[Factors associated with dissatisfaction with pharmacological treatment in patients with type 2 diabetes mellitus: A cross-sectional study]

BACKGROUND AND OBJECTIVES

Diabetes is a chronic disease with a high impact on both health and Quality of Life Related to Health (QLRH). To evaluate the satisfaction of treatment in patients with type 2 diabetes mellitus through the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and its relationship with sociodemographic variables, with antidiabetic medication and clinical-analytical variables.

MATERIALS AND METHODS

This cross-sectional study was conducted in General University Hospital of San Juan de Alicante between September 2016 and December 2017. Two hundred thirty-two patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, treated with antidiabetic medication were included. The Spanish version of the DTSQ scale was used to measure satisfaction with treatment. Factors associated with low satisfaction were analyzed by applying the Chi-square test for qualitative variables and Student-T for quantitative variables. To estimate magnitudes of association, logistic models were adjusted.

RESULTS

Two hundred thirty-two patients were included in this study. 21.5% of the patients presented low satisfaction with the treatment. Patients who presented low satisfaction with treatment were associated with medications that could cause hypoglycemia (OR: 2.872 [1.195-6.903]), HbA1c levels higher than 7% (OR: 2.260 [1.005-5.083]) and drugs administered by the route oral (OR: 2.749 [1.233-6.131]).

CONCLUSIONS

Patients with type 2 diabetes mellitus who had a lower score on the DTSQ questionnaire were associated with medications that produced hypoglycaemia, and with higher levels of HbA1c higher than 7%, and those who took oral medication.

[Analysis of two health attendance models for the non-hospital emergencies in Gipuzkoa: Retrospective study]

BACKGROUND AND OBJECTIVE

Out-of-hospital medical emergency services are defined as a functional organization that performs a set of sequential human and material activities. The objective of this study was to compare the mortality of patients attended by the out-of-hospital medical emergency services in 2 neighboring Spanish regions with different models of healthcare transport assistance for emergency care.

MATERIAL AND METHOD

Retrospective observational cohort study, done between June 1, 2007 and December 31, 2008 in 2 regions of Gipuzkoa, Alto Deba (AD) and Bajo Deba (BD). The study variables were age, sex and place of exposure (AD/BD), heart rate, blood pressure, initial reason for the call defined by the European Resuscitation Council, unconsciousness and digestive bleeding. 3452 subjects were analyzed.

RESULTS

The risk of in situ mortality in BD was 1.31 times higher than in AD (P=.050), that of hospital mortality in BD was 0.71 times lower than in AD (P=.011) and the risk of mortality at one year between counties and the combined mortality (in situ+hospital) did not contribute significant differences.

CONCLUSIONS

Mortality (in situ+in-hospital, and one year aftercare) of patients treated by the out-of-hospital emergency medical services in AD (non-medicalized healthcare transport model) was similar to that of the BD region (mixed healthcare transport model).

HLA-G as a new tumor biomarker: detection of soluble isoforms of HLA-G in the serum and saliva of patients with colorectal cancer

INTRODUCTION

Recent medical investigations suggest that HLA-G, due to its tolerogenic properties, can be used as a biomarker in the diagnosis, treatment, and prognosis of different neoplasms. This observational prospective pilot study aims at detecting sHLA-G in the serum and saliva of patients diagnosed with colorectal cancer (CRC). For this purpose, we compared the expression of sHLA-G from patients with a control sample from a healthy population.

MATERIALS AND METHODS

Using the specific enzyme-linked immunosorbent assay (ELISA) method, the expression of sHLA-G in the serum and saliva samples from patients affected by CRC (n = 20) and in a control sample (n = 10) were analyzed.

RESULTS

The data showed that in patients with CRC, salivary sHLA-G values were significantly higher than in the control group (18.84 U/ml versus 6.3 U/ml, p = 0.036). In addition, higher levels of sHLA-G were observed in the saliva of patients with CRC in more advanced stages, compared with patients in early stages (24.2 U/ml vs. 8.1 U/ml, p = 0.019). A significant correlation was observed between the concentration of sHLA-G in the serum and saliva of the analyzed samples (Spearman correlation 0.7, p = 0.004).

CONCLUSIONS

This study demonstrates, for the first time, the possibility of detecting sHLA-G in the saliva of patients with CRC, resulting in a less invasive alternative to venipuncture. Likewise, we propose that sHLA-G could be an attractive molecular target based on its significant high levels in advanced stages.

[Tools to improve efficiency in the clinical management of hypertensive patients]

OBJECTIVE

To create a tool to evaluate the efficiency of the clinical management of hypertensive patients in Primary Care.

