ItemNo Preview AvailablePatients' preferences for involvement in treatment decision making in Japan.(Springer Science and Business Media LLC, 2004-03-01)BACKGROUND: A number of previous studies have suggested that the Japanese have few opportunities to participate in medical decision-making, as a result both of entrenched physician paternalism and national characteristics of dependency and passivity. The hypothesis that Japanese patients would wish to participate in treatment decision-making if adequate information were provided, and the decision to be made was clearly identified, was tested by interview survey. METHODS: The subjects were diabetic patients at a single outpatient clinic in Kyoto. One of three case study vignettes (pneumonia, gangrene or cancer) was randomly assigned to each subject and, employing face-to-face interviews, the subjects were asked what their wishes would be as patients, for treatment information, participation in decision-making and family involvement. RESULTS: 134 patients participated in the study, representing a response rate of 90%. The overall proportions of respondents who preferred active, collaborative, and passive roles were 12%, 71%, and 17%, respectively. Respondents to the cancer vignette were less likely to prefer an active role and were more likely to prefer family involvement in decision-making compared to non-cancer vignette respondents. If a physician's recommendation conflicted with their own wishes, 60% of the respondents for each vignette answered that they would choose to respect the physician's opinion, while few respondents would give the family's preference primary importance. CONCLUSIONS: Our study suggested that a majority of Japanese patients have positive attitudes towards participation in medical decision making if they are fully informed. Physicians will give greater patient satisfaction if they respond to the desire of patients for participation in decision-making.

ItemNo Preview AvailableThe PAV trial: does lactobacillus prevent post-antibiotic vulvovaginal candidiasis? Protocol of a randomised controlled trial [ISRCTN24141277].(Springer Science and Business Media LLC, 2004-03-28)BACKGROUND: Complementary and alternative medicines are used by many consumers, and increasingly are being incorporated into the general practitioner's armamentarium. Despite widespread usage, the evidence base for most complementary therapies is weak or non-existent. Post-antibiotic vulvovaginitis is a common problem in general practice, for which complementary therapies are often used. A recent study in Melbourne, Australia, found that 40% of women with a past history of vulvovaginitis had used probiotic Lactobacillus species to prevent or treat post-antibiotic vulvovaginitis. There is no evidence that this therapy is effective. This study aims to test whether oral or vaginal lactobacillus is effective in the prevention of post-antibiotic vulvovaginitis. METHODS/DESIGN: A randomised placebo-controlled blinded 2 x 2 factorial design is being used. General practitioners or pharmacists approach non-pregnant women, aged 18-50 years, who present with a non-genital infection requiring a short course of oral antibiotics, to participate in the study. Participants are randomised in a four group factorial design either to oral lactobacillus powder or placebo and either vaginal lactobacillus pessaries or placebo. These interventions are taken while on antibiotics and for four days afterwards or until symptoms of vaginitis develop. Women self collect a vaginal swab for culture of Candida species and complete a survey at baseline and again four days after completing their study medications. The sample size (a total of 496--124 in each factorial group) is calculated to identify a reduction of half in post-antibiotic vulvovaginitis from 23%, while allowing for a 25% drop-out. An independent Data Monitoring Committee is supervising the trial. Analysis will be intention-to-treat, with two pre-specified main comparisons: (i) oral lactobacillus versus placebo and (ii) vaginal lactobacillus versus placebo.

ItemThe association between intimate partner violence, alcohol and depression in family practice(BMC, 2010-09-27)BACKGROUND: Depressive symptoms, intimate partner violence and hazardous drinking are common among patients attending general practice. Despite the high prevalence of these three problems; the relationship between them remains relatively unexplored. METHODS: This paper explores the association between depressive symptoms, ever being afraid of a partner and hazardous drinking using cross-sectional screening data from 7667 randomly selected patients from a large primary care cohort study of 30 metropolitan and rural general practices in Victoria, Australia. The screening postal survey included the Center for Epidemiological Studies Depression Scale, the Fast Alcohol Screening Test and a screening question from the Composite Abuse Scale on ever being afraid of any intimate partner. RESULTS: 23.9% met criteria for depressive symptoms. A higher proportion of females than males (20.8% vs. 7.6%) reported ever being afraid of a partner during their lifetime (OR 3.2, 95%CI 2.5 to 4.0) and a lower proportion of females (12%) than males (25%) were hazardous drinkers (OR 0.4; 95%CI 0.4 to 0.5); and a higher proportion of females than males (20.8% vs. 7.6%) reported ever being afraid of a partner during their lifetime (OR 3.2, 95%CI 2.5 to 4.0). Men and women who had ever been afraid of a partner or who were hazardous drinkers had on average higher depressive symptom scores than those who had never been afraid or who were not hazardous drinkers. There was a stronger association between depressive symptoms and ever been afraid of a partner compared to hazardous drinking for both males (ever afraid of partner; Diff 6.87; 95% CI 5.42, 8.33; p < 0.001 vs. hazardous drinking in last year; Diff 1.07, 95% CI 0.21, 1.94; p = 0.015) and females (ever afraid of partner; Diff 5.26; 95% CI 4.55, 5.97; p < 0.001 vs. hazardous drinking in last year; Diff 2.23, 95% CI 1.35, 3.11; p < 0.001), even after adjusting for age group, income, employment status, marital status, living alone and education level. CONCLUSIONS: Strategies to assist primary care doctors to recognise and manage intimate partner violence and hazardous drinking in patients with depression may lead to better outcomes from management of depression in primary care.

