Logistic Regression Analysis and Nursing Interventions for High-risk Factors for Pressure Sores in Patients in a Surgical Intensive Care Unit

Objective： To investigate the risk factors related to the development of pressure sores in critically ill surgical patients and to establish a basis for the formulation of effective precautions. Methods： A questionnaire regarding the factors for pressure sores in critically ill surgical patients was created using a case control study with reference to the pertinent literature. After being exam- ined and validated by experts, the questionnaire was used to collect data about critically ill surgical patients in a grade A tertiary hospital. Among the 47 patients enrolled into the study, the 14 who developed nosocomial pressure sores were allocated to the pressure sore group, and the remaining 33 patients who met the inclusion criteria and did not exhibit pressure sores were allocated to the control group. Univariate and multivariate logistic regression analyses were employed to examine the differences in 22 indicators between the two groups in an attempt to identify the risk factors for pressure sores. Results： According to the univariate analyses, the maximum value of lactic acid in the arterial blood, the number of days of norepinephrine use, the number of days of mechanical ventilation, the number of days of blood purification, and the number of days of bowel incontinence were statistically greater in the pressure sore group than in the control group （P〈0.05）. The multivariate logistic regression analysis revealed that the number of days of norepinephrine use and the level of lactic acid in the arterial blood were high risk-factors for pressure sores （P〈0.05）. Conclusions： The best method for preventing and control pressure sores in surgical critically ill patients is to strongly emphasize the duration of the critical status and to give special attention to patients in a continuous state of shock. The adoption of measures specific to high-risk patient groups and risk factors, including the active control of primary diseases and the application of decompression measures during the treatment of the patients, are helpful for improving the quality of care in the prevention and control of pressure sores in critically ill patients.

Newborn Umbilical Cord Care in Parakou in 2013: Practices and Risks

Objective: The objective was to study umbilical care practices and risks in Parakou (North Benin). Patients and method: It was a cross-sectional and descriptive study carried out within a community from June 1 to August 31, 2013. It focused on all the infants born at the maternity of Parakou Health Center and their mothers. Results: Two hundred and ten newborns were included i.e. 101 boys and 109 girls. In 80.9% of cases, inappropriate substances had been applied to umbilical cord. Umbilical cord care quality was adjudged as poor, acceptable and good in 58.6%, 31.9% and 9.5% of cases respectively. A bacterial umbilical infection had been noted in 59.5% of newborns. Only 4.8% had sterile umbilical wound. The commonest bacteria were: Staphylococcus aureus (58.1%), Staphylococcus saprophiticus (53.3%), Escherichia coli (44.8%) and Pseudomonas aeruginosa (14.3%). The factors associated with umbilical infection were: low educational status of mother (p = 0.026), low-income occupation of mother (p = 0.021), customary practices to accelerate umbilical cord fall off (p = 0.007), short time to cord falling off lower than 6 days (p = 0.015). Conclusion: Umbilical cord care involves high risk for bacterial infection in our context. Strong actions must be taken within the community in order to reduce that risk.

Risk Factors Associated with Acinetobacter baumannii Infections in Patients in an Intensive Care Unit of a Public Hospital in Paraná

To identify risk factors for A. baumannii infection in patients hospitalized in an Intensive Care Unit (ICU) of a tertiary public hospital in Paraná, Brazil, a retrospective paired case-control study (ratio 1:2) was conducted from January 2018 to December 2020. Patients in the case group were hospitalized in the ICU with A. baumanni (n = 68 cases) and were compared with patients in the control group, without infection by A. baumannii (n = 136). Both were matched by age (±10 years), sex, and ICU stay (±5 days). Conditional multiple logistic regression was used to determine statistically significant risk factors based on the results of bivariate analyses. Mortality was higher in infected (cases) than in non-infected patients (51.5% vs. 39.7%). The incidence and bacterial resistance increased annually. At bivariate analysis, cases had longer hospital stays (median 35 vs. 22 days, p A. baumannii and antimicrobial resistance. There is need for surveillance, and constant evaluation of control actions. Risk factors were colonization, previous hospitalization, and hospitalization time. This is essential for the decision-making of professionals and optimization of prevention, control, and therapeutic management actions.

