Acceptability of mHealth augmentation of Collaborative Care: A mixed methods pilot study.

OBJECTIVE: To assess the feasibility and acceptability of a mobile health platform supporting Collaborative Care. METHOD: Collaborative Care patients (n=17) used a smartphone app to transmit PHQ-9 and GAD-7 scores and sensor data to a dashboard used by one care manager. Patients completed usability and satisfaction surveys and qualitative interviews at 4weeks and the care manager completed a qualitative interview. Mobile metadata on app usage was obtained. RESULTS: All patients used the app for 4weeks, but only 35% (n=6) sustained use at 8weeks. Prior to discontinuing use, 88% (n=15) completed all PHQ-9 and GAD-7 measures, with lower response rates for daily measures. Four themes emerged from interviews: understanding the purpose; care manager's role in supporting use; benefits of daily monitoring; and privacy / security concerns. Two themes were user-specific: patients' desire for personalization; and care manager burden. CONCLUSIONS: The feasibility and acceptability of the mobile platform is supported by the high early response rate, however attrition was steep. Our qualitative findings revealed nuanced participant experiences and uncovered some concerns about mobile health. To encourage retention, attention may need to be directed toward promoting patient understanding and provider engagement, and offering personalized patient experiences.

Patient-oriented health technologies: Patients' perspectives and use.

BACKGROUND: For patient-oriented mobile health tools to contribute meaningfully to improving healthcare delivery, widespread acceptance and use of such tools by patients are critical. However, little is known about patients' attitudes toward using health technology and their willingness to share health data with providers. AIMS: To investigate primary care patients' comfort sharing health information through mobile devices, and patients' awareness and use of patient portals. METHODS: Patients (n=918) who visited one of 6 primary care clinics in the Northwest US completed a survey about health technology use, medical conditions, and demographics. RESULTS: More patients were comfortable sharing mobile health information with providers than having third parties store their information (62% vs 30%, Somers D=.33, p<0.001). Patients older than 55 years were less likely to be comfortable sharing with providers (AORs 0.37-0.42, p<0.01). Only 39% of patients knew if their clinic offered a patient portal; however, of these, 67% used it. Health literacy limitations were associated with lower portal awareness (AOR=0.55, p=0.005) but not use. Portal use was higher among patients with a chronic condition (AOR= 3.18, p=0.004). CONCLUSION: Comfort, awareness, and use of health technologies were variable. Practices introducing patient-facing health technologies should promote awareness, address concerns about data security, and provide education and training, especially to older adults and those with health literacy limitations. Patient-facing health technologies provide an opportunity for delivering scalable health education and self-management support, particularly for patients with chronic conditions who are already using patient portals.

Incremental Benefit-Cost of MOMCare: Collaborative Care for Perinatal Depression Among Economically Disadvantaged Women.

OBJECTIVE: Effectiveness of collaborative care for perinatal depression has been demonstrated for MOMCare, from early pregnancy up to 15 months postpartum, for Medicaid enrollees in a public health system. MOMCare had a greater impact on reducing depression and improving functioning for women with comorbid posttraumatic stress disorder (PTSD) than for those without PTSD. This study estimated the incremental benefit and cost and the net benefit of MOMCare for women with major depression and PTSD. METHODS: A randomized trial (September 2009 to December 2014) compared the MOMCare collaborative care depression intervention (choice of brief interpersonal psychotherapy or pharmacotherapy or both) with enhanced maternity support services (MSS-Plus) in the public health system of Seattle-King County. Among pregnant women with a probable diagnosis of major depression or dysthymia (N=164), two-thirds (N=106) met criteria for probable PTSD. Blinded assessments at three, six, 12, and 18 months postbaseline included the Symptom Checklist-20 depression scale and the Cornell Services Index. Analyses of covariance estimated gain in depression free days (DFDs) by intervention and PTSD status. RESULTS: When the analysis controlled for baseline depression severity, women with probable depression and PTSD in MOMCare had 68 more depression-free days over 18 months than those in MSS-Plus (p<.05). The additional depression care cost per MOMCare participant with comorbid PTSD was $1,312. The incremental net benefit of MOMCare was positive if a DFD was valued at ≥$20. CONCLUSIONS: For women with probable major depression and PTSD, MOMCare had significant clinical benefit over MSS-Plus, with only a moderate increase in health services cost.

Depressive symptoms and adherence to cardiometabolic therapies across phases of treatment among adults with diabetes: the Diabetes Study of Northern California (DISTANCE).

