Health care facility vulnerability in developing nations: strengthening health care policy-making and implementation

Background

In developing countries such as India, inadequate importance and consideration given to assessment of health care facilities negatively affects progress towards achieving health targets. India has focused on developing Primary Health Centres (PHCs) for rural basic laboratory and curative services. The local decision-makers do not have any national-level framework to evaluate the vulnerability of PHCs which are not meeting national PHC standards, nor do they have resources to meet national PHC standards.

Aim

The study proposed a framework to assess the public health care facilities for vulnerability.

Methods

A cross-sectional questionnaire survey was performed. The study used PHC laboratory services of 42 PHCs of Osmanabad District, India as a case study for proposed framework. The data assessment was carried out at district level, block level, PHC cluster level, and PHC level to provide flexibility to local decision-makers in taking remedial measures.

Results

Staff workload (73.17%), physician’s need (51.22%), and organization structure (36.59%) are the most prevalent challenges across PHCs. Multiple challenges are prevalent in the PHCs across districts. The PHCs with poor medical doctor (MD) capability or many challenges have shown poor laboratory performance.

Conclusion

Governance need to be strengthened in PHCs, followed by sustained support in resources and financing. Poor health status in developing nations necessitates a public health response based on health systems. Therefore, an assessment of health facility vulnerability in the form of laboratory services is essential in primary health care facilities.

     

Age and IQ Explained Working Memory Performance in a RCT with Fatty Fish in a Group of Forensic Inpatients

Objectives

To investigate the effect of a long-term fatty fish intervention on a pure cognitive mechanism important for self-regulation and mental health, i.e. working memory (WM), controlling for age and IQ.

Design

A randomized controlled trial.

Setting

A forensic facility.

Participants

Eighty-four young to middle aged male forensic inpatients with psychiatric disorders.

Intervention

Consumption of farmed salmon or control meal (meat) three times a week during 23 weeks.

Measurement

Performance on WM tasks, both accuracy and mean reaction time, were recorded pre and post intervention.

Results

Performance on a cognitive functioning tasks taxing WM seemed to be explained by age and IQ.

Conclusion

Fatty fish consumption did not improve WM performance in a group of young to middle aged adults with mental health problems, as less impressionable factors such as aging and intelligence seemed to be the key components. The present study improves the knowledge concerning the interaction among nutrition, health and the aging process.

     

A cross-sectional assessment of primary healthcare facilities for provision of antenatal care: calling for improvements in Basic Health Units in Punjab,Pakistan

Background

There are two types of barriers to the utilisation of maternal health and antenatal care (ANC) services, including the supply-side barriers operating at the health facility level and demand-side, affecting the utilisation ANC services by pregnant women. The purpose of the study was to assess the essential resources required for the provision of ANC services in primary healthcare facilities in Punjab, Pakistan.

Methods

A cross-sectional facility assessment was conducted in primary healthcare facilities across Punjab. A multi-stage sampling was used to randomly select nine districts from three stratifications and 19 primary healthcare facilities in the public sector (17 Basic Health Units (BHUs) and two Rural Health Centres (RHCs)) from each district. A total of 171 health facilities were included. Data on infrastructure and availability of equipment, essential supplies, medicines, treatment protocols, and infection control items was collected through pre-tested, semi-structured questionnaires. Univariate analysis was carried out to describe the frequency and percentages of facilities across three ratings (good, average, and poor) by type of facility.

Results

Overall, 28% of facilities had poor infrastructure and the availability of equipment was poor in 16% of the health facilities. Essential supply items, such as urine strips for albumin, blood sugar testing strips, and haemoglobin reagents, were particularly poorly stocked. However, infrastructure and the availability of equipment and supplies were generally better in RHCs compared to BHUs.

Conclusion

Health facilities lacked the resources required to provide quality ANC services, particularly in terms of infrastructure, equipment, supply items, and medicines. The availability of these resources needs to be urgently addressed.

