RESUMO

BACKGROUND: Nasogastric (NG) feeding tubes are used to deliver nutrition, hydration, and medications to hospitalized infants and children but the ongoing use of non-evidence-based practice (EBP) methods to confirm NG tube (NGT) placement has been associated with adverse patient events. METHODS: A study was undertaken to ascertain if practice changes have occurred since findings from a previous study were published by the New Opportunities for Verification of Enteral tube Location (NOVEL) project. The NOVEL project was an initiative of the American Society of Parenteral and Enteral Nutrition (ASPEN). A survey was distributed to member organizations participating in the NOVEL project. Respondents were also asked if and when a change in practice occurred in the policy for NGT placement verification, if there was variation within the institutional units and if there were barriers to practice change. FINDINGS: Respondents were primarily nurses (205/245) from 166 institutions that provided care to combined adult/pediatric/neonatal (122/166) patients. Respondents indicated a radiograph (64%) or pH measurement (24%) were best practice but in actual practice 42% use pH measurement and 23% use a radiograph to verify NGT placement. There was variability within institutions, with the Neonatal Intensive Care Unit (NICU) most often using aspiration and direct eye visualization to verify placement and the other units within the institutions using EBP method(s). DISCUSSION: Comparing these results to previous work by the NOVEL project shows an increase toward the use of EBP method(s) to verify NGT placement verification. APPLICATION TO PRACTICE: This study demonstrates variation within units at the same facility using methods unsupported by the literature, demonstrating that many centers still rely on non-EBP methods of NG placement confirmation, despite cautions issued by many major healthcare organizations.

RESUMO

We combined viral genome sequencing with contact tracing to investigate introduction and evolution of severe acute respiratory syndrome coronavirus 2 lineages in Santa Clara County, California, from 27 January to 21 March 2020. From 558 persons with coronavirus disease 2019, 101 genomes from 143 available clinical samples comprised 17 lineages, including SCC1 (n = 41), WA1 (n = 9; including the first 2 reported deaths in the United States, with postmortem diagnosis), D614G (n = 4), ancestral Wuhan Hu-1 (n = 21), and 13 others (n = 26). Public health intervention may have curtailed the persistence of lineages that appeared transiently during February and March. By August, only D614G lineages introduced after 21 March were circulating in Santa Clara County.

RESUMO

BACKGROUND: Enteral feeding tubes (EFTs) are commonly used in neonatal practice, but complications from tube misplacement remain a concern. Measuring the pH of EFT aspirate is a recommended method to evaluate EFT placement. A pH value of ≤5.5 is considered predictive of gastric placement. Using this method in infants has been questioned. It is unclear whether infants can produce adequate gastric acid to achieve a pH 5 or less and whether feedings and medications influence pH. PURPOSE: To report EFT aspirate pH values in infants and to evaluate factors potentially influencing pH values. METHODS: A retrospective descriptive study was conducted with 1024 infants with 6979 pH values. Demographic and clinical data were collected including type of EFT, pH of gastric aspirate, feeding method, time of last feeding, and administration of acid suppression medications. The frequency of measured pH values of 5 or less was calculated for each covariate. FINDINGS/RESULTS: The majority (97.51%) of pH values were 5 or less. Orogastric tubes, continuous feeding, a 4-hour or more feeding interval, exposure to medications (proton pump inhibitor, histamine-2 receptor antagonist, or multiple medications) were associated with an increased likelihood of pH values of more than 5. However, with each study variable the majority of pH values were 5 or less. IMPLICATIONS FOR PRACTICE: These findings suggest EFT pH, a recommended method to evaluate the likelihood of gastric placement, can be successfully used in the neonatal population. IMPLICATIONS FOR RESEARCH: Future research should prospectively evaluate EFT pH in infants when compared with clinically indicated radiographs. Other factors that might influence pH should be explored including severity of illness, feeding type, and other medications.