OBJECTIVE: Among adults with diabetes, depression is associated with poorer adherence to cardiometabolic medications in ongoing users; however, it is unknown whether this extends to early adherence among patients newly prescribed these medications. This study examined whether depressive symptoms among adults with diabetes newly prescribed cardiometabolic medications are associated with early and long-term nonadherence. PATIENTS AND METHODS: An observational follow-up of 4,018 adults with type 2 diabetes who completed a survey in 2006 and were newly prescribed oral antihyperglycemic, antihypertensive, or lipid-lowering agents within the following year at Kaiser Permanente Northern California was conducted. Depressive symptoms were examined based on Patient Health Questionnaire-8 scores. Pharmacy utilization data were used to identify nonadherence by using validated methods: early nonadherence (medication never dispensed or dispensed once and never refilled) and long-term nonadherence (new prescription medication gap [NPMG]: percentage of time without medication supply). These analyses were conducted in 2016. RESULTS: Patients with moderate-to-severe depressive symptoms had poorer adherence than nondepressed patients (8.3% more patients with early nonadherence, P=0.01; 4.9% patients with longer NPMG, P=0.002; 7.8% more patients with overall nonadherence [medication gap >20%], P=0.03). After adjustment for confounders, the models remained statistically significant for new NPMG (3.7% difference, P=0.02). There was a graded association between greater depression severity and nonadherence for all the models (test of trend, P<0.05). CONCLUSION: Depressive symptoms were associated with modest differences in early and long-term adherence to newly prescribed cardiometabolic medications in diabetes patients. Interventions targeting adherence among adults with diabetes and depression need to address both initiation and maintenance of medication use.

Collaborative Care for Perinatal Depression Among Socioeconomically Disadvantaged Women: Adverse Neonatal Birth Events and Treatment Response.

OBJECTIVE: The study examined the effectiveness of a perinatal collaborative care intervention in moderating the effects of adverse neonatal birth events on risks of postpartum depressive symptoms and impaired functioning among women of lower socioeconomic status with antenatal depression. METHODS: A randomized controlled trial with blinded outcome assessments was conducted in ten public health centers, comparing MOMCare (choice of brief interpersonal psychotherapy, pharmacotherapy, or both) with intensive maternity support services (MSS-Plus). Participants had probable diagnoses of major depressive disorder or dysthymia during pregnancy. Generalized estimating equations estimated differences in depression and functioning measures between groups with and without adverse birth events within the treatment arms. A total of 160 women, 43% of whom experienced at least one adverse birth event, were included in the analyses. RESULTS: For women who received MOMCare, postpartum depression scores (measured with the Symptom Checklist-20) did not differ by whether or not they experienced an adverse birth event (mean±SD scores of .86±.51 for mothers with an adverse birth event and .83±.56 for mothers with no event; p=.78). For women who received MSS-Plus, having an adverse birth event was associated with persisting depression in the postpartum period (mean scores of 1.20±.0.61 for mothers with an adverse birth event and .93±.52 for mothers without adverse birth event; p=.04). Similar results were seen for depression response rates and functioning. CONCLUSIONS: MOMCare mitigated the risk of postpartum depressive symptoms and impaired functioning among women of low socioeconomic status who had antenatal depression and who experienced adverse birth events.

Centrally Assisted Collaborative Telecare for Posttraumatic Stress Disorder and Depression Among Military Personnel Attending Primary Care: A Randomized Clinical Trial.

