The effectiveness and efficiency of health promotion in specialty clinic care.

Chronic illnesses make up the majority of health problems in North America. Many chronically ill persons adjust over time to their illnesses; however, there remains a small but important group of those less adjusted, who are concentrated in specialty clinics and are high users of health care resources. This randomized clinical trial investigated the impact of health promotion interventions in the form of problem-solving counseling or phone support that augmented conventional clinic medical care. Chronically ill, poorly adjusted outpatients (n = 293) attending clinics were randomly assigned to receive additional problem-solving counseling, phone call support, or neither. Psychosocial adjustment to illness, utilization, and expenditures of health services were the main outcomes measured. There were no overall significant differences between groups in their change in psychosocial adjustment and expenditures for health and social care. However, interaction analyses (P < 0.05) gave an indication of who might benefit from these interventions. Those who lived alone and infrequently used problem-solving behaviors to cope with their illness significantly improved their adjustment to illness and had fewer health service expenditures if they received problem-solving counseling. Supportive telephone calls were most effective for those who lived with someone and frequently used problem-solving coping behaviors. These findings suggest that health promotion services should be targeted to outpatients described by specific social support and coping characteristics.

A profile of users of specialty pain clinic services: predictors of use and cost estimates.

During the past decade, the multidisciplinary pain clinic has become a popular alternative to the traditional treatment of persistent pain. There is, however, little information describing this population of health care users nor the impact this new demand has on utilization of health care services. The objectives of this study were three fold: to develop a profile of the characteristics of patients referred to a specialty pain clinic including their psychosocial adjustment to their condition; to identify predictors of the use of the specialty services; and to estimate the cost of health service utilization. This historical cohort analytic survey of 571 patients referred to the clinic assessed them for exposure to selected referral variables through a chart review and sampled (n = 222) these patients' current adjustment and health service use through mailed questionnaire. There were four types of use of specialty clinic services. These included: non-users (n = 210); consultation only (n = 180); and the remaining 32% of the referrals were divided between "users-non complete" (n = 98) and "users-complete" (n = 83). "User" groups were similar in characteristics to each other at referral and follow-up on all the major variables with the exception of two factors: non-users lived further from the clinic than users and users were rated as psychologically more vulnerable than non-users. The best predictors for attending the clinic were the presence of referral information from the referring physician and the geographic location of the patient's referring physician. The prevalence of poor psychosocial adjustment was 55.7%, high by comparison with other specialty clinics. Seventy percent of the variance in psychosocial adjustment to chronic pain was explained by social and cognitive variables. In addition, users of specialty pain clinic services generated proportionately less costs in the use of other health services when they were compared to non-users. The importance of social support and meaning of illness variables in predicting psychosocial adjustment to chronic pain is corroborated in this study as is the relevance of the pain clinic cognitive behavioural approach for these problems. In addition, compared to other chronic pain sufferers with similar characteristics, it appears that the use of the pain clinic contains the use of other services and thus has an important economic impact.

Prevalence and correlates of family dysfunction and poor adjustment to chronic illness in specialty clinics.

This study estimated the prevalence of poor adjustment and family dysfunction among three chronically ill clinic patient populations and assessed the biological, situational, social and psychological variables which most explained poor adjustment. Recently referred subjects were approached and 216 chronically ill subjects (from oncology, rheumatology and gastroenterology clinics) completed a Meaning of Illness Questionnaire, the McMaster Family Assessment Device, and the Psychosocial Adjustment to Illness Self-report Scale. In addition, information describing their biological, disease and socioeconomic status was obtained from the clinic record. Respondents were generally representative of other new referrals to the clinics (ineligible for the subsequent trial) in disease characteristics but uniformly came from a more advantaged socioeconomic situation and were better adjusted to illness. Subjects from the three clinics were comparable on meaning, family function and adjustment variables. The proportion of subjects with family dysfunction was 30% and with poor adjustment to illness was 36%, high by community standards. Nevertheless, healthy family functioning and high levels of positive adjustment to chronic illness prevailed and were remarkably similar across clinic settings. Severity or type of disease was not related to adjustment outcomes nor to the level of observed disability. Rather, as hypothesized, meaning given the illness, followed by family function, and disability variables combined to explain 57% of the variance in adjustment outcomes. An intervention designed to improve family function and the meaning given illness was judged suitable.

