Older kidney transplantation candidates' expectations of improvement in life and health following kidney transplantation: semistructured interviews with enlisted dialysis patients aged 65 years and older

Understanding people's decisions when choosing or declining a kidney transplant: a qualitative evidence synthesis

OBJECTIVES

To synthesise qualitative research exploring patients' perspectives, experiences and factors influencing their decision-making preferences when choosing or declining kidney transplantation.

DESIGN

A qualitative evidence synthesis.

DATA SOURCES

Electronic databases were searched from 2000 to June 2021: PubMed, MEDLINE, CINAHL, Embase, PsycINFO, Web of Science, ProQuest Core Databases for Dissertations and Theses, and Google Scholar.

ELIGIBILITY CRITERIA

Qualitative studies exploring and reporting decision-making preferences of people with kidney disease, which reported influencing factors when choosing or declining kidney transplantation, published in English from high-income and middle-income countries.

DATA EXTRACTION AND SYNTHESIS

Titles were screened against the inclusion criteria. Thematic synthesis was done with the use of the Critical Appraisal Skills Programme qualitative checklist to assess study quality, and assessment of confidence in the qualitative findings was done using the Grading of Recommendation, Assessment, Development and Evaluation Confidence in the Evidence from Reviews of Qualitative Research.

FINDINGS

37 studies from 11 countries reported the perspectives of 1366 patients with kidney disease. Six descriptive themes were developed: decisional preferences influenced patients' readiness to pursue kidney transplantation, gathering sufficient information to support decision-making, navigating the kidney transplant assessment pathway, desire for kidney transplantation, opposed to kidney transplantation and uncertainties while waiting for the kidney transplant. A new enhanced theoretical model was developed to aid understanding of the complexities of decision-making in people with kidney disease, by integrating the Theory of Planned Behaviour and the Adaptive Decision Maker Framework to incorporate the novel findings.

CONCLUSION

The synthesis provides a better understanding of the extremely complex decision-making processes of people with kidney disease, which are aligned to their kidney transplantation preferences. Further research is needed to better understand the reasons for declining kidney transplantation, and to underpin development of personalised information, interventions and support for patients to make informed decisions when presented with kidney replacement options.

Adaptation Process After Kidney Transplantation in Older Adult Recipients: Applied Grounded Theory

Despite the increase in older adults receiving kidney transplantation (KT), little is known about their experience and adaptation process after KT. The current study aimed to explore the process of adaptation after KT in older adult recipients using a qualitative design and grounded theory methodology. Sixteen recipients who had KT at age ≥60 years and received follow-up care were recruited at a university hospital in South Korea. Data were collected from July to December 2017 through in-depth interviews with individual participants. The core theme of the adaptation process after KT in older adult recipients was A Journey of Straining to Save the Last Lifeline. The adaptation process comprised three stages: confusion, depression, and compromise. Tailored interventions based on the in-depth understanding of the adaptation process found in the current study are needed to improve adaptation after KT in older adult recipients.

Outcomes of Declined Deceased Donor Kidney Offers That Are Subsequently Implanted: A UK Registry Study

BACKGROUND

Deceased donor kidneys are often declined for ≥1 patients but then implanted into another. Studies are needed to guide transplant clinicians and patients, especially given the increasing age and comorbidity of donors. This study compares outcomes of recipients of transplanted kidneys that were initially declined with outcomes of patients who remained on the waiting list.

METHODS

This UK Transplant Registry study examined named-patient, adult donation after brain death donor single kidney-only offers that were declined for donor- or organ-related reasons (DORRs), in which the kidney was subsequently transplanted from January 1, 2010, to December 31, 2018. Outcomes included graft function and survival of kidneys transplanted following DORR decline, survival and transplant status of patients who had a kidney declined, and intercenter decline rates.

RESULTS

A total of 4722 kidneys declined for DORRs, which eventually resulted in single kidney-only transplants, were examined. One year after the offer decline, 35% of patients for whom the organ was declined remained on the list, 55% received a deceased donor transplant at a median of 174 d after the initial offer decline, and 4% had been removed or died. For patients transplanted following offer decline, there was no significant difference in 5-y graft survival when comparing the outcomes to those recipients who received the declined kidney. There was significant variation in DORR decline rates between UK transplant units (17%-54%).

CONCLUSIONS

This study shows reasonable outcomes of kidneys previously declined for DORRs and supports the utilization of those considered to be of higher risk for carefully selected recipients.

Prevalence of frailty and cognitive impairment in older transplant candidates - a preview to the Kidney Transplantation in Older People (KTOP): impact of frailty on outcomes study

BACKGROUND

Kidney transplantation in older people has increased, however older transplant recipients experience mixed outcomes that invariably impacts on their quality of life. The increased vulnerability of older end stage kidney disease patients to frailty and cognitive impairment, may partially explain the differences in outcomes observed. The Kidney Transplantation in Older People (KTOP): impact of frailty on clinical outcomes study is an active clinical study aiming to explore the experience of older people waiting for and undergoing transplantation. In this manuscript we present the study protocol, the study cohort, and the prevalence of frailty and cognitive impairment identified at recruitment.

