MB. I had to go to the library to check this one out. Full text was not on the web. It is very sensible. It points out that you can't just give a patient a list of options without your recommendation He gives 5 very good examples. He expects that from his car mechanic.
I had a problem at my car repair place of 45y standing where they tried to improve efficiency by having a clerk making phone bookings for surgery on my car. I did not know what operation I wanted done as I only knew the symptoms of my car's illness but not the diagnosis, prognosis and/or treatment or how long inpatient stay would be required. The girl could not help me even though her initial question to me was, "Can I help you?"
I had one and then both head-lights fail on a day that I was not in the OR till after dark. I called to have it repaired. The girl told me I could not have anything done for several days. I was then asked to be put onto the service manager whose name I still do not know. I announced myself as Michael Bookallil to which he replied, "Yes, Doctor". I explained my problem. He said, "Bring it down now doctor."
They must have had many complaints similar to mine so they replaced the girl phone answerer with a boy. That was even worse as when one calls a car repair joint one expects anyone outside the accounts department to know something about cars.
A cardiac surgeon I know said, "I believe in informed consent. I am informed and the patient consents". The next 2 abstracts are about the patient choosing cardiac surgery.

CONCLUSIONS: Propofol is effective in managing PONV with shorter PACU stay and great degree of patient satisfaction. There were two episodes of oversedation in the P-40 group. Hence, propofol at a demand dose of 20 mg seems more appropriate.
MB.I can't imagine anything sillier than trying to treat PONV with more anaesthetic. I can't remember any PONV that had an important impact at the time.
In the above study there was at first a high incidence of severe nausea which may have been due to narcotics. 2 of 22 at the higher dose of propofol became over sedated.

PUBLICATION TYPE: JOURNAL ARTICLE
CONCLUSIONS: In mechanically ventilated patients with septic shock, changes in bolus bolus injection thermodilution (TDCO) are reflected by calibrated model-simulated cardiac output (MCO) over a range of cardiac output values. A single calibration of the model appears sufficient to monitor continuous cardiac output over a 2-day period with a bias of -0.1 +/- 0.8 l/min.

AUTHOR'S ADDRESS: Department of Anesthesiology, Leiden University Medical Center, The Netherlands. E.Sarton@Anesthesiology.Medfac.LeidenUniv.nl.
PUBLICATION TYPE: JOURNAL ARTICLE
CONCLUSIONS: The data indicate the existence of sex differences in morphine-induced depression of responses mediated via the peripheral chemoreflex pathway, with more depression in women, but not of responses mediated via the central chemoreflex pathway. In men and women, morphine did not change the translation of the initial hyperventilatory response to short-term hypoxia into the secondary decrease in inspired minute ventilation (Vi) caused by sustained hypoxia.

CONCLUSIONS: Gender appears to be an important variable in recovery from general anesthesia. These findings may explain the increased reported incidence of awareness in women (three times more frequent) and support the need to include gender as a variable in pharmacokinetic and pharmacodynamic studies of anesthetic drugs.
MB. Recovery seems a bit long in both groups and the difference is trivial.
The last 3 articles investigated trivial differences in anaesthesia related to sex differences. It is difficult to find any worth-while articles in Anesthesiology.

PUBLICATION TYPE: CLINICAL TRIAL; JOURNAL ARTICLE; RANDOMIZED CONTROLLED TRIAL
CONCLUSIONS: Positive-pressure ventilation is possible with the laryngeal mask airway and cuffed oropharyngeal airway devices. Although the cuffed oropharyngeal airway can be inserted easily by inexperienced users with a high first-attempt success rate (> 90%), manipulations of the device may be required to maintain a patent airway. The laryngeal mask airway device allows positive-pressure ventilation at slightly greater peak inspiratory pressures.

CONCLUSION: Although we cannot exclude the possibility that the spinal and epidural anesthesia groups were dissimilar, the magnitudes of maternal blood pressure declines were similar after spinal or epidural anesthesia in this series of severely preeclamptic patients receiving cesarean section. Maternal and fetal outcomes also were similar.

