Schizophrenia is a long-term condition for which most people receive medication and psychosocial interventions over many years. National guidelines emphasise the importance of long-term supportive therapeutic relationships with staff to ensure that patients receive the care that they need. 1 In several countries, key worker, case-manager and care-coordinator roles have been developed to try to ensure that people with severe mental illness receive consistent and coordinated care.Reference Horvitz-Lennon, Kilbourne and Pincus 2 , Reference Tansella, Thornicroft and Lempp 3 Although mental health services have focused on making sure that people with severe mental illness have long-term contact with mental health teams, service users may be more likely to value long-term contact with the same person.Reference Crawford, de Jonge, Freeman and Weaver 4 It is therefore concerning that people with schizophrenia report that changes in clinical staff are common and can disrupt the care they receive.Reference Jones, Ahmed, Catty, McLaren, Rose and Wykes 5 Despite the importance of this issue, there is limited information about how often people with schizophrenia have changes in clinical staff who deliver their care. Most studies have been limited to small numbers of services and have had insufficient power to detect clinically important differences in patient outcomes.Reference Puntis, Rugkasa, Forrest, Mitchell and Burns 6 The largest study to date, designed to look at the impact of introducing a case management system, involved 661 people with severe mental illness from Ohio and Maryland, USA, of whom 60% had a primary diagnosis of schizophrenia.Reference Lehman, Postrado, Roth, McNary and Goldman 7 Although a larger number of patients in the first cohort had had a change of case manager at 12 months, the team found no differences in levels of hospitalisation, satisfaction with care or social functioning between cohorts.
The National Audit of Schizophrenia is an audit of care received by people with schizophrenia and schizoaffective psychosis in England and Wales. 8 All providers of state-funded secondary care mental health services take part in the audit. The audit examines the quality of care that people receive against nationally agreed standards. Questions on changes in clinical staff were included in the second round of the audit and provided an opportunity to examine whether such changes are associated with differences in the quality of care that people with severe mental illness receive. We performed secondary analyses on the data from the audit to examine the proportion of people with schizophrenia who experienced changes in their key worker and/or psychiatrist over the preceding 12 months and whether such changes were associated with patient satisfaction and the quality of care that people received.
Method
Between August and November 2013, all 64 mental health trusts in England and Health Boards in Wales were asked to survey a random sample of 200 service users with an ICD-10 diagnosis of schizophrenia or schizoaffective disorder, who were aged 18 years or older and had been under the care of community mental health teams in the previous 12 months. Details of the methods used have been published elsewhere. 8 The content of the patient survey was based on national guidelines for the care of people with schizophrenia 9 and a quality standard on patient experience in mental health 1 and was developed with input from an expert reference group of users and providers of mental health services. Service users who gave feedback on a draft version of the questionnaire asked that questions about age and other demographic factors be removed because of concerns that potential respondents might be less likely to express their views if they thought this information could be used to identify them. However, three of the trusts that took part in the survey agreed to link survey forms with case-note audit data, which allowed us to compare the demographic characteristics of a sample of people who did and did not complete the questionnaire.
The survey contained two questions on relational aspects of continuity of care: ‘Has there been a change in your key worker or care coordinator in the last year?’ and ‘Has there been a change in your psychiatrist in the last year?’ To each question, patients were asked to indicate whether there had been no change, one change, or two or more changes to their key worker or psychiatrist. The survey also included a Patient Reported Experience Measure, the Patient Satisfaction QuestionnaireReference Shipley, Hilborn, Hansell, Tyrer and Tyrer 10 and a series of questions on access to services, and whether they had received recommended interventions and treatments for their physical and mental health.
We did not seek ethical approval for this national clinical audit. Neither the National Research Ethics Service nor the Ethics and Confidentiality Committee of the National Information Governance Board identified any issues with the methodology when we checked with them before the start of the audit.
