The objective of this study is to describe the prevalence of benzodiazepine in a sample of patients (≥65 years) attended by liaison psychiatry units (LPU) in Spain and its possible relation to falls.

This is an observational., cross-sectional, multicenter study. We obtained data from a sample of 165 patients (≥65 years) admitted to 7 general hospitals in Spain referred from different departments to each liaison psychiatry unit. Data was collected for a month and a half period. Psychiatric evaluations were performed while the patients were on wards.

We obtained a sample of 165 patients (78 women, 88 men) with a mean age of 76,03 years old (42.10% <75 years, 57,83% ≥ 75 years). Most of them were married and they lived accompanied (67,27%). Only 5,45% lived in a nursing home. 65,45% of patients had prescribed at least one psychotropic drug before LPU intervention; mainly (50,9%) benzodiazepines (60%women/40%men). 70,9% of these group of patients had more than one psychotropic drug prescribed before LPU. After LPU intervention in 39,39% at least one drug was withdrawn (in 50,81 % of cases benzodiazepines). Falls in the past 6 months were reported in 24.8% of total patients. Patients under benzodiazepine treatment had fallen in 29% of cases. After LPU intervention benzodiazepines were withdrawn in 56,25% % of them.

Benzodiazepines are widely used in our sample and frequently is associated with polypharmacy. LPU intervention might be a useful tool to reduce the use of them, specially for those who reported falls.

Longitudinal studies might be carried out to study these factors and their possible relationship with falls, given that Benzodiazepines are consistently associated with a higher risk of falls. It is unclear whether specific subgroups such as short-acting benzodiazepines and selective serotonin reuptake inhibitors are safer in terms of fall risk. Ppropriate prescription of medications such as BZDs is an important public health issue.

The objective of this study is to describe the diagnostic agreement between physicians and liaison psychiatry units (LPU) in 7 general hospitals of Spain for elderly patients and to analyze possible factors related to it.

This is an observational., cross-sectional, multicenter study. We obtained data from a sample of 165 patients (≥65 years) admitted to 7 general hospitals in Spain referred from different departments to each liaison psychiatry unit. Data was collected for a month and a half period. Psychiatric evaluations were performed while the patients were on wards.

We obtained a sample of 165 patients (78 women, 88 men) with a mean age of 76,03 years old (42.10% <75 years, 57,83% ≥ 75 years). Most of them were married and they lived accompanied (67,27%). Only 5,45% lived in a nursing home.

In 55.15% the main reason to referral was anxiety/depression symptoms. 42,42% had no psychiatry medical background. After LPU visit a new diagnosis was done in 56.96%. Main diagnoses were adjustments disorders (26,66%), delirium (20,6%) and no psychiatric pathology (14,54%)

Cohen’s kappa statistics were used to estimate the agreement between the diagnoses made by LPU and the diagnoses considered by the referring doctors. We obtained a moderate global agreement (kappa= 0,4971) between observers (0,424 for <75 years, 0,557 for ≥65 years) Moderate agreement was found for alcohol or substance abuse (kappa= 0,41) and low agreement was found for affective disorders (kappa= 0,3278) and delirium/ psychological and behavioral symptoms in dementia (Kappa= 0,2341).

We analyzed factors which might affect de agreement between physicians and LPU such is group of age, functional impairment, comorbidity by Charlson index and previous diagnosis of dementia.

Further longitudinal studies might help in the future to analyze the factors related to agreement between doctors and might help to establish educational programs

It is well known that geriatric patients are at increased risk of developing comorbid medical and psychiatric conditions, and a large proportion of them are admitted to psychiatric liaison units (LPUs). The aim of this study is to determine which clinical differences between age groups (65- 74 years and ≥75 years) are statistically significant to potentially warrant special attention when referring to an LPU.

