Improving the vulnerable hospital discharge process among older people has been in focus for decades. The economic impact and ease of measurement of all-cause hospital readmission rates have questioned whether they are reducible. This review aimed to identify the efficiency of follow-up home visits after hospital discharge by district nurses in coordination with general practice. Six settings in Denmark have been evaluated in different controlled designs. Results are inconsistent and inconclusive due to selection bias and methods chosen. Targeting and management organisation need further research.
