Emergency Medical Services Compliance With Prehospital Stroke Quality Metrics Is Associated With Faster Stroke Evaluation and Treatment.

BACKGROUND: Emergency medical services (EMS) is an important link in the stroke chain of recovery. Various prehospital quality metrics have been proposed for prehospital stroke care, but their individual impact is uncertain. We sought to measure associations between EMS quality metrics and downstream stroke care. METHODS: This is a retrospective analysis of a cohort of EMS-transported stroke patients assembled through a linkage between Michigan's EMS and stroke registries. We used multivariable regression to quantify the independent associations between EMS quality metric compliance (dispatch within 90 seconds of 911 call, prehospital stroke screen documentation [Prehospital stroke scale], glucose check, last known well time, maintenance of scene times ≤15 minutes, hospital prenotification, and intravenous line placement) and shorter door-to-CT times (door-to-CT ≤25), accounting for EMS recognition, age, sex, race, stroke subtype, severity, and duration of symptoms. We then developed a simple EMS quality score based on metrics associated with early CT and examined its associations with hospital stroke evaluation times, treatment, and patient outcomes. RESULTS: Five thousand seven hundred seven EMS-transported stroke cases were linked to prehospital records from January 2018 through June 2019. In multivariable analysis, prehospital stroke scale documentation (adjusted odds ratio, 1.4 [1.2-1.6]), glucose check (1.3 [1.1-1.6]), on-scene time ≤15 minutes (1.6 [1.4-1.9]), hospital prenotification ([2.0 [1.4-2.9]), and intravenous line placement (1.8 [1.5-2.1]) were independently associated with a door-to-CT ≤25 minutes. A 5-point quality score (1 point for each element) was therefore developed. In multivariable analysis, a 1-point higher EMS quality score was associated with a shorter time from EMS contact to CT (-9.2 [-10.6 to -7.8] minutes; P<0.001) and thrombolysis (-4.3 [-6.4 to -2.2] minutes; P<0.001), and higher odds of discharge to home (adjusted odds ratio, 1.1 [1.0-1.2]; P=0.002). CONCLUSIONS: Five EMS actions recommended by national guidelines were associated with rapid CT imaging. A simple quality score derived from these measures was also associated with faster stroke evaluation, greater odds of reperfusion treatment, and discharge to home.

High Pesticide Exposure Events and Dream-Enacting Behaviors Among US Farmers.

BACKGROUND: Dream-enacting behavior is a characteristic feature of rapid eye movement sleep behavior disorder, the most specific prodromal marker of synucleinopathies. Pesticide exposure may be associated with dream-enacting behaviors, but epidemiological evidence is limited. OBJECTIVES: To examine high pesticide exposure events in relation to dream-enacting behaviors among farmers in the Agricultural Health Study. METHODS: We conducted multivariable logistic regression analyses to examine high pesticide exposure events reported from 1993 to 1997 in relation to dream-enacting behaviors assessed from 2013 to 2015 among 11,248 farmers (age 47 ± 11 years). RESULTS: A history of dream-enacting behaviors was reported by 939 (8.3%) farmers. Compared with farmers who did not report any high pesticide exposure event, those who reported were more likely to endorse dream-enacting behaviors 2 decades later (odds ratio = 1.75; 95% confidence interval [CI], 1.49-2.05). The association appeared stronger when there was a long delay in washing with soap and water after the event (2.63 [95% CI, 1.62-4.27] for waiting >6 hours vs. 1.71 [95% CI, 1.36-2.15] for washing within 30 minutes) and when the exposure involved the respiratory or digestive tract (2.04 [95% CI, 1.62-2.57] vs. 1.58 [95% CI, 1.29-1.93] for dermal contact only). In the analyses of specific pesticides involved, we found positive associations with two organochlorine insecticides (dichlorodiphenyltrichloroethane and lindane), four organophosphate insecticides (phorate, ethoprop, terbufos, and parathion), two herbicides (alachlor and paraquat), and fungicides as a group. CONCLUSIONS: This study provides the first epidemiological evidence that high pesticide exposures may be associated with a higher risk of dream-enacting behaviors. © 2022 International Parkinson and Movement Disorder Society.

