Resultados de un programa de rehabilitación domiciliaria tras hospitalización en pacientes con fractura de cadera

IntroductionHip fracture is one of the most frequent disabling injuries, presenting serious complications during the acute and subacute phase. Rehabilitation at home, after hospital discharge, allows rapid functional recovery. The objective of this study is to evaluate the possible usefulness of a home rehabilitation program in patients with hip fracture integrated in a Hospital at Home Unit.MethodsRetrospective study that consecutively included patients accepted for home rehabilitation treatment between September 9, 2019 and December 31, 2021 in the Hospital at Home Unit of the Hospital Universitario de la Ribera, Alzira, Valencia. Demographic, clinical, functional and quality of care variables were collected.ResultsTwo hundred twenty-four subjects were included. The mean age was 84.6 (SD 7.7) years, with 66% women and 34% men, with 32% of patients diagnosed with dementia in one of its degrees of severity. The mean hospital stay was 8.4 (SD 4.1) days and 6.5 (5.3) days in the Hospital at Home Unit rehabilitation program. 90% of the patients included in the program reached the therapeutic goal outlined during hospital admission.ConclusionsThe home rehabilitation of patients with hip fracture contributes to a functional recovery of the patient in a shorter time. Further studies are necessary to confirm the results obtained.     

A new multidisciplinary home care telemedicine system to monitor stable chronic human immunodeficiency virus-infected patients: a randomized study

Background

Antiretroviral therapy has changed the natural history of human immunodeficiency virus (HIV) infection in developed countries, where it has become a chronic disease. This clinical scenario requires a new approach to simplify follow-up appointments and facilitate access to healthcare professionals.

Methodology

We developed a new internet-based home care model covering the entire management of chronic HIV-infected patients. This was called Virtual Hospital. We report the results of a prospective randomised study performed over two years, comparing standard care received by HIV-infected patients with Virtual Hospital care. HIV-infected patients with access to a computer and broadband were randomised to be monitored either through Virtual Hospital (Arm I) or through standard care at the day hospital (Arm II). After one year of follow up, patients switched their care to the other arm. Virtual Hospital offered four main services: Virtual Consultations, Telepharmacy, Virtual Library and Virtual Community. A technical and clinical evaluation of Virtual Hospital was carried out.

Findings

Of the 83 randomised patients, 42 were monitored during the first year through Virtual Hospital (Arm I) and 41 through standard care (Arm II). Baseline characteristics of patients were similar in the two arms. The level of technical satisfaction with the virtual system was high: 85% of patients considered that Virtual Hospital improved their access to clinical data and they felt comfortable with the videoconference system. Neither clinical parameters [level of CD4+ T lymphocytes, proportion of patients with an undetectable level of viral load (p = 0.21) and compliance levels >90% (p = 0.58)] nor the evaluation of quality of life or psychological questionnaires changed significantly between the two types of care.

Conclusions

Virtual Hospital is a feasible and safe tool for the multidisciplinary home care of chronic HIV patients. Telemedicine should be considered as an appropriate support service for the management of chronic HIV infection.

Hospital at home for patients with acute exacerbations of chronic obstructive pulmonary disease: systematic review of evidence

Objectives To evaluate the efficacy of hospital at home schemes compared with inpatient care in patients with acute exacerbations of chronic obstructive pulmonary disease (COPD).Design A systematic review of randomised controlled trials.Main outcome measure Mortality and readmission to hospital.Results Seven trials with 754 patients were included in the review. Hospital readmission and mortality were not significantly different when hospital at home schemes were compared with inpatient care (relative risk 0.89, 95% confidence interval 0.72 to 1.12, and 0.61, 0.36 to 1.05, respectively). However, compared with inpatient care, hospital at home schemes were associated with substantial cost savings as well as freeing up hospital inpatient beds.Conclusions Hospital at home schemes can be safely used to care for patients with acute exacerbations of COPD who would otherwise be admitted to hospital. Clinicians should consider this form of management, especially as there is increasing pressure for inpatient beds in the United Kingdom.     

