Inpatient standards of care and the suicidal patient. Part I: General clinical formulations and legal considerations.

The most common legal action involving psychiatric care is the failure to reasonably protect patients from harming themselves. In this regard it is critical to understand that courts have tended to impose much stricter standards on inpatient than on outpatient care; that at the present time, most malpractice actions involve clinical activities related to inpatient care (negligent admission, treatment, supervision, discharge, etc.). This article reviews the current climate in the legal and clinical formulation of standards of care for hospitalized adult suicidal patients. It suggests general guidelines for effective assessment, management, and treatment procedures that balance the need for high-quality care by a reasonable and prudent practitioner with the requirements of court-determined and statutory standards. The authors specifically discuss court cases that show common failure situations in inpatient care, discharge planning, and follow-up (e.g., problems in pharmacotherapy, the decision to hospitalize, the assessment of imminence and lethality, etc.). The paper also emphasizes the crucial element of clinical judgment in developing any inpatient standard of care.

Psychiatric morbidity among dermatology inpatients.

BACKGROUND: Research on psychiatric morbidity among patients with dermatological diseases generally focuses on outpatients and questionnaire-based surveys. The aim of this study was to determine the prevalence and nature of psychiatric morbidity among dermatological inpatients with diagnosis being made by psychiatric interview, and ascertain whether demographic and clinical details in dermatological inpatients with psychiatric morbidity differed from those without it. METHODS: Charts of all inpatients admitted by the dermatology department between 1 January 1991 and 31 July 1995 were analysed for socio-demographic data, clinical features, treatment and course in hospital. For those patients who were referred to a psychiatrist, all records of the psychiatric consultation were obtained and analysed. RESULTS: A total of 1073 patients were admitted during the study period. Ninety-eight patients (9%) were diagnosed to have a psychiatric illness. Patients with psychiatric illness were likely to have had more admissions and longer duration of hospital stay. The most common psychiatric diagnoses were depressive episodes (34%) and adjustment disorders (29%). The highest rates of psychiatric morbidity were found among patients with chronic urticaria, exfoliative dermatitis and sexually transmitted diseases, including human immunodeficiency virus infection. The prevalence of psychiatric disorders was significantly higher in those who had received long term (more than six weeks) treatment with high-dose steroids (more than 1 mg/kg body weight of prednisolone). CONCLUSION: Some dermatology inpatients have psychiatric morbidity, which affects the course of the dermatological condition as well as the duration of hospitalization. The availability of psychiatric consultation at dermatology clinics and regular liaison between psychiatrists and dermatologists are essential for appropriate management.

[Physical complaints, stress and quality of life of oncologic patients. Effects and patient assessment in inpatient rehabilitation].

AIM: To what extent do cancer patients use an inpatient aftercare programme and how is its effect been estimated by them? How is the progress of "general physical complaints", "psychosocial stress" and "satisfaction with life" in some cases over a period of up to eight months? PATIENTS AND METHODS: To 201 patients with breast or intestinal cancer respectively, who were going to be or had already been admitted to an inpatient aftercare, standardised and unstandardized questionnaire were presented to be filled out at 4 or 5 different dates before and during the programme as well as 3 and 6 months later. RESULTS: Many patients tried to take part in the aftercare programme actively. Even 6 months later 95.6% estimated it as being "successful" and 70% said that there had been a lasting positive effect after the treatment. The "general physical complaints" and "psychosocial stress" grew significantly less during the inpatient aftercare programme and "satisfaction with life" improved. After the treatment these effects were declining again. CONCLUSIONS: The results indicate that many patients, who participate in an inpatient aftercare programme, profit by it directly. As the positive effects partially get lost during the following months, the patients should be prepared more intensely for the time after dismission with its higher level of strain and should get an especially attentive ambulant care at home.

Glycemic control and sliding scale insulin use in medical inpatients with diabetes mellitus.

