Patient Attitudes Toward Physician's Assistants

A study was conducted in urban Los Angeles to assess patient acceptance of the use of physician''s assistants. Data collection was facilitated by the development of an attitude scale and responses were analyzed to determine differences between various socioeconomic stratifications. With a few exceptions, acceptance was highest among non-married middle-class respondents who have had some exposure to college. As to the perceived complexity of procedures a physician''s assistant might perform, 91 percent of all respondents would not object to injections administered by a physician''s assistant, but this tolerance diminishes to 34 percent in the case of first examination of a patient by a physician''s assistant if there appeared to be a serious head injury.     

Attachment of a physician's assistant to an English general practice.

A final-year student from the physician''s associate programme at Duke University in North Carolina, USA, worked in an English health centre for eight weeks between May and July. He managed 221 cases under supervision, and they were typical in terms of sex ratio, diagnosis, and the preponderance of children. Current social and economic trends in Britain suggest that selective under-doctoring, especially in inner urban areas, may become acute, and a type of physician''s assistant specially selected and trained for the work in areas with serious and unusual problems should be considered as among the possible, even desirable, solutions.     

Assistants to Primary Physicians in California

The mid-level practitioner movement is no longer experimental; nurse practitioners and physician''s assistants in California have proved to fill a necessary and viable professional role in the delivery of primary health care. The physician''s assistant law (AB2109) and the Experimental Manpower Act (AB1503) have facilitated the training and functioning of these new health care professionals; more comprehensive laws are still needed to permit optimal utilization. National agencies for approval of teaching programs and testing of individual graduates will play an increasing role in the accreditation and certification procedures. Professional role difficulties, issues of sex and questions of delegation of responsibility are being resolved and it is hoped that a more equitable and patient-oriented system is evolving.     

Electroacupuncture in fibromyalgia: results of a controlled trial.

OBJECTIVE--To determine the efficacy of electroacupuncture in patients with fibromyalgia, a syndrome of unknown origin causing diffuse musculoskeletal pain. DESIGN--Three weeks'' randomised study with blinded patients and evaluating physician. SETTING--University divisions of physical medicine and rehabilitation and rheumatology, Geneva. PATIENTS--70 patients (54 women) referred to the division for fibromyalgia as defined by the American College of Rheumatology. INTERVENTIONS--Patients were randomised to electroacupuncture (n = 36) or a sham procedure (n = 34) by means of an electronic numbers generator. MAIN OUTCOME MEASURES--Pain threshold, number of analgesic tablets used, regional pain score, pain recorded on visual analogue scale, sleep quality, morning stiffness, and patient''s and evaluating physician''s appreciation. RESULTS--Seven of the eight outcome parameters showed a significant improvement in the active treatment group whereas none were improved in the sham treatment group. Differences between the groups were significant for five of the eight outcome measures after treatment. CONCLUSIONS--Electroacupuncture is effective in relieving symptoms of fibromyalgia. Its potential in long term management should now be studied.     

Managing uncertainty in family practice.

Because patients present in the early stages of undifferentiated problems, the family physician often faces uncertainty, especially in diagnosis and management. The physician''s uncertainty may be unacceptable to the patient and may lead to inappropriate use of diagnostic procedures. The problem is intensified by the physician''s hospital training, which emphasizes mastery of available knowledge and decision-making based on certainty. Strategies by which a physician may manage uncertainty include (a) a more open doctor-patient relationship, (b) understanding the patient''s reason for attending the office, (c) a thorough assessment of the problem, (d) a commitment to reassessment and (e) appropriate consultation.     

