Interdisciplinary team-based care for patients with chronic pain on long-term opioid treatment in primary care (PPACT) - Protocol for a pragmatic cluster randomized trial

BACKGROUND

Chronic pain is one of the most common, disabling, and expensive public health problems in the United States. Interdisciplinary pain management treatments that employ behavioral approaches have been successful in helping patients with chronic pain reduce symptoms and regain functioning. However, most patients lack access to such treatments. We are conducting a pragmatic clinical trial to test the hypothesis that patients who receive an interdisciplinary biopsychosocial intervention, the Pain Program for Active Coping and Training (PPACT), at their primary care clinic will have a greater reduction in pain impact in the year following than patients receiving usual care.

METHODS/DESIGN

This is an effectiveness-implementation hybrid pragmatic clinical trial in which we randomize clusters of primary care providers and their patients with chronic pain who are on long-term opioid therapy to 1) receive an interdisciplinary behavioral intervention in conjunction with their current health care or 2) continue with current health care services. Our primary outcome is pain impact (a composite of pain intensity and pain-related interference) measured using the PEG, a validated three-item assessment. Secondary outcomes include pain-related disability, patient satisfaction, opioids dispensed and health care utilization. An economic evaluation assesses the resources and costs necessary to deliver the intervention and its cost-effectiveness compared with usual care. A formative evaluation employs mixed methods to understand the context for implementation in the participating health care systems.

DISCUSSION

This trial will inform the feasibility of implementing interdisciplinary behavioral approaches to pain management in the primary care setting, potentially providing a more effective, safer, and more satisfactory alternative to opioid-based chronic pain treatment.

Participatory Research to Advance Colon Cancer Prevention (PROMPT): Study protocol for a pragmatic trial

BACKGROUND

Colon cancer is the second leading cause of cancer deaths in the United States. The Participatory Research to Advance Colon Cancer Prevention (PROMPT) study is a collaboration between two research institutions and a federally qualified health center (FQHC). The study seeks to raise colon cancer screening rates using a direct-mail fecal immunochemical testing (FIT) and reminder program in an FQHC serving a predominantly Latino population in California.

METHODS

PROMPT is a pragmatic trial enrolling 16 clinics. The study will test automated and live prompts (i.e., alerts, reminders) to a direct-mail FIT program in two phases. In Phase I, we tailored and defined intervention components for the pilot using a community-based participatory research approach called boot camp translation. We then plan to conduct a three-arm patient-randomized comparative effectiveness trial in two pilot clinics to compare 1) automated prompts, 2) live prompts, and 3) a combination of automated plus live prompts to alert and remind patients to complete screening. In Phase II, the adapted best practice intervention will be spread to additional clinics within the FQHC (estimated population 27,000) and assessed for effectiveness. Patient and staff interviews will be conducted to explore receptivity to the program and identify barriers to implementation.

DISCUSSION

This pragmatic trial applies innovative approaches to engage diverse stakeholders and will test the effectiveness and spread of a direct-mail plus reminder program. If successful, the program will provide a model for a cost-effective method to raise colon cancer screening rates among Latino patients receiving care in FQHCs.

Longitudinal Impact of a Randomized Clinical Trial to Improve Family Function, Reduce Maternal Stress and Improve Child Outcomes in Families of Children with ADHD

Objective Evaluate the efficacy of a 12 month nursing case-management intervention over a period of 18 months, 6 months after the end of intervention, for families of children attention deficit hyperactivity disorder (ADHD). Methods Mother and child dyads were enrolled to participate in a randomized controlled clinical trial. Children were 4-18 years old. Data were collected at baseline, 6, 12, and 18 months or 6 months after the termination of direct intervention. Longitudinal analyses, using generalized estimating equations, were conducted to assess change in study outcomes relating to family function, maternal stress, and child behavior over the 18 month period. Results Compared to control families, some family function outcomes were moderately improved in the intervention group. In particular, intervention families demonstrated substantial improvement in implementing family behavior controls (p value = 0.038) and improvement in family satisfaction (not statistically significant p = 0.062). Although there was improvement in the overall family function measure there was not a statistically significant difference between groups. Maternal stress and child behavior outcomes were not significantly different between control and intervention groups by the end of the intervention. Conclusions for Practice Addressing ADHD is complex and requires the assessment of comorbidities that might exacerbate negative behavior. Our findings support the latest American Academy of Pediatrics guidelines to use behavioral therapy as the first line of treatment in young children. Nursing case-management interventions that provide direct family education and improve family function, especially with respect to providing structure and behavior control, may complement and facilitate behavioral therapy for treatment of ADHD and improving child behavior.

