Evidence-based prescribing of drugs for secondary prevention of acute coronary syndrome in Aboriginal and non-Aboriginal patients admitted to Western Australian hospitals.

AIMS: To assess the level of evidence-based drug prescribing for acute coronary syndrome (ACS) at discharge from Western Australian (WA) hospitals and determine predictors of such prescribing in Aboriginal and non-Aboriginal patients. METHODS: All Aboriginal (2002-2004) and a random sample of non-Aboriginal (2003) hospital admissions with a principal diagnosis of ACS were extracted from the WA Hospital Morbidity Data Collection of WA Data Linkage System. Clinical information, history of co-morbidities and drugs were collected from medical notes by trained data collectors. Evidence-based prescribing (EBP) was defined as prescribing of aspirin, statin and beta-blocker or angiotensin-converting enzyme inhibitor/angiotensin II antagonist. RESULTS: Records for 1717 ACS patients discharged alive from hospitals were reviewed. The majority of patients (71%) had EBP, and there was no significant difference between Aboriginal and non-Aboriginal patients (70% vs 71%, P = 0.36). Conversely, a significantly higher proportion of Aboriginal patients had none of the drugs prescribed compared with non-Aboriginal patients (11% vs 7%, P < 0.01). EBP for ACS was independently associated with male sex (odds ratio (OR) 1.63, 95% confidence interval (CI) 1.26-2.11), previous admission for ACS (OR 1.83, 95% CI 1.39-2.42) and diabetes (OR 1.36, 95% CI 1.04-1.79). However, ACS patients living in regional and remote areas, attending district or private hospitals, or with a history of chronic obstructive pulmonary disease were significantly less likely to have ACS drugs prescribed at discharge. CONCLUSIONS: Opportunity exists to improve prescribing of recommended drugs for ACS patients at discharge from WA hospitals in both Aboriginal and non-Aboriginal patients. Attention regarding pharmaceutical management post-ACS is particularly required for patients from rural and remote areas, and those attending district and private hospitals.

Obstetric complications and psychological well-being: experiences of Bangladeshi women during pregnancy and childbirth.

Women in developing countries experience postnatal depression at rates that are comparable with or higher than those in developed countries. However, their personal experiences during pregnancy and childbirth have received little attention in relation to postnatal depression. In particular, the contribution of obstetric complications to their emotional well-being during the postpartum period is still not clearly understood. This study aimed to (a) describe the pregnancy and childbirth experiences among women in Bangladesh during normal childbirth or obstetric complications and (b) examine the relationship between these experiences and their psychological well-being during the postpartum period. Two groups of women--one group with obstetric complications (n=173) and the other with no obstetric complications (n=373)--were selected from a sample of women enrolled in a community-based study in Matlab, Bangladesh. The experiences during pregnancy and childbirth were assessed in terms of a five-point rating scale from 'severely uncomfortable=1' to 'not uncomfortable at all=5'. The psychological status of the women was assessed using a validated local version of the Edinburgh Postnatal Depression Scale (EPDS) at six weeks postpartum. Categorical data were analyzed using the chi-square test and continuous data by analysis of variance. Women with obstetric complications reported significantly more negative experiences during their recent childbirth [95% confidence interval (CI) 1.36-1.61, p<0.001] compared to those with normal childbirth. There was a significant main effect on emotional well-being due to experiences of pregnancy [F (4,536)=4.96, p=0.001] and experiences of childbirth [F (4,536)=3.29, p=0.01]. The EPDS mean scores for women reporting severe uncomfortable pregnancy and childbirth experiences were significantly higher than those reporting no such problems. After controlling for the background characteristics, postpartum depression was significantly associated with women reporting a negative childbirth experience. Childbirth experiences of women can provide important information on possible cases of postnatal depression.

Magnitude and contributory factors of postnatal depression: a community-based cohort study from a rural subdistrict of Bangladesh.

BACKGROUND: Recent evidence suggests that the prevalence of postnatal depression (PND) is highest in low-income developing countries. This study aimed to estimate the prevalence of PND and its associated risk factors among Bangladeshi women. METHOD: The study was conducted in the Matlab subdistrict of rural Bangladesh. A cohort of 346 women was followed up from late pregnancy to post-partum. Sociodemographic and other related information on risk factors was collected on structured questionnaires by trained interviewers at 34-35 weeks of pregnancy at the woman's home. A validated local language (Bangla) version of the Edinburgh Postnatal Depression Scale (EPDS-B) was used to measure depression status at 34-35 weeks of pregnancy and at 6-8 weeks after delivery. RESULTS: The prevalence of PND was 22% [95% confidence interval (CI) 17.7-26.7%] at 6-8 weeks post-partum. After adjustment in a multivariate logistic model, PND could be predicted by history of past mental illness [odds ratio (OR) 5.6, 95% CI 1.1-27.3], depression in current pregnancy (OR 6.0, 95% CI 3.0-12.0), perinatal death (OR 14.1, 95% CI 2.5-78.0), poor relationship with mother-in-law (OR 3.6, 95% CI 1.1-11.8) and either the husband or the wife leaving home after a domestic quarrel (OR 4.0, 95% CI 1.6-10.2). CONCLUSIONS: The high prevalence of PND in the study was similar to other countries in the South Asian region. The study findings highlight the need for programme managers and policy makers to allocate resources and develop strategies to address PND in Bangladesh.

