Pilot study: quality of life assessment of postnatal fatigue and other physical morbidity.

Postnatal morbidity is increasingly recognized, but standard assessments may not capture what is most important to the woman with such morbidity in terms of her quality of life. The Mother-Generated Index (MGI) is a proposed postnatal quality-of-life instrument which allows the mother to determine both content and scoring. In this pilot study we found that although a degree of psychological and physical morbidity (including tiredness) is common, and may be very significant, for most women these factors are low-grade, and other aspects of their lives are more important. A quality-of-life approach allows the mother to determine her own postnatal assessment, and encourages practitioners to view her more holistically.

Urodynamic investigations for management of urinary incontinence in adults.

BACKGROUND: Urodynamic tests are used to investigate people who have urinary incontinence or other urinary symptoms in order to make a definitive objective diagnosis. The aim is to help to select the treatment most likely to be successful. The investigations are invasive and time consuming. OBJECTIVES: The objective of this review was to discover if treatment according to a urodynamic-based diagnosis led to clinical improvements in urinary incontinence, compared to treatment based on history and examination. SEARCH STRATEGY: We searched the Cochrane Incontinence Group trials register. Date of the most recent search: April 2002. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing clinical outcomes in groups of people who were and were not investigated using urodynamics, or comparing one type of urodynamics against another. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Authors of one study were contacted for more information, including adverse effects. MAIN RESULTS: Two small trials involving 128 women were included. In one small trial, women who were investigated with urodynamics were more likely to receive active treatment with drugs or surgery. However, the numbers in both trials were too small to determine if this affected clinical outcomes such as a reduction in incontinence. REVIEWER'S CONCLUSIONS: A larger definitive trial is needed, in which people are randomly allocated to management according to urodynamic findings or to standard management based on history and clinical examination.

Bladder neck needle suspension for urinary incontinence in women.

BACKGROUND: Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of them have moderate or severe symptoms. OBJECTIVES: To determine the effects of needle suspension on stress or mixed urinary incontinence in comparison with other management options. SEARCH STRATEGY: We searched the Cochrane Incontinence Group specialised register and reference lists of relevant articles. Date of last search: December 2001. SELECTION CRITERIA: Randomised or quasi-randomised trials that included needle suspension for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: Trials were assessed and data extracted independently by at least two reviewers. One trial investigator was contacted for additional information. MAIN RESULTS: Eight trials were identified which included 327 women having six different types of needle suspension procedures and 407 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension (higher subjective failure rate after the first year (70/267, 26% failed vs 33/243, 14% failed after open abdominal retropubic suspension: RR 2.10, 95% CI 1.45 to 3.04) and there were more peri-operative complications (36/75, 48% vs 23/77, 30%; RR 1.51, 95% CI 1.06 to 2.15), but there were no significant differences for other outcome measures. This effect was confined to women with primary incontinence: too few women with recurrent incontinence were studied to draw conclusions about the effects of secondary operations. Needle suspensions may be as effective as anterior vaginal repair (46/128, 36% failed after needles vs 50/129, 39% after anterior repair; RR 0.93, 95% CI 0.68 to 1.26) but there was little information about morbidity. Data for comparison with suburethral slings were inconclusive because they came from a small and atypical population. No trials compared needle suspensions with conservative management, peri-urethral injections or sham or laparoscopic surgery. REVIEWER'S CONCLUSIONS: Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary genuine stress urinary incontinence in terms of lower cure rates and higher morbidity. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on secondary procedures or on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity.

Simple behavioural and physical interventions for nocturnal enuresis in children.