This is an observational, cross-sectional and comparative multicentre study. We collected data from 165 patients (≥65 years) admitted to 7 Spanish general hospitals and referred to each LPU from different departments. Data were collected over a period of one and a half months. Psychiatric examinations were performed during the patients' stay in the wards. The sample was divided into two age groups of patients and a comparative analysis was done.

We obtained a sample of 165 patients with a mean age of 76.03 years (42.10% < 75 years, 57.83% ≥ 75 years). We analysed several variables between two age groups: the youngest (65- 74 years) and the oldest (≥75 years). In the younger group (mean age 69.87 years), the mean Barthel index before admission was 93.23 (52.1% with independent ambulation) and at the time of our first assessment was 54.62, before 82.71 of the older group (mean age 80.63). The mean Lawton index was 4.44 (6.35 for the older group) and the Charlson index was 6.38 (5.6 for the older group). 21.11% reported falls in the last 6 months, compared to 27.6% in the older group. The most common reason for referral was anxiety/depression symptoms in both groups (52.12% and 56.53%) and agitation (24.46% in the older group). After the LPU visit, the main diagnoses were adjustment disorder in both groups (25.3% and 25.53%) and delirium in the older group (23.4%). Antidepressants and benzodiazepines were the most common psychotropic drugs prescribed before the LPU visit, and benzodiazepines were the most common drugs discontinued after the LPU visit in both groups.

Clinical differences were found between two age groups (65-74 years and ≥75 years) at LPU, which could allow professionals to improve their attention and interventions.

Delirium is an acute and fluctuating disorder characterized by a disturbance in attention and cognition that is commonly observed in hospitalized older adults; being present in up to 23% of patients admitted to a general medical service and as many as 85% of patients in the intensive care unit. Delirium causes complications such as increased morbidity, persistent functional decline, mortality, increased frailty and increased length of hospital stay. Nonetheless, it is often underdiagnosed, especially when it occurs in its hypoactive form. The objective of this study is to describe characteristics and factors associated with the presence of delirium in patients ≥65 years treated by the liaison psychiatric units in seven general hospitals.

This is an observational, cross-sectional, multicentre study. We obtained data from a sample of 165 patients (≥65 years) admitted to seven general hospitals in Spain referred from different departments to each liaison psychiatry unit. Data was collected for a month and a half period. Psychiatric evaluations were performed while the patients were on wards.

We obtained a sample of 165 patients (78 women, 88 men) with a mean age of 76,03 years old (42.10% <75 years, 57,83% ≥ 75 years). Most of them were married and they lived accompanied (67,27%). Delirium was diagnosed in 20% of the consultations. A multivariate analysis was developed with the presence of delirium as the independent variable. The nature of the underlying pathology, the presence of a previous mental disorder, functionality using the Barthel and Lawton Brody Indexes and the prescribed pharmacological treatments were used as dependent variables. Cohen’s kappa statistics were used to estimate the agreement between delirium diagnose made by psychiatrists and the diagnoses considered by the referring doctors. Low agreement was found for the presence of delirium (Kappa= 0,2341). We also explored the relationship between the presence of delirium and the mean length of stay, as well as the discharge destination of these patients.

There are still many difficulties in the diagnosis and treatment of patients with delirium. Better knowledge of the factors associated with its appearance would improve the management of these patients.

Older patients (≥65yo) admitted to general hospitals have increased in the past years. This resulted in an increase in hospitalization periods, health costs, and morbi-mortality rates in this group of patients.

Previous evidence points that the reduced time to referral (TTR) to Consultation-Liaison Psychiatry Units (CLP) leads to a reduced length of stay (LOS) in GH improving long-term prognosis of medical conditions.

This study aims to explore whether a prior disability in older patients leads to delay the search for psychiatric help. And to explore whether early referral to CLP is associated with reduced LOS in general hospitals.

This is an observational, cross-sectional, multicentre study. We obtained a complete data set from a sample of 152 patients (≥65 years old) admitted to 7 general hospitals in Spain referred to CLP unit for 1,5 months.

