RESUMO
Objective:To explore the effectiveness of Acute Care of the Elderly(ACE)model and its existing problems in the clinical practice for older adults with acute clinical conditions.Methods:Using the random number table method, a random number sequence was generated, and the patients admitted to the Department of Geriatrics of Shenzhen Nanshan Hospital due to acute diseases From January 2019 to September 2021 were enrolled in the ACE model intervention group(160 cases)and the control group(77 cases)in a 2: 1 ratio.The inclusion criteria were based on disease severity, frailty assessment, and activity of daily living(ADL)assessment.The intervention time was 1-3 weeks.Outcomes of the patients include ADL, hospitalization days, hospitalization expenses, drug proportion, human resource investments, adverse events, 30-day readmission rate, and 1-year mortality.Results:There were no significant difference in baseline indicators such as frailty index and ADL score between the two groups at admission.The ADL score(Barthel index)of the ACE group was significantly improved compared with the control group at discharge(81.71±14.23 vs.70.9±23.89, P<0.001)and at 30 days after discharge(85.84±15.25 vs.68.29±30.91, P<0.001). The hospital cost[(12 735.81±6 541.41)￥ vs.(16 391.54±12 962.34)￥, P=0.002], drug proportion(21.34% vs.28.93 %, P=0.036)and 30-day readmission rate(13.1% vs.23.4%, P=0.037)of the ACE group were significantly lower compared to the control group.The human resource input(32.97±6.72 vs.25.03±5.31, P=0.008)and patient satisfaction(98.23% vs.90.66%, P=0.031)in the ACE group were significantly higher than those of the control group.(4)The incidence of adverse events during hospitalization was significantly lower in the ACE group than in the control group in terms of aspiration(0.63% vs.20.8%, P<0.001), falls(0 vs.10.4%, P<0.001), incontinence dermatitis(0 vs.3.9%, P=0.033), and 1-year mortality(6.3% vs.24.7%, P<0.001). There was no significant difference in the average length of stay(8.98±4.25 vs.10.03±5.32, P=0.101), pressure sores(13.01±4.77 vs.13.27±4.89, P=0.364), DVT risk score(8.53±2.79 vs.8.89±2.76, P=0.340)and medical staff satisfaction(73% vs.80%, P=0.240)between the two groups. Conclusions:The ACE model helps to reduce the disability rate of elderly patients with frailty, adverse events during hospitalization, save drug costs, and improve patient satisfaction.It is worth promoting in geriatric practice, but its localization management details and processes still face many challenges.
RESUMO
Objective To evaluate the usefulness of speckle tracking imaging(STI) for assessment of left ventricular(LV) and right ventricular (RV) functions in patients with isolated disease of right coronary artery.Methods 45 cases were diagnosed as single right coronary lesions given echocardiography,30 cases had chest pain but coronary angiography had not seen the obvious narrow as a comparison.The twodimensional loop-cinec were obtained in apical 4-chamber view,apical 2-chamber view and long axis of LV view.Eighteen segments of LV longitudinal peak systolic strain,global peak systolic strain of each view and three segments of RV free wall were measured by two-dimensional strain software.Results In the patients who had right coronary lesions but did not happen myocardial infarction,the strain(S) values in the base,mid and apex segmental of LV post wall,the base and mid segmental of LV inferior wall and the base and mid segmental of LV septum were significantly lower( P ＜0.05).The S values in the mid segment of RV free wall was lower( P ＜0.05).In the patients who had right coronary lesions and myocardial infarction,the S values in the base,mid segmental of LV antsept,the apex segmental of LV anterior wall,the base,mid and apex segmental of LV post wall,the base and mid segmental of LV inferior wall and the base and mid segmental of LV septum were significantly lower( P ＜0.05).The S values in the mid and apex segments of RV free wall were lower ( P ＜0.05).And the LV global longitudinal strains were lower in the two groups (P ＜0.05).Conclusions STI is a new and useful technology for assessment ventricular functions in patients with isolated disease of right coronary artery,and there are multiple segments impaired.
RESUMO
ObjectiveTo evaluate the usefulness of speckle tracking imaging(STI) for assessment of systemic right ventricle (RV) function in patients with acute inferior myocardial infarction(MI) and the changes 7 days after percutaneous coronary interventions(PCI).MethodsTwo-dimensional imaging at the four chamber view was obtained with tracing of the entire RV endocardial border in 44 patients with acute inferior MI and 50 healthy volunteers.Peak longitudinal systolic strain and strain rate (S,SR)in six RV segment included the basal,mid,and apical segments of the RV free wall and septum.And thirty patients reexamined 7 days after PCI.ResultsThe S values in the base and mid segmental of RV free wall and all segments of right septum were significantly lower in patients with acute inferior MI( P ＜0.05).But the SR values only decreased in mid segment of right septum.Except the apical parts of RV free wall and right septum,the S values of others segmental were significantly improved( P ＜0.05) 7 days after PCI.But the SR values had no changes( P ＞0.05).ConclusionsSTI is a new and useful technology for assessment of RV function in acute inferior MI and the RV function can be improved by emergency PCI.
