Economic advantage of a community-based malaria management program in the Brazilian Amazon.
(49/1125)
In the Brazilian Amazon, travel costs to centralized malaria clinics for diagnosis and treatment can approach 20% of one's monthly salary. A program was established in a mining town for community-based dipstick test diagnosis and treatment. An economic analysis was performed that compared expected costs under the old program to the observed costs of the new one. Data were obtained through interviews, government reports, clinic and hospital records, and community records. There was a 53% reduction (by 1,219 visits) of clinic visits but a doubling of malaria hospitalization admissions (to 191). The new program had an overall annual savings of $60,900 ($11.8K-$160K, sensitivity limits), a 77% reduction of the old program's cost. The benefit-to-cost ratio was 9:1, where benefits were patients' savings from travel and lost wages and costs were government drug, diagnostic, training, and monitoring expenses. A community-based program incorporating dipstick tests for malaria management can have economic advantages. (+info)
A computer based intervention on the appropriate use of arterial blood gas.
(50/1125)
OBJECTIVE: To evaluate impact of a computer-based intervention on arterial blood gas (ABG) usage in an intensive care setting. DESIGN: Retrospectively examined, via mixed group analysis, the effects of the intervention on ABG usage in the intensive care unit (ICU). SUBJECTS: Included all clinicians who placed ABG orders in an ICU using the computerized physician order-entry system, as well as controls in non-order entry units. METHODS: Computer-based intervention presenting ordering clinician with patient s previous ABG values and limiting forward duration of tests ordered. Study spanned 12 weeks, 5 weeks pre-intervention and 7-weeks post-intervention. Of 8 ICUs, intervention implemented in 6, not implemented in 2. Data analyzed using the repeated measure ANOVA. RESULTS: Physicians entered <40% ABG orders. 376 ABGs per week processed pre-intervention, 387 per week post. Results nonsignificant with a p= 0.09. Orders placed declined from 1039 per week, Jan 2000 to 662 per week, April 2001. DISCUSSION: Study did not demonstrate significant change; limited power. Need longer study periods. Impact improved in the future by targeting physician users and tailoring intervention to specific work flow pattern of high utilization units. (+info)
Women who are recalled for further investigation for breast screening: psychological consequences 3 years after recall and factors affecting re-attendance.
(51/1125)
BACKGROUND: In 1995-1996 a study was commenced investigating the experience of 'false-positive' women, i.e. who had undergone further investigations following routine breast screening and received a clear final result. These women were found to experience significantly greater adverse psychological consequences at 1 month, 5 months and 11 months after assessment compared with women who received a clear result after the initial basic mammogram. The present study follows up these 'false-positive' women 3 years later (at 35 months) just before being invited for their next routine breast screening. It investigates the effect of the previous experience of breast screening on adverse psychological consequences reported by false-positive women at this time, and explores factors that may be associated with the current adverse psychological consequences. Factors influencing attendance for the forthcoming appointment are reported, and the non-attendance rate is monitored. METHODS: Women who had previously completed a questionnaire 1 month, 5 months and 11 months after their last breast screening 3 years ago, were invited to complete a postal questionnaire just before being invited to attend for their next routine mammogram 3 years later. Attendance for this appointment was monitored. A brief questionnaire was sent to non-attenders to ascertain their reasons for not attending. RESULTS: The response rate was 77 per cent (387/505). Women who, at their last routine breast screening, had received a clear result after fine needle aspiration (FNA) at assessment, after a surgical biopsy or after a 6 month early recall appointment, all suffered significantly greater adverse psychological consequences at 1 month before returning for routine breast screening 3 years later than women who had received a clear result after the initial mammogram at their last routine breast screening. They were between 1.7 and 2 times more likely to suffer psychological consequences than women who received a clear result after their last mammogram. Women who had received a clear result at assessment without undergoing FNA reported higher psychological consequences than those who received a clear result after mammography, but the difference was not significant (relative risk 1.28, 95 per cent confidence interval 0.82-2.00). Fifteen per cent of those who had undergone assessment 3 years earlier did not attend their next routine breast screening appointment compared with 8 per cent of those who received a clear result after mammography (p = 0.035). Factors associated with adverse psychological consequences are reported. CONCLUSION: Despite having received a final clear result during their previous routine breast screening 3 years ago, women who had undergone FNA, surgical biopsy or been placed on early recall suffered significantly greater adverse psychological consequences at 1 month before their next routine breast screening appointment than women who had received a clear result after their initial mammogram at their last routine breast screening. Having undergone further investigations did not necessarily motivate women to attend for their next routine appointment, with 15 per cent of these women not returning for routine screening 3 years on.

