Changes in the Management of Common Bile Duct Stones: 1980 to Date

OBJECTIVE

To compare the results of treating patients with common bile duct (CBD) stones by endoscopic sphincterotomy (ES), surgical exploration, or a combination of ES and surgical CBD exploration (the rendezvous technique).

METHODS

A narrative review of the literature.

SUMMARY OF DATA

Before 1990, 17 cohort studies indicated that ES cleared CBD stones in 92.0% of patients, with a mortality rate of 1.5%. Surgery removed CBD stones in 90.2% of patients, with a 2.1% mortality rate. A single randomized controlled trial in 1987 showed that ES removed CBD stones in 91% of 55 patients, with a 3.6% mortality rate and a 27% complication rate, whereas surgical CBD exploration removed CBD stones in 92%, with a 1.8% mortality rate and a 22% complication rate. Since 1991, 26 randomized controlled trials have shown that laparoscopic-ES rendezvous is as effective as ES alone and laparoscopic surgery alone but is associated with fewer complications, a reduced need for additional procedures, and a shorter hospital stay.

CONCLUSIONS

A laparoscopic-ES rendezvous appears to be the optimal approach to the treatment of CBD stones in younger and fit patients. The choice between ES alone and laparoscopic-ES rendezvous in older or high-risk patients remains uncertain.

Trust in public health policy in the time of the COVID-19 epidemic in Israel

The government of Israel provides universal health care through four health care organizations ("sick funds") that enjoy general public trust. In hindsight, the response of the government to the COVID-19 epidemic seems reasonable. In the first year of the epidemic, tests and vaccines were developed and other measures were taken, including social distancing, focusing on risk factors for infection and disease severity, and improving treatment. The COVID-19 mortality rate between January 2000 and June 2021 was around 750 per million inhabitants, well below the OECD average of 1300. Still, although the control measures were largely well received, the media and an ad hoc non-governmental Emergency Council for the coronavirus crisis in Israel criticized the government's response to the epidemic thereby contributing to a decline in public trust in government policy. This commentary provides an overview of the importance of trust in medical institutions and the difficulties of evaluating healthcare decisions in an attempt to justify three conclusions. First, when physicians and self-appointed experts publicly disapprove of a government policy, they should consider the trade-off between improving care and undermining public trust. Second, when evaluating a medical decision, experts should not ask, "Would I have acted differently?" but rather, "Was the decision under review completely unreasonable?" Thirdly, criticism is certainly worth listening to. However, I believe that by calling for organized resistance against the government, the publicly announced establishment of the Emergency Council for the Corona crisis blatantly crossed the line between constructive criticism and destructive mistrust.

Estimates of the lead time in screening for bladder cancer

Some studies have suggested a survival benefit from early treatment of bladder cancer (BC). This benefit may be due in part to a "lead-time" bias (LT), i.e., the time interval between the detection of BC in asymptomatic individuals and the development of symptoms ("backward prolongation of survival"). To estimate the LT of BC, it was assumed that LT corresponds to the ratio between the prevalence of pre-symptomatic BC and the incidence of symptomatic BC. Data on the prevalence of pre-symptomatic BC were derived from published screening studies. Data on the annual incidence of symptomatic BC at the age and gender of the study populations were derived from national registries in the countries in the years in which the screening studies were conducted. The ratios of the prevalence of presymptomatic BC to the incidence of symptomatic BC ranged from 3.3 to 12.1 years when derived from screening for microhematuria, and from 1.8 to 5.3 years when derived from screening for urine cytology and cell markers. The estimates of the LT of BC derived from the ratios between its prevalence in asymptomatic persons and its incidence in the corresponding population were consistent with those previously reported in retrospective and prospective cohort studies. Since these estimates may account for the survival benefit from early treatment of BC, the gain of screening for BC remains uncertain and should be confirmed by controlled randomized trials.

Asymptomatic Microscopic Hematuria in Inpatient Nonsurgical Adults

OBJECTIVES

This study sought to determine the proportion of nonsurgical inpatients with asymptomatic microscopic hematuria (AMH) who qualified for urologic investigation according to consensus guidelines.

METHODS

The study population included all patients acutely admitted to the internal medicine departments of Israeli regional hospitals between 2014 and 2017.

RESULTS

Of 29,086 consecutive admissions, 10,116 (34.8%) underwent dipstick urinalysis and 8,389 (28.8%) underwent reflex microscopic urinalysis. After the exclusion of patients with a urethral catheter or a positive urine culture, 2,206 had 3 or more RBCs per high-power field, and as many as 2,052 (7.1% of the entire cohort and 24.4% of all patients undergoing microscopic urinalysis) met the criteria for a urologic workup.

CONCLUSIONS

We conclude that according to the consensus guidelines, an unreasonably high proportion of hospitalized nonsurgical patients would be referred for a urologic workup of uncertain clinical utility because of an incidental AMH finding.

The presence of a urinary catheter is an important predictor of in-hospital mortality in internal medicine patients

RATIONALE AND OBJECTIVE

Mortality rates are used to assess the quality of hospital care after appropriate adjustment for case-mix. Urinary catheters are frequent in hospitalized adults and might be a marker of patient frailty and illness severity. However, we know of no attempts to estimate the predictive value of indwelling catheters for specific patient outcomes. The objective of the present study was to (a) identify the variables associated with the presence of a urinary catheter and (b) determine whether it predicts in-hospital mortality after adjustment for these variables.

METHODS

The study population included all acutely admitted adult patients in 2020 (exploratory cohort) and January-October 2021 (validation cohort) to internal medicine, cardiology and intensive care departments at the Laniado Hospital, a regional hospital with 400 beds in Israel. There were no exclusion criteria. The predictor variables were the presence of a urinary catheter on admission, age, gender, comorbidities and admission laboratory test results. We used bivariate and multivariate logistic regression to test the associations between the presence of a urinary catheter and mortality after adjustment for the remaining independent variables on admission.

RESULTS

The presence of a urinary catheter was associated with other independent variables. In 2020, the odds of in-hospital mortality in patients with a urinary catheter before and after adjustment for the remaining predictors were 14.3 (11.6-17.7) and 6.05 (4.78-7.65), respectively. Adding the presence of a urinary catheter to the prediction logistic regression model increased its c-statistic from 0.887 (0.880-0.894) to 0.907 (0.901-0.913). The results of the validation cohort reduplicated those of the exploratory cohort.

CONCLUSIONS

The presence of a urinary catheter on admission is an important and independent predictor of in-hospital mortality in acutely hospitalized adults in internal medicine departments.

Stop routine microscopic urinalysis in hospitalized patients with dipstick abnormalities?

BACKGROUND

Restricting the performance of microscopic urinalyses only to patients in whom it was specifically requested has been shown to reduce their number in laboratories servicing both inpatients and outpatients.

