Developing a process model for deployment of radion frequency identification technology (RFID) in hospitals : an action research framework

Radio Frequency Identification (RFlD) technology is increasingly being explored for deployment in hospitals to improve their existing processes. In recent years, RPID pilots has lead to full scale implementation in hospitals, especially for tracking of expensive equipment as well as movable assets that are critical in surgeries. However, academic research is yet to emerge with a generic process model that can be adapted contextually for deployment of RPID in particular hospital settings. In this paper, we propose an action research framework for a pilot implementation of RPID in a large Indian hospital, the experiences of which will contribute to and result, in the development of such a process model.

The case | Allograft dysfunction in a patient with sickle cell disease

The article focuses on the study concerning the diagnosis of acute renal allograft in patient with sickle cell disease. The 33 year old underwent several surgeries with immediate graft function. The percutaneous renal biopsy of the patient shows focal cortical necrosis and acute tubular damage coherent with ischemia. It concludes that the allograft sickling is the primary cause of the acute renal dysfunction in patients with sickle cell disease.

Utilisation of primary total knee joint replacements across socioeconomic status in the Barwon Statistical Division, Australia 2006-7 : a cross-sectional study

Objectives There are few Australian data that examine the association between total knee joint replacement (TKR) utilisation and socioeconomic status (SES). This study examined TKR surgeries with a diagnosis of osteoarthritis (OA) performed for residents of Barwon Statistical Division (BSD) for 2006–2007.

Design Cross-sectional.

Setting BSD, South-eastern Victoria, Australia

Participants All patients who underwent a TKR for OA, 2006–2007, and whose residential postcode was identified as within the BSD of Australia, and for whom SES data were available, were eligible for inclusion.

Primary outcome measure Primary TKR data ascertained from the Australian Orthopaedic Association National Joint Replacement Registry. Residential addresses were matched with the Australian Bureau of Statistics census data, and the Index of Relative Socioeconomic Disadvantage was used to determine SES, categorised into quintiles whereby quintile 1 indicated the most disadvantaged and quintile 5 the least disadvantaged. Age-specific and sex-specific rates of TKR utilisation per 1000 person-years were reported for 10-year age bands.

Results Females accounted for 62.7% of the 691 primary TKR surgeries performed during 2006–2007. The greatest utilisation rates of TKR in males was 7.6 observed in those aged >79 years, and in 10.2 in females observed in those aged 70–79 years. An increase in TKR was observed for males in SES quintile four compared to quintile 1 in which the lowest utilisation which was observed (p=0.04). No differences were observed in females across SES quintiles.

Conclusions Further investigation is warranted on a larger scale to examine the role that SES may play in TKR utilisation, and to determine whether any social disparities in TKR utilisation reflect health system biases or geographic differences.

The frontotemporal-orbitozygomatic approach : reconstructive technique and outcome

Background The frontotemporal-orbitozygomatic (FTOZ) approach, also known as "the workhorse of skull base surgery," has captured the interest of many researchers throughout the years. Most of the studies published have focused on the surgical technique and the gained exposure. However, few studies have described reconstructive techniques or functional and cosmetic outcomes. The goal of this study was to describe the surgical reconstruction after the FTOZ approach and analyze the functional and cosmetic outcomes. Methods Seventy-five consecutive patients who had undergone FTOZ craniotomy for different reasons were selected. The same surgical (one-piece FTOZ) and reconstructive techniques were applied in all patients. The functional outcome was measured by complications related to the surgical approach: retro-orbital pain, exophthalmos, enophthalmos, ocular movement restriction, cranial nerve injuries, pseudomeningocele (PMC) and secondary surgeries required to attain a reconstructive closure. The cosmetic outcome was evaluated by analyzing the satisfaction of the patients and their families. Questionnaires were conducted later in the postoperative period. A statistical analysis of the data obtained from the charts and questions was performed. Results Of the 75 patients studied, 59 had no complications whatsoever. Ocular movement restriction was found in two patients (2.4 %). Cranial nerve injury was documented in seven patients (8.5 %). One patient (1.2 %) underwent surgical repair of a cerebrospinal fluid (CSF) leak from the initial surgery. Two patients (2.4 %) developed delayed postoperative pseudomenigocele. One patient (1.2 %) developed intraparenchymal hemorrhage (IPH). Full responses to the questionnaires were collected from 28 patients giving an overall response rate of 34 %. Overall, 22 patients (78.5 %) were satisfied with the cosmetic outcome of surgery. Conclusion The reconstruction after FTOZ approach is as important as the performance of the surgical technique. Attention to anatomical details and the stepwise reconstruction are a prerequisite to the successful preservation of function and cosmesis. In our series, the orbitozygomatic osteotomy did not increase surgical complications or alter cosmetic outcomes.

