Substance abusers and psychiatric patients have a high degree of comorbid somatic disorders, such as cardiovascular diseases, diabetes, COPD and infections, but they are less frequently treated for their somatic disorders and have a high mortality rate (1, 2). In a number of medical conditions, mental symptoms may appear without any accompanying somatic ones, or the somatic symptoms can have their onset later in the course of disease than the mental ones. Examples include metabolic problems (3), vitamin B12 and folic acid deficiency (4) and primary hyperparathyroidism (5).
Diagnosis of a mental disorder presupposes that any organic cause of the symptoms can be excluded (6). A number of studies have thoroughly investigated patients in psychiatric outpatient clinics and revealed medical conditions that have directly caused or exacerbated mental disorders in a considerable proportion of the patients (7 – 9). Cautious estimates indicate that in at least 10 % of the patients, the mental symptoms are caused by somatic conditions.
The manual issued by the Directorate of Health for the regional psychiatric centres stipulates that the examination shall encompass mental, medical and psychosocial issues, and that the regional psychiatric centres must employ a sufficient proportion of specialists in medicine and psychology to handle this task, but without specifying any figures (10).
Staffing in general and the availability of senior consultants in particular vary between the regional psychiatric centres (11). The Norwegian Medical Association has voiced concerns regarding the availability of senior consultants at the regional psychiatric centres and claim that there needs to be a minimum staffing of one senior consultant for every three other specialist positions to ensure adequate psychiatric assessment and treatment of patients (12). Specialty registrars are here included in the other specialist positions. Figures from the Directorate of Health show the staffing at outpatient and inpatient units at the regional psychiatric centres and in specialised substance abuse units, but do not distinguish between different types of outpatient clinics (11).
The objective of this study was to investigate the availability of doctors in Norwegian outpatient clinics for general psychiatry and for substance abuse, the presence of routines for medical assessment of all patients and routines for collection of blood samples.
Material and method
An overview of the outpatient clinics was obtained with the aid of the hospital trusts’ websites, supplemented with information from the Free Hospital Choice scheme (www.frittsykehusvalg.no).
Altogether 136 outpatient clinics were identified and included in the study. Of these, 78 were general psychiatry outpatient clinics/teams, 18 were general psychiatry outpatient clinics that included a substance abuse team, and 40 were outpatient substance abuse clinics/teams. All clinics, represented by the head of clinic or a senior consultant, were contacted by email in the period December 2012 – May 2013. The questions were open-ended and the categorisation of responses was later undertaken by the author. The questions and categorisations are shown in Table 1.

The staffing by professionals at the regional psychiatric centres consists of personnel with university or university-college training (13). Therapists with university-college training mainly include nurses, social educators, social workers and child-welfare officers. The concept of «therapists with university-college training» is well established in the outpatient clinics and has been chosen as a collective designation for the above-mentioned professions.
Responses were de-personalised by assigning a number to each clinic. Registrations included only the health region to which the clinic belonged and the type of clinic in question.
The density of doctors was estimated by dividing the sum of all man-years worked by other professions (psychologists and staff with university-college training) by the number of man-years worked by doctors, including senior consultants and speciality registrars. Since the objective of the study was to determine whether the clinics had established any routines to reveal relevant somatic disorders, the questions referred only to availability of doctors and not of senior consultants.
A high figure means a low density of doctors. This method of estimation was used since this is the way in which the Norwegian Medical Association reports density of doctors (12). The Norwegian Medical Association finds that a sufficient staffing at the regional psychiatric centres amounts to three professionals per psychiatrist. I have chosen to define high density of doctors in outpatient clinics as three or fewer other professional man-years per doctor man-year, since specialty registrars will be able to identify somatic disorders to the same extent as senior consultants. However, this will correspond to a lower staffing by senior consultants than is recommended by the Norwegian Medical Association.
Three outpatient clinics for substance abuse reported that they currently had no doctor employed and were excluded from the analysis. One further outpatient clinic for substance abuse employed a doctor who was also working in the inpatient department, and the proportion could therefore not be estimated. This clinic was also excluded.
The study was submitted to the Regional Committee for Medical and Health Research Ethics, which concluded that no approval was necessary on their part.
Results
The response rate amounted to 90 % (123 out of 136 outpatient clinics), with the highest rate in South-Eastern Norway Regional Health Authority at 95 % (63/66) and Central Norway Regional Health Authority at 95 % (20/21), Northern Norway Regional Health Authority at 86 % (18/21) and Western Norway Regional Health Authority at 79 % (22/28). Among the general psychiatry outpatient clinics, the response rate amounted to 86 % (68/78), while the response rate among the outpatient clinics for substance abuse was 98 % (39/40).