BACKGROUND: Nocturnal enuresis (bedwetting) is a socially disruptive and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs can be great. Simple behavioural methods of treating bedwetting include reward systems such as star charts given for dry nights, lifting or waking the children at night to urinate, retention control training to enlarge bladder capacity (bladder training) and fluid restriction. OBJECTIVES: To assess the effects of simple behavioural interventions on nocturnal enuresis in children, and to compare these with other interventions. SEARCH STRATEGY: We searched the Cochrane Incontinence Group trials register. The reference list of a previous version of this review was also searched. Date of the most recent search: December 2001. SELECTION CRITERIA: All randomised or quasi-randomised trials of simple behavioural interventions for nocturnal enuresis in children up to the age of 16. Trials focused solely on daytime wetting were excluded. DATA COLLECTION AND ANALYSIS: In a previous version of this review, trials up to 1997 were independently assessed by two reviewers. Previous trials were re-assessed, and further trials were assessed for quality, and data were extracted by another reviewer. MAIN RESULTS: Twelve reliable trials met the inclusion criteria, involving 748 children of whom 365 received a simple behavioural intervention. However, within each comparison each outcome was addressed by single trials only, precluding meta-analysis. In single small trials, reward systems (e.g. star charts), lifting and waking were each associated with significantly fewer wet nights, higher cure rates and lower relapse rates compared to controls. There was not enough evidence to evaluate retention control training (bladder training), whether compared with controls or dry bed training, or used as a supplement to alarms, or versus desmopressin. Cognitive therapy may have lower failure and relapse rates than star charts, but this finding was based on one small trial only. One small trial of poor quality suggested that star charts were initially less successful than amitriptyline but this difference did not persist after the treatments stopped. REVIEWER'S CONCLUSIONS: Simple behavioural methods may be effective for some children, but further trials are needed, in particular in comparison with treatments known to be effective, such as desmopressin, tricyclic drugs and alarms. However, simple methods could be tried as first line therapy before considering alarms or drugs, because these alternative treatments may be more demanding and may have adverse effects.

Conservative management of persistent postnatal urinary and faecal incontinence: randomised controlled trial.

OBJECTIVES: To assess the effect of nurse assessment with reinforcement of pelvic floor muscle training exercises and bladder training compared with standard management among women with persistent incontinence three months postnatally. DESIGN: Randomised controlled trial with nine months' follow up. SETTING: Community intervention in three centres (Dunedin, New Zealand; Birmingham; Aberdeen). PARTICIPANTS: 747 women with urinary incontinence three months postnatally, allocated at random to intervention (371) or control (376) groups. INTERVENTION: Assessment by nurses of urinary incontinence with conservative advice on pelvic floor exercises at five, seven, and nine months after delivery supplemented with bladder training if appropriate at seven and nine months. MAIN OUTCOME MEASURES: Primary: persistence and severity of urinary incontinence 12 months after delivery. Secondary: performance of pelvic floor exercises, change in coexisting faecal incontinence, wellbeing, anxiety, and depression. RESULTS: Women in the intervention group had significantly less urinary incontinence: 167/279 (59.9%) v 169/245 (69.0%), difference 9.1% (95% confidence interval 1.0% to 17.3%, P=0.037) for any incontinence and 55/279 (19.7%) v 78/245 (31.8%), difference 12.1% (4.7% to 19.6%, P=0.002) for severe incontinence. Faecal incontinence was also less common: 12/273 (4.4%) v 25/237 (10.5%), difference 6.1% (1.6% to 10.8%, P=0.012). At 12 months women in the intervention group were more likely to be performing pelvic floor exercises (218/278 (79%) v 118/244 (48%), P<0.001). CONCLUSIONS: A third of women may have some urinary incontinence three months after childbirth. Conservative management provided by nurses seems to reduce the likelihood of urinary and coexisting faecal incontinence persisting 12 months postpartum. Further trials for faecal incontinence are needed.

Alarm interventions for nocturnal enuresis in children.

