Racial disparities exist in the use of electroconvulsive therapy to treat depression in older adults, found a study including a Houston VA health Care System researcher. ECT involves applying electrical current to the brain to treat mood disorders. It has proven effective in treating major depressive disorder when medication does not work. The researchers looked at nearly 700,000 patients older than 65 in a national health care database. They found that black and Hispanic patients were nearly half as likely to receive ECT, compared with white patients. While the research team acknowledges that patient preference may have played some role, they assert that efforts are needed in any case to ensure that minority groups have equal access to care.

Barriers to medication treatment for opioid use disorder

(01/14/2019) 
VA Palo Alto Health Care System researchers explored the barriers to using medication to treat opioid use disorder within VA. Evidence shows that medications such as methadone, buprenorphine, and naltrexone care be effective at treating opioid use disorder. However, only 21 percent of patients with the disorder in VA residential treatment are on these medications. According to patient and staff surveys, barriers to this type of treatment include program philosophy against medication use, lack of coordination with other treatment settings, and perceived low patient interest. Having prescribers on staff, education and support for patients and staff, and support from leadership would help facilitate medication treatment, according to survey responses.

Survey: Most Vets OK with curbing gun access during times of high suicide risk

(01/14/2019) 
Veterans receiving mental health care were in favor of voluntary programs to reduce firearm access during high-risk periods for suicide, in a VA Ann Arbor Health Care System survey. Veterans in mental health care have high rates of firearm-related suicide. Of Veterans surveyed receiving mental health care at one VA facility, 93 percent were in favor of health system interventions to limit firearm access. Of those, 75 percent were in favor of substantially limiting firearm access during times of crisis. While Veterans with household firearms were less likely to be in favor of interventions, 50 percent of the group that owns firearms still said they would participate in an intervention to limit firearm access during high-risk periods. The results suggest that VA and other health systems should consider more intensive efforts to voluntarily limit firearm access during high-risk periods, say the researchers.

Risk factors for transition from suicidal thoughts to attempts

(01/03/2019) 
A team co-led by a VA San Diego Healthcare System researcher identified characteristics that differed between service members who contemplated suicide and those who went on to make a suicide attempt. As part of the Army STARRS study, researchers surveyed more than 10,000 soldiers. They found that, compared with soldiers without suicidal thoughts, those with suicidal thoughts had higher rates of interpersonal violence, relationship problems, major depressive disorder, PTSD, and substance use disorder. Soldiers with combat trauma in the past 12 months, intermittent explosive disorder, or any college education were less likely to have suicidal thoughts. Of those with suicidal thoughts in the past 30 days, those with PTSD had higher risk of suicide attempt. Those with intermittent explosive disorder or some college education were less likely to have attempted suicide. The results show that PTSD, intermittent explosive disorder, and education should be considered when studying what makes suicidal ideation transition into suicide attempts.

Carpal tunnel syndrome treatment varies widely in VA

(01/03/2019) 
Nonsurgical therapy use for carpal tunnel syndrome varies widely within the Veterans Health Administration, according to a study by VA Ann Arbor and Palo Alto researchers. Of nearly 80,000 patients diagnosed with carpal tunnel syndrome, 8 percent had surgery. Across different facilities, between 0 and 93 percent of surgical patients received physical therapy, occupational therapy, or an orthotic. Between 1 and 67 percent of nonsurgical patients received these types of therapy. Between 0 and 100 percent of surgical patients had electrodiagnostic studies (such as X-rays or CT scans), while between 0 and 55 percent of nonsurgical patients had diagnostic scans. The results suggest that clinical practice guidelines are needed to improve the uniformity and efficiency of carpal tunnel care, say the researchers. (Journal of Hand Surgery, Dec. 19, 2018)

Probing the evidence for probiotics

(01/03/2019) 
Evidence suggests that several probiotics are effective to treat various conditions, found a study by an Edward Hines, Jr. VA Hospital researcher and colleagues. Probiotics are live bacteria and yeast that promote a healthy microorganism balance in the digestive tract. While many probiotics are on the market, evidence is lacking on their effectiveness. Researchers reviewed the current medical literature and consulted experts in the field about which probiotics have been shown to be effective. They found enough evidence to suggest that 22 different types of probiotics are effective at treating different conditions. Some probiotics had strong evidence for treatment of conditions such as antibiotic-associated diarrhea, pediatric acute diarrhea, and inflammatory bowel disease. The researchers stress that it is important to pick the correct strain, formulation, and dose of a probiotic to match a specific disease. (PLoS One, Dec. 26, 2018)

Intimate relationships may buffer against suicide

(12/26/2018) 
Strong intimate relationships could help protect service members from suicide, according to a VA Ann Arbor Health Care System study. Researchers surveyed 712 National Guard members after they returned home from deployment. The found that lower relationship satisfaction and more depressive symptoms at six months after deployment were linked to greater risk of suicide 12 months after deployment. Couple satisfaction was related to suicide risk for service members with PTSD, depression, and anxiety. The results show that the strength of an intimate relationship could serve as a buffer against suicide for patients who have these conditions, say the researchers.
