This cohort study examines the hospital factors associated with disparities in access and quality of colon cancer care among Hispanic patients.

Physical and emotional consequences of excess weight as experienced by individuals with spinal cord injuries

CONTEXT/OBJECTIVE

Excess weight has the potential to carry a substantial physical and emotional burden. A better understanding of perceived consequences of excess weight may facilitate the development of patient-centered programs and interventions to promote weight management efforts in persons with spinal cord injury (SCI). The study objective was to describe consequences of excess weight from the personal perspectives of individuals with SCI.

DESIGN

Descriptive qualitative design using in-depth semi-structured interviews and thematic analysis.

SETTING

Veterans Health Administration (VHA) SCI System of Care.

PARTICIPANTS

Individuals with SCI (n-33).

OUTCOME MEASURES

Key themes from thematic analysis.

RESULTS

Participants were male (61%), ranged from 29 to 84 years of age, and about half had tetraplegia (55%). Five themes were identified that demonstrate negative consequences of excess weight experienced by individuals with SCI, including: (1) physical health conditions (including chronic conditions and SCI secondary conditions), (2) physical symptoms (such as pain, discomfort, and fatigue), (3) movement challenges, (4) appearance-related concerns, and (5) emotional impacts.

CONCLUSIONS

Carrying excess weight is concerning to individuals with SCI and in terms of consequences such onset or exacerbation of chronic conditions, SCI secondary conditions, physical symptoms, e.g. pain, movement impairment (including hampered mobility, difficult transfers and self-care), image/appearance concerns (e.g. body image, clothing misfit), and negative emotions (e.g. unhappy, sad, depressed). Our findings may inform SCI healthcare providers about the consequences of excess weight as experienced by individuals with SCI, highlighting what matters most to persons with SCI and guiding a patient-centered approach to weight management in this population.

Disparities in Access, Quality, and Clinical Outcome for Latino Californians with Colon Cancer

OBJECTIVE

To compare access, quality, and clinical outcomes between Latino and non-Latino White Californians with colon cancer.

SUMMARY BACKGROUND DATA

Racial and ethnic disparities in cancer care remain understudied, particularly among patients who identify as Latino. Exploring potential mechanisms, including differential utilization of high-volume hospitals, is an essential first step to designing evidence-based policy solutions.

METHODS

We identified all adults diagnosed with colon cancer between January 1, 2010 and December 31, 2020 from a statewide cancer registry linked to hospital administrative records. We compared survival, access (stage at diagnosis, receipt of surgical care, treatment at a high-volume hospital), and quality of care (receipt of adjuvant chemotherapy, adequacy of lymph node resection) between patients who identified as Latino and as non-Latino White.

RESULTS

75,543 patients met inclusion criteria, including 16,071 patients who identified as Latino (21.3%). Latino patients were significantly less likely to undergo definitive surgical resection (marginal difference [MD] -0.72 percentage points, 95% CI -1.19,-0.26), have an operation in a timely fashion (MD -3.24 percentage points, 95% CI -4.16,-2.32), or have an adequate lymphadenectomy (MD -2.85 percentage points, 95% CI -3.59,-2.12) even after adjustment for clinical and sociodemographic factors. Latino patients treated at high-volume hospitals were significantly less likely to die and more likely to meet access and quality metrics.

CONCLUSIONS

Latino colon cancer patients experienced delays, segregation, and lower receipt of recommended care. Hospital-level colectomy volume appears to be strongly associated with access, quality, and survival--especially for patients who identify as Latino--suggesting that directing at-risk cancer patients to high-volume hospitals may improve health equity.

Nutrition and eating beliefs and behaviors among individuals with spinal cord injuries and disorders: Healthy or misconceived?

PURPOSE/OBJECTIVE

Nutrition knowledge, beliefs, and behaviors have important implications for managing and preventing chronic and injury-related secondary conditions in persons with spinal cord injuries and disorders (SCI/D). Yet, the unique dietary and nutritional needs and recommendations specific to individuals with SCI/D and their eating beliefs and behaviors have been understudied. Aim is to describe nutrition and eating beliefs and behaviors from the perspectives of individuals with SCI/D.

