Multimorbidity in most Japanese home care patients

Tsukuba, Japan—As Japan's population ages, more older adults are receiving home-based medical care, where physicians regularly visit patients who have difficulty visiting clinics or hospitals. Although multimorbidity has long been common among home care patients, few studies have assessed its prevalence in this population.

The researchers addressed this gap by conducting a multicenter study involving 506 adults receiving physician-led home care from medical facilities in Tokyo and Ibaraki Prefecture. Using information obtained from medical records, the team assessed the number of chronic conditions for each patient and examined the association between multimorbidity level (the number of chronic conditions present) and the occurrence of emergency home visits (unscheduled physician visits requested due to sudden changes in a patient's condition).

The study found that 94.7% of patients had multimorbidity, defined as the presence of two or more chronic conditions. More than half of the participants (57.1%) had four or more chronic conditions. Overall, 13.2% of patients required at least one emergency home visit in the previous month.

The researchers further categorized patients according to multimorbidity level. Compared with patients who had two or three chronic conditions, those with four or five conditions, and especially those with six or more, were significantly more likely to require emergency home visits.

These findings suggest that a simple count of chronic conditions may help healthcare professionals identify home care patients who are at increased risk of sudden health deterioration and may benefit from more proactive care planning.
