This study described the prevalence and levels of multimorbidity among patients receiving physician\u2010led home care in Japan and examined the association between multimorbidity level and emergency home visits.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A multicenter cross\u2010sectional study was conducted in 2024 using physician\u2010completed questionnaires derived from medical records. Multimorbidity was defined as the presence of two or more chronic conditions. Based on prior literature, multimorbidity level was categorized as low (2\u20133 conditions), medium (4\u20135 conditions), or high (\u2265\u20096 conditions). The primary outcome was the occurrence of an emergency home visit within the preceding month.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 506 included patients, 94.7% met criteria for multimorbidity, and 13.2% required an emergency home visit. In multivariable generalized linear mixed\u2010effects models with a logit link, higher multimorbidity levels were independently associated with increased odds of emergency home visits, with adjusted odds ratios of 2.16 (95% CI, 1.09\u20134.31) for the medium\u2010level group and 2.72 (95% CI, 1.19\u20136.19) for the high\u2010level group compared with the low\u2010level group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Multimorbidity was highly prevalent among Japanese patients receiving home care, exceeding prior domestic estimates while aligning with international reports. Higher levels of multimorbidity were associated with an increased likelihood of emergency home visits, suggesting that assessment of multimorbidity level may, if confirmed in future studies, inform risk stratification and policy planning for home\u2010based care services.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial
