ABSTRACT

Objective: To identify tuberculosis-related health care and surveillance actions in Prison Health Units. Method: Cross-sectional study, of quantitative, exploratory and descriptive character. We visited 13 Teams of Prison Health, and nurses and technicians were interviewed regarding epidemiological surveillance instruments, physical structure and materials. Results: Search for respiratory symptoms in admission was reported by 6 (46.2%) of the teams, and the smear microscopy was the most requested test. The Logbook of Respiratory Symptoms and the Logbook for Monitoring Tuberculosis Cases were used in 7 (53.8%) institutions. Two of them (15.4%) had a location for sputum collection and 1 (7.7%) had a radiographer. The Directly Observed Therapy was reported in 7 (53.8%) units. Conclusion: Health care actions related to the search for respiratory symptoms and Directly Observed Therapy should be expanded, as well as surveillance actions and recording in official documents of the National Tuberculosis Control Program.

INTRODUCTION

The World Health Organization (WHO) estimates that 10.4 million people contracted tuberculosis (TB) in 2016, leading to 1.3 million deaths among HIV seronegative patients and 374 among seropositive ones, thus being characterized as one of the leading causes of death in the world(1). The weakening of the immune system, caused by the co-infection with the Human Immunodeficiency Virus (HIV), promotes its development. Social factors as unhealthy living conditions, malnutrition, and low income lead to greater vulnerability to the disease®. Lack of bonds and support, prejudice on the part of professionals, and difficult access to examinations, consultations and treatments are bottlenecks on the control of TB in primary health care(3).

Among the vulnerable groups, one may highlight the indigenous peoples, street populations, and people deprived of their liberty (PPL). Health professionals also have a higher risk of TB infection and development®. Brazil has the fourth-largest prison population in the world, in which the TB incidence is 28 times higher than in the general public, and the lack of disease management becomes a risk factor for the community®. TB is a persistent disease in prison systems, mainly due to the late diagnosis, high prevalence of antimicrobial-resistant bacteria, improper treatment, use of illicit drugs, overcrowding of prison systems, poor infrastructure conditions, high prisoner turnover and low socioeconomic poweh6®. The TB is a second penalty for the detainees and the high risk of developing the disease is shared with security and health professionals, visitors, and the general public®1'®.

Screening TB in prisons is a challenge; hence, early diagnosis and proper treatment must be prioritized(11). The PPL with active TB must be monitored through the health network, thus minimizing the chances of treatment interruption and recurrence. The development of policies, programs and strategies, such as the search of respiratory symptoms (BSR), contacts' examination, culture, susceptibility testing, co-infection diagnosis, directly observed therapy (DOT) and educational actions are essential to achieve the goals of "The Global Plan to Stop TB 2016-2020" to eradicate the disease until 2030®601'®.

The Ministry of Health (MS) established in 2003 the National Health Plan for the Prison System (PNSSP), to ensure access to health for the convicts, offering primary health care services within prison units(13). In 2014, the National Policy of Integral Attention to Health for People Deprived of their Liberty in the Prison System (PNAISP) extended the health care to all people deprived of their freedom, including provisional prisoners; however, technical and bureaucratic barriers still persist, and so do prejudice and discrimination0^.

The PNAISP advocates the comprehensiveness of health care in the prison systems, as well as multi-professional teams consisting of doctor, nurse, dentist, social worker, psychologist, nursing assistant, and dental office assistant. Each team should be responsible for 100 to 500 prisoners, and in units with less than 100 detainees the health care is the responsibility of the Basic Health Unit in the territory03'®.

Municipalities that adhere to the PNAISP receive financial incentives to perform health care within the prison system; however, this system lacks monitoring and evaluation on the actions taken.

OBJECTIVE

To identify tuberculosis-related health care and surveillance actions developed in Prison Health Units of Rio Grande do Sul.

METHOD

Ethical aspects

The study was approved by the School of Penitentiary Service of the Superintendence of Prison Services (SUSEPE) and subsequently submitted for evaluation and approval of the Research Ethics Committee of the University of Santa Cruz do Sul (CAEE 48170715.0.0000.5343). In this study, the Informed Consent Form (ICF) was used and all participants had their identity preserved and guaranteed at all times.

Study design, location, and period

This is a cross-sectional study, of quantitative, exploratory and descriptive character, conducted in Prison Health Units of Rio Grande do Sul from August to October 2015.

