Prevalence and Factors Associated with Syphilis among Mothers with Missed Opportunities for Antenatal Syphilis Testing in Rural Western Uganda: A Cross-Sectional Study

Background

Early prenatal syphilis testing and treatment are essential preventative measures for maternal syphilis and associated adverse pregnancy outcomes of pregnancy; however, data shows that two-thirds of all cases are missed among women who visit prenatal care center at least once but are not tested for syphilis. This study determined the prevalence and factors associated with syphilis infection among mothers with missed opportunities for antenatal syphilis testing in rural western Uganda delivered at Fort Portal Regional Referral Hospital (FRRH).

Methods

A cross-sectional study was done during the period from April 2022 to June 2022. A total of 124 participants had been recruited consecutively from postnatal ward of FRRH. Pretested questionnaires were used to obtain information on data required for analysis. Venous blood sampling (2 ml taken from the forearm using anticoagulant free vacutainer) was done for all mothers who missed opportunity for prenatal syphilis testing using both RPR and TPHA. Descriptive statistics followed by binary logistic regression analysis was done using SPSS version 22.0.

Results

The prevalence of syphilis infection was 27 (21.8%). After adjusted analysis, having more than one sexual partners in the past one year was associated with higher odds of syphilis infection (aOR = 24.922, 95% CI: 4.462-139.201, p < 0.001), and staying with the partner was found to be associated with lower odds of syphilis infection (aOR = 0.213, 95% CI: 0.040-1.142, p = 0.050).

Conclusions

The study identified high prevalence of syphilis infection among mothers with missed opportunities for antenatal syphilis testing, and this was positively associated with having more than one sexual partners in the past one year and negatively associated with not staying with partner.

Incidence and Factors Associated with Postspinal Headache in Obstetric Mothers Who Underwent Spinal Anesthesia from a Tertiary Hospital in Western Uganda: A Prospective Cohort Study

Background

The proportion of obstetric mothers reporting postspinal headache (PSH) in Uganda is high. The aim of this study is to determine the incidence and factors associated with postspinal headache among obstetric patients who underwent spinal anesthesia during cesarean section at a tertiary hospital in Western Uganda.

Methods

A prospective cohort study was done on 274 consecutively enrolled obstetric patients at Fort Portal Regional Referral Hospital (FRRH) from August to November 2022. Pretested questionnaires were used to obtain the data needed for analysis. The data were entered into Microsoft Excel version 16, coded, and transported into SPSS version 22 for analysis. Descriptive statistics was used to determine the incidence of postspinal headache. Binary logistic regression was computed to obtain factors associated with postspinal headache.

Results

The overall incidence of postspinal headache was 38.3% (95% CI: 32.5-44.4). Factors with higher odds of developing postspinal headache included using cutting needle (aOR 3.206, 95% CI: 1.408-7.299, p=0.006), having a previous history of chronic headache (aOR 3.326, 95% CI: 1.409-7.85, p=0.006), having lost >1500 mls of blood intraoperatively (aOR 6.618, 95% CI: 1.582-27.687, p=0.010), initiation of ambulation >24 h after spinal anesthesia (aOR 2.346, 95% CI: 1.079-5.102, p=0.032), allowing 2-3 drops of cerebrospinal fluid (CSF) to fall (aOR 3.278, 95% CI: 1.263-8.510, p=0.015), undergoing 2 puncture attempts (aOR 7.765, 95% CI: 3.48-17.326, p ≤ 0.001), 3 puncture attempts (aOR 27.61, 95% CI: 7.671-99.377, p ≤ 0.001) and >3 puncture attempts (aOR 20.17, 95% CI: 1.614-155.635, p=0.004), those prescribed weak opioids (aOR 20.745, 95% CI: 2.964-145.212, p=0.002), nonsteroidal anti-inflammatory drug (NSAID) with nonopioids (aOR 6.104, 95% CI: 1.257-29.651, p=0.025), and NSAID with weak opioids (aOR 5.149, 95% CI: 1.047-25.326, p=0.044). Women with a body mass index (BMI) of 25-29.9 kg/m2 (aOR 0.471, 95% CI: 0.224-0.989, p=0.047) and a level of puncture entry at L3-4 (aOR 0.381, 95% CI: 0.167-0.868, p=0.022) had lower odds of developing PSH.

Conclusions

The incidence of postspinal headache is still high as compared to the global range. This was significantly associated with needle design, amount of cerebro-spinal fluid lost, number of puncture attempts, body mass index, previous diagnosis with chronic headache, amount of intraoperative blood loss, time at start of ambulation, level of puncture entry, and class of analgesic prescribed. We recommend the use of a smaller gauge needle, preventing CSF loss, deliberate attempts to ensure successful puncture with fewer attempts, puncture attempts at L3-4, reducing intraoperative blood loss, earlier ambulation, and prescribing adequate analgesia to reduce the incidence of postspinal headache.

