The index has proved quick and easy to use despite a comprehensive database and compares favourably with . According to the OMERACT, face validity is the degree to which the instrument appears to match with the target domain, according to experts [18]. Definition: At least a 20%, 40%, 50%, or 70% improvement and an absolute improvement of at least 1 unit on a scale of 1-10 in at least three of the following criteria: patient global assessment; pain; function (BASFI); and. , Sato JO It should be noted that the PGA correlates with several other instruments that measure disease activity. In one study [25], the PGA of disease activity resulted from the combination of the clinical visit, laboratory markers evaluation and the physicians knowledge of the patient disease history. , Henriques C Meta-analysis of the studies reporting data concerning the construct validity between the PGA and SLEDAI. , Carpenter AB For instance, in an analysis of studies of the prevalence of SLE in the Asia-Pacific region, higher rates of renal involvement were observed in Asian patients (21-65% at SLE diagnosis and 40 . , Navarra SV Objectives Remission in systemic lupus erythematosus (SLE) is defined through a combination of 'clinical SLE Disease Activity Index (cSLEDAI)=0', 'physician's global assessment (PGA) <0.5 . , Schirmbeck LA Objective: The results are similar, and less than half the time is required for scoring. Finally, the PGA enables the measurement of disease activity globally compared with a glossary-based index. Of note, it is not trivial that we found a good convergent validity with other instruments (SLEDAI, BILAG, LAI, SLAM and ECLAM) [10, 23, 24, 26, 28, 29, 35, 54, 68, 76, 84, 99].

Content validity was reported in 89 studies. et al. In one open-label study [43], the decrease in PGA score was considered the primary endpoint. Barr et al. et al. , Chan KL Quimby KR , Matos A . , Birmingham DJ The responsiveness of the PGA is the ability to detect worthwhile variations in disease activity over time, measuring worsening or improvements in SLE disease status. The PGA is intended to encapsulate the physician's judgement of overall disease activity.Consensus on whether the PGA should be performed prior to, or after the receipt of laboratory values is lacking. This is a top barrier, both for treat-to-target management of SLE patients in clinical practice, as well as in clinical trials for new SLE treatments. et al.

Beaton DE CareerBuilder TIP. , Pilkington C Bookshelf , Magder LS The PGA is a valid instrument but has variable reliability; its scoring should be standardized. , McGwin G et al. SLE is an immune-mediated multisystemic disease characterized by a wide variability of clinical manifestations and a course frequently subject to unpredictable flares [1, 2]. , Wallace DJ , Dyer JW An acceptable reliability is indicated by values of intraclass correlation coefficient (ICC) or weighted >0.60 and a good reliability is >0.85 [20]. The assessment of disease activity in SLE is particularly challenging. Over the years, PGA-IGA scales were modified for the purpose of clinical settings and thus present a diversity in the number of response options (4 to 10 points), the response options label and the . The literature search identified 93 articles, and 12 additional articles were retrieved from the reference list of those publications. According to the authors, this difference was probably due to the greater familiarity of the physicians with the BILAG-2004 index. Higher disease activity is an important predictor of both organ damage and mortality [2] and the attainment of low disease activity is associated with a reduction in early damage [5, 6]. Conclusion: , Weisman MH. Int J Environ Res Public Health. This suggests that the role of the PGA is limited for disease activity assessment when used as a single instrument. , Ibaez D , Jolly M. Antony A This potentially disfiguring disease can have significant impact on patient's quality of life (QoL) and is often refractory to many first- and second-line therapies. It estimates how similar a given patients scores were at the two visits. The Physician Global Assessment (PGA) has been shown to be a valid, responsive, and feasible instrument to capture disease activity in systemic lupus erythematosus (SLE), but its low reliability further supports the need for a standardisation of its scoring. SLE or at an SLE site, but only if the injury requires treatment by a licensed medical doctor. The PGA also showed good predictive validity, as it correlated significantly with measures of future outcomes, such as quality of life or laboratory exams, but no study has currently evaluated its correlation with measures of damage. In the absence of a well-recognized gold standard for disease activity, criterion validity of the PGA is established when it correlates with a measure that the author of the study defined a priori as the gold standard. Exagen's products are used for therapeutic drug monitoring of hydroxychloroquine in whole blood and methotrexate polyglutamates, risk assessment testing, anti-TNF monitoring to individualize therapy and optimize dosing, and others. Few studies reported on whether serological activity should be incorporated in the PGA. A 21-numbered circle visual analog scale (VAS) may be a desirable alternative to the traditional 10-cm horizontal line for pain and patient global estimate on a Multidimensional Health Assessment Questionnaire (MDHAQ). Moreover, a difference between the interRR of the PGA assessed by an untrained physician (0.50.63) and a trained investigator (0.790.81) was found, suggesting the need for PGA scoring training or standardization [36]. , Holland M , Brunetta P The index assesses separately eight organ-based systems. independently selected the articles, initially on the basis of titles and abstracts, then, if necessary, on the full texts, an eligibility assessment was performed independently in a blinded standardized manner. , Adamichou C Of note, the literature search revealed heterogeneous definitions of physician assessment of disease activity other than the PGA (physician global assessment [4, 70, 73], physician overall assessment [85]). The literature search identified 91 studies. et al. , Voskuyl A Aranow C MeSH In support of its face validity, the PGA was used to define the disease activity score in all 91 studies retrieved by the literature search, having a role as an outcome measure as well as a comparator to assess the validity of other indices. All articles published through 1 July 2019 in PubMed were screened, with no limitation on year of publication, language or patients' age. , Cappellazzo G In Fatemi et al. The Physician Global Assessment International Standardisation COnsensus in Systemic Lupus Erythematosus (PISCOS) study aimed to obtain an evidence-based and expert-based consensus standardisation of the Physician Global Assessment (PGA) scoring of disease activity in systemic lupus erythematosus (SLE). A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines [17], searching for articles reporting on the use of PGA in SLE. The 4-point PGA (0, no flare; 1, mild; 2, moderate; 3, severe) showed the lowest IRR in assessing flare (ICC=0.18) compared with the BILAG-2004 (ICC=0.54) and SFI (ICC=0.21) [65]. , Vogel-Claussen J Touma Z To increase its reliability, the PGA should be scored by a physician with significant expertise in SLE, with prior knowledge of laboratory results [112], considering the overall disease activity at the time of the visit and comparing it to the last visit in order to assess flares [9]. 2014 Dec;53(12):2175-81. doi: 10.1093/rheumatology/keu153. Akhter E Changes in the PGA correlated with changes of other disease activity indices (SLEDAI, SLAM, LAI, patient global assessment), laboratory exams (ESR), patient-reported outcomes (Lupus Impact Tracker) [23, 50, 58, 77, 78, 81, 83] and response to treatment [4]. At least 1 issue from each virtual tour. PGA is a simple instrument and the result is easily understood. Disagreements between investigators were solved by consensus. , Block JA This scoring modality was used for the SRI [3]. The PGA is a well accepted and commonly used scale for evaluating treatment response in clinical trials both in adults and children. Methods This SLR was conducted by two independent reviewers in accordance with the PRISMA statement. , Perneger T , Klein-Gitelman MS , Allen E , Floris A et al.
