Stroke Rehabilitation Use and Caregiver Psychosocial Health Profiles in Singapore: A Latent Profile Transition Analysis

OBJECTIVES

To identify and describe caregiver profiles based on their psychosocial health characteristics over a 12-month period and transitions among these profiles, to determine if stroke rehabilitation use at 12 months post-stroke differed by caregiver profile transition patterns, and to investigate if caregiver profiles at 3 months post-stroke moderate the association of stroke rehabilitation use at 3 months and 12 months post-stroke after accounting for covariates.

DESIGN

Latent profile transition analysis of caregiver psychosocial health with stroke rehabilitation use at 12 month post-stroke as outcome.

SETTING AND PARTICIPANTS

A total of 149 stroke patient-caregiver dyads from the Singapore Stroke Study.

METHODS

Cross-sectional latent profile analyses were conducted on caregiver psychosocial health indicators of burden, depression, health status, quality of relationship with patient, and social support. Changes in latent profile classification over 3 time points (baseline, 3 months, and 12 months post-stroke) were analyzed using latent transition analysis. A transition model with stroke rehabilitation use at 12 months post-stroke as the outcome was tested after accounting for covariates.

RESULTS

Two distinct caregiver psychosocial health latent profiles were found across time: nondistressed and distressed. Most caregivers were classified as nondistressed and remained nondistressed over time. Distressed caregivers at baseline were 76% likely to become nondistressed at 12 month post-stroke. Regardless of profile transition patterns, nondistressed caregivers at 12 months post-stroke tended to have cared for stroke rehabilitation nonusers at 12 months post-stroke. Patient depression explained profile classification at 3 months and 12 months post-stroke. After accounting for covariates, rehabilitation users at 3 months post-stroke tended to continue using rehabilitation at 12 months post-stroke only when they had nondistressed caregivers at 3 months post-stroke.

CONCLUSIONS AND IMPLICATIONS

Whether caregiver adaptation explains the associations between the latent profile transition patterns and rehabilitation use at 12 months post-stroke should be examined. Early psychosocial health assessment and sustained support should be made available to stroke caregivers to enhance their well-being and subsequent patient rehabilitation participation.

Promoting BioPsychoSocial health of older adults using a Community for Successful Ageing program (ComSA) in Singapore: A mixed-methods evaluation

BioPsychoSocial health promotion is increasingly emphasized for Successful Ageing. Few programs are known to target BioPsychoSocial health of older adults and their community. The Community for Successful Ageing: Community Development program (ComSA CD) was developed in Singapore for this purpose. This study assessed program effects on BioPsychoSocial health and civic engagement behaviours of participants. ComSA CD offered self-care healthy lifestyle education (Bio-physical), guided autobiography (Psychological) and a civic engagement component which galvanized participants to solve community issues (Social). Recruitment occurred through self-care or guided autobiography; following which participants were funnelled into the civic engagement component. A mixed-methods quasi-experimental evaluation was conducted, using a pre-post one-year survey (N=232) with those exposed and unexposed (rejected) to ComSA CD. Using a generalized linear model, associations between post one-year BioPsychoSocial outcomes and exposure group were quantified using percentage change, adjusting for baseline outcome and group differences. Concurrently, program effects were explored through six focus groups with program implementers and participants using thematic analysis. The program had multiple positive effects. Participants recruited via self-care also taking part in civic engagement reported 31% higher frequency of self-care (95% CI=21% to 68%) post one-year compared to unexposed participants. Qualitative findings illustrated how the civic engagement component stimulated agency of participants to push for neighborhood changes and civic engagement initiatives. The quantitative survey highlighted that this effect was strongest among those funnelled from guided-autobiography (92% higher frequency of civic engagement at post one-year than unexposed; 95%CI=41% to 178%) compared to those funnelled from self-care (53% higher than unexposed, 95%CI=17% to 114%). It was found qualitatively that guided-autobiography enabled more meaningful bonding and communication than the self-care component, explaining quantitative effects on social support only present among guided autobiography participants (36% higher than unexposed; 95%CI=11% to 68%). Findings highlighted the importance of improving group dynamics for collective action.

Community involvement in the development and implementation of chronic condition programmes across the continuum of care in high- and upper-middle income countries: A systematic review

BACKGROUND

Community involvement is an important component of health programme development and implementation, including those focused on chronic condition treatment and management. Yet, few studies explore the manifestations of community involvement in chronic care programmes. Our review aims to examine the evidence on how communities are involved in planning and implementing chronic condition programmes in high and upper-middle income countries.

METHODS

Eligible studies included those that involved the community in the planning, implementation, monitoring and evaluation of health services, policy or health interventions. We searched Medline, Embase, Global Health, Scopus, and LILACs from 2000 to 2016, independently screened articles for inclusion, conducted data extraction, and assessed studies for risk of bias.

RESULTS

27,232 records were identified and after screening, 32 met inclusion criteria. We conducted a narrative synthesis to report on the forms and processes of community involvement used across mental health programmes and contrast this with the paucity of evidence on comparable programmes addressing other chronic conditions. Challenges reported included user factors, organisational factors, and social challenges such as stigma.

CONCLUSION

Our review adds to the evidence supporting community involvement in chronic condition management and the processes that contribute to successful and sustainable involvement. We report on a model, derived from inductive analysis, that considers social and cultural components, organisational factors and stakeholder relationships as underpinning the development of community interventions across the care continuum.

Financial difficulties are associated with greater total pain and suffering among patients with advanced cancer: results from the COMPASS study

BACKGROUND

The Universal Health Coverage goals call for access to affordable palliative care to reduce inequities in "total pain" and suffering. To achieve this, a patient-centred understanding of these inequities is required.

AIM

To assess association of total pain and suffering (i.e. physical, psychological, social, and spiritual health outcomes) and perceived health care quality with financial difficulties among stage IV solid malignancy patients.

DESIGN

Using baseline data from the COMPASS cohort study, we assessed total pain and suffering including physical (physical and functional well-being, pain, symptom burden), psychological (anxiety, depression, emotional well-being), social (social well-being), and spiritual (spiritual well-being, hope) outcomes and perceived health care quality (physician communication, nursing care, and coordination/responsiveness). Financial difficulties were scored by assessing patient perception of the extent to which their resources were meeting expenses for their treatments, daily living, and other obligations. We used multivariable linear/logistic regression to test association between financial difficulties and each patient-reported outcome.

SETTING/PARTICIPANTS

Six hundred stage IV solid malignancy patients in Singapore.

RESULTS

Thirty-five percent reported difficulty in meeting expenses. A higher financial difficulties score was associated with worse physical, psychological, social, spiritual outcomes, and lower perceived quality of health care coordination and responsiveness (i.e. greater total pain and suffering) (all p < 0.05). These associations persisted after adjustment for socio-economic indicators.

CONCLUSION

Results identify advanced cancer patients with financial difficulties to be a vulnerable group with greater reported total pain and suffering. A holistic patient-centred approach to care at end-of-life may help meet goals for Universal Health Coverage.

Short-term strength and balance training does not improve quality of life but improves functional status in individuals with diabetic peripheral neuropathy: a randomised controlled trial

AIMS/HYPOTHESIS

The aim of this study was to test the effectiveness of a structured strength and balance training intervention in improving health-related quality of life (HRQoL) and functional status in individuals with diabetic peripheral neuropathy (DPN).

METHODS

The study was a single-blind parallel-group randomised controlled trial comparing 2 months of once-weekly home-based strength and balance training against standard medical therapy. Participants were patients with physician-diagnosed type 2 diabetes and neuropathy recruited from five public sector institutions in Singapore between July 2014 and October 2017. Participants were block-randomised to intervention or control arms. Outcomes were assessed at baseline, 2 months and 6 months by a trained assessor blinded to group assignment. Primary outcomes were change in physical component summary (PCS) score of SF-36v2 (a 36-item generic HRQoL instrument that has been validated for use in Singapore) and EQ-5D-5L index score (derived from a five-item generic HRQoL instrument [EQ-5D-5L]) over 6 months. Secondary outcomes were change in functional status (timed up-and-go [TUG], five times sit-to-stand [FTSTS], functional reach, static balance, ankle muscle strength and knee range of motion) and balance confidence over 6 months. Mean differences in scores between groups were compared using mixed models.

