MSc (Med), Population-Based Field Epidemiology, Faculty of Health Sciences, University of the Witwatersrand / Introduction: As people age, they become more vulnerable to ill‐health from acute and increasingly chronic diseases. This has elevated health care demand and utilisation in the elderly especially in the developed countries. In developing countries, ageing so far has not been a serious public health concern because of smaller number of older people in these countries. Recently however, the number of older adults in Sub‐Saharan Africa has increased rapidly, projected to stand at 130 million by 2050 from 30 million in 2000. This increase mirrors health related problems and has obvious public health implications. Thus, there is an urgent need to recognise and respond to health needs of the ageing populations in Africa. Objectives: To describe health care utilisation, health status and compare the proportions of adults aged 50+ years with moderate and poor health status to those with good health status. Another objective was to identify factors associated with health care utilisation among the elderly population in Kassena‐Nankana district, Ghana in 2007. Methods: Secondary analysis was performed on a cross‐sectional dataset collected between February and July 2007 through face‐to‐face interviews within the settings of the Navrongo DSS in Ghana. A total of 594 adults aged 50+ years participated in this study. The outcome variable was health care utilisation occurring in the last three years. Explanatory variables were grouped as predisposing, enabling and need‐related factors according to the behavioural model of health services utilisation. The predisposing variables were age, sex, marital status, ethnic background, education and smoking or use of smokeless tobacco. Occupation and financial position were included as enabling factors. Medical history of chronic conditions, self‐reported health status, difficulty with self‐care (e.g. bathing, washing, dressing etc), difficulty with picking up things in the last 30 days and cognitive impairment were grouped as need‐related factors. Logistic 382128 v univariate and multivariate regression analyses were conducted. STATA 10 statistical software was used to carry out this process. Results: The proportion of study participants reporting poor, moderate and good health status were 14.2%, 43.3% and 42.5% respectively. About one‐third (31%) of the study participants reported to have utilised health care services in the last 3 years. The following factors were identified as determinants of health care utilisation among the elderly rural Ghanaians: a medical history of at least one chronic condition (OR = 2.36; 95% CI = [1.49 – 3.75]; p < 0.001), self‐perceived health (OR = 2.00; 95% CI = [1.11 ‐ 3.59]; p = 0.021), age group (OR = 1.68; 95% CI = [1.07 ‐ 2.64]; p = 0.025), cognitive impairment (OR = 1.26; 95% CI = [1.02 – 1.56]; p = 0.032) and difficulty with picking up things in the last 30 days (OR = 0.76; 95% CI = [0.61 ‐ 0.96]; p = 0.021). Conclusion: Medical history of at least one chronic condition and poor perceived health status were the most pervasive determinants of health care utilisation. In addition, age group (60‐69 years), severe cognitive impairment and severe difficulty with picking up things in the last 30 days presented a significant influence on health care utilisation among the elderly population in rural Ghana. Recommendations: Provision of home‐based health care services could facilitate their accessibility for the elderly especially those with various difficulties. These factors could help health policy makers and health service providers identify and understand the situation of the elderly rural Ghanaians and consequently create conducive environment for providing appropriate health care services.

A severe burn is a trauma fraught with stress and pain and may change the entire course of life. This thesis focuses on care utilisation, care experiences and patient satisfaction after a severe burn. The patients studied were treated at the Burn Unit at Uppsala University Hospital between 1980 and 2006. Burn-related health was examined using the Burn Specific Health Scale-Brief (BSHS-B), personality traits with the Swedish universities Scales of Personality (SSP), psychological symptoms using the Hospital Anxiety and Depression scale (HADS), symptoms of posttraumatic stress with the Impact of Event Scale-Revised (IES-R) and satisfaction with care using the Patient Satisfaction-Results and Quality (PS-RESKVA) questionnaire. Those utilising care years after injury reported poorer functioning on three of the BSHS-B subscales. Personality traits had a greater impact on care utilisation than injury severity. Social desirability was lower among care utilisers and was associated with burn-related health aspects. The participants reported a low level of negative care experiences, the most common of which was Powerlessness. Most patients were satisfied with care, more with quality of contact with the nursing staff, and less with treatment information. Multiple regressions showed that the BSHS-B Interpersonal relationships subscale was an independent variable related to all measured aspects of patient satisfaction. The highest adjusted R2 was 0.25. In a prospective assessment with multiple regression analyses, Age and Education, the personality traits of Stress susceptibility, Trait irritability, Detachment and Social desirability, in addition to the post-traumatic stress symptoms Intrusion and Hyperarousal, were predictors of satisfaction with care. The highest adjusted R2 was 0.19. The thesis has pointed out that interpersonal factors are related to care utilisation as well as satisfaction with care. However, satisfaction with care was only moderately associated with health and individual characteristics, which may imply that the care itself is of major importance.

