Patients' perceptions of written consent: questionnaire study.

OBJECTIVE: To examine patients' understanding of the status, function, and remit of written consent to surgery. DESIGN: Prospective questionnaire study. Questionnaires were sent to patients within one month of surgery. Responses were analysed with frequencies and single variable analyses. SETTING: Large teaching hospital. PARTICIPANTS: 732 patients who had undergone surgery in obstetrics and gynaecology over a six month period. MAIN OUTCOME MEASURES: Patients' awareness of the legal implications of written consent and their views on the function and remit of the consent form. RESULTS: Patients had limited understanding of the legal standing of written consent. Nearly half (46%, 95% confidence interval 43% to 50%) of patients believed the primary function of consent forms was to protect hospitals and 68% (65% to 71%) thought consent forms allowed doctors to assume control. Only 41% (37% to 44%) of patients believed consent forms made their wishes known. CONCLUSIONS: Many patients seem to have limited awareness of the legal implications of signing or not signing consent forms, and they do not recognise written consent as primarily serving their interests. Current consent procedures seem inadequate as a means for the expression of autonomous choice, and their ethical standing and credibility can be called into question.

Patient refusal of emergency cesarean delivery: a study of obstetricians' attitudes in Europe.

OBJECTIVE: To compare the attitudes of a large sample of obstetricians from eight European countries toward a competent woman's refusal to consent to an emergency cesarean delivery for acute fetal distress. METHODS: Obstetricians' attitudes in response to a hypothetical clinical case were surveyed through an anonymous, self-administered questionnaire. The sample included 1,530 obstetricians (response rate 77%) from 105 maternity units (response rate 70%) in eight countries: France, Germany, Italy, Luxembourg, Netherlands, Spain, Sweden and the United Kingdom. RESULTS: In every country, the majority of obstetricians would keep trying to persuade the woman, telling her that failure to perform cesarean delivery might result in the fetus surviving with disability, or even that her own life might be endangered. In Spain, France, Italy, and, to a lesser extent, Germany and Luxembourg, a consistent proportion of physicians would seek a court order to protect fetal welfare or avoid possible legal liability or both. In the United Kingdom, Sweden, and Netherlands, several respondents (59%, 41%, and 37%, respectively) would accept the woman's decision and assist vaginal delivery. Only a small minority (from 0 in the United Kingdom to 10% in France) would proceed with cesarean delivery without a court order. CONCLUSION: Case law arising from a few countries (United States, Canada, and the United Kingdom) and professional guidelines favoring women's autonomy have not solved the underlying ethical conflict, and in Europe acceptance of a woman's right to refuse cesarean delivery, at least in emergency situations, is not uniform. Differing attitudes between obstetricians from the eight countries may reflect diverse legal and ethical environments. LEVEL OF EVIDENCE: III.

Why do women consent to surgery, even when they do not want to? An interactionist and Bourdieusian analysis.

The 'informed consent' process has been placed at the centre of bioethical and policy discourses about how the autonomy and rights of patients can best be protected. Although there has been critical analysis of how the process functions in relation to participation in research and particular ethical 'dilemmas', there has been little examination of the routine business of consenting to medical procedures. Evidence is now beginning to emerge that people may consent to surgery even when reluctant to do so. In this paper, we develop an analysis informed by Bourdieusian and interactionist social theory of the accounts of 25 British women who consented to surgery in obstetrics and gynaecology. Of these, nine were ambivalent or opposed to having an operation. When faced with a consent form, women's accounts suggest that they rarely do anything other than obey professionals' requests for a signature. Women's capacity to act is reduced as they become enmeshed in the hospital structure of tacit, socially imposed rules of conduct. However, the interactionist account of power operating through the social rules of particular situated encounters, and the sanctions associated with rule-breaking, may not provide a sufficiently powerful explanation for why women submit to surgery they are opposed or ambivalent towards. Bourdieu's concepts of habitus, capital and symbolic power/violence offer a potentially more elaborated account, by showing how the practical logic that women apply in the field of surgery confers a 'sense of place' relative to professionals. Women experience deficits in capital, intensified by their physical vulnerability in critical situations, that severely constrain their ability to exercise choice. This work demonstrates the weakness of the consent process as a safeguard of autonomy. Far from reinforcing autonomy, the process may reinforce rather than disrupt passivity, but more generally our findings raise the question of the extent to which autonomy is an illusory goal.

Factors affecting the outcome of endometrial ablation using Cavaterm plus.

OBJECTIVE: To study treatment outcome using the modified technique: Cavaterm plus. STUDY DESIGN: Retrospective postal questionnaire, in a large teaching hospital. One hundred and twenty-eight women with menorrhagia were treated between February 2001 and April 2003. Data were collected prospectively for the duration of the procedure and alternatives offered. Follow up questionnaire was distributed during November 2003 to assess menstrual status. Multiple binary logistic regression was performed to assess factors influencing success. RESULTS: The mean follow up was 72 weeks, 103 patients (80.5%) completed the questionnaire. In 26 (25.2%) cases, there were one or more important deviations from recommended procedure. Twenty (19.4%) women had procedure-related amenorrhoea, 6 (5.8%) had spotting, 35 (34%) had light, and 26 (25.2%) had moderate bleeding. Eleven (10.7%) had a hysterectomy. The risk of failure was inversely related to age (OR 0.778, 95% CI 0.669-0.905), was higher in women who prior to surgery had longer duration of bleeding (OR 1.29, 95% CI 1.1-1.52), and when recommended selection or operative procedures were not followed (OR 5.056, 95% CI 1.097-23.3). CONCLUSION: Cavaterm plus is associated with high patient satisfaction. The technique remains a good choice for women wishing to avoid hysterectomy, but there is a need to observe determinants of poor outcome.