RESULTS

Of the 143 participants randomised (intervention, n = 70; control, n = 73), 67 participants were included in each arm for the final intention-to-treat analysis. The two groups were similar, except in terms of sex. There were no significant differences between groups on the primary outcomes of PCS score (mean difference [MD] 1.56 [95% CI -1.75, 4.87]; p = 0.355) and EQ-5D-5L index score (MD 0.02 [95% CI -0.01, 0.06]; p = 0.175). There were significant improvements in TUG test performance (MD -1.14 [95% CI -2.18, -0.1] s; p = 0.032), FTSTS test performance (MD -1.31 [95% CI -2.12, -0.51] s; p = 0.001), ankle muscle strength (MD 4.18 [95% CI 0.4, 7.92] N; p = 0.031), knee range of motion (MD 6.82 [95% CI 2.87, 10.78]°; p = 0.001) and balance confidence score (MD 6.17 [95% CI 1.89, 10.44]; p = 0.005). No adverse events due to study participation or study intervention were reported.

CONCLUSIONS/INTERPRETATION

Short-term structured strength and balance training did not influence HRQoL but produced sustained improvements in functional status and balance confidence at 6 months. More intensive interventions may be needed to influence HRQoL in these individuals. However, this intervention may be a useful treatment option for individuals with DPN to reduce the risk of falls and injuries.

Dyadic approach to post-stroke hospitalizations: role of caregiver and patient characteristics

Aim

To study the association of caregiver factors and stroke patient factors with rehospitalizations over the first 3 months and subsequent 3–12 months post-stroke in Singapore.

Methods

Patients with stroke and their caregivers were recruited in the Singapore Stroke Study, a prospective yearlong cohort. While caregiver and patient variables were taken from this study, hospitalization data were extracted from the national claims database. We used Poisson modelling to perform bivariate and multivariable analysis with counts of hospitalization as the outcome.

Results

Two hundred and fifty-six patient with stroke and caregiver dyads (N = 512) were analysed, with patients having spouse (60%), child (29%), sibling (4%) and other (7%) as their caregivers. Among all participants, 89% of index strokes were ischemic, 57% were mild in severity and more than half (59%) of the patients had moderate or severe disability post-stroke as measured on the Modified Rankin Scale. Having social support in the form of a foreign domestic worker for general help of caregiver reduced the hospitalization rate over 3 months post-stroke by 66% (IRR: 0.342; 95% CI: 0.180, 0.651). Compared to having a spousal caregiver, those with a child caregiver had an almost three times greater rate of hospitalizations over 3–12 months post-stroke (IRR: 2.896; 95% CI: 1.399, 5.992). Higher reported caregiving burden at the 3-month point was associated with the higher subsequent rate of hospitalization.

Conclusion

Recommendations include the adoption of a dyadic or holistic approach to post-stroke care provision by healthcare practitioners, giving due importance to both patients with stroke and their caregivers, integrating caregivers in the healthcare system to extend the care continuum to include informal care in the community and provision of timely support for caregivers.

Patients with more comorbidities have better detection but poorer management of chronic diseases

Background

The burden of non-communicable diseases (NCDs) is rising rapidly in middle-income countries (MICs), where NCDs are often undiagnosed, untreated and uncontrolled. How comorbidity impacts diagnosis, treatment, and control of NCDs is an emerging area of research inquiry and have significant clinical implications as highlighted in the recent National Institute for Care Excellence (NICE) guidelines for treating patients suffering from multiple NCDs. This is the first study to examine the association between increasing numbers of comorbidities with being undiagnosed, intreated, and uncontrolled for NCDs, in six large MICs.

Methods

Cross-sectional analysis of WHO SAGE Wave 1 (2007-10), which consisted of adults aged ≥18 years from six populous MICs including, China, Ghana, India, Mexico, Russia and South Africa (overall n = 41, 557).

Results

Higher number of comorbidities was associated with better detection of hypertension, angina and arthritis, and better odds of having treatment for hypertension and angina. However, increasing comorbidity had the opposite effect on being uncontrolled, and was associated with increased odds of uncontrolled hypertension, angina, arthritis, and asthma. Comorbidity with concordant conditions was associated with improved diagnosis and treatment of hypertension and angina. Comorbidity with concordant conditions was not associated with decreased nor increased odds of being uncontrolled for all NCDs.

Conclusions

Patients with more comorbidities have better diagnosis of chronic conditions, but this does not translate into better management and control of these conditions. Improving continuity of care and monitoring treatment are priorities for health systems with ageing populations.

Key messages

Patients with more comorbidities have better diagnosis of chronic conditions. but this does not translate into better management and control of these conditions.

Exploring the implementation of the Community for Successful Ageing (ComSA)program in Singapore: lessons learnt on program delivery for improving BioPsychoSocial health

BACKGROUND

The Community for Successful Ageing (ComSA) program has implemented overlapping BioPsychoSocial (BPS) components as part of a Community Development (CD) grassroots and volunteer-led initiative. Implementation of such multi-component programming is influenced by known program characteristics including novelty, complexity and observability as well as related organizational factors. As such, we explored ComSA CD's implementation from the organizational perspective, seeking to inform program improvements.

METHODS

We conducted four focus groups with program staff, partners and trainers (total N = 21 participants). Findings were analysed using an interpretative approach and synthesized into a line of argument informing lessons learnt.

RESULTS

An implementation framework was identified. It is guided by considering the influence of known program characteristics across major themes, representing three core implementation stages. These and supporting sub-themes are elaborated in turn: 1) Creating commitment toward the program was challenged by novelty and at times a lack of shared understanding of ComSA CD, particularly relating to the S component. Overall, cohesion within organizational contexts and having a strong rapport with the community (ability to engage) were needed to persuade volunteers and participants to commit to the program. 2) Coordination and resource allocation were influenced by the complexity of interconnecting BPS components - requiring aligning communication between partners and adapting the BPS sequence, given the separated management structure of program trainers. Efficiency of resource utilization was constrained by the ability to pool and match resources given the limited manpower and community partners who worked-in-silo due to a KPI-centric culture. 3) Collaborative program monitoring and appraisal increased observability of the program's benefits, but depended on partners' prior commitment. Despite appreciating its holistic BPS programming, dropout rate was used as a way to gauge program success, which has limited interpretability. Occasional uncertainty about the program value contributed to concerns about duplicating existing ageing programs, particularly those related to the B component.

CONCLUSION

Lessons learnt for improving BPS programming include (1) eliciting better participants' buy-in and shared program vision, (2) increasing adaptability of BPS sequence and building a culture of shared values for working together (3) and developing comprehensive monitoring systems for program appraisal.

Theory and Design of the Community for successful ageing (ComSA) program in Singapore: connecting BioPsychoSocial health and quality of life experiences of older adults

BACKGROUND

Despite the emphasis on holistic health promotion in community programs for older people, few studies explicitly consider how BioPsychoSocial (BPS) health elements are interconnected and function to improve Quality of Life (QoL). The Community for Successful Ageing (ComSA) program in Singapore focuses on Community Development (CD) initiatives for older people, accounting for BPS theory in its design and content. Biological (B) health is conceived as physiological and cognitive functioning and related biological self-care; Psychological (P) health as feelings of life satisfaction, and Social health (S) as perceived social support and civic engagement. Furthermore, three overlapping sub-constructs are theorized to connect these elements. Namely Bio-Psychological (BP) health in terms of self-perceptions of ageing; the Psycho-Social (PS) aspects of interpersonal communication; and the Socio-Communal (SC) health in terms of civic engagement. BPS health is conceived as distinct from QoL, defined as composed of control, autonomy, self-realisation and pleasure (measured by CASP-19) of the older person. We examined 1) interconnections of BPS constructs and related sub-constructs and 2) their associations with QoL to inform a practical, applied program theory.

METHODS

A baseline survey (n = 321) of program participants (Mean = 70 years, SD = 8.73). All continuous variables were binarized as 'high' if the scores were above the median. Multivariate logistic regression was used to assess 1) the adjusted effect of each BPS construct on CASP-19, and 2) the odds of scoring high on one BPS construct with the odds of scoring high on a related sub-construct (e.g. B and BP health).

RESULTS

The strongest relationship with QoL was markedly with BP self-perceptions of ageing (OR = 4.07, 95%CI = 2.21-7.49), followed by P life satisfaction (OR = 3.66, 95%CI = 2.04-6.57), PS interpersonal communication (OR = 2.42, 95%CI = 1.23-4.77), SC civic engagement (OR = 1.94, 95%CI = 1.05-3.57), and S social support (OR = 1.89, 95%CI = 1.06-3.38). Core B, P and S health were closely associated with their sub-constructs.

