Attitudinal factors associated with community pharmacists' involvement in services for drug misusers.
AIM: To assess the relationship between pharmacists' attitudes towards drug misusers and the availability and provision of services for drug misusers. DESIGN: A cross-sectional postal questionnaire survey. SETTING: All community pharmacies in Scotland (n = 1142). PARTICIPANTS: A total of 864 pharmacists managing community pharmacies on a day-to-day basis (response rate 79%). MEASUREMENTS: Descriptive data were collected on demography, drug misuse services provided and training in drug misuse. Attitude statements were used to measure attitudes to drug misusers, the role of the pharmacist in dispensing controlled drugs and providing injecting equipment, providing advice on drug misuse and financial aspects of service provision. Statements were incorporated into a scale which was correlated with behavioural data on whether and how services were provided. RESULTS: The attitude scale had good internal reliability and was unidimensional. Pharmacists that provided needle/syringe exchanges, sold needles/syringes, dispensed methadone, supervised the consumption of methadone and provided health promotion services to drug misusers had significantly more positive attitudes towards drug misusers. Attitudes were associated with health board area, sex and number of years registered as a pharmacist. After controlling for these characteristics, attitude was an independent predictor of whether needles/syringes were sold, methadone was dispensed and methadone consumption supervised. CONCLUSIONS: Addressing negative attitudes could encourage more pharmacists to provide services and enhance the process of service delivery.

Admission-discharge policies for hysteroscopic surgery: a randomised comparison of day case with in-patient admission.
OBJECTIVE: To study the effectiveness and acceptability of day case hysteroscopic surgery. DESIGN: Prospective randomised controlled trial. SETTING: Aberdeen Royal Infirmary. SUBJECTS: One hundred and ninety four consecutive women who underwent hysteroscopic endometrial ablation. INTERVENTION: Seventy three women were allocated to day case surgery and 37 to inpatient admission; 84 women though otherwise fit for day case surgery were scheduled for in-patient admission as they lived more than 20 miles away. All women completed a questionnaire 24 h after their operations. Readmission rates were obtained from case notes. Satisfaction rates 12 months after the operation were recorded by means of a follow-up questionnaire. RESULTS: Post-operative pain was absent or slight in 48 (75%) of the women in the day case group 27 (84%) of women in the in-patient group, and 55 (82%) in the non-randomised in-patient group. Post-operative analgesia was necessary in 34 (52%) women in the day case group, 24 (75%) women in the in-patient group and 36 (53%) women in the non-randomised in-patient group. Hospital costs were significantly less in the day case group. Satisfaction with stay 92% in the day case group, and 100% in the other two groups. CONCLUSION: In this setting, day care is a safe acceptable and less expensive alternative to in-patient care for hysteroscopic endometrial ablation.

A randomised controlled trial of two pressure-reducing surfaces.
This randomised controlled trial of two dry-flotation pressure-reducing surfaces evaluates pressure sore incidence, patient comfort and the appropriate use of equipment in 100 orthopaedic patients. The trial involved five full Roho mattresses, five Sofflex mattresses and 10 Roho Quatro cushions to be used to complement the beds. Given the low rate of pressure sore incidence in this high-risk group it is not possible to determine whether there is any difference in effectiveness between the two mattresses. Both appear to provide similar levels of comfort, with the majority of patients finding them either comfortable or very comfortable. The initial setting of the equipment was, however, unsatisfactory.

Satisfaction and the three C's: continuity, choice and control. Women's views from a randomised controlled trial of midwife-led care.
OBJECTIVE: 1. To explore whether there are differences in women's satisfaction with care in a midwife-managed delivery unit compared with that in a consultant-led labour ward. 2. To compare factors relating to continuity, choice and control between the two randomised groups. DESIGN: A pragmatic randomised controlled trial. SETTING: Aberdeen Maternity Hospital, Grampian. SAMPLE: 2844 women, identified at booking as low risk, were randomised in a 2:1 ratio between the midwives' unit and the labour ward. MAIN OUTCOME MEASURES: Satisfaction, continuity of carer, choice, and control. RESULTS: Satisfaction with the overall experience did not differ between the groups. Satisfaction with how labour and delivery was managed by staff was slightly higher in the midwives' unit group, but this did not reach the 0.1% level of significance. Women allocated to the midwives' unit group saw significantly fewer medical staff and were less likely to report numerous individuals entering the room. They were more likely to report having had a choice regarding mobility and alternative positions for delivery and were significantly more likely to have made their own decisions regarding pain relief. CONCLUSIONS: The issues surrounding the measurement of satisfaction with childbirth need further investigation. Until this area is clarified it would be unwise to use an overall measure of satisfaction as an indicator of the quality of maternity service provision. In particular, the current measures are not sensitive enough to examine the specific factors which affect women's satisfaction. Further research is required to assess which factors are important to women if they are to have a positive experience of childbirth and how these priorities change over time.