Randomised comparison of distension media for outpatient hysteroscopy.

OBJECTIVE: To compare saline with and without added lignocaine and carbon dioxide distension for out patient hysteroscopy with regards to patient discomfort and hysteroscopic view. DESIGN: Single blind prospective randomised controlled trial. SETTING: Specialist out patient clinics in a large teaching hospital. POPULATION: Women undergoing out patient hysteroscopy and endometrial biopsy for abnormal uterine bleeding. METHOD: Out patient hysteroscopy using carbon dioxide, saline or saline with lignocaine. MAIN OUTCOME MEASURES: Visual analogue score (VAS) for pain and present pain intensity (PPI) as assessed by patients and the quality of hysteroscopic view as assessed by the operator. RESULTS: Of the 305 women approached, 300 women were randomised into the study. The mean [SD] VAS for pain in the carbon dioxide group was 2.9 [2.3] and in the saline group was 3.1 [2.6], the difference was not statistically significant (P= 0.49). The mean [SD] VAS for pain in the saline plus lignocaine group was 3.2 [2.4]. This was not significantly different from the saline group (P= 0.72). There was a statistically significant difference between the confidence rating for the hysteroscopic view for the carbon dioxide compared with the saline group; mean [SD] was 8.3 [2.1] and 9.6 [1.1], respectively (P= 0.001). CONCLUSION: Carbon dioxide and saline as distension media are comparable in terms of overall patient discomfort and satisfaction, but saline provides better views and increases confidence in diagnosis. Adding lignocaine to the saline distension medium does not confer any additional benefit.

Informed consent for elective and emergency surgery: questionnaire study.

OBJECTIVES: To evaluate women's experience of giving consent to obstetric and gynaecological surgery and to examine differences between those undergoing elective and emergency procedures. DESIGN: A prospective questionnaire study. SETTING: A large teaching hospital. POPULATION: 1006 consecutive patients undergoing elective or emergency surgery in obstetrics and gynaecology. METHODS: Questionnaires were administered to women who had given consent to surgery following the introduction of national guidelines and consent form. Differences in responses between elective and emergency patients were assessed using frequencies, single and multivariable analyses. MAIN OUTCOME MEASURES: Patients' experience and recall of the consent process, their overall satisfaction and their views on what is important for adequate consent. RESULTS: There were significant differences between patients undergoing elective or emergency surgery. Patients undergoing emergency surgery were less likely to have read (OR 0.22) or understood (OR 0.40) the consent form, and were more likely to report feeling frightened by signing it (OR 2.52). They were more likely to report they felt they had no choice about signing the consent form (OR 2.11), and that they would have signed regardless of its content (OR 3.14). Overall, significantly more patients undergoing elective (80%) or emergency (63%) surgery reported satisfaction with the consent process. Patients were more likely to report satisfaction if they read (OR 1.80) and agreed with (OR 3.49) the consent form, and if someone checked that they understood (OR 3.09). CONCLUSION: Patients' needs may not be adequately addressed by current guidelines for consent to treatment, particularly in emergency circumstances. The introduction of more complex forms and procedures appears to conflict with patients' need for personal communication and advocacy. The implications on the ethical and legal standing of consent are considerable.

The long-term effectiveness of endometrial laser ablation: a survival analysis.

OBJECTIVES: To assess the long-term effectiveness of endometrial laser ablation and factors that predict long-term outcome. SETTING: A university teaching hospital. STUDY DESIGN: Postal questionnaires were sent to all women who underwent endometrial laser ablation between 1992 and 1998. RESULTS: Of 215 patients who underwent endometrial laser ablation, 174 (80.9%) returned the questionnaire. Duration of follow-up was 1.5-9 years. The procedure was reported as a success by 138 (79.3%) and a failure by 36 (20.7%). Twenty-four patients (13.8%) subsequently underwent hysterectomy for excessive bleeding. Using survival curve estimates the percentage that remained free of failure was 95.3% at 1 year and 76.2% at 4 years. Increasing patient age was significantly associated with reduced risk of failure (hazard ratio 0.91 for every year increase in age). An inexperienced operator significantly increased the hazard of failure. CONCLUSION: Endometrial laser ablation is effective in the long-term in the majority (76.2%) of patients. Older women can expect to have a lower risk of failure.

The inter-role confidentiality conflict in recruitment for clinical research.

Recruiting patients into clinical research is essential for the advancement of medical knowledge. However, when the physician undertaking the care of the patient is also responsible for recruitment into clinical research, a situation arises of an inter-role breach of confidentiality which is distinguishable from other conflicts of interest. Such discord arises as the physician utilizes confidential information obtained within the therapeutic relationship beyond its primary objective, and safeguards ought to be observed in order to avert this important, and generally overlooked, problem. The moral worth of the pledge of confidentiality is based not on its innate value but on its being a promise on which subsequent interactions and disclosures are founded. Within the patient-doctor interaction, confidentiality is an important facet of the promised fidelity and, as such, a loose interpretation of the notion threatens the essence of the relationship, and any violation thereof requires compelling moral justification. To avoid conflict, patients' confidential information ought not be used for the purpose of recruitment, which needs to be undertaken through general education and non-directed appeals, and a preliminary consent to be approached for research should be obtained from the patient prior to her being identified as a suitable research subject. Securing this prior consent would avoid one source of potential, albeit unintended, coercion.
