Introduction

• Spontaneous abortions can be occur in every pregnant women especially in the first trimester that was found about 25-50% (Jana L Allison, MD, et al, Management of First Trimester Pregnancy Loss Can Be Safely Moved Into the Office, Rev Obstet Gynecol.2011; 4(1): 5-14)

• More than 80 % of Spontaneous abortion occur in the first trimester and most of Spontaneous abortions need to terminate of pregnancy such as inevitable abortion, incomplete abortion, missed abortion, and septic abortion (Teera Tongsong, 2541)

Introduction

• Abortion has been understood by many as termination of unwanted pregnancy. Article 305 of Thai Penal Code states that abortion is illegal except in cases when it is committed by a medical practitioner and is considered only as necessary if the same endangers the health of the mother or when the pregnancy is due to sexual offences such as rape and incest

(Article 305 of Thai Penal Code )

Introduction

• About the study, carried out in Thailand in 1999 in 787 government hospitals, examined the magnitude and profile of abortion in Thailand, using data collected prospectively through a review of 45,990 case records (of which 28.5% were classified as induced and 71.5% as spontaneous abortions) and face-to-face interviews with a sub-set of 1854 women patients. Socio-economic reasons accounted for 60.2% of abortions and Medical indications accounted for 30.8%.

(Family Planning and Population Division , Department of Health, Ministry of Public Health)

Introduction

• The methodology to termination of pregnancy has a lot of methods for example expectant, medical treatment, and surgical treatment(Jana L Allison, MD, et al, Management of First Trimester Pregnancy Loss Can Be Safely Moved Into the Office, Rev Obstet Gynecol.2011; 4(1): 5-14)

• The study about the outcome of medication and aspiration for terminating the pregnancy in first trimester , was found both methods was highly successful and low complication (Ian M. Bennett, MD, PhD et al, Early Abortion in Family Medicine: Clinical Outcomes, Ann Fam Med. 2009 November; 7(6): 527–533.)

Introduction

• The study, which compared the cost-effectiveness of MVA, Misoprostol, and Curettege was found MVA is the most effective method with the least complications and cheapest. (D Hu, D Grossman, C Levin, K Blanchard, SJ Goldie , 2009)

• This research is to compare the cost-effectiveness of methods for terminating abnormal first trimester pregnancy among indicated patients at Naresuan University.

Objective

Discussion 1

The results of studying the characteristics of pregnant women who terminated their pregnancy no difference of average age all 3 methods

because termination of pregnancy does not depend on age but it depends on the decision of physicians and patients

no gold standard to terminate in the first trimester pregnancy.

Discussion 2

The number of pregnant times (gravida) no different results.

because the most of pregnant women in these three groups were the first pregnancy.

but previous abortion when it was compared with these three methods were found that there were a statistical difference.

This might be obviously caused by the more times of abortion in those who were terminated by Curettage than the other methods.

Discussion 3

The results of termination of pregnancy when they were compared to the completion of pregnant termination from these three methods were found that there were a significantly statistic difference.

The completion of Curettage was 100%.

May be In case of failure in the other methods, the pregnancy will be continued to terminate by Curettage.

However, there were no difference between the completion of pregnant termination by Misoprostol and MVA.

Discussion 4

The results of pregnant termination, when they were compared with the complications after these three pregnant termination methods no statistical difference.

However, Misoprostol method had more chances to incomplete abortion than the others.

The reasons for no statistical difference of complications after these three pregnant termination methods were the analysis of complications was summation of the number of all complications.

Discussion 5

The expenses for the termination with these three pregnant termination methods no statistical difference.

because the first method, misoprostol, cannot be supposed to be completed. When the first method was failed procedure, there was further procedure; that was curettage, this can increase higher expenses.

However, if the first method, misoprostol, was completed, the expenses will be significant different.

Discussion 6

The duration of procedures compared with these three

pregnant termination methods statistical difference.

It was found that MVA, Curettage, and Misoprostol take the

least time, respectively.

Discussion 7

This study show the retrospective cohort study was considered

by gathering secondary data from medical records and delivery

room. Incomplete medical records

information bias.

To decrease bias, the study should be designed as prospective

cohort study.

Conclusion

The pregnant women in the first trimester of gestation age with abnormal pregnancy who plans to terminate pregnancy

should use curettage method because it is the most effective method with the least complications and no highly different expenses when it is compared with the other methods.

Recommendation

• Type of this research is retrospective cohort study. Data is getting from medical records only.

• If have a chance, we plan to do randomized control trial study, that can determine exactly variables and characteristics, prevent of selection bias and other confounds and study in large population.

• we need more details in complication and medical fee should be seperated such as procedure cost, medication cost.
