This paper reports on two studies designed to develop and validate a treatment adherence measure for Children’s Psychosocial Rehabilitation (CPSR)—a home- and community-based treatment for youth with serious emotional disturbance. In Study 1, we derived CPSR treatment adherence and differentiation criteria from a treatment manual and evaluated their content validity via structured feedback from practitioners. In study 2 we assessed the reliability and validity of the resultant CPSR Treatment Adherence Measure (CTAM) in a clinical sample of youth receiving CPSR (n = 11) or outpatient psychotherapy (n = 20). Results from Study 1 revealed strong agreement among practitioners regarding the validity of the proposed adherence criteria (ICC = .82). Results from Study 2 indicated the CTAM had good internal consistency (parent- and supervisor report α’s = .86 & .91) and high inter-rater reliability (r = .87, P = .001) in this pilot sample. CTAM scores reliably distinguished between children receiving CPSR versus psychotherapy (z = −3.16, P = .002) and between CPSR interventionists with reputations for high- (n = 4) or low- (n = 7) adherence to the model (z = −2.47, P = .014). Findings indicate the CTAM is worthy of further development as a practice and research instrument.  相似文献

Infection prevention and control experts have expended valuable health service time developing and implementing tools to audit health workers' hand hygiene compliance by direct observation. Although described as the 'gold standard' approach to hand hygiene audit, this method is labour intensive and may be inaccurate unless performed by trained personnel who are regularly monitored to ensure quality control. New technological devices have been developed to generate 'real time' data, but the cost of installing them and using them during routine patient care has not been evaluated. Moreover, they do not provide as much information about the hand hygiene episode or the context in which hand hygiene has been performed as direct observation. Uptake of hand hygiene products offers an inexpensive alternative to direct observation. Although product uptake would not provide detailed information about the hand hygiene episode or local barriers to compliance, it could be used as a continuous monitoring tool. Regular inspection of the data by infection prevention and control teams and clinical staff would indicate when and where direct investigation of practice by direct observation and questioning of staff should be targeted by highly trained personnel to identify local problems and improve practice.  相似文献

Background

Postabortion insertion of intrauterine contraception has the potential to decrease unintended pregnancy and repeat abortions, but little is known about how to ensure that women receive appropriate counseling about this method in this setting. The goal of this investigation was to document women's questions and to assess retention of information provided during contraceptive counseling after immediate postabortion intrauterine contraceptive placement.

Study Design

Women who received postabortion intrauterine contraceptives (IUCs) at an urban, hospital-based abortion clinic were surveyed 2–3 months postabortion to evaluate for expulsion, assess their concerns about IUC and evaluate retention of information provided during contraceptive counseling.

Results

Of 141 women contacted, 121 participated. Almost half of participants (46%) had responses to the question “Do you have any questions or concerns about your intrauterine device?” that fell into the following categories: spotting/bleeding (16%), cramping/pain (15%), string management (10%), expulsion concern (5%). Seventy percent reported less bleeding during menses than prior to IUC placement, and 37% had less cramping. Sixty-three percent were able to accurately report statistics regarding IUC efficacy, 56% recalled common side effects, and 42% remembered what to do if expulsion occurred.

Conclusion

Although IUCs are highly effective and their placement in the abortion setting is safe, women frequently have questions and do not recall critical counseling information about IUCs. In order to improve IUC continuation, techniques to improve both patient knowledge retention and anticipatory guidance should be studied further.  相似文献