IMPORTANCE: It is often difficult for members of the US military to access high-quality care for posttraumatic stress disorder (PTSD) and depression. OBJECTIVE: To determine effectiveness of a centrally assisted collaborative telecare (CACT) intervention for PTSD and depression in military primary care. DESIGN, SETTING, AND PARTICIPANTS: The STEPS-UP study (Stepped Enhancement of PTSD Services Using Primary Care) is a randomized trial comparing CACT with usual integrated mental health care for PTSD or depression. Patients, mostly men in their 20s, were enrolled from 18 primary care clinics at 6 military installations from February 2012 to August 2013 with 12-month follow-up completed in October 2014. INTERVENTIONS: Randomization was to CACT (n = 332) or usual care (n = 334). The CACT patients received 12 months of stepped psychosocial and pharmacologic treatment with nurse telecare management of caseloads, symptoms, and treatment. MAIN OUTCOMES AND MEASURES: Primary outcomes were severity scores on the PTSD Diagnostic Scale (PDS; scored 0-51) and Symptom Checklist depression items (SCL-20; scored 0-4). Secondary outcomes were somatic symptoms, pain severity, health-related function, and mental health service use. RESULTS: Of 666 patients, 81% were male and the mean (SD) age was 31.1 (7.7) years. The CACT and usual care patients had similar baseline mean (SD) PDS PTSD (29.4 [9.4] vs 28.9 [8.9]) and SCL-20 depression (2.1 [0.6] vs 2.0 [0.7]) scores. Compared with usual care, CACT patients reported significantly greater mean (SE) 12-month decrease in PDS PTSD scores (-6.07 [0.68] vs -3.54 [0.72]) and SCL-20 depression scores -0.56 [0.05] vs -0.31 [0.05]). In the CACT group, significantly more participants had 50% improvement at 12 months compared with usual care for both PTSD (73 [25%] vs 49 [17%]; relative risk, 1.6 [95% CI, 1.1-2.4]) and depression (86 [30%] vs 59 [21%]; relative risk, 1.7 [95% CI, 1.1-2.4]), with a number needed to treat for a 50% improvement of 12.5 (95% CI, 6.9-71.9) and 11.1 (95% CI, 6.2-50.5), respectively. The CACT patients had significant improvements in somatic symptoms (difference between mean 12-month Patient Health Questionnaire 15 changes, -1.37 [95% CI, -2.26 to -0.47]) and mental health-related functioning (difference between mean 12-month Short Form-12 Mental Component Summary changes, 3.17 [95% CI, 0.91 to 5.42]), as well as increases in telephone health contacts and appropriate medication use. CONCLUSIONS AND RELEVANCE: Central assistance for collaborative telecare with stepped psychosocial management modestly improved outcomes of PTSD and depression among military personnel attending primary care.

A Randomized Trial of Collaborative Care for Perinatal Depression in Socioeconomically Disadvantaged Women: The Impact of Comorbid Posttraumatic Stress Disorder.

OBJECTIVE: The comorbidity of posttraumatic stress disorder (PTSD) with antenatal depression poses increased risks for postpartum depression and may delay or diminish response to evidence-based depression care. In a secondary analysis of an 18-month study of collaborative care for perinatal depression, the authors hypothesized that pregnant, depressed, socioeconomically disadvantaged women with comorbid PTSD would show more improvement in the MOMCare intervention providing Brief Interpersonal Psychotherapy and/or antidepressants, compared to intensive public health Maternity Support Services (MSS-Plus). METHODS: A multisite randomized controlled trial with blinded outcome assessment was conducted in the Seattle-King County Public Health System, July 2009-January 2014. Pregnant women were recruited who met criteria for a probable diagnosis of major depressive disorder (MDD) on the Patient Health Questionnaire-9 and/or dysthymia on the MINI-International Neuropsychiatric Interview (5.0.0). The primary outcome was depression severity at 3-, 6-, 12-and 18-month follow-ups; secondary outcomes included functional improvement, PTSD severity, depression response and remission, and quality of depression care. RESULTS: Sixty-five percent of the sample of 164 met criteria for probable comorbid PTSD. The treatment effect was significantly associated with PTSD status in a group-by-PTSD severity interaction, controlling for baseline depression severity (Wald χ²1 = 4.52, P = .03). Over the 18-month follow-up, those with comorbid PTSD in MOMCare (n = 48), versus MSS-Plus (n = 58), showed greater improvement in depression severity (Wald χ²1 = 8.51, P < .004), PTSD severity (Wald χ²1 = 5.55, P < .02), and functioning (Wald χ²1 = 4.40, P < .04); higher rates of depression response (Wald χ²1 = 4.13, P < .04) and remission (Wald χ²1 = 5.17, P < .02); and increased use of mental health services (Wald χ²1 = 39.87, P < .0001) and antidepressant medication (Wald χ²1 = 8.07, P < .005). Participants without comorbid PTSD in MOMCare (n = 33) and MSS-Plus (n = 25) showed equivalent improvement on these outcomes. CONCLUSIONS: Collaborative depression care had a greater impact on perinatal depressive outcomes for socioeconomically disadvantaged women with comorbid PTSD than for those without PTSD. Findings suggest that a stepped care treatment model for high-risk pregnant women with both MDD and PTSD could be integrated into public health systems in the United States.

Input of stakeholders on reducing depressive symptoms and improving diabetes outcomes in India: Formative work for the INDEPENDENT Study.

