Changes in quality of life, health status and other patient‐reported outcomes following simultaneous pancreas and kidney transplantation (SPKT): a quantitative and qualitative analysis within a UK‐wide programme

Assessing quality of life in solid organ transplant recipients: A systematic review of the development, content, and quality of available condition- and transplant-specific patient-reported outcome measures

PURPOSE

We aimed to identify the condition- and transplant-specific patient-reported outcome measures (PROMs) available to measure quality of life (QoL) in solid organ transplant (SOT) recipients, examine their development and content, and critically appraise the quality of their measurement properties, to inform recommendations for clinical and research use.

METHODS

We systematically searched MEDLINE, Embase, CINAHL, PsycINFO, Cochrane CENTRAL, and Scopus from inception to 27th January 2023. Search hits were screened for eligibility by two independent reviewers; papers reporting the development and/or validation of condition- and transplant-specific PROMs measuring QoL in adult SOT recipients were considered eligible. We abstracted and synthesised data on PROM characteristics, development (item generation and/or reduction), and content (QoL dimensions). Quality appraisal and synthesis were informed by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines, and included methodological and quality assessment of measurement properties, GRADE levels of evidence, feasibility and interpretability.

RESULTS

We identified 33 papers reporting 26 QoL PROMs validated in SOT recipients (kidney n = 10 PROMs; liver n = 6; lung n = 3; heart n = 2; pancreas n = 1; multiple organs n = 4). Patient discussions (n = 17 PROMs) and factor analysis (n = 11) were the most common item generation and reduction techniques used, respectively. All PROMs measured ≥3 of nine QoL dimensions (all measured emotional functioning); KDQoL-SF and NIDDK-QA measured all nine. Methodological quality was variable; no PROM had low evidence or better for all measurement properties. All PROMs were COSMIN recommendation category 'B', primarily because none had sufficient content validity.

CONCLUSIONS

There are many condition- and transplant-specific QoL PROMs validated in SOT recipients, particularly kidney. These findings can help inform PROM selection for clinicians and researchers. However, caution is required when adopting measures, due to the substantial heterogeneity in development, content, and quality. Each PROM has potential but requires further research to be recommendable. Greater consideration of patient and professional involvement in PROM development in this setting is needed to ensure sufficient content validity.

Effects of a Phone-Based Support Program for Women With Breast Cancer Undergoing Chemotherapy: A Pilot Study

Introduction

The increasing number of women with breast cancer undergoing chemotherapy may result in long-lasting, adverse physical side effects and reduced quality of life.

Objective

This study aimed to develop and assess the feasibility and preliminary effects of the Phone-Based Support Program for women with breast cancer undergoing chemotherapy. The primary outcome was self-care self-efficacy; secondary outcomes were symptom distress and quality of life.

Methods

This pilot study was conducted at a tertiary hospital in Jiangsu province, China, from February to March 2023. The Phone-Based Support Program was delivered to 20 participants through the smartphone application WeChat, consisting of learning, discussion, ask-the-expert, and personal stories components. Outcome measures were assessed at three time points: preintervention, postintervention, and follow-up.

Results

The Phone-Based Support Program was feasible and could improve self-care self-efficacy, decrease symptom distress, and promote quality of life. The program was well-accepted, and participants engaged actively in the online discussion and sought expert advice.

Conclusions

The Phone-Based Support Program showed feasibility and effectiveness in improving self-care self-efficacy, reducing symptom distress, and enhancing quality of life.

Novel Endpoints in Solid Organ Transplantation: Targeting Patient-reported Outcome Measures

Although solid organ transplantation improves survival and quality of life in many patients with organ failure, treatment complications and side effects can have debilitating consequences for patients. Patient-reported outcome measures (PROMs) capture how patients feel and function, including quality of life, symptoms, and side effects that are assessed directly by patients. Yet, they remain infrequently reported in trials in solid organ transplantation. Barriers to implementing PROMs in trials include uncertainty in selecting appropriate PROMs, concerns about resources limitations, patient burden, and limited evidence to support the psychometric robustness of measures for use in transplant recipients. In recent years, there have been increasing efforts to include patient-reported outcomes that are important to patients in trials to ensure that trials provide patient-centered information for decision-making. This article will provide an overview of PROMs, discuss PROs that are important to solid organ transplant recipients and those that are used in trials in solid organ transplantation, and outline approaches for selecting PROMs for clinical trials.