Emulating 3 Clinical Trials That Compare Stroke Rehabilitation at Inpatient Rehabilitation Facilities With Skilled Nursing Facilities.

OBJECTIVE: To inform the design of a potential future randomized controlled trial (RCT), we emulated 3 trials where patient-level outcomes were compared after stroke rehabilitation at inpatient rehabilitation facilities (IRFs) with skilled nursing facilities (SNFs). DESIGN: Trials were emulated using a 1:1 matched propensity score analysis. The 3 trials differed because facilities from rehabilitation networks with different case volumes were compared. Rehabilitation network case volumes were based on the number of patients with stroke that each hospital discharged to each specific IRF or SNF. Trial 1 included 60,529 patients from all networks, trial 2 included 34,444 patients from networks with medium and large case volumes (ie, ≥5 patients), and trial 3 included 19,161 patients from networks with large case volumes (ie, ≥10 patients). The E values were calculated to estimate the minimum strength that an unmeasured confounder would need to be to nullify the results. SETTING: A national sample of IRFs and SNFs from across the United States. PARTICIPANTS: Fee-for-service Medicare patients with acute stroke who received IRF or SNF based rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: One-year successful community discharge (home for >30 consecutive days) and all-cause mortality. RESULTS: Overall, 29,500, 15,156, and 7450 patients were matched for trials 1, 2, and 3. For 1-year successful community discharge, absolute risk differences for IRF patients were 0.21 (95% CI, 0.20-0.22), 0.17 (95% CI, 0.16-0.19), and 0.12 (95% CI, 0.10-0.14) in trials 1, 2, and 3, respectively. For 1-year all-cause mortality, corresponding risk differences were -0.11 (95% CI, -0.12 to -0.11), -0.11 (95% CI, -0.12 to -0.09), and -0.08 (95% CI, -0.10 to -0.06). The E values indicated that a moderately sized unmeasured confounder, with a relative risk of 1.6-2.0 would nullify differences in successful community discharge. CONCLUSIONS: IRF patients had superior outcomes, but differences were attenuated when IRFs and SNFs from larger rehabilitation networks were compared. The vulnerability of the findings to unmeasured confounding supports the need for an RCT.

Rationale for a Clinical Trial That Compares Acute Stroke Rehabilitation at Inpatient Rehabilitation Facilities to Skilled Nursing Facilities: Challenges and Opportunities.

In the United States, approximately 400,000 patients with acute stroke are discharged annually to inpatient rehabilitation facilities (IRFs) or skilled nursing facilities (SNFs). Typically, IRFs provide time-intensive therapy for an average of 2-3 weeks, whereas SNFs provide more moderately intensive therapy for 4-5 weeks. The factors that influence discharge to an IRF or SNF are multifactorial and poorly understood. The complexity of these factors in combination with subjective clinical indications contributes to large variations in the use of IRFs and SNFs. This has significant financial implications for health care expenditure, given that stroke rehabilitation at IRFs costs approximately double that at SNFs. To control health care spending without compromising outcomes, the Institute of Medicine has stated that policy reforms that promote more efficient use of IRFs and SNFs are critically needed. A major barrier to the formulation of such policies is the highly variable and low-quality evidence for the comparative effectiveness of IRF- vs SNF-based stroke rehabilitation. The current evidence is limited by the inability of observational data to control for residual confounding, which contributes to substantial uncertainty around any magnitude of benefit for IRF- vs SNF-based care. Furthermore, it is unclear which specific patients would receive the most benefit from each setting. A randomized controlled trial addresses these issues, because random treatment allocation facilitates an equitable distribution of measured and unmeasured confounders. We discuss several measurement, practical, and ethical issues of a trial and provide our rationale for design suggestions that overcome some of these issues.

Costs of a Train-the-Trainer Program to Teach Primary Care Faculty Mental Health Care.

