Development and Validation of Models to Predict Poor Health-Related Quality of Life Among Adult Survivors of Childhood Cancer

Risk prediction models are important to identify survivors of childhood cancer who are at risk of experiencing poor health-related quality of life (HRQOL) as they age. To develop and validate prediction models for a decline in HRQOL among adult survivors of childhood cancer. This prognostic study included 4755 adults from the Childhood Cancer Survivor Study (CCSS) diagnosed between January 5, 1970, and December 31, 1986, who completed baseline (time 0 [November 3, 1992, to August 28, 2003]) and 2 follow-up (time 1 [February 12, 2002, to May 21, 2005] and time 2 [January 6, 2014, to November 30, 2016]) surveys. Data were analyzed from June 19, 2019, to February 2, 2022. Sociodemographic, lifestyle, and emotional factors, and chronic health conditions (CHCs) were assessed at time 0 and time 1, and neurocognitive factors were assessed at time 1 to predict HRQOL at time 2 and a decline in HRQOL between time 1 and time 2. Impaired health states were defined as CHC grades 2 to 4 using the modified Common Terminology Criteria for Adverse Events, version 4.03, and mental and neurocognitive status as 1 SD or more below reference levels. Health-related quality of life was operationalized using the Medical Outcomes Study 36-Item Short Form Health Survey Physical (PCS) and Mental (MCS) Component Summary and classified by optimal (≥40) or suboptimal (<40) at each point (main outcome). A decline in HRQOL was defined as a change from optimal to suboptimal between time 1 and time 2. Multivariable logistic regression identified factors associated with HRQOL decline. The cohort was randomly split into training (80%) and test (20%) data sets for model development and validation; the area under the receiver operating characteristic curve was used to evaluate prediction performance. A total of 4755 adults (mean [SD] age at time 0, 24.3 [7.6] years; 2623 [55.2%] women) were included in the analysis. Between time 1 and time 2, 285 of 3294 survivors (8.7%) had declining PCS and 278 of 3294 (8.4%) had declining MCS. Risk factors associated with PCS decline included female sex (odds ratio [OR], 1.67 [95% CI, 1.25-2.24]), family income less than $20 000 vs $80 000 or more (OR, 2.00 [95% CI, 1.21-3.30]), presence of CHCs (OR for neurological, 2.16 [95% CI, 1.51-3.10]; OR for endocrine, 2.25 [95% CI, 1.44-3.52]; OR for gastrointestinal tract, 1.89 [95% CI, 1.32-2.69]; OR for respiratory, 1.66 [95% CI, 1.06-2.59]; OR for cardiovascular, 1.53 [95% CI, 1.14-2.06]), and depression (OR, 1.79 [95% CI, 1.20-2.67]). Risk factors associated with MCS decline included unemployment vs full-time employment (OR, 1.68; [95% CI, 1.19-2.38]), current vs never cigarette smoking (OR, 2.03 [95% CI, 1.37-3.00]), depression (OR, 4.29 [95% CI, 2.44-7.55]), somatization (OR, 1.63 [95% CI, 1.05-2.53]), impaired task efficiency (OR, 1.90 [95% CI, 1.34-2.68]), and impaired organization (OR, 1.67 [95% CI, 1.12-2.48]). The areas under the receiver operating characteristic curve for the test models were 0.74 (95% CI, 0.67-0.81) for declining PCS and 0.68 (95% CI, 0.60-0.75) for declining MCS. In this prognostic study of adult survivors of childhood cancer who experienced declining HRQOL, CHCs were associated with a decline in physical HRQOL, whereas current smoking and emotional and neurocognitive impairment were associated with a decline in mental HRQOL. These findings suggest that interventions targeting modifiable risk factors are needed to prevent poor HRQOL in this population.

Health-Related Quality of Life according to Renal Function: Results from a Nationwide Health Interview and Examination Survey