     

Can contracted out health facilities improve access,equity, and quality of maternal and newborn health services? Evidence from Pakistan

Background

The case of contracting out government health services to non-governmental organizations (NGOs) has been weak for maternal, newborn, and child health (MNCH) services, with documented gains being mainly in curative services. We present an in-depth assessment of the comparative advantages of contracting out on MNCH access, quality, and equity, using a case study from Pakistan.

Methods

An end-line, cross-sectional assessment was conducted of government facilities contracted out to a large national NGO and government-managed centres serving as controls, in two remote rural districts of Pakistan. Contracting out was specific for augmenting MNCH services but without contractual performance incentives. A household survey, a health facility survey, and focus group discussions with client and spouses were used for assessment.

Results

Contracted out facilities had a significantly higher utilization as compared to control facilities for antenatal care, delivery, postnatal care, emergency obstetric care, and neonatal illness. Contracted facilities had comparatively better quality of MNCH services but not in all aspects. Better household practices were also seen in the district where contracting involved administrative control over outreach programs. Contracting was also faced with certain drawbacks. Facility utilization was inequitably higher amongst more educated and affluent clients. Contracted out catchments had higher out-of-pocket expenses on MNCH services, driven by steeper transport costs and user charges for additional diagnostics. Contracting out did not influence higher MNCH service coverage rates across the catchment. Physical distances, inadequate transport, and low demand for facility-based care in non-emergency settings were key client-reported barriers.

Conclusion

Contracting out MNCH services at government health facilities can improve facility utilization and bring some improvement in  quality of services. However, contracting out of health facilities is insufficient to increase service access across the catchment in remote rural contexts and requires accompanying measures for demand enhancement, transportation access, and targeting of the more disadvantaged clientele.

     

Quality of Life and Mental Health in Older Adults with Obesity and Frailty: Associations with a Weight Loss Intervention

Objective

To examine the bi-directional associations of a weight loss intervention with quality of life and mental health in obese older adults with functional limitations.

Design

Combined-group analyses of secondary variables from the MEASUR-UP randomized controlled trial.

Setting

Academic medical center.

Participants

Obese community-dwelling men and women (N = 67; age ≥60; BMI ≥30) with functional limitations (Short Physical Performance Battery [SPPB] score of 4–10 out of 12).

Intervention

Six-month reduced calorie diet at two protein levels.

Measurements

Weight, height, body composition, physical function, medical history, and mental health and quality of life assessments (Center for Epidemiologic Studies Depression Scale [CES-D]; Profile of Mood States [POMS], Pittsburgh Sleep Quality Index [PSQI]; Perceived Stress Scale [PSS]; Satisfaction with Life Scale [SWLS]; and Short Form Health Survey [SF-36]) were acquired at 0, 3 and 6 months.

Results

Physical composite quality of life (SF-36) improved significantly at 3 months (β = 6.29, t2,48 = 2.60, p = 0.012) and 6 months (β = 10.03, t2,48 = 4.83, p < 0.001), as did several domains of physical quality of life. Baseline depression symptoms (CES-D and POMS) were found to predict lower amounts of weight loss; higher baseline sleep latency (PSQI) and anger (POMS) predicted less improvement in physical function (SPPB).

Conclusion

The significant bi-directional associations found between a weight loss intervention and mental health/quality of life, including substantial improvements in physical quality of life with obesity treatment, indicate the importance of considering mental health and quality of life as part of any weight loss intervention for older adults.

     

Access to comprehensive emergency obstetric and newborn care facilities in three rural districts of Sindh province,Pakistan

Background

Pakistan’s maternal and child health indicators remain unacceptably high, with a maternal mortality ratio of 276 per 100,000 live births and a neonatal mortality rate of 55 per 1,000 live births. Provision of basic and comprehensive emergency obstetric and newborn care is mandated by the government; however, coverage, access, and utilisation levels remain unsatisfactory, with the situation in Sindh province being amongst the worst in the country. This study attempted to assess access to comprehensive emergency obstetric and newborn care (C-EmONC) facilities and barriers hampering access in Sindh.