BACKGROUND: Mental health care must improve in this country. With the worsening shortage of psychiatrists and other mental health professionals, the next generation of physicians in primary care will need to be better trained in mental health care. OBJECTIVES: We estimate the direct cost of implementing an evidence-based Train-the-Trainer (3T) program to disseminate mental health training to allopathic medical school faculty; once trained, faculty can teach a much-enhanced curriculum of mental health care to medical students and residents. METHODS: A combination of published standardized unit costs and an activity-based costing approach is used to estimate the direct costs (labor and nonlabor) for implementing the 3T program. RESULTS: The estimated direct cost of implementing the 3T program at one prototypical school, including the 12-month start-up period (1.1 million) and 18-month rollout period (8.6 million), is ∼9.7 million dollars. CONCLUSIONS: Successfully adopted in all US allopathic medical schools, the 3T program will provide over 3800 attitudinally competent and mental health skills-qualified primary care faculty members. They would then be available to train nearly 100,000 medical students per year and 55,000 primary care residents to be as competent in basic mental health care as in medical care. This 3T program will begin to meet the needs each year for the millions of adults with major mental disorders that now are largely unrecognized and untreated.

A Survey of Primary Care Practices on Their Use of the Intensive Behavioral Therapy for Obese Medicare Patients.

OBJECTIVE: To fill the gap in knowledge on systematic differences between primary care practices (PCP) that do or do not provide intensive behavioral therapy (IBT) for obese Medicare patients. METHODS: A mixed modality survey (paper and online) of primary care practices obtained from a random sample of Medicare databases and a convenience sample of practice-based research network practices. KEY RESULTS: A total of 287 practices responded to the survey, including 140 (7.4% response rate) from the random sample and 147 (response rate not estimable) from the convenience sample. We found differences between the IBT-using and non-using practices in practice ownership, patient populations, and participation in Accountable Care Organizations. The non-IBT-using practices, though not billing for IBT, did offer some other assistance with obesity for their patients. Among those who had billed for IBT, but stopped billing, the most commonly cited reason was billing difficulties. Many providers experienced denied claims due to billing complexities. CONCLUSIONS: Although the Centers for Medicare and Medicaid Services established payment codes for PCPs to deliver IBT for obesity in 2011, very few providers submitted fee-for-service claims for these services after almost 10 years. A survey completed by both a random and convenience sample of practices using and not using IBT for obesity payment codes revealed that billing for these services was problematic, and many providers that began using the codes discontinued using them over the past 7 years.

Changes in Body Composition Before and After Parkinson's Disease Diagnosis.

BACKGROUND: Weight loss is common in Parkinson's disease (PD). However, little is known about when it starts, how PD changes as it progresses, and whether there is a differential loss of lean or fat mass. The objective of this study was to examine how body composition changes before and after PD diagnosis. METHODS: In the Health, Aging, and Body Composition study (n = 3075; age range, 70-79 years), body composition was assessed using dual-energy x-ray absorptiometry on an annual or biennial basis from year 1 to year 10. For each PD case each year, we calculated the difference between their actual body composition measures and expected values had they not developed PD. Using linear mixed models with crossed random effects, we further examined the trend of change in body composition measures before and after PD diagnosis. RESULTS: A total of 80 PD cases were identified in this cohort. Compared with their expected values, PD cases began to lose total and fat mass about 6-7 years before diagnosis, although the differences were not statistically significant until 3-5 years after diagnosis. The loss was substantial and persistent, with statistically significant trends of loss for total body mass (P = 0.008), fat mass (P = 0.001), and percentage fat (P < 0.001). In comparison, lean mass was stable throughout the follow-up (P = 0.16). Overall, 96% of the body mass loss in PD cases was from the loss of fat mass. CONCLUSIONS: In this longitudinal analysis with objective measures of body composition, we found persistent weight loss in PD cases, predominantly in fat mass, starting a few years before diagnosis. © 2021 International Parkinson and Movement Disorder Society.

Identification of spliceosome components pivotal to breast cancer survival.

