List size,screening methods,and other characteristics of practices in relation to preventive care.

Twenty eight practices carried out a review of patient records for information about preventive procedures on two occasions in 1980 and 1982. We have now undertaken a survey of certain characteristics of the practices in an attempt to demonstrate features associated with effective preventive care. Significant favourable factors are a small list size, the setting up of a formal screening programme for cervical cytology and measuring blood pressure, and few registered patients in social classes IV and V. More successful practices also tend to be training practices, have principals with higher qualifications, and have developed good records organization. Opportunistic screening for cervical cytology and measuring blood pressure was not shown to be more effective than no policy of screening at all.     

Survey of general practice audit in Leeds.

OBJECTIVE--To determine general practitioners'' attitudes to medical audit and to establish what initiatives are already being undertaken; to define future ideas for audit and perceived difficulties in implementing audit in primary care. DESIGN--Analysis of responses to a self administered postal questionnaire. SETTING--Urban conurbation with a population of about 750,000. PARTICIPANTS--386 general practitioners on the general medical list of Leeds Family Practitioner Committee. MAIN OUTCOME MEASURES--Extent of recording of practice activity data and outcome measures and clinical data, use of data, and audit performed; ideas for audit and perceived difficulties. RESULTS--317 doctors responded to the questionnaire (individual response rate 82%) from 121 practices (practice response rate 88%). In all, 206 doctors thought that audit could improve the quality of care; 292 collected practice activity data, though 143 of them did not use it. A total of 111 doctors recorded some outcome measures, though half of them did not use them. Varying proportions of doctors had registers, for various diseases (136 had at least one register), disease management policies (60 doctors), and prescribing policies. In all, 184 doctors met monthly with other members of the primary health care team. CONCLUSIONS--Much poorly focused data collection is taking place. Some doctors have experience in setting up basic information systems and practice policies, and some audit is being performed. The family health services authorities need to take seriously the perceived difficulties of time, organisation, and resources concerned with audit.     

Maintaining the accuracy of a computer practice register: household index

In this practice, with a family practitioner committee list of 9726 patients, we use a computer register for recall, screening, morbidity data, audit, and repeat prescribing. The computing techniques used to achieve accuracy in maintaining the register are described. After one year of full use the register was validated by using the computer to select a random sample of 200 patients from patients'' computer records that had not been updated recently. Two patients were untraceable, and in only 11 records were errors of information found, none of which was important. We think that it is feasible and valuable to have a household index.     

Auditing audits: use and development of the Oxfordshire Medical Audit Advisory Group rating system.

OBJECTIVES--To assess the value of the Oxfordshire Medical Audit Advisory Group rating system in monitoring and stimulating audit activity, and to implement a development of the system. DESIGN--Use of the rating system for assessment of practice audits on three annual visits in Oxfordshire; development and use of an "audit grid" as a refinement of the system; questionnaire to all medical audit advisory groups in England and Wales. SETTING--All 85 general practices in Oxfordshire; all 95 medical audit advisory groups in England and Wales. MAIN OUTCOME MEASURES--Level of practices'' audit activity as measured by rating scale and grid. Use of scale nationally together with perceptions of strengths and weaknesses as perceived by chairs of medical audit advisory groups. RESULTS--After one year Oxfordshire practices more than attained the target standards set in 1991, with 72% doing audit involving setting target standards or implementing change; by 1993 this had risen to 78%. Most audits were confined to chronic disease management, preventive care, and appointments. 38 of 92 medical audit advisory groups used the Oxfordshire group''s rating scale. Its main weaknesses were insensitivity in assessing the quality of audits and failure to measure team involvement. CONCLUSIONS--The rating system is effective educationally in helping practices improve and summatively for providing feedback to family health service authorities. The grid showed up weakness in the breadth of audit topics studied. IMPLICATIONS AND ACTION--Oxfordshire practices achieved targets set for 1991-2 but need to broaden the scope of their audits and the topics studied. The advisory group''s targets for 1994-5 are for 50% of practices to achieve an audit in each of the areas of clinical care, access, communication, and professional values and for 80% of audits to include setting targets or implementing change.     

Impact of audit on preventive measures.

