Psychiatric consultation in somatization disorder. A randomized controlled study

Somatization Disorder

There are many new developments regarding somatization disorder, which is among the most difficult and cumbersome of the psychiatric disorders encountered in neurology practice. Diagnostic criteria have been revised to facilitate clinical care and research. The differential diagnosis includes neurologic disorders (eg, multiple sclerosis, epilepsy), systemic medical disorders, and other psychiatric disorders (eg, mood and anxiety disorders, conversion disorder, malingering, and factitious disorder). Many patients have one or more of these illnesses comorbid with somatization disorder. Finally, somatization disorder demands creative biopsychosocial treatment planning by the neurologist, psychiatrist, and other health professionals.

Cognitive behavior therapy for somatization disorder: a preliminary investigation

Patients diagnosed with somatization disorder have high rates of disability and often prove refractory to treatment. This preliminary investigation examines the effect of a 10-session cognitive behavior therapy (CBT) protocol on the physical discomfort and disability of severely impaired somatizers. The severity of patients' physical discomfort and disability was assessed at baseline, post-treatment, and eight months following treatment. Patients reported significant improvement in symptomatology and physical functioning between baseline and post-treatment as well as between baseline and follow-up. The findings suggest that CBT might benefit patients diagnosed with somatization disorder and should be subjected to a controlled treatment trial.

Risk Factors for Complex Care Needs in General Medical Inpatients: Results From a European Study

The authors linked admission risk factors to a series of indicators for complex care delivery to enable detection of patients in need of care coordination at the moment of admission to the general hospital. The authors found 13 risk factors to be predictive of more than one indicator of care complexity. An admission risk screening procedure to detect patients in need of care coordination should focus on these risk factors and should include predictions made by doctors and nurses at admission and information collected from the patient and the medical chart.

A health services perspective on delivery of psychiatric services in primary care including internal medicine

Serious problems persist in the recognition and treatment of psychiatric problems in primary care despite multiple interventions directed at correcting these problems. Improved outcomes depend on improved recognition, and screening instruments need to be streamlined tremendously to be accepted by primary care providers. Publication of guidelines and physician education, although essential for improved care, are probably insufficient to implement guidelines-based care. Improvements in psychiatric outcome appear to depend on the level of intensity of the intervention employed. Continued research is needed to determine the most effective type of educational intervention and more widely applicable quality improvement processes. Broad-based changes in health service delivery focusing on the true integration of mental health services with general medical care are required to bring about meaningful, effective change. Ongoing changes in physician training programs (combined primary care/psychiatry programs) may facilitate implementation of guideline-based psychiatric care in medical settings, but the full impact of these changes is not likely to be felt for several years.

Somatizing frequent attenders in primary health care

OBJECTIVE

The aim of this case-control study was to investigate the association of somatization with frequent attendance in primary health care.

METHODS

Frequent attenders in a health center (FAs) (N=112) and age- and sex-matched controls (COs) (N=105) constituted the study series. Data were collected from annual statistics, medical records, postal questionnaires and personal interviews. Psychological distress was assessed using Symptom Checklist-36 (SCL-36), alexithymia was measured with Toronto Alexithymia Scale-20 (TAS-20) and hypochondriasis was screened with Whiteley Index (WI).

RESULTS

About one-third of FAs were somatizers when a cut-off point of eight symptoms on the SCL-36 somatization subscale was used as a criterion. The significant association of somatization with frequent attendance disappeared in multivariate analyses when adjusted for age, sex and chronic somatic illnesses. Hypochondriacal beliefs and psychiatric comorbidity were connected with FAs' somatization. Hypochondriacal beliefs explained somatizers' frequent attendance. A significant interaction effect between somatization and hypochondriacal beliefs was found when explaining frequent attendance.

CONCLUSION

The results emphasize the need to use a comprehensive approach of somatization, including hypochondriacal beliefs, when treating somatizing FA patients in primary health care.

Talking tumours: histories from sequences

The history of a tumour is currently inferred from its morphology. However, progression may be variable between similar appearing tumours, and some critical events may be difficult to see. It has become increasingly apparent that histories are also written within sequences. Every tumour likely records its own progression within its genome. In the future, it may be possible to read the past based on these sequences. A critical issue is whether these autobiographies will recapitulate morphology or whether they reveal unexpected ghosts.

Psychiatric symptoms and medical utilization in primary care patients

In two studies, the authors evaluated the impact of psychiatric disorders on medical care utilization in a primary care setting. In the first study, 526 consecutive patients in a teaching hospital primary care practice completed the 18-item RAND Mental Health Inventory to identify clinically significant depression and/or anxiety and a questionnaire about the use of psychiatric treatment and psychoactive medications. The medical utilization of those patients defined as depressed and/ or anxious was compared with those defined as not depressed and/or anxious. Patients identified as depressed and/or anxious reported significantly increased medical utilization, but this was not confirmed by the hospital's computerized record system. In the second study, the authors analyzed medical care utilization for the years before and after the first outpatient psychiatry appointment of a sample of 91 patients referred from the same primary care practice to the hospital's outpatient psychiatry clinic over a 1-year period. In both studies there was not a statistically significant difference in medical utilization among those patients receiving psychiatric treatment. The findings demonstrate the difficulties in examining cost offset in a primary care population and raise questions about it as a realistic outcome measure of the effect of psychiatric treatment.

