minimal medical standards, or both [2,3].Fourteen percent of all unsafe abortions in low-and middle-income countries are among women aged 15-19 years.About 2.5 million adolescents have unsafe abortions every year, and adolescents are more seriously affected by complications than older women [4].Deaths attributed to unsafe abortions in developing countries are estimated at 80,000 annually, i.e. 400 deaths per 1,00,000 abortions.Each day 192 women die because of complications associated with unsafe abortions which amount to one woman every eight minutes, all of them in developing countries [5].
The Penal Code of Bhutan states that abortion is illegal except when it is conducted to save the life of the mother or when the pregnancy is a result of rape, or when the mother is mentally unsound [6,7].In 1999 the Ministry of Health and Education legalized the "Medical Termination of Pregnancy" (MTP).To carry out medical termination, the certification of two medical doctors is required.However, the number of abortion for medical reasons is minimal according to hospital sources [8].Its incidence is expected to be low considering that there is still a strong adherence to Buddhist beliefs and given society's acceptance of children born out of wedlock.However, according to some studies, over the years a growing number of Bhutanese women are seeking unsafe abortion in the neighbouring areas of India [6,8,9].Obtaining accurate data for abortions is challenging, and especially so for unsafe induced abortion [7,10].
In Phuentsholing General Hospital (PGH), women seeking treatment for complications associated with unsafe abortion were seen routinely.Therefore, the aims of this study were to understand the trend and burden of abortions and factors associated with an abortion amongst women attending PGH.Additional aims were to determine the contraceptive use and underlying reasons for not using contraceptives.

Introduction
It is estimated around 42 million women worldwide seek an abortion for unintended pregnancy each year, and 20 million resort to unsafe abortions with 98% of them in developing countries [1].Unsafe abortion is defined as a procedure for terminating an unintended pregnancy carried out either by persons lacking the necessary skills or in an environment that does not conform to largest city in Bhutan.It is located 171 km south of Thimphu, and is the commercial hub of Bhutan.Indian town of Jaigaon located next to Phuentsholing allows easy access for a variety of reasons including employment, commercial and entertainment purposes to name a few.PGH is a 50 bedded hospital, with specialist services in General Surgery and Obstetrics and Gynaecology, besides the general care of the patients.The hospital caters to the people of Phuentsholing Town and other sub-districts of Phuentsholing, and Sampheling (Figure 1).PGH serves as the referral centre for gynaecological services from the neighboring health centres of Gedu Hospital (Chukha Dzongkhag), Samtse Hospital, Gomtu Hospital and Sibsoo Hospital under Samtse Dzongkhag, and Lhamozingkha BHU I under Dagana Dzongkhag.The total population of Phuentsholing for the year 2015 was approximately 24,721 [11,12].

Retrospective study
The retrospective study was conducted to understand the trend of abortion from all causes in PGH from 1 st January 2008 to 31 st December 2011.The data was extracted by two researches (KW and MRG) from admission forms of admitted patients and monthly morbidity reporting forms from the hospital data repository and crossed checked with the District Health Office (DHO) data base to validate the completeness of data.The data extracted were monthly reported abortions from all causes and sub-divided into Outpatient Department (OPD) patients and In-Patients.

Prospective study
The prospective study was conducted from 1 st March 2012 to 28 th February 2014 using a questionnaire.Based on other published studies, a standard questionnaire was modified into four parts with both closed and open-questions [13,14].The part one of questionnaire related to demographic information of the participants; and part two related to reasons for undergoing abortion and methods used for abortion.Parts three and four of questionnaire were on outcome and complications of abortion and contraceptive information, respectively.
Attempts were made to administer the questionnaire to all the patients seeking abortion associated care in PGH: In-patient, Emergency Department and patients attending OPD.Patients who consented to participate in the study were included in the study after consent forms were signed.The questionnaire was administered to the participants by the female nurses of PGH.The interviewers were given one day training on administering the questionnaire.The outcome of the abortion was obtained for each participant from the admission and discharged forms.

Statistical Analysis
Descriptive statistics (frequencies and mean) was used to describe the demographic characteristics and outcome of the event.The types of abortion were stratified by potential covariates and compared using Pearson's chi-squared test.Bivariate and multivariable logistic regression was used to examine the independent correlates with induced abortion built using backward elimination to identify significant covariates.An alpha value of 0.20 was used to determine which variables remained in the model.A value of p ≤ 0.05 was considered significant.Data analysis was carried out using STATA Intercooled 10.Ethical approval for this study was provided by the Research Ethics Board of Health (REBH), MoH, Royal Government of Bhutan (reference number: REBH/Approval/11/018).Written informed consent was obtained from every respondent.Interviewers explained the general purpose, benefits, and any risks of the survey to each respondent in his or her local language, and respondents had the right to refuse participation in the survey at any point.

Retrospective study
The retrospective study of four years showed that on an average, 9.75 cases per month (range 3-16) reported to hospital for abortion associated care.During this period, the highest cases were reported in 2008 with 125 cases (mean-10.42)and the lowest in 2011 with 108 cases (mean-9) (Table 1).The trend of abortion continued to be constant throughout year (Figure 2).

