RESUMO

Few studies have identified the metabolic consequences of the post-acute phase of nonsevere COVID-19. This prospective study examined metabolic outcomes and associated factors in nonsevere, RT-PCR-confirmed COVID-19. The participants' metabolic parameters, the prevalence of long-term multiple metabolic abnormalities (≥ 2 components), and factors influencing the prevalence were assessed at 1, 3, and 6 months post-onset. Six hundred individuals (mean age 45.5 ± 14.5 years, 61.7% female, 38% high-risk individuals) with nonsevere COVID-19 attended at least one follow-up visit. The prevalence of worsening metabolic abnormalities was 26.0% for BMI, 43.2% for glucose, 40.5% for LDL-c, 19.1% for liver, and 14.8% for C-reactive protein. Except for lipids, metabolic-component abnormalities were more prevalent in high-risk hosts than in healthy individuals. The prevalence of multiple metabolic abnormalities at the 6-month follow-up was 41.3% and significantly higher in high-risk than healthy hosts (49.2% vs 36.5%; P = 0.007). Factors independently associated with a lower risk of these abnormalities were being female, having dyslipidemia, and receiving at least 3 doses of the COVID-19 vaccine. These findings suggest that multiple metabolic abnormalities are the long-term consequences of COVID-19. For both high-risk and healthy individuals with nonsevere COVID-19, healthcare providers should monitor metabolic profiles, encourage healthy behaviors, and ensure complete vaccination.

RESUMO

The dynamics of humoral immune responses of patients after SARS-CoV-2 infection is unclear. This study prospectively observed changes in anti-receptor binding domain immunoglobulin G (anti-RBD IgG) and neutralizing antibodies against the Wuhan and Delta strains at 1, 3, and 6 months postinfection between October 2021 and May 2022. Demographic data, clinical characteristics, baseline parameters, and blood samples of participants were collected. Of 5059 SARS-CoV-2 infected adult patients, only 600 underwent assessment at least once between 3 and 6 months after symptom onset. Patients were categorized as immunocompetent (n = 566), immunocompromised (n = 14), or reinfected (n = 20). A booster dose of a COVID-19 vaccine was strongly associated with maintained or increased COVID-19 antibody levels. The booster dose was also more strongly associated with antibody responses than the primary vaccination series. Among patients receiving a booster dose of a mRNA vaccine or a heterologous regimen, antibody levels remained steady or even increased for 3 to 6 months after symptom onset compared with inactivated or viral vector vaccines. There was a strong correlation between anti-RBD IgG and neutralizing antibodies against the Delta variant. This study is relevant to resource-limited countries for administering COVID-19 vaccines 3 to 6 months after infection.

RESUMO

BACKGROUND: The efficacy of mobile stroke units (MSUs) in improving acute ischemic stroke (AIS) care in developing countries is unknown. We compared performance measures and stroke outcomes in AIS patients between MSU and usual care: emergency medical services (EMS) and walk-in. METHODS: We enrolled patients > 18 years of age with an AIS within 4.5 h after onset. Demographic data, types, and time of reperfusion therapies and clinical outcomes were recorded. A favorable outcome was defined as a modified Rankin Scale (mRS) 0-2 at 3 months. RESULTS: A total of 978 AIS patients (MSU = 243, EMS = 214, walk-in = 521) were enrolled between June 1, 2018, and April 30, 2021. The mean age (± SD) was 66 (± 14) years, and 510 (52.1%) were male. AIS time metrics were the shortest in the MSU with a mean (± SD) door to needle (DN) time of 20 (± 7), 29 (± 13), and 35 (± 16) min (p < 0.001) and door to puncture (DP) time of 73 ± 19, 86 ± 33, and 101 ± 42 min (p < 0.001) in MSU, EMS, and walk-in, respectively. Participants in the MSU (56.8%) received higher rate of reperfusion therapie(s) when compared to the EMS (51.4%) and walk-in (31.5%) (p < 0.001). After adjustment for any potential confounders and using the EMS as a reference, the MSU has the highest likelihood of achieving a favorable outcome (adjusted OR 2.15; 95% CI 1.39-3.32). CONCLUSIONS: In underserved populations, MSUs significantly reduced DN time, increased the likelihood of receiving reperfusion treatment, and achieved independency at 3 months when compared to usual care.