AIMS: Depression and diabetes are highly comorbid, adversely affecting treatment adherence and resulting in poor outcomes. To improve treatment and outcomes for people dually-affected by diabetes and depression in India, we aimed to develop and test an integrated care model. In the formative phase of this INtegrated DEPrEssioN and Diabetes TreatmENT (INDEPENDENT) study, we sought stakeholder perspectives to inform culturally-sensitive adaptations of the intervention. METHODS: At our Delhi, Chennai, and Vishakhapatnam sites, we conducted focus groups for patients with diabetes and depression and interviewed healthcare workers, family members, and patients. These key informants were asked about experiences with diabetes and depression and for feedback on intervention materials. Data were analyzed using a grounded theory approach. RESULTS: Three major themes emerged that have bearing on adaptation of the proposed intervention: importance of family assistance, concerns regarding patient/family understanding of diabetes, and feedback regarding the proposed intervention (e.g. adequate time needed for implementation; training program and intervention should address stigma). CONCLUSIONS: Based on our findings, the following components would add value when incorporated into the intervention: 1) engaging families in the treatment process, 2) clear/simple written information, 3) clear non-jargon verbal explanations, and 4) coaching to help patients cope with stigma.

Rationale and design of A Trial of Sertraline vs. Cognitive Behavioral Therapy for End-stage Renal Disease Patients with Depression (ASCEND).

Major Depressive Disorder (MDD) is highly prevalent in patients with End Stage Renal Disease (ESRD) treated with maintenance hemodialysis (HD). Despite the high prevalence and robust data demonstrating an independent association between depression and poor clinical and patient-reported outcomes, MDD is under-treated when identified in such patients. This may in part be due to the paucity of evidence confirming the safety and efficacy of treatments for depression in this population. It is also unclear whether HD patients are interested in receiving treatment for depression. ASCEND (Clinical Trials Identifier Number NCT02358343), A Trial of Sertraline vs. Cognitive Behavioral Therapy (CBT) for End-stage Renal Disease Patients with Depression, was designed as a multi-center, 12-week, open-label, randomized, controlled trial of prevalent HD patients with comorbid MDD or dysthymia. It will compare (1) a single Engagement Interview vs. a control visit for the probability of initiating treatment for comorbid depression in up to 400 patients; and (2) individual chair-side CBT vs. flexible-dose treatment with a selective serotonin reuptake inhibitor, sertraline, for improvement of depressive symptoms in 180 of the up to 400 patients. The evolution of depressive symptoms will also be examined in a prospective longitudinal cohort of 90 HD patients who choose not to be treated for depression. We discuss the rationale and design of ASCEND, the first large-scale randomized controlled trial evaluating efficacy of non-pharmacologic vs. pharmacologic treatment of depression in HD patients for patient-centered outcomes.

Vasomotor Symptoms and Quality of Life Among Veteran and Non-Veteran Postmenopausal Women.

INTRODUCTION: Vasomotor symptoms (VMS), including hot flashes and night sweats, are common among postmenopausal women and are associated with reduced health related quality of life (HRQOL). PURPOSE OF THE STUDY: To determine whether Veterans are more likely to report VMS than non-Veterans, and whether the association of VMS with HRQOL varies by Veteran status. DESIGN AND METHODS: We used data from the Women's Health Initiative Observational Study, including self-reported baseline VMS presence and severity, and HRQOL at follow-up Year 3 (RAND Short Form 36-Item Health Survey). Employing generalized linear models we estimated whether Veteran status was associated with any VMS. We estimated the association between any VMS and HRQOL using linear regression, stratified by Veteran status. Interaction terms were added separately to determine whether the association varied by baseline depression, obesity, or smoking status. RESULTS: The final analyses included 77,153 postmenopausal women (2,004 Veterans). After adjustment, Veterans were no more likely than non-Veterans to report any VMS at baseline (relative risk [RR] 0.97, 95% confidence interval [CI] 0.90-1.04) or moderate to severe VMS (RR 1.03, 95% CI 0.89-1.18). Any VMS was associated with decreased HRQOL at Year 3, particularly among Veterans (mean difference range: Veterans -2.7 to -4.6, p-values < .001; non-Veterans -2.2 to -2.6, 95% CI -0.13 to -0.09, p values < .001). Baseline depression and obesity, but not smoking, amplified the negative association between VMS and HRQOL. IMPLICATIONS: Multicondition care models for postmenopausal Veteran and non-Veteran women are needed that incorporate management strategies for VMS, weight, and depression.

