Developing a 'consultation quality index' (CQI) for use in general practice.

BACKGROUND: The core values of general practice include holism and patient-centredness. None of the measures of quality of care in general practice presently capture the expression of these values at routine consultations. OBJECTIVES: The aim of the present study was to construct a 'consultation quality index' (CQI) which reflects the core values of general practice, using as proxies 'consultation length' and how well patients 'know the doctor' as process measures and 'patient enablement' as an outcome measure. METHODS: The CQI was constructed from data collected from 23 799 adult English-speaking patients consulting 221 doctors in four demographically contrasting areas of the UK during 2 weeks of March/April 1998. A total of 171 doctors who entered 50 qualifying consultations were allocated scores for the three component variables, and a total CQI was calculated. RESULTS: CQI scores were in the range 4-18. Validity was examined by looking at high and low scorers in greater detail and by searching for correlates with case mix, patient age and gender, and the deprivation scores of the practices concerned. Particular attention was paid to how registrars and doctors new to their practices scored. The scores of different doctors in the same practice were also noted. The results had strong face validity and were independent of case mix and deprivation. Reliability was gauged by examining similar work from a previous study which had collected information on consultation length and enablement over three time periods. High CQI scores were associated with smaller overall practice list sizes. CONCLUSIONS: We have outlined possible uses for the CQI as part of the packages assessing quality of care by doctors and practices. The measure may also have a part to play in recognizing poorly performing doctors. We suggest how CQI scores could contribute to an incentive scheme to reward good consulting practice. Further work is in hand to compare doctors' CQI scores with scores based on performance indicators constructed from routine NHS data on prescribing and preventive medicine.

Quality at general practice consultations: cross sectional survey.

OBJECTIVES: To measure quality of care at general practice consultations in diverse geographical areas, and to determine the principal correlates associated with enablement as an outcome measure. DESIGN: Cross sectional multipractice questionnaire based study. SETTING: Random sample of practices in four participating regions: Lothian, Coventry, Oxfordshire, and west London. PARTICIPANTS: 25 994 adults attending 53 practices over two weeks in March and April 1998. MAIN OUTCOME MEASURES: Patient enablement, duration of consultation, how well patients know their doctor, and the size of the practice list. RESULTS: A hierarchy of needs or reasons for consultation was created. Similar overall enablement scores were achieved for most casemix presentations (mean 3.1, 95% confidence interval 3.1 to 3.1). Mean duration of consultation for all patients was 8.0 minutes (8.0 to 8.1); however, duration of consultation increased for patients with psychological problems or where psychological and social problems coexisted (mean 9.1, 9.0 to 9.2). The 2195 patients who spoke languages other than English at home were analysed separately as they had generally higher enablement scores (mean 4.5, 4.3 to 4.7) than those patients who spoke English only despite having shorter consultations (mean 7.1 (6. 9 to 7.3) minutes. At individual consultations, enablement score was most closely correlated with duration of consultation and knowing the doctor well. Individual doctors had a wide range of mean enablement scores (1.1-5.3) and mean durations of consultation (3. 8-14.4 minutes). Doctors' ability to enable was linked to the duration of their consultation and the percentage of their patients who knew them well and was inversely related to the size of their practice. At practice level, mean enablement scores ranged from 2.3 to 4.4, and duration of consultation ranged from 4.9 to 12.2 minutes. Correlations between ranks at practice level were not significant. CONCLUSIONS: It may be time to reward doctors who have longer consultations, provide greater continuity of care, and both enable more patients and enable patients more.

A comparison of a Patient Enablement Instrument (PEI) against two established satisfaction scales as an outcome measure of primary care consultations.

OBJECTIVES: We aimed to compare a new primary care outcome measure-the Patient Enablement Instrument (PEI)-against two established satisfaction measures [the Medical Interview Satisfaction Scale (MISS) and the Consultation Satisfaction Questionnaire (CSQ)]. Specifically, we sought (i) to test whether enablement and satisfaction are related or separate concepts; and (ii) to assess whether the internal consistency of the PEI might be enhanced by the inclusion of items from the satisfaction instruments. METHODS: Questionnaire forms containing the three instruments in a variety of combinations were distributed to a total of 818 patients attending for routine surgery consultations in three urban general practices of varying socio-economic mix. The main outcome measures were: scores on the PEI; scores on the CSQ, the MISS and their individual components; rank correlations between scores on the PEI and scores on the CSQ, the MISS and their component subscales; and Cronbach's alpha coefficient for the PEI. RESULTS: Overall mean scores, expressed as percentages of maximum scores attainable, were 44.1% for the PEI, 76.9% for the CSQ and 77.6% for the MISS. Rank correlations between PEI scores and scores for the complete CSQ and MISS instruments were 0.48 (P < 0.01) and 0.47 (P < 0.01), respectively. Correlations of PEI scores with individual component scores on the CSQ were generally lower and ranged from 0.14 to 0.53; correlations of PEI scored with MISS component scores were also generally lower and ranged from 0.21 to 0.53. Internal consistency of the PEI items (assessed by Cronbach's alpha coefficient) was lowered when items from the CSQ or MISS were added. CONCLUSIONS: The study shows that 'enablement' is a primary care outcome measure which is related to but is different from general satisfaction.

