The impact of adverse events on health-related quality of life among patients receiving treatment for drug-resistant tuberculosis in Johannesburg, South Africa

BACKGROUND

Adverse events (AEs) are common during treatment of drug-resistant tuberculosis (DR-TB). Little is known about the health-related quality of life (HRQoL) of patients receiving treatment for DR-TB or the effect of AEs on HRQoL.

METHODS

We conducted a cross-sectional study among adult patients with laboratory-confirmed rifampicin resistant tuberculosis (TB) on DR-TB treatment at a public-sector outpatient DR-TB clinic in Johannesburg, South Africa between 02/2015-01/2018. Data on HRQoL using the Medical Outcomes Short Form-36 (SF-36) questionnaire and self-reported AEs were collected by trained interviewers through face-to-face interviews. We report averages for the eight major domains and mental (MCS) and physical health (PCS) component summary scores, stratified by whether AEs were reported in the last four weeks. For comparative purposes, we enrolled two other patient groups and included data on a separate group of healthy adults.

RESULTS

We enrolled 149 DR-TB patients (median age 36 years IQR 29-43, 55% male, 77.9% HIV-positive, 81% on ART, 61.8% on a standard long-course regimen and 44.3% on DR-TB treatment for less than 6 months). 58/149 (38.9%) patients reported a total of 122 AEs in the preceding 4 weeks, of these the most common were joint pain (n = 22), peripheral neuropathy (n = 16), hearing loss (n = 15), nausea and vomiting (n = 12) and dizziness or vertigo (n = 11). SF-36 domains and summary scores (MCS and PCS) were lower in those who reported an AE compared to those who did not, and both were lower than healthy adults. Compared to those who did not report an AE, patients who reported AEs were more likely to have a low MCS (aRR 2.24 95% CI 1.53-3.27) and PCS (aRR 1.52 95% CI 1.07-2.18) summary score. HRQoL was lower among those on DR-TB treatment for 6 months or less.

CONCLUSION

Results show that DR-TB had a substantial impact on patients' quality of life, but that AEs during the early months on treatment may be responsible for reducing HRQoL even further. Our findings highlight the negative effects of injectable agents on HRQoL. Patients require an integrative patient-centered approach to deal with DR-TB and HIV and the potential overlapping toxicities which may be worsened by concurrent treatment.

Health-related quality of life after interval cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with stage III ovarian cancer

INTRODUCTION

The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery (CRS) improves recurrence-free (RFS) and overall survival (OS) in patients with FIGO stage III ovarian cancer. We evaluated the effect of HIPEC on patient's health-related quality of life (HRQoL) in the OVHIPEC trial.

MATERIALS AND METHODS

OVHIPEC was a multicentre, open-label, randomized phase III trial for patients with stage III ovarian cancer. Patients were randomly assigned (1:1) to receive interval CRS with or without HIPEC with cisplatin. HRQoL was assessed using the EORTC QLQ-C30, and the ovarian (QLQ-OV28) and colorectal cancer (QLQ-CR38) modules. HRQoL questionnaires were administered at baseline, after surgery, after end of treatment, and every three months thereafter. HRQoL was a secondary endpoint, with the prespecified focus on the QLQ-C30 summary score and symptom scores on fatigue, neuropathy and gastro-intestinal symptoms. HRQoL was analysed using linear and non-linear mixed effect models.

RESULTS

In total, 245 patients were randomized. One-hundred-ninety-seven patients (80%) completed at least one questionnaire. No significant difference over time in the QLQ-C30 summary scores was observed between the study arms (p-values for linear and non-linear growth: p > 0.133). The pattern over time for fatigue, neuropathy and gastro-intestinal symptoms did not significantly differ between treatment arms.

CONCLUSION

The addition of HIPEC to interval CRS does not negatively impact HRQoL in patients with stage III ovarian cancer who are treated with interval CRS due to the extent of disease. These HRQoL results, together with the improvement in RFS and OS, support the viability of HIPEC as an important treatment option in this patient population. CLINICALTRIALS.

Health utility and health-related quality of life of Japanese prostate cancer patients according to progression status measured using EQ-5D-5L and FACT-P

PURPOSE

To obtain health utility data to allow for cost-effectiveness analysis in groups stratified by disease progression along with health-related quality of life (HRQoL) information in Japanese prostate cancer (PC) patients.

METHODS

In this cross-sectional observational study, EuroQol-5 Dimension- 5 Level (EQ-5D-5L), EuroQol Visual Analog Scale (EQ-VAS), and Functional Assessment of Cancer Therapy-Prostate (FACT-P) measures were used to examine utility, VAS scores, and disease-specific HRQoL, respectively. Scores obtained were statistically examined for the correlation among measures and domains. Parameter estimates of statistically significant factors were assessed using generalized linear models (GLM).

RESULTS

A total of 380 patients stratified by their disease progression status were analyzed. The numbers (%) of patients in groups stratified as having localized (L), localized progression (LP), distant metastatic (DM), and DM-castration-resistant PC (CRPC) were 275 (72.4), 40 (10.5), 27 (7.1), and 38 (10.0), respectively. EQ-5D-5L mean (standard deviation, SD) scores of L, LP, DM, and DM-CRPC in study participants were 0.87 (0.15), 0.86 (0.15), 0.85 (0.18), and 0.84 (0.17), respectively. The mean (SD) scores assessed by EQ-5D-5L, EQ-VAS, and FACT-P instruments were 0.86 (0.16), 74.6 (16.8), and 110.8 (19.6), respectively. Utility scores correlated well with FACT-P scores. Eastern Cooperative Oncology Group performance status had significant influences on all instruments' scores.

