Somatic Symptoms in Patients With Cancer Experiencing Pain or Depression

The adverse impact of a high somatic symptom burden is well established for primary care and other noncancer populations with chronic medical disorders. This study examines the impact of somatic symptom burden on disability and health care use in patients with cancer experiencing pain, depression, or both. We performed secondary analyses of baseline data from 405 patients with cancer enrolled in a telecare management trial for pain or depression. Somatic symptom burden was measured using a 22-item scale. Multivariable models were conducted to determine the association of somatic symptom burden with the Sheehan Disability Scale (SDS) score, the number of self-reported disability days in the past 3 months, and health care use. Models were adjusted for sociodemographic characteristics, medical comorbidity, and depression and pain severity. Somatic symptoms were highly prevalent, with 15 of the 22 symptoms reported by more than 50% of patients. The somatic symptom burden was similar across different types and phases of cancer. The mean SDS score (scored 0-10 [not at all disabled to unable to carry out any activities]) was 5.4, and the mean number of self-reported disability days in the past 4 weeks was 16.9. In multivariable models, somatic symptom burden was associated with SDS score (P < .001) and the likelihood of at least 14 disability days in the past 4 weeks (odds ratio, 1.51; 95% confidence interval, 1.19-1.92) but not with increased health care use. The somatic symptom burden is high in patients with cancer who experience pain or depression. Given the strong association with disability and the high prevalence of many types of symptoms, recognizing and managing somatic symptoms may be important in improving quality of life and functional status regardless of type or phase of cancer.

Effects of team care of frequent attenders on patients and physicians.

Frequent clinic attenders consume a large portion of health care resources while feeling underserved. At the same time, physicians are frustrated trying to adequately care for these patients. Previous trials of team care in primary care have rarely included control groups. Adults with eight or more clinic visits in the past year were nonrandomly assigned to usual care or team care. For the latter group, a Care Team met to review each case and create a care plan. Changes in patient health care use, well-being, and satisfaction from baseline to 6 months were compared between team care and usual care patients. In addition, Care Team members' perceptions of team care were assessed by quantitative and qualitative methods. Study patients were medically complex. Self-reported overall well-being and overall care satisfaction improved in the 12-patient team care group, but remained unchanged in the 8 patient usual care group. Median 6-month visits fell by 3 visits among team care patients and increased by 1.5 among usual care patients. Most Care Team members rated team care as positive and as improving quality of care. Members were divided on its effect on care efficiency and workload. Team care is feasible within a family medicine residency practice and may improve care.

Patients with medically unexplained symptoms and their significant others: Illness attributions and behaviors as predictors of patient functioning over time

Objective Previous research suggests that medically unexplained symptoms (MUS) are maintained in an interpersonal context. The current study examined MUS concurrently and prospectively by measuring specific interpersonal predictors of symptom severity and health care use. Methods A total of 127 patients with MUS and their significant others were recruited through primary care offices and assessed with self-report questionnaires and structured interviews about illness attributions, illness behavior and responses, relationship quality, symptom severity, and health care use at baseline and 6-month follow-up. Results Illness attributions and interpersonal illness behaviors of patients with MUS were cross-sectionally associated with illness attributions and responses of the patients' significant others. Relationship quality was related to specific illness behaviors and responses. Symptom severity at baseline was predicted by patients' somatic illness attributions. Symptom severity at 6-month follow-up was predicted by somatic illness attributions of patients and withdrawal of patients' significant others at baseline, but these predictors became insignificant when correcting for baseline symptomatology. Health care use at baseline was predicted by a greater amount of coping behavior and higher anxiety scores of patients, and health care use at 6-month follow-up was predicted by more attention-seeking behaviors and health care use of patients at baseline. Conclusion The results document the interpersonal influences on the maintenance of MUS. The perspective of significant others should be considered for enhancement of psychological approaches to the treatment of patients with MUS.