OBJECTIVE: To identify predictors of hypoglycemic and hyperglycemic episodes in hospitalized patients with diabetes with special attention to the effectiveness of sliding scale insulin regimens. DESIGN: Prospective cohort study. SETTING: Urban university hospital. PARTICIPANTS: One hundred seventy-one adults with diabetes mellitus as a comorbid condition admitted consecutively to medical inpatient services during a 7-week period. MEASUREMENTS: Demographic, clinical, and laboratory data from inpatient medical records. MAIN OUTCOMES: Rates of hypoglycemic (capillary blood glucose, < or = 3.3 mmol/L [< or = 60 mg/dL]) and hyperglycemic (capillary blood glucose, > or = 16.5 mmol/L [> or = 300 mg/ dL]) episodes. RESULTS: Of the patients, 23% experienced hypoglycemic episodes, and 40% experienced hyperglycemic episodes. The overall rates of hypoglycemic and hyperglycemic episodes were 3.4 and 9.8 per 100 capillary blood glucose measurements, respectively. Independent predictors of hypoglycemic episodes included African American race (relative risk [RR], 2.13) and low serum albumin level (RR, 1.92 per 100-g/L decrease); corticosteroid use was associated with a reduced risk of hypoglycemic episodes (RR, 0.32; P < .05). Independent predictors of hyperglycemic episodes included female gender (RR, 1.67), severity of illness (RR, 1.22 per 10 Acute Physiology and Chronic Health Evaluation III units), severe diabetic complications (RR, 2.32), high admission glucose level (RR, 1.33 per 5.5 mmol/L), admission for infectious disease (RR, 2.14), and corticosteroid use (RR, 3.74; P < .05). Of 171 patients, 130 (76%) were placed on a sliding scale insulin regimen. When used alone, sliding scale insulin regimens were associated with a 3-fold higher risk of hyperglycemic episodes compared with individuals following no pharmacologic regimen (RRs, 2.85 and 3.25, respectively; P < .05). CONCLUSIONS: Suboptimal glycemic control is common in medical inpatients with diabetes mellitus. The risk of suboptimal control is associated with selected demographic and clinical characteristics, which can be ascertained at hospital admission. Although sliding scale insulin regimens are prescribed for the majority of inpatients with diabetes, they appear to provide no benefit; in fact, when used without a standing dose of intermediate-acting insulin, they are associated with an increased rate of hyperglycemic episodes.

Does the computerized display of charges affect inpatient ancillary test utilization?

BACKGROUND: The computerized display of charges for ancillary tests in outpatients has been found to affect physician-ordering behavior, but this issue has not been studied in inpatients. OBJECTIVE: To assess whether the computerized display of charges for clinical laboratory or radiological tests affected physician-ordering behavior. PATIENTS AND METHODS: Two prospective controlled trials, randomized by patient, were performed. Each trial included all medical and surgical inpatients at 1 large teaching hospital during 4 and 7 months: 3536 intervention and 3554 control inpatients in the group with clinical laboratory tests, and 8728 intervention and 8653 control inpatients in the group with radiological tests. The intervention consisted of the computerized display of charges for tests at the time of ordering. MAIN OUTCOME MEASURES: The number of clinical laboratory and radiological tests ordered per admission and the charges for these tests. RESULTS: For the clinical laboratory tests, during a 4-month study period, patients in the intervention group had 4.5% fewer tests ordered, and the total charges for these tests were 4.2% lower, although neither difference was statistically significant. Compared with historical controls from the same 4-month period a year before, the charges for the tests per admission had decreased 13.3%, but the decrease was temporally correlated with a restriction of future ordering of tests, and not with the introduction of the display of charges. For the radiological tests, during a 7-month period, the intervention group had almost identical numbers of tests ordered and charges for these tests. CONCLUSIONS: The computerized display of charges had no statistically significant effect on the number of clinical laboratory tests or radiological procedures ordered or performed, although small trends were present for clinical laboratory tests. More intensive interventions may be needed to affect physician test utilization.

Hospitalization, inpatient physical therapy and institutionalization after hospital discharge of prostate cancer patients in south Florida.

PURPOSE: Explaining survival variation in prostate cancer requires the identification of new predictive factors, of which physical function is attractive hypothetically. To understand physical dysfunction in prostate cancer better, we examined medical claims. Our aims were to describe the consumption of inpatient resources, examine the association of physical therapy with institutionalization after hospital discharge and determine the association of disease stage with frequency of hospitalization, inpatient physical therapy and discharge to a skilled nursing facility. MATERIALS AND METHODS: We used 1994 Medicare claims for patients in South Florida who had prostate cancer. To examine the association of disease stage with use of health services, we inferred disease stage from stage specific treatment. Multiple linear regression was used to examine the interaction of inferred disease stage with health services while adjusting for age. RESULTS: A total of 22,279 residents of South Florida a mean of 78.3 years old with prostate cancer billed Medicare in 1994. Of these patients 2,507 were admitted to a hospital 4,606 times, resulting in total charges of $70 million. Many claims indicated physical dysfunction, including 1,896 charges for physical therapy, which was associated with more institutionalization after hospital discharge. Disease stage and patient age were individually associated with the frequency of hospitalization, inpatient physical therapy and discharge to a skilled nursing facility. CONCLUSIONS: Inpatients with prostate cancer have substantial stage dependent physical dysfunction. If the hypothesized interaction of physical dysfunction with mortality is confirmed in prospective studies and outpatient settings, theoretically the door will have been opened to new interventions for prolonging survival in patients with prostate cancer.