CONCLUSIONS

We obtained health utility and HRQoL scores of Japanese PC patients stratified by disease progression in detail. Our results will be useful for establishing cost-effectiveness analyses in Japanese PC settings.

Comparison of EQ-5D-5L and SPVU-5D for measuring quality of life in patients with venous leg ulcers in an Australian setting

PURPOSE

Given the importance of measuring health-related quality of life (HRQoL) for cost-utility studies, this study aimed to determine the validity and responsiveness of two preference-based HRQoL instruments, the EuroQol-five dimensions-five levels questionnaire (EQ-5D-5L) and the Sheffield Preference-based Venous Ulcer questionnaire (SPVU-5D) in patients with venous leg ulcers (VLUs) in an Australian setting.

METHODS

This study analysed de-identified data collected from 80 patients with VLUs recruited by a prospective study in Brisbane, Queensland, Australia. Patients were asked to complete EQ-5D-5L and SPVU-5D surveys at baseline, 1-month, 3-month and 6-month follow-up as part of the prospective study. Baseline data and follow-up data were pooled to test the construct validity and level of agreement of the two instruments. Follow-up data were used to test the responsiveness.

RESULTS

The ceiling effects were negligible for EQ-5D-5L and SPVU-5D utility scores. Both instruments were able to discriminate between healed VLU and unhealed VLU and showed great responsiveness when healing status changed over time. Weak to strong correlations were found between dimensions of EQ-5D-5L and SPVU-5D. The utility scores produced from EQ-5D-5L were generally lower.

CONCLUSIONS

This study found that both EQ-5D-5L and SPVU-5D were valid and responsive in detecting change of VLU healing status among a small Australian population. Both instruments may be used in economic evaluation studies that involve patients with healed or unhealed VLUs. However, given the limitations presented in this study, further research is necessary to make sound recommendations on the preferred instrument in economic evaluation of VLU-related interventions.

EQ-5D-Y-5L: developing a revised EQ-5D-Y with increased response categories

Purpose

EQ-5D-Y is a generic measure of health status for children and adolescents aged 8–15 years. Originally, it has three levels of severity in each dimension (3L). This study aimed to develop a descriptive system of EQ-5D-Y with an increased number of severity levels and to test comprehensibility and feasibility.

Methods

The study was conducted in Germany, Spain, Sweden and the UK. In Phase 1, a review of existing instruments and focus group interviews were carried out to create a pool of possible labels for a modified severity classification. Participants aged 8–15 rated the severity of the identified labels in individual sorting and response scaling interviews. In Phase 2, preliminary 4L and 5L versions were constructed for further testing in cognitive interviews with healthy participants aged 8–15 years and children receiving treatment for a health condition.

Results

In Phase 1, a total of 233 labels was generated, ranging from 37 (UK) to 79 labels (Germany). Out of these, 7 to 16 possible labels for each dimension in the different languages were rated in 255 sorting and response scaling interviews. Labels covered an appropriate range of severity on the health continuum in all countries. In Phase 2, the 5L version was generally preferred (by 68–88% of the participants per country) over the 4L version.

Conclusions

This multinational study has provided a version of the EQ-5D-Y with 5 severity levels in each dimension. This extended version (EQ-5D-Y-5L) requires testing its psychometric properties and its performance compared to that of the original EQ-5D-Y-3L.

Assessing disease experience across the life span for individuals with osteogenesis imperfecta: challenges and opportunities for patient-reported outcomes (PROs) measurement: a pilot study

Background

Patient reported outcome (PRO) information is crucial for establishing better patient-provider communication, improving shared decision-making between clinicians and patients, assessing patient responses to therapeutic interventions, and increasing satisfaction with care. We used the Brittle Bones Disease Consortium (BBDC) Contact Registry for People with OI, managed by the Rare Disease Clinical Research Network (RDCRN) to (1) to evaluate the construct validity of the Patient-Reported Outcome Measurement Information System® (PROMIS®) to record important components of the disease experience among individuals with OI; and (2) explore the feasibility of using a registry to recruit individuals with OI to report on health status. Our long-term goal is to enhance communication of health and disease management findings back to the OI community, especially those who do not have access to major OI clinical centers.

Results

We demonstrated the construct validity of PROMIS instruments in OI. Our results confirm that the scores from most domains differ significantly from the general US population: individuals with OI have worse symptom burden and functioning. We found no excessive floor or ceiling effects. Our study demonstrates that the BBDC Contact Registry can be used to recruit participants for online health status surveys. However, there are numerous challenges that must be addressed: lack of self-knowledge of OI type, under-representation of men, limited ethnic diversity, and imperfect questionnaire completion rates.

Conclusion

Our pilot study demonstrated the feasibility of using a contact registry to recruit respondents from the OI community and to obtain analyzable PROMIS data regarding disease experience. Because the results differ from the general population and avoid excessive floor and ceiling effects, PROMIS instruments can be used to assess response to therapeutic interventions in individuals with OI. Future directions will include (1) development and validation of an OI-specific patient-based classification system that aggregates persons with similar clinical characteristics and risks for complications to identify treatment needs; and (2) integrating these PRO tools into routine patient care and research studies.