Unexplained symptoms in primary care: perspectives of doctors and patients

This study evaluated unexplained symptoms in primary care from the perspective of both patients and physicians. The data were obtained from two 1998 statewide surveys, one targeting Medicaid patients and the other all primary care physicians in the state. There were 439 patients who responded (45% response rate) and 280 primary care physicians who responded (33% response rate). Half of the patients and half of the physicians were in non-metropolitan counties. Half of the patients reported unexplained symptom usually or always, and 75% of whom sought help for these symptoms. Fifty-two percent of these patients believed their physician was very concerned about their unexplained symptoms. Eighty percent of them rated their physician as providing the best possible care compared to only 49% of patients whose physician did not care about their unexplained symptoms (P=.001). Among the physicians, only 14% reported very good or excellent satisfaction with managing unexplained symptoms as compared to 44% who claimed similar satisfaction in managing psychological problems. Physicians who saw themselves as more effective in dealing with somatoform symptoms were more likely to be in solo practice (P<.005), or in the same location for at least five years (P=.04). Residence in a nonmetropolitan county did not affect patient reporting of symptoms, patient perception of physician concern about symptoms, or physician satisfaction in managing these symptoms. These results indicate the prevalence and importance of unexplained symptoms in the Medicaid population and the comfort of physicians in managing these symptoms. There is an unmet need among primary care physicians to learn how to manage patients with unexplained symptoms.

Child and adolescent psychiatry in general children's hospitals. A survey of chairs of psychiatry

This article characterizes the academic, administrative, clinical service, and fiscal characteristics of departments of psychiatry in traditional children's hospitals to determine the characteristics of fiscally successful programs. A survey of chairs of psychiatry from short-term general children's hospitals was conducted based on 38 questions addressing the descriptive characteristics of their respective departments. The characteristics of psychiatry programs identified as fiscally successful were compared to those of programs that required subsidy. Nine of 45 eligible children's hospitals (20%) did not have a department or section of psychiatry, and surveys were returned by 35 of 36 department chairs (97% response). Considerable variation exists in the academic, administrative, clinical services, and fiscal characteristics of programs, although over half are operating at a deficit. Fiscal success was associated with availability of inpatient and intermediate levels of psychiatric care, better integration of the psychiatry program within the children's hospital, and adequate fiscal information being provided to the psychiatry chair. Additional research regarding the potential of psychiatric services to generate clinical success and cost savings is warranted. Pediatric health care professionals and third-party payers should be educated regarding the relevance of psychiatric services within children's hospitals and in physically ill children.

On-site mental health workers in primary care: effects on professional practice

BACKGROUND

Mental health problems are common in primary care and mental health workers (MHWs) are increasingly working in this setting. In addition to treating patients, the introduction of on-site MHWs may lead to changes in the clinical behaviour of primary care providers (PCPs).

OBJECTIVES

To assess the effects of on-site MHWs in primary care on the clinical behaviour of primary care providers (PCPs).

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (18-22 June 1998), the Cochrane Controlled Trials Register (18-22 June 1998), MEDLINE (1966 to 1998), EMBASE (1980 to 1998), PsychInfo (1984 to 1998), CounselLit (18-22 June 1998), NPCRDC skill-mix in primary care bibliography, and reference lists of articles.

SELECTION CRITERIA

Randomised trials, controlled before and after studies and interrupted time series analyses of MHWs either replacing PCPs as providers of mental health care ('replacement' models) or providing collaborative care/support to PCPs in managing patients' mental health problems ('consultation-liaison' models). The participants were primary care providers. The outcomes included objective PCP behaviours such as diagnosis, prescribing and referral.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed study quality.

MAIN RESULTS

Thirty-eight studies were included involving more than 460 PCPs and more than 3880 patients. There was some evidence that 'replacement' model MHWs achieved significant short-term reductions in PCP psychotropic prescribing and mental health referral, but the effects were not reliable. Consultation rates were also reduced, but with even less evidence of a consistent effect. There were no indirect effects in prescribing behaviour on the wider population and no consistent pattern to the impact on referrals. 'Indirect' effects on PCP consultation rates were not assessed. There was some evidence that 'consultation-liaison' model MHWs had a direct effect on PCP prescribing behaviour when used as part of complex, multifaceted interventions. Few studies examined the 'indirect' effects of such interventions, and those that did failed to provide evidence that 'direct' effects were generalisable to the wider population or endured once the 'consultation-liaison' intervention was removed.

REVIEWER'S CONCLUSIONS

This review does not support the hypothesis that adding MHWs to primary care provider organisations in 'replacement' models causes a significant or enduring change in PCP behaviour. 'Consultation-liaison' interventions may cause changes in psychotropic prescribing, but these seem short-term and limited to patients under the direct care of the MHW. Longer-term studies are needed to assess the degree to which demonstrated effects endure over time.

Interventions to improve provider diagnosis and treatment of mental disorders in primary care. A critical review of the literature

The authors conducted a critical review of the literature on interventions to improve provider recognition and management of mental disorders in primary care, searching the MEDLINE database for relevant articles published from 1966 through May 1998 and finding 48 usable controlled studies (27 randomized controlled trials and 21 quasi-experimental studies). Improved diagnosis of mental disorders was reported in 18 of 23 (78%) of the studies examining this outcome and improved treatment in 14 of 20 studies (70%); clinical improvement in psychiatric symptoms or functional status was documented in 4 of 11 and 4 of 8 (36% and 50%, respectively). Considerable study heterogeneity precluded subjecting the literature synthesis to a formal meta-analysis of pooled results; the authors were therefore unable to demonstrate an association between efficacy of an intervention and any specific variables. A variety of interventions and further research may be effective in improving the recognition and management of mental disorders in primary care.

