The American General Practitioner in Hospital

In the U.S.A. and Canada full access of general practitioners to hospital beds and facilities is regarded as an essential privilege of their work. All hospital constitutions require a review of the credentials of staff applicants and continuing evaluation of their performance. Staff appointment carries administrative as well as clinical responsibilities and hospital work occupies a considerable proportion of the general practitioner''s day. The disciplinary machinery for safeguarding standards is strict by comparison with British hospital practice.This system produces an obvious excellence of clinical standards, postgraduate education, and communication between specialist and general practitioner and is attractive to the more able young British graduate. A pilot experiment of hospital staffing on North American lines in one of our new district general hospitals would be a worthwhile proposition.     

Hormone replacement therapy: a survey of Ontario physicians' prescribing practices

BACKGROUND: Although much has been written about hormone replacement therapy (HRT), there are few clearcut recommendations on its use. The purpose of this study was to determine Ontario physicians'' patterns of and reasons for prescribing HRT, their use of pretreatment investigations and their surveillance of HRT users, and to determine whether physicians'' reported practice is consistent with existing recommendations. METHODS: A self-administered questionnaire was mailed to a nonproportional stratified sample of 327 Ontario physicians (23.9% gynecologists, 76.1% general practitioners/family physicians [GP/FPs]). Outcome measures were ranking of reasons for prescribing HRT, nature of preliminary testing, regimens prescribed, duration of HRT and frequency of follow-up. RESULTS: The response rate was 60.9% overall (70.9% of the gynecologists, 58.3% of the GP/FPs). Prevention of osteoporosis was reported by 97.4% as an important or very important reason for prescribing HRT; prevention of coronary artery disease was important or very important for 89.3%. When considering whether or not to prescribe HRT, 97.3% stated that breast cancer was an important or very important factor. When presented with hypothetical cases, 97.0% stated that they would prescribe combined estrogen-progestin for a symptomatic woman with an intact uterus; 13.6% stated that they would do so for a woman with no uterus. Most reported that they would prescribe HRT for 12 or more years (73.3%) and would follow up patients every 1 to 2 years (70.6%). INTERPRETATION: Despite controversy about HRT in the published literature, the Ontario physicians surveyed reported similar reasons and patterns of prescribing, pretreatment investigations, and surveillance of postmenopausal women using HRT. These results suggest that Ontario physicians'' knowledge about HRT is consistent with recommendations in the published literature.     

新冠肺炎疫情防控背景下医院文化建设的思路与方法探析

摘要：随着疫情的不断蔓延，新冠肺炎目前已成为全球范围内共同关注的重大公共问题。新冠肺炎疫情出现之后，医院广大医务人员积极响应党和国家的号召，义无反顾地投入疫情防控"战役"之中，将救死扶伤以及大爱无疆等新时代医疗卫生职业精神内化成"抗疫精神"；该精神不但反映了医务人员的责任以及担当，而且是医院可持续发展的有效动力，更是医院文化建设的关键内容。医院文化主要是指各级医疗机构在开展医疗工作过程中潜移默化所形成的一种特殊文化氛围和价值观，不仅在公共卫生体系中占据重要地位，同时可能直接或间接影响医院长期竞争力的发展。尤其是在目前新冠肺炎疫情防控之中，文化建设可发挥着特殊的作用，有效提高服务效率以及服务质量。本文结合疫情防控背景下的医院相关疫情防控措施，探析医院抗疫文化建设的思路和策略，以提高医院品牌形象以及业内影响力，继而促进医院整体文化建设的更深、更高层次发展。     

Effect of computer use in the consultation on the delivery of care.

The effects of the use of a computer on the delivery of care in consultations in general practice were examined. In this trial a computer system provided for the review and update of patients'' medical histories, notes on doctor-patient contacts, and information on repeat prescribing. Thirty consultations in which the computer system was used and 30 consultations in which no computer was used were matched individually for the doctor consulted, the sex and age of the patient, and the presenting problem(s). Six independent general practitioners blind rated each consultation for the standard of care attained. A minor negative effect of computer use on the doctors'' clinical performance was found. We suggest, however, that this small effect would disappear if a computer system was used routinely.     

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.     

What Is So Special About a Family Physician?

