A linear goal programming model for human resource allocation in a health-care organization.

This paper presents the development of a goal programming (GP) model as an aid to strategic planning and allocation for limited human resources in a health-care organization. The purpose of this study is to assign the personnel to the proper shift hours that enable management to meet the objective of minimizing the total payroll costs while patients are satisfied. A GP model is illustrated using the data provided by a health-care organization in the midwest area. The goals are identified and prioritized. The model result is examined and a sensitivity analysis is performed to improve the model applicability. The GP model application adds insight to the planning functions of resource allocation in the health-care organizations. The proposed model is easily applicable to other human resource planning process.

The World Marrow Donor Association (WMDA): its goals and activities.

The major goal of the World Marrow Donor Association (WMDA) is to facilitate the transfer of hematopoietic cells for transplantation purposes across international borders. It also has the goal of establishing guidelines on ethical, technical, medical, and financial aspects that concern the donor and donor-cell transfer. It has a Board and five Working Groups, namely the Donor Registry Working Group, the Quality Assurance Group, the Ethic Working Group, the Finance Working Group, and the Clinical Working Group. It has three types of membership, that is, full organizational membership, nonvoting organizational membership, and individual corresponding membership. Current important projects are speeding up the search process, accreditation of registries and collecting information about severe adverse effects in donors.

Deep lamellar endothelial keratoplasty (DLEK): pursuing the ideal goals of endothelial replacement.

Endothelial dysfunction is a leading cause of corneal vision loss and treatment requires surgical replacement with donor endothelium. Standard penetrating keratoplasty (PK) suffers from the inherent problems of surface corneal incisions and sutures and poor wound healing of vertical stromal wounds. This often results in high irregular astigmatism, unpredictable corneal power, and the risk of long-term visual loss from suture-induced vascularization, ulceration, rejection, and late wound rupture. This paper delineates five ideal goals of endothelial replacement, which include: (1) a smooth surface topography without significant change in astigmatism from preoperative to postoperative; (2) a highly predictable and stable corneal power; (3) a healthy donor endothelium that resolves all oedema; (4) a tectonically stable globe, safe from injury and infection; and (5) an optically pure cornea. Deep lamellar endothelial keratoplasty (DLEK) is a surgical method of endothelial replacement that is performed through a limbal scleral incision that leaves the surface of the recipient cornea untouched. The early results of this innovative surgery are discussed and compared to the results of PK in terms of fulfillment of the five ideal goals of endothelial replacement. With further refinement of interface creation, DLEK surgery may be the ideal method for endothelial replacement.

Goal negotiation with older people in three day care settings.

Drawing on a wider study of effectiveness in three models of day care, this paper explores the process and outcome of goal negotiation with older people in a day hospital, an outreach service and a day centre. Using qualitative data from interviews with day care attenders and focus groups with service providers, differing perspectives on goal setting and achievement are presented. It concludes with a brief discussion of this approach in the wider context of promoting older people's participation in decision-making in day care settings, where the espoused emphasis is on maintaining and maximising personal autonomy and independent living.

Effects of hyperventilation on fast goal-directed limb movements in spinocerebellar ataxia type 6.

It has been shown previously that hyperventilation modifies the features of the nystagmus in cerebellar patients (Walker and Zee, 1999). It has been hypothesized that hyperventilation influences the oculomotor control through a metabolic effect on cerebellar calcium channels, which play a critical role in the firing behaviour of neuronal populations in the cerebellum. This hypothesis has been tested here by analysing fast goal-directed limb movements before and after hyperventilation in spinocerebellar ataxia type 6 (SCA-6), a disease associated with a polyglutamine expansion in the alpha 1-A voltage-dependent calcium channel. Cerebellar hypermetria associated with fast distal single-joint movements was found to be increased following hyperventilation in patients presenting SCA-6 but remained unchanged in patients with idiopathic late-onset cerebellar degeneration (ILOCA). This is a new provocative test to enhance distal dysmetria in SCA-6. The present results strengthen the hypothesis of Walker and Zee. It is suggested that hyperventilation enhances the defective calcium transfers in SCA-6, resulting in an impairment of the calcium influx in particular into Purkinje cells involved in the control of fast goal-directed voluntary movements.

Goal attainment scaling in the rehabilitation of patients with lower-extremity amputations: a pilot study.