Implications of the Balanced Budget Act of 1997 for general hospital psychiatry inpatient units providing medical and psychiatric services

Since 1983, the Tax Equity and Fiscal Responsibility Act (TEFRA) of 1982 has determined payment for services in most psychiatry units located in general hospitals. This system provided reimbursement on a cost-per-discharge basis. In 1997, a Balanced Budget Act (BBA) was passed by Congress which has replaced the TEFRA system of 1982 (H.R 2015). As a result of this law, many general hospital psychiatry units, particularly those that address the needs of elderly patients with high levels of medical comorbidity, will experience a reduction in their reimbursement when compared with the old TEFRA system. This reduction will average 7.8% and affect up to 84% of health care organizations. Those with higher TEFRA target amounts, such as is found with most general hospital programs, will have proportionately greater reductions. This article summarizes legislation affecting Medicare reimbursement and suggests a service reorganization approach that would allow billing to both medical and psychiatric payers. Finally, it encourages active participation in psychiatric access and quality standards development and with legislation, such as The Medicare Psychiatric Hospital Prospective Payment System Act of 1999.

Heavy general hospital case notes: a simple case-finding method for psychiatric problems

Objectives: To identify whether a simple marker of nonpsychiatric health service contact (weight of general hospital case notes) is helpfulin identifying patients with evidence of psychiatric disorder in a medical and surgical population.

Method: Hospital case note review identifying evidence of past and current psychiatric disorder in patients with heavy, medium and low weight case notes. Responses to letters to general practitioners and review of local psychiatric hospital records were used to validate findings. Setting: A large general teaching hospital in the centre of Leeds, UK. Subjects: Random sample of 240 patients aged 16-65 attending general hospital medical or surgical teams as an inpatient or day patient between April 1, 1991 and March 31, 1992. Patients whose index admission was to the gynaecology or obstetrics unit were excluded. Main outcomes: Non-psychiatric service contact was measured by case note weight and thickness, lifetime admissions and number of consultants seen. Psychiatric disorder was identified using global judgements based on a standardised assessment of the case notes, and also general practitioner statements of current or past psychiatric disorder and record of contact with psychiatric services.

Results: In a detailed examination of 75 cases, 92% of patients with lightweight notes had solely physical factors to account for their presentations, compared to 88% in the middleweight group and 64% in the heavyweight group. Heavier case notes more often contained comments about psychiatric problems affecting the physical presentation (lightweight 8%; middleweight 20%; heavyweight 64%). Patients with heavy case notes more often had a history of contact with psychiatric services as confirmed by the GP or contact at local psychiatric hospitals (lightweight 28% middleweight 24% heavyweight 48%). Amongst the heaviest service users, patients with a psychiatric problem had seen a median of 12.0 lifetime consultants compared to 8.5 in those where a purely physical cause was present.

Conclusions: Patients who have heavy hospital case notes are more likely to have evidence of psychiatric disorder than those with lower levels of hospital contact and this is more likely to have an impact on their physical presentation and clinical course as judged by case note review using structured assessment criteria.

Pragmatic randomised controlled trials in psychiatry

BACKGROUND

Randomised controlled trials (RCTs) are the most important method of evaluating new treatments and treatment policies. Despite this, there are relatively few large pragmatic RCTs in psychiatry.

AIMS

To explore the main advantages of large pragmatic RCTs and the obstacles to performing them in psychiatry.

METHOD

A narrative review of literature on pragmatic RCTs with examples drawn from psychiatry and other medical specialities.

RESULTS

Obstacles to performing pragmatic RCTs in psychiatry include the complexity of psychiatric interventions, the complexity of outcomes used in psychiatry and the difficulties of blinding subjects and investigators to some psychiatric interventions.

CONCLUSIONS

Researchers need to frame questions in a form that is relevant to clinicians and to convince clinicians to cooperate in simple large pragmatic trials.

Hypochondriasis, somatization, and perceived health and utilization of health care services

The authors determined the different effects of hypochondriasis and somatization on health perceptions, health status, and service utilization in a primary care population. The subjects with hypochondriacal responses (HR) on the Illness Attitudes Scales or high somatic concern (HSC) on the Symptom Questionnaire had a worse perception of health and variably used more health services than the control subjects, even though the HR and HSC subjects had the same level of chronic medical disorders. Regression analyses determined that somatization contributed more to negative health perception and service utilization than did hypochondriasis, although an interaction between the two contributed to the use of psychiatric care. The authors discuss the boundary between hypochondriasis and somatization for its implications for research and clinical practice.