Abstract P3-08-05: Validation of a nomogram for predicting recurrence among women with ductal carcinoma in situ and breast conserving surgery in an integrated health care system

Current management of ductal carcinoma in situ (DCIS) most often entails removing the lesion by breast-conserving surgery. Quantifying the risk of a patient's ipsilateral breast event (IBE) recurrence, either invasive cancer or DCIS, after breast conserving surgery remains a clinical concern. The aim of this study was to validate the Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram to predict IBE recurrence in patients from our institution.

Patients and Methods

We retrospectively identified 608 patients in the Kaiser Permanente Northwest integrated healthcare system with a diagnosis of DCIS who had undergone local excision from 1990 through 2007. We assessed the performance of the MSKCC nomogram for predicting IBE recurrence using measures of discrimination (how well risk scores separate those with and without the event) and calibration (agreement between predicted and observed risk). We calculated Harrell's C and R2D to provide estimates of discrimination. We calculated the calibration slope by performing a Cox regression using the prognostic index (PI; predicted log relative hazard based on the original Cox coefficients), with a slope not significantly different from 1 indicating no difference in discrimination from the development sample. We also examined discrimination by comparing the KM curves of 4 risk groups and in a Cox regression as a predictor, which were created using Cox's method (4 groups using the 16th, 50th, & 84th percentiles), as no risk groups were defined in the MSKCC development study. We examined whether there was model misfit by testing each predictor in a Cox regression with an offset of the PI. Finally, we assessed calibration by plotting the observed rates and associated 95% CIs against the predicted probabilities for groups based on 4 risk groups and octiles.

Results

The median follow-up time for the KPNW cohort was 125 months. The 10-year IBE recurrence rate was 9.5%, 95% CI [7.0%, 13.0%). Harrell's C was .70, which is comparable to what has been found in other validation studies. The PI accounted for 22% of variation in time (R2D =.22, 95% CI [.08, .38]). The test of the calibration slope provided no support that discrimination in this sample differs from the development study (LR χ2(1)=0.21, p=.65). An examination of the Kaplan-Meier curves among the risk groups showed good separation of the high risk group compared to the others, but little separation between the lowest two risk groups. None of the predictors demonstrated evidence for differential weighting from the MSKCC coefficients (p values ranged from .08 to .97). Calibration was good for the lowest, low, and moderate risk groups, but there was underprediction in the high risk group. When examining calibration using octiles, we found a similar pattern to that of other validation studies in which the highest octile had the furthest departure from perfect agreement.

Conclusion

The MSKCC nomogram for predicting IBE recurrence in patients with DCIS who were treated with local excision have some utility, and our results are consistent with other validation efforts. However, there is much potential to further increase the prediction of recurrence beyond what is possible with the MSKCC nomogram.

Cost-effectiveness of Cognitive Behavioral Therapy for Depressed Youth Declining Antidepressants

BACKGROUND AND OBJECTIVES

Adolescents with depression identified in primary care settings often have limited treatment options beyond antidepressant (AD) therapy. We assessed the cost-effectiveness of a brief cognitive behavioral therapy (CBT) program among depressed adolescents who declined or quickly stopped using ADs.

METHODS

A total of 212 youth with depression were randomly assigned to treatment as usual (TAU) or TAU plus brief individual CBT. Clinical outcomes included depression-free days (DFDs) and estimated quality-adjusted life-years (QALYs). Costs were adjusted to 2008 US dollars. Incremental cost-effectiveness ratios (ICERs) comparing CBT to TAU were calculated over 12- and 24-month follow-up periods.

RESULTS

Youth randomly assigned to CBT had 26.8 more DFDs (P = .044) and 0.067 more QALYs (P = .044) on average compared with TAU over 12 months. Total costs were $4976 less (P = .025) by the end of the 24-month follow-up among youth randomly assigned to CBT. Total costs per DFD were -$51 (ICER = -$51; 95% confidence interval [CI]: -$394 to $9) at 12 months and -$115 (ICER = -$115; 95% CI: -$1090 to -$6) at 24 months. Total costs per QALY were -$20 282 (ICER = -$20 282; 95% CI: -$156 741 to $3617) at 12 months and -$45 792 (ICER = -$45 792; 95% CI: -$440 991 to -$2731) at 24 months.

CONCLUSIONS

Brief primary care CBT among youth declining AD therapy is cost-effective by widely accepted standards in depression treatment. CBT becomes dominant over TAU over time, as revealed by a statistically significant cost offset at the end of the 2-year follow-up.

Medication-assisted treatment for substance use disorders within a national community health center research network

BACKGROUND

The Affordable Care Act increases access to treatment services for people who suffer from substance use disorders (SUDs), including alcohol use disorders (AUDs) and opioid use disorders (OUDs). This increased access to treatment has broad implications for delivering health services and creates a dramatic need for transformation in clinical care, service lines, and collaborative care models. Medication-assisted treatments (MAT) are effective for helping SUD patients reach better outcomes. This article uses electronic health record (EHR) data to examine the prevalence of EHR-documented SUDs, patient characteristics, and patterns of MAT prescribing and screening for patients within the Community Health Applied Research Network (CHARN), a national network of 17 community health centers that facilitates patient-centered outcomes research among underserved populations.

