CONCLUSIONS: Men whose prostate biopsy specimens show Gleason score 2 to 4 disease face a minimal risk of death from prostate cancer within 15 years of diagnosis. Conversely, men whose biopsy specimens show Gleason score 7 to 10 disease face a high risk of death from prostate cancer when treated conservatively, even when cancer is diagnosed as late as age 74 years. Men with Gleason score 5 or 6 tumors face a modest risk of death from prostate cancer that increases slowly over at least 15 years of follow-up.

CONCLUSIONS: Many ideal patients for beta-blocker therapy are not prescribed these drugs at discharge following AMI. The clinical and demographic characteristics of the patients do not explain much of the variation in the treatment pattern. Geographic factors and physician specialty are independently associated with the decision to use beta-blockers. Elderly patients who are prescribed beta-blockers at discharge have a better survival rate, consistent with the findings of randomized controlled trials of younger and lower-risk populations.

CONCLUSIONS: The management of airway, breathing, and circulation, and oxygen therapy and monitoring in severely ill patients before admission to intensive care units may frequently be suboptimal. Major consequences may include increased morbidity and mortality and requirement for intensive care. Possible solutions include improved teaching, establishment of medical emergency teams, and widespread debate on the structure and process of acute care.

CONCLUSION: Hospital at home care did not reduce total healthcare costs for the conditions studied in this trial, and costs were significantly increased for patients recovering from a hysterectomy and those with chronic obstructive airways disease. There was some evidence that costs were shifted to primary care for elderly medical patients and those with chronic obstructive airways disease.

PUBLICATION TYPE: JOURNAL ARTICLE
CONCLUSIONS: Hospital league tables for mortality from heart surgery will be of limited value because year to year differences in death rate can be large (odds ratio 1.5) even when the underlying risk or case mix does not change. Statistical quality control of a single series with adjustment for case mix is the only way to take into account recent performance when informing a patient of the risk of surgery at a particular hospital. If there is an increase in the number of deaths the chances of the next patient surviving surgery can be calculated from the last 16 deaths.

PUBLICATION TYPE: JOURNAL ARTICLE; META-ANALYSIS
ABSTRACT: OBJECTIVE: To quantify effect on mortality of administering human albumin or plasma protein fraction during management of critically ill patients. DESIGN: Systematic review of randomised controlled trials comparing administration of albumin or plasma protein fraction with no administration or with administration of crystalloid solution in critically ill patients with hypovolaemia, burns, or hypoalbuminaemia. SUBJECTS: 30 randomised controlled trials including 1419 randomised patients. MAIN OUTCOME MEASURE: Mortality from all causes at end of follow up for each trial. RESULTS: For each patient category the risk of death in the albumin treated group was higher than in the comparison group. For hypovolaemia the relative risk of death after albumin administration was 1.46 (95% confidence interval 0.97 to 2.22), for burns the relative risk was 2.40 (1.11 to 5.19), and for hypoalbuminaemia it was 1.69 (1.07 to 2.67). Pooled relative risk of death with albumin administration was 1.68 (1.26 to 2.23). Pooled difference in the risk of death with albumin was 6% (95% confidence interval 3% to 9%) with a fixed effects model. These data suggest that for every 17 critically ill patients treated with albumin there is one additional death. CONCLUSIONS: There is no evidence that albumin administration reduces mortality in critically ill patients with hypovolaemia, burns, or hypoalbuminaemia and a strong suggestion that it may increase mortality. These data suggest that use of human albumin in critically ill patients should be urgently reviewed and that it should not be used outside the context of rigorously conducted, randomised controlled trials.

