The Alice Springs Hospital Readmission Prevention Project (ASHRAPP): a randomised control trial

Indigenous Australians critically ill with sepsis: Characteristics, outcomes, and areas for improvement

BACKGROUND

Aboriginal and Torres Strait Islander Australians have amongst the highest incidence of sepsis globally.

OBJECTIVE

The objective of this study was to describe the characteristics, short- and long-term outcomes of non-Indigenous, Aboriginal Australian and Torres Strait Islander Australians admitted with sepsis to an intensive care unit (ICU) to inform healthcare outcome improvement.

METHODS

A retrospective cohort study of 500 consecutive sepsis admissions to the Cairns Hospital ICU compared clinical characteristics, short-term (before ICU discharge) and long-term (2000 days posthospital discharge) outcomes. Cohort stratification was done by voluntary disclosure of Indigenous status.

RESULTS

Of the 442 individual admissions, 145 (33%) identified as Indigenous Australian. Indigenous and non-Indigenous Australians had similar admission Acute Physiology and Chronic Health Evaluation-3 scores (median [interquartile range]: 70 [52-87] vs. 69 [53-87], P = 0.87), but Indigenous patients were younger (53 [43-60] vs. 62 [52-73] years, P < 0.001) and were more likely to have chronic comorbidities such as type 2 diabetes (58% vs. 23%, P < 0.001), cardiovascular disease (40% vs 28%, P = 0.01), and renal disease (39% vs. 10%, P < 0.001). They also had more hazardous healthcare behaviours such as smoking (61% vs. 45%, P = 0.002) and excess alcohol consumption (40% vs. 18%, P < 0.001). Despite this, the case-fatality rate of Indigenous and non-Indigenous Australians before ICU discharge (13% vs. 12%, P = 0.75) and 2000 days post hospital discharge (25 % vs. 28 %, P = 0.40) was similar. Crucially, however, Indigenous Australians died younger both in the ICU (median [interquartile range] 54 (50-60) vs. 70 [61-76], P < 0.0001) and 2000 days post hospital discharge (58 [53-63] vs. 70 [63-77] years, P < 0.0001).

CONCLUSIONS

Although Indigenous Australians critically ill with sepsis have similar short and long-term mortality rates, they present to hospital, die in-hospital, and die post-discharge significantly younger. Unique cohort characteristics may explain these outcomes, and assist clinicians, researchers and policy-makers in targeting interventions to these characteristics to best reduce the burden of sepsis in this cohort and improve their healthcare outcomes.

Cholecystectomy in the red centre: a review of the surgical outcomes in Central Australia in a five-year period

BACKGROUND

Despite the high rates of cholecystectomy in Australia, there is minimal literature regarding the outcomes of cholecystectomy in rural Central Australia within the Northern Territory. This study aims to better characterize the outcomes for patients undergoing cholecystectomy in Central Australia and review clinical and patient characteristics, which may affect outcomes.

METHOD

A retrospective case-control study was performed using data obtained from medical records for all patients undergoing cholecystectomy at Alice Springs Hospital in the Northern Territory from January 2018 until December 2022. Patient characteristics were gathered, and key outcomes examined included: inpatient mortality and 30-day mortality, bile duct injury, bile leak, return to theatre, conversion to open, duration of procedure, length of stay, and up-transfer to a tertiary referral centre.

RESULTS

A total of 466 patients were included in this study. Majority of the patients were female and there was a large portion of Indigenous Australians (56%). There were no inpatient mortalities, or 30-day mortalities recorded. There were two bile leaks and/or bile duct injuries (0.4%) and two unplanned returned to theatres (0.4%). Indigenous Australians were more likely to require an emergency operation and had a longer median length of stay (P < 0.001).

CONCLUSION

Cholecystectomy can be performed safely and to a high standard in Central Australia. Surgeons in Central Australia must appreciate the nuances in the management of patients who come from a significantly different socioeconomic background, with complex medical conditions when compared to metropolitan centres.