RESUMO

Health care organizations have focused considerable effort and resources on improving patient safety and health care quality. Yet, despite these efforts, patients continue to experience harm events within our institutions. Family engagement is a powerful and often untapped resource to improve the quality and safety of organizations. While the value patients and families bring as partners in improving the safety and quality of health care is implicitly recognized, the adoption of structures to actively involve health care consumers has been slow, particularly in organizational or overall system work. Patients and families can stimulate and drive improved health care services through their involvement at the clinical/point of care, policy/design, and governance levels of the organization. For successful implementation, organization leaders must establish family engagement as a system-level priority. Roles to support the development of a family engagement program, methods to evaluate the level of family engagement, and strategies to enhance and sustain family engagement are described. Although there is limited evidence-based knowledge related to the best practices for family engagement, opportunities exist to drive the family engagement agenda at a regional and national level through participation in networks such as the Centers for Medicare & Medicaid Services Partnership for Patients campaign Hospital Engagement Networks.

RESUMO

OBJECTIVE: The objectives were to develop and validate the Information System Evaluation Tool (ISET), use feedback to modify the institution's clinical information system (CIS), and determine the modifications' success. BACKGROUND: The ability of a CIS to increase patient safety and care quality is dependent on its systems and processes. A survey was needed to provide the specificity necessary to make meaningful system improvements. METHODS: The ISET was pilot tested and revised before being administered before implementation of the CIS. It was administered at 2 times after implementation. The ISET was revised after analysis of the results, and comparisons were made between the times. RESULTS: The ISET is a valid and reliable instrument. Perceptions of the CIS initially decreased, but had significantly improved by 16 months after implementation. CONCLUSIONS: End-users must be convinced that the CIS supports their practice and improves care for adoption to be successful. The ISET measures these perceptions and highlights areas for improvement.

RESUMO

INTRODUCTION: The 2005 Patient Safety and Quality Improvement Act, actualized as a Learning Network (LN), has enabled the Child Health Patient Safety Organization (PSO) to play a vital and novel role in improving the quality and safety of care. This article describes the Child Health PSO and proposes PSOs as a new construct for LNs. METHODS: A PSOs ability to affect patient care depends on member organizations' integration of PSO output into their individual Learning Healthcare Systems. Therefore, the Child Health PSO developed tenets of an LN to improve member engagement in PSO outputs. RESULTS: All Child Health PSO members participate in case-based learning, requiring ongoing and robust participation by all members. The engagement has been strong, with 86% of children's hospitals achieving a case learning activity metric and 60% of children's hospitals submitting cases. From this LNs perspective, 53% of children's hospitals are considered highly engaged. CONCLUSIONS: In the last 10 years, the Child Health PSO has evolved as a viable LN and, to sustain this, has set a target of 100% of participating children's hospitals being highly engaged. The previously inconceivable notion of sharing information to improve patient safety among hospitals is now an expected result of the formation of trusting relationships under a federally certified PSO. According to participants, collaboration is an essential element that empowers individual children's hospitals to eliminate preventable harm.

RESUMO

BACKGROUND AND OBJECTIVES: Serious safety events (SSEs) occur infrequently at individual hospitals, making it difficult to establish trends to improve patient care. Patient safety organizations, such as the Child Health Patient Safety Organization (CHILDPSO), can identify trends and support learning across children's hospitals. We aim to describe longitudinal trends in SSE rates among CHILDPSO member hospitals and describe their sources of harm. METHODS: SSEs from 44 children's hospitals were assigned severity and reported to CHILDPSO from January 1, 2015, to December 31, 2018. SSEs were classified into groups and subgroups based on analysis. Events were then tagged with up to 3 contributing factors. Subgroups with <5 events were excluded. RESULTS: There were 22.5 million adjusted patient days included. The 12-month rolling average SSE rate per 10 000 adjusted patient days decreased from 0.71 to 0.41 (P < .001). There were 830 SSEs reported to CHILDPSO. The median hospital volume of SSEs was 12 events (interquartile range: 6-23), or ∼3 SSEs per year. Of the 830 events, 21.0% were high severity (SSE 1-3) and approximately two-thirds (67.0%, n = 610) were patient care management events, including subgroups of missed, delayed, or wrong diagnosis or treatment; medication errors; and suboptimal care coordination. The most common contributing factor was lack of situational awareness (17.9%, n = 382), which contributed to 1 in 5 (20%) high-severity SSEs. CONCLUSIONS: Hospitals sharing SSE data through CHILDPSO have seen a decrease in SSEs. Patient care management was the most frequently seen. Future work should focus on investigation of contributing factors and risk mitigation strategies.