Association of Adolescent Depressive Symptoms With Health Care Utilization and Payer-Incurred Expenditures.

OBJECTIVE: Screening adolescents for depression is recommended by the US Preventive Services Task Force. We sought to evaluate the impact of positive depression screens in an adolescent population on health care utilization and costs from a payer perspective. METHODS: We conducted depression screening among 13- to 17-year-old adolescents enrolled in a large integrated care system using the 2- and 9-item Patient Health Questionnaires (PHQ). Health care utilization and cost data were obtained from administrative records. Chi-square, Wilcoxon rank sum, and t tests were used to test for statistical differences in outcomes between adolescents on the basis of screening status. RESULTS: Of the 4010 adolescents who completed depression screening, 3707 (92.4%) screened negative (PHQ-2 <2 or PHQ-9 <10), 186 (3.9%) screened positive for mild depression (PHQ-9 10-14), and 95 (2.4%) screened positive for moderate to severe depression (PHQ-9 ≥15). In the 12 months after screening, screen-positive adolescents were more likely than screen-negative adolescents to receive any emergency department visit or inpatient hospitalization, and they had significantly higher utilization of outpatient medical (mean ± SD, 8.3 ± 1.5 vs 3.5 ± 5.1) and mental health (3.8 ± 9.3 vs 0.7 ± 3.5) visits. Total health care system costs for screen-positive adolescents ($5083 ± $10,489) were more than twice as high as those of screen-negative adolescents ($2357 ± $7621). CONCLUSIONS: Adolescent depressive symptoms, even when mild, are associated with increased health care utilization and costs. Only a minority of the increased costs is attributable to mental health care. Implementing depression screening and evidence-based mental health services may help to better control health care costs among screen-positive adolescents.

Long-term Risk of Dementia in Persons With Schizophrenia: A Danish Population-Based Cohort Study.

IMPORTANCE: Although schizophrenia is associated with several age-related disorders and considerable cognitive impairment, it remains unclear whether the risk of dementia is higher among persons with schizophrenia compared with those without schizophrenia. OBJECTIVE: To determine the risk of dementia among persons with schizophrenia compared with those without schizophrenia in a large nationwide cohort study with up to 18 years of follow-up, taking age and established risk factors for dementia into account. DESIGN, SETTING, AND PARTICIPANTS: This population-based cohort study of more than 2.8 million persons aged 50 years or older used individual data from 6 nationwide registers in Denmark. A total of 20 683 individuals had schizophrenia. Follow-up started on January 1, 1995, and ended on January 1, 2013. Analysis was conducted from January 1, 2015, to April 30, 2015. MAIN OUTCOMES AND MEASURES: Incidence rate ratios (IRRs) and cumulative incidence proportions (CIPs) of dementia for persons with schizophrenia compared with persons without schizophrenia. RESULTS: During 18 years of follow-up, 136 012 individuals, including 944 individuals with a history of schizophrenia, developed dementia. Schizophrenia was associated with a more than 2-fold higher risk of all-cause dementia (IRR, 2.13; 95% CI, 2.00-2.27) after adjusting for age, sex, and calendar period. The estimates (reported as IRR; 95% CI) did not change substantially when adjusting for medical comorbidities, such as cardiovascular diseases and diabetes mellitus (2.01; 1.89-2.15) but decreased slightly when adjusting for substance abuse (1.71; 1.60-1.82). The association between schizophrenia and dementia risk was stable when evaluated in subgroups characterized by demographics and comorbidities, although the IRR was higher among individuals younger than 65 years (3.77; 3.29-4.33), men (2.38; 2.13-2.66), individuals living with a partner (3.16; 2.71-3.69), those without cerebrovascular disease (2.23; 2.08-2.39), and those without substance abuse (1.96; 1.82-2.11). The CIPs (95% CIs) of developing dementia by the age of 65 years were 1.8% (1.5%-2.2%) for persons with schizophrenia and 0.6% (0.6%-0.7%) for persons without schizophrenia. The respective CIPs for persons with and without schizophrenia were 7.4% (6.8%-8.1%) and 5.8% (5.8%-5.9%) by the age of 80 years. CONCLUSIONS AND RELEVANCE: Individuals with schizophrenia, especially those younger than 65 years, had a markedly increased relative risk of dementia that could not be explained by established dementia risk factors.

COLLABORATIVE CARE FOR PERINATAL DEPRESSION IN SOCIOECONOMICALLY DISADVANTAGED WOMEN: A RANDOMIZED TRIAL.

