Abstract
While pharmaceutical industry involvement in producing, interpreting, and regulating medical knowledge and practice is widely accepted and believed to promote medical innovation, industry-favouring biases may result in prioritizing corporate profit above public health. Using diabetes as our example, we review successive changes over forty years in screening, diagnosis, and treatment guidelines for type 2 diabetes and prediabetes, which have dramatically expanded the population prescribed diabetes drugs, generating a billion-dollar market. We argue that these guideline recommendations have emerged under pervasive industry influence and persisted, despite weak evidence for their health benefits and indications of serious adverse effects associated with many of the drugs they recommend. We consider pharmaceutical industry conflicts of interest in some of the research and publications supporting these revisions, and in related standard-setting committees and oversight panels. We raise concern over the long-term impact of these multifaceted involvements. Rather than accept industry conflicts of interest as normal, needing only to be monitored and managed, we suggest challenging that normalcy, and ask: what are the real costs of tolerating such industry participation? We urge the development of a broader focus to fully understand and curtail the systemic nature of industry's influence over medical knowledge and practice.

Abstract
As large corporations come to dominate U.S. health care, clinical medicine is increasingly market-driven and governed by business principles. We examine ways in which health insurers and health care systems are transforming the goals and means of clinical practice. Based on ethnographic research of diabetes management in a large health care system, we argue that together these organizations redefine clinical care in terms that prioritize financial goals and managerial logics, above the needs of individual patients. We demonstrate how emphasis on quality metrics reduces clinical work to quantifiable outcomes, redefining diabetes management to be the pursuit of narrowly defined goal numbers, despite often serious health consequences of treatment. As corporate employees, clinicians are compelled to pursue goal numbers by the heavy emphasis payers and health systems place on quality metrics, and accessing the required medications becomes the central focus of clinical practice.

Abstract
Background Task‐sharing in surgery is well established, with associate clinicians performing successful surgery in many countries. Little is known about the process of surgical skill acquisition by associate clinicians, or whether this differs from that of doctors. Methods A blinded experimental study compared surgical skill acquisition by Sierra Leonean associate clinicians enrolled in an essential and emergency surgery training programme with that of a matched group of UK surgical trainees. After identical instruction, practice time and with identities disguised, trainees were videoed performing simulated surgery. Trainees were marked on 12 performance parameters and five behaviour characteristics using validated tools and qualitative comment. Results The Sierra Leonean group comprised 19 associate clinicians and one doctor; the UK group comprised 20 doctors in their first 5 years of training. The UK group had significantly more surgical and postgraduate experience than the Sierra Leonean group. The Sierra Leonean trainees outperformed the UK trainees on three of the 12 performance parameters and four of the five behaviour characteristics. UK trainees did not outperform Sierra Leonean trainees on any parameter or characteristic. Qualitative differences in learning style were observed. Conclusion Sierra Leonean associate clinicians demonstrated equal or superior skill in all objective parameters tested, despite having less experience than the UK doctors.

Abstract
Racial/ethnic identity is contingent and arbitrary, yet it is commonly used to evaluate disease risk and treatment response. Drawing on open-ended interviews with patients and clinicians in two US clinics, we explore how racialized risk is conceptualized and how it impacts patient care and experience. We found that racial/ethnic risk was a common but poorly defined construct for both patients and clinicians, who intermingled concepts of genetics, biology, behavior, and culture, while disregarding historical or structural context. We argue that racializing risk embodies social power in marked and unmarked bodies, reinforcing inequality along racial lines and undermining equitable health care.

Abstract
With rapid consolidation of American medicine into large-scale corporations, corporate strategies are coming to the forefront in health care delivery, requiring a dramatic increase in the amount and detail of documentation, implemented through use of electronic health records (EHRs). EHRs are structured to prioritize the interests of a myriad of political and corporate stakeholders, resulting in a complex, multi-layered, and cumbersome health records system, largely not directly relevant to clinical care. Drawing on observations conducted in outpatient specialty clinics, we consider how EHRs prioritize institutional needs manifested as a long list of requisites that must be documented with each consultation. We argue that the EHR enforces the centrality of market principles in clinical medicine, redefining the clinician's role to be less of a medical expert and more of an administrative bureaucrat, and transforming the patient into a digital entity with standardized conditions, treatments, and goals, without a personal narrative.

Abstract
Under the Affordable Care Act, Medicaid Expansion programs are extending Medicaid eligibility and increasing access to care. However, stigma associated with public insurance coverage may importantly affect the nature and content of the health care beneficiaries receive. In this paper, we examine the health care stigma experiences described by a group of low-income public insurance beneficiaries. They perceive stigma as manifest in poor quality care and negative interpersonal interactions in the health care setting. Using an intersectional approach, we found that the stigma of public insurance was compounded with other sources of stigma including socioeconomic status, race, gender, and illness status. Experiences of stigma had important implications for how subjects evaluated the quality of care, their decisions impacting continuity of care, and their reported ability to access health care. We argue that stigma challenges the quality of care provided under public insurance and is thus a public health issue that should be addressed in Medicaid policy.

Abstract
Medicaid expansion, a key part of the Affordable Care Act, has been opposed by conservative politicians despite its fiscal and public health benefits. In response, some Republican-led states have expanded Medicaid with new reforms, including requirements for cost sharing and behavioral incentives, that promote conservative political values tied to an ideology of personal responsibility. We examine this trend using Michigan's Medicaid expansion as a case example. We explore the origins, evidence base, and possible consequences of these reforms. We argue that these reforms prioritize ideology over sound public health knowledge, deflecting attention away from the social, economic, and structural factors that influence the health of the poor, and may ultimately contribute to counterproductive public health and fiscal outcomes.