Cross-cultural validation of the Bengali version KIDSCREEN-27 quality of life questionnaire

Background

Measuring the health-related quality of life (HRQoL) of adolescents, including those with cerebral palsy (CP) (the major cause of childhood physical disability worldwide) in Bangladesh is pertinent although there is a dearth of validated instruments for assessing this concept. For application in a case-control study comparing HRQoL between adolescents with CP and peers without disability in Bangladesh (a typical low- and middle-income country) we cross-culturally translated and psychometrically tested KIDSCREEN-27.

Methods

KIDSCREEN-27 was translated to Bengali using forward and backwards translation protocol and interviewer administered to adolescents with CP and their age and sex matched peers without disability. Primary caregivers were included for proxy-report. Sociodeomgraphic characterists and clinical information were extracted from the Bangladesh Cerebral Palsy Register (BCPR) and adolescent mental health was assessed using the Bengali version Strenghts and Difficulties Questionnaire (SDQ). Feasibility, floor and ceiling effect, internal consistency, content and construct validity of KIDSCREEN-27 were tested.

Results

Feasibility, floor and ceiling effect and internal consistency of KIDSCREEN-27 was good for both self- and proxy-report questionnaires; nil missing scores except ‘school environment’ (11.0% to 74.7%) which correlated to rates of non-school attendance; floor and ceiling effect ≤10.4% except ‘peers and social support’ 23.4%; Cronbach’s alpha 0.67 to 0.91. Instrument validity was strong; factor analysis reflected original instrument dimensions within one to three factors and difference in known groups was observed by CP and adolescent mental health (p < 0.05).

Conclusion

KIDSCREEN-27 successfully translated to Bengali and both the self and proxy-report questionnaires showed good psychometric properties indicating suitability for case-control assessment of HRQoL between adolescents with CP and peers without disability in Bangladesh.

Patient-Reported Outcomes in Oncology, Beyond Randomized Controlled Trials

The goal of the treatment of a disease has moved from treating organs and diseases through symptoms, biological parameters and imaging towards treating a human being as a whole. The treatments should deliver benefits that patients can personally perceive. However, the patient's perspective does not always match the one of those surrounding them. Illustratively, patients' symptom assessments are more predictable for daily health status, whereas clinicians' symptom measurements are more related to clinical outcomes. The term, patient-reported outcomes (PROs), includes any data that are reported directly by the patient without an intermediary, such as a family member or a healthcare professional. The use of PROs in oncology trials is increasing and the U.S. Food and Drug Administration has published guidelines on the review and evaluation of PROs. However, while PROs are increasingly used in clinical trials, they are rarely used in daily clinical practice. Further, healthcare payers are concerned with issues related to relevance, quality, and interpretability of these outcomes.

Systematic review of health state utility values in metastatic non-small cell lung cancer with a focus on previously treated patients

BACKGROUND

Health state utility values (HSUVs) are an important input to economic evaluations and the choice of HSUV can affect the estimate of relative cost-effectiveness between interventions. This systematic review identified utility scores for patients with metastatic non-small cell lung cancer (mNSCLC), as well as disutilities or utility decrements relevant to the experience of patients with mNSCLC, by treatment line and health state.

METHODS

The MEDLINE®, Embase and Cochrane Library databases were systematically searched (September 2016) for publications describing HSUVs in mNSCLC in any treatment line. The EQ-5D website, the School of Health and Related Research Health Utilities Database (ScHARRHUD) and major pharmacoeconomic and clinical conferences in 2015-2016 were also queried. Studies in adults with previously treated mNSCLC were selected for further analysis. The information extracted included study design, description of treatment and health state, respondent details, instrument and tariff, HSUV or (dis) utility decrement estimates, quality of study, and appropriateness for use in economic evaluations.

RESULTS

Of 1883 references identified, 36 publications of 34 studies were included: 19 reported EQ-5D scores; eight reported HSUVs from valuations of vignettes made by members of the public using standard gamble (SG) or time trade-off (TTO); two reported SG or TTO directly elicited from patients; two reported EQ-5D visual analogue scale scores only; one reported Assessment of Quality of Life instrument scores; one reported HSUVs for caregivers to patients with mNSCLC using the 12-item Short-Form Health Survey; and one estimated HSUVs based on expert opinion. The range of HSUVs identified for comparable health states showed how differences in study type, tariff, health state and the measures used can drive variation in HSUV estimates.

CONCLUSIONS

This systematic review provides a set of published HSUVs that are relevant to the experience of adult patients previously treated for mNSCLC. Our review begins to address the challenge of identifying reliable estimates of utility values in mNSCLC that are suitable for use in economic evaluations, and also highlights how varying estimates result from differences in methodology.

Health-related quality of life in cleft lip and/or palate patients - A cross-sectional study from preschool age until adolescence

PURPOSE

Cleft lip and/or palate (CLP) is the most common congenital craniofacial anomaly. Multiple operations, long-lasting supplementary treatments, as well as impaired functional and esthetic outcome might have a negative impact on patients' social-emotional functioning and self-esteem, resulting in a lower health-related quality of life (HRQoL).

