Contemporary dental practice in the UK: demographic data and practising arrangements.

OBJECTIVES: To investigate, by questionnaire, various aspects of primary dental care provision in the North West of England and Scotland. METHOD: A questionnaire containing 79 questions was sent to 1,000 practitioners, selected at random, in the North West of England and Scotland. Non-responders were sent another questionnaire after a period of 4 weeks had elapsed. RESULTS: Overall a response rate of 70% was achieved. The majority of practitioners were practice principals (65%), working in a group NHS practice (80%) located in a city or town centre (49%). On average 10-20 patients were treated each session with fewer patients treated per session under private arrangements. Many practitioners were found to lack hygienist support (44%) and to employ unqualified dental nurses (82%). Younger practitioners were more likely than senior colleagues to have access to up-to-date computers whilst 37% and 74% of respondents never used CAL programmes or magnification respectively. Contemporary cross-infection control standards were used by the majority of practitioners, although 3% of practitioners reported only autoclaving their handpiece once a day. CONCLUSIONS: The majority of practitioners, involved in this study, worked under National Health Service (NHS) regulations as principals in a group practice where the workload was greater than the private/independent sector. Contemporary cross-infection procedures were used routinely. In contrast computer-aided learning programmes and magnification were not used routinely. The practitioners in this study employed significant numbers of unqualified dental nurses.

Infection control: public health, clinical effectiveness and education.

In this article the author discusses three main issues in infection control: the development of clinical effectiveness, education and public health. Present day infection control practice is based on principles put forward by Florence Nightingale over 100 years ago. Despite medical advances, hospital-acquired infection remains a major cause of morbidity and mortality. Further research is required to assess how effective present day infection control activities and policies are in reducing the spread of infection. The success of implementing evidence-based practice relies on multidisciplinary, user-friendly educational initiatives. It is imperative that community practitioners are involved in the promotion of infection control. Greater public awareness of infectious agents and the importance of basic hygiene will ensure that infection control cannot remain the exclusive property of hospitals, but must extend to all areas of public health.

Concerns regarding infection control recommendations for dental practice.

It goes without saying that the members of any professional group are more likely to modify their behavior if they are provided with logical, rational reasons to enact the suggested change. In the mid 1980s, health care providers, including dental personnel, were advised to adopt universal precautions and to alter their infection control habits with minimal justification, apart from the general unease and paranoia surrounding AIDS. Therefore, it is understandable that some practitioners would react with scepticism to the idea that their traditional infection control techniques were less than adequate, while others would overwhelmingly embrace the new recommendations in the misguided belief that personal, patient, staff and family safety would be enhanced. This predictable confusion is epitomized by the dentist who "sterilizes" extraction forceps by immersing them in alcohol for 10 minutes, versus the dentist who wears gloves, mask and disposable gown to conduct a recall examination. And if dentists are perplexed, it is clear that their staffs are equally, if not more confused, since they are exposed to the exaggerated claims and counter claims of sales agents. The microbes encountered in dental practise, apart from the hepatitis B virus, pose no significant risk to dental personnel or their patients, and the danger of hepatitis B transmission is reduced most effectively by vaccination. In reality, the genesis of dentistry's current emphasis on infection control resides entirely with HIV disease. But there is no credible clinical evidence to suggest that HIV infection is transmitted via dental treatment. Indeed, it may be theorized that for such a transmission to occur, the blood stream of the susceptible recipient would have to be invaded directly by a pathogenic inoculum of the virus--an unlikely event in the normal practise of dentistry. Under such circumstances, infection control practises should ignore the danger of HIV transmission, but concentrate on: Sterilization of all surgical and invasive instruments to protect patients from potential cross-infection. All dental staff receiving hepatitis B vaccinations. Dental staff wearing gloves, especially while performing intraoral procedures with blood release, and handling used instruments, to protect them from direct contact with potential pathogens. Working in a clean environment, in which blood spills and splatters are removed mainly for esthetic reasons. Such measures reflect the actual potential for disease transmission, as it exists in dentistry. They are justified and economical, and will be implemented by concerned but knowledgeable dental staff.

