Association between congenital foot anomalies and gestational age at amniocentesis.
OBJECTIVES: Our objectives were to confirm the reported association between early amniocentesis and congenital foot anomalies as well as to report, for the first time, on the outcome of amniocenteses performed during the 13th and 14th weeks of gestation. METHODS: We conducted a triple cohort retrospective study of 4457 amniocenteses. Cohort definitions: early amniocentesis (EA), 11 weeks and 0/7 days to 12 weeks to 6/7 days; early midtrimester amniocentesis (EMA), 13 weeks and 0/7 days to 14 weeks and 6/7 days; and midtrimester amniocentesis (MA), 15 weeks and 0/7 days to 19 weeks and 6/7 days. Outcome measures were obtained by searching the Alberta Congenital Anomalies Surveillance System (ACASS) database for children born with foot anomalies represented by International Classification of Diseases version 9 (ICD-9) codes 754.5, 754.6 and 754.7. RESULTS: Incidences of congenital foot anomalies were: EA 11/980 (1.1%), EMA 11/2515 (0.4%), and MA 1/962 (0.1%). There is a significant difference between the EA and EMA cohorts (p=0.019) and between the EA and MA cohorts (p=0.003); however, these data suggest there is no difference between EMA and MA cohorts (p=0.11). CONCLUSIONS: Our incidence of congenital foot anomalies of 1.1% for women who underwent EA is similar to previously reported data, which further validates this association; however, our data also suggest that the foot anomaly risk may be limited to amniocenteses performed before the 13th week of gestation.
Citizens' expectations and likely use of a NHS Walk-in Centre: results of a survey and qualitative methods of research.
OBJECTIVES: To find out which groups of people would use a National Health Service walk-in centre that would offer mainly health care advice, staffed by nurses. To understand the circumstances in which people would use a walk-in centre and to ascertain to what extent it would meet patients' expressed health-care needs. DESIGN: A postal survey of 2400 people plus 27 semi-structured interviews and one focus group. SETTING AND PARTICIPANTS: The study was conducted in Wakefield, Yorkshire UK, and included both white and ethnic minority groups. RESULTS: Most people reported that they would use a walk-in centre. It would be more attractive to young as compared with older people, ethnic minority as compared with white people, people who are dissatisfied with access to NHS services and people with urgent health-care problems. People want a wide range of services, including diagnosis, treatment, prevention, and general information. People also want access to both doctors and nurses, to male as well as female practitioners, to counsellors and interpreters. The type of service planned for this walk-in centre will meet some of the expressed needs. However, patients' expectations of the walk-in centre exceed planned provision in a number of key respects. CONCLUSION: Walk-in centres without GPs and with limited services will disappoint the public. It is important that walk-in centres are evaluated and attention paid to 'local voices' before additional money is allocated for such centres elsewhere.
A profile of PMS salaried GP contracts and their impact on recruitment.
BACKGROUND: Personal medical services (PMS) pilot sites aim to use salaried GP schemes to improve GP recruitment and retention and enhance the quality of service provision, particularly in underserved areas. OBJECTIVES: Our objectives were to (i) compare the work incentives of salaried compared with standard GP contracts; (ii) assess recruitment success to salaried posts; and (iii) describe the types of GPs attracted to these new posts. METHOD: All first wave PMS pilot sites with salaried GP posts known to be 'live' in October 1998 were included in the analysis of employment contracts and job descriptions. Information on recruitment was obtained by a questionnaire survey of PMS sites that were intending to recruit a salaried GP. RESULTS: The mean full-time equivalent salary was 43,674 pounds sterling with additional benefits in terms of sick leave, maternity leave and paid expenses. Eighty-nine percent of posts were eligible for the NHS pension scheme. Posts were mainly full time (40.8 hours per week). GPs were responsible for providing services equivalent in scope to general medical services. One-fifth of contracts freed GPs from out-of-hours responsibility and most freed them from practice management. Forty-three of the pilot sites actively recruited to fill 63 salaried posts, which involved a total of 51 recruitment 'rounds', with some pilots advertising more than once. There were 291 applications. The median number of applicants per post was three and the median time to recruitment was 6 weeks. Eighty-five percent of sites were satisfied with the quality of their applicants and 64% with the quantity. Eighty-five percent of applicants previously had been working in general practice, most in locum or salaried posts. Applicants tended to be young and male. Sixty posts were filled. CONCLUSIONS: Salaried contracts offer positive incentives to recruitment in terms of reduced hours of work and freedom from administrative responsibility. Recruitment success was similar to that achieved by inner city practices generally. This modest achievement might be enhanced by the addition of professional development schemes and increased flexible/part-time working.
The treatment of child and adolescent mental health problems in primary care: a systematic review.