Methods

One public sector hospital in each of three districts in Sindh province providing C-EmONC services were selected for a facility exit survey. A cross-sectional household survey and focus group discussions were conducted in the catchment population of these hospitals.

Results

Overall, 82% and 96% of those who utilised a public or private C-EmONC facility, respectively, incurred out-of-pocket expenditure. As expected, those living more than 5 km from the facility reported higher mean expenditure than those living within 5 km of the facility. More than half of the respondents (55%) among public sector users and the majority (71%) of private sector users could not afford travel costs. More than one third (35%) of public sector users and about two thirds (64%) of private sector users who could not afford travel costs took loans. The proportion of respondents who took loans was higher among those living more than 5 km of the health facility compared to those living within a 5 km distance. The majority of respondents (70%) in the community survey chose to go to a private sector C-EmONC facility. In addition to poverty, in terms of sociocultural access, religious and ethnic discrimination and the poor attitude of facility staff were amongst the most important barriers to accessing a C-EmONC facility.

Conclusions

C-EmONC facilities in both the public and private sectors may simply not be accessible and affordable for the vast majority of poor and marginalised women in targeted districts.

     

Accelerometer assessment of physical activity and its association with physical function in older adults residing at assisted care facilities

Objectives

To describe levels of physical activity among older adults residing at assisted care facilities and their association with physical function.

Design

Cross-sectional analysis.

Setting

Assisted care facilities within the greater Boston, MA area.

Participants

Older adults aged 65 years and older (N = 65).

Measurements

Physical Activity Level (PAL) as defined by quartiles from accelerometry (counts and steps), Short Physical Performance Battery (SPPB) Score, gait speed, and handgrip strength.

Results

Participants in the most active accelerometry quartile engaged in 25 minutes/week of moderate to vigorous physical activity (MVPA) and walked 2,150 steps/day. These individuals had an SPPB score, 400 meter walk speed, and handgrip strength that was 3.7–3.9 points, 0.3–0.4 meters/second, and 4.5–5.1 kg greater respectively, than individuals in the lowest activity quartile, who engaged in less than 5 min/wk of MVPA or took fewer than 460 steps/day.

Conclusion

Despite engaging in physical activity levels far below current recommendations (150 min/week of MVPA or > 7000 steps/day), the most active older adults in this study exhibited clinically significant differences in physical function relative to their less active peers. While the direction of causality cannot be determined from this cross-sectional study, these findings suggest a strong association between PAL and physical function among older adults residing in an assisted care facility.

     

The role of supportive supervision using mobile technology in monitoring and guiding program performance: a case study in Nigeria, 2015–2016

Background

Supportive supervision is one of the interventions that fosters program improvement by way of imparting knowledge and skills to health workers. The basic challenge in supportive supervision is the availability of data in real time for timely and effective feedback. Thus, the main objective of this study was to determine the contribution of real-time data collection during supportive supervision for timely feedback and generation of evidence for health intervention planning.

Methods

We analyzed supportive supervision records collected through handheld devices employing the open data kit (ODK) platform from July 2015 to June 2016. Supervision was conducted across the country by 592 World Health Organization (WHO) officers. The availability of real-time data and the distance of health facilities to the community were analyzed.

Results

During the study period, 90,396 health facilities were supervised. The average time spent during supervision varied from 1.53 to 3.78 h across the six geopolitical zones of the country. The average interval between completion of the supervisory checklist and synchronization with the server varied from 3.9 h to 7.5 h. The average distance between the health facility and a ward varied from 5 to 24 km.

Conclusion

The use of handheld devices for supportive supervision provided real-time data from health facilities to state and zonal levels for analysis and feedback. Program officers used the findings to rectify process indicators in time for a better outcome.

