The fate of AAA patients referred electively to vascular surgical unit

BACKGROUND

The ideal treatment of abdominal aortic aneurysms (AAA) is to operate aneurysms likely to rupture, without exposing other cases to major surgery. The purpose here was to analyse retrospectively the management of AAA in a well-defined geographical region in the 1990's.

METHODS

194 new vascular surgical outpatient consultations due to AAA were done to the regional vascular centre during the years 1990, 1992, 1994, 1996 and 1998. Data were collected from case records. Statistics Finland provided causes and dates of death.

RESULTS

The mean observed annual AAA incidence was 9.0 per 100 000 inhabitants and it rose significantly (33.3%) during the study period. The duration of follow-up varied between 0 and 129 months. The 5/8-year cumulative mortality was 37.3/50.7%. The most common causes of death were AAA-related (31.7%), cardiac (29.1%) or malignancy (19.0%). Twenty-five patients with small AAA were referred to primary health care sector for further follow-up. There were no RAAA (ruptured AAA) deaths in this group. The cumulative 5/8-year mortality was 43.2/49.9%. One hundred patients underwent an elective aneurysm repair with in-hospital mortality of 7.0%. The cumulative 5/8-year mortality was 23.7/35.4%. Twelve patients refused elective treatment. The cumulative 5/8-year mortality was 45.1/ 63.4% and 5/7 deaths were due to RAAA. Twenty-three patients were unfit for elective repair. The cumulative 5/8-year mortality was 87.0%/100% and 5/20 deaths were caused by RAAA. The cumulative 5/8-year RAAA-rate in the patients with AAA more than 5.0 cm in diameter and outside elective aneurysm-repair (n = 23) was 51.9%/100.0%.

CONCLUSION

The observed incidence of AAA increased during the 1990's. Half of the patients underwent an elective procedure. Patients unfit for surgery died mainly for other reasons than RAAA. Most patients with AAA over 5.5 cm not subjected to elective procedure, died of rupture.

Decision making in terminal care: a survey of finnish doctors' treatment decisions in end-of-life scenarios involving a terminal cancer and a terminal dementia patient

GOALS

The physicians' decision-making process in terminal care is complex: medical, ethical, legal and psychological aspects are all involved, particularly in critical situations. Here, a study was made of the association of personal background factors with end-of-life decisions.

METHODS

A questionnaire was sent to 300 surgeons, 300 internists, 500 health centre practitioners (GPs) and all 82 Finnish oncologists. The response rate was 62%. Two scenarios were presented: one involving a terminal cancer patient, the other a dementia patient. Sociodemographic factors, general life values and attitudes related to end-of-life care were asked.

MAIN RESULTS

In the cancer case (Scenario 1) 17%, and in the dementia case (Scenario 2) 43% of all the respondents chose active treatment. In a logistic regression analysis of treatment decisions in Scenario 1, physician's age, specialty, marital status and attitudes to assisted suicide and withdrawal of life-sustaining treatment (LST) entered the model. In Scenario 2, the variables were physician's age, physician's own experience of severe disease in the family, attitude to withdrawal of LST and opinion of advanced directives.

CONCLUSIONS

Doctors' end-of-life decisions vary widely according to personal background factors. The findings underline the importance of advance communication, making these decisions in accordance with the patient's wishes.

Factors affecting physicians' decisions to forgo life-sustaining treatments in terminal care

OBJECTIVES

Treatment decisions in ethically complex situations are known to depend on a physician's personal characteristics and medical experience. We sought to study variability in decisions to withdraw or withhold specific life-supporting treatments in terminal care and to evaluate the association between decisions and such background factors.

DESIGN

Readiness to withdraw or withhold treatment options was studied using a terminal cancer patient scenario with alternatives. Physicians were asked about their attitudes, life values, experience, and training; sociodemographic data were also collected.

SETTING

Finnish physicians, postal survey.

SURVEY SAMPLE

Five hundred general practitioners, 300 surgeons, 300 internists, and 82 oncologists.

