The Visual Functioning-14 (VF-14) scale is the most widely employed index of vision-related functional impairment and serves as a patient-reported outcome measure in vision-specific quality of life. The purpose of this study is to rigorously examine and validate the VF-14 scale on a Greek population of ophthalmic patients employing Rasch measurement techniques. Two cohorts of patients were sampled in two waves. The first cohort included 150 cataract patients and the second 150 patients with other ophthalmic diseases. The patients were sampled first while pending surgical or other corrective therapy and two months after receiving therapy. The original 14-item VF-14 demonstrated poor measurement precision and disordered response category thresholds. A revised eight-item version, the VF-8G (‘G’ for ‘Greek’), was tested and confirmed for validity in the cataract research population. No differential functioning was reported for gender, age, and underlying disorder. Improvement in the revised scale correlated with improvement in the mental and physical component of the general health scale SF-36. In conclusion, our findings support the use of the revised form of the VF-14 for assessment of vision-specific functioning and quality of life improvement in populations with cataracts and other visual diseases than cataracts, a result that has not been statistically confirmed previously.

Abstract Background: Systemic AL Amyloidosis is characterized by deposition by amyloid fibrils of light chains produced by clonal plasma cells. New combination therapies have substantially prolonged the life expectancy of patients with AL Amyloidosis . Still the prognosis of the disease in the majority of the patients is dismal and Quality of Life (QoL) issues should be included in clinicians' primary objectives. Nowadays, patient-reported outcome measures (PROMs) are considered one of the most responsive tools that can guide personalized interventions to optimize QoL in parallel with therapeutic interventions. The aim of this metanalysis was to establish which PROMs have been utilized in studies on AL Amyloidosis and evaluate their validity. Methods: Two independent investigators (S.B.; C.K.) systemically reviewed PubMed, Medline and EMBASE databases for publications up to May 2021 on PROMs employed to report QoL outcomes in AL Amyloidosis. The identified PROMs were subsequently assessed for their validity in this context against COSMIN (Consensus-based Standards for the selection of health Measurement Instruments) quality criteria. Results: Of the 246 publications originally retrieved, only 57 were further analysed as 92 were duplicates, 11 were irrelevant to AL Amyloidosis, 56 did nor refer to QOL and 13 reported QOL without using QOLQs, 13 were case-reports and 4 were review articles. These included 47 observational studies and 10 prospective clinical trials. In these, thirteen different PROMs were used on occasion to report QOL outcomes (SF-36; EQ-5D-3L; FACT-G; PROMIS-GH); HPRSS; DT; EORTC QLQ-C30; KCCQ-12; GAF; SWLS; STAI; CESD; MDASI) with SF-36 being the most popular (35/ 58 publications). All of them are traditionally validated in similar to AL Amyloidosis diseases (e.g. Multiple Myeloma) or in its complications (e.g. Congestive Heart Failure). In the absence of face-validity studies, the content validity of these PROMs was assessed against QOL aspects identified in literature by open questionnaires (Table 1). The outcome of the intensive analysis of these studies showed that the QoLQ fail to cover the broad spectrum of disease symptoms and current therapy-related toxicity. Furthermore, there is limited if any evidence for the validation of these tools in this context (Table 2). COSMIN criteria were met only for SF-36 and PROMIS-GH as regards internal consistency (Cronbach's a>70). Conclusions: This literature review reveals that commonly applied PROMs in studies on AL Amyloidosis do not represent the impact of this complex disease and its treatment on QoL issues. Thus, there is a need to develop a new, well-validated, disease-specific PROM that can facilitate the approval of new treatments and the adjustment of therapy-intensity according to its toxicity and QoL.

Aims The aim of this study was to evaluate health-related quality of life (HRQoL) and joint function in tenosynovial giant cell tumour (TGCT) patients before and after surgical treatment. Patients and Methods This prospective cohort study run in two Dutch referral centres assessed patient-reported outcome measures (PROMs; 36-Item Short-Form Health Survey (SF-36), visual analogue scale (VAS) for pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)) in 359 consecutive patients with localized- and diffuse-type TGCT of large joints. Patients with recurrent disease (n = 121) and a wait-and-see policy (n = 32) were excluded. Collected data were analyzed at specified time intervals preoperatively (baseline) and/or postoperatively up to five years. Results A total of 206 TGCT patients, 108 localized- and 98 diffuse-type, were analyzed. Median age at diagnosis of localized- and diffuse-type was 41 years (interquartile range (IQR) 29 to 49) and 37 years (IQR 27 to 47), respectively. SF-36 analyses showed statistically significant and clinically relevant deteriorated preoperative and immediate postoperative scores compared with general Dutch population means, depending on subscale and TGCT subtype. After three to six months of follow-up, these scores improved to general population means and continued to be fairly stable over the following years. VAS scores, for both subtypes, showed no statistically significant or clinically relevant differences pre- or postoperatively. In diffuse-type patients, the improvement in median WOMAC score was statistically significant and clinically relevant preoperatively versus six to 24 months postoperatively, and remained up to five years’ follow-up. Conclusion Patients with TGCT report a better HRQoL and joint function after surgery. Pain scores, which vary hugely between patients and in patients over time, did not improve. A disease-specific PROM would help to decipher the impact of TGCT on patients’ daily life and functioning in more detail. Cite this article: Bone Joint J 2019;101-B:272–280.