Trends in glove use by dentists in England and Wales: 1989-1992.

The routine wearing of gloves during the dental treatment of patients forms an integral part of the recommended guidelines of many authorities worldwide. Compliance has been variable but there is evidence to show that this is increasing, as are other cross-infection control measures. A survey of glove use by general dental practitioners in England and Wales was carried out in 1989. This paper reports a follow up study in 1991/2 which aimed to identify any differences that had occurred in the interim. The results indicated that there was increasing compliance with recommended cross-infection control measures, although only one fifth of respondents were found to change gloves between patients. Of those practitioners who did not change gloves between patients, half considered that blood contact was not a reason for changing gloves. Comparisons are made with compliance rates in other countries and recommendations made for further education within the dental profession on the subject of cross-infection control.

Artificial intelligence techniques for monitoring dangerous infections.

The monitoring and detection of nosocomial infections is a very important problem arising in hospitals. A hospital-acquired or nosocomial infection is a disease that develops after admission into the hospital and it is the consequence of a treatment, not necessarily a surgical one, performed by the medical staff. Nosocomial infections are dangerous because they are caused by bacteria which have dangerous (critical) resistance to antibiotics. This problem is very serious all over the world. In Italy, almost 5-8% of the patients admitted into hospitals develop this kind of infection. In order to reduce this figure, policies for controlling infections should be adopted by medical practitioners. In order to support them in this complex task, we have developed a system, called MERCURIO, capable of managing different aspects of the problem. The objectives of this system are the validation of microbiological data and the creation of a real time epidemiological information system. The system is useful for laboratory physicians, because it supports them in the execution of the microbiological analyses; for clinicians, because it supports them in the definition of the prophylaxis, of the most suitable antibi-otic therapy and in monitoring patients' infections; and for epidemiologists, because it allows them to identify outbreaks and to study infection dynamics. In order to achieve these objectives, we have adopted expert system and data mining techniques. We have also integrated a statistical module that monitors the diffusion of nosocomial infections over time in the hospital, and that strictly interacts with the knowledge based module. Data mining techniques have been used for improving the system knowledge base. The knowledge discovery process is not antithetic, but complementary to the one based on manual knowledge elicitation. In order to verify the reliability of the tasks performed by MERCURIO and the usefulness of the knowledge discovery approach, we performed a test based on a dataset of real infection events. In the validation task MERCURIO achieved an accuracy of 98.5%, a sensitivity of 98.5% and a specificity of 99%. In the therapy suggestion task, MERCURIO achieved very high accuracy and specificity as well. The executed test provided many insights to experts, too (we discovered some of their mistakes). The knowledge discovery approach was very effective in validating part of the MERCURIO knowledge base, and also in extending it with new validation rules, confirmed by interviewed microbiologists and specific to the hospital laboratory under consideration.

Economic justification of antimicrobial management programs: implications of antimicrobial resistance.

The relationship between the problem of antimicrobial resistance and efforts to control antimicrobial costs is explored. Antimicrobial drug management typically centers around controlling costs and controlling antimicrobial resistance. Selection of therapeutic alternatives without adherence to a well-developed program or without a rationale based on data from the medical literature may promote antimicrobial resistance. Attempts to select alternatives can produce cost shifting rather than cost containment. The annual cost associated with antimicrobial resistance in the United States is estimated to be as high as $47 billion. In one study, patients with bacteremia caused by methicillin-resistant Staphylococcus aureus had an average length of stay 2.7 days longer than patients with susceptible strains and a mean cost of care that was $3500 higher. Infection control is one of the most important duties of health care practitioners. Given today's prevailing reimbursement structure, hospitals with high rates of nosocomial and resistant infections are likely to lose money. A basic problem with the current approach to controlling resistance is that the two most common strategies, highly restrictive formularies and drug cycling, work in opposition. Antimicrobial management programs should be directed at ensuring the most appropriate use of antimicrobials rather than focusing on limiting choices.

Legal issues involved in academic sterilization monitoring services.