RESUMO

This study aimed to evaluate the efficacy of early antiviral treatment in preventing clinical deterioration in asymptomatic or mildly symptomatic severe acute respiratory syndrome coronavirus 2 infected (COVID-19) patients in home isolation and to share our experiences with the ambulatory management of nonsevere COVID-19 patients. This retrospective study included mild COVID-19 adult patients confirmed by real-time reverse transcription-polymerase chain reaction. They received care via an ambulatory management strategy between July 2021 and November 2021. Demographic data, clinical progression, and outcomes were collected. Both descriptive and inferential statistics were performed to illustrate the cohort's characteristic and outcomes of the study. Univariable and multivariable logistic regression models were employed to investigate the associations between clinical factors and disease progression. A total of 1940 patients in the Siriraj home isolation system met the inclusion criteria. Their mean age was 42.1 ±â€…14.9 years, with 14.2% older than 60 years, 54.3% female, and 7.1% with a body weight ≥ 90 kg. Only 115 patients (5.9%) had deterioration of clinical symptoms. Two-thirds of these could be managed at home by dexamethasone treatment under physician supervision; however, 38 of the 115 patients (2.0% of the study cohort) needed hospitalization. Early favipiravir outpatient treatment (≤ 5 days from onset of symptoms) in nonsevere COVID-19 patients was significantly associated with a lower rate of symptom deterioration than late favipiravir treatment (50 [4.6%] vs 65 [7.5%] patients, respectively; P = .008; odds ratio 1.669; 95% confidence interval, 1.141-2.441). The unfavorable prognostic factors for symptom deterioration were advanced age, body weight ≥ 90 kg, unvaccinated status, higher reverse transcription-polymerase chain reaction cycle threshold, and late favipiravir treatment. The early delivery of essential treatment, including antiviral and supervisory dexamethasone, to ambulatory nonsevere COVID-19 patients yielded favorable outcomes during the COVID-19 pandemic in Thailand.

RESUMO

This study aimed to assess the clinical characteristics of patients who registered at the Siriraj Favipiravir Clinic and to share our experiences in this comparatively unique clinical setting. This retrospective study included patients who registered at the Siriraj Favipiravir Clinic during August 11, 2021 to September 14, 2021. Included adult patients were those with severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) infection confirmed by antigen test kit (ATK) or real-time reverse transcription-polymerase chain reaction, no favipiravir contraindication, no prior COVID-19 treatment, and not receiving care from another medical facility. Demographic data and outcomes were collected and analyzed. Of the 1168 patients (mean age: 44.8 ± 16.4 years, 55.7% female) who registered at the clinic, 117 (10%) did not meet the treatment criteria, and 141 (12%) patients did not pick up their medication. One-third of patients had at least 1 symptom that indicated severe disease. Higher proportion of unvaccinated status (56.7% vs 47.5%, P = .005), higher proportion of persons with risk factors for disease progression (37.7% vs 31.3%, P = .028), and longer duration between the date of clinic registration and the date of positive diagnostic test (3 vs 2 days, P = .004) were significantly more commonly observed in the severe disease group compared to the nonsevere disease group. The duration between symptom onset and the date of clinic registration was significantly longer in the real-time reverse transcription-polymerase chain reaction group than in the ATK group (6 vs 4 days, P < .001). Most patients (90.0%) had completed favipiravir treatment regimen. The improvement and mortality rates were 86.7% and 1.2%, respectively. COVID-19 severity is associated with vaccination status, baseline risk factors, and timing between disease detection and treatment. The use of ATK influences patients to seek treatment significantly earlier in ambulatory setting. Our early diagnosis and antiviral treatment strategy yielded favorable results in an outpatient setting during a COVID-19 outbreak in Thailand.

