| ObjectiveThrough investigation the change of uncertainty in illness and BNP in elderly patients with chronic heart failure before and after to give targeted information to support, Definite the function of targeted information in clinical intervention, providing the evidence for nurses to conduct health education, decrease the uncertainty sense in elderly patient with CHF, reduce BNP, lower down the process of disease, prolong life, improve the life quality.Methods80cases of patients with chronic heart failure of Shandong Qianfoshan Hospital, is the object of study, and press the admission randomly divided into control group and observation group40cases each. The day of admission, survey of two groups of patients with Self-prepared heart failure knowledge test, according to the findings of the questionnaire, doctors and nurses to develop information support for the observation group. The control group patients which only accept nurses provide regular health guidance; in addition to receive regular health education guidance, the experimental group patients also receive targeted information support. In the day of admission and one day before discharge, to investigate the two groups of patients, the level of uncertainty in illness with Uncertainty in Illness Scale, and fluorescence immunoassay test method for the determination of plasma BNP levels, the statistical comparison between the two groups, to determine the effects of the targeted information on reduction of uncertainty in illness and plasma BNP levels in elderly patients with chronic heart failure.Result1. Uncertainty in illness in elderly heart failure patients admitted to hospital belongs to the high levels. The level of uncertainty in illness of elderly patients with chronic heart disease in the control group at discharge decreased (P<0.01), difference was statistically significant. The level of uncertainty in illness of elderly patients with chronic heart failure in the observation group admitted to hospital discharge decreased significantly (P<0.01), difference was statistically significant.2. On the day of the admission, a sense of uncertainty of elderly patients with chronic heart failure, compared with the observation group and control group, the difference was not statistically significant (P>0.05).The uncertainty sense of the control group is lower observation group in elderly patients with chronic heart failure at discharge (P <0.05),difference was statistically significant.3. After conventional treatment and care of, patients with BNP decreased, the difference was statistically significant (P<0.05).After targeted information support, the elderly patients with heart failure, BNP was decreased, the difference was statistically significant (P<0.05).4. On the day of the admission, the BNP of elderly patients with chronic heart failure, compared with the observation group and control group, the difference was not statistically significant (P>0.05). BNP is lower in elderly patients with CHF given targeted information support compared with the patients given routine health instruction at discharge (P<0.05), difference was statistically significant.5. The pearson correlation coefficient between the BNP and uncertainty in illness score of CHF was0.5101,(P<0.01) it was statistically significant, Explain a positive correlation between the BNP and uncertainty in illness of CHF, the results showed that elevated BNP levels, the uncertainty in illness score of patients gradually increased.6. An average score of the uncertainty in illness was83.92±6.44in heart failure patients with heart function Ⅱ, average score of cardiac function Ⅲ patients with heart failure uncertainty in illness was92.97±6.23,the average uncertainty in illness score of cardiac function IV patients with heart failure was102.92±5.34. Homogeneity of variance test showed (P>0.05), Uncertainty in illness score between groups of different cardiac function analysis of variance showed difference was statistically significant (F=63.46, P<0.01).7. In elderly patients with heart failure, the correct awareness of digoxin on security was11.25%, the correct rate of β_blockers on heart rate was6.25%,the correct rate of Insisting on taking was6.25%,the correct rate of difficulty in breathing, weakness was3.75%, fluid retention was11.25%, electrolyte imbalance was11.25%, salt intake, activities for training was6.25%; the correct rate of prevention was93.75%, the treatment of primary disease was93.75%prescribed medication on time was56.25%, Smoking and alcohol cessation was71.25%, keeping the mood steady was88.75%.Conclusion1. Compared with conventional health education targeted information support can significantly decrease the uncertainty in illness scale and the BNP among elderly patients with chronic heart failure. So targeted information support should be strengthen in aged patients with CHF.2. Uncertainty in illness was high in patients with high BNP and poor cardiac function. Prompted the nursing staff should pay particular attention to the uncertainty in illness of patients with high BNP levels and poor cardiac function in the work.3. Elderly heart failure patients on adverse drug reactions and precautions, fluid retention, electrolyte imbalance, salt intake, exercise training, correct awareness was lower, health education should strengthen on these aspects. |