Targeted care navigation to reduce hospital readmissions in 'at-risk' patients

BACKGROUND

Care navigation is commonly used to reduce preventable hospitalisation. The use of Electronic Health Record-derived algorithms may enable better targeting of this intervention for greater impact.

AIMS

To evaluate if community-based Targeted Care Navigation, supported by an Electronic Health Record-derived readmission risk algorithm, is associated with reduced rehospitalisation.

METHODS

A propensity score matching cohort (5 comparison to 1 intervention cohort ratio) study was conducted in an 850-bed Victorian public metropolitan health service, Australia, from May to November 2017. Admitted acute care patients with a non-surgical condition, identified as at-risk of hospital readmission using an Electronic Health Record-derived readmission risk algorithm provide by the state health department, were eligible. Targeted Care Navigation involved telephone follow-up support provided for 30 days post-discharge by a registered nurse. The hazard ratio for hospital readmission was calculated at 30, 60 and 90 days post-discharge using multivariable Cox Proportional Hazards regression.

RESULTS

Sixty-five recipients received care navigation and were matched to 262 people who did not receive care navigation. Excellent matching was achieved with standardised differences between groups being <0.1 for all 11 variables included in the propensity score, including the readmission risk score. The Targeted Care Navigation group had a significantly reduced hazard of readmission at 30 days (hazard ratio 0.34; 95% confidence interval: 0.12, 0.94) compared with the comparison group. The effect size was reduced at 60 and 90 days post-discharge.

CONCLUSION

We provide preliminary evidence that Targeted Care Navigation supported by an Electronic Health Record-derived readmission risk algorithm may reduce 30-day hospital readmissions.

Medication review in hospitalised patients to reduce morbidity and mortality

BACKGROUND

A medication review can be defined as a structured evaluation of a patient's medication conducted by healthcare professionals with the aim of optimising medication use and improving health outcomes. Optimising medication therapy though medication reviews may benefit hospitalised patients.

OBJECTIVES

We examined the effects of medication review interventions in hospitalised adult patients compared to standard care or to other types of medication reviews on all-cause mortality, hospital readmissions, emergency department contacts and health-related quality of life.

SEARCH METHODS

In this Cochrane Review update, we searched for new published and unpublished trials using the following electronic databases from 1 January 2014 to 17 January 2022 without language restrictions: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP). To identify additional trials, we searched the reference lists of included trials and other publications by lead trial authors, and contacted experts.

SELECTION CRITERIA

We included randomised trials of medication reviews delivered by healthcare professionals for hospitalised adult patients. We excluded trials including outpatients and paediatric patients.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials, extracted data and assessed risk of bias. We contacted trial authors for data clarification and relevant unpublished data. We calculated risk ratios (RRs) for dichotomous data and mean differences (MDs) or standardised mean differences (SMDs) for continuous data (with 95% confidence intervals (CIs)). We used the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach to assess the overall certainty of the evidence.

MAIN RESULTS

In this updated review, we included a total of 25 trials (15,076 participants), of which 15 were new trials (11,501 participants). Follow-up ranged from 1 to 20 months. We found that medication reviews in hospitalised adults may have little to no effect on mortality (RR 0.96, 95% CI 0.87 to 1.05; 18 trials, 10,108 participants; low-certainty evidence); likely reduce hospital readmissions (RR 0.93, 95% CI 0.89 to 0.98; 17 trials, 9561 participants; moderate-certainty evidence); may reduce emergency department contacts (RR 0.84, 95% CI 0.68 to 1.03; 8 trials, 3527 participants; low-certainty evidence) and have very uncertain effects on health-related quality of life (SMD 0.10, 95% CI -0.10 to 0.30; 4 trials, 392 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

Medication reviews in hospitalised adult patients likely reduce hospital readmissions and may reduce emergency department contacts. The evidence suggests that mediation reviews may have little to no effect on mortality, while the effect on health-related quality of life is very uncertain. Almost all trials included elderly polypharmacy patients, which limits the generalisability of the results beyond this population.

