Medical stabilization of adolescents with nutritional insufficiency: a clinical care path

Sex differences in electrolyte abnormalities indicating refeeding syndrome risk among hospitalized adolescents and young adults with eating disorders

BACKGROUND

Refeeding syndrome is the gravest possible medical complication in malnourished patients undergoing refeeding in the hospital. We previously reported that males with malnutrition secondary to eating disorders required more calories and had longer hospital stays than females; however, sex differences in electrolyte abnormalities indicating refeeding syndrome risk remain unknown. The objective of this study was to assess differences in electrolyte abnormalities indicating refeeding syndrome risk among male and female adolescents and young adults with eating disorders hospitalized for medical instability.

METHODS

We retrospectively reviewed the electronic medical records of 558 patients aged 9-25 years admitted to the University of California, San Francisco Eating Disorders Program for medical instability between May 2012 and August 2020. Serum was drawn per standard of care between 5 and 7 am each morning and electrolyte abnormalities indicating refeeding syndrome risk were defined as: hypophosphatemia (< 3.0 mg/dL), hypokalemia (< 3.5 mEq/L), and hypomagnesemia (< 1.8 mg/dL). Logistic regression was used to assess factors associated with electrolyte abnormalities indicating refeeding syndrome risk.

RESULTS

Participants included 86 (15.4%) males and 472 (84.6%) females, mean (SD) age 15.5 (2.8) years. Rates of refeeding hypophosphatemia (3.5%), hypokalemia (8.1%), and hypomagnesemia (11.6%) in males hospitalized with eating disorders were low, with no statistically significant differences from females. Older age was associated with higher odds of refeeding hypophosphatemia and hypomagnesemia. Lower percent median body mass index and greater weight suppression at admission were associated with higher odds of refeeding hypophosphatemia.

CONCLUSIONS

Rates of electrolyte abnormalities indicating refeeding syndrome risk were low in males hospitalized for eating disorders and rates did not significantly differ from females. Together with our finding that males have higher caloric requirements and longer hospital length of stay, the finding that electrolyte abnormalities indicating refeeding syndrome risk were not greater in males than females supports future research to evaluate the safety and efficacy of higher calorie and/or faster advancing refeeding protocols for males.

Linear growth in young people with restrictive eating disorders: "Inching" toward consensus

Background

While the assessment of acute medical stability in patients with eating disorders should never be minimized, careful attention toward other specific age-related consequences of malnutrition can improve psychological outcomes and reduce long-term, potentially irreversible medical complications, like linear growth impairment.

Review

While the impact of malnutrition on linear growth is widely recognized, emerging data highlight consensus in several key areas: the time from onset to time of diagnosis, age at illness onset, pubertal stage at illness onset, and adequacy of weight restoration to achieve catch-up growth. This review provides concrete and actionable steps to help providers identify and explore deviations in expected growth and development while prioritizing early and aggressive weight restoration to provide the best opportunity for catch-up linear growth in patients with eating disorders.

Conclusion

The impact of restrictive eating disorders on growth and development cannot be overstated, particularly in pre- and peripubertal patients. While many consequences of malnutrition are reversible, the loss of genetic height potential may prove irreversible without early and aggressive weight restoration.

A novel approach for autism spectrum condition patients with eating disorders: Analysis of treatment cost-savings

OBJECTIVE

In the current economic context, it is critical to ensure that eating disorder (ED) treatments are both effective and cost-effective. We describe the impact of a novel clinical pathway developed to better meet the needs of autistic patients with EDs on the length and cost of hospital admissions.

METHOD

The pathway was based on the Institute for Healthcare's Model of Improvement methodology, using an iterative Plan, Do, Study, Act format to introduce change and to co-produce the work with people with lived experience and with healthcare professionals. We explored the change in length and cost of admissions before and after the pathway was introduced.

RESULTS

Preliminary results suggest that the treatment innovations associated with this pathway have led to reduced lengths of admission for patients with the comorbidity, which were not seen for patients without the comorbidity. Estimated cost-savings were approximately £22,837 per patient and approximately £275,000 per year for the service as a whole.

CONCLUSION

Going forward, our aim is to continue to evaluate the effectiveness and cost-effectiveness of investment in the pathway to determine whether the pathway improves the quality of care for patients with a comorbid ED and autism and is good value for money.

