Forewordhe Government of Thailand emphasizes that accessibility to health care is afundamental human right that must be available to all citizens. Although allThai citizens are entitled to the State Health Insurance Programme, a number ofservices critical to the prevention of ailments remain out of reach. Workers, forinstance, often suffer from problems associated with bad working conditions andunsafe environments; yet they are not able to receive occupational diagnosis andrehabilitation services from the present health system since the capacities arelimited.Primary care units (PCUs) are in the frontline of Thailand’s healthestablishment and are the most accessible to people working in communities andlocal clusters. Based in villages, PCUs carry out health promotion, prevention,medical treatment and rehabilitation services. They are less trained, however,in detecting and addressing occupational health problems and are dependenton few experts based in the provincial or regional offices. Where working peoplespend more than half of their wake time at work, it is expected that many of theailments and incidences presented to the primary care units are rooted in theworkplace.Following the Ministry of Public Health’s (MoPH) initiative to develop PCUcapacities on occupational health services, the ILO-sponsored Informal Economy,Poverty, and Employment Project supported a one-year pilot programme incollaboration with the MoPH and 15 local health units in five provinces. Thisreport details this experience and draws lessons for its replication in Thailand andin other countries. In particular, it summarizes findings from risk assessments ofagricultural and home workers in the five pilot provinces of Thailand. It describes,based on a survey conducted during this collaboration, capacity and level ofawareness of PCU staff on occupational health services. It also draws lessonsfrom training and outreach activities initiated by the PCUs. It also shows howhealth units are the not the only change agents in communities; rather, localdistrict offices and employers and workers organizations play a critical role inframing real solutions that address root causes of workplace hazards.This initiative was carried out in line with ILO’s priority of addressing decentwork deficits based on the four components that define decent work, namely:rights, employment, social protection, organization and representation. Themandate to extend this priority to the informal economy was reaffirmed in the2002 International Labour Conference. Furthermore, specific ILO conventionsT3

such as Convention 151, Occupational Safety and Health Convention (1981);Convention 181, Occupational Health Services Convention (1985); Convention187, Promotional Framework for Occupational Safety and Health Convention(2006), mandate governments to promote the right of workers to a safe andhealthy working environment and to establish national policies, programmes andservices on OSH. Convention 187 in particular calls upon governments to establish,through appropriate laws, agencies and mechanisms, a national system of OSHsupport that would involve, among others, information and advisory services; OSHtraining; occupational health services; research, data collection on occupationalinjuries and diseases; collaboration with insurance systems and, notably, “supportmechanisms for a progressive improvement of occupational safety and healthconditions in micro-enterprises, in small and medium-sized enterprises and inthe informal economy.”The task of extending services to the informal economy where peopleare found in non-traditional work places can lie beyond the institutional reachof labour ministries. Collaboration with the health and agricultural ministries, inparticular through village-based health units and agricultural extension workers,are increasingly viewed as an effective way of augmenting the reach of labouradvisory bodies to workplaces found in homes, farms, local markets, streets andmicro enterprises. Their effectiveness is helped in part by their image, not asmonitoring authorities, but as health promoters and farm advisers. Indeed suchan inter-agency collaboration can be part of a national system of OSH promotionthat can potentially cover a wider reach.This documentation is a product of a very extensive collaboration underthe leadership of the Ministry of Public Health and involving the dynamicparticipation of 15 health units throughout the Thailand. Our gratitude goes tothe project leader, Dr. Somkiat Siriratanapluek of the Bureau of Occupationaland Environmental Disease, Department of Disease Control of the Ministry ofPublic Health. Apart from spearheading this initiative, animating public healthpersonnel nationwide, and preparing this report, Dr. Somkiat also collaboratedwith ILO in various knowledge sharing events involving similar projects of the ILOin Asia, Africa, and Latin America.Thanks also goes to Ms. Juraiwan Siriratana, also of the Bureau ofOccupational and Environmental Disease, Department of the Disease Control,Ministry of Public Health, who coordinated the activities under this project and4

