Introduction
Informal medical consultation, in contrast to formal medical consultation, is characterized by the provision of undocumented medical advice. This includes any medical consultation or treatment provided to colleagues, family members or friends. Numerous surveys and editorials have described the intervention of physicians in the health care of family members [
1]. The practice has persisted over the years, despite the inherent problems and the recommendations by such publications and by medical associations against it. In addition to family members, friends and persons of other relations request and receive informal medical consultation. Described as “corridor”, “hallway” or “curbside” consultation, such practice has been described in diverse medical disciplines [
2,
3] and geographical regions [
1,
4] Self-care and self-prescribing by physicians have also been widely described [
5‐
10].
Israel has a national health insurance system, in which all the residents are insured by one of four health maintenance organizations (HMOs). Family physician visits are at no cost. Small co-payments are charged for visits with specialists, though low socioeconomic status exempts also from these costs. During 2016, nearly 83% of Israeli households purchased complementary health insurance from their HMOs [
11]. The benefits of such include subsidies for second opinion consultations and scheduling appointments with shorter waiting periods.
In a survey study conducted in Israel over 20 years ago, 82% of hospital physicians reported having been asked to provide “hallway medicine”; of them, 91% agreed [
12]. However, no position paper has been issued in Israel over the last two decades to guide physicians in dealing with this phenomenon. We conducted a survey among family physicians in southern Israel, to assess the current prevalence and characteristics of informal medical consulting, the reasons physicians provide it, and their attitudes toward it.
Methods
This multicenter survey study is based on questions written by the researchers. The study population is primary care physicians (family physicians, general physicians and residents) who are employed in southern Israel. In total, 595 physicians were eligible to participate, from the two largest HMOs in Israel: 356 from Clalit Healthcare Services and 239 from Maccabi Health Services.
The questionnaire was designed to access information regarding the prevalence, reasons, means of practice and attitudes to informal medicine consultation among primary care physicians. A pilot test was performed on the initial questionnaire, among 10 participants. Following their comments, the questionnaire was revised to the final version (see Additional file
1). The questionnaire comprised 15 questions on practice and attitudes; each with 2–6 possible responses. One question asked the extent that the physicians consider each of 5 factors when approached for informal advice; the responses were on a 5-point Likert scale. Ten questions accessed information on demographics and professional experience.
The questionnaires were sent by a link to all the email addresses of the primary care physicians affiliated with Maccabi Healthcare Services and Clalit Health Services in the southern district of Israel. A request was included on the questionnaires, that physicians should not fill the questionnaire more than once. Three reminders were sent, at intervals of 3–4 weeks.
Statistical analysis
Statistical analysis was performed using the IBM SPSS version 25. Data were reported as means and standard deviations for continuous variables, and as percentages for categorical variables. We used the Student’s t-test to determine statistically significant differences in continuous variables that were normally distributed. For continuous variables that were not normally distributed or ordinal variables, we used the Mann-Whitney test or Kruskal–Wallis test, as appropriate. The Chi-square test and Fisher’s test were used to compare categorical variables. All p-values were two-sided and statistical significance was set at P ≤ 0.05.
The protocol was approved by the institutional review board of Maccabi Healthcare Services and the ethical committees of Maccabi and Clalit Health Services.
Discussion
This survey study revealed great dissonance among primary care physicians, between their behavior and their attitudes, in regard to informal medical consulting. On one hand, an overwhelming proportion reported involvement in such consulting, including more than half who reported frequent rates. Further, almost half reported that they usually or never refuse a request from family or friends for informal consulting. On the other hand, more than half the participants in the survey stated feeling discomfort or regret after providing informal consulting. More specific analysis of the data reveals that some respondents may resolve the dissonance integral to their provision of informal medical consulting. Specifically, those who reported more frequently providing informal consulting, expressed greater support of such, and their feelings following informal consultations were more positive than were those who less frequently provided such consultations.
The high proportion of physicians reporting informal consulting concurs with other studies, most of which focused on consulting to family members [
1]. Nonetheless, the report by 30% of family physicians in the current survey, of providing informal consulting on a daily basis is remarkable. A particularly high prevalence of informal medicine in Israel may be related to cultural factors. Along this line, the practice in Israel of informal payments for health care has been explained in the context of a specific type of political culture, called “alternative politics” [
13]. This is characterized by a “do-it-yourself” approach, which bypasses formal rules and relies on personal and reciprocal relations. The scope of this approach is broad, and may contribute to understanding the atmosphere that makes it difficult for physicians to refuse requests for informal consulting [
12].
The negative attitude toward informal medical consulting expressed by the respondents of the current survey corroborates other publications [
1]. Problems related to the lack in medical documentation, objectivity, and professionalism were the main disadvantages cited for informal medical consultation, concurring with the literature [
1].
Only 2% of the respondents presumed that financial savings was the motivation for informal consulting. This may reflect a pervasive impact of the national health insurance system in Israel, despite the heavy reliance of the health care system on private financing [
11]. In contrast, among 41 studies, financial savings was cited as a main reason for the intervention of physicians in the health care of family members [
1].
In the current investigation of informal consultation, the high use reported of electronic mail and phone messages, including WhatsApp Messenger, is in agreement with the currently high use of these means of communication in formal medical consultation. WhatsApp Messenger has become a common telemedicine tool in conventional, as well as in informal medicine [
14]. In a study conducted among primary care physicians in Switzerland, 82% reported communicating with their patients by email [
15]. The authors emphasized confidentiality issues as a prime disadvantage to such.
Ninety-five percent of our respondents reported requesting informal consultation from other physicians for their personal health issues. This corroborates the documentations of this phenomenon around the world, as mentioned above. Notably, a recently published cross-sectional study showed that two-thirds of hospital-based physicians in Israel do not have a regular personal physician [
16].
Almost two-thirds of the respondents to our survey answered that a position paper on informal medical consulting could be beneficial. The proportion holding this attitude was particularly high among physicians who had more negative feelings after providing informal consultation and among those who reported receiving more than one daily request for informal consulting. The seventh edition of the American College of Physicians Ethics Manual, issued in 2019, [
17] expanded the topic of informal medical consulting, as well as the topics on electronic communication and telemedicine ethics. Accordingly, physicians are encouraged to avoid treating themselves and family members except in emergency situations. Among the reasons cited earlier by the American Medical Association for such recommendation are difficulties in objectivity, in accessing full information and in professionalism that arise in the context of informal medical consulting [
18]. Our study considered informal medicine in a broader sense than in the American College of Physicians Ethics Manual. Remarkably, 95% of our responders reported providing informal medicine in the form of treatment and health care management, and not only clarification and interpretation of clinical information. More detailed guidelines may be beneficial to physicians, with a broader scope in regard to the nature of informal consulting, and including consulting of persons who are not family members.
No differences were found between specialists and residents in the responses to any of the items of the survey. This contrasts with the findings of a qualitative study conducted in the Netherlands, which showed more difficulties among junior than senior physicians in dealing with requests for informal consulting [
19].
A main limitation of this survey study is selection bias, arising from the possibility that the respondents to the survey may not have been representative of the family physicians in the region examined. The questionnaire was kept short, so as to encourage respondents to fill it completely. Accordingly, very few responses were left blank. Nonetheless, the brief and structured questionnaire is limited by the information it was able to assess, compared to a more in-depth questionnaire or an interview.
