Intrahospital transfers and adverse patient outcomes: An analysis of administrative health data

Nurse/midwife-to-patient ratios: A scoping review

BACKGROUND

A significant body of work has linked high nurse or midwife workload to negative patient outcomes. Anecdotal reports suggest that mandated ratio models enhance patient care and improve nurse job satisfaction. However, there is limited focused research.

OBJECTIVE

To identify key outcomes, implementation processes, and research needs regarding nurse/midwife-to-patient ratios in the Australian healthcare context.

DESIGN

Scoping review.

METHODS

Data sources were CINAHL, Open Dissertations, Medline, and Scopus. 289 articles screened, and 53 full text documents independently assessed against criteria by two reviewers and conflicts resolved by a third reviewer, using Covidence™. Three studies were included in this review.

RESULTS

Studies focused on nurse (job satisfaction, burnout), patient (mortality, readmission, length of stay) and system (costs) outcomes with limited information on implementation processes and no midwifery research.

CONCLUSIONS

Ratios provide benefits for patients, nurses, and hospitals although there is limited research in Australia. Implementation was poorly reported..

The impact of atypical intrahospital transfers on patient outcomes: a mixed methods study

The architectural design of hospitals worldwide is centred around individual departments, which require the movement of patients between wards. However, patients do not always take the simplest route from admission to discharge, but can experience convoluted movement patterns, particularly when bed availability is low. Few studies have explored the impact of these rarer, atypical trajectories. Using a mixed-method explanatory sequential study design, we firstly used three continuous years of electronic health record data prior to the Covid-19 pandemic, from 55,152 patients admitted to a London hospital network to define the ward specialities by patient type using the Herfindahl-Hirschman index. We explored the impact of 'regular transfers' between pairs of wards with shared specialities, 'atypical transfers' between pairs of wards with no shared specialities and 'site transfers' between pairs of wards in different hospital site locations, on length of stay, 30-day readmission and mortality. Secondly, to understand the possible reasons behind atypical transfers we conducted three focus groups and three in-depth interviews with site nurse practitioners and bed managers within the same hospital network. We found that at least one atypical transfer was experienced by 12.9% of patients. Each atypical transfer is associated with a larger increase in length of stay, 2.84 days (95% CI 2.56-3.12), compared to regular transfers, 1.92 days (95% CI 1.82-2.03). No association was found between odds of mortality, or 30-day readmission and atypical transfers after adjusting for confounders. Atypical transfers appear to be driven by complex patient conditions, a lack of hospital capacity, the need to reach specific services and facilities, and more exceptionally, rare events such as major incidents. Our work provides an important first step in identifying unusual patient movement and its impacts on key patient outcomes using a system-wide, data-driven approach. The broader impact of moving patients between hospital wards, and possible downstream effects should be considered in hospital policy and service planning.

Mixed-methods study examining family carers' perceptions of the relationship between intrahospital transitions and patient readiness for discharge

INTRODUCTION

Intrahospital transitions (IHTs) represent movements of patients during hospitalisation. While transitions are often clinically necessary, such as a transfer from the emergency department to an intensive care unit, transitions may disrupt care coordination, such as discharge planning. Family carers often serve as liaisons between the patient and healthcare professionals. However, carers frequently experience exclusion from care planning during IHTs, potentially decreasing their awareness of patients' clinical status, postdischarge needs and carer preparation. The purpose of this study was to explore family carers' perceptions about IHTs, patient and carer ratings of patient discharge readiness and carer self-perception of preparation to engage in at home care.

METHODS

Sequential, explanatory mixed-methods study involving retrospective analysis of hospital inpatients from a parent study (1R01HS026248; PI Wallace) for whom patient and family carer Readiness for Hospital Discharge Scale (RHDS) score frequency of IHTs and patient and caregiver characteristics were available. Maximum variation sampling was used to recruit a subsample of carers with diverse backgrounds and experiences for the participation in semistructured interviews to understand their views of how IHTs influenced preparation for discharge.

RESULTS

Of discharged patients from July 2020 to April 2021, a total of 268 had completed the RHDS and 23 completed the semistructured interviews. Most patients experienced 0-2 IHTs and reported high levels of discharge readiness. During quantitative analysis, no association was found between IHTs and patients' RHDS scores. However, carers' perceptions of patient discharge readiness were negatively associated with increased IHTs. Moreover, non-spouse carers reported lower RHDS scores than spousal carers. During interviews, carers shared barriers experienced during IHTs and discussed the importance of inclusion during discharge care planning.