MATERIAL AND METHODS

A web-based questionnaire was designed for Primary Care centres to self-evaluate the management of hypertension in five specific areas: information systems, diagnostic and analytical tests, organisational aspects, use of resources, and continuous training programmes for patients and healthcare professionals. A committee of experts previously defined these questions and their ideal responses or "control", based on the scientific literature or, if there were no published references, by consensus of the committee. A descriptive analysis was performed on the data, and an adherence score was created that ranged from 0 (no adherence) to 1 (total adherence).

RESULTS

A total of 35 Primary Care centres entered their data into the website for the clinical management of hypertensive patients. The highest adherence to the ideal algorithm was observed in the area "Diagnostic and analytical tests" (0.69±0.10), and the lowest in "Continuous training programmes for patients and professionals" (0.42±0.21).

CONCLUSIONS

The efficiency of clinical management in hypertensive patients can be analysed using the website tool created for this purpose. Its use allows an internal audit to detect the areas that need improvement, and also serves to make comparative evaluations in the different areas of management over time.

Analysing the concept of diagnostic inertia in hypertension: a cross-sectional study

AIMS

The aim of this study was to quantify diagnostic inertia (DI) when the physician fails to diagnose hypertension and determine its associated factors.

METHODS

This cross-sectional, observational study involved all patients without a diagnosis of hypertension who had their blood pressure (BP) measured at least three times during the second half of 2010 (N = 48,605). Patients with altered mean BP figures (≥ 140/90 mmHg) were considered to experience DI. Secondary variables: gender, atrial fibrillation, diabetes mellitus, dyslipidemia, cardiovascular disease, age and the physician having attended a cardiovascular training course (ESCARVAL). Associated factors were assessed by multivariate logistic regression analysis.

RESULTS

Diagnostic inertia was present in 6450 patients (13.3%, 95% CI: 13.0-13.6%). Factors significantly associated with DI were: male gender (OR = 1.46, 95% CI: 1.37-1.55, p < 0.001), atrial fibrillation (OR = 0.73, 95% CI: 0.58-0.92, p = 0.007), the ESCARVAL cardiovascular course (OR = 0.88, 95% CI: 0.81-0.96, p = 0.005), diabetes mellitus (OR = 0.93, 95% CI: 0.87-0.99, p = 0.016), cardiovascular disease (OR = 0.77, 95% CI: 0.67-0.88, p < 0.001) and older age (years) (18-44→OR = 1; 45-59→OR = 12.45, 95% CI: 11.11-13.94; 60-74→OR = 18.11, 95% CI: 16.30-20.12; ≥ 75→OR = 20.43, 95% CI: 18.34-22.75; p < 0.001). The multivariate model had an area under the ROC curve of 0.81 (95% CI: 0.80-0.81, p < 0.001).

CONCLUSIONS

This study will help clinical researchers differentiate between the two forms of DI (interpretation of a positive screening test and interpretation of positive diagnostic criteria). The results found here in patients with hypertension suggest that this problem is prevalent, and that a set of associated factors can explain the outcome well (AUC>0.80).

Differences in the management of hypertension, diabetes mellitus and dyslipidemia between obesity classes

We did not find any paper that assessed clinical inertia in obese patients. Therefore, no paper has compared the clinical inertia rates between morbidly and nonmorbidly obese patients. A cross-sectional observational study was carried out. We analysed 8687 obese patients ⩾40 years of age who attended their health-care center for a checkup as part of a preventive program. The outcome was morbid obesity. Secondary variables were as follows: failure in the management of high blood pressure (HBP), high blood cholesterol (HBC) and high fasting blood glucose (HFBG); gender; personal history of hypertension, dyslipidemia, diabetes, smoking and cardiovascular disease; and age (years). We analysed the association between failures and morbid obesity by calculating the adjusted odds ratio (OR). Of 8687 obese patients, 421 had morbid obesity (4.8%, 95% confidence interval (CI): 4.4-5.3%). The prevalence rates for failures were as follows: HBP, 34.7%; HBC, 35.2%; and HFBG, 12.4%. Associated factors with morbid obesity related with failures were as follows: failure in the management of HBP (OR=1.42, 95% CI: 1.15-1.74, P=0.001); failure in the management of HBC (OR=0.73, 95% CI: 0.58-0.91, P=0.004); and failure in the management of HFBG (OR=2.24, 95% CI: 1.66-3.03, P<0.001). Morbidly obese patients faced worse management for HBP and HFBG, and better management for HBC. It would be interesting to integrate alarm systems to avoid this problem.

[Bibliometric analysis of International Scientific production on primary care]

OBJECTIVE

To present an international view of the scientific production in the field of primary care in the period 1985-2004.

DESIGN

Retrospective, observational study. Bibliometric analysis.

