Quantitative evaluation of clinical pharmacy activities following implementation of an enhanced weekend service at a teaching hospital

Abstract Introduction Improving equity of staffing across seven-days is a strategic priority for the National Health Service (NHS).1 Development of enhanced weekend clinical pharmacy services presents opportunity to improve admission and discharge medicines reconciliation (MR), reduce medication error and increase patient counselling.2 At the study site, an enhanced weekend clinical pharmacy service was implemented in October 2021. The service was delivered 9am-5pm to all clinical specialities across 54 wards. Defined minimum staffing was 13 pharmacists and 2 medicines management pharmacy technicians (MMPT). Service specification included: clinical screen and order of medications; admission MR, review of high-risk patients (critical care patients and those prioritised by the weekday team); and discharge activities including patient counselling. Aim To evaluate provision of the enhanced weekend clinical pharmacy service post-implementation by quantification of shift fill and clinical pharmacy professional activities. Methods A quantitative study was conducted over two separate weekends one month and six months post-implementation (13th-14th November 2021 and 9-10th April 2022). Pharmacy professionals collected data using a paper activity tool validated for use at the study site. Interventions included rectification of medication error, medicines optimisation or consult. Data were collated in Microsoft Excel immediately after each study weekend. Simple descriptive statistics were performed in Microsoft Excel. The study was registered with KCH Pharmacy Research and Audit Group (07/2021), deemed service evaluation and ethics approval waived. Results Pharmacy professionals reviewed 1,056 patients over 3,645 occupied bed-days. Services were delivered by 13 pharmacists and 1 MMPT on weekend 1, 12 pharmacists and 1 MMPT on weekend 2. Data were collected for all wards on weekend 1; on weekend 2 activity data was not collected for five surgical wards (Saturday and Sunday), four post-acute medical wards (Saturday) and the acute medical unit (Sunday). Admission MR was conducted for 77% (317/412) of newly-admitted patients. Pharmacists recommended prescription amendment for 68% (217/317) of patients receiving admissions MR; affecting 517 medicines. The recorded intervention rate per patient reviewed was 0.64 (680/1056). Pharmacy professionals responded to 211 queries from healthcare professionals (HCPs), undertook 90 incidences of pro-active HCP education and counselled 92 patients/carers. Pharmacists prepared discharge medication lists or clinically screened discharge prescriptions for 205 patients. A total of 952 non-stock medicines were ordered and 313 patients own medicines checked for suitability for reuse. Discussion / Conclusion These findings add to existing evidence for seven-day clinical pharmacy services. Defined minimum staffing was not fulfilled with 90% shift fill rate. Clear benefit was demonstrated in terms of admission MR and resultant intervention, HCP education, discharge and counselling activities. The percentage of patients with a recommended prescription amendment following admission MR matched findings from a separate service evaluation during February 2021 of an enhanced weekend service introduced at our study site during the COVID-19 pandemic (68%).3 The intervention rate for reviewed patients was also comparable (0.64 compared with 0.57 during COVID-19).3 Limitations include the relatively short period of data collection at a single-site which limits generalisability of findings. There were some gaps in data collection and acceptance rate of interventions was not collected.

Implementation of Medical Hospitalist Care at a Korean Tertiary Hospital: A Retrospective Cross-Sectional Study.

Background/Objectives: In March 2018, a tertiary teaching hospital launched a medical hospitalist team. This study presents the clinical characteristics and outcomes of medical hospitalist care and reveals the relationship between them. Methods: This study included 4003 patients first admitted to the hospitalist team via emergency room and then discharged from the hospitalist team between March 2018 and November 2022. The patients were admitted either to the teaching admitter hospitalist team or the hospitalist-led acute medical unit (AMU). Afterward, the patients were either discharged, if possible, within a few days or transferred to ward hospitalists if assigned wards for hospitalist care were available. Results: The patients' mean Charlson Comorbidity Index score was 3.5 and the mean National Early Warning Score was 3.4. Of the admissions, 44.2% of the patients were admitted to the AMU, and 26.8% received an early consultation with a subspecialist. Each hospitalist managed 12.8 patients per month on average. The patients' mean LOS was 14.52 days, 10.5% of patients died during hospitalization, and 13.0% of patients had unscheduled readmission within 1 month. The patients' mean total cost per hospital stay was 572,836 won per day. Admission to the AMU was associated with a lower total cost per hospital stay, but the relationships with mortality, readmission, and LOS were not significant. Conclusions: The study reports on the outcomes of implementing a medical hospitalist care system that combines short-term admission wards with integrated care models to manage complex cases. These findings provide insights into optimizing hospitalist systems for improved patient outcomes.

