Reducing Gastroschisis Mortality: A Quality Improvement Initiative at a Ugandan Pediatric Surgery Unit

Abstract

Introduction

With modern treatment, survival of gastroschisis exceeds 90% in high-income countries. Survival in these countries has been largely attributed to prenatal diagnosis, delivery at tertiary facilities with timely resuscitation, timely intervention, parenteral nutrition and intensive care facilities. In sub-Saharan Africa, due to lack of these facilities, mortality rates are still alarmingly high ranging from 75 to 100%. In Uganda the mortality is 98%.

Aim

The aim of this study was to reduce gastroschisis mortality in a feasible, sustainable way using a locally derived gastroschisis care protocol at a referring hospital in Western Uganda.

Methods

Data collection was performed from January to October 2018. Nursing staff were interviewed regarding the survival and management of gastroschisis babies. A locally derived protocol was created with staff input and commitment from all the team members.

Results

Four mothers absconded and 17 babies were cared for using the newly designed protocol. Seven survived and were well at one month post discharge follow-up, reducing the mortality for this condition from 98 to 59%.

Conclusion

A dedicated team with minimal resources can significantly reduce the mortality in gastroschisis by almost 40% using a locally derived protocol.

Introduction

Gastroschisis is a congenital anomaly characterized by a defect in the anterior abdominal wall through which abdominal contents protrude. Gastroschisis is increasing throughout the world for unknown reasons. This condition now occurs in about 1 of every 2000–4000 live births [1].

Babies born with gastroschisis ideally should have a good prognosis and long-term survival of >90% [2, 3]. With modern treatment, survival exceeds 90% in developed countries [3, 4]. Survival in these countries has been largely attributed to prenatal diagnosis, delivery at a tertiary facility with timely resuscitation, timely intervention, availability of total parenteral nutrition and neonatal intensive care units and neonatal ICU. Unfortunately, these facilities and medication are always lacking in resource-limited countries. In sub-Saharan Africa, mortality rates for gastroschisis still remain alarmingly high ranging from 90 to 100% [5]. In Uganda mortality for gastroschisis is 98% [6].

It could be argued that local and national government including global health funding could be better spent elsewhere, rather than on a relatively uncommon congenital anomaly like gastroschisis. However, gastroschisis is potentially curable with disability-free long-term survival achievable in the well-resourced setting [7]. Looking at disability-adjusted life years (DALYs) (DALYs = years of life lost + years lived with disability), the potentially avertable DALYs would be high, making the case for enhanced pediatric surgery capacity [8]. The same would hold for a number of other congenital anomalies, but gastroschisis is unique in terms of the rising worldwide incidence and the potential curability [9].

In the low-resource setting, there is a huge unmet burden of infectious diseases and thus a rare disease like gastroschisis is not prioritized in terms of securing parental nutrition and neonatal intensive care beds (NICU). Due to the lack of resources, we attempted to use available resources in the management of gastroschisis. The aim of this study was to reduce gastroschisis mortality in a feasible, sustainable way using a locally designed gastroschisis protocol at Mbarara hospital, a regional referral hospital in Western Uganda.

We describe an intervention to improve gastroschisis outcomes by applying a local protocol (see Table 1) using the available ward supplies and staff. The protocol was developed on the basis of the gaps identified in the study by Wesonga et al. [6], on “opportunities for improved survival for gastroschisis in Uganda” and capitalizes on aggressive resuscitation, primary bedside staged closure by a pediatric surgeon or fellow in attendance, early enteral feeds and effective team work.

Table 1 Protocol

Aim

To determine whether mortality of gastroschisis can be reduced by using a locally designed protocol with locally available material for the management of gastroschisis .

Methods

The medical records for gastroschisis for the past 1 year were reviewed and ward staff were interviewed regarding survival of gastroschisis for the past year.

Ward meetings were held to discuss gastroschisis mortality and how best outcomes could be improved. Knowledge, attitude and previous practices were also discussed. The published article on opportunities for improved survival in Uganda was reviewed and gaps identified [6]. The protocol was based on these gaps.

A quality improvement study team (QIST) was created from the routine ward staff that continued to perform their normal duties over and above being part of the QIST. Every team member on duty familiarized themselves with the protocol to avoid variations. Furthermore, a team member was on standby at all times in case the on call team member required assistance. The pediatric surgery fellow was the lead core team member.

Intervention

The entire ward staff and team members plus the team leader were informed as soon as a baby with gastroschisis was admitted. The role of the admitting staff member was to cover the exposed bowel with a urine bag and assist with the resuscitation of the baby. Parental involvement was actively encouraged. The protocol was instituted (Table 1).

Data were collected for demography, mortality and morbidity. Data on gastroschisis were also reviewed for a year before instituting the protocol. Staffs were interviewed regarding outcomes of gastroschisis 1 year before the start of the protocol.

Ethical consideration

Informed consent was obtained before the interventions, and continuous engagement of the parents was requested. Ethical permission was obtained from the Mbarara ethical committee.

