The role of computers in preventive medicine in a rural family practice.

Five family physicians in a group practice in rural Quebec have introduced a computer system to improve the delivery of preventive medicine. In addition to billing, the computer is used mainly to recall specific groups of patients for preventive measures, to prompt the physicians to carry out certain procedures at the patient''s next visit, to indicate which procedures are required for the family members and to generate reminder letters. The physicians are conducting a randomized controlled trial to evaluate the impact of computer-generated reminder letters on patient compliance and disease prevention among families in their practice.     

The Influences of Group and Independent General Practice on Patient Care: A Comparative Study in Ontario

When the practices of four general practitioners, members of multispecialist-general practitioner salaried groups (clinic doctors) were compared with those of four independent general practitioners (solo practitioners), it was noted that: group practice patients had more office laboratory investigation and greater in-hospital consultation and referral. On the other hand, independent practitioners'' patients seemed to receive more personal attention from the doctor, a fuller explanation of diagnosis and treatment during office hours, more drug samples and more laboratory investigation in hospital.Group and independent practices are similar with respect to the rate of follow-up visits, the volume of preventive medicine, the number of radiographs and special procedures, the total number of drugs ordered, and the in-hospital formal written consultation rate and office consultation rate.The similarities between two types of practice may be a result of the interaction of group and independent practice in the same community.It is concluded that the team approach to medical care is not incompatible with independent practice.     

A practical approach for implementation of a basal-prandial insulin therapy regimen in patients with type 2 diabetes

Background

Osteopathic philosophy is consistent with an emphasis on primary care and suggests that osteopathic physicians may have distinctive ways of interacting with their patients.

Methods

The National Ambulatory Medical Care Survey (NAMCS) was used to derive national estimates of utilization of osteopathic general and family medicine physicians during 2003 and 2004 and to examine the patient characteristics and physician-patient interactions of these osteopathic physicians. All analyses were performed using complex samples software to appropriately weigh outcomes according to the multistage probability sample design used in NAMCS and multivariate modeling was used to control for potential confounders.

Results and discussion

When weighted according to the multistage probability sample design used, the 6939 patient visits studied represented an estimated 341.4 million patient visits to general and family medicine specialists in the United States, including 64.9 million (19%) visits to osteopathic physicians and 276.5 million (81%) visits to allopathic physicians. Osteopathic physicians were a major source of care in the Northeast (odds ratio [OR], 2.94; 95% confidence interval [CI], 1.42–6.08), providing more than one-third of general and family medicine patient visits in this geographic region. Pediatric and young adult patients (OR, 0.64; 95% CI, 0.45–0.91), Hispanics (OR, 0.63; 95% CI, 0.40–1.00), and non-Black racial minority groups (OR, 0.39; 95% CI, 0.18–0.82) were less likely to visit osteopathic physicians. There were no significant differences between osteopathic and allopathic physicians with regard to the time spent with patients, provision of five common preventive medicine counseling services, or a focus on preventive care during office visits.

Conclusion

Osteopathic physicians are a major source of general and family medicine care in the United States, particularly in the Northeast. However, pediatric and young adult patients, Hispanics, and non-Black racial minorities underutilize osteopathic physicians. There is little evidence to support a distinctive approach to physician-patient interactions among osteopathic physicians in general and family medicine, particularly with regard to time spent with patients and preventive medicine services.     

The impact of routine advice on smoking cessation from family physicians.

Cigarette smoking continues to be a major health problem. Therefore, physicians have been asked to advise all their patients on the hazards of smoking. A controlled trial was undertaken to measure the impact of family physicians'' advice to cigarette smokers during a routine office visit. No significant differences were found in the three measures used to determine outcome--desire to stop smoking, an attempt to stop and success in stopping--between the control and intervention groups. These results are discussed in relation to the health belief model, and suggestions are made on how to increase the impact family physicians could have on smoking cessation to their practices.     

