Summary

Objective:

To describe practices and interventions used during labor and childbirth and factors associated with such practices in puerperae in the state of Sergipe.

Method:

A cross-sectional study with 768 postpartum women from 11 maternity hospitals interviewed 6 hours after delivery, and hospital records review. The associations between best practices and interventions used during labor and delivery with exposure variables were described using simple frequencies, percentages, crude and adjusted odds ratio (ORa) with the confidence interval.

Results:

Of the women in the study, 10.6% received food and 27.8% moved during labor; non-pharmacological methods for pain relief were performed in 26.1%; a partogram was filled in 39.4% of the charts; and an accompanying person was present in 40.6% of deliveries. Oxytocin, amniotomy and labor analgesia were used in 59.1%, 49.3% and 4.2% of women, respectively. Lithotomy position during childbirth was used in 95.2% of the cases, episiotomy in 43.9% and Kristeller maneuver in 31.7%. The variables most associated with cesarean section were private financing (ORa=4.27, 95CI 2.44-7.47), higher levels of education (ORa=4.54, 95CI 2.56-8.3) and high obstetric risk (ORa=1.9, 95CI 1.31-2.74). Women whose delivery was funded privately were more likely to have an accompanying person present (ORa=2.12, 95CI 1.18-3.79) and to undergo labor analgesia (ORa=4.96, 95CI 1.7-14.5).

Conclusion:

Best practices are poorly performed and unnecessary interventions are frequent. The factors most associated with c-section were private funding, greater length of education and high obstetric risk.

As associações entre as boas práticas e intervenções utilizadas durante o trabalho de parto e o parto com as variáveis de exposição foram descritas em frequências simples, percentuais, razões de chances brutas e ajustadas (ORa) com o intervalo de confiança.

Resultados:

Das mulheres estudadas, 10,6% receberam alimentos e 27,8% movimentaram-se durante o trabalho de parto; medidas não farmacológicas para alívio da dor foram realizadas em 26,1%; o partograma estava preenchido em 39,4% dos prontuários; o acompanhante esteve presente em 40,6% dos partos. O uso de ocitocina, amniotomia e analgesia ocorreram em 59,1%, 49,3% e 4,2% das mulheres, respectivamente. O parto ocorreu na posição de litotomia em 95,2% dos casos, houve episiotomia em 43,9% e manobra de Kristeller em 31,7%. Os fatores mais associados à cesariana foram ser usuárias do setor privado de saúde (ORa=4,27; 95CI 2,44-7,47), ter maior escolaridade (ORa=4,54; 95CI 2,56-8,3) e alto risco obstétrico (ORa=1,9; 95CI 1,31-2,74). Usuárias do setor privado tiveram maior presença do acompanhante (ORa=2,12; 95CI 1,18-3,79) e analgesia (ORa=4,96; 95CI 1,7-14,5).

Conclusão:

Boas práticas obstétricas são pouco utilizadas e intervenções desnecessárias são frequentes, e os fatores mais associados à cesariana foram ser usuária do setor privado de saúde, ter maior escolaridade e alto risco obstétrico.

INTRODUCTION

The model for parturition care in Brazil until the mid-twentieth century was one that relied mostly on home care, which was provided mainly by female accoucheuses and midwives. Since then, there has been a process of hospitalization and medicalization of delivery with a large increase in the rates of interventions such as episiotomy, use of oxytocin and cesarean section.1,2 The trend towards an increase in the number of cesarean sections is observed worldwide – except for the Netherlands and other European countries, where it is minor – with Brazil as a leader.3

Two decades ago, the World Health Organization (WHO) published the report "Safe Motherhood" with recommendations on appropriate obstetric practices and those to be avoided.4 Evidence based on systematic reviews suggests that ambulating and staying in upright positions during the first period of labor reduces the duration of labor, the risk of cesarean section and the use of analgesia, while not posing risks to the mother or the newborn.5 There is no justification for restricting liquids or foods during labor for women at low risk of complications.6 Likewise, there is no evidence to support routine amniotomy, since this does not reduce the duration of labor or the cesarean section rate.7 The presence of a support person (doula) during labor is associated with reduction in the use of analgesia, lower rate of operative delivery and greater maternal satisfaction.8 If their presence is not possible, women should be encouraged to choose an accompanying person (relative or friend).9 Performing selective episiotomy is associated with less posterior perineal trauma, less need for suturing and fewer complications, with no difference in pain intensity and severe vaginal or perineal trauma when compared to routine episiotomy.10 The Kristeller maneuver, albeit safe for the fetus, increases the risk of vaginal and cervical laceration and should thus be avoided.11

