Abstract
Introduction: Behavioral and psychological symptoms of dementia (BPSD) is the most prominent and distressing manifestation for older persons with dementia (PWD) and caregivers. Aromatherapy has demonstrated its effectiveness in managing BPSD in various studies. However, previous studies and systematic reviews have obtained inconsistent findings, and a review of qualitative studies is yet to be conducted.
Method: A mixed-methods systematic review with a convergent segregated approach was performed to evaluate the effectiveness of aromatherapy in improving the BPSD and quality of life (QoL) of PWD and in relieving the distress and burden of caregivers, as well as its safety for PWD. Both published and unpublished quantitative and qualitative studies written in English and Chinese between January 1996 and December 2020 were retrieved from 28 databases, including MEDLINE, EMBASE, and Web of Science, based on the prespecified criteria. The methodological quality was assessed by using critical appraisal tools from the Joanna Briggs Institute. Quantitative synthesis, qualitative synthesis, and integration of quantitative and qualitative evidence were performed.
Results: A total of 12 randomized controlled trials, 10 quasi-experimental studies, and 2 qualitative studies were included in the review. Some inconsistent findings regarding the effectiveness of aromatherapy in reducing the severity of BPSD were observed. Some studies reported that aromatherapy significantly improved the QoL of PWD and relieved the distress and burden of caregivers, promoted a positive experience among caregivers, and had very low adverse effects on PWD (with aromatherapy inhalation reporting no adverse effects).
Conclusion: Aromatherapy, especially in the inhalation approach, could be a potentially safe and effective strategy for managing BPSD. However, more structuralized and comparable studies with sufficient sample size, adherence monitoring, and sound theoretical basis could be conducted to obtain conclusive findings.
引言：痴呆症（BPSD）的行为和心理症状是老年痴呆症（PWD）患者和护理人员最突出和最痛苦的表现。芳香疗法已在各种研究中证明其在管理BPSD方面的有效性。然而，先前的研究和系统综述获得了不一致的结果，定性研究的综述尚待进行。方法：采用融合-分离的混合方法进行系统评价，以评估芳香疗法在改善PWD的BPSD和生活质量（QoL）、减轻护理人员的痛苦和负担方面的有效性及其对PWD的安全性。根据预先指定的标准，从MEDLINE、EMBASE和Web of Science等28个数据库中检索1996年1月至2020年12月期间已发表和未发表的中英文定量和定性研究。方法学质量是通过使用乔安娜·布里格斯研究所的关键评估工具进行评估的。进行了定量合成、定性合成以及定量和定性证据的整合。结果：共纳入12项随机对照试验、10项准实验研究和2项定性研究。关于芳香疗法在降低BPSD严重程度方面的有效性，观察到了一些不一致的发现。一些研究报告称，芳香疗法显著改善了PWD的生活质量，减轻了照顾者的痛苦和负担，促进了照顾者之间的积极体验，并且对PWD的不良反应非常低（吸入芳香疗法报告没有不良反应），这可能是一种潜在的安全有效的BPSD管理策略。然而，可以进行更结构化和可比较的研究，具有足够的样本量、依从性监测和完善的理论基础，以获得结论性的发现。
