A Survey on Current Practices of Umbilical Cord Clamping in Malaysia.

Background: Delayed cord clamping (DCC) has been demonstrated to have significant benefits in reducing the incidence of intraventricular hemorrhage, blood transfusion and neonatal mortality in preterm neonates and improving hemodynamic and long-term neurodevelopment among term infants. There is no clear guideline on umbilical cord clamping (UCC) practices in Malaysia. Objective: The aim of this survey was to assess the knowledge and practice of DCC among obstetric doctors and midwives in Malaysia, and pediatric colleagues who witness the delivery. Method: This is a cross-sectional survey conducted in childbirth facilities in Malaysia from October 2020 to January 2021. A convenient snowball sampling was adopted. A validated questionnaire was disseminated to practicing obstetric and pediatric doctors and midwives electronically via email and WhatsApp using Google Form. The data were analyzed using descriptive and analytical statistics.
Results: A total of 327 respondents completed the questionnaires, comprising 206 obstetric doctors, 72 pediatric doctors and 49 midwives. The majority of respondents were specialists or higher in rank (53.2%). Only 29% reported the existence of guidelines on UCC in their place of work. Midwives (P = 0.003) and staff of lower ranks and level of education (P < 0.001) appeared to be more aware of the existence of a UCC guideline. Most respondents had positive knowledge of DCC for both term and preterm neonates. A large proportion (82%) of respondents agreed that DCC helped increase neonatal iron stores, and was good for both preterm (70.7%) and term (76.2%) neonates not requiring positive pressure ventilation. Doctors, specialists, those who are 40 years old and above, and those who have been in service for at least 10 years were found to have better knowledge regarding DCC (P < 0.05).
Conclusion: The awareness and practice of obstetric, pediatric and midwifery staff of guidelines on UCC were less than satisfactory. Even though most respondents have good knowledge and positive perception regarding benefits of DCC, these were not translated into their routine practice. Hence, a national guideline emphasizing the benefits of DCC should be made available in all childbirth facilities.

Introduction

Delayed cord clamping (DCC) has been demonstrated to reduce the incidence of intraventricular hemorrhage and the need for neonatal blood transfusion in preterm neonates (1). This practice has also reduced neonatal mortality compared to early clamping in preterm infants (1, 2). The World Health Organization (WHO) recommends DCC >1 min after birth (3) as it can significantly improve hemodynamic and long-term neurodevelopment in term infants (4, 5).

Early or immediate cord clamping (ECC or ICC) is generally defined as clamping of the cord within the first 60 s after birth, and late or DCC is performed more than 60 s after birth or upon cessation of cord pulsation (4, 5).

Although the American College of Obstetricians and Gynecologists (ACOG) recommends a DCC in vigorous term and preterm infants for at least 30–60 s after birth (6), a few studies on DCC practices among healthcare professionals in different countries showed that there are variations in the management of umbilical cord clamping (UCC) and cord milking during normal births (7, 8).

Nevertheless, despite a set time of UCC recommended by WHO and ACOG, some healthcare workers used cessation of cord pulsation or waited until the expulsion of placenta as a set time for UCC (9, 10).

The extent to which this procedure is being practiced in Malaysia is unknown. The aim of this study was to assess the knowledge and practice of DCC among obstetric doctors and midwives in Malaysia, as reported by themselves or by pediatric colleagues who witness the delivery.

Materials and Methods

We conducted a cross-sectional survey involving healthcare setups with childbirth facilities, including private hospitals and maternity centers, government hospitals and teaching hospitals in Malaysia over a period of 3 months from October 2020 to January 2021.

The inclusion criteria were obstetric doctors and midwives who conducted deliveries, and pediatric doctors who witnessed deliveries. Doctors and midwives who were not actively conducting or witnessing childbirths, e.g., retired professionals, were excluded from this survey.

This study was approved by the Universiti Kebangsaan Malaysia (UKM) Research Ethics Committee (Approval Code: JEP-2020-580).

A validated questionnaire in English on UCC practice and knowledge toward DCC from a published survey (11) was used with permission from the previous researcher. The questionnaire was sent to members of the Perinatal Society of Malaysia (PSM) and the Malaysian Pediatric Association (MPA), as well as to individual practicing obstetric and pediatric doctors and midwives in Malaysia via email or WhatsApp using Google Form. A convenient snowball sampling method was deployed.

