Extreme altitude mountaineering and Type 1 diabetes; the Diabetes Federation of Ireland Kilimanjaro Expedition

DIABETIC MEDICINE, Issue 9 2001
K. Moore
Abstract Aims To examine the effects of extreme altitude mountaineering on glycaemic control in Type 1 diabetes, and to establish whether diabetes predisposes to acute mountain sickness (AMS). Methods Fifteen people with Type 1 diabetes and 22 nondiabetic controls were studied during the Diabetes Federation of Ireland Expedition to Kilimanjaro. Daily insulin requirements, blood glucose estimations and hypoglycaemic attacks were recorded in diaries by the people with diabetes. The performance of blood glucose meters at altitude was assessed using standard glucose solutions. Symptoms of acute mountain sickness were recorded daily by people with diabetes and by the nondiabetic controls using the Lake Louise Scoring Charts. The expedition medical team recorded the incidence of complications of altitude and of diabetes. The final height attained for each individual was recorded by the expedition medical team and verified by the expedition guides. Results The final altitude ascended was lower in the diabetic than the nondiabetic group (5187 ± 514 vs. 5654 ± 307 m, P= 0.001). The mean daily insulin dose was reduced from 67.1 ± 28.3,32.9 ± 11.8 units (P < 0.001), but only 50% of recorded blood glucose readings were within the target range of 6,14 mmol/L. There were few hypoglycaemic attacks after the first two days of climbing. Both blood glucose meters tested showed readings as low as 60% of standard glucose concentrations at high altitude and low temperatures. The Lake Louise questionnaires showed that symptoms of AMS occurred equally in the diabetic and nondiabetic groups. There were two episodes of mild diabetic ketoacidosis; two of the diabetic group and three of the nondiabetic group developed retinal haemorrhages. Conclusions People with Type 1 diabetes can participate in extreme altitude mountaineering. However, there are significant risks associated with this activity, including hypoglycaemia, ketoacidosis and retinal haemorrhage, with the additional difficulties in assessing glycaemic control due to meter inaccuracy at high altitude. People with Type 1 diabetes must be carefully counselled before attempting extreme altitude mountaineering. Diabet. Med. 18, 749,755 (2001) [source]

Add-on Phenytoin Fails to Prevent Early Seizures after Surgery for Supratentorial Brain Tumors: A Randomized Controlled Study

EPILEPSIA, Issue 2 2002
Antonio De Santis
Summary: ,Purpose: To determine the potential effectiveness of phenytoin (PHT) in preventing early postoperative seizures in patients undergoing craniotomy for supratentorial brain tumors. Methods: Two hundred patients requiring elective craniotomy for supratentorial brain tumors were randomized to two groups of equal size, with a prospective, open-label, controlled design. One group received PHT (18 mg/kg as an intravenous intraoperative load, followed by additional daily doses aimed at maintaining serum PHT concentrations within the 10- to 20-æg/ml range) for 7 consecutive days. In the other group, PHT was not administered. More than 90% of patients in both groups continued to take preexisting anticonvulsant medication (AEDs) with carbamazepine or phenobarbital throughout the study. The primary efficacy end point was the number of patients remaining free from seizures during the 7-day period after the operation. Results: Of 100 patients allocated to PHT, 13 experienced seizures during the 7-day observation period, compared with 11 of 100 patients in the placebo group (p > 0.05). Most seizures occurred in the first day after surgery in both groups. There were no differences between groups in the proportion of patients experiencing more than one seizure, but there was a trend for generalized seizures to be more common in PHT-treated patients than in controls (11 vs. five patients, respectively). Status epilepticus occurred in one patient in the PHT group and in two patients in the control group. Of the 13 PHT-treated seizure patients, 11 had serum PHT concentrations within the target range, and only two had concentrations below range on the days their seizures occurred. Conclusions: PHT, given at dosages producing serum concentrations within the target range, failed to prevent early postoperative seizures in patients treated with concomitant AEDs. Prophylactic administration of PHT cannot be recommended in these patients. [source]

EARNINGS MANAGEMENT IN ENGLISH NHS HOSPITAL TRUSTS

FINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 4 2007
Joan Ballantine
In this paper we review the financial reporting incentives associated with the requirement to breakeven for English NHS Trusts. We also investigate the distribution of reported income and estimate discretionary accruals thereby contributing to the limited literature on earnings management in not-for-profit hospitals. We find that Trust managers use discretion over accruals to report income within the target range around zero. The results are robust to recent challenges to earnings management explanations arising from the use of distributional and aggregate accruals methodologies. Our findings indicate that a precise and challenging financial breakeven target based on current cost residual income is associated with wide-spread use of discretionary accruals to an extent that weakens the accountability of NHS Trusts.