Prevalence of high-risk human papillomavirus infection and associated factors among women of reproductive age attending a rural teaching hospital in western Uganda

BACKGROUND

High-risk HPV is considered a major risk factor for the development of cervical cancer, the most common malignancy among women in Uganda. However, there is a paucity of updated epidemiological data on the extent of the burden and factors associated with hr-HPV infection among women of reproductive age. The aim of this study was to determine the prevalence and genotype distribution of hr-HPV and associated factors among women of reproductive age attending a rural teaching hospital in western Uganda.

METHODS

We conducted a cross-sectional study from April to June 2022. A total of 216 women of reproductive age attending the gynecological outpatient clinic were consecutively enrolled. Interviewer-administered questionnaires were used to collect participant characteristics, cervical specimens were collected by clinicians, and molecular HPV testing was performed using the Cepheid Xpert HPV DNA test. Descriptive statistics followed by binary logistic regression were conducted using SPSS version 22.

RESULTS

The prevalence of hr-HPV was 16.67%. Other hr-HPV types other than HPV 16 and 18 were predominant, with a prevalence of 10.6%; HPV 18/45 (2.31%), HPV 16 (0.46%), and 3.24% of the study participants had more than one hr-HPV genotype. On multivariate logistic regression, an HIV-positive status (aOR = 7.06, CI: 2.77-10.65, p = 0.007), having 3 or more sexual partners in life (aOR = 15.67, CI: 3.77-26.14, p = 0.008) and having an ongoing abnormal vaginal discharge (aOR = 5.37, CI: 2.51-11.49, p = 0.002) were found to be independently associated with hr-HPV infection.

CONCLUSIONS AND RECOMMENDATIONS

The magnitude of hr-HPV is still high compared to the global prevalence. HIV-positive women and those in multiple sexual relationships should be prioritized in cervical cancer screening programs. The presence of abnormal vaginal discharge in gynecology clinics should prompt HPV testing.

Health Care Workers' Experiences, Challenges of Obstetric Referral Processes and Self-Reported Solutions in South Western Uganda: Mixed Methods Study

Introduction

In resource limited settings, the highest burden of adverse maternal-fetal outcomes at referral hospitals is registered from emergency obstetric referrals from lower health facilities. Implementation of referral protocols has not been optimally successful possibly attributed to lack of understanding of profile of obstetric referrals and local challenges faced during implementation process.

Objective

This study described the profile of emergency obstetric referrals, challenges faced in implementation of obstetric referral processes and explored self-reported solutions by health workers.

Methods

This was a mixed methods study done at Mbarara Regional Referral Hospital (MRRH) and health centre IVs in South-Western Uganda. We consecutively recruited emergency obstetric referrals from Isingiro district for delivery at MRRH. Using a pre-tested questionnaire, we collected demographics, obstetric and referral characteristics. We described the profile of referrals using frequencies and proportions based on demographics, obstetric and referral characteristics. We conducted focus group discussions and in-depth interviews with health workers using discussion/interview guides. Using thematic analysis, we ascertained the challenges and health worker self-reported solutions.

Results

We recruited 161 referrals: 104(65%) were below 26 years, 16(10%) had no formal education, 11(7%) reported no income, 151(94%) had no professional-escort, 137(85%) used taxis, 151(96%) were referred by midwives. Common diagnoses were previous cesarean scar (24% [n=39]) and prolonged labour (21% [n=33]). There was no communication prior to referral and no feedback from MRRH to lower health facilities. Other challenges included inconsistencies of ambulance and anesthesia services, electric power, medical supplies, support supervision, and harassment by colleagues. Self-reported solutions included the use of phone call technology for communication, audit meetings, support supervision and increasing staffing level.

Conclusion

Most referrals are of poor social-economic status, use taxis, and lack professional-escort. Health workers suffer harassment, lack of communication and shortage of supplies. We need to experiment whether mobile phone technology could solve the communication gap.

Improved maternal-fetal outcomes among emergency obstetric referrals following phone call communication at a teaching hospital in south western Uganda: a quasi-experimental study

BACKGROUND

Emergency obstetric referrals develop adverse maternal-fetal outcomes partly due to delays in offering appropriate care at referral hospitals especially in resource limited settings. Referral hospitals do not get prior communication of incoming referrals leading to inadequate preparedness and delays of care. Phone based innovations may bridge such communication challenges. We investigated effect of a phone call communication prior to referral of mothers in labour as intervention to reduce preparation delays and improve maternal-fetal outcome at a referral hospital in a resource limited setting.