Population and sample: inclusion and exclusion criteria

At the time of study, the RS featured 18 prison health units, distributed into 15 municipalities, and five (38.4%) of those units have more than one health team. Units that bear only female prison population, units difficult to access, and those in which the professional contacted was not found at the time of the visit were excluded from the study. Thus, 13 (72.2%) prison health units were part of the study, being 4 (30.8%) of them located in the city of Charqueadas (Figure 1).

Study protocol

Visits were scheduled in advance, through a prior telephone contact with the unit's nurse. Two instruments were used for data collection: a questionnaire addressing general data on the penitentiary and its health unit, human resources, and health care; and a check-list type instrument, structured based on the document prepared by the Operational Study Group on TB of the University of São Paulo (USP). This, in turn, was referenced on the Primary Care - Assessment Tool (PCAT), proposed and validated in Portuguese for the Primary Health Care (PHC), aimed at identifying epidemiological surveillance instruments, physical structure and materials(15). The Logbook of Respiratory Symptoms (LRSR) and the Logbook for Monitoring TB Patients and Cases Treatment were instruments also evaluated. Professionals interviewed were nurses or nursing technicians, as they are responsible for managing the prison health teams.

Analysis of the results and statistics

Data tabulation was performed in an electronic database in Microsoft® Excel 2010 (Windows 2010 Operating System, Microsoft Corporation Inc.). Descriptive and univariate analyses were carried out using the software Statistical Package for the Social Sciences (v. 20.0). Values were expressed as mean and standard deviation or absolute numbers and percentages.

RESULTS

The prison health teams of this study are composed of health professionals from the municipality and the Superintendence of Prison Services (Susepe). Twelve (92.3%) of the prison health units had a minimal health team, consisting of a doctor, nurse, dentist, social worker, psychologist, nursing technician and dental office assistant. Professionals such as a physical therapist, occupational therapist, psychiatrist and bio-medic were present in 1 (7.7%) health unit. The number of professionals ranged from 6 to 34, as some of the units visited had more than one health team. Nursing professionals and social workers have a higher weekly workload compared with the other professionals.

The study was conducted with 10 (79.6%) nurses and 3 (23.1%) nursing technicians of the health teams. All prison units studied were male prisons of closed or semi-opened regime; 10 (76.9%) were overcrowded (Table 1), and their demographic composition was predominantly young men, with low education and socioeconomic levels.

It was not possible to evaluate whether penal institutions with higher occupancy rates also presented a higher TB prevalence, as the Penal Institution No. 12, which had the second highest occupancy rate, did nor report on the number of TB cases at the time of the study.

In the units visited, the spontaneous demand was identified as the most common form of TB detection. The most frequent diagnostic methods in prison units were the smear microscopy, sputum culture, and chest x-ray. The Rapid Molecular Detection for Tuberculosis (RMD-TB) was found in one (7.7%) prison located in the State capital (Table 2).

The BSR at the admission to the prison system was reported by 7 (53.8%) teams, and 6 (46.2%) teams performed screening up to 6 days after admission; whereas one of them (7.7%) did not use time standardization for screening on admission.

As for the DOT, in 7 (53.8%) of the units it was conducted will all patients and in 2 (15.4%) it was performed only when there was no adherence to treatment; 4 (30.8%) units reported using the monitoring file of daily intake of medication. In most units, the DOT was conducted by the nursing professional.

Regarding interventions in the TB transmission chain, one can see that 3 (23.1%) units chose to isolate ill prisoners, and all of them state the summons for diagnosing the contacts are paramount; contacts inside the walls of the prison are evaluated at the own unit and contacts outside are forwarded to the municipal reference. Guidance to visitors of positive cases were carried out by the health team professional in 4 (30.8%) units.

In one (7.7%) unit, the LRSR had been replaced by an own tool of monitoring, one (7.7%) interviewee did not know what the book was about, and 4 (30.8%) did not use it. On the other hand, it became evident throughout the check-list that the Logbook for Monitoring TB Cases Treatment was replaced by own instruments in 3 (23.1%) units, one (7.7%) interviewee did not know what to answer and 2 (15.4%) did not use this instrument. The compulsory disease notification was evidenced in all units, as well as the existence of medical records of the detainees. The monitoring file of the daily intake of medications was not used in 9 (69.2%) of the units visited (Table 3).

