WenXinWuYang ECG was recorded simultaneously with the 12-lead ECG. We collected heart rate, ECG measurements, and diagnostic results related to arrhythmias from both ECG devices. The data were then analyzed using Spearman rank correlation coefficients, consistency analyses, and Bland-Altman plots.ResultsThe study included 287 ECG recordings from 99 pregnant women, with a balanced distribution across different stages of pregnancy. We observed strong to moderate correlations between the two WenXinWuYang measurements for heart rate (r = 0.847), PR interval (r = 0.728), QRS duration (r = 0.636), QT interval (r = 0.836), and QTc interval (r = 0.648), with a diagnostic consistency rate exceeding 90.0%. When compared with the 12-lead ECG, the mean differences for heart rate, PR interval, QRS duration, QT interval, and QTc interval were - 0.4 ± 3.1 bpm (r = 0.957), 14.6 ± 12.4 ms (r = 0.537), 7.0 ± 8.9 ms (r = 0.136), 2.1 ± 12.0 (r = 0.774), and 6.6 ± 16.5 (r = 0.663), respectively. Although the correlation coefficient was low in QRS duration, Bland-Altman results showed moderate to strong agreement between these intervals. Sinus rhythm recognition was fully consistent with the 12-lead ECG, with higher validity in detecting arrhythmias (sensitivity 84.2%, specificity 97.5%). Similar trends existed among different stages of pregnancy.ConclusionWenXinWuYang demonstrated acceptable reliability and validity in measuring heart rate, ECG measurements, and detecting arrhythmias among pregnant women.