CONCLUSION

ComSA CD is tightly coupled to its proposed program theory. It offers classes to improve B self-care and BP self-perceptions of ageing, group-based guided autobiography to improve P life-satisfaction and PS interpersonal communication, and community initiatives that encourage seniors to solve community issues. This holistic approach is likely to enhance ageing experiences and QoL.

Evaluation of Constructing Care Collaboration - nurturing empathy and peer-to-peer learning in medical students who participate in voluntary structured service learning programmes for migrant workers

BACKGROUND

Experiential learning through service provides opportunities to nurture and practice empathy. Of growing concern, studies showed significantly decreased empathy scores as students progress through medical school. Additionally, peer-to-peer learning provides an effective way for students to learn. Constructing Care Collaboration (CCC) is a student initiated, structured-service-learning-program that promotes the development of empathy and peer-to-peer teaching. CCC is conducted in cycles of 6 sessions. This is a mixed methods study that explores the effectiveness of CCC as a service learning platform in developing student participants' empathy, social and cultural competencies, communication skills and peer-to-peer teaching skills, ultimately aiming to promote a culture of serving the underprivileged.

METHODS

The study comprised of a self-administered quantitative questionnaire and qualitative interviews. Both evaluated if CCC participation developed volunteers' social-awareness, cultural competency, communication, confidence and motivation to teach their peers.

RESULTS

Quantitative data were collated from 38 completed student volunteers' questionnaires. Volunteers generally agreed CCC improved social-awareness and cultural competency. It increased confidence of participants in approaching migrant-workers, communicating with people from different social backgrounds, and promoted a culture of peer-to-peer teaching. Thematic analysis of 17 interviews was conducted. Themes identified include: increased empathy towards migrant-workers, improved communication skills, and identifying benefits and challenges in peer-to-peer teaching.

CONCLUSION

From the quantitative and qualitative information gathered, CCC has been shown to be effective in nurturing participants' self-reported empathy, cultural competence, communication skills and improved attitude towards peer-to-peer teaching. Given its effectiveness, CCC can be adopted as a model for structured service-learning.

Community participation in health services development, implementation, and evaluation: A systematic review of empowerment, health, community, and process outcomes

Background

Community participation is widely believed to be beneficial to the development, implementation and evaluation of health services. However, many challenges to successful and sustainable community involvement remain. Importantly, there is little evidence on the effect of community participation in terms of outcomes at both the community and individual level. Our systematic review seeks to examine the evidence on outcomes of community participation in high and upper-middle income countries.

Methods and findings

This review was developed according to PRISMA guidelines. Eligible studies included those that involved the community, service users, consumers, households, patients, public and their representatives in the development, implementation, and evaluation of health services, policy or interventions. We searched the following databases from January 2000 to September 2016: Medline, Embase, Global Health, Scopus, and LILACs. We independently screened articles for inclusion, conducted data extraction, and assessed studies for risk of bias. No language restrictions were made. 27,232 records were identified, with 23,468 after removal of duplicates. Following titles and abstracts screening, 49 met the inclusion criteria for this review. A narrative synthesis of the findings was conducted. Outcomes were categorised as process outcomes, community outcomes, health outcomes, empowerment and stakeholder perspectives. Our review reports a breadth of evidence that community involvement has a positive impact on health, particularly when substantiated by strong organisational and community processes. This is in line with the notion that participatory approaches and positive outcomes including community empowerment and health improvements do not occur in a linear progression, but instead consists of complex processes influenced by an array of social and cultural factors.

Conclusion

This review adds to the evidence base supporting the effectiveness of community participation in yielding positive outcomes at the organizational, community and individual level.

Mapping the Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory to the Health Utility Index Mark III

PURPOSE

To map the Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory (ADCS-ADL) to the Health Utility Index Mark III (HUI3) in people living with dementia (PWD) and to compare the performance of five methods for mapping.

METHODS

A cross-sectional study of 346 dyads of community-dwelling PWD and family caregiver was carried out in Singapore. ADCS-ADL and HUI3 were rated by the family caregivers. Disease severity ratings and Mini Mental State Examination (MMSE) results were retrieved from medical records. A recently proposed mapping method called the Mean Rank Method (MRM) was described and applied, and the results were compared with regression-based mapping, including ordinary least squares, censored least absolute deviation (CLAD), Tobit and response mapping.

RESULTS

The MRM produced a mapped utility distribution that closely resembled the observed utility distribution. The standard deviations (SDs) of the observed and MRM-mapped utility were both 0.340, whereas the SDs of the other mapped utilities ranged from 0.243 (response mapping) to 0.283 (CLAD). Regressing the MRM- and CLAD-mapped and observed utility values upon disease severity and MMSE gave similar regression lines (each P > 0.05). Regressing the other mapped utility values upon the covariates under- (over-) estimated the utility of good (poor) clinical states. However, regression-based mapping methods gave a better fit at the individual level, as measured by root mean square error, mean absolute error and R². K fold cross-validation gave similar results.

CONCLUSIONS

The MRM is accurate at the group level. The regression-based mapping methods are more accurate for making individual-level prediction. In addition, CLAD also performed reasonably well at the group level.

Acceptance of Tele-Rehabilitation by Stroke Patients: Perceived Barriers and Facilitators

OBJECTIVE

To explore the perceived barriers and facilitators of tele-rehabilitation (TR) by stroke patients, caregivers and rehabilitation therapists in an Asian setting.

DESIGN

Qualitative study involving semi-structured in-depth interviews and focus group discussions.

SETTING

General community.

PARTICIPANTS

Participants (N=37) including stroke patients, their caregivers, and tele-therapists selected by purposive sampling.

INTERVENTIONS

Singapore Tele-technology Aided Rehabilitation in Stroke trial.

MAIN OUTCOME MEASURES

Perceived barriers and facilitators for TR uptake, as reported by patients, their caregivers, and tele-therapists.

RESULTS

Thematic analysis was used to inductively identify the following themes: facilitators identified by patients were affordability and accessibility; by tele-therapists, was filling a service gap and common to both was unexpected benefits such as detection of uncontrolled hypertension. Barriers identified by patients were equipment setup-related difficulties and limited scope of exercises; barriers identified by tele-therapists were patient assessments, interface problems and limited scope of exercises; and common to both were connectivity barriers. Patient characteristics like age, stroke severity, caregiver support, and cultural influence modified patient perceptions and choice of rehabilitation.

CONCLUSIONS

Patient attributes and context are significant determinants in adoption and compliance of stroke patients to technology driven interventions like TR. Policy recommendations from our work are inclusion of introductory videos in TR programs, provision of technical support to older patients, longer FaceTime sessions as re-enforcement for severely disabled stroke patients, and training of tele-therapists in assessment methods suitable for virtual platforms.

Inclination towards research and the pursuit of a research career among medical students: an international cohort study

BACKGROUND

Involvement of clinicians in biomedical research is imperative for the future of healthcare. Several factors influence clinicians' inclination towards research: the medical school experience, exposure to research article reading and writing, and knowledge of research. This cohort study follows up medical students at time of graduation to explore changes in their inclination towards research and pursuing a research career compared to their inclination at time of entry into medical school.

METHODS

Students from medical schools in six different countries were enrolled in their first year of school and followed-up upon graduation in their final year. Students answered the same self-administered questionnaire at both time points. Changes in inclination towards research and pursuing a research career were assessed. Factors correlated with these changes were analysed.

RESULTS

Of the 777 medical students who responded to the study questionnaire at entry into medical school, 332 (42.7%) completed the follow-up survey. Among these 332 students, there was no significant increase in inclination towards research or pursuing a research career over the course of their medical schooling. Students from a United States based school, in contrast to those from schools other countries, were more likely to report having research role models to guide them (51.5% vs. 0%-26.4%) and to have published in a peer-reviewed journal (75.7% vs. 8.9%-45%). Absence of a role model was significantly associated with a decrease in inclination towards research, while an increased desire to learn more about statistics was significantly associated with an increase in inclination towards pursuing a research career.

CONCLUSION

Most medical students did not experience changes in their inclination towards research or pursuing a research career over the course of their medical schooling. Factors that increased their inclination to undertaking research or pursuing a research career were availability of a good role model, and a good knowledge of both the research process and the analytical tools required.

Functional status mediates the association between peripheral neuropathy and health-related quality of life in individuals with diabetes

AIMS

To examine differences in health-related quality of life (HRQoL) between patients with and without diabetic peripheral neuropathy (DPN), and whether these differences can be explained by functional deficits.