Ear wax removal interventions : a systematic review and economic evaluation

Excessive ear wax can lead to symptoms such as hearing loss, tinnitus, itching, vertigo, and pain. Treatment to remove ear wax is generally carried out in primary care, and recent estimates suggest that up to 2 million ear irrigations are performed in England and Wales each year.1 This places a considerable demand on GP surgeries. A range of simple and often inexpensive remedies and proprietary drops can be used either to dissipate the wax orsoften it prior to removal. Although removal through irrigation usually occurs in primary care, some people may self-treat. Treatments offered often appear to be based on custom and local practice, rather than an awareness of the comparative effectiveness and costs of the different alternatives. Although evidence on the efficacy of different treatments has been published, no study has examined both clinical and cost-effectiveness. This report summarises a systematic review and economic evaluation of different approaches to ear wax removal taken from a UK perspective.

Colorectal preOperative surgical score (CrOSS) for mortality in major colorectal surgery

BACKGROUND: Colorectal surgery carries a significant mortality risk, with reported rates of 1-6% for elective surgery and up to 22% in the emergency setting. Both clinicians and patients will benefit from being able to predict the likelihood of death before surgery. Recently, we have described and validated two risk stratification models for colorectal surgery, the Barwon Health 2012 and Association Française de Chirurgie models. However, these models are not suitable for assessment at patient's bedside. The purpose of this study is to develop a simplified preoperative model capable of predicting mortality following colorectal surgery. METHODS: The new model is termed Colorectal preOperative Surgical Score (CrOSS). The development and internal validation of CrOSS was performed using a prospectively maintained colorectal database. External validation was performed using retrospective data. Univariate and multivariate analyses were performed in model development. Calibration and discrimination were used for model validation. RESULTS: There were 474 and 389 consecutive colorectal surgeries at Geelong Hospital and Western Hospital. Overall mortality rates were 5.16% and 1.03%, respectively. Significant predictors for mortality were as follows: age ≥70, urgent operation, albumin ≤30 g/L and congestive heart failure (receiver operating characteristic (ROC) = 0.870, calibration P-value = 0.937). The predicted risk of mortality was stratified according to the risk profile of 0.39-66.51%. When validated externally, CrOSS predicted mortality accurately (ROC = 0.847, calibration P-value = 0.199). CONCLUSIONS: A robust and simple preoperative model has been created to risk-stratify patients for colorectal surgery. This was successfully validated at another tertiary hospital.

Innovation in medical tourism service marketing: A case of India

© 2015, IGI Global. The aim of this chapter is to critically examine the latest development of medical tourism as an innovation in India. The existing theories and concepts in medical tourism are reviewed and synthesised in order to lay down a foundation for marketing managers to deploy marketing mix strategies to deliver values to the medical tourists. A secondary research method is adapted to gather relevant literature. This chapter not only provides a background introduction to the growing importance of the medical tourism industry to the Indian economy, but also makes major contributions: firstly, that global healthcare service marketing is quite different from marketing of other services and goods. Secondly, it proposes to examine the application of 8Ps of tourism marketing-mix along with another 6Ps, such as personalisation of healthcare, publication for patient, patient packaging, patient education, patient privacy, and patient medical and cultural sensitivities for effective marketing of the popular Indian wellness and medical tourism destinations, super-speciality hospitals, and complex diagnostic tests and surgeries to the world.

Struggling with food and eating - life after major upper gastrointestinal surgery

Purpose

Few qualitative studies have explored patients' experience of food and eating following major upper gastrointestinal cancer surgery. The aim of this article was to explore the longer-term impact of different types of major upper gastrointestinal surgeries on people's relationship with food.

Methods

Twenty-six people having had major upper gastrointestinal cancer surgery greater than 6 months ago participated in semi-structured interviews. These interviews aimed to explore a person's physical, emotional and social relationship with food and eating following surgery. Interviews were tape-recorded, transcribed and analysed using an inductive thematic analysis approach.

Results

Interview findings revealed a journey of adjustment, grieving and resignation. The physical symptoms and experiences of people differed between types of surgery, but the coping mechanisms remained the same.

Conclusions

The grieving and resignation people experienced suggest adjustment and coping similar to that of someone with a chronic illness. Remodeling of health services is needed to ensure this patient group receives ongoing management and support.

