[Consultative psychiatry in the general practice]

BACKGROUND

The high demand for mental health care is increasing the pressure on Dutch basic and specialized mental health care. Consultative psychiatry in primary care may help to support primary mental health care. These consultations are increasingly used nationwide. However, little is known about how this help takes shape in practice and what the experiences of both patients and caregivers are.

METHOD

We carried out a database and file study into the characteristics of the patients who received psychiatric consultation, in which we also examined the consultation questions of the general practitioners (GP) and the given advice. In addition, 15 semi-structured in-depth interviews were conducted with patients, general practitioners, mental healthcare nurse practitioners and psychiatrists, after which the transcripts were coded and analyzed thematically.

AIM

To explore for which patients the GP requests a psychiatric consultation, what the consultation questions are and the advice given, and to identify the experiences of patients and healthcare providers with consultative psychiatry in general practice.

RESULTS

The database study showed that consultative psychiatry was mainly used for patients with a psychiatric history, multiple psychiatric diagnosis and current psychopharmaceutical use. The consultation question usually concerned medication or treatment advice. In addition to advice regarding the consultation question, the psychiatrist often gave additional advice. Consultative psychiatry was experienced positively by both health care providers and patients due to the low threshold of the general practice, the mutual trust that is involved, the short waiting times compared to the second and third line psychiatry and the expertise of the psychiatrist.

CONCLUSION

Consultative psychiatry in general practice is widely applicable, but is mainly applied to patients with multiple psychiatric diagnoses and current psychopharmaceutical use. It is experienced as positive by both patients and healthcare providers.

[Starting insulin or not? And if so, which basal insulin?]

A 55-year-old patient with a BMI of 30 kg/m2 is referred for uncontrolled type 2 diabetes mellitus. His HbA1c-concentration is 71 mmol/mol, despite an initial 8% weight loss and treatment with metformin and glimepiride. The general practitioner proposes to start with insulin, but the patient refuses. We discuss whether there is a good alternative for insulin such as more weight loss and the addition of more drugs. Our patient then changes his mind and agrees to start insulin treatment. Basal insulin is usually recommended in cases like this.Since there are no significant differences between different types of available basal insulin, it seems reasonable to take price into account. Our patient achieved reasonable glucose control without weight gain using a combination of basal insulin and a GLP-1 receptor agonist.

The effect of a dermato-oncological training programme on the diagnostic skills and quality of referrals for suspicious skin lesions by general practitioners

Background

The rising incidence rates of skin cancer (SC) lead to an enormous burden on healthcare systems. General practitioners (GPs) might play an important part in SC care, but research has shown poor clinical recognition of SC, leading to a high rate of potentially unnecessary referrals.

Objectives

The aim of this study was to evaluate if a dermato‐oncological training programme (DOTP) for GPs improved their diagnostic skills and quality of referrals.

Methods

Out of 194 GPs in the Nijmegen area, 83 (42·8%) followed a DOTP on SC. Referrals from both a trained cohort (TC) and two cohorts of untrained GPs [untrained present cohort (UPC) and untrained historical cohort (UHC)] were included. Data on diagnostic skills, quality of referrals and the number of potentially unnecessary referrals were evaluated.

Results

A total number of 1662 referrals were analysed. The referral diagnosis was correct more often in the TC (70·3%) compared with the UPC (56·2%; P < 0·001) and the UHC (51·6%; P < 0·001). Furthermore, the TC also provided a better lesion description, mentioned a diagnosis more often in their referral letters and more often performed diagnostics before referral. In addition, fewer potentially unnecessary referrals were identified in the TC compared with the UPC (62·7% vs. 73·7%; P < 0·001) and the UHC (75·2%; P < 0·001).

Conclusions

GPs who followed a DOTP had better diagnostic skills and quality of referrals than untrained GPs, leading to fewer potentially unnecessary referrals. This might enhance a more efficient use of the limited capacity in secondary dermatological care and consequently lead to lower healthcare costs.

What is already known about this topic?

General practitioners (GPs) play an important part in skin cancer (SC) care and optimal recognition and referral are considered of vital importance to optimize SC care efficacy.

Previous research identified a rather poor clinical recognition of (pre)malignant skin tumours by GPs, leading to a high rate of potentially unnecessary referrals to dermatologists.

What does this study add?

GPs who followed a dedicated dermato‐oncological training programme had better diagnostic skills and quality of referrals than untrained GPs, leading to fewer potentially unnecessary referrals.

This might enhance a more efficient use of the limited capacity in secondary dermatological care and consequently lead to lower healthcare costs.

[Lower back pain: understanding it is more important than treating it]

Nonspecific lower back pain is frequently encountered in primary care, with 25-50% of cases following a chronic course. Over recent decades, a large body of research has focused on the effectiveness of both pharmacological and non-pharmacological treatments. However, hardly any effective interventions have been identified and the overall strength of evidence is low. We argue that the reason for these disappointing results lies in the 'nonspecific' nature of back pain. It is widely recognised that the causes for nonspecific back pain are not only biologically, but also psychologically and socially determined. Future research should emphasise aetiology and prognosis in order to enhance the development of tailored interventions.