A pragmatic randomised comparison of transcervical resection of the endometrium with endometrial laser ablation for the treatment of menorrhagia.
OBJECTIVE: To compare endometrial laser ablation (ELA) with transcervical resection of the endometrium (TCRE) in the treatment of menorrhagia. DESIGN: Randomised controlled trial. SETTING: Gynaecology department of a large teaching hospital. PARTICIPANTS: Women with menorrhagia due to dysfunctional uterine bleeding (n = 372) were randomly allocated to ELA (n = 188) or TCRE (n = 184). MAIN OUTCOME MEASURES: Operative complications, post-operative recovery, relief of menstrual and other symptoms, need for further surgical treatment, satisfaction with treatment after 6 and 12 months, and differential resource use. RESULTS: TCRE was significantly quicker, with lower rates of fluid overload. Perioperative morbidity was low and similar in both groups. Outcome at 12 months was also similar: 72 women (45%) had either amenorrhoea or brown discharge in the ELA group compared with 71 (49%) in the TCRE group; 79 (49%) versus 68 (46%) had lighter periods. Thirty (16%) versus 36 (20%) had received further surgical treatment: 9 (5%) compared with 25 (14%) had had a hysterectomy and 21 (11%) versus 11 (6%) had received repeat ablation. Anxiety and depression, dysmenorrhoea and pre-menstrual symptoms were improved by both procedures and bladder symptoms were affected by neither. At 12 months 148 (90%) women in the ELA group and 140 (91%) women in the TCRE group were satisfied with their treatment. The estimated additional cost of ELA was Pound 145 per procedure. CONCLUSIONS: At one year there was no clear difference in clinical outcome between ELA and TCRE. Both procedures were associated with low morbidity. ELA was the more costly procedure. Despite the need for further surgery for about one in six women, satisfaction rates were high following both ELA and TCRE.

Randomised trial comparing hysterectomy with endometrial ablation for dysfunctional uterine bleeding: psychiatric and psychosocial aspects.
OBJECTIVE: To compare in psychiatric and psychosocial terms the outcome of hysterectomy and endometrial ablation for the treatment of dysfunctional uterine bleeding. DESIGN: Prospective randomised controlled trial. SETTING--Obstetrics and gynaecology department of a large teaching hospital. SUBJECTS: 204 women with dysfunctional bleeding for whom hysterectomy would have been the preferred treatment were recruited over 24 months and randomly allocated to hysterectomy (99 women) or to hysteroscopic surgery (transcervical resection (52 women) or laser ablation (53 women). MAIN OUTCOME MEASURES: Mental state, martial relationship, psychosocial and sexual adjustment in assessments conducted before the operation and one month, six months, and 12 months later. RESULTS: Both treatments significantly reduced the anxiety and depression present before the operation, and there were no differences in mental health between the groups at 12 months. Hysterectomy did not lead to postoperative psychiatric illness. Sexual interest after the operation did not vary with treatment. Overall, 46 out of 185 (25%) women reported a loss sexual interest and 50 out of 185 (27%) reported increased sexual interest. Marital relationships were unaffected by surgery. Personality and duration of dysfunctional uterine bleeding played no significant part in determining outcome. CONCLUSIONS: Hysteroscopic surgery and hysterectomy have a similar effect on psychiatric and psychosocial outcomes. There is no evidence that hysterectomy leads to postoperative psychiatric illness.