Analysis of Guidelines for Basal-Bolus Insulin Dosing: Basal Insulin,Correction Factor,and Carbohydrate-To-Insulin Ratio

ObjectiveTo analyze and compare the underlying mathematical models for basal-bolus insulin-dosing guidelines in patients with type 1 diabetes in a retrospective controlled study.MethodsAlgebraic model-development yielded several systems of models with unknown constants, including 3 systems currently in use. These systems were compared for logic and consistency. One of these systems was the accurate insulin management (AIM) system, which we developed in the setting of our large endocrine practice. Our database consisted of retrospective clinical records for a 7-month period. During this time, correction factor (CF), carbohydrate-to-insulin ratio (CIR), and basal insulin were being adjusted incrementally by titration. The variables studied were height, body weight in pounds (BWlb), CF, CIR, hemoglobin A1c (A1C), basal insulin, and 6-day mean total daily dose of insulin (TDD). The values of the variables used in the study were those determined on arrival of the patients at the office. The last 6 TDDs were entered into the database, and the mean was calculated by formulas within the database. We sorted our database into 2 groups, a well-controlled test group (n = 167; A1C ≤ 7%, time on pump > 180 days, no severe hypoglycemic events since the last office visit, and C-peptide level ≤ 0.5 ng/mL) and a control group with poor control (n = 209; A1C > 7% or time on pump < 180 days). We obtained one office visit per patient, as follows: from the test group, we chose the visit with the lowest A1C value; from the control group, we chose one visit by use of a computer’s random number generator. A significant difference was demonstrated between the correlation constants of the test group versus the control group by performing T tests between the means and F tests between the standard deviations. The least squares estimates of the correlation constants from the test group were recommended in the guidelines, in place of the means, to gain accuracy. By these methods, the guidelines used by the patients with good glycemic control are made available for all patients.ResultsWith use of the AIM system, the TDD for continuous subcutaneous insulin infusion = 0.24 * BWlb; basal insulin = 0.47 * TDD; CF = 1,700/TDD; and CIR = 2.8 * BWlb/TDD.ConclusionThree mathematical models for CIR are presented, with a rationale for supporting one of them (the AIM model). This model, together with 3 related AIM models, when provided with statistically correlated constants, constitutes the AIM system of guidelines, a consistent and convenient means of estimating insulin-dosing variables for patients with type 1 diabetes.

Public Awareness and Knowledge of Neglected Tropical Diseases (NTDs) Control Activities in Abuja,Nigeria

The need to engage the public in Neglected Tropical Diseases (NTDs) control activities has become imperative in the context of morbidity reduction through preventive chemotherapy and community participation. Therefore, a survey was conducted among the general public to assess their knowledge and awareness of NTDs control activities in Nigeria. A simple questionnaire was administered to the general public attending a job fair in Abuja, Nigeria. Of the 461 respondents, a significant proportion 337 (73.1%) have heard of NTD before, but only 291 (63.1%) have good knowledge about NTDs. However, among the specific NTDs, only the control of onchocerciasis (50.8%) was of average public awareness in Nigeria, while all the other NTDs control activities were significantly less known to the general public. 397 (87.1%) stated that government support for NTD control activities is poor and were willing to assist to advocate for NTDs control. This survey demonstrates that despite government''s numerous activities towards the control of NTDs in Nigeria, there is little sensitization of the general public. There is a need for policy changes that would raise the participation and involvement of the general public in NTDs control activities for sustainability.     

