Assessing nourishment problems at a hospital: what can we learn from them?

INTRODUCTION: Patient safety is a high priority in the Danish health care system, including that hospital patients get the proper nutrition during their stay. A Nutrition Committee at Odense University Hospital is responsible for policy regarding nourishment at the hospital. If patients experience suboptimal treatment, i.e. improper nourishment, in the Danish health care system, they have the right to file a complaint. These complaints enable the improvement potentials based on the patients' first hand experiences. Therefore, our aim was to examine the nutrition complaint pattern and to get a deeper understanding of the context surrounding nutrition problems, allowing the extraction of learning potentials. METHODS: We analysed complaints submitted to Odense University Hospital between 2018 and 2022 using the Healthcare Complaint Analysis Tool. The complaints were categorised into categories, levels of severity and overall patient harm. The complaints containing a high-severity nutrition problem were read through and thematised into aspects not defined in the Healthcare Complaint Analysis Tool. RESULTS: Between 2018 and 2022, 60 complaint cases containing 89 nutrition problems were filed to Odense University Hospital. Most (58.3%) of these were filed by the patients' relatives. The nutrition problems were mostly of low severity (56.2%), while 23.6% were severe, and 20.2% were very severe. The reading of 18 very severe nutrition complaints revealed a cascade of problems triggered by the nutrition problem in six cases. Moreover, we saw that two high-severity nutrition problems led to catastrophic harm. DISCUSSION: A low proportion of nutrition problems may express an underestimation regarding nourishment at the hospital. A patient's threshold may not be exceeded by suboptimal nutrition and therefore does not file a complaint. However, complaints contain important insights contributing to wider learning, given that improvements at the hospital so far are based on clinicians' reporting, overlooking the patient perspective.

Variation in opinions on coercion use among mental healthcare professionals: a questionnaire study.

INTRODUCTION: Even if coercive measures are widely applied in psychiatry and have numerous well-known drawbacks, there is limited known on the agreement among mental healthcare professionals' opinions on their use. In a questionnaire study using standardized scenarios, we investigated variation in staff opinions on coercion. METHODS: In a web-based survey distributed to staff at three psychiatry hospitals, respondents were asked to consider if and what coercion to use by introducing two hypothetical scenarios involving involuntary psychiatric admission and in-hospital coercion. RESULTS: One hundred thirty-two out of 601 invited staff members responded to the survey (Response Rate = 22%). There was large variation in participating staff members' opinions on how to best manage critical situations and what coercive measures were warranted. In the first scenario, 57% of respondents (n = 76) believed that the patient should be involuntarily admitted to hospital while the remaining respondents believed that the situation should be managed otherwise. Regarding the second scenario, 62% of respondents responded that some in-hospital coercion should be used. The majority of respondents believed that colleagues would behave similarly (60%) or with a tendency towards more coercion use (34%). Male gender, being nursing staff and having less coercion experience predicted being less inclined to choose involuntary hospital admission. CONCLUSION: There is a high degree of variation in coercion use. This study suggests that this variation persists despite staff members being confronted with the same standardized situations. There is a need for evidence-based further guidance to minimize coercion in critical mental healthcare situations.

Staff responses to interventions aiming to reduce mechanical restraint in adult mental health inpatient settings: a questionnaire-based survey.

PURPOSE: To explore mental health staff's responses towards interventions designed to reduce the use of mechanical restraint (MR) in adult mental health inpatient settings. METHODS: We conducted a cross-sectional, questionnaire-based survey. The questionnaire, made available online via REDCap, presented 20 interventions designed to reduce MR use. Participants were asked to rate and rank the interventions based on their viewpoints regarding the relevance and importance of each intervention. RESULTS: A total of 128 mental health staff members from general and forensic mental health inpatient units across the Mental Health Services in the Region of Southern Denmark completed the questionnaire (response rate = 21.3%). A total of 90.8% of the ratings scored either 'agree' (45.2%) or 'strongly agree' (45.6%) concerning the relevance of the interventions in reducing MR use. Overall and in the divided analysis, interventions labelled as 'building relationship' and 'patient-related knowledge' claimed high scores in the staff's rankings of the interventions' importance concerning implementation. Conversely, interventions like 'carers' and 'standardised assessments' received low scores. CONCLUSIONS: The staff generally considered that the interventions were relevant. Importance rankings were consistent across the divisions chosen, with a range of variance and dispersion being recorded among certain groups.

