A preliminary study of telemedicine for patients with hepatic glycogen storage disease and their healthcare providers: from bedside to home site monitoring

Quality assessment of mHealth apps: a scoping review

Introduction

The number of mHealth apps has increased rapidly during recent years. Literature suggests a number of problems and barriers to the adoption of mHealth apps, including issues such as validity, usability, as well as data privacy and security. Continuous quality assessment and assurance systems might help to overcome these barriers. Aim of this scoping review was to collate literature on quality assessment tools and quality assurance systems for mHealth apps, compile the components of the tools, and derive overarching quality dimensions, which are potentially relevant for the continuous quality assessment of mHealth apps.

Methods

Literature searches were performed in Medline, EMBASE and PsycInfo. Articles in English or German language were included if they contained information on development, application, or validation of generic concepts of quality assessment or quality assurance of mHealth apps. Screening and extraction were carried out by two researchers independently. Identified quality criteria and aspects were extracted and clustered into quality dimensions.

Results

A total of 70 publications met inclusion criteria. Included publications contain information on five quality assurance systems and further 24 quality assessment tools for mHealth apps. Of these 29 systems/tools, 8 were developed for the assessment of mHealth apps for specific diseases, 16 for assessing mHealth apps for all fields of health and another five are not restricted to health apps. Identified quality criteria and aspects were extracted and grouped into a total of 14 quality dimensions, namely "information and transparency", "validity and (added) value", "(medical) safety", "interoperability and compatibility", "actuality", "engagement", "data privacy and data security", "usability and design", "technology", "organizational aspects", "social aspects", "legal aspects", "equity and equality", and "cost(-effectiveness)".

Discussion

This scoping review provides a broad overview of existing quality assessment and assurance systems. Many of the tools included cover only a few dimensions and aspects and therefore do not allow for a comprehensive quality assessment or quality assurance. Our findings can contribute to the development of continuous quality assessment and assurance systems for mHealth apps.

Towards values-based healthcare for inherited metabolic disorders: An overview of current practices for persons with liver glycogen storage disease and fatty acid oxidation disorders

Value-based healthcare (VBHC) intends to achieve better outcomes for patients, to improve quality of patient care, with reduced costs. Four dimensions define a model of intimately related value-pillars: personal value, allocative value, technical value, and societal value. VBHC is mostly applied in common diseases, and there are fundamental challenges in applying VBHC strategies to low volume, high complex healthcare situations, such as rare diseases, including inherited metabolic disorders. This article summarizes current practices at various academical domains (i.e., research, healthcare, education, and training) that (aim to) increase values at various value-pillars for persons with liver glycogen storage diseases or fatty acid oxidation disorders and their families. Future perspectives may include facilitating virtual networks to function as integrated practice units, improving measurement of outcomes, and creating information technology platforms to overcome the ethical, legal, societal, and technical challenges of data sharing for healthcare and research purposes.

An update on the US adult thalassaemia population: a report from the CDC thalassaemia treatment centres

Thalassaemia is caused by genetic globin defects leading to anaemia, transfusion-dependence and comorbidities. Reduced survival and systemic organ disease affect transfusion-dependent thalassaemia major and thalassaemia intermedia. Recent improvements in clinical management have reduced thalassaemia mortality. The therapeutic landscape of thalassaemia may soon include gene therapies as functional cures. An analysis of the adult US thalassaemia population has not been performed since the Thalassemia Clinical Research Network cohort study from 2000 to 2006. The Centers for Disease Control and Prevention supported US thalassaemia treatment centres (TTCs) to compile longitudinal information on individuals with thalassaemia. This dataset provided an opportunity to evaluate iron balance, chelation, comorbidities and demographics of adults with thalassaemia receiving care at TTCs. Two adult cohorts were compared: those over 40 years old (n = 75) and younger adults ages 18-39 (n = 201). The older adult cohort was characterized by higher numbers of iron-related comorbidities and transfusion-related complications. By contrast, younger adults had excess hepatic and cardiac iron and were receiving combination chelation therapy. The ethnic composition of the younger cohort was predominantly of Asian origin, reflecting the demographics of immigration. These findings demonstrate that comprehensive care and periodic surveys are needed to ensure optimal health and access to emerging therapies.

A generic emergency protocol for patients with inborn errors of metabolism causing fasting intolerance: A retrospective, single-center study and the generation of www.emergencyprotocol.net

Patients with inborn errors of metabolism causing fasting intolerance can experience acute metabolic decompensations. Long-term data on outcomes using emergency letters are lacking. This is a retrospective, observational, single-center study of the use of emergency letters based on a generic emergency protocol in patients with hepatic glycogen storage diseases (GSD) or fatty acid oxidation disorders (FAOD). Data on hospital admissions, initial laboratory results, and serious adverse events were collected. Subsequently, the website www.emergencyprotocol.net was generated in the context of the CONNECT MetabERN eHealth project following multiple meetings, protocol revisions, and translations. Representing 470 emergency protocol years, 127 hospital admissions were documented in 54/128 (42%) patients who made use of emergency letters generated based on the generic emergency protocol. Hypoglycemia (here defined as glucose concentration < 3.9 mmol/L) was reported in only 15% of hospital admissions and was uncommon in patients with ketotic GSD and patients with FAOD aged >5 years. Convulsions, coma, or death was not documented. By providing basic information, emergency letters for individual patients with hepatic GSD or the main FAOD can be generated at www.emergencyprotocol.net, in nine different languages. Generic emergency protocols are safe and easy for home management by the caregivers and the first hour in-hospital management to prevent metabolic emergencies in patients with hepatic GSD and medium-chain Acyl CoA dehydrogenase deficiency. The website www.emergencyprotocol.net is designed to support families and healthcare providers to generate personalized emergency letters for patients with hepatic GSD and the main FAOD.