07 Partnering with patients with living and lived experience of eating disorders to improve inpatient care on an acute paediatric medicine unit

Abstract Background Since the COVID-19 pandemic, hospitals nationally are seeing a growing number of adolescent patients with eating disorders requiring acute medical stabilization, which is often a time of crisis in the trajectory of this ego-syntonic disorder. The complexity of these admissions often lead to safety events for patients and moral distress for clinicians. Medical admissions can also be an opportunity to engage youth and families. Patient partners are a pillar in healthcare quality improvement, but historically we have not engaged adolescent patient partners in improving acute eating disorder treatment. We gathered the experience of patients and families with living and lived experience of eating disorder treatment to improve their quality of care in an acute paediatric medicine unit. Objectives We aimed to describe the experience of patients and families with living and lived experience of eating disorder treatment, specifically acute medical stabilization, through a quality improvement patient engagement project. Design/Methods We used a mixed-methods design of semi-structured interviews and a focus group with adolescents with eating disorders and their caregivers in an acute medical unit at a tertiary paediatric hospital in British Columbia. We employed opportunity sampling by distributing recruitment flyers through patient experience councils, outpatient clinics, other non-acute units, and to all patients admitted with a medically unstable eating disorder at our hospital during the study period. The interviews consisted of open-ended questions, yes/no questions, and Likert scales related to four categories: admission process, inpatient experience, team communication, and discharge process. Two reviewers analyzed the qualitative data using thematic analysis, and the quantitative data was analyzed descriptively. Quality improvement projects are exempt from Research Ethics Board approval. However, we utilized the "A Project Ethics Community Consensus Initiative" (ARECCI) Ethics Guideline and Screening Tool and presented our proposal at the hospital's quality improvement and research oversight committees. Results We completed 8 interviews with patients with current living experience admitted to our acute medical unit. We also completed 1 interview with a patient with past lived experience and 1 focus group with patients and caregivers. Primary themes identified included uncertainty about their overall treatment journey and stress due to the sudden new expectations on the inpatient unit, such as activity restriction, meal plans by the hospital, and bathroom access after meal times. Patients identified the importance of relational care, inclusion in treatment planning, acknowledgement of the demanding nature of eating disorders, and individualized care. Due to variability in training, resource allocation, and gaps in communication, these patient-identified priorities are not always met. While 100% of participants stated they understood the reasons and goals for admission, participants averaged 3.7 on a 1 (lowest) to 5 (highest) Likert scale when asked to rate their satisfaction with the information they received. Five out of eight adolescents felt that there was consistency in communication within the team. Conclusion We demonstrate the complex needs of patients with eating disorders who require acute medical stabilization. Targeted knowledge mobilization initiatives through admission orientation documents and family-centered rounds could better meet those needs. We are currently developing an admission pamphlet and journal for patients admitted with a new eating disorder to our medical unit. Patient partners exhibited a high willingness to participate in our study and readily acknowledged the importance their contributions could hold for other patients.

A New Hospital-At-Home Model for Integrated Geriatric Care: Data from a Preliminary Italian Experience

ObjectiveHospital-at-home (HaH) has emerged as an alternative to conventional in-hospital care in older adults, possibly reducing hospital admissions and related complications. This study aimed to describe the characteristics and outcomes of patients referred to “Gruppo di Intervento Rapido Ospedale-Territorio” (GIROT), a HaH service based on comprehensive geriatric assessment, developed in Florence, Italy, during the postpandemic period. DesignRetrospective longitudinal study. Setting and ParticipantsGIROT provided home-based care to patients with acute or exacerbated chronic diseases and a high risk of hospital-related complications (ie, patients with moderate-to-severe disability and/or dementia), referred from primary care, emergency departments, or in-hospital units. MethodsAll-cause mortality and hospitalization rates were assessed at 1, 3, and 6 months, and predictors of 6-month mortality were investigated. ResultsAmong 391 patients (mean age, 88.4 years; 62.4% female) referred from emergency departments (58.6%), primary care (27.9%), and acute medical units (13.6%), the main diagnoses were respiratory failure (28.4%), acute heart failure (25.3%), and delirium (13.6%). Patients referred from primary care were older and showed a higher prevalence of severe disability and hypomobility. After 1, 3, and 6 months, mortality rates were 34.5%, 45.6%, and 53.8%, and hospitalization rates 7.2%, 21.5%, and 37.9%, respectively. Predictors of 6-month mortality included age [odds ratio (OR), 1.039], severe disability (OR, 3.446), impossible/assisted walking (OR, 4.450) and referral from primary care (OR, 2.066). High global satisfaction with the service was reported. Conclusions and ImplicationsThe GIROT model may help expanding acute health care capacity for older adults at high risk of hospital-related complications. Customized care plans are needed in patients with severe disability/hypomobility, considering also simultaneous palliative care.