OBJECTIVE

To determine the effect of such restriction solely in in-patients in a 400-bed regional hospital.

METHODS

In 2017, we discontinued routine ('reflex') microscopic urinalysis for all positive dipstick results, and restricted such testing to in-patients in whom it was specifically requested by a doctor. We compared the numbers of patients in three internal medicine departments who had a urinalysis over 2-year periods before and after 2017, and reviewed doctors' complaints.

RESULTS

Before 2017, more than 80% of all dipstick tested samples had one or more abnormalities that led to a microscopic examination. Discontinuation of reflex microscopy reduced microscopic urinalysis to less than 10% of all patients with dipsticks on admission. Requests for repeat urinalysis decreased from 4.3% to 2.5% and there were no complaints after the change in policy.

CONCLUSIONS

Discontinuation of a 'reflex' microscopic urinalysis in patients with abnormal dipstick results did not increase repeat urine testing. Doctors apparently felt that the microscopic urinalysis does not have clinical utility in the vast majority of hospitalized adult patients.

Quality Assurance of Undergraduate Medical Education in Israel by Continuous Monitoring and Prioritization of the Accreditation Standards

External accreditation reviews of undergraduate medical curricula play an important role in their quality assurance. However, these reviews occur only at 4-10-year intervals and are not optimal for the immediate identification of problems related to teaching. Therefore, the Standards of Medical Education in Israel require medical schools to engage in continuous, ongoing monitoring of their teaching programs for compliance with accreditation standards. In this paper, we propose the following: (1) this monitoring be assigned to independent medical education units (MEUs), rather than to an infrastructure of the dean's office, and such MEUs to be part of the school governance and draw their authority from university institutions; and (2) the differences in the importance of the accreditation standards be addressed by discerning between the "most important" standards that have been shown to improve student well-being and/or patient health outcomes; "important" standards associated with student learning and/or performance; "possibly important" standards with face validity or conflicting evidence for validity; and "least important" standards that may lead to undesirable consequences. According to this proposal, MEUs will evolve into entities dedicated to ongoing monitoring of the education program for compliance with accreditation standards, with an authority to implement interventions. Hopefully, this will provide MEUs and faculty with the common purpose of meeting accreditation requirements, and an agreed-upon prioritization of accreditation standards will improve their communication and recommendations to faculty.

Parameters of the complete blood count predict in hospital mortality

INTRODUCTION

Mortality rates are used to evaluate the quality of hospital care after adjusting for disease severity and, commonly also, for age, comorbidity, and laboratory data with only few parameters of the complete blood count (CBC).

OBJECTIVE

To identify the parameters of the CBC that predict independently in-hospital mortality of acutely admitted patients.

POPULATION

All patients were admitted to internal medicine, cardiology, and intensive care departments at the Laniado Hospital in Israel in 2018 and 2019.

VARIABLES

Independent variables were patients' age, sex, and parameters of the CBC. The outcome variable was in-hospital mortality.

ANALYSIS

Logistic regression. In 2018, we identified the variables that were associated with in-hospital mortality and validated this association in the 2019 cohort.

RESULTS

In the validation cohort, a model consisting of nine parameters that are commonly available in modern analyzers had a c-statistics (area under the receiver operator curve) of 0.86 and a 10%-90% risk gradient of 0%-21.4%. After including the proportions of large unstained cells, hypochromic, and macrocytic red cells, the c-statistic increased to 0.89, and the risk gradient to 0.1%-29.5%.

CONCLUSION

The commonly available parameters of the CBC predict in-hospital mortality. Addition of the proportions of hypochromic red cells, macrocytic red cells, and large unstained cells may improve the predictive value of the CBC.

Teaching Shared Decision Making to Undergraduate Medical Students

Despite the wide endorsement of shared decision making (SDM), its integration into clinical practice has been slow. In this paper, we suggest that this integration may be promoted by teaching SDM not only to residents and practicing physicians, but also to undergraduate medical students. The proposed teaching approach assumes that SDM requires effective doctor-patient communication; that such communication requires empathy; and that the doctor's empathy requires an ability to identify the patient's concerns. Therefore, we suggest shifting the focus of teaching SDM from how to convey health-related information to patients, to how to gain an insight into their concerns. In addition, we suggest subdividing SDM training into smaller, sequentially taught units, in order to help learners to elucidate the patient's preferred role in decisions about her/his care, match the patient's preferred involvement in these decisions, present choices, discuss uncertainty, and encourage patients to obtain a second opinion.

Sharing With Patients the Uncertainties Regarding the Management of Dyspepsia

Background: The management of patients with dyspepsia is uncertain. Some authors advocate endoscopy for all; others restrict endoscopy only to patients at high risk of gastric cancer, namely to those above an age threshold, or with a family history, dysphagia, loss of weight, anemia, or a childhood in Asian countries. Still others recommend various combinations between test-and-treat for Helicobacter pylori, anti-secretory treatment, and/or endoscopy.

Objective: To highlight the uncertainties in the choice between the various strategies and argue that these uncertainties should be shared with the patient.

Method: An overview of reported life expectancy, patient satisfaction, gastric cancer detection rates, symptom relief, and cost effectiveness of the management strategies for dyspepsia.

Main Findings: There are no randomized controlled trials of the effect of screening by endoscopy on mortality of patients with gastric cancer. Lower grades of evidence suggest that early diagnosis reduces this mortality. Analyses, which assume a survival benefit of early diagnosis, indicate that mass screening in countries of high incidence gastric cancer (> 10 cases per 100,000) and targeted screening of high-risk persons in countries of low-intermediate incidence (<10 cases per 100,000) is cost-effective at a willingness to pay of $20,000–50,000 per QALY. Prompt endoscopy appears to be best for patient satisfaction and gastric cancer detection, and test-and-treat for H pylori—for symptom relief and avoiding endoscopies.

Conclusions: The gain in life expectancy is the main source of uncertainty in the choice between management strategies. This choice should be shared with the patients after explaining uncertainties and eliciting their preferences.

Proteinuria in hospitalised internal medicine adult patients

RATIONALE

Dipstick proteinuria may be a sign of a renal disorder, false-positive or associated with acute disease, and consequently, transient in hospitalised patients.

OBJECTIVE

To assess (a) the prevalence of proteinuria in hospitalised patients; (b) its association with estimated glomerular filtration rate (eGFR), findings known to cause false-positive test results and indicators of acute disease and (c) the need for follow-up after discharge.

SETTING AND PARTICIPANTS

All patients who had a dipstick urinalysis on admission to medical wards of a 400-bed regional hospital in 2018-2019.

OUTCOME VARIABLE

Proteinuria.

INDEPENDENT VARIABLES

(a) Other findings on dipstick urinalysis; (b) patients' age, gender, presence of urinary catheter and eGFR and (c) white blood cell count (WBC) and fever.