Effect of correcting outcome data for case mix: an example from stroke medicine.

OBJECTIVE--To show the influence of variations in case mix on clinical outcome indicators for patients admitted to hospital with acute stroke. DESIGN--"Before and after" cohort study, with prospective, consecutive identification of patients and prospective follow up; multiple logistic regression analyses to correct for case mix variations. SETTING--University teaching hospital. SUBJECTS--216 patients with stroke identified before the introduction of an organised stroke service, and 252 patients with stroke identified after its introduction. MAIN OUTCOME MEASURES--Case fatality at 30 days and 12 months; for survivors at 12 months, proportions of patients who were independent (according to the Oxford handicap scale) and of those living at home. RESULTS--Crude outcome data suggested that patients in the cohort identified after the introduction of the stroke service were significantly more likely to be alive, independent, and living at home than patients managed before the stroke service. After adjustment for age and sex these "improvements" were less impressive but still significant. After adjustment for many other possible prognostic indicators, however, the differences between the two groups for all four outcomes were non-significant, suggesting that the "improvements" may have been entirely due to differences in case mix between the two cohorts, rather than the new stroke service. CONCLUSIONS--Variations in case mix have a crucial influence on the interpretation of outcome data, and this is particularly important in non-randomised comparative studies. Such studies, comparing performance within and between different provider units, are likely to become increasingly common in the new reformed NHS. To allow meaningful interpretation, these studies must try to correct for case mix.     

Nonagenarios en los servicios de Medicina Interna españoles

Objetive

To describe the demographic and clinical profile of nonagenarian patients admitted to Internal Medicine departments in Spanish hospitals, and to compare it with younger patients.

Methods

We identified, through the MBDS (Basic Minimum Data Set), every patient older than 90 years admitted to Internal Medicine Departments of the Spanish National Health Service public hospitals between 2005- 2008. Hospital discharge data were obtained from the MBDS. A diagnosis-related group (DRG) was identified for every patient. The DRG 21.0 version was used. We compared this nonagenarian group with data of younger adult people. All centres submit this information to the Spanish Health Ministry. The Charlson Index (CCI) was used to determine comorbidity. All statistical analyses were performed using SPSS 14.0.

Results

The sample included 131,434 patients over 90 years (6% of total patients admitted), with 2,222 patients being over 100 years. There were 45.3% female patients under 90 years, compared to 67.3% over 90 years (P<.001). The top ten DRGs listed in the older group included three new conditions not present in the younger one: pulmonary oedema (DRG: 87), severe urinary tract infection (DRG: 320), and severe respiratory tract infection (DRG: 540). The first 5 DRG were: pneumonia/bronchitis (541): 11.9%, heart failure (127): 8.9%, rhythm disorders (544): 7.5%, pulmonary oedema (87): 3.8%, and other respiratory diseases (89): 3.24%. In any case the incidence of these conditions was higher than those found in younger patients. Among this top ten, only COPD and angina had a higher rate in the younger group. The incidence of hospital deaths were 9.1% among the younger group, and 21.8% among the nonagenarians (P<.001). If only the first 48 hours after admission are taken into account, the rates were 2.2% vs 6% (P<.001). The majority (78.2%) of nonagenarian patients return home after discharge

Conclusions

1) There are a high number of nonagenarians patients admitted in hospital Internal Medicine Departments; 2) The number of women increases with age; 3) List of diagnosis varies according with age; 4) Hospital death rates increase with age, both in first two days and total stay, and 5) The majority of these patients are able to return home after discharge.     

Care of the terminally ill at home.

Care of the terminally ill at home demands the attention of the medical and paramedical community. Patients who choose to remain at home while death approaches must be given full physical, emotional and psychological support by the attending physician and home care services personnel. In 1974 the Vancouver early hospital discharge home care service provided such care to 47 patients. Generally both patient and family were happy with the program. A few families were unable to cope for more than a few days but most continued the care almost to the end, a large number (14) keeping the patient at home until death occurred. Added benefits are the lower costs and the freeing of hospital beds.     

