All mothers and newborns deserve competent care and continuous support during the intrapartum period (Tinker et al., 2006:269). According to the Saving Mothers: Fifth Report on Confidential Enquiries into Maternal Deaths in South Africa, 2008-2010 (SA, 2011:4), the maternal mortality rate (MMR) is 176.22/100 000 live births (SA, 2011:4). The majority of maternal deaths are preventable and have many common preventable factors which are mostly related to the knowledge and skills of the healthcare providers and the challenges within the health care system (SA, 2011:5). The research was conducted in an attempt to make a meaningful contribution to the body of knowledge, specifically knowledge related to the experiences of women regarding the quality intrapartum care in a public hospital in Gauteng Province, and to make recommendations to enhance the quality of intrapartum care. A qualitative study design was used and data collected with the use of individual in-depth interviews. Purposive sampling was used to select participants who represent the target population. The sample used for the study included all women who had given birth within 24 hours before the interviews by normal vaginal delivery. A pilot study was conducted and the interview schedule was finalised. Sixteen individual in-depth interviews were done until data saturation had been achieved. Trustworthiness was ensured according to the principles of credibility, transferability, dependability and confirmability. A digital voice recorder was used to capture data and the data were transcribed verbatim. Field notes were written down for each interview. Data analysis was done by means of content analysis by the researcher and an independent co-coder. Themes and sub-themes were identified. The findings indicated that most of the women‟s experiences were positive regarding the quality of intrapartum care while a lesser percentage had had negative experiences. Identified areas of concern are staff attitudes, communication and staff shortages. Conclusions drawn are that women‟s experiences of quality of intrapartum care were that it is not of the highest standard. There is a need for provision of continuous emotional support during labour, improvement of staff attitudes and promotion of rooming-in, and a need not to be separated from their babies for long periods of time The research concluded with the researcher‟s recommendations for policy, nursing practice, nursing research and nursing education, for the enhancement and adherence of midwives to recommendations in improving the quality of intrapartum care in public hospitals. / MCur, North-West University, Potchefstroom Campus, 2014

Approximately 500,000 women in the US suffer from postpartum depression (PPD) every year. Yet only half of women affected seek treatment. PPD affects the entire family unit, altering parenting behaviors and increasing prevalence of depression among male partners of women suffering from PPD. In addition, infants whose mothers suffer from PPD have a higher risk of Sudden Infant Death Syndrome (SIDS) and more frequent hospitalization as well as cognitive and behavioral delays. Despite the significance of PPD to the health of women and families, most research has focused on the identification and treatment of PPD. Research pertaining to intrapartum events as possible risk factors for PPD has been contradictory and variable in quality. The purpose of this study is to examine possible relationships between intrapartum events and subsequent incidence of postpartum depression.The Diathesis-Stress Model provides the foundation for this proposed research, in which a combination of vulnerability factors (diatheses) in the context of life events (stress) results in psychopathology (PPD). Vulnerability factors such as previous history of depression, prenatal anxiety, or low self esteem may interact with intrapartum stressors such as cesarean section, induction of labor, or use of pain medication to increase PPD symptomatology. This study will examine the stress component of the Diathesis-Stress Model.The study design was a retrospective descriptive design aimed at identifying relationships between intrapartum events and PPD. A chart review was performed to identify intrapartum events and scores on the Edinburgh Postnatal Depression Scale (EPDS) at two- and six- weeks postpartum. The sample consisted of 102 women who delivered at a specified rural New England birthing center during 2007.Nurses commonly interface with women in health care settings and are uniquely poised to educate them about PPD. Nurses have the unique opportunity to alert women to the potential risk for PPD and encourage them to report signs and symptoms early. Increased reporting of symptoms can reduce the number of unidentified cases and promote interventions that avert some of the devastating emotional, physical, and economic consequences.

Midwives are often the lead providers of maternity care for women. To provide the variety of care required by women, they need to be confident in their role and practice. To date, only limited evidence exists in relation to confidence as experienced by midwives. This thesis aims to explore the phenomena of confidence through the lived experience of midwives. In particular, this will encompass confidence in the context of the intrapartum care setting. The theoretical basis for the study was hermeneutic phenomenology, guided by the work of Heidegger and Gadamer. Midwives were recruited from three clinical settings to obtain a diversity of views and experiences. Rich data from diaries and in-depth interviews, from twelve participants, provided insight into the phenomena of confidence and the factors midwives encountered that affected their confidence. The phenomena of confidence consisted of a dynamic balance, between the cognitive and affective elements of knowledge, experience and emotion. This balance was fragile and easily lost, leading to a loss of confidence. Confidence was viewed as vital to midwifery practice by the participants of the study; however, maintaining their confidence was often likened to a battle. A number of cultural and contextual factors were identified as affecting confidence within the working environment, including trust, collegial relationships and organisational influences. Midwives also described various coping strategies they utilised to maintain their confidence in the workplace environment. This study provides unique insight into the phenomena of confidence for midwives working in intrapartum care, resulting in a number of recommendations. These highlight the importance of leadership, education and support for midwives in the clinical environment in enabling them to develop and maintain confidence in practice.

