As knowledge about the health impacts of exposure to occupational and environmental chemicals increases, wellness professionals and other interested individuals need to it is in able to accessibility and use resources that carry out timely and also accurate toxicology and environmental health and wellness information in an efficient and obtainable manner. To better understand the toxicology and also environmental wellness information requirements of health and wellness professionals and also the methods through which they situate this information, the committee the evaluation the published literary works (which deals mainly with physicians and their general methods of seeking information) and focused top top those issues certain to toxicology and environmental wellness information by receiving input from health experts through emphasis group discussions (see appendix C), data built up from the questionnaire (see appendix B), and committee discussions with colleagues and other health professionals.


In 1967, R.E. Maizell approximated that the half-life the the current information known by scientists, engineers, and health experts was close to 10 years; that is, in 10 years fifty percent of what is learned by those in technical areas will become obsolete, and fifty percent of what such specialists will require to recognize is no yet available (Maizell, 1967). Advances in technology continue to rise the expansion of biomedical information at such a rapid rate that health specialists cannot maybe absorb and also retain all of the details available. However, the development of online details resources, such as the TEHIP databases, have the potential to alleviate this difficulty by giving a frame for storing, processing, and also retrieving essential information. It climate becomes necessary to completely understand the info needs the health experts so that the correct info is gathered and stored in an accessible manner. Thus, the ability to define the details needs that health professionals (although not well-studied) is vital to the development of systems that will support their needs.

Why Health experts Need Information

The information needs the health experts stem native a range of components including patient care, patient education, experienced curiosity, and also research. Additionally, the rapid developments in an innovation and scientific research have broadened the understanding base in all areas of medicine and health care.

In 1991, Osheroff and colleagues occurred a typology that assesses the info needs of wellness professionals, particularly physicians, by examining the concerns posed during clinical teaching. Lock concluded that details needs are thrust by the level of a patient"s problem, a patient"s inquiry, the professional"s understanding base, and also his or she level the awareness of accessible resources and curiosity to uncover out much more information. The study characterized the details needs of health professionals in terms of three components: (1) info that is essential for decision making and also that is currently known by the health experienced (currently satisfied needs); (2) info that is not known by the health and wellness professional but that that or she recognizes together being applicable to the decision-making process (consciously well-known needs); and also (3) details that is essential to the circumstances at your disposal but that the health experienced does no realize is applicable (unrecognized needs) (Osheroff et al., 1991).

Williams and colleagues (1992) categorized the information needs the health specialists by the reason that health and wellness professionals start their search for information, to:

confirm or disconfirm existing knowledge;
assist in resolving a new or unfamiliar health care problem;
update straightforward knowledge top top a topic v review;
obtain details from an additional specialty when dealing with a patient or person with lot of problems;
determine even if it is a knowledge void exists in the literature and also whether a brand-new research job or publication have to be planned; or

Information required by health and wellness Professionals

The type of info needed by health specialists is dependent on many factors, including the object or worry in question, the knowledge base that the wellness professional, his or she awareness of info sources, the linked costs of obtaining information, and also the purpose for which the information will be used. The "trigger" or beginning point because that conducting a find for information varies widely amongst health professionals. Emphasis group participants indicated that most of your inquiries connected to environmental health information begin with the name of a chemistry substance or with symptoms potentially linked with a known exposure (Appendix C). Because that example, emergency room and also primary care professionals declared that they frequently need to "translate" the brand surname of a family members product into the clinical chemical name before beginning a common beginning points included the ar of work, kind of job, or geographic location (see also Chapter 6).

A 1988 IOM committee examined the farming occupational and environmental info needs of wellness professionals, particularly of primary treatment physicians, and also formulated a perform of details search. Other needs that included: causative agents of occupational and environmental illnesses; signs, symptoms, and diagnosis of and treatment because that occupational and also environmental illnesses; nonclinical and supportive interventions; and an illness and exposure trends within the neighborhood (IOM, 1988).

Once an info need has actually been identified, determining who actually conducts the info search relies on a number of factors, including having the capability to command a database search (access to the database and the knowledge compelled to conduct the search); having time easily accessible to conduct the search; and determining even if it is a high worth is placed on seeing the data and information easily accessible and following leads and also data "trails." focus groups shown that specialists and researchers in toxicology and environmental health, and also information specialists, public health officials, educators, and also students, are an ext likely to command searches themselves, whereas medical professionals in general or health experts working in nontoxicology-related areas are most likely to have actually others conduct a find for them.


