Increased burden on metropolitan urological services: The era of the Australian National Emergency Access Targets (NEAT or the "4-h target").

BACKGROUND: The National Emergency Access Targets (NEAT) was introduced in Australia in 2011 and guides the clearance of presentations within 4-h of initial presentation from the Emergency Department (ED). We aim to assess the impact of the introduction of NEAT on acute urological services at a large metropolitan center. METHODS: A retrospective cohort study was performed and data were collected from electronic patient management systems. The control group was represented by ED presentations between June and September 2011, 1 year prior to the introduction of NEAT. The two study groups consisted of ED presentations between June and September 2012 and 2013, respectively. Outcome measures included time to the ureteric stent and scrotal exploration, inpatient length of stay (IPLOS), out-of-hours operating, and hospital mortality rates. RESULTS: Across the three study periods, a total of 76,935 patients were assessed by the EDs of the health service. 225 urological inpatient episodes were included across all periods with a trend showing increasing numbers of admissions (P = 0.003). For patients admitted under the urological service: Waiting room time and ED length of stay decreased significantly (P < 0.001). Proportion of operative cases decreased insignificantly (P = 0.275). Time from emergency presentation to emergency ureteric stent remained unchanged, however, proportions of procedures performed out-of-hours showed an increasing trend (P < 0.001). A significant increase in inter-unit transfer was observed, however, median IPLOS and mortality for operative and nonoperative cases remain unchanged. CONCLUSIONS: Concerning urological admissions, the implementation of NEAT has been associated with improvement in ED key performance indicators. Such changes have been correlated with reductions in operative cases and increases in out-of-hours emergency operating. Further research is required to evaluate the direct effect of NEAT on urological patient care.

The 'four-hour target' and the impact on Australian metropolitan acute surgical services.

BACKGROUND: The National Emergency Access Targets (NEAT), introduced in 2012, guides the clearance of emergency department (ED) presentations within 4 h of initial presentation. We aim to assess the impact of NEAT on acute surgical services at a large metropolitan centre. METHODS: A retrospective cohort study was performed and data were collected from electronic patient management systems. The control group was represented by ED presentations between June and September 2011, 1 year prior to the introduction of NEAT. The two study groups consisted of ED presentations between June and September 2012 and 2013 respectively. Outcome measures included time to appendicectomy and cholecystectomy, inpatient length of stay (IPLOS) (for operative and non-operative cases), out-of-hours operating and hospital mortality rates. RESULTS: In total, 2619 inpatient episodes were included, with a trend showing increasing admissions throughout the study periods (P < 0.001). Time to surgical review and ED length of stay decreased significantly (P < 0.001). Time from emergency presentation to emergency appendicectomy and cholecystectomy remained unchanged and procedures performed out-of-hours increased significantly from 20.9% to 42.9% (P < 0.001). Median IPLOS for operative and non-operative patients was reduced during the study from 2.05 to 1.84 days (P < 0.001). Inter-unit transfers within 48 h of presentation increased significantly from 5.3% to 14.7% (P < 0.001). CONCLUSIONS: The early results following the implementation of NEAT have been correlated with increased efficiency in ED clearance and increased burden on surgical operative and inpatient outcomes. While improvements in IPLOS were observed, they must be considered in the context of increased lower-acuity admissions and out-of-hours operating.

Cutaneous chemical burns: assessment and early management.

BACKGROUND: Chemical burns are common and may cause significant physical, psychological, social and economic burden. Despite a wide variety of potentially harmful chemicals, important general principals may be drawn in the assessment and initial management of such injuries. Early treatment of chemical burns is crucial and may reduce the period of resulting morbidity. OBJECTIVE: This article reviews the assessment and management of cutaneous chemical burns. DISCUSSION: Assessment of the patient should be rapid and occur in conjunction with early emergency management. Rapid history and pri-mary and secondary survey may be required to exclude systemic side effects of the injury. Depth of wound assessment is difficult given that necrosis caused by various chemicals can continue despite cessation of exposure. Early management should be conducted with consideration of clinician's safety, and appropriate precautions should be taken. Excluding specific situations and chemical exposure, copious irrigation with water remains the mainstay of early management. Referral to a centre of higher acuity may be required for expert evaluation.

Incidence and prevalence of non-melanoma skin cancer in Australia: A systematic review.

Non-melanoma skin cancer (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), is the most common cancer occurring in people with fair skin. Australia has been reported to have the highest incidence of NMSC in the world. Using a systematic search of the literature in EMBASE and Medline, we identified 21 studies that investigated the incidence or prevalence of NMSC in Australia. Studies published between 1948 and 2011 were identified and included in the analysis. There were six studies that were conducted on national level, two at state level and 13 at the regional level. Overall, the incidence of NMSC had steadily increased over calendar-years in Australia. The incidence of NMSC per 100,000 person-years was estimated to be 555 in 1985; 977 in 1990; 1109 in 1995; 1170 in 2002 and 2448 in 2011. The incidence was higher for men than women and higher for BCC than SCC. Incidence varied across the states of Australia, with the highest in Queensland. The prevalence of NMSC was estimated to be 2% in Australia in 2002. The incidence and prevalence of NMSC still need to be accurately established at both national and state levels to determine the costs and burden of the disease on the public health system in Australia.

