Development and Pilot Test of a Multi-Component Intervention to Support Women's Recovery from Female Genital Fistula.

INTRODUCTION AND HYPOTHESIS: We evaluated a pilot multi-component reintegration intervention to improve women's physical and psychosocial quality of life after genital fistula surgery. METHODS: Twelve women undergoing fistula repair at Mulago Specialized Women and Neonatal Hospital (Kampala, Uganda) anticipated in a 2-week multi-component intervention including health education, psychosocial therapy, physiotherapy, and economic investment. We assessed feasibility through recruitment, retention, and adherence, acceptability through intervention satisfaction, and preliminary effectiveness through reintegration, mental health, physical health, and economic status. We collected quantitative data at enrollment, 6 weeks, 3 months, and 6 months. We conducted in-depth interviews with six participants. Quantitative data are presented descriptively, and qualitative data analyzed thematically. RESULTS: Participants had a median age of 34.5 years (25.5-38.0), 50% were married/partnered, 42% were separated, 50$ had completed less than primary education, and 67% were unemployed. Mean number of sessions received was 12 for health education (range 5-15), 8 for counseling (range 8-9), and 6 for physiotherapy (range 4-8). Feasibility was demonstrated by study acceptance among all those eligible (100%); comfort with study measures, data collection frequency and approach; and procedural fidelity. Acceptability was high; all participants reported being very satisfied with the intervention and each of the components. Participant narratives echoed quantitative findings and contributed nuanced perspectives to understanding approach and content. CONCLUSIONS: Our results suggest that the intervention and associated research were both feasible and acceptable, and suggested certain modifications to the intervention protocol to reduce participant burden. Further research to determine the effectiveness of the intervention above and beyond surgery alone with regard to the health and well-being of women with fistulas is warranted.

Identifying opportunities for prevention of adverse outcomes following female genital fistula repair: protocol for a mixed-methods study in Uganda.

BACKGROUND: Female genital fistula is a traumatic debilitating injury, frequently caused by prolonged obstructed labor, affecting between 500,000-2 million women in lower-resource settings. Vesicovaginal fistula causes urinary incontinence, and other morbidity may occur during fistula development. Women with fistula are stigmatized, limit social and economic engagement, and experience psychiatric morbidity. Improved surgical access has reduced fistula consequences yet post-repair risks impacting quality of life and well-being include fistula repair breakdown or recurrence and ongoing or changing urine leakage or incontinence. Limited evidence on risk factors contributing to adverse outcomes hinders interventions to mitigate adverse events. This study aims to quantify these adverse risks and inform clinical and counseling interventions to optimize women's health and quality of life following fistula repair through: identifying predictors and characteristics of post-repair fistula breakdown and recurrence (Objective 1) and post-repair incontinence (Objective 2), and to identify feasible and acceptable intervention strategies (Objective 3). METHODS: This mixed-methods study incorporates a prospective cohort of women with successful vesicovaginal fistula repair at approximately 12 fistula repair centers in Uganda (Objectives 1-2) followed by qualitative inquiry among key stakeholders (Objective 3). Cohort participants will have a baseline visit at the time of surgery followed by data collection at 2 weeks, 6 weeks, 3 months and quarterly thereafter for 3 years. Primary predictors to be evaluated include patient-related factors, fistula-related factors, fistula repair-related factors, and post-repair behaviors and exposures, collected via structured questionnaire at all data collection points. Clinical exams will be conducted at baseline, 2 weeks post-surgery, and for outcome confirmation at symptom development. Primary outcomes are fistula repair breakdown or fistula recurrence and post-repair incontinence. In-depth interviews will be conducted with cohort participants (n ~ 40) and other key stakeholders (~ 40 including family, peers, community members and clinical/social service providers) to inform feasibility and acceptability of recommendations. DISCUSSION: Participant recruitment is underway. This study is expected to identify key predictors that can directly improve fistula repair and post-repair programs and women's outcomes, optimizing health and quality of life. Furthermore, our study will create a comprehensive longitudinal dataset capable of supporting broad inquiry into post-fistula repair health. Trial Registration ClinicalTrials.gov Identifier: NCT05437939.