OBJECTIVE: To examine the efficacy of digoxin for decreasing operative time, difficulty, and pain of late second-trimester surgical abortions. METHODS: We performed a randomized, double-masked, placebo-controlled trial of intra-amniotic digoxin for second-trimester dilation and evacuation (D&E) involving 126 consecutive women at an inner-city public hospital. Eligible women had gestational ages of 20-23.1 weeks, spoke English or Spanish, and were at least 16 years old. Digoxin (1 mg) or saline was injected intra-amniotically 24 hours before the procedure, at cervical laminaria insertion. The primary outcome was procedure duration. Sample size was based on 80% power to detect a difference of 3.5 minutes between groups. RESULTS: The two groups were similar in demographic factors, obstetric histories, and gestational duration. The average gestational length was 22.5 weeks. There was no difference in procedure duration (mean +/- standard deviation) between groups (placebo 14.7 +/- 7.0, digoxin 15.4 +/- 8.0). There were no differences in blood loss estimated by surgeons, pain scores, procedure difficulty scores, or complications between groups. Vomiting was significantly more common in those who received digoxin (placebo 3.1%, digoxin 16.1%). Most subjects (91%) reported that they preferred their fetuses were dead before the abortions. CONCLUSION: Although digoxin did not increase efficacy of late second-trimester abortion, patient preference might justify its use.  相似文献

Nurses' mental health is of paramount importance, both in terms of patient safety and the sustainability of the workforce. Age, years in the profession, in post and personal experience or exposure to mental health problems are relevant to the mental health nursing workforce crisis in the United Kingdom. This study aimed to determine the relationship between age, years in the profession and post and self-reported experience of mental health problems using an online cross-sectional survey of 225 UK mental health nurses. Number of years in post was inversely correlated with overall experience of mental health problems, particularly living with someone else with mental health problems. Those with experience of living with someone with mental health problems had significantly fewer years of professional experience than those without. This article discusses possible explanations for this phenomenon and makes the case for future research on the topic.  相似文献

Introduction

The cause of sarcopenia is still not fully understood. A multifactorial aetiology is discussed. Neurodegenerative aspects in the genesis of sarcopenia, such as loss of motoneurons, have not yet been explored to a sufficient extent.

Method

The Motor Unit Number Index (MUNIX) is a method for assessing the number and size (Motor Unit Size Index — MUSIX) of Motor Units (MUs) using the Compound Muscle Action Potential (CMAP) and the Surface electromyographic Interference Pattern (SIP). This method was used to study the hypothenar muscle in the right hand of 27 sarcopenic patients.

Results

The mean MUNIX (111 ± 51) of all investigated sarcopenic patients lies between the mean MUNIX of healthy persons and the mean MUNIX of ALS patients. 25% of sarcopenic patients exhibit pathologic values for both MUNIX (< 80) and MUSIX (> 100 μV). A strong correlation (r = 0.75, p < 0.001) between MUSIX and the reciprocal value of MUNIX was identified.

Conclusion

It was demonstrated for the first time by applying the MUNIX technique that loss of motoneurons plays a pathogenic role in the onset of sarcopenia. This was shown in 25% of sarcopenic participants who exhibited pathologic values for both MUNIX and MUSIX. Nerve sprouting seems to be an important mechanism of compensation for loss of motoneurons, reflected by the strong correlation between MUNIX and MUSIX. Use of MUNIX leads to the identification of a distinct subgroup of sarcopenic patients, which might have a major impact on future diagnostic and therapeutic concepts.  相似文献

Uterine artery embolization in postabortion hemorrhage   总被引:2,自引:0,他引:2  
OBJECTIVE: To summarize the efficacy of postabortion uterine artery embolization in cases of refractory hemorrhage. METHODS: Forty-two women were identified who had postabortion uterine artery embolization at San Francisco General Hospital between January 2000 and August 2007. Seven underwent embolization for hemorrhage caused by abnormal placentation. RESULTS: Embolization was successful in 90% (38 of 42) of cases. All failures (n=4) were in patients who had confirmed abnormal placentation. However, three of seven women (43%) with probable accreta diagnosed by ultrasonography were treated successfully with uterine artery embolization. Two patients experienced complications of uterine artery embolization. These complications-one contrast reaction and one femoral artery embolus-were treated without further sequelae. CONCLUSION: Uterine artery embolization is an alternative to hysterectomy in patients with postabortion hemorrhage refractory to conservative measures, especially when hemorrhage is caused by uterine atony or cervical laceration.  相似文献