A cost comparison of hysterectomy and hysteroscopic surgery for the treatment of menorrhagia.
OBJECTIVES: To estimate and compare the costs of treating women with menorrhagia by hysterectomy or hysteroscopic surgery, in the form of transcervical resection of the endometrium (TCRE) or endometrial laser ablation (ELA). STUDY DESIGN: Randomised controlled trial set in the gynaecological department of a large British teaching hospital. Under usual circumstances, 204 women who would have undergone hysterectomy for menorrhagia were randomly allocated to either hysterectomy (n = 99) or hysteroscopic surgery in the form of TCRE (n = 52) or ELA (n = 53). National Health Service (NHS) costs and costs to patients per patient occurring up to 1 year following surgery were estimated. Theatre times and length of hospital stay were recorded during the trial. Costs were obtained from the health board finance department and relevant suppliers of technical equipment. One year after treatment patients completed questionnaires on personal costs incurred. RESULTS: The NHS costs of treating women with hysteroscopic surgery were 24% (TCRE) or 20% (ELA) less than treating women by hysterectomy (1001 pounds/1046 pounds vs. 1315 pounds). On average, women undergoing hysteroscopic surgery incurred 71% less costs to themselves than those who underwent hysterectomy (21 pounds vs. 73.40 pounds). CONCLUSIONS: Hysteroscopic endometrial ablation incurs less costs than hysterectomy both to the National Health Service and to women alike, up to 1 year after surgery.

A comparison of bladder and ovarian function two years following hysterectomy or endometrial ablation.
OBJECTIVE: To test the hypothesis that at two years bladder and ovarian function function are no different following either simple hysterectomy or endometrial ablation (transcervical resection/laser ablation). DESIGN: Randomised controlled trial comparing hysterectomy with endometrial ablation. Two years after trial entry bladder and ovarian function were evaluated subjectively by means of questionnaires and objectively by means of cystometry and estimation of serum follicle stimulating hormone respectively. SETTING: Aberdeen Royal Infirmary. PARTICIPANTS: Tow hundred and four women with dysfunctional uterine bleeding who, when recruited to the initial study two years previously, were aged less than 50 years, weighed less than 100 kg, and who would otherwise have undergone hysterectomy. RESULTS: Of the 204 women originally recruited, 101 re-attended the clinic and underwent cystometry and follicle stimulating hormone estimation. These, together with a further 59 women, completed postal questionnaires (79% of original cohort). Rates of stress incontinence (44% vs 44%, 95% CI of difference -16% to +15%), urge incontinence (21% vs 19% 95% CI of difference -11% to +14%), and hot flushes (30% vs 44%, 95% CI of difference -25% to +7%) were similar in the hysterectomy and endometrial ablation groups, respectively. Cystometry revealed 14 (31%) cases of bladder dysfunction after hysterectomy and 17 (35%) after hysteroscopic surgery (95% CI of difference -23% to +15%). Serum follicle stimulating hormone levels > 40 IU/L [corrected] were found in three (6%) women following hysterectomy and five (10%) of women after endometrial ablation. CONCLUSION: This study suggests that in comparison with endometrial ablation, simple hysterectomy for dysfunctional uterine bleeding does not compromise bladder or ovarian function, at least at two years after the operation. Due to lack of power the estimates of any differences are imprecise, and clinically significant effects cannot be ruled out.

Antenatal screening for carriers of cystic fibrosis: randomised trial of stepwise v couple screening.
OBJECTIVE: To perform a rigorous comparative evaluation of stepwise and couple approaches to antenatal carrier screening for cystic fibrosis. DESIGN: Pragmatic randomised trial. SETTING: Hospital antenatal clinic serving a regional population. SUBJECTS: 2002 women (couples) attending for booking antenatal visit at less than 17 weeks' gestation with no family history of cystic fibrosis. INTERVENTIONS: Offering counselling and carrier testing for cystic fibrosis, either to women in the first instance (stepwise) or to couples (couple screening). MAIN OUTCOME MEASURES: Uptake rates; anxiety; knowledge of cystic fibrosis and carrier status (both partners); attitudes to health, pregnancy, the baby, and screening (both partners); and uptake of carrier testing by relatives. RESULTS: Uptake of screening was the same for both approaches (90%). After delivery most women remembered test results and their meaning, but 53/253 (21%) of those with negative results of couple testing had forgotten that repeat testing would be advisable if they had a pregnancy with a new partner. With stepwise screening women identified as carriers had high levels of anxiety when results were received (mean anxiety score 52.3). This dissipated with a reassuring partner's result (carriers' mean anxiety score 36.1) to levels similar to those receiving negative results from couple screening. Of those receiving negative results, women who had stepwise screening were significantly less anxious than those who had couple screening (mean score with result 32.1 v 35.4, 95% confidence interval for difference -4.7 to -2.1). CONCLUSIONS: Couple screening allows carriers to avoid transient high levels of anxiety, but is associated with more anxiety and false reassurance among most screenees who will test negative. Stepwise screening gives carriers and their relatives genetic information and is, in our opinion, the better method.