Abstract Background Patient reported outcome measurements (PROMs) are emerging as an important component of patient management in the cancer setting, providing broad perspectives on patients’ quality of life and experience. The use of PROMs is, however, generally limited to the context of randomised control trials, as healthcare services are challenged to sustain high quality of care whilst facing increasing demand and financial shortfalls. We performed a systematic review of the literature to identify any oncological benefit of using PROMs and investigate the wider impact on patient experience, in cancers of the pelvic abdominal cavity specifically. Methods A systematic review of the literature was conducted using MEDLINE (Pubmed) and Ovid Gateway (Embase and Ovid) until April 2020. Studies investigating the oncological outcomes of PROMs were deemed suitable for inclusion. Results A total of 21 studies were included from 2167 screened articles. Various domains of quality of life (QoL) were identified as potential prognosticators for oncologic outcomes in cancers of the pelvic abdominal cavity, independent of other clinicopathological features of disease: 3 studies identified global QoL as a prognostic factor, 6 studies identified physical and role functioning, and 2 studies highlighted fatigue. In addition to improved outcomes, a number of included studies also reported that the use of PROMs enhanced both patient-clinician communication and patient satisfaction with care in the clinical setting. Conclusions This review highlights the necessity of routine collection of PROMs within the pelvic abdominal cancer setting to improve patient quality of life and outcomes.

Abstract Background Patient-reported outcome measures (PROMs) are gaining increasing importance in the context of quality management. Different PROMs and scoring tools are available to assess shoulder function after proximal humeral fracture (PHFx). In Europe, these include the Constant-Murley Score (CS), Neer Score (NS), Oxford Shoulder Score (OSS), University of California at Los Angeles Score (UCLA) and Disabilities of the Arm, Shoulder and Hands Score (DASH). In addition, the health-related quality of life can be assessed by the PROMs Short Form 36 (SF-36) and EuroQol (EQ-5D). Although all these test instruments assess shoulder function, the components to be answered objectively and subjectively vary and thus the possibility of independent assessment. The aim of the present study is to compare the correlation between the results of the different PROMs and the clinical screening tools in patients with PHFx. Methods 76 patients who were treated with angular stable plate osteosynthesis for a proximal humeral fracture between 01/2001 and 12/2005 were included in this trial. The outcome was measured with PROMs or clinical scoring tools such as CS, NS, OSS, UCLA, DASH, SF-36 and EQ-5D and a correlation coefficient between those evaluation tools was calculated. In addition, a distinction was made between the two force measurement methods (wrist [HG] vs. deltoid muscle [DM]) for CS. Results The correlation of the results of CS and NS (HG: r = 0.85; p < 0.001/DM: r = 0.93; p < 0.001), CS and UCLA (HG: r = 0.83; p < 0.001/DM: r = 0.86; p < 0.001), NS and UCLA (r = 0.91; p < 0.001) as well as DASH and OSS (r = 0.88; p < 0.001) was strongly expressed. A good comparability of the results was demonstrated between CS and OSS (HG: r = 0.63; p < 0.001/DM: r = 0.66; p < 0.001) and between CS and DASH (HG: r = 0.62; p < 0.001/DM: r = 0.61; p < 0.001). The correlation of CS (HG/DM) and UCLA with the EQ-5D index was also good. Assessment of the physical components of SF-36 with CS, NS, OSS, UCLA and DASH showed a moderate to good association, while the mental components of SF-36 showed a low correlation (p > 0.05). Conclusion The assessment of shoulder function after proximal humerus fracture showed a very strong correlation within the clinical questionnaires (CS/NS/UCLA) and the PROMs (OSS/DASH). A strong correlation also exists between the clinical questionnaires and the PROMs. There was only a moderate correlation with the EQ-5D. The moderate to strong correlation between the physical components of SF-36, with almost no correlation between the mental components of SF-36, indicates that the quality of life restriction is based on a physical, but not on a mental impairment.