With the advent of regulatory requirements regarding infection-control procedures, the business of sterilization monitoring is becoming ever more popular across the country. Therefore, monitoring services, many of which are associated with an academic institution, are providing such services for dental practitioners. The relationship between the service and its clients, as well as the types of service the sterilization monitoring service provides, presents some interesting legal issues. The documentation of services provided, including record keeping, requires compliance with various state confidentiality and privacy laws. The service must also be concerned about potentially misrepresenting itself to its clients about the services it offers. Additionally, the service must avoid making warranties that its clients may detrimentally rely on to escape sanctions by applicable regulatory agencies. Finally, the service must concern itself with general business regulations, including those specific policies and rules that apply to the academic institution with which it is associated.

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.

Nurses' documentation of infection control precautions: 2.

A small action research study was undertaken, using a quasi-experimental approach, to establish to what extent infection control advice was documented and to assess the effectiveness of the provision of an example care plan for control of infection. The study population comprised two groups of patients colonized or infected with ALERT organisms and involved 28 wards in six hospitals. Baseline data confirmed that infection control precautions were documented for less than 25% of patients overall. Provision of an 'example' care plan, together with guidance in its use, was followed by an increase in documentation for all items audited, while identification of the infection in the care plan showed a statistically significant increase (P < 0.05). However, in spite of this apparent improvement the documentation of appropriate care for control of infection remained inadequate. It is concluded that, while various strategies to effect change are at the infection control nurse's disposal, the need to integrate infection control with practice must be addressed at every level to include managers, educators and practitioners.

Meningitis in infancy in England and Wales: follow up at age 5 years.

OBJECTIVE: To describe important sequelae occurring among a cohort of children aged 5 years who had had meningitis during the first year of life and who had been identified by a prospective national study of meningitis in infancy in England and Wales between 1985 and 1987. DESIGN: Follow up questionnaires asking about the children's health and development were sent to general practitioners and parents of the children and to parents of matched controls. The organism that caused the infection and age at infection were also recorded. SETTING: England and Wales. PARTICIPANTS: General practitioners and parents of children who had had meningitis before the age of 1 year and of matched controls. MAIN OUTCOME MEASURES: The prevalence of health and developmental problems and overall disability among children who had had meningitis compared with controls. RESULTS: Altogether, 1584 of 1717 (92.2%) children who had had meningitis and 1391 of 1485 (93.6%) controls were successfully followed up. Among children who survived to age 5 years 247 of 1584 (15.6%) had a disability; there was a 10-fold increase in the risk of severe or moderate disability at 5 years of age among children who had had meningitis (relative risk 10.3, 95% confidence interval 6.7 to 16.0, P<0.001). There was considerable variation in the rates of severe or moderate disability in children infected with different organisms. CONCLUSION: The long term consequences of having meningitis during the first year of life are significant: 32 of 1717 (1.8%) children died within five years. Not only did almost a fifth of children with meningitis have a permanent, severe or moderately severe disability, but subtle deficits were also more prevalent.

Development of national guidelines for the prevention and control of nosocomial infections.

OBJECTIVE: To develop a national evidence-based guidelines for the prevention and control of nosocomial infection. MATERIAL AND METHOD: Draft guidelines for the prevention and control of nosocomial infection were developed by the researchers and reviewed by a 10 member panel of experts. The guidelines were modified by brainstorming of 55 practitioners in July 2002. The guidelines were tested for their applicability in 20 hospitals across the country in 2002. The participants gave suggestions on the guidelines which were modified accordingly. The guidelines were finalized by brainstorming of the 55 practitioners in August 2003. RESULTS: National guidelines for the prevention and control of nosocomial infections were developed. Twenty-one topics were included. Modifications of the drafted guidelines were made four times according to the opinions of 10 experts, twice by brainstorming of 55 practitioners and by the suggestions of participants from 20 hospitals where they were tested. The practices in hospitals with different facilities were also suggested in the guidelines. CONCLUSION: National guidelines for prevention and control of nosocomial infection were formulated. Their application for use in every hospital and periodic reviews are expected.

HIV/AIDS in the classroom: ethical and legal issues surrounding the public education of the HIV-infected child.

