Developing a measure of medication-related quality of life for people with polypharmacy.

PURPOSE: To develop a measure of medication-related quality of life (MRQoL) and to validate the measure in a hospital-based population of patients with polypharmacy. METHODS: The Medication-Related Quality of Life Scale version 1.0 (MRQoLS-v1.0) included 14 items developed on the basis of interviews with elderly patients with polypharmacy, defined as taking five or more medications simultaneously. This scale was tested in 219 outpatients (99 with polypharmacy and 120 without polypharmacy). Two measures were used to establish construct validity the Psychological Distress Checklist, for convergent validity, and the Medication Adherence Behavior Scale (MABS), for discriminant validity. RESULTS: The 14-item scale was found to be both reliable and valid. Internal consistency reliability evaluated using Cronbach's alpha for this scale was 0.91. Scores on the MRQoLS-v1.0 correlated statistically significantly and negatively with those on the Psychological Distress Checklist. Discriminant validity was demonstrated by low correlation with MABS, indicating that the MRQoLS-v1.0 measured concepts different from medication adherence. Significant differences in the MRQoLS-v1.0 between patients with polypharmacy and those without polypharmacy provided evidence for known-group validity. CONCLUSIONS: The study presents a psychometric evaluation of a measure used to assess MRQoL of patients with polypharmacy. The instrument is practical to administer in clinics and provides a valuable adjunct to the outcome measurement for patients with polypharmacy. Further research on the sensitivity of this instrument to medication change in multi-medicated patients is warranted.

Construct validity of PROMIS pain interference, fatigue, and physical function as patient-reported outcomes in adults with idiopathic inflammatory myopathies: An international study from the OMERACT myositis working group.

BACKGROUND: Validated patient-reported outcome measures to assess disease impact in patients with adult idiopathic inflammatory myopathies (IIMs) are needed. The objective of this study was to assess the construct validity of PROMIS Pain Interference, Fatigue, and Physical Function measures in comparison with core disease activity measures. METHODS: Adults with IIM, excluding inclusion body myositis, from OMERACT Myositis Working Group (MWG) clinic sites completed PROMIS Short Form v1.0-Pain Interference 6a, PROMIS Short Form v1.0-Fatigue 7a, and PROMIS Short Form v2.0-Physical Function 8b measures. Core disease activity measures including patient and physician global disease activity assessments, manual muscle testing, serum creatine kinase activity, and Health Assessment Questionnaire Disability Index (HAQ-DI) were simultaneously assessed. To evaluate construct validity, a priori hypotheses for the expected correlations between PROMIS measures, age, and core disease measures were determined by >70 % agreement among MWG members and were compared against observed Pearson's correlations. Internal consistency of items and floor or ceiling effects for the PROMIS measures were also assessed. Subgroup analysis according to IIM subtype (dermatomyositis vs. non-dermatomyositis IIM) was performed. RESULTS: 135 adults with IIM from 5 countries across North America, Europe, Asia, and Australia were included. For construct validity, a priori hypotheses were confirmed for 5 of 6 (83 %) PROMIS Pain Interference, 4 of 5 (80 %) PROMIS Fatigue, and 3 of 4 (75 %) PROMIS Physical Function correlations. Internal consistency was high for each PROMIS measure (Cronbach's alpha >0.9). Ceiling effects were observed only for PROMIS Pain Interference, with low/no pain in 29 % of patients. Subgroup analysis between dermatomyositis (n = 65) and non-dermatomyositis (n = 70) subtypes demonstrated similar correlations between PROMIS measures and disease activity measures. CONCLUSIONS: PROMIS Short Form v1.0-Pain Interference 6a, PROMIS Short Form v1.0-Fatigue 7a, and PROMIS Short Form v2.0-Physical Function 8b measures demonstrate strong construct validity when compared to core disease activity measures in IIM, with consistent results across IIM subtypes. These findings support the use of these selected PROMIS measures to assess core domains of interest for measuring life impact in IIMs.

