SUMMARY
Objective: To
describe the design, validation, and implementation of the education
material The world of malaria: let´s learn to handle it in the
community.
Methods: The
development of the educational material was carried out in the urban
area of Buenaventura (main city in the Colombian Pacific coast) in
1995. The design was based on the results of a knowledge, beliefs, and
practices study in the city. By using the PRECEDE- PROCEED MODEL
strategy, community groups were brought together with the research team
to design the materials.
Results: The
educational materials were designed according to cultural and
ethnographic characteristics of the population studied. These materials
are table games, comics, videotapes and cassettes, magazines,
altogether in a black bag called «The world of malaria:
let´s learn to handle it in the community».
Conclusions:
This innovative educational material shows that interventions in public
health should be based on results from scientific projects, because
control strategies are based on local realities.

RESUMEN
Objetivo:
Describir el proceso de diseño, validación e
implementación de la estrategia educativa «El mundo de la
malaria».
Métodos:
La estrategia educativa se desarrolló con el modelo de
promoción de la salud PRECEDE-PROCEED. Esta estrategia educativa
se diseñó a partir de los resultados obtenidos en la
investigación sobre conocimientos, actitudes y prácticas
en malaria en la población de Buenaventura en 1995. Los grupos
comunitarios, el grupo de investigación de la División de
Salud de la Fundación FES y los expertos en elaboración
de materiales educativos diseñaron la estrategia.
Resultados: Se
diseñó y validó un conjunto de materiales
educativos acordes con las características culturales y
etnográficas de los habitantes de la región. Los
materiales educativos constan de juegos, formatos de diagnóstico
y seguimiento para el control de la malaria, que se recopilan en un
maletín llamado: «El mundo de la malaria: Aprendamos a
manejarlo en comunidad».
Conclusiones: El
desarrollo e implementación de la estrategia educativa «El
mundo de la malaria: Aprendamos a manejarlo en comunidad» muestra
la importancia de las intervenciones en salud pública basadas en
resultados de investigaciones, lo cual permite generar alternativas de
intervención acordes con las realidades locales.

The American region registered an alarming
progression of malaria during the last twenty years, going from 270,000
cases in 1974 to over 1.14-million cases in 2000. This situation became
a worldwide public health priority, making it necessary to formulate
actions to support malaria control within the local context. Among the
actions suggested are: the Global Strategy for Malaria Control (GSMC)
driven in 1992 and reinforced in 1998 through the Malaria Roll Back
program, which are based on the importance of a locally constructed
risk approach accompany with actions aimed at controlling vector
breeding areas, diagnosis and opportune treatment, the use of bed nets,
and community education as an activity to generate behavioral changes1.
Strategies for malaria control like broad use of 2,2-di(p-chlorophenyl)-1,1,1-trichloroethane (DDT)2,
adequate and opportune use of anti-malaria medications, and the
traditional activities of vertical programs resulted insufficient for
malaria control because of the vector’s resistance to
insecticides and to the parasite’s resistance to medications,
phenomena described since the late 50s and early 60s in Colombia3.
Technical and logistic deficiencies in the
execution of eradication campaigns and reduction of financial resources
destined for national programs, contributed to the resurgence of the
disease. Additionally, other measures like vaccinations have yet to
show sufficient effectiveness in controlling this disease4.
THE CASE OF BUENAVENTURA, COLOMBIA
Buenaventura is the second biggest municipality in the
department of Valle del Cauca; it is also the biggest urban center on
Colombia’s Pacific Coast and the country’s main maritime
port. The urban area, where 82% of its population resides is
administratively divided into 12 communes. Of these, communes 9, 10,
11, and 12 are the areas with the greatest expansion in the
municipality and the principal receptors of displaced and migrant
populations from the rural zone and from other parts of the nation. In
this city, health indicators are similar to those from the
world’s poorest zones and much below national figures. Malaria is
among the top five causes for ambulatory consultation, hospitalization,
and mortality5,6. In 1991, Buenaventura registered an
increase in the number of malaria cases reported, higher than that
reported in the last 15 years. That year, 8,136 cases of malaria were
reported of which 3,296 (40.5%) were registered in the urban zone and
4,377 (53.8%) in the rural zone7.
Since 1958, the activities of the malaria
program in Buenaventura had been executed by the Program for Tropical
Disease (PTD) (previously known as the Malaria Eradication Service),
which conducted spray campaigns, vector controls, along with the
disease’s diagnosis and treatment in urban and rural areas.