Mean age of the sample was 76.3 (±6.4). TTR was 14.5 (±18.0) days. LOS was 26.7 (±22.4) days, and length of stay after consultation was 12.3 (±10.3) days. Barthel Index before admission was 87.3 (±18.0) and Lawton&Brody Index before admission was 5.3 (2.7). We found a significant positive association of Barthel Index (r=0.17, p=0.042) and Lawton&Brody Index (r=0.20, p=0.014) before admission with TTR, which indicates that patients with a worse clinical status were attended earlier. Similarly, antecedents of both falling episodes (r=-0.2, p= 0.013) and walking difficulties (r=-0.24, p= 0.003) were associated with shorter TTR. TTR in Medical Departments was 11.7 (±15.0) days and in Surgical Departments was 24.0 (±22.8) days (t=-3.5, p= 0.001). TTR showed a highly significant positive correlation with LOS (r=0.89, p<0.0001) and a more discrete positive correlation with length of stay after consultation (r=0.20, p=0.016).

We confirm that a shorter TTR to CLP was related to a shorter LOS. Also, patients in medical wards had shorter TTR. In contrast to our hypothesis, we found that a higher disability prior to hospitalization led to earlier referral to CLP, meaning that these patients were assessed and treated earlier leading to better long- term prognosis and lower health costs.

Ageism is defined by the World Health Organization as stereotypes, prejudice, and discrimination towards others or oneself based on age. Ageism is thought to pose a risk to the physical and mental health of older adults, but little is known about how to measure it in LPUs. We propose that a form of ageism can be detected by comparing the referrals made by liaison psychiatry services among patients over age 65 at discharge with functional status and medical comorbidity. Our hypothesis is that the worse the functional index and medical comorbidity, the fewer referrals to psychiatric services and the more referrals to primary care physicians.

This is an observational, cross-sectional, multicenter study. We obtained data from a sample of 165 patients (≥65 years) admitted to seven general hospitals in Spain referred from different departments to each LPU. Data was collected over a period of one and a half months. Psychiatric evaluations were performed while the patients were in the wards. Sociodemographic, clinical, and care variables were collected. Functional status was measured with the Barthel and Lawton index and comorbidity with the Charlson index.

We obtained a sample of 165 patients with a mean age of 76,03 years old. The mean Barthel index was 87,18 previous admission and 61,15 at the time of our first visit. The mean Lawton index was 5,266667 and the Charlson index was 6,03. The different options for referral were primary care physician, psychiatric facilities, nursing homes, substance use centers, or exitus. Statistical analysis was performed using the nonparametric Kruskal-Wallis test to determine if there were significant differences (p < 0,05) between the indices and referrals. Contrary to our hypothesis, statistical significance was observed only for the Lawton index, but with more referrals to psychiatric facilities among patients with the worst functional scores. No other statistical significance was observed.

Functional status and medical comorbidity did not play a role in the referral of inpatients managed by LPUs. Further studies are needed to clarify whether there is any form of ageism in the referral of elderly inpatients attended by Psychiatric Liaison Units.

To identify urinary catheter (UC)–associated urinary tract infection (CAUTI) incidence and risk factors.

A prospective cohort study.

The study was conducted across 623 ICUs of 224 hospitals in 114 cities in 37 African, Asian, Eastern European, Latin American, and Middle Eastern countries.

The study included 169,036 patients, hospitalized for 1,166,593 patient days.

Data collection took place from January 1, 2014, to February 12, 2022. We identified CAUTI rates per 1,000 UC days and UC device utilization (DU) ratios stratified by country, by ICU type, by facility ownership type, by World Bank country classification by income level, and by UC type. To estimate CAUTI risk factors, we analyzed 11 variables using multiple logistic regression.