Abstract
Introduction The mortality and morbidity of Ebola extends far wider than those contracting the disease. Surgical activity in Sierra Leone has been severely disrupted by the epidemic. Method This is a retrospective study examining the effect of the 2014–2015 Ebola virus epidemic on surgical activity in a Sierra Leone’s main teaching hospital. Results The impact of national and local events on surgical provision is illustrated by the experience of Connaught Hospital, Freetown Sierra Leone. Surgical activity fell dramatically in August 2014, the month when the most health care workers died and continued to fall to just 3% of expected activity. Two of eight surgeons at Connaught Hospital died of Ebola. Discussion The example of Connaught Hospital serves as a graphic and poignant illustration of the difficulties faced by surgeons in low resource settings when dealing with the acute effects of a natural disaster. In any future epidemic, high levels of preparedness, training and protection, in addition to liaison with public health teams early in an epidemic, may allow surgeons to carry out at least some of their duties without the very high levels of personal risk seen here. In a country with so few specialists the loss of 25% is disastrous and will result in long term capacity reduction.

Abstract
Preventive health care has become prominent in clinical medicine in the US, emphasising risk assessment and control, rather than addressing the signs and symptoms of pathology. Current clinical guidelines, reinforced by evidence-based decision aids and quality of care assessment, encourage clinicians to focus on maintaining rigid test thresholds that are based on population norms. While achieving these goals may benefit the total population, this may be of no benefit or even harmful to individual patients. In order to explore how this phenomenon is manifested in clinical care and consider some factors that promote and sustain this trend, we analysed observations of over 100 clinical consultations, and open-ended interviews with 58 primary care clinicians and 70 of their patients. Both clinicians and patients equated at-risk states with illness and viewed the associated interventions not as prevention, but as treatment. This conflation of risk and disease redefines clinical success such that reducing the threat of anticipated future illness requires the acceptance of aggressive treatments and any associated adverse effects in the present. While the expanding emphasis on preventive medicine may improve the health profile of the total population, the implications of these innovations for the wellbeing of individual patients merits careful reconsideration.

Abstract
Race, although an unscientific concept, remains prominent in health research and clinical guidelines, and is routinely invoked in clinical practice. In interviews with 58 primary care clinicians we explored how they understand and apply concepts of racial difference. We found wide agreement that race is important to consider in clinical care. They explained the effect of race on health, drawing on common assumptions about the biological, class, and cultural characteristics of racial minorities. They identified specific race-based clinical strategies for only a handful of conditions and were inconsistent in the details of what they said should be done for minority patients. We conclude that using race in clinical medicine promotes and maintains the illusion of inherent racial differences and may result in minority patients receiving care aimed at presumed racial group characteristics, rather than care selected as specifically appropriate for them as individuals.

Abstract
Many anticipate that expanding knowledge of genetic variations associated with disease risk and medication response will revolutionize clinical medicine, making possible genetically based Personalized Medicine where health care can be tailored to individuals, based on their genome scans. Pharmacogenetics has received especially strong interest, with many pharmaceutical developers avidly working to identify genetic variations associated with individual differences in drug response. While clinical applications of emerging genetic knowledge are becoming increasingly available, genetic tests for drug selection are not as yet widely accessible, and many primary care clinicians are unprepared to interpret genetic information. We conducted interviews with 58 primary care clinicians, exploring how they integrate emerging pharmacogenetic concepts into their practices. We found that in their current practices, pharmacogenetic innovations have not led to individually tailored treatment, but instead have encouraged use of essentialized racial/ethnic identity as a proxy for genetic heritage. Current manifestations of Personalized Medicine appear to be reinforcing entrenched notions of inherent biological differences between racial groups, and promoting the belief that racial profiling in health care is supported by cutting-edge scientific authority. Our findings raise concern for how pharmacogenetic innovations will actually affect diverse populations, and how unbiased treatment can be assured.

Abstract
Low-income Hispanics are often identified as especially at risk for common chronic conditions like diabetes, and targeted for aggressive screening and treatment. Anthropologists and other social scientists have extensively explored barriers and facilitators to chronic illnesses management in minority populations, but have not yet considered the impact of recently lowered diagnostic and treatment thresholds on such groups. In this paper, we critically review recent changes in diabetes, hypertension and high cholesterol diagnostic and treatment standards which have dramatically increased the number of people being treated for these conditions. Drawing on an ethnographic study of chronic illness management in two Hispanic-serving clinics in the Midwest, we examine how these new standards are being applied, and consider the resulting health care challenges these Hispanic patients face. Our analysis leads us to question the value of promoting narrowly defined treatment goals, particularly when patients lack reliable access to the health care resources these goals require. While improving the health of low-income Hispanics is a worthwhile goal, it is important to consider whether these efforts may be promoting over-diagnosis and over-treatment, drawing them into an expensive chronic patient role with uncertain benefit.

