Adequate Monitoring (adequate + monitoring)
Selected AbstractsMixed venous oxygen saturation is a prognostic marker after surgery for aortic stenosisACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2010J. HOLM Background: Adequate monitoring of the hemodynamic state is essential after cardiac surgery and is vital for medical decision making, particularly concerning hemodynamic management. Unfortunately, commonly used methods to assess the hemodynamic state are not well documented with regard to outcome. Mixed venous oxygen saturation (SvO2) was therefore investigated after cardiac surgery. Methods: Detailed data regarding mortality were available on all patients undergoing aortic valve replacement for isolated aortic stenosis during a 5-year period in the southeast region of Sweden (n=396). SvO2 was routinely measured on admission to the intensive care unit (ICU) and registered in a database. A receiver operating characteristics (ROC) analysis of SvO2 in relation to post-operative mortality related to cardiac failure and all-cause mortality within 30 days was performed. Results: The area under the curve (AUC) was 0.97 (95% CI 0.96,1.00) for mortality related to cardiac failure (P=0.001) and 0.76 (95% CI 0.53,0.99) for all-cause mortality (P=0.011). The best cutoff for mortality related to cardiac failure was SvO2 53.7%, with a sensitivity of 1.00 and a specificity of 0.94. The negative predictive value was 100%. The best cutoff for all-cause mortality was SvO2 58.1%, with a sensitivity of 0.75 and a specificity of 0.84. The negative predictive value was 99.4%. Post-operative morbidity was also markedly increased in patients with a low SvO2. Conclusion: SvO2, on admission to the ICU after surgery for aortic stenosis, demonstrated excellent sensitivity and specificity for post-operative mortality related to cardiac failure and a fairly good AUC for all-cause mortality, with an excellent negative predictive value. [source] Postoperative monitoring of lower limb free flaps with the Cook,Swartz implantable Doppler probe: A clinical trialMICROSURGERY, Issue 5 2010B.Med.Sc., P.G.Dip.Surg.Anat., Ph.D., Warren M. Rozen M.B.B.S. Background: Free flaps to the lower limb have inherently high venous pressures, potentially impairing flap viability, which may lead to limb amputation if flap failure ensues. Adequate monitoring of flap perfusion is thus essential, with timely detection of flap compromise able to potentiate flap salvage. While clinical monitoring has been popularized, recent use of the implantable Doppler probe has been used with success in other free flap settings. Methods: A comparative study of 40 consecutive patients undergoing microvascular free flap reconstruction of lower limb defects was undertaken, with postoperative monitoring achieved with either clinical monitoring alone or the use of the Cook-Swartz implantable Doppler probe. Results: The use of the implantable Doppler probe was associated with salvage of 2/2 compromised flaps compared to salvage of 2/5 compromised flaps in the group undergoing clinical monitoring alone (salvage rate 100% vs. 40%, P = 0.28). While not statistically significant, this was a strong trend toward an improved flap salvage rate with the use of the implantable Doppler probe. There were no false positives or negatives in either group. One flap loss in the clinically monitored group resulted in limb amputation (the only amputation in the cohort). Conclusion: A trend toward early detection and salvage of flaps with anastomotic insufficiency was seen with the use of the Cook,Swartz implantable Doppler probe. These findings suggest a possible benefit of this technique as a stand-alone or adjunctive tool in the clinical monitoring of free flaps, with further investigation warranted into the broader application of these devices. © 2009 Wiley-Liss, Inc.

[source] Psychiatric nurses' attitudes towards patient autonomy in depot clinicsJOURNAL OF ADVANCED NURSING, Issue 4 2001Bodil Svedberg RPN Psychiatric nurses' attitudes towards patient autonomy in depot clinics Aim.,The aim of this qualitative study was to explore how psychiatric nurses experience patient autonomy in relation to their professional role in depot clinics. Background.,The administration of depot neuroleptics at outpatient clinics is a common task for psychiatric nurses in many countries. The procedure is characterized by brief contacts often allowing little opportunity for adequate monitoring of the treatment and a dialog between nurses and patients. As nurses have an important role in involving patients in decision-making, there is a need to analyse the nurses' attitudes towards giving depot neuroleptics from the perspective of autonomy. Method.,Nine experienced psychiatric nurses were interviewed using open-ended questions. The steps of a phenomenological descriptive method guided the data analysis. Findings.,The structure describes how benevolent attitudes towards patient autonomy motivated the nurses' interventions in relation to how they experienced their own professional authority. The structure consists of four variations: (1) Beneficent interventions used with patients perceived as co-operative when the nurses experienced a high degree of professional authority. (2) Paternalistic interventions used with patients perceived as ambiguous towards medication when the nurses experienced an arbitrary professional authority in collaboration with team members. (3) Weak paternalistic interventions used with patients perceived as unwilling when the nurses experienced having sufficient professional authority in the treatment situation. (4) Nonmaleficent interventions used with patients perceived as being resigned when the nurses experienced a low degree of professional authority within the team. Conclusions.,The findings indicate that psychiatric nurses' experience of their professional authority is closely related to the organization of the depot treatment and that brief contacts do not favour the establishment of collaborative relationships with patients. When injection-giving nurses, as patients' key workers, have overall responsibility for co-ordinating the patients' treatment they can encourage patient autonomy by helping patients understand the meaning of depot medication and its benefits. Further clinical research regarding the involvement of nurses in the treatment as well as patients' experiences of treatment with depot neuroleptics is needed to allow suggestions about improvements of the organization of the treatment. [source] Using health information technology to improve drug monitoring: a systematic reviewPHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 12 2009Geoffrey L. Hayward MD Abstract Purpose To conduct a systematic review of current evidence regarding the use of health information technology (HIT) interventions to improve drug monitoring in ambulatory care. Methods We searched PubMed, CINAHL, the Cochrane Library, and other computerized databases from 1 January 1998 to 30 June 2008 using the key words "drug monitoring," "medical records systems, computerized," "ambulatory care," and "outpatients." We manually reviewed reference lists of articles identified through computer searches and asked experts in the field to review our search strategy and results for completeness. Results Seven relevant studies were identified. Four of these studies assessed real-time interventions that used alerts to physicians at the time of medication ordering to ensure adequate monitoring, only one of which showed an improvement in monitoring. Of three studies using HIT outside the physician encounter, two suggested some improvement in monitoring rates. Methodological limitations were apparent in all studies identified. Conclusions Few studies have assessed the effectiveness of HIT interventions to improve drug monitoring, and among them, there is no clear consensus regarding the most consistently effective approaches to reducing drug monitoring errors. There is a clear need for well designed randomized trials to evaluate possible interventions to reduce drug monitoring errors. Such studies should incorporate health outcomes and detailed cost analyses to further characterize the feasibility of successful interventions. Copyright © 2009 John Wiley & Sons, Ltd.