Nurse Practitioner and Physician's Assistant Clinics in Rural California: Part I: Issues

The primary health care needs of at least 26 rural California communities are being served by nurse practitioners (NP''s) or physician''s assistants (PA''s). All of these have physician supervision and support. NP''s and PA''s have proved to be acceptable and effective. With 230 rural areas in California identified as having unmet health care needs, this type of service is likely to increase and should be supported.NP/PA clinics serve total populations or concentrate on Indians, Chicanos or the poor. Many barriers have been overcome, especially over the past four years, to allow these clinics to flourish and increase in number. The availability of nurse practitioners and physician''s assistants has increased due to support to schools and to school policies. Clinic funding has greatly improved; federal funds for general rural clinics, Indians, migrants, family planning and maternalchild health have been greatly supplemented by California state funds. Beginning in 1978, rural NP and PA services can be reimbursed by Medicare and Medi-Cal (California''s Medicaid program).Since 1975 state laws have defined PA and NP roles broadly, and these roles are more precisely defined at the local level. Although nurse practitioners and physician''s assistants generally cannot prescribe or dispense drugs (a major problem in many clinics), demonstration legislation allows special pilot projects to do both. As remaining funding and legal problems are corrected, NP''s and PA''s will serve an even greater role in rural areas.     

A practical classification of untoward drug effects.

All drug effects can be explained as results of complex interactions between the drug, the patient and his condition, and additional extrinsic factors. On the basis of these three "determinants", a practical classification of untoward drug effects (UDE) is suggested. UDE lists using this classification would fulfill the physician''s informational needs better than the material with which he is presently provided.     

Physician and patient predictors of evidence-based prescribing in heart failure: a multilevel study

Background

The management of patients with heart failure (HF) needs to account for changeable and complex individual clinical characteristics. The use of renin angiotensin system inhibitors (RAAS-I) to target doses is recommended by guidelines. But physicians seemingly do not sufficiently follow this recommendation, while little is known about the physician and patient predictors of adherence.

Methods

To examine the coherence of primary care (PC) physicians'' knowledge and self-perceived competencies regarding RAAS-I with their respective prescribing behavior being related to patient-associated barriers. Cross-sectional follow-up study after a randomized medical educational intervention trial with a seven month observation period. PC physicians (n = 37) and patients with systolic HF (n = 168) from practices in Baden-Wuerttemberg. Measurements were knowledge (blueprint-based multiple choice test), self-perceived competencies (questionnaire on global confidence in the therapy and on frequency of use of RAAS-I), and patient variables (age, gender, NYHA functional status, blood pressure, potassium level, renal function). Prescribing was collected from the trials'' documentation. The target variable consisted of ≥50% of recommended RAAS-I dosage being investigated by two-level logistic regression models.

Results

Patients (69% male, mean age 68.8 years) showed symptomatic and objectified left ventricular (NYHA II vs. III/IV: 51% vs. 49% and mean LVEF 33.3%) and renal (GFR<50%: 22%) impairment. Mean percentage of RAAS-I target dose was 47%, 59% of patients receiving ≥50%. Determinants of improved prescribing of RAAS-I were patient age (OR 0.95, CI 0.92–0.99, p = 0.01), physician''s global self-confidence at follow-up (OR 1.09, CI 1.02–1.05, p = 0.01) and NYHA class (II vs. III/IV) (OR 0.63, CI 0.38–1.05, p = 0.08).

Conclusions

A change in physician''s confidence as a predictor of RAAS-I dose increase is a new finding that might reflect an intervention effect of improved physicians'' intention and that might foster novel strategies to improve safe evidence-based prescribing. These should include targeting knowledge, attitudes and skills.     

A new plan quality index for nasopharyngeal cancer SIB IMRT

A new plan quality index integrating dosimetric and radiobiological indices was proposed to facilitate the evaluation and comparison of simultaneous integrated boost (SIB) intensity modulated radiotherapy (IMRT) plans for nasopharyngeal cancer (NPC) patients.Ten NPC patients treated by SIB-IMRT were enrolled in the study. Custom software was developed to read dose–volume histogram (DVH) curves from the treatment planning system (TPS). A plan filtering matrix was introduced to filter plans that fail to satisfy treatment protocol. Target plan quality indices and organ at risk (OAR) plan quality indices were calculated for qualified plans. A unique composite plan quality index (CPQI) was proposed based on the relative weight of these indices to evaluate and compare competing plans. Plan ranking results were compared with detailed statistical analysis, radiation oncology quality system (ROQS) scoring results and physician's evaluation results to verify the accuracy of this new plan quality index.The average CPQI values for plans with OAR priority of low, normal, high, and PTV only were 0.22 ± 0.08, 0.49 ± 0.077, 0.71 ± 0.062, and −0.21 ± 0.16, respectively. There were significant differences among these plan quality indices (One-way ANOVA test, p < 0.01). This was consistent with statistical analysis, ROQS results and physician's ranking results in which 90% OAR high plans were selected.Plan filtering matrix was able to speed up the plan evaluation process. The new matrix plan quality index CPQI showed good consistence with physician ranking results. It is a promising index for NPC SIB-IMRT plan evaluation.     