Abstract
PURPOSE Recently, there has been dramatic increase in the diagnosis and pharmaceutical management of common chronic illnesses. Using qualitative data collected in primary care clinics, we assessed how these trends play out in clinical care. METHODS This qualitative study focused on management of type 2 diabetes and hypertension in 44 primary care clinics in Michigan and was based on interviews with 58 clinicians and 70 of their patients, and observations of 107 clinical consultations. We assessed clinicians' treatment strategies and discussions of factors influencing treatment decisions, and patients' understandings and experiences in managing these illnesses. RESULTS Clinicians focused on helping patients achieve test results recommended by national guidelines, and most reported combining 2 or more medications per condition to reach targets. Medication selection and management was the central focus of the consultations we observed. Polypharmacy was common among patients, with more than one-half taking 5 or more medications. Patient interviews indicated that heavy reliance on pharmaceuticals presents challenges to patient well-being, including financial costs and experiences of adverse health effects. CONCLUSIONS Factors promoting heavy use of pharmaceuticals include lower diagnostic and treatment thresholds, clinician-auditing and reward systems, and the prescribing cascade, whereby more medications are prescribed to control the effects of already-prescribed medications. We present a conceptual model, the inverse benefit law, to provide insight into the impact of pharmaceutical marketing efforts on the observed trends. We make recommendations about limiting the influence of the pharmaceutical industry on clinical practice, toward improving the well-being of patients with chronic illness.

Abstract
BACKGROUND Sacral nerve stimulation (SNS) is emerging as a potential treatment for patients with constipation. Although SNS can elicit an increase in colonic propagating sequences (PSs), the optimal stimulus parameters for this response remain unknown. This study evaluated the colonic motor response to subsensory and suprasensory SNS in patients with slow-transit constipation. METHODS Patients with confirmed slow-transit constipation were studied. Either a water-perfused manometry catheter or a high-resolution fibre-optic manometry catheter was positioned colonoscopically to the caecum. A temporary electrode was implanted transcutaneously in the S3 sacral nerve foramen. In the fasted state, three conditions were evaluated in a double-blind randomized fashion: sham, subsensory and suprasensory stimulation. Each 2-h treatment period was preceded by a 2-h basal period. The delta (Δ) value was calculated as the frequency of the event during stimulation minus that during the basal period. RESULTS Nine patients had readings taken with a water-perfused catheter and six with a fibre-optic catheter. Compared with sham stimulation, suprasensory stimulation caused a significant increase in the frequency of PSs (mean(s.d.) Δ value - 1·1(7·2) versus 6·1(4·0) PSs per 2 h; P = 0·004). No motor response was recorded in response to subsensory stimulation compared with sham stimulation. Compared with subsensory stimulation, stimulation at suprasensory levels caused a significant increase in the frequency of PSs (P = 0·006). CONCLUSION In patients with slow-transit constipation, suprasensory SNS increased the frequency of colonic PSs, whereas subsensory SNS stimulation did not. This has implications for the design of therapeutic trials and the clinical application of the device.

Abstract
UNLABELLED Racial and ethnic variables are common in research on variation in bone density. This literature review describes some of the common flaws associated with the use of these variables and provides some suggestions for how bone density research may be able to better document and address skeletal health disparities. INTRODUCTION Racial/ethnic differences in bone density have been commonly documented in the research literature. While effective identification of the specific factors underlying these trends might go a long way in informing treatment and screening for osteoporosis, this would require careful consideration of exactly what these variables are capturing. However, the basis and implications of what racial/ethnic variables represent have not carefully been examined in bone density research. METHODS For this paper, we systematically reviewed 55 articles that included bone density and race/ethnicity as key variables. Our analysis reveals that racial/ethnic terminology in these articles is highly variable, and discussion of how race/ethnicity is determined is often vague and idiosyncratic. Racial/ethnic variables are being used for a wide range of analytical purposes in statistical tests, which may not be appropriate for such a complex and poorly defined variable. RESULTS Many articles attribute racial/ethnic differences in bone mass/bone density to genetic causes, although few studies actually examine genetic data. CONCLUSION This analysis indicates that more rigorous examination of what race/ethnicity actually captures, more careful definitions of group labels and the procedures for assigning them, and attention to the limitations of how such variables can reliably be used in data analyses is needed to help address the problems and issues outlined in this review.

Abstract
BACKGROUND The morphology, motor responses and spatiotemporal organization among colonic propagating sequences (PS) have never been defined throughout the entire colon of patients with slow transit constipation (STC). Utilizing the technique of spatiotemporal mapping, we aimed to demonstrate 'manometric signatures' that may serve as biomarkers of the disorder. METHODS In 14 female patients with scintigraphically confirmed STC, and eight healthy female controls, a silicone catheter with 16 recording sites spanning the colon at 7.5 cm intervals was positioned colonoscopically with the tip clipped to the cecum. Intraluminal pressures were recorded for 24 h. KEY RESULTS Pan-colonic, 24 h, spatiotemporal mapping identified for the first time in STC patients: a marked paucity of propagating pressure waves in the midcolon (P = 0.01), as a consequence of a significant (P < 0.0001) decrease in extent of propagation of PS originating in the proximal colon; an increase in frequency of retrograde PS in the proximal colon; a significant reduction in the spatiotemporal organization among PS (P < 0.001); absence of the normal nocturnal suppression of PS. CONCLUSIONS & INFERENCES Pancolonic, 24 h, spatiotemporal pressure mapping readily identifies characteristic disorganization among consecutive PS, regions of diminished activity and absent or deficient fundamental motor patterns and responses to physiological stimuli. These features are all likely to be important in the pathophysiology of slow transit constipation.

