Evaluating the TUITEK® patient support program in supporting caregivers of children diagnosed with growth hormone deficiency in Argentina.

Introduction: The appropriate use of recombinant human growth hormone (r-hGH) treatment provides an opportunity to improve growth outcomes among pediatric patients with growth hormone deficiency (GHD). However, a major challenge in clinical practice is to adequately recognize and address factors that negatively affect treatment adherence. TUITEK® patient support program (PSP) was designed to help caregivers of children diagnosed with GHD to personalize the care pathway, improve adherence, and achieve better outcomes. Effectiveness of TUITEK® PSP has been demonstrated previously in a smaller sample (n = 31) in Taiwanese population. Here, we present the results from Argentina. Methods: TUITEK® PSP was piloted among 76 caregivers of children with GHD administering r-hGH using easypod™ (Merck KGaA, Darmstadt, Germany) auto-injector device in Argentina. Based on TUITEK® personalization questionnaire, caregivers were assigned to high- and low-risk groups across four categories that may influence adherence, including disease and treatment coherence (DTC), self-administration (SA), treatment-related anxiety (TRA), and emotional burden (EB). The caregivers who were included in atleast one high-risk group had the provision of telephone calls with a nurse practitioner every 2 weeks for 3 months. The Wilcoxon signed-rank test was employed to assess changes in questionnaire-based scoring patterns between baseline and follow-up evaluations. Results: Statistically significant changes (p < 0.05) in questionnaire scores between baseline and follow-up evaluations were observed across the four categories. The mean/median DTC (n = 11) and SA (n = 23) scores changed from 2.45/3 and 2.17/2, respectively, to 4/4, with all the caregivers moving to low-risk group following program completion (100%) for both categories. The mean/median TRA score (n = 40) changed from 3.58/3 to 2.5/2 and 67.5% of patients (27/40) moved to low-risk group. The mean/median EB score (n = 32) changed from 3.69/3 to 3.13/3 however, none of the caregivers moved to low-risk group (0%). Conclusion: TUITEK® PSP is a simple, practical, and time-efficient interventional tool that can be used to address key adherence-related issues among caregivers of children with GHD and provide personalized adherence support. Our findings demonstrate that TUITEK® PSP has the potential to improve treatment adherence and self-management, thereby improving growth outcomes in Argentina.

Designing a Personalized Digital Patient Support Program for Patients Treated With Growth Hormone: Key Design Considerations.

BACKGROUND: Recombinant human growth hormone treatment can optimize growth potential; however, optimal outcomes are not always achieved for several reasons, including poor adherence. The overall objective of this project was to design a patient support program to maximize the chances of treatment success for people being treated with somatropin injection. An approach known as the behavior change wheel was used to enhance the development of the patient support program. The behavior change wheel provided a comprehensive framework to support the design of interventions. OBJECTIVE: The aim of this paper was to describe how the steps of the behavior change wheel were applied to the development of a patient support program for individuals with growth hormone deficiency undergoing treatment with somatropin. METHODS: We followed a series of steps that align to tenets of the behavior change wheel, namely, a narrative literature review to identify which behaviors needed to change and the potential drivers of and barriers to the behaviors, the selection of an intervention strategy and discrete behavior change techniques, and, finally, intervention specification. RESULTS: A recent systematic review identified a range of potentially modifiable factors found to have an influence on patient adherence to growth hormone treatment. Insights from the systematic review were used to guide the development of a patient support program. The final design of the patient support program consisted of four elements: (1) a personalization questionnaire to tailor support for each individual, (2) tailored reminder and support SMS text messages, (3) nurse-led phone calls, and (4) Easypod connect, an automated electronic autoinjector drug-delivery device with a transmitter and connection platform for Saizen (somatropin) that allows automatic recording, storage, and transmission of drug-usage data, thus providing insight into suboptimal adherence. CONCLUSIONS: The patient support program that was designed is currently being piloted with patients to assess engagement with the program and determine its impact on patient outcomes. Results from the pilot will be used to further refine the program to ensure it meets user needs.

You cannot choose your family: sociological ambivalence in the hemodialysis unit.

Living with end-stage renal disease is challenging and requires a great deal of self-management, but little is known about the experiences of patients and staff around the subject. We held six focus groups in three hemodialysis units, each unit hosting 1 staff and 1 patient focus group. A total of 15 staff members and 15 patients participated. We employed thematic analysis using a priori and emerging codes. Five key themes emerged: challenges, enablers, complex balancing acts, good patient/bad patient, and the hemodialysis unit as a family. We explored the family metaphor further through the work of Bourdieu, but concluded that relationships in the hemodialysis unit most closely fit the concept of sociological ambivalence. We present an explanatory framework around inherent tensions characterizing relationships within the hemodialysis unit and highlight implications for facilitating self-management and developing collaborative approaches to care.

Commercial software upgrades may significantly alter Perfusion CT parameter values in colorectal cancer.

OBJECTIVE: To determine how commercial software platform upgrades impact on derived parameters for colorectal cancer. MATERIALS AND METHODS: Following ethical approval, 30 patients with suspected colorectal cancer underwent Perfusion CT using integrated 64 detector PET/CT before surgery. Analysis was performed using software based on modified distributed parameter analysis (Perfusion software version 4; Perfusion 4.0), then repeated using the previous version (Perfusion software version 3; Perfusion 3.0). Tumour blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability surface area product (PS) were determined for identical regions-of-interest. Slice-by-slice and 'whole tumour' variance was assessed by Bland-Altman analysis. RESULTS: Mean BF, BV and PS was 20.4%, 59.5%, and 106% higher, and MTT 14.3% shorter for Perfusion 4.0 than Perfusion 3.0. The mean difference (95% limits of agreement) were +13.5 (-44.9 to 72.0), +2.61 (-0.06 to 5.28), -1.23 (-6.83 to 4.36), and +14.2 (-4.43 to 32.8) for BF, BV, MTT and PS respectively. Within subject coefficient of variation was 36.6%, 38.0%, 27.4% and 60.6% for BF, BV, MTT and PS respectively indicating moderate to poor agreement. CONCLUSION: Software version upgrades of the same software platform may result in significantly different parameter values, requiring adjustments for cross-version comparison.