Determining the impact of community awareness-raising activities on the prevention of malaria transmission in Palawan,the Philippines

Palawan has the highest malaria endemicity in the Philippines, and malaria remains a major health burden in the region. In 1999, 344 microscopists were trained in Palawan. This allowed for early diagnosis and prompt treatment throughout the island. To take a significant step toward the elimination of malaria on the island, microscopists implemented community awareness-raising activities aimed at preventing transmission of malaria. The objective of the present study was to determine the impact of these activities on the self-implemented preventive measures against malaria by the ex-patients of the microscopists. Structured interviews were carried out from January to February in 2012, in 20 remote malaria-endemic villages throughout Palawan. In total, 141 ex-patients who had previously been diagnosed malaria-positive by the microscopists, volunteered to participate in the present study. Structural equation modeling was conducted to determine factors associated with self-implemented preventive measures against malaria, which included: (1) place of residence; (2) socio-demographic characteristics; (3) knowledge on malaria; (4) participation in community awareness-raising activities for malaria prevention; and (5) satisfaction with microscopists. Structural equation modeling identified six significant factors independently associated with self-implemented preventive measures against malaria; ethnicity, knowledge on malaria transmission, knowledge on vector species, knowledge on vector's most active time, participation in awareness-raising activities for malaria prevention by microscopists, and satisfaction with microscopists. Tagalog ethnicity (the predominant ethnic group) was positively related to better self-implemented preventive measures. In conclusion, aside from providing early diagnosis and treatment, microscopists played a significant role in self-implemented preventive measures against malaria. The strengthening of awareness-raising activities by microscopists was suggested to be an effective strategy for reducing malaria re-infection in Palawan. These activities should be strengthened to improve preventive measures implemented by ex-patients traveling to mountain areas and to enhance the knowledge on malaria transmission particularly among indigenous residents.     

Provision of preventive care to unannounced standardized patients

OBJECTIVE: To examine the relation between physician, training and practice characteristics and the provision of preventive care as described in the guidelines of the Canadian Task Force on the Periodic Health Examination. DESIGN: Cross-sectional study. SETTING: Family practices open to new patients within 1 hour''s drive of Hamilton, Ont. PARTICIPANTS: A total of 125 family physicians were randomly selected from respondents to an earlier preventive care survey. Of the 125, 44 (35.2%) declined to participate, and an additional 19 (15.2%) initially consented but later withdrew when they closed their practices to new patients. Sixty-two physicians thus participated in the study. INTERVENTION: Unannounced standardized patients posing as new patients to the practice visited study physicians'' practices between September 1994 and August 1995, portraying 4 scenarios: 48-year-old man, 70-year-old man, 28-year-old woman and 52-year-old woman. OUTCOME MEASURES: Proportion of preventive care manoeuvres carrying grade A, B, C, D and E recommendations from the Canadian Task Force on the Periodic Health Examination that were performed, offered or advised. A standard score was computed based on the performance of grade A and B manoeuvres (good or fair evidence for inclusion in the periodic health examination) and the non-performance of grade D and E manoeuvres (fair or good evidence for exclusion from the periodic health examination). RESULTS: Study physicians performed or offered 65.6% of applicable grade A manoeuvres, 31.0% of grade B manoeuvres, 22.4% of grade C manoeuvres, 21.8% of grade D manoeuvres and 4.9% of grade E manoeuvres. The provision of evidence-based preventive care was associated with solo (v. group) practice and capitation or salary (v. fee-for-service) payment method. Preventive care performance was unrelated to physician''s sex, certification in family medicine or problem-based (v. traditional) medical school curriculum. CONCLUSIONS: Preventive care guidelines of the Canadian Task Force on the Periodic Health Examination have been incompletely integrated into clinical practice. Research is needed to identify and reduce barriers to the provision of preventive care and to develop and apply effective processes for the creation, dissemination and implementation of clinical practice guidelines.     

Preventive practice among primary care physicians in British Columbia: relation to recommendations of the Canadian Task Force on the Periodic Health Examination.