METHODS

This was a cross-sectional study of 160 patients with type 2 diabetes mellitus, 80 with DPN and 80 without. Assessments included HRQoL (health utility score derived from EQ-5D-5L), functional status measurements [muscle strength, timed up and go (TUG), five times sit-to-stand (FTSTS), functional reach, body sway velocity] and self-reported balance confidence [Activities-specific Balance Confidence (ABC) scale].

RESULTS

Mean utility scores were 0.67 ± 0.14 and 0.77 ± 0.16 in patients with and without DPN, respectively (p < 0.001). Patients with DPN had lower great toe extensor strength (6.4 ± 1.8 vs 7.6 ± 2.8 lbs, p = 0.001), greater body sway velocity (2.40 ± 1.31 vs 1.90 ± 0.52 mm/s, p = 0.002), slower TUG (12.1 ± 4.6 vs 10.1 ± 2.3 s, p < 0.001) and FTSTS (15.8 ± 5.8 vs 13.9 ± 5.4 s, p = 0.03) scores, and lower ABC score (73.4 ± 21.3 vs 82.6 ± 16.9, p = 0.003), compared to those without DPN. On stepwise multiple regression, DPN status, FTSTS, body sway velocity, BMI, diabetes duration, pain, and gender explained 38% of HRQoL variance. Addition of ABC score into the model explained 45% of variance. Results from structural equation modelling showed that DPN had direct effects on HRQoL and indirect effects through FTSTS, body sway velocity, and ABC score, with χ ² = 8.075 (p = 0.044), root mean square error of approximation = 0.103 (lower bound 0.015, upper bound 0.191), Comparative Fit Index = 0.966, Tucker-Lewis Index = 0.887, and Standardized Root Mean Square Residual = 0.053.

CONCLUSIONS

Patients with DPN have worse HRQoL compared to patients without DPN, partly mediated by functional status parameters. Effective interventions targeting functional status may be beneficial in improving HRQoL in these patients.

Preliminary evidence that acute stress moderates basal testosterone's association with retaliatory behavior

A contribution to a special issue on Hormones and Human Competition. Testosterone is theorized to increase retaliation after social provocation. However, empirical evidence in support of these theories is mixed. The present research investigated whether acute stress causally suppresses testosterone's association with retaliation. We also explored sex differences in behavioral responses to acute stress. Thirty-nine participants (51.28% male) were randomly assigned to a high- or low-stress condition. Then participants engaged in 20 one-shot rounds of the ultimatum game, which was used to assess retaliatory behavioral responses to unfair treatment. Participants provided two saliva samples to measure testosterone and cortisol concentrations - one sample before the stress manipulation, and the second after the ultimatum game (20minutes post-stressor). Results revealed a positive association between basal testosterone and retaliation in the low-stress condition, but not in the high-stress condition. Further, cortisol concentrations increased in the high- compared to the low-stress condition, and these cortisol changes moderated the association between basal testosterone and retaliation. The associations between basal testosterone and retaliation under varying levels of stress were similar in men and women. However, there was a sex difference in behavioral responses to the stress manipulation that was independent of testosterone. In women, the high-stress condition reduced retaliation compared to the low-stress condition, whereas in men the opposite pattern emerged. Collectively, this study (i) provides preliminary evidence that experimentally manipulated stress blocks basal testosterone's association with retaliation, and (ii) reveals a sex difference in retaliation under varying levels of stress. Discussion focuses on mechanisms, limitations, and the need for follow-up studies with larger sample sizes.

Validation of the Stroke and Aphasia Quality of Life Scale in a multicultural population

PURPOSE

This study aimed to determine the reliability and validity of the Stroke and Aphasia Quality of Life Scale (SAQOL-39 g) and its Mandarin adaptation SAQOL-CSg in Singaporean stroke patients.

METHOD

First-time stroke survivors were recruited at three months post-stroke and underwent a series of questionnaires in their dominant language (English/Mandarin). This included: SAQOL-39 g/CSg, National University Hospital System (NUHS) Aphasia Screening Test, Barthel Index, Modified Rankin Scale, Mini Mental State Examination, Frontal Assessment Battery, Center for Epidemiologic Studies Depression Scale and the Eurol-Qol Health Questionnaire (EQ-5D). The SAQOL-39 g/SAQOL-CSg was repeated within 1 week (± 6 days).

RESULTS

Ninety-four participants (96.9%) were able to self-report and their results presented here. Both the SAQOL-39 g/SAQOL-CSg showed good internal consistency (α = 0.96/0.97), test-retest reliability (ICC= 0.99/0.98), convergent (rs  =0.64-0.81 and 0.66-0.88, respectively) and discriminant (rs = 0.35-0.53 and 0.48-0.62, respectively) validity. The correlation between the SAQOL-39 g and the EQ-5D Visual Analogue Scale was 0.27. Further inspection of the EQ-5DVAS scores revealed correlations in different directions for Malay versus Chinese participants.

CONCLUSIONS

Both the SAQOL-39 g and SAQOL-CSg demonstrated good reliability and validity. Our results suggested some influence of ethnicity in self-rating of health status in relation to SAQOL-39 g scores. Further research is warranted to examine its use with stroke survivors with greater stroke severity and over time. Implications for Rehabilitation Validation of SAQOL in Singapore: Both the SAQOL-39g and the SAQOL-CSg may be used to measure the HRQoL of stroke survivors with and without aphasia in Singapore. Further investigation is required to examine use with stroke survivors with greater stroke severity and over time.

Effect of a new longitudinal interprofessional geriatric medicine educational track on knowledge and attitude of medical students: a controlled cohort study

A new interprofessional geriatric medicine curriculum was recently introduced at a large undergraduate Asian medical school. A longitudinal controlled interventional cohort study was conducted to evaluate the effect of the new curriculum on the knowledge and attitudes of medical students. The medical students under the new curriculum formed the intervention cohort, and those under the former curriculum formed the control cohort. To test knowledge, the University of California at Los Angeles (UCLA) geriatrics knowledge test (GKT) was used in Year 2 and the University of Michigan GKT in Year 5. Geriatrics attitudes were evaluated using the UCLA geriatrics attitudes test in Years 2 and 5. Not surprisingly, geriatrics knowledge at the end of Year 5 of medical school was enhanced to a greater degree in the intervention cohort than the control cohort, although improvements in geriatrics attitudes in each cohort were of similar magnitude by the end of Year 5, suggesting that factors other than a formal geriatrics curriculum influenced the improvements in geriatrics attitudes. This article is one of few published on the effectiveness of geriatrics curricular innovations using validated knowledge and attitude outcomes in a longitudinal controlled study design and will be useful to other medical institutions seeking to improve the geriatrics knowledge and attitudes of their students.

Are medical students' views of an ideal physician eroding? A study on perceived qualities of a "role model" doctor before and after housemanship and between two cohorts five years apart

INTRODUCTION

This study aimed to examine the impact of housemanship and cohort effect on the perceptions of what constitutes a "role model physician" between 2 cohorts of medical students.

MATERIALS & METHODS

Final year medical students of the Yong Loo Lin School of Medicine, National University of Singapore, from the classes of 2005 (pre- and post-housemanship) and class of 2009 (pre-housemanship) responded to an anonymous 25-statement questionnaire reflecting Fones et al's 25-item characterisation of a "role model" doctor. Qualitative data was also collected on student's perceived qualities of a role model doctor.

RESULTS

For the 2005 cohort pre- and post-housemanship, only 3 of the 25 items had increased in importance post-housemanship. However, when comparing the 2005 and 2009 cohorts pre-housemanship, the latter cohort placed significantly greater importance on 12 of the 25 items. Willingness to teach was identified via qualitative analysis as a new important quality of a role model doctor for medical students.

CONCLUSION

The importance placed on characteristics of "role model" physicians were relatively unchanged by housemanship within the same cohort but increased with time between 2 cohorts 5 years apart. This suggests that professional standards of an "ideal" doctor expected and aspired to by medical students may not be eroding as feared by the medical profession and society.

Overcoming Barriers to Mammography Screening: A Quasi-randomised Pragmatic Trial in a Community-based Primary Care Setting

INTRODUCTION

Breast cancer is the leading cancer among women in Singapore. Five years after a population-wide breast cancer screening programme was introduced, screening rates remained relatively low at 41%. Studies have shown decreased screening propensity among medically underserved women typically of minority or socioeconomically disadvantaged status. We conducted a quasi-randomised pragmatic trial aimed at encouraging mammography screening among underscreened or unscreened women in a publicly funded primary care facility in Singapore.

