Occupational history collection by third-year medical students during internal medicine and surgery inpatient clerkships

Environmental Hazards and Risk Assessment in Primary Care

Environmental health is often considered the oldest public health practice; yet, in many respects, particularly in relation to chemical exposure and impact, we know very little about the span of consequences. According to the World Health Organization, environmental hazards are responsible for 23% of the total burden of disease worldwide. Environmental and occupational diseases frequently manifest as common medical problems or have nonspecific symptoms; yet consideration of environmental factors rarely enters into the clinician’s history taking or diagnosis.

Improving the quality of industry and occupation data at a central cancer registry

BACKGROUND

Central cancer registries are required to collect industry and occupation (I/O) information when available, but the data reported are often incomplete.

METHODS

We audited the completeness of I/O data in the New Hampshire State Cancer Registry (NHSCR) database for diagnosis year 2005, and reviewed medical records for a convenience sample of 474 of these cases. We compared I/O data quality before and after a statewide registrar training session on occupationally related cancers.

RESULTS

The original 2005 data contained both I/O data in 11.5% of cases, and lacked any I/O data in 74.5%. Corresponding figures for cases selected for audit were 15.2% and 77.2%, which improved to 54.2% and 11.8% after medical record review. After registrar training, 47% of reports contained both I/O data, and only 14.4% of cases lacked any I/O data.

CONCLUSIONS

Statewide training to highlight the importance of I/O data is an effective method to improve I/O data quality.

Practice Patterns of Pulmonologists and Family Physicians for Occupational Asthma

BACKGROUND

The longer the duration of symptoms of occupational asthma (OA) before diagnosis, the poorer the outcome. Physicians can play a key role in the early recognition of occupational lung diseases (OLDs), including OA. Our objective was to document and compare the practice patterns, barriers, and needs for early diagnosis of OA among pulmonologists and family physicians.

METHODS

Based on information from the literature and interviews with pulmonologists and family physicians, a survey was developed to obtain information on practice patterns. The survey was sent to all pulmonologists and a random sample of 600 family physicians in Ontario.

RESULTS

Eight percent of pulmonologists and 7% of family physicians report seeing >20 patients a year with OLD. The majority report taking a workplace exposure history. The most commonly stated barrier to obtaining a workplace exposure history was time constraints. Main reasons for referral to specialists for diagnosis include personal lack of expertise, testing facilities, and knowledge about workers' compensation, while lack of timely access to specialists is a barrier for referral. While most physicians identified a need for further education, those who did not identify a need for further occupational respiratory education cited low volume of patients, access to specialists, and time constraints as reasons for not wanting further education.

CONCLUSIONS

Opportunities are identified to improve health services delivery and educational initiatives for OA, with approaches tailored to each particular physician group.

Dermatologist and family practitioner practice patterns for occupational contact dermatitis

Medical practitioners have a role in the recognition of occupational contact dermatitis. The longer the duration of symptoms before diagnosis, the poorer the outcome. Our objective was to understand practice patterns, barriers and needs for early diagnosis of occupational contact dermatitis. A survey to obtain information on practice patterns was developed based on the literature and interviews with dermatologists and family practitioners. The survey was sent to all dermatologists and a random sample of 600 family practitioners in Ontario. Fifty-seven per cent of dermatologists and 9% of family practitioners report seeing more than 20 patients per year with occupational contact dermatitis. The majority of practitioners report taking a workplace exposure history. Barriers to taking a workplace exposure history include time constraints and lack of knowledge. Reasons for referral to specialists include a lack of expertise, testing facilities and knowledge about workers' compensation, time constraints and inadequate reimbursement, whereas lack of access to specialists is a barrier for referral. Although most practitioners identify a need for further education, a low volume of patients and time constraints are key barriers to continuing education. Opportunities are identified to improve educational initiatives and health services delivery for occupational contact dermatitis, tailored to each practitioner group.

Quality of occupational history assessments in working age adults with newly diagnosed asthma

BACKGROUND

Approximately 10 to 15% of new-onset asthma in adults is attributable to occupational exposure. The occupational history is the most important instrument in the diagnosis of occupational asthma (OA).

STUDY OBJECTIVES

To assess the quality of occupational histories obtained by health-care providers and to measure the prevalence of clinician-diagnosed OA in a population at elevated risk for OA.

SETTING

An academic US Department of Veteran Affairs medical center.

STUDY POPULATION

One hundred ninety-seven adults (age range, 18 to 55 years) with newly diagnosed asthma who had completed pulmonary function testing (PFT) and a structured respiratory health questionnaire.

MEASUREMENTS

We conducted a structured retrospective comparison of occupational respiratory health history documented by clinicians with data documented by patients on a structured questionnaire. We analyzed PFT results to assess physiologic impairment. We also conducted a structured examination of the actions taken by health-care providers based on their occupational history assessments.

RESULTS

Patient self-reports of respiratory exposures and symptoms were common. A job title was documented by one or more clinicians in 75% of patient medical records. Additional occupational history data were charted much less frequently. A diagnosis of OA was made in only 2% of patients. Clinical action to address OA was documented for only one patient.

CONCLUSIONS

Clinicians who manage adults with newly diagnosed asthma take incomplete occupational histories. We detected discordance between the occupational exposure histories documented by patients and those charted by clinicians. OA may go unrecognized and possibly undermanaged by clinicians.

Occupational medical history taking: how are today's physicians doing? A cross-sectional investigation of the frequency of occupational history taking by physicians in a major US teaching center

Occupational illness plays a prominent role in the health of society, yet physicians frequently neglect occupational history-taking both in clinical practice and in medical education. This study sought to examine the trends as well as related factors that influence the taking of occupationally related histories. A total of 2050 charts were reviewed for occupational information as well as several patient demographics. Physicians obtained gender and age histories in approximately 99% of their patients; however; they only completed an occupational history in 27.8%. Characteristics such as smoking, male gender, family cancer history, middle age, and medical (vs. surgical) admission were all correlated with obtaining an occupational history. Physicians continue to do a poor job of occupational history-taking and medical education must correct the situation.

Medical students' abilities to take an occupational history: use of the WHACS mnemonic

This study examined medical students' use of the WHACS mnemonic during an occupational history objective structured clinical examination station. Students' performance on the 10 content-specific station items was calculated. Factor analysis of the items was conducted, and student demographic and academic characteristics associated with performance on the station were examined. A total of 205 students completed the station. The mean number of correct responses was 5 (SD, 1.6). Students performed well on some items and less well on others. Factor analysis supported the WHACS framework. There were no significant associations with student demographic or academic characteristics. Students were aware of the particular features of an occupational history but were deficient in other areas; this awareness was not related to demographic or academic characteristics. The WHACS mnemonic could be an effective tool to teach occupational history-taking skills.