Measuring quality in general practice. Pilot study of a needs, process and outcome measure.

1. As part of the Scottish Shadow Fundholding Evaluation (1990-92), quality of care was assessed in 6 practices with 49 general practitioners using a pre-consultation health needs questionnaire, consultation length as a process measure (previously shown to be a proxy measure for quality) and a post-consultation satisfaction/outcome measure which contained a subset of six questions assessing whether patients felt enabled by their consultation. This report describes secondary analysis of the available dataset undertaken to explore whether the approach used to evaluate quality of care for patients with specific clinical problems could be extended to the generality of general practice consultations. 2. Chapters 1 and 2 of the report describe earlier work developing both the concepts and instruments used in the Shadow Evaluation, and general findings already reported. The reliability and the construct validity of the measure of enablement are examined and found to be satisfactory. 3. Strong correlations between more time at consultations and more enablement for more patients are found at population level for patients with psychological problems, with social problems and with physical problems. More complex problems require more time to achieve equal benefit. 4. Mean consultation length and mean enablement score correlate well with each other and can be used as summary statistics of quality. Where trends require explanation or exploration, other measures of the use of time and the level of benefit gained are more helpful; both sets of analyses can be derived from the same datasets (Chapter 3). 5. Analyses at practice level show that practices which spend more time at consultations enable patients more whatever the nature of problems presented. The rank orders of time spent at consultation and of enablement are highly correlated (Chapter 4). 6. Analyses at doctor level show that doctors who spend more time at consultations enable patients more and that those who spend less time enable patients less. The numbers of patients available for study were not sufficient to explore this association within subgroups of clinical presentations. As in previous studies, we found that doctors who take longer time are likely to be more patient centred, and those who take less time are likely to be less patient centred. Case-mix varies between doctors, but seems to be independent of whether a doctor is more or less patient centred (Chapter 5). 7. The methods developed in this study give useful insights into the definition and delivery of quality of care in general practice (Chapter 6). The measures now need to be tested in different clinical, cultural and organizational settings and results compared with those found using routinely available NHS data on prescribing and achievement of other clinical and management targets (Chapter 7).

Auditing out-of-hours primary medical care.

As a preliminary to evaluating the introduction of a primary care emergency centre in Midlothian, information was recorded about 2,236 out-of-hours contacts made with eight general practices in the ten weeks before the centre opened. The overall rate of calls was estimated at 265 cells per 1,000 patients per year, with 63% of calls resulting in a home visit, 8% in the patient being seen at the surgery and 29% in telephone advice only; 18% of the out-of-hours calls generated a night visit fee. Eighty-five per cent of patients who requested a home visit were seen by a doctor and 15% of patients contacting their general practitioner out of hours were referred to hospital, either for admission or for treatment in an accident and emergency department. Doctors classified 61% of the calls as necessary, 29% as unnecessary and were unsure about the need for 9% of calls.

Care of patients with selected health problems in fundholding practices in Scotland in 1990 and 1992: needs, process and outcome.

BACKGROUND: At the time of the introduction of fundholding, a number of potential benefits and concerns about fundholding were debated. AIM: A study was undertaken to compare process and outcome of care in patients with different levels of physical, social and psychological need in 1990 and 1992 in six fundholding groups in Scotland. METHOD: Patients aged 16 years and over consulting with a range of marker conditions in 1990 and 1992 completed a pre-consultation health status questionnaire asking about physical, social and psychological problems, and a postconsultation satisfaction/enablement questionnaire asking about their ability to cope, and understand their illness. Main outcome measures were consultation length and satisfaction/enablement score. RESULTS: Of patients attending in the study period, 39% consulted for one or more marker condition. The proportion of patients reporting social problems rose between 1990 and 1992 for 11 out of 12 conditions. Overall, consultation lengths remained constant. Patients wanting to discuss social problems had significantly longer consultations than those reporting no social problems or problems they did not wish to discuss. The proportion of patients expressing enablement dropped for eight conditions and rose for four between 1990 and 1992. The decrease in the proportion expressing enablement remained after controlling for the rise in the percentage reporting social problems. Patients who had social problems they did not wish to discuss but a general health questionnaire score of five or more were the group reporting lowest enablement. Significantly more patients with pain, skin problems and digestive problems reported social problems and significantly fewer of them reported enablement in 1992 compared with 1990. Patients with diabetes, angina, chronic bronchitis and problems seeing fared relatively well over the study period. Some patients with psychosocial problems fared poorly (they had relatively short consultations and were unlikely to express an ability to cope/understand their illness). CONCLUSION: The issue of whether benefits to some patient groups from recent health service changes may be matched by disadvantage to other groups, for example those with clinical problems with no financial incentive to provide pro-active care or with psychosocial difficulties, is discussed.

