External causes of morbidity/mortality have been a serious public health concern in Brazil. The present study sought to explore Community Health Workers (CHWs) strategies and to understand how they manage this morbidity at the primary care level. There were studied 36 CHWs working in 7 different primary care services such as the Family Health Program in an area of the city of Porto Alegre, southern Brazil. The most prevalent external causes were accidents, including common accidents such as falls among the elderly and accidents among children. These events are not always recognized as preventable health problems and they are usually regarded as "unforeseeable events". According to CHWs, these events can be easily approached in the family since they are positively influenced by education strategies. We found that violence in its different forms is the most difficult event to be approached in the families as they involve risk situations. CHWs regard themselves unprepared to manage these situations, and emphasize referral problems by support networks in the area studied and in the city in general.
Keywords: External causes; Community Health Agents.
External causes are defined in the International Classification of Diseases - ICD 10 (World Health Organization, 1996) as health conditions causing morbidity or mortality and can be categorized into intentional and non-intentional/accidental events and events of undetermined intent as well. In the present study the classification of external causes also include "traffic accidents and violence, homicides, suicides, work-related violence and accidents in general" (Souza and Minayo, 1999).
Morbidity studies focusing on conditions that generate demands on (public) primary care services are rare. The studies in the literature are predominantly supported by mortality and hospital morbidity data. In the present study mortality data was used only as an illustrative scenario of the severity of events culminating in death. It was sought to call attention to underreporting and the poor quality of primary care records because these events are often made invisible or even naturalized, as in violence cases, hindering health promotion and prevention actions as part of planning of public health services.
External causes have ranked as the second leading cause of death in Brazil (Brazil, 2001) since the 1980s. They have accounted for 15% of all deaths reported, only behind cardiovascular diseases. Data from the National Health Council (Brazil, 2002) show there are 120,000 deaths in Brazil every year, which is comparable to the total number of deaths in historical conflicts such as the Vietnam and Gulf wars. Every year there are 630,000 hospital admissions at an annual cost of no less than R$ 351 million to the Brazilian National Health System (SUS). Hospital stay ranges from five to eight days, which indicates the severity of injuries.
Deaths are largely due to traffic accidents and homicides and they are the leading causes of death in those aged 5 to 45 years (Médici, 1992; Minayo and Souza, 1993; Chesnais, 1999; Souza and Minayo, 1999; Sant'anna, 2000; Leal, 2003; Gawryszewski et al., 2004). These events impose a major social burden due to lost lives and their sequelae, and entail a financial burden due to their direct and indirect costs.
In the State of Rio Grande do Sul, southern Brazil, external causes is the fourth-ranking cause of death, behind cardiovascular diseases, cancer, and respiratory diseases (Sant'anna, 2000). A similar scenario is seen in the city of Porto Alegre. There were a total of 890 deaths due to external causes in 2003, of which 718 were among males and 172 among females. Male deaths predominantly occurred among those aged 20 to 29 years, of which 248 were due to external causes (Porto Alegre, 2003).
This epidemiological reality allied to underreporting of morbidity due to external causes characterizes a situation that is likely to be even more serious. Poorly recorded information and the very difficulty of identifying these events in primary care settings make this reality invisible at the local level hindering control and prevention strategies and interventions.
Studies involving health providers and services can produce information on local morbidity and mortality and provide input for the development of geographically focused health promotion and prevention programs. It is thus sought through a diagnostic research approach components that may help elucidate this reality and contribute to develop health system and community actions (Gonnet, 1992 in: Lopes et al., 2004). The purpose of the present study was to describe these events, their place of occurrence, and people injured and to provide information to help planning local actions supported by the care system.
The Observatory of External Causes was established for the surveillance of these events in the health administrative areas of Lomba do Pinheiro/Partenon in the city of Porto Alegre. One of the Observatory's roles is to collect information and maintain a database to support local studies and care delivery.