CONCLUSIONS: Infusion of approximately 30 ml x kg(-1) x h(-1) saline during anesthesia and surgery inevitably leads to metabolic acidosis, which is not observed after administration of lactated Ringer's solution. The acidosis is associated with hyperchloremia.
MB. A trivial experiment with an obvious result if you actually understand pH.
The surgery could not have been too good as its was elective gynecology with average blood loss about 800 mls.

CONCLUSIONS: Electroencephalographic burst suppression surgery with propofol during cardiac valve replacement did not significantly reduce the incidence or severity of neurologic or neuropsychologic dysfunction. The authors' results suggest that neither cerebral metabolic suppression nor reduction in cerebral blood flow reliably provide neuroprotection during open heart surgery. Other therapeutic approaches must be evaluated to address this important medical problem.
MB. If it has no effect in patients without pryor CNS disease we can take it that it has no effect in neurosurgery or carotid operations.

RESULTS AND CONCLUSION: The advantages of an accurate assessment of a patient's risk include, on an individual level, the opportunity to give a more accurate prognosis and choose the most appropriate treatment. If the risk of an adverse outcome is known for a group of patients, the actual outcome can be compared with the predicted outcome, and comparison can be made between groups in different surgical units for the purposes of audit or research. The Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) is the most appropriate of the currently available scores for general surgical practice.

PUBLICATION TYPE: JOURNAL ARTICLE
ABSTRACT: BACKGROUND: Recent recommendations for the reorganization of cancer services emphasize the importance of a 'minimal acceptable volume of work'. The influence of both hospital and surgical workload has been examined using a population-based series of patients with colorectal cancer. METHODS: Nine hundred and twenty-seven patients with primary colorectal cancer diagnosed during the period 1 January to 30 June 1993 were identified from the North Western Regional Cancer Registry. Case notes were reviewed for information on patient age and sex, histological diagnosis, disease stage, degree of tumour differentiation, mode of admission, identity of operating surgeon, timing of operative procedure, and use of radiotherapy and/or chemotherapy. A multivariate Cox proportional hazards model was then constructed to examine, simultaneously, the effects of patient-, disease- and health service-related variables on survival. RESULTS: Age, tumour stage and differentiation, and mode of admission were revealed as significant independent prognostic variables. After adjusting for these variables, neither operator grade (consultant versus junior), consultant workload nor hospital throughput were identified as independently influencing patient survival. CONCLUSION: The results of this study do not support an association between volume of work and patient outcome.
MB. I think other similar studies have shown differences. There are suspicious parts of this study eg those that had the biggest throughput did less preoperative assessment. The conclusion does not say that there is no difference.

ARTICLE TITLE: Endoleak after stent-graft treatment of abdominal aortic aneurysm: a meta-analysis of clinical studies.

AUTHOR'S ADDRESS: Department of Surgery, Leiden University Medical Centre, Leiden, The Netherlands.
PUBLICATION TYPE: JOURNAL ARTICLE; META-ANALYSIS
ABSTRACT: BACKGROUND: Endoleak is the major complication after endovascular treatment of abdominal aortic aneurysm (AAA) and its incidence seems to remain significant. Little is known about the association of device type and configuration with respect to the incidence, location, time of onset and fate of endoleakage. METHODS: A meta-analysis was performed via a Medline search of clinical studies after 1995 dealing with the endovascular treatment of AAA. Details of number of patients treated, configuration and type of endovascular device were collected. Data concerning site of origin, time of occurrence and fate of the endoleak were retrieved, along with information on change in diameter of the aneurysm with time. RESULTS: The 23 publications included reported on 1189 patients. The 1118 patients with successfully inserted transfemoral endovascular grafts experienced 270 endoleaks (24 per cent). The majority arose from the distal stent attachment site (36 per cent), were present immediately after stent-graft placement (66 per cent) and were persistent in time (37 per cent). Tube grafts were more frequently affected by endoleakage (35 per cent; P < 0.0001), especially at the distal stent attachment site (51 per cent), than bifurcated grafts (18 per cent; P = 0.004) and aortounilateral devices (20 per cent; P = 0.70). Self- expandable stent-grafts were more frequently associated with endoleaks (25 per cent) than balloon-expandable stent-grafts (17 per cent) (P = 0.037). CONCLUSION: Endovascular treatment of AAA is an evolving field. Even after the initial learning curve and attention to device-related problems, it is still accompanied by a significant number of endoleaks. Uniform presentation of results of treatment is necessary for analysing the effect of differences between patients, aneurysm morphology and device type.
MB.We seem to be using a different device each time I anaesthetise one of these. The average number in each of the studies was 49. It would take a long time for any starting group to get constant results. I don't think the statistics quoted would mean much.
At the time our group was quoted as having done 37 with the average 24% endoleak. We have now done over 400. The leaks would now be about 10%.