MATERIALS AND METHODS

The study was conducted from May to August 2010. Components of intervention included (1) tailored education, (2) doctor's reminder, and (3) cost reduction. Researchers administered a structured questionnaire to eligible female polyclinic attendees and patient companions aged 40 to 69 years. Individual knowledge, attitudes, beliefs, and barriers towards mammography screening were identified and educational messages tailored. Doctor's reminder and cost reduction were implemented additively.

RESULTS

Overall, out of 448 participants, 87 (19.4%, 95% confidence interval (CI), 15.8% to 23.1%) completed mammography screening across 3 arms of study. Participants who received a cost reduction were more likely to attend screening compared to participants in other intervention arms (adjusted odds ratio (OR) 2.4, 95% CI, 1.2 to 4.5, P = 0.009). Cost of screening, ethnicity, prior screening history, and attitudes towards mammography screening were identified as significant factors predicting mammogram attendance.

CONCLUSION

Including a cost reduction component was the most effective intervention that increased mammography screening rates. Women's underlying beliefs, attitudes, and other predisposing factors should also be considered for integration into existing breast cancer screening programmes.

Postoperated hip fracture rehabilitation effectiveness and efficiency in a community hospital

INTRODUCTION

This study aims to determine the inpatient rehabilitation effectiveness (REs) and rehabilitation efficiency (REy) of hip fracture in a Singapore community hospital (CH), its association with socio-demographic variables, medical comorbidities and admission Shah-modified Barthel Index (BI) score as well as change in independent ambulation from discharge to 4 months later.

MATERIALS AND METHODS

A retrospective cohort study using data manually extracted from medical records of all patients who had hip fracture within 90 days and admitted to a CH after the operation for rehabilitation. Multiple linear regressions are used to identify independent predictors of REs and REy.

RESULTS

The mean REs was 40.4% (95% Confidence Interval (CI), 36.7 to 44.0). The independent predictors of poorer REs on multivariate analysis were older age, Malay (vs non-Malay) patients, fewer numbers of rehabilitative therapy sessions and dementia. The mean REy was 0.41 units per day [CI, 0.36 to 0.46]. The independent predictors of poorer REy on multivariate analysis were higher admission BI and being non-hypertensive patient. The prevalence of independent ambulation improved from 78.9% at the discharge to 88.3% 4 months later.

CONCLUSION

CH inpatient rehabilitative therapy showed REs 40.4% and REy of 0.41 units per day and the optimum number of rehabilitative therapy session was from 28 to 41 in terms of rehabilitation effectiveness and the maximum rehabilitation efficiency was seen in those doing 14 to 27 sessions of rehabilitative therapy. The study also showed improvement in BI at discharge and improvement in the independent ambulation 4 months after discharge from the CH.

Post community hospital discharge rehabilitation attendance: Self-perceived barriers and participation over time

INTRODUCTION

This study aimed to examine the attendance rates of post-discharge supervised rehabilitation as recommended by the multidisciplinary team at discharge among subacutely disabled adults and the barriers preventing adherence.

MATERIALS AND METHODS

Patients were from a community hospital, aged 40 years or older. They had been assessed by a multidisciplinary team to benefit from rehabilitation after discharge, were mentally competent and communicative. We used a sequential qualitative-quantitative mixed methods study design. In the initial qualitative phase, we studied the patient-perceived barriers to adherence to rehabilitation using semi-structured interviews. Emerging themes were then analysed and used to develop a questionnaire to measure the extent of these barriers. In the subsequent quantitative phase, the questionnaire was used with telephone follow-up at 3, 6, 9 and 12 months after discharge.

RESULTS

Qualitative phase interviews (n = 41) revealed specific perceived financial, social, physical and health barriers. At the start of the quantitative phase (n = 70), 87.1% of the patients viewed rehabilitation as beneficial, but overall longitudinal attendance rate fell from 100% as inpatient to 20.3% at 3 months, 9.8% at 6 months, 6.3% at 9 months and 4.3% at 12 months. The prevalence of physical and social barriers were high initially but decreased with time. In contrast, the prevalence of financial and perceptual barriers increased with time.

CONCLUSION

Attendance of post-hospitalisation rehabilitation in Singapore is low. Self-perceived barriers to post-discharge rehabilitation attendance were functional, social, financial and perceptual, and their prevalence varied with time.

Factors associated with nursing home placement of all patients admitted for inpatient rehabilitation in Singapore community hospitals from 1996 to 2005: a disease stratified analysis

OBJECTIVES

To (1) identify social and rehabilitation predictors of nursing home placement, (2) investigate the association between effectiveness and efficiency in rehabilitation and nursing home placement of patients admitted for inpatient rehabilitation from 1996 to 2005 by disease in Singapore.

DESIGN

National data were retrospectively extracted from medical records of community hospital.

DATA SOURCES

There were 12,506 first admissions for rehabilitation in four community hospitals. Of which, 8,594 (90.3%) patients were discharged home and 924 (9.7%) patients were discharged to a nursing home. Other discharge destinations such as sheltered home (n = 37), other community hospital (n = 31), death in community hospital (n = 12), acute hospital (n = 1,182) and discharge against doctor's advice (n = 24) were excluded.

OUTCOME MEASURE

Nursing home placement.

RESULTS

Those who were discharged to nursing home had 33% lower median rehabilitation effectiveness and 29% lower median rehabilitation efficiency compared to those who were discharged to nursing homes. Patients discharged to nursing homes were significantly older (mean age: 77 vs. 73 years), had lower mean Bathel Index scores (40 vs. 48), a longer median length of stay (40 vs. 33 days) and a longer time to rehabilitation (19 vs. 15 days), had a higher proportion without a caregiver (28 vs. 7%), being single (21 vs. 7%) and had dementia (23 vs. 10%). Patients admitted for lower limb amputation or falls had an increased odds of being discharged to a nursing home by 175% (p<0.001) and 65% (p = 0.043) respectively compared to stroke patients.

CONCLUSIONS

In our study, the odds of nursing home placement was found to be increased in Chinese, males, single or widowed or separated/divorced, patients in high subsidy wards for hospital care, patients with dementia, without caregivers, lower functional scores at admission, lower rehabilitation effectiveness or efficiency at discharge and primary diagnosis groups such as fractures, lower limb amputation and falls in comparison to strokes.

Hypertension management and lifestyle changes following screening for hypertension in an Asian low socioeconomic status community: a prospective study

INTRODUCTION

This study investigated the effect of an access-enhanced intervention on hypertension screening and management, as well as on health behaviours among newly diagnosed hypertensives, in a multi-ethnic low socioeconomic status (SES) community. Factors associated with hypertension screening, treatment, and control in the community were also determined.

MATERIALS AND METHODS

The study involved all residents aged ≥40 years in 2 public rental housing precincts (low SES), between 2009 and 2011, who were followed-up prospectively for 1 year after a 6-month community-based intervention comprising a 3-month access-enhanced screening component and a 3-month follow-up (outreach) component. Blood pressure was measured at baseline and follow-up. Multivariate Cox regression determined predictors of hypertension management at follow-up.

RESULTS

The follow-up rate was 80.9% (467/577). At baseline, 60.4% (282/467) were hypertensive; 53.5% (151/282) were untreated; 54.2% (71/131) uncontrolled. One year later, postintervention, 51.6% (78/151) of untreated hypertensives were treated; combined with treated hypertensives previously uncontrolled, 53.0% (79/149) achieved control. Older age independently predicted treatment (adjusted relative risk, aRR = 1.98, CI, 1.08 to 3.65); majority ethnicity (aRR = 1.76, CI, 1.05 to 2.96), employment (aRR = 1.85, CI, 1.26 to 2.80) and newly treated hypertension (aRR=1.52, CI, 1.01 to 2.32) predicted control. A total of 52.4% (97/185) were irregularly screened at baseline; at follow-up 61.9% (60/97) were regularly screened. Cost and misperceptions were common barriers to screening and treatment. Newly diagnosed hypertensives were also less likely to go for additional cardiovascular screening (aRR = 0.54, CI, 0.29 to 0.99).

CONCLUSION

An access-enhanced intervention had some success in improving hypertension management within low SES communities; however, it was less successful in improving cardiovascular risk management, especially in encouraging lifestyle changes and additional cardiovascular screening amongst newly diagnosed hypertensives.

Socio-demographic and clinical profile of admissions to community hospitals in Singapore from 1996 to 2005: a descriptive study

INTRODUCTION

Little data is available on community hospital admissions. We examined the differences between community hospitals and the annual trends in sociodemographic characteristics of all patient admissions in Singaporean community hospitals over a 10- year period from 1996 to 2005.