The results of two reviews of practice records for information about various preventive measures are reported. The reviews were conducted two and a half years apart in the same 29 practices, on roughly 6500 records on each occasion. The first review was carried out during a postgraduate education course involving audit. Two main analyses were undertaken: one concerned with the entire record sample and the other with the individual practice results. Important and substantial improvements were shown in both analyses, which were spread throughout the practices and were not confined to practices at the lower end of the range simply "catching up." The change between the reviews in the mean recorded rates for cervical cytology was 56% to 64%; for rubella immunity 28% to 40%; for polio immunity in adults 15% to 21%; for completed primary immunisation 68% to 78%; for recorded blood pressure 53% to 61%; and for smoking information 22% to 30%. Improvement has been steady but the rate of improvement, especially for recording blood pressure and rubella immunity, has increased since the postgraduate education course.     

How can good general practitioner care be achieved?

It has been shown that to provide a high standard of care general practitioners probably need to book consultations at intervals of at least 10 minutes. In this study the maximum list size for which a general practitioner might be expected to provide a high standard of care was determined from calculations of the time spent consulting, based on various consultation rates and list sizes and assuming that consultations were 10 minutes long. If good quality care is to be provided and is to include the range of services suggested in the government''s recent green paper average list sizes should probably be no more than 1750, and lower in areas of high demand and high need. In addition to this, minimum standards could be determined for such measures as facilities available in surgeries, practice records, and accessibility of doctors to ensure that basic services were offered by all general practitioners.     

Cervical screening in Perth and Kinross since introduction of the new contract.

OBJECTIVE--To determine changes in the cervical screening service since the introduction of the new general practitioner contract on 1 April 1990. DESIGN--Analysis of computerised records of cervical screening both before and after introduction of the new contract. SETTING--General practices in Perth and Kinross Unit, Tayside. PATIENTS--A total of 30,071 women aged 21-60 on 26 general practitioner partnership lists. MAIN OUTCOME MEASURES--Percentage average of target population for cervical screening in each practice for first three quarters on introduction of the contract. RESULTS--Perth and Kinross Unit completed a computerised cervical screening call programme in July 1989, which produced an increase from 71% to 78% in the mean percentage of women aged 20-60 who had had cervical smear tests within 5.5 years. Six months after the introduction of the new general practitioner contract the mean population coverage was increased to 85% in women aged 21-60 and only four practices had not attained the 80% upper target compared with 10 on 1 April 1990. Detailed examination of randomly selected practices immediately before the new contract was introduced showed an average artificial list inflation of 4.3% in health board records when compared with practice records, a hysterectomy rate of 6.2%, and an additional 3% of women who were considered to be ineligible for smear testing due to putative virginity or illness or infirmity, or both. There was a considerable shift away from use of well woman clinics (2.7% of smears in 1990 compared with 5.6% in 1988) for taking cervical smears, potentially threatening the long term viability of the clinics. CONCLUSION--The introduction of the new contract for general practitioners has brought about a further sustained increase in population coverage for cervical screening in a small Scottish unit with a stable population, well motivated general practitioners, and a fully integrated computerised call and recall system based on the community health index. To optimise the screening service revision of the targets levels is necessary.     

Fundholding in general practice and financial risk.

OBJECTIVE--To estimate the financial effect of random yearly variations in need for services on fundholding practices with various list sizes. DESIGN--A simulation model was derived using historical data on general practitioner referrals for the 113 surgical procedures covered by the general practitioner fund, combined with data on the hospital prices for those procedures. PATIENTS--Resident population of Central Birmingham Health Authority. MAIN OUTCOME MEASURES--Expected expenditure on the relevant surgical procedures for the whole district and for practices with list sizes of 9000, 12,000, 15,000, 18,000, 21,000, or 24,000 for each of 100 simulated years. RESULTS--By using average hospital prices for the West Midlands region the mean (SD) annual expenditure for the 179,400 residents was 4,832,471 pounds (87,149 pounds); the random variation between the 5th and 95th most expensive years was 5.7% of the mean cost. For a practice with a list size of 9000 the values were 244,891 pounds (18,349 pounds), with a variation of 27.5%. With a list size of 24,000 the values were 652,762 pounds (32,512 pounds), with a variation of 15.3%. CONCLUSIONS--Random variations in need for inpatient services will have a significant financial impact on the practice fund. The problem will be particularly great for smaller practices. Additional measures are required to ensure that the scheme is not undermined and that the potential benefits are secured.     

Medical audit data: counting is not enough.

