Variability in the detection and monitoring of chronic patients in primary care according to what is registered in the electronic health record.

BACKGROUND: The electronic health record (EHR) allows a detailed study of the primary care consultations and assessment of variability among physicians regarding the implementation of practices for prevention, detection and monitoring of chronic diseases. OBJECTIVES: To describe the variability in the detection and surveillance of chronic conditions in primary care. METHODS: Review of the medical records maintained by 1685 primary care physicians in the Basque Health Service. Estimation of age and sex standardized rates of compliance with evidence-based recommendations and the systematic component of variation (SCV). RESULTS: Compliance with screening recommendations varied from 14.2% for chronic obstructive pulmonary disease (COPD) to 37.2% for hypercholesterolaemia of the at-risk populations. Variability between Primary Care Units (PCUs) was low (SCV(5) (-95) < 0.10) for high blood pressure, hypercholesterolaemia and diabetes and high (SCV(5) (-95) ≥ 0.20) for COPD. Based on the EHR registries, recommendations were followed to in at least 50% of relevant patients according to only 10 of the 44 good care practice (GCP) criteria. For 16 of the GCP criteria, the EHR data indicated compliance to the recommendations in <25% of patients diagnosed. CONCLUSIONS: EHR data indicate that some of the preventative care practices recommended to detect chronic problems in primary care are unevenly implemented across PCUs. Notably, there is less variation in the case of conditions for which evidence-based clinical practice guidelines have been published. The level of monitoring is inadequate for all the conditions studied; particularly in those in which it is less evident that primary care is the right level of the health service to provide this care.

Variability of indication criteria in knee and hip replacement: an observational study.

BACKGROUND: Total knee (TKR) and hip (THR) replacement (arthroplasty) are effective surgical procedures that relieve pain, improve patients' quality of life and increase functional capacity. Studies on variations in medical practice usually place the indications for performing these procedures to be highly variable, because surgeons appear to follow different criteria when recommending surgery in patients with different severity levels. We therefore proposed a study to evaluate inter-hospital variability in arthroplasty indication. METHODS: The pre-surgical condition of 1603 patients included was compared by their personal characteristics, clinical situation and self-perceived health status. Patients were asked to complete two health-related quality of life questionnaires: the generic SF-12 (Short Form) and the specific WOMAC (Western Ontario and Mcmaster Universities) scale. The type of patient undergoing primary arthroplasty was similar in the 15 different hospitals evaluated.The variability in baseline WOMAC score between hospitals in THR and TKR indication was described by range, mean and standard deviation (SD), mean and standard deviation weighted by the number of procedures at each hospital, high/low ratio or extremal quotient (EQ5-95), variation coefficient (CV5-95) and weighted variation coefficient (WCV5-95) for 5-95 percentile range. The variability in subjective and objective signs was evaluated using median, range and WCV5-95. The appropriateness of the procedures performed was calculated using a specific threshold proposed by Quintana et al for assessing pain and functional capacity. RESULTS: The variability expressed as WCV5-95 was very low, between 0.05 and 0.11 for all three dimensions on WOMAC scale for both types of procedure in all participating hospitals. The variability in the physical and mental SF-12 components was very low for both types of procedure (0.08 and 0.07 for hip and 0.03 and 0.07 for knee surgery patients). However, a moderate-high variability was detected in subjective-objective signs. Among all the surgeries performed, approximately a quarter of them could be considered to be inappropriate. CONCLUSIONS: A greater inter-hospital variability was observed for objective than for subjective signs for both procedures, suggesting that the differences in clinical criteria followed by surgeons when indicating arthroplasty are the main responsible factors for the variation in surgery rates.

[Population-based cross sectional study about vaccine acceptability and perception of the severity of A/H1N1 influenza: opinion of the general population and health professionals]. / Estudio transversal basado en la población sobre la aceptabilidad de la vacuna y la percepción de la gravedad de la gripe A/H1N1: opinión de la población general y de los profesionales sanitarios.

OBJECTIVES: To determine the intention of general population and health professionals to vaccinate against the H1N1 influenza A virus. To determine the perception of severity of the H1N1 influenza A in both groups compared to that of seasonal influenza. METHODS: Cross-sectional telephone survey performed to a sample of population (obtained randomly from the Vitoria-Gasteiz telephone directory) and cross-sectional electronically-administered survey to a sample of health professionals from public health centres in Vitoria-Gasteiz, conducted between 6th and 16th November 2009. The relative and absolute frecuency of persons willing to be vaccinated and the proportion of those considering the H1N1 influenza A as a life-threatening risk were calculated in both groups. RESULTS: 219 (33%) persons out of 637 contacted telephone numbers answered the questionnaire, as well as 109 health professionals. 63.0% (n=138) of general population and 73.4% (n=80) of the professional group would not undergo vaccination, even if it was for free (p=0.595). If belonging to a high-risk group, the corresponding proportions of unwillingness were 14.6% (n=32) for general population and 40.4 (n=44) for professionals (p<0.001). The proportion of undecided persons is 25.6% (n=56) in general population, against 6.4% (n=7) among the professionals. CONCLUSIONS: At the beginning of the vaccination campaign, the majority of population is unwilling to undergo immunization against the H1N1 influenza A virus. The proportion in general population is similar to that among the health professionals. However, when belonging to a high-risk group, there is a high proportion of undecided persons in general population.