CONCLUSIONS

IHTs often represent disruptive events that may influence carers' understanding of patient readiness for discharge to home and, thus, their own preparation for discharge. Further consideration is needed regarding how to support carers during IHT to facilitate high-quality discharge planning.

Implementation fidelity of a multifactorial in-hospital fall prevention program and its association with unit systems factors: a single center, cross-sectional study

BACKGROUND

Falls are a common, costly global public health burden. In hospitals, multifactorial fall prevention programs have proved effective in reducing falls' incidence; however, translating those programs accurately into daily clinical practice remains challenging. This study's aim was to identify ward-level system factors associated with implementation fidelity to a multifactorial fall prevention program (StuPA) targeting hospitalized adult patients in an acute care setting.

METHODS

This retrospective cross-sectional study used administrative data on 11,827 patients admitted between July and December 2019 to 19 acute care wards at the University Hospital Basel, Switzerland, as well as data on the StuPA implementation evaluation survey conducted in April 2019. Data were analysed using descriptive statistics, Pearson's coefficients and linear regression modelling for variables of interest.

RESULTS

The patient sample had an average age of 68 years and a median length of stay of 8.4 (IQR: 2.1) days. The mean care dependency score was 35.4 points (ePA-AC scale: from 10 points (totally dependent) to 40 points (totally independent)); the mean number of transfers per patient -(e.g., change of room, admission, discharge) was 2.6 (range: 2.4- 2.8). Overall, 336 patients (2.8%) experienced at least one fall, resulting in a rate of 5.1 falls per 1'000 patient days. The median inter-ward StuPA implementation fidelity was 80.6% (range: 63.9-91.7%). We found the mean number of inpatient transfers during hospitalisation and the mean ward-level patient care dependency to be statistically significant predictors of StuPA implementation fidelity.

CONCLUSION

Wards with higher care dependency and patient transfer levels showed higher implementation fidelity to the fall prevention program. Therefore, we assume that patients with the highest fall prevention needs received greater exposure to the program. For the StuPA fall prevention program, our results suggest a need for implementation strategies contextually adapted to the specific characteristics of the target wards and patients.

Enhancement of Intra-hospital patient transfer in medical center hospital using discrete event system simulation

The intra-hospital transfer of critically ill patients are associated with complications at up to 70%. Numerous issues can be avoided with optimal pre-transport planning and communication. Simulation models have been demonstrated to be an effective method for modeling processes and enhancing on-time service and queue management. Discrete-event simulation (DES) models are acceptable for general hospital systems with increased variability. Herein, they are used to improve service effectiveness. A prospective observational study was conducted on 13 official day patient transfers, resulting in a total of 827 active patient transfers. Patient flow was simulated using discrete-event simulation (DES) to accurately and precisely represent real-world systems and act accordingly. Several patient transfer criteria were examined to create a more realistic simulation of patient flow. Waiting times were also measured to assess the efficiency of the patient transfer process. A simulation was conducted to identify 20 scenarios in order to discover the optimal scenario in which where the number of requests (stretchers or wheelchairs) was increased, while the number of staff was decreased to determine mean waiting times and confidence intervals. The most effective approach for decreasing waiting times involved prioritizing patients with the most severe symptoms. After a transfer process was completed, staff attended to the next transfer process without returning to base. Results show that the average waiting time was reduced by 21.78% which is significantly important for emergency cases. A significant difference was recorded between typical and recommended patient transfer processes when the number of requests increased. To decrease waiting times, the patient transfer procedure should be modified according to our proposed DES model, which can be used to analyze and design queue management systems that achieve optimal waiting times.

Isolation precautions cause minor delays in diagnostics and treatment of non-COVID patients

Background

Isolation precautions are essential prevent spread of COVID-19 infection but may have a negative impact on inpatient care. The impact of these measures on non-COVID-19 patients remains largely unexplored.

Aim

This study aimed to investigate diagnostic and treatment delays related to isolation precautions, the associated patient outcome, and the predisposing risk factors for delays.

Methods

This observational study was conducted in seven Helsinki region hospitals during the first wave of the COVID-19 pandemic in Finland. The study used data on all non-COVID-19 inpatients, who were initially isolated due to suspected COVID-19, to estimate whether isolation precautions resulted in diagnostic or treatment delays.

Results

Out of 683 non-COVID-19 patients, 33 (4.8%) had delays related to isolation precautions. Clinical condition deteriorated non-fatally in seven (1.0%) patients. The following events were associated with an increased risk of treatment or a diagnostic delay: more than three ward transfers (P = 0.025); referral to an incorrect speciality in the emergency department (P = 0.004); more than three SARS-CoV-2 RT-PCR tests performed (P = 0.022); and where cancer was the final diagnosis (P = 0.018). In contrast, lower respiratory tract symptoms (P = 0.013) decreased the risk.

