Promote home exercise discussing how to generalise activity outside of the session; encourage use of a home activity diary; • Graduating appropriate patients to community Phase IV programmes; • Preparing patients for discharge to Phase IV; • Encouraging questions, discussion and social time after cool-down/ recovery; dealing with any questions from partners or family present; • ‘Clerking out’ and review patients at end of session. After the exercise class • Hold team de-brief meeting; – review patients’ clinical status; – discuss and revise exercise prescription and goals, as appropriate; – review potential for onward referral to other team members or health professionals; – agree follow-up plan for non-attendees; – ensure CR resource and referral material and documentation are regularly updated; – plan motivational interview at appropriate stage for patients (see Chapter 8) • Practise local emergency drill; • Plan and encourage regular team education meetings and continuing professional development; • Include relapse prevention by developing coping strategies in anticipa- tion of problems. Discuss adherence difﬁculties, generalise exercise habit to home setting; • Deliver an exercise consultation prior to ﬁnishing phase III (see Chapter 8). Some strate- gies for encouraging a successful transition include: •The phase IV exercise leader comes to the phase III class, meets the graduates and may lead an exercise session of phase III; •The phase III leaders take their graduates to see a phase IV exercise class; •The phase III sessions are held the ﬁrst few weeks in the hospital and then in the community. The phase III leader can gradually pass the par- ticipants to the phase IV leader depending on the participants’ readiness for phase IV. Information to Phase IV It is important that, with the patient’s approval, appropriate information is passed to the phase IV exercise leader: • patient details • GP details • current medical status • previous cardiac status • other health problems • report on phase III participation •medications. When patients attend the reha- bilitation activity session they are under professional instruction and supervi- sion. Exercise should only be undertaken when the following components of care and associated guidelines for clinical practice are in place: supervision by competent staff, appropriately screened patients, individualised exercise prescription, good class management and a safe venue and environment, with ﬁrst aid and emer- gency procedures in place. The following points are collated from recom- mended national clinical guidelines (BACR, 1995; SIGN, 2002;ACPICR, 2003; AACVPR, 2004). There should be appropriate skill mix of professional staff, with specialist training in cardiology, exercise prescription and emergency procedures. There should be a minimum of two trained staff present at all exercise ses- sions, with the ratio of staff to patients dependent on the risk stratiﬁcation of the patients and the level of supervision required by individuals within the group. The current UK recommended ratio is 1:5, cited in British Association for Cardiac Rehabilitation Guidelines (1995), Scottish Inter- collegiate Guidelines (SIGN, 2002) and national guidelines for the Asso- ciation of Physiotherapists in Cardiac Rehabilitation (ACPICR, 2003). All staff should have basic life support training, be able to access and use an automated deﬁbrillator (AED) and to place an emergency crash call to either the hospital resuscitation team or to a 999 ambulance call, depending on exercise venue. Exercise training for high-risk patients should be held in a hospital or venue with immediate access to full resuscitation services and a member of staff trained in advanced life support. There should be a policy to ensure that all staff update resuscitation and AED training annually and hold regular practice drills for emergency procedures. Comprehensive assessment, risk stratiﬁcation and exercise prescription must initially be undertaken with each patient and reviewed and revised as required. There should be local protocols deﬁning inclusion and exclusion criteria for the exercise group, a medical consent procedure to participate in exer- cise and clinical guidelines for excluding a patient with the following con- traindications from exercise (see also Chapter 2): • Unresolved/unstable angina; • New or recurrent symptoms of breathlessness, palpitations, dizziness, swelling of ankles or signiﬁcant lethargy; • Resting systolic blood pressure >200mm/Hg and diastolic >110mm/Hg; • Signiﬁcant unexplained drop in blood pressure; •Tachycardia >100 beats per minute; •Fever and acute systemic illness; 8. All patients should have an exercise induction, be closely observed throughout exercise and for 15 minutes after the cool-down is completed. Ensure that adequate accident and injury insurance cover is in place to conduct an exercise group if the venue is outside hospital premises. Ensure that access points to the venue are safe and unobstructed, with emergency exits clearly signed and ﬁre evacuation procedures in place. Ensure that toilets and changing facilities have an emergency call system in place. Check that the venue lighting, ﬂoor surface and room space are safe and appropriate, allowing adequate space for a free exercise area, safe place- ment of equipment and patient trafﬁc around the exercise room (Tharrett and Peterson, 1997; AACVPR, 2004). CR staff should conduct regular checks on all emergency, ﬁrst aid, exer- cise, BP and HR monitoring machines and audio-visual aid equipment. CR staff are responsible for equipment maintenance procedures and for reporting any problems and faults. Temperature and ventilation of the exercise room should be within acknowledged guidelines, so as to avoid potential health risks imposed by heat stress or a cold environment (ACSM, 2000). Speciﬁcally, temperature should be maintained at 18–23°C (65–72°F), and humidity at 65% (AACVPR, 2004). Drinking water and glucose drinks or supplements should be available at all times. The facility should provide for conﬁdentiality of patients’ records and a private area for conﬁdential patient consultation, if required. There should be rapid access to an emergency team, either hospital crash team or ambulance, and a telephone available for raising emergency help. A written emergency protocol and plan should be clearly displayed in the venue and drawn to people’s attention.
