מערכת "הרפואה"

"הרפואה", עיתונם של הרופאים בישראל, משקף את הפעילות הרפואית הקלינית בישראל. מירב ומיטב הרופאים שולחים מאמרים ל"הרפואה" והעיתון המופץ בקרב כל חברי ההסתדרות הרפואית בישראל, מהווה כרטיס ביקור עדכני של המחברים ואמצעי להעברת מידע בין הרופאים והחוקרים. הודות לכך, הגיע עיתון "הרפואה" בשנים האחרונות לרמה מקצועית גבוהה מאוד והדבר בא לידי ביטוי גם במלאכת העריכה הצרופה. כתיבת מאמר מדעי-רפואי היא אומנות לשמה. היא כוללת שלבים רבים, החל מגיבוש הרעיון המרכזי, דרך איסוף החומר, ניתוח הנתונים ועיבודם ועד לדרך הצגת הדברים בצורה מגובשת ובהירה ברמה מדעית הולמת. כתיבה לעיתון "הרפואה" מטילה על המחברים תוספת נכבדה של התייחסות לשפה העברית המהווה מיקטע נוסף במרקם הכולל של מעשה האומנות.

במאמרי הקודמים, ניסיתי להתריע על מספר נושאים הקשורים במצבה בהווה של הרפואה הפנימית, עם שימת דגש מיוחד על ההשלכות העתידיות על צורת הפעילות, גורלם של החולים ועתידו של הרופא הפנימי החוקר. נמצא, שהמחלקות ברפואה פנימית נתונות תחת לחץ יוצא דופן, אשר גדל והולך ובמצב של תת-תיקנון. מצבים אלו מובילים לריבוי טעויות, אי שביעות רצון של מאושפזים ובני משפחותיהם, טרוניות ותלונות ואף תביעות משפטיות. במקביל, עולה אי-שביעות הרצון של המתמחים, המלווה בנטישת המערכת תוך סיכון עתידה של המחלקה לרפואה פנימית.

במאמרי הנוכחי, אני רוצה לתאר את אופי ההתקבלויות במחלקה הפנימית ביום פעילות שיגרתי, המזכיר מחד-גיסא את הפעילות היומיומית השוטפת בחדר מיון ומאידך גיסא, משתווה להגדרה של "פיגוע המוני". הגדרה זו על פי מינוח צה"ל כוללת: אירוע שבו מספר הנפגעים או קצב הגעתם עולה על יכולת הצוות הרפואי הקיים לתת טיפול רפואי מיטבי לכל נפגע.

Hand-in-hand with the public's growing interest in health care, there has been an increasing demand for natural health products considered both safe and medically effective. But many such products have not been shown to meet efficacy and safety criteria and therefore can not be registered as pharmaceuticals. On the other hand, it is quite clear that some products do have pharmacological activity and are being used for therapeutic or preventive effects.

In Israel, the marketing rules for food or dietary supplements prevent their manufacturers from claiming medicinal/healing properties that the product might have, and allow only limited health statements. But great demand for these products has created massive publication attributing medicinal indications for products whose quality, efficacy and safety have neither been examined nor proven according to accepted medical criteria.

We review the regulation and supervision of natural health products in Israel and other developed countries and find a broad range of opinions about natural health products. They range from acceptance as conventional drugs reimbursable by the health insurance, as in Switzerland and Germany, to their status as dietary supplements requiring no significant authorization or supervision, as in the USA.

Analysis of the current situation in Israel and the western world would indicate that some natural health products do possess pharmacological activity and therefore manufacturers should be allowed to make limited claims for specified therapeutic properties. A stricter set of registration regulations are needed for proof of safety, efficacy and quality of these products, but more lenient than those for registering a pharmaceutical product.

350 patients attending 11 large out-patient clinics completed questionnaires evaluating attitudes to, and experience with complementary medicine. 129 (36%) respondents reported using complementary medicine. 14% of them used complementary medicine for the current medical problem for which they were attending the clinic.

Pain was the most common medical problem for which complementary medicine was used, followed by respiratory problems and cancer. Common therapeutic modalities used were acupuncture, homeopathy, nutrition and herbal medicine.

