Determinants of Bladder Care at Night in a Subacute Ward for Aged Patients: An Observational Study.

PURPOSE: The purpose of this study was to evaluate how bladder care at night correlates to patients' mobility status. DESIGN: This was an observational study. SUBJECTS AND SETTING: The sample comprises 63 aged care subacute patients who were observed over 3 consecutive nights in an inpatient subacute aged care ward located in Melbourne, Australia. Half of the participants were female; their mean age was 82.0 (standard deviation 8.2) years. Data were collected from December 2020 to March 2021. METHODS: Outcome variables included demographic and pertinent clinical characteristics, type and timing of toileting and/or bladder care provided, and mobility classification. Descriptive statistics were used to summarize the frequency of nocturnal bladder care provided each night and as a mean over the 3 nights. The relationship between the type of care units provided and other variables was explored using a 1-way analysis of variance; values ≤.05 were deemed statistically significant. RESULTS: Findings indicate that 27% (n = 17), 41% (n = 26), and 48% (n = 30) of participants required assistance to move in bed, sit up in bed, and stand from sitting, respectively. Care episodes for both incontinence and assistance with voiding were significantly associated with functional mobility in bed ( F = 5.52, P < .001; F = 2.14, P = .02) and with ambulation independence ( F = 3.52, P = .001; F = 2.04, P = .03) but not with age or ambulation distance. CONCLUSIONS: Care provided for urinary incontinence during the night was related to the need for physical support of ambulation and poor mobility in bed. Targeted input from a multidisciplinary team is warranted to facilitate change of practice at night.

Wake-up call: 4 out of 5 older hospitalised patients have nocturnal lower urinary tract symptoms.

OBJECTIVE: Nocturnal lower urinary tract symptoms (nLUTS) increase with age, frailty and comorbid systemic illness and affect many older people. The aim of this study was to describe the prevalence of nLUTS in a hospital aged-care sub-acute environment. METHODS: Prospective clinical audit based on semi-structured bedside interviews of older adult patients admitted to a tertiary hospital aged rehabilitation ward over a 7-month period. RESULTS: A total of 147 eligible patients were included in this clinical audit. The prevalence of nLUTS was 80% (76% nocturia; 54% nocturnal urgency; 32% nocturnal enuresis; 51% nocturnal incontinence). The incidence of any nLUTs was 37%. Half the sample reported daytime incontinence, which always co-existed with at least one nLUTS. CONCLUSION: Nocturnal lower urinary tract symptoms are a problem for four out of five older hospitalised patients. This highlights the need to screen for nLUTS early in the hospital admission and for implementation of a multidisciplinary team intervention to decrease morbidity and improve quality of life in this vulnerable population.

Presenting symptoms of COVID-19 and clinical outcomes in hospitalised older adults.

BACKGROUND: In July 2020, a COVID-19 outbreak was recognised in the geriatric wards at a subacute campus of the Royal Melbourne Hospital affecting patients and staff. Patients were also admitted to this site after diagnosis in residential care. AIMS: To describe the early symptoms and the outcomes of COVID-19 in older adults. METHODS: Patients diagnosed with COVID-19 at the facility in July or August 2020 were identified and their medical records were examined to identify symptoms present before and after their diagnosis and to determine their outcomes. RESULTS: Overall, 106 patients were identified as having COVID-19, with median age of 84.3 years (range 41-104 years); 64 were diagnosed as hospital inpatients after a median length of stay of 49 days, 31 were transferred from residential aged care facilities with a known diagnosis and 11 were diagnosed after discharge. There were 95 patients included in an analysis of symptom type and timing onset. Overall, 61 (64.2%) were asymptomatic at the time of diagnosis of COVID-19, having been diagnosed through screening initiated on site. Of these, 88.6% developed symptoms of COVID-19 within 14 days. The most common initial symptom type was respiratory, but there was wide variation in presentation, including fever, gastrointestinal and neurological symptoms, many initially not recognised as being due to COVID-19. Of 104 patients, 32 died within 30 days of diagnosis. CONCLUSIONS: COVID-19 diagnosis is challenging due to the variance in symptoms. In the context of an outbreak, asymptomatic screening can identify affected patients early in the disease course.

Temporal relationships between climate variables and hand-foot-mouth disease: a multi-province study in the Mekong Delta Region, Vietnam.

Hand-foot-mouth disease (HFMD) is an emerging infectious disease that affects thousands of children every year in Vietnam, especially in the Mekong Delta Region (MDR). This study aims to analyse both provincial and regional level effects of climate factors on HFMD in multiple provinces of this high-risk region. Generalized linear models were used to analyse the daily effects of average temperature, humidity and rainfall on HFMD incidence in each province (provincial-level effects), and random-effect meta-analysis was used to estimate the pooled effect size of these climate-HFMD associations (regional-level effects). Daily effects of the climate factors on HFMD were found at both provincial level and regional level. At provincial level, temperature and humidity had statistically significant positive associations with HFMD while rainfall had both positive and negative associations with HFMD at different lag days. At regional level, temperature and humidity were positively associated with HFMD at lag 0 days (1.7%; 95%CI 0.1%-3.3%) and at lag 3 days (0.3%; 95%CI 0.1%-0.5%), respectively. In contrast, rainfall was found to be negatively associated with HFMD at lag 5 days (- 0.3%; 95%CI - 0.4% to - 0.1%). Heterogeneities of the effects of rainfall on HFMD were found to be higher than those of temperature or humidity. This is the first study to address the climate-HFMD associations in multiple provinces of the MDR. These associations draw attention to climate-related health issues and will help in developing an environment-based early warning system for HFMD prevention and control.

