Clinical and cost effectiveness of the counter-rotational brush in private practice.

There have previously been no studies on the cost effectiveness of the use of a counter-rotational toothbrush (INTERPLAK Home Plaque-Removal Instrument), which has been demonstrated to be more effective than ordinary toothbrushes in reaching plaque-removal and gingival-health goals. Killoy et al studied the costs of required periodontal treatment for 32 patients with moderate periodontitis at two corporate capitation dental centers. The subjects were divided into two groups, a test group that brushed with a counter-rotational toothbrush and one that brushed with a manual toothbrush. Probing depth, attachment levels, and plaque and bleeding indexes in the test brush group were better than those in the control group. The end result was a mean reduction of $535 in the cost of periodontal treatment that had been planned before using the counter-rotational brush over 18 months, while the group using the manual brush experienced a mean increase of $11 in required treatment over original plans. Furthermore, the test group reached a state of gingival health, but the control group did not. The study concluded that the counter-rotational brush is cost effective.

Ten-year follow-up survey of clinical neuropsychologists: part I. Practices and beliefs.

A 21-item questionnaire previously used to survey practices and beliefs of clinical neuropsychologists (Sweet & Moberg, 1990; Sweet, Moberg, & Westergaard, 1996) was mailed in February 1999 to all ABPP Diplomates in clinical neuropsychology and a larger sample of randomly selected non-ABPP members of Division 40 (Clinical Neuropsychology) of the American Psychological Association. Results were compared with data previously collected in 1989 and 1994. Across 10 years there have been some persistent differences between neuropsychologists based on board certification status. These differences include degree of involvement in neuropsychological practice and forensic practice, involvement in research and teaching, frequency of subscribing to or regularly reading a variety of relevant journals, employment settings, use of assistants, and use of projective assessment. There are also a number of areas of shared belief and common practice. These important areas of agreement are unrelated to board certification status and are interpreted as signs of cohesiveness and maturity in the continuing evolution of the subspecialty. Shared beliefs and common practices include: appropriate field of training, type of degree, assessment philosophy, most types of information to be gathered in evaluations, and time spent per assessment. In general, the use of assistants is correlated significantly with the number of evaluations performed per month. Although sometimes viewed as exclusively providing assessment, the majority of neuropsychologists are also involved in treating patients with brain dysfunction. Survey data appear useful in characterizing and monitoring professional status and trends of clinical neuropsychology.

Effect of medicolegal liability on patterns of general and family practice in Canada.

As part of the Federal/Provincial/Territorial Review on Liability and Compensation Issues in Health Care, in 1988 we surveyed Canadian general practitioners and family physicians to determine the effect of liability concerns on their practices in the previous 5 years. Questionnaires were sent to a random, stratified national sample of 1295 physicians, with a response rate of 64.6%. However, a high proportion of the returned questionnaires were ineligible because the physicians were not in general or family practice, were not involved in direct patient care, or had died or moved; thus, the corrected response rate was 50.8%. The newsletter of the Canadian Medical Protective Association was the source of information on liability most frequently cited (by 88.1% of the physicians) and most influential (to 62.4%). Only 15.5% of the physicians cited personal involvement with medicolegal issues as a source of information; the rate was higher for Ontario physicians and those in urban areas generally. A total of 74.6% of the respondents had altered their style of practice in the previous 5 years, and 56.3% reported changes in the scope of their practice. Concern about litigation was the most important reason for changing style of practice and reducing or eliminating administration of anesthesia, whereas lifestyle and other issues along with liability concerns most influenced decisions to reduce obstetric care and emergency department work. Our findings suggest that physicians' perceptions of liability issues have had a profound influence on primary care practice in Canada in the past several years.

Pediatric cardiology in the 1990s.