Earthworms near leprosy patients' homes are negative for acid-fast bacilli by fite stain,providing no link between leprous armadillos (Dasypus novemcinctus) and human leprosy

Enzootic leprosy has been recognized in armadillos in Louisiana since 1975. Contact with armadillos is being assessed as a risk factor for leprosy in three white women, lifelong residents of separate rural areas in northern Louisiana, which is a region without endemic leprosy. None has had any known exposure to human leprosy. Each was aware of armadillos (Dasypus novemcinctus) near or under her home for decades. In considering Possible environmental sources forMycobacterium leprae, we observed that all three had earthworm growth areas for fishing bait where soil was kept moist near their homes. The worms attracted armadillos. Since armadillos subsist on worms, grubs, and insects and because of the common feature of a worm farm near each home, we reasoned that earthworms might containM. leprae and be part of a cycle involving the armadillo and human beings. Worms from each home worm farm were studied. One site was sampled twice at patient 1's home, five sites were sampled once at patient 2's home, and three sites were sampled once at patient 3's home. A sample consisted of 3–4 worms, which were washed, purged, fixed live in 10% formalin, embedded in paraffin, sectioned, and stained with the Fite stain. Each was sagittally sectioned and examined by three independent observers. No acid-fast bacilli or other acid-fast structures were identified. We conclude that it is unlikely that earthworms are an environmental source or reservoir ofM. leprae.     

Village-Randomized Clinical Trial of Home Distribution of Zinc for Treatment of Childhood Diarrhea in Rural Western Kenya

Background

Zinc treatment shortens diarrhea episodes and can prevent future episodes. In rural Africa, most children with diarrhea are not brought to health facilities. In a village-randomized trial in rural Kenya, we assessed if zinc treatment might have a community-level preventive effect on diarrhea incidence if available at home versus only at health facilities.

Methods

We randomized 16 Kenyan villages (1,903 eligible children) to receive a 10-day course of zinc and two oral rehydration solution (ORS) sachets every two months at home and 17 villages (2,241 eligible children) to receive ORS at home, but zinc at the health–facility only. Children’s caretakers were educated in zinc/ORS use by village workers, both unblinded to intervention arm. We evaluated whether incidence of diarrhea and acute lower respiratory illness (ALRI) reported at biweekly home visits and presenting to clinic were lower in zinc villages, using poisson regression adjusting for baseline disease rates, distance to clinic, and children’s age.

Results

There were no differences between village groups in diarrhea incidence either reported at the home or presenting to clinic. In zinc villages (1,440 children analyzed), 61.2% of diarrheal episodes were treated with zinc, compared to 5.4% in comparison villages (1,584 children analyzed, p<0.0001). There were no differences in ORS use between zinc (59.6%) and comparison villages (58.8%). Among children with fever or cough without diarrhea, zinc use was low (<0.5%). There was a lower incidence of reported ALRI in zinc villages (adjusted RR 0.68, 95% CI 0.46–0.99), but not presenting at clinic.

Conclusions

In this study, home zinc use to treat diarrhea did not decrease disease rates in the community. However, with proper training, availability of zinc at home could lead to more episodes of pediatric diarrhea being treated with zinc in parts of rural Africa where healthcare utilization is low.

The Zanzibar clove industry

For about 150 years cloves have been a major export crop of Zanzibar. The industry was established through large plantations run with slave labor but these have been progressively fragmented into smaller holdings. Throughout this century the industry at home has faced several recurring problems, the worst of which are tree diseases, ageing tree populations and occasional neglect of trees. As a result, replanting has been crucial to the maintenance of the industry which has also been strengthened by government assistance. Overseas, Zanzibar faced little competition in the world clove market until recently and this is now being aggravated by increasing self-sufficiency in Indonesia. The future of the Zanzibar industry will depend on its ability to cope with the problems of the industry at home and on its success at selling cloves in an increasingly competitive world market.     

