Correlation of patient-reported symptom outcomes and treadmill test outcomes after treatment for aortoiliac claudication.

ABSTRACT: To examine the relationship between objective treadmill test outcomes and subjective symptom outcomes among patients with claudication treated with stent revascularization (ST) compared with supervised exercise (SE).Five scales of the Peripheral Artery Questionnaire and Walking Impairment Questionnaire were correlated with peak walking time and treadmill claudication onset time.The correlation between change in disease-specific quality of life (QOL) and change in peak walking time differed according to treatment group, with statistically significant correlations for all five scales for the ST group and weaker trends for the SE group, only one of which was statistically significant. In contrast, improvements in disease-specific QOL correlated well with increases in claudication onset time, with no significant interaction with treatment group for any of the five scales.Disease-specific QOL results at 6 months in the Claudication: Exercise Vs. Endoluminal Revascularization (CLEVER) study show that improved maximal treadmill walking in patients with claudication treated with SE correlated poorly with self-reported symptom relief. Conversely, patients treated with ST showed good correlation between improved maximal treadmill walking and self-reported symptom improvement. The correlation between claudication onset time and self-reported symptom relief was good across treatment groups. This finding indicates that traditional objective treadmill test outcomes may not correlate well with symptom relief in patients with claudication. Future studies should investigate these data and improve understanding of patient relevance of traditional objective treadmill-based treatment outcomes.

Project description:BackgroundLumbar spinal stenosis (LSS) and peripheral arterial disease (PAD) are two distinct conditions characterized by similar symptoms including leg pain and walking limitations due to claudication. Differentiation between both origins can be difficult and characteristics such as symptom manifestations, time to relief in rest position and pain localization should be considered when determining diagnosis and the treatment plan. The objectives of this study were to compare changes in walking time to symptom change during treadmill tests and self-reported outcomes measures related to claudication, kinesophobia and global health between individuals with LSS, PAD and non-specific low back pain (nLBP).MethodFifty-five patients (23 with LSS, 14 with PAD and 18 with nLBP) were recruited from May 2018 to March 2020 to complete a treadmill walking test involving two 5-min walking tasks (Upright and Forward Leaning Trunk (FLT) Walking tasks). The speed was set at 1.9 km/h (1.2 mph), and each task was followed by a 5-min rest period. Walking time to symptom change and Total walking time were recorded during each walking task. Patients were asked to complete four questionnaires related to the impact of claudication, walking impairment, kinesiophobia and global health. One-way ANOVAs were performed to compare walking time difference from the Upright to the FLT walking tasks and to compare questionnaires results between groups.ResultsOne-way ANOVAs showed a significant difference between groups regarding difference in Walking time to symptom change between both tasks (F = 4.12, p = 0.022). The LSS group improved its Walking time to symptom change from the Upright to the FLT walking tasks more than the PAD (p = 0.34) and the nLBP group (p = 0.12). The nLBP group was less impacted by claudication and less impaired during walking compared to the LSS and PAD groups (ps < 0.001). The nLBP group also had less kinesiophobia than the LSS one (p < 0.001), but was similar to the PAD group. The global health rating was not statistically different between groups (p = 0.118).ConclusionThe test was able to distinguish neurogenic from vascular or nLBP related claudication. However, further studies are needed to validate this new treadmill walking test.Trial registrationclinicaltrials.gov ( NCT04058171 ), Registered August 15, 2019 -Registered during recruitment.

Project description:ImportanceAccurate documentation of patient symptoms in the electronic medical record (EMR) is important for high-quality patient care.ObjectiveTo explore inconsistencies between patient self-report on an Eye Symptom Questionnaire (ESQ) and documentation in the EMR.Design, setting, and participantsThis investigation was an observational study in comprehensive ophthalmology and cornea clinics at an academic institution among a convenience sample of 192 consecutive eligible patients, of whom 30 declined participation. Patients were recruited at the Kellogg Eye Center from October 1, 2015, to January 31, 2016. Patients were eligible to be included in the study if they were 18 years or older.Main outcomes and measuresConcordance of symptoms reported on an ESQ with data recorded in the EMR. Agreement of symptom report was analyzed using κ statistics and McNemar tests. Disagreement was defined as a negative symptom report or no mention of a symptom in the EMR for patients who reported moderate to severe symptoms on the ESQ. Logistic regression was used to investigate if patient factors, physician characteristics, or diagnoses were associated with the probability of disagreement for symptoms of blurry vision, pain or discomfort, and redness.ResultsA total of 162 patients (324 eyes) were included. The mean (SD) age of participants was 56.6 (19.4) years, 62.3% (101 of 162) were female, and 84.9% (135 of 159) were white. At the participant level, 33.8% (54 of 160) had discordant reporting of blurry vision between the ESQ and EMR. Likewise, documentation was discordant for reporting glare (48.1% [78 of 162]), pain or discomfort (26.5% [43 of 162]), and redness (24.7% [40 of 162]), with poor to fair agreement (κ range, -0.02 to 0.42). Discordance of symptom reporting was more frequently characterized by positive reporting on the ESQ and lack of documentation in the EMR (Holm-adjusted McNemar P < .03 for 7 of 8 symptoms except for blurry vision [P = .59]). Return visits at which the patient reported blurry vision on the ESQ had increased odds of not reporting the symptom in the EMR compared with new visits (odds ratio, 5.25; 95% CI, 1.69-16.30; Holm-adjusted P = .045).Conclusions and relevanceSymptom reporting was inconsistent between patient self-report on an ESQ and documentation in the EMR, with symptoms more frequently recorded on a questionnaire. These results suggest that documentation of symptoms based on EMR data may not provide a comprehensive resource for clinical practice or "big data" research.