RESUMO

AIMS/INTRODUCTION: The Thai Type 1 Diabetes and Diabetes Diagnosed Before Age 30 Years Registry, Care and Network was established in 2014 and involved 31 hospitals. The objective of the registry was to evaluate glycemic control and complications of patients with type 1 diabetes. MATERIALS AND METHODS: Patients' demographics, clinical data, frequencies of daily self-monitoring of blood glucose (SMBG), glycemic control and complications were collected. RESULTS: Among the 1,907 type 1 diabetes patients, the mean age was 21.2 ± 11.3 years. The mean glycated hemoglobin level was 9.35 ± 2.41%, with significant variations among age groups (P < 0.001). Conventional insulin treatment and intensive insulin treatment were used in 43 and 57% of patients, respectively. Mean glycated hemoglobin levels were significantly higher in patients treated with conventional insulin treatment compared to those treated with intensive insulin treatment (9.63 ± 2.34 vs 9.17 ± 2.46%, P = 0.002). Compared to the conventional insulin treatment group, significantly more patients in the intensive insulin treatment group achieved good glycemic control (P < 0.001), and fewer had diabetic retinopathy (P = 0.031). The prevalence of microvascular complications increased significantly with age (P < 0.001). Multivariate analysis showed good glycemic control to be associated with age 25 to <45 years, intensive insulin treatment with SMBG three or more times daily and diabetes duration of 1 to <5 years. CONCLUSIONS: Most Thai type 1 diabetes patients were not meeting the recommended glycemic target. As a result of this study, the national program to improve the quality of diabetes treatment and education has been implemented, and the results are ongoing.

RESUMO

OBJECTIVE: To assess the cost effectiveness of an initial ICU admissionforpatients with severe sepsis or those in septic shock following the initial resuscitation in the emergency department. MATERIAL AND METHOD: Mortality data was generated through retrospective data obtained from 1,048 adult patients with severe sepsis or in septic shock from one tertiary care and eight community hospitals in Phitsanulok during the period of October 2010 to September 2011. These patients were categorized into two groups; as either admitted from the emergency department directly to the ICU (stated as an immediate ICU admission) or admitted from the emergency department to the general hospital ward due to an unavailability of lCU beds (stated as a delayed ICU admission). The overall direct costs and characteristics were simulated from a second group of 994 adult patients, admitted a year later from selected data by the ICD-10 codes [International Classification of Diseases, 10th edition] with the same conditions of severe sepsis and septic shock (September 2011 through September 2012), as there was no collection of costs and characteristics during the first period (October 2010 through September 2011). A decision tree model and an incremental cost-effectiveness ratio (ICER) were used for the analyses of the cost-effectiveness. RESULTS: There were no significant differences in either the mean ages or lengths of stay between both groups. All-cause mortality rates have shown an incidence of 22.2% for the immediate ICU admission group and an incidence of 46.3% in the delayed ICUadmission group (odds ratio for the immediate ICU admission group was 0. 479 with a 95% confidence interval, 0.376-0.611). Total costs (mean, 95% CI) of the immediate ICUadmission group [37,194 baht (32,389-44,926)] were higher than had been seen in the delayed ICU admission group [26,275 (24,300-27,936)]. Incremental cost was 10,919 baht. ICER for the immediate ICU admission group was 45,307 baht per life saved. CONCLUSION: Immediate ICU admission for patients with severe sepsis or in septic shock following the initial resuscitation in the emergency department has shown a satisfactory cost-effectiveness profile in low-to-middle income countries.

RESUMO

BACKGROUND: Diabetes mellitus is one of the most common diseases in the Thai population, and it is well known that diabetic complications could be prevented with appropriate management. Despite published guidelines, most Thai patients with diabetes do not achieve treatment goals. Siriraj Continuity of Care clinic (CC clinic) was recently established in order to provide training for medical students and internal medicine residents. It is possible that the training component in the CC clinic may contribute to better overall outcomes in type 2 diabetes mellitus (type 2 DM) patients when compared with usual care at the medical out-patient department (OPD). OBJECTIVE: To compare the effectiveness of diabetic management in type 2 diabetes mellitus patients who attended the CC clinic and the medical OPD. MATERIAL AND METHOD: Retrospective chart review was performed in type 2 diabetes mellitus patients who were treated at either clinic at Siriraj Hospital in 2007-2011. Baseline demographics, treatment strategies and outcomes, and participation in an appropriate health maintenance program were assessed in both groups. RESULTS: Seven hundred and fifty seven medical records were reviewed, including 383 patients in the CC clinic group and 374 in the OPD group. Mean HbA1c was significantly lower in the CC clinic group compared with the OPD group (7.3 +/- 0.9% and 7.8 +/- 1.3%, respectively, < 0.001). The number of patients who achieved goal HbA1c of less than 7% in CC clinic group was 123 (32.1%) compared with 91 (24.3%) in the OPD group (p = 0.039). More patients were screened for diabetic complications in the CC clinic group compared with the OPD group, including screening for diabetic neuropathy (57.4% vs. 2.1%, p < 0.001), diabetic retinopathy (56.7% vs. 36.6%, p < 0.001), and diabetic nephropathy (80.9% vs. 36.9%, p < 0.001). Patients in the CC clinic group had a higher rate of age-appropriate cancer screening than those in the OPD group (54.2% vs. 13.3%, p < 0.001 for breast cancer; 24.0% vs. 0.9%, p < 0.001 for cervical cancer; and 23.0% vs. 7.4%, p < 0.001 for colon cancer). Moreover, significantly more patients in the CC clinic group received recommended immunization (influenza, diphtheria tetanus and pneumococcal vaccine) compared with the control group (p < or = 0.001). CONCLUSION: Diabetic patients treated at the CC clinic had better clinical outcomes and healthcare maintenance compared with those who received usual care at the medical OPD. Continuity of care and integrated training component may have contributed to the improved outcomes.

