Cai D, Wang Y, Chen X. Relationship between nutrition indicators and pneumonia risk among stable schizophrenia patients: a retrospective study. Psychogeriatrics 2024; 24:861-867. [PMID: 38769596 DOI: 10.1111/psyg.13133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Accepted: 05/11/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND It is reported that reduced physical activity and malnutrition may trigger pneumonia, and the utilisation of the geriatric nutritional risk index (GNRI) upon admission to long-term nursing care can enable the implementation of accurate and timely rehabilitation and nutritional support, which may, in turn, minimise pneumonia incidence. However, to date, there is no reported association between GNRI and pneumonia among stable schizophrenic patients. METHODS This is a retrospective investigation. We enrolled 434 hospitalised subjects aged ≥50 years, who were diagnosed with stable schizophrenia between January 2017 and June 2022. Baseline nutritional status information during the stable stage of schizophrenia was evaluated using body mass index, serum albumin, and GNRI. In addition, pneumonia-based information, including diagnosis and treatment, was retrospectively obtained within 1 year. To examine the potential association between nutrition indicators and pneumonia risk among stable schizophrenia patients, we employed a logistic regression analysis. RESULTS The pneumonia incidence among all stable schizophrenia patients was 10.14%, and there were no statistically significant difference between sexes (male vs. female, 10.63% vs. 9.44%, P = 0.687). Based on the univariate analysis of nutrition indicators and pneumonia, female patients exhibited a strong correlation between serum albumin and pneumonia (P = 0.022). Furthermore, we adjusted for potential influencing factors of pneumonia infection, and confirmed that only serum albumin was linked to pneumonia risk in female stable schizophrenia patients (odds ratio = 0.854, 95% CI: 0.749-0.975, P = 0.02). CONCLUSIONS Based on our analysis, serum albumin was strongly correlated with pneumonia risk in female stable schizophrenia patients.

Abstract
Introduction The incidence of hospital-acquired pneumonia (HAP) is high in the medical setting for mental disorders. To date, effective measurements for preventing HAP in hospitalized mental disorder patients are unavailable. Methods This study was conducted at the Large-Scale Mental Health Center of Renmin Hospital of Wuhan University (Wuhan, China) in two phases: baseline phase (January 2017-December 2019) and intervention phase (May 2020-April 2022). In the intervention phase, the HAP bundle management strategy was implemented in the Mental Health Center, and the data on HAP were collected continuously for analysis. Results A total of 18,795 and 9,618 patients were included in the baseline and intervention phases, respectively. The age, gender, ward admitted to, type of mental disorder, and Charlson comorbidity index did not differ significantly. After intervention, the rate of HAP occurrence decreased from 0.95 to 0.52% (P < 0.001). Specifically, the HAP rate decreased from 1.70 to 0.95% (P = 0.007) in the closed ward and from 0.63 to 0.35% (P = 0.009) in the open ward. The HAP rate in the subgroups was higher in patients with schizophrenia spectrum disorders (1.66 vs. 0.74%) and organic mental disorders (4.92 vs. 1.41%), and in those ≥65 years old (2.82 vs. 1.11%) but decreased significantly after intervention (all P < 0.05). Conclusion The implementation of the HAP bundle management strategy reduced the occurrence of HAP in hospitalized patients with mental disorders.

Abstract
PURPOSE Antipsychotics, particularly long-acting injectable (LAI) agents, are associated with decreased all-cause mortality. Antipsychotics are also associated with an increased prevalence of infections. We performed a systematic review and meta-analysis of the risk of infections in patients with schizophrenia treated with LAIs versus placebo. METHODS We systematically searched PubMed and Food and Drug Administration package inserts for placebo-controlled studies of LAI antipsychotic use in schizophrenia. Random effects meta-analysis calculating odds ratios and 95% confidence intervals for any and site-specific infections were performed. RESULTS The total study sample consisted of 2559 subjects with schizophrenia, with 867 receiving placebo and 1692 LAI antipsychotics. Long-acting injectable antipsychotic use was associated with a significant 1.75-fold increased odds of any infection versus placebo (2.4% vs 1.5%; odds ratio, 1.75; 95% confidence interval, 1.16-2.66; P = 0.008), although findings for specific infections did not reach statistical significance. The association between LAIs and infection was unrelated to study duration, age, sex, body mass index, and total psychopathology. CONCLUSIONS Our findings suggest that LAIs are associated with a small, but significant, increased risk of infections. This association may be due to immunomodulatory effects of antipsychotics.

