ABSTRACT

OBJECTIVE: To characterize the profile of individuals who were unable to obtain the surgical contraception procedure, and associated factors.
METHODS: This was a cross-sectional study conducted in Ribeirão Preto (Southeastern Brazil) in 2004, on 230 individuals who were unable to obtain sterilization surgery through the National Health System (SUS) between 1999 and 2004. A questionnaire on sociodemographic information, use of contraceptive methods, aspects of sterilization and desire to undergo sterilization in the future was applied. The variables of sex, age, religion, per capita income, marital status and schooling level were compared between the total number of individuals who were unable to obtain this procedure and 297 individuals who were sterilized.
RESULTS: Among the 230 interviewees, 21.3% were men and 78.7% were women. Most of them were married, white and Catholic and had had at least four years of schooling. The median monthly per capita income was R$ 140.00. Twenty-three of them (10%) had hopes of undergoing the operation. The remaining 207 were classified in two groups: 71% had decided to postpone the operation and 29% had faced obstacles in relation to gaining access to sterilization. The latter group was associated with being female, young and black. After logistic regression, being black was the only factor that remained associated with inability to obtain sterilization. Comparison with individuals who were able to obtain the procedure showed that being female, older, evangelical and single were associated with inability to obtain sterilization, while higher income and schooling levels favored access.
CONCLUSIONS: Few of the individuals studied had not had access to sterilization. Most had postponed the procedure and a smaller proportion had encountered institutional obstacles. Blacks encountered more barriers than whites did.

RESUMEN

OBJETIVO: Caracterizar el perfil de individuos que no obtuvieron el procedimiento de contracepción quirúrgica y factores asociados.
MÉTODOS: Estudio transversal realizado en Ribeirão Preto (Sureste de Brasil), en 2004, con 230 individuos que no obtuvieron cirugía de esterilización en el período de 1999 a 2004 por el Sistema Único de Salud. Fue aplicado un cuestionario con informaciones sociodemográficas, uso de métodos anticonceptivos y aspectos de la esterilización y deseo de esterilizarse en el futuro. Fueron comparadas las variables sexo, edad, religión, renta per capita, estado marital y escolaridad del total de los que no obtuvieron el procedimiento con 297 individuos esterilizados.
RESULTADOS: De los 230 entrevistados 21,3% eran hombres y 78,7% mujeres. La mayoría era casada, blanca, católica y tenía por lo menos cuatros años de estudio. La renta per capita mediana mensual fue R$ 140,00. De los entrevistados, 23 (10%) tenían expectativa de hacer la cirugía. Los restantes 207 fueron clasificados en dos grupos: 71% decidieron posponer la cirugía y 29% encontraron obstáculos en el acceso a la esterilización. El segundo grupo fue asociado a ser mujer, joven y negra. Posterior a la regresión logística, ser negro fue el único factor que se mantuvo asociado a la no obtención de la esterilización. Al comparar con el grupo de los que obtuvieron el procedimiento, pertenecer al sexo femenino, ser mayor de edad, tener como religión la evangélica y ser soltero estuvo asociado a la no obtención de la esterilización, mientras que mayor renta y mayor escolaridad favorecieron el acceso.
CONCLUSIONES: Pocos individuos estudiados no tuvieron acceso a la esterilización, sobretodo por haber pospuesto ese procedimiento y una menor parcela tuvo obstáculos institucionales. Los negros encontraron más barreras que los blancos.

INTRODUCTION

Contraceptive care is an important component of primary healthcare and provision is made for this in the Ministry of Health's policy for comprehensive women's healthcare. This policy covers clinical-gynecological care from adolescence to the menopause; prenatal, delivery and postnatal care; gynecological cancer prevention; and prevention and treatment for sexually transmittable diseases, including HIV/AIDS.

According to law 9.263a and the Ministry of Health's ordinance 144,b the Brazilian National Health System (Sistema Único de Saúde, SUS) must offer all contraceptive methods, including surgical sterilization, with adequate counseling.

In Ribeirão Preto (Southeastern Brazil), surgical sterilization through SUS started to be offered in 1999. This provision consisted of several actions, including establishing a maternity hospital as a referral center that was properly certified to carry out sterilization surgery (vasectomy and tubal ligation), and a process of continuing capacitation for health professionals within the primary healthcare network, so that they could give guidance and counseling regarding contraception.c

Five years after implementation, an assessment was conducted on various aspects of the provision of surgical methods,c with the aim of improving the quality of the service. According to Bruce2 (1990), improvement of the service produces a clientele that adheres better to the use of contraceptives in family planning and is more committed towards and satisfied with their use.

