Patient perception of quality of care provided by specialists and generalists.

Efforts to control medical care costs have focused on reducing the number of specialists directing patient care. This cross-sectional survey evaluated multiple sclerosis patient perceptions of the quality of care across three patterns of care: primary care (n = 156), single specialty care (n = 338), and comprehensive care (n = 75). The pattern of medical care received by the patient was defined by: (1) whether the MS provider was a primary care physician or (2) a neurologist; (3) whether the patient reported using other specialty services, such as psychological, rehabilitation, or social work services. Process indicators of quality of care were measured by subscales for interpersonal aspects of care, access to care, and perceived action plan. The MSQOL-54 was used to measure health-related quality of life. Pattern of care was not related to the Interpersonal or Access dimensions of care, after adjusting for health status and sociodemographic characteristics. Patients in the Single Specialty and Comprehensive Care patterns of care were, however, more likely to report their MS provider having and implementing an action plan. We conclude that MS patients who receive Single Specialty and Comprehensive Care are more likely to get diagnostic and treatment-related tests, as well as immunotherapeutic and experimental treatments.

Implications of recent hypertension trials for the generalist physician: whom do we treat, and how?

The publication of the results of the Swedish Trial in Old Patients with Hypertension-2 (STOP-2) and the termination of the doxazocin arm of the Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack (ALLHAT) study again raise the question of whether all antihypertensives deliver equal cardiovascular outcome benefits. Data from research on congestive heart failure and from the Heart Outcomes Prevention Evaluation (HOPE) trial illuminate the roles and possible mechanisms of humoral mediators of vascular damage, suggesting, first, that some antihypertensives (thiazides, beta-blockers, and angiotensin-converting enzyme inhibitors) can deliver more improvement in outcomes than other agents and, second, that decisions on whom to treat are best made based on risk appraisal, not merely pressures.

Locomotion of lizards on inclines and perches: hindlimb kinematics of an arboreal specialist and a terrestrial generalist.

Arboreal animals, especially lizards, often traverse three-dimensional networks of narrow perches with variable and steep inclines, but the effects of both incline and narrow surfaces on the locomotor movement and function of limbs are poorly understood. Thus, we quantified the three-dimensional hindlimb kinematics of a specialized arboreal lizard, Chamaeleo calyptratus, moving horizontally, and up and down a 30 degrees incline on a narrow (2.4 cm) perch and a flat surface. We compared the flat-surface data of C. calyptratus with those of an anatomically generalized terrestrial lizard, Dipsosaurus dorsalis. Inclines had significant main effects for relatively few kinematic variables of C. calyptratus (11%) compared to D. dorsalis (73%). For C. calyptratus, the main effects of locomotor surface were nearly three times more widespread than those of incline. The foot of C. calyptratus was markedly anterior to the hip at footfall, primarily as a result of an unusually extended knee for a lizard. A large amount of knee flexion during early stance may be used by C. calyptratus to actively pull the body forward in a manner not found in D. dorsalis. Unexpectedly, the pelvic rotation of C. calyptratus greatly exceeded that of D. dorsalis and, unlike D. dorsalis, was not affected by incline. The more medial location of the foot of C. calyptratus on the narrow perch during stance was primarily a result of knee flexion rather than femur depression. Unlike previous qualitative descriptions of chameleons, our data for the hindlimb posture of C. calyptratus during stance indicate that the limb was not particularly erect.

Modulation of attack behavior and its effect on feeding performance in a trophic generalist fish,

This study examines the ability of a temperate marine fish, Hexagrammos decagrammus, to modulate its prey capture behavior in response to differences in prey type. This species has an extremely broad diet, feeding on prey which demonstrate very different anti-capture behaviors. Video-taped attacks on three shrimp species, one crab and pieces of shrimp were analyzed to determine the relative contributions of suction-feeding and ram-feeding behaviors to prey capture. The prey capture behaviors used by the predator were related to differences in escape behavior among the three shrimp species. H. decagrammus used behaviors characteristic of other ram-feeding predators when feeding on the two most elusive shrimp species: high attack velocity, attack initiated at a greater distance from the prey, and greater movement of the predator relative to the prey. Strikes at crabs and pieces of shrimp elicited strikes more typical of other suction-feeding predators, with lower attack velocities, shorter initial predator­prey distances and greater relative movement of the prey towards the predator. Attacks on the least elusive shrimp species showed elements of both ram and suction feeding. Modulation of attack velocity increased capture success on elusive prey, supporting the hypothesis that diet diversity is associated with the presence of a repertoire of feeding behaviors. These data suggest that functional differences in prey anti-capture behavior, as well as the functional versatility of the predator, must be addressed in ecomorphological studies that try to correlate predator morphology with diet.

Post-ingestive feedbacks and associative learning regulate the intake of unsuitable sterols in a generalist grasshopper.

Behavioural studies of the grasshopper Schistocerca americana were undertaken to identify the mechanisms that regulate the intake of dietary sterols. In the first experiment, grasshoppers were allowed to feed on spinach, a plant containing only unsuitable sterols; immediately after this first meal, a suitable or unsuitable sterol was injected into the haemolymph. Grasshoppers injected with unsuitable sterols had second meals on spinach that were significantly shorter than those of grasshoppers injected with suitable sterols, indicating that unsuitable dietary sterols are detected post-ingestively. In the second experiment, grasshoppers were fed food containing only unsuitable sterols and were then presented with glass-fibre discs containing different concentrations of a suitable sterol or sucrose only (the control). The results suggest that grasshoppers do not use a direct feedback operating on mouthpart chemoreceptors to regulate their intake of suitable sterols. In the third experiment, grasshoppers were presented with artificial diets containing different sterols and flavours, and feeding was observed over a sequence of meals. The results from both the first and last experiments suggest a role for associative learning in regulating the intake of unsuitable sterols.

Transfer of knowledge from the specialist to the generalist by videoconferencing: effect on diabetes care.

We conducted a 12-month prospective interventional study of videoconferencing between primary and secondary care. A treatment network consisting of a diabetes specialist and four general practitioners was established. The communications medium was PC-based videoconferencing via ISDN at 128 kbit/s. A total of 154 type 2 diabetic patients entered the study. The specialist was contacted 94 times via videoconferencing. Metabolic and haemodynamic parameters were significantly improved over the course of the study: the mean HbA1c level fell from 8.1% to 7.8%, systolic blood pressure from 156 to 148 mmHg and diastolic blood pressure from 88 to 83 mmHg. The study demonstrated that therapeutic counselling by videoconferencing is feasible in diabetes care and suggests that it reduces hospital admissions and improves the quality of care.

Generalist and specialist nurses: caring for a patient with a stoma.

This article looks at the legal liability of a specialist nurse in relation to the general nurse who has invited her advice on the care of the patient. It considers the law relating to negligent advice and the concept of vicarious liability. It also looks at the dangers which could result from the specialist nurse taking over basic care of the patient as general nurses become deskilled.

Frail older patient care by interdisciplinary teams: a primer for generalists.

Frail older patients-unlike younger persons in the health care system or even well elders-require complex care. Most frail older patients have multiple chronic illnesses. Optimum care cannot be achieved by following the paradigm of ongoing traditional health care, which emphasizes disease and cure. Because no one health care professional can possibly have all of the specialized skills required to implement such a model of health care delivery, interdisciplinary team care has evolved. This paper describes the roles of the participating team members in the context of interdisciplinary care for frail older adults. In addition, the challenges that occur when Geriatric Interdisciplinary (ID) Teams involved in providing care to frail older patients are identified and discussed.