RESUMO

OBJECTIVES: To develop a computer-based system for modelling and interpreting plasma antiretroviral concentrations for therapeutic drug monitoring (TDM). METHODS: Data were extracted from a prospective TDM study of 199 HIV-infected patients (CCTG 578). Lopinavir (LPV) and efavirenz (EFV) pharmacokinetic (PK) parameters were modelled using a Bayesian method and interpreted by an expert committee of HIV specialists and pharmacologists who made TDM recommendations. These PK models and recommendations formed the knowledge base to develop an artificial intelligence (AI) system that could estimate drug exposure, interpret PK data and generate TDM recommendations. The modelled PK exposures and expert committee TDM recommendations were considered optimum and used to validate results obtained by the AI system. RESULTS: A group of patients, 67 on LPV, 46 on EFV and three on both drugs, were included in this analysis. Correlations were high for LPV and EFV estimated trough and 4 h post-dose concentrations between the Al estimates and modelled values (r > 0.79 for all comparisons; P < 0.0001). Although trough concentrations were similar, significant differences were seen for mean predicted 4 h concentrations for EFV (4.16 microg/ml versus 3.89 microg/ml; P = 0.02) and LPV (7.99 microg/ml versus 8.79 microg/ml; P < 0.001). The AI and expert committee TDM recommendations agreed in 53 out of 69 LPV cases [kappa (kappa) = 0.53; P < 0.001] and 47 out of 49 EFV cases (kappa = 0.91; P < 0.001). CONCLUSION: The AI system successfully estimated LPV and EFV trough concentrations and achieved good agreement with expert committee TDM recommendations for EFV- and LPV-treated patients.

RESUMO

OBJECTIVE: We conducted a randomized, multi-site, controlled trial of a cognitive-behavioral adherence intervention for patients initiating or changing an antiretroviral (ART) regimen. DESIGN: A 3 x 2 factorial design was used with the primary randomization assigning patients (1: 1: 1) to one of two adherence interventions or usual care. METHODS: The five-session adherence interventions consisted of cognitive-behavioral and motivational components, with or without a 2-week pre-treatment placebo practice trial. Intent-to-treat analysis used probability weights and regression tree analysis to account for missing data. RESULTS: A total of 230 patients were randomized; 199 started ART, of whom 74% completed the 48-week study. Electronic monitored adherence outcomes between the two intervention groups did not differ significantly and were thus pooled in analyses. At week 4, 82% of intervention patients had taken at least 90% of their prescribed ART doses, compared with 65% of controls (P < 0.01); this group difference dropped to 12% at week 12 (72 versus 60%; P = 0.15) and 11% at week 24 (66 versus 55%; P = 0.28). Mean adherence in the intervention group was significantly higher than the control group at week 24 (89 versus 81%; P < 0.05) only. There were no group differences with respect to HIV-1 RNA throughout the study. CONCLUSIONS: The effects of the cognitive-behavioral intervention on adherence were modest and transient, and no effects were observed on viral load or CD4 cell count. More robust effects may require a more intense intervention that combines ongoing adherence monitoring and individualized intervention "dosage" that matches the need and performance of each patient.

RESUMO

BACKGROUND: Temporary enteral access devices (EADs), such as nasogastric (NG), orogastric (OG), and postpyloric (PP), are used in pediatric and neonatal patients to administer nutrition, fluids, and medications. While the use of these temporary EADs is common in pediatric care, it is not known how often these devices are used, what inpatient locations have the highest usage, what size tube is used for a given weight or age of patient, and how placement is verified per hospital policy. MATERIALS AND METHODS: This was a multicenter 1-day prevalence study. Participating hospitals counted the number of NG, OG, and PP tubes present in their pediatric and neonatal inpatient population. Additional data collected included age, weight and location of the patient, type of hospital, census for that day, and the method(s) used to verify initial tube placement. RESULTS: Of the 63 participating hospitals, there was an overall prevalence of 1991 temporary EADs in a total pediatric and neonatal inpatient census of 8333 children (24% prevalence). There were 1316 NG (66%), 414 were OG (21%), and 261 PP (17%) EADs. The neonatal intensive care unit (NICU) had the highest prevalence (61%), followed by a medical/surgical unit (21%) and pediatric intensive care unit (18%). Verification of EAD placement was reported to be aspiration from the tube (n = 21), auscultation (n = 18), measurement (n = 8), pH (n = 10), and X-ray (n = 6). CONCLUSION: The use of temporary EADs is common in pediatric care. There is wide variation in how placement of these tubes is verified.

