Constraints and barriers to public health adaptation to climate change: a review of the literature.

Public health adaptation to climate change is an important issue and inevitably is needed to address the adverse health impacts of climate change over the next few decades. This paper provides an overview of the constraints and barriers to public health adaptation and explores future research directions in this emerging field. An extensive literature review was conducted in 2010 and published literature from 2000 to 2010 was retrieved. This review shows that public health adaptation essentially can operate at two levels, namely, adaptive-capacity building and implementation of adaptation actions. However, there are constraints and barriers to public health adaptation arising from uncertainties of future climate and socioeconomic conditions, as well as financial, technologic, institutional, social capital, and individual cognitive limits. The opportunities for planning and implementing public health adaptation are reliant on effective strategies to overcome these constraints and barriers. It is proposed here that high research priority should be given to multidisciplinary research on the assessment of potential health impacts of climate change, projections of health impacts under different climate and socioeconomic scenarios, identification of health co-benefits of mitigation strategies, and evaluation of cost-effective public health adaptation options.

The nursing profession in Saudi Arabia: an overview.

AIM The study aims to provide an overview of the nursing profession in Saudi Arabia, including its history, educational development, workforce and professional practice. BACKGROUND Saudi Arabia is faced with a chronic shortage of Saudi nurses, accompanied by high rates of turnover. Expatriate nurses form a large proportion of the nursing workforce in Saudi healthcare facilities, with Saudis comprising only 29.1% of the total nursing workforce. Despite the fact that the proportion of Saudi nurses is very low in general, this rate is lower in the private health sector where local nurses comprise only 4.1% of the total. METHODS Data relating to the nursing profession in Saudi Arabia were extracted from published literature identified through search of a range of publically available databases such as Medline, CINAHL, Google Scholar, Saudi health databases, Saudi health journals, government reports and relevant texts. Obtained information was evaluated for relevance and grouped on a thematic basis. CONCLUSION The status of nursing in Saudi Arabia should be enhanced in order to make it a worthwhile career. The media should engage in helping to promote a positive image of the nursing profession. The education sector should reconsider the length of nursing training (5 years compared with 3 years in many developed countries) while maintaining competent and safe practice. Reducing the financial burden on the nursing student through provision of additional financial support would encourage more students. In particular, nurses should be paid a full salary during the intern year as currently occurs with medical students.ALMALKI M., FITZGERALD G. & CLARK M.

The impact of heatwaves on mortality and emergency hospital admissions from non-external causes in Brisbane, Australia

Objectives Heatwaves can have significant health consequences resulting in increased mortality and morbidity. However, their impact on people living in tropical/subtropical regions remains largely unknown. This study assessed the impact of heatwaves on mortality and emergency hospital admissions (EHAs) from non-external causes (NEC) in Brisbane, a subtropical city in Australia. Methods We acquired daily data on weather, air pollution and EHAs for patients aged 15 years and over in Brisbane between January 1996 and December 2005, and on mortality between January 1996 and November 2004. A locally derived definition of heatwave (daily maximum ≥37°C for 2 or more consecutive days) was adopted. Case–crossover analyses were used to assess the impact of heatwaves on cause-specific mortality and EHAs. Results During heatwaves, there was a statistically significant increase in NEC mortality (OR 1.46; 95% CI 1.21 to 1.77), cardiovascular mortality (OR 1.89; 95% CI 1.44 to 2.48), diabetes mortality in those aged 75+ (OR 9.96; 95% CI 1.02 to 96.85), NEC EHAs (OR 1.15; 95% CI 1.07 to 1.23) and EHAs from renal diseases (OR 1.41; 95% CI 1.09 to 1.83). The elderly were found to be particularly vulnerable to heatwaves (eg, for NEC EHAs, OR 1.24 for 65–74-year-olds and 1.39 for those aged 75+). Conclusions Significant increases in NEC mortality and EHAs were observed during heatwaves in Brisbane where people are well accustomed to hot summer weather. The most vulnerable were the elderly and people with cardiovascular, renal or diabetic disease.