OBJECTIVES: In 1991, all active board-certified pediatric cardiologists were polled by questionnaire to examine the relation of subspecialty training and motivational and satisfaction issues to practice characteristics. BACKGROUND: Previous questionnaires with regard to manpower status and practice characteristics were published in 1967 and 1980. These indicated a field predominantly centered in academic medicine with growth in manpower close to predicted need. METHODS: The questionnaire was mailed to 844 of 884 active board-certified pediatric cardiologists and was returned anonymously by 570, a 68% response rate. RESULTS: Among respondents, the mean year in which fellowship training was completed was 1974. The average length of subspecialty training was 31 months for all respondents and 34 months among those completing training since 1981. Seventy-seven percent of subspecialty training centered on clinical training. Although there has been a slight increase in research training in recent years, only 18 respondents completed > or = 22 months of research training. Respondents devote a mean of 89% of professional hours to subspecialty activities and spend 63% of total hours in clinical care. Total hours, income and procedures were related to site of professional activity. Professional satisfaction was high in the factors considered more important: professional challenge and interaction, clinical resources, career security and clinical autonomy. CONCLUSIONS: The field of pediatric cardiology is a subspecialty centered on patient care and performance of diagnostic and interventional techniques. Professional activities varied according to practice site. Pediatric cardiologists with basic research training and professional activity remain a minority. Satisfaction is high, with greatest satisfaction in professional interactions and least satisfaction with income and free time.

Counselling: filling a gap in general practice.

A counsellor worked for 1 year in three practices in a rural area where there was previously no practice-based counselling. The service was evaluated, using a range of methods, in order to inform general practitioners and policy-makers about the demand for counselling, where it fits with other services, its potential value and how to organise and audit the service efficiently. Five kinds of information were collected: administrative data; patients' views; well-being scores; GPs' perceptions of individual patients; and interviews with the counsellor, GPs and other primary care staff by an independent researcher. All the GPs used the service, referring 131 people. The most common reason for referral was 'relationship difficulties'. There were improvements in patients' well-being, self-awareness and coping skills, and high satisfaction among GPs and patients. Communication with other services was seen to improve. The counselling service was found to fill a gap by addressing the needs of a substantial group of patients for whom psychiatric care was inappropriate.

Autoclave performance and operator knowledge of autoclave use in primary care: a survey of UK practices.

Changes in the delivery of health care have increased the demand for minor surgical and screening procedures in general practice. This has increased the risk of cross-infection with blood-borne viruses and the demand for sterile instruments. The aim of this study was to investigate the knowledge and training of medical personnel in England and Wales on aspects of autoclave use, and to test the effectiveness of their practice autoclaves. An anonymous postal questionnaire and autoclave performance survey using biological indicators was made of 700 general medical practitioners selected at random from FHSA lists from 12 Health Authorities in England and Wales. The overall response rate was 53.1% (N= 372) comprising 10% general practitioners and 90% practice nurses. Eighty-two percent of respondents used autoclaves with a mean age of 2.5 years, of which 91% had been serviced in the past year. While 35% of respondents made daily observation of gauges, 19% did not routinely monitor autoclave effectiveness. Six autoclaves failed to sterilize the spore test ampoules. Fourteen percent of respondents did not autoclave instruments after every patient. Only 33.1% reported wearing gloves during minor operations. Fifty five percent had training in cross-infection prevention. It was concluded that although there has been improvement in instrument decontamination procedures in general practice compared with previous surveys, further education of medical practitioners and practice nurses in the use of autoclaves and infection prevention and control is indicated. The failure of 2% of the autoclaves to kill spores suggests the need for increased monitoring of autoclave performance. Two-thirds of practitioners exposed themselves to increased risk of infection by carrying out minor surgery without the protection of gloves.

Activity analysis and cost study of clinical pharmacists practicing in a university medical center: comparison with previously established criteria.

The activities of three staff clinical pharmacists practicing in a university medical center hospital were studied using work sampling direct observation techniques. The results of the activity analysis were compared with the functional criteria of the Task Force on the Pharmacist's Clinical Role. It was found that the clinical pharmcists devoted a large portion (72.36 percent) of their total practice time to accomplishing professional activities. A very low percentage (2.27) of time was observed to be spent in nonproductive idle time. The cost to provide clinical pharmacy services to the 165.23 average census of inpatients supported by the clinical pharmacists was calculated to be $1.18 per patient per day. It was concluded that the observed pharmacists were highly motivated and provided a wide variety and extensive amount of professional clinical pharmacy services. Recommendations were made calling for research of other clinical pharmacy practice models, standardization of pharmacy activity terminology, determination of clinical pharmacy outcomes and identification of motivational factors present in the study model environment.