When health experts make a decision on whether to seek an information query, they need to weight and also reach a compromise in between a variety of conflicting components including the require for the information and also the linked costs the locating the details such as the time, effort, and also financial costs connected in details seeking (Connelly et al., 1990). Huth (1985) analyzed information-seeking techniques in regards to a utility-cost analysis. In this strategy (as viewed below), the value of the information resource depends top top the utility of the retrieved information (its relevance, thoroughness, and the performance with which the is retrieved) together it relates come the costs necessary to obtain the information (including the purchase cost and time and other accessibility costs).


Studies top top the information-seeking habits of health professionals have found that colleagues and reference books are frequently the details resources that health professionals an initial turn to through an information query (Blackwelder and also Dimitroff, 1996; Covell et al., 1985; Curley et al., 1990; Williamson et al., 1989). The access costs are minimal, and the relevance and efficiency room usually high. A recent study of nurses, physicians, pharmacists, occupational and physical therapists, and also other wellness professionals found that 45 percent would very first consult a colleague to prize an info query, 28 percent would very first use an individual files and also reference collections, and 17 percent would an initial consult a librarian (Blackwelder and Dimitroff, 1996). Similarly, a 1990 survey revealed that registered nurses sought info from partner 45 percent of the time, consulted written resources 45 percent that the time, and also used other resources consisting of databases 10 percent of the time (Corcoran-Perry and also Graves, 1990). Participants in the emphasis group discussions (see appendix C) identified comparable factors influencing the way in i beg your pardon they locate information. A variety of studies have shown that owing to a organize of factors, including lack that awareness, access, training, and also time, countless health specialists have not emerged effective and efficient information-seeking habits that expand past colleagues and textbooks (Covell et al., 1985; Haynes et al., 1990; Williamson et al., 1989; Woolf and also Benson, 1989). Researches of younger health professionals who have consistently used computers during your education and training display that lock are an ext likely to find the medical literature online, whereas countless older experts are more likely to it is in unfamiliar with looking online databases and also tend to rotate to colleagues and also textbooks for details (Gruppen, 1990; King, 1987; Lockyer et al., 1985; Osiobe, 1985).

The adhering to sections talk about a variety of the components that influence information-seeking habits in wellness professionals. An understanding of these components is an essential for the development of future info resources that finest serve the varied information needs of wellness professionals.


Although present health professionals show up to be in a transition phase about computer use, the brand-new generation that young health specialists is an ext computer literate and much more reliant on computer systems for many different type of information. Countless current medical and also nursing students spent their high school and college careers using computers for school and recreation. College libraries at all levels have actually online library catalogs, and the use of computer systems in schools has actually been boosting rapidly.1 In the next 10 years, there will be a dramatic change in student computer system expertise, in computer familiarity, and in the presumption on the component of students that details is an ext easily situated online than in recommendation books. This an altering dynamic will have a significant impact on computer utilization an abilities and on the extent of digital database searching.

Work or practice Setting

The work atmosphere or practice setup also influence the information-seeking actions of wellness professionals. Over there are wide variations in between work settings in the methods that health experts have to accessibility online databases and computer networking capabilities. Health experts in smaller sized work environments or exercise settings (e.g., clinics and private practices) often tend to rely an ext heavily on not blocked sources, such as colleagues, and minimal formal sources, consisting of textbooks and also handbooks (Dalrymple, 1990). Back health specialists working in academic settings or in larger clinics and hospitals associated with clinical schools or research organizations still refer to textbooks and also colleagues frequently, they are an ext likely to have access to health science libraries and extensive computer system networks (Dalrymple, 1990; Gruppen, 1990; Osiobe, 1985). As computers continue to become an ext commonplace in every health care settings, accessibility to online resources will no much longer be an concern of concern.

Time Sensitivity and Level of Detail

The time sensitivity factor, or exactly how quickly solution is required, is closely correlated come the level of detail needed and also the type of information resource consulted. Fan to time constraints, health experts working in patient treatment require info resources that space readily accessible so information can be effectively retrieved (e.g., colleagues, textbooks, and also handbooks). These health specialists often need a an introduction of known info (e.g., summary information on a particular chemical and also its effects) that accurately answers their inquiries (Cohen et al., 1982; Northup et al., 1983; Osiobe, 1985). This is particularly true in emergency treatment situations. When an emergency room doctor encounters a patient who has swallowed a household cleaning product, that doctor needs prompt factual data (i.e., What product was swallowed? What room the harmful ingredients in the product?) and also detailed treatment management information.