Conclusions

The use of isolation precautions for patients who did not have COVID-19 had minor negative effects on patient outcomes. The present study underlines the importance of targeting diagnostic efforts to patients with unspecified symptoms and to those with a negative SARS-CoV-2 test result. Thorough investigations to achieve an accurate diagnosis improves the prognosis of patients and facilitates appropriate targeting of hospital resources.

Within-unit bed moves in a short-stay in-patient unit are associated with increased falls

Objective This study evaluated a patient's likelihood of a fall using information available at the time of presentation to a short-stay acute medical unit (AMU) with a high patient turnover rate and estimated the effect of within-unit bed moves on the occurrence of in-patient falls. Methods This study was a 3-year retrospective cross-sectional study of 28713 consecutive admissions comparing patients who fell and patients who did not fall. Factors assessed included premorbid falls risk factors, presenting issues and within-unit bed moves. Logistic regression was used to identify factors associated with patients who fell. Each admission was treated as a unit of measure. Results Of 28713 admissions, 182 (0.6%) involved at least one fall event. The fall rate was 5.67 falls per 1000 occupied bed days. Premorbid cognitive impairment (odds ratio (OR) 4.88), a presenting issue of confusion (OR 2.92) and a fall immediately before admission (OR 2.49) were associated with patients who fell (all P<0.001). Each bed move corresponded to a 27% increase in the odds of a fall (OR 1.27; P=0.027). Conclusion Premorbid cognitive impairment was the strongest risk factor for an in-patient fall on the unit. Within-unit bed moves significantly increased the risk of an in-patient fall and should be minimised. What is known about the topic? In-patient falls can cause significant patient harm at cost to the health system. There is limited research examining the association between within-unit bed moves and falls in a short-stay AMU. What does this paper add? Care in the short-stay AMU is complex and the number of bed moves is a modifiable factor that can reduce a patient's risk of an in-patient fall. What are the implications for practitioners? Bed moves need to be minimised, especially for patients with cognitive impairment. If bed moves are inevitable, operational plans can be designed to mitigate the increased risk caused by these moves.

Transfer of patients in hospital units: impacts on nursing workload

OBJECTIVE

To measure the average time spent by the nursing team in transferring patients; to compare the activities observed during the performance of this intervention with those described by the Nursing Interventions Classification and to investigate the intensity of its influence on the workload.

METHOD

Observational study using timekeeping software conducted in two hospitals in the northwest region of the State of São Paulo. 200 patient transfers were monitored by the team using two validated instruments.

RESULTS

The average time spent by nurses on transfers ranged from 9.3 (standard deviation = 3.5) to 12.2 (standard deviation = 2.5) minutes and by assistants/ technicians between 7.1 (standard deviation = 2,8) and 11.0 (standard deviation = 2.2) minutes. 63 transfers made by nurses and 87 by assistants/technicians were considered qualified (>70% of the score). The team expended 19.3 to 29% of the working day time in this intervention.

CONCLUSION

The transfer of patients has an impact on the workload of the team and needs to be considered in the measurement of nursing activities for the calculation and distribution of personnel to improve the quality and continuity of care.

Exploring nurses' clinical reasons for bed transfers in acute care wards: An observational study

AIMS

To investigate the number of bed transfers (patient transfers within the same ward) and their reasons in acute care wards of mid-sized hospitals with multibed and private rooms.

BACKGROUND

Bed transfers, even when necessary, are burdensome for patients; however, the reasons for bed transfers in various types of rooms remain unclear.

METHODS

An observational study was conducted in seven wards in three hospitals in Japan. Nurses completed a questionnaire regarding each bed transfer, which elicited the reasons for the transfer. We classified transfer patterns based on the functions of the patients' rooms and the number of beds in each room and analysed scores.

RESULTS

Overall, 560 responses were analysed. The average number of bed transfers per day was 2.7. In total, 43% of bed transfers were conducted for patients aged over 70. The most frequent bed transfer pattern was 'transfer between patient rooms with the same number of beds', and the most frequent reason was 'patient did not need that bed'.

CONCLUSIONS

Unnecessary bed transfers could be reduced by ward designs that reflect nurses' clinical judgement.

IMPLICATIONS FOR NURSING MANAGEMENT

Monitoring data for the reason regarding bed transfer contributes to hospital planning and decreases unnecessary bed transfers.

