TOPIC: A culture of safety. PURPOSE: To explore the current culture of blame and what organizational elements must be impacted to move toward a culture of safety in the nursing home setting. METHODS: A mixed-method approach incorporating a case study and staff member survey results were used to explicate the organizational elements impacting the current nursing home culture. CONCLUSION: Nurse leaders can create an environment in which every member of the team feels a responsibility and an ability to insure that residents are safe by improving communication and participation in decision making.  相似文献

OBJECTIVES: To examine the effect of replacing drug-specific computerized prescribing alerts with age-specific alerts on rates of dispensing potentially inappropriate medications in older people and to determine whether group academic detailing enhances the effectiveness of these alerts. DESIGN: Cluster-randomized trial of group academic detailing and interrupted time-series analysis. SETTING: Fifteen clinics of a staff-model health maintenance organization. PARTICIPANTS: Seven practices (113 clinicians, 24,119 patients) were randomly assigned to receive age-specific prescribing alerts plus the academic detailing intervention; eight practices (126 clinicians, 26,805 patients) received alerts alone. Prior implementation of drug-specific alerts established a downward trend in use of target medications that served as the baseline trend for the present study. INTERVENTION: The computerized age-specific alerts occurred at the time of prescribing a targeted potentially inappropriate medication (e.g., tertiary tricyclic amine antidepressants, long-acting benzodiazepines, propoxyphene) and suggested an alternative medication. Clinicians at seven sites were randomized to group academic detailing, an interactive educational program delivering evidence-based information. MEASUREMENTS: Number of target medications dispensed per 10,000 patients per quarter, 2 years before and 1.5 years after the replacement of drug-specific with age-specific alerts. RESULTS: Age-specific alerts resulted in a continuation of the effects of the drug-specific alerts without measurable additional effect (P=.75 for level change), but the age-specific alerts led to fewer false-positive alerts for clinicians. Group academic detailing did not enhance the effect of the alerts. CONCLUSION: Age-specific alerts sustained the effectiveness of drug-specific alerts to reduce potentially inappropriate prescribing in older people and resulted in a considerably decreased burden of the alerts.  相似文献

The aim of this study was to compare the effectiveness of strong advice to withdraw the overused medication with the effectiveness of two structured pharmacological detoxification strategies in a cohort of patients diagnosed with probable migraine overuse headache (MOH) plus migraine and presenting low medical needs. One hundred and twenty patients participated in the study. Exclusion criteria included: previous detoxification treatments, coexistent medical or psychiatric illnesses and overuse of agents containing opioids, benzodiazepines and barbiturates. Group A received only intensive advice to withdraw the overused medication. Group B underwent a standard out-patient detoxification programme (advice+prednisone+preventive treatment). Group C underwent a standard in-patient withdrawal programme (as in group B + fluid replacement and antiemetics). Withdrawal therapy was considered successful if, after 2 months, the patient had reverted to an episodic pattern of headache and to an intake of symptomatic medication on fewer than 10 days/month. We were able to detoxify 75.4% of the whole cohort, 77.5% of patients in group A, 71.7% of patients in group B and 76.9% of those in group C (P>0.05). In patients with migraine plus MOH and low medical needs, effective drug withdrawal may be obtained through the imparting of advice alone.  相似文献

We studied the prevalence and short-term natural course of chronic frequent headache (CFH) in the general population and identified risk factors. In the Netherlands everyone is registered at a single general practice. We sent questionnaires to all persons (n = 21 440) aged 25-55 years, registered at 16 general practices. We compared the characteristics of 177 participants with CFH (>14 headache days/month for >3 months) with 141 participants with infrequent headache (1-4 days/month) and 526 without headache (<1 day/month). The prevalence of CFH was 3.7% [95% confidence interval (CI) 3.4, 4.0]. In 5 months, 12% showed a clinically relevant decrease to <7 days/month. In both headache groups 70% were women vs. 41% in the group without headache. Compared with the group with infrequent headache, the CFH group had more subjects with low educational level [35% vs. 11%; odds ratio (OR) 4.3, 95% CI 2.3, 7.8], medication overuse (62% vs. 3%; OR 38.4, 95% CI 13.8, 106.9), sleeping problems (44% vs. 8%; OR 8.1, 95% CI 3.6, 18.1), a history of head/neck trauma (36% vs. 14%; OR 4.0, 95% CI 2.2, 7.1), high scores on the General Health Questionnaire (62% vs. 34%; OR 2.7, 95% CI 1.3, 3.6) and more smokers (45% vs. 19%; OR 3.1, 95% CI 1.9, 5.3). We conclude that headache frequency fluctuates. CFH is common and associated with overuse of analgesics, psychopathology, smoking, sleeping problems, a history of head/neck trauma and low educational level. Female sex is a risk factor for headache, not for chronification of headache.  相似文献

Aims and objectives. The purpose of this study was to evaluate the effectiveness of a self‐medication programme (SMP) for inpatients of the Nursing Convalescent Unit, a 26‐bed unit with medical and surgical patients. Background. Self‐medication is an important part of self‐management of chronic illness. Self‐medication is a way of allowing patients to give themselves their medications in hospital after receiving education instead of the usual practice of medications administered by a Registered Nurse (RN). Design. The pilot study was undertaken over a six‐month period to examine the relationship between a programme of self‐medication and patient knowledge and adherence to medication regimens, number of medication errors, efficiency in relation to the number of nursing hours associated with the SMP, patient and nursing satisfaction. Methods. A total of 220 patients participated in the study. The SMP included three levels of patient self‐administration of medications: level one, medications administered by a RN; level two, self‐medication directly supervised by a RN and level three, self‐medication indirectly supervised by a RN. Outcome measures included staff and patient satisfaction, number of medication errors, time taken by nurses to undertake activities related to the SMP and the number of patients who achieved levels two and three. Results. Study findings showed that 45% of patients remained on level one, 26% achieved level two and 29% achieved level three. There were no patient initiated medication errors during the study period. Efficiencies were identified in staff workload associated with patient discharge procedures. Overall, nurses perceived that the SMP increased their knowledge of medications and contributed to effective patient education. Conclusions. In selected patients, the SMP was an effective aid for improving adherence to medication regimens. Relevance to clinical practice. Collaboration between nurses, medical staff, pharmacists, patients and carers is integral to the success of in hospital SMP.  相似文献