RESEARCH METHOD/DESIGN

Descriptive qualitative design using in-depth semistructured interviews with a national sample of veterans with SCI/D (n = 33). Audio-recorded and transcribed verbatim transcripts were coded and analyzed using thematic analysis.

RESULTS

Participants were male (61%), aged 29-84 years, and 55% had tetraplegia. Five key themes were identified: extreme fasting/caloric restriction, perceived healthy eating behaviors, perceived unhealthy eating behaviors, modified eating behaviors due to SCI/D-related symptoms, and food/preparation choices based on abilities/independence and access.

CONCLUSIONS/IMPLICATIONS

Nutrition among veterans with SCI/D may be impacted by many factors, such as nutrition knowledge and beliefs/behaviors about "healthy" and "unhealthy" nutrition, fasting, caloric restriction, imbalanced intake of macro- and micronutrients, overconsumption relative to energy needs, injury-related secondary complications, postinjury body composition and function changes, impairments related to satiety and hunger signals, and difficulty in obtaining and preparing food. Study findings provide many areas that would benefit from intervention. Findings can be used to inform ideal nutrition and healthy eating beliefs and behaviors which are important because nutritional inadequacies can lead to diet-related diseases, may exacerbate SCI secondary conditions, and lead to poor overall health.

Why may patients with spinal cord injury be overlooked for obesity screening in the Veterans Health Administration? Qualitative research of the perspectives of patients and healthcare providers

PURPOSE

We sought to describe factors influencing reduced rates of obesity screening for patients with spinal cord injury (SCI) in the United States Veterans Health Administration (VA) and to foster potential solutions.

MATERIALS AND METHODS

Semi-structured interviews with healthcare providers and patients with SCI who were recruited nationally from diverse VAs. We performed rapid qualitative analysis using content analysis of interview data.

RESULTS

There were 36 providers and 37 patients. We identified provider, patient, and system level barriers to obesity screening for individuals with SCI. Overarching barriers involved provider and patient perceptions that obesity screening is a low priority compared to other health conditions, and body mass index is of low utility. Other obesity screening barriers were related to measuring weight (i.e., insufficient equipment, unknown wheelchair weight, staffing shortages, measurement errors, reduced access to annual screening, insufficient time, patient preference not to be weighed) and measuring height (i.e., insufficient guidance and equipment to this population, measurement errors).

CONCLUSIONS

Barriers to obesity screenings exist for patients with SCI receiving care in VA. Healthcare provider and patient interviews suggest possible solutions, including standardizing height and weight measurement processes, ensuring equipment availability in clinics, clarifying guidelines, and offering support to providers and patients.IMPLICATIONS FOR REHABILITATIONIndividuals with spinal cord injury (SCI) have higher rates of obesity, but are often overlooked for annual obesity screening, even in clinic settings designed to care for individuals with SCI.Results may help tailor guidelines/education for healthcare and rehabilitation providers offering them guidance for improving obesity screening for individuals with SCI by standardizing weight and height measurement and documentation. To facilitate this, findings highlight the need for resources, such as ensuring clinics have necessary equipment, and increasing patient access to support and equipment.Improving the provision of obesity screening for individuals with SCI is necessary to improve health outcomes and patient satisfaction with care.

Interaction between increasing body mass index and spinal cord injury to the probability of developing a diagnosis of nonalcoholic fatty liver disease

Background

The prevalence of obesity and comorbidities is high in the population with spinal cord injury (SCI). We sought to determine the effect of SCI on the functional form of the relationship between body mass index (BMI) and risk of developing nonalcoholic fatty liver disease (NAFLD), and assess whether SCI-specific mapping of BMI to risk of developing NAFLD is needed.

Methods

Longitudinal cohort study comparing Veterans Health Administration patients with a diagnosis of SCI to a 1:2 matched control group without SCI. The relationship between BMI and development of NAFLD at any time was assessed with propensity score matched Cox regression models; NAFLD development at 10-year with a propensity score matched logistic model. The positive predictive value of developing NAFLD at 10 years was calculated for BMI 19-45 kg/m2.