The present study, supported by the Observatory, investigated morbidity due to external causes focusing on Community Health Workers (CHWs) actions. CHWs are the cornerstone of strategies for identifying and following up these conditions at the primary care level in the area studied.
The CHW is a member of the Family Health Program team and a link between people's health needs and what can be done to improve their life conditions; they are a bridge between people and health providers and services (Silva and Dalmaso, 2002; Ferraz and Aerts, 2005). CHWs do not have specific health training, and they are incorporated into the health team because of their link to the community served. Their work involves enrolling families; home visits; active search of no-shows; assistance in demands for program actions; education activities, outreach and other support activities at health units. They have a considerable potential in action dynamics and implementation in the services. For that reason there is a need to further explore how CHWs think and how they manage the different situations they are faced with, which could provide input for improving record and care quality. The objective of the present study was to explore and better understand how CHWs develop intervention strategies for managing morbidity due to external causes. A qualitative study was conducted based on the following guiding questions: how do CHWs define external causes of morbidity? Do they perceive the different dimensions of the external causes as a health issue in the community? Do they systematically develop intervention strategies together with families? How are these strategies implemented in their daily practice? Are home visits an instrument of these strategies? How are they conducted? Are there any action plans devised based on this issue and their proximity to the community?
The study was based on information obtained from a database comprising records of 14 primary care services in the areas of Lomba do Pinheiro and Partenon in the city of Porto Alegre. This area comprises nearly 180,000 inhabitants living in poor socioeconomic conditions. As a local test, a group of reporting agents of external causes of morbidity was created including care team members. These observers-reporters became sensitized to the study issue through weekly meetings and group dynamics with case studies provided by a local multiprofessional team. A local reporting instrument was then created that was regularly discussed and improved during group meetings. This group currently comprises different health care providers and, most importantly, CHWs who have a key role for managing these conditions. Records from case reportings were systematized into a database by partner researchers at Universidade Federal do Rio Grande do Sul Nursing School (EENF/UFRGS) and provided a variety of data such as type of event, type of injury, body area injured, place of occurrence, perpetrators, referrals, case management, besides more subjective information with detailed account of events.
A qualitative approach was used to study morbidity due to external causes between June and December 2005. The study area included an emergency care unit, seven units providing the Family Care Program (FCP) and six basic health units serving a population of around 180,000 inhabitants. Data was colleted in the FCP as CHWs were part of care team in these services.
A qualitative study is justified by the need to go beyond data from care records in the study area. To explore management practices, discourse elements were analyzed to grasp behaviors for the management of conditions and especially for the management of different violence situations. Semi-structured interviews were used as a guide. A questionnaire was developed taking into consideration CHW ability: to identify the events and perceive them as health public issues (not only as criminal cases as in the event of violence); approach families and develop strategies for action; plan actions together with the care team and the community. CHWs were interviewed by the researchers and their interviews were scheduled during working hours after management authorization.
It was opted to interview CHWs from local area services to ensure a more comprehensive scenario of perceptions and management practices. Of a total of 44 CHWs, 36 were working in the study area. Eight of them were not interviewed as they were on sick leave during the study period. Result presentation included first demographic data and then information was categorized into three thematic content groups based on CHWs' view: morbidity due to external causes; management strategies of morbidity due to external causes; family approach and action effectiveness.
Demographic data are here presented to profile these individuals involved with health work. Most CHWs (30) were females and 6 were males. Fourteen of them were 21 to 30 years old and 22 were 21 to 40, accounting for 61.1% of all interviewees. In recent years younger people have been admitted to the Community Health Worker Program (CHWP) and FCP as they have better education and abilities and thus perform better in the job selection process (Ferraz and Aertz, 2005). As for schooling, two (2) CHWs had incomplete elementary education, two (2) had complete elementary education, seven (7) had incomplete high school education, twenty (20) had complete high school education, and five (5) had incomplete college education. It should be noted that those with higher schooling were also younger, which suggest a trend to hire agents with better education and abilities.