Prospective study
Socio-demographic characteristics: A total of 77 patients were recruited for the prospective study over two years from 1 st March 2012 to 28 th February 2014.This included both induced and spontaneous abortions.The median age of the patients was 26 years (range 18-42 years).Most of the patients were older than 25 years accounting up to 57.1% (44).Primary or secondary level educated women made up the most patients 45.4% (35) followed by those women with no formal education at 39.0% (30).A majority of patients were married 93.4% (71); house wife and private employee made up the most patients at 59.7% (46) and 28.6% (22), respectively.More than forty eight percent (37) of participants had 1-2 children, 34.2% (26) did not have any children.Of those who had children, 38.7% (27) of the children were in the age range of 1-5 years.Most of the women were one to two months pregnant.The commonest method of abortion amongst those who induced abortion was taking medicine (85.2%) (Table 2).

Contraceptive use and types of abortion:
Two third of the study participants used contraceptives 67.5% (52).The most common type of contraceptive was injectable contraceptives followed by oral contraceptive, 48.1% (25) and 32.7% (17) respectively.Nearly half of the respondents, 41.9% (33) reported that quality of contraceptive services were good while 24.7% (19) reported the services were  excellent.More than 22.0% (17) failed to give any reasons for not using contraceptive.Half of the participants 49.4% (38) said that abortion should not be legalized as a form of contraceptives, 32.5% (25) were unsure whether abortion should be legalized, however, 15.6% (12) responded that abortion should be legalized (Figure 3).
The commonest type of abortion was spontaneous abortion (abortion that occurred naturally without medical or surgical intervention) followed by induced abortion (both medical and surgical outside the hospital) at 59.7% (46) and 35.1% ( 27) respectively.The commonest outcome of the abortion was uneventful at 62.3% (48).In 31.2% (24) of participants had excessive bleeding (> 500 ml) and only one patient had serious complication of sepsis and shock (1.3%) due to spontaneous or induced abortion outside hospital.A very few participants 7.4% (2) each stated that contraceptive failure was the

The main reasons for induced abortion were family being complete, not ready to start a family, and focus on education [25][26][27].Even though the contraceptive use among the participants was 67.5%, women failed to avail contraceptive services which are offered free of cost in Bhutan.Generally, contraceptive rate in Bhutan stands at 65.6% for 2011 [28].Present study did not explore the reasons for low contraceptive use in PGH.However, it has been highlighted in literature that the main reasons teenager did not use contraceptive services was due to the attitude and responses from the service provider [29].Despite offering free contraceptives in Bhutan, the accessibility may be one of the main barriers for availing the services.The free contraceptives in the hospitals and health centers have limited hour of services, opening from 9:00 AM and closing at 3:00 PM.Similarly, emergency contraceptive such as pills over morning are available but restricted in the hospitals only (personal communication).These services are not provided during the other times except for the condoms which are provided at many locations such as hotels and other public places.However, the availability of condoms is not monitored regularly.Improvement in access to emergency contraceptives could reduce unwanted pregnancy and thereby unsafe abortion.
Married women were less likely to undergo induced abortion as compared to those who are single, student, living together and divorcee in this study, which is in agreement with number of studies but contradicted a study from Ghana [30][31][32][33].This finding of women in non-marital unions is more likely to choose induced abortion because single women have options when faced with unplanned pregnancies.The month of pregnancy was significant factor in multivariate analysis.As the pregnancy progressed the risk of induced abortion decreased.This could be as a result of complications associated with undergoing abortion as the pregnancy progressed [34].
The study has various limitations.Firstly, due to small number of study participants the power of study was weak.Secondly, interviewer being the nurses from the hospital introduced interviewer bias.Thirdly, all cases of abortion could not be recruited because of the heavy clinical works and responsibilities.Despite the limitations, this study shows that there are significant numbers of women undergoing induced abortion.Therefore, it is recommended to conduct similar study in other hospitals to find out the true burden of induced abortion.

Conclusions
There were significant cases of abortion from all causes that reported to PGH for abortion associated care.The common types of abortion were spontaneous abortion followed by induced abortion.The main reasons for induced abortion were completion of family and not ready to have another child.The commonest complication was loss of blood more than 500 ml.Also use of contraceptives among the study population was higher than the contraceptive rates of Bhutan.

Discussion
Abortion from all causes have increased during the study period in Bhutan from 928 to 1190 [8,[15][16][17].However, there was fluctuation of abortion cases in PGH with highest reported in 2010 and lowest in 2009.In 2010, PGH treated about 10% of total abortion cases in the country.This could be as a result of induced abortion in Indian town of Jaigon because abortion as a form of contraceptive is illegal in Bhutan.In our study more than half of the women were admitted for induced abortion with some complications such as bleeding and internal injury.These complications can lead to abortion-related morbidity [18,19].The morbidity due to unsafe abortion, particularly in developing countries, results in a heavy burden on women, their families and the health care system [20,21].Restrictive laws on abortion also inhibit people from seeking medical care.Despite significant annually reported abortion from all causes in PGH from 2008-2011, the study failed to enrol adequate number of participants.One of the possible impediments in enrolling participants in the study was due to the social stigma associated with abortion.Secondly, undergoing abortion is seen as morally incorrect and religiously sinful, given large proportion of Bhutanese are Buddhists.Social and cultural beliefs against abortion are other