MATERIALS AND METHODS

Data were manually extracted from medical records of 4 community hospitals existent in Singapore from 1996 to 2005. Nineteen thousand and three hundred and sixty patient records were examined. Chisquare test was used for univariate analysis of categorical variables by type of community hospitals. For annual trends, test for linear by linear association was used. ANOVA was used to generate beta coefficients for continuous variables.

RESULTS

Mean age of all patient admissions has increased from 72.8 years in 1996 to 74.8 years in 2005. The majority was Chinese (88.4%), and female (58.1%) and admissions were mainly for rehabilitation (88.0%). Almost one third had foreign domestic workers as primary caregivers and most (73.5%) were discharged to their own home. There were significant differences in socio-demographic profile of admissions between hospitals with one hospital having more patients with poor social support. Over the 10-year period, the geometric mean length of stay decreased from 29.7 days (95% CI, 6.4 to 138.0) to 26.7 days (95% CI, 7.5 to 94.2), and both mean admission and discharge Barthel Index scores increased from 41.0 (SD = 24.9) and 51.8 (SD = 30.0), respectively in 1996 to 48.4 (SD = 24.5) and 64.2 (SD = 27.3) respectively in 2005.

CONCLUSION

There are significant differences in socio-demographic characteristics and clinical profile of admissions between various community hospitals and across time. Understanding these differences and trends in admission profiles may help in projecting future healthcare service needs.

The knowledge-attitude dissociation in geriatric education: can it be overcome?

INTRODUCTION

A knowledge-attitude dissociation often exists in geriatrics where knowledge but not attitudes towards elderly patients improve with education. This study aims to determine whether a holistic education programme incorporating multiple educational strategies such as early exposure, ageing simulation and small group teaching results in improving geriatrics knowledge and attitudes among medical students.

MATERIALS AND METHODS

We administered the 18-item University of California Los Angeles (UCLA) Geriatric Knowledge Test (GKT) and the Singapore-modified 16-item UCLA Geriatric Attitudes Test (GAT) to 2nd year students of the old curriculum in 2009 (baseline reference cohort, n = 254), and before and after the new module to students of the new curriculum in 2010 (intervention cohort, n = 261), both at the same time of the year.

RESULTS

At baseline, between the baseline reference and intervention cohort, there was no difference in knowledge (UCLA-GKT Score: 31.6 vs 33.5, P = 0.207) but attitudes of the intervention group were worse than the baseline reference group (UCLA-GAT Score: 3.53 vs 3.43, P = 0.003). The new module improved both the geriatric knowledge (UCLA-GKT Score: 34.0 vs 46.0, P <0.001) and attitudes (UCLA-GAT Score: 3.43 vs 3.50, P <0.001) of the intervention cohort.

CONCLUSION

A geriatric education module incorporating sound educational strategies improved both geriatric knowledge and attitudes among medical students.

Comparison of neutralizing antibody and cell-mediated immune responses to pandemic H1N1 2009 influenza virus before and after H1N1 2009 influenza vaccination of elderly subjects and healthcare workers

BACKGROUND

The recent H1N1 pandemic virus that emerged in 2009 resulted in high morbidity rates mainly in younger individuals, albeit with relatively low mortality. We investigated both humoral and cellular immune responses against the pandemic H1N1 2009 virus before and after immunization with inactivated H1N1 2009 vaccine.

METHODS

We obtained paired blood specimens from a cohort of participants from nursing homes (n=108) and a public hospital (n=60) in Singapore. Serum samples were tested for neutralizing antibodies against H1N1 2009 using microneutralization assays, while peripheral blood mononuclear cells were subjected to interferon-γ enzyme-linked immunosorbent spot (ELISPOT) assays for whole virus-specific T-cell responses.

RESULTS

We observed significant increases in geometric mean titers of neutralizing antibodies after H1N1 2009 vaccination (from 23.6 pre-vaccination to 94.7 post-vaccination). Approximately 77% and 54% of the cohort exhibited ≥2-fold and ≥4-fold increases in neutralizing antibody titers following vaccination; 89.9% of the cohort had a post-vaccination antibody titer of ≥32. Adjusted for gender, participants aged ≥60 years were less likely to have a ≥4-fold increase in antibody titers after vaccination than those aged <60 years (0.48; 95% confidence interval (95% CI) 0.32-0.71, p=0.007). There was a 1.4-fold elevation in H1N1 2009-specific T-cell responses after vaccination (p<0.05). Adjusted for gender, age ≥60 years was positively associated with a greater increase in T-cell response (β=4.9, 95% CI 1.58-8.29, p=0.018). No significant correlation was observed between humoral and cellular immune responses.

CONCLUSIONS

Influenza vaccination elicits significant neutralizing antibody and T-cell responses to pandemic H1N1 2009 influenza virus. However, in response to vaccination, increases in neutralizing antibody titers were comparatively lower but T-cell responses were higher in older participants. Therefore, our study suggests that memory T-cells may play a crucial role in protecting older individuals against pandemic H1N1 2009 infection.

Colorectal cancer screening: the effectiveness of education on its barriers and acceptability

To assess the awareness and acceptability of colorectal cancer (CRC) screening in noncompliant Singaporeans and to determine if their barriers can be overcome by education. A questionnaire developed from thematic analysis of open-ended interviews with 72 subjects was administered to 580 residents in a local high-rise housing estate. Participants aware of CRC screening were assessed for barriers and acceptability of CRC screening. All participants were subsequently educated about CRC screening and reassessed for barriers and acceptance. Those keen for fecal occult blood testing (FOBT) were offered FOBT kits and followed up. CRC screening awareness was poor. Having no symptoms was the most common barrier. More barriers to FOBT than to colonoscopy were reduced with education. After education, acceptability toward FOBT increased but rejection rates rose even higher. FOBT is probably Singapore's most acceptable screening modality. Education is limited by barriers, which need to be overcome by alternative measures.

Multi-disease health screening in an urban low-income setting: a community-based study

INTRODUCTION

We were interested to determine the participation rates for health screening in a multi-ethnic urban low-income community. We assessed the health screening rates at baseline, collected data on reasons for non-participation and assessed the impact that a 5-month intervention had on health screening in this community.

MATERIALS AND METHODS

The study population involved all residents aged ≥40 years, living in heavily subsidised public rental flats in Taman Jurong Constituency, Singapore. From January 2009 to May 2009, we collected baseline information and offered eligible residents free blood pressure, fasting blood glucose and lipid measurements, fecal occult blood testing and Pap smears. Screenings were conducted either at or near the residents' homes.

RESULTS

The participation rate was 60.9% (213/350). At baseline, 18.9% (24/127), 26.4% (42/159) and 18.7% (31/166) had gone for regular hypertension, diabetes and hyperlipidaemia screening, respectively; 3.8% (6/157) and 2.9% (2/70) had had regular colorectal and cervical cancer screening, respectively. Post-intervention, rates for hypertension screening increased to 97.6% but increases for other modalities were marginal. High cost, lack of time, not at risk, too old, or unnecessary for healthy people were commonly-cited reasons for skipping regular health screening. Being unemployed was associated with missing regular hypertension screening (adjusted OR = 2.48, CI = 1.12-5.53, P = 0.026); those who did not need financial aid were less likely to miss regular hyperlipidaemia screening (adjusted OR = 0.27, CI = 0.10-0.72, P = 0.008).

CONCLUSION

The participation rates for health screening were poor in this low-income community. More can be done to encourage regular health screening participation amongst this segment of the populace, both by reducing costs as well as addressing misperceptions.

The Pedagogical Value of a Student-run Community-based Experiential Learning Project: The Yong Loo Lin School of Medicine Public Health Screening

Introduction: We assessed the pedagogical value of a student-led community-based experiential learning project called the Public Health Screening (PHS) run by medical and nursing students of the National University of Singapore’s Yong Loo Lin School of Medicine (NUS YLLSoM). Materials and Methods: We conducted a cross-sectional study using a self-administered anonymised questionnaire on medical and nursing students who participated in PHS using the Fund for the Improvement of Postsecondary Education (FIPSE) Survey Instrument. Participants also gave an overall score for their learning experience at the PHS. Results: The participation rate was 93.1% (576/619) for medical students and 100% (37/37) for nursing students. All participants gave the PHS learning experience a high rating (median = 8 out of maximum of 10, inter-quartile range, 7 to 9). A majority of participants felt that PHS had helped them to improve across all domains surveyed. For medical students, those in preclinical years and females were independently more likely to feel that PHS had helped them to improve in communication skills, teamwork, ability to identify social issues, taking action, and gaining and applying their knowledge than those in clinical years and males. Improved ability to interact with patients (β=1.64, 95%CI, 1.01-2.27), appreciation of challenges to healthcare faced by Singaporeans from lower income groups (β=0.93, 95%CI, 0.49-1.37), thinking of others (β=0.70, 95%CI, 0.04-1.37) and tolerance of different people (β =0.63, 95%CI, 0.17-1.10) were strongly associated with the overall rating score. Conclusion: PHS was a positive learning experience in a wide range of domains for all students involved. This suggests that student-organised community-based experiential learning projects have potential educational value for both medical and nursing students.

