A specialized home care intervention improves survival among older post-surgical cancer patients.

CONTEXT: Changes in the healthcare system have resulted in shortened hospital stays, moving the focus of care from the hospital to the home. Patients are discharged post-operatively with ongoing needs, and whether they receive nursing care post-hospitalization can influence their recovery and survival. Little information is available about the factors that influence outcomes, including the survival of older cancer patients after cancer surgery. OBJECTIVE: To compare the length of survival of older post-surgical cancer patients who received a specialized home care intervention provided by advanced practice nurses (APNs) with that of patients who received usual follow-up care in an ambulatory setting. We also assessed potential predictors of survival in terms of depressive symptoms, symptom distress, functional status, comorbidities, length of hospital stay, age of patient, and stage of disease. DESIGN: A randomized controlled intervention study. SETTING: Discharged older cancer patients after surgery at a Comprehensive Cancer Center in southeastern Pennsylvania. PATIENTS: Three hundred seventy-five patients aged 60 to 92, newly diagnosed with solid cancers, were treated surgically between February 1993 and December 1995. One hundred ninety patients were randomized to the intervention groups and 185 to the usual care group. INTERVENTION: The intervention was a standardized protocol that consisted of standard assessment and management post-surgical guidelines, doses of instructional content, and schedules of contacts. The intervention lasted 4 weeks and consisted of three home visits and five telephone contacts provided by APNs. Both the patients and their family caregivers received comprehensive clinical assessments, monitoring, and teaching, including skills training. MAIN OUTCOME MEASURE: Time from enrollment of patients into the study until death or last date known alive at the end of November 1996. RESULTS: During the 44-month follow-up period, 93 (24.8%) of 375 patients died. Forty-one (22%) of those who died were patients in the specialized home care intervention group, compared with 52 (28%) in the usual care group. Stage of disease at diagnosis differed between the two groups at baseline (38% late stage patients in the intervention group compared with 26% in the control group, P = .01), so stratified analysis was performed. Overall, the specialized home care intervention group was found to have increased survival (P = .002 using stratified log-rank test). Among early stage patients only, there was no difference in survival between the intervention and control groups. Among late stage patients, there was improved survival in the intervention group. For example, 2-year survival among late stage intervention group cases was 67% compared with 40% among control cases. When Cox's proportional hazard model was used to adjust for significant baseline covariates, the relative hazard of death in the usual care group was 2.04 (CI: 1.33 to 3.12; P = .001) after adjusting for stage of disease and surgical hospitalization length of stay. CONCLUSIONS: This is the first empirical study of post-surgical cancer patients to link a specialized home care intervention by advanced practice nurses with improved survival. Additional research is needed to test home care interventions aimed at maintaining quality of life outcomes and their effects on survival of post-surgical cancer patients.

A comparison of social functioning among black and white women with breast cancer.

Results of a comparative study of interviews with 102 women (61 white, 41 black) who were treated for breast cancer suggest that black women have more difficulty in social functioning, especially the resumption of household activities. Implications for social work practice are discussed.

Testing a theory for health-related quality of life in cancer patients: a structural equation approach.

The purpose of this study was to test a Roy Adaptation Model-based theory of health-related quality of life in patients with newly diagnosed cancer. Using a structural equation model, health-related quality of life (HRQOL) was regarded as a latent variable measured by 4 empirical indicators representing the 4 biopsychosocial response modes of the Roy Adaptation Model (RAM). The response modes are physiologic, self-concept, interdependence, and role function. These were empirically represented by physical symptoms, affective status, social support, and functional support, respectively. In this secondary analysis, 3 RAM propositions were tested in a sample of 375 newly diagnosed postsurgical cancer patients 60 years and over. These were: (a) that the 4 response modes are interrelated; (b) that environmental stimuli of gender, race, age, income, marital status, cancer treatment, and severity of illness influence the biopsychosocial response modes; and (c) that the biopsychosocial responses soon after diagnosis predict biopsychosocial responses 3 months later. The analyses did not support the proposition that all 4 response modes were interrelated. The results, however, revealed that severity of illness and adjuvant cancer treatment had the strongest association with the biopsychosocial responses and should be considered the focal environmental stimuli. The remaining environmental stimuli can be considered contextual. Also, the proposition that initial biopsychosocial responses predicted later responses was supported.