ItemWomen's evaluation of abuse and violence care in general practice: a cluster randomised controlled trial (weave)(BMC, 2010-01-02)BACKGROUND: Intimate partner abuse (IPA) is a major public health problem with serious implications for the physical and psychosocial wellbeing of women, particularly women of child-bearing age. It is a common, hidden problem in general practice and has been under-researched in this setting. Opportunities for early intervention and support in primary care need to be investigated given the frequency of contact women have with general practice. Despite the high prevalence and health consequences of abuse, there is insufficient evidence for screening in primary care settings. Furthermore, there is little rigorous evidence to guide general practitioners (GPs) in responding to women identified as experiencing partner abuse. This paper describes the design of a trial of a general practice-based intervention consisting of screening for fear of partner with feedback to GPs, training for GPs, brief counselling for women and minimal practice organisational change. It examines the effect on women's quality of life, mental health and safety behaviours. METHODS/DESIGN: weave is a cluster randomised controlled trial involving 40 general practices in Victoria, Australia. Approximately 500 women (16-50 years) seen by the GP in the previous year are mailed a short lifestyle survey containing an item to screen for IPA. Women who indicate that they were afraid of a partner/ex-partner in the last year and provide contact details are invited to participate. Once baseline data are collected, GPs are randomly assigned to either a group involving healthy relationship and responding to IPA training plus inviting women for up to 6 sessions of counselling or to a group involving basic education and usual care for women. Outcomes will be evaluated by postal survey at 6 and 12 months following delivery of the intervention. There will be an economic evaluation, and process evaluation involving interviews with women and GPs, to inform understanding about implementation and outcomes. DISCUSSION: The weave trial responds to an urgent need for more evidence on what can be achieved in primary care with regard to responding to women who experience IPA. It will provide important knowledge about the effectiveness of a brief method of screening, professional IPA training program and brief counselling for women. TRIAL REGISTRATION: [ACTRN12608000032358].

ItemEffect of lactobacillus in preventing post-antibiotic vulvovaginal candidiasis: a randomised controlled trial(B M J PUBLISHING GROUP, 2004-09-04)OBJECTIVE: To test whether oral or vaginal lactobacillus can prevent vulvovaginitis after antibiotic treatment. DESIGN: Randomised, placebo controlled, double blind, factorial 2x2 trial. SETTING: Fifty general practices and 16 pharmacies in Melbourne, Australia. PARTICIPANTS: Non-pregnant women aged 18-50 years who required a short course of oral antibiotics for a non-gynaecological infection: 278 were enrolled in the study, and results were available for 235. INTERVENTIONS: Lactobacillus preparations taken orally or vaginally, or both, from enrollment until four days after completion of their antibiotic course. MAIN OUTCOME MEASURES: Participants' reports of symptoms of post-antibiotic vulvovaginitis, with microbiological evidence of candidiasis provided by a self obtained vaginal swab. RESULTS: Overall, 55/235 (23% (95% confidence interval 18% to 29%)) women developed post-antibiotic vulvovaginitis. Compared with placebo, the odds ratio for developing post-antibiotic vulvovaginitis with oral lactobacillus was 1.06 (95% confidence interval 0.58 to 1.94) and with vaginal lactobacillus 1.38 (0.75 to 2.54). Compliance with antibiotics and interventions was high. The trial was terminated after the second interim analysis because of lack of effect of the interventions. Given the data at this time, the chances of detecting a significant reduction in vulvovaginitis with oral or vaginal lactobacillus treatment were less than 0.032 and 0.0006 respectively if the trial proceeded to full enrollment. CONCLUSIONS: The use of oral or vaginal forms of lactobacillus to prevent post-antibiotic vulvovaginitis is not supported by these results. Further research on this subject is unlikely to be fruitful, unless new understandings about the pathogenesis of post-antibiotic vulvovaginitis indicate a possible role for lactobacillus.