Evaluating care of patients reporting pain in fundholding practices.

OBJECTIVE: To compare quality of care between 1990 and 1992 in patients with self diagnosed joint pain. DESIGN: Questionnaire and record based study. SUBJECTS: Patients identified at consecutive consultations during two weeks in 1990, 1991, and 1992. SETTING: Six practice groups in pilot fundholding scheme in Scotland. MAIN OUTCOME MEASURES: Length of consultation; numbers referred or investigated or prescribed drugs; responses to questions about enablement and satisfaction. RESULTS: About 15% of patients consulted with joint pain each year. 25% (316) of them had social problems in 1990 and 37% (370) in 1992; about a fifth wanted to discuss their social problems. Social problems were associated with a raised general health questionnaire score. The mean length of consultation for patients with pain was 7.6 min in 1990 and 7.7 min in 1992. Patients wishing to discuss social problems received longer consultations (8.5 min 1990; 10.4 min 1992); but other patients with social problems received shorter consultations (7.4 min; 7.2 min). The level of prescribing was stable but the proportion of patients having investigations or attending hospital fell significantly from 1990 to 1992 (31% to 24%; 31% to 13% respectively). Fewer patients responded "much better" to six questions about enablement in 1992 than in 1990. Enablement was better after longer than shorter consultations for patients with social problems. CONCLUSIONS: Quality of care for patients with pain has been broadly maintained in terms of consultation times. The effects of lower rates of investigation and referral need to be investigated further.

The chief scientist reports ... Evaluation of the Scottish shadow fund-holding project: first results.

This paper reports preliminary findings from the action research evaluation of the Scottish shadow fund-holding project. Fifty doctors looking after 84,000 patients in six groups negotiated and managed a paper fund for six months, and then a real fund for six months. First analyses of quantitative data suggest that the numbers of prescriptions written, investigations done and referrals made remained stable over the period of study. The length of time spent at consultations varied apparently independently of holding a fund. Patient satisfaction with actions taken by doctors and their feelings of benefit from consultations were high throughout the study, but a consistent and significant shift from very satisfied to satisfied categories was noted in all practices for most variables surveyed during the course of 1990-91. Analyses to explain this are continuing. Qualitative study identified benefits in terms of a greater understanding of the costs of activities, and new working patterns between hospital, general practice and administrative staff have led to progressive work in contracting for quality of patient care. At the same time, the lack of sophistication of fund setting needs to be addressed; equity issues will become relevant as fund-holding reaches a larger proportion of practices. The pressures on those taking leading roles in administration are high, and this is confirmed by parallel quantitative work. Further information is becoming available on both prescribing and the care of selected 'marker' conditions, and these will be the subject of further reports.

Attaching prices to decision making in general practice.

This paper is an attempt to evaluate the cost implications of decisions made by general practitioners during consultations. Prices were attached to the cost generating decisions of 85 general practitioners in South East Scotland who participated in a 12-month study of their workload. When the price attached to each referral decision was one out-patient attendance, 56 of the 85 general practitioners' costs per consultation were within 15% of the average cost, and 76 were within 25% of the average. However, when the price attached to referral activity was adjusted upwards (to allow for the inclusion of further hospital care), variations between doctors became more pronounced and the decision to refer replaced prescribing as the most important element of variable cost. No important relationships were discovered which linked cost generating activities with characteristics of the doctor or the practice. Implications for fund-holding are discussed.

Attitudes to medical care, the organization of work, and stress among general practitioners.

Eighty five volunteer general practitioners in Lothian region recorded clinical and contextual information on 21,000 consultations during 1987-88. During their recording sessions they reported their perceived levels of stress using a previously validated scale. Subsequently, 80 of the doctors completed a previously validated multi-dimensional scale about their attitudes to patient care. Three attitude subscales (psychological orientation, appropriateness of consultations and responsibility for decisions) correlated with processes of care previously identified as indicators of good care. The 20 doctors who scored most highly on these patient-centred scales recorded self-perceived stress in 27% of their consultations compared with 11% of the consultations of the 33 doctors who scored lowest on these scales. Among the 20 most patient-centred doctors those booking patients at eight patients per hour or more reported stress at twice as many consultations as those with a longer booking interval; doctors whose preferred working styles conflicted with their booking patterns reported stress in up to 62% of consultations. Doctors with a higher patient-centred orientation find their work more stressful. Longer booking intervals remove much of that stress, particularly when doctors' preferred style of consulting requires them to spend more time at individual consultations. Previously described work stressors offer a theoretical explanation for a problem which is important for both doctors and patients.