Satisfaction and continuity of care: staff views of care in a midwife-managed delivery unit.
OBJECTIVE: to examine whether there are differences in the midwife's role in, and satisfaction with, intrapartum care and delivery of women at low obstetric risk in a midwife-managed delivery unit compared to a consultant-led labour ward. DESIGN: a pragmatic randomised controlled trial. Subjects were randomised in a 2:1 ratio between the midwives' unit and the labour ward. SETTING: Aberdeen Maternity Hospital, Grampian, UK. SUBJECTS: midwives within the delivery suite who cared for the 2844 women at low obstetric risk receiving care in a pragmatic randomised controlled trial of the two delivery areas. PRIMARY OUTCOME MEASURES: continuity of carer and midwife satisfaction. FINDINGS: midwives looking after women in the midwives' unit group were significantly more likely to be of a higher grade, more qualified and have a longer length of experience than those in the labour ward group. There was greater continuity of carer both during labour and after delivery in the midwives' unit group. Despite a small but statistically significant difference in overall satisfaction between the groups, area of 'booking' or area of delivery were not important in predicting midwife satisfaction. Autonomy and continuity of carer were the best predictors of midwife satisfaction. CONCLUSIONS: midwife-managed intrapartum care increases continuity of carer and, therefore, midwife satisfaction. Extending this outside the delivery suite requires a system of care that is acceptable to midwives as well as women. Such systems will depend to a large extent on geography, consumer demand and availability of resources. However, midwife satisfaction should also be considered. In order to do this further research is required to fully evaluate the effect these systems have on the midwives working in them.

Costs of intrapartum care in a midwife-managed delivery unit and a consultant-led labour ward.
OBJECTIVE: to investigate whether there are differences between the cost of intrapartum care for women at low obstetric risk in a midwife-managed labour and delivery unit and that in a consultant-led labour and delivery ward. DESIGN: cost analysis based on the findings of a randomised controlled trial comparing two alternative types of intrapartum care. SETTING: Aberdeen Maternity Hospital, Grampian. SUBJECTS: the number of women 'booked' for care in the Midwives' Unit in a standard year and a comparable group of women cared for in the consultant-led labour ward. PRIMARY OUTCOME MEASURE: the cost 'outcome' is the extra (or reduced) cost per woman resulting from the introduction of a midwife-managed delivery unit. FINDINGS: the baseline extra cost of the introduction of the Midwives' Unit was found to be 40.71 pounds per woman. Depending on the scenario used, this ranged from a cost saving of 9.74 pounds per woman to an additional cost of 44.23 pounds per woman. CONCLUSIONS: this study has shown that, in terms of costs incurred during the intrapartum period, the marginal cost of caring for women at low obstetric risk alongside women at high obstetric risk in a standard labour ward is small. However, the impact of establishing a separate midwife-managed delivery unit, requiring an increase in midwifery staffing levels, can be significant.

A prospective randomised study of the effects of prophylactic antibiotics on the incidence of bacteraemia following hysteroscopic surgery.
OBJECTIVE: To study the effect of prophylactic antibiotics on the incidence of bacteraemia following hysteroscopic surgery. DESIGN: Prospective randomized study. SETTING: Aberdeen Royal Infirmary. SUBJECTS: One hundred and sixteen women about to undergo either endometrial laser ablation (ELA) or transcervical resection of the endometrium (TCRE). INTERVENTION: Fifty-five women were randomised to receive 1.2 g of Augmentin (co-amoxiclav) i.v. at induction of anaesthesia. Sixty-one women received no antibiotic prophylaxis. Blood cultures were obtained at the end of the surgical procedure. RESULTS: Incidence of bacteraemia in the non-antibiotic group (16%) was significantly higher than that in the antibiotic group (2%) (95% confidence interval for difference from 5% to 25%). The majority of organisms were of dubious clinical significance and contamination could not be excluded in 7 cases out of 10. CONCLUSION: There is no convincing evidence that antibiotics are of value in this clinical setting.