PATIENTS AND METHODS

This cross-sectional study aimed to evaluated CLP patients' HRQoL from preschool age (4 years) until adolescence (18 years) using the age-specific German KINDL^R questionnaire. We compared self-reports and parent proxy-reports, as well as reference values from an age-matched German norm population. Multivariate analysis was applied to identify mediating factors, e.g. cleft type, age, and gender. Additionally, a KINDSCREEN-10 questionnaire was used to implement a screening tool in the clinical routine.

RESULTS

In total, 134 participants (average age 9.0 ± 3.8 years; 47.8% female) were included. Compared with German normative data, the evaluation revealed a significantly higher 'total QoL' in all self-report groups (Kiddy-, Kid-, Kiddo-KINDL^R) and a significantly higher proxy rating for children aged 7-13 years. Multivariate analysis verified a significant disparity between self-reports and parents' conceptions of HRQoL, as well as a deterioration of the ratings with increasing age. No significant effects of other contributing factors, e.g. cleft type and gender, were found. The KIDSCREEN-10 questionnaire successfully confirmed these findings.

CONCLUSIONS

Surprisingly, our survey revealed a higher HRQoL in cleft patients compared with normative data from healthy controls. But because the return rate of the forwarded questionnaire was low, this may have contributed to bias. Keeping this in mind, we may conclude at least that the HRQoL in our cleft patients was not significantly lower than in healthy children. On the other hand, it can be assumed that the special attention of the parents and the support from speech therapy and other medical professionals may have contributed to a positive effect on family interaction, communication skills, and self-esteem.

Prospective evaluation of the Quality of Life after Brain Injury (QOLIBRI) score: minor differences in patients with major versus no or mild traumatic brain injury at one-year follow up

Background

The Quality of Life after Brain Injury (QOLIBRI) score was developed to assess disease-specific health-related quality of life (HRQoL) after traumatic brain injury (TBI). So far, validation studies on the QOLIBRI were only conducted in cohorts with traumatic brain injury. This study investigated the longer-term residuals in severely injured patients, focusing specifically on the possible impact of major TBI.

Methods

In a prospective questionnaire investigation, 199 survivors with an injury severity score (ISS) > 15 participated in one-year follow-up. Patients who had sustained major TBI (abbreviated injury scale, AIS head > 2) were compared with patients who had no or only mild TBI (AIS head ≤ 2). Univariate analysis (ANOVA, Cohen’s kappa, Pearson’s r) and stepwise linear regression analysis (B with 95% CI, R, R²) were used.

Results

The total QOLIBRI revealed no differences in one-year outcomes between patients with versus without major TBI (75 and 76, resp.; p = 0.68). With regard to the cognitive subscore, the group with major TBI demonstrated significantly more limitations than the one with no or mild TBI (p < 0.05). The AIS head correlated significantly with the cognitive dimension of the QOLIBRI (r = − 0.16; p < 0.05), but not with the mental components of the SF-36 or the TOP. In multivariate analysis, the influence of the severity of head injury (AIS head) on total QOLIBRI was weaker than that of injured extremities (R² = 0.02; p < 0.05 vs. R² = 0.04; p = 0.001) and equal to the QOLIBRI cognitive subscore (R² = 0.03, p < 0.01 each).

Conclusions

Given the unexpected result of similar mean QOLIBRI total score values and only minor differences in cognitive deficits following major trauma independently of whether patients sustained major brain injury or not, further studies should investigate whether the QOLIBRI actually has the discriminative capacity to detect specific residuals of major TBI. In effect, the score appears to indicate mental deficits following different types of severe trauma, which should be evaluated in more detail.

Health-related quality of life in Canadians with asthma: A case-control study using census data

BACKGROUND

Asthma is a common medical condition that impacts the lives of many Canadians; yet the health-related quality of life (HRQoL) in persons with asthma relative to the general population (GP) is poorly studied. In this study, data from the Canadian Community Health Survey (CCHS) 2013 was used to quantify and compare the HRQoL of the asthmatic population (AP) and the GP.

METHODS

A representative survey sample of Canadians was taken from the CCHS to compare the Health Utilities Index Mark 3 (HUI3) scores, a generic HRQoL measure, between the AP (n = 572) and the GP (n = 6518). The HUI3 multi-attribute utility (MAU) and the single-attribute utility (SAU) scores between the two sample groups were studied. The CCHS 2013 dataset was explored as the primary analysis, while the 2012 dataset was used as the confirmatory analysis to verify the consistency of the results.

RESULTS

Clinically important difference was found in the MAU score between the AP and GP (p < 0.001, Effect size = 0.30). MANOVA on the eight SAU scores with post-hoc test revealed that the AP had a lower mean score of vision (p < 0.001, Effect size = 0.36) and pain/disconfort (p < 0.001, Effect size = 0.29). Those findings were consistent with the CCHS 2012 dataset result.

CONCLUSIONS

These results provided evidence that in Canada, having asthma significantly worsens asthma patients' overall HRQoL and imposes significant impacts on the patients' vision and pain/discomfort. Therefore, there is room for improvement in the currently available asthma therapies so patients could achieve better HRQoL; particular focus should be given to the pain/discomfort and vision health domains.