helped in monitoring the results. Ms. Pensri Anantagulnathee translated all thereports into English, which was critical to the collaboration with ILO, and so thata wider audience could be reached. Various health officers in the pilot PCUs areresponsible for the experiences reported in this document. Without their creativityand initiative, we would not possibly have such a collection of experiences as wenow have that can form part of a viable national solution.Many thanks go to Dr. Mei Zegers who collaborated with the Ministry ofPublic Health in finalizing this report. Mr. Tsuyoshi Kawakami, Senior Specialiston Occupational Safety and Health of the Subregional Office for East Asia inBangkok, and Mr. William Salter, Director, a.i., of the Conditions of Work andEmployment Programme (TRAVAIL) in Geneva, provided valuable advice andcomments on the design and implementation of this project.The partnership between ILO and MOPH, including the preparation of thisreport, was initiated and overseen by the project team of the Informal Economy,Poverty and Employment in Thailand. It was closely coordinated by Ms. RakawinLeechanavanichpan, the National Project Coordinator, and backstopped byMs. Sandra Yu, Chief Technical Advisor. Ms. Ginette Forgues, Senior Specialiston Local Strategies for Decent Work provided valuable technical support inthis collaboration and in all of the initiatives of the IE Project. Ms. PaveenaEakthanakit provided efficient administrative support and Mr. MatthewHengesbaugh provided editing and logistical support towards the preparationof this publication.We hope that the knowledge and experience gained from this project,as described in this report, can motivate the rest of Thailand as well as othercountries in exploring similar partnerships especially where PCUs or similarbodies might be mobilized to extend critical OSH services.Jiyuan WangOfficer-in-ChargeILO Subregional Office for East AsiaBangkok, Thailand5

Integrating Occupational Health Services into Public Health SystemsA Model Developed with Thailand’s Primary Care UnitsExecutive SummaryThe development of an occupational and environmental healthservices model that can be integrated into public health systems is animportant step towards improving workers’ physical and mental health.The goals of such a model are to provide primary medical treatmentand/or referral, support rehabilitation, decrease occupational risk factors,promote good health practices, control occupational diseases and itshazards, and track epidemiological data for further analysis of occupationalillnesses and accident rates.Thailand’s Ministry of Public Health (MoPH) developed such a modelwith support from the ILO. The MoPH referred to key ILO standards such asConvention 161 on occupational health services during the development ofthe model.The model discussed in this report was developed, successfully tested,and can serve to inspire other countries to adapt and implement a similarprogramme.The MoPH carried out a research and development project to createthe model in stages:1) Analysis of the existing situation of occupational and environmentaldiseases prevention and control activities of provincial health officesand primary care units (PCUs) in Thailand.2) Data collection to provide baseline data and inform the developmentof an occupational and environmental health services trainingcurriculum for capacity building for the PCU staff.3) Pilot test the provision of occupational safety and health (OSH)services in PCU.4) Monitor the process throughout implementation of all steps andevaluate effectiveness of the model.Data was collected on occupational disease prevention and controlactivities from 75 provincial health offices and from the PCUs in five pilotprovinces: Nakornpathom, Suphanburi, Khon Kaen, Lamphun, andPhayao.11