Cancer cells employ alternative splicing (AS) to acquire splicing isoforms favouring their survival. However, the causes of aberrant AS in breast cancer are poorly understood. In this study, the METABRIC (Molecular Taxonomy of Breast Cancer International Consortium) data were analysed with univariate feature selection. Of 122 analysed spliceosome components, U2SURP, PUF60, DDX41, HNRNPAB, EIF4A3, and PPIL3 were significantly associated with breast cancer survival. The top 4 four genes, U2SURP, PUF60, DDX41, and HNRNPAB, were chosen for further analyses. Their expression was significantly associated with cancer molecular subtype, tumour stage, tumour grade, overall survival (OS), and cancer-specific survival in the METABRIC data. These results were verifiable using other cohorts. The Cancer Genome Atlas data unveiled the elevated expression of PUF60, DDX41, and HNRNPAB in tumours compared with the normal tissue and confirmed the differential expression of the four genes among cancer molecular subtypes, as well as the associations of U2SURP, PUF60, and DDX41 expression with tumour stage. A meta-analysis data verified the associations of U2SURP, PUF60, and HNRNPAB expression with tumour grade, the associations of PUF60, DDX41, and HNRNPAB expression with OS and distant metastasis-free survival, and the associations of U2SURP and HNRNPAB expression with relapse-free survival. Experimentally, we demonstrated that inhibiting the expression of the four genes separately suppressed cell colony formation and slowed down cell growth considerably in breast cancer cells, but not in immortal breast epithelial cells. In conclusion, we have identified U2SURP, PUF60, DDX41, and HNRNPAB are spliceosome-related genes pivotal for breast cancer survival.

Race/Ethnic and Stroke Subtype Differences in Poststroke Functional Recovery After Acute Rehabilitation.

OBJECTIVE: Significant racial/ethnic disparities in poststroke function exist, but whether these disparities vary by stroke subtype is unknown. Study goals were to (1) determine if racial/ethnic disparities in the recovery of poststroke function varied by stroke subtype and (2) identify confounding factors associated with these racial/ethnic disparities. DESIGN: Secondary analysis of the 1-year Stroke Recovery in Underserved Populations Cohort Study. SETTING: Eleven inpatient rehabilitation facilities (IRFs) across the United States. PARTICIPANTS: A total of 1066 patients (n=868 with ischemic stroke and n=198 with hemorrhagic stroke, N=1066) who self-identified as White (n=813), Black (n=183), or Hispanic (n=70). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM scores at IRF admission, discharge, 3 months, and 12 months were modeled using multivariable mixed effects longitudinal regression. RESULTS: Compared with White patients, Black (-6.1 and -4.6) and Hispanic (-10.1 and -9.9) patients had significantly lower FIM scores at 3 and 12 months, respectively. A significant (P<.01) 3-way interaction (race/ethnic*subtype*time) indicated that disparities varied by stroke subtype. The stroke subtype differences were most prominent for Black-White disparities because disparities in hemorrhagic stroke were present at IRF admission (vs 3 months for ischemic stroke). Additionally, at 12 months, the magnitude of Black-White disparities was over 3 times larger for hemorrhagic stroke (-10.4) than ischemic stroke (-3.1). Age primarily influenced Black-White disparities (especially for hemorrhagic stroke), but factors that influenced Hispanic-White disparities were not identified. Sensitivity analyses showed that there were stroke subtype differences in racial/ethnic disparities for cognitive (but not motor) function, and results were robust to adjustments for missing data because of attrition. CONCLUSIONS: There are significant differences between stroke subtypes in the timing and magnitude of Black-White disparities in poststroke function. Age was a major confounding factor for Black-White disparities (particularly for hemorrhagic stroke). Overall, Hispanic patients had the lowest levels of poststroke function, and more work is needed to identify significant factors that influence Hispanic-White disparities.

Relationship Between Poor Olfaction and Mortality Among Community-Dwelling Older Adults: A Cohort Study.

