166463 in-hospital person-time’s records were identified in our hospital database from 2016 to 2018, and separately 54163 in 2016, 53480 in 2017, and 58820 in 2018. In three years, 950 patients underwent HACs (separately, 311 in 2016, 296 in 2017 and 343 in 2018). The overall incidence was 0.571% (separately, 0.574% in 2016, 0.553 in 2017 and 0.583 in 2018), and the two most common conditions were DVT and PE (36.79%, 351) and SSI (14.99%, 143). Interestingly, DVT and PE happened in 351 patients with the eldest mean age, while the patients with SSI had the youngest age in all in-patients in three years. It is worth noting that intraoperative devices such as the joint in an arthroplasty, vascular stent, cardiac valves, and so on were also thought as foreign objects retained after surgery according to ICD-10-CM. They weren’t considered as HACs, so there were no other conditions of foreign objects retained after surgery in our hospital. Manifestations of poor glycemic control ranked third with 5.56% (53), and followed closely by VCAIs with 5.45% (52), stage III and IV pressure ulcers with 5.14% (49), CAUTIs with 3.46% (33), and falls and trauma with 3.14% (30). Meanwhile, the proportion of iatrogenic pneumothorax with venous catheterization was less than 1% separately. Air embolism and blood incompatibility didn’t happen.
From an economic perspective, the total costs of the patients with SSI and DVT and PE ranked in 1st, and 2nd. Stage III and IV pressure ulcers and falls and trauma ranked in 1st and 2nd from the mean length of hospitalization (Table 1). Economically, stage III and IV pressure ulcers took the most averaged to every in-patient.
When comparing these conditions among three years, we saw that the occurrence rate of stage III and IV pressure ulcers, and DVT and PE became less and less. However, most of the conditions were increasing, and the total number increased in 2018 though it underwent a decrease in 2017. About the financial information of three years, no more trends can be seen, except the gradually reduced mean cost of CAUTIs. In addition, there was no rule can be found in the length of hospitalization (Figure 1, Supplementary Table 1, 2).