Lack of management of cardiovascular risk factors in type 2 diabetic patients

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 1 2007
K. E. Yun
Summary Effective management of diabetic patients includes comprehensive control for not only blood sugar, but also other cardiovascular risk factors. We assessed whether haemoglobin A1c (A1C) concentrations, blood pressure, low density lipoprotein (LDL) cholesterol levels and microalbuminuria were regularly measured in 281 patients with type 2 diabetes who received care for over 1 year in the Department of Family Medicine located in an urban area of Korea. Subsequently, in patients with A1C > 7%; blood pressure >130/80 mmHg; LDL cholesterol levels >100 mg/dl; or microalbuminuria, we evaluated the status of management for those cardiovascular risk factors. Physicians were most likely to measure A1C levels (98.6%), but less likely to measure microalbuminuria (56.2%), LDL cholesterol (73.7%), or blood pressure (74.4%). Patients whose A1C levels were above the goal (78.2%) were likely to receive optimal therapy. In contrast, only 21.1% of patients with uncontrolled blood pressure and 5.3% of patients with LDL cholesterol levels above the target range received optimal management. Of the 36 patients with microalbuminuria or overt proteinuria, 66.7% took angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Measurement of parameters indicating cardiovascular risk factors in type 2 diabetic patients was not optimal, particularly regular measurements for microalbuminuria and for controlling LDL-cholesterol and blood pressure. These findings indicate a need for greater education of comprehensive cardiovascular management in type 2 diabetic patients and their physicians. [source]

Relationships of tacrolimus pharmacokinetic measures and adverse outcomes in stable adult liver transplant recipients

JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 1 2006
C. Dansirikul PhD
Summary Background and objectives:, Alternative measures to trough concentrations [non-trough concentrations and limited area under the concentration,time curve (AUC)] have been shown to better predict tacrolimus AUC. The aim of this study was to determine if these are also better predictors of adverse outcomes in long term liver transplant recipients. Methods:, The associations between tacrolimus trough concentrations (C0), non-trough concentrations (C1, C2, C4, C6/8), and AUC0,12 and the occurrence of hypertension, hyperkalaemia, hyperglycaemia and nephrotoxicity were assessed in 34 clinically stable liver transplant patients. Results and discussion:, The most common adverse outcome was hypertension, prevalence of 36%. Hyperkalaemia and hyperglycaemia had a prevalence of 21% and 13%, respectively. A sequential population pharmacokinetic/pharmacodynamic approach was implemented. No significant association between predicted C0, C1, C2, C4, C6/8 or AUC0,12 and adverse effects could be found. Tacrolimus concentrations and AUC measures were in the same range in patients with and without adverse effects. Conclusions:, Measures reported to provide benefit, preventing graft rejection and minimizing acute adverse effects in the early post-transplant period, were not able to predict adverse effects in stable adult liver recipients whose trough concentrations were maintained in the notional target range.

Severe hypoglycemia during intensive insulin therapy

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2009
K.-M. KAUKONEN
Background: Tight glycemic control reduces mortality in surgical intensive care patients and in long-term medical intensive care patients. A large study on intensive insulin therapy was prematurely discontinued due to safety issues. As the safety of intensive insulin therapy has been questioned, we screened all patients during a 17-month period to reveal the incidence of hypoglycemia and its effects on the outcome of the patients. Methods: All patients treated between February 2005 and June 2006 in two intensive care units (ICUs) of a tertiary care teaching hospital were included in the study. A nurse-driven intensive insulin therapy with a target blood glucose level of 4,6 mmol/l had been introduced earlier. The patients were divided into two groups according to the presence of severe hypoglycemia (,2.2 mmol/l). Results: One thousand two hundred and twenty-four patients (1124 treatment periods) were included. During the study period, 61,203 blood glucose measurements were performed, 2.6% of which were below and 52.6% above the target range. Severe hypoglycemia (glucose ,2.2 mmol/l) occurred in 25 patients (36 measurements). The incidence was 0.06% of the measurements and 2.3% of the patients. The median age, sex, Acute Physiology And Chronic Health Evaluation II, Simplified Acute Physiology Score II, diagnosis category, ICU or hospital length of stay did not differ between the groups. The hospital mortalities were 25% and 15% in patients with or without severe hypoglycemia, respectively (P=0.16). Conclusion: Severe hypoglycemia during intensive insulin therapy is rare in clinical practice compared with previous clinical trials. [source]

