Patterns of Change in Pain-related Physical, Mental, and Social Health Outcomes in a Military Population.

OBJECTIVE: Military persons frequently experience pain conditions stemming from noncombat and combat injuries. This study assessed the patterns of change over time and the associations of pain intensity and interference with physical, mental, and social health domains in a military sample. METHODS: A secondary analysis of Pain Assessment Screening Tool and Outcomes Registry (PASTOR) was conducted using data collected over 10 months. Participants selected for analysis completed ≥3 assessments with an interval of ≥14 days between assessments. The Defense and Veterans Pain Rating Scale (DVPRS) measured average and worst pain intensity, and Patient-Reported Outcomes Measurement Information System (PROMIS®) T-scores measured pain and health outcomes. RESULTS: The sample (N = 190) majority reported being active duty (96%); serving in the U.S. Army (93%); and being enlisted (86%). The percent difference from assessment one to assessment three showed improvement for DVPRS average pain (-4.85%) and worst pain (-2.16%), and PROMIS Pain Interference T-score (-1.98%). Improvements were observed for all PROMIS outcomes except depression. The Defense and Veterans Pain Rating Scale average and worst pain intensity and PROMIS pain interference were strongly correlated with physical function. Multilevel models showed that an increase in average and worst pain, and pain interference were associated with a decrease in satisfaction with social roles. CONCLUSION: Analysis identified patterns of change over time in physical, mental, and social health outcomes, as well as associations important to understanding the complexities of pain. This work has implications for pain management nursing in ambulatory settings where ongoing collection and analyses of multivariable outcomes data can inform clinical care.

Musculoskeletal Pain and Headache in the Active Duty Military Population: An Integrative Review.

BACKGROUND: Since 2001, the U.S. Armed Forces' training and deployment have greatly increased, escalating the risk of injury and pain-related issues both at home station and deployment environments. AIMS: This integrative review examines the incidence, prevalence, and risk factors for musculoskeletal pain (MSP) and headaches in active duty (AD) military populations. METHODS: Peer-reviewed research published between 2001 and 2016 was identified relevant to MSP and headache in AD military personnel using MeSH terms in key biomedical databases. Inclusion criteria were: epidemiological studies examining MSP or headache as primary or secondary outcome; samples that included AD populations; and studies conducted in the theater of operations, at home station, and in military treatment or Veterans Health Administration facilities. RESULTS: Twenty-six articles met inclusion criteria. Low back pain (LBP) was the most prevalent MSP diagnosis. The incidence of LBP was 40.5 per 1,000 person-years and was comparable to nonmilitary populations. Inflammation and pain from overuse comprised the largest proportion of injury mechanism, accounting for about 82% of all injuries among nondeployed military personnel. The risk of MSP was greater for AD, female, Army, enlisted personnel, and those with greater time in a motor vehicle. Evidence suggests posttraumatic headache, occurring in up to 92% of military personnel who have sustained a mild traumatic brain injury, is associated with chronic daily headaches. IMPLICATIONS: Nurses must recognize the consequences military service can have on the development of pain. Nurses have an opportunity to positively impact the health and well-being of military and veteran populations through early recognition and treatment of pain. LINKING EVIDENCE TO ACTION: The findings from this review underscore considerable magnitude of MSP in military personnel and expose modifiable risk factors and potential targets for designing nurse-led interventions to improve pain and symptoms in military subpopulations.
