Clinical trials

The primary aim of this study is to investigate the effects of reducing weekly working hours among employees working night shifts regularly from 38 hours 15 minutes to 36 hours on payroll-based, objective working-hour characteristics, sickness absence, and workforce retention. The secondary aim is to investigate experiences of promoting and hindering factors related to the working-hour reduction, its implementation process, and perceived benefits and challenges. The working-hour reduction will be implemented in three Finnish wellbeing services counties with different starting dates, the first being in late September 2026 and the latest in early 2027. The working-hour reduction has been agreed upon by the parties to the collective agreement for Finnish public social and health care. Thus, intervention is a so-called natural experiment in a real-life setting. The effects of the intervention will be evaluated using a quasi-experimental design with staggered, non-randomized implementation across participating counties. Administrative, payroll-based, employer-owned working-hour data, including records of sickness absences without any medical or health information and other absences (including unpaid, education, and childcare), will be used to compare changes before and during the intervention among work units participating in the working-hour reduction. The investigation will also utilize matched work units that do not participate in the reduction (i.e., intervention) as control units (i.e., continuing standard working-hour arrangements).

The aim of this randomized controlled trial (RCT) is to investigate whether cognitive job accommodation intervention enhances return to work, work ability and performance after ischemic stroke in working-age population. The main questions are: * Does the cognitive job accommodation intervention affect absenteeism and presenteeism after stroke? * Does the intervention affect work ability and perceived cognitive and emotional difficulties at work? * Does the intervention decrease mental strain, fatigue and negative mood symptoms after return to work? * Does the intervention affect life satisfaction among the stroke patients returning to work? Researchers will compare the intervention group to a control group returning to work after stroke with current healthcare practices and work procedures. Participants: * At baseline, 6 and 12 month follow-up web-based questionnaires and cognitive tests are administered. * At 3 month follow-up participants fill in Brain Work Questionnaire (BWQ) that measures cognitive demands and difficulties at work.