Obesity is a steadily growing problem, and has both physiological and psychological consequences during pregnancy. Obese women may face discrimination which could shape their perceptions of maternity care. To date, few studies have studied the influence of body weight on patient satisfaction with care. The objectives of this study were: (1) to compare childbirth experiences and satisfaction with intrapartum care of normal weight (BMI between 18.5 and 24.9 kg/m2) and obese (BMI greater than or equal to 30.0 kg/m2) women and (2) to determine factors associated with satisfaction with intrapartum care. Guided by Barker’s (1997) pragmatic model of patient satisfaction, a descriptive comparative and correlational design was used to examine the relationship between childbirth experiences, weight discrimination, and satisfaction with intrapartum care among normal weight and obese women. Postpartum primiparous women (N = 138) in two Winnipeg hospitals completed a questionnaire package and had their chart reviewed (70 normal weight, 68 obese weight). Results: Using independent t-test, no significant differences in satisfaction with intrapartum care or childbirth experiences were found in the two weight groups. In the linear multiple regression model, perceived weight discrimination during labour and delivery was negatively associated (β = -5.78, p = 0.032), while professional support (β = 13.11, p < .001) and perceived control and safety (β = 3.25, p = 0.032) were positively associated with satisfaction with intrapartum care. Understanding factors that influence satisfaction with intrapartum care will assist healthcare providers and administrators to improve satisfaction in all women regardless of their weight. / May 2016

This Thesis compares CTG classification techniques proposed in the literature and their potential extensions. A comparison between four classifiers previously assessed - Adaboost, Artificial Neural Networks (ANN), Random Forest (RF), Support Vector Machine (SVM) - and two proposed classifiers - Bayesian ANN (BANN), Relevance Vector Machine - was conducted using a database of 7,568 cases and two open source databases. The Random Forest (RF) achieved the highest average result and was proposed as a benchmark classifier. The proposal to use model certainty to introduce a third, unclassified, class was investigated using the BANN. An increase in the classification accuracy was demonstrated, however the proportion of cases in the unclassified class was too great to be of practical value. The information content of time series was explored using a Hidden Markov Model (HMM). The average performance of the HMM was comparable with the performance of the benchmark with a smaller distribution across validation folds, demonstrating that time-series information provides more stable estimates of class than stationary methods. Finally a method of system identification was implemented. Significant differences between feature trends and histograms in low pH (&LT; 7.1) and healthy pH (&ge; 7.1) cases were observed. These features were used as classifier inputs, and achieved performance similar to existing feature sets. When these features were aligned according the onset of stage 2 labour three unique trend patterns were discovered.

ABSTRACT Cephalopelvic disproportion (CPD) is a common and serious obstetric condition, especially in sub-Saharan Africa. Recognition relies on clinical observations, such as cervical dilatation, head descent, moulding, and size of fetus, all made in a trial of labour. No prospective studies have investigated intrapartum clinical observations and their predictive value for CPD. The objectives of this research were 1) to determine the association of intrapartum clinical findings, especially level of head and moulding, with the outcome of CPD, 2) to determine inter-observer agreement of these findings between clinicians, and 3) to compare intrapartum clinical palpation with symphysis-fundal height (SFH) measurement in the prediction of birth weight. A prospective cross-sectional comparative study was done in the Chris Hani Baragwanath labour ward, a large referral centre. The subjects were women at term, in the active phase of labour, with vertex presentations. The author, blinded to previous clinical or ultrasound findings, performed clinical assessments at the same time as the women’s attending clinicians. His observations were not divulged to the clinicians and he did not participate in obstetric management of the women. The primary outcome measures were CPD, defined as caesarean section for poor progress, and birth weight. Five hundred and eight women were examined, of whom 113 (22.2%) had CPD. Multivariate analysis identified short maternal stature, increased SFH, lesser cervical dilatation, long duration of labour, high degree of parieto-parietal moulding, and high degree of caput succedaneum as independent predictors for CPD. Fetal position and occipito-parietal moulding were not predictive, and level of head, by fifths and by station, was poorly predictive. Inter-observer agreement between the author and attending clinicians was moderate for cervical dilatation, engagement of the head in fifths, and caput succedaneum, and poor for engagement of the head by station. SFH measurement was a slightly better predictor of birth weight than clinical fetal weight estimation. The clinical observations that were shown to be predictive for CPD may be useful adjuncts in the management of a trial of labour. Inter-observer agreement of these findings is at best moderate. Measurement of SFH deserves more attention as an intrapartum predictor of birth weight.