Around a core of common, acute and chronic, recurrent health problems, a family physician must marshall the traditional episodic management for both inpatient and outpatient illness. He must also be especially adept at recently emerging routines of prevention and early detection. He provides individual and familial psychologic support and counselling, for both its therapeutic and preventive values. In addition, he must relate the individual care of his patient and the patient''s family to the community as a whole. In doing this he will use not only his own skills but those of lay health volunteers, trained allied health care professionals and skilled subspecialists in the limited medical disciplines.The proper preparation of family physicians for this complicated role has far-reaching implications for change in both medical education and medical practice.     

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.     

Care of the diabetic child in the community.

Brief admission of the new diabetic child and of a parent to an enlightened hospital for stabilisation, preliminary education, and familiarisation with hospital and community staff is well worth while. The greater the demand for constant control of the highest quality, the greater the need for a close understanding of the psychosocial factors concerned and for clinical skill. The nature of the home and the family relationships should in theory be available from the child''s general practitioner at the time of the first referral since he has so much information about the whole family. With the virtual disappearance, however, of mutual consultation in the patient''s home in many places, the opportunity for oral communication has declined, and availability on the telephone is not always easy. The busy general practitioner (far less an unknown physician from a deputising service without access to the records) has little time to write a comprehensive letter. In practice a relatively small hospital-based mobile team of specially experienced sisters who are keen to communicate in the home, the GP''s surgery, and the school makes a major contribution to the diabetic care of a young population vulnerable to major handicap in what should be the prime of life. Their cost effectiveness may be difficult to prove but it is not at all in doubt--especially when the sisters as in this area deal in the community with a wider range of chronic illnesses and handicaps in children.     

Decreases in Community Viral Load Are Accompanied by Reductions in New HIV Infections in San Francisco

Background

At the individual level, higher HIV viral load predicts sexual transmission risk. We evaluated San Francisco''s community viral load (CVL) as a population level marker of HIV transmission risk. We hypothesized that the decrease in CVL in San Francisco from 2004–2008, corresponding with increased rates of HIV testing, antiretroviral therapy (ART) coverage and effectiveness, and population-level virologic suppression, would be associated with a reduction in new HIV infections.

Methodology/Principal Findings

We used San Francisco''s HIV/AIDS surveillance system to examine the trends in CVL. Mean CVL was calculated as the mean of the most recent viral load of all reported HIV-positive individuals in a particular community. Total CVL was defined as the sum of the most recent viral loads of all HIV-positive individuals in a particular community. We used Poisson models with robust standard errors to assess the relationships between the mean and total CVL and the primary outcome: annual numbers of newly diagnosed HIV cases. Both mean and total CVL decreased from 2004–2008 and were accompanied by decreases in new HIV diagnoses from 798 (2004) to 434 (2008). The mean (p = 0.003) and total CVL (p = 0.002) were significantly associated with new HIV cases from 2004–2008.

Conclusions/Significance

Reductions in CVL are associated with decreased HIV infections. Results suggest that wide-scale ART could reduce HIV transmission at the population level. Because CVL is temporally upstream of new HIV infections, jurisdictions should consider adding CVL to routine HIV surveillance to track the epidemic, allocate resources, and to evaluate the effectiveness of HIV prevention and treatment efforts.     

Ocean surveillance technologies and International payoffs

Abstract

This paper discusses the evolution of the existing ocean surveillance technologies and the many new devices in the field. Among the systems dealt with is “Project Seaguard”; of the U.S. Defense Advanced Research Project Agency and its ILLIACIV, the world's largest computer, which coordinates sensor data from 64 worldwide inputs. The author visualizes important future uses of underwater listening devices and ocean monitoring networks for solely peaceful purposes, as, for instance, by warning endangered ships of all nations of hurricanes, tsunamis, and icebergs. More accurate and comprehensive surveys of fishing efforts, pollution prevention, and customs enforcement may also be carried out by the use of present and future technologies. In conclusion, the author proposes the creation of a Global Ocean Management Organization, whose services would greatly beenfit all member states and might even serve as a model for systems verifying multilateral disarmament agreements and the monitoring of crises.     