METHODS

Hierarchical generalized linear models examined patient characteristics, SUD occurrence rates, MAT prescription, and human immunodeficiency virus (HIV) and hepatitis virus C screening for patients with AUDs or OUDs. Results: Among 572,582 CHARN adult patients, 16,947 (3.0%) had a documented AUD diagnosis and 6,080 (1.1%) an OUD diagnosis. Alcohol MAT prescriptions were documented for 547 AUD patients (3.2%) and opioid MAT for 1,764 OUD patients (29.0%). Among OUD patients, opioid MAT was significantly associated with HIV screening (odds ratio [OR] = 1.31, P < .001) in OUD patients, as was alcohol MAT among AUD patients (OR = 1.30, P = .013).

CONCLUSIONS

These findings suggest that effective opioid and alcohol MAT may be substantially underprescribed among safety-net patients identified as having OUDs or AUDs.

Dental provider practices and perceptions regarding adolescent vaccination

OBJECTIVE

To assess dental providers' clinical practices and perceptions regarding adolescent vaccinations.

METHODS

We surveyed 234 dental providers in an integrated health care setting in Portland, Oregon, in March-April 2015. We assessed participants' knowledge of adolescent vaccines, barriers to recommending vaccines, and their perceived role in the promotion of vaccination and preventive medical care.

RESULTS

Over 80 percent of respondents correctly identified influenza, tetanus-diphtheria-acellular pertussis, and human papillomavirus as vaccinations recommended for adolescents; 60 percent correctly identified meningococcal conjugate. Forty-four percent of providers reported previously discussing vaccination with their adolescent patients. Lack of knowledge (66 percent), uncertainty about whether patients would accept recommendations (62 percent), and lack of time (61 percent) were commonly reported barriers. While few providers expressed personal concerns about the safety (13 percent) and effectiveness (10 percent) of adolescent vaccines, most believed parents had concerns about safety (70 percent) and effectiveness (60 percent). Although 80 percent endorsed the premise that providers should discuss preventive medical care with their patients, only 54 percent said they should discuss vaccinations specifically.

CONCLUSIONS

Dental providers reported several barriers to recommending vaccines. While comfortable with discussing preventive medical care in general, providers are less comfortable making vaccine recommendations to their patients. Vaccine recommendations are not a traditional practice among dental providers and may require additional education and communication tools.

Implications of American College of Cardiology/American Heart Association (ACC/AHA) Cholesterol Guidelines on Statin Underutilization for Prevention of Cardiovascular Disease in Diabetes Mellitus Among Several US Networks of Community Health Centers

Background

Little is known about statin underutilization among diabetes mellitus patients cared for in community health centers, which tend to serve socioeconomically disadvantaged populations. Implications of the American College of Cardiology/American Heart Association (ACC/AHA) guidelines on preexisting gaps in statin treatment in this population are unclear.

Methods and Results

We included 32 440 adults (45% male, 63% nonwhite, 29% uninsured/Medicaid) aged 40 to 75 years with diabetes mellitus who received care within 16 community health center groups in 11 states in the Community Health Applied Research Network during 2013. Statin prescribing was analyzed as a function of concordance with the National Cholesterol Education Program Adult Treatment Panel 2001 and ACC/AHA 2013 guidelines. More patients’ treatments were concordant with the ACC/AHA (52.8%) versus the National Cholesterol Education Program Adult Treatment Panel (36.2%) guideline. Female sex was associated with lower concordance for both (odds ratio [OR] 0.90, CI 0.85‐0.94; and OR 0.84, CI 0.80‐0.88, respectively). Being insured, an Asian/Pacific Islander, or primarily Spanish speaking were associated with greater concordance for both guidelines: 35.5% (11 526/32 440) were concordant with neither guideline, the majority (79.7%) having no statin prescribed; 28.2% (9168/32 440) were concordant with ACC/AHA but not the National Cholesterol Education Program Adult Treatment Panel. 8.7% of these patients had a low‐density lipoprotein cholesterol >160 mg/dL despite having a moderate‐ or high‐intensity statin prescribed. And 11.6% (3772/32 440) were concordant with the National Cholesterol Education Program Adult Treatment Panel but not with ACC/AHA. Most of these patients had a low‐density lipoprotein cholesterol between 70 and 99 mg/dL with no or a low‐intensity statin prescribed.

Conclusions

Opportunities exist to improve cholesterol management in diabetes mellitus patients in community health centers. Addressing care gaps could improve cardiovascular disease prevention in this high‐risk population.