"Elder" physician assistants and their practices.

UNLABELLED: Physician assistants (PAs) in American medicine are aging. After 30 years of having PAs enter the US health care system, it seems an appropriate time to examine where they are in their careers. This study describes the phenomenon of a rising number of elder PAs in the ranks of the nation's health providers and their patterns of practice. METHOD: A subpopulation cohort of practicing PAs 60 years and older was compared to all PAs. Age range, gender, practice setting, specialty, and other demographic variables were analyzed using established methods. Differences between elder PAs and all other PAs and services provided by the two groups were examined. RESULTS: Elder PAs constituted about 1.6% of full-time PAs in practice in 1998. Average age of elder PAs is 64 years (range, 60 years to 74 years) compared to 41 years (range, 21 years to 60 years) for all full-time practicing PAs. Analysis of several variables--gender, ethnicity, geographic distribution, number of patients seen in a week, and hours worked in a week--revealed few differences between the cohorts. On average, older PAs were in practice longer than all PAs (18.3 years and 9.2 years, respectively), had been with their current employer for 7.7 years, and worked one job. Elder PAs had an associate degree at twice the rate of all PAs, but three times as many of them had a doctorate. Elder PAs are more likely to be taking care of older patients, working in a rural area, and remaining in a rural area longer than PAs overall. INTERPRETATION: America's corps of PAs continues to work into and beyond the usual retirement age for most workers, and is caring for a greater percentage of older persons than all PAs are. Most elder PAs practice in family or general medicine and prefer to practice in a rural area. These practice preferences mirror results of previous studies of the practices of elder physicians in the United States and Canada. The aging of PAs has important implications for clinical practice and health workforce planning. If PAs were encouraged to take early retirement, more elderly patients would be shifted to younger providers--with the potential to affect delivery of primary care services in rural communities.

Alternative birth practices and settings--indications of prevalence and use among California obstetricians.

Interest among women and families in "alternative" birth practices and settings has grown steadily in recent years, but little information has been available about the response of the medical profession to the desire for a more "natural," self-directed and family-centered childbirth experience. Data from a recent survey of California obstetricians, however, indicate that although home birth and delivery in freestanding alternative birth centers are discouraged or not permitted by most respondents, a large majority encourage and/or permit routinely or on request a wide variety of practices that represent departures from previous norms of clinical practice. Results of this study suggest that as long as the safety of the mother and infant are not jeopardized and unacceptable liability risks are not posed, physicians are increasingly willing to accommodate the preferences of patients and families for a more "high-touch" approach to counterbalance the increasing utilization of high technology in obstetrics.

Practice variation and physician-specific effects.

This study provides estimates of practice variation for primary physician services in Norway. Nearly all previous studies on practice variation have encompassed mainly specialist and hospital services. Thus we provide evidence for treatment variation for a health care sector where information about treatment variation is relatively scarce. Our analyses were carried out on a large set of data from individual physician practices. We estimated the extent of practice variation according to type of diagnosis and type of treatment option. The main finding is that variation in clinical practice between physicians is an important determinant of expenditure for primary physician services. Depending on the type of diagnosis, physician-specific effects explained 47-66% of the variation in expenditure for laboratory tests, 59-66% of the variation in expenditure for consultations lasting over 20min and 49-61% of the variation in expenditure for specific procedures. The age and gender of the patients explained only about 1% of the variation in expenditure. This finding supports the results from previous studies, which have shown that patients' age and gender are inadequate when used as risk adjusters. We also identified physicians who moved their practice from one municipality to another, i.e. they changed their patient population completely. Our results showed that those physicians who moved did not change practice style after they moved, i.e. that physician's style of practice is stabile. This indicates that practice style reflects a deeply rooted behaviour with respect to how to practice medicine.

Managing ADHD in general practice. N of 1 trials can help!