RESULTS

Of 22 329 patients, 6609 (29.6%) had urinalysis. Of those, 2973 patients (45.0%) had proteinuria of ≥+1 (≥0.30 g/L). The variables independently associated with proteinuria were other dipstick findings known to cause false-positive test results, elevated WBC, fever on presentation, presence of a urethral catheter and a low eGFR. eGFR alone was a poor predictor of proteinuria (c-stat 0.62); however, addition of the remaining independent variables to the model significantly improved its predictive ability (c-stat 0.80).

CONCLUSIONS

Dipstick proteinuria is common in hospitalised patients. Although weakly associated with eGFR, proteinuria is mainly associated with confounding factors that may result in false-positive test results. The need for follow-up of proteinuria after discharge has questionable clinical utility and its high frequency would entail a considerable cost.

Value of Troponin in Predicting Hospital Mortality of Older Adult Patients without Suspected Acute Coronary Syndromes

OBJECTIVES

Some authors have recommended troponin measurement to stratify patient mortality risk, but it is unclear whether troponin values add to age and routine admission laboratory tests in the prediction of in-hospital mortality of older adult patients without suspected acute coronary syndrome (ACS). The aim of our study was to determine whether troponin testing adds significantly to routine admission laboratory testing in predicting in-hospital mortality in patients without a suspected ACS.

METHODS

In 2018-2019, we reviewed all acutely admitted patients aged 60 years or older to Internal Medicine wards of a regional hospital after excluding those admitted to intensive care or with chest pain. The independent variables were troponin, age, sex, and routine admission laboratory tests. The outcome measure was in-hospital mortality. We compared c-statistics and the observed 10% to 90% risk gradients using logistic regression models for age and routine laboratory testing before and after the addition of troponin.

RESULTS

The mortality risk gradient for age and admission laboratory tests was 0.2% to 29.5%. Adding troponin did not increase the gradient significantly (0.2%-34.6%, P = 0.170), and the 95% confidence intervals for the c-statistics overlapped, increasing from 0.845 (0.818-0.876) to 0.866 (0.839-0.892).

CONCLUSIONS

In older adult patients without suspected ACS, troponin testing did not improve the prediction of hospital mortality above that of a model including age and common admission blood tests. In the absence of suspected ACS, troponin testing is not needed to predict the hospital mortality of older adult patients.

A simple index predicting 30-day readmissions in acutely hospitalized patients

BACKGROUND

There are various models attempting to predict 30-day readmissions of acutely admitted internal medicine patients. However, it is uncertain how to create a parsimonious index that has equivalent predictive ability and can be extrapolated to other settings.

METHODS

We developed a regression equation to predict 30-day readmissions from all acute hospitalizations in internal medicine departments in a regional hospital in 2015-2016 and validated the model in 2019. The independent (predictor) variables were age, past hospitalizations, admission laboratory test results, length of stay in hospital and discharge diagnoses. We compared the predictive value of a logistic regression model and index that included discharge diagnoses and admission laboratory test results with one that included only age, past hospitalizations, and hospital length of stay.

RESULTS

Readmission rates were associated with age, time since last hospitalization, number of previous hospitalizations, and length of stay, as well as with a diagnosis of chronic obstructive lung disease and congestive heart failure and several laboratory data. Logistic regressions of the independent variables for 30-day readmission rates were similar in 2015-2016 and 2019. An index was derived from number of previous admissions to hospitals, time since last admission, age, and length of stay. In 2019, for every unit of the index, the odds of readmission increased by 1.33 (95% CI- 1.30-1.37), and ranged from 2.1% to 37.1%. Addition of discharge diagnoses and laboratory variables did not significantly improve the risk differentiation of the index. The c-statistic for the final parsimonious model was 0.704.

CONCLUSIONS

An index derived from the number of previous hospital admissions, days since last admission, age, and length of stay in days differentiated between the risks of readmission within 30 days without the need for discharge diagnosis and laboratory variables.

A simple index predicting mortality in acutely hospitalized patients

BACKGROUND

Mortality rates used to evaluate and improve the quality of hospital care are adjusted for comorbidity and disease severity. Comorbidity, measured by International Classification of Diseases codes, do not reflect the severity of the medical condition, that requires clinical assessments not available in electronic databases, and/or laboratory data with clinically relevant ranges to permit extrapolation from one setting to the next.

AIM

To propose a simple index predicting mortality in acutely hospitalized patients.

DESIGN

Retrospective cohort study with internal and external validation.

METHODS

The study populations were all acutely admitted patients in 2015-16, and in January 2019-November 2019 to internal medicine, cardiology and intensive care departments at the Laniado Hospital in Israel, and in 2002-19, at St. James Hospital, Ireland. Predictor variables were age and admission laboratory tests. The outcome variable was in-hospital mortality. Using logistic regression of the data in the 2015-16 Israeli cohort, we derived an index that included age groups and significant laboratory data.

RESULTS

In the Israeli 2015-16 cohort, the index predicted mortality rates from 0.2% to 32.0% with a c-statistic (area under the receiver operator characteristic curve) of 0.86. In the Israeli 2019 validation cohort, the index predicted mortality rates from 0.3% to 38.9% with a c-statistic of 0.87. An abbreviated index performed similarly in the Irish 2002-19 cohort.

CONCLUSIONS

Hospital mortality can be predicted by age and selected admission laboratory data without acquiring information from the patient's medical records. This permits an inexpensive comparison of performance of hospital departments.

Duration of lead time in screening for lung cancer

BACKGROUND

Screening for lung cancer has used chest radiography (CR), low dose computed tomography (LDCT) and sputum cytology (SC). Estimates of the lead time (LT), i.e., the time interval from detection of lung cancer by screening to the development of symptoms, have been derived from longitudinal studies of populations at risk, tumor doubling time (DT), the ratio between its prevalence at the first round of screening and its annual incidence during follow-up, and by probability modeling derived from the results of screening trials.

OBJECTIVE

To review and update the estimates of LT of lung cancer.

METHODS

A non-systematic search of the literature for estimates of LT and screening trials. Search of the reference sections of the retrieved papers for additional relevant studies. Calculation of LTs derived from these studies.

RESULTS

LT since detection by CR was 0.8-1.1 years if derived from longitudinal studies; 0.6-2.1 years if derived from prevalence / incidence ratios; 0.2 years if derived from the average tumor DT; and 0.2-1.0 if derived from probability modeling. LT since detection by LDCT was 1.1-3.5 if derived from prevalence / incidence ratios; 3.9 if derived from DT; and 0.9 if derived from probability modeling. LT since detection of squamous cell cancer by SC in persons with normal CR was 1.3-1.5 if derived from prevalence/incidence ratios; and 2.1 years if derived from the DT of squamous cell cancer.

