The nurse's role in immediate postoperative care.

From the time that a patient leaves the care of the anaesthetist after an operation until he wakes in the ward his physiological state should be continuously and expertly supervised. Postoperative nurses are provided only when the operating theatre has a recovery room. A survey among consultants and nurses in one region showed that many surgical units did not have recovery rooms and that inexperienced ward nurses were often sent to collect patients. The survey showed that most nurses were competent to care for unconscious patients so long as an emergency did not arise. In many hospitals the facilities for the safe nursing of postoperative patients were totally inadequate. The very least that is needed is good communications with the anaesthetist, adequate lighting, and a source of oxygen and suction. Because of the shortage of nurses likely to have to care for postanaesthetic patients early on and to train them accordingly. Nevertheless, recovery nurses, whose sole responsibility is to care for a patient until be has recovered from anaesthesia, should be appointed for all busy surgical units.     

Transportation of sick neonates, 1972: an unsatisfactory aspect of medical care

An analysis of personnel and facilities used for transfer of sick newborn infants to the Neonatal Intensive Care Unit of The Hospital for Sick Children, Toronto during the months November 1971 and February to April 1972 showed many deficiencies. In many instances severely ill patients were accompanied by inadequately trained staff, transport incubators were either inadequate to maintain the babies'' temperatures or were used inappropriately, resuscitation facilities were not available and oxygen concentrations could neither be measured nor varied as desired.Infants who weighed less than 1500 g. at birth and who died following transfer had significantly lower mean body temperatures on arrival at the referral hospital than those who survived. Mean transport incubator temperatures were too low in all groups of infants but were lower in those who died, although the difference was not statistically significant.     

Problems of Community Psychiatry

An analysis of existing psychiatric facilities in the community reveals their heterogeneity and fragmentation. Parallel, overlapping and non-communicating, they deal with treatment in a piecemeal fashion and with prevention only by default. Divorce between the different therapeutic phases of what is often the same illness violates any continuity of care. The provincial mental hospital, which arose in part out of social pressure to isolate the “mad” patient, finds itself, often enough, isolated in turn from the community it serves.Greater integration of available treatment resources for the psychiatric patient would serve both his interest and the general concepts of preventive and rehabilitative medicine. An understanding of how this may be achieved may engender social and professional impetus toward the accomplishment. The general hospital is a logical coordinating focus for these facilities and when it has adopted this role this might lead to a greater acceptance of emotional illness by both patients and doctors.     

A Shipping Container-Based Sterile Processing Unit for Low Resources Settings

Deficiencies in the sterile processing of medical instruments contribute to poor outcomes for patients, such as surgical site infections, longer hospital stays, and deaths. In low resources settings, such as some rural and semi-rural areas and secondary and tertiary cities of developing countries, deficiencies in sterile processing are accentuated due to the lack of access to sterilization equipment, improperly maintained and malfunctioning equipment, lack of power to operate equipment, poor protocols, and inadequate quality control over inventory. Inspired by our sterile processing fieldwork at a district hospital in Sierra Leone in 2013, we built an autonomous, shipping-container-based sterile processing unit to address these deficiencies. The sterile processing unit, dubbed “the sterile box,” is a full suite capable of handling instruments from the moment they leave the operating room to the point they are sterile and ready to be reused for the next surgery. The sterile processing unit is self-sufficient in power and water and features an intake for contaminated instruments, decontamination, sterilization via non-electric steam sterilizers, and secure inventory storage. To validate efficacy, we ran tests of decontamination and sterilization performance. Results of 61 trials validate convincingly that our sterile processing unit achieves satisfactory outcomes for decontamination and sterilization and as such holds promise to support healthcare facilities in low resources settings.     

Explaining Adherence Success in Sub-Saharan Africa: An Ethnographic Study

Background

Individuals living with HIV/AIDS in sub-Saharan Africa generally take more than 90% of prescribed doses of antiretroviral therapy (ART). This number exceeds the levels of adherence observed in North America and dispels early scale-up concerns that adherence would be inadequate in settings of extreme poverty. This paper offers an explanation and theoretical model of ART adherence success based on the results of an ethnographic study in three sub-Saharan African countries.