BACKGROUND: Enuresis (bedwetting) is a socially disruptive and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. OBJECTIVES: To assess the effects of alarm interventions on nocturnal enuresis in children, and to compare alarms with other interventions. SEARCH STRATEGY: The following electronic databases were searched: MEDLINE to June 1997; AMED; ASSIA; BIDS; BIOSIS Previews (1985-1996); CINAHL; DHSS Data; EMBASE (1974 to June 1997); PsycLIT and SIGLE. Organisations, manufacturers, researchers and health professionals concerned with enuresis were contacted for information. The reference sections of obtained studies were also checked for further trials. Date of the most recent search: July 1997. SELECTION CRITERIA: All randomised trials of alarm interventions for nocturnal enuresis in children were included in the review. Trials were eligible for inclusion if: children were randomised to alarm treatment compared with controls, other behavioural methods or drugs for nocturnal bedwetting; participants with organic causes for their bedwetting were excluded; and baseline assessments of the level of bedwetting were reported. Trials focused solely on daytime wetting were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the quality of the eligible trials, and extracted data. MAIN RESULTS: Twenty two randomised trials met the inclusion criteria, involving 1125 children who received treatment with alarms. The quality of many of the trials was poor, and many comparisons were addressed only by single trials. Children treated with alarms were significantly more likely than untreated controls to become dry during treatment (RR for failing to achieve 14 dry nights 0.27, 95% CI 0.19 to 0.39) and failing to remain dry (RR 0.58, 95%CI 0.46 to 0.74). There was insufficient evidence to judge whether one type of alarm is better than another and whether alarms alone were as good as or better than other behavioural interventions alone or as a supplement to alarm treatment. Desmopressin or tricyclics seem as effective as alarms while on treatment. There was limited evidence to suggest that the relapse rate might be lower after stopping alarm treatment than after desmopressin (RR 0.11, 95% CI 0.02 to 0.78). REVIEWER'S CONCLUSIONS: Alarm interventions are an effective treatment for nocturnal bedwetting in children. Desmopressin and tricyclics appeared as effective while on treatment, but this effect was not sustained after treatment stopped, and alarms may be more effective in the long term. Comparisons between drug and behavioural treatments are needed, and should include relapse rates after treatment is finished.

Obstetric practice and faecal incontinence three months after delivery.

OBJECTIVE: To determine whether obstetric and maternal factors relate to faecal incontinence at three months postpartum. SETTING: Maternity units in Aberdeen (Scotland), Birmingham (England) and Dunedin (New Zealand). POPULATION: All women who delivered during one year in the three maternity units. METHODS: Postal questionnaire at three months postpartum, to obtain information on faecal incontinence, linked to obstetric casenote data. MAIN OUTCOME MEASURES: Prevalence of faecal incontinence. RESULTS: 7879 questionnaires were returned, a 71.7% response rate. The prevalence of faecal incontinence was 9.6%, with 4.2% reporting this more often than rarely. Logistic regression, confined to primiparae, showed that forceps delivery was a predictor of an increased risk of symptoms (OR = 1.94, 95% CI 1.30 to 2.89) while vacuum extraction was not associated. Caesarean section was marginally associated with a reduced risk (OR = 0.58, 95% CI 0.35 to 0.97). Older maternal age, Indian sub-continent ethnic origin and body mass index 'not known' also showed significant associations. No associations were found for induced labour, duration of second stage labour, episiotomy, laceration or birthweight. CONCLUSIONS: Women delivered by forceps had almost twice the risk of developing faecal incontinence, whereas vacuum extraction was not associated with faecal incontinence at three months postpartum. Caesarean section appears to offer some protection.

Elective versus selective caesarean section for delivery of the small baby.

BACKGROUND: Elective caesarean delivery for women in preterm labour might reduce the chances of fetal or neonatal death, but it might also increase the risk of maternal morbidity. OBJECTIVES: The objective of this review was to assess the effects of a policy of elective caesarean delivery versus selective caesarean delivery for women in preterm labour. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group trials register was searched. SELECTION CRITERIA: Randomised trials comparing a policy of elective caesarean delivery with expectant management with recourse to caesarean section. DATA COLLECTION AND ANALYSIS: One reviewer assessed eligibility and trial quality. MAIN RESULTS: Five studies involving 104 women were included. All trials reported recruiting difficulties. No significant differences between elective and selective policies for caesarean delivery were found for fetal, neonatal or maternal outcomes. REVIEWER'S CONCLUSIONS: There is not enough evidence to evaluate the use of a policy for elective caesarean delivery for small babies. Randomised trials in this area are likely to continue to experience recruitment problems. However it still may be possible to investigate elective caesarean delivery in preterm babies presenting cephalically.

Anterior vaginal repair for urinary incontinence in women.

