RESUMO
One of the core goals of Digital Health Technologies (DHT) is to transform healthcare services and delivery by shifting primary care from hospitals into the community. However, achieving this goal will rely on the collection, use and storage of large datasets. Some of these datasets will be linked to multiple sources, and may include highly sensitive health information that needs to be transferred across institutional and jurisdictional boundaries. The growth of DHT has outpaced the establishment of clear legal pathways to facilitate the collection, use and transfer of potentially sensitive health data. Our study aimed to address this gap with an ethical code to guide researchers developing DHT with international collaborative partners in Singapore. We generated this code using a modified Policy Delphi process designed to engage stakeholders in the deliberation of health data ethics and governance. This paper reports the outcomes of this process along with the key components of the code and identifies areas for future research.

OBJECTIVE: In Singapore, more elderly are living in nursing homes (NHs), with a resultant increase in deaths occurring in NHs. However, palliative care training is limited in Singapore's core nursing curriculum, and many NHs rely on foreign-trained staff who may not have previous palliative care training. Our study aimed to evaluate whether a needs-based course can improve the palliative care knowledge and attitudes of NH nurses in Singapore. METHODS: Twenty-five nurses participated in the study. The intervention was an 8-week palliative care course developed based on needs assessment and led by a multidisciplinary faculty. A 50-item knowledge test was administered at baseline and 0 day and 3 and 6 months postcourse. Semistructured interviews were conducted at 3 months to assess for changes in attitudes and nursing practices. RESULTS: The mean knowledge score increased significantly from 31.4 (±4.4) precourse to 35.1 (±5.1) at 3 months. Knowledge scores in end-of-life care increased up to 6 months, and scores for pain and symptom management increased significantly at 3 months. Participants reported a positive change with improved communication skills and increased compassion. There was a lack of opportunities to apply some new knowledge and skills due to regulations and perceived residents' preferences to engage more local senior staff. CONCLUSION: The multidisciplinary needs-based palliative care course using various teaching modalities with follow-up knowledge tests helped to increase knowledge and improve communication skills and attitudes of NH nurses towards palliative care. The increase in knowledge and positive change in attitudes was noted to be sustained for at least 3 months postcourse.

Precision medicine (PM) aims to revolutionise healthcare, but little is known about the role religion and spirituality might play in the ethical discourse about PM. This Perspective reports the outcomes of a knowledge exchange fora with religious authorities in Singapore about data sharing for PM. While the exchange did not identify any foundational religious objections to PM, ethical concerns were raised about the possibility for private industry to profiteer from social resources and the potential for genetic discrimination by private health insurers. According to religious authorities in Singapore, sharing PM data with private industry will require a clear public benefit and robust data governance that incorporates principles of transparency, accountability and oversight. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s41649-021-00180-4.
RESUMO
BACKGROUND: Precision medicine (PM) programs typically use broad consent. This approach requires maintenance of the social license and public trust. The ultimate success of PM programs will thus likely be contingent upon understanding public expectations about data sharing and establishing appropriate governance structures. There is a lack of data on public attitudes towards PM in Asia. METHODS: The aim of the research was to measure the priorities and preferences of Singaporeans for sharing health-related data for PM. We used adaptive choice-based conjoint analysis (ACBC) with four attributes: uses, users, data sensitivity and consent. We recruited a representative sample of n = 1000 respondents for an in-person household survey. RESULTS: Of the 1000 respondents, 52% were female and majority were in the age range of 40-59 years (40%), followed by 21-39 years (33%) and 60 years and above (27%). A total of 64% were generally willing to share de-identified health data for IRB-approved research without re-consent for each study. Government agencies and public institutions were the most trusted users of data. The importance of the four attributes on respondents' willingness to share data were: users (39.5%), uses (28.5%), data sensitivity (19.5%), consent (12.6%). Most respondents found it acceptable for government agencies and hospitals to use de-identified data for health research with broad consent. Our sample was consistent with official government data on the target population with 52% being female and majority in the age range of 40-59 years (40%), followed by 21-39 years (33%) and 60 years and above (27%). CONCLUSIONS: While a significant body of prior research focuses on preferences for consent, our conjoint analysis found consent was the least important attribute for sharing data. Our findings suggest the social license for PM data sharing in Singapore currently supports linking health and genomic data, sharing with public institutions for health research and quality improvement; but does not support sharing with private health insurers or for private commercial use.
RESUMO
OBJECTIVE: Our study examined the feasibility and validity of the EQ-5D-5L proxy questionnaire in measuring health-related quality of life (HRQoL) of nursing home residents. METHODS: Twenty-four nurses and 229 residents from 3 nursing homes in Singapore participated in this cross-sectional study. Nurses assessed residents under their care with the EQ-5D-5L proxy questionnaire. Two experienced mappers conducted Dementia Care Mapping (DCM) within 1 month in a subsample of the residents. Feasibility was evaluated according to percentage of unanswered EQ-5D-5L items and proportion of nurses who failed to respond to all items. Convergent validity was assessed by examining the correlation between EQ-5D-5L measures and DCM scores. Known-groups validity was assessed by comparing differences in EQ-5D-5L scores for residents with varying communication abilities and physical functions. RESULTS: The nurses' mean age was 35.4 years while the residents' was 73.4 years. Most residents were female (51.3%) and had the ability to communicate (81.3%). For 6 of the 229 residents (2.6%), not all items in the EQ-5D-5L were completed. The EQ-5D-5L index score correlated positively and moderately with the DCM's well/ill-being score (r = 0.433, n = 90, P < 0.01). Residents who were able to communicate effectively or had better physical function were assessed to have less severe health problems and better EQ-5D-5L scores. CONCLUSION: The EQ-5D-5L proxy questionnaire has adequate feasibility and validity when used by nurses to assess the HRQoL of nursing home residents. As it is brief and can be conveniently administered, it can be deployed on a larger scale to assess HRQoL of nursing home residents.