PUBLICATION TYPE: JOURNAL ARTICLE
ABSTRACT: BACKGROUND: This prospective study compared morbidity and mortality rates following conventional and endovascular abdominal aortic aneurysm (AAA) repair using a physiological scoring system. METHODS: Between December 1994 and November 1997, 104 elective open aneurysm repairs and 49 endovascular aneurysm repairs were performed. These patient cohorts were compared using the Portsmouth predictor equation (P-POSSUM) scoring system. Data collected prospectively from patient notes were used to obtain physiological and operative severity scores which were analysed to compare expected and observed mortality and morbidity rates. RESULTS: There were three deaths (6 per cent) in the endovascular AAA repair group and 17 (16 per cent) in the conventional aneurysm repair group, whereas the P-POSSUM formulae predicted mortality rates of 8 and 19 per cent respectively. Although the mean physiological scores were similar for both groups (endovascular 20.8 versus conventional 20.1), the operative severity score was significantly greater in the conventional group (26.3 versus 19.7; P < 0.001). CONCLUSION: In this study open aortic aneurysm repair had a higher operative severity than endovascular repair, which was reflected in the increased mortality rate.
MB. Mortality of open operations seems a bit high

CONCLUSIONS: Estimated PSA control rates in this pooled analysis are similar to those of single institutions. These rates indicate the probability of success for subsets of patients with tumors of several prognostic category groupings. These results represent a multi-institutional benchmark for evidence-based counseling of prostate cancer patients about radiation treatment.

CONCLUSIONS: Increasing detection of presymptomatic tumors by imaging procedures, such as ultrasonography, computed tomography, and magnetic resonance imaging, does not fully explain the upward incidence trends of renal cell carcinoma. Other factors may be contributing to the rapidly increasing incidence of renal cell cancer in the United States, particularly among blacks.

ABSTRACT: CONTEXT: Liver transplantation is among the most costly of medical services, yet few studies have addressed the relationship between the resources utilized for this procedure and specific patient characteristics and clinical practices. OBJECTIVE: To assess the association of pretransplant patient characteristics and clinical practices with hospital resource utilization. DESIGN: Prospective cohort of patients who received liver transplants between January 1991 and July 1994. SETTING: University of California, San Francisco; Mayo Clinic, Rochester, Minn; and the University of Nebraska, Omaha. PATIENTS: Seven hundred eleven patients who received single-organ liver transplants, were at least 16 years old, and had nonfulminant liver disease. MAIN OUTCOME MEASURE: Standardized resource utilization derived from a database created by matching all services to a single price list. RESULTS: Higher adjusted resource utilization was associated with donor age of 60 years or older (28% [$53813] greater mean resource utilization; P=.005); recipient age of 60 years or older (17% [$32795]; P=.01); alcoholic liver disease (26% [$49596]; P=.002); Child-Pugh class C (41% [$67 658]; P<.001); care from the intensive care unit at time of transplant (42% [$77833]; P<.001); death in the hospital (35% [$67 076]; P<.001); and having multiple liver transplants during the index hospitalization (154% increase [$474 740 vs $186 726 for 1 transplant]; P<.001). Adjusted length of stay and resource utilization also differed significantly among transplant centers. CONCLUSIONS: Clinical, economic, and ethical dilemmas in liver transplantation are highlighted by these findings. Recipients who were older, had alcoholic liver disease, or were severely ill were the most expensive to treat; this suggests that organ allocation criteria may affect transplant costs. Clinical practices and resource utilization varied considerably among transplant centers; methods to reduce variation in practice patterns, such as clinical guidelines, might lower costs while maintaining quality of care.
MB. This would be very difficult to do. Spin off benefits ie skills and methods developed for this operation will be otherwise useful eg in blood replacement in major trauma.

