Abstract:
Objective:To investigate the influence of potentially inappropriate medication (PIM) on emergency treatment or hospitalization events due to heart failure in elderly outpatients.Methods:The data of outpatient, emergency patient, and inpatient above 65 years old collected in Beijing Medical Insurance Affairs Management Center database from July 1, 2016 to September 30, 2016 were retrospectively analyzed. PIM in the outpatient western medicine prescription was identified using the 2015 Beers Criteria ?. PIM exposure was defined as at least one PIM was prescribed within 3 months and patients were divided into the PIM exposure and non-PIM exposure groups accordingly. Clinical outcome events were defined as experiencing emergency treatment or hospitalization events due to heart failure after ≥14 days of PIM exposure. Clinical characteristics in patients between the 2 groups were compared and the exposure of specific PIM (PIM with the 3 highest use frequency) in the PIM exposure group was described. Influencing factors of clinical outcome events were analyzed using logistic regression analysis. Results:A total of 506 214 patients were entered in the study, including 252 604 males (49.90%) and 253 610 females (50.10%), aged from 65 to 105 years with a median age of 74 (68, 80) years. Definition of PIM exposure was met in 192 740 patients (38.07%); clinical outcome events occurred in 249 patients, of which 131 patients (0.03%) received emergency treatment and 118 patients (0.02%) hospitalized due to heart failure. Incidences of emergency treatment and hospitalization due to heart failure in patients of the PIM exposure group were higher than those of the non-PIM exposure group [0.04% (78/192 740) vs. 0.02% (53/313 474), P<0.001; 0.04% (71/192 740) vs. 0.01% (47/313 474), P<0.001]. The 3 PIM that used most frequently were vasodilators, diuretics, and central nervous system drugs. Multivariate analysis showed that PIM exposure and use of vasodilators and central nervous system drugs had no significant effects on the occurrence of emergency treatment and hospitalization events due to heart failure, while age ≥75 years old and use of diuretics had significant effects. Compared with the 65-74 age group, the risk of emergency treatment for heart failure in patients of the 75-84 age group and ≥85 age group increased by 3.00 times ( OR=4.00, 95 %CI: 2.46-6.51) and 7.14 times ( OR=8.14, 95 %CI: 4.64-14.29), respectively, and the risk of hospitalization for heart failure increased by 1.33 times ( OR=2.33, 95 %CI: 1.52-3.57) and 2.59 times ( OR=3.59, 95 %CI: 2.03-6.36), respectively. Compared with patients without diuretics treatment, patients treated with diuretics had a 1.91-fold increase in the risk of emergency treatment and hospitalization events due to heart failure ( OR=2.91, 95 %CI: 1.72-4.93) and 1.72-fold increase ( OR=2.72, 95 %CI: 1.56-4.74), respectively. Conclusions:PIM increases the risk of emergency treatment or hospitalization due to heart failure in elderly outpatients, but it is not an independent influencing factor. Age ≥75 years and diuretics use were independent influencing factors of emergency treatment or hospitalization in elderly patients.