The role of physical activity and body mass index in the health care use of adults with asthma

Health care use in patients with asthma is affected by many factors, including sex and ethnicity. The role of physical activity (PA) and body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) in this relationship is unknown. To determine the role of PA and BMI in the health care use of patients with asthma. A sample of adults with asthma (n=6,835) and without asthma (n=78,051) from cycle 3.1 of the Canadian Community Health Survey was identified. Health care use was self-reported as overnight hospital stays (yes or no), length of overnight hospital stay (<4 or > or =4 nights), and physician consultations (<3 or > or =3). Self-reported physical activities were used to derive total energy expenditure and to classify participants as active (>3.0 kcal/kg of body weight per day), moderately active (1.5-3.0 kcal/kg of body weight per day), and inactive (<1.5 kcal/kg of body weight per day). The BMI was categorized as normal weight (18.5-24.9), overweight (25.0-29.9), and obese (30.0-59.9). Adjusted logistic regression models revealed that patients with asthma were more likely to have an overnight hospital stay (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.95-2.60), 4 or more overnight hospital stays (OR, 1.48; 95% CI, 1.12-1.96), and 3 or more physician consultations (OR, 2.43; 95% CI, 2.18-2.71) compared with patients without asthma (OR, 1.00). Inactive patients with asthma were more likely to have an overnight hospital stay (OR, 1.68; 95% CI, 1.31-2.16) and 3 or more physician consultations (OR, 1.23; 95% CI, 1.04-1.46) than active patients with asthma (OR, 1.00). Inactive/obese patients with asthma were 2.35 (95% CI, 1.69-3.27) times more likely to have an overnight hospital stay and 2.76 (95% CI, 2.11-3.60) times more likely to have 3 or more physician consultations than active/normal weight patients with asthma (OR, 1.00). Higher PA levels are associated with lower health care use in individuals with and without asthma. In those with asthma, PA was a more important factor in overnight hospital stays than BMI, whereas both BMI and PA were important determinants of physician consultations.

Health Care Use in Patients With Chronic Intestinal Dysmotility Before and After Introducing a Specialized Day-Care Unit

Patients with chronic intestinal dysmotility (CID) have a lifelong disease, and no curative treatment is available. Interventions are needed to improve the care and support of the patients. The aim of this study was to measure health-care consumption in adult patients with CID before and after the introduction of a specialized day-care unit. Retrospective analysis was made of medical and nursing records from 3 different health-care delivery systems: period I, traditional care (1987-1996); period II, outpatient clinic (1997-1999); and period III, specialized day-care unit (2000-2002). There were 54 patients (44 women) with a median age of 47 years (range, 22-80 years). The need for admissions to hospital care decreased from 80% to 35% of the patients after the introduction of the specialized day-care unit (P < .002). Also, the mean number of days in hospital care per patient and year was reduced from 39.4 to 3.3 days. The number of outpatient visits remained unaltered. The average cost per patient-year decreased from $32,698 during traditional health-care services to $9,681 after introducing the specialized day-care unit (P < .002). Irrespective of the form of care delivery, the majority of patients (67%-77%) needed daily treatment with analgesics, and 81%-84% needed nutritional support on a regular basis. Individually tailored care at a specialized day-care unit leads to substantially decreased needs for hospital stays and lower costs in patients with CID.

Choice of a regular physician and health care utilization: principal-agent issues for American veterans

Using US Veterans Health Administration (VA) data, we examined factors that affected patients choice of regular physicians and how the location of regular physicians influenced patients health care use. Appropriate estimation methods were applied to control for the endogeneity of patients choice of regular physicians. Our study showed that VA enrollees with regular VA physicians were more likely to use VA for inpatient care while those with regular nonVA physicians were more likely to use VA for special care such as pharmacy or mental health/substance abuse treatment, both of which can have very limited coverage in nonVA settings.

Follow-up study on health care use of patients with somatoform, anxiety and depressive disorders in primary care

