The Shortfalls of Mental Health Compartment Models: A Call to Improve Mental Health Investment Cases in Developing Countries

OBJECTIVES

There are irregularities in investment cases generated by the Mental Health Compartment Model. We discuss these irregularities and highlight the costing techniques that may be introduced to improve mental health investment cases.

METHODS

This analysis uses data from the World Bank, the World Health Organization Mental Health Compartment Model, the United Nations Development Program, the Kenya Ministry of Health, and Statistics from the Kenyan National Commission of Human Rights.

RESULTS

We demonstrate that the Mental Health Compartment Model produces irrelevant outcomes that are not helpful for clinical settings. The model inflated the productivity gains generated from mental health investment. In some cases, the model underestimated the economic costs of mental health. Such limitation renders the investment cases poor in providing valuable intervention points from the perspectives of both the users and the providers.

CONCLUSIONS

There is a need for further calibration and validation of the investment case outcomes. The current estimated results cannot be used to guide service provision, research, and mental health programming comprehensively.

Attitude towards Antipsychotic Medications in Patients Diagnosed with Schizophrenia: A Cross-Sectional Study at Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia

BACKGROUND

Poor attitude towards antipsychotic drugs is high, and it is a factor for non-adherence to treatment. This increases the risk of relapse, associated healthcare utilization, and costs. This study aimed to assess attitude towards antipsychotic medication among patients with schizophrenia.

OBJECTIVES

The aim of this institution based cross-sectional study was to assess attitude towards antipsychotic medications and associated factors among patients with schizophrenia who attend the outpatient clinics at Amanuel Mental Specialized Hospital, 2018.

METHODS

In a cross-sectional study, 393 schizophrenic patients from Amanuel Mental Specialized Hospital were recruited by a systematic random sampling technique. Drug Attitude Inventory (DAI-10) was used to assess attitude, experience, and belief about antipsychotics. Glasgow antipsychotic side effect scale modified version, positive and negative syndrome scale, and Birch wood's insight scale for psychosis were the instruments used to assess the associated factors. Simple and multiple linear regression analysis models were fitted, and the adjusted unstandardized beta (β) coefficient at 95% confidence interval was used.

RESULTS

The mean score of attitude towards antipsychotic medications was 6.51 with standard deviation (SD) of 2.22. In multiple linear regression, positive symptoms (β= -0.07, 95% CI: (-0.09, -0.05)), negative symptoms (β= -0.04, 95% CI: (-0.06,-0.02)), shorter (≤5 years) duration of illness (β= -0.39, 95% CI: (-0.63, -0.15)), first generation antipsychotics (β = -0.35, 95% CI: (-0.55,-0.14)), having sedation (β= -0.28, 95% CI: (-0.52, -0.02)), and extra-pyramidal side effects (β= -0.34, 95% CI: (-0.59,-0.09)) were factors negatively associated with attitude towards antipsychotic medication treatment. Insight to illness (β= 0.24, 95% CI: (0.20, 0.27) was a factor positively associated with attitude towards antipsychotic medications.

CONCLUSION

The result suggests that the mean score of participants' attitude towards antipsychotic medications was good. Prevention of side effects particularly due to first generation antipsychotics is necessary.

Level of community mental health literacy in sub-Saharan Africa: current studies are limited in number, scope, spread, and cognizance of cultural nuances

BACKGROUND

The combination of high prevalence of mental disorders and the scarcity of resources to care for them in sub-Saharan Africa underscores the need for good mental health literacy as a potential mental health resource.

AIM

To conduct a systematic review of the findings of studies that have examined aspects of mental health literacy among community dwellers in sub-Saharan Africa.

METHODS

A search was conducted using local and international indexes like MEDLINE, EMBASE and PsychInfo.

RESULTS

Only 19 studies from eight different countries met inclusion criteria. Key aspects of the functional mental health literacy that has been examined include recognition of mental disorders, knowledge about causation, and treatment preferences. The modes of seeking mental health information are yet to be examined. Some studies utilized a methodology that allowed for respondents to use local labels to describe their understanding of various mental disorders. Otherwise, respondents were largely unable to label orthodox psychiatry syndromes correctly. Supernatural and ultra-human views were rampant, and alternative mental health services were mostly preferred. Quantitative modes of assessment were the most common, and authors-especially those that adopted this mode of assessment-did not take full cognizance of socio-cultural underpinnings of the concept of mental health literacy in their conclusion and recommendations.