Physician time-saving by employment of expanded-role nurses in family practice

Registered nurses working in five family practices in Kingston, Ontario, were given a period of in-service training and supplementary formal instruction at Queen''s University to expand their skills and enable them to undertake prescribed procedures in the physicians'' offices. Operational data collected from the five practices before and after training was analysed to assess the saving of physician time effected by the expansion of the nurses'' activities in providing primary medical care. Physician time was saved in all cases but the amount varied. The results are presented and discussed in relation to staff, physical premises and patterns of practice of the participating physicians. Under the most advantageous practice circumstances in this study, a 33.7% saving in original physician time was obtained. The mean time-saving for the five practices was 18.2%.     

Challenges of maintaining research protocol fidelity in a clinical care setting: A qualitative study of the experiences and views of patients and staff participating in a randomized controlled trial

Background

Trial research has predominantly focused on patient and staff understandings of trial concepts and/or motivations for taking part, rather than why treatment recommendations may or may not be followed during trial delivery. This study sought to understand why there was limited attainment of the glycaemic target (HbA_1c ≤6.5%) among patients who participated in the Treating to Target in Type 2 Diabetes Trial (4-T). The objective was to inform interpretation of trial outcomes and provide recommendations for future trial delivery.

Methods

In-depth interviews were conducted with 45 patients and 21 health professionals recruited from 11 of 58 trial centres in the UK. Patients were broadly representative of those in the main trial in terms of treatment allocation, demographics and glycaemic control. Both physicians and research nurses were interviewed.

Results

Most patients were committed to taking insulin as recommended by 4-T staff. To avoid hypoglycaemia, patients occasionally altered or skipped insulin doses, normally in consultation with staff. Patients were usually unaware of the trial's glycaemic target. Positive staff feedback could lead patients to believe they had been 'successful' trial participants even when their HbA_1c exceeded 6.5%. While some staff felt that the 4-T automated insulin dose adjustment algorithm had increased their confidence to prescribe larger insulin doses than in routine clinical practice, all described situations where they had not followed its recommendations. Staff regarded the application of a 'one size fits all' glycaemic target during the trial as contradicting routine clinical practice where they would tailor treatments to individuals. Staff also expressed concerns that 'tight' glycaemic control might impose an unacceptably high risk of hypoglycaemia, thus compromising trust and safety, especially amongst older patients. To address these concerns, staff tended to adapt the trial protocol to align it with their clinical practices and experiences.

Conclusions

To understand trial findings, foster attainment of endpoints, and promote protocol fidelity, it may be necessary to look beyond individual patient characteristics and experiences. Specifically, the context of trial delivery, the impact of staff involvement, and the difficulties staff may encounter in balancing competing 'clinical' and 'research' roles and responsibilities may need to be considered and addressed.

     

The dental informatics online community

Dental Informatics (DI) is the application of computer and information science to improve dental practice, research, education, and program administration. To support the growth of this emerging discipline, we created the Dental Informatics Online Community (DIOC). The DIOC provides a dedicated professional home for DI researchers and serves as an open, common, and worldwide forum for all individuals interested in the field. It was created and is maintained by the Center for Dental Informatics at the University of Pittsburgh School of Dental Medicine, independent from any professional association, corporate interest or funding source. The DIOC''s Website provides many useful features, such as a learning center, publication archive, member and project directories, and the Current Awareness Service (CAS). The CAS automatically notifies members about new information added to the Community. Notifications are individualized according to a member''s profile and activities on the site. The DIOC is a research-oriented online community which provides resources in the dental informatics and dental technology field, as well as a way to establish social connections to share ideas, problems and research opportunities. Member and activity growth since the community''s inception in 2005 have been steady, but future sustainability of the community depends on many factors.     

Cost of achieving a balance in the anaesthetic department of a district general hospital.

In Achieving a Balance the Department of Health published requirements for medical staffing in hospitals. To review the effect that these would be likely to have a study was undertaken in the anaesthetic department of a district general hospital. The results were then validated with staffing levels in a new district general hospital with only one tier of junior staff. It was found that over the next 10 years a massive expansion in the numbers of consultants would be needed at a cost of 108,000 pounds in salaries and employer''s contributions alone.     

Comparison of parents' expectations and importance ratings for specific aspects of childbirth.