Results

Over a 10-month period from January 2018–October 2018, a total of 21 babies were admitted to the unit with gastroschisis. Male-to-female ratio was 2.4:1. The mode of delivery was spontaneous vaginal delivery in 90% of cases. The average birth weight was 1.97(1–2.6) kg. The average time to full feeds was 14 (7–21) days. The average length of hospital stay was 17 (11–24) days. The entire bowel was reduced by the 8th day of admission. All except two were reduced in improvised silo. One wound was covered with umbilical cord. One baby had segmental bowel necrosis, and primary closure was possible after resection and primary anastomosis. One baby had associated intestinal atresia and died on day 10. Fourteen mothers were between 15 and 20 years old (67%), 4 were between 21 and 29 years old (19%) and 3 were between 30 and 35 years of age (14%).

Four mothers absconded with the babies before discharge. Seventeen babies stayed on ward until discharge or death. Seven babies (Table 2) were discharged from hospital, and at 1-month review they were all alive and gaining weight adequately. Ten babies died mainly at night when there is shortage of workforce (Table 3). Mortality was reduced from 98% of the previous year to 58% during year of instituting the protocol.

Discussion

The Mbarara pediatric surgical unit has a bed capacity of 17. It has two elective operating days in a week, one surgical outpatient day in a week and 24–7 emergency services. The unit sees an average of 120 outpatients in a month and does an average of 50 operations per month. The pediatric surgery workforce includes 1 pediatric surgeon, a pediatric surgery fellow and 6 nurses.

Gastroschisis has remained a challenge in Mbarara hospital with mortality of almost 100% over the past decade. Thus, it had become the norm for gastroschisis to be a non-survivable condition in this hospital. Some clinicians were still hopeful and continued to resuscitate these babies and place an improvised silo while others informed the parents of the poor of prognosis of these babies and provided palliative care.

This quality improvement gastroschisis protocol translated into improved survival as evidenced by reduction in mortality from 98% pre-protocol era to 58% post-protocol era.

A Ugandan study on gastroschisis by Wesonga et al. [6] shows that the mortality rate for children with gastroschisis is 98% which is alarmingly high in the context of almost universal survival in high-income countries. We identified a number of disparities in our institution: the lack of access to prenatal ultrasound and the low accuracy of diagnosis. Without accurate prenatal diagnosis, mothers could not be counseled to deliver their babies in a hospital where pediatric surgery is available. Unfortunately, even with in-hospital delivery the mortality was high. Lack of basic neonatal care, failure of early surgical management, unavailability of total parenteral nutrition and lack of central venous access are most of the contributing factors. The study concluded that many of these deaths are preventable, and improvements in both patient care and education for healthcare providers would give hope for the survival of babies with gastroschisis in Uganda.

The present quality improvement study was founded on the outcomes of this study. Much effort was put on factors that could be easily modified like resuscitation, early surgical management and early oral feeds to combat need for TPN. All improvised silos were sewn at the bedside, and thus, there was no need for operating space which was a large contributor to mortality in the previous study [6]. In the present study, we noted that most deaths occurred at night when the staffing levels were very low which is a factor to consider for the future.

In-house vs outside delivery was not an issue, since all the survivors’ except one in this quality improvement study were born outside the hospital. We were able to provide adequate and early resuscitation to most of our patients noting that early resuscitation is a major predictor of mortality as described by Stevens et al. [10]. In their study, poor resuscitation was a more significant predictor of mortality rather than postnatal transfer time. The high mortality rate (65%) was not due to lengthy transfer times but the poor clinical condition of the patients on arrival at the hospital, which relates to deficiencies in the neonatal transfer system and had a direct impact on the survival of neonates with gastroschisis.

Gastroschisis-related infant mortality in Zimbabwe is associated with well-known risk factors, such as low birth weight, prematurity and teenage mothers. However, modifiable factors identified in this study signify potential opportunities for developing innovative approaches to perinatal care in such a resource-constrained environment [11]. We have shown this successfully in our present QI study.

Multidisciplinary team training, nurse empowerment and the intentional involvement of mothers in monitoring and care provision may contribute to improving survival. The nurse-to-patient ratio Mbarara Hospital is about 1:10, and at any one point we can have 3 gastroschisis babies on ward at the same time. One of the major challenges during this QI study was inadequate nursing care. Thus, to combat this we actively involved the mothers to learn basic nursing care like nasogastric aspirations, dressings change and stopping/starting IV fluids.

The outcome of this study has had a great impact on the system and the morale of the clinical team and the community. Attitudes and practice in the management of gastroschisis has changed for the better; however, a huge challenge still remains of instituting information on the protocol across other regional referrals hospital in Uganda. The relevant health authorities are aware that gastroschisis is a survivable disease and therefore should no longer be neglected.

Limitations

There is lack of data on mothers who absconded from hospital before discharge.

Conclusion

A locally derived gastroschisis protocol showed a reduction in mortality by almost 40%. Babies born with gastroschisis can survive without TPN or ICU facilities and with minimal available resources in poor-income countries. They need a dedicated team with a positive attitude. However, additional work is needed especially in early referrals, adequate nursing staff especially on night shift and availability of stable supply of oxygen and fluid pumps. We suggest a larger multicenter study with the aim of creating a database and developing a national gastroschisis protocol.