RESULTS

Treatments most often forgone were blood transfusion (82%) and thrombosis prophylaxis (81%). Least willingly abandoned were intravenous (i.v.) hydration (29%) and supplementary oxygen (13%). Female doctors were less likely to discontinue thrombosis prophylaxis (p=0.022) and supplementary oxygen (p<0.001), but more readily x ray (p=0.039) and laboratory (p=0.057) examinations. Young doctors were more likely to continue antibiotics (p=0.025), thrombosis prophylaxis (p=0.006), supplementary oxygen (p=0.004) and laboratory tests (p=0.041). Oncologists comprised the specialty most ready to forgo all studied treatments except antibiotics and blood transfusion. The family's wishes (alternative 1) significantly increased treatment activity. Young and female practitioners and oncologists were most influenced by family appeal. Advance directives (alternative 2) made decisions significantly more reserved and uniform. Different factors in the physician's background were found to predict decisions to withdraw antibiotics or i.v. hydration.

CONCLUSION

The considerable variation observed in doctors' decisions to forgo specific life-sustaining treatments (LST) was seen to depend on their personal background factors. Experience, supervision, and postgraduate education seemed to be associated with more reserved treatment decisions. To increase the objectivity of end of life decisions, training, and research are of prime significance in this ethically complex area of medicine.

Visual analogue scale, urinary incontinence severity score and 15 D--psychometric testing of three different health-related quality-of-life instruments for urinary incontinent women

OBJECTIVE

The purpose of this study is psychometric assessment of disease-specific questionnaire, Urinary Incontinence Severity Score (UISS) and Visual Analogue Scale (VAS) in urinary incontinent women. We also investigated functional relationship between UISS, VAS and 15D-valid, generic health-related quality-of-life (HRQoL) instrument.

MATERIALS AND METHODS

Eighty-two incontinent female patients were recruited for the study that included baseline investigation and re-evaluation 13 months (range 6-21 months) after treatment. Twenty-nine control women who had urinary incontinence but were not bothered by it completed the HRQoL measurements.

RESULTS

Internal consistency and content validity of UISS was good. Both measures UISS and VAS were reproducible, Spearman's rank correlation between test-retest were 0.88 and 0.85 respectively. The control women's UISS, 15D and VAS scores were significantly lower than the patient's scores (p<0.001, Mann-Whitney U test) which proves to be a good discriminant. The changes in pad test correlated moderately well with those in the VAS and UISS. The UISS, VAS and 15D in the improved group had responsiveness (Guyatt's) statistics: 1.48, 1.74 and -0.80 respectively.

CONCLUSION

The UISS and VAS proved to be valid, reproducible and responsive to treatment for UI women. The functionality of the 15D was good but it demonstrated less sensitivity to changes after treatment.

Validity of the new American College of Rheumatology criteria for neuropsychiatric lupus syndromes: a population-based evaluation

OBJECTIVE

To assess the validity of the recently developed American College of Rheumatology (ACR) nomenclature for neuropsychiatric systemic lupus erythematosus (NPSLE).

METHODS

We conducted a cross-sectional, population-based study covering an area with 440,000 people. A total of 46 patients aged 16 to 65 years fulfilled the criteria for a definite diagnosis of SLE. One control for each patient matched by age, sex, education, and place of residence was randomly identified from the population register. All patients and controls underwent a clinical neurologic examination and neuropsychological testing. The data were analyzed using conditional logistic regression methods.

RESULTS

Forty-two patients (91%) and 25 controls (56%) fulfilled at least one of the ACR NPSLE criteria, which gave an odds ratio (OR) of 9.5 (95% confidence interval [CI] 2.2-40.8) but low specificity (0.46). Cognitive dysfunction was the most common syndrome detected in 37 patients (80%). A revised set of 16 criteria excluding the syndromes without evidence for neuronal damage resulted in improved specificity (OR 7.0, 95% CI 2.1-23.5, specificity 0.93).

CONCLUSION

The proposed 19 ACR criteria did not differentiate SLE patients from controls, nor NPSLE patients from other SLE patients. The revised NPSLE criteria proposed by us performed well in our population but should be evaluated in a larger patient population.

Cytokine responses and myocardial injury in coronary artery bypass grafting

OBJECTIVE

Cardiopulmonary bypass is acknowledged to be one of the major causes of a complex systemic inflammatory response after cardiac surgery, and it may contribute to postoperative complications and even multiple organ dysfunction. We here compared the cytokine responses and the degree of myocardial injury after coronary artery bypass grafting with or without cardiopulmonary bypass.