This assessment took into account access to and satisfaction with the counseling and sterilization, the presence of pelvic pain and the degree of sexual satisfaction among sterilized women.5 Among the preliminary results, it was concluded that some of the individuals who had asked for sterilization through SUS in Ribeirão Preto did not obtain the procedure.c The reasons for not obtaining it might be related to giving up the idea of the operation or postponing it, consequent to counseling, or they might be related to obstacles due to failings of the healthcare system.

The aim of the present study was to characterize the profile of individuals who did not obtain the surgical contraception procedure within SUS and factors associated with this.

 

METHODS

This was a cross-sectional study conducted in Ribeirão Preto (Southeastern Brazil) on individuals who had sought surgical sterilization through a primary healthcare unit (PHU) between October 1999 and May 2004, but did not obtain it. Their names appeared in an index book for candidate registrations, but not on a list of individuals who underwent the operation up to May 2004, supplied by the referral center. There were initially 2,631 registrations in the index book, and these individuals were identified by four research assistants over a four-month period (May to August 2004). Starting from the record of the procedure in the index book, the candidate's name was checked on two specific lists: the vasectomy and tubal ligation lists. If neither the candidate's name nor the partner's name appeared on these lists, the names and personal data were checked in the Municipal Health Department's computerized system (Hygia) to confirm whether there was an entry in the system. In cases of the same name or incomplete names, confirmation was sought through other data (date of birth, parents' names or partner's name, among others).

Out of a total of 392 names identified in the index book, of individuals who did not obtain the procedure (14.9%), 230 (58.7%) were interviewed, 148 (37.8%) could not be found and five (1.3%) had died between 1999 and 2004. Nine (2.3%) refused to participate in the study, of whom five said they had never sought the sterilization service.

The interviews were conducted in the participants' homes, by means of a questionnaire containing 41 questions divided into three sections: sociodemographic information, use of contraceptive methods and factors relating to sterilization (reasons for not undergoing sterilization, satisfaction with the counseling) and remaining desire to undergo sterilization. In an open question, the interviewees were asked to indicate the positive and negative points in their counseling. They were also asked whether they had received the hospitalization form that would allow them to arrange a date for the surgery.

The questionnaire was pretested on SUS users. The interviews for the study were held between August and December 2004, and the interviewees had received prior training. Up to three attempts to find individuals in their homes were made. Forty-seven interviews (20% of the questionnaires) were randomly reapplied for quality control purposes.

The characteristics of the candidates who did not obtain the procedure and the reported reasons for this were analyzed using the chi-squared test. The variables were evaluated by means of multiple logistic regression in order to identify the risk of impediments to the operation.

The variables of sex, age, religion, per capita income, marital status and schooling were compared between the individuals who did not obtain the procedure and a group of 297 sterilized individuals from a sample of 336 candidates for surgical sterilization.c

This study was approved by the Research Ethics Committee of the Centro de Saúde Escola da Faculdade de Medicina de Ribeirão Preto (Health Center School of the Ribeirão Preto School of Medicine), University of São Paulo (Protocol no. 0066/03). The participants signed a free and informed consent statement.

 

RESULTS

Out of the 230 individuals interviewed, 49 (21.3%) were men and 181 (78.7%) were women. Their mean age at the time of requesting sterilization was 31.9 years for the women and 34.4 years for the men.

A majority of them (107; 46.5%) were formally married, while 75 (32.6%) were cohabiting. Only 24 (10.4%) were single, 19 (8.3%) were separated or divorced and five (2.2%) were widowed.

In relation to skin color, 112 (53.0%) said that they were white, 78 (33.9%) mixed (black and white) and 29 (12.6%) black, and only one individual self-reported as Asian.

With regard to schooling, four (1.7%) were illiterate, 28 (12.2%) had not completed primary education (years 1 to 4), 108 (47.0%) had completed four years of education, 62 (27.0%) had completed eight years of elementary education, 26 (11.3%) had concluded high school education and only two (0.9%) had concluded university-level education.