RESUMO

OBJECTIVE: To compare the cost utility of using erythropoietin (EPO) to maintain different hemoglobin (Hb) target levels in hemodialysis patients from a societal perspective. METHODS: A Markov model was used to estimate the incremental cost and quality-adjusted life-year of five Hb levels: 9 or less, more than 9 to 10, more than 10 to 11, more than 11 to 12, and more than 12 g/dl. A systematic review of EPO treatment in hemodialysis patients was conducted to estimate transitional probabilities. Cost data were estimated on the basis of the reference price of Siriraj Hospital, the largest university hospital in Thailand. Utility scores were derived from the six-dimensional health state short form (derived from short-form 36 health survey), which were collected from 152 hemodialysis patients receiving EPO at Siriraj hospital. Probabilistic sensitivity analysis was conducted to investigate the effect of uncertain parameters. All future costs and outcomes were discounted at the rate of 3% per annum. RESULTS: The incremental cost-effectiveness ratios of Hb levels more than 9 to 10, more than 10 to 11, more than 11 to 12, and more than 12 g/dl compared with the least costly option (Hb ≤ 9 g/dl) were US $24,128.03, US $18,789.07, US $22,427.36, and US $28,022.33 per quality-adjusted life-year, respectively. From probabilistic sensitivity analysis, the hemoglobin level of more than 10 to 11 g/dl was appropriate when the willingness to pay was US $15,523.88 to US $46,610.17 and the probability of cost-effective was 29.32% to 95.94%. CONCLUSIONS: Providing EPO for a hemoglobin level of more than 10 to 11 g/dl had a cost-effectiveness higher than that of doing so for other hemoglobin levels. This finding will be put forward to the policy level to set up the EPO treatment guideline of the hospital for hemodialysis patients.

RESUMO

OBJECTIVE: To evaluate cost-effectiveness analysis of 18F-FDG PET/CT to detect tumor recurrence or metastasis in well-differentiated thyroid cancer patients with high Tg but negative TBS in Thailand. MATERIAL AND METHOD: A retrospective literature review of 55 studies published between 1978 and 2010 was done. Decision analysis by TreeAge program showed an evaluation of the most cost-effective treatment and 18F-FDG PET/CT scan in thyroid cancer patients with high Tg but negative TBS. The incremental cost and life years gained associated with seven strategies approached were analyzed by the decision tree model. The first strategy was treatment with empirical high dose 131I therapy. The second to the seventh strategies were using imaging investigations by CT scan of neck and chest, 99mTc MIBI scan, and 18F-FDG PET/CT scan to identify recurrent, persistent, and metastatic lesions before the specific treatment via curative surgery, external radiotherapy, and high dose 131I therapy. All strategies were adopted using hospital perspective and direct medical cost was estimated based on the reference price of Siriraj Hospital. Deterministic sensitivity analysis was conducted to investigate the effect of the cost of PET/CT scan. RESULTS: The strategy using 18F-FDG PET/CT scan to detect recurrence or metastasis and possible curative surgery in operable cases and high dose 131I therapy in inoperable cases gave the highest life years gained of 27.08 with cost of 90,227.61 Baht (2,926.24 US dollars) and acceptable incremental cost effectiveness ratio (ICER) of 6,936.88 Baht (224.98 US dollars) per life year gained when compared to the least costly strategy using 99mTc MIBI scan and additional 18F-FDG PET/CT scan in negative MIBI result. Other strategies were dominated by this PET/CT strategy. Deterministic sensitivity analysis (based on the willingness to pay (WTP) 360,000 Baht (11,675.42 US dollars) showed that the cost of PET/CT scan has no impact on the net health benefit. CONCLUSION: Based on the hospital perspective, the cost-effectiveness of 18F-FDG PET/CT scan in detecting suspected recurrence or metastasis in thyroid carcinoma patients with negative diagnostic TBS but high Tg was first done using 18F-FDG PET/CT scan to identify disease, followed by curative surgery or high dose 131I therapy. Moreover cost of PET/CT scan did not influence the net health benefit. This PET/CT benefit is helpfulfor considering the proper PET/CT use for thyroid cancer in Thailand.