ABSTRACT: CONTEXT: Studies have shown that an inflammatory response may be elicited by mechanical ventilation used for recruitment or derecruitment of collapsed lung units or to overdistend alveolar regions, and that a lung-protective strategy may reduce this response. OBJECTIVE: To test the hypothesis that mechanical ventilation induces a pulmonary and systemic cytokine response that can be minimized by limiting recruitment or derecruitment and overdistention. CONCLUSIONS: Mechanical ventilation can induce a cytokine response that may be attenuated by a strategy to minimize overdistention and recruitment/derecruitment of the lung. Whether these physiological improvements are associated with improvements in clinical end points should be determined in future studies.

RESULTS: Chronic symptomatic hyponatremia (mean [SD] sodium level 111 [12] mmol/L) was present for 5.2 [4.5] days. Death or major morbidity occurred in 44 (83%) of 53 patients, including 10 with orthopedic injury. Twelve patients had hypoxemia (PO2 = 63 [25] mm Hg) and cerebral edema. Among patients who received IV sodium chloride before respiratory insufficiency, plasma sodium levels were increased by 22 (10) mmol/L in 35 hours and patients had a CPC of 1.0 (normal or slight disability). Among patients who received IV sodium chloride after respiratory insufficiency, plasma sodium levels were increased by 30 (6) mmol/L in 41 hours and patients had a CPC of 3.0 (1.2) (severe disability). Among patients who had fluid restriction only, plasma sodium levels were increased by 3 (2) mmol/L in 41 hours and patients had a CPC of 4.6 (0.7) (4 = persistent vegetative state; 5 = death). The outcomes did not correlate with either the initial plasma sodium level (r=0.05, P>.12) or the rate of correction (r=0.31, P>.10). CONCLUSIONS: Chronic symptomatic hyponatremia in postmenopausal women can be associated with major morbidity and mortality. Therapy with IV sodium chloride was associated with significantly better outcomes than fluid restriction.
MB. I always thought the physicians have always got this subject wrong. The serum Na could be low but urine osmolality high without those paramaters being inappropriate. Those who were fluid restricted after developing resiratory failure all died .They did/do not seem to realise that there could for example be dehydration with low CVP. None of the literature on inappropriate ADH secretion, which was the label put onto some of the cases, indicate state of body water as shown by changes in weight. I am sure some cases of postoperative hyponatraemia are due to giving IV fluids with low or no Na content. Not many anaesthetists do that now.

ABSTRACT: Mild hypothermia is assumed to protect against secondary brain injury. However, the accuracy of brain temperature estimation remains debatable if direct measurement in the target area is to be avoided or is impossible. Furthermore, intracerebral temperature gradients exist, especially under intraoperative conditions. We aimed to establish how brain surface temperatures (TBrain) relate to temperatures taken at standard sites in posterior fossa surgery. Ten patients undergoing cerebellopontine angle tumor removal were monitored for TBrain, esophageal temperature (TEso), bladder temperature (TBlad), ipsi- and contralateral tympanic membrane (TTymp-I, TTymp-C), and scalp temperatures (TScalp). During monitoring, TEso increased from 35.3+/-0.2 degrees C to 36.0+/-0.3 degrees C. After dura opening, TBrain was -0.14+/-0.1 degrees C below TEso. At the end of tumor removal, this difference increased to -0.43+/-0.31 degrees C (P < 0.05). TTymp-C was -0.29+/-0.18 degrees C below TBrain at dura opening. TTymp-C reflected the behavior of TEso adequately (r = 0.938), however, with a mean difference of -0.39+/-0.04 degrees C. In contrast, TTymp-I readings closely followed temperature changes in the area of surgery. TBlad reflected TEso except in periods of rapid temperature changes. In posterior fossa (PF) surgery, local TBrain is most accurately reflected by TEso. For clinical use TBlad and TTymp-C are also sufficient to assess brain surface temperature in the PF. Intraoperative surface cooling of the brainstem is less than the previously described cooling rate of exposed cerebral cortex.
MB. The differences look small to me.