In order to improve prenatal care and delivery and adapt obstetric practices to current recommendations, the Brazilian Ministry of Health has been adopting several public policies: the National Prenatal and Birth Program (PHPN) by means of the Ordinance GM No. 569, of June 1, 2000;12 the guarantee of right to an accompanying person during labor, childbirth and immediate puerperium (Law 11,108, of April 7, 2005)13 and the so-called Stork Network (Rede Cegonha, Ordinance No. 1459, of June 24, 2011), which reinforces and expands on the PHPN proposal,14 as well as the definition of the National Directive for Normal Labor Care issued by the National Technology Incorporation Commission (CONITEC) of the Unified Health System (SUS, in the Portuguese acronym) (CONITEC- SUS, 2016).2

Data from the "Birth in Brazil" (Nascer no Brasil) study showed that the prevalence of good practices in conducting labor was lower in the North and Northeast regions.15 The state of Sergipe is the smallest in Brazil, located in the Northeast region. In 2014, 34,369 live births and a maternal mortality rate of 61/100,000 live births (DATASUS, the SUS Department of Informatics)16 were recorded, well above that which is considered acceptable by the WHO, namely up to 20/100,000. There is no study with a representative sample at the state level evaluating the use of "good practices" and interventions in childbirth. The purpose of this study was to describe adequate practices used during labor/delivery (feeding, movement, use of non-pharmacological methods for pain relief, monitoring of labor using partogram and the presence of an accompanying person during labor) and interventions aimed at women (use of oxytocin, amniotomy, analgesia, episiotomy, Kristeller maneuver, lithotomy delivery, and cesarean section). It also aimed at investigating factors associated with such practices in puerperae at 11 maternity hospitals in the state of Sergipe.

METHOD

This is a cross-sectional study extracted from the "Birth in Sergipe" (Nascer em Sergipe), a cohort study conducted between June 2015 and April 2016. The local team was trained by investigators from Fundação Osvaldo Cruz (Fiocruz), who participated in the national study, to evaluate a sample representative of the state of Sergipe. The method used in the "Birth in Brazil"17 study was reproduced. Public, private and mixed maternities that had more than 500 births per year were included.

Sample size was calculated considering a cesarean section rate of 38% (DATASUS, 2011),16 totaling 358 women to be interviewed. This figure was calculated as an estimate of cesarean section prevalence considering all institutions with 500 or more births in the state of Sergipe, with a 95% confidence interval. To increase the power of the study and evaluate associations with other variables, we doubled the sample to 768 puerperae and their conceptuses. An allocation proportional to the size of the institution was adopted for distributing the calculated sample size.

The interviewers stayed at least 7 days at each institution. If the number of puerperae was reached before the end of that period, a random number limiting the maximum daily number of interviewees would be drawn up so as to ensure that all 7 scheduled days were reached. We included all randomly selected women who had been admitted to chosen maternities at the time of delivery and their conceptuses, alive or dead, with birth weight greater than or equal to 500 g and/or gestational age greater than or equal to 22 weeks, provided they accepted to participate in the study and sign a Voluntary and Informed Consent Form (VICF). We excluded the women who could not speak and/or understand Portuguese or who could not be reached by telephone between 45-60 days and 6 to 8 months postpartum. No puerpera that was considered eligible refused to participate. There were two eligible patients who were lost due to complications in the immediate puerperium and progressed to death.

Face-to-face interviews with the puerperae were carried out between 6 and 24 hours after delivery. Data was extracted from woman's and newborn's records after discharge (or death). In the case of prolonged hospital stay, data was extracted 42 days after admission to hospital and 28 days after the newborn's birth. Their prenatal cards were photographed, and the information were entered into the database. Follow-up phone interviews were conducted at 45-60 days and 6 to 8 months after delivery to investigate maternal and neonatal complications in the short and medium terms.

The (independent) exposure variables studied were the source of financing: public (SUS system) or private (private or granted by health insurance companies); locality: capital or countryside; age (10 to 19; 20 to 34; > 35); number of years of formal education (7 or less; 8-10; 11 or more); self-reported skin color (white or non-white); number of previous deliveries (0; 1-2; 3 or more); and usual or high obstetric risk (gestational diabetes, gestational or pre-gestational high blood pressure, obesity, AIDS, gestational age lesser than 37 weeks or greater than 41 weeks at the time of birth, multiple pregnancy, non-cephalic presentations, birth weight less than 2,500 g or greater than 4,499 g and below the fifth-percentile or above the ninety-fifth percentile of weight for gestational age). It was used the same risk classification as the one adopted in the "Birth in Brazil" study.18

The outcomes evaluated (dependent variables) were "good practices" and obstetric interventions during labor/delivery. The good practices during labor/delivery investigated were: feeding, movement during labor, use of non-pharmacological procedures for pain relief, use of partogram and presence of an accompanying person, whereas interventions during labor/delivery were: use of oxytocin, amniotomy, epidural analgesia, elective or intrapartum cesarean section (i.e. in patients who went into labor), episiotomy, use of the Kristeller maneuver, and delivery in the lithotomy position.

