Illness recognition and appropriate care seeking for newborn complications in rural Oromia and Amhara regional states of Ethiopia.

BACKGROUND: Ethiopia has made significant progress in reducing child mortality but newborn mortality has stagnated at around 29 deaths per 1000 births. The Maternal Health in Ethiopia Partnership (MaNHEP) was a 3.5-year implementation project aimed at developing a community-oriented model of maternal and newborn health in rural Ethiopia and to position it for scale up. In 2014, we conducted a case study of the project focusing on recognition of and timely biomedical care seeking for maternal and newborn complications. In this paper, we detail the main findings from one component of the case study - the narrative interviews on newborn complications. METHODS: The study area, comprised of six districts in which MaNHEP had been implemented, was located in the two most populous federal regions of Ethiopia, Oromia and Amhara. The final purposive sample consisted of 16 cases in which the newborn survived to 28 days of life, and 13 cases in which the newborn died within 28 days of life, for a total sample size of 29 cases. Narrative interview were conducted with the main caregiver and several witnesses to the event. Analysis of the data included thematic content analysis and the determination of care seeking pathways and levels and timeliness of biomedical care seeking. RESULTS: Mothers and other witnesses do recognize certain symptoms of newborn illness which they often mentioned in clusters. The majority considered the symptoms to be serious and in some case hopeless. Perceived causes were mostly natural. Forty-one percent of care seekers sought timely biomedical care in the neonatal period. Surprisingly, perceived severity did not necessarily trigger care seeking. Facilitators of biomedical care seeking included accessibility of health facilities and counseling by health workers, whereas barriers included perceived vulnerability of newborns, post-partum restrictions on movements, hopelessness, wait-and-see atttitudes, poor communication and physical inaccessibility of health facilities. CONCLUSIONS: Symptom recognition and care seeking patterns indicate the need to strengthen focused locally relevant health messages which target mothers, fathers and other community members, to further enhance access to health care and to improve referral and quality of care.

Traditional birth attendant training for improving health behaviours and pregnancy outcomes.

BACKGROUND: Between the 1970s and 1990s, the World Health Organization promoted traditional birth attendant (TBA) training as one strategy to reduce maternal and neonatal mortality. To date, evidence in support of TBA training remains limited and conflicting. OBJECTIVES: To assess effects of TBA training on health behaviours and pregnancy outcomes. SEARCH STRATEGY: We searched the Trials Registers of the Cochrane Pregnancy and Childbirth Group and Cochrane Effective Practice and Organisation of Care Group (EPOC) (June 2006); electronic databases representing fields of education, social, and health sciences (inception to June 2006); the internet; and contacted experts. SELECTION CRITERIA: Published and unpublished randomized controlled trials (RCT), controlled before/after and interrupted time series studies comparing trained and untrained TBAs or women cared for/living in areas served by TBAs. DATA COLLECTION AND ANALYSIS: Three authors independently assessed study quality and extracted data. MAIN RESULTS: Four studies, involving over 2000 TBAs and nearly 27,000 women, are included. One cluster-randomized trial found significantly lower rates in the intervention group regarding stillbirths (adjusted OR 0.69, 95% confidence interval (CI) 0.57 to 0.83, P < 0.001), perinatal death rate (adjusted OR 0.70, 95% CI 0.59 to 0.83, P < 0.001) and neonatal death rate (adjusted OR 0.71, 95% CI 0.61 to 0.82, P < 0.001). Maternal death rate was lower but not significant (adjusted OR 0.74, 95% CI 0.45 to 1.22, P = 0.24) while referral rates were significantly higher (adjusted OR 1.50, 95% CI 1.18 to 1.90, P < 0.001). A controlled before/after study among women who were referred to a health service found perinatal deaths decreased in both intervention and control groups with no significant difference between groups (OR 1.02, 95% CI 0.59 to 1.76, P = 0.95). Similarly, the mean number of monthly referrals did not differ between groups (P = 0.321). One RCT found a significant difference in advice about introduction of complementary foods (OR 2.07, 95% CI 1.10 to 3.90, P = 0.02) but no significant difference for immediate feeding of colostrum (OR 1.37, 95% CI 0.62 to 3.03, P = 0.44). Another RCT found no significant differences in frequency of postpartum haemorrhage (OR 0.94, 95% CI 0.76 to 1.17, P = 0.60) among women cared for by trained versus TBAs. AUTHORS' CONCLUSIONS: The potential of TBA training to reduce peri-neonatal mortality is promising when combined with improved health services. However, the number of studies meeting the inclusion criteria is insufficient to provide the evidence base needed to establish training effectiveness.

