What physicians need to know about seniors and limited prescription benefits, and why.

More and more often, seniors are faced with outpatient prescription benefits that have annual spending limits, and they may be forced to cut back on use of medications when they run out of benefits before the end of the year. Family physicians can play a valuable role by helping seniors choose the best value medications for their budgets and by checking whether or not seniors can afford their prescriptions.

A preliminary taxonomy of medical errors in family practice.

OBJECTIVE: To develop a preliminary taxonomy of primary care medical errors. DESIGN: Qualitative analysis to identify categories of error reported during a randomized controlled trial of computer and paper reporting methods. SETTING: The National Network for Family Practice and Primary Care Research. PARTICIPANTS: Family physicians. MAIN OUTCOME MEASURES: Medical error category, context, and consequence. RESULTS: Forty two physicians made 344 reports: 284 (82.6%) arose from healthcare systems dysfunction; 46 (13.4%) were errors due to gaps in knowledge or skills; and 14 (4.1%) were reports of adverse events, not errors. The main subcategories were: administrative failure (102; 30.9% of errors), investigation failures (82; 24.8%), treatment delivery lapses (76; 23.0%), miscommunication (19; 5.8%), payment systems problems (4; 1.2%), error in the execution of a clinical task (19; 5.8%), wrong treatment decision (14; 4.2%), and wrong diagnosis (13; 3.9%). Most reports were of errors that were recognized and occurred in reporters' practices. Affected patients ranged in age from 8 months to 100 years, were of both sexes, and represented all major US ethnic groups. Almost half the reports were of events which had adverse consequences. Ten errors resulted in patients being admitted to hospital and one patient died. CONCLUSIONS: This medical error taxonomy, developed from self-reports of errors observed by family physicians during their routine clinical practice, emphasizes problems in healthcare processes and acknowledges medical errors arising from shortfalls in clinical knowledge and skills. Patient safety strategies with most effect in primary care settings need to be broader than the current focus on medication errors.

Uncoordinated growth of the primary care work force.

Family physicians, nurse practitioners and physician assistants are distinctly different in their clinical training, yet they function interdependently. Together, they represent a significant portion of the primary care work force. Training capacity for these professions has increased rapidly over the physician assistant decade, but almost no collaborative work force planning has occurred.

NHBPEP report on high blood pressure in pregnancy: a summary for family physicians.

The National High Blood Pressure Education Program's Working Group on High Blood Pressure in Pregnancy recently issued a report implicating hypertension as a complication in 6 to 8 percent of pregnancies. Hypertension in pregnancy is related to one of four conditions: (1) chronic hypertension that predates pregnancy; (2) preeclampsia-eclampsia, a serious, systemic syndrome of elevated blood pressure, proteinuria and other findings; (3) chronic hypertension with superimposed preeclampsia; and (4) gestational hypertension, or nonproteinuric hypertension of pregnancy. Edema is no longer a criterion for preeclampsia, and the definition of blood pressure elevation is 140/90 mm Hg or higher. Patients with gestational hypertension have previously unrecognized chronic hypertension, emerging preeclampsia or transient hypertension of pregnancy, an obstetrically benign condition. Because distinguishing among these conditions can be done only in retrospect, clinical management of gestational hypertension consists of repeated evaluations to look for signs of emerging preeclampsia. Women with chronic hypertension should be followed for evidence of fetal growth restriction or superimposed preeclampsia. Management options for chronic hypertension in most women include discontinuing antihypertensive medications during pregnancy, switching to methyldopa or continuing previous antihypertensive therapy.

Direct graduate medical education payments to teaching hospitals by Medicare: unexplained variation and public policy contradictions.

PURPOSE: To comprehensively examine both inter- and intrastate variations in Medicare's cost-rate structure for teaching hospitals and to assess the Medicare payment system for graduate medical education (GME), as presently configured, as an instrument to promote physician workforce reform, specifically sufficient public access to primary care physician services. METHOD: Using Public Use Files of hospital cost reports from the Health Care Financing Administration for fiscal year 1997, 648 hospitals that met inclusion criteria for moderate GME volume were identified. The average and range of direct costs of resident training were computed for these teaching hospitals to illustrate differences within and between the 45 states that had at least two teaching hospitals that qualified for comparison. The cost rate upon which direct medical education (DME) payments are based was then correlated with the percentage of a state's counties that were wholly designated primary care health personnel shortage areas (PCHPSAs) in 1997 and with its primary care physician-to-population ratio, as determined from the Area Resource FILE: RESULTS: Variations in inter- and intrastate DME costs exist. In some states, the range in DME rates substantially exceeded the mean cost. DME funding policies are more generous toward teaching hospitals in states with greater primary care physician-to-population ratios and smaller proportions of counties wholly designated PCHPSAS: CONCLUSION: Inherent inequities in DME funding seriously undermine the current Medicare GME payment system's capacity to contribute to U.S. physician workforce reform and to improve access to care. There is actually a financial incentive to train residents in areas in which there is relatively less need for their services.