The AIDS crisis has paralyzed the minds of many rational individuals. This paralysis of the mind unfortunately is the result of fear and ignorance. The past 10 years of the AIDS crisis has resulted in massive quantities of published reports regarding the biology, pathogenesis, transmission, clinical manifestations, and treatment of the AIDS virus. Yet there are those who still respond hysterically to the AIDS crisis. One group on which the results of much fear and ignorance have fallen is the school-aged child who is HIV infected. This article explores the issues of risk (to other school children and the HIV-infected child), the legal rights of the HIV-infected child to a public education, and the role of the pediatric nurse practitioner in the disclosure of the HIV-infected child's diagnosis.

The effects of using infection-control barrier techniques on young children's behavior during dental treatment.

This report provides a review of infection-control techniques used by health-care practitioners. It is then stated that there is an increased awareness regarding the role of nonverbal influences on the communication process, especially among child patients, for whom fear and anxiety are common traits. This study evaluated whether the use of masks in the dental operatory affected anxiety behavior, based on changes in heart rate, self-reports, and uncooperative responses. The findings here suggest that wearing a mask during dental treatment represents a minimal stressor for the young child with previous dental experience.

Infection control in general practice: results of a questionnaire survey.

BACKGROUND: Infection control is an important aspect of quality of care. General practitioners (GPs) have a high throughput of patients, some attending because of a communicable disease, others for investigations or minor operations. This situation provides an opportunity for the spread of infections. This study looked at the development of practice policies on infection control and the need for further information and guidelines. METHODS: A postal questionnaire was sent to 117 practices in a single Family Health Services Authority. The questionnaire contained sections to be completed by a GP and a practice nurse in each surgery. RESULTS: A response rate of 74.5 per cent was obtained. Of the practices replying, 85 per cent did not have a written infection control policy. Sterilization of instruments was carried out in over 90 per cent of surgeries. Autoclaves were used in almost four-fifths of these practices; most did not have any written procedures covering their use. Few practices provided information on procedures for infected patients or staff. A third of practices did not have a needlestick policy, and sharps incidents were not recorded in 42 per cent of surgeries. Three-quarters of practices said that they would welcome guidelines on infection control. Half of the practice nurses thought that more training on infection control was required. CONCLUSIONS: The need for more training and the implications of the information from the study on the development and implementation of guidelines are discussed. Recommendations are made which aim to increase the awareness of this issue by means of guidelines and training focused on practice nurses.

Survey to assess dental practitioner's knowledge of infectious disease.

The prerequisite to understanding the need for infection control practices in dentistry is a sound knowledge of infectious disease and the potential for its transmission in the dental setting. To assess the infectious disease knowledge-base of dental practitioners, a questionnaire was developed and distributed to dentists in British Columbia. The survey results showed that many of the mechanisms, routes and risks for the transmission of viral pathogens in the dental setting are not clearly understood by dentists. Continuing education is needed to ensure that compliance with current infection control recommendations, and the provision of appropriate patient care, continues to be based on a clear understanding by dentists of the mechanisms of infection. By identifying the current infectious disease knowledge-base of dentists, this survey may permit more specifically-directed continuing education programs to be offered.

The effect of reimbursement on the use of antibiotics.

OBJECTIVE: To examine the effect of a reduction on the reimbursement of drugs on the use of antibiotics by general practitioners in Denmark. DESIGN: A prospective study using a questionnaire comparing the results with a similar study 3 years before, a period with normal reimbursement. PARTICIPANTS: 553 general practitioners prescribed antibiotics for 5765 patients. MAIN OUTCOME MEASURE: Number of treated patients and choice of antibiotics. RESULTS: 7607 patients were treated in 1987 compared with 5765 in 1990, the relative number of patients treated for sinusitis, other upper respiratory tract infections, acute bronchitis, pneumonia and upper gynaecological infections was significantly less in 1990 than in 1987. Other infections, particularly those that are often diagnosed by culture or microscopy by the general practitioners themselves, increased significantly. They included tonsillitis and urinary tract infections. CONCLUSION: Reimbursement can be a very powerful tool controlling the use of antibiotics by general practitioners.