OBJECTIVE: To pilot single patient trials designed to improve decision making about stimulant use for attention deficit hyperactivity disorder (ADHD) in general practice. METHOD: Patients previously stabilised on dexamphetamine were enrolled from a general practice. Each undertook a six week same patient randomised, double blind, placebo controlled crossover comparison of dexamphetamine with placebo for ADHD. Rating scales were completed weekly by self, parent and teacher. RESULTS: Three of the four patients were clear responders to dexamphetamine (including a noncompleter, as his results still demonstrated a clear response). The results were clinically useful in each case. Management was confirmed for three patients and changed for one (who ceased dexamphetamine). DISCUSSION: Prescribing stimulant medications only to children with diagnosed ADHD and who are found to respond, limits use of these worrisome drugs to those who will respond, and minimises their use in those who will not benefit.

The role of screening for Helicobacter pylori in patients with duodenal ulceration in the primary health care setting.

BACKGROUND: It is known that at least 90% of duodenal ulcers are caused by infection with the bacterium Helicobacter pylori. Eradicating this organism usually results in complete resolution of the disease. Testing for H pylori was introduced relatively recently, and thus, many patients known to have uncomplicated peptic ulcer disease who continue to need long-term treatment with ulcer-healing drugs have never been tested for the infection or offered eradication therapy. In modern computerized practices, this subgroup of patients can readily be identified by reference to morbidity and repeat prescribing data. Eradication of H pylori infection in this group of patients has great potential benefit for the individuals concerned as well as cost-saving benefit for the National Health Service. AIM: The aim of this prospective study was to determine whether it is worthwhile screening for and treating H pylori infection in patients in a general practice population with previously diagnosed duodenal ulcer disease taking ulcer-healing drugs long term. METHOD: In 1994, in a practice of 7100 patients, morbidity and repeat prescribing data were used to identify 40 patients (0.6%) with proven duodenal ulcer disease taking ulcer-healing medication long term and with uncertain H pylori status. Twenty-nine of the 40 subjects agreed to undergo serology testing for H pylori antibodies. Of 20 (69%) who were positive, 18 (eight women, median age 63.8 years) were given eradication therapy. Seventeen patients received omeprazole 40 mg once daily and amoxycillin 500 mg three times daily for 14 days with metronidazole 400 mg three times daily for the first 7 days; for the remaining patient metronidazole was inadvertently omitted. [13C]Urea breath testing was carried out at the local hospital at least one month after therapy to determine whether eradication treatment had been successful. Subjects were also personally followed up by telephone after 1 and 4 months to assess the success of treatment subjectively. RESULTS: [13C]Urea breath testing showed that H pylori eradication was successful in all 17 patients (100%) who received the intended eradication regimen. Helicobacter pylori was not eradicated in the patient who received only omeprazole and amoxycillin. Four months after successful H pylori eradication, 13 of the 17 (76%) patients remained completely asymptomatic. Two of the four patients who had some recurrent dyspepsia had known gastro-oesophageal reflux and their ongoing symptoms after eradication therapy seemed, on close questioning, to be more attributable to this than to duodenal ulcer disease. CONCLUSION: Testing for and eradication of H pylori is worthwhile in general practice in those patients with previous proven duodenal ulceration who need long-term ulcer-healing medication. The high rate of eradication of H pylori achieved with the regimen used in this study compares very favourably with that of other treatment regimens. However, in patients with duodenal ulcers there may be coexisting pathology, and H pylori eradication does not necessarily result in complete disappearance of dyspeptic symptoms. Thus, when monitoring the outcome of treatment it is important to assess improvement of symptoms as well as objective evidence of eradication.

Early childhood caries and infant feeding practice.

OBJECTIVES: Early childhood caries (ECC) has been suggested as a new term to describe the presence of caries on at least one primary tooth in children under six years of age. The prevalence and severity of ECC in low socio-economic, immigrant and indigenous communities is high. The purpose of this study was to investigate the association between selected social and behavioural variables, including previous infant feeding practice, and the presence of ECC in an Australian child population. METHOD: A cross sectional sample of 3,375 four to six-year-old children from the north Brisbane region were examined in a school based setting using dmft/s indices and a self-administered questionnaire obtained information regarding social background and past infant feeding practice. The data were modelled using a forward stepwise logistic regression procedure to explore a statistical model for ECC presence. RESULTS: Significant determinants for ECC presence were ethnicity other than Caucasian (OR=1.99, CI=1.37, 2.88), language other than English (OR=1.97, CI=1.35, 2.86), single parent status (OR=1.93, CI=1.47, 2.52), sweetened bottle contents (OR=4.29, CI=2.90, 6.38), going to sleep with the bottle (OR=1.73, CI=1.49, 2.00) and sipping from the bottle during the day (OR=1.58, CI=1.35, 1.84). CONCLUSIONS: A statistical model for ECC presence and previous infant feeding practice has been constructed. This study supports the adoption of the proposed case definition of ECC.

