Impact of opening a new emergency department on healthcare service and patient outcomes: analyses based on linking ambulance, emergency and hospital databases.

BACKGROUND: Emergency department (ED) crowding caused by access block is an increasing public health issue and has been associated with impaired healthcare delivery, negative patient outcomes and increased staff workload. AIM: To investigate the impact of opening a new ED on patient and healthcare service outcomes. METHODS: A 24-month time series analysis was employed using deterministically linked data from the ambulance service and three ED and hospital admission databases in Queensland, Australia. RESULTS: Total volume of ED presentations increased 18%, while local population growth increased by 3%. Healthcare service and patient outcomes at the two pre-existing hospitals did not improve. These outcomes included ambulance offload time: (Hospital A PRE: 10 min, POST: 10 min, P < 0.001; Hospital B PRE: 10 min, POST: 15 min, P < 0.001); ED length of stay: (Hospital A PRE: 242 min, POST: 246 min, P < 0.001; Hospital B PRE: 182 min, POST: 210 min, P < 0.001); and access block: (Hospital A PRE: 41%, POST: 46%, P < 0.001; Hospital B PRE: 23%, POST: 40%, P < 0.001). Time series modelling indicated that the effect was worst at the hospital furthest away from the new ED. CONCLUSIONS: An additional ED within the region saw an increase in the total volume of presentations at a rate far greater than local population growth, suggesting it either provided an unmet need or a shifting of activity from one sector to another. Future studies should examine patient decision making regarding reasons for presenting to a new or pre-existing ED. There is an inherent need to take a 'whole of health service area' approach to solve crowding issues.

Diffuse idiopathic neuroendocrine cell hyperplasia: an unusual cause of breathlessness and pulmonary nodules.

A 66-year-old woman presented with dry cough and subsequent intermittent breathlessness and wheeze. During this time she was treated by her general practitioner for chronic obstructive pulmonary disease. When her symptoms worsened and her lung function had deteriorated, a high resolution CT scan was undertaken. This showed bilateral fine nodules. Investigations did not support a diagnosis of vasculitis and sarcoidosis was suspected. A lung biopsy was performed that showed diffuse idiopathic neuroendocrine cell hyperplasia. At follow-up, to date, the patient remains symptomatic but has not progressed or developed a carcinoid tumour.

Assessment of ambulance dispatch data for surveillance of influenza-like illness in Melbourne, Australia.

OBJECTIVES: Ambulance dispatch data are collated electronically in many jurisdictions and have a wide reach into the community. They may therefore be useful for syndromic surveillance and early recognition of emerging infectious diseases. This study assessed whether ambulance dispatch data are suitable for influenza surveillance. STUDY DESIGN: Comparison of a time series of ambulance dispatch data from Melbourne, Australia for the years 1997-2005 with locum service and general practice (GP) sentinel surveillance data for influenza-like illness (ILI). METHODS: All data were aggregated into 1-week periods, corresponding to the data collection period used in the GP sentinel surveillance system, which was used as the reference system. Rates of ambulance dispatches classified to respiratory or breathing problems per 1000 total dispatches were compared with rates of callouts for flu or influenza per 1000 locum calls, and rates of ILI per 1000 patients from the sentinel GPs. Signals from the ambulance data were generated using the log likelihood ratio CUSUM, a method of continuous monitoring suitable for surveillance. RESULTS: The ambulance dispatch data displayed seasonal trends that were similar to those observed in locum service surveillance and GP sentinel systems, and identified the years with higher-than-expected seasonal ILI activity (1998 and 2003) and the epidemic year (1997). However, there was a high baseline rate of ambulance calls classified to respiratory or breathing problems (90-100 per 1000 calls) in months where there was minimal influenza activity. CONCLUSION: Ambulance dispatch data have potential for syndromic surveillance, but because of the high background noise are not definitive and would need to be calibrated to suit particular local circumstances.

Hormonal treatment and psychological function during the menopausal transition: an evaluation of the effects of conjugated estrogens/cyclic medroxyprogesterone acetate.

OBJECTIVE: To investigate the effect of hormone treatment on psychosocial distress of women during the menopausal transition (aged 40-52 years, still menstruating and with minor symptoms), in a study carefully designed to reduce bias and placebo effect. METHODS: The study was randomized, controlled by placebo, blinded to the subject, investigators and biostatistician, crossed-over after 6 months, and evaluated by a 77-item questionnaire every month for 12 months. The medication tested was continuous conjugated estrogens (Premarin) and cyclic medroxyprogesterone acetate (Provera). RESULTS: Of an eligible 105 apparently healthy women, recruited by advertisement, 83 completed the questionnaires for the study. Randomization was successful. While there was a substantial variation over time in the change of scores for all the psychosocial outcomes, there was no significant difference between active and placebo treatment when order of treatment allocation was ignored. However, a strong and consistent effect of the order of treatment allocation for many of the scores was found; in particular, the effect of active treatment was substantially stronger when it was administered second. Positive effects of active treatment were found for the score for the overall symptom rating test (p < 0.009) and its components of depression and feeling of inadequacy (p = 0.011; p = 0.001, respectively). CONCLUSIONS: The use of hormones, given as a continuous estrogen and cyclic progestogen formulation after a formal calibration/run-in period, may have a beneficial effect on psychosocial distress experienced by women towards the end of their reproductive function.

Women in medicine--socialization, stereotypes and self perceptions.

Eleven women in various specialities, including the academic and administrative spheres, were interviewed with regard to their experiences throughout their career. These women all held senior positions in Medicine and represent a broad age range (35-69 years). Information gathered during the interviews was analysed thematically in an attempt to develop a basis for further research examining predictors of success for women in medicine.