This profile is similar to that seen among health workers in general. CHW work engages more women, suggesting this is a gender-matched activity. Working close to families and having skills developed in the process of socialization of women are characteristics that support women's presence and a gender-oriented selection during the hiring process for this job. Higher schooling and younger age suggest a search for job opportunities in health that will entail potential development of other abilities. It was found that generational and gender-oriented cultural aspects act as facilitating and/or limiting factors in the management of complex situations such as violence.
Information from the Observatory of External Causes hosted at EENF/UFRGS was used as well as local records of conditions obtained from notes of care provided and reported household and community events. A community reporting is made when a CHW conducts a home visit or is approached by community members to report an event. They try to obtain information on the event and make the reporting. Analysis was performed through thematic contents (Minayo, 1996) of the three categories created from the guiding questions described before to help understanding how CHWs managed morbidity due to external causes as well as their management strategies and practices.
The regulations of Resolution No. 196, of October 10, 1996, for human studies were followed and the study was approved by the Research Ethics Committee of the Local Administration of the City of Porto Alegre. All participants signed an informed consent form and their confidentiality was assured by replacing their names with flower names.
Morbidity due to external causes according to CHW perception
To answer the question, "How do CHWs define external causes of morbidity?," Table 1 summarizes the different definitions found in the interviews, categorized as "accidents and violence," "accidents" only, and "violence" only.
Based on definitions of external causes by ICD-10 and by Souza and Minayo (1999) as well CHW perceptions on the variety of these conditions were analyzed for their comprehensiveness in the interviewees' discourse.
Most interviewees (20) associated their answers directly or indirectly to violence and accidents, as seen in Tabebuia flower and Victoria amazonica discourses:
Anything that leads to a risk situation that is outside the body. I have often seen falls, physical violence, and injuries due to sharp objects. I've seen a lot of sexual and psychological violence but you find it hard to approach them because the person has to talk, it is something visible, we only realize it on a daily contact when you see they are not ok. (Tabebuia flower)
They are all other causes rather than disease: a fall, a cut, domestic violence. On a daily basis, there are often seen accidents with children, dog bites, and intrafamily violence. (Victoria amazonica)
Ten (10) CHWs believed health conditions due to external causes were associated to accidents only, and they did not give any relevance to violence or did not mention it at all. This may be because these interviewees were in charge of areas where street violence is less widespread; or either because they were not able to perceive the different forms of violence such as health conditions, "naturalizing" violence which is common to that.
Of all participants, six (6) said health conditions would be associated to violence without mentioning accidents. This perception indicates that a significant number of CHWs still did not fully recognize these events, probably because they did not have resources or a "sensitive eye" to identify them as preventable health issues. Accidents are commonly regarded as "unforeseeable events". It is verified the association of violence as a health issue; however, some CHWs did not perceive its different dimensions, and the variety and complexity of these events. Violence is not easily recognized as a health or "non-health" issue and it is even more difficult to manage it.
When CHWs were asked about the most common external causes they found in their work, most referred to more than one subtype. Many said they had contact with all the events as summarized in Table 2.
Overall accidents, falls, and accidents with children had 37 citations. Falls were most frequently seen among the elderly; burns, domestic accidents, and animal (dog) bites were more common among children.
Studies on hospital admissions show that burns are frequently seen in children under 5. They have high risk for morbidity and death due to these causes (Brazil, 2002). Admissions due to falls are also remarkable among the elderly.
Physical violence due to gang fighting involving drugs, sharp objects, and firearms was referred thirteen (13) times in the interviews. In fact many studies show firearms as the main cause of deaths and sequelae.
Intrafamily violence was referred ten (10) times in the interviews, psychological violence three (3), and sexual violence four (4). This categorization into subtypes of violence was based on interviewees' discourses as shown in Table 2.
While some CHWs were sensitized to this issue, others had little information or even no information at all. Ill-definitions and specific inability may make it more difficult to identify, record, manage these conditions.
CHW strategies for the management of morbidity due to external causes
CHWs play a central role in the management strategies for these conditions. Most strategies include assistance at home, in groups, streets, waiting room, school, and referrals to support services, in addition to the management of care teams and services involved.
