Detecting symptoms of alcohol abuse in primary care settings.

BACKGROUND: Studies on alcohol abuse are frequently based on patients who meet minimum diagnostic criteria, thus ignoring patients with individual symptoms of harmful or hazardous use. Consequently, we are unable to characterize alcohol-abusing patients with sufficient clarity to effectively focus screening for primary prevention. OBJECTIVE: To determine the prevalence of harmful and hazardous use of alcohol, assess screening instruments for detecting alcohol abuse or dependence, and assess the impact of alcohol use on other diagnoses treated in outpatient settings. DESIGN: Survey (cross-sectional study). SETTING: Hospital-based outpatient clinic. PARTICIPANTS: Three hundred randomly selected adults (aged 18 years and older). MAIN OUTCOME MEASURE: Diagnosis of alcohol abuse or dependence based on the Diagnostic Interview Schedule (DIS). RESULTS: About 18% met DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) criteria of abuse or dependence while almost 50% had at least one symptom of harmful or hazardous use. The T-ACE questionnaire, a modified version of the CAGE questionnaire, was the most effective screening instrument for both men and women. Selected diagnoses, personal characteristics such as family history of alcohol abuse, and self-reported patterns of alcohol use could identify patients likely to meet diagnostic criteria. CONCLUSIONS: Many symptoms of substance use disorders are not adequately addressed in outpatient practice. Little is known about how alcohol use in varying quantities affects health care utilization and treatment of conditions commonly seen in outpatient medicine. Consequently, we lack a full appreciation of the burden of disease borne by alcohol use and have yet to achieve a universally accepted method of approaching primary and secondary prevention of alcohol-related problems.

Encopresis treatment outcome: long-term follow-up of 45 cases.

Among children diagnosed and treated for encopresis (N = 88) at either of two incontinence clinics between 1986 and 1994, 45 could be assessed for long-term (>12 months) outcome. Measures consisted of retrospective analysis of clinical charts and parent report of child soiling status. At follow-up (mean duration 53 months, range 15 to 99 months), 26 children (58%) were in remission, 13 (29%) were improved, and six (13%) showed no improvement. Logistic regression showed that children who presented with no previous encopresis treatment(s) (odds ratio 5.88, 95% confidence interval 1.61 to 21.55, p < .01) and/or children who presented with fecal retention (odds ratio 17.8, 95% confidence interval 2.70 to 153.37, p < .01) were more likely to be in remission. The interval between treatment and follow-up was significantly longer (mean 62 months, range 26 to 94) for children in remission than for children still soiling (mean 45 months, range 15 to 75) (p < .01). At follow-up 1 year or more after treatment for encopresis, a significant number of children may continue to soil. Previous encopresis treatment(s) and/or nonretentive encopresis may be risk factors for persistent soiling. The chances of complete remission of encopresis tend to increase with the passage of time.

The effect of high-dose ascorbate supplementation on plasma lipoprotein(a) levels in patients with premature coronary heart disease.

STUDY OBJECTIVE: To determine the efficacy of high-dose ascorbate supplementation in lowering lipoprotein(a) [Lp(a)] levels in patients with premature coronary heart disease (CHD). DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Outpatient clinic. PATIENTS: Forty-four patients with documented premature CHD, defined as confirmed myocardial infarction and/or angiographically determined stenosis of 50% or greater in at least one major coronary artery before age 60 years. INTERVENTIONS: Patients were block randomized on the basis of age, gender, and screening Lp(a) concentrations to receive ascorbate 4.5 g/day or placebo for 12 weeks. MEASUREMENTS AND MAIN RESULTS: High-dose ascorbate was well tolerated and produced a marked elevation in mean plasma ascorbate levels (+1.2 mg/dl; p < 0.001). Multiple linear regression analysis revealed no significant effect of supplementation on postintervention Lp(a) levels (p = 0.39) in a model that included treatment group assignment, and baseline Lp(a) levels. CONCLUSIONS: Our findings do not support a clinically important lowering effect of high-dose ascorbate on plasma Lp(a) in patients with premature CHD.