OBJECTIVE: To assess the interrater reliability, construct validity, and responsiveness of Goal Attainment Scaling (GAS) among patients who have had lower-extremity amputations. DESIGN: Pilot study comparing GAS with 2 functional measures with established reliability, validity, and responsiveness values. SETTING: Regional amputee program in southwestern Ontario. PARTICIPANTS: Ten patients (6 women, 4 men; mean age +/- standard deviation, 72.3+/-10.7 y) with unilateral lower-extremity amputations who were consecutively admitted to a regional amputee program. The ratio of transtibial to transfemoral amputations was 6:4. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Subjects were assessed by using GAS, the Barthel Index, and the Locomotor Capabilities Index (LCI) of the Prosthetic Profile of the Amputee. RESULTS: The interrater reliability of GAS was r=.67, and 63% of goals developed were identified independently by both investigators. The construct validity between GAS and the Barthel Index and the LCI was r=.44 and r=.35, respectively. GAS was more responsive than both the Barthel Index and the LCI, as indicated by the calculation of effect sizes and relative efficiencies. CONCLUSION: This pilot study suggests that GAS is a promising outcome measure for the rehabilitation of patients with lower-extremity amputations.

Feasibility and potential clinical utility of goal-directed transthoracic echocardiography performed by noncardiologist intensivists using a small hand-carried device (SonoHeart) in critically ill patients.

OBJECTIVE: This study was designed to assess the clinical applicability of a small, handheld, portable transthoracic echocardiography device by noncardiologist intensivists. DESIGN: Prospective, observational study. After 10 one-hour tutorials, intensivists performed a limited transthoracic echocardiography (TTE) (2-4 views, without Doppler or M-mode) examination with the 5.6-lb SonoHeart Echo System (SonoSite, Bethell, WA) on critically ill patients admitted to the surgical intensive care unit. After initial cardiac clinical assessment in 90 patients, a limited TTE was performed by an intensivist to assess left ventricular (LV) function and LV volume status. Each study was immediately reviewed and repeated by an echocardiographer to determine the technical quality of the TTE and the accuracy of the intensivist's interpretation. Data were analyzed and presented in proportions using descriptive statistics. SETTING: Surgical intensive care unit of an academic medical center. PARTICIPANTS: Ninety critically ill adult patients. INTERVENTIONS: After initial cardiac clinical assessment, a limited TTE was performed by an intensivist to assess LV size and function, to rule out significant pericardial effusions, and to estimate circulatory volume. RESULTS: Intensivists successfully performed a diagnostic limited TTE in 94% of patients and interpreted their studies correctly in 84%. Limited TTE provided new cardiac information and changed management in 37% of patients. TTE added useful information in an additional 47% of patients but did not alter immediate management. The mean "goal-directed TTE" acquisition time was 10.5 +/- 4.2 minutes. CONCLUSION: After a brief formal training in using this handheld echocardiographic system in intensive care unit patients, surgical intensivists successfully performed and correctly interpreted a limited TTE in critically ill patients. Limited TTE provided new information and altered management in a significant number of patients. This study supports incorporating bedside goal-directed, limited TTE into intensivists' training programs.

Therapeutic goals in the treatment of Gaucher disease.

Gaucher disease, the most common lysosomal storage disorder, is a heterogeneous multisystem condition. Patients with non-neuronopathic (type 1) Gaucher disease may suffer from hepatomegaly, splenomegaly, thrombocytopenia, bleeding tendencies, anemia, hypermetabolism, skeletal pathology, growth retardation, pulmonary disease, and decreased quality of life. Enzyme replacement therapy (ERT) with mannose-terminated glucocerebrosidase reverses or ameliorates many of the manifestations of type 1 Gaucher disease. However, the variable disease pattern and severity, and the uncertain manner of progression, render the decision to initiate ERT difficult. Thus, implementation of treatment and evaluation of the therapeutic response must be tailored to the individual patient. To obtain an evidence-based consensus on contemporary therapeutic goals, an international panel of physicians with extensive clinical experience in Gaucher disease met to review the extant literature on its treatment. The panel adopted an integrated system-based approach to arrive at a comprehensive guide to individualized management. Here we establish goals of treatment in Gaucher disease and propose a comprehensive schedule of monitoring of all relevant aspects to confirm the achievement, maintenance, and continuity of the therapeutic response.

Pediatric septic shock: why has mortality decreased?-the utility of goal-directed therapy.

Mortality from septic shock in children has decreased by 92 percent in the last 36 years. The contributions of goal-directed therapy, intensive care, and other forms of support are responsible for this decrease. A deeper and more specific understanding of innate immunity and the biomolecular processes that operate in septic shock has offered the scientific basis to implement goal-directed therapies. However, therapies that are aimed specifically at manipulating the inflammatory cascade have yet to prove safe and effective.