Re: Caron et al., 2021, sociocultural context and autistics quality of life: A comparison between Quebec and France.

LAY ABSTRACT: This letter to the editors discusses the use of the ASQoL for research with autistic adults. The autism quality of life measure was developed for use alongside two existing measures of quality of life developed by the World Health Organization. It was not developed as a questionnaire to be used in its own. The letter raises some concerns about the use of the autism quality of life measure as a standalone measure in a recent study by Caron et al., published in Autism.

Joint pain within adult middle-aged women, attending a community clinic in a peri-urban area in South Africa: a cross-sectional survey.

BACKGROUND: This study aimed to investigate the prevalence of joint pain in women between the ages of 40 and 64 years who attended a community clinic in the Free State to provide micro-information for health care planners. METHODS: A sample of convenience was utilized in the cross-sectional survey. Health care workers were recruited to conduct the survey. Outcome measures included the Community-Oriented-Programme-For-The-Control-Of-Rheumatic-Disease questionnaire and European Quality of Life - 5 Dimensions health related quality of life measure. Descriptive statistics were calculated for categorical data and non-parametric tests for ordinal data. Quality Adjusted Life Years lost were based on the preference weights generated by the European Quality of Life - 5 Dimensions. RESULTS: One thousand three hundred seventy-six participants were enrolled. The prevalence of joint pain experienced in either the short or the long term was 62.1% (CI 59.5-64.6%). The total number of Quality Adjusted Life Years lost in this sample was 41.4, that is a rate of 3008.7 (CI 2740-3310) per 100,000. CONCLUSION: Epidemiological transition seems to be rapidly taking place in South Africa and the prevalence of joint pain is considerable. Primary health care systems should develop a cost-effective approach to manage and identify joint pain and improve the health-related quality of life of those living with this. Implications for Rehabilitation Prevalence of joint pain is considerable. Consume large amounts of health and social resources. A protocol for routine screening should be developed in community clinics. Cost-effective approach to manage joint pain should be identified to improve healthrelated quality of life of individuals living with joint pain.

Treatment and functional outcomes of complex tibial fractures in children and adolescents using the Ilizarov method.

Aims: The aim of this study was to report the clinical, functional and radiological outcomes of children and adolescents with tibial fractures treated using the Ilizarov method. Patients and Methods: Between 2013 and 2016 a total of 74 children with 75 tibial fractures underwent treatment at our major trauma centre using an Ilizarov frame. Demographic and clinical information from a prospective database was supplemented by routine functional and psychological assessment and a retrospective review of the notes and radiographs. Results: Of the 75 fractures, 26 (35%) were open injuries, of which six (8%) had segmental bone loss. There were associated physeal injuries in 18 (24%), and 12 (16%) involved conversion of treatment following failure of previous management. The remaining children had a closed unstable fracture or significant soft-tissue compromise. The median follow-up was 16 months (7 to 31). All fractures united with a median duration in a frame of 3.6 months (interquartile range 3.1 to 4.6); there was no significant difference between the types of fracture and the demographics of the patients. There were no serious complications and no secondary procedures were required to achieve union. Health-related quality of life measures were available for 60 patients (80%) at a minimum of six months after removal of the frame. These indicated a good return to function (median Paediatric quality of life score, 88.0; interquartile range 70.3 to 100). Conclusion: The Ilizarov method is a safe, effective and reliable method for the treatment of complex paediatric tibial fractures. Cite this article: Bone Joint J 2018;100-B:396-403.

Central Sensitization Inventory as a Predictor of Worse Quality of Life Measures and Increased Length of Stay Following Spinal Fusion.