Female genital fistula is a traumatic birth injury which occurs where access to emergency childbirth care is poor. It causes uncontrollable urine leakage and is associated with other physical and psychological symptoms. Due to the urine leakage and its odor, women with fistula are stigmatized which has mental health and economic consequences. Ensuring women's access to fistula surgery and ongoing wellbeing is important for limiting the impact of fistula. After fistula surgery, health risks such as fistula repair breakdown or recurrence or changes to urine leakage can happen, but studies during this time are limited. Our study seeks to measure these health risks and factors influencing these risks quantitatively, and work with patients, community members, and fistula care providers to come up with solutions. We will recruit up to 1000 participants into our study at the time of fistula surgery and follow them for three years. We will collect data on patient sociodemographic characteristics, clinical history, and behavior after fistula repair through patient survey and medical record review. If participants have changes in urine leakage, they will be asked to return to the fistula repair hospital for exam. We will interview about 80 individuals to obtain their ideas for feasible and acceptable intervention options. We expect that this study will help to understand risk factors for poor health following fistula repair and, eventually, improve women's health and quality of life after fistula.

The social, economic, emotional, and physical experiences of caregivers for women with female genital fistula in Uganda: A qualitative study.

ABSTRACTThis study aimed to explore the firsthand experiences of informal primary caregivers of women with female genital fistula in Uganda. Caregivers that accompanied women for surgery at Mulago National Teaching and Referral Hospital were recruited between January and September 2015. Caregivers participated in in-depth interviews and focus groups. Data were analysed thematically and informed adaptation of a conceptual framework. Of 43 caregivers, 84% were female, 95% family members, and most married and formally employed. Caregivers engaged in myriad personal care and household responsibilities, and described being on call for an average of 22.5 h per day. Four overlapping themes emerged highlighting social, economic, emotional, and physical experiences/consequences. The caregiving experience was informed by specific caregiver circumstances (e.g. personal characteristics, care needs of their patient) and dynamic stressors/supports within the caregiver's social context. These results demonstrate that caregivers' lived social, economic, emotional, and physical experiences and consequences are influenced by both social factors and individual characteristics of both the caregiver and their patient. This study may inform programmes and policies that increase caregiving supports while mitigating caregiving stressors to enhance the caregiving experience, and ultimately ensure its feasibility, particularly in settings with constrained resources.

Identifying Opportunities for Prevention of Adverse Outcomes Following Female Genital Fistula Repair: Protocol for a Mixed-Methods Study in Uganda.

Background: Female genital fistula is a traumatic debilitating injury, frequently caused by prolonged obstructed labor, affecting between 500,000-2 million women in lower-resource settings. Vesicovaginal fistula causes urinary incontinence. Other gynecologic, neurologic and orthopedic morbidity may occur during fistula development. Women with fistula are stigmatized; limit engagement in social, economic, or religious activities; and report high psychiatric morbidity. Improved global surgical access has reduced fistula consequences yet post-repair risks impacting quality of life and well-being include fistula repair breakdown or recurrence and ongoing or changing urine leakage or incontinence. Limited evidence on risk factors contributing to adverse outcomes hinders interventions to mitigate adverse events, protecting health and quality of life after surgery. This study seeks to identify predictors and characteristics of post-repair fistula breakdown and recurrence (Aim 1) and post-repair incontinence (Aim 2), and to identify feasible and acceptable intervention strategies (Aim 3). Methods: This mixed-methods study incorporates a prospective cohort study of women with successful vesicovaginal fistula repair at approximately 12 fistula repair centers and affiliated care sites in Uganda (Aims 1-2) followed by qualitative inquiry among key stakeholders (Aim 3). Cohort participants will have a baseline visit at the time of surgery followed by data collection at 2 weeks, 6 weeks, 3 months and quarterly thereafter for 3 years. Primary predictors to be evaluated include patient-related factors, fistula-related factors, fistula repair-related factors, and post-repair behaviors and exposures, collected via structured questionnaire at all data collection points. Clinical exams will be conducted at baseline, 2 weeks post-surgery, and for outcome confirmation at symptom development. Primary outcomes are fistula repair breakdown or fistula recurrence and post-repair incontinence. In-depth interviews will be conducted with cohort participants (n ~ 40) and other key stakeholders (~ 40 including family, peers, community members and clinical/social service providers) to develop feasible and acceptable intervention concepts for adjustment of identified risk factors. Discussion: Participant recruitment is underway. This study is expected to identify key predictors that can directly improve fistula repair and post-repair programs and women's outcomes, optimizing health and quality of life. Furthermore, our study will create a comprehensive longitudinal dataset capable of supporting broad inquiry into post-fistula repair health.