BackgroundBetter management of affective and somatoform disorders may reduce consultation rates in primary care. Somatoform disorders are highly prevalent in primary care and co-morbidity with affective disorders is substantial, but it is as yet unclear which portion of the health care use may be ascribed to each disorder. Our objective was to investigate the use of primary care for undifferentiated somatoform disorders, other somatoform disorders, anxiety and depressive disorders prospectively.MethodsIn eight family practices 1046 consulting patients (25–79 yrs) were screened and a stratified sample of 473 was interviewed. Somatoform disorders, anxiety and depressive disorders were diagnosed (DSM IV) using SCAN 2.1. The electronic records of 400 participants regarding somatic diseases, medication and healthcare use were available through their family physicians (FP).ResultsIn the follow-up year patients with psychiatric disorders had more face-to-face contacts with the FP than patients who had no psychiatric disorder: average 7–10 versus 5. The impact on the use of primary care by patients with somatoform disorders was comparable to patients with depressive or anxiety disorders. Undifferentiated somatoform disorders had an independent impact on the use of primary care after adjustment for anxiety and depressive disorders, resulting in 30% more consultations (IRR 1.3 (95% CI: 1.1–1.7)). Anxiety disorders had no independent effect.ConclusionHealth care planning should focus on the recognition and treatment of somatoform as well as affective disorders.

Effects of Formal Education for Patients with Inflammatory Bowel Disease: A Randomized Controlled Trial

Patients with inflammatory bowel disease (IBD) suffer physical dysfunction and impaired quality of life (QOL), and need frequent health care. They often lack knowledge about their disease and desire more education. Educational interventions for other chronic diseases have demonstrated reduced health care use and increased knowledge, medication adherence and QOL. Sixty-nine participants were randomly assigned to formal IBD education and standard of care (pamphlets and ad hoc physician education) or standard of care alone. Assessment of IBD knowledge and QOL occurred at baseline, immediately posteducation and eight weeks posteducation. Participants documented medication adherence and health care use in diaries. Patient satisfaction was assessed at the end of the study. The education group had higher knowledge scores (P=0.000), perceived knowledge ratings (P=0.01) and patient satisfaction (P=0.001). There was a lower rate of medication nonadherence and health care use for the education group, but the differences were not significant. QOL indices did not change. Significant correlations were found for increased health care use in patients with poorer medication adherence (P=0.01) and lower perceived health (P=0.05). Formal IBD patient education improves knowledge, perceived knowledge and patient satisfaction. Further study of long-term effects may better demonstrate potential benefits for QOL, medication adherence and health care use.

Do childhood adversity and recent social stress predict health care use in patients presenting with upper abdominal or chest pain?

A comprehensive model of health care use by patients with functional gastrointestinal disorders has not been fully tested. This study aimed to establish whether reported childhood and/or recent adversity are independent predictors of health care use when all other relevant factors are also included in the model. Consecutive new patients with upper abdominal or chest pain presenting to a secondary/tertiary clinic were assessed using the Childhood Experience of Care and Abuse and Life Events and Difficulties Schedules. They completed the Hospital Anxiety and Depression and Health Anxiety Questionnaires. Outcome was total number of health care visits recorded in hospital and general practice (GP) records over 18 months. One hundred fifty-one patients were included (65% response rate). Health care visits were most frequent in unmarried (p < 0.0005), females (p < 0.0005), and those lacking social support (p = 0.012). In multiple regression analysis to predict number of health care visits, reported sexual abuse (p = 0.042) and death of a sibling during childhood (p = 0.026) were also independent predictors, together with SF36 subscale scores for physical function, health perception, and mental health (35% of variance explained). Childhood adversity predicted health care use in patients with functional gastrointestinal disorders and recent social stress did so in patients with demonstrated pathological findings. After adjustment for demographic, physical, and psychological factors, childhood adversity, especially in severe form, is an independent predictor of health care use in patients with upper functional gastrointestinal disorders. The same was not true for patients consulting for demonstrable pathological abnormalities, for whom ongoing social stress was an independent predictor.

Traumatic Events, Health Outcomes, and Health Care Use in Patients with Fibromyalgia

Objective: Fibromyalgia syndrome [FMS] is a chronic condition that is resistant to treatment and has no known cause. However, researchers have hypothesized a number of possible antecedents, including traumatic events. The present study examined the relationship between the occurrence and perceived severity of different traumatic events, health outcomes, and health care use in patients with FMS.Methods: Participants were 600 members [95% females, 85% Caucasian, mean age = 54] of a health maintenance organization who met the American College of Rheumatology criteria for FMS. A self-administered questionnaire was used to assess a patient's trauma history. The dependent variables included health status, sleep, pain, depression, and health care utilization.Results: Ninety-one percent of the participants reported experiencing at least one traumatic event prior to the onset of FMS symptoms. The average number of events experienced was 3.6 [SD = 2.3] and, using a 10-point scale, the average severity rating was 7....

