A recent study focusing on chronic pain management for Canadian veterans has revealed a significant oversight in two decades of research: None of the studies considered the influence of sex or gender on the effectiveness of treatments. This oversight highlights a broader issue of inadequate research into the health of women and gender-diverse individuals, resulting in generalized treatment recommendations that may not be suitable for all veterans due to distinct physiological differences between genders.
Ramesh Zacharias, the president and CEO of the Chronic Pain Centre of Excellence for Canadian Veterans, expressed disappointment in the failure to address this crucial aspect of care for veterans. Canadian veterans experience chronic pain at higher rates compared to the general population, with studies showing that 40% of male veterans and 50% of female veterans suffer from chronic pain, in contrast to the national average of 20%.
Established in 2020, the Chronic Pain Centre of Excellence in Hamilton was prompted by these alarming statistics. The center conducted a review of 21 studies on opioid and rehabilitation treatments between 2000 and 2021, revealing that none of the studies took into account the participants’ sex or gender in their design or analysis. The absence of consideration for sex and gender differences in treatment outcomes creates a significant gap in care, as these factors can greatly impact chronic pain symptoms, access to care, and overall health outcomes.
Joy MacDermid, a study author and professor at Western University, emphasized that the exclusion of women from health research is not unique to veterans. Historically, women have been underrepresented, leading to broad conclusions and recommendations that may not apply universally. MacDermid highlighted the need for tailored treatments and rehabilitation programs for veterans, considering the influence of sex and gender on their military experiences.
The study also noted the importance of integrating sex and gender considerations in research practices. As a response to these findings, the Chronic Pain Centre of Excellence has incorporated sex and gender criteria in its research grant reviews. Similarly, the Canadian Institutes of Health Research mandates applicants to incorporate sex and gender considerations in their research designs when relevant.
Alice Aiken, a veteran and researcher, stressed the significance of including sex and gender in health research to better inform healthcare providers about the unique health needs of veterans. By understanding the diverse exposures faced by individuals, providers can offer more tailored and effective care. Aiken advocated for specific research on treatments for women and gender-diverse individuals to address systemic barriers in the healthcare system and improve patient outcomes.
In conclusion, the call for specialized research to enhance care for veterans is a testament to the debt owed to these individuals who have sacrificed their health and lives for the well-being of Canadians. Dr. Zacharias and other experts emphasized the importance of bringing advancements in pain management to veterans to enhance their quality of life and provide them with the care they rightfully deserve.