Abstract
BACKGROUND The search for genetic variants between racial/ethnic groups to explain differential disease susceptibility and drug response has provoked sharp criticisms, challenging the appropriateness of using race/ethnicity as a variable in genetics research, because such categories are social constructs and not biological classifications. OBJECTIVES To gain insight into how a group of genetic scientists conceptualise and use racial/ethnic variables in their work and their strategies for managing the ethical issues and consequences of this practice. METHODS In-depth semi-structured interviews were conducted with a purposive sample of 30 genetic researchers who use racial/ethnic variables in their research. Standard qualitative methods of content analysis were used. RESULTS Most of the genetic researchers viewed racial/ethnic variables as arbitrary and very poorly defined, and in turn as scientifically inadequate. However, most defended their use, describing them as useful proxy variables on a road to "imminent medical progress". None had developed overt strategies for addressing these inadequacies, with many instead asserting that science will inevitably correct itself and saying that meanwhile researchers should "be careful" in the language chosen for reporting findings. CONCLUSIONS While the legitimacy and consequences of using racial/ethnic variables in genetics research has been widely criticised, ethical oversight is left to genetic researchers themselves. Given the general vagueness and imprecision we found amongst these researchers regarding their use of these variables, they do not seem well equipped for such an undertaking. It would seem imperative that research ethicist move forward to develop specific policies and practices to assure the scientific integrity of genetic research on biological differences between population groups.

Abstract
OBJECTIVE To examine the informed consent process when trained language interpreters are unavailable. BACKGROUND Ensuring sufficient patient understanding for informed consent is especially challenging for patients with Limited English Proficiency (LEP). While US law requires provision of competent translation for LEP patients, such services are commonly unavailable. DESIGN AND PARTICIPANTS Qualitative data was collected in 8 prenatal genetics clinics in Texas, including interviews and observations with 16 clinicians, and 30 Latina patients. Using content analysis techniques, we examined whether the basic criteria for informed consent (voluntariness, discussion of alternatives, adequate information, and competence) were evident for each of these patients, contrasting LEP patients with patients not needing an interpreter. We present case examples of difficulties related to each of these criteria, and compare informed consent scores for consultations requiring interpretation and those which did not. RESULTS We describe multiple communication problems related to the use of untrained interpreters, or reliance on clinicians' own limited Spanish. These LEP patients appear to be consistently disadvantaged in each of the criteria we examined, and informed consent scores were notably lower for consultations which occurred across a language barrier. CONCLUSIONS In the absence of adequate Spanish interpretation, it was uncertain whether these LEP patients were provided the quality and content of information needed to assure that they are genuinely informed. We offer some low-cost practice suggestions that might mitigate these problems, and improve the quality of language interpretation, which is essential to assuring informed choice in health care for LEP patients.

Abstract
Isosorbide and hydralazine in a fixed-dose combination (BiDil) has provoked controversy as the first drug approved by the Food and Drug Administration marketed for a single racial-ethnic group, African Americans, in the treatment of congestive heart failure. Family physicians will be better prepared to counsel their patients about this new drug if they understand a number of background issues. The scientific research leading to BiDil's approval tested the drug only in African American populations, apparently for commercial reasons, so the drug's efficacy in other populations is unknown. Race as a biological-medical construct is increasingly controversial; BiDil offers a good example of how sociocultural factors in disease causation may be overlooked as a result of an overly simplistic assumption of a racial and hence presumed genetic difference. Past discrimination and present disparities in health care involving African American patients are serious concerns, and we must welcome a treatment that promises to benefit a previously underserved group; yet the negative aspects of BiDil and the process that led to its discovery and marketing set an unfortunate precedent. Primary care physicians should be aware of possible generic equivalents that will affect the availability of this drug for low-income or uninsured patients.

Abstract
OBJECTIVE To determine whether Methenamine Hippurate (MH) or cranberry tablets prevent urinary tract infections (UTI) in people with neuropathic bladder following spinal cord injury (SCI). STUDY DESIGN Double-blind factorial-design randomized controlled trial (RCT) with 2 year recruitment period from November 2000 and 6 month follow-up. SETTING In total, 543 eligible predominantly community dwelling patients were invited to participate in the study, of whom 305 (56%) agreed. METHODS Eligible participants were people with SCI with neurogenic bladder and stable bladder management. All regimens were indistinguishable in appearance and taste. The dose of MH used was 1 g twice-daily. The dose of cranberry used was 800 mg twice-daily. The main outcome measure was the time to occurrence of a symptomatic UTI. RESULTS Multivariate analysis revealed that patients randomized to MH did not have a significantly longer UTI-free period compared to placebo (HR 0.96, 95% CI: 0.68-1.35, P=0.75). Patients randomized to cranberry likewise did not have significantly longer UTI-free period compared to placebo (HR 0.93, 95% CI: 0.67-1.31, P=0.70). CONCLUSION There is no benefit in the prevention of UTI from the addition of MH or cranberry tablets to the usual regimen of patients with neuropathic bladder following SCI.

Abstract
Risk modeling is an increasingly important part of clinical medicine; however, "risk status" is a complex notion, understood differently by patients and clinicians. Patients' ability to make informed choices about clinical procedures often requires that they interpret risk statistics, which may be difficult to understand and apply. In this article, which is based on a study of prenatal care in South Texas, we consider how notions of risk affect patient decisions about prenatal genetic testing. The term "risk" carries multiple meanings for clinicians and patients. These meanings may conflate concepts of danger and probability as well as muddle population risk and individual risk. We propose that failure to articulate the varied and contrasting meanings of risk held by clinicians and patients can undermine clinical communication and, thereby, hamper patients' ability to make autonomous, informed choices. Attending to these differences may prove useful in empowering patients to make truly informed decisions.