CONCLUSIONS

Most estimates of the LT yield values of 0.2-1.5 years for detection by CR; of 0.9-3.5 years for detection by LDCT; and about 2 years or less for detection of squamous cell cancer by SC in persons with normal CR. The heterogeneity of the screening trials and methods of derivation may account for the variability of LT estimates.

Johannes Juda Groen (1903-1990): A Forgotten Visionary in the History of Medical Education

Beyond the increase in medical knowledge and biotechnology during the last decades, doctors have adopted professional norms that would have been considered heretical only two generations ago. The changes transpired between the 1970s and 1990s, and generated controversies between those who upheld the traditional values of patient care, and those who welcomed the new professional norms. Professor Dr Johannes Juda Groen (1903-1990) predicted and promoted some of these changes. As early as the 1940s through the 1960s, he recognized the need to teach interviewing skills and advocated an orientation to patients, rather than to diseases; he supported decision-making based on evidence, rather than on personal experience and pathophysiologic rationale; and he demonstrated that psychosocial determinants predict, rather than only correlate with, disease. These views led to confrontations with the medical establishments in the Netherlands and in Israel. Still, many of his colleagues recognized the value of his contributions. The author, for one, admires Groen's commitment in challenging the prevailing clinical wisdom after the end of World War 2, and his courage in opposing the views of his colleagues.

Teaching the physical examination by context and by integrating hand-held ultrasound devices

Although practiced to this day, teaching the 'head-to-toe' physical examination (PE) does not appear to fully achieve its objective, and since the 1970s, there have been proposals to replace the traditional teaching of the head-to-toe examination by a selective PE aimed at testing diagnostic hypotheses; by a core PE to be supplemented by additional maneuvers as clinically indicated; and by limiting the number of PE maneuvers to be taught. The need to update the teaching of the PE is further indicated by the availability of hand-held pulse oximeters, spirometry and especially point of care ultrasound devices (PoCUS). This paper is a call to update the introduction of medical students into the PE by (a) teaching the PE by clinical contexts, rather than by organ systems, (b) restricting the number of PE maneuvers by discerning between a core of 'essential' PE signs of urgent conditions, 'important' signs that should supplement the core as clinically indicated, and 'optional' PE signs that are no longer useful, and (c) combining previously proposed alternatives of the traditional head-to-toe PE with application of hand-held ultrasound devices. We provide examples of essential, important and optional signs of the cardiovascular system.

Hypothesis: the hospital learning environment impedes students' acquisition of reflectivity and medical professionalism

Undergraduate clinical education follows the "bedside" tradition that exposes students to inpatients. However, the hospital learning environment has two main limitations. First, most inpatients require acute care, and students may complete their training without seeing patients with frequent non-emergent and chronic diseases that are managed in outpatient settings. Second, students rarely cope with diagnostic problems, because most inpatients are diagnosed in the community or the emergency room. These limitations have led some medical schools to offer longitudinal integrated clerkships in community settings instead of hospital block clerkship rotations. In this paper, I propose the hypothesis that the hospital learning environment has a third limitation: it causes students' distress and delays their development of reflectivity and medical professionalism. This hypothesis is supported by evidence that (a) the clinical learning environment, rather than students' personality traits, is the major driver of students' distress, and (b) the development of attributes, such as moral reasoning, empathy, emotional intelligence and tolerance of uncertainty that are included in the definitions of both reflectivity and medical professionalism, is arrested during undergraduate medical training. Future research may test the proposed hypothesis by comparing students' development of these attributes during clerkships in hospital wards with that during longitudinal clerkships in community settings.

Obtaining a second opinion is a neglected source of health care inequalities

Observational studies have detected discrepancies between two expert interpreters of imaging and histopathological studies. Furthermore, in a substantial proportion of patients, an independent second opinion disagreed with the first one. Therefore, it is widely accepted that patients have a right to obtain a second opinion and, in case of divergent opinions, to deliberate and choose the option that they believe is most consistent with their individual circumstances. However, doctors are less likely to inform old and poorly educated patients about the possibility of seeking a second opinion, and this may contribute to healthcare inequalities. Hence the importance of (a) promoting doctors’ self-awareness of a possible tendency to discriminate against old and poorly educated patients, and (b) creating programs within the healthcare system that would help patients in seeking a second opinion, suggest specialists for the specific problem of the patient, and provide tools to reconcile between discrepant opinions.

[FUTURE CHALLENGES OF MEDICAL EDUCATION]

Medical education faces three challenges: those related to admission policies to medical schools (can "non-academic" qualifications such as compassion and social orientation be identified?), the clinical learning environment (is "bedside" teaching the optimal way to impart clinical skills?) and the duration of medical training (can it be shortened?). I believe that over the next decades, the assessment of "non-academic" qualifications in screening medical school candidates will be the subject of critical review, and may even be canceled; the limitations of the hospital learning environment will lead to the transfer of clinical training to community clinics; and that an effort will be made to reduce the duration of medical training by splitting the curriculum into distinct career tracks, such as primary medicine, biomedical research and diagnosis by ancillary testing, secondary and tertiary clinical medicine, and epidemiology and public health.

Provision of Private Care by Doctors Employed in Public Health Institutions: Ethical Considerations and Implications for Clinical Training

This paper summarizes the difficulties that may emerge when the same care-provider attends to private and public patients within the same or different clinical settings. First, I argue that blurring the boundaries between public and private care may start a slippery slope leading to "black" under-the-table payments for preferential patient care. Second, I question whether public hospitals that allow their doctors to attend to private patients provide an appropriate learning environment for medical students and residents. Finally, I propose a way to both maintain the advantages of private care and avoid its negative consequences: complete separation between the public and the private health care systems.

Changes in wellbeing and professional values among medical undergraduate students: a narrative review of the literature

BACKGROUND

Educators are concerned by the high prevalence of emotional distress among medical students, and by the alleged decline in their humanitarian values.

OBJECTIVE

To re-examine these concerns by reviewing studies of medical students' wellbeing and development.

METHOD

Narrative review of the literature.

MAIN FINDINGS

(a) Medical students' emotional distress increases during their undergraduate training. However, although higher than in the general population, the prevalence of distress among medical students is similar to that among other university students. (b) Medical students' distress is independently related to endogenous factors (personality traits and life events) and to their perception of the medical learning environment. (c) Medical students do not display a measurable increase in moral reasoning, empathy and tolerance of uncertainty. (d) Students' wellbeing, moral development, reflectivity and tolerance of uncertainty have been shown to be interrelated, and associated with clinical performance.

CONCLUSIONS

The findings of this review endorse the concerns about the wellbeing and development of undergraduate medical students. The design of the reviewed studies does not permit inferences about causality. Yet, these findings are consistent with the hypothesis that medical training causes emotional distress that delays students' development and affects their clinical performance.

