Abstract:
OBJECTIVE:To investigate the effect of improved nursing strategy on prognosis of older immunosuppressed patients with pneumonia and sepsis.
METHODS:A prospective study was conducted. The older immunosuppressed patients with pneumonia and sepsis admitted to the department of intensive care medicine and emergency intensive care unit (ICU) of Peking Union Medical College Hospital from January 2017 to July 2022 were enrolled. In the first stage (from January 2017 to December 2019), patients received the original nursing strategy (original nursing strategy group), including: (1) nurses were randomly assigned; (2) routine terminal cleaning; (3) ICU environmental cleaning twice a day; (4) oral care was performed with chlorhexidine twice a day; (5) original lung physiotherapy [head of bed elevated at 30 degree angle-45 degree angle, maintaining a Richmond agitation-sedation scale (RASS) -2 to 1, sputum aspiration as needed]. After 1 month of learning and training of the modified nursing treatment strategy for nurses and related medical staff, the patients in the second stage (from February 2020 to July 2022) received the improved nursing strategy (improved nursing strategy group). The improved nursing strategy improved the hospital infection prevention and control strategy and lung physical therapy strategy on the basis of the original nursing strategy, including: (1) nurses were fixed assigned; (2) patients were placed in a private room; (3) enhanced terminal cleaning; (4) ICU environmental cleaning four times a day; (5) education and training in hand hygiene among health care workers was improved; (6) bathing with 2% chlorhexidinegluconate was performed once daily; (7) oral care with a combination of chlorhexidine and colistin was provided every 6 hours; (8) surveillance of colonization was conducted; (9) improved lung physiotherapy (on the basis of the original lung physiotherapy, delirium score was assessed to guide early mobilization of the patients; airway drainage was enhanced, the degree of airway humidification was adjusted according to the sputum properties, achieving sputum viscosity grade II; lung ultrasound was also used for lung assessment, and patients with atelectasis were placed in high lateral position and received the lung recruitment maneuver). Baseline patient information were collected, including gender, age, underlying diseases, source of admission, disease severity scores, vital signs, ventilatory parameters, blood gas analysis, life-sustaining treatments, clinical laboratory evaluation, indicators of infection and inflammation, pathogens and drug therapy. The primary outcome was 28-day mortality, and the secondary outcomes were duration of mechanical ventilation, length of ICU stay, and ICU mortality. Multivariate Logistic regression analysis was used to determine the risk factors for 28-day death in older immunosuppressed patients with pneumonia and sepsis.
RESULTS:Finally, 550 patients were enrolled, including 199 patients in the original nursing strategy group and 351 patients in the improved nursing strategy group. No significant differences were found in gender, age, underlying diseases, source of admission, disease severity scores, vital signs, ventilatory parameters, blood gas analysis, life-sustaining treatments, clinical laboratory evaluation, indicators of infection and inflammation, coexisting pathogens or drug therapy between the two groups. Compared with patients in the original nursing strategy group, those in the improved nursing strategy group had significantly fewer duration of mechanical ventilation and length of ICU stay [duration of mechanical ventilation (days): 5 (4, 7) vs. 5 (4, 9), length of ICU stay (days): 11 (6, 17) vs. 12 (6, 23), both P < 0.01], and lower ICU mortality and 28-day mortality [ICU mortality: 23.9% (84/351) vs. 32.7% (65/199), 28-day mortality: 23.1% (81/351) vs. 33.7% (67/199), both P < 0.05]. Multivariate Logistic regression analysis showed that the improved nursing strategy acted as an independent protective factor in 28-day death of older immunosuppressed patients with pneumonia and sepsis [odds ratio (OR) = 0.543, 95% confidence interval (95%CI) was 0.334-0.885, P = 0.014].
CONCLUSIONS:Improved nursing strategy shortened the duration of mechanical ventilation and the length of ICU stay, and decreased ICU mortality and 28-day mortality in older immunosuppressed patients with pneumonia and sepsis, significantly improving the short-term prognosis of such patients.
