Incidence and Predictors of Nonventilator Hospital-Acquired Pneumonia in a Community Hospital

Risk factors on healthcare-associated infections among tuberculosis hospitalized patients in China from 2001 to 2020: a systematic review and meta-analysis

Background

China has been still suffering from high burden attributable to tuberculosis (TB) and healthcare-associated infections (HAIs). TB patients are at high risk to get HAIs. Evidence-based guidelines or regulations to constrain the rising HAIs among TB hospitalized patients are needed in China. The aim of this systematic review and meta-analysis is to investigate the risk factors associated with HAIs among TB hospitalized patients in Chinese hospitals.

Methods

Medline, EMBASE and Chinese Journals Online databases were searched. The search was limited to studies published from January 1st 2001 to December 31st 2020. Meta-analyses of ORs of the risk factors between patients with HAIs and patients without HAIs among TB hospitalized patients were estimated. Heterogeneity among studies was assessed based on the \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{{\uptau }}$$\end{document}τ^² and I² statistics to select the meta-analysis model. Review Manager 5.3 was employed and P < 0.05 was considered as statistical significance.

Results

851 records were filtered from the databases, of which 11 studies were included in the quantitative meta-analysis. A total of 11,922 TB patients were included in the systematic review and meta-analysis, of which 1133 were diagnosed as having HAIs. Age older than 60 years (OR: 2.89 [2.01–4.15]), complications (OR: 3.28 [2.10–5.13]), diabetes mellitus (OR: 1.63 [1.22–2.19]), invasive procedure (OR: 3.80 [2.25–6.42]), longer than 15 hospitalization days (OR: 2.09 [1.64–2.64]), secondary tuberculosis (OR: 2.25 [1.48–3.42]), smoking (OR: 1.40[1.02–1.93]), underlying disease (OR: 2.66 [1.53–4.62]), and use of antibiotics (OR: 2.77 [2.35–3.27]) were the main risk factors associated with HAIs among TB hospitalized patients with a statistical significance (P < 0.05).

Conclusions

Age older than 60 years, presence of complications, presence of diabetes mellitus, invasive procedure, longer than 15 hospitalization days, secondary tuberculosis, smoking, presence of underlying disease, and use of antibiotics were the main risk factors which had a negative impact on HAIs among TB hospitalized patients in Chinese hospitals. These findings provided evidence for policy makers and hospital managers to make effective infection prevention and control measures to constrain the rising HAIs. It is also required that more cost-effective infection prevention and control measures should be widely applied in routinely medical treatment and clinical management to reduce the occurrence of HAIs among TB hospitalized patients.

Factors predicting non-ventilated hospital-acquired pneumonia: systematic review and meta-analysis

BACKGROUND

Hospital-acquired pneumonia (HAP) results in approximately 15-20% of all infections in hospitals, with more than two-thirds being in patients not using mechanical ventilation. The incidence of non-ventilated hospital-acquired pneumonia (NVHAP) is increasing, and it is associated with a longer length of stay, the need for intensive care unit hospitalization and mechanical ventilation use, and higher mortality.

AIM

To identify, quantify, and summarize predictive factors for NVHAP in adult patients admitted to non-intensive care units as determined by previous observational studies.

METHODS

PubMed, Embase, Scopus, and LILACS were systematically searched. Case-control and cohort studies were included, and a meta-analysis was performed for all factors studied more than once. National Institute of Health assessment tools were applied to assess the quality of the studies.

FINDINGS

Thirty-eight articles showing 204 predictive factors were included. A meta-analysis was performed for 58 factors, 32 of which were significantly associated with NVHAP. When the sensitivity analysis was performed without poor-quality studies, 24 factors remained associated with NVHAP.

CONCLUSION

Although there is a lack of good-quality studies to establish predictive factors for NVHAP, the results of this study showed 24 factors associated with the development of this infectious complication. Knowledge of the significant predictive factors for NVHAP will enable the identification of patients most likely to develop it.

Evaluation of multi-component interventions for prevention of nosocomial pneumonia in older adults: a randomized, controlled trial

AIMS

To evaluate the efficacy of multi-component interventions for prevention of hospital-acquired pneumonia in older patients hospitalized in geriatric wards.

METHODS

A randomized, parallel-group, controlled trial was undertaken in patients aged 65 and above who were admitted to a tertiary hospital geriatric unit from January 1, 2016 to June 30, 2018 for an acute non-respiratory illness. Participants were randomized by to receive either a multi-component intervention (consisting of reverse Trendelenburg position, dysphagia screening, oral care and vaccinations), or usual care. The outcome measures were the proportion of patients who developed hospital-acquired pneumonia during hospitalisation, and mean time from randomization to the next hospitalisation due to respiratory infections in 1 year.

RESULTS

A total of 123 participants (median age, 85; 43.1% male) were randomized, (n = 59) to intervention group and (n = 64) to control group. The multi-component interventions did not significantly reduce the incidence of hospital-acquired pneumonia but did increase the mean time to next hospitalisation due to respiratory infection (11.5 months vs. 9.5 months; P = 0.049), and reduced the risk of hospitalisation in 1 year (18.6% vs. 34.4%; P = 0.049). Implementation of multi-component interventions increased diagnoses of oropharyngeal dysphagia (35.6% vs. 20.3%; P < 0.001) and improved the influenza (54.5% vs 17.2%; P < 0.001) and pneumococcal vaccination rates (52.5% vs. 20.3%; P < 0.001).

CONCLUSIONS

The nosocomial pneumonia multi-component intervention did not significantly reduce the incidence of hospital-acquired pneumonia during hospitalisation but reduce subsequent hospitalisations for respiratory infections.

The impact of "missed nursing care" or "care not done" on adults in health care: A rapid review for the Consensus Development Project

Aim

To identify outcomes of missed nursing care for adult patients.

Design

A five‐stage rapid review process was conducted as follows: refining the question, retrieving relevant studies, determining the studies to be included, organizing the data and synthesizing the results.

Methods

Papers published between 2010–2020 that focused on the UK, Europe, the USA and Oceania were searched for keywords in the title and abstract in major databases. The articles that identified the impact of missed nursing care on adults in health care were selected.

Results

Seventeen articles met the criteria. Major impacts of missed care in adult settings were increases in mortality, adverse events and failure to maintain. These same studies also identified a range of causative factors linked to ward environment, inadequate staffing levels and skills mix although are inconclusive. Solutions include continuing education, ward and work re‐design, and appropriate skill level.
