Abstract

Background: Obstructed labor is still major cause of maternal morbidity and mortality, and adverse birth out comes in low income countries. The issue of obstructed labor is unsolved problem in Ethiopia so far.
Objective: This study aimed to assess magnitude and factors associated with obstruct labor among women delivered at Halaba Kulito Primary Hospital, Halaba Special District, Southern Ethiopia.
Methods: A hospital based cross-sectional study was employed from March 1-21, 2015 at Halaba Kulito Primary Hospital. Systematic sampling technique was used to select 344 deliveries from delivery registration book. A pretested checklist was used to retrieve data from delivery card of the women. Data were entered Epi data version-3.1 and analyzed using SPSS version-21 software. To identify independent factors, bivariate and multiple binary logistic regressions were undertaken. A p-value<0.05 was used to determine association between variables was considered
statistically significant.
Results: The magnitude of obstructed labor was 18.6%.The following factors were significantly associated with obstructed labor:o-antenatal care follow up (AOR=3.1, 95% CI:1.5, 6.4), women age less than 20 years (AOR=6.9, 95% CI (2.2, 21.6) and malpresentation (AOR=10, 95% CI: 3.7, 27.5).
Conclusion: Obstructed labor was very common in the study area. Antenatal care visit, maternal age and malpresentation were associated factors of obstructed labor. To reverse obstructed labor related problems, overall improvement in antenatal and intrapartum care.

Introduction

Obstructed labor is one where in spite of good uterine contractions, the progressive descent of the presenting part is arrested due to mechanical obstruction. This may result either due to factors in the fetus or in the birth canal or both, so that further progress is almost impossible without assistance [1].

Obstructed labor is one of the common causes of maternal, perinatal morbidity and mortality in low income countries [2-6].

Worldwide the incidence of obstructed labor varies between 3%-6%. The lower figure was applied in more developed regions and the higher figured to less developed areas. It is responsible for about 9% of maternal death. Which is varies region to region 4.1% to all maternal deaths in Africa; for Asia this amounted to 9.4%and 13.4% for Latin America and the Caribbean.

In contrast most maternal deaths in developed countries are due to other direct causes, mainly complications of anesthesia and Caesarean sections [7]. In Ethiopia as observed in different studies from across the country the prevalence of obstructed labor is estimated between as low as 4.1% [8] and as high as 34.3%) [9].

Women who had obstructed labor have an elevated risk of ruptured uterus, puerperal sepsis and postpartum hemorrhage [3,4,6,10,11]. It also causes severe and distressing long-term complications like obstetric fistula (which is most severe and distressing long-term condition) and intrauterine infections following prolonged rupture of membranes [4,12].

In addition, place financial and emotional burdens on families and communities as whole due to hospitalization [13]. Moreover, trauma to the bladder during vaginal or instrumental delivery may lead to stress incontinence [6,10].

If the duration of obstructed labor is prolonged without intervention, the fetus dies because of anoxia by excessive pressure on the placenta and umbilical cord.

Obstructed labor also has consequences for the fetus or neonatefrequent results in asphyxia, that can result in stillbirth, neonatal demise, intracranial hemorrhage, cerebral palsy, and developmental disability, due to severe molding of the head leading to tentoria tear or traumatic delivery, caput, fetal distress, and acidosis due to fetal hypoxia and maternal acidosis and neonatal sepsis [2-6,8,14].

Empirical evidence from many different cultural settings have identified several associated factors of obstructed labor including: living environment, parity (primipara and grand multipara, age between 15-19 [15,16], pervious history of obstructed labor [15], malpresentation [16,17] and birth weight >4 kg [16,17].

Ethiopia has applied a multi-pronged approach to reduce maternal and perinatal morbidity and mortality by improving access to and strengthening facility-based maternal and newborn services [18]. Despite of this obstructed labor seems to be a common cause of maternal and perinatal morbidity and mortality in Ethiopia [19-22].

So the need of further study is absolute to recognize the magnitude and factors of obstructed labor. Therefore, this study aimed to assess the magnitude of obstructed labor and its associated factors among women delivered at Halaba Kulito primary Hospital, Southern Ethiopia.

Methods and Materials

The study was conduct in Halaba Kulito Primary Hospital is located in southern Ethiopia in Halaba special Woreda which found 203 km from Addis Ababa and 90 km from regional town, Hawassa. Halaba Kulito Primary Hospital is the only Hospital found in the Halaba Kulito, town of Halaba special district. It serves for 85000 people residing in urban and rural parts of southern Ethiopia.

The hospital has four wards (medical, pediatric, surgical, gynecology and obstetrics) and 1 emergency, 3 outpatient departments, maternal and child health care, antiretroviral treatment, ophthalmology and dentistry departments.

According to deliver register book from January 1, 2016 to December 1, 2018 delivery report 3329 mothers were delivered in this Hospital. The study was conducted from March 1-21, 2018.

A Hospital based retrospective cross-sectional study was employed. The source populations for the study were all cards of mothers who were gave birth from January 1, 2016 to December 1, 2018 at Halaba Kulito primary Hospital.

Study population were selected cards of mothers who were gave birth from January 1, 2016 to December 1, 2018 at Halaba Kulito primary Hospital. Mothers cards were missing of most information (incomplete) (delivery summary, labor History and Physical examination and lab investigation) were excluded.

