Families with children

This research project looks at mothers who have given birth in the 2000s and their families from different perspectives. The research data covers 60 percent of mothers who gave birth in 1999–2009. The factual content of the data comprises Kela benefits, benefit periods and background information gathered from the labour force survey conducted by Statistics Finland. The sample has approx. 33,000 mothers per annum.

By using registers of Kela and Statistics Finland, the mothers' spouses have also been found and the same background information is available on them as well. This representative sample is used in both cross-sectional and longitudinal research frames. Individual families with children may be followed up to 10–11 years.

The objectives of this research project are

  1. to produce information on the interconnectedness of family leave reforms and how family leaves are distributed between parents and on how family leave reforms affect mothers' and fathers' labour market positions,
  2. to produce more accurate information particularly on such families with children which have previously been studied only marginally or not at all due to small sample sizes, and
  3. to look at how companies' background features explain the use of family leaves and the allocation of paid leaves.

The following working papers have been completed to date:

Family leaves 2013 – a population survey

The project aims to explore the use of family leaves among parents of small children. The purpose is to examine the experiences and opinions of parents concerning parental leaves and child home care leaves, the use of family leaves by fathers and the reconciliation of family and working life in families with children.

The study material was collected by means of an online questionnaire survey targeting mothers and fathers of children born in 2011. For the survey, the respondents were sampled from Kela’s registers and the material collection took place in autumn 2013.  The data obtained from Kela’s registers are used to supplement the questionnaire data.

The study is the continuation of a questionnaire study conducted in 2006 and is implemented jointly with the National Institute for Health and Welfare (THL). At Kela Research, the questionnaire has been utilised in the abovementioned ‘Families with children’ project and related publications.

In addition to the population survey, two specifically targeted surveys were carried out.  The ‘Multiple-birth families’ survey was targeted to mothers who had given birth to twins or triplets in 2011, and the ‘Young mothers’ survey, correspondingly, to mothers aged under 22 who had given birth in 2011.   Separate reports will be published on the Multiple-birth families and Young mothers surveys.

Child care arrangements in families with children in Helsinki in the 2010s (HELA)

Information concerning child care arrangements in families is readily available for those parents and children that are receiving family leave benefits from Kela. In contrast, there are no individual or family level statistics on the use of early childhood education services. How many families are using early childhood education services and how does the family structure affect the choices? What kind of child care paths do children have before they start school? How does a long-term illness of either the child or parents affect the choices? What kind of child care arrangements are made in families when the number of children in the family increases, or when one or both parents are unemployed or work part-time, either voluntarily or due to the lack of full-time work? 

The research project HELA aims to find answers to the aforementioned questions. The first task is to compile research material which, for the first time, utilises longitudinal data both on the use of early childhood education services and on other child care solutions made by families.

The research material is constructed by combining data on children in day care in the years 2008–2015, as obtained from the Department of Early Education and Care of the City of Helsinki, and data on all families with children in Helsinki. The material will be updated during the project until the year 2017. In addition, the combined research material will include data on the families’ incomes, including the family leave benefits paid by Kela, other income and income transfers, as well as unemployment periods.

The project is conducted in cooperation by Kela Research, City of Helsinki Urban Facts and City of Helsinki Early Education and Care. The research is a part of the consortium projects ‘Tackling Inequalities in Time of Austerity (TITA)’ and ‘Work, Inequality and Public Policy (WIP)’, which are funded by the Strategic Research Council at the Academy of Finland.

The direction of pension security

The project entitled ‘The direction of pension security’ aims to provide updated and new information about the realisation, sufficiency and development of pension security in various groups, such as women and men, different age groups, or the recipients of minimum pension security, survivors’ pension and disability pensions. Another area of interest is the citizens’ opinions concerning a good and fair pension system and the pension reform in 2017.

As part of the project, a population survey will be conducted that utilises the ISEA (International Survey of Economic Attitudes) survey questions concerning opinions and attitudes related to pension security. This facilitates the comparison of changes that have taken place in opinions and attitudes in Finland over the course of two decades.  The study concerning the pension reform 2017 is conducted in cooperation with the Finnish Centre for Pensions (ETK).