BACKGROUND: Both antenatal and postpartum depression have adverse, lasting effects on maternal and child well-being. Socioeconomically disadvantaged women are at increased risk for perinatal depression and have experienced difficulty accessing evidence-based depression care. The authors evaluated whether "MOMCare,"a culturally relevant, collaborative care intervention, providing a choice of brief interpersonal psychotherapy and/or antidepressants, is associated with improved quality of care and depressive outcomes compared to intensive public health Maternity Support Services (MSS-Plus). METHODS: A randomized multisite controlled trial with blinded outcome assessment was conducted in the Seattle-King County Public Health System. From January 2010 to July 2012, pregnant women were recruited who met criteria for probable major depression and/or dysthymia, English-speaking, had telephone access, and ≥18 years old. The primary outcome was depression severity at 3-, 6-, 12-, 18-month postbaseline assessments; secondary outcomes included functional improvement, PTSD severity, depression response and remission, and quality of depression care. RESULTS: All participants were on Medicaid and 27 years old on average; 58% were non-White; 71% were unmarried; and 65% had probable PTSD. From before birth to 18 months postbaseline, MOMCare (n = 83) compared to MSS-Plus participants (n = 85) attained significantly lower levels of depression severity (Wald's χ(2) = 6.09, df = 1, P = .01) and PTSD severity (Wald's χ(2) = 4.61, df = 1, P = .04), higher rates of depression remission (Wald's χ(2) = 3.67, df = 1, P = .05), and had a greater likelihood of receiving ≥4 mental health visits (Wald's χ(2) = 58.23, df = 1, P < .0001) and of adhering to antidepressants in the prior month (Wald's χ(2) = 10.00, df = 1, P < .01). CONCLUSION: Compared to MSS-Plus, MOMCare showed significant improvement in quality of care, depression severity, and remission rates from before birth to 18 months postbaseline for socioeconomically disadvantaged women. Findings suggest that evidence-based perinatal depression care can be integrated into the services of a county public health system in the United States.

Demographic, clinical and psychosocial factors identify a high-risk group for depression screening among predominantly Hispanic patients with Type 2 diabetes in safety net care.

OBJECTIVE: Identify biopsychosocial factors associated with depression for patients with Type 2 diabetes. METHOD: A quasi-experimental clinical trial of 1293 patients was predominantly Hispanic (91%) female (62%), mean age 53 and average diabetes duration 10 years; 373 (29%) patients were depressed and assessed by Patient Health Questionnaire-9. Demographic, baseline clinical and psychosocial variables were compared between depressed and nondepressed patients. RESULTS: Bivariate analyses found depression significantly associated (p<0.05) with female gender, diabetes emotional burden and regimen distress, BMI ≥ 30, lack of an A1C test, diabetes duration, poor self-care, number of diabetes symptoms and complications, functional and physical characteristics (pain, self-rated health condition, Short-Form Health Survey SF-physical, disability score and comorbid illnesses), as well as higher number of ICD-9 diagnoses and emergency room use. A multivariable regression model with stepwise selection identified six key risk factors: greater disability, diabetes symptoms and regimen distress, female gender, less diabetes self-care and lack of A1C. In addition, after controlling for identified six factors, the number of psychosocial stressors significantly associated with increased risk of depression (adjusted odds ratio=1.37, 95% confidence intervals: 1.18-1.58, p<.0001). CONCLUSION: Knowing biopsychosocial factors could help primary care physicians and endocrinologists identify a high-risk group of patients needing depression screening.

Effect of depression and diabetes mellitus on the risk for dementia: a national population-based cohort study.