LOCATION

Medline database. WebSPIRS access through version 4.3. We analysed two periods: 2000-2004 (cross-sectional) and 1985-2004 (developmental). Search based on "MeSH Major" with descriptors: Primary Care or Primary Health Care, Family Practice, Family Physicians, Nurse Practitioners, and Entry Terms associated with these.

KEY MEASURES

We analysed the bibliometric indicators of production, circulation, dispersion, and visibility.

RESULTS

In 2000-2004, published 20911 articles were published, 0.73% of total production. There was a growth rate (1985-2004) of 221%, which was 2.4 times more than average. Transience rate was 83.17%. The English language is predominant (88.81%) over 34 languages, with Spanish being the next (2.6%). Sixteen countries produce 95.67% of the articles. Spain occupies the 7th place. Universities (52%) are the most productive institutions. There are 1074 different journals with the 10 most productive being: Br J Gen Pract, Adv Nurse Pract, Aust Fam Physician, Fam Pract, Fam Med, BMJ, Aten Primary Health Serv J, Can Fam Physician, J Fam Pract. The proportion of trials (5.43%) in PC is similar to other disciplines and has increased by 453% (1985-2004).

CONCLUSIONS

The production of Primary care is about 1% of the total scientific output, with a noticeable and higher than average growth over 20 years. The proportion of clinical trials is similar to other disciplines. Although Anglo-Saxon countries and journals are the highest producers, Spain and the journal Aten Primaria is among those highlighted.

[Evaluation of cardiovascular risk in the cross-sectional phase of the Mediterranean Study]

INTRODUCTION AND OBJECTIVES

The Mediterranean study quantifies high cardiovascular risk (HCR), consistency between REGICOR (R) and low risk SCORE (LS) scales, altered blood pressure (ABP) values in hypercholesterolemia (HC) without any history of hypertension (HT), high total cholesterol (HTC) values with HT with no background of HC and cardiac and renal damage in hypertensive patients.

PATIENTS AND METHODS

A national, cross-sectional and multicenter study was performed with the participation of 751 physicians. The physicians individually evaluated 7,973 patients with HT and 5,319 with HC. HCR was defined as over 10% with R and 5% with LS. Intra-class correlation coefficient (ICC) and Pearson coefficient (r) were calculated. The percentages of ABP and HTC were quantified. Creatinine (cr) value, glomerular filtration rate using Cockroft-Gault (CG), and prevalence of left ventricular hypertrophy (LVH) were analyzed.

RESULTS

Regarding hypertensive patients: 17.3% HCR with R and 26.1% with LS. ICC = 0.222 (p < 0.0001), r = 0.61 (p < 0.0001), 64.7% HTC. There was no evaluation of LVH in 31.2% and a prevalence of 5.1%, prevalence of lesion and kidney failure (KF) of 4.7% and 1.6% respectively based on CR and 15.9% KF by CG. In HC patients, there was 21.1% of HCR with R and 21.5% with LS; ICC = 0.190 (p < 0.0001), r = 0.64 (p < 0.0001) and 33.7% ABP.

CONCLUSIONS

The SCORE scale identifies more patients with HCR than the REGICOR one in HT patients and a similar amount in HC patients. Consistency between both scales is poor. A significant ABP/HTC was found. In HT patients, the patients who were not evaluated for LVH and the percentage of KF are important.

Screening for sight threatening diabetic retinopathy using non-mydriatic retinal camera in a primary care setting: to dilate or not to dilate?

OBJECTIVES

To evaluate three different strategies (without or with mydriasis) for community based screening for sight threatening diabetic retinopathy (STDR).

DESIGN

A masked cross-sectional comparative study.

SETTING

Primary care centre.

PARTICIPANTS

216 type-1 and type-2 diabetic patients (432 eyes).

INTERVENTIONS

Screening for STDR was performed with the Topcon CRW6S non-mydriatic camera (NMC), compared with the grading of the seven-field standard stereoscopic photographs, 30 degrees field photographs with mydriasis as the gold standard method. Three fields were studied: Field 1 centred on the macula; field 2 centred on the disc and the macula and field 3 centred on the disc, on the macula and temporal upper to the macula all without and with mydriasis.

MAIN OUTCOME MEASURES

Sensitivity and specificity of screening method and prevalence of STDR. Strategies: field 1 (macular), addition of field 2 (nasal), addition of field 3 (superior temporal) all without and with mydriasis.

RESULTS

The prevalence of STDR was 14.3%. When screening without mydriasis is performed, the percentage of referred patients increases from 14% (STDR) to almost 33% because of ungradable photographs. Sensitivity of detection of STDR by NMC using single field with mydriasis was 82% (95% confidence interval 72-92%) and without mydriasis 67% (54-80%). Specificity was 99% (97-100%) for single field with mydriasis and 99% (98-100%) without mydriasis. Sensitivity of detection using two fields with mydriasis was 95% (89-100%); without mydriasis (54-80%), slightly better than single field with mydriasis (72-92%). Specificity was similar.