Focal hyperhidrosis: diagnosis and management

HYPERHIDROSIS, A CONDITION CHARACTERIZED by excessive sweating, can be generalized or focal. Generalized hyperhidrosis involves the entire body and is usually part of an underlying condition, most often an infectious, endocrine or neurologic disorder. Focal hyperhidrosis is idiopathic, occurring in otherwise healthy people. It affects 1 or more body areas, most often the palms, armpits, soles or face. Almost 3% of the general population, largely people aged between 25 and 64 years, experience hyperhidrosis. The condition carries a substantial psychological and social burden, since it interferes with daily activities. However, patients rarely seek a physician''s help because many are unaware that they have a treatable medical disorder. Early detection and management of hyperhidrosis can significantly improve a patient''s quality of life. There are various topical, systemic, surgical and nonsurgical treatments available with efficacy rates greater than 90%–95%.Hyperhidrosis, or increased production of sweat, can have a deeply detrimental effect on a patient''s quality of life, resulting in dramatic impairments of daily activities, social interactions and occupational activities.^1,2 It can be generalized, involving the whole body, or focal, involving a limited body area, most often the feet, armpits, hands or face. It is as common a disorder as psoriasis.³ However, patients rarely seek a physician''s help because many are unaware that they have a treatable medical disorder. In this article, we review the possible causes, pathophysiology, diagnosis and clinical manifestations of focal hyperhidrosis as well as the wide range of treatment modalities available today.     

Physician Presence in an Ambulance Car Is Associated with Increased Survival in Out-of-Hospital Cardiac Arrest: A Prospective Cohort Analysis

The presence of a physician seems to be beneficial for pre-hospital cardiopulmonary resuscitation (CPR) of patients with out-of-hospital cardiac arrest. However, the effectiveness of a physician''s presence during CPR before hospital arrival has not been established. We conducted a prospective, non-randomized, observational study using national data from out-of-hospital cardiac arrests between 2005 and 2010 in Japan. We performed a propensity analysis and examined the association between a physician''s presence during an ambulance car ride and short- and long-term survival from out-of-hospital cardiac arrest. Specifically, a full non-parsimonious logistic regression model was fitted with the physician presence in the ambulance as the dependent variable; the independent variables included all study variables except for endpoint variables plus dummy variables for the 47 prefectures in Japan (i.e., 46 variables). In total, 619,928 out-of-hospital cardiac arrest cases that met the inclusion criteria were analyzed. Among propensity-matched patients, a positive association was observed between a physician''s presence during an ambulance car ride and return of spontaneous circulation (ROSC) before hospital arrival, 1-month survival, and 1-month survival with minimal neurological or physical impairment (ROSC: OR = 1.84, 95% CI 1.63–2.07, p = 0.00 in adjusted for propensity and all covariates); 1-month survival: OR = 1.29, 95% CI 1.04–1.61, p = 0.02 in adjusted for propensity and all covariates); cerebral performance category (1 or 2): OR = 1.54, 95% CI 1.03–2.29, p = 0.04 in adjusted for propensity and all covariates); and overall performance category (1 or 2): OR = 1.50, 95% CI 1.01–2.24, p = 0.05 in adjusted for propensity and all covariates). A prospective observational study using national data from out-of-hospital cardiac arrests shows that a physician''s presence during an ambulance car ride was independently associated with increased short- and long-term survival.     