INTRAVENOUS IRON IN CHRONIC KIDNEY DISEASE: HAEMOGLOBIN CHANGE SHORTLY AFTER TREATMENT OF PATIENTS NEITHER ON DIALYSIS NOR ON ERYTHROPOIETIN

JOURNAL OF RENAL CARE, Issue 3 2008
Senyo Tagboto
SUMMARY Anaemia is a common in chronic kidney disease. Although erythropoietin and iron supplementation are established treatments, knowledge on the use of IV iron alone in patients not on dialysis or erythropoietin is incomplete. The responses of 82 patients referred to the renal anaemia service with haemoglobin of 11.5 g/dl or less were assessed 1 week after completing four once weekly doses of 200 mg of venofer. No patients were on dialysis or erythropoietin. The haemoglobin rise 1 week after treatment was 0.53 g/dl. Ferritin levels improved from 110.8 to 410.2 ng/l and transferrin saturation from 17.7 to 27.3%. Ferritin levels remained below our target range (200,500 ng/l) in 7.7% while 25.6% had levels above this. Ferritin levels remained less than 800 ng/l in nearly all patients. Intravenous iron is cost effective and should be considered for use in patients with renal anaemia. Patients with CKD stage 5 appeared to respond less well. [source]

Warfarin for atrial fibrillation in community-based practise

JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 10 2008
A. J. ROSE
Summary.,Background:,Previous studies of anticoagulation for atrial fibrillation (AF) have predominantly occurred in academic settings or randomized trials, limiting their generalizability.Objective:,To describe the management of patients with AF anticoagulated with warfarin in community-based practise.Methods:,We enrolled 3396 patients from 101 community-based practises in 38 states. Data included demographics, comorbidities, and International Normalized Ratio (INR) values. Outcomes included time in therapeutic INR range (TTR), stroke, and major hemorrhage.Results:,The mean TTR was 66.5%, but varied widely among patients: 37% had TTR above 75%, while 34% had TTR below 60%. The yearly rates of major hemorrhage and stroke were 1.90 per 100 person-years and 1.00 per 100 person-years. Four percent of patients (n = 127) were intentionally targeted to a lower INR, and spent 42.7% of time with an INR below 2.0, compared to 18.8% for patients with a 2.0,3.0 range (P < 0.001). Mean TTR for new warfarin users (57.5%) remained below that of prevalent users through the first six months. Patients with interruptions of warfarin therapy had lower TTR than all others (61.6% vs. 67.2%, P < 0.001), which corrected after deleting low peri-procedural INR values (67.0% vs. 67.4%, P = 0.73).Conclusions:,Anticoagulation control varies widely among patients taking warfarin for AF. TTR is affected by new warfarin use, procedural interruptions, and INR target range. In this community-based cohort of predominantly prevalent warfarin users, rates of hemorrhage and stroke were low. The risk versus benefit of a lower INR target range to offset bleeding risk remains uncertain. [source]

The quality of oral anticoagulant therapy and recurrent venous thrombotic events in the Leiden Thrombophilia Study

JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 5 2007
A. P. A. GADISSEUR
Summary.,Background:,The International Normalized Ratio (INR) target range is a relatively narrow range in which the efficacy of oral anticoagulant treatment, i.e. prevention of extension and recurrence of thrombosis, is balanced with the risk of hemorrhagic complications. Over the years, different INR target ranges have been implemented for individual indications, depending on their thrombotic potential. In most of the studies defining these INR targets, the treatment of the patients was aimed at a certain INR range, but in the analysis no account was taken of the time that the patients spent within this range in reality. Methods:,The Leiden Thrombophilia Study (LETS) is a population-based case-control study on risk factors for venous thrombosis, in which many genetic and acquired factors have been investigated. Our aim was to investigate the effect of the quality of the oral anticoagulant therapy for the initial venous thrombosis and its relationship with recurrence of thrombosis. Quality of anticoagulation was defined as the time spent at various INR levels during treatment, and we focused on the effect of sustained intensities above a certain INR in preventing recurrences later on. Results:,Two hundred and sixty-six patients with a total follow-up of 2495 patient-years were studied. The mean duration of the initial anticoagulant therapy was 194.5 days (range 48,4671). During follow-up, 58 recurrences were diagnosed (cumulative recurrence rate of 21.8% over 9 years). The mean INR during initial therapy was 2.90, with 90.3% [95% confidence interval (CI) 88.4,92.3%] of the time being spent above an INR of 2.0, and 39.1% (95% CI 35.5,42.7%) above an INR of 3.0. Patients who spent more time below the target range, or who had a shorter duration of anticoagulation, did not experience a higher risk of recurrence after the initial period of anticoagulation had passed. Conclusion:,Provided that oral anticoagulant treatment is adequately managed, according to international guidelines, recurrent thrombosis cannot be ascribed to variation in the primary treatment. Further attempts to reduce the risk of recurrence should therefore be aimed at identifying other explanatory factors, and subsequently fine-tuning the target ranges. [source]

C2 monitoring of cyclosporine in de novo liver transplant recipients: The clinician's perspective

LIVER TRANSPLANTATION, Issue 5 2004
Federico Villamil
Adjusting cyclosporine (CsA) dose based on blood concentration at 2 hours after dose (C2) has been shown in prospective clinical trials to reduce the risk of rejection compared with conventional trough monitoring. In addition, it provides equivalent efficacy to tacrolimus in liver transplant patients, with a favorable safety profile. Target C2 should be defined on an individual basis depending on adjunctive therapy and the level of exposure required. It appears less critical to achieve target C2 in the first few days after liver transplantation than was previously believed. Achieving target C2 exposure in the initial period after transplant requires that changes in the proportion of cyclosporine absorbed from the gut be taken into account to avoid risk of overexposure. In addition, if a starting dose of 10,15 mg/day is used, it is advisable to delay increasing the dose until a trend in C2 level indicates this to be necessary. Immediate dose reduction is required if C2 exceeds target range. In patients with low C2 values, cyclosporine concentration at a later time point should be measured to establish whether the patient is a poor absorber or a delayed absorber of C2, and dose adjustments should be undertaken accordingly. In conclusion, this more flexible approach to C2 monitoring allows the dose of cyclosporine to be individualized effectively for each patient, which results in significant efficacy benefits while minimizing the risk of toxicity.

Characteristics of glycemic control in young children with type 1 diabetes

PEDIATRIC DIABETES, Issue 4 2002
Francine Ratner Kaufman
Abtract: Background: The Diabetes Control and Complications Trial (DCCT) demonstrated that the rate-limiting step to the intensification of diabetes management in adolescents and adults was hypoglycemia. Young children were presumed to be at even greater risk for hypoglycemia with severe consequences, particularly if they had HbA1c levels < 8%. Subjects: A retrospective chart review was performed on 148 patients with type 1 diabetes on insulin injection therapy who were < 8 yr of age (mean age 5.7 ± 1.5, mean diabetes duration 3.0 ± 1.4 yr) followed quarterly from July 1999 to June 2001. Methods:, The subjects were divided into two groups based on their mean HbA1c values (< 8 vs. , 8%) averaged over the 2-yr time period. The following variables were analyzed comparing the two groups: age, duration of diabetes, insulin dose, severe hypoglycemic episodes, episodes of diabetic ketoacidosis (DKA), percentage of glucose levels above, within, and below the target range, and number of diabetes home-management competencies obtained. Results:, Patients with HbA1c < 8% spent more time within target range (40.0 vs. 29.5%, p = 0.0001) and less time above their target range (36.9 vs. 51.2%, p = 0.0003). There was no difference in the percentage of glucose levels below target (23.2 vs. 19.4%, p = NS), percentage of severe hypoglycemic episodes (3 vs. 7 episodes per 100 patient-yr, p = NS), or episodes of DKA (1 vs. 3 episodes per 100 patient-yr, p = NS) between the two groups. Subjects with lower HbA1c levels had acquired more home-management competencies (4.0 vs. 3.5, p = 0.01). Conclusions:, If families are competent in fundamental diabetes management, young children can achieve HbA1c levels < 8.0% without increasing the risk of hypoglycemia. [source]

