Outcomes and outcomes measurements used in intervention studies of pelvic girdle pain and lumbopelvic pain: a systematic review.

ABSTRACT: Background:Pelvic girdle pain is a common problem during pregnancy and postpartum with significant personal and societal impact and costs. Studies examining the effectiveness of interventions for pelvic girdle pain measure different outcomes, making it difficult to pool data in meta-analysis in a meaningful and interpretable way to increase the certainty of effect measures. A consensus-based core outcome set for pelvic girdle pain can address this issue. As a first step in developing a core outcome set, it is essential to systematically examine the outcomes measured in existing studies. Objective:The objective of this systematic review was to identify, examine and compare what outcomes are measured and reported, and how outcomes are measured, in intervention studies and systematic reviews of interventions for pelvic girdle pain and for lumbopelvic pain (which includes pelvic girdle pain). Methods:We searched PubMed, Cochrane Library, PEDro and Embase from inception to the 11th May 2018. Two reviewers independently selected studies by title/abstract and by full text screening. Disagreement was resolved through discussion. Outcomes reported and their outcome measurement instruments were extracted and recorded by two reviewers independently. We assessed the quality of reporting with two independent reviewers. The outcomes were grouped into core domains using the OMERACT filter 2.0 framework. Results:A total of 107 studies were included, including 33 studies on pelvic girdle pain and 74 studies on lumbopelvic pain. Forty-six outcomes were reported across all studies, with the highest amount (26/46) in the 'life impact' domain. 'Pain' was the most commonly reported outcome in both pelvic girdle pain and lumbopelvic pain studies. Studies used different instruments to measure the same outcomes, particularly for the outcomes pain, function, disability and quality of life. Conclusions:A wide variety of outcomes and outcome measurements are used in studies on pelvic girdle pain and lumbopelvic pain. The findings of this review will be included in a Delphi survey to reach consensus on a pelvic girdle pain - core outcome set. This core outcome set will allow for more effective comparison between future studies on pelvic girdle pain, allowing for more effective translation of findings to clinical practice.

Project description:IntroductionPelvic girdle pain during and after pregnancy is a major public health problem with significant daily problems for affected women and their families. There is now accumulating evidence that pregnancy-related pelvic girdle pain originates from the sacroiliac joints and the pubic symphysis as well as their extra-articular ligaments. However, the heritability of the disease remains to be determined. We hypothesized that there is an increased familial risk of pregnancy-related pelvic girdle pain.Material and methodsA population-based national database linkage registry study of approximately 9.3 million individuals within 4.2 million families in Sweden with a recruitment period from 1997 to 2018. The Swedish Multi-generation register was used to find female pairs of twins, full siblings, half-siblings and first cousins where both in the pairs had a completed pregnancy. The outcome measure was diagnosis of pregnancy-related pelvic girdle pain (International Classification of Diseases-10 O26.7 [1997-2018]) in the first pregnancy. Data was obtained from the Swedish Hospital Discharge Register, the Swedish Outpatient Care Register, the Swedish Medical Birth Register, the Primary Healthcare Register, and Medical Treatment Register. Cox regression analysis was used to calculate adjusted estimated effect of the exposure variable familial history of pregnancy-related pelvic girdle pain on the outcome variable pregnancy-related pelvic girdle pain at first birth.ResultsFrom the registers, 1 010 064 women pregnant with their first child within 795 654 families were collected. In total, 109 147 women were diagnosed with pregnancy-related pelvic girdle pain. The adjusted hazard ratio for a familial risk of pregnancy-related pelvic girdle pain was 2.09 (95% CI 1.85-2.37) among twins (monozygotic and dizygotic), 1.78 (95% CI 1.74-1.82) in full siblings, 1.16 (95% CI 1.06-1.28) in half-siblings from the mother, 1.09 (95% CI 1.024-1.16) in half-siblings from the father and 1.09 (95% CI 1.07-1.12) in first cousins.ConclusionsThis nationwide observational study showed a familial clustering of pregnancy-related pelvic girdle pain. The hazard ratio for the condition was associated with the degree of relatedness, suggesting that heredity factors contribute to the development of pregnancy-related pelvic girdle pain. There is no causal treatment available for pregnancy-related pelvic girdle pain and further studies are now encouraged to clarify the specific genetic factors that contribute to the disease and for future targeted interventions.