Sex differences in factors influencing hospital-acquired pneumonia in schizophrenia patients receiving modified electroconvulsive therapy. Front Psychiatry 2023; 14:1127262. [PMID: 36865072 PMCID: PMC9971594 DOI: 10.3389/fpsyt.2023.1127262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 01/30/2023] [Indexed: 02/16/2023] Open
Abstract
BACKGROUND Sex differences may be presented in the clinical features or symptoms of schizophrenia patients but also affect the occurrence of hospital-acquired pneumonia (HAP). Modified electroconvulsive therapy (mECT) is a common treatment method for schizophrenia, used in combination with antipsychotics. This retrospective research explores the sex difference in HAP affecting patients with schizophrenia who have received mECT treatment during hospitalization. METHODS We included schizophrenia inpatients treated with mECT and antipsychotics between January 2015 and April 2022. Blood-related and demographic data collected on admission were analyzed. Influencing factors of HAP in male and female groups were assessed separately. RESULTS A total of 951 schizophrenia patients treated with mECT were enrolled in the study, including 375 males and 576 females, of which 62 patients experienced HAP during hospitalization. The risk period of HAP in these patients was found to be the first day after each mECT treatment and the first three sessions of mECT treatment. Statistically significant differences in the incidence of HAP were identified in male vs. female groups, with an incidence in men about 2.3 times higher than that in women (P < 0.001). Lower total cholesterol (Z = -2.147, P = 0.032) and the use of anti-parkinsonian drugs (χ2 = 17.973, P < 0.001) were found to be independent risk factors of HAP in male patients, while lower lymphocyte count (Z = -2.408, P = 0.016), hypertension (χ2 = 9.096, P = 0.003), and use of sedative-hypnotic drugs (χ2 = 13.636, P < 0.001) were identified in female patients. CONCLUSION Influencing factors of HAP in schizophrenia patients treated with mECT have gender differences. The first day after each mECT treatment and the first three sessions of mECT treatment were identified to have the greatest risk for HAP development. Therefore, it would be imperative to monitor clinical management and medications during this period according to these gender differences.

Abstract
BACKGROUND Few researchers have investigated the incidence of and risk factors for hospital-acquired pneumonia (HAP) among inpatients with mental disorders in a general hospital. METHODS This study included patients with mental disorders hospitalized in a large mental health center (situated in a general hospital) between January 1, 2017 and July 31, 2021 (excluding January 1, 2020 to May 31, 2020). Risk factors for HAP were identified by logistic regression analysis after propensity score matching (PSM, 1:4) for gender, age, duration of observation and hospital ward. RESULTS The study included 16,864 patients. HAP incidence rate was 1.15% overall, 2.11% on closed wards, 0.75% on open wards, 4.45% in patients with organic mental disorders, 1.80% in patients with schizophrenia spectrum disorder, and 0.84% in patients with mood disorders. Risk factors for HAP after PSM were hypoproteinemia, chronic liver disease, use of clozapine, hospitalization during the previous 180 days, body mass index (BMI) ≤18.5 kg/m2, cholinesterase inhibitor use and mood stabilizer use. CONCLUSION HAP was common among inpatients with mental disorders. Risk factors for HAP in patients with mental disorders include hypoproteinemia, chronic liver disease, hospitalization during the past 180 days, BMI ≤18.5 kg/m2, and use of clozapine, cholinesterase inhibitors or mood stabilizers.

