Processes of care: comparison between nurse practitioners and physician residents in acute care.

The purpose of this study was to compare the processes of care (performance of role functions, provision of comprehensive care, coordination of services) of acute care nurse practitioners (ACNPs) and physician residents (PRs) assigned to various medical and surgical programs in acute care settings. A cross-sectional comparative design was used. ACNPs (n = 31) and PRs (n = 10) completed the study questionnaire within two weeks of consenting. Patients who received ACNP care (n = 320) and those who received PR care (n = 46) completed the questionnaire within one week of discharge. The results indicate that ACNPs engaged in management and informal coordination activities more than PRs did, while PRs engaged in more formal coordination activities compared to ACNPs. ACNPs encouraged more patient participation in care and provided more patient education than PRs. These findings, which reflect differences in the processes used by ACNPs and PRs to provide care to patients, could influence the quality and cost outcomes expected of these two groups of healthcare providers.

Practice parameter: temporal lobe and localized neocortical resections for epilepsy.

PURPOSE: To examine evidence for effectiveness of anteromesial temporal lobe and localized neocortical resections for disabling complex partial seizures. METHODS: Systemic review and analysis of the literature since 1990. RESULTS: One intention-to-treat Class I randomized controlled trial of surgery for mesial temporal lobe epilepsy found that 58% of patients randomized to be evaluated for surgical therapy (64% of those who received surgery) were free of disabling seizures and 10 to 15% were unimproved at the end of 1 year, compared with 8% free of disabling seizures in the group randomized to continued medical therapy. There was a significant improvement in quantitative quality-of-life scores and a trend toward better social function at the end of 1 year for patients in the surgical group, no surgical mortality, and infrequent morbidity. Twenty-four Class IV series of temporal lobe resections yielded essentially identical results. There are similar Class IV results for localized neocortical resections; no Class I or II studies are available. CONCLUSIONS: A single Class I study and 24 Class IV studies indicate that the benefits of anteromesial temporal lobe resection for disabling complex partial seizures is greater than continued treatment with antiepileptic drugs, and the risks are at least comparable. For patients who are compromised by such seizures, referral to an epilepsy surgery center should be strongly considered. Further studies are needed to determine if neocortical seizures benefit from surgery, and whether early surgical intervention should be the treatment of choice for certain surgically remediable epileptic syndromes.

Achieving clinical improvement: an interdisciplinary intervention.

This study evaluates whether training health care teams in continuous quality improvement methods results in improvements in the care of and outcomes for patients. Nine of the 25 teams who participated in the study were successful in improving the care/outcomes for patients. Successful teams were more effective at problem solving, engaged in more functional group interactions, and were more likely to have physician participation.