Project period: 1 September 2015–31 December 2018.

The impacts of survivors’ pension on welfare

The project aims to analyse the role of survivors’ pensions in terms of subsistence and health, thereby facilitating the evaluation of the risks possibly included in the suggested plans to renew the survivors’ pension system. Moreover, the project aims to explore citizens’ opinions about the survivors’ pension security, by utilising the questions about widow(er)’s pension security from the survey material completed in early 2016 (the material was collected jointly with the ‘Direction of pension security’ project).

Project period: 25 March 2014–31 December 2017.

Time and processes before disability pension

The study is being undertaken jointly by the Finnish Centre for Pensions (ETK) and Kela for the purpose of investigating the factors contributing to retirement with disability pension. In order to understand the process that leads to disability pensioning and in terms of possible preventive measures, it is important to investigate the routes and mechanisms within the different social security systems through which individual persons end up becoming recipients of disability pension. The objective is, in particular, to identify those stages of the process before disability pensioning in which the process might take a different turn and enable one’s return to working life. The study will produce topical register-based data on those factors that help in recovering one’s work ability and return to work after a sickness leave. The subjects’ health status, unemployment periods, sickness leaves as well as earlier pension and rehabilitation decisions before the application for disability pension are examined for the study.  The material is comprised of extensive register-based material on working-age population, including data sampled from different registers.

The project is in progress during the period 2012–2018.

New models of operation in dental care

The project consists of three sub-studies. In the first one the results of partnership projects between private and public dental services will be evaluated. The study follows private sector patients' use of services and the types of procedures (and their costs) performed on them. Dental procedures and costs of patients in the partnership project are compared to procedures and visits of other patients using private services.

The second sub-study looks to evaluate the operations of different companies in the dental care market and how changes in the market affect procedures performed on patients, treatment practices and the frequency of use. In the third sub-study the effects of a voucher trial on the compensations for dental expenses and the service providers' pricing are evaluated by using Helsinki as a case example.

The data used in the sub-studies is the Kela register of compensations for medical expenses 2008–2015 and the data is analysed with applicable statistical methods.

Follow-up of changes to medicine reimbursements in 2016

As of the start of 2016, several changes were made to the system of medicine reimbursements for the purpose of reducing the expenditure from medicine reimbursements (Government proposals 330/2014, 106/2015 and 128/2015). Changes with a direct effect on the patient’s out-of-pocket payments included the introduction of an annual initial deductible (non-reimbursable sum), the increase of the compensation percentage in the basic refund category and the increase of fixed deductibles. The aim of the study is to evaluate the influence of these changes, which became valid in 2016, on the deductibles paid by the patients, their purchasing behaviours and the medicine reimbursements within the sickness insurance system. The changes are analysed at a general level from the perspectives of both the sickness insurance system and patients, and also at a more detailed level specifically for different patient and population groups on the basis of data on special refund entitlements as well as on socioeconomic and demographic factors. Another objective of the study is to produce data for comparison with the results obtained by advance simulations in order to further develop and validate the simulation method.

The study is a sub-study (WP3.4) in the TITA consortium project coordinated by the University of Turku and funded by the Strategic Research Council at the Academy of Finland.  The project aims, among other things, to evaluate the impacts of the initial deductible, which was introduced in 2016, analysed by patient groups and socio-demographic factors.

The impact of a reference pricing system and stepwise discounted prices on the prices of generic medicines

Promotion of generic substitution and increased price competition are widely used methods for the purpose of containing the rise in medicinal costs. In Finland, like many other European countries, attempts have been made to indirectly reduce the prices of generic medicines by means of generic substitution and reference pricing.  Austria is an example of a country where the government directly influences the prices of generic medicines. In Austria, the price of the first generic product must be at least 48% lower than the price of the original medicinal product, and the price of the second generic product 15% lower than the price of the first generic product.

The study aims to compare the volume of generic products and the prices of generic vs. original products in Finland and Austria. The study is jointly carried out in cooperation with the WHO Collaborating Centre for Pharmaceutical Pricing and Reimbursement Policies unit in Vienna, Austria.

