Aim: To examine the actual conditions of older patients receiving home medical care after hospitalization over a period of 2 years in Japan., Methods: The study population included 102 participants, aged ≥65 years, receiving home medical care, who consented to participate in the Osaka Home Care Registry (OHCARE) study in Japan over a period of 2 years. We investigated the actual conditions for returning home after hospitalization., Results: The median age of the 102 participants was 84 years, and 61 (59.8%) were women. In the group that returned home, 42 (55.3%) of the respondents desired to recuperate in a familiar place, as in advanced care planning (ACP). During the 2-year follow-up period, the group that did not return home had significantly more deaths. A multivariate analysis showed the association in the presence of ACP (odds ratio: 4.72, 95% confidence interval: 1.60-13.86) and cardiac disease (odds ratio: 0.25, 95% confidence interval: 0.08-0.76). The lack of ACP in the medical records when the patient was admitted to the hospital may have prevented the return home., Conclusion: In older patients who had difficulty returning home after hospitalization, the lack of ACP in home medical care may have been an influencing factor. ACP could help continue with home medical care. Geriatr Gerontol Int 2024; 24: 320-326., (© 2024 Japan Geriatrics Society.)

Some studies reported that excessive blood pressure (BP) control was not appropriate for older people, especially from the viewpoint of quality of life and maintaining sufficient blood flow for tissue perfusion. However, the lower limit of the target BP is still unclear, and there has not yet been a sufficient consensus. Therefore, we investigated the associations of BP levels with clinical events in older patients ~85 years old receiving home medical care. A total of 144 patients were included, who were followed for longer than 3 months in the Osaka Home Care Registry study, a prospective cohort study targeting older patients receiving home medical care in Japan. BP levels were divided into lower and higher groups based on the average systolic blood pressure (SBP). The main outcomes were clinical events, including hospitalizations, falls, and deaths during follow-up. As a result, the hospitalization rate in the SBP below 124 mmHg group was significantly higher than that in the SBP over 124 mmHg group. When comparing the clinical events between the two groups only in participants with hypertension, the same results were obtained. Furthermore, in Cox proportional hazards regression models adjusted by age, sex, and current diseases, the SBP below 124 mmHg group showed a significantly higher rate of required hospitalization (hazard ratio: 7.25, 95% confidence interval: 1.79-29.45). Thus, in older and very frail patients requiring home medical care, an SBP level below 124 mmHg could be a predictive marker of clinical events leading to hospitalization.

Aim: We investigated seasonal variations in blood pressure (BP) and factors related to these variations among older patients receiving home medical care., Method: A total 57 patients ≥ 65 years old receiving home medical care who participated in the Osaka Home Care REgistry study (OHCARE), a prospective cohort study, were included. We investigated the seasonal patient characteristics and variations in the BP. In addition, to determine the influence of seasonal variations in the systolic blood pressure (SBP) on the occurrence of clinical events (hospitalization, falls and death), we classified patients into larger- and smaller- change groups based on the median seasonal variations in SBP., Result: About 60% of subjects were very frail or bedridden. The mean BP was higher in winter than in summer (124.7±11/69.5±7 vs.120.5±12/66.9±8 mmHg) (P< 0.01). On comparing the characteristics of the two groups with larger and smaller changes in the SBP, the group with large BP changes had a significantly lower BP in summer than the group with small BP changes. In addition, the incidence of "hospitalization" was significantly higher in the group with large BP changes than in the group with small BP changes (P = 0.03)., Conclusion: The present study revealed that there were seasonal changes in the BP in older patients receiving home medical care. It was also suggested that seasonal changes in the BP might be associated with the risk of hospitalization events. Given these BP variations, doctors and visiting nurses should be alert for systemic abnormalities, especially in frail patients receinving home medical care.