Using complaints from obstetric care for improving women's birth experiences - a cross sectional study.

INTRODUCTION: Staff shortages and quality in obstetric care is a concern in most healthcare systems and a hot topic in the public debate that has centred on complaints about deficient care. However there has been a lack of empirical data to back the debate. The aim of this study was to analyse and describe complaints in obstetric care. Further, to compare the obstetric complaint pattern to complaints from women about other hospital services. MATERIALS AND METHODS: We used the Healthcare Complaints Analysis Tool to code, analyse and extract contents of obstetric complaint cases in a region of Denmark between 2016 and 2021. We compared the obstetric complaint pattern to all other hospital complaint cases in the same period regarding female patients at a large University Hospital in a cross-sectional study. RESULTS: Complaints regarding obstetric care differed from women's complaints regarding other healthcare services. Women from obstetric care raised more problems per complaint, and tended to complain more about relational issues indicated by odds for complaints about staff shortage four times higher in the obstetric care group. Women from obstetric care had a lower proportion of compensation claims. CONCLUSION: Systematic complaint analysis acknowledged women's experience in obstetric care and may point to areas that potentially need further attention. Complaints from obstetric care show that women experience deficiencies related to relational problems like recognition and individualized support compared to complaints from women receiving other hospital healthcare services.

Utilisation and time to performance of diagnostic imaging in patients admitted to Danish emergency departments: a nationwide register-based study from 2007 to 2017.

OBJECTIVES: To describe the development of diagnostic imaging utilisation in Denmark from 2007 to 2017, coinciding with a major national reform of the emergency healthcare system. DESIGN: Nationwide descriptive register-based study. SETTING: All public hospitals in Denmark. PARTICIPANTS: All unplanned hospital contacts ≥18 years old at somatic hospitals in Denmark from 1 January 2007 to 31 December 2017. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was the probability of having CT, X-ray, MRI or ultrasound performed during hospitalisation in 2017 compared with 2007. The secondary outcome measure was receiving diagnostic imaging within 4 hours of hospitalisation. RESULTS: The probability of having a radiological examination during unplanned hospital admission increased from 2007 to 2017 (CT: 3.5%-10.3%; MRI: 0.2%-0.8%; ultrasound: 2.3%-4.5%; X-ray: 23.8%-26.8%). For CT scan, the adjusted OR was 3.09 (95% CI: 2.73, 3.51); for MRI, the adjusted OR was 3.39 (95% CI: 1.87, 6.12) and for ultrasound, the adjusted OR was 1.93 (95% CI: 1.56, 2.38). The likelihood of having the examination within the first 4 hours in the hospital increased from 2007 to 2017. For X-ray, the adjusted OR was 1.39 (95% CI: 1.07, 1.56); for CT scan, the adjusted OR was 1.35 (95% CI: 1.16, 1.59); for MRI, the adjusted OR was 1.34 (95% CI: 1.09, 1.66) and for ultrasound, the adjusted OR was 1.38 (95% CI: 1.16, 1.64). CONCLUSION: This nationwide study describes the development of diagnostic imaging utilisation in Denmark from 2007 to 2017. The probability of receiving radiological examinations during unplanned hospitalisation increased over this period, and the time from hospital contact to performance decreased. This supports the notion that enhancement in radiological equipment will also lead to more frequent and faster utilisation.

Centralization of emergency hospital care is not associated with increased in-hospital mortality; a population-based cohort study.

BACKGROUND: We describe changes in the distance travelled, the utilization of emergency services, and the inhospital mortality before and after the centralization of hospital emergency services in Denmark. METHODS: All unplanned non-psychiatric hospital contacts from adults (aged ≥18 years) in 2008 and 2016 are included. Analyses are age-standardized and conducted at a municipality level. The municipalities are divided into groups according to the presence of emergency hospital services. RESULTS: Municipalities where hospitals with emergency services have been closed differed by having the most significant increase in distance travelled from 2008 to 2016. All groups experienced a reduction in overall in-hospital mortality. The reduction in mortality was not present for acute myocardial infarct contacts from municipalities where hospitals with emergency services have been closed. CONCLUSION: Our data do not suggest that hospital closures, and thereby increased travel distance, have contributed significantly as a barrier to emergency-care access and changes to in-hospital mortality.

The COVID-19 pandemic has not affected the mortality for patients admitted with pneumonia in Denmark.

