Cross-cultural adaption and validation of the Swedish version of the Core Outcome Measures Index for low-back pain

Minimal clinical datasets for spine-related musculoskeletal disorders in primary and outpatient care settings: a scoping review

OBJECTIVES

Effective measurement and monitoring of health status in patients with spine-related musculoskeletal (MSK) disorders are essential for providing appropriate care and improving outcomes. Minimal clinical datasets are standardized sets of key data elements and patient-centered outcomes that can be measured and recorded during routine clinical care. Our scoping review aimed to identify and map current evidence on minimal clinical datasets for measuring and monitoring health status in patients with spine-related MSK disorders in primary and outpatient healthcare settings.

STUDY DESIGN AND SETTING

We followed the JBI (formerly Joanna Briggs Institute) methodology for scoping reviews. MEDLINE, CINAHL, Cochrane Library, Index to Chiropractic Literature, MANTIS, ProQuest Dissertations and Theses Global, and medRxiv preprint repository were searched from database inception to August 1, 2021. Two reviewers independently screened titles and abstracts, full-text articles, and charted the evidence. Findings were synthesized and summarized descriptively.

RESULTS

After screening 5,583 citations and 301 full-text articles, 104 studies about 32 individual minimal clinical datasets were included. Most minimal clinical datasets were developed for patient populations with spine-involving inflammatory arthritis, nonspecific or degenerative spinal pain, and MSK disorders in general. The minimal clinical datasets varied substantially in terms of the author-reported time-to-complete (1-48 minutes) and the number of items (5-100 items). Fifty percent of the datasets involved healthcare professionals in their development process, and only 28% involved patients. Health domain items were most frequently linked to the components of activities and participation (43.9%) and body functions (28.6%), according to the International Classification of Functioning, Disability, and Health. There is no standardized definition of minimal clinical datasets to measure and monitor health status of patients with spine-related MSK disorders in routine clinical practice. Common core elements identified were practicality, feasibility in a busy routine practice, time efficiency, and the capability to be used across different healthcare settings.

CONCLUSION

Due to the absence of a standard definition for minimal clinical datasets for patients with spine-related MSK disorders, there is a lack of consistency in the selection of key data elements and patient-centered outcomes that should be included. More research on the implementation and feasibility of minimal clinical datasets in routine care settings is warranted and needed. It is essential to involve all relevant partners in the development process of minimal clinical datasets to ensure successful implementation and adoption in routine primary care.

The Swedish version of the STarT MSK Tool: cross-cultural adaption, test-retest reliability, and aspects of validity

BACKGROUND

Musculoskeletal disorders (MSDs) are a common reason for seeking primary health care. The STarT Musculoskeletal (MSK) tool is designed to stratify patients suffering from MSDs to risk groups, based on prognostic factors.

AIM

The aim was to translate and cross-culturally adapt the STarT MSK tool in a Swedish primary health care context through testing of reliability and construct validity.

METHODS

We included consecutive patients with MSDs seeking primary care (n = 99). The STarT MSK was translated using international recommendations. Construct validity was investigated by correlation analysis (Spearmans Rho) with the following reference instruments: the Örebro Musculoskeletal Pain Questionnaire (ÖMPQ), the EuroQol 5-dimension (EQ-5D) and the Musculoskeletal Health Questionnaire (MSKHQ). Reliability was tested using test-retest (Intra Class Correlation, ICC2.1) (n = 31). Known-groups validity was calculated with a difference of 10% between risk groups based on how the participants had answered.

RESULTS

The STarT MSK was successfully translated into Swedish. The participants were grouped into low risk (n = 28), medium risk (n = 60) and high risk (n = 11). The construct validity showed a moderate to high correlation with the ÖMPQ (r = .61), EQ-5D (r = .59) and MSK-HQ (r = .56). All separate items except item 2 and 9 correlated according to predefined hypotheses. Test-retest demonstrated an excellent reliability for the total score (ICC2.1 0.85) (n = 31). The STarT MSK tool was able to differentiate by 10% between the risk groups, based on how the participants had answered.

CONCLUSION

The STarT MSK has been successfully translated and adapted into Swedish and shows acceptable measurement properties regarding test-retest reliability and aspects of validity and seems to be able to discriminate between the proposed risk groups. The tool can therefore be useful in a Swedish primary health care context. A future study needs to determine the tools predictive validity and to investigate if stratification to risk groups leads to a faster recovery and to lower health care costs.

Cross-cultural adaptation and validation of the Traditional Chinese version of the Core Outcome Measures Index in patients with low back pain

PURPOSE

This study aimed to carry out a cross-cultural adaptation of the Core Outcome Measures Index (COMI) for use in Traditional Chinese-speaking patients with low back pain (LBP) and to investigate its psychometric properties.