OBJECTIVE--To assess the meaningfulness of a year''s worth of audit data relating to all the inpatients of one consultant general surgeon and to question the usefulness of certain outcome measures. DESIGN--Analysis of records entered on to audit computer (Dunnfile) and relating to inpatient episodes for one consultant general surgeon over one year. Data obtained were compared with ward records and the patient administration system to check their accuracy. SETTING--The three hospitals and 12 wards in Brighton health district where the surgeon admitted patients. SUBJECTS--859 Records relating to inpatient episodes from 1 January to 31 December 1988. These covered 655 main procedures and 79 secondary procedures performed at the same time. MAIN OUTCOME MEASURES--Procedures were analysed by complexity of operation (BUPA code) and grade of surgeon; complications were counted and rates constructed by surgeon and by BUPA code: returns to theatre were analysed. RESULTS--Simple counts revealed some data, such as the fact that one registrar performed more major operations (32) than the senior registrars (22 and 14), and an analysis of complications showed that he had a lower complication rate (11.4% v 20.0% and 19.4%). But the simple complication rate disclosed nothing about whether the complication was avoidable. Likewise, the number of returns to theatre needed further qualification. Analysis of data collection for February to April 1988 showed a 30% deficit of information on the audit system compared with ward records and prompted a re-examination of everyone''s role in collecting data. After the year''s audit there was still a 17% shortfall compared with the district''s patient administration system, though some of this was accounted for by a backlog of work. CONCLUSIONS--It is difficult to ensure adequate data collection and entails everyone in an unfamiliar discipline. Connecting the audit system to the patient administration system would help. Despite the limitations of crude analyses of workload and complications rates, the audit data helped to measure activity and in the management of the firm. Nevertheless, time and care have to be taken in presenting and interpreting audit data carefully. IMPLICATIONS--Counting is not enough.     

Fair shares in health care? Ethnic and socioeconomic influences on recording of preventive care in selected inner London general practices. Healthy Eastenders Project.

OBJECTIVE--To describe the association of ethnic and socioeconomic status with recording of preventive care information by selected general practitioners. DESIGN--Random selection of people aged 20-64 registered with 43 general practitioners. Ethnic and social characteristics of stratified samples were determined at interview in the subject''s home. Recording of preventive information was ascertained from general practitioners'' medical records. SETTING--Inner London borough of Tower Hamlets. SUBJECTS--505 ut of 739 people confirmed as residents at their home address (190 white, 86 black, 112 Bangladeshi, 105 Chinese or Vietnamese, 12 other). MAIN OUTCOME MEASURES--Socioeconomic characteristics, consultation with general practitioner, and recorded preventive activities for ethnic groups. RESULTS--Minority ethnic groups were considerably more disadvantaged than white people and five times more likely to be overcrowded (31% v 6%), three times less likely to own their own home(11% v 37%), twice as likely to be in social classes IV and V (54% v 28%) and less likely to be employed (34% v 63%). There were no significant differences between white, black, Bangladeshi, and Chinese or Vietnamese subjects in recording smoking, blood pressure, alcohol consumption, weight, and height in the general practitioners'' medical records. White women were more likely to have a record of mammography (46% v 20%; P=0.03) and of cervical smears than women in minority ethnic groups. CONCLUSION--Despite major socioeconomic inequity, equitable recording of preventive activity for the major causes of death for white, black and Bangladeshi populations is possible. Chinese and Vietnamese people had lower levels of recording and consultation. Mammography and, to a lesser extent, cervical cytology are inequitably recorded and require additional support at practice level.     

Narrowing the health gap between a deprived and an endowed community

A 15 month campaign by a primary health care team in Stockton on Tees raised the uptake of preventive care of its patients in a severely deprived area to a level generally exceeding that of a more endowed neighbouring community. This was achieved by opportunistic attention after unrelated consultations, writing twice to each household with a list of its outstanding items necessary for preventive care, using health visitors to encourage attendance, and occasionally undertaking preventive care in patients'' homes. Extra clerical staff were needed to implement the new recording and monitoring procedures introduced.With rigorous monitoring and organisation general practitioners may improve the uptake of preventive health care by their more deprived patients.     

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.     

Responses by general practitioners in Avon to proposals for general practice in the white paper Working for Patients.

OBJECTIVE--To determine the views of Avon''s general practitioners about the general practice proposals within the government''s white paper Working for Patients. DESIGN--Postal questionnaire survey. SETTING--A county in south west England. SUBJECTS--All general practitioner principals (n = 537) under contract with Avon Family Practitioner Committee. MEASUREMENTS AND MAIN RESULTS--492 doctors (92%) responded to the survey. More than three quarters of the respondents were opposed to the government''s proposals on budgets for specific surgical procedures, prescribing, and diagnostic tests; and between 63% and 93% felt negative about advantages that might accrue from the proposals. Over three quarters of general practitioners were in favour of family practitioner committees monitoring work load, prescribing, and referrals. General practitioners in large, potentially budget holding practices held similar views to doctors in smaller practices. CONCLUSIONS--Avon''s general practitioners substantially reject most of the government''s proposals about general practice in the white paper Working for Patients.     