Modification of muscle activation patterns during fast goal-directed arm movements.

The motor programming of fast goal-directed arm movements was studied in a tracking task. A target jumped once or twice randomly to the left or right direction with an interstimulus interval (ISI) in a range between 50 and 125 msec. Double step stimuli were either two steps in the same direction (C-trial) or in opposite direction (R-trial). Tracking results show that at the beginning average EMG-activity is the same for responses to single step trials, R-trials and C-trials. Differences set in after some time equal to or somewhat shorter than ISI. It was concluded that muscle activation patterns of fast goal-directed movements are not preprogrammed but that they can be modified during the movement. The time interval between second target step and the moment when EMG activity of the double step response deviates from the EMG activity of a single step (RT2) could be smaller than the time interval between first target displacement and EMG onset. (RT1). If modification of the muscle activation pattern required a longer or larger activation of the active muscle, RT2 tended to be smaller than RT1, whereas RT2 was about equal to RT1 if the new muscle activation required a termination of the ongoing muscle activation pattern and the activation of another muscle.

Effects of bandwidth goals and bandwidth knowledge of results on motor learning.

An experiment is reported that contrasted two recent hypotheses about the guiding effects of knowledge of results (KR) on motor learning. Specifically, the purpose was to compare the impact of the nature of the KR itself versus the effect of the information conveyed by the KR on learning. We compared four groups of subjects, comprising a factorial combination of KR conditions (specific or bandwidth) and the movement timing goal (specific or bandwidth). All subjects performed 100 acquisition trials and 20 retention trials. The results revealed that bandwidth KR conditions facilitated learning, regardless of the specificity of the movement goal. These effects support the hypothesis that when error KR is provided, its very provision can block error detection activities that are important for retention performance.

Defining and assessing measles elimination goals.

Although 3 of 6 World Health Organization regions have established measles elimination targets, measles elimination goals are not well defined. In general, disease elimination has been defined as the reduction of incidence in a population to zero. However, measles is so contagious that zero incidence is difficult to achieve and sustain because the risk of imported measles remains while measles is endemic in any country. Also, imported cases will occasionally result in short chains of indigenous transmission unless a country achieves 100% immunity. Therefore, the United States currently uses the absence of endemic measles (i.e., no indigenous chains of transmission persisting for >or=1 year) as the programmatic goal for measles elimination. To document the absence of endemic measles in the United States, we compiled information on the epidemiology of measles, genotype distribution, population immunity, and adequacy of measles surveillance. A panel of experts, convened in March 2000 to review the data, concluded that measles is no longer endemic in the United States.

Establishing an appropriate ethical framework: the moral conversation around the goal of prolongevity.

This article presents a triadic framework for ethical discourse around the biogerontological goal of prolongevity, which might someday become achievable through the deceleration of aging. The methods are those of the humanities and philosophical analysis. The perspectives of natural law, equalitarian justice, and beneficence are presented in a balanced manner, although the conclusion reached is that the goal of prolongevity through decelerated aging is ethically valid as a potential means to the beneficent amelioration of the many diseases for which old age is the major susceptibility factor.

An approach to estimating human resource requirements to achieve the Millennium Development Goals.

In the context of the Millennium Development Goals, human resources represent the most critical constraint in achieving the targets. Therefore, it is important for health planners and decision-makers to identify what are the human resources required to meet those targets. Planning the human resources for health is a complex process. It needs to consider both the technical aspects related to estimating the number, skills and distribution of health personnel for meeting population health needs, and the political implications, values and choices that health policy- and decision-makers need to make within given resources limitations. After presenting an overview of the various methods for planning human resources for health, with their advantages and limitations, this paper proposes a methodological approach to estimating the requirements of human resources to achieve the goals set forth by the Millennium Declaration. The method builds on the service-target approach and functional job analysis.

Goal-directed behavior and perception of self-competence in children with spina bifida.

Compared a group of school-age children with spina bifida (n = 15) between the ages of 6 and 12 years with an age- and IQ-matched control group of normal children (n = 15). As predicted, the spina bifida children spent less time using goal-directed behaviors and more time in simple manipulation of the toys compared to the normal children. There were no group differences between the spina bifida and normal children's perceived competence but parents of the spina bifida children rated their children as having lower cognitive and physical competence. Associations were found between goal-directed behaviors and perceived self-competence for children in the spina bifida group but not the normal group.