Methods and Findings

Determinants of ART adherence for HIV-infected persons in sub-Saharan Africa were examined with ethnographic research methods. 414 in-person interviews were carried out with 252 persons taking ART, their treatment partners, and health care professionals at HIV treatment sites in Jos, Nigeria; Dar es Salaam, Tanzania; and Mbarara, Uganda. 136 field observations of clinic activities were also conducted. Data were examined using category construction and interpretive approaches to analysis. Findings indicate that individuals taking ART routinely overcome economic obstacles to ART adherence through a number of deliberate strategies aimed at prioritizing adherence: borrowing and “begging” transport funds, making “impossible choices” to allocate resources in favor of treatment, and “doing without.” Prioritization of adherence is accomplished through resources and help made available by treatment partners, other family members and friends, and health care providers. Helpers expect adherence and make their expectations known, creating a responsibility on the part of patients to adhere. Patients adhere to promote good will on the part of helpers, thereby ensuring help will be available when future needs arise.

Conclusion

Adherence success in sub-Saharan Africa can be explained as a means of fulfilling social responsibilities and thus preserving social capital in essential relationships.     

METHODOLOGY IN MEDICAL RESEARCH—The Need for Controlled Clinical Studies

Too many medical researchers vitiate their work by ignoring the problem of uncontrolled variables. They therefore publish clinical impressions “dressed up” in scientifically meaningless numbers. A prototypical example of this practice is contrasted with a controlled study, each employing the same (small) number of patients. It is shown how the use of controls can convert a meaningless experiment into one that has assessable scientific significance.A survey of current literature revealed that in only 21 of 100 articles studied were adequately controlled experimental conditions employed.Since they usually deal with very complex systems, it is urged that medical researchers exercise more scientific rigor with regard to control problems.     

SCREENING TESTS FOR DIABETES DETECTION—Combined with a Chest X-Ray Survey

A program was carried out to test the value and feasibility of performing blood sugar screening tests in conjunction with a community-wide chest x-ray survey. A simple, rapid and inexpensive blood sugar screening test requiring only about two drops of blood from the finger tip was used. Among 14,681 persons who stated that they did not have diabetes, 191 or 1.3 per cent had “positive” results in screening tests. The number of persons referred to their physicians for diagnostic study because of the possibility of diabetes was reduced from 191 to 127 by means of a more specific secondary screening test.Diagnostic information with regard to 102 of the 127 persons referred to their physicians was supplied by the physicians. In 58 (0.40 per cent of the 14,681 participants) the diagnosis was diabetes—newly discovered as a result of referral by the survey.Some of the persons referred to their physicians because of suspicion of diabetes, while not then diabetic, might be considered prediabetic. The appearance of diabetes in this group during the year following the survey was therefore investigated. Glucose tolerance tests were performed for 32 of the diabetes suspects whose diagnosis immediately following the survey was either “not diabetic” or unknown. In 15 cases the glucose tolerance curves were indicative of diabetes, in seven cases questionable and in ten cases normal.The 58 persons diagnosed immediately after the survey plus the 15 found to have “diabetic” glucose tolerance curves a year later made a total of 73 newly discovered diabetics. This is a discovery rate of 0.50 per cent among the 14,681 participants in the survey.The success of this combined diabetes detection and chest x-ray survey suggests that other screening procedures should be studied to determine the desirability of adding them to similar community-wide case-finding programs.     

Quality along the Continuum: A Health Facility Assessment of Intrapartum and Postnatal Care in Ghana

Objective

To evaluate quality of routine and emergency intrapartum and postnatal care using a health facility assessment, and to estimate “effective coverage” of skilled attendance in Brong Ahafo, Ghana.

Methods

We conducted an assessment of all 86 health facilities in seven districts in Brong Ahafo. Using performance of key signal functions and the availability of relevant drugs, equipment and trained health professionals, we created composite quality categories in four dimensions: routine delivery care, emergency obstetric care (EmOC), emergency newborn care (EmNC) and non-medical quality. Linking the health facility assessment to surveillance data we estimated “effective coverage” of skilled attendance as the proportion of births in facilities of high quality.

Findings

Delivery care was offered in 64/86 facilities; only 3-13% fulfilled our requirements for the highest quality category in any dimension. Quality was lowest in the emergency care dimensions, with 63% and 58% of facilities categorized as “low” or “substandard” for EmOC and EmNC, respectively. This implies performing less than four EmOC or three EmNC signal functions, and/or employing less than two skilled health professionals, and/or that no health professionals were present during our visit. Routine delivery care was “low” or “substandard” in 39% of facilities, meaning 25/64 facilities performed less than six routine signal functions and/or had less than two skilled health professionals and/or less than one midwife. While 68% of births were in health facilities, only 18% were in facilities with “high” or “highest” quality in all dimensions.