METHODS

A total of 224 patients with LBP > 6 weeks who visited our spine center from May 2018 to May 2019 were included in the study. Patients completed a booklet of questionnaires including the following: (1) pain Numeric Rating Scale, (2) Oswestry Disability Index, (3) Roland-Morris Disability Questionnaire, (4) EuroQol-five dimension (EQ-5D), and (5) COMI. Patients were sent a second booklet (also containing a transition question to indicate any change in condition) to be completed again within one month after the first. Fifty-two patients did not receive any intervening treatment (group 1), while the other 172 patients received medical treatment (group 2) between the two questionnaires.

RESULTS

The intraclass correlation coefficient (ICC) for the COMI summary score was 0.94 (95% CI 0.89-0.97); the standard error of measurement (SEM) was 0.41 and the minimum detectable change (MDC) score was 1.14. The COMI summary scores showed a low floor effect (1.8%) and ceiling effect (0.4%). All COMI item scores demonstrated the hypothesized correlations with their corresponding full-length questionnaires except for the pain item (correlation stronger than hypothesized). Standardized response means (SRM) for the COMI items in the treated group were between 0.58 and 1.30. Regarding the ability of the COMI change score to differentiate between good and poor outcomes, the area under the receiver operating characteristic (AUROC) curve was 0.77 [standard error (SE) 0.07, 95% confidence interval (CI) 0.68-0.84] and the minimal clinically important change (MCIC) score was ≥ 1.85 points.

CONCLUSION

The Traditional Chinese COMI represents a practical and reliable tool for the assessment of Traditional Chinese-speaking patients with back problems.

Are patient reported outcome measures (PROMs) useful in low back pain? Experiences of physiotherapists in primary health care in Sweden

BACKGROUND

Physiotherapists in primary health care are required to use patient reported outcome measures (PROMs) to manage patients with low back pain (LBP).

OBJECTIVE

Our aim was to explore and describe how physiotherapists in primary care managing patients with LBP, experience the use of PROMs with a focus on facilitating and hindering factors.

METHODS

We undertook a qualitative study with semi-structured interviews. Fifteen physiotherapists (9 female and 6 male) were included. The interviews were audio-recorded and transcribed verbatim and analysed by inductive manifest content analysis.

RESULTS

Our findings resulted in eight main categories: PROMs give structure and increase patient involvement; Patients' motivations to use PROMs; Time and the physiotherapist's clinical priorities; Physiotherapists' routines steer their use of PROMs; Physiotherapists' competences in using PROMs; Organizations and managers steer the use of PROMs; Prerequisites for future use of PROMs; Using PROMs develops the physiotherapy profession.

CONCLUSION

Our findings show that using PROMs gives structure and increases patient involvement, but the patient's motivation to use PROMs needs to be taken into consideration. Time and routines influence the use of PROMs and these factors depend on organizational and managerial levels. Using PROMs is believed to help develop the physiotherapy profession. Prerequisites for future use, such as digitalization and increased competence, need to be fulfilled. Future studies should focus on increasing physiotherapists' knowledge about relevant PROMs, and study implementation in clinical practice, thereby improving the physiotherapy profession's quality of care.

Cross-cultural adaptation and validation of the Arabic version of the Core Outcome Measures Index for the back (COMI-back) in patients with non-specific low back pain

PURPOSE

To cross-culturally adapt the Core Outcome Measures Index for the back (COMI-back) for the Arabic language and to test its reliability and validity in Egyptian patients with non-specific low back pain (LBP).

METHODS

COMI-back was translated and cross-culturally adapted into Arabic according to standard guidelines. Its construct validity was assessed in 85 patients with chronic LBP (mean (± SD) age, 41.1 (± 10.4) years and 65/85 (76.5%) female) who completed a booklet of questionnaires including the Arabic versions of COMI-back, Roland Morris disability questionnaire, Oswestry disability index, the short form health survey 36, and the visual analogue scale for back pain. Test-retest reliability was assessed in 52 participants who completed the booklet again within 7 days.

RESULTS

Floor effects (worst status; 1.2-10.6%) and ceiling effects (best status; 1.2-11.8%) for COMI-back were acceptable, except for symptom-specific well-being (18.8%, floor), leg pain (23.5%, ceiling), and work disability (31.8%, ceiling). The COMI item scores correlated with those of the reference questionnaires (ρ = 0.45-0.88) to the hypothesized extent, except for the COMI symptom-specific well-being (ρ = 0.16-0.17) and quality of life (ρ = 0.38). The intra-class correlation coefficient for the summary score was 0.90, whereas that of the individual items ranged from 0.71-0.92. The standard error of measurement and minimal detectable change for the summary score were 0.51 and 1.41 points, respectively. The predefined hypotheses for construct validity and reliability were largely confirmed.

CONCLUSION

The Arabic version of COMI-back represents a valid and reliable instrument for use in Arabic-speaking patients with non-specific LBP.
