Effects Of Hypophosphatemia On The Ability Of Daily Life Of In-patients With Advanced Age

Objective Discusses the effect of Hypophosphatemia on the ability of daily life of senile inpatients.Methods Part 1:Case data of 1517 patients 0f 60~90 years old who were admitted to our hospital from July 2013 to October 2015 were collected for retrospective analysis. The x2 test was used for analysising if the distribution of hypophosphatemia was different between different age groups, and t test was used for analysising whether the average age was different between different Blood phosphorus levels groups.Part 2:Collected from July 2013 to October 2015, admitted to our hospital in the medical records of 319 patients over the age of 75 years were retrospectively analyzed, using single factor analysis of chi-square,using logistic regression to multi-factor analysis, explore the gender, age,Spouse situation, Cumulative Illness Rating Scale for Geriatrics(CIRS-G), NRS2002 nutritional assessment, especially the blood phosphorus levels on ability of daily life(ADL) classification.Results Part 1 :(1) The constituent ratio ofhypophosphatemia of60 ~ 90 years old hospitalized patients is 16.35% in our geriatric medicine at a rough estimate.(2) 76 ~ 90 years old group than The60 ~ 75 years old, low phosphorus hematic disease distribution is higher, the difference was statistically significant(P<0.05).(3) T test analysis showed that low phosphorus group than the blood phosphorus normal group, the average age is older, the difference was statistically significant(P<0.05).Part 2:(1) Single factor analysis showed that 81 ~ 90 years group than the 75 ~ 80 years old, CIRS-G score heavy group than the low and moderate, low phosphorus group than the normal blood phosphorus,widowed group than spouses living, NRS2002 nutrition assessment severe group than the mild, ADL disorder in patients with more serious,the difference had statistical significance(P < 0.05).(2) The multi-factor analysis showed that low phosphorus concentration, age and CIRS-G serious are risk factors for elderly patients ADL severe obstacles, spouses living for its protective factors, odds ratio and 95% CI 2.858 [1.322,6.180], 3.544 [1.561, 8.046],2.862 [1.378, 5.945], 0.373 [0.172, 0.809](P< 0.05).Conclusions Part 1:In hospitalized elderly patients, the older patients are more likely to occur hypophosphatemia.Part 2:Hypophosphatemia, age, CIRS-G serious are risk factors of senile inpatients ADL disabilities, and spouses living is protective factors.