RESUMO

OBJECTIVE: To assess phenotype susceptibility testing (PHENO) with standard of care (SOC) to improve antiretroviral therapy. DESIGN: A prospective, multicenter study of 238 patients taking a stable antiretroviral regimen for > 6 months, with one or two protease inhibitors (PI) and entry HIV RNA > 400 copies/ml. METHOD: Patients were randomized to receive or not receive PHENO results for selecting antiretroviral regimens. Primary outcome was HIV RNA measures. RESULTS: At baseline, median CD4 cell count was 277 x 10 cells/l and HIV RNA was 10 000 copies/ml; 76% had not taken a non-nucleoside reverse transcriptase inhibitor drug (NNRTI). There were significant differences between the groups in selection of baseline nucleoside reverse transcriptase inhibitor (NRTI). At month 6, reduction in HIV RNA was 0.71 and 0.69 log10 copies/ml for PHENO and SOC, respectively; the proportion with < 400 copies/ml (48%) was the same for both groups. No differences were seen at month 12. In a subgroup with resistance to four or more PI, 50% of the PHENO versus 17% of the SOC had HIV RNA < 400 copies/ml at month 6 (P = 0.02). The number of NNRTI and PI, but not NRTI, in the regimen that were active by phenotype at baseline was a strong independent predictor of viral suppression (P < 0.006). Use of alternative NRTI sensitivity cut-offs improved their predictive value. CONCLUSIONS: Although virological outcome was similar in both groups, the potential benefit of PHENO was seen in patients with more resistant virus. Lack of appropriate cut-offs may have partially accounted for the lack of benefit from PHENO and demonstrated the need to identify clinically relevant sensitivity cut-off points.

RESUMO

HIV infection and its treatment can have significant effects on physical appearance and functioning, which can affect self-perceived body image. We assessed the psychometric properties of a newly developed Body Image Scale (BIS), a subjective measure of body image perception in persons with HIV infection, as well as the scale's relationship to disease progression, symptoms, and demographic factors. HIV-positive men (n = 129) and women (n = 21) attending two outpatient HIV clinics were administered the BIS survey along with a one-page questionnaire. A subset (n = 38) were administered the survey on two occasions to assess test-retest reliability. Nearly half of the sample (46%) had AIDS and 25% had a CD4 count below 200 cells/mm(3) within the prior 3 months. The BIS had unidimensional factor structure, good internal consistency reliability (Chronbach alpha = 0.91), and good test-retest reliability (r = 0.71, p < 0.001) after controlling for the length of interval between assessments. Patients' current perception of their body image was worse then what they perceived it to be prior to HIV infection (p < 0.001), but better than their perception of how others view people with HIV (p < 0.001). The presence of symptomatic disease (p < 0.001) and a diagnosis of AIDS (p = 0.02) were associated with a less favorable body image, although laboratory markers of disease progression (CD4 count and plasma HIV viral load) were not. We conclude that the BIS has good construct validity and is a highly reproducible measure of self-perceptive of body image in HIV-infected patients. Further exploration of its relationship to psychological well being, medication adherence and other aspects of medical care is indicated.