BACKGROUND: Central sensitization is abnormal and intense enhancement of pain mechanism by the central nervous system. Patients with central sensitization may be at higher risk of poor outcomes after spinal fusion. The Central Sensitivity Inventory (CSI) was developed to identify and quantify key symptoms related to central sensitization. METHODS: In 664 patients who underwent thoracic and/or lumbar fusion, we evaluated retrospectively pretreatment CSI as a predictor of postoperative quality of life measures, length of stay, and discharge status. RESULTS: Preoperative Pain Disability Questionnaire scores, Patient Health Questionnaire-9 scores, and EuroQol-5 Dimensions index scores were significantly worse in patients with preoperative CSI ≥40 compared with patients with preoperative CSI <40 (P < 0.0001 for all). After adjusting for demographic variables, operation duration, and preoperative health status, preoperative CSI was significantly associated with higher postoperative Pain Disability Questionnaire total score (unadjusted P < 0.001, adjusted P = 0.009), higher postoperative Patient Health Questionnaire-9 score (unadjusted P < 0.001, adjusted P = 0.001), and lower postoperative EuroQol-5 Dimensions index (unadjusted P < 0.001, adjusted P = 0.001). For each 10-unit increase in CSI, average length of stay increased by 6.4% (95% confidence interval 0.4%-12.6%, P = 0.035). The odds of being discharged home after adjusting for confounders was not statistically related to preoperative CSI (P = 0.0709). CONCLUSIONS: Preoperative CSI was associated with worse quality of life outcomes and increased length of stay after spinal fusions. CSI may be an additional measure in evaluating patients preoperatively to better predict successful spinal fusion outcomes.

Criterion validity, reliability and clinical responsiveness of the CareConnections Functional Index.

This study established the criterion validity, test-retest reliability and responsiveness of the CareConnections Functional Index (CCFI). The CCFI is composed of four body-region specific subscales, measuring functional ability. Reference standards included the Neck Disability Index; Modified Oswestry Disability Index; Quick Disabilities of the Arm, Shoulder and Hand and the Lower Extremity Functional Scale. One hundred subjects per body region were enrolled. Subject's rated their perceived improvement based on the 15-point Global Rating of Change questionnaire. Minimal clinically important differences (MCID) were calculated via receiver operator characteristic curve. Test-retest reliability coefficients were good to excellent. Validity correlations with the reference standard measures were acceptable (r > 0.7) for all subscales. MCID for the cervical subscale = 7 points, lumbar = 8 points, upper extremity = 16 points and lower extremity = 11 points. The results of this study support the use of the CCFI in outpatient physical therapy practice as a responsive tool with good reliability and validity. The results also indicate that future work should focus on the impact of baseline patient factors that may affect future outcome.

Predicting health utilities for children with autism spectrum disorders.

Comparative effectiveness of interventions for children with autism spectrum disorders (ASDs) that incorporates costs is lacking due to the scarcity of information on health utility scores or preference-weighted outcomes typically used for calculating quality-adjusted life years (QALYs). This study created algorithms for mapping clinical and behavioral measures for children with ASDs to health utility scores. The algorithms could be useful for estimating the value of different interventions and treatments used in the care of children with ASDs. Participants were recruited from two Autism Treatment Network sites. Health utility data based on the Health Utilities Index Mark 3 (HUI3) for the child were obtained from the primary caregiver (proxy-reported) through a survey (N = 224). During the initial clinic visit, proxy-reported measures of the Child Behavior Checklist, Vineland II Adaptive Behavior Scales, and the Pediatric Quality of Life Inventory 4.0 (start measures) were obtained and then merged with the survey data. Nine mapping algorithms were developed using the HUI3 scores as dependent variables in ordinary least squares regressions along with the start measures, the Autism Diagnostic Observation Schedule, to measure severity, child age, and cognitive ability as independent predictors. In-sample cross-validation was conducted to evaluate predictive accuracy. Multiple imputation techniques were used for missing data. The average age for children with ASDs in this study was 8.4 (standard deviation = 3.5) years. Almost half of the children (47%) had cognitive impairment (IQ ≤ 70). Total scores for all of the outcome measures were significantly associated with the HUI3 score. The algorithms can be applied to clinical studies containing start measures of children with ASDs to predict QALYs gained from interventions.