Nutritional screening on hospital admission and one-year clinical outcomes in a prospective cohort of older patients

Background & AimsMalnutrition negatively affects the prognosis and quality of life of hospitalized patients. However, there are several gaps between evidence-based knowledge and current clinical practice. Our primary aim was to describe the prevalence of malnutrition risk in a cohort of in a cohort of older inpatients; secondly, we explored its predictors and its independent impact on 12-month survival. MethodsProspective study focused on patients aged 65 years and older consecutively admitted for any reason to the acute geriatric and general medical units of an Italian university hospital. Comprehensive geriatric assessment data, including the short form of the Mini Nutritional Assessment (MNA-SF), were collected within 48 hours of admission. The prevalence of malnutrition and risk of malnutrition according to the MNA-SF represented the main outcome. Correlations among clinical variables, nutritional status, and one-year survival were analyzed using multivariable and Cox models. ResultsAmong 594 patients (median age: 84 years, 49.5% female), mostly living at home with moderate functional autonomy, 82.3% were identified as probably malnourished or at risk of malnutrition according to MNA-SF (39.9% and 42.4%, respectively). Malnutrition and the risk of malnutrition were positively associated with living alone at home (OR 2.803, 95%CI 1.567-5.177, p<0.001), and negatively associated with autonomy in IADL (OR 0.765, 95%CI 0.688-0.846, p<0.001) and the best performance at HST (OR 0.901, 95%CI 0.865-0.936; p<0.001). After 12 months, 31.8% of patients was dead and mortality was positively correlated with malnutrition according to MNA-SF (OR 2.493, 95%CI 1.345-4.751, p=0.004), institutionalization (OR 2.815, 95%CI 1.423-5.693, p=0.003) and severe cognitive impairment (OR 1.701, 95%CI 1.031-2.803, p=0.036). ConclusionMalnutrition is common among older inpatients upon admission, primarily influenced by their functional and cognitive status, and it is linked to a worse prognosis. Early incorporation of thorough nutritional and functional assessments into clinical practice is crucial to improve prognosis prediction and enable timely, focused interventions targeting modifiable causal factors in a patient-centered approach.

Impact of Geriatricians on the Outcome of Patients in the Acute Medical Unit at the Largest Acute Academic Teaching Hospital

Abstract Background The Acute Medical Unit (AMU) forms part of our institution's acute medical pathways. Through the Senior Intervention Flow Triage system in our Emergency Department (ED), medically stable patients likely to complete investigations and treatment within 48 to 72 hours are referred to the AMU for management. Acute medicine geriatricians cover three out of five days in the AMU. This paper aims to study the characteristics and outcomes of patients referred to our AMU. Methods Our institution’s innovation and research office approved the study, ref: 8731, on 24/01/2024. Medical notes from patients who attended the AMU from 11 December 2023 to 30 January 2024 were examined. Collected data included demographics, presenting complaints, admissions avoided and converts. Patients were divided into age groups: ≤64, 65-74, and ≥75. Admission avoidance is any intervention by the AMU that results in the patient's discharge. A convert is an on-call team medically admitted patient in the ED who was taken over and successfully discharged by the AMU with appropriate follow-up. Results 345 patients attended AMU over the six-week period. Of those, 217 (62.9%) were ≤64, 65 (18.8%) were 65-74, and 63 (18.3%) were ≥75 years old. More than 50% of the patients were female in each age group. The ≤ 64 years group had the highest admission avoidance, 72%, followed closely by the ≥ 75 years group, 65% and the 65-74 years group, 57%. The ≥ 75 years group had the highest rate of converts at 11%, followed by the ≤ 64 years group at 10% and the 65-74 years group at 6%. There were similar admission rates across the 3 age groups of 7 to 8%. Conclusion This study found that the ≥ 75-year-old group was not inferior to other groups regarding admission rates and avoided hospital admissions.