Maternal and umbilical cord blood lactate for predicting perinatal death: a secondary analysis of data from a randomized controlled trial.

BACKGROUND: In high resource settings, lactate and pH levels measured from fetal scalp and umbilical cord blood are widely used as predictors of perinatal mortality. However, the same is not true in low resource settings, where much of perinatal mortality occurs. The scalability of this practice has been hindered by difficulty in collecting fetal scalp and umbilical blood sample. Little is known about the use of alternatives such as maternal blood, which is easier and safer to obtain. Therefore, we aimed to compare maternal and umbilical cord blood lactate levels for predicting perinatal deaths. METHODS: This was secondary analysis of data from a randomized controlled trial assessing the effect of sodium bicarbonate on maternal and perinatal outcomes among women with obstructed labour at Mbale regional referral hospital in Eastern Uganda. Lactate concentration in maternal capillary, myometrial, umbilical venous and arterial blood was measured at the bedside using a lactate Pro 2 device (Akray, Japan Shiga) upon diagnosis of obstructed labour. We constructed Receiver Operating Characteristic curves to compare the predictive ability of maternal and umbilical cord lactate and the optimal cutoffs calculated basing on the maximal Youden and Liu indices. RESULTS: Perinatal mortality risk was: 102.2 deaths per 1,000 live births: 95% CI (78.1-130.6). The areas under the ROC curves were 0.86 for umbilical arterial lactate, 0.71 for umbilical venous lactate, and 0.65 for myometrial lactate, 0.59 for maternal lactate baseline, and 0.65 at1hr after administration of bicarbonate. The optimal cutoffs for predicting perinatal death were 15 0.85 mmol/L for umbilical arterial lactate, 10.15mmol/L for umbilical venous lactate, 8.75mmol/L for myometrial lactate, and 3.95mmol/L for maternal lactate at recruitment and 7.35mmol/L after 1 h. CONCLUSION: Maternal lactate was a poor predictor of perinatal death, but umbilical artery lactate has a high predictive value. There is need for future studies on the utility of amniotic fluid in predicting intrapartum perinatal deaths.

Women's sexual activity and experiences following female genital fistula surgery.

BACKGROUND: Surgical repair has a transformative impact on the lives of women affected by female genital fistula; however, various physical, social, and economic challenges may persist postrepair and prevent complete reengagement in relationships and communities. Nuanced investigation of these experiences is needed to inform programming that aligns with women's reintegration needs. AIM: We investigated the sexual activity resumption, experiences, and concerns of women in Uganda during the year following genital fistula repair surgery. METHODS: Women were recruited from Mulago Hospital between December 2014 and June 2015. We collected data at baseline and 4 times postsurgery about sociodemographic characteristics and physical/psychosocial status; we also assessed sexual interest and satisfaction twice. We performed in-depth interviews with a subset of participants. We analyzed quantitative findings via univariate analyses, and qualitative findings were coded and analyzed thematically. OUTCOMES: We assessed sexual readiness, fears, and challenges following surgical repair of female genital fistula using quantitative and qualitative measures of sexual activity, pain with sex, sexual interest/disinterest, and sexual satisfaction/dissatisfaction. RESULTS: Among the 60 participants, 18% were sexually active at baseline, which decreased to 7% postsurgery and increased to 55% at 1 year after repair. Dyspareunia was reported by 27% at baseline and 10% at 1 year; few described leakage during sex or vaginal dryness. Qualitative findings showed wide variance of sexual experiences. Some reported sexual readiness quickly after surgery, and some were not ready after 1 year. For all, fears included fistula recurrence and unwanted pregnancy. CONCLUSION: These findings suggest that postrepair sexual experiences vary widely and intersect meaningfully with marital and social roles following fistula and repair. In addition to physical repair, ongoing psychosocial support is needed for comprehensive reintegration and the restoration of desired sexuality.