BACKGROUND: There is significant potential to increase the accessibility and effectiveness of child and adolescent mental health services through the involvement of primary care professionals and the delivery of interventions in the primary care setting. However, little is known about the actual clinical and cost-effectiveness of such service delivery. OBJECTIVE: The aim of the study was to review systematically the evidence concerning the effectiveness of interventions for child and adolescent mental health problems in primary care, and interventions designed to improve the skills of primary care staff. METHODS: Searches were made of The Cochrane Clinical Trials Register, MEDLINE, PSYCINFO, EMBASE and CINAHL, together with correspondence with subject experts and authors of studies, and checking of references in identified papers. RESULTS AND CONCLUSIONS: There was some preliminary evidence that treatments by specialist staff working in primary care were effective, although the quality of included studies was variable and no data were available on the cost-effectiveness of interventions. Equally, some educational interventions show potential for increasing the skills and confidence of primary care staff, but controlled evaluations were rare and few studies reported actual changes in professional behaviour or patient health outcomes. A significant programme of research is required if the potential for child and adolescent mental health services in primary care is to be realized in an effective and efficient way.

Completeness and accuracy of the birth registry data on congenital anomalies in Alberta, Canada.
Vital statistics and other administrative data are becoming an increasingly important source for epidemiologic research and surveillance. This study, the first in Canada, evaluated the usefulness of birth registry data on congenital anomalies in Alberta. We compared the number of birth defects recorded in the birth registry with the number collected through the Alberta Congenital Anomalies Surveillance System (ACASS) between 1985 and 1996. In addition, records of 3,881 (99.9 %) babies with (a) birth defect(s) from the ACASS during 1994--1996 were matched to the birth registry by deterministic linkage. Of these, 2,969 babies had single anomalies that were used for validity analysis. The anomalies were grouped by those within International Classification of Disease (ICD) ICD-9 Section XIV (ICD-9=740.0-759.9) and those outside the Section XIV. For those within Section XIV, 24 summary diagnostic categories were examined. As shown, the total case count from the birth registry was on average about 3 % lower than that from the ACASS between 1985 and 1996. The validity of diagnostic categories is high for the 24 categories examined, with an overall agreement of between 80 % and 100 %. The sensitivity, positive predictive value, and kappa are also high for all these anomalies combined during 1994 and 1996, showing 95.7 %, 99.8, and 0.81 respectively.

Randomised controlled trial of non-directive counselling, cognitive-behaviour therapy, and usual general practitioner care for patients with depression. I: clinical effectiveness.
OBJECTIVE: To compare the clinical effectiveness of general practitioner care and two general practice based psychological therapies for depressed patients. DESIGN: Prospective, controlled trial with randomised and patient preference allocation arms. SETTING: General practices in London and greater Manchester. PARTICIPANTS: 464 of 627 patients presenting with depression or mixed anxiety and depression were suitable for inclusion. INTERVENTIONS: Usual general practitioner care or up to 12 sessions of non-directive counselling or cognitive-behaviour therapy provided by therapists. MAIN OUTCOME MEASURES: Beck depression inventory scores, other psychiatric symptoms, social functioning, and satisfaction with treatment measured at baseline and at 4 and 12 months. RESULTS: 197 patients were randomly assigned to treatment, 137 chose their treatment, and 130 were randomised only between the two psychological therapies. All groups improved significantly over time. At four months, patients randomised to non-directive counselling or cognitive-behaviour therapy improved more in terms of the Beck depression inventory (mean (SD) scores 12.9 (9.3) and 14.3 (10.8) respectively) than those randomised to usual general practitioner care (18.3 (12.4)). However, there was no significant difference between the two therapies. There were no significant differences between the three treatment groups at 12 months (Beck depression scores 11.8 (9.6), 11.4 (10.8), and 12.1 (10.3) for non-directive counselling, cognitive-behaviour therapy, and general practitioner care). CONCLUSIONS: Psychological therapy was a more effective treatment for depression than usual general practitioner care in the short term, but after one year there was no difference in outcome.
Randomised controlled trial of non-directive counselling, cognitive-behaviour therapy, and usual general practitioner care for patients with depression. II: cost effectiveness.
OBJECTIVE: To compare the cost effectiveness of general practitioner care and two general practice based psychological therapies for depressed patients. DESIGN: Prospective, controlled trial with randomised and patient preference allocation arms. SETTING: General practices in London and greater Manchester. PARTICIPANTS: 464 of 627 patients presenting with depression or mixed anxiety and depression were suitable for inclusion. INTERVENTIONS: Usual general practitioner care or up to 12 sessions of non-directive counselling or cognitive-behaviour therapy provided by therapists. MAIN OUTCOME MEASURES: Beck depression inventory scores, EuroQol measure of health related quality of life, direct treatment and non-treatment costs, and cost of lost production. RESULTS: 197 patients were randomly assigned to treatment, 137 chose their treatment, and 130 were randomised only between the two psychological therapies. At four months, both non-directive counselling and cognitive-behaviour therapy reduced depressive symptoms to a significantly greater extent than usual general practitioner care. There was no significant difference in outcome between treatments at 12 months. There were no significant differences in direct costs, production losses, or societal costs between the three treatments at either four or 12 months. Sensitivity analyses did not suggest that the results depended on particular assumptions in the statistical analysis. CONCLUSIONS: Within the constraints of available power, the data suggest that both brief psychological therapies may be significantly more cost effective than usual care in the short term, as benefit was gained with no significant difference in cost. There are no significant differences between treatments in either outcomes or costs at 12 months.