Utility of azathioprine metabolite measurements in post-transplant recurrent autoimmune and immune-mediated hepatitis

PEDIATRIC TRANSPLANTATION, Issue 6 2004
Carolina Rumbo
Abstract:, Patients with post-transplant immune-mediated hepatitis (IMH) and recurrent autoimmune hepatitis (RAIH) have a poor outcome and a higher need for retransplantation. Azathioprine (AZA) is used as adjunctive immunosuppression after transplantation; optimizing its dose may be a key point in preserving graft function. Complications of high AZA dosing make dose escalation potentially problematic. Our aim was to correlate AZA metabolite levels with therapeutic effects, toxicity, and adherence to medication in children with IMH and RAIH. Charts of 14 patients were retrospectively reviewed. The post-transplant diagnosis was based on liver biopsy and autoimmune markers. AZA was prescribed after establishing the post-transplant diagnosis. AZA was started at 1.1 (1.0,1.8) mg/kg/day. Routine biochemical studies, tacrolimus levels, 6-thioguanine (6-TG) and 6-methylmercaptopurine levels were assessed every 8 wk. AZA dose was routinely adjusted to achieve 6-TG levels between 235 and 450 pmol per 8 × 108 RBC. A total of 92 samples from 14 patients were reviewed. Four patients were excluded because of non-adherence. AZA dose was increased by 245% resulting in eight of 10 patients in the target range; no hepatic or bone marrow toxicity was observed. ALT levels and steroid requirements were significantly reduced (p < 0.05). The AZA dose required to achieve target 6-TG levels was significantly greater in children <10 yr. AZA metabolite testing in children post-liver transplant is useful in assessing adherence to medication and it is potentially helpful in optimizing medication dosing. In younger children the AZA dose requirements were two to four times higher than previously reported standard doses. [source]

Population pharmacokinetics of mycophenolic acid in children and young people undergoing blood or marrow and solid organ transplantation

BRITISH JOURNAL OF CLINICAL PHARMACOLOGY, Issue 4 2010
Lihua Zeng
WHAT IS ALREADY KNOWN ABOUT THIS PROJECT? , Mycophenolate mofetil (MMF) is an immunosuppressant drug used for the treatment and prevention of graft vs. host disease in blood or marrow transplantation and acute graft rejection in solid organ transplantation. , Mycophenolic acid (MPA) pharmacokinetics have not been thoroughly studied in paediatric blood or marrow transplant recipients and guidance for optimal dosing of mycophenolic acid in children is lacking. , Mycophenolic acid exhibits considerable inter- and intra-patient pharmacokinetic variability in adults and paediatric transplant recipients. , The AUC of mycophenolic acid over a 12 h dose interval at steady-state is generally agreed to be the most reliable metric associated with the risk of acute rejection. , Population pharmacokinetic analysis can utilize concentration information from both intensive sampling and sparse sampling to provide pharmacokinetic parameter estimates, estimates of inter- individual and intra-individual variability in these parameters and allows patient characteristics explaining inter-individual variability to be quantified. WHAT THIS STUDY ADDS , This study is one of the first investigations in which a population pharmacokinetic modelling approach was applied to assess the pharmacokinetics of both intravenous and oral MMF in children and young people undergoing blood or marrow and solid organ transplantation. , Bodyweight and concomitant ciclosporin were found to influence MPA pharmacokinetics. , This study evaluated current dosing strategies and found that they may be suboptimal for children weighing less than 10 kg. AIMS To characterize the population pharmacokinetics of mycophenolic acid (MPA) and evaluate dose regimens using a simulation approach and accepted therapeutic drug monitoring targets in children and young people undergoing blood or marrow, kidney and liver transplantation. METHODS MPA concentration,time data were collected using an age specific sampling protocol over 12 h. Some patients provided randomly timed but accurately recorded blood samples. Total and unbound MPA were measured by HPLC. NONMEM was employed to analyze MPA pharmacokinetic data. Simulations (n= 1000) were conducted to assess the suitability of the MPA dose regimens to maintain total MPA AUC(0,12 h) within the range 30 and 60 mg l,1 h associated with optimal outcome. RESULTS A two-compartment pharmacokinetic model with first-order elimination best described MPA concentration,time data. Population mean estimates of MPA clearance, inter-compartmental clearance, volumes of distribution in the central and peripheral compartments, absorption rate constant and bioavailability were 6.42 l h,1, 3.74 l h,1, 7.24 l, 16.8 l, 0.39 h,1 and 0.48, respectively. Inclusion of bodyweight and concomitant ciclosporin reduced the inter-individual variability in CL from 54.3% to 31.6%. Children with a bodyweight of 10 kg receiving standard MPA dose regimens achieve an MPA AUC below the target range suggesting they may be at a greater risk of acute rejection. CONCLUSIONS The population pharmacokinetic model for MPA can be used to explore dosing guidelines for safe and effective immunotherapy in children and young people undergoing transplantation.