During the COVID-19 pandemic, several hospital systems observed a reduction in patients with respiratory complaints. Using the Danish national registers, we conducted an observational study on disease severity and 30-day all-cause mortality for acutely admitted pneumonia patients before (3/19-3/20) and during (3/20-2/21) the pandemic. We calculated mortality rate ratios and Cox regression analyses. We identified 54,405 patients and during the pandemic, patients were older, more likely to be male, had more co-morbidity and a lower albumin on admission. Crude mortality was higher during the pandemic (8.4 vs. 6.9%). Adjusted hazard ratio for 30-day all-cause mortality was 1.07 (95%CI 1.01-1.14). We showed a small but significant, increase in mortality risk for patients admitted to hospital during the COVID-19 pandemic in Denmark.

Does systematic analysis of patient complaints and compensation cases at hospitals provide useful information to guide quality improvement? Experience from Denmark.

BACKGROUND: Patient complaints and compensation cases are analysed individually and do not allow for organisational learning. Systematic information on complaint patterns needs evidence-based measures. The Healthcare Complaints Analysis Tool (HCAT) can systematically code and analyse complaints and compensation claims, but whether this information is useful for quality improvement is underexplored. We aim to explore if and how HCAT information is perceived useful to inform healthcare quality gaps. METHODS: To explore the HCAT's usefulness for quality improvement purposes, we used an iterative process. We accessed all complaints relating to a large university hospital. Trained HCAT raters systematically coded all cases, using the Danish version of HCAT. INTERVENTION: The intervention had four phases: (1) coding of cases, (2) education, (3) selection of HCAT analyses for dissemination, (4) 'dashboard' development and delivery of targeted HCAT reports. To study the interventions and phases, we used quantitative and qualitative approaches. The coding patterns were descriptively displayed on department and hospital level. The educational programme was monitored using passing rates, coding reliability checks and rater feedback. Online interviews recorded dissemination feedback. We used a phenomenological approach with thematised quotations from the interviews to analyse the usefulness of the information from cases coded. RESULTS: We coded 5217 complaint cases (11 056 complaint points). The average case coding time was 8.5 min (95% CI 8.2 to 8.7). All four raters passed the online test with >80% correct answers. Using rater feedback, we handled 25 cases of doubt. None affected the HCAT structure or categories. Interviews verified the usefulness of analyses after expert group dissemination. Three themes were important: 'overview of complaints', 'learning from complaints' and 'listening to the patients'. Stakeholders perceived the 'dashboard' development as highly relevant. CONCLUSION: Through the development process with several adjustments, stakeholders found the systematic approach useful for quality improvement. The hospital management evaluated the approach as promising and decided to test the approach in clinical practice.

Mortality before and after reconfiguration of the Danish hospital-based emergency healthcare system: a nationwide interrupted time series analysis.

OBJECTIVES: The study aimed to investigate how the 'natural experiment' of reconfiguring the emergency healthcare system in Denmark affected in-hospital and 30-day mortality on a national level. The reconfiguration included the centralisation of hospitals and the establishment of emergency departments with specialists present around the clock. DESIGN: Hospital-based cohort study. SETTING: All public hospitals in Denmark. PARTICIPANTS: Patients with an unplanned contact from 1 January 2007 until 31 December 2016. INTERVENTIONS: Stepped-wedge reconfiguration of the Danish emergency healthcare system. MAIN OUTCOME MEASURES: We determined the adjusted ORs for in-hospital mortality and HRs for 30-day mortality using logistic and Cox regression analysis adjusted for sex, age, Charlson Comorbidity Index, income, education, mandatory referral and the changes in the out of hours system in the Capital Region. The main outcomes were stratified by the time of arrival. We performed subgroup analyses on selected diagnoses: myocardial infarction, stroke, pneumonia, aortic aneurysm, bowel perforation, hip fracture and major trauma. RESULTS: We included 11 367 655 unplanned hospital contacts. The adjusted OR for overall in-hospital mortality after reconfiguration of the emergency healthcare system was 0.998 (95% CI 0.968 to 1.010; p=0.285), and the adjusted OR for 30-day mortality was 1.004 (95% CI 1.000 to 1.008; p=0.045)). Subgroup analyses showed some possible benefits of the reconfiguration such as a reduction in-hospital and 30-day mortality for myocardial infarction, stroke, aortic aneurysm and major trauma. CONCLUSIONS: The Danish emergency care reconfiguration programme was not associated with an improvement in overall in-hospital mortality trends and was associated with a slight slowing of prior improvements in 30-day mortality trends.