For statistical analysis, the associations between good practices and interventions used during labor and delivery with exposure variables were described by simple frequencies, percentages, crude odds ratios, as well as their confidence interval. In the multivariate analysis, odds ratios were adjusted by using a generalized linear model with Bernoulli distribution (logistic regression) with robust standard errors. Occasionally, odds ratios could not be calculated due to the presence of null crossings between variables (separation problems).19

The project was approved by the Ethics Committee for Research involving human beings at the Universidade Federal de Sergipe, CAAE: 22488213.4.0000.5546. The participants' identity and rights have been preserved. This research project follows the recommendations of Normative 196/96 pursuant to Resolution No. 466/2012, which has replaced Resolution No. 196, of October 10, 1996, of the National Health Council of the Ministry of Health (Conselho Nacional de Saúde do Ministério de Saúde), Brasília, DF, Brazil. The puerperae signed a VICF, having a guaranteed right to terminate participation at any moment, without suffering any damage.

RESULTS

The participants' mean age was 25 years: 21.4% were adolescents and 7.3% were aged 35 years or more. Brown skin was the most frequently self-reported skin color (75.1%), with yellow and indigenous skin colors corresponding to 3% and 0.4%, respectively. With regard to education, 48.7% had 7 or less years of formal education and 33.2% had 8-10 years. Most participants performed no paid work (55.5%) and lived with their partner (84.3%). Regarding parity, 43.2% were primiparous and 17.1% had three or more previous pregnancies. Delivery was normal in 59.4% and cesarean section was performed in 40.46% of cases. According to the type of financing involved, the cesarean section rate was 35% at public health care services and 75% at private ones.

Feeding and movement during labor, use of non-pharmacological measures for pain relief, use of partogram for labor monitoring, use of oxytocin, epidural analgesia and intrapartum cesarean section were evaluated in the 566 (73.6%) patients who went into labor. As far as interventions at delivery, episiotomy, Kristeller maneuver and delivery in the lithotomy position were evaluated in the 456 (59.4%) patients who had normal delivery. The presence of an accompanying person during delivery and elective cesarean section were evaluated among all patients in the study. Amniotomy was evaluated in 389 patients who went into labor, and those who had premature rupture of membranes before admission were excluded.

In 10.6% of cases, women were given food and 27.8% moved during labor; non-pharmacological measures for pain relief were taken in 26.1%; the partogram was filled out in 39.4% of medical records; and the accompanying person was present in 40.6% of deliveries. With respect to interventions, oxytocin was used in 59.1% and amniotomy in 49.3% of cases. Labor analgesia was provided to 4.2% of women. Delivery occurred in the traditional lithotomy position in 95.2% of cases; episiotomy was performed in 43.9% and Kristeller maneuver, in 31.7%. Among the patients who went into labor, 14.3% required resolution by cesarean section, whereas 26.3% of women participating in the study had elective cesarean section. Most deliveries (75%) were performed by a medical obstetrician and 17% by a nurse obstetrician.

