A latent class analysis of prolonged mechanical ventilation patients at a long-term acute care hospital: Subtype differences in clinical outcomes

Rapid Response Systems at a Long-Term Acute Care Hospital

Rapid Response Systems (RRS) improve patient outcomes at large medical centers. Little is known about how RRS are used in other medical settings. The purpose of this exploratory study was to describe RRS events at a long-term acute care hospital (LTACH). We conducted a retrospective review of 71 RRS event records at an urban 50-bed Midwestern LTACH. Measures included demographic data, triggering mechanisms, contextual factors, mechanism factors, and clinical outcomes. Of patients who experienced a RRS event, median age was 71 (62, 80) years; 52.1% were female; most (n = 49, 69%) were "full code." Most (n = 41, 58%) events occurred during the daytime. The most common trigger was "mental status changes/unresponsiveness." Registered nurses were the most frequent activator (n = 19, 26.8%) and responders (n = 63, 60.6%). Median duration of RRS events was 14 (6, 25) minutes. Most patients stabilized and their condition improved (n = 54, 76.1%). RRS can be expanded and modified to the LTACH population.

Characteristics and Risk Factors of Children Requiring Prolonged Mechanical Ventilation vs. Non-prolonged Mechanical Ventilation in the PICU: A Prospective Single-Center Study

BACKGROUND

Prolonged mechanical ventilation (PMV) has become an enormous challenge in intensive care units (ICUs) around the world. Patients treated with PMV are generally in poor health. These patients represent a select cohort with significant morbidity, mortality, and resource utilization. The status of children who have undergone PMV in China is unknown. Our goal is to investigate the prevalence and characteristics of pediatric patients with PMV, as well as the risk factors of PMV in the pediatric intensive care unit (PICU).

METHODS

The subjects were divided into two groups. The PMV group(MV ≥ 14 days) and the non-PMV group(2 days < MV <14 days). The baseline characteristics, treatments, mortality and other results between the two groups were compared. The risk factors associated with PMV were evaluated using univariate and multivariable analyses.

RESULTS

Of the 382 children enrolled, 127 (33.2%) received prolonged mechanical ventilation. The most common cause of MV in the PMV group was acute lung disease (48.0%), followed by acute circulatory system disease (26.0%), acute neurological disease (15.0%), postoperative monitoring (10.2%), and others (0.8%). Comorbidities were more prevalent among the PMV group (P = 0.004). The patients with PMV had a higher rate of premature birth (24.4 vs. 14.1%, P = 0.013) and higher PIM3 score at admission [5.6(3.0-9.9) vs. 4.1(1.7-5.5), P < 0.001]. The use of inotropes/vasopressors (63.8 vs. 43.1%, P < 0.001) was more common in patients with PMV compared with those in the non-PMV group. In the PMV group, the rate of extubation failure (39.4 vs. 6.7%, P < 0.001) was higher than the non-PMV group. The median hospital stay [35(23.0-50.0)d vs. 20(14.0-31.0)d, P < 0.001], PICU stay [22(15.0-33.0)d vs. 9(6.0-12.0)d, P < 0.001], hospitalization costs [¥391,925(263,259-614,471) vs. ¥239,497(158,723-350,620), P < 0.001], and mortality after 1-month discharge (22.0 vs. 1.6%, P < 0.001) were higher in the PMV group. Multivariate analysis revealed that age <1 year old, a higher PIM3 score at admission, prematurity, the use of inotropes or vasopressors, extubation failure, and ventilator mode on the first day of MV were associated with PMV.

CONCLUSIONS

The incidence and mortality of PMV in pediatric patients is surprisingly high. Premature infants or patients with severe disease or extubation failure are at higher risk of PMV. Patients with PMV exhibit a greater burden with regard to medical costs than those on non-PMV. It is important to establish specialized weaning units for mechanically ventilated patients with stable conditions.

Distinct dyadic coping profiles in Chinese couples with breast cancer

PURPOSE

Conceptualizing cancer as a dyadic stress provides new insight into how stress impacts couples with breast cancer. The present study aimed to identify subgroups with distinct dyadic coping profiles in a sample of Chinese couples with breast cancer and to determine how these subgroups differed in terms of demographic and clinical characteristics in addition to marital adjustment outcomes.

METHODS

Using convenience sampling, a cross-sectional survey was conducted. Couples with breast cancer completed the general information questionnaire, the Dyadic Coping Inventory, and the Locke-Wollance Marital Adjustment Test. The modeling was performed using a latent profile analysis to identify the dyadic coping subgroups. Parametric and nonparametric tests were applied to examine between-group differences across the identified classes.

RESULTS

The analytical results supported a three-class solution of dyadic coping groups: high (27.4%), medium (32.2%), and low (40.4%). Between-group differences were found in educational background, number of children, postoperative time, and type of surgery.

CONCLUSION

Most couples reported low levels of dyadic coping. The couples with an educational level of primary school or below, with one child or who were childless, and who had undergone breast preservation surgery within the past year were more likely to belong to the low dyadic coping group. When supporting couples with breast cancer, it is essential to assess several demographic and clinical risk factors in addition to the marital adjustment level to identify high-risk subgroups that warrant intervention.