Midwife managed delivery unit: a randomised controlled comparison with consultant led care.
OBJECTIVE: To examine whether intrapartum care and delivery of low risk women in a midwife managed delivery unit differs from that in a consultant led labour ward. DESIGN: Pragmatic randomised controlled trial. Subjects were randomised in a 2:1 ratio between the midwives unit and the labour ward. SETTING: Aberdeen Maternity Hospital, Grampian. SUBJECTS: 2844 low risk women, as defined by existing booking criteria for general practitioner units in Grampian. 1900 women were randomised to the midwives unit and 944 to the labour ward. MAIN OUTCOME MEASURES: Maternal and perinatal morbidity. RESULTS: Of the women randomised to the midwives unit, 647 (34%) were transferred to the labour ward antepartum, 303 (16%) were transferred intrapartum, and 80 (4%) were lost to follow up. 870 women (46%) were delivered in the midwives unit. Primigravid women (255/596, 43%) were significantly more likely to be transferred intrapartum than multi-gravid women (48/577, 8%). Significant differences between the midwives unit and labour ward were found in monitoring, fetal distress, analgesia, mobility, and use of episiotomy. There were no significant differences in mode of delivery or fetal outcome. CONCLUSIONS: Midwife managed intrapartum care for low risk women results in more mobility and less intervention with no increase in neonatal morbidity. However, the high rate of transfer shows that antenatal criteria are unable to determine who will remain at low risk throughout pregnancy and labour.

Prediction of recurrent bleeding after endoscopic haemostasis in non-variceal upper gastrointestinal haemorrhage.
Endoscopic haemostasis by injection of adrenaline was attempted in 135 consecutive patients with active upper gastrointestinal bleeding. Initial haemostasis was obtained in 127 patients following injection of 5-15 ml 1:10,000 adrenaline; eight patients in whom haemostasis was not achieved underwent immediate laparotomy. There was further haemorrhage in 25 patients, which was successfully treated by further injection of adrenaline in ten. Fifteen patients had major rebleeding requiring emergency surgery. Stepwise logistic regression analysis identified three factors that, taken together, were highly predictive of the need for surgery: pulse rate on admission, the position of the ulcer and whether the patient was obese. A scoring system was derived from the logistic analysis equation that was found to predict correctly the need for emergency surgery in 84 per cent of patients. In patients with a high probability of rebleeding surgery should be considered after initial endoscopic haemostasis and stabilization. In the majority of patients endoscopic treatment alone is sufficient for permanent haemostasis.

Preimplantation diagnosis or chorionic villus biopsy? Women's attitudes and preferences.
The objective of this work was to assess women's attitudes and preferences to two methods of prenatal diagnosis for genetic disease: embryo and chorionic villus biopsy (CVS). The design involved a structured postal questionnaire sent to women in the Grampian region with different reproductive experiences. The population sample included 46 women who had had genetic counselling because of a family history of a single gene disorder, 18 women who had had CVS for a single gene disorder, 158 women who had had CVS for other reasons, 200 women who had recently delivered a normal baby and 50 women who had experience of in-vitro fertilization (IVF). The main outcome measures were attitudes to family limitation, prenatal diagnosis, termination for fetal abnormality, embryo biopsy and CVS. Of the women surveyed, 38% preferred embryo diagnosis, whereas 42% favoured CVS and termination. Women with previous experience of CVS preferred this option whereas those with experience of IVF as infertility treatment were more likely to favour embryo diagnosis, as were women who had had genetic counselling for a single gene disorder. It was concluded that a substantial number of women find embryo diagnosis more acceptable than CVS when the pregnancy is at high risk. This is especially true amongst those with experience of IVF or who are at risk themselves. A demand for embryo diagnosis has been demonstrated.