The associations between independent (sociodemographic) variables and the outcomes assessed: "good practices" and interventions during labor and delivery can be observed, respectively, in Tables 1, 2 and 3. After adjusting for confounding variables, we found that having a privately funded birth was associated to greater likelihood of having an accompanying person during labor (ORa=2.12; 95CI 1.18-3.79) (Table 1), use of analgesia (ORa=4.96; 95CI 1.7-14.5) (Table 2), indication of intrapartum cesarean section (ORa=5.89; 95CI 3.11-11.1); or elective cesarean section (ORa=4.27; 95CI 2.44-7.47) (Table 3) and less chance of using oxytocin (ORa=0.23; 95CI 0.1-0.52) (Table 2). Patients in the countryside are more likely to eat (ORa=2.85; 95CI 1.5-5) and to have their labor monitored by a partogram (ORa=4.34; 95CI 3-6.6) (Table 1), but were also the ones who underwent Kristeller maneuver more often (ORa=1.7; 95CI 1.1-2.6) (Table 3), whereas those in the capital were the most likely to have the presence of an accompanying person during labor (ORa=5.76; 95CI 3.86-8.58) (Table 1), be given oxytocin (ORa=4.17; 95CI 2.8-6.21) and labor analgesia (ORa=7.38; 95CI 1.65-33.1) (Table 2). Regarding age, women between 10 and 34 years of age underwent a greater number of non-pharmacological procedures for pain relief (ORa=3.12; 95CI 1.14-8.51) (Table 1) whereas in those aged between 10 and 19 years a larger number of lithotomy deliveries (ORa=16.28; 95CI 1.75-151) was performed compared with those aged 35 years or older (Table 3). As for schooling, those who had 11 or more years of formal education reported the presence of an accompanying person during delivery more frequently than those who had up to seven years of education (ORa=3.12; 95CI 1.6-5.88) (Table 1), as well as more elective c-sections (ORa=4.54; 95CI 2.56-16.6) (Table 3). Women with one or two previous deliveries reported more frequently having an accompanying person during labor than those with three or more previous deliveries (ORa=1.88; 95CI 1.2-2.7) (Table 1). They also underwent Kristeller maneuvers less often than those with three or more previous deliveries (ORa=0.52; 95CI 0.34-0.81), whereas these, in turn, were at a higher risk of episiotomy than those with one to two previous deliveries (ORa=1.7; 95CI 1.16-2.77) (Table 3). Finally, pregnant women classified as being at a high risk stood a higher chance of eating during labor (ORa=2.38; 95CI 1.36-4.16); recorded more deliveries monitored by a partogram (ORa=2.22; 95CI 1.46-3.39) (Table 1) and had a higher number of intrapartum (ORa=2.24; 95CI 1.44-3.47) and elective (ORa=1.9; 95CI: 1.31-2.74) c-sections than did pregnant women at low-risk (Table 3).

DISCUSSION

Periodic reviews of practices used in obstetric care should be conducted to verify whether the recommendations of reviews and international9 and national2 guidelines are being followed.

The so-called "good practices" recommended for conducting labor were used in less than 30% of women in the state of Sergipe, whereas interventions that should not be used due to lacking evidence that supported the need thereof and/or due to proven damage such as the use of oxytocin, amniotomy, episiotomy, Kristeller maneuver (which is strongly discouraged) and lithotomy delivery2 were very frequently performed. This result is similar to that found by the "Birth in Brazil" study, which detected that good practices are used in less than 50% of deliveries and interventions such as Kristeller maneuver (37%) and episiotomy (56%) are still widely practiced.15

In the state of Sergipe, as much as in Brazil, there is great diversity in the care of patients in the public health care system when compared to the private system. Women receiving care in the private health care system had more comfortable deliveries, with a more frequent use of analgesia and a less frequent use of oxytocin. In addition, they had the presence of accompanying persons more frequently, unlike those receiving care in the public health care system, who received oxytocin more often as well as less analgesia, characterizing the practice of medicalized and painful deliveries. However, the indications of cesarean section, either electively or during labor, were more frequent in women receiving care at the private health care system, from the capital city of Sergipe, with greater lengths of formal education and at a high obstetric risk. A Spanish study has shown that patients from the private health care system and private hospitals with fewer births are more likely to undergo cesarean section and invasive procedures such as episiotomy or instrumental vaginal delivery.20 Another study evaluated the role played by the source of payment in increasing cesarean section rates in Brazil between 1998 and 2008 and showed that private payment was associated with higher cesarean rates, as well as an older age, greater length of formal education and residing outside the Northeast region.21

A national survey carried out in Brazil in 2010 also showed a higher frequency of cesarean delivery among older women and those with greater lengths of formal education, primiparous, whose prenatal care was provided by the private health care system and residing in the South, Southeast and Midwest22 regions. A study published in 2014 shows a change in this geographical pattern, with the frequency of cesarean sections being higher in the North and lower in the Southeast regions, despite the fact that the latter has the highest coverage by health insurance companies in Brazil. This may indicate the beginning of a change due to the movements in favor of humanized delivery and greater access to evidence-based information on good obstetric practices.15

We can attribute the reasons for a higher frequency of cesarean sections among women receiving care in the private system and with greater lengths of formal education to maternal choice, since many times the procedure is performed without a medical indication.23 However, a study conducted in Brazil with 1,136 women showed that 70 to 80% of pregnant women in both health systems (public and private) reported their preference at the beginning of prenatal care for vaginal delivery, which implies that high rates of cesarean sections do not seem to reflect a maternal option.24

Labor analgesia is a resource that can minimize the fear of pain that some women have and reduce the indication for cesarean section at the request of the pregnant woman. The National Directive for Normal Labor Care recommends that the patient receive guidance during her prenatal care about the potential risks related to analgesia, namely a longer duration of the second period of delivery and a greater chance of instrumental vaginal delivery. The maternal request would be sufficient and an indication for it to be performed, irrespective of the stage of labor and the degree of dilation.2 A randomized study with patients receiving regional analgesia versus non-pharmacological measures for pain relief showed a greater reduction in pain scores and satisfaction with the analgesic technique and delivery in the group that was given regional analgesia.25 The percentage of patients receiving analgesia in our study was higher in parturients in the private health care system, despite it being a universal right. The large numbers of births, small number of anesthetists and procedure rooms in public institutions can justify such inequality.