OBJECTIVES: To compare the current practice of preventive medicine in British Columbia with the recommendations of the Canadian Task Force on the Periodic Health Examination. Four common, preventable forms of cancer (cervical, breast, lung and colorectal) were used as sentinel conditions. DESIGN: Random sample mailed survey. SETTING: Private primary care practices in British Columbia. PARTICIPANTS: A sample of 300 primary care physicians in 1991; of 285 eligible physicians 185 (65%) responded. OUTCOME MEASURE: Compliance with preventive practices recommended by the task force. RESULTS: Preventive practice complied with the task force''s recommendations for breast examinations, mammography, cervical smears and initial counselling against smoking; over 90% of the physicians performed these manoeuvres in all or most cases. However, less than half performed two recommended manoeuvres for all or most patients who smoke: advice to follow a diet high in beta-carotene (reported by 10%) and scheduling of follow-up visits to reinforce antismoking counselling (by 46%). Most of the physicians stated that they perform preventive manoeuvres in the context of an annual general physical examination rather than integrating them into routine patient care. CONCLUSIONS: The task force''s carefully constructed recommendations are incompletely followed. Overall, there appears to be a high level of compliance with traditional and recommended manoeuvres but also widespread persistence in performing traditional manoeuvres no longer recommended and failure to adopt new recommendations.     

Prescriptions for medical research. I--Management within the Medical Research Council.

In their submission to the government in advance of the white paper on science policy in the United Kingdom the Medical Research Council commends the MRC''s own approach to managing directly funded research. But a series of semi-structured interviews with the directors of some of the MRC''s units suggests a gap between the MRC''s model of managed research and the reality. Although such units are theoretically managed from MRC head office (and units are charged an overhead for this), in practice each unit runs its own affairs. Between major reviews average contact time with the head office contact person is seven hours a year. The first paper argues that a purchaser-provider split would recognise the benefits of decentralisation and allow units to bid for research funds from several sources, the successful ones guaranteeing their survival through a rolling series of research programmes. The second paper criticises the MRC''s cumbersome peer review system. Reliance on outside experts atrophies the scientific skills of head office staff and builds delays into decision making. A purchaser-provider model would allow the head office scientific staff to act like commercial research and development managers, commissioning research, and using the outcome, rather than peer review, as a criterion for continued funding.     

Professional Dental Care for Patients with Dementia

Individuals with dementia present a significant challenge to the dental professional. The dental professional must meet the special needs of the patient with dementia with patience and a variety of non-traditional skills, including treatment planning with caregivers and nonverbal communication to reassure disoriented patients. The goals of dental care for the patient with dementia are to restore and maintain oral health and prevent progression of oral disease. Because of the degenerative nature of dementia, the first dental visit for a patient with dementia may represent the patient's best cognitive functioning level. For this reason, the dental treatment plan should aim to restore oral function quickly and to institute an intensive preventive program. Practical guidelines for preventive diagnostic, and restorative care are provided. To illustrate these points, two cases are presented.     

Nurse practitioners in primary care III. The southern Ontario randomized trial

A group of nurses who formerly had performed office functions received a special university-based educational program designed to prepare them to assume much of primary care management as nurse practitioners. The associated family physicians would shift their role to general supervision and attention to difficult clinical problems. To test this new form of practice, two complementary randomized trials have been conducted in south-central Ontario. The particular trial reported here was intended to assess the influence of the educational program on the changing roles of the professional personnel. The nurses of 14 family medical practices, with the physicians'' support and commitment to participation, applied for the new training. Seven applicants were randomly selected to receive the training and their corresponding practices became the experimental group, while the remaining nurses and practices were retained as controls. During the subsequent year of investigation important changes occurred in professional roles of the experimental group. Nurse practitioners spent more time in clinical activities than conventional office nurses. The shift was not at the expense of time devoted to clinical work by physicians. Doctors delegated more professional activities to nurse practitioners than to conventional nurses. Except for remuneration (affected by legal constraints) job satisfaction among experimental physicians and nurses remained high after one year of experience with the new method.     

Guidelines to birth control counselling of the physically handicapped.