Abstract
PURPOSE Cultural competency is now a requirement in the curriculum of many health professions. However, clinicians' understandings of cultural difference, the accuracy of those understandings, and their impact on patient care have not yet been carefully explored. The authors conducted an ethnographic study designed to describe clinicians' views of Latino culture in the context of amniocentesis decision making, compared those to patients' discussions of their decision making, and explored how clinicians' views about culture are manifested in consultations with Latinas. METHOD Between 2000 and 2002, semistructured, open-ended interviews were conducted in southern Texas with convenience samples of 50 clinicians who discuss prenatal testing with patients, and 40 self-identified Latina patients who had been offered amniocentesis. Observations were also made of 101 genetic counseling sessions. Content analysis focused on the cultural characteristics clinicians identified as affecting Latinas' decision making, patients' self-reported decision-making processes, and clinician and patient comments and actions observed during genetics counseling sessions. RESULTS Most clinicians said Latinas are likely to decline amniocentesis because they are religious, fatalistic, male-dominated, family-centered, and superstitious. However, patients' discussions of their decision making were not consistent with these characterizations. Furthermore, clinicians reported providing less complete information to Latina patients in their efforts to be culturally sensitive. CONCLUSIONS Comparing patient and clinician interviews bring into question clinicians' notion of Latino culture's role in amniocentesis decision making. Efforts to be "culturally competent," in the absence of a patient-centered approach, may unintentionally encourage stereotyping, thereby negatively affecting the quality and content of clinical care.

Abstract
With the increasing technical sophistication of medicine, clinicians' task of assuring patient informed consent is increasingly elusive. Taking the example of prenatal genetic testing, we examine efforts to communicate the complexities of genetic knowledge and risk calculation to patients. In this qualitative, descriptive study, we interviewed 50 clinicians and 40 patients, and observed 101 genetic counseling sessions. We found the clinicians and patients have different goals, purposes, and values regarding testing, which affect their clinical interactions. The information the clinicians provide patients reflects their clinical interest in identifying and controlling pathophysiology, while patients, in contrast, are most concerned with protecting and nurturing their pregnancy. We argue informed patient decision-making about prenatal testing options requires information that is responsive to patient interests. We recommend developing a shared decision-making approach, to facilitate the full participation of both clinicians and patients in the decision-making process.

Abstract
Acculturation has become a popular variable in research on health disparities among certain ethnic minorities, in the absence of serious reflection about its central concepts and assumptions. Key constructs such as what constitutes a culture, which traits pertain to the ethnic versus "mainstream" culture, and what cultural adaptation entails have not been carefully defined. Using examples from a systematic review of recent articles, this paper critically reviews the development and application of the concept of acculturation in US health research on Hispanics. Multiple misconceptions and errors in the central assumptions underlying the concept of acculturation are examined, and it is concluded that acculturation as a variable in health research may be based more on ethnic stereotyping than on objective representations of cultural difference.

Abstract
Alleviating health disparities in the United States is a goal with broad support. Medical research undertaken to achieve this goal typically adopts the well-established perspective that racial discrimination and poverty are the major contributors to unequal health status. However, the suggestion is increasingly made that genetic research also has a significant role to play in alleviating this problem, which likely overstates the importance of genetics as a factor in health disparities. Overemphasis on genetics as a major explanatory factor in health disparities could lead researchers to miss factors that contribute to disparities more substantially and may also reinforce racial stereotyping, which may contribute to disparities in the first place. Arguments that promote genetics research as a way to help alleviate health disparities are augmented by several factors, including research funding initiatives and the distinct demographic patterns of health disparities in the United States.

Abstract
PURPOSE The loss of patients to follow-up for abnormal findings from Pap screenings is an important public health concern, particularly among poor and minority women. This study explores factors affecting incomplete follow-up among a group of Hispanic women with low incomes. DESCRIPTION OF STUDY A qualitative descriptive study was conducted of 11 Hispanic patients with incomplete Pap smear follow-up at a public clinic in a major city in south Texas. Patients were interviewed using a semistructured, open-ended schedule of questions, and their medical records were abstracted. The clinic's five staff members also were interviewed. Comparative chronologies were constructed for each case, contrasting patient and staff accounts of the same set of events. All data were coded by at least two investigators. RESULTS All study patients had mildly abnormal Pap smear results and had not met the follow-up criteria, but all understood and were committed to Pap screening. Although viewed by staff as noncompliant, none of the patients viewed her behavior this way. This staff-patient discrepancy was attributable to poor communication, mixed messages, clinic errors, and, perhaps most importantly, to a conflict between program policies and the specific circumstances of individual cases. Two case examples are presented to illustrate key points. CLINICAL IMPLICATIONS Strategies that may help to reduce loss to follow-up among similar patients include the following: allowing clinic staff more flexibility in follow-up procedures for women who have consistently normal follow-up tests, including Spanish translations of written messages; enlisting patients' agreement in setting appointments; and updating patient records to reflect follow-up care that had been received in other clinics.

Abstract
This study was designed to better understand how women in a developing region choose between the multiple options available to them for birthing. We conducted focused, open-ended ethnographic interviews with 38 nonindigenous, economically marginal women in Chiapas, Mexico. We found that although medical services for birthing were readily available to them, these women most often chose traditional birth attendants (TBAs) for assistance with their births. They expressed a clear preference for TBAs in the case of a normal birth, but viewed medical services as useful for diagnosing and managing problem deliveries and for tubal ligations. They favored TBAs because they valued being able to choose birthing locations and birthing positions and to have relatives present during the birth, all features they must give up for medically attended births in this region.