Feasibility and acceptability of mobile phone data collection for longitudinal follow-up among patients treated for obstetric fistula in Uganda.

Rapid dissemination of mobile technology provides substantial opportunity for overcoming challenges reaching rural and marginalized populations. We assessed feasibility and acceptability of longitudinal mobile data capture among women undergoing fistula surgery in Uganda (n = 60) in 2014-2015. Participants were followed for 12 months following surgery, with data captured quarterly, followed by interviews at 12 months. Participant retention was high (97%). Most respondents reported no difficulty with mobile data capture (range 93%-100%), and preferred mobile interview (88%-100%). Mobile data capture saved 1000 person-hours of transit and organizational time. Phone-based mobile data collection provided social support. Our results support this method for longitudinal studies among geographically and socially marginalized populations.

Incidence and determinants of perinatal mortality among women with obstructed labour in eastern Uganda: a prospective cohort study.

BACKGROUND: In Uganda, the incidence and determinants of perinatal death in obstructed labour are not well documented. We determined the incidence and determinants of perinatal mortality among women with obstructed labour in Eastern Uganda. METHODS: Between July 2018 and September 2019, 584 with obstructed labour were recruited and followed up to the 7th day postnatal. Information on maternal characteristics, obstetric factors and laboratory parameters was collected. Each patient received the standard perioperative care. We used a generalized linear model for the Poisson family, with a log link and robust variance estimation to determine the association between the exposure variables and perinatal death. RESULTS: Of the 623 women diagnosed with obstructed labour, 584 met the eligibility criteria. There were 24 fresh still births (FSB) and 32 early neonatal deaths (ENND) giving an FSB rate of 43.8 (95% CI 28.3-64.4) deaths per 1000 total births; early neonatal death rate of 58.4 (95% CI 40.3-81.4) deaths per 1000 and an overall perinatal mortality rate of 102.2 (95% CI 79.4-130.6) deaths in the first 7 days of life. A mother being referred in active labour adjusted risk ratio of 2.84 (95% CI: 1.35-5.96) and having high blood lactate levels at recruitment adjusted risk ratio 2.71 (95% CI: 1.26-4.24) were the determinants of perinatal deaths. CONCLUSIONS: The incidence of perinatal death was four times the regional and national average. Babies to women referred in active labour and those with high maternal blood lactate were more likely to die.

Effect of pre-operative bicarbonate infusion on maternal and perinatal outcomes among women with obstructed labour in Mbale hospital: A double blind randomized controlled trial.