Reflections on the current and future roles of clinician-scientists

"Clinician-scientists" is an all-inclusive term for board-certified specialists who engage in patient care and laboratory-based (biomedical) research, patient-based (clinical) research, or population-based (epidemiological) research. In recent years, the number of medical graduates who choose to combine patient care and research has declined, generating concerns about the future of medical research. This paper reviews: a) the various current categories of clinician-scientists, b) the reasons proposed for the declining number of medical graduates who opt for a career as clinician-scientists, c) the various interventions aimed at reversing this trend, and d) the projections for the future role of clinician-scientists. Efforts to encourage students to combine patient care and research include providing financial and institutional support, and reducing the duration of the training of clinician-scientists. However, recent advances in clinical and biomedical knowledge have increased the difficulties in maintaining the dual role of care-providers and scientists. It was therefore suggested that rather than expecting clinician-scientists to compete with full-time clinicians in providing patient care, and with full-time investigators in performing research, clinician-scientists will increasingly assume the role of leading/coordinating interdisciplinary teams. Such teams would focus either on patient-based research or on the clinical, biomedical and epidemiological aspects of specific clinical disorders, such as hypertension and diabetes.

Role modeling in medical education: the importance of a reflective imitation

The medical literature almost uniformly addresses the positive aspects of role modeling. Still, some authors have questioned its educational value, a disagreement that is probably due to differing definitions of role modeling. If defined as demonstration of skills, provision of feedback, and emulation of specific professional behaviors, then role modeling is an important component of clinical training. However, if it is defined as a learner's unselective imitation of role models and uncritical adoption of the messages of the learning environment, then the benefits of role modeling should be weighed against its unintended harm.In this Perspective, the author argues that imitation of role models may initially help students adapt to the clinical environment. However, if sustained, imitation may perpetuate undesirable practices, such as doctor-centered patient interviewing, and unintended institutional norms, such as discrimination between private and public patients. The author suggests that the value of role modeling can be advanced not only by targeting role models and improving faculty performance but also by enhancing students' reflective assessment of their preceptors' behaviors, especially so that they can better discern those that are worth imitating. This student-centered approach may be accomplished by first, warning students against uncritically imitating preceptors who are perceived as role models; second, showing students that their preceptors share their doubts and uncertainties; third, gaining an insight into possible undesirable messages of the learning environment; and finally, developing policies for faculty recruitment and promotion that consider whether a clinical preceptor is a role model.

Undesirable features of the medical learning environment: a narrative review of the literature

The objective of this narrative review of the literature is to draw attention to four undesirable features of the medical learning environment (MLE). First, students' fears of personal inadequacy and making errors are enhanced rather than alleviated by the hidden curriculum of the clinical teaching setting; second, the MLE projects a denial of uncertainty, although to a lesser degree than in the past; third, many students feel publicly belittled and subject to other forms of abuse; and fourth, the MLE fails in overcoming students' prejudice against mental illness and reluctance to seek help when emotionally distressed. The variability of students' appreciation of the MLE across medical schools, as well as across clinical departments within medical schools, suggests that the unwanted aspects of the MLE are modifiable. Indeed, there have been calls to promote a "nurturing" MLE, in which medical students are treated as junior colleagues. It stands to reason that faculty cannot humiliate medical students and still expect them to respect patients, just as it is impossible to ignore students' distress, and still teach them to empathize with patients. Hopefully, an egalitarian attitude to students will make them also realize that they are not alone in their fears, and that their instructors share their doubts. Therefore, a major challenge of contemporary medical education is to advance a clinical MLE, where errors and uncertainties are acknowledged rather than denied, and trainees are trusted and supported, rather than judged and, occasionally, derided.

The effect of clinical interventions on hospital readmissions: a meta-review of published meta-analyses

BACKGROUND

The economic impact and ease of measurement of all-cause hospital readmission rates (HRR) have led to the current debate as to whether they are reducible, and whether they should be used as a publicly reported quality indicators of medical care.

OBJECTIVE

To assess the efficacy of broad clinical interventions in preventing HRR of patients with chronic diseases

METHOD

A meta-review of published systematic reviews of randomized controlled trials (RCTs) of clinical interventions that have included HRR among the patients' outcomes of interest.

MAIN FINDINGS

Meta-analyses of RCTs have consistently found that, in the community, disease management programs significantly reduced HRR in patients with heart failure, coronary heart disease and bronchial asthma, but not in patients with stroke and in unselected patients with chronic disorders. Inhospital interventions, such as discharge planning, pharmacological consultations and multidisciplinary care, and community interventions in patients with chronic obstructive pulmonary diseases had an inconsistent effect on HRR. MAIN STUDY LIMITATION: Despite their economic impact and ease of measurement, HRR are not the most important outcome of patient care, and efforts aimed at their reduction may compromise patients' health by reducing also justified re-admissions.

CONCLUSIONS

The efficacy of inhospital interventions in reducing HRR is in need of further study. In patients with heart diseases and bronchial asthma, HRR may be considered as a publicly reported quality indicator of community care, provided that future research confirms that efforts to reduce HRR do not adversely affect other patients' outcomes, such as mortality, functional capacity and quality of life. Future research should also focus on the reasons for the higher efficacy of community interventions in patients with heart diseases and bronchial asthma than in those with other chronic diseases.

Objectives of teaching direct ophthalmoscopy to medical students

PURPOSE

To propose the objectives of undergraduate training in direct ophthalmoscopy (DO).

METHOD

Narrative review of the literature on (i) opinions about the expected proficiency from students in DO, and (ii) estimates of its diagnostic value.

RESULTS

(i) Authorities disagree on the proficiency in DO that they expect from students. Textbooks of physical diagnosis differ in their coverage of DO. Surveys have indicated that US physicians expect students to be able to detect optic nerve head abnormalities. The Association of American Medical Colleges expects students to perform ophthalmoscopic examination and describe observations. The International Council of Ophthalmology expects students to recognize also diabetic and hypertensive retinopathies. The Association of University Professors in Ophthalmology requires that students recognize papilloedema, cholesterol emboli, glaucomatous cupping and macular degeneration. (ii) There is evidence that DO, even by ophthalmologists, is inadequate for screening for glaucoma, diabetic and hypertensive retinopathies. Two studies have suggested a limited value of DO in detecting clinical emergencies.

CONCLUSIONS

The evidence that DO, even by ophthalmologists, is sub-optimal in detecting common abnormalities challenges existing the notions of training medical students. On pending the results of additional studies of the value of DO in detecting emergencies, we suggest that undergraduate teaching of DO should impart the following: (i) an ability to identify the red fundus reflex and optic disc; (ii) an ability to recognize signs of clinical emergencies in patients, mannequins or fundus photographs; and (iii) knowledge about, but not an ability to detect, other retinopathies.

