Low job satisfaction predicts delayed return to work after laparoscopic cholecystectomy.

We studied 102 consecutive employed patients treated by elective laparoscopic cholecystectomy to determine job characteristics and psychological factors that predict delay in return to work after their procedure. Median sick leave was 13 days, and five variables significantly added to a model predicting sick leave of at least 20 days (31.4% of the workers): low job satisfaction (odds ratio [OR], 12.56; 95% confidence interval [CI], 3.34 to 47.2); physical effort at work (OR, 4.99; 95% CI, 1.46 to 17.04); pain at 7 days (OR, 5.55; 95% CI, 1.56 to 19.76); patient's expectation of slow recovery (> 7 days) (OR, 6.12; 95% CI, 1.82 to 20.55); and patient's expectation of no financial loss (OR, 3.85; 95% CI, 1.14 to 12.50). The model was excellent (area under the receiver operating characteristic curve, 89.6%). We conclude that low job satisfaction is a major predictor of delayed return to work.

A cross-national study of acute otitis media: risk factors, severity, and treatment at initial visit. Report from the International Primary Care Network (IPCN) and the Ambulatory Sentinel Practice Network (ASPN).

BACKGROUND: Treatment of acute otitis media (AOM) differs worldwide. The Dutch avoid antimicrobials unless fever and pain persist; the British use them for 5 to 7 days, and Americans use them for 10 days. If effects of therapies are to be compared, it is necessary to evaluate rates of risk factors, severity of attacks, and their influence on treatment decisions. We wanted to compare the prevalence of risk factors for AOM and evaluate their association with severity of attacks and of severity with antimicrobial treatment. METHODS: We undertook a prospective cohort study of 2,165 patients with AOM enrolled by primary care physicians; 895 were enrolled from North America, 571 were enrolled from the United Kingdom, and 699 were enrolled from The Netherlands. The literature was searched using the key words "acute otitis media," "severity," and "international comparisons." RESULTS: The prevalence of several AOM risk factors differs significantly among patients from the three country networks; these factors include race, parent smoking habits, previous episodes, previous episodes without a physician visit, tonsillectomy or adenoidectomy, frequency of upper respiratory tract infections, day care, and recumbent bottle-feeding. Dutch children have the most severe attacks as defined by fever, ear discharge, decreased hearing during the previous week, and moderate or severe ear pain. In country-adjusted univariate analyses, increasing age, exposure to tobacco smoke, day care, previous attacks of AOM, previous attacks without physician care, past prophylactic antimicrobials, ear tubes, adenoidectomy, and tonsillectomy all contribute to severity. Only country network, age, history of AOM, previous episode without physician care, and history of adenoidectomy and tympanostomy tubes are independently related to increased severity, while current breast-feeding is protective. Severity of attacks influences treatment decisions. Dutch children are least likely to receive antimicrobials, and even for severe attacks the British and Dutch physicians usually use amoxicillin or trimethoprim-sulfa; North American children with severe attacks are more likely to receive a broad-spectrum second-line antimicrobial. CONCLUSION: Dutch children have the highest ratings in all severity measures, possibly reflecting parental decisions about care seeking for earaches. When comparing groups of patients with AOM, it is necessary to adjust for baseline characteristics. Severity of episode affects physician treatment decisions. Adoption of Dutch guidelines restricting use of antimicrobials for AOM in the United States could result in annual savings of about $185 million.

Tympanometry interpretation by primary care physicians. A report from the International Primary Care Network (IPCN) and the Ambulatory Sentinel Practice Network (ASPN).