RESUMO

BACKGROUND: Many diabetic patients did not receive proper medical care to achieve treatment goals based on clinical practice recommendations. Siriraj Continuity of Care clinic (CC clinic) has been established specifically for medical students and internal medicine residency training purpose since 2006. The training components in the teaching clinic might contribute to overall better outcomes for Type 2 diabetic patients comparing to regular service clinics. OBJECTIVE: To evaluate the efficacy of Siriraj CC clinic curriculum on improving clinical outcomes of diabetic patients. MATERIAL AND METHOD: The authors retrospectively reviewed medical records of type 2 diabetic patients who had been referred from regular service clinics of Siriraj Out-Patient Department (OPD) to CC clinic during 2007 to 2011. Clinical outcomes of these patients were compared: before vs. after entering CC clinic. RESULTS: One hundred and eighty medical records were reviewed. The mean of HbA1c were 7.5 and 7.3 percent before and after entering CC clinic (p = 0.026). Comparing clinical outcomes before vs. after entering CC clinic, we found that the percentage of patients who had optimal BMI and who had achieved LDL goals were 16.3 vs. 21.6 (p = 0.021), and 56.7 vs. 73.1 (p = 0.001), respectively. The proportion of patients who received annual diabetic complication assessments were also higher after entering CC clinic: the percentage of patients who received examinations of the eye, had urine micro albumin checked, had been screened for diabetic foot were increased from 58.3 to 93.3 (p < 0.001), 35.6 to 83.9 (p < 0.001), and 6.7 to 91.1 (p < 0.001), respectively. Moreover there were more patients who received adult health care maintenance program including: cancer screening program (clinical breast examination, mammography, fecal occult blood test and pap smear) and immunization (influenza, diphtheria tetanus and pneumococcal vaccine) (p < 0.001) after entering CC clinic. CONCLUSION: After entering CC clinic, diabetic patients had better clinical outcomes as well as received better screening and health care maintenance program comparing to regular service clinics. The focus training components in this clinic has played a major role on contributing the preferred clinical performance among medical students and internal medicine residents.

RESUMO

PURPOSES: Quality of life assessment in obstructive sleep-disordered breathing (OSDB) is increasingly recognized, and the functional outcomes of sleep questionnaire (FOSQ) is a popular instrument. The objective of this study was to apply this questionnaire in Thai patients to assess its reliability, validity, and responsiveness properties. METHODS: A total of 223 subjects were recruited. The scores of FOSQ in 38 healthy volunteers and 40 primary snorers were compared with those of 108 obstructive sleep apnea (OSA) patients diagnosed by polysomnography. Seventy-two subjects answered the FOSQ twice at 2-4 weeks apart to check the test-retest reliability, and 37 patients with OSA who complied well with CPAP therapy answered them again after treatment at 3-6 months. All participants also filled the Epworth sleepiness scales (ESS) to check the concurrent validity. RESULTS: There were statistically significant differences in all FOSQ subscales including global scores between healthy volunteers (17.3 ± 2.1) and OSA patients (14.5 ± 2.9) (p < 0.001). The internal consistency of the questionnaire was excellent (Cronbach's alpha 0.95), and the test-retest reliability (intra-class correlation coefficients) was 0.70 in global scores. After adequate CPAP therapy, all FOSQ scores increased significantly (p < 0.001) There were significant correlations between all FOSQ scores except sexual relationship and ESS (r -0.48); however, these had only a weak relationship with AHI and minimal oxygen saturation. CONCLUSIONS: The FOSQ can be applied to Thai patients with OSDB with good reliability, validity, and responsiveness properties. It may be the first validated version of FOSQ in East Asian countries which is a very useful tool for future research.