The vegetative state/unresponsive wakefulness syndrome: a systematic review of prevalence studies

One of the worst outcomes of acquired brain injury is the vegetative state, recently renamed 'unresponsive wakefulness syndrome' (VS/UWS). A patient in VS/UWS shows reflexive behaviour such as spontaneous eye opening and breathing, but no signs of awareness of the self or the environment. We performed a systematic review of VS/UWS prevalence studies and assessed their reliability. Medline, Embase, the Cochrane Library, CINAHL and PsycINFO were searched in April 2013 for cross-sectional point or period prevalence studies explicitly stating the prevalence of VS/UWS due to acute causes within the general population. We additionally checked bibliographies and consulted experts in the field to obtain 'grey data' like government reports. Relevant publications underwent quality assessment and data-extraction. We retrieved 1032 papers out of which 14 met the inclusion criteria. Prevalence figures varied from 0.2 to 6.1 VS/UWS patients per 100 000 members of the population. However, the publications' methodological quality differed substantially, in particular with regards to inclusion criteria and diagnosis verification. The reliability of VS/UWS prevalence figures is poor. Methodological flaws in available prevalence studies, the fact that 5/14 of the studies predate the identification of the minimally conscious state (MCS) as a distinct entity in 2002, and insufficient verification of included cases may lead to both overestimation and underestimation of the actual number of patients in VS/UWS.

Limited evidence for effects of diet for type 2 diabetes from systematic reviews

OBJECTIVE

Systematic reviews are an appraised method to summarize research in a concise and transparent way, and may enable to draw conclusions beyond the sum of results of individual studies. We assessed the results, quality and external validity of systematic reviews on diet in patients with type 2 diabetes.

DESIGN, SETTING, SUBJECTS

We systematically searched for systematic reviews on nutritional interventions in patients with type 2 diabetes that used a reproducible search strategy in at least one major database that applied some form of quality assessment. We assessed quality and the external validity of the retrieved systematic reviews. Outcomes were defined as statistical meta-analyses or narrative results using a predefined and reproducible method.

RESULTS

Six systematic reviews met the inclusion criteria, investigating dietary interventions in general (n=3), chromium supplementation (n=1), fish-oil (n=1) or herbs and nutrition supplements (n=1). Quality assessment showed minimal/minor flaws in four cases and major/extensive flaws in two cases. All reviews had insufficient data needed to judge external validity. In reviews with minimal/minor flaws, we found beneficial effects of very-low-calorie diets and fish-oil supplements. However, the external validity of these results could not be assessed sufficiently.

CONCLUSIONS

Systematic reviews largely failed to produce knowledge beyond the sum of the original studies. Furthermore, judgment of external validity was hampered in most cases owing to missing data. To improve the quality and usefulness of systematic reviews of dietary interventions, we recommend the application of more focused research questions, but with broader inclusion criteria, for example, the use of observational studies.

Eating behaviour and adherence to diet in patients with Type 2 diabetes mellitus

AIM

To assess restrained, emotional and external eating behaviour in patients newly diagnosed with Type 2 diabetes compared with the general population, and to assess the relationship of eating behaviour to changes in fat and energy.

METHODS

We assessed emotional, external, and restrained eating behaviour and measured fat and energy intake in a cohort of patients with newly diagnosed Type 2 diabetes. Data from a comparable sample of the general population served as reference figures. We calculated correlation coefficients of the three different types of eating behaviour at diagnosis between: (i) energy and fat intake at diagnosis and (ii) changes in energy and fat intake between diagnosis and both 8 weeks and 4 years later. In addition, we used a stepwise multiple regression model with energy and fat intake or changes in energy and fat intake as dependent variables.

RESULTS

The distribution of the three types of eating behaviour was similar in patients with Type 2 diabetes and the general population. Emotional and external eating was associated with increased intake of energy and fat. Conversely, restrained eating showed an inverse correlation with energy and fat intake. External eating, but not emotional eating, showed a statistically significant relation with a decrease in energy intake in women. We found no statistically significant correlations between eating behaviour (measured at diagnosis) and changes in energy and fat intake between diagnosis and 4 years.

CONCLUSIONS

Patients newly diagnosed with Type 2 diabetes have similar eating behaviour compared with the general population. At diagnosis, external eating behaviour and emotional eating behaviour are associated with high-energy intake and restrained eating behaviour with low-energy intake. Women with high scores for emotional eating behaviour seem to be less able to make initial dietary changes after being diagnosed and having received dietary advice.

Nutritional deficiency in general practice: a systematic review

OBJECTIVE

Nutritional deficiency is an independent risk factor for mortality. Despite its clinical relevance, the prevalence in a primary care setting is poorly documented. We performed a systematic review of reported prevalence and clinical assessment of nutritional deficiency in general practice.

METHODS

From MEDLINE, Current Contents and EMBASE, we derived articles and checked the initially included ones for references on prevalence data. Of the eligible articles, we assessed the quality of research and results.

RESULTS

We finally included eight studies. The prevalence ranged from 0 to 13%. However, the study populations were heterogeneous and all studies contained methodological flaws, especially selection bias. In addition, the clinical assessment differed between studies.

CONCLUSION

Literature on the prevalence of nutritional deficiency within general practice is rare and provides disputable prevalence assessments.

Nutritional deficiency in Dutch primary care: data from general practice research and registration networks

OBJECTIVE

To explore incidence and prevalence rates of nutritional deficiency in adults in general practice.

METHODS

Six Dutch general practice research and registration networks supplied incidence and prevalence rates of nutritional deficiency by the International Classification of Primary Care (ICPC) or 'E-list' labels ('loss of appetite, feeding problem adult, iron, pernicious/folate deficiency anaemia, vitamin deficiencies and other nutritional disorders, weight loss'). In case of disease-related nutritional deficiency, we asked whether this was labelled separately ('co-registered') or included in the registration of the underlying disease.

RESULTS

'Iron deficiency anaemia' had highest incidence (0.3-8.5/1000 person years), and prevalence rates (2.8-8.9/1000 person years). Nutritional deficiency was mostly documented in the elderly. In two networks 'co-registration' was additional, two only documented the underlying disease and two did not specify 'co-registration'. No clear difference was found between networks considering the difference in 'co-registration'.

CONCLUSION

Nutritional deficiency is little documented in general practice, and generally is not registered separately from the underlying disease.