Readmission trends before and after a national reconfiguration of emergency departments in Denmark.

OBJECTIVE: In order to achieve better and more efficient emergency health care, the Danish public hospital system has been reconfigured, with hospital emergency care being centralised into extensive and specialised emergency departments. This article examines how this reconfiguration has affected patient readmission rates. METHODS: We included all unplanned hospital admissions (aged ≥18 years) at public, non-psychiatric hospitals in four geographical regions in Denmark between 1 January 2007 and 24 December 2017. Using an interrupted time-series design, we examined trend changes in the readmission rates. In addition to analysing the overall effect, analyses stratified according to admission time of day and weekdays/weekends were conducted. The analyses were adjusted for patient characteristics and other system changes. RESULTS: The seven-day readmission rate increased from 2.6% in 2007 to 3.8% in 2017, and the 30-day rate increased from 8.1% to 11.5%. However, the rates were less than what they would have been had the reconfiguration not been introduced. The reconfiguration reduced the seven-day readmission rate by 1.4% annually (hazard ratio [CI 95%] 0.986 [0.981-0.991]) and the 30-day rate by 1% annually (hazard ratio [CI 95%] 0.99 [0.987-0.993]). CONCLUSIONS: Reconfiguration reduced the rate of increase in readmissions, but nevertheless readmissions still increased across the study period. It seems hospitals and policymakers will need to identify further ways to reduce patient loads.

Methodological approaches for medication error analyses in patient safety and pharmacovigilance reporting systems: a scoping review protocol.

INTRODUCTION: Medication errors (MEs) are associated with patient harm and high economic costs. Healthcare authorities and pharmacovigilance organisations in many countries routinely collect data on MEs via reporting systems to improve patient safety and for learning purposes. Different approaches have been developed and used for the ME analysis, but an overview of the scope of available methods currently is lacking. This scoping review aimed to identify, explore and map available literature on methods used to analyse MEs in reporting systems. METHODS AND ANALYSES: This protocol describes a scoping review, based on the Joanna Briggs Institute methodological framework. A systematic search will be performed in MEDLINE (Ovid), Embase (Ovid), Cinahl (EBSCOhost), Cochrane Central, Google Scholar, websites of the major pharmacovigilance centres and national healthcare safety agencies, and citation search in Scopus in August 2022. All retrieved records are to be independently screened by two researchers on title, abstract and full text, involving a third researcher in case of disagreement. Data will be extracted and presented in descriptive and tabular form. The extraction will be based on information about methods of ME analyses, type of reporting system and information on MEs (medication name, ATC codes, ME type, medication-event categories and harm categories). ETHICS AND DISSEMINATION: Ethical approval is not required. The results will be disseminated via publication in peer-reviewed journals, scientific networks and relevant conferences.

Compensation Claims in Danish Emergency Care: Identifying Hot Spots and Blind Spots in the Quality of Care.

BACKGROUND: The Healthcare Complaints Analysis Tool (HCAT) offers a validated way of systematically extracting content from patient complaints for further analysis of complaint hot spots with harm or near misses, and blind spots with, for example, systemic problems or quality problems arising during discharge. This study analyzed a Danish national sample of compensations claims about emergency care using the HCAT. METHODS: Through use of the HCAT, compensation claims about Danish emergency care from 2013 to 2017 (N = 712) were coded and then grouped to identify and highlight hot spot problem areas (harm and near misses) and blind spot problem areas (admission/discharge, systemic problems, errors of omission). Two assessors coded the compensation claims by entering data into a database. RESULTS: The HCAT analyses of the sample resulted in coding of 1,305 problems. Most problems concerned quality and safety issues at the examination/diagnosis stage of care (63.9%). In 91.2% of the cases, the level of harm was moderate or major. Harm hot spots most often involved diagnostic errors (189 problems). Eighty-nine problems related to errors of omission, all causing moderate or major harm. For systemic blind spots, patient harm significantly increased in cases of multiple problem types in the compensation claim (odds ratio = 1.6, 95% confidence interval = 1.3-2.0). CONCLUSION: Systematic coding and analytic approach to the HCAT can highlight potential quality problems in emergency care and point to areas for further consideration. From the perspective of future health care harm prevention, there seems to be a strong incentive for further analysis of the amount, nature, and prevention of diagnostic errors in emergency care.