Discharge planning from hospital

BACKGROUND

Discharge planning is a routine feature of health systems in many countries that aims to reduce delayed discharge from hospital, and improve the co-ordination of services following discharge from hospital and reduce the risk of hospital readmission. This is the fifth update of the original review.

OBJECTIVES

To assess the effectiveness of planning the discharge of individual patients moving from hospital.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and two trials registers on 20 April 2021. We searched two other databases up to 31 March 2020. We also conducted reference checking, citation searching and contact with study authors to identify additional studies.

SELECTION CRITERIA

Randomised trials that compared an individualised discharge plan with routine discharge that was not tailored to individual participants. Participants were hospital inpatients.

DATA COLLECTION AND ANALYSIS

Two review authors independently undertook data analysis and quality assessment using a pre-designed data extraction sheet. We grouped studies by older people with a medical condition, people recovering from surgery, and studies that recruited participants with a mix of conditions. We calculated risk ratios (RRs) for dichotomous outcomes and mean differences (MDs) for continuous data using fixed-effect meta-analysis. When combining outcome data it was not possible because of differences in the reporting of outcomes, we summarised the reported results for each trial in the text.

MAIN RESULTS

We included 33 trials (12,242 participants), four new trials included in this update. The majority of trials (N = 30) recruited participants with a medical diagnosis, average age range 60 to 84 years; four of these trials also recruited participants who were in hospital for a surgical procedure. Participants allocated to discharge planning and who were in hospital for a medical condition had a small reduction in the initial hospital length of stay (MD - 0.73, 95% confidence interval (CI) - 1.33 to - 0.12; 11 trials, 2113 participants; moderate-certainty evidence), and a relative reduction in readmission to hospital over an average of three months follow-up (RR 0.89, 95% CI 0.81 to 0.97; 17 trials, 5126 participants; moderate-certainty evidence). There was little or no difference in participant's health status (mortality at three- to nine-month follow-up: RR 1.05, 95% CI 0.85 to 1.29; 8 trials, 2721 participants; moderate certainty) functional status and psychological health measured by a range of measures, 12 studies, 2927 participants;  low certainty evidence). There was some evidence that satisfaction might be increased for patients (7 trials), caregivers (1 trial) or healthcare professionals (2 trials) (very low certainty evidence). The cost of a structured discharge plan compared with routine discharge is uncertain (7 trials recruiting 7873 participants with a medical condition; very low certainty evidence).

AUTHORS' CONCLUSIONS

A structured discharge plan that is tailored to the individual patient probably brings about a small reduction in the initial hospital length of stay and readmissions to hospital for older people with a medical condition, may slightly increase patient satisfaction with healthcare received. The impact on patient health status and healthcare resource use or cost to the health service is uncertain.

Rates of diabetic retinopathy screening in pregnant patients with type 1 and type 2 diabetes in a predominantly Indigenous Central Australian population

BACKGROUND

Pregnancy is a risk factor for the progression of diabetic retinopathy (DR) in women with pre-gestational diabetes. Australian screening guidelines recommend DR screening in the first trimester of pregnancy. The rates of DR screening in pregnant patients with pre-gestational diabetes are unknown in Australia.

AIM

To determine the rates of DR screening in pregnant women with pre-gestational diabetes at Alice Springs Hospital Diabetes Antenatal Care and Education (DANCE) clinic.

MATERIALS AND METHODS

Retrospective review of women with pre-gestational diabetes who attended the DANCE clinic between July 2016 and June 2020.