Individual correlates of health service utilization and the cost of poor adjustment to chronic illness.

It was conjectured that a small group of chronically ill in tertiary ambulatory clinics consume a large amount of health resources and that, from the perspective of the patient, psychosocial rather than disease variables would most explain their health service utilization and subsequent cost. New referrals with a chronic illness (N = 215) to one of three clinics (oncology, rheumatology, and gastroenterology) consented to participate in a subsequent trial of a psychosocial intervention designed to promote their adjustment to illness and, conceivably, to reduce their health service utilization. At baseline an inventory to describe the disease, treatment, functional capacity, prognosis, and socioeconomic situation of consenting subjects was completed. In addition, subjects completed the Psychosocial Adjustment to Illness Inventory (PAIS-SR), the Family Assessment Device (FAD), the Meaning of Illness Questionnaire (MIQ), and a Health Service Utilization Inventory designed to assess direct and indirect costs of health resources. These data were entered into a concurrent analytic survey design. Participating subjects represented a more socioeconomically advantaged and better-adjusted group of chronically ill patients compared with others referred to the tertiary clinics. They were representative of all new referrals in their use of the majority of health services. However, once hospitalized, participating subjects stayed longer and used specialists less. There was no important relationship between disease severity or prognosis and any type of service utilization, including hospitalization. Because the strongest correlate of all types of health services consumed was psychosocial adjustment to illness (r = 0.28 to 0.33), patients were partitioned into one of three categories of adjustment to illness: good, fair, and poor. The total annual cost per patient was $23,883, if poorly adjusted, compared with $9,791 if well adjusted. If cash transfers (benefits paid by different types of insurance) are added, the average 1987 annual cost per poorly adjusted subject was $31,291 per patient, compared with $13,771 for a patient well adjusted to the illness. There was a statistically significant and economically important linear gradient in 1987 treatment costs per category of adjustment. The possible economic implications for psychosocial intervention are highlighted.

Prevalence and characteristics of frequent attenders in a prepaid Canadian family practice.

Frequent attenders in family practice represent a small proportion of the total population, yet they consume a large amount of services. A description of their characteristics and problems is needed in order to design a therapeutic intervention tailored to meet these needs. A comparative analytic survey of 9,313 patients was done in order to isolate three cohorts: 200 zero users in the previous year, 200 modal (one to two times per year) users, and 200 frequent users (nine or more times per year). It was found that frequent attenders (who represented 4.5 percent of the practice, yet generated 21 percent of the annual visits) differ from infrequent attenders in that they have twice the probability of being single; are more physically, socially, emotionally distressed; suffer from problems of self-esteem; show a slightly greater degree of family dysfunction; tend to be unemployed, retired, or mothers of infants; are externally controlled or tend to rely on others for help; receive low incomes, retirement pensions, or family benefits; tend to be high users of other physician, social work, nursing, and laboratory services; consume a significantly greater number of pills than their infrequent user counterparts; and tend to present more emotional and gastrointestinal complaints than their modal user counterparts.

The meaning of illness questionnaire: reliability and validity.

The reliability and validity of a recently developed Meaning of Illness Questionnaire (MIQ) is described. Questionnaire content was based on the work of Lazarus and Folkman (1984b). Three hundred twenty chronically ill subjects completed the 33-item MIQ and two open-ended questions. Subjects also completed the 45-item Psychosocial Adjustment to Illness--Self-Report Scale (PAIS-SR) described by Derogatis and Lopez (1983). Test-retest reliability for 70 subjects was, on the whole, substantial (kappa = .45 to 1.00) as was the ability of nurse clinicians to reliably categorize the qualitative component of the questionnaire into one of 12 categories (kappa = .64). The factor structure of the questionnaire supported the theoretical assumptions underlying the instrument. Three of the factors of meaning given the illness, R2 = .46, and/or three items, R2 = .60, had more power than coping behavior in explaining a person's adjustment to chronic illness. The questionnaire has accumulated reliability and validity in measuring a variety of concurrent yet divergent meanings that may be given an illness for three chronically ill populations--those with mixed cancer, rheumatological, and gastroenterological disorders.
