RESUMO

Objective Emergency general surgery (EGS) patients experience superior outcomes when cared for within an acute surgical unit (ASU) model. EGS structures in most Australian hospitals remain unknown. This study aimed to describe the national spectrum of EGS models. Methods A cross-sectional study was performed of all Australian public hospitals of medium or greater peer group (>2000 patient separations per annum). The primary outcome was the incidence of each EGS model. Secondary outcomes were the relationship of the EGS model to objective hospital variables, and qualitative reasons for the choice of model. Results Of the 120 eligible hospitals, 119 (99%) participated. Sixty-four hospitals reported using an ASU (28%) or hybrid EGS model (26%), whereas the remaining 55 (46%) used a traditional model. ASU implementation was significantly more common among hospitals of greater peer group, bed number, surgeon pool and trauma service sophistication. Leading drivers for ASU commencement were aims to improve patient care and decrease after-hours operating, whereas common barriers against uptake were insufficient EGS patient load or surgeon on-call pool. Conclusions ASU or hybrid models of care may be more widespread than currently reported. The introduction of such structures is heavily dependent on hospital and staff size, trauma subspecialisation and EGS patient throughput. What is known about the topic? Traditionally, general surgical staff were rostered to elective operating and clinic duties, with emergency patients managed on an ad hoc basis. An ASU model, with a surgeon dedicated to EGS patients, has been associated with superior outcomes. However, the Australian uptake of this model is unknown. What does this paper add? This study enrolled 119 of 120 (99%) Australian public hospitals of medium or greater peer group (>2000 patient separations per annum). Uptake of the ASU or hybrid model was more widespread than expected, existing in 64 of 119 (54%) centres. Factors for and against ASU implementation were also assessed. What are the implications for practitioners? Hospitals considering implementing an ASU or hybrid model will be reassured by the common reports of improved patient outcomes and decreased after-hours operating. However, potential hospitals must assess the suitability of the ASU model to their surgeon pool and EGS patient load.

RESUMO

Hypereosinophilic cardiomyopathy is a rare restrictive cardiomyopathy which often presents with left-sided heart failure. We present an interesting case of a 58-year-old male patient with known hypereosinophillic syndrome who had presented with congestive cardiac failure with predominant features of right-sided volume overload. Cardiac magnetic resonance imaging confirmed the diagnosis by demonstrating obliteration of the right ventricular apex and endocardial-delayed gadolinium enhancement at the mid-septal and inferior segment, at both the right ventricular and left ventricular apical region, consistent with fibrosis. He was successfully treated with intravenous diuretics to good effect. This case report demonstrates a rare clinical presentation of right ventricle involvement in hypereosinophilic cardiomyopathy and the current pathway for diagnosis with the favoured emergence of cardiac magnetic resonance imaging. All patients with hypereosinophilic syndrome should be closely monitored for signs of cardiac involvement, as early treatment carries a better prognosis.

RESUMO

BACKGROUND: The importance of the patient experience is increasingly being recognised. However, there is a dearth of studies regarding factors affecting patient-reported outcomes in emergency general surgery (EGS), including none from the Southern Hemisphere. We aim to prospectively assess factors associated with patient satisfaction in this setting. METHODS: In this prospective cross-sectional study, all consecutive adult patients admitted to an acute surgical unit over four weeks were invited to complete a validated Patient-Reported Experience Measures questionnaire. These were completed either in person when discharge was imminent or by telephone <4 weeks post-discharge. Responses were used to determine factors associated with overall patient satisfaction. RESULTS: From 146 eligible patients, 100 (68%) completed the questionnaire, with a mean overall satisfaction score of 8.3/10. On multivariate analyses, eight factors were significantly associated with increased overall satisfaction. Five of these were similar to those previously prescribed by other like studies, being patient age >50 years, sufficient analgesia, satisfaction with the level of senior medical staff, important questions answered by nurses and confidence in decisions made about treatment. Three identified factors were new: sufficient privacy in the emergency department, sufficient notice prior to discharge and feeling well looked after in hospital. CONCLUSIONS: Factors associated with patient satisfaction were identified at multiple points of the patient journey. While some of these have been reported in similar studies, most differed. Hospitals should assess factors valued by their EGS population prior to implementing initiatives to improve patient satisfaction.