Background: Poor olfaction is common among older adults and has been linked to higher mortality. However, most studies have had a relatively short follow-up and have not explored potential explanations. Objective: To assess poor olfaction in relation to mortality in older adults and to investigate potential explanations. Design: Community-based prospective cohort study. Setting: 2 U.S. communities. Participants: 2289 adults aged 71 to 82 years at baseline (37.7% black persons and 51.9% women). Measurements: Brief Smell Identification Test in 1999 or 2000 (baseline) and all-cause and cause-specific mortality at 3, 5, 10, and 13 years after baseline. Results: During follow-up, 1211 participants died by year 13. Compared with participants with good olfaction, those with poor olfaction had a 46% higher cumulative risk for death at year 10 (risk ratio, 1.46 [95% CI, 1.27 to 1.67]) and a 30% higher risk at year 13 (risk ratio, 1.30 [CI, 1.18 to 1.42]). Similar associations were found in men and women and in white and black persons. However, the association was evident among participants who reported excellent to good health at baseline (for example, 10-year mortality risk ratio, 1.62 [CI, 1.37 to 1.90]) but not among those who reported fair to poor health (10-year mortality risk ratio, 1.06 [CI, 0.82 to 1.37]). In analyses of cause-specific mortality, poor olfaction was associated with higher mortality from neurodegenerative and cardiovascular diseases. Mediation analyses showed that neurodegenerative diseases explained 22% and weight loss explained 6% of the higher 10-year mortality among participants with poor olfaction. Limitation: No data were collected on change in olfaction and its relationship to mortality. Conclusion: Poor olfaction is associated with higher long-term mortality among older adults, particularly those with excellent to good health at baseline. Neurodegenerative diseases and weight loss explain only part of the increased mortality. Primary Funding Source: National Institutes of Health and Michigan State University.

Factors Influencing Received Social Support Among Emerging Adults With Inflammatory Bowel Disease: A Cross-Sectional Study.

The majority of research among individuals with inflammatory bowel disease (IBD) focuses on perceived social support. A gap exists regarding the role of received social support in self-management enhancement. The purpose of this study was to examine specific contextual factors (individual, condition-specific, and emerging adulthood factors) that influence received social support (total, informational, emotional, and tangible) among emerging adults (ages 18-29 years) with IBD. A convenience sample of 61 emerging adults with a diagnosis of IBD was obtained. An association was found between high total received social support and several individual factors such as being closer to the younger end of the age range (ages 18-29 years), married, and fully employed. When controlling for time since diagnosis and symptom interference, high tangible received social support was associated with the use of immunomodulator and biological medications. Emerging adulthood factors were not associated with total or any types of received social support. Future research could examine differences between types of social support and self-management behaviors. These findings contribute a new direction for intervention development with a focus on individual and condition-specific factors to enhance received social support and ultimately health outcomes for individuals with IBD.

Economic conditions during pregnancy and preterm birth: A maternal fixed-effects analysis.

BACKGROUND: Making causal inference regarding impacts of macrolevel economic conditions during pregnancy on pregnancy outcomes is hampered by the presence of unmeasured variables that may influence women's probability of giving birth under certain economic conditions (ie, exposure) as well as her pregnancy outcomes. Maternal fixed-effects (FE) analyses, in which the association between exposure and outcomes is estimated within mothers who had discordant outcomes, can control for such unmeasured variables when they are invariant across pregnancies. METHODS: We utilised a maternally linked data set of all singleton births in Michigan from 1990 to 2012 (n = 2 657 272 for full sample; n = 269 943 for FE analytic sample) to examine the relationship between state-level unemployment rates during pregnancy and preterm birth (PTB, <37 weeks' gestation). Measured maternal characteristics that change across pregnancies, for example, age, marital status, education, parity, and infant sex, were included as covariates in the model. RESULTS: Using an FE approach, we found that each one percentage point increase in state unemployment in the first trimester of pregnancy was associated with a modest 3% increase in odds of PTB. Our results were consistent with previously published results in a national sample and held across random- versus fixed-effect models, analytic samples, and outcome measures. CONCLUSIONS: Our findings provide further evidence that economic downturn during early pregnancy may be associated with modest increases in PTB.

Healthcare service utilization and work-related productivity in reflexology intervention for advanced breast cancer women.

PURPOSE: This project's purpose was to determine the effects of a home-based reflexology intervention on symptom-related use of health services and work-related productivity during the 11-week study. METHODS: A total of 256 patients were randomized to four weekly reflexology sessions (each lasting 30 min, delivered by lay caregivers who received two training sessions by a professional reflexologist) or attention control. The Conventional Health Service and Productivity Costs Form was used to collect information on health service utilization and out-of-pocket expenditure of symptom management. The Health and Work Performance Questionnaire was used to measure workplace performance for patients during the study period. We used weighted and unweighted logistic and linear regression analyses. RESULTS: Patients in the reflexology group were less likely to have hospital visits compared to the control group in the weighted unadjusted (odds ratio [OR] = 0.49; 95% confidence interval [CI] = [0.25, 0.97]), unweighted adjusted (OR = 0.35; 95% CI = [0.16, 0.75]), and weighted adjusted (OR = 0.30, 95% CI = [0.13, 0.66]) logistic regressions. Compared to attention control, patients in the reflexology group had lower relative absenteeism in the unweighted adjusted (- 0.32; 95% CI = [- 0.60, - 0.03]) linear regressions and less absolute presenteeism (15.42, 95% CI = [0.87, 29.98]) in the weighted unadjusted analysis. CONCLUSION: The reflexology intervention delivered by lay caregivers reduced hospital visits and increased workplace productivity in a short-term period, which has potential for cost saving for health care systems and employers. TRIAL REGISTRATION: NCT01582971.