Data analysis
We calculated the number and proportion of patients who reported no change, one change or more than one change in their key worker and/or psychiatrist. We then compared self-reported outcomes between those who reported no changes in key worker with those who reported one change and those who reported more than one change in key worker, and similarly with changes in psychiatrist. We used multilevel linear regression (patient satisfaction outcome) and multilevel logistic regression (all other outcome variables), with a random effect for NHS trust to estimate and control for clustering of the dependent variables within trusts, using GENLINMIXED in SPSS version 22. 11 For three of the outcome variables (access to key worker, family therapy and employment support), the variance between trusts was estimated as zero, and the random effect was therefore omitted from the model.
Results
A total of 3379 patients returned the survey, a response rate of 26.4% on 12 800 questionnaires (64 trusts × 200 questionnaires each). Demographic and clinical characteristics of those who did and did not respond to the survey in the three trusts from which these data were available are presented in Table 1. There were small trends for men to be more likely to respond than women, for those who were White to be more likely to respond, and for respondents to have had longer-term contact with services.

Most patients (n=3296, 97.5%) provided information about whether there had been a change in their key worker. The number and proportion of people reporting changes in their key worker and psychiatrist are presented in Table 2. In total, 1107 (41.9%) reported a change in their key worker and 1212 (36.8%) a change in their psychiatrist. Of the 1107 who reported a change in their key worker in the last 12 months, 525 (47.4%) also reported a change in their psychiatrist during this period.
Table 2 Number and proportion of patients reporting changes in key worker and psychiatrist during the previous 12 months (and range in the proportion across all 64 trusts)
| No change | One change | More than one change | ||||
|---|---|---|---|---|---|---|
| n (%) | Range | n (%) | Range | n (%) | Range | |
| Key worker | 1535 (58.1) | 25.0–75.0% | 829 (31.4) | 17.5–57.1% | 278 (10.5) | 0.0–23.1% |
| Psychiatrist | 2084 (63.2) | 33.3–61.5% | 902 (27.4) | 8.5–50.0% | 310 (9.4) | 0.0–25.9% |
There were marked differences in the proportion of people who reported changes in clinical staff across different service providers. In some trusts as few as a quarter of patients reported a change in key worker during the previous 12 months, whilst in others three-quarters of patients reported such a change. The proportion reporting a change in their psychiatrist was 27.4% and ranged from 8.5% to 50.0%. Although there was a significant difference between NHS trusts in the likelihood of a change in psychiatrist (random intercept variance = 0.08, P<0.01), there were no significant differences between NHS trusts in the likelihood of key worker changes (random intercept variance = 0.04, P=0.13). There were significant differences between NHS trusts in patients’ satisfaction with care, knowledge of how to access help at times of crisis and likelihood of having a care plan (random intercept P<0.05).
Associations between changes in key worker or psychiatrist, experiences of care and access to services are presented in Table 3. Compared with patients whose healthcare professional had not changed in the past 12 months, patients who had experienced more than one change of key worker or psychiatrist reported significantly lower treatment satisfaction, were less likely to feel they had been helped by services and were less likely to know how to access their key worker or how to access help appropriately at times of crisis. A single change of healthcare professional had significant, but smaller, negative effects on treatment satisfaction and feeling helped but no significant effect on knowing how to access help in a crisis.

s.d.=standard deviation.
There were also stronger associations between multiple compared with single changes in healthcare professional with process of care and interventions received (Table 4). Compared with patients with no change of healthcare professional, patients with more than one change in either their key worker or psychiatrist were less likely to feel involved in decisions about their medication or to have had a discussion about medication side-effects. Additionally, patients with more than one change in psychiatrist were less likely to have completed a care plan or had physical health checks completed.