The NextGen Study: patient motivation for participation in genome sequencing for carrier status

Background

While translational genomic sequencing research is increasing, few studies have been limited to healthy individuals; most have focused on patients with a disease or a strong family history of a disorder. The limited studies that have included healthy individuals have focused on the disclosure of medically actionable secondary results, rather than carrier status, to assess reproductive risks. To address this important gap, we conducted the NextGen study, which focuses on carrier status and medically actionable secondary findings in a population of women planning a pregnancy.

Methods

We assessed 310 participants’ motivations for receiving genome sequencing for expanded carrier screening and experiences with familial genetic conditions that may relate to study participation.

Results

Most participants reported that obtaining general health information from genome sequencing was their primary motivator, even though they were recruited to join a study to learn more about carrier status. Forty‐two percent of enrolled women became pregnant prior to obtaining sequencing results.

Conclusion

Genomic carrier testing may need to be offered to women prior to active pregnancy efforts to be useful for reproductive planning.

Predictors of urinary diversion choice in patients with bladder cancer in integrated care settings

4543

Background: Annually over 10,000 people with bladder cancer in the US have cystectomy surgery with urinary diversion (UD). While ileal conduit (IC) is most common, neobladder (NB) and continent pouch (CP) are options to retain urinary continence. Few studies in community settings have examined patient and clinician factors associated with UD choice. Methods: Eligible patients were age ≥21 with a cystectomy and UD for bladder cancer from 1/2010 to 6/2015 in 3 West coast Kaiser Permanente regions. Data were obtained from the EHR and chart review.We useda mixed effects logistic regression model with surgeon as a random effect, and region as a fixed effect, to identify patient factors associated with UD choice (IC vs NB/CP). We also examined whether surgeon factors were associated with UD choice above and beyond patient factors. Results: Among 1063 patients, 80% had an IC. IC patients were older (mean age 72 vs. 62), more likely female (24% vs. 16%), more likely diagnosed with AJCC stage III/IV (41% vs. 28%), and had higher Charlson comorbidity score (median 4 vs. 3) than NB/CP patients. Surgeons accounted for a sizable portion of the variability in UD choice (ICC = .26). The model with patient factors showed good fit (AUC = .93, Hosmer-Lemeshow test p = .22). Including surgeon factors (annual cystectomy volume, specialty training, clinical tenure) did not improve model fit (p = .32). Female sex, eGFR < 45, 4+ comorbidities, and stage III/IV tumors were associated with higher odds of receiving an IC vs. NB/CP (Table). Conclusions: Patient factors predict much of the variability in UD choice. The high ICC indicates that surgeons also contribute to this process, but surgeon factors we examined were not uniquely associated with IC. Future studies should explore more nuanced surgeon factors, such as how UD choice is shaped by personal beliefs about UD and likely outcomes. [Table: see text]

Decision dissonance/alignment scale to promote patient-centered decisions about urinary diversion with cystectomy for bladder cancer

e16010

Background: The choice of urinary diversion (UD) with cystectomy is an opportunity to provide preference-driven care. We adapted a decision dissonance scale to measure concordance of patient goals with choice of ileal conduit (IC) vs. neobladder (NB) UD. Methods: With patient and clinician input, we identified 6 IC- and 4 NB-aligned goals, each rated on an 11-point scale (0 = not at all important to 10 = very important). Kaiser Permanente members rated the importance of these goals in a comprehensive survey mailed 6 months post-op (71% response rate (269/381)). Excluding respondents (n=93) with contraindications to NB and missing data on goals, we examined structural validity with principal axis factor analysis and convergent validity using correlations with other decision-making measures. Results: Items aligned to IC vs. NB factored separately as hypothesized (Table 1). NB patients prioritized (p<.05) NB-aligned goals (M=8.8, SD=1.8) over NB-dissonant goals (M=4.3, SD=2.4). IC patients’ alignment (M=5.4, SD=2.7) and dissonance (M=5.6, SD=2.1) ratings were similar. Dissonance was negatively correlated with informed decision-making (r=-.27) and satisfaction with care (r=-.21), and positively correlated with decision regret (r=.28) (each p<.01), but not correlated with shared decision making or decision style preference. Alignment was not significantly correlated with decision-making measures. Conclusions: Our measure distinguished patient values that could guide shared decision-making about UD choice. Patients who chose a NB had strong preferences for maintaining body integrity and function. [Table: see text]

Design of a randomized controlled trial for genomic carrier screening in healthy patients seeking preconception genetic testing

Population-based carrier screening is limited to well-studied or high-impact genetic conditions for which the benefits may outweigh the associated harms and costs. As the cost of genome sequencing declines and availability increases, the balance of risks and benefits may change for a much larger number of genetic conditions, including medically actionable additional findings. We designed an RCT to evaluate genomic clinical sequencing for women and partners considering a pregnancy. All results are placed into the medical record for use by healthcare providers. Through quantitative and qualitative measures, including baseline and post result disclosure surveys, post result disclosure interviews, 1-2year follow-up interviews, and team journaling, we are obtaining data about the clinical and personal utility of genomic carrier screening in this population. Key outcomes include the number of reportable carrier and additional findings, and the comparative cost, utilization, and psychosocial impacts of usual care vs. genomic carrier screening. As the study progresses, we will compare the costs of genome sequencing and usual care as well as the cost of screening, pattern of use of genetic or mental health counseling services, number of outpatient visits, and total healthcare costs. This project includes novel investigation into human reactions and responses from would-be parents who are learning information that could both affect a future pregnancy and their own health.

