Interventions for improving patients' trust in doctors and groups of doctors.

BACKGROUND: Trust is a fundamental component of the patient-doctor relationship and is associated with increased satisfaction, adherence to treatment, and continuity of care. It is not clear if there are interventions known to be effective in enhancing patient trust in doctors. OBJECTIVES: To assess the effects of interventions intended to improve a patient's trust in the doctor or a group of doctors. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1 2003), MEDLINE(1966 to week 4 2003), EMBASE (1985 to July 2003), Health Star (1975 to July 2004), PsycINFO (1967 to July 2004), CINAHL (1982 to June 2003), LILACS (1982 to April 2003), African Trials Register (1948 to April 2003), African Health Anthology (1924 to April 2003), Dissertation Abstracts International (1861 to April 2003) and the bibliographies of studies assessed for inclusion. We also searched the bibliographies of studies assessed for inclusion, and contacted researchers active in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs), controlled clinical trials, controlled before and after studies, and interrupted time series studies of interventions (informative, educational, behavioural, organisational) directed at doctors or patients (or carers) where trust was assessed as a primary or secondary outcome. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. MAIN RESULTS: Three RCTs, all published in English and set in North American primary care, and involving 1916 participants, were included. There was considerable heterogeneity in terms of aims, format and content of the interventions. One trial of a training intervention for family doctors to improve communication behaviours (20 doctors assessed by 414 patients) showed no effect on trust. The other two interventions were patient focussed. One explored the impact on trust of disclosing physician incentives to patients (n= 918) in a Health Maintenance Organisation (HMO) and showed no diminution in trust. Another investigated the effect of induction visits on new HMO members' (n=564) trust in their HMO doctors. Trust in doctors rose compared with control following the visit for one type of induction visit, the group visit (Trust out of 10 (standard deviation (SD)) was 8.8 (1.5) and 7.1 (2.2), difference 1.7, (95% confidence interval 1.22 to 2.18)). However there were many drop-outs and analysis was not on intention to treat. AUTHORS' CONCLUSIONS: Overall there remains insufficient evidence to conclude that any intervention may increase or decrease trust in doctors. Further trials are required to explore the impact of policy changes, guidelines and specific doctors' training on patients' trust.

Understanding reasons for asthma outpatient (non)-attendance and exploring the role of telephone and e-consulting in facilitating access to care: exploratory qualitative study.

OBJECTIVE: To understand factors influencing patients' decisions to attend for outpatient follow up consultations for asthma and to explore patients' attitudes to telephone and email consultations in facilitating access to asthma care. DESIGN: Exploratory qualitative study using in depth interviews. SETTING: Hospital outpatient clinic in West London. PARTICIPANTS: Nineteen patients with moderate to severe asthma (12 "attenders" and 7 "non-attenders"). RESULTS: Patients' main reasons for attending were the wish to improve control over asthma symptoms and a concern not to jeopardise the valued relationship with their doctor. Memory lapses, poor health, and disillusionment with the structure of outpatient care were important factors implicated in non-attendance. The patients were generally sceptical about the suggestion that greater opportunity for telephone consulting might improve access to care. They expressed concerns about the difficulties in effectively communicating through non-face to face media and were worried that clinicians would not be in a position to perform an adequate physical examination over the telephone. Email and text messaging were viewed as potentially useful for sending appointment reminders and sharing clinical information but were not considered to be acceptable alternatives to the face to face clinic encounter. CONCLUSIONS: Memory lapses, impaired mobility due to poor health, and frustration with outpatient clinic organisation resulting in long waiting times and discontinuity of care are factors that deter patients from attending for hospital asthma assessments. The idea of telephone review assessments was viewed with scepticism by most study subjects. Particular attention should be given to explaining to patients the benefits of telephone consultations, and to seeking their views as to whether they would like to try them out before replacing face to face consultations with them. Email and text messaging may have a role in issuing reminders about imminent appointments.

Selective recording in blood pressure readings may increase subsequent mortality.