Conclusion

Our comprehensive facility assessment showed that quality of routine and emergency intrapartum and postnatal care was generally low in the study region. While coverage with facility delivery was 68%, we estimated “effective coverage” of skilled attendance at 18%, thus revealing a large “quality gap.” Effective coverage could be a meaningful indicator of progress towards reducing maternal and newborn mortality.     

Direct Observation (DO) for Drug-Resistant Tuberculosis: Do We Really DO?

Introduction

Directly-observed therapy (DOT) is recommended for drug-resistant tuberculosis (DR-TB) patients during their entire treatment duration. However, there is limited published evidence on implementation of direct observation (DO) in the field. This study aims to detail whether DO was followed with DR-TB patients in a Médecins Sans Frontières (MSF) tuberculosis program in Mumbai, India.

Methods

This was a cross-sectional, mixed-methods study. Existing qualitative data from a purposively-selected subset of 12 patients, 5 DOT-providers and 5 family members, were assessed in order to determine how DO was implemented. A questionnaire-based survey of DR-TB patients, their DOT-providers and MSF staff was completed between June and August 2014. Patients were defined as”following Strict DO” and “following DO” if a DOT-provider had seen the patient swallow his/her medications “every day” or “most of the days” respectively. If DO was not followed, reasons were also recorded. The qualitative data were analysed for theme and content and used to supplement the questionnaire-based data.

Results

A total of 70 DR-TB patients, 65 DOT-providers and 21 MSF health staff were included. Fifty-five per cent of the patients were HIV-co-infected and 41% had multidrug-resistant-TB plus additional resistance to a fluoroquinolone. Among all patients, only 14% (10/70) and 20% (14/70) self-reported “following Strict DO” and “following DO” respectively. Among DOT-providers, 46% (30/65) reported that their patients “followed DO”. MSF health staff reported none of the patients “followed DO”. Reasons for not implementing DO included the unavailability of DOT-provider, time spent, stigma and treatment adverse events. The qualitative data also revealed that “Strict DO” was rarely followed and noted the same reasons for lack of implementation.

Conclusion

This mixed-methods study has found that a majority of patients with DR-TB in Mumbai did not follow DO, and this was reported by patients and care-providers. These data likely reflect the reality of DO implementation in many high-burden settings, since this relatively small cohort was supported and closely monitored by a skilled team with access to multiple resources. The findings raise important concerns about the necessity of DO as a “pillar” of DR-TB treatment which need further validation in other settings. They also suggest that patient-centred adherence strategies might be better approaches for supporting patients on treatment.     

Ruling out pulmonary embolism across different healthcare settings: A systematic review and individual patient data meta-analysis

BackgroundThe challenging clinical dilemma of detecting pulmonary embolism (PE) in suspected patients is encountered in a variety of healthcare settings. We hypothesized that the optimal diagnostic approach to detect these patients in terms of safety and efficiency depends on underlying PE prevalence, case mix, and physician experience, overall reflected by the type of setting where patients are initially assessed. The objective of this study was to assess the capability of ruling out PE by available diagnostic strategies across all possible settings.Methods and findingsWe performed a literature search (MEDLINE) followed by an individual patient data (IPD) meta-analysis (MA; 23 studies), including patients from self-referral emergency care (n = 12,612), primary healthcare clinics (n = 3,174), referred secondary care (n = 17,052), and hospitalized or nursing home patients (n = 2,410). Multilevel logistic regression was performed to evaluate diagnostic performance of the Wells and revised Geneva rules, both using fixed and adapted D-dimer thresholds to age or pretest probability (PTP), for the YEARS algorithm and for the Pulmonary Embolism Rule-out Criteria (PERC). All strategies were tested separately in each healthcare setting. Following studies done in this field, the primary diagnostic metrices estimated from the models were the “failure rate” of each strategy—i.e., the proportion of missed PE among patients categorized as “PE excluded” and “efficiency”—defined as the proportion of patients categorized as “PE excluded” among all patients. In self-referral emergency care, the PERC algorithm excludes PE in 21% of suspected patients at a failure rate of 1.12% (95% confidence interval [CI] 0.74 to 1.70), whereas this increases to 6.01% (4.09 to 8.75) in referred patients to secondary care at an efficiency of 10%. In patients from primary healthcare and those referred to secondary care, strategies adjusting D-dimer to PTP are the most efficient (range: 43% to 62%) at a failure rate ranging between 0.25% and 3.06%, with higher failure rates observed in patients referred to secondary care. For this latter setting, strategies adjusting D-dimer to age are associated with a lower failure rate ranging between 0.65% and 0.81%, yet are also less efficient (range: 33% and 35%). For all strategies, failure rates are highest in hospitalized or nursing home patients, ranging between 1.68% and 5.13%, at an efficiency ranging between 15% and 30%. The main limitation of the primary analyses was that the diagnostic performance of each strategy was compared in different sets of studies since the availability of items used in each diagnostic strategy differed across included studies; however, sensitivity analyses suggested that the findings were robust.ConclusionsThe capability of safely and efficiently ruling out PE of available diagnostic strategies differs for different healthcare settings. The findings of this IPD MA help in determining the optimum diagnostic strategies for ruling out PE per healthcare setting, balancing the trade-off between failure rate and efficiency of each strategy.

