Despite evidence of an increased fall risk in people with chronic obstructive pulmonary disease (COPD), there is a paucity of prospective fall data in this population. This preliminary study aimed to prospectively examine the prevalence rate, incidence rate and associated risk factors for falls in a sample of community-dwelling people with COPD over 1 year.
Forty-one participants with stable COPD (mean ± SD) aged 71 ± 8 years with a forced expiratory volume in 1 s of 45.1 ± 16.2% predicted were included. At baseline, participants' demographic, physical function and fall-related measures were documented. Falls were monitored for 12 months following initial assessments.
The prevalence of people having falls was 40% (95% CI: 24-56%); amongst these, 75% had frequent falls. The overall fall incidence rate was 1.17 falls/person-year. Risk factors associated with a higher fall incidence rate ratio (IRR) in COPD were: number of pack-years (IRR: 1.02; 95%CI: 1.00,1.04), comorbidities (IRR: 2.02; 95%CI: 1.42,3.06), number of medications (IRR: 1.15; 95%CI: 1.00,1.34), history of falls in the previous year (IRR: 1.89; 95%CI: 1.10,3.34), fear of falling (IRR: 1.08; 95% CI: 1.02,1.14) and higher score in a fall risk assessment questionnaire for older adults (IRR: 1.14; 95% CI: 1.05,1.25); P ≤ 0.05. When adjusted for age, only pack-years (P = 0.01), number of comorbidities (P < 0.001) and history of falls (P = 0.03) were related to an increased fall incidence.
These preliminary findings demonstrated the fall prevalence and incidence rate in community-dwelling people with stable COPD and identified prospective risk factors for an increased fall incidence, which suggest potential mitigation strategies.
This research output has an Altmetric Attention Score of 27. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 August 2015.
All research outputs
#1,569,336
of 27,783,697 outputs
Outputs from Respirology
#157
of 3,267 outputs
Outputs of similar age
#18,081
of 277,484 outputs
Outputs of similar age from Respirology
#2
of 59 outputs
Altmetric has tracked 27,783,697 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 94th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,267 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.5. This one has done particularly well, scoring higher than 95% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 277,484 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 93% of its contemporaries.
We're also able to compare this research output to 59 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 96% of its contemporaries.