RESUMO

OBJECTIVES: To examine HIV-positive patients' reports of whether HIV care providers ever talked with them about practicing safer sex and disclosing seropositive status to sex partners. DESIGN: Cross-sectional survey (1998-1999) of HIV-positive men and women sampled randomly at six public HIV clinics in California. METHODS: Participants were interviewed and asked whether applicable clinic providers (physician, physician assistant, nurse practitioner, nurse, social worker, health educator, psychologist, psychiatrist) ever talked with them about safer sex or disclosure. Responses were analyzed by clinic site, HIV medical status (viral load), demographic, and behavioral variables (unprotected intercourse, non-disclosure). RESULTS: The sample (n = 839) included heterosexual men (n = 127), men who have sex with men (MSM; n = 607), and women (n = 105). Thirty-nine percent were white, 36% Hispanic, 17% black, and 8% other/mixed ethnicity. Overall, 71% reported that an applicable provider had talked with them at least once about safer sex (range across clinics, 52-94%); 50% reported discussion of disclosure (range across clinics, 31-78%). Discussion of safer sex was more prevalent with physicians than with other clinic staff. In multivariate analyses, in addition to significant clinic differences, MSM (versus heterosexual men) and whites (versus blacks or Hispanics) were less likely to receive prevention messages on these topics. Patients' behaviors (unsafe sex, non-disclosure) and HIV medical status were not independently associated with provider communication. CONCLUSIONS: HIV clinics differed substantially in the percentage of patients who reported that they received prevention messages from clinic staff. Care providers should assess and overcome barriers to providing prevention messages to patients.

RESUMO

OBJECTIVE: To test the efficacy of brief, safer-sex counseling by medical providers of HIV-positive patients during medical visits. SETTING: Six HIV clinics in California. DESIGN: Clinics were randomized to intervention arms evaluated with cohorts of randomly selected patients measured before and after the intervention. PARTICIPANTS: Five-hundred and eighty-five HIV-positive persons, sexually active prior to enrollment. INTERVENTIONS: Prevention counseling from medical providers supplemented with written information. Two clinics used a gain-framed approach (positive consequences of safer-sex), two used a loss-frame approach (negative consequences of unsafe sex), and two were attention-control clinics (medication adherence). Interventions were given to all patients who attended the clinics. OUTCOME MEASURE: Self-reported unprotected anal or vaginal intercourse (UAV). RESULTS: Among participants who had two or more sex partners at baseline, UAV was reduced 38% (P < 0.001) among those who received the loss-frame intervention. UAV at follow-up was significantly lower in the loss-frame arm [odds ratio (OR), 0.42; 95% confidence interval (CI), 0.19-0.91; P = 0.03] compared with the control arm. Using generalized estimating equations (GEE) to adjust for clustering did not change the conclusions (OR, 0.34; 95% CI, 0.24-0.49; P = 0.0001). Similar results were obtained in participants with casual partners at baseline. No effects were seen in participants with only one partner or only a main partner at baseline. No significant changes were seen in the gain-frame arm. CONCLUSIONS: Brief provider counseling emphasizing the negative consequences of unsafe sex can reduce HIV transmission behaviors in HIV-positive patients presenting with risky behavioral profiles.

RESUMO

OBJECTIVE: To evaluate the clinical significance of hypersusceptibility to non-nucleoside reverse transcriptase inhibitors (NNRTI). DESIGN: Analysis of a prospective clinical trial cohort. PATIENTS: NNRTI-naive patients failing a stable antiretroviral regimen. MEASUREMENTS: HIV phenotype, HIV RNA, and CD4 cell counts were prospectively collected after patients changed to a new regimen. Hypersusceptibility to NNRTI was defined as a fold-change (FC) in IC50 (inhibitory concentration of 50%) of < 0.4. RESULTS: The 177 patients had a mean HIV RNA of 4.1 log10 copies/ml, CD4 cell count of 322 x 10(6) cells/l and 41 months of prior antiretroviral treatment. Hypersusceptibility to one or more NNRTI was present in 29%. Both longer duration and reduced susceptibility to nucleoside reverse transcriptase inhibitors were associated with efavirenz hypersusceptibility (P < 0.05). NNRTI-containing regimens were initiated in 106 patients at baseline. The mean change in log HIV RNA after 6 months was greater for patients with hypersusceptibility (-1.2 log10 copies/ml; n = 21) than in patients without (-0.8 log10 copies/ml; n = 77) (P = 0.016). Differences persisted to month 12 (P = 0.023). Multiple linear regression models confirmed that hypersusceptibility to NNRTI was a significant independent predictor of the magnitude of early (months 1-4) HIV RNA reduction, after accounting for the baseline HIV RNA and the number of drugs to which the patient's virus was susceptible (P < 0.02). CD4 cell increases (months 4-10) were 28- 60 x 10(6) cells/l greater in patients with hypersusceptible virus (P < or = 0.1). CONCLUSION: NNRTI hypersusceptibility occurred in more than 20% of nucleoside-experienced patients and was associated with greater reduction of HIV RNA and increase in CD4 cells.