The questionnaire covered three domains: (1) demographic data, (2) existing UCC practice, and (3) knowledge about DCC. Consent was obtained from all respondents who were provided with information regarding the survey within the Google Form.

Sample Size

The sample size was calculated using Statcalc based on a study done by Ibrahim et al. on current UCC practices and knowledge of obstetricians and midwives toward DCC in Saudi Arabia (11). Based on this study, 70% of the respondents have good knowledge toward DCC. By using Statcalc application version 7.2.4.0, with a confidence interval of 95% and margin of error of 5%, we estimated a sample size of 323. Considering 20% dropouts, we aimed to recruit 388 respondents.

Statistical Analyses

The data were analyzed using the Statistical Package for Social Sciences version 22 (IBM SPSS Statistics 22) for Windows. Results were expressed in percentages. Analyses of comparison of the percentages were conducted using the chi-square test or Fisher's exact test (for non-parametric data). In all analyses, p < 0.05 was taken to indicate statistical significance.

Results

Study Flow Chart

The questionnaire was sent to 367 and 788 members of PSM and MPA respectively (Figure 1). It was also disseminated to individual practicing obstetric and pediatric doctors and midwives in Malaysia via email or WhatsApp using Google Form.

Out of a total of 348 respondents who answered the questionnaire, 327 respondents completed it. This number comprised 206 obstetric doctors, 72 pediatric doctors and 49 midwives. Meanwhile, 21 respondents did not complete the questionnaire. The completed survey rate was therefore 94%.

Demographic Background of Respondents

The majority of the respondents were females (72%), specialists, fellows or consultants (53%), aged between 30–39 years old (53%), and practicing at Government Hospitals (57%). Most respondents had tertiary educational background (99%) and about a third of the respondents were senior staff with working experience of more than 15 years (33.3%) (Table 1).

Existing Umbilical Cord Clamping Practice/Guideline

The majority of respondents (71%) reported no existing UCC guideline in their workplace. Among 29% of respondents who reported the presence of UCC guideline in their practice, only 44 and 50% reported always practicing or practicing most of the time, respectively.

Umbilical Cord Clamping for Term Neonates

About a third of the respondents (35%) reported setting UCC time for term neonates. Among those, the majority (62%) reported setting UCC time at 1–3 min. About one third (35%) reported no reason for this routine UCC practice, 29% followed local UCC protocol, 20% clamped the umbilical cord early to prevent polycythemia or hyperbirubinemia, and 15% clamped the cord when the cord pulsations ceased.

Most respondents (77%) applied earlier UCC or immediate cord clamping when the neonates have poor Apgar scores. Other reasons for earlier UCC were increased vaginal blood loss (41%) and presence of nuchal cord (32%). A fifth (20%) of them reported occasions when early UCC took place without any specific reason.

On the other hand, among occasions for later UCC, most of the respondents (40%) reported no specific reason for practicing that. One third (33%) performed later UCC to fulfill the wish of the parents and 16% waited for cessation of umbilical cord pulsation.

Umbilical Cord Clamping for Preterm Neonates

In preterm neonates, only 26% of the respondents reported a set UCC time. Half of these respondents (49%) reported a set UCC time of 1–3 min. About a third (35 and 32% respectively) of the respondents reported that DCC benefits or ECC benefits to pediatricians (especially when resuscitation is needed) were important for their routine UCC in preterm neonates.

UCC Time in Cesarean Section

During elective cesarean section, 22% of respondents practiced UCC at the same time as vaginal delivery and 20% reported cord milking. Most of them (61%) reported UCC time of 30–59 s. On the other hand, during emergency cesarean section, 20% of the respondents practiced UCC as soon as possible, 17 and 15%, respectively, reported cord milking or practiced UCC at the same time as performed in vaginal delivery. Out of those who reported a specific UCC time during this procedure, 40% carried out UCC at 30–59 s (Table 2).