ABSTRACT: We have studied 46 patients to compare the efficacy of the auditory evoked potential (AEP) index, bispectral index (BIS), 95% spectral edge frequency (SEF) and median frequency (MF) in predicting movement in response to insertion of the laryngeal mask airway (LMA). Anaesthesia was induced with target-controlled infusions of propofol and alfentanil. After loss of eyelash reflex and adequate jaw relaxation, the LMA was inserted without the assistance of a laryngoscope or neuromuscular blocker. Patients who showed any visible spontaneous muscle movement within 1 min of LMA insertion were defined as movers. Values in movers and non-movers at 30 s before LMA insertion were analysed. Only AEP index discriminated between movers and non-movers with a prediction probability of 0.872. BIS, SEF and MF could not predict movement at LMA insertion. AEP index was the most reliable predictor of movement in response to LMA insertion.

ABSTRACT: Hyperkalaemia with ECG changes had been noted during prolonged carbon dioxide pneumoperitoneum in pigs. We have compared plasma potassium concentrations during surgery in 11 patients allocated randomly to undergo either laparoscopic or open appendectomy and in another 17 patients allocated randomly to either carbon dioxide pneumoperitoneum or abdominal wall lifting for laparoscopic colectomy. Despite an increasing metabolic acidosis, prolonged carbon dioxide pneumoperitoneum resulted in only a slight increase in plasma potassium concentrations, which was both statistically and clinically insignificant. Thus hyperkalaemia is unlikely to develop in patients with normal renal function undergoing carbon dioxide pneumoperitoneum for laparoscopic surgery.

ABSTRACT: Respiratory function, assessed by pre- and postoperative spirometry, and overnight pulse oximetry recordings, was compared prospectively in patients undergoing infrarenal abdominal aortic aneurysm repair by endovascular or conventional surgery. Episodic hypoxaemia was common in both groups before operation and up to the fifth night after operation. The frequency and severity of hypoxaemia were greater in the conventional group (P < 0.05). FEV1 and FVC decreased significantly on the third and fifth days after operation in both groups (P < 0.05); decreases in FVC were greater in patients undergoing conventional surgery. On the fifth day after operation, FVC had recovered to 86% and 64% of preoperative values in the endovascular and conventional groups, respectively (P < 0.05). Duration of surgery was greater (P < 0.05) and duration of postoperative artificial ventilation significantly less (P < 0.05) after endovascular repair. Postoperative PCA morphine consumption and duration of use were significantly greater (P < 0.05) in patients undergoing conventional abdominal aortic aneurysm surgery.