A procedure for evaluation of the indoor environment

Exposure to substances found in the indoor environment is known totrigger respiratory illnesses such as asthma. Despite this knowledge,information on how to identify and remove these exposures is scarce. Toaddress this issue, we describe a program of environmental assessmentdeveloped at Children's Mercy Hospital in Kansas City, Missouri. Weevaluated buildings using a standardized assessment protocol. Thisprotocol included a combination of background information, visualinspection, volumetric air sampling, bulk sampling of suspicious areas,antigen measurement of housedust, and general measurements of the indoorclimate. We inspected a total of 63 buildings including 49 single unitstructures, 4 apartments, 4 town homes, 3 schools, 2 office buildings,and 1 mobile home. Most of these locations were identified because ofrespiratory ailments reported by the occupants. A screeningquestionnaire revealed factors that are known to be associated withfungal contamination such as leaks or flooding in 78% of thebuildings. Visual inspection confirmed these sources of contamination inthe majority of structures. Volumetric air sampling identified a highproportion of buildings with airborneAspergillus/Penicillium species. Stachybotrys wasfound in nearly 30% of these structures both in air and onsurface samples, and surprisingly, Stachybotrys spores werefound only in air in nearly 20%. Climactic factors were onlyweakly associated with fungal contamination. The homes of patients withrespiratory diseases often have significant fungal contamination thatcan be identified with a questionnaire. Using this standardizedapproach, factors associated with respiratory illnesses, usually fungalcontamination, frequently can be identified. Whether removal of theoffending exposure will lead to improve health remains to bedetermined.     

Does hospital at home for palliative care facilitate death at home? Randomised controlled trial

ObjectiveTo evaluate the impact on place of death of a hospital at home service for palliative care.DesignPragmatic randomised controlled trial.SettingFormer Cambridge health district.Participants229 patients referred to the hospital at home service; 43 randomised to control group (standard care), 186 randomised to hospital at home.InterventionHospital at home versus standard care.ResultsTwenty five (58%) control patients died at home compared with 124 (67%) patients allocated to hospital at home. This difference was not significant; intention to treat analysis did not show that hospital at home increased the number of deaths at home. Seventy three patients randomised to hospital at home were not admitted to the service. Patients admitted to hospital at home were significantly more likely to die at home (88/113; 78%) than control patients. It is not possible to determine whether this was due to hospital at home itself or other characteristics of the patients admitted to the service. The study attained less statistical power than initially planned.ConclusionIn a locality with good provision of standard community care we could not show that hospital at home allowed more patients to die at home, although neither does the study refute this. Problems relating to recruitment, attrition, and the vulnerability of the patient group make randomised controlled trials in palliative care difficult. While these difficulties have to be recognised they are not insurmountable with the appropriate resourcing and setting.

Key messages

• Terminally ill patients allocated to hospital at home were no more likely to die at home than patients receiving standard care
• Although the subsample of patients actually admitted to hospital at home did show a significant increase in likelihood of dying at home, whether this was due to the service itself or the characteristics of patients admitted to hospital at home could not be determined
• The need to balance ideal research design against the realities of evaluation of palliative care had the effect that the trial achieved less statistical power than originally planned
• Particular problems were that many patients failed to receive the allocated intervention because of the unpredictable nature of terminal illness, inclusion of other service input alongside hospital at home, and the wide range of standard care available
• The trial illustrated problems associated with randomised controlled trials in palliative care, none of which are insurmountable but which require careful consideration and resourcing before future trials are planned

     

Do-not-resuscitate order. What happens after hospital discharge?