Results

14,890 individuals with SCI met study inclusion criteria, and 29,780 Non-SCI individuals in matched control group. Overall, 9.2% in SCI group and 7.3% in Non-SCI group developed NAFLD during the study period. A logistic model assessing the relationship between BMI and the probability of developing a diagnosis of NAFLD demonstrated that the probability of developing disease increased as BMI increased in both cohorts. The probability was significantly higher in the SCI cohort at each BMI threshold (p < 0.01), and increased at a higher rate compared with the Non-SCI cohort as BMI increased 19-45 kg/m2. Positive predictive value for developing a diagnosis of NAFLD was higher in the SCI group for any given BMI threshold from 19 kg/m2 to BMI 45 kg/m2.

Conclusions

The probability of developing NAFLD is greater in individuals with SCI than without SCI, at every BMI level 19 kg/m2 to 45 kg/m2. Individuals with SCI may warrant a higher level of suspicion and closer screening for NAFLD. The association of SCI and BMI is not linear.

Despite Increasing Costs, Perfusion Machines Expand the Donor Pool of Livers and Could Save Lives

INTRODUCTION

Liver transplantation is a highly successful treatment for liver failure and disease. However, demand continues to outstrip our ability to provide transplantation as a treatment. Many livers initially considered for transplantation are not used because of concerns about their viability or logistical issues. Recent clinical trials have shown discarded livers may be viable if they undergo machine perfusion, which allows a more objective assessment of liver quality.

METHODS

Using the Scientific Registry of Transplant Recipients dataset, we examined discarded and unretrieved organs to determine their eligibility for perfusion. We then used a Markov decision-analytic model to perform a cost-effectiveness analysis of two competing transplant strategies: Static Cold Storage (SCS) alone versus Static Cold Storage and Normothermic Machine Perfusion (NMP) of discarded organs.

RESULTS

The average predicted successful transplants after perfusion was 385, representing a 5.8% increase in the annual yield of liver transplants. Our cost-effectiveness analysis found that the SCS strategy generated 4.64 quality-adjusted life years (QALYs) and cost $479,226. The combined SCS + NMP strategy generated 4.72 QALYs and cost $481,885. The combined SCS + NMP strategy had an incremental cost-effectiveness ratio of $33,575 per additional QALY over the 10-year study horizon.

CONCLUSIONS

Machine perfusion of livers currently not considered viable for transplant could increase the number of transplantable grafts by approximately 5% per year and is cost-effective compared to Static Cold Storage alone.

The impact of the COVID-19 pandemic on individuals living with spinal cord injury: A qualitative study

PURPOSE/OBJECTIVE

To explore the impact of the COVID-19 pandemic as experienced and reported by individuals living with a spinal cord injury (SCI).

RESEARCH METHOD/DESIGN

Descriptive qualitative design using in-depth semistructured interviews with individuals with SCI (n = 33) followed by thematic analysis.

RESULTS

Three main themes described impacts of the COVID-19 pandemic. (a) Impact on health care use; subthemes elaborated that this was attributable to in-person health care facility restrictions or individual decisions to delay care. Individuals with SCI experienced lapses in primary and SCI-specialty care, rehabilitation/therapy services, and home care, but some made use of telehealth services. (b) Impact on weight and/or weight management lifestyle behaviors; subthemes discussed that engagement in physical activity declined because of fitness center closures, recreational activity cancellations, and safety precautions limiting community-based and outdoor activities. The pandemic disrupted participants' independence in purchasing and making preferred food selections which impacted healthy eating. Participants ate due to boredom, at nonmealtimes, and consumed unhealthy foods during the pandemic. (c) Impact on psychosocial factors; included subthemes noting reduced social interactions, social participation, and ability to pursue pastimes with family, friends, and groups they belonged to. The pandemic also triggered emotional reactions such as worry, fear, doubt, demotivation, and feelings of social isolation.

CONCLUSIONS

Our findings highlight the magnitude of consequences faced by individuals with SCI when restrictions to health care, healthy lifestyle endeavors, and social participation occurred during the COVID-19 pandemic. Findings may inform SCI health care providers on what is needed in response to future public health or natural disaster crises. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Preventive Health Screening in Veterans Undergoing Bariatric Surgery

INTRODUCTION

Individuals with obesity are vulnerable to low rates of preventive health screening. Veterans with obesity seeking bariatric surgery are also hypothesized to have gaps in preventive health screening. Evaluation in a multidisciplinary bariatric surgery clinic is a point of interaction with the healthcare system that could facilitate improvements in screening.

