Duration of homelessness and its relationship to use of hospital and emergency department services in Helsinki, Finland.

Aims: Homelessness is associated with poor health outcomes and increased use of hospital and emergency department (ED) services. Little is known about the duration of homelessness in relation to health care service use. The aim of this study was to examine the use of hospital and ED services among the homeless in Helsinki, Finland, and for the first time, to examine the relationship between service use and duration of homelessness. Methods: Six hundred and eighty-three persons staying at least one night in a shelter between September 2009 and September 2010 were followed until the end of 2014. Using negative binominal regression analysis we calculated the use of hospital and ED services and compared the use with that of a matched control group (N = 1361). We also analyzed service use in relation to the time spent homeless during follow-up. Results: The mean time spent homeless during the follow-up was 8.5 months, one third was temporarily homeless (less than 2% of the follow-up time), but recurrent episodes of homelessness were also common. The study group's incidence rate ratios for medical-surgical hospital days was 6.23 (95% CI: 4.73 to 8.21), for psychiatric hospital days 43.11 (95% CI: 23.02 to 80.74) and for ED visits 10.21 (95% CI: 8.77 to 11.90), compared with controls. The number of medical-surgical hospital days and ED visits/person-year increased as homelessness was prolonged, but the pattern was opposite for psychiatric hospital days. Conclusions: Homeless persons are heavy users of hospital and ED services, and there is also increased use among those temporarily homeless.

Morbidity and housing status 10 years after shelter use-follow-up of homeless men in Helsinki, Finland.

Background: Homelessness is associated with increased mortality, morbidity and social difficulties and periods of homelessness are sometimes prolonged or repeated. However, there are no long-term follow-up studies focusing upon housing status among homeless people. The aim of this study was to examine morbidity and housing outcomes and to identify factors predicting being independently housed 10 years after shelter use. Methods: By combining data from several registers we followed all 552 homeless men who stayed in shelter in Helsinki during 2004 and determined their housing situation and morbidity 10 years later. Their situation was compared with an age-matched control group from the general population (N = 946). Using logistic regression analysis, we assessed the predictive effects of socioeconomic factors and health service use at baseline on becoming independently housed. Results: By the end of the follow-up 52.0% of the formerly homeless study group had died, compared with 14.6% of the controls. At 10 years, 6.0% were independently housed, 37.5% lived in supported housing and 4.5% were still or again homeless. Psychiatric disorders, including substance use disorder, were present in 77.5% of the homeless, compared with 16.1% among the controls. Being married (OR 8.3, 95% CI 3.0 to 23.2) and having less than four shelter nights in year 2004 (OR 9.1, 95% CI 2.7 to 30.8) strongly predicted being independently housed 10 years later. Conclusions: Homeless staying in shelters have high mortality and morbidity and most of those surviving, are in need of support in their everyday lives even years after the shelter period.

Mental disorders and the use of primary health care services among homeless shelter users in the Helsinki metropolitan area, Finland.

BACKGROUND: Homelessness is associated with increased morbidity, mortality and health care use. The aim of this study was to examine the role of mental disorders in relation to the use of 1) daytime primary health care services and 2) after hours primary health care emergency room (PHER) services among homeless shelter users in the Helsinki Metropolitan Area, Finland. METHODS: The study cohort consists of all 158 homeless persons using the four shelters operating in the study area during two selected nights. The health records were analyzed over a period of 3 years prior to the sample nights and data on morbidity and primary health care visits were gathered. We used negative binomial regression to estimate the association between mental disorders and daytime visits to primary health care and after hours visits to PHERs. RESULTS: During the 3 years the 158 homeless persons in the cohort made 1410 visits to a physician in primary health care. The cohort exhibited high rates of mental disorders, including substance use disorders (SUDs); i.e. 141 persons (89%) had a mental disorder. We found dual diagnosis, defined as SUD concurring with other mental disorder, to be strongly associated with daytime primary health care utilization (IRR 11.0, 95% CI 5.9-20.6) when compared with those without any mental disorder diagnosis. The association was somewhat weaker for those with only SUDs (IRR 4.9, 95% CI 2.5-9.9) or with only other mental disorders (IRR 5.0, 95% CI 2.4-10.8). When focusing upon the after hours visits to PHERs we observed that both dual diagnosis (IRR 14.1, 95% CI 6.3-31.2) and SUDs (11.5, 95% CI 5.7-23.3) were strongly associated with utilization of PHERs compared to those without any mental disorder. In spite of a high numbers of visits, we found undertreatment of chronic conditions such as hypertension and diabetes. CONCLUSIONS: Dual diagnosis is particularly strongly associated with primary health care daytime visits among homeless persons staying in shelters, while after hours visits to primary health care level emergency rooms are strongly associated with both dual diagnosis and SUDs. Active treatment for SUDs could reduce the amount of emergency visits made by homeless shelter users.

Mortality and causes of death among homeless in Finland: a 10-year follow-up study.

BACKGROUND: Homelessness is associated with increased mortality, and some predictors of mortality have been previously identified. We examined the overall and cause-specific mortality among homeless men in Helsinki and the associations of social background and health service use with mortality. METHODS: To assess cause-specific mortality in a competing risks framework, we performed a register-based, case-control study of 617 homeless men and an age-matched control group of 1240 men from the general population that were followed for 10 years between 2004 and 2014. Cox proportional hazards model was used to calculate HR for death and a competing risks model to calculate sub-HRs (sHR) for cause-specific death. RESULTS: During the follow-up, 45.0% of the homeless died compared with 10.5% of controls (HR 5.38, 95% CI 4.39 to 6.59). The risk of death was particularly elevated for the homeless aged≤50 years (HR 10.3, 95% CI 7.0 to 15.2). External causes caused 34% of the deaths (sHR 11.2, 95% CI 6.8 to 18.2), but also deaths from medical causes were common (sHR 3.6, 95% CI 2.9 to 4.6). Age and somatic hospitalisation were significant predictors of death both among homeless and controls. Educational attainment, marital status, employment and psychiatric hospitalisation were significant predictors of mortality among the controls, but not among the homeless. CONCLUSIONS: Homelessness is associated with a fivefold mortality compared with the controls, and especially homeless aged ≤50 years have an increased risk of death. Being homeless eliminates the protective effects of marriage, employment and education on mortality risk.
