Sickness absence, disability pension and economic situation after a spontaneous subarachnoid haemorrhage among people of working age: a Swedish longitudinal nationwide cohort study

OBJECTIVES: The aim was to describe the course of sickness absence (SA), disability pension (DP) and work-related economic situation defined as earnings (EA) and disposable income (DI), after spontaneous subarachnoid haemorrhage (SAH). Associations of SA, DP, EA and DI with demographic factors were also studied. DESIGN: A longitudinal cohort study of all 1932 people in Sweden who in January 2005 to December 2010 had a first time SAH when aged 17 to 64 years and survived during the 3-year follow-up. Microdata from four nationwide administrative registers were used. MAIN OUTCOME MEASURES: Primary outcome was the presence of SA and DP and how this changed during the study period of 5 years (the year before, the year of SAH and the following 3 years). The secondary outcome was the development of the income variables EA and DI. Demographic factors analysed were sex, age, source of bleeding, country of birth, family situation, educational level and type of living area. RESULTS: The year before the SAH, 7.9% of women and 4.6% of men had some SA registered (p<0.004). A model consisting of female sex, higher education and living single predicted having SA that year. At the end of the follow-up, 39.2% of women and 28.3% of men had SA and/or DP (p<0.0001). A model consisting of female sex, living in a village/ rural area and having a defined bleeding source for the SAH was predicting having SA and/or DP at end of follow-up. The levels of EA decreased, while DI increased during follow-up and were at the end of follow-up associated with age, sex, type of living area, country of birth, educational level and family situation. The women’s EA was lower than the men’s during all years. CONCLUSIONS: SAH influenced future SA, DP, as well as EA. Both SA, DP and the economic variables studied were predicted by models including sex.