Impact of weekend admission and changes in treating team on patient flow and outcomes in adults admitted to hospital with community-acquired pneumonia

BACKGROUND

The effect of workflow factors, such as timing of admission and changes in treating team, on patient outcomes remains inconclusive.

AIMS

To investigate the impact of weekend admission and changes in treating team on four pre-defined outcomes in patients admitted to hospital with community-acquired pneumonia (CAP).

METHODS

We performed an observational cohort study by utilising prospective longitudinal data collected during the IMPROVE-GAP trial, a stepped-wedge randomised study investigating an evidence-based bundle of care in the management of CAP. We assessed the effect of two exposure variables, day of admission and change of treating team, on four pre-specified outcomes: (i) length of stay; (ii) time to clinical stability; (iii) readmission within 30 days; and (iv) mortality at 30 days. Our analysis was restricted to patients with a primary diagnosis of CAP and employed multivariable Cox regression and logistic regression to adjust for potential measured confounders.

RESULTS

Of 753 participants, 224 (29.7%) were admitted on the weekend and 71 (9.4%) changed treating team during admission. Weekend admissions had significantly longer hospital stays than weekday admissions (hazard ratio (95% confidence interval; P-value) 0.82 (0.70-0.98; 0.03)) and took longer to reach clinical stability (0.80 (0.68-0.95; 0.01)). Change of treating team doubled the odds of readmission at 30 days (odds ratio 1.95 (1.08-3.58; 0.03)).

CONCLUSIONS

These results suggest workflow factors can negatively impact both health service and patient outcomes. Systems interventions aimed at improving out of hours service and reducing changes in treating team should be considered.

Association between intrahospital transfer and hospital-acquired infection in the elderly: a retrospective case-control study in a UK hospital network

Background

Intrahospital transfers have become more common as hospital staff balance patient needs with bed availability. However, this may leave patients more vulnerable to potential pathogen transmission routes via increased exposure to contaminated surfaces and contacts with individuals.

Objective

This study aimed to quantify the association between the number of intrahospital transfers undergone during a hospital spell and the development of a hospital-acquired infection (HAI).

Methods

A retrospective case–control study was conducted using data extracted from electronic health records and microbiology cultures of non-elective, medical admissions to a large urban hospital network which consists of three hospital sites between 2015 and 2018 (n=24 240). As elderly patients comprise a large proportion of hospital users and are a high-risk population for HAIs, the analysis focused on those aged 65 years or over. Logistic regression was conducted to obtain the OR for developing an HAI as a function of intrahospital transfers until onset of HAI for cases, or hospital discharge for controls, while controlling for age, gender, time at risk, Elixhauser comorbidities, hospital site of admission, specialty of the dominant healthcare professional providing care, intensive care admission, total number of procedures and discharge destination.

Results

Of the 24 240 spells, 2877 cases were included in the analysis. 72.2% of spells contained at least one intrahospital transfer. On multivariable analysis, each additional intrahospital transfer increased the odds of acquiring an HAI by 9% (OR=1.09; 95% CI 1.05 to 1.13).

Conclusion

Intrahospital transfers are associated with increased odds of developing an HAI. Strategies for minimising intrahospital transfers should be considered, and further research is needed to identify unnecessary transfers. Their reduction may diminish spread of contagious pathogens in the hospital environment.

A Systematic Review of Clinical Outcomes Associated With Intrahospital Transitions

Previous transitional care research has focused on transitions occurring between community and hospital settings. Little is known regarding intrahospital transitions and how they affect care quality. A systematic review was therefore conducted to synthesize the literature regarding clinical outcomes associated with intrahospital transitions. Literature published between January 2003 and December 2018 and indexed in Medline/PubMed, CINAHL, and PsychINFO were reviewed using PRISMA guidelines. Articles were limited to English language and peer-reviewed. Articles were excluded if they focused on transitions occurring from or to the hospital, discharge/discharge planning, or postdischarge follow-up. Data abstraction included study characteristics, sample characteristics, and reported clinical outcomes. Fourteen studies met inclusion criteria, primarily using cross-sectional, cohort, or retrospective chart review quantitative designs. Data were analyzed and synthesized based on outcomes reported. Major outcomes emerging from the articles included delirium, hospital length of stay, mortality, and adverse events. Delirium, hospital length of stay, and morbidity and mortality rates were associated with delayed transfers and transfers to inappropriate units. In addition, increased fall risk and infection rates were associated with higher rates of transfer. Intrahospital transitions represent critical periods of time where the quality of care being provided may be diminished, negatively affecting patient safety and outcomes.