BACKGROUND: By 2050, 80% of the world's older population will reside in developing countries. There is a need for culturally appropriate training programs to increase awareness of eldercare issues, promote knowledge of how to better allocate resources to geriatric services, and promulgate elder-friendly policies. A monthly distance geriatric education programme between a public hospital in Singapore and health institute in Uganda was implemented. This study explored the enablers and barriers to the delivery of culturally appropriate geriatric education programmes via a videoconferencing platform. METHODS: We conducted 12 in-depth interviews with six teachers from Singapore and six learners from Uganda. The interviews were audio-recorded, transcribed and analyzed using an inductive thematic approach to analysis with the aid of the NVivo software. RESULTS: Enablers included inter-personal real-time interactions between teachers and learners whereas misaligned perceptions of cross-cultural differences between Singaporean teachers and Ugandan learners were a barrier. Rapport building, teacher motivation and institutional support were perceived to contribute to the programme's sustainability. Overall, Ugandan learners perceived that the training improved knowledge, skills, attitude and practice of geriatric care. Participants suggested that future initiatives consider aligning cross-cultural perceptions between partners, conducting a training needs analysis, exploring complementary modes of information dissemination, and allotting time for more interaction, thereby reinforcing mutual sharing. Adequate publicity and appropriate incentivisation may also better sustain the programme. CONCLUSIONS: Our findings suggest that cross-cultural training via a videoconferencing platform was feasible. Our results inform planners of future distance educational programmes of how to improve standards of cross-cultural competency and forge promising international partnerships.
RESUMO
OBJECTIVES: We examined the demographics and the clinical profile of teleconsultations conducted between an acute geriatric medicine department and 8 nursing homes over a period of 6.5 years. DESIGN: This is a prospective, descriptive study. SETTING AND PARTICIPANTS: This study was conducted in 8 nursing homes of Singapore. All nursing home patients referred to the program for teleconsultation between December 2010 and May 2017 were enrolled in the study. MEASURES: The unit observed and studied was the individual telemedicine consultation. Each unique patient contributed 1 or more observation points. The data collected included consultation dates, patient demographics, background medical comorbidities, reasons for referral, physical examination findings, primary diagnoses, and general management plans recommended by the doctors. RESULTS: There were 1673 teleconsultations conducted with 850 unique patients. Most of these patients were categorized as having moderate to severe disability. Ninety-five percent of the consultations were scheduled. The main reasons for referral were for medication review (47.6%) and behavioral problems (22.1%). The 4 commonest comorbidities were hypertension (57.0%), dementia (40.0%), diabetes (39.0%), and hyperlipidemia (38%). The most common primary diagnosis was dementia (21.6%), of which 227 of those diagnosed (62.8%) were referred for behavioral and psychological symptoms of dementia. CONCLUSIONS AND IMPLICATIONS: A telemedicine service for older patients is feasible and could be of a high quality, especially if made available in places where a high density of the latter reside, such as in the care homes and other nursing and rehabilitation facilities.