METHODS

This is a retrospective cohort study of 381 consecutive patients undergoing bariatric surgery at a Veterans Affairs Hospital from January 2010 to October 2021. Age- and sex-appropriate health screening rates were determined at initial referral to a multidisciplinary bariatric surgery clinic and at the time of surgery. Rates of guideline concordance at both time points were compared using McNemar's test. Univariate and multivariate analyses were performed to identify the risk factors for nonconcordance.

RESULTS

Concordance with all recommended screening was low at initial referral and significantly improved by time of surgery (39.1%‒63.8%; p<0.001). Screening rates significantly improved for HIV (p<0.001), cervical cancer (p=0.03), and colon cancer (p<0.001). Increases in BMI (p=0.005) and the number of indicated screening tests (p=0.029) were associated with reduced odds of concordance at initial referral. Smoking history (p=0.012) and increasing distance to the nearest Veterans Affairs Medical Center (p=0.039) were associated with reduced odds of change from nonconcordance at initial referral to concordance at the time of surgery.

CONCLUSIONS

Rates of preventive health screening in Veterans with obesity are low. A multidisciplinary bariatric surgery clinic is an opportunity to improve preventive health screening in Veterans referred for bariatric surgery.

Assessment of Second Primary Cancer Risk Among Men Receiving Primary Radiotherapy vs Surgery for the Treatment of Prostate Cancer

IMPORTANCE

Shared decision-making is an important part of the treatment selection process among patients with prostate cancer. Updated information is needed regarding the long-term incidence and risk of second primary cancer after radiotherapy vs nonradiotherapy treatments, which may help to inform discussions of risks and benefits for men diagnosed with prostate cancer.

OBJECTIVE

To assess the current incidence and risk of developing a second primary cancer after receipt of radiotherapy vs nonradiotherapy treatments for prostate cancer.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study used the Veterans Affairs Corporate Data Warehouse to identify 154 514 male veterans 18 years and older who had localized prostate cancer (tumor stages T1-T3) diagnosed between January 1, 2000, and December 31, 2015, and no cancer history. A total of 10 628 patients were excluded because of (1) incomplete treatment information for the year after diagnosis, (2) receipt of both radiotherapy and a surgical procedure in the year after diagnosis, (3) receipt of radiotherapy more than 1 year after diagnosis, (4) occurrence of second primary cancer or death within 1 year or less after diagnosis, (5) prostate-specific antigen value greater than 99 ng/mL within 6 months before diagnosis, or (6) no recorded Veterans Health Administration service after diagnosis. The remaining 143 886 patients included in the study had a median (IQR) follow-up of 9 (6-13) years. Data were analyzed from May 1, 2021, to May 22, 2022.

MAIN OUTCOMES AND MEASURES

Diagnosis of a second primary cancer more than 1 year after prostate cancer diagnosis.

RESULTS

Among 143 886 male veterans (median [IQR] age, 65 [60-71] years) with localized prostate cancer, 750 (0.5%) were American Indian or Alaska Native, 389 (0.3%) were Asian, 37 796 (26.3%) were Black or African American, 933 (0.6%) were Native Hawaiian or other Pacific Islander, 91 091 (63.3%) were White, and 12 927 (9.0%) were of unknown race; 7299 patients (5.1%) were Hispanic or Latino, 128 796 (89.5%) were not Hispanic or Latino, and 7791 (5.4%) were of unknown ethnicity. A total of 52 886 patients (36.8%) received primary radiotherapy, and 91 000 (63.2%) did not. A second primary cancer more than 1 year after prostate cancer diagnosis was present in 4257 patients (3.0%), comprising 1955 patients (3.7%) in the radiotherapy cohort and 2302 patients (2.5%) in the nonradiotherapy cohort. In the multivariable analyses, patients in the radiotherapy cohort had a higher risk of second primary cancer compared with those in the nonradiotherapy cohort at years 1 to 5 after diagnosis (hazard ratio [HR], 1.24; 95% CI, 1.13-1.37; P < .001), with higher adjusted HRs in the subsequent 15 years (years 5-10: 1.50 [95% CI, 1.36-1.65; P < .001]; years 10-15: 1.59 [95% CI, 1.37-1.84; P < .001]; years 15-20: 1.47 [95% CI, 1.08-2.01; P = .02).