Western Coordinating Committee-204 goals and why they are important to the future of animal production systems.

There are scientists who believe that science is value-free and that social and ethical issues are not their concern. The birth of Dolly, the cloned lamb, greatly increased public and scientific awareness of ethical issues raised by molecular biology as they intersect with human experience. There are many other issues involving animal production systems, including animal welfare, rural community issues, and environmental concerns. Last year Germany became the first European nation to grant animals a constitutional right. Several European nations ban the use of traditional battery cages for laying hens and gestation crates for sows. In the US, 37 states have recently passed animal anticruelty laws. Times are changing, and if animal production systems are to be part of the future, animal scientists must join with society to solve these ethical issues. The Western Coordinating Committee-204 (WCC-204), Animal Bioethics, has as its goals to 1) create a forum in which animal scientists and nonanimal scientists may work together to examine and discuss contentious social issues, 2) provide a means of encouraging the development of research projects dealing with bioethics of the animal sciences, 3) develop mechanisms of outreach that would allow animal scientists to respond directly to consumers and critics, and 4) provide the means for ongoing critical analysis of the animal science professions in the context of their ability to address moral and sociopolitical issues. Animal scientists can no longer ignore social ethics, and by realizing the goals of Western Coordinating Committee-204, we can help maintain the future of animal production systems.

Goal-directed intraoperative fluid administration reduces length of hospital stay after major surgery.

BACKGROUND: Intraoperative hypovolemia is common and is a potential cause of organ dysfunction, increased postoperative morbidity, length of hospital stay, and death. The objective of this prospective, randomized study was to assess the effect of goal-directed intraoperative fluid administration on length of postoperative hospital stay. METHODS: One hundred patients who were to undergo major elective surgery with an anticipated blood loss greater than 500 ml were randomly assigned to a control group (n = 50) that received standard intraoperative care or to a protocol group (n = 50) that, in addition, received intraoperative plasma volume expansion guided by the esophageal Doppler monitor to maintain maximal stroke volume. Length of postoperative hospital stay and postoperative surgical morbidity were assessed. RESULTS: Groups were similar with respect to demographics, surgical procedures, and baseline hemodynamic variables. The protocol group had a significantly higher stroke volume and cardiac output at the end of surgery compared with the control group. Patients in the protocol group had a shorter duration of hospital stay compared with the control group: 5 +/- 3 versus 7 +/- 3 days (mean +/- SD), with a median of 6 versus 7 days, respectively ( = 0.03). These patients also tolerated oral intake of solid food earlier than the control group: 3 +/- 0.5 versus 4.7 +/- 0.5 days (mean +/- SD), with a median of 3 versus 5 days, respectively ( = 0.01). CONCLUSIONS: Goal-directed intraoperative fluid administration results in earlier return to bowel function, lower incidence of postoperative nausea and vomiting, and decrease in length of postoperative hospital stay.

Nissen fundoplication in children with profound neurologic disability. High risks and unmet goals.

Anti-reflux procedures have been advocated in children with profound neurologic disability referred for feeding gastrostomy when gastroesophageal reflux is present. Facilitation of care, reduction in pneumonia and vomiting, and improvement in the general health and survival of these children have been major goals of fundoplication and gastrostomy. In large pediatric series, these procedures have been reported to have low risk and negligible mortality rates. Recent reports, however, document an increased incidence of sequelae of fundoplication in children with profound neurologic disability. This paper retrospectively reviews a series of 35 nonverbal, nonambulatory pediatric patients undergoing a total of 39 fundoplications (37 Nissen, 1 Thal, and 1 Belsey) over an 11-year period. Neurologic impairment of 17 (49%) patients was acquired, 13 (37%) congenital, and 5 (14%) due to a syndrome. Perioperative complications occurred in six (17%). Three additional complications led to early postoperative death. A fourth early death was unexplained. Fourteen (40%) had recurrent pneumonia, 11 (31%) recurrent vomiting, 8 (23%) choking-gagging-retching complex, and 3 (9%) bowel obstruction requiring laparotomy. Recurrent gastroesophageal reflux was documented in seven (20%) patients. A second ARP was performed in six (17%). There were 14 (40%) late deaths. Although the major goals of anti-reflux procedure are clearly achieved in many severely impaired children with gastroesophageal reflux, the use of Nissen fundoplication to resolve the complications of swallowing disorders and improve outcome with an acceptably low risk in this complex set of patients does not appear to be established.