We examined parents'' expectations of many aspects of the birth experience and compared them with the importance they attached to these aspects. Expectation was defined as a respondent''s rating that a given practice would be reality, and importance was defined as a respondent''s rating of the personal importance of a practice were all options possible. Subjects in the last 6 to 8 weeks of pregnancy were asked by their obstetricians to complete a questionnaire; 231 mothers and 227 fathers responded, for a response rate of 95%. In each of six subcategories parents'' importance ratings significantly exceeded their expectation ratings. Certain items were rated as relatively less important postnatally than prenatally and by multigravid women than by primigravid women. Parents'' perceptions of available options reflect consistent discrepancy with what they wish were possible. However, increased efforts to inform parents of existing options and to provide the rationale for specific practices may reduce the discrepancy between importance and expectations. This would in turn heighten the likelihood of a psychologically positive birth experience for parents.     

Colposcopy in a family planning clinic: a future model?

The first year''s experience of a satellite colposcopy clinic in the Glasgow Family Planning Centre was analysed. Establishment of the clinic was supervised by an experienced member of the colposcopy team at the department of gynaecology, Western Infirmary, Glasgow, who trained one of the family planning centre''s staff. Close links were thus maintained with the hospital clinic to which patients were referred for treatment. The policy at the new colposcopy clinic was to study prospectively all women in the hospital catchment area whose cervical smears were reported as abnormal. In 58 of 162 such patients there was at least moderate dyskaryosis and the cytologist''s recommendation had been referral for colposcopy. In 104 cases the changes were either atypia alone or mild dyskaryosis and a repeat smear was recommended within three to 12 months; 18 of these patients had grade II or III cervical intraepithelial neoplasia on biopsy, and relying on repeat smears would have resulted in an 11.7% false negative rate. If an atypical cytological picture is to be an indication for colposcopy clinics attached to family planning centres may have an important role, given satisfactory training and close links with central specialist colposcopy clinics.     

Neuroplasticity. Key to recovery after central nervous system injury.

After an injury to the central nervous system, physical and cognitive impairments and disabilities often abate. These gains may be partly mediated by mechanisms that allow reorganizing of the structure and function within gray and white matter. The potential to enhance neurologic recovery by manipulating the brain and spinal cord must now be considered in clinical practice. Today''s rehabilitation routines may not encourage maximum recovery. Indeed, some commonly used physical and pharmacologic methods could inhibit the restoration of motor activities such as walking. On the other hand, therapies that use our expanding knowledge of neuroplasticity could lead to better results for patients.     

Outpatients: can we save time and reduce waiting lists?

The amount of time that one consultant urologist wasted on unnecessary administration while seeing outpatients was noted over six weeks. Searching for missing clinical data and the time spent on non-medical clerical tasks took up nearly half of the consultant''s sessions. This seemed to be due to insufficient clerical and secretarial staff. Because low salaries are offered to such staff vast sums of money are being paid to agencies who are providing an appreciable number (40%) of the secretarial staff in our hospitals.Urgent action from the government is needed to remedy this and thus make substantial reductions in outpatient waiting lists nationally. It would greatly improve morale in this important sector of the health service without increasing total costs.     

A total audit of preventive procedures in 45 practices caring for 430,000 patients.

OBJECTIVE--To develop and report the results of a system of audit of computer records in general practice. DESIGN--A retrospective audit of records in practices using the same computer system. Information about recorded preventive procedures was collected by sending the same audit program to each practice on floppy disk. Other characteristics of the practices were determined by postal questionnaire. SETTING--Forty five general practices, widely distributed in England and Wales. SUBJECTS--All 430,901 patients registered with the practices. MAIN OUTCOME MEASURES--Within each practice the percentage of patients in specified age groups for whom certain preventive procedures were recorded as having been carried out. These measures were analysed in relation to practice characteristics. RESULTS--Practice characteristics and recording rates for preventive procedures varied over a wide range. Recording rates were higher in practices with computer terminals on every doctor''s desk. Only one practice achieved the new contract target of 90% coverage for recorded primary immunisations, and fewer than two thirds recorded 80% coverage for cervical cytology in the past five years. Practices holding clinics did no better than those without. Smaller partnerships and smaller doctors'' list sizes were associated with better performance. CONCLUSIONS--Centrally programmed audit of computerised records is a feasible method of providing data on a regular basis for epidemiological purposes and for performance review. The fact that practices with smaller list sizes had higher levels of recorded preventive care suggests that the trend towards larger lists promoted by the new contract might militate against the intended effect of better preventive care.
