Persistence of substance use-related hospital utilization among psychiatric consultation patients.

Among 86 consecutive consultation-liaison (C-L) patients with current substance use-related hospital attendance, the case records revealed an average history of 5.9 years in male patients and 5.3 years in female patients of repeated substance use-related hospital visits. A history of at least 1 year was found in 60% (52/86) of patients. The history had started at the age of early 30s with attempted suicide as the most common principal diagnosis. By the age of 40, there had been several hospital visits for various health problems. However, 48% (41/86) of the patients had never received substance use treatment. It appeared that opportunities to intervene with substance use were frequently missed on hospital encounters, a finding also observed in earlier studies.

Patterns of comorbidity in relation to functioning (GAF) among general hospital psychiatric referrals. European Consultation-Liaison Workgroup.

Improvement of services for physically ill patients with concurrent psychiatric problems is a noteworthy issue in general hospitals. Among 1249 general hospital in-patients referred for psychiatric consultation, concurrent mental and behavioural disorders (ICD-10) were diagnosed in 84% of cases. Any concurrent mental and behavioural disorder was associated with dramatically low functioning (GAF = 46), indicating serious psychosocial impairment. This is a striking new finding of clinical importance. The effect on functioning was similar for substance use disorders, other mental disorders, and combined mental and substance use disorders (dual diagnoses), with no gender differences. This finding highlights the need for specialized interventions among general hospital in-patients referred for psychiatric consultation.

Physical and mental comorbidity of substance use disorders in psychiatric consultations. European Consultation-Liaison Workgroup.

Comorbidity of substance use disorders with physical and mental disorders was investigated among 1249 consecutive psychiatric consultation patients admitted to six general hospitals in Finland. Of the patients 354 (28%) were diagnosed with substance use disorders (ICD-10), of which 22% were due to use of at least two different types of psychoactive substances. Alcohol dependence (117/226) in male patients and acute drug intoxication (49/128) at a similar rate as alcohol dependence (44/128) in female patients were the most common clinical conditions. With few exceptions, all substance use disorders were comorbid and in 63% of affected patients comprised a "triple diagnosis" (i.e., physical, mental, and substance use diagnoses concurrently). Poisonings and personality disorders in both sexes, digestive system diseases in men, and injuries in women were related to substance use disorders. Conclusions for service provision were: (1) the high level of co-occurrence of physical and mental disorders with substance use disorders calls for comprehensive, multi-disciplinary assessment of any substance use problems ascertained in psychiatric consultations; (2) poisoning with substance use involvement and mental comorbidity was the most common combined clinical condition justifying provision of addiction psychiatric emergency consultations in general hospitals; (3) polydrug use indicating severe problems and complex treatment needs should be identified; and (4) psychiatric referrals of patients with physical alcohol-related disorders should be ensured in general hospitals.

Psychiatric referrals associated with substance use disorders: prevalence and gender differences. European Consultation-Liaison Workgroup.

A psychoactive substance use disorder (ICD-10) was diagnosed in 28% of 1222 psychiatric referrals in six general hospitals in Finland. In the age group 35 o 50 years, 53% of men and 29% of women had a substance use disorder. In the age group 35 to 50 years, sociodemographic characteristics differentiated men diagnosed with substance use disorders from other male consultation patients, but women with substance use disorders were similar to other female consultation patients. Urgency (i.e., consultation required within the same day) was accentuated in referrals associated with substance use disorders. Of attempted suicides, 65% were related to substance use disorders. Use of sedatives or hypnotics had more frequently induced disorders in women with substance use diagnosis compared to men with diagnosis (30% vs. 13%; p < 0.01). Female consultation patients with substance use disorders more often than respective male patients were current mental health outpatients. In conclusion, the proportion of substance use disorders among psychiatric consultation patients was remarkably higher in the present study (28%) compared with the average provided by the earlier literature (12%), and therefore, at least in Finland, psychiatric assessment of general hospital patients should always include assessment for the presence of substance use disorders. If substance use is only looked for in patients who have social problems typical of advanced misuse, detecting female substance use might be impeded. Relation of attempted suicides to substance use disorders was confirmed. To prevent misuse of prescribed drugs detected particularly in female consultation patients, and to prevent attempted suicides, doctors' attention is called to prescriptions of sedatives and hypnotics.