INTRODUCTION: Oral bicarbonate solution is known to improve both maternal and perinatal outcomes among women with abnormal labour (dystocia). Its effectiveness and safety among women with obstructed labour is not known. OBJECTIVE: To determine the effect and safety of a single-dose preoperative infusion of sodium bicarbonate on maternal and fetal blood lactate and clinical outcomes among women with obstructed labour (OL) in Mbale hospital. METHODS: We conducted a double blind, randomised controlled trial from July 2018 to September 2019. The participants were women with OL at term (≥37 weeks gestation), carrying a singleton pregnancy with no other obstetric emergency, medical comorbidity or laboratory derangements. INTERVENTION: A total of 477 women with OL were randomized to receive 50ml of 8.4% sodium bicarbonate (238 women) or 50 mL of 0.9% sodium chloride (239 women). In both the intervention and controls arms, each participant was preoperatively given a single dose intravenous bolus. Every participant received 1.5 L of normal saline in one hour as part of standard preoperative care. OUTCOME MEASURES: Our primary outcome was the mean difference in maternal venous blood lactate at one hour between the two arms. The secondary outcomes were umbilical cord blood lactate levels at birth, neonatal sepsis and early neonatal death upto 7 days postnatal, as well as the side effects of sodium bicarbonate, primary postpartum hemorrhage, maternal sepsis and mortality at 14 days postpartum. RESULTS: The median maternal venous lactate was 6.4 (IQR 3.3-12.3) in the intervention and 7.5 (IQR 4.0-15.8) in the control group, with a statistically non-significant median difference of 1.2 mmol/L; p-value = 0.087. Vargha and Delaney effect size was 0.46 (95% CI 0.40-0.51) implying very little if any effect at all. CONCLUSION: The 4.2g of preoperative intravenous sodium bicarbonate was safe but made little or no difference on blood lactate levels. TRIAL REGISTRATION: PACTR201805003364421.

Validation of an adapted instrument to measure female genital fistula-related stigma.

Female genital fistula results in severe physical, psychological, and social sequelae. Qualitative research confirms stigma pervasiveness; however, no quantitative instrument exists to measure fistula-related stigma. We adapted an existing HIV-related stigma instrument to fistula-related stigma and assessed its reliability and validity. We recruited 60 Ugandan women seeking genital fistula surgery (December 2014-June 2015). We used exploratory factor analysis to explore the scale's latent structure and evaluated internal consistency reliability with Raykov's ρ statistic. We assessed construct validity through linear regression of stigma with quality of life, depressive symptoms and self-esteem. We retained 15 items across factors 'enacted stigma' and 'internalised stigma' (ρ = 0.960 and ρ = 0.748, respectively). Stigma was inversely associated with all quality of life domains; effect sizes were largest for environmental (enacted stigma, 0.69-point reduction) and psychological (internalised stigma, 0.67-point reduction) domains. Both stigma domains were associated positively with depressive symptoms and inversely with self-esteem, with 0.75 and 1.05-point increases in depressive symptoms and 0.45 and 0.77-point decreases in self-esteem for enacted and internalised stigma, respectively. Results suggest the reliability and validity of the adapted fistula stigma instrument. This instrument may help us understand stigma levels, compare stigma across individuals and communities, prioritise stigma-reduction strategies, and assess intervention impact.

Risk factors for obstructed labour in Eastern Uganda: A case control study.

INTRODUCTION: Obstructed labour (OL) is an important clinical and public health problem because of the associated maternal and perinatal morbidity and mortality. Risk factors for OL and its associated obstetric squeal are usually context specific. No epidemiological study has documented the risk factors for OL in Eastern Uganda. This study was conducted to identify the risk factors for OL in Mbale Hospital. OBJECTIVE: To identify the risk factors for OL in Mbale Regional Referral and Teaching Hospital, Eastern Uganda. METHODS: We conducted a case control study with 270 cases of women with OL and 270 controls of women without OL. We consecutively enrolled eligible cases between July 2018 and February 2019. For each case, we randomly selected one eligible control admitted in the same 24-hour period. Data was collected using face-to-face interviews and a review of patient notes. Logistic regression was used to identify the risk factors for OL. RESULTS: The risk factors for OL were, being a referral from a lower health facility (AOR 6.80, 95% CI: 4.20-11.00), prime parity (AOR 2.15 95% CI: 1.26-3.66) and use of herbal medicines in active labour (AOR 2.72 95% CI: 1.49-4.96). Married participants (AOR 0.59 95% CI: 0.35-0.97) with a delivery plan (AOR 0.56 95% CI: 0.35-0.90) and educated partners (AOR 0.57 95% CI: 0.33-0.98) were less likely to have OL. In the adjusted analysis, there was no association between four or more ANC visits and OL, adjusted odds ratio [(AOR) 0.96 95% CI: 0.57-1.63)]. CONCLUSIONS: Prime parity, use of herbal medicines in labour and being a referral from a lower health facility were identified as risk factors. Being married with a delivery plan and an educated partner were protective of OL. Increased frequency of ANC attendance was not protective against obstructed labour.