Generating a taxonomy for genetic conditions relevant to reproductive planning

As genome or exome sequencing (hereafter genome-scale sequencing) becomes more integrated into standard care, carrier testing is an important possible application. Carrier testing using genome-scale sequencing can identify a large number of conditions, but choosing which conditions/genes to evaluate as well as which results to disclose can be complicated. Carrier testing generally occurs in the context of reproductive decision-making and involves patient values in a way that other types of genetic testing may not. The Kaiser Permanente Clinical Sequencing Exploratory Research program is conducting a randomized clinical trial of preconception carrier testing that allows participants to select their preferences for results from among broad descriptive categories rather than selecting individual conditions. This paper describes (1) the criteria developed by the research team, the return of results committee (RORC), and stakeholders for defining the categories; (2) the process of refining the categories based on input from patient focus groups and validation through a patient survey; and (3) how the RORC then assigned specific gene-condition pairs to taxonomy categories being piloted in the trial. The development of four categories (serious, moderate/mild, unpredictable, late onset) for sharing results allows patients to select results based on their values without separately deciding their interest in knowing their carrier status for hundreds of conditions. A fifth category, lifespan limiting, was always shared. The lessons learned may be applicable in other results disclosure situations, such as incidental findings.

One-year postpartum outcomes following a weight management intervention in pregnant women with obesity

OBJECTIVE

This analysis was focused on 1-year maternal and infant follow-up of a randomized trial that tested a weight management intervention conducted during pregnancy.

METHODS

One hundred fourteen women with obesity (mean BMI 36.7 kg/m(2) ) were randomly assigned at a mean of 15 weeks gestation to a weight management intervention or usual care control condition. The intervention ended at delivery and resulted in less gestational weight gain and a lower proportion of large-for-gestational-age newborns among intervention compared with control participants. The primary outcome at 12 months postpartum was maternal weight. Secondary outcomes included infant weight-for-age and weight-for-length z-scores.

RESULTS

At 1 year, mothers in the intervention group weighed 96.3 ± 18.6 kg and those in the control group 99.7 ± 19.2 kg. There was no significant difference between groups in change in weight from randomization to 1 year postpartum (b = -0.47, 95% CI: -4.03 to 3.08). There was a significant main effect of group for infant weight-for-age z-scores (b = -0.40, 95% CI: -0.75 to -0.05) but not infant weight-for-length z-scores (b = -0.20, 95% CI: -0.59 to 0.20).

CONCLUSIONS

A gestational weight management intervention did not influence maternal weight or infant weight-for-length at 1 year postpartum. Future studies may be warranted to determine whether extending prenatal interventions into the postpartum period would be beneficial for maternal and infant outcomes.

Referring Hospitalized Smokers to Outpatient Quit Services: A Randomized Trial

INTRODUCTION

Linking outpatient cessation services to bedside counseling for hospitalized smokers can improve long-run quit rates. Adding an assisted referral (AR) offer to a tobacco treatment specialist consult service fits the team approach to care in U.S. hospitals.

DESIGN

A two-arm patient-randomized trial tested the effectiveness of adding an AR offer to outpatient smoking-cessation services and interactive voice recognition (AR+IVR) follow-up to a usual care (UC) tobacco-cessation consult for hospitalized smokers.

SETTING/PARTICIPANTS

Over 24 months (November 2011-November 2013), 898 hospitalized adult smokers interested in quitting smoking were recruited from three large hospitals in the Portland, Oregon, area: an integrated group model HMO (n=622), a community hospital (n=195), and an academic health center (n=81).

INTERVENTION

Tobacco treatment specialists identified smokers and provided an intensive bedside tobacco use assessment and cessation consultation (UC). AR+IVR recipients also received proactive ARs to available outpatient counseling programs and medications, and linked patients to a tailored IVR telephone follow-up system.

MAIN OUTCOME MEASURES

The primary outcome was self-reported 30-day abstinence at 6-month follow-up. Secondary outcomes included self-reported and continuous abstinence and biochemically confirmed 7-day abstinence at 6 months. Follow-up was completed in September 2014; data were analyzed in 2015.