CONCLUSIONS

Screening for STDR with NMC can be performed effectively with one non-stereoscopic retinal photograph per eye with mydriasis using tropicamide 0.5%. Screening without mydriasis increases the number of patients to be referred.

Control of diabetes and cardiovascular risk factors in patients with type 2 diabetes in primary care. The gap between guidelines and reality in Spain

To evaluate the level and factors affecting control of diabetes and cardiovascular risk factors in type 2 diabetes (TYPE 2 DM) patients. Multicentre cross-sectional study: a sample of 430 primary care practices across Spain selected 1907 type 2 diabetic patients. The first five consecutive ambulatory patients with TYPE 2 DM were eligible for the inclusion into the survey. Patients were free of known cardiovascular disease (CVD). Control criteria were defined based on 2002 American Diabetes Association (ADA) clinical practice recommendations. A total of 1907 patients (51% women) aged 63 +/- 9 years. Smoking prevalence was 22.6%, 50.6% had levels of A1c < 7%. Mean blood pressure (BP) was 148 +/- 17/86 +/- 10 mmHg. Only 7.8% have achieved the target of BP < 130/80 mmHg. Among the 1180 patients (65%) treated for hypertension, this target was attained in only 4.4% of patients. A measurement for low-density lipoprotein (LDL) cholesterol was available in 1669 patients (88%). Only 5.9% of patients achieved the target of LDL < 100 mg/dl. Among the 638 patients (41.6%) on drug treatment for dyslipidaemia, this target was attained in only 5.6% of patients. Among type 2 diabetic patients in Spain the prevalence of cardiovascular risk factors is high. Control of glycaemia, smoking, BP and LDL are far from optimal despite the widespread use of guidelines for the management of diabetes and CVD. The application of published recommendations needs to be reinforced.

[Inter-professional relationship between primary health care (PHC) and secondary care (hospital) in 1992 and 2000. A Delphi study]

AIM

To evaluate the trends in the inter-professional relationship between primary health care (PHC) and secondary care (hospital) at 2 different moments of the health reform, at its start in 1992 and after a phase of consolidation (2001).

DESIGN

Observational study based on modified Delphi technique.

SETTING

Valencia Community, Spain.

PARTICIPANTS

One hundred and ninety six professionals from Valencia Community were selected (103 PH centre administrators, 43 hospital and PC medical directors, and 50 heads of internal medicine or emergency services).

RESULTS

One hundred and ninety six questionnaires were sent out, with a response rate of 38%. In PHC problems remained the same, but the following got worse: "lack of motivation" (+1.34), "lack of overall vision of patients" (+1.10), and "overuse of medical services" (+1.06). The existence of non-integrated out-patient specialists got better (-1.32). In hospitals, "lack of overall vision of patients" got worse (+0.51), but in general problems got better, especially in "lack of communication and dialogue" (-1.14). PC increased its demand for "a single computerized clinical record" (+1.50), drawing up of common protocols (+0.86), and periodic rotations of PC doctors through hospitals (+0.85), but bureaucratic referrals to PC (-0.60) and the need for specialists in PC as consultants (-0.36) diminished. In hospitals all solutions showed lower scores, particularly access of PC doctors to monitoring of admitted patients (-2.44) and PC doctors doing hospital cover (-2.30).

CONCLUSIONS

Problems and solutions from PHC and hospitals remain the same, but there is a trend to the worse in PHC, whereas in hospitals the trend is more positive.

[Validity of clinical records and information systems in studies of health-care delivery in primary care]

OBJECTIVES

To examine how well the clinical process was recorded in the clinical history (CH), and care delivery on the activity sheet (AS). To assemble a series of recommendations on the validity of these documents for recording health care delivery.

DESIGN

Multi-centred, observational, and cross-sectonal study.

SETTING

Four medical clinics at 12 health centres in the Community of Valencia, Spain.

PARTICIPANTS

There were 2051 attendances, with 284 CH and 407 AS involved. Main measurements and results. The information recorded by doctors in the CH and on the AS was validated by external observers who collected directly at the consultation the working day's entire care activity. The following was analysed: 1) in the CH, filling out of the "SOAP" form (basic info.); 2) on the AS, mean per professional per day of scheduled and on-demand patients, home visits and length of consultations; 3) information in the documents validated on the organisation of consultations; 4) analysis of care delivery according to how predictable it is and its clinical content; 5) clinical practice guidelines with validity and clinical usefulness indicators and reliability index (kappa).

CONCLUSIONS

The documents validated do not properly reflect the reality of health care demand. There was an under-recording bias and validity problems that may limit their usefulness as sources of information for health care planning and management.
