Cancer QLQ-C30 (EORTC QLQ-C30) [45], the short-from (SF) 36 [46], SF-12 [47], the MD Anderson Symptom Inventory – Lung Cancer [48], the Hospital Anxiety and Depression Scale (HADS) [49], the Functional Assessment of Cancer Therapy-Lung (FACT-L) [50], and the 15D score [51].
Limitations oftheStudies
The timing of postoperative HRQOL follow-up ranged signicantly from 1 month to 7.2 years. The completeness rate of the follow-up ranged signicantly between the studies from 30.0 to 100% and was 75% in 25 (65.7%) studies. The majority of the 38 studies reviewed were obser­vational with only 4 (10.5%) having an element of randomization, of which one (ROSEL) included only 22 patients. The SABR and sub­lobar resection populations often present with multiple co-morbidities which usually exclude them from other approaches. Absence of random­ization has contributed to signicant differences of baseline characteristics between the cohorts. The HRQOL instruments used differed signi­cantly, making it more difcult to compare out­comes between interventions and patient groups.
During the last decade, thoracic surgery has witnessed a rapid development of surgical tech­niques as well as new devices that have helped to improve patient- related outcomes. A signicant number of studies included patients operated
more than 20 years ago, in some cases including techniques and approaches that are out of favour nowadays.
Conclusion
Surgery for NSCLC is performed on a large number of patients of varying age groups and co-morbidities. Summarizing the ndings of the studies included in our chapter (Fig.13.3), it is conrmed that HRQOL outcomes follow­ing lung resection are acceptable. Minimally invasive procedures are associated with an improved physical activity and pain scores. Within the high-risk group of patients who underwent SABR the results remain compara­ble. Sublobar resections have recently been shown to have equivalent survival to lobec­tomy patients [52]and studies comparing these approaches have shown a superiority in terms of physical activity for the lesser resections. We believe it is important to identify factors that can affect the QOL post operatively since it will help both surgeons and patients in their decision- making process especially in the cur­rent era of different therapeutic approaches applicable on lung cancer patients. However, the studies included in this chapter varied sig­nicantly in their follow-up duration and time points of their HRQOL measurements. We sup­port that future randomized studies should include such measurements preoperatively and

Introduction
Transplantation surgery represents one of the greatest achievements in modern medicine. Solid organ transplantation in patients with end-stage organ failure promises not only to extend life but to improve its quality. Nevertheless, the presence of new challenges, such as ageing populations with multiple comorbidities and the organ short­age crisis have the potential to signicantly inu­ence outcomes in transplantation [1]. Furthermore, each patient journey follows a unique course, inuenced by a plethora of biological, psycho­logical, and social variables. These have the capacity to inuence patients’ perception of the value of transplantation. Health- Related Quality of Life (HRQOL) outcomes and Patient-Reported Outcome Measures (PROMs) aim to be tools to capture the unique features of each case and con­fer insights into the ways in which transplantation can affect different groups, allowing us to address new challenges with greater preparedness.
This chapter presents the effects of solid organ
transplantation (kidney, liver, heart, lung) on the

quality of life of recipients and living donors. Studies reporting on pancreas transplantation are included in the section discussing kidney trans­plantation, as most studies report on outcomes for simultaneous kidney-pancreas recipients. A similar approach has been used with regard to small bowel transplantation, which are most commonly performed in the context of combined liver-bowel transplants.
Background
The Role ofHRQOL-PROMS inTransplantation
Elective and emergency operations constitute one of the largest and most resource-demanding ele­ments in healthcare. Therefore, it is essential to optimise the efciency and effectiveness of the associated clinical pathways. QoL outcomes and PROMs can be used to inform quality improve­ment initiatives and improve decision making regarding the allocation of resources and the direction of efforts.
In 2009, the Department of Health in the United Kingdom mandated the inclusion of PROMs as service delivery metrics for certain elective surgical procedures [2]. On a global scale, the International Consortium for Health Outcomes Measurement (ICHOM) has reiter­ated the importance of incorporating PROMS as