CONCLUSION

PHS was a positive learning experience in a wide range of domains for all students involved. This suggests that student-organised community-based experiential learning projects have potential educational value for both medical and nursing students.

Serological response in RT-PCR confirmed H1N1-2009 influenza a by hemagglutination inhibition and virus neutralization assays: an observational study

BACKGROUND

We describe the serological response following H1N1-2009 influenza A infections confirmed by reverse-transcriptase polymerase chain reaction (RT-PCR).

METHODOLOGY AND PRINCIPAL FINDINGS

The study included patients admitted to hospital, subjects of a seroepidemiologic cohort study, and participants identified from outbreak studies in Singapore. Baseline (first available blood sample) and follow-up blood samples were analyzed for antibody titers to H1N1-2009 and recently circulating seasonal influenza A virus strains by hemagglutination inhibition (HI) and virus micro-neutralization (VM) assays. 267 samples from 118 cases of H1N1-2009 were analyzed. Geometric mean titers by HI peaked at 123 (95% confidence interval, CI 43-356) between days 30 to 39. The chance of observing seroconversion (four-fold or greater increase of antibodies) was maximized when restricting analysis to 45 participants with baseline sera collected within 5 days of onset and follow-up sera collected 15 or more days after onset; for these participants, 82% and 89% seroconverted to A/California/7/2009 H1N1 by HI and VM respectively. A four-fold or greater increase in cross-reactive antibody titers to seasonal A/Brisbane/59/2007 H1N1, A/Brisbane/10/2007 H3N2 and A/Wisconsin/15/2009 H3N2 occurred in 20%, 18% and 16% of participants respectively.

CONCLUSIONS AND SIGNIFICANCE

Appropriately timed paired serology detects 80-90% RT-PCR confirmed H1N1-2009; Antibodies from infection with H1N1-2009 cross-reacted with seasonal influenza viruses.

Acceptability of medical students by patients from private and public family practices and specialist outpatient clinics

INTRODUCTION

Previous studies on patient acceptance of medical student teaching were from Western populations and in one setting only. However, there has been no prospective study comparing patient acceptability before and after an actual experience. We studied patient acceptability of medical student teaching in private and public family practices and public hospital specialist outpatient clinics in Singapore, and before and after an actual medical student teaching consultation.

MATERIALS AND METHODS

We conducted an anonymous cross-sectional survey from March through October 2007 of Singaporean or permanent resident patients attending 76 teaching private family practices, 9 teaching public family practices and 8 specialty clinics in a teaching public hospital. We used pre-consultation cross-sectional patient surveys in all three settings. For private family practice setting only, post-consultation patient survey was conducted after an actual experience with medical student presence.

RESULTS

Out of 5123 patients, 4142 participated in the cross-sectional survey (80.9%) and 1235 of 1519 patients in the prospective cohort study (81.3%). Eighty percent were comfortable with medical students present, 79% being interviewed and 60% being examined. Regarding being examined by medical students, parents of children were least comfortable while patients between 41 to 60 years were most comfortable (adjusted OR = 1.99 [1.55-2.57]). Females were less comfortable with medical student teaching than males. Chinese patients were the least comfortable about being interviewed or examined by medical students among the ethnic groups. Indians were most comfortable with being interviewed by medical students (adjusted OR = 1.38 [1.02-1.86]) but Malays were the most comfortable being examined by them (adjusted OR = 1.32 [1.07-1.62]). Family practice patients were more receptive to medical student teaching than the hospital's specialist outpatients. Common barriers to patient acceptance were lack of assurance of patient privacy, dignity and confidentiality. Actual exposure to medical student teaching did not change levels of patient acceptance.

CONCLUSIONS

Compared to similar studies from Western countries, Asian patients appear to be less receptive to medical student teaching than Western patients. Family practice settings offer medical students a more receptive learning environment.

2009 influenza A(H1N1) seroconversion rates and risk factors among distinct adult cohorts in Singapore

CONTEXT

Singapore experienced a single epidemic wave of 2009 influenza A(H1N1) with epidemic activity starting in late June 2009 and peaking in early August before subsiding within a month.

OBJECTIVE

To compare the risk and factors associated with H1N1 seroconversion in different adult cohorts.

DESIGN, SETTING, AND PARTICIPANTS

A study with serial serological samples from 4 distinct cohorts: general population (n = 838), military personnel (n = 1213), staff from an acute care hospital (n = 558), and staff as well as residents from long-term care facilities (n = 300) from June 22, 2009, to October 15, 2009. Hemagglutination inhibition results of serum samples taken before, during, and after the epidemic and data from symptom questionnaires are presented.

MAIN OUTCOME MEASURES

A 4-fold or greater increase in titer between any of the 3 serological samples was defined as evidence of H1N1 seroconversion.

RESULTS

Baseline titers of 40 or more were observed in 22 members (2.6%; 95% confidence interval [CI], 1.7%-3.9%) of the community, 114 military personnel (9.4%; 95% CI, 7.9%-11.2%), 37 hospital staff (6.6%; 95% CI, 4.8%-9.0%), and 20 participants from long-term care facilities (6.7%; 95% CI, 4.4%-10.1%). In participants with 1 or more follow-up serum samples, 312 military personnel (29.4%; 95% CI, 26.8%-32.2%) seroconverted compared with 98 community members (13.5%; 95% CI, 11.2%-16.2%), 35 hospital staff (6.5%; 95% CI, 4.7%-8.9%), and only 3 long-term care participants (1.2%; 95% CI, 0.4%-3.5%). Increased frequency of seroconversion was observed for community participants from households in which 1 other member seroconverted (adjusted odds ratio [OR], 3.32; 95% CI, 1.50-7.33), whereas older age was associated with reduced odds of seroconversion (adjusted OR, 0.77 per 10 years; 95% CI, 0.64-0.93). Higher baseline titers were associated with decreased frequency of seroconversion in community (adjusted OR for every doubling of baseline titer, 0.48; 95% CI, 0.27-0.85), military (adjusted OR, 0.71; 95% CI, 0.61-0.81), and hospital staff cohorts (adjusted OR, 0.50; 95% CI, 0.26-0.93).

CONCLUSION

Following the June-September 2009 wave of 2009 influenza A(H1N1), 13% of the community participants seroconverted, and most of the adult population likely remained susceptible.

Knowledge and practice of household mosquito breeding control measures between a dengue hotspot and non-hotspot in Singapore

INTRODUCTION

The aim of this study was to compare the knowledge and practices of household mosquito-breeding control measures between a dengue hotspot (HS) and a non-hotspot (NHS).

MATERIALS AND METHODS

Eight hundred households were randomly sampled from HS and NHS areas, and an National Environment Agency (NEA) questionnaire was administered to heads of the households. Interviewers were blinded to the dengue status of households. We included subjects aged above 16 years, who were communicative and currently living in the household. Chi-square test was used to compare proportions and multiple logistic regression was used to adjust for socio-demographic differences between both areas.

RESULTS

The overall response rate was 59.0% (n = 472). There were significant differences in gender, educational level, employment status and housing type between HS and NHS (all P <0.05). NHS residents were less knowledgeable in 6 out of 8 NEA-recommended anti-mosquito breeding actions: changing water in vase/bowls [AOR (adjusted OR), 0.20; CI, 0.08-0.47; P <0.01], adding sand granular insecticide to water [AOR, 0.49; CI, 0.31-0.71; P <0.01], turning over pails when not in use [AOR, 0.39; CI, 0.17-0.89; P = 0.02], removing flower pot/plates [AOR, 0.35; CI, 0.18-0.67; P <0.01], removing water in flower pot/plates [AOR, 0.36; CI, 0.17-0.75; P <0.01] and putting insecticide in roof gutters [AOR 0.36; CI, 0.13-0.98; P = 0.04]. Hotspot residents reported better practice of only 2 out of 8 NEA-recommended mosquito-breeding control measures: changing water in vases or bowls on alternate days [AOR, 2.74; CI, 1.51-4.96; P <0.01] and removing water from flower pot plates on alternate days [AOR, 1.95; CI, 1.01-3.77; P = 0.05].