Nationwide study on trends in unplanned hospital attendance and deaths during the 7 weeks after the onset of the COVID-19 pandemic in Denmark.

BACKGROUND: The impact of a pandemic on unplanned hospital attendance has not been extensively examined. The aim of this study is to report the nationwide consequences of the COVID-19 pandemic on unplanned hospital attendances in Denmark for 7 weeks after a 'shelter at home' order was issued. METHODS: We merged data from national registries (Civil Registration System and Patient Registry) to conduct a study of unplanned (excluding outpatient visits and elective surgery) hospital-based healthcare and mortality of all Danes. Using data for 7 weeks after the 'shelter at home' order, the incidence rate of unplanned hospital attendances per week in 2020 was compared with corresponding weeks in 2017-2019. The main outcome was hospital attendances per week as incidence rate ratios. Secondary outcomes were general population mortality and risk of death in-hospital, reported as weekly mortality rate ratios (MRRs). RESULTS: From 2 438 286 attendances in the study period, overall unplanned attendances decreased by up to 21%; attendances excluding COVID-19 were reduced by 31%; non-psychiatric by 31% and psychiatric by 30%. Out of the five most common diagnoses expected to remain stable, only schizophrenia and myocardial infarction remained stable, while chronic obstructive pulmonary disease exacerbation, hip fracture and urinary tract infection fell significantly. The nationwide general population MRR rose in six of the recorded weeks, while MRR excluding patients who were COVID-19 positive only increased in two. CONCLUSION: The COVID-19 pandemic and a governmental national 'shelter at home' order was associated with a marked reduction in unplanned hospital attendances with an increase in MRR for the general population in two of 7 weeks, despite exclusion of patients with COVID-19. The findings should be taken into consideration when planning for public information campaigns.

Quantification of Complaint and Compensation Cases by Introducing a Danish Translated and Cross-Cultural Adapted Edition of the Healthcare Complaints Analysis Tool.

PURPOSE: The study aimed to translate and cross-culturally adapt the English version of the HCAT to produce a Danish HCAT version and to test the Danish version's reliability. METHODS: We used best-practice guidelines for linguistic translations and cultural adaptations. For cross-cultural adaptation, we conducted forward and back translation followed by expert committee review. Subsequently, two researchers assessed 140 complaint cases to test intra- and inter-rater reliability of the Danish HCAT version. We used descriptive statistics for distributions and tested for differences between English and Danish editions Intra- and inter-rater reliability used Gwet's AC1 statistics, applying quadratic weights to assign more weight to large discrepancies. RESULTS: The back translations showed both semantic and conceptual differences, and the expert committee thus discussed the meaning of the wording in the HCAT guide and coding form to ensure that the Danish version would be conceptually similar to the English version but also culturally appropriate for Danish settings. There was discussion about how to use the coding form to graduate problem severity, and this led to some altered wording. Pilot testing revealed the need for two new categories of "hospital-acquired infection" and "involvement of patients' relatives". The problem categories of the HCAT-DK showed "substantial" intra- and inter-rater reliability (0.79, and 0.79 to 0.85). In addition, there was a "substantial" agreement (0.70 to 0.73) between the original HCAT and the HCAT-DK version. CONCLUSION: The study translated and cross-culturally adapted the English HCAT version to produce a Danish HCAT version. Cultural and conceptual differences led to adjustments and to addition of two extra items in the HCAT-DK. The Danish version showed "substantial" intra- and inter-rater reliability and is considered suitable for coding complaint and compensation cases in Danish health care.

Mind the gap - Evaluation of the promotion initiatives for implementation of the GLA:D® back clinician courses.