Randomised controlled trial of computer assisted management of hypertension in primary care.

The hypothesis that general practitioners would obtain better outcomes for patients with hypertension using a computer than doctors not using a computer was tested. Sixty family physicians were randomised to two treatment strategies. "Test" physicians completed a data collection form after each visit from a patient with hypertension and mailed the forms to the test centre for processing. Computer feedback on management was mailed to the doctors. This encouraged doctors to apply the "stepped care" protocol, supplied charts of diastolic blood pressure v time, and ranked patients'' diastolic blood pressures by percentile. Letters were mailed to patients to remind them of appointments. "Control" doctors filled out the same data collection forms as test physicians, but neither doctors nor patients received computer feedback. Physicians who used the computer saw more patients per practice than control doctors (test 50 patients, control 40). For all patients the length of follow up was significantly longer in test practices (test 199 days, control 167), and a smaller percentage dropped out of active treatment in test practices (test 37.5%, control 42.1%). For patients with "moderate" hypertension of a baseline diastolic pressure of greater than 104 mm Hg the mean score of the last recorded pressure was below the goal of 90 mm Hg in test practices (88.5 mm Hg), but it failed to reach this goal in control practices (93.3 mm Hg). A greater average reduction of diastolic pressure was achieved in test practices (test 21.7 mm Hg, control 16.7 mm Hg). Though patients with "moderate" hypertension were better controlled in test practices than in control practices, the patients in test practices visited their doctors less often (test 13.3 visits per patient-year, control 17.4 visits). Among patients with newly detected hypertension test practices achieved a greater reduction in diastolic pressure than control practices (test 15.1 mm Hg v control 11.3 mm Hg) and more sustained control of hypertension (test 323 days per patient-year with a diastolic pressure of 90 mm Hg or less v control 259 days).     

Computerisation of primary care in Wales.

OBJECTIVE--To obtain information about the computerisation of general practice in Wales, and to enable more effective planning of educational provision for doctors and other primary health care workers. DESIGN--Postal questionnaire sent to all general practices in Wales. SUBJECTS--553 general practices, of which 401 (73% replied). RESULTS--The level of computerisation varied from 11 (85%) of practices in Powys Family Health Services Authority to 22 (40%) in Mid Glamorgan. Less than half of practices had a computer in only two authorities. The commonest uses of the computer were for patient registration (208 practices), repeat prescribing (180), call and recall of patients (165), and partial clinical records (122). The main suppliers were VAMP (78 practices), AAH Meditel (46), and AMC (23). 102 of 226 practices with a computer had a terminal on each doctor''s desk. Just 33 practices had full patient notes on computer and 51 had modems for electronic communication. CONCLUSION--Mechanisms to encourage greater and more sophisticated use of computers and information technology need to be explored.     

Identifying predictors of high quality care in English general practice: observational study

ObjectivesTo assess variation in the quality of care in general practice and identify factors associated with high quality care.Design Observational study.Setting Stratified random sample of 60 general practices in six areas of England.Results Quality of clinical care varied substantially, and access to care, continuity of care, and interpersonal care varied moderately. Scores for asthma, diabetes, and angina were 67%, 21%, and 17% higher in practices with 10 minute booking intervals for consultations compared with practices with five minute booking intervals. Diabetes care was better in larger practices and in practices where staff reported better team climate. Access to care was better in small practices. Preventive care was worse in practices located in socioeconomically deprived areas. Scores for satisfaction, continuity of care, and access to care were higher in practices where staff reported better team climate.Conclusions Longer consultation times are essential for providing high quality clinical care. Good teamworking is a key part of providing high quality care across a range of areas and may need specific support if quality of care is to be improved. Additional support is needed to provide preventive care to deprived populations. No single type of practice has a monopoly on high quality care: different types of practice may have different strengths.

What is already known on this topic

Quality of care varies in virtually all aspects of medicine that have been studiedMost studies look at quality of care from a single perspective or for a single condition

What this study adds

Quality of care varies for both clinical care and assessments by patients of access and interpersonal carePractices with longer booking intervals provide better management of chronic disease; preventive care is less good in practices in deprived areasNo single type of practice has a monopoly on high quality care—small practices provide better access but poorer diabetes careGood team climate reported by staff is associated with a range of aspects of high quality care     

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.     

