Associations of Government-issued ICU Admission Criteria with Clinical Practices, Outcomes, and ICU Bed Occupancy

Intensive care unit admission criteria: a scoping review

Background

Effectively identifying deteriorated patients is vital to the development and validation of automated systems designed to predict clinical deterioration. Existing outcome measures used for this purpose have significant limitations. Published criteria for admission to high acuity inpatient areas may represent markers of patient deterioration and could inform the development of alternate outcome measures.

Objectives

In this scoping review, we aimed to characterise published criteria for admission of adult inpatients to high acuity inpatient areas including intensive care units. A secondary aim was to identify variables that are extractable from electronic health records (EHRs).

Data sources

Electronic databases PubMed and ProQuest EBook Central were searched to identify papers published from 1999 to date of search. We included publications which described prescriptive criteria for admission of adult inpatients to a clinical area with a higher level of care than a general hospital ward.

Charting methods

Data was extracted from each publication using a standardised data-charting form. Admission criteria characteristics were summarised and cross-tabulated for each criterion by population group.

Results

Five domains were identified: diagnosis-based criteria, clinical parameter criteria, organ-support criteria, organ-monitoring criteria and patient baseline criteria. Six clinical parameter-based criteria and five needs-based criteria were frequently proposed and represent variables extractable from EHRs. Thresholds for objective clinical parameter criteria varied across publications, and by disease subgroup, and universal cut-offs for criteria could not be elucidated.

Conclusions

This study identified multiple criteria which may represent markers of deterioration. Many of the criteria are extractable from the EHR, making them potential candidates for future automated systems. Variability in admission criteria and associated thresholds across the literature suggests clinical deterioration is a heterogeneous phenomenon which may resist being defined as a single entity via a consensus-driven process.

Impact of the health policy for interdisciplinary collaborative rehabilitation practices in intensive care units: A difference-in-differences analysis in Japan

BACKGROUND

Early rehabilitation in intensive care units (ICUs) may be beneficial but is not routinely performed for adults with critical illness. In April 2018, the Japanese government introduced a health policy to provide financial incentives to hospitals that met the requirements of interdisciplinary collaboration and had teams specialized in ICU rehabilitation practices.

OBJECTIVES

The present study aimed to investigate whether the health policy is associated with improved clinical practices of ICU rehabilitation.

METHODS

Using a nationwide administrative inpatient database and hospital statistics data from Japan, we identified hospitals that admitted adult patients to the ICU within two days of hospital admission from April 2016 to March 2019. Using hospital-level propensity score matching, we created matched cohorts of 101,203 patients from 108 intervention hospitals that introduced the health policy, and 106,703 patients from 108 control hospitals that did not. We then conducted patient-level difference-in-differences analyses to examine changes in the percentage of patients from the intervention and control hospitals, who underwent early ICU rehabilitation within two days of ICU admission before and after the implementation of the health policy.

RESULTS

In the intervention group, patients undergoing early ICU rehabilitation increased from 10% and 36% after the policy implementation. In the control group, it increased from 11% to 13%. The difference-in-difference in the percentage of patients who underwent early ICU rehabilitation between the two groups was 24% (95% confidence interval, 19%-29%).

CONCLUSIONS

Early ICU rehabilitation can be facilitated by financial incentives for hospitals that engage in interdisciplinary collaboration with specialist teams.

IMPLICATIONS FOR CLINICAL PRACTICE

Our Findings are relevant for hospital administrators, professional organizations, and policymakers in other nations considering strategies to support the additional deployment burdens of early ICU rehabilitation. Future studies need to explore the long-term effects and sustainability of the observed improvements in ICU rehabilitation practices.

Effectiveness of medical fee revisions for psychotropic polypharmacy in patients with mood disorders in Japan: An interrupted time-series analysis using a nationwide inpatient database

BACKGROUND

This study aimed to evaluate the effects of medical fee revisions aimed to reduce psychotropic polypharmacy in Japan on the proportion of psychotropic polypharmacy in discharge prescriptions for patients with major depressive disorder (MDD) or bipolar disorder (BD) using a nationwide inpatient database.

METHODS

In this retrospective cohort study, we used the Diagnosis Procedure Combination database to identify patients with MDD or BD discharged between April 2012 and March 2021. We targeted medical fee revisions in October 2014, April 2016, and April 2018. The major outcome was the monthly proportion of psychotropic polypharmacy in prescription at discharge using the criteria following the April 2018 revision (antidepressants ≥3, antipsychotics ≥3, anxiolytics ≥3, hypnotics ≥3, or sum of anxiolytics and hypnotics ≥4). We performed interrupted time series analyses to evaluate the changes in level and trend between pre- and post-revisions.

RESULTS

We identified 63,289 and 33,780 patients with MDD and BD respectively in the entire study period. In both the patient groups, there were significant decreases in the proportion of psychotropic polypharmacy at revision in October 2014, and no significant trend and level change at revision were observed in April 2016 and April 2018, with a few exceptions.

CONCLUSIONS

The medical fee revisions aimed to reduce psychotropic polypharmacy in Japan might have had a limited impact on discharge prescriptions for patients with MDD and BD.

Experimental Implementation of NSER Mobile App for Efficient Real-Time Sharing of Prehospital Patient Information With Emergency Departments: Interrupted Time-Series Analysis

Background

With the aging society, the number of emergency transportations has been growing. Although it is important that a patient be immediately transported to an appropriate hospital for proper management, accurate diagnosis in the prehospital setting is challenging. However, at present, patient information is mainly communicated by telephone, which has a potential risk of communication errors such as mishearing. Sharing correct and detailed prehospital information with emergency departments (EDs) should facilitate optimal patient care and resource use. Therefore, the implementation of an app that provides on-site, real-time information to emergency physicians could be useful for early preparation, intervention, and effective use of medical and human resources.

Objective

In this paper, we aimed to examine whether the implementation of a mobile app for emergency medical service (EMS) would improve patient outcomes and reduce transportation time as well as communication time by phone (ie, phone-communication time).

Methods

We performed an interrupted time-series analysis (ITSA) on the data from a tertiary care hospital in Japan from July 2021 to October 2021 (8 weeks before and 8 weeks after the implementation period). We included all patients transported by EMS. Using the mobile app, EMS can send information on patient demographics, vital signs, medications, and photos of the scene to the ED. The outcome measure was inpatient mortality and transportation time, as well as phone-communication time, which was the time for EMS to negotiate with ED staffs for transport requests.

Results

During the study period, 1966 emergency transportations were made (n=1033, 53% patients during the preimplementation period and n=933, 47% patients after the implementation period). The ITSA did not reveal a significant decrease in patient mortality and transportation time before and after the implementation. However, the ITSA revealed a significant decrease in mean phone-communication time between pre- and postimplementation periods (from 216 to 171 seconds; −45 seconds; 95% CI −71 to −18 seconds). From the pre- to postimplementation period, the mean transportation time from EMS request to ED arrival decreased by 0.29 minutes (from 36.1 minutes to 35.9 minutes; 95% CI −2.20 to 1.60 minutes), without change in time trends. We also introduced cases where the app allowed EMS to share accurate and detailed prehospital information with the emergency department, resulting in timely intervention and reducing the burden on the ED.

Conclusions

The implementation of a mobile app for EMS was associated with reduced phone-communication time by 45 seconds (22%) without increasing mortality or overall transportation time despite the implementation of new methods in the real clinical setting. In addition, real-time patient information sharing, such as the transfer of monitor images and photos of the accident site, could facilitate optimal patient care and resource use.
