A comprehensive systematic review of evidence on the effectiveness and appropriateness of undergraduate nursing curricula.
Objectives The objective of this review was to appraise and synthesise the best available evidence on the effectiveness and appropriateness of undergraduate nursing curricula. Inclusion criteria This review considered research papers that addressed the effectiveness and appropriateness of undergraduate nursing curricula. Studies of higher evidence levels were given priority over lower-evidence studies. ⋯ It was possible to examine the effectiveness of an integrated curriculum model and a subject-centred curriculum model; however, the other two models could not be compared because of a lack of evidence. Conclusion The evidence regarding the effectiveness and appropriateness of undergraduate nursing curricula is notably weak because of the paucity of high-quality comparative studies and meaningful outcome measures of available studies. Therefore, no strong conclusion can be made regarding the effectiveness and appropriateness of undergraduate nursing curricula.

Implementation of oral health recommendations into two residential aged care facilities in a regional Australian city.
Background Residents of aged care facilities usually have a large number of oral health problems. Residents who suffer from dementia are at particular risk. A systematic review of the best available evidence with regard to maintaining the oral health of older people with dementia in residential aged care facilities provided a number of recommendations. ⋯ Conclusion The majority of recommendations provided in the systematic review of oral healthcare for dementia patients were applicable to the applied context. The importance of day-to-day leaders was highlighted by the apparently varied outcomes across target facilities. The quality improvement approach would appear to have considerable advantages when applied to improving practice in residential aged care.

Nursing and midwifery management of hypoglycaemia in healthy term neonates.
EXECUTIVE SUMMARY: ⋯ The seven studies analysed in this review confirm the World Health Organisation's first three recommendations for prevention and management of asymptomatic hypoglycaemia, namely: 1 Early and exclusive breast-feeding is safe to meet the nutritional needs of healthy term newborns worldwide. 2 Healthy term newborns that are breast-fed on demand need not have their blood glucose routinely checked and need no supplementary foods or fluids. 3 Healthy term newborns do not develop 'symptomatic' hypoglycaemia as a result of simple underfeeding. If an infant develops signs suggesting hypoglycaemia, look for an underlying condition. Detection and treatment of the cause are as important as correction of the blood glucose level. If there are any concerns that the newborn infant might be hypoglycaemic it should be given another feed. Given the importance of thermoregulation, skin-to-skin contact should be promoted and 'kangaroo care' encouraged in the first 24 h after birth. While it is important to main the infant's body temperature care should be taken to ensure that the child does not become overheated.

Association between pacifier use and breast-feeding, sudden infant death syndrome, infection and dental malocclusion.
To critically review all literature related to pacifier use for full-term healthy infants and young children. The specific review questions addressed are: What is the evidence of adverse and/or positive outcomes of pacifier use in infancy and childhood in relation to each of the following subtopics: • breast-feeding; • sudden infant death syndrome; • infection; • dental malocclusion. ⋯ With regard to the breast-feeding outcome, 10 studies met the inclusion criteria, comprising two randomised controlled trials and eight cohort studies. The research was conducted between 1995 and 2003 in a wide variety of settings involving research participants from diverse socioeconomic and cultural backgrounds. Information regarding exposure and outcome status, and potential confounding factors was obtained from: antenatal and postnatal records; interviews before discharge from obstetric/midwifery care; post-discharge interviews; and post-discharge postal and telephone surveys. Both the level of contact and the frequency of contact with the informant, the child's mother, differed widely. Pacifier use was defined and measured inconsistently, possibly because few studies were initiated expressly to investigate its relationship with breast-feeding. Completeness of follow-up was addressed, but missing data were not uniformly identified and explained. When comparisons were made between participants and non-participants there was some evidence of differential loss and a bias towards families in higher socioeconomic groups. Multivariate analysis was undertaken in the majority of studies, with some including a large number of sociodemographic, obstetric and infant covariates and others including just maternal age and education. As might be expected given the inconsistency of definition and measurement, the relationship between pacifier use and breast-feeding was expressed in many different ways and a meta-analysis was not appropriate. In summary, only one study did not report a negative association between pacifier use and breast-feeding duration or exclusivity. Results indicate an increase in risk for a reduced overall duration of breast-feeding from 20% to almost threefold. The data suggest that very infrequent use may not have any overall negative impact on breast-feeding outcomes. Six sudden infant death syndrome case-control studies met the criteria for inclusion. The research was conducted with information gathered between 1984 and 1999 in Norway, UK, New Zealand, the Netherlands and USA. Exposure information was obtained from a variety of sources including: hospital and antenatal records, death scene investigation, and interview and questionnaire. Information for cases was sought within 2 days after death, within 2-4 weeks after death and in one study between 3 and 11 years after death. Information for controls was sought from as early as 4 days of a nominated sudden infant death syndrome case, to between 1 and 7 weeks from the case date, and again in one study some 3-11 years later. In the majority of the studies case ascertainment was determined by post-mortem. Pacifier use was again defined and measured somewhat inconsistently. All studies controlled for confounding factors by matching and/or using multivariate analysis. Generally, antenatal and postnatal factors, as well as infant care practices, and maternal, family and socioeconomic issues were considered. (ABSTRACT TRUNCATED)