CONCLUSION

There is need for more studies to adopt more comprehensive approaches to the assessment of mental health literacy. The outcomes of such studies will provide the right context for making profound statements on the level of knowledge and skills for mental health promotion in sub-Saharan Africa.

Closing the mental health treatment gap in South Africa: a review of costs and cost-effectiveness

Background

Nearly one in three South Africans will suffer from a mental disorder in his or her lifetime, a higher prevalence than many low- and middle-income countries. Understanding the economic costs and consequences of prevention and packages of care is essential, particularly as South Africa considers scaling-up mental health services and works towards universal health coverage. Economic evaluations can inform how priorities are set in system or spending changes.

Objective

To identify and review research from South Africa and sub-Saharan Africa on the direct and indirect costs of mental, neurological, and substance use (MNS) disorders and the cost-effectiveness of treatment interventions.

Design

Narrative overview methodology.

Results and conclusions

Reviewed studies indicate that integrating mental health care into existing health systems may be the most effective and cost-efficient approach to increase access to mental health services in South Africa. Integration would also direct treatment, prevention, and screening to people with HIV and other chronic health conditions who are at high risk for mental disorders. We identify four major knowledge gaps: 1) accurate and thorough assessment of the health burdens of MNS disorders, 2) design and assessment of interventions that integrate mental health screening and treatment into existing health systems, 3) information on the use and costs of traditional medicines, and 4) cost-effectiveness evaluation of a range of specific interventions or packages of interventions that are tailored to the national context.

Mental illness and lost income among adult South Africans

PURPOSE

Little is known regarding the links between mental disorder and lost income in low- and middle-income countries. The purpose of this study was to investigate the association between mental disorder and lost income in the first nationally representative psychiatric epidemiology survey in South Africa.

METHODS

A probability sample of South African adults was administered the World Health Organization Composite International Diagnostic Interview schedule to assess the presence of mental disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders, version IV.

RESULTS

The presence of severe depression or anxiety disorders was associated with a significant reduction in earnings in the previous 12 months among both employed and unemployed South African adults (p = 0.0043). In simulations of costs to individuals, the mean estimated lost income associated with severe depression and anxiety disorders was $4,798 per adult per year, after adjustment for age, gender, substance abuse, education, marital status, and household size. Projections of total annual cost to South Africans living with these disorders in lost earnings, extrapolated from the sample, were $3.6 billion. These data indicate either that mental illness has a major economic impact, through the effect of disability and stigma on earnings, or that people in lower income groups are at increased risk of mental illness. The indirect costs of severe depression and anxiety disorders stand in stark contrast with the direct costs of treatment in South Africa, as illustrated by annual government spending on mental health services, amounting to an estimated $59 million for adults.

CONCLUSIONS

The findings of this study support the economic argument for investing in mental health care as a means of mitigating indirect costs of mental illness.

Mental disorders, health inequalities and ethics: A global perspective

The global burden of neuropsychiatry diseases and related mental health conditions is enormous, underappreciated and under resourced, particularly in the developing nations. The absence of adequate and quality mental health infrastructure and workforce is increasingly recognized. The ethical implications of inequalities in mental health for people and nations are profound and must be addressed in efforts to fulfil key bioethics principles of medicine and public health: respect for individuals, justice, beneficence, and non-malfeasance. Stigma and discrimination against people living with mental disorders affects their education, employment, access to care and hampers their capacity to contribute to society. Mental health well-being is closely associated to several Millennium Development Goals and economic development sectors including education, labour force participation, and productivity. Limited access to mental health care increases patient and family suffering. Unmet mental health needs have a negative effect on poverty reduction initiatives and economic development. Untreated mental conditions contribute to economic loss because they increase school and work absenteeism and dropout rates, healthcare expenditure, and unemployment. Addressing unmet mental health needs will require development of better mental health infrastructure and workforce and overall integration of mental and physical health services with primary care, especially in the developing nations.

Economic burden of cholera in the WHO African region

BACKGROUND

In 2007, various countries around the world notified 178677 cases of cholera and 4033 cholera deaths to the World Health Organization (WHO). About 62% of those cases and 56.7% of deaths were reported from the WHO African Region alone. To date, no study has been undertaken in the Region to estimate the economic burden of cholera for use in advocacy for its prevention and control. The objective of this study was to estimate the direct and indirect cost of cholera in the WHO African Region.