Women, the secular as opposed to the religious, and those with higher education were more apt to use complementary medicine. No differences were found in age, national origin, length of living in Israel, and diet (vegetarian, natural foods or regular diet) between those who used complementary medicine and those who did not. No relationship was found between the use of complementary medicine and perceived poor health status, locus of control, or satisfaction with the doctor-patient relationship.

Opinions of the National Health Insurance (NHI) Law held by primary care physicians were surveyed. A questionnaire was submitted (April-July 1997) to 930 primary care physicians employed by sick funds, including general practitioners, family physicians, pediatricians and internists. Response rate was 86%.

They supported the main components of the NHI law. It was considered desirable "to a great" or "very great extent" to allocate funds to sick funds based on age and number of members (76%), to require them to accept all applicants (72%), to designate a uniform basket of services (65%), to allow members to transfer freely between funds (63%), and to allow sick funds to sell supplemental insurance (59%). However, only 41% were satisfied with the implementation of the law.

Multivariate analysis showed that employment by Maccabi, Meuhedet, or Leumit sick funds had an independent effect on low satisfaction with the law as implemented, and on negative opinions about the uniform basket of services, the accepting of all applicants, and allocation of funding based on age and number of members. Those employed by the Maccabi and Meuhedet funds were in favor of allowing sick funds to sell supplemental insurance.

The findings of the study have implications for policy-makers interested in increasing support for national health reform by physicians. It is important to examine possibilities of developing direct channels of communication between national policy-makers and physicians, as well as institutionalizing mechanisms that involve physicians directly in formulation of national policy.

Familiarizing Medical Students with Hospital Social Worker's Role

Dept. of Social Work, Meir Hospital, Kfar Saba

Patient care in a general hospital is usually provided by a multi-professional team. Treatment is most effective when each professional understands the functions of the various other members of the team. Professional literature and research have highlighted differences in perception by social workers and physicians of the proper function of the medical social worker.

Our social work department has developed a teaching program for medical students to enhance their knowledge with regard to this issue. It is presented at a single-session group meeting of an hour and a half, with structured content and goals.

Israel Naval Medical Institute: 20 Years of Applied Research, and Future Goals 

Ran Arieli, Avi Shupak

The Israel Naval Medical Institute (INMI) is unique as a research center located in a naval base and having close inter-relations with naval underwater units. It is ideal for applied research, and for mutual exchange of needs and of ideas and instructions.

Factors making this institute so suitable for applied research include: direct personal communication with combat divers, professional naval divers, submariners, civilian recreational divers and professional civilian divers, as well as naval vessel crews prone to seasickness; hyperbaric oxygen therapy is administered in cooperation with a large neighboring hospital.

Close spatial and personal relations with an academic institution (the Technion, with its Faculties of Medicine, Biology and Biophysics) provide a basis for cooperative research which expands research capabilities, and allows access to extensive expertise, instrumentation and equipment. Close ties with physicians who served at the INMI in the past also bring them into this research community.

During their specialization, physicians may spend up to 6 months working with us on a research project. Undergraduate, graduate and post-graduate students may complete their research at our institute with the agreement of their parent academic institutions.

Much of the research can be released to the international community. However, some is classified, serves only internal needs or is not of public interest. The number of published papers has stabilized since 1991 at about 16 a year.

Studies of gas exchange and oxygen toxicity originate mainly in the Hyperbaric Research Unit, research on motion sickness in the Motion Sickness and Human Performance Laboratory, and work on hyperbaric and diving medicine in the Clinical Section of the INMI.

Clinical characteristics of 125 divers treated for decompression sickness (DCS) in the hyperbaric multiplace chambers of this Institute during 1992-1997 were analyzed retrospectively. In 62 (51%) the diagnosis was DCS Type I (joint pain or skin involvement) and in 60 (49%) DCS Type II (neurological, inner ear or pulmonary disease). Risk factors for the evolution of DCS were depth and duration of the dives involving accidents, violation of recommendations of the decompression tables, and repeated dives.

