Assessing the effectiveness of decision aids for decision making in prostate cancer testing: a systematic review.

BACKGROUND: Prostate cancer is a leading disease affecting men worldwide. Conflicting evidence within the literature provides little guidance to men contemplating whether or not to be screened for prostate cancer. This systematic review aimed to determine whether decision aids about early detection of prostate cancer improve patient knowledge and decision making about whether to undergo prostate-specific antigen testing. METHODS: Medline, EMBASE, CINAHL, PsychINFO, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and Health Technology Assessment databases up until March 2014 were searched. All included randomised controlled trials were assessed for methodological quality. Clinical selection and assessment heterogeneity among studies prevented the pooling of data for meta-analyses. Descriptive analyses of all included studies and comparison were performed. RESULTS: A total of 13 randomised controlled trials met the inclusion criteria. Significant heterogeneity was present for the design and implementation of decision aids including comparative interventions and outcomes. Eight studies were of a low methodological quality, with the remaining five of medium quality. Improvements in patient knowledge following use of a decision aid were demonstrated by 11 of the 13 included studies. Seven of 10 studies demonstrated a reduction in decisional conflict/distress. Three of four studies demonstrated no difference between a decision aid and information only in reducing decisional uncertainty. Three of five studies demonstrated an increase in decisional satisfaction with use of a decision aid. CONCLUSIONS: Decision aids increase patient knowledge and confidence in decision making about prostate cancer testing. Further research into effective methods of implementation is needed.

Prevalence correlates and impact of fecal incontinence among older women.

BACKGROUND: Fecal incontinence is a common problem that has been associated with anatomic, physiological, and medical conditions. There are very few data on the factors associated with fecal incontinence in elderly women. OBJECTIVES: We aimed to determine the factors associated with fecal incontinence via a population-based survey in a large cohort of elderly Australian women. DESIGN AND SETTING: Data from a large longitudinal population-based study of elderly Australian women aged 82 to 87 years were analyzed. PATIENTS: Participants were 5560 women (aged 82-87 years) who participated in the Australian Longitudinal Study on Women's Health; 4815 women responded to questions relating to fecal incontinence. MAIN OUTCOME MEASURES: Fecal incontinence was defined as leakage of liquid and/or solid stool at least once per month over the past 12 months. Self-reported medical conditions and lifestyle factors as well as demographic factors were recorded. RESULTS: The prevalence of fecal incontinence was 10.4% (95% CI, 9.6-11.3) (n = 510). The prevalence was significantly higher among institutional- versus community-dwelling women (14.1% vs 9.7%; p = 0.0002). Univariately, lifestyle factors including fruit intake and fluid intake, along with a range of comorbidities, were associated. However, independent factors for fecal incontinence among community-dwelling women included diabetes mellitus (OR, 1.51; 95% CI, 1.14-2.01; p = 0.004), depression (OR, 1.84; 95% CI, 1.30-2.62; p = 0.001), urinary incontinence (OR, 2.29; 95% CI, 1.83-2.86; p < 0.0001), and osteoarthritis (OR, 0.73; 95% CI, 0.57-0.94; p = 0.013). Among institutional-dwelling women, however, we found urinary incontinence (OR, 4.43; 95% CI, 2.83-6.93; p < 0.0001) and poorer general health (OR, 0.98; 95% CI, 0.97-0.99; p = 0.003) to be independently associated. LIMITATIONS: This is a cross-sectional study, which prevents making conclusions about the cause and effect of observed correlations. CONCLUSIONS: The independent factors associated with fecal incontinence in this population do not appear readily modifiable, and many previously identified risk factors may not be important in the elderly women with fecal incontinence.

No association between previous Caesarean-section delivery and back pain in mid-aged Australian women: an observational study.

QUESTION: Is there an association between Caesarean section and back pain over the longer term? DESIGN: Secondary analysis of data from the Australian Longitudinal Study on Women's Health. PARTICIPANTS: The mid-aged cohort of women within the Australian Longitudinal Study on Women's Health aged 54 to 59 years (n = 9146). OUTCOME MEASURES: Data were included from women who answered the question regarding back pain. Data were extracted on whether they had given birth and, if so, whether it was by Caesarean section. Then, data on confounding variables (such as arthritis, asthma, osteoporosis, hysterectomy, ovaries removed, and repair of prolapsed vagina, bladder or bowel, menopause, smoking) were also extracted. RESULTS: After adjusting for confounding factors, women who delivered by Caesarean section had the same odds (OR 1.03, 95% CI 0.81 to 1.31) of having back pain as women who had not had a birth. CONCLUSION: Previous delivery by Caesarean section is not associated with increased back pain in mid-aged Australian women.