Participant patients acquired 2,010 CAUTIs. The pooled CAUTI rate was 2.83 per 1,000 UC days. The highest CAUTI rate was associated with the use of suprapubic catheters (3.93 CAUTIs per 1,000 UC days); with patients hospitalized in Eastern Europe (14.03) and in Asia (6.28); with patients hospitalized in trauma (7.97), neurologic (6.28), and neurosurgical ICUs (4.95); with patients hospitalized in lower–middle-income countries (3.05); and with patients in public hospitals (5.89).

The following variables were independently associated with CAUTI: Age (adjusted odds ratio [aOR], 1.01; P < .0001), female sex (aOR, 1.39; P < .0001), length of stay (LOS) before CAUTI-acquisition (aOR, 1.05; P < .0001), UC DU ratio (aOR, 1.09; P < .0001), public facilities (aOR, 2.24; P < .0001), and neurologic ICUs (aOR, 11.49; P < .0001).

CAUTI rates are higher in patients with suprapubic catheters, in middle-income countries, in public hospitals, in trauma and neurologic ICUs, and in Eastern European and Asian facilities.

Based on findings regarding risk factors for CAUTI, focus on reducing LOS and UC utilization is warranted, as well as implementing evidence-based CAUTI-prevention recommendations.

To identify central-line (CL)–associated bloodstream infection (CLABSI) incidence and risk factors in low- and middle-income countries (LMICs).

From July 1, 1998, to February 12, 2022, we conducted a multinational multicenter prospective cohort study using online standardized surveillance system and unified forms.

The study included 728 ICUs of 286 hospitals in 147 cities in 41 African, Asian, Eastern European, Latin American, and Middle Eastern countries.

In total, 278,241 patients followed during 1,815,043 patient days acquired 3,537 CLABSIs.

For the CLABSI rate, we used CL days as the denominator and the number of CLABSIs as the numerator. Using multiple logistic regression, outcomes are shown as adjusted odds ratios (aORs).

The pooled CLABSI rate was 4.82 CLABSIs per 1,000 CL days, which is significantly higher than that reported by the Centers for Disease Control and Prevention National Healthcare Safety Network (CDC NHSN). We analyzed 11 variables, and the following variables were independently and significantly associated with CLABSI: length of stay (LOS), risk increasing 3% daily (aOR, 1.03; 95% CI, 1.03–1.04; P < .0001), number of CL days, risk increasing 4% per CL day (aOR, 1.04; 95% CI, 1.03–1.04; P < .0001), surgical hospitalization (aOR, 1.12; 95% CI, 1.03–1.21; P < .0001), tracheostomy use (aOR, 1.52; 95% CI, 1.23–1.88; P < .0001), hospitalization at a publicly owned facility (aOR, 3.04; 95% CI, 2.31–4.01; P <.0001) or at a teaching hospital (aOR, 2.91; 95% CI, 2.22–3.83; P < .0001), hospitalization in a middle-income country (aOR, 2.41; 95% CI, 2.09–2.77; P < .0001). The ICU type with highest risk was adult oncology (aOR, 4.35; 95% CI, 3.11–6.09; P < .0001), followed by pediatric oncology (aOR, 2.51;95% CI, 1.57–3.99; P < .0001), and pediatric (aOR, 2.34; 95% CI, 1.81–3.01; P < .0001). The CL type with the highest risk was internal-jugular (aOR, 3.01; 95% CI, 2.71–3.33; P < .0001), followed by femoral (aOR, 2.29; 95% CI, 1.96–2.68; P < .0001). Peripherally inserted central catheter (PICC) was the CL with the lowest CLABSI risk (aOR, 1.48; 95% CI, 1.02–2.18; P = .04).

The following CLABSI risk factors are unlikely to change: country income level, facility ownership, hospitalization type, and ICU type. These findings suggest a focus on reducing LOS, CL days, and tracheostomy; using PICC instead of internal-jugular or femoral CL; and implementing evidence-based CLABSI prevention recommendations.