We observed 55 inpatients with "do-not-resuscitate" (DNR) orders to determine what happened to their DNR status after hospital discharge. All were admitted to the medical service of a Department of Veterans Affairs hospital. Of the 55 patients, 16 died in the hospital, 10 were discharged to inpatient hospice units, and 1 was transferred to an acute care hospital. An additional 19 patients were discharged to nursing homes. The other 9 patients (16% of the total) survived their hospital stays; 6 successful contacts were made with patients'' spouses. In 1 case the spouse thought a DNR order was no longer desirable. In the other 5 cases the spouse said the DNR status was "probably" or "definitely" still warranted, but only 1 spouse had a written DNR order at home. We contacted 9 of the 14 house officers who had cared for the patients in hospital. Only 2 had ever written a DNR order after hospital discharge. Two house officers said they routinely discussed with family members a patient''s expected dying process at home. Unwanted resuscitation is as undesirable at home as in the hospital. Physicians should discuss future resuscitation procedures with patients who have DNR orders at the time of hospital discharge. Physicians, paramedic service directors, and policymakers also should develop protocols and standardized home DNR orders so that paramedics can honor the wishes of patients in the prehospital setting.     

Incidence and Risk Factors for Neonatal Tetanus in Admissions to Kilifi County Hospital,Kenya

Background

Neonatal Tetanus (NT) is a preventable cause of mortality and neurological sequelae that occurs at higher incidence in resource-poor countries, presumably because of low maternal immunisation rates and unhygienic cord care practices. We aimed to determine changes in the incidence of NT, characterize and investigate the associated risk factors and mortality in a prospective cohort study including all admissions over a 15-year period at a County hospital on the Kenyan coast, a region with relatively high historical NT rates within Kenya.

Methods

We assessed all neonatal admissions to Kilifi County Hospital in Kenya (1999–2013) and identified cases of NT (standard clinical case definition) admitted during this time. Poisson regression was used to examine change in incidence of NT using accurate denominator data from an area of active demographic surveillance. Logistic regression was used to investigate the risk factors for NT and factors associated with mortality in NT amongst neonatal admissions. A subset of sera from mothers (n = 61) and neonates (n = 47) were tested for anti-tetanus antibodies.

Results

There were 191 NT admissions, of whom 187 (98%) were home deliveries. Incidence of NT declined significantly (Incidence Rate Ratio: 0.85 (95% Confidence interval 0.81–0.89), P<0.001) but the case fatality (62%) did not change over the study period (P = 0.536). Younger infant age at admission (P = 0.001) was the only independent predictor of mortality. Compared to neonatal hospital admittee controls, the proportion of home births was higher among the cases. Sera tested for antitetanus antibodies showed most mothers (50/61, 82%) had undetectable levels of antitetanus antibodies, and most (8/9, 89%) mothers with detectable antibodies had a neonate without protective levels.

Conclusions

Incidence of NT in Kilifi County has significantly reduced, with reductions following immunisation campaigns. Our results suggest immunisation efforts are effective if sustained and efforts should continue to expand coverage.     

Prospective study of the disadvantage of people from ethnic minority groups applying to medical schools in the United Kingdom.

To assess whether the ethnic origin of applicants affects their likelihood of being accepted into medical school in the United Kingdom the outcome for the 2399 applicants who applied to read medicine at university in 1986 and included St Mary''s Hospital Medical School as one of their five choices was studied prospectively. Altogether 2040 of the 2399 applicants were British (United Kingdom) nationals, constituting 24.7% (n = 8249) of all home applicants for medicine in 1986, and 1971 of them with postal addresses in the United Kingdom were sent questionnaires asking about their ethnic origin, whether English was their first language, and about their attitudes to ethnic monitoring. A total of 1817 (92.2%) applicants returned the questionnaire, 401 (22.6%) saying that they were from an ethnic minority group and 393 (21.6%) having non-European surnames. Multiple logistic regression identified 11 significant predictors of successful application, of which grades at O and A level, application after A levels, and date of application were the most important. After taking these four variables into account the predicted acceptance rates for home students on the basis of their application forms alone were 47.8% for white applicants and 35.6% for applicants from ethnic minority groups compared with actual acceptance rates of 49.6% and 27.3%, respectively. The difference in success of white and non-white applicants could partly but not entirely be explained by differences in the characteristics considered to be important in a professional context by selectors during shortlisting of candidates: academic ability, interests, and contribution to the community. No differences in the success rate of applicants from ethnic minority groups to individual medical schools could be identified. More research is needed to discover how perceptions of professional suitability are assessed from application forms and interviews.     