To give an answer to the increasing malaria
morbidity, in 1991, through an agreement signed by the Foundation for
Higher Education (Fundación para la Educación Superior)
(FES), Universidad del Valle and the Valle del Cauca Departmental
Secretary of Health, the Health Institute of the Pacific (Instituto de
Salud del Pacífico, INSALPA) was created in Buenaventura. Based
on findings from study of an evaluation of primary health care services
available carried out in ten cities around the nation, in which
Buenaventura had the lowest evaluation in the four components of the
primary health care strategy8, the Institute decided to
promote the development of said strategy in that municipality. Thus,
INSALPA developed the primary health care strategy for malaria control
based on four components: inter-sectorial, community participation,
technological development, and administrative development.
Also, the Institute supported PTD activities
destined for malaria control through the development of
epidemiological, entomological, and clinical research, as well as
administratively and technologically strengthening of the provision of
health services. Support activities for the malaria program began with
a series of diagnostic studies of the malaria situation, bearing in
mind three perspectives: individual, vector, and health services9-11
These research results have helped to identify the zones with the
greatest malaria transmission in the urban area. Furthermore, in such
areas a study was conducted on knowledge, beliefs, and practices (KAP)
on addressing malaria, whose results revealed that age (under 10 years
of age) and the lack of awareness of breeding areas were risk factors
associated with the occurrence of malaria8-11. Based on
these study results and through a community participation process, an
educational program was designed for malaria control.
Study objective. This publication presents the systematization process12
of the design, validation, and implementation of this community
educational program for the purpose of sharing the knowledge obtained
through the experience and contributing to improvement of malaria
prevention practices in Colombia or in other similar contexts.
METHODS
Systematization corresponds to a type of qualitative work, which seeks to critically recover social processes12.
The information was gathered between January and December of 2002 and
included documentary review and semi-structured interviews. The
documentary information and the interviews sought to explore aspects
related to the antecedents, design, validation, and implementation of
the educational strategy. The documentary information was recovered
from archives at the FES Foundation, at the Valle del Cauca
Departmental Secretary of Health, and the Municipal Secretary of Health
in Buenaventura. For the interviews, a convenience sampling was carried
out with key informants, FES Foundation health researchers, educators,
and community leaders who participated in the three stages of the
educational program. Once the participants were identified, telephone
contact was established to let them know of the study’s
objectives, methods, and benefits, to obtain their consent to
participate in an interview, and, finally, to set an appointment for
the interview. The total number of key informants interviewed was 14 of
the 17 planned. The three key informants who did not participate were
out of Colombia during the research.
For the documentary review, matrixes were
designed for information synthesis. A semi-structured guideline was
designed for the interviews. The approximately 1-h long interviews were
recorded and transcribed by using Word version 7.0. For their analysis,
the complete Word transcription was transferred to Etnograph version
5.0, which included reading of texts, selection, and arrangement of the
contents referring to the categories of design, validation, and
implementation. The emerging categories were identified and interpreted
and the results were explained by then cross-referencing said
information with the data obtained from the documentary review.
RESULTS
Antecedents. The
design of the educational strategy was conducted within the framework
of a Primary Health Care Program for malaria control developed in
Buenaventura. From a series of malaria diagnostic studies, using three
perspectives: individual, vector, and health services addressing
malaria, the following aspects were identified: 1) the three communes
(9, 10,11, and 12) in Buenaventura with the greatest transmission rates
of the disease, 2) the main anopheles species related to the
transmition of malaria; 3) the bitting rate and schedule; 4) the
description of the main breeding areas; 5) the knowledge, beliefs, and
practices of the population in Buenaventura in relation to malaria; 6)
the main risk factors associated with the presence of malaria:age and
awareness of the breeding areas8,9.
These research results
were then used to establish three working areas to fight against
malaria: vector control, improved community capacity for diagnosis and
treatment, and community education. This led to suggesting the
following objectives:
· Increase the population’s level of
knowledge on malaria as a health problem and on the necessary measures
for its prevention and management.
· Train community leaders in the components of
malaria prevention and control to diminish the incidence and
complications due to this disease.
· Promote community management processes based on adequate attitudes and practices for local malaria control.