RESULTS

A total of 597 and 301 hospitalized smokers were randomized to AR+IVR and UC, respectively. AR+IVR and UC recipients received 19.3 and 17.0 minutes of bedside counseling (p=0.372), respectively. Most (58%) AR+IVR patients accepted referrals for counseling, 43% accepted medications, and 28% accepted both. Self-reported 30-day abstinence for AR+IVR (17.9%) and UC (17.3%) were not statistically significant (p=0.569). Differences in 7-day, continuous, and biochemically confirmed abstinence by treatment group also were insignificant, overall and adjusting for site.

CONCLUSIONS

Adding an AR to outpatient counseling and medications did not increase cigarette abstinence at 6 months compared to UC alone.

Modeling ADHD Child and Family Relationships

Little information is available on how to help families manage common negative sequelae of attention deficit/hyperactivity disorder (ADHD). This article is a report of the extent to which a theoretical formulation of child behavior, maternal distress, and family conflict was explained by data obtained from a community sample of families with children and adolescents with ADHD. Structural equation modeling was used to test the theoretical model. The primary variables of interest were (a) child behavior problems, (b) maternal distress, and (c) family conflict. The results suggest that maternal distress may mediate the relationship between child behavior problems and family conflict, indicating the critical importance of mothers in ADHD families and the need to provide them with additional support.

Performance of ACMG-AMP Variant-Interpretation Guidelines among Nine Laboratories in the Clinical Sequencing Exploratory Research Consortium

Evaluating the pathogenicity of a variant is challenging given the plethora of types of genetic evidence that laboratories consider. Deciding how to weigh each type of evidence is difficult, and standards have been needed. In 2015, the American College of Medical Genetics and Genomics (ACMG) and the Association for Molecular Pathology (AMP) published guidelines for the assessment of variants in genes associated with Mendelian diseases. Nine molecular diagnostic laboratories involved in the Clinical Sequencing Exploratory Research (CSER) consortium piloted these guidelines on 99 variants spanning all categories (pathogenic, likely pathogenic, uncertain significance, likely benign, and benign). Nine variants were distributed to all laboratories, and the remaining 90 were evaluated by three laboratories. The laboratories classified each variant by using both the laboratory's own method and the ACMG-AMP criteria. The agreement between the two methods used within laboratories was high (K-alpha = 0.91) with 79% concordance. However, there was only 34% concordance for either classification system across laboratories. After consensus discussions and detailed review of the ACMG-AMP criteria, concordance increased to 71%. Causes of initial discordance in ACMG-AMP classifications were identified, and recommendations on clarification and increased specification of the ACMG-AMP criteria were made. In summary, although an initial pilot of the ACMG-AMP guidelines did not lead to increased concordance in variant interpretation, comparing variant interpretations to identify differences and having a common framework to facilitate resolution of those differences were beneficial for improving agreement, allowing iterative movement toward increased reporting consistency for variants in genes associated with monogenic disease.

Cognitive Behavioral Therapy in Primary Care for Youth Declining Antidepressants: A Randomized Trial

BACKGROUND AND OBJECTIVE

Health care providers have few alternatives for youth depression other than antidepressants. We examined whether brief cognitive behavioral therapy (CBT) is a viable alternative in primary care.

METHODS

A total of 212 adolescents aged 12 to 18 with major depression who had recently declined or quickly discontinued new antidepressant treatment were randomized to self-selected treatment as usual (TAU) control condition or TAU plus brief individual CBT. Blinded evaluators followed youth for 2 years. The primary outcome was time to major depression diagnostic recovery.

RESULTS

CBT was superior to the control condition on the primary outcome of time to diagnostic recovery from major depression, with number needed to treat from 4 to 10 across follow-up. A similar CBT advantage was found for time to depression diagnosis response, with number needed to treat of 5 to 50 across time points. We observed a significant advantage for CBT on many secondary outcomes over the first year of follow-up but not the second year. Cohen's d effect sizes for significant continuous measures ranged from 0.28 to 0.44, in the small to medium effect range. Most TAU health care services did not differ across conditions, except for psychiatric hospitalizations, which occurred at a significantly higher rate in the control condition through the first year of follow-up.

CONCLUSIONS

Observed results were consistent with recent meta-analyses of CBT for youth depression. The initial year of CBT superiority imparted an important clinical benefit and may reduce the risk of future recurrent depression episodes.

Improvement in Body Image, Perceived Health, and Health-Related Self-Efficacy Among People With Serious Mental Illness: The STRIDE Study

OBJECTIVE

The authors examined secondary outcomes of STRIDE, a randomized controlled trial that tested a weight-loss and lifestyle intervention for individuals taking antipsychotic medications.

METHODS

Hierarchical linear regression was used to explore the effects of the intervention and weight change at follow-up (six, 12, and 24 months) on body image, perceived health, and health-related self-efficacy.

RESULTS

Participants were 200 adults who were overweight and taking antipsychotic agents. Weight change × study arm interaction was associated with significant improvement in body image from baseline to six months. From baseline to 12 months, body image scores of intervention participants improved by 1.7 points more compared with scores of control participants; greater weight loss was associated with more improvement. Between baseline and 24 months, greater weight loss was associated with improvements in body image, perceived health, and health-related self-efficacy.