On the various other hand, health and wellness professionals affiliated in research, plan development, and other tasks that enable for a greater length the time come be devoted to locating details will frequently require an extensive retrieval, an exhaustive find of the literature, and the use of detailed sources of details (Cohen et al., 1982; Northup et al., 1983; Osiobe, 1985; Wallingford et al., 1990). Additionally, they space most most likely not to want summarized information but rather are in search of original data native which castle can draw their own conclusions or hypotheses. For example, a study of physicians" usage of medical information resources uncovered that 73 percent the the respondents shown a willingness to spend in between 10 and 30 minutes on computer system searches (Woolf and also Benson, 1989). However, most of this physicians indicated that they would certainly devote this quantity of time come conducting research, but not come making clinical decisions. Digital databases have the right to serve both the acute and long-term information needs that health professionals if systems room designed through those factors in mind.


In addition to the expenditure the the wellness professional"s time involved in locating information, the financial costs of digital searching may be a element in determining what sources of info are consulted (Curley et al., 1990; Dalrymple, 1990). Since online charges typically are figured out both by the lot of time spent online (the per-minute affix time) and also by the lot of information retrieved online, understanding of the database and expertise in emerging relevant search methods relate straight to the last costs. Because online costs are an overwhelming to determine ahead the time, health experts may like to use CD-ROM resources, which allow for unlimited searching for addressed costs. The extent to which find costs impact searching of online databases as well as potential techniques to leveling pricing frameworks (thereby giving the user with cost estimates at the outset of the search) need to be considered in future studies.

Accessibility and also Relevance

Ease of access and the relationship of the data retrieved are necessary considerations as soon as seeking information and solutions to diagnostic and treatment problems. The use of textbooks and journals is easy and convenient for most practitioners. Furthermore, discussing a situation with a reliable colleague, particularly one who has examined a similar case, may provide more relevance come the instance at hand. These are classic methods of obtaining information, particularly among many current medical professionals who were no trained in the use of online resources and also who are not conscious of the services of digital searching.

Searching a computer system database usually outcomes in an ext extensive amounts of information, if not always fully relevant information,2 and comprehensive benefits come the patients. Numerous studies have actually demonstrated the services of online literature searching to the patients once health experts have consulted online databases for added or the many up-to-date information on diagnosis, treatment, and prevention (Haynes et al., 1990; King, 1987; Marshall, 1992). The retrieved information impacted patient treatment in a positive method by an altering the means in i beg your pardon a situation was handled, contributing come a better-informed clinical decision, or leading to higher-quality patient care. In 1994, Klein and colleagues check the association in between the use of MEDLINE searches by health care professionals and also economic indications of hospital costs, charges, and also length of remain for inpatients. For the patients who health experts used MEDLINE and conducted literary works searches at an early stage in the patients" stay, costs and lengths of continue to be were substantially lower 보다 those because that patients whose health professionals performed searches later on or no at every (Klein et al., 1994; Lindberg et al., 1993).

Health specialists may no be mindful of these benefits. Health treatment trends such as the usage of evidence-based medicine approaches that emphasize combine the biomedical literature into clinical decision make may provide an catalyst for enhanced searching the bibliographic databases.


The complying with section examines statistics on existing TEHIP users and also then focuses on potential users, mentioning their details needs, the information sources that are currently being consulted because that toxicology and also environmental health and wellness information, barriers to using the TEHIP databases, and also opportunities that may boost the use of TEHIP databases. Potential users incorporate all health and wellness professionals and other connected user areas that might advantage from utilizing the TEHIP databases together a source for toxicology and also environmental health and wellness information.

Current Users

Toxicology and also environmental wellness information is offered by experts working in a number of fields, including chemical manufacturing, pharmaceutical development, transportation of hazardous materials, eco-friendly law, public advocacy, nursing, and also clinical medicine. The general public, as debated in chapter 1, is additionally concerned about the adverse health impacts from chemicals and environmental exposures, such together lead, radon, pesticides, smog, dioxin, and carbon monoxide, and also may request extr information from their health care professionals or seek out the details themselves.