Changes in upper extremity function, ADL, and HRQoL in colorectal cancer patients after the first chemotherapy cycle with oxaliplatin: a prospective single-center observational study

PURPOSE

Oxaliplatin, an important chemotherapeutic agent in colorectal cancer, causes chemotherapy-induced peripheral neuropathy (CIPN), for which prophylactic or therapeutic interventions are lacking. We aimed to investigate changes in upper extremities, activities of daily living (ADL), and health-related quality of life (HRQoL) parameters after the first chemotherapy cycle.

METHODS

Thirty-eight colorectal cancer patients scheduled to receive the leucovorin, 5'-fluorouracil, oxaliplatin (FOLFOX) therapy or the capecitabine, oxaliplatin (CAPOX) therapy, participated. Patients underwent objective assessment of sensory function, muscular strength, and manual dexterity and answered the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and the Disabilities of the Arm, Shoulder, and Hand-Disability/Symptom (DASH-DS) questionnaires for subjective assessment. The CIPN was assessed at baseline and prior to the second drug cycle.

RESULTS

Light touch sensation in both hands worsened significantly after the first drug cycle, though no significant changes were observed in muscular strength and manual dexterity. The QLQ-C30 analysis showed that Physical Functioning, Role Functioning, Nausea and Vomiting, and Dyspnea were significantly worse, whereas Emotional Functioning was improved. The DASH-DS analysis revealed significant worsening of dysfunction and subjective symptoms.

CONCLUSIONS

Our results suggest that light touch sensation may worsen even in the absence of multiple chemotherapy cycles. Even if arm and hand function (muscular strength and manual dexterity) is apparently intact, patients may experience dysfunction and decreased HRQoL. For preserving or improving patients' ADL and HRQoL, it is imperative to provide support at chemotherapy initiation.

Multimorbidity and health-related quality of life among the community-dwelling elderly: A longitudinal study

OBJECTIVES

Multimorbidity is a growing public health problem. The objective of this study was to investigate the impact of multimorbidity on health-related quality of life (HRQoL) of the elderly.

METHODS

A 24-month longitudinal study was conducted on the community-dwelling elderly. There were 411 elderly persons with complete follow-up. Information on thirteen chronic conditions was collected at baseline. Via a multi-dimensional scale, HRQoL was measured at baseline, 18 and 24 months post-baseline, respectively. Exploratory factor analyses were performed to identify multimorbidity patterns. The linear mixed effects models were conducted to analyze the associations between all dimensions of HRQoL and multimorbidity including distinct multimorbidity patterns.

RESULTS

Multimorbidity was found to be negatively associated with HRQoL except memory function. We identified three multimorbidity patterns, which were mainly labelled as degenerative disorders, digestive/respiratory disorders, cardiovascular/metabolic disorders, respectively. And three multimorbidity patterns were associated with lower HRQoL including general health, body function, self-care ability and social adaptability. Besides, the elderly with the multimorbidity pattern mainly labelled as digestive/respiratory disorders or cardiovascular/metabolic disorders had a decline on emotion than those without multimorbidity. According to the analysis of the longitudinal data of the sample, general health, self-care ability, emotion and social adaptability of the participants decreased in different degrees every month.

CONCLUSIONS

Multimorbidity was associated with lower HRQoL of the community-dwelling elderly. Distinct multimorbidity patterns had various impacts on different dimensions of HRQoL. Further studies should be carried out to investigate effective measures to improve HRQoL of the elderly with multimorbidity.

A systematic literature review of health state utility values in head and neck cancer

BACKGROUND

Health state utility values (HSUVs) are essential parameters in model-based economic evaluations. This study systematically identifies HSUVs in head and neck cancer and provides guidance for selecting them from a growing body of health-related quality of life studies.

METHODS

We systematically reviewed the published literature by searching PubMed, EMBASE and The Cochrane Library using a pre-defined combination of keywords. The Tufts Cost-Effectiveness Analysis Registry and the School of Health and Related Research Health Utilities Database (ScHARRHUD) specifically containing health utilities were also queried, in addition to the Health Economics Research Centre database of mapping studies. Studies were considered for inclusion if reporting original HSUVs assessed using established techniques. The characteristics of each study including country, design, sample size, cancer subsite addressed and demographics of responders were summarized narratively using a data extraction form. Quality scoring and critical appraisal of the included studies were performed based on published recommendations.

RESULTS

Of a total 1048 records identified by the search, 28 studies qualified for data extraction and 346 unique HSUVs were retrieved from them. HSUVs were estimated using direct methods (e.g. standard gamble; n = 10 studies), multi-attribute utility instruments (MAUIs; n = 13) and mapping techniques (n = 3); two studies adopted both direct and indirect approaches. Within the MAUIs, the EuroQol 5-dimension questionnaire (EQ-5D) was the most frequently used (n = 11), followed by the Health Utility Index Mark 3 (HUI3; n = 2), the 15D (n = 2) and the Short Form-Six Dimension (SF-6D; n = 1). Different methods and types of responders (i.e. patients, healthy subjects, clinical experts) influenced the magnitude of HSUVs for comparable health states. Only one mapping study developed an original algorithm using head and neck cancer data. The identified studies were considered of intermediate quality.

DISCUSSION

This review provides a dataset of HSUVs systematically retrieved from published studies in head and neck cancer. There is currently a lack of research for some disease phases including recurrent and metastatic cancer, and treatment-related complications. In selecting HSUVs for cost-effectiveness modeling purposes, preference should be given to EQ-5D utility values; however, mapping to EQ-5D is a potentially valuable technique that should be further developed in this cancer population.