CONCLUSIONS

Participation in STRIDE improved body image, and losing weight improved perceived health and health-related self-efficacy.

Patients' ratings of genetic conditions validate a taxonomy to simplify decisions about preconception carrier screening via genome sequencing

Advances in genome sequencing and gene discovery have created opportunities to efficiently assess more genetic conditions than ever before. Given the large number of conditions that can be screened, the implementation of expanded carrier screening using genome sequencing will require practical methods of simplifying decisions about the conditions for which patients want to be screened. One method to simplify decision making is to generate a taxonomy based on expert judgment. However, expert perceptions of condition attributes used to classify these conditions may differ from those used by patients. To understand whether expert and patient perceptions differ, we asked women who had received preconception genetic carrier screening in the last 3 years to fill out a survey to rate the attributes (predictability, controllability, visibility, and severity) of several autosomal recessive or X-linked genetic conditions. These conditions were classified into one of five taxonomy categories developed by subject experts (significantly shortened lifespan, serious medical problems, mild medical problems, unpredictable medical outcomes, and adult-onset conditions). A total of 193 women provided 739 usable ratings across 20 conditions. The mean ratings and correlations demonstrated that participants made distinctions across both attributes and categories. Aggregated mean attribute ratings across categories demonstrated logical consistency between the key features of each attribute and category, although participants perceived little difference between the mild and serious categories. This study provides empirical evidence for the validity of our proposed taxonomy, which will simplify patient decisions for results they would like to receive from preconception carrier screening via genome sequencing.

Recovery challenges faced by bladder cancer survivors after recent cystectomy and urinary diversion

90

Background: Bladder cancer patients who are treated with cystectomy (bladder removal) and urinary diversion (bladder replacement) experience high rates of complications and hospital readmissions, and have substantial supportive care needs. Patient-reported priorities for improving early-phase survivorship care are lacking. Methods: On the basis of focus groups and in-depth interviews with 32 bladder cancer survivors about post-operative challenges, we developed a structured question listing 16 early survivorship challenges. We asked respondents to indicate which challenges had been difficult to manage at home. The item was part of a survey mailed to members of three Kaiser Permanente regions who had undergone cystectomy and urinary diversion for bladder cancer approximately 6 months previously (N = 197). Eligible patients were identified through health plan databases and chart review. Results: The response rate to the survey was 65%. Respondents reported an average of 3 challenges. The most commonly reported challenges pertained to coordination of medical care (69%), such as confusion about follow-up care, problems obtaining medical and ostomy supplies, knowing what complications to look for and who to notify if they occur, receiving home health care, or obtaining prompt medical advice. Other problems were caring for the urinary diversion (53%); dealing with urine leaks and incontinence (49%); problems with balance, vision, and dexterity (32%); difficulty managing emotions (23%); and management of lymphedema (11%) or incisional or parastomal hernias (7%). Conclusions: More than two thirds of bladder cancer survivors who had recently undergone cystectomy and urinary diversion struggled with medical care coordination. Managing self-care, complications, and emotional well-being after this major surgery can be difficult for patients, who must also navigate a variety of supportive services, such as medical follow-up with multiple departments and providers, home health services, and wound or ostomy care. A more formal approach to discharge and better communication among patients and providers will help improve early survivorship care for this group.

Validation of a Genomic Classifier for Predicting Post-Prostatectomy Recurrence in a Community Based Health Care Setting

PURPOSE

We determined the value of Decipher®, a genomic classifier, to predict prostate cancer outcomes among patients after prostatectomy in a community health care setting.

MATERIALS AND METHODS

We examined the experience of 224 men treated with radical prostatectomy from 1997 to 2009 at Kaiser Permanente Northwest, a large prepaid health plan in Portland, Oregon. Study subjects had aggressive prostate cancer with at least 1 of several criteria such as preoperative prostate specific antigen 20 ng/ml or greater, pathological Gleason score 8 or greater, stage pT3 disease or positive surgical margins at prostatectomy. The primary end point was clinical recurrence or metastasis after surgery evaluated using a time dependent c-index. Secondary end points were biochemical recurrence and salvage treatment failure. We compared the performance of Decipher alone to the widely used CAPRA-S (Cancer of the Prostate Risk Assessment Post-Surgical) score, and assessed the independent contributions of Decipher, CAPRA-S and their combination for the prediction of recurrence and treatment failure.

RESULTS

Of the 224 patients treated 12 experienced clinical recurrence, 68 had biochemical recurrence and 34 experienced salvage treatment failure. At 10 years after prostatectomy the recurrence rate was 2.6% among patients with low Decipher scores but 13.6% among those with high Decipher scores (p=0.02). When CAPRA-S and Decipher scores were considered together, the discrimination accuracy of the ROC curve was increased by 0.11 compared to the CAPRA-S score alone (combined c-index 0.84 at 10 years after radical prostatectomy) for clinical recurrence.