Use of ADHD medication in the Nordic countries

In 2007, the frequency of the use of ADHD medicines varied considerably across the Nordic countries. In Finland, the use was the least. According to preliminary information, it appears that the use of ADHD medicines has rapidly expanded in countries where they were previously used to a limited extent. The purpose of the study is to compare the frequency and forms of use of ADHD medicines in the Nordic countries in 2007–2012.  The study is a collaborative project involving Kela in Finland, the Norwegian Institute of Public Health, the Southern University of Denmark, the University of Iceland, and the Karolinska Institute in Sweden.

Medicine costs in integrated social and health services – Case EKSOTE

The study aims to evaluate, within the South Karelia Social and Health Care District (Eksote), how the integration of social and health services and the transfer of the responsibility for the provision of the services from municipalities to a larger region would affect the medicinal and health care expenditure within the region. The study also analyses the medicinal costs of different population groups using social and health services. Additionally, the analysis concerns the transfer of the responsibility for medicinal costs to a wider social and health service region and the subsequent effects on the medicinal costs across the different service user groups.

The study is related to the work of a taskforce appointed by the Ministry of Social Affairs and Health to investigate the multi-channel funding of health care services.

Long-term use of sedatives and hypnotics in Finland

Sedatives (tranquilisers) and hypnotics (sleeping pills) are among the most commonly used medicines in Finland.  According to the treatment recommendations, these medicines should only be prescribed for short-term use of no more than a few weeks because of their harmful effects. Nevertheless, their long-term use is common. This register-based study investigates the development of long-term use of sedatives and hypnotics in Finland and associated factors.

The study is being implemented as a joint research project by Turku University Hospital, Kela Research, the Universities of Turku and Helsinki, and the Niuvanniemi Hospital. The data sources include several of Kela’s benefit registers as well as data from other registers.

From Kela Research, Leena Saastamoinen, Annamari Tuulio-Henriksson and Terhi Kurko participate in the project.

Sickness benefit recipients and changes by population groups and costs in Finland in 1990–2014

Absences due to illness are known to predict a likelihood of long-term work disability. However, there is very little researched knowledge on the recipients of sickness benefits, as provided by Kela, and trends across various population groups. 

The aim of this study is to analyse changes in the use of sickness benefits paid by Kela in 1990– 2014 in terms of certain essential population groups, various regions and different diagnostic groups.  The study will show which groups have seen positive development and which groups have a need for additional activities to promote work ability and to reduce and shorten periods on sickness benefits. The study will also address the costs of sickness benefit periods.

The project is being implemented in 2015–2017.

Impacts of rehabilitation changes on the customer (Muutos project).

The project aims to investigate the impacts and consequences experienced by customers due to the changes in the rehabilitation services provided by Kela. The project is comprised of several sub-studies focusing on different forms of rehabilitation or benefits. The underlying factors include changes in legislation or reforms based on the results of development work. The study involves the investigation of the implementation of rehabilitation services in a situation where the contents, activities or conditions related to a particular service or benefit have changed or where a completely new service has been created. The research focuses on the customer perspective: Is the rehabilitation timely and appropriate for the person receiving it? The purpose is to produce knowledge that is applicable to the development, steering and advocacy work within the field of rehabilitation.

The project is being implemented over the period of 1 May 2015 - 31 December 2019, financed with development funds in accordance with the law (KKRL § 12) and coordinated by Kela Research.

Multimodal neuropsychiatric family rehabilitation evaluation study

Kela contributes, for its part, to the well-being of families with children by supplementing the public health care services. In terms of mental and behavioural disorders among children and adolescents (aged 5–15 years), Kela focuses on the development and research of multimodal family rehabilitation.

During 2010–2018, two development projects are underway in Kela, one concerning the multimodal family rehabilitation (family intervention program LAKU) and the other concerning a teleservice model for family rehabilitation (Etä-LAKU).  Multimodal rehabilitation services are intended for families with a 5–12-year-old child who has been diagnosed with a neuropsychiatric disorder and possible other concurrent mental or behavioural disturbances.