RESUMO

BACKGROUND: Few studies have assessed the relationship between different emergency general surgery models and staff satisfaction, operative experience or working hours. The Royal Australasian College of Surgeons recommends maximum on-call frequency of one-in-four for surgeons and registrars. METHODS: A cross-sectional study was conducted of all medium- to major-sized Australian public hospitals offering elective general surgery. At each site, an on-call general surgery registrar and senior surgeon were invited to participate. Primary outcomes were staff satisfaction and registrar-perceived operative exposure. Secondary outcomes were working hours. RESULTS: Among eligible hospitals, 119/120 (99%) were enrolled. Compared with traditional emergency general surgery models, hybrid or acute surgical unit models were associated with greater surgeon and registrar satisfaction on quantitative (P = 0.012) and qualitative measures. Registrar-perceived operating exposure was unaffected by emergency general surgery model. Longest duration on-duty was higher among traditional structures for both registrars (mean 22 versus 15 h; P = 0.0003) and surgeons (mean 59 versus 41 h; P = 0.020). On-call frequency greater than one-in-four was more common in traditional structures for registrars (51% versus 28%; P = 0.012) but not surgeons (6% versus 0%; P = 0.089). Data on average hours per day off-duty were obtained for registrars only, and were lower in traditional structures (13 versus 15 h; P = 0.00002). CONCLUSION: Hybrid or acute surgical unit models may improve staff satisfaction without sacrificing perceived operative exposure. While average maximum duration on-duty exceeded hazardous thresholds for surgeons regardless of model, unsafe working hours for registrars were more common in traditional structures. General surgical departments should review on-call rostering to optimize staff and patient safety.

RESUMO

BACKGROUND: Macular Integrity Assessment (MAIA) microperimetry is increasingly used in clinical and research settings to assess point retinal sensitivity and fixation stability. Testing occurs under mesopic conditions, commonly after a period of dark adaptation. Our aim was to identify the minimum length of adaptation required to optimise microperimetry performance. METHODS: MAIA microperimetry using the 10-2 grid was performed on 40 right eyes of 40 healthy participants aged 18-73 with no ocular pathology and vision of at least 0.1 logMAR after ambient light exposure, with 0, 5, 10, 15, 20 and 30 min of adaptation in mesopic settings. Ten right eyes of 10 participants with choroideremia were also tested following 0 and 20 min of adaptation. We further tested 10 right eyes of 10 healthy participants after bright light exposure, with 0, 10 and 20 min of adaptation. We compared changes in threshold sensitivity and fixation stability across time points. RESULTS: Microperimetry performance did not improve with increasing adaptation time in healthy participants or patients with choroideremia after ambient light exposure. After bright light exposure, we found microperimetry thresholds improved after 10 min of adaptation, but did not improve further at 20 min. CONCLUSION: Mesopic adaptation is not required before MAIA microperimetry after exposure to ambient light. Ten minutes of adaptation is sufficient after exposure to a bright light stimulus, such as ophthalmoscopy or retinal imaging. The brief time of dark adaptation required corresponds to cone adaptation curves and provides further evidence for cone-mediated central retinal function under mesopic conditions.

RESUMO

The ectopic placement of mandibular third molars in the subcondylar region is an uncommon phenomenon. Most patients are asymptomatic but can present with acute infection or associated pathology necessitating surgical intervention. Surgical approaches have been described utilizing both extraoral and intraoral approaches to the region.This paper presents a clinical report of a patient presenting with acute fascial space infection arising from an ectopic third molar in the mandibular subcondylar region, managed with surgical removal via an endoscopically assisted intraoral approach.
