    (Journal of general internal medicine, 2021-09) Peh, Kai Qi Elizabeth; Kwan, Yu Heng; Goh, Hendra; Ramchandani, Hasna; Phang, Jie Kie; Lim, Zhui Ying; Loh, Dionne Hui Fang; Østbye, Truls; Blalock, Dan V; Yoon, Sungwon; Bosworth, Hayden Barry; Low, Lian Leng; Thumboo, Julian

    Objective

    To summarize the available conceptual models for factors contributing to medication adherence based on the World Health Organization (WHO)'s five dimensions of medication adherence via a systematic review, identify the patient groups described in available conceptual models, and present an adaptable conceptual model that describes the factors contributing to medication adherence in the identified patient groups.

    Methods

    We searched PubMed®, Embase®, CINAHL®, and PsycINFO® for English language articles published from inception until 31 March 2020. Full-text original publications in English that presented theoretical or conceptual models for factors contributing to medication adherence were included. Studies that presented statistical models were excluded. Two authors independently extracted the data.

    Results

    We identified 102 conceptual models, and classified the factors contributing to medication adherence using the WHO's five dimensions of medication adherence, namely patient-related, medication-related, condition-related, healthcare system/healthcare provider-related, and socioeconomic factors. Eight patient groups were identified based on age and disease condition. The most universally addressed factors were patient-related factors. Medication-related, condition-related, healthcare system-related, and socioeconomic factors were represented to various extents depending on the patient group. By systematically examining how the WHO's five dimensions of medication adherence were applied differently across the eight different patient groups, we present a conceptual model that can be adapted to summarize the common factors contributing to medication adherence in different patient groups.

    Conclusion

    Our conceptual models can be utilized as a guide for clinicians and researchers in identifying the facilitators and barriers to medication adherence and developing future interventions to improve medication adherence.

    Experience and Perceptions of a Family Health History Risk Assessment Tool among Multi-Ethnic Asian Breast Cancer Patients.
    (J Pers Med, 2021-10-19) Yoon, Sungwon; Goh, Hendra; Fung, Si Ming; Tang, Shihui; Matchar, David; Ginsburg, Geoffrey S; Orlando, Lori A; Ngeow, Joanne; Wu, Rebekah Ryanne
    A family health history-based risk assessment is particularly valuable for guiding cancer screening and treatment strategies, yet an optimal implementation depends upon end-users' values and needs. This is not only true prior to disease development, but also for those already affected. The aim of this study is to explore perceptions of the value of knowing one's family health history (FHH)-based risk, experience using a patient-facing FHH tool and the potential of the tool for wider implementation. Twenty multi-ethnic Asian patients undergoing breast cancer treatment in Singapore completed an FHH-based risk assessment. Semi-structured one-on-one interviews were conducted and data were thematically analyzed. All participants were female and slightly more than half were Chinese. The acceptance and usage of an FHH risk assessment tool for cancers and its broader implementation was affected by a perceived importance of personal control over early detection, patient concerns of anxiety for themselves and their families due to risk results, concerns for genetic discrimination, adequacy of follow-up care plans and Asian cultural beliefs toward disease and dying. This study uniquely sheds light on the factors affecting Asian breast cancer patients' perceptions about undergoing an FHH-based risk assessment, which should inform steps for a broader implementation in Asian healthcare systems.

    Impact of COVID-19 on perceived wellbeing, self-management and views of novel modalities of care among medically vulnerable patients in Singapore.
    (Chronic illness, 2021-12-29) Yoon, Sungwon; Hoe, Pei Shan; Chan, Angelique; Malhotra, Rahul; Visaria, Abhijit; Matchar, David; Goh, Hendra; Seng, Bridget; Ramakrishnan, Chandrika; Koh, Mariko S; Yee, Tiew Pei; Nadarajan, Gayathri Devi; Bee, Yong Mong; Graves, Nicholas; Jafar, Tazeen H; Ong, Marcus Eh

    Objectives

    This study aims to examine the impact of COVID-19 measures on wellbeing and self-management in medically vulnerable non-COVID patients and their views of novel modalities of care in Singapore.

    Methods

    Patients with cardiovascular disease (CVD), respiratory disease, chronic kidney disease, diabetes and cancer were recruited from the SingHealth cluster and national cohort of older adults. Data on demographics, chronic conditions and perceived wellbeing were collected using questionnaire. We performed multivariable regression to examine factors associated with perceived wellbeing. Qualitative interviews were conducted to elicit patient's experience and thematically analyzed.