From February 1995
until 1997, staggered activities were implemented every six months to
constitute community groups for vector control and education in
malaria. Twenty-one groups were formed (18 in the urban area and 3 in
the peripheral urban area). An average of 23 individuals participated
in each group, constituting a total of 300 participants. These were
closed groups and the percentage of participation by group members
reached 85.6%. At the same time, mommunity leaders were trained through
workshops aimed at increasing their knowledge on clinical and public
health aspects of the disease, risk factors, and strategies for malaria
control. Simultaneously, during these two years, the group of community
leaders conducted a diagnosis of malaria by neighborhood, established
control priorities, formulated action plans, and elaborated community
projects to control the disease. All of that resulted in the formation
of neighborhood community participation for disease control. It was
during the malaria training of the community groups, that the need to
produce educational material that would contribute to the
population’s better understanding of the disease was more evident.
Design of the educational strategy.
Once was identified the need to produce educational material to support
community interventions being carried out, we invited two professors
from Universidad de Chile, experts in educational material design, who
conducted training on the design of educational materials with
community participation, and participation from INSALPA professionals
and community members.
The design of educational material was based on the PRECEDE- PROCEED model13,14,
which is based on the research-action-participation principle. During
the participative design process of the educational material, the
characterization of the individuals was the most important aspect for
the community. The communities selected characters with afro-descendant
characteristics, which is a reflection of a self representation
process. Furthermore, the drawings were closed to reality and
illustrated every-day life in the Colombian Pacific Coast: typical
housing and wardrobe, preference for bright primary colors, and
exploration of the language used in the zone15. With the
participation of three community groups belonging to the 21
vector-control groups, adjustments were made of regional games and
tales.
Thereafter, an organization specialized in the
production of educational material in the Pacific Coast
(Fundación Habla y Scribe) was hired to adapt the language of
the texts to the local context, using the every-day language of the
community to facilitate comprehension. The sketches were reviewed and
modified with the participation of the INSALPA research group, as well
as of community groups. In December 1995, a final design of the
educational material was done.
Finally, the community groups were called on to
suggest a name for the educational strategy. After many initiatives and
through a voting process, the following name was opted for «The
world of malaria: let’s learn to handle it in the
community» and it was decided that the most adequate presentation
would be a water-proof briefcase adequate for the weather conditions in
the Pacific. As a result, the world of malaria consisted in educational
materials with images consistent with the language, realism, and
colorful characters of the region.
Validation of the educational strategy.
The validation of the educational strategy «The world of malaria:
let’s learn to handle it in the community» consisted in
evaluating if the material was interesting, inclusive, and accepted by
the communities, and if the messages on malaria knowledge, prevention,
and management were clear and understood by the communities of
Buenaventura, who would be the main users of the educational strategy.
This validation was carried out in one Communa 12 and it was coordinated by a psychologist.
Teachers, community workers, health promoters, community leaders,
personnel from the Colombian Institute of Family Welfare, and from the
Municipal Secretary of Health, participated in this phase. These
persons lead the meetings for the use of the educational material with
different groups. These groups met in homes, community halls, health
centers, or at the homes of the community agents. The educational
material was used in these meetings and the participants aired their
opinions on the materials, their characters, the acceptance and
comprehension levels of the educational material, and the adjustments
that needed to be done to such to make it more understandable and
useful.
Implementation of the educational strategy. For
the implementation of this educational program, a series of processes
were designed encompassing: 1) training of community leaders with
special emphasis on opportune diagnosis and self medication, 2)
training in activities to facilitate or replicate knowledge on malaria,
3) planning and execution of activities to manage breeding areas, and
in the creation of micro-enterprises dedicated to the manufacture of
bed nets impregnated with insecticides, 4) training of some leaders in
obtaining and interpreting the thick blood smear exam, and in providing
malaria treatment. Likewise, a series of instruments were designed to
test participant knowledge, to obtain information of the local
communities, leaders profiles, and activities for disease control,
which have become the materials for the evaluations performed on the
educational program whose results have already been presented in other
publications16-18.
The educational material.
The main result of the process developed was the design and validation
of an educational material called «The world of malaria:
let’s learn to handle it in the community», created for use
by health promoters and volunteers, school teachers, community mothers,
and leaders from community organizations. The material was created to
be use as a primary prevention tool with the possibility of positively
influencing participatory processes for malaria control. The
educational material include a set of 17 educational tools, namely:
Participative guideline. It
is a consultation booklet for the educational leader which provides
methodological guidelines to develop training workshops on malaria with
the community.