Many are represented among the authors and editors of this excellent book order kamagra soft 100mg overnight delivery, the purpose of which is to enhance understanding of what constitutes the evidence basis for the prac- tice of medical imaging and where that evidence basis is lacking generic kamagra soft 100mg amex. It comes not a moment too soon cheap 100mg kamagra soft fast delivery, given how much is going on in the regulatory and payer worlds concerning health care quality 100 mg kamagra soft overnight delivery. There is a general lack of awareness among radiologists about the insubstantiality of the foundations of our practices cheap kamagra soft 100 mg otc. Through years of teaching medical stu- dents, radiology residents and fellows, and practicing radiologists in various venues, it occurs to me that at the root of the problem is a lack of sophistication in reading the radiology literature. Many clinicians and radi- ologists are busy physicians, who, over time, have taken more to reading reviews and scanning abstracts than critically examining the source of practice pronouncements. Even in our most esteemed journals, literature reviews tend to be exhaustive regurgitations of everything that has been written, without providing much insight into which studies were per- formed more rigorously, and hence are more believable. Radiology train- ing programs spend inordinate time cramming the best and brightest young minds with acronyms, imaging "signs," and unsubstantiated factoids while mostly ignoring teaching future radiologists how to think rigorously about what they are reading and hearing. Rather, the editors and authors have provided ﬁrst a framework for how to think about many of the most important imaging issues of our day, and then ﬂeshed out each chapter with a critical review of the information available in the literature. First, the chapter authors are a veritable "who’s who" of the most thoughtful individuals in our ﬁeld. Reading this book provides a window into how they think as they evaluate the literature and arrive at their conclusions, which we can use as models for our own improvement. Many of the chapters are coauthored by radiologists and practicing clini- cians, allowing for more diverse perspectives. The editors have designed a uniform approach for each chapter and held the authors’ feet to the ﬁre to adhere to it. The literature reviews that follow are selective and critical, rating the strength of the literature to provide insight for the critical reader into the degree of conﬁdence he or she might have in reviewing the conclu- sions. At the end of each chapter, the authors present the imaging approaches that are best supported by the evidence and discuss the gaps that exist in the evidence that should cause us lingering uncertainty. Figures and tables help focus the reader on the most important informa- tion, while decision trees provide the potential for more active engage- ment. At the end of each chapter, bullets are used to highlight areas where there are important gaps in research. The result is a highly approachable text that suits the needs of both the busy practitioner who wants a quick consultation on a patient with whom he or she is actively engaged or the radiologist who wishes a comprehen- sive, in-depth view of an important topic. Most importantly, from my per- spective, the book goes counter to the current trend of "dumbing down" radiology that I abhor in many modern textbooks. To the contrary, this book is an intelligent effort that respects the reader’s potential to think for him- or herself and gives substance to Plutarch’s famous admonition, "The mind is not a vessel to be ﬁlled but a ﬁre to be kindled. Keats Professor of Radiology University of Virginia Preface All is ﬂux, nothing stays still. Medical imaging has grown exponentially in the last three decades with the development of many promising and often noninvasive diagnostic studies and therapeutic modalities. The corresponding medical literature has also exploded in volume and can be overwhelming to physicians. The purpose of this book is to employ stringent evidence-based medicine criteria to systematically review the evidence deﬁning the appropriate use of medical imaging, and to present to the reader a concise summary of the best medical imaging choices for patient care. The 30 chapters cover the most prevalent diseases in developed coun- tries including the four major causes of mortality and morbidity: injury, coronary artery disease, cancer, and cerebrovascular disease. Most of the chapters have been written by radiologists and imagers in close collabo- ration with clinical physicians and surgeons to provide a balanced and fair analysis of the different medical topics. In addition, we address in detail both the adult and pediatric sides of the issues. We cannot answer all ques- tions—medical imaging is a delicate balance of science and art, often without data for guidance—but we can empower the reader with the current evidence behind medical imaging. To make the book user-friendly and to enable fast access to pertinent information, we have organized all of the chapters in the same format. The chapters are framed around important and provocative clinical questions relevant to the daily physician’s practice. A short table of contents at the beginning of each chapter helps three different tiers of users: (1) the busy physician searching for quick guidance, (2) the meticulous physician seeking deeper understanding, and (3) the medical-imaging researcher requiring a comprehensive resource.