Expected benefits of streamlining undergraduate medical education by early commitment to specific medical specialties

Undergraduate medical education is too long; it does not meet the needs for physicians' workforce; and its content is inconsistent with the job characteristics of some of its graduates. In this paper we attempt to respond to these problems by streamlining medical education along the following three reforms. First, high school graduates would be eligible for undergraduate medical education programs of 4 years duration. Second, medical school applicants would be required to commit themselves to a medical specialty and choose one of four undergraduate paths: (1) "Interventions/consultations" path that would prepare its graduates for residencies in secondary and tertiary specialties, such as cardiology and surgery, (2) "continuous patient care" path for primary care specialties, such as family medicine and psychiatry, (3) "diagnostic laboratory medicine and biomedical research" path that would prepare for either laboratory-based careers, such as pathology, biochemistry and bacteriology, or research in e.g., immunology and molecular genetics, and (4) "epidemiology and public health" path that would include population-based research, preventive medicine and health care administration. Third, the content of each of these paths would focus on relevant learning outcomes, and medical school graduates would be eligible for residency training only in specialties included in their path. Hopefully, an early commitment to a medical specialty will reduce the duration of medical education, improve the regulation of physicians' workforce and adapt the curricular content to the future job requirements from medical school graduates.

What the United States could learn from Israel about improving the quality of health care

In 1999 Israel began to implement a system for monitoring quality of care in its health plans. That system was based largely on a similar system in the United States that, until recently, was associated with steady improvements in performance. However, in recent years health plan quality in the United States appears to have reached a plateau. In contrast, health plans in Israel have continued to show improvements on many of the same measures. Between 2005 and 2007 they achieved a gain of 6.7 percent in nine measures of primary care quality, while US performance on these measures declined. These gains were achieved, in part, through intense cooperation among health plans and physicians. Israel is a much smaller country and differs greatly from the United States in how it finances health care. Nonetheless, we suggest that the Israeli experience could help the United States accelerate the move toward quality improvement-for example, through increased coordination among US employers, health plans, physicians, and physician groups.

Sources of distress during medical training and clinical practice: Suggestions for reducing their impact

BACKGROUND

Medical students and doctors experience several types of professional distress. Their causes ("stressors") are commonly classified as exogenous (adapting to medical school or clinical practice) and endogenous (due to personality traits). Attempts to reduce distress have consisted of providing students with support and counseling, and improving doctors' management of work time and workload.

AIM

To review the common professional stressors, suggest additional ones, and propose ways to reduce their impact.

METHOD

Narrative review of the literature.

RESULTS AND CONCLUSION

We suggest adding two professional stressors to those already described in the literature. First, the incongruity between students' expectations and the realities of medical training and practice. Second, the inconsistencies between some aspects of medical education (e.g., its biomedical orientation) and clinical practice (e.g., high proportion of patients with psychosocial problems). The impact of these stressors may be reduced by two modifications in undergraduate medical programs. First, by identifying training-practice discrepancies, with a view of correcting them. Second, by informing medical students, both upon admission and throughout the curriculum, about the types and frequency of professional distress, with a view of creating realistic expectations, teaching students how to deal with stressors, and encouraging them to seek counseling when needed.

Adherence to standards of care by health maintenance organizations in Israel and the USA

BACKGROUND

The health-care systems in the USA and Israel differ in organization, financing and expenditure levels. However, managed care organizations play an important role in both countries, and a comparison of the performance of their community-based health plans could inform policymakers about ways to improve the quality of care.

OBJECTIVE

To compare the adherence to standards of care in Israel and in the USA.

STUDY DESIGN

An observational study comparing trends in performance using data from reports of the National Quality Measures Program in Israel and of the National Committee for Quality Assurance in the USA.

RESULTS

Differences in specifications preclude a comparison between most measures in the two reports. However, the comparison of 11 similar measures in the 2007 reports indicates that performance was higher in the USA by 10 or more percentage points on four measures (flu immunization, medication for asthma, screening for colorectal cancer and monitoring for diabetic nephropathy). Performance was higher in Israel on three measures in patients with diabetes (blood pressure, low-density lipoprotein (LDL) cholesterol and glycemic control), and similar on the remaining four measures. Between 2005 and 2007, quality of care improved in both countries. However, improvement was slower in the USA than in Israel.

CONCLUSIONS

In comparison with the USA, Israel achieves comparable health maintenance organization (HMO) quality on several primary care indicators and more rapid quality improvement, despite its substantially lower level of expenditure. Considering the differences between the two countries in settings and populations, further research is needed to assess the causes, generalizability and policy implications of these findings.

Narrative review: should teaching of the respiratory physical examination be restricted only to signs with proven reliability and validity?

OBJECTIVE

To review the reported reliability (reproducibility, inter-examiner agreement) and validity (sensitivity, specificity and likelihood ratios) of respiratory physical examination (PE) signs, and suggest an approach to teaching these signs to medical students.

METHODS

Review of the literature. We searched Paper Chase between 1966 and June 2009 to identify and evaluate published studies on the diagnostic accuracy of respiratory PE signs.

RESULTS

Most studies have reported low to fair reliability and sensitivity values. However, some studies have found high specificites for selected PE signs. None of the studies that we reviewed adhered to all of the STARD criteria for reporting diagnostic accuracy.

CONCLUSIONS

Possible flaws in study designs may have led to underestimates of the observed diagnostic accuracy of respiratory PE signs. The reported poor reliabilities may have been due to differences in the PE skills of the participating examiners, while the sensitivities may have been confounded by variations in the severity of the diseases of the participating patients. IMPLICATION FOR PRACTICE AND MEDICAL EDUCATION: Pending the results of properly controlled studies, the reported poor reliability and sensitivity of most respiratory PE signs do not necessarily detract from their clinical utility. Therefore, we believe that a meticulously performed respiratory PE, which aims to explore a diagnostic hypothesis, as opposed to a PE that aims to detect a disease in an asymptomatic person, remains a cornerstone of clinical practice. We propose teaching the respiratory PE signs according to their importance, beginning with signs of life-threatening conditions and those that have been reported to have a high specificity, and ending with signs that are "nice to know," but are no longer employed because of the availability of more easily performed tests.

A proposal for overcoming problems in teaching interviewing skills to medical students

The objective of this paper is to draw attention to four features that distinguish the pedagogy of patient interviewing from the teaching of other clinical skills: (a) students are not naïve to the skill to be learned, (b) they encounter role models with a wide variability in interviewing styles, (c) clinical teachers are not usually specialists in the behavioral sciences, including patient interviewing, and (d) the validity of the methods used for assessment of interviewing skills is uncertain. We propose to adjust the teaching of patient interviewing to these features by (a) gaining an insight into the students' views and using these views as a point of departure for discussions of patient interviewing; (b) helping students to understand why different clinicians use different communication styles; (c) providing the clinical tutors with additional training that will help them function as both specialists who share their expertise with the students and facilitators of small-group learning; and (d) using assessment methods that encourage joint deliberation by the learner and the examiner, rather than a judgmental right-wrong dualism by the examiner alone. The teaching approach that we suggest is consistent with current theories of adult learning, and it occurs in an egalitarian rather than a hierarchical environment. Hopefully, students will also adopt such egalitarian attitudes toward patients, thereby reducing the tendency to a paternalistic communication style.