Going Against the Flow: Impacts of Effective Streaming on Older Adults on the Acute Floor

Abstract Background The development of a dedicated Age-related acute medical unit, with a Registered Advanced Nurse Practitioner (RANP) in Gerontology, targeting older adults with complex health states/Geriatric syndromes presenting to unscheduled care, commenced in Q4 of 2022. Methods An age attuned 4-cubical Age-Related Assessment Unit (ARAU) was created and co-located with the Acute Medical Unit (AMU). The RANP in Gerontology for ARAU operated under the guidance of the AMU consultants, providing comprehensive geriatric assessment to older medical patients presenting to unscheduled care. Results With the establishment of ARAU, the commencement of the RANP in Gerontology, and the additional focus on streaming and management of acute medical gerontological presentations through the ARAU, there has been a 63% increase in patients aged 75+ treated via the AMU in 2023 (378 patients aged 75+ -2022 vs 618 Patients aged 75+ - 2023). A key area of focus in this patient population group, Patient Experience Times (PET) in decision to admit vs discharge within a 6 hour time frame, showed marked improvement (25% increase 2022 vs 2023 in PET targets met), highlighting the impact of a dedicated age attuned assessment space and RANP in gerontology on the acute floor. Conclusion The RANP in ARAU provides advanced specialist geriatric nursing skills and knowledge to positively impact on 75+ flow and PETs while addressing the medical, psychosocial and functional needs of older adults who present to unscheduled care.

Optimising Care For Nursing Home Residents: Exploring The Potential Of An Emergency Department Avoidance Pathway

Abstract Background Nursing home residents (NHRs) often face hospital admissions through the emergency department (ED), leading to complications such as delirium, pressure ulcers, and functional decline. To mitigate these risks, ED avoidance models of care are becoming increasingly popular within healthcare systems. These models advocate for ambulatory pathways that provide access to multidisciplinary teams capable of delivering timely care for patients who do not require hospital admission. Methods A retrospective review of clinical data spanning 14 months (February 2023 to April 2024) was conducted, focusing on NHRs admitted to hospital for less than three days. Data were collected from electronic patient records, including age, sex, reason for admission, National Early Warning Score (NEWS), Manchester Triage (MT) score at admission, and length of stay in the ED. Results 325 NHRs were admitted medically during the study period. 18.7% (n=61) had inpatient stays of less than 36 hours. The most common reasons for ED presentation were lower respiratory tract infections, seizures, collapse or falls, and delirium. Of these patients, 51%(n=32) had a NEWS of ≤2, indicating low acuity, while 38% had an MT score of ≤3, suggesting lower urgency. The average patient experience time in the ED was 15.88 hours. Conclusion Approximately half of all short stay NHR admissions exhibited low acuity NEWS scores at the time of presentation, indicating the potential for an ambulatory care pathway for over 10% of all our NHR admissions. Implementing an ED avoidance pathway through our Acute Medical Unit could allow many of these patients to receive appropriate care without long periods in the ED, thereby reducing potential complications. These findings highlight opportunities to streamline care pathways and reduce unnecessary hospitalisations for NHRs. Implementing an ED avoidance service tailored to the specific needs of these patients could enhance care efficiency and improve patient outcomes.