Somatization in primary care. Prevalence, health care utilization, and general practitioner recognition

To study the prevalence of somatoform disorders (SDs) in primary care, a questionnaire including the modified 25-item version of the Symptom Checklist-90 was administered to 191 patients consecutively consulting their family physician. A stratified sample of the patients was interviewed with the Schedules for Clinical Assessment in Neuropsychiatry. The study showed that 22.3% (confidence interval [CI]: 95%: 16.4-28.1) of the patients fulfilled the diagnostic criteria for an International Classification of Diseases--10th Revision (ICD-10) SD, excluding SD, unspecified, and 57.5% (CI: 95%: 50.5-64.5) for DSM-IV SD. But 30.3% met the criteria (CI: 95%: 23.8-36.9) when the DSM-IV Not Otherwise Specified (NOS) diagnostic group is excluded. The most frequent ICD-10 diagnosis was autonomous dysfunction, for which 14.1% of the patients fulfilled the criteria, whereas the prevalence of the other somatoform diagnosis was between 3.0% and 8.1%. The most frequent DSM-IV diagnoses were SD NOS and undifferentiated SD, which 29.93% and 27.3% of the interviewed patients, respectively, received, whereas the prevalence of the other diagnoses was between 1.0% and 8.1%. A high comorbidity between SDs and other mental disorders was found. The general practitioners identified between 50% and 71% of the patients with an ICD-10 SD and between 36% and 48%, according to DSM-IV criteria. Patients with SDs used more nonpsychiatric health care facilities than other patients (P = 0.01).

Gulf War illnesses: causation and treatment

Soldiers returning from the Gulf War in 1991 described a range of symptoms, including some consistent with the chronic fatigue syndrome, fibromyalgia, and multiple chemical sensitivity. Well-defined adverse health events attributable to service in the Gulf occurred. However, controlled epidemiological studies in Gulf War veterans and controls describe significant excesses of symptoms that were not clearly associated with pathologic disease. At least 12% of veterans currently receive some form of disability from the Department of Veterans Affairs. A number of reports outline theories proposed to explain the excess, but few are scientifically supported. Management guidelines for this spectrum of disorders resembles that of many of "emerging overlap syndromes," including multiple chemical sensitivity, chronic fatigue syndrome, and fibromyalgia. They include the establishment of a trusting doctor-patient relationship, negotiations around a common ground of scientific and etiologic beliefs, non-labeling of the disorder, and work toward recovery in the absence of clear etiologic answers.

Somatization in Family Practice: Comparing 5 Methods of Classification

BACKGROUND: It has been suggested that patients with somatoform disorders are high utilizers of medical care, yet interpretation of studies has been difficult because of variant methods of diagnosis. The goal of this study was to compare 5 different methods of classification on the same group of subjects and to examine prevalence rates of somatoform disorders and medical utilization. METHOD: Subjects completed a demographic questionnaire in the physician's office and the somatization section of the Diagnostic Interview Schedule (DIS) by telephone. Subsequently, their medical charts were examined. Using the 5 methods of diagnosis, somatizers were compared with nonsomatizers for level of utilization of medical services. The setting was a medical school-based family practice residency training center. Participants were 119 patients waiting to see their family doctors. The main outcome measures were prevalence of somatization symptoms and chart information (utilization, number of health problems). RESULTS: One subject met the Diagnostic and Statistical Manual (DSM-IV)-based DIS criteria for somatization disorder. With the Bucholz modification for scoring the DIS, 10 subjects were diagnosed with somatization disorder. With the abridged Escobar criteria of 6 symptoms, 7 subjects met diagnostic criteria, while 28 met the criteria for multisomatoform disorder of 3 symptoms, as suggested by Kroenke. The diagnosis of undifferentiated somatoform disorder, requiring only 1 unexplained symptom, was obtained by 94 of the subjects. CONCLUSION: Findings from this study revealed widely divergent prevalence rates of somatoform disorders, depending on methods of diagnosis used. Correlation with rates of medical utilization is suggested as an external criterion for validating diagnostic methods.

The somatizing patient

Somatization is the experience of physical symptoms in response to emotional distress. It is common, costly, and frustrating to both the patient and physician. Successful treatment of somatization requires the physician to pursue a positive diagnosis rather than rely on a diagnosis of exclusion. Treatment consists of giving an acceptable explanation of the symptoms to the patient, avoiding unwarranted interventions, and arranging brief but regular office visits for which the patient does not need to develop a new symptom to receive medical attention.

Health care reform: implications for academic psychiatric institutions

Health care reform provides an opportunity to redefine all aspects of our health care delivery system. This article focuses on mental health services and on the implications of health care reform for academic psychiatric institutions. Questions are raised regarding the challenges that academic psychiatric centers will face in pursuing the traditional responsibilities of research, education, and clinical care. The authors propose that intersystems dialogue will create solutions to the questions. The challenge to academic psychiatric institutions rests in creating the dialogue that will inform and guide new decisions regarding research, education, and clinical priorities with the ultimate aim of ensuring that quality is preserved through reform.

Mental health/medical care cost offsets: opportunities for managed care

Health services researchers have long observed that outpatient mental health treatment sometimes leads to a reduction in unnecessary or excessive general medical care expenditures. Such reductions, or cost offsets, have been found following mental health treatment of distressed elderly medical inpatients, some patients as they develop major medical illnesses, primary care outpatients with multiple unexplained somatic complaints, and nonelderly adults with alcoholism. In this paper we argue that managed care has an opportunity to capture these medical care cost savings by training utilization managers to make mental health services more accessible to patients whose excessive use of medical care is related to psychological factors. For financial reasons, such policies are most likely to develop within health care plans that integrate the financing and management of mental health and medical/surgical benefits.

Management of somatisers in primary care: are family doctors motivated?

