A randomized controlled trial of problem solving for anxiety, depression and life difficulties by community psychiatric nurses among general practice patients: background and method

Moving from collision to integration

Combining research approaches, commonly referred to as ‘mixed methods’, has the potential to lead to greater insights than would be gained by one approach alone. The discussion in this paper draws on the personal experience of conducting interrelated studies that adopted different methods, underpinned by different methodological positions. In the conduct of the research, several roles were occupied by members of the research team and, together with the mixed methods, gave rise to a number of issues in the conduct and implementation of research. The particular tensions identified are likely to be transferable to other contexts. Key to working with mixed methods is the need for researchers to acknowledge the alternative conceptions of knowledge and reflect on their position in relation to the range of possibilities. It is suggested that continued conflation of particular concepts, i.e. method and paradigm, acts as a barrier to meaningful interdisciplinary working and true integration of insights gained from combined approaches.

Counselling for mental health and psychosocial problems in primary care

BACKGROUND

The prevalence of mental health and psychosocial problems in primary care is high. Counselling is a potential treatment for these patients, but there is a lack of consensus over the effectiveness of this treatment in primary care.

OBJECTIVES

To assess the effectiveness and cost effectiveness of counselling for patients with mental health and psychosocial problems in primary care.

SEARCH STRATEGY

To update the review, the following electronic databases were searched: the Cochrane Collaboration Depression, Anxiety and Neurosis (CCDAN) trials registers (to December 2010), MEDLINE, EMBASE, PsycINFO and the Cochrane Central Register of Controlled Trials (to May 2011).

SELECTION CRITERIA

Randomised controlled trials of counselling for mental health and psychosocial problems in primary care.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised data extraction sheet by two reviewers. Trials were rated for quality by two reviewers using Cochrane risk of bias criteria, to assess the extent to which their design and conduct were likely to have prevented systematic error. Continuous measures of outcome were combined using standardised mean differences. An overall effect size was calculated for each outcome with 95% confidence intervals (CI). Continuous data from different measuring instruments were transformed into a standard effect size by dividing mean values by standard deviations. Sensitivity analyses were undertaken to test the robustness of the results. Economic analyses were summarised in narrative form. There was no assessment of adverse events.

MAIN RESULTS

Nine trials were included in the review, involving 1384 randomised participants. Studies varied in risk of bias, although two studies were identified as being at high risk of selection bias because of problems with concealment of allocation. All studies were from primary care in the United Kingdom and thus comparability was high. The analysis found significantly greater clinical effectiveness in the counselling group compared with usual care in terms of mental health outcomes in the short-term (standardised mean difference -0.28, 95% CI -0.43 to -0.13, n = 772, 6 trials) but not in the long-term (standardised mean difference -0.09, 95% CI -0.27 to 0.10, n = 475, 4 trials), nor on measures of social function (standardised mean difference -0.09, 95% CI -0.29 to 0.11, n = 386, 3 trials). Levels of satisfaction with counselling were high. There was some evidence that the overall costs of counselling and usual care were similar. There were limited comparisons between counselling and other psychological therapies, medication, or other psychosocial interventions.

AUTHORS' CONCLUSIONS

Counselling is associated with significantly greater clinical effectiveness in short-term mental health outcomes compared to usual care, but provides no additional advantages in the long-term. Participants were satisfied with counselling. Although some types of health care utilisation may be reduced, counselling does not seem to reduce overall healthcare costs. The generalisability of these findings to settings outside the United Kingdom is unclear.

Systematic review of interventions delivered by UK mental health nurses

The effectiveness of mental health nurse interventions has not been generally established in the literature. In this systematic review, randomised controlled trials (RCTs) were identified, undertaken in the United Kingdom, where mental health interventions delivered by mental health nurses had been evaluated. The main online literature databases were searched, key journals were hand searched and contact was made with key authors, resulting in a total of 52 studies, involving at least 7172 service users. Data were extracted and then all identified trials were assessed for inclusion by two reviewers. The results showed that in the UK, mental health nurses are involved in the delivery of a wide range of interventions in a variety of clinical health settings, with broadly positive results.

Cost-effectiveness of referral for generic care or problem-solving treatment from community mental health nurses, compared with usual general practitioner care for common mental disorders: Randomised controlled trial

BACKGROUND

UK general practitioners (GPs) refer patients with common mental disorders to community mental health nurses.

AIMS

To determine the effectiveness and cost-effectiveness of this practice.

METHOD

Randomised trial with three arms: usual GP care, generic mental health nurse care, and care from nurses trained in problem-solving treatment; 98 GPs in 62 practices referred 247 adult patients with new episodes of anxiety, depression and life difficulties, to 37 nurses.

RESULTS

There were 212 (86%) and 190 (77%) patients followed up at 8 and 26 weeks respectively. No significant differences between groups were found in effectiveness at either point. Mean differences in Clinical Interview Schedule - Revised scores at 26 weeks compared with GP care were -1.4 (95% CI -5.5 to 2.8) for generic nurse care, and 1.1 (-2.9 to 5.1) for nurse problem-solving. Satisfaction was significantly higher in both nurse-treated groups. Mean extra costs per patient were 283 pound (95% CI154-411) for generic nurse care, and 315 pound (183-481) for nurse problem-solving treatment.

CONCLUSIONS

GPs should not refer unselected patients with common mental disorders to specialist nurses. Problem-solving should be reserved for patients who have not responded to initial GP care.

