Abdominal pain in the primary care setting.

The characteristics of and final diagnoses for patients presenting with abdominal pain were investigated. This retrospective study examined 556 charts of patients 18 years of age and older who presented over a two-year period to three family practice offices. The charts were abstracted for demographic factors, symptoms, physical findings, laboratory data, final diagnosis, and number of visits for abdominal pain. The final diagnosis was documented by radiologic, laboratory, surgical, or pathologic specimen confirmation except for the following diagnoses: acute gastroenteritis, pelvic inflammatory disease, irritable bowel syndrome, and abdominal pain, etiology undetermined. No cause for the abdominal pain was found for approximately one half of the cases. Most patients were female even when gynecologic problems were excluded. Nine percent of abdominal pain patients were admitted to the hospital for evaluation or surgery. An average of 1.8 tests were ordered per patient. Almost one half of the patients were seen only once for the problem. The results suggest that a large percentage of the patients who present with abdominal pain have a self-limited illness for which no definitive diagnosis is found.

CTL and serologically defined antigens of B2m,H-3 region.

The antigens of the B2m,H-3 region of 13 chromosome 2 congenic strains and seven inbred strains have been studied by using CML and serologic techniques. Nine patterns of cross-reactivity have been defined by CML assays. These results are in agreement with an extend previously described cross-reactivity studies. The reactivities of three monoclonal antibodies previously thought to be reacting with B2M-B are shown to differ: Ly-m11 and J-5 react with cells of strain B10-pa,at and clone 23 does not. Two H-3 region loci are hypothesized on the basis of CML and serologic activity: B2m and H-3. The CTL responses to the B2M antigens are H-2K restricted; the CTL responses to H-3 antigens are H-2D restricted. The restriction of the response to the H-3 antigen requires effector-target identity of the H-2D molecule but not the B2M molecule of the class I antigen. These loci have been separated by recombination from H-42 in the production of the congenic strain B10.FS-a. A gene order of B2m, H-3, H-42 is suggested.

Computerized medical records in family medicine journals, 1981-1990: diffusion of an innovation.

This study examined whether references to computerized medical records in family medicine journals had increased over the past decade as an example of diffusion of innovations. The abstract and methods sections of articles in Family Medicine, the Journal of Family Practice, and the Journal of the American Board of Family Practice were reviewed from 1981 to 1990 for explicit references to computerized medical records. The proportion of articles citing computerized medical records did not significantly increase overall or in any one journal during this time. Articles referenced computerized medical records with regard to sample selection for research studies (54%), description of computerized medical record systems (26%), and generation of health maintenance reminders (4%). These results are discussed in the context of family medicine literature and in terms of factors that typically impede the diffusion of innovations.

Maintenance of clinical skills: a study of full-time physician teachers.

The ways in which full-time physician teachers of family medicine maintain their clinical skills were examined. A questionnaire survey of 500 randomly sampled physician teachers was conducted to examine their practice profile, both ambulatory and inpatient, and opinions as to the value of various activities in maintaining their clinical skills. Overall response rate was 84.4%, but only the responses of full-time teachers (69.6%) were used. Teachers spend 2.4 half days per week providing direct patient care and 3.1 half days per week supervising residents. Approximately 90% attend on an inpatient family medicine service, while about 60% admit and manage patients by themselves. A minimum of 2.3 half days per week of providing direct patient care was felt to be necessary to maintain clinical skills. Direct patient care was felt to be the single most important activity in maintaining clinical skills. While statistical differences among residency types existed, the faculty of the various types of residency programs had very similar practice profiles and opinions as to the maintenance of their clinical skills.