Abstract
BACKGROUND Specialized methods are necessary to collect data from migrant farmworkers for epidemiologic research. METHODS We developed a questionnaire that collected lifetime occupational histories and other lifestyle risk factors via a life events/icon calendar, and administered the questionnaire to a convenience sample of 162 migrant farmworkers in nine areas of the U.S. RESULTS The average duration of the interviews was about 1 h 30 min, with an average of 45 min for the work history section. The occupational histories covered a median of 27.6 years per person for men and 20.8 years per person for women. The median number of years spent in farm jobs was 11.3 for men and 5.8 for women. The median number of farm jobs (crop/task combination) per person was 59 among men and 27 among women. Many farmworkers performed the same crop/task combinations at multiple times throughout their lives, yielding a median of 13 unique farm jobs and 8 unique crops among men and 7 jobs and 5 crops among women. CONCLUSIONS The project demonstrated that it is feasible to collect detailed work histories and other risk factor data from farmworkers, documented the complexity of work histories encountered among farmworkers, and yielded recommendations for refining a questionnaire that will facilitate future epidemiologic research on farmworkers.

Abstract
Medical anthropologists involved in clinical research are often asked to help explain patients' "noncompliance" with treatment recommendations. The clinical literature on "noncompliance" tends to problematize only the patient's perspective, treating the provider's perspective as an uncontroversial point of departure. Explicating the articulation between provider and patient assumptions, expectations, and perceptions in managing chronic illness is an area well suited to the unique perspective of medical anthropologists. In this article we present an analytical framework for contrasting patient and provider goals, strategies, and evaluation criteria in chronic illness management, using examples from research on type 2 diabetes care in South Texas. This approach goes beyond contrasting patient and provider concepts and explanations of the illness itself and examines their contrasting views within the dynamic process of long-term care. This approach may prove especially useful for research aimed at a clinical audience, since it maintains a clinically relevant focus while giving serious consideration to the patient's perspective.

Abstract
PURPOSE This study assessed the extent to which community-dwelling rural older adults mismanage their prescription medication regimens and predicted mismanagement of medications from selected socioeconomic, health status, and medication profile characteristics. DESIGN AND METHODS Personal interviews with 499 community-dwelling adults aged 66 and over taking at least one prescription medication and living in a rural region of the Southeast. With approximately equal numbers of African American and white men and women, the SUDAAN multiple logistic regression procedure was used to predict the mismanagement of prescription medications. RESULTS The mismanagement of prescribed medication regimens is relatively common among older adults. Those more likely than others to mismanage their regimens are African American, younger, in poorer mental health, with more acute care physician visits, and those who find payment for their medications to be problematic. IMPLICATIONS The implications of the findings for what is known about the self-modification of drug regimens, targeting prescription drug cost benefits or interventions, and the limitations of the study are discussed.

Abstract
BACKGROUND Clinicians are often concerned that use of alternative treatments by Mexican American patients with diabetes competes with medical treatment. We examined the use and evaluation of alternative treatments for diabetes by a sample of these patients. METHODS Following a descriptive qualitative design, a convenience sample of 43 low-income Mexican Americans with type 2 diabetes were interviewed. We analyzed interview transcripts for alternative treatments named, patterns of use, evaluation of those treatments, and the use of biomedical approaches. We crosschecked the results for interrater reliability. RESULTS Herbs were mentioned as possible alternative treatments for diabetes by 84% of the patients interviewed. However, most had never or rarely tried herbs and viewed them as supplemental to medical treatments. Most said prayer influences health by reducing stress and bringing healing power to medicines. None used curanderos (traditional healers) for diabetes. Most actively used biomedical treatments and were less actively involved in alternative approaches. Statistical tests of association showed no competition between biomedical and alternative treatments, and alternative treatment activity tended to be significantly lower than biomedical. Most study participants emphasized medical treatment and only used alternative treatments as secondary strategies. Those patients very actively using alternative approaches also tended to be very actively using biomedical methods; they were using all resources they encountered. CONCLUSIONS Traditional attitudes and beliefs were not especially important to the patients in this study and presented no barriers to medical care. For these patients, it also cannot be assumed that belief in alternative treatments and God's intervention indicate fatalism or noncompliance but instead require consideration of individual treatment behaviors.

Abstract
Studies of self-care behaviors in the management of type 2 diabetes often focus on patient knowledge and motivation, without considering the role of practitioner orientations. Using an exploratory descriptive design, we conducted open-ended interviews with 51 type 2 diabetes patients and 35 practitioners from clinics in San Antonio and Laredo, Texas. We found critical differences between patient and practitioner goals, evaluations, and strategies in diabetes management, especially regarding such key concepts as "control" and "taking care of self". Practitioners' perspectives are rooted in a clinical context, emphasizing technical considerations, whereas patients' perspectives exist within a life-world context and foreground practical and experiential considerations. These result in very different approaches to treatment. Practitioners, presuming failed treatment indicates uncooperativeness, try to inform and motivate patients. The patients we interviewed, however, understood and were committed to type 2 diabetes self-care, but lacked full access to behavioral options due to their poverty and limited social power.