The objective of the study is to examine the 90-day readmission rate and identify the predictors for 90-day readmissions at a geriatric ward in a tertiary hospital in Singapore. A secondary analysis of case-control data was performed. Data of patients discharged from a geriatric ward between January 2015 and January 2016 were retrieved from an existing data set. Out of 564 index admissions involving older adults, the 90-day geriatric readmission rate was 10.1%. Activities of daily living dependency (odds ratio [OR]: 0.988, 95% confidence interval [CI]: [0.978, 0.999]) and living with the spouse (OR: 2.988, 95% CI: [1.388, 6.432]) were identified as significant predictors of 90-day geriatric readmissions. The study suggests that rehabilitation to restore the geriatric patient's ability to perform daily activities and adequate caregiver training for the spouse are essential in reducing geriatric readmissions. Also, postdischarge follow-up with both the patient and caregiver can greatly reduce the risk of readmission in geriatric patients.

BACKGROUND: The current screening tools for depression can be tedious to administer, especially in the elderly population with hearing impairment and/or limited proficiency in English language. OBJECTIVES: To look at the feasibility of using emoticon as a screening and assessment tool for depression in the elderly. DESIGN: Cross-sectional study. METHOD: A total of 77 elderly patients completed the study from June 2014 to August 2015 in a general geriatric outpatient clinic of an acute care hospital in Singapore. Patients rated their mood using an emoticon scale, which ranges from 1 ( most happy face) to 7 ( most sad face). Depression was assessed using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria as the gold standard. Sensitivity and specificity for depression were calculated for the cutoff scores from 1 to 7 on the emoticon scale. RESULTS: The sensitivity percentages were low across all cutoff scores. The specificity was more than 90% for the cutoff score of 5 and above on the emoticon scale. However, all the patients who had depression diagnosed using the DSM-IV criteria did not have emoticon scores of 5 and above. CONCLUSIONS: The emoticon scale was easy to use, but its effectiveness in the screening of depression in the elderly needs to be explored further. The inability to use the emoticon scale as a tool may be the lack of measurements in the other domains of the DSM-IV criteria (sleep, energy, appetite, etc.), rather than failure of the emoticon scale to assess mood.

This was an in-depth qualitative study that looked at the reasons patients were referred to the Clinical Ethics Committee (CEC) of an acute hospital in Singapore and explore how the CEC approached cases referred. Jonsen's four topics approach was applied in the deliberative process for all cases. A comprehensive review of the case records of 28 patients referred consecutively to the CEC from 1 January 2012 to 31 December 2014 was conducted. Data and information was collated from the referral forms, patient medical records, and emails communicated among CEC members. A deductive approach to thematic analysis based on Jonsen's four topics approach was used to analyze the documents. Majority of the patients were male (94%), Chinese (76%), and above 65 years of age (41%). Ethical dilemmas surfaced due to differences in opinion regarding withholding of aggressive management (53%), withdrawing treatment (35%), and ascertaining patient's autonomy (12%). In most cases, the patients' preference on end-of-life care was unknown (82%). The main reasons for referral to the CEC were conflicts in clinical management and uncertainty about the decision-making capacity of patients. The CEC members tended to emphasize on "patient preference" more than the other quadrants in the four topics approach as they worked through each case. The Jonsen's four topics approach lays the groundwork to frame ethical dilemmas that can be easily applied in the clinical setting and is a useful tool for the CEC's teaching and discussion. Nonetheless, the approach only organizes ethical dilemmas and requires clinicians to apply own judgment in weighing ethical principles. Further studies can look into adapting the four topics approach to suit the local practices and context.
RESUMO
Photodynamic therapy (PDT) of cancer involves the use of a photosensitizer that can be light-activated to eradicate tumors via direct cytotoxicity, damage to tumor vasculature and stimulating the body's immune system. Treatment outcome may vary between individuals even under the same regime; therefore a non-invasive tumor response monitoring system will be useful for personalization of the treatment protocol. We present the combined use of diffuse optical spectroscopy (DOS) and diffuse correlation spectroscopy (DCS) to provide early assessment of tumor response. The relative tissue oxygen saturation (rStO2) and relative blood flow (rBF) in tumors were measured using DOS and DCS respectively before and after PDT with reference to baseline values in a mouse model. In complete responders, PDT-induced decreases in both rStO2 and rBF levels were observed at 3 h post-PDT and the rBF remained low until 48 h post-PDT. Recovery of these parameters to baseline values was observed around 2 weeks after PDT. In partial responders, the rStO2 and rBF levels also decreased at 3 h post PDT, however the rBF values returned toward baseline values earlier at 24 h post-PDT. In contrast, the rStO2 and rBF readings in control tumors showed fluctuations above the baseline values within the first 48 h. Therefore tumor response can be predicted at 3 to 48 h post-PDT. Recovery or sustained decreases in the rBF at 48 h post-PDT corresponded to long-term tumor control. Diffuse optical measurements can thus facilitate early assessment of tumor response. This approach can enable physicians to personalize PDT treatment regimens for best outcomes.