Characterization of circadian COPD symptoms by phenotype: Methodology of the STORICO observational study

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. The symptoms of COPD are troublesome, variable, can occur during all parts of the 24-h day and have a substantial impact on patients' health status, quality of life and healthcare resource utilization. Reducing symptoms, improving health status and increasing physical activity are major goals in the management of stable COPD. In order to provide effective, patient-oriented care, patients should be evaluated on the basis of lung function, frequency of symptoms and patient-perceived impact of symptoms on their lives and treatment decisions made on a case-by-case basis. The identification of COPD phenotypes is an evolving debate and literature data about the circadian variation of COPD symptoms according to phenotypes are nowadays lacking. The ongoing STORICO (STudio Osservazionale sulla caratteRizzazione dei sIntomi delle 24 ore nei pazienti con BPCO) study (NCT03105999) is aimed to describe by clinically defined phenotypes the frequency and 12-month evolution of early-morning, day- and night-time COPD symptoms in a cohort of 600 Italian patients with stable COPD. Secondary objectives include the description of the 12-month variation of outcomes of interest according to phenotypes and of the healthcare resources utilization (overall and by phenotype) during 12-month observation. An exploratory analysis will be conducted aimed to phenotype COPD patients in an alternative researcher-independent way based on circadian pattern of symptoms combined with measures of respiratory function, health-related quality of life and comorbidity. The present paper describes the methodology of the STORICO study.

Effects of a brief, pedometer-based behavioral intervention for individuals with COPD during inpatient pulmonary rehabilitation on 6-week and 6-month objectively measured physical activity: study protocol for a randomized controlled trial

Background

Pulmonary rehabilitation programs often fail to substantially enhance long-term physical activity in patients with chronic obstructive pulmonary disease (COPD). The reasons for successful physical activity changes in patients with COPD are not well understood. The need to better understand the determinants of physical activity in patients with COPD and effective rehabilitation strategies to improve physical activity is evident.

Methods/design

The STAR study (Stay Active after Rehabilitation) investigates, in a randomized controlled trial, the additional effect of a pedometer-based behavior-change intervention during inpatient pulmonary rehabilitation on objectively measured physical activity 6 weeks and 6 months post rehabilitation. The intervention uses the behavior-change techniques (1) instruction on how, where and when to perform the behavior, (2) prompt goal setting for physical activity, (3) prompt self-monitoring of behavior, and (4) feedback on behavior. The primary outcome of physical activity will be measured using a physical activity monitor (Actigraph wGT3X-BT) for a period of 7 days, firstly 2 weeks before rehabilitation begins (t0) as well as 6 weeks and 6 months after rehabilitation (t3, t4). Additionally, to predict physical activity progression after rehabilitation, a complex personal diagnostics battery, including questionnaires as well as functional assessments, is to be carried out at the start and end of rehabilitation (t1, t2). This battery is based on the foundational ideas of the Physical Activity-Related health Competence model.

Five hundred and two patients with COPD, aged 18 years or older and admitted for an approved pulmonary rehabilitation, will be enrolled in the STAR study.

Discussion

The STAR study is designed as a randomized controlled trial to gain a better understanding of the personal determinants of physical activity in patients with COPD and to evaluate a pedometer-based physical activity-change intervention in the context of inpatient pulmonary rehabilitation. The results enable the future identification of patients with COPD who will find it difficult to engage in long-term physical activity after rehabilitation. Based on this, intervention strategies to promote physical activity in the content of pulmonary rehabilitation can be optimized.

Health-related quality of life, cognitive screening, and functional status in a randomized phase III trial (EF-14) of tumor treating fields with temozolomide compared to temozolomide alone in newly diagnosed glioblastoma

We characterized health-related quality of life (HRQoL), cognitive, and functional status in newly diagnosed glioblastoma (GBM) patients receiving Tumor treating fields (TTFields) with temozolomide (TMZ) versus TMZ alone in a planned interim analysis of a randomized phase III trial [NCT00916409], which showed significant improvement in progression-free and overall survival with TTFields/TMZ. After radiotherapy with concomitant TMZ, newly diagnosed GBM patients were randomized (2:1) to TTFields/TMZ (n = 210) or TMZ (n = 105). Interim analysis was performed in 315 patients with ≥18 months of follow-up. HRQoL, a secondary endpoint, was evaluated in per-protocol patient population and expressed as change from baseline (CFB) at 3, 6, and 9 months for each subscale in the EORTC QLQ-C30/BN20. Karnofsky performance scores (KPS) and Mini-Mental State Examination scores (MMSE) were assessed. CFB in HRQoL was balanced in treatment groups at the 12-month time point. Initially, HRQoL improved in patients treated with TTFields/TMZ (CFB3: 24% and CFB6: 13%) versus TMZ (CFB3: −7% and CFB6: −17%), though this difference was no longer evident at the 9-month point. General scales, including physical and social functioning, showed no difference at 9 and 12 months. TTFields/TMZ group reported higher concerns of “itchy skin”. KPS over 12 months was just below 90 in both groups. Cognitive status (MMSE) was stable over time. HRQoL, KPS, and MMSE were balanced in both groups over time. There was no preliminary evidence that HRQoL, cognitive, and functional status is adversely affected by the continuous use of TTFields.