METHODS

This was a quasi-experimental study with non-equivalent control group conducted at Mbarara Regional Referral Hospital (MRRH) in South Western Uganda from September 2020 to March 2021. Adverse maternal-fetal outcomes included: early neonatal death, fresh still birth, obstructed labour, ruptured uterus, maternal sepsis, low Apgar score, admission to neonatal ICU and hysterectomy. Exposure variable for intervention group was a phone call prior maternal referral from a lower health facility. We compared distribution of clinical characteristics and adverse maternal-fetal outcomes between intervention and control groups using Chi square or Fisher's exact test. We performed logistic regression to assess association between independent variables and adverse maternal-fetal outcomes.

RESULTS

We enrolled 177 participants: 75 in intervention group and 102 in control group. Participants had similar demographic characteristics. Three quarters (75.0%) of participants in control group delayed on admission waiting bench of MRRH compared to (40.0%) in intervention group [p =  < 0.001]. There were significantly more adverse maternal-fetal outcomes in control group than intervention group (obstructed labour [p = 0.026], low Apgar score [p = 0.013] and admission to neonatal high dependency unit [p =  < 0.001]). The phone call intervention was protective against adverse maternal-fetal outcome [aOR = 0.22; 95%CI: 0.09-0.44, p = 0.001].

CONCLUSION

The phone call intervention resulted in reduced delay to patient admission at a tertiary referral hospital in a resource limited setting, and is protective against adverse maternal-fetal outcomes. Incorporating the phone call communication intervention in the routine practice of emergency obstetric referrals from lower health facilities to regional referral hospitals may reduce both maternal and fetal morbidities.

Impact of an educational intervention on WHO surgical safety checklist and pre-operative antibiotic use at a referral hospital in southwestern Uganda

INTRODUCTION

The World Health Organization (WHO) recommends adherence to its surgical safety checklist (SSC) to optimize patient safety and reduce cesarean surgical site infection (SSI). Educational interventions combined with audit and feedback mechanisms on the checklist use by clinicians have the potential to improve adherence and clinical outcomes. Despite the increase in cesarean delivery rates, there is a paucity of data on how such interventions can improve adherence in resource-limited settings.

OBJECTIVE

We performed a quality improvement project to measure the impact of an educational intervention with daily audit and feedback procedures on rates of WHO SSC adherence, including pre-operative antibiotic administration and SSI at Mbarara Regional Referral Hospital maternity ward in Uganda.

METHODS

The study involved chart abstraction of WHO SSC and pre-operative antibiotic use during cesarean deliveries and signs of subsequent SSI in three phases. First, we conducted a retrospective review of all charts from May to June 2018 (pre-intervention phase). Second, we instituted an educational intervention on the WHO SSC and pre-operative antibiotics use, followed by a daily audit of charts and feedback to clinicians from July to August 2018 (the intervention phase). Third, we reviewed charts from September to October 2018 (the post-intervention phase). The WHO SSC adherence, pre-operative antibiotic administration and SSI rates were measured as the proportion of the total cesarean deliveries per study phase and then compared across the three phases.

RESULTS

We reviewed 678 patients' charts (200 in the pre-intervention phase, 230 in the intervention phase and 248 in the post-intervention phase). The mean patient age was 25 years. The use of the WHO SSC was 7% in the pre-intervention phase compared to 92% in the intervention phase (P < 0.001), and 77% in the post-intervention phase (P < 0.001). Pre-intervention antibiotic receipt was 18% compared to 90% in the intervention phase (P < 0.001) and 84% in the post-intervention phase (P < 0.001). The documented SSI rate in the pre-intervention phase was 15% compared to 7% in the intervention phase (P = 0.02) and 11% in the post-intervention phase (P = 0.20).

CONCLUSIONS

An educational intervention, daily audit and feedback to clinicians increased the use of the WHO SSC and prophylactic antibiotics for cesarean delivery-although the rates waned with time. Research to understand factors influencing the checklist use and antibiotic prophylaxis including prescriber knowledge, motivation and clinical process is required. Implementation interventions to sustain usage and impact on clinical outcomes need to be explored.

Incidence of postpartum infection, outcomes and associated risk factors at Mbarara regional referral hospital in Uganda

Background

There is a paucity of recent prospective data on the incidence of postpartum infections and associated risk factors in sub-Saharan Africa. Retrospective studies estimate that puerperal sepsis causes approximately 10% of maternal deaths in Africa.