Validating the use of Medicare Australia billing data to examine trends in skin cancer.

BACKGROUND:   Epidemiological data surrounding non-melanomatous skin cancer (NMSC) is highly variable, in part due to the lack of government cancer registries. Several studies employ the use of Medical Australia (MA) rebate data in assessing such trends, the validity of which has not been studied in the past. Conversely, melanoma skin cancer is a notifiable disease, and thus, MA and cancer registry data is readily available. The aim of the current study is to assess the use of MA for epidemiological measures for skin cancers, by using melanoma as a disease sample. METHODS:   Following ethics approval, data from MA and Victorian Cancer Registry (VCR) from 2004-2008 were extracted. Incidence of MA and VCR unique melanoma cases were compared and stratified by age and local government area (LGA). Regression and a paired-samples t-test were performed. RESULTS: During the study period; 15,150 and 13,886 unique melanoma patients were identified through VCR and MA data sources respectively. An outlier in the >80- year age group was noted between MA and VCR data. When stratified by age, significant correlation between MA and VCR was observed for all patients (gradient 0.91, R²= 0.936) and following exclusion of >80 patients (gradient 0.96, R²= 0.995). When stratified by LGA, a high degree of observation was observed for all patients (gradient 0.94, R²= 0.977) and following exclusion of >80 patients (gradient 0.996, R²= 0.975). CONCLUSION: Despite the inclusion of outlier data groups, acceptable correlation between MA and VCR melanoma data was observed, suggesting that MA may be suitable for assessing epidemiological trends. Such principals may be used to validate the use of MA data for similar calculations assessing NMSC trends.

Clearing emergency departments and clogging wards: National Emergency Access Target and the law of unintended consequences.

OBJECTIVE: To assess ED length of stay (EDLOS), access block, inpatient length of stay (IPLOS) and waiting times before and after the implementation of the National Emergency Access Target (NEAT). METHODS: This was designed as a retrospective cohort study and data was collected from electronic patient management systems. The control group represented all emergency presentations between June 2011 and September 2011, 1 year prior to the introduction of NEAT. The study groups were assessed and included all ED presentations between June and September 2012 and 2013 respectively. Main outcome measures were waiting times, EDLOS, proportion of patients cleared from the ED within NEAT goals, hospital length of stay and hospital mortality rates. RESULTS: A cumulative total of 76 935 patients were included in the study. During the course of the study, clearance from the ED within NEAT targets rose from 49.0% to 53.2% [relative risk (RR) 1.09; 95% CI, 1.07-1.11; P < 0.001]. ED waiting times decreased from 1.05 h [interquartile range (IQR), 0.43-2.27] to 0.45 h (IQR, 0.17-1.22) (P < 0.001) and time from bed-request to ward access increased. Utilisation of emergency short stay units (SSU) increased significantly across the study period from 6.5% to 13.4% (P < 0.001). Rates of inpatient transfers increased eightfold (RR, 7.93; 95% CI, 5.98-10.51; P < 0.001) and IPLOS increased by 21% from 2.05 (IQR, 0.75-4.96) to 2.50 days (IQR, 1.12-4.99) (P < 0.001). Hospital mortality remained unchanged from 3.0% to 3.3% (RR, 1.10; 95% CI, 0.91-1.34; P = 0.311). CONCLUSIONS: At the current institution NEAT success has been guarded, likely secondary to availability of inpatient beds. The implementation of NEAT appears to have reduced emergency waiting times. These early results suggest concurrent a detrimental effect on IPLOS; however, some of this effect may be a result of a large increase in short stay admissions.

Malignant Melanoma.

Melanomas are a major cause of premature death from cancer. The gradual decrease in rates of morbidity and mortality has occurred as a result of public health campaigns and improved rates of early diagnosis. Survival of melanoma has increased to over 90%. Management of melanoma involves a number of components: excision, tumor staging, re-excision with negative margins, adjuvant therapies (chemo, radiation or surgery), treatment of stage IV disease, follow-up examination for metastasis, lifestyle modification and counseling. Sentinel lymph node status is an important prognostic factor for survival in patients with a melanoma >1 mm. However, sentinel lymph node biopsies have received partial support due to the limited data regarding the survival advantage of complete lymph node dissection when a micrometastasis is detected in the lymph nodes. Functional mutations in the mitogen-activated pathways are commonly detected in melanomas and these influence the growth control. Therapies that target these pathways are rapidly emerging, and are being shown to increase survival rates in patients. Access to these newer agents can be gained by participation in clinical trials after referral to a multidisciplinary team for staging and re-excision of the scar.