Background: Most studies on health-related quality of life (HRQoL) in chronic kidney disease (CKD) focus on patients with end-stage kidney disease although they represent a small proportion of patients with CKD. We aimed to analyze HRQoL according to glomerular filtration rate (GFR) categories in a population-based sample of adults living in Germany. Methods: Data from the German health interview and examination survey conducted from 2008 to 2011 were used. Participants with valid interview and examination data aged 40–79 years were included (n = 5,159). Serum creatinine levels were used to calculate estimated GFR via the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. We classified kidney function in GFR categories according to the Kidney Disease Improving Global Outcomes Initiative (KDIGO) guidelines on CKD: G1 (high): ≥90 mL/min/1.73 m², G2 (normal): 60–89 mL/min/1.73 m², G3a (mildly decreased): 45–59 mL/min/1.73 m², G3b (moderately decreased): 30–44 mL/min/1.73 m², G4/5 (severely decreased/end-stage kidney disease): <30 mL/min/1.73 m². HRQoL was evaluated with the Short Form Health Survey (SF-36). Different multivariate linear and logistic regression models were used to analyze the association of HRQoL with GFR categories. Results: Overall, 5.9% had a GFR <60 mL/min/1.73 m² (corresponding to categories G3a, G3b, and G4/5). Compared to category G2 linear regression showed a decline in physical HRQoL in categories G3a (−2.34, p = 0.004), G3b (−5.37, p = 0.009), and G4/5 (−4.82, p = 0.117). No decline in mental HRQoL was detected with increasing GFR categories. Categories G3a to G4/5 were significantly associated with a low perceived general state of health (G3a: odds ratio [OR] = 2.03, p = 0.001; G3b: OR = 3.01, p = 0.009; G4/5: OR = 8.70, p = 0.016) when compared to category G2. Conclusion: In a representative sample of adults living in Germany, both physical HRQoL and the perceived general state of health are already significantly reduced in category G3a.

Medication Adherence, Burden and Health-Related Quality of Life in Adults with Predialysis Chronic Kidney Disease: A Prospective Cohort Study.

This study examines the associations between medication adherence and burden, and health-related quality of life (HRQOL) in predialysis chronic kidney disease (CKD). A prospective study targeting adults with advanced CKD (estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m2) and not receiving renal replacement therapy was conducted in Tasmania, Australia. The actual medication burden was assessed using the 65-item Medication Regimen Complexity Index, whereas perceived burden was self-reported using a brief validated questionnaire. Medication adherence was assessed using a four-item Morisky-Green-Levine Scale (MGLS) and the Tool for Adherence Behaviour Screening (TABS). The Kidney Disease and Quality of Life Short-Form was used to assess HRQOL. Of 464 eligible adults, 101 participated in the baseline interview and 63 completed a follow-up interview at around 14 months. Participants were predominantly men (67%), with a mean age of 72 (SD 11) years and eGFR of 21 (SD 6) mL/min/1.73 m2. Overall, 43% and 60% of participants reported medication nonadherence based on MGLS and TABS, respectively. Higher perceived medication burden and desire for decision-making were associated with nonadherent behaviour. Poorer HRQOL was associated with higher regimen complexity, whereas nonadherence was associated with a decline in physical HRQOL over time. Medication nonadherence, driven by perceived medication burden, was prevalent in this cohort, and was associated with a decline in physical HRQOL over time.

The Relationship Between Chronic Kidney Disease, Symptoms and Health-Related Quality of Life: A Systematic Review.

People with chronic kidney disease (CKD) experience a wide range of symptoms due to reduced kidney function. As the disease progresses these symptoms become more burdensome and often negatively affect a person's health-related quality of life (HRQoL). To examine the evidence of symptoms and HRQoL in CKD stages 1-5 and the relationships between these. Studies published in English from January 2008 to July 2018 using six databases (PubMed, MEDLINE, CINAHL, PsycINFO, Cochrane Library and JBI Library) were searched. Thirteen studies were included in this review although only three had interventional designs. By considering symptom experience and HRQoL together, four studies found that HRQoL decreased when symptoms increased. Feeling washed out, fatigue and drowsiness were found to be the most common symptoms reported. Only two studies reported follow-up measurements although six studied how symptoms change over time. None of the studies examined the change of symptoms over time across the different CKD stages. The majority of studies showed a decline in physical HRQoL and improvement in mental HRQoL over time. Nutritional and exercise interventions showed some improvements in symptom experience and HRQoL. Only four studies were found that reported the relationship between symptoms and HRQoL of those with CKD. Of these, in view of symptom experience and HRQoL together, HRQoL decreased when symptoms increased. However, more research is warranted to establish a clear understanding of the relationship between symptoms and HRQoL in CKD to enable the design of appropriate interventions.

Patient-Reported Quality of Life Is an Independent Predictor of Survival after Allogeneic Hematopoietic Cell Transplantation: A Secondary Analysis from the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0902