tools to measure HRQOL in promoting ‘value­based’ outcome measures and developing inter­national standards of quality assurance in transplantation [3].
In the context of transplantation, monitoring patient progress through clinical criteria or bio­marker reports provides myopic insights into the impact of a disease or treatment on the patient and their quality of life. Formal outcome mea­sures aim to capture the perceived success of transplantation from the patients’ perspective. For instance, patients may report low HRQOL despite a well-functioning graft [4]. In addition, in recent decades, there has been an overall prac­tical and ideological shift in the role of transplan­tation from longevity-oriented outcomes to a tool for transforming HRQOL. Pivotal to this para­digm shift are the organ shortage crisis and the evolving patient demographics, with a rise of older transplant recipients and the increased use of grafts from ‘sub-optimal’ or extended criteria donors [5]. Consequently, HRQOL-PROMS data provide patients with the opportunity to report their symptom-burden and treatment-burden effects. Such insights are invaluable for health-
care systems aiming to foster a patient-centred approach and allowing transplant programmes to evolve and adapt to the needs and demands of patients [6]. Notably, HRQOL and PROMS are different to approaches such as Patient Reported Experience Measures (PREMS) that aim to cap­ture the views of the patients regarding specic elements of service provision (i.e. quality of the hospital facilities, friendliness of the staff) and do not capture patient experience related to a spe­cic therapeutic intervention.
Assessment Tools forMeasuring HRQOL-PROMS inTransplantation
HRQOL-PROMS tools aim to provide an ‘aerial’ view of a patient’s physical, mental and social wellbeing as well as life-participation, through formal assessment tools with validated psycho­metric properties. Such tools can be subdivided into generic (e.g. SF-36, EQ-5D, PROMIS-29 etc.) [79] and disease-specic or symptom spe­cic instruments (e.g. BDI, ESRD-SCL etc.) [10,
11] (Fig.14.1).
Holistic QoL Assessments
•SF-36 (Vitality, physical functioning, bodily pain, general health, physical role functioning, emotional role functioning, social role functioning and mental health)
•SF-12 is a condensed version covering similar domains
• EQ-5D (Mobility, self-care, usual activities, pain/discomfort, anxiety/depression and global health)
• PROMIS-29 (Depression, anxiety, physical function, pain interference, fatigue, sleep disturbance and ability to participate in social roles and activities)
• WHOQOL-100 (Physical, psychological, level of independence, social relationships, environment, spirituality.) etc.
Disease Specific Assessments
• e.g. KTQ, Minnessota Living with Heart Failure Questionnaire, Liver Disease QOL etc.
• Can be used in independently or as adjuncts to generic HRQOL PROMS tools.
Symptom Specific Assesments
• Can report single symptoms e.g. Hospital Anxiety and Depression Score (HADS), Beck Depression

The choice of instrument depends on logisti-
cal factors, such as:
• Time available for completion
• Response burden (the amount of effort or input required from the patient to complete the questionnaire)
• Infrastructure available to implement and interpret questionnaires
• Ability to sustain consistent follow up
• Patient factors (e.g. literacy levels, cognitive function, access to electronic devices etc.)
• Research domains that healthcare profession­als wish to investigate.
Studies may also choose to combine a generic QoL tool and a disease or symptom specic tool to provide both a specic and holistic view of the issue being examined. To achieve the greatest impact, HRQOL should be measured at regular intervals, allowing for identication of trends and clinically meaningful changes in health and/or disease status over time, also known as the ‘responsiveness’ of the instrument [12, 13].
Materials andMethods
transplantation were included. Case reports and review articles were excluded. Articles about ‘autologous transplantation’ and allotransplanta­tion were included. Articles that were not in English were excluded.
Outcomes ofInterest andData Extraction
From each study, the following data was extracted: author, year of publication, data col­lection period, study type, study objectives, sam­ple size, location of study, type of transplant, participant characteristics, evidence of pre­operative HRQOL assessment and follow-up HRQOL, intervals at which HRQOL was mea­sured, HRQOL instrument, completion, non­HRQOL outcomes, main HRQOL ndings and study quality (Table14.1).
Quality Score
The methodological quality of studies was assessed using a standardised 10-item checklist, as reported by Tan etal. [15].
Search Strategy
A systematic search was conducted in August­September 2021 using PubMed, using the fol­lowing search terms: (‘patient-reported outcome measures’ OR ‘patient-reported outcome’) OR (‘quality of life’ OR ‘Health-Related Quality of Life’ OR ‘QoL’ OR ‘HRQOL’) AND (‘transplan­tation’ OR ‘kidney transplant’ OR ‘liver trans­plant’ OR ‘lung transplant’ OR ‘heart transplant’). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were fol­lowed [14, 15].
Inclusion/Exclusion Criteria
There were no limitations set on the type of transplantation, sample size or date of study completion. Articles relating to solid organ