Psychological care of patients during the pancreas transplantation process: issues and prospects

Pancreas transplantation for patients with type 1 diabetes is a therapeutic option when other treatments are not effective and physical complications occur. Psychological burden is prominent in patients, and non-adherence to treatment is often one manifestation of such difficulties. Time projection is an important factor affected by chronic disease. The prospect of transplantation has the potential to repair this disruption. It could re-establish a continuity in the patient's self and history, by connecting the future to a life that was only about past and present. Taking care of oneself, adhering to treatment, being part of a long-term therapeutic project and going through transplantation are all processes that need a good ability to self-project in time. This is specifically a domain of psychotherapeutic interventions. In this article, the psychological implications of pancreas transplantation for patients and caregivers alike will be discussed, as well as the role of the psychiatrist in the transplantation process.

Pancreas Transplantation: Current Challenges, Considerations, and Controversies

Pancreas transplantation (PTx) reestablishes an autoregulating source of endogenous insulin responsive to normal feedback controls. In addition to achieving complete β-cell replacement that frees the patient with diabetes from the need to monitor serum glucose and administer exogenous insulin, successful PTx provides counterregulatory hormone secretion and exocrine function. A functioning PTx mitigates glycemic variability, eliminates the daily stigma and burden of diabetes, restores normal glucose homeostasis in patients with complicated diabetes, and improves quality of life and life expectancy. The tradeoff is that it entails a major surgical procedure and requisite long-term immunosuppression. Despite the high likelihood of rendering patients euglycemic independent of exogenous insulin, PTx is considered a treatment rather than a cure. In spite of steadily improving outcomes in each successive era coupled with expansion of recipient selection criteria to include patients with a type 2 diabetes phenotype, a decline in PTx activity has occurred in the new millennium related to a number of factors including: (1) lack of a primary referral source and general acceptance by the diabetes care community; (2) absence of consensus criteria; and (3) access, education, and resource issues within the transplant community. In the author's experience, patients who present as potential candidates for PTx have felt as though they needed to circumvent the conventional diabetes care model to gain access to transplant options. PTx should be featured more prominently in the management algorithms for patients with insulin requiring diabetes who are failing exogenous insulin therapy or experiencing progressive diabetic complications regardless of diabetes type. Furthermore, all patients with diabetes and chronic kidney disease should undergo consideration for simultaneous pancreas-kidney transplantation independent of geography or location.

Modern indications for referral for kidney and pancreas transplantation

PURPOSE OF REVIEW

Pancreas transplantation (PTx) is currently the only therapy that can predictably achieve sustained euglycemia independent of exogenous insulin administration in patients with insulin-dependent diabetes mellitus. This procedure involves a complex abdominal operation and lifetime dependence on immunosuppressive medications. Therefore, PTx is most frequently performed in combination with other organs, usually a kidney transplant for end stage diabetic nephropathy. Less frequently, solitary PTx may be indicated in patients with potentially life-threatening complications of diabetes mellitus. There remains confusion and misperceptions regarding indications and timing of patient referral for PTx.

RECENT FINDINGS

In this review, the referral, evaluation, and listing process for PTx is described, including a detailed discussion of candidate assessment, indications, contraindications, and outcomes.

SUMMARY

Because the progression of diabetic kidney disease may be less predictable than other forms of kidney failure, early referral for planning of renal and/or pancreas transplantation is paramount to optimize patient care and allow for possible preemptive transplantation.

Pancreas Transplantation in Minorities including Patients with a Type 2 Diabetes Phenotype

Background: Prior to year 2000, the majority of pancreas transplants (PTx) were performed as simultaneous pancreas-kidney transplants (SPKTs) in Caucasian adults with end stage renal failure secondary to type 1 diabetes mellitus (T1DM) who were middle-aged. In the new millennium, improving outcomes have led to expanded recipient selection that includes patients with a type 2 diabetes mellitus (T2DM) phenotype, which excessively affects minority populations. Methods: Using PubMed® to identify appropriate citations, we performed a literature review of PTx in minorities and in patients with a T2DM phenotype. Results: Mid-term outcomes with SPKT in patients with uremia and circulating C-peptide levels (T2DMphenotype) are comparable to those patients with T1DM although there may exist a selection bias in the former group. Excellent outcomes with SPKT suggests that the pathophysiology of T2DM is heterogeneous with elements consisting of both insulin deficiency and resistance related to beta-cell failure. As a result, increasing endogenous insulin (Cp) production following PTx may lead to freedom checking blood sugars or taking insulin, better metabolic counter-regulation, and improvements in quality of life and life expectancy compared to other available treatment options. Experience with solitary PTx for T2DM or in minorities is limited but largely mirrors the trends reported in SPKT. Conclusions: PTx is a viable treatment option in patients with pancreas endocrine failure who are selected appropriately regardless of diabetes type or recipient race. This review will summarize data that unconventional patient populations with insulin-requiring diabetes may gain value from PTx with an emphasis on contemporary experiences and appropriate selection in minorities in the new millennium.