Discussion
Data from this national cross-sectional survey of people treated for schizophrenia and schizoaffective psychosis show that changes in clinical staff that provide mental healthcare are common. We found clear associations between changes in clinical staff and a number of measures of patient experience and quality of care. Not only were patients who experienced changes in clinical staff less satisfied with the service they received, they were also less likely to report receiving care in keeping with recommended national guidelines. Differences between no change and just one change in psychiatrist or key worker were generally small, but when patients reported multiple changes, differences in outcomes were often marked. It is important if mental health services are to be effective that patients and carers have confidence that they can access effective help at times of crisis.Reference Holmes 12 – Reference Gibson, Hamilton and James 14 Patients who reported multiple changes in key worker were far less likely to report knowing who to contact at times of crisis, increasingly the likelihood of delays in ensuring that people receive the help that they need when they are most vulnerable. Concerns about poor physical health and premature mortality among people with psychosis have led to increased efforts to screen for cardiovascular disease and other physical health conditions among people with schizophrenia.Reference Thornicroft 15 , Reference Crawford, Jayakumar, Lemmey, Zalewska, Patel and Cooper 16 The results of this study show that people who have had multiple changes in their psychiatrist are less likely to report having had regular physical health checks. More than one change in either key worker or psychiatrist was also associated with patients reporting that they had not been involved in discussions about medication side-effects or decisions about treatment, factors which have been shown to influence attitudes to treatment among people with psychosis.Reference Hamann, Langer, Winkler, Busch, Cohen and Leucht 17 We did not find associations between changes in clinical staff and whether patients had received cognitive behavioural therapy and family therapy. Most of those who responded to the survey had had contact with mental health services for over a decade, and it is possible that if patients did receive these interventions, it was at an earlier stage of their contact with mental health services.
Strengths and limitations
Data for this study were collected from all state-funded mental health services across England and Wales, and the sample was large enough to have sufficient power to examine clinically important differences in patient experience and care. However, the audit, and therefore this analysis, has a number of limitations. We relied on data provided by patients to assess the quality of care received and have no data on clinician reported outcomes. It is possible that response bias affected the information that participants provided. However, the pattern of responses (such as stronger associations between medical aspects of care and changes in psychiatrist compared with associations with changes in key worker) suggests this was limited. Cross-sectional studies do not provide a strong basis for establishing causality, and we do not know whether factors other than changes in clinical staff are responsible for differences in patient experience and the other outcomes we assessed. Nonetheless, our finding of a dose–response relationship between the number of changes in clinical staff and quality of care, together with our finding that the strongest association was between multiple changes in staff and a patient knowing how to contact their key worker, strengthen the basis for believing that changes in clinical staff influence the quality of care that patients receive.
Implications for clinical practice
Our findings indicate that changes to staff providing care for people with schizophrenia could have negative impacts on various aspects of care, as well as patients’ overall perception of and satisfaction with the care they receive. Although it is unrealistic to suggest changes to staff should or could be avoided altogether, efforts should be made to maintain relational continuity of service provision whenever possible. Factors associated with frequent changes of clinical staff include workforce stability and the extent of use of temporary staff.Reference Belling, Whittock, McLaren, Burns, Catty and Jones 18 Over recent years, there has been considerable discussion about the costs and potential benefits of reorganising mental health services. These include a range of specialist community services and the development of separate teams for providing in-patient and out-patient care.Reference Omer, Priebe and Giacco 19 New research is being undertaken to examine the impact that these types of changes have on patient outcomes,Reference Giacco, Bird, McCrone, Lorant, Nicaise and Pfennig 20 but available evidence to date suggests that patients often find the resulting changes in staff providing their care difficult.Reference Begum, Brown, Pelosi, Crabb, McTaggart and Mitchell 21 The results of this analysis suggest that changes in clinical staff may also have negative effects on the quality of care that patients receive. Our findings provide support for national guidelines in England that people using community mental health services should be supported by staff from a single team with whom they have a continuous relationship. 1 Patients whose medical care is provided by rotating trainee are more likely to have experienced a change in their psychiatrist. It is essential that there is a proper handover when care is transferred from psychiatrist to another so that important information about current treatment and care is not lost.