BACKGROUND: The accuracy of data gathered by primary care clinicians in practice-based research networks (PBRNs) has been questioned. Tympanometry, recently recommended as a means of improving accuracy of diagnosing acute otitis media, was included as an objective diagnostic measure in an international PBRN study. We report the level of agreement of interpretations of tympanograms between primary care physicians in PBRNs and experts. METHODS: Primary care physicians in PBRNs in the Netherlands, United Kingdom, United States, and Canada enrolled 1773 children aged 6 to 180 months who contributed 6358 tympanograms during 3179 visits. The physicians were trained in the use and interpretation of tympanometry using the Modified Jerger Classification. We determined the level of agreement between physicians and experts for interpretation of tympanograms. One comparison used the 6358 individual ear tracings. A second comparison used the 3179 office visits by children as the unit of analysis. RESULTS: The distribution of expert interpretation of all tympanograms was: 35.8% A, 30% B, 15.5% C1, 12% C2, and 6.8% uninterpretable; for visits, 37.8% were normal (A or C1), 55.6% abnormal (B or C2), and 6.6% could not be classified. There was a high degree of agreement in the interpretation of tympanograms between experts and primary care physicians across networks (kappa=0.70-0.77), age groups of children (kappa=0.69-0.73), and types of visits (kappa=0.66-0.77). This high degree of agreement was also found when children were used as a unit of analysis. CONCLUSIONS: Interpretations of tympanograms by primary care physicians using the Modified Jerger Classification can be used with confidence. These results provide further evidence that practicing primary care physicians can provide high-quality data for research purposes.

The urgent need to improve hypertension care.

Hypertension is the most prevalent health problem among adult primary care patients, but its recognition and treatment are suboptimal. Although there is ample evidence from several large-scale randomized, controlled studies that treatment of hypertension reduces morbidity and mortality, current management of hypertension is characterized by underdiagnosis, misdiagnosis, undertreatment, overtreatment, and misuse of medications. As a result, roughly 75% of the estimated 50 million adults with hypertension in the United States are at increased risk for vascular complications. Optimal therapy requires careful attention to patients' age, sex, race, diet, exercise, tobacco use, comorbid conditions, choice of antihypertensive drug treatment, compliance with treatment, and achievement of blood pressure control. Other issues that deserve scrutiny are accuracy of the initial diagnosis, self-monitoring of blood pressure, and the advisability of attempting reduction of dosage or possible withdrawal from administration of antihypertensive drug treatment in patients whose blood pressures have been controlled for 1 year or more. Physicians' knowledge and use of the Sixth Joint National Committee on Prevention, Detection, and Treatment of High Blood Pressure report are deficient. Several responses to this current crisis in care of hypertensive patients are reviewed, including computer-aided management, medical chart audit, academic detailing, and a nurse case manager using prepared algorithms in consultation with the physician.

Reducing antihypertensive medication use in nursing home patients.

Of the 1.5 million nursing home residents, about 40% are aged 85 years or older, and a similar percentage have hypertension. The rates of incorrect diagnoses from the "white coat" effect and from errors in blood pressure evaluation are as frequent in older persons as in younger persons. The benefits of antihypertensive treatment and the risks of lowering blood pressures in the very old (> or = 85 years) are uncertain. Elderly patients experience adverse effects from drug treatment that are unique to their age group and that complicate management problems associated with polypharmacy and multiple comorbid conditions. Trials to withdraw or lower the dosage of antihypertensive medications have been successful in up to 40% of elderly persons when combined with salt restriction and weight loss, but such studies are lacking in nursing home patients. The management of hypertension should be reevaluated in nursing home patients.

Hypertension in nursing home patients.