METHODS

The KTOP study is a single centre, prospective, mixed methods, observational study. Recruitment began in October 2019. All patients aged 60 or above either active on the deceased donor waitlist or undergoing live donor transplantation were eligible for recruitment. Recruited participants completed a series of questionnaires assessing frailty, cognition, and quality of life, which are repeated at defined time points whilst on the waitlist and post-transplant. Clinical data was concurrently collected. Any participants identified as frail or vulnerable were also eligible for enrolment into the qualitative sub-study.

RESULTS

Two hundred eight participants have been recruited (age 60-78). Baseline Montreal Cognitive Assessments were available for 173 participants, with 63 (36.4%) participants identified as having scores below normal (score < 26). Edmonton Frail Scale assessments were available for 184 participants, with 29 participants (15.8%) identified as frail (score ≥ 8), and a further 37 participants (20.1%) identified as being vulnerable (score 6-7).

CONCLUSION

In the KTOP study cohort we have identified a prevalence of 36.4% of participants with MoCA scores suggestive of cognitive impairment, and a prevalence of frailty of 15.8% at recruitment. A further 20.1% were vulnerable. As formal testing for cognition and frailty is not routinely incorporated into the work up of older people across many units, the presence and significance of these conditions is likely not known. Ultimately the KTOP study will report on how these parameters evolve over time and following a transplant, and describe their impact on quality of life and clinical outcomes.

Kidney transplantation or dialysis in older adults-an interview study on the decision-making process

BACKGROUND

In older patients with end-stage kidney disease (ESKD), the choice between kidney transplantation (KT) and dialysis may be more complex than in younger patients because of a higher prevalence of comorbidities and frailty. This study aims to provide greater insight into the current decision-making process by exploring the expectations, experiences and health outcome priorities of all stakeholders.

METHODS

We performed semi-structured interviews with patients ≥65 years with ESKD (eGFR <15 ml/min/1.73m2, KT recipient or treated with dialysis), patients' relatives and healthcare professionals (nephrologists, nurses and medical social workers). Interviews were conducted until data saturation and thematically analysed.

RESULTS

We performed 36 interviews (patients n = 18, relatives n = 5, healthcare professionals n = 13). Thematic analysis revealed five themes. Older patients' health outcome priorities were mostly related to quality of life (QOL). Individual older patients showed marked differences in the preferred level of engagement during the decision-making process (varying from 'wants to be in the lead' to 'follows the nephrologist') and in informational needs (varying from evidence-based to experience-based). On the contrary, healthcare professionals were quite unanimous on all aspects. They focused on determining eligibility for KT as start of the decision-making process, on clear and extensive information provision and on classical, medical outcomes.

CONCLUSIONS

The decision-making process could benefit from early identification of older patients' values, needs and health outcome priorities, in parallel with assessment of KT eligibility and before discussing the treatment options, and the explicit use of this information in further steps of the decision-making process.

Impact of kidney transplant morbidity on elderly recipients' outcomes

BACKGROUND AND AIMS

Nowadays, advanced age does not represent an absolute contraindication to kidney transplantation (KT). However, aging is frequently associated with multiple comorbidities and lower performance status, making KT candidates less surgically fit. Limited data are available on the impact of KT morbidity on elderly recipients' outcomes.

METHODS

Retrospective study on a single center cohort of 130 KT recipients over 65 years old, representing 16.2% of KT clinical series, during the period 2000-2018. Number and severity of comorbidities were evaluated with the Charlson Comorbidity index (CCI).

RESULTS

The median age at transplantation was 67 [IQR66-71] years and median CCI was 5 [IQR4-6]. The prevalence of postoperative complications with a Clavien-Dindo (C-D) severity score > 2 was 29%. Increasing age did not predict KT morbidity in terms of C-D score > 2, infectious, respiratory, cardiologic, urologic or vascular complications, delayed graft function, symptomatic lymphocele, bleeding, acute or chronic rejection. Conversely, CCI score was a predictor of overall complications with C-D score > 2, cardiologic, respiratory and vascular complications, and bleeding. Among others, CCI score, post-KT cardiologic complications, C-D score > 2 were identified as significant predictors of both early mortality and graft loss in univariate analysis. Increasing recipient age did not correlate with graft loss risk and graft loss did not impact patient survival. C-D score > 2 was a predictor of poor survival even in multivariate analysis.

CONCLUSIONS

Elderly recipients showed a significant vulnerability to KT morbidity which correlates with CCI. While graft loss did not impact recipient survival, severe postoperative complications (C-D > 2) were independently associated increased mortality.