Role conflicts of physicians and their family members: rules but no rulebook.

OBJECTIVES: To elucidate the difficulties physicians have when a family member becomes ill and to elicit their underlying causes. DESIGN: Using a key informant technique, we solicited chairs of family medicine departments for their experiences with the health care provided to seriously ill family members. We then conducted in-depth, semistructured telephone interviews that were then transcribed, coded, and labeled for themes. SUBJECTS: 8 senior family physicians whose parents had experienced a serious illness within the past 5 years. All of the subjects reflected on experiences stemming from their fathers' illness. RESULTS: These physicians faced competing expectations: at an internal level, those of their ideal role in their family and their ideal professional identity; and at an external level, those originating from other family members and from other physicians. Reconciling these conflicting expectations was made more difficult by what they deemed to be suboptimal circumstances of the modern health care system. CONCLUSIONS: Conflicting rules of appropriate conduct, compounded by the inadequacies of modern health care, make the role of physician-family member especially challenging. The medical profession needs a clearer, more trenchant understanding of this role.

Hispanic versus white, non-Hispanic physician medical practices in Colorado.

The purpose of the study was to extend the scope of earlier research on minority physicians attending to the needs of the poor and their own ethnicity by contrasting practice characteristics of Hispanic doctors in Colorado with those of their white, non-Hispanic counterparts. It was found that Hispanic physicians spent more hours per week in direct patient care, were more likely to have a primary care specialty, and were less often specialty board certified than white, non-Hispanic doctors. Hispanic generalists established practices in areas in which the percentages of the population that were (1) below poverty level, (2) Hispanic, (3) Hispanic and below poverty level, and (4) white, non-Hispanic, and below poverty level were greater than in areas in which white, non-Hispanic primary care physicians practiced. These findings argue for special provision to admit ethnic minorities to undergraduate and graduate medical education programs.

Family physicians' personal experiences of their fathers' health care.

OBJECTIVES: The American health care system is complicated and can be difficult to navigate. The physician who observes the care of a family member has a uniquely informed perspective on this system. We hoped to gain insight into some of the shortcomings of the health care system from the personal experiences of physician family members. STUDY DESIGN: Using a key informant technique, we invited by E-mail any of the chairpersons of US academic departments of family medicine to describe their recent personal experiences with the health care system when their parent was seriously ill. In-depth semi-structured telephone interviews were conducted with each of the study participants. The interviews were transcribed, coded, and labeled for themes. POPULATION: Eight family physicians responded to the E-mail, and each was interviewed. These physicians had been in practice for an average of 19 years, were nationally distributed, and included both men and women. Each discussed their father's experience. RESULTS: All participants spoke of the importance of an advocate for their fathers who would coordinate medical care. These physicians witnessed various obstacles in their fathers's care, such as poor communication and fragmented care. As a result, many of them felt compelled to intervene in their fathers' care. The physicians expressed concern about the care their fathers received, believing that the system does not operate the way it should. CONCLUSIONS: Even patients with a knowledgeable physician family member face challenges in receiving optimal medical care. Patients might receive better care if health care systems reinforced the role of an accountable attending physician, encouraged continuity of care, and emphasized the value of knowing the patient as a person.

Seeing is believing: non-invasive, quantitative and repetitive imaging of reporter gene expression in living animals, using positron emission tomography.

The ability to monitor reporter gene expression in living animals and in patients will permit longitudinal examinations both of somatically transferred DNA in experimental animals and patients and of transgenic constructs expressed in experimental animals. If investigators can non-invasively monitor the organ and tissue specificity, the magnitude and the duration of gene expression from somatically transferred DNA and from transgenes, conceptually new experimental paradigms will be possible. If clinicians can non-invasively monitor the location, extent and duration of somatically transferred genes, they will be better able to determine the correlations between expression of therapeutic genes and clinical outcomes. We have developed two reporter gene systems for in vivo reporter gene imaging in which the protein products of the reporter genes sequester positron-emitting reporter probes. The "PET reporter gene" dependent sequestration of the "PET reporter probes" is subsequently measured in living animals by Positron Emission Tomography (PET). We describe here the principles of PET reporter gene/PET reporter probe in vivo imaging, the development of two imaging systems, and the validation of their ability to non-invasively, quantitatively and repetitively image reporter gene expression in murine viral gene transfer and transgenic models.