Project description:IntroductionLumbopelvic pain (LPP) is common in pregnant women and has a significant negative effect on physical and psychological health. In this study, for the first time, we conduct a meta-analysis to estimate the overall prevalence of LPP among pregnant women and clarify the reasons for the differences in the estimated results.Material and methodsA systematic search of four databases (PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials) was conducted from inception until October 2022. Two reviewers conducted a methodological quality assessment. Random-effects model analysis was used to estimate the pooled prevalence and the 95% confidence interval. Chi-square tests and I2 -values were used to assess the heterogeneity. Subgroup analysis (according to the participants' continent, age, body mass index [BMI], gestational age and study risk of bias), sensitivity analysis and random-effects meta-regression were used to explore the the sources of heterogeneity.ResultsOf the 1661 unique citations, 38 studies (21 533 pregnant participants) were included in this systematic review and meta-analysis. The overall pooled prevalence of LPP during pregnancy was 63% (95% CI: 0.57 to 0.69), with significant heterogeneity (I2 = 99.1%, P < 0.001). The prevalence differed by participants' continents, 71% (North America), 74% (South America), 63% (Asia), 64% (Europe), 59% (Africa) and 45% (Oceania). The prevalence differed by BMI, 64% (BMI <25), 64% (25 ≤ BMI ≤ 28), and 71% (BMI >28). The prevalence differed by age, 72% (age <25 years), 58% (25 ≤ age ≤ 30 years), and 69% (age >30 years). The prevalence were the same differed by study risk of bias, 63% (both low and moderate risk of bias studies). The prevalence were similar by gestational age, 62% (second trimester) and 63% (third trimester).ConclusionsLumbopelvic pain during pregnancy is common; about three-fifths of pregnant women experience LPP. More prevention and intervention research for lumbopelvic should be conducted in pregnant women with different clinical characteristics.

Project description:BackgroundPelvic Girdle Pain (PGP) is an important cause of disability and economic cost worldwide. There is a need for effective preventative and management strategies. Emerging studies measure a variety of outcomes rendering synthesis and translation to clinical practice difficult. A Core Outcome Set (COS) can address this problem by ensuring that data are relevant, useful and usable for making well-informed healthcare choices. The aim of this study is to develop a consensus-based PGP-COS, including agreement on methods (e.g. instruments) for measuring the construct outcomes in the COS for use in research and clinical practice. Furthermore, as there is uncertainty as to whether incorporating stakeholder interviews in addition to conducting a systematic review to determine an initial list of outcomes for the Delphi survey, or, whether using different rating scales in a Delphi survey impacts on the final COS, we propose to embed two methodological studies within the PGP-COS development process to address these questions.MethodsThe PGP-COS study will include five phases: (1) A systematic review of the literature and semi-structured interviews with 15 patients (three countries) to form the initial list of outcomes for the Delphi survey; (2) A 3-round Delphi including patients, clinicians, researchers and service providers; (3) A systematic review of methods for measuring the outcomes in the preliminary PGP-COS identified in the Delphi survey; (4) A face-to-face consensus meeting to agree on the final PGP-COS and methods for measuring the COS; (5) Global dissemination. To address the methodological questions, we will assess the number and type of outcomes, in the final PGP-COS, that were exclusively derived from the interviews. Secondly, we will randomise Delphi survey participants to either a 5-point or 9-point importance rating scale, and examine potential differences in 'important' ratings between the groups.DiscussionThere is currently no COS for measuring/monitoring PGP in trials and clinical practice. A PGP-COS will ensure that relevant outcomes are measured using appropriate measurement instruments for patients with PGP globally.Core outcome set registrationThis PGP-COS was registered with COMET (Core Outcome Measures for Effectiveness Trials) in January 2017 ( http://www.comet-initiative.org/studies/details/958 ).