Existing UCC Practices With Demographic Characteristic

There was a significantly higher rate of reporting the existence of a UCC guideline among midwives compared to doctors (47 vs. 26%, P = 0.003), respondents practicing in government hospital compared to private hospitals (35 vs. 14%, P < 0.001) and lower education compared to higher education (60 vs. 25%, P < 0.001). Government hospitals were hospitals under the Ministry of Health (MOH) while teaching hospitals were governed under the Ministry of Higher Education (MOHE). Lower education comprised secondary education and diploma, while higher education included bachelor's degree, master and PhD. One factor that was significantly associated with a higher rate of reporting of a set time of UCC for term neonates was lower education (50%) compared to 33% among staff with high level of education (P = 0.04). Meanwhile, for preterm neonates, significantly higher rates of reporting of a set time of UCC were found among respondents from Klang Valley (34%), compared to 20% among non-Klang Valley residents (P = 0.006). Similar associations were observed among those with lower education (45 vs. 23% in higher, P = 0.003). The Klang Valley comprises mainly urban areas in Kuala Lumpur and Selangor in the central west coast of the Malaysian peninsular (Table 3).

Knowledge on Delayed Cord Clamping

More than two thirds (71% and 76%) of the respondents agreed that DCC was good for both preterm and term neonates not requiring PPV, respectively. The majority of the respondents (82%) agreed that DCC increased iron stores during the neonatal period in both preterm and term babies. Nearly three quarters (73%) respondents agreed that DCC has valuable effects that extend beyond the neonatal period including better long-term neurodevelopment while 67% agreed that DCC helped stabilize the transition of circulation, lessening the need for inotropic medications and reducing blood transfusion, necrotizing enterocolitis and intraventricular hemorrhage in preterm babies (Table 4).

Discussion

Our study revealed the state of practice of UCC and level of knowledge regarding DCC among obstetric and pediatric doctors, and midwives in Malaysia. The majority (71%) of respondents were not aware of any formal guideline on UCC in their place of practice. Similar findings were seen in previous studies by Ibrahim et al. (11) and Jelin et al. (12). Despite published evidence on the benefits associated with DCC (1–3, 6, 13, 14), only 29% of respondents reported that their institution have a UCC guideline. This was contrary to obstetric practice in a developed country, where DCC is considered a standard of care (6, 13).

One statistically significant finding in reporting the existence of a UCC guideline in the workplace was the significant disparity between midwives (47%) and doctors (26%) (P = 0.003). This was contrary to the observation in the study by Ibrahim et al. (11) where doctors were more aware of the availability of a UCC guideline compared to midwives.

Another survey conducted among midwives in Irish hospitals (14) reported 64.7% of the midwives were aware of the guideline on DCC in their place of practice. Our study also found a statistically significant difference in the reporting of the existence of a set time for UCC for term neonates between staff with lower education vs. those with higher education (60 vs. 25%, P = < 0.001 and 50 vs. 33%, P = 0.04, respectively). Lower education included high school and diploma, indicating midwives. These findings were consistent with the findings of studies by Boerre et al. (9) and Mercer et al. (15). Furthermore, some midwifery institutions such as the American College of Nurse-Midwives (ACNM) have adopted DCC as a standard practice for both preterm and term newborns (16).

Midwives have slightly higher rates of having a set time for UCC for both term and preterm neonates than doctors (39 vs. 35% and 31 vs. 25%, respectively), although the differences were not statistically significant (P = 0.600 and 0.392 respectively). Similar findings were seen in a study by Boerre et al. (9). Interestingly, the UCC practice among midwives was said to be based more on belief, experience and clinical training rather than scientific rationale (15). This possibly explains the disparity between knowledge and practice in our survey, with better DCC practice among midwives, despite poorer knowledge. At the level of diploma education, the emphasis is on technicalities and practice, rather than deep knowledge and scientific evidence. This is the level of education of the vast majority of midwives in Malaysia.

DCC for at least 30–60 s for vigorous term and preterm newborns who do not require resuscitation at birth was incorporated into the curriculum of Neonatal Resuscitation Program (NRP) 7th edition (17). In fact, umbilical cord management plan has been included as one of the 4 important pre-birth questions to the obstetric provider in the NRP 8th edition which was launched in 2021 (18). One of the possible explanation for the above observation in the UCC in Malaysia is that NRP is a mandatory course funded by the government for all the pediatric and obstetrics house officers, medical officers and midwives in Malaysian public and teaching hospitals (19). These categories of providers had the opportunities to learn about the latest information of the DCC guidelines in their NRP training compared to their more senior colleagues, e.g., the fellows and the consultants as well as their counterparts in the private sectors.