Only partial statistics top top the current use that the databases room available. does have statistics on searches conducted on the servers, however, because licenses its databases for tape, online, and also CD-ROM accessibility through commercial vendors, universities, and other institutions (see chapter 6) finish statistics on every searches that the databases are not available. A current survey of 2,500 online customers of the databases (on the servers) discovered that 46 percent of the users are wellness professionals, 20 percent room librarians, and also 19 percent are researchers (, 1996). This is in comparison to statistics on usage of the TEHIP databases3 (on the servers), which indicate that the primary users room in industry, with health and wellness professionals audit for just a minor percent of users. In 1995, 37 percent that the individuals of HSDB were established as being from industry, whereas only 6 percent were from the health care community (data provided by committed Information solutions Division, Other TEHIP databases reported comparable distributions of users.

MEDLINE is widely provided in the health care community together the source for bibliographic citations that the biomedical literature, and training on browsing MEDLINE is consisted of in the curricula of plenty of health expert schools. Statistics top top searches the the servers show that, as might be expected, the use of MEDLINE much exceeds the usage of committed MEDLARS databases. statistics suggest that in 1995 there to be 5,262,329 digital searches that MEDLINE, 71,631 that TOXLINE, 30,296 the HSDB, 17,593 of IRIS, 12,793 of TRI, 33,427 of DIRLINE, and 13,808 of RTECS (, 1997).4 MEDLINE includes only minimal toxicology and environmental health-related details (including case reports, human toxicity levels, epidemiological studies, and literature reviews).

Potential Users

The committee disputed the health and wellness professional communities that potentially have information requirements in toxicology and environmental health and use for the details in the TEHIP databases (Box 4.1). The committee take it a vast perspective that includes a variety of groups through interests in environmental health (Chapter 1). The committee realizes that the health professional ar does not have homogeneous information needs and that there is vast variation in accessibility to digital databases and also other information resources. Also with these variations, however, the committee thought that it was worthwhile to talk about potential user communities to carry out generalized insights into just how might better meet the toxicology and environmental health and wellness information requirements of this groups. The complying with list of potential user neighborhoods is not expected to be definitive or exhaustive yet rather was supplied by the committee for purposes of discussion:


BOX 4.1

Examples that the Applicability of the TEHIP Databases because that the work of health and wellness Professionals. CLINICALLY RELEVANT info Information the has direct clinical relevance includes the emergency medical treatment information and also the human being toxicity recaps (more...)

primary treatment professionals (e.g., physicians, nurses, nurse practitioners, and physician assistants) and also pharmacists;
specialists in occupational and environmental wellness (physicians, nurses, nurse practitioners, medical professional assistants, industrial hygienists, and safety officers);
emergency medicine and poison control facility personnel (e.g., emergency room wellness professionals, emergency medical technicians, clinical and medical toxicologists, and specialists in poison information);
health science librarians and also faculty at health professional schools (including medical, nursing, publicly health, pharmacy, and also dental schools);
environmental wellness researchers and scientists (including health and wellness physicists, epidemiologists, toxicologists, and also forensic practitioners);
patients, the general public, and also community organizations (including regional emergency to plan committees, public librarians, educators, and advocacy and activist organizations); and
health professionals in local public health departments or in state and also federal organ (e.g., policy advisors, wellness educators, and public clinic personnel).

Although the type, depth, and frequency the toxicology and environmental wellness information required by every of these groups will differ amongst individuals within and across the groups, depending upon job responsibilities, demographics, training, work or exercise setting, time, access, and also availability, this groupings carry out a structure from i m sorry to explore information needs, existing strategies for finding information, and also potential use of the TEHIP databases. The generalizations presented below draw ~ above input listed to the committee from emphasis group discussions, responses come the committee questionnaire, and discussions through colleagues and also other health and wellness professionals. They room presented here as instances from i m sorry some general conclusions might be made.

Primary treatment Professionals

Information needs. Health care professionals in family members health, pediatric health, and women"s health and wellness are frequently the an initial point of call for patient with ecological health questions and also concerns. Primary treatment professionals frequently expressed a need for summarized info that they might then provide to patients. For example, pediatricians and pediatric nurse practitioners are frequently asked questions on ecological health exposures by breast-feeding mothers and also by mother concerned about the results of exposure to hazardous substances throughout pregnancy. An ext infrequently but demanding much more acute activity are cases of poisonings. In these cases primary care professionals need specific and comprehensive treatment management details immediately.

Information sources. Primary care professionals commonly consult textbooks or partner to price their information needs (Gorman and Helfand, 1995). Because that acute care situations, primary treatment professionals speak to poison control centers for certain treatment monitoring protocols. These resources are rapidly accessible and can provide summarized information. Primary treatment professionals perform not have the time during the patient"s visit to search online databases, back searching may be an option prior to providing patient follow-up.