ABSTRACT: OBJECTIVE: To evaluate an experimental heroin maintenance programme. Design: Randomised trial. SETTING: Outpatient clinic in Geneva, Switzerland. SUBJECTS: Heroin addicts recruited from the community who were socially marginalised and in poor health and had failed in at least two previous drug treatments. INTERVENTION: Patients in the experimental programme (n=27) received intravenous heroin and other health and psychosocial services. Control patients (n=24) received any other conventional drug treatment (usually methadone maintenance). Main outcome measures: Self reported drug use, health status (SF-36), and social functioning. RESULTS: 25 experimental patients completed 6 months in the programme, receiving a median of 480 mg of heroin daily. One experimental subject and 10 control subjects still used street heroin daily at follow up (difference 44%; 95% confidence interval 16% to 71%). Health status scores that improved significantly more in experimental subjects were mental health (0.58 SD; 0.07 to 1.10), role limitations due to emotional problems (0.95 SD; 0.11 to 1.79), and social functioning (0.65 SD; 0.03 to 1.26). Experimental subjects also significantly reduced their illegal income and drug expenses and committed fewer drug and property related offences. There were no benefits in terms of work, housing situation, somatic health status, and use of other drugs. Unexpectedly, only nine (38%) control subjects entered the heroin maintenance programme at follow up. CONCLUSIONS: A heroin maintenance programme is a feasible and clinically effective treatment for heroin users who fail in conventional drug treatment programmes. Even in this population, however, another attempt at methadone maintenance may be successful and help the patient to stop using injectable opioids.

ABSTRACT: OBJECTIVE: To assess the risk of perinatal death in planned home births in Australia. DESIGN: Comparison of data on planned home births during 1985-90, notified to Homebirth Australia, with national data on perinatal deaths and outcomes of home births internationally. RESULTS: 50 perinatal deaths occurred in 7002 planned home births in Australia during 1985-90: 7.1 per 1000 (95% confidence interval 5.2 to 9.1) according to Australian definitions and 6.4 per 1000 (4.6 to 8.3) according to World Health Organisation definitions. The perinatal death rate in infants weighing more than 2500 g was higher than the national average (5.7 versus 3.6 per 1000: relative risk 1.6; 1.1 to 2.4) as were intrapartum deaths not due to malformations or immaturity (2.7 versus 0.9 per 1000: 3.0; 1. 9 to 4.8). More than half (52%) of the deaths were associated with intrapartum asphyxia. CONCLUSIONS: Australian home births carried a high death rate compared with both all Australian births and home births elsewhere. The two largest contributors to the excess mortality were underestimation of the risks associated with post-term birth, twin pregnancy and breech presentation, and a lack of response to fetal distress.

ABSTRACT: OBJECTIVE: To determine the long term relative survival of all patients who had surgery for abdominal aortic aneurysm in Western Australia during 1985-94. DESIGN: Population based study. SETTING: Western Australia. SUBJECTS: All patients who had had surgery for abdominal aortic aneurysm in Western Australia during 1985-94. MAIN OUTCOME MEASURES: Morbidity and mortality data of patients admitted and surgically treated for abdominal aortic aneurysm in Western Australia during 1985-94. Elective, ruptured, and acute non-ruptured cases were analysed separately. Independent analyses for sex and patients aged 80 years or more were also undertaken. Postoperative (>30 days) relative survival was assessed against age and sex matched controls. RESULTS: Overall, 1475 (1257 men, 218 women) cases were identified. The crude five year survival after elective surgery, including deaths within 30 days of surgery, was 79% for both men and women. When compared with a matched population the five year relative survival after elective surgery was 94.9% (95% confidence interval 89.9% to 99.9%) for men but only 88.0% (76.3% to 99.7%) for women. The five year relative survival of those aged 80 years and over was good: 116.6% (89.1% to 144.0%) compared with 92.4% (87.7% to 97.0%) for those under 80 years of age (men and women combined). Cardiovascular disease caused 57.8% of the 341 deaths after 30 days. CONCLUSION: In a condition such as abdominal aortic aneurysm, which occurs in elderly patients, relative survival is more clinically meaningful than crude survival. The five year relative survival in cases of elective and ruptured abdominal aortic aneurysm was better in men than in women. This is probably because of greater comorbidity in women with abdominal aortic aneurysm and this deserves more attention in the future. The long term survival outcome in octogenarians supports surgery in selected cases.