The plain abdominal roentgenogram in the management of encopresis.

OBJECTIVE: To determine whether fecal retention in encopretic children can be assessed objectively using the plain abdominal roentgenogram and whether roentgenographic evidence of fecal retention is associated with clinical findings on presentation in encopretic children. DESIGN: Retrospective case studies. SETTING: Two pediatric incontinence clinics. PARTICIPANTS: Sixty children (72% male), aged 4 to 18 years (mean, 8 years), who met Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition criteria for the diagnosis of encopresis. All had a plain abdominal roentgenogram obtained on presentation. INTERVENTIONS: None. RESULTS: Using a systematic assessment tool with good interrater reliability (kappa = 0.65), 78% (47) of the children had fecal retention by roentgenographic criteria on presentation, while 22% (13) did not. Retentive encopretic children were less likely to have a history of difficult toilet training (P = .018) than nonretentive encopretic children. There was no association between fecal retention and several clinical factors, including historical features commonly attributed to fecal retention. Retentive encopretic children were no more likely to have a palpable abdominal mass than nonretentive encopretic children, but they were more likely to have excessive stool on rectal examination (P = .015). Using the plain abdominal roentgenogram as the gold standard, the rectal examination showed a positive predictive value of 84.8% and a negative predictive value of 50% in assessing fecal retention. CONCLUSIONS: Fecal retention in encopretic children can be assessed objectively from a plain abdominal roentgenogram. Most, but not all, encopretic children present with fecal retention. A positive rectal examination is strongly predictive of fecal retention, in which case a roentgenogram is not necessary to make that diagnosis. A negative rectal examination may not rule out fecal retention, in which case an abdominal roentgenogram may be useful to make that diagnosis.

Comparison of primary care residents' confidence and clinical behavior in treating hypertension versus treating alcoholism.

PURPOSE: To compare the self-reported confidence and clinical behaviors of primary care residents in treating alcoholism versus hypertension. METHOD: Eighty-five residents, 36 in family medicine and 49 in primary care internal medicine, representing all years of the three-year training programs at two hospitals affiliated with the Brown University School of Medicine, were surveyed in 1988. Self-report questionnaires elicited demographic data and several responses (ranged on scales of 1, not confident or frequent, to 10, very confident or frequent) about the residents' confidence and frequency of use of clinical behaviors with both alcoholic and hypertensive patients. Paired t-tests were used to compare the responses about hypertension with those about alcoholism. RESULTS: Questionnaires were completed by 54 (63.5%) of the residents. No significant difference was found between the residents' responses by sex or program, but there was a significant difference (p < .0001) between the responses with regard to the two disorders. The residents had more confidence about their management of hypertension (a mean score of 8.81 versus 7.95 for alcoholism). They also reported greater use of appropriate clinical behaviors with hypertensive patients (mean scores in the very confident range of 7.5 to 8.2 compared with means in the moderate range of 4.9 to 7.1 for alcoholism). CONCLUSION: Both the family medicine and the internal medicine residents were significantly more confident in managing all aspects of hypertension than in managing alcoholism, and they reported significantly greater frequency in utilizing appropriate clinical behaviors for hypertension than for alcoholism.

The provision of physical activity to hospitalized elderly patients.

Physical activity has been recognized as an important aspect of patient care for nearly 50 years. Yet, deconditioning and functional decline of hospitalized elderly patients continue to be reported. Such outcomes suggest that a good system for providing activity in hospitals is lacking. In this retrospective study we assessed the provision of physical activity to 500 elderly patients (100 in each of five hospitals) during the first 7 days of hospitalization. No activity order was in effect on 13% of the 3500 patient days reviewed. When activity was ordered, patient activity was different from the activity permitted by the physician orders on 41% of the days. Patients who remained in bed or in a chair rarely received physical therapy, never had physician orders for exercises, and never performed exercises with the nurses. These findings demonstrate that the current practices for the provision of physical activity in hospitals are ineffective.