Self-Management Through Social Support Among Emerging Adults With Inflammatory Bowel Disease.

BACKGROUND: Emerging adulthood is a unique developmental stage, which may affect individuals' self-management behaviors, social support, and the relationship between these two constructs. Among older adults, social support has been shown to improve self-management behaviors for individuals with chronic conditions; however, this relationship has not been examined with emerging adults (age 18-29 years) who have inflammatory bowel disease (IBD). OBJECTIVES: The aim of the study was to examine the relationship between two conceptualizations of social support (received and perceived availability of social support) and IBD-related self-management behaviors among emerging adults with IBD. METHODS: A convenience sample of emerging adult IBD individuals (currently prescribed medication to manage IBD) were recruited through ResearchMatch, Facebook, and word of mouth. The study was guided by key elements of the individual and family self-management theory. Participants responded to demographic and condition-specific questionnaires: the Inventory of Dimensions of Emerging Adulthood, the Inventory of Socially Supportive Behaviors, the Medical Outcomes: Social Support Survey, the Medication Adherence Report Scale, and the Dietary Screener Questionnaire. RESULTS: Emerging adults with high received informational support reported greater medication adherence compared to those with low received informational support when controlling for biological medications, time since diagnosis, symptom frequency, and feeling in-between adolescence and adulthood. Neither type of social support was associated with diet modification. DISCUSSION: Received informational social support, medication type, time since diagnosis, symptoms, and emerging adulthood factors have the potential to influence medication adherence. Received informational social support interventions, such as patient-to-patient or group-based mentoring, may serve to improve medication adherence among emerging adults with IBD.

Systematic Review of Social Support on Psychological Symptoms and Self-Management Behaviors Among Adults With Inflammatory Bowel Disease.

PURPOSE: The purpose was to determine the relationship between social support, psychological symptoms and self-management behaviors among adults with inflammatory bowel disease (IBD) and examine the influence of types of social support and patient age. DESIGN: This was a systematic review. PubMed, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Communication and Mass Media Complete, and Communication Abstracts were searched. Publication dates were limited to January 2000 to August 2018. METHODS: The systematic review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement, and quality was appraised based on the Critical Appraisal Skills Programme for cohort studies tool. The data were synthesized using narrative synthesis techniques. FINDINGS: The literature review yielded 458 results. Eight articles met inclusion criteria. Articles utilized a variety of conceptualizations of both social support and self-management behaviors, making comparisons difficult. Findings demonstrated an inverse relationship between social support and psychological symptoms, and in one study only when social support buffered high stress. Studies with significant relationships between age and self-management behaviors indicated that a lower age was associated with decreased self-management behaviors. CONCLUSIONS: Social support has the potential to influence psychological symptoms among patients with IBD. Future research should examine types of social support (i.e., emotional, informational, and tangible support) and measure levels of received social support. CLINICAL RELEVANCE: Social support may serve as a modifiable factor to improve psychological symptoms among adults with IBD. Younger adults (age <40 years) may benefit from specialized interventions to address self-management behaviors.

Symptomatic and Functional Recovery From Major Depressive Disorder in the Ibadan Study of Ageing.