The relationship between quality of work life and turnover intention of primary health care nurses in Saudi Arabia

BackgroundQuality of work life (QWL) has been found to influence the commitment of health professionals, including nurses. However, reliable information on QWL and turnover intention of primary health care (PHC) nurses is limited. The aim of this study was to examine the relationship between QWL and turnover intention of PHC nurses in Saudi Arabia.MethodsA cross-sectional survey was used in this study. Data were collected using Brooks’ survey of Quality of Nursing Work Life, the Anticipated Turnover Scale and demographic data questions. A total of 508 PHC nurses in the Jazan Region, Saudi Arabia, completed the questionnaire (RR = 87%). Descriptive statistics, t-test, ANOVA, General Linear Model (GLM) univariate analysis, standard multiple regression, and hierarchical multiple regression were applied for analysis using SPSS v17 for Windows.ResultsFindings suggested that the respondents were dissatisfied with their work life, with almost 40% indicating a turnover intention from their current PHC centres. Turnover intention was significantly related to QWL. Using standard multiple regression, 26% of the variance in turnover intention was explained by QWL, p < 0.001, with R2 = .263. Further analysis using hierarchical multiple regression found that the total variance explained by the model as a whole (demographics and QWL) was 32.1%, p < 0.001. QWL explained an additional 19% of the variance in turnover intention, after controlling for demographic variables.ConclusionsCreating and maintaining a healthy work life for PHC nurses is very important to improve their work satisfaction, reduce turnover, enhance productivity and improve nursing care outcomes.

Objective:  Flood is the most common natural disaster in Australia and causes more loss of life than any other disaster. This article describes the incidence and causes of deaths directly associated with floods in contemporary Australia.

Older people's use of ambulance services: a population based analysis.

OBJECTIVE: To investigate the use of emergency and non-urgent ambulance transport services by people aged 65 years and over. SETTING: The study was undertaken in Queensland where the Queensland Ambulance Services (QAS) is the sole provider of emergency pre-hospital and non-urgent ambulance services for the entire state. METHODS: The age and sex of 351,000 emergency and non-urgent cases treated and transported by the QAS from July 1995 to June 1996 were analysed. RESULTS: People aged 65 years and over who comprise 12% of the population utilise approximately one third of the emergency and two thirds of the non-urgent ambulance resources provided in Queensland. While the absolute number of occasions of service for females for emergency services is higher than for males, when the data are stratified for age and sex, males have higher rates of emergency ambulance service utilisation than females across every age group, and particularly in older age groups. Gender differences are also found for non-urgent ambulance usage. The absolute number of occasions of service for older females aged 65 and over using non-urgent ambulance transport is high, but utilisation patterns on stratified data reveal similar gender usage patterns across most age groupings, except at the older age groupings where male usage greatly exceeds female usage. CONCLUSIONS: As the aged are disproportionately high users of ambulance services, it will become increasingly important for ambulance services to plan for the projected increase in the aged population. Emergency pre-hospital care is one of the few health services along the continuum of care where male usage patterns are higher than those of females. More information needs to be obtained on the age and presenting characteristics of those people who are multiple users of the ambulance service. Such information will assist service planners.

Quality of work life among primary health care nurses in the Jazan region, Saudi Arabia: a cross-sectional study