An Audit of Time to Inpatient Bed In Patients With A Suspected Delirium

Abstract Background Our local Dementia/Delirium Combined Pathway and Care Bundle for Emergency Department (ED) and Acute Medical Assessment Unit sets a target door to ward admission in patients aged over 65 years with a suspected delirium at less than 6 hours. This audit assessed if this target is being met in patients with a suspected delirium. Methods Retrospective point prevalence audit of 240 randomly selected patients who were assessed by the Frailty Intervention Team (FIT) in the Mater Misericordiae University Hospital ED in 2022, aged ≥ 65 years with a suspected delirium (4AT ≥4) and no delirium (4AT=0). Time of presentation to ED, time of admission to ward bed, ward name and length of hospital stay were recorded. Results The median age in patient's with a 4AT ≥4 was 86 years (range 65-99). There was an equal spread across gender groups in patient's with a 4AT ≥4; 55.3% (n=52) females and 44.7% (n=42) male. The median wait time in ED for patients with a 4AT ≥4 was 25.26 hours (range 6.75-83.73) vs 21.65 hours (range 5.98-50.53) in patients with a 4AT=0. Only 19% (n=18) of patients with a 4AT ≥4 were admitted to a Specialist Geriatric Ward. The mean length of stay in patients with a 4AT ≥4 was 28.457 days vs 14.132 days in those with a 4AT=0 (p value=0.002, Mann-Whitney U test). Conclusion Older adults with a delirium spend prolonged periods of time in the ED. We are not meeting our local target of 6 hours from ED presentation to ward bed. Length of hospital stay is prolonged in patients with delirium. Our aim is to create a dedicated delirium bed on our Geriatric Specialty Ward so that we can provide delirium specific care and reduce overall length of hospital stay.

An Exploration Of Delirium Awareness Amongst Clinical Staff Working On The Acute Floor Of A Level Three Hospital

Abstract Background Delirium is an acute change in cognitive function that has an organic cause and is likely to be reversible or preventable (HSE Delirium Algorithm, 2021). The Frailty Intervention Team (FIT) based in the Emergency Department (ED) &amp; Acute Medical Assessment Unit (AMAU) comprises of Physiotherapy, Occupational Therapy and Dietetics and is supported by an Older Persons Advanced Nurse Practitioner. The 4AT delirium screen is routinely completed by FIT as part of Comprehensive Geriatric Assessment. FIT observed limited use of delirium screening in ED/AMAU therefore we proposed to explore delirium awareness amongst all clinical staff on the acute floor. Methods All clinical staff in ED/AMAU were invited to complete an anonymised paper questionnaire to explore their awareness of delirium. Basic statistical analysis of data was completed using Excel. Results Over one week twenty-four questionnaires were completed by medical, nursing, allied health and health care assistants. Six questions explored delirium awareness and a seventh question explored the willingness to engage in delirium information sessions if made available to staff locally. On assessment of delirium awareness an average score of 79.3% (range 16.7%-100%) was achieved. Participants scored strongly on potential causes of and screening for delirium. Questions relating to delirium symptoms and potential outcomes of unrecognised delirium had the least correct response rates. 100% of respondents expressed interest in attending delirium information sessions if made accessible to them within ED/AMAU. Conclusion This study identified overall satisfactory delirium awareness amongst clinical staff on the acute floor and all participants expressed interest in expanding their knowledge in this area. Compliance with use of delirium screening tools in clinical practice was not assessed and we also acknowledge the limited number of participants. Future plans include audit of the use of delirium screening tools, delivery of delirium information sessions and provision of accessible delirium resources in ED/AMAU.

Community Specialist Teams: Are We Making an Impact? Insights from General Practitioners

Abstract Background Within our catchment area, General Practitioners (GPs) are the primary source of referral to community specialist teams (CSTs) for older adults and are key stakeholders in supporting the integrated care pathway. We sought to evaluate their experience to inform service development. Methods GPs across four healthcare networks were invited to complete an online questionnaire evaluating their experience of the CSTs for older adults. Results Twenty-eight GPs responded. Of these, 85.7% (24) found the referral criteria clear, and 89.3% (25) reported ease of access to the service. However, 50% (14) were uncertain about when to refer patients to primary care alone versus the CST. A significant majority, 96.5% (27), felt the service positively impacted the health and well-being of referred patients, and 92.9% (26) were satisfied with communication regarding patient care plans and progress. Identified strengths of the service included the multidisciplinary approach to providing comprehensive, patient-centered care and effective communication with both GPs and patients. Areas for improvement included enhancing access for specialist teams to community radiology and increasing staffing levels to ensure timely assessments. Regarding the impact on unscheduled and emergency care, 71.4% (20) reported a reduced need to refer to the acute medical unit, and 35.7% (10) reported a reduced need to refer to the emergency department due to the ability to refer to CSTs. Conclusion GPs value the CST service for the quality of assessment and intervention their patients receive. Targeted areas for operational and clinical improvement include provision of diagnostics and role distinction from primary care teams. This survey also suggests CSTs are providing an alternative care pathway and point of contact for older patients in crisis, resulting in a reduction in unscheduled and emergency care utilisation. The role of the CSTs should be supported and enhanced and warrants more detailed exploration.