In the present study it was found that CHW management strategies most often included assistance and referrals to the health unit. Fall prevention among the elderly and common domestic accidents in children were often addressed as can be seen in the discourse below:
I ask them to remove the many rugs on the floor, an extremely smooth floor is dangerous. We try to see what is wrong at home, from the garbage outside that can be a source of rats, the elderly who are not groomed and cannot provide their own self-care, it is violence. We talk about all that, we tell children not to get close to the stove, we talk about the pet children love, some can be wild and children may tease them and get hurt, and dogs have flees and may cause allergies. Rugs are the most basic aspect and this is a widespread problem, it is fatal. Everything you learned you have to repeat and repeat, even a glass splinter that needs to be collected from the yard. It sounds like a stupid thing but some people don't know it, they don't care (Palm).
CHW reports showed that some users did not either perceive or recognize these conditions as a problem. During a home visit, CHWs have the opportunity to observe housing conditions and can identify problems and provide basic assistance oriented to their reality (Ferraz and Aerts, 2005). For them, this basic assistance was not ready and required to be adjusted to people's reality.
Health groups CHWs create in the streets can provide people information about the prevailing condition in their area and its causes. According to the interviewees, "it is a way of preventing these conditions," as they believe the knowledge on the most common occurrences will make people able to take actions and help prevent them.
Another strategy was basic assistance in the waiting room of health services. CHWs took the opportunity to inform users waiting to be seen. In Education in Health groups developed at the FCP, for instance, patients with high blood pressure would tell about events taking place at people's home, or even reported them when they met CHWs on the streets.
As for referrals, CHWs reported they assisted victims with information about public services that could help them manage their cases such as Women Police Station, Elderly Advocacy Services, Tutelage Council, Viva Maria Support Center (a protected shelter for women victims of violence in the city of Porto Alegre) among others.
Actions were developed aiming at prevention and intervention for conditions that seemed relevant and had an impact on the community. Most agents reported positive results and that people would follow their advice. These "small rewards" seemed to have a strong encouraging effect and they continued to implement them, even thought they were isolated actions of low efficacy in general.
Family approach and action effectiveness according to CHWs: "learning how to win people's trust"
Most CHWs (22) reported their approaches were effective. Sometimes it takes long, it moves "at a snail's pace", but a result is achieved. CHWs seem to have a key role in the identification, prevention, and intervention of events supported by information, education, and increased awareness through home visits which are their first-choice strategy.
In regard to family approach, CHWs said they had to be "tactful," and "learn how to win people's trust" so they would feel confident to report what was actually happening and what factors were involved in each situation/event.
Depending on the event, we have to approach them discreetly, go step by step to get to know what actually happened. Some people don't even want to mention it. So I get to their homes, I ask what happened, how it happened, if there was an argument. You have to be tactful to approach each family. (Violet)
Most CHWs took a direct approach to the family, they did not "beat around the bushes," and they showed them the consequences of certain behaviors. However, when dealing events related to drug trafficking, they did not address them directly, they started by exploring "the edges" to give people time to open up and report the event.
I'm direct with the family. I seldom beat around the bush. I just don't talk openly about drug trafficking; in these cases, we have to win them bit by bit. But I usually tell them the consequences of their behavior. When children are involved the family has to care about them; when dealing with parents sometimes I call them names. (Tabebuia flower)
CHWs reported their approach was easier in the event of accidents while it was harder when dealing with violence or crime cases such as drug trafficking. In the event of accidents, people were given assistance and a reduction of occurrences could be seen. But while dealing with violence events, management involved not only CHW and FCP team actions but also competent authority action since, as CHWs said, "there is no use in referring people to services if competent authorities are irresponsive".
"Better not see!": violence management
Violence is also found within families as it includes other forms of violence rather than killing. Health providers have a key role in the management of intrafamily violence (Minayo, 2004).