Doctor density
Among the 119 outpatient clinics included, the number of other professional man-years (psychologists and staff with university-college training) per doctor man-year ranged from 1.3 – 140 (median 5.0; average 9.4, SD 17.5).
Altogether 38 (32 %) of the clinics reported to have a doctor density of three or fewer other professional man-years for each doctor man-year (high doctor density).
The doctor density in the various health regions and the different types of clinics are presented in Table 2.

Medical assessment
Six (5 %) of the clinics reported that all patients were examined by a doctor during the course of their treatment. Another 63 (53 %) of the clinics reported that all patients were assessed indirectly by a doctor upon admission and/or by an interdisciplinary team/treatment meeting (Table 2).
Routine blood samples
Altogether 23 (19 %) of the clinics reported to routinely collect blood samples at the initiation of treatment (Table 2).
Discussion
These results present a snapshot, but nevertheless indicate that there are major variations in the doctor density in outpatient clinics for general psychiatry and for substance abuse, and that the doctor density is lowest in the outpatient clinics for substance abuse. Furthermore, the figures indicate certain differences between the regions, but the figures are minor and there are major variations within the individual health regions. The questions may have been interpreted differently, and there is a possibility that the person who responded to the email may not have been fully informed about the staffing. This notwithstanding, the same tendency can be seen in the figures from the Directorate of Health (SAMDATA) (11), which confirm that there is still a long way to go before the goal established by the Norwegian Medical Association of having three other professional man-years for each psychiatrist has been achieved (12).
Although 69 (58 %) of the clinics maintained routines for direct or indirect medical assessment of all patients, only six (5 %) of them had routines ensuring that all patients come to see a doctor. In indirect assessments – i.e. that the doctor is present when the patient is admitted or in team meetings when the patient’s condition is discussed – it is obviously more difficult to establish an overview of the patient’s complete medical history, although it can be noted whether a GP has assessed the state of the patient’s health. A recently published article from Nord-Trøndelag county found that somatic health information was completely absent from 101 out of 155 referrals to a clinic for substance abuse (14). There are surprisingly small differences between the clinics that have a high doctor density and the other ones, although there is a tendency for more patients to be examined by a doctor in those clinics that have a high doctor density.
Routine collection of blood samples from patients initiating their treatment in outpatient clinics for general psychiatry or for substance abuse helps ensure a minimum somatic assessment. Blood samples can never provide exhaustive information on somatic health (15), but may reveal whether the mental symptoms are caused or exacerbated by somatic conditions such as metabolic problems (3), vitamin B12 and folic acid deficiency (4) or primary hyperparathyroidism (5). By devoting attention to somatic conditions at the start of outpatient treatment, an organic genesis of the symptoms can be excluded to a greater degree. Only 23 (19 %) of the outpatient clinics reported to have established routines for collection of blood samples. Nor were there any major differences between clinics that had a high doctor density and the remaining clinics.
Even though blood samples are not routinely collected, the doctors at the outpatient clinics may have established routines to exclude somatic disorders. It is nevertheless possible that many of the country’s outpatient clinics for general psychiatry and substance abuse are treating patients that ought to have had somatic follow-up instead and/or fail to recuperate because of a complicating somatic disorder that has gone undetected.
The results may indicate that a number of the outpatient clinics for general psychiatry and for substance abuse around the country are failing to comply with the DPS manual’s (10) requirement for medical examination of patients in order to obtain a thorough assessment that will lead to appropriate treatment. The low prevalence of systematic medical examinations ought to indicate that a comprehensive examination be made to identify the disorders from which these patients suffer and the extent to which they are being treated satisfactorily.
This study has a number of weaknesses. Since the figures have not been corrected for the population basis in the regions served by the outpatient clinics, nor for the number of patients who are in active treatment, the estimated doctor density will not indicate the adequacy of the staffing situation in general, but only reveal the relative distribution of doctors versus other groups of professions. Nor does it provide any information on the quality of the work they perform. The study could have been better planned, the clinics could have been provided with response categories to tick instead of open-ended questions, and the compliance with routines in practice is uncertain.
The strength of the study lies in its nationwide coverage and high response rate, which may have come about because the email was perceived as easy to respond to and the issues involved as relevant.