RESUMO

OBJECTIVE: To compare the efficacy and cost-effectiveness of high and low dose regimens of I-131 treatment in patients with hyperthyroidism. MATERIAL AND METHOD: One hundred fifty patients with proven hyperthyroidism were randomly allocated into the high (74 patients) and low (76 patients) dose regimen of I-131 treatment. Four patients of the high dose group and one patient of the low dose group were excluded because of lost follow-up. A gland-specific dosage was calculated on the estimated weight of thyroid gland and 24-hour I-131 uptake. The high and low I-131 dose regimens were 150 microCi/gm and 100 microCi/gm, respectively. The first mean radioiodine activity administered to the high and low dose group was 10.2 and 8 mCi, respectively. Repeated treatment was given to 25 patients of the high dose group and 40 patients of the low dose group. Clinical outcome and calculated costs for outpatient attendances, and laboratory tests together with initial and subsequent treatments were evaluated for one year after I-131 treatment. Elimination of hyperthyroidism that resulted in either euthyroidism or hypothyroidism was classified as therapeutic success. The cost effectiveness was also compared. RESULTS: At 6 months after treatment, 45 (64.3%) patients receiving high dose and 59 (78.7%) patients receiving low dose were hyperthyroidism. Clinical outcome at one year showed persistence of hyperthyroidism in 21 (30%) patients of the high dose regimen and 36 (48%) patients of the low dose regimen. At one year post treatment, it was demonstrated that the high dose regimen could eliminate hyperthyroidism in a significantly shorter time than the low dose regimen, i.e., 259.6 days and 305.5 days, respectively, p = 0.008). For the persistent hyperthyroid patients, the average total cost of treatment in the low dose group was significantly higher than that of the high dose group, i.e., 13,422.78 baht and 10,942.79 baht, respectively; p = 0.050). CONCLUSION: A high dose regimen of radioactive iodine treatment is more effective than the low dose regimen. The successful outcome of a high dose regimen occurred significantly earlier than that of the low dose regimen. For the persistent hyperthyroid patients, the average total cost in the low dose group was significantly higher than that of the high dose group.

RESUMO

PURPOSES: The objectives of this study are to test the reliability and validity of the Thai version of the Epworth sleepiness scale (ESS) and to assess the relationship between the ESS score and the severity of obstructive sleep disordered breathing. METHODS: A total of 228 subjects (149 males and 79 females) were recruited. In order to check the discriminant validity of the ESS, we included 32 healthy volunteers and 39 patients with primary snoring to be the control groups and 126 patients with obstructive sleep apnea (OSA) confirmed by full polysomnography to be the disease groups. The test-retest reliability was investigated in 71 subjects. To check the responsiveness properties of the questionnaire, we asked a separate group of 31 patients who were successfully treated with either continuous positive airway pressure (CPAP) or upper airway surgery to complete the ESS before and after treatment at 3-6 months. RESULTS: The internal consistency demonstrated by Cronbach's alpha coefficients for standardized item was 0.87 and a range from 0.84 to 0.86 if some items were deleted. The test-retest reliability was shown by intra-class correlation coefficients of 0.79. There was a statistically significant difference between the mean of the ESS scores of the control groups (6.1 ± 3.0) and the OSA patients (9.9 ± 5.3) (p < 0.001). The ESS scores decreased significantly after a successful treatment with both CPAP and surgery (p < 0.001); however, there was no statistically significant difference among different severities of OSA. CONCLUSIONS: Our Thai version of the ESS showed an excellent internal consistency and test-retest reliability. It is able to discriminate between control subjects and OSA patients and to assess the response of treatment; however, it has a weak relationship with the apnea-hypopnea index. Therefore, we recommend use it to combine with more comprehensive clinical evaluation in obstructive sleep disordered breathing patients.