THE HIGH SCHOOL FOOTBALL TEAM PHYSICIAN

Mutual confidence is necessary between the football coach and the team physician. The physician''s decision in the matter of a boy''s condition must always be final. The coach should also consider the physician''s advice in shaping his psychological appeals to the players in before-game and between-halves talks. The physician should be on his way to a man injured on the field as soon as the play is ended. It is up to him and not the trainer or coach to make the diagnosis. The physician must have the ability to make an immediate evaluation of the extent of injury and use appropriate measures to get the player off the field. To see a semi-conscious man with dangling head being half dragged off the field is far worse from the patient''s standpoint and from the spectator''s standpoint than removal by stretcher.     

Doctor-patient communications revisited

To test a new approach to detecting and managing hypertension, 34 family practices in southwestern Ontario that comprised 32 124 patients aged 20 to 65 years were randomly assigned in a 5-year study to either undertake a system of care in which a medical assistant oversaw screening and attended to education, compliance and follow-up (experimental group) or continue their usual practices (control group). The 17 physicians in the experimental practices (15 659 patients) were matched with the 17 in the control practices (16 465 patients) according to size of the community, sex, level of practice activity and length of time in practice. Hypertension was defined as at least two diastolic blood pressure readings over 90 mm Hg. More patients in the experimental group than in the control group were screened at least once (91% v. 80%); the former were more likely to have lower systolic blood pressure (p less than 0.02), to be compliant (p less than 0.05) and to be very satisfied with care (p less than 0.01). There were no significant differences between the two groups in the rates of illness and death due to cardiovascular disease for all patients or for hypertensive patients. The unassisted family physician can provide effective care for hypertensive patients. However, minor modifications in the physician''s practices can improve care.     

Physician self-awareness: the neglected insight.

Self-awareness is vital to a physician''s development. Understanding the impact of our internal subjective world on our attitudes and values and on the fantasies we have of reality is important to us as doctors. Some of the means of acquiring this self-knowledge include accurately perceiving the reflection of one''s self in patients, understanding one''s learning style, studying and enjoying the humanities, expressing one''s self creatively, maintaining a sense of humour and examining one''s reaction to experiences. When confronted by a person who is ill the physician must take action that is constructive and affirmative and not compromised by behaviour that originates in unexamined personal issues.     

Audit of admission to medical school: II--Shortlisting and interviews.

Analysis of shortlisting of applicants for interview at St Mary''s Hospital Medical School showed that factor analysis could reduce the selection criteria to three independent scales--"academic ability," "interests," and "community service"--all of which contributed to the interview decision. Early applicants scored more highly on all three factors but were still at a greater advantage in selection for interview than would have been predicted. The dean''s judgment of priority for interview from the UCCA form was found to predict a candidate''s chance of acceptance at other medical schools besides St Mary''s. Analysis of interviewing showed high correlations among interviewers in their assessments, although there was evidence of influence by the chairmen. Factor analysis showed three major factors--academic suitability, non-academic suitability, and health--of which non academic suitability was the major determinant of interview success. Non academic suitability was related to personality (high extraversion and low psychoticism) and to the choices made on the UCCA form. The system of admission interviews enabled greater emphasis to be put on broader interests and achievements than if selection had been on the basis of UCCA application form alone.     

Do physicians have an ethical obligation to care for patients with AIDS?

This paper responds to the question: Do physicians have an ethical obligation to care for patients with acquired immunodeficiency syndrome (AIDS)? First, the social and political milieu in which this question arises is sampled. Here physicians as well as other members of the community are found declaring an unwillingness to be exposed to people with AIDS. Next, laws, regulations, ethical codes and principles, and the history of the practice of medicine are examined, and the literature as it pertains to these areas is reviewed. The obligation to care for patients with AIDS, however, cannot be located in an orientation to morality defined in rules and codes and an appeal to legalistic fairness. By turning to the orientation to morality that emerges naturally from connection and is defined in caring, the physicians'' ethical obligation to care for patients with AIDS is found. Through an exploration of the writings of modern medical ethicists, it is clear that the purpose of the practice of medicine is healing, which can only be accomplished in relationship to the patient. It is in relationship to patients that the physician has the opportunity for self-realization. In fact, the physician is physician in relationship to patients and only to the extent that he or she acts virtuously by being morally responsible for and to those patients. Not to do so diminishes the physician''s ethical ideal, a vision of the physician as good physician, which has consequences for the physician''s capacity to care and for the practice of medicine.     

