Nurse Staffing Level, Length of Work Experience, and Risk of Health Care-Associated Infections Among Hospital Patients: A Prospective Record Linkage Study.

BACKGROUND: Nurse understaffing may have several adverse consequences for patients in hospitals, such as health care-associated infections (HAIs), but there is little longitudinal evidence available on staffing levels and HAIs with consideration of incubation times to confirm this. Using daily longitudinal data, we analyzed temporal associations between nurse understaffing and limited work experience, and the risk of HAIs. METHODS: The study was based on administrative data of 40 units and 261,067 inpatient periods for a hospital district in Finland in 2013-2019. Survival analyses with moving time windows were used to examine the association of nurse understaffing and limited work experience with the risk of an HAI 2 days after exposure, adjusting for individual risk factors. We reported hazard ratios (HRs) with 95% CIs. RESULTS: Neither nurse understaffing nor limited work experience were associated with the overall risk of HAIs. The results were inconsistent across staffing measures and types of HAIs, and many of the associations were weak. Regarding specific HAI types, 1-day exposure to low proportion of nurses with >3 years of in-hospital experience and low proportion of nurses more than 25 years old were associated with increased risk of bloodstream infections (HR=1.30; 95% CI: 1.04-1.62 and HR=1.40; 95% CI: 1.07-1.83). Two-day exposure to low nursing hours relative to target hours was associated with an increased risk of surgical-site infections (HR=2.64, 95% CI: 1.66-4.20). CONCLUSIONS: Data from time-varying analyses suggest that nursing staff shortages and limited work experience do not always increase the risk of HAI among patients.

Improving hand hygiene of young children with a digital intervention: a cluster-randomised controlled field trial.

Contagious diseases that affect young children place a great burden on them and their families. Proper hand hygiene is an important measure to reduce the disease burden, however, its implementation in day care centres is challenging. This paper introduces a digital intervention to support independent and good handwashing among young children. The intervention leverages animated instructions triggered by water and soap use, together with a symbolic reward shown to children on a screen during and immediately after handwashing. We tested the intervention in a pre-registered, cluster-randomised controlled field trial in 4 day care centres in Finland and Germany with 162 children over 42 days. The intervention increased soaping time, used as a proxy for handwashing quality, by 5.30 s (+ 62%, p < 0.001). The effect occurs immediately at the onset of the intervention and is maintained throughout the intervention phase.

Action research on promoting hand hygiene practices in an intensive care unit.

AIM: Evaluate the intensive care acquired infections incidence and the change over time in infection practices in one intensive care unit. DESIGN: We used an action research approach with cyclical activities. METHODS: Our study included two cycles with hand hygiene observation based on the WHO's five-moments observation tool, observing hand hygiene practices, analysing the observations, and giving feedback on observations, intensive care acquired infection rates, and alcohol-based hand rub consumption. The Revised Standards for Quality Improvement Reporting Excellence is the basis for this research report describing research aimed at improving patient safety and quality of care. RESULTS: During the study, annual alcohol-based hand rub consumption increased by 6.7 litres per 1000 patient days and observed hand hygiene compliance improved. In the first cycle of the study, there was a decrease in critical care acquired infection rates, but the improvement was not sustainable.

Hand hygiene of kindergarten children-Understanding the effect of live feedback on handwashing behaviour, self-efficacy, and motivation of young children: Protocol for a multi-arm cluster randomized controlled trial.

Early implementation of interventions at a young age fosters behaviour changes and helps to adopt behaviours that promote health. Digital technologies may help to promote the hand hygiene behaviour of children. However, there is a lack of digital feedback interventions focusing on the hand hygiene behaviour of preschool children in childhood education and care settings. This study protocol aims to describe a study that evaluates the effectiveness of a gamified live feedback intervention and explores underlying behavioural theories in achieving better hand hygiene behaviour of preschool children in early childhood education and care settings. This study will be a four-arm cluster randomized controlled trial with three phases and a twelve-month follow-up by country stratification. The sample size is 106 children of which one cluster will have a minimum number of 40 children. During the baseline phase, all groups will have automated monitoring systems installed. In the intervention phase, the control group will have no screen activity. The intervention groups will have feedback displays during the handwashing activity. Intervention A will receive instructions, and intervention B and C groups will receive instructions and a reward. In the post-intervention phase, all the groups will have no screen activity except intervention C which will receive instructions from the screen but no reward. The outcome measures will be hand hygiene behaviour, self-efficacy, and intrinsic motivation. Outcome measures will be collected at baseline, intervention, and post-intervention phases and a 12-month follow-up. The data will be analysed with quantitative and qualitative methods. The findings of the planned study will provide whether this gamified live feedback intervention can be recommended to be used in educational settings to improve the hand hygiene behaviour of preschool children to promote health. The trial is registered with ClinicalTrials.gov (registration number NCT05395988 https://clinicaltrials.gov/ct2/show/NCT05395988?term=NCT05395988&draw=2&rank=1).