     

Bypassing health facilities in rural Mozambique: spatial,institutional, and individual determinants

Background

Access to sexual and reproductive health (SRH) services is critical for such outcomes as pregnancy and birth, prenatal and neonatal mortality, maternal morbidity and mortality, and prevention of vertical transmission of infections like HIV. Health facilities are typically set up where they can efficiently serve the nearby targeted population. However, the actual utilization of health care can be complicated as people sometimes bypass the closest or nearby facilities for various reasons such as service quality. A better understanding of how people actually utilize health services can benefit future health resource allocation as well as health program planning.

Methods

In this study, we use prenatal care as an example of a basic, widely available service to investigate women’s choice and bypassing of SRH facilities as well as potential influencing factors at the geographic, clinic, household, and individual levels. The data come from a population-based survey of women of reproductive age in rural Mozambique. The spatial pattern of utilization of health clinics for prenatal care is explored by geographical information system (GIS)-based spatial analysis. Logistic regression is fitted to test the hypotheses regarding the effect of distance, service quality, and household/individual-level factors on the bypassing of the nearest clinic.

Results

The results indicate that most women living near clinics tend to utilize the closest facilities for prenatal care and those who travel farther mainly do so to seek better services. Further, for women who live far from a clinic (>?5.5?km), service quality still plays an important role in the facility bypassing while the effect of distance is no longer significant. The bypassing of nearest facility is also affected by individual characteristics such as age, HIV status, and household economic conditions.

Conclusions

The findings help to better understand health facility choice and bypassing in developing settings, in general, and in resource-limited Sub-Saharan settings, in particular. They offer valuable guidance for future health resource allocation and health service planning.

     

An Examination of Care Practices of Pregnant Women Incarcerated in Jail Facilities in the United States

Objective

The number of incarcerated women in the United States has been steadily increasing over the last 30 years. An estimated 6–10% of these women are pregnant at intake. Previous studies on the health needs and care of pregnant incarcerated women have focused mainly on prison settings. Therefore, we examined the pregnancy-related accommodations and health care provided for regional jail populations.

Method

The present study is a quantitative survey (administered through phone or email to employees of predominately jail medical facilities) of common practices and policies employed across 53 jail facilities in the United States as a function of geographic region (North vs. South; West vs. Central vs. East). We examined provision of pregnancy screening, special diets, and drug rehabilitation and prohibition of shackling.

Results

Strikingly, across all aspects of the care of pregnant incarcerated women there are areas to be improved upon. Notably, only 37.7% of facilities pregnancy test all women upon entry, 45.7% put opioid addicted women through withdrawal protocol, and 56.7% of facilities use restraints on women hours after having a baby.

Conclusion

In this first study to examine practices in regional jails nationwide, we found evidence that standards of care guidelines to improve health and well-being of pregnant incarcerated women, set by agencies such as American College of Obstetricians and Gynecologists, are not being followed in many facilities. Because not following these guidelines could pose major health risks to the mother and developing fetus, better policies, better enforcement of policies, and better common practices are needed to improve the health and welfare of pregnant incarcerated women.

     

Psychosocial risk factors for obesity among women in a family planning clinic

Background

The epidemiology of obesity in primary care populations has not been thoroughly explored. This study contributes to filling this gap by investigating the relationship between obesity and different sources of personal stress, mental health, exercise, and demographic characteristics.

Methods

A cross-sectional survey using a convenience sample. Five hundred women who attended family planning clinics were surveyed and 274 provided completed answers to all of the questions analyzed in this study. Exercise, self-rated mental health, stress, social support, and demographic variables were included in the survey. Multiple logistic regression analysis was performed.

Results

After adjusting for mental health, exercise, and demographic characteristics of subjects, analysis of the data indicated that that being having a large family and receiving no support from parents were related to obesity in this relatively young low-income primary care sample, but self-reported stress and most types of social support were not significant.

Conclusion

Obesity control programs in primary care centers directed at low-income women should target women who have large families and who are not receiving support from their parents.