ABSTRACT: The potential for serious complications after venous air embolism and successful malpractice liability claims are the principle reasons for the dramatic decline in the use of the sitting position in neurosurgical practice. Although there have been several studies substantiating the relative safety compared with the prone or park bench positions, its use will continue to decline as neurosurgeons abandon its application and trainees in neurosurgery are not exposed to its relative merits. How can individual surgeons continue to use this position? Will individual, difficult surgical access cases be denied the obvious technical advantages of the sitting position? Limited use of the sitting position should remain in the neurosurgeon's armamentarium. However, several caveats must be emphasized. Assessment of the relative risk-benefit, based on the individual patient's physical status and surgical implications for the particular intracranial pathology, is of paramount importance. The patient should be informed of the specific risks of venous air embolism, quadriparesis and peripheral nerve palsies. Appropriate charting of patient information provided and special consent issues are essential. An anaesthetic input into the decision to use the sitting position is a sine qua non. The presence of a patient foramen ovale is an absolute contraindication. Preoperative contrast echocardiography should be used as a screening technique to detect the population at risk of paradoxical air embolism caused by the presence of a patent foramen ovale. The technique involves i.v. injection of saline agitated with air and a Valsalva manoeuvre is applied and released. Use of this position necessitates supplementary monitoring to promptly detect and treat venous air embolism. Doppler ultrasonography is the most sensitive of the generally available monitors to detect intracardiac air. The use of a central venous catheter is recommended, with the tip positioned close to the superior vena cava junction with the right atrium, to aspirate intravascular gas. Measures to minimize hypotension associated with the sitting position include a slow, staged positioning over 5-10 min and use of the 'G suit' inflated with compressed air applied to the lower extremities and pelvis. Use of the sitting or upright position for patients undergoing posterior fossa and cervical spine surgery presents unique challenges for the anaesthetist. With appropriate patient selection and preparation, and using prudent intraoperative monitoring and anaesthetic techniques, selected patients should still benefit from the optimum access to mid-line lesions, improved cerebral venous decompression, lower intracranial pressure and enhanced gravity drainage of blood and CSF associated with the sitting position.
MB. I stopped them using the sitting position in about 1970.

ABSTRACT: The evoked electromyogram often decreases during anaesthesia in the absence of neuromuscular block. We have measured the electromyogram of the first dorsal interosseous muscle evoked by train-of-four stimulation of the ulnar nerve in 63 patients undergoing anaesthesia for minor surgery. We used Medicotest P-00-S electrodes, a Datex Relaxograph and a current sink in the stimulating leads in parallel with the current path through the patient. The current sink was used to shunt some of the maximum available output current from the Relaxograph while maintaining the supramaximal stimulus current passing through the patient. After 30 min of anaesthesia, when the muscle response to train-of-four was stable, the ulnar nerve stimulus current was increased by reducing the proportion shunted through the current sink. The electromyographic response did not change during the study in 13 patients. In the remaining 50 patients, the response decreased to 78.4% (SD 27.1%, range 7.5-95.0%) of baseline values over the first 20 min of anaesthesia. In 22 of these patients, the electromyographic response increased from 71.4 (SD 22.6)% to 92.3 (9.5)% of baseline responses when the stimulus current was increased by 12.3 (2.4) mA, while in the remaining 28 patients the response decreased to 83.7 (10.6)% and did not increase with increasing stimulus current. These results suggest that loss of supramaximal stimulation is partly responsible for the observed changes in the evoked electromyogram during anaesthesia.

ABSTRACT: Midazolam is often used for paediatric premedication. We have compared two methods of administering midazolam intranasally in 44 surgical day-case children allocated randomly to receive midazolam 0.2 mg kg-1 as drops or midazolam 0.1 mg kg-1 from an intranasal spray device. Behaviour was recorded on a four-point scale by the parent, nurse and anaesthetist. Coefficients were obtained representing the change in behaviour score. There was no significant difference in method of administration (coefficient 0.13, P = 0.39). Children were significantly more distressed at the time of premedication and at the time of venous cannulation (coefficients 1.31 and 0.70) than at baseline. There was no significant difference in the assessments between observers. Midazolam by either method was equally effective but acceptability of the premedication was poor in both groups. Intranasal midazolam cannot be recommended as a method for routine premedication of young children.