A Clinico-Mycological Study of Dermatophytoses in Goa,India

The study was a clinico-mycological approach to find out the various clinical types of dermatophytoses and as well as the species of dermatophytes in Goa. Various socio-demographic and host factors were assessed to determine the predisposing factors for dermatophytoses. A detailed clinical history of the patients was recorded. Samples were collected aseptically in sterile black paper envelopes. The material was subjected to microscopy using potassium hydroxide mount. Culture was done by inoculating the material in Sabouraud’s peptone glucose agar slants. Tinea corporis was found to be the most common clinical presentation (44.2 %). Among the dermatophytes, Trichophyton rubrum predominated (38.2 %), followed by Trichophyton mentagrophytes (27.2 %). Dermatophytoses was more common among the lower and upper lower strata of society. Majority of the patients were in the 21–40 years age group (62 %) with males predominating women in ratio 2.4:1.     

Doctors and patients don't agree: cross sectional study of patients' and doctors' perceptions and assessments of disability in multiple sclerosis.

OBJECTIVES: To compare the judgments of clinicians on which domains of health in the short form questionnaire (SF-36) would be most important to patients with multiple sclerosis with the opinions of patients themselves; to compare assessment of physical disability in multiple sclerosis by a clinician using Kurtzke''s expanded disability status scale and a non-clinically qualified assistant using the Office of Population Census and Surveys'' (OPCS) disability scale with self assessment of disability and other domains of health related quality of life by patients using the SF-36 and the EuroQol questionnaire; and to compare the scores of patients for each domain of the SF-36 with control data matched for age and sex. DESIGN: Cross sectional study. SETTING: Clinical department of neurology, Edinburgh. SUBJECTS: 42 consecutive patients with multiple sclerosis attending a neurology outpatient clinic for review or a neurology ward for rehabilitation. MAIN OUTCOME MEASURES: Scores on the SF-36; EuroQol; Kurtzke''s expanded disability status scale; the OPCS disability scale. RESULTS: Patients and clinicians disagreed on which domains of health status were most important (chi 2 = 21, df = 7, P = 0.003). Patients'' assessment of their physical disability using the physical functioning domain of the SF-36 was highly correlated with the clinicians'' assessment (r = -0.87, P < 0.001) and the non-clinical assessment (r = -0.90, P < 0.001). However, none of the measures of physical disability correlated with overall health related quality of life measured with EuroQol, Quality of life correlated with vitality, general health, and mental health in the SF-36, each of which patients rated as more important than clinicians and for each of which patients scored lower than the controls. CONCLUSIONS: Patients with multiple sclerosis and possibly those with other chronic diseases are less concerned than their clinicians about physical disability in their illness. Clinical trials in multiple sclerosis should assess the effect of treatment on the other elements of health status that patients consider important, which are also affected by the disease process, are more closely related to overall health related quality of life, and may well be adversely affected by side effects of treatment.     

Bioethics for clinicians: 12. Ethical dilemmas that arise in the care of pregnant women: rethinking "maternal-fetal conflicts".

When a pregnant woman makes a decision or acts in a manner that may be detrimental to the health and well-being of her fetus, her physician may be faced with an ethical dilemma. Is the physician''s primary duty to respect the woman''s autonomy, or to promote behaviour that may be in the best interest of the fetus? The controversial concept of "fetal rights" or the "fetus as a patient" contributes to the notion that the pregnant woman and her fetus are potential adversaries. However, Canadian law has upheld women''s right to life, liberty and security of the person and has not recognized fetal rights. If a woman is competent and refuses medical advice, her decision must be respected even if the physician believes that her fetus will suffer as a result. Coercion of the woman is not permissible no matter what appears to be in the best interest of the fetus.