     

Geographically linking population and facility surveys: methodological considerations

Background

The relationship between health services and population outcomes is an important area of public health research that requires bringing together data on outcomes and the relevant service environment. Linking independent, existing datasets geographically is potentially an efficient approach; however, it raises a number of methodological issues which have not been extensively explored. This sensitivity analysis explores the potential misclassification error introduced when a sample rather than a census of health facilities is used and when household survey clusters are geographically displaced for confidentiality.

Methods

Using the 2007 Rwanda Service Provision Assessment (RSPA) of all public health facilities and the 2007–2008 Rwanda Interim Demographic and Health Survey (RIDHS), five health facility samples and five household cluster displacements were created to simulate typical SPA samples and household cluster datasets. Facility datasets were matched with cluster datasets to create 36 paired datasets. Four geographic techniques were employed to link clusters with facilities in each paired dataset. The links between clusters and facilities were operationalized by creating health service variables from the RSPA and attaching them to linked RIDHS clusters. Comparisons between the original facility census and undisplaced clusters dataset with the multiple samples and displaced clusters datasets enabled measurement of error due to sampling and displacement.

Results

Facility sampling produced larger misclassification errors than cluster displacement, underestimating access to services. Distance to the nearest facility was misclassified for over 50% of the clusters when directly linked, while linking to all facilities within an administrative boundary produced the lowest misclassification error. Measuring relative service environment produced equally poor results with over half of the clusters assigned to the incorrect quintile when linked with a sample of facilities and more than one-third misclassified due to displacement.

Conclusions

At low levels of geographic disaggregation, linking independent facility samples and household clusters is not recommended. Linking facility census data with population data at the cluster level is possible, but misclassification errors associated with geographic displacement of clusters will bias estimates of relationships between service environment and health outcomes. The potential need to link facility and population-based data requires consideration when designing a facility survey.

     

Univariate and multivariate spatial models of health facility utilisation for childhood fevers in an area on the coast of Kenya

Background

Precise quantification of health service utilisation is important for the estimation of disease burden and allocation of health resources. Current approaches to mapping health facility utilisation rely on spatial accessibility alone as the predictor. However, other spatially varying social, demographic and economic factors may affect the use of health services. The exclusion of these factors can lead to the inaccurate estimation of health facility utilisation. Here, we compare the accuracy of a univariate spatial model, developed only from estimated travel time, to a multivariate model that also includes relevant social, demographic and economic factors.

Methods

A theoretical surface of travel time to the nearest public health facility was developed. These were assigned to each child reported to have had fever in the Kenya demographic and health survey of 2014 (KDHS 2014). The relationship of child treatment seeking for fever with travel time, household and individual factors from the KDHS2014 were determined using multilevel mixed modelling. Bayesian information criterion (BIC) and likelihood ratio test (LRT) tests were carried out to measure how selected factors improve parsimony and goodness of fit of the time model. Using the mixed model, a univariate spatial model of health facility utilisation was fitted using travel time as the predictor. The mixed model was also used to compute a multivariate spatial model of utilisation, using travel time and modelled surfaces of selected household and individual factors as predictors. The univariate and multivariate spatial models were then compared using the receiver operating area under the curve (AUC) and a percent correct prediction (PCP) test.

Results

The best fitting multivariate model had travel time, household wealth index and number of children in household as the predictors. These factors reduced BIC of the time model from 4008 to 2959, a change which was confirmed by the LRT test. Although there was a high correlation of the two modelled probability surfaces (Adj R ² = 88%), the multivariate model had better AUC compared to the univariate model; 0.83 versus 0.73 and PCP 0.61 versus 0.45 values.

Conclusion

Our study shows that a model that uses travel time, as well as household and individual-level socio-demographic factors, results in a more accurate estimation of use of health facilities for the treatment of childhood fever, compared to one that relies on only travel time.