Ebola Outbreak Response; Experience and Development of Screening Tools for Viral Haemorrhagic Fever (VHF) in a HIV Center of Excellence Near to VHF Epicentres

Introduction

There have been 3 outbreaks of viral hemorrhagic fever (VHF) in Uganda in the last 2 years. VHF often starts with non-specific symptoms prior to the onset of haemorrhagic signs. HIV clinics in VHF outbreak countries such as Uganda see large numbers of patients with HIV 1/2 infection presenting with non-specific symptoms every day. Whilst there are good screening tools for general health care facilities expecting VHF suspects, we were unable to find tools for use in HIV or other non-acute clinics.

Methods

We designed tools to help with communication to staff, infection control and screening of HIV patients with non-specific symptoms in a large HIV clinic during the outbreaks in Uganda. We describe our experiences in using these tools in 2 Ebola Virus Disease outbreaks in Uganda.

Results

During the Ebola Virus Disease (EVD) outbreaks, enhanced infection control and communication procedures were implemented within 24 hours of the WHO/Ministry of Health announcement of the outbreaks. During course of these outbreaks the clinic saw 12,544 patients with HIV 1/2 infection, of whom 3,713 attended without an appointment, suggesting new symptoms. Of these 4 were considered at risk of EVD and seen with full infection procedures; 3 were sent home after further investigation. One patient was referred to the National Referral Hospital VHF unit, but discharged on the same day. One additional VHF suspect was identified outside of a VHF outbreak; he was transferred to the National Referral Hospital and placed in isolation within 2 hours of arriving at the HIV clinic.

Discussion

Use of simple screening tools can be helpful in managing large numbers of symptomatic patients attending for routine and non-routine medical care (including HIV care) within a country experiencing a VHF outbreak, and can raise medical staff awareness of VHF outside of the epidemics.     

Mechanical Thrombectomy for Ischaemic Stroke: The First UK Case Series

Background and Purpose

Endovascular treatments have the potential to accelerate reperfusion in acute ischaemic stroke with large vessel occlusion. In the UK only a few stroke centres offer this interventional option. The University Hospital of North Staffordshire (UHNS) has treated the largest number of cases in the UK. Results of the first 106 endovascular treatments (EVT) are presented here.

Methods

All patients treated with EVT (intra-arterial thrombolysis (IAT), mechanical thrombectomy (MT) or both, or an attempt at intervention) for acute stroke at UHNS, Stoke-on-Trent, UK, were entered into a prospective register. Baseline demographic and clinical data, the National Institutes for Health Stroke Scale (NIHSS), imaging results including Thrombolysis in Cerebral Infarction (TICI) score, and complications were recorded. Mortality, and modified Rankin score (mRS) were assessed at 90 days.

Results

From December 2009 to January 2013 106 patients (mean age 64 years, median baseline NIHSS 18) were treated with EVT (thrombectomy ± IAT 83%, IAT alone 13%, neither 4%). Seventy-eight per cent of occlusions were in the anterior circulation. Intravenous bridging thrombolysis was performed in 81%. Revascularization was successful (TICI 2b/3) in 84%. The median time from stroke onset to the end of the procedure was 6 h 03 min. A good outcome (mRS≤2) at 90 days was achieved in 48% with a mortality of 15%. Fatal or nonfatal symptomatic intracranial haemorrhage (sICH) within 10 days occurred in 9%. The median length of stay was 14 days (31% discharged home ≤7 days).

Conclusions

EVT led to good clinical outcomes in almost 50% of patients with severe strokes.     