    Results

    A total of 91 patients participated. Male patients compared with female patients perceived a lower impact of the pandemic on subjective wellbeing. Patients with CVD compared to those having conditions other than CVD perceived a lower impact. Impacts of the pandemic were primarily described in relation to emotional distress and interference in maintaining self-care. Hampering of physical activity featured prominently, but most did not seek alternative ways to maintain activity. Despite general willingness to try novel care modalities, lack of physical interaction and communication difficulties were perceived as main barriers.

    Discussion

    Findings underline the need to alleviate emotional distress and develop adaptive strategies to empower patients to maintain wellbeing and self-care.

    Multifactorial influences underpinning a decision on COVID-19 vaccination among healthcare workers: a qualitative analysis.
    (Human vaccines & immunotherapeutics, 2022-06-10) Yoon, Sungwon; Goh, Hendra; Matchar, David; Sung, Sharon C; Lum, Elaine; Lam, Sean Shao Wei; Low, Jenny Guek Hong; Chua, Terrance; Graves, Nicholas; Ong, Marcus Eh
    COVID-19 vaccination in healthcare workers (HCW) is essential for improved patient safety and resilience of health systems. Despite growing body of literature on the perceptions of COVID vaccines in HCWs, existing studies tend to focus on reasons for 'refusing' the vaccines, using surveys almost exclusively. To gain a more nuanced understanding, we explored multifactorial influences underpinning a decision on vaccination and suggestions for decision support to improve vaccine uptake among HCWs in the early phase of vaccination rollout. Semi-structured interviews were undertaken with thirty-three HCWs in Singapore. Transcribed data was thematically analyzed. Decisions to accept vaccines were underpinned by a desire to protect patients primarily driven by a sense of professional integrity, collective responsibility to protect others, confidence in health authorities and a desire to return to a pre-pandemic way of life. However, there were prevailing concerns with respect to the vaccines, including long-term benefits, safety and efficacy, that hampered a decision. Inadequate information and social media representation of vaccination appeared to add to negative beliefs, impeding a decision to accept while low perceived susceptibility played a moderate role in the decision to delay or decline vaccination. Participants made valuable suggestions to bolster vaccination. Our findings support an approach to improving vaccine uptake in HCWs that features routine tracking and transparent updates on vaccination status, use of institutional platforms for sharing of experience, assuring contingency management plans and tailored communications to emphasize the duty of care and positive outlook associated with vaccination.

    Spillover Effects of COVID-19 on Essential Chronic Care and Ways to Foster Health System Resilience to Support Vulnerable Non-COVID Patients: A Multistakeholder Study.
    (Journal of the American Medical Directors Association, 2021-11-12) Yoon, Sungwon; Goh, Hendra; Chan, Angelique; Malhotra, Rahul; Visaria, Abhijit; Matchar, David; Lum, Elaine; Seng, Bridget; Ramakrishnan, Chandrika; Quah, Stella; Koh, Mariko S; Tiew, Pei Yee; Bee, Yong Mong; Abdullah, Hairil; Nadarajan, Gayathri Devi; Graves, Nicholas; Jafar, Tazeen; Ong, Marcus EH

    Objectives

    Little empirical research exists on how key stakeholders involved in the provision of care for chronic conditions and policy planning perceive the indirect or "spillover" effects of the COVID-19 on non-COVID patients. This study aims to explore stakeholder experiences and perspectives of the impact of COVID-19 on the provision of care for chronic conditions, evolving modalities of care, and stakeholder suggestions for improving health system resilience to prepare for future pandemics.

    Design

    Qualitative study design.

    Setting and participants

    This study was conducted during and after the COVID-19 lockdown period in Singapore. We recruited a purposive sample of 51 stakeholders involved in care of non-COVID patients and/or policy planning for chronic disease management. They included health care professionals (micro-level), hospital management officers (meso-level), and government officials (macro-level).

    Methods

    In-depth semi-structured interviews were conducted. All interviews were digitally recorded, transcribed verbatim, and thematically analyzed.

    Results

    Optimal provision of care for chronic diseases may be compromised through the following processes: lack of "direct" communication between colleagues on clinical cases resulting in rescheduling of patient visits; uncertainty in diagnostic decisions due to protocol revision and lab closure; and limited preparedness to handle non-COVID patients' emotional reactions. Although various digital innovations enhanced access to care, a digital divide exists due to uneven digital literacy and perceived data security risks, thereby hampering wider implementation. To build health system resilience, stakeholders suggested the need to integrate digital care into the information technology ecosystem, develop strategic public-private partnerships for chronic disease management, and give equal attention to the provision of holistic psychosocial and community support for vulnerable non-COVID patients.

    Conclusions and implications

    Findings highlight that strategies to deliver quality chronic care for non-COVID patients in times of public health crisis should include innovative care practices and institutional reconfiguration within the broader health system context.