The sample size was determined with Single population formula and calculated by using EPI INFO version-7 software.

The following assumptions were used to estimate the sample size; the proportion of obstructed labor was taken from the study conducted in Harerghe Zone 34.3% [9], with 95% confidence interval, desired precision 5%, and 10% missed items, the final sample was 344 cards. To obtain study subjects systematic sampling technique was employed.

First sampling frame was developed by using maternity (delivery) resister book from January 1, 2016 to December 1, 2018 before actual data collection period. Then k-value was calculated by dividing total deliveries (3329) to required sample size.

Data were collected by using a pre-tested checklist from maternal cards. The checklist was developed based on instruments that were applied in other related studies [8-19,23-26]. Obstetric related characteristics and medical illness.

Data were collected by four midwives.To ensure the quality of data to be collected from the mothers card, first, data collection checklist was pretested on 17 mothers cards and necessary modifications were made based on the nature of gaps identified in the checklist.

Data collectors were trained for one day intensively on the study instrument and data collection procedure that includes the relevance of the study. The data collectors were worked under close observation of the supervisors to ensure reliability to correct data collection procedures.

In addition, supervisors and investigator checked the filled questionnaires at the end of data collection every day for completeness. Furthermore, the data were carefully entered and cleaned before the beginning of the analysis.

Data were entered using Epi data version-3.1 and exported to Statistical Package social science (SPSS) version 20 for analysis. Descriptive statistics was computed to determine the magnitude of obstructed labor and other factors. Binary logistic regression analysis was used to identify factors associated with obstructed labor.

First a bivariate logistic regression was carried out to select candidate for multivariable logistic regression analysis. Variable with p<0.25 in bivariate logistic regression was selected for multivariable logistic regression.

Multivariable logistic regression was done for variables that have pvalue <0.25 during the bivariate logistic regression analyses to identify factors associated with obstructed labor and to control for potential confounders.

The degree of association between independent and dependent variables were assessed using odds ratio with 95% confidence interval. P-value<0.05 was considered as statistically.

The Hosmer-Lemeshow goodness-of-fit statistic was used to check if the necessary assumptions for multivariable logistic regressions were fulfilled and the model had p-value >0.05 which proved the model was good.

Before actual data collection formal letter of permission was obtained from Wachemo University College of Medicine and Health Sciences. In addition, letter of permission was secured from Halaba Kulito Health office and Hospitals Management committee. Confidentiality of information was maintained.

Table 5: Bivariate and multivariable logistic regression of selected variables in relation to obstructed labor among deliveries at Halaba primary Hospital January 1, 2016 to December 1, 2018.

Mothers who didn’t have antenatal care follow up were nearly 3 times more likely to have obstructed labor than mothers who had antenatal care follow up (AOR=3.1, 95%CI (1.5, 6.4)). The presence of any form of malpresentation to labor were 10 times more likely to have obstructed labor than their counterparts (AOR=9.2, 95% CI (3.3, 25.6).

Additionally, mothers age less than 19 years were nearly 7 times more likely to have obstructed labor than their counterparts (AOR=6.9, 95%, CI (2.2, 21.6)).

Discussion

In the present study the magnitude of obstructed labor is 18.6%. The prevalence of obstructed labor found in the present study is relatively similar to that reported in the Hospital based study conducted at Gimbi Hospital (18.1%) [16]. However, this study found out a higher prevalence of obstructed labor compared to other Hospital based study in, Ilu Ababora Zone, Adama, Jimma and Mizan where 4.1%, 9.6%, 12.2% and 7.95% respectively [8,17,25,26].This variation may be due to difference in the skills of data collectors, study area and methodology. And it is lower than study West Harerghe Zone 34.3% [9] and Nigeria (20.5%) [23]. This difference may be explained by the difference in study setting and may be due to various intervention undertaken between these study time.

This finding was high as compared with the research done in Uganda and Pakistan where 10.5% and 5.2% respectively [15,27]. This difference is explained by the difference in study area, sample size, time gap, cultural difference and utilization of health care services between those studies.

As revealed by the present study,antenatal care visit was found to have significant association with obstructed labor. This may be attributed to the beneficial impact of antenatal care visit on pregnancy outcome, either through the detecting and help to ensure early interventions, thus those mothers at risk of obstructed labor. This is again supported by a research done in in Nigeria which revealed that mothers who didn’t attend antenatal care visit were more likely to experience obstructed labor compared with those mothers who had antenatal care visited [23]. Obstructed labor also found to be associated with age of mothers less than 19 years in this study. This finding was almost found to be a universal fact and has been revealed in many studies [15,16].

In present study, malpresentation was significantly associated with obstructed labor. This finding was almost found to be a universal fact and has been revealed in many studies [3,4,15,17] and texts [1]. This study clearly shares the limitations of cross-sectional studies and the retrospective nature of the study and lack of some important variables due to inappropriate and/or non- recording of certain variables.

Conclusion

The Magnitude of obstructed labor was very common in study area. Findings indicated that no antenatal care visit, age between 15-20 years and malpresentation were significantly associated with obstructed labor. In general, highest results of this study to earlier studies show ineffectiveness of existing national programs for improving the maternal care. To reverse obstructed labor related problems, overall improvement in antenatal and intrapartum care. So it is essential to provide the necessary facilities for maternal health at both the community and the health system level.