Geert-Jan Geersing and colleagues assess the capability of ruling-out pulmonary embolism by available diagnostic strategies across a range of healthcare settings.     

Do Maternal Knowledge and Attitudes towards Childhood Immunizations in Rural Uganda Correlate with Complete Childhood Vaccination?

Improving childhood vaccination coverage and timeliness is a key health policy objective in many developing countries such as Uganda. Of the many factors known to influence uptake of childhood immunizations in under resourced settings, parents’ understanding and perception of childhood immunizations has largely been overlooked. The aims of this study were to survey mothers’ knowledge and attitudes towards childhood immunizations and then determine if these variables correlate with the timely vaccination coverage of their children. From September to December 2013, we conducted a cross-sectional survey of 1,000 parous women in rural Sheema district in southwest Uganda. The survey collected socio-demographic data and knowledge and attitudes towards childhood immunizations. For the women with at least one child between the age of one month and five years who also had a vaccination card available for the child (N = 302), the vaccination status of this child was assessed. 88% of these children received age-appropriate, on-time immunizations. 93.5% of the women were able to state that childhood immunizations protect children from diseases. The women not able to point this out were significantly more likely to have an under-vaccinated child (PR 1.354: 95% CI 1.018–1.802). When asked why vaccination rates may be low in their community, the two most common responses were “fearful of side effects” and “ignorance/disinterest/laziness” (44% each). The factors influencing caregivers’ demand for childhood immunizations vary widely between, and also within, developing countries. Research that elucidates local knowledge and attitudes, like this study, allows for decisions and policy pertaining to vaccination programs to be more effective at improving child vaccination rates.     

Breast Cancer “Tailored Follow-up” in Italian Oncology Units: A Web-Based Survey

Purpose

Breast cancer follow-up procedures after primary treatment are still a controversial issue. Aim of this study was to investigate, through a web-based survey, surveillance methodologies selected by Italian oncologists in everyday clinical practice.

Methods

Referents of Italian medical oncology units were invited to participate to the study via e-mail through the SurveyMonkey website. Participants were asked how, in their institution, exams of disease staging and follow-up are planned in asymptomatic women and if surveillance continues beyond the 5^th year.

Results

Between February and May 2013, 125 out of 233 (53.6%) invited referents of Italian medical oncology units agreed to participate in the survey. Ninety-seven (77.6%) referents state that modalities of breast cancer follow-up are planned according to the risk of disease progression at diagnosis and only 12 (9.6%) oncology units apply the minimal follow-up procedures according to international guidelines. Minimal follow-up is never applied in high risk asymptomatic women. Ninety-eight (78.4%) oncology units continue follow-up in all patients beyond 5 years.

Conclusions

Our survey shows that 90.4% of participating Italian oncology units declare they do not apply the minimal breast cancer follow-up procedures after primary treatment in asymptomatic women, as suggested by national and international guidelines. Interestingly, about 80.0% of interviewed referents performs the so called “tailored follow-up”, high intensity for high risk, low intensity for low risk patients. There is an urgent need of randomized clinical trials able to determine the effectiveness of risk-based follow-up modalities, their ideal frequency and persistence in time.     

Modes of Admission to Hospital: A Survey of Emergency Admissions to a General Medical Unit

In a survey of the modes of referral and disposal of “acute patients” to a general medical unit during the period 1 February 1968 to 31 July 1970 only 1,432 out of 3,455 were referred by general practitioners. There was a high incidence of self-referral to hospital, and this trend was on the increase. A large percentage of self-referred patients came from their homes, and 65-77% of these arrived by ambulance ordered by themselves.     