The current legislation in Brazil determines that health care services allow the presence of an accompanying person, someone to be indicated by the parturient, during labor, delivery and immediate postpartum.13 The presence of an accompanying person is correlated to the minimization of feelings of loneliness and pain, which allows for a positive parturition experience.26 However, despite its benefits and legal support, we observe that it does not occur on a regular and systematic basis. In our study, the accompanying person was present only in 40.6% of deliveries, more frequently with women receiving care in the private health care system, in the capital, with a higher education level and lower parity. Data from the "Birth in Brazil" study allowed for finding similar results as independent predictors of having no accompanying person: lower income and education, brown skin color, being a user of the public health care system, multiparity and vaginal delivery.26 This demonstrates the need to raise awareness about this right and its importance by professionals providing prenatal care in the public health care system, in order for all parturients to benefit from it.

Although there is evidence that the routine use of episiotomy does not present short- or long-term benefits for parturients when compared to its restrictive use,2,10 the frequency of this intervention was 40.6%, well above the 10% recommended by the WHO4, and more frequent among younger women. The frequency of episiotomy in primiparous women was 71.4%, but, given their small number, there was no significance following variable adjustment. A cross-sectional study carried out in Spain with 12,093 women also showed an episiotomy rate as high as 50%. The variables that presented a significant association were primiparity (RR=2.98), gestational age greater than 41 weeks (RR=1.2), induced labor (RR=1.33), analgesia (RR=1.95), use of oxytocin (RR=1.58), delivery in the lithotomy position (RR=6.4) and instrumental delivery (RR=1.84).27

In a teaching-maternity hospital in Recife, in Brazil's northeast, where the adoption of good practices is systematic, there was a reduction in episiotomy rates from 29% in 201028 to 10% in 2014.29 A case-control study undertaken at this institution showed that the factors most frequently associated with this procedure were physician-assisted births, primiparity, and instrumental births.29 We may thus conclude that continued medical education, inclusion of the nursing staff in childbirth care, adoption of good practices, and reduction of interventions during labor and delivery result in a reduced number of episiotomies being performed.

There is insufficient evidence to support the routine use of a partogram to manage labor.9,30 However, considering that some studies have shown benefits from using them, particularly at institutions with fewer resources,30 the National Directive for Normal Labor Care recommends using the model with a 4h-action line routine.2 In our study, the more frequent use of a partogram and eating being allowed during labor among women with high-risk pregnancies can be explained by the fact that there is only a single high-risk maternity hospital in the state of Sergipe, which also serves as a center for medical residency and obstetric nursing services, where good care practices are more frequent.

A qualitative, exploratory and descriptive study carried out at a maternity hospital in southern Brazil showed that some practices that are detrimental to the patients' health are still used by professionals who perpetuate previously learned, inadequate models. Such models are expected to make the moment of delivery easier, but without evidence-based justifications for adopting them.31

Because this is a cross-sectional study, we could not conduct a time-trend analysis. Nevertheless, since it included a representative number of patients from the entire state, this is an adequate overview of what happens in Sergipe. Studies that can prospectively evaluate pregnant women during pregnancy until delivery could be more elucidative. Those who can assess the motivations of the agents involved can also identify the reasons for the disparities in care.

In conclusion, in the state of Sergipe, the factors most frequently associated with cesarean section were receiving care in the private health care system, having a greater length of education and having a high-risk pregnancy. Patients in the public health care system and with a lower education level have less access to labor analgesia and to the presence of an accompanying person. It is observed that obstetrical good practices are not universally used and unnecessary interventions, which are still frequent, should be discouraged.

Changes in paradigms, in general, occur gradually. Obstetric care in Brazil remains, in several places, based on "tradition". The importance of encouraging the adoption of scientific, evidence-based protocols in all maternity hospitals, continuing medical education and conducting audit of health care services becomes clear. Accordingly, we suggest that studies evaluating the satisfaction degree of puerperal women with the care received be conducted, comparing different practices that may serve as a stimulus for implementing the necessary changes in behavior.