Booklet «Let’s learn about malaria or paludism». This booklet introduces the basic clinical and epidemiological concepts on malaria to guide the educational leader.
Video forum and audio cassette. This
is a two-part video. The first part shows a dramatization of a case of
malaria in a community, highlighting the way the malaria case should be
handled and the community organization alternatives for prevention
(control of breeding areas, use of insect repellents, and bed nets).
The second part present the community organization processes for
malaria control, especially the constitution of a cooperative
organization to make bed nets and conducting community activities for
adequate environmental management (control of breeding areas and brush
clearing). Both the video and the audio cassette performance were made
with the participation of the communities from the municipality of
Buenaventura. The VHS video presentation lasts 20 minutes.
Cartoon «Let’s learn about malaria or paludism». This material presents cartoons of the video and audio contents; designed for communities lacking electronic equipment.
Tale of doña Anofelina. This
material aim to identifying the Anopheles mosquito and its life cycle.
It targets mainly the childhood population whom shouldplay the tale
after reading the material.
Educational games.
The four educational games correspond to: What do we know? A game to
identify how much do the participants know about malaria. Parcheesi, an
individual game made up of cards or indications on individual and
collective positive and negative behaviors on malaria control. Bingo
and Snakes and Ladders are didactic games, which aid in reinforcing and
evaluating knowledge acquired on malaria during the training workshop.
Posters. These
tools serve as support to explain the issue of malaria, especially that
referring to the main players, its cycle inside the human body, and
prevention measures.
Flip charts.
This material is used by the leader in the training process. The
materials refer to symptoms of malaria, the mosquito’s life
cycle, and types of breeding areas for Anopheles; different insect
species, and mapping of malaria cases.
Achievements.
With the implementation of the educational strategy community vector
control processes were generated, where 257 individuals of the 300 who
initially participated in the design process, were trained during 85
sessions on basic aspects of malaria prevention and control. With these
individuals, 50 breeding areas were eliminated and 72 workdays were
used in brush clearing. Furthermore, 405 bed nets were made and
distributed and 10 days of impregnation were completed. Additionally,
29 community projects were elaborated to identify and eliminate
breeding areas and to teach the community about malaria; a community
fund was created and 353 accounting and administrative training
sessions were carried out that constitute the base of the formation of
community groups.
The educational strategy is being integrated
onto activities of urban and rural malaria control at the national
level in municipalities of Valle del Cauca, Nariño, and
Chocó; especially, in activities of Malaria Control Programs in
these departments, in Basic Attention Plans – now known as
Collective Intervention Health Plan, and in Nariño, mainly, in
the alliance established between the Departmental Health and Education
Secretaries of Nariño where teachers from malaria infected zones
in the department were trained to include them in the educational
strategy in institutional educational projects.
Through this educational strategy, community
educators from Fundación FES Social have trained a total of 2772
new leaders in 359 locations from the rural area and urban centers in
the Pacific region of Nariño, Buenaventura, Chocó,
Putumayo, and Amazonas in Colombia; and in Arismendi and Benítez
in State of Sucre in Venezuela, of which 30% are health promoters, 24%
microscopy specialists, 17% leaders from community organizations, 20%
schoolteachers, and 9% community mothers, and a total of 2772
briefcases of the World of Malaria have been distributed throughout
these regions.
This educational strategy evaluates knowledge on
malaria through pre-tests and post-tests given to leaders trained.
During the years of strategy implementation, it has been possible to
establish the percentage of correct answers in the pre-test and
post-test; the pre-test of knowledge on malaria has gone from 20 to 50%
right answers and the post-test has reported 80 to 90% right answers,
evidencing increased knowledge.
A total of 518 community malaria control
projects (mass distribution of the preventive message, control of
breeding areas, brush clearing, filling of wells, drains, and
fumigation) have been developed and executed by leaders in the
communities. In a follow up after 3, 6, and 12 months of implementation
of the control projects, it was found that 73% (378) of the projects
were totally executed, 19% (99) partially, and 8% (41) had no type of
execution with respect to the activities planned during training. This
strategy has been characteristic of creating capacities in leaders and
communities where it has been implemented, given that these community
projects have been developed in 90% of the times with the
community’s own resources.