Risk factors and antibiotic resistance of pneumonia caused by multidrug resistant Acinetobacter baumannii in pediatric intensive care unit

With beta-lactam drugs and immunosuppressants widely used, the infection caused by Acinetobacter baumannfi （Ab） has become more and more serious with multidrug resistant Acinetobacter baumannfi （MDRAb） emerging and worsening rapidly. Compared with other patients, the incidence and multidrug resistance of MDRAb are higher in children in pediatric intensive care unit （PICU） because of immune deficiency, severe basic diseases, prolonged hospitalization and invasive operations. Hence it is significant to study the epidemiology and changes of antibacterial susceptibility in order to reduce the incidence of MDRAb in children. A total 115 patients with MDRAb pneumonia and 45 patients with negative MDRAb （NMDRAb） pneumonia who had been treated from January 2009 to August 2011 were studied retrospectively at the PICU of Wuhan Children＇s Hospital. Clinical data were analyzed with univariate and multivariate Logistic regression. In 176 clinical strains of Acinetobacter baumannfi isolated, there were 128 strains of MDRAb, accounting for 72.73%. Drug susceptibility tests showed that the resistance rates of 13-1actam antibiotics were more than 70% except for cefoperazone sulbactam. The rates to carbapenems were higher than 90%. They were significantly higher than those of NMDRAb. Amikacin, levofloxacin, ciprofloxacin and minocycline had the lowest drug-resistance rates （〈20%）. Multivariate Logistic regression revealed that ICU stay, the time of mechanical ventilation, anemia, hypoproteinemia and the use of carbapenems were independent risk factors for MDRAb pneumonia. MDRAb is an important opportunistic pathogen to pneumonia in PICU, and its drug-resistance is severe. It increases significantly the mortality of patients. It is important to take the effective prevention measures for controlling it.

Why Are Risk-Pooling and Risk-Sharing Arrangements Necessary for Financing Healthcare and Improving Health Outcomes in Low and Lower Middle-Income Countries

Health is important to economic development, and economic development has an important impact on health outcomes. Health Expenditure makes up a substantial part of the global economy. In the world, the costs of healthcare are increasing;patients are compelled to pay more for treatment, and that makes a lot of people faced to Catastrophic Health Expenditures (CHE) and in long run fall below the poverty line. One of the most urgent and vexing challenges faced by many low- and middle-income countries is how to provide health care for the more than two billion poor people who live in these areas (developing countries). As much as more than 65% (in 2014) of total private health care expenditure in low-income countries comes from out-of-pocket payment by patients. In addition, according to World Bank report (2007), in low and lower middle-income countries was speared nearly 13% of global health spending with 87% the global disease burden. The WHO considers health financing models with high risk pooled, such as health insurance and prepaid schemes, a promising means for achieving universal health-care coverage and promotion health care. A crucial concept in health financing is that of pooling. The WHO defines risk-pooling as the “accumulation and management of revenues in such a way as to ensure that the risk of having to pay for health care is borne by all members of the pool and not by each contributor individually”. The larger degree of pooling, the less people will have to bear the health financial risks. Furthermore, adopting and operating financing policies based on greeter risk pooling/sharing (prepayments) are recommended to all countries (especially in low and lower-middle income countries). It means risk sharing/pooling plays a key role in all financing systems for achieving effectiveness and efficiency health systems.

Prevention of stress-related ulcer bleeding at the intensive care unit: Risks and benefits of stress ulcer prophylaxis

Stress-related mucosal disease is a typical complication of critically ill patients in the intensive care unit(ICU). It poses a risk of clinically relevant upper gastrointestinal(GI) bleeding. Therefore, stress ulcer prophylaxis(SUP)is recommended in high-risk patients, especially those mechanically ventilated > 48 h and those with a manifest coagulopathy. Proton pump inhibitors(PPI) and, less effectively, histamine 2 receptor antagonists(H2RA) prevent GI bleeding in critically ill patients in the ICU. However, the routine use of pharmacological SUP does not reduce overall mortality in ICU patients. Moreover, recent studies revealed that SUP in the ICU might be associated with potential harm such as an increased risk of infectious complications, especially nosocomial pneumonia and Clostridium difficile-associated diarrhea. Additionally, special populations such as patients with liver cirrhosis may even have an increased mortality rate if treated with PPI. Likewise, PPI can be toxic for both the liver and the bone marrow, and some PPI show clinically relevant interactions with important other drugs like clopidogrel. Therefore, the agent of choice, the specific balance of risks and benefits for individual patients as well as the possible dose of PPI has to be chosen carefully. Alternatives to PPI prophylaxis include H2 RA and/or sucralfate. Instead of routine SUP, further trials should investigate risk-adjusted algorithms, balancing benefits and threats of SUP medication in the ICU.

