Predictors of participation in primary care group-format back pain self-care interventions.

OBJECTIVE: The goal of this study was to explain how primary care back pain patients who volunteer for a group-format self-care intervention differ from nonvolunteers. This is relevant to the generalizability of studies that rely on volunteers as well as the characteristics of patients who do not seek out self-care interventions. SETTING: This study was conducted at a large health maintenance organization in western Washington state. PATIENTS: "Volunteers" (n = 481) were primary care back pain patients participating in randomized trials of a self-management intervention who were recruited through passive nonintensive means (a mailed invitation). "Nonvolunteers" (n = 967) consisted of a representative sample of consecutive back pain patients. We compared the baseline characteristics of these two groups. RESULTS: The relatively small percentage (8%) of primary care back pain patients who volunteered for, and ultimately participated in, group self-management classes tended to be white, older, better educated, and more likely to be retired than nonvolunteers. The two groups did not differ significantly on most clinical measures, including pain intensity and persistence. Patients experiencing the highest (and lowest) levels of pain-related activity interference were less likely to volunteer than those with moderate activity limitations, however. CONCLUSIONS: Those individuals volunteering to participate in a group-format self-care intervention in a primary care setting differed from nonvolunteers primarily on demographic measures as opposed to clinical measures. Back pain patients experiencing the highest levels of activity limitations were somewhat less likely to participate than those with moderate activity limitations. Recruitment for effective self-care interventions is an important issue in determining their impact on a population basis.

Prediction of physician visits and prescription medicine use for back pain.

The primary purpose of this study was to examine the extent to which specific patient attitudes and beliefs about medical care and self-care for back pain predict future healthcare use. An automated database allowed examination of the predictive relationships in two primary care patient samples. In general, beliefs that physicians should find a definitive cause and permanent cure for back pain predicted neither physician visits nor prescription medication fills. Patient attitudes endorsing the benefits of medical treatment for back pain (as opposed to a permanent cure) predicted the use of these specific healthcare services. In a third sample of primary care back pain patients, we assessed whether a four-session self-care intervention modified those attitudes and beliefs shown to predict future healthcare use. The group intervention was associated with changes in attitudes about use of physician services but not medication use. A secondary purpose was to examine initial psychometric properties of a proposed back pain Self-Care Orientation Scale made up of the original 11 items. Factor analyses of the item set yielded three factors, but inconclusive results; the internal consistency of the identified sub-scales was only moderate. However, findings that a subset of items predicted physician visits and prescriptions medication fills, and was sensitive to change following a self-care intervention, suggest avenues for improving measurement of self-care orientation. These findings help clarify specific patient attitudes and beliefs that are related to healthcare utilization and suggest that a subset of these beliefs can be modified through a brief educational intervention.

Achieving guidelines for the treatment of depression in primary care: is physician education enough?

OBJECTIVES: The authors examine whether physician education has enduring effects on treatment of depression. METHODS: Depressed primary care patients initiating antidepressant treatment from primary care clinics of a staff-model health maintenance organization were studied. Quasi-experimental and before-and-after comparisons of physician practices, supplemented with patient surveys, were used to compare the process of care and depression outcomes. Intervention consisted of extensive physician education that spanned a 12-month period. This included case-by-case consultations, didactics, academic detailing (eg, clearly stating the educational and behavioral objectives to individual physicians), and role-play of optimal treatment. Main outcome measures were divided into two groups. Quasi-experimental samples included: (1) antidepressant medication selection and (2) adequacy (dosage and duration) of pharmacotherapy. Survey samples included: (3) intensity of follow-up; (4) physician delivered educational messages regarding depression treatment; (5) patient satisfaction; and (6) depression outcomes. RESULTS: No lasting educational effect was observed consistently in any of the outcomes measured. CONCLUSIONS: There was no enduring improvement in the treatment of depression for primary care patients. Depression treatment guidelines were achieved contemporaneously, however, for intervention patients enrolled in a multifaceted program of collaborative care during the training period. These results suggest that continuing programs of reorganized service delivery to support the role of a primary care physician (eg, on-site mental health personnel, close monitoring of patient progress and adherence), in addition to physician training, are essential for the success of guideline implementation.

The impact of smoking and quitting on health care use.

BACKGROUND: The magnitude and timing of the impact of effects of smoking cessation on inpatient and outpatient health care use are uncertain. METHODS: Comparison of the use of outpatient and hospital services over time of 2440 persistent smokers and 244 biochemically verified quitters, all of whom were participants in two independent randomized trials of smoking cessation interventions. RESULTS: Continued smokers in both trials experienced a 7% to 15% increase in outpatient visits and a 30% to 45% increase in hospital admissions over 5 to 6 years of follow-up. The positive slopes approached or reached statistical significance for all use variables in both trial populations. Among quitters, all health care use rates significantly increased during the year in which they quit; after that, the rates declined progressively. By the fourth year after quitting, all use rates among quitters were lower than those for smokers. The increase in hospitalizations during the year of quitting was more often a cause rather than a consequence of successful smoking cessation. CONCLUSION: Successful smoking cessation appears to halt the progressive increase in the use of health services associated with continued smoking within a 4-year period.

Chronic pain and use of ambulatory health care.

Chronic pain status and health care utilization were assessed in a probability sample of 1016 adult HMO enrollees, and among 242 HMO enrollees seeking treatment for Temporomandibular Disorder (TMD) pain. Likelihood of health care contact for a painful symptom: Among persons reporting back pain, headache, chest pain, abdominal pain or temporomandibular pain in the prior six months, we evaluated whether (1) pain characteristics (severity, persistence, recency of onset), and (2) psychological distress were associated with the likelihood of recent use of health care for each pain symptom. Severity, persistence, and recency of onset of pain were generally associated with recent health care contact for a pain symptom. Females with a pain symptom were no more likely than males to report recent health care contact for the symptom after controlling for pain characteristics. The presence of psychological distress did not increase the likelihood of health care contact for individual pain symptoms. However, psychologically distressed persons were more likely to report pain at multiple anatomical sites and to report recent health care contact for one or more of the five pain symptoms (as a group). Chronic pain status and total use of ambulatory health care: Total number of health care visits (irrespective of reason for visit) was measured by automated data. Chronic pain status (summarized across all five anatomical sites) showed a modest correlation with the volume of health care use. Persons with recurrent pain and severe-persistent pain with no pain-related disability days used ambulatory care at rates close to population means. Persons with severe-persistent pain and seven or more pain related disability days used health care at rates substantially above population means. There was a statistically significant association between the volume of health care use and chronic pain after controlling for age, sex, self-rated health status, and psychological distress.

Participation in a smoking cessation program: a population-based perspective.

We examined factors associated with participation in an HMO-based, self-help smoking cessation trial by comparing participants with nonparticipating smokers who responded to a prior health survey. Recruitment to the trial was accomplished through the HMO's monthly magazine sent to all enrollee households, and the health survey involved a random sample of the enrollee population. Participants were more likely to be female, older, better educated, and heavier smokers with more attempts to quit in the past. Participants consistently reported poorer levels of health status (self-perceived health and energy, life satisfaction, depression, and symptoms), less healthy lifestyles (exercise and dietary fat), and a greater conviction that smoking cessation would improve how they feel than nonparticipants. These findings confirm previous suggestions that formal cessation programs attract those with a more extensive history of addiction, prior failure, and pathophysiologic effects and may provide clues to increasing motivation among smokers with a greater likelihood of treatment success.