Barriers to making use of the TEHIP databases. Primary treatment professionals show that the significant barriers the they confront in looking the TEHIP databases space time, access, training, and the user interface. As indicated above, patient visits are short in duration and require rapidly easily accessible information. Primary treatment professionals might not have immediate access to online databases in the clinic or private-practice office. Additionally, cultivate of primary care professionals has traditionally been based on searching MEDLINE. Therefore, these health experts are regularly unfamiliar with the content of the TEHIP databases or the navigating methods necessary to conduct a search.

Opportunities. Fads in the increased availability and usage of computers bode well because that the usage of all virtual databases as health professionals concerned rely much more heavily on computer resources for your information. Since primary treatment professionals space most acquainted with browsing MEDLINE, any kind of efforts towards standardizing the interfaces (i.e., do MEDLINE and also TEHIP database searching similar from the user interface) will boost the energy of the TEHIP databases come these health and wellness professionals. Any modifications or refinements make in the TEHIP databases have to be steady grounded in the realities of everyday practice, including issues of need, access, and also cost. Training should be concentrated on those databases of biggest clinical worth (e.g., TOXLINE and HSDB). There space many opportunities for training primary care professionals consisting of increased emphasis on occupational and also environmental health problems during skilled training and continuing education courses.

Occupational and also Environmental health and wellness Specialists

Information needs. Occupational and also environmental health professionals (e.g., physicians, nurses, nurse practitioners, doctor assistants, industrial hygienists, and safety officers) need comprehensive information, frequently on details exposures. Focus group entrants expressed a preference for making use of bibliographic databases to locate the primary literature rather than relying top top summarized info presented in textbooks, factual databases, or other tertiary sources.

Information sources. Specialists provided that they usage a number of databases to fulfill their info needs, including NIOSHTIC, ReproTox, and also some of the TEHIP databases, specifically TOXLINE, RTECS, and IRIS.

Barriers to utilizing the TEHIP databases. Specialists frequently work in scholastic health treatment centers, where access to the databases is available; however, they have actually indicated the they are still often baffled by the user interface to the TEHIP databases (particularly the straight searching interface) and are regularly not familiar with the range of information obtainable through the TEHIP enhance of databases.

Opportunities. Marketing the TEHIP databases to this team of health experts at occupational and environmental health and wellness conferences may be an especially useful. These health experts are potentially extensive users the the TEHIP databases and also indicated that hands-on training through using instance studies and real-life scenarios would certainly be beneficial in helping them to become an ext comfortable with searching the TEHIP databases. Initiatives to enhance the user-friendliness that the search user interface would additionally improve the utility of the databases because that these wellness professionals.

Emergency Medicine and Poison Control facility Personnel

Information needs. Health specialists working in poison control centers, in emergency rooms, and also on emergency response teams need rapid info on toxicity exposures. Lock are commonly working v exposures to family members products and need to be able to specifically analyze the brand surname of a toxic substance into information that will administer the ideal treatment protocol.

Information sources. Committed information sources have actually been arisen for use by poison manage centers. Databases, an especially POISINDEX® room used since they space searchable by brand name and provide links to comprehensive treatment protocols. Various other databases, including the TEHIP databases and also reference books, are supplied by poison control centers come provide added information.

Although some emergency clinical departments have actually in-house accessibility to the POISINDEX® database, countless emergency clinical personnel call poison manage centers to acquire toxicity information and also management recommendations. A 1991 study of emergency physicians in Utah discovered that 94 percent used poison manage centers as their details resource, 78 percent used toxicology textbooks, 34 percent consulted v a colleague, and 24 percent accessed an in-house POISINDEX® database (Caravati and McElwee, 1991).

Barriers to utilizing the TEHIP databases. Among the major barriers to utilizing the TEHIP databases because that emergency care is the the TEHIP databases execute not have the quick links in between brand names and detailed emergency treatment protocols. Therapy protocols in HSDB are noted from the POISINDEX® database and also are made accessible to HSDB with a reciprocal agreement between and Micromedex, Inc. (see thing 2).

Opportunities. There are methods for and also the American association of Poison control Centers to work together on refinements to the TEHIP databases that would certainly make these resources more useful for poison control centers and also for the larger health care community.