Simplifying medical additive manufacturing: making the surgeon the designer

Additive Manufacturing, a technology which has been in existence since three decades, is now successfully being transitioned from a research setting to finding technologically and financially viable end-user applications. A key sector in which Additive Manufacturing is being used is the medical devices and healthcare sector. Drivers in this sector include the ability to create customized, patient specific devices and implants with quick turnaround time in a cost-effective manner. Doctors and surgeons are important change agents and innovators in the creation of new healthcare devices as well as surgical methods. Often times, they may find it necessary at first to build devices and plan surgeries which are not even being thought of or acted upon by the major healthcare companies. In this sense, they perform the roles of designers, creating new ideas and improving on them until they can be implemented and adopted by others. However, the scope for performing this creative activity is often limited in their workplaces, with resource, time and financial impediments often being present. Additive Manufacturing can be helpful to speed up the iterative process of designing such medical devices or planning surgeries as well as help convince people outside of the surgery room of the feasibility and business case for such innovations. This paper proposes to introduce a framework of design, processes and tools which will enable non-engineers (specifically surgeons) to create custom-built products. It is hoped that this paper will motivate more surgeons and non-engineers to get involved in the process of designing for additive manufacturing.

The impact of obesity on drug prescribing in primary care

Background

Healthcare costs attributable to obesity have previously involved estimations based on costs of diseases commonly considered as having obesity as an underlying factor.

Aim

To quantify the impact of obesity on total primary care drug prescribing.

Design of study

Review of computer generated and handwritten prescriptions to determine total prescribing volume for all drug classes.

Setting

Twenty-three general practice surgeries in the UK.

Method

Stratified random selection of 1150 patients who were obese (body mass index [BMI]>30 kg/m2) and 1150 age- and sex-matched controls of normal weight (BMI 18.5–<25 kg/m2). Retrospective review of medical records over an 18-month period.

Results

A higher percentage of patients who were obese, compared with those of normal weight, were prescribed at least one drug in the following disease categories: cardiovascular (36% versus 20%), central nervous system (46% versus 35%), endocrine (26% versus 18%), and musculoskeletal and joint disease (30% versus 22%). All of these categories had a P-value of <0.001. Other categories, such as gastrointestinal (24% versus 18%), infections (42% versus 35%), skin (24% versus 19%) had a P-value of <0.01, while respiratory diseases (18% versus 21%) had a P-value of <0.05. Total prescribing volume was significantly higher for the group with obesity and was increased in the region of two- to fourfold in a wide range of prescribing categories: ulcer healing drugs, lipid regulators, β-adrenoreceptor drugs, drugs affecting the rennin angiotensin system, calcium channel blockers, antibacterial drugs, sulphonylureas, biguanides, non-steroidal anti-inflammatories (NSAIDs) (P<0.001) and fibrates, angiotensin II antagonists, and thyroid drugs (P<0.05). The main impact on prescribing volumes is from numbers of patients treated, although in some areas there is an effect from greater dosage or longer treatment in those who are obese including calcium channel blockers, antihistamines, hypnotics, drugs used in the treatment of nausea and vertigo, biguanides, and NSAIDs (P<0.05) reflected in significantly increased defined daily dose prescribing.

Perioperative mortality rates in Australian public hospitals : the influence of age, gender and urgency

INTRODUCTION: A decline in surgical deaths has been observed in Australia since the introduction of the Australian and New Zealand Audit of Surgical Mortality (ANZASM). The current study was conducted to determine whether the perioperative mortality rate (POMR) has also declined. METHODS: This study is a retrospective review of the POMR for surgical procedures in Australian public hospitals between July 2009 and June 2013, using data obtained from the Australian Institute of Health and Welfare. Operative procedures contained in the Australian Refined Diagnosis Related Groups were selected and the POMR was modelled using urgency of admission, age and gender as explanatory covariates. RESULTS: The POMR in Australian public hospitals reduced by 15.4 % over the 4-year period. The emergency admissions POMR dropped from 1.40 to 1.12 %, and the elective admissions POMR from 0.09 to 0.08 %. The binary logistic regression model used to predict patient mortality showed emergency admissions to have a higher POMR than elective, being more evident at older ages. For emergency admissions, the difference in POMR between females and males increased with age, from about 55 years onwards, with females being lower. For elective surgeries, the difference between males and females was of little practical importance across ages. CONCLUSIONS: The reduction in the POMR in Australia confirms the reduction in surgical deaths reported to ANZASM. Continuing to monitor POMR will be important to ensure the safest surgery in Australia. Further investigations into case-mix will allow better risk adjustment and comparison between regions and time-periods, to facilitate continuous quality improvement.