OBJECTIVE

The aim of this paper is to assess the attitudes of Spanish general practitioners towards somatisers and the degree of involvement that family doctors are ready to adopt in the care of these patients.

METHOD

A postal questionnaire on attitudes was sent to a representative sample (n = 135) of general practitioners from two health districts of the region of Aragon. Seventy (51.8%) of them returned usable questionnaires.

RESULTS

Most of the general practitioners were interested in the treatment of somatisers and considered that they should be treated at primary care level. However, when specific treatment tasks were proposed, they only accepted to act as a filter to specialised care and to care for patients with chronic functional syndromes. Additionally, they refuse to detect presenting somatisers, to prescribe psychotropic drugs or offer any psychological approach, and to avoid reinforcing abnormal illness behaviour in these patients and their families. These findings can be explained because the main emotions somatisers produce in doctors are frustration and anger.

CONCLUSIONS

Family doctors need a lot more help, education and support in the management of somatisers, and psychiatrists need to provide it. Any management program for the treatment of somatisers in primary care should include methods to modify general practitioners' attitudes towards these patients.

Reassurance therapy: what to say to symptomatic patients with benign or non-existent medical disease

Reassurance is one of the most important therapies that primary care physicians give; however, little has been written about it in the literature. This article suggests six steps needed for effective reassurance in patients with benign disease or symptoms not explained by disease. These include; 1) question and examine the patient, 2) assure the patient that serious illness is not present, 3) suggest the symptom will resolve, 4) tell the patient to return to normal activity, 5) consider non-specific treatment, and 6) follow the patient Only if these systematic steps are followed will reassurance consistently work. Since examination of the patient is a critical component of reassurance therapy, it can most effectively be administered by individuals who include a physical assessment as a part of the clinical evaluation.

A symptom checklist to screen for somatoform disorders in primary care

Current DSM-IV somatoform diagnoses may inadequately capture many somatizing patients in primary care. By using data from two studies (1,000 and 258 patients, respectively), the authors determined 1) the optimal threshold on a checklist of 15 physical symptoms to screen for a recently proposed somatoform diagnosis, multisomatoform disorder (MSD), and 2) the concordance between MSD and somatization disorder. The optimal threshold for pursuing a diagnosis of MSD was seven or more physical symptoms. The majority (88%) of the patients who met criteria for MSD had either full or abridged somatization disorder. MSD was intermediate between abridged and full somatization disorder in terms of its association with functional impairment, psychiatric comorbidity, family dysfunction, and health care utilization and charges.

The value of screening for psychiatric disorders prior to upper endoscopy

Gastrointestinal (GI) complaints are among the most common symptoms in primary care yet are frequently unexplained and often lead to costly diagnostic testing. We sought to determine the prevalence of psychiatric disorders in patients with unexplained GI complaints undergoing upper endoscopy, and the likelihood of endoscopic abnormalities in patients with and without psychiatric diagnoses. We prospectively evaluated 116 adult patients who were undergoing upper endoscopy to evaluate GI complaints. All subjects received a structured psychiatric interview prior to endoscopy using PRIME-MD, and endoscopists were blinded to the PRIME-MD results. Psychiatric disorders were detected in 70 (60%) patients. Overall, there were 113 diagnoses (some patients had multiple disorders) with the most common being somatoform (44%), depressive (29%), and anxiety (19%) disorders. Only 29 patients had major endoscopic abnormalities, including esophageal disease (14), peptic ulcer (9), severe gastritis (4), gastric cancer (1), and esophageal cancer (1). There was a much higher prevalence of psychiatric disorders in patients without major endoscopic abnormalities (74% vs. 21%, p < 0.0001). Psychiatric disease was strongly predictive of endoscopic findings (OR for major abnormality = 0.11 in women, and 0.40 in men), especially if somatoform disorder was present (OR = 0.15). We conclude that, with a simple questionnaire, psychiatric disorders can be diagnosed in a large proportion of patients with unexplained GI complaints who are referred for upper endoscopy. The presence of a psychiatric disorder, particularly if somatoform, makes it unlikely that endoscopy will reveal significant GI disease.

Services utilization before and after the prospective payment system by patients with somatization disorder

This study analyzed services utilization before and after the implementation of Medicare's Prospective Payment System (PPS) in psychiatric patients with somatization disorder in two samples: one recruited before the PPS and the other after the PPS. Individuals with this psychiatric disorder present with multiple unexplained medical complaints and consume a great number of health resources. The results from this study indicated that Medicare PPS was associated with fewer hospital admissions and fewer hospital days, with a greater number of physician visits (for Medicare patients) and emergency room visits (for non-Medicare patients) and with lower overall health expenditures. However, there were no significant changes in the average length of stay after PPS. In contrast to previous studies, Medicare PPS was significantly associated with changes in service utilization by non-Medicare patients as well, a possible "spillover effect." This study confirms the results from other research indicating that higher levels of efficiency may be achieved for certain psychiatric disorders through prospective payment mechanisms.

Group therapy for somatization disorders in general practice: effectiveness of a short cognitive-behavioural treatment model

The objective of this study was to evaluate the effect of a short cognitive behavioural group therapy programme for somatization disorder in primary care. The treatment model was focused on patient education and stress relaxation. A controlled and prospective study design was used with repeated assessments of the patients' perception of their psychosocial problems, psychological distress and medication usage. The results were analysed up to 6 months after treatment and showed the treated patients to be moderately but significantly improved with respect to physical illness and somatic preoccupation, hypochondriasis, and medication usage. In a control group of untreated patients no such improvements were observed. In summary, the short group treatment programme used in this study may be beneficial for patients with somatization disorders. With some modifications it might be useful to practitioners in primary care for the management of psychosomatic disorders.