Systematic review of the health-related quality of life issues facing adolescents and young adults with cancer

PURPOSE

For adolescents and young adults (AYAs), the impact of a cancer diagnosis and subsequent treatment is likely to be distinct from other age groups given the unique and complex psychosocial challenges of this developmental phase. In this review of the literature, we report the health-related quality of life (HRQoL) issues experienced by AYAs diagnosed with cancer and undergoing treatment.

METHODS

MEDLINE, EMBASE, CINAHL, PsychINFO and the Cochrane Library Databases were searched for publications reporting HRQoL of AYAs. Issues generated from interviews with AYAs or from responses to patient reported outcome measures (PROMs) were extracted.

RESULTS

166 papers were reviewed in full and comprised 72 papers covering 69 primary studies, 49 measurement development or evaluation papers and 45 reviews. Of the 69 studies reviewed, 11 (16%) used interviews to elicit AYAs' descriptions of HRQoL issues. The majority of the PROMs used in the studies represent adaptations of paediatric or adult measures. HRQoL issues were organised into the following categories: physical, cognitive, restricted activities, relationships with others, fertility, emotions, body image and spirituality/outlook on life.

CONCLUSION

The HRQoL issues presented within this review are likely to be informative to health care professionals and AYAs. The extensive list of issues suggests that the impact of a cancer diagnosis and treatment during adolescence and young adulthood is widespread and reflects the complexities of this developmental phase.

The Swedish translation and cross-cultural adaptation of the Functional Assessment of Chronic Illness Therapy - Cervical Dysplasia (FACIT-CD): linguistic validity and reliability of the Swedish version

Background

Cervical dysplasia is a precancerous condition, which has been shown to create anxiety in women. To be able to investigate these women’s health-related quality of life, a disease-specific instrument is required. There does not seem to be a Swedish version of an instrument to screen for this specific disease. Therefore, this study aims to translate and cross-culturally adapt the Functional Assessment of Chronic Illness Therapy – Cervical Dysplasia (FACIT-CD) into a Swedish context and evaluate its linguistic validity and reliability.

Methods

The Functional Assessment of Chronic Illness Therapy (FACIT) translation methodology was used, which consists of several steps including pilot testing of the FACIT-CD instrument through cognitive debriefing interviews. Ten women diagnosed with cervical dysplasia participated in the cognitive debriefing interviews. The internal consistency reliability of the Swedish FACIT-CD was estimated by Cronbach’s alpha coefficient. Homogeneity of the items was evaluated by corrected item-total correlations. The sample consists of 34 women who were diagnosed with cervical dysplasia.

Results

The translation and cross-cultural adaptation went smoothly without any problems for the majority of the items. The cognitive debriefing interviews indicated that the Swedish FACIT-CD consists of relevant items, is easy to understand and complete, and has unambiguous and comprehensive response categories. The translation and cross-cultural adaptation resulted in a Swedish FACIT-CD, which is conceptually and semantically equivalent to the English version and linguistically valid. The total scale of the Swedish FACIT-CD exhibited good internal consistency reliability with a Cronbach’s alpha coefficient of 0.84, and all of the subscales exhibited acceptable value between 0.71 and 0.81 except the Relationships subscale, which had a value of 0.67. Finally, all but four items exceeded the acceptable level for the corrected item-total correlations of ≥ 0.20.

Conclusions

The Swedish FACIT-CD is conceptually and semantically equivalent to the English version and linguistically valid; further, it exhibits good internal consistency reliability.

ASPECTS OF PATIENT REPORTED OUTCOMES IN RARE DISEASES: A DISCUSSION PAPER

OBJECTIVES

A patient reported outcome (PRO) is "any report of the status of a patient's health condition that comes directly from the patient without interpretation of the patient's response by a clinician or anyone else" (USFDA 2009). PROs are discussed widely, and many regard the patients' perspective on treatment benefit as very valuable. Although many PROs have shown satisfactory measurement properties including reliability, validity, and responsiveness, there is great concern about risk of bias, that is, in clinical trials.

METHODS

Differences in perspectives of PRO measurement in rare diseases are given arising from methodology, clinical, HTA, and patient advocacy views.

RESULTS

PROs are playing an important role in dealing with treatment benefit especially in small sample size as occurring often in rare diseases. Challenges remain especially regarding lack of responsiveness of generic measures, limited capture of all patient relevant aspects, study design and high risk of bias.

CONCLUSIONS

PROs seem a valuable instrument to detect patient relevant aspects in rare diseases. They should be seen in addition to other approved assessment methods as randomized controlled trials but not as their substitute.

The role of coping strategies on health-related quality of life in adults with anorectal malformations

PURPOSE

Coping strategies have been acknowledged as crucial for the well-being and for health-related quality of life (HRQoL). The main aim of the present study is to determine whether different types of coping strategies predict HRQoL in patients born with ARM, above and beyond the variance explained by fecal and urinary continence.

METHODS

71 adult patients from the Italian Parents' and Patients' Organization for Anorectal Malformations (AIMAR) participated in the study. Participants completed measures of fecal and urinary continence of the Hirschsprung Disease/Anorectal Malformation Quality of Life (HAQL) (Hanneman et al. in Dis Col Rect 44:1650-1660, 2001), the Short Form Health Survey (SF-36) (Apolone and Mosconi in J Clin Epidemiol 51:1025-1036, 1998), and the Brief Coping Orientation to Problems Experienced (COPE) Inventory (Carver in Int J Behav Med 4:92-100, 1997), which measures different coping strategies: maladaptive, problem-focused and emotion-focused.

