Values and health care: the Confucian dimension in health care reform.

Are values and social priorities universal, or do they vary across geography, culture, and time? This question is very relevant to Asia's emerging economies that are increasingly looking at Western models for answers to their own outmoded health care systems that are in dire need of reform. But is it safe for them to do so without sufficient regard to their own social, political, and philosophical moorings? This article argues that historical and cultural legacies influence prevailing social values with regard to health care financing and resource allocation, and that the Confucian dimension provides a helpful entry point for a deeper understanding of ongoing health care reforms in East Asia--as exemplified by the unique case of Singapore.

National policy-makers speak out: are researchers giving them what they need?

The objective of this empirical study was to understand the perspectives and attitudes of policy-makers towards the use and impact of research in the health sector in low- and middle-income countries. The study used data from 83 semi-structured, in-depth interviews conducted with purposively selected policy-makers at the national level in Argentina, Egypt, Iran, Malawi, Oman and Singapore. The interviews were structured around an interview guide developed based on existing literature and in consultation with all six country investigators. Transcripts were processed using a thematic-analysis approach. Policy-makers interviewed for this study were unequivocal in their support for health research and the high value they attribute to it. However, they stated that there were structural and informal barriers to research contributing to policy processes, to the contribution research makes to knowledge generally, and to the use of research in health decision-making specifically. Major findings regarding barriers to evidence-based policy-making included poor communication and dissemination, lack of technical capacity in policy processes, as well as the influence of the political context. Policy-makers had a variable understanding of economic analysis, equity and burden of disease measures, and were vague in terms of their use in national decisions. Policy-maker recommendations regarding strategies for facilitating the uptake of research into policy included improving the technical capacity of policy-makers, better packaging of research results, use of social networks, and establishment of fora and clearinghouse functions to help assist in evidence-based policy-making.

Singapore's response to the severe acute respiratory syndrome outbreak: what do Singapore physicians think?

OBJECTIVE: To gauge Singapore physicians' perceptions of the national response to the severe acute respiratory syndrome (SARS) outbreak using a questionnaire survey. METHODS: Random sampling was applied to draw the survey population. Descriptive analysis and logistic regressions were used. RESULTS: The majority of physicians agreed that home quarantine of contacts of patients with probable SARS was warranted (95%), government's public education effort was effective (83%), and the overall Singapore's response was commendable (82%). Only 38%, however, agreed that health care workers were supplied with timely and adequate personal protective equipment. CONCLUSIONS: Most Singapore physicians have positive comments about the national response to the SARS crisis. However, systematic weaknesses are identified and recommendations are presented.

Drugs, sex, money and power: an HPV vaccine case study.

In this paper we compare the experiences of seven industrialized countries in considering approval and introduction of the world's first cervical cancer-preventing vaccine. Based on case studies, articles from public agencies, professional journals and newspapers we analyse the public debate about the vaccine, examine positions of stakeholder groups and their influence on the course and outcome of this policy process. The analysis shows that the countries considered here approved the vaccine and established related immunization programs exceptionally quickly even though there still exist many uncertainties as to the vaccine's long-term effectiveness, cost-effectiveness and safety. Some countries even bypassed established decision-making processes. The voice of special interest groups has been prominent in all countries, drawing on societal values and fears of the public. Even though positions differed among countries, all seven decided to publicly fund the vaccine, illustrating a widespread convergence of interests. It is important that decision-makers adhere to transparent and robust guidelines in making funding decisions in the future to avoid capture by vested interests and potentially negative effects on access and equity.

Comparison of estimates of under-nutrition for pre-school rural Pakistani children based on the WHO standard and the National Center for Health Statistics (NCHS) reference.