Rehabilitation and reintegration programming adjunct to female genital fistula surgery: A systematic scoping review.

BACKGROUND: Female genital fistula is associated with significant physical, psychological, and economic consequences; however, a knowledge and practice gap exists around services adjunct to fistula surgery. OBJECTIVES: To examine rehabilitation and reintegration services provided adjunct to genital fistula surgery, map existing programming and outcomes, and identify areas for additional research. SEARCH STRATEGY: We searched the published and grey literature from January 2000 to June 2019. Two reviewers screened articles and extracted data using standardized methods. SELECTION CRITERIA: Research and programmatic articles describing service provision in addition to female genital fistula surgery were included. DATA COLLECTION AND ANALYSIS: Of 3047 published articles and 2623 unpublished documents identified, 26 and 55, respectively, were analyzed. MAIN RESULTS: Programming identified included combinations of health education, physical therapy, social support, psychosocial counseling, and economic empowerment, largely in sub-Saharan Africa. Improvements were noted in physical and psychosocial health. CONCLUSIONS: Existing literature supports holistic fistula care through adjunct reintegration programming. Improving the evidence base requires implementing robust study designs, increasing reporting detail, and standardizing outcomes across studies. Increased financing for holistic fistula care is critical for developing and supporting programming to ensure positive outcomes.

Perceived Causes of Obstetric Fistula and Predictors of Treatment Seeking among Ugandan Women: Insights from Qualitative Research.

Many obstetric fistula patients remain untreated or present late to treatment despite increasing surgical availability in Uga nda. We explored women's perceptions of the cause of their obstetric fistula and their treatment seeking behaviours, including barriers and facilitators to timely care access. In-depth interviews and focus group discussions were conducted from June-August 2014 among 33 women treated for obstetric fistula at Mulago Hospital, Kampala. Data were analysed to describe dimensions and commonalities of themes identified under perceived causes and treatment seeking experiences, and their intersection. Perceived obstetric fistula causes included delays in deciding on hospital delivery, lengthy labour, injury caused by the baby, health worker incompetence, and traditional beliefs. Treatment seeking timing varied. Early treatment seeking was facilitated by awareness of treatment availability through referral, the media, community members, and support by partners and children. Barriers to early treatment seeking included inadequate financial and social support, erroneous perceptions about fistula causes and curability, incorrect diagnoses, and delayed or lack of care at health facilities. Our study supports broad educational and awareness activities, facilitation of social and financial support for accessing care, and improving the quality of emergency obstetric care and fistula treatment surgical capacity to reduce women's suffering.

Women's experiences of fistula-related stigma in Uganda: a conceptual framework to inform stigma-reduction interventions.

Fistula-related stigma is common. The absence of a unifying conceptual framework prevents a nuanced understanding of the nature of fistula-related stigma, comparison across contexts and the ability to contrast with other stigmas. It also hinders intervention development. We conducted in-depth interviews or focus groups with 60 women who had undergone fistula surgery 6-24 months prior at Mulago Hospital in Kampala, Uganda in 2014. Transcripts were analysed for experiences and consequences of enacted, anticipated and internalised stigma. Narratives revealed experiences with enacted stigma, including gossip, verbal abuse and social exclusion. Women also anticipated and feared stigma in the future. Internalised stigma reports revealed shame and low self-esteem: self-worth reduction, feeling disgraced and envisioning no future. Consequences included social isolation, changes to normal activities, non-disclosure and poor mental health. Refining stigma theory to specific conditions has resulted in a more nuanced understanding of stigma dimensions, manifestations, mechanisms and consequences, permitting comparison across contexts and populations and the development of stigma-reduction interventions. These lessons should be applied to fistula, acknowledging unique features: concealability, the potential for treatment, lack of community awareness and the social consequences of stillbirth. Reducing fistula-related stigma requires timely surgery and supportive care, stigma-reduction interventions and addressing the complex societal structures that perpetuate fistula.