RESUMO

BACKGROUND: The continuity of care clinic (CCC) curriculum has been added to final-year medical students, class of 2008. The goals were to improve cardiovascular risk management skills for medical students and to develop competent doctors to serve the public. OBJECTIVE: To study the effectiveness of the curriculum by directly comparing postgraduate patient care performance between CCC participants (class of 2008) and non-CCC participants (class of 2006 and 2007). MATERIAL AND METHOD: We collected information about both groups of graduates, when they started their doctor careers. With hospitals'permission, medical charts audits were performed and scored with a 12-task checklist of cardiovascular risk management. The scores from both groups were compared with statistical analyses. RESULTS: Among 266 charts from 17 hospitals, there were 123 charts from 38 CCC participants and 143 charts from 52 non-CCC participants. On 9 of 12 tasks of the checklist, proportionately more CCC participants carried out the tasks than non-CCC participants. Statistical significance was shown on 5 tasks. These were ability to properly adjust antihypertensive medication (13.4% more; p = 0.002); requesting for urine protein screening (12.1% more; p = 0.006); recommending life-style modification (24.9% more; p < 0.001); requesting for serum lipid profile (25.5% more; p < 0.001); prescribing aspirin as primary prevention for cardiovascular disease (13.1% more; p = 0.007). There was no statistically significant difference for the other 7 tasks. CONCLUSION: Cardiovascular risk management performance of CCC participants was better than non-CCC participants in the same period after graduations. The curriculum helped improve the cardiovascular risks management skill of postgraduates. In the public interest, this study recommends further implementation of such a program in the future.

RESUMO

BACKGROUND: Despite the scanty data, proton pump inhibitors (PPI) are widely used for stress-related mucosal disease (SRMD) prophylaxis. There were few studies using PPI for SRMD prophylaxis but the results were conflicting, most probably due to inadequate sample size. The present meta-analysis aimed to determine the efficacy of PPI, as compared to histamine-2 receptor antagonists (H2RA) in the prevention of SRMD in critically-ill patients. MATERIAL AND METHOD: Meta-analysis of the randomized controlled trials comparing PPI versus H2RA for SRMD prophylaxis was performed. Outcomes of interest were incidences of clinically important gastrointestinal bleeding and nosocomial pneumonia. RESULTS: Three studies involving 569 patients were included in the meta-analysis. The overall incidence of clinically important bleeding was significantly lower in the PPI group (3.5%) as compared to H2RA (8%), odds ratio (OR) 0.42 (95% CI 0.20-0.91). The incidences of nosocomial pneumonia were not different (10.2% versus 10.1%, OR 1.02, 95% CI 0.59-1.75) between the two groups. CONCLUSION: The use of PPI for SRMD prophylaxis was associated with a significantly lower rate of clinically important bleeding than H2RA with similar rates of nosocomial pneumonia.

RESUMO

BACKGROUND: Obstructive sleep apnea (OSA) increases the risk for mild hypertension, but its relationship to refractory hypertension (RHT) has not been systematically examined. We previously reported a high prevalence of OSA in patients with RHT, but did not have a control group with which to compare. Rapid eye movement (REM) sleep deprivation can raise blood pressure in animals. However, a potential relationship of OSA and REM sleep time with RHT has not been examined. OBJECTIVE: To determine whether, compared with patients with well controlled hypertension, those with RHT have a higher prevalence of OSA (apnea-hypopnea index > or = 10 per hour of sleep) and shorter REM sleep time. METHODS: We compared the prevalence of OSA and sleep structure in 42 patients with RHT with 22 patients with controlled hypertension, matched for age, sex and BMI. RESULTS: Compared with the controlled hypertension group, the RHT group had a significantly higher prevalence of OSA (81 versus 55%, P = 0.03) and less REM sleep time (47.0 +/- 4.5 versus 63.2 +/- 4.9 min, P = 0.02). Multivariate analysis revealed significantly increased odds of having RHT associated with OSA independent of other risk factors (adjusted odds ratio, 3.994; 95% confidence interval, 1.191-13.388). Reduced REM sleep time was also independently associated with the presence of RHT (adjusted odds ratio, 1.025; 95% confidence interval, 1.002-1.049). CONCLUSION: OSA and reduced REM sleep time are associated with increased odds of having RHT and, therefore, may play roles in its pathogenesis.