OBJECTIVE: To compare estimates of under-nutrition among pre-school Pakistani children using the WHO growth standard and the National Center for Health Statistics (NCHS) reference. DESIGN: Prevalence of stunting, wasting and underweight as defined by WHO and NCHS standards are calculated and compared. SETTING: The data are from two cross-sectional surveys conducted in the early 1990s, the time frame for setting the baseline for the Millennium Development Goals: (i) National Health Survey of Pakistan (NHSP) assessed the health status of a nationally representative sample and (ii) Thatta Health System Research Project (THSRP) was a survey in Thatta, a rural district of Sindh Province. SUBJECTS: In all, 1533 and 1051 children aged 0-35 months from national and Thatta surveys, respectively. RESULTS: WHO standard gave a significantly higher prevalence of stunting for both national [36.7 (95 % CI 33.2, 40.2)] and Thatta surveys [52.9 (95 % CI 48.9, 56.9)] compared to the NCHS reference [national: 29.1 (95 % CI 25.9, 32.2) and Thatta: 44.8 (95 % CI 41.1, 48.5), respectively]. It also gave significantly higher prevalence of wasting for the Thatta survey [22.9 (95 % CI 20.3, 25.5)] compared to the NCHS reference [15.7 (95 % CI 13.5, 17.8)]. Differences due to choice of standard were pronounced during infancy and for severely wasted and severely stunted children. CONCLUSIONS: Pakistan should switch to the robustly constructed and up-to-date WHO growth standard for assessing under-nutrition. New growth charts should be introduced along with training of health workers. This has implications for nutritional intervention programmes, for resetting the country's targets for Millennium Development Goal 1 and for monitoring nutritional trends.

Graduate public health education--Singapore's contribution to strengthening capacity in the region and beyond.

The year 2008 marks the 55th anniversary of the graduate public health programme in Singapore. This article traces the evolution of the programme-from the Diploma in Public Health in 1953 to the Master of Public Health in 2007--in response to changing challenges and needs. It also discusses the role Singapore can continue to play in addressing global inequities in access to public health education and in strengthening public health capacity in the region and beyond.

Professional satisfaction among Singapore physicians.

OBJECTIVE: This paper reports on a questionnaire survey among Singapore physicians, carried out from November, 2003 to January, 2004 to gauge their professional satisfaction levels. METHODS: The survey participants (N=380) were drawn randomly from both public and private sectors and comprised both general practitioners (GPs) and specialists. Multivariate analysis identified the predictive factors leading to positive or negative responses on selected items. Findings were compared with similar studies in other countries and possible reasons for differences obtained are offered. RESULTS: Our findings indicate the majority of physicians in Singapore are quite satisfied with their autonomy to treat patients (92%) and their relationship with patients (94%), but rather dissatisfied with the amount of leisure time they have (48%) and promotion and career development prospects (38%). Compared to specialists, GPs are more likely to be satisfied with amount of time for each patient (82%), ability to initiate changes in the way work is done in medical practice (73%), and harmony of relationship among colleagues and staff associates (80%). CONCLUSIONS: To the best of the authors' knowledge, this study is the first attempt to measure physicians' view on professional satisfaction in Singapore. It could serve as a benchmark which is very useful for policy makers, hospital administrators to better manage physicians.

Public trust in primary care doctors, the medical profession and the healthcare system among Redhill residents in Singapore.

INTRODUCTION: There have been few studies on public trust in doctors and healthcare systems and this is the first in Singapore. MATERIALS AND METHODS: A cross-sectional survey was carried out in Redhill in January 2005. Citizens or Permanent Residents aged > or =18 years were randomly selected, one per household to avoid cluster bias, and 361 participated (response rate 68.7%). An interview administered questionnaire included 3 questionnaires measuring public trust: "Interpersonal Trust in Physicians Scale" for primary care doctors; "Trust in Physicians Generally Scale" for the medical profession; and "Trust in Healthcare System Scale" for the Healthcare System. Questions were answered on a Likert scale: 1. Strongly Disagree, 2. Disagree, 3. Neutral, 4. Agree, 5. Strongly Agree. Individual transformed scores of trust (range, 0 to 100) were equally divided into 5 categories with their average being the transformed mean. RESULTS: Trust in primary care doctors (mean 59.7) had proportions (prevalence rates) of: very low 0.3%, low 2.5%, neutral 40.4%, high 54.0%, and very high 2.8%. Trust in the medical profession (mean 61.8) had proportions of: very low 1.0%, low 7.7%, neutral 33.7%, high 47.0%, and very high 10.5%. Trust in the healthcare system (mean 61.5) had proportions of: very low 0.5%, low 4.1%, neutral 40.0%, high 48.7%, and very high 6.7%. For areas of the healthcare system, proportions of high/very high trust were: "Healthcare Providers' Expertise" (70.8%), "Quality of Care" (61.5%), "Patient Focus of Providers" (58.7%), "Information Supply and Communication by Care Providers" (52.3%), "Quality of Cooperation" (43.3%), and Policies of the Healthcare System" (24.6%). CONCLUSIONS: While low proportions had low/very low trust, the high proportions with neutral trust and the rather low level of trust in "Policies of the Healthcare System" are causes for concern.