It has been suggested that persons with intellectual disabilities (ID) manifest the full range of mental health problems. The main purpose of this thesis is to adapt and evaluate two clinical assessment instruments and to investigate the occurrence of mental health problems as well as psychiatric care utilisation in persons with ID. The psychometric properties of a Swedish version of the two instruments [Reiss Screen for Maladaptive Behaviour (RSMB) and the Psychopathology Inventory for Mentally Retarded Adults (PIMRA)] were investigated in a random, institutional and clinical sample of administratively defined (ADDEF) adults with ID (n = 199). The analyses suggest that the RSMB could be used as intended by staff as a primary screening device for the identification of mental health problems in persons with ID, and that the PIMRA had a potential to identify individuals with a specific mental disorder. The psychometric evaluation reveals that the Swedish versions of the RSMB and PIMRA measure a construct related to the diagnostic categories in the DSM-III-R and DSM-IV. This construct could be conceptualised as mental health problems. The RSMB and PIMRA results show that the overall occurrence of mental health problems in ADDEF samples of persons with ID (175 men and 148 women) ranged from 34 to 64%. The preliminary level of ID was mild (23%), moderate (39%) and severe (38%). The most common mental health problems were aggressive and self-injurious behaviours, depression, anxiety and adjustment disorders. In registered patients receiving out- or in-patient psychiatric care the occurrence of adults with an ICD-10 diagnosis of ID was approximately 1% (70 to 90% had a mild level of ID). In contrast to the high frequency of mental health problems reported, psychiatric care was used infrequently. This tendency is particularly evident in persons with moderate and severe ID.

The aim of this thesis is to contribute to existing knowledge. If the knowledge is not useful in building society it has limited value. In order to be a tool for decision-makers, Preventive Home Visits (PHVs) are described and discussed according to a realist synthesis approach. The premise of this approach is that a single trial cannot tell the whole story and that understanding theoutcome pattern is much more important than seeking regularities in results across different trials. In order to understand the o utcome pattern, the PHV strategy in Nordmaling is examined against other trials and scientific work, and also in grey literature such as reports and workingpapers. An increasing population of seniors means that resources for health and elderly care are being scrutinised in order to achieve the best possible health for the money invested. PHVs represent one strategy that attempts to promote health among independent seniors. This thesis is a multidisciplinary study aiming to gain knowledge about the effects of PHVs and to understand the mechanisms of importance when implementing this particular strategy. The point of departure is a study conducted in Nordmaling in the north of Sweden among healthy seniors aged 75 years and over. The study, conducted as a controlled trial during 2000 and 2001, showed a decrease in mortality as well as the utilisation of care, and an improvement in indicators of perceived health. Cost analyses showed significant savings for the municipality following a reduction in the use of home help. These and other savings combined with costs of the intervention were related to saved life years and used to conduct health economic analyses. Medical and social records from the primary health centre and the municipality, along with official registers provided information for modelling health economic analyses from a lifetime perspective. Results showed that the costs of PHVs were less than 10 000 Euros per gained life year, against an acceptable level of cost effectiveness of 50 000 Euros. Using a shorter time perspective, the result was even more favourable for PHVs. It was evident that the time window used in the analyses, the normative choice of including future healthcare costs or not, and how to handle the value of the seniors’ production were important factors in determining the results. Two years after the trial, in-depth interviews were conducted with 5 seniors who had experienced PHVs, in order to gain understanding of the outcome of the PHV trial in Nordmaling. Participants were selected with respect to their health and how they responded to advice given during the PHV trial. Grounded Theory was used to analyse the interviews. Seniors who used autonomous coping strategies in everyday life gained less from PHVs than other seniors. All participants could benefit from PHVs, but in order for these to be successful it was important for the home visitor to be professional and to understand how the different coping strategies of seniors worked. Taken together, the different aspects of this study raised normative questions that are discussed in this thesis. One, whether the production of seniors has any monetary value in health economic analyses conducted from a societal perspective, was addressed in a smaller diary study where 23 seniors were asked to keep a diary in order to identify everything they did over a oneweek period. It was evident that most of the respondents “produced” a lot, however the production of seniors is rarely taken into account in health economic analyses. The concept of “senior production” includes both the market value of what seniors do, as well as the value of what society can avoid doing if the seniors are independent and healthy.