BACKGROUND: Rounding blood pressure (BP) to the nearest 10 mmHg (terminal digit preference) and selecting for particular values near treatment cut-offs (number preference) have both been previously described. Both reduce measurement accuracy, and may have consequences for treatment and survival. AIM: To check for number preference in screening for hypertension, and whether this influenced subsequent mortality. DESIGN: Prospective case-control screening study. METHODS: In the General Practice Hypertensive Study Group (GPHSG), prospective case control study patients (n=23 574) were screened on one occasion for high phase-IV diastolic BP (DBP4) (> or =90 mmHg). Identified cases were matched with normotensive controls for age, sex, date of screen and ethnic group, and were registered for mortality follow-up (n=6310). Patients with a high DBP4 had two further readings, and were treated if it remained elevated. RESULTS: For DBP4 terminal digit, '0' was over-represented (28.2% vs. 20%), and the number '88' was over-represented in both men and women. There was an excess adjusted death rate for females with DBP4 88-89 mmHg vs. 90-99 mmHg for both cardiovascular (RR 2.56, 95%CI 1.43-4.56, p=0.0015) and all-cause (1.56, 95%CI 1.06-2.29, p=0.023) mortality. For males, the corresponding rates were non-significantly reduced: cardiovascular RR 0.69, 95%CI 0.42-1.14, p=0.15; all-cause RR 0.93, 95%CI 0.68-1.27, p=0.64. DISCUSSION: The quality of BP measurements should be monitored both in research studies and in clinical practice as part of clinical governance procedures.

An exploration of the value of the personal doctor-patient relationship in general practice.

BACKGROUND: Within the context of general practice, continuity of care creates an opportunity for a personal doctor-patient relationship to develop which has been associated with significant benefits for patients and general practitioners (GPs). Continuity of care is, however, threatened by trends in the organisational development of primary health care in the United Kingdom and its intrinsic role within general practice is currently the subject of debate. AIMS: To determine how many patients report having a personal doctor and when this is most valued, to compare the value of a personal doctor-patient relationship with that of convenience, and to relate these findings to a range of patient, GP, and practice variables. DESIGN OF STUDY: Cross sectional postal questionnaire study. SETTING: Nine hundred and ninety-six randomly selected adult patients from a stratified random sample of 18 practices and 284 GP principals in Oxfordshire. METHOD: Qualitative interviews with patients and GPs were conducted and used to derive a parallel patient and GP questionnaire. Each patient (100 from each practice) was invited to complete a questionnaire to evaluate their experience and views concerning personal care. All GP principals currently practising in Oxfordshire were sent a similar questionnaire, which also included demographic variables. RESULTS: Overall, 75% of patients reported having at least one personal GP. The number of patients reporting a personal GP in each practice varied from 53% to 92%. Having a personal doctor-patient relationship was highly valued by patients and GPs, in particular for more serious, psychological and family issues when 77-88% of patients and 80-98% of GPs valued a personal relationship more than a convenient appointment. For minor illness it had much less value. CONCLUSIONS: Patients and GPs particularly value a personal doctor-patient relationship for more serious or for psychological problems. Whether a patient has a personal GP is associated with their perception of its importance and with factors which create an opportunity for a relationship to evolve.

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.

Better by half: hypertension in the elderly and the 'rule of halves': a primary care audit of the clinical computer record as a springboard to improving care.

BACKGROUND: Despite recent studies highlighting the benefits of treating elderly hypertensives, researchers have shown that the taking on board of these findings has been disappointing in primary care, where the 'rule of halves' still applies. Clinical computers could help performance in this area, yet national and local research suggests that they are under-used. OBJECTIVE: Our aim is to develop a pragmatic intervention which aims to: improve patient care by translating research findings into practice, increase meaningful computer use, establish 'paperless' annual audits and improve 'networking' between practices. METHOD: Following a baseline audit to ascertain accuracy, the computer records of participating practices were tested against the 'rule of halves' for hypertension. Results were presented to each practice (individual practice and aggregate data for all practices). Management guidelines, standardization of computer recording, achievable targets and review dates were agreed. The study was conducted in West London practices using the EMIS computer system in 1996/1997. RESULTS: An 81% (22/27) practice response rate was achieved. Baseline audit was completed for 22 practices. Fifteen practices appear to be using their computer regularly (two-thirds). Using strict definitions, 'the rule of halves' still applies. Using looser definitions, three-quarters of hypertensives are known, two-thirds are treated and just under two-thirds are controlled. This project identified wide inter- and intra-practice variation in: use of the computer, patient follow-up, attainment of target BP, rounding BP readings to target levels and prescribing patterns. CONCLUSION: This focused training intervention has introduced practices to evidence-based proactive care and highlighted an important application for clinical computers. A local network of practices has been established for future projects. For elderly patients registered with a GP, the rule of halves has been improved upon, provided that a figure of 160/90 is taken as an adequate control. Attainment of target BP in treated hypertensives was similar to that reported from large trials. There is enormous scope for improving identification and follow-up of hypertensives using clinical computers and systematic models of care. The wide inter-practice variation in hypertension management requires further study.

Primary care units in A&E departments in North Thames in the 1990s: initial experience and future implications.

