The scope of the cataract problem in the Middle East and the Mediterranean

The region is characterized by diversity in cultural, political, economic and health conditions. Blindness in the region varies from 6.4% to 0.2% with cataract ranking highly as an underlying cause. There is a need to develop national policies to deliver affordable, technically suitable, and cost effective management plans to reduce cataract. Economic, demographic, health, and manpower statistics are essential information to be considered in formulating such policies.     

Assessment of the quality of life in chronic pancreatitis using Sf-12 and EORTC Qlq-C30 questionnaires

BACKGROUND: SF-12 Health Survey, and European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30 are the two main questionnaires proposed and validated for assessing the quality of life in chronic pancreatitis. AIMS: To evaluate the role of the information furnished by both the SF-12 Health Survey and European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30 questionnaires, and to determine which of these two questionnaires may be considered more efficacious, in clinical practice, in describing the quality of life of patients with chronic pancreatitis. PATIENTS: We studied 163 consecutive patients with proven chronic pancreatitis. METHODS: The Italian version of the SF-12 Health Survey and the Italian neutral version of the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30 Version 3.0 questionnaires were administered. RESULTS: Pancreatic pain was the only clinical variable able to significantly impair the SF-12 Health Survey component summaries as well as all domains of the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30, while body mass index was positively related to the physical component summary-12 and to the domains of the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30. A high level of reliability of the domains/scores of the two questionnaires in evaluating the quality of life in patients with chronic pancreatitis was found and two main factors were identified. These two factors were mainly related to the two SF-12 Health Survey summary components. CONCLUSIONS: From a practical point of view, the SF-12 Health Survey is more reliable and easier to use in routine clinical practice than the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-C30.     

Development of quality of care indicators for Parkinson's disease.

Parkinson's disease (PD) is a major cause of disability. To date, there have been no large-scale efforts to measure the quality of PD care because of a lack of quality indicators for conducting an explicit review of PD care processes. We present a set of quality indicators for PD care. Based on a structured review of the medical literature, 79 potential indicators were drafted. Through a two-round modified Delphi process, an expert panel of seven movement disorders specialists rated each indicator on criteria of validity, feasibility, impact on outcomes, room for improvement, and overall utility. Seventy-one quality indicators met validity and feasibility thresholds. Applying thresholds for impact on outcomes, room for improvement, and overall utility, a subset of 29 indicators was identified, spanning dopaminergic therapy, assessment of functional status, assessment and treatment of depression, coordination of care, and medication use. Multivariable analysis showed that overall utility ratings were driven by validity and impact on outcomes (P < 0.01). An expert panel can reach consensus on a set of highly rated quality indicators for PD care, which can be used to assess quality of PD care and guide the design of quality improvement projects.     

Using Queueing Theory to Increase the Effectiveness of Emergency Department Provider Staffing

Objectives: Significant variation in emergency department (ED) patient arrival rates necessitates the adjustment of staffing patterns to optimize the timely care of patients. This study evaluated the effectiveness of a queueing model in identifying provider staffing patterns to reduce the fraction of patients who leave without being seen. Methods: The authors collected detailed ED arrival data from an urban hospital and used a Lag SIPP queueing analysis to gain insights on how to change provider staffing to decrease the proportion of patients who leave without being seen. The authors then compared this proportion for the same 39‐week period before and after the resulting changes. Results: Despite an increase in arrival volume of 1,078 patients (6.3%), an average increase in provider hours of 12 hours per week (3.1%) resulted in 258 fewer patients who left without being seen. This represents a decrease in the proportion of patients who left without being seen by 22.9%. Restricting attention to a four‐day subset of the week during which there was no increase in total provider hours, a reallocation of providers based on the queueing model resulted in 161 fewer patients who left without being seen (21.7%), despite an additional 548 patients (5.5%) arriving in the second half of the study. Conclusions: Timely access to a provider is a critical dimension of ED quality performance. In an environment in which EDs are often understaffed, analyses of arrival patterns and the use of queueing models can be extremely useful in identifying the most effective allocation of staff.     

Evaluation of dietetic activity analysis (DAA)—a system for data collection in clinical dietetics

A system of data collection and analysis based on patient visits was evaluated over a four-week period in five districts and a six-month period in one district by twenty-five dietitians. Each patient visit was analysed by diagnosis (the problem), by diet (the treatment) and by nutritional care level (the action). The system was seen to encourage self analysis by dietitians and proved a useful educational tool in addition to providing dietetic managers with data on clinical dietetic activity. It was considered successful and well accepted in four of the six districts.

Measuring quality and outcomes in intensive care

While quality measures are integral to the maintenance of a high standard of patient care, high-quality care remains a complicated concept to define in the context of acute care. In this article we explore how quality can be measured in the intensive care unit. Standard outcome metrics such as mortality are tangible comparators, but do not offer a comprehensive assessment of quality for the complex heterogeneity of the intensive care population. We explore the Donabedian model as a means to describe the importance of outcomes, processes, structure and environment to inform the measurement of quality. These concepts can be more abstract and difficult to measure but can provide significant insight into the culture of a unit and the resulting performance, and thus provide a more comprehensive measure of quality.     

Cell salvage in burn excisional surgery

BackgroundHemostasis during burn surgery is difficult to achieve, and high blood loss commonly occurs. Bleeding control measures are limited, and many patients require allogeneic blood transfusions. Cell salvage is a well-known method used to reduce transfusions. However, its evidence in burns is limited. Therefore, this study aimed to examine the feasibility of cell salvage during burn surgery.Study design and methodsA prospective, observational study was conducted with 16 patients (20 measurements) scheduled for major burn surgery. Blood was recovered by washing saturated gauze pads with heparinized saline, which was then processed using the Cell Saver. Erythrocyte concentrate quality was analyzed by measuring hemoglobin, hematocrit, potassium, and free hemoglobin concentration. Microbial contamination was assessed based on cultures at every step of the process. Differences in blood samples were tested using the Student’s t-test.ResultsThe red blood cell mass recovered was 29 ± 11% of the mass lost. Patients’ preoperative hemoglobin and hematocrit levels were 10.5 ± 1.8 g/dL and 0.33 ± 0.05 L/L, respectively. The erythrocyte concentrate showed hemoglobin and hematocrit levels of 13.2 ± 3.9 g/dL and 0.40 ± 0.11 L/L thus showing a concentration effect. The potassium level was lower in the erythrocyte concentrate (2.5 ± 1.5 vs. 4.1 ± 0.4 mmol/L, p < 0.05). The free hemoglobin level was low (0.16 ± 0.21 μmol/L). All cultures of the erythrocyte concentrate showed bacterial growth compared to 21% of wound cultures.ConclusionRecovering erythrocytes during burn excisional surgery using cell salvage is possible. Despite strict sterile handling, erythrocyte concentrates of all patients showed bacterial contamination. The consequence of this contamination remains unclear and should be investigated in future studies.