As to the existence of a specific location for sputum collection, 11 ·84.6%) of the units visited did not have this structure and 4 (30.8%) had no refrigerator for storing biological material. Regarding the transport of biological material, one (7.7%) unit did not had Styrofoam boxes for transporting samples to the laboratory (Table 4)

DISCUSSION

The interviews held show the insufficient implementation of the TB Program in prisons, where the recommendations of the Ministry of Health are partially followed by the prison health teams. TB diagnostic exams require better implementation, especially in the performance of sputum culture for all suspected TB, BSR strategy at admission to the prison system, and DOT for all cases diagnosed.

Overcrowding and unsanitary confinement conditions are factors that contribute to the maintenance of the TB transmission chain within the prison system. Agglomeration and poor dwelling conditions were also factors evidenced in other Brazilian prisons, which came to contribute to the PPL illness, becoming an obstacle in the fight against TB(16). Prison systems are a high-risk environment for the transmission of TB between contacts and communities outside the walls. In Brazil, 25% of the TB cases occur among prisoners, who represent less than 1% of the population. In Mato Grosso do Sul, people who had been arrested had 23% more TB cases than the general population™.

Strategies adopted for TB control in prisons remain essentially biomedical (case identification and treatment) and educational, and have a limited effectiveness if not associated with measures for improving environmental conditions, seldom implemented08™. The functional dynamics of penal institutions difficult the integration of health routines, and may limit the actions to control TB and other diseases™. Scarce and inefficient health services are a source of great dissatisfaction among the prisoners™.

The TB identification form through spontaneous demand occurs when the prisoners voluntarily seek medical care with acute symptoms of the disease(16). Communication deficiency between health and security teams, the high turnover of prisoners, and the large number of admissions are factors regarded by the professionals as weaknesses in screening the disease. The National Program of Tuberculosis Control (PNCT) recommends that new TB cases are detected through spontaneous demand, questioning on cough in the entryway of the penitentiary system, annual systematic active search, treatment supervision, and information/ awareness of PPL and prison security teams(22). Another Brazilian penitentiary performs the BSR in up to 7 days after admission, and the exams most frequently requested are the smear microscopy, sputum culture, and antimicrobial susceptibility testing (SRT), in addition to the offer of HIV serology(16). Decentralization at the prisoners' entrance in the prison system was a harmful factor in realizing the BSR.

The RMD-TB test is still seldom present in penitentiaries of Rio Grande do Sul (RS). The RMD-TB sensitivity is about 90% (whereas the smear microscopy is 65%), the specificity is 99%, and the result is released is just two hours, favoring the timely start of the treatment. In addition, the RMD-TB also detects resistance to rifampicin, one of the main drugs used in TB treatment, making it possible to identify cases of resistance to the basic scheme, reducing the time required for starting the treatment with second-line drugs(23). Triage performed by radiological exams allows for greater TB detection when compared to the detection through clinical symptoms, but is little used in the prison system(24).

The DOT is not developed in its fullness by the prison health units studied, despite the PPL belong to the risk group of treatment discontinuation. The DOT aims at contributing to the greater adherence to treatment and consists in the observation of TB medicines intake, preferably every day, by health professionals. Such strategies allow for a higher probability of healing and less risk of bacterial resistance, establishing links between patient and professional™. In Colombia, the DOT implementation has significantly contributed to TB healing when compared with the period in which it was not performed in the units researched. When analyzing determining factors for treatment abandonment, most cases are related to how the health services are organized to develop disease control strategies. Reasons related to treatment abandonment can be solved with continuing education actions, active search of cases, and strengthening of the strategy of daily observation of medication intake(25).

Isolation is a factor much discussed among health professionals. Most teams do not isolate TB patients, following the MS guidelines. There is no need for isolation for those patients already inserted into the prison system because the inmates have already been widely exposed to infection risks and the infectiousness tents to decrease rapidly after the onset of treatment™. In Bangladesh, it was evidenced that the BSR, immediate isolation, and treatment of people with pulmonary TB resulted in a decreased transmission within prisons(26). In Espírito Santo, the detainee is forwarded to respiratory isolation in a specific cell from the suspicion of disease, until it is confirmed or not through laboratory exams(27).

