Acute psychiatric admissions from an out-of-hours Casualty Clinic. How do referring doctors and admitting specialists agree?
Deraas, Trygve Sigvart; Giæver, Anton; Hansen, Vidje; Olstad, Reidun (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-03-29)Background: Over the last decades there has been an increasing pressure on the acute psychiatric wards in Norway. The major contributor to psychiatric acute admissions at the University Hospital of North Norway in the city of Tromsø in 2001 was the GP-based Tromsø Casualty Clinic, only open out-of-hours. We explored all acute psychiatric referrals from Tromsø Casualty Clinic in 2001. The purpose ... -
Associations between Primary Health Care- and Hospital Utilization among Elderly People in Norway
Deraas, Trygve Sigvart (Doctoral thesis; Doktorgradsavhandling, 2013-12-11)Summary Background: Geographical variations in health-care utilization in many countries have been an area of debate. Health-care supply factors, population and/or environmental need factors might explain the so-called small-area variations (SAVs). Demographic forecasts indicated a significant increase in the elderly population over the next few decades, with a resulting increased need for ... -

Changes in adiposity, physical activity, cardiometabolic risk factors, diet, physical capacity and well-being in inactive women and men aged 57-74 years with obesity and cardiovascular risk – A 6-month complex lifestyle intervention with 6-month follow-up
Hopstock, Laila Arnesdatter; Deraas, Trygve Sigvart; Henriksen, André; Martiny-Huenger, Torsten; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-25)A key challenge in lifestyle interventions is long-term maintenance of favorable lifestyle changes. Middle-aged and older adults are important target groups. The purpose of this analysis was to investigate changes in adiposity, physical activity, cardiometabolic risk factors, diet, physical capacity, and well-being, in inactive middle-aged and older women and men with obesity and elevated cardiovascular ... -
Complex lifestyle intervention among inactive older adults with elevated cardiovascular disease risk and obesity: a mixed-method, single-arm feasibility study for RESTART—a randomized controlled trial
Deraas, Trygve Sigvart; Hopstock, Laila Arnesdatter; Henriksen, André; Morseth, Bente; Sand, Anne-Sofie; Njølstad, Inger; Pedersen, Sigurd; Sagelv, Edvard Hamnvik; Johansson, Jonas; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-27)Background - Physical inactivity and obesity are global public health challenges. Older adults are important to target for prevention and management of disease and chronic conditions. However, many individuals struggle with maintaining increased physical activity (PA) and improved diet. This feasibility study provides the foundation for the RESTART trial, a randomized controlled trial (RCT) to test ... -
Does long-term care use within primary health care reduce hospital use among older people in Norway? A national five-year population-based observational study
Deraas, Trygve Sigvart; Berntsen, Gro; Hasvold, Toralf; Førde, Olav Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Population ageing may threaten the sustainability of future health care systems. Strengthening primary health care, including long-term care, is one of several measures being taken to handle future health care needs and budgets. There is limited and inconsistent evidence on the effect of long-term care on hospital use. We explored the relationship between the total use of long-term care within public ... -
High referral rates to secondary care by general practitioners in Norway are associated with GPs' gender and specialist qualifications in family medicine, a study of 4350 consultations
Ringberg, Unni; Fleten, Nils; Deraas, Trygve Sigvart; Hasvold, Toralf; Førde, Olav Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Referral rates of general practitioners (GPs) are an important determinant of secondary care utilization. The variation in these rates across GPs is considerable, and cannot be explained by patient morbidity alone. The main objective of this study was to assess the GPs’ referral rate to secondary care in Norway, any associations between the referral decision and patient, GP, health care characteristics ... -
Is a high level of general practitioner consultations associated with low outpatients specialist clinic use? A cross-sectional study

Practice variation in surgical procedures and IUD-insertions among general practitioners in Norway – a longitudinal study
Pahle, Andreas; Sørli, Daniel; Kristiansen, Ivar Sønbø; Deraas, Trygve Sigvart; Halvorsen, Peder Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-21)Background: Studies of Primary Health Care (PHC) reveal considerable practice variations in terms of the range of services provided. In Norway, general practitioners (GPs) are traditionally expected to perform IUD-insertions and several surgical procedures as a part of comprehensive PHC. We aimed to investigate variation in the provision of surgical procedures and IUD-insertions across GPs and ... -
Succeeding with prolonged usage ofconsumer-based activity trackers in clinicalstudies: a mixed methods approach
Henriksen, André; Sand, Anne-Sofie; Deraas, Trygve Sigvart; Grimsgaard, Sameline; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-27)<i>Background</i> - Lack of physical activity (PA) is a risk factor for death and non-communicable disease. Despite this, more than one fourth of adults worldwide do not follow PA guidelines. As part of a feasibility study to test a complex intervention for increasing PA, we included a consumer-based activity tracker (AT) as a tool to measure PA outcomes and to track heart rate during exercise ... -
Use of Health care in the main area of Sami habitation in Norway : catching up with national expenditure rates
Gaski, Margrete; Melhus, Marita; Deraas, Trygve Sigvart; Førde, Olav Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)For many years political and professional concerns have centred on the health service access of Norway’s modern Indigenous Sami people. Thirty years ago, a study determined that a low rate of health expenditure on Sami patients had lead to inferior health services for the Sami people, with their average consultation rate 6 times lower than the Norwegian national average. Since 1980, there have been ...