Predictors of vancomycin-resistant enterococcus (VRE) carriage in the first major VRE outbreak in Singapore.

INTRODUCTION: Until recently, vancomycin-resistant enterococcus (VRE) infection or colonisation was a rare occurrence in Singapore. The first major VRE outbreak involving a 1500-bed tertiary care institution in March 2005 presented major challenges in infection control and came at high costs. This study evaluates the predictors of VRE carriage based on patients' clinical and demographic profiles. MATERIALS AND METHODS: Study patients were selected from the hospital inpatient census population during the VRE outbreak (aged 16 years or more). Clinical information from 84 cases and 377 controls were analysed. RESULTS: Significant predictors of VRE carriage included: age>65 years Odds ratio (OR), 1.98; 95% CI (confidence interval), 1.14 to 3.43); female gender (OR, 2.15; 95% CI, 1.27 to 3.65); history of diabetes mellitus (OR, 1.94; 95% CI, 1.14 to 3.30), and staying in a crowded communal ward (OR, 2.75; 95% CI, 1.60 to 4.74). Each additional day of recent hospital stay also posed increased risk (OR, 1.03; 95% CI, 1.01 to 1.04). CONCLUSION: Elderly diabetic females with prolonged hospitalisation in crowded communal wards formed the profile that significantly predicted VRE carriage in this major hospital-wide outbreak of VRE in Singapore. It is imperative that active VRE surveillance and appropriate infection control measures be maintained in these wards to prevent future VRE outbreaks.

High coverage of influenza vaccination among healthcare workers can be achieved during heightened awareness of impending threat.

INTRODUCTION: As preparation against a possible avian flu pandemic, international and local health authorities have recommended seasonal influenza vaccination for all healthcare workers at geographical risk. This strategy not only reduces "background noise", but also chance of genetic shifts in avian influenza viruses when co-infection occurs. We evaluate the response of healthcare workers, stratified by professional groups, to a non-compulsory annual vaccination call, and make international comparisons with countries not at geographical risk. MATERIALS AND METHODS: A cross-sectional study was performed over the window period for vaccination for the 2004 to 2005 influenza season (northern hemisphere winter). The study population included all adult healthcare workers (aged < or =21 years) employed by a large acute care tertiary hospital. RESULTS: The uptake rates among frontline caregivers--doctors >50%, nurses >65% and ancillary staff >70%--markedly exceeded many of our international counterparts results. CONCLUSION: Given its close proximity in time and space to the avian flu pandemic threat, Singapore healthcare workers responded seriously and positively to calls for preventive measures. Other factors, such as the removal of financial, physical and mental barriers, may have played important facilitative roles as well.

Factors predicting nurses' consideration of leaving their job during the SARS outbreak.

Taiwan was affected by an outbreak of severe acute respiratory syndrome (SARS) in early 2003. A questionnaire survey was conducted to determine (1) the perceptions of risk of SARS infection in nurses; (2) the proportion of nurses considering leaving their job; and (3) work as well as non-work factors related to nurses' consideration of leaving their job because of the SARS outbreak. Nearly three quarters (71.9%) of the participants believed they were 'at great risk of exposure to SARS', 49.9% felt 'an increase in workload', and 32.4% thought that people avoided them because of their job; 7.6% of the nurses not only considered that they should not care for SARS patients but were looking for another job or considering resignation. The main predictors of nurses' consideration of leaving their job were shorter tenure, increased work stress, perceived risk of fatality from SARS, and affected social relationships. The findings are important in view of potential impending threats of pandemics such as avian influenza.

Global response to pandemic flu: more research needed on a critical front.

If and when sustained human-to-human transmission of H5N1 becomes a reality, the world will no longer be dealing with sporadic avian flu borne along migratory flight paths of birds, but aviation flu - winged at subsonic speed along commercial air conduits to every corner of planet Earth. Given that air transportation is the one feature that most differentiates present day transmission scenarios from those in 1918, our present inability to prevent spread of influenza by international air travel, as reckoned by the World Health Organization, constitutes a major weakness in the current global preparedness plan against pandemic flu. Despite the lessons of SARS, it is surprising that aviation-related health policy options have not been more rigorously evaluated, or scientific research aimed at strengthening public health measures on the air transportation front, more energetically pursued.