Rates of ventilator-associated pneumonia (VAP) in low- and middle-income countries (LMIC) are several times above those of high-income countries. The objective of this study was to identify risk factors (RFs) for VAP cases in ICUs of LMICs.

Prospective cohort study.

This study was conducted across 743 ICUs of 282 hospitals in 144 cities in 42 Asian, African, European, Latin American, and Middle Eastern countries.

The study included patients admitted to ICUs across 24 years.

In total, 289,643 patients were followed during 1,951,405 patient days and acquired 8,236 VAPs. We analyzed 10 independent variables. Multiple logistic regression identified the following independent VAP RFs: male sex (adjusted odds ratio [aOR], 1.22; 95% confidence interval [CI], 1.16–1.28; P < .0001); longer length of stay (LOS), which increased the risk 7% per day (aOR, 1.07; 95% CI, 1.07–1.08; P < .0001); mechanical ventilation (MV) utilization ratio (aOR, 1.27; 95% CI, 1.23–1.31; P < .0001); continuous positive airway pressure (CPAP), which was associated with the highest risk (aOR, 13.38; 95% CI, 11.57–15.48; P < .0001); tracheostomy connected to a MV, which was associated with the next-highest risk (aOR, 8.31; 95% CI, 7.21–9.58; P < .0001); endotracheal tube connected to a MV (aOR, 6.76; 95% CI, 6.34–7.21; P < .0001); surgical hospitalization (aOR, 1.23; 95% CI, 1.17–1.29; P < .0001); admission to a public hospital (aOR, 1.59; 95% CI, 1.35-1.86; P < .0001); middle-income country (aOR, 1.22; 95% CI, 15–1.29; P < .0001); admission to an adult-oncology ICU, which was associated with the highest risk (aOR, 4.05; 95% CI, 3.22–5.09; P < .0001), admission to a neurologic ICU, which was associated with the next-highest risk (aOR, 2.48; 95% CI, 1.78–3.45; P < .0001); and admission to a respiratory ICU (aOR, 2.35; 95% CI, 1.79–3.07; P < .0001). Admission to a coronary ICU showed the lowest risk (aOR, 0.63; 95% CI, 0.51–0.77; P < .0001).

Some identified VAP RFs are unlikely to change: sex, hospitalization type, ICU type, facility ownership, and country income level. Based on our results, we recommend focusing on strategies to reduce LOS, to reduce the MV utilization ratio, to limit CPAP use and implementing a set of evidence-based VAP prevention recommendations.

Technology-based interventions (TBIs) are a useful approach when attempting to provide therapy to more patients with psychosis.

Randomized controlled trials of outcomes of TBIs v. face-to-face interventions in psychosis were identified in a systematic search conducted in PubMed/Ovid MEDLINE. Data were extracted independently by two researchers, and standardized mean changes were pooled using a three-level model and network meta-analysis.

Fifty-eight studies were included. TBIs complementing treatment as usual (TAU) were generally superior to face-to-face interventions (g = 0.16, p ≤ 0.0001) and to specific outcomes, namely, neurocognition (g = 0.13, p ≤ 0.0001), functioning (g = 0.25, p = 0.006), and social cognition (g = 0.32, p ≤ 0.05). Based on the network meta-analysis, the effect of two TBIs differed significantly from zero; these were the TBIs cognitive training for the neurocognitive outcome [g = 0.16; 95% confidence interval (CI) 0.09–0.23] and cognitive behavioral therapy for quality of life (g = 1.27; 95% CI 0.46–2.08). The variables educational level, type of medication, frequency of the intervention, and contact during the intervention moderated the effectiveness of TBIs over face-to-face interventions in neurocognition and symptomatology.

TBIs are effective for the management of neurocognition, symptomatology, functioning, social cognition, and quality of life outcomes in patients with psychosis. The results of the network meta-analysis showed the efficacy of some TBIs for neurocognition, symptomatology, and quality of life. Therefore, TBIs should be considered a complement to TAU in patients with psychosis.