What matters in acute care? Values and decision making in the acute medical unit

An acute medical unit (AMU) requires a broad range of decisions to be made under time pressure, where consensus is not always easily attainable. In such circumstances, having a clear and workable framework of values is of heightened importance in order to judge what course of action is best. Within the NHS, a multi-value framework and a single-value framework have both been proposed in the last 10 years. However, it remains unclear what values currently guide the work of an AMU. Data from a 16-month ward-based ethnography in an AMU in the north of England, supported by 27 semi-structured interviews, were analysed thematically in order to characterise a framework of values in decision making. Within an AMU, people figure out what is best according to three values simultaneously: welfare, choice and effectiveness. These values operate as an irreducible triad, with implications for holism and realism in healthcare.

The First Observational Study of Acute Medical Unit in Qatar

Abstract Background Acute medical unit (AMU) is a dedicated facility to treat patients with acute medical conditions requiring a short hospital stay (&lt; 72 hours) with the support of a multidisciplinary team led by a medical consultant. We aim to present a study of the AMU model of care from Qatar to provide insight into its effects on patient care and management. Methods Retrospective data from AMU facility at Hamad General Hospital (HGH), Doha, Qatar, was collected from January 2019 to December 2020 from the electronic patient record. The data were analyzed for demographic characteristics of the patients, length of stay (LOS), readmission rate, and postdischarge follow-up. The effectiveness of the AMU system was studied closely from this data. An extensive literature search was also performed for comparative results analysis in other AMU facilities outside Qatar. Results Total admissions under the AMU facility were 8,371 from january2019 to December 2020. The 28 days readmission rate was 10.25 and 9.9% in 2019 and 2020, respectively. The average LOS was approximately 3.2 days. Around 88.7% of the patients were discharged home, 7.8% were admitted to medical wards due to longer stays, and 0.5% left against medical advice. Most of the patients admitted under AMU were 18 to 60 years old. The top primary diagnoses of admissions were minor stroke, transient ischemic attack, chest infection, urinary tract infections, and gastrointestinal and liver diseases. The most common comorbidities were hypertension, diabetes, acute kidney injury, and chronic kidney disease. A total of 2,858 patients were booked for a follow-up visit in the postdischarge clinic on discharge from the AMU for the year 2019 and 2020. The analysis of these followed up patients showed 73% of patients were discharged from clinic after first visit while the readmission from clinic was on only 1% (28 patients for year 2019 and 2020). Conclusion Attentive patient care under AMU with a designated multidisciplinary medical team led by an internal medicine consultant is the cornerstone for the success of the AMU unit. This unit has proven very helpful for the smooth disposition of patients from the emergency department with reduced LOS, readmission rate, and overall mortality.

Predicting whether patients in an acute medical unit are physiologically fit-for-discharge using machine learning: A proof-of-concept

IntroductionDelays in discharging patients from Acute Medical Units hamper patient flows throughout the hospital. The decision to discharge a patient is mainly based on the patients’ physiological condition, but may vary between physicians. An objective decision-support system based on patients’ physiological data may help minimizing unnecessary delays in discharge. The aim of this proof-of-concept study is to assess the feasibility of predicting whether patients in an Acute Medical Unit are physiologically fit-for-discharge using machine learning with commonly available hospital data. Furthermore, this study investigated how long before actual time of discharge from the Acute Medical Unit we could predict discharge fitness. Also, the predictive importance of features extracted from these data was assessed. MethodsElectronic Medical Records of patients who participated in a Randomized Controlled Trial conducted in an Acute Medical Unit were used retrospectively (N = 199). Only commonly available hospital data were used. Logistic Regression and Random Forest models were applied to predict every hour whether patients were physiologically fit-for-discharge. Nested 5-fold cross-validation with 5 repeats was used to optimize the model hyperparameters and to estimate the predictive performances. ResultsPhysiological discharge fitness was predictable with reasonable performance for Logistic Regression (mean AUROC: 0.67) and Random Forest (mean AUROC: 0.69). For an intuitively chosen classification threshold of 0.8, mean specificity was 93.3 % and sensitivity 14.1 %. Models could predict physiological discharge fitness more than 24 h earlier than actual time of discharge for most patients who were correctly predicted to be fit-for-discharge. Patient characteristics, vital signs and laboratory results were shown to be important predictors. ConclusionThis proof-of-concept study showed that it is feasible to predict with machine learning whether patients in an Acute Medical Unit are physiologically fit-for-discharge using commonly available hospital data.