BACKGROUND: In 1992, the Tomlinson Report recommended a shift from secondary to primary care, including specific primary care provision in accident and emergency (A&E) departments. Availability of short-term so-called Tomlinson moneys allowed a number of experimental services. A study of the experience of A&E-based staff is reported to assist general practitioners (GPs) and purchasers and identify areas for further research. AIMS: To find the number and scope of primary care facilities in A&E services in North Thames; to find factors encouraging or inhibiting the setting-up of a successful service; to examine the views of a range of A&E staff including GPs, consultants, and nurses; and to suggest directions for more specific research. METHOD: A postal questionnaire was sent to all North Thames A&E departments, and an interview study of staff in one unit was arranged, leading to a questionnaire study of all GPs employed in North Thames primary care services in A&E. This was followed by interviews of staff members in five contrasting primary care units in A&E. RESULTS: By mid-1995, at least 16 of the 33 North Thames A&E departments ran a primary care service. Seven mainly employed GPs, the others employed nurse practitioners (NPs). Problems for GPs included unclear role definition and their non-availability at times of highest patient demand. GPs' reasons for working in A&E sometimes differed from the aims of primary care in an A&E service. Staff interviews revealed differing views about their role and about use of triage protocols. Ethnicity data were being collected, but not yet being used, to improve service to patients. CONCLUSIONS: A number of benefits follow the introduction of primary care practitioners into A&E. Different models have evolved, with a variety of GP and NP staffing arrangements according to local ideas and priorities. There is some confusion over whether these services aim to improve A&E-based care or to divert it to general practice. Cost information is inadequate so far, though the use of GPs has shown the possibility of economy. Appropriate location of services requires clearer identification of costs. This may be possible for the proposed primary care groups.

Preliminary evidence of an association between sensorimotor gating and distractibility in psychosis.

Impaired sensory gating and increased distractibility are key information-processing deficits in schizophrenia. This study evaluated the hypothesis that distractibility is related to reduced sensory gating. Performance on vigilance and distractibility tasks was compared to prepulse inhibition (PPI) of the acoustic startle reflex in 28 stable chronic psychotic patients. PPI significantly correlated with distractibility task score on a continuous performance test and lateralized attention on the Posner test. These results suggest that performance on tests of distractibility and lateralized attention are related to a measure of sensory gating.

Subanesthetic effects of the noncompetitive NMDA antagonist, ketamine, in humans. Psychotomimetic, perceptual, cognitive, and neuroendocrine responses.

BACKGROUND: To characterize further behavioral, cognitive, neuroendocrine, and physiological effects of subanesthetic doses of ketamine hydrochloride in healthy human subjects. Ketamine, a phencyclidine hydrochloride derivative, is a dissociative anesthetic and a noncompetitive antagonist of the N-methyl-D-aspartate subtype of excitatory amino acid receptor. METHODS: Nineteen healthy subjects recruited by advertisements from the community participated in this randomized, double-blind, placebo-controlled study. Subjects completed three test days involving the 40-minute intravenous administration of placebo, ketamine hydrochloride (0.1 mg/kg), or ketamine hydrochloride (0.5 mg/kg). Behaviors associated with the positive and negative symptoms of schizophrenia were assessed by using the Brief Psychiatric Rating Scale. Changes in perception and behaviors associated with dissociative states were assessed by the Perceptual Aberration Subscale of the Wisconsin Psychosis Proneness Scale and the Clinician-Administered Dissociative States Scale. Cognitive function was assessed by using the (1) Mini-Mental State Examination; (2) tests sensitive to frontal cortical dysfunction, including a continuous performance vigilance task, a verbal fluency task, and the Wisconsin Card Sorting Test; and (3) tests of immediate and delayed recall. Plasma levels of cortisol, prolactin, homovanillic acid, and 3-methoxy-4-hydroxyphenethyleneglycol were measured. RESULTS: Ketamine (1) produced behaviors similar to the positive and negative symptoms of schizophrenia; (2) elicited alterations in perception; (3) impaired performance on tests of vigilance, verbal fluency, and the Wisconsin Card Sorting Test; (4) evoked symptoms similar to dissociative states; and (5) preferentially disrupted delayed word recall, sparing immediate recall and postdistraction recall. Ketamine had no significant effect on the Mini-Mental State Examination at the doses studied. Ketamine also had no effect on plasma 3-methoxy-4-hydroxyphenethyleneglycol levels, although it blunted a test day decline in plasma homovanillic acid levels at the higher dose. It also dose dependently increased plasma cortisol and prolactin levels. Ketamine produced small dose-dependent increases in blood pressure. CONCLUSIONS: These data indicate that N-methyl-D-aspartate antagonists produce a broad range of symptoms, behaviors, and cognitive deficits that resemble aspects of endogenous psychoses, particularly schizophrenia and dissociative states.

Personal continuity and the care of patients with epilepsy in general practice.