PUBLICATION TYPE: JOURNAL ARTICLE
ABSTRACT: A two-compartment model of temperature distribution estimates the core compartment to occupy 66% of body mass at rest, while the peripheral compartment comprises the remainder. General anaesthesia impairs thermoregulation by central and peripheral actions. Peripheral vasodilatation accelerates heat transfer from the core to peripheral compartment causing the core compartment to cool and expand in size. Core hypothermia may be a significant cause of postoperative morbidity. This undocumented change in the size of the core compartment on induction of anaesthesia can be calculated. Core size increased from the established value of 66% before induction of general anaesthesia to 71.2 (SD 6)% of body mass, 20 min after induction of anaesthesia (P = 0.0001). On induction of general anaesthesia, the core compartment cools and expands while the peripheral compartment warms and contracts by a corresponding amount. Measurement of the magnitude of changes in core:periphery heat distribution on induction of anaesthesia contribute to a clearer understanding of the pathophysiology of perioperative hypothermia.
MB. I think that the concept of heat compartments which change in size is a bit contrived.

ABSTRACT: The water analogue provides a visual model of the process of anaesthetic exchange. In the standard version, a single pipe connects the mouth container to the lung container and the conductance of this mouth-lung pipe is proportional to alveolar ventilation. This implies that inspired and expired ventilations are equal. In fact, with high inspired concentrations of nitrous oxide, early rapid uptake of gas by solution leads to a substantial difference between inspired and expired ventilation which in turn leads to concentration and second-gas effects. It is shown that by representing inspired and expired ventilations separately, and keeping one of them constant while varying the other to compensate for rapid uptake, concentration and second-gas effects are reproduced in the water analogue. Other means of reproducing the effects are reported but we believe that the first method is the most realistic and the most appropriate for teaching.

The NSW Director-general of Health (not a doctor) can't work out how winter has moved to November (SMH page 4). 5 Sydney teaching hospitals including us closed their emergency departments at the same time. All the political players are blaming the rest of the players

The significant improvement in angina symptoms and perceived health status (PHS) after CABG persists for at least 5 years. However, only one third of patients in this geographical area return to work, and this is not solely dependent on clinical symptoms.

ABSTRACT: We reviewed the published and unpublished international literature to determine the influence of salaried payment on doctor behaviour. We systematically searched Medline, BIDS Embase, Econlit and BIDS ISI and the reference lists of located papers to identify relevant empirical studies comparing salaried doctors with those paid by alternative methods. Only studies which reported objective outcomes and measures of the behaviour of doctors paid by salary compared to an alternative method were included in the review. Twenty-three papers were identified as meeting the selection criteria. Only one of the studies in this review reported a proxy for health status, but none examined whether salaried doctors differentiated between patients on the basis of health needs. Therefore, we were unable to draw conclusions on the likely impact of salaried payment on efficiency and equity. However, the limited evidence in our review does suggest that payment by salaries is associated with the lowest use of tests, and referrals compared with FFS and capitation. Salary payment is also associated with lower numbers of procedures per patient, lower throughput of patients per doctor, longer consultations, more preventive care and different patterns of consultation compared with FFS payment.
MB. Someone told me they pay sheep shearers by the fleece but all their support staff by salary.

CONCLUSIONS: Our data suggest that a specialized outpatient clinic can improve practice patterns in patients with CHF. The high mortality risk in CHF with preserved systolic function suggests the need to find efficacious (and effective) therapies for this condition.

CONCLUSIONS: These data show that cardiac troponin T is increased in patients with congestive heart failure and that the level parallels the severity of the disease. We conclude that cardiac troponin T is a suitable candidate-marker molecule to monitor congestive heart failure from a structural perspective.

CONCLUSION: Postoperative CABG atrial fibrillation is associated with prolonged hospital stay and increased cost. Prophylactic oral amiodarone did not statistically alter the incidence or duration of atrial fibrillation after CABG, although favorable trends were noted. Hospital cost was not affected by therapy with amiodarone.

CONCLUSION: Procedural complications account for half of all post- percutaneous coronary angioplasty (PTCA) deaths and are a particular problem for women. Other deaths are more directly related to patient acuity or noncardiac, comorbid conditions. Understanding why women face an increased risk of procedural complications may lead to improved outcomes for all patients.
MB. I thought it was due to smaller size of vessels. The following editorial implies this when they state that when earlier studies of CABG mortality were corrected for body size the sex difference went away. How come I know this. :- (