Depression risk in patients with coronary heart disease in Germany

AIM To determine the prevalence of depression and its risk factors among patients with coronary heart disease(CHD) treated in German primary care practices.METHODS Longitudinal data from nationwide general practices in Germany(n = 1072) were analyzed.Individuals initially diagnosed with CHD(2009-2013) were identified,and 59992 patients were included and matched(1:1) to 59992 controls.The primary outcome measure was an initial diagnosis of depression within five years after the index date among patients with and without CHD.Cox proportional hazards models were used to adjust for confounders.RESULTS Mean age was equal to 68.0 years(SD = 11.3).A total of 55.9% of patients were men.After a five-year follow-up,21.8% of the CHD group and 14.2% of the control group were diagnosed with depression(P < 0.001).In the multivariate regression model,CHD was a strong risk factor for developing depression(HR =1.54,95%CI:1.49-1.59,P < 0.001).Prior depressive episodes,dementia,and eight other chronic conditions were associated with a higher risk of developing depression.Interestingly,older patients and women were also more likely to be diagnosed with depression compared with younger patients and men,respectively.CONCLUSION The risk of depression is significantly increased among patients with CHD compared with patients without CHD treated in primary care practices in Germany.CHD patients should be routinely screened for depression to ensure improved treatment and management.

Pattern of mental health service use and risk of injury: A longitudinal study

Objective: The aim of this study is to investigate the association between mental health treatment patterns and risk of injuries among a Western Australian male birth cohort. Method: A population-based birth-cohort of males born between 1980 and 1984 in Western Australia was followed up using linked health data. Results: Participants with mental health conditions were at an increased risk of injury. Those with a continuous mental health treatment pattern without interruption or window periods had lower risk of injury compared to those with treatment interruption or window periods. The adjusted incidence rate ratios (95% confidence interval) for injury among participants: 1) without a mental condition, 2) with a previous mental condition, 3) with a mental condition in the last four years and without interruption in their mental health treatment, and 4) with a mental condition in the last four years with interruptions in mental health service, were 0.38 (0.35 - 0.40), 0.77 (0.71 - 083), 1.0 (reference group) and 2.06 (1.72 - 2.47) respectively. Conclusion: Increasing resources for mental health services and enabling sufficient continuous mental health services and follow-up may reduce the risk of injury among populations with mental health conditions.

The Acquisition and Utility of the Family Medical History in Primary Care: A Cross-Sectional Study

Background: Acquisition of family medical history (FMH) is emphasized as a part of obtaining a complete medical history, but whether FMH is consistently documented and utilized in primary care, as well as how it can affect patient care in this context, remains unclear. Thus, the objectives of this study were to determine: 1) if FMH is regularly acquired in a representative primary care practice (the Queen’s Family Health Team, QFHT);2) what is included in the FMH obtained;3) what the utility of FMH is with regards to patient management in primary care;and 4) to utilize healthcare practitioners’ perspectives in order to elucidate any findings regarding the acquisition and utility of FMH at the QFHT. Methods: Patients were interviewed in order to obtain their FMH. For each patient, the FMH obtained was compared to the FMH documented in the patient’s record to determine the record’s completeness. Each patient’s FMH was analyzed for significant history of coronary artery disease (CAD), diabetes mellitus type II (DMII), substance abuse (SA) and colorectal cancer (CRC). Participants were patients scheduled for appointments at the QFHT between May and July 2011. Any patient of the QFHT older than 25 years was eligible to participate. Clinical staff of the QFHT completed an online questionnaire to determine healthcare practitioners’ perspectives regarding the acquisition and utility of FMH. Results: 83 patients participated in the study. Participants ranged in age from 25 - 86 years (median: 63 years);69% were female. FMH present in patients’ records was often either incomplete (42% of charts reviewed) or not documented at all (51% of charts reviewed). Knowledge of FMH can affect patient management in primary care for the diseases assessed (CAD, DMII, SA and CRC). HCP do consider FMH to be important in clinical practice and 86% of respondents stated that they regularly inquired about patients’ FMH. Interpretation: Despite the belief by HCP that FMH is important, there is a disparity between this belief and their practices regarding its documentation and utilization. Finally, analysis of the FMH of the representative population studied shows that information commonly missing in patients’ FMH can affect patient management at a primary care level.