Somatoform disorders in Caucasian and Chinese Americans

Somatization, broadly defined as the presentation of one or more medically unexplained somatic symptoms, refers both to the presentation of somatic symptoms in diagnosable psychiatric disorders such as major depression or anxiety as well as to the presentation of such symptoms in somatoform disorders. Although no comparative data exist, somatization is considered by many clinical investigators to be more common among Chinese than Caucasian patients, but it is unclear if this occurs because somatoform disorders are more prevalent among the Chinese or because Chinese patients with major depression or anxiety more often present with somatic complaints. We examined 85 consecutive Chinese American and 85 consecutive Caucasian American patients referred for psychiatric consultation and found the following: a) True somatization was significantly more common among Chinese American patients referred for psychiatric consultation; b) The somatoform symptom profiles of the two cohorts were different: Chinese American somatizers complained predominantly of cardiopulmonary and vestibular symptoms, whereas their Caucasian counterparts had symptoms that corresponded well with the categories listed in DSM-IV; c) In both cohorts of somatizers, a concurrent psychiatric disorder, most commonly major depression, was almost always present; and d) Among the Chinese American somatizers, pseudoneurological symptoms occurred most commonly in the form of abnormal sensations, whereas abnormal motor functions were more common among Caucasian Americans. Implications of the findings with respect to pathogenesis, treatment, and classification of somatization are discussed.

Effects of nortriptyline on depression and glycemic control in diabetes: results of a double-blind, placebo-controlled trial

OBJECTIVE

Depression is a prevalent and chronic condition in diabetes and is associated with poor glucose regulation and poor compliance with diabetes treatment. This investigation evaluated the effects of nortriptyline on depression and glycemic control to see whether depression in diabetes is treatable and whether restoring mental health contributes to improved medical outcome.

METHOD

Sixty-eight diabetic patients with poor glycemic control, 28 of whom had active major depression (DSM-IIIR), completed a randomized, placebo-controlled, double-blind trial involving 8 weeks of treatment with nortriptyline targeted to therapeutic plasma levels (50-150 ng/ml). Depression improvement was determined with the Beck Depression Inventory; glucose control was measured by glycated hemoglobin levels. Compliance behavior was assessed using medication dispensing devices and glucometers equipped with electronic memory.

RESULTS

The reduction in depression symptoms was significantly greater in depressed patients treated with nortriptyline compared with those receiving placebo (-10.2 vs -5.8, p = .03). Nortriptyline was not statistically superior to placebo in reducing glycated hemoglobin of the depressed subjects (p = .5). However, path analysis indicated that the direct effect of nortriptyline was to worsen glycemic control whereas depression improvement had an independent beneficial effect on glycated hemoglobin. These findings were not explained by the relationships of nortriptyline treatment to weight change (r = -0.21, p = .31) or depression improvement to compliance with the protocol for self-monitoring of blood glucose (r = 0.01, p = .97).

CONCLUSIONS

Major depression in diabetic patients can be effectively treated with nortriptyline at the expense of a direct hyperglycemic effect. Path analysis demonstrated a treatment-independent effect of depression improvement on glycemic control, suggesting that a more ideal antidepressant agent may both restore mental health and improve medical outcome.

Chronic fatigue syndrome. A practical guide to assessment and management

Chronic fatigue and chronic fatigue syndrome (CFS) have become increasingly recognized as a common clinical problem, yet one that physicians often find difficult to manage. In this review we suggest a practical, pragmatic, evidence-based approach to the assessment and initial management of the patient whose presentation suggests this diagnosis. The basic principles are simple and for each aspect of management we point out both potential pitfalls and strategies to overcome them. The first, and most important task is to develop mutual trust and collaboration. The second is to complete an adequate assessment, the aim of which is either to make a diagnosis of CFS or to identify an alternative cause for the patient's symptoms. The history is most important and should include a detailed account of the symptoms, the associated disability, the choice of coping strategies, and importantly, the patient's own understanding of his/her illness. The assessment of possible comorbid psychiatric disorders such as depression or anxiety is mandatory. When the physician is satisfied that no alternative physical or psychiatric disorder can be found to explain symptoms, we suggest that a firm and positive diagnosis of CFS be made. The treatment of CFS requires that the patient is given a positive explanation of the cause of his symptoms, emphasizing the distinction among factors that may have predisposed them to develop the illness (lifestyle, work stress, personality), triggered the illness (viral infection, life events) and perpetuated the illness (cerebral dysfunction, sleep disorder, depression, inconsistent activity, and misunderstanding of the illness and fear of making it worse). Interventions are then aimed to overcoming these illness-perpetuating factors. The role of antidepressants remains uncertain but may be tried on a pragmatic basis. Other medications should be avoided. The only treatment strategies of proven efficacy are cognitive behavioral ones. The most important starting point is to promote a consistent pattern of activity, rest, and sleep, followed by a gradual return to normal activity; ongoing review of any 'catastrophic' misinterpretation of symptoms and the problem solving of current life difficulties. We regard chronic fatigue syndrome as important not only because it represents potentially treatable disability and suffering but also because it provides an example for the positive management of medically unexplained illness in general.