CONCLUSIONS AND RELEVANCE

In this cohort study, patients with prostate cancer who received radiotherapy were more likely to develop a second primary cancer than patients who did not receive radiotherapy, with increased risk over time. Although the incidence and risk of developing a second primary cancer were low, it is important to discuss the risk with patients during shared decision-making about prostate cancer treatment options.

Kidney Stone Events Following Parathyroidectomy vs Nonoperative Management for Primary Hyperparathyroidism

CONTEXT

Primary hyperparathyroidism (PHPT) is associated with an increased risk of kidney stones. Few studies account for PHPT severity or stone risk when comparing stone events after parathyroidectomy vs nonoperative management.

OBJECTIVE

Compare the incidence of kidney stone events in PHPT patients treated with parathyroidectomy vs nonoperative management.

DESIGN

Longitudinal cohort study with propensity score inverse probability weighting and multivariable Cox proportional hazards regression.

SETTING

Veterans Health Administration integrated health care system.

PATIENTS

A total of 44 978 patients with > 2 years follow-up after PHPT diagnosis (2000-2018); 5244 patients (11.7%) were treated with parathyroidectomy.

MAIN OUTCOMES MEASURE

Clinically significant kidney stone event.

RESULTS

The cohort had a mean age of 66.0 years, was 87.8% male, and 66.4% White. Patients treated with parathyroidectomy had higher mean serum calcium (11.2 vs 10.8mg/dL) and were more likely to have a history of kidney stone events. Among patients with baseline history of kidney stones, the unadjusted incidence of ≥ 1 kidney stone event was 30.5% in patients managed with parathyroidectomy (mean follow-up, 5.6 years) compared with 18.0% in those managed nonoperatively (mean follow-up, 5.0 years). Patients treated with parathyroidectomy had a higher adjusted hazard of recurrent kidney stone events (hazard ratio [HR], 1.98; 95% CI, 1.56-2.51); however, this association declined over time (parathyroidectomy × time: HR, 0.80; 95% CI, 0.73-0.87).

CONCLUSION

In this predominantly male cohort with PHPT, patients treated with parathyroidectomy continued to be at higher risk of kidney stone events in the immediate years after treatment than patients managed nonoperatively, although the adjusted risk of stone events declined with time, suggesting a benefit to surgical treatment.

Rates, Variability, and Predictors of Screening for Obesity: Are Individuals with Spinal Cord Injury Being Overlooked?

INTRODUCTION

Individuals with spinal cord injury (SCI) are vulnerable to obesity. Annual obesity screening using body mass index (BMI) is the standard of care mandated by US Veterans Health Administration (VHA) guidelines. Our objective was to determine the rates, variability, and predictors of guideline-concordant annual screening for obesity, given potential challenges of height and weight measurements in individuals with SCI.

METHODS

This is a cross-sectional retrospective study using US national VA databases. We identified all VHA patients with chronic SCI in the fiscal year (FY) 2019, their treating facility and frequency of recorded height and weight. We applied mixed-effects logistic regression models to assess associations between annual BMI screening and patient- and facility-level characteristics.

RESULTS

Of 20,978 individuals with chronic SCI in VHA in FY19, guideline-concordant annual BMI screening was lacking in 37.9%. Accounting for facility-level factors (geographic region, SCI facility type, volume of patients with SCI treated at the facility), a mixed-effects logistic regression model demonstrated that lack of annual obesity screening was significantly associated with older patient age (p < 0.001) and fewer outpatient encounters (p < 0.001) but not other patient-level factors such as sex, race, level of injury, or rurality. The rate of obesity screening among different facilities within VHA varied widely from 11.1% to 75.7%.