Results
The initial literature search produced 541 results. Based on the inclusion/exclusion criteria, 178 papers were included in the nal analysis (kidney transplantation = 33.7%, liver transplantation =
43.8%, Heart transplantation = 10.7%, Lung transplantation = 11.8%). The total number of patients from all the papers was 44420.
The vast majority of papers were prospective and observational studies (67.6%). From all the papers, a cross-sectional design (64.6%) or a cohort design (32%). A small proportion were randomised controlled trials (2.8%). Quality scores ranged from 2 to 9, with an average score of 7. A pre-operative assessment was only per­formed in 24% of studies.
Most studies used more than one instrument, often combining general and symptom-specic questionnaires. A summary of the different HRQOL instruments encountered in different studies included in this review can be found in Table14.2, and Figs.14.2 and 14.3.
HRQOL andPROMS inKidney Transplantation
Background
Renal transplantation is a catalytic therapeutic intervention in patients with end-stage renal dis­ease (ESRD). Before accessing transplantation, patients are started on renal replacement therapy (RRT) and are placed on the waiting list until an organ is available. The matching process takes into consideration patient characteristics, such as age and comorbidities. However, the non­standardised candidate evaluation criteria are fre­quently centre-specic, resulting in disparities in waiting periods and variable time on RRT.This means that there is signicant variation in the health status and characteristics of transplant candidates. In recent decades, there have been efforts to lower transplantation thresholds and offer grafts to older or medically complex patients. This potentially inuences patient and graft survival, as well as the incidence of hospital readmissions and quality of life outcomes [16].

Overall
• Graft-failure, recommencement of dialysis and re-transplantation do not significantly influence QoL.
•Non-adherence to immunosuppressive regimens is related to poor psychological processing of the transplant.
Symptoms
• ESRD symptoms improve after transplantation but fatigue persists.
• Patients with combined organ transplantation e.g. simultaneous-kidney pancreas and comorbidities such as obesity and diabetes increase the intensity of these symptoms.
•High incidence of anxiety, PTSD, and psychogenic physical health problems e.g. sexual dysfunction, sleep disturbances.
Physical Health
• Low baseline levels of pre-operative fitness, frailty and post-operative steroids predict poor physical health outcomes.
• Lack of physical exercise despite improved exercise tolerance may be related to concerns about graft failure.
•Mental Health
• Female gender, lack of social support and pharmacological management of depression contribute to poor mental health outcomes in ESRD and renal transplant patients.
Social & Employment Outcomes
• Employment is essential to overall QoL. Male recipients achieve better social and employment outcomes.
•Patients who are medically-complex, female or from low-income households are at high risk of poor outcomes.
Donor QoL
•In the long-term, living kidney donors have better QoL than the general population.
• Temporary reduction in QoL immediately after donation due to higher levels of pain and longer recovery time than anticipated, especially amongst female, non-White and middle-aged patients.
• Majority of donors have no regrets about the procedure.
•Paediatric QoL
• Global improvement in physical, mental, educational and social wellbeing.
•Paediatric patients should be encouraged to maintain high levels of physical exercise to maintain physical and mental wellbeing in adulthood.

Overall QoL Outcomes
A summary of the factors affecting HRQOL in kidney transplant patients can be found in Fig. 14.4. Overall, kidney transplantation improves the physical health and tness out­comes. There is mixed evidence about the QoL outcomes of renal transplant recipients compared to those of the general population an compared to other solid organ transplant recipients [1719]. This may be due an emphasis on clinical postop­erative outcomes and end-points such as cessation of dialysis, as well as biomarker criteria e.g. reduction in creatinine, rather than QoL outcomes
and post-operative support [18, 19]. Furthermore, adverse transplant outcomes, such as graft failure, leading to re-commencement of dialysis or RRT does not lead to a signicant reduction in QoL compared to the pre-transplant status, as these patients scored similarly to patients not previ­ously transplanted [18, 19]. Post-transplant fac­tors that inuence QoL include medication non-adherence and the presence of medical com­plications or critical illness [20]. In addition, problematic psychological processing of the life­changing transplant event is a risk factor for non­adherence to post-transplant regimens [21].