Identification and Management of Eating Disorders in Children and Adolescents

Eating disorders are serious, potentially life-threatening illnesses afflicting individuals through the life span, with a particular impact on both the physical and psychological development of children and adolescents. Because care for children and adolescents with eating disorders can be complex and resources for the treatment of eating disorders are often limited, pediatricians may be called on to not only provide medical supervision for their patients with diagnosed eating disorders but also coordinate care and advocate for appropriate services. This clinical report includes a review of common eating disorders diagnosed in children and adolescents, outlines the medical evaluation of patients suspected of having an eating disorder, presents an overview of treatment strategies, and highlights opportunities for advocacy.

Earlier diagnosis in anorexia nervosa: better watch growth charts!

BACKGROUND

A better understanding of the healthcare pathway of children and adolescents with anorexia nervosa (AN) may contribute to earlier detection and better disease management. Here we measured and compared the symptomatic time to diagnosis (TTD) (time between the first symptoms, as reported by parents, and the diagnosis) and the auxological TTD (time between the deviation in the weight growth curve and the diagnosis).

METHODS

We performed a monocentric retrospective study including all patients age 9 years to 16 years who were hospitalized in Nantes University Hospital for AN between 2013 and 2016. We analysed the two TTDs by medical record review and growth curve investigation. TTDs were described by medians and Kaplan-Meier curves. Two profiles of patients were compared according to the kinetics of growth deviation and the occurrence of symptoms.

RESULTS

Among the 137 patients included, the median symptomatic and auxological TTDs was 7.0 months (IQR: 4.0-12.0) and 7.2 months (IQR: 2.0-18.0). TTDs were significantly different but clinically similar. For 48% of the patients, a deviation in the growth curve could have been noted at a median of 9.7 months (IQR: 3.0-18.0) before the first symptoms were reported by parents. Those patients showed significantly slower weight loss than did patients with first symptoms reported before growth deviation (weight loss rate 0.41% vs 1.90% per month, p < 0.0001).

CONCLUSIONS

Careful study of growth curves remains an essential step in detecting eating disorders, possibly allowing for earlier detection of the disease in nearly half of these patients.

Managing Eating Disorders on a General Pediatrics Unit: A Centralized Video Monitoring Pilot

Adolescents with severe eating disorders require hospitalization for medical stabilization. Supervision best practices for these patients are not established. This study sought to evaluate the cost and feasibility of centralized video monitoring (CVM) supervision on a general pediatric unit of an academic quaternary care center. This was a retrospective cohort study of nursing assistant (NA) versus CVM supervision for girls 12-18 years old admitted for medical stabilization of an eating disorder between September 2013 and March 2017. There were 37 consecutive admissions (NA = 23 and CVM = 14). NA median supervision cost was more expensive than CVM ($4,104/admission vs $1,166/admission, P < .001). Length of stay and days to weight gain were not statistically different. There were no occurances of family refusal of CVM, conversion from CVM to NA, technological failure, or unplanned discontinuation. Video monitoring was feasible and associated with lower supervision costs than one-to-one NA supervision. Larger samples in multiple centers are needed to confirm the safety, acceptability, and efficacy of CVM.

Daily Laboratory Monitoring is of Poor Health Care Value in Adolescents Acutely Hospitalized for Eating Disorders

PURPOSE

This study investigates how the clinical practice guideline-recommended laboratory monitoring for refeeding syndrome impacts management and outcomes of adolescents with eating disorders hospitalized for acute medical stabilization and examines the value of laboratory monitoring (defined as the patient health outcomes achieved per dollar spent).

METHODS

A retrospective chart review of medical admissions in a children's hospital between October 2010 and February 2014 was performed. Encounters were identified using International Classification of Diseases, Ninth Revision codes of eating disorders as primary or secondary diagnoses. Exclusion criteria included systemic diseases associated with significant electrolyte abnormalities. Chart abstraction was performed using a predetermined form. Costs were estimated by converting hospital-fixed Medicaid charges using a statewide cost-to-charge ratio.

RESULTS

Of the 196 patient encounters, there were no cases of refeeding syndrome. A total of 3,960 key recommended laboratories were obtained; 1.9% were below normal range and .05% were critical values. Of these, .28% resulted in supplementation; none were associated with a change in inpatient management. Total laboratory costs were $269,250.85; the calculated health care value of this monitoring is 1.04 × 10(-8) differential outcomes per dollar spent.

CONCLUSIONS

This study provides evidence to suggest that daily laboratory monitoring for refeeding syndrome is a poor health care value in the management of adolescents hospitalized for acute medical stabilization with eating disorders. This initial analysis suggests that starting at a relatively low caloric level and advancing nutrition slowly may negate the need for daily laboratory assessment, which may have important implications for current guidelines.