Health science Librarians and Faculty in ~ Health experienced Schools

Information needs. Faculty in health skilled schools (including nursing, pharmacy, dental, publicly health, and also medical schools) need a working expertise of the info resources obtainable in toxicology and also environmental health to incorporate info resources into case studies and other teaching tools. Librarians functioning in wellness science libraries and other academic institutions have actually a wide selection of information needs depending on the kind of info requested.

Information sources. Because they work in scholastic institutions, these health experts are likely to have accessibility to online and CD-ROM databases. Faculty might rely ~ above textbooks and also other recommendation materials, which space easily available in their offices, and on partner with specialized expertise, that are additionally readily available. Wellness science librarians use plenty of online and print info resources.

Barriers to utilizing the TEHIP databases. The complexities the the user interface to the TEHIP databases may deter part faculty members from experimenting the scope of the databases. Due to the fact that numerous databases save on computer toxicology and environmental wellness information, faculty members and health science librarians might be unaware the or unfamiliar through the certain databases in the TEHIP complement.

Opportunities. Faculty members would benefit from case studies that have been put together for your use and that encompass links or recommendations to the TEHIP databases and other information resources in this field. The case studies would be an especially valuable as teaching tools if lock were focused on details topics currently being handle in the curriculum (e.g., bear defects, cancer, and acute poisonings). Seminars in ~ health professional conferences might focus ~ above demonstrating the limit of this online sources by using instance studies. By making use of the national Network the Libraries of medicine to increase awareness, not just of this databases but also of the panoply of ecological health and also toxicology databases, would efficiently reach wellness science librarians.


As seen in the previous section, health specialists have varied needs because that toxicology and also environmental health information and face various barriers to fulfilling those info needs. The strengths that can carry to be affected by each other on this difficulty are significant. has actually the traditional strength of librarians and also libraries, which is equivalent information come the info need. Additionally, has actually state-of-the-art technical field of expertise in details organization and also retrieval with its extensive research and advance program.

The emphasis groups (Appendix C) and also the responses come the questionnaire (Appendix B) sponsored by the committee provide initial insights into the toxicology and environmental health information requirements of health and wellness professionals and also the use of the TEHIP databases by these individuals.5 with this input and also committee deliberations, the different nature that the 16 databases in the TEHIP regimen became more evident. The committee known that the databases are not equally helpful for the work-related of the various segments of the health experienced community. Although the committee realized the the current TEHIP enhance of databases is the result of both initiatives and also interagency agreements and that each database fills crucial information niche, the committee believes that the TEHIP program should set priorities the would enable efforts come be focused on those databases that satisfy the information needs the the greatest number of health professionals. This is particularly an important in light of the truth that the TEHIP program has experienced reduced capital levels from interagency agreements in recent years (Chapter 2).

Comparable to a service marketing strategy that necessitates an understanding of the details needs of current and also potential customers prior to designing and distributing the product, this prioritization that the TEHIP regime would first require a an ext in-depth analysis of the toxicology and environmental wellness information requirements of health professionals. This would incorporate an understanding of the paths of information seeking, the level of detail in the information needed, the species of details required, who searches because that information, and also the obstacles to retrieving information. The score of this user profile evaluation would it is in to match, as carefully as possible, the needs of health specialists with details TEHIP databases. Upon completion of the user analysis, TEHIP routine staff might not just prioritize your training and also outreach initiatives with an emphasis on those databases that space the most valuable to health and wellness professionals however could also prioritize the resources that are committed to the databases with the greatest utility for health and wellness professionals.

An in-depth evaluation of the user ar could be obtained from workshops, surveys, and focus groups. Additionally, as will be questioned in thing 7, one advisory committee come the TEHIP routine composed the potential users and also a liaison committee composed of to represent of various other federal government agencies involved in environmental health issues would make an important contributions in assisting in understanding the needs of the user communities.

The committee recommends the further expand its efforts to recognize the toxicology and environmental wellness information needs of health and wellness professionals and also the barriers they face in accessing that details by conducting a in-depth user file analysis. Additionally, the committee recommends that the outcomes from that analysis be offered to set priorities for subsequent initiatives of the TEHIP program.

It is essential to keep in mind the constraints of the focus groups and questionnaire. The committee did no attempt to achieve a random clinical sample for the distribution of the questionnaire. Rather, the questionnaire was spread both to experienced association members and via the Internet. Thus, the was not feasible to recognize the prices of response or come charecterize the nonresponders. Additionally, responding via the net requires some level of computer expertise. Since travel time and expenses were considerations in inviting focus group participants, many of the entrants were attracted from the mid-Atlantic, particularly the Washington, D.C. Urban area.