CONCLUSION

A large proportion of persons with SCI receiving care in VHA do not receive guideline-concordant annual obesity screening, an especially acute problem in some facilities. Older patients with fewer outpatient encounters are more likely to be missed. To inform the design of interventions to improve identification and documentation of obesity, further study is needed to assess potential barriers to obesity screening in the population with SCI.

Association of Parathyroidectomy With 5-Year Clinically Significant Kidney Stone Events in Patients With Primary Hyperparathyroidism

OBJECTIVE

Patients with primary hyperparathyroidism (PHPT) are at increased risk of kidney stones. Guidelines recommend parathyroidectomy in patients with PHPT with a history of stone disease. This study aimed to compare the 5-year incidence of clinically significant kidney stone events in patients with PHPT treated with parathyroidectomy versus nonoperative management.

METHODS

We performed a longitudinal cohort study of patients with PHPT in a national commercial insurance claims database (2006-2019). Propensity score inverse probability weighting-adjusted multivariable regression models were calculated.

RESULTS

We identified 7623 patients aged ≥35 years old with continuous enrollment >1 year before and >5 years after PHPT diagnosis. A total of 2933 patients (38.5%) were treated with parathyroidectomy. The cohort had a mean age of 66.5 years, 5953 (78.1%) were female, and 5520 (72.4%) were White. Over 5 years, the unadjusted incidence of ≥1 kidney stone event was higher in patients who were managed with parathyroidectomy compared with those who were managed nonoperatively overall (5.4% vs 4.1%, respectively) and among those with a history of kidney stones at PHPT diagnosis (17.9% vs 16.4%, respectively). On multivariable analysis, parathyroidectomy was associated with no statistically significant difference in the odds of a 5-year kidney stone event among patients with a history of kidney stones (odds ratio, 1.03; 95% CI, 0.71-1.50) or those without a history of kidney stones (odds ratio, 1.16; 95% CI, 0.84-1.60).

CONCLUSION

Based on this claim analysis, there was no difference in the odds of 5-year kidney stone events in patients with PHPT who were treated with parathyroidectomy versus nonoperative management. Time horizon for benefit should be considered when making treatment decisions for PHPT based on the risk of kidney stone events.

Characteristics of mental health trials registered in ClinicalTrials.gov

The ClinicalTrials.gov registry was established in 2000 to address concerns about publication bias and public access to information about clinical trials. We aimed to evaluate differences between for-profit and non-profit sponsors of efficacy mental health trials registered in ClinicalTrials.gov on key trial characteristics that relate to data integrity. We also sought to evaluate whether the registry is fulfilling its purpose as a means of promoting transparency between researchers and the public by providing complete and quality information about the trials it contains. We found that trials tend to be small, use a placebo instead of an active comparator, and employ randomization and blinding. We discuss the implications of these design characteristics and the limitations of the registry.

Are parental self-efficacy and family flexibility mediators of treatment for anorexia nervosa?

OBJECTIVE

Family-based treatment (FBT) for adolescent anorexia nervosa (AN) promotes faster weight restoration when compared to other treatments. However, the mechanisms through which this occurs are not clarified. This study explored the trajectories of parental self-efficacy and perceived family flexibility during FBT and systemic family therapy (SyFT). We also explored whether parental self-efficacy mediates the effects of treatment on weight gain early in treatment.

METHOD

158 adolescents (12-18 years old; 89% girls) and their parents were randomized to FBT or SyFT. Parental self-efficacy as well as adolescents' and parental perceptions of the family's flexibility were collected at baseline and at sessions 2, 4, 6, and 8.

RESULTS

Over time, only parents in FBT reported significantly greater self-efficacy. The change in maternal self-efficacy over the first 8 weeks of treatment was a significant mediator of session 10 weight gain. There were no significant group differences in perceived flexibility by session 8.

DISCUSSION

Both parents in FBT and mothers in SyFT understand early the need to change their family's rules and roles. However, the specific strategies of FBT appear to mediate early weight gain in AN.