BACKGROUND: Anterior vaginal repair (anterior colporrhaphy) is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience urinary incontinence. OBJECTIVES: To determine the effects of anterior vaginal repair (anterior colporrhaphy) on stress or mixed urinary incontinence in comparison with other management options. SEARCH STRATEGY: We searched the Cochrane Incontinence Group's trials register, and the reference lists of relevant articles. Date of most recent search: March 1999. SELECTION CRITERIA: Randomised or quasi-randomised trials that included anterior vaginal repair for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: Both reviewers independently extracted data and assessed trial quality. One trial investigator was contacted for additional information. MAIN RESULTS: Five trials were identified which included 208 women having an anterior vaginal repair and 400 who received comparison interventions. A single small trial provided insufficient evidence to assess anterior repair in comparison with physical therapy. The performance of anterior repair in comparison with needle suspension appeared similar but clinically important differences could not be confidently ruled out. No trials compared anterior repair with sling or laparoscopic interventions, or compared alternative vaginal operations. Anterior repair was less effective than abdominal retropubic suspension based on patient-reported cure rates in four trials both in the short-term (failure rate within first year after anterior repair 48/198, 24% vs 30/266, 11%; RR 2.15, 95% CI 1.4 to 3.28) and long-term (80/193, 41% vs 51/261, 20%; RR 2.25, 95% CI 1.66 to 3.04). There was some evidence from one of these trials that this was reflected in fewer repeat operations for incontinence. These findings held irrespective of the co-existence of prolapse (pelvic relaxation). Although later prolapse operation appeared to be equally common after vaginal or abdominal operation there were too few data to judge this reliably. In respect of the type of abdominal retropubic suspension, most data related to comparisons of anterior repair with Burch colposuspension. The few data describing comparison of anterior repair with the Marshall-Marchetti-Krantz procedure were consistent with those for Burch colposuspension. REVIEWER'S CONCLUSIONS: There were not enough data to allow comparison of anterior vaginal repair with physical therapy or needle suspension for primary urinary stress incontinence in women. Abdominal retropubic suspension appeared to be better than anterior vaginal repair judged on subjective cure rates in four trials, even in women who had prolapse in addition to stress incontinence. The need for repeat incontinence surgery also appeared less after the abdominal operation, but this was only reported in one small trial. However, there was not enough information about post-operative complications and morbidity.

Conservative management of post prostatectomy incontinence.

BACKGROUND: Urinary incontinence after prostatectomy is a common problem. Conservative management of this condition includes pelvic floor muscle training, biofeedback, electrical stimulation using a rectal electrode, transcutaneous electrical nerve stimulation, or a combination of methods. OBJECTIVES: To assess the effects of conservative management for urinary incontinence after transurethral, suprapubic, radical retropubic or perineal prostatectomy. SEARCH STRATEGY: The Cochrane Incontinence Group's trials register, Medline, Cinahl, Embase, PsycLit and ERIC all up to January 1999, and reference lists of relevant articles. We contacted investigators to locate studies and we handsearched the following conference proceedings: American Urological Association (1989-1999); Society of Urologic Nurses and Associates (1991-1998); Wound Ostomy and Continence Nurses (1996-1999); and International Continence Society (1980-1998). Date of most recent searches: January 1999. SELECTION CRITERIA: Randomised or quasi-randomised trials which evaluated conservative management aimed at improving urinary continence after prostatectomy. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the methodological quality of studies and abstracted data from included trials onto a standard form. MAIN RESULTS: Only five randomised trials were identified which included 365 men, each evaluating different treatments, and all studying men after radical prostatectomy. The trials were of moderate quality and data were not available for many of the pre-stated outcomes. Confidence intervals for both dichotomous and continuous data were wide; it was not possible to reliably identify or rule out a useful effect. Men's symptoms tended to improve over time, irrespective of management. REVIEWER'S CONCLUSIONS: The value of the various approaches to conservative management of post prostatectomy incontinence remains uncertain. Further well designed trials are needed.

Desmopressin for nocturnal enuresis in children.