Predictors of health care use in patients with Parkinson's disease: a longitudinal study.

To predict health care use in patients with Parkinson's disease. The health care use of 235 patients with Parkinson's disease was studied twice over the course of 1 year. Use consisted of visits to the neurologist and general practitioner (GP) and use of a physiotherapist, a psychotherapist, or home care nurse. The effects of both prior and concurrent sociodemographic, disease-related, and psychosocial characteristics on health care use were examined. Patients who were living with others and patients with private health insurance paid significantly (p <0.01) more visits to their neurologists. For visits to the general practitioner, disease severity and poor quality of life, as measured by the Parkinson's Disease Quality of Life questionnaire (PDQL), were the most important predictors. Other sociodemographic and disease-related characteristics, such as age, gender, and disease duration, were not related to doctor visits. Physiotherapy was associated with disease severity and poor quality of life. Lack of social support, depression, and poor quality of life were correlated with psychotherapy, whereas age, female gender, living alone, disease severity, and disease duration were related to use of a home care nurse. The number of visits to a neurologist by patients with PD is not associated with disease severity or quality of life impairment, but only with sociodemographic characteristics. Nonmedical care is predicted by disease severity and psychosocial characteristics. The consequences for care and costs are discussed.

Cost-effectiveness model of adjunctive lamotrigine for the treatment of epilepsy.

To predict the cost-effectiveness of lamotrigine by evaluating the costs and health outcomes in treated patients. Lamotrigine adjunctive therapy has been found to be associated with decreased seizure frequency and severity in patients who are refractory to treatment with the older antiepileptic drugs (AEDs). We used a cost-effectiveness clinical decision analysis framework to assess the impact of these clinical benefits on patient health care use. The measure of effectiveness was seizure-free days gained. The measures of health care resource use included hospitalizations, outpatient and emergency department visits, surgery, and AEDs. Medical care use and cost estimates were derived from clinical trial data and published sources. Costs and effectiveness (incremental costs per seizure-free days gained) of lamotrigine adjunctive therapy versus older AEDs were compared in patients refractory to previous treatment during three time periods: the start-up year, the second year when decisions about surgery were made, and all subsequent years. The model predicts that use of lamotrigine would be associated with an overall reduction in use of other direct medical care resources (hospitalizations, outpatient visits, diagnostic and laboratory tests, and surgery). For a 10-year time horizon, the estimated cost-effectiveness ratio is $6.9 per seizure-free day gained. The model provides a flexible framework to analyze the effect of new antiepileptic drugs.

B-CAPSA I Haemophilus influenzae, Type b, Capsular Polysaccharide Vaccine Safety

The b-CAPSA I capsular polysaccharide vaccine for Haemophilus influenzae type b was given to 87,541 children 2 through 5 years of age in the Kaiser Permanente Medical Care Program, and the children were then followed using a multiple modality surveillance. Phase 1 consisted of 24-hour recall of immediate side effects which were recorded on questionnaires given to families of 13,500 children. Local side effects were found to be uncommon: 2.3% had a temperature of greater than or equal to 38.3 degrees C (greater than or equal to 101 degrees F); 4.8% had local erythema, 2.9% local swelling, and 12.6% local tenderness; two children had wheezing shortly after immunization. In Phase 2, 30 days after immunization, questionnaires were mailed to parents of all 87,541 children, who were asked to respond to questions about illnesses and health care. Phase 3 consisted of active surveillance of patient health care use by physicians and nurses during the 30 days after immunization. During the 30-day reporting periods, there were 40 hospitalizations, including one for wheezing and one for febrile seizure. Of the 40 hospitalizations, only the one for wheezing was believed by the admitting physician to be probably associated with vaccine administration. Three children had seizures within 30 days of immunization. None of the seizures was believed by the reporting physician to be associated with immunization. Adverse effects of the vaccine were mild, limited to local reactions and occasional temperature elevation; bronchospasm after immunization occurred rarely.