A test of the fit between the Corbin and Strauss Trajectory Model and care provided to older patients after cancer surgery.

The Corbin and Strauss Trajectory Model proposed that nursing care should differ along a trajectory of eight phases to meet patients' and families' needs. Seventy-nine patients with breast, prostate, or gastrointestinal cancer were determined to be in either the stable or the unstable phase of their illness. Contrary to expectations, documented nursing interventions did not significantly differ between stable and unstable trajectory phases, although significant differences were found when comparisons were made across cancer sites. These findings suggest that the trajectory framework may require modification for use with oncology patients.

Evaluation of HER-2/neu (c-erbB-2) oncogene expression in whole organ sections of supraglottic squamous cell carcinoma.

Adequate pathologic material and careful clinical follow-up are prerequisites for the analysis of the expression of particular oncogenic proteins that are prognostically important in squamous cell carcinoma of the larynx. The Gabriel Tucker, Jr, Collection of 150 whole organ specimens allows for the potential immunohistochemical study of the entire tumor. Sections from 32 supraglottic carcinomas were studied immunohistochemically for the presence of HER-2/neu (c-erbB-2) oncogene expression. Long-term follow-up data were available in all cases to assist in determining the prognostic significance of the specified oncogene in supraglottic squamous cell carcinoma. Our study revealed that joint presentation of immune staining for c-erbB-2 and positive lymph node status was significantly associated with distant metastasis (p=.00760).

A prospective longitudinal investigation of spousal bereavement examining Parkes and Weiss' Bereavement Risk Index.

The purpose of this study was (a) to describe spousal bereavement both prospectively and longitudinally and (b) to examine the validity of the Bereavement Risk Index (BRI) published by Parkes and Weiss (1). Psychological distress was measured in 46 subjects across five time intervals beginning prior to a spousal death from lung cancer and ending 25 months after the death using the Brief Symptom Inventory (BSI) (2). The hypothesis that the BRI discriminates between bereaved spouses at high and low risk for psychological distress was supported by measurements taken within two months of the patient's diagnosis (prior to death), at 6 weeks following the death, and at 6 and 13 months thereafter. These findings support the need for early identification of individuals at high risk for negative bereavement outcomes even prior to the spousal death.

Clinical management of keratoconus. A multicenter analysis.

The clinical management of 746 eyes in 417 patients referred for keratoconus from January 1984 through January 1988 was retrospectively analyzed. In 357 patients, 554 eyes (74%) did not require surgery and were managed with contact lenses or spectacles, 156 eyes (21%) in 137 patients either underwent penetrating keratoplasty (PK) (140 eyes) or surgery was recommended (16 eyes), and 36 eyes (4%) in 34 patients underwent epikeratoplasty. Comparing baseline and final examination findings, the nonsurgical group showed a significant improvement in average best-corrected visual acuity from 20/30 to 20/25, the PK group from 20/70 to 20/25, and the epikeratoplasty group from 20/40 to 20/30. Average keratometry was unchanged in the nonsurgical group, but decreased by 10.7 diopters (D) for the PK group and 6.5 D for the epikeratoplasty group. Corneal cylinder was unchanged in the nonsurgical group, whereas there was a reduction of the percentage of eyes with indeterminant cylinder from 55 to 2% in the PK group and from 36 to 0% in the epikeratoplasty group. Previous contact lens history, best-corrected visual acuity of 20/50 or worse, and average keratometry of 55 D or greater at baseline were associated with a significant risk for PK. No baseline variables were associated with significant risk for epikeratoplasty, suggesting that this group was similar to the nonsurgical group, except for contact lens intolerance. The nonsurgical management of keratoconus continues to play a predominant role in the management of this disorder in a referral population.