IMPORTANCE: Although depression and type 2 diabetes mellitus (DM) may independently increase the risk for dementia, no studies have examined whether the risk for dementia among people with comorbid depression and DM is higher than the sum of each exposure individually. OBJECTIVE: To examine the risk for all-cause dementia among persons with depression, DM, or both compared with persons with neither exposure. DESIGN, SETTING, AND PARTICIPANTS: We performed a national population-based cohort study of 2 454 532 adults, including 477 133 (19.4%) with depression, 223 174 (9.1%) with DM, and 95 691 (3.9%) with both. We included all living Danish citizens 50 years or older who were free of dementia from January 1, 2007, through December 31, 2013 (followed up through December 31, 2013). Dementia was ascertained by physician diagnosis from the Danish National Patient Register or the Danish Psychiatric Central Register and/or by prescription of a cholinesterase inhibitor or memantine hydrochloride from the Danish National Prescription Registry. Depression was ascertained by psychiatrist diagnosis from the Danish Psychiatric Central Research Register or by prescription of an antidepressant from the Danish National Prescription Registry. Diabetes mellitus was identified using the National Diabetes Register. MAIN OUTCOMES AND MEASURES: We estimated the risk for all-cause dementia associated with DM, depression, or both using Cox proportional hazards regression models that adjusted for potential confounding factors (eg, demographics) and potential intermediates (eg, medical comorbidities). RESULTS: During 13 834 645 person-years of follow-up, 59 663 participants (2.4%) developed dementia; of these, 6466 (10.8%) had DM, 15 729 (26.4%) had depression, and 4022 (6.7%) had both. The adjusted hazard ratio for developing all-cause dementia was 1.83 (95% CI, 1.80-1.87) for persons with depression, 1.20 (95% CI, 1.17-1.23) for persons with DM, and 2.17 (95% CI, 2.10-2.24) for those with both compared with persons who had neither exposure. The excess risk for all-cause dementia observed for individuals with comorbid depression and DM surpassed the summed risk associated with each exposure individually, especially for persons younger than 65 years (hazard ratio, 4.84 [95% CI, 4.21-5.55]). The corresponding attributable proportion due to the interaction of comorbid depression and DM was 0.25 (95% CI, 0.13-0.36; P < .001) for those younger than 65 years and 0.06 (95% CI, 0.02-0.10; P = .001) for those 65 years or older. CONCLUSIONS AND RELEVANCE: Depression and DM were independently associated with a greater risk for dementia, and the combined association of both exposures with the risk for all-cause dementia was stronger than the additive association.

Effectiveness of a telehealth service delivery model for treating attention-deficit/hyperactivity disorder: a community-based randomized controlled trial.

OBJECTIVE: To test the effectiveness of a telehealth service delivery model for the treatment of children with attention-deficit/hyperactivity disorder (ADHD) that provided pharmacological treatment and caregiver behavior training. METHOD: The Children's ADHD Telemental Health Treatment Study (CATTS) was a randomized controlled trial with 223 children referred by 88 primary care providers (PCPs) in 7 communities. Children randomized to the experimental telehealth service model received 6 sessions over 22 weeks of combined pharmacotherapy, delivered by child psychiatrists through videoconferencing, and caregiver behavior training, provided in person by community therapists who were supervised remotely. Children randomized to the control service delivery model received treatment with their PCPs augmented with a telepsychiatry consultation. Outcomes were diagnostic criteria for ADHD and oppositional defiant disorder (ODD) and role performance on the Vanderbilt ADHD Rating Scale (VADRS) completed by caregivers (VADRS-Caregivers) and teachers (VADRS-Teachers) and impairment on the Columbia Impairment Scale-Parent Version (CIS-P). Measures were completed at 5 assessments over 25 weeks. RESULTS: Children in both service models improved. Children assigned to the telehealth service model improved significantly more than children in the augmented primary care arm for VADRS-Caregiver criteria for inattention (χ(2)[4] = 19.47, p < .001), hyperactivity (χ(2)[4] = 11.91, p = .02), combined ADHD (χ(2)[4] = 14.90, p = .005), ODD (χ(2)[4] = 10.05, p = .04), and VADRS-Caregiver role performance (χ(2) [4] = 12.40, p = .01) and CIS-P impairment (χ(2)[4] = 20.52, p < .001). For the VADRS-Teacher diagnostic criteria, children in the telehealth service model had significantly more improvement in hyperactivity (χ(2)[4] = 11.28, p = .02) and combined ADHD (χ(2)[4] = 9.72, p = .045). CONCLUSION: The CATTS trial demonstrated the effectiveness of a telehealth service model to treat ADHD in communities with limited access to specialty mental health services.

Associations between sex and incident chronic kidney disease in a prospective diabetic cohort.