Birth control counselling of well motivated physically handicapped men and women is discussed in a series of suggested steps: (1) preappointment arrangements are made to ensure physical access to the office, and the partner or a helper may be invited to the visit; (2) the patient is encouraged to name the desired birth control method; (3) the patient''s fertility is established from the history and the results of physical examination and laboratory tests; (4) methods of birth control are matched to the patient''s physical and mental capabilities; (5) potential side effects of the proposed methods are considered in the light of the handicap; (6) a method is finally recommended that may be a trade-off, with ease of use balanced against efficacy, and living with side effects balanced against the risks of pregnancy; and (7) rechecks are necessary to ensure that the patient is using the method with skill and satisfaction.     

Postal survey of patients' satisfaction with a general practice out of hours cooperative.

OBJECTIVE: To assess patients'' satisfaction with out of hours care by a general practice cooperative compared with that by a deputising service. DESIGN: Postal questionnaire survey. SETTING: A general practice cooperative in London and a deputising service operating in an overlapping area. SUBJECTS: Weighted samples of patients receiving telephone advice, a home visit, or attending a primary care centre after contacting either service in an eight week period. MAIN OUTCOME MEASURES: Patients'' overall satisfaction and scores for specific aspects of satisfaction. Satisfaction with telephone advice or attendance at centre compared with home visit. Relation between satisfaction and patient''s age, sex, ethnic group, car ownership, preference for consulting own doctor, and expectation of a visit. RESULTS: The overall response rate was 67% (1555/2312). There was little difference in overall satisfaction between patients contacting the cooperative or the deputising service, but patients contacting the latter were less satisfied with the explanation and advice received and the wait for a visit. There were significant differences between patients in different age and ethnic groups, with white patients and those aged over 60 years being more satisfied. Lower scores for overall satisfaction were reported by patients who received telephone advice, those who would have preferred to see their own doctor or who originally wanted a home visit, and those who waited longer for their consultation. Overall levels of patients'' satisfaction seemed to be lower than previously reported. CONCLUSIONS: There were larger differences in satisfaction between different groups of patients than between different models of organisation for out of hours care. A shift to a service based predominantly on telephone advice may lead to increased patient dissatisfaction.     

Prevention in practice: what Wessex general practitioners are doing.

A random sample of 214 general practitioners in the Wessex region was invited to complete a postal questionnaire about the practice of preventive medicine and 90% replied. This inquired into their attitude and behaviour towards smoking and accident prevention, promoting exercise, and controlling obesity and hypertension. The results were generally encouraging. Most recognised their key role in health promotion and health education and their shared responsibility with other professionals. Many had made progress in smoking prevention and control of obesity and hypertension. Promoting exercise and accident prevention left room for improvement. The availability of information in patients'' records to identify and monitor problem areas was particularly lacking. We conclude that further progress might be achieved by better training of general practitioners, and developing information systems orientated towards promoting health. The team approach in primary care needs to be strengthened. In particular extending the role of the health visitor and practice nurse may provide the support so vital for the successful outcome of preventive initiatives. Community unit management teams need to consider carefully how they may encourage advances in health promotion in primary care.     

Ionizing Radiation as an Industrial Health Problem

Ionizing radiation, first as x-rays, later in natural form, was discovered in Europe in the late 1890''s. Immediate practical uses were found for these discoveries, particularly in medicine. Unfortunately, because of the crude early equipment and ignorance of the harmful effects of radiation, many people were injured, some fatally. Because of these experiences, committees and regulatory bodies were set up to study the problem. These have built up an impressive fund of knowledge useful in radiation protection.With the recent development of the peaceful uses of atomic energy, sources of radioactivity have appeared cheaply and in abundance. A rapidly growing number are finding industrial application. Because of their potential risk to humans, the industrial physician must acquire new knowledge and skills so that he may give proper guidance in this new realm of preventive medicine.The Radiation Protection Program of one such industry, the Hydro-Electric Power Commission of Ontario, is summarized.
