Effect of Adding Personalized Instant Messaging Apps to a Brief Smoking Cessation Model in Community Smokers in Hong Kong: Pragmatic Randomized Clinical Trial.

BACKGROUND: While text messaging has proven effective for smoking cessation (SC), engagement in the intervention remains suboptimal. OBJECTIVE: This study aims to evaluate whether using more interactive and adaptive instant messaging (IM) apps on smartphones, which enable personalization and chatting with SC advisors, can enhance SC outcomes beyond the provision of brief SC advice and active referral (AR) to SC services. METHODS: From December 2018 to November 2019, we proactively recruited 700 adult Chinese daily cigarette users in Hong Kong. Participants were randomized in a 1:1 ratio. At baseline, all participants received face-to-face brief advice on SC. Additionally, they were introduced to local SC services and assisted in selecting one. The intervention group received an additional 26 personalized regular messages and access to interactive chatting through IM apps for 3 months. The regular messages aimed to enhance self-efficacy, social support, and behavioral capacity for quitting, as well as to clarify outcome expectations related to cessation. We developed 3 sets of messages tailored to the planned quit date (within 30 days, 60 days, and undecided). Participants in the intervention group could initiate chatting with SC advisors on IM themselves or through prompts from regular messages or proactive inquiries from SC advisors. The control group received 26 SMS text messages focusing on general health. The primary outcomes were smoking abstinence validated by carbon monoxide levels of <4 parts per million at 6 and 12 months after the start of the intervention. RESULTS: Of the participants, 505/700 (72.1%) were male, and 450/648 (69.4%) were aged 40 or above. Planning to quit within 30 days was reported by 500/648 (77.2%) participants, with fewer intervention group members (124/332, 37.3%) reporting previous quit attempts compared with the control group (152/335, 45.4%; P=.04). At the 6- and 12-month follow-ups (with retention rates of 456/700, 65.1%, and 446/700, 63.7%, respectively), validated abstinence rates were comparable between the intervention (14/350, 4.0%, and 19/350, 5.4%) and control (11/350, 3.1% and 21/350, 6.0%) groups. Compared with the control group, the intervention group reported greater utilization of SC services at 12 months (RR 1.26, 95% CI 1.01-1.56). Within the intervention group, engaging in chat sessions with SC advisors predicted better validated abstinence at 6 months (RR 3.29, 95% CI 1.13-9.63) and any use of SC services (RR 1.66, 95% CI 1.14-2.43 at 6 months; RR 1.67, 95% CI 1.26-2.23 at 12 months). CONCLUSIONS: An IM-based intervention, providing support and assistance alongside brief SC advice and AR, did not yield further increases in quitting rates but did encourage the utilization of SC services. Future research could explore whether enhanced SC service utilization leads to improved long-term SC outcomes.

Effects of Palliative Care for Progressive Neurologic Diseases: A Systematic Review and Meta-Analysis.

OBJECTIVES: To determine the association of palliative care for progressive neurologic diseases with patient- and caregiver-centered outcomes. DESIGN: Systematic review and meta-analysis of randomized controlled trials and quasi-experimental studies, including pilot studies. SETTING AND PARTICIPANTS: Adults with progressive neurologic diseases (dementia, multiple sclerosis, Parkinson's disease, motor neuron disease, multiple system atrophy, and progressive supranuclear palsy) and their caregivers. METHODS: MEDLINE, EMBASE, CINAHL PLUS, Cochrane CENTRAL, and PubMed were searched from inception to September 2021. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Cochrane risk of bias tools. Narrative synthesis was conducted. Patient quality of life (QoL), symptom burden, caregiver burden, and satisfaction with care were meta-analyzed using a random-effects model. RESULTS: Fifteen trials provided data on 3431 patients (mean age, 73.9 years). Compared with usual care, palliative care was statistically significantly associated with lower symptom burden [standardized mean difference (SMD), -0.34 (95% Cl, -0.59 to -0.09)] and higher caregiver satisfaction [SMD, 0.41 (95% Cl, 0.12 to 0.71)] and patient satisfaction [SMD, 0.43 (95% Cl, -0.01 to 0.87)]. However, the associations were not significant after excluding studies with high risk of bias. Insignificant associations of palliative care with caregiver burden [SMD, -0.09 (95% Cl, -0.21 to 0.03)] and patient QoL [SMD, 0.19 (95% Cl, -0.07 to 0.44)] were observed. CONCLUSIONS AND IMPLICATIONS: Palliative care is likely to improve symptom burden and satisfaction with care among patients with progressive neurologic diseases and their caregivers, while its effects on QoL and caregiver burden remains inconclusive. Specific intervention components including interdisciplinary team, palliative care physicians, home visits, and spiritual care appeared to be associated with increased effects on improving palliative outcomes. More rigorous designed studies are warranted to examine the effects of neuropalliative care, effective intervention components, optimal timing, and symptom triggers of palliative care referrals.

Challenges of healthcare professionals in providing care to South Asian ethnic minority patients in Hong Kong: A qualitative study.

Ethnic minorities across the globe encounter disparities in healthcare. While a great deal of research has been conducted on the experiences of these patients, studies focusing on the perspectives of healthcare professionals are limited, particularly in the context of Asia. This study explores the perceptions of and challenges faced by Hong Kong healthcare professionals in the provision of culturally appropriate care to South Asian ethnic minority patients. Taking a qualitative approach, interviews were conducted with 22 healthcare professionals. Two main themes were identified: 'lack of support' at the healthcare system level and 'dysfunctional relationship with South Asian ethnic minority patients' at the interpersonal level. Challenges at the healthcare system level include information outreach, cultural competency, utilisation of available resources and time and workload, whereas challenges at the interpersonal level include patient-provider interaction, patient-provider perceptions of illness and care and patient-provider sociocultural discordance. Intercultural care was found to be influenced by both the healthcare system and interpersonal characteristics. The study highlights the need for healthcare professional education and training in cultural competency, in order to improve the provision of intercultural care. Identifying the challenges faced by healthcare professionals and the implications of these challenges for the provision of healthcare to South Asian ethnic minority patients will help practitioners, policy makers and care provider agencies to improve quality of care and health outcomes for culturally diverse patients.