Pregnancy spacing and maternal morbidity in Matlab, Bangladesh.

OBJECTIVE: The study examines the relationship between pregnancy spacing and seven measures of maternal morbidity in Matlab, Bangladesh. METHOD: The study analyzes maternal morbidity data on 11,122 women who visited a health center during their third trimester of pregnancy between 1996 and 2002. Adjusted odds ratios were obtained through logistic regression analysis to assess the effects of pregnancy intervals of differing lengths while holding constant other influences (six variables) on maternal morbidity. RESULTS: After controlling these variables, pre-eclampsia and high blood pressure are significantly more likely for women with preceding inter-pregnancy intervals of less than 6 months or 75 months or more compared to those with intervals of 27-50 months. Premature rupture of membranes is significantly more likely following inter-pregnancy intervals of 6-14 months, and edema is significantly more likely following inter-pregnancy intervals over 50 months. CONCLUSION: Short and long inter-pregnancy intervals are associated with increased incidence of some maternal morbidities.

Local production of anti-vibrio cholerae mucosal antibody in reproductive tract tissues after cholera.

To investigate whether intestinal presentation of an antigen by Vibrio cholerae, a noninvasive organism, could induce an anatomically distant mucosal immune response in reproductive tract tissues, the endocervical immune responses of women in Bangladesh were evaluated after cholera. Endocervical secretions were analyzed for secretory IgA (sIgA) antibody against the B subunit of cholera toxin (CtxB) in 9 women with cholera and 8 women with diarrhea caused by neither V. cholerae nor heat labile enterotoxin-producing Escherichia coli. Women infected with V. cholerae developed significant sIgA anti-CtxB responses in endocervical samples (P< or =.02). Antibody subtype analysis of endocervical IgA was consistent with local mucosal production (P< or =.001). Women with cholera did not develop sIgA anti-CtxB responses in serum. The ability to generate specific mucosal immune responses in reproductive tract tissues after intestinal presentation of antigen could facilitate development of vaccines effective against reproductive tract pathogens.

Reproductive-tract infections in women in low-income, low-prevalence situations: assessment of syndromic management in Matlab, Bangladesh.

BACKGROUND: In the control of reproductive-tract infections, including sexually transmitted infections (STIs), in low-income and middle-income countries, WHO recommends syndromic management for individuals with symptoms. This intervention was initially developed in areas where prevalence of such infections is high. We investigated the clinical effectiveness and cost of this approach among a group of women with a low prevalence of infection. METHODS: During a 5-month period, we investigated all women complaining of abnormal vaginal discharge and seeking care at maternal and child health/family-planning centres in Matlab, Bangladesh, for the presence of laboratory-diagnosed reproductive-tract infections and STIs. Syndromic diagnoses made by trained health-care workers were compared with laboratory diagnosis of infection. We then calculated the costs of treating women by means of the recommended WHO algorithm and an adapted algorithm incorporating use of a speculum and simple diagnostic tests. FINDINGS: The prevalence of endogenous infections among 320 women seen was 30%. Cervical infections (Neisseria gonorrhoeae and Chlamydia trachomatis) were found in only three women. The WHO algorithm had a high sensitivity (100%) but a low specificity (zero for bacterial vaginosis, candida, and Trichomonas vaginalis). The speculum-based algorithm had a low sensitivity (between zero and 59%) but a higher specificity (79-97%). Between 36% and 87% of costs would have been spent on uninfected women. INTERPRETATION: The high rate of overtreatment in the population studied carries both financial and social costs--the latter in potentially exposing women misdiagnosed as having an STI to threats of domestic disruption or even violence. We make recommendations for management programmes in areas of low STI prevalence and low income.

PIP: This paper presents a study on the syndromic management of reproductive tract infections among women in low-income and low-prevalence situations. Women complaining of abnormal vaginal discharge and seeking care at health centers in Matlab, Bangladesh, were examined for the presence of laboratory-diagnosed reproductive tract infections and sexually transmitted infections. In the results, 30% of 320 women were diagnosed as having endogenous infections. Overall result of the study revealed a low prevalence of sexually transmitted infections among these women. The WHO algorithm had 100% sensitivity but a low specificity, while the speculum-based algorithm had a low sensitivity (0-59%) but a higher specificity (79-97%). Cost analysis indicated that 87% of expenditure was wasted on overtreatment under the WHO algorithm, while only 36% of expenditure was wasted on overtreatment using the speculum-based algorithm. In conclusion, the development of simple, affordable and effective diagnostic tests should be prioritized by policymakers and public health specialists to ensure the provision of adequate services among the higher risk groups in society.