BACKGROUND: Translation of research into practice is a methodological challenge. The GLA:D® Back program was initiated to implement evidence-based care for people with low back pain inspired by GLA:D® (Good Life with osteoArthritis in Denmark) that has succeeded in implementing evidence-based care for knee and hip osteoarthritis. This study evaluates the spread and reach of promotion initiatives for GLA:D® Back clinician courses, and the adoption of the GLA:D® Back intervention in clinical practice. METHODS: Pre-defined success criteria addressed; i) spread; achievement of intended promotion activities (e.g. social media), ii) reach; recruitment of clinicians with certain profiles (e.g. gender balance). Adoption was defined as patient enrollment in the GLA:D® Back registry by course participants. Univariate and multivariate logistic regression was used to investigate associations between adoption and clinician characteristics. RESULTS: Most clinicians signed up based on information from colleagues (22%). Pre-defined goals for reach, except one, was obtained. 23% (140) of clinicians initiated the GLA:D® Back program in clinical practice within <90 days of course participation; mainly physiotherapists (p < 0.001). The odds ratio for starting GLA:D® Back patient care in a chiropractic setting was 7.4 [2.5; 21.4], indicating that physiotherapists employed by chiropractors mostly handled the intervention. CONCLUSION: Future promotion strategies should recognize the influence of colleagues and professional networks. Converting clinician courses into patient care was mostly adopted physiotherapists. Although, evaluation processes were less useful in this study, future evaluation of health care processes has potential to inform the implementation of new models in future studies.

Consecutive cycles of accreditation and quality of in-hospital care: a Danish population-based study.

BACKGROUND: Little is known about whether repeated cycles of hospital accreditation are a robust method to improve quality of care continuously. OBJECTIVE: We aimed to examine the association between compliance with consecutive cycles of accreditation and quality of in-hospital care. METHODS: We conducted a Danish nationwide population-based study including patients aged 18 years treated for acute stroke, chronic obstructive pulmonary disease, diabetes, heart failure or hip fracture at public, non-psychiatric hospitals. From 2012 to 2015, two cycles of national hospital accreditation were completed, resulting in 12 high and 14 low compliant hospitals (Low = partially accredited in both cycles). Our outcome measure was quality of in-hospital care measured by 39 process performance measures (PPMs), reflecting recommendations from the national clinical guidelines by adherence to (i) individual PPMs and (ii) the full bundle of PPMs (all-or-none). We computed adjusted odds ratios (ORs) using logistic regression based on robust standard error estimation for cluster sampling of data at hospital level. RESULTS: In total, 78 387 patient pathways covering 508 816 processes were included, of which 47% had been delivered at high compliant hospitals and 53% at low compliant hospitals, respectively. Compliance with consecutive cycles was not associated with improved quality of in-hospital care (individual: OR = 0.92, 95% confidence interval (CI): 0.77-1.10; All-or-none: OR = 0.87, 95% CI: 0.66-1.15). However, in the second cycle alone, patients treated at partially accredited hospitals had a lower adherence than patients treated at fully accredited hospitals (Individual: OR = 0.84, 95% CI: 0.71-0.99; All-or-none: OR = 0.78, 95% CI: 0.59-1.03). The association was particularly strong among patients treated at partially accredited hospitals required to submit additional documentation. CONCLUSION: Compliance with consecutive cycles of hospital accreditation in Denmark was not associated with improved quality of in-hospital care. However, compliance with the second cycle alone was associated with improved quality of in-hospital care.

Intended and unintended changes in length of stay following reconfiguration of emergency care departments.

BACKGROUND: The Danish health-care system has witnessed noticeable changes in the acute hospital care organization. The reconfiguration includes closing hospitals, centralizing acute care functions and investing in new buildings and equipment. OBJECTIVE: To examine the impact on the length of stay (LOS) and the proportion of overnight stays for hospitalized acute care patients. METHODS: This nationwide interrupted time series examined trend changes in LOS and overnight stay. Admissions were stratified based on admission time (weekdays/weekends and time of day), age and the level of co-morbidity. RESULTS: In 2007-2016, the global average LOS declined 2.9% per year (adjusted time ratio [CI (confidence interval) 95%] 0.971 [0.970-0.971]). The reconfiguration was overall not associated with change in trend of LOS (time ratio [CI 95%] 1.001 [1.000-1.002]). When admissions were stratified for either weekdays or weekends, the reconfiguration was associated with reduction of the underlying downward trend for weekdays (time ratio [CI 95%] 1.004 [1.003-1.005]) and increased downward trend for weekend admissions (time ratio [CI 95%] 0.996 [0.094-0.098]). Admissions at night were associated with a 0.7% trend change in LOS (time ratio [CI 95%] 0.993 [0.991-0.996]). The reconfiguration was not associated with trend changes for overnight stays. CONCLUSION: The nationwide reconfiguration of acute hospital care was overall not associated with change in trend for the registered LOS and no change in trend for overnight stays. However, the results varied according to hospitalization time, where admissions during weekends and nights after the reconfiguration were associated with shortened LOS.