Routine ultrasound screening in diabetic pregnancies.
(52/1125)
OBJECTIVES: To assess the detection rate of congenital fetal malformations and specific problems related to routine ultrasound screening in women with pre-existing diabetes. METHODS: A retrospective study was carried out to assess the performance of routine ultrasound screening in women with pre-existing diabetes (Types 1 and 2) within a tertiary institution. The incidence, type and risk factors for congenital fetal malformations were determined. The detection rate of fetal anomalies for diabetic women was compared with that for the low-risk population. Factors affecting these detection rates were evaluated. RESULTS: During the study period, 12 169 low-risk pregnant women and 130 women with pre-existing diabetes had routine ultrasound screening performed within the institution. A total of 10 major anomalies (7.7%) and three minor anomalies (2.3%) were present in the fetuses of the diabetic women. Central nervous system and cardiovascular system anomalies accounted for 60% of the major anomalies. Periconceptional hemoglobin A1c of more than 9% was associated with a high prevalence of major anomalies (143/1000). Women who had fetuses with major anomalies had a significantly higher incidence of obesity (78% vs. 37%; P < 0.05). Ultrasound examination of these diabetic pregnancies showed high incidences of suboptimal image quality (37%), incomplete examinations, and repeat examinations (17%). Compared to the 'low-risk' non-diabetic population from the same institution, the relative risk for a major congenital anomaly among the diabetic women was 5.9-fold higher (95% confidence interval, 2.9-11.9). The detection rate for major fetal anomalies was significantly lower for diabetic women (30% vs. 73%; P < 0.01), and the mean body mass index for the diabetic group was significantly higher (29 vs. 23 kg/m2; P < 0.001). CONCLUSION: The incidence of congenital anomalies is higher in diabetic pregnancies. Unfortunately, the detection rate for fetal anomalies by antenatal ultrasound scan was significantly worse than that for the low-risk population. This is likely to be related to the maternal body habitus and unsatisfactory examinations. Methods to overcome these difficulties are discussed. (+info)
Improvement of information gained from the pre-anaesthetic visit through a quality-assurance programme.
(53/1125)
BACKGROUND: Pre-anaesthetic evaluation is a fundamental component of anaesthetic practice. The aims of the present study were to assess the quality of the preoperative anaesthetic information gathered and to observe the quality profile after the introduction of a standardized form. This occurred through a four-step quality assurance programme over a 4-yr period. METHODS: The proportion of cases in which a complete recording of data was collected at the preoperative assessment was evaluated by searching in each patient's medical record for what was considered to be the minimum information required to provide satisfactory perioperative care. Fifteen criteria were selected. The recovery profile for each indicator and a global quality index (GQI expressed in %) for each patient's record were collected. In phase 1, the existing situation was assessed. Next, a standardized pre-anaesthetic form (PAF 1) was designed and its implementation evaluated (Phase 2). Phase 3 was performed 16 months after implementation of PAF 1 to assess the long-term value. The form was revised (PAF 2) and its use evaluated again 6 months later (Phase 4). For each evaluation, the records of a 1-month period were examined. Overall 1129 medical records were audited. RESULTS: The GQI increased significantly from 62 to 88% with similar changes for both elective and emergency cases. The recovery profile was improved for most indicators. CONCLUSIONS: We conclude that the quality of information recorded from the pre-anaesthetic visit is improved by using a standardized form. This will hopefully help to improve patient outcome and facilitate computerization of the anaesthetic record. (+info)
Development and maintenance of a community-based hepatitis C registry.