Contribution of multiple glaucoma medications to visual function and quality of life in patients with glaucoma.

BACKGROUND: Previous studies examining the correlation between medical treatment and overall quality of life in patients with glaucoma assessed differences between a glaucoma population and a matched group (without glaucoma) and were not aimed specifically at detecting a relation between visual acuity, visual field status and medication use, and visual function and quality of life. We performed a study to determine this relation in patients with chronic open-angle glaucoma (COAG). METHODS: The study was cross-sectional. Of 235 English-speaking patients with a diagnosis of COAG, normal-pressure glaucoma or suspected glaucoma (receiving therapy) seen in a university-based glaucoma practice between Feb. 1 and Apr. 30, 1998, 224 (95.3%) agreed to participate. All subjects completed two questionnaires: the Visual Function Assessment and the EQ-5D, assessing health status (quality of life). Visual acuity, diagnosis, age, sex, country of birth, type and number of medications for topical and for oral use, dosage, and history of laser treatment and surgery were extracted from the medical record. Pearson rank correlation and multivariate analyses were performed. RESULTS: On univariate analysis visual function was correlated with age, visual acuity, number of glaucoma medications, number of applications of eyedrops, mean deviation in better eye, mean deviation in worse eye, and lower hemifield involvement in both eyes. On multivariate analysis only visual acuity and visual field status were independently associated with visual function. Univariate analysis showed that health status was correlated with age, visual function and number of medications for oral use; however, age failed to retain statistical significance in the regression analysis. INTERPRETATION: Our results suggest that the number of glaucoma medications is not predictive of quality of life.

Reliability and reproducibility of a Chinese-language visual function assessment.

OBJECTIVE: The purpose of the study was to validate a Chinese-language visual function assessment within the context of a routine cataract surgery practice and to assess the contribution of the method of questionnaire administration. DESIGN: The visual function assessment (VFA) was translated into Chinese. Two groups of study subjects were recruited: Chinese who did not speak English and Chinese conversant in English. Consecutive preoperative cataract patients of Chinese ancestry presenting to an urban ophthalmology practice were recruited. The questionnaire was administered in person or by telephone interview. Pre-operative visual acuity was recorded. Visual function scores were analyzed to assess reliability and correlation with visual acuity. RESULTS: Among the 186 potential study subjects, 155 patients completed the study The Chinese-language visual function assessment had good internal consistency (Cronbach alpha = 0.97, inter-item correlations = 0.43 to 0.96) . Reliability (with regard to the English version) and test-retest reproducibility of the Chinese questionnaire were strong with intraclass correlation coefficients greater than 0.60. The method of administration contributed to the measures of reliability and reproducibility. CONCLUSION: These results show that a Chinese-language version of the VFA questionnaire is reliable and valid. In industrialized countries with large Chinese-speaking populations and newly developed countries of East and Southeast Asia, the visual function assessment may be helpful in assisting routine clinical patient evaluation and cross-cultural outcome assessment programmes. Our findings also suggest that self-administered visual function assessments may be more reliable and valid than interview-generated assessments.

Validity of the visual function index (VF-14) in patients with retinal disease.

OBJECTIVE: To test the validity of the Visual Function Index (VF-14) in patients with retinal disease. DESIGN: A self-administered questionnaire package in association with clinical examination findings. PARTICIPANTS: Consecutive patients attending the Vancouver General Hospital Eye Care Centre, Vancouver, British Columbia, retina clinic between May 1 and August 15, 1998. MAIN OUTCOME MEASURES: Responses to the questionnaire package as they relate to global self-assessment scales and visual acuity. In addition, correlations were calculated between the VF-14, the 36-Item Short-Form Health Survey, a Weighted Comorbidity Scale, and visual acuity scores. RESULT: Five hundred forty-seven patients were given the questionnaire package to complete. The VF-14 demonstrated a moderately strong positive association with patient self-rating of amount of trouble, satisfaction, and overall quality of vision. Correlations between the 36-Item Short-Form Health Survey, visual acuity, and the global scales were mild to moderate. The VF-14 was moderately correlated with visual acuity in the better and the worse eyes. CONCLUSIONS: This study provides support for the validity of the VF-14 as a measure of functional impairment in patients with retinal disease. Once responsiveness has been measured and an analysis of disease subtypes has been carried out, the VF-14 will be ready for inclusion in clinical trials to evaluate patients' functional ability. Further implementation and development of this outcome measure will better our understanding of the utility of the functional assessment format for patients with retinal disease.

