Pap Z, Kalabiska I, Balogh Á, Bhattoa HP. Evaluation of the sarcopenia quality of life (SarQoL) questionnaire in community dwelling outpatient postmenopausal hungarian women. BMC Musculoskelet Disord 2023; 24:331. [PMID: 37106363 PMCID: PMC10134597 DOI: 10.1186/s12891-023-06454-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 04/24/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Sarcopenia is defined as an age-related progressive and systemic loss of muscle mass and function. World Health Organization (WHO) definition of health-related quality of life (QoL) states that health is considered "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity", and a decline in QoL is anticipated in individuals with sarcopenia. Beaudart et al. framed the concept of defining QoL in patients suffering from sarcopenia (SarQoL) based on fundamental procedures of QoL questionnaire development, expert recommendations and studies. The aim of the present study is to evaluate the discriminative power, internal consistency and floor and ceiling effects using data available from a sarcopenia study published recently, where the Hungarian version of the SarQoL questionnaire was also administered. METHODS In this cross-sectional study, data from SarQoL questionnaire administered to a postmenopausal sarcopenia study cohort (n = 100) was scrutinized for evaluation of psychometric properties of the questionnaire. Our verification of the psychometric properties consisted of discriminative power analysis, assessment of internal consistency, and floor and ceiling effects. The homogeneity of the SarQoL questionnaire, i.e., its internal consistency was measured using Cronbach's alpha coefficient. Correlation between the overall and domain SarQoL questionnaire scores and appendicular skeletal muscle mass in sarcopenic individuals was assessed. Furthermore, the difference of SarQoL overall and domain scores between sarcopenic and non-sarcopenic patients was also evaluated. RESULTS The median (interquartile range (IQR)) overall SarQoL questionnaire score was 81.5 (67.1-91.5). There was a statistically significant lower overall SarQoL score comparing sarcopenic and non-sarcopenic subjects median (IQR): 75.3 (62.1-86.3) vs. 83.7 (71.4-92.1); p = 0.041). The sarcopenic subjects showed a statistically significant (p = 0.021) correlation between the overall SarQoL score and appendicular skeletal muscle mass (Spearman's ϱ = 0.412). The overall Cronbach's alpha of 0.937 indicated a high internal consistency of the Hungarian version of the SarQoL questionnaire. No floor or ceiling effects were noted in the overall SarQoL questionnaire score. CONCLUSION In our study on community dwelling outpatient postmenopausal Hungarian women, the overall score of the Hungarian version of the SarQoL questionnaire had significant discriminative power to distinguish between sarcopenic and non-sarcopenic patients, had high internal consistency and no floor or ceiling effects.

Abstract
While health-related quality of life (HRQoL) is an important component of patient-centred care, few studies have looked at the association between HRQoL and outcomes while on OPAT. From 2014 to 2017, we conducted a prospective cohort study of all patients referred to Singapore General Hospital's (SGH) OPAT service. At baseline, we collected sociodemographic, clinical, and treatment-related factors for OPAT recipients. We also measured baseline HRQoL using the EuroQoL EQ5D-3 L. We evaluated the association between HRQoL and the following outcomes: complications experienced while on OPAT, early termination requiring readmission during planned course of OPAT, all-cause readmission 30 days after completion of OPAT, and return to work while on OPAT. We used chi-squared test for univariate analysis and cox regression for multivariate analysis. From 2014 to 2017, 1213 patients received OPAT at our centre. Of those, 13.2% (160/1213) developed complications. About 10% (132/1213) of patients were readmitted while on OPAT and OPAT was terminated early. Amongst patients who completed OPAT (N = 1081), about 3.6% (39/1081) were readmitted within 30 days after OPAT completion. About half (50.8%, 278/547) returned to work while on OPAT. On multivariate analysis, patients with perfect health-related quality of life (HRQoL) (adjusted relative risk, aRR = 0.62, 95%CI = 0.45-0.85) were less likely to experience complications, had lower risk of OPAT termination (aRR = 0.57, 95%0.38-0.86), and were more likely to return to work while on OPAT (aRR = 1.94, 95%CI = 1.30-2.89). HRQoL at baseline was significantly associated with lower risk of complications and early OPAT termination, as well as greater likelihood of return to work while on OPAT.