METHODS

Nine patients underwent off-pump revascularization and 13 with cardiopulmonary bypass. Plasma levels of tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-6, IL-8 and IL-10 were measured before anesthesia induction, and 5 min, 1, 4, and 20 h after reperfusion to the myocardium. Levels of the MB isoenzyme of creatine kinase (CK-MB) were also measured after the operation.

RESULTS

Levels of TNF-alpha were low in both groups. A delayed elevation of IL-6 was noted in the off-pump group. IL-8 and IL-10 levels were significantly higher in the CPB than in the off-pump patients after reperfusion (p=0.006 and 0.001 respectively). Postoperative CK-MB levels were significantly higher in the CPB than in the off-pump group (p=0.001). Cytokine levels correlated with CK-MB values.

CONCLUSION

The results indicated that off-pump revascularization was associated with reduced cytokine responses and less severe myocardial injury. The degree of myocardial injury, as defined by CK-MB release, correlated with cytokine release. Intervention designed to reduce cytokine responses in cardiac surgery may be advantageous for patients with severe comorbidity.

Anti-inflammatory effects of 17beta-estradiol pretreatment in men after coronary artery surgery

OBJECTIVE

To investigate the anti-inflammatory and hemodynamic effects of 17beta-estradiol in men undergoing elective coronary artery bypass graft surgery (CABG).

DESIGN

Prospective, randomized, controlled.

SETTING

Operating room and intensive care unit in a university hospital.

PARTICIPANTS

Twenty-one men undergoing primary, elective CABG surgery.

INTERVENTION

17beta-estradiol, 2mg, was given orally twice in 14 hours before the operation.

MEASUREMENTS AND MAIN RESULTS

Leukocyte counts, plasma myeloperoxidase, tumor necrosis factor-alpha, interleukin (IL)-6, IL-8, and IL-10 were measured perioperatively. Leukocyte counts were lower in the 17beta-estradiol group than in controls at 6 hours (11.4 +/- 2.0 hours v 15.5 +/- 4.7 hours x 10(9)/L) and 20 hours (11.6 +/- 1.9 hours v 13.6 +/- 2.5 hours x 10(9)/L) after reperfusion (p = 0.03). The release of myeloperoxidase was lower in the 17beta-estradiol group than in controls (5 minutes; 634.4 +/- 213.1 microg/mL v 773.1 +/- 209.3 microg/mL; 4 hours, 305.0 +/- 108.0 microg/mL v 441.3 +/- 191.6 microg/mL; p = 0.02). Systemic vascular resistance index was lower just after cardiopulmonary bypass, and cardiac index was higher postoperatively in the 17beta-estradiol group as compared with controls.

CONCLUSION

Pretreatment with 17beta-estradiol can limit leukocyte activation in men after CABG surgery.

To resuscitate or not: a dilemma in terminal cancer care

One of the difficult dilemmas in terminal care is the decision on whether to start or withhold cardiopulmonary resuscitation (CPR). Is this decision made on purely medical grounds, or is it also influenced by the physician's personal characteristics or education? The aim of this study was to look at factors affecting this decision. A questionnaire was sent out to a stratified sample of 1180 Finnish doctors. The response rate was 62%. The physicians were asked whether they would (a) start CPR or (b) withhold CPR in a scenario describing the unexpected death of a young terminal cancer patient. Data were also collected on demographics, post-graduate training, experience of terminal care, general life values and attitudes, and experiences of severe illness in the family. The proportion of surgeons, internists, GPs and oncologists who said they would have started CPR was 16, 10, 19 and 14%, respectively. Among physicians aged under 35 years, from 35 to 49 years and over 49 years, the proportions of physicians choosing active CPR were 29, 14 and 13%, respectively (P<0.001). As for those with personal experience of terminal care, 13% indicated they would have started CPR compared with 23% of those who had no experience (P<0.01). Those who made a decision in favour of CPR showed a significantly (P<0.001) more negative attitude to withdrawing life-sustaining treatment and valued length of life to a much greater extent (P<0.01).