Nonpsychotic thought disorder: objective clinical identification of somatization and antisocial personality in language patterns

This report describes a new method of using language patterns to identify somatization and antisocial personality (ASPD) disorders in clinical practice. A set of definitions describing characteristic speech patterns was developed to identify "nonpsychotic thought disorder" (NPTD). Speech patterns of subjects with somatization disorder and/or ASPD were compared with those of controls. Blind raters assessed audiotaped samples of speech obtained through open-ended interviews for instances of elements of NPTD. Women with somatization or ASPD had significantly more NPTD speech responses than controls, and women with both disorders showed the greatest amount. Antisocial men did not demonstrate more NPTD than controls, nor was somatization in men associated with NPTD. Clinical attention to speech patterns in patients may help alert clinicians to these disorders in women and serve as indicators for screening for these disorders. More study is needed to develop psychometric properties of the instruments on larger samples, and to identify speech indicators of personality disorder in men. It is likely that other personality disorders, e.g., borderline personality disorder, can be identified through speech patterns, and they deserve study with these methods.

Using successful models of care to guide the teaching of psychiatry in primary care

The focus of efforts to improve primary care physicians' recognition and treatment of psychiatric conditions has been on enhancing the content of their education, with little attention paid to the choice of models through which the content is delivered. The authors believe that existing models of primary care delivery are analogous to Strain's six basic models of teaching psychiatry to primary care physicians. Each model is especially suited to a particular segment of the primary care physician's education; for example, the consultation model has relevance for teaching about better management of identified patients and the bridge model for enhancing recognition of unrecognized disorders. All six models have a place in both education and practice.

Frequent attender profiles: different clinical subgroups among frequent attender patients in primary care

Psychiatric and physical morbidity among frequently attending patients in primary care is high. However, very few efforts have been made to sort out the complex patterns of problems these patients have. We developed a clinical grouping of these patients. Our sample consisted of 67 frequent attenders. The measures included physical and psychiatric illnesses, presenting symptoms, sociodemographic data, psychosocial situation, level of distress, global functioning, experienced life satisfaction, illness attribution, and current psychiatric treatment. We identified five groups with different profiles: (1) patients with entirely physical illnesses; (2) patients with clear psychiatric illnesses; (3) crisis patients; (4) chronically somatizing patients; and (5) patients with multiple problems. The grouping was based on multidimensional operational criteria. The majority in all groups attended for solely physical illnesses or symptoms suggesting different forms of somatization. Only a few patients were undergoing any psychiatric treatment. Differences between groups were found regarding sociodemographic factors, physical illnesses, global functioning, and satisfaction.

Psychiatry in medical practice. Implications for the education of primary care physicians in the era of managed care: Part 2

In Part 1 of this 2-part series, the epidemiology of psychiatric disorders in primary care settings was reviewed as well as evidence that indicates that these conditions often go underrecognized and undertreated by primary care physicians. Educational studies to improve the psychiatric skills of primary care physicians were also reviewed. In Part 2 of this series, a core curriculum for primary care physicians in the diagnosis and treatment of psychiatric disorders that emphasizes competency-based learning is presented. Recommendations for the development and implementation of these competency-based training modules are offered in the conclusion.

Psychiatry in medical practice. Implications for the education of primary care physicians in the era of managed care: Part 1

In an effort to control the costs of mental health care, many medical care systems have emphasized the management of psychiatric illness by primary care physicians and curtailed specialty mental health referrals. While this trend mandates that primary care physicians have expertise in the diagnosis and treatment of psychiatric disorders, evidence indicates that not only are psychiatric disorders underrecognized in primary care settings, but also that treatment is often inadequate and accompanied by less than optimal outcomes. In Part 1 of this 2-part series, representative studies of the epidemiology of psychiatric disorders in primary care are reviewed in addition to data that has documented low rates of recognition and suboptimal management of psychiatric illness. In Part 2, to be published in the January-February 1997 issue of Psychosomatics, a core psychiatric curriculum for primary care physicians will be presented that emphasizes the use of competency-based training modules. Strategies for the development and implementation of these educational training modules will also be discussed.

Supervised integrated screening of low-back pain patients by a neurologist. A randomized clinical trial

In a randomized, controlled design, the effect of psychiatric consultation intervention in medical outpatients with low-back pain (N = 104) was assessed for the patients' subjective well-being and satisfaction of general practitioners (GPs) in their cooperation with the neurologists. The goal of the intervention was an integrated approach towards the patients' symptoms and the improvement of the cooperation between primary and secondary medical health services. The intervention was designed at the health care provider level; the psychiatrist did not see or examine the patient. The 104 patients were subdivided into an intervention group (N = 50) and a control group (N = 54). The major outcome measures were the psychological status of the patient and degree of the GPs' satisfaction concerning the cooperation with the medical specialists. After 6 months follow-up, there was a greater overall decline of symptoms in the patient intervention group compared with the control group. However, it was not possible to specify this effect. Contrary to the hypotheses, GPs in the control group were as satisfied about the cooperation with the neurologist as their colleagues in the intervention group. Yet, the information in the specialists' letters of the intervention group was more often in agreement with the integrated model carried out. It is concluded that great diversity of the target group of patients and the focus on the neurologists' behavior may explain the lack of hypothesized effects. It is recommended that the target group be more specifically defined, and that a more intensive intervention might prove to be more effective.