Nurse prescribing and the enhancement of mental health services

Abstract

Mental health nurses are relative latecomers to nurse prescribing. This is primarily because nurse prescribing has been seen as more appropriate for general nurses, particularly those working in the community or primary care. Pharmacists and psychiatrists were concerned about the complexity of prescribing for clients with mental health problems and felt that the training of mental health nurses and their clinical experience did not fit them to take on a prescribing role. These, and other impressions, may have influenced which groups of nurses were first selected to become nurse prescribers. However, recent studies have indicated that mental health nurses add considerably to the effectiveness of assessments and care plans, and that they are in an ideal position to integrate drug treatments with a wide range of non-pharmacological therapies knowledgeably, safely, effectively and in a manner that is acceptable to the patient. They have also been found to have an important role to play in monitoring the side effects of drugs and in providing education about medication, and in maintaining a therapeutic alliance with clients on long-term drug treatment. Whatever the limitations, mental health nurses as prescribers may still be deemed to have by some professional groups, and even by themselves, at this stage in the evolution of nurse prescribing, it is now inevitable that they will play a significant part in the overall improvement of mental health services during this decade. They are likely to challenge the existing prescribing practices and help in identifying the conditions under which medication is most therapeutic.

Paraprofessionals for anxiety and depressive disorders

BACKGROUND

The established mental health care system does not have the resources to meet the extensive need for care of those with anxiety and depressive disorders. Paraprofessionals partially replacing professionals may be cost-effective.

OBJECTIVES

To investigate the effectiveness of any kind of psychological treatment for anxiety and depressive disorders performed by paraprofessionals compared with professionals, waiting list or placebo condition. To examine whether the results apply to clinically significant anxiety and depressive disorders of referred patients with a psychiatric history and/or whose illness has lasted two years or more.

SEARCH STRATEGY

CCDANCTR-Studies using the following terms: (paraprofessional* or para-professional* or non-professional* or non-professional* or peer or volunt*); EMBASE (ExerptaMedica), MEDLINE and PsycINFO, all years published, key words: para-/paraprofessional, non-/nonprofessional, rand*, respectively psy*; citation lists of articles reviewing the subject and included studies; correspondence with authors of controlled studies and review reports on the subject.

SELECTION CRITERIA

Randomised controlled trials that used symptom measures, and compared the effects of psychological treatments given by paraprofessionals (mental health care workers, paid or voluntary, unqualified with respect to the psychological treatment) with psychological treatments given by professionals, and with waiting list or placebo condition.

DATA COLLECTION AND ANALYSIS

The standard mean difference was used to pool continuous data from each trial, and odds ratios were used to pool dichotomous data, using a random effects model. The generic inverse variance method was used for combining continuous and dichotomous data. The effect of low quality studies and the use of self-rated versus observer-rated measures were tested, and subgroup analyses were performed for differences between depression and anxiety diagnosis, paraprofessionals with/without professional background, group/individual intervention, length of follow-up and gender (post-hoc subgroup analysis).

MAIN RESULTS

Five studies, all using self-report measures, reported five comparisons of paraprofessionals versus professionals (n=106) and five comparisons of paraprofessionals versus control condition (n=220). No differences were found between paraprofessionals and professionals (SMD=0.09, 95% CI -0.23 to 0.40, p=0.58; no significant heterogeneity). Studies comparing paraprofessionals versus control reported mixed continuous and dichotomous data showed a significant pooled effect in favour of paraprofessionals (OR=0.34, 95% CI 0.13 to 0.88, p=0.03), but heterogeneity was indicated (I(2)=60.9%, Chi(2)= 10.24, df=4, p=0.04). After correction for heterogeneity and removing one study of low quality, the pooling of data from three studies (n=128; mixed gender and women only) indicated no significant difference in effect between paraprofessionals and professionals (SMD=0.13, 95% CI -0.39 to 0.64; p=0.63) and a strongly significant pooled effect for three studies (n=188; women only) favouring paraprofessionals over the control condition (OR=0.30, 95% CI 0.18 to 0.48, p<0.00001), and homogeneity indicated between studies (I(2)=0%, Chi(2)=0.47, df=2, p=0.79).

AUTHORS' CONCLUSIONS

The few studies included in the review did not allow conclusions about the effect of paraprofessionals compared to professionals. Pooling data from three studies, involving women only, indicated a significant effect for paraprofessionals (all volunteers) compared to no treatment. The evidence to date may justify the development and evaluation of programs incorporating paraprofessionals in treatment programs for anxiety and depressive disorders.

Aspects of the relationship between doctors and depressed patients that enhance satisfaction with primary care

Depression will be the second most common threat to health by the end of the next decade. The incidence of depression in primary care is already high. This has serious implications for the types of services available, the range of personnel who deliver them and the extent to which patients are helped by the treatments provided. Research reveals that approximately two-thirds of patients with depression are treated with medication, although it is not known how effective medication is in the long term. It would appear that the relationship between the patient and prescriber is a highly significant factor in determining whether or not patients adhere to treatment regimens and to what extent they improve. This study used a qualitative approach to identify how patients treated with medication for their depression perceived the relationship with their prescribing clinician, what kinds of information and advice they received and what they wanted. Several aspects of the helpful relationship are identified, such as the characteristics and behaviour of the clinician, as well as the way in which information is imparted. The frequency of monitoring consultations and patients' perceptions of their importance were also examined. The issue of stigma, particularly self-stigma and what can be done to prevent it, is discussed. The paper concludes with suggestions for improving the quality of primary care for patients' prescribed medication for depression, and especially for making maximum use of the initial consultation. The main implication for mental health nurses is that central to all interventions for depression is the primacy of the relationship, without which, clients' belief in treatment is diminished.