A qualitative analysis of male eating disorder symptoms

Insights into how males experience eating disorder symptoms early in the course of illness are important to improve detection efforts and may also provide valuable information for treatment. In this qualitative study, 10 adolescent males and 10 matched female patients completed standardized questionnaires and were interviewed. Results indicated that although there were many similarities between the genders, females were more likely to describe the involvement of family systems and males were more likely to describe involvement in sports as being catalysts for their disorders. Males in this study were more positive about being in treatment.

An exploratory examination of patient and parental self-efficacy as predictors of weight gain in adolescents with anorexia nervosa

OBJECTIVE

To determine whether increases in adolescent or parental self-efficacy predicted subsequent weight gain in two different therapies for adolescent anorexia nervosa (AN).

METHOD

Participants were 121 adolescents with AN (M = 14.4 years, SD = 1.6), from a two-site randomized clinical trial for family-based treatment (FBT) and individual adolescent focused therapy (AFT). Both adolescent and parental self-efficacy were assessed at baseline and sessions 2, 4, 6, and 8. Adolescent self-efficacy was assessed using a generic measure of self-efficacy, while parental self-efficacy was assessed using a measure specific to the recovery of an eating disorder. Weight was assessed at baseline, sessions 1 through 8, and end of treatment. Mixed-effects models were used to evaluate the relation between patient and parent self-efficacy and subsequent weight gain, controlling for weight at the previous time point.

RESULTS

For families who received FBT, greater within-treatment increases in parental self-efficacy predicted greater subsequent adolescent weight gain compared to those who received FBT with lesser change in parental self-efficacy and those who received AFT. Interestingly, adolescent self-efficacy did not significantly predict subsequent weight gain.

DISCUSSION

Greater increases in parental self-efficacy predicted significantly greater subsequent weight gain for adolescents who received FBT, but the same was not true for adolescents who received AFT. Neither overall level nor change in adolescent self-efficacy significantly predicted subsequent weight gain in either treatment group. These findings emphasize the importance of increasing parental self-efficacy in FBT in order to impact adolescent weight outcomes.

Development and evaluation of a treatment fidelity instrument for family-based treatment of adolescent anorexia nervosa

OBJECTIVE

This study provides data on the psychometric properties of a newly developed measure of treatment fidelity in Family-Based Treatment (FBT) for adolescent anorexia nervosa (AN). The Family Therapy Fidelity and Adherence Check (FBT-FACT) was created to evaluate therapist adherence and competency on the core interventions in FBT.

METHOD

Participants were 45 adolescents and their families sampled from three randomized clinical trials evaluating treatment for AN. Trained fidelity raters evaluated 19 therapists across 90 early session recordings using the FBT-FACT. They also rated an additional 15 session 1 recordings of an alternate form of family therapy-Systemic Family Therapy for the purpose of evaluating discriminant validity of the FBT-FACT. The process of development and the psychometric properties of the FBT-FACT are presented.

RESULTS

Overall fidelity ratings for each session demonstrated moderate to strong inter-rater agreement. Internal consistency of the measure was strong for sessions 1 and 2 and poor for session 3. Principal components analysis suggests sessions 1 and 2 are distinct interventions.

DISCUSSION

The FBT-FACT demonstrates good reliability and validity as a measure of treatment fidelity in the early phase of FBT.

Suprathreshold duloxetine for treatment-resistant depression, anorexia nervosa binge-purging type, and obsessive-compulsive disorder: a case report

Duloxetine, a serotonin norepinephrine reuptake inhibitor (SNRI) indicated for the treatment of depression, is used for off-label purposes such as treatment-resistant obsessive compulsive disorder, bulimia, and binge eating disorder. Although establishing a dose-response relationship for antidepressants in the treatment of depression is difficult, it is possible that for certain patterns of comorbidity, suprathreshold doses may be important to achieve remission. There is currently a paucity of literature regarding the use of suprathreshold doses of duloxetine in treatment refractory cases. This case report describes a clinical situation in which suprathreshold duloxetine was used to treat a patient with severe depression as well as co-morbid anorexia nervosa binge-purging type and obsessive compulsive disorder. One year after the initial increase to 180mg, the patient's mood remains improved. Our clinical account appears to be only the second case report describing the efficacy of high dose 180mg duloxetine in the management of symptoms refractory to treatment at standard doses.