There have been few studies of hypertension in nursing home patients. To assess the prevalence, demographic characteristics, comorbidity and drug therapy in hypertensive nursing home patients compared with those who are normotensive, we reviewed all medical charts of patients in three nursing home facilities. Of the 804 patients, 355 (44.2%) have hypertension. Calcium channel blockers were the most frequently prescribed anti-hypertensive (30.3%) and together with diuretics (28.4%) and ACE inhibitors (27.7%) account for more than 85%. Hypertensive patients take more cardiac, hypoglycaemic, and analgesic drugs (P = <0.001, <0.001, and 0.004, respectively) than those who are normotensive. Overall patients take an average of 8.68 medications daily. In hypertensive patients, the average number of comorbid conditions (excluding hypertension) is 5.02 compared with 3.23 in normotensive patients. Hypertension is significantly associated with diabetes, heart disease, cerebrovascular disease, neoplasms, endocrine disorders, gastrointestinal diseases, psychiatric disorders, dementia, other central nervous system diseases, skin problems, blood diseases and inversely with hip fracture. Blood pressure control (<140/90 mm Hg) is achieved in 88.8%, is not related to age and is significantly more frequent in males than females (91.8% vs 82.6% P = 0.025). The problem of hypertension in nursing home patients is complex and has received insufficient study. Since studies demonstrating benefit from anti-hypertensive therapy in the elderly excluded the very elderly and those with significant comorbid conditions, additional research is needed.

Measurement and management of hyperlipidemia for the primary prevention of coronary heart disease.

BACKGROUND: As part of the National Cholesterol Education Program (NCEP) two expert panel reports (1988, 1993) recommend serum cholesterol measurements in all adults aged 20 years and older and cholesterol-lowering treatment for those with abnormal levels. METHODS: All major drug intervention trials for primary prevention of coronary heart disease were reviewed. Similarly, selected studies on risks of dyslipidemia and benefit of therapy for the elderly and for women without coronary heart disease were analyzed. These studies were evaluated to test the soundness of the NCEP panel's recommendations. RESULTS AND CONCLUSIONS: Five major randomized drug intervention trials for primary prevention of coronary heart disease showed that cholestyramine, gemfibrozil, clofibrate, and pravastatin can reduce the rate of nonfatal myocardial infarctions in middle-aged men. All-cause and ischemic heart disease mortality were increased by clofibrate and unaffected by the other three drugs. Extrapolation of these findings to women and older and younger men is unwarranted because there is no evidence that either diet or drugs provide primary protection from coronary heart disease in these groups. It is uncertain whether dyslipidemia is a risk factor for coronary heart disease in the elderly. The annual cost of drugs for full implementation of the panel's recommendations ranges from $6 billion to $11.5 billion and an additional $13 billion will be required for initial screening, classifying, and monitoring serum cholesterol levels. Potential adverse consequences of a national program include possible risks from low cholesterol levels, drug side-effects, and disease labeling.

Clinical practice guidelines on depression: awareness, attitudes, and content knowledge among family physicians in New York.

BACKGROUND: In 1989, the federal government mandated that the Agency for Health Care Policy and Research (AHCPR) appoint expert panels to develop clinical practice guidelines to define standards for the provision and quality of health care. There is uncertainty about physicians' awareness and attitudes concerning guidelines. METHODS: We surveyed 992 members of the New York State Academy of Family Physicians. In addition to demographic data, respondents were questioned about awareness of AHCPR guidelines for depression in primary care, urinary incontinence, and pressure ulcers in adults; knowledge of the diagnosis and treatment of depression; and general attitudes about guidelines. RESULTS: Three mailings produced a response rate of 53.2%. While 90.5% of respondents treat depression in their primary care practices, only 33.6% are aware of the existence of the guidelines on depression 1 year after publication. Only 13.1% of respondents have a copy of the guidelines. Physicians are slightly less aware of the guidelines on urinary incontinence and pressure ulcers (30.0%). Respondents are generally knowledgeable about the diagnosis and treatment of depression, and board certification is correlated with increased knowledge about the treatment of recurrent depression. Logistic regression analyses demonstrate that female family physicians, those living in larger communities, and physicians with 3 or more years of training are most likely to have positive attitudes toward guidelines. CONCLUSIONS: The AHCPR guidelines failed to reach their targeted audience. Specific strategies derived from survey data can identify physicians who may most benefit from educational interventions.

Asymptomatic microscopic hematuria--is investigation necessary?