Abstract
PURPOSE/OBJECTIVES To understand impediments to receiving and reporting timely follow-up care for abnormal Pap tests among Hispanic women. DESIGN Descriptive, qualitative. SETTING A federally funded cancer screening clinic in urban South Texas. SAMPLE 11 Mexican/Mexican-American women over 40 years old who appear in clinic records as "lapsed" in follow-up and 5 clinic staff members. METHODS Semistructured, qualitative interviews regarding staff and patient concepts about cancer, cancer screening, and follow-up. Abstraction of patients' clinic charts. MAIN RESEARCH VARIABLES Factors associated with women being classified as "lapsed" in follow-up care for abnormal Pap tests. FINDINGS Only two patients had no follow-up, while nine eventually had follow-up, either elsewhere or after several missed appointments. Contrary to expectations, poor knowledge, lack of social support, and lack of availability of care were not factors impeding follow-up. Reluctance to be examined by a male practitioner, lack of flexibility in scheduling clinic appointments, and poor staff communication regarding appointments and the seriousness of the condition were all influences negatively affecting follow-up behavior. Nevertheless, these women went to significant lengths to comply with follow-up recommendations. CONCLUSIONS The classification of patients' follow-up behavior as "lapsed" was not attributable to culturally based beliefs and attitudes, nor lack of knowledge and motivation, but was primarily the result of institutional features such as scheduling and record-keeping practices and policies. IMPLICATIONS FOR NURSING PRACTICE More thorough evaluation of actual behaviors would ensure more accurate assessment of follow-up behavior in this group. More female practitioners, better communication of appointments and of the seriousness of the condition, and more flexible scheduling options would reduce the difficulty these Hispanic patients encountered in having timely follow-up care.

Abstract
Moral themes were a striking feature of the causal explanations for female cancers discussed by oncologists and patients in an ethnographic study of hospital-based cancer care in southern Mexico. These explanations integrate general biomedical explanations with everyday expectations and experiences, giving meaning to otherwise arbitrary events. Analysis of case examples shows that causal models incorporate local constructs about what constitutes a virtuous life, especially in terms of class-and gender-based values. Although patients and physicians draw on similar concepts of moral order, they apply these constructs in distinct ways. Because physicians' explanations are necessarily framed in terms of object, their causal stories employ generalized presumptions about how categories of persons behave (e.g., women, the lower class). In contrast, patients' explanations are framed in terms of subject; they are based on the specific details of their personal history. The article examines the distinct perspectives of physicians and patients, and provides an illustration of how biomedical culture articulates with the local moral constructs of a particular community.

Abstract
The management of 63 patients diagnosed by surgeons as having sexually transmitted disease (STD) was audited. A diagnosis of STD was made in 51 (81%) of patients without taking a sexual history. Only 2 (3%) patients were referred to genitourinary medicine (GUM). Appropriate microbiological specimens were obtained from only two of 52 (4%) patients diagnosed with either pelvic inflammatory disease (PID) or epididymo-orchitis. Reliance was placed on inappropriate specimens in 22 (42%). There was widespread use of inappropriate antibiotics. The management of sexually transmitted disease by surgeons was very poor. These patients should all be referred to genito-urinary medicine.

Abstract
This paper reports findings from an ethnographic study of self-care behaviors and illness concepts among Mexican-American non-insulin dependent diabetes mellitus (NIDDM) patients. Open-ended interviews were conducted with 49 NIDDM patients from two public hospital outpatient clinics in South Texas. They are self-identified Mexican-Americans who have had NIDDM for at least 1 yr, and have no major impairment due to NIDDM. Interviews focused on their concepts and experiences in managing their illness and their self-care behaviors. Clinical assessment of their glucose control was also extracted from their medical records. The texts of patient interviews were content analyzed through building and refining thematic matrixes focusing on their causal explanations and treatment behaviors. We found patients' causal explanations of their illness often are driven by an effort to connect the illness in a direct and specific way to their personal history and their past experience with treatments. While most cite biomedically accepted causes such as heredity and diet, they elaborate these concepts into personally relevant constructs by citing Provoking Factors, such as behaviors or events. Their causal models are thus both specific to their personal history and consistent with their experiences with treatment success or failure. Based on these findings, we raise a critique of the Locus of Control Model of treatment behavior prevalent in the diabetes education literature. Our analysis suggests that a sense that one's own behavior is important to the disease onset may reflect patients' evaluation of their experience with treatment outcomes, rather than determining their level of activity in treatment.

Abstract
BACKGROUND Our study explored behavioral factors affecting what patients with type 2 diabetes do for self-care and why they do it. The findings were used to develop clinical recommendations to improve intervention strategies. METHODS Interviewers, using open-ended questions, explored patients' own perceptions and assessments of self-care behaviors. The fifty-one subjects were self-identified Mexican Americans who had type 2 diabetes for at least 6 months, and had no major impairment as a result of this diabetes. Texts of patient interviews were analyzed by building and refining matrixes to display and compare central themes regarding treatment strategies and their contexts. RESULTS All patients were trying to control their diabetes, but none of them followed recommendations completely. Instead, they adapted self-care behaviors to the exigencies of everyday life. Key factors influencing patients' treatment choices were: (1) the belief in the power of modern medicine; (2) the desire to act and feel "normal"; (3) the desire to avoid physical symptoms; and (4) limited economic resources. CONCLUSIONS As patients apply treatment recommendations in the context of their everyday lives, they continually must make many small decisions affecting self-care behavior. The specific contexts of patients' lives, including their economic, educational, and cultural circumstances, determine how the generalized principles of type 2 diabetes management are implemented. Clinical strategies must be responsive to these circumstances in order to enable patients to make appropriate decisions when adapting their self-care behaviors to their own situations.