There has been a growing trend in addressing spiritual needs in caring for the person, especially nearing the end of one's life. Advance care planning (ACP) facilitates understanding of preferences and explores the spiritual and existential aspects of care. This study explores the views and preferences of a group of Catholic nuns in Singapore, specifically looking at what was meaningful and valuable to them when determining treatment options at the end of life. Twenty-three nuns were purposively recruited in July 2012. A focus group discussion was conducted after administration of a questionnaire and attendance at a 1-hour talk on ACP. Slightly more than half had heard of ACP prior to the talk. The majority agreed that ACP was not against their religious beliefs" and that quality of life was important to them. The themes that emerged from this study were autonomy and freedom, spirituality and quality of life, and the meaning of ACP. The findings of this study suggested that spirituality and faith define the way the participants lived their lives, including their views and preferences on end-of-life care. Integrating spirituality into an essential domain of care will help the spiritual community honor a crucial part of end-of-life discussions and afford a greater discernment of the deep meaning that ACP holds.

INTRODUCTION: Prolonged stay in acute hospitals increases the risk of hospital-acquired infections in older patients, and disrupts patient flow and access to care due to bed shortages. We aimed to investigate the factors associated with prolonged length of stay (pLOS) among older patients (aged ≥ 78 years) in a tertiary hospital, to identify the potentially modifiable risk factors that could direct interventions to reduce length of stay (LOS). METHODS: During a three-month period from January 2013 to March 2013, we identified 72 patients with pLOS (LOS ≥ 21 days) and compared their demographic and clinical variables with that of 281 randomly selected control patients (LOS < 21 days) using univariate and multivariate logistic regression analyses. RESULTS: The mean age of the patients was 85.30 ± 5.34 years; 54% of them were female and 72% were of Chinese ethnicity. Logistic regression revealed the following significant factors for increased LOS: discharge to intermediate and long-term care services (odds ratio [OR] 9.22, 95% confidence interval [CI] 3.56-23.89; p < 0.001); increased severity of illness (OR 2.41, 95% CI 1.12-5.21; p = 0.025); and presence of caregiver stress (OR 3.85, 95% CI 1.67-8.91; p = 0.002). CONCLUSION: Presence of caregiver stress and nursing home placement are potential modifiable risk factors of pLOS among older patients. Early identification and management of caregiver stress, as well as expediting discharge planning, may help to reduce the length of stay for this cohort.

Tumor response during photodynamic therapy (PDT) is heavily dependent on treatment parameters such as light dose, photosensitizer concentration, and tissue oxygenation. Therefore, it is desirable to have a real-time hemodynamic monitoring device in order to fine-tune the parameters and improve PDT efficacy. In this paper, such a tumor response monitoring system was built incorporating both frequency domain diffuse optical spectroscopy (FD-DOS) and diffuse correlation spectroscopy (DCS), which enables concurrent monitoring of tissue oxygenation (StO2), total hemoglobin concentration (THC) and relative blood flow (rBF). The tumor metabolic rate of oxygen (TMRO2) was calculated by using the hemodynamic parameters. Mouse models bearing xenograft tumors were subjected to chlorin e6 (Ce6)-mediated PDT, and the four parameters were monitored with varying treatment conditions. The results show (1) At 3 h post-PDT, rStO2, rBF and rTMRO2 exhibited sharp PDT-induced decreases in responders (>40% reduction in tumor volume). Statistically significant difference between responders and non-responders were observed in rStO2 and rBF, but not in rTMRO2. (2) Non-responders show gradual recovery of rStO2, rBF and rTMRO2 from â¼24 h post-PDT, while responder group did not show recovery up until 48 h post-PDT. Long-term study results up to 2 weeks are also shown. It suggests the hybrid diffuse optical system is not only capable of real-time treatment monitoring, but also able to extract tumor metabolic rate of oxygen to provide more insights about therapy mechanism. Translation of this technique to the clinic will make a quick prognosis feasible and help with treatment optimization.