Microscopic hematuria is common in asymptomatic adults, but the benefit of screening the general population for blood in the urine has not been established. On the other hand, most studies of referred patients with putatively asymptomatic microscopic hematuria have reported a 2-11% prevalence of urothelial malignancies, leading to the recommendation that all patients with microscopic hematuria be thoroughly investigated. Urinalysis is inexpensive and highly acceptable to the general population, but is neither a sensitive, nor specific test, and has poor predictive value for urothelial malignancies, and nephrological diseases. Furthermore the benefits of early detection of such diseases has not been established. We conclude that screening urinalysis cannot be recommended. Studies are needed to determine which constellation of findings primary physicians use to select patients for referral to centers with urological and nephrological expertise.

Withdrawal of antihypertensive medications.

BACKGROUND: Pharmacologic treatment of hypertension reduces risks of stroke, congestive heart failure, renal failure, and mortality, but whether medications, once begun, need to be continued for life is uncertain. METHODS: Several search strategies on MEDLINE using key words "medication," "withdrawal," "discontinuance," and "therapy" in several combinations, nested within "hypertension," were not productive. Accordingly, articles known to the authors and citations within them were reviewed. A survey of a random sample of members of the New York Academy of Family Practice was conducted to ascertain current practice of practicing physicians. RESULTS: Eighteen studies of antihypertensive medication withdrawal were located and all were reviewed. In 12 trials average success rates of 40.3 percent after 1 year of follow-up and 27.7 percent after 2 years were achieved. In six studies limited to elderly patients, an average success rate of 26.2 percent was obtained for periods of 2 or more years. The trials, however, were heterogeneous in design, patient selection criteria, and follow-up. The survey of family physicians indicated that 79.1 percent attempt withdrawal of antihypertensive medications in hypertensive patients whose blood pressure is controlled and who are without symptoms from medication. CONCLUSIONS: We conclude that successful withdrawal of antihypertensive medications can have substantial benefits with few or no adverse consequences and might be successful in about one third of patients. Additional research is required to substantiate rates of successful medication withdrawal, to define the best method of withdrawing medications, and to delineate characteristics of patients in whom withdrawal is most likely to succeed.

The National Depressive and Manic-Depressive Association consensus statement on the undertreatment of depression.

OBJECTIVE: A consensus conference on the reasons for the undertreatment of depression was organized by the National Depressive and Manic Depressive Association (NDMDA) on January 17-18, 1996. The target audience included health policymakers, clinicians, patients and their families, and the public at large. Six key questions were addressed: (1) Is depression undertreated in the community and in the clinic? (2) What is the economic cost to society of depression? (3) What have been the efforts in the past to redress undertreatment and how successful have they been? (4) What are the reasons for the gap between our knowledge of the diagnosis and treatment of depression and actual treatment received in this country? (5) What can we do to narrow this gap? (6) What can we do immediately to narrow this gap? PARTICIPANTS: Consensus panel members were drawn from psychiatry, psychology, family practice, internal medicine, managed care and public health, consumers, and the general public. The panelists listened to a set of presentations with background papers from experts on diagnosis, epidemiology, treatment, and cost of treatment. EVIDENCE: Experts summarized relevant data from the world scientific literature on the 6 questions posed for the conference. CONSENSUS PROCESS: Panel members discussed openly all material presented to them in executive session. Selected panelists prepared first drafts of the consensus statements for each question. All of these drafts were read by all panelists and were edited and reedited until consensus was achieved. CONCLUSIONS: There is overwhelming evidence that individuals with depression are being seriously undertreated. Safe, effective, and economical treatments are available. The cost to individuals and society of this undertreatment is substantial. Long suffering, suicide, occupational impairment, and impairment in interpersonal and family relationships exist. Efforts to redress this gap have included provider educational programs and public educational programs. Reasons for the continuing gap include patient, provider, and health care system factors. Patient-based reasons include failure to recognize the symptoms, underestimating the severity, limited access, reluctance to see a mental health care specialist due to stigma, noncompliance with treatment, and lack of health insurance. Provider factors include poor professional school education about depression, limited training in interpersonal skills, stigma, inadequate time to evaluate and treat depression, failure to consider psychotherapeutic approaches, and prescription of inadequate doses of antidepressant medication for inadequate durations. Mental health care systems create barriers to receiving optimal treatment. Strategies to narrow the gap include enhancing the role of patients and families as participants in care and advocates; developing performance standards for behavioral health care systems, including incentives for positive identification, assessment, and treatment of depression; enhancing educational programs for providers and the public; enhancing collaboration among provider subtypes (eg, primary care providers and mental health professionals); and conducting research on development and testing of new treatments for depression.