Associations of social participation, demographic, socioeconomic and disease factors with nutritional risk in a group of older Hong Kong adults

Aims: To identify the impact of social participation, socio-demographic, socio-economic and disease factors on nutritional risk among older persons in Hong Kong. Background: Few published work has investigated the relative risks of social participation, demographic, socioeconomic and disease factors with malnutrition in community-living older people, this study is to investigate the associations of these risk factors on the nutritional status in better nutrition support for the old age group. Design: A crosssectional study. Methods: It was a secondary analysis of a database in a mobile community centre between January 2008 and December 2009. One thousand seven hundred and thirty one participants aged between 54 and 103 were collected. With 319 full Mini Nutritional Assessment (MNA) completed, the participants’ demographic, socio-economic data, diseases, and nutritional status were analyzed with relative risk and 95% confidence interval level to identify the factors that make them vulnerable to nutritional risk. Results: The prevalence of malnutrition in the community-dwelling old was 3.95% and 83.7% of the sample was at risk of malnutrition. Living on allowances, young old who was socially engaged and good relationship with family members were at less risk to malnutrition. Conclusions: Special attention should be taken to these groups as they are prone to develop malnutrition.

Attitude toward Safety among Staffs in the Iranian Maternity Care Units of Public Hospitals with High Maternal Death Rate, 2015-2016

Background: Although extensive Mother-friendly Hospital initiatives have been improved the quality of maternity care in Iran, recent national reports have been indicated that obstetrics errors are still common. The current study aimed to assess safety attitude in the maternity care units of public hospitals in a region with high rate of maternal death in Iran. Materials and Methods: Data was collected from 314 midwives, specialist and also managers working in all public hospitals in 2016. The Cronbach’s alpha coefficient was used to analyze psychometric features of the Safety Attitudes Questionnaire (SAQ). Results: 86.2% of the participants (n = 314) completed the questionnaire. Results showed that lower scores in teamwork, safety climate and also job satisfaction subcomponents. The working conditions and stress recognition had the highest negative scores. There was a significant relationship between the following subcomponents and work load: teamwork (r = ﹣0.416, P-value = 0.05), stress recognition (r = 0.40, P-value = 0.05) and also working conditions (r = 0.421;P-value = 0.02). The score of midwives was significantly lower than specialists regarding job satisfaction (P-value = 0.014), working conditions (P-value = 0.02) and also the overall safety attitude score (P-value = 0.001). About 63% of respondents reported no error during the last year. The mean of error reporting during the last year significantly increased among specialists compared to midwives (P-value = 0.001). Conclusion: Maternity care units in the region with high maternal death have been faced with many intangible barriers related to safety attitude such as poor teamwork climate, working condition and also poor stress recognition. It is now needed to promote supportive environment for midwives and also strengthening staff cohesion through guiding the strategic direction of current maternity risk management system in creating open and just culture, improving leadership behaviors among senior managers and also addressing poor staffing levels.

Cardiovascular Risk in Adults and its Association with Health Services Utilization. ENSANUT 2018-2019

Background The use of health services by the adult population is related to cardiovascular risk and its stratification. Cardiovascular risk (CVR) stratification should be a tool for the assessment of the patients and the appropriate control during the process of medical care and utilization of health services for the adults. Objective Evaluate the association between cardiovascular risk (CVR) in adults and the utilization of health services. Material and Methods A secondary analysis was performed of the data from the National Health and Nutrition Survey (ENSANUT) 2018-2019. The CVR classification (risk score) was obtained in 43,070 adults with a previous diagnosis (self-report) and 1,237 adults newly diagnosed. Independent, risk factors and the association between groups of CVR and utilization of preventive, outpatient and hospital services were analyzed. Results More than 85% of adults interviewed have some degree of CVR. Almost half of them have low CVR (48.2%). Older adults with social security predominate in the group with high and very high CVR. Seventy-five percent of adults recently diagnosed have low CVR. In both, there is very little utilization of health services. For adults previously diagnosed CVR, the higher the CVR, the greater the likelihood of utilization of outpatient, preventive and hospital services, in contrast to adults without CVR independent of the marital status, sex, health institution and socioeconomic level. Conclusion The results give evidence of areas of opportunity for improvement in the quality of health services. The evaluation of CVR in primary care and promotion and prevention of CVR should be strengthened.