Assisting nurses in care documentation: from automated sentence classification to coherent document structures with subject headings.

BACKGROUND: Up to 35% of nurses' working time is spent on care documentation. We describe the evaluation of a system aimed at assisting nurses in documenting patient care and potentially reducing the documentation workload. Our goal is to enable nurses to write or dictate nursing notes in a narrative manner without having to manually structure their text under subject headings. In the current care classification standard used in the targeted hospital, there are more than 500 subject headings to choose from, making it challenging and time consuming for nurses to use. METHODS: The task of the presented system is to automatically group sentences into paragraphs and assign subject headings. For classification the system relies on a neural network-based text classification model. The nursing notes are initially classified on sentence level. Subsequently coherent paragraphs are constructed from related sentences. RESULTS: Based on a manual evaluation conducted by a group of three domain experts, we find that in about 69% of the paragraphs formed by the system the topics of the sentences are coherent and the assigned paragraph headings correctly describe the topics. We also show that the use of a paragraph merging step reduces the number of paragraphs produced by 23% without affecting the performance of the system. CONCLUSIONS: The study shows that the presented system produces a coherent and logical structure for freely written nursing narratives and has the potential to reduce the time and effort nurses are currently spending on documenting care in hospitals.

Work hours, work stress, and collaboration among ward staff in relation to risk of hospital-associated infection among patients.

OBJECTIVES: To examine the association between work hours, work stress, and collaboration among the ward personnel, and the risk of hospital-associated infection among patients. DESIGN: Cross-sectional data on hospital infections were collected between March and June 2004. These data were linked with ward-level responses to a personnel survey collected during the same time period. SETTING: Medical records of patients in 60 non-psychiatric bed wards in 6 Finnish hospitals. PARTICIPANTS: One thousand ninety-two patients and 1159 staff survey responses. MEASUREMENTS: Prevalence surveillance was performed by 4 infection control nurses, using standard criteria. Data on several potential risk factors for infection were collected: sex, age, patient type (surgical vs. other), hospital type (university vs. regional hospital), unit type, number of patients in the ward, exposure to invasive devices, International Classification of Diseases version 10 diagnosis, chemotherapy, radiotherapy, and use of corticosteroids. Staff working conditions were measured by survey scales. RESULTS: Ninety-nine cases (9.1%) of hospital-associated infection were found. Multilevel logistic regression analyses, adjusted for hospital factors and patient-related risk factors, showed that long work hours among staff were associated with increased risk of infection [odds ratio (OR) 2.74, 95% confidence interval (CI): 1.07-7.04]. Other staff-related correlates of infection were high work stress, as indicated by high imbalance between efforts and rewards (OR: 2.47; 95% CI: 1.38-4.42), low trust between work unit members (OR: 2.37; 95% CI: 1.27-4.43), injustice in the distribution of work (OR: 1.81; 95% CI: 1.04-3.16), and poor collaboration between ward supervisors (OR: 2.46; 95% CI: 1.38-4.38). CONCLUSIONS: Long work hours, high work stress, and poor collaboration among the ward staff are associated with hospital-associated infection among patients.

Patient overcrowding in hospital wards as a predictor of diagnosis-specific mental disorders among staff: a 2-year prospective cohort study.