BackgroundQuality of work life (QWL) is defined as the extent to which an employee is satisfied with personal and working needs through participating in the workplace while achieving the goals of the organization. QWL has been found to influence the commitment and productivity of employees in health care organizations, as well as in other industries. However, reliable information on the QWL of primary health care (PHC) nurses is limited. The purpose of this study was to assess the QWL among PHC nurses in the Jazan region, Saudi Arabia.MethodsA descriptive research design, namely a cross-sectional survey, was used in this study. Data were collected using Brooks’ survey of quality of nursing work life and demographic questions. A convenience sample was recruited from 134 PHC centres in Jazan, Saudi Arabia. The Jazan region is located in the southern part of Saudi Arabia. A response rate of 91% (n = 532/585) was achieved (effective response rate = 87%, n = 508). Data analysis consisted of descriptive statistics, t-test and one way-analysis of variance. Total scores and subscores for QWL items and item summary statistics were computed and reported using SPSS version 17 for Windows.ResultsFindings suggested that the respondents were dissatisfied with their work life. The major influencing factors were unsuitable working hours, lack of facilities for nurses, inability to balance work with family needs, inadequacy of vacations time for nurses and their families, poor staffing, management and supervision practices, lack of professional development opportunities, and an inappropriate working environment in terms of the level of security, patient care supplies and equipment, and recreation facilities (break-area). Other essential factors include the community’s view of nursing and an inadequate salary. More positively, the majority of nurses were satisfied with their co-workers, satisfied to be nurses and had a sense of belonging in their workplaces. Significant differences were found according to gender, age, marital status, dependent children, dependent adults, nationality, nursing tenure, organizational tenure, positional tenure, and payment per month. No significant differences were found according to education level of PHC nurses and location of PHC.ConclusionsThese findings can be used by PHC managers and policy makers for developing and appropriately implementing successful plans to improve the QWL. This will help to enhance the home and work environments, improve individual and organization performance and increase the commitment of nurses.

Demand for public hospital emergency department services in Australia: 2000–2001 to 2009–2010

Objective: Hospital EDs are a significant and high‐profile component of Australias health‐care system, which in recent years have experienced considerable crowding. This crowding is caused by the combination of increasing demand, throughput and output factors. The aim of the present article is to clarify trends in the use of public ED services across Australia with a view to providing an evidence basis for future policy analysis and discussion.

Development of health risk-based metrics for defining a heatwave: a time series study in Brisbane, Australia

BackgroundThis study attempted to develop health risk-based metrics for defining a heatwave in Brisbane, Australia.MethodsPoisson generalised additive model was performed to assess the impact of heatwaves on mortality and emergency hospital admissions (EHAs) in Brisbane.ResultsIn general, the higher the intensity and the longer the duration of a heatwave, the greater the health impacts. There was no apparent difference in EHAs risk during different periods of a warm season. However, there was a greater risk for mortality in the 2nd half of a warm season than that in the 1st half. While elderly (≥75 years) were particularly vulnerable to both the EHA and mortality effects of a heatwave, the risk for EHAs also significantly increased for two other age groups (0 – 64 years and 65 – 74 years) during severe heatwaves. Different patterns between cardiorespiratory mortality and EHAs were observed. Based on these findings, we propose the use of a tiered heat warning system based on the health risk of heatwave.ConclusionsHealth risk-based metrics are a useful tool for the development of local heatwave definitions. This tool may have significant implications for the assessment of heatwave-related health consequences and development of heatwave response plans and implementation strategies.

Exploration of the health risk-based definition for heatwave: A multi-city study.

BACKGROUND As heatwaves are expected to be more frequent, longer, and more intense in the future, it is imperative to understand how heatwaves affect health. However, it is intensely debated about how a heatwave should be defined. OBJECTIVES This study explored the possibility of developing a health risk-based definition for heatwave, and assessed the heat-related mortality in the three largest Australian cities. METHODS Daily data on climatic variables and non-accidental deaths for Brisbane, Melbourne and Sydney during the period 1988-2009 were obtained from relevant government agencies. Several local heatwave definitions were tested by using percentiles (e.g., from the 75th to 99th centile) of mean temperature with duration ≥2 days across these cities. We examined the relative risks of mortality associated with heatwaves in each city using Poisson generalised additive model, after controlling for long-term trend, within-season variation, day of the week, and relative humidity. Then, Bayesian hierarchical model with segment-spline was used to examine the threshold for the heatwave-related impacts. RESULTS A consistent and significant increase in mortality during heatwaves was observed in all three cities. The pooled data show that the relative risk of mortality started to increase around the 95th centile of temperature, increased sharply at the 97th centile and rose alarmingly at the 99th centile. Based on research findings, we proposed tiered health risk-based metrics to define a heatwave. CONCLUSIONS Our findings provide supportive evidence for developing health risk-based metrics to assess the impacts of heatwave. These findings may have important implications for assessing and reducing the burden of heat-related mortality.