Collecting morbidity data in general practice: the Somerset morbidity project.

OBJECTIVE--To collect a valid, complete, continuous, and representative database of morbidity presenting to primary care and to use the data to help commission services on the basis of local need and effectiveness. SETTING--Computerised general practices in Somerset. METHODS--Participating general practices were selected to be representative of the district health authority population for general practice and population characteristics. All conditions presented at face to face consultations were assigned a Read code and episode type and the data were regularly validated. Data were sent by modem from the practices via a third party to the health authority each week. MAIN OUTCOME MEASURES--Proportion of consultations coded and accuracy of coding. RESULTS--11 practices agreed to participate. Validations for completeness during April 1994 to March 1995 revealed that 96.4% of the records were coded; 94% of the 1090 records validated had appropriate episode types and 87% appropriate Read codes. The results have been used to help formulate the health authority''s purchasing plans and have enabled a change in the local contracts for surgery for glue ear. CONCLUSIONS--The project has shown the feasibility of establishing a network of practices recording and reporting the morbidity seen in primary care. Early indications are that the data can be useful in evidence based purchasing.     

What factors influence primary care physicians' charges for their services? An exploratory study using standardized patients

OBJECTIVE: To determine the extent of variation in physicians'' charges for health care encounters with unannounced standardized patients and factors associated with the variation. DESIGN: Cross-sectional study. SETTING: Family practices open to new patients within 1 hour''s drive of Hamilton, Ont. PARTICIPANTS: A stratified random sample of 125 physicians who had responded to an earlier survey regarding preventive care were invited to participate. Of the 125, 44 (35.2%) declined to participate, and an additional 19 (15.2%) initially consented but later withdrew because 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: 28-year-old woman, 52-year-old woman, 48-year-old man and 70-year-old man. OUTCOME MEASURES: Physician characteristics, encounter characteristics and charges made for services. RESULTS: The 62 physicians had 246 encounters with the standardized patients. Charges were made to the health insurance plan for services by 59 physicians for up to 4 encounters (215 encounters in all). Charges varied considerably both within and across patient scenarios. Time spent with the patient was an important factor predicting charges made (p < 0.01), although the effect of time spent on charges varied across scenarios (p < 0.01). Fee-for-service physicians charged more for their services than physicians who usually had alternative billing arrangements (p < 0.01). Female physicians charged more for their services than their male colleagues (p = 0.03). No relation was found between quality of preventive care and charges made (p = 0.15). CONCLUSIONS: Physician-related factors are better able to account for the variability in charges for their services than patient-related factors. Physicians seeing comparable patients may earn much more or less than their colleagues because of differences in the services they provide and the way they apply the fee schedule. Quality-assurance techniques are likely needed to reduce the variability in charges seen and increase value for money spent in health care.     

General practitioners' views about the statutory annual practice report.

OBJECTIVE--To ascertain the views of primary care professionals about the current purpose, uses, potential, and workload implications of the statutory general practice annual report. DESIGN--Postal questionnaire survey. SETTING--General practices in the Northern region. SUBJECTS--All practices in the region that were singlehanded, fundholding, non-fundholding and with more than five partners, and a one in three random sample of all non-fundholding practices (n = 318). RESULTS--263 practices responded (83%). The report took a median of 12 hours to produce (95% confidence interval 11 to 15 hours; interquartile range 7-35). The main perceived purpose of the report was to monitor practice activity (165 respondents; 63% (95% confidence interval 57% to 69%)), but 44 respondents (17%; 13% to 22%) produced it only because it was contractually required. Practices included statutory and non-statutory data in these reports and would have liked comparative practice activity information (155 respondents; 59%) and "good ideas" (165 respondents; 63%) fed back to them. Respondents would have liked the annual report used to improve practice development planning (122 respondents; 46% (40% to 52%)), to facilitate audit (115 respondents; 44% (38% to 50%)), and to influence resource allocation (104 respondents; 40% (34% to 46%)). One hundred and eighteen practices (45%; 39% to 51%) would produce an annual report even if not contractually required. Data collected were perceived to be already available elsewhere. CONCLUSIONS--Primary care professionals have concerns about the current annual report. They would prefer to collect relevant, standardised data which could lead to better audit, planning, and resource allocation.