How to divest acquired physician practices.

When an integrated delivery system (IDS) determines it must divest itself of a previously acquired physician practice, it must manage the transaction with care. The IDS most likely will want to maintain a positive ongoing relationship with the physician practice, while avoiding concessions to the practice that could be construed as violations of state and Federal laws. Before proceeding, the IDS should evaluate the reasons for divesting the practice, assess legal issues involved in terminating contracts with the practice, decide how to deal with the practice's assets and office facilities, consider whether covenants not to compete should be enforced, ensure continued access to essential medical records, consider whether to incorporate a "non-disparagement" clause in the termination agreement, and determine what mutual general releases may be necessary.

The effect of instructions on age differences in practical problem solving.

In previous research middle-aged adults have typically been found to perform better on practical, everyday problems than either younger or older adults. However, it has been suggested that young adults may not expend as much effort as middle-aged adults and therefore may not perform as well as they are capable of performing. In order to test this hypothesis, the performance of young, middle-aged, and elderly adults was compared on 10 practical, everyday problems. Half of the subjects were given standard instructions and half were given instructions that encouraged them to perform as well as they possibly could. With the standard instructions, the young adults performed less well than either the middle-aged or the elderly adults. With the more explicit instructions, however, the young adults performed as well as the middle-aged adults and better than the elderly adults. The results of this study indicate that there may be a tendency on the part of young adults to give less than their optimal performance unless explicitly instructed to do their best.

Impact of improved treatments on perceptions about HIV and safer sex among inner-city HIV-infected men and women.

Protease inhibitor combination therapies have significantly improved the health of many people with HIV/AIDS. Prior studies, consisting mainly of gay men, have indicated that these treatments have prompted reduced concern about HIV and an increase in high-risk behavior. This study assessed the impact of HIV treatment advances on HIV-infected individuals living in inner-city areas. A convenience sample was used (n = 196), consisting largely of heterosexual African-Americans and Hispanics. Almost the entire sample had heard of the latest HIV treatments, and 75% were currently on protease inhibitor regimens. One-third of the sample reported that AIDS was a less serious threat nowadays and that being HIV-positive was not a big deal. Fifteen percent of respondents believed that protease inhibitor combination therapies reduced the risk of HIV transmission, and 10% believed that these treatments reduced need for safer sex practices. As in previous studies of other populations, a significant percentage (23%) of respondents practiced safer sex less often since new HIV treatments arrived. HIV prevention programs need to focus more attention on HIV-infected individuals in inner city areas. Interventions for these individuals need to address changing attitudes and behaviors stemming from HIV treatment advances.

A comparative study of homeless, previously homeless, and never homeless school-aged children's health.

The purpose of this cross-sectional study was to compare the mental health, physical health, and healthcare practices of homeless, previously homeless, and never homeless poor school-aged children. The sample was comprised of 134 children who ranged in age from 8 to 12 years. The children participated in health assessments and completed two psychometric tests: the Children's Depression Inventory (CDI) (Kovacs, 1985) and the Revised Children's Manifest Anxiety Scale (RCMAS) (Reynolds & Richmond, 1985). Their mothers completed the Child Behavior Problem Checklist (CBCL) (Achenbach, 1991) and participated in an interview. The homeless (n = 67), previously homeless (n = 30), and never homeless children (n = 37) were similar in regard to their health assessment findings, reported health problems, healthcare practices, and CBCL scores. The proportions of homeless and previously homeless children with CDI scores in the clinical range were significantly greater than the never homeless poor children. The homeless children had significantly higher anxiety scores than the previously homeless and never homeless children. All three groups of children were at risk for physical and mental health problems; however, the findings suggest that school-aged children who experience homelessness may be at greater risk for depression and anxiety than never homeless poor children.