The Penicillin for the Emergency Department Outpatient treatment of CELLulitis (PEDOCELL) trial: update to the study protocol and detailed statistical analysis plan (SAP). Trials 2017; 18:391.

Abstract
Background Cellulitis is a painful, potentially serious, infectious process of the dermal and subdermal tissues and represents a significant disease burden. The statistical analysis plan (SAP) for the Penicillin for the Emergency Department Outpatient treatment of CELLulitis (PEDOCELL) trial is described here. The PEDOCELL trial is a multicentre, randomised, parallel-arm, double-blinded, non-inferiority clinical trial comparing the efficacy of flucloxacillin (monotherapy) with combination flucloxacillin/phenoxymethylpenicillin (dual therapy) for the outpatient treatment of cellulitis in the emergency department (ED) setting. To prevent outcome reporting bias, selective reporting and data-driven results, the a priori-defined, detailed SAP is presented here. Methods/design Patients will be randomised to either orally administered flucloxacillin 500 mg four times daily and placebo or orally administered 500 mg of flucloxacillin four times daily and phenoxymethylpenicillin 500 mg four times daily. The trial consists of a 7-day intervention period and a 2-week follow-up period. Study measurements will be taken at four specific time points: at patient enrolment, day 2–3 after enrolment and commencing treatment (early clinical response (ECR) visit), day 8–10 after enrolment (end-of-treatment (EOT) visit) and day 14–21 after enrolment (test-of-cure (TOC) visit). The primary outcome measure is investigator-determined clinical response measured at the TOC visit. The secondary outcomes are as follows: lesion size at ECR, clinical treatment failure at each follow-up visit, adherence and persistence of trial patients with orally administered antibiotic therapy at EOT, health-related quality of life (HRQoL) and pharmacoeconomic assessments. The plan for the presentation and comparison of baseline characteristics and outcomes is described in this paper. Discussion This trial aims to establish the non-inferiority of orally administered flucloxacillin monotherapy with orally administered flucloxacillin/phenoxymethylpenicillin dual therapy for the ED-directed outpatient treatment of cellulitis. In doing so, this trial will bridge a knowledge gap in this understudied and common condition and will be relevant to clinicians across several different disciplines. The SAP for the PEDOCELL trial was developed a priori in order to minimise analysis bias. Trial registration EU Clinical Trials Register (EudraCT number: 2016-001528-69). Registered on 5 April 2016.

Abstract
BACKGROUND Psychosocial factors surrounding eating and drinking, such as enjoying food, managing restrictions, and maintaining social relationships, remain under-researched in inflammatory bowel disease [IBD]. This study aimed to develop and validate a food-related quality of life [FR-QoL] questionnaire to systematically measure these issues in the IBD population. METHODS Following semi-structured interviews with 28 IBD patients, 150 potential questionnaire items were generated. These were ranked by 100 IBD patients, and items were removed based on ceiling/floor effects and high inter-item correlations [> 0.7], with 41 items being retained. In total, 323 IBD patients, 100 asthma patients [chronic disease control], and 117 healthy controls completed the FR-QoL questionnaire, alongside generic and disease-specific QoL and food satisfaction questionnaires. Principal components analysis [PCA], construct and discriminant validity, and test-retest reliability were calculated. RESULTS Twelve items were removed following PCA. The reduced questionnaire [FR-QoL-29] explained 63.9% of the variance [Cronbach's α = 0.96]. FR-QoL-29 correlated significantly with generic QoL [r = 0.697], depression [r = -0.519], anxiety [r = -0.531], and food satisfaction [r = 0.701]. The FR-QoL-29 sumscores were significantly lower for IBD (89.5, standard deviation [SD] 28.6) than asthma [125.4, SD 24.1; p < 0.001] and healthy volunteers [123.0, SD 16.5; p<0.001]. Within IBD, worse food-related QoL was found in those with moderate/high disease activity [66.7, SD 22.1] compared with remission/low disease activity [92.5, SD 28.1]. Test-retest reliability was good (intra-class correlation [ICC] = 0.83, 95% confidence interval [CI] = 0.76:0.88). CONCLUSIONS The FR-QoL-29 shows good reliability and validity across a range of IBD characteristics. This easily administered questionnaire is a useful tool in identifying poor food-related QoL and in the future may identify areas for intervention.