RESUMO

OBJECTIVE: To evaluate the efficacy of the acute ST segment elevation treatment guidelines in reducing the door-to-balloon time at Siriraj Hospital. MATERIAL AND METHOD: Retrospective analysis of the data and records obtained from one hundred and twenty eight patients who underwent primary percutaneous intervention for acute ST segment elevation myocardial infarction at Siriraj Hospital between June 2002 and February 2006. Control chart analysis was applied to evaluate the efficacy of the guidelines. RESULTS: The mean door-to-balloon time was consistently reduced from 243.23 minutes before to 137.13 minutes after the guidelines implementation. Control chart analysis showed that this reduction in door-to-balloon time reached statistical significance. CONCLUSION: The guidelines developed by a multidisciplinary approach could effectively reduce the door-to-balloon time.

RESUMO

OBJECTIVE: Although a common procedure, nasogastric (NG) intubation is also painful and unsatisfactory. Previous studies showed the benefits of local anesthesia in various forms over lubricant jelly alone, but they are rarely used due to their inconvenience and unavailability. The authors conducted a double-blind randomized controlled study to compare a commercial-available 10% lidocaine spray plus 2% lidocaine jelly lubrication and 2% lidocaine jelly lubrication alone prior to NG intubation. MATERIAL AND METHOD: Patients who fulfilled the indications for NG intubation were randomized to receive either 10% lidocaine spray or placebo (normal saline) spray to the nostril and throat prior to NG intubation. NG tubes lubricated with 2% lidocaine jelly were then inserted by experienced physicians. Physician, who sprayed, inserted the NG tubes and collected the patient's data, did not know the content of the spray, while patients were also blinded against the information of the spray. RESULTS: Sixty patients were included in the present study. Thirty one randomly received lidocaine spray and 29 received placebo spray. There were more female patients in the lidocaine group (65% vs. 28%, p=0.04), but ages, indications for NG intubation, size of NG tube, and physicians' experience in the procedure were similar in both groups. Patients' discomfort after being sprayed was also similar in both groups. However during the NG intubation, the patients in the lidocaine group experienced less pain as measured by visual analog scale (23.6 +/- 16.6 vs. 43.1 +/- 31.4 mm, p=0.005) and less discomfort (30.0 +/- 24.4 vs. 51.4 +/- 30.0 mm, p=0.004) than the placebo group. Ninety-three percent of the patients in the lidocaine group favored the same spray for their next intubations, while 65% of the placebo group did (p = 0.009). In addition, there was more physicians' satisfaction in the lidocaine group as measured by 5-point Likert scale (p=0.041). Likewise, 61% of the physicians favored lidocaine spray compared to 34.5% of the placebo spray (p=0.038). Degree of difficulty, duration of intubation, number of attempts and success rates of NG intubations were as well similar in both groups. No complications were found in the present study. CONCLUSION: 10% lidocaine spray plus 2% lidocaine jelly lubrication was more effective in relieving patients' pain, discomfort, and resulted in higher physicians' satisfaction. There were also no additional side effects as compared to 2% lidocaine jelly lubrication alone. Therefore, it should be recommended for routine application.

RESUMO

OBJECTIVE: Postoperative endophthalmitis reflects in part quality and safety aspects of cataract surgery. Preoperative 5% povidone-iodine was introduced as a quality improvement effort. This study evaluated the effect of this additional measure on the occurrence of endophthalmitis after cataract surgery. METHOD: Topical 5% povidone-iodine solution was applied onto the ocular surface just prior to transferring the patient into the operative theater for cataract surgery. Other prophylactic measures were allowed to continue as before. Patients developing postoperative intraocular inflammation and undergoing intravitreal antibiotic injection were included as occurrences of endophthalmitis. Alteration in endophthalmitis rate was analyzed using a 'p control chart' of a statistical process control method. The incidence in the povidone-iodine-receiving group was compared to those before implementation and concurrent nonreceiving groups. RESULT: The postoperative endophthalmitis rate showed a significant reduction after introduction of povidone-iodine. A year before, 9 of 3,052 eyes developed endophthalmitis (0.294%). After introduction, this occurred in 4 of 4,089 eyes receiving povidone-iodine (0.097%) and 1 of 502 nonreceiving eyes (0.199%) in the following 16 months. Despite the apparent lower rate, comparison between groups was not statistically significant. Moderate to severe but tolerable eye irritation after application was reported in 6.6%. No other adverse events were detected. CONCLUSION: Topical preoperative 5% povidone-iodine contributed an additional effect to the reduction of the postoperative endophthalmitis rate after cataract surgery. This measure was rather safe to apply as a prophylaxis against endophthalmitis in cataract surgery.