Abstract Introduction Comprehensive cardiac rehabilitation (CR) programs based on the bio-psycho-social approach of the international classification of functioning and disease are carried out to achieve improved prognosis, superior health-related quality of life (HRQL) and social integration. We aimed to identify predictors of returning to work (RTW) and HRQL among cardiovascular risk factors and physical performance as well as patient-reported outcome measures (PROMs) modifiable during CR. Methods We designed a prospective observational multi-center study and enrolled 1,586 patients (2017/18) in 12 German rehabilitation centers regardless of their primary allocation diagnoses (e.g. acute myocardial infarction (AMI), coronary artery bypass grafting (CABG), coronary artery disease (CAD), valvular disease). Besides general data (e.g. age, gender, diagnoses), parameters of risk factor management (e.g. smoking, lipid profile, hypertension, lifestyle change motivation), physical performance (e.g. maximum exercise capacity, endurance training load, 6-min walking distance), and PROMs (e.g. depression, heart-focused anxiety, HRQL, subjective well-being, somatic and mental health, pain, general self-efficacy, pension desire as well as self-assessment of occupational prognosis using several questionnaires) were documented at CR admission and discharge. 6 months after discharge, status of RTW and HRQL (SF-12) were captured by a follow-up (FU) survey and analyzed in multivariable regression models with multiple imputation of missing values. Results Out of the study participants, 1,262 patients (54±7 years, 77% men) responded to the follow-up survey and could be analyzed regarding the outcome parameters. Most of them were assigned to CR primarily due to AMI (40%) or CAD without myocardial infarction (18%), followed by heart valve diseases in 12% of patients and CABG (8%). 864 patients (69%) returned to work within the follow-up period. Pension desire, negative self-assessed occupational prognosis, heart-focussed anxiety, major life events, smoking and heart failure were negatively associated with RTW, while higher endurance training load, HRQL and work stress were positively associated (Figure 1). HRQL after 6 months was determined more by PROMs (e.g. pension desire, heart-focused anxiety, physical/mental HRQL in SF-12, physical/mental health in indicators of rehab-status questionnaire (IRES-24), stress, well-being in the World Health Organization well-being index and self-efficacy expectations) than by clinical parameters or physical performance. Conclusions Patient-reported outcome measures predominantly influenced RTW and HRQL in heart-disease patients, whereas patients' pension desire and heart-focussed anxiety had a dominant impact on all investigated endpoints. Therefore, the multi-component CR approach focussing on psychosocial support is crucial for subjective health prognosis and occupational resumption. Figure 1.

Background:The patient-reported outcomes are important components of quantitative methods of rheumatoid arthritis (RA) activity assessment which are used to choose the appropriate drug therapy. The value of these parameters can be significantly affected not only by the inflammatory process, but also by the psychological characteristics of the patient and, in particular, by hardiness [1].Objectives:To study the relationship between psychological factors and signs of RA activity.Methods:Patients with RA who met the EULAR/ACR 2010 criteria, and observed at the V. A. Nasonova Research Institute of Rheumatology were included. Clinical examination was performed including patient global assessment (PGA), physician global assessment (PhGA), pain measurement on a visual analog scale, tender joint count (TJC), swollen joint count (SJC). The functional status was determined by HAQ, the quality of life – by SF-36 EQ-5D, the nature of pain – by painDETECT, the presence of anxiety and depression – by HADS. Patients also completed Hardiness Survey questionnaire to assess hardiness (HDS) and 3 components of the HDS – commitment (CMT), control (CT) and challenge (CLN). Disease activity was evaluated with DAS28, CDAI, and RAPID3. All patients signed informed consent to participate in the study. Analysis of the data was performed using Spearman’s rank test, Fisher exact test, qui-square and t-tests.Results:85 patients with RA were included. There were 69 women and 16 men. Mean age was 56.7±13.1 years, disease duration – 7.6±2.7 years. 72 patients were positive for rheumatoid factor, 75 – for anti-cyclic citrullinated peptide antibody. CDAI showed high activity in 15, moderate – in 37, low – in 30, and remission in 3 patients, DAS 28 – in 10, 55, 12, and 8, and RAPID3 – in 24, 25, 15, and 21, respectively. 24 patients had subclinically or clinically expressed anxiety and 15 –subclinically or clinically expressed depression (≥8 according to HADS). In 31 patients, the painDETECT questionnaire revealed possible or probable neuropathic pain. Mean HDS was 84.8±21.7, CMT – 38.9±9.2, CT – 29.4±8.6, CLN – 17.3±7.1. These values were comparable with the corresponding population data for this age group. There was a significant inverse correlation between HDS and RA activity measures, including SJC, TJC, DAS28 (p<0.05), pain, PGA, PhGA, CDAI, RAPID3, and HAQ (p<0.01). In addition, HDS and all its components positively correlated with quality of life, assessed by SF-36 and EQ-5D (p<0.01). In patients with subclinically and clinically expressed anxiety and depression, HDS, CMT, and CT were significantly lower than in patients without anxiety and depression (p<0.01), while the values of CLN in these groups did not differ significantly.Conclusion:The results of the present study suggest that low HDS may be one of the significant factors determining RA activity level because it does not allow patients to adapt adequately to a stressful situation produced by the disease.References:[1]Maddi SR.
