- Cohort
- Follow Up
- All participants of the Population Study are followed-up each time they reach the age of an older cohort at base time, i.e. at the age of 66, 72, 78, 81, 84, 87, 90, 93, 96 and 99+ years. Participants in the Care System Study are followed up each time the decision for assistance is re-evaluated. This should be done at least once a year.
- Supplementary Information
- For the Population Study, a panel of elders is taken from 10 different age cohorts, beginning at the age of 60 up to 96 years with a 6-year interval between the younger cohorts (up to 78 years) and a 3-year intervals thereafter. New cohorts of 60- and 81-year olds joined the study in 2007-2010, and 2014-2016, respectively. The Care System Study is a systematic, longitudinal, individually-based collection of data of all persons 65+ years living in the area with their registration connected to assistance decisions.

Data Collection Event
Data were collected each year in the spring. All contacts between older persons and the care system in the involved area were recorded. It concerned the operations of long-term care services system including volume and character of services provided in the relation to disability and other factors influencing needs.
Data collected cover the person's functional ability in terms of ability to perform personal (PADL) and instrumental activities of daily living (IADL), cognitive functioning using the Berger scale, special health complaints or needs (persistent pain, dizziness, ulcers, anxiety, in need of constant monitoring), living circumstances and conditions in terms of adaptation of housing to functional problems, access to informal care or privately organized or paid care, and details concerning public health care and services according to the Social Services Act and/or the Health and Medical Services Act. Additional information concerning the use of hospital care and out-patient care can be obtained through the county council administrative registers. Municipality registers provide data on personal income and co-payment for care services.
During 2012, the problem area of pain has been updated and an in-depth analysis was conducted on the specific housing. In addition, a new instrument, QUALID, was introduced for measuring quality of life.