Reliability of screening methods for diabetic retinopathy

AIM

To review studies of the reliability (reproducibility) of the commonly used methods (ophthalmoscopy and inspection of retinal images) of screening for diabetic retinopathy (DR).

RESEARCH DESIGN AND METHODS

Literature search.

RESULTS

We found six studies of the intra-examiner agreement after examining the same retinal images. Three of these found an almost perfect agreement (k > 0.8) after inspecting colour slides and digital images; three other studies reported 'significant differences' in microaneurysm counts and only 39-85% agreement rates between two assessments by the same examiner. The inter-examiner agreement was reported in 24 studies. Using stereoscopic photographs, one study found almost perfect agreement after examining seven fields; another study found a substantial to moderate (k = 0.4-0.8) agreement after examining five fields and a third study found a fair agreement (k = 0.2-0.4) after examining a single field. Studies using single- or two-field monoscopic photographs also have reported agreement rates that have varied between almost perfect, substantial and moderate. In four other studies using biomicroscopy, agreement levels varied between perfect and moderate.

CONCLUSIONS

Relative to the large number of studies on the validity of the various methods for screening for DR, there are only few studies of their reliability, with a marked variability in their findings. We suggest that future studies of the effectiveness of the various methods for screening for DR should also include data on their reliability.

Current trends in the educational approach for teaching interviewing skills to medical students

Research in the acquisition of patient interviewing skills by medical students has dealt mostly with the evaluation of the effectiveness of various teaching programs and techniques. The educational approaches (i.e., the tutor-learner relationship and learning atmosphere) have rarely been discussed. These approaches may be grouped into: a) "teacher-centered" (didactic), in which the students are passive recipients of instruction; b) "learner-centered," in which the tutor functions as a facilitator of small group learning, whose task is not to teach but rather to ensure that all students participate in the discussions and share knowledge with other students; and c) "integrated learner-and teacher-centered" or "experiential learning," which consists of an ongoing dialogue between the tutor and the students. In this paper, we review the strengths and weaknesses of these educational approaches and attempt to identify the current trends in their use in the teaching of interviewing skills. It would appear that until the 1960s, medical students acquired interviewing skills without any expert guidance. On the other hand, since the 1970s, there has been a tendency to offer and upgrade undergraduate programs aimed at imparting communication skills to medical students. Initially, these programs were didactic; however, during the last decade, there has been an increasing shift to teaching interviewing skills by promoting experiential learning.

[Medical specialties in crisis: causes of the crisis and possible solutions]

BACKGROUND

Several clinical specialties in Israel appear to be experiencing an ongoing crisis. In this paper the authors report a pilot case study of general surgery and internal medicine, which have been identified as "clinical specialties in crisis" in the medical literature, during preliminary interviews and in the testimonies presented to a Public Committee appointed by the Prime Minister (the Amorai Committee) that addressed this problem in 2002.

OBJECTIVES

To identify the causes of the crisis and possible solutions.

METHODS

Qualitative analysis of interviews and written testimonies of hospital directors, departmental heads of general surgery and internal medicine, key personnel in the Israeli health care system and heads of scientific associations abroad.

RESULTS

The causes of the crisis in general surgery and internal medicine appear to be at three different levels: those related to the health system and its environment; causes related to the organizational structure of the hospitals; and causes inherent to the characteristics of the relevant medical specialty. The solutions proposed by the respondents in Israel, Europe and the United States should be considered at each of these levels: at the system-wide level (such as increase in tenured positions, and improvements in the residency programs); at the hospital level (such as the addition of auxiliary paramedical employees with a view to reduce the administrative burden of the physicians); and at the level of the specific medical specialty (such as the development of new subspecialties, e.g., acute care surgeons).

CONCLUSIONS

It is possible to identify the perceived causes of the crisis and possible ways of coping with their consequences. The findings of this pilot study justify a broader survey of additional medical specialties and a larger number of physicians.

[Criteria for a medical specialty in crisis: a case study of general surgery and internal medicine]

BACKGROUND

Several clinical specialties in Israel appear to be experiencing an ongoing crisis. Recently, a Public Committee addressed this problem and recommended its further study. In this paper, the authors report a pilot case study of general surgery and internal medicine, which have been identified as "clinical specialties in crisis" in the medical literature, in the testimonies presented to the Public Committee, and during our preliminary interviews.

OBJECTIVES

to identify (a) the criteria for a "medical specialty in crisis" and (b) measures for the assessment of the extent of the crisis.

METHODS

(a) Qualitative analysis of interviews and written testimonies of hospital directors, departmental heads of general surgery and internal medicine, and key personnel in the health care system; (b) Analysis of data derived from national administrative data databases and (c) Secondary analysis of data from a nationwide survey of board certified Israeli specialists.

RESULTS

We identified five criteria of "medical specialties in crisis": shortage of "good" applicants for residency training; difficulties in filling vacant positions; excessive workload due to the limited number of staff physician and residents; a perceived low remuneration and limited opportunities for additional income; poor quality of professional working life. Some of these criteria can be used as a proxy for measuring the extent of the crisis.

CONCLUSIONS

It is possible to identify criteria defining clinical specialties in crisis, as well as its extent, as a first step toward identification of possible ways of coping with it. The findings of this pilot study justify a broader survey of additional medical specialties and a larger number of physicians.

Primary care physicians' discussion of emotional distress and patient satisfaction

OBJECTIVES

To assess: a) the prevalence and determinants of self-reported emotional distress in the Israeli population; b) the rate of self-reported discussion of emotional distress with family physicians; and c) the association between such discussions and patient satisfaction with care.

DESIGN

Retrospective, cross-sectional survey that was conducted through structured telephone interviews in Hebrew, Arabic, and Russian. This study was part of a larger study assessing patients' perceptions of the quality of health services.

PARTICIPANTS

A representative sample of 1,849 Israeli citizens aged 22 to 93 (response rate: 84%).

INDEPENDENT VARIABLES

Gender, age, ethnicity (spoken language), education, income, self-reported chronic disease, self-reported episode(s) of emotional distress during the last year, and having discussed emotional distress with the family physician.

OUTCOME MEASURE

satisfaction with care.