CONCLUSIONS

Decipher improves our ability to predict clinical recurrence in prostate cancer and adds precision to conventional pathological prognostic measures.

Weight maintenance following the STRIDE lifestyle intervention for individuals taking antipsychotic medications

OBJECTIVE

Individuals taking antipsychotic medications have increased risk of obesity-related early morbidity/mortality. This report presents weight maintenance results from a successful weight loss and behavioral lifestyle change program developed for people taking antipsychotic medications.

METHODS

STRIDE was a two-arm randomized controlled trial. Intervention participants attended weekly group meetings for 6 months, then monthly group meetings for 6 months. Assessments were completed at baseline and at 6, 12, and 24 months.

RESULTS

At 24 months, intervention participants lost 3.7% of baseline weight and control participants 2.1%, a non-significant difference. Fasting glucose results followed a similar pattern. There was a statistically significant difference, however, for fasting insulin-the intervention group's levels decreased between the end of the intensive intervention (at 6 months) and 24 months (10.1-7.91 μU/mL); control participants' levels increased (11.66 to 12.92 μU/mL) during this period. There were also fewer medical hospitalizations among intervention participants (5.7%) than controls (21.1%; χ(2) = 8.47, P = 0.004) during the 12- to 24-month post-intervention maintenance period.

CONCLUSIONS

Weight change differences between arms diminished following the intervention period, though fasting insulin levels continued to improve. Reduced hospitalizations suggest that weight loss, even with regain, may have long-term positive benefits for people taking antipsychotic medications and may reduce costs.

Symptom distress in patients with end-stage liver disease toward the end of life

Research on symptom distress experienced by patients with end-stage liver disease at the end of life is limited. The aims of the study were to describe presence, frequency, severity, and distress of symptoms in patients with end-stage liver disease toward the end of life and to describe the variability in psychological and physical symptom distress between and within patients over time. This study used a prospective, longitudinal descriptive design. Data were collected from 20 patients once a month for up to 6 months. Participants completed the Memorial Symptom Assessment Scale, which reports a total score, a Global Distress Index score, and a psychological and a physical distress score. Patients reported lack of energy, pain, difficulty sleeping, and feeling drowsy as the most frequent, severe, and distressing symptoms. Global Distress Index mean scores (measured on a 1-4 scale) ranged from 2.6 to 2.9 across time. There was notable variability in psychological and physical distress scores between and within patients across time. Gaining knowledge about the prevalent symptoms experienced by patients with end-stage liver disease and the trajectory of these symptoms is crucial for designing interventions that optimize well-being in patients with end-stage liver disease as they are approaching death.

The STRIDE weight loss and lifestyle intervention for individuals taking antipsychotic medications: a randomized trial

OBJECTIVES

The STRIDE study assessed whether a lifestyle intervention, tailored for individuals with serious mental illnesses, reduced weight and diabetes risk. The authors hypothesized that the STRIDE intervention would be more effective than usual care in reducing weight and improving glucose metabolism.

METHOD

The study design was a multisite, parallel two-arm randomized controlled trial in community settings and an integrated health plan. Participants who met inclusion criteria were ≥18 years old, were taking antipsychotic agents for ≥30 days, and had a body mass index ≥27. Exclusions were significant cognitive impairment, pregnancy/breastfeeding, recent psychiatric hospitalization, bariatric surgery, cancer, heart attack, or stroke. The intervention emphasized moderate caloric reduction, the DASH (Dietary Approaches to Stop Hypertension) diet, and physical activity. Blinded staff collected data at baseline, 6 months, and 12 months.

RESULTS

Participants (men, N=56; women, N=144; mean age=47.2 years [SD=10.6]) were randomly assigned to usual care (N=96) or a 6-month weekly group intervention plus six monthly maintenance sessions (N=104). A total of 181 participants (90.5%) completed 6-month assessments, and 170 (85%) completed 12-month assessments, without differential attrition. Participants attended 14.5 of 24 sessions over 6 months. Intent-to-treat analyses revealed that intervention participants lost 4.4 kg more than control participants from baseline to 6 months (95% CI=-6.96 kg to -1.78 kg) and 2.6 kg more than control participants from baseline to 12 months (95% CI=-5.14 kg to -0.07 kg). At 12 months, fasting glucose levels in the control group had increased from 106.0 mg/dL to 109.5 mg/dL and decreased in the intervention group from 106.3 mg/dL to 100.4 mg/dL. No serious adverse events were study-related; medical hospitalizations were reduced in the intervention group (6.7%) compared with the control group (18.8%).

CONCLUSIONS

Individuals taking antipsychotic medications can lose weight and improve fasting glucose levels. Increasing reach of the intervention is an important future step.