BACKGROUND: So far no study has shown that patients with a chronic illness benefit from seeing the same doctor in general practice although many believe this to be so. AIM: Epilepsy was chosen as an example to test the hypothesis that if patients see the same doctor more often in general practice they are more likely to discuss personally important aspects of their illness. METHODS: In this cross-sectional survey 99 patients aged 15-84 years with active epilepsy were interviewed at home and then their records were reviewed. The patients came from four large Southampton group practices, one with a strict personal list system and three with combined lists. Outcome measures included reported discussion of feelings about stopping medication, stigma and concealment and the patient's relationship with practice doctors. Continuity was assessed from the records. RESULTS: Discussion of epilepsy was not significantly associated with continuity of doctor but was significantly associated with ease of talking to one or more doctors. CONCLUSION: Encouraging patients with epilepsy to see the same doctor may be less important than improving doctors' communication skills and paying specific attention to the psychosocial aspects of epilepsy as well as to seizure control. It is recommended that a simple checklist including these items is used when a patient's care is reviewed.

Is personal continuity of care compatible with free choice of doctor? Patients' views on seeing the same doctor.

While much has been written about the benefits of personal continuity of care there has been little research about the views of patients. In this cross sectional study 111 patients from three group practices (one of which ran a personal list system) were interviewed at home within a week of consulting a general practitioner. Patients were selected randomly from a systematic series of consulting sessions and a semi-structured interview was administered. Patients receiving more personal continuity of care were likely to be older, to have booked their most recent appointment further in advance, to desire personal continuity of care, to have an external health locus of control and to have a lower extroversion score. In the practice with a personal list, patients had a high level of continuity of care, were satisfied and showed little interest in having a choice of doctor. In the combined list practices patients valued their choice of doctor but often could not exercise it enough and they were more critical. They made more suggestions for change than those in the practice with a personal list system, mostly about receptionists and appointments. It is concluded that most patients like to see the same doctor, but they may not be willing to wait two days for this if there is a quicker option. It may be difficult to deliver both personal continuity of care and choice in group practice.

General practice in the undergraduate curriculum: 20 interviews with Southampton final-year students.

The Primary Medical Care Group at the University of Southampton contributes to the medical curriculum in the first, third and final years. A visiting lecturer from Sweden took the opportunity to interview a sample of 20 final-year students using a qualitative approach. Questioning centered on the impact of the primary care course both in relationship to medicine as a whole and to general practice. It was found that primary medical care was often not seen as a central or integral part of the curriculum but many students acknowledged its important contribution to seeing the patient as a whole and in integrating the various other parts of the curriculum, with significant opportunity for role modelling and informing career choice. A hidden curriculum emerged of attitudes which provided a conflict for some students. Improvements should include clearer dovetailing of primary medical care with other curricular components, limitation of aims with more specific and rigorous assessment and a wide strategy of staff development not confined to those directly involved in general practice attachments.

How much personal care in four group practices?

OBJECTIVE: To establish the degree of continuity of care in general practice. DESIGN: Retrospective study of the records of all eligible patients attending the surgery at randomly selected sessions. SETTING: Four large group practices in the Southampton Health District, one of which operated a strict system of personal lists. PATIENTS: 776 Patients who had been registered for at least two years and had consulted at least 12 times over six years or less. MAIN OUTCOME MEASURES: Continuity score for each patient calculated from the number of consultations (out of the past 12) with his or her usual doctor. Number of the times the patients had consulted the doctor with whom they were registered. RESULTS: In the practice with personal lists a mean of 10 of the 12 consultations had been with the same doctor (83% of consultations), but in the three practices with combined lists the means were 5.9 (49%), 6.2 (52%), and 6.9 (58%). Continuity was associated with increased age and with the recording of a major problem. In the practices with combined lists 63 of 72 children consulted at least five different doctors. Only 140 of 489 patients currently in the practice who were identified as being registered with a doctor had most usually consulted that doctor in the practices with combined lists. CONCLUSIONS: Personal continuity of care may be fairly low in group practice, especially for younger and healthier patients registered at practices with combined lists. These findings support the Department of Health's recent decision to make "target payments" (for cervical smears and childhood immunisations) to groups rather than to individual principals but pose a question for the future of individual clinical responsibility.

Receptionists, appointment systems and continuity of care.

The influence of receptionists on continuity of care in four group practices was examined. Twenty two receptionists were observed making 543 appointments and afterwards were interviewed about their personal priority for continuity of care. One of the practices ran a personal list system. It was found that the personal list practice attracted more requests for a specific doctor and time which were then more difficult to satisfy. Most receptionists thought it was important that patients should see the same doctor but their influence seemed to be small compared with that of the doctor as expressed in practice policies. Marked variation in demand for individual doctors was seen in two of the practices without a personal list system.