Concerning socioeconomic condition, the Brazilian criteria were used.d These combine schooling level with the presence of consumer goods in interviewees' homes in order to classify them into five groups. The majority of the interviewees (138; 60%) were classified in category D, while 79 (34.4%) were in category C, eight (3.5%) in category B and five (2.2%) in category E.

The mean monthly family income was R$ 720.55, with a minimum of R$ 50.00 and a maximum of R$ 3,000.00. Five interviewees stated that their families did not have any income. The mean monthly per capita family income was calculated as R$ 177.50, with a minimum of R$ 7.78 and a maximum of R$ 666.67. The median monthly per capita income was R$ 140.00. With regard to religion, 137 (59.6%) said that they were Catholics, 77 (33.5%) evangelicals and seven (3.0%) spiritualists, while four (1.7%) had other religions and five (2.2%) said that they did not have a religion.

The number of members of the family living in the same household ranged from one to 15 (mean and median of five). The number of children still alive ranged from one to 14, with a mean of 3.3 and median of 3.0. One interviewee said that he did not have any children that were alive.

The reasons for not obtaining surgery are presented in Table 1. Among the reasons, 23 individuals (10%) said that they were still waiting to be called. The remaining 207 individuals were divided into two groups: the first group (147/71.0%) gave reasons for voluntarily giving up the idea of surgery or postponing it; while the second group (60/29.0%) gave reasons outside of their control for not obtaining the procedure. Out of the 147 individuals who gave reasons for not undergoing the operation, 34 (23.1%) mentioned the definitive nature of the operation and that they were too young to make such a decision, 42 (28.6%) said that they had not had time available for undergoing the operation; 39 (26.5%) said that they were afraid of surgery; five (3.4%) had broken up with their partners during the counseling process; four (2.7%) had decided to use other methods; nine (6.1%) mentioned health problems and 14 (9.5%) presented other reasons.

 

 

Among those who said that they were afraid of surgery, most of them indicated the risks of anesthesia or fear of pain or complications. Only two men mentioned fear of sexual impotence.

Among those who gave other reasons, the following were cited as impediments: inability to take time off work to undergo the surgery, getting the dates mixed up, losing the appointment card, accidentally tearing up the referral form, moving to another city and religious reasons, among others.

Out of the 16 (7.7%) interviewees who mentioned that a health problem had stopped them from having the operation, nine (56.3%) were allocated to the first group, because they had been examined by a physician and had received the form for the surgery. The remaining seven were allocated to the second group.

The second group was formed by 60 individuals (29.0%), who indicated the following other reasons for the decision not to undergo sterilization: 13 (6.2%) reported problems relating to the healthcare system, 11 (5.3%) were forbidden to do it by their partners and four (6.7%) became pregnant during the process. Twenty-five individuals (12%) who underwent the operation at another place because of dissatisfaction with the service were included in this group.

Among the problems with the healthcare service that stopped these individuals from having the operation, the following were cited: delay in making an appointment for the surgery, lack of physician on the day of the operation, breakdown of the laparoscopy equipment and medical files gone astray in the maternity hospital. There were two cases in which the physician should have performed tubal ligation during the cesarean, since there was a risk to health, but the physician did not want to do it, according to the interviewees.

All of the 230 individuals who did not obtain surgery were asked whether they had been satisfied with the counseling that they received: 213 (92.6%) answered yes, while the remaining 17 (7.4%) said that they were dissatisfied because they thought that the counseling was unnecessary and was a very slow process.

When asked to indicate the positive and negative points of the counseling, 216 subjects gave an answer. Most of them (162; 75.0%) were satisfied with the counseling, while 54 (25.0%) made some criticisms.

Among the positive points, it was emphasized that the counseling enabled clarification of doubts regarding the surgery and about contraceptive methods; that this knowledge was necessary; and that they enjoyed the counseling. Among the negative points, they cited the delay in being called for surgery and the waiting time at the referral service, thus indicating that the attendance was not good. Several participants managed to present both negative and positive points, while the majority only presented positive points.

Two hundred and seven individuals were asked about how they made the decision to postpone the operation following counseling. Out of the 182 who answered this question, 127 (69.8%) said that they had made the decision themselves and, out of these, four (2.2%) said that they had been convinced, 27 (14.8%) said that they felt forced to give up the idea and 24 (13.2%) said that they had decided to give up the idea or postpone the operation for "other reasons", among which fear, lack of time or health problems. When asked if they had received the form for making the appointment for the surgery, 159 (69.1%) said that they had received it, while 71 (30.9%) had not. Around one third (80; 35%) told the professional doing the counseling that they had given up the idea of undergoing the procedure.