[Effectiveness of partial inpatient rehabilitation from the patient's viewpoint. Results of an evaluation of a partial hospitalization model project at the Ichenhausen specialty clinic].

Partial-hospitalization rehabilitation is a relatively recent form of rehabilitation, which, as opposed to the ambulatory approach, comprises the entire programme available for inpatient medical rehabilitation except for accommodation and full board. Great expectations are attached to partial hospitalization: it is supposed to cost less than a comparable in-patient measure but matching in terms of quality. However, hardly any empirical data exist so far concerning the effects partial hospitalization rehabilitation is having in these respects. The present article seeks to answer the question of whether from a patient perspective, the outcome quality of this new model is comparable to that of the classical full-hospitalization programmes. In terms of methodology, questionnaires were used to raise the necessary data from two independent samples (i.e., partial vs. full hospitalization) of former orthopaedic rehabilitees of Fachklinik Ichenhausen (Bavaria). Data analysis included some 205 patient questionnaires (57% return rate). High agreement was found among the two groups concerning outcome evaluation, subjective health and patient satisfaction. From a patient perspective, rehabilitation outcome on the majority of variables considered, even is judged slightly better for partial hospitalization patients than for the inpatient comparison group. As none of these results reach statistical significance, these minor differences should however not be overrated. While partial-hospitalization, rehabilitation, hence, has turned out an option which matches traditional full-hospitalization programmes in terms of quality, too great expectations nevertheless are unwarranted: Partial-hospitalization rehabilitation is no general alternative to inpatient programmes as it will realistically be suitable for a small percentage of orthopaedic patients only, hence be unable to replace full-hospitalization programmes to any major extent. Undoubtedly, however, it is apt to contribute to greater flexibility and needs orientation among the services and programmes available in rehabilitation, and may thus be considered a valuable approach for complementing inpatient and ambulatory forms of rehabilitation.

[Variability of inpatient child and adolescent psychiatry--results of a multicenter documentation].

OBJECTIVE: For the first time in the German-speaking countries a complete evaluation of all 1236 inpatient treatment episodes within one year of investigation was carried out. METHOD: Case-related patient documentation at all of the 13 clinics for child and adolescent psychiatry in Lower Saxony and Bremen were evaluated. RESULTS: Data from all clinics agreed widely on the following: 1. the divergent family structures of the young patients compared to those of the general public, 2. a high degree of individual psychotherapy, and 3. the inclusion of the patient's social circumstances in the individual psychotherapy. Nonetheless, results for most of the variables assessed differed strongly. Inpatient child and adolescent psychiatric care thus seems to vary highly among clinics within the same epidemiological area. CONCLUSIONS: Hence, even when the reported number of episodes is high, no general conclusions on inpatient child and juvenile psychiatric treatment can be drawn on the basis of admissions data for individual clinics. Interinstitutional comparisons must be made on the assumption that there is no prototype clinic for child and adolescent psychiatry. Additional general conclusions include the lack of a disorder-specific approach to treatment. The entry of a large number of patients into foster or state homes following inpatient treatment reflects the impact upon them of abnormal psychosocial circumstances, as well as their decreased psychosocial adaption.

Thiamin and riboflavin status of medical inpatients.

Thiamin status was assessed by erythrocyte transketolase activity (ETKA) and thiamin pyrophosphate effect (TPPE) and riboflavin status by erythrocyte glutathione reductase activity (EGRA) and activity coefficient (AC) in 165 medical inpatients in Ramathibodi Hospital. Based on TPPE > 15 per cent, 9 per cent of the medical inpatients had thiamin depletion. Most of them were patients with renal, cardiovascular, hematological and infectious diseases. Based on AC > or = 1.2, 17 per cent of these inpatients had riboflavin depletion. Most of them were patients with pulmonary, cardiovascular and hematological diseases. Only one patient with pulmonary disease had both thiamin and riboflavin depletion. The proportion of thiamin depletion (2/37) in subjects with thiamin supplementation (mean 32.4, median 6, mode 2 md/d) tended to be less than those without (9/98). But, subjects with riboflavin supplementation (mean 3.3, median 4, mode 1 md/d) had the proportion of riboflavin depletion (0/31) significantly (Z-test, p < 0.005) lower than without supplementation (23/104). The data suggested that although the usual dose of vitamin supplementation in medical inpatients is beneficial thiamin depletion can still be present in catabolic patients.