RESULTS

There were 146 pregnancies in 144 individual women included in this review. There were 93% (n = 134) who identified as Aboriginal but not Torres Strait Islander. DR screening was performed in 23 (16%) pregnancies, in which DR was present in six (26%) and no retinal abnormality was found in 17 (74%). Of seven (5%) women who had a history of DR, only three had a screen during the pregnancy period. The location of the DR screen included Alice Springs Hospital (17%, n = 4), Alice Springs general practice clinics (35%, n = 8) and remote NT community clinics outside of Alice Springs (39%, n = 9). The trimesters in which women received their DR screens were: trimester 1, 45%, n = 10; trimester 2, 39%, n = 9; trimester 3, 17%, n = 4.

CONCLUSION

The minority of pregnant women who attend the DANCE clinic at Alice Springs Hospital received DR screening in adherence with national guidelines.

"You Can't Work with My People If You Don't Know How to": Enhancing Transfer of Care from Hospital to Primary Care for Aboriginal Australians with Chronic Disease

Indigenous Australians experience significantly poorer health compared to other Australians, with chronic disease contributing to two-thirds of the health gap. We report on an evaluation of an innovative model that leverages mainstream and Aboriginal health resources to enable safe, supported transfer of care for Aboriginal adults with chronic conditions leaving hospital. The multisite evaluation was Aboriginal-led and underpinned by the principles of self-determination and equity and Indigenous research protocols. The qualitative study documented processes and captured service user and provider experiences. We found benefits for patients and their families, the hospital and the health system. The new model enhanced the patient journey and trust in the health service and was a source of staff satisfaction. Challenges included staff availability, patient identification and complexity and the broader issue of cultural safety. Critical success factors included strong governance with joint cultural and clinical leadership and enduring relationships and partnerships at the service delivery, organisation and system levels. A holistic model of care, bringing together cultural and clinical expertise and partnering with Indigenous community organisations, can enhance care coordination and safety across the hospital-community interface. It is important to consider context as well as specific program elements in design, implementation and evaluation.

The prevalence, characteristics, and risk factors of frequently readmitted patients to an internal medicine service

AIMS

To determine the prevalence, characteristics and risk factors associated with frequent readmissions to an internal medicine service at a tertiary public hospital.

METHOD

A retrospective observational study was conducted at an internal medicine service in a tertiary teaching hospital between 1st January 2010 and the 30th June 2016. Frequent readmission was defined as four or more readmissions within 12 months of discharge from the index admission. Demographic and clinical characteristics, and potential risk factors were evaluated.

RESULTS

50 515 patients were included, 1657 (3.3%) had frequent readmissions and were associated with nearly 2.5 times higher in 12-month mortality rates. They were older, had higher rates of Indigenous Australians (3.2%), more disadvantaged status (Index of Relative Socio-Economic Disadvantage decile of 5.3), and more comorbidities (mean Charlson comorbidity index 1.4) in comparison, to infrequent readmission group. The mean length of hospital stay during the index admission was 6 days for frequent readmission group (21.4% staying more than 7 days) with higher incidence of discharge against medical advice (2.0% higher). Intensive care unit admission rate was 6.6% for frequent readmission group compared to 3.9% for infrequent readmission group. Multivariate analysis showed mental disease and disorders, neoplastic, and alcohol/drug use and alcohol/drug induced organic mental disorders are associated with frequent readmission.

CONCLUSION

The risk factors associated with frequent readmission were older age, indigenous status, being socially disadvantaged, having higher comorbidities, and discharging against medical advice. Conditions that lead to frequent readmissions were mental disorders, alcohol/drug use and alcohol/drug induced organic mental disorders, and neoplastic disorders.

