Risk of fractures in patients treated with selective serotonin reuptake inhibitors (SSRI)

Selective serotonin reuptake inhibitors (SSRIs) are recommended for the treatment of anxiety and depression in children, adolescents, and adults. Treatment with SSRIs, as well as underlying clinical depression, have been suggested to lead to an increased risk of fracture, potentially mediated by a change in bone metabolism and/or risk of falls.

SBU Enquiry Service

Consists of structured literature searches to highlight studies that can address questions received by the SBU Enquiry Service from Swedish healthcare or social service providers. We assess the risk of bias in systematic reviews and when needed also quality and transferability of results in health economic studies. Relevant references are compiled by an SBU staff member, in consultation with an external expert when needed.

Question

What systematic reviews are there on the risk of fractures or changed bone mineral density in people in long-term SSRI treatment?

Identified literature

One relevant systematic review with moderate risk of bias was identified (Table 1) [1]. The systematic review reported on the risk of fracture in adults treated with either SSRIs or Selective norepinephrine reuptake inhibitors (SNRIs).

In addition, 26 relevant primary studies reporting on either risk of fracture or changes in bone mineral density in people treated with either SSRI or SNRI were also identified (Table 2) [2–27]. The primary studies have not been assessed for risk of bias.

Khanassov et al, (2018) [1]
Selective serotonin reuptake inhibitor and selective serotonin and norepinephrine reuptake inhibitor use and risk of fractures in adults: A systematic review and meta-analysis.
Qualitative analysis:
33 studies, 11 case-control, 22 cohorts

Quantitative meta-analysis:
23 studies, 9 case control, 14 cohort

Setting:
Europe, 16 studies
US, 11 studies
Canada, 4 studies
Asia, 2 studies
Israel, 1 study		 Population:
Adults on an SSRI or SNRI, with or without a formal diagnosis of depression

Exposure:
SSRI (29 studies) or SNRI (7 studies)

Comparison:
Non-users (22 studies), other antidepressants, different level of adherence or past use (9 studies)

Outcome:
Fracture (any type of fracture at any anatomical sites either self‐reported or identified in the hospital records)		 Risk of fracture SSRI vs control:

All studies (n=23):
RR 1.67 (95% CI, 1.56 to 1.79)

Case-control studies (n=9):
RR 1.74 (95% CI, 1.50 to 2.02)

Cohort studies (n=14):
RR 1.63 (95%, CI 1.49 to 1.79)

Studies adjusted for depression (n=10):
RR 1.62 (95% CI, 1.39 to 1.90)

Studies not adjusted for depression (n=12):
RR 1.73 (95% CI, 1.60 to 1.87)

Association fracture & age (meta-regression):
OR 1.006; p=0.173
Authors' conclusion:
“There is sufficient albeit nonrandomized evidence that use of SSRIs substantially increases fracture risk in adults, from at least age 40 years and above, particularly when used over long periods; but counter to expectations, the degree of increased risk is largely independent of age.”