A systematic review demonstrated that there were no significant differences between ECC and DCC with regard to adverse neonatal outcomes such as low Apgar score and admission to special care nursery (SCN) or neonatal intensive care unit (NICU), and adverse maternal outcomes such as severe postpartum hemorrhage (4). Having said that, majority of the respondents (77% and 41%) applied ECC to neonates with poor Apgar scores and where mothers had increased vaginal loss, respectively, in this study. Such practices were usually performed in order to assist in neonatal resuscitation or to prevent postpartum hemorrhage (20).

Among the respondents who reported a set UCC time, (26% in preterm and 35% in term neonates), most of them reported a set UCC time of 1–3 min (49% in preterm and 62% in term). This practice is consistent with the recommendation by WHO (3), whereby in both preterm and term neonates who do not require PPV, the cord should not be clamped earlier than 1 min after birth. DCC (no earlier than 1 min after birth) is recommended to improve both maternal and infant health and nutritional outcomes.

The majority of respondents (71 and 76%, respectively) agreed that DCC was good for preterm and term neonates not requiring PPV. These findings are consistent with the study done by Ibrahim et al. (11) where the majority of respondents agreed that DCC is beneficial for both term (69%) and preterm (71%) neonates not requiring PPV. In fact, DCC in preterm neonates who require PPV can now be facilitated by providing a mobile resuscitation trolley before UCC (21) and this was proven to be feasible as demonstrated by Lapcharoensap et al. (22) and Joshi et al. (23). Having said that, only 30% of the respondents agreed that DCC was good for neonates who require PPV. Similar findings were reported by Leslie et al. (13). This may be due to its safety concern and acceptability to clinician and parents of DCC in a newborn who requires PPV is still being investigated (21).

Like previous studies (9, 11), majority of the respondents (82%) agreed that DCC increases iron stores during the neonatal period in both preterm and term babies. Most (73%) respondents agreed that DCC has valuable effects that extend beyond the neonatal period, including better long term neurodevelopment. Two thirds (67%) agreed that DCC helped stabilize the transition of circulation, lessening the need for inotropic medications and reducing blood transfusion, necrotizing enterocolitis and intraventricular hemorrhage in preterm babies. These findings are consistent with a previous systematic review and meta-analyses, which supports current guidelines recommending DCC in preterm infants (4, 24).

In our study, doctors, specialists, males, those who are 40 years old and above, and those who have been in service for at least 10 years have better knowledge regarding DCC. This is quite similar to the findings in the study by Ibrahim et al. (11), where males and those with more than 16 years of practice in obstetrics had good knowledge of DCC. The relatively lower level of knowledge regarding delayed cord clamping among midwives and non-specialists is a matter of concern, because in Malaysia the majority of deliveries in public facilities are conducted by midwives and medical officers who are not specialists yet, and calls for more efforts to educate these two groups of healthcare workers on this issue. The older age and seniority are probably confounded by the specialist status of those who scored well on knowledge assessment.

The strength of this study was the high completed survey rate of 94%. Besides, this study utilized a widely-used validated questionnaire to measure the practice of UCC and knowledge regarding DCC. Furthermore, this was the first study that assessed obstetric and pediatric doctors and midwives on UCC practices and knowledge regarding DCC in Malaysia. It is also the first such survey in the South East Asia region. We hope to alert not only our fellow Malaysian healthcare workers in the related fields, but also regional healthcare professionals, especially in our neighboring developing countries. Similarly, we hope to raise awareness in other Low to Moderate Income Countries (LMICs) elsewhere in the world.

One limitation of this study was that the participants were selected by convenient snowball sampling through email and WhatsApp using Google form, hence not all hospitals in Malaysia participated. We were unable to capture the actual numbers of invitation sent to the potential respondents because of the overlap in membership among the three professional societies, namely the Perinatal Society of Malaysia (PSM), the Malaysian Paediatric Association (MPA), and the Obstetrical and Gynaecological Society of Malaysia (OGSM). Although we were able to send the invitation to more than 1,000 members from PSM (n = 367) and MPA (n = 788) however only about one third (n = 348) of them returned the survey form.

Conclusion

Awareness of the existence of guidelines on UCC was still markedly lacking among Malaysian professionals handling childbirth. Even though most respondents had good knowledge of DCC, this did not translate into their routine practice. Hence, a national guideline emphasizing the benefits of DCC should be made available in Malaysia. This may also help create awareness of the existence of international UCC guidelines.
