The telephone in primary care.

This paper presents a review of the use of the telephone in primary care medicine. The telephone is available to a large majority of United States citizens, a situation that is unusual in other countries. Between 15 and 20% of all primary medical contacts in the United States occur on the telephone. Approximately 40% of routine office telephone contacts are administrative in nature, the remainder involving direct requests for advice or treatment. After office hours, requests for immediate medical advice constitute almost all of the calls (for both daytime and after hours calls). Close to 70% of the medical calls are managed solely by use of telephone. Although the telephone is effectively used for medical consultation, teaching and survey purposes, it has been shown that health professionals are protocols or specific training tends to improve performance, but such programs are not a regular part of medical education.

The telephone survey in family practice.

Patient surveys can be useful methods of obtaining information for the purposes of improving health services, practice management, or research in family medicine. The telephone interview is an effective and economical method of undertaking such a survey. The advantages and disadvantages of the telephone survey method are briefly illustrated by a study conducted in the Family Practice Center at the University of North Carolina concerning patient perspectives on their after-hours medical encounters with physicians.

Differential expression of the globin genes in human leukemia K562(S) cells induced to differentiate by hemin or butyric acid.

Human leukemia K562(S) cells were induced to differentiate by 50 microM hemin or 1.4 mM butyric acid, and the types of hemoglobins synthesized were compared. In both cases, embryonal hemoglobins [Portland, Gower 1, Hb X, and fetal hemoglobin (Hb-F)] were detected. Butyric acid-treated K562(S) cells contained mostly Hb Gower 1 (zeta 2 epsilon 2) and a hemoglobin with the electrophoretic characteristics of Portland (gamma 2 zeta 2). For hemin-treated K562(S), the most abundant hemoglobin synthesized by Hb X (epsilon 2 gamma 2), and the second most abundant was Bart's (gamma 4). Traces of Gower 1 were observed in nontreated K562(S) cells. The kinetics of hemoglobin induction as a result of the two treatments differed; increased hemoglobin synthesis was detected after only 24 hr of hemin treatment, whereas 4 days were required in butyric acid-treated cells. Both hemin and butyric acid were able to induce their respective patterns of hemoglobin synthesis independent of the presence of serum in the K562(S) growth medium. Analysis of the globin chains in induced K562(S) cells induced to differentiate indicated that, with both inducers, adult alpha- but not beta-globin chains were present. Karyotype analysis of K562(S) cells revealed a nearly triploid chromosome complement with a modal number of 68 chromosomes. Three copies of chromosome 11 and four copies of chromosome 16 (coding for the beta-like and alpha-like globin genes, respectively) were present. A large marked chromosome, involving chromosome 7, and a Philadelphia chromosome were also seen. These data characterize the K562(S) subline and also indicate that hemin and butyric acid differ in their effects on the expression of embryonal globin genes.

Three hundred years of family health care: some perspectives.

Many medical texts have been produced in the past to help the ordinary individual and his family care for themselves, without resorting to the services of a physician. Five "home care" books were randomly selected for study from the many hundreds spanning a period of approximately 300 years, up to the early 20th century. It is likely that these books, which dealth with a whole range of problems including morality, religion, and lifestyle, had a significant impact on the attitudes of society, many of which persist to this day. The importance of environment and natural therapies stressed in these books has been reemphasized in recent years.

Patient participation in a medical education environment.

Family practice residency programs are specifically directed toward training primary care physicians to serve the interests of communities. This paper describes two methods of developing a feedback mechanism to increase the awareness of physicians in training to patients' health needs and desires. One method involves the development of a patient advisory group in the Family Practice Center at The University of North Carolina, and the other an ongoing telephone survey of patients who call after hours.

The office laboratory in family practice residency programs.

A survey of family practice residency programs explored several aspects of the educational and clinical work of the office laboratories in residency centers. Many residency laboratories were found to have limited equipment and undertook only a few of the common procedures. Only 56 percent of residency programs had identified a specific educator for laboratory teaching. Only 15 percent or programs had established a formal curriculum in laboratory medicine. Curricula were poorly developed in the areas of quality control, equipment purchase, laboratory design, and the training of laboratory personnel. Recommendations are made for improving residency laboratories resident education in laboratory medicine.

The beta major and beta minor globin nuclear transcripts of Friend erythroleukemia cells induced to differentiate in culture.

Friend erythroleukemia clone 745 cells were induced to differentiate by dimethyl sulfoxide (Me2SO) or by hemin treatment, and nuclear transcripts of the beta major and beta minor globin genes examined. The beta major and beta minor genomic sequences selectively labaeled in the nonhomologous part of the large intervening sequence 2 were hybridized to the nuclear RNA of Friend cells. The nuclear RNA of Me2SO-treated cells contained both beta major and beta minor nuclear transcripts, whereas hemin-treated cells contained only the beta minor transcripts. The beta minor nuclear transcripts were more abundant in the Me2SO-treated cells than in hemin-treated cells. Nuclear transcripts with the size of partially processed beta major globin mRNA precursors were also detected in the Me2SO-treated cells.

A life-cycle conference series; education for general practice.

An all around educational programme for general practice trainees involving a conference and seminar cirriculum was developed, based on a life-cycle concept. In addition to emphasizing the study of usual life stresses and crisee for individuals and families, the programme encouraged the contribution of resource people from many related medical disciplines and also from the non-health sciences. Detailed planning allowed the structuring of the conference over an academic year. Clearly defining the objectives for each meeting led to effective evaluation and enhanced the educational process.

The concept and measurement of continuity in primary care.

Continuity of care, a stated fundamental principle of family medicine, is reviewed in terms of its philosophy and definitions. A model of continuity in primary medical practice is proposed, consisting of five elements: the provider, consumer, encounter type, knowledge base, and environment of continuity. The elements are measurable, some more easily than others. There is need to define and operationalize the model more accurately in order to evaluate continuity in primary care medicine.

Continuity of care in a family practice residency program.

Continuity of care, one of the basic characteristics of family medicine, was studied over a 12-month period in a family practice residency program. Continuity was measured in three contact areas; office hours, after hours, and on the inpatient service. The intensity of continuity was defined at three levels, from encounters with the personal physician to those with physicians on other medical teams. Continuity was further assessed in relation to family encounters. Third year residents averaged 83 percent continuity with their individual patients and 70 percent with their assigned families. Residents from other years were noted to have lower levels of continuity. Similar figures were noted for family practice inpatients. Continuity of care in private practice occurs in about 80 percent of patient encounters and it seems reasonable and feasible to expect residency training programs to come close to this figure.

The after-hours call in family practice.

Patient care after hours continues to be an important part of the work of family physicians, in spite of the trend towards increasing Emergency Room utilization. In this paper the literature concerning after-hours care in family practice is reviewed in terms of definition, demography, utilization, morbidity, and patient stereotypes. In the Family Practice Residency Program of the University of North Carolina, 4,760 after-hours calls were recorded over two years by residents and faculty physicians. Seventy-two percent of the calls were handled purely on the telephone with little variation for patient age groups. The overall call rate was 474 calls per 1,000 patients per year. Fever and skin wounds were the most frequent symptoms recorded and respiratory tract infections, minor trauma, and anxiety were the commonest diagnoses. Thirteen percent of the contacts engendered anger or frustration in the physician. A survey of patients calling after hours demonstrated a lack of congruence between physician and patient concerning the main reason for the call in over 30 percent of contacts.