BACKGROUND: Enuresis (bedwetting) is a socially disruptive and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. OBJECTIVES: To assess the effects of desmopressin on nocturnal enuresis in children, and to compare desmopressin with other interventions. SEARCH STRATEGY: The following electronic databases were searched: MEDLINE to June 1997; AMED; ASSIA; BIDS; BIOSIS Previews (1985-1996); CINAHL; DHSS Data; EMBASE (1974 to June 1997); PsycLIT and SIGLE. Organisations, manufacturers, researchers and health professionals concerned with enuresis were contacted for information. The reference sections of obtained studies were also checked for further trials. Date of the most recent search: July 1997. SELECTION CRITERIA: All randomised trials of desmopressin for nocturnal enuresis in children were included in the review. Trials were eligible for inclusion if: children were randomised to receive desmopressin compared with placebo, other drugs or other conservative interventions for nocturnal bedwetting; participants with organic causes for their bedwetting were excluded; and baseline assessments of the level of bedwetting were reported. Trials focused solely on daytime wetting were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the quality of the eligible trials, and extracted data. MAIN RESULTS: Twenty one randomised trials involving 948 children treated with desmopressin, met the inclusion criteria. The quality of many of the trials was poor. Desmopressin was compared with a tricyclic drug in two trials, and with alarms in one. Desmopressin was effective in reducing bedwetting in a variety of doses and forms. Each dose of desmopressin reduced bedwetting by at least one night per week during treatment (eg 20microg: 1.56 fewer wet nights per week, 95% CI -1.94 to -1.19). Participants on desmopressin were 4.6 times more likely to achieve 14 consecutive dry nights (95% CI 1.38 to 15.02) compared with placebo. However, there was no difference after treatment was finished. There was no apparent dose-related effect of desmopressin, but the evidence was limited. Data which compared oral and nasal administration were too few to be conclusive. Desmopressin and imipramine (a tricyclic drug) were equally effective in one small trial. Amitriptyline (another tricyclic) was not consistently better than desmopressin either alone or when used as a supplement. In a single trial, desmopressin was initially superior to using an alarm in reducing the number of wet nights per week: WMD -1.7 (95% CI: -2.96 to -0.45), but this result was not sustained; after three months of treatment, patients using the alarm had 1.4 fewer wet nights per week than with desmopressin: (95% CI: 0.14 to 2.65). Participants receiving the alarm intervention were also nine times less likely to relapse than those given desmopressin: RR 9.2 (95% CI: 1.28 to 65.9). Combining alarm and drug therapy was found to be superior to alarm treatment alone. The addition of desmopressin to an alarm schedule resulted in one less wet night per week: (95% CI: -1.55 to -0.45). REVIEWER'S CONCLUSIONS: Desmopressin rapidly reduced the number of wet nights per week, but there was some evidence that this was not sustained after treatment stopped. Comparison with alternative treatments suggested that desmopressin and tricyclics had similar clinical effects, but that alarms produced more sustained benefits. However, based on the available evidence, these conclusions can only be tentative. There was some evidence of minor side effects of desmopressin in the included trials, such as nasal irritation and nose bleeds. However, the risk of water intoxication associated with over-drinking before bedtime has been reported. Patients and their families need to be warned of potential adverse effects and advise

Tricyclic and related drugs for nocturnal enuresis in children.

BACKGROUND: Enuresis (bedwetting) is a socially unacceptable and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. OBJECTIVES: To assess the effects of tricyclic and related drugs on nocturnal enuresis in children, and to compare them with other interventions. SEARCH STRATEGY: The following electronic databases were searched: MEDLINE to June 1997; AMED; ASSIA; BIDS; BIOSIS Previews (1985-1996); CINAHL; DHSS Data; EMBASE (1974 to June 1997); PsycLIT and SIGLE. Organisations, manufacturers, researchers and health professionals concerned with enuresis were contacted for information. The reference sections of obtained studies were also checked for further trials. Date of the most recent search: July 1997. SELECTION CRITERIA: All randomised trials of tricyclic and related drugs for nocturnal enuresis in children were included in the review. Trials were eligible for inclusion if: children were randomised to receive tricyclics compared with placebo, other drugs or other conservative interventions for nocturnal bedwetting; participants with organic causes for their bedwetting were excluded; and baseline assessments of the level of bedwetting were provided. Trials focused solely on daytime wetting were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the quality of the eligible trials, and extracted data. MAIN RESULTS: Twenty two randomised trials, involving 1100 children treated with tricyclic or related drugs, met the inclusion criteria. The quality of many of the trials was poor. Only single trials compared tricyclic or related drugs with each other, other drugs, desmopressin, alarms or other behavioural interventions. Treatment with tricyclic drugs (such as imipramine, amitriptyline, viloxazine, clomipramine and desipramine but not mianserin) were associated with a reduction of about one wet night per week while on treatment (eg using imipramine, WMD -0.99, 95% CI -1.27 to -0.71). Children were almost five times more likely to achieve 14 dry nights with the drugs (eg using imipramine, RR = 4.99, 95% CI 2.4 to 10.40). Desmopressin and tricyclics appeared equally effective while on treatment, but this effect was not sustained after treatment stopped. There was no detectable difference between imipramine and alarms while on treatment, but afterwards those who had used alarms had one fewer wet night per week (WMD 1.03, 95% CI 0. 19 to 1.87). REVIEWER'S CONCLUSIONS: Treatment with tricyclic drugs (imipramine, amitriptyline, viloxazine, clomipramine and desipramine but not mianserin) was associated with a reduction of about one wet night per week while on treatment, but long term effectiveness is unknown. Desmopressin and tricyclics appeared equally effective while on treatment, but this effect was not sustained after treatment stopped. Alarms may be more effective in the long term. Comparisons between drug and behavioural treatments are needed, and should include relapse rates after treatment is finished.