CONCLUSION

More HS residents were knowledgeable and reported practicing mosquito-breeding control measures compared to NHS residents. However, a knowledge-practice gap still existed.

An association between floor vacuuming and dust-mite and serum eosinophil cationic protein in young asthmatics

Although vacuum cleaning is recommended to reduce allergen levels and improve asthma and allergic rhinitis symptoms, some studies suggest it may increase allergen load in homes. We conducted a cross-sectional study to determine if home floor vacuuming was associated with sensitization to dust-mites and cockroaches, and serum eosinophil cationic protein (ECP), a biomarker for atopy, in 102 physician-diagnosed spirometry-confirmed asthmatics. We collected data on floor type, floor cleaning method and frequency, asthma severity, allergy medications used, serum ECP and skin prick tests (SPT) to three dust-mites [Dermatophagoides pteronyssisinus (Der p), Dermatophagoides farinae (Der f) and Blomia tropicalis (Blo t)] and two cockroaches [Periplanata americana (Per a) and Blatella germanica (Bla g)]. Those who vacuumed had increased sensitization to three dust-mites [adjusted ORs (95%CI) = Der p: 26.6 (1.8-405.2); Der f: 44.8 (3.2-620.9); Blo t: 14.1 (1.8-108.1)] but not to cockroaches, adjusted for cleaning frequency and other methods of floor cleaning. Subjects who vacuumed their floor had higher levels of serum ECP than those who did not [adjusted median difference (95%CI): 9.4 (1.1-17.7)], adjusted for use of nasal corticosteroids among those with allergic rhinitis. Vacuuming is associated with increased sensitization to dust-mite allergens and higher serum ECP.

PRACTICAL IMPLICATIONS

We found an association between floor vacuuming and increased sensitization to dust-mite allergens and higher levels of an atopy biomarker. Current recommendations to use vacuuming to control allergen exposure and allergic conditions may need to be reconsidered until further studies are performed.

Attitudes towards the elderly among Singapore medical students

INTRODUCTION

It is important that medical students possess the correct attitude towards the elderly and not have an ageist attitude. This is because they will be caring for an increasing proportion of elderly patients. We thus sought to assess the attitudes of our medical students towards the elderly.

MATERIALS AND METHODS

We conducted a cross-sectional study assessing the attitudes towards the elderly of 225 fi rst-year and 135 third-year students using a self-administered questionnaire that incorporated the Kogan's Attitudes Toward Old People Scale (KAOP). Elderly people were defined as those aged 65 years and above for this study.

RESULTS

The majority of fi rst- (98.2%) and third-year (99.2%) medical students had positive attitudes towards elderly people (KAOP score above 102). KAOP scores were not significantly different regardless of seniority (medical student year), gender, race, household income, or having a doctor-parent. Although the mean KAOP score of third-year students was higher than that of fi rst-year students, this was not significantly different (P = 0.062).

CONCLUSIONS

Medical students in Singapore have a positive attitude towards the elderly. It is important that their medical curriculum continues to have an increasing geriatric component in view of the increasing numbers of older persons that they will be caring for due to the ageing population.

Avian Influenza: a global threat needing a global solution

There have been three influenza pandemics since the 1900s, of which the 1919-1919 flu pandemic had the highest mortality rates. The influenza virus infects both humans and birds, and mutates using two mechanisms: antigenic drift and antigenic shift. Currently, the H5N1 avian flu virus is limited to outbreaks among poultry and persons in direct contact to infected poultry, but the mortality rate among infected humans is high. Avian influenza (AI) is endemic in Asia as a result of unregulated poultry rearing in rural areas. Such birds often live in close proximity to humans and this increases the chance of genetic re-assortment between avian and human influenza viruses which may produce a mutant strain that is easily transmitted between humans. Once this happens, a global pandemic is likely. Unlike SARS, a person with influenza infection is contagious before the onset of case-defining symptoms which limits the effectiveness of case isolation as a control strategy. Researchers have shown that carefully orchestrated of public health measures could potentially limit the spread of an AI pandemic if implemented soon after the first cases appear. To successfully contain and control an AI pandemic, both national and global strategies are needed. National strategies include source surveillance and control, adequate stockpiles of anti-viral agents, timely production of flu vaccines and healthcare system readiness. Global strategies such as early integrated response, curbing the disease outbreak at source, utilization of global resources, continuing research and open communication are also critical.

A cross-sectional study of primary-care physicians in Singapore on their concerns and preparedness for an avian influenza outbreak

INTRODUCTION

During an avian influenza (AI) pandemic, primary-care physicians (PCPs) are expected to play key roles in the prevention and control of the disease. Different groups of PCPs could have different concerns and preparedness level. We assessed the concerns, perceived impact and preparedness for an outbreak among PCPs in Singapore.

MATERIALS AND METHODS

A cross-sectional survey of PCPs working in private practice (n=200) and public clinics (n=205) from March to June 2006 with an anonymous self-administered questionnaire on concerns (12- items), perceived impact (10 items) and preparedness (10 items) for an outbreak.

RESULTS

Two hundred and eighty-five PCPs responded - 149 (response rate: 72.7%) public and 136 (response rate: 67.3%) private. The majority were concerned about risk to their health from their occupation (95.0%) and falling ill with AI (89.7%). Most (82.5%) accepted the risk and only 33 (11.8%) would consider stopping work. For perceived impact, most felt that people would avoid them (69.6%) and their families (54.1%). The majority (81.3%) expected an increased workload and feeling more stressed at work (86.9%). For preparedness, 78.7% felt personally prepared for an outbreak. Public PCPs were more likely to be involved in infection-control activities and felt that their workplaces were prepared.

CONCLUSIONS

Most PCPs felt personally prepared for an outbreak but were concerned about their exposure to AI and falling ill. Other concerns included social ostracism for themselves and their families. Public PCPs appeared to have a higher level of preparation. Addressing concerns and improving level of preparedness are crucial to strengthen the primary-care response for any AI outbreak.

A review of geriatric education in Singapore

The United Nations has identified the training and education of healthcare professionals and care providers involved in the care of older persons as a global priority. Singapore is no exception as it faces a rapidly ageing population. Older people have many medical needs of varying dimensions and their care requires a multidisciplinary healthcare team. The current status of geriatric education of health professionals involved in elderly care in Singapore is discussed in this paper. Important issues raised include the disparity between professions in the stages of development of geriatric education, questions on the adequacy of numbers and training of healthcare professionals providing geriatric care, as well as the need for geriatric education of caregivers.

Determinants of length of stay during post-stroke rehabilitation in community hospitals

INTRODUCTION

Length of stay (LOS) in hospitals is the largest contributor of direct stroke care cost. Rehabilitation accounts for 16 percent of healthcare cost in the six-month post-stroke period. It is important to determine factors extending LOS in rehabilitation hospitals to identify focus areas of cost-control strategies. The aim of the study was to ascertain the predictors of LOS of post-stroke patients admitted into two community hospitals offering rehabilitation.

METHODS

An observational cohort study was conducted on 200 stroke patients admitted from acute hospitals into two community hospitals. Data collected included baseline sociodemographical variables, and the National Institute of Health Stroke Scale, Abbreviated Mental Test, Geriatric Depression Scale and Barthel Index were used to assess neurological impairment, cognitive impairment, depressive symptoms and functional disability, respectively. Medical complications (defined as new or exacerbated medical problems that generated additional physician evaluation, a change in medication or additional medical intervention), after patients were admitted to the community hospitals until discharged, were recorded. The outcome variables measured were length and cost of stay.

RESULTS

The mean LOS in our study was 34.4 (standard deviation [SD] 18.4) days, and the mean cost of hospital stay was S$2,410.83 (SD S$2,167.26). Length and cost of hospital stay were significantly correlated (r equals 0.52; p-value is less than 0.01). On multiple linear regression analysis, the significant variables positively associated with LOS were medical complications and functional dependence on admission. Significant variables negatively associated with LOS were unplanned discharge and recurrent strokes.

CONCLUSION

Medical complication is a key reversible determinant of increased LOS of post-stroke patients receiving rehabilitation in community hospitals. Strategies for prevention, early detection and treatment of medical complications during stroke rehabilitation are discussed.