Background: Along with the austerity measures introduced in many countries, the economic crisis affecting Europe since 2008 seems to have impacted many aspects of the health of the Spanish population and has had a negative effect on the provision health services. An increasing body of knowledge has shown a clear impact of the current crisis on suicidal behaviour and mental health, and a less consistent effect on physical health and access to healthcare. However, little is known about the impact of the crisis on social inequalities in health and healthcare access, an area on which the present study seeks to shed light in the context of Spain, and specifically Andalusia, a region hit very hard by the crisis. Objective: To study the impact of the economic crisis starting in 2008 on health, health inequalities and health service utilisation in Spain and Andalusia and the roles of socio-demographic factors in these associations. Methods: Death rates were analysed to study the annual percent change in overall and cause-specific mortality in Spain between 1999 and 2011, and the Longitudinal Database of the Andalusian Population was used to study educational inequalities in overall mortality from 2002 to 2010 (study 1). To calculate suicide attempt rates, information from 2003 to 2012 on 11,494 men and 12,886 women provided by the Health Emergencies Public Enterprise Information System in Andalusia was utilised. The association between unemployment and suicide attempts was studied through linear regression models (study 2). Two waves of the Andalusian Health Survey (2007 and 2011–12) provided data for the third and fourth studies of this thesis. Educational and employment status inequalities in poor mental health in relation with the crisis were analysed through Poisson regression models (study 3). The change in inequalities (pre-crisis–crisis) in health care utilisation outcomes (general practitioner, specialist, hospitalisation and emergency attendance) was measured by the change in horizontal inequality indices. A decomposition analysis of change in inequality between periods was performed using the Oaxaca approach (study 4). Results: Study 1: Overall mortality in Spain decreased steadily during the period, with annual percent changes of -2.44% in men and -2.20% in women. An increase in educational inequality in mortality was observed in men in Andalusia. In women, the inequalities instead remained stable. Suicide mortality showed a downward trend in both sexes in Spain. Study 2: A sharp increase in suicide attempts in Andalusia was detected after the onset of the crisis in both sexes, with adults aged 35 to 54 years being the most affected. Suicide attempts were associated with unemployment rates only in men. Study 3: Poor mental health increased in working individuals with secondary and primary studies during the crisis compared to the pre-crisis period, while it decreased in the university study group. However, in unemployed individuals poor mental health increased only in the secondary studies group. Financial strain could partly explain the crisis effect on mental health among the unemployed. Study 4: Horizontal inequality in utilisation changed to a greater equality or a more pro-poor inequality in both sexes. In the decomposition analysis, socioeconomic position and health status showed greater contributions to the changes in inequalities. Conclusion: This thesis illustrates the complexity of the influences of the current economic crisis on health inequalities in a Southern European region. Specifically, no noticeable effects of the crisis on overall and suicide mortality were detected; instead, increasing educational inequalities in mortality in men and a large increase in suicide attempts in middle aged men and women were observed. The deterioration in poor mental health was mainly detected in those of intermediate educational level. Economic conditions such as unemployment and financial strain proved to be relevant. Finally, in the light of no increased inequalities in healthcare utilisation, the universal coverage health system seems to buffer the deleterious effect of the crisis and austerity policies in this context.

Background. In Sweden 10 percent (550,000) of the labour force, aged 18 to 65 years are disability pensioners and about four percent are on sick leave. The knowledge of the course from healthy individual to disability pensioner is not well known and was the theme of this thesis. Objectives, Material and Methods. The aims of the thesis were to follow the study population regarding sickness absence, health care utilisation, quality of life, and survival. Population based data including 14,538 women and men from three cities in Sweden were used, of whom 1,952 were granted a disability pension at baseline or received one during follow up. Register data, including sickness spells, health care utilisation, and mortality data during 30 years of follow up, and questionnaire data including socio-economic and quality of life data were used. Results. The most powerful determinant for being granted a disability pension was cumulative annual sick leave days, more powerful than all other tested determinants together. The degree of explanation for all determinants combined was 96%. Health care utilisation among disability pensioners continued to be high also after disability pension, 2.3 times higher for hospital admissions and 8 times higher for primary health case appointments than among referents. Disability pensioners had lower quality of life than non-pensioners and old age pensioners. For those who became disability pensioners after the baseline measurements quality of life measures decreased progressively until disability pension was granted and were then stabilised on a low level. During follow up 525 (7.6%) subjects died. Compared with subjects who did not become disability pensioners the hazards ratio was 2.78 among women and 3.43 among men, even when the effect of a number of other outcome affecting variables were taken into account. The mortality differences were not explained by underlying disease. Conclusions. The risk of disability pension may be predicted but only late in the course of events. Disability pensioners continue to have a high level of health care utilisation, and have a worse quality of life development and a higher mortality rate than non-pensioners. Given the unfavourable outcome of disability pension, other means of managing the reduced work capacity might be considered.