Intravenous Ketamine reduces psychological pain in suicidal inpatients: A secondary analysis of a six-week randomized placebo-controlled trial.

BACKGROUND: Psychological pain has been conceptualized as an unbearable inner experience and a possible precondition for suicidal ideation. No randomized placebo-controlled study has specifically investigated psychological pain as a treatment target in psychiatric populations. We examined ketamine's effect on psychological pain in suicidal psychiatric inpatients. METHODS: This secondary analysis used KETIS, a 6-week randomized, double-blind, placebo-controlled trial. Participants received two 40-minute intravenous infusions of ketamine (0.5&#xa0;mg/kg) or placebo (0.9% saline) 24&#xa0;h apart, alongside usual care and medication. Psychological and physical pain were assessed at baseline, repeatedly during 96&#xa0;h, and at weeks 2, 4, and 6 using the self-rated PPP-VAS. Longitudinal mixed models compared pain trajectories. RESULTS: The trial randomized suicidal inpatients to ketamine (n&#xa0;=&#xa0;73) or placebo (n&#xa0;=&#xa0;83). Psychological pain decreased in both groups but was lower with ketamine during the first 96&#xa0;h. Pointwise scores were lower with ketamine from 40&#xa0;min to 96&#xa0;h, largest at 40&#xa0;min, 2&#xa0;h, 4&#xa0;h, and 24&#xa0;h (all p&#xa0;<&#xa0;0.001), but not at weeks 2, 4, or 6. This early difference remained significant after adjustment for depressive symptoms and hopelessness. The early reduction appeared more pronounced in the bipolar subgroup. No robust baseline predictors of outcome were identified. CONCLUSIONS: Intravenous ketamine was associated with a greater reduction in psychological pain than placebo in suicidal inpatients, with the clearest effects emerging within the first hours after treatment and remaining evident through the first 96&#xa0;h. Ketamine may represent a clinically relevant option as a psychological pain reliever in psychiatric patients.

Clinical pharmacists and inpatient medical care: a systematic review.

BACKGROUND: The role of clinical pharmacists in the care of hospitalized patients has evolved over time, with increased emphasis on collaborative care and patient interaction. The purpose of this review was to evaluate the published literature on the effects of interventions by clinical pharmacists on processes and outcomes of care in hospitalized adults. METHODS: Peer-reviewed, English-language articles were identified from January 1, 1985, through April 30, 2005. Three independent assessors evaluated 343 citations. Inpatient pharmacist interventions were selected if they included a control group and objective patient-specific health outcomes; type of intervention, study design, and outcomes such as adverse drug events, medication appropriateness, and resource use were abstracted. RESULTS: Thirty-six studies met inclusion criteria, including 10 evaluating pharmacists' participation on rounds, 11 medication reconciliation studies, and 15 on drug-specific pharmacist services. Adverse drug events, adverse drug reactions, or medication errors were reduced in 7 of 12 trials that included these outcomes. Medication adherence, knowledge, and appropriateness improved in 7 of 11 studies, while there was shortened hospital length of stay in 9 of 17 trials. No intervention led to worse clinical outcomes and only 1 reported higher health care use. Improvements in both inpatient and outpatient outcome measurements were observed. CONCLUSIONS: The addition of clinical pharmacist services in the care of inpatients generally resulted in improved care, with no evidence of harm. Interacting with the health care team on patient rounds, interviewing patients, reconciling medications, and providing patient discharge counseling and follow-up all resulted in improved outcomes. Future studies should include multiple sites, larger sample sizes, reproducible interventions, and identification of patient-specific factors that lead to improved outcomes.

House staff team workload and organization effects on patient outcomes in an academic general internal medicine inpatient service.