INTRODUCTIONPatient reported outcomes (PROs) including symptoms and health related quality of life (HRQOL) predict mortality in multiple cancers, such as myeloma, head and neck, lung and prostate cancer. The relationship of PROs with survival is not clear in hematopoietic cell transplantation (HCT). We tested three hypotheses about the relationship between HRQOL and survival after HCT: (1) Pre-HCT HRQOL (particularly physical HRQOL) reflects functional status and predicts survival after allogeneic (allo) HCT independently of traditional risk factors and indices; (2) Post-HCT change in physical HRQOL reflects the “toll” of the HCT and predicts subsequent outcomes, including survival, among early survivors; (3) Since autologous (auto) HCT is associated with lower risks for treatment-related morbidity and mortality, PROs may not be as predictive for this group. METHODSWe tested these hypotheses using data from the 711 participants in BMT CTN 0902 (sponsored by NHLBI and NCI, NCT 01278927), a randomized study of pre-transplant exercise and stress management training for patients undergoing auto or allo HCT. Because the primary analysis for BMT CTN 0902 did not show a significant effect for exercise or stress management training, intervention groups were combined for these analyses. However, auto and allo recipients were analyzed separately because of the expected substantial differences in the subsequent risks for morbidity and mortality in the two populations. The HRQOL measures used were the physical component score (PCS) and mental component score (MCS) from the SF-36, measured pre-HCT and at day 100. RESULTSAmong 310 alloHCT recipients with a median follow-up of 23 months, while there were no pre-HCT clinical covariates (including age, conditioning intensity, donor type, graft source, disease, disease stage) that predicted survival, pre-HCT physical HRQOL (PCS on the SF-36) was strongly prognostic for survival (HR for death of 0.72 per 10 points increase, 95% CI 0.60-0.85, p<0.001) while pre-HCT MCS was not (HR 0.99, 95% CI 0.84-1.16, p=0.29). Survival estimates for the first, second, third, and fourth quartiles of baseline PCS were, respectively, 67%, 72%, 81%, and 91% at 6 months and 50%, 65%, 75%, and 83% at one year (Figure 1). Among the eight SF-36 subscales, higher pre-HCT Physical Functioning and General Health scores were strongly associated with better survival. Among day 100 survivors, the PCS change score from baseline to Day 100 was also strongly prognostic for subsequent survival after adjusting for pre-HCT PCS (HR 0.55 per 10 points improvement, 95% CI 0.42-0.72, p<0.001) as was the MCS change score after adjusting for pre-HCT MCS (HR 0.70, 95% CI 0.56-0.89, p=0.003). In models that included patient age and the Hematopoietic Cell Transplantation-specific Comorbidity Index (HCT-CI), the EBMT Score, or the Disease Risk Index (DRI), the findings for both pre-HCT values and change scores remained statistically significant with similar hazard ratios, suggesting that PROs convey independent prognostic information for survival despite inclusion of traditional risk factors. Analyses of transplant-related mortality (TRM) in alloHCT recipients showed similar patterns. Higher pre-HCT PCS was predictive of lower TRM. Among patients alive and disease-free at day 100, PCS change score was also associated with lower TRM after adjusting for pre-HCT PCS (HR 0.28, 95% CI 0.17-0.47, p<0.001) and the HCT-CI, EBMT and DRI; pre-HCT MCS and change in MCS did not predict TRM. Among autoHCT recipients (n=337), there were no pre-HCT clinical covariates that predicted survival. Pre-HCT HRQOL also was not prognostic of survival in autoHCT (physical PCS from the SF-36 p=0.82, mental MCS from the SF-36, p=0.56), nor were early changes in either the PCS or the MCS. CONCLUSIONIn summary, among alloHCT recipients who participated in BMT CTN 0902, lower pre-HCT physical HRQOL and early decline in physical HRQOL were strongly predictive for worse overall survival and higher transplant-related mortality. These results suggest that patient-reported data are an important component of risk assessment and could assist in clinical decision-making. High-risk individuals could be targeted for different management strategies or more aggressive supportive care interventions to reduce treatment-related morbidity and mortality in this population.

Change in the Health-Related Quality of Life of Multiple Sclerosis Patients over 5 Years

This study examined whether multiple sclerosis (MS) patients (N = 3779) experience change in their perceived health-related quality of life (HRQOL) over a 5-year period, and investigated baseline factors that may be related to change in HRQOL. Data from the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry were used to address the study's research questions. Results for the physical and mental component scores of the 12-item Short Form Health Status Survey, version 2 (SF-12v2), indicated that most of the MS sample experienced no significant changes over a 5-year period. However, 40% and 36% of the sample experienced clinically significant declines in their physical and mental HRQOL, respectively, over the 5-year period. After controlling for baseline scores, having a lower education, having greater duration since disease diagnosis, not being employed, having a lower income, not receiving a disease-modifying therapy, and taking a greater number of prescription medications were significantly associated with a clinically significant decline in physical HRQOL. After controlling for baseline scores, not being married/partnered, experiencing a greater number of relapses, not being employed, having a lower income, and taking a greater number of prescription medications were significantly associated with a clinically significant decline in mental HRQOL. Overall, most of the MS sample remained stable in their HRQOL over time. However, approximately four out of every ten patients experienced a clinically important decline in their HRQOL. While the association was statistically significant, the sociodemographic and disease-related factors linked with decline did not strongly predict decline over a 5-year period.
