Falling is a major thing for most people but when you already have a musculoskeletal condition, it is important to know if you are at increased risk of falling and what you can do to minimise this risk.
There has been much interest in the literature on falls in older people but what are the risk factors for people with rheumatoid arthritis? We found a recent sysytematic review by a team in New Zealand that addressed this issue.
Here’s what they did
The authors searched electronic databases AMED, CINAHL, MEDLINE, Scopus and The Cochrane Library until 2013 for studies including adults with RA and where outcome measures were falls experienced in the preceding 6-12 months or prospective falls over a 12-month period. They scored studies for quality using a modified version of the Downs and Black Quality Index Tool.
Here’s what they found
- Nine articles were included with mean (range) quality scores 72% (43-93%).
- The quality assessment revealed inconsistency in falls data attainment.
- Falls incidence ranged from 10% to 50% and was independent of age, gender or RA disease duration.
- History of a prior fall (odds ratio (OR) = 3.6 and 9.8) and increasing number of medications (OR = 1.4 and 2.1) were consistently associated with falls in RA.
- Number of co-morbid conditions, swollen and tender lower extremity joints, anti-depressants, anti-hypertensives, psychotropics, pain intensity and static balance were also identified as significant fall risk factors in at least one study.
- However, the evidence was limited to a single study or conflicted with other studies.
The authors concluded
There is a wide range in reported falls incidence, which may be due to inconsistency in falls data attainment. Numerous potential fall risk factors have been evaluated, producing limited or conflicting evidence. Falls appear to be independent of age, gender and RA disease duration.
The Musculoskeletal Elf’s view
One of the main difficulties the authors of this review found was that the definition of the term “fall” was frequently missing from the included studies. This is not unusual and causes many problems in the collection and interpretation of the data.
This was the focus of the Prevention of Falls Network Europe (ProFaNE) who recommend prospective daily recording and notification of falls, with minimum monthly reporting. ProFaNE also recommend that a core set of outcome measures, including number of falls, number of fallers and fall rate, be used to improve comparability of study results.
What do you think?
- Do you record fall data for your patients with RA? If so how do you record it?