OBJECTIVE: Hospital ward patient overcrowding has been hypothesized to increase psychiatric morbidity among staff, but it is unknown whether the association is specific to depressive disorders. This study examined whether patient overcrowding in hospital wards predicts diagnosis-specific mental disorders among staff. METHOD: A 2-year prospective cohort study was conducted, in which the extent of hospital ward overcrowding was determined using routinely recorded patient bed occupancy rates between 2003 and 2004 and linked to sickness absence for 5,166 nurses and physicians in 203 somatic illness wards in 16 Finnish acute-care hospitals. Medically certified long-term (> 9 days) sickness absence spells in 2004 and 2005 with physician-determined diagnosis (based on ICD-10 criteria) were obtained from the register of the Social Insurance Institution of Finland. RESULTS: Cox proportional hazard models for recurrent events adjusted for sex, age, occupation, type and length of employment contract, hospital district, and specialty showed that health professionals working in wards with a patient occupancy level 10 percentage units above the optimal during a 1-year period experienced twice the risk of sickness absence due to depressive disorders (HR = 1.95; 95% CI, 1.18-3.24) relative to colleagues working in wards with optimal or below-occupancy levels. No significant association was found for diagnoses of severe stress and adjustment disorders or other psychiatric disorders. CONCLUSIONS: Chronic workload, as expressed by patient overcrowding in hospital wards, is associated with the onset of depressive disorders among staff.

Microbiological efficacy and tolerability of a new, non-alcohol-based hand disinfectant.

OBJECTIVE: Alcohol-based hand disinfectants are widely used in hospitals. Occasionally, there is a need for non-alcohol-based products, but alternatives have been scarce. We studied the microbiological efficacy and tolerability of a water-based hand disinfectant for healthcare workers. DESIGN: A water-based hand disinfectant was introduced as the only hand disinfectant in 5 wards in Turku University Hospital, Finland. Ninety-nine healthcare workers participated in fingerprint sampling during the 7-week study period. In another ward, 26 healthcare workers who were using alcohol-based hand disinfectant acted as control subjects for the skin reaction studies. The water-based product was tested in the laboratory according to the European standard EN 12791. We obtained 292 fingerprint samples before disinfection and 302 after disinfection. The opinions of healthcare workers were collected by use of a questionnaire, and skin reactions were assessed subjectively by use of questionnaires and objectively by measuring moisture and transepidermal water loss. RESULTS: When tested in accordance with the European standard, the product met the requirements for short-term and long-term efficacy. The results of the fingerprint test showed that there was a statistically significant decrease in colonization of the fingertips before and after disinfection (P<.001). The users of the water-based hand disinfectant reported dry skin more often than did control subjects, but visual inspection and the results of the moisture measurement showed no difference between the users of the water-based hand disinfectant and the control subjects. Transepidermal water loss measurement also showed no deterioration of skin condition. CONCLUSIONS: The water-based hand disinfectant was shown to be an effective hand disinfectant that caused relatively little skin irritation and can serve as a hand hygiene alternative in situations in which alcohol-based disinfectant cannot be used.

Overcrowding in hospital wards as a predictor of antidepressant treatment among hospital staff.

OBJECTIVE: This report assessed whether hospital ward overcrowding predicts antidepressant use among hospital staff. METHOD: The extent of hospital ward overcrowding was determined using administrative records of monthly bed occupancy rates between 2000 and 2004 in 203 somatic illness wards in 16 Finnish hospitals providing specialized health care. Information on job contracts for personnel was obtained from the employers' registers. Comprehensive daily data on purchased antidepressant prescriptions (World Health Organization's Anatomical Therapeutic Chemical classification code N06A) for nurses (N=6,699) and physicians (N=641) was derived from national registers. Cox proportional hazards models were used to examine the association between bed occupancy rate and subsequent antidepressant treatment. Monthly bed occupancy rates were used as a time-dependent exposure that could change in value over the course of observation. Hazard ratios were adjusted for sex, age, occupation, type and length of employment contract, hospital district, specialty, and calendar year. RESULTS: Exposure over 6 months to an average bed occupancy rate over 10% in excess of the recommended limit was associated with new antidepressant treatment. This association followed a dose-response pattern, with increasing bed occupancy associated with an increasing likelihood of antidepressant use. There was no evidence of reverse causality; antidepressant treatment among employees did not predict subsequent excess bed occupancy. CONCLUSIONS: The increased risk of antidepressant use observed in this study suggests that overcrowding in hospital wards may have an adverse effect on the mental health of staff.