BACKGROUND: House staff work-hour regulations have required residency programs to reengineer inpatient services. However, few data describe how house staff workload on a patient's day of admission or on subsequent hospital days influences patient outcomes. METHODS: Retrospective cohort analysis of 5742 adults admitted to an academic general medical service between July 1, 1998, and June 30, 2001. RESULTS: After multivariate risk adjustment for patient severity and other structural factors, we found that 2 different measures of house staff workload significantly affected patient outcomes. House staff workload increases on the day of admission, defined as each additional team admission on a patient's admission day, increased length of stay (difference, 3.09%; 95% confidence interval [CI], 2.22%-3.96%), total costs (difference, 2.31%; 95% CI, 1.29%-3.33%), and risk of inpatient mortality (odds ratio, 1.09; 95% CI, 1.02-1.15). Patients had an even higher mortality risk when more than 9 patients were admitted to their team on their admission day. In contrast, house staff workload increases during the patient's entire stay, defined as every additional patient added to the team average census, reduced length of stay (difference, -5.30%; 95% CI, -4.54% to -6.07%) and total costs (difference, -5.11%; 95% CI, -4.20% to -6.00%). Reductions in length of stay and costs were most striking when the team average census exceeded 15 patients. CONCLUSIONS: Our findings suggest that higher house staff workload on admitting days-when fewer backup resources are available-increases resource use and may increase inpatient mortality. Conversely, a higher average team census was associated with reduced resource use, perhaps reflecting service-level adaptations to workload. Future studies should confirm these findings in larger trials.

The predictive utility of a significantly lower WAIS PIQ with psychiatric inpatients.

Contrasted five aspects of psychiatric inpatient care in two psychometrically distinct inpatient samples. The experimental (N = 35) and control groups (N = 35) differed in that the former Ss all scored higher WAIS VIQs than their respective PIQs by at least 15 units. The controls had WAIS VIQs that were within 5 points of their PIQs . Despite this, the two groups were not differentiated according to two other measures of cognitive integrity (Benton, 1963, and Wechsler Memory Scale, Wechsler, 1958); final diagnosis; severity of the S's presentation; capacity to resume self-attorney on discharge, and, finally, prediction of EEG and CT scan result. It was concluded that the poor predictive utility of this form of WAIS analysis did not justify the high cost of WAIS administration in inpatient psychiatric settings.

Interventions to improve antibiotic prescribing practices for hospital inpatients.

BACKGROUND: Up to 50% of antibiotic usage in hospitals is inappropriate. In hospitals infections caused by antibiotic-resistant bacteria are associated with higher mortality, morbidity and prolonged hospital stay compared with infections caused by antibiotic-susceptible bacteria. Clostridium difficile associated diarrhoea (CDAD) is a hospital acquired infection that is caused by antibiotic prescribing. OBJECTIVES: To estimate the effectiveness of professional interventions that alone, or in combination, are effective in promoting prudent antibiotic prescribing to hospital inpatients, to evaluate the impact of these interventions on reducing the incidence of antimicrobial resistant pathogens or CDAD and their impact on clinical outcome. SEARCH STRATEGY: We searched the Cochrane Effective Practice and Organisation of Care (EPOC) specialized register, Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE from 1980 to November 2003. Additional studies were obtained from the bibliographies of retrieved articles SELECTION CRITERIA: We included all randomised and controlled clinical trials (RCT/CCT), controlled before and after studies (CBA) and interrupted time series (ITS) studies of antibiotic prescribing to hospital inpatients. Interventions included any professional or structural interventions as defined by EPOC. DATA COLLECTION AND ANALYSIS: Two reviewers extracted data and assessed quality. MAIN RESULTS: Sixty six studies were included and 51 (77%) showed a significant improvement in at least one outcome. Six interventions only aimed to increase treatment, 57 interventions aimed to decrease treatment and three interventions aimed to both increase and decrease treatment. The intervention target was the decision to prescribe antibiotics (one study), timing of first dose (six studies), the regimen (drug, dosing interval etc, 61 studies) or the duration of treatment (10 studies); 12 studies had more than one target. Of the six interventions that aimed to increase treatment, five reported a significant improvement in drug outcomes and one a significant improvement in clinical outcome. Of the 60 interventions that aimed to decrease treatment 47 reported drug outcomes of which 38 (81%) significantly improved, 16 reported microbiological outcomes of which 12 (75%) significantly improved and nine reported clinical outcomes of which two (22%) significantly deteriorated and 3 (33%) significantly improved. Five studies aimed to reduce CDAD. Three showed a significant reduction in CDAD. Due to differences in study design and duration of follow up it was only possible to perform meta-regression on a few studies. AUTHORS' CONCLUSIONS: The results show that interventions to improve antibiotic prescribing to hospital inpatients are successful, and can reduce antimicrobial resistance or hospital acquired infections.