Shadowing to Improve Teamwork and Communication:

Teamwork and communication are paramount to patient safety. Poor communication during handoff is implicated in near misses and adverse events. Exposing nurses to other units’ workflow early in their orientation may also aid in surge staffing. This study showed improvements in teamwork and communication, and a deeper understanding of another units’ workflow.

The Relationship Between Hospital Interdepartmental Transfers and Patient Experience

This study examined the association between interdepartmental transfers and the perceptions of care received by adult patients who were admitted and discharged from a 300-bed, not-for-profit community tertiary hospital in the Midwest. Transfers of patient care are daily and frequent hospital processes. However, limited attention has focused on the effect that intrahospital transfers of care have on the patient experience. Understanding this relationship is important, since value-based purchasing models directly tie patient experience measures into hospital reimbursements. The key finding of this study indicates that as patients' transfers increase, their perceptions of care decrease. Therefore, by reducing the frequency of interdepartmental transfers, patient satisfaction may increase. This research provides clinicians and administrators a better understanding of the relationship between a frequent and a daily hospital process (ie, interdepartmental transfers) and its influence on patients' perceptions of their experience.

Organisational factors underpinning intra-hospital transfers: a guide for evaluating context in quality improvement

During intra-hospital transfers, multiple clinicians perform coordinated tasks that leave patients vulnerable to undesirable outcomes. Communication has been established as a challenge to care transitions, but less is known about the organisational complexities within which transfers take place. We performed a qualitative assessment that included various professions to capture a multi-faceted understanding of intra-hospital transfers. Ethnographic observations and semi-structured interviews were conducted with clinicians and staff from the Medical Intensive Care Unit, Emergency Department, and general medicine units at a large, urban, academic, tertiary medical centre. Results highlight the organisational factors that stakeholders view as important for successful transfers: the development, dissemination, and application of protocols; robustness of technology; degree of teamwork; hospital capacity; and the ways in which competing hospital priorities are managed. These factors broaden our understanding of the organisational context of intra-hospital transfers and informed the development of a practical guide that can be used prior to embarking on quality improvement efforts around transitions of care.

Geriatric nurse involvement during intra-hospital transitions

Geriatric nurses are skilled in the special needs of hospitalized older adults. While significant focus has been placed on improving care transitions upon discharge, less attention has been placed on intra-hospital transitions. Intra-hospital transitions represent transfers occurring between hospital units or rooms. Intra-hospital transitions challenge normal nursing workflow and require careful consideration of care coordination to prevent adverse events for older adults. Frequent changes in environment and a lack of consistency in care may support the development or prolongation of delirium as older adults are transferred between units and rooms. Additional adverse event risks include infections and falls, which also increases with each transfer. Geriatric nurse involvement can enhance communication between units as well as ensuring appropriate geriatric assessments occur. Geriatric nurses are thus well positioned to act as leaders during intra-hospital transitions, potentially reducing these and adverse events.

Improving the Hospital Quality of Care during Winter Periods by Optimizing Budget Allocation Between Rotavirus Vaccination and Bed Expansion

BACKGROUND

During each winter the hospital quality of care (QoC) in pediatric wards decreases due to a surge in pediatric infectious diseases leading to overcrowded units. Bed occupancy rates often surpass the good hospital bed management threshold of 85%, which can result in poor conditions in the workplace. This study explores how QoC-scores could be improved by investing in additional beds and/or better vaccination programs against vaccine-preventable infectious diseases.

METHODS

The Cobb-Douglas model was selected to define the improvement in QoC (%) as a function of two strategies (rotavirus vaccination coverage [%] and addition of extra hospital beds [% of existing beds]), allowing improvement-isocurves to be produced. Subsequently, budget minimization was applied to determine the combination of the two strategies needed to reach a given QoC improvement at the lowest cost. Data from Jessa Hospital (Hasselt, Belgium) were chosen as an example. The annual population in the catchment area to be vaccinated was 7000 children; the winter period was 90 days with 34 pediatric beds available. Rotavirus vaccination cost per course was €118.26 and the daily cost of a pediatric bed was €436.53. The target QoC increase was fixed at 50%. The model was first built with baseline parameter values.

RESULTS

The model predicted that a combination of 64% vaccine coverage and 39% extra hospital beds (≈ 13 extra beds) in winter would improve QoC-scores by 50% for the minimum budget allocation.

CONCLUSION

The model allows determination of the most efficient allocation of the healthcare budget between rotavirus vaccination and bed expansion for improving QoC-scores during the annual epidemic winter seasons.