Rare disease care pathways in the EU: from odysseys and labyrinths towards highways

Care pathways (CPW) are used worldwide to structure care processes within the patient-centered care concept. Rare diseases (RD), defined as those affecting less than 5 persons per 10,000 and including up to 10,000 different diseases, present unique challenges to CPW development due to their rarity and a large number of disease entities, chronic and frequently disabling nature, heterogeneous manifestation, multisystem involvement, and complexity in diagnostics and treatment. However, failure to develop RD CPWs eventually leads to long diagnostic odysseys, limited and unequal access to RD treatments, and a huge burden of complex care coordination that lies on the shoulders of patients and their families, imposing many personal, professional and social life difficulties, and diminishing their quality of life. In the development of RD CPW, there is a need to ensure smooth horizontal and vertical care integration, multiple transitions, and long-term care coordination across many geographically distant care providers and to find a fine balance between centralized expertise-based, complex, highly specialized services and possibilities for local care provision, patient empowerment and self-management, and digital healthcare. Established in 2017, European Reference Networks may have a high added value through an increase in accessibility and quality of services, economies of scale, scope and speed in the development of lacking evidence-based, educational and other resources for RD CPW, and speeding up innovation development and translation into RD CPW. However, their full benefits may only be reaped through a pan-European collaboration, universal acceptance of common European values and open-mindedness for sometimes disruptive innovation in the provision of healthcare across all Member States of the European Union.

The Impact of Telemedicine for Monitoring and Treatment of Phenylketonuria Patients on Metabolic Outcome During Coronavirus Disease-19 Outbreak

Background: The prognosis of phenylketonuria (PKU) in terms of neurocognitive outcome is directly related to lifelong phenylalanine (Phe) levels and adherence to treatment. Monitoring and treatment of PKU patients can be complicated in challenging circumstances as pandemics. This study aims to evaluate the impact of telemedicine for monitoring and treatment of PKU patients on metabolic outcome during coronavirus disease-19 (COVID-19) outbreak. Materials and Methods: Patients who were diagnosed as PKU and treated with low Phe diet, tetrahydrobiopterin (BH4), or BH4 adjunct with low Phe diet were enrolled. Study period was divided into two periods: prepandemic period wherein patients were followed up in outpatients' clinic and during pandemic wherein telemedicine was used. Demographic findings, laboratory results, and therapy responses were reviewed retrospectively and compared between the two periods. All procedures were in accordance with the ethical standards of the local ethical committee of Cerrahpasa Medical Faculty (17/11/2020-151640) and with the Helsinki Declaration of 1975, as revised in 2013. Results: Ninety-three (n = 93) patients were enrolled to this study. The ratio of the samples with Phe levels in the recommended ranges was found to be statistically higher during the pandemic wherein an online monitoring system was used in all treatment modalities (p < 0.05). The decrease in Phe washout frequency was statistically significant during the pandemic in the low Phe diet group (p < 0.05). Considering the relationship between Phe tolerance before and during the pandemic, a significant increase in Phe tolerance was noted during the pandemic in the low Phe diet group (p < 0.05). Conclusions: Telemedicine can be an appropriate and effective monitoring option for PKU patients during the COVID-19 pandemic.

Safety issues associated with dietary management in patients with hepatic glycogen storage disease

INTRODUCTION

Hepatic glycogen storage diseases (GSDs) are a group of inherited disorders of carbohydrate metabolism for which dietary management is the cornerstone. Safety and acute complications associated with dietary management have been poorly documented. We hypothesized that safety issues and complications associated with dietary management are prevalent amongst patients with these ultra-rare disorders.

METHODS

A questionnaire was developed consisting of 40 questions and was distributed via eight GSD patient organizations from multiple countries. Respondents were (caregivers of) patients with self-reported hepatic GSD.

RESULTS

249 GSD patients from 26 countries responded with a median age of 14.8 years (range: 0.5-66.1). Although management was considered safe by 71% of patients, 51% reported at least one acute complication associated with dietary management, with a total number of 425 reported complications. Most frequently reported causes were: not waking up by an alarm clock (n = 70), forgetting a meal (n = 57) and infections (n = 43). Most frequently reported complications were: hypoglycemia (n = 112), hospital admissions (n = 79) and drowsiness (n = 74). Most complications occurred before the age of 12 years (82%; 637/774 total number of reported events) and during night time (63%; 340/536). Only 61% (152/249) of the GSD patients reported using a written emergency protocol.

CONCLUSIONS

Safety issues and complications associated with dietary management are prevalently reported by (caregivers of) 249 GSD patients. A discrepancy has been observed between the patient's perspective on safety of dietary management and occurrence of complications as a result of dietary management.