ABSTRACT: BACKGROUND AND OBJECTIVES: Interscalene brachial plexus block is a useful technique to provide anesthesia and analgesia for the shoulder and proximal upper extremity. The initial needle direction at the interscalene groove has been described as being "perpendicular to the skin in every plane" (1). A cross-sectional (axial) approach may offer a more easily conceptualized directed needle placement. The purpose of this study is to define the cross-sectional anatomy and idealized needle angles important to interscalene brachial plexus block. METHODS: Following IRB approval, 50 patients were studied. Cross-sectional volume coil T1-weighted magnetic resonance images (MRI) were obtained from 50 patients undergoing cervical region imaging for other reasons. At the interscalene groove, a simulated needle path to contact the ventral rami or trunks of the brachial plexus was approximated at the level of C6 or C6-C7 interspace. The angle of this needle path intersecting the sagittal plane was recorded for each patient. RESULTS: The mean angle of the simulated needle path relative to sagittal plane was determined to be 61.1 +/- 6.1 degrees (range, 50-78 degrees). In 13 of 50 (26%) MRI scans, the cervical nerve roots were not visualized at the level of C6 and were measured at the C6-C7 level. CONCLUSIONS: These findings suggest initial needle placement at the interscalene groove should be angled less perpendicularly relative to the sagittal plane than is often observed. A cross-sectional approach enables more practical visualization of initial needle placement. A more accurate initial needle placement may minimize the number of needle passes necessary to contact the nerve roots, thereby more efficiently obtaining a successful block.

ABSTRACT: BACKGROUND AND OBJECTIVES: A case of permanent paraplegia is reported following attempted epidural anesthesia for a total knee replacement in a 62-year-old woman with a history of lumbar laminectomy for a prolapsed intervertebral disc. METHODS: Epidural puncture was attempted during general anesthesia and neuromuscular block. RESULTS: After four unsuccessful attempts, an epidural catheter was inserted above the upper end of the laminectomy scar. Several episodes of arterial hypotension occurred intraoperative and postoperative. Operative blood loss was minimal, and no bone glue was used. The patient awoke paraparetic with a sensory level of anesthesia to T5 bilaterally. MRI revealed an air bubble in the cord at T10 and a region of increased T2-weighted signal in the anterior aspect of the spinal cord between T4 and T5, consistent with infarction. CONCLUSION: Standards of management are discussed in relation to this case.

ABSTRACT: We report a case of paraplegia in the immediate postoperative period following right bilobectomy for carcinoma of the lung. An epidural catheter had been inserted following induction of anaesthesia and an infusion of bupivacaine 0.15% was used for postoperative pain relief. Magnetic resonance imaging failed to reveal any spinal or epidural haematoma or spinal cord ischaemia. The patient developed respiratory failure on the third postoperative day and required assisted ventilation. He was weaned from the ventilator on day 15. Two days later he sustained a cardiac arrest and died. Post-mortem examination demonstrated spinal cord infarction and severely stenosed spinal arteries. The thoracotomy position and/or intra-operative hypotension might have compromised the blood flow to the spinal cord and although suspected as a possible cause, the use of epidural analgesia was not implicated.

ABSTRACT: There are no comparisons of i.v. patient controlled analgesia (i.v. PCA) versus nurse-administered subcutaneous (NA s.c.) morphine for acute postoperative pain. We undertook a prospective, randomized, controlled clinical trial of 80 cardiac surgical patients to compare i.v. PCA with NA s.c. morphine for postoperative pain control. Visual analog scale (VAS) pain scores at rest and with movement, daily verbal pain relief scores, and side effect profiles were not significantly different. Total morphine requirements in the two groups were not significantly different. A physiotherapist's evaluation of the effectiveness of analgesia for chest physiotherapy revealed no difference between the two groups. We conclude that NA s.c. morphine, administered as required (up to hourly), is a satisfactory alternative to i.v. PCA morphine after cardiac surgery. Implications: In a prospective, randomized study, we have shown that nurse-administered subcutaneous morphine is a satisfactory alternative to i.v. patient-controlled analgesia after cardiac surgery.

CONCLUSIONS: The essential findings of the study are that remifentanil's pharmacokinetics are not appreciably different in obese versus lean subjects and that remifentanil pharmacokinetic parameters are therefore more closely related to LBM than to TBW. Clinically this means that remifentanil dosing regimens should be based on ideal body weight (or LBM) and not TBW.

CONCLUSIONS: Cortical deoxygenation during hypothermic arrest was slower after pH-stat CPB. pH-stat bypass increased the prearrest ScO2 and arrest ScO2 half-life, to increase the cortical oxygen supply and slow cortical oxygen consumption. Improved cortical physiologic recovery after hypothermic arrest was suggested with pH-stat management.