RESULTS

28.4% reported emotional distress and 12.5% reported discussion of emotional distress with a primary care physician in the past year. Logistic regression identified female gender, Arab ethnicity, low income, and chronic illness as independent correlates of emotional distress. These as well as Russian speakers and having experienced emotional distress during the past year were identified as independent correlates of discussion of emotional distress with the family physician. Patients who reported discussion of emotional distress with their family physician were significantly more satisfied with care.

CONCLUSIONS

Encouraging physicians to detect and discuss emotional distress with their patients may increase patient satisfaction with care, and possibly also improve patients' well-being and reduce health care costs.

Uncertainties in the selection of applicants for medical school

Decisions about admissions to medical school are based on assessments of the applicants' cognitive achievements and non-cognitive traits. Admission criteria are expected to be fair, transparent, evidence-based and legally defensible. However, unlike cognitive criteria, which are highly reliable and moderately valid, the reliability and validity of the non-cognitive criteria are low or uncertain. Their uncertain predictive value is due not only to their limited validity, but also to the unknown prevalence of the desirable non-cognitive traits in the applicants' pool. Consequently, the use of non-cognitive admission criteria inevitably leads to rejection of an unknown proportion of applicants who have a desirable trait and selection of applicants who lack this trait. We propose that, rather than using non-cognitive admission criteria, admission officers should assist prospective applicants to make informed decisions based on a reflective self-appraisal whether or not to apply to medical school. To this end, medical schools should disseminate information on the strains of medical training and practice, the frequency of medical errors and the most common causes of dissatisfaction and burn-out among practicing physicians. Such information may improve the self-selection process and thereby enrich the applicants' pool for individuals with appropriate motivation. The final selection of medical students may then be based either on past academic achievements, or on a lottery, or on various combinations thereof.

A practical assessment of physician biopsychosocial performance

BACKGROUND

A biopsychosocial approach to care seems to improve patient satisfaction and health outcomes. Nevertheless, this approach is not widely practiced, possibly because its precepts have not been translated into observable skills.

AIM

To identify the skill components of a biopsychosocial consultation and develop an tool for their evaluation.

METHODS

We approached three e-mail discussion groups of family physicians and pooled their responses to the question "what types of observed physician behavior would characterize a biopsychosocial consultation?" We received 35 responses describing 37 types of behavior, all of which seemed to cluster around one of three aspects: patient-centered interview; system-centered and family-centered approach to care; or problem-solving orientation. Using these categories, we developed a nine-item evaluation tool. We used the evaluation tool to score videotaped encounters of patients with two types of doctors: family physicians who were identified by peer ratings to have a highly biopsychosocial orientation (n = 9) or a highly biomedical approach (n = 4); and 44 general practitioners, before and after they had participated in a program that taught a biopsychosocial approach to care.

RESULTS

The evaluation tool was found to demonstrate high reliability (alpha = 0.90) and acceptable interobserver variability. The average scores of the physicians with a highly biopsychosocial orientation were significantly higher than those of physicians with a highly biomedical approach. There were significant differences between the scores of the teaching-program participants before and after the program.

CONCLUSIONS

A biopsychosocial approach to patient care can be characterized using a valid and easy-to-apply evaluation tool.

The Association Between Inquiry About Emotional Distress and Women's Satisfaction with Their Family Physician: Findings from a National Survey

BACKGROUND

Women appear to be more vulnerable than men to emotional distress (ED) However, ED often goes unrecognized by family physicians.

PURPOSE

To (1) assess the rate of inquiry about ED by family physicians and (2) explore the association between physician's inquiry about ED and women's satisfaction with care.

METHODS

Telephone interviews were conducted in 2003 using a structured questionnaire in a representative sample of 991 Israeli women aged 22 years or older, with a response rate of 84%.

RESULTS

33% of women reported ED during the past year but only 15% of women reported having discussed ED with their family physician in the last year. Higher rates of discussion of ED with the physician were found among women who had experienced ED (22.5%), those who had a chronic illness (20.1%) had low income (22.7%), and were Arabic (29.5%) or Russian speakers (26.3%). Multivariate analysis indicated that women who had discussed ED with their physician expressed higher satisfaction with the physicians professional level (OR = 6.85), attitude (OR = 2.45), spending enough time (OR = 2.90), and listening to the patient (OR = 3.19), compared with women who had not discussed ED with their physician.

CONCLUSIONS

Given the current low rates of inquiry about ED, it appears that developing sensitivity to women's emotional concerns and encouraging physicians to inquire about ED should be given higher priority in medical education at all levels. Furthermore, since inquiry about ED not only improves the appropriateness of care but is also associated with higher satisfaction with the physician, organizations in a competitive health care environment may have a particular interest in promoting this practice.

The time horizons of formal decision analyses

Clinical decision analyses use time horizons that vary from hours to the patient's entire life. Analyses of decisions with a lifetime horizon commonly use Markov models, which simulate the patient's lifespan by dividing it into equal periods (cycles). At each cycle, the model exposes a hypothetical cohort to the competing hazards of normal aging and of the disease in question (disease-specific hazards), and the results are presented as years of life expectancy. This paper highlights two limitations of lifetime Markov models that have been ignored in recent publications. First, since there are no readily available data on changes in disease-specific hazards over time, these hazards are often derived from short-term follow-up studies, and assumed to be constant over the patient's entire life. Second, results may be better presented in terms of health states (i.e. proportions of patients expected to recover completely, recover with a disability or die) rather than life expectancy. Although well-known, these two limitations require re-emphasis. They may be avoided by restricting the time horizon of decision analyses and presenting results as health states as well as life expectancies. When a lifetime horizon is necessary, the performance of Markov models may be improved by the using of time-variant disease-specific hazards derived from long-term follow-up studies, or from theoretical models that simulate more closely the disease progression over time, rather than assuming constant disease-specific hazards.

A proposal for teaching basic clinical skills for mastery: the case against vertical integration

The authors argue that medical school faculty should (1) make a distinction among competencies that they feel need to be taught for mastery (i.e., at a level of proficiency expected from a practicing physician) and those that should be taught at lower levels of proficiency, and (2) impart the former competencies in single teaching units. The authors propose that the skills that students should be expected to master include patient interviewing, physical examination, patient counseling on health promotion and disease prevention (HP/DP), and self-directed learning. The concepts of a hypothetical teaching unit that aims to impart these skills are described. By the end of this unit, the students would be expected to (1) examine simulated and real patients to detect risk indicators and physical findings for the diseases that are the most common causes of death in the patient's gender and age group, and to look for risk indicators and physical findings for diseases where early diagnosis and treatment have been shown to reduce mortality for such patients, and (2) provide counseling for lifestyle changes and future clinical examinations. The authors believe that the objective of acquiring an ability to counsel a patient on HP/DP at the level of competence of a practicing physician will motivate students to acquire the skills of patient interviewing, physical examination, and self-directed learning more effectively than would a succession of reinforcements of these subjects throughout the curriculum.