The effects of socioecological factors on variation of communicable diseases: A multiple-disease study at the national scale of Vietnam.

OBJECTIVE: To examine the effects of socioecological factors on multiple communicable diseases across Vietnam. METHODS: We used the Moran's I tests to evaluate spatial clusters of diseases and applied multilevel negative binomial regression models using the Bayesian framework to analyse the association between socioecological factors and the diseases queried by oral, airborne, vector-borne, and animal transmission diseases. RESULTS AND SIGNIFICANCE: The study found that oral-transmission diseases were spatially distributed across the country; whereas, the airborne-transmission diseases were more clustered in the Northwest and vector-borne transmission diseases were more clustered in the South. Most of diseases were sensitive with climatic factors. For instance, a 1°C increase in average temperature is significantly associated with 0.4% (95CI, 0.3-0.5), 2.5% (95%CI, 1.4-3.6), 0.9% (95%CI, 0.6-1.4), 1.1% (95%CI), 5% (95%CI, 3-.7.4), 0.4% (95%CI, 0.2-0.7), and 2% (95%CI, 1.5-2.8) increase in risk of diarrhoea, shigellosis, mumps, influenza, dengue, malaria, and rabies respectively. The influences of socio-economic factors on risk of communicable diseases are varied by factors with the biggest influence of population density. The research findings reflect an important implication for the climate change adaptation strategies of health sectors. A development of weather-based early warning systems should be considered to strengthen communicable disease prevention in Vietnam.

Spatiotemporal variation of hand-foot-mouth disease in relation to socioecological factors: A multiple-province analysis in Vietnam.

BACKGROUND: Hand-foot-and-mouth disease (HFMD) is a significant public health issue in Asia-pacific countries. Numerous studies have examined the relationship between socio-ecological factors and HFMD however the research findings were inconsistent. This study examined the association between socio-ecologic factors and HFMD in multiple provinces across Vietnam. METHODS: We applied a spatial autoregressive model using a Bayesian framework to examine the relationship between HFMD and socio-demographic factors. We used a Generalized Linear Model (GLD) with Poisson family to examine the province-specific association between monthly HFMD and climatic factors while controlling for spatial lag, seasonality and long-term trend of HFMD. Then, we used a random-effect meta-analysis to generate pooled effect size of climate-HFMD association for regional and country scale. RESULTS: One percent increase in newborn breastfed within 1h of birth, households with permanent houses, and households accessed to safe water resulted in 1.57% (95% CI: -2.25, -0.93), 0.96% (-1.66, -0.23), and 1.13% (-2.16, -0.18) reduction in HFMD incidence, respectively. At the country-level, HFMD increased 7% (RR: 1.07; 95%CI: 1.052-1.088) and 3.1% (RR: 1.031, 95%CI: 1.024-1.039) for 1°C increase in monthly temperature above 26°C and 1% increase in monthly humidity above 76%. Whereas, HFMD decreased 3.1% associated with 1mm increase in monthly cumulative rainfalls. The climate-HFMD relationship was varied by regions and provinces across the country. CONCLUSIONS: The findings reflect an important implication for the climate change adaptation strategies and public-health decision, of which development of weather-based early warning systems should be considered to strengthen communicable disease prevention system.

Temporal and spatial analysis of hand, foot, and mouth disease in relation to climate factors: A study in the Mekong Delta region, Vietnam.

This study examined the temporal and spatial patterns of hand, foot, and mouth disease (HFMD) in the Mekong Delta region in Vietnam. A time-series analysis was used to examine the temporal patterns of HFMD in relation to climate factors while a retrospective space-time scan was used to detect the high-risk space-time clusters of this disease. A 1°C increase in average temperature was associated with 5.6% increase in HFMD rate at lag 5days (95% CI 0.3-10.9). A 1% increase in humidity had equal influence of 1.7% increases on HFMD rate at both lag 3days and 6days (95% CI 0.7-2.7 and 95% CI 0.8-2.6, respectively). An increase in 1 unit of rainfall was associated with a 0.5% increase of HFMD rate on the lag 1 and 6days (95% CI 0.2-0.9 and 95% CI 0.1-0.8, respectively). The predictive model indicated that the peak of HFMD was from October to December - the rainy season in the Mekong Delta region. Most high-risk clusters were located in areas with high population density and close to transport routes. The findings suggest that HFMD is influenced by climate factors and is likely to increase in the future due to climate change related weather events.