AIM: Women with diabetes have a higher prevalence of chronic kidney disease (CKD) risk factors compared with men, but whether they are at higher risk for incident CKD remains uncertain. METHODS: This was a prospective, observational cohort study of 1464 patients with diabetes and normal renal function, recruited from primary care clinics at a vertically integrated healthcare system in Seattle, WA, USA. The primary predictor was sex. Incident CKD was defined by an estimated glomerular filtration rate (eGFR) <60 mL/min per 1.73 m(2) by Chronic Kidney Disease-Epidemiology equations or sex-specific microalbuminuria (urine albumin/creatinine ratio ≥25 mg/g for women or ≥17 mg/g for men). RESULTS: Of the 1464 patients (52.0% women), CKD incidence rates were 154.0 and 144.3 cases per 1000 patient-years for women and men, respectively. In the competing risks regression, women had an increased risk of incident CKD (sub-hazard ratio 1.37, 95% confidence interval (CI) 1.17, 1.60) compared with men after adjustment for demographics, baseline eGFR and duration of diabetes, which persisted after additional adjustment for CKD risk factors, depressive symptoms and diabetes self-care (sub-hazard ratio 1.35, 95% CI 1.15, 1.59). Sex differences in incident CKD were consistent across age groups and appeared to be driven by differences in the development of low eGFR rather than microalbuminuria. CONCLUSION: Women with diabetes had a higher risk of incident CKD compared with men, which could not be entirely explained by differences in biologic CKD risk factors, depression or diabetes self-care. Additional work is needed determine if these sex differences contribute to worse outcomes in women with diabetes.

The association of depression, cognitive impairment without dementia, and dementia with risk of ischemic stroke: a cohort study.

OBJECTIVE: To determine if depression, cognitive impairment without dementia (CIND), and/or dementia are each independently associated with risk of ischemic stroke and to identify characteristics that could modify these associations. METHODS: This retrospective-cohort study examined a population-based sample of 7031 Americans older than 50 years participating in the Health and Retirement Study (1998-2008) who consented to have their interviews linked to their Medicare claims. The eight-item Center for Epidemiologic Studies Depression Scale and/or International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) depression diagnoses were used to identify baseline depression. The Modified Telephone Interview for Cognitive Status and/or ICD-9-CM dementia diagnoses were used to identify baseline CIND or dementia. Hospitalizations for ischemic stroke were identified via ICD-9-CM diagnoses. RESULTS: After adjusting for demographics, medical comorbidities, and health-risk behaviors, CIND alone (odds ratio [OR] = 1.37, 95% confidence interval [CI] = 1.11-1.69) and co-occurring depression and CIND (OR = 1.65, 95% CI = 1.24-2.18) were independently associated with increased odds of ischemic stroke. Depression alone was not associated with odds of ischemic stroke (OR = 1.11, 95% CI = 0.88-1.40) in unadjusted analyses. Neither dementia alone (OR = 1.09, 95% CI = 0.82-1.45) nor co-occurring depression and dementia (OR = 1.25, 95% CI = 0.89-1.76) were associated with odds of ischemic stroke after adjusting for demographics. CONCLUSIONS: CIND and co-occurring depression and CIND are independently associated with increased risk of ischemic stroke. Individuals with co-occurring depression and CIND represent a high-risk group that may benefit from targeted interventions to prevent stroke.

Thirty-Day Mortality After Infection Among Persons With Severe Mental Illness: A Population-Based Cohort Study in Denmark.

OBJECTIVE: Persons with severe mental illness die 15-20 years earlier on average than persons without severe mental illness. Although infection is one of the leading overall causes of death, no studies have evaluated whether persons with severe mental illness have a higher mortality after infection than those without. METHOD: The authors studied mortality rate ratios and cumulative mortality proportions after an admission for infection for persons with severe mental illness compared with persons without severe mental illness by linking data from Danish national registries. RESULTS: The cohort consisted of all persons hospitalized for infection during the period 1995-2011 in Denmark (N=806,835), of whom 11,343 persons had severe mental illness. Within 30 days after an infection, 1,052 (9.3%) persons with a history of severe mental illness and 58,683 (7.4%) persons without a history of severe mental illness died. Thirty-day mortality after any infection was 52% higher in persons with severe mental illness than in persons without (mortality rate ratio=1.52, 95% CI=1.43-1.61). Mortality was increased for all infections, and the mortality rate ratios ranged from 1.27 (95% CI=1.15-1.39) for persons hospitalized for sepsis to 2.61 (95% CI=1.69-4.02) for persons hospitalized for CNS infections. Depending on age, 1.7 (95% CI=1.2-2.2) to 2.9 (95% CI=2.0-3.7) more deaths were observed within 30 days after an infection per 100 persons with a history of severe mental illness compared with 100 persons without such a history. CONCLUSIONS: Persons with severe mental illness have a markedly elevated 30-day mortality after infection. Some of these excess deaths may be prevented by offering individualized and targeted interventions.