Drugs for nocturnal enuresis in children (other than desmopressin and tricyclics).

BACKGROUND: Enuresis (bedwetting) is a socially unacceptable and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. OBJECTIVES: To assess the effects of drugs other than desmopressin and tricyclics on nocturnal enuresis in children, and to compare them with other interventions. SEARCH STRATEGY: The following electronic databases were searched: MEDLINE to June 1997; AMED; ASSIA; BIDS; BIOSIS Previews (1985-1996); CINAHL; DHSS Data; EMBASE (1974 to June 1997); PsycLIT and SIGLE. Organisations, manufacturers, researchers and health professionals concerned with enuresis were contacted for information. The reference sections of obtained studies were also checked for further trials. Date of the most recent search: July 1997. SELECTION CRITERIA: All randomised trials of drugs (excluding desmopressin or tricyclics) for nocturnal enuresis in children were included in the review. Trials were eligible for inclusion if: children were randomised to receive drugs compared with placebo, other drugs or other conservative interventions for nocturnal bedwetting; participants with organic causes for their bedwetting were excluded; and baseline assessments of the level of bedwetting were provided. Trials focused solely on daytime wetting were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the quality of the eligible trials, and extracted data. MAIN RESULTS: None of the drugs (phenmetrazine, amphetamine sulphate/ephedrine + atropine, furosemide (sic) or chlorprotixine) were better than placebo during treatment. The numbers were too small to draw reliable conclusions, and none are used in current practice in the UK. Imipramine (a tricyclic) was better than each of the three drugs with which it was compared (meprobamate, ephedrine sulphate and furosemide) even though the numbers were small. Alarm treatment was better than drugs in one small trial. REVIEWER'S CONCLUSIONS: There was not enough evidence to suggest that the included drugs reduced bedwetting. There was limited evidence to suggest that imipramine and alarms were better, and in other reviews, desmopressin, tricyclics and alarm interventions have tentatively been shown to be effective.

The prognostic power of the post-coital test for natural conception depends on duration of infertility.

Controversy about the value of the post-coital test (PCT) has prompted us to re-analyse data from 207 couples, originally studied between 1982 and 1983, with at least 12 months' infertility at presentation, complete diagnostic information and exclusion of female factors, to clarify the effect of duration of infertility on the prediction of conception. In couples with less than 3 years infertility and a positive PCT, 68% conceived within 2 years compared with 17% of those with a negative result. After 3 years, corresponding rates were 14% and 11%. The relative risks of conception [95% confidence interval (CI)] calculated using the Cox's proportional hazards model were 0.23 (0.12-0.43) for a negative PCT (reference positive PCT) and 0.25 (0.13-0.51) for more than 36 months infertility (reference 12-23 months). Semen analysis had no extra predictive power given the duration of infertility and the PCT. The PCT is an effective predictor of conception where defined female causes of infertility are absent and duration of infertility is less than 3 years. Once infertility is prolonged (beyond 3 years) the conception rate is low even with a positive test because a large proportion of couples remaining childless so long have true unexplained infertility. Use of the PCT will enable clinicians to allocate scarce, expensive and invasive resources effectively.

Neonatal examination and screening trial (NEST): a randomised, controlled, switchback trial of alternative policies for low risk infants.