Identification of Nocardia species using matrix-assisted laser desorption/ionization–time-of-flight mass spectrometry

Background

The MALDI (matrix-assisted laser desorption/ionization) Biotyper system for bacterial identification has already been utilized in clinical microbiology laboratories as a successful clinical application of protoemics. However, in cases of Nocardia, mass spectra suitable for MALDI Biotyper identification are often not obtained if such specimens are processed like general bacteria. This problem is related to the insufficiencies in bacterial spectrum databases that preclude accurate specimen identification. Here, we developed a bacterial processing method to improve mass spectra from specimens of the genus Nocardia. In addition, with the new processing method, we constructed a novel in-house bacterial database that combines a commercial database and mass spectra of Nocardia strains from the Department of Clinical Laboratory at Chiba University Hospital (DCLC) and the Medical Mycology Research Center at Chiba University (MMRC).

Results

The newly developed method (Nocardia Extraction Method at DCLC [NECLC]) based on ethanol-formic acid extraction (EFAE) improved mass spectra obtained from Nocardia specimens. The Nocardia in-house database at Chiba University Hospital (NDCUH) was then successfully validated. In brief, prior to introduction of the NECLC and NDCUH, 10 of 64 (15.6%) clinical isolates were identified at the species level and 16 isolates (25.0%) could only be identified at the genus level. In contrast, after the introduction, 58 isolates (90.6%) were identified at the species level and 6 isolates (9.4%) were identified at the genus level.

Conclusions

The results of this study suggest that MALDI-TOF (time-of-flight) Biotyper system can identify Nocardia accurately in a short time in combination with a simple processing method and an in-house database.

Self-Administered Outpatient Antimicrobial Infusion by Uninsured Patients Discharged from a Safety-Net Hospital: A Propensity-Score-Balanced Retrospective Cohort Study

Background

Outpatient parenteral antimicrobial therapy (OPAT) is accepted as safe and effective for medically stable patients to complete intravenous (IV) antibiotics in an outpatient setting. Since, however, uninsured patients in the United States generally cannot afford OPAT, safety-net hospitals are often burdened with long hospitalizations purely to infuse antibiotics, occupying beds that could be used for patients requiring more intensive services. OPAT is generally delivered in one of four settings: infusion centers, nursing homes, at home with skilled nursing assistance, or at home with self-administered therapy. The first three—termed healthcare-administered OPAT (H-OPAT)—are most commonly used in the United States by patients with insurance funding. The fourth—self-administered OPAT (S-OPAT)—is relatively uncommon, with the few published studies having been conducted in the United Kingdom. With multidisciplinary planning, we established an S-OPAT clinic in 2009 to shift care of selected uninsured patients safely to self-administration of their IV antibiotics at home. We undertook this study to determine whether the low-income mostly non-English-speaking patients in our S-OPAT program could administer their own IV antimicrobials at home with outcomes as good as, or better than, those receiving H-OPAT.

Methods and Findings

Parkland Hospital is a safety-net hospital serving Dallas County, Texas. From 1 January 2009 to 14 October 2013, all uninsured patients meeting criteria were enrolled in S-OPAT, while insured patients were discharged to H-OPAT settings. The S-OPAT patients were trained through multilingual instruction to self-administer IV antimicrobials by gravity, tested for competency before discharge, and thereafter followed at designated intervals in the S-OPAT outpatient clinic for IV access care, laboratory monitoring, and physician follow-up. The primary outcome was 30-d all-cause readmission, and the secondary outcome was 1-y all-cause mortality. The study was adequately powered for readmission but not for mortality. Clinical, sociodemographic, and outcome data were collected from the Parkland Hospital electronic medical records and the US census, constituting a historical prospective cohort study. We used multivariable logistic regression to develop a propensity score predicting S-OPAT versus H-OPAT group membership from covariates. We then estimated the effect of S-OPAT versus H-OPAT on the two outcomes using multivariable proportional hazards regression, controlling for selection bias and confounding with the propensity score and covariates.Of the 1,168 patients discharged to receive OPAT, 944 (81%) were managed in the S-OPAT program and 224 (19%) by H-OPAT services. In multivariable proportional hazards regression models controlling for confounding and selection bias, the 30-d readmission rate was 47% lower in the S-OPAT group (adjusted hazard ratio [aHR], 0.53; 95% CI 0.35–0.81; p = 0.003), and the 1-y mortality rate did not differ significantly between the groups (aHR, 0.86; 95% CI 0.37–2.00; p = 0.73). The S-OPAT program shifted a median 26 d of inpatient infusion per patient to the outpatient setting, avoiding 27,666 inpatient days. The main limitation of this observational study—the potential bias from the difference in healthcare funding status of the groups—was addressed by propensity score modeling.