The control of contacts is an important tool to prevent illness and to diagnose early active cases of disease, and must be established by TB control programs. Such coexistence environment can be the home, work environments, long-stay institutions, and prison units(28). The guidance to external contacts, such as family and visitors, is not directly addressed by health professionals for the most part, and the prisoner itself must guide them(18). In several units, the ill convict was responsible for guiding their own visitors. A study conducted in Ribeirão Preto/SP showed the knowledge of families on TB was unsatisfactory since they knew the predisposing factors to illness, transmission forms, and disease symptoms, but some associated the disease transmission to the sharing of clothing and cutlery, contaminated food, and sexual intercourse, which can lead to patients' discrimination and social exclusion™. Thus, continuing education and awareness of the entire prison population, including family members and professionals, on the importance of early diagnosis and adherence to treatment would be of paramount importance™.

Logbooks are used for epidemiological monitoring of the disease within the population, but few teams used them. Data on the investigation, diagnosis, and monitoring of TB cases are recorded in various collection tools that are used for evaluating control actions at a local level, according to PNCT recommendations. The LSRS and the Logbook for Monitoring TB Cases Treatment are some of the data collection instruments routinely used by health units™.

The Logbook for Monitoring TB Cases Treatment is an official information tool of the PNCT and should be used for the basis of calculation for operational and epidemiological indicators. Data provided by the book shall feed the TB Notification/Investigation file and the Bulletin of TB Cases Monitoring, both of the Information System for Notifiable Diseases (SINAN)(31-32). The SINAN subsidizes prevention and control actions for diseases whose notification is mandatory, and must be fed with trusted data. Among the diseases that require a database to support the prevention and control actions, the TB should be highlighted due to its magnitude and prevalence™. In 2007, the MS introduces in the SINAN file the information on the prison source, which contributed to a better understanding on the disease information in the prison system(32).

Regarding the existence of a location for sputum collection, teams reported that collection occur in the bathroom, cell, gallery, the own infirmary, or in a well-ventilated spot. A study on Primary Health Care (PHS) services, conducted in the countryside of São Paulo, verified that none of the units had a suitable location for sputum collection™. In 2003, the PNSSP established that prison health units should have a collection room with natural ventilation, refrigerator for storing the biological material collected for laboratory tests and thermal boxes for sending samples to the reference laboratory™.

Despite specific legislation determining the same minimum workload for all professionals of prison health teams, namely: 6 weekly hours for each professional of the type I Prison Primary Health Care Team (EABP), 20 weekly hours for type II EABP, and 30 hours a week for type III EABP; in practice, nursing professionals and social workers are present most of the time in prison health teams(35).

Study limitations

This study was limited to evaluating tuberculosis health care and surveillance actions in penal institutions and has not evaluated HIV data and co-infection. Actions of training, continuing education, information, and awareness of PPL and health and security professionals are still incipient. It should be noted that interviews were carried out with one member of each health team, not representing the entirety of professionals of Prison Primary Health Care teams. Furthermore, they represent the picture of a particular time, which can be modified by the replacement of some professional of changes in the work process. Thus, the continuous monitoring and evaluation of surveillance and care actions developed by prison health teams is recommended.

Contributions to the field of Nursing and Public Health

This study contributed to a diagnosis related to tuberculosis health care and surveillance actions in penal institutions with Prison Primary Health Care teams in Rio Grande do Sul. Tuberculosis control in penitentiaries can have repercussions in decreasing the incidence of cases in the community. In the field of Nursing, research involving health surveillance are of paramount importance, considering that in the course of academic education the nurse is prepared to act in epidemiological research. This professional is on the front lines of health care, in direct contact with used and the multidisciplinary team, actively participating in the health-disease process of the population. Recognizing such scenario of TB in Prison Health Units, the nurse can act in conducing public health actions, which acquires significant importance in implementing disease control activities.

CONCLUSION

Regarding health care actions, the spontaneous demand is the main means of care, the isolation of confirmed cases is applied by some health teams, there is a lack of materials and equipment, and the DOT is seldom used. As to epidemiological surveillance actions, the positive points are related to the laboratory and radiological confirmation of suspected cases, the SINAN notification, registry in the patient records, and evaluation of contacts. The BSR, guidance to family members, and use of specific registration tools should be extended by prison health units. The BSR is an activity that requires planning, strategies and support of the prison security team. Destruction of logbooks and limited registration on them reflects on the health care and, consequently, on the prognosis of the ill prisoner. One can also question whether the absence and reduced number of TB cases in some of the units visited may be related to failures in information records. The registry is extremely important because they underlie indicators and favor the development of action plans. Nurses are responsible for contributing to the development and TB health care and surveillance actions, improving conducts relating to records held in the units and increasing the identification of respiratory symptoms and cases diagnosed.