Classification of severity of health problems in family/general practice: an international field trial.

BACKGROUND: A methodology is needed for classification of health problems by severity. OBJECTIVES: We aimed to test the Duke Severity of Illness Checklist (DUSOI) for feasibility and usefulness. METHOD: The DUSOI was field tested internationally by 22 family/general practitioners in 9 countries. RESULTS: The DUSOI was found to be feasible for rating severity of illness of health problems in family/general practice. The measure was shown to be clinically useful in older patients and those with chronic and more severe health problems. Variability of severity ratings was less within the same rater than between different raters (i.e. higher intrarater than interrater reliability). Clinical face validity was supported by the finding that DUSOI ratings classified patients with the same diagnosis and those with different diagnoses according to the severity differences that would be expected clinically. CONCLUSIONS: Although research is needed to improve reliability and to test validity further, the DUSOI was shown in the present study to be a methodology that is reasonable for consideration as an international classification of health problems by their severity in primary care patients.

Medical school policies for part-time faculty committed to full professional effort.

The need for information about medical schools' efforts to allow faculty who wish to remain fully academic but work less than full time has been growing steadily. Building on the AAMC's 1993-94 survey of faculty appointment and tenure policies, in 1994 the authors surveyed 102 U.S. and Canadian medical schools that had answered yes to the question, "Does the medical school provide for faculty who choose to work less than full-time but whose full professional effort is directed towards the institution?" Seventy-one U.S. and Canadian medical schools reported provisions for "full professional effort" (FPE) faculty, and 32 of these had developed specific procedures for such faculty. Other nomenclatures in use for FPE faculty include "limited full-time," "full status/partial load," and "reduced period of responsibility." Almost half of the 71 survey respondents reported that FPE faculty could be appointed to, or remain on, a tenure track; more than half of these schools said that they lengthened the probationary period on a prorated basis. Women, much more frequently than men, had chosen the FPE option, especially women clinical faculty. While FPE faculty face more challenges than full-time faculty in accomplishing the tasks necessary for promotion in academic medicine, well-structured FPE options can benefit not only individual faculty members and their families but also the institution, which retains the commitment of valued faculty members seeking flexibility.

Age, seasonality and health.

Seasonal effects on mood and other components of functional status have been demonstrated in large segments of the general population but have received little attention in primary care patients. In the present study on adult members of a communal settlement (kibbutz) in Israel, seasonality and functional status were measured in both the winter and summer seasons in the same patients. Patients under age 65 had better overall health ratings than those 65 and over in both winter and summer. Overall health ratings were better in summer for those under 65 but were unchanged in the older group. Summer and winter seasonality scores were more constant in the younger group than in the older patients. We conclude that both age and seasonality need to be considered when measuring functional status in primary care patients.

Depressive disorders in three primary care populations: United States, Israel, Japan.

Primary care patients in the United States, Israel and Japan received the Inventory to Diagnose Depression and the Dartmouth COOP Functional Status Charts modified for international use. Patients were classified as having major depressive disorder or minor depression. Although demographic characteristics varied by country, the rank order and frequency of the depressive symptoms were similar for both major and minor depression. Functional impairment was most severe in patients with major depression, less severe in those with minor depression and was least impaired in those not depressed. The results suggest that depressive disorders have similar presentations in the three countries studied, although the separate cultures confer different consequences on patients receiving these diagnoses.