The chief scientist reports ... The Scottish general practice shadow fund-holding project--outline of an evaluation.

After the agreement in January 1989 between the Minister of Health at the Scottish Office, Mr Michael Forsyth, and six groups of General Practitioners (GPs) in the Grampian and Tayside Regions of Scotland to embark on a 'shadow fund-holding' project, the Government agreed to promote an independent evaluation of the scheme. As a result, the Department of General Practice at Edinburgh University was invited to present plans to evaluate the working of and results of the scheme. Consultations with the Minister and Health Department officials, the general practices concerned, and staff of the two Health Boards involved took place during the first three months of 1990, and an outline protocol for the evaluation was approved and funded through the Chief Scientist Organisation for a three-year period from April 1990. It was agreed by all involved that piecemeal publications of results during the period of the research would be inappropriate, but with other attempts to evaluate fund-holding now being reported elsewhere in the UK, it has been agreed that an outline of issues being explored and the methods being used would be in the general interest. This paper first outlines the principal areas in which the evaluation is being focused, then describes the general methods being used, and finally comments on some of the problems encountered with the evaluation. The project should be seen as a descriptive beginning to what may well be a period of around a decade needed to appreciate the full implications of any major change in the organisation of health service provision.

Factors influencing waiting times and consultation times in general practice.

Using data collected from 85 general practitioners in Lothian, large variations were found in the time patients wait for and spend with their doctor. This study, which sets consultations into their administrative framework, examines factors which cause this variation. Consultation time was found to be affected by the total number of patients attending a particular surgery, while waiting time was found to be affected by an individual patient's place within that surgery queue. Taking these two results together suggests that patients seen at the end of large surgeries are likely to get a different service from their doctor than they would have done earlier in the session, or when attending a less busy surgery. Possible strategies are discussed for reducing average waiting times, thereby decreasing the relative cost of consultation to patients.

Long to short consultation ratio: a proxy measure of quality of care for general practice.

Eighty five general practitioners in the Lothian region recorded information on all surgery consultations on one day in every 15 for a year. On the basis of their mean consultation times with patients the working styles of the general practitioners were described as 'faster' (n = 24), 'intermediate' (n = 40) or 'slower' (n = 21). The 21,707 consultations which they carried out over this period were defined as 'short' (five minutes or less), 'medium' (six to nine minutes) or 'long' (10 minutes or more). Independent of doctor style, 'long' consultations as against 'short' consultations were associated with the doctor: (1) dealing with more of the psychosocial problems which had been recognized and were relevant to the patient's care; (2) dealing with more of the long term health problems which had been recognized as relevant; and (3) carrying out more health promotion in the consultation. Patients also reported greater satisfaction with longer consultations. The ratio of long:short consultations was found to be 0.28:1 for 'faster' doctors as against 2.3:1 for 'slower' doctors. When doctors in either group had more heavily booked surgeries or were running late, the long:short consultation ratio fell, in some cases by over 50%. This paper suggests that the ratio of long to short consultation length for a general practitioner might become the basis of a simply proxy measure of quality of care; and that its use might help monitor the effect of recent and proposed changes in the way in which general practice care is delivered.

Mathematical modeling of phosphorus losses from land application of hog and cattle manure.

Mathematical models may provide a means to estimate phosphorus (P) losses from land application of manure. Phosphorus losses typically occur during brief episodes of runoff and erosion. Models must be able to simulate P losses during these episodes by representing the basic chemical, physical, and biological processes by which these losses occur. The mathematical model ecosys combines dynamic distributed flow of solutes and nonsolutes through runoff and erosion with convective-dispersive transport of solutes, and both biologically and thermodynamically driven transformations between solutes and nonsolutes. This model was tested against P lost in runoff, erosion, and leachate measured during 90 min of controlled rainfall at 65 mm h(-1) on soils from six sites at which different rates of manure had been applied over the previous 3 to 6 yr. Transport and transformation kinetics in the model enabled it to simulate changes of dissolved inorganic phosphorus (DIP) in runoff from >1.0 to <0.05 mg L(-1) and changes of total phosphorus (TP) in sediment from 15 to 3 mg L(-1) measured during controlled rainfall on soils with diverse P contents. Results from 60-yr model runs using these kinetics with different application rates of cattle manure indicated that (i) a positive interaction exists between annual rainfall and application rate on P losses and (ii) rates greater than 30 Mg ha(-1) yr(-1) would cause TP concentrations in water leaving the site to rise above acceptable limits. The interaction between rainfall and rate suggests that P losses from manure application at any site should be assessed under the upper range of likely rainfall intensities.