Integrating Occupational Health Services into Public Health SystemsA Model Developed with Thailand’s Primary Care UnitsThe PCU staff in the five pilot provinces OSH services implementedthe model with technical support from their provincial health office and thePCU network.Analysis of the baseline study results indicated that occupationaldisease prevention and control activities provided at provincial level needto be targeted to underserved populations such as agricultural and informaleconomy workers.OSH services were integrated into existing health services provided bythe PCUs. Specific activities incorporated into the areas of responsibility ofthe PCUs included: collection of patient work history; job characteristics; recording of data on illness/accident information into family recordsfolder; identification of work hazards by using a risk assessment form andhealth record for employees aged 15 years old and over; implementation of activities promoting occupational health in thecommunity through participation of community and workers; collection and analysis of data; prioritisation of problems and problem solving; monitoring of activities at the regional, provincial, and central level.1 (p-value 0.000).12The project included the development of a five-day training course on OSHservices for the PCU staff in five pilot sites. Participants benefited substantiallyfrom the training as indicated by a post-training test.1 The test results indicatedthat the trainees were able to correctly identify occupational health hazards, assessand indicate factors in controlling occupational risks, and provide appropriatehealth services.The pilot project included activities implemented in the community andthrough outpatient services provided in PCUs.Activities implemented in communities included workplace surveys,participatory data analysis, and communication of survey results to workers forjoint problem solving. Workplace surveys and evaluation of the workingenvironment included general health examinations and screening foroccupational diseases such as pesticide poisoning screening tests foragricultural work groups. Specific strategies to solve problems encountered inagriculture were also implemented.The implementation of OSH services in the community was carried outwith agricultural work groups in seven villages and with community workers inthree villages.Occupational disease prevention and control activities provided at thePCUs included primary medical treatment, finger tip screening test for pesticidepoisoning, health education, and surveys. The most common occupationalhealth problems identified were occupational skin diseases caused bychemicals, musculo-skeletal disorders, accidents, and eye-strain.

Executive SummaryIn conclusion, results from the pilot model on OSH services from 10 PCUsindicate that the PCU staff now have the capacity to provide OSH servicesand related health promotion activities to workers. Capacity was strengthenedto provide community-based services for workers and outpatients. Provincialhealth personnel capacity was also strengthened to provide better support tothe PCU.Continued capacity building to increase knowledge and skills for the healthcare staff will be needed. Advocacy is necessary to create a national policyto integrate the model into the work of remaining PCUs and will need to besupported by sufficient budget and other resources. Once approved, capacitywill need to be developed in all PCUs throughout the country. Identificationof roles and responsibilities as well as development of implementation networkswill be required. Awareness raising among local authorities with respect tooccupational health issues is necessary so that they can become a majorpartner in supporting PCU activities.13

Integrating Occupational Health Services into Public Health SystemsA Model Developed with Thailand’s Primary Care UnitsDefinitions of Selected TermsHealth education: refers to consciously constructed opportunities for learninginvolving some form of communication designed to improve health literacy,including improving knowledge, and developing life skills which are conducive toindividual and community health.2Health promotion is a strategy for improving the health of the population byproviding individuals, groups and communities with the tools to make informeddecisions about their well-being. Moving beyond the traditional treatment ofillness and injury, health promotion efforts are centered primarily on the social,physical, economic and political factors that affect health, and include suchactivities as the promotion of physical fitness, healthy living and good nutrition.Emphasis is placed on collaborative work with different partners.3Health protection involves the development and implementation of directregulations and other strategies aimed at protecting the health of the people(of a country) against proven health risks over which they, by themselves, havelittle or no control.4Health services refers to services provided to the public that meets their healthneeds and provides solutions to health problems in order to increase quality oflife through improved physical and mental health.Contracting Unit for Primary Care (CUP) is a health service unit that is contractedby the province to be the main deliverer of health care to its registeredpopulation.2 WHO, Health PromotionGlossary, WHO/HRP/98.1; Geneva: 1998.3 Pubic Health Agencyof Canada, lossary.html. accessed 14-052006.4 ibid.5 ibid.16Primary Care Unit (PCU) is a public health service unit that works withcommunities, families, and individuals to identify health needs and assets,and supports individual and community action to prevent illness, protect andpromote health, and achieve well being.Prevention is a method of averting health problems (e.g. disease, injury)through interventions. Preventing and reducing the incidence of illness andinjury may be accomplished through three mechanisms: activities gearedtoward reducing factors leading to health problems; activities involving theearly detection of, and intervention in, the potential development or occurrenceof a health problem; and activities focusing on the treatment of health problemsand the prevention of further deterioration and recurrence.5