OBJECTIVES: Very little is known about the association between symptomatic and functional recovery from late-life major depressive disorder (MDD) in sub-Saharan Africa. We investigated factors associated with sustained symptomatic remission (SR) from MDD and the 5-year trajectory of post-MDD physical functioning. DESIGN: 5-year prospective study with three follow-up waves in 2007, 2008, and 2009. SETTING/PARTICIPANTS: Household multistage probability sample of 2,149 Nigerians who were aged 65 years or older. MEASUREMENTS: Activities of Daily Living (ADL) and MDD were assessed using the Kadz index and Composite International Diagnostic Interview, respectively. We studied those with current MDD (prevalent in 2003-2004 or incident in 2007), and who achieved SR in subsequent waves compared with a chronic/recurrent course (CR). RESULTS: Baseline demographic characteristics, health, and lifestyle factors were not associated with SR in logistic regression analyses. In mixed-effect linear regression models adjusting for age, sex, and socioeconomic status, ADL worsened in SR (ß = 1.0, 95% CI: 0.2, 1.8), but more so in CR (ß = 2.3, 95% CI: 1.6, 3.0). Poorer ADL at follow-up was predicted by age (ß = 2.9, 95% CI: 1.8, 4.0) and economic status (ß = 1.4, 95% CI: 0.3, 2.4). CONCLUSIONS: There was a deteriorating course of disability despite symptomatic recovery from late-life MDD in this sample. This finding has implications for policy and guidelines for the management of late-life depression and disability.

Maternal Socioeconomic Mobility and Preterm Delivery: A Latent Class Analysis.

Objective Growing evidence suggests that maternal socioeconomic mobility (SM) is associated with pregnancy outcomes. Our study investigated the association between maternal SM from childhood to adulthood and the risk of preterm delivery (PTD), and examined heterogeneity of associations by race/ethnicity. Methods In this study, 3019 pregnant women enrolled from 5 Michigan communities at 16-27 weeks' gestation (1998-2004) provided their parents' socioeconomic position (SEP) indicators (education, occupation, receipt of public assistance) and their own and child's father's SEP indicators (education, occupation, Medicaid status, and household income) at the time of enrollment. Latent class analysis was used to identify latent classes of childhood SEP indicators, adulthood SEP indicators, and SM from childhood to adulthood, respectively. A model-based approach to latent class analysis with distal outcome assessed relations between latent class and PTD, overall and within race/ethnicity groups. Results Three latent classes (low, middle, high) were identified for childhood SEP indicators and adulthood SEP indicators, respectively; while four latent classes (static low, upward, downward, and static high) best described SM. Women with upward SM had decreased odds of PTD (Odds ratio = 0.60, 95% confidence interval: 0.42, 0.87), compared to those with static low SEP. This SM advantage was true for all women and most pronounced in white/others women. Conclusions Maternal experiences of upward SM may be important considerations when assessing PTD risk. Our results support the argument that policies and programs aimed at improving women's SEP could lower PTD rates.

Economic Conditions During Pregnancy and Adverse Birth Outcomes Among Singleton Live Births in the United States, 1990-2013.

We know little about the relationship between the macroeconomy and birth outcomes, in part due to the methodological challenge of distinguishing effects of economic conditions on fetal health from effects of economic conditions on selection into live birth. We examined associations between state-level unemployment rates in the first 2 trimesters of pregnancy and adverse birth outcomes, using natality data on singleton live births in the United States during 1990-2013. We used fixed-effect logistic regression models and accounted for selection by adjusting for state-level unemployment before conception and maternal characteristics associated with both selection and birth outcomes. We also tested whether associations between macroeconomic conditions and birth outcomes differed during and after (compared with before) the Great Recession (2007-2009). Each 1-percentage-point increase in the first-trimester unemployment rate was associated with a 5% increase in odds of preterm birth, while second-trimester unemployment was associated with a 3% decrease in preterm birth odds. During the Great Recession, however, first-trimester unemployment was associated with a 16% increase in odds of preterm birth. These findings increase our understanding of the effects of the Great Recession on health and add to growing literature suggesting that macro-level social and economic factors contribute to perinatal health.

A Comparison of Health Plan- and Provider-Delivered Chronic Care Management Models on Patient Clinical Outcomes.

