[PMID: 38826722 PMCID: PMC11141361 DOI: 10.1016/j.heliyon.2024.e31560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 09/10/2023] [Accepted: 05/17/2024] [Indexed: 06/04/2024] Open
Abstract
Background Elderly patients with multimorbidity are at higher risk of greater healthcare costs and poor outcomes due to decreased physical function. The aim of this study was to investigate the impact of infection on healthcare costs and poor outcomes in elderly hospitalized patients with multimorbidity. Methods We retrospectively enrolled 264 patients who met the inclusion criteria from the department of geriatrics of a large public hospital in Shanghai, China between January 2020 and December 2020. Patients were divided into two groups based on whether they had infection [infection present on admission (IPOA) or healthcare-associated infection(HAI)]. We recorded the basic information and follow-up information of all patients. The follow-up information included 30-day and 1-year all-cause readmission and mortality. Then we analyzed the association between infection and healthcare costs and clinical outcomes. Results Among 264 subjects, 47.73 % of them achieved IPOA or HAI. The 30-day poor outcomes rate was 45.45 %, and the 1-year poor outcomes rate was 78.41 %. Compared with subjects without infection, the number of drugs and the disease burden were greater in subjects with infection(P < 0.001). Subjects with infection had longer length of hospital stay(P < 0.001) and had greater healthcare cost(P < 0.001). Moreover, subjects with infection had higher poor outcomes rates of 30-day and 1-year(P < 0.001). Infection could predict greater total cost [odds ratio (OR): 1.32, 95 % CI: 1.18,1.49,P < 0.001], nursing cost(OR: 11.45, 95 % CI: 3.49,37.63,P < 0.001), and medicine cost (OR: 2.37, 95 % CI: 1.70,3.31,P < 0.001). In addition, infection was also independently associated with the 30-day poor outcomes rate(OR:3.07, 95%CI: 1.80,5.24,P < 0.001), but we found no association between infection and 1-year poor outcomes rate(OR:1.43, 95 % CI:0.73,2.79,P = 0.300) after adjustment. Conclusions Infection was a risk factor for higher healthcare cost and 30-day poor outcome rate in elderly hospitalized patients with multimorbidity.

[PMID: 35841835 DOI: 10.1016/j.micres.2022.127113] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 07/01/2022] [Accepted: 07/03/2022] [Indexed: 12/23/2022]
Abstract
Clostridioides difficile infection (CDI), which mostly occurs in hospitalized patients, is the most common and costly health care-associated disease. However, the biology of C. difficile remains incompletely understood. Current therapeutics are still challenged by the frequent recurrence of CDI. Advances in metabolomics facilitate our understanding of the etiology of CDI, which is not merely an alteration in the structure of the gut microbial community but also a dysbiosis metabolic setting promoting the germination, expansion and virulence of C. difficile. Therefore, we summarized the gut microbial and metabolic profiles for CDI under different conditions, such as those of postantibiotic treatment and postfecal microbiota transplantation. The current understanding of the role of host and gut microbial-derived metabolites as well as other nutrients in preventing or alleviating the disease symptoms of CDI will also be provided in this review. We hope that a specific nutrient-centric dietary strategy or the administration of certain nutrients to the colon could serve as an alternate line of investigation for the prophylaxis and mitigation of CDI in the future. Nevertheless, rigorously designed basic studies and randomized controlled trials need to be conducted to assess the functional mechanisms and effects of such therapeutics.

Suzuki R, Sakata N, Fushimi K. Association of body mass index with Clostridioides difficile infection among older patients with pneumonia in Japan. Geriatr Gerontol Int 2021; 22:63-67. [PMID: 34852400 DOI: 10.1111/ggi.14316] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 11/01/2021] [Accepted: 11/10/2021] [Indexed: 12/12/2022]
Abstract
AIM Obesity is reported to be a risk factor for Clostridioides difficile infection. However, obesity rarely occurs in older Asian patients, and the effects of obesity on health and disease are different in Asian and Western countries. This study aimed to assess the association between body mass index and C. difficile infection risk among older patients with pneumonia in Japan. METHODS This retrospective observational cohort study used data from the nationwide database of acute hospital inpatients' data in Japan between July 2014 and March 2016. All patients aged ≥65 years admitted with a primary diagnosis of pneumonia were enrolled. Risk factors for C. difficile infection were determined by logistic regression analysis, including known risks as covariates. RESULTS Among 221 242 pneumonia patients, 611 developed C. difficile infection. Underweight patients (body mass index <18.5 kg/m2 ) showed higher odds for C. difficile infection (odds ratio 1.38, 95% confidence interval 1.17-1.62, P < 0.001) than normal weight patients (body mass index 18.5-24.9 kg/m2 ), whereas overweight patients (body mass index ≥25 kg/m2 ) showed lower odds (odds ratio 0.63, 95% confidence interval 0.45-0.89, P < 0.01). CONCLUSIONS Body mass index was associated with C. difficile infection in older pneumonia patients in Japan. Underweight was a risk factor, whereas overweight was a protective factor for C. difficile infection. Geriatr Gerontol Int 2021; ••: ••-••.