Results were available for 112 of the 125 patients. 54 of them (48%) recovered completely, and another 54 recovered partially; 4 did not respond to treatment. Inner ear DCS was less responsive to hyperbaric oxygen treatment (p=0.0001). There was significant improvement of neurological function in those with severe neurological injury (p=0.0001). Rapid diagnosis and transportation of divers with DCS to a hyperbaric chamber is of crucial importance.

Many physicians, civilian as well as in military, feel that some referrals of soldiers to civilian emergency departments are inappropriate and that soldiers should receive medical attention within their military units. We therefore evaluated referrals of soldiers to our emergency department.

707 referral letters from military physicians and the corresponding emergency room discharge letters were evaluated. Most soldiers were referred for mild trauma (45.0%) or miscellaneous diseases (52.9%); 22 (3.1%) were hospitalized.

It appears that some military physicians use the civilian hospital emergency department as a surrogate for an out-patient specialty clinic and for x-ray and laboratory services. This is in contrast to the designated functions of the emergency department which are to provide emergency and trauma services and to evaluate the need for hospitalization of referred patients.

The population of the Negev consists mainly of Jews and Bedouin, who have very different life styles. Patients of both ethnic groups use our emergency department exclusively, providing a unique opportunity to study comparative patient habits.

In gathering and processing the information we used Data Mining technology, which allows search for unique patterns in large data bases. We examined demographic data on some 64,000 emergency department visits during 1997-8, mostly medical and surgical cases, but not trauma cases. Many more were by Bedouin than Jews, and between the ages of 25 and 44, more by women than men. There were changes in trends in comparison with an arrival survey conducted some 11 years before.

The Internet is efficient in coping with the ever-increasing volume of medical knowledge. This and other functions have lead to its integration into daily medical practice. It is therefore imperative to disseminate its use among physicians, as some, unfamiliar with the personal computer (PC), may be reluctant to learn to use it. We therefore developed a course for training physicians in the basics of Internet use, consisting of 6 sessions of 2 hours each. It includes training in PC operation as well as in the main Internet functions. The topics are medicine-oriented, including Medline search, general info search, exploring medical sites and reading medical journals on-line.

41 physicians (8 groups of 4-6 each) with various specialties attended, of whom 38 completed a feedback questionnaire 4 weeks later. 79% reported using the Internet either at home or at their working place. The function used mostly was Medline Search (68%). Although 83% had not been familiar with the PC before, 96% stated that the course was clear and understandable and 99% expressed satisfaction with the quality of the teaching. Based on these results we recommend this course as a model for teaching physicians the use of the Internet.

The efficacy, safety and side-effects of treatment with losartan (Ocsaar) was studied for the first time in Israel in a large group of patients with mild to moderate hypertension in several community clinics. The 421 patients (51% men) aged 30-86 years (mean 58.6) received 50 mg of losartan daily, increased when necessary to 100 mg, and/or a second antihypertensive drug was given. After 4 weeks blood pressure was normalized in 344 and after 12 weeks in 363. Side-effects were minimal and treatment was effective in all age groups.

The Israeli health system has been undergoing major changes in recent years. Considerations of cost containment have led sick funds to open new out-of-hours services in the community to reduce visits to hospital emergency departments.

Referred and self-referred visits to our emergency department during a 1-month period were studied. Patients after trauma or whose visits resulted in hospitalization were excluded. Of the 505 encounters 56.3% were of women; the average age was 52.5±19.3 years (range 18-96). 57.4% visits were during working hours of primary care clinics ("working hours"), while the others were "out-of-hours" visits. Only 52.7% had a referral letter, 75% of them from the family physician. The quality of the handwriting in 46% was good, in 44% fair and the remaining 10% were illegible. A specific clinical question was asked in only 16% of the letters. A third of "working-hours" visits were self- referrals, rising to 64% in "out-of-hours" visits (p<0.001).

The most common diagnoses in discharge letters were: chest or abdominal pain, asthma, back pain, headache, nephrolithiasis and upper respiratory tract infection. The rate of self-referrals was relatively high throughout the day. Cost-containment efforts did not seem to eliminate self-referrals with "primary care" problems. The quality of referral letters should be improved both with regard to format and content.