Rehabilitation and reintegration programming adjunct to female genital fistula surgery: a scoping review protocol.

INTRODUCTION: Female genital fistula is a debilitating traumatic injury, largely birth-associated, globally affecting up to 2 million women, mostly in sub-Saharan Africa. Fistula has significant physical, psychological and economic consequences. Women often face challenges in reintegrating and resuming prior roles despite successful surgery. Synthesising the evidence on services adjunct to fistula surgery and their outcomes is important for developing the evidence base for best practices and identifying research priorities. This scoping review seeks to examine the range of rehabilitation and reintegration services provided as adjunct to genital fistula surgery, map the existing programming and outcomes, and identify areas for additional research. METHODS AND ANALYSIS: Our scoping review is informed by existing methodological frameworks and will be conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses-ScR guidelines. The search strategy will be applied to nine biomedical, public health and social science databases. The initial search was completed on 27 September 2018. Grey literature will be identified through targeted Google searches and from organisational websites identified as relevant by the United Nations Population Fund (UNFPA) Campaign to End Fistula. We will iteratively build our search strategy through term harvesting and review, and search reference lists of reports and articles to identify additional studies. Two reviewers will independently screen titles and abstracts, followed by full-text screening of all potentially relevant articles and standardised data extraction. Articles eligible for inclusion will discuss research or programmatic efforts around service provision in adjunct to surgery among females with genital fistula. Data will be presented in summary tables accompanied by narrative description. ETHICS AND DISSEMINATION: Ethics approval is not required for a scoping review. Our results can be used to inform policy, serve as support for funding and development of reintegration programmes and highlight areas for subsequent research. Results will be disseminated at relevant conferences and published in a peer-reviewed journal.

Effect of preoperative bicarbonate infusion on maternal and perinatal outcomes of obstructed labour in Mbale Regional Referral Hospital: a study protocol for a randomised controlled trial.

INTRODUCTION: To improve maternal and fetal outcomes among patients with obstructed labour (OL) in low-resource settings, the associated electrolyte and metabolic derangements must be adequately corrected. Oral fluid intake during labour and preoperative intravenous fluid replacement following OL corrects the associated dehydration and electrolyte changes, but it does not completely reverse the metabolic acidosis, that is, a cause of intrapartum birth asphyxia and a risk factor for primary postpartum haemorrhage due to uterine atony. Sodium bicarbonate is a safe, effective, cheap and readily available acid buffer, that is widely used by sportspeople to improve performance. It also appears to improve fetal and maternal outcomes in abnormally progressing labour. However, its effects on maternal and fetal outcomes among patients with OL is unknown. We aim at establishing the effect of a single-dose preoperative infusion of sodium bicarbonate on maternal and fetal lactate levels and clinical outcomes among patients with OL. METHODS AND ANALYSIS: This will be a double blind, randomised controlled clinical phase IIb trial. We will randomise 478 patients with OL to receive either 50 mL of placebo with standard preoperative infusion of normal saline (1.5 L) or 4.2 g of sodium bicarbonate solution (50 mL of 50 mmol/L) with the preoperative infusion of normal saline (1.5 L). The primary outcome will be mean lactate levels in maternal capillary blood at 1 hour after study drug administration and in the arterial cord blood at birth. We will use the intention-to-treat analysis approach. Secondary outcomes will include safety, maternal and fetal morbidity and mortality up to 14 days postpartum. ETHICS AND DISSEMINATION: Makerere University School of Medicine Research and Ethics Committee and Uganda National Council for Science and Technology have approved the protocol. Each participant will give informed consent at enrollment. TRIAL REGISTRATION NUMBER: PACTR201805003364421.