(54/1125)
OBJECTIVE: To develop a model for community-population- or health system-based registries of all patients with diagnosed hepatitis C, to facilitate clinical care and epidemiologic studies. STUDY DESIGN: Geographically defined, population-based cohort study. METHODS: Registry subjects were identified using January 1, 1990, to December 31, 1999, data from the Rochester Epidemiology Project (REP), which lists all diagnoses for Olmsted County residents recorded by clinicians during visits to Olmsted County medical providers. We supplemented diagnostic data with information from laboratory databases that record all hepatitis C testing in Olmsted County. All diagnoses based on the REP and laboratory databases were confirmed by medical record review. Proposed data elements to be included in a hepatitis C registry were identified and defined, and data collection methodology was tested. RESULTS: A total of 355 subjects (62% male) were identified in the total community population of 130,000. Both the diagnostic summary database (n = 309, 87%) and the laboratory database (n = 46, 133%) were important in the identification of subjects for the registry. Nine additional subjects with diagnostic or laboratory evidence of hepatitis C refused the legislatively mandated (Minnesota statute) medical records research authorization and could not be included in the registry. Most desired data elements were available in the medical records. CONCLUSIONS: Both medical visit diagnostic summaries (administrative or billing data) and laboratory databases are required to identify subjects with physician-based diagnoses of hepatitis C. Few patients refused the authorization required for inclusion in a research registry. (+info)
Papanicolaou test use among reproductive-age women at high risk for cervical cancer: analyses of the 1995 National Survey of Family Growth.
(55/1125)
OBJECTIVES: This study assessed the relationship between risk factors for cervical cancer and Papanicolaou (Pap) test use within the past year among reproductive-age women. METHODS: The 1995 National Survey of Family Growth, a demographic and reproductive health survey of 10 847 women aged 15 to 44, was analyzed with multiple logistic regression. RESULTS: Of the women, 62% reported having had a Pap test within the past year. Use was significantly higher among women with risk factors and among African American women. Use was significantly lower among uninsured, poor, and foreign-born women and among women with lower educational attainment and of "other" race/ethnicity. CONCLUSIONS: Strategies to improve Pap test use include (1) educational campaigns that inform women of cervical cancer risk factors and encourage screening and (2) increased support for programs that expand access to Pap tests.

Cost of routine screening for carotid and lower extremity occlusive disease in patients with abdominal aortic aneurysms.
(56/1125)
OBJECTIVE: The burden of clinically relevant noncoronary atherosclerotic occlusive disease in patients with abdominal aortic aneurysms (AAAs) is poorly defined. Furthermore, the cost-effectiveness of routine versus selective preoperative noninvasive examination of the carotid and lower extremity arterial beds has not been established in patients who undergo elective AAA repair. METHODS: Diagnostic vascular laboratory study results were reviewed in 206 patients who underwent evaluation before AAA repair from 1994 to 1998. The patients underwent routine preoperative carotid duplex scan examinations and lower extremity Doppler scan arterial studies with ankle-brachial index (ABI) determinations. The medical records were reviewed for the identification of clinical evidence consistent with cerebrovascular or lower extremity arterial occlusive disease. The costs of routine screening and selective screening were determined with Medicare reimbursement schedules. RESULTS: The prevalence rate of advanced (80% to 100%) carotid artery stenosis (CAS) was 3.4%, and 18% of the patients had CAS between 60% and 100%. Advanced peripheral vascular occlusive disease (PVOD; ABI, <0.3) was found in 3% of the patients, and 12% of the patients had an ABI of less than 0.6. Most patients with advanced CAS (71%) or advanced PVOD (83%) had clinical indications of their disease. The absence of clinical evidence of disease had a negative predictive value of 99% for both advanced CAS and PVOD. The cost of routine screening for all patients for advanced CAS was $5445 per case. Routine screening for severe PVOD costs were $3732 per case discovered. In contrast, the costs for selective screening for advanced CAS or PVOD in patients with appropriate history or symptoms were $1258 and $785 per case found, respectively. CONCLUSION: Routine noninvasive diagnostic testing for the identification of asymptomatic CAS and PVOD in patients with AAA may not be justified. Preoperative screening is more clearly indicated for patients with AAAs who have clinical evidence suggestive of CAS or PVOD. (+info)