Prophylactic scleral buckle for prevention of retinal detachment following vitrectomy for macular hole.

AIM: To review the rate of retinal detachment after macular hole surgery in patients who received vitrectomy and scleral buckle versus those who had vitrectomy alone. METHODS: All patient charts and hospital records were examined for patients who underwent vitrectomy surgery for macular hole between September 1993 and June 1997. A total of 326 patients were identified and all were followed for a minimum of 6 months. Clinical records were examined for details of the surgical procedure, visual acuity, hole closure status, adjuvant therapies used, and postoperative retinal attachment status. Relative risks (the ratio of the incidence rate in the exposed to that in the unexposed) with 95% confidence intervals and chi(2) tests were calculated to determine which variables were associated with retinal detachment. The primary outcome measure in this review was retinal attachment status. RESULTS: Of 326 eyes which underwent surgery for macular hole during the study period, scleral buckles were utilised in 152 (46.6%) patients. Analysis revealed a detachment rate of 13.2% in patients who did not receive a scleral buckle compared with 5.9% detachment rate in those who did. Analysis of these results indicated a 2.42 times greater risk of developing a retinal detachment in patients without a scleral buckle. Complications related to the use of scleral buckles occurred in two of 152 cases (1.3%) CONCLUSIONS: A reduction in the rate of retinal detachment was noted in patients receiving prophylactic scleral buckles. Those finding suggest a possible beneficial effect of this adjunctive procedure in preventing postoperative retinal detachments. The authors are currently preparing a multicentred, prospective, clinical trial to further study this hypothesis

An epidemiologic investigation of unexpected refractive errors following cataract surgery.

OBJECTIVE: To determine the extent and magnitude of unexpected refractive errors following cataract surgery with intraocular lens (IOL) implantation and to determine what characteristics were associated with the errors. DESIGN: In this nonconcurrent prospective study, preoperative, intraoperative and postoperative information was collected from the charts of the 523 consecutive patients who underwent cataract extraction and polymethylmethacrylate IOL implantation performed by one of nine participating surgeons between Jan. 1 and Apr. 30, 1995, or the same dates in 1996. SETTING: University-affiliated eye care centre in Vancouver. OUTCOME MEASURE: Postoperative excess correction, calculated for each patient by subtracting the actual postoperative spherical equivalent from the expected spherical equivalent. Eyes with an excess correction of more than 1.00 dioptre were considered "overcorrected." RESULTS: Univariate analysis showed that the formula used to calculate the lens power, axial length, year of surgery, A-constant/surgeon factor used and lens manufacturer were associated with overcorrection. In a logistic regression model, lens manufacturer was the only variable independently associated with overcorrection. CONCLUSIONS: Routine reporting and follow-up is necessary to identify this kind of "outbreak" and the associated factors. The current guidelines of the Health Protection Branch, Health Canada, for evaluation of IOLs that have changed manufacturers are not adequate to identify the kind of error that we detected.

Obstetric dimensions of the true pelvis in a medieval population from Sudanese Nubia.

Functional analysis of the true pelvis (defined as that portion lying below and including the pelvic brim) was undertaken on a sample of 36 females from the Medieval site of Kulubnarti in Sudanese Nubia. Standard obstetric measurements were taken and compared to four additional prehistoric skeletal samples and to modern American standards for the same obstetric dimensions. Relative to the other prehistoric populations, the Kulubnarti pelves are smaller in most dimensions and, when compared to modern American standards, from one-third to one-half would be diagnosed as contracted in one or more planes. Given the meager, fluctuating resources of these Medieval Nubians' harsh desert environment, pelvic size reduction is a likely result of body size reduction as one biological response to nutritional stress (Mittler and Van Gerven, 1989; Moore et al., 1986; Van Gerven et al., 1981). It is argued, however, that size reduction created a high potential for either maternal-neonatal morbidity and mortality due to fetopelvic disproportion or neonatal loss due to low birth weight. In either case, it is suggested that the Kulubnarti population paid a significant biological price for this aspect of size reduction.
