Chapter 3. Diagnoses, Selected Illnesses and Conditions of Patients

  • Chapter 3 is also available as an individual Adobe Portable Document (PDF, 38.0 KB, 23pgs)

This chapter provides data describing the magnitude, distribution, and major demographic characteristics of illnesses and health conditions seen by the NYS Occupational Health Clinic Network (OHCN). Patients are presented by the first time a diagnosis is made. These diagnoses may change with subsequent visits due to further testing and presentation of symptoms. In order to present the patient load of some of these conditions, data is occasionally presented by number of visits per year. Patients seen in the NYS OHCN may have underlying conditions such as high cholesterol that are diagnosed through health screenings at workplaces or as part of the patient examination. Therefore, other health conditions that may not be directly related to the primary diagnosis of concern are often diagnosed and recorded in the patient database. However, due to differences in operations between the Clinics, these data are not always included in the patient database and do not necessarily provide an accurate indication of co-morbid and underlying conditions.

Disease categories were classified utilizing the International Classification of Diseases Ninth Revision (ICD-9-CM) main categories:1

  • 001-139: Infectious and parasitic diseases;
  • 140-239: Neoplasms;
  • 240-279: Endocrine, nutritional, and metabolic diseases, and immunity disorders;
  • 290-319: Mental disorders;
  • 320-389: Diseases of the nervous system and sense organs;
  • 460-519: Diseases of the respiratory system;
  • 520-579: Diseases of the digestive system;
  • 680-709: Diseases of the skin and subcutaneous tissue;
  • 710-739: Diseases of the musculoskeletal system and connective tissue;
  • 780-799: Symptoms, signs, and ill-defined conditions;
  • 800-999: Injury and poisoning; and
  • V01-V84: Supplementary classification of factors influencing contact with health services.

Because of the small number of patients seen, the following categories were combined into a group classified as "other":

  • 280-289: Diseases of the blood and blood-forming organs;
  • 580-629: Diseases of the genitourinary system;
  • 630-677: Complications of pregnancy, childbirth, and the puerperium;
  • 740-759: Congenital anomalies; and
  • 760-779: Certain conditions originating in or during the perinatal period.

Use of these categories does not always accurately reflect the types of diseases experienced by the NYS OHCN patients. For example, repetitive stress disorders are categorized under both "Diseases of the nervous system and sense organs" and "Diseases of the musculoskeletal system and connective tissue".

Of the malignant skin neoplasms diagnosed, 55% were work-related. These occurred primarily among those working in the agricultural or logging industry (93%). Females accounted for 43% of this group (data not shown).

Of those patients not related to the WTC disaster, 390 (43%) were work-related conditions, of which 103 were diagnoses of dysthymic disorder (ICD-9-CM code 300.4) which includes anxiety depression and reactive depression; 76 were depressive disorders (ICD-9-CM code 311) and 41 were posttraumatic stress syndrome (ICD-9-CM code 309.81).

The mental disorders not related to the WTC disaster were almost evenly divided between males (51%) and females (49%). The majority of these diagnoses were among residents of NYS outside of NYC (90%) and were White (84%) (data not shown). A much higher percent of WTC-related patients were male (74%) compared to the non-WTC patients (51%). A large percent of the WTC patients (70%) were residents of NYC (data not shown). The NYS OHCN has provided care to many of the workers and area residents involved in this tragedy - emphasizing that the effects of this tragedy are far-reaching in both geography and time.

<Work-related Asthma

Work-related asthma diagnoses (ICD-9-CM Code 493) that Center (WTC) Status were not associated with the WTC disaster were relatively equally divided between males (48%) and females (51%); three-quarters of the work-related asthma diagnoses associated with WTC exposures occurred among males (76%). Non-WTC related diagnoses occurred among those primarily from NYS outside of NYC (72%) and among those who were White (78%); WTC-related diagnoses occurred primarily among those from NYC (63%) and among those who were White (64%) (data not shown).