RESUMO

BACKGROUND: Although adherence clearly influences response to antiretroviral therapy (ART), accurate assessment of adherence is problematic. The objective of this analysis was to assess the independent predictive value of protease inhibitor (PI) concentrations as a supplement to self-report as markers of medication adherence. METHODS: This retrospective analysis was conducted from a prospective clinical trial designed to compare the outcomes of frequent versus infrequent HIV RNA measurement used to manage antiretroviral therapy. For 131 patients, self-reported medication adherence, HIV RNA levels, CD4 counts and PI concentrations (unannounced, random samples) were measured at baseline (when patients changed to a new regimen) and every 2 months thereafter. The change in HIV RNA from baseline to month 6 (area-based measure) was used to evaluate overall response. The proportion of measured PI concentrations below the detection limit was used as an alternative marker of adherence. An undetectable concentration would be expected after missing a single dose. RESULTS: The mean baseline CD4 count was 125 cells/mm3 and the mean HIV RNA level was 4.7 log10 copies/ml. The mean change in log10 HIV RNA was -0.73 copies/ml. The mean percentage of self-reported adherence was 91% (range: 15-100%) and the mean proportion of undetectable PI concentrations was 27% (range: 0-100%, mean 2.5 samples/patient). The correlation between the two measures was -0.23 (P=0.009). In a multivariate model, percentage of visits with undetectable PI concentrations (P=0.02), percentage of medication adherence (P=0.02), baseline HIV RNA level (P=0.005), prior PI use (P=0.0004), prior lamivudine (3TC) use (P=0.0009) and randomization to the frequent HIV RNA measurement group (P<0.0001) were all related to change in HIV RNA. After accounting for adherence, patients who always had detectable PI concentrations had an average of 0.4 log10 additional HIV RNA reduction compared with those who had no detectable concentrations. CONCLUSIONS: Repeated, random PI concentration values are independently predictive of virological response and may add to self-report of adherence in understanding the response to ART.

RESUMO

Safety concerns regarding the verification of nasogastric feeding tube placement prompted the American Society for Parenteral and Enteral Nutrition to call for an interdisciplinary, interorganizational group to work on best practices and new technologies to address this issue in pediatric patients. This commentary calls for the development of specialized teams within hospitals to improve the quality of care provided to children and infants who require nasogastric feeding tubes. It is expands on the information presented in an article in the issue by Irving et al regarding the current status of nasogastric tube placement and verification methods.

RESUMO

Placement of a nasogastric enteral access device (NG-EAD), often referred to as a nasogastric tube, is common practice and largely in the domain of nursing care. Most often an NG-EAD is placed at the bedside without radiographic assistance. Correct initial placement and ongoing location verification are the primary challenges surrounding NG-EAD use and have implications for patient safety. Although considered an innocuous procedure, placement of an NG-EAD carries risk of serious and potentially lethal complications. Despite acknowledgment that an abdominal radiograph is the gold standard, other methods of verifying placement location are widely used and have success rates from 80% to 85%. The long-standing challenges surrounding bedside placement of NG-EADs and a practice alert issued by the Child Health Patient Safety Organization on this issue were the stimuli for the conception of The New Opportunities for Verification of Enteral Tube Location Project sponsored by the American Society for Parenteral and Enteral Nutrition. Its mission is to identify and promote best practices with the potential of technology development that will enable accurate determination of NG-EAD placement for both the inpatient and outpatient pediatric populations. This article presents the challenges of bedside NG-EAD placement and ongoing location verification in children through an overview of the current state of the science. It is important for all health care professionals to be knowledgeable about the current literature, to be vigilant for possible complications, and to avoid complacency with NG-EAD placement and ongoing verification of tube location.