Predictors for Surgery-Related Emergency Department Visits within 30 Days of Foot and Ankle Surgeries

Presentation to an emergency department (ED) after foot and ankle surgeries not only causes inconvenience to patients but also increases healthcare costs. To minimize this, many major institutions have tracked these data as a part of quality improvement measures. Our previous study showed that factors associated with any (surgery-related and unrelated) postoperative ED visits were not easily modifiable by surgeons. Therefore, in the current study, we focused on factors associated specifically with surgery-related postoperative ED visits, because this may provide some insights for surgeons rather than just administrators. We examined 513 foot and ankle surgeries, of which 114 resulted in 30-day postoperative ED visits for surgery-related reasons. Demographic, medical, and surgical factors were evaluated, and risk factors were identified after adjusting for potential clinically relevant covariates. Both inpatient and outpatient surgical settings and outpatient surgical settings alone were analyzed separately. Regardless of the setting, we found that shorter surgery was protective against postoperative ED visits, as was having a previous ED visit within 6 months before surgery. In the outpatient setting, younger age and having no insurance were also proxies for a postoperative ED visit, in addition to the above factors.

Differential Impact of Malnutrition on Health Outcomes Among Indigenous and Non-Indigenous Adults Admitted to Hospital in Regional Australia-A Prospective Cohort Study

The burden of malnutrition in Indigenous people is a major health priority and this study's aims are to understand health outcomes among Indigenous and non-Indigenous patients. This cohort study includes 608 medical inpatients in three regional hospitals. Participants were screened for malnutrition using the Subjective Global Assessment tool. Hospital length of stay, discharge destination, 30-day and six-month hospital readmission and survival were measured. Although no significant difference was observed between Indigenous participants who were malnourished or nourished (p = 0.120), malnourished Indigenous participants were more likely to be readmitted back into hospital within 30 days (Relative Risk (RR) 1.53, 95% CI 1.19⁻1.97, p = 0.002) and six months (RR 1.40, 95% Confidence Interval (CI) 1.05⁻1.88, p = 0.018), and less likely to be alive at six months (RR 1.63, 95% CI 1.20⁻2.21, p = 0.015) than non-Indigenous participants. Malnutrition was associated with higher mortality (Hazards Ratio (HR) 3.32, 95% CI 1.87⁻5.89, p < 0.001) for all participants, and independent predictors for six-month mortality included being malnourished (HR 2.10, 95% CI 1.16⁻3.79, p = 0.014), advanced age (HR 1.04, 95% CI 1.02⁻1.06, p = 0.001), increased acute disease severity (Acute Physiology and Chronic Health Evaluation score, HR 1.03, 95% CI 1.01⁻1.05, p = 0.002) and higher chronic disease index (Charlson Comorbidity Index, HR 1.36, 95% CI 1.16⁻3.79, p = 0.014). Malnutrition in regional Australia is associated with increased healthcare utilization and decreased survival. New approaches to malnutrition-risk screening, increased dietetic resourcing and nutrition programs to proactively identify and address malnutrition in this context are urgently required.

Factors associated with emergency room visits within 30 days of outpatient foot and ankle surgeries

The number of emergency department (ED) visits within 30 days after elective surgery has been utilized as a quality measure by many institutions. The significance of the measure as a postoperative complication in foot and ankle surgery, and risk factors for it, are unknown. We conducted a retrospective cohort study involving 386 patients to determine risk factors associated with ED visits after outpatient foot and ankle surgeries. After adjusting for clinically relevant covariates, we found that previous ED visits within 6 months of surgery, and nonelective surgeries were associated with the postoperative ED visit. Having private insurance was protective against postoperative ED visits. Though these risk factors may not be easily modifiable by surgeons, understanding them may improve patient education and transitional care to prevent overcrowding of the ED.

Frequency and Risk of Occupational Health and Safety Hazards for Home Healthcare Workers

Given the increased prevalence of chronic disease and health care costs, more individuals are treated in the home, which has augmented the demand for more Home Healthcare Workers (HHCWs) in the field. HHCWs face multiple hazards with injury rates being more than double the national average; however, current studies on HHCWs have provided limited understanding of their occupational safety & health experiences and exposures. The aim of this study was to assess the frequency and risk of exposures through perceptions of HHCWs. The results of this study provide an initial picture of the different risks that HHCWs face daily. These findings show that studies involving HHCWs occupational safety need to be job-specific, and the proposed interventions will also likely need to be tailored by HHCWs type.