Hence, approaches to violence events were distinct from all others because CHWs did not directly address families in these cases. They collected information bit by bit. There were instances where victims sought care at FCP and a violence case was suspected. CHWs would investigate the event by talking to the victim's neighbors and friends to know what happened.
Most CHWs, as seen in Jasmine's discourse below, reported they "pretended they did not see," as they were afraid violence would be turned against them. Jasmine said CHWs should be "ethical," they should set boundaries to gain access to families so they will be respected by "trafficking agents," "the drug lords of the area".
People are afraid, sometimes the shooting starts on Thursday and goes on over the weekend. They respect you, you have to set boundaries to have access. If I want to go around the neighborhood at night, they respect you. I see a lot of things and pretend not to see them, you have to be ethical and let them go by because you also live in the neighborhood, and you work at the health unit. (Jasmine)
This situation made it difficult to identify, assist, and report violence cases because CHWs and team members who had a closer contact to people also lived in the same "neighborhood". At the same time, they were the ones more familiar with violence cases and could potentially report them. Direct contact with the victims allowed to more easily identifying them. But Tulip said that because she lived in the neighborhood they felt intimidated to take the right action, i.e., refer cases to the competent authorities:
There are many cases in my area related to external causes. As I live there, you assist people, you try to help them but you cannot go deep inside, you cannot get fully involved in the event of rape, violence. I think we cannot get too involved in our work, you have your family, and you have kids. When it is a parent with a child [sexual violence] you try to gather information, you give them advice regarding drugs but you don't try to go deep inside.
Some CHWs did not report cases out of fear because some victim's families were very violent. The Tutelage Council does not assure confidentiality of the reporting person, which prevents reporting in many cases. A female CHW, for instance, did not regard violence as a family health issue, and reported she addressed only health-related issues but not violence cases. It evidences that, to many CHWs and service users, these events have become "naturalized," or are just "police cases". Violence situations can generate more violence; and negligence resulting from fear is also a form of violence. However, some CHWs did not consider this behavior negligence. One cannot criticize their attitudes because these workers often did not have any support and felt intimidated to report these cases. Besides, they also feared something could happen to their own families. These situations can be identified in the discourse below:
I work with health, I check the family's health. In the event of a rape, it eventually bursts out but it's not me who takes action, my approach is health-related. Yeah right, I get there and tell him he's been abusing his daughter for seven years. I would never be able to go back to that neighborhood. Deep inside I would like to take a stand. I assist the injured people and give advice about drugs. I don't believe in the Council, they let things get serious and do nothing. I get outraged by some things. These things make you sad because instead of protecting and helping you, they do the opposite. I don't see much result from our work. The Council does nothing, they are funded but do nothing. You try to do your share but it doesn't work out with the others. Everything is connected (Tulip).
One of the challenges facing health providers is to perceive and report intrafamily violence. It is estimated that only 2% of sexual child abuse within families and 6% outside the family, and about 5% to 8% of sexual abuse in adults are reported in Brazil (Brazil, 2001).
CHWs and work ability: how can they be prepared to deal with "what lies behind a door"?
With respect to CHW ability to manage these events, most (15) said they were prepared to deal with them while eleven (11) said they were not.
Some, like Rose, considered themselves prepared to manage external causes, while others said this preparation "means nothing": despite all assistance people get no response and it is really disheartening. The solution, according to Rose, is to develop a good relationship with those people who really "work out," which can encourage CHWs to keep doing their work. Poppy also said that "despite all capacity building, they will never be prepared because each case is a different case, and even if they prepare themselves for a home visit, the reality found is completely different and you never know what lies behind a door".
Among those who said they were not prepared to deal with these situations, the majority mentioned the need for improved capacity building. Bourgogne said she felt intimidated by some families, and they needed to learn how to approach them focusing on the issue of violence. Chrysanthemum mentioned the same reason for feeling intimidated, and she said they did not feel confident to take the right actions.