Black or white cat? Ideology meets reality in healthcare finance and provision.

Despite the intense debates over state or private sector dominance in healthcare finance and provision, there are no clear winners. Failed models exist on either end of the ideological spectrum and no country in the world has one that is purely public or purely private. Neither does a perfect public-private mix exist; all solutions are, at best, partial. The important questions are whether or not the political choices made are affordable, sustainable and equitable. When ideology meets reality, it boils down to what trade-offs different societies at different stages of economic development are willing to make.

Risk perception and impact of Severe Acute Respiratory Syndrome (SARS) on work and personal lives of healthcare workers in Singapore: what can we learn?

INTRODUCTION: Healthcare workers (HCWs) were at the frontline during the battle against Severe Acute Respiratory Syndrome (SARS). Understanding their fears and anxieties may hold lessons for handling future outbreaks, including acts of bioterrorism. METHOD: We measured risk perception and impact on personal and work life of 15,025 HCWs from 9 major healthcare institutions during the SARS epidemic in Singapore using a self-administered questionnaire and Impact of Events Scale and analyzed the results with bivariate and multivariate statistics. RESULTS: From 10,511 valid questionnaires (70% response), we found that although the majority (76%) perceived a great personal risk of falling ill with SARS, they (69.5%) also accepted the risk as part of their job. Clinical staff (doctors and nurses), staff in daily contact with SARS patients, and staff from SARS-affected institutions expressed significantly higher levels of anxiety. More than half reported increased work stress (56%) and work load (53%). Many experienced social stigmatization (49%) and ostracism by family members (31%), but most (77%) felt appreciated by society. Most felt that the personal protective measures implemented were effective (96%) and that the institutional policies and protocols were clear (93%) and timely (90%). CONCLUSION: During epidemics, healthcare institutions have a duty to protect HCWs and help them cope with their personal fears and the very stressful work situation. Singapore's experience shows that simple protective measures based on sound epidemiological principles, when implemented in a timely manner, go a long way to reassure HCWs.

SARS risk perceptions in healthcare workers, Japan.

In coping with severe acute respiratory syndrome (SARS), infection control measures are a key aspect of protecting healthcare workers. We conducted a survey concerning perception of risk and countermeasures for SARS in 7 tertiary hospitals in Japan from July through September 2003, immediately after the SARS epidemic in neighboring countries. Based on 7,282 respondents out of 9,978 questionnaires administered, we found the perception of risk to be relatively high and the perception of countermeasures at the institutional level to be relatively low. Knowledge of preventive measures, concept of (opinions regarding) institutional measures, and perception of risk differed substantially among the 3 job categories, notably between physicians and nurses. The concept of institutional measures was the most important predictor of individual perception of risk. In view of the potential for future epidemics, planning and implementing institutional measures should be given a high priority.

Public perceptions of private health care in socialist China.

We present the findings of a United Nations Development Programme-World Health Organization study commissioned by China's Ministry of Health on use of public and private ambulatory care services in three Chinese provinces. We found much unmet medical need (16 percent), attributed mainly to the perceived high cost of care. Seventy-one percent had no health insurance (90 percent in rural and 51 percent in urban areas). For 33 percent, the last consultation was with a private practitioner. Widespread dissatisfaction with public providers (mainly high user fees and poor staff attitudes) is driving patients to seek cheaper but lower-quality care from poorly regulated private providers.

Shifting the burden of health care finance: a case study of public-private partnership in Singapore.

Since becoming independent in 1965, Singapore has attained high standards in health care provision while successfully transferring a substantial portion of the health care burden to the private sector. The government's share of total health care expenditure contracted from 50% in 1965 to 25% in 2000. At first glance, the efficiency-driven health care financing reforms which emphasize individual over state responsibility appear to have been implemented at the expense of equity. On closer examination, however, Singaporeans themselves seem unconcerned about any perceived inequity of the system. Indeed, they appear content to pay part of their medical expenses, plus additional monies if they demand a higher level of services. In fact, access to needed care for the poor is explicitly guaranteed. Mechanisms also exist to protect against financial impoverishment resulting from catastrophic illness. Singapore's experience provides an interesting case study in public-private partnership, illustrating how a hard-headed approach to health policy can achieve national health goals while balancing efficiency and equity concerns.