Abstract
BACKGROUND The impact of sarcopenia on quality of life is currently assessed by generic tools. However, these tools may not detect subtle effects of this specific condition on quality of life. OBJECTIVE The aim of this study was to develop a sarcopenia-specific quality of life questionnaire (SarQoL, Sarcopenia Quality of Life) designed for community-dwelling elderly subjects aged 65 years and older. SETTINGS Participants were recruited in an outpatient clinic in Liège, Belgium. SUBJECTS Sarcopenic subjects aged 65 years or older. METHODS The study was articulated in the following four stages: (i) Item generation-based on literature review, sarcopenic subjects' opinion, experts' opinion, focus groups; (ii) Item reduction-based on sarcopenic subjects' and experts' preferences; (iii) Questionnaire generation-developed during an expert meeting; (iv) Pretest of the questionnaire-based on sarcopenic subjects' opinion. RESULTS The final version of the questionnaire consists of 55 items translated into 22 questions rated on a 4-point Likert scale. These items are organised into seven domains of dysfunction: Physical and mental health, Locomotion, Body composition, Functionality, Activities of daily living, Leisure activities and Fears. In view of the pretest, the SarQoL is easy to complete, independently, in ∼10 min. CONCLUSIONS The first version of the SarQoL, a specific quality of life questionnaire for sarcopenic subjects, has been developed and has been shown to be comprehensible by the target population. Investigations are now required to test the psychometric properties (internal consistency, test-retest reliability, divergent and convergent validity, discriminant validity, floor and ceiling effects) of this questionnaire.

[PMID: 26291444 DOI: 10.1016/j.socscimed.2015.08.002] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2015] [Revised: 07/28/2015] [Accepted: 08/03/2015] [Indexed: 11/29/2022]
Abstract
There is growing interest in operationalising the capability approach to measure quality of life. This paper reports the results of a research project undertaken in 2007 that sought to reduce and refine a longer survey in order to provide a summary measure of wellbeing and capability in the realm of public health. The reduction and refinement of the questionnaire took place across a number of stages, using both qualitative (five focus group discussions and 17 in-depth interviews) and quantitative (secondary data analysis, N = 1048 and primary data collection using postal surveys and interviews, N = 45) approaches. The questionnaire was reduced from its original 60+ questions to 24 questions (including demographic questions). Each of Nussbaum's ten Central Human Capabilities are measured using one (or more) of the 18 specific capability items which are included in the questionnaire (referred to as the OCAP-18). Analysis of the questionnaire responses (N = 198) found that respondents differed with respect to the levels of capabilities they reported, and that these capabilities appear to be sensitive to one's gender, age, income and deprivation decile. An index of capability, estimated by assuming equal weight for each capability question, found that the average level of capability amongst respondents was 12.44 (range 3-17.75). This index was found to be highly correlated with a measure of health (EQ-5D) and wellbeing (global QoL), although some differences were apparent. This project operationalised the capability approach to produce an instrument to measure the effectiveness (and cost effectiveness) of public health interventions; the resulting OCAP-18 appears to be responsive and measure something supplementary to health and wellbeing, thus offers a promising addition to the current suite of outcome measures that are available.