OBJECTIVE: To evaluate the effectiveness of one rather than two hospital neonatal examinations in detection of abnormalities. DESIGN: Randomised controlled switchback trial. SETTING: Postnatal wards in a teaching hospital in north east Scotland. PARTICIPANTS: All infants delivered at the hospital between March 1993 and February 1995. INTERVENTION: A policy of one neonatal screening examination compared with a policy of two. MAIN OUTCOME MEASURES: Congenital conditions diagnosed in hospital; results of community health assessments at 8 weeks and 8 months; outpatient referrals; inpatient admissions; use of general practioner services; focused analysis of outcomes for suspected hip and heart abnormalities. RESULTS: 4835 babies were allocated to receive one screening examination (one screen policy) and 4877 to receive two (two screen policy). More congenital conditions were suspected at discharge among babies examined twice (9.9 v 8.3 diagnoses per 100 babies; 95% confidence interval for difference 0.3 to 2.7). There was no overall significant difference between the groups in use of community, outpatient, or inpatient resources or in health care received. Although more babies who were examined twice attended orthopaedic outpatient clinics (340 (7%) v 289 (6%)), particularly for suspected congenital dislocation of the hip (176 (3.6/100 babies) v 137 (2.8/100 babies); difference -0.8; -1.5 to 0.1), there was no significant difference in the number of babies who required active management (12 (0.2%) v 15 (0.3%)). CONCLUSIONS: Despite more suspected abnormalities, there was no evidence of net health gain from a policy of two hospital neonatal examinations. Adoption of a single examination policy would save resources both during the postnatal hospital stay and through fewer outpatient consultations.

Linking Community Health Index and Scottish Morbidity Records for neonates: the Grampian experience.

OBJECTIVE: To describe linking Community Health Index (CHI) records with Scottish Morbidity Records for neonates (SMR11) for the purpose of follow-up in a large clinical trial. DESIGN: A two-stage probabilistic computer match based on date of birth, surname and postcode, supplemented with hand matching. SETTING: Aberdeen Maternity Hospital, Grampian. SUBJECTS: 10,835 babies born in the two year period between 1 March 1993 and 28 February 1995. RESULTS: The computerised linkage matched 89.8% of the SMR11 records to a CHI record. All of the remaining 10.2% unlinked babies were accounted for by manual checking. There were 194 (1.8%) babies who did not have a CHI record due to the baby leaving the area or dying before allocation was possible. The sensitivity of the matching was estimated at 99.9% (95% CI is 99.8% to 100%). CONCLUSION: We were able to correctly computer match 89.7% of our babies' SMR11 records with the appropriate CHI number. We have shown that the follow-up of neonates in a clinical trial setting using record linkage between secondary and primary care systems is feasible, efficient and useful. However, this exercise would have been greatly facilitated by a unique NHS identifier common to all records.

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.

Sexual function after childbirth: women's experiences, persistent morbidity and lack of professional recognition.

OBJECTIVE: To describe the sexual behaviour of postnatal women, including time of restarting intercourse, problems encountered, use of contraception and related use of available services. DESIGN: Longitudinal survey using postal questionnaires following discharge from hospital, and at eight weeks and twelve to eighteen months postnatally. SETTING: The questionnaires referred to postnatal care received in a teaching hospital and general practitioner delivery units, and in the community. POPULATION: Randomly selected one in five sample of women who were delivered in the Grampian Region of Scotland over a 12-month period. MAIN OUTCOME MEASURES: Times to restarting intercourse and contraception; problems related to intercourse and their relation to perineal pain, tiredness and method of infant feeding; and perceived need for and adequacy of help. RESULTS: The median times to restarting intercourse and contraception were each six weeks. Problems with intercourse were reported by 569/1075 (53%, 95% CI 50-56) of women in the first eight weeks after delivery, and by 215/435 (49%, 95% CI 45-54) in the subsequent year. Women who reported perineal pain, depression or tiredness experienced problems related to intercourse more often than those who did not. Women who breastfed their infants were significantly less interested in intercourse than those who bottlefed, irrespective of tiredness or depression, but this effect did not persist in the long term. The need for help with problems was expressed by 7% to 13% of women, but a quarter of these had not sought it. CONCLUSIONS: Postnatal sexual problems are common. Health professionals ought to educate and prepare patients antenatally; be trained to identify problems; and be competent to deal with them openly and sympathetically.