Economic evaluation of the hospitalist care model in an acute medical unit: a benefit–cost analysis

ObjectiveThis study aimed to assess the economic efficiency of the acute medical unit (AMU) hospitalist care model, utilising patient outcomes (length of hospital stay, emergency department (ED)-length of hospital stay,...

Pre-Frailty and Frailty in Hospitalized Older Adults: A Comparison Study in People with and without a History of Cancer in an Acute Medical Unit.

A prospective observational study was conducted in a cohort of older adults ≥65 years (n = 329), admitted to the acute medical unit (AMU) of a tertiary hospital, to describe and compare characteristics including frailty status and clinical outcomes. Multivariable models compared older adults with and without a history of cancer to determine characteristics associated with frailty and pre-frailty. An adjusted Poisson regression model was used to compare the length of hospital stay (LOS) between the two groups. About one-fifth (22%) of the cohort had a history of cancer. The most common cancer types were prostate (n = 20), breast (n = 13), lung (n = 8) and gastrointestinal (n = 8). There was no difference in the prevalence of pre-frailty/frailty among patients with or without a history of cancer (58% vs. 57%, p > 0.05). Pre-frailty/frailty was associated with polypharmacy (OR 8.26, 95% CI: 1.74 to 39.2) and malnutrition (OR 8.91, 95% CI: 2.15 to 36.9) in patients with a history of cancer. Adjusted analysis revealed that the risk of having a longer LOS was 24% higher in older adults with a history of cancer than those without (IRR 1.24, 95% CI 1.10 to 1.41, p < 0.001). Clinicians in the AMU should be aware that older adults with a history of cancer have a higher risk of a longer LOS compared to those without.

The Impact of Real-Time Documentation of In-Hospital Medication Changes on Preventing Undocumented Discrepancies at Discharge and Improving Physician-Pharmacist Communication: A Retrospective Cohort Study and Survey.

Transitional medication safety is crucial, as miscommunication about medication changes can lead to significant risks. Unclear or incomplete documentation during care transitions can result in outdated or incorrect medication lists at discharge, potentially causing medication errors, adverse drug events, and inadequate patient education. These issues are exacerbated by extended hospital stays and multiple care events, making accurate medication recall challenging at discharge. Thus, we aimed to investigate how real-time documentation of in-hospital medication changes prevents undocumented medication changes at discharge and improves physician-pharmacist communication. We conducted a retrospective cohort study in a tertiary hospital. Two pharmacists reviewed medical records of patients admitted to the acute medical unit from April to June 2020. In-hospital medication discrepancies were determined by comparing preadmission and hospitalization medication lists and it was verified whether the physician's intent of medication changes was clarified by documentation. By a documentation rate of medication changes of 100% and <100%, respectively, fully documented (FD) and partially documented (PD) groups were defined. Any undocumented medication changes at discharge were considered a "documentation error at discharge". Pharmacists' survey was conducted to assess the impact of appropriate documentation on the pharmacists. After reviewing 400 medication records, patients were categorized into FD (61.3%) and PD (38.8%) groups. Documentation errors at discharge were significantly higher in the PD than in the FD group. Factors associated with documentation errors at discharge included belonging to the PD group, discharge from a non-hospitalist-managed ward, and having three or more intentional discrepancies. Pharmacists showed favorable attitudes towards physician's documentation. Appropriate documentation of in-hospital medication changes, facilitated by free-text communication, significantly decreased documentation errors at discharge. This analysis underlines the importance of communication between pharmacists and hospitalists in improving patient safety during transitions of care.

Improving antibiotic stewardship in an acute medical unit

Antibiotic resistance is related to the incorrect/inappropriate use of antibiotics.In 2019, there were nearly 5 million deaths associated with bacterialantimicrobial resistance across 204 countries. There has been anincrease in antibiotic prescription within secondary care by about 4.8%since the COVID-19 pandemic. Appropriate use of antibiotics reducesthe risk of antibiotic resistance and attendant morbidity and mortality.The aim was to improve compliance with trust guidelines when prescribingantibiotics as well as documentation of antibiotic indication andreview date.A retrospective study was conducted for patients admitted to AMUin October ‘22 who had been prescribed antibiotics as part of theirmanagement.