Non-antipsychotic medicines and modified electroconvulsive therapy are risk factors for hospital-acquired pneumonia in schizophrenia patients. Front Psychiatry 2022; 13:1071079. [PMID: 36713903 PMCID: PMC9880231 DOI: 10.3389/fpsyt.2022.1071079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 12/28/2022] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Hospital-acquired pneumonia (HAP) has a significant and detrimental impact on schizophrenia patients. Non-antipsychotic medicines and modified electroconvulsive therapy (MECT) are frequently used in conjunction with antipsychotics to treat schizophrenia. Whether non-antipsychotic medicines or MECT are risk factors for HAP in schizophrenia treated with antipsychotics is still unknown. METHODS Patients with schizophrenia who were admitted to the Fourth People's Hospital of Chengdu between January 2015 and April 2022 were included in this retrospective cohort study. Individuals with HAP were 1:1 matched to individuals without HAP (non-HAP) using propensity score matching (PSM). The risk factors for HAP were analyzed by comparing the two groups. RESULTS A total of 7,085 schizophrenia patients were included in this study, with a mean age of 39.77 ± 14.45 years. 193 patients developed HAP on an average of 22.26 ± 21.68 days after admission with an incidence of 2.73%. After 1:1 PSM, 192 patients from each group (HAP and non-HAP) were included. The HAP group had significantly more patients with MECT and taking benzodiazepines, antidepressants, mood stabilizers, and anti-parkinsonians both before and after PSM by Bonferroni correction (P < 0.001). Multivariate logistic regression analysis showed that, combined with antipsychotics, non-antipsychotic medicines including benzodiazepines (OR = 3.13, 95%CI = 1.95-5.03, P < 0.001), mood stabilizers (OR =3.33, 95%CI =1.79-6.20, P < 0.001) and MECT (OR =2.58, 95%CI =1.49-4.46, P = 0.001) were associated with a significantly increased incidence of HAP. CONCLUSION The incidence of HAP in schizophrenia patients in our cohort was 2.73%. MECT and non-antipsychotic medicines, including benzodiazepines and mood stabilizers were risk factors for HAP in schizophrenia patients treated with antipsychotics.

Abstract
AIM We investigated the relationship between the sarcopenia-indicating Ishii test scores and pneumonia risk in stable schizophrenia patients. METHODS This prospective investigation involves schizophrenic inpatients from two mental health centers in western China. Patient baseline information was gathered over 1 month from September 1 to 30 in 2020. All pneumonia-related patient information, including diagnosis and treatment, was acquired over 1 year between October 2020 and October 2021. Patients with schizophrenia were screened for sarcopenia utilizing a threshold value established by Ishii et al. Using regression analysis, the link between Ishii test scores and pneumonia risk in schizophrenia patients was investigated. RESULT This study recruited 232 males and 107 females with schizophrenia over the age of 50 and older. During a 1-year follow-up period, four patients (3 males and 1 female) acquired pneumonia within 1 week of relapse in schizophrenia; therefore, these patients were excluded from the study. Finally, data were collected for 335 patients. The pneumonia incidences were 29.3% in males and 14.2% in females. Our analysis confirmed that compared to the male schizophrenia patients with Ishii test scores < 105 (non-sarcopenia), those with Ishii test scores ≥ 105 (sarcopenia) exhibited an elevated pneumonia risk (OR = 2.739, 95%CI: 1.406-5.333). Following confounders adjustment, Ishii test scores ≥ 105 remained a risk factor for pneumonia (OR = 2.064, 95%CI: 1.029-4.143). Among females with schizophrenia, the Ishii test scores were not associated with pneumonia risk. CONCLUSION In conclusion, our results demonstrated that the Ishii test scores ≥ 105 were strongly associated with pneumonia risk in stable schizophrenic male patients.
