How to capture patients’ concerns and related changes: Comparing the MYCaW questionnaire, semi-structured interview and a priority list of outcome areas

Development of a core outcome set of clinical research on the integration of traditional Chinese and Western medicine for spinal metastases:

BACKGROUND

In recent years, the incidence of spinal metastasis (SM) has been increasing steadily. In response to this serious public health problem, researchers have made progress by using the integration of traditional Chinese and Western medicine. However, considerable heterogeneity in the definition and measurement of outcomes across clinical research studies, along with the lack of uniform measurement standards for study data, makes it difficult for researchers to compare different treatments. Therefore, it is crucial to accurately evaluate clinical research on the integration of traditional Chinese and Western medicine for SM.

METHODS

This study protocol outlines a comprehensive research programme based on the Core Outcome Set Standards Protocol Items. The study consists of four phases: a literature review, semistructured interviews, a two-round modified Delphi survey, a consensus meeting. Phase 1 involves a comprehensive literature review to extract outcomes used in current clinical studies of integrated traditional Chinese and Western medicine or Western medicine for the treatment of SM. A semistructured interview format will be used to survey patients and caregivers in phase 2 to collect suggestions from the patient perspective. Phase 3 involves a two-round modified Delphi survey to complete a prioritisation evaluation of outcomes to generate a candidate list for core outcome set (COS). Finally, phase 4 involves a face-to-face consensus meeting to review and establish the COS.

ETHICS AND DISSEMINATION

Conducted in response to the current dilemma of SM, the study was endorsed by the Spine Oncology Group of the Orthopaedic Surgeons Branch of the Chinese Physicians' Association. It will be developed and reported through a rigorous process, with the results of the study to be published in a peer-reviewed journal.Registration: COMET Registry: COMET 2938; https://www.comet-initiative.org/Studies/Details/2938.

Benefit of inhalation aromatherapy as a complementary treatment for stress and anxiety in a clinical setting – A systematic review

OBJECTIVE

The purpose of this systematic review is to ascertain the impact of inhalation aromatherapy on stress and anxiety in clinical settings.

METHODS

A search strategy was developed using various databases. Randomised Controlled Trials (RCTs) as well as single and double-blind pilot clinical studies (non-RCT) using inhalation aromatherapy with an essential oil blend or a single essential oil were examined. All studies included a control intervention and use of a validated measurement tool. The time period under review was years 2000-2021. Due to the high level of heterogeneity and element of bias, a narrative synthesis was conducted.

RESULTS

The search strategy initially retrieved 628 studies and through application of the selection criteria and the removal of duplicates, 76 studies were selected for review with a total of 6539 patients. In 42% of the RCTs, physiological measures including vital signs and/or salivary cortisol were used in addition to questionnaires. Over 70% of the studies reported a positive effect on anxiety levels in the aromatherapy intervention groups compared with the control. However, in many cases this is limited by the absence of safety data, imprecise reporting of plant species and dosage of essential oil.

CONCLUSION

Inhalation aromatherapy has the potential to reduce stress and anxiety with data emerging to further support this result across a wide modality of clinical treatments. However, there is a clear need for the development of standard protocols for research in this area, generating measurable results which will create the opportunity for more rigorous evidence-based outcomes.