Conclusions

S-OPAT was associated with similar or better clinical outcomes than H-OPAT. S-OPAT may be an acceptable model of treatment for uninsured, medically stable patients to complete extended courses of IV antimicrobials at home.     

Outcomes of Renal Transplantation in HIV-1 Associated Nephropathy

Introduction

Several studies have demonstrated that renal transplantation in HIV positive patients is both safe and effective. However, none of these studies have specifically examined outcomes in patients with HIV-associated nephropathy (HIVAN).

Methods

Medical records of all HIV-infected patients who underwent kidney transplantation at Johns Hopkins Hospital between September 2006 and January 2014 were reviewed. Data was collected to examine baseline characteristics and outcomes of transplant recipients with HIVAN defined pathologically as collapsing focal segmental glomerulosclerosis (FSGS) with tubulo-interstitial disease.

Results and Discussion

During the study period, a total of 16 patients with HIV infection underwent renal transplantation. Of those, 11 patients were identified to have biopsy-proven HIVAN as the primary cause of their end stage renal disease (ESRD) and were included in this study. They were predominantly African American males with a mean age of 47.6 years. Seven (64%) patients developed delayed graft function (DGF), and 6 (54%) patients required post-operative dialysis within one week of transplant. Graft survival rates at 1 and 3 years were 100% and 81%, respectively. Acute rejection rates at 1 and 3 years were 18% and 27%, respectively. During a mean follow up of 3.4 years, one patient died.

Conclusions

Acute rejection rates in HIVAN patients in this study are higher than reported in the general ESRD population, which is similar to findings from prior studies of patients with HIV infection and ESRD of various causes. The high rejection rates appear to have no impact on short or intermediate term graft survival.     

Reaching Mothers and Babies with Early Postnatal Home Visits: The Implementation Realities of Achieving High Coverage in Large-Scale Programs

Background

Nearly half of births in low-income countries occur without a skilled attendant, and even fewer mothers and babies have postnatal contact with providers who can deliver preventive or curative services that save lives. Community-based maternal and newborn care programs with postnatal home visits have been tested in Bangladesh, Malawi, and Nepal. This paper examines coverage and content of home visits in pilot areas and factors associated with receipt of postnatal visits.

Methods

Using data from cross-sectional surveys of women with live births (Bangladesh 398, Malawi: 900, Nepal: 615), generalized linear models were used to assess the strength of association between three factors - receipt of home visits during pregnancy, birth place, birth notification - and receipt of home visits within three days after birth. Meta-analytic techniques were used to generate pooled relative risks for each factor adjusting for other independent variables, maternal age, and education.

Findings

The proportion of mothers and newborns receiving home visits within three days after birth was 57% in Bangladesh, 11% in Malawi, and 50% in Nepal. Mothers and newborns were more likely to receive a postnatal home visit within three days if the mother received at least one home visit during pregnancy (OR2.18, CI1.46–3.25), the birth occurred outside a facility (OR1.48, CI1.28–1.73), and the mother reported a CHW was notified of the birth (OR2.66, CI1.40–5.08). Checking the cord was the most frequently reported action; most mothers reported at least one action for newborns.

Conclusions

Reaching mothers and babies with home visits during pregnancy and within three days after birth is achievable using existing community health systems if workers are available; linked to communities; and receive training, supplies, and supervision. In all settings, programs must evaluate what community delivery systems can handle and how to best utilize them to improve postnatal care access.