BACKGROUND: The real world implementation of chronic care management model varies greatly. One aspect of this variation is the delivery mode. Two contrasting strategies include provider-delivered care management (PDCM) and health plan-delivered care management (HPDCM). OBJECTIVE: We aimed to compare the effectiveness of PDCM vs. HPDCM on improving clinical outcomes for patients with chronic diseases. DESIGN: We used a quasi-experimental two-group pre-post design using the difference-in-differences method. PATIENTS: Commercially insured patients, with any of the five chronic diseases-congestive heart failure, chronic obstructive pulmonary disease, coronary heart disease, diabetes, or asthma, who were outreached to and engaged in either PDCM or HPDCM were included in the study. MAIN MEASURES: Outreached patients were those who received an attempted or actual contact for enrollment in care management; and engaged patients were those who had one or more care management sessions/encounters with a care manager. Effectiveness measures included blood pressure, low density lipoprotein (LDL), weight loss, and hemoglobin A1c (for diabetic patients only). Primary endpoints were evaluated in the first year of follow-up. KEY RESULTS: A total of 4,000 patients were clustered in 165 practices (31 in PDCM and 134 in HPDCM). The PDCM approach demonstrated a statistically significant improvement in the proportion of outreached patients whose LDL was under control: the proportion of patients with LDL < 100 mg/dL increased by 3 % for the PDCM group (95 % CI: 1 % to 6 %) and 1 % for the HPDCM group (95 % CI: -2 % to 5 %). However, the 2 % difference in these improvements was not statistically significant (95 % CI: -2 % to 6 %). The HPDCM approach showed 3 % [95 % CI: 2 % to 6 %] improvement in overall diabetes care among outreached patients and significant reduction in obesity rates compared to PDCM (4 %, 95 % CI: 0.3 % to 8 %). CONCLUSIONS: Both care management delivery modes may be viable options for improving care for patients with chronic diseases. In this commercially insured population, neither PDCM nor HPDCM resulted in substantial improvement in patients' clinical indicators in the first year. Different care management strategies within the provider-delivered programs need further investigation.

Implementing shared decision making in federally qualified health centers, a quasi-experimental design study: the Office-Guidelines Applied to Practice (Office-GAP) program.

BACKGROUND: Use of Shared Decision-Making (SDM) and Decision Aids (DAs) has been encouraged but is not regularly implemented in primary care. The Office-Guidelines Applied to Practice (Office-GAP) intervention is an application of a previous model revised to address guidelines based care for low-income populations with diabetes and coronary heart disease (CHD). OBJECTIVE: To evaluate Office-GAP Program feasibility and preliminary efficacy on medication use, patient satisfaction with physician communication and confidence in decision in low-income population with diabetes and coronary heart disease (CHD) in a Federally Qualified Healthcare Center (FQHC). METHOD: Ninety-five patients participated in an Office-GAP program. A quasi-experimental design study, over 6 months with 12-month follow-up. Office-GAP program integrates health literacy, communication skills education for patients and physicians, patient/physician decision support tools and SDM into routine care. MAIN MEASURES: 1) Implementation rates of planned program elements 2) Patient satisfaction with communication and confidence in decision, and 3) Medication prescription rates. We used the GEE method for hierarchical logistic models, controlling for confounding. RESULTS: Feasibility of the Office-GAP program in the FQHC setting was established. We found significant increase in use of Aspirin/Plavix, statin and beta-blocker during follow-up compared to baseline: Aspirin OR 1.5 (95 % CI: 1.1, 2.2) at 3-months, 1.9 (1.3, 2.9) at 6-months, and 1.8 (1.2, 2.8) at 12-months. Statin OR 1.1 (1.0, 1.3) at 3-months and 1.5 (1.1, 2.2) at 12-months; beta-blocker 1.8 (1.1, 2.9) at 6-months and 12-months. Program elements were consistently used (≥ 98 % clinic attendance at training and tool used). Patient satisfaction with communication and confidence in decision increased. CONCLUSIONS: The use of Office-GAP program to teach SDM and use of DAs in real time was demonstrated to be feasible in FQHCs. It has the potential to improve satisfaction with physician communication and confidence in decisions and to improve medication use. The Office-GAP program is a brief, efficient platform for delivering patient and provider education in SDM and could serve as a model for implementing guideline based care for all chronic diseases in outpatient clinical settings. Further evaluation is needed to establish feasibility outside clinical study, reach, effectiveness and cost-effectiveness of this approach.