Psychiatric interventions in the medically ill. Outcome and effectiveness research

This article reviews the current status and emerging trends of outcome data from research studies of psychiatric and psychosocial interventions for mental disorders in patients in the general medical sector. Although data from such studies have had limited success to date in influencing health policy, legislators and administrators are increasingly likely to turn to outcome data to inform their decisions. The impact of psychiatric disorders, the recognition and treatment or referral of psychiatric-disordered patients by general medical practitioners, and the outcome results of psychiatric intervention programs are examined for both the inpatient and outpatient general medical sectors.

Screening for somatizing patients in the pulmonary subspecialty clinic

Somatizing patients present a history of vague, unexplained medical symptoms. This study compared somatizing patients with pulmonary control subjects by using the Diagnostic Interview Schedule (DIS-III-R), the Illness Attitude Scales (IAS), and the Minnesota Multiphasic Personality Inventory (MMPI-2). The groups differed in the number of somatization symptoms reported and in the frequency of somatization disorder diagnoses when the screening criteria were used. The somatizing group obtained higher scores on the bodily preoccupation and hypochondriacal beliefs subscales of the IAS; no differences were found on the MMPI-2. These findings indicate that the DSM-III-R somatization screening items can be useful for detecting somatization when patients present with unexplained respiratory complaints.

Consultation-liaison psychiatry and the practice of medicine. The Thomas P. Hackett Award lecture given at the 42nd annual meeting of the Academy of Psychosomatic Medicine, 1995

The contributions of consultation-liaison psychiatrists have significantly influenced the practice of medicine. The author reviews the pertinent literature that substantiates this observation as well as suggests areas that hold promise for such contributions in the future.

Clinical practice issues in consultation-liaison psychiatry

OBJECTIVE

To overview and highlight the issues currently challenging and confronting consultation-liaison (C-L) psychiatry and to present them for discussion in a wider forum.

METHOD

Following preliminary discussions, the authors (members of the New South Wales C-L Interest Group) undertook to selectively review a number of issues relevant to C-L psychiatry. A preliminary paper was prepared and then presented to the membership of the interest group. Feedback from this meeting was incorporated into the final version of the paper.

RESULTS

Issues selected as a nidus for further discussion include economic issues, changing models of C-L practice, service issues as well as ethical, issues. In addition, recognition of C-L psychiatry as a true subspeciality is foreshadowed.

CONCLUSION

This paper highlights some of the challenges for C-L psychiatry both now and in the future. Intuitive beliefs in our efficacy will not suffice in this era of economic rationalisation. Disciplined and focused research substantiating our value is imperative. Subspeciality recognition is likely to ensure uniformity of standards as well as providing the structure and direction required to consolidate C-L psychiatry's future.

Psychiatric consultation for somatizing patients in the family practice setting: a feasibility study

OBJECTIVE

The purpose of the study was to assess the feasibility of a psychiatric consultation intervention for somatizing patients in the family practice setting in terms of 1) patient compliance, 2) patient satisfaction, and 3) compliance and satisfaction of general practitioners (GPs).

METHOD

In a period of nine months, forty-six patients were selected for psychiatric consultation in six solo family practices in a semi-urban area in the Netherlands. The consultation included an interview with the consulting psychiatrist, the patient, and the GP. A written summary of the consultation was provided to the GP and the patient. A booster session with a GP and psychiatrist was included to evaluate and reinforce the recommendations.

RESULTS

The majority of the selected patients agreed to participate after informed consent. An intervention was implemented containing interpersonal techniques, reattribution, clarification, and structuring. GP compliance with recommendations was 100 percent, patient compliance 75 percent.

CONCLUSION

A standardized psychiatric consultation for somatizing patients in a family practice setting can be implemented. Several levels of implementation can be distinguished.

Psychiatry and primary care as neighbors: from the Promethean primary care physician to multidisciplinary clinic

OBJECTIVE

A successful eight-year experience developing a co-practice model for psychiatry in a primary care practice is described.

METHODS

The effect on service delivery of specific changes in availability, shared location, and consistency of interdisciplinary relationships are discussed.

RESULTS

The following components of successful collaboration were identified: 1) The importance of fiscal organization and leadership factors in creating a successful bridge between psychiatry and primary care. 2) How individual tailoring for the setting (rural vs. urban) affects the collaboration. 3) Adaptations incumbent upon psychiatrists to function well in such settings. 4) The development of a teaching program and training track for medical and psychiatric housestaff in such settings.

CONCLUSIONS

Making psychiatry accessible at the front line of primary care enhances delivery of care and does not detract from any service.

Enhancing the health of somatization disorder patients. Effectiveness of short-term group therapy

To identify an effective method of treating patients with somatization disorder (SD), the authors conducted a randomized controlled clinical trial of group therapy with 70 SD patients. Primary care physicians treating all patients in the study received a consultation letter offering treatment recommendations for SD. The experimental patients were invited to attend eight group therapy sessions in addition to the consultation provided to their physicians; 45% attended one or more sessions. The experimental patients reported significantly better physical (P < 0.05) and mental (P < 0.01) health in a 1-year period during and after group therapy. The more group sessions SD patients attended, the greater the improvement in general and mental health. The 52% net savings in health care charges associated with group therapy plus the consultation indicate that it is economically feasible to improve outcomes without escalating the cost of care in this group of high users of medical resources.