METHODS

Drawing information from various secondary sources, this study used standard cost-of-illness methods to estimate: (a) the direct costs, i.e. those borne by the health-care system and the family in directly addressing cholera; and (b) the indirect costs, i.e. loss of productivity caused by cholera, which is borne by the individual, the family or the employer. The study was based on the number of cholera cases and deaths notified to the World Health Organization by countries of the WHO African Region.

RESULTS

The 125018 cases of cholera notified to WHO by countries of the African Region in 2005 resulted in a real total economic loss of US$39 million, US$ 53.2 million and US$64.2 million, assuming a regional life expectancies of 40, 53 and 73 years respectively. The 203,564 cases of cholera notified in 2006 led to a total economic loss US$91.9 million, US$128.1 million and US$156 million, assuming life expectancies of 40, 53 and 73 years respectively. The 110,837 cases of cholera notified in 2007 resulted in an economic loss of US$43.3 million, US$60 million and US$72.7 million, assuming life expectancies of 40, 53 and 73 years respectively.

CONCLUSION

There is an urgent need for further research to determine the national-level economic burden of cholera, disaggregated by different productive and social sectors and occupations of patients and relatives, and national-level costs and effectiveness of alternative ways of scaling up population coverage of potable water and clean sanitation facilities.

Economic burden of diabetes mellitus in the WHO African region

Background

In 2000, the prevalence of diabetes among the 46 countries of the WHO African Region was estimated at 7.02 million people. Evidence from North America, Europe, Asia, Latin America and the Caribbean indicates that diabetes exerts a heavy health and economic burden on society. Unfortunately, there is a dearth of such evidence in the WHO African Region. The objective of this study was to estimate the economic burden associated with diabetes mellitus in the countries in the African Region.

Methods

Drawing information from various secondary sources, this study used standard cost-of-illness methods to estimate: (a) the direct costs, i.e. those borne by the health systems and the families in directly addressing the problem; and (b) the indirect costs, i.e. the losses in productivity attributable to premature mortality, permanent disability and temporary disability caused by the disease. Prevalence estimates of diabetes for the year 2000 were used to calculate direct and indirect costs of diabetes mellitus. A discount rate of 3% was used to convert future earnings lost into their present values. The economic burden analysis was done for three groups of countries, i.e. 6 countries whose gross national income (GNI) per capita was greater than 8000 international dollars (i.e. in purchasing power parity), 6 countries with Int$2000–7999 and 33 countries with less than Int$2000. GNI for Zimbabwe was missing.

Results

The 7.02 million cases of diabetes recorded by countries of the African Region in 2000 resulted in a total economic loss of Int$25.51 billion (PPP). Approximately 43.65%, 10.03% and 46.32% of that loss was incurred by groups 1, 2 and 3 countries, respectively. This translated into grand total economic loss of Int$11,431.6, Int$4,770.6 and Int$ 2,144.3 per diabetes case per year in the three groups respectively.

Conclusion

In spite of data limitations, the estimates reported here show that diabetes imposes a substantial economic burden on countries of the WHO African Region. That heavy burden underscores the urgent need for increased investments in the prevention and management of diabetes.

Barriers in the mind: promoting an economic case for mental health in low- and middle-income countries

In recent years, policy makers in high-income countries have placed an increasing emphasis on the value of maintaining good mental health, recognizing the contribution that this makes to quality of life, whilst ever more mindful of the socio-economic consequences of poor mental health. The picture in many other parts of the world is much less encouraging; policy attention and resources are still directed largely at communicable diseases. We reflect on some of the challenges faced in these countries and outline the role that economic evidence could play in strengthening the policy case for investment in mental health. Clearly this should include assessment of the economic impact of strategies implemented outside, as well as within the health sector. The ways in which mental health services are delivered is also of critical importance. Non-governmental organizations (NGOs) have long been shown to be key stakeholders in the funding, coordination and delivery of these services in high-income countries. Their role in low- and middle-income countries, where infrastructure and policy focus on mental health are more limited, can be even more vital in overcoming some of the barriers to the development of mental health policy and practice.