Heart Failure Drug Utilization Patterns for Medicaid Patients Before and After a Heart Failure-Related Hospitalization

CONGESTIVE HEART FAILURE, Issue 3 2005
Patricia A. Howard PharmD
The authors examined heart failure (HF) drug utilization patterns in Medicaid patients before and after a HF-related hospitalization. This was a retrospective claims analysis of Kansas Medicaid beneficiaries hospitalized for HF between July 1, 2000, and March 31, 2001. HF drugs were tracked 6 months prior and 6 months following the admission. Angiotensin-converting enzyme (ACE) inhibitor doses were compared with target ranges. The cohort of 135 patients had a mean age of 53.6 years and was predominantly female (66.7%) and Caucasian (70.4%) with a high prevalence of cardiovascular comorbidities. Before hospitalization, less than one third of patients were receiving ACE inhibitors, angiotensin receptor blockers, , blockers, digoxin, or vasodilators. Following hospitalization, increased utilization was observed for , blockers, digoxin, and angiotensin receptor blockers, but overall usage remained low. ACE inhibitors and vasodilator use remained constant. ACE-inhibitor doses were below target ranges before and after hospitalization. In this Medicaid cohort, HF-related hospitalizations did not lead to improved HF therapy. [source]

Assessing postprandial glucose using 1,5-anhydroglucitol: An integrative literature review

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 10 2009
Brian Lee Christensen MS, CDE CDE-certified Diabetes Educator, FNP-BC
Abstract Purpose: Recent studies have determined postprandial blood glucose is an independent risk factor for macrovascular complications. This risk exists, despite having HbA1C results within acceptable ranges for diabetes. 1,5-Anhydroglucitol (1,5AG) has been proposed as an appropriate indicator to detect and screen for postprandial hyperglycemia (PPHG). This review discusses the efficacy of 1,5AG to predict PPHG in order to reveal those who may be at risk for macrovascular complications. Data Sources: An electronic search was conducted from 2003 to 2008 in the following databases: Medline, CINAHL, Health Source: Nursing/Academic Edition, and Pre-CINAHL. Any articles relating to 1,5AG as a marker for PPHG were used. The search was limited to any human research articles published in English. All articles were reviewed for additional relevant studies. Conclusions: 1,5AG was found to be a reliable indicator of PPHG, even when HbA1C levels were within target ranges. 1,5AG may be a simple and effective tool for primary care providers to identify those at risk for macrovascular complications, who would otherwise go unnoticed if assessed by HbA1C alone.

The quality of oral anticoagulant therapy and recurrent venous thrombotic events in the Leiden Thrombophilia Study

TOWARD CASE-BASED REASONING FOR DIABETES MANAGEMENT: A PRELIMINARY CLINICAL STUDY AND DECISION SUPPORT SYSTEM PROTOTYPE

COMPUTATIONAL INTELLIGENCE, Issue 3 2009
Cindy Marling
This paper presents a case-based decision support system prototype to assist patients with Type 1 diabetes on insulin pump therapy. These patients must vigilantly maintain blood glucose levels within prescribed target ranges to prevent serious disease complications, including blindness, neuropathy, and heart failure. Case-based reasoning (CBR) was selected for this domain because (a) existing guidelines for managing diabetes are general and must be tailored to individual patient needs; (b) physical and lifestyle factors combine to influence blood glucose levels; and (c) CBR has been successfully applied to the management of other long-term medical conditions. An institutional review board (IRB) approved preliminary clinical study, involving 20 patients, was conducted to assess the feasibility of providing case-based decision support for these patients. Fifty cases were compiled in a case library, situation assessment routines were encoded to detect common problems in blood glucose control, and retrieval metrics were developed to find the most relevant past cases for solving current problems. Preliminary results encourage continued research and work toward development of a practical tool for patients. [source]