Though the three annual follow-up activities
conducted on those responsible for multiplying the effort (replicators)
after the initial training with the strategy’s educational
materials, we were able to prove by reviewing follow-up forms collected
by the replicators the number of individuals trained by them, the
number of activities to manage breeding areas with the community, the
types of activities carried out (workshop, visit), and the population
group for whom the activity is aimed; in all, the replicator
facilitated knowledge to 10,647 people.
DISCUSSION
Worldwide experiences reveal that community
participation is a key element in health promotion and prevention of
the disease to maintain or modify life styles and community
environments to generate healthier life styles. Communities more
involved and committed with health decision making show greater results
in terms of their health19.
Clear examples showing that community
participation is essential in obtaining favorable results for human
health are the Carelia Projects in Northern Finland in which mortality
via ischemic cardiopathy was reduced by 50%; or initiatives like those
developed in Vietnam, Honduras, and Mexico where provincial and
community policies were established to control water containers to
control propagation of Aedes larvae, among others20,22.
Likewise, a national survey in Colombia on malaria control in 184
endemic municipalities reveals important community participation in
activities like control of breeding areas with 34% participation and
promotion of the use of insecticide-impregnated bed nets at 14%3.
Promoting the development and implementation of
strategies with community participation is, among others, one of the
WHO’s recommendations for malaria control1. The
worldwide initiative called «Roll Back Malaria» has
insisted on calling on communities for opportune diagnosis, adherence
to malaria treatment, and development and consolidation of control
programs.
The focus of community participation has been
driven by the Colombian government as a fundamental tool for
communities at risk to become aware of malaria a problem and an
obstacle for their wellbeing, and for the construction -along with
health services- of real actions for its control2. Within
this framework, we register the process developed for the design and
implementation of an educational strategy for malaria control
«The world of malaria: let’s learn to handle it in the
community», presented in this document.
This process accomplished the design of
educational material according to local characteristics, permitting
acceptance within communities and local health agents, as described in
the evaluation of processes made on the implementation of the
educational strategy, who consider that said educational tool is a
major support for local malaria control (Observaciones no publicadas).
The strategy used the PRECEDE-PROCEED health promotion model13,
which permitted planning an educational intervention against malaria,
supported by Research-Action-Participation (RAP), which from a general
diagnosis carried out by the community, advanced to the design and
implementation of educational processes with the community.
Similar developments, also in Colombia, have
been implemented. This is the case for the department of Chocó
where an educational intervention was conducted with interactive games,
yielding increased levels of knowledge with respect to malaria, its
symptoms, and the use of anti-malaria medications23,24.
Also, Nicaragua has developed programs based on
community health education, insecticide impregnation of bed nets, and
administration of anti-malaria medications with community volunteers,
as key tools to strengthen the inclusion of communities in health
actions related to malaria control23-25.
The malaria educational experience developed in
Buenaventura presents the relevance of conducting interactions between
researchers and communities, which permit real social appropriation of
knowledge to design interventions in public health based on scientific
evidence, enabling the generation of intervention alternatives
according to reality15.
However, in spite of the responsibility of
health services in promoting community participation in disease
control, we still find within these institutions a not very active,
propositional, and committed role with the processes, which in some
instances hinders the sustainability of these types of exercises over
time.
The bibliographic review became a limitation for
the enrichment of the discussion, because of the rather limited number
of publications and systematization of work related to the design and
development of health educational material with community
participation.
This systematization process12
contributed to the documentation and reconstruction of facts surging
during design, validation, and intervention of the malaria educational
program. And it became a secondary source consultation material for the
development of effectiveness evaluations and implementation processes
of the malaria control activities proposed by community leaders trained
with the strategy and for the cost-effectiveness evaluation of the
strategy at institutional and family levels, which observed the
financial investment versus the number of malaria cases avoided with
respect to the implementation of the strategy (Observaciones no
publicadas)16-18.
The limitations in this study consisted in not
having done all the interviews programmed, because three of the key
characters were out of the country, as well as not broadening and
enriching the document due to the restriction of some aspects in the
continuity processes of the memories of the interviewees.
This educational strategy was internationally
recognized in 2009 by the Pan American Health Organization, obtaining
third place in Latin America as «Champions against malaria in the
Americas».
Finally, this article demonstrates how designs
of health education strategies for promotion and prevention may be
developed with active community participation.