When asked whether they still intended to undergo the operation, 147 (64%) said that they wanted to do so in the near future and 23 (10%) in the more distant future. Forty-five individuals (19.5%) said that they did not think it was necessary any more, while 25 (10.5%) had already undergone surgery in another place.

Comparison between the individuals who apparently gave up the idea (n= 147) and those who did not obtain the procedure (n= 60) did not show any associations in relation to schooling, marital status, socioeconomic condition, income or religion. However, there were associations in relation to sex, age and color/race. A greater percentage of women did not obtain the procedure for reasons outside of their control, along with younger individuals and those with self-reported black skin color (Table 2).

 

 

In the multiple logistic regression, the only significant factor was color/race. Being black produced a risk of impediments relating to obtaining surgery that was 2.2 times greater (95% CI: 1.2;4.2).

Comparing the 230 individuals who did not obtain surgery and the sample of 297 individuals who underwent surgery, there were significant differences in relation to the variables of sex, age, religion, per capita income, marital status and schooling (Table 3). The variable of skin color was not included because it did not appear in the medical files.

 

 

Among the individuals who did not obtain the procedure, 78.7% were women. In the group of greater age (more than 39 years), there were more individuals who had not obtained the operation (22.2%) than who had (12.5%). Evangelical religion, higher per capita income and being single were associated with not obtaining the procedure. Greater schooling level made it more likely that the surgical procedure would be chosen.

 

DISCUSSION

Most of the candidates for surgical sterilization through SUS are characterized as married, white, Catholic, low schooling and income levels and belonging to social categories C or D.

The results from the present study confirm that women are younger than men when they seek surgical sterilization, as has already been mentioned in a previous study.8 With regard to religion, contrary to what the Catholic church preaches, sterilization is not a method that is little sought among the church's followers.e This could be related to the fact that surgery is a unique event in life and is preferable to continuous use of contraceptives.

Less than 15% of the candidates did not obtain surgery over the study period. The principal two reasons for not undergoing sterilization that were identified were: giving up the idea, which a majority of the interviewees indicated (and which for many of them meant postponing the procedure); and the barriers of the healthcare system itself, which impeded access. Postponement of the procedure might suggest good-quality counseling. On the other hand, almost one fifth of the candidates (18%) said that fear was an impediment to surgery.

Less than one third of the individuals who did not obtain surgery mentioned problems outside of their control. Among such problems were impediments coming from the spouse: these were considered to be gender problems when the man did not agree to sign the woman's form requesting sterilization from the health services. Other barriers related to the healthcare system and, among these, the long waiting time was the most important problem. This probably made 10% give up waiting and seek another health center. In the sample of 297 individuals who obtained the procedure, the mean waiting time was around eight months.f The long waiting time had already been mentioned as a factor denoting low quality of the service by other authors.1,7

The three home visits on weekdays and at weekends made it possible to locate almost 60% of the candidates who had not obtained the procedure. However, this is one of the limits of the present study that needs to be taken into account. The individuals selected may have been those who were in a better socioeconomic situation with greater stability of employment. Furthermore, the difficulties in locating SUS users in Ribeirão Preto may have related to the local labor market, which is cyclical because of the agricultural harvest seasons. Several studies have presented this cyclical characteristic of the population.4,5 On the other hand, the refusal rate was low (2.3%).

The individuals who suffered impediments most often were young people, women and blacks. In multivariate analysis, race/color was the main impediment. This is in agreement with a study on health service use conducted within the National Household Sampling Survey (Pesquisa Nacional por Amostra de Domicílios, PNAD, 2003) in which 4% of the Brazilians who did not obtain access to SUS were adults with black or mixed skin color, and with low schooling and income levels.6

Regarding the inequalities that affect health, Krieger (2005)3 indicated institutional discrimination as one of the several forms of racial discrimination that could be revealed through poorer healthcare for certain groups. In this respect, the Ministry of Health's ordinance No. 719 is opportune and necessary.g This has made it obligatory to include the question of color in all outpatient and hospital information systems, thereby enabling healthcare evaluations and actions towards diminishing the inequalities experienced by blacks.