Methods

We enrolled 4231 women presenting to a Ugandan regional referral hospital for delivery or postpartum care into a prospective cohort and measured vital signs postpartum. Women developing fever (> 38.0 °C) or hypothermia (< 36.0 °C) underwent symptom questionnaire, structured physical exam, malaria testing, blood, and urine cultures. Demographic, treatment, and post-discharge outcomes data were collected from febrile/hypothermic women and a random sample of 1708 normothermic women. The primary outcome was in-hospital postpartum infection. Multivariable logistic regression was used to determine factors independently associated with postpartum fever/hypothermia and with confirmed infection.

Results

Overall, 4176/4231 (99%) had ≥1 temperature measured and 205/4231 (5%) were febrile or hypothermic. An additional 1708 normothermic women were randomly selected for additional data collection, for a total sample size of 1913 participants, 1730 (90%) of whom had complete data. The mean age was 25 years, 214 (12%) were HIV-infected, 874 (51%) delivered by cesarean and 662 (38%) were primigravidae. Among febrile/hypothermic participants, 174/205 (85%) underwent full clinical and microbiological evaluation for infection, and an additional 24 (12%) had a partial evaluation. Overall, 84/4231 (2%) of participants met criteria for one or more in-hospital postpartum infections. Endometritis was the most common, identified in 76/193 (39%) of women evaluated clinically. Twenty-five of 175 (14%) participants with urinalysis and urine culture results met criteria for urinary tract infection. Bloodstream infection was diagnosed in 5/185 (3%) participants with blood culture results. Another 5/186 (3%) tested positive for malaria. Cesarean delivery was independently associated with incident, in-hospital postpartum infection (aOR 3.9, 95% CI 1.5–10.3, P = 0.006), while antenatal clinic attendance was associated with reduced odds (aOR 0.4, 95% CI 0.2–0.9, P = 0.02). There was no difference in in-hospital maternal deaths between the febrile/hypothermic (1, 0.5%) and normothermic groups (0, P = 0.11).

Conclusions

Among rural Ugandan women, postpartum infection incidence was low overall, and cesarean delivery was independently associated with postpartum infection while antenatal clinic attendance was protective.

Antimicrobial-resistant infections among postpartum women at a Ugandan referral hospital

INTRODUCTION

Puerperal sepsis causes 10% of maternal deaths in Africa, but prospective studies on incidence, microbiology and antimicrobial resistance are lacking.

METHODS

We performed a prospective cohort study of 4,231 Ugandan women presenting to a regional referral hospital for delivery or postpartum care, measured vital signs after delivery, performed structured physical exam, symptom questionnaire, and microbiologic evaluation of febrile and hypothermic women. Malaria rapid diagnostic testing, blood and urine cultures were performed aseptically and processed at Epicentre Mbarara Research Centre. Antimicrobial susceptibility and breakpoints were determined using disk diffusion per EUCAST standards. Hospital diagnoses, treatments and outcomes were abstracted from patient charts.

RESULTS

Mean age was 25 years, 12% were HIV-infected, and 50% had cesarean deliveries. Approximately 5% (205/4176) with ≥1 temperature measurement recorded developed postpartum fever or hypothermia; blood and urine samples were collected from 174 (85%), and 17 others were evaluated clinically. Eighty-four (48%) had at least one confirmed source of infection: 39% (76/193) clinical postpartum endometritis, 14% (25/174) urinary tract infection (UTI), 3% (5/174) bloodstream infection. Another 3% (5/174) had malaria. Overall, 30/174 (17%) had positive blood or urine cultures, and Acinetobacter species were the most common bacteria isolated. Of 25 Gram-negatives isolated, 20 (80%) were multidrug-resistant and cefepime non-susceptible.

CONCLUSIONS

For women in rural Uganda with postpartum fever, we found a high rate of antibiotic resistance among cultured urinary and bloodstream infections, including cephalosporin-resistant Acinetobacter species. Increasing availability of microbiology testing to inform appropriate antibiotic use, development of antimicrobial stewardship programs, and strengthening infection control practices should be high priorities.

Multisyringe flow injection analysis of stable and radioactive strontium in samples of environmental interest

A multisyringe flow injection (MSFIA) method for the determination of stable and radioactive strontium, using a solid phase resin (Sr-Resin), has been developed. Strontium concentrations are determined by atomic emission spectroscopy and by a low background proportional counter. The method has been applied to different samples (water, milk and soil) of environmental interest. The LLD of the stable and radioactive Sr were 10 microg/l and 0.01 Bq, respectively. The standard deviation of the separation procedure is 2% (n=10).