The impact of inpatient rehabilitation on progressive multiple sclerosis.

One of the primary aims of rehabilitation for patients with multiple sclerosis (MS) is to reduce their levels of disability and handicap, yet little systematic research into the outcomes of this intervention has been undertaken. This stratified, randomized, wait-list controlled study evaluated the effectiveness of a short period of multidisciplinary inpatient rehabilitation in people with MS. Sixty-six patients in the progressive phase of the disease were assessed at 0 and 6 weeks with validated measures of impairment (Expanded Disability Status Scale and Functional Systems), disability (Functional Independence Measure), and handicap (London Handicap Scale). Both groups were comparable in terms of age, sex, disease duration and severity, disability, and handicap. At the end of 6 weeks, although the level of impairment in both groups remained the same, those who participated in a short period of inpatient rehabilitation (average of 25 days) significantly improved their level of disability and handicap compared with those in the wait-list control group. Despite unchanging impairment, inpatient rehabilitation resulted in reduced disability and handicap in patients with progressive MS.

Use of the anxiety control questionnaire in psychiatric inpatients.

We studied the reliability and validity of a measure of perceived control-the Anxiety Control Questionnaire (ACQ)-in a group of psychiatric inpatients. Eighty-nine patients hospitalized on a short-term, university-based psychiatric inpatient unit completed the ACQ, Anxiety Sensitivity Index, Beck Depression Inventory-II, Spielberger State-Trait Anxiety Inventory, MacArthur Admission Experience Survey, and the Lehman Quality of Life Interview. The reliability and validity of the ACQ were consistent with expectations based on prior research with outpatients. Lower levels of perceived control were associated with higher levels of depression and anxiety, lower subjective quality of life, and more perceptions of negative pressure associated with hospital admission. The findings support the potential of the ACQ as a measure of perceived control in psychiatric inpatients. Treatment implications are discussed.

Screening for depression in older medical inpatients.

BACKGROUND: Older people with depression make greater use of healthcare services, but the detection of the disorder is poor. The National Service Framework for Older People recommended screening for depression in acute healthcare settings to improve health outcomes of older people. Previous studies, mainly outside the UK, report widely differing rates for depression that do not usefully inform UK practice. Thus the aim of this study is to estimate, in a large representative sample of older medical inpatients in a UK hospital setting, the prevalence of depressive symptoms and ICD-10 depressive disorder and to examine the sensitivity and specificity of the 15-item Geriatric Depression Scale (GDS-15) as a screening instrument. METHODS: A two-phase prevalence study of depressive disorder was carried out in acute wards of a district general hospital. Six hundred and eighteen (61%) of 1,009 eligible older medical inpatients were screened using the GDS-15. A stratified sample (n = 223) was further assessed using the Geriatric Mental State, from which ICD-10 diagnoses were determined. RESULTS: The weighted prevalence estimate of ICD-10 depressive disorder was 17.7% (95%CI: 12.9-22.5). Forty-four percent of participants scored above the normally recommended cut-point of >or=5 on the GDS-15. However, on the basis of ROC, the optimal cut-point of the GDS-15 for screening for depressive disorder in this hospitalised population is two points higher at >or=7 (sensitivity 0.74, specificity 0.81). CONCLUSIONS: This study confirms that depression is common amongst older UK medical inpatients with 1 in 6 suffering from clinical depression. The cut-point for GDS-15 for this population is >or=7.

Base rates of WAIS-R VIQ-PIQ differences in 1593 psychiatric inpatients.

The purpose of this study was to provide the psychologist with base-rate tables for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal IQ-Performance IQ difference scores in 1593 psychiatric inpatients. Subtables also were provided for each of three primary psychiatric diagnoses (schizophrenia spectrum disorders, bipolar disorders, and depression). The base rates of VIQ-PIQ splits in the full inpatient sample, and those for the subsamples based on primary psychiatric diagnosis, were very similar to those reported in the WAIS-R standardization sample. Consistent with past research on the standardization sample, the VIQ-PIQ split was correlated positively with Full Scale IQ (FSIQ), indicating that larger splits are more common at the higher IQ levels. Therefore, base-rate tables also were provided for the total inpatient sample split into five IQ groupings.