     

Identifying gaps in the continuum of care for hypertension and diabetes in two Indian communities

Background

Non-communicable diseases (NCDs) represent the largest, and fastest growing, burden of disease in India. This study aimed to quantify levels of diagnosis, treatment, and control among hypertensive and diabetic patients, and to describe demand- and supply-side barriers to hypertension and diabetes diagnosis and care in two Indian districts, Shimla and Udaipur.

Methods

We conducted household and health facility surveys, as well as qualitative focus group discussions and interviews. The household survey randomly sampled individuals aged 15 and above in rural and urban areas in both districts. The survey included questions on NCD knowledge, history, and risk factors. Blood pressure, weight, height, and blood glucose measurements were obtained. The health facility survey was administered in 48 health care facilities, focusing on NCD diagnosis and treatment capacity, including staffing, equipment, and pharmaceuticals. Qualitative data was collected through semi-structured key informant interviews with health professionals and public health officials, as well as focus groups with patients and community members.

Results

Among 7181 individuals, 32% either reported a history of hypertension or were found to have a systolic blood pressure?≥?140 mmHg and/or diastolic ≥90 mmHg. Only 26% of those found to have elevated blood pressure reported a prior diagnosis, and just 42% of individuals with a prior diagnosis of hypertension were found to be normotensive. A history of diabetes or an elevated blood sugar (Random blood glucose (RBG) ≥200 mg/dl or fasting blood glucose (FBG) ≥126 mg/dl) was noted in 7% of the population. Among those with an elevated RBG/FBG, 59% had previously received a diagnosis of diabetes. Only 60% of diabetics on treatment were measured with a RBG <200 mg/dl. Lower-level health facilities were noted to have limited capacity to measure blood glucose as well as significant gaps in the availability of first-line pharmaceuticals for both hypertension and diabetes.

Conclusions

We found high rates of uncontrolled diabetes and undiagnosed and uncontrolled hypertension. Lower level health facilities were constrained by capacity to test, monitor and treat diabetes and hypertension. Interventions aimed at improving patient outcomes will need to focus on the expanding access to quality care in order to accommodate the growing demand for NCD services.

     

Dizziness as a geriatric condition among rural community-dwelling older adults

Background

Dizziness is a common symptom in older adults. The majority of those with dizziness tend to have more than one risk factor, suggesting that dizziness is a multifactorial geriatric condition. Therefore, associated factors must be determined to permit risk-reduction approaches.

Objective

To examine the associations between dizziness and socio-demographic, physical, functional and psychological health factors among older persons living in the Andes Mountains.

Design

Population-based cross-sectional study.

Settings/Participants

One thousand six hundred ninety-two community-living people aged 60 years and over living in four rural and suburban areas of villages in coffee-grower zones in the Colombian Andes Mountains.

Measurements

Outcome measures included self-reporting of dizziness as a symptom experienced either very frequently or continuously during the last month. Independent variables were demographic, socioeconomic and social factors; disease and biomedical factors; functional status and performance-based measures; and psychological factors such as depressive symptoms and self-rated health.

Results

Dizziness was reported by 15.2% of participants in the study. Variables independently associated with dizziness were: number of chronic conditions, visual impairment, and use of more than four medications. Independently associated psychological variables were: poor self-perceived health, cognitive impairment and depression. Health and psychological factors accounted for 85% of dizziness.

Conclusion

Older persons who reported dizziness were more physically frail, with more instances of chronic conditions and sensory impairments, and had poor self-perceptions of their health. Biomedical and psychological factors showed a strong independent association with dizziness. A multifactorial intervention targeting the identified factors would reduce dizziness in older people. However, this approach may need to address different sets of specific factors related to the dizziness categories.

     

Factors influencing consumption of fruits and vegetables in older adults in New Orleans,Louisiana

Background: Objectives

The objective of this study was to identify demographic, social and structural factors associated with intake of fruit and vegetables in older adults in New Orleans, Louisiana.