Non-Tuberculous Chest Disease Found in a Mass X-Ray Survey in Vancouver,B.C

In 1964, 219,085 persons were examined during a tuberculosis survey in Vancouver, B.C. One hundred and fifteen new cases of tuberculosis and 929 cases of significant non-tuberculous lung disease were found. In a four-month follow-up of the non-tuberculous cases it was found that of the 742 patients who had named a physician when examined 26.6% had not made contact with him. Of those who did contact the physician, the follow-up was considered “poor” in only 30 patients (2.1%). Seventeen patients had died in the four-month interval and 81 who could not be located after the initial survey were considered “lost”. Rates were determined for 37 diagnoses per 1000 patients screened. The most common diagnosis was localized pulmonary fibrosis (1.69/1000). Carcinoma was found in 0.30/1000 and solitary lung density in 0.17/1000 population screened.     

Specific IgM Antibody in Serum of Patients with Herpes Zoster Infections

Specific IgM varicella-zoster antibody was detected in “convalescent” sera from 20 out of 40 patients (50%) with herpes zoster infections. Since these were not primary infections with varicella-zoster virus, it seems that detection of IgM antibody specific for a particular virus may not differentiate a primary infection from secondary infections with that virus.     

Fibrosing Alveolitis Associated with Renal Tubular Acidosis

The discovery of a case of renal tubular acidosis and fibrosing alveolitis led to the investigation of 19 further patients. Abnormal pulmonary function tests were found in a further four patients with overt renal tubular acidosis and in four out of eight patients with “incomplete” renal tubular acidosis. The response to an ammonium chloride test in seven patients with cryptogenic fibrosing alveolitis was normal. Those patients with a defect of both renal acidification and pulmonary gas transfer had concurrent autoimmune diseases such as Sjögren''s syndrome and primary biliary cirrhosis. It is suggested that the renal and pulmonary abnormalities may be part of a systemic disorder capable of affecting many organs. Moreover, hyperglobulinaemia and autoantibodies in these patients further suggests that immunological mechanisms are concerned in the pathogenesis of these abnormalities.     

Options for Optimal Coverage of Free C-Section Services for Poor Mothers in Indian State of Gujarat: Location Allocation Analysis Using GIS

Background

Gujarat, a western state of India, has seen a steep rise in the proportion of institutional deliveries over the last decade. However, there has been a limited access to cesarean section (C-Section) deliveries for complicated obstetric cases especially for poor rural women. C-section is a lifesaving intervention that can prevent both maternal and perinatal mortality. Poor women bear a disproportionate burden of maternal mortality, and lack of access to C-section, especially for these women, is an important contributor for high maternal and perinatal mortality in resource limited settings. To improve access for this underserved population in the context of inadequate public provision of emergency obstetric services, the state government of Gujarat initiated a public private partnership program called “Chiranjeevi Yojana” (CY) in 2005 to increase the number of facilities providing free C-section services. This study aimed to analyze the current availability of these services in three districts of Gujarat and to identify the best locations for additional service centres to optimize access to free C-section services using Geographic Information System technology.

Methodology

Supply and demand for obstetric care were calculated using secondary data from sources such as Census and primary data from cross-sectional facility survey. The study is unique in using primary data from facilities, which was collected in 2012–13. Information on obstetric beds and functionality of facilities to calculate supply was collected using pretested questionnaire by trained researchers after obtaining written consent from the participating facilities. Census data of population and birth rates for the study districts was used for demand calculations. Location-allocation model of ArcGIS 10 was used for analyses.

Results

Currently, about 50 to 84% of populations in all three study districts have access to free C-section facilities within a 20km radius. The model suggests that about 80–96% of the population can be covered for free C-section services with addition of 4–6 centres in critical but underserved regions. It was also suggested that upgrading of public sector facilities with minimal investment can improve the services.

Conclusion

This study highlights utility of Geographic Information System technology for planning service centres to optimize access to vital lifesaving procedure such as C-section. Although the location allocation methodology has been available for decades, it has been used sparsely by public health professionals. This paper makes an important contribution to the literature for use of the method for planning in resource limited settings.     

Psychiatry in the Soviet Union

The services for chronically handicapped people with psychiatric disorders in the Soviet Union are described. The system is based upon a network of community units, each of which includes a day centre, a follow-up clinic, and a sheltered workshop. British services could profitably learn from the experience of these units. The diagnostic system used by many Soviet psychiatrists is different from that incorporated in the International Classification of Diseases. In particular, the term “schizophrenia” is used to describe conditions which British psychiatrists would label in other ways.This clinical difference partly explains the different concept of “criminal responsibility,” but another large component of the difference is political rather than medical. There are also variations from British practice in certain juridical procedures. These differences together make Soviet psychiatric practice in the case of political dissenters unacceptable to most British psychiatrists. It is too soon to say that frank discussions of these matters could not lead to improvement. British and Soviet psychiatrists still have something to learn from each other.
