Family Physician Clinical Inertia in Managing Hypoglycemia

AimsClinical inertia behaviour affects family physicians managing chronic disease such as diabetes. Literature addressing clinical inertia in the management of hypoglycemia is scarce. The objectives of this study were to create a measurement for physician clinical inertia in managing hypoglycemia (ClinInert_InHypoDM), and to determine physicians’ characteristics associated with clinical inertia.MethodsThe study was a secondary analysis of data provided by family physicians from the InHypo-DM Study, applying exploratory factor analysis. Principal axis factoring with an Oblimin rotation was employed to detect underlying factors associated with physician behaviors. Multiple linear regression was used to determine association between the ClinInert_InHypoDM scores and physician characteristics.ResultsFactor analysis identified a statistically sound 12-item one-factor scale for clinical inertia behavior. No statistically significant differences in clinical inertia score for the studied independent variables were found.ConclusionsThis study provides a scale for assessing clinical inertia in the management of hypoglycemia. Further testing this scale in other family physician populations will provide deeper understanding about the characteristics and factors that influence clinical inertia. The knowledge derived from better understanding clinical inertia in primary care has potential to improve outcomes for patients with diabetes.     

Elevated Serum Cytokines and Trichomonas vaginalis Serology at Diagnosis Are Not Associated With Higher Gleason Grade or Lethal Prostate Cancer

Background

Inflammation and infections have been associated with prostate cancer progression. We assessed whether elevated serum cytokines or T. vaginalis seropositivity at the time of diagnosis was associated with higher grade or lethal prostate cancer.

儿童精神分裂症患者的预后及相关因素分析

目的探讨儿童精神分裂症的预后及其影响因素。方法收集1987—1997年首次住院的儿童(起病年龄≤14岁)精神分裂症患者(儿童组)124例和同期首次住院的成人(起病年龄25～30岁)精神分裂症患者(成人组)120例,采用社会功能缺陷量表(SDSS)、日常生活能力量表(ADL)、大体评定量表(GAS)及自制调查表,以随访与量表现场测评相结合的方法获得资料,数据采用多因素回归分析。结果(1)儿童组服药依从性(90例,77.6%)好于成人组(73例,64.0%；)χ~2= 5.11,P＜0.05)；复发率(29.3%)低于成人组(42.1%；χ~2=4.10,P＜0.05)。(2)儿童组预后良好者(91例,78.4%)显著多于成人组(65例,57.0%)。(3)儿童组的社会功能[(2.11±1.02)分]和日常生活能力[(18.78±9.17)分]优于成人组[(3.48±1.86)分和(21.82±8.67)分；P＜0.01和P＜0.05]。(4)经多因素回归分析,影响儿童精神分裂症预后的主要因素有：社会家庭关爱程度,首次住院疗效,起病形式,服药时间和病期(P＜0.01)。结论儿童精神分裂症患者总体预后较好；充分的家庭关爱,首次住院疗效好,急性起病,坚持长期治疗和病期较短者的预后更好。     

应用秩和比法研究门诊人数增长与门诊医疗质量因子的关系

目的研究医院门诊人数增长与门诊医疗质量因子的关系,找出影响门诊人数增长的主要门诊医疗质量因子。方法利用秩和比法对实例进行分析。结果影响门诊人数增长的门诊质量因子,首先是高中级职称比(χ2=32.43,P<0.05),其次是副高以上职称的坐诊工时比(χ2=31.91,P<0.05),再次是新技术项目或重大改革(χ2=28.54,P>0.05)。结论研究医院门诊人数增长与门诊医疗质量因子的关系时,秩和比法有应用推广的价值。

尿激酶溶栓对急性心肌梗死患者单核细胞组织因子表达的影响

目的 :了解冠心病患者外周循环单核细胞组织因子 (TF)表达与冠心病病情的关系 ;观察溶栓治疗对急性心肌梗死患者单核细胞TF表达的影响。方法 :测定了 2 2例稳定型心绞痛 (SA)患者 ,2 1例不稳定型心绞痛(UA)患者 ,1 5例急性心肌梗死 (AMI)患者用尿激酶溶栓前及溶栓后 ,1 8例健康人外周循环单核细胞组织因子阳性率。单核细胞组织因子阳性率测定用免疫荧光染色及流式细胞术。结果 :SAP组 ,UAP组和AMI组单核细胞TF阳性率高于对照组 ,UAP组和AMI组单核细胞TF阳性率高于SAP组 ,单核细胞TF阳性率与冠心病病情显著相关。急性心肌梗死患者溶栓后 2h单核细胞TF阳性率升高。结论 :外周血单核细胞TF的表达与冠心病病情严重程度密切相关 ;急性心肌梗死患者溶栓治疗后单核细胞TF的表达进一步增强 ,这可能是溶栓后凝血酶活化的原因之一。