The purpose of family rehabilitation is to support the child’s growth and development and coping with everyday life at home, day care and school as well as among friends and peers. The methods are selected to suit the age and target groups. For each family, the target is to reinforce the resources of the child’s parents and to support the mutual interaction among family members through family psychotherapy methods. A family rehabilitation process lasts 1–2 years.

The aim of the study is to evaluate the acceptance and suitability of multimodal family rehabilitation for the target group and assess the impacts of family rehabilitation on the well-being of the child and parents. The study has been registered in a public research register. The final report on the study will be published in the Kela Research Publications series in autumn 2018. The results will also be reported in national and international peer reviewed publications in the fields of medicine, social medicine and nursing science.

Rehabilitation to support the study and working life abilities of young adults suffering from neuropsychiatric disorders (Oma Väylä project)

In 2015, Kela initiated a project entitled Oma Väylä (‘Own Path’) with an aim to develop a group and individual rehabilitation model for young adults with neuropsychiatric disorders. The target group is comprised of young adults (aged 18–38 years) who have been diagnosed with Asperger’s syndrome or Attention Deficit and Hyperactivity Disorder (ADHD).

The Oma Väylä rehabilitation aims to reinforce and develop the study abilities, working life skills and everyday life management skills of young adults with a neuropsychiatric disorder.  Social skills are trained within everyday environments, such as home, school or the workplace. The 18-month-long rehabilitation process is implemented by a multiprofessional team, including a work coach who serves as a special worker, and also a working life specialist. The project supports, for its part, the realisation of the Youth Guarantee, which aims to advance young persons’ placement in education or the labour market and to prevent marginalisation or prolonged unemployment.

As part of the project, an evaluation study is being conducted by the National Institute for Health and Welfare (THL), jointly with Kela Research, to assess the aspects of development and impact.  In terms of development, the study aims to collect data on the process of seeking rehabilitation, the implementation of group rehabilitation, the integration of rehabilitation into everyday life and the motivation of rehabilitees. Observation and other qualitative methods are used as research methods. Data concerning the efficacy of the rehabilitation model and the success of collaboration with stakeholders will be collected through questionnaires and interviews among rehabilitees, service providers and interest groups.

The research project covers the years 2015–2018 and its results will be reported in national and international publications.

Implementation of Kela’s rehabilitation psychotherapy after the legislative change in 2011

At the start of 2011, the provision of rehabilitation psychotherapy became a statutory responsibility of Kela, instead of being a discretionary service. The change means, in practice, that the number of rehabilitees shall no longer be limited by the appropriations tied to a particular budget year. The criteria for receiving rehabilitation psychotherapy are mostly the same as earlier. The study population is comprised of the applicants and recipients of rehabilitation psychotherapy in 2011 and 2012, and the aim is to compare the situation after the legislative change to the situation before the change. On the basis of register data, we examine if the increase in psychotherapies is reflected as changes in the distributions of the demographic factors, occupation, diagnoses, psychotropic medication and sickness allowances among the rehabilitees, as compared to the situation before the amendment of the law.  Another aim of our research is to examine the labour market activity of the recipients of the statutory psychotherapy before the rehabilitation, at its start and end, as well as during a two-year follow-up. We also investigate the implementation of rehabilitation psychotherapies of varying duration and the refusal and granting decisions concerning rehabilitation psychotherapies.

The research project covers the years 2016–2017 and its results will be reported in national and international publications.

Microsimulation methods are used to simulate and analyse the effects of legislation on household transfers and taxes. Microsimulation is useful both in drafting legislation and as a tool of tax and social security research. For example, it allows the researcher to examine long-term trends in social security legislation and to test the impact of different hypothetical changes in legislation on household incomes.

The Research Department will participate in the design of a new simulation model, which will be maintained by Statistics Finland. The Department is already involved in the updating and maintenance of the JUTTA microsimulation model.

Cooperation partners: Statistics Finland, Ministry of Finance, Ministry of Social Affairs and Health, National Institute for Health and Wellbeing, Government Institute for Economic Research, Labour Institute for Economic Research, Library of Parliament's Information Service.