Effectiveness of a pelvic floor muscle exercise program on urinary incontinence following childbirth.
EXECUTIVE SUMMARY: Objectives The primary objective of this review was to determine, from the available evidence, the effectiveness of an antenatal and/or a post-natal program of pelvic floor muscle exercises (PFME) compared with usual care on preventing, reducing or resolving the incidence and severity of stress incontinence, urge incontinence or mixed stress and urge urinary incontinence following childbirth. Secondary objectives were included to examine the effectiveness of a PFME program on pelvic floor muscle strength and on encouraging adherence to an exercising program. ⋯ Outcomes that were of interest: • non-occurrence of urinary incontinence following childbirth; • a change in the frequency, duration or severity (as appropriate) of urinary incontinence up to 12 months following childbirth. • a change in the strength of pelvic floor muscle contractions; • period of time PFME continued after initial instruction; • frequency of PFME undertaken; • women's awareness of the importance of PFME; • satisfaction with PFME instruction. Search strategy All major electronic sources of information relevant to the topic (e.g. PubMed, CINAHL and the Cochrane Library) were searched to identify published and unpublished studies and previous work in the field. Printed journals were hand-searched and reference lists checked for potentially useful research. The review included any studies undertaken between 1981 and 2003. The search did not attempt to locate unpublished research before 1991. Assessment of quality An independent Review Panel carried out quality assessment of studies. Two members of the panel, using quality assessment checklists developed for the review, reviewed each study. Disagreements between reviewers were resolved through discussion or a third reviewer examining a study. Data extraction and analysis A data extraction tool was developed to extract data relating to participant characteristics, study methods, interventions and outcomes. Two reviewers independently extracted the required data. Randomised controlled trials included in the review were pooled in several meta-analyses using RevMan software program. Heterogeneity between studies was determined to ensure that they were sufficiently similar to allow for the pooling of their results. Non-randomised controlled trials were discussed in narrative comparisons. Results Six randomised controlled trials met the inclusion criteria for the primary objective of the systematic review. The results of this review indicate that antenatal PFME and post-natal PFME are effective in resolving or reducing urinary incontinence following childbirth. There was insufficient evidence to conclude that PFME can prevent urinary incontinence in post-partum women. In most of these studies women were selected randomly and therefore included women without urinary incontinence and women with urinary incontinence. Two randomised controlled trials selected their sample on the criteria of existing post-partum urinary incontinence. A subgroup analysis of these studies showed that post-natal PFME also have a significant effect on reducing or resolving urinary incontinence in women with existing post-partum urinary incontinence. Seven randomised controlled trials and three non-randomised controlled trials met the inclusion criteria for the secondary objectives of the review. Findings of the studies included in the review suggest a PFME program will improve the frequency with which women perform PFME. Two studies found that women receiving the intervention (a PFME program) and who were performing PFME regularly in the month before data collection were significantly less likely to have any incontinence. The review's results support previous findings showing there is little evidence that a high-intensity PFME program is more effective than a low-intensity PFME regimen of exercising. No conclusions about the effectiveness of feedback to a woman about pelvic floor muscle strength, for example, perineometer measures, as part of a PFME program can be reached. The mixed results of this review mean that no conclusions can be reached about the effectiveness of a PFME program, antenatal or post-natal, on improving pelvic floor muscle strength. A number of studies reported a high percentage of women lost to follow-up and the data collected in most of the studies relied on self-reports relating to urinary incontinence and/or frequency of exercising. These factors may have affected the overall results of the review. However, wherever possible, tests for heterogeneity were carried out to determine if studies should be combined in meta-analyses and in other cases the results' limitations are acknowledged. Implications for practice In terms of the effectiveness of PFME programs, the results of this review indicate that urinary incontinence following childbirth can be improved by performing PFME and that any form of a specific PFME program appears to improve exercising frequency. However, the value of individual components of PFME programs, such as take-home materials, reminder telephone calls and feedback of exercising effectiveness, is less clear. • Encourage women to undertake both antenatal and post-natal PFME (E1). • Pay particular attention to women with antenatal and post-natal urinary incontinence in providing advice and PFME instruction (E1). • To encourage adherence and continuation, PFME education programs should be multifaceted with a number of components, rather than only supplying an information booklet (E4). • Include PFME as a specific program in all antenatal and post-natal care, incorporating at least two individual instruction sessions into the program (E1). • Provide post-partum contact, particularly for those discharged early, either by telephone, electronic or home visits (E4). • Design pelvic floor muscle home exercise programs that are realistic given the demands on a mother and that can be incorporated into her daily routine in terms of number and frequency. Two or more training sessions per week are recommended (E4). • Health professionals working with women in the post-partum period should ask about symptoms of incontinence to ensure assistance is offered to those experiencing urinary incontinence (E4).