As for facilitating factors and difficulties of their work, most CHWs (7) said "they were welcome by people and families". Seven (7) CHWs also mentioned they had easy approach to families in the event of accidents such as falls. But most (8) reported difficulties dealing with violence cases.
Violet said she had difficulty dealing with drug trafficking. People showed resistance to their approach in these cases so "sometimes you'd better not see". The same difficulty was reported by Jasmine and Sunflower. In the event of accidents such as falls, the approach was easier. Seven (7) CHWs also reported having problems with the response by competent authorities, their involvement and response actions supported by the team.
These CHWs reported the management of violence cases was further compromised because the support system did not work as it should. As Palm reports below, cases were reported but the team did not get any follow up on them or about actions taken by competent authorities.
The difficulty is to deal with violence, with the system, it doesn't work out as it should. You visit a home, a school, come to the health unit, you report it to the Tutelage Council. You get emotionally involved in cases of violence involving children and elderly people. Sometimes you do not know what happened and people open up and tell you what happened, they detail the situation, you have it in your hands and do your share but you get no follow up on the case because the authorities do not give you any response, some cases even remain open. (Palm)
Petunia and her colleagues reported no difficulty approaching families. Even the most violent families would welcome her because she had a very good relationship with everybody. But the difficulty lied in not getting any response, cases were passed on and they did not give them the required attention, which was really frustrating.
A facilitating factor is that I have a very good relationship with them. In my area of work most have fixed residence, I know everyone and I know how to approach them despite they being violent. Also they welcome me and I try to take their stand, to communicate with them in their own language. I try to be well-informed about the services available, and I enjoy creating groups for people to get to know each other. I have difficulty with the response, I give a lot of support to all the people I work with but when the cases are brought to the team, they don't go there and visit them at their homes to know them, they consider it a minor issue, and this response is frustrating. (Petunia)
Lack of response from competent authorities was the most referred difficulty along with ineffective management of cases and case reportings, and inaction from authorities that sometimes "not even go to the place of reporting to investigate". These were the most serious problems. These issues seem basically associated to the limits imposed to people and families resulting from difficult access to goods and services and to better quality of life.
CHWs directly and indirectly defined external causes as violence and accidents. Some focused their answers either on accidents or violence. These findings show that a significant number of CHWs do not perceive or understand the different dimensions of morbidity due to external causes in the community. They do not have the required resources to identify these causes and therefore are not prepared to manage them. It is believed that these situations and difficulties lead to underreporting of morbidity due to these events since CHWs provide a link to primary care and are the representatives of public authorities in direct contact with potential victims.
Misinformation and little or no training make it difficult to work with people and families. Effective surveillance and actions would require capacity building to improve knowledge and abilities to identify and manage these events.
Most interviewees systematically developed intervention strategies for families as they provided assistance during home visits and consultations at health units on how to prevent and manage conditions. They also managed the most common external causes in their area of work through street groups, talks in waiting rooms, among others. It was found they have a key role in education, raising awareness, and involvement of people for problem management. The actions developed aiming at giving visibility, and promoting prevention and changes of morbidity causes seem to produce a major impact locally as CHWs believed their work had a positive result and their approaches were effective.
Strategies are usually employed during home visits. Approaches are gradually implemented and can produce results only when CHWs are able to win a family's trust. Their work during home visits is a first-choice instrument to tackle this issue.
The present study evidenced that external cause events or conditions call for the involvement of all health team providers and especially CHWs as they are key for approaching families and identifying risk situations. It was found that health teams were generally not closely involved and provided little support for case reportings and referrals required in different situations. Isolated actions tend to be ineffective and to discourage those engaged in "hand-to-hand" work. Frequent sick leaves (as seen by the number of CHWs on sick leave at the time of the study) and sometimes absenteeism may indicate defense and protection mechanisms to cope with suffering workers face in work situations. Another aspect is the need for community and intersectoral support to create a network of attention and care services. Building capacity allied to all these components mentioned before is crucial because to identify these conditions one has to have a "sensitive eye," which is able to denaturalize situations, provide input, and encourage people to manage them.