ItemNo Preview AvailableSelf-Rated Health and Long-Term Prognosis of Depression(ANNALS FAMILY MEDICINE, 2014)PURPOSE: Indicators of prognosis should be considered to fully inform clinical decision making in the treatment of depression. This study examines whether self-rated health predicts long-term depression outcomes in primary care. METHODS: Our analysis was based on the first 5 years of a prospective 10-year cohort study underway since January 2005 conducted in 30 randomly selected Australian primary care practices. Participants were 789 adult patients with a history of depressive symptoms. Main outcome measures include risks, risk differences, and risk ratios of major depressive syndrome (MDS) on the Patient Health Questionnaire. RESULTS: Retention rates during the 5 years were 660 (84%), 586 (74%), 560 (71%), 533 (68%), and 517 (66%). At baseline, MDS was present in 27% (95% CI, 23%-30%). Cross-sectional analysis of baseline data showed participants reporting poor or fair self-rated health had greater odds of chronic illness, MDS, and lower socioeconomic status than those reporting good to excellent self-rated health. For participants rating their health as poor to fair compared with those rating it good to excellent, risk ratios of MDS were 2.10 (95% CI, 1.60-2.76), 2.38 (95% CI, 1.77-3.20), 2.22 (95% CI, 1.70-2.89), 1.73 (95% CI, 1.30-2.28), and 2.15 (95% CI, 1.59-2.90) at 1, 2, 3, 4, and 5 years, after accounting for missing data using multiple imputation. After adjusting for age, sex, multimorbidity, and depression status and severity, self-rated health remained a predictor of MDS up to 5 years. CONCLUSIONS: Self-rated health offers family physicians an efficient and simple way to identify patients at risk of poor long-term depression outcomes and to inform therapeutic decision making.

ItemGuidelines for assessing postnatal problems: introducing evidence-based guidelines in Australian general practice(OXFORD UNIV PRESS, 2003-08)BACKGROUND: Postnatal morbidity is high, and many GPs lack the confidence and knowledge to deal with common postnatal problems. There is a high consultation rate, but few women disclose common health problems. OBJECTIVE: The aim of the present study was to increase the knowledge and skills of GPs to enable them to identify and manage common health problems experienced by women in the year following childbirth. METHODS: An educational programme [Guidelines for Assessing Postnatal Problems (GAPP)] embedded within a large randomized community intervention trial [Program of Resources, Information and Support for Mothers (PRISM)] with a before/after evaluation was undergone by Australian GPs working in four metropolitan and four rural communities. The programme comprised audit, interactive workshops, role-play and evidence-based guidelines, and was evaluated at baseline and 6 months through written questionnaires and a surgery consultation with a trained simulated patient evaluator. RESULTS: A total of 68 (86%) GPs took part in the full GAPP programme. The odds of a GP improving on the knowledge items ranged from 1.0 to 16, with the greatest change occurring in knowledge about the effectiveness of cognitive behavioural therapy for maternal depression. Of the GPs with an incorrect response at baseline, the percentage demonstrating improved knowledge at follow-up ranged from 22 to 100%. Around half of the GPs demonstrated excellent communication skills at baseline. Of the remaining GPs, more than half demonstrated greatly improved skills to detect common postnatal problems at follow-up. At baseline simulated patient visit, 70% of GPs inquired about sexual problems yet none inquired about the possibility of abuse, whereas at follow-up 94% inquired about sexual problems and 51.5% facilitated the disclosure of physical and emotional abuse. Anonymous feedback on the programme by participating GPs showed that 89% believed the programme positively influenced their actual practice. Interestingly, GPs demonstrated greater knowledge and skills in the simulated setting than on the written questionnaire. CONCLUSIONS: This relatively brief multifaceted educational programme assisted many participants in improving their knowledge and the skills required to improve both physical and emotional health after birth. Despite being experienced clinicians and participating actively in a programme on interviewing skills, half of the GPs did not facilitate disclosure of the underlying sensitive issue (abuse) during the follow-up consultation and could benefit from further in-depth training in effective communication skills.