Abstract
BACKGROUND The risk of colorectal cancer is higher among relatives of those affected. The neoplastic yield reported from screening such individuals varies enormously between studies and depends on the age and strength of the family history of those screened. AIMS To ascertain the neoplastic yield of endoscopic screening of first degree relatives of patients with colorectal cancer by age and familial risk. SUBJECTS A total of 330 individuals with a family history of colorectal cancer. METHOD Endoscopic screening conducted according to a protocol. RESULTS Adenomas were found in 12%, and adenomas larger than 1 cm in 8%, of "high risk" individuals screened primarily by colonoscopy. Of those with neoplasia, 26% had lesions at or proximal to the splenic flexure. Neoplasia was found in 9.5% of individuals at lower familial risk, screened primarily by 60 cm flexible sigmoidoscopy, 4% of whom had neoplasia larger than 1 cm in size or cancer. Neoplastic yield was greatest in the fourth and fifth decades in those at highest risk, but increased with age in those at lower risk. CONCLUSIONS For individuals with two or more first degree relatives, or relatives who have developed colorectal cancer at a young age, colonoscopy appears to be the only satisfactory method of screening, but 60 cm flexible sigmoidoscopy may be useful in those at lower levels of risk.

Abstract
OBJECTIVE This study examines NIDDM patients' attitudes toward insulin injections, the basis of these attitudes, and how they may affect patients' willingness to take insulin. RESEARCH DESIGN AND METHODS Forty-four low-income Mexican American NIDDM patients were interviewed using open-ended in-depth interviewing techniques. Transcripts were analyzed using techniques of content analysis. Data classification was cross-checked in analysis conferences and through a second researcher coding 50% of the cases, comparing the results, then resolving any discrepancies. RESULTS Patients' positive attitudes toward insulin focus on its efficacy and efficiency, the avoidance of complications, and feeling better and more energetic. Negative attitudes were much more frequently discussed and include "technical concerns": anxiety about the pain, proper techniques, and general hassles of taking injections; about hypoglycemic symptoms; and about insulin causing serious health problems; and "experimental concerns": sensing that the disease has progressed into a serious phase, that past treatment efforts have failed, and that the patient has not taken proper care. Attitudes were based on personal experience, observation, what others say, and interactions with health care professionals. CONCLUSIONS Results from the few published reports on NIDDM patients' attitudes about insulin from various cultural settings were consistent with our findings, indicating that these themes may be generally applicable to a wider population. It is recommended that health care providers take care to avoid unwitting promotion of negative attitudes toward insulin and actively elicit and respond to patient attitudes to reduce reluctance to take the medication.

Abstract
BACKGROUND People with a family history of colorectal cancer have an increased risk of the disease themselves. Many centres are advocating family history screening by endoscopy. AIMS The performance of chemical and immunological faecal occult blood tests (Haemoccult and Hemeselect) in 212 subjects with a family history of colorectal cancer was assessed. RESULTS Both Hemeselect and Haemoccult were positive in the only patient with colorectal cancer. Hemeselect was more sensitive than Haemoccult for adenomas (40% compared with 20%) (adenomas larger than 1 cm 75% compared with 50%). No additional abnormality was detected by the addition of Haemoccult or Hemeselect to 60 cm flexible sigmoidoscopy in screening people at lower levels of familial risk. A false positive rate of 16% for Hemeselect resulted in a high proportion of additional colonoscopies in this group. CONCLUSIONS At present faecal occult blood tests are not sufficiently sensitive or specific to replace endoscopy in screening people at risk of familial colorectal cancer.

Abstract
Colonoscopy is the established method of surveillance of subjects at high risk of developing colorectal neoplasia but the procedure is expensive, time consuming and occasionally hazardous. Faecal occult blood tests can be prepared at home and are cheap, simple and safe. Hemeselect is an immunological faecal occult blood test that is more sensitive for colorectal cancer than Haemoccult. The aim of this study was to determine the sensitivity of the Hemeselect test for asymptomatic colorectal neoplasia in subjects at high risk of the disease who were undergoing colonoscopy, thus assessing its suitability as an alternative means of screening high-risk groups. A total of 919 asymptomatic subjects were asked to complete Hemeselect tests. These were completed satisfactorily by 808 individuals (compliance rate 88 per cent) and were positive in 164 patients (20 per cent). At colonoscopy 11 cancers were detected in ten patients (seven Hemeselect positive) and 36 (16 Hemeselect positive) had at least one adenoma 1 cm or more in diameter. The test sensitivites of Hemeselect for carcinoma and large (1 cm or more) adenomas were 70 and 44 per cent respectively. In a subset of 417 subjects who also completed Haemoccult tests, the sensitivities were 33 and 18 per cent. Hemeselect specificity is 88 per cent compared with 98 per cent for Haemoccult. While the sensitivity of Hemeselect is higher than that of Haemoccult, it is still insufficient to replace colonoscopy in high-risk groups.

Abstract
In a single-blind study 38 individuals at increased risk of developing colorectal cancer because of a family history of the disease were randomized to take 10.5 g wheat fibre (Trifyba) or 60 ml lactulose daily for 12 weeks. Rectal biopsies were taken before and after treatment and rectal mucosal proliferation was measured by the crypt cell production rate (CCPR). The mean(s.d.) CCPR was significantly lower in those taking wheat fibre after 12 weeks (7.2(3.4) crypt cells per crypt per h) compared both with values obtained before treatment with wheat fibre (10.2(5.1) crypt cells per crypt per h; P = 0.02) and after treatment with lactulose (9.4(3.8) crypt cells per crypt per h; P = 0.05). Proliferation in the lactulose group was not significantly different at 12 weeks compared with the value obtained before treatment. This study confirms an antiproliferative effect of wheat fibre in a group of high-risk individuals.