Patient Experience in Pancreas-Kidney Transplantation-A Methodological Approach Towards Innovation in an Established Program

Simultaneous pancreas-kidney transplantation (SPKT) leads to increased survival and quality of life, and is an alternative treatment for insulin-dependent diabetes mellitus and end-stage kidney disease. Due to the particularities of this population (often with multiple comorbidities) and of the surgery (only performed in a few centers), a comprehensive analysis of patients' experience along the SPKT process is crucial to improve patient care and add value to this procedure. Therefore, we applied a systematic and iterative methodology with the participation of both patients and professional teams working together to explore and identify unmet needs and value-adding steps along the transplant patient journey at an established pancreas transplant program. Four main steps (to comprehend, to explore, to experiment and to assess) led to several interventions around three major areas: Administration and logistics, information and communication, and perceived quality of assistance. As a result, both displacements to the hospital for diagnostic purposes and the time delay involved in joining the patient waiting list for transplantation were reduced in parallel to the administrative procedures. In conclusion, the methodological implementation of key organizational changes has great impact on overall patient experience. Further quantitative analysis from the patient's perspective will consolidate our program and may add new prototype service design components.

Perspectives of solid organ transplant recipients on medicine-taking: Systematic review of qualitative studies

Medicine-taking among transplant recipients is a complex and ubiquitous task with significant impacts on outcomes. This study aimed to describe the perspectives and experiences of medicine-taking in adult solid organ transplant recipients. Electronic databases were searched to July 2020, and thematic synthesis was used to analyze the data. From 119 studies (n = 2901), we identified six themes: threats to identity and ambitions (impaired self-image, restricting goals and roles, loss of financial independence); navigating through uncertainty and distrust (lacking tangible/perceptible benefits, unprepared for side effects, isolation in decision-making); alleviating treatment burdens (establishing and mastering routines, counteracting side effects, preparing for the unexpected); gaining and seeking confidence (clarity with knowledge, reassurance through collective experiences, focusing on the future outlook); recalibrating to a new normal posttransplant (adjusting to ongoing dependence on medications, in both states of illness and health, unfulfilled expectations); and preserving graft survival (maintaining the ability to participate in life, avoiding rejection, enacting a social responsibility of giving back). Transplant recipients take medications to preserve graft function, but dependence on medications jeopardizes their sense of normality. Interventions supporting the adaptation to medicine-taking and addressing treatment burdens may improve patient satisfaction and capacities to take medications for improved outcomes.

Transplant Options for Patients With Diabetes and Advanced Kidney Disease: A Review

Optimal glycemic control in kidney transplant recipients with diabetes is associated with improved morbidity and better patient and allograft survival. Transplant options for patients with diabetes requiring insulin therapy and chronic kidney disease who are suitable candidates for kidney transplantation should include consideration of β-cell replacement therapy: pancreas or islet transplantation. International variation related to national regulatory policies exists in offering one or both options to suitable candidates and is further affected by pancreas/islet allocation policies and transplant waiting list dynamics. The selection of appropriate candidates depends on patient age, coexistent morbidities, the timing of referral to the transplant center (predialysis versus on dialysis) and availability of living kidney donors. Therefore, early referral (estimated glomerular filtration rate < 30 mL/min/1.73 m²) is of the utmost importance to ensure adequate time for informed decision making and thorough pretransplant evaluation. Obesity, cardiovascular disease, peripheral vascular disease, smoking, and frailty are some of the conditions that need to be addressed before acceptance on the transplant list, and ideally before dialysis becoming imminent. This review offers insights into selection of pancreas/islet transplant candidates by transplant centers and an update on posttransplant outcomes, which may have practice implications for referring nephrologists.