Design

A crosssectional randomly sampled, address-based telephone survey of households in Orleans Parish, Louisiana was conducted with the household’s main grocery shopper.

Setting

All participants were in the New Orleans metro area and were surveyed in 2011.

Participants

Participants were 2,834 residents identified as the households’ main grocery shopper in Orleans Parish, Louisiana. Participants were primarily female (75%), African-American (53%), approximately 10 percent of the sample reported receipt of government assistance. Approximately 37% of the sample was age 65 and older.

Measurements

Measures included a telephone administered survey assessing demographic characteristics, food intake, access to supermarkets and other food sources, transportation, selfreported health, and frequency of grocery shopping.

Results

Older adults consumed fewer fresh fruits and vegetables (FV) than younger adults (p<0.01). Bivariate associations with decreased FV included older age, receipt of government assistance, African American race, use of mobility aid, and poorer health. Multivariate factors associated with lower consumption include age, African American race, and poorer self-reported health. Women reported more fruit and vegetable consumption than men.

Conclusions

FV consumption is associated with improved health and reduced mortality. Older adults are less likely to consume fruits and vegetables, therefore addressing reduced FV consumption in older adults is a potential target for improving health outcomes in older adults. Specifically targeting African Americans and those with poorer health, as well as males may be an important focus for interventions.

     

Combining survey data,GIS and qualitative interviews in the analysis of health service access for persons with disabilities

Background

Equitable access to health services is a key ingredient in reaching health for persons with disabilities and other vulnerable groups. So far, research on access to health services in low- and middle-income countries has largely relied on self-reported survey data. Realizing that there may be substantial discrepancies between perceived and actual access, other methods are needed for more precise knowledge to guide health policy and planning. The objective of this article is to describe and discuss an innovative methodological triangulation where statistical and spatial analysis of perceived distance and objective measures of access is combined with qualitative evidence.

Methods

The data for the study was drawn from a large household and individual questionnaire based survey carried out in Namibia and Malawi. The survey data was combined with spatial data of respondents and health facilities, key informant interviews and focus group discussions. To analyse access and barriers to access, a model is developed that takes into account both measured and perceived access. The geo-referenced survey data is used to establish four outcome categories of perceived and measured access as either good or poor. Combined with analyses of the terrain and the actual distance from where the respondents live to the health facility they go to, the data allows for categorising areas and respondents according to the four outcome categories. The four groups are subsequently analysed with respect to variation in individual characteristics and vulnerability factors. The qualitative component includes participatory map drawing and is used to gain further insight into the mechanisms behind the different combinations of perceived and actual access.

Results

Preliminary results show that there are substantial discrepancies between perceived and actual access to health services and the qualitative study provides insight into mechanisms behind such divergences.

Conclusion

The novel combination of survey data, geographical data and qualitative data will generate a model on access to health services in poor contexts that will feed into efforts to improve access for the most vulnerable people in underserved areas.

     

The role of perceived pollution and health risk perception in annoyance and health symptoms: a population-based study of odorous air pollution

Objectives

Health effects associated with air pollution at exposure levels below toxicity may not be directly related to level of exposure, but rather mediated by perception of the air pollution and by top-down processing (e.g., beliefs that the exposure is hazardous). The aim of the study was to test a model that describes interrelations between odorous air pollution at non-toxic exposure levels, perceived pollution, health risk perception, annoyance and health symptoms.

Methods

A population-based questionnaire study was conducted in a Swedish community of residents living near a biofuel facility that emitted odorous substances. Individuals aged 18–75 years were selected at random for participation (n = 1,118); 722 (65 %) agreed to participate. Path analyses were performed to test the validity of the model.

Results

The data support a model proposing that exposure level does not directly influence annoyance and symptoms, and that these relations instead are mediated by perceived pollution and health risk perception.

Conclusions

Perceived pollution and health risk perception play important roles in understanding and predicting environmentally induced annoyance and health symptoms in odorous environments at non-toxic levels of exposure.