There is uncertainty regarding how much intravenous fluid should be given to women in the intrapartum period. There are no published protocols or guidelines available to address fluid management in labour to optimize care for women and their infants. The absence of an evidence-based approach to intrapartum fluid management may result in fluid overload, with consequent maternal and newborn morbidity. The FILL Trial sought to answer the question, for low risk women receiving epidural analgesia in labour, ‘what is the effect of a conservative protocol for fluid management versus usual care on breastfed newborns’ weight loss prior to hospital discharge? The FILL Trial was a single site randomized controlled trial comparing a conservative protocol of fluid management with usual care for low risk women receiving epidural analgesia in labour. Women in the conservative care group received an IV volume prior to epidural analgesia initiation of < 500 ml and an IV infusion rate of 110 ml per hour. Women in the usual care group received an IV volume prior to epidural analgesia initiation of >500 ml and an IV infusion rate of 200 ml per hour. The primary outcome of interest was the proportion of breastfed infants who lost > 7% of their birth weight prior to discharge. Two hundred women participated, 100 in the conservative care group and 100 in the usual care group. Forty-four infants in the conservative care group and 48 infants in the usual care group lost > 7% of their birth weight, p=0.57. There were no statistically significant differences between groups for breastfeeding outcomes or measures of newborn well being. More babies in the conservative care group required initial admission to the neonatal intensive care unit for septic work up for maternal fever. No septic work ups of the babies yielded positive results. More instrumental vaginal deliveries occurred in the conservative care group. No change in current practice is warranted for intrapartum intravenous fluid volumes < 2500 ml. Future research should focus on the creation of more evidence regarding safe volumes of intravenous fluid during labour.

Maternal and perinatal mortality is one of the biggest challenges to public health, especially in developing countries. South Africa?s health care system is struggling to meet the “health for all” criteria against a backdrop of staff shortages (especially midwives) in an HIV/AIDS epidemic. These factors, together with the economic constraints of a developing country, places great demands on delivering cost–effective, safe, quality intrapartum care that exceeds expectations. The challenge for the manager is to organise the available resources to render the best quality of care cost effectively within the shortest period of time. Various reasons exist for the alarming shortage of nurses and midwives globally and also in South Africa. Unhealthy practice environments are the main cause of the problem as such environments have an impact on the job satisfaction of the midwives as well on patient satisfaction. In the turmoil of the health care system, patients are demanding greater quality of care and are insisting not only on excellent clinical skills, but also on empathetic and personalised care. This research was conducted to make a meaningful contribution to the body of knowledge, specifically knowledge related to quality intrapartum care through the development of a Quality Improvement Intervention Programme (QIIP?). The research was conducted in two phases including five objectives. The first objective gave a theoretical foundation of quality intrapartum care. The second objective included a situational analysis of the resources (personnel and equipment) and determine the quality improvement initiatives that could be implemented for intrapartum care. The third objective determined the practice environment in maternity units at Level 2 hospitals in the North West province that may influence quality intrapartum care. The fourth and last objective of Phase 1 determined the perceptions of management and midwives regarding the facilitating and impeding factors that influence the quality of intrapartum care. From the data that emerged from the first four objectives, specific themes kept repeating themselves, namely structure (what must be in place, e.g. infrastructure and human resources), process (what we do, e.g. life–long learning and implementation of policies) and outcome (the results, e.g. patient satisfaction and a positive practice environment). These collectively contribute to the quality of intrapartum care rendered. Phase 2 consisted of the development of a “Quality Improvement Intervention Programme (QIIP?)” for intrapartum care. In this phase the data from the first four objectives were used to develop the QIIP?. The QIIP? will be marketed as an accreditation tool for maternity units to measure themselves against the best in the world. Qualifying for QIIP? accreditation means improving the quality of intrapartum care resulting in satisfied patients, the establishment of a positive practice environment and a decrease in the Maternal Mortality Rate (MMR). / Thesis (Ph.D. (Nursing))--North-West University, Potchefstroom Campus, 2011.