RESULTS

Hierarchical regression analyses showed that fecal continence (β = 0.53, p < 0.01) and urinary continence significantly predict (β = 0.23, p < 0.05) Physical HRQoL. Fecal continence (β = 0.36, p < 0.01) and maladaptive coping strategies significantly predict (β = -0.27, p < 0.05) Mental HRQoL.

CONCLUSION

Besides considering the importance of fecal and urinary continence for Physical HRQoL, these findings indicate that maladaptive coping strategies are associated with worse Mental HRQoL. Interventions aimed at enhancing the patients' HRQoL should target coping strategies by reducing denial, behavioral disengagement, substance abuse, and self-blame.

Prevalence of cancer chemotherapy-related problems, their relation to health-related quality of life and associated supportive care: a cross-sectional survey

PURPOSE

The purpose of this study was to identify the treatment-associated problems that most impact on patients undergoing cancer chemotherapy, how problems relate to experiences of supportive care and variations in experience between cancer treatment centres.

METHODS

A survey administered to patients at six cancer centres in England explored variations of prevalence of 17 cancer chemotherapy-associated problems and associated supportive care. Problem items were identified as the most frequently experienced and severe when experienced in a scoping and consensus exercise. A health-related quality of life (HRQoL) measure, the EQ5D, was included to measure impact of problems.

RESULTS

A total of 363 completed questionnaires were returned (response rate 43 %, median 61 %). The most prevalent problem was 'tiredness/fatigued' (90 %), followed by 'changes in taste & smell' (69 %) and 'difficulty managing everyday tasks' (61 %). Significant variations in problem prevalence existed between centres, and some common problems were rarely reported in the literature. Regression analysis found that almost all problems were significantly associated with HRQoL, with social/emotional problems having as much impact on HRQoL as physical/psychological side effects of treatment. Greatest effect size was for difficulty managing everyday tasks. Respondents reported significant variations in supportive care between centres, with more supportive care received for physical/psychological problems than for social/emotional problems. Findings indicated that patients who received increased supportive care experienced less severe problems.

CONCLUSION

The most common and distressing chemotherapy-associated problems were identified. These problems are mitigated by quality supportive care. Routine measurement and monitoring of problem items and supportive care are warranted to facilitate benchmarking and service improvements both within and between cancer centres.

Examining the relationship between antihypertensive medication satisfaction and adherence in older patients

BACKGROUND

The relationship between medication adherence and treatment satisfaction has been consistently positive, however, this relationship has not been examined among older adults with hypertension.

OBJECTIVES

The aim of this study was to examine the relationship between medication adherence and treatment satisfaction among a sample of older adults with hypertension.

METHODS

This was a survey-based cross-sectional study in which seven community senior centers in the city of Memphis, Tennessee and its surrounding areas were visited. Individuals aged 60 years and older with self-reported hypertension who visited the community senior centers between August and December 2013 were asked to participate. The participants' satisfaction with their antihypertensive medications was assessed using a newly developed scale. The Short Form Health Survey (SF-12v2) was used to assess the health-related quality of life (HRQoL). The Primary Care Assessment Survey (PCAS) Communication scale was used to assess the satisfaction with health care provider communication. The Beliefs About Medicines Questionnaire (BMQ-General) was used to assess the participant beliefs about medications. The eight-item Morisky Medication Adherence Scale (MMAS-8) was used to assess adherence to antihypertensive medications. And the Single Item Literacy Screener (SILS) was used to assess health literacy. Multiple linear regression was conducted to examine the relationship between medication adherence and satisfaction with antihypertensive therapy controlling for multiple variables.

RESULTS

One hundred and ninety participants with hypertension were included in the study. Most participants were white, women, aged ≥70 years, taking ≥2 prescription medications and having ≥2 medical conditions. After adjusting for age, education, number of prescription medications, race, health literacy, sex, marital status, SF-12v2 Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12), and PCAS-Communication scores, the overall satisfaction score of the antihypertensive medication regimen was positively and significantly associated with MMAS-8 sore (β = 0.262; 95% confidence interval, 0.007-0.517; P = 0.043).

CONCLUSIONS

Treatment satisfaction was associated with higher medication adherence among older adults with hypertension.

Predictors of Health-Related Quality of Life After Bariatric Surgery

BACKGROUND

Bariatric surgery is typically associated with improvement in health-related quality of life (HRQoL). However, recent reports are conflicting, and the aim of this study was to determine factors that would be predictive for long-term outcomes after bariatric procedures.

METHODS

One thousand five hundred and seventy-three patients at one Midwestern academic medical center who underwent any type of bariatric surgery were sent the SF-36 survey. Three hundred and fifty completed surveys collected over a 3-month period were returned. Multivariate analysis was conducted.

RESULTS

The physical and mental component scores were significantly lower than the norm population mean. Age at time of surgery, pre-surgical body mass index (BMI) and duration since surgery were negatively related to HRQoL.

CONCLUSIONS

Improvements in HRQoL following bariatric surgery do not appear to be sustained over the long term. Older patients and those with high pre-surgical obesity do not appear to have the same benefits in HRQoL over time.
